Objective To investigate the mechanism of Shugan Zhixie Prescription in treating irritable bowel syndrome with diarrhea(IBS-D)using network pharmacology;To validate the findings through in vivo experiments.Methods Active components and potential targets of Shugan Zhixie Prescription were identified via the TCMSP database.Disease targets for IBS-D were retrieved from GeneCards,DisGeNET and OMIM databases.The intersection of drugs and disease targets was taken,and the protein interaction network was constructed by using STRING database.GO and KEGG pathways were enriched to identify the key signaling pathways of Shugan Zhixie Prescription in the treatment of IBS-D.The rat model of liver depression and spleen deficiency type IBS-D was established by the method of abnormal hunger and satiety,restraint pinch stress and intestinal perfusion of acetic acid.The rats were intervened with low-,medium-and high-dosage of Shugan Zhixie Prescription respectively for 14 days.Serum contents of diamine oxidase(DAO),interleukin(IL)-8,and IL-18 were measured by ELISA.Protein expressions and mRNA expressions of relevant targets in colonic tissue were detected using Western blot and RT-qPCR.Results A total of 26 active components and 553 targets of Shugan Zhixie Prescription were obtained,and 1 930 targets of IBS-D disease were obtained,with 184 drug-disease intersection targets.The possible mechanism was related to NF-κB,AGE-RAGE,Th17 cell differentiation and other signaling pathways.Animal experiments demonstrated that Shugan Zhixie Prescription could significantly reduce defecation frequency,fecal water content,and inflammatory cytokine levels in model rats.It markedly decreased TLR4 and NF-κB protein expressions(P<0.01),while increased AQP3,AQP8 and Occludin protein expressions in colonic tissue(P<0.01,P<0.05).Conclusion Shugan Zhixie Prescription exerts therapeutic effects on IBS-D through multiple pathways and targets,and the mechanism may be related to inhibiting TLR4/NF-κB signaling pathway and promoting intestinal barrier repair.

Spleen-stomach damp-heat syndrome is currently the most prevalent TCM pattern in patients with chronic atrophic gastritis (CAG), with internal damp-heat accumulation regarded as a key factor contributing to its prolonged and refractory course. This syndrome represents a critical stage in the progressive pathogenesis of CAG, characterized by a deepening pathological evolution. Modern TCM practitioners generally agree that its core pathogenesis lies in "deficiency in root and excess in superficiality, with internal damp-heat retention", and emphasize a treatment strategy that combines eliminating pathogenic factors and reinforcing the body's healthy qi through dynamic syndrome differentiation. Chinese materia medica used in treating CAG with spleen-stomach damp-heat syndrome can effectively relieve clinical symptoms, improve the internal damp-heat environment, mitigate gastric mucosal atrophy and intestinal metaplasia, and delay the inflammation-to-cancer transformation. Its mechanisms may involve eradication of Helicobacter pylori, repair of gastric mucosal injury, regulation of immune inflammatory response and other aspects, which has the advantages of multi-channel and multi-target.

Objective To perform an economic evaluation of ilaprazole in the treatment of patients with peptic ulcer bleeding and low-risk stigmata,and to provide a reference for drug selection.Methods From a societal perspective,we used decision analysis to evaluate the cost and effectiveness of ilaprazole and omeprazole in treating peptic ulcer bleeding patients dur-ing hospital stays.The probabilities of model nodes were taken from phase Ⅲ clinical trial research results,while cost data came from national medical insurance prices,published literature,and hospital databases.Sensitivity analysis and scenario analysis were performed to test the stability of the results.Results A cost minimization analysis was performed.Under the basic setting,the cost of the ilaprazole group was 4 038.99 yuan,and that of the omeprazole group was 3 837.61 yuan,which means that the cost of the ilaprazole group was 201.38 yuan higher.Sensitivity analysis showed that the results were stable.Scenario analysis showed that ilaprazole was more cost-effective than the innovator drug of omeprazole.Conclusion Ilaprazole was less economical than ome-prazole in the treatment of peptic ulcer bleeding patients with low-risk stigmata.

Objective:Based on the activities of Helicobacter pylori ( HP) screening in Jiangsu Province in 2024, to evaluate the overall management ability in HP screening, testing, treatment and follow-up in primary medical facilities. Methods:From May 15 to October 18, 2024, the data of HP screening and treatment were retrospectively collected from 79 township health centers, community hospitals, and community health service centers in Jiangsu Province. The rates of screening completion, urea breath test (UBT) completion, treatment rate, UBT follow-up completion, and HP eradication were analyzed. Chi-square test was used for statistical analysis. Results:The completion rate of HP screening was 94.45% (15 489/16 400). There were 6 604 cases (42.64%) with serum HP antibody positive among the 15 489 individuals who completed screening. The positive rate of serum HP antibody in males was higher than that in females (44.77%, 2 643/5 904 vs. 41.32%, 3 961/9 585), and the difference was statistically significant ( χ2=17.69, P<0.001). The positive rates of serum HP antibody in screened individuals aged 18 to 19, 20 to 39, 40 to 59, and 60 to 75 years old were 22.38% (32/143), 36.12% (1 168/3 234), 45.01% (3 240/7 199), and 44.05% (2 164/4 913), respectively, and the difference was statistically significant( χ2=100.73, P<0.001). Among the 6 604 HP antibody-positive individuals, 4 381 cases completed UBT, with a UBT completion rate of 66.34% (4 381/6 604). There were 3 197 individuals with both HP serum antibody and UBT positive, the consistency rate of the 2 tests was 72.97% (3 197/4 381). Totally 2 737 cases received treatment, with a treatment completion rate of 85.61% (2 737/3 197); 2 327 individuals underwent UBT follow-up, with a follow-up completion rate of 85.02% (2 327/2 737). During follow-up, the result of UBT was negative in 1 982 individuals, and the HP eradication rate was 85.17% (1 982/2 327). Conclusions:There are deficiencies in the completion rate of HP screening, testing, treatment, and follow-up in primary hospitals, especially in the completion rate of UBT, which may be related to cognitive insufficiency for HP in residents. It is necessary to strengthen the training of physicians′ abilities in primary hospitals, optimize the allocation of drug resources, enhance health education, and increase residents′ participation and compliance.

