ABSTRACT Objective: The optimal target for blood glucose concentration in critically ill patients is unclear. We will perform a systematic review and meta-analysis with aggregated and individual patient data from randomized controlled trials, comparing intensive glucose control with liberal glucose control in critically ill adults. Data sources: MEDLINE®, Embase, the Cochrane Central Register of Clinical Trials, and clinical trials registries (World Health Organization, clinical trials.gov). The authors of eligible trials will be invited to provide individual patient data. Published trial-level data from eligible trials that are not at high risk of bias will be included in an aggregated data meta-analysis if individual patient data are not available. Methods: Inclusion criteria: randomized controlled trials that recruited adult patients, targeting a blood glucose of ≤ 120mg/dL (≤ 6.6mmol/L) compared to a higher blood glucose concentration target using intravenous insulin in both groups. Excluded studies: those with an upper limit blood glucose target in the intervention group of > 120mg/dL (> 6.6mmol/L), or where intensive glucose control was only performed in the intraoperative period, and those where loss to follow-up exceeded 10% by hospital discharge. Primary endpoint: In-hospital mortality during index hospital admission. Secondary endpoints: mortality and survival at other timepoints, duration of invasive mechanical ventilation, vasoactive agents, and renal replacement therapy. A random effect Bayesian meta-analysis and hierarchical Bayesian models for individual patient data will be used. Discussion: This systematic review with aggregate and individual patient data will address the clinical question, ‘what is the best blood glucose target for critically ill patients overall?’ Protocol version 0.4 - 06/26/2023 PROSPERO registration: CRD42021278869

RESUMO Objetivo: Não está claro qual é a meta ideal de concentração de glicose no sangue em pacientes em estado grave.

ABSTRACT The original two-order separating sieve has a good potato-soil separating ability, but it causes significant damage to potatoes while ensuring a high potato detection rate, which in turn affects the working effectiveness of the potato digger. Thus, it is necessary to improve the design of the original swing separation sieve with a two-order sieve surface to one with a three-order sieve surface to solve the contradiction between the potato detection and potato damage. On this basis, the movement characteristics of potatoes and the separation performance of the new sieve were experimentally investigated. The experiment was conducted in a test field in Wuchuan County using a completely randomized design in a single-factor scheme with three factors and five levels, with five crank speeds (140, 150, 180, 210 and 225 rpm), five machine forward speeds (1.41, 1.51, 1.70, 1.89 and 2.21 km h-1) and five boom-connecting rod length combinations (250-350-1,030, 250-370-1,040, 270-370-1,050, 290-370-1,060 and 310-370-1,070 mm). Each experiment was repeated three times at each level, and the average value was taken as the final result. The experimental results demonstrate that the new three-order separation sieve can ensure a high potato detection rate while maintaining a low potato skin breakage rate.

RESUMO A peneira de separação de duas ordens original tem uma boa capacidade de separação batata-solo, mas causa danos significativos às batatas ao mesmo tempo em que garante uma alta taxa de evidência de batatas, o que, por sua vez, afeta a eficácia do trabalho da escavadeira de batatas. Assim, o estudo teve como objetivo aprimorar a peneira de separação de balanço original com uma superfície de peneira de duas ordens para uma nova peneira de separação com uma superfície de peneira de três ordens para resolver a contradição entre a taxa obvia de batatas e os danos às batatas na operação da peneira original. Com base nisso, as características de movimentação das batatas e o desempenho de separação da nova peneira foram investigados experimentalmente no campo. O experimento foi conduzido em um campo de teste no Condado de Wuchuan, utilizando um delineamento completamente aleatório em um esquema de fator único com três fatores e cinco níveis, com cinco velocidades de manivela (140, 150, 180, 210 e 225 rpm), cinco velocidades de avanço da máquina (1,41, 1,51, 1,70, 1,89 e 2,21 km h-1) e cinco combinações de comprimento da haste de ligação do braço (250-350-1.030, 250-370-1.040, 270-370-1.050, 290-370-1.060 e 310-370-1.070 mm). Cada experimento foi repetido três vezes em cada nível, e o valor médio foi considerado como o resultado final. Os resultados experimentais demonstram que a nova peneira de separação de três ordens pode garantir uma alta taxa de detecção de batatas enquanto mantém uma baixa taxa de danos à casca das batatas.

