Objective To investigate the effect of caffeic acid phenethyl ester (CAPE) on the growth of human colorectal carcinoma cell line HCT116 transplanted subcutaneously in nude mice. Methods Nude mouse model of human colorectal carcinoma by subcutaneous transplantation of HCT116 cell line was reproduced. A total of 20 mice were divided into 2 groups: control group and CAPE group (oral administration of CAPE at 5mg/mice/d). The growth of the subcutaneously transplanted tumor and changes in mouse body weight in each group after treatment were observed on 7, 14, 21 and 28d. Histopathological examination of xenograft, heart, liver, lung, kidney and intestine of nude mice was also conducted. Apoptosis index was detected by terminal dUTP nick end labeling (TUNEL) technique. Results CAPE had significantly inhibitory effect on growth of the transplanted xenograft in vivo. Tumor volume and tumor weight were decreased (P

Objective To investigate the role of APE1 in the carcinogenesis and progression of colorectal carcinoma (CRC). Methods Expression of APE1 was determined with SP immunohistochemical technique in 40 specimens of normal colorectal mucosa, 60 specimens of colorectal mucosa adjacent to CRC, 72 specimens of colorectal adenoma, and 125 specimens of colorectal carcinoma. Results In normal colorectal mucosa, APE1 was detected in nuclei of epithelial cells. Shift of APE1 from nucleus to cytoplasm was observed in 6 of 60 (10%) specimens of mucosa adjacent to cancer. Such shift was observed in 92 of 125 (73.6%) CRC tissues and 60 of 72 (83.3%) colorectal adenoma, the incidence of both of them was significantly higher than that observed in normal colorectal mucosa and colorectal mucosa adjacent to CRC (P

Objective To investigate the effect of elispheric motion on balance and walking ability of hemiplegic patients after stroke. Methods From September to December, 2016, 40 hemiplegic patients after stroke were randomly divided into control group (n=20) and ob-servation group (n=20). Both groups received conventional rehabilitation, additionally, the control group received juggling ball training, and the observation group received elispheric motion combined with juggling ball training, 20 minutes a day, six days a week for six weeks. They were assessed with the Fugl-Meyer Assessment-Sensory (FMA-S), Fugl-Meyer Assessment-Lower Extremity (FMA-LE), Berg Bal-ance Scale (BBS) and TimedUp and GoTest (TUGT) before and six weeks after training. Results After training, the scores of FMA-S, FMA-LE, BBS significantly increased (t>10.012, P<0.05) in both groups, and were higher in the observation group than in the control group (t>2.129, P<0.05);the time of TUGT significantly shortened (t>10.001, P<0.001) in both groups, and were shorter in the observation group than in the control group (t>4.669, P<0.05). Conclusion Elispheric motion can facilitate to improve the balance and walking ability of hemi-plegic patients after stroke.

Objective To investigate the influence of bushenhuoxue drug-containing serum on PI3K and Akt signaling pathway in purified retinal ganglion cell (RGCs) in vitro of Sprague-Dawley (SD) rats,and to explore the protective mechanisms of bushenhuoxue recipe on RGCs.Methods At first,bushenhuoxue drug-containing serum was prepared,and the RGCs of SD rats were purified;after the apoptotic model of pressurized and purified RGCs was established successfully in vitro using open pressure control system,RGCs were dealt with 50 g · L-1,100 g · L-1,200 g · L-1 concentration gradient of bushenhuoxue drug-containing serum.Then the subjected cells were divided into normal culture group (N group),control group (C group),50 g · L-1 bushenhuoxue group (50 g · L-1 BSHX group),100 g · L-1 bushenhuoxue group (100 g · L-1 BSHX group),200 g · L-1 bushenhuoxue group (200 g · L-1 BSHX group).Finally,cell apoptotic rate was detected by Annexin V-FITC/PI staining,while real-time quantitative PCR (qRT-PCR) and Western blot were used to detect the mRNA and protein expression of PI3K and Akt in each group respectively.Results The results of qRT-PCR detection showed that PI3K,Akt mRNA expression level in C group (0.04 ±0.01) was decreased compared with N group (1.00 ± 0.04),and the difference was statistically significant (all P＜0.05),while PI3K,Akt mRNA levels in 50 g · L-1,100 g · L-1 and 200 g · L-1 BXHX group (0.18 ±0.01,0.21 ±0.02,0.22 ±0.01,0.36 ±0.01,0.84 ±0.10,1.07 ± 0.17) were increased compared with the C group,and the difference was statistically significant (all P ＜0.05).The Western blot results of each group showed that PI3K,Akt protein expression level in C group was decreased compared with N group,with statistical difference (all P ＜ 0.05),while PI3 K,Akt protein expression levels in 50 g · L-1,100 g · L-1 and 200 g · L-1 BSHX group were increased compared with C group,with staffstical difference (all P ＜ 0.05).Conclusion Bushenhuoxue drug-containing serum may inhibit the RGCs apoptosis induced by pressure,which may be related to the activation of PBK/Akt signal transduction pathway.

