ObjectiveTo establish a high-performance liquid chromatography(HPLC) for the quantitative analysis of multiple components in Gegen Qinlian tablets, and to comprehensively evaluate the quality of samples from different manufacturers by integrating chemical pattern recognition and technique for order preference by similarity to ideal solution(TOPSIS), in order to provide a reference basis for quality evaluation and control of Gegen Qinlian tablets. MethodsHPLC was employed to determine the contents of 10 components in 28 batches of Gegen Qinlian tablets collected from 6 manufacturers, and taking the detection results as variables, SIMCA 14.1 and SPSS 26.0 were employed for cluster analysis(CA), principal component analysis(PCA), and orthogonal partial least squares-discriminant analysis(OPLS-DA) to identify key components affecting the quality. Then, TOPSIS analysis was employed to rank the quality of Gegen Qinlian tablets from the 6 manufacturers and establish a comprehensive quality evaluation method. ResultsA quantitative method for Gegen Qinlian tablets was established. After methodological validation, the method was found to be stable and reliable, and could be used for the quantitative analysis of this preparation. The contents of 3′-hydroxy puerarin, puerarin, 3′-methoxy puerarin, daidzein, coptisine hydrochloride, epiberberine, jatrorrhizine hydrochloride, berberine hydrochloride, palmatine hydrochloride and baicalin in 28 batches of samples were 3.58-7.35, 24.88-42.32, 4.20-9.36, 4.33-7.60, 2.52-6.44, 0.93-4.10, 0.58-3.05, 10.68-22.92, 0.82-4.82, 11.73-60.16 mg·g-1, respectively. Among them, puerarin, berberine hydrochloride and baicalin all met the limit requirements for this preparation specified in the 2025 edition of the Pharmacopoeia of the People's Republic of China. CA and PCA clustered the 28 batches of samples into 5 categories, PCA extracted 2 principal components with a cumulative variance contribution rate of 90.588%, and OPLS-DA screened out 4 differential markers with variable importance in the projection(VIP) values>1.0, namely baicalin, 3′-hydroxy puerarin, coptisine hydrochloride and palmatine hydrochloride, which might be the main components affecting the quality of Gegen Qinlian tablets. TOPSIS analysis showed that the comprehensive score of each evaluation index(Ci) values of different manufacturers were different. Among them, the Ci of manufacturer B was ranked higher, indicating potentially superior quality, while the Ci of manufacturer A was ranked lower, suggesting potentially inferior quality. ConclusionThis study establishes a quantitative method for Gegen Qinlian tablets, and the content uniformity of the same manufacturer is good, while there are differences in the contents of active components among different manufacturers. Through the chemical pattern recognition analysis, it is found that the content differences of Gegen Qinlian tablets may be related to baicalin, 3′-hydroxy puerarin, coptisine hydrochloride and palmatine hydrochloride.

Chinese Journal of School Health 2026;47(5):728-731
Objective:
To analyze the epidemiological characteristics of varicella among nursery children in Shenzhen from 2015 to 2024, and to evaluate the impact of optimizing varicella vaccine (VarV) immunization strategies on varicella incidence.
Methods:
Varicella incidence data for nursery children in Shenzhen from 2015 to 2024 were obtained from the China Disease Prevention and Control Information System. The study period was divided into three phases:one dose self pay VarV (January 2015 to October 2017), two dose self pay VarV (November 2017 to October 2019), and two dose free VarV (November 2019 to December 2024). Interrupted time series (ITS) analysis was conducted to assess changes in the level and trend of varicella incidence associated with each phase of policy implementation.
Results:
A total of 27 517 varicella cases was reported among nursery children from 2015 to 2024, with an average annual incidence of 514.01/100 000. During the same period, 136 clustered outbreaks were reported in nursery institutions, involving a cumulative total of 1 091 cases. ITS analysis showed that during the self pay 1 dose stage, the varicella incidence among nursery children showed an upward trend, with an average monthly increase of 2.58/100 000 (95% CI =2.21/ 100 000 -2.95/100 000, P <0.01). After the implementation of the self pay 2 dose strategy, the incidence decreased, with a change in incidence of -26.12/100 000 (95% CI =-37.30/100 000 to -14.94/100 000) and a change in slope of -2.65/100 000 (95% CI = -3.38/100 000 to -1.93/100 000)(all P <0.01). After the implementation of the free 2 dose strategy, the incidence decreased further, with a change in incidence of -40.03/100 000 (95% CI =-50.39/100 000 to -29.66/100 000, P <0.01) and a change in slope of -0.56/100 000 (95% CI =-1.20/100 000-0.08/100 000, P =0.09).
Conclusion
The gradual optimization of the VarV vaccination strategy in Shenzhen from self pay 1 dose to free 2 dose has significantly reduced the varicella incidence among nursery children, demonstrating good short term control and long term intervention effectiveness.

