Objective To detect the expression of BMI-1, and to discuss its role in the development of gastric cancer. Methods The expression of BMI-1 protein and mRNA in gastric cancer and adjacent tissues was detected by immunohistochemical P-V method (78 cases) and semi-quantitative RT-PCR (30 cases). Results The positive expression rate of BMI-1 protein in gastric cancer patients was 66.7 % (52/78), and it was 19.2 % (15/78) in adjacent tissues, the difference was statistically significant (χ2= 35.815, P= 0.000). The expression of BMI-1 mRNA in 30 gastric cancer tissues was 0.23 ± 0.12, it was 0.03 ± 0.12 in adjacent tissues, the difference was statistically significant (t=8.372, P=0.000). The expression of BMI-1 protein and mRNA was correlated with the degree of tumor differentiation, depth of invasion, lymph node metastasis and TNM staging (all P< 0.05). Conclusion The expression of BMI-1 is closely related to the occurrence and development of gastric cancer, which may provide guidance for molecular pathogenesis, targeted therapy and prognosis of gastric cancer.

Objective To explore the effects of Jin's Three-needle Acupuncture combined with occupational therapy on function of upper limbs for stroke patients with hemiplegia. Methods 90 patients with stroke were randomly divided into control group (n=30), observation group (n=30) and experiment group (n=30). The control group received routine rehabilitation, the observation group received occupational therapy in addition, and the experiment group received Jin's Three-needle Acupuncture and occupational therapy in addition. They were assessed with Fugl-Meyer Assessment (FMA) of upper limbs and Barthel index (BI) before and 4 weeks after treatment. Results The scores of FMA and BI improved in all the groups after treatment (P<0.001). The difference of scores of FMA and BI before and after treatment were more in the experiment group than in the observation group (P<0.001), observation group than the control group (P<0.001). Conclusion Jin's Three-needle Acupuncture combined with occupational therapy can further improve the motor function of upper limbs and activities of daily living for stroke patients with hemiplegia.

BACKGROUND:Preliminary data showed that the application of human platelet lysate to human umbilical cord mesenchymal stem cell culture can better maintain the characteristics of stem cells than the application of serum-free medium. However, the serum-free medium can better improve the proliferation of mesenchymal stem cells in vitro than the human platelet lysate.OBJECTIVE:To screen out a better mesenchymal stem cell cultivation system that can greatly maintain the characteristics and proliferation rate of human umbilical cord mesenchymal stem cells.METHODS:Six human umbilical cord specimens were inoculated in six culture systems, and the primary culture of umbilical cord mesenchymal stem cell was performed. These six culture systems were respectively MesenCult serum-free medium with 2% human platelet lysate (group A), StemPro serum-free medium with 2% human platelet lysate (group B), MesenCult serum-free medium (group C), StemPro serum-free medium (group D), low glucose-DMEM with 10% fetal bovine serum (group E), low glucose-DMEM with 10% human platelet lysate (group F). The cells were subcultured at 14 days after inoculation to compare the effects of different culture systems on the morphology, surface markers, differentiation and proliferation of human umbilical cord mesenchymal stem cells.RESULTS AND CONCLUSION:(1) The morphology of passage 3 cells in group D was elongated and uneven in size. The morphology of passage 3 cells was flattened in groups E and F, but the cells in the other groups were spindle-shaped and uniform. There were no significant changes in morphology and size between passage 3 and 5 cells in A and B. In group C, the morphology of passage 5 cells was more flattened and uneven in size compared with passage 3 cells. In group D, the morphology of passage 5 cells was more elongated than that of passage 3 cell. In group E, the morphology of passage 5 cells was more flattened than that of passage 3 cells. There was no significant difference in morphology between passage 3 and 5 cells in group F. (2) The expression rate of cell surface markers had no significant difference at different passages in each group. (3) The adipoinduction and osteoinduction rates were relatively higher in groups A and B compared with groups E and F, and lowest in groups C and D. (4) The cell proliferation rate for each passages in group A was significantly higher than that in group C. The cell proliferation rate for each passage in group B was significantly higher than that in group D. The cell proliferation rate for each passage in groups E and F was significantly lower than that in groups A and B. To conclude, these results suggest that the combination of serum-free medium with human platelet lysate could better maintain the characteristics and the proliferation efficiency of mesenchymal stem cells.

Objective To investigate the effect of bone marrow mesenchymal stem cells (BMSCs) transplantation on angiogenesis and functional recovery after focal cerebral ischemia in rats.Methods BMSCs were isolated and cultured using the whole bone marrow adherent method,and conducted phenotypic identification using flow cytometry analysis of surface positive antigen of CD29,CD90 and the negative antigen of CD34,CD45.Rats were subjected to middle cerebral artery occlusion (MCAO) for 90 minutes,and divided into three groups randomly,the sham group,model group and BMSCs group.24 hours after cerebral ischemia,rats were injected with 1 ml BMSCs solution (1 × 106 cells/ml) or PBS via the tail vein.The modified neurological severity score(mNSS) test,the corner test and the adhesive tape test were used to evaluate sensorimotor function on the 1,7,14 and 28 days after ischemia.Infarcted volume was detected by toluidine blue staining,and the numbers of vWF positive microvessels and vascular endothelial growth factor (VEGF) positive cells in the ischemic boundary were determined by immunofluorescence.Results By flow cytometric analysis,the cell phenotype of passage 3 BMSCs showed that CD29,CD90,CD34 and CD45 were 98.3％,97.4％,0.2％ and 4.8％,respectively.Compared with the model group,BMSCs significantly reduced the score of mNSS(P＜0.01),the number of right turn of corner test(P＜0.05),latency of removal adhesive tape(P＜0.05) and the infarcted volume (P＜0.01).The numbers of vWF positive vesscls and the VEGF positive cells were (42.97±8.64)/mm2 and (54.83± 10.66)/mm2 at the boundary zone in model group 14 days after ischemia,respectively.BMSCs significantly increased the numbers of vWF positive vessels ((69.43± 7.29)/mm2) and VEGF positive cells ((78.70±6.16)/mm2,P＜0.01).Conclusion BMSCs can improve the functions of cerebral lesions after cerebral ischemia,which may be associated with the enhanced angiogenesis and VEGF expression in the ischemic boundary.

Objective To evaluate the efficacy of caudal block with dexmedetomidine mixed with lidocaine for management of perioperative analgesia in children. Methods Thirty pediatric patients, aged 2-6 yr, weighing 8-23 kg, scheduled for elective unilateral high ligation of hernial sac, were equally and randomly assigned into either lidocaine group ( group L ) or dexmedetomidine mixed with lidocaine group ( group DL) using a random number table. Each patient received a single caudal dose of 1% lidocaine 1 ml∕kg in group L. Each patient received a single caudal dose of 1% lidocaine 1 ml∕kg mixed with dexmedetomidine 1 μg∕kg in group DL. Postoperative analgesia was assessed using FLACC scale. When FLACC score ≥4, ibuprofen suspension 10 mg∕kg was given orally. The consumption of ibuprofen was recorded within 8 h after operation. The onset time of caudal block and duration of analgesia were recorded, and adverse effects were observed. Results Compared with group L, the onset time of caudal block was significantly shortened, the duration of analgesia was prolonged, and the requirement for ibuprofen was decreased in group L. There was no significant difference in adverse effects between the two groups. Conclusion Addition of dexmedetomidine 1 μg∕kg to caudal lidocaine can significantly optimize the efficacy of caudal block with lidocaine alone for the management of perioperative analgesia in children.
