Abstract The current developmental trend is to evaluate the quality of Yongchuan Xiuya tea rapidly. After spectrum pre-processing, near infrared spectroscopy (NIRS) coupled with synergy interval partial least squares (siPLS), principal component analysis (PCA) and back propagation-artificial neural network (BP-ANN) was applied to rapidly and non-destructively predict the quality of Yongchuan Xiuya tea. External Yongchuan Xiuya tea samples were used for the actual application of the proposed model. The best pre-processing method was multiple scattering correction coupled with second derivative, and the characteristic spectral regions selected by siPLS were 4381.5-4755.6 cm-1, 4759.5-5133.6 cm-1, 6266.6-6637.8 cm-1 and 7389.9-7760.2 cm-1. The cumulative contribution rate was 99.05% for the first three principal components of the characteristic spectra regions. The transfer function, root mean square error and determinant coefficient of the best BP-ANN prediction model were the tanh function, 0.384 and 0.977, respectively. The root mean square error and determinant coefficient of the external 10 Yongchuan Xiuya tea samples were 0.406 and 0.969, respectively. These results showed that NIRS combined with BP-ANN algorithm can be used to evaluate the quality of Yongchuan Xiuya tea rapidly and accurately.

ABSTRACT Introduction: The success of frozen embryo transfer cycles depends on a delicate interaction between embryo quality and endometrium. Low pregnancy rates are associated with a thin endometrium. Objective: To evaluate the effect of autologous platelet-rich plasma treatment on patients with thin endometrium. Methods: In 34 patients with thin endometrium (< 7 mm), canceled in the previous frozen embryo transfer cycles, autologous platelet-rich plasma was prepared, from autologous peripheral vein blood; intrauterine infusion was given during hormone replacement therapy in frozen embryo transfer cycles. Frozen embryo transfer was performed when the endometrium thickness reached ≥ 7mm. Results: Six patients canceled the embryo transfer cycle due to endometrium thickness did not reach 7 mm; 28 patients got endometrial thickness ≥ 7 mm and performed frozen embryo transfer. The endometrial thickness was 7.5 ± 0.8 mm, which was significantly thicker than in the previous cycles (5.6 ± 0.79 mm) with p< 0.002, the implantation rate was 23.07 %, and the clinical pregnancy rate was 12/28 (42.8 %). Conclusion: Autologous platelet-rich plasma improves the endometrial thickness and the pregnancy rate outcomes in women with thin endometrium.

RESUMEN Introducción: El éxito de los ciclos de transferencia de embriones congelados depende de una delicada interacción entre la calidad del embrión y el endometrio. Las bajas tasas de embarazo están asociadas con un endometrio delgado. Objetivo: Evaluar el efecto del tratamiento con plasma rico en plaquetas autólogo en pacientes con endometrial delgado. Métodos: En 34 pacientes con endometrio delgado (< 7 mm) canceladas en los ciclos previos de transferencia de embriones congelados, se preparó plasma autólogo rico en plaquetas, a partir de sangre autóloga de venas periféricas; la infusión intrauterina se administró durante la terapia de reemplazo hormonal en los ciclos de transferencia de embriones congelados. La transferencia de embriones congelados se realizó cuando el grosor del endometrio alcanzó ≥ 7 mm. Resultados: En 6s pacientes se canceló el ciclo de transferencia embrionaria debido a que el grosor del endometrio no alcanzó los 7 mm; 28 pacientes obtuvieron un grosor endometrial ≥ 7 mm y realizaron transferencia de embriones congelados. El grosor del endometrio fue de 7,5 ± 0,8 mm, significativamente mayor que en los ciclos anteriores (5,6 ± 0,79 mm) con p< 0,002; la tasa de implantación fue de 23,07 % y la tasa de embarazo clínico fue de 12/28 (42,8 %). Conclusión: El plasma autólogo rico en plaquetas mejora el grosor endometrial y los resultados de la tasa de embarazo en mujeres con endometrio delgado.

