TCM believes that the main pathogenesis of gastrointestinal dysfunction (GD) after laparoscopic cholecystectomy (LC) is spleen and stomach weakness, liver and stomach disharmony, liver depression and spleen deficiency, and intestinal depression. Moxibustion in the treatment of GD after LC can avoid the aggravation of gastrointestinal burden caused by oral drugs. The intervention methods mainly include suspension moxibustion, umbilical moxibustion, heat sensitive moxibustion, thunder fire moxibustion, warm acupuncture, partition moxibustion, etc. Moxibustion is often performed on the acupoints in liver meridian, spleen meridian, stomach meridian, small intestine meridian, large intestine meridian and Conception Vessel, such as Taichong (LR3), Ganshu (BL18), Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), Wangu (SI4), Hegu (LI4), Zhongwan (CV12), Shenque (CV8) and Qihai (CV6). At present, most studies combined with moxibustion on the basis of conventional Western medicine treatment can significantly improve the efficacy, and have certain advantages in improving gastrointestinal motility decline, intestinal flora imbalance, first exhaust time, gastrointestinal hormone level disorder and intestinal mucosal barrier dysfunction. However, there are still some problems in the existing research: small sample size of clinical research, not perfect scoring scale, not unified treatment plan and operation standard, relatively scarce basic research, relatively simple acupoint research, lack of biochemical evaluation indicators, and the research of national moxibustion needs to be explored and improved in the future.

Objective:To explore the current situation of the intrinsic capacity of elderly people in the community and analyze its influencing factors.Methods:From September 2022 to March 2023, convenience sampling was used to select 360 elderly community residents from Xicheng District, Beijing, and Xingtai City, Hebei Province, as the research subjects. The subjects were surveyed using the Intrinsic Capacity Assessment Questionnaire, Intrinsic Capacity Influencing Factors Questionnaire, Barthel Index, and Lawton Instrumental Activities of Daily Living Scale.Results:A total of 360 questionnaires were distributed, and 360 valid questionnaires were collected, with an effective response rate of 100.0% (360/360). The overall impairment rate of intrinsic capacity among 360 elderly people in the community was 90.3% (325/360), and the impairment rates in various fields from high to low were sensation, psychology, vitality, cognition, and exercise. Multiple linear regression analysis showed that age, gender, residential pattern, education level, work status, grip strength, number of geriatric syndrome, self-rated health status, adverse life events, number of social activities, transportation conditions, and social security were the influencing factors of the intrinsic capacity of elderly people in the community, and the difference was statistically significant ( P<0.05) . Conclusions:The impairment rate of intrinsic capacity among elderly people in the community is relatively high. Grassroots medical and nursing staff should assess the intrinsic capacity of elderly people in the community in health promotion work, identify elderly people with decreased intrinsic capacity early and carry out effective interventions to prevent elderly people from becoming disabled and dependent on care.

Objective:To explore the influencing factors for hypoglycemia in elderly patients during peri-colonoscopy, construct and validate a risk prediction model.Methods:The factors influencing hypoglycemia in elderly patients during the peri-colonoscopy period were identified through a literature review and semi-structured interviews. After two rounds of Delphi expert consultation, the survey questionnaire was determined. From January to September 2023, convenience sampling was used to select elderly patients who underwent colonoscopy in the Department of Gastroenterology at the Affiliated Hospital of Qingdao University as participants for a questionnaire survey. Univariate and multivariate Logistic regression was used to explore the influencing factors of hypoglycemia in elderly patients during the peri-colonoscopy period, and a nomogram model of hypoglycemia risk in elderly patients during the peri-colonoscopy period was drawn. The area under the receiver operating characteristic curve ( AUC) of the subjects and the Hosmer-Lemeshow goodness of fit test were used to evaluate the model's predictive performance. The clinical decision curve of DCA was implemented to evaluate the model's clinical benefit ability. Results:A total of 558 questionnaires were distributed (392 for the modeling group and 166 for the validation group) and 558 valid questionnaires were collected, with a valid response rate of 100.00%. Among 558 elderly patients, a total of 130 cases (89 in the modeling group and 41 in the validation group) experienced hypoglycemia during the peri-colonoscopy period, with an incidence of 23.30%. Multivariate Logistic regression analysis showed that serum albumin, age, previous hypoglycemia frequency, insulin use, fasting time, and nutritional risk were independent influencing factors (all P<0.05). The AUCs of the modeling and validation groups were 0.933 and 0.899, respectively. Hosmer Lemeshow test showed that the model had good calibration accuracy, and the DCA curve indicated that the model had good clinical effectiveness. Conclusions:The nomogram model has good predictive performance and can intuitively and concisely predict the risk of hypoglycemia in elderly patients during the peri-colonoscopy period, providing reference for medical and nursing staff.

