Abstract Introduction: Propofol is a widely used anesthetic and its dose is closely related to aging. Telomere length (TL) is a unique heritable trait, and emerging as a biomarker of aging, health and disease. Telomerase RNA component (TERC) plays an important role in maintaining TL. We proposed a hypothesis that propofol dose in general anesthesia can be predicted by measuring TL before operation, which greatly reduced the risk of anesthesia, especially the elderly. Methods: The association between the propofol dose in anesthesia induction and: TL in the DNA of peripheral blood leukocytes; body weight; sex; difference of the Bispectral Index (BIS) before and after anesthesia induction in patients was evaluated by multivariable linear regression analyses. The mutation at the 5’end or 3’end of TERC was detected. We recruited 100 patients of elective surgery. Results: We found that propofol dose in anesthesia induction was clearly correlated significantly with TL (r = 0.78, p < 0.001), body weight (r = 0.84, p = 0.004), sex (r = 0.83, p= 0.84, p = 0.004), sex (r = 0.83, p = 0.004), and difference of BIS before and after anesthesia induction (r = 0.85, p = 0.029). By comparing the absolute values of standardized regression coefficients (0.58, 0.21, 0.19, and 0.12) of the four variables, it can be seen that TL contributes the most to the propofol dose in anesthesia induction. However, the mutation at the 5’ end or 3’ end of TERC was not found. Conclusions: These findings provide preliminary evidence that the propofol dose in anesthesia induction was clearly correlated with genetically determined TL. TL may be a promising predictor of the propofol dose, which is beneficial to improve the safety of anesthesia and reduce perioperative complications.

Abstract Objectives: The degree of endolymphatic hydrops in Meniere’s disease may be related to hearing loss. However, the results of prior studies have been inconsistent. We aimed to investigate the relationship between endolymphatic hydrops and hearing loss characteristics in Meniere’s disease. Methods: This study included 54 patients (62 ears) with Meniere’s disease. Patients underwent three-dimensional real inversion recovery sequences for magnetic resonance imaging and puretone audiometry. Endolymphatic hydrops were assessed according to Gurkov’s criteria (2011). Correlations between different degrees of endolymphatic hydrops and pure-tone audiometry, as well as staging, were analysed. Results: Pure tone audiometry and staging were higher for vestibular endolymphatic hydrops complicated by cochlear ones than isolated cochlear or vestibular hydrops (both p<0.05). There was no significant correlation between vestibular endolymphatic hydrops and pure-tonal audiometry or staging (all p > 0.05). The degree of hydrops in the middle turn was correlated with the mid-frequency hearing threshold (p<0.05). The degree of cochlear hydrops was correlated with the audiometry, low-frequency hearing thresholds, mid-frequency hearing thresholds and staging (p<0.01). Conclusion: The types and sites of endolymphatic hydrops based on a 3D-real inversion recovery sequence can be used to indicate the degree of hearing loss in patients with Meniere's disease. Level of evidence: Level III.

Abstract Introduction: chronic inflammation contributes to a wide range of metabolic disorders through the influence of diet. The dietary inflammatory index (DII) was developed to measure the inflammation potential of diet. Objectives: Uygur adults have a high prevalence of obesity, but the causes of this condition remain unclear. In this study we investigated the association between DII and adipocytokines among overweight and obese Uygur adults. Methods: a total of 283 obese and overweight Uygur adults were included. Sociodemographic characteristics, anthropometric measurements, dietary surveys and biochemical indicators were collected by standardized protocols. The DII score was calculated using a valid and reliable 93-item food frequency questionnaire (FFQ). Linear regression was used to estimate the relationship between DII and adipocytokines. Results: the DII score was 1.35 ± 1.08, ranging from -2.14 to +3.11. There was a significant inverse correlation between DII and high-density lipoprotein cholesterol (HDL-C) in the unadjusted model (β = -0.12, p = 0.02), and this remained after adjustment for age, gender, body mass index (BMI). DII was negatively associated with adiponectin (ADPN) (β = -203.15, p = 0.04) and positively associated with leptin (LEP) concentration (β = 1.64, p = 0.002) after adjustment for age, gender and BMI. Conclusion: a pro-inflammatory diet, as indicated by a higher DII score, is associated with adipose tissue inflammation in Uygur adults and supports the hypothesis that diet may play a role in the development of obesity through inflammatory modulation mechanisms. A healthy anti-inflammatory diet is feasible for obesity intervention in the future.

