提高中医临床疗效的科学学检讨(连载三)

中医学的生命力在于临床疗效 ,社会对于中医学的需要也在于临床疗效。提高中医临床疗效的科学学研究 ,要以中医基础理论为依据 ,以理、法、方、药一脉相承的辨证论治为前提。造成中医临床疗效下降的问题在于“三个脱节” ,即中医学与自身文化基础脱节 ,中医临床与辨证论治脱节 ,中药与中医临床脱节。中医学正处于行将消亡的边缘 ,也处在新的突破的前夜。实事求是地进行科学、历史的反思 ,中医学完全有可能走出百年困惑 ,得到振兴和发展。     

Flow-induced Expression and Phosphorylation of VASPin Endothelial Cells

1 Introduction It is well known that mechanical forces have important influence on endothelial cells, in particular, on cytoskeleton reorganization. VASP (vasodilator stimulated phosphoprotein) is a 46 KD actin associated protein. It is a member of Ena/VASP protein family and composed of EVH1, proline-rich and EVH2 domains. It is considered as an important component of the sub-cellular regions where remodelling of the actin cytoskeleton takes place, such as the front of spreading lamell…     

谈伤寒和温病的关系

《伤寒论》和“温病学”所讨论的内容皆属于中医外感病的苑畴，后世常以《伤寒论》论风寒性外感病，“温病学”论温热性外感病，使两者对峙起来，故一直困扰着中医外感病学的研究及其发展。自《黄帝内经》以来，外感病的病情表现和病因病机没有本质的改变，《伤寒论》及其以后的方药至今在外感温热病的治病中有效地运用着。形成《伤寒论》和“温病学”对峙的原因，一是人们将广义“伤寒”和狭义“伤寒”的概念相混淆；二是把《伤寒论》治疗方法上的某些局限性，误认为辨证理论体系及其内容上的缺限，《伤寒论》的六经辨证和“温病学”的卫气营血辨证、三焦辩证在中医的理论上来看，其本质是相通的，只是各自表述理论问题时的概念，范畴以及所运用的名词术语有一定的差别，因此，在定前提下推进“寒温统一”的研究，将是中医外感病学发展的切入点。     

中医现代化的再思考

1993年12月,本人曾在中国科协主办的《科技导报》上发表了“中医现代化的若干思考”一文。就中医(包括中医中药,下同)现代化的困惑、现代科学方法论的启示、中医现代化的近期任务与目标谈了自己的一些观点。去年召开的全国卫生工作会议上,中央明确提出了“中医现代化”的号召。为此在原有基础上谈一些进一步的看法,与同道讨论。     

Chronic neuroprotective effects of low concentration lithium on SH-SY5Y cells:possible involvement of stress proteins and gene expression

To investigate the molecular mechanism underlying the neuroprotective effect of lithium on cells, in this study, we exposed SH-SY5Y cells to 0.5 mmol/L lithium carbonate(Li2CO2) for 25–50 weeks and then detected the expression levels of some neurobiology related genes and post-translational modifications of stress proteins in SH-SY5Y cells. cDNA arrays showed that pyruvate kinase 2(PKM2) and calmodulin 3(CaM 3) expression levels were significantly down-regulated, phosphatase protein PP2A expression was lightly down-regulated, and casein kinase II(CK2), threonine/tyrosine phosphatase 7(PYST2), and dopamine beta-hydroxylase(DBH) expression levels were significantly up-regulated. Besides, western blot analysis of stress proteins(HSP27, HSP70, GRP78 and GRP94) showed an over-expression of two proteins: a 105 kDa protein which is a hyper-phosphorylated isoform of GRP94, and a 108 kDa protein which is a phosphorylated tetramer of HSP27. These results suggest that the neuroprotective effects of lithium are likely related to gene expressions and post-translational modifications of proteins cited above.     

百令胶囊对频繁发作 ＣＯＰＤ 病人免疫功能和肺功能的影响

目的：观察百令胶囊对频繁发作慢性阻塞性肺疾病（ＣＯＰＤ）病人免疫功能和肺功能的影响。方法： 选取 １００ 例年发作次数在 ２ 次以上，每次发作均来本院呼吸内科住院诊治的慢性阻塞性肺疾病急性加重期病人 （ＡＥＣＯＰＤ）。５２ 例对照组病人在常规治疗的基础上增加无创正压通气（ＮＩＰＰＶ），４８ 例观察组病人在对照组之 上增加百令胶囊治疗。观察两组病人治疗前后免疫功能和肺功能情况。结果：观察组临床治疗有效率为８３．３３％ 显著高于对照组的６５．３８％，有统计学意义（χ２ ＝ ４．１８，Ｐ＜０．０５）；观察组治疗后 ＦＥＶ１ 、ＦＥＶ１ 预测值、ＦＥＶ１ ／ ＦＶＣ 均 高于对照组，差异有统计学意义（Ｐ＜０．０５）；观察组治疗后 Ｔ 淋巴细胞亚群 ＣＤ４＋、ＣＤ４＋ ／ ＣＤ８＋高于对照组，ＣＤ８ ＋低于对照组，均有统计学差异（Ｐ＜０．０５）。结论：采用百令胶囊辅助治疗，可改善病人免疫功能，提高肺功能，有 望降低 ＡＥＣＯＰＤ 发作次数。     

科学地认识阴阳五行

20世纪里,在中医阴阳五行学说的存废问题上,中国文化界和医学界曾有过多次讨论。在全盘否定中国传统思想文化的客观环境中,每一次讨论都是由一个预定在先的“废”字为主导。所以每一次的所谓讨论,都留下了每一次的遗憾。     

Interleukin 28B-related polymorphisms: A pathway for understanding hepatitis C virus infection?

AIM:To analyze the role of rs12979860 and rs8099917polymorphisms in hepatitis C virus(HCV)genotype 1infection of Brazilians.METHODS:A total of 145 adult patients diagnosed with genotype 1 chronic hepatitis C(CHC)who had completed a 48-wk regimen of pegylated-interferonα-2a or-2b plus ribavirin combination therapy were recruited from six large urban healthcare centers and199 healthy blood donors(controls)from a single site between January 2010 and January 2012.Data on the patients’response to treatment was collected.Polymerase chain reaction-restriction fragment length polymorphism genotyping of the interleukin(IL)28B gene fragment encompassing the single nucleotide polymorphisms(SNPs)rs12979860(C/T)and rs8099917(T/G)was carried out for 79 of the CHC patients and 199 of the controls.Bi-directional amplicon sequencing of the two SNPs was carried out for the remaining 66 CHC patients.RESULTS:SNP rs12979860 genotyping was successful in 99.5%of the controls and 97.2%of the CHC patients,whereas the SNP rs8099917 genotyping was successful in 95.5%of the controls and 100%of the CHC patients.The genotype and allele distributions for both rs12979860 and rs8099917 were significantly different between the control and CHC patient groups,with significantly higher genotype frequencies of CC and TT in the controls(P=0.037 and 0.046,respectively)and of TT and GG in the CHC patients(P=0.0009and 0.0001,respectively).Analysis of the CHC patients who achieved sustained virological response(SVR)to treatment(n=55)indicated that the rs12979860 C allele and CC genotype were predictors of SVR(P=0.02).No significant correlation was found between rs8099917 genotypes and treatment response,but carriers of the T allele showed significantly higher rates of SVR(P=0.02).Linkage disequilibrium analysis of the group that achieved SVR showed a significant association between rs12979860 and rs8099917(P=0.07).CONCLUSION:The higher allele frequency of rs12979860 C and rs8099917 T observed in non-HCVinfected individuals may indicate a potential pro
