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.

Objective:To comprehensively evaluate the clinical effectiveness with respect to a single dose of tranexamic acid (TXA) given preoperatively for blood loss control in perioperative patients accepted craniomaxillofacial plastic and cosmetic surgery.Methods:Embase, PubMed, WanFang Data, VIP, China National Knowledge Infrastructure (CNKI), the Chinese Clinical Trial Registry (ChiCTR) and Cochrane Central Register of Controlled Trials (CENTRAL) were electronically retrieved to collect randomized controlled trials (RCTs) related to appraise the efficacy in perioperative craniomaxillofacial plastic and cosmetic surgery patients used TXA from inception to August 2024. Based on the result of methodological heterogeneity, corresponding paired meta-analyses were carried out with a random-effects or fixed-effects model applying R 4.0.4 software. Subgroup analysis was performed based on type of surgery, patient age, regional distribution of patients, and sample size included in the studies. A meta-regression analysis was performed on studies that reported the effect of different doses of TXA on reducing perioperative bleeding. Sensitivity analysis was performed to verify the stability of the meta result. Egger’s test was used to analyze potential publication bias.Results:A total of 31 RCTs were included, involving 2 072 patients, with 1 051 in the TXA group and 1 021 in the placebo group. The paired meta-analysis random-effects model ( I2=90%) showed that compared with the control group, the use of TXA significantly reduced the amount of bleeding in perioperative patients[standardized mean difference ( SMD)=-1.13, 95% CI -1.47 to -0.80, P < 0.01]. Subgroup analysis revealed that TXA had a significant effect on reducing intraoperative bleeding in patients with different surgeries, ages, regions, and sample sizes. The most effective subgroups were cases in orthognathic surgery ( SMD=-1.44, 95% CI -2.07 to -0.80, P< 0.01), less than 30 year-old( SMD=-1.32, 95% CI -1.68 to -0.96, P< 0.01], Asian patients( SMD=-1.29, 95% CI -1.72 to -0.86, P< 0.01), less than 30 individuals ( SMD=-1.16, 95% CI -1.50 to -0.82, P< 0.01). 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>0.05). Sensitivity analysis verified that the pooled values were stable and reliable. The Egger’s test indicated a certain degree of publication bias ( P < 0.01). Conclusion:Taken as a whole, existing evidence suggests that TXA can effectively reduce perioperative bleeding in patients undergoing craniofacial plastic surgery, regardless of its dosage administered. However, further clinical researches are still needed to provide more baselined data, transfusion-related indicators, and information on adverse events such as vascular embolism, in order to comprehensively evaluate and analyze the efficacy and safety of a single dose of TXA for perioperative blood loss control in patients treated with craniomaxillofacial plastic and cosmetic surgery.

The reliability and practicality of research findings in health economics are gradually becoming core issues of close concern for clinical and public health experts. As healthcare resources remain under increasing pressure, conducting efficient cost-effectiveness analyses and achieving rational resource allocation are becoming ever more critical. In recent years, medical laboratory health economics has transitioned from purely academic discussions to integration into clinical practice, becoming a key tool for improving the efficiency and quality of healthcare services. It has demonstrated remarkable results in optimizing patient management and medical decision-making processes. So we invited experts from the fields of medical laboratory science and health economics to share valuable experiences and unique insights on topics such as cost assessment methods, pricing strategies, quality regulation, and the role of medical laboratory health economics in enhancing clinical practice and patient benefits. These experts generally agree that, while research in medical laboratory health economics has shown significant advantages and effectively addressed urgent clinical needs in resource allocation and cost control, it still faces multiple challenges, including limitations in research methodology application, high operational costs, and insufficient standardization of management systems.

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.

