Abstract To achieve identification and intervention synergy with regards to critical windows for the prevention and control of childhood hypertension, the study adopts a life course perspective to systematically review the developmental pathways of childhood hypertension, identify key challenges facing current prevention and control efforts, and discuss monitoring and intervention strategies during critical windows of opportunity. By promoting continuous, multi setting screening and dynamic monitoring, improving measurement standardization and diagnostic feasibility, developing child specific risk assessment tools and strengthening coordinated interventions across families, schools, communities and individuals, the prevention of childhood hypertension can shift away from passive detection toward proactive risk management and primary prevention, thereby providing robust evidence and practical pathways to reduce the lifelong burden of cardiovascular disease.

Objective: To systematically evaluate the association between random urinary electrolyte levels and hypertension among children and adolescents in Guizhou Province, so as to provide evidence for region specific dietary guidance and interventions. Methods: In 2023, a total of 2 480 children and adolescents aged 6 to 17 years were recruited from a nine-year coherent style school in Guizhou Province in a children health cohort, with follow ups conducted in 2024 and 2025. Random urine samples were collected to measure urinary sodium, potassium, calcium, and chloride, and the urinary sodium to potassium ratio (Na/K) was calculated. The diagnosis of hypertension was based on the criteria established by the Chinese Guidelines for Hypertension Prevention and Treatment (2024 revised edition) and relevant research. Linear mixed models and multinomial Logistic regression were used to assess the associations of urinary electrolytes with systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and the risk of hypertension. Results: At baseline, SBP, DBP, and MAP were 102.33 (94.33, 110.33), 61.33 (56.33, 67.00) and 75.22 (69.67, 81.33)mmHg among children and adolescents, respectively. After adjusting for potential confounders and two follow-ups, higher urinary Na/K ratio was positively associated with higher of SBP ( β=0.054, 95%CI =0.028- 0.081 ) and MAP ( β=0.038, 95%CI =0.010-0.066), as well as higher risks of hypertension ( OR=1.248, 95%CI =1.006-1.548) (all P <0.05). Higher of urinary chloride levels were positively associated with higher of SBP ( β=0.088, 95%CI = 0.009- 0.167), whereas higher of urinary potassium (SBP: β=-0.062, 95%CI =-0.096 to -0.028; MAP: β=-0.041, 95%CI = -0.078 to -0.005) and calcium levels (SBP: β=-0.036, 95%CI =-0.065 to -0.007) were negatively associated with blood pressure (all P < 0.05 ). Conclusion The urinary Na/K, as a comprehensive electrolyte marker, more stably reflects sodium load and excretory pressure in children and adolescents, and may serve as an early predictor of hypertension risk.

Objective To investigate the relationships of computed tomography (CT) angiography (CTA)-derived coronary plaque properties with platelet function and whole blood cell-derived inflammatory markers in elderly patients with coronary heart disease. Methods The clinical data of 142 elderly patients with coronary heart disease who underwent coronary CTA examination in the hospital between April 2022 and April 2025 were retrospectively analyzed. The CT value of CTA, platelet function parameters (mean platelet volume, platelet-derived growth factor BB, von Willebrand factor), and whole blood cell-derived inflammatory markers were recorded at admission. The correlations of the CT value of CTA-derived coronary plaque properties with platelet function parameters and whole blood cell-derived inflammatory markers in elderly patients with coronary heart disease were analyzed using Pearson correlation coefficients. Based on the evaluation of CTA-derived coronary plaque properties, the patients were divided into a soft plaque group (CT value ≤ 60 HU), a calcified plaque group (CT value ≥ 130 HU), and a mixed plaque group (60 HU < CT value < 130 HU). The platelet function parameters (mean platelet volume, platelet-derived growth factor BB, von Willebrand factor) and whole blood cell-derived inflammatory markers (systemic immune-inflammation index, systemic inflammation response index, neutrophil-to-lymphocyte ratio, and monocyte-to-lymphocyte ratio) on admission were compared among the three groups. Results The coronary CTA examination showed 37 (26.06%) cases in the calcified plaque group, 47 (33.10%) cases in the soft plaque group, and 58 (40.84%) cases in the mixed plaque group. The CT values were (189.57 ± 22.14) HU for the calcified plaque group, (31.74 ± 4.12) HU for the soft plaque group, and (94.52 ± 8.29) HU for the mixed plaque group. The levels of platelet function parameters and whole blood cell-derived inflammatory markers at admission were in the following order: soft plaque group > mixed plaque group > calcified plaque group, and the differences were statistically significant (P < 0.05). After adjustment for sex, age, cardiac function grading, hypertension, diabetes, and blood lipids as covariates, partial correlation analysis revealed that the CT value of CTA-derived coronary plaque properties in elderly patients with coronary heart disease was negatively correlated with the levels of platelet function parameters and whole blood cell-derived inflammatory markers (P < 0.05). Conclusion In this study, the coronary plaque CT value in elderly patients with coronary heart disease was negatively correlated with the levels of platelet function parameters and whole blood cell-derived inflammatory markers. Furthermore, increasing plaque instability may be associated with more pronounced platelet activation and a heightened systemic inflammatory state.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

