Phacoemulsification with intraocular lens implantation(Phaco+lOL)has become the main treatment for cataracts due to small incision and fast recovery. Phacoemulsification can damage the conjunctiva, cornea and other ocular surface tissues, causing local inflammation, which in turn leads to eye dryness and discomfort after surgery. According to studies, patients who suffer from phacoemulsification most experience dry eye syndrome within 24 h, which gradually worsens and reaches its peak in the following 1 wk, seriously affecting their quality of life. The review aims to comprehensively investigate the effects of preoperative patient physical conditions and local ocular status, intraoperative maneuvers and postoperative treatments on postoperative dry eye, with the expectation of formulating scientific and effective preventive measures for potential dry eye patients after phacoemulsification, and providing a theoretical basis for postoperative dry eye treatment.

Objective To investigate the effects and related mechanisms of mitochondrial-derived peptide MOTS-c on glycochenodeoxycholic acid (GCDCA)-induced injury in human hepatocytes (THLE-3 cells). Methods THLE-3 cells were cultured in vitro and treated with different concentrations of GCDCA and MOTS-c. The optimal concentrations of GCDCA and MOTS-c were determined by cell counting kit (CCK)-8 method. Subsequently, THLE-3 cells were treated or pre-treated with GCDCA (200 µmol/L), MOTS-c (15, 30, 60 µmol/L), the multidrug resistance protein 2 (MRP2) inhibitor Probenecid (500 µmol/L), and the nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor ML385 (10 µmol/L). Cell proliferation was assessed by CCK-8 method. Lactate dehydrogenase (LDH) levels in the culture medium were measured by biochemical method. Cell apoptosis rates were determined by flow cytometry. MRP2 messenger RNA (mRNA) levels were detected by real-time quantitative polymerase chain reaction (RT-qPCR). MRP2 and Nrf2 protein expression levels were analyzed by Western blotting. Results As the concentration of GCDCA increased, the proliferation activity of THLE-3 cells gradually decreased, while LDH activity in the culture medium and apoptosis levels increased, and the expression levels of MRP2 in the cells decreased (all P<0.05). Treatment with 30 and 60 µmol/L MOTS-c significantly enhanced the proliferation activity of THLE-3 cells exposed to GCDCA, upregulated the expression of MRP2 and Nrf2, and reduced LDH activity and apoptosis levels (all P<0.05). Co-treatment with Probenecid partially reversed the protective effects of MOTS-c on GCDCA-induced THLE-3 cells injury, while co-treatment with ML385 partially inhibited the induction of MRP2 expression by MOTS-c in THLE-3 cells exposed to GCDCA. Conclusions MOTS-c may alleviate GCDCA-induced injury in human hepatocytes (THLE-3 cells), and its mechanism may be related to the upregulation of MRP2 expression mediated by Nrf2.

