垂黄清脉冲剂干预治疗冠心病稳定型心绞痛热毒痰瘀证患者NF-κB信号通路的研究

目的 探讨垂黄清脉冲剂对冠心病稳定型心绞痛（热毒痰瘀证）患者NF-κB信号通路的调控。方法 本试验研究方法采用单盲、随机、对照法，选取就诊于宁夏医科大学总医院临床诊断为冠心病稳定型心绞痛（热毒痰瘀证）患者94例，将其随机分入对照组48例和试验组46例。两组均给予内科常规西药治疗，对照组加服银丹心脑通软胶囊，试验组加服垂黄清脉冲剂，疗程为3个月。于治疗前、后记录患者的基本情况，并采集血清样本，用酶联免疫吸附测定法（Elisa法）检测血清中TNF-α、NF-κB、IL-6、ICAM-1、VCAM-1、ET-1、NO浓度水平进行对比，用SPSS22.0将数据进行统计学分析。结果 与治疗前比较，两组治疗后Gensini积分、血清中TNF-α、NF-κB、IL-6、ICAM-1、VCAM-1、ET-1浓度水平均较治疗前显著降低，NO浓度水平显著升高（P < 0.05，P < 0.01），其中试验组显著程度尤为明显（P < 0.01）。与治疗后对照组比较，试验组Gensini积分、血清中TNF-α、NF-κB、IL-6、ICAM-1、VCAM-1、ET-1浓度水平降低，NO浓度水平升高趋势更明显（P < 0.01）。结论 垂黄清脉冲剂治疗冠心病稳定型心绞痛（热毒痰瘀证）在改善患者症状；改善冠状动脉管腔狭窄程度；通过降低炎症标志物TNF-α、NF-κB、IL-6、ICAM-1、VCAM-1的水平，减小ET-1/NO比值，从而对NF-κB信号通路进行部分调控，以有效抑制或截断血管内皮的炎症级联反应过程，清除炎症损伤因素以及保护血管内皮功能等方面均有显著优势，临床疗效确切值得肯定和推广应用。     

Pathophysiology and management of sensitive skin: position paper from the special interest group on sensitive skin of the International Forum for the Study of Itch (IFSI)

The special interest group on sensitive skin of the International Forum for the Study of Itch previously defined sensitive skin as a syndrome defined by the occurrence of unpleasant sensations (stinging, burning, pain, pruritus and tingling sensations) in response to stimuli that normally should not provoke such sensations. This additional paper focuses on the pathophysiology and the management of sensitive skin. Sensitive skin is not an immunological disorder but is related to alterations of the skin nervous system. Skin barrier abnormalities are frequently associated, but there is no cause and direct relationship. Further studies are needed to better understand the pathophysiology of sensitive skin – as well as the inducing factors. Avoidance of possible triggering factors and the use of well-tolerated cosmetics, especially those containing inhibitors of unpleasant sensations, might be suggested for patients with sensitive skin. The role of psychosocial factors, such as stress or negative expectations, might be relevant for subgroups of patients. To date, there is no clinical trial supporting the use of topical or systemic drugs in sensitive skin. The published data are not sufficient to reach a consensus on sensitive skin management. In general, patients with sensitive skin require a personalized approach, taking into account various biomedical, neural and psychosocial factors affecting sensitive skin.     

改革开放以来中医药文化发展的演进与特点探析＊

中医药文化是中医药事业发展的根基和灵魂，社会主义文化建设的重要组成。本文考察改革开放40年以来中医药文化发展的演进过程，从“社会矛盾—政策方针—中医药文化发展”的中观视角，构建了中医药文化发展分析模型，发现中医药文化先后经历了资产化发展（1978年-21世纪初）、情景化发展（21世纪初-中国共产党第十八次全国代表大会（中共十八大）前后）、生态化发展（中共十八大至今）三个阶段，每个阶段中医药文化发展的策略、重点和面临的问题具有明显的不同特点。因此，本文提出以社会矛盾为导向，优化政策引导，构建中医药文化生态体系，从个人、社会和国家发展的不同层面采取多元双向发展路径，推进健康中国发展，提升文化自信，打造文化强国。     

Biomechanical behavior of brain injury caused by sticks using finite element model and Hybrid-III testing

Objective: To study the biomechanical mechanism of head injuries beaten with sticks, which is common in the battery or assaultive cases. Methods: In this study, the Hybrid-III anthropomorphic test device and finite element model (FEM) of the total human model for safety (THUMS) head were used to determine the biomechanical response of head while being beaten with different sticks. Total eight Hybrid-III tests and four finite element simulations were conducted. The contact force, resultant acceleration of head center of gravity, intracranial pressure and von Mises stress were calculated to determine the different biomechanical behavior of head with beaten by different sticks. Results: In Hybrid-III tests, the stick in each group demonstrated the similar kinematic behavior under the same loading condition. The peak values of the resultant acceleration for thick iron stick group, thin iron stick group, thick wooden stick group and thin wooden stick group were 203.4 g, 221.1 g, 170.5 g and 122.2 g respectively. In finite element simulations, positive intracranial pressure was initially observed in the frontal comparing with negative intracranial pressure in the contra-coup site. Subsequently the intracranial pressure in the coup site was decreasing toward negative value while the contra-coup intracranial pressure increasing toward positive values. Conclusions: The results illustrated that the stiffer and larger the stick was, the higher the von Mises stress, contact force and intracranial pressure were. We believed that the results in the Hybrid-III tests and THUMS head simulations for brain injury beaten with sticks could be reliable and useful for better understanding the injury mechanism.

