Objective To evaluate the myocardial microvascular obstruction induced by occlusion of single coronary artery (OSCA) and stenosis of multi-coronary arteries (SMCA) using first-pass perfusion cardiac MRI. Methods We studied 33 patients who had acute myocardial infarct and received emergency coronary angiography and angioplasty. Coronary angiogram confirmed that 15 patients had complete occlusion of the single coronary artery and 18 patients had multi-coronary artery stenosis without occlusion. Cardiac MRI (CMRI) exam was performed at 6-12 weeks after diagnosis. Results CMRI demonstrated that 15 patients had first-pass perfusion defect in the endomyocardium. The signal intensity (SI) of the perfusion defect was significant lower than that in the normal myocardium. The maximal slope of SI showed that the there were 11 patients with occlusion of the single coronary artery and 4 patients with stenosis of multi-coronary arteries. Conclusion CMRI can show the microvascular obstruction limited in the region of endomyocardium. CMRI suggests that the occlusion of the single coronary artery may induce more severe myocardial microvascular obstruction than the stenosis of multiple coronary arteries.

Objective: This study aims to investigate the clinical effect of bronchoscopic interventional cryotherapy in the treatment of bronchial tuberculosis (BTB). Methods:158 patients admitted into our hospital from October 2012 to October 2015 were randomly divided into observation group (n=80) and control group (n=78). The control group was treated with standardized systemic chemotherapy, and the observation was treated by bronchoscopic interventional cryotherapy based on the control group in order to compare the negative rate of sputum bacteria, clinical efficacy and adverse reactions. Results: After treatment, the turn rate of the observation group was 98.75%, significantly higher than that of the control group (89.74%) (x2=5.964, P<0.05). Clinical effective rate was 97.50% in the observation group, significantly higher than the control group (84.62%) (x2=8.119, P<0.05). The adverse reactions of the observationt group were 5.00% and they were 12.82%in the control group. There was no statistical significance between the two groups (x2=2.236, P>0.05). Conclusion:It has obvious clinical curative effect of bronchoscopic interventional cryotherapy in the treatment of BTB. With simple operation, it has a higher negative rate of sputum bacteria and lower incidence of adverse reactions. It also can effectively improve the pulmonary function and protect lung tissue, which is worth popularizing in clinical application.

Objective:To evaluate the predictive value of 3 methods, namely plasma paraquat concentration, severity index of paraquat poisoning (SIPP), and acute physiology and chronic health evaluation (APACHE II) in severity evaluation and prognosis of acute paraquat poisoning. Methods:A total of 73 acute paraquat poisoning patients with oral administration were collected. Paraquat concentration in the plasma and other parameters on admission for SIPP and APACHE II were taken from medical records. According to the clinical outcome in the hospital or 7 days atfer the discharge, discrimination and calibration test were performed to evaluate the prognosis of the 3 methods. Results:Discrimination of the 3 methods was greater than 0.8, and the area under the receiver operator curve for SIPP (0.938) was greater than paraquat concentration in the plasma (0.857) and APACHE II (0.801) with statistical signiifcance (z=2.429, 2.021;P=0.015, 0.043). Difference in plasma paraquat concentration (0.857) and APACHE II (0.801) had no statistical signiifcance (z=0.755, P=0.450). Hosmer-Lemeshow good fit test suggested better calibration value with statistical signiifcance for the 3 methods (P>0.05). Conclusion:hTe 3 methods are valid in the severity evaluation and prognosis of acute paraquat poisoning. SIPP is the most preferred method, followed by paraquat concentration on admission. When there is no facility to measure paraqut concentration, APACHE II can be used as a reference for the death risk in acute paraquat poisoning.

Induced pluripotent stem cell ( iPS cell ) , similar to embryonic stem cell, can be repro-grammed to the pluripotent state by ectopic expression of specific transcription factors. The iPS cells have pluri-potency and can be induced into neuron cells,which represent a promising cellular tool to study human neurode-velopmental disease,drug screening,diagnosis and personalized treatment. This article reviews the latest progress on iPS cell and its applications in neural developmental disease.