Chinese Journal of Experimental Traditional Medical Formulae 2025;31(8):244-249
ObjectiveTo perform a multi-source data fusion analysis of the clinical literature on traditional Chinese medicine (TCM) treatment of gout, explore the front hotspots in this field, and mine the clinical consensus and medication patterns in the TCM treatment of gout with the syndrome of dampness-heat accumulation, thus providing reference for the standardized treatment of this disease. MethodsCNKI, Wanfang, and VIP were searched for the relevant literature. COOC14.9/VOSviewer was used to perform multi-source data fusion analysis of clinical literature on the TCM treatment of gout and construct a visual knowledge map for exploring the research hotspots and frontiers of the TCM treatment of gout. The Traditional Chinese Medicine Inheritance Support System (V3.0) was used to establish the database of TCM treatment of gout with the syndrome of dampness-heat accumulation and explore the medication pattern and prescription characteristics. ResultsThe number of published clinical articles on the TCM treatment of gout has remained high. The research hotspots included comparative studies on the etiology and pathogenesis of gout, identification and typing, prescription composition, and clinical efficacy. A large amount of data has been accumulated in the medicine use experience and the summarization of therapeutic effects. The medication patterns in the TCM treatment of gout with the syndrome of dampness-heat accumulation were mined from the articles that were published during 2019-2023. It was revealed that clinically used drugs can be categorized into 9 groups according to their efficacy. Among them, the drugs with the effects of promoting urination and draining dampness were the richest and had the highest frequency. Meanwhile, the drugs with the effects of resolving dampness and expelling wind-dampness were also commonly used in clinical practice. The combined use of drugs with effects of eliminating dampness, resolving dampness, and expelling dampness plays a key role in the treatment of gout with the syndrome of dampness-heat accumulation. Secondly, heat-clearing drugs are also commonly used, with the types and frequency close to those of urination-promoting and dampness-draining drugs. In addition, drugs with the effects of activating blood and eliminating stasis are commonly prescribed. The prescriptions modified from Simiaowan were commonly used, and the most commonly used drug was Coicis Semen. The analysis of drug combination applications and core drug combinations showed that the core drugs used in the treatment of gout with the syndrome of dampness-heat accumulation were Coicis Semen, Phellodendri Chinensis Cortex, Atractylodis Rhizoma, Achyranthis Bidentatae Radix, Smilacis Glabrae Rhizoma, Dioscoreae Hypoglaucae Rhizoma, Alismatis Rhizoma, and Clematidis Radix et Rhizoma, which were closely related. Coicis Semen was an assistant and guide drug in Simiaowan, while it was the most commonly used in the treatment of gout with the syndrome of dampness-heat accumulation. ConclusionsClinical studies on the TCM treatment of gout are in-depth and diverse, and the core medicinal combination was essentially modified Simiaowan. Coicis Semen, with the highest frequency, has a special efficacy in the treatment of gout with the syndrome of dampness-heat accumulation and is worthy of further in-depth study.
6.Association between screen time and anxiety-depression symptoms and their comorbidity among middle school students in Taiyuan City
Chinese Journal of School Health 2025;46(7):980-984
Objective:
To investigate the association between screen time (ST) during leisure time and anxiety-depression symptoms among middle school students, so as to provide a basis for formulating relevant intervention measures.
Methods:
From November to December 2023, a stratified cluster random sampling method was used to select 2 542 students from junior and senior high school in Taiyuan City. A self designed questionnaire, the Generalized Anxiety Disorder Scale (GAD-7), and the Patient Health Questionnaire (PHQ-9) were used to investigate ST and anxiety/depression symptoms among middle school students. The Logistic regression model was used to explore the association of ST with symptoms of anxiety and depression, as well as with anxiety and depression comorbiditles (CAD).
Results:
The detection rates of anxiety symptoms, depression symptoms, and CAD were 13.69%, 15.77%, and 10.11%, respectively. The median ST was 2.00 h/d [interquartile range ( IQR =2.38) for weekly averages], with 0.33 h/d ( IQR =1.67) on work days and 5.00 h/d ( IQR=5.50) on rest days. Logistic regression analysis indicated that the total ST of mobile phones during rest days ( OR =1.07, 1.10, 1.11) and the averages ST of mobile phones over a week ( OR = 1.20 , 1.22, 1.29), as well as the total ST of all screen types during rest days ( OR =1.04, 1.04, 1.05) and the averages ST of all screen types over a week ( OR =1.08, 1.09, 1.21) were positively correlated with anxiety symptoms, depression symptoms, and CAD (all P <0.01).
Conclusions
Among middle school students in Taiyuan City, screen time is positively correlated with symptoms of anxiety or depression and the comorbidity of anxiety and depression, especially smartphone screen time and weekend screen use. Therefore, measures should be implemented to reduce unnecessary screen time among middle school students, especially the use of mobile phones, in order to mitigate the occurrence of anxiety and depression.