Resumen Introducción: la inflamación crónica causa múltiples trastornos metabólicos a través de la influencia de la dieta. El índice de inflamación dietética (DII) se estableció para medir el potencial inflamatorio de la dieta. Objetivo: los adultos de Uygur presentan una alta prevalencia de obesidad, pero las causas de esta condición aún no están claras. En el presente estudio se investigó la relación entre DII y adipocitocinas en adultos uigur con sobrepeso y obesidad. Métodos: se incluyeron 283 adultos de Uygur obesos y con sobrepeso. Las características sociodemográficas, antropométricas, dietéticas y bioquímicas se recogieron mediante un protocolo estandarizado. El índice DII se calculó utilizando un cuestionario de frecuencia alimentaria (FFQ) válido y fiable de 93 elementos. Se realizó una regresión lineal para estimar la relación entre DII y adipocitocinas. Resultados: la puntuación DII fue de 1,35 ± 1,08 y osciló entre -2,14 y +3,11. En el modelo no ajustado hubo una correlación negativa significativa entre DII y colesterol lipoproteínico de alta densidad (HDL-C) (β = -0,12, p = 0,02) que permaneció después de ajustar la edad, el sexo y el índice de masa corporal (IMC). Después de ajustar la edad, el sexo y el IMC, el DII se correlacionó negativamente con la concentración de adiponectina (β = - 203,15, p = 0,04) y positivamente con la concentración de leptina (β = 1,64, p = 0002). Conclusión: las puntuaciones más altas de DII sugieren que la dieta proinflamatoria está relacionada con la inflamación del tejido adiposo en los adultos de Uygur, y apoyan la hipótesis de que la dieta puede desempeñar un papel en el desarrollo de la obesidad a través del mecanismo de regulación de la inflamación. La dieta antiinflamatoria saludable es factible para futuras intervenciones de obesidad.

SUMMARY: This study is to investigate the effect of home-based cardiac rehabilitation (HBCR) on quality of life, functional capacity, and readmission rates in patients with heart failure. Randomized controlled trials (RCTs) were screened from Cochrane Library, CINAHL, EMBASE, and MEDLINE. The intervention group received a standardized HBCR or a comprehensive rehabilitation strategy that included HBCR. The participants in the control group received CR at a medical center or usual care without CR intervention. The main outcome measurements included quality of life, exercise capacity, mortality and re-hospitalization. This meta-analysis included 20 RCTs, in which 16 studies compared HBCR with usual care, and 4 studies compared HBCR with center-based CR. In comparison with the usual care, HBCR improved the total quality of life score [MD=-5.85, 95 % CI (-9.76, - 1.94), P=0.003, I2=75 %]. Patients with HBCR and usual care were significantly different in VO2max [MD=1.05 mL/kg/min, 95 % CI (0.35, 1.75), P=0.003, I2=46 %]. However, VO2max of patients with HBCR was not significantly different from those with center-based CR [MD=0.08 mL/kg/min, 95 % CI (-1.29, 1.44), P=0.91, I2=0 %]. There was statistically significant difference in the 6-min Walk Distance between usual care and HBCR (for distance [MD=11.84, 95 % CI (7.41, 16.28), P<0.00001, I2=0 %]; and for feet [MD=98.93, 95 % CI (26.79, 171.08), P=0.007, I2=56 %]). However, there was no significant difference in 6-min Walk Distance between patients with HBCR and center-based CR [MD=12.45, 95 % CI (-9.81, 34.72), P=0.27, I2=0 %] , or in anxiety and depression between patients with usual care and HBCR (for anxiety, [MD=-0.25, 95 % CI (-0.56, 0.05), P=0.11, I2=0 %]; for depression, [MD=-0.18, 95 % CI (-0.51, 0.16), P=0.30, I2=0 %] . No significant difference was found in death number [RR=1.04, 95 % CI (0.55, 1.98), P=0.90, I2=0 %] or in the number of re-hospitalization [RR=0.88, 95 % CI (0.66, 1.18), P=0.40, I2=0 %] between usual care and HBCR. For patients with heart failure, compare with usual care and center-based CR, HBCR can improve the total quality of life. Compare with usual care, HBCR can improve VO2max and 6-min Walk Distance, but compare with center- based CR, there are no differences in mortality, re-hospitalization rate or incidence of anxiety and depression. Additionally, center- based CR and HBCR showed similar outcomes and medical costs.

