酸性氧化电位水消毒效果及安全性分析

目的研究酸性氧化电位水（EOW）对物体表面擦拭消毒的效果。方法对物体表面分别用酸性氧化电位水、75％酒精、84消毒液擦拭消毒前后,细菌采样培养,比较3种消毒液消毒效果,观察对皮肤及环境的影响。结果3种消毒液消毒率分别是81．8％、76．5％、84．8％,物品擦拭消毒前后对细菌的消毒效果差异有统计学意义（P〈0．01）,3种消毒液的消毒效果比较差异无统计学意义（P〉0．05）。酸性氧化电位水对皮肤和环境无影响。结论酸性氧化电位水使用安全、有效、环保,擦拭消毒可起到有效的杀菌作用。     

Prevalence of asymptomatic malaria parasitaemia

ObjectiveTo evaluate factors associated with prevalence of malaria parasitaemia at first antenatal care visit.MethodsThe study was conducted at the University of Calabar Teaching Hospital from 1st June, 2007 to 31st July, 2007. A structured questionnaire was administered to a total of 545 pregnant women that were recruited in this study after obtaining informed consent and two slides of thin and thick films were prepared for each participant.ResultsFive hundred and twenty (95.4%) out of the 545 participants suffered from malaria parasitaemia, the rest 4.6% of those who had no parasitaemia had experienced symptomatic malaria before and were treated in private hospitals prior to their recruitment into the study. All participants (100%) who did not have antimalarials had parasitaemia compared with 91.1% among those that had antimalarials. The proportion of moderate to severe parasitaemia was also significantly higher among the former. Besides, the difference in parasitaemia between primigravidae and multigravidae was statistically significant (P=0.000) too. Among the methods used for vector control, only insecticide treated nets (ITNS) was associated with significant reduction in the level of parasitaemia (RR =0.83).ConclusionMalaria parasitaemia at first booking is significantly higher in primigravidae and women who have no anti-malaria treatment. The use of safe and effective antimalarial treatment along with ITNs will significantly reduce the level of parasitaemia in pregnant women.     

蛋白磷酸酶2A的癌性抑制因子在肾透明细胞癌中的表达及其意义

目的探讨蛋白磷酸酶2A的癌性抑制因子（CIP2A）在肾透明细胞癌中的表达情况及其与临床病理指标的关系。方法利用免疫组织化学方法检测35例肾透明细胞癌组织和对应癌旁组织（距离肿瘤≥0.5cm）中CIP2A的表达水平,并将癌组织CIP2A表达水平与临床病理指标进行比较。结果肾透明细胞癌组织CIP2A表达的阳性率为82.9%（29/35）,明显高于癌旁组织的阳性率22.9%（8/35）,差异有统计学意义（P〈0.001）;pT3/pT4期肾透明细胞癌CIP2A表达水平高于pT1/pT2期（P=0.007）,有远处转移者CIP2A表达水平高于无远处转移者（P=0.006）。CIP2A表达水平和年龄、性别及淋巴结转移无关。结论 CIP2A在肾透明细胞癌中呈高表达,并与肿瘤的局部侵袭和远处转移密切相关。     

针刺结合水针治疗腰背肌筋膜炎临床观察

目的观察针刺结合水针治疗腰背肌筋膜炎的疗效。方法将98例患者采用抽签法随机分为针刺水针组及针刺组,针刺取穴方法相同,针刺水针组加压痛点穴位注射。结果与结论针刺水针组总有效率为96.6%,针刺组为75.0%,差异有统计学意义(P<0.01),说明针刺水针组疗效明显优于针刺组。