Objective:To analyze the factors influencing the theoretical score of graduation examination of standardized residency training in a class-A tertiary general hospital in Shanghai from 2018 to 2021, and establish prediction models, and to provide a reference for further improving the quality of residency training.Methods:We collected the data of 556 residents who participated in the residency training graduation examination at the hospital from 2018 to 2021. Binary regression and logistic regression analyses were used to determine the association of residents' basic information, their routine assessment results at the bases, and the base performance assessment score (indicating the bases' training quality) with theoretical graduation examination results; and prediction models for the theoretical graduation examination score were established, using binary regression and logistic regression methods to construct model datasets. SPSS 26.0 was used for statistical analysis.Results:From 2018 to 2021, a total of 556 people participated in the residency training graduation examination at the hospital. The first-time pass rate of the first station theoretical examination station was 97.48% (542/556). Trainees graduating from double first-class schools had the highest first-time pass rate of 98.09% (359/366); doctoral students had the highest first-time pass rate of 98.59% (140/142); and residents of the two-year training program had the highest first-time pass rate of 98.34% (297/302). According to the binary regression analysis of categorical variables such as residents' basic information, the base level was associated with whether residents passed the theoretical examination ( P<0.05). According to the logistic regression analysis of residents' routine assessment scores and the base performance assessment score, the annual theoretical assessment score, the first-time theoretical score of the national medical licensing examination, the annual professional performance test score, and the base performance assessment score were key factors affecting the theoretical graduation examination score ( P<0.05). In the regression analysis associated with the theoretical graduation examination score, the annual professional performance test score showed the highest regression coefficient and the highest variance inflation factor, indicating strong multicollinearity. Therefore, the annual professional performance test score was important in predicting the theoretical score of the graduation examination. Conclusions:This study used binary regression and logistic regression models to analyze the possible factors affecting the theoretical graduation examination score and the degree of association, and also established two prediction models of the theoretical graduation examination score to predict trainees at risk. Through implementing the concept of hierarchical progression, adding personalized tutoring, realizing information management for residency training, and providing intelligent early intervention, the pass rate of residency training graduation examination is expected to be further improved, ultimately achieving the purpose of improving the quality of residency training.

Objective:To explore the relationship between the location of puncture points and the occurrence of complications in X-ray assisted percutaneous fluoroscopic gastrostomy (PFG).Methods:The retrospective and descriptive study was conducted. The clinical data of a total of 67 patients, including the gender, age, etiology, nutritional status. All data of 67 patients who received with X-ray assisted PFG surgery during the period from January 2021 to January 2023 in Xuanwu Hospital of Capital Medical University were retrospectively analyzed. There were 42 males and 25 females, aged (57.3±12.6) years, ranging from 22 to 90 years old. The technical success rate, distribution of puncture points, and incidence of complications were described. The relationship between different gastric types and puncture sites and complications was analyzed. Measurement data with normal distribution were represented as mean±standard deviation ( ± s). Count data were represented as numbes and Pearson chi-square test was used between groups. Results:A total of 67 patients with dysphagia were included in our study, all of whom underwent X-ray assisted PFG in our institution. The technical success rate was 100%. In the empty state, the puncture point of 30 patients was located at the midpoint of the gastric cavity, 28 cases were leaned towards to the greater curvature, and 9 cases were leaned towards to the lesser curvature. No operation-related severe complications occurred, such as acute gastrointestinal bleeding and perforation. A total of 7 patients experienced varied degree of pain complication during follow-up period, including 5 cases of waterfall type stomach, which showed significant differences with other gastric types ( χ2=3.889, P=0.049). Pain complication of 6 patients was related to the location of the puncture point, with 5 cases leaning towards to the greater curvature and 1 case leaning towards to the lesser curvature. Conclusions:PFG surgery is safe and reliable, the gastric wall puncture point is not completely consistent between the empty and dilated gastric state. The occurrence of postoperative pain may be related to the patient′s gastric type pearson and changes in the position of the puncture point at the empty gastric state.
