Objective To evaluate the irreversible ischemia injury in patients with acute coronary syndrome using Cardiac MRI. Methods We have studied 35 patients with acute coronary syndromes who received standard medical therapy. Coronary angiogram confirmed that all the patients had suffered from multi-coronary artery stenosis without total occlusion. Cardiac MRI (CMRI) examinations were performed 6-12 weeks after the coronary angiography and revascularization. IR-GRE was used in the CMRI protocal to detect myocardial delayed enhancement (viability). The definition of hyperenhancement was that the signal of the region was two times that of the remote myocardium. The hyper-enhanced volume was presented as a percentage of LV mass (%LV), i.e. The total number of hyperenhanced pixels divided by the total number of pixels of the LV myocardium and multiplied by 100. Results CMRI revealed that all the patients had hyperenhanced region, of whom 30 (85.7%) had non-transmural enhancement and only 5 (14.3%) had transmural enhancement. The average size of the enhancement of non-transmural was significantly smaller than that of transmural hyperenhancement (45.7?7.3%). Conclusion The CMRI can demonstrate that infarction has occurred in patients with multi-coronary arteries stenosis.

Objective To investigate the effects of hypoxia inducible factor-2?(HIF-2?) on the proliferation and invasion of hepatocellular carcinoma cell line SMMC-7721 under the anoxia condition.Methods Lipofectamine-mediated HIF-2? oligodeoxynucleotide(ODN) was transfected into SMMC-7721 cells and the expressions of HIF-2? mRNA and protein were detected to evaluate the transfection.The proliferative and adhesive activity was determined by methyl thiazolyl tetrazolium(MTT) method and the invasive activity was determined by a transwell cell culture chamber method.Results The expressions of HIF-2? mRNA and protein were inhibited significantly by HIF-2? antisense oligodeoxyribonucleotide(ASODN)(P0.05).Conclusion The blockage of HIF-2? expression inhibits the adhesive and invasive activity of SMMC-7721cells,and has no evident impact on their proliferation.

Objective To research the clinical efficacy of Sini decoction adjustment combined rabeprazole enteric capsules in treatment of gastroesophageal reflux cough and its effect on interleukin 8 (IL-8) and substance P (SP), the mast cell tryptase (MCT) levels.Methods 92 cases of gastroesophageal reflux cough were divided into control group and experimental group by drawing method , each had 46 cases.Control group were treated by rabeprazole enteric capsules, experimental group were treated with rabeprazole enteric capsules based on the control group.The curative effect, cough symptoms integral, IL-8, SP, MCT, gastric dynamic element (MOT) and the gastrin-releasing (GAS), pulmonary function and safety were compared between two groups.Results The total effective rate of experimental group(93.47%) was higher than the control group(76.08%), the difference was statistically significant (P<0.05).After treatment, the symptoms of experimental group(1.53 ±0.19) points was higher than the control groupthe difference was statistically significant(1.96 ±0.24)points,P<0.05.The IL-8, SP, MCT levels of experimental group were all lower than the control group ( P<0.05 ) .The MOT, GAS, and lung function of experimental group improved more significantly than the control group ( P <0.05 ) .The security between two groups has no significant difference .Conclusion The curative effect of Sini decoction adjustment combined Rabeprazole enteric capsules in treatment gastroesophageal reflux cough is obvious, can decrease IL-8, SP, MCT levels.

Objective To evaluate the efficacy and side effects of the combination of tocetaxel and cisplatin in the treatment of advanced non-small cell lung cancer (NSCLC). Methods Thirty patients were treated with the combination for two courses. Every three weeks, tocetaxel was administrated on day 1 in a dose of 75mg/m~2 and cisplatin in dose of 30mg/m~2 from day 1 to day 3. Results Complete remission was found in two patients, partial remission in fourteen patients, in seven patients there was no change, and in seven patients there was an advance of the disease. The overall remission rate was 53.3%. The main side effects were suppression of myelopoiesis, gastrointestinal disturbance, alopecia, myalgia and arthralgia. Conclusion The combination of tocetaxel and cisplatin is effective and well-tolerated in the treatment of NSCLC.