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: The privacy problem of facial recognition technology is that commercial companies obtain people’s facial information without the consent of individuals and use facial information to infringe on the privacy of individuals. The importance of human privacy in facial recognition technology is reflected through facial ethics, which requires others to perform corresponding obligations to individuals, such as oral care. Through the analysis of the privacy issues of facial recognition technology, it is found that the two elements of “without personal informed” and “without personal consent” together form the basis for commercial companies to violate personal privacy. The principle of informed consent includes the principle of informed and the principle of consent, which is derived from the principle of informed consent in medical ethics. This paper improves the principles of informed consent in medicine and ethics to better address facial recognition privacy issues.

Resumen: El problema de la privacidad en la tecnología de reconocimiento facial es que las empresas comerciales obtienen información facial de las personas sin el consentimiento de éstas y utilizan la información facial para vulnerar la privacidad de las personas. La importancia de la privacidad de las personas en la tecnología de reconocimiento facial se refleja a través de la ética facial, que exige que otros cumplan las obligaciones correspondientes con los individuos, como el cuidado bucal. A través del análisis de los problemas de privacidad de la tecnología de reconocimiento facial se descubre que los dos elementos de “sin información personal” y “sin consentimiento personal” juntos forman la base para que las empresas comerciales violen la privacidad personal. El principio de consentimiento informado incluye el de información y el de consentimiento, que se deriva del principio de consentimiento informado de la ética médica. Este artículo mejora los principios del consentimiento informado en medicina y ética para abordar mejor los problemas de privacidad del reconocimiento facial.

Resumo: A questão da privacidade na tecnologia de reconhecimento facial é que as companhias comerciais obtém informações faciais das pessoas sem seu consentimento e usam informação facial para infringir sua privacidade. A importância da privacidade humana na tecnologia de reconhecimento facial é refletida através da ética facial, que exige que se cumpram obrigações correspondentes para com os indivíduos, da mesma forma como com cuidados orais. Através da análise de aspectos de privacidade na tecnologia de reconhecimento facial, encontrou-se que os dois elementos “sem informação pessoal” e “sem consentimento pessoal” juntos, formam a base para companhias comerciais violarem a privacidade pessoal. O princípio do consentimento informado inclui o princípio de informação e o princípio de consentimento, os quais derivam do princípio do consentimento informado em ética médica. Esse artigo melhora os princípios do consentimento informado em medicina e ética para melhor incluir aspectos de privacidade no reconhecimento facial.

SUMMARY: At present, the anatomical relationship the mid-portion of popliteus tendon complex (PTC) and the surrounding tissues is still unclear, especially its relationship to the posterior cruciate ligament (PCL). It affected the anatomical reconstruction of the posterolateral complex (PLC) injury. A total of 30 cases of the adult human knee joint fixed with formalin were used. Sagittal sections were made in 14 knee joints by the P45 plastination technique and dissection of 16 cases of knee joints. The P45 section revealed that the popliteus muscle fascia ran superiorly over the posterior edge of the tibial intercondylar eminence, and turned forward to be integrated into the PCL. Laterally, near the posterior edge of the lateral tibial plateau, the popliteus tendon penetrates through the articular capsule (AC), where two dense fibrous bundles were given off upwards by the popliteus tendon: one was the ventral fiber bundle, which ran superiorly over the posterior edge of the tibial plateau and then moved forwards to connect with the lateral meniscus; the dorsal fibers bundle ascended directly and participated in the AC. Meanwhile, the popliteus muscle dissection showed that at the posterior edge of the platform of the lateral condyle of the tibia, at the tendon-muscle transition, the PTC and AC were anchored to PCL.