This article proposes a posthumanist reading of Joyce Carol Oates's "Poe Posthumous; or, The Light-House," and argues that posthumanism provides human beings with a new way of living. In the story, the narrator comes to the Light-House at Viña de Mar to participate in a scientific experiment. As an "exemplary specimen of Homo sapiens," the narrator endeavours to preserve human knowledge, which symbolises his superiority over nonhuman species. However, on becoming further involved in nature, he gradually abandons his anthropocentric thought, and learns to live with other species. The posthumanist thought finds its full expression in the symbiotic coexistence of multiple species and culminates in the narrator' s cross-species marriage to a female Cyclophagus. The juxtaposition of the decentring of anthropocentrism with the ascent of nonhuman agents highlights the posthumanist coexistence of humans and nonhumans.

Abstract Oxygen glucose deprivation/re-oxygenation (OGD/R)-mediated ischemia of kidney is frequently leads to enhanced apoptosis and amplified inflammatory response. Sappanchalcone (Sap) is a flavonoid compound that extracted from Caesalpinia sappan L. with a range of cell-protective activities. Herein, we primarily reconnoitered the influence of Sap in HK-2 cells under OGD/R treatment. In this research, the consequence revealed that Sap might linked with ischemia of kidney. Besides, Sap lessened OGD/R-mediated HK-2 cell injury by boosting cell viability, inhibiting apoptosis and inflammation. In addition, Sap hindered activation of the TNFRSF1A/NF-kB signaling. Moreover, upregulation of TNFRSF1A diminished the repressive influence of Sap on OGD/R-mediated apoptosis and inflammation. In conclusion, Sap declined the OGD/R-induced HK-2 cell injury by downregulation of TNFRSF1A/NF-kB signaling, thereby offered a theoretical basis for the handling of ischemia of kidney.

ABSTRACT Purpose: We aimed to find the association between screen time (ST)-based sedentary behavior and depression in children and adolescents. Methods: PubMed, Embase, and Web of science database were searched to find eligible studies until April 25, 2021. Data extraction was conducted by two investigators independently, followed by quality assessment for included studies. Odd ration (OR) and 95% confidence intervals (CI) were regarded as effect size index. Heterogeneity test was conducted using Cochran’ s Q test and I2 test. Least squares trend estimation method was used for dose-response meta-analysis. All statistical analyses were conducted using Stata12.0 software. Results: Totally 22 articles containing 197,673 cases were included. The pooled results displayed that there was a significant positive correlation between ST and depression [OR (95%CI) = 1.24 (1.11, 1.38), P < 0.001]. Similar results were observed for watching television (TV), computer use (CU), computer game (CG)/video game (VG) and internet use (IU)/mobile phone (MP) time. Dose-response meta-analysis showed that take 1 hour/day as control, the risk of depression went down and then went up as sedentary time increased for ST (P > 0.05). The risk of depression was significantly increased when TV time beyond 4.5 hours/day (P < 0.05), or CU time beyond 0.5 hours/day (P < 0.05), or CG/VG time beyond 2 hours/day (P < 0.05), or IU/MP time beyond 0.5 hours/day (P < 0.05). Conclusion: ST-based sedentary behavior was associated with the risk of depression in a non-linear dose–response manner for children and adolescents.

Abstract Objective This study aimed to identify the predictors and threshold of failure in neonatal acute respiratory distress syndrome. Methods Newborns with severe acute respiratory distress syndrome aged 0-28 days and gestational age ≥36 weeks were included in the study if their cases were managed with non-extra corporal membrane oxygenation treatments. Patients were divided into two groups according to whether they died before discharge. Predictors of non-extra corporal membrane oxygenation treatment failure were sought, and the threshold of predictors was calculated. Results A total of 103 patients were included in the study. A total of 77 (74.8%) survived hospitalization and were discharged, whereas 26 (25.2%) died. Receiver operating characteristic analysis of oxygen index, pH, base excess, and combinations of these indicators demonstrated the advantage of the combination of oxygen index and base excess over the others variables regarding their predictive ability. The area under the curve for the combination of oxygen index and base excess was 0.865. When the cut-off values of oxygen index and base excess were 30.0 and −7.4, respectively, the sensitivity and specificity for predicting death were 77.0% and 84.0%, respectively. The model with base excess added a net reclassification improvement of 0.090 to the model without base excess. Conclusion The combination of oxygen index and base excess can be used as a predictor of outcomes in neonates receiving non-extra corporal membrane oxygenation treatment for acute respiratory distress syndrome. In neonates with acute respiratory distress syndrome, if oxygen index >30 and base excess <−7.4, non-extra corporal membrane oxygenation therapy is likely to lead to death.

