BACKGROUND: This study aimed at identifying the effects of improved methods of endotracheal suction and hand washing on incidence of nosocomial pneumonia (NP) in the neurosurgical ICU. METHOD: Repeated training of nurses about hand washing and adherence of the single use of suction catheter and sterile normal saline of endotracheal suction was provided. Then hand washing compliance of nurses before and after training was investigated. and the incidence of NP in all patients hospitalized for more than 72 hours in the neurosurgical ICU was investigated from Sep 1, 2000 to Jan 31, 2001 (2nd surveillance). The NP rate of that period was compared with the incidence of the 1st surveillance period, from Sep 1, 1999 to Jan 31, 2000. The data were analyzed with chi-square-test. Fisher's exact test and logistic regression analysis by SAS 8.0. RESULT: The proportion of hand washing performance increased from 15.6% to 46.8%. The rates of NP per patient during 1st surveillance and 2nd surveillance were 10.3%, 3.9%(p=0.01) patient-days rates of NP were 10.0 cases/1,000 patient days, 4.1 cases/1,000 patient days(p=0.04), and ventilator-days rates of NP were 67.6 cases/1.000 ventilator days, 16.2 cases/1,000 ventilator days(p=0.00) respectively. Out of 29 isolates, 18 were methicillin-resistant Staphylococcus aureus, which was the most frequently isolated microorganism. The risk factors associated with incidence of NP were age, length of stay, Glasgow coma scale, diabetes mellitus, duration of intubation, insertion of endotracheal tube, duration of tracheostomy, presence of tracheostomy, duration of ventilator, use of ventilator, and insertion of nasogastric tube. CONCLUSION: These results showed that single use of suction catheters and sterile normal saline and increased compliance of hand washing were important factors to decrease the incidence of NP.

Objective To study the corelation between the expression of COX-2 and postoperative adhesions and to determine the effect of COX-2 selective inhibitor,Celecoxib,on postoperative adhesion formation. Methods Fifty SD rats were randomly assigned to five groups each consisting of 10 rats,Study groups were as follows:(A)positive control group,(B)sodiumhyahronate group,(C)low dose Celecoxib group,(D)high dose Celecexib group,(E)negative control group,Five rats in each group were treated accordingly for consecutive 8 days and 15 days respectively and sacrificed,After treatment,intra-abdminal adhesions were scored using a standard method.The adhesions tissure and injured peritonaeum were subjected to Westem-blotting to detect the expression of COX-2. Results The level of postoperative adhesions and expression of COX-2 of sodiumhyahronate group、low dose Celecoxib group、high dose Celecoxib group were lower than that of positive control group(P<0.05),Sediumhyahronate treatment group was different formthe two Celecoxib treated groups(P<0.05).Conclusions Selective COX-2COX-2.mechanism,provides durable inhibition of intra-abdominal adhesions through an antiangiongenic COX-2 mechanism.

Aim To establish hyperlipidemic model and study the molecular mechanism of triglyceride (TG)disorder in hamsters.Methods The male ham-sters were randomly divided to control group fed with standard diet and model group fed with high-fat diet, both of the groups had been fed with diet for 4 weeks. The levels of serum TG,TC,LDL-C,FFA were detec-ted at the end of 2nd and 4th week.The hepatic TG, TC,LPL activity were detected by enzymatic method at the end of 4th week.The molecular mechanism was tested by real-time PCR.Meanwhile the effect of posi-tive drug fenofibrate on the model of hyperlipidemia in hamsters was investigated.Results Compared with the control,the serum levels of TG,TC,LDL-C,FFA in the model group increased 2.57,1.93,2.49,1.25 times at the end of2nd week,and 3.93,1.90,2.27, 2.29 times at the end of 4th week,respectively.The positive drug significantly decreased the concentrations of serum TG and FFA. The mechanism research showed that the hepatic AMPK,PPARα,CPT-1 mRNA decreased in hamsters fed with high-fat diet,and the SREBP-1 c,ACC,SCD-1 ,AGPAT2,DGAT2 mRNA ex-pressions increased.The hepatic ApoB mRNA expres-sion was up-regulated while the MTTP and LPL mRNA expressions were down-regulated slightly.LPL activity significantly decreased in model hamsters compared with the control.The alternations of these enzymes and receptors were the critical factors for TG disorder. Conclusion The hamsters fed with high-fat diet for 4 weeks can form a good hyperlipemic model with HTG feature.AMPK,SREBP-1 c,ACC,SCD-1 ,DGAT2,AG-PAT2,PPARα,CPT-1 and LPL are not only the main mechanisms of TG disorder,but also the biomarkers of hypotriglyceridemic drugs.

