As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Objective: To explore the association of outdoor activity time and sleep duration with screening myopia in primary school students, so as to provide strategies for myopia prevention. Methods: Through a convenience sampling method, a survey was conducted among 4 248 primary school students aged 7-13 years from three primary schools in Xihu District, Nanchang City, Jiangxi Province from May to July, 2023. The average daily outdoor activity time and sleep duration on both weekdays and weekends were investigated in primary school students by using a self designed questionnaire. Uncorrected visual acuity tests and non cycloplegic autorefraction were measured by professional optometrists. Inter group comparisons were conducted using the Chi square test. Logistic regression model was used to analyze the association of outdoor activity time and sleep duration with screening myopia. Results: The detection rate of screening myopia in primary school students was 33.6%, with the rate in boys (32.0%) lower than that in girls (35.3%), and the difference was statistically significant ( χ 2=5.11, P =0.02). The analysis results of Logistic regression showed that after adjusting for factors such as gender, grade and parental education level, both average daily outdoor activity time ＜2 h on both weekdays and weekends ( OR =1.27, 95% CI =1.11-1.46) and sleep duration <10 h ( OR =1.17, 95% CI =1.01- 1.35 ), as well as their combined effect ( OR =1.57, 95% CI =1.25-1.98), were associated with an increased risk of screening myopia in primary school students(all P <0.05). Subgroup analysis results indicated that compared to boys ( OR =1.46, 95% CI = 1.07 -1.99), girls( OR =1.73, 95% CI =1.22-2.44) with insufficient outdoor activity time and sleep duration had a higher risk of screening myopia(both P <0.05). Conclusions There is a negative correlation of outdoor activity time and sleep duration with screening myopia in primary school students. Outdoor activity time and extending sleep duration should be increased to reduce the risk of myopia in primary school students.

This study aimed to establish an analytical method capable of simultaneously quantifying the prototype components of Si-Ni-San and screening their metabolites to elucidate its tissue distribution and metabolic characteristics in an ulcerative colitis (UC) mouse model. To this end, an integrated analysis strategy based on UPLC-QqQ-MS was developed and validated, combining the targeted quantification of 12 prototype components with a pseudo-targeted metabolite screening technique based on ion pair list-triggered data-dependent acquisition. Samples were extracted with 80% methanol (100 mg/mL) and processed with internal standards. Separation was achieved on a Waters Acquity UPLC HSS PFP column using a gradient elution with a mobile phase consisting of acetonitrile and 5 mmol/L ammonium acetate containing 0.1% formic acid. Analysis was performed using an electrospray ionization (ESI) source in multiple reaction monitoring mode. Methodological validation confirmed that all parameters met the requirements for bio-sample analysis. Application of this method revealed that the content of Si-Ni-San prototype components in the colon, liver, and kidneys of UC mice was significantly higher than that in healthy mice. Furthermore, the number of phase II metabolites was markedly greater than that of phase I metabolites in all tested samples. The results demonstrate the reliability of the established method and preliminarily reveal the tissue distribution characteristics of Si-Ni-San under UC conditions and its metabolism pattern dominated by phase II conjugation, which provides a methodological basis and experimental data for further in-depth research into its effective target tissues and pharmacodynamic material basis.

Patients with inflammatory bowel disease (IBD) require long-term pharmacotherapy. Due to the wide variety of clinically available drugs, medication safety has become increasingly concerning. As an indispensable component of pharmaceutical formulations, drug excipients may induce various adverse reactions, including rash, allergic responses, and gastrointestinal discomfort, and may even lead to severe organic injury. However, they are often overlooked in clinical practice. Therefore, identifying and managing excipient-related adverse reactions is crucial for ensuring medication safety. To address this issue, this article systematically reviews common excipients in IBD therapeutics, the underlying mechanisms of excipient-induced adverse reactions, and corresponding management strategies, aiming to enhance clinicians' awareness of excipient-related issues, improve their ability to recognize and manage such reactions, and ultimately ensure patient safety.

Objective To comprehensively evaluate the causal relationship between gut microbiota and 9 respiratory diseases, explore whether there are common mechanisms among these 9 respiratory diseases, and delves into the potential commonalities of pre-chronic obstructive pulmonary disease (pre-COPD) by focusing on COPD, emphysema, and chronic bronchitis. Methods Mendelian randomization was used to explore the causal relationship between gut microbiota and 9 respiratory diseases, sensitivity analysis was conducted, and robustness was verified. Single nucleotide polymorphisms of common gut microbiota were mapped to genes to explore their common mechanisms. Results Mendelian randomization studies found that 66 gut microbiota had a causal relationship with 9 respiratory diseases, and 15 gut microbiota might be potential common mechanisms for these 9 respiratory diseases, with a total of 85 potential genes. GO functional enrichment analysis found that these genes were mainly enriched in biological functions such as synaptic transmission, synaptic membrane, cytokine activity, and growth factor binding. KEGG enrichment analysis showed that these genes were mainly enriched in glutamatergic synapses, relaxin signaling pathway, calcium signaling pathway, Rap1 signaling pathway, and PI3K-Akt signaling pathway. Allisonella and Prevotellaceae might be protective factors for pre-COPD, while Howardella might be a risk factor. Ten protective genes and six risk genes for the pre-COPD were identified. Conclusion This study further confirms the correlation between the lung-gut axis and the lung-colon connection, explores the potential common mechanisms of 9 respiratory diseases, investigates the potential mechanisms of pre-COPD based on the common gut microbiota of COPD, chronic bronchitis, and emphysema, and provides some ideas for the early prevention and treatment of COPD, and diagnosis of pre-COPD from the perspective of gut microbiota.

