目的 探讨影响本区肺结核发病的危险因素,为肺结核的防控提供参考依据。方法 采用频数匹配病例对照的研究方法,选自2012—2015年间,在本区居住的肺结核患者为病例组,按1∶1病例对照,在本区选择与病例组同性别、年龄相差<2 a的健康居民为对照组,用单因素Logistic分析及对多因素非条件Logistic 回归分析进行统计学分析。结果 肺结核发病的保护因素有文化程度的高低(OR=0.237,P<0.037),居住环境采光(OR=0.393,P<0.013),蔬菜水果类摄入(OR=0.748,P<0.021),蛋奶类摄入(OR=0.704,P<0.027)。肺结核的危险因素有工作环境是否接触粉尘(OR=2.984,P<0.001)是否吸烟(OR=1.537,P<0.020),是否饮酒(OR=1.110,P<0.041),结核病人接触史(OR=11.052,P<0.001),居住环境潮湿(OR=1.117,P<0.001)。最终被选入回归方程的因素为,文化程度、工作环境是否接触粉尘、结核病人接触史、居住环境潮湿、蔬菜水果类摄入,其OR值分别为0.471、8.945、17.652、14.268、0.234。结论 文化程度及蔬菜水果类的摄入为肺结核保护因素,工作环境接触粉尘、接触过结核病人及居住环境潮湿是肺结核的危险因素。

目的 探讨尼莫地平对无症状脑梗塞认知功能障碍的改善作用及安全性。方法 将80例无症状脑梗塞患者随机分为治疗组和对照组,每组40例,于治疗前及治疗后3月分别进行蒙特利尔认知量表(MoCA)、简易智能状态量表(MMSE)、画钟测验(CDT)评估,并比较2组的评分结果。结果 尼莫地平治疗后3月MMSE 评分为(26.35±3.26)分,MoCA评分为(25.53±4.31)分,CDT评分为(6.12±2.23)分,较对照组分别为MMSE 评分为(23.12±3.45)分,MoCA评分为(22.21±3.63)分,CDT评分为(4.35±2.61)分有改善,差异均有统计学意义(P<0.05)。80例患者中MoCA评测异常组在视空间与执行能力、延迟记忆、注意力及计算力、抽象思维等分项得分明显低于MoCA评测正常组(P<0.05)。结论 尼莫地平能有效改善无症状脑梗塞患者的认知功能,且安全性较高。

Objective To explore the role of nimodipine in improving cognitive function in silent cerebral infarction patients and its safety. Methods Eighty SCI patients were divided randomly into 2 groups.MMSE、MoCA and CDT scores were assessed before treatement and after 3 month of treatment.The results were compared between the 2 groups. Results MMSE、MoCA and CDT scores of Nimodipine group(26.35±3.26, 25.53±4.31, 6.12±2.23, respectively), improved when compared with the control(23.12±3.45, 22.21±3.63, 4.35±2.61,respectively),and the difference was statistical significance (P<0.05). The patients with abnormal MoCA had lower scores in several cognitive domains (visuospatial and executive abilities, delayed memory, attention and capacity of calculation, abstract thinking (P<0.05) compared with control group. Conclusion Nimodipine could improve effectively the cognitive function in SCI patients and with a higher safety.