RESUMEN: En la actualidad, la relación anatómica entre la porción media del complejo tendinoso poplíteo (CTP) y los tejidos circundantes aún no está clara, especialmente su relación con el ligamento cruzado posterior (LCP). Esto afecta la reconstrucción anatómica de la lesión del complejo posterolateral (LCP). Se utilizaron un total de 30 casos de articulaciones de rodillas humanas de individuos adultos fijadas con formalina. Se realizaron cortes sagitales en 14 articulaciones de rodilla mediante la técnica de plastinación P45 y disección de 16 casos de articulaciones de rodilla. La sección P45 reveló que la fascia del músculo poplíteo discurría superiormente sobre el margen posterior de la eminencia intercondílea tibial y giraba hacia delante para integrarse en el LCP. Lateralmente, cerca del margen posterior de la platillo tibial lateral, el tendón poplíteo penetra a través de la cápsula articular (CA), donde el tendón poplíteo desprendió hacia arriba dos haces fibrosos densos: uno era el haz de fibras ventral, que corría superiormente sobre el margen posterior de la meseta tibial y luego se movió hacia adelante para conectar con el menisco lateral; el haz de fibras dorsales ascendía directamente y participaba en la CA. Por su parte, la disección del músculo poplíteo mostró que en el margen posterior del platillo del cóndilo lateral de la tibia, en la transición tendón-músculo, el CTP y el AC estaban anclados al LCP.

Abstract Objective MicroRNA-29a-3p has been reported in a variety of cancers, but its role in hypopharyngeal cancer remains unclear. This study was to determine the role of microRNA-29a-3p in the occurrence and development of hypopharyngeal cancer. Methods 40 patients with hypopharyngeal cancer who underwent surgery in the Affiliated Hospital of Jining Medical University from April 2013 to November 2017 were selected for this study. The cancer tissue samples of the patients were collected, and the patients were followed up for three years. The expression of microRNA-29a-3p in tissue samples was detected by in situ hybridization with fluorescent probe, and the relationships among microRNA-29a-3p and clinicopathological factors, postoperative recurrent-metastasis, survival time were studied. Immunohistochemical was used to detect the expression of Ki67 and E-cadherin in tissue samples. Results Combined with HE staining results showed that microRNA-29a-3p expression was relatively high in non-cancer tissue cells (red blood cells and fibroblasts in tumor interstitial vessels), but was relatively low in cancer tissue and cells. According to the follow-up data of 40 patients with hypopharyngeal cancer, tumor size, T-stage, tumor differentiation, postoperative recurrent-metastasis of hypopharyngeal cancer patients were significantly negatively correlated with microRNA-29a-3p (p< 0.05). Immunohistochemica results further confirmed that microRNA-29a-3p was negatively correlated with the expression of Ki67 and E-cadherin. The survival time of patients positively related with microRNA-29a-3p expression (p< 0.05). Moreover, ROC curve analysis showed that the area under the curve of the combined detection of miRNA-29a-3p+Ki67+E-cadherin was larger than that of the single detection of the three indexes. Conclusions The expression of microRNA-29a-3p is closely related to the occurrence, development and prognosis of hypopharyngeal cancer, and it affects the proliferation and invasion. This indicates that microRNA-29a-3p serves as a therapeutic target for the occurrence and development of hypopharyngeal cancer. The evidence of study designs of this study is IV using “Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence”.

ABSTRACT Introduction: Core strength training focuses mainly on the muscle group and neuromuscular system of the central area of the human body to gain strength and stability for complex movements. Studies have reported the effect of core training on high-capacity athletes, but there is still a gap regarding the impacts on physical capacity in running athletes. Objective: To study the effects of strength training on athletes’ core and the direct impacts on running quality. Methods: Athletes of the men’s running team at the athletic training center of the Institute of Physical Education were core strength trained for 10 to 12 weeks. After the period, physical tests, according to predetermined protocols. The data were compared before, after the intervention, and after statistical treatment, and the findings were discussed according to the scientific literature. Results: After 12 weeks of training, among the five sports skills, there was only a significant difference before and after training of body lateral flexion (right side) (P<0.05), and there was no significant difference before and after training of the other four sport skills (P > 0.05). Conclusions: Through the static and dynamic exercises of core strength training, we can effectively improve the proprioception intervention in body movement so that runners can more accurately control their joints and muscles, ensuring movement and postural accuracy. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Abstract Voriconazole increases tacrolimus blood concentration significantly when coadministrated. The recommendation of reducing tacrolimus to 1/3 in voriconazole package insert seems not to be satisfactory in clinical practice. In vitro studies demonstrated that the magnitude of inhibition depends on the concentration of voriconazole, while voriconazole exposure is determined by the genotype status of CYP2C19. CYP2C19 gene polymorphism challenges the management of drug-drug interactions(DDIs) between voriconazole and tacrolimus. This work aimed to predict the impact of CYP2C19 polymorphism on the DDIs by using physiologically based pharmacokinetics (PBPK) models. The precision of the developed voriconazole and tacrolimus models was reasonable by evaluating the pharmacokinetic parameters fold error, such as AUC0-24, Cmax and tmax. Voriconazole increased tacrolimus concentration immediately in all population. The simulated duration of DDIs disappearance after voriconazole withdrawal were 146h, 90h and 66h in poor metabolizers (PMs), intermediate metabolizers (IMs) and extensive metabolizers(EMs), respectively. The developed and optimized PBPK models in this study can be applied to assit the dose adjustment for tacrolimus with and without voriconazole.

