Objective To investigate the effects of cornuside on intestinal injury in rats with septic shock,and clarify its possible mechanism.Methods SD rats were randomly divided into normal control group,model group,low-,medium-,and high-dose comecarpine glycosides groups,and TREM1 inhibitor(LR12)group.HE staining was used to observe the pathological injury of small intestinal mucosa.The levels of D-lactic acid(D-LA)and diamine oxidase(DAO)in serum and secretory immunoglobulin(sIg A)in small intestine were detected by ELISA.Intestinal mucosal permeability was detected by fluorescein isothiocyanate-dextran(FITC-D)tracer method.ELISA was used to detect the levels of interferon(IFN)-γ,tumor necrosis factor(TNF)-α,interleukin(IL)-1β,IL-10 and arginase(Arg)-1 in serum.The polarization of macrophages in small intestinal tissue was detected by flow cytometry.Western blot was used to detect the protein expression levels of triggering receptor expressed on myeloid cells 1(TREM1),CD86 and CD206 in small intestine.Results Compared with the normal control group,the model group had serious pathological injury of the small intestinal mucosa,and the serum levels of D-LA,DAO,FITC-D,IFN-γ,TNF-α,and IL-1β significantly increased(P<0.05),while the levels of sIg A,IL-10,and Arg-1 significantly decreased(P<0.05).The M1/M2 ratio of macrophages and the expression levels of TREM1 and CD86 proteins in the small intestine tissue significantly increased(P<0.05),while the expression level of CD206 protein significantly decreased(P<0.05).Compared with the model group,the small intestinal mucosal injury of the rats in each dose cornuside group and LR12 group significantly improved,and the serum levels of D-LA,DAO,FITC-D,IFN-γ,TNF-α,and IL-1β significantly decreased(P<0.05),while the levels of sIg A,IL-10,and Arg-1 significantly increased(P<0.05).The M1/M2 ratio of macrophages and the expression levels of TREM1 and CD86 proteins in the small intestine tissue significantly decreased(P<0.05),while the expression level of CD206 protein significantly increased(P<0.05).Conclusion Cornuside can reduce intestinal injury in rats with septic shock,and the mechanism may be related to inhibiting TREM1-mediated M1 polarization of macrophages.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To assess the technical levels of computed tomography (CT) quality control testing capabilities among radiological health technology service institutions in Hubei Province, China. Methods Ten radiological health technology service institutions in Hubei Province were organized to participate in an inter-institutional capability comparison of selected indicators in CT quality control testing with reference to the Specification for testing of quality control in X-ray computed tomography (WS 519—2019). The robust Z-score method was employed to evaluate the results of the capability comparison data from the ten institutions. Results Six institutions achieved a "satisfactory" rating in all assessed indicators, with a satisfaction rate of 60%. Indicators rated as "unsatisfactory" or "questionable" included "positioning light accuracy", "uniformity", "noise", and "high-contrast resolution". Conclusion The CT quality control testing capabilities of some radiological health technology service institutions in Hubei Province require further enhancement. Improved training and education for testing personnel are recommended.

Objective:To systematically evaluate the clinical efficacy and safety of Tonifying kidney and activating blood thera-py for the treatment of diabetic mellitus erectile dysfunction.Methods:China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP,Chinese Biomedical Database(CBM),PubMed,Cochrane Library,Embase and Web of Science were searched from incep-tion until October 20th of 2024,for randomized controlled trials of Tonifying kidney and activating blood therapy for the treatment of dia-betic erectile dysfunction.Literature screening,quality evaluation,and data extraction were carried out in accordance with relevant standards.The software of RevMan5.4 was used for the analysis of publication bias.And meta-analysis was conducted to assess the im-pact of this therapy on IIEF-5,total effective rate,adverse reactions.The evidence levels according to the analysis results were evalua-ted.Results:Totally 19 RCTs were included,involving 1 612 patients.The result of meta-analysis indicated that Tonifying kidney and activating blood therapy had advantages on the improvement of IIEF-5 scores(MD=3.59,95％CI[2.14,5.03],P＜0.01),total effective rate(OR=4.30,95％CI[3.29,5.32],P＜0.000 01).However,there was no statistically significant difference in the inci-dence of adverse reactions(OR=0.98,95％CI[0.48,2.01],P=0.96)between the two groups.Conclusions:Tonifying kidney and activating blood therapy can improve the clinical efficacy and IIEF-5 score for the patients with diabetic erectile dysfunction.But considering the limited quantity of included studies,more high-quality studies still be needed to validate the therapeutic effect.

