BACKGROUND:The pathogenesis of moyamoya disease is unclear,and there is a lack of early diagnostic methods and effective medical treatments.OBJECTIVE:To identify biomarkers of moyamoya disease through machine learning,and analyze the therapeutic mechanism of Bu Huang Si Wu Tang in moyamoya disease.METHODS:Moyamoya disease gene dataset from gene expression omnibus database was retrieved.R language was used to screen differentially expressed genes and perform enrichment analysis on differentially expressed genes.Moyamoya disease biomarkers were screened using least absolute shrinkage and selection operator and support vector machine-recursive feature elimination machine learning algorithms.A diagnostic model was constructed by establishing a column chart,and its clinical utility and diagnostic value were evaluated and further validated through detecting clinical serum markers of patients with moyamoya disease.In vitro experiments were performed to observe the effect of Bu Huang Si Wu Tang on umbilical vein endothelial cells under oxygen glucose deprivation,and the main components of Bu Huang Si Wu Tang were selected for molecular docking and molecular dynamics simulation with the screened targets to explore its potential mechanism.RESULTS AND CONCLUSION:This study identified 76 differentially expressed genes,mainly enriched in immune and metabolic related pathways.Two potential biomarkers,complement factor D(CFD)and DKFZp434L192,were obtained through machine learning.The calibration curve,decision curve analysis,and clinical impact curve showed that the column chart had good predictive ability.qRT-PCR analysis showed that CFD and DKFZp434L192 expression levels were significantly upregulated in patients with moyamoya disease(P<0.001).In vitro experiments showed that Bu Huang Si Wu Tang significantly enhanced the activity and migration ability(P<0.01)of umbilical vein endothelial cells under oxygen glucose deprivation.Molecular docking results showed that all four active ingredients of Bu Huang Si Wu Tang could bind to the target site,and the dynamic simulation results further verified its binding stability.To conclude,CFD and DKFZp434L192 exhibit good diagnostic efficacy for moyamoya disease and can serve as potential diagnostic biomarkers and therapeutic targets for moyamoya disease.Bu Huang Si Wu Tang has a certain protective effect on vascular endothelial cells under ischemic conditions,which may be related to CFD.

Objective:To investigate the influencing factors and prognosis of early recurrence after gastrectomy for gastric cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 2 078 patients who underwent gastrectomy for gastric cancer at six medical centers across China, including Fudan University Shanghai Cancer Center et al, between January 2012 and June 2023 were collected. There were 1 449 males and 629 females, aged (59±11) years. Patients were classified as early recurrence and late recurrence based on the time of post-operative recurrence. Observation indicators: (1) comparison of clinicopathological characteristics between gastric cancer patients with different recurrence types; (2) recurrence and metastasis of tumor; (3) survival of patients after postoperative recurrence of gastric cancer; (4) analysis of influencing factors for early recurrence after gastrectomy for gastric cancer. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the rank sum test. Multivariate analysis was conducted using the Logistic regression model. Kaplan-Meier method was used to calculate survival rate and plot survival curve, and Log-rank test was used for survival analysis. Results:(1) Comparison of clinicopathological characteristics between gastric cancer patients with different recurrence types. Among the 2 078 patients, 1 452 cases had early recurrence and 626 cases had late recurrence. There were significant differences in preoperative carcinoembryonic antigen, preoperative CA19-9, preoperative CA72-4, preoperative albumin, tumor diameter, neoadjuvant therapy, R 0 resection, combined organ resection, scope of gastric resection, nerve and vessel infiltration, degree of tumor differentiation, pathological N staging, pathological TNM staging between early and late recurrence patients ( P<0.05). (2) Recurrence and metastasis of tumor. Among the 2 078 patients, 200 cases had local recurrence, 1 213 cases had hematogenous metastases, 392 cases had distant lymph node metastases, and 731 cases had peritoneal metastases. Among the 1 452 