Objective To investigate the effects of reciprocal inhibition on motor function connectivity in the brains of stroke patients.Methods Thirty patients with stroke were randomly divided into a treatment group (n =15) and a control group (n =15).The control group underwent normal limb positioning,medium frequency electrotherapy,circulated compression of the limbs,etc.The treatment group received conventional rehabilitation treatment plus reciprocal inhibition treatment for 30 min daily,6 times a week for 4 weeks.All of the patients were assessed before and after treatment using the Canadian neurological scale (CNS),the Frenchay activities index (FAI),the motricity index (MI) and functional magnetic resonance imaging of the motor cortex in a resting state (rs-fMRI).Results In both groups the average CNS,FAI and MI scores improved significantly.Compared with the control group,the changes in FAI and MI scores in the treatment group improved significantly more.The coefficient of functional connectivity of the bilateral motor cortex decreased significantly after treatment in both groups.In the treatment group the motor cortex functional connectivity correlated significantly with the improvements in MI scores.Conclusions Reciprocal inhibition can accelerate the improvement of extremity motor function and ability in the activities of daily living significantly after stroke.It reduces functional connectivity in the bilateral motor cortex in ways significantly correlated with improvements in motor function.

BACKGROUND:Interleukin-8 is an important inflammatory chemokine that plays an important role in the regulation of tumor cel proliferation and angiogenesis.
OBJECTIVE:To investigate the effect of interleukin-8 on the invasion and metastasis of CD133+hepatocel ular carcinoma stem cel s.
METHODS:After isolation and culture of MHCC97-H cel lines, CD133+/CD133-MHCC97-H cel s were sorted using immunomagnetic beads. CD133 expression was detected using flow cytometry, and interleukin-8 level in supernatant was measured using ELISA method. Cloning efficiency, tumorigenic capacity, cel migration and invasion ability were detected through colony formation assay, tumorigenesis experiment in nude mice, and Transwel detection. Additional y, other cel s were neutralized using interleukin-8 neutralizing antibody. Measurement results were compared between cel s undergoing different treatments.
RESULTS AND CONCLUSION:The CD133 level, interleukin-8 level, cloning efficiency and cel membrane permeability of CD133+MHCC97-H cel s were significantly higher than those of CD133-MHCC97-H cel s (P<0.05). Transplantation of CD133+MHCC97-H cel s at 1×106/L and 1×107/L resulted in subcutaneous tumors in some mice, whereas no subcutaneous tumors appeared in mice undergoing transplantation of CD133-MHCC97-H cel s at the same concentrations. After interleukin-8 neutralizing antibody treatment, the CD133 level, interleukin-8 level, and cloning efficiency of CD133+/CD133-MHCC97-H cel s were significantly decreased (P<0.05), especial y in the CD133+MHCC97-H cel s (P<0.01);the migration and invasion ability and cel membrane permeability of CD133+MHCC97-H cel s were significantly reduced (P<0.05), but these changes were not obvious in CD133-MHCC97-H cel s (P>0.05). These results show that interleukin-8 could be specifical y involved in the invasion and metastasis of CD133+MHCC97-H cel s.

BACKGROUND:As the existence of tumor stem cel s, it is difficult to completely eliminate tumors in clinic.
OBJECTIVE:To explore the tumor-kil ing effect of gastric cancer stem cel s as antigen to stimulate dendritic cel s combined with cytokine-induced kil er cel s.
METHODS:Side population cel s from human gastric cancer cel lines were isolated, and tumor antigen was prepared by freeze thawing method. After coculture with dendritic cel s, dendritic cel s combined with cytokine-induced kil er cel s, gastric cancer cel antigen, and gastric cancer stem cel antigen, kil ing rates of gastric cancer cel s were detected using MTT assay. Expression rate of CD83, a mature dendritic cel surface marker, was also detected.
RESULTS AND CONCLUSION:The CD83 expression level and kil ing rate of gastric cancer cel s were both significantly lower in the gastric cancer stem cel antigen group than the other groups (both P<0.05). These results indicate that gastric cancer stem cel s as antigen to stimulate dendritic cel s combined with cytokine-induced kil er cel s can promote the proliferation of gastric cancer cel s and elevate the ability to kil ing gastric cancer cel s.