BACKGROUND: Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations. METHODS: In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively. RESULTS: 81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count. CONCLUSIONS In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.

Objective:To investigate the short-term efficacy and safety of Donafenib as postoperative adjuvant therapy for patients with high risk of recurrence after radical resection of hepatocellular carcinoma (HCC).Methods:The propensity score matching (PSM) and retrospective cohort study was conducted. The clinicopathological data of 157 HCC patients with high risk of recurrence after radical resection who were admitted to 6 medical centers, including The First Affiliated Hospital of Nanjing Medical University et al, from June 2021 to February 2023 were collected. There were 128 males and 29 females, aged (59±10)years. Of 157 patients, 101 cases undergoing Donafenib as postoperative adjuvant therapy were divided into the the Donafenib group, and 56 cases under-going no systemic postoperative adjuvant therapy were divided into the control group. Observation indicators: (1) PSM and comparison of general data of patients between the two groups after matching; (2) postoperative treatment; (3) follow-up and survival of patients; (4) analysis of risk factors affecting recurrence-free survival of patients. PSM was done based on the principle of optimal perfect matching, with the clamp value of 0.5, and the Donafenib group and the control group were matched at a ratio of 1.25∶1. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers and/or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Kruskal-Wallis H test. The Kaplan-Meier method was used to calculate survival rates and draw survival curves, and the Log-Rank test was used for survival analysis. The COX proportional hazard model was used for univariate and multivariate analyses. Results:(1) PSM and comparison of general data of patients between the two groups after matching. Of 157 patients, 126 cases were successfully matched, including 70 cases in the Donafenib group and 56 cases in the control group, respectively. The elimination of tumor number confounding bias ensured comparability between the two groups after PSM. (2) Postoperative treatment. After PSM, of 70 patients in the Donafenib group, there were 23 cases receiving Donafenib monotherapy, 26 cases combined with transcatheter arterial chemoembolization (TACE), 14 cases combined with immunotherapy, and 7 cases combined with TACE+immunotherapy. Of 56 patients in the control group, there were 37 cases receiving postoperative follow-up alone and 19 cases combined with TACE. (3) Follow-up and survival of patients. All 157 patients were followed up, and the follow-up time of the 101 patients in Donafenib group and the 56 patients in control group were 10.1(range, 6.3-14.6)months and 22.2(range, 15.1-25.5)months, respectively. During the follow-up period, 70 patients in the Donafenib group experienced treatment-related adverse reactions, inclu-ding 8 cases of grade 3 adverse reactions, 23 cases of grade 2 and 39 cases of grade 1 adverse reactions, respectively. After PSM, the postoperative 12-, 18-month recurrence-free survival rates were 83.7%, 83.7% in the 70 patients of Donafenib group and 67.8%, 58.9% in the 56 patients of control group, respectively, showing a significant difference in the postoperative recurrence-free survival time between the two groups ( hazard ratio=0.395, 95% confidence interval as 0.176-0.888, P<0.05). (4) Analysis of risk factors affecting recurrence free survival of patients. Results of multivariate ana-lysis showed that microvascular invasion, vascular thrombus, clinical stage as ⅢA were independent risk factors affecting recurrence-free survival in patients with high risk of recurrence after radical resection of HCC ( hazard ratio=2.181, 2.612, 2.612, 95% confidence interval as 1.028-4.629, 1.128-6.047, 1.128-6.047, P<0.05), Donafenib as postoperative adjuvant therapy was an independent protective factor affecting recurrence-free survival in patients with high risk of recurrence after radical resection of HCC ( hazard ratio=0.457, 95% confidence interval as 0.227-0.920, P<0.05). Results of further analysis showed that after PSM, there were significant differences in the postoperative recurrence-free survival time in patients with different clinical factors, including male, age ≥60 years, tumor diameter >5 cm, positive microvascular invasion, positive hepatitis B virus infection, alpha fetoprotein <200 μg/L, between the Donafenib group and the control group ( hazard ratio=0.283, 0.202, 0.174, 0.345, 0.273, 0.180, 95% confidence interval as 0.114-0.707, 0.044-0.937, 0.038-0.794, 0.128-0.929, 0.091-0.819, 0.052-0.620, P<0.05). Conclusion:Donafenib as postoperative adjuvant therapy can effectively reduce the short-term recurrence rate in patients with high risk of recurrence after radical resection of HCC, with good safety and tolerance.
