Objective To investigate the effect of early limb movement on the motor function and the activities of daily life of stroke patients. Methods Eighty two stroke patients were divided into the control group(n=40)and intervention group(n=42). The former received conventional nursing care and the latter the intervention of early limb movement and routine nursing.The two groups were compared in terms of Fugl-Meyer movement function and Barthel index. Results After 12 weeks,the scores by Fugl-Meyer motor function and by Barthel index were significantly higher than those in the control group(all P<0.01).Conclusion The intervention by early limb movement is effective for promoting the recovery of limb motor function of stroke patients as well as their ability of daily life.

AIM To study the direct effect of amiloride on recombinant human protein kinase CK2 holoenzyme and its kinetics. METHODS Recombinant human protein kinase CK2 ? and ? subunits were cloned,expressed and purified by gene engineering. The two subunits were mixed at the same molar ratio to form CK2 holoenzyme,which displayed the maximum biological activity. CK2 activity was assayed by detecting incorporation of 32 P of [? 32 P]GTP into the substrate in various conditions. RESULTS Amiloride inhibited the holoenzyme activity of recombinant human protein kinase CK2 with an IC 50 of 257 57 ?mol?L -1 . Kinetic studies of amiloride on recombinant human CK2 showed that the inhibition was competitive with GTP with the K i of 236 30 ?mol?L -1 ,and noncompetitive with casein with the K i of 163 63 ?mol?L -1 . CONCLUSION Amiloride inhibits the activity of cAMP or ATP dependent enzymes as well as the kinase with GTP as phosphate donor,and the recombinant human protein kinase CK2 may be used as a molecular target for simple screening and development of effective inhibitors of CK2.

Objective To explore the application of video-assisted thoracic surgery (VATS) in the diagnosis and treatment of mediastinal tumors. Methods Thirty-four patients with mediastinal tumors underwent VATS from June 1995 to December 2002. The patients comprised 9 men and 25 women, with a mean age 43 9 years (16～74 years). Entered into the study there were 14 cases of thymoma (9 benign thymomas and 5 malignant), 6 cases of neurogenic benign tumors, 5 bronchogenic cysts, 4 teratomas, 2 pericardial cysts and 3 other conditions (metastatic carcinoma, lymphoma and hemangioma racemosum, respectively). Maximum diameter of the tumors ranged 3 5 cm to 6 cm, mean 4 5 cm. Operations were performed under general anesthesia, double lumen endotracheal tube placement and single lung ventilation. The patients were maintained in the lateral decubitus position. Camera port was placed at the sixth or the seventh intercostals space on the midaxillary line. Sites of the other two ports depended upon the location of the tumors. Results Out of the 34 patients with mediastinal tumors, 25 patients underwent tumor removal by VATS alone and 6 patients received VATS combined with mini-thoracotomy, while the remaining 3 patients only underwent biopsy by VATS. Postoperatively, all patients recovered uneventfully, without severe complications or mortality. Conclusions VATS is the first choice for benign mediastinal tumors, typically those in the middle and posterior mediastinum.

OBJECTIVE:To study inhibitory effects of propofol on PC12 cells injury induced by glutamic acid via mitogen-acti-vated protein kinase/extra-cellular regulated kinase (MAPK/ERK) signal pathway. METHODS:PC12 cells were randomized into normal control group,model group(10 mmol/L glutamic acid),propofol low-concentrations,medium-concentrations and high-con-centrations groups(12.5,25,50 μmol/L+10 mmol/L glutamic acid). The optical density of cells,cell apoptosis,the phosphoryla-tion of ERK1/2 and the expression of c-fos,Bax,Bcl-2 were detected after treated with relevant medicine for 48 h. RESULTS:Compared with normal control group,optical density of cells,the phosphorylation of ERK1/2 and Bcl-2 decreased in model group (P<0.01);apoptotic rate,the expression of c-fos and Bax increased (P<0.01). Compared with model group,optical density of cells,the expression of Bcl-2 and the phosphorylation of ERK1/2 increased in propofol group (P<0.01);apoptosis rate,the ex-pression of c-fos and Bax decreased (P<0.05 or P<0.01). There were statistical significant between the different concentrations (P<0.01). CONCLUSIONS:Propofol can inhibit the apoptosis of PC12 cells induced by glutamic acid,which is associated with the up-regulation of ERK1/2 phosphorylation.

