Objective To compare the efficacy of transcatheter closure of patent ductus arteriosus by using Amplatzer occluder and a new home-made occluder.Methods Comparing the efficacy,complications and cost of 110 patients with home-made occluder and 96 patients treated with Amplatzer occluder.Results The case of complete closure:the home-made occluder group was 109(99.1%),the Amplatzer occluder group was 95(99.0%).The comparison of preoperatively clinical indexs,operative and exposure time,the rate of complete closure,hospital days and complication were not significantly different.The decrease of left ventricular diastolic and C/T have no significant difference.The total cost of the home-made occluder group was statistically lower than the Amplatzer occluder group.Conclusion Both groups have no significant difference in the efficacy and the rate of complication.The new home-made occluder is low cost and extensive applicative foreground in clinics.

Objective To analyze distribution and drug resistance of MRSA separated,to probe into a treat method for MRSA infection and offer scientific gist for reasonable use of clinical antibiotic. Methods 568 MRSA separated from clinic were measured and a drug sensitivity test was performed by means of Kirby-Bautr agar diffusion method. Results 370 individual plants were filtered, the rate of inspection was 65.1%. MRSA was 36.2 % among them,MRSCON was 77.5% ,the drug resistance of MRSA to quinolones(21% ～48% ) was below MRSCON(84 %～89 % ). The drug resistance of MRSA and MRSCON obviously excelled MSSA and MSSCON ( P＜0.05 ). VRS was undiscovered. Conclusion Severe infection caused by MRS should choose vancomycin resistant enterococci to cure at fist. Staphylococcus was one of primary pathogenic bacterium caused infection in hospital, MRS had multiple drug resistance and measure range about drug resistance should be extended, which would advance the cognition about the drug resistance of antibiotic and cut off the transmitted path, reduce the drug resistance of bacteria and the infection rate in hospital.

The course of functional laboratory science is the bridge between classroom and clinical practice.In functional laboratory science teaching,we should pay attention to features of nursing care,focus on training compassion,clinical awareness,collaboration ability,practical skills for nursing students and combine the reform of functional laboratory science teaching with cultivation of professional quality for nursing students.

Objective To study the protection of Kangnaoling capsule to free radical injury and influence on the expression of caspase-3 and Bcl-2 in neuron of VD rat. Methods VD rat model was duplicated. Using spectrophotometry to detect contents of SOD, MDA and NO, spectro-fluorimeter to detect the expression of caspase-3, spectrophotometric method to detect the expression of Bcl-2 after traditional Chinese medicine interference. Results Kangnaoling capsule can markedly reduce the contents of MDA, raise contents of SOD and NO, degrade the expression of caspase-3, enhance the expression of Bcl-2. Conclusions Kangnaoling capsule can markedly protect VD rat from free radical injury, which probably correlated with increasing expression of Bcl-2, decreasing expression of caspase-3.

Objective To investigate the distribution and drug resistance of pathogenic bacteria in hospital ICU patients with lower respiratory tract infection , and provide scientific reference for clinical rational drug use . Methods The strains were identified by VITEK -32 automatic bacterial identification instrument , the bacterial sensitivity was determined by K -B disk diffusion method , and the statistical analysis was performed by WHONET 5.4 software.Results The total isolated pathogenic bacteria of lower respiratory tract infection in ICU patients was 453 strains.332 strains of gram negative bacteria accounted for 73.3%,and the former three ones were Pseudomonas aeruginosa (115 strains,accounted for 25.4%),Klebsiella pneumonia (90 strains,accounted for 19.8%),Acineto-bacter baumannii (38 strains,accounted for 8.4%).102 strains of gram positive bacteria accounted for 22.5%,and the top three were Staphylococcus aureus (31 strains,accounted for 6.8%),coagulase negative Staphylococcus (22 strains,accounted for 4.9%),Enterococcus (18 strains,accounted for 4%).Meropenem,imipenem (Stenotroph-omonas maltophilia was excepted ) ,Cefoperazone /sulbactam and Amikacin were most sensitive against gram negative bacteria;Teicoplanin and vancomycin were highly sensitive against gram positive bacteria .Conclusion The main pathogenic bacteria of respiratory tract infection in ICU patients was gram negative bacilli ,which were seriously resist-ant to commonly used antimicrobial drugs .So strengthening the infection management of ICU and the control for risk factors,and rationally using of antimicrobial drugs has great significance in reducing the drug resistance of pathogenic bacteria rate .

