目的 研究老年慢性阻塞性肺病(COPD)患者血清IL-33水平与其病程分期的相关性。方法 选择60例老年COPD患者作为观察组,按病程分期分为稳定期组和急性加重组,另选择15例非COPD老年患者作为对照组;分别检测血清IL-33水平。结果 各组组间比较结果显示,AECOPD组和COPD稳定期组的血清IL-33水平均高于对照组(P<0.05),其中,AECOPD组的比COPD稳定期组的更高(P<0.05)。结论 血清IL-33水平在老年COPD患者中增高,急性加重期更明显,提示IL-33在老年人COPD发生、发展中可能起重要作用。

Objective To have relevant research between serum IL-33 level and the stage of disease in elderly patients with chronic obstructive pulmonary disease(COPD). Methods 60 elderly patients with COPD were selected as the observation group, who were divided into stable COPD group and AECOPD group. The other 15 patients with non-COPD were selected as the control group. The serum IL-33 levels were detected respectively. Results The comparison results between the groups showed that the serum IL-33 levels in the AECOPD group and the stable COPD group were higher than those in the control group(P<0.05), which was higher in the AECOPD group than in the COPD group(P<0.05). Conclusion Serum IL-33 levels were increased in elderly patients with COPD, the increase in acute exacerbation was more obvious, suggesting that IL-33 may play an important role in the occurrence and development of COPD in the elderly.

Objective To explore the prenatal care strategy of applying Chinese medicine dialectical care to promoting cervical ripening of full-term pregnant women with qi-blood deficiency and its clinical effect. Methods We chose 180 first-time, full-term pregnant women with single fetus cephalic presentation who were diagnosed as with qi-blood deficiency and then randomly divided them into three groups, 60 in control group with oxytocin and usual care; 60 in group of Chinese medicine dialectical care, which provided oral use of Chinese medicine and dialectical care after those women being admitted to hospital; 60 in blank group with usual observation and care. We did Bishop assessment of neck of uterus before and after treatment in these three groups, conducted qualitative test in FFN (Fetal Fibronectin), the secreta from vagina and neck of uterus, and observed delivery outcome as well as the influence to mother and child. Results Compared with control group and blank group, the group ofChinese medicine dialectical care was outstanding in terms of labor rate, vaginal delivery rate, and FFN test(P<0.05). Conclusion Chinese medicine dialectical care boosts cervical ripening of full-term pregnant women with qi-blood deficiency. It is helpful to increase natural labor rate, reduce high-risk delivery, and promote health of mother and child. Therefore it is worth to be popularized.

Objective To investigate feasibility of microbubbles enhanced ultrasound (MEUS) on the concentration of Evans blue (EB) in rabbit,stestis. Methods Eighteen sexually mature male New Zealand rabbits were divided into four groups randomly. Pulsed ultrasound irradiation and intravenous microbubbles injection were both applied in the microbubbles enhanced ultrasound group (MEUS), pulsed ultrasound irradiation and intravenous microbubbles injection were individually applied in the therapeutic ultrasound group (TUS) and the simple microbubbles group (MB). Injection of EB was applied in each group five minutes before the treatment.Concentration of EB in testis tissue was measured homogenated. Results The concentration of Evans blue(EB) in rabbit's testis in MEUS group was statistically higher than the other groups (P<0.05). Conclusion Microbubbles enhanced ultrasound (MEUS) can increase the concentration of Evans blue (EB) in rabbit's testis.

Objective To explore the research and analysis of temporomandibular disorder(TMD)patients' psychological states. Methods People diagnosed in the dental clinic were identified as target population.Totally, 88 patients with TMD were recruited as case control,whereas 92 normal people,92 patients with mental depression and 90 patients with dysphoria disorders were collected as control group.Questionnaire survey was carried out based on Symptom Checklist(SCL-90),Self-rating Anxiety Scale(SAS),Self-rating Depression Scale(SDS)and Eysenck Personality Questionnaire(EPQ). Correlations between TMD and psychological factors were assessed using the statistical methods. Results Compared with normal people,patients with TMD showed statistically significant diversity in SCL-90,SAS and SDS.In subgroup analysis of patients with TMD,patients with repeated disease history or advanced education degree presented significant variation in terms of depression and anxiety when compared with those with first diagnosed or lower education degree.Compared with patients with mental illnesses,patients with TMD showed significant lower score in depression and anxiety. Conclusion In TMD treatment we should not only adapt traditional physical therapy,medical therapy,corrective therapy and surgical treatment but also pay attention to psychological treatment to correct the patients' negative emotions,which may improve the symptoms and actively terminate disease process.

