Objective:Advanced glycation end-products (AGEs) exert inflammatory and oxidative stress insults to produce diabetic nephropathy mainly through the receptor for AGEs (RAGE).This study aimed to assess the effect of atorvastatin on diabetic nephropathy via soluble RAGE (sRAGE) and RAGE expressions in the rat ***:Thirty-two male Sprague-Dawley rats were divided into four groups based on the presence or absence of streptozotocin-induced diabetes with or without atorvastatin treatment (10 mg/kg for 24 weeks).Serum sRAGE and glycated albumin (GA) levels were measured with enzyme-linked immunosorbent assay (ELISA) and improved bromocresol purple *** AGEs,RAGE,endogenous secretory RAGE (esRAGE),and sRAGE were determined with reverse transcription-polymerase chain reaction (RT-PCR) and Western ***:Mesangial expansion and microalbuminuria were aggravated in diabetic rats,and improved with atorvastatin *** sRAGE levels were lower in diabetic than in normal *** atorvastatin treatment,serum and renal sRAGE levels were up-regulated,while renal RAGE expression was decreased in diabetic rats,associated with a reduction in accumulation of AGEs,though renal esRAGE mRNA expression was not significantly ***:Atorvastatin exerted a beneficial effect on diabetic nephropathy with reduced AGE accumulation,down-regulating RAGE expression and up-regulating sRAGE in the kidney.

Clinical and angiographic features associated with coronary collateralization in stable angina patients with chronic total occlusion

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2013年第8期14卷 705-712页

作者： Zhen SUN Ying SHEN Lin LU Rui-yan ZHANG Li-jin PU Qi ZHANG Zheng-kun YANG Jian HU qiu-jing chen Wei-feng SHEN Department of Cardiology Shanghai Ruijin Hospital Institute of Cardiovascular Diseases Shanghai Jiao Tong University School of Medicine

Objective： Coronary collateral circulation is an alternative source of blood supply to myocardium in the presence of advanced coronary artery disease. We sought to determine which clinical and angiographic variables are associated with collateral development in patients with stable angina and chronic total coronary occlusion. Methods： Demographic variables, biochemical measurements, and angiographic findings were collected from 478 patients with stable angina and chronic total coronary occlusion. The presence and extent of collaterals supplying the distal aspect of a total coronary occlusion from the contra-lateral vessel were graded from 0 to 3 according to the Rentrop scoring system. Results： Low （Rentrop score of 0 or 1） and high （Rentrop score of 2 or 3） coronary collateralizations were detected in 186 and 292 patients, respectively. Despite similar age, cigarette smoking, and medical treatment, patients with low collateralization were female in a higher proportion and less hypertensive, and had higher rates of type 2 diabetes and dyslipidemia than those with high coUateralization （for all comparisons, P〈0.05）. In addition, patients with low collateralization exhibited more single-vessel disease, less right coronary artery occlusion, more impaired renal function, and higher serum levels of high-sensitivity C-reactive protein （hsCRP） compared with those with high col- lateralization. Multivariate analysis revealed that age of 〉65 years, female gender, diabetes, no history of hypertension dyslipidemia, moderate to severe renal dysfunction, single-vessel disease, and elevated hsCRP levels were inde- pendently associated with low coronary collateralization. Conclusions： Coronary collateralization was reduced in almost 40% of stable angina patients with chronic total occlusion, which was related to clinical and angiographic factors. The impact of coronary collateralization on outcomes after revascularization needs further investigation.

Role of Livestock Sector in the Socio-Economic Uplift of the Rural Pakistan

Journal of Agricultural Science and Technology(A) 2012年第10期2卷 1127-1133页

作者： Tunio Muhammad Tarique Shuming Yang Mohsina Zubair jing qiu Gang chen Ailiang chen Institute of Quality Standard and Testing Technology for Agro Products Chinese Academy of Agricultural Sciences Key Lab of Agri-food Safety and Quality Ministry of Agriculture Beijing 100081 China

Livestock sector occupies a very crucial position in the economy of Pakistan. The sector is equally important in irrigation as well as in arid/rain fed areas. Based on the valid reasons and available data, some scientists believe that livestock can strengthen and boost-up the economy of the rain fed/arid lands like Pothowar plateau where other enterprises like crops do not flourish and witness success due to drought and uncertain weather conditions. In this article, an attempt has been made to establish the role of livestock rearing in both the high and low potential areas. Their role in the overall economy of the country has been highlighted. Also many constraints in livestock business have been identified. The livestock sector in Pakistan has tremendous potential for growth. Therefore, a workable strategy for the promotion of the livestock has been outlined to uplift the rural economy and improve the socio-economic conditions of the rural dweller of the country.

Atherosclerosis is an inflammatory process due to oxidized low-density lipoprotein (oxLDL) accumulation in macrophages. We investigated the involvement of microRNAs in oxLDL accumulation and inflammatory response in macrophages. The expression of miR-146a decreases under oxLDL stimulation. MiR-146a significantly reduces intracellular LDL cholesterol content and secretion of interleukin 6,

The central nervous system, information integration center of the body, is mainly composed of neurons and glial cells. The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes and microglia belong to the glial cell family, which is the main source of cytokines and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeostasis. These channels are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peristalsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels and calcium channels, are closely related to various neurological disorders, including Alzheimer's disease, Parkinson's disease, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells and their involvement in neurological disorders such as Parkinson's disease, Alzheimer's disease, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells and could be u
