Objective To compare the outcomes of off-pump versus on-pump CABG.Methods From 2002 to 2008,CABG was performed in 105 patients aged 80 years and over,including 45 without cardiopulmonary bypass (CPB) or off-pump (OP) CABG (OPCAB) and 60 with CPB (onpump CABG).The outcomes were compared between two groups.Results The mean ICU stay was (37.1±30.3) h in OPCAB group and (60.6±58.2) h in on-pump CABG group (P＜0.01).Average ventilator-assisted time was (10.8±9.7) h for OPCAB group versus (22.3±35.7) h for onpump CABG group (P＜0.01).Postoperative atrial fibrillation occurred in 31.1％ of OPCABG patients and 41.7 ％ of on-pump CABG patients (P＜0.01).The mortality rate was 5.0％ in OPCABG group versus 8.3％ in on-pump CABG group (P＜0.05).Conclusions OPCABG is a safe and efficient method of myocardial revascularization in the elderly patients with lower morbidity and complications.

Objective To study the diagnostic value of serologic intestinal-fatty acid binding protein (i-FABP) in neonatal necrotizing enterocolitis (NEC).Method The standard search strategy included electronic search and manual search.Electronic search was carried out in databases including PubMed,Ovid,Cochrane Library,Chinese Biomedicine Database (CBM),CNKI,WANFANG DATA and VIP database.As a supplement,relevant references from previous reviews and studies were examined by manual search.Two independent reviewers assessed the quality of included studies and extracted data,and performed further meta-analysis.RevManS.3.5 and Meta-Disc1.4 and Stata12.0 were used in the statistical analysis.Result A total of 11 studies with 700 cases were identified,including 308 NEC cases and 392 control cases.The blood samples collected at the time of suspected NEC stage showed pooled sensitivity 0.56 (95％ CI 0.44 ～ 0.67),pooled specificity 0.93 (95 ％ CI0.87 ～ 0.97),area under curve (AUC) =0.8282,and Q* =0.7610,respectively.The blood samples collected after clinical diagnosis of NEC showed pooled sensitivity 0.78 (95％ CI 0.72 ～ 0.83),pooled specificity 0.81 (95％ CI 0.76 ～ 0.86),AUC =0.8680,and Q* =0.7985,respectively.Conclusion i-FABP is a valid serologic biomarker for early diagnosis of NEC in neonatal infants.

Objective To investigate the influence of CT-guided thermochemotherapy for pig's healthy pancreas and in turn to discuss the feasibility and efficacy on pancreatic tumors.Methods 9 healthy pigs were undergone CT-guided 80℃themochemotherapy with 18 G fine meedle injecting individually of 5-Fu 750mg(10 ml)into the pancreatic tail within 2min.CT,MRI and serum analyses test were carried out as the follow up study at 1h,3rd,7th and 14th day after the procedure;since the 3rd day,3 pigs were sacrificed right after every follow up and together with comparative study between diagnostic imagings and pathologic changes. Results The pig pancreatic tail necrotic lesions appeared to be most conspicuous at the 3rd day after thermochemotherapy and shrank gradually from 7th day to 14th day.Serum amylase level reached the highest at 3rd day after the treatment and lowered down at 7th day;and near approximately normal at 14th day.The outcomings of diagnostic imagings and macroscopic pathology were in accordance.Obvious pancreatitis occurred only in one pig and all others were nearly uneventful without serious complications of pancreatitis,intestinal adhesion and mortaligy.Conclusion CT-guided themochemotherapy can induce pancreatic,focal necrosis in healthy pig but with no serious complications;and these can further more establish the foundation for clinical practiee.(J Intervent Radiol,2007,16:844-846)

To develop an oral drug,ITF gene encoding ITF proein,was expressed in a live delivery vehicle lactococcus lactis.First,the ITF gene was cloned into the prokaryotic expressive vector pNICE:sec.Second,the recombinant vector pNICE:sec-ITF was transformated into Lactococcus lactis strain NZ9000 to express ITF protein.Then the recombinant ITF was induced to express and was identified by SDS-PAGE and Western blot.Rabbits are divided into blank control group,preparation group and therapeutic group which are respectively administrated wih PBS and pNICE:sec-ITF Lactococcus lactis.By grades of ulcer test whether administrated pNICE:sec-ITF Lactococcus lactis protects against HCl-induced gastric injury in rabbits.The results were described as follows.The ITF was amplified and cloned in the vector pNICE:sec successfully.The fusion protein(5.9kDa) was expressed in L.lactis by the induction of the nisin.The quantity of expression accounted for 5% of the total bacterial protein.Western bolt analysis confirmed that fusion protein could be recognized specially by Monoclonal Anti-human TFF3 Antibody.Preparation groups and therapeutic groups do good than control group.Prove that administrated pNICE:sec-ITF Lactococcus lactis is biologically active in an HCl-induced rabbit gastric mucosal injury model.

OBJECTIVE: To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence. METHODS: The rat heroin dependent model was established by increasing intraperitoneal injection of heroin. DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group. RESULTS: DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time. CONCLUSION Heroin dependence can affect postsynaptic density of hippocampus, amygdala and frontal cortex. The changes become more apparent with extension of heroin dependence time.

OBJECTIVETo investigate the pathogenic infection and its drug resistance in expressed prostatic secretion (EPS) and its correlation with serum PSA, and provide some evidence for the systematic and normalized diagnosis and treatment of prostatitis.

METHODSThree EPS swabs were collected from each of the 320 prostatis patients following measurement of the serum PSA level, 1 for bacterial culture and identification, 1 for detection of Mycoplasma and drug sensitivity, and the other for examination of Chlamydia trachomatis antigen by colloidal gold immunoblot.

RESULTSTotally 244 strains were isolated from the 320 EPS samples, including 188 bacterial strains (dominated by Staphylococcus and sensitive to vancomycin or linezolid) and 44 Mycoplasma and Chlamydia strains (mainly Ureaplasma urealyticum and susceptible to josamycin or doxycycline). The serum PSA level was significantly higher in the pathogen-positive than in the pathogen-negative group ([6.98 +/- 0.56] microg/L vs [2.32 +/- 0.12] microg/L, P < 0.05).

CONCLUSIONProstatitis may lead to the elevation of the serum PSA level and the pathogens involved vary in their resistance to different antibacterial spectrums. Therefore, appropriate and individualized antibiotic therapy should be selected according to etiological diagnosis and the results of drug sensitivity test.
