慢性乙型肝炎患者血清α1微球蛋白检测的临床意义

目的：检测不同肝功能损伤情况下慢性乙型肝炎（CHB）患者血清α1微球蛋白（α1-MG）的水平,探讨采用α1-MG评价CHB患者肝功能的临床意义。方法：243例CHB患者分为肝肾功能正常组（n=94）、肝功能正常肾功能异常组（n=20）、肝功能异常肾功能正常组（n=100）和肝肾功能异常组（n=29）,同时选取健康体检者67人作为对照组,测定各组受试者血清α1-MG水平,同时测定谷氨酸氨基转移酶（ALT）、天冬氨酸氨基转移酶（AST）和碱性磷酸酶（ALP）等肝功能指标及血清肌酐（CREA）、尿素氮（BUN）等肾功能指标。采用免疫比浊法检测α1-MG水平,采用紫外-乳酸脱氢酶法检测ALT水平,采用紫外-苹果酸脱氢酶法检测AST水平,采用AMP缓冲液法检测ALP水平,采用肌氨酸氧化酶法检测CREA水平,采用紫外-谷氨酸脱氢酶法检测BUN水平。结果：与对照组比较,肝功能异常肾功能正常组患者血清α1-MG水平明显降低（P<0.05）,肝肾功能正常组和肝肾功能异常组患者血清α1-MG水平无明显变化（P>0.05）,肝功能正常肾功能异常组患者血清α1-MG水平明显升高（P<0.01）。按照α1-MG<10 mg·L^-1为判断肝功能异常的标准,肝功能异常肾功能正常组患者血清ɑ1-MG阳性率为36%,肝肾功能异常组患者血清α1-MG阳性率为24%;如以α1-MG<15 mg·L^-1为标准,则肝功能异常肾功能正常组患者血清α1-MG阳性率为68%。肝功能异常肾功能正常组患者血清α1-MG水平与肝功能指标ALT、AST和ALP呈负相关关系（r=-0.934,r=-0.916,r=-0.847,P<0.01）,且其数值随着肝损伤程度的加重而降低。结论：α1-MG检测在判断CHB患者肝功能方面具有一定的临床意义,但须排除肾功能损害引起的结果干扰。     

空洞型非小细胞肺癌的预后分析

Objective To explore the survival and prognostic status of the cavitating non-small cell lung cancer. Methods A total 42 surgically treated patients with cavitating non-small cell lung cancer were studied retrospectively. Kaplan-Meiei was used to analyze the relationship between the prognostic factors and survival time. The cavitaing non-small cell lung cancer were matched 1:2 to the patients with non-small cell lung cancer that there is no cavity in X-ray, for gender, age, histology, lymph nodes dissection, stage, and whether receiving chemotherapy. The two groups were compared using the Log-rank test. Results The overall 1, 3, 5- year- survival rates for cavitating non-small cell lung cancer were 76.2%, 28.6%, and 14.7%, respectively. The diameter of the cavity and lymph nodes status significantly influenced syrvivals. 1he overall syrvival between the two groups of patients showed no sig- nificant differences (P=0.075). But the factors of women(P=O.040), younger than 60 years(P =0.032), NO of the lymph nodes dissection group(P=0.046), and staging Ⅰ were significantly influenced 5-year survivals(P=0.048). Conclusion The diameter of the cavity and lymph nodes status were correlated with the survival. The carcinomatous cavity are important prognosis factors for the nan-retail cell lung cancer patients of younger than 60 years, negative of lymph nodes dissection and staging Ⅰ , but whether the carci- nomtous cavity are important prognosis factors for the non-small cell lung cancer patients of woman was not determined.
