The gut microbiota regulates intestinal nutrient absorption, participates in modulating host glucolipid metabolism, and contributes to ameliorating glucolipid metabolism disorder. Dysbiosis of the gut microbiota can compromise the integrity of the intestinal mucosal barrier, induce inflammatory responses, and exacerbate insulin resistance and abnormal lipid metabolism in the host. Dangua Humai Oral Liquid, a hospital-developed formulation for regulating glucolipid metabolism, has been granted a national invention patent and demonstrates significant clinical efficacy. This study aimed to investigate the effects of Dangua Humai Oral Liquid on gut microbiota and the intestinal mucosal barrier in a mouse model with glucolipid metabolism disorder. A glucolipid metabolism disorder model was established by feeding mice a high-glucose and high-fat diet. The mice were divided into a normal group, a model group, and a treatment group, with eight mice in each group. The treatment group received a daily gavage of Dangua Humai Oral Liquid(20 g·kg~(-1)), while the normal group and model group were given an equivalent volume of sterile water. After 15 weeks of intervention, glucolipid metabolism, intestinal mucosal barrier function, and inflammatory responses were evaluated. Metagenomics and untargeted metabolomics were employed to analyze changes in gut microbiota and associated metabolic pathways. Significant differences were observed between the indicators of the normal group and the model group. Compared with the model group, the treatment group exhibited marked improvements in glucolipid metabolism disorder, alleviated pathological damage in the liver and small intestine tissue, elevated expression of recombinant claudin 1(CLDN1), occluding(OCLN), and zonula occludens 1(ZO-1) in the small intestine tissue, and reduced serum levels of inflammatory factors lipopolysaccharides(LPS), lipopolysaccharide-binding protein(LBP), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α). At the phylum level, the relative abundance of Bacteroidota decreased, while that of Firmicutes increased. Lipid-related metabolic pathways were significantly altered. In conclusion, based on the successful establishment of the mouse model of glucolipid metabolism disorder, this study confirmed that Dangua Humai Oral Liquid effectively modulates gut microbiota and mucosal barrier function, reduces serum inflammatory factor levels, and regulates lipid-related metabolic pathways, thereby ameliorating glucolipid metabolism disorder.

Objective The leptin receptor,encoded by the LEPR gene,is involved in tumorigenesis.A potential functional variant of LEPR,rs1137101(Gln223Arg),has been extensively investigated for its contribution to the risk of digestive system(DS)cancers,but results remain conflicting rather than conclusive.Here,we performed a case-control study and subsequent meta-analysis to examine the association between rs1137101 and DS cancer risk. Methods A total of 1,727 patients with cancer(gastric/liver/colorectal:460/480/787)and 800 healthy controls were recruited.Genotyping of rs1137101 was conducted using a polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)assay and confirmed using Sanger sequencing.Twenty-four eligible studies were included in the meta-analysis. Results After Bonferroni correction,the case-control study revealed that rs1137101 was significantly associated with the risk of liver cancer in the Hubei Chinese population.The meta-analysis suggested that rs1137101 is significantly associated with the risk of overall DS,gastric,and liver cancer in the Chinese population. Conclusion The LEPR rs1137101 variant may be a genetic biomarker for susceptibility to DS cancers(especially liver and gastric cancer)in the Chinese population.

Objective:In thyroid surgery,evaluating the combination of near-infrared auto-fluorescence imaging(NIRAF)with injection of mitoxantrone hydrochloride(MHI)as a tracer to en-hance the identification rate of parathyroid glands,thereby reducing the occurrence of post-thyroidectomy hypocalcemia and parathyroid dysfunction.Methods:A prospective study was conducted from October 2022 to March 2023 at Yidu Central Hospital in Weifang City,involving 80 patients undergoing thyroid surgery.Patients were randomly divided into a combined group and a control group based on their admission time,with 40 patients in each group.In the combined group,0.6 mL of mitoxantrone hydrochloride(MHI)was injected into the thyroid gland during sur-gery,and near-infrared autofluorescence(NIRAF)was used for parathyroid gland identification.The control group only used NIRAF during surgery.Compared the preoperative levels of serum calcium and parathyroid hormone(PTH)between the two groups,as well as the intraoperative accuracy of parathyroid gland identification and the rate of autotransplantation.Postoperatively,the study ana-lyzed PTH levels,blood calcium levels,the rate of inadvertent parathyroidectomy,and the inci-dence of hypocalcemia symptoms.Results:In the combined group,there were 4 cases(10.0％)of parathyroid transplantation,compared to 12 cases(30.0％)in the control group,with a statisti-cally significant difference between the two groups(x2=3.828,P=0.049).The accuracy of parathy-roid gland identification in the combined group was higher than that in the control group(x2=3.899,P=0.048).Additionally,there were 2 cases(5.0％)of inadvertent parathyroidectomy in the com-bined group compared to 10 cases(25.0％)in the control group,with a statistically significant dif-ference between the two groups(x2=4.804,P=0.028).Postoperatively at day 1,the blood calcium levels were(2.24±0.11)mmol/L in the combined group and(2.16±0.17)mmol/L in the control group,and the PTH levels were(27.18±11.77)ng/L in the combined group and(18.57±9.55)ng/L in the control group,with statistically significant differences(P＜0.05)observed in both parameters.At day 3 postoperatively,the blood calcium levels were(2.32±0.17)mmol/L in the combined group and(2.23±0.12)mmol/L in the control group;the PTH levels were(33.03±7.88)ng/L in the com-bined group and(24.89±9.29)ng/L in the control group,with statistically significant differences(P＜0.05)observed in both parameters.After surgery,3 cases(7.5％)of numbness in the extremities or around the mouth were observed in the combined group compared to 10 cases(25.0％)in the con-trol group,with a statistically significant difference(P=0.034).Conclusion:The use of NIRAF combined with MHI can effectively improve the accuracy of parathyroid gland identification during thyroid surgery,thereby avoiding inadvertent removal,reducing the occurrence of postoperative hypocalcemia and parathyroid dysfunction,lowering the incidence of postoperative numbness in the extremities or around the mouth,and enhancing the overall patient experience.

