ObjectiveThis study aims to systematically review the marketed traditional Chinese patent medicines for treating chronic gastritis （CG） in China. By analyzing their variety characteristics and prescription patterns， it seeks to provide references for clinical syndrome differentiation-based drug selection， treatment method optimization， and the design of high-quality clinical research. MethodsInformation on marketed traditional Chinese patent medicines for treating CG was collected. Microsoft Excel software was used to collate and statistically analyze representative drugs for each pathological stage， market status， syndrome types， and other contents. The Ancient and Modern Medical Case Cloud Platform （V2.3.9） was employed to analyze the formula composition patterns of standardized prescriptions. ResultsA total of 141 marketed traditional Chinese patent medicines for treating CG in China were included. Based on the disease's pathological progression， they can be classified into drugs for non-atrophic gastritis， atrophic gastritis， and precancerous lesions. Post-marketing research reveals that relevant evaluation is only conducted on 17 drugs， of which 2 involve pharmacoeconomic studies and 14 possess standardized evidence-based evidence. The primary dosage forms were capsules， granules， and tablets. From the 100 prescriptions screened according to inclusion/exclusion criteria， the varieties indicated for the stomach collateral stasis syndrome in atrophic gastritis accounted for the highest proportion. The main efficacy distributions were clearing heat， detoxifying， and relieving pain by promoting Qi circulation. Core drugs included Glycyrrhizae Radix et Rhizome， Paeoniae Radix Alba， and Aucklandiae Radix. Medicinal properties were predominantly warm and neutral. Flavors were mainly bitter， pungent， and sweet. The drugs primarily entered the spleen and stomach meridians. Analysis of the package inserts reveals that 67 products list "contraindications"， 110 include "precautions"， and 23 explicitly state "adverse reactions". ConclusionTraditional Chinese patent medicines for treating CG hold unique value in clinical practice. However， currently there are challenges such as insufficient clarity in syndrome type descriptions within package inserts and a relative lack of high-level evidence-based medical evidence， as well as pharmacoeconomic evaluations. Future efforts should focus on addressing these shortcomings by advancing research on syndrome characteristics and medication patterns based on syndrome differentiation， systematically conducting pharmacoeconomic evaluations， strengthening the accumulation of high-level evidence-based evidence， and， on this basis， improving patient medication adherence. This will comprehensively enhance the clinical application value and scientific connotation of this category of drugs.

BACKGROUND: The sirtuin family is well recognized for its crucial involvement in various cellular processes. Nevertheless, studies on its role in the human endometrium are limited. This study aimed to explore the expression and localization of the sirtuin family in the human endometrium, focusing on sirtuin 3 (SIRT3) and its potential role in the oxidative imbalance of the endometrium in polycystic ovary syndrome (PCOS). METHODS: Endometrial specimens were collected from both patients with PCOS and controls undergoing hysteroscopy at the Center for Reproductive Medicine, Peking University Third Hospital, from July to August 2015 and used for cell culture. The protective effects of SIRT3 were investigated, and the mechanism of SIRT3 in improving endometrial receptivity of patients with PCOS was determined using various techniques, including cellular bioenergetic analysis, small interfering ribonucleic acid (siRNA) silencing, real-time quantitative polymerase chain reaction, Western blot, immunofluorescence, immunohistochemistry, and flow cytometry analysis. RESULTS: The sirtuin family was widely expressed in the human endometrium, with SIRT3 showing a significant increase in expression in patients with PCOS compared with controls ( P <0.05), as confirmed by protein and gene assays. Concurrently, endometrial antioxidant levels were elevated, while mitochondrial respiratory capacity was reduced, in patients with PCOS ( P <0.05). An endometrial oxidative stress (OS) model revealed that the downregulation of SIRT3 impaired the growth and proliferation status of endometrial cells and reduced their receptivity to day 4 mouse embryos. The results suggested that SIRT3 might be crucial in maintaining normal cellular state by regulating antioxidants, cell proliferation, and apoptosis, thereby contributing to enhanced endometrial receptivity. CONCLUSIONS Our findings proposed a significant role of SIRT3 in improving endometrial receptivity in patients with PCOS by alleviating OS and regulating the balance between cell proliferation and apoptosis. Therefore, SIRT3 could be a promising target for predicting and improving endometrial receptivity in this patient population.

