AIM: To investigate and analyze serum nitric oxide synthase 4(NOX4)and matrix metalloproteinase(MMP)-2 expressions in patients with diabetes mellitus(DM)complicated with neovascular glaucoma(NVG)and their clinical significance.METHODS: A prospective study was conducted on 161 patients with DM complicated with NVG admitted to Handan City Eye Hospital(The Third Hospital of Handan)from June 2020 to June 2023. Based on whether complications occurred 1 a after trabeculectomy in the study group patients, they were divided into a group with good prognosis(n=90)and a group with poor prognosis(n=71). During the same period, 161 patients with chronic angle-closure glaucoma without iris neovascularization were selected as the control group. ELISA method was applied to detect the expression levels of serum NOX4 and MMP-2. ROC curve was plotted to evaluate the diagnostic value and postoperative complication prediction value of NOX4 and MMP-2 in patients with DM complicated with NVG. Pearson method was applied to analyze the correlation of NOX4 and MMP-2 with vascular endothelial growth factor(VEGF)and interleukin-6(IL-6). Multivariate Logistic regression was applied to analyze the influencing factors of postoperative complications in the study group.RESULTS:The general information of the study group and control group of patients is comparable. Compared with the control group, the expression levels of serum NOX4, MMP-2, VEGF, and IL-6 in the study group were significantly increased(P<0.001). According to Pearson analysis, serum NOX4 and MMP-2 levels significantly positively correlated with VEGF and IL-6 levels, respectively(P<0.001). According to ROC curve, the AUC of NOX4 combined with MMP-2 in the diagnosis of DM complicated with NVG was better than that of individual diagnosis of NOX4(Z=3.341, P<0.05)and MMP-2(Z=2.788, P<0.05). The duration of DM, the proportion of people with intraocular pressure >21 mmHg, and the expression levels of NOX4, MMP-2, VEGF, and IL-6 in the poor prognosis group were all higher than those in the good prognosis group(P<0.001). The duration of DM, intraocular pressure >21 mmHg, the levels of NOX4, MMP-2, VEGF, and IL-6 were all risk factors for poor prognosis in DM patients with NVG(P<0.001). According to ROC curve, the combined prediction of NOX4 and MMP-2 for postoperative complications in patients with DM complicated by NVG was superior to the AUC predicted by NOX4(Z=3.727, P<0.05)and MMP-2(Z=2.219, P<0.05), respectively.CONCLUSION:NOX4 and MMP-2 are upregulated in the serum of patients with DM complicated by NVG. Combined detection of these two markers holds significant clinical value for the early diagnosis and prognosis of patients with DM complicated by NVG.

AIM:To analyze the influencing factors of postoperative malignant glaucoma(MG)in patients with primary angle-closure glaucoma(PACG)using logistic regression and decision tree models.METHODS:A retrospective study was conducted on PACG patients who underwent surgery at Eye Hospital of Handan City from March 2020 to March 2025. Patients were divided into two groups: the MG group, who developed MG within 6 mo postoperatively, and the non-MG group. Data were collected from the electronic medical record system. Univariate analysis was performed, followed by multivariate logistic regression to identify independent risk factors. A classification and regression tree model was constructed to visualize the hierarchical relationships among predictors. The predictive performance of the two models was evaluated and compared using receiver operating characteristic(ROC)curve analysis.RESULTS:Totally 182 cases(182 eyes)with PACG were enrolled in this study, including 91 cases(91 eyes)in the MG group and 91 cases(91 eyes)in the non-MG group. In the MG group, there were 53 males and 38 females; 69 cases were aged ≥60 y and 22 cases were aged <60 y. In the non-MG group, there were 47 males and 44 females; 33 cases were aged ≥60 y and 58 cases were aged <60 y. The non-MG group comprised 91 patients, including 47 males and 44 females. Among them, 33 cases were aged ≥60 y, and 58 cases were aged<60 y. The MG group had significantly higher proportions of patients aged ≥60 y, diabetes, moderate-stage PACG, persistent high intraocular pressure(IOP), complete anterior chamber angle closure, lens thickness <4.5 mm, axial length <22 mm, and severe postoperative inflammation compared to the non-MG group(all P<0.01). Multivariate Logistic regression identified the following as independent influencing factors for postoperative MG: age [OR (95%CI)=2.136(1.401-3.255)], PACG stage [OR (95%CI)=2.996(2.044-4.391)], IOP [OR (95%CI)=3.527(1.604-7.755)],anterior chamber angle [OR (95%CI)=4.826(2.498-9.324)], axial length [OR (95%CI)=5.125(1.265-20.771)], and severe postoperative inflammation [OR (95%CI)=2.338(1.478-3.699)](all P<0.05). The decision tree model selected six explanatory variables: age, PACG stage, IOP, anterior chamber angle status, axial length, and severe postoperative inflammation. Axial length was the primary splitting factor at the root node. The areas under the ROC curve(AUC)for the logistic regression and decision tree models were 0.913(0.863-0.950)and 0.921(0.872-0.956), respectively, with no significant difference between them(Z=0.561, P=0.575).CONCLUSION:Both the logistic regression and decision tree models effectively identify key influencing factors for postoperative MG in PACG patients, including age, PACG stage, IOP, anterior chamber angle status, axial length, and severe postoperative inflammation. The decision tree model offers an intuitive, visual representation of risk stratification, facilitating clinical decision-making. Both models are applicable for clinical risk assessment.

