恶性肿瘤发病率及死亡率在我国均很高,且就诊时大多已为晚期。因此加强肿瘤病因、病机及诊疗的研究,提高早期诊断率及疗效已成为临床工作的重点;而近年来大量研究表明血液中IGFs水平升高,与乳腺癌、肺癌、肝癌、胃癌、结肠癌等恶性肿瘤发病呈明显正相关,IGFs的信号通路研究有望成为它在肿瘤早期诊断、分子靶向治疗方面提供有力的帮助。 相似文献

中医药诊治类风湿关节炎的研究现状 总被引:2,自引:0,他引:2
类风湿关节炎(Rheumatoid Arthritis,RA)是一种以慢性、对称性、侵蚀性关节炎损害为主要表现的全身性自身免疫性疾病。中医药治疗RA具有较好的临床疗效。近年RA的病因病机研究以风寒湿三气夹杂理论为基础,多从痰瘀互结、热毒瘀结的角度或者脏腑气血虚损方面进行。治疗上除了使用经典专方外,侧重于中药单体或提取物运用的研究,并提倡综合治疗。虽然中医药在诊治类风湿关节炎取得了很大的进展,但在研究和治疗的系统化及规范化方面尚需进一步的加强。 相似文献

近年来,据不完全统计,由病原微生物引起的所有呼吸道疾病中,由病毒导致的急性呼吸道感染约占80%,是目前世界范围内发病率最高的疾病。呼吸道病毒,如严重急性呼吸系统综合征冠状病毒 (SARS-CoV)、SARS-CoV-2,甲型流感病毒和呼吸道合胞病毒等,对社会公共卫生安全构成较大威胁,目前,还没有开发出特效药。由于中药具有多组分多靶点的协同作用,在呼吸道病毒疾病的预防、治疗康复和保健方面具有独特的优势,近年来,许多临床医生和研究人员从不同层面对中药治疗呼吸道病毒疾病进行了一系列研究和探索,对中医药的临床疗效和治疗机制有了更清晰的认识。本文通过综述中医药治疗呼吸道病毒疾病的临床疗效研究和作用机制,为中医药更好治疗呼吸道病毒疾病提供有力的证据,以期推动中医药的发展及其在呼吸道病毒疾病方面的潜在应用。 相似文献

BACKGROUND:There is a certain association between stem cells, microenvironment and methods for promoting blood circulation and removing stasis.
OBJECTIVE:To propose a perspective of “kidney properties” of promoting blood circulation and removing stasis by elaborating the correlation and interactions of stem cells and microenvironment with methods for promoting blood circulation and removing stasis.
METHODS:A computer-based search of Chinese Journal Full-text Database, Wanfang and PubMed was performed for articles published form 2009 to 2015 addressing improving stem cell proliferation and differentiation by promoting blood circulation and removing stasis as well as microenvironments. The keywords were “bone mesenchymal stem cells, transformation, differentiation, blood-activation and stasis-resolved method, microenvironment” in Chinese and English, respectively. Finally, 32 literatures were reviewed.
RESULTS AND CONCLUSION:Stem cells homing to the damaged tissue trigger an “environment- dependent differentiation”, that is, stem cells can differentiate into myocardial cells, vascular endothelial cells and other injured tissues and cells under local special microenvironments. Microenvironment as an assembly for integrating dynamic, microscopic changes as well as development of a variety of indices is of great importance for stem cell survival, proliferation and differentiation. Recipes for promoting blood circulation and removing stasis are involved to regulate multi-steps and multi-targets during stem cell homing. Theoretically, this review attempts to investigate correlation among stem cells, microenvironment and methods for promoting blood circulation and removing stasis in association with previous preclinical and clinical findings. Here, we further refine the view of “kidney properties” of promoting blood circulation and removing stasis and clarify that stem cells as the material basis of “kidney properties” of promoting blood circulation and removing stasis is the main executor for promoting blood circulation and removing stasis. This paper is of a certain value for fully revealing the scientific connotation of the theory of promoting blood circulation and removing stasis. 相似文献