Objective To explore the effects and mechanism of Baitouweng Decoction in intestinal mucosal healing in mice with ulcerative colitis(UC)based on RIPK1/RIPK3/MLKL signaling pathway.Methods Totally 30 C57BL/6 male mice were randomly divided into control group,model group,Baitouweng Decoction group,infliximab group and combination group(Baitouweng Decoction+infliximab),with 6 mice in each group.A mouse model of UC was established by free administration of 3.5%sodium gluconate sulfate solution for 7 days.After modeling,Baitouweng Decoction group was given 8 g/kg Baitouweng Decoction solution by gavage daily,while the infliximab group was given 5 mg/kg infliximab intraperitoneal injection,the combination group was given synchronous gastric and intraperitoneal injection,while the control group and model group were given equal volume of normal saline by gavage for 7 consecutive days.The body mass of mice was recorded daily,fecal characteristics were observed,and disease activity index(DAI)score was performed,colon length was measured after intervention,ELISA was used to detect the contents of serum interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α),RT-qPCR was used to detect mRNA expressions of RIPK1,RIPK3 and MLKL in colon tissue,Western blot and immunofluorescence staining were used to detect the expressions of RIPK1,RIPK3 and MLKL protein in colon tissue.Results Compared with the control group,the model group mice showed a decrease in body mass(P<0.01),an increase in DAI score(P<0.01),a shortened colon length(P<0.01),and an increase in serum IL-6 and TNF-α content(P<0.01);colonic mucosal was destructed,with disappearance of crypts and glandular structures,extensive infiltration of inflammatory cells,and increased pathological score of colon tissue(P<0.01);the mRNA and protein expressions of RIPK1,RIPK3 and MLKL in colon tissue increased(P<0.01,P<0.05).Compared with the model group,the body mass of mice in each treatment group increased(P<0.01),and the DAI score decreased(P<0.01),colon length increased(P<0.01),and the contents of serum IL-6 and TNF-α decreased(P<0.05,P<0.01);the destruction of the colonic mucosal barrier was reduced,the pathological score of colon tissue was reduced(P<0.05);the expressions of RIPK1,RIPK3 and MLKL mRNA and protein in colon tissue decreased(P<0.05,P<0.01).Conclusion Baitouweng Decoction can alleviate intestinal mucosal damage and inflammation in UC mice,and its mechanism may be related to the inhibition of the RIPK1/RIPK3/MLKL signaling pathway.

Objective To investigate the effects of formononetin (FMN) on cognitive behavior and inflammation in aging rats with chronic unpredictable mild stress (CUMS). Methods SD rats aged about 70 weeks were divided into healthy control group, CUMS model group, CUMS combined with 10 mg/kg FMN group, CUMS combined with 20 mg/kg FMN group and CUMS combined with 1.8 mg/kg fluoxetine hydrochloride (Flu) group. Except for healthy control group, other groups were stimulated with CUMS and administered drugs for 28 days. Sugar water preference, forced swimming experiment and open field experiment were used to observe the emotional behavior of rats in each group. HE staining was used to observe the pathological injury degree of brain equine area. The contents of 5-hydroxytryptamine (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) were detected by the kit. The apoptosis was tested by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) in the brain tissue. The levels of tumor necrosis factor α (TNF-α), inducible nitric oxide synthase (iNOS) and interleukin 6 (IL-6) in peripheral blood were measured by ELISA. Western blot analysis was used to detect Bcl2, Bcl2 associated X protein (BAX), cleaved caspase-9, cleaved caspase-3, Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), and phosphorylated nuclear factor κB p65 (p-NF-κB p65) in brain tissues. Results Compared with CUMS model group, sugar water consumption, open field activity time, open field travel distance and swimming activity time significantly increased in the CUMS combined with 20 mg/kg FMN group and the CUMS combined with 1.8 mg/kg Flu group. The number of new outarm entry increased significantly, while the number of initial arm entry and other arm entry decreased significantly. The pathological damage of brain equine area was alleviated, and the contents of 5-HT and 5-HIAA were significantly increased. The ratio of BAX/Bcl2 and the expression of cleaved caspase-9 and cleaved caspase-3 protein as well as the number of apoptotic cells were significantly decreased. The contents of TNF-α, iNOS and IL-6 were significantly decreased. The protein levels of TLR4, MyD88 and p-NF-κB p65 were significantly decreased. Conclusion FMN can inhibit the release of inflammatory factors by blocking NF-κB pathway and improve cognitive and behavioral ability of CUMS aged rats.
