0.05). However, the 5-year local control rate appeared significantly different in three groups (?~2=7.239, P0.05). The 1-,3-,and 5-year disease-free survival rate among three groups were significantly different in the three groups (79.1%, 41.9% and 35.6% for CFR group, 85.7%, 57.1% and 38.1% for FHR group, and 95.4%, 62.8% and 58.1% for LAHR group) (?~2=6.60,P0.05). The incidence of loss of hearing, the radiation-induced temporomandibular joint lesion, and the radiation-induced brain injury was 31.3%, 41.9% and 9.3% in CFR group, and 25.0%, 35.7% and 7.1% in FRH group, and 22.7%, 35.7% and 7.0% in LAHR group, respectively. Conclusion A better 5-year local control rate and disease-free survival rate were achieved in patients in LAHR and FHR groups than those in CFR group. There are no differences in the incidence of late complications and overall survival rate among three groups.

Aim To study effects of grape seed proanthocyanidin (GSP) on learning and memory in mice. Methods After po GSP 10,20,40 mg?kg -1 respectively and contemporaneously sc D-galactose 1.25 g?kg -1 for 6 weeks, step down test and Y-type electric maze were used to examine the efficacy of GSE on learning and memory of mice first. Then lipoperoxide(LPO) level in blood and brain of these mice was measured. After po GSP 10,20,40 mg?kg -1 respectively for 2 weeks, the ability of learning and memory was measured by Morris Water Maze task. Results GSP significantly prolonged step-down latency in the mice and decreased number of errors in 5 minutes in step down test; and significantly decreased number of errors of these mice in Y-type electric maze test. LPO level in blood and brain of these mice was lower than that of model group. GSP also increased crossing platform times(CPT) and crossing platform percentages(CPP) in normal mice rested for 30 days in morris water maze test. Conclusion GSP can elevate the ability of learning and memory in mice treated with D-galactose, also improve memory retrieval at the spatial probe trials in normal mice. Mechanisms of these actions may probably be attributable antioxidative activity of GSP.

Objective To evaluate the effects of low molecular weight heparin(LMWH)and heparin-binding epidermal growth factor(HB-EGF)on the biological function of human trophoblast in first trimester.Methods From Feb.2011 to Nov.2011,the trophoblast isolated from human first trimester chorionic villi was cultured in vitro.Based on variation of LMWH concentration,the trophoblast was classified into 0.025 U/ml group,0.25 U/ml group,2.5 U/ml group,25 U/ml group and 250 U/ml group.In the mean time,based on treatment of heparin,the trophoblast was classified into LMWH group (0.25 U/ml),HB-EGF group(10 μg/L),combination group(LMWH at 0.25 U/ml + HB-EGF at 10 μg/L)and add with DMEM as control group.Cell prolferation was assessed by the methyl thiazolyl tetrazolium(MTY)test,which was showed with the mean absorbance as A value.Cell invasion was measured by transwell,which counted the number of cells migrated to the superficies inferia of filter membrane.Cell differentiation was assessed by the concentration of hCG secretion.Results Compared with control group,the trophoblast proliferation and invasion treated by LMWH at 0.025 U/ml did not show significant difference (P ＞ 0.05).When treated by LWMH at 0.25 U/ml and 2.5 U/ml,trophoblast proliferation and invasion was increased significantly(P ＜ 0.05).When LMWH at 25 U/ml and 250 U/ml,it could inhibit trophoblast proliferation and invasion(P ＜ 0.05).When compared with A value of 0.44 ± 0.04 in control group,the increased A value were 0.51 ± 0.05 in LMWH group,0.56 ± 0.04 in HB-EGF group and 0.69 ± 0.06 in combination group(P ＜ 0.05).In the transwell test,the cell number were 511 ± 78 in LMWH group,669 ± 67 in HB-EGF group and 872±64 in combination group,which were significantly higher than 405 ± 67 in control group(P ＜ 0.05),respectively.And the hCG concentration were(7143 ± 649)U/L in LMWH group,(11 762 ± 1059)U/L in HB-EGF group and(11 015 ± 1084)U/L in combination group,which showed statistical difference with(8182 ± 666)U/L in control group(P ＜ 0.05).Conclusion LMWH could modulate trophoblast proliferation,invasion,and differentiation.HB-EGF is one of important factors involved in effects of LMWH on trophoblast function.

