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。     

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％。     

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.     

膀胱移行细胞癌中P16及Rb基因表达的关系

应用免疫组织化学方法对５９例膀胱移行细胞癌中Ｐ１６及Ｒｂ基因的表达进行研究。结果显示：５９例中Ｐ１６及Ｒｂ基因阳性表达率分别为４７４６％、７１１９％，其中１１例肿瘤组织（１８６４％）Ｐ１６及Ｒｂ基因均阳性表达，未发现同一肿瘤组织中同时存在Ｐ１６及Ｒｂ基因的表达缺失。Ｐ１６及Ｒｂ基因在膀胱移行细胞癌中的阳性表达率在肿瘤病理分级及临床分期的差异中均有显著性（Ｐ＜００５）。结果提示：Ｐ１６及Ｒｂ基因的异常表达在膀胱肿瘤的发生、发展过程中起重要作用，膀胱肿瘤中Ｐ１６及Ｒｂ基因同时表达缺失是少见现象     

前列腺带性结构及其雄激素、雌激素、表皮生长因子受体分布特征的研究

为了探讨雄激素受体（ＡＲ）、雌激素受体（ＥＲ）、孕激素受体（ＰＲ）和表皮生长因子受体（ＥＧＦＲ）在前列腺带性结构中的分布，应用单饱和剂量测定法，分别测定了前列腺移行带、外周带组织中ＡＲ、ＥＲ、ＰＲ和ＥＧＦＲ的含量。结果表明，在１１例前列腺增生症（ＢＰＨ）患者２２份标本中，移行带和周围带ＡＲ全部阳性；尽管ＡＲ浓度个体差异很大，但是两带之间仍有密切相关性（Ｐ＜０００１）；周围带ＡＲ浓度高于移行带，两带ＡＲ浓度均高于ＰＲ、ＥＲ；ＰＲ和ＥＲ在前列腺带性结构上没有明显差异。ＥＧＦＲ在移行带明显高于周围带。研究证实了ＡＲ、ＥＲ、ＰＲ，ＥＧＦＲ在前列腺移行带和周围带上的分布特征。     

人卵巢癌中肿瘤转移抑制基因nm23-H1编码蛋白的表达

目的：探讨人卵巢癌标本中，肿瘤转移抑制基因ｎｍ２３－Ｈ１编码蛋白ＮＤＰＫ－Ａ表达的临床意义及其与预后的关系。方法：应用免疫组织化学抗生蛋白链菌素－过氧化酶结合（Ｓ－Ｐ）法，检测５８例人卵巢癌标本中ｎｍ２３－Ｈ１蛋白水平。结果：ｎｍ２３－Ｈ１蛋白的表达与患者手术时是否有淋巴结及大网膜转移相关（Ｐ〈０．０５），但原发灶与转移灶间的阳性表达率相差不显著；与患者术后生存时间密切相关（Ｐ〈０．０１），术后生     

Hereditary characteristics of enzyme deficiency and dermatoglyphics in congenital color blindness

The hereditary characteristics of enzyme deficiency and dermatoglyphics in congenital color blindness (CCB) were studied. We propose that there is a linkage between the two loci on the X-chromosome determining CCB and glucose-6-phosphate dehydrogenase (G6PD), based on our study of a high incidence of G6PD deficiency in 156 male cases with CCB. The CCB gene is closely linked with that of G6PD deficiency from our pedigree investigations. The rise in the frequency of eight or more whorls, the low value of atd angle and the presenting rate of real palmar patterns of the thenar, hypothenar and I, areas presented the hereditary traits of congenital color blindness.