early recurrence patients, 142 cases had local recurrence, 834 cases had hematogenous metastases, 289 cases had distant lymph node metastases, and 507 cases had peritoneal metastases. Among the 626 late recurrence patients, 58 cases had local recurrence, 379 cases had hematogenous metastases, 103 cases had distant lymph node metastases, and 224 cases had peritoneal metastases. One patient may have multiple forms of recurrence and metastasis. There was no significant difference in the above indica-tors between early and late recurrence patients ( χ2=0.13, 1.74, 3.40, 0.14, P>0.05). (3) Survival of patients after postoperative recurrence of gastric cancer. All 2 078 patients were followed up until death after recurrence, with a follow-up time of 31(range, 9?147)months. The 1-, 2-, 3-, and 5-year overall survival rates after recurrence were 33.5%, 17.2%, 10.1%, and 3.3% in early recurrence patients, versus 44.2%, 21.6%, 12.8%, and 5.8% in late recurrence patients, respectively, showing a significant difference in overall survival after recurrence between the two groups ( hazard ratio=0.84, 95% confidence interval as 0.76?0.92, P<0.05). (4) Analysis of influencing factors for early recurrence after gastrectomy for gastric cancer. Results of multivariate analysis showed that combined organ resection, total gastrectomy, pathological TNM staging as stage Ⅲ were independent risk factors for early recurrence after gastrectomy for gastric cancer ( odds ratio=1.31, 1.32, 1.34, 95% confidence interval as 1.01?1.70, 1.06?1.65, 1.05?1.71, P<0.05) and normal preoperative tumor markers, neoadjuvant therapy, R 0 resection were independent protective factors for early recurrence ( odds ratio=0.61, 0.50, 0.38, 95% confidence interval as 0.49?0.76, 0.35?0.72, 0.25?0.58, P<0.05). Conclusions:Compared with patients with late recurrence after gastric cancer surgery, patients with early recurrence have a poor prognosis, in which liver metastases is more common. Combine organ resection, total gastrectomy, pathological TNM staging as stage Ⅲ are independent risk factors for early recurrence, and normal preoperative tumor markers, neoadjuvant therapy, R 0 resection are independent protective factors for early recurrence after gastrectomy for gastric cancer.

Objective:To describe the positive rates of high-risk human papillomavirus (HR-HPV) DNA and serum-neutralizing antibody in cervical intraepithelial neoplasia (CIN) tissues of rural women in Xiangyuan County, Shanxi Province, and evaluate the association of HR-HPV DNA and neutralizing antibody positive status with the occurrence of CIN.Methods:In a cohort of 1 897 women aged 35-45 years established by the Shanxi Province Cervical Cancer Screening StudyⅠ, DNA typing (SPF10 PCR-DEIA-LiPA25) was performed by using tissue samples of women with positive HR-HPV test results [Hybrid CaptureⅡ(HC2)] or abnormal cytological or pathological results. Serum HR-HPV neutralizing antibody detection was conducted with multicolor pseudovirion-based neutralization assay. Cochran-Armitage trend test was used to analyze the changing trend of the positive rate of HR-HPV DNA and neutralizing antibody with the progression of CIN. Multivariate logistic regression models were used to evaluate the influence and multiplicative interaction of HR-HPV DNA and neutralizing antibody positive status on the occurrence of CIN. The relative excess risk ( RERI), attributable proportion of interaction ( AP), and the synergy index ( SI) of the interaction were calculated to evaluate the additive interaction of HR-HPV DNA and neutralizing antibody on the occurrence of CIN. Results:The positive rate of any type of HR-HPV DNA (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68) in 479 women who were HC2 positive or had abnormal cytological or pathological detection results was 37.16%. In normal, CIN1, CIN2, and CIN3+ groups, the HR-HPV DNA positive rates were 18.03%, 49.53%, 90.24% and 94.59%, respectively. The positive rate of any type of HR-HPV neutralizing antibody was 63.88%. In normal, CIN1, CIN2, and CIN3+ groups, the positive rates of HR-HPV neutralizing antibody were 63.95%, 57.94%, 70.73%, and 72.97%, respectively. The positive rate of any type of HR-HPV neutralizing antibody was 53.31% in 1 418 women who were HC2 negative and had normal cytopathology, and the most common types were HPV51 (27.36%) and HPV39 (24.96%). Multivariate logistic regression analysis showed that any type of HR-HPV DNA positive status ( OR=9.15, 95% CI: 