Objective To explore the effect of quality control circle (QCC) on reducing the incidence of complications in the patients with peritoneal dialysis (PD). Methods Eighty-nine patients who underwent peritoneal dialysis after discharge were divided into QCC group (45 cases) and control group (44 cases) according to random sampling method. Both groups were followed up regularly, QCC activity was applied in patients of the QCC group on the basis of the QCC activity procedure. The intervention time was 1 year. The blood pressure, standard rate of urea clearance index, peritonitis incidence, catheter drift rate, infection incidences of external orifice of catheter, admission rate of complications and peritoneal dialysis withdrawal incidence between 2 groups were compared. Results After interference, the systolic and diastolic blood pressure in QCC group were significantly lower than those in control group:(124.11 ± 13.07) mmHg (1 mmHg=0.133 kPa) vs. (132.68 ± 12.09) mmHg and (72.13 ± 10.51) mmHg vs. (78.91 ± 11.79) mmHg, and there were statistical differences (P<0.05). The standard rate of urea clearance index in QCC group was significantly higher than that in control group:95.56%(43/45) vs. 81.82%(36/44), and there was statistical difference (P<0.05). After interference, the peritonitis incidence and admission rate of complications in QCC group was significantly lower than those in control group: 2.22% (1/45) vs. 13.64% (6/44) and 0 vs. 9.09% (4/44), and there were statistical differences (P<0.05). There were no statistical differences in catheter drift rate, infection incidences of external orifice of catheter and peritoneal dialysis withdrawal incidence between 2 group (P>0.05). The Spearman correlation analysis result showed that peritonitis was negatively correlated with education level (r = -0.28, P < 0.05), and standard rate of urea clearance index was positively correlated with education level (r = 0.21, P < 0.05). Conclusions The QCC management model can reduce the incidence of complications in patients with peritoneal dialysis.

BACKGROUND:It is reported that bone marrow mesenchymal stem cell(BMSC)transplantation might be a promising treatment for liver fibrosis.But the mechanism is still unclear.OBJECTIVE:To observe the hepatic stellate cells apoptosis induced by BMSC transplantation,and to study the mechanism of BMSC in treating hepatic fibrosis in vivo.METHODS:CCl_4 subcutaneous injection was performed to induce rat liver fibrosis.After 8 weeks of CCU injection,20 rats which underwent successful model establishment were randomly divided into experimental group and control group,10 in each group.The experimental group received MSC transplantation via tail vein injection,and the control group were given DMEM instead.The rats were killed and the livers were harvested at three time point,the day of MSC transplantation,3 days after transplantation,and 7 days after transplantation.The hydroxyproline content was detected by HE and Masson staining,and the expression changes of α-smooth muscle actin(α-SMA)proteins were determined using immunohistochemistry.The apoptosis of hepatic stellate cells were determined by α-SMA and TUNEL(terminal dUTP nick-end labeling)dual-staining.RESULTS AND CONCLUSION:After 8 weeks of CCU injection,the hydroxyproline content increased and histology indicated progress of liver fibrosis.At 7 days after MSC transplantation,the hydroxyproline in the liver was decreased,and the liver fibrosis was alleviated in the experimental group but aggravated in the control group.Immunohistochemistry indicated that α-SMA positive cells were increased at 8 weeks after CCU injection.At day 7 after transplantation,α-SMA positive cells in the experimental group were significantly less than control group(P ＜ 0.05).At 3 days after transplantation,the hepatic stellate cells apoptosis in the experimental group was significantly aggravated compared with control group(P ＜ 0.05).This suggested that MSC transplant was an effective treatment for liver fibrosis.MSC inducing hepatic stellate cells apoptosis may be one of the mechanisms.

Objective To evaluate the clinical feasibility of laparoscopic cool-tip radiofrequency ablation (LCRFA)for renal cell carcinoma. Methods Twelve selected cases of primary renal, ceil carcinoma underwent LCRFA. Of them, 4 cases of left renal carcinomas, 7 cases had right renal carci-nomas and 1 case had bilateral renal carcinomas. The maximum diameter of the tumors was 2.1-8. 5 era. Eleven cases were T, No M0 and the other one was T2 N0 M0. Results The mean operation time was 92±24 min, and the mean blood loss was 50±29 ml. None of the cases need blood transfusion post-operation. No laparoscopic operative complications were observed. Six weeks after operation, complete ablation was achieved in 12 lesions and partial ablation in 1, with a complete ablation rate of 92.3%(12/13). There was no statistic change of Hb. ESR. SCr and GFR after operations (P>0.05). Ten cases underwent CT examination 3 months after the treatment ,9 cases showed complete necrosis of tumor,1 case showed partial necrosis. No recurrence was found. All of the 12 cases remained sur-vived during the follow-up for 1-16 months(median,7.8 months). Conelusions LCRFA for renal cell carcinoma is an accurate and effective intervention with a low incidence of complications, and is more accurate than ultrasound-guided pereutaneous radiofrequency ablation.