Objectives: A significant proportion of discharged COVID-19 patients still have some symptoms. Traditional Chinese medicine (TCM) has played an important role in the treatment of COVID-19, but whether it is helpful for discharged patients is still unknown. The aim of this study was to retrospectively analyze the impacts of TCM treatment on the convalescents of COVID-19.Methods: A total of 372 COVID-19 convalescents from February 21 to May 3 in Shenzhen, China were retrospectively analyzed, 291 of them accepted clinically examined at least once and 191 convalescents accepted TCM.Results: After retrospective analysis of the clinical data of convalescents accepted TCM treatment or not, we found that the white blood cell count, as well as serum interleukin-6 and procalcitonin decreased in TCM group. Serum γ-glutamyl transpeptidase was significantly decreased, while prealbumin and albumin increased in TCM group. Red blood cell, hemoglobin, and platelet count increased in TCM group. The mechanisms of TCM treatment might be the overall regulations, including balanced immune response, improved hematopoiesis and coagulation systems, enhanced functions of liver and heart, increased nutrient intake and lipid metabolism.Conclusions: This study suggested that TCM treatment would be beneficial for discharged COVID-19 patients. However, long-term medical observation and further study with randomized trial should be done to confirm this result. Besides, the potential molecular mechanisms of TCM treatment should be further revealed. 相似文献

The development of genetic models for research on hypertension and stroke, spontaneously hypertensive rats (SHR) and stroke-prone SHR (SHRSP), have contributed not only to the elucidation of the pathogenesis of hypertension-related cardiovascular diseases (CVD) but also to their prediction and prevention. Since both genetic and environmental factors are involved in the pathogenesis of hypertension and stroke in SHR and SHRSP, the detection of the genetic factors and the control of environmental factors have been proven to be useful as predictive and preventive measures against hypertension and related CVD. Early rise in blood pressure, sympathetic overre-sponsiveness, early development of cardiovascular hypertrophy, increased salt sensitivity and membrane abnormalities detected in vascular smooth muscle cells (VSMC) from SHR and SHRSP, which are related to the pathogenesis of hypertension, have been examined for their applicability to the prediction of hypertension in man. Pathogenic mechanisms of stroke in SHRSP have been studied by electron microscopy, and VSMC degeneration and necrosis were noted to start at the outer media of intracerebral arteries which were exposed to local hypoxia and hyponutrition due to limited diffusion through the blood brain barrier. Macrophages are involved in the process of arterionecrosis with fibrin deposition in SHRSP, and their involvement has also been proven immunohistochemically in human autopsy cases. Moreover, reduction of regional cerebral blood flow, hypoxic vulnerability of the brain detected by the NMR techinique and additional cellular abnormalities such as membrane fragility and accelerated lipid incorporation may possibly be applied to the prediction of stroke and atherosclerotic diseases in man. On the other hand, experimental control of cellular, neural and vascular mechanisms of hypertension and stroke in these animal models have been proven to be effective for the prevention of CVD not only pharmacologically but also non pharmacologically by dietary sodium reduction, and increased intake of potassium, calcium, protein and dietary fiber. The applicability of dietary control of hypertension and stroke to humans has been supported by our epidemiological studies in Japan as well as by the WHO coordinated international cooperative study on cardiovascular diseases and alimentary comparison (WHO CARDIAC study). These new experimental and epidemiological findings are extending new horizons in medicine, where the main medical activity should be focused on the prediction of diseases by detecting genetic disposition as well as on prevention by the control of environmental factors.

背景:多项研究表明脐血干细胞移植可以改善脑缺血后的神经功能缺损。
目的:总结脐血干细胞移植治疗脑卒中的研究进展及其作用机制。
方法:由第一作者应用计算机检索2001-01/2011-08 PubMed数据库及万方数据库有关脐血干细胞移植治疗缺血性脑卒中基础研究方面的文献。检索词“umbilical cord blood stem cells,focal cerebral ischemic,transplantation,脐血干细胞,局灶性脑缺血,移植”,共检索到文献50篇,最终纳入符合标准的文献30篇。
结果与结论:脐血干细胞具有自我更新和多向分化潜能,在适当的诱导下可分化为神经细胞。相关研究表明脐血干细胞能缩减脑卒中大鼠的脑梗死体积并改善行为学预后,其机制包括减轻炎症反应,增加营养因子的分泌,促进血管发生和神经纤维重塑等。虽然脐血干细胞在实验研究上取得了较大进展,但仍有许多问题有待解决,如何提高脐血的利用率,如何限制干细胞的过度增殖,整合到损伤部位的移植细胞是否能发挥功能等,待进一步探讨。 相似文献