Abstract Background: Leaves of the natural plant lotus are used in traditional Chinese medicine and tea production. They are rich in flavonoids. Methods: In this study, lotus leaf flavonoids (LLF) were applied to human lung cancer A549 cells and human small cell lung cancer cells H446 in vitro to verify the effect of LLF on apoptosis in these cells through the ROS/p38 MAPK pathway. Results: LLF had no toxic effect on normal cells at concentrations up to 500 μg/mL, but could significantly inhibit the proliferation of A549 cells and H446 cells. Flow cytometry showed that LLF could induce growth in A549 cells. We also found that LLF could increase ROS and MDA levels, and decrease SOD activity in A549 cells. Furthermore, qRT-PCR and western blot analyses showed that LLF could upregulate the expression of p38 MAPK (p-p38 MAPK), caspase-3, caspase-9, cleaved caspase-3, cleaved caspase-9 and Bax and downregulate the expression of Cu/Zn SOD, CAT, Nrf2, NQO1, HO-1, and Bcl-2 in A549 cells. Results of HPLC showed that LLF mainly contain five active substances: kaemp-feritrin, hyperoside, astragalin, phloridzin, and quercetin. The apoptosis-inducing effect of LLF on A549 cells came from these naturally active compounds. Conclusions: We have shown in this study that LLF is a bioactive substance that can induce apoptosis in A549 cells in vitro, and merits further research and development.

RESUMO OBJETIVO: Investigar o efeito protetor e o mecanismo da dexmedetomidina (Dex) na lesão perioperativa do miocárdio em doentes com dissecação aórtica Tipo A de Stanford (AD). MÉTODOS: Oitenta e seis pacientes com o Tipo A de Stanford foram aleatoriamente divididos em Dex e grupos de controle, 43 casos em cada grupo. Durante a cirurgia, o grupo de controle recebeu a anestesia de rotina, e o grupo Dex recebeu tratamento Dex baseado na anestesia de rotina. A frequência cardíaca (AR) e a pressão arterial média (MAP) foram registradas no momento anterior ao Dex carregar (t0), 10 minutos após o Dex carregar (t1), incisão cutânea (t2), serragem de esterno (t3), antes do bypass cardiopulmonar (t4), extubação (t5) e fim da cirurgia (t6). Os índices de sangue foram determinados no momento antes da indução da anestesia (T0) e no pós-operatório 12 horas (T1), 24 horas (T2), 48 horas (T3) e 72 horas (T4). RESULTADOS: Em T2 e t3, o RH e o MAP do grupo Dex foram inferiores ao grupo de controle (p<0,05). Em comparação com o grupo de controle, no grupo Dex em T1, T2 e T3, os níveis séricos de creatina quinase-MB, troponina-I, proteína C-reativa e necrose do fator-α do tumor diminuíram, o nível interleucina-10 aumentou, o desalinhamento total do superóxido sérico e a capacidade antioxidante total aumentaram e os níveis de mielopeperóxido e malondialdeído diminuíram (todos p<0,05). CONCLUSÃO: O tratamento com Dex pode aliviar a lesão do miocárdio perioperativo em doentes com o Tipo A de Stanford por resistência à resposta inflamatória e ao estresse oxidativo.

SUMMARY OBJECTIVE: To investigate the protective effect and mechanism of dexmedetomidine (Dex) on perioperative myocardial injury in patients with Stanford type-A aortic dissection (AD). METHODS: Eighty-six patients with Stanford type-A AD were randomly divided into Dex and control groups, with 43 cases in each group. During the surgery, the control group received the routine anesthesia, and the Dex group received Dex treatment based on routine anesthesia. The heart rate (HR) and mean arterial pressure (MAP) were recorded before Dex loading (t0), 10 min after Dex loading (t1), at the skin incision (t2), sternum sawing (t3), before cardiopulmonary bypass (t4), at the extubation (t5), and at end of surgery (t6). The blood indexes were determined before anesthesia induction (T0) and postoperatively after 12h (T1), 24h (T2), 48h (T3), and 72h (T4). RESULTS: At t2 and t3, the HR and MAP in the Dex group were lower than in the control group (P < 0.05). Compared with the control group, in the Dex group at T1, T2, and T3, the serum creatine kinase-MB, cardiac troponin-I, C-reactive protein, and tumor necrosis factor-α levels were decreased, and the interleukin-10 level, the serum total superoxide dismutase, and total anti-oxidant capability increased, while the myeloperoxidase and malondialdehyde levels decreased (all P < 0.05). CONCLUSIONS: Dex treatment may alleviate perioperative myocardial injury in patients with Stanford type-A AD by resisting inflammatory response and oxidative stress.