Objective: To comprehensively evaluate the clinical efficacy of a single dose of tranexamic acid (TXA) in reducing perioperative blood loss in patients undergoing craniomaxillofacial plastic and cosmetic surgery through meta-regression analysis. Methods: Embase, PubMed, Wanfang Data, VIP database, China National Knowledge Infrastructure (CNKI), the Chinese Clinical Trial Registry (ChiCTR) and Cochrane Central Register of Controlled Trials (CENTRAL) were electronically retrieved to collect clinical studies evaluating efficacy of perioperative TXA administration in patients undergoing craniomaxillofacial plastic and cosmetic surgery, from inception to August 2024. Quality assessment of randomized controlled trials (RCTs) was performed using Cochrane Collaboration's Risk of Bias Tool. Based on the results of methodological heterogeneity, corresponding meta-analyses were conducted using either random-effects or fixed-effects models in R programming software. Results: Thirty-one articles were included, involving 2 072 patients who underwent craniomaxillofacial plastic and cosmetic surgeries. Among these patients, 1 051 were in the TXA treatment group, and 1 021 were in the control group. The paired meta-analysis showed that compared with the control group, the use of TXA significantly reduced bleeding volume in perioperative patients [standardized mean difference (SMD)=-1.13; 95%CI (-1.47, -0.80), P<0.001]. Subgroup analysis revealed that TXA significantly reduced intraoperative bleeding volume in patients across different surgeries, with the order of efficacy as follows: orthognathic surgery [SMD=-1.44; 95%CI (-2.07, -0.80), P<0.001], cleft palate repair [SMD=-1.32; 95%CI (-2.14, -0.50), P<0.001], rhinoplasty [SMD=-0.97; 95%CI (-1.63, -0.30), P<0.001], and craniosynostosis [SMD=-0.96; 95%CI (-1.40, -0.53), P=0.040]. The result of the meta regression showed there was no significant difference in the hemostatic effect of TXA on patients with increasing doses (5, 10, 15, 20, 25 mg/kg) (P=0.650). Sensitivity analysis verified that the pooled values were stable and reliable. The Egger's test indicated a certain degree of publication bias (Z=-3.40, P<0.001). Conclusion: Existing evidence suggests that TXA effectively reduces perioperative blood loss in patients undergoing craniofacial plastic surgery, regardless of its dosage administered.

Objective:To examine the perioperative safety of laparoscopic cholecystectomy in human immunodeficiency virus (HIV)-positive patients undergoing antiretroviral therapy.Methods:A retrospective cohort study method was employed to collect clinical data from 388 patients with gallstones who were admitted to Department of General Surgery of the Provincial Hospital of Anhui Medical University between January 2020 and December 2023. The cohort comprised 135 males and 253 females. For the purpose of analysis, the participants were divided into HIV-positive group ( n=25) and HIV-negative group ( n=363). The distinction between the two groups was based on whether the participants were co-infected with HIV. The clinical and pathological data pertaining to the two groups of patients, along with the intraoperative and postoperative data, were collated. The propensity score matching method was employed to control for confounding bias, and the data on anaesthesia methods, intraoperative blood loss, duration of surgery, necessity for conversion to laparotomy, postoperative complications, postoperative drainage volume, postoperative hospital stay, and total treatment costs were compared between the two groups. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s) and compared using the t-test. Measurement data with skewed distribution were expressed as M( Q1, Q3) and compared using the rank-sum test. The Fisher exact probability method or the chi-square test was employed for the comparison of count data. Results:The two groups of general data were found to be statistically significant in terms of gender, preoperative red blood cells, neutrophils, alanine aminotransferase, and indirect bilirubin exhibited statistically significant differences( P<0.05). Following propensity score matching, a total of 59 cases were identified. Of these, 25 cases were observed in the HIV-positive group, while 34 cases were observed in the HIV-negative group. No statistically significant differences were observed between the two groups with respect to the general data ( P>0.05). No statistically significant difference was observed between the two groups in terms of anaesthesia method, intraoperative blood loss, duration of surgery, need for conversion to laparotomy, postoperative complication rate, postoperative drainage volume and postoperative hospital stay ( P>0.05). The total length of hospital stay and total hospital expenses in the HIV-positive group were 5.0 (3.0, 7.0) days and (14 829.3±4 852.8) yuan, respectively. HIV-negative group were 3.0 (2.0, 4.8) days and (10 762.3±1 850.3) yuan, respectively. The HIV-negative group had a significantly shorter hospital stay and lower hospital expenses, these differences were statistically significant ( P<0.05). There was no occupational exposure of medical personnel in the perioperative period among those with HIV. Conclusions:Laparoscopic cholecystectomy is a safe and feasible procedure for HIV-positive patients who are receiving antiretroviral therapy. Adherence to established protocols by healthcare personnel can mitigate the risk of occupational exposure.

