Objective To evaluate the killing effects of oxymatrine(OM) on human colon cancer cell line SW1116 and the mechanism of its anti-neoplastic effect. Methods Methyl thiazolyl tetrazolium analysis, flow cytometry , polymerase chain reaction(PCR)-enzyme linked immunosorbent assay (ELISA) and RT-PCR were used to detect the killing effects of OM and its influence on cell cycle dis- tribution , telomerase activity, expressions of human telomerase reverse transcriptase (hTERT), c-myc ,p53 and mad1 genes in SW1116 cells. Results OM exhibited dose-dependent killing effects on SW1116 cells and induced the increase of G1/G0-phase cells and decrease of S-phase cells. It was found that OM could supress the telomerase activity of SW1116 cells, and the effects were dose- and time-dependent. After OM administration, the expression of hTERT gene in SW1116 cells was decreased, those of p53 and mad1 genes were increased, and the expression of c-myc gene had no marked changes. Conclusions OM has dose-dependent killing effects on SW1116 cells.The anti-neoplastic activity of OM might be due to the inhibition of telomerase activity by means of its influence on hTERT and the up-stream regulation genes.

Objective To establish a cell line with overexpression of rat serotonin1A receptor (5-HT1AR).Methods Human neuroblastoma cells-SH-SY5Y were donated by cancer institute attached to the 4 th Affiliated Hospital, Hebei Medical University. Total RNA was extracted from brain tissues of male SD rats and rat 5-HT1A R was obtained by RT-PCR. Plasmid pc-DNA3. 1/hisC containing the rat 5-HT1AR (pc-DNA3.1/hisC-Rat-5-HT1AR)was constructed and transfected into SH-SY5Y cells. The transfected cells were isolated by G418 selection and SH-SY5Y-Rat-5-HT1A R cells were obtained. Expression of 5-HT1A R was detected by Western blot analysis. Cell viability was evaluated by MTT assay. SH-SY5Y-Rat-5-HT1AR cells were further observed for 5-HT1AR by immuno-fluorescence staining. Results Plasmid pc-DNA3. 1/hisC-Rat-5-HT1AR was successfully constructed by linking Rat-5-HT1A R with pc-DNA3.1/hisC and transfected into SH-SY5Y. The SH-SY5Y-Rat-5-HT1A R cells were more slender than SH-SY5Y cells with less and longer processes. MTT showed that the viability of SH-SY5Y-Rat-5-HT1A R cells was much lower than SH-SY5Y. Rat 5-HT1A R was expressed efficiently on the membrane of SH-SY5Y-Rat-5-HT1A R cells. Conclusion A cell line with overexpress of rat 5-HT1A R is successfully established.

Objective To establish a reversed-phase high performance liquid chromatograph ( RP-HPLC ) method for determination of equilibrium solubility and oil/water partition coeficient of phloridzin in different solvents. Methods A RP-HPLC method was established to detect the concentration of phloridzin in water and different organic solvents. The partition coefficients in the n-octanol-water/buffer solution systems of phloridzin were determined by shaking flask method. The Inertsil ODS-3 (4.6 mm×150 mm, 5μm) column was used and the detection wavelength was 284 nm.The flow rate was 1.0 mL??min-1, and acetonitrile-0.05% phosphoric acid(30??70)was used as mobile phase. Results The equilibrium solubility of phloridzin was 2.07 mg??mL-1 in water and 838.63 mg??mL-1 in methanol at 25 ℃.A good linear relationship of phloridzin was obtained within the range of 0.054 9-1.098 0 μg.The regression equation was Y=2 152.9X+7.26 (r=0.999 9).The solubility values of phloridzin were higher in ethanol and propylene glycol than in other solvents. Conclusion RP-HPLC method is simple, quick and accurate for the determination of phloridzin.Phloridzin was almost insoluble in petroleum ether and poorly soluble in water.The equilibrium solubility is higher in methanol than in other solvents. The apparent distribution coefficient of phloridzin varies significantly with pH under the alkaline conditions but less in the acidic solution.

OBJECTIVETo explore the impacts on the fine movement of upper extremity with flaccid paralysis in stroke treated with acupuncture and motor imagery.

METHODSSixty-two cases of flaccid paralysis of upper extremity in stroke were randomized into an observation group (30 cases) and a control group (32 cases). In the control group, the conventional western medication and the passive movement of the extremity were applied. Additionally, the penetrating needling technique was used at the head points [penetrating needling from Baihui (GV 20) to Taiyang (EX-HN 5)] and the local affected extremity [penetrating needling from Jianyu (LI 15) to Binao (LI1 14), from Quchi (LI 11) to Shaohai (HT 3), from Waiguan (TE 5) to Neiguan (PC 6), etc]. The needles were retained for 30 min. In the observation group, on the basic treatment as the control group, during the needle retaining, the motor imagery therapy was supplemented. The treatment was given once a day, 5 treatments a week, for 4 weeks totally in the either group. The scores in the action research arm test (ARAT) and the modified Fugl-Meyer assessment (FMA) were recorded at the moment of enrollment, in 2 and 4 weeks of treatment, in the 6th and 8th weeks, as well as after 90 days separately.

RESULTS(1) ARAT score: since the 2nd week, ARAT scores in the observation group were all improved significantly as compared with those in the control group at the each time points (all P<0. 05). In the observation group, the scores were improved significantly in the pair comparison at the time points (all P<0. 05). In the control group, the score in the 2nd week was not different significantly as compared with that before treatment (P>0. 05), but the scores at the rest time points were improved significantly in the pair comparison (all P<0. 05); (2) FMA score: in the 2nd week and on the 90th day, FMA score in the observation group was higher significantly than those in the control group (both P < 0. 05). In the observation group, the scores were all improved significantly in the pair comparison at the time points (all P<0. 05). In the control group, except that in comparison between the 90th day and the 8th week (P>0. 05), the results were all P<0. 05 at the rest time points.

CONCLUSIONThe early intervention of the combined therapy of acupuncture and motor imagery effectively promotes the recovery of the coordination function and the fine movement of upper extremity, especially the improvements of the fine movement in stroke at flaccid paralysis stage. The efficacy is better than the single acupuncture treatment.