ABSTRACT Objective: The objective of the study was to develop an association between clinicopathologic and sonographic features of patients with papillary thyroid microcarcinoma and the prevalence of lymph node metastasis. Subjects and methods: Clinicopathologic and sonographic features of 415 patients of papillary thyroid microcarcinoma with (n = 102) or without (n = 313) lymph node metastasis were retrospectively reviewed. The thickness of the lymph node ≥ 6 mm with intra-lymph nodal occupying lesions considered lymph node metastasis. Also, it was considered metastasis if lymph node perfusion or blood flow defect was found with any thickness size. Univariate following multivariate analysis was performed for the prediction of sonographic features and clinicopathologic factors for the prevalence of lymph node metastasis. Results: Male gender ( p = 0.041), age < 45 years ( p = 0.042), preoperative calcitonin > 65 pg/ mL ( p = 0.039), nodule size > 5 mm in diameter ( p = 0.038), bilaterality ( p = 0.038), tumor capsular invasion ( p = 0.048), cystic change ( p = 0.047), and hyper vascularity ( p = 0.049) of thyroid nodules were associated with lymph node metastasis. Also, thyroid nodules 5 mm and more in diameter may have high aggressiveness. Conclusion: These data helped the surgeon for individualized treatment in thyroid carcinoma and avoid unnecessary prophylactic surgery of the lymph node.

CONCLUSÕES A técnica de imagem da hidrografia por RM pode ser aplicada à avaliação pré-operatória do implante coclear, que pode fornecer informações anatômicas precisas e confiáveis sobre o labirinto membranoso interno e os nervos no canal acústico interno, além de uma base exata para o diagnóstico da fibrose coclear e do desenvolvimento do nervo. Isso tem um significado orientador para a seleção de esquemas de tratamento.

SUMMARY OBJECTIVE This study aims to investigate the application value of magnetic resonance (MR) hydrography of the inner ear in cochlear implantation. METHODS 146 patients were enrolled. MR hydrography and spiral CT examinations for the intracranial auditory canal were performed before surgery, and all imaging results were statistically analyzed in order to explore the application value of MR hydrography of the inner ear in cochlear implantation. RESULTS 146 patients (292 ears) were examined. Among these patients, 13 were diagnosed with abnormal vestibular aqueducts (20 ears) by MR hydrography, while five were diagnosed with this disease by CT; 15 patients were diagnosed with inner ear malformation (19 ears) by MR hydrography, while 11 were diagnosed by CT (four were misdiagnosed); five patients were diagnosed with internal acoustic canal stenosis (eight ears) by MR hydrography, while two were diagnosed by CT (three were misdiagnosed); and four patients were diagnosed with cochlear fibrosis (five ears) by MR hydrography, while four were diagnosed by CT (four ears). The correct rate of diagnosis was 77.40% (113/146) based on CT, while the rate was 93.84% (137/146) based on MR hydrography. CONCLUSIONS MR hydrography imaging technique can be applied to the preoperative evaluation of cochlear implantation, providing accurate and reliable anatomic information on the inner membranous labyrinth and nerves in the internal acoustic canal and an accurate basis for the diagnosis of cochlear fibrosis and nerve development. This has a guiding significance for the selection of treatment schemes.

Abstract: This paper analyzes the interaction between two political economy decisions by a government: whether to privatize a public firm and what environmental policy to choose (an environmental tax or an emission standard). We find that when market competition is weak the government does not privatize the public firm and sets an environmental tax. When it is intermediate the public firm is not privatized and the government sets an environmental standard. Finally, when market competition is strong the government privatizes the public firm and is indifferent between a tax and a standard.

