Objective:To establish a new method to detect Amp C?-lactamase by PCR. Methods:The amp C and amp D gene fragments of E. cloacae were amplified by the amp C and amp D primers to detect Amp C ?-lactamase, especially the enduring and highly productive enzymes. Results:Totally 193 of 214 strains of E. cloacae were positive for amp C gene , implicating most strains of E. cloacae had the ability to produce the enzyme. Sixteen of the 193 strains (amp C positive) were negative for amp D genes, implicating these 16 strains could produce the enduring and highly productive enzymes. The results were confirmed by cefoxitin three-dimensional test. Conclusion:The new method to detect Amp C ?-lactamase, especially the enduring and highly productive enzymes,by amp C and amp D primers is a rapid and accurate method.

Objective To explore the mechanism of VEGF treating cerebral ischemia. Methods A rat model of middle cerebral artery occlusion (MCAO) was set up by nylon suture embolization. The naked plasmid DNA encoding vascular endothelial growth factor(pUCCAGGS/hVEGF 165 ) was directly injected through skull into the ischemic areas of brain. After seven days the rats were killed. RT-PCR was used to measure the expression of VEGF mRNA in the brain tissues, and immunohistochemistry was appllied to detect the expression of VEGF, Fas and Fas L in the brain tissues. Results Compared with control group, VEGF expression significantly increased in the therapeutic group(P

Objective To investigate blood flow dynamics adjacent to regional myocardial segments in coronary artery disease(CAD) patients and to explore the association of the two CAD features.Methods In 43 CAD patients,velocity vector imaging (VVI) was used to evaluate the wall motion and classify normal myocardial segments (NS),relatively abnormal and obviously abnormal wall motion segments (RS and OS) by systolic peak strain (Ss).Vector flow mapping (VFM) was used to show blood flow dynamics in the heart chamber,including blood flow (Q) heading towards or away from the apex during a heart beat and time to every peak flow (T).Results Compared with NS,both RS and OS showed a higher systole Q + (blood flow heading towards the apex during systole) and lower diastole Q + (blood flow heading towards the apex during diastole) and shortened T2 (adjusted time interval between E and A peaks).Systole Q + was positively correlated with Ss but negatively with segmental ejection fraction (SEF).Diastole Q + was negatively correlated with early and late diastolic peak velocity (Ve and Va) but positively with Ve/Va.T2 was negatively correlated with Ve but positively with Ve/Va and early diastolic peak strain rate (SRe).Conclusions VFM might be a new tool to quantitatively assess change in regional blood flow dynamics in patients with CAD.

Objective To evaluate the therapeutic efficacy of transcather arterial chemoembolization for hepatic carcinoma and its influence on hepatic function. Methods Patients with HCC were divided into three groups according to repeated TACE times. The therapeutic efficacy was assessed with survival rate, car-cionma size and biologic response (AFP). Hepatic function was evaluated according to some hepatic param-eters(ALT,AST,ALB,DB,TB,PT). Results All three groups responses rates were 4.3%, 23.1% and 31.6% ;srespectively,liver function in group 1 and group 2 returned to its pretreatment level(P <0.05) ,but in group 3, liver function did not return to its pretreatment level associated with more repeated TACE times. The 1-,2-and 3-year survival rates of group 1 were 27.0%, 10.8%, 5.4% ; respectively, while those of group 2 were 57.1%, 33.3%, 19.0% ; respectively, which were not significantly different from those of Team 3 ,which was 62.5%, 37.5%, 18.8%, respectively. Conclusions (1) three to four repeated times TACE was an effective palliative treatment that prolongs survival of patients with HCC,while 1 to 2 re-peated times had a limited benefit; (2) Irreversible hepatic impairment induced by TAEC could affect its therapeutic efficacy.

Objective To investigate the relationship between cancer-related fatigue (CRF) and quality of life (QOL) of the colorectal cancer patients.Methods In this study,patients diagnosed definitely as colorectal cancer were enrolled from November 2010 to January 2011 in this hospital.Piper Fatigue Scale was used to assess the CRF and QLQ-C30 was used to assess the QOL.Results 74 patients were enrolled in this study,and among them 28 patients had CRF(37.84％).Patients with CRF was significantly worse in QOL than patients without CRF.Physical function,role function,emotional function,social function and the general health subscale had a negative correlation with CRF,while pain,fatigue and loss of appetite had a positive correlation with it.Conclusions CRF had an impact on QOL,and this study will provide some reference information when the nurses take measures to intervene CRF and improve QOL of the colorectal cancer patients.