Objective:To investigate the correlation between insulin resistance surrogate indicators and early-stage kidney injury in type 2 diabetes mellitus(T2DM).Methods:A total of 918 T2DM patients hospitalized in the Endocrinology Department of Xinhua Hospital from January 2018 to December 2020 were selected, including 313 patients with early-stage kidney injury and 605 without. Differences in insulin resistance surrogate indicators, including triglyceride to high-density lipoprotein cholesterol ratio(TG/HDL-C), triglyceride glucose(TyG) index, and triglyceride glucose-body mass index(TyG-BMI), were compared between the two groups. Factors associated with early-stage kidney injury in T2DM were analyzed, and the impact of TG/HDL-C, TyG index, and TyG-BMI on early-stage kidney injury in T2DM were explored.Results:Compared with T2DM patients without early-stage kidney injury, those with early-stage kidney injury exhibited significantly elevated levels of TG/HDL-C, TyG index, and TyG-BMI( P< 0.001). TG/HDL-C, TyG index, TyG-BMI, age, duration of diabetes, systolic blood pressure, fasting insulin, and HbA 1C were identified as independent risk factors for early-stage kidney injury in T2DM. Compared to the Q1 quartile, the risk in the Q4 quartile was 3.168 times(95% CI 1.993-5.036) for TG/HDL-C, 2.714 times(95% CI 1.710-4.306) for TyG index, and 2.893 times(95% CI 1.820-5.598) for TyG-BMI. Conclusion:Insulin resistance surrogate indicators TG/HDL-C, TyG index, and TyG-BMI are significantly elevated in T2DM patients with early-stage kidney injury, serving as independent risk factors for early-stage renal impairment in T2DM.

Objective:To compare the efficacy and safety of irradiation-incorporated and chemotherapy only-based myeloablative conditioning regimens in haploidentical hematopoietic stem cell transplantation (haplo-HSCT) for patients with high-risk myeloid malignancies.Methods:This study retrospectively collected clinical data from 63 high-risk acute myeloid leukemia/myelodysplastic syndrome (AML/MDS) patients who underwent haplo-HSCT at the Fifth Medical Center of the Chinese PLA General Hospital from January 2015 to December 2019. These patients were classified into the irradiation ( n = 17) and chemotherapy ( n = 46) groups based on different conditioning regimens. The differences between the two groups were compared in terms of hematopoietic reconstitution, cumulative incidence of acute/chronic graft-versus-host diseases (aGVHD and cGVHD), non-relapse mortality (NRM), relapse rate (RR), overall survival (OS), and disease-free survival (DFS), followed by the analysis of prognostic factors. Results:The median follow-up time for the irradiation and chemotherapy groups was 78.5 and 72.3 months, respectively. The median time for neutrophil engraftment was 14.0 days in the irradiation group and 14.5 d in the chemotherapy group, and for platelet engraftment was 15.0 and 13.0 d, respectively. As a result, the two groups showed no statistically significant differences in hematopoietic reconstitution ( P > 0.05). The cumulative incidence of aGVHD and cGVHD was higher in the irradiation group compared to the chemotherapy group, yet showing no statistically significant differences ( P > 0.05). Specifically, the cumulative incidence of grade Ⅱ-Ⅳ aGVHD within 100 d was 29.4% and 21.7% for the irradiation and chemotherapy groups, respectively. The cumulative incidence of grade Ⅲ-Ⅳ aGVHD was 23.5% and 13.0%, respectively. The cumulative incidence of severe cGVHD within five years was 11.8% in the irradiation group and 8.7% in the chemotherapy group. In terms of long-term survival, the cumulative 5\|year RR and NRM were 20.2% and 28.4% in the irradiation group, 5.9% and 23.9% in the chemotherapy group, respectively, showing no statistically significant differences ( P > 0.05). The 5-year DFS and OS rates were 73.9% and 47.7% in the irradiation group, and 81.1% and 54.4% in the chemotherapy group, respectively, without statistically significant differences ( P > 0.05). Notably, the irradiation group manifested more favorable DFS and OS survival curves compared to the chemotherapy group. The survival curves indicate that the irradiation-incorporated regimen exhibited better trends in OS, DFS, and cGVHD-free relapse-free survival (GRFS). However, multivariate analysis did not reveal that irradiation conditioning is an independent prognostic factor affecting survival [ HR = 0.532 (0.163-1.735), 0.370 (0.091-1.516), 0.683 (0.248-1.882), P > 0.05]. Conclusions:In haplo-HSCT for high-risk myeloid malignancies, the irradiation-incorporated conditioning regimen demonstrates lower RR and NRM, higher DFS and OS, and potentially superior survival outcomes compared to the chemotherapy only-based regimen. Therefore, the irradiation-incorporated conditioning regimen may be preferentially considered in haplo-HSCT.
