香菇多糖注射液对慢性乙型肝炎外周血单个核细胞膜IL—2受体表达的影响

The effects of lentinan on peripheral blood mononuclear cell (PBMC) expression of IL-2 receptor in patients with chronic hepatitis B in vitro and in vivo were studied. The expression percentage of IL-2 receptor in 44 patients with chronic hepatitis before treatment was 36.74 +/- 7.74, which was lower than healthy subjects, and was 48.92 +/- 3.79 after 2 months treatment of lentinan, which was approximated the normal control. PBMC from 30 patients with chronic hepatitis B were cultured in vitro with or without lentinan. The percentage of expression IL-2 receptor was 12.81 +/- 2.62 without lentinan and was 35.70 +/- 4.87 in the presence of lentinan. The concentration of lentinan stimulating expression of IL-2 receptor was between 0.2 to 200 g.ml-1. The results suggest that lentinan stimulates expression of IL-2 receptor on PBMC, which is associated with the therapeutic effectiveness of lentinan treatment.     

白内障超声乳化吸出及囊袋内人工晶体植入术

为观察和评价超声乳化白内障吸出术的临床效果、特点、并发病及防治措施，对４１　眼白内障施行超声乳化吸出术及小切口（６ｍｍ）囊袋内人工晶体植入术，并以同期的白内障患者４１眼行现代囊外摘除及后房型人工晶体植入做对照。结果：术后６个月，视力≥１．０者占４３．９％＞０．８者占７０．７≥０．５者占９２．７％，均明显高于对照组（Ｐ＜０．００１），术后平均散光为１．０４±０．８１，１，低于对照组（Ｐ＜０．０１）。白内障超声乳化吸出并囊袋内人工晶体植入术的复明效果优于囊外摘除并后房型人工晶体植入术。

PTCA及支架植入术治疗心肌梗死并重症泵功能衰竭近期效果观察

OBJECTIVE: To evaluate the short-term therapeutic effect of percutaneous transluminal coronary angioplasty (PTCA) with stent implantation in the treatment of myocardial infarction with severe pump failure. METHODS: The clinical data of 73 patients receiving PTCA and stent implantation for myocardial infarction with severity pump failure were analyzed and grouped according the occurrence of complications, degree of the vascular lesions and the complexity of the surgical procedures. Preoperative and postoperative ventricular ejection fractions (LVEF) were compared in each case. RESULTS: The degree of vascular lesions and surgical complexity were not shown to relate to the occurrence of the complications. Except in cases complicated by chronic renal dysfunction, significant improvement was achieved in the patients 7 d after the operation (P<0.05), regardless of different degrees of vascular lesions and surgical complexity. CONCLUSION: PTCA with stent implantation is effective to improve the short-term cardiac function of patients with myocardial infarction and severe pump failure.     

口服谷氨酰胺颗粒对烧创伤患者的疗效及安全性分析

目的观察口服谷氨酰胺(Gln)颗粒对烧(创)伤及大手术患者的疗效及可能发生的不良反应.方法采用随机双盲、安慰剂对照法,将受试患者分为Gln组和对照组,每组60例,两组患者采用等氮、等热量的营养支持.Gln组口服或管饲Gln 0.5 g·kg-1·d-1,对照组使用同等剂量的安慰剂甘氨酸,疗程均为7 d.比较用药前后两组患者肠黏膜屏障功能、蛋白代谢、免疫功能、肝和肾功能的变化及不良反应等. 结果伤后两组患者血浆Gln浓度明显低于正常值,而血浆二胺氧化酶(DAO)活性、内毒素含量、肠黏膜通透性[尿乳果糖/甘露醇(L/M)]及尿氮排量均明显增高;但Gln组用药7 d后血浆Gln浓度与用药前比较增加38.04%(P＜0.01).Gln组血浆前白蛋白、转铁蛋白及白细胞介素2(IL-2)含量均显著高于对照组(P＜0.01),升幅分别为21.19%、51.11%、57.54%.血浆DAO活性、L/M比值、内毒素含量及尿氮排量明显低于对照组,降幅分别为47.26%、52.18%、22.22%、27.78%(P＜0.05或0.01).两组患者的血浆总蛋白、白蛋白、血尿常规及肝、肾功能在用约前后变化不明显(P＞0.05).用药后有少数患者出现轻微不良反应如恶心、腹泻和便秘等,2～3 d后自行缓解,两组间比较,差异无显著性意义(P＞0.05).结论口服Gln能显著提高患者血浆Gln浓度,明显减轻伤后肠黏膜受损程度,并能促进机体蛋白合成,降低蛋白分解,提高机体免疫功能,且临床应用无明显不良反应.     

小儿急性肺损伤的短期肺功能随访

Objective To study the pulmonary functions of pediatric ALI/ARDS(acute lung injury/acute respiratory distress syndrome) survivors. Method A prospective cohort study of all survivors of ALI/ARDS in the PICU of Beijing Children's Hospital was performed. Patients were divided into three groups(0-3 years of age,3 ～ 7 years of age, and over 7 years of age) and followed up three months after diagnosis. Results There were 36 survivors in total of 44 ALl patients, three patients lost follow-up, 12 died and 21 survived. Five survivors refused to participate in the study because of asymptomatic, and one was unable to participate because of lymphoma com-bined with sepsis. A total of 15 children completed the whole survey (11 patients were less than 3 years old, andfour were over 7 years of age). Twelve patients had no discomfort in their respiratory tracts. Three months after be-ing enrolled, the pulmonary functions of all children improved, especially in terms of tidal volume and respiratory compliance (P<0.05). Conclusions The abnormal respiratory symptoms and signs in most children disap-peared three months after discharge. Most survivors still have pulmonary dysfunction at 3 monthes after discharge, but better than discharge.