BACKGROUND: Postoperative pulmonary complications (PPCs) are major adverse events in neurosurgical patients. This study aimed to develop and validate machine learning models predicting PPCs after neurosurgery. METHODS: PPCs were defined according to the European Perioperative Clinical Outcome standards as occurring within 7 postoperative days. Data of cases meeting inclusion/exclusion criteria were extracted from the anesthesia information management system to create three datasets: The development (data of Huashan Hospital, Fudan University from 2018 to 2020), temporal validation (data of Huashan Hospital, Fudan University in 2021) and external validation (data of other three hospitals in 2023) datasets. Machine learning models of six algorithms were trained using either 35 retrievable and plausible features or the 11 features selected by Lasso regression. Temporal validation was conducted for all models and the 11-feature models were also externally validated. Independent risk factors were identified and feature importance in top models was analyzed. RESULTS: PPCs occurred in 712 of 7533 (9.5%), 258 of 2824 (9.1%), and 207 of 2300 (9.0%) patients in the development, temporal validation and external validation datasets, respectively. During cross-validation training, all models except Bayes demonstrated good discrimination with an area under the receiver operating characteristic curve (AUC) of 0.840. In temporal validation of full-feature models, deep neural network (DNN) performed the best with an AUC of 0.835 (95% confidence interval [CI]: 0.805-0.858) and a Brier score of 0.069, followed by Logistic regression (LR), random forest and XGBoost. The 11-feature models performed comparable to full-feature models with very close but statistically significantly lower AUCs, with the top models of DNN and LR in temporal and external validations. An 11-feature nomogram was drawn based on the LR algorithm and it outperformed the minimally modified Assess respiratory RIsk in Surgical patients in CATalonia (ARISCAT) and Laparoscopic Surgery Video Educational Guidelines (LAS VEGAS) scores with a higher AUC (LR: 0.824, ARISCAT: 0.672, LAS: 0.663). Independent risk factors based on multivariate LR mostly overlapped with Lasso-selected features, but lacked consistency with the important features using the Shapley additive explanation (SHAP) method of the LR model. CONCLUSIONS: The developed models, especially the DNN model and the nomogram, had good discrimination and calibration, and could be used for predicting PPCs in neurosurgical patients. The establishment of machine learning models and the ascertainment of risk factors might assist clinical decision support for improving surgical outcomes.

Objective To investigate the role and possible mechanism of celastrol(Cel)in sodium oxalate(NaOx)-induced acute kidney injury(AKI)and crystal deposition in the kidney tissues in mice.Methods Male C57BL/6 mice(aged 8～12 weeks,weighing 22～24 g)were randomly divided into 3 groups.Saline group(control group,intraperitoneal injection with normal saline and drinking water freely),NaOx group(injured group,intraperitoneal injection of 75 mg/kg NaOx,and drinking water containing 50 μmol/L NaOx),and NaOx+Cel group(treatment group,intraperitoneal injection of 1 mg/kg Cel firstly and then 75 mg/kg NaOx in 24 h later,drinking water containing 50 μmol/L NaOx).All specimens were collected in 24 h after NaOx injection.HK-2 cells were randomly divided into 4 groups:Medium group(no treatment),NaOx group(500 μmol/L NaOx),NaOx+Cel group(400 nmol/L Cel pre-treatment for 2 h followed by 500 μmol/L NaOx treatment),and NaOx+Cel+BA group[8 μmol/L betulinic acid(BA,NF-κB agonist)after the interventions as the NaOx+Cel group].Cells of each group were collected in 24 h after corresponding treatments.Von Koosa and cell adhesion assays were used to observe crystal deposition.HE staining was employed to observe renal histopathology and score the damage.CCK-8 assay was utilized to detect cell viability to obtain the optimal concentrations of NaOx and Cel.Serum urea and creatinine levels were detected.Immunohisotochemical assay was conducted to detect the expression of OPN,CD44,KIM-1,NGAL,p65,IL-1β,BAX,and Caspase-3,and Western blotting was performed for protein levels of OPN,CD44,KIM-1,p65,P-p65 and IL-1β.Results The mice in the NaOx+Cel group showed reduced crystal deposition(P<0.0001),attenuated renal tubular damage(P<0.01),decreased serum urea and creatinine levels(P<0.05),and declined expression levels of the renal adhesion molecules OPN and CD44,the kidney injury molecules KIM-1 and NGAL,the inflammation-associated molecules p65 and IL-1β,and the apoptosis related molecules BAX and Caspase-3 when compared with the NaOx group(P<0.05).In in vitro study,the NaOx+Cel group showed reduced crystal adhesion(P<0.0001),decreased expression of the adhesion molecules OPN and CD44(P<0.05),down-regulation of the inflammatory molecule IL-1β and P-p65/p65 ratio(P<0.05),and down-regulation of the renal injury molecule KIM-1(P<0.05)when compared with the NaOx group.In the NaOx+Cel+BA group,crystal adhesion was significantly increased(P<0.0001),the inflammatory molecule IL-1β and the ratio of P-p65/p65 were increased(P<0.05),and the kidney injury molecule KIM-1 was increased when compared with the NaOx+Cel group(P<0.05).Conclusion Cel may reduce NaOx-induced crystal deposition and AKI by inhibiting NF-κB activation.

