Objective To investigate the characteristic of type 2 diabetes (T2DM) patients with coronary heart disease (CHD),and provide methods for prevention and treatment for patients who suffered from CHD.Methods The hospitalized patients were divided into three groups.The treatment group contains 46 cases who were T2D with CHD;The control group Ⅰ contains 30 cases who were T2DM without CHD;The control group Ⅱ contains 50 cases who were CHD without T2DM.Their ordinary circumstances were compared;the blood sugar,BP,TC,TG,HDL,LDL,HbA1c,C-P,Ins were measured.Insulin sensitive index(ISI) was calculated.Results Three groups had obvious statistical differences in BP,TC,LDL-C,ISI,HbA1 c.Diabetic patients with CHD have more common with three lesions.Conclusion In the clinical job,the composite observation should be strengthened and treatment because the factors of atherosclerosis in T2DM patients were numerous and complex.

In order to examine the feasibility of cytokine fusion gene transfer into tumor cells, a retroviral vector (pLXSN) for human interleukin 6/interleukin 2 (IL6/IL2) fusion gene was constructed by using PCR and ligating the 2 genes with a synthesized flexible linker. The IL6/IL2 fused gene was introduced into B16 melanoma cell line mediated by retrovirus and the changes of adhesive and metastatic ability of fused gene-modified cells were detected. The B16-IL6/ IL2 cells showed efficient expression of both cytokines and decreased binding affinity with extracellular matrix (Laminin and Matrigel), accompanying with decreased experimental metastatic potentials. These data suggest that the mechanism involving the decreased metastases may relate with the changes of biological characteristics and immune stimulating activity of gene-modified cells.

Third-generation aromatase inhibitors (AIs) have been considered as standard adjuvant endocrine therapy for hor-mone-responsive breast cancer in postmenopausal women. Aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) are prevalent among patients undergoing AI therapy;these symptoms result in reduced quality of life and poor dependence to AI treatment. The mechanisms mediating AIMSS and the effective management of AIMSS have not been extensively investigated. This article re-views the incidence, clinical characteristics, possible mechanisms, and treatment of AIMSS.

Clinical data were retrospectively analyzed in 20 cases with Hashimoto's thyroiditis complicated with subacute thyroiditis from February 2009 to April 2013.85％ of the patients showed elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP).Thyroid peroxidase antibody (TPOAb) was found in 95 ％ of the patients,while thyroid globulin antibody (TgAb) in 100％.Uptakes of radioactive iodine were lowered.Symptoms such as fever or pain were ameliorated quickly after treatment with glucocorticoids or non-steroidal anti-inflammatory drugs.

Aim To investigate the cardioprotective effects and the possible mechanism of trimetazidine in the risky areas during late reperfusion after acute myocardial infarction in canine.Methods Twenty-four adult dogs were randomized into three groups:sham operation group(n=8),late reperfusion group(LR,n=8),late reperfusion after trimetazidine treatment group(LR+TMZ,n=8).Physiological saline was orally given in the sham operation group and LR group and trimetazidine(2 mg?kg-1?d-1) in the LR+TMZ group for fourteen days.After that later,all chests were opened and coronary areteries were exposed.Exceptly shame operation group,the late reperfusion of acute myocardial infarction model was made by ligating the coronary for 10 h,followed by reperfusion of 10 h.Apoptotic index were detected by TUNEL.The Bcl-2,Bax,Cytochrome C and apoptosis-inducing factor(AIF) proteins were detected by immunohistochemistry.Results Compared with those of LR group,myocardial apoptotic index and the expression of Bax,Cytochrome C and AIF proteins in LR+TMZ decreased significantly(all P

Objective To confirm the protective effect of berberine (BBR) on cold ischemia reperfusion (I/R)-induced liver injury and to show whether the hepatic protection conferred by BBR involves the activation of phosphatidylinositol 3 kinase (PI3K) / protein kinase B (Akt)/mammalian target of rapamycin(mTOR) signal pathway.Method Adult male Sprague-Dawley rats were assigned randomly to four groups:BBR group (BBR was intragastrically administered at a dose of 100 mg·kg-1 · d-1 2 weeks before hepatic cold I/R treatment),dimethyl sulfoxide (DMSO) group (BBR was replaced by DMSO,and others were the same as BBR group),I/R group (BBR was replaced by normal saline,and others were the same as BBR group) and sham group (normal saline was administered 2 weeks before opening and closing abdomen treatment).Then the rats were sacrificed at 3,6,and 24 h after reperfusion.The liver function,oxidative stress level,apoptosis rate,and the expression of PI3K/Akt/mTOR related pathway proteins were assayed.Result As compared with sham group,the I/R-induced liver tissue displayed severe lobular distortion with widespread necrosis,high level of oxidative stress and apoptosis rate.As compared with I/R group,BBR dramatically attenuated the histopathologic damage,restored the liver function and decreased the oxidative stress level.Simultaneously,BBR significantly ameliorated the apoptosis by decreasing the apoptosis rate,increasing the Bcl-2/Bax ratio and inhibiting caspase-3 activity in rats subjected to hepatic I/R.The expression of p-Akt was effectively upregulated with the inhibited expression of p-mTOR.Conclusion Our result provides robust in vivo evidence that BBR can prevent I/R-induced oxidative stress and apoptosis.The mechanisms involved can be attributed to the activation of P]3K/Akt/mTOR signal pathway.

