Objective To investigate the roles of sphingosine kinasel (SPK1) in apoptosis,invasiveness and multidrug resistance of human hepatocellular carcinoma cell line BEL-FU.Methods BEL-FU cells were infected with adenovirus carrying SPK1wT gene and SPK1siRNA (Ad-H1-SPK1) gene.Their effects on biological characteristics of BEL-FU cells were evaluated by MTT,cellular SPK enzyme activity assay,Transwell Migration Technology and Western-blot,respectively.Results AdSPK1wT significantly increased SPK activity but SPK1siRNA(Ad-H1-SPK1) decreased SPK activity.Over expression of SPK1 suppressed the apoptosis induced by DMS(Dimethyl sphingosine,DMS) and enhanced migration of BEL-FU cells.The cells infected with SPK1 siRNA( Ad-H1-SPK1)significantly increased the apoptosis induced by DMS and inhibited the migration of human hepatocellular carcinoma cells.The expression of multidrug resistance-related protein (MRP1) of cells infected with SPK1siRNA (Ad-H1-SPK1) was suppressed significantly compared with the control group,while the expression of MRP1 infected with Ad- SPK1wT was enhanced.Conclusion SPK1 activity is closely associated with apoptosis、migration and multidrug resistance of human hepatocellular carcinoma cells,therefore,it may serve as a new target for HCC treatment.

Objective To evaluate the influence of grape seed proanthocyanidin extract (GSPE) on sunburn cell formation and p53 protein expression induced by acute ultraviolet injury. Methods Ten volunteers were enrolled in this study. The buttock region served as the exposed region. Four areas were randomized and delineated on the buttock: one area (control area) received no exposure or product, the other 3 areas were exposed to two minimal erythema doses (MED) of simulated solar radiation (SSR) for 3 days. Of the 3 exposed areas, one area (SSR) received no product before exposure, one area (SSR + Veh) was pretreated with vehicle, the third area (SSR + GSPE) with the samples of GSPE. GSPE or vehicle was applied 30 minutes before each exposure at 2 μL/cm2. Skin biopsy was performed 24 hours after the last exposure, and skin specimens were subjected to hematoxylin eosin (HE) staining and histochemical analysis for p53 protein. Results There was a statistical difference in the number of sunburn cells per high power field (×200) between SSR sites and SSR + GSPE sites (29.8±11.1 cells vs 2.2±0.2 cells, P<0.01). A significant decrease was noticed in the account of p53 protein-positive cells per high power field (×200) in SSR + GSPE sites com-pared with the SSR sites (4.6±0.7 cells vs 19.3±3.4 cells, P<0.05). Conclusion GSPE exerts a poten-tial protective effect against acute ultraviolet injury and can serve as a natural sunscreen.

Objective To investigate the characteristic of movement disorders,so as to improve their diagnosis and treatment. Methods The clini?cal data of patients with movement disorders that admitted in the dystonia and Botox outpatient department were analyzed. Results Cases of involun?tary movement were significantly more than the primary dystonia,and case of primary hemifacial spasm was dominant(163 cases,61.05%). Among the 66 cases of primary dystonia,blepharospasm was ranked the first(19 cases),the second was spasmodic torticollis(18 cases),and the third was Meige syndrome(12 cases).There was no statistical significance in the gender distribution among primary hemifacial spasm,blepharospasm,spas?modic torticollis and Meige syndrome. Instead,there was statistical significance in the treatment methods(P<0.05),and there was statistical signifi?cance in the mean treatment and onset age(P<0.05). Of the 163 cases with primary hemifacial spasm,the mean onset age was 44.22±12.22 years, and the ratio of men to women was 1∶2.4. There were statistical significances in the mean onset age and duration among the patients with different severity degrees(all P<0.05). Conclusion Primary hemifacial spasm,blepharospasm,spasmodic torticollis and Meige syndrome are the com?mon disease in outpatient department. The primary hemifacial spasm is dominant,women are more than men,and the onset age and/or duration are proportional to the severity degree.

Heat shock protein 27 ( HSP27 ) is an endogenous protein that plays an important role in a great variety of physio-logical and pathological processes. It can express a large number under body stress conditions. Recent studies have shown estro-gen upregulates the expression of HSP27 through a number of ways, playing a perfect “triple protection” role. In the early stage of atherosclerosis, estrogen induces the phosphorylation of HSP27 via PI3K/Akt signaling pathway. Phosphorylation of HSP27 can resist the injury of vascular endothelial cells( VECs) through an antioxidant and anti-apoptotic pathway as well as the inhibition of cytochrome C. In the stage of forming foam cells, estrogen induces the expression and release of HSP27 from mac-rophages by stimulating the estrogen receptor β ( ERβ) , then HSP27 inhibits the LDL uptake and the release of proinflammato-ry cytokine by binding scavenger receptor A ( SR-A) . During the proliferation and migration of vascular smooth muscle cells ( VSMCs) , estrogen induces estrogen receptor α ( ERα) and protein phosphatase 2 ( PP2A) to form a complex that enhances the activity of PP2A, then it can lead to the dephosphorylation of HSP27 and finally inhibit cells proliferation and migration. In summary, the anti-atherosclerotic effect of estrogen is closely re-lated to the role of HSP27. Given the side effects of estrogen re-placement therapy( MHT) , regulating HSP27 may provide a no-vel therapy for the prevention and treatment of cardiovascular dis-eases in menopausal women clinically.
