The vacuolated effect of Helicobacter (H. pylori) and its relationship to vacuolated cytotoxin antigen (VacA) were investigated by the method of cytotoxic test and SDS-pobyacrylamide gel electrophoresis (SDS-PAGE). Of the 62 clinical isolates, the broth culture filter (BCF) of 43 strains caused the Vero cell intracytoplasmically vacuolated. H. pylori strains were divided into H. pylori (Toxin+) group with vacuolated effect and H. pylori (Toxin-) group without vacuolated effect. The analysis of the BCF of H. pylori (Toxin+) and that of H. pylori (Toxin-) was studied by SDS-PAGE and Scan reader. A kind of protein with 87 ku molecular weight was recognized in the BCF of 30.23% (13/43) H. pylori (Toxin+) strains but in none of that of H. pylori (Toxin-) strains, the difference was statistically significant (P < 0.05). There was a significant and concordant relationship between OD of the protein band with 87 ku molecular weight and titer of vacuolated activity of H. pylori (Toxin+) (r = 0.67 and P < 0.05 by linear regression analysis). H. pylori strains were divided into H. pylori (Toxin+) group with vacuolated effect and H. pylori (Toxin-) group without vacuolated effect. The vacuolated effect of H. pylori (Toxin+) was caused by the protein with 87 ku molecular weight (VacA).

Objective To explore the value of hysteroscopy in diagnostic curettage, the incidence of complications and preventive measures in senile women. Methods One hundred and thirteen senile patients who underwent hysteroscopy from January 2002 to December 2007 were recruited in the study, and one hundred and fifty-seven non senile patients were selected as control group. All the patients were operated with diagnostic curettage and hysteroseopy. The success rate of hysteroscopy operation, the incidence of complications and control effect were recorded and compared between two groups. Results The success rate of hysteroscopy operation was 88. 5% (100/113) in the senile group and 100% (157/157) in the non senile group, and there was significant differenee(P <0. 01). The incidence of complications was higher in the senile women group than that in the non senile women group (P< 0. 01). In senile group, the accuracy of diagnostic curettage and hysteroscopy was higher than diagnostic curettage alone, and the success rate was 95.5% (64/67)in estrogen group and 69.6%(32/46) in blank control group (P<0. 01) ,which indicated that estrogen was positively related with the success rate of operation. Compared with misoprostol, estradiol-pretreatment operation was safer and had higher success rate. Conclusions It is safe and feasible to perform hysteroscopy and diagnostic curettage for older women, though it has higher incidence of complications and lower success rate compared with non senile women. Hysteroscopy and diagnostic curettage are more accurate than diagnostic curettage alone, and it is a good choice to apply estradiol before operation.

ObjectiveTo develop three animal models to mimic muscle tremors of Parkinson's disease and observe effects of Chinese herb compounds Jian-Xing on these models.MethodsPure muscle tremor mice models were developed by single intraperitoneal injection of arecoline or oxotremorine. The mitochondria damaged model was developed by intraperitoneal injection of MPTP(1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) 20mg/kg for 8 days. Duration time of tremoring was recorded. The climbing time and spontaneous movements of MPTP mice were recorded. HPLC was used to detect the content of dopamine and it's metabolites in MPTP mice.ResultsAfter injection of oxotremorine or arecoline,model mice exhibited significant tremoring, duration time of tremor of mice in Jian-Xing group shortened significantly. As to MPTP model mice, climbing time of model mice prolonged, times of spontaneous movements of model mice decreased and the content of dopamine in striaturn decreased compared with control group. Climbing time of mice in Jian-Xing group shortened, spontaneous movements increased and content of dopamine increased distinctively. ConclusionOxotremorine, arecoline and MPTP all can produce tremor animal models. Chinese herb compounds Jian-Xing can shorten the duration time of tremor.As to MPTP model, Jian-Xing can shorten the climbing time of model mice, increase the spontaneous movements and increase the content of dopamine in striaturn.

Objective To explore the effects of upper limb robot-assisted therapy on motor function and activities of daily living in con-valescent stroke patients. Methods From June to September, 2016, 12 chronic stroke patients at their first-ever stroke were enrolled and ran-domized into experimental group (n=6) and control group (n=6). Both groups received routine rehabilitation. Additional robot-assisted thera-py was provided to the experimental group, and additional repetitive movement training was provided to the control group, 20 minutes a day, five days a week for four weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Ashworth Scale (MAS) and Func-tional Independent Measure (FIM) were used to assess the motor function of the upper limbs and hands, the muscular tension of shoulder and elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FMA-UE and FIM were bet-ter in both groups (Z>2.032, P<0.05), and no significant difference was found between two groups (t<0.723, P>0.05), however, the scores were a little bit higher in the experimental group than in the control group. After treatment, for the experimental group, the MAS scores of shoulder abduction/adduction and elbow flexion/extension improved (Z>2.121, P<0.05);for the control group, the MAS scores of shoulder abduction/adduction improved (Z>2.000, P<0.05), but the MAS scores of elbow flexion/extension were not significantly different (Z<1.890,P>0.05). There was no significant difference in the MAS scores of shoulder abduction/adduction and elbow flexion/extension between two group (Z<1.734, P>0.05). The moving trail recorded by the computer, gradually became a regular pattern from the mass, saying the motor control ability became better. Conclusion Upper limb robot-assisted therapy can promote the recovery of the motor function of upper limbs and ADL in convalescent stroke patient, similar to the repetitive movement training.

OBJECTIVETo study the killing effects of the liposome-mediated thymidine kinase (TK)/ganciclovir (GCV) system on MG-63 osteosarcoma (OS) cells and its bystander effects.

METHODSLiposome-mediated TK gene transfected into MG-63 OS cells, the efficiency of transfection was analyzed by flow cytometry and observed under inverted fluorescence microscope. Non-transfected osteosarcoma MG-63 cells were divided into three groups,in the experimental group 1 transfected TK/GCV cells cultured in solutiona liquid mixture by supernatant by 1/10,1/7,1/5,1/2 ratio to original broth; in the experimental group 2 transfected cells cultured in solutiona liquid mixture of supernatant filtered through 0.22 microm filter by 1/10,1/7, 1/5, 1/2 ratio to original broth, in control group the transfection cells cultured in original culture solution. Cell growth inhibition rate and osteosarcoma cell sensitivity to TK/GCV system were measured by MTT assay in each group.

RESULTSThe TK gene was transfected into MG-63 OS cells successfully by liposome-mediated, flow cytometry instrument detection TK gene transfection cell transfection efficiency can reach 75.5%. Six days later the MTT assay showed that in the experimental group 1 inhibition rate of all concentration ratio of the mixed culture fluid were statistically significant as compared with the control group (P < 0.05), and in the experimental group 2 that of the 1/10 and 1/7 of concentration ratio of mixed culture medium was not statistically significant as compared with the control group (P > 0.05). TK gene transfected MG-63 cells increased with the the GCV concentration,the cell apoptosis rate increased.

CONCLUSIONThe experiment demonstrated that the MG-63 OS cells are sensitive to the liposome-mediated TK/GCV system and bystander effects are significant.