This work presented a new PEG modified calix[4]arene stationary phase (C4A-PEG-2PTSC) for gas chromatographic (GC) separations. The statically coated C4A-PEG-2PTSC column exhibited moderate polarity and column efficiency of 2224 plates m-1 determined by 1-octanol at 120 oC. The results showed that the C4A-PEG-2PTSC column exhibited the good separation performance for various types of analytes containing halogenated benzenes, benzaldehydes, phenols, alcohols, anilines isomers and showed the different retention behavior with the comparative columns. Importantly, it showed the better separation capacity of toluidine and xylidine isomers than commercial HP-35 column. Moreover, it was applied in practical sample analysis to detect the content of isomer impurities. This work exhibited the good application potential of C4A-PEG-2PTSC stationary phase in GC analyses.

Abstract Background: The accuracy of diagnosis and the safety of treatment in colonoscopy depends largely on the quality of bowel cleansing. This study aimed to compare the efficacy and adverse reactions of Polyethylene Glycol (PEG) combined with lactulose with that of PEG alone in bowel preparation before colonoscopy. Methods: The authors searched a number of databases including EMBASE, MEDLINE, Cochrane Library, and China Academic Journals Full-text Database. The authors screened according to literature inclusion and exclusion criteria, assessed the quality of the included literature, and extracted the data. The meta-analysis of included literature used RevMan 5.3 and Stata 14.0 software. Results: A total of 18 studies, including 2274 patients, were enrolled. The meta-analysis showed that PEG combined with lactulose had a better efficacy (OR = 3.87, 95% CI 3.07‒4.87, p = 0.000, and I2 = 36.2% in the efficiency group; WMD = 0.86, 95% CI 0.69‒1.03, p = 0.032 and I2 = 0% in the BBPS score group) in bowel preparation for patients with or without constipation. Moreover, PEG combined with lactulose had fewer adverse reactions, including abdominal pain (OR = 1.42, 95% CI 0.94‒2.14, p = 0.094), nausea (OR = 1.60, 95% CI 1.13‒2.28, p = 0.009) and vomiting (OR = 1.77, 95% CI 1.14‒2.74, p = 0.011), than PEG alone. No significant reduction in the incidence of abdominal distention was observed. Conclusion: PEG combined with lactulose may be a better choice for bowel preparation before colonoscopy compared with PEG alone.

Abstract Objectives: The incidence of cerebellar Glioblastoma Multiforme (cGBM) is rare. Database like TCGA have not distinguish cGBM from GBM, our knowledge on cGBM gene expression characteristics is limited. The expression status of Oligodendrocyte Lineage Transcription factor 2 (OLIG2) and its clinical significance in cGBM is still unclear. Methods: The clinical data and tissue specimens of 73 cGBM patients were retrospectively studied. The association between OLIG2 expression level and the demographic characteristics of cGBM patients was identified by the Chi-Square test. The survival curves were drawn by Kaplan-Meier analysis. The independent prognostic factors was calculated according to Cox regression analysis. Results: The OLIG2 high expression was observed in about 57.5% (42/73) of the cGBM patients. Patients with high OLIG2 expression levels had a higher alive ratio at the end of follow-up (alive ratio: 70.6% vs. 29.4%, p = 0.04). The median survival time was 21 months and 13 months for high and low expression of OLIG2 (p < 0 .05). Univariate analysis and Multivariate analysis indicated that EOR (HR = 3.89, 95% CI 1.23−12.26, p = 0.02), low OLIG2 expression (HR = 5.26, 95% CI 1.13−24.59, p = 0.04), and without adjuvant therapy (HR = 4.95, 95% CI 1.22−20.00, p = 0.03) were independent risk factors for the OS of cGBM patients. Conclusion: High expression level of OLIG2 could be used as an independent favorable prognosis indicator in cGBM patients and be recognized as a characteristic biomarker of cGBM.

