Primary tracheobronchial amyloidosis in China: Analysis of 64 cases and a review of literature

Primary tracheobronchial amyloidosis (TBA) is a rare pulmonary disease.A systematic review was performed on 64 cases of primary TBA in China and progress in the diagnosis and treatment of this disease is discussed.The Chinese biological and medical databases from 1970 to 2010 were searched and 75 cases of complete clinical and pathological data were identified.The clinical characteristics of the disease were summarized and longitudinal comparisons were made of diagnostic and treatment methods over time.The results showed that the morbidity associated with primary TBA has increased over recent years.The clinical manifestations were non-specific.Progressive dyspnea, cough and sputum were the most common symptoms.The percentage of patients undergoing computed tomography (CT) scan has increased over the years.The bronchoscopy and transbrochial lung biopsy (TBLB) were usually sufficient to establish the diagnosis.Treatment was reported for a total of 44 cases.Bronchoscopic Nd:YAG laser irradiation, argon plasma coagulation (APC) and drugs administration such as steroids and colchicines were reported to be effective in some patients.It is concluded that the demographic characteristics and clinical manifestations of primary TBA patients in China are largely consistent with findings reported in other countries.Dramatically more cases were reported in recent years, mainly due to the extensive application of bronchoscopy since 1990s.Chest CT scan provides important clues for the diagnosis of the disease.The definite diagnosis was confirmed by bronchoscopic findings and Congo red staining of biopsy specimen.Bronchoscopic Nd:YAG laser irradiation, argon plasma coagulation (APC) and drugs administration, such as steroids and colchicines were reported to be effective in some patients.     

冠心病稳定期血瘀证与冠状动脉病变特点的相关性

目的:探讨冠心病稳定期血瘀证及其兼证与冠状动脉造影Gensini评分的关系。方法:选取131例经冠状动脉造影证实的冠心病患者,记录其稳定期中医证候与血瘀证计分,并根据患者冠状动脉造影特点进行Gensini评分,分析其血瘀证及其兼证、血瘀证计分与其冠状动脉病变特点和Gensini评分之间的关系。结果:冠心病稳定期患者以血瘀证、痰浊证、气虚证最为多见,分别占64.9%(85/131)、63.4%(83/131)、64.9%(85/131)。血瘀证患者冠状动脉病变长度与Gensini评分的数值均高于非血瘀证者(P<0.05,P<0.01)。在血瘀证兼证中,血瘀兼痰浊患者的冠状动脉病变长度与Gensini评分的数值均高于非血瘀证者(P<0.05);血瘀证计分>9分的患者,其冠状动脉病变长度长于血瘀证计分≤9分的患者(P<0.05);冠心病稳定期患者血瘀证计分与Gensini评分无明显相关性(Pearson相关系数为0.104,P=0.241)。结论:血瘀证是冠心病稳定期患者的常见证候,血瘀证计分反映了患者血瘀证严重程度,稳定期患者的血瘀证计分与冠心病患者发病时冠状动脉病变严重程度没有相关性。     

Complementary and Alternative Medicine:Is It Possible to Be Mainstream?

真核表达BMP4成熟肽及其对iPS细胞的分化抑制作用(英文)

目的研究BMP4因子在诱导型干细胞(iPS细胞)培养过程中的作用和起作用的相关通路。方法通过RT-PCR的方法从小鼠的胎盘组织中扩增BMP4成熟肽,并且在其N末端连接IgK分泌肽,此融合的片段克隆至pPYCAG载体上。重组质粒pPYCAG-IgK-BMP4转染至293T17细胞中并进行嘌呤霉素的筛选。通过细胞免疫荧光和Western blot方法鉴定出表达BMP4的阳性克隆。为进一步检测上清中BMP4的生物活性,iPS细胞培养于含BMP4因子的细胞培养上清和LIF因子中,连续培养3代,并进一步观察细胞表型、三胚层细胞的分化潜能和多潜能相关基因的表达水平。结果 Smad1被分泌至上清中的BMP4磷酸化。当培养基中含BMP4同时加入LIF因子后,可以有效抑制iPS细胞分化。在此种方法培养3代后,不仅iPS细胞的表型可以有效维持,iPS细胞中多潜能相关的基因表达水平也未受到影响,同时这些iPS细胞仍具有向三个胚层分化的能力。结论 BMP4可高效表达在真核细胞中,有效地使培养iPS细胞保持其多向分化潜能。