Objective To establish a distinct linked emergency rescue network system in Shenzhen. Methods The current status of emergency network system in Shenzhen was studied, and some related publications in the recent years were reviewed. Results The emergency network system in Shenzhen is characterized by the following aspects: there is an effective emergency dispatch system with high authorities; the network covers every corner of Shenzhen; series of laws have been issued to ensure the proper operation of network. Conclusion The medical rescue system has developed in depth. The combination of community-based, pre-hospital and hospital rescue is effective in the whole process of emergency rescue, and shortens the rescue distance. The community-based rescue is the basic part of the system that can use the medical resources efficiently.

Objective To investigate the expression of matrix metalloproteinase-2(MMP-2) in the VX2 hepatic tumor.Methods 30 New Zealand white rabbit VX2 liver carcinoma models(all the tumors were verified by histopathology)were set up.The expressions of MMP-2 in 30 cases of VX2 tumor tissues and their pericarcinomatous tissues and normal hepatic tissues in 20 cases were detected by immunohistochemical staining with SP method at 2.5 weeks after implantation.The cell number of MMP-2 positive expression was counted by immunohistochemical stain.Results According to immunohistochemical results,the positiveness of MMP-2 was 86.7%(26/30) in tumor tissues and 53.3%(16/30) in pericarcinomatous tissues and no expressions of MMP-2 in normal hepatic tissues.The expression of MMP-2 were mainly in the tumor cytoplasm and intercellular substance,and also in the part of the tumor thrombi,the bile vessel epithelial cell and vascular endothelial cell.Conclusion The features of the expression of MMP-2 are similar to that of human HCC,and this model is a real animal model for clinical MMP-2 study of human HCC.

Objective To evaluate the safety of new-generation of antidepressants and amitriptyline in the treatment of depression in patients with coronary heart disease (CHD). Methods A total of 194 patients with first-episode depression with CHD were divided into amitriptyline group(n=40), venlafaxine group(n=40), mirtazapine group(n=48)and escitalo?pram group(n=66). The blood routine test, liver function, blood lipids and blood glucose (GLU) were monitored after treat?ment for six weeks, and which were compared before and after treatment. Results The levels of white blood cells (WBC) and neutrophil count (NE) were significantly lower in amitriptyline group after 6-week treatment (P<0.05), but the levels of acid alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (T-CHO) and GLU were significant?ly increased after treatment than those before treatment (P<0.05). The levels of WBC, NE and GLU were significantly de?creased in venlafaxine group after 6-week treatment (P<0.05). The levels of ALT, AST, low density lipoprotein (LDL) were significantly increased in mirtazapine group after six-week treatment (P<0.05). In escitalopram group, the level of three ac?yl glycerin (TG) was significantly increased after six-week treatment than before treatment ( P<0.05). There was a signifi?cant difference in AST change after treatment between venlafaxine group and mirtazapine group (P<0.05). There was a sig?nificant decrease in WBC in amitriptyline group than that of mirtazapine group after six-week treatment ( P<0.05). There was a significant decrease in NE in amitriptyline group than that of mirtazapine group and escitalopram group ( P<0.05). The increase level of AST was significant higher in amitriptyline group than that of venlafaxine group (P < 0.05). Conclusion Three different kinds of new-generation of antidepressants have fewer influence in routine blood test, liver function, blood lipids and blood glucose than those of amitriptyline in the treatment of depression in patients with CHD.
