肝脾舒合剂治疗肝热脾虚型便秘型肠易激综合征临床观察

目的:观察肝脾舒合剂治疗肝热脾虚型便秘型肠易激综合征(C-IBS)的临床疗效。方法:将60例肝热脾虚型C-IBS患者分两组,治疗组40例予GPS合剂治疗,对照组20例予莫沙必利治疗,疗程8周。观察两组临床疗效、主要症状评分和生活质量评分变化。结果:治疗组总有效率为90.00%,对照组为60.00%,两组比较差异有显著性意义(P<0.05);治疗后两组主要症状积分均有降低(P<0.05),且治疗组低于对照组(P<0.05);两组患者生活质量均有不同程度改善(P<0.05),且治疗组改善优于对照组(P<0.05)。结论:肝脾舒合剂能改善肝热脾虚型C-IBS患者临床症状,提高其生活质量。     

Memory response to manual acupuncture in chronic insomniacs: evidence from event-related potentials

Objective

To investigate the effectiveness and safety of manual acupuncture for memory loss and sleep quality in chronic insomniacs.

Methods

A total of 60 eligible participants were enrolled and randomized into either a treatment group or a control group, with 30 cases in each group. The treatment group was intervened by manual acupuncture whereas the control group was given sham acupuncture. In the two groups, the interventions were offered once every other day and three times a week, for 8 weeks in total. Before and after the treatment, Pittsburgh sleep quality index (PSQI) and eventrelated potentials (ERPs) were used to assess the patients’ sleep quality and memory, respectively. Meanwhile, adverse events were monitored and recorded.

Results

After 8-week treatment, both the treatment group and the control group showed a significant decrease in the PSQI global score (P<0.001, P<0.01), and the decrease in the treatment group was more significant than that in the control group (P<0.001). The intra-group comparisons of ERPs indicated that, the latencies of N1 and P3 were shortened and the amplitudes of N1 and P3 were increased in the treatment group after the intervention, and the differences were statistically significant (P<0.05, P<0.001); in the control group, there were no significant changes in the latency and amplitude after the treatment (P>0.05). The between-group comparisons of ERPs showed that the treatment group was more effective than the control group in shortening the latency of P3 (P<0.01).

Conclusion

Acupuncture can be a safe and effective treatment option for chronic insomnia coupled with memory impairment.

     

CCl4诱导的小鼠纤维化肝组织微小RNA差异表达谱及初步功能分析

 目的：应用微小RNA(miRNA)芯片技术研究miRNAs在四氯化碳（CCl4）诱导的小鼠纤维化肝脏中的差异表达谱,并基于基因本体论（gene ontology,GO)分析及信号转导通路分析发现差异miRNAs的主要功能。方法：实验分为正常组及模型组,皮下注射 CCl4复制小鼠肝纤维化模型;应用Agilent 小鼠 miRNA 寡核苷酸基因芯片检测各组肝脏miRNA表达谱。用随机方差模型t检验筛选2组间的差异miRNAs,并预测其靶基因。对靶基因进行GO分析及信号转导通路分析发现差异miRNAs发挥的主要功能。结果：正常组与模型组间共筛选出39个差异miRNAs,其中模型组较正常组上调的23个,下调的16个。GO分析及信号转导通路分析结果提示差异miRNAs可能调控的靶基因及其参与的生物学功能包括细胞的增殖与活化、细胞凋亡、细胞周期、细胞黏附、细胞迁移、炎症反应、转化生长因子β（TGF-β）/Smads信号转导通路、Wnt受体信号转导通路、蛋白代谢过程的调控等。GO分析发现关键的上调miRNA包括mmu-miR-322、mmu-miR-15b、mmu-miR-195、mmu-miR-200b、mmu-miR-214等,关键的下调miRNA包括mmu-miR-16、mmu-miR-130a、mmu-miR-101b、mmu-miR-30a和mmu-miR-30e等。对显著性GO与显著性信号通路所属的靶基因取交集,对网络中miRNA在网络中的调控地位进行评价,结果发现关键的上调miRNAs包括mmu-miR-200b、mmu-miR-322、mmu-miR-106b、mmu-miR-23a、mmu-miR-15b等,关键的下调miRNAs包括mmu-miR-16、mmu-miR-30e、mmu-miR-30c、mmu-miR-30a、mmu-miR-130a等。结论：纤维化肝组织miRNAs表达较正常肝组织发生明显变化;肝纤维化形成的各个环节,包括细胞的增殖与活化、细胞黏附、细胞凋亡、细胞迁移与分化、物质代谢、TGF-β信号通路等都可能受miRNAs的调控。     

体验式护理教学对提高中医专业学生人文素质的影响

目的:探讨体验式教学对中医专业医学生临床护理见习人文素质的影响。方法:选择有临床护理见习要求的一年级中医专业学生72名,随机分为2组,每组各36名,同期交叉进行为期2周的护理见习。第1周A组参与人文体验式教学、B组为传统带教式教学,第2周两组对换。学习结束予人文素质问卷测试。结果:学生普遍认为,体验式教学对提高医患交流和处理实际问题等综合能力有明显帮助;在人文关怀评分方面,体验式教学明显优于传统教学(P<0.05)。结论:体验式教学有助于培养医学生的人文素质,有效提高临床护理见习效果。