5.99-14.20, P<0.001) was the independent factor for the occurrence of CIN, HR-HPV neutralizing antibody positive status was not associated with the occurrence of CIN ( OR=0.95, 95% CI: 0.61-1.48, P=0.815). The OR value of the multiplication of HR-HPV DNA and neutralizing antibody positive status of the occurrence of CIN was 1.63 (95% CI: 0.67-3.95), P=0.283. Quantitative analysis of interaction showed that RERI was 1.65 (95% CI:-3.56-6.86), SI was 1.28 (95% CI: 0.58-2.82), and AP was 0.19 (95% CI:-0.36-0.75). Conclusions:HR-HPV DNA positive status was a risk factor for the occurrence of CIN, but neutralizing antibody positive status was not associated with the occurrence of CIN. They had no significant multiplicative or additive interaction with the occurrence of CIN.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To analyze the medical operation efficiency of the Beijing-Tianjin-Hebei region, so as to provide references for optimizing medical resource allocation in the area.Methods:Based on the China Statistical Yearbook (2012 to 2023), data regarding healthcare operational inputs (3 indicators including number of healthcare institutions, number of healthcare personnel, and number of beds in healthcare institutions) and outputs (6 indicators including number of patients treated and discharged, etc.) in the Beijing-Tianjin-Hebei region were included, and the DEA-Malmquist index model was employed to analyze healthcare operational efficiency in the region. The grey prediction model was used to predict the number of healthcare institutions, healthcare personnel, and beds in healthcare institutions from 2023 to 2027. Results:From 2011 to 2022, the overall efficiency of medical operations in Beijing and Tianjin showed an increasing trend, with total factor productivity of 1.213 1 and 1.246 0, respectively. However, the overall efficiency of medical operations in Hebei was showing a downward trend, with a total factor production of 0.933 1 and a scale efficiency of 0.909 5. The number of healthcare institutions, healthcare personnel, and beds in healthcare institutions showed an upward trend in the Beijing-Tianjin-Hebei region from 2023 to 2027.Conclusions:The medical operational efficiency in Beijing and Tianjin was consistently improving. The utilization rate of medical resources in Hebei was relatively low, accompanied by a persistent decline in medical operational efficiency. The Beijing-Tianjin-Hebei region should further enhance the rational allocation of medical resources, so as to promote the coordinated development of the regional healthcare system.

Objective To compare the effects of Tripterygium wilfordii polyglycosides,cyclophosphamide,and cisplatin on the establishment of a mouse model of diminished ovarian reserve(DOR).Methods Mice were randomly divided into the following treatment groups:control(Ctrl),Tripterygium wilfordii polyglycosides(TWP),cyclophosphamide(CTX),and cisplatin(DDP).Mice in the TWP group received a 50 mg/kg suspension of Tripterygium wilfordii polyglycosides by gavage for 14 days,mice in the CTX group received a 20 mg/kg cyclophosphamide suspension by intraperitoneal injection for 14 days,and mice in the DDP group received a 1.5 mg/kg cisplatin solution by intraperitoneal injection for 14 days.The body weight,uterine index,and ovarian index were recorded,the estrous cycle was monitored using the vaginal smear method,and the levels of anti-Mullerian hormone(AMH),estradiol(E2),follicle stimulating hormone(FSH),and luteinizing hormone(LH)were detected using ELISA.Hematoxylin and eosin staining was used to detect ovarian follicle development.The rates of oocyte maturation and fertility were analyzed.Results The three treatment groups of mice all showed the following:significantly decreased body weight and ovarian index(P＜0.05);apparent disorder of the estrous cycle;significantly decreased levels of AMH and E2(P＜0.05);decreased and increased rates of developing follicles and atretic follicles,respectively(P＜0.05);and significantly decreased rates of oocyte maturation,pregnancy,and live birth(P＜0.05).Conclusions DOR mouse models were successfully constructed using Tripterygium wilfordii polyglycosides,cyclophosphamide,or cisplatin,as evidenced by decreased body weight and ovarian index,disordered estrous cycle and hormones,and DOR function,resulting in reduced rates of oocyte maturation,pregnancy,and total number of live births.These DOR effects were most appropriate in the cyclophosphamide group.