The 3-succinate-30-stearyl glycyrrhetinic acid(18-GA-Suc) was inserted into glycyrrhetinic acid(GA)-tanshinone Ⅱ_A(TSN)-salvianolic acid B(Sal B) liposome(GTS-lip) to prepare liver targeting compound liposome(Suc-GTS-lip) mediated by GA receptors. Next, pharmacokinetics and tissue distribution of Suc-GTS-lip and GTS-lip were compared by UPLC, and in vivo imaging tracking of Suc-GTS-lip was conducted. The authors investigated the effect of Suc-GTS-lip on the proliferation inhibition of hepatic stellate cells(HSC) and explored their molecular mechanism of improving liver fibrosis. Pharmacokinetic results showed that the AUC_(Sal B) decreased from(636.06±27.73) μg·h·mL~(-1) to(550.39±12.34) μg·h·mL~(-1), and the AUC_(TSN) decreased from(1.08±0.72) μg·h·mL~(-1) to(0.65±0.04) μg·h·mL~(-1), but the AUC_(GA) increased from(43.64±3.10) μg·h·mL~(-1) to(96.21±3.75) μg·h·mL~(-1). The results of tissue distribution showed that the AUC_(Sal B) and C_(max) of Sal B in the liver of the Suc-GTS-lip group were 10.21 and 4.44 times those of the GTS-lip group, respectively. The liver targeting efficiency of Sal B, TSN, and GA in the Suc-GTS-lip group was 40.66%, 3.06%, and 22.08%, respectively. In vivo imaging studies showed that the modified liposomes tended to accumulate in the liver. MTT results showed that Suc-GTS-lip could significantly inhibit the proliferation of HSC, and RT-PCR results showed that the expression of MMP-1 was significantly increased in all groups, but that of TIMP-1 and TIMP-2 was significantly decreased. The mRNA expressions of collagen-I and collagen-Ⅲ were significantly decreased in all groups. The experimental results showed that Suc-GTS-lip had liver targeting, and it could inhibit the proliferation of HSC and induce their apoptosis, which provided the experimental basis for the targeted treatment of liver fibrosis by Suc-GTS-lip.

This study aimed to explore the correlation between traditional Chinese medicine(TCM) and reduced risk of readmission in patients having rheumatoid arthritis with hypoproteinemia(RA-H). A retrospective cohort study was conducted on 2 437 rheumatoid arthritis patients in the information system database of the First Affiliated Hospital of Anhui University of Chinese Medicine from 2014 to 2021, and 476 of them were found to have hypoproteinemia. The patients were divided into TCM users and non-TCM users by propensity score matching. Exposure was defined as the use of oral Chinese patent medicine or herbal decoction for ≥1 month. Cox regression analysis was performed to explore the risk factors of clinical indicators of rheumatoid arthritis. Additionally, the use of TCM during hospitalization was analyzed, and analysis of association rules was conducted to investigate the correlation between TCM, improvement of indicators and readmission of patients. Kaplan-Meier survival curve was plotted to compare the readmission rate of TCM users and non-TCM users. It was found the readmission rate of RA-H patients was significantly higher than that of RA patients. By propensity score matching, 232 RA-H patients were divided into TCM group(116 cases) and non-TCM group(116 cases). Compared with the conditions in the non-TCM group, the readmission rate of the TCM group was lowered(P<0.01), and the readmission rate of middle-aged and elderly patients was higher than that of young patients(P<0.01). Old age was a risk factor for readmission of RA-H patients, while TCM, albumin(ALB) and total protein(TP) were the protective factors. During hospitalization, the TCMs used for RA-H patients were mainly divided into types of activating blood and resolving stasis, relaxing sinew and dredging collaterals, clearing heat and detoxifying, and invigorating spleen and resolving dampness. The improvement of rheumatoid factor(RF), immunoglobulin G(IgG), erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) and ALB was closely related to TCM. On the basis of western medicine treatment, the application of TCM could reduce the readmission rate of RA-H patients, and longer use of TCM indicated lower readmission rate.