RESUMEN: El objetivo de este estudio fue investigar el efecto de la rehabilitación cardíaca domiciliaria (HBCR) sobre la calidad de vida, la capacidad funcional y las tasas de reingreso en pacientes con insuficiencia cardíaca. Se seleccionaron ensayos controlados aleatorios (ECA) de la Biblioteca Cochrane, CINAHL, EMBASE y MEDLINE. El grupo de intervención recibió un HBCR estandarizado o una estrategia de rehabilitación integral que incluía HBCR. Los participantes del grupo de control recibieron RC en un centro médico o atención habitual sin intervención de RC. Las principales medidas de resultado incluyeron la calidad de vida, la capacidad de ejercicio, la mortalidad y la rehospitalización. Este metanálisis incluyó 20 ECA, en los que 16 estudios compararon HBCR con la atención habitual y 4 estudios compararon que mejoró la puntuación total de calidad de vida [DM=-5,85, IC del 95 % (-9,76, -1,94), P=0,003, I2=75 %]. Los pacientes con HBCR y atención habitual fueron significativamente diferentes en el VO2máx [DM = 1,05 ml/kg/ min, IC del 95 % (0,35, 1,75), P = 0,003, I2 = 46 %]. Sin embargo, el VO2max de los pacientes con HBCR no fue significativamente diferente de aquellos con CR basada en el centro [DM = 0,08 ml/kg/min, IC del 95 % (-1,29, 1,44), P = 0,91, I2 = 0 %]. Hubo una diferencia estadísticamente significativa en la distancia de caminata de 6 minutos entre la atención habitual y HBCR (para la distancia [DM=11,84, IC del 95 % (7,41, 16,28), P<0,00001, I2=0 %]; y para los pies [DM= 98,93, IC 95 % (26,79, 171,08), P=0,007, I2=56 %]). Sin embargo, no hubo una diferencia significativa en la distancia de caminata de 6 minutos entre los pacientes con HBCR y CR basada en el cen- tro [DM = 12,45, IC del 95 % (-9,81, 34,72), P = 0,27, I2 = 0 %], o en la ansiedad y depresión entre pacientes con atención habitual y HBCR (para ansiedad, [DM=-0,25, IC del 95 % (-0,56, 0,05), P=0,11, I2=0 %]; para depresión, [DM=-0,18, 95 % IC (- 0,51, 0,16), P=0,30, I2=0 %] No se encontraron diferencias significativas en el número de muertes [RR=1,04, IC del 95 % (0,55, 1,98), P=0,90, I2=0 %] o en el número de reingresos [RR=0,88, IC 95 % (0,66, 1,18), P=0,40, I2=0 %] entre atención habitual y HBCR. Para los pacientes con insuficiencia cardíaca, en comparación con la atención habitual y la CR en un centro, la HBCR puede mejorar la calidad de vida total. En comparación con la atención habitual, la HBCR puede mejorar el VO2máx y la distancia recorrida en 6 minutos, pero en comparación con la CR basada en un centro, no hay diferencias en la mortalidad, la tasa de rehospitalización o la incidencia de ansiedad y depresión. Además, CR y HBCR basados en el centro mostraron resultados y costos médicos similares.

