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.

广西边远少数民族学生体型及体质量指数3年追踪**

背景: 前期研究表明广西18~22岁少数民族学生体质量偏轻。 目的：拟进一步了解广西2645名少数民族学生体型及体质健康状况，寻找影响的关联因子。 设计、时间及地点：追踪调查，于2004-12/2007-12在广西民族大学完成。 对象：广西民族大学2003/2005三次体质健康测试的全体学生2 645人。男1 337人，女1308人，年龄为18~20岁，共15个民族。 方法：根据2003年教育部、体育总局《学生体质健康标准（试行方案）》和实施方法分为形态指标、技能指标和身体素质指标3大类。对2 645名少数民族身体机能与体质量指数变化的跟踪调查。 主要观察指标：身高、体质量、肺活量、立定跳远、坐位体前屈、体质量指数。 结果：①广西民族大学2003级学生大学3年期间男生身高、体质量增长率比全国同期多2.45%，身体形态发育正处于高峰期，女生成偏瘦型体型，身体形态发育情况总体欠佳。②男女学生在刚入校时肺活量机能较差，远远低于同期全国平均水平。3年后男生肺活量增长率为11.55%、女生肺活量增长率为27.72%，分别高于全国同期肺活量增长率。③坐位体前屈机能高于同期全国平均水平，男生呈逐年上升趋势，同期全国男性呈下降趋势；同期全国乡村女生均呈逐年上升趋势。④立定跳远机能提高较大，3年后增长率为18.15%，明显高于全国同期立定跳远增长率水平的2.61%。女生立定跳远机能总体不如全国同期水平。⑤体质量指数总体与同期全国乡村男女学生体质量指数比较稍低一些(P < 0.01)。 结论：2 645名少数民族学生发育正处于高峰期；肺活量机能不及全国同期平均水平。男女体质量指数分布有所不同，体质量偏轻者女生多于男生，表明学生营养状况总体欠佳。     

Performance and comparison of the Cockcroft-Gault and simplified Modification of Diet in Renal Disease formulae in estimating glomerular filtration rate in a Chinese Type 2 diabetic population.

AIMS: Our aim was to assess performances of the Cockcroft-Gault and simplified Modification of Diet in Renal Disease (MDRD) formulae in estimating glomerular filtration rate (GFR) in Chinese diabetic populations and their association with vascular risks. METHODS: A total of 1009 patients with Type 2 diabetes were categorized into low estimated GFR groups (GFR < 60 ml/min/1.73 m(2)) and control groups by the two equations. The performances of these formulae were assessed at different stages of kidney function. Carotid artery intima-media thickness (IMT) and the prevalence of diabetic retinopathy or albuminuria were compared among the groups. The ability of these formulae to identify established vascular risk markers using sensitivity, specificity, positive and negative predictive values were also compared. RESULTS: The prevalence of low estimated GFR was 32.7% with the Cockcroft-Gault formula and 5.2% with the MDRD formula, respectively. In low estimated GFR subjects by the MDRD formula, IMT was significantly thicker than those by the Cockcroft-Gault formula (1.2 mm vs. 1.0 mm; P < 0.05), with a higher prevalence of albuminuria (78.4 vs. 52.8%, P < 0.05) and diabetic retinopathy (46.5 vs. 30.5%; P < 0.05). The Cockcroft-Gault formula gave a specificity of 71.7% and a sensitivity of 37.0%, and the MDRD formula gave a specificity of 96.6% and a sensitivity of 7.9% in estimating low GFR relevant for established vascular risks. CONCLUSIONS: These formulae performed differently in Chinese diabetic populations. The simplified MDRD formula is minimally superior to the Cockcroft-Gault formula for its high specificity and positive predictive values in estimating low GFR relevant for vascular risks.     

应用前列腺素E1注射治疗勃起功能障碍8年经验

目的观察前列腺素E1(PGE1)注射治疗勃起功能障碍(ED)的长期疗效、副作用及预后。方法使用PGE1行阴茎海绵体注射,阴茎硬度检查仪(Rigiscan)连续记录1h,并根据观察结果,调查PGE1注射剂量,确定每例患者合适的注射量,掌握注射方法后回家自行注射。共筛选出ED患者410例,随访患者阴茎勃起情况、药量调整和副作用。结果410例ED患者中,心理性139例,静脉性83例,动脉性36例,神经性78例,混合性74例。对治疗满意的患者有256例(62.44%),其中21例(5.1%)在使用PGE15次后停用,并能达到满意的性生活而治愈。293例(71.46%)患者自述注射时有胀痛感。171例(43.17%)因疼痛(105例)、操作不便(25例)、副作用顾虑(37例)和其他原因(4例)而于6个月后放弃治疗。204例(49.76%)患者使用时间已超过1年,24例(5.85%)患者使用时间已超过5年,7例(1.7%)使用已有8年。未发现阴茎异常勃起和阴茎海绵体纤维化。注射损伤阴茎表面血管致瘀斑者有20例。有27例患者失访。结论PGE1是治疗ED的一种安全有效的药物,可以长期使用。其最常见的副作用是阴茎疼痛。Rigiscan能帮助确定PGE1的注射剂量。     

日本血吸虫酚氧化酶的组化定位研究

目的观察酚氧化酶(phenol oxidase,PO)在日本血吸虫成虫的组织学分布.方法酚氧化酶组化方法:将42 d虫龄的日本血吸虫活成虫置含25 mmol/L邻苯二酚的磷酸盐缓冲液(pH 6.8)中,37℃孵育30 min后,转移虫体至载玻片上,吸去虫体表面液体,将其中一部分虫体置Olym-pus显微镜下观察酚氧化酶在虫体的组织学分布.荧光组织化学方法:经上述过程处理后,在另一部分虫体上滴加2滴含0.05%戊巴比妥钠的PBS溶液,然后置Leica荧光显微镜下观察酚氧化酶在虫体的组织学分布.结果酶组织化学方法显示,日本血吸虫酚氧化酶仅分布于雌虫卵黄腺及子宫内虫卵卵壳表面,呈现棕褐色显色反应;雌虫卵巢和雄虫均未发现酚氧化酶活性.然而,荧光组织化学方法显示,酚氧化酶除主要分布于雌虫卵黄腺及子宫内虫卵卵壳表面,呈现强荧光外,还少量分布于雄虫体壁表层,呈现弱荧光反应.结论不仅日本血吸虫雌虫含有酚氧化酶活性,而且雄虫也含酚氧化酶活性,只不过其含量少、活性低.荧光组织化学方法能更灵敏地显示日本血吸虫酚氧化酶活性,更适用于日本血吸虫酚氧化酶的组织学定位.