Peri-implant diseases have a relatively high incidence,and immune-inflammatory re-sponses are closely associated with peri-implant mucositis and peri-implantitis.The complement sys-tem is a vital component of the immune system.Its activation not only regulates the initiation and pro-gression of inflammatory responses but also plays a crucial role in bone remodeling.This review sum-marizes the roles of the core complement components C3 and C5 in various stages of bone remodeling after implant placement,as well as in peri-implant mucositis and peri-implantitis.The aim of the pa-per was to provide novel insights for the prevention and treatment of peri-implantitis through targeted regulation of complement protein levels.

Objective: To explore the intervention effect of group counseling integrating teadrinking on depression, social avoidance and distress, coping styles and selfesteem among college students, so as to provide references for promoting the psychological health of students. Methods: From March to June 2021, a convenience sampling method was used to recruit 46 college students from a university in Nanjing for intervention project. There were 23 students in intervention group and control group, respectively. The intervention was conducted for 2.5 hours per week across a 6 week period. The intervention group received two sessions of group counseling that incorporated teadrinking experience, and the sessions involved tea knowledge explanation, observation and learning, embodied experience, emotional expression, interpersonal assistance and emotional support, cultural customs and life integration. After the intervention was completed, the control group received onetime group counseling that integrated teadrinking. The Wilcoxon difference test and Mann-Whitney U test were performed to compare the scores of each scale within and between the groups, and the χ2 test was used to compare the detection rates. Results: There were no statistically significant differences in the scores of positive coping, negative coping, selfesteem, social avoidance and distress between the intervention group and the control group (Z=-1.20, -0.33, -0.35, 1.31,P>0.05). There were statistically significant differences in positive coping styles, selfesteem, social avoidance and distress between the intervention group and the control group after the intervention(27.70±5.60，22.05±4.30；30.52±3.63，28.27±4.06；7.43±7.38，13.64±6.79) (Z=-3.31, -2.10, 3.22, P<0.05). The intervention group showed statistically significant differences in social avoidance and distress scores before and after the intervention(11.96±7.47,7.43±7.38) (Z=-2.88), and the depression detection rate decreased(60.9%，30.4%) (χ2=4.29) (P<0.05). There were no statistically significant differences in positive coping, negative coping, selfesteem, social avoidance and distress scores, and depression detection rate between the control group before and after the intervention (Z/χ2=-0.28, -0.42, -1.24, -1.25；1.39, P>0.05). The followup results 1year later showed that there was a statistically significant difference in social avoidance and distress(6.57±6.21,14.16±9.22), and in the detection rates of depression(21.7%,52.2%) between the intervention group and the control group (Z/χ2=2.70,4.57,P<0.05). Conclusions Group counseling integrating teadrinking could improve interpersonal relationships, emotional states, selfesteem levels and coping strategies among college students. Group psychological counseling that incorporates teadrinking can be adopted to improve the mental health status of college students.