Abstract Objective: This study aimed to perform a meta-analysis to investigate the diagnostic safety and accuracy of Ultrasound-Guided Core Needle Biopsy (US-CNB) Axillary Lymph Nodes (ALNs) region in patients with Breast Cancer (BC). Methods: The authors searched the electronic databases PubMed, Scopus, Embase, and Web of Science for clinical trials about US-CNB for the detection of ALNs in breast cancer patients. The authors extracted and pooled raw data from the included studies and performed statistical analyses using Meta-DiSc 1.4 and Review Manager 5.3 software. A random effects model was used to calculate the data. At the same time, data from the Ultrasound-guided Fine-Needle Aspiration (US-FNA) were introduced for comparison with the US-CNB. In addition, the subgroup was performed to explore the causes of heterogeneity. (PROSPERO ID: CRD42022369491). Results: In total, 18 articles with 2521 patients were assessed as meeting the study criteria. The overall sensitivity was 0.90 (95% CI [Confidence Interval], 0.87‒0.91; p = 0.00), the overall specificity was 0.99 (95% CI 0.98‒ 1.00; p = 0.62), the overall area under the curve (AUC) was 0.98. Next, in the comparison of US-CNB and US-FNA, US-CNB is better than US-FNA in the diagnosis of ALNs metastases. The sensitivity was 0.88 (95% CI 0.84‒ 0.91; p = 0.12) vs. 0.73 (95% CI 0.69‒0.76; p = 0.91), the specificity was 1.00 (95% CI 0.99‒1.00; p = 1.00) vs. 0.99 (95% CI 0.67‒0.74; p = 0.92), and the AUC was 0.99 vs. 0.98. Subgroup analysis showed that heterogeneity may be related to preoperative Neoadjuvant Chemotherapy (NAC) treatment, region, size of tumor diameter, and the number of punctures. Conclusion: US-CNB has a satisfactory diagnostic performance with good specificity and sensitivity in the preoperative diagnosis of ALNs in BC patients.

Abstract Background Complete thrombosis of the false lumen facilitates remodeling of type B aortic dissection (TBAD). Morphological characteristics affect thrombosis in the false lumen. Objectives Discuss the factors present before admission that influence false lumen thrombosis in patients with TBAD. Methods We studied 282 patients diagnosed with TBAD in our hospital between January 2008 and December 2017. We divided the subjects into a thrombotic group and a non-thrombotic group based on whether any thrombus was detectable in the false lumen. We analyzed the differences between the two groups with respect to clinical data, the vertical length of the dissection, and the diameter of the aorta. P values < 0.05 were considered statistically significantly different. Results Significant differences between the thrombotic group and non-thrombotic group were found with respect to age (53.92 ± 11.40 vs. 50.36 ± 10.71, p = 0.009) and proportion of patients with renal insufficiency (7.83% vs. 16.38%, p = 0.026). In zones 3–9, the true lumen diameter of the thrombotic group was significantly larger than in the non-thrombotic group (p < 0.05). Binary logistic regression analysis showed that true lumen diameter in zone 5 and renal insufficiency were independent predictors of false lumen thrombosis. Conclusions Age and renal function were associated with thrombosis in the false lumen. Potentially, the difference between the diameter of the true lumen diameter and that of the false lumen may influence the thrombosis of the false lumen.

Resumo Fundamento A trombose completa da falsa luz facilita a remodelação da dissecção aórtica tipo B (DATB). As características morfológicas afetam a trombose na falsa luz. Objetivos Discutir os fatores pré-admissão presentes, que influenciam a trombose da falsa luz em pacientes com DATB. Metodologia Ao todo, 282 pacientes diagnosticados com DATB em nosso hospital foram estudados, no período entre janeiro de 2008 e dezembro de 2017. Os indivíduos foram divididos em um grupo trombótico e um grupo não trombótico, com base na detecção de qualquer trombo na falsa luz. Analisamos as diferenças entre os dois grupos com relação aos dados clínicos, o comprimento vertical da dissecção e o diâmetro da aorta. Valores de p < 0,05 foram considerados estatisticamente diferentes de modo significativo. Resultados Diferenças significativas entre o grupo trombótico e o grupo não trombótico foram encontradas com relação à idade (53,92 ± 11,40 vs. 50,36 ± 10,71, p = 0,009) e proporção de pacientes com insuficiência renal (7,83% vs. 16,38%, p = 0,026). Nas zonas 3–9, o diâmetro da luz verdadeira do grupo trombótico foi significativamente maior do que no grupo não trombótico (p < 0,05). A análise de regressão logística binária mostrou que o diâmetro da luz verdadeira na zona 5 e a insuficiência renal foram preditores independentes de trombose da falsa luz. Conclusões A idade e a função renal estiveram associadas à trombose na falsa luz. Potencialmente, a diferença entre o diâmetro da luz verdadeira e o da falsa luz pode influenciar na trombose da falsa luz.

