Objective:To explore the role of MVD, bFGF and VEGF in OMFS and the relationship between them. Methods: Immunochemistry streptavidin peroxidase method was used to detect the MVD and the bFGF, VEGF expressions in 57 cases of OMFS samples. Results: MVD, bFGF and VEGF expressions were different between OMFS and benign. The close correlations were found among the expressions of VEGF, bFGF and MVD. Conclusion: The expressions of VEGF and bFGF are associated with MVD which indicated that VEGF and bFGF may play important roles in angiogenesis.

The vectors play an important role in gene therapy by transporting the therapy genes into target tumor cells. At present there are mainly two kinds of gene vectors, including biological and non-biological vectors. Biological vectors, including virus, bacteria and stem cells, have good target activity and can efficiently delivery the genes into target tumor cells, but have potential genetic hazards.However, non-biological vectors, including liposomes and nanoparticles, can be simplely prepared with high genetic safety, but they can not transport the genes efficiently. Therefore, establishing safe and effective malignant glioma gene treatment system and finding gene vectors with good target activity become the research focus.

Objective:To study the effect of interleukin-11(IL-11),ciliary neurotropic factor (CNTF) and transforming growth factor-β (TGF-β) on the hGH gene promoter activity in rat pituitary MtT/S cells and the interaction with pituitary-specific transcription factor Pit-1.Methods:Stable transformed MtT/S cell line which contains hGH gene promoter -484-30 bp and luciferase reporter gene firstly established,then the concentration of GH in the medium and lysate of MtT/S cells and luciferase activities in MtT/S cells were measured after treatment these cells with the above cytokines,the effects of cytokines on secretion and synthesis of GH,and the promoter activity of the hGH gene were observed.Results:The results showed that IL-11(20 nmol/L),CNTF(10 nmol/L) and TGF-β(5 nmol/L) regulated secretion and synthesis of GH,and the luciferase expression in stable transformed MtT/S cells.IL-11 and CNTF had the stimulatory effect,whereas TGF-β had the inhibitory effect.Neither overexpression of Pit-1 nor inhibiting Pit-1 expression affected the regulatory role of these cytokines.Conclusion:IL-11,CNTF and TGF-β regulate the GH production in pituitary MtT/S cell line by regulating the hGH gene promoter activity.Pit-1 may not be involved in these actions.

Stromal preadipocytes from human omental adipose tissues were isolated with enzyme-digesting method,and cultured for inducing differentiation.Preadipocyte factor-1 was abundant during preadipoeyte stage,whereas lipoprotein lipase and PPARγ2 mRNA were rapidly up-regulated at early stage of differentiation and CCAAT/enhancer binding protein expression was increased rather late.In addition,resistin expression and secretion was primarily detectable in preadipocytes,leptin was gradually increased during adipogenesis,whereas adiponectin appeared specifically in mature adipocytes.Insulin-like growth factor-Ⅰ secretion was remarkably detected in both preadipocytes and mature adipocytes.

This study was aimed to evaluate the clinical effect of 66 yin-deficiency acne cases treated with body constitution adjustment using acupuncture and moxibustion. In this research, 66 acne patients with the body con-stitution of yin-deficiency were selected . These patients were randomly divided into two groups ( 33 every group ) . The acupuncture treatment group was treated by acupuncture and local treatment. And moxibustion treatment group was treated by indirect moxibustion and local treatment. The treatment was given twice a week. And the improvement condition of acne skin lesions and yin-deficiency body constitution were evaluated after 12-week treatment. The results showed that certain curative effects were received in both groups. However, the moxibustion treatment group had higher curative effect compared with the acupuncture treatment group. There were significant statistical differences between two groups ( P < 0 . 05 ) , which meant moxibustion with local treatment had a higher curative effect than acupuncture with local treatment to acne. In the aspect of skin lesion improvement, according to the statistics, the moxibustion treatment group were statistically significant compared with acupuncture group (P< 0.05), which meant more obvious improvement of skin in the moxibustion treatment group. In the aspect of body constitution, the body constitution scores in both groups were significantly declined and the moxibustion treatment group was more obvious. There was statistical significance between two groups (P < 0.05), which meant patients in the moxibustion treatment group obtained a more obvious body constitution improvement. After the treatment, follow-up was given to all patients for 4 weeks. The results showed that both the acne skin lesion con-dition and yin-deficiency body constitution score were decreased and not achieve the recurrence diagnostic stan-dard. It showed that acupuncture and moxibustion are able to activate the self-regulation and disease resistibility of the body. It was concluded that acupuncture and moxibustion not only improve skin lesion of acne patients with the body constitution of yin-deficiency with inner heat , but also regulate yin-deficiency body constitution . Moxibustion had higher efficacy in the treatment of yin-deficiency with inner heat acne than acupuncture.
