REGULATING FUNCTION OF COENZYMIZATION AND DECOENZYMIZATION OF THE LACTATE DEHYDROGENASE ISOZYMES IN THE MOUSE TISSUES DURING HYPOXIA

Objective. To study the characteristics of changes of LDH enzyme patterns of mice under slight hypoxia.Methods. Mice treated with artificial hypoxia, various tissues were made for the test of LDH enzymatic activity by the specific staining technique. LDH (1 -5) relative percentage enzymatic activity (RPEA) were measured with CS-910 dual-wavelength thin layer chromatography scanner.Results. The RPEA of LDH isozymes of various tissues after slight hypoxia shifted to the isozymes LDH1 and LDH2, whose principal subunits are H subunits, and the RPEA of LDH,(H4), LDH2(H3M) increased, while RPEA of LDH5(M4) in various tissues decreased prominently except the cardiac muscle, and that of LDH4(HM3) decreased as well. After polyacrylamide gel electrophoresis (PAGE) of the hypoxia treated cardiac muscle specimen was made, activity subbands originated regularly in the isozyme patterns of LDH, with the regularity of LDH1 (0 subband), LDH2 (0-1 subbands), LDH3 (0-2 subbands), LDH4 (1-3 subbands), LDH5 (2-4 subbands).     

6种中药制剂治疗急性脑梗死的成本-效果分析

目的：运用药物经济学的方法对在我院应用的6种中药注射液进行成本-效果分析。方法：271例急性脑梗死患者依据药物治疗方案不同分为6组，即血塞通组、舒血宁组、苦碟子组、疏血通组、川芎嗪组、丹红组，分别观察疗效，并运用药物经济学的方法进行成本-效果分析。结果：疏血通组的成本为3 419.90元，总有效率最高（91.84%），6组间增量成本-效果最低。因此疏血通组是较为合理、经济的方案。     

新华社区部分高血压患者危险因素分析

目的 了解本社区高血压患者的危险因素现状，探讨干预对策。方法 采用分层整群抽样的方法，随机抽取社区4个里委2级、3级高血压患者402例作为研究对象，收集各项危险因素如性别、年龄、血脂、血糖、吸烟、饮食、体育锻炼、体重等，并进行统计分析。结果402例高血压患者1年内进行所有相关辅助检查者有14例，占3．48％；1年内进行相关辅助检查一项者306例，占76．12％。饮食控制及进行体育锻炼有300例，占74．43％；吸烟62例，占15．42％。结论 高血压患者对饮食控制及体育锻炼、吸烟有害的知晓率明显提高，而对相关辅助检查认识不足。     

新生儿胃穿孔14例治疗体会

目的　探讨新生儿胃穿孔的发病特点和治疗方法。方法　对我院近 10年治疗的 14例新生儿胃穿孔进行回顾性分析。结果　 14例新生儿胃穿孔皆行手术治疗 ,术后死亡 7例。结论　新生儿胃穿孔多因先天性胃壁肌层发育不良及胃内张力增高缺血缺氧所致。早期诊断 ,及时手术 ,减少并发症及术后加强支持疗法是提高本病治愈率的关键     

细胞因子TNF-α和TSGF在恶性肿瘤中的检测价值

目的探讨肿瘤坏死因子-α(TNF-α)和恶性肿瘤相关物质群(TSGF)在恶性肿瘤中的诊断价值.方法采用酶联免疫吸附试验(ELISA)和化学法分别检测了67例恶性肿瘤患者,19例良性疾病患者和30例正常人血清中的TNF-α和TSGF的含量.结果恶性肿瘤患者血清中TNF-α和TSGF的含量均明显高于正常对照组及良性疾病组(P＜0.01).TNF-α的阳性率为85.07%,TSGF的阳性率为77.61%,两者总阳性率为92.54%.结论恶性肿瘤患者血清中TNF-α和TSGF的含量均明显升高,联合检测有助于提高恶性肿瘤诊断的灵敏度.     

SARS流行期间肺炎患者的临床表现和胸部影像变化的探讨

目的 探讨SARS流行期间肺炎患者的临床表现和胸部影像变化特点。方法 对76例SARS流行期间发热留观室收治的肺炎患者的临床表现及胸部影像进行分析。结果 (1)此组肺炎患者多为青壮年(占60．53％)，无固定职业或职业性质流动性较大者居多(69．74％)；(2)临床特征主要是发热，以中高热为多见(80．26％)，发病早期部分患者呼吸道症状并不明显(67．10％)，外周血WBC在正常或低于正常范围(85．53％)，淋巴细胞比例减少(75．00％)；(3)肺部CT表现为不同程度的炎性浸润；病灶形态以斑片状和球形多见(77．63％)；病灶常位于肺周边，常出现支气管气像；动态观察病变影像大多无明显进展(88．16％％)，经治疗均完全吸收。结论 SARS流行期间普通肺炎与非典型肺炎有相似的临床及胸部影像表现；肺部CT扫描能早期发现肺炎患者的异常阴影，明显优于胸片，但无特异性。因此，在SARS流行期间发热诊室医务人员应加强肺部炎性改变的早期诊断和鉴别诊断水平。

Hyperfractionated radiation therapy combined with concomitant chemotherapy for inoperable stage III non-small cell lung cancer: clinical analysis of 70 cases]

OBJECTIVE: To evaluate the effect of hyperfractionated radiation therapy and concomitant chemotherapy for inoperable stage III non-small cell lung cancer (NSCLC). METHODS: Seventy patients were randomized equally into two group. The therapy group received radiotherapy with hyperfractionated radiation therapy combined with concomitant chemotherapy, and the control group was treated with chemotherapy only. RESULT: The overall response rate, including the rate of both complete (CR) and partial responses (PR), in the therapy group was 60.0% with a CR rate of 8.6%. The overall response rate in the control group was 40.0% with a CR rate of 5.7%. The difference in overall response rate was statistically significant between the two groups (P<0.05). The median survival time, 1- and 2-years survival rate were 12.8 months, 48.6%, and 25.7%, respectively, in the hyperfractionated radiotherapy group, and 9.4 months, 34.3%, and 17.1%, respectively, in the chemotherapeutic group (P 0.031). The major toxic effects of the chemotherapy were myelosuppression and radiation esophagitis. CONCLUSION: Hyperfractionated radiation therapy plus concomitant chemotherapy with paclitaxel for inoperable stage III NSCLC improves the short-term response of the patients, but fail to raise the survival rate.