Resumen: Este artículo analiza la interacción entre dos decisiones de economía política que tiene que tomar un gobierno: si privatizar una empresa pública y qué política ambiental elegir (un impuesto medioambiental o un estándar de emisiones). Encontramos que cuando la competencia de las empresas en el mercado es débil, el gobierno no privatiza la empresa pública y establece un impuesto medioambiental. Cuando es intermedia, la empresa pública no se privatiza y el gobierno establece un estándar medioambiental. Finalmente, cuando la competencia en el mercado es fuerte, el gobierno privatiza la empresa pública y está indiferente entre un impuesto y un estándar.

SUMMARY: The suprascapular artery (SSA) has been identified to be of clinical relevance to clavicular fracture, suprascapular neuropathy and surgical intervention of shoulder. Thus its origin and course have been intensively studied. In this case, we found a unilateral variation of the suprascapular artery, originating from the 1st segment of axillary artery, and sequentially penetrating the upper trunk of brachial plexus, passing through the suprascapular notch under the superior transverse scapular ligament. This case will be helpful to clinical management in cervical and shoulder region.

Este caso será útil para el manejo clínico en la región cervical y del hombro.

RESUMO OBJETIVO Estudar os fatores que afetam a regeneração hepática após hepatectomia. MÉTODOS A capacidade de regeneração hepática de 117 pacientes foi analisada com a tecnologia de reconstituição 3D e foram estudados os fatores relacionados. RESULTADOS Não houve diferença estatística significante entre o volume de ressecção hepática simulada e a ressecção atual. Todos os fígados apresentaram diferentes graus de regeneração após cirurgia. Idade, gênero e indicadores sanguíneos não tiveram impacto na regeneração hepática, enquanto que tempo de cirurgia, perda sanguínea intraoperatória, tempo de bloqueio do fluxo sanguíneo e diferentes formas de ressecção mostraram impacto significante na regeneração do órgão. Além disso, condições patológicas dos pacientes, incluindo hepatite e fibrose hepática, tiveram impacto significante na regeneração hepática. CONCLUSÃO O modelo de reconstituição 3D é um bom modelo para calcular o volume do fígado. Idade, gênero, indicadores sanguíneos e bioquímicos não tiveram impacto na regeneração hepática, mas indicadores operatórios e condição patológica dos pacientes mostraram influência na regeneração do órgão.

SUMMARY OBJECTIVE To study factors affecting the liver regeneration after hepatectomy METHODS With 3D reconstitution technology, liver regeneration ability of 117 patients was analysed, and relative factors were studied. RESULTS There was no statistically difference between the volume of simulated liver resection and the actual liver resection. All livers had different degrees of regeneration after surgery. Age, gender and blood indicators had no impact on liver regeneration, while surgery time, intraoperative blood loss, blood flow blocking time and different ways of liver resection had a significant impact on liver regeneration; In addition, the patients’ own pathological status, including, hepatitis and liver fibrosis all had a significant impact on liver regeneration. CONCLUSION 3D reconstitution model is a good model to calculate liver volume. Age, gender, blood indicators and biochemistry indicators have no impact on liver regeneration, but surgery indicators and patients’ own pathological status have influence on liver regeneration.

Abstract Biofertilizer Ning shield was composed of different strains of plant growth promotion bacteria. In this study, the plant growth promotion and root-knot nematode disease control potential on Trichosanthes kirilowii in the field were evaluated. The application of Ning shield significantly reduced the diseases severity caused by Meloidogyne incognita, the biocontrol efficacy could reached up to 51.08%. Ning shield could also promote the growth of T. kirilowii in the field by increasing seedling emergence, height and the root weight. The results showed that the Ning shield could enhance the production yield up to 36.26%. Ning shield could also promote the plant growth by increasing the contents of available nitrogen, phosphorus, potassium and organic matter, and increasing the contents of leaf chlorophyll and carotenoid pigment. Moreover, Ning shield could efficiently enhance the medicinal compositions of Trichosanthes, referring to the polysaccharides and trichosanthin. Therefore, Ning shield is a promising biofertilizer, which can offer beneficial effects to T. kirilowii growers, including the plant growth promotion, the biological control of root-knot disease and enhancement of the yield and the medicinal quality.
