Diabetic cardiomyopathy(DCM) is a disease independently related with coronary artery atherosclerotic heart disease, hypertensive heart disease, valvular heart disease, congenital heart disease and other heart diseases that are uniquely associated with diabetes mellitus, and the pathological manifestations of DCM are mainly myocardial hypertrophy, interstitial fibrosis, necrosis and apoptosis.Endoplasmic reticulum is the central location of many important cellular functions, and endoplasmic reticulum swelling and functional disorder in diabetic cardiomyocytes, high blood sugar can cause endoplasmic reticulum stress, suggesting that endoplasmic reticulum stress(ERS) may be involved in the pathogenesis of diabetic cardiomyopathy and development.Based on this, this paper summarizes the progress of ERS in diabetic cardiomyopathy from the pathogenesis of diabetic cardiomyopathy, unfolding protein reaction and the related role of ERS in DCM.

Objective Based on the published articles,this paper aims to study the pattern and probability of lymph nodes metastasis in nasopharyngeal carcinoma (NPC) and establish a radiotherapy standard for selecting and delineation of clinical target volume of neck lymphatics for NPC patients with N0 or N1.Methods Clinical trials about NPC by MRI as the main or only diagnostic imaging way were collected and extracted from database,such as WanFang,CBM,PubMed,Cochrane Library.Statistical analyses were performed using Stata software,version 12.0.Results Twenty-one clinical trials from 963 original articles were included in this analysis.The most commonly involved regions included retropharyngeal (67％) and level Ⅱ lymph nodes (71％).The overall probability of levels Ⅲ,Ⅳ and Ⅴnodal involvement were 37％,14％ and 21％,respectively.Low-risk node groups included levels ⅠA,ⅠB,Ⅵ nodes,and the rates of lymph node metastasis were 0,2％,2％ and 1％,respectively.Nodal metastases followed an orderly pattern of top-down,and the probability of skip metastasis between levels varied between 0.5％ ～7.9％.Conclusion Lymph node metastasis in NPC follows a predictable and orderly pattern.The rarity of metastasis in certain nodal groups andskip metastasis suggest that reduced treatment volume is feasible in conformal radiotherapy for NPC patients with No or N1.

Objective With the emerging omnipresence of arthroscopy, the plica syndrome has achieved a clinical recogni-tion as a pathological entity .This study is to investigate the clinical diagnosis and treatment of the medial plica syndrome of the knee . Methods We retrospectively analyzed 198 cases of medial plica syndrome, internal semilunar cartilage and chondromalacia patellae in the knee joints treated in our department from January 2008 to December 2011 .All the patients received physical and MRI examina-tions before admission and underwent plicaectomy, their knee function evaluated according to their Lysholm scores pre-and post-opera-tively. Results The diseased plica synovialis was completely excised in 46 cases diagnosed as simple medial plica syndrome by ar-throscopy.Forty-four of the patients were followed up for 6 to 32 (mean 26) months, and the excellence rate of treatment result was 95.5%. Conclusion Medial plica syndrome of the knee constitutes a larger proportion of knee disorders, for which arthroscopy re-mains the best diagnostic option and total excision of the diseased plica synovialis is an effective treatment .

Aim To explore the role of nicotinamide adenine dinucleotide phosphate ( NADPH ) oxidase in high fat-induced injury in MIN6 isletβ cells. Methods MIN6 islet β cells were exposed to different concen-trations of palmitic acid ( 0. 1 , 0. 3 , 0. 5 , 0. 8 mmol · L-1 ) for 48 h and different time points of 0. 5 mmol· L-1 palmitic acid(24,48,72,96 h). Cell viability was measured by MTT, the protein expression of NADPH oxidase subunits such as p22 phox , p47 phox , p67 phox and gp91 phox and apoptosis related proteins such as Bcl-2 and Bax were determined by Western blot. Results MIN6 islet cells exposed to palmitic acid at 0. 5 mmol ·L-1 for 48 h showed a decrease in their viability and an increase in the expression of NADPH oxidase sub-units(p22phox、p47phox、p67phox and gp91phox) and Bax(P<0. 05 ) , while Bcl-2 expression was significantly re-duced. the pretreat with NADPH oxidase inhibitor di-phenyliodonium( DPI,10 μmol · L-1 ) significantly in-hibited high fat-induced Bcl-2 and Bax expression( P<0. 05 ) . Conclusion Activated NADPH oxidase might play an important role in the treatment of high fat-in-duced injury in MIN6 islet cells.

Thirty male weanling WAK strain rats were divided rondomly into 6 groups. All of the diets were pure synthetics according to AOAC. The 1st, 2nd and 3rd group were given diets containing 6, 15 and 24 ppm of zinc respectively, and 10% protein for all three groups, on the other hand, the 4th, 5th and 6th group were given diets containing 5% 10% and 20% of protein respectively, and 15 ppm of zinc.After feeding in stainless steel cage singly for 50 days rats were given intubately solution of 65Zn containing 1.5 ?Ci per 100g of body weight. Then the faeces and urine of rats were collected on 5 consecutive days, and the zinc absorption and retention of all of the tested rats were determined with method of 65Zn as tracer. The results indicated that. (1) The zinc absorption and retention of rats fed on the lowest zinc level were increased significantly. (2) The zinc absorption and retention of rats fed the lowest protein level were decreased significantly, and were improved clearly by increasing protein intake level. (3) The urine excretion of zinc is very low and can not be used as an index in zinc metabolism research. The methodology for determining zinc absorption and retention in organism with method of 65Zn and total zinc is discussed.

Transcranial Doppler can be used for diagnosing,monitoring,identifying the site of arterial occlusion,selecting appropriate cases for thrombolysis,and monitoring arterial recanalization during intravenous thrombolysis,and intra-arterial and intravenous thrombolysis with recombinant tissue plasminogen activator,The continuous monitoring of low frequency transcranial ultrasound has the effect of assisted thrombolysis;however,there are still controversies on the frequencies used in clinical practice.Transcranial Doppler assisted with microbubble contrast agent may further enhance the effect of thrombolysis.

AIM: To study the effects of norepinephrine preconditioning(NE-P) and ischemic preconditioning (IP)on apoptosis and Bcl-2, Bax expression in rat myocardial cells in myocardial ischemic reperfusion (I/R). METHODS: The model of rat ischemic-reperfusion was used to conduct NE-preconditioning. Apoptotic myocytes were detected with TUNEL. Bcl-2, Bax expression were detected with immunohistochemistry. RESULTS: The rate of apoptosis cells in I/R group was higher, the rate of apoptosis cells in NE-P group and IP was lower significantly than that in I/R group( P0.05). CONCLUSION: NE-P reduced myocyte apoptosis by I/R in rats; The expression of Bcl-2 ,Bax genes played an important role in myocardial apoptosis.
