Objective To investigate the expression of Beclin1,p62 and Atg5 in serous ovarian cancer and its clinical significance.Methods The expression of Beclin1,p62 and Atg5 was detected in 50 serous ovarian cancer tissues by immunohistochemical method,and the relationship between their expression levels and the clinical parameters of serous ovarian cancer patients were analyzed.Results The expression of Beclin1 and Atg5 in serous ovarian cancer tissue was significantly lower than that in normal ovarian tissue,but p62 was significantly higher than that in normal ovarian tissue,and the difference had statistically significance (P<0.05).The expression of Beclin1 and Atg5 were correlated with degree of cell differentiation and clinical stage (P<0.05),while the expression of p62 was associated with clinical stages and lymph node metastasis (P<0.05).Conclusions The abnormal expression of Beclin1,p62,Atg5 in serous ovarian cancer,which can lead to reduced autophagy body formation and autophagy activity,may be involved in the occurrence and development of serous ovarian cancer.

Objective To study the scale and structure of health professional education in China's colleges and universities and their changes from 1998 to 2012. Method Descriptive analyses of national data were conducted, mainly including calculation of absolute numbers, average rates of change per year, and percentages. Results The number of colleges and universities involved in health professional education increased from 189 in 1998 to 590 in 2012.The number of health professional students who were enrolled by, studied in and graduated from these colleges and universities respec-tively reached 587 thousand, 2 104 thousand, and 508 thousand in 2012, with annual growth rates of about 15 percent. The proportion of diploma graduates rose from 42.9 percent in 1998 to 54.0 percent in 2012, which was bigger than those of students at other education levels. In 2012, health professional educational institutions per 10 million popu-lation in western China was less than eastern and middle China by 1.1 and 0.9, respectively. Health profes-sional graduates per 10 thousand population in western China was less than eastern and middle China by 3.3 and 1.6, respectively. Public institutions and their students respectively accounted for 78.1 percent and 85.1 percent though private institutions and their students increased more quickly than public ones. Student-faculty ratio rose from 7.1∶1 in 1998 to 20.0∶1 in 2012. Conclusion The scale of health profes-sional education has been expanding at a decreasing growth rate in China. The disciplinary composition of health professional students has some-what improved and private schools increased at a quicker rate than public ones. However, the gap in scale of education between western China and middle/eastern China has been widening. Education re-sources per student cannot keep pace with the expansion of students, which has affected education of health professionals in many aspects.
