急性烟雾吸入性肺损伤药物治疗的研究进展

烟雾吸入是火灾中受害者死亡的最主要原因.烟雾中的颗粒物、有毒气体、刺激剂以及窒息剂的共同作用,使肺部发生急剧的病理生理反应,造成急性肺损伤,进而导致人员大量伤亡.近20年来,对烟雾吸入性急性肺损伤的病理生理学机制有了比较清楚的认识,药物治疗方面也取得了较大的进展,本文对此作一综述.     

p53 gene in treatment of hepatic carcinoma： Status quo

Hepatocellular carcinoma(HCC)is one of the 10 most common cancers worldwide.There is no ideal treatment for HCC yet and many researchers are trying to improve the effects of treatment by changing therapeutic strategies.As the majority of human cancers seem to exhibit either abnormal p53 gene or disrupted p53 gene activation pathways,intervention to restore wild-type p53 (wt-p53)activities is an attractive anti-cancer therapy including HCC.Abnormalities of p53 are also considered a predisposition factor for hepatocarcinogenesis.p53 is frequently mutated in HCC.Most HCCs have defects in the p53-mediated apoptotic pathway although they carry wt-p53.High expression of p53 in vivo may exert therapeutic effects on HCC in two aspects(1)High expression of exogenous p53 protein induces apoptosis of tumor cells by inhibiting proliferation of cells through several biologic pathways and(2)Exogenous p53 renders HCC more sensitive to some chemotherapeutic agents.Several approaches have been designed for the treatment of HCC via the p53 pathway by restoring the tumor suppression function from inactivation,rescuing the mutated p53 gene from instability,or delivering therapeutic exogenous p53.Products with p53 status as the target have been studied extensively in vitro and in vivo.This review elaborates some therapeutic mechanisms and advances in using recombinant human adenovirus p53 and oncolytic virus products for the treatment of HCC.

Fifty Years of Pacemaker Advancements

A 1957 power blackout in Minnesota prompted C. Walton Lillehei, MD, a pioneer in open heart surgery, to ask Earl Bakken, the co-founder of Medtronic, Inc., to create a battery-operated pacemaker for pediatric patients. That conversation led to the development of the first external battery-operated pacemaker. That first bulky device is far removed from the tiny implantable computers available to heart patients today. Now, the size of two silver dollars stacked on top of one another, a pacemaker is prescribed for a person whose heart beats too slowly or pauses irregularly. Slightly larger devices have more recently evolved from pacing and regulating the heartbeat to being able to provide therapeutic high voltage shocks when needed to stop runaway fast heart rates, recording heart activity, and other physiologic functions, even resynchronizing the heart’s chambers—all while providing information on the patient’s condition and device performance to the doctor remotely or in the office.     

肺动脉高压的研究进展

肺动脉高压是以肺血管阻力进行性增加为临床特征的一组威胁生命的疾病，近10年来，肺动脉高压的研究取得了显著的进展，涉及2003年威尼斯会议修改的肺动脉高压的命名和分类、遗传基因的发现、应用分子生物学技术探讨其发病学以及内科和外科治疗效果的改善。前列环素及其类似物和内皮素受体拮抗剂的临床研究，使肺动脉高压在治疗的安全性和有效性方面均取得了长足的进步。     

Review of advances in diagnosis and treatment of pulmonary tuberculosis

There has been a substantial leap in our understanding and the management of tuberculosis over the past couple of decades. New diagnostic tests, regimens and drugs have emerged. With a background of milestones in the management of tuberculosis, we review the advances made in the diagnosis and treatment of pulmonary tuberculosis. Since India accounts for 27% of word's burden of tuberculosis, the changes in RNTCP have been highlighted.     

脂联素在肺癌中作用的研究进展

脂联素是脂肪组织分泌的一种脂肪细胞因子,具有抗炎、抗动脉粥样硬化、调节糖脂代谢、增强胰岛素敏感性的作用,当前在肿瘤中的作用越来越受到重视。最新研究表明,脂联素在肺癌中呈低表达,在晚期肺癌中更明显。脂联素水平与肿瘤的侵袭性和转移性有关,可作为评估肺癌患者病情进展的重要参考指标,为肺癌的治疗提供新的干预靶点和治疗思路。现就其在肺癌中的研究进行综述。     

基质金属蛋白酶-9与肝纤维化关系的研究进展

肝纤维化是由于基质金属蛋白酶(matrix metalloproteinases,MMPs)及其组织抑制因子(tissue inhibitor of metalloproteinasas,TIMPs)比例失调,造成细胞外基质大量沉积在细胞间质中,引起的病理改变。目前研究发现MMP-9在肝纤维化形成过程中有诱发和促进作用,但也有一些相反的意见,认为其具有逆转肝纤维化的作用,与肝纤维化呈负相关。因此,本文就近年来对MMP-9功能的研究作一概述。     

治疗多囊卵巢综合征药物作用通路及靶点的研究进展

多囊卵巢综合征（PCOS）是育龄妇女最常见的内分泌疾病。 其发病机制复杂,包含生殖,内分泌,代谢和心理等各方面因素,因此多囊卵巢综合征的病因仍然未知。多囊卵巢综合征女性出现心血管疾病、骨质疏松症和癌症的风险较高,严重威胁女性的健康和生存质量。本文对改善和治疗多囊卵巢综合征常见的药物作用通路及靶点进行介绍,以便发现更好的治疗药物,改善多囊卵巢综合征患者的生活质量。