This study explores methodological issues in the design, evaluation, and reporting of randomized controlled trials (RCTs) under the concept of "syndrome dominating disease". The discussion focuses on key aspects including the adaptability of trial design, the screening of research participants, the standardization of syndrome differentiation, the balance between intervention individualization and standardization, the integration of multi-dimensional outcome measures, and the limitations of existing evaluation and reporting tools when applied to this type of research, along with corresponding recommendations and future perspectives. Regarding research design, it is recommended to select or draw upon innovative design concepts such as basket trials and subgroup-based dynamic/static parallel-group designs, in order to innovate the design format of RCTs. Meanwhile, criteria for participant screening, TCM syndrome differentiation, and disease classification should be standardized. The balance should be appropriately achieved between intervention individualization and standardization, and a multidimensional assessment system encompassing TCM syndromes, disease-specific outcomes, and patient-reported outcomes should be established. For risk of bias assessment and research reporting, it is recommended,to develop specialized assessment and reporting tools based on existing instruments, in order to standardize the assessment and reporting of study findings. Future research may further explore the potential applications of artificial intelligence in the study design, risk-of-bias assessment, and reporting quality assessment of RCTs based on the "syndrome dominating disease" model, with a particular focus on methodological optimization, data integration, and enhancement of research quality.

With the development of science and technology, electronic devices have become an inevitable part of our daily life and work. There has been an increase of interest in the use of various video display terminals(VDT). The ocular surface is the first barrier of the visual system to resist the damage of the external environment. In recent years, the number of patients with dry eye has consistently increased with the excessive use of VDT. Blue light produced by VDT, with wavelengths ranging from 400 to 500 nm, has a high energy in visible light. Therefore, blue light may also be an important risk factor for dry eye. In particular, the outbreak of COVID-19 has left people worldwide suffering from increased blue light, which promotes further research into dry eye caused by blue light emitted from VDT. In this review, we summarize the recent studies on the role of blue light produced by VDT in dry eye to provide reference for future related research.

Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a rare autosomal dominant hereditary disorder characterized by hyperuricemia, gout, impaired urinary concentration, and progressive renal failure. It is primarily caused by mutations in uromodulin (UMOD) gene. This study reports a family with ADTKD in which whole-exome sequencing and Sanger sequencing identified a missense mutation in the UMOD gene, c.761A>C (p.H254P), present in both the proband and affected relatives. According to American College of Medical Genetics and Genomics (ACMG) guidelines, this variant is classified as likely pathogenic. The mutation results in an amino acid substitution that may impair UMOD protein folding and intracellular trafficking. UMOD gene mutations are associated with ADTKD, and genetic testing plays a vital role in the early diagnosis and treatment of this condition, highlighting its importance in the diagnosis of rare kidney diseases.