Abstract Objective At present, bleomycin has been widely used in the treatment of Lymphatic Malformations (LMs). This study aims to perform a meta-analysis to investigate the effectiveness and influencing factors of bleomycin in the treatment of LMs. Methods We conducted a systematic review and meta-analysis to clarify the relationship between bleomycin and LMs. PubMed, ISI Web of Science and MEDLINE were searched. Results A total of 21 studies (including 428 cases) about bleomycin sclerotherapy for LMs were included in the current meta-analyses. We calculated pooled effective rate and 95% Confidence Interval (95% CI) using random effects model to evaluate the relations between bleomycin and LMs. The results suggested that the effective rate of bleomycin was the combined effective rate was 84.0% (95% CI 0.81‒0.87) and ranged from 39% (95% CI 0.22‒0.56) to 94% (95% CI 0.87-1.02). The heterogeneity among the studies was substantial (I2 = 61.7%, p = 0.000). In subgroup analyses, it was observed that among retrospective study and prospective study, the estimated effective rate was 80.0% (95% CI 0.76‒0.84) and 91.0% (95% CI 0.85‒0.97), respectively. In terms of the dosage, the combined effective rates of weight-based group and fixed-dose group were 86% (95% CI 0.83‒0.90) and 74.0% (95% CI 0.66‒0.82), respectively. There was no significant publication bias in Egger's test (p = 0.059, 95% CI −3.81 to 0.082), but Begg's test did (p = 0.023), and the funnel plot is asymmetric. Conclusion Our study suggested that bleomycin was safe and effective in the treatment of LMs and was primarily dose dependent.

Abstract Objective: To investigate the factors influencing hyperuricemia in children and adolescents and to provide a scientific basis for early prevention and treatment. Methods: A retrospective study (2017-2021) of the prevalence of hyperuricemia in children and adolescents was conducted, and the factors influencing hyperuricemia were analyzed by multifactor logistic regression. Results: The overall prevalence of hyperuricemia in children and adolescents aged 6-17 years in northeast Sichuan Province was 55.12% (8676/15,739), of which 60.68% (5699/9392) in boys and 46.90% (2977/6347) in girls; the prevalence of hyperuricemia from 2017 to 2021 was 52.40% ( 1540/2939), 52.56% (1642/3124), 52.11% (1825/3502), 58.33% (1691/2899), and 60.40% (1978/ 3275), respectively; the prevalence rates of 6-12 years old were 48.92% (864/1766), 50.46% (769/1524), and 52.73% (685/1299), 56.99% (693/1216), 35.46% (444/1252), 46.33% (524/1131), 60.50% (720/1190), and 66.82% (739/1106), 58.95% (652/1106), and 62.17% (761/1106) for 13-17 years old, respectively, 62.17% (761/1224), 63.19% (855/1353), and 61.70% (970/1572), respectively. Logistic regression showed that the prevalence of male (OR = 1.451, 95% CI 1.034 to 2.035, p = 0.031), age (OR = 1.074, 95% CI 1.024 to 1.126, p = 0.003), overweight/obesity (OR = 1.733, 95% CI 1.204~2.494, p = 0.003), blood creatinine (OR = 1.018, 95% CI 1.005~1.031, p = 0.007), triglycerides (OR = 1.450, 95% CI1.065~1.972, p = 0.018), blood calcium (OR = 6.792, 95% CI 1.373~33.594, p = 0.019), and systolic blood pressure (OR = 1.037, 95% CI 1.018~1.057, p < 0.001) were influential factors for the development of hyperuricemia. Conclusion: The prevalence of hyperuricemia was higher in children and adolescents aged 6-17 years in northeastern Sichuan Province, with a higher prevalence in boys than in girls, and the prevalence increased with age.

