Prof. Ye Chuanhui''s Experience in Treating Nephritic Proteinuria

In the occurrence and development of glomerulonephritis, proteinuria is themain manifestation, which is easily recurrent but not easily got rid of in a short period of time. It may remain even after disappearance of the general symptoms. In some patients, there are no symptoms and signs at all in the initial stage, except proteinuria, the only distinct manifestation. Prof. Ye Chuanhui, from Chengdu University of Traditional Chinese Medicine, has accumulated rich experience for treating this disorder, which is introduced in the following.

二乙基亚硝胺诱导大鼠肝细胞癌过程中明胶酶的动态变化

目的：观察肝癌形成过程中明胶酶表达（蛋白及mRNA水平）的动态变化，探索明胶酶在肝癌生长浸润中的作用。方法：应用免疫组化法、明胶酶谱法和RT-PCR法对大鼠肝癌形成过程中各期明胶酶表达情况进行观察，并与正常对照组进行比较分析。结果：正常肝组织及肝硬化组织内明胶酶有表达，肝癌形成后主要在癌细胞内表达；明胶酶原在正常肝组织中有低表达，诱癌过程中呈持续增高趋势；明胶酶-2mRNA与其酶蛋白表达趋向一致。结论：在肝癌形成过程中明胶酶转录和翻译水平均呈持续增高趋势。     

ELISA法检测可溶性人类白细胞抗原—I及广东人参考值的测定

OBJECTIVE: To explore a method for quantitative detection of soluble human leukocyte antigen class I(HLA-I) antigens, with the assistance of which we attempt to define the reference value of the antigen in the population of Guangdong Province. METHODS: Sandwich enzyme-linked immunosorbent assay (ELISA) was employed with W6/32 monoclonal antibody serving as the solid phase antibody and beta2 microglobulin antibody as the first antibody. HRP-labeled second antibody and the substrate were added for enzyme-catalyzed coloring. On the basis of the standard curve obtained by sHLA-I standard reagent in serial dilution, the concentration of sHLA-I antigens in the samples of 60 normal subjects from the population of Guangdong province was detected. RESULTS: The sensitivity of this assay was 2.84 ng/ml with variation coefficients of 5.80% within the same batch and 9.00% between batches. The recovery rate ranged from 98.57% to 100.15%. The level of sHLA-I antigens in normal individuals was 699.54+/-360.10 ng/ml. CONCLUSION: Sandwich ELISA is sensitive, specific and stable in the detection of sHLA-I.     

青年急性冠脉综合征冠脉造特点及随访

目的:探讨青年急性冠状动脉综合征(ACS)冠状动脉(冠状)造影特点及其与远期心脏事件的关系。方法:比较青年ACS与老年ACS患者冠脉病变程度、范围,并进行心脏事件随访。结果:78例青年ACS患者有冠脉病变74例(94.9％),单支病变46例(58.9％);171例老年ACS患者有冠脉病变166例(97.1％),单支病变41例(23.9％)。平均随访9个月,青年ACS患者发生心脏事件者10例(12.8％),其中心绞痛再入院6例(7.7％);老年ACS患者发生心脏事件者47例(27.5％),其中心绞痛再入院30例(17.5％),两组比较差异有显著性(P<0.05)。结论:ACS患者冠状动脉粥样硬化青年时期之前已经发生,ACS预后与冠脉病变程度和年龄呈正相关。     

手工凝聚胺试验影响因素分析

目的分析各种因素对手工凝聚胺试验的影响；方法应用手工凝聚胺（manual polgbrene test，MPT）做交叉配血及抗体筛选试验；结果血液标本、操作手法、凝聚胺试剂、药物（肝素、止血敏、高浓度KCl等）等对试验均有影响；其中以药物、操作手法影响较大，可致假阴性和假阳性结果；结论手工凝聚胺试验做交叉配血及抗体筛选时应注意排除药物和操作手法对试验结果的影响。     

肾小球微血管构型的扫描电子显微镜观察

应用微血管铸型扫描电镜技术研究8例成人肾脏的肾小球微血管构筑,结果发现:1.输入小动脉在肾小球血管极处分为2～5支小球内小叶微动脉。输入小动脉血管铸型的直径为126.35±20.5μm。2.肾小球是由小球内小叶微动脉、毛细血管、毛细血管网小叶间交通支和毛细血管输出根所构成的近似于球状体,小球内每个毛细血管网小叶均是一个独立的机能解剖学单位;3.299个肾小球均有一支输出小动脉,只有一个肾小球有两支输出小动脉。输出小动脉的血管铸型直径为91.35±11.7μm。4.输出小动脉起始处具有毛细血管前括约肌装置,此结构在调控肾小球内的微循环血流有着重要意义。     

Ischemic rat brain extracts induce human marrow stromal cell growth factor production

Intravenous administration of human bone marrow stromal cells (hMSCs) after middle cerebral artery occlusion (MCAo) in rats provides functional benefit. We tested the hypothesis that these functional benefits are derived in part from hMSC production of growth and trophic factors. Quantitative sandwich enzyme‐linked immunosorbent assay (ELISA) of hMSCs cultured with normal and MCAo brain extracts were performed. hMSCs cultured in supernatant derived from ischemic brain extracts increased production of brain‐derived neurotrophic factor (BDNF), nerve growth factor (NGF), vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF). These neurotrophins and angiogenic growth factors increased in a post‐ischemia time‐dependent manner. The hMSC capacity to increase expression of growth and trophic factors may be the key to the benefit provided by transplanted hMSCs in the ischemic brain.

对218例女性乳癌术后进行了十年以上的随访观察。随访率为95.87％。术后总的十年生存率为54.87％。Ⅰ期为85.71％,Ⅱ期为53.09％。Ⅲ期为30.76％。阐明了术后疗效与妊娠哺乳,肿瘤部位,肿瘤大小,临床期别,淋巴结转移情况及病理类型有明显关系。讨论了手术方式对术后的影响,提示扩大根治术对Ⅰ、Ⅱ期乳癌并无明显优越性。     

An etiological and clinicopathological study of early syphilis in oropharynx]

OBJECTIVE: To investigate the characteristics of the early stage treponema pallidum infected tissue in ear, nose, oropharynx and larynx and to raise relevance ratio of syphilis in nose and oropharynx and enhance doctor's self-protection awareness. METHODS: The histopathologic characteristics were studied by using HE staining, Warthin-Starry (W-S) staining was adopted to examine the treponema pallidum(TP) in lesion issue and its exudates smear for 12 cases biopsy tissues of suspicious syphilis. The diagnosis was confirmed by venereal disease research laboratory (VDRL), rapid plasma reagin circle test(RPR), treponema pallidum hemagglutination test(TPHA) and fluorescent treponemal antibody-absorption test (FTA-ABS). Treat with curing syphilis methods which published by nation. RESULTS: In the 12 cases mucous membrane specimen, the squamous epithelium proliferated, neutrophilic granulocyte infiltrated, within inherent membrane generous plasmacyte and lymphocyte infiltrated. W-S staining: plenty of treponema pallidum were found inside mucous membrane epithelium and exudate smear. Serology examination: 11 cases VDRL(++++), 7 cases RPR (+), 11 cases TPHA(+), 1 case FTA-ABS(+). After systemic treatment, 11 cases are clinically recovered. All patients serology become negative. CONCLUSION: W-S staining method can directly demonstrate histopathologic characteristics in early syphilis, in intrinsic membrane numerous plasmacyte infiltration. Combining with specific syphilis serology examination could increase diagnosis rate of syphilis in nose and oropharynx.
