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.     

磁共振弥散加权成像结合三维乳腺数字化断层摄影钙化分数在乳腺良恶性钙化病变鉴别中的诊断价值

  目的  评估磁共振弥散加权成像（DWI）结合三维乳腺数字化断层摄影（DBT）钙化分数对于钙化征象在乳腺良恶性病变诊断的应用价值。  方法  回顾性分析我院118例行乳腺DWI检查和DBT检查的患者，DBT检查发现有钙化征象，其中乳腺癌患者51例，病理类型包括:浸润性导管癌、浸润性导管癌、导管原位癌、髓样癌、浸润性小叶癌、黏液腺癌；乳腺良性病变67例，病理类型包括:纤维腺瘤、腺病、导管内乳头状瘤。对所有患者DBT图像的钙化征象进行钙化评分并且测量相应病变区域的表观扩散系数（ADC）值，分析ADC值、钙化分数及二者联合在乳腺含钙化病变的诊断效能。  结果  乳腺癌组ADC值低于乳腺良性病变组，差异有统计学意义（P < 0.05）；钙化分数高于良性病变组，差异有统计学意义（P < 0.05）。ADC值对诊断乳腺良恶性病变的曲线下面积（AUC）为0.853，钙化分数对诊断乳腺良恶性病变的AUC值为0.855，采用Delong检验得出两种方法对诊断乳腺含钙化病变的良恶性诊断效能一致，差异无统计学意义（P=0.625）。两种方法（钙化分数+ADC值）的Logistic回归分析显示，两种方法相结合的AUC值为0.903，具有很高的诊断效能。将ROC曲线（钙化分数、ADC值、两种方法结合的预测概率）经两两Delong检验结果显示，两种方法结合的ROC与单一ROC的差异有统计学意义（P=0.041、0.022）。  结论  DWI与DBT钙化分数对于钙化征象在乳腺良恶性病变的鉴别诊断效能无差别，两种方法相结合的诊断效能显著高于单一方法，为乳腺含钙化病灶的诊断与鉴别诊断中提供了更加可靠的依据。      

基于医院信息系统的乳腺癌临床特征及中西医用药特征分析

目的 解析真实世界中乳腺恶性肿瘤患者的人群特征、诊断特征、中西医用药特征，为乳腺癌的临床防治提供参考。方法 采集2002年2月至2015年5月全国60家三级甲等医 院信息系统（Hospital Information System，HIS）中，出院诊断为“乳腺癌”的患者用药信息，采用SAS9.3统计软件，对人口学信息、诊断信息、医嘱用药信息等进行描述性分析。结果 39798例乳腺癌患者，平均年龄（50.93者，平均年龄）岁；多以门诊入院，入院病情以“一般”为主;合并疾病主要为高血压，骨肿瘤，联用西药以抑制肿瘤细胞增殖、治疗并发症、缓解放化疗不良反应为主；中医辨证以痰瘀互结证，气阴两虚证，肝气淤滞证，脾气亏虚证型最为常见，临床清热解毒剂、益气扶正剂，活血化瘀剂应用较多。结论 乳腺癌中西医结合治疗，联用药物广泛，临床治疗基本符合临床指南。     

从武汉抗疫看中医药文化认同与新的医学模式