Aim To study the effects of cycle arrest and molecular mechanism in human leukemia HL-60 cells induced by diallyl disulfide ( DADS ) . Methods Cell count, colony formation in soft agar experiments and flow cytometry analysis were employed to observe the DADS-induced cell growth inhibition and the effect of cycle arrest in HL-60 cells. The expressions of Chk1/2 and its downstream element in HL-60 cells were detected by Western blot. Results Cell count revealed that population doubling time increased to 35. 03 h and 71. 82 h, respectively, from 19. 14 h in HL-60 cells treated with 60 and 120 μmol·L-1 DADS ( P<0. 05 ) . Colony formation in soft agar experiments showed that colony formation inhibition rate of HL-60 cells exposed to 30, 60, 90 and 120μmol·L-1 DADS increased to 35. 06%, 62. 10%, 93. 79% and 99. 35%, respectively ( P<0. 05 ) . Flow cytometry a-nalysis exhibited that HL-60 cells treated with 60 and 120 μmol · L-1 DADS for 24 h and 48 h arrested in G2/M phase in a concentration-and time-dependent manner ( P <0. 05 ) . Western blot disclosed that the expression of p-Chk1 increased in a time-dependent manner ( P <0. 05 ); however, Chk1, Chk2 and p-Chk2 were not changed in HL-60 cells treated with 60μmol·L-1 DADS (P >0. 05). The expression of Cdc25C, CyclinB1 and CDK1 decreased after treated with 60 μmol·L-1 DADS in a time-dependent manner ( P<0. 05 ) , but the expression of 14-3-3 protein did not change ( P>0. 05 ) . Conclusion DADS can in-hibit the proliferation of HL-60 cells, and induce G2/M arrest through Chk1/Cdc25 C/CyclinB1/CDK1 path-way.

Objective To observe the effectiveness and mechanism of Xiaoyao San (Xiaoyao Powder for Soothing Liver and Relieving Depression) in improving depression-like behavior of rats. Methods Male Wistar rats were randomized into normal group, model group, Xiaoyao San (1.9 g·kg-1·d-1) group, and fluoxetine (2 mg·kg-1·d-1) group. The rats were exposed to chronic unpredictable mild stress ( CUMS) to induce rat depression-like behavior. Field test was performed for the observation of effect of Xiaoyao San on rat depression-like behavior, Luminex liquid chip system was applied to detect the serum cytokines, and the amount and size of rat hepatic sinusoidal endothelial window were examined under electron microscope, and hepatic indoleamine 2, 3-dioxygenase ( IDO) and tryptophan 2, 3 -dioxygenaes ( TDO) expression levels were detected by immunohistochemical and Western blot methods. Results Xiaoyao San showed obvious effect on increasing sugar water consumption, the number of crossing the blocks and erection frequency in rats, decreasing serum levels of tumor necrosis factor alpha ( TNF-α) and interleukin 6 ( IL-6) , increasing the amount of hepatic sinusoidal endothelial window, promoting hepatic sinusoidal endothelial vascularization, and reducing TDO and IDO expression ( P<0.05 or P<0.01). Conclusion Xiaoyao San exerts obvious effect on improving rat depression-like behaviors, and the mechanism is probably related with the decrease of inflammatory factors, inhibition of IDO pathway, and improvement of hepatic sinusoidal endothelial function.

Objective To conduct comparative study on the analgesic and anti-inflammatory effects as well as the acute toxicity of yunaconitine and 8-deacetyl-yunaconitine isolated from the processed products of Aconiti Knsnezoffii Radix.Methods The methods of hot plate test and writhing test were used to evaluate the analgesic effect. Anti-inflammation action was observed by the models of auricle swelling caused by dimethylbenzene. LD50 was determined by the method of Bliss.Results Yunaconitine and 8-deacetyl-yunaconitine have analgesia effect on the pain caused by hot-plate, but there were no statistically significant difference. The pain caused by acetic acid had obvious analgesic action. High and low dose of yunaconitine could significantly reduce the number of mice body torsion and extend the incubation period of pain in mice. The effect of 8-deacetyl-yunaconitine was remarkable only in the high dose. Compared with solvent group, there were little differences in inhibiting effect of auricle swelling caused by dimethylbenzene, and anti-inflammatory action was not exact. The poisonousness of yunaconitine was nearly 20 times of 8-deacetyl-yunaconitine.Conclusion Yunaconitine and 8-deacetyl-yunaconitine may be the analgesic medicine for peripheral analgesic effect. The poisonousness of 8-deacetyl-yunaconitine is less than yunaconitine, the effect is remarkable to the pain caused by acetic acid, and the security is high.