Aim To establish the hyperlipidemic model and ex-plore the mechanism of hypercholesterolemia in hamster. Meth-ods Hamsters were randomly divided into the control and model groups. The hamsters in the control group were fed with the standard chow and the model group were fed with the high fat di-et. Serum lipids and CYP7A1 activity were detected by enzymat-ic method. The molecular mechanism of cholesterol metabolism was investigated by real-time PCR. Results In comparison with the control group, the concentrations of serum TC, LDL-C, TG and hepatic TC, TG were significantly increased in the model
group. The mechanism research showed that in hamsters fed with the high fat diet, the CYP7A1 activity and the mRNA expres-sions of hepatic LDL-R, SREBP-2, CYP7A1, LXRαwere down-regulated, the expression of hepatic FXR was up-regulated. Conclusion The hyperlipidemic model could be developed in hamsters fed with the high fat diet for 4 weeks. LDL-R, SREBP-2, CYP7A1, FXR and LXRαare the biomarkers of hypercholes-terolemia, and also the targets of hypolipidemic drugs.

OBJECTIVETo investigate the clinical effects of anterior cervical intervertebral space decompression under microscope in treating cervical spondylotic myelopathy in elderly patients.

METHODSFrom June 2009 to March 2012, 43 patients with cervical spondylotic myelopathy were treated with anterior cervical intervertebral space decompression and intervertebral fusion under microscope. There were 26 males and 17 females, aged from 60 to 72 years old with an average of (64.9±3.7) years. Japanese Orthopaedic Association System (JOA) score was from 7 to 12 points with an average of (9.5±1.8) points before operation. The function of nerves was assessed before and after operation according to JOA.

RESULTSAll patients were followed up from 10 to 18 months with an average of (14.7±1.6) months. Postoperative JOA score was (13.81±1.44) points (ranged, 10 to 16), had significantly higher than preoperative (P<0.01). According to the rate of the improved JOA score, 9 cases got excellent results, 26 good, 7 fair, 1 poor.

CONCLUSIONAnterior cervical intervertebral space decompression under microscope for cervical spondylotic myelopathy in elderly patients is safe and effective.

Objective To identify the important risk factors for type 2 Diabetes Mellitus (T2DM) and develop effective strategies to address the problem of T2DM.Our study aimed to evaluate the association between apolipoprotein E (ApoE) genetic polymorphism and type 2 diabetes,and to provide clues for the etiology of T2DM.Methods Based on the criteria of inclusion and exclusion,we extracted,pooled,analyzed and assessed the case-control studies of ApoE polymorphism and T2DM published in PubMed,Web of Science,Medline,WanFang,VIP,and CNKI databases by R soft-ware (version 3.4.3).We used Random-effect models when heterogeneity was present in between-study,and fixed-effect models otherwise.Results We had 59 studies covering 6,872 cases with T2DM and 8,250 controls,and compared the alleles and genotypes of ApoE between cases and controls.When we conducted a comparison between ApoE ε4 and ε3 alleles,we produced a pooled OR of 1.18 (95％ CI:1.09-1.28;P ＜ 0.001).ApoE ε2/ε2 genotype displayed a possible association with T2DM (OR =1.46;95％ CI:1.11-1.93;P =0.007),ε3/ε4 genotype showed a 1.11-fold risk (OR =1.11;95％ CI:1.01-1.22;P =0.039) and ε4/ε4 genotype had a 1.71-fold risk of developing T2DM (OR =1.71;95％ CI:1.33-2.19;P ＜ 0.001) when they were compared with ε3/ε3 genotype.Conclusions There is an association between ApoE polymorphism and T2DM:allele ε4 and genotypes (ε2/ε2,ε3/ε4,and ε4/ε4) are associated with the increased risk for the development of T2DM,and they may be risk factors for T2DM.

Supernumerary kidney is one of the very rare anomalies of the urinary tract. Only about 75 cases have been reported since it was first described in 1656. Herein we present a case of supernumerary kidney which was diagnosed by ultrasonography, intravenous urography and CT scanning.
