ObjectiveTo observe and explore the effects ofJiakangning Capsules on the expression of ERK1/2 gene and proliferation of FRTL-5 by studying the effects ofJiakangning Capsules collaborated with siRNA on interfering ERK1/2 gene in FRTL-5.Methods FRTL-5 cells in good conditions were divided into control group, negative control group,Jiakangning Capsules collaborated with siRNA group, siRNA interference group, and Jiakangning Capsules group. RT-PCR was performed to detect the expression of ERK1/2 gene in mRNA levels in FRTL-5; Western blotting was performed to detect the expressions of ERK1/2 and p-ERK1/2; CCK8 method was used to detect cell proliferation.Results RT-PCR results showed that the ERK1/2 mRNA expression of the control group and negative control group were of no significant difference (P>0.05); compared with the control group, siRNA interference group andJiakangning Capsules group could inhibit ERK1/2 gene mRNA expression in FRTL-5 (P<0.01). Compared with the control group and negative control group, the ERK1/2 mRNA expression of Jiakangning Capsules collaborated with siRNA group decreased obviously (P<0.01). Compared with the control group and negative control group, the expression of p-ERK1/2, ERK1/2 ofJiakangning Capsules group, Jiakangning Capsules collaborated with siRNA group, and siRNA interference group decreased obviously (P<0.01). At the time of 24 h and 48 h after transfection, according to the results of CCK8, compared with the control group and negative control group, the cell proliferation ofJiakangning Capsules group, Jiakangning Capsules collaborated with siRNA group, and siRNA interference group was inhibited (P<0.01).Conclusion Jiakangning Capsules have blocking effect on the phosphorylation of ERK1/2. After ERK1/2 gene was silenced, the thyroid cell proliferation was inhibited. Jiakangning Capsules can collaborate with ERK1/2-siRNA to inhibit FRTL-5 cell proliferation.

Objective To investigate the effect of neuromuscular activation on patients with low back pain after lumbar vertebra fracture operation. Methods 60 low back pain patients who received lumbar vertebra fracture operation were divided into treatment group (n=30)and control group (n=30). Both groups received 20 times of frequency treatments for 4 weeks. While the treatment group received the lumbar stability treatment with neuromuscular activation, and the control group received back muscle strengthen treatment. They were assessed with visual analogue scale (VAS) for pain and Short Form of Health Survey (SF-36) before, 4 weeks and 6 months after treatment. Results The scores of VAS and SF-36 was not significantly different between 2 groups (P>0.05) before treatment, and was significantly different (P<0.05) 4 weeks after treatment and later. Both the scores of VAS and SF-36 improved in both groups after treatment (P<0.05). Conclusion Neuromuscular activation can relieve low back pain after lumbar vertebra fracture operation and improve the quality of life.

Objective: To provide an effective hGM CSF gene transferring vector mediated by gene gun and a basis for study of hGM CSF gene modified tumor cell vaccines. Method: The gastric tumor cell line (SGC) was transfected with eukarytic expression plasmid deoxyribonucleic acid containing the human granulocyte macrophage colony stimulating (hGM CSF) gene using the gene gun. The SGC cell clones (SGC GM CSF 1~5)secreting high hGM CSF level were obtained after G418 resistance selection. The hGM CSF gene had been integrated into chromatosome of SGC by the assay of RT PCR.Results: There was hGM CSF production whose lane was about 30 kD in the culture medium of SGC GM CSF by the assay of SDS PAGE and Western blot. SGC GM CSF had the ability of the high level of GM CSF for a long time(mean 247ng/(10 6 cell?24 h).Conclusion: The hGM CSF gene transferring vector mediated by gene gun was effective and safe. These results provide a basis for study of GM CSF gene therapy for cancer.

Objective To investigate the effect of isokinetic training on stiff knees after fracture arrest. Methods 38 fracture patients were divided into observation group (n=19) and control group (n=19) by the medical number. Both 2 groups received the Chinese herbs fumigation and joint mobilization. Besides, the observation group received the isokinetic training, while the control group received the instrument training. The range of motion (ROM), maximum peak torque (PT), peak torque/body weight (PT/BW), average power (AP), and hamstrings/quadriceps (H/Q) were tested before and 16 weeks after training. Results The flexion, straightness and flexion radian became significantly better after training. The flexion and the increase of the flexion radian were significantly better in observation group than in control group after training. All indexes of the isokinetic test significantly improved after training (P<0.001) except H/Q (P>0.05). ROM、PT、PT/BW and AP of the knees joint were significantly better in the observation group than in the control group (P<0.001) after training, while there was no significant difference in H/Q between 2 groups (P>0.05) after training. Conclusion Isokinetic training can promote recovery of stiff knees of femur fracture.

Objective To explore the change of Brain natriuretic peptide(BNP) and endothelin-1 (ET-1) levels in artial septal defect(ASD) patients and the relationship among BNP,ET-1 and pulmonary pressure.Methods 105 final diagnosed ASD patients were divide into non-pulmonary hypertension group (nPH group) and pulmonary hypertension group(PH group),and the PH group were divided into two subgroup:slight PH group,moderate and sever PH group.According to the altitude of habitation,105 ASD patients also were divided into 3 groups:< 2 500 m group,2 501-3 500 m group and > 3 500 m group.Plasma BNP were measured by radioimmunity method and ET-1 were measured by ELISA.The data analysis used single factor analysis and Fisher least singnificant difference t test.Results Both the plasma BNP levels (152.34 ± 40.61) pg/ml and ET-1 level (137.69 ± 37.17) pg/ml of the ASD-PH group were significantly higher than those [BNP (126.70 ± 32.27) pg/ml,ET-1 (92.92 ± 32.3) pg/ml] of ASD-nPH group.There were strong difference in plasma BNP levels and ET-1 levels among different degree PH groups(F =6.782,P < 0.05 ; F =8.475,P < 0.05).Statistical difference were also shown in BNP(F =6.846,P < 0.05) and ET-1 (F =9.327,P < 0.05) levels by compared difference altitude groups.The BNP levels are positively correlated with mean pulmonary artery pressure (r =0.326,P < 0.05),size of defect (r=0.301,P<0.05) and the altitude of habitation (r =0.252,P<0.05).Conclusion Plasma BNPand ET-1 levelsof ASD-PH group significantly higher than those of ASD-nPH group.By the increasing of the altitude and PH degree,the plasma BNP and ET-1 levels are increasing,which suggest that BNP and ET-1 play an important role on the proceeding and development of the PH and hypoxia promoted secretion of BNP and ET-1.