Objective To observe the effects of repetitive transcranial magnetic stimulation (rTMS) combined with abdominal muscle electrical stimulation on the pulmonary ventilation of patients with cervical spinal cord injury.Methods Twenty-five patients with cervical spinal cord injury were randomized into an experimental group (n =13) and a control group (n =12).The control group was given comprehensive rehabilitation treatment,including upper limb movements,standing training and training of respiratory function,while the experimental group was given repetitive transcranial magnetic stimulation and abdominal muscle electrical stimulation in addition to the comprehensive rehabilitation treatment.The patients' maximum lung capacity (VC),forced expiratory volume for 1 second (FEV1),peak expiratory flow rate (PEF) and tidal volume (VT) were measured at the outset and after 3 months of treatment.Results The lung function indexes increased in both groups after treatment,but each index improved significantly more in the experimental group,on average,than in the control group.Conclusion As a supplement to routine respiratory function training,repetitive transcranial magnetic stimulation combined with abdominal intermediate frequency electrical stimulation can improve the pulmonary ventilation function of patients with middle and lower cervical spinal cord injury.

Objective To investigate the correlation between G753A and C1040T polymorphisms in the gene encoding region of thrombin-activatable fibrinolysis inhibitor (TAFI )and cerebral infarction in patients with cerebral infarction in Chinese Han population. Methods C1040T and G753A poly-morphisms in the TAFI gene encoding region in 130 patients with cerebral infarction and 118 healthy subjects (control group)were analyzed retrospectively and they were detected by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP ). Results The GG genotyping of the TAFI gene G753A polymorphism in the cerebral group was 41. 5%(n=54)and the A allele carriers were 58. 5%(n=76),while those in the control group were 44. 9%(n=53)and 55. 1%(n=65)respectively. There were no significant differences in the GG genotyping of TAFI gene G753A polymorphism and the A allele carriers between the cerebral infarction group and the control group (χ2 =0. 288,P=0. 592). In the cerebral infarction group,the CC genotyping of C1040T polymorphism was 50. 0%(n=65)and T allele carriers were 50. 0%(n=65),while those in the control group were 51. 7%(n=61)and 48. 3%(n=57)respectively. There were no significant differences in the GG genotyping of C1040T polymorphism and the T allele carriers between the two groups (χ2 =0.071,P =0.790 ). Multivariate logistic regression analysis showed that G753A and C1040T single nucleotide polymorphisms (GA or AA genotype)in the TAFI gene encoding region were not the independent risk factors for cerebral infarction. Conclusion There are no significant differences in the correlation between the G753A and C1040T polymorphisms in the TAFI gene encoding region and cerebral infarction. They are not the independent risk factors for the onset of cerebral infarction.

Objective To study the effect of caffeic acid phenethyl ester (CAPE) on the expression of ?-catenin in the cultured colorectal cancer cell lines. Methods HCT116 and W480 cells were treated with CAPE at serial concentrations of 2.5, 5, and 10 mg/L. ?-catenin protein expression was assayed by Western blot analysis. ?-catenin localization was detected by indirect immunofluorescence. Results CAPE treatment was associated with decreased total ?-catenin protein expression. The expression of ?-catenin at the cell nucleus and cytoplasm was downregulated, but at the cell-cell linked site the ?-catenin protein expression was upregulated. Conclusion CAPE can downregulate the expression of ?-catenin and inhibit the translocation of ?-catenin to nucleus, which may play an important role in the anticancer activity of CAPE.

Objective To observe the effects of intensive lower extremity motor control training on the motor function of lower extremity, balance and walking capability of stroke patients. Methods 40 stroke patients were randomized into the intervention group (n=20) and control group (n=20). Both