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.

Objective To investigate the mechanism of IL-17, the signature cytokine produced by Th17 cells, in OLP lesion. Methods 24 patients with reticular OLP, 19 patients with atrophic-erosive OLP and 13 healthy volunteers were enrolled in this study . Real-time quantitative PCR ( real-time qPCR ) was performed to analyze the expressions of the production of IL-17 and CCL20 mRNA. Results The expressions of IL-17 mRNA in reticular OLP and atrophic-erosive OLP were significant higher than that in healthy oral mucosa (P = 0.0095, P <0.0001, respectively), meanwhile, remarkable increased IL-17 expression in atrophic-erosive OLP group was found compared with reticular OLP group (P = 0.0012). Additionally, the expressions of CCL20 mRNA in reticular OLP and atrophic-erosive OLP were significant higher than that in control group (P=0.0357, P<0.0001, respectively), meanwhile, CCL20 expression in atrophic-erosive OLP was higher than that in reticular OLP. The expressions of CCL20 mRNA rises with the increased expression of IL-17, and were positive correlated with IL-17 expressions in OLP lesions (P=0.003). Conclusions IL-17 production can induce chemokine CCL20 expression in OLP lesion. The signal pathway may promote the migration and infiltration of inflammatory cells in OLP lesions.

OBJECTIVETo explore the role of Compound Danshen Injection (CDI) in regulating the expression of aquaporin 3 (AQP3) in human amnion epithelium cells (hAECs), and to study the relation between c-Jun N-terminal kinase (JNK) signal pathway and AQP3.

METHODShAECs were isolated and primarily cultured from term pregnancy with normal amniotic fluid volume and from term pregnancy with oligohydramnios, and then hAECs were further divided into four groups, i.e., the blank control group (A), the SP600125 group (B), the CDI group (C), and the SP600125 +CDI group (D). The cell viability was measured by cell counting kit-8 assay (CCK-8). The expression of total JNK, phosphorylated JNK, and AQP3 were determined by Western blot.

RESULTS(1) In hAECs with normal AFV or with oligohydramnios: There was no statistical difference in the cell viability or the expression of total JNK among the 4 groups (P > 0.05). But there was statistical difference in the expression of p-JNK (P < 0.05). Compared with A group, the expression of p-JNK was obviously down-regulated in B group, but obviously up-regulated in C group (P < 0.05). The expression of p-JNK was significantly lower in D group than in C group, but higher than that in A group or B group (P < 0.05).The AQP3 expression in the hAECs with normal amniotic fluid volume of C group and D group were higher than that in the A group (P < 0.05). However, there was no statistical difference in the AQP3 expression between C group and D group (P > 0.05). In hAECs with oligohydramnios, the expression of AQP3 obviously decreased in B group, but up-regulated in C group (both P < 0.05). The expression of AQP3 was lower in D group than in C group, but higher than in B group (P < 0.05).

CONCLUSIONCDI could regulate the AQP3 expression in hAECs with oligohydramnios via activating the JNK signal pathway.

Objective To determine the molecular mechanism of berberine (BBR) inhibiting the metastasis and invasion of nasopharyngeal carcinoma 5-8F cells, and identify whether berberine suppresses the tumor-invasive action through inhibiting Ezrin or phosphate-Ezrin. Methods The non-cytotoxic concentration of berberine was detected by MTT assay. Filopodia formation of 5-8F cells was observed by electron microscope. The invasion and motility of 5-8F cells with berberine treatment were measured with Trans-well assay. Western blot was used to investigate the Ezrin and phos-Ezrin expression in 5-8F cells treated by berberine. pcDNA3.1-Ezrin and pcDNA3.1-Ezrin M were transfected into 6-10B cells. The inhibitory effect of berberine on the motility and invasion of 6-10B-pcDNA3.1-Ezrin and 6-10B-pcDNA3.1-Ezrin M was detected, respectively. Results Berberine non-cytotoxic concentration was 0-40 μmol/L. After being treated by berberine, filopodia of 5-8F cells obviously reduced, and the permeating artificial basement membrane cells largely decreased in both time- and concentration-dependent manner. There was significant difference compared with the control group (P<0.05). Berberine suppressed the phos-Ezrin expression of 5-8F cells in both time- and concentration-dependent manner (P<0.05), but the effect of berberine was weaker on 6-10B-pcDNA3.1-Ezrin M than on 6-10B-pcDNA3.1-Ezrin. Conclusion Berberine inhibits nasopharyngeal carcinoma cell invasion through inhibiting phos-Ezrin expression and filopodia formation.
