The present study aimed to investigate the effects of basic fibroblast growth factor (bFGF) on the expressions of angioge-nesis-related genes in a mouse brain microvascular endothelial cell line, namely bEnd.3, using cDNA microarray. The effects of bFGF (10 ng/ml) on mRNA and protein expressions of cyclooxygenase-2 (COX-2), an angiogenesis bystander molecule, were further investigated. cDNA microarray was employed to study the effects of bFGF on the expressions of angiogenic genes in a high throughput pattern. RT-PCR was used to study the effect of bFGF on COX-2 mRNA expression. Western blot and immunocytochemistry were utilized to study the effect of bFGF on COX-2 protein expression. The results showed that, 2 h after bFGF treatment, pro-angiogenic genes (Adamts1, MMP-9, Ang-1, PDGF B, G-CSF, FGF16, IGF-1, etc.) were significantly upregulated, whereas anti-angiogenic genes (TIMP-2, TSP-3, etc.) were significantly downregulated. The bystander molecule in angiogenic pathway COX-2 mRNA and protein expressions were significantly upregulated after bFGF treatment. It is suggested that triggering angiogensis switch through upregulating pro-angiogenic gene and downregulating anti-angiogenic gene expression is one of the major mechanisms of bFGF-induced angiogenesis. The expression change of COX-2, as a bystander molecule, was observed after bFGF treatment in bEnd.3 cells and the significance was discussed.

OBJECTIVETo investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.

METHODSFrom December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.

RESULTSA total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.

CONCLUSIONNetwork education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.

OBJECTIVE Neuroinflammation plays a critical role in neurodegenerative disorders, although the inflammation may not the initiating factor. Parkinson disease (PD) is characterized patho?logically by the accumulation of alpha synuclein (α-syn) and the loss of the dopamine (DA) neurons in the substantia nigra (SN), which has been reported to be induced by the stereotaxic injection of lipopolysaccharide (LPS) to the SN region in rodents. This study is to investigate the therapeutic benefit of the inhibition of miR-873 in PD. METHODS Rats received the right-unilaterally injection with concentrated LV-sponge or LV-EGFP 3 d before LPS treatment, 7 or 14 d after LPS treatment. The animals were tested for rotational behavior with the dopaminergic agonist apomorphine dissolved in sterile saline at 21 d after LPS injection. The regulation of miR-873 on the genes related with cholesterol transport and inflammation was assayed in SH-SY5Y cells and U251 cells. RESULTS TLR4-MyD88 signaling pathway was involved the regulation of miR-873 by LPS. The luciferase assay showed that HMGCR, ABCA1 and A20 were down- stream genes of miR- 873. The transfection of miR- 873 decreased the cholesterol levels in cell membrane, but increased in lysosome in SH-SY5Y cells. Compared with the control SH-SY5Y cells, cholesterol levels were higher in lysosome with α-synuclein overexpression or LPS treatment. The transfection of miR-873 increased the α-syn levels in lysosome in cells with α-synuclein overexpression. The loss of dopaminergic neuorns induced by LPS was significantly respectively decreased by 22.8%, 35.6% and 57% after the inhibition of miR-873 at 3 d before LPS treatment, 7 or 14 d after LPS treatment. Compared with LPS-treated group, the number of the rotation of rats was decreased by 60.4%, 33.5% and 13.2% after the inhibition of miR-873 at 3 d before LPS treatment, 7 or 14 d after LPS treatment. The inhibition of miR-873 significantly decreased accumulation of α-syn. The mRNA levels of HMGCR, ABCA1 and A20 in SN were decreased by LPS treatment, which was attenuated by the injection of LV- sponge. CONCLUSION The selective regulation of miR- 873 can protect the dopaminergic neurons from the LPS-induced damage. The inhibition of miR-873 can attenuate the relocation of cholesterol in lysosome and the accumulation of α-syn in neurons induced by LPS via the regulation of HMGCR, ABCA1 and A20.
