OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland （HMG）. METHODS Female SD rats were divided into control group and HMG group according to body weight， with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling， two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid （calculated by crude drug） intragastrically， once a day， for 7 consecutive days. Blood samples were collected before the first administration （0 h）， and at 5， 15， 30 minutes and 1， 2， 4， 8， 12， 24 hours after the last administration， respectively. Using chlorzoxazone as the internal standard， the plasma concentrations of ferulic acid， paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve （AUC0－24 h， AUC0－∞）， mean residence time （MRT0－∞）， half-life （t1/2）， peak time （tmax）， peak concentration （cmax）] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group， the AUC0－24 h， AUC0－∞ and cmax of ferulic acid in the HMG group were significantly increased （P＜0.05）； the AUC0－24 h， AUC0－∞ ， MRT0－∞ ， t1/2 and cmax of paeoniflorin increased， but there was no significant difference between 2 groups （P＞0.05）； the AUC0－24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged （P＜0.05）. C ONCLUSIONS In HMG model rats， the exposure of ferulic acid， paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase， and the retention time of rosmarinic acid is significantly prolonged.

Background and Aims:Whether to close mesenteric fissures during laparoscopic radical resection of colorectal cancer remains controversial.Traditional suture closure is technically demanding and may injure mesenteric vessels.This study aimed to evaluate the safety and efficacy of using α-cyanoacrylate medical glue to close mesenteric fissures during laparoscopic colorectal cancer surgery.Methods:A retrospective analysis was conducted on patients who underwent laparoscopic radical resection of colorectal cancer in the Department of Colorectal Surgery,the Sixth Affiliated Hospital of Sun Yat-sen University,from January 2022 to December 2023.Seventy-eight patients who received intraoperative α-cyanoacrylate glue closure of mesenteric fissures were included as the observation group,and 74 patients without fissure closure were selected as the control group using the propensity score matching method.Perioperative parameters,postoperative recovery,and complications were compared between the two groups.Results:No significant differences were observed in baseline characteristics or main intraoperative variables between groups(all P>0.05).The observation group had significantly less ascitic drainage within 3 days after operation[(203.14±116.44)mL vs.(384.53±243.89)mL,P<0.01]and shorter postoperative gas passage,defecation,and drainage tube removal times(all P<0.01).The incidence of postoperative complications and intestinal obstruction was comparable between groups(all P>0.05).Multivariate analysis showed that intraoperative application of α-cyanoacrylate glue was an independent promoting factor for intestinal exhaust within 3 days after surgery(OR=5.739,P=0.000).Conclusion:The use of α-cyanoacrylate medical glue for closing mesenteric fissures during laparoscopic radical resection of colorectal cancer is safe and feasible.It effectively reduces postoperative ascitic drainage and accelerates bowel recovery,offering a simple and reliable alternative to traditional suture closure.

In the IC fingerprint, there was significant difference in the "peak area/weight" values of peak 1 between mixed decoction and single decoction with different compatibility ratios (1:1, 3:2, 2:1, 5:2, 3:1) ( P<0.05), while there was no significant difference in peak 5 (calcium ion) ( P>0.05). Conclusion:There are differences in the chemical component content of Gypsum Fibrosum-Anemarrhenae Rhizoma medicinal pair for single decoction and mixed decoction.

Objective:To investigate epidemiological characteristics of Mycobacterium marinum infection cases in the Dermatology Hospital of Shandong First Medical University from January 2019 to December 2021. Methods:Data were collected from patients with Mycobacterium marinum infection in the Dermatology Hospital of Shandong First Medical University from January 2019 to December 2021. Demographic characteristics, clinical features and prognosis of patients were retrospectively analyzed. Differences between groups were analyzed using t test, Chi-square test and Fisher′s exact test; factors influencing the time to diagnosis (the time from the first appearance of skin manifestations to the diagnosis of Mycobacterium marinum infection in the hospital) longer than 12 months were analyzed using Chi-square test and multivariate logistic regression model, and the odds ratio ( OR) and 95% confidence interval (95% CI) were calculated. Results:From 2019 to 2021, a total of 373 cases of Mycobacterium marinum infection were diagnosed in the hospital, and the number of cases in 2021 was 4.06 times that in 2019; the male-to-female ratio was 1∶1.49, and their age was 54.24 ± 14.04 years. Among the 373 patients, 211 (56.57%) had a history of trauma caused by aquatic products (e.g., fishes, shrimps), of which 51 (24.17%) were stung by sea perch. Skin lesions involved unilateral limbs in 327 (87.67%) patients, only involved the hands or wrists in 188 (50.40%) patients, and 258 (69.17%) had multiple skin lesions. Among the 341 patients with treatment information, 105 (30.79%) were given one antibiotic, 214 (62.76%) received combination treatment with two antibiotics, and 15 (4.40%) were treated with three antibiotics. The response rate was 98.77% (321/325), and the time to diagnosis [ M ( Q1, Q3) ] was 5.03 (3.00, 8.37) months. Multivariate logistic regression analysis indicated higher proportions of males ( OR [95% CI]: 1.95[1.11 - 3.41], P = 0.02), patients aged > 55 years ( OR [95% CI]: 1.82[1.04 - 3.18], P = 0.04), patients with skin lesions only involving hands, arms or lower limbs ( OR [95% CI]: 3.48[1.83 - 6.61], P<0.001) among the patients whose time to diagnosis was longer than 12 months. Conclusions:The number of patients with Mycobacterium marinum infection was increased in the Dermatology Hospital of Shandong First Medical University year by year from 2019 to 2021, and fish sting wounds were the main cause of infection. The most common treatment regimen was the combination of two antibiotics, with a high efficacy profile.

