Objective To understand the freshmen’s status of hepatitis B virus infection,immunological effect after vaccina-tion against hepatitis B from a university in Ankang city,to provide a scientific basis for university’s prevention from hepati-tis B.Methods Analyzed the results of five markers of hepatitis B virus infection and alanine aminotransferase (ALT)of 25 895 freshmen in a college in Ankang for resent 12 years,and observed the HBsAb serocoversion in serum 1 year after vacci-nation against hepatitis B and after strengthened immunity.Results The HBeAg positive rate of the freshmen was 4.07%, among which the male was 5.58% (281/5 035),and the female was 3.14% (258/8 214).The difference had significance of statistic (P<0.05).The college students’HBeAg positive rate from rural area and from urban area were 4.77% and 2.93%respectively,the difference had significance of statistic (P<0.05).There was no significant statistic difference in immune effect of hepatitis B vaccine for different sex (χ2=5.80,P<0.05).Their HBsAb positive rate was 95.15% after injected with 10μg hepatitis B and 5μg hepatitis B vaccine,which had significance of statistic (P<0.05).Conclusion The hepatitis B virus infection rate and the hepatitis B protective antibody of the college freshmen in Ankang district was lower than that of the whole country and had a decreased tendency.It showed the male’s infection rate of hepatitis B virus was higher than the female,the rural was higher than the urban,and the immune effect of hepatitis B vaccine proved to be good.It should be-strengthened immunity for non-responders to ensure the immune effect if necessary.

Objective To clarify the clinical features of solid pseudo-papillary tumor of pancreas. Methods Clinical data of 38 patients with solid pseudo-papillary tumor of pancreas were analyzed retrospectively. Results The clinical manifestations included a palpable abdominal mass, abdominal pain and discomfort. Tumor occured in 1 case younger than 10 years old, 11 cases between 11 years old and 20 years old, 7 cases between 21 years old and 30 years old, 9 cases between 31 years old and 40 years old, 5 cases between 41 years old and 50 years old and 1 case older than 50 years. Immunohistochemistry staining showed CgA( + ) in 6 cases,Vim( + )in 29 cases,AAT( + ) in 29 cases,Syn( + ) in 21cases,CD10( + ) in 34 cases,CD56( + ) in 37 cases, Ki-67 ( + ) in 36 cases and PR( + ) in 38 cases. Conclusion Solid pseudo-papillary tumor of pancreas is closely associated with gonadal hormone and reproductive system.

Objective To explore the effect of evidence-based care on the constipation of psychiatric patients.Methods The constipations in 328 psychiatric patients admitted to our department were intervened with evidence-based nursing.Frequency for defecation,incidence of difficult defecation and incidence of dry stool before intervention were compared to those two weeks after intervention.Result Two weeks after intervention,the defecation frequency,incidence of difficult defecation and incidence of dry stool were all significantly lower than those before the intervention(P<0.001).Conclusions The evidence-based nursing used in care to psychiatric patients with constipation can reduce the incidence of constipation,and relieve their physiological and psychological pains.

Objective To investigate the changes and clinical significance of platelets aggregation rate of patients with coronary heart disease before and after percutaneous transluminal coronary stenting Methods There are 13 patients underwent coronary angiography and 20 patients underwent percutaneous transluminal coronary stenting Their blood samples were taken from the coronary sinus and coronary artery before and after interventional therapy Results The level of platelets aggregation rate in percutaneous transluminal coronary stenting group was higher after interventional therapy ( P

0.05). No procedure related complications and malignant arrhythmia were found during 6-12 months follow-up. Conclusion Intracoronary transplantation of ABMMNCs is safe and may improve the heart function.

To improve the science principle of input-output evaluation in medical research institutions,this study uses literature research and expert interviews to make a comparison between domestic and foreign evaluation criterion.There are several problems about input-output evaluation in medical research institutions in China,such as less flexibility and targeted methods,inappropriate models,inadequate indicators and quantitative metrics.Seveal combinations of elements should be considered for input-output evaluation in medical research institutions,which is parallels and distinctions,qualitative and quantitative methods,quality and quantity,process and results,focus and full,and also emphasis on the application of information technology.

0.05).Conclusion Intracoronary transplantation of ABMMNCs may not improve the heart function of DCM with abnormal Q wave.

Objective To establish a simple and quick method to determine methamidophos in human serum samples. Methods The samples were extracted by acetone and were separated with centrifuge then were determined by gas chromatography (GC-FPD). Results The determine limit for methamidophos in human serum was 0.05 ng. The minimum determine concentration was 0.40 ?g/ml. Rate of recovery of methamidophos added in human serum were 90.5%-105.6%. The relative standard deviations (RSD) were 4.52%-6.63%. Conclusion This method is sensitive, accurate and reliable for the determination of methamidophos in human serum samples.

Background and purpose:Blood biochemistry and ascites test, imageology examination has low sensitivity in abdominal neoplasmas diagnosis. And also exploratory laparotomy is not suitable for final stage patients. Mini-laparoscopy has been a new diagnostic technology for abdominal disease recently. We aimed was to evaluate the value of Mini-laparoscopy in diagnosing Abdominal Neoplasms. Methods:By reviewing the clinical and operational data, a retrospective analysis of 20 cases with pathologically confirmed abdominal malignancies was performed. Among this group, 10 cases were diagnosed by mini-laparoscopy, and the other 10 cases by exploratory laparotomy. Between the two groups, the surgical expense, anesthesia cost, para-operation nursing, monitoring and treating charges, post- operative hospital days and complications were compared. Results:Comparing mini-laparoscopy to exploratory laparotomy, the surgical and anesthesia charges were statistically lowered (P

Objective To investigate the degradation rate of profenofos in soil. Methods The residues of profenofos at different times after spraying on soil were determined by GC-FPD method. Results Detection limit of profenofos in soil was 0.04 mg/kg. The recovery rates and relative standard deviation obtained by adding standard assay were 95.2%～98.7% and 3.4%～4.5% respectively. According to the dose recommended, degradation of profenofos sprayed on soil was consistent with one range dynamics. The half-life of profenofos in soil was 1.09 days. At the 13th day after spraying on soil, 98.3% of profenofos had degraded. Conclusion This method was simple, rapid, accurate and precise. The degradation of profenofos was more rapid and profenofos contamination in soil was not a serious problem.
