基于蒙医白脉理论探析帕金森病＊

帕金森病是以多巴胺能神经元减少导致的以静止性震颤、肌强直、运动迟缓和姿势步态障碍为主要临床症状的疾病。此病是蒙医白脉病的一种，又称彻彻热乎病。蒙医将人体的脉络分为白脉和黑脉。白脉病是白脉系统遭受致病因素的影响后所致的一系列疾病的总称，临床上很多疾病归属于“白脉病”。为更好的实现对蒙医优势单病种的规范化研究，本文基于白脉理论，探析蒙医对帕金森病的认识，以期为未来的研究提供理论支持。     

Method’s corner: Allergist’s guide to network meta-analysis

Network meta-analyses (NMAs) simultaneously estimate the effects of multiple possible treatment options for a given clinical presentation. For allergists to benefit optimally from NMAs, they must understand the process and be able to interpret the results. Through a worked example published in Pediatric Allergy and Immunology, we summarize how to identify credible NMAs and interpret them with a focus on recent innovations in the GRADE approach (Grading of Recommendations Assessment, Development, and Evaluation). NMAs build on traditional systematic reviews and meta-analyses that consider only direct paired comparisons by including indirect evidence, thus allowing the simultaneous assessment of the relative effect of all pairs of competing alternatives. Our framework informs clinicians of how to identify credible NMAs and address the certainty of the evidence. Trustworthy NMAs fill a critical gap in providing key inferences using direct and indirect evidence to inform clinical decision making when faced with more than two competing courses of treatment options. This document will help allergists to identify trustworthy NMAs to enhance patient care.     

基于糖脂代谢研究筋疽（糖尿病足非缺血性坏疽）湿热毒盛证

[目的]通过现代检验技术研究筋疽(糖尿病足非缺血性坏疽)湿热毒盛证的糖脂代谢指标。[方法]收集136例筋疽(糖尿病足非缺血性坏疽)患者进行不同证型间指标的比较。[结果]湿热毒盛证患者空腹血糖(FBG)、糖化血红蛋白(HbA1c)、餐后2 h血糖(2 hPBG)、晚期糖基化终末产物(AGEs)、白蛋白(ALB)、总胆固醇(TC)、高密度脂蛋白(HDL-C)与其他证型比较存在统计学差异(P<0.05)。湿热毒盛证患者C-反应蛋白(CRP)、人可溶性血管细胞黏附分子1(sVCAM-1)与其他证型组间比较存在统计学差异(P<0.01)。[结论]筋疽(糖尿病足非缺血性坏疽)湿热毒盛证形成的原因与低营养状态下糖脂代谢紊乱引起的高血糖及持续炎症反应相关。     

BRCA1/2突变的中国健康女性乳腺预防性切除及Ⅰ期重建的临床实践

目的:探讨对携带BRCA1/2突变的中国健康女性实施乳腺预防性切除及I期重建的可行性。方法:选择2018年1月至2019年2月3例于北京大学国际医院就诊的携带BRCA1/2突变的中国健康女性,其中2例携带BRCA1突变、1例携带BRCA2突变,均有乳腺癌家族史,年龄为34~36岁,实施预防性保留乳头-乳晕的双侧乳腺切除和Ⅰ期假体重建术。结果:3例患者术后无并发症发生,术后中位随访时间为18个月,均无乳腺癌发生,对重建乳房外形满意,且焦虑和恐惧情绪显著下降,取得良好的疗效。结论:对携带BRCA1/2突变且有乳腺癌家族史的中国健康女性,在严格筛选的基础上,可慎重开展乳腺预防性切除及Ⅰ期重建术。     

The predictive value of crescents in adult Henoch-Sch?lein purpura nephritis

Objective To study the renal prognosis with the type and proportion of crescentic in adult Henoch Schonlein purpura nephritis (HSPN). Methods A total of 275 HSPN cases diagnosed in the First Affiliated Hospital of Zhejiang University were retrospectively analyzed. According to the pathological results, they were divided into four groups: 99 patients in none crescent group (NC), 35 patients in segmental crescents group (SC), 122 patients with circumferential crescent ＜25% (C1), and 19 patients with circumferential crescent≥25% (C2). Renal prognostic events were defined as estimated glomerular filtration rate (eGFR) decreased by 30% over baseline within 2 years, doubling of serum creatinine or end-stage renal disease during follow-up. Kaplan-Meier survival analysis was used to compare the renal survival rate of each group. Univariate and multivariate Cox regression model was used to recognize the risk factor of poor renal outcome. Results There was no significant difference in age, extra renal organ performance and mean arterial pressure among groups. Among NC group, SC group, C1 group and C2 group, difference in serum creatinine (P=0.001), eGFR (P=0.003) and proteinuria levels (P＜0.001) were statistically significant. There was no significant difference in the ratio of global sclerosis, mesangial hypercellularity and interstitial inflammation/fibrosis among the groups. The patients were followed up for 86(58, 116) months. The renal survival rates of NC group, SC group, C1 group and C2 group were 96%, 100%, 83.6% and 68.4% respectively. Kaplan-meier survival analysis showed significant differences (Log Rank=23.24, P＜0.001). Cox multivariate regression analysis indicated that presence of circumferential crescent (HR=3.59, 95%CI 1.34-9.62, P=0.008) and low eGFR (HR=0.979, 95%CI 0.968-0.989, P＜0.001) were independent prognostic factors. Conclusion The presence of circumferential crescent and low eGFR level are independent risk factors for poor renal prognosis in HSPN patients.