ObjectiveTo explore the influencing factors of occupational hand-arm vibration disease (OHAVD) caused by handheld workpiece polishing. Methods A total of 222 OHAVD patients (case group), 275 hand-transmitted vibration-exposed workers (exposed group) and 243 healthy workers without hand-transmitted vibration exposure (control group) in a sports equipment manufacturing enterprise were selected as the study subjects using the convenience sampling method. Worksite survey of occupational health was conducted on these three groups, and the human vibration measurement equipment was used to measure the vibration exposure level of handheld vibration among the study subjects. The 8-hour energy equivalent frequency-weighted vibrating acceleration ［A(8)］ and cumulative vibration exposure level (CVEL) were calculated. Results The prevalence of coldness, numbness, tingling fingers, and vibration-induced white finger was higher in the exposed group and the case group compared with the control group (all P<0.05). The prevalence of the above-mentioned hand symptoms was higher in the case group compared with the exposed group (all P<0.05). The A(8) and CVEL levels of the study subjects in the case group were higher than those in the exposed group (all P<0.05). Binary logistic analysis result showed that age and CVEL were both influencing factors of OHAVD (all P<0.05). According to the restricted cubic spline models, CVEL of the study subjects in the exposed group had a positive nonlinear dose-response relationship with the risk of OHAVD (overall trend P<0.01, nonlinear P<0.01), indicating an increasing risk of OHAVD with increasing CVEL. Conclusion Hand-transmitted vibration exposure is a risk factor for OHAVD. Early intervention should be carried out for hand-transmitted vibration-exposed individuals to reduce vibration-exposed levels and control vibration exposure time.

Objective:To analyze epidemiological characteristics and spatiotemporal clustering of hepatitis A in China from 2005 to 2023.Methods:The incidence data of hepatitis A in China during 2005-2023 were collected from the China Disease Control and Prevention Information System .Results:From 2005 to 2023, a total of 605 509 cases of hepatitis A were reported in China. The average annual reported incidence rate was 2.32/100 000, the incidence was 2.85/100 000 in men and 1.81/100 000 in women, and the incidence was 3.25/100 000 in age group 0-14 years, 2.10/100 000 in age group 15-64 years and 2.49/100 000 in age group ≥65 years , respectively. The case count in farmers was highest (40.57%, 245 639/605 509). The proportion of the cases in jobless or the unemployed increased most obviously (347.32%), and the proportion of the cases in students decreased most significantly (90.27%). The average annual reported incidence rate in the western China was highest (4.45/100 000), followed by that in northeastern China (2.02/100 000), central China (1.89/100 000) and eastern China (1.16/100 000). From 2020 to 2023, the incidence of hepatitis A showed no spatial clustering. From 2005 to 2019, the obvious hot spots and high-high clustering areas mainly distributed in provinces, such as, Sichuan, Qinghai, Xinjiang, Xizang and Gansu. The low-low clustering areas were mainly distributed in Beijing, Tianjin, Hebei, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Henan, Anhui, Jiangxi, Jilin and Liaoning. An independent high-low clustering was found in Shanxi during 2014-2019. A total of 5 high incidence clustering areas were detected through spatiotemporal scanning analysis.Conclusions:The incidence rate of hepatitis A in China declined significantly from 2005 to 2023. The reported incidence rate in the elderly showed no obvious decrease, and the reported cases accounted for the highest proportion in the whole population. Before 2020, the reported incidence rate of hepatitis A showed high-high clustering in western China, the spatiotemporal clustering disappeared from 2020 to 2023, but the reported incidence rate of hepatitis A in western China was still high. It is suggested to pay attention to the prevention and control of hepatitis A in populations at high risk and areas with high incidence of hepatitis A.

