婴儿肝炎综合征63例临床分析

对我科1989-1990年中收治的婴儿肝炎综合征63例的临床表现、合并症、治疗等方面进行了分析。笔者认为婴儿肝炎综合征为一组临床症候群。病因诊断有其重要性。腹部B超检查有助于肝炎和胆道闭锁的鉴别,可作为常规检查方法。并认为用肾上腺皮质激素治疗有效。     

Polymyositis-dermatomyositis:25 years of follow-up of 50 patients disease course, treatment, prognostic factors

Therapeutic results were analysed in 50 patients, including 17 with polymyositis (PM) and 30 with dermatomyositis (DM). All patients were treated with prednisone (Encorton, Polfa) and 47% of patients with PM and 73% with DM required combined treatment with prednisone and cytostatic agents, mostly with cyclophosphamide (Endoxan G.D.R.). Long-term treatment monitored with the clinical status led to remissions persisting after treatment discontinuation in 17.6% of PM patients and 24.2% of DM patients. In 64.7% of PM patients and 57.6% of DM patients regression of the clinical signs of the disease was achieved but these patients required further treatment. No information was obtained on 5 cases. Four DM patients died. The cumulative 17-year survival rate of PM patients was 100%, and that of DM patients was 78.8% . In 45 follow-up cases, the mortality was 8.9%. Side effects of the combined treatment included most frequently mucosal candidiasis (22.2%), transient leucopenia (14.8%) and recurrent respiratory tract infections (11.1%). In 5 cases liver biopsy was done and histological examination disclosed moderate fatty, glycogen and vacuolar degeneration of the hepatocytes. The statistical analysis of prognostic factors such as the diagnosis of PM or DM, sex, age at disease onset, disease duration till diagnosis establishing and beginning of treatment, fever, dysphagia, circulatory and respiratory changes, leucocytosis nad ESR at the beginning of the disease showed that sex (female), older age at disease onset and respiratory system changes may be accepted as poor prognosis factors.     

竹荪深层发酵菌丝体对小鼠免疫功能的影响及其抗肿瘤作用

过对食药用真菌──竹荪深层发酵菌丝体提取液对小鼠免疫功能及S－180肿瘤细胞的作用观察，表明其发酵菌丝体可明显提高小鼠腹腔巨噬细胞的吞噬功能（P＜0．01），并显著增加免疫器官的重量（P＜0．05）；对小鼠S－180肿瘤的抑瘤率为40．63％。     

一次手术法对自制两段式种植体种植效果的实验研究

本实验用自制纯钛两段式种植体,以一次手术法植入到狗的下颌前磨牙区,观察5个月,结果表明,观察期间内牙龈无炎症,种植体稳固,X线片显示种植体周围无透射区,镜下可见种植体表面与牙龈之间形成上皮附着样结构,与骨组织之间大多呈骨性愈合。提示了两段式种植体有两种设计和手术方式可供选择。骨内部分在开放的环境中也可达到骨性愈合。     

用DIG标记的寡核苷酸基因探针杂交技术进行人轮状病毒VP7G血清型鉴定

目的：建立用地高辛（Ｄｉｇｏｘｉｇｅｎｉｎ，ＤＩＧ）标记的寡核苷酸基因探针鉴定Ａ群轮状病毒ＶＰ７Ｇ血清型的分子杂交技术，并应用该技术研究河南Ａ群轮状病毒的Ｇ血清型分布。方法：根据轮状病毒编码糖蛋白ＶＰ７的基因核苷酸序列，选择该基因高保守区序列中与ＶＰ７Ｇ血清型高度相关的核苷酸片段，人工合成，并用ＤＩＧ标记。在优选的杂交条件下进行杂交：结果：①Ｇ１、Ｇ２、Ｇ３和Ｇ４四种Ｇ血清型特异性寡核苷酸探针只与同血清型的轮状病毒参考毒株杂交，无交叉杂交现象。灵敏度和特异性达到放射性同位素３２Ｐ标记的水平。②１８８份经ＰＡＧＥ确定的轮状病毒阳性标本中，７９份（４２．０％）、３５份（１８．６％）、１５份（７．９％）分别与Ｇ１、Ｇ２或Ｇ３型探针杂交；未检出Ｇ４型；５６份（２９．８％）未能分型；３份分型特殊。结论：该Ｇ血清型分型技术具有高度特异性和灵敏度     

