BACKGROUND Tracheobronchial tuberculosis(TBTB)is a common subtype of pulmonary *** diseases often obscure the diagnosis of senile *** To characterize senile patients with TBTB and to identify the potential causes of *** One hundred twenty patients with senile TBTB who were admitted to the Anhui Chest hospital between May 2017 and May 2019 were retrospectively *** were classified as diagnosed group(n=58)and misdiagnosed group(n=62).Clinical manifestations,laboratory results,radiographic data,and endoscopic findings were compared between the two *** Patients in the misdiagnosed group were most commonly diagnosed as pulmonary tuberculosis(non-TBTB,29/62,46.8%),general pneumonia(9/62,14.5%),chronic obstructive pulmonary disease(8/62,12.9%),and tracheobronchial carcinoma(7/62,11.3%).The time elapsed between disease onset and confirmation of diagnosis was significantly longer in the misdiagnosed group[median(first quartile,third quartile):6.32(4.94,16.02)mo vs 3.73(2.37,8.52)mo].The misdiagnosed group had lower proportion of patients who underwent bronchoscopy[33.87%(21/62)vs 87.93%(51/58)],chest computed tomography(CT)scan[69.35%(43/62)vs 98.28%(57/58)],and those who showed CT signs of tuberculosis[27.91%(12/62)vs 50%(29/58)]as compared to that in the diagnosed group(Plinical manifestations,or prevalence of comorbid chronic diseases(P>0.05).CONCLUSION Insufficient or inaccurate radiographic or bronchoscopic assessment was the predominant cause of delayed diagnosis of *** implementation and better interpretation of CT scan and early implementation of bronchoscopy can help reduce misdiagnosis of senile TBTB.

The control group received routine rehabilitation treatment, while the observation group received low-frequency head stimulation on the basis of routine rehabilitation treatment. The changes of dopamine (DA), norepinephrine (NE), serotonin (5-HT), NSE, ET-1 levels and mean blood flow velocity of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA) were compared in two ***:Before treatment, there was no significant difference in DA, NE and 5-HT levels in two groups. After treatment, DA, NE and 5-HT levels in the observation group were (192.23±22.71) ng/mL, (98.02±11.71) ng/L, (210.07±25.03) ng/L, and in the control group. the DA, NE, 5-HT levels were (147.06±17.02) ng/mL, (83.07±11.15) ng/L, and (171.88±20.45) ng/L, respectively. The DA, NE and 5-HT levels in two groups were higher than those before treatment, and DA, NE and 5-HT levels in the observation group were higher than those in the control group. Before treatment, there was no significant difference in NSE and ET-1 levels between the two groups. After treatment, the NSE and ET-1 levels in the observation group were (7.97±2.07) μg/L and (41.01±10.07) pg/mL, and the NSE and ET-1 levels in the control group were (10.38±3.02) μg/L, (58.46±15.02) pg/mL, respectively. the NSE and ET-1 in two groups were lower than those before treatment, and the NSE and ET-1 of the observation group were lower than the control group.

探索毛蕊异黄酮（Calycosin）对PM2.5介导炎症反应的作用以及其机制,小鼠肺泡上皮细胞MLE12培养基中加入0～1mmol/L Calycosin,24h后MTT检测细胞活性。MLE12细胞经Calycosin预处理1h后,加入PM2.5至终浓度25μg/cm^2,共同孵育24h后,3-（4,5-二甲基噻唑-2-基）-2,5-二苯基四唑溴化物（MTT）法检测细胞活性,实时定量PCR检测细胞中白介素IL-6和IL-8mRNA,酶联免疫吸附法（EliSA）检测细胞上清液IL-6和IL-8含量,免疫荧光染色检测p65表达。MLE12细胞经0～1mmol/L Calycosin处理12h后,检测p-AMPK含量。MLE12细胞经腺苷单磷酸激活蛋白激酶（AMPK）抑制剂Compound C（10μmol/L）预处理1h,再加入Calycosin 100μmol/L处理1h,最后加入PM2.5（25μg/cm^2）刺激,24h后进行细胞活性和炎症反应检测。结果显示：0～1mmol/L Calycosin对MLE12细胞活性无明显影响,而Calycosin浓度大于500μmol/L具有明显的细胞毒性。Calycosin可明显减轻PM2.5暴露对细胞活性的损伤,抑制PM2.5诱导的IL-6和IL-8mRNA表达以及IL-6和IL-8蛋白的释放,并呈剂量依赖性。50或100μmol/L Calycosin可明显抑制PM2.5诱导的p65由细胞质进入细胞核。Calycosin可增加MLE12细胞内p-AMPK含量,并呈剂量依赖性。Compound C可抑制Calycosin减轻PM2.5介导细胞毒性、炎症因子增加和NF-κB激活的作用。由此推断：Calycosin在体外通过激活AMPK通路,抑制NF-κB的激活从而减轻PM2.5诱导的细胞损伤和炎症反应。

