ABSTRACT

Objective To study the mRNA expressions of various CD97 isoforms in colorectal carcinoma tissues and their clinical significances. Methods A total of 50 colon cancer patients in the First Affiliated Hospital of Wenzhou Medical University from December 2013 to May 2014 and human colon cancer cell lines SW480 and SW620 were enrolled. The real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the mRNA expressions of CD97 human epidermal growth factor (EGF) (1, 2, 5), CD97EGF (1, 2, 3, 5) and CD97EGF (1, 2, 3, 4, 5) in colon cancer tissues, adjacent tissues, normal colon tissues, SW480 cells and SW620 cells. The relationship between the mRNA expression of CD97EGF (1, 2, 5) and the clinicopathological factors was analyzed. Results Compared with those low expressions in adjacent tissues and normal tissues, the mRNA expressions of CD97 isoforms CD97EGF (1, 2, 5), CD97EGF (1, 2, 3, 5) and CD97EGF (1, 2, 3, 4, 5) in cancer tissues were highest, and the differences were statistically significant (0.71±0.20 vs. 0.40±0.09 vs. 0.35±0.07, F=107.642, P<0.01;0.45±0.11 vs. 0.26±0.05 vs. 0.27±0.06, F=94.231, P< 0.01; 0.41±0.10 vs. 0.21±0.05 vs. 0.19±0.03, F= 165.672, P< 0.01). In addition, the mRNA expression of CD97EGF (1, 2, 5) in colon cancer patients was associated with tumor infiltration depth (T1-T2 and T3-T4), clinical stages (Ⅰ-Ⅱ and Ⅲ-Ⅳ), and the differences were statistically significant (t= -2.582, P= 0.013; t= -5.062, P< 0.01). The mRNA expression of CD97EGF (1, 2, 5) in SW620 cells was higher than that in SW480 cells. Conclusions CD97 isoforms are highly expressed in colon cancer tissues, and CD97EGF (1, 2, 5) may play an important role in the development and invasion of colon cancer. The CD97 isoforms may be new markers in the treatment of colon cancer.

ABSTRACT

Objective To understand the correct sexual health knowledge and source of sexual information among college students in Kunming, and provide the practical suggestions for students' sexual education. Methods A self-administered questionnaire survey was conducted among 950 students chosen from 5 universities in Kunming by cluster multistage sampling. Results The college students' health knowledge accuracy has certain significant differences between men and women, living urban and rural, inside and outside the province, and the Han and other nationalities. The most conversation partner discussing sex for the first time is their companion. Students get sex knowledge most in junior high school, and the school is the most important way to get these knowledge. Conclusion Sexual health knowledge education should be balanced between boys and girls, rural area students and minority students' knowledge of sexual health should be strengthened, and make them have a correct understanding onsex. In addition, strengthen the familysex knowledgeis also important.

ABSTRACT

Objective To investigate the suicide behavior among middle school students in Kunming city and its relationship with family factors, and provide a theoretical basis for prevention and control of juvenile suicide behavior. Methods 1 164 junior to senior students in 5 middle schools in Kunming were investigated by anonymous self-administered questionnaire investigation, and the collected data were statistically analysed by using SPSS software. Results The total effective number of students was 1 163, including 548 boys, accounting for 47.1%, and 615 girls, accounting for 52.8%, with age of 11 and 18 years (15.17 ± 1.838) .Among them, 153 people considered suicide, accounting for 13.1%of the proportion. Family factors of suicide analysis found that family type, education level of the parents and the family economic situation had influences on the suicide behavior among middle school students. Conclusions The suicide behavior is more common in middle school students,and is influenced by the family factors including family type,cultural degree of parents and etc.,so we should strengthen the comprehensive intervention measures to prevent the occurrence of suicide behavior based on the influencing factors.