外周血miR-150-5p、SOCS1 mRNA对类风湿关节炎“病”“证”诊断意义的初步探讨＊

目的 探讨类风湿关节炎患者外周血miR-150-5p、细胞因子信号抑制因子1（suppressor of cytokine signaling 1，SOCS1）mRNA的表达及对类风湿关节炎（Rheumatoid Arthritis，RA）疾病诊断、中医证型判断的意义。方法 纳入符合诊断标准的RA患者57例及健康对照组19例，根据《22个专业95个病种中医诊疗方案》有关RA的中医证候诊断标准，判断RA的中医证型。qPCR检测RA患者及健康对照组miR-150-5p、SOCS1mRNA的相对表达水平，同时检测血常规、肝功能、肾功能等常规指标。双荧光素酶分析方法判断两者是否存在靶向关系。统计分析miR-150-5p、SOCS1 mRNA对RA疾病的诊断意义及其与中医证型的相关性。结果 RA患者外周血miR-150-5p的相对表达水平下调，低于正常人群（t = -19.019，P < 0.05）；其表达水平随疾病活动度升高，有下降趋势；患者外周血SOCS1 mRNA的相对表达水平上调，低于正常人群（t = 5.333，P < 0.05）；其表达水平随疾病活动度升高，有上升趋势。MiR-150-5p与SOCS1 mRNA有靶向结合关系（P < 0.05）。通过AUC曲线比较，miR-150-5p的相对表达水平区分RA的敏感性及特异性分别为98.1%、92.1%（AUC = 0.972，P < 0.05）；SOCS1 mRNA的相对表达水平无法区分RA（AUC = 0.472，P > 0.05）。RA患者中miR-150-5p的相对表达水平低于3.06，RA患者风湿痹阻证、寒湿痹阻证的相对风险分别为8.33、250.00（P < 0.05）。结论 miR-150-5p、SOCS1 mRNA在RA患者中有差异性表达，且有靶向结合关系。miR-150-5p可能是RA的疾病诊断及中医风湿痹阻证、寒湿痹阻证证型诊断的潜在生物标志物。     

“龙虎交战”针法针刺八脉交会穴对偏头痛患者头痛天数及血清CGRP表达的影响＊

目的 观察“龙虎交战”针法针刺八脉交会穴对无先兆偏头痛（Migraine without aura，MO）患者头痛天数及外周血降钙素基因相关肽（Calcitonin gene related peptide，CGRP）表达水平的影响。方法 按照头痛程度将90例MO受试者区层随机分为治疗Ⅰ组、治疗Ⅱ组和对照组各30例。治疗Ⅰ组施以“龙虎交战”针法针刺八脉交会穴（外关和足临泣），治疗Ⅱ组施以平补平泻针法针刺八脉交会穴（外关和足临泣），对照组施以平补平泻针法针刺非经非穴点，每次留针30分钟，5次/周，共治疗20次。于治疗前、治疗结束4周后的随访分别记录三组患者头痛天数的变化情况以判定疗效，并采集患者治疗前、治疗结束4周后随访的肘部静脉血用ELISA法检测血清中的CGRP含量的变化。结果 ①各组治疗前患者的头痛天数无显著差异（Ｐ > 0.05），治疗Ⅰ组、治疗Ⅱ组和对照组治疗结束4周后随访的头痛天数较治疗前均显著降低（Ｐ < 0.05）；治疗Ⅰ组头痛天数的降低显著优于治疗Ⅱ组和对照组（Ｐ < 0.001），治疗Ⅱ组头痛天数的降低显著优于对照组（Ｐ < 0.05）；②3组治疗前CGRP的表达无显著差异，治疗Ⅰ组、治疗Ⅱ组治疗结束4周后随访CGRP的表达较治疗前均显著下降（Ｐ < 0.001），对照组治疗结束4周后随访CGRP的表达较治疗前差异无显著性（Ｐ > 0.05）；治疗Ⅰ组CGRP治疗结束4周随访的表达较治疗Ⅱ组和对照组均显著下降（Ｐ < 0.01），治疗Ⅱ组CGRP的表达较对照组显著下降（P < 0.01）。结论 ①八脉交会穴施以“龙虎交战”针法针刺能明显改善MO患者的头痛天数，同时降低MO患者血清CGRP的表达水平，这可能是针刺八脉交会穴治疗MO的机制之一；②非经非穴点的针刺效应无持续性，而八脉交会穴的针刺效应具有持续性；③八脉交会穴可以充分发挥复式针刺手法的治疗效应，提示我们在临床上治疗疾病时不仅要注意腧穴配伍，恰当的针刺手法更是提高临床疗效、事半功倍的关键。