有机-无机杂化钙钛矿太阳能电池被报道具有极高的功率转换效率,是下一代太阳能电池材料有希望的候选者,但其化学性质极不稳定,在高温高湿条件下易分解.本研究采用无机Cs阳离子取代CH_(3)NH_(3)PbI_(3)结构中的CH_(3)NH_(3)有机阳离子,利用第一性原理密度泛函理论,计算了未掺杂CH_(3)NH_(3)PbI_(3)钙钛矿和Cs阳离子掺杂钙钛矿的电子性质.结果表明,适当比例的Cs阳离子掺杂能够增强Pb-I的相互作用力,且Cs阳离子掺杂并未改变钙钛矿直接半导体的属性.Cs阳离子与Pb-I框架之间强的共价相互作用,导致Cs阳离子掺杂钙钛矿具有更加稳定的晶体结构.这项工作阐明了Cs阳离子掺杂钙钛矿材料高稳定性的潜在机理,可以为将来设计高效稳定的钙钛矿光伏材料提供一定的理论依据.

背景:中医药在治疗缺血性脑卒中痰热腑实证中具有丰富的经验和独特的优势,为深入挖掘中医药对该病的治疗靶点和治疗机制,建立稳定、可靠的缺血性脑卒中痰热腑实证病证结合动物模型是关键。目的:探讨缺血性脑卒中痰热腑实证大鼠模型的建立方法及评价体系。方法:采用随机数字表法将60只SD大鼠随机分为4组:空白对照组(n=12)、缺血性脑卒中组(n=18)给予普通饲料喂养25 d,病证结合组(n=18)、痰热腑实证组(n=12)给予高脂饲料喂养25 d;第26天,空白对照组、缺血性脑卒中组灌胃给予生理盐水,病证结合组、痰热腑实证组灌胃给予自体粪便混悬液,连续灌胃3 d(灌胃期间继续给予高脂饲料);灌胃结束后,缺血性脑卒中组、病证结合组采用线栓法建立缺血性脑卒中模型,记录各组大鼠饮食量、饮水量、体质量、体温、粪便性状、鼻分泌物、喉中痰鸣、舌象等表征变化。造模结束后24 h,进行神经功能缺损评分、舌象表征、血脂水平检测、脑组织及颈动脉形态学观察以及血清胃动素和生长抑素水平检测。结果与结论:(1)与空白对照组比较,病证结合组大鼠呼吸急促、精神萎靡、烦躁、行动迟缓,鼻周可见大量分泌物、可闻及厚重的喉中痰鸣,饮食量、饮水量下降,体质量、体温及舌下脉络评分升高,粪便粒数、Bristol评分及粪便含水率降低;血清总胆固醇、三酰甘油、低密度脂蛋白胆固醇及生长抑素水平升高,胃动素水平降低,神经功能缺损评分升高,颈动脉发生显著病理改变,脑组织显示明显缺血形态学改变。缺血性脑卒中组仅能造成缺血性脑组织病理改变,不能复制出痰热腑实证的证候特征。痰热腑实证组能复制出典型的中医证候特征,但不能构建出缺血性脑卒中的脑组织病理改变。(2)结果表明,高脂诱导结合线栓法及自体粪便灌胃的多因素复合造模方法,可建立缺血性脑卒中痰热腑实证病证结合动物模型。