Abstract Background Currently, only a few studies have described the general characteristics of patients with primary Sjögren's syndrome (pSS) who tested negatives for anti-SSA and anti-SSB antibodies. We aimed to further investigate the clinical characteristics of these patients in a large sample. Methods Data from patients with pSS who were treated at a tertiary hospital in China between 2013 and 2022 were retrospectively analyzed. Clinical characteristics of the patients were compared between those with and without anti-SSA and anti-SSB antibody negativity. Factors associated with anti-SSA and anti-SSB negativity were identified by logistic regression analysis. Results Overall, 934 patients with pSS were included in this study, among whom 299 (32.0%) tested negative for anti-SSA and anti-SSB antibodies. Compared with patients testing positive for anti-SSA or anti-SSB antibodies, that testing negative for the two antibodies had a lower proportion of females (75.3% vs. 90.6%, p < 0.001) and thrombocytopenia (6.7% vs. 13.6%, p = 0.002), but a higher proportion of abnormal Schirmer I tests (96.0% vs. 89.1%, p = 0.001) and interstitial lung disease (ILD) (59.2% vs. 28.8%, p = 0.001). Anti-SSA and anti-SSB negativity was positively associated with male sex (odds ratio [OR] = 1.86, 95% confidence interval [CI]: 1.05, 3.31), abnormal Schirmer I tests (OR = 2.85, 95% CI: 1.24, 6.53), and ILD (OR = 2.54, 95% CI: 1.67, 3.85). However, it was negatively related to thrombocytopenia (OR = 0.47, 95% CI: 0.24, 0.95). Conclusion Approximately one third of pSS patients had anti-SSA and anti-SSB negativity. pSS patients testing negative for anti-SSA and anti-SSB showed a higher risk of abnormal Schirmer I tests and ILD, but a lower risk of thrombocytopenia.

Abstract Objective: The objective of the study was to systematically evaluate the effect of coronary artery bypass grafting (CABG) or CABG combined with mitral valve surgery (cMVS) on post-operative survival in patients with moderate ischemic mitral valve regurgitation. Materials and methods: Databases including PubMed, Web of Science, COCHRANE LIBRARY, WanFang Data, and CNKI Data were searched from inception to January 2020. According to the inclusion criterion, relevant articles were screened. After that we extracted data, assessed quality, and performed meta-analysis using RevMan 5.2. Results: A total of 4 randomized controlled trial and 14 retrospective study involving 4476 patients were included in the study. The CABG group was 2278 and the cMVS group was 1698. The results of meta-analysis showed that compared with CABG group, there were no statistically significant differences in the recent mortality (odds ratio [OR] = 0.88, p = 0.62), 1-year survival (OR = 1.03, p = 0.82), 1-year survival (OR = 1.07, p = 0.62), and long-term survival (OR = 0.95, p = 0.61) of the cMVS group. Conclusion: Current evidence indicates that patients in the cMVS group did not benefit from CABG group in survival after surgery.

Abstract In this study, we aimed to compare clinical efficacy of laparoscopic surgery and open surgery for colorectal cancer in the Huaihe River Basin in China. A total of 92 patients with colorectal cancer were selected as subjects. Patients were divided into control group (open surgery, n = 27 cases) and test group (laparoscopic surgery, n = 28 cases). Our results showed that the duration of operation (122.54 ± 14.85) min and length of incision (4.51 ± 1.065) cm were shorter in the experimental group than those in the control group. The intraoperative blood loss of the experimental group was (161.12 ± 10.694) ml, which was less than that of the control group (218.53 ± 15.369) ml (P < 0.05). Patients in the experimental group have higher Five-year survival rate and lower incidence of postoperative complications than those in the control group (all P < 0.05). In conclusion, in the treatment of colorectal cancer, laparoscopic surgery has a better clinical effect than open surgery, which is worthy of clinical application.

