目的 探讨不同性别IgA肾病患者合并高尿酸血症的临床及肾脏病理特点。 方法 采用回顾性研究方法，将2008年1月－2010年12月收治的226例经肾活检确诊的原发性IgA肾病患者分为男性高尿酸血症组、男性尿酸正常组、女性高尿酸血症组及女性尿酸正常组4组，统计分析4组的临床指标及病理指标。 结果 高尿酸血症患病率男性（21.7%）高于女性（11.9%），差异有统计学意义（P＜0.01），尿检异常型患病率男性（14.6%）高于女性（4.0%），差异有统计学意义（P＜0.01），女性LeeⅢ级的患病率（7.1%）高于男性（5.8%），差异有统计学意义（P＜0.01）；男性高尿酸血症组的尿素氮高于尿酸正常组（P＜0.05），女性高尿酸血症组的血尿素氮、血肌酐、胱抑素C、舒张压、甘油三酯比尿酸正常者明显增高（P＜0.01），女性高尿酸血症组的高密度脂蛋白明显高于男性组（P ＜0.01）。 结论 高尿酸血症是IgA肾病的危险因素，可导致更严重的肾功能损害及肾脏病理损害，这种影响在不同性别中存在差异。
Objective To evaluate the effectiveness and safety of indocyanine green fluorescence method versus modified inflation-deflation method for thoracoscopic anatomic segmentectomy. Methods CNKI, Wanfang Database, China Biomedical Literature Database, Web of Science, Cochrane Library, EMbase, PubMed, Clinicaltrials.gov, were searched from 1 January 2000 to 1 May 2023, and controlled studies between indocyanine green fluorescence and modified inflation deflation method in thoracoscopic segmentectomy were collected. Meta-analysis was performed using Stata14MP and RevMan5.4. Results A total of 10 articles, including 1 156 patients, were identified. In thoracoscopic anatomic segmentectomy, indocyanine green fluorescence method had an advantage over modified inflation deflation method. The total incidence of postoperative complications decreased (OR=0.51, 95%CI 0.36 to 0.71, P<0.0001). The incidence of air leaks decreased (OR=0.50, 95%CI 0.31 to 0.80, P=0.004), the operation time shortened (MD=−25.81, 95%CI −29.78 to −21.84, P<0.00001), the length of postoperative hospital stays shortened (MD=−0.98, 95%CI −1.57 to −0.39, P=0.001), the rate of clear displaying for intersegmental boundary line increased (OR=5.79, 95%CI 2.76 to 12.15, P<0.00001). The difference was statistically significant. Conclusion Compared with modified inflation deflation method, indocyanine green fluorescence method can quickly and clearly display the intersegmental boundary line, reduce the difficulty of surgery, shorten the operation time, reduce the length of postoperative hospital stay, and provide reliably technical support for thoracoscopic anatomic segmentectomy. It is an effective and safe method, which is worthy of extensive application.
Objective To assess the efficacy and safety of okra capsule for IgA nephropathy. Methods All randomized or quasi-randomized controlled trials (RCTs or quasi-RCTs) of okra capsule for IgA nephropathy were collected from CENTRAL, MEDLINE, EMbase, PubMed, WanFang Data, CNKI and CBM. Two reviewers independently screened the included studies, extracted the data, assessed the quality, and cross-checked then. Then RevMan 5.07 software was used for meta-analysis. Results Five RCTs were included. The results of meta-analyses showed that: compared with the control group, okra capsule was more effective in decreasing urinary protein (P≥0.05), but had no significant difference in improving renal function, reducing urine red blood cells and blood lipid (Plt;0.05). No research reported the adverse effects of okra capsule. Conclusion Current evidence reveals that okra capsule can reduce urinary protein and improving therapeutic effect for IgA nephropathy. However, further studies are needed to test its safety. Because of the small sample size and low methodological quality of the included studies, these results require more high-quality RCTs for further verification.
Objects The center of Evidence Based Medicine (EBM) in China has organized several extra-curricular trainings in summer vacations for medical students, so as to enable them get involved in the practice of Evidence Based Medicine, we were wondering whether these training courses served as an effective supplement to EBM education in class and what it exactly brought to us, with a primary concern about research capability in field of EBM. Methods We conducted questionnaire survey with undergraduate students whose enrolling years range from 2001 to 2005 in West China Medical School of Sichuan University, and divided them into a stratification of five groups according to enrolling years. Then we paired the trained students with untrained ones at a ratio of 1׃2. The final number of included students was 216, of which 72 had been trained while other 144 had not. Epidata 3.0, Excel and SPSS 13.0 were used for data collecting and analyzing, respectively. Chi-square test was adopted for result interpretation. Results Compared to those without training experience, trained students were prone to choose medical specialized databases (Plt;0.05) when they search for some academic publications. In terms of selecting and quality evaluation, the trained were more dependent on systematic reviews (Plt;0.05). Meanwhile, they also showed critical thinking more than that of untrained (Plt;0.05). In addition, the fruit of published theses was in favor of those trained ones. Conclusions Those who have taken part in extra-curricular training of EBM surpass those untrained in ability of scientific research. To some extent, we are still in shortage of educational resources; this extra-curricular training course can play a complementary role for EBM education, as effective and necessary.