Of 578 patients with moderate to high risk, the proportion of postoperative adjuvant therapy was 15.15%(5/33) in 2011, 14.71%(10/68)in 2012, 22.45%(11/49) in 2013, 29.09%(16/55) in 2014, 41.38%(24/58) in 2015, 46.15%(24/52) in 2016, 32.81%(21/64)in 2017, 60.00%(45/75) in 2018, 60.42%(29/48) in 2019, 61.84%(47/76) in 2020, respectively. Of 253 patients underwent postoperative adjuvant therapy, 247 cases received imatinib had 6 cases received sunitinib. (3) Comparison of clinicopathological characteristics of GIST with non-gastric origin and gastric origin. Of 847 patients, 262 cases had non-gastric origin and 585 cases had gastric origin. There were significant differences in gender, the number of tumor, tumor maximum diameter, Ki-67 index, risk classification of NIH, and R 0 resection between the two groups ( χ2=8.62, 8.40, 12.97, 6.57, Z=-6.15, χ2=17.19, P<0.05). (4) Analysis of influencing factors for recurrence-free survival rate in GIST patients. Results of multivariate analysis showed that the year of initial diagnosis, primary site, tumor maximum diameter, mitotic image, risk classification of NIH, R 0 resection, genetic testing and postoperative adjuvant therapy were independent factors influencing recurrence-free survival rate in GIST patients with initial surgical resection ( hazard ratio=0.58, 0.61, 2.00, 1.71, 5.81, 2.56, 0.65, 0.38, 95% confidence interval as 0.39-0.85, 0.45-0.83, 1.46-2.74, 1.24-2.35, 3.16-10.69, 1.63-4.02, 0.46-0.94, 0.25-0.56, P<0.05). Conclusions:GIST with initial surgical resection is common located in stomach, with high positive rate in CD117 and Dog-1. The number of people undergoing genetic testing and targeted therapy for GIST is increasing year by year. There are significant differ-ences in clinicopathological characteristics between GIST with non-gastric origin and gastric origin. The year of initial diagnosis, primary site, tumor maximum diameter, mitotic image, risk classifica-tion of NIH, R 0 resection, genetic testing and postoperative adjuvant therapy are independent factors influencing recurrence-free survival rate in GIST patients with initial surgical resection.

Objective To construct a predictive model for the occurrence of lower extremity deep vein thrombosis(DVT)after internal fixation surgery for thoracolumbar fractures by using extreme gradient boosting(XGBoost).Methods Data of 220 patients who underwent internal fixation surgery for thoracolumbar fractures in the First Affiliated Hospital of Wenzhou Medical University from January 2019 to December 2022 was collected.The dataset was divided into a training set(154 cases)and a testing set(66 cases).The training set was processed by using the synthetic minority over-sampling technique and the predictive model was build based on XGBoost.The performance was compared on the testing set by using area under receiver operating characteristic curve,accuracy,F1 score,sensitivity and specificity.The interpretability analysis base on SHAP was conducted to quantify the degree of contribution of influencing factors.Results The XGBoost model outperformed logistic regression,support vector machine and random forest models on multiple metrics,with an area under the curve of 0.761 on the original testing set.The decision curve indicated that the XGBoost model has clinical application value.Conclusion The XGBoost model based on factors such as age,body mass index,and postoperative albumin,D-dimer,total protein,erythrocyte sedimentation rate,prothrombin time can effectively predict the occurrence of lower extremity DVT after internal fixation surgery for thoracolumbar fractures,which has good potential for clinical application.

Objective: To investigate the pathological changes and conduct viral gene analysis of OPA and MVD co-occurrence in Inner Mongolia, China. Methods: Using gross pathology, histopathology, immunohistochemistry, ultrastructural pathology, PCR, and sequence analysis, we investigated the concurrent infection of JSRV and MVV in 319 Dorper rams slaughtered in a private slaughterhouse in Inner Mongolia, in 2022. Results: Of the 319 rams included, 3 showed concurrent JSRV and MVV infection. Gross lung pathology showed diffuse enlargement, consolidation, and greyish-white miliary nodules on the lung surface; the trachea was filled with a white foamy fluid; hilar and mediastinal lymph nodes were significantly enlarged. Histopathology results revealed typical OPA and MVD lesions in the lung tissue. Immunohistochemical results were positive for JSRV envelope protein (Env) in the tumor cells and MVV CA in alveolar macrophages. Transmission electron microscopy showed several virions and autophagosomes in the lung tissue, severely damaged mitochondria, and the induced mitophagy. Nucleotide sequences obtained for JSRV env and MVV gag showed the highest homology with the Inner Mongolian strains of JSRV env (JQ837489) and MVV gag (MW248464). Conclusions and Relevance: Our study confirmed that OPA and MVD co-occurrence and identified the pathological changes in Inner Mongolia, China, thereby providing references for the identification of concurrent JSRV and MVV infections.

The incidence of adenocarcinoma of esophagogastric junction is gradually increa-sing. The metastasis of the distal lymph node of upper gastric cancer with tumor diameter <4 cm is rare, and proximal gastrectomy can meet the requirements of radical treatment. Reflux esophagitis, food stasis, anastomotic stenosis, and poor nutrient absorption are important factors affecting the quality of life of patients undergoing proximal gastrectomy. With the continuous promotion of laparoscopic radical gastrectomy, laparoscopic proximal gastrectomy with lymph node dissection has been standardized. However, the method of digestive tract reconstruction has not yet reached standardization consensus, and anti-reflux has become a hot spot in clinical attention in recent years. Through interpositioned jejunum reconstruction to achieve anti-reflux effect, or retaining or rebuilding the anti-flow structure of esophageal residual gastric anastomosis include a variety of additional anti-reflux surgery, which have their own different advantages and disadvan-tages. The authors introduce in detail a variety of mainstream anti-reflux surgery, and its modified program, with the aim of providing reference for colleagues and maximizing the benefits of patients.
