前房注射卡波姆建立大鼠高眼压模型的观察

目的　前房注射卡波姆建立大鼠高眼压模型，观察卡波姆升眼压效果及对大鼠眼前节和视网膜的影响。方法　随机选取30只SD大鼠，注射前3 d早晚测量基线眼压。右眼定为实验眼，左眼定为对照眼，右眼放出房水后将30 μL的5 g·L^-1卡波姆混悬液注入前房，每日早10时、晚22时在大鼠清醒状态下测量眼压。每周进行双眼眼前节照相并对比。4周末处死26只大鼠（另4只持续观察眼压变化至注射后9周）并取双眼眼球行HE染色，观察实验眼与对照眼视网膜形态，对比视网膜厚度及房角形态。结果　注射前，实验眼白天和夜间眼压分别为（11.10±0.90）mmHg（1 kPa=7.5 mmHg）和（11.92±1.07）mmHg，对照眼分别为（11.22±1.07）mmHg和（11.76±1.08）mmHg；实验眼与对照眼相比，白天、夜间眼压差异均无统计学意义（均为 P＞0.05）；白天与夜间眼压相比，实验眼、对照眼差异均有统计学意义（均为P<0.05）。卡波姆在前房中呈现出弥散型和沉积型两种存在方式，弥散型和沉积型大鼠1周内眼压分别为（17.83±3.54）mmHg和（13.00±1.55）mmHg，两者相比差异具有统计学意义（P＜0.05）。注射后第1天至第19天，实验眼与对照眼白天眼压相比差异均具有统计学意义（均为P＜0.05）；注射后第1天至第27天，实验眼与对照眼夜间眼压相比差异均具有统计学意义（均为P＜0.05）。实验眼视网膜形态发生改变，注射后4周视网膜厚度为（254.70±21.80）μm，与对照眼的（346.73±24.63）μm相比，差异有统计学意义（P=0.00）。实验眼前房充满卡波姆及虹膜的混合成分，紧贴角膜内皮并延伸至房角，堵塞小梁网结构，正常虹膜形态消失；对照眼房角形态正常。结论　前房注射卡波姆建立大鼠高眼压模型，可维持高眼压4周以上，昼夜眼压差异较为明显，夜间眼压较白天更高，4周后视网膜出现高眼压损伤后的表现。     

中医药治疗慢性前列腺炎研究概况

综述近年中医药治疗慢性前列腺炎的临床研究,认为本病病因病机之核心在于脾肾亏虚为本,湿热、痰浊、瘀毒为标,病久则伤及脾肾,由实转虚。中医内治法主要以辨证论治、辨病论治或单方验方为主,外治法以中药洗浴、中药灌肠、肛门给药、针灸为主。中医药治疗本病优势明显。应继续完善对中医药作用机制的认识,制订统一的辨证论治及疗效评价标准,针对效果显著的名方开展研究。     

Two new bisamides from the leaves of Aglaia perviridis

Two new bisamides, aglaiamides A (1) and B (2), along with three known ones (3–5), were isolated from the leaves of Aglaia perviridis. Their structures were established on the basis of detailed spectroscopic analyses.     

Clinical analysis of peritoneal dialysis in the treatment of rapidly progressive glomerulonephritis

Objective To observe the clinical characteristics and prognosis of patients with rapidly progressive glomerulonephritis (RPGN) caused by lupus nephritis, antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis, or primary glomerulonephritis who were treated with peritoneal dialysis (PD) and then withdrew PD because of renal recovery. Methods Data of the above patients were retrospectively analyzed. The patients were diagnosed as RPGN and received PD therapy in Kidney Disease Center, the First Affiliated Hospital, College of Medicine, Zhejiang University from February 2009 to August 2018. The patients were divided into early withdrawal group (PD time≤183 days, n=24) and late withdrawal group (PD time＞183 day, n=24). The differences of clinical characteristics between the two groups were compared. The cumulative incidence of adverse events in both groups was analyzed using Kaplan-Meier curves. Cox proportional hazards model was used to analyze the risk factors influencing the prognosis of patients. Results Forty-eight RPGN patients were included. The median time of maintaining PD was 178(76, 378) days. Compared with the late withdrawal group, the patients in early withdrawal group had lower levels of urine volume, serum albumin and parathyroid hormone, and lower rates of gross hematuria and hypertension at the beginning of PD, and received higher rates of methylprednisolone impulse, combined immunosuppressive agents, and hemodialysis or continuous renal replacement therapy (all P＜0.05). At the time of PD withdrawal, the levels of serum creatinine, serum calcium, serum albumin and parathyroid hormone in the early withdrawal group were significantly lower than those in the late withdrawal group (all P＜0.05). The Kaplan-Meier curves showed that there was no significant difference in the cumulative survival of patients in both groups (log-rank test χ2=3.485, P=0.062). Cox regression analysis revealed serum creatinine≥209 μmol/L at the time of PD withdrawal was an independent risk factor for poor prognosis (HR=5.253，95%CI 1.757-15.702, P=0.003). Conclusions PD can be used for RPGN patients caused by lupus nephritis, ANCA-associated vasculitis and primary nephritis. Serum creatinine≥209 μmol/L at the time of PD withdrawal is an independent risk factor for poor prognosis.     

浙江省2007－2017年罕见病住院病例特征分析

目的 分析2007-2017年浙江省24 388例罕见病住院病例特征，为制定罕见病防控策略提供依据。方法 收集2007-2017年浙江省10家三级甲等（三甲）医院罕见病住院病例资料和各年度住院数，进行描述性统计分析。结果 罕见病病例共24 388例，占住院总例数的2.69‰（24 388/9 054 201），病例数居前3位的疾病类型依次为"血液和造血器官疾病以及某些涉及免疫机能的异常"（占32.81%，8 001/24 388）、"先天性畸形、变形和染色体异常"（占24.87%，6 065/24 388）和"神经系统疾病"（占19.01%，4 635/24 388）；2007-2017年罕见病病例数呈逐年增长趋势，年均增幅19.69%，而罕见病例数占同期住院总例数比例仅在2016-2017年明显上升，各类型罕见病时间分布呈不同特征；罕见病的病例数男女性别比为1.35：1（13 990/10 398），男女性别比最高的3类疾病依次为"消化系统疾病"（4.45：1，1 180/265）、"损伤、中毒和外因的某些其他后果"（3.51：1，281/80）和"神经系统疾病"（2.26：1，3 213/1 422）；各年龄段罕见病类型、各类型罕见病年龄分布均呈不同特征；病例数居前10位的疾病占全部罕见病例数的53.55%（13 060/24 388），其中前3位疾病分别为成人粒细胞缺乏症（14.41%，3 515/24 388）、皮质基底核退化症（7.60%，1 854/24 388）和亨诺克-舍恩莱因紫癜（6.01%，1 466/24 388）。结论 本研究分析的浙江省2007-2017年24 388例罕见病住院病例的特征资料，是推动我国罕见病的研究、监测或登记数据库构建、制定防控策略的参考依据。
