The relationship between functional capacity (FC) and cardiovascular risk factors (CVRFs) in senile patients after noncardiac surgery

The aim of the present study was to investigate the relationship between the number of cardiovascular risk factors (CVRFs) and functional capacity (FC) in the senile patients undergone noncardiac surgery. One hundred and eighty-two senile patients scheduled for elective noncardiac surgery were selected. According to the Duke activity status index (DASI), the FC of each patient was evaluated, and also their CVRFs were recorded. According to the number of CVRFs, the patients were ranked into different groups. The significant differences in FC between the groups^’ were identified using the analysis of variance. The examination showed that FC decreased with the increasing number of CVRFs. As a conclusion, we emphasize that with the increasing number of CVRFs, the FC of senile patients, i.e., their metabolic equivalents (METs) decrease. The occurrence of low FC and higher CVRFs is a common phenomenon in senile patients.     

A nationwide population-based study of migraine in Brazil

The aim of this study was to estimate the 1-year prevalence of migraine and the degree of the association of migraine with some sociodemographic characteristics of a representative sample of the adult population of Brazil. This was a cross-sectional, population-based study. Telephone interviews were conducted on 3848 people, aged 18–79 years, randomly selected from the 27 States of Brazil. The estimated 1-year gender- and age-adjusted prevalence of migraine was 15.2%. Migraine was 2.2 times more prevalent in women, 1.5 times more in subjects with > 11 years of education, 1.59 times more in subjects with income of < 5 Brazilian Minimum Wages per month, and 1.43 times more in those who do not do any physical exercise. The overall prevalence of migraine in Brazil is 15.2%. Migraine is significantly more prevalent in women, subjects with higher education, with lower income, and those who do not exercise regularly, independently of their body mass index.     

Abdominal complications of patients in the psychiatric department

This paper reported 114 cases of abdomen complication in inpatients of psychiatric department who be examined with ultrasonography. They amount to 4.19% of the total inpatients for the corresponding period (114/2723). Among them 36 cases (31.6%) relate to the special factors of psychiatric department, 4 cases (3.51%) did not said anything about abdominal pain when they suffering from diseases which are serious enough to fell abdominal pain for the common man. The author stressed that we must devote much attention to the physical examination for patients of psychiatric department.

对６０例精神病患者行双侧杏仁核、内翼前肢定向毁损术。术前后采用ＢＰＲＳ、ＧＡＦ量表评定，经统计学处理示Ｐ＜０．０１，差异有非常显著意义，一年随访总有效率７６．７％。     

干扰素治疗慢性乙型肝炎应答的因素探讨

目的:总结干扰素治疗慢性乙型肝炎的应答因素。方法:应用干扰素α-2b 300万u肌注,每天1次,连续3天,以后隔天1次,疗程3个月,治疗慢性乙型肝炎162例。结果:干扰素应答者78例,非应答者84例,应答率为48％。结论:干扰素治疗慢性乙型肝炎,对年轻、感染时间短、非母婴感染特别是有明确输血史者疗效较好:对抗-HBe阳性者疗效欠佳;其治疗过程中ALT正常与否可作为干扰素疗效的预测因素。     

Visual identification of bacterially contaminated red cells

There have been increasing numbers of reports of transfusion-acquired Yersinia enterocolitica bacteremia (including several fatal cases). Fifteen units of whole blood were inoculated with various concentrations of Y. enterocolitica serotype 0:3 and processed into AS-3 preserved red cells (RBCs). Consistent growth of the organism was found at inoculum concentrations greater than or equal to 10 colony-forming units per mL. In all 13 units of RBCs that supported the growth of Y. enterocolitica, a darkening in color (due to hemolysis and a decrease in pO2) was observed in the bag. The attached sample segments, which were sealed from the main unit, remained sterile and did not darken. This color change was apparent in all the contaminated units by Day 35, which was 1.5 to 2 weeks after the bacteria were first detected in cultures of the blood. Hence, by comparison of the color of the segment tubing with that of the unit itself, units grossly contaminated with Y. enterocolitica can be identified prior to transfusion. Moreover, review of photographs on file at the Centers for Disease Control revealed this dramatic color change in 2 units of blood that caused transfusion-transmitted sepsis (Enterobacter agglomerans and an unidentified gram-negative bacillus, not Yersinia sp.), which demonstrated that the color change was not limited to Y. enterocolitica. This method of visual identification of contaminated units of blood could decrease the incidence of posttransfusion bacterial sepsis.

不同病程尖锐湿疣IFN—γ、lL—2及lL—4水平的研究

目的 研究不同病程尖锐湿疣(CA)患者血清γ干扰素(IFN—γ)、白细胞介素-2(IL-2)及白细胞介素-4(IL-4)水平的变化在CA免疫发病机制中的作用。方法 采用双抗体夹心ELISA法，检测了60例不同病程CA患者血清IFN—γ、IL-2及IL-4水平。结果 CA患者组血清IFN—γ、IL-2水平明显低于健康对照组(P＜0．01)，而CA长病程组血清IFN—γ、IL-2水平明显低于CA短病程组(P＜0．01)；CA患者组血清IL-4水平明显高于健康对照组(P＜0．01)，而CA长病程组血清IL-4水平明显高于CA短病程组(P＜0．01)。结论 CA患者有Thl型细胞因子表达低下和Th2型细胞因子表达亢进，长病程患者更明显，患者Thl型细胞因子表达低下和Th2型细胞因子表达亢进在CA的免疫发病机制中可能起重要作用。     

IFN-γ对喉鳞癌细胞系(Hep-2)HLA表达的调节

应用流式细胞测量术、蛋白斑点杂交及Northern blot分析在蛋白和RNA水平研究了不同浓度γ-干扰素(IFN-γ)作用48小时及去除IFN-γ作用后48小时的喉鳞癌细胞系(Hep-2)细胞组织相容性抗原(HLA)的表达情况。发现不经IFN-γ处理的对照组的Hep-2细胞表达HLA-Ⅰ类抗原,不表达Ⅱ类抗原。加IFN-γ作用48小时后HLA-Ⅰ类抗原表达增强,与IFN-γ的剂量呈量效关系,HLA-Ⅱ类抗原可被诱导表达;Hep-2细胞HLA-B27位点基因表达mRNA增强,HLA-DRα位点基因可被诱导表达mRNA,而IFN-γ作用后HLA-A2位点基因表达mRNA的量无变化。去除IFN-γ48小时后HLA抗原及mRNA的表达水平均恢复至未经IFN-γ处理的对照组水平。IFN-γ对Hep-2细胞HLA-Ⅰ类基因B位点的调节作用强于A位点,提示在HLA基因导入肿瘤细胞进行基因治疗时,用易调节表达增强的HLA-B位点基因为宜。