Objective To study on the changes of the IL-6、IL-8、TNF-? in the type 2 diabetes with insulin resistance and the relation of plasma glucose or insulin resistance and cytokines. Methods (1) To assay the serum level of cytokines in 90 cases with type 2 diabetes mellitus (T2DM) and 30 normal controls. (2)To measure the level of fasting plasma glucose (FPG),hemoglohin A_1c (HBA_1c),fasting insulin(FINS),fasting C-peptide (FCP).(3) To analysis the relation of the level of FPG,HBA_1c,FINS,FCP and cytokines. Results (1) The serum levels of cytokines in T2DM group were significantly increase than in control groups,IL-6 and TNF-? in T2DM group with insulin resistance were significantly increase than in T2DM group without insulin resistance (2) There was significantly positively correlated between insulin resistance and the increasing of cytokine levels. Conclusion There is an excess activation of cytokines in T2DM,which is significantly correlated with insulin resistance. Cytokines play the important role in the occurrence and development of T2DM and insulin resistance.

Objective By analyzing the clinical and pathological characteristics of small intestinal neoplasms of patients presenting at our hospital,this study was to improve our cognition of this disease and the prognosis.Methods We collected and reviewed the medical records of 121 patients suffering from small intestinal neoplasms,who underwent surgery at Ruijin hospital from January 2003 to June 2009.Diagnosis was confirmed by pathological examination,and patients were followed-up.Results Intestinal hemorrhage,anemia and abdominal pain were the three main symptoms for all patients.CT,and gastrointestinal endoscopy were valuable for the diagnosis of small intestine neoplasms.Compared with open surgery,laparoscopic procedures can shorten the operation time and the postoperative length of hospital stay.Conclusions Surgical procedure is the key treatment for patients with small intestinal neoplasms.Long term follow-up plays important role in the detection of other synchronous or metachronous gastrointestinal tumors and improves the prognosis.

Objective To study the changes of Na+K+-ATPase,Ca2+Mg2+-ATPase activities in erythrocyte membrane and blood viscosity in children with essential hypertension.Methods The activities of Na+K+-ATPase,Ca2+Mg2+-ATPase in erythrocyte membrane were determined by a colorimetric method.Blood viscosity was measured and analyzed with the statistic analysis SPSS 12.0 software in 50 children from Nov.2004 to Dec.2004 in the people's hospital of guizhou province and adolescents with essential hypertension.Thirty healthy children were collected as control group.Results The activities of Na+ K+-ATPase[(6.12?1.30)?molpi/(gHb?h)and(4.59?1.40)?molpi/(gHb?h)],Ca2+Mg2+-ATPase[(7.46?1.30)?molpi/(gHb?h)and(5.81?1.20)?molpi/(gHb?h)] were lower significantly in hypertension group than those in control group(Pa

Cancer is considered as one of the major diseases endangering human health in the world, it is urgent to find a safer and more efficient treatment for cancer therapy. Gene therapy with ribonucleic acid (RNA) drugs could regulate the expression of tumor related genes, and exhibit good anti-tumor therapeutic potential in preclinical and clinical trials. Based on the differences between tumor tissues and normal tissues in microenvironment signal characteristics such as pH, specific enzyme concentration or redox gradient, various microenvironment responsive nanocarriers had been studied and developed to deliver RNA drugs to tumor tissues and cells, improving the anti-tumor efficacy of RNA drugs and reducing toxic and side effects. This paper reviews the pathophysiological characteristics of tumor microenvironment and various strategies of tumor microenvironment responsive nanocarriers, in order to provide reference for the design of safe and efficient RNA drug delivery system for cancer therapy.
