目的 探讨特发性肺纤维化(IPF)患者和结缔组织病相关性纤维化间质性肺疾病(CTD-fILD)患者急性加重(AE)的短期内死亡的危险因素。方法 回顾性分析2017年10月—2019年9月在深圳大学和广州医科大学附属第一医院住院的25例 AE-CTD-fILD和26例AE-IPF患者临床信息,Kaplan-Merier法对两组患者进行生存分析,Cox回顾分析年龄、性别、吸烟、白细胞总数、C反应蛋白、红细胞沉降率及肿瘤指标在急性加重患者死亡中的作用。结果 与AE-CTD-fILD比较,AE-IPF患者组男性比例、年龄、吸烟比例较高,红细胞沉降率较低(24/26 vs 10/25,P<0.001;63.77±9.97 vs 58.00±10.32,P=0.048;16/26 vs 9/25,P=0.02;28.07±29.45 vs 64.35±40.34,P=0.002 );90天内,26例AE-IPF患者11例死亡,25例AE-CTD-fILD患者5例死亡,死亡率无明显差异(42.3% vs 20%,P=0.073);Cox回归分析显示,白细胞计数是AE-IPF和AE-CTD-fILD患者的死亡危险因素(HR=1.305,P=0.001;HR=1.529,P=0.009);CA15-3是AE-IPF患者死亡危险因素(HR=1.015,P=0.005)。结论 急性加重IPF和CTD-fILD患者短期内死亡风险相似,白细胞计数及外周CA15-3水平可能是肺纤维化急性加重患者短期内死亡的危险因素。

Objective To explore the risk factors for acute exacerbation (AE) in patients with idiopathic pulmonary fibrosis (IPF) and connective tissue disease associated with fibrotic interstitial lung disease (CTD-fILD). Methods We retrospectively reviewed 25 patients with AE-CTD-fILD and 26 patients with AE-IPF, and Kaplan-Merier was used to analyze the survival of the two groups of patients. The impact of age,gender, smoking,WBC,CRP,ESR and tumor markers on acute exacerbation death were performed by Cox regression analysis. Results The AE-IPF patients had a higher proportion of men,age and smoking,and a lower ESR compared with AE-CTD-fILD patients(24/26 vs 10/25,P<0.001;63.77±9.97 vs 58.00±10.32,P=0.048;16/26 vs 9/25,P=0.02;28.07±29.45 vs 64.35±40.34,P=0.002 ). 11 cases of 26 patients with AE-IPF and 5 cases of 25 patients with AE-CTD-fILD died within 90 days, Log-rank tests showed patients with CTD-fILD had similar mortality rate compared with IPF patients after AE(42.3% vs 20%,P=0.073). The WBC count was negatively correlated with survival and the independent predictors for patients with AE-IPF and AE-CTD-fILD after adjusting for other clinical variates in Cox regression models(HR=1.305,P=0.001;HR=1.529,P=0.009). CA15-3 may be a risk factor for death of AE-IPF patients(HR=1.015,P=0.005). Conclusion AE-CTD-fILD and AE-IPF were associated with similar poor short-term survival, WBC count and plasma CA15-3 may be the independent survival predictors respectively for patients with acute exacerbation of pulmonary fibrosis in short term.

目的 探讨雷公藤甲素防治大鼠青光眼术后滤过泡纤维化的可行性。方法 选取Wistar大鼠100只分为两组,对照组和观察组各50例。采用房水释放联合激光房角光凝法建立青光眼大鼠模型,然后所有大鼠均进行青光眼手术。手术后,观察组大鼠使用雷公藤甲素预防治疗青光眼术后滤过泡纤维化,对照组大鼠使用5-氟尿嘧啶预防治疗青光眼术后滤过泡纤维化。观察比较防治滤过泡纤维化效果。结果 观察组大鼠的眼压在手术后第1天与对照组相比无差异(P＞0.05),在第6天、14天低于对照组(P＜0.05),观察组大鼠滤过泡面积在手术后第1天、6天、14天均小于对照组大鼠(P＜0.05);观察组大鼠的治疗后滤过泡分型Ⅰ型和Ⅱ型均优于对照组,Ⅲ型和Ⅳ型均低于对照组(P＜0.05);观察组术后不良反应发生率为12.16%,低于对照组22.86%(P＞0.05)。结论 雷公藤甲素防治大鼠青光眼术后滤过泡纤维化效果明显,且安全性较高,值得临床广泛运用推广。

Objective To investigate the feasibility of triptolide in prevention and cure rats glaucoma surgery fibrosis. Methods 100 cases of Wistar rats were divided into two groups, with 50 cases in the control group and the observation group.Glaucoma rat model were built by aqueous release combined with laser photocoagulation, and all rats underwent glaucoma surgery. After surgery, the rats in the observation group were observed their triptolide preventive treatment in glaucoma surgery fibrosis, the control rats were observed their 5-fluorouracil preventive treatment in glaucoma surgery fibrosis.The effects of prevention and treatment of bleb fibrosis were compared. Results The intraocular pressure of rats in observation group in the first day after surgery compared with the control group has no significant difference (P>0.05), on the 6th、 14th day it was lower than the control group rats(P<0.05). Filtration area in the observation group on first, 6th day, 14th days after surgery, was less than the control rats(P<0.05); In the observation group, the type Ⅰ and type Ⅱ of filtering bleb were better than those of the control group, the type Ⅲ and type Ⅳ were lower than those of the control group (P<0.05);The adverse reaction rate was 12.16% in observation group, it was lower than the control group 22.86% (P<0.05). Conclusion Triptolide in prevention and cure of rats glaucoma surgery fibrosis is obvious, and high security. It is worthy of promotion.
