Objective To analyze the characteristics of colorectal adenoma onset,traditional Chinese medicine(TCM)syndromes,and factors influencing advanced colorectal adenoma.Methods A cross-sectional study was conducted to retrospectively analyze the data of 480 patients with colorectal adenoma admitted to the Department of Gastroenterology of Wangjing Hospital,China Academy of Chinese Medical Sciences,between January 2024 and January 2025 who met the inclusion and exclusion criteria.The hospital case system was used to collect demographic information,basic medical history,general conditions associated with colorectal adenoma,and records of TCM syndrome types,which were compiled into a clinical information Excel spreadsheet.Descriptive statistics were calculated to determine the distribution of demographic information,basic medical history,and TCM syndrome types.The chi-square test or Monte Carlo simulation method was used to analyze the differences in the number,size,pathological type and location of colorectal adenomas,as well as the distribution of TCM syndrome types.Univariate chi-square test was used to analyze the related factors of patients with advanced colorectal adenoma,and the statistically significant variables were included in the multivariate logistic regression analysis to analyze the influencing factors of advanced colorectal adenoma.Results Among the 480 patients with colorectal adenoma,296 were male with an onset age of(60.51±11.17)years,and 184 were female with age of(61.65±11.87)years.There were 233 patients(46.46％)aged 45 to 64.There were 269 cases(56.04％)of overweight individuals.Adenomas smaller than 1 cm accounted for 73.33％(352/480).Among the number of adenomas,single adenomas accounted for 66.46％(319/480).Among the pathological types,tubular adenoma accounted for 86.67％(416/480).The left colon accounted for 80.0％(384/480)of the affected sites.The main clinical manifestations included abdominal distension(20.63％,99/480),abdominal pain(16.25％,78/480),diarrhea(9.79％,47/480),among others.The main syndrome types in traditional Chinese medicine are damp-heat syndrome of the large intestine(25.83％,124/480)and spleen deficiency with excessive dampness syndrome(22.94％,110/480).There was a statistically significant difference in the distribution of TCM syndrome types among patients of different age groups(P=0.010).Multitype adenoma(OR=4.504,95％CI:2.819～7.198,P<0.001)and the right colon site(OR=2.166,95％CI:1.146～4.092,P<0.05)are independent risk factors for advanced colorectal adenoma.Conclusion Colorectal adenomas are more common in men and tend to occur in middle-aged people.Adenomas under 1 cm are the most common.Single adenomas and tubular adenomas are more common.The left half of the colon is a common site of occurrence.Common clinical symptoms include abdominal distension,abdominal pain,diarrhea,etc.Damp-heat syndrome of the large intestine is the most common type of syndrome in traditional Chinese medicine.The number of multiple adenomas and the location of the right colon are independent risk factors for advanced colorectal adenomas.

Objectives:To examine the feasibility of using foundation model in computer vision for echocardiographic left ventricular ejection fraction measurement. Methods:Based on the most extensive publicly accessible repository of echocardiographic loops,EchoNet-Dynamic,featuring 10024 recordings from individual patients,a foundation model in computer vision,VideoMAE V2,was fine-tuned,validated,tested using 7460,1288,and 1276 echocardiographic loops,respectively. Results:The mean absolute error between left ventricular ejection fraction measurements of VideoMAE V2 and expert's measurements was 3.94％ (95％CI:3.79％-4.11％).The Pearson's correlation coefficient was 0.91 (95％CI:0.89-0.92).Additionally,VideoMAE V2 demonstrated exceptional accuracy in identifying patients with a left ventricular ejection fraction below 50％,achieving an AUC of 0.96 (95％CI:0.95-0.97). Conclusions:This study validates the feasibility of using foundation model in computer vision for measuring left ventricular ejection fraction in echocardiographic loops and lays the foundation for the development of a generalized multimodal automated interpretation system for echocardiography.

ObjectiveTo explore the effect and regulatory mechanism of notoginseng total saponins on apoptosis of mammary gland cells in rats with mammary gland hyperplasia. MethodSixty female non-pregnant SD rats were randomly divided into control group， model group， Notoginseng total saponins low-， medium- and high-dose （10， 20， 40 mg·kg^-1， respectively） groups and tamoxifen group （1.8 mg·kg^-1）， 10 rats per group. Rat model of mammary gland hyperplasia was established by intramuscular injection of estradiol benzoate and progesterone. Oral administration was performed according to the experimental dose of each group， once a day for 30 consecutive days. The rats in the control group and the model group were given equal volume of normal saline by gavage every day. After administration， the diameter of the second pair of nipples of the rats was measured with vernier calipers， and breast tissue samples were collected and stained with hematoxylin and eosin （HE） to observe the pathological changes. Immunohistochemistry was used to determine the expression of apoptosis regulators B-cell lymphoma-2 （Bcl-2）-associated X （Bax） and Bcl-2， and Western blot was conducted to detect the expression of phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway-related proteins. ResultCompared with the control group， the model group had increased diameter of the second pair of nipples （P<0.05）， elevated volume of mammary lobules and number of acinus， diffuse mammary gland hyperplasia， and up-regulated expression of Bcl-2 protein， increased ratio of p-PI3K/PI3K， p-Akt/Akt， p-mTOR/mTOR （P<0.05） and decreased expression of Bax in the mammary gland （P<0.05）. Compared with the conditions in the model group， the diameter of the second pair of nipples of the rats in the notoginseng total saponins low-， medium- and high-dose groups and tamoxifen group was decreased （P<0.05）， and the number of mammary lobules and acinus and the amount of secretions were reduced. In addition， the mammary gland hyperplasia was alleviated， and a decrease was observed in the expression of Bcl-2 protein and the ratio of p-PI3K/PI3K， p-Akt/Akt， p-mTOR/mTOR （P<0.05）， and an increase in the expression of Bax （P<0.05）. ConclusionNotoginseng total saponins could improve mammary gland hyperplasia in rats， and its mechanism was related to regulating PI3K/Akt/mTOR pathway and promoting apoptosis of mammary gland cells.

Periodontitis is associated with abnormal purine metabolism, which is manifested by increased uric acid in host blood and increased expression of the purine-degrading enzyme, xanthine oxidoreductase (XOR), in periodontal tissues. Both XOR and uric acid are pro-oxidative and pro-inflammatory mediators under pathological conditions. Animal studies have found that injection of uric acid promotes the progression of periodontitis and that febuxostat (an XOR inhibitor) improves tissue destruction in periodontitis. Therefore, blocking the source of uric acid may be a therapeutic strategy to control the progression of periodontitis. In this article, the rationality of XOR inhibitors as potential therapeutic drugs for periodontitis is reviewed. The literature review results suggest that XOR inhibitors show antioxidative, anti-inflammatory, and anti-osteoclastic effects, and XOR inhibitors show clinical efficacy in the treatment of infectious, inflammatory and osteolytic diseases. Although there is no direct evidence to support the finding that XOR inhibitors can ameliorate periodontal microecological dysbiosis, these drugs can modulate intestinal microflora dysbiosis, and there is indirect evidence to support a beneficial effect of XOR inhibitors on periodontal microecological dysbiosis. In conclusion, XOR inhibitors may be used as immunomodulators for the adjuvant treatment of periodontitis by inhibiting inflammation, oxidative stress and anti-osteoclast effects.