Objective:To explore the efficacy, safety, and feasibility of single port laparoscopic liver resection via umbilical cord, and summarize its surgical experience.Method:A retrospective analysis was conducted on 39 patients who underwent liver resection surgery at the Department of Hepatobiliary and Pancreatic Surgery, the Affiliated Hospital of Qingdao University from February 2022 to September 2023. There were 19 patients in the transumbilical single-port laparoscopic group, including 5 males and 14 females, aged (49.6±2.5) years. There were 20 patients in the multi-port laparoscopic group, including 7 males and 13 females, aged (49.9±3.1) years. The intraoperative blood loss, operation time, intestinal recovery time, postoperative hospital stay and postoperative complications were compared between the single-port group and multi-port group.Results:All 39 patients successfully completed the surgery without any additional foramen or conversion to open surgery. The operation time of the single hole group (166.3±59.0) min was longer than that of the multi-port group (123.2±48.0) min, and the difference was statistically significant ( t=2.50, P=0.020). There were no statistically significant differences in intraoperative blood loss, intestinal recovery time, postoperative hospital stay, and postoperative complications between these two groups (all P>0.05). All patients had no postoperative complications such as bleeding, infection, or bile leakage. Follow up for 3~21 months showed no recurrence of primary diseases such as hepatic hemangioma, hepatic adenoma, and intrahepatic bile duct stones. The aesthetic effect of the umbilical incision in the single orifice group was significant, and patient satisfaction was 100%. Conclusion:Umbilical single-port laparoscopic liver resection surgery is safe and feasible, with significant minimally invasive and aesthetic effects.

ObjectiveTo retrospectively analyze the effect of modified Shugan Dingji Decoction （疏肝定悸汤） on the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation. MethodsA retrospective cohort study was conducted using the electronic medical record database of Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine to screen and include patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation from January 1st， 2018， to December 31th， 2021. The included patients were divided into an exposure group and a non-exposure group， each consisting of 100 cases， based on whether they received modified Shugan Dingji Decoction. General information of the patients including age， gender， body mass index， duration of illness and comorbidities， medication history， cardiac structure and function indicators such as left atrial diameter， left ventricular end-diastolic diameter， stroke volume and ejection fraction， and the occurrence of endpoint events assessed through 24-hour dynamic electrocardiography or electrocardiogram to determine the recurrence of paroxysmal atrial fibrillation were collected. Kaplan-Meier （K-M） curves and Log-Rank tests were used to conduct survival analysis on the occurrence of endpoint events in the two groups of patients. Univariate and multivariate Cox regression analyses were used to analyze the impact of various factors on entry into endpoint events. Additionally， a safety assessment was performed by comparing liver and kidney function indicators before and after treatment. ResultsIn the non-exposure group， a total of 49 cases （49.0%） experienced endpoint events， while in the exposure group， there were 26 cases （26.0%）. The Log-rank test indicated significant difference between the two groups （χ²=11.211， P=0.001）. Univariate Cox regression analysis showed that age， duration of illness， hypertension， diabetes， chronic heart failure， left atrial diameter， stroke volume， and the use of modified Shugan Dingji Decoction may be the influencing factors for the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation （P＜0.05 or P＜0.01）. Multivariate Cox regression analysis showed that the risk of endpoint events in the exposure group was significantly lower than that in the non-exposure group （P＜0.01）. Patients with a duration of illness ＞12 months had a significantly higher risk of endpoint events compared to those with a duration of illness ≤12 months （P＜0.01）. Patients without concomitant hypertension had a lower risk of endpoint events compared to those with hypertension （P＜0.05）. Patients with left atrial diameter ＞40 mm had significantly higher risk of endpoint events than those with left atrial diameter ≤40 mm （P＜0.01）. There was no statistically significant difference in liver and kidney function indicators between the two groups before and after treatment （P＞0.05）. ConclusionThe use of modified Shugan Dingji Decoction is a protective factor for patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation， which can help to reduce the recurrence and progression of atrial fibrillation. Long duration of illness， concomitant hypertension， and enlarged left atrial diameter are risk factors for patients to experience endpoint events.
