从中医角度探讨多囊卵巢综合征的发生与肺胃的相关性

对于“多囊卵巢综合征”中医病位的认识,学者们众说纷纭,主要涉及肺、肝、脾、肾、胃、冲任等。本文对其病位在“肺”“胃”这一观点提出质疑,并以多囊卵巢综合征现代文献资料为主要研究对象,确定多囊卵巢综合征的病变脏腑,提取多囊卵巢综合征的主要症状,总结多囊卵巢综合征的核心病机,从而探究多囊卵巢综合征的病位,讨论本病的发生与肺胃的相关性,加深对多囊卵巢综合征的中医认识。

The RNA helicase, nucleotide 5'-triphosphatase, and RNA 5'-triphosphatase activities of Dengue virus protein NS3 are Mg2+-dependent and require a functional Walker B motif in the helicase catalytic core

The nonstructural protein 3 (NS3) of Dengue virus (DV) is a multifunctional enzyme carrying activities involved in viral RNA replication and capping: helicase, nucleoside 5'-triphosphatase (NTPase), and RNA 5'-triphosphatase (RTPase). Here, a 54-kDa C-terminal domain of NS3 (DeltaNS3) bearing all three activities was expressed as a recombinant protein. Structure-based sequence analysis in comparison with Hepatitis C virus (HCV) helicase indicates the presence of a HCV-helicase-like catalytic core domain in the N-terminal part of DeltaNS3, whereas the C-terminal part seems to be different. In this report, we show that the RTPase activity of DeltaNS3 is Mg2+-dependent as are both helicase and NTPase activities. Mutational analysis shows that the RTPase activity requires an intact NTPase/helicase Walker B motif in the helicase core, consistent with the fact that such motifs are involved in the coordination of Mg2+. The R513A substitution in the C-terminal domain of DeltaNS3 abrogates helicase activity and strongly diminishes RTPase activity, indicating that both activities are functionally coupled. DV RTPase seems to belong to a new class of Mg2+-dependent RTPases, which use the active center of the helicase/NTPase catalytic core in conjunction with elements in the C-terminal domain.     

Alpha-1-antitrypsin types and rheumatoid arthritis

Frequencies of alpha-1-antitrypsin (Pi) phenotypes were studied in 100 female and 100 male Swedish patients with classical rheumatoid arthritis and compared with the population frequencies. A significant increase of rare Pi types (MS, MZ, MF and SZ) was found among the patients. However, the increase concerned mainly Z heterozygotes and was more strongly pronounced in male patients. The M-subtypes showed no association with rheumatoid arthritis. Previous investigations of Pi types in rheumatoid arthritis have shown somewhat variable results. The results so far indicate, however, that an association between the Z allele and rheumatoid arthritis is likely to exist, while the evidence for a relationship between rheumatoid arthritis and other Pi alleles is considerably weaker.     

戴天章《广瘟疫论》温病辨治特色

戴天章是清代著名的温病学家,精通医理,尤擅瘟疫的诊治,推动了瘟病辨治理论的发展。现基于戴天章《广瘟疫论》,从首创瘟疫五辨、力辨寒瘟异同,创瘟疫五种治法,完善外感病腹诊法3个方面进行深入探讨,系统总结其瘟疫辨治经验及学术思想,这些内容不仅丰富了温病学理论,亦对现代温病的临床辨治具有重要指导价值。     

明代《伤寒论》研究对后世的影响

系统研究了明代《伤寒论》文献,指出明代《伤寒论》研究对后世的影响,主要表现在温病学说直接受其催化而趋于成熟,明刻本《伤寒论》为后世提供了研究依据,重编整理导致了后世编次方法之多样,学术论争深化了后世的《伤寒论》研究。认为明代是《伤寒论》研究史上承前启后的重要时期,明代的《伤寒论》研究影响并规定了清代乃至近代的《伤寒论》研究模式和水平。     

胃肠宁胶囊治疗肝胃郁热型胃脘痛的临床观察附:170例病例报告

对照观察了中药胃肠宁胶囊和三九胃泰治疗肝胃郁热型胃脘痛患者１７０例的临床疗效,结果治疗组（胃肠宁胶囊组）１０４例,显效率为７５．９６％,对照组（三九胃泰组）６６例,显效率为３６．３６％,二者比较有高度统计学意义（Ｐ〈０．０１）,表明胃肠宁胶囊治疗肝胃郁热型胃脘痛的疗效优于三九胃泰。通过治疗前后肝胃郁热主症及其引起的其它症状的比较及慢性浅表性胃炎病理诊断比较,结果表明,具有疏肝解郁,清热和胃降逆之功     

"脾虚"大鼠胃黏膜组织一氧化氮含量及补中益气汤的作用

目的：研究“脾虚”大鼠胃黏膜组织一氧化氮（NO）含量的变化及补中益气汤的作用。方法：采用Griess试剂法和紫外分光光度法检测胃黏膜组织的一氧化氮代谢产物（NO2^-和NO3^-）和过氧化亚硝酸（ONOO^-）。结果：大黄“脾虚”大鼠胃黏膜组织中NO3^-、iNOS及ONOO^-水平均低于正常大鼠，经补中益气汤治疗后能恢复到接近正常水平。结论：“脾虚”大鼠胃黏膜组织一氧化氮（NO）含量低于正常，补中益气汤能升高“脾虚”大鼠胃黏膜组织中NO的含量。
