Objective To observe the therapeutic effect of porcine myocardium against porcine myocardial infarction (MI) by porcine myocardial infarction model with connexin-43/zonula occludens-1 (CX43/ZO-1) double gene induced pluripotent stem cells (iPS) transplantation.Methods Porcine myocardial infarction model was established by balloon occlusion.One week later,1640 culture medium,CX43 gene ips cells and CX43/ZO-1 gene ips cells were injected into the different coronary arteries.After 3 months,electron microscopy and color Doppler ultrasonography were used to evaluate the curative effect.Results Compared to ips group of CX43 and 1640 culture group,in CX43/ZO-1 gene ips group,electron microscope showed a large number of island-like cardiomyocytes,blood vessels and intact intercalated discs in the infarct area and normal myocardial junction area structure,color Doppler echocardiography showed left ventricular end diastolic diameter reduced,and ejection fraction was significantly increased (P < 0.05).Conclusions Transfection of CX43/ZO-1 double gene ips cells can promote cardiomyocyte regeneration and cardiac function recovery in porcine myocardial infarction model.

Objective To investigate prevalence of resistance genes for β-lactams in clinically isolated multidrug-resistant Acinetobacter baumannii (MDRAB)in a hospital.Methods 22 clinically isolated MDRAB strains were performed antimicrobial susceptibility testing,resistance genes forβ-lactams (TEM,SHV,CTX-M,PER,DHA, IMP ,VIM ,SIM,OXA-23,OXA-24,and OXA-58)in these strains were detected with polymerase chain reaction. Results The resistant rates of 22 isolates of MDRAB to ceftazidime,cefotaxime,cefepime,gentamycin,amikacin, ciprofloxacin,and compound sulfamethoxazole were all 100.00%;to imipenem,meropenem,and cefoperazone/sul-bactam were 50.00%,40.91 %,and 31 .82% respectively,intermediated rates were 31 .82%,36.36%,and 31 .82% respectively.The carriage rates of OXA-23,TEM,IMP ,and PER were 100.00% (n =22),72.73 %(n=16),54.55% (n = 12),and 18.18% (n =4)respectively.Detection results of SHV,CTX-M,DHA,VIM , SIM,OXA-24,and OXA-58 were all negative.Conclusion Carriage of IMP ,TEM,PER,and OXA-23 resistance genes are the major resistance mechanisms of MDRAB to β-lactamase antimicrobial agents in this hospital.

This paper discussed the existing problems of Information System ( LIS) from six aspects, inclu-ding:the security and the expansion of the function, protection of patients′privacy, the establishment of emergency response mechanisms, authenticity and accuracy of data and the risks for auto-approval rules, etc.The authors also analysed the necessity of its rectification from the perspective of ethics, proposed improvement programme and suggestions: strengthening the safety management systems and data, ensuring special check the confidentiality of the project, protect the patient′s privacy;setting up emergency mechanism;hospital based on the actual workload and resources to determine the LIS function module; regularly checking the test data, to avoid occupational inju-ries;continuously improving the rigour of automatic approval rules.

Objective To identify an suspected Vibrio cholerae isolated from Xiangyang Central Hospital and characterize the strain in terms of antibiotic resistance and relevant virulence genes.Methods Pathogen identification and susceptibility testing were completed with MicroScan WalkAway 40 Automated Microbiology System.Slide agglutination was used for serotyping. PCR and sequencing technology were employed for 16s RNA gene analysis.PCR technique was used to detect six major viru-lence genes.Results This suspectedVibrio cholerae isolate was confirmed as non-O1 and non-O139 Vibrio cholerae .Suscep-tibility testing results indicated that the strain was sensitive to ampicillin,chloramphenicol,trimethoprim-sulfamethoxazole, and tetracycline.16s RNA gene sequence analysis showed 100% homologous with the registered sequence in National Center for Biotechnology Information database.Virulence genes rtxC and toxR were identified.The other virulence genes such as tcpAET,ctxA,hlyA,and tcpACL were negative.Conclusions This suspected Vibrio cholerae isolate is confirmed as non-O1 and non-O139 Vibrio cholerae .The pathogenic factors may be related to the virulence genes rtxC and toxR.

Objecitve To observe the diffusion and distribution of imported Oncomdania snails in non-endemic areas of schistosomiasis.so as to provide scientific basis for developing the scheme of snail surveillance.Methods Oncomelania snails from the msrshland of Dongting Lake were imported in a waste land in March,2008,Qingxin County,which belonged to non-endemic areas of schistosomiasis.and their diffusion and distribution condition were observed from May to December in the same year.Resuits A total of 1 600 Oncomelania snails were imported.The occurrence rate of frame with snails in sunny days and cloudy rainy days were22.88%and 29.24%,respectively,and there was a statistically significant difference between them(χ~2=4.113,P=0.043).Those in waste Land and the sides/bottoms of the ditches were 9.38%and 35.99%,respectively,and the difference between them also showed a statistical significance(χ~2=67.246,P<0.001).The average density of living snails in sunny days and cloudy rainy days were 0.79 and 1.11 No./0.1 m~2,respectively,and those in waste land and the sides/bottoms of the ditches were0.11 and 1.34 No./0.1 m~2.The furthest diffusion distance of snailswas 4.5 m.Conclusions The detective opportunity of imported snails is relatively high in cloudy rainy days,which mainly distribute at the sides/bottoms of ditches and diffuse along the ditches.

Our experiment aims to compare the effects of "energy-containing lactated Ringer's solution"(EL-RS) with those of "lactated Ringer's solution" (LRS) as an initial resuscitation fluid for the treatment of traumatic shock in rabbits. Deep shock animal models were produced in 74 adult rabbits using the method of pincers pressure and Wiggers' hemorrhagic shock method to produce crush injury of the soft tissue on the thigh and comminuted fracture of the femur. Results showed that blood pressure of the experimental group rose more rapidly than control group and the survival time of the former were longer than the later. The lowering of serum lactate and blood pH etc. showed a similar difference. It is suggested that ELRS is more efficient than LRS for the treatment of traumatic shock in rabbits.
