Objective To discuss the diagnostic value of detecting plasma vitamin B12 and Homocysteine (Hcy) in subacute combined degeneration of the spinal cord (SCD).Methods Parents of SCD (n=29) and subjects (n=74) without spinal cord diseases were enrolled from the clinic of Shaanxi Provincial People's Hospital from April 2014 to July 2016.The plasma vitamin B12 and Hcy concentrations were detected using Chemiluminescence Immunoassay (CLIA) and enzyme-linked immuno sorbent assay (ELISA) respectively,and compared using chi-square between the SCD and control groups.Sensitivity rate,specific rate,and diagnose accordance rate were evaluated.Results The plasma homocysteine and vitamin B12 concentrations in SCD and control groups were 49.41 μmol/L vs 12.36 μmol/L,44.35 pg/ml vs 166.75 pg/ml,with significant differences (U=343.50,800.00,P<0.05).Negative correlation existed between the concentrations of vitamin B12 and Hey (r=-0.248,P=0.012).The sensitivity rates of vitamin B12 and Hcy detections were 55.2% vs 89.7%,which had significant differences (x2 =8.631,P=0.003),and the diagnose accordance rate (69.9% vs 64.1%) of the former was higher (x2 =4.175,P=0.041).Conclusion The plasma Hcy and vitamin B12 concentration detections had definite diagnostic value in SCD,and Hcy had higher sensitive rate,which can improve the diagnostic rate of SCD in the early stage.

This study examined the effect of resveratrol on the secretion of vascular endothelial growth factor (VEGF) and subsequent proliferation of human leukemia U937 cells, and explored the mechanisms involved. Human leukemia U937 cells were treated with resveratrol of different concentrations (12.5-200 micromol/L) for different time lengths (12-48 h). The proliferation of the U937 leukemic cells was determined by MTT assay. Apoptosis was observed by Annexin-V-FIFC/PI double staining and flow cytometry (FCM). Cells cycle was analyzed by PI staining and FCM. The content of VEGF was determined by ELISA. Human umbilical vein endothelial cells were examined for vasoformation in vitro after exposures to resveratrol of various concentrations. The results showed that resveratrol inhibited the proliferation of U937 leukemia cells in a dose-and time-dependent manner. Resveratrol induced apoptosis and S-phase cell cycle arrest in human leukemic U937 cells. Resveratrol inhibited the secretion of VEGF in U937 cells. Resveratrol inhibited the vasoformation of human vein endothelial cells in a dose-dependent manner. It was concluded that resveratrol could down-regulate the secretion of VEGF, induce apoptosis and suppress the proliferation of U937 cells.

Objective To establish the quality standard for Guishao Zhenxian Tablets. Methods Radix Glycyrrhizae,Radix Codonopsis,Radix Bupleuri were identified by TLC. The content of paeoniflorin in the preparation was determined by HPLC. Results The spots of TLC color spectrum were distinct and there was nointerference from the negative control. The calibration curve was linear over the concentration range of 0.245 2~0.735 6 ?g for paeoniflorin (r=0.999 7) and the average recovery was 98.3%,RSD=1.52% (n=5). Conclusion The established quality standard is convenient and reliable,and can be used to control the quality of Guishao Zhenxian Tablets more effectively.

This study was designed to determine the effects of the recombinant adeno-associated virus vector containing sense CD151 gene (rAAV-CD151) and antisense CD151 gene (rAAV-antiCD151) on the migration of Tca8113 cell. Functional fragment of CD151 gene was amplified by RT-PCR, and inserted into the vector pAAV in the sense direction and antisense direction, respectively. The rAAV-CD151 and rAAV-antiCD151 were produced and the titers were determined by dot blot. The CD151, at protein level, was detected by Western blot. The Transwell chamber was used to detect the effects of the rAAV-CD151 and rAAV-antiCD151 on the tumor cell migration. The titers of the rAAV-CD151 and rAAV-antiCD151 were 2 x 10(11) pfu/ml and 1.0 x 10(11) pfu/ml, respectively. The expression of CD151 was increased by 108% in the cells transfected with rAAV-CD151 and decreased by 79% in the cells transfected with rAAV-antiCD151, as compared with non-transfected cells, respectively. The number of the migrating cells was significantly increased in the cells transfected with rAAV-CD151 (93.56 +/- 11.59) and decreased in the cells transfected with rAAV-antiCD151 (24.00 +/- 4.36) as compared with non-transfected and rAAV-GFP transfected cells (53.00 +/- 6.56 and 46.00 +/- 7.00, P<0.05). It is an important molecular mechanism of the tumor metastasis that the overexpression of CD151 promotes the migration of the tumor cells. The rAAV-antiCD151 is a novel tool, which can reduce the expression of CD151 and inhibit the migration of the tumor cells, and brings us a new approach of anti-sene gene therapy targeted at CD151 in human carcinoma.

Objective: To seek the optimal acupuncture time for primary dysmenorrhea and provide clinical basis for optimal acupuncture treatment protocol. Methods:A total of 90 eligible cases were randomly allocated into three groups, 30 cases in each group. Points Guanyuan (CV 4), bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for patients in all three groups, with a different treatment duration: 15 min in group A, 30 min in group B and 45 min in group C. Then the clinical efficacy in each group was evaluated by pain symptom scoring. Results:As for the pain symptom scores, there were statistically significant intra-group differences between before and after treatment in three groups (allP<0.05); coupled with statistically significant inter-group differences between group B and the other two groups (bothP<0.05). As for clinical efficacy, there were statistical differences between group B and the other two groups (bothP<0.05), indicating that 30 min of acupuncture is the optimal duration in the treatment of dysmenorrhea. Conclusion:With the same needling manipulation, 30 min of acupuncture treatment achieves a better efficacy for primary dysmenorrhea.