Objective To study the expression of RASSF1A gene in gastric cancer tissues and cell lines and to investigate its clinical roles. Methods Immunohistochemistry was employed to detect the expression of RASSF1A gene in 39 cases of human gastric cancer tissues and 18 cases of normal human gastric tissues, and RT-PCR was used to examine the expression of RASSF1A mRNA in 4 gastric cancer cell lines, normal gastric cell lines GES-1 and positive control Hela cells. Correlations between expression of RASSF1A gene and clinicopathological characteristics of gastric cancer were also analyzed. Results All the normal gastric tissues (18 cases) were stained with anti-RASSF1A antibody, and significantly lower expression of RASSF1A was found in the 39 cases of gastric cancer tissues (P

Objective To analyze the drug resistance of Escherichia coli isolated from urinary tract infection and risk factors of quinolone resistance strains.Methods A total of 705 cases (strains) with Escherichia coli drug resistance isolated from urine specimens were divided into quinolone sensitive group [474 cases(strains)] and quinolone resistance group [231 cases(strains)].The risk factors of the quinolone resistance strains were analyzed.Results The sensitivity rate of amoxicillin/clavulanic acid,cefalotin,ceftazidime,aztreonam,piperacillin,amikacin,compound sulfamethoxazole,ciprofloxacin,gentamicin,levofloxacin,cefepime in quinolone resistance group was higher than that in quinolone sensitive group [50.2％(238/474) vs.78.8％(182/231),11.6％(55/474) vs.48.5％(112/231),17.9％(85/474) vs.63.2％(146/231),15.0％(71/474) vs.57.6％(133/231),3.2％(15/474) vs.27.7％(64/231),80.8％(383/474)vs.93.1％(215/231),16.0％(76/474) vs.49.8％(115/231),0 vs.100.0％(231/231),32.5％ (154/474)vs.70.6％ (163/231),3.8％ (18/474) vs.98.7％ (228/231),18.6％ (88/474) vs.63.2％ (146/231),P ＜0.05].Logistic regression analysis showed history of using the third generation cephalosporins and quinolones,urinary drainage and bacterium producing extra-broad spectrum beta-lactamase was independent risk factor for quinolone resistance Escherichia coli (P ＜ 0.05).Conclusions The epidemic of quinolone resistance Escherichia coli isolated from urine specimens is extremely serious.The quinolone resistance is strong,and infection patients have a high medical cost and average length of stay.The quinolone resistance Escherichia coli infection has multiple independent risk factors.To strengthen the control of the independent risk factors can effectively prevent quinolone resistance strains infection spread.

ObjectiveTo investigate the effects of nicotine on the expression of Th1/Th2 cytokines and transcription factor T-bet/GATA-3 in cultured CD4+ T of rat sensitized by ovalbumin.Methods Two weeks after immunization by ovalbumin,splenic CD4+ T cells of Wistar rat were purified using CD4+T cell enrichment kit.Purified CD4+ T cells of rat were cultured and divided into 4 groups:a control group,1 μg/ml nicotine stimulated group,10 μg/ml nicotine stimulated group,100 μg/ml nicotine stimulated group.These cells,in their groups,were stimulated with or without nicotine and were all challenged simultaneously with OVA.Supernatants and cell pellets were harvested after being stimulated for 24 h.The concentration of IFN-γ and IL-4 in supernatants were measured by enzyme-linked immunosorbent assay (ELISA).Real-time PCR was used to determine the mRNA expression of T-bet and GATA-3 in CD4+T cells.Results ( 1 ) IFN-γproduction was significantly decreased in all nicotine treated groups [ ( 113.78±6.06) ng/L,(70.31±7.26) ng/L,(20.00±2.14) ng/L] compared with the control group[ (142.30± 5.89) ng/L],and the level of IL-4 was significantly increased in all nicotine treated groups [ (69.49±3.91) ng/L,(93.63±4.56) ng/L,(50.97±3.07) ng/L] compared with the control group[ (36.91±3.24) ng/L].(2) Expression of T-bet mRNA in all nicotine treated groups(0.73±0.03,0.57±0.04,0.31 ±0.00) was lower than that in the control group(0.98±0.09),but expression of GATA-3 mRNA in all nicotine treated groups (4.31±0.26,5.16±0.23,1.56±0.14) was significantly higher than that in the control group(1.00±0.07).Conclusion Nicotine may play a key role in the development of Th2-type allergic inflammation in asthma by promoting over-expression of GATA-3 mRNA and downregulating the expression of T-bet mRNA.
