Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Objective To assess the nutritional status of patients undergoing preventive ileostomy and identify the factors that influence the status,thereby providing guidance for medical staff to formulate nutritional intervention strategies.Methods Convenient sampling was used to select 239 patients undergoing preventive ileostomy who were attending follow-up visits or hospitalized while awaiting stoma closure at 4 tertiary hospitals in Guangzhou from November 2023 to July 2024.Data was collected by a general information questionnaire and the Patient-Generated Subjective Global Assessment tool.Factors influencing nutritional status were analyzed by multivariable ordinal Logistic regression.Results Of the 239 patients,227 provided valid responses.The nutritional status was categorized as follows:64 patients(28.19％)had good nutrition or were at risk of malnutrition;104(45.81％)exhibited moderate malnutrition;59(25.99％)had severe malnutrition.Multivariable ordinal Logistic regression analysis revealed that preoperative cumulative chemotherapy cycles,postoperative duration,age,current dietaiy type,use of oral nutritional supplements(ONS),enterostomy-related complications,and stoma self-care ability were significant predictors of nutritional status(P＜0.05).Conclusion Patients undergoing preventive ileostomy are at a high risk of moderate to severe malnutrition and ONS provided to patients did not result in a meaningful improvement in their nutritional health.Specifically,those patients with a higher number of cumulative preoperative chemotherapy cycles,shorter postoperative recovery time,aged ≥ 65 years,liquid diet or semi-liquid diet,experiencing enterostomy-related complications,or poor stoma self-care ability,are particularly vulnerable to malnutrition.These findings underscore the need for medical staff to formulate intervention strategies based on these factors to improve nutritional status of patients undergoing preventive ileostomy.

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of childbearing age, with the clinical manifestations of oligomenorrhea or amenorrhea, hyperandrogenism, and anovulatory infertility, and it is often accompanied by metabolic disorders such as obesity, insulin resistance, hyperinsulinemia, and glucose and lipid metabolism disorders. Women with PCOS often have nonalcoholic fatty liver disease (NAFLD) and other metabolic-associated diseases, and PCOS and NAFLD are related in terms of pathogenesis and treatment. This article reviews the research advances in PCOS with NAFLD in recent years.

Portopulmonary hypertension (POPH) is an increase in pulmonary artery pressure that occurs on the basis of portal hypertension. As a member of the BMP family, bone morphogenetic protein 9 (BMP9) not only has the osteogenic activity, but can also protect endothelial integrity and maintain vascular homeostasis. This article reviews the pathogenesis of POPH, the physiological expression and role of BMP9, and related research advances in the BMP9 signaling pathway and its involvement in pulmonary hypertension and vascular remodeling, thereby exploring the possibility of BMP9 as a new biomarker for POPH to assist in the diagnosis of POPH.

Objective:To determine the risk profile of venous thromboembolism (VTE) and evaluate VTE prophylaxis implementation of the hospitalized cancer patients in the DissolVE 2 study.Methods:The data of hospitalized cancer patients in the DissolVE 2 study were analyzed. The risk distribution of VTE, preventive measures and in-hospital VTE events of hospitalized patients with tumors were described by percentage and 95% confident interval (CI).Results:A total of 1 535 cancer patients were included. According to the Padua score, 826 (53.8%) patients were at low risk of VTE, while 709 (46.2%) patients were at high VTE risk. VTE events occurred in 4 low-risk patients (0.5%; 95% CI: 0.1%, 1.2%) and 5 high-risk patients (0.7%; 95% CI: 0.2%, 1.6%). The overall incidence was 0.6% (9/1 535, 95% CI: 0.3%, 1.1%). Among patients with high VTE risk, 666 (93.9%) did not receive any VTE prophylaxis, and only 11 (1.6%) patients received appropriate VTE prophylaxis. Among patients who received VTE prevention, no VTE event was observed. Conclusions:Nearly half of the hospitalized cancer patients are at high risk of VTE, but most of them don′t receive VTE prophylaxis. The results reflect the insufficient management of VTE risk for hospitalized cancer patients in China, and improvement of awareness and practice of VTE prophylaxis is urgently needed.

The prevalence of hyperuricemia in elderly population aged over 60 years in China ranges from 5.5%-19.3%.With the population ageing, the number of the patients with hyperuricemia can be expected to grow.Whether elderly patients with asymptomatic hyperuricemia need active uric acid-lowering therapy is still a debatable entity because of lacking relevant clinical guidelines.In this paper, the metabolic process of uric acid, pathophysiologic mechanism of hyperuricemia, the treatment principle of hyperuricemia in combination with different comorbidities, and specific therapeutic schedules for asymptomatic hyperuricemia as well as drug therapy progress were reviewed as follows.

OBJECTIVE： To study the effects of 60Co-γ radiation on the botanical traits and property of Andrographis paniculata， and to screen suitable irradiation dose. METHODS： The seeds of A. paniculata were irradiated by 60Co-γ rays with different irradiation doses（0，10，20，50，100，200，300 Gy）. The botanical traits indexes of A. paniculata as seed germination rate， root length， seedling rate， seedling height， leaf area， fresh weight， dry weight， stomata number of lower epidermis of leaf， and its property indexes as the contents of andrographolide， dehydrated andrographolide and chlorophyll， activity of T-SOD enzyme and CuZn-SOD enzyme， were determined after radiation. The coefficient of variation （CV） was calculated. The linear regression analysis was performed for seedling rate， and medial lethal dose was calculated. The correlation analysis was performed between the parameters of botanical trait and quality property with irradiation dose. Cluster analysis was conducted for M1 generation of A. paniculata in different irradiation dose groups by connection method combined with squared euclidean distance. RESULTS： Different irradiation doses showed different effects on botanical traits and property of A. paniculata. According to the average value of CV， the index of botanical traits was ranked as leaf area ＞ fresh weight ＞ dry weight ＞ plant height ＞ root length ＞ stomata number ＞ seedling rate ＞ germination rate； among different irradiation dose groups， the coefficient of variation was ranked as 50 Gy＞200 Gy＞100 Gy＞20 Gy＞10 Gy＞300 Gy＞0 Gy. According to the average value of CV， the index of property was ranked as dehydrated andrographolide content＞andrographolide content＞chlorophyll content＞CuZn-SOD enzyme activity＞T-SOD enzyme activity； among different irradiation dose groups， the coefficient of variation was ranked as 100 Gy＞50 Gy＞200 Gy＞20 Gy＞10 Gy＞300 Gy＞0 Gy. The medial lethal dose was 195.10 Gy. According to the botanical traits， M1 generation of A. paniculata of 7 dose groups could be divided into 4 types. According to the property， M1 generation of A. paniculata of 7 dose groups could be divided into 3 types. CONCLUSIONS： The suitable irradiation dose interval for irradiating A. paniculata is 50-200 Gy.