As the basis of the health management of the elderly, weight management should receive attention from medical practitioners.However, there is an ongoing debate on the ideal range of body mass index for elderly in China.This article aimed to find the suitable body mass index for Chinese old people by reviewing the literature regarding the body mass and obesity of the elderly.Lots of evidence show that overweight and mild obesity appear to be the optimal weight status for the elderly.

Objective To study the effect of Coxsackie virus B3 (CVB3) infection on islet cells in vitro, and to explore the mechanism of islet cells caused by CVB3. Methods Bone marrow mesenchymal stem cells( BMSCs) were separated from the bone marrow and cultured. Then they were induced to differentiate into islet-like cells using nicotinamide and mercaptoethanol. Differentiated cells were detected by morphology , special staining and RT-PCR. Observe CVB3 infection on islet cells under inverse microscope and detect the specific gene fragment by RT-PCR. Results BMSCs showed half suspended shape and gathered to form a cluster after induction. Cells became red brown by dithizone specific staining. RT-PCR also proved the existence of mRNA expressing insulin. Infected islet cells appeared typical pathological changes like shrinks, refraction decreases. RT-PCR detected the desired specific gene fragment of 299 bp in infected islet cells. Conclusion CVB3 can directly injury islet cells, and damage the function of islet cells of secreting insulin.

Objective To evaluate the role of silent information regulator fac tor 2-related enzyme 1 (SIRT1)/Forkhead Box O3 (FoxO3a) signaling pathway in berberine pretreatment-induced reduction of hypoxia/reoxygenation (H/R)-caused injury to hepatic parenchymnal cells.Methods Hepatic parenchymal cells obtained from AML12 mice were cultured and seeded in 6-well plates (2 ml/well) and in 96-well plates (200 μl/well) at the density of l×l06 cells/ml.The cells were divided into 4 groups (n=36 each)using a randomn number table:control group (group C),group H/R,berberine pretreatment group (group BP) and SIRT1-siRNA group (group SS).The cells were cultured in normal culture atmosphere (5％ CO2-21％ O2-74％ N2) in group C.In H/R,BP and SS groups,the cells were exposed to hypoxic air (5％ CO2-1％ O2-94％ N2) for 12 h,followed by 6 h reoxygenation in normal culture atmosphere (5％ CO2-21％ O2-74％ N2).In group SS,small interference RNA targeting SIRT1 (SIRT1-siRNA) was added to the culture medium at 24 h prior to hypoxia.Berberine (final concentration 5 μmol/L) was added at 2 h prior to hypoxia in BP and SS groups.At the end of reoxygenation,the cell viability was measured by methyl thiazolyl tetrazolium assay,the malondialdehyde (MDA) content and superoxide dismutase (SOD) activity were determined using enzyme-linked immunosorbent assay,cell apoptosis was detected by flow cytometry,the expression of SIRT1 and FoxO3α was detected by Western blot,and the acetylation of FoxO3α was measnred by using immunoprecipitation.Apoptotic rate was calculated.Results Compared with group C,the cell viability was significantly decreased,the MDA content was increased,the SOD activity was decreased,apoptotic rate was increased,the expression of SIRT1 and ratio of FoxO3α expression in nucleus/in cytoplasma were increased,and the acetylation of FoxO3α in the nucleus was increased in H/ R,BP and SS groups (P＜ 0.05).Compared with group H/R,the cell viability was significantly increased,the MDA content was decreased,the SOD activity was increased,apoptotic rate was decreased,the expression of SIRT1 and ratio of FoxO3α expression in nucleus/in cytoplasma were increased,and the acetylation of FoxO3α in the nucleus was increased in group BP (P＜0.05).Compared with group BP,the cell viability was significantly decreased,the MDA content was increased,the SOD activity was decreased,apoptotic rate was increased,the expression of SIRT1 and ratio of FoxO3α expression in nucleus/in cytoplasma were decreased,and the acetylation of FoxO3α in the nucleus was decreased in group SS (P＜O.05).Conclusion The mechanism by which berberine pretreatment attenuates H/R-caused injury to hepatic parenchymal cells is related to promotion of SIRT1 expression in cells and inhibition of FoxO3α acetylation in the nucleus.

Objective To assess the diagnostic performance of CT for detecting anastomotic leak after esophagectomy.Methods A total of 50 patients who underwent both CT and fluoroscopy after esophagectomy in our hospital from September 2013 to December 2015 were enrolled in this study.The fluoroscopy features and CT findings were analyzed retrospectively.Results The sensitivity,specificity,positive and negative predictive values were 100%,86.67%,83.33%,100%,respectively,for CT,and 85%,100%,100%,90.91%,respectively,for fluoroscopy.The differences in CT features,including leak of contrast,wall discontinuity and air-fluid collection in the mediastinum were statistically significant between leak and no leak(P=0.000,P=0.000,P=0.005,retrospectively),while no statistically significant in air collection in the mediastinum,hydropneumothorax,pleural effusion and pneumatosis.The maximum diameter of air collection in leak was(1.54±0.97)cm,while the maximum diameter of air collection in no leak was (0.56±0.20)cm,the difference in the maximum diameter of air collection between leak and no leak was statistically significant(P=0.007).Conclusion CT is more sensitive but less specific than fluoroscopy for detecting anastomotic leak.CT can be a better choice for the patients who can not tolerate the fluoroscopy or the fluoroscopy results is negative but anastomotic leak is still suspected.