Abstract Character strengths could effectively prevent negative psychological outcomes in adults. However, there was little research conducted among early adolescents. The present study aimed to explore character strengths that were independently related to fewer behavior problems in early adolescents. In total, 521 early adolescents (mean age 10.92 ± 0.04, range 10–12 years) were recruited from primary schools in Sichuan, China. Character strengths were measured using the Values in Action Inventory of Strengths for Youth (VIA-Youth). Behavior problems were measured using the Conners Parent Symptom Questionnaire (PSQ). The results showed that behavior problems were negatively correlated with character strengths ( r = −0.14 to −0.3, p < 0.05 Bonferroni corrected). Character strengths explained a significant proportion of additional variance (14–22%) in five types of behavior problems after controlling the effect of demographic factors (residence, left-behind experiences, maternal education level). Moreover, several specific character strengths showed an independent contribution ( β = −0.34 to −0.14 for self-regulation, perseverance, zest, humility, and leadership; β = 0.21 to 0.34, for hope; all p < 0.05) to behavior problems. Our study revealed that character strengths were protective factors against behavior problems in early adolescents.

Resumo Fundamento A relação direta entre a doença arterial coronariana (DAC) e o câncer de pulmão não é bem conhecida. Objetivo Investigar a associação entre a gravidade anatômica da DAC e do câncer de pulmão. Métodos Trezentos pacientes, incluindo 75 recém-diagnosticados com câncer de pulmão e 225 pacientes correspondentes sem câncer, foram submetidos à angiografia coronária durante a internação, sem intervenção coronária percutânea (ICP) prévia nem enxerto de bypass da artéria coronária (CABG). O escore SYNTAX foi utilizado para avaliar a gravidade da DAC. Uma pontuação alta no escore foi definida como > 15 (o maior quartil do escore SYNTAX). O teste de tendência de Cochran-Armitage foi utilizado para verificar a distribuição dos escores dos pacientes. Uma análise de regressão logística foi utilizada para avaliar a associação entre a gravidade da DAC e o câncer de pulmão. Os valores de p foram estabelecidos quando o nível de significância era 5%. Resultados A tendência de distribuição dos escores SYNTAX dos pacientes por quartis foi diferente entre aqueles com câncer de pulmão e controles (do quartil mais baixo ao mais alto: 20,0%; 20,0%; 24,0%; 36,0% vs. 26,7%; 26,2%; 25,8%; 21,3%; p=0,022). A pontuação no escore SYNTAX foi mais alta em pacientes com câncer do que nos pacientes controle (36,0% vs. 21,3%, p=0,011).O maior quartil do escore demonstrou mais riscos de desenvolver câncer de pulmão em comparação ao quartil mais baixo (OR: 2.250, IC95%: 1.077 a 4.699 ; P -trend= 0,016). Após ajustes, os pacientes no maior quartil do escore SYNTAX tinham mais risco de desenvolver câncer de pulmão (OR: 2.1o49, IC95%: 1.008 a 4.584; P -trend= 0,028). Pacientes com escores SYNTAX alto (> 15) tinham 1.985 mais chances de ter câncer de pulmão (IC95%: 1.105–3.563, P= 0,022). Conclusão A gravidade anatômica da DAC está associada ao risco de câncer de pulmão, o que indica que um rastreamento completo deste tipo de câncer possa ser mais significativo entre pacientes com DAC.