OBJECTIVE: To investigate the expression level of miR-342-3p in peripheral blood mononuclear cells (PBMCs) of patients with rheumatoid arthritis (RA) and its effect on inflammatory response and migration of synovial fibroblasts in RA (RA-FLS). METHODS: PBMCs were collected from 30 healthy individuals and 50 RA patients for detecting the expression of miR-342-3p, and its correlation with the clinical indicators RF, ESR, anti-CCP, hs-CRP, C3, DAS-28, SAS, and SDS was analyzed. In RA-FLS cultures, the effect of transfection of miR-342-3p mimics and inhibitor on TNF-α-induced inflammatory response of the cells was evaluated by detecting the expressions of IL-1β, IL-6, IL-10, and TNF-α using ELISA. CCK8 assay and Transwell assay were used for detecting the changes in cell viability and migration ability of the synovial cells. RESULTS: In RA patients, the expression level of miR-342-3p was significantly lowered in the PBMCs (P < 0.05) with an area under the ROC curve of 97.53% and showed inverse correlations with RF (r=-0.321), ESR(r=-0.284), anti-CCP (r=-0.355), hs-CRP (r=-0.320), C3 (r=-0.294), DAS-28 (r=-0.395), SAS (r=-0.366), and SDS (r=-0.397) (all P < 0.05); a low expression of miR-342-3p was strongly associated with elevated levels of anti-CCP, DAS-28, SDS, and SAS (all with a rule support greater than 85%, confidence greater than 88%, and lift greater than 1). In cultured RA-FLS, TNF-α stimulation significantly increased the cell viability (P < 0.05), upregulated the expressions of IL-1β, IL-6, and TNF-α, and lowered the expression of IL-10 (P < 0.05). These changes were significantly suppressed by transfection of the cells with miR-342-3p mimics (P < 0.05) but enhanced by transfection with miR-342-3p inhibitor (P < 0.05). CONCLUSION The expression of miR-342-3p is decreased in the PBMCs of RA patients. A lowered expression of miR-342-3p contributes to the pathogenesis of RA by promoting inflammatory responses and migration of RA-FLS.

Objective:To analyze the epidemiological and clinical characteristics of imported COVID-19 cases after SARS-CoV-2 vaccination and to provide evidence for the prevention and control of COVID-19.Methods:The imported COVID-19 cases in Chengdu as of April 15, 2021 were divided into the vaccinated group and unvaccinated group according to the history of SARS-CoV-2 vaccination. The epidemiological and clinical data of the cases were collected retrospectively, and the differences in epidemiological and clinical characteristics of the two groups were compared. Laboratory tests consisted of nucleic acid test, clinical index test, serum antibody test and lymphocyte test. Software WPS2019 was used for data management and software R 4.0.3 was used for statistical analysis.Results:A total of 75 COVID-19 cases were included in the analysis, in which 20 had received SARS-CoV-2 vaccination and only 4 with clinical symptoms, 55 patients did not receive SARS-CoV-2 vaccination, and 16 had clinical symptoms. In vaccinated group, the first injection time of vaccination ranged from July to November 2020, and 10 cases received two doses of vaccine simultaneously and 10 cases received two doses of vaccine at intervals of 14-57 days. The intervals between the completion of vaccination and the onset ranged from 87 days to 224 days. The differences in classification and clinical type between the two groups were significant. Significant differences were observed in case classification and clinical type between vaccinated group and unvaccinated group ( P<0.05). The vaccinated group had a relatively high proportion of asymptomatic infections (40.00%, 8/20), while mild infections were mainly observed in the unvaccinated group(76.36%,42/55). The differences in Ct values (ORF1ab gene and N gene) at the diagnosis were not significant between vaccinated group and unvaccinated group ( P>0.05), similar results were also observed in lymphocyte subtypes, procalcitonin and C-reactive protein level comparisons. Serum amyloid A level was higher in unvaccinated group than in vaccinated group ( P<0.05). However, the SARS-CoV-2 related serum antibody of IgM, IgG and total antibody levels were significantly higher in vaccinated group ( P<0.05). Conclusions:Risk of infection still exists with SARS-CoV-2 after vaccination, which can facilitate the production of specific serum antibody of IgM and IgG when people are exposed to the virus. It has a certain protective effect on SARS-CoV-2 infected persons. Vaccination can reduce the clinical symptoms and mitigate disease severity.
