ABSTRACT
BACKGROUND: The incidence of diabetic gastrointestinal diseases is increasing year by year. This study aimed to investigate the causal relationship between antidiabetic medications and gastrointestinal disorders, with the goal of reducing the incidence of diabetes-related gastrointestinal diseases and exploring the potential repurposing of antidiabetic drugs. METHODS: We employed a two-sample Mendelian randomization (TSMR) design to investigate the causal association between antidiabetic medications and gastrointestinal disorders, including gastroesophageal reflux disease (GERD), gastric ulcer (GU), chronic gastritis, acute gastritis, Helicobacter pylori infection, gastric cancer (GC), functional dyspepsia (FD), irritable bowel syndrome (IBS), ulcerative colitis (UC), Crohn's disease (CD), diverticulosis, and colorectal cancer (CRC). To identify potential inhibitors of antidiabetic drug targets, we collected single-nucleotide polymorphisms (SNPs) associated with metformin, GLP-1 receptor agonists, SGLT2 inhibitors, DPP-4 inhibitors, insulin, and its analogs, thiazolidinediones, sulfonylureas, and alpha-glucosidase inhibitors from published genome-wide association study statistics. We then conducted a drug-target Mendelian randomization (MR) analysis using inverse variance weighting (IVW) as the primary analytical method to assess the impact of these inhibitors on gastrointestinal disorders. Additionally, diabetes was selected as a positive control. RESULTS: Sulfonylureas were found to significantly reduce the risk of CD (IVW: OR [95% CI] = 0.986 [0.978, 0.995], p = 1.99 × 10- 3), GERD (IVW: OR [95% CI] = 0.649 [0.452, 0.932], p = 1.90 × 10- 2), and chronic gastritis (IVW: OR [95% CI] = 0.991 [0.982, 0.999], p = 4.50 × 10- 2). However, they were associated with an increased risk of GU development (IVW: OR [95%CI] = 2 0.761 [1.259, 6.057], p = 1 0.12 × 10- 2). CONCLUSIONS: The results indicated that sulfonylureas had a positive effect on the prevention of CD, GERD, and chronic gastritis but a negative effect on the development of gastric ulcers. However, our research found no causal evidence for the impact of metformin, GLP-1 agonists, SGLT2 inhibitors, DPP 4 inhibitors, insulin and its analogs, thiazolidinediones, or alpha-glucosidase inhibitors on gastrointestinal diseases.
ABSTRACT
OBJECTIVES: To compare the clinical effect between inverted T-shaped herb-separated moxibustion combined with western medication and simple western medication on chronic pelvic pain(CPP)in sequelae of pelvic inflammatory diseases. METHODS: A total of 60 patients with CPP in sequelae of pelvic inflammatory diseases were randomly divided into an observation group and a control group, 30 cases in each group. The control group was given ibuprofen tablets 10 days before menstruation, 0.2 g each time, once a day for 10 days. After menstruation, the medication was stopped, and the treatment was given for 3 menstrual cycles.On the basis of the treatment in the control group, the observation group was treated with inverted T-shaped herb-separated moxibustion at the connection between Zhongwan(CV 12)and Zhongji(CV 3), and the connection between Zigong(EX-CA 1)on both sides.The treatment was performed once a week, with an interval of 6 days. The moxibustion was stopped during the menstrual period, the treatment was given for 3 menstrual cycles.Before and after treatment, the visual analogue scale(VAS)score of lower abdominal and lumbosacral pain, local symptom (uterine tenderness, adnexal tenderness and uterosacral ligament tenderness) score and quality of life assessment (QOL) score of the two groups were observed. RESULTS: After treatment, the lower abdominal and lumbosacral pain VAS scores, the local symptom scores of uterine tenderness, adnexal tenderness, uterosacral ligament tenderness and total scores in the two groups were lower than those before treatment(P<0.01).The lower abdominal and lumbosacral pain VAS score in the observation group was lower than that in the control group(P<0.01),and the changes of local symptom scores of uterine tenderness, adnexal tenderness and uterosacral ligament tenderness and total score in the observation group were greater than those in the control group(P<0.01). After treatment, the QOL scores of the two groups were higher than those before treatment(P<0.01), and the score in the observation group was higher than that in the control group(P<0.01). CONCLUSIONS: Inverted T-shaped herb-separated moxibustion combined with western medication can effectively reduce the pain in patients with CPP in sequelae of pelvic inflammatory diseases, relieve the local symptoms, improve the quality of life, and the curative effect is better than western medication alone.

Intraguild predation is a common ecological phenomenon that manifests itself by the aggression of one predator by another to obtain a shared prey species. In this paper, we develop a discrete analog of a stoichiometric continuous-time intraguild predation model. We analyze the dynamics of the discrete-time model, such as boundedness and invariance, stability of equilibria, and features of ecological matrices. The dynamic behavior of the two models is compared and analyzed through numerical analysis. We observe the same coexistence region of populations and stoichiometric effects of food quality of the shared prey in both models. Obvious differences between the discrete- and continuous-time models can be observed with intermediate and high levels of light intensity. The multistability characteristics and the existence interval of chaos differ among the different time scale models. This study provides evidence of the importance of time scales on intraguild predation.
