Objective To evaluate the cost-effectiveness of early enteral nutrition (EEN) in elder patients undergoing gastrectomy for gastric carcinoma. Methods An outcome-based retrospective review of 52 patients who had undergone gastrectomy for gastric carcinoma between July 1999 and June 2002 was performed .There were 27 patients in the EEN group, and 25 in the TPN group. Results The mean postoperative hospital days of the EEN group was significantly less than that of the TPN group (16.3 d vs. 21.3 d, t =4.6814, P

BACKGROUND: Diabetes mellitus is a chronic metabolic disease caused by various factors,such as environmental factor,inherited factor,etc.,and its cause isn't very clear now. This study aims to investigate the risk factors mentioned above in the onset of diabetes mellitus, and is of significance in the first and second grade of prevention of diabetes mellitus.OBJECTIVE: To investigate the risk factors of type 2 diabetes mellitus to provide evidence for the proper intervention of it.DESIGN: Cross-sectional study based on diagnosis.SETTING: Department of epidemiology in a university and department of endocrinology in a university hospital.PARTICIPANTS: The subjects were residents who have resided in town and country of Dalian for more than 5 years and were elder than 40 years old. The method of stratified cluster random sampling was carried out among natural persons who were divided into two groups according to city and country. Totally 2 500 persons were taken in total and 1 250 persons were from each group. The subjects who had been diagnosed as diabetes mellitus were included.METHODS: Questionnaire survey was employed for all the subjects, including physical examinations such as height,weight,waist girth,hip girth,blood pressure,blood glucose,etc. Patients of type 2 diabetes mellitus were taken as the case group and the normal was as the control group. The unconditional univariate and multivariate logistic regression were used.MAIN OUTCOME MEASURES: Unconditional logistic regression analysis of risk factors of type 2 diabetes mellitus with single factor analysis and multivariate analysis.RESULTS: Family history of diabetes mellitus(OR = 2.339),obesity[body mass index(BMI),OR = 1.462],systolic pressure(OR = 1.016),hyperlipidemia(OR = 1.615), age(OR = 1.043) were the major risk factors for type 2 diabetes mellitus.CONCLUSION: Family history of diabetes mellitus, increase of systolic pressure,obesity,high blood lipid and age are the risk factor for type 2 diabetes mellitus. For all communities,control of body mass and high blood pressure is an important way to prevent type 2 diabetes mellitus.

The paper reported an investigation of the pharmacokinetics of SN-38 (7-ethyl-10-hydroxy-camptothecin) in rats and the tissue distribution in mice after injection of irinotecan hydrochloride nanoparticles (CPT-11) via tail veins. An LC-MS/MS method was established to determine the concentrations of SN-38 in whole blood of rats and in different tissues of mice. The pharmacokinetics and tissue distribution of SN-38 were compared after the intravenous injection of CPT-11 NPs and CPT-11 solution. Compared with irinotecan solution, the elimination half-life of SN-38 was prolonged from 2.17 h to 2.67 h after the intravenous injection of CPT-11 NPs, but its AUC had little change. After the injection of CPT-11 NPs in mice, over time, the concentrations of CPT-11-metabolized SN-38 in CPT-11 NPs were significantly higher in the whole blood, colon and lungs than those in CPT-11 solution, followed by in the spleen and liver, but those in the heart and brain had no change. However, the amount of SN-38 in the kidneys was reduced with time. CPT-11 NPs could prolong SN-38's (one of its metabolites) blood circulation time in rats and significantly increased the concentration of CPT-11-metabolized SN-38 in the whole blood, colon and lungs of mice. CPT-11 NPs made SN-38 efficiently target-bind to the colon and lungs of mice.

Complex genetic variation has been known to occur during the transmission of human enterovirus (HEV), and the HEV virulence and pathogenicity enhanced by genetic recombination also pose a serious threat to human health. In recent years, the interest in recombination mechanism of genetic plasticity has been renewed with the emergence of pathogenic recombinant circulating vaccine-derived polioviruses, which were implicated in poliomyelitis outbreaks in several regions of the world with insufficient vaccination coverage. This paper reviews recent research progress in HEV genome, including evolutionary characteristics, recombination types, and in vitro recombinant construction.

Objective To detect the sera anti-enteric neuronal antibodies ( AENA ) in irritable bowel syndrome with diarrhea ( IBS-D) patients and analyzed its correlation with IBS-D symptoms to explore the potential roles of AENA in the pathogenesis of IBS.Methods IBS-D patients diagnosed with RomeⅢdiagnostic criteria were en-rolled in this study.The sera of healthy subjects were used as controls.Indirect immunofluorescence ( IIF) was used to detect the sera AENA with the substrate of ileal submucosal plexus of guinea pig .The immune reactivity ( IR) stains were read in blinded method .The bowel symptoms of patients with positive AENA were compared to thatwithnegativeandweeklypositiveantibodies.Results 1)Atotalof127IBS-Dpatientswereenrolledinthis study.The positive rate of sera AENA was 85.8%in IBS-D patients, and 7.0%in healthy controls.Among 109 IBS-D patients with positive IIF reactivity , 23.6%present with strong positive , 43.3% with positive and 18.9%with weakly positive stain .The IR patterns included cytoplasm staining , nucleus staining , cytoplasms and nuclei staining , nuclear membrane staining , cytoplasm and nuclear membrane staining .Six positive sera of healthy control showed cytoplasm staining to substrate neurons .2 ) More patients of IBS-D with positive IR had higher intestinal symptoms scores (>10 scores, 58.8%vs 38.1%), frequent abdominal pain in non-defecation period (91.7%vs 60.0%) , and severe abdominal pain/discomfort before defecation ( 24.7% vs 9.5%) comparing to those with negative and weekly positive IR of AENA;IBS-D patients with positive IR of AENA are more commonly associated with urgency comparing to those with negative IR in IIF (57.1%vs 87.3 ) .Conclusions AENA may play a role in the pathogenesis of IBS , and is a potential biomarker of IBS-D.

3 month),fluid sign was observed in 2(3 vertebrae,3/26,11.5%). Conclusion Fluid sign is characteristic in acute,subacute and early chronic trauma vertebral compression fracture for bone marrow edema,while it is rare in metastatic tumor vertebral compression fracture.It may paly a role in the differentiation of benign and malignant vertebral compression fracture.
