桡动脉取血进针角度的新方法

桡动脉取血操作在临床的应用越来越广泛,但其操作存在一定难度,尤其是呼吸系统疾病的老年患者因其动脉血管细滑,且需经常穿刺取血,有一定难度。我们在临床操作中摸索出一种新的进针方法,现报告如下。一、资料与方法1．一般资料呼吸系统疾病患者120例,取血150次,其中男78例93次,女42例57次,年龄37-89岁,平均年龄63岁。其中慢性阻塞肺32例67次,肺性脑病7例26次,支气管哮喘12例29次,肺癌17例28次。随机分为二组,每组穿刺75次。

获得性免疫缺陷综合征患者胃黏膜组织人类免疫缺陷病毒感染分析

Objective To investigate the distribution and amount of human immunodeficiency virus (HIV) infection in gastric mucosa from untreated acquired immune deficiency syndrome (AIDS) patients and highly active antiretroviral therapy (HAART) treated patients.Methods Thirty-five AIDS patients (14 untreated patients and 21 patients receiving HAART) and 10 HIV-1 seronegative patients with gastrointestinal symptoms were enrolled and examined by upper endoscopy.The labeled HIV-1 double-stranded cDNA probe was a PCR product corresponding to the LTR and gag gene of the HIV-1 genome.HIV in gastric mucosal tissues from AIDS patients was detected using in situ hybridization (ISH) and compared with that in peripheral blood mononuclear cells (PBMC).Results ① No obvious character was found in gastrointestinal symptoms,endoscopy examination and pathology results of AIDS patients.② The expression of HIV gene was mainly detected in the gastric mucosal mononuclear cell (MMC).Other cells were also observed with HIV expression including mucosal epithelial cells,gland epithelial cells and interstitial cells.③There was no difference in HIV expression between sinus ventriculi and gastric body.④ HIV gene expression from AIDS patients was (1.97±3.25)% in gastric mucosa,no difference in HIV gene expression between two groups (P＞0.05).⑤ HIV gene expression in PBMC smear from AIDS patients was (12.38 ± 9.17)%.HIV expreesion in PBMC from patients who had received HAART for 1-4 years were markedly lower than that from patients who had not received HAART (P＜0.05).Conclusions The gastric mueosa is one of HIV infected sites.The potential effect of HAART on the decrease of HIV infected cells in gastric mucosa was unsatisfactory.

慢性HBsAg携带者及非活动性HBV感染状态的病理学研究

目的观察临床诊断为慢性HBsAg携带者及病理诊断为非活动性HBV感染状态患者的临床病理特点。方法总结慢性HBsAg携带者41例、非活动性HBV感染状态患者65例的临床资料,通过HE、组织化学及免疫组织化学染色观察其肝穿刺组织切片的病理变化。结果慢性HBsAg携带者41例无明显异常的症状体征,各项肝功能检查基本正常;但肝穿组织病理检查仅有10例无明显病变,30例为轻度慢性乙型肝炎,1例为静止性肝硬化。非活动性HBV感染状态患者65例中,少数患者有较轻的肝功能异常改变;病理检查无明显炎症和纤维化。结论慢性HBsAg携带者主要是一组以轻度慢性乙型肝炎表现为主的患者,非活动性HBV感染状态患者也仅有轻度的肝功能异常;慢性HBsAg携带者及非活动性HBV感染状态是临床医师和病理医师对同一类病变的不同诊断用词,对其诊断应结合临床和病理资料综合判断。
