目的:探讨骨调素(OPN)和单核细胞趋化蛋白(MCP-1)在大鼠梗阻性模型中的表达及其在肾脏纤维化发病机制中的作用.方法:采用-单侧输尿管结扎制造梗阻性肾病模型,分别于造模后7 d、14 d取肾组织,应用HE染色观察肾脏病理改变,免疫组化方法检测肾组织畔OPN和MCP-1蛋白的表达,应用逆转录-聚合酶链式反应(RT-PCR)法观察肾组织中OPN mRNA和MCP-1 mRNA的变化.结果:OPN、MCP-1表达主要位于肾小管上皮细胞,随着梗阻时间的延长,肾组织中OPN、MCP-1蛋白和mRNA表达明显增加.结论:OPN、MCP-1蛋白和mRNA在梗阻性肾病大鼠肾组织表达明显增加介导炎症过程,参与肾间质纤维化.     

体外循环对TXB2／6—keto—PGF1α的影响

对１３例体外循环病人进行了观察，发现体外循环后ＴＸＢ２／６－ｋｅｔｏ－ＰＧＦ１α显著增高，表明体外循环使血小板受损，而血小板受损是体外循环后失血的主要原因之一。     

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.     

头皮脑回样病变畸形

目的提高对头皮脑回样病变畸形的认识和治疗水平。方法复习有关文献,对头皮脑回样病变畸形的病因、临床表现、诊断、分类和治疗进行了分析,采用切除后植皮或扩张头皮瓣修复治疗6例。结果6例病变切除彻底,随访无复发。其中2例植皮病例患者导致局部秃发,4例扩张头皮瓣修复外形满意。结论头皮脑回样病变畸形是一种罕见的头皮良性病变,头皮扩张术是修复治疗头皮脑回样病变的理想方法。     

原位肛门整形重建术的研究

目的：探讨改进的内外括约肌在原位肛门整形重建术中的应用及其手术效果。方法：改进包括：①肛门内括约肌改进为双层双环肌套；②肛门外括约肌改进为股薄肌采用“围巾式”环绕结肠末端一周，其远端剖为两条，一条缝合固定于耻骨韧带；另一条缝合固定于骶尾韧带，即为肛门外括约肌重建和外括约肌浅部和深部的重建。结果：38例术后肛门外形及功能和远期生活质量、生存率均更为满意。术后随访总优良率达94．73％；远期生存率达76．32％。结论：低位直肠癌Miles术后，同时行改进的内外括约肌原位肛门整形重建的效果是可行的，更接近正常的肛门解剖结构和生理功能。

Interleukin 17-Producing γδT Cells Increased in Patients with Active Pulmonary Tuberculosis

Although it has been known that y8 T cells may play an important role in the immune response to infection of Mycobacterium tuberculosis (M. tb), the mechanisms by which the T8 T cells participate in the innate and/or acquired immunity to tuberculosis (TB) have not been full elucidated. In the present study, 27 patients with active pulmonary TB and 16 healthy donors (HD) were performed. We found that proportion of IL-17-producing cells among lymphocyte was similar between TB patients and HD, whereas the proportions of γδ T cells in IL-17- producing cells (59.2%) and IL-17-producing cells in γδ T cells (19.4%) in peripheral blood were markedly increased in TB patients when compared to those in HD (43.9% and 7.7%, respectively). In addition, the proportions of IFN-γ-producing γδ T cells in TB patients were obviously lower than that in HD. Upon re-stimulated with M. tb heat-treated antigen (M. tb-HAg) in vitro, fewer IL-17-producing γδ T cells were generated from HD and TB patients, whereas IFN-γ-producing γδ T cells were increased in TB patients compared to that in HD. Our findings in TB patients and healthy human were consistent with other murine investigation that the IL-17- producing γδ T cells were main source of IL-17 in mouse model of BCG infection, suggesting that γδ T cells might be involved in the formation of tubercular granuloma in pulmonary TB patients, but need further identification.