Pilot trials have suggested that repetitive transcranial magnetic stimulation (rTMS) may reduce limb spasticity in multiple sclerosis (MS). We carried out the current meta-analysis to synthesize currently available evidence regarding such correlation. Up to November 2022, five international electronic databases (Cochrane CENTRAL, PubMed, Embase, Web of Science, and CINAHL) and four Chinese electronic databases (CBM, CNKI, WanFang Data, and VIP) were systematically searched to identify randomized trials comparing active rTMS and sham stimulation in patients with MS-related spasticity. Two reviewers independently selected studies and extracted data on study design, quality, clinical outcomes, and time points measured. The primary outcome was clinical spasticity relief after intervention. Secondary outcomes included spasticity at the follow-up visit 2 weeks later and post-treatment fatigue. Of 831 titles found, we included 8 studies (181 participants) in the quantitative analysis. Pooled analyses showed that rTMS therapy was associated with significant spasticity relief in the early post-intervention period [standardized mean differences (SMD): -0.67; 95%CI: -1.12 to -0.21], but there was insufficient evidence for rTMS in reducing spasticity at the follow-up visit 2 weeks later (SMD: -0.17; 95%CI: -0.52 to 0.17) and fatigue (SMD: -0.26; 95%CI: -0.84 to 0.31). This evidence supports the recommendations to treat MS-related spasticity with rTMS, but underlines the need for further large randomized trials.

ABSTRACT Purpose: Oxidative stress and apoptosis contribute to the pathological basis of doxorubicin (DOX)-induced cardiotoxicity. Columbianadin (CBN) is one of the main bioactive constituents isolated from the root of Angelica pubescens. Herein, we intended to explore the potential role and molecular basis of CBN in DOX-induced cardiotoxicity. Methods: C57BL/6 mice were subjected to DOX (15 mg/kg/day, i.p.) to generate DOX-induced cardiotoxicity. CBN (10 mg/kg/day, i.p.) was administered for four week following DOX injection. Results: DOX administered markedly dampened cardiac function, increased cardiac injury, excessive reactive oxygen species (ROS) production, and cardiomyocyte loss. These alterations induced by DOX significantly alleviated by CBN treatment. Mechanistically, our results demonstrated that the CBN exerts cardioprotection role against DOX by up-regulating silent information regulator 1 (Sirt1) and decreasing acetylation of forkhead box O1 (FOXO1). Moreover, Sirt1 inhibition with Ex-527 significantly blunt the beneficial effect of CBN on DOX-induced cardiotoxicity, including cardiac dysfunction, ROS, and apoptosis. Conclusion: Collectively, CBN attenuated oxidative stress and cardiomyocyte apoptosis in DOX-induced cardiotoxicity through maintaining Sirt1/FOXO1 signaling pathway. Our results demonstrated that CBN might be used to treat DOX-related cardiotoxicity.

Abstract Compound Danshen Dripping Pills (CDDPs) have been used in clinical treatment to protect the heart from ischemia/reperfusion (IR) injury for many years. However, the underlying mechanism implicated in the protective effects remains to be explored. Here, we determined the effects of CDDPs in Sprague-Dawley rats with the IR model. Cardiac function in vivo was assessed by echocardiography. Transmission electron microscopy, histological and immunohistochemical techniques, Western blotting and recombinant adeno-associated virus 9 transfection were used to illustrate the effects of CDDPs on IR and autophagy. Our results showed that pretreatment with CDDPs decreased the level of serum myocardial enzymes and infarct size in rats after IR. Apoptosis evaluation showed that CDDPs significantly ameliorated the cardiac apoptosis level after IR. Meanwhile, CDDPs pretreatment increased myocardial autophagic flux, with upregulation of LC3B, downregulation of p62, and increased autophagosomes and autolysosomes. Moreover, the autophagic flux inhibitor chloroquine could increase IR injury, while CDDPs could partially reverse the effects. Furthermore, our results showed that the activation of AMPK/mTOR was involved in the cardioprotective effect exerted by CDDPs. Herein, we suggest that CDDPs partially protect the heart from IR injury by enhancing autophagic flux through the activation of AMPK/mTOR.
