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.     

眼针治疗阵发性室上性心动过速120例的即时疗效观察

目的:观察眼针对阵发性室上性心动过速的即时疗效。方法:选择符合诊断标准的门诊患者120例,针其眼针穴区:心区和上焦区。针后30分钟描记心电图,计算心率,观察眼针对阵发性室上性心动过速的影响。结果:显效103例,占85.83%;有效9例,占7.5%;无效8例,占6.66%;总有效率93.33%.结论:眼针对阵发性室上性心动过速有较好的即时疗效。     

后SARS时期对公共卫生与健康的再思考

在人们印象中“公共卫生”是一个很模糊的领域，它比较形象的载体可能就是爱国卫生运动或预防接种。美国1932年提出的公共卫生的定义，对现在依然有指导意义：公共卫生就是预防疾病，延长寿命，通过有组织的社会共同努力来改变环境卫生，从而促进身体的健康，提高工作效率，控制社区传染病的流行，教育个人形成良好的卫生习惯，组织医护人员对疾病进行早期的诊断和预防性治疗。简而言之，“公共卫生”就是关注公众健康的科学。公共卫生学不能脱离临床医学，后是对某种疾病的个体的治疗，而前则着眼对某种疾病做群体防护。     

穿琥宁粉针雾化吸入治疗小儿呼吸道病毒感染疗效观察

小儿呼吸道感染是小儿科最常见的疾病，以咽炎、扁桃体炎、气管炎和肺炎多见。病原体以病毒感染为主。未经治疗有诱发心肌炎、脑炎的可能，应积极进行有效治疗。我们自2004年6月至12月应用注射用穿琥宁冻干粉剂雾化吸入治疗小儿呼吸道病毒感染58例，取得满意效果，现总结报告如下：     

Influence of serum protein on polycarbonate-based copolymer micelles as a delivery system for a hydrophobic anti-cancer agent.

A new micelle system formed from methoxy (polyethylene glycol)-b-poly (5-benzyloxy-trimethylene carbonate; MePEG-b-PBTMC 5000-b-4800) was investigated as a delivery system for the hydrophobic anti-cancer agent, ellipticine. The ellipticine was loaded into the MePEG-b-PBTMC micelles with a loading efficiency of 95% using a high-pressure extrusion technique. The ellipticine-loaded micelles have a spherical morphology and an average diameter of 96 nm. The anti-cancer activity of ellipticine was confirmed to be retained following formulation in the MePEG-b-PBTMC micelles. The extent of protein adsorption to the MePEG-b-PBTMC micelles was investigated by transmission electron microscopy, dynamic light scattering and gel filtration chromatography. Overall, the amount of protein both loosely and tightly associated with the micelles was found to be minimal and insignificant. The partitioning properties of ellipticine between an aqueous medium containing protein and the MePEG-b-PBTMC micelles were examined over a range of protein concentrations. Under physiologically relevant conditions, it was found that 61% of the drug remained within the micelle fraction while 39% was in the protein-containing aqueous phase. In addition, the in vitro drug release profile of ellipticine from the micelles was fit using a modified Higuchi model and found to be accelerated in the presence of protein. These studies demonstrate that although there are no significant interactions between micelle and protein, the properties of the micelle as a delivery vehicle may be strongly influenced by protein-drug interactions.     

西药对中医脉象的影响

笔者毕业后十余年中,临床上遇到心脑血管病人大部分正在应用西药治疗,中医讲究辨证论治,西药是否影响中医的辨证,临床上脉象是否随着西药运用而改变呢?中医脉象学是中医诊病、治病重要手段,望闻问切中“切诊”是主要组成部分。脉象变化是辨证论治重要依据,求证离不开脉象,组成脉象的主要因素及原因有:①脉位:脉动显现部位的浅深,脉位表浅为浮脉,深沉为沉弦;②至数:脉搏的频率,以一个呼吸周期为单位,一息脉来四~五至为平脉,一息六至为数脉,一息三至为迟脉;③脉长:脉动应指的轴向范围长短,越超三部脉象称为长脉,应指不及三部,但见关部或寸部者…     

我焗花螺献给你

想起吃饭，奶猪有时候高兴．有时候不高兴。 老头儿猪对她说过．挨饿的时候他总惦记自杀，因为他见到那势头，总觉得躲不过去。之所以后来还活着．是因为他想到要是不死，保不准哪天还能吃上碗红烧肉，死了可就板上定钉永远也吃不上了。老头儿猪因为这个崇高的信念咬牙切齿地养大了肉猪他爸肉猪他爸又养大了肉猪。肉猪是奶猪的男朋友，肉猪他爸和老头儿猪把肉猪叫肉猪，肉猪把奶猪叫奶猪，肉猪说：“这样好，听起来就胖乎乎香喷喷的”。