An overview of the application of association rule mining(ARM)in real-world study(RWD)on drug safety to inform pharmacovigilance real-world data analysis.The applications of ARM in RWD of drug safety were divided into single drug/vaccine signal detection,combined medication risk mining,multidimensional risk factor analysis and adverse drug event occurrence characterization based on passive monitoring data;medication characterization pattern analysis,auxiliary epidemiological study design and risk mining of the whole dataset based on active monitoring data.In general,foreign scholars pay more attention to method rule setting,performance evaluation and application research,while domestic scholars pay more attention to multidimensional risk factor analysis,adverse drug event occurrence pattern,and clinical drug use characteristics research.With the accumulation of medical data and the continuous development of data mining technology,ARM may provide new ideas for RWD on drug safety.

Objective:To focus on clinical mini-lectures characterized by flexible teaching formats and significant challenges in scoring during supervision, systematically explore the roles and characteristics of raw scores (directly assigned by supervisory experts) and standard scores (revealing the relative position of instructors withing the group through Z-score conversion) in evaluating the teaching level and development trends of residency training teachers, investigate the feasibility of flexibly combining these two scoring methods, and provide new ideas for comprehensive, scientific, and objective teaching evaluations. Methods:In May 2024, 24 teachers who were supervised by three or more experts at a standardized training base for residents from 2019 to 2023 were selected as the research subjects. The study analyzed differences in mean rankings and development trends between raw and standard scores. Excel and SPSS were used for score transformation and statistical analysis of differences.Results:The mean rankings of standard scores differed from those of raw scores for 17 (70.83%) teaching staff members, among which 8 (33.33%) had a lower mean ranking of standard scores than raw scores, and 9 (37.50%) had an improved mean ranking of standard scores. For 10 (41.67%) teaching staff members, the differences in raw scores given among different supervisors were reversed after standardization conversion. The changes in the trends of scores for 17 (70.83%) teaching staff members throughout the years were inconsistent before and after score conversion.Conclusions:There were significant differences between the statistical results of standard scores and raw scores, and the two types of results evaluated the teaching level of teachers in terms of absolute situation and their relative positions in the entire teaching staff group, respectively. Therefore, combining the two types of scores with distinct characteristics for teaching evaluation can help teaching management departments comprehensively and objectively reveal the teaching level of teachers, while enhancing the confidence of faculty in teaching.

Objective:To review the application of internet cognitive behavioral therapy (CBT) in perinatal women with negative emotions, point out the limitations of existing studies, and put forward development suggestions for future research.Methods:Using the Scope review guide published by Joanna Briggs Institute as the methodological framework, eight Chinese and English databases including China National Knowledge Infrastructure (CNKI), Wanfang, PubMed and Web of Science were searched until July 1, 2024, and the literatures were collected and analyzed.Results:A total of 18 literatures were included. The interventionists of internet cognitive behavioral therapy were mostly psychologists; the intervention methods were mostly in the form of partial participation of therapists, and the intervention platforms were mostly websites. The intervention content was centered on mental health education, emotional monitoring, cognitive reconstruction, behavioral activation training, and problem solving. There were 15 studies that demonstrated that internet cognitive behavioral therapy was effective, and three studies showed that internet cognitive behavioral therapy was not effective in improving negative emotions in perinatal women, but perinatal women responded to treatment.Conclusions:The Internet cognitive behavioral therapy can effectively improve the negative emotions of perinatal pregnant women, but the long-term effect is not clear. Future studies can expand the sample size and follow up the effect for a long time.

Metastatic castration-resistant prostate cancer (mCRPC) is often resistant to conventional therapies, and prostate-specific membrane antigen (PSMA)-targeted radionuclide therapy has emerged as a promising therapeutic strategy. Ligands such as 177Lu-PSMA and 225Ac-PSMA have demonstrated clinical benefits in ongoing studies and show potential when combined with endocrine therapy, chemotherapy, immunotherapy, and radiotherapy. Additionally, novel therapeutic approaches, including PSMA-targeted antibody-drug conjugates (ADCs), chimeric antigen receptor T-cell (CAR-T) therapy, and bispecific T-cell engagers (BiTEs), are being actively explored. This review summarizes the recent advancements in PSMA-targeted treatment and their clinical applications.