Aim To study the growth inhibitory effect of the conjugate ( ovarian cancer specific targeting peptide and cisplatin, OSTP-DDP ) that targeting ovarian cancer cells A2780. Methods Using chemical method to syn-thesize OSTP-DDP, ovarian cancer cells A2780 were cul-tured in vitro, using CCK-8 method ( Cell Counting Kit-8) to detect the growth inhibitory effect of ovarian cancer A2780 cells, which were disposed by OSTP-DDP and DDP. Annexin V-FITC was used to detect the cycle and apoptosis effect of ovarian cancer A2780 cells which were disposed by OSTP-DDP and DDP. Results According to the mass spectrometry and the high performance liquid chromatography ( HPLC ) analysis, OSTP-DDP was proved to synthesize successfully. CCK-8 assay showed that both OSTP-DDP and DDP could play the growth in-hibitory effect and showed a concentration-dependent manner when cells were treated in different concentrations (10,20,40,80,160,320μmol·L-1 ) respectively after 24 h, 48 h, 72 h. And the effect of OSTP-DDP was stronger than DDP (P<0. 05), indicated OSTP-DDP had targeted cytostatic effect. The result of the flow cytometry showed that cell cycle was mostly arrested in G1 phase after 72h treated by OSTP-DDP and DDP, the inhibitory effect of OSTP-DDP was stronger than DDP (P<0. 05). The apop-tosis effect of OSTP-DDP was stronger than DDP ( P <0. 01),suggested that OSTP-DDP had a stronger targeting apoptosis-inducing effect. Conclusion OSTP-DDP has the targeting growth inhibitory effect on the ovarian cancer cell A2780, OSTP as a chemotherapeutic drug targeting vector has a great prospect to treat ovarian cancer.

Objective To observe the efficacy of percutaneous vertebroplasty (PVP) combined with zoledronic acid in treatment of spinal metastatic carcinoma.Methods Fifty cases of spinal metastatic carcinoma were divided into control group and treatment group by random digits table method with 25 cases each.The control group was given zoledronic acid 4 mg,intervals of 28 d intravenous drip 1 time.The treatment group was given PVP besides zoledronic acid.The visual analog scale score,activity ability score and analgesic usage score after treatment for 3 months were observed and compared.The quality of life was evaluated and the occurrence of relapse of fracture was also recorded.Results After treatment for 3 months,the visual analog scale score,activity ability score and analgesic usage score were (2.00 ± 0.17),(2.12 ± 1.38),(1.47 ± 0.10) scores in treatment group,and (7.84 ± 0.18),(3.21 ± 0.13),(3.30 ± 0.09) scores in control group,and there were significant differences between two groups (P ＜ 0.01 or ＜ 0.05).The occurrence of relapse of fracture was 2 cases (8％,2/25) in treatment group and 9 cases (36％,9/25) in control group,and there was significant difference between two groups (P ＜ 0.05).Conclusions PVP combined with zoledronic acid in treatment of spinal metastatic carcinoma has many advantages such as small incision,short surgery time and rapid relief from pain.It can obviously improve the quality of life,and it is worthy of spreading in the clinic.

ObjectiveTo compare the clinical efficacies between bloodletting cupping plus acupuncture and acupuncture alone in treating hypertension.MethodSixty patients with primary hypertension were randomized into a treatment group and acontrol group, 30 cases in each group. The treatment group was intervened by bloodletting cupping plus acupuncture, while the controlgroup was by acupuncture. The clinical symptoms, blood pressure, and hemorheological parameters were observed before and after intervention.ResultThe clinical symptoms were improved in both groups after intervention, and the total effective rate was 76.7%in the treatment group versus 63.3% in the control group; the blood pressure dropped in both groups, and the differences were statistically significant between the two groups (P<0.05); the treatment group was superior to the control group in improving the whole blood viscosity and erythrocyte sedimentation rate(P<0.01).ConclusionBloodletting cupping is effective in treating primary hypertension; regarding the short-term therapeutic efficacy, bloodletting cupping plus acupuncture can produce a more significant effect than acupuncture alone in improving the blood pressure, whole blood viscosity, and erythrocyte sedimentation rate in primary hypertension patients.
