目的 总结以双下肢乏力为主要表现的、合并低叶酸血症的患者的临床特征。方法 选择自2017年1月—2020年12月在我院神经内科住院的患者,分为3组：双下肢乏力伴叶酸缺乏组,共23例;叶酸缺乏合并脑血管病组,共129例;叶酸缺乏的健康体检者,为来我院行健康体检、无意中发现叶酸水平降低者,共42例,比较3组患者特征。结果 双下肢乏力伴叶酸缺乏组患者的发病年龄在19~88岁之间,平均（63.82±20.24）岁,男女比为2.3∶1。起病时间（13.34±17.88）d。与叶酸缺乏合并脑血管病组以及与叶酸缺乏的健康体检者相比,双下肢乏力伴叶酸缺乏组患者脑叶缺血灶数量较少,差异有统计学意义,P分别=0.001和0.008;与叶酸缺乏的健康体检者相比,双下肢乏力伴叶酸缺乏组患者放射冠和侧脑室缺血灶数量无变化,差异无统计学意义,P>0.05;与叶酸缺乏合并脑血管病组以及与叶酸缺乏的健康体检者相比,双下肢乏力伴叶酸缺乏组患者整体脑组织缺血灶总数较少,差异有统计学意义,P分别<0.01和0.05。结论 临床上遇到双下肢乏力患者,尤其是发病年龄在63岁左右,男性,起病时间在13 d左右,颅内整体缺血灶、尤其脑叶缺血灶较少的患者,需要警惕低叶酸血症所致双下肢乏力的可能。

Objective To summarize the clinical characteristics of patients with lower extremity weakness as the main manifestation and hypofolicemia．Methods Patients admitted in our neurology inpatient center from January 2017 to December 2020 were selected and divided into 3 groups．Group A consisted of 23 cases of bilateral lower extremity weakness combined with folic acid deficiency．Group B consisted of 129 cases of folic acid deficiency combined with cerebrovascular disease．Group C consisted of 42 healthy people with folic acid deficiency who came to our hospital for health check-up and found that the level of folic acid was decreased accidentally．The clinical characteristics of the three groups of patients were compared．Results The age of onset in group A was between 19 and 88 years old,with an average of（63.82±20.24）years old,and the male to female ratio was 2.3∶1．The onset time was（13.34±17.88）days．Compared with the group B and group C,the number of cerebral lobe ischemic area in group A was lesser,and the difference was statistically significant,P=0.001 and 0.008,respectively．Compared with group C,the number of corona radiata and lateral ventricle ischemic lesions in group A did not change,and the difference was not statistically significant,P>0.05．Compared with group B and group C,the total number of ischemic lesions in the overall brain tissue of group A was lesser,and the difference was statistically significant,P<0.01 and P=0.05 respectively．Conclusions When we encounter patients with bilateral lower extremity weakness in clinical practice,especially the average age of onset is around 63 years old,male,the onset time is about 13 days,and the overall intracranial ischemic lesions,especially the lobar ischemic lesions are less,we need to think of the possibility of bilateral lower extremity weakness caused by hypofolate．

目的 探讨罗伊适应模式对肺癌患者术后生活质量的影响。方法 将2012年3月—2015年7月来我院就诊的178例肺癌术后患者,随机分为试验组85例和对照组93例;对照组患者按护理常规进行护理,试验组在常规护理基础上给予罗伊适应模式护理干预;出院时分别比较两组患者住院适应性、治疗依从性、病人满意度及患者生活质量评分。结果 试验组住院适应率为87.1%(74例),对照组住院适应率为66.7%(62例),两组差异有显著性(P<0.01);试验组治疗依从性优良率为88.2%(75例)、对照组治疗依从性优良率72.0%(67例),两组差异有显著性(P<0.01);试验组患者满意度为89.4%(76例),高于对照组患者满意度73.1%(68例),两组差异有显著性(P<0.01);试验组生活质量评分,总体健康得分(74.1±8.3)高于对照组(56.7±5.9),且差异有统计学意义(P<0.01)。结论 罗伊适应模式护理干预,可以提高肺癌患者手术后的住院适应性、治疗依从性及病人满意度,显著改善患者生活质量,在临床推广罗伊适应模式护理干预具有现实意义。

Objective To investigate　the effect of Roy adaptation model on quality of life in patients for lung cancer after surgery. Methods 178 cases of　patients with lung cancer after surgery operation　were randomly divided into observation groups(85 cases) and control groups(93 cases). The control group was treated with routine nursing care and the observation group was treated on the basis of routine nursing care plus Roy adaptation model nursing interventions. When the two groups were compared in patients hospitalized and discharged adaptability, treatment compliance, patient satisfaction and patient quality of life score. Results Hospitalization adaptation in the observation group was 87.1%(74 cases) and control group was 66.7%(67 cases). There was statistically significant difference between two groups(P<0.01); Excellent treatment compliance of observation group was 88.2%(75 cases) and control group was 72.0%(67 cases). There was statistically significant difference between two groups(P<0.01); the observation group patient satisfaction were 89.4%(76 cases), it was higher than 73.1%(68 cases) of control group. There was statistically significant difference between two groups(P<0.01); quality of life in general health score(74.1±8.3) in the observation group was higher than that of control group(56.7±5.9),and there was statistically significant difference between two groups(P<0.01). Conclusion Roy adaptation model nursing intervention may improve the adaptability hospitalized the patients with lung cancer after surgery, treatment compliance and the patient satisfaction, and significantly improve the quality of life of patients. It is worthy of promotion clinically.

目的 初步探讨黄芩苷防治支气管哮喘的作用机理。方法 用卵蛋白致敏大鼠制备支气管哮喘动物模型,经黄芩苷干预治疗,运用免疫组化法及Western Blot法检测各组大鼠肺组织匀浆中p38 MAPK磷酸化蛋白表达量。结果 两种检测方法均显示,p38 MAPK磷酸化蛋白水平在模型组中有明显的增加,地塞米松组、黄芩苷高剂量组和低剂量组的p38 MAPK磷酸化蛋白水平均低于模型组(P<0.05)。结论 黄芩苷能有效治疗哮喘的作用与抑制哮喘大鼠p38 MAPK信号通路的表达密切相关。

Objective To explore the mechanism of Baicalin in treatment of bronchia asthma. Methods Animal models of bronchia asthma were made in rats sensitized with egg albumen. After the treatment of Baicalin, immunohistochemistry and western-blot methods were used to test expression quantity of phosphorylated p38 protein of lung tissue in all groups of guinea rats. Results Our data confirmed that the level of phosphorylated p38 protein increased significantly in model group, but it decreased in hexadecadrol group, high dose and low dose Baicalin group (P<0.05). Conclusion The effects of Baicalin in asthma model were associated with inhibition of P38 MAPK signal pathways in a dose-dependent manner.
