残胃癌的诊治探讨（附5例报告）

本文就宁夏医学院附属医院肿瘤外科1984～1994年6月收治的603例胃癌中的5例残胃癌患者，结合文献对其发病年龄，部位，发病率，生物学行为、临床表现、早期诊断以及残胃癌与胃大部切除术式的关系等进行了探讨，认为：1.以外科手术为主的综合治疗是残胃癌的治疗原则；2．定期随诊是早期发现残胃癌的关键，3．B-Ⅰ式吻合或Roux-en-Y式吻台取代B-Ⅱ式吻合，可避免十二指肠液返流入残胃，减缓残胃癌的发生。     

Reconstruction of the thumb and radial side of palm--a report of 6 cases

Since 1985, on the basis of anatomic study of dorsal pedal artery, thumb and radial side of palm reconstruction have been successfully performed in one stage by using opposite composite dorsal pedal flap including the second toe, the second metatarsal and the first toe web. Because they were all distributed by dorsal pedal artery and great saphenous vein, dissecting these tissues was not difficult. Good function and cosmetic appearance were achieved following reconstruction.

Hemoglobin constant spring defined by specific oligonucleotide hybridization and hemoglobin D Punjab (beta 121----Gln) in a Batak Indonesian family

A Batak Indonesian from North Sumatra with hemoglobin (Hb) D Punjab (alpha 2 beta 2 121----Gln) and hemoglobin Constant Spring (Hb CoSp) is described. The 24-year-old man did not have clinical symptoms, and his hematological indices were normal. However, he had a persistent slight elevation of fetal hemoglobin level. His mother and his brother were heterozygous for Hb D Punjab; his father had Hb CoSp trait. A sister did not have any abnormal hemoglobin. To show the exact molecular defect leading to the synthesis of Hb CoSp in this family, genomic DNA from the father was analyzed by hybridization with synthetic oligonucleotides. Genomic DNA was digested with Sst I and Hind III producing a 1.05-kb fragment from the 3' end segment of the alpha 2-globin gene, including the termination codon. Two nonadecamers were synthesized to serve as probes: one, entirely homologous to the normal 3' end of alpha 2A-globin gene sequence, including the termination codon TAA, the other different from it by a replacement of the T in the termination codon TAA with C, changing it to CAA, the codon for the amino acid glutamine. DNA from normal controls gave a positive signal with the normal alpha 2TAA oligonucleotide probe but negative with the alpha 2 CAA probe. The father of propositus who had Hb CoSp trait gave a positive signal with the normal alpha 2TAA oligonucleotide probe as well as with the alpha 2CAA oligonucleotide probe, showing him to be heterozygous for the alpha 2CAA-globin gene. This result shows that the Hb CoSp in the Batak family is indeed due to a replacement of T by C in the TAA termination codon of the alpha 2-globin gene changing it to CAA the condon for glutamine. This explains the resulting readthrough of the untranslated sequence of the mRNA.     

Effect of Cycloheximide on the Adaptive Response Induced by Low Dose Radiation

Human lymphocytes pre-exposed to 10 mGy or 50mGy of X-rays become less sensitive to subsequent large dose irradiation,exhibited lower rate of chromosome aberration than expected.This adaptive response could be inhibited by cycloheximide,a protein synthesis inhibitor for successive 2h period ranging from 0.5h before to 4h after the low dose exposure,indicating that the adaptive response was directly related with the protein synthesis.     

Graves病的发病与社会心理因素

对１０７例甲状腺机能亢进症患者和９１名正常人采用艾森克个性问卷及自编社会环境的调查显示：４６．９４％的患者起病前有负性生活事件发生，个性特征甲亢组神经不稳定型及掩饰性评分显著高于正常组，有显著性差异，此结果提示甲亢患者存在明显个性缺陷和负性生活事件，这些因素可作为甲亢发病的一种诱因。     

精神分裂症患者外周血淋巴细胞姊妹染色单体交换的初步观察

检测了18例精神分裂症患者和25例健康人的SCE频率,结果提示患者组SCE频率显著高于对照组,与年龄、性别、病程、临床类型、有无遗传家族史无明显相关。研究提示SCE频率增高似与疾病本身有关。     

西藏地区农牧民生活习俗与包囊虫病的关系调查

目的　探讨西藏地区农、牧民生活习俗与包囊虫病的关系。方法　自制问卷对 7个县 2 40个家庭 163 1名成员与包囊虫感染有关的生活习俗进行调查分析。结果　饭前便后洗手的人仅有 16 1%,餐具一般都用天然水洗 ,大部家庭用天然绵羊绒擦洗茶具。大多数人都喝过河溪水 ,池塘水 ,人人都吃半生不熟的肉 ,半数以上的吃生肉和生血肠 ,绝大多数人喝未经消毒的鲜牛、羊奶。 10 0 %家庭养狗 ,所有人员与狗、羊、牛、马接触密切。包囊虫病人占调查人数 0 43 %( 7/ 163 1) ,有典型症状者占 0 67%( 11/ 163 1)。结论　当地居民感染包囊虫与不良生活习俗有关