Abstract Background The direct relationship between coronary artery disease (CAD) and lung cancer is not well known. Objective To investigate the association between the anatomical severity of CAD and lung cancer. Methods Three-hundred study patients, including 75 recently diagnosed lung cancer patients and 225 matched non-cancer patients, underwent coronary angiography during hospitalization without previous percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). The SYNTAX score (SXscore) was used to assess the severity of CAD. A high SXscore (SXhigh) grade was defined as SXscore > 15 (the highest quartile of the SXscore). The Cochran-Armitage test for trend was used to assess the distribution of patients’ SXscores. Logistic regression analysis was used to assess the association between the severity of CAD and lung cancer. P-values were set when significance level was 5%. Results The distribution trend of patients’ SXscore by quartiles was different between lung cancer patients and control patients (from the lowest to the highest quartile: 20.0%, 20.0%, 24.0%, 36.0% vs. 26.7%, 26.2%, 25.8%, 21.3%, p=0.022). The SX high rate was higher in lung cancer patients than in control patients (36.0% vs. 21.3%, p=0.011).The highest quartile of the SXscore showed higher risk of lung cancer in comparison to the lowest quartile (OR: 2,250, 95%CI: 1,077 to 4,699 ; P-trend= 0.016). After adjustment, patients in the highest quartile of the SXscore had higher risk of lung cancer (OR: 2,149, 95%CI: 1,008 to 4,584; P-trend= 0.028). Patients with high SXscore (> 15) had 1,985 times more chances of having lung cancer (95%CI: 1,105–3,563, P= 0.022). Conclusions The anatomical severity of CAD is associated with the risk of lung cancer, which indicates that a thorough lung cancer screening may be significant among severe CAD patients.

Abstract We aimed to study level of cardiac troponin T(cTnT) and its possible influence factorsin maintenance hemodialysis (MHD) patients. Blood was obtained from 123 MHD patients before undergoing hemodialysis. Patients with cardiovascular disease (CVD) had higher cTnT levels than those without CVD (0.062 [0.044 - 0.083] ng/mL vs 0.031[0.020 - 0.046] ng/mL, P = 0.002). Patients with diabetes mellitus (DM) had higher cTnT levels than those non-DM (0.061[0.042 - 0.102] ng/mL vs 0.044[0.025 - 0.064] ng/mL, P = 0.003). We found that in all MHD patients, cTnT correlated positively with age(ρ = 0.309, P = 0.001), glycated albumin (ρ = 0.192, P = 0.040), amino-terminal pro-B-natriuretic peptide (NT-proBNP) (ρ = 0.448, P < 0.001), high-sensitive C reactive protein(hsCRP) (ρ = 0.335, P < 0.001), carotid artery intima-media thickness (ρ = 0.315, P = 0.004) and left ventricular mass index(ρ = 0.369, P < 0.001); negatively with pre-albumin(ρ = -0.280, P = 0.002), high density lipoprotein cholesterol(ρ = -0.201, P = 0.047). Age (β = 0.204, P = 0.043), NT-proBNP (β = 0.299, P = 0.010) and left ventricular mass index (β = 0.345, P = 0.003) were independently associated cTnT. Receiver operating characteristic (ROC) curves analysis showed the correlation between cTnT and CVD was more closely than NT-proBNP and hsCRP, the correlation between cTnT and left ventricular hypertrophy was lower than NT-proBNP, and higher than hsCRP. In conclusions, serum cTnT is markedly elevated in MHD patients; Serum cTnT is associated with advanced age, fluid overload, malnutrition, microinflammation, left ventricular hypertrophy and CVD in MHD patients.

Abstract This study aimed to analyze the main components of ethyl acetate extract of Chimonanthus salicifolius (EAECS) and investigate its effect on intestinal mucositis in mice induced by 5-fluorouracil. EAECS was prepared, and its main components were analyzed. Fifty mice were randomly divided into control, model and 3, 6 and 9 g/kg EAECS groups. The latter three groups were intragastrically administrated with 3, 6 and 9 g/kg EAECS for 7 days, respectively. The intestinal mucositis model was established in latter four groups from the 1st to 7th day of administration. Results showed that, the main components in EAECS were rutin, scopolamine, isofraxidin, scoparone, quercetin and kaempferol. After administration, compared with model group, in 9 g/kg EAECS group the body weight was increased; the serum tumor necrosis factor α (TNF-α) and interleukin 6 levels were decreased, and the interleukin 10 level was increased; the intestinal tissue superoxide dismutase level was increased, and the malondialdehyde and myeloperoxidase levels wer decreased; the liver tissue TNF-α level was significantly decreased (all P < 0.05). In conclusion, EAECS has rich flavonoids and coumarins. It can alleviate the intestinal mucositis in mice induced by 5-FU. The mechanism may be related to the anti-inflammatory and antioxidant effects.
