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.     

黄连解毒汤对重度颅脑损伤合并肺部感染患者血气指标和炎症因子影响分析

目的:观察黄连解毒汤对重度颅脑损伤合并肺部感染患者血气指标和炎症因子的影响,探讨其治疗效果。方法:随机抽签方式将77例重度颅脑损伤合并肺部感染患者分为两组。对照组35例接受常规治疗,研究组42例在常规治疗基础上,联合黄连解毒汤直肠灌注及全身擦浴治疗。评估两组临床效果,记录两组呼吸机使用时间、ICU入住时间及治疗费用,测定两组治疗前后血气指标和炎症因子。结果:两组临床治疗效果间差异无统计学意义(P>0.05)。与对照组比,研究组呼吸机使用时间和ICU入住时间明显缩短,ICU治疗费用显著减少(P<0.01)。治疗后两组SaO、PaO₂水平明显上升,PaCO₂及血清PCT、IL-1β、HMGB-1、CRP水平明显下降(P<0.05)。组间比较,研究组SaO、PaO₂水平高于对照组,PaCO₂及血清PCT、IL-1β、HMGB-1、CRP水平低于对照组(P<0.05)。结论:黄连解毒汤直肠灌注联合全身擦浴可明显控制重度颅脑损伤合并肺部感染患者感染病症,改善血气指标,调节炎症反应,缩短呼吸机使用时间和ICU入住时间,减少患者的治疗费用。     

听神经瘤术后面神经功能损伤危险因素分析

目的分析影响听神经瘤患者术后短期及长期面神经功能的危险因素。 方法回顾性分析厦门大学附属第一医院神经外科自2015年1月至2018年6月收治的62例听神经瘤患者的临床资料。于术后7 d及术后6个月对所有患者的面神经功能进行评估。收集可能与患者术后早期及长期面神经功能障碍存在相关性的因素，采用Logistic单因素与多因素回归对相关因素与患者术后短期及长期面神经功能的关系进行分析。 结果术后7 d，21例（33.9%）患者面神经功能正常，41例（66.1%）患者出现面神经功能损伤；术后6个月，49例（79.0%）患者面神经功能为正常，13例（21.0%）患者面神经功能损伤。Logistic单因素回归分析结果显示：肿瘤最大直径越大、肿瘤与面神经黏连越紧密，患者术后7 d发生面神经功能损伤的可能性越大（P=0.002、0.002）；术前临床症状持续时间为患者术后6个月面神经功能障碍的危险因素（P=0.035）。Logistic多因素回归分析结果显示：肿瘤与面神经的黏连程度、肿瘤最大直径为患者术后7 d面神经功能障碍的独立危险因素（P=0.003、0.014）；术前临床症状持续时间、肿瘤最大直径为患者术后6个月面神经功能障碍的独立危险因素（P=0.010、0.030）。 结论肿瘤与面神经的黏连越紧密、肿瘤最大直径越大，患者术后7 d发生面神经功能损伤的可能性越大。患者术前临床症状持续时间越长、肿瘤最大直径越大，术后6个月发生面神经功能损伤的可能性越大。     

Comparison between self‐assembling peptide nanofiber scaffold (SAPNS) and fibrin sealant in neurosurgical hemostasis

RADA16‐I is a synthetic type I self‐assembling peptide nanofiber scaffold (SAPNS) which may serve as a novel biocompatible hemostatic agent. Its application in neurosurgical hemostasis, however, has not been explored. Although RADA16‐I is nontoxic and nonimmunogenic, its intrinsic acidity may potentially provoke inflammation in the surgically injured brain. We conducted an animal study to compare RADA16‐I with fibrin sealant, a commonly used agent, with the hypothesis that the former would be a comparable alternative. Using a standardized surgical brain injury model, 30 Sprague–Dawley rats were randomized into three treatment groups: RADA16‐I, fibrin sealant or gelatin sponge (control). Animals were sacrificed on day 3 and 42. Astrocytic and microglial infiltrations within the cerebral parenchyma adjacent to the operative site were significantly lower in the RADA16‐I and fibrin sealant groups than control. RADA16‐I did not cause more cellular inflammatory response despite its acidity when compared with fibrin sealant. Immunohistochemical studies showed infiltration by astrocytes and microglia into the fibrin sealant and RADA16‐I grafts, suggesting their potential uses as tissue scaffolds. RADA16‐I is a promising candidate for further translational and clinical studies that focus on its applications as a safe and effective hemostat, proregenerative nanofiber scaffold as well as drug and cell carrier.
