Objective To observe the effects of wogonin on lipopolysaccharide(LPS-induced) proinflammatory cytokine production in activated microglia.Methods By using LPS-induced microglia activation model,nitric oxide(NO),tumor necrosis factor-alpha(TNF-?) and interleukin-6(IL-6) secreted by extracellular fluid were measured by ELISA.Results Microglia markedly produced NO,TNF-? and IL-6 in response to LPS.Wogonin,administered at 20-30 ?mol/L,significantly reduced the production of NO,TNF-? and IL-6 in microglia.Conclusion Wogonin has an inhibitory effect on the production of proinflammatory cytokines.

Objective To understand the pollution status of indoor volatile organic compounds(VOCs) and to provide evidence for preventing the adverse effects of them on resident health.Methods According to the different times of the house decoration, 53 residents were randomly selected from a district of Dalian.Air was sampled in the bedrooms, the kitchens and the outdoors for 24 h by sampling tubes which were activated by activated carbon and the concentrations of VOCs were analyzed by GC-MS/ SIM.Results The concentrations of VOCs indoor were higher at the half year after decoration.The concentrations of methyl isobuthyl ketone, butyl acetate, 1, 2-dichloroethane, 1, 1, 1-trichlo-roethane, tetrachlorocarbon, hexane and buthanol were 0.60, 9.15, 3.10, 1.00, 1.67, 1.90 and 14.50 ?g/m3 in the bedrooms;they were 0.60, 8.10, 3.95, 1.74, 0.85, 1.87 and 12.45 ?g/m3 in the kitchens.The concentrations of VOCs indoor were still higher than those of outside atmosphere(P

Higher education of South Korea's traditional medicine,based on the practical situation,has found a characteristic way of descending its traditional medicine,laid a solid foundation for the development of South Korea's traditional medicine.The authors introduced their admission mode,academic settings,construction of and teaching staff,and put forward some enliightenments on it so as to push the progress of our Chinese medicine.

Objective To investigate effects of different concentrations of dexmedetomidine on onset time and clinical time-effect of rocuronium in the processes of the total intravenous anesthesia.Methods Sixty patients with elective anesthesia breast modified radical mastectomy,aged 26 to 55 years,were randomly divided into four groups of 15 patients.Group A (control group):uniform within 10 min before induction of anesthesia saline infusion (NS ; 0.25 ml/kg) ; group B:dexmedetomidine given initial dose 0.3 μg/kg uniform within 10 min before induction of anesthesia infusion finished,anesthesia period 0.3 μg/(g · h) continuous infusion until the end of surgery; group C:dexmedetomidine given initial dose 0.6 μg/kg uniform within 10 min before anesthesia infusion finished,during anesthesia with continuous infusion 0.6 μg/'(kg · h) until the end of surgery ; and group D:dexmedetomidine given initial dose 1 μg/kg uniform within 10 min before anesthesia infusion finished,during anesthesia to 1 μg/(kg · h) continuous infusion to the end of surgery.Patients after the burglary were under multi-monitor vital signs monitoring blood pressure (BP),heart rate (HR),oxygen saturation (SPO2),electrocardiogram (ECG),and after intubation monitoring end-tidal carbon dioxide (EtCO2),recording time T0 and T25.Results No significant difference was found at the T0 time in each group.However,the T25 time (48 ± 6) min in group C and (51 ±6) min in group D was significant longer than that (40 ±6)min in group A (P ＜0.05).The mean artery pressure(MAP) of group C and D [(88.76 ± 7.06)mmHg,(87.89 ± 6.95)mmHg] were significantly lower than group A after dexmedetomidine infusion 5 min later(P ＜ 0.05); The HR of groups B and C [(60.80 ± 7.11)bpm,(63.31 ± 5.78)bpm] were significantly lower than group A before induction (P ＜ 0.05).The HR of group D was significantly lower than group A before induction and after infusion 5 and 30 min later[(66.40 ± 9.49) bpm,(60.52 ± 7.45) bpm,(61.32 ± 7.11) bpm,P ＜ 0.05].Conclusions Under the status of total intravenous anesthesia,different concentrations of dexmedetomidine did not affect the onset time of rocuronium,but dexmedetomidine given up to a certain concentration could enhance the clinical time-effect of rocuronium.

ObjectiveTo observe the effect of integrated traditional Chinese medicine therapy on diabetic peripheral neuropathy.Methods22 patients with diabetic peripheral neuropathy were as the group of integrated traditional Chinese medicine therapy ,who received Chinese herbal medicine treatment(orally),acupuncture,etc. Other 20 cases were as the control group,disease natural course. The effect of two groups were compared with the means.ResultsThe patients in group of integrated traditional Chinese medicine therapy got obviously better results than that of the control group(P<0.05).ConclusionThe integrated traditional Chinese medicine therapy is effective on diabetic peripheral neuropathy.

OBJECTIVEThe effect of vascular endothelial growth factor(165) (VEGF(165)) on intracellular free magnesium ([Mg(2+)](i)) and the relationship between Mg(2+) and angiogenesis in human umbilical vein endothelial cells (HUVECs) were investigated in this study.

METHODS[Mg(2+)](i) in HUVECs loaded with fluorescent magnesium indicator mag-fura-2 were quantitatively detected with the use of intracellular cation measurement system. HUVECs were obtained from normal fetus and cultured in M199 with 0.2 fetal bovine serum. The angiogenesis effects of VEGF(165) were observed in presence of 0 mmol/L, 1 mmol/L or 2 mmol/L of extracellular Mg(2+).

RESULTSVEGF(165) significantly increased [Mg(2+)](i) in a dose-dependent manner independent of extracellular Mg(2+), Na(+) and Ca(2+) and this effect could be blocked by pretreatment with VEGF(165) receptor-2 (KDR) inhibitor (SU1498). The angiogenesis induced by VEGF(165) was significantly inhibited cells with 0 mmol/L extracellular Mg(2+), the angiogenesis effects of VEGF(165) were similar in cells with 1 mmol/L and 2 mmol/L extracellular Mg(2+) and these effects could be blocked by SU1498.

CONCLUSIONSThese results suggest that the [Mg(2+)](i) increase induced by VEGF(165) originates from intracellular Mg(2+) pools and promotes angiogenesis via KDR-dependent signaling pathways.