Objective: To explore the micro associations and key bridge nodes between physical fitness indicators and anxiety/depressive symptoms among college students using network analysis, so as to provide a theoretical foundation for promoting physical and mental health of college students. Methods: From September to October 2025, a combination of purposive sampling and cluster sampling was employed to select 2 158 college students from three universities in Xuzhou City. Seven physical fitness indicators were measured and standardized according to the National Student Physical Health Standard. The Generalized Anxiety Disorder Scale-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9) were used to assess anxiety and depressive symptoms. Independent samples t-test was used for intergroup comparisons of physical fitness indicators and psychological symptom scores. A gaussian graphical model (GGM) was constructed to calculate node and bridge strength, followed by stability analyses. Results: The detection rates of anxiety and depressive symptoms among college students were 21.3% and 24.5%, respectively. Male participants demonstrated superior performance in physical fitness indicators such as vital capacity, 50 meter sprint, and standing long jump compared to female participants, whereas females exhibited better results in the sit and reach test ( t =48.35, -44.82 , 70.21, -16.51, all P <0.01). Regarding psychological indicators, female participants showed higher scores of anxiety and depressive symptoms than males ( t =-4.15, -4.46, both P <0.01). Physical fitness and psychological symptoms were predominantly negatively correlated. "feeling tired" and "not being able to stop or control worrying" were the symptoms with the highest centrality in the network of physical fitness and phychological symptoms among college students (standardized strengths were 2.15 and 1.98, respectively). Among the bridge indicators, the "1 000 m (male)/800 m (female) run" exhibited the highest strength (0.85), outperforming "vital capacity" (0.35); it was linked to the symptom cluster primarily by negatively predicting "feeling tired" (edge weight=-0.38). The network stability was excellent of physical fitness and phychological symptoms among college students (correlation stability coefficient= 0.60 ). Conclusions Endurance capacity serves as the most critical bridge connecting physical and mental health, and its decline is closely related to intensified feelings of fatigue. Colleges should prioritize endurance training as a core target for promoting college students mental health.

Objective:To discuss the expression of Rh family C glycoprotein(RHCG)in the esophageal squamous cell carcinoma(ESCC)tissue and its effect on the malignant biological behavior of ESCC cells,and to clarify the value of RHCG as a diagnostic and prognostic marker for the ESCC patients.Methods:A total of 143 ESCC tissue samples and 105 adjacent normal tissue samples were collected.Using immunohistochemical staining method,141 ESCC samples were divided into two groups:RHCG low expression group(immunohistochemistry score≤6)and RHCG high expression group(immunohistochemistry score>6).Immunohistochemical method was used to detect the RHCG protein expression in 143 ESCC tissues and 105 normal tissues,and the relationship between the clinicopathological characteristics of the ESCC patients was analyzed.Receiver operating characteristic(ROC)curve and Kaplan-Meier survival analysis were used to evaluate the value of RHCG in diagnosis and prognosis of the ESCC patients;univariate and multivariate COX regression analysis were used to determine the independent risk factors affecting the prognosis of the ESCC patients.Gene Expression Profiling Interactive Analysis(GEPIA2)database was used to analyze the expression of RHCG mRNA in various tumor tissues.The ESCC TE-1 cells were cultured and transfected in to 6-well cell culture plates with different Lipofectamine2000∶RHCG ratios;the cells in RHCG transfection group were transfected with weights of 2.0,2.5,and 3.0 μg for 24 and 48 h,respectively,and the cells in NC group transfected with empty vector as control.Western blotting method was used to detect the RHCG protein expression level in the TE-1 cells in various groups after transfection at different concentrations and verify the optimal transfection conditions;cell counting kit-8(CCK-8)assay was used to detect the proliferation activities of the TE-1 cells;plate clone formation assay was used to detect the colony formation numbers of the TE-1 cells;Transwell chamber assay was used to detect the numbers of migrating TE-1 cells.Results:Compared with adjacent normal tissue,the RHCG gene expression level in various cancer tissues including ESCC,glioblastoma multiforme,and head and neck squamous cell carcinoma was significantly decreased(P<0.05).RHCG protein was mainly located on the cell membrane of normal esophageal squamous epithelial cells;the RHCG protein expression intensity in ESCC tissues was lower than that in adjacent normal esophageal tissue(χ2=109.373,P<0.001),and the patients in RHCG low expression group had poorer differentiation than those in RHCG high expression group(P=0.041).The area under the curve(AUC)value of RHCG for diagnosing ESCC was 0.86,with sensitivity and specificity of 95.1%and 75.0%,respectively;the Kaplan-Meier survival analysis results showed that compared with high RHCG expression group,the patients in low RHCG expression group had shorter survival time and poorer prognosis[harard ratio(HR)=0.269,95%confidence interval(CI):0.113-0.639,P=0.020];the COX regression analysis results showed that low RHCG expression could serve as an independent risk factor affecting the prognosis of ESCC[HR=4.569,95%CI=1.315-15.877,P=0.017)].The Western blotting results verified that the optimal transfection condition was 3.0 μg RHCG plasmid for 48 h,at which time RHCG overexpression was optimal and RHCG protein expression level was highest.The CCK-8 assay results showed that compared with control group,the proliferation activity in RHCG overexpression group was decreased on the 4th day after cell seeding(P<0.001).In the TE-1 cells,the colony formation number of the TE-1 cells in RHCG over-expression group was lower than that in control group(t=17.70,P<0.001).The Transwell chamber assay results showed that compared with control group,the number of migrating cells in RHCG over-expression group was decreased(t=23.74,P<0.001).Conclusion:RHCG expression is decreased in ESCC tissues and associated with poor prognosis in ESCC patients;overexpression of RHCG can inhibit the proliferation and migration of the TE-1 cells,providing a theoretical basis for RHCG as a novel diagnostic and prognostic marker and therapeutic target for ESCC.
