Irritable bowel syndrome （IBS） is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years， traditional Chinese medicine （TCM） has made progress in multiple aspects of IBS research and treatment， including syndrome distribution， development of TCM formulas， clinical efficacy evaluation， external therapies， and psychosocial regulation. However， it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria， and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment， combining TCM external therapies such as acupuncture， moxibustion and acupoint application）， and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies， artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas， so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

Objective To compare the positioning errors and the motion of acromioclavicular joint in breast cancer patients with integrated cervicothoracic thermoplastic membrane and breast bracket fixation,and to provide reference for accurate irradiation of upper and lower clavicular region.Methods Sixty-three pa-tients with breast cancer who were treated in the radiotherapy center of the hospital from November 1,2021 to August 9,2023 were selected as the study objects,and were divided into the integrated cervicothoracic thermo-plastic membrane group(n=32)and breast bracket group(n=31)according to different positioning meth-ods.The translation errors of left and right direction(X),head and foot direction(Y)and ventral and dorsal direction(Z)and the rotation errors of sagittal plane(Rx),cross section(Ry)and coronal plane(Rz)of the two groups were analyzed,and the movement amplitude and three-dimensional displacement of acromioclavic-ular joint were measured respectively.Results Compared with the breast bracket group,X translation errors[(0.18±0.14)cm vs.(0.15±0.12)cm]and Z translation errors[(0.19±0.14)cm vs.(0.16±0.14)cm]of the cervicothoracic thermoplastic memberane group were greater,Z translation error[(0.21±0.17)cm vs.(0.22±0.21)cm]and Rx rotation error of cervical and sternoclavicular joints[(0.93±0.87)° vs.(1.08±0.92)°]were smaller,Rz rotation error[(1.00±0.94)° vs.(0.95±0.86)°]was greater,and the motion ΔX of acromioclavicular joint[(0.18±0.15)cm vs.(0.25±0.21)cm]was smaller,the difference was statistically significant(P＜0.05).Conclusion Integrated cervicothoracic thermoplastic membrane can be used as a solu-tion for prophylactic irradiation of breast cancer in the upper and lower clavicular region and for radiation leak-age in the presence of metastasis.

Objective To evaluate the efficacy of in-situ split liver transplantation (ISSLT) in children.Methods From June 2015 to August 2018,10 liver grafts from DBD were split in-situ.All the donors were male,and the median age of the donors was 28.5 year old (18-48 year).One left half graft and 9 left lateral lobe grafts (including 2 reduced size grafts) were transplanted to 10 pediatric recipients.Four grafts were transplanted in our center,and the rest 6 grafts were shared to other two transplant center.The primary diseases of the recipients included biliary atresia (8/10),hepatic sinus obstruction syndrome (1/10) and Alagille syndrome (1/10).The median age of the recipients was 10 month (7 month-11 year),and the mean body weight was 9.8 ± 6.6 kg (5-28 kg).Results All liver grafts were split in-situ.The mean split time of liver grafts was 88.5 ± 18.9 min.The mean weight of split grafts was 336.7-± 85.4 g.All recipients were subjected to piggyback liver transplantation.Operation time was 542.5 ± 112.1 min.Anhepatic time was 52.0 ±-13.5 min.GRWR was (3.98 ±0.96)％.GRWR of two cases was more than 5％,so segment Ⅲ was partially reduced.During the follow-up period,9 cases were alive and 1 case died due to multiple organ failure 1 day after liver transplantation.Conclusions ISSLT can enlarge the graft pool for children and achieve good results.

Objective To investigate the factors influencing the prevalence of echinococciasis in Gansu Province.Methods With the method of stratified random sampling,all the administrative villages in pastoral areas,half pastoral areas,agriculture and urban areas in the 72 counties in Gansu Province were selected;according to the layers of the population of the county population proportion calculated,the layer investigation numbers were determined,and a total of 16 administrative villages were selected in each county.In the 16 administrative villages,more than 200 people of permanent residents were surveyed in each village (shortage was made up from a nearby village),at least 3 200 people were investigated in a county.By using the combined method of inquiry and field observation,natural factors,such as drinking water,farming and animal husbandry production data were surveyed.All data were analyzed using SPSS 19.0 statistical software.Unauy linear and multiple linear regression analysis of influencing factors and the relationship between the prevalence were analyzed.Results Unary linear regression analysis showed that longitudes,latitudes,altitudes,average annual temperature,annual rainfalls,secondary industries,animal husbandry towns,drinking water sources,the number of epidemic towns,epidemic villages,per capita net incomes in animal husbandry regions,the total number of livestock and the number of sheep were factors influencing the prevalence of echinococciasis (F =4.705,P ＜0.05).Latitude,altitude,animal husbandry towns,the number of epidemic towns,epidemic villages,per capita net incomes in animal husbandry regions,the total number of livestock and the number of sheep and the prevalence of echinococciasis was positively correlated (r =0.282,0.285,0.387,0.508,0.540,0.317,0.475,0.594,all P ＜0.05);longitude,average annual temperature,annual rainfall,secondary industries,drinking water sources and the prevalence of echinococciasis was negatively correlated (r =-0.311,-0.244,-0.244,-0.389,-0.311,all P ＜0.05).Multiple linear regression analysis showed that differences of interactions of annual rainfalls,drinking water sources,epidemic villages,per capita net incomes of herdsmen,secondary industries and the total number of livestock between groups were statistically significant (t =-1.822,-3.920,3.013,1.715,-1.609,3.264,all P ＜0.05).Conclusion The factors influencing the prevalence of echinococciasis in Gansu Province are correlated with annual rainfalls,drinking water sources,epidemic villages,per capita net incomes of herdsmen,secondary industries and the total number of livestock.

Objective To establish a new rat model of biliary atresia by pure ethanol injection into the common bile duct.Methods A catheter was inserted and fixed in the common bile duct in male SD rats .Saline (8 rats) or pure ethanol (16 rats) was injected through the catheter ,respectively, and the biochemical and pathological changes in the rats were examined .Results SD rats in the experimental group were divided into a persistent injury and a restoration of liver dysfunction groups according to pathological and biochemical detection .In the persistent injury group , biochemical impair-ments were significantly higher at 8 weeks after ethanol injection than those in the control group and restoration group .Dis-tinct pathological changes in the liver were observed using HE , SMA, and Masson staining .Conclusions It is a reliable animal model of biliary atresia induced by injection of pure ethanol into the common bile duct in the rat .It will provide a useful tool in future studies of biliary atresia .

AIM: To investigate the effect of 17? estradiol (17?E 2)on atherosclerosis and hemorrheology in ovariectomized (OVX) rabbits. METHODS: Thirty four female rabbits were divided into 4 groups, group A: normal control; group B: sham+CHO; group C: OVX+CHO; group D: OVX+CHO+17? E 2. Cholesterol(CHO) was fed to rabbits for 12 weeks, before and after feeding CHO, the serum lipid (TC, TG, HDL-C, LDL-C, ApoA1, ApoB) and area of aortic atherosclerotic plaques were measured. Blood viscosity, plasma viscosity (?p), aggregation index of RBC (AIRC) and fibrinogen were also determined, respectively. RESULTS: ① The ratio of area of aortic atherosclerotic plaque to total area of aortic intima was 0.02?0.003 (in group A), 0.42?0.15 (group B), 0.67?0.23 (group C), and 0.12?0 11 (group D), respectively. In group D, the ratio of aortic atherosclerotic plaque was markedly decreased compared with group C ( P
