乙型肝炎表面抗原弱阳性结果探讨

目的探讨乙肝表面抗原(HBsAg)弱阳性的临床意义。方法用酶联免疫吸附法(ELISA)和时间分辨荧光免疫分析系统(TRFIA)分别对40例乙肝表面抗原(HBsAg)弱阳性标本进行检测。结果ELISA法测定40例弱阳性标本,经TRFIA法定量检测均为阳性。结论当检测HBsAg为弱阳性时,应进行复查确认。

《伤寒杂病论》“撰用《素问》《九卷》”考略

《伤寒杂病论》序言中有“撰用《素问》《九卷》”之语,由于书中很少发现有引用《素问》《九卷》原文的地方,因此后世一些学者对此表示怀疑。笔者认为,只要细心体会《伤寒》《金匮》两书的内容,仲景当日“撰用《素问》《九卷》”的痕迹,仍然是随处可见的。兹略陈管见,以与同道共商。     

ETIOLOGIC DIFFERENTIATION IN LOWER RESPJRATORY TRACT VIRUS INFECTIONS BY INDIRECT IMMUNOFLUORESCENCE

Of t,he 00 young children diagnosed clinically as having virus pueumonia, 24 (48%) had t.ype 3 0r 7 adenovirus antigen detected in exfoliated nasopharyngeal cells and Z of them also had the same viral antigen in the lung tissue which yielde{l type 7 adenovirus. Respiratory syncytial virus antigen was detected in 5 (10%). Type I, II or Ill parainfluenr.a virus ant.igen was detect- ed in 3 (67d and the same vira.l antigen was also detected in one of them in the hmg tissue vvhich yielded type I parainfluenza virus. OI the 7 infants diagnosed clinically as brouchiolitis, 3 had type 3 0r 7 adenovirus antigen detected in exfoliatcd nasopharyngeal cells and Z had respiratory syncytial virus antigen.' Type I, II or Ill parainfluertza virus antiger] jw:s detected in exfaliated nasopharyngeal cells in l child diagnosed clinically as having pleurisy. In 11 children with diseases over than respiratory tract infections, the results of detection of these 3 kiuds of viral antigens were all negative. Of the 30 cases ot virus pneumonia. a 4-fold or greater rise iri hemagglutination-inhibiting antibody titer to types 7 and 3 adennviruses was demonstrated in 39.5% antt 17.9%, tatallini: 53.8'lo; a 4-t'old or more increase in ucutralizing antihody titer to respiratory syncytial virus and a 4-fold or more increase in hemadsarption- inhibiting antibody titer to type I paraiufluenza virus were shcnvn in lO.3% eaeh. O~ the 5 cases ot bronchiolitis, 4-fold or greater rtses were shown in antibody titers, 1 case to type 7 adeno- virus, 1 to type 3 adenovirus and 2 to respiratory syncytial virus. No elevation of antibody titers to these 3 kinds of viruscs was obscrved in the 10 children with discascs otlier than respiratory tract inLections. There was gootlcorrespondence betweenthe detection of viralantigens by indirect im-munofluorescence andantibody titer assay inpaiFcd sera.     

生命科学家社会责任的特征和行为规范

生命科学家社会责任具有全人类性、全局性和全过程性的共同特征；国际组织和我国科研机构对生命科学家提出的伦理规范要求；诚信、奉献、创新、宽容、关怀、合作应是生命科学家最重要的伦理行为准则。     

颜德馨教授运用温阳法治疗心血管病经验

我国著名中医药家颜德馨教授，从事中医临床70余年，对中医心血管疾病具有独到的诊治经验，尤擅运用附子，今将其应用温阳法治疗心血管疾病的经验整理如下。1心血管病运用温阳法的依据 心居阳位，为清旷之区，主阳气，主血脉，依赖阳气鼓动、血液运行而维持其生理功能。如心阳不振，阳气失于斡旋，寒邪乘虚而入，两寒相得，凝滞气血，则血行不畅，瘀浊内阻，必然导致气虚血瘀，心脉痹阻，不通则痛。心体阴而用阳，心阳衰弱即心的正常功能衰退，其病机正如《金匮要略·胸痹心痛短气病脉证治篇》云：“阳微阴弦，即胸痹而痛，所以然者，责其撅虚也”。     

心脉通胶囊对急性冠脉综合征患者血清MMP-9与高敏CRP影响的临床观察

目的：探讨心脉通胶囊对急性冠脉综合征(ACS)患者抑制细胞外基质降解,减少炎症反应,稳定斑块的作用。方法：采用随机对照方法将ACS患者分为治疗组(对照组基础上加用心脉通胶囊n=31)、对照组(n=32),于治疗前后分别测定血清MMP-9与hs-CRP水平。结果：对照组MMP-9较治疗前有所下降但无统计学意义,而hs-CRP水平治疗后有显著性下降。治疗组MMP-9与hs-CRP水平均较治疗前明显改善,并明显优于对照组(P<0.05)。ACS患者MMP-9与hs-CRP水平呈正相关,而MMP-9,hs-CRP与血脂无相关。结论：心脉通胶囊可能通过抑制MMP-9,降低hs-CRP,而减少细胞外基质降解,减轻炎症反应达到稳定斑块的作用。     

眼镜王蛇毒鸡卵黄抗体的保护试验

目的:制备特异性高的鸡眼镜王蛇毒卵黄抗体,并对其进行体外和体内保护试验。方法:用眼镜王蛇毒免疫母鸡,在卵黄中产生抗眼镜王蛇毒抗体IgY,用水溶解法提取IgY,进行小鼠体外中和试验和体内保护试验。结果:体外、体内保护试验显示,6mg/kg的IgY可有效中和小鼠体内低剂量(≤3LD50)的蛇毒,对致死剂量蛇毒有很好的保护效应。结论:从卵黄中制备的抗眼镜王蛇毒IgY可有效地中和眼镜王蛇毒。