康泉合用地塞米松控制化疗所致的胃肠道反应

目的：比较康泉及康泉合用地塞米松预防急性白血病化疗所致的胃肠道反应的效果。方法：在同一方案的不同疗程，分别单用康泉或康泉合用地塞米松，随机对照，共观察１１０疗程。结果：康泉及康泉合用地塞米松对预防化疗所致急性呕吐有效率分别为６９．５％和９５．１％，有明显差异（Ｐ＜０．０１）；对于迟发性呕吐两组的有效率分别为７４．５５５％和９１．８３％，亦有明显差异。结论：康泉和地塞米松合用对控制急性和迟发性恶性呕吐优于康泉单用     

Photoinactivation of bladder tumor cells by methylene blue: study of a variety of tumor and normal cells

Human bladder cancer cell lines, J82, Yen-87, Shen-87 and Zoa-88, and murine bladder cancer cell lines, MBT-2 and M1660, were used as target cells for dye-sensitized photoinactivation study in using methylene blue. Normal fibroblast cells, FB-1 and FB8490, were used as control group. The cytoplasmic activity of lactic dehydrogenase, soft agar clonogenic assay, and in vivo tumor growth, survival rate and tumor taking rate with or without photoinactivation were monitored and compared between different cell lines. Efficacy of photoinactivation was time-related and more than 90 per cent of cytotoxicity could be obtained within 60 minutes of illumination. The plateau of cytotoxicity curve could be achieved after staining for 30 minutes by methylene blue under the same illumination time. Normal fibroblasts had the same features with cancer cells. Photoinactivation of tumor cells showed significant inhibition of tumor growth and tumor taking rate in experimental animals. Survival rate was also significantly prolonged in the animals with tumor cells receiving photoinactivation. These results suggest that methylene blue-sensitized photoinactivation may be useful as an adjuvant photochemotherapy for superficial bladder cancer.     

肿胀局麻技术的临床应用

目的探讨肿胀技术在体表外科手术中的应用价值。方法随机选择体表肿物与先天性畸形、体表瘢痕、乳房整形、脂肪抽吸、腹壁整形、除皱、隆胸、褥疮、面瘫及颅骨电烧伤等２３０例体表外科手术应用肿胀技术，成人１６４例，完全采用肿胀法局麻技术，儿童６６例，在全麻下应用肿胀技术。并与相应手术非肿胀法下施行进行了比较。结果脂肪抽吸术中利多卡因用量可达３０～６０ｍｇ／ｋｇ体重。肿胀技术具有易于进行解剖间隙的分离、减少术中失血、增强麻醉效果、增加手术安全性和术后恢复快等优点。结论肿胀技术可推广到体表外科手术中广泛应用，对儿童更为适宜，对减少输血造成的疾病具有重要意义。     

维生素E对老年小鼠脾细胞转化反应及心,脑脂褐质含量的影响

目的探讨维生素Ｅ对老年小鼠细胞免疫功能及心、脑脂质过氧化反应的影响。方法３月龄幼年小鼠和１８月龄老年小鼠各饲以含维生素Ｅ（ＶｉｔＥ）５００×１０－６和３０×１０－６饲料８周后，测定血清ＶｉｔＥ水平、脾细胞转化反应和心、脑脂褐质含量。结果饲以含５００×１０－６ＶｉｔＥ饲料的老年小鼠脾细胞对刀豆蛋白Ａ（ＣｏｎＡ）和脂多糖（ＬＰＳ）的反应及血清ＶｉｔＥ水平均较饲以含３０×１０－６ＶｉｔＥ饲料者显著增高（Ｐ值＜０．０１）；心、脑组织中脂褐质含量则明显降低（分别为Ｐ值＜０．０１及０．０５）。结论膳食中补充较高剂量ＶｉｔＥ后，能显著提高老年小鼠血清ＶｉｔＥ水平，增强脾细胞转化反应，并明显抑制心、脑脂质过氧化，减少脂褐质形成