This study investigated the role of the nuclear factor of activated T cells c3 (NFATc3) in vascular smooth muscle cells (VSMCs) during aortic aneurysm and dissection (AAD) progression and the underlying molecular mechanisms. Cytoplasmic and nuclear NFATc3 levels were elevated in human and mouse AAD. VSMC-NFATc3 deletion reduced thoracic AAD (TAAD) and abdominal aortic aneurysm (AAA) progression in mice, contrary to VSMC-NFATc3 overexpression. VSMC-NFATc3 deletion reduced extracellular matrix (ECM) degradation and maintained the VSMC contractile phenotype. Nuclear NFATc3 targeted and transcriptionally upregulated matrix metalloproteinase 9 (MMP9) and MMP2, promoting ECM degradation and AAD development. NFATc3 promoted VSMC phenotypic switching by binding to eukaryotic elongation factor 2 (eEF2) and inhibiting its phosphorylation in the VSMC cytoplasm. Restoring eEF2 reversed the beneficial effects in VSMC-specific NFATc3-knockout mice. Cabamiquine-targets eEF2 and inhibits protein synthesis-inhibited AAD development and progression in VSMC-NFATc3-overexpressing mice. VSMC-NFATc3 promoted VSMC switch and ECM degradation while exacerbating AAD development, making it a novel potential therapeutic target for preventing and treating AAD.

Objective:To compare the clinical outcomes of immediate breast reconstruction using latissimus dorsi flap with implant versus mesh with implant based on BREAST-Q evaluation.Methods:From the clinical database of the First Affiliated Hospital of Nanjing Medical University, the patients who underwent immediate breast reconstruction after total mastectomy from January 2020 to December 2023 were selected as the research subjects. All breast reconstruction surgeries were performed by the same surgeon. Patients were divided into two groups according to surgical methods: the latissimus dorsi muscle flap combined with implant immediate breast reconstruction group (LD group) and the mesh combined with implant immediate breast reconstruction group (mesh group). Patients were followed up in outpatient clinics or by telephone one year after surgery. The BREAST-Q was used to evaluate the surgical outcomes of both groups from four dimensions: psychosocial well-being, sexual well-being, chest-physical well-being, and breast satisfaction. The score range for each dimension was 0-100, with higher scores indicating greater patient satisfaction with quality of life and surgical outcomes. Statistical analysis was performed using SPSS 22.0 software. Normally distributed measurement data were expressed as Mean ± SD, and comparisons between the two groups were performed using independent sample t-test. Count data were expressed as number of cases and percentages, and comparisons between groups were performed using chi-square test or Fisher’s exact test. P<0.05 was considered statistically significant. Results:A total of 123 patients were included, with 59 patients in the LD group and 64 patients in the mesh group. In the LD group, the mean age was (37.7±7.0) years, body mass index (BMI) was (22.6±2.6) kg/m 2, and clinical tumor staging showed 2, 22, 30, and 5 cases for stages 0, Ⅰ, Ⅱ, and Ⅲ, respectively. In the mesh group, the mean age was (39.1±7.0) years, BMI was (22.6±2.8) kg/m 2, and clinical tumor staging showed 1, 25, 38, and 0 cases for stages 0, Ⅰ, Ⅱ, and Ⅲ, respectively. There were no statistically significant differences between the two groups in baseline characteristics including age, BMI, and clinical tumor staging (all P>0.05). One year after surgery, the BREAST-Q result showed no statistically significant differences between the LD group and mesh group in psychosocial well-being [(83.0±19.8) points vs. (80.8±19.3) points] and sexual well-being [(62.1±30.4) points vs. (65.8±25.6) points] (all P>0.05). However, the LD group had lower chest-physical well-being scores than the mesh group [(40.6±9.7) points vs. (45.1±9.6) points, P<0.05], while breast satisfaction scores were higher in the LD group than in the mesh group [(68.0±17.8) points vs. (59.8±12.6) points, P<0.01]. Conclusion:Immediate breast reconstruction by both latissimus dorsi flap with implant and mesh with implant can improve patients’ psychosocial and sexual well-being by enhancing breast appearance. However, LD technique provides better breast satisfaction, while the mesh technique offers advantages in physical well-being of the chest wall and upper body. Surgeons should select the most appropriate breast reconstruction technique based on patients’ anatomical conditions, treatment history, and individual needs to optimize postoperative quality of life and satisfaction.