Type 1 diabetes is characterized by an absolute deficiency of insulin. Exogenous insulin replacement therapy is a crucial treatment approach for type 1 diabetes. However, the non-physiological insulin administration can lead to iatrogenic hyperinsulinemia, exacerbate peripheral insulin resistance, and subsequently increase the risk of various complications. Emerging insulin infusion technologies, lifestyle interventions, and medications such as metformin are increasingly being utilized in type 1 diabetes management to lower plasma insulin levels and improve patient outcomes.

Objective To analyze the current situation and influencing factors of health-care seeking delay among pulmonary tuberculosis patients in Qingpu District of Shanghai from 2011 to 2022, and to provide a scientific basis for tuberculosis prevention and control. Methods The data of pulmonary tuberculosis patients in Qingpu District of Shanghai from 2011 to 2022 was collected through the China Tuberculosis Information Management System to describe the distribution and change trend of the delay in health-care seeking. Univariate analysiswas performed using the chi-square (χ²) test, and the time trend of rates was tested with the trend chi-square (trend χ²) test. Multivariate logistic regression model analyzed the influencing factors of the delay in health-care seeking. Results From 2011 to 2022, there were 3 488 cases of pulmonary tuberculosis in Qingpu District, with 1 438 patients experiencing health-care seeking delay. The median (quartile) number of days of delay was M (P25, P75) = 10 (2, 24) days, and the rate of health-care seeking delay was 41.23%. The annual rate of health-care seeking delay fluctuated between 33.88% and 50.45% from 2011 to 2022, with statistically significant differences between different years (χ²=38.355, P<0.001), and an upward trend in the health-care seeking delay rate was observed from 2020 to 2022 (χtrend²=13.290, P<0.001). Multivariate logistic regression analysis showed that compared to male, those under 25 years old, with local household registration, and detected through health check-ups, females (OR=1.21, 95%CI:1.04-1.41), those aged 45 to <65 (OR=1.36, 95%CI:1.06-1.75), intra-city migrants (OR=1.35, 95%CI:1.09-1.68), inter-provincial/overseas migrants (OR=1.50, 95%CI:1.23-1.83), and patients who directly sought medical care (OR=3.52, 95%CI:2.27-5.47), transfer treatment (OR=2.07,95%CI:1.31-3.25), referral (OR=2.16, 95%CI:1.36-3.44), follow-up (OR=3.07, 95%CI:1.74-5.44) patients with pulmonary tuberculosis were more likely to delay health-care, and the differences were statistically significant (P<0.05). Compared to sputum-positive patients, those with sputum-negative tests (OR=0.76, 95%CI: 0.59-0.97) were less likely to experience delayed health-care, and the difference was statistically significant (P<0.05). Conclusions Health-care seeking delay of pulmonary tuberculosis patients is relatively common in Qingpu District of Shanghai. Corresponding intervention measures should be adopted for risk factors and key populations to further improve the health-care seeking delay.

Wound infection is becoming a considerable healthcare crisis due to the abuse of antibiotics and the substantial production of multidrug-resistant bacteria. Seawater immersion wounds usually become a mortal trouble because of the infection of Vibrio vulnificus. Bdellovibrio bacteriovorus, one kind of natural predatory bacteria, is recognized as a promising biological therapy against intractable bacteria. Here, we prepared a B. bacteriovorus-loaded polyvinyl alcohol/alginate hydrogel for the topical treatment of the seawater immersion wounds infected by V. vulnificus. The B. bacteriovorus-loaded hydrogel (BG) owned highly microporous structures with the mean pore size of 90 μm, improving the rapid release of B. bacteriovorus from BG when contacting the aqueous surroundings. BG showed high biosafety with no L929 cell toxicity or hemolysis. More importantly, BG exhibited excellent in vitro anti-V. vulnificus effect. The highly effective infected wound treatment effect of BG was evaluated on mouse models, revealing significant reduction of local V. vulnificus, accelerated wound contraction, and alleviated inflammation. Besides the high bacterial inhibition of BG, BG remarkably reduced inflammatory response, promoted collagen deposition, neovascularization and re-epithelization, contributing to wound healing. BG is a promising topical biological formulation against infected wounds.
