Objective To investigate the positive rates of HBsAg and abnormal rates of Alanine aminotransferase among high school graduates in Jingjiang city.Methods HBsAg were detected by ELISA and ALT was detected by rate assay among 20 988 high school graduates during 2004—2007 in Jingjiang city.Results The HBsAg positive students were 1754.The total positive rate of HBsAg was 8.36%.The positive rate of HBsAg of male(9.46%)was higher than that of female(6.95%).The HBsAg positive rate of rural students(9.44%)was higher than that of urban students(7.28%).HBsAg positive rates of urban students showed a decreasing trend during 2004—2007,the rates were 9.31%,8.08%,6.74% and 5.24%,respectively(P0.05).There were 155 cases(8.4%)with increased ALT among 1754 HBsAg positive students.Conclusion The total positive rate of HBsAg among high school graduates in Jingjiang city from 2004—2007 was 8.36%.The HBsAg positive rate of male students was higher than that of female.The HBsAg positive rate of rural students was higher than that of urban students.8.4% students were found ALT abnormal.We should intensify Hepatitis B vaccine in time to prevent the spreading of HBV.

Objective: To study the mandibular bilateral sagittal split ramus osteotomy (BSSRO) with bicortical screws rigid internal fixation(RIF) with the three-dimensional finite element method, and supply directions for clinic practice.Methods:CT scanned technology and the finite element software (Ansys) were used to establish the three-dimensional finite element model of BSSRO with bicortical screws RIF. The stress distribution of the mandible and the RIF and the displacement of split mandible were calculated under three kind of occlusion situation.Results:Under the same kind of occlusion situation, the stress and displacement of the split mandible with single upper screws fixation was higher than that with the reverse "L" screws fixation, the stress and displacement of the split mandible with 2.0 mm diameter screws fixation was higher than that with 2.7 mm diameter screws fixation. With the same kind of fixation method, the stress and the displacemen of the mandible under the incisor occlusion was the highest.Conclusion:The fixation distance, position, distribution angle of the bicortical screws all have effects on the fixation stability. The patient should avoid the incisor occlusion after the surgery.

Whether the sentinel lymph node (SLN) metastasis has important clinical significance for the therapy and prognosis of tumor. Sentinel lymph node biopsy (SLNB) has became the most accurate clinical method to confirm the status of sentinel lymph node. And the key of the success of SLNB is the localization of SLN. The methods used to locate SLN mainly are blue dye tracer method, radionuclide tracer technique, blue dye tracer method combined with radionuclide tracer technique, indirect lymphography, NIR imaging, and photoacoustic imaging. This article demonstrates the principle, application method and contrast agents of the indirect lymphography and the application in head and neck tumor.

Purpose To investigate the protein expression of breast cancer susceptibility gene (BRCA1) in triple negative breast canc-er ( TNBC) and to analyze the prognostic impact on outcome of TNBC by BRCA1 protein. Methods The expression of BRCA1 and p53 in 95 cases TNBCs was detected by immunohistochemistry. The correlation analysis and evaluation of prognosis were conducted in consideration of patients clinical and pathological characteristics. Results The positive rate of BRCA1 protein expression in TNBCs was 31. 6%. Compared with BRCA1 negative expression, those patients with BRCA1 positive expression were associated with younger age (P=0. 047) and higher expression of p53 (P=0. 001). There was no significant difference in outcome between BRCA1 positive and negative expression (HR=1. 10,95%CI=0. 552~2. 235, P=0. 769). Conclusion The expression of BRCA1 protein may have no impact on the outcome of TNBC. There is possible correlationship between p53 pathway and BRCA1 in inhibiting tumor growth.

The diagnostic value of glutamic acid decarboxylase antibody (GAD 65-Ab) was more valuable than islet cell antibody (ICA) in type 1 diabetes mellitus by receiver-operating characteristic (ROC) curves; likelihood ratios of different regions of GAD 65-Ab and ICA could reflect the probability of type 1 diabetes mellitus.

OBJECTIVE:To provide suggestions for the improvement of curriculum system of Pharmacy Administration(Ph.A).METHODS:The basic information was collected by searching official website and the websites of universities and colleges,and the detailed data were collected through questionnaire survey.RESULTS:In the 111 universities and colleges investigated,a total of 51 curriculums(or 399 courses) related to Ph.A were set up.The main curriculums are pharmacy administration(210 courses),pharmaceutical marketing(61 courses),pharmacy laws and regulations(26 courses).In different universities and colleges,the credit hours,semester and property of Ph.A curriculums are different.CONCLUSIONS:The system of Ph.A curriculums has become more and more comprehensive,and the setup of each course suits the need of social needs.But the setup of curriculums of Ph.A in each university or college was far from systematical,and its structure remained to be optimized,and the structure of the teaching materials of Ph.A should be strengthened.