Behçet’s syndrome is a kind of chronic systemic vasculitis with involvement of multiple organs. Intestinal involvement of Behçet’s syndrome is presently named as intestinal Behçet’s syndrome (disease). Recently, there is considering another kind of disease type with only typical intestinal ulcers. Since it is difficult to differentiate intestinal Behçet’s syndrome from Crohn’s disease, intestinal tuberculosis, intestinal lymphoma, as well as intestinal manifestations of many other autoimmune diseases, and there is limited evidence for the therapy of intestinal Behçet’s syndrome, proposing diagnosis and treatment recommendations for intestinal Behçet’s syndrome through evidence-based judgment will be of great significance for clinical practice.

ObjectiveTo explore the effects of anxiety and depression on Internet gaming disorder in medical students， and to evaluate the moderating effect of gender， so as to provide references for the prevention and intervention of Internet gaming disorder in medical students. MethodsIn November 2021， a total of 11 771 medical students from a medical college in Sichuan province participated in an online survey through Wenjuanxing platform. Participants completed the Self-rating Anxiety Scale （SAS）， Self-rating Depression Scale （SDS） and the nine-item Internet Gaming Disorder Scale-Short Form （IGDS9-SF）. Then a hierarchical multiple regression analysis was conducted to discuss the moderating role of gender in the relationships between anxiety， depression and Internet gaming disorder in medical students. Results①Males scored lower on SDS （t=-8.302， P<0.01）， and higher on IGDS9-SF than females （t=33.384， P<0.01）. ②SAS score of medical students was positively correlated with SDS score （r=0.735， P<0.01）， SAS and SDS scores were positively correlated with IGDS9-SF score in medical students （r=0.288， 0.238， P<0.01）. ③Anxiety and depression could positively predict Internet gaming disorder （β=0.245， 0.058， t=18.864， 4.444， P<0.01）. ④Gender played a moderating effect between anxiety and Internet gaming disorder （β=-0.194， t=-4.518， P<0.01）. ConclusionAnxiety and depression have a positive predictive effect on Internet gaming disorder in medical students. Furthermore， the effects of anxiety on Internet gaming disorder are moderated by gender， and the anxiety of male students exhibits a markedly stronger impact on Internet gaming disorder than that of female students.

ObjectiveTo evaluate the effects of high intensity interval training (HIIT) on patients with type 2 diabetes mellitus (T2DM). MethodsFrom May to October, 2021, twelve patients with T2DM were recruited with internet. An HIIT exercise intervention based on WHO Guidelines on Physical Activity and Sedentary Behaviour and World Health Organization Family of International Classifications (WHO-FICs) was constructed. They received aerobic combined with resistance training in a multi-combination HIIT using whole-body exercise, 30 to 35 minutes a time, three times a week, for eight weeks. Before and after intervention, their blood glucose levels, lipid levels, pancreatic fat content and body composition were measured. ResultsOne cased was dropped. After intervention, the fasting glucose, 2-hour postprandial glucose, hemoglobin A1c, fasting serum insulin, insulin resistance index, serum total cholesterol, serum triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, pancreatic fat content, body weight, body mass index, and body fat percentage improved (t > 2.258, P < 0.05). ConclusionHIIT exercise intervention based on the Guidelines and WHO-FICs could improve the related functions of patients with T2DM, such as blood glucose levels, blood lipid levels, pancreatic fat content and body composition, and reduce the consumption of hypoglycemic drugs.