Objective To observe the effects of eleven acid testosterone combined with L-carnitine on curing idiopathic asthenospermia. Methods Retrospective analysed the clinical data of 386 patients with asthenospermia patients from November 2012 to June 2014 in our department.According to the standard,the patients were divided into mild A,moderate B,severe C in 3 groups,given L-carnitine treatment and given eleven acid testosterone combined with L-carnitine treatment.We observed effect of the two therapeutic methods for the treatment of idiopathic asthenospermia. Results The sperm PR were increased,In group A and group B patients after treated.The difference was statistically significant(P<0.05).In group C,the patients received the treatment of L-carnitine,the sperm PR has no obvious improvement,There was no significant difference(P>0.05).The patients received the treatment of eleven acid testosterone combined with L-carnitine the sperm PR significantly increased,the difference was statistically significant(P<0.05).The treatment efficiency of A,B,C group received L-carnitine were 47.6%,41.7%,18.9%,the total effective rate was 37.9%.The treatment efficiency of A,B,C group received eleven acid testosterone combined with L-carnitine were 52.6%,45.5%,34.7%,the total effective rate was 45.5%;There was no significant difference in group A and group B(P>0.05).The treatment efficiency in group C received eleven acid testosterone combined with L-carnitine group is obviously higher than that given L-carnitine group,the difference was statistically significant(P<0.05). Conclusion The curative effect of eleven acid testosterone combined with L-carnitine in the treatment of idiopathic asthenospermia is better than that of L-carnitine single drug treatment.

近年来的研究已经报道证实了白细胞介素-33(IL-33)及其受体ST2可以保护心衰病人因机械应力过度牵拉所导致的心肌细胞肥大、心肌纤维化的发生以及可溶性ST2受体可作为潜在的心脏机械超负荷生物标志物。而对IL-33与受体ST2在动脉粥样硬化过程中发挥的作用少有涉及。本文主要探讨的是IL-33和ST2对抑制Th1/Th2漂移从而影响到动脉粥样硬化的进展以及血浆中可溶性ST2受体蛋白升高的意义。

Recent study has reported that interleukin-33(IL-33) and its receptor ST2 could prevent cardiomyocyte hypertrophy and exaggerated interstitial fibrosis which is because of the over harmful biomechanical force in patients with heart failure and soluble ST2 receptors is the potential biomarker of cardiac biomechanical overload. But few studies mentioned the sort of IL-33/ST2 complex plays a role in atherosclerosis. The purpose of this article is to explore the IL-33 and ST2 could reduce a Th1/Th2 shift. Consequently, it may improve the development of atherosclerosis and significance of soluble ST2 receptor increased in plasma.

目的 探讨拉米夫定治疗对乙肝活动的肺结核病人抗结核治疗中的临床价值。方法 通过回顾性分析159例初治肺结核乙肝表面抗原(HBsAg)阳性、HBV-DNA定量阳性病人,所有病例在抗结核前查肝功能均正常,分为两组,治疗组:在抗结核及护肝治疗过程中,加用拉米夫定抗乙肝病毒治疗;对照组:没用任何抗乙肝病毒药物;分别在抗结核治疗前、治疗2周、4周及8周复查肝功能,对比两组间肝损发生率,及肝损发生时间及严重程度。抗结核治疗4周后复查HBV-DNA定量,对比两组间HBV-DNA定量下降例数。结果 治疗组的肝损发生率仅20.5%,对照组病人抗结核治疗后肝损的发生率为53.1%,两者间差异有统计学意义。治疗组肝损出现时间多为大于4周,而且多数是轻度肝损。治疗组出现肝损中断抗结核治疗的病例数低于对照组。抗乙肝病毒治疗后复查HBV-DNA定量降低例数高于对照组。结论 拉米夫定抗乙肝病毒治疗,能抑制乙肝病毒复制,降低乙肝合并肺结核病人的肝损发生率并减轻肝损严重程度,提高病人对抗结核药物的耐受性。
