BACKGROUND: Numerous studies have shown that nuclear factor-KB (NF-kB) was positively correlated with vascular endothelial growth factor (VEGF) in the cerebral hypoxia region. Thus, we assumed whether NF-kB in the pathway of hypoxia-inducible factor-1 α (HIF-1α) upregulating VEGF and plays a bridge effect.OBJECTIVE: To study the effects of NF-kB in HIF-1α pathway of increasing expression of VEGF using HIF-1α-modified neural stem cells (NSCs) as vectors.DESIGN, TIME AND SETTING: In vitro observation of cytology was conducted at the Neuroscience Institute, Jiamusi University from March to December 2008.MATERIALS: Wistar rats aged less than 24 hours of both genders were used.METHODS: NSCs were transfected after amplification of adenovirus vector HIF-1α (AdHIF-ia)-green fluorescent protein (GFP).Fluorescence detection was used to determine HIF-1α-GFP and blank vector Ad-GFP expression in NSCs. Protein was extracted from transfected NSCs, blank vector NSCs and normal NSCs, separately. Subsequently, NF-kB specific inhibitor pyrrolidine dithiocarbamate (PDTC) (50,150, 300 μmol/L) was added in HIF-1α-modified NSCs. Western blot analysis was used to determine changes in VEGF expression.MAIN OUTCOME MEASURES: The following parameters were measured: expression of HIF-1α, VEGF and NF-kB in NSCs in each group; VEGF expression in NSCs following treatment of NF-kB specific inhibitor.RESULTS: Gene expression was associated with MOI and transfected time following AdHIF-1α-GFP transfected with NSCs. After transfected AdHIF-1α-GFP in NSCs, HIF-1α, VEGF and NF-kB expression was positively correlated. Expression of VEGF was reduced in AdHIF-1α-GFP-modified NSCs following treatment of NF-kB inhibitor PDTC in a concentration-dependent fashion.There were significant differences in VEGF expression between each concentration group (P < 0.05-0.01).CONCLUSION: NF-kB in signaling pathway of HIF-1α-upregulated VEGF expression and played a bridging effect.

Objective To evaluate the symptom improvement of anxiolytics and antidepressant to hemifacial spasm(HFS)patients with anxiety and depression. Methods A total of 60 HFS patients with anxiety and depression were enrolled for the study and divided into experimental group and control group. Experimental group were treated with escitalopram and BTX-A ,and control group only received BTX-A. SAS and SDS were used to test all the patients before and after treatment. Results Both experimental group and control group were significantly improved after BTX-A therapy. There was no different between two groups at 1 week and 1 month,respectively. At 2 weeks and 3 months,more obvious improvement was seen in experimental group. The SAS and the SDS standard average scores of experimental group were significantly decreased compared with the control group. There was statistical significance in control group after 1 month and 3 months treatment(P<0.05),and in experimental group,the differences appeared after 2-week treatment(P<0.05). Additionally,after 1 month treatment,there were statistical differences between the two groups(P<0.05),and experimental group shown a longer effective period compared with control group. Conclusion Anxiety and depression state serves as a complication of HFS ,which is positively correlated with HFS. HFS patients with anxiety and depression benefit better from escital-opram and BTX-A combination therapy than BTX-A alone.

Objective: To analyze the expression of CMTM1-v17 in normal prostate tissue and prostate carcinoma originated cell lines, and study its impact on the transactivation of androgen receptor and the possible mechanism. Methods: The expression of CMTM1-v17 in normal prostate tissue was analyzed with immunohistochemistry method. In immounocytochemistry was used to analyze the expression of CMTM1-v17 in prostate carcinoma originated cell lines. Luciferase assay was used to study the impact of CMTM1-v17 on the transactivation of AR and its mechanism. Results: The results of immunohistochemistry showed that CMTM1-v17 was highly expressed in prostate. In prostate cancer originated cell lines, CMTM1-v17 could also be detected in prostate cancer originated cell lines PC3, Du145 and LNCaP. And the results of luciferase implied that the relative luciferase activity of the PC3 cells transfected with 1 ?g and 2 ?g pCDI-CMTM1-v17 plasmids separately were 70.8 and 34.7, compared with the control set as 100. When trichostatin A, the inhibitor for histone deacetylase, was used, the repression of androgen receptor could be recovered with trichostatin A treatment,for the relative luciferase activity of the PC3 cells transfected with 1 ?g and 2 ?g pCDI-CMTM1-v17 plasmids and treated with 100 nmol/L trichostatin A rebound to 90.9 and 86.4. Conclusion: CMTM1-v17 is highly expressed in both normal prostate and prostate carcinoma originated cell lines. It may recruit histone deacetylas to inhibit the function of androgen receptor.