Objective To analyze on the efficacy and toxicity of MAAE (MIT ,Ara-C,AMSA,VP16)regimens on treating refractory and relapsed acute leukemia in adult patients.

Objective To explore the effects of two-dimensional code on nursing instruments management.Methods Information regarding nursing instruments were edited and corresponding two-dimensional codes were generated which would be pasted on both the instruments and the registration book,and nurses were notified about the twodimensional codes.The effects of the application of two-dimensional code were assessed among 145 nurses using questionnaires,and 40 nurses were evaluated for theoretical and operational skills of the instrument.Results After applying two-dimensional code in management of nursing instruments,nurses' scores for utilizing,maintenance,addressing malfunction,storage and counting were higher than previous management method for instruments(P＜0.05),and the performance of theoretical and operational skills of 40 nurses were increased significantly(P＜0.05).Conclusion Two-dimensional code provides valuable benefits for information storage,instrument tracking,etc.,shows great convenience and efficiency to nursing instruments management,and helps to improve nurses' application skills of instruments.

Objective To investigate the relationship between antipituitary antibodies (APAs) and hypopituiarism following traumatic brain injury (TBI),as well as the severity of brain injury.Methods The study included 73 patients who suffered TBI 9 to 12 months ago and were diagnosed with hypopituitarism during the follow-up.Based on their Glasgow Coma Scale (GCS) on admission they were categorized into three groups:A (3-8),B (9-12) and C (13-15).Levels of plasma pituitary hormones (GH,TT,FT3 and FSH/LH) and APAs were measured in all patients with chemiluminescence assays and ELISA,respectively.Results Patients in group A had higher levels of APAs and lower levels of hormones compared with those in group B(P＜0.001) or group C(P＜0.001),while no significant difference was found between group B and group C for levels of either APAs (P＞0.05) or hormones (P＞0.05).Levels of APAs were negatively correlated with both GH (r=-0.64071,P＜0.001) and GCS (r=-0.50132,P＜0.001).Conclusion The present investigation provides preliminary evidence that APAs may be associated with the development of TBI-induced hypopituiarism.It suggests that the severity of hypopituiarism following TBI could be predicted by measuring the level of APAs.

Objective To explore the method and efficiency of percutaneous transluminal septal tunnet myocardial ablation(PTSTMA) in treatment of 26 cases hypertrophic obstructive cardiomyopathy (HOCM) who were not suitable for conventional technology.Methods Firstly,we used a monorail Balloon which was slightly bigger than the interventricular septal branch of coronary artery and dilated it until posterior septal.After that,an OTW Balloon with larger size than the monorail was used to dilate again until made aventricular septum tunnel.Then,some alcohol was injected and PTSTMA was performed.Finally,we did the other and/or another interventricular septal branch by above method until the left ventricular outflow tract pressure gradient (LVOTPG) reduced ≥50％.The clinical indexes of the 26 cases HOCM immediately pest-operation of PTSTMA were observed and the follow up data during short term and metaphase were analyzed.Results The LVOTPG reduced ≥50％ in the26 cases HOCM,immediately after PTSTMA,the LVOTPG reduced from (75.6 ±22.4)mm Hg to (21.4 ± 5.8) mm Hg (t =11.94,P ＜ 0.01).At three months after ablation,the thickness of septal myocardium reduced from (22.8 ± 5.8) ram before ablation to (16.8 ± 4.2) mm(t =4.27,P ＜ 0.01),left atrium dimension reduced from(48.0 ±7.0) mm to (42.0 ±8.6) mm (t =2.76,P ＜0.01).Followed up 6.0to 60.0 months,the patients suffering from chest pain reduced from 14 cases before to 4 cases after the procedure(53.8％ (14/26) vs 15.4％ (4/26),x2 =8.49,P ＜ 0.01),the patients with expiratory dyspnea reduced from 26 cases to 5 cases(100％ (26/26) vs 19.2％ (5/26),x2 =35.22,P ＜ 0.01),NYHA functional class improved from (2.4 ± 0.6) to (1.4 ± 0.7) (t =5.53,P ＜ 0.01).Conclusion The PTSTMA was a supplemental method of PTSMA on treating HOCM,which was safe and useful during the short term and metaphase.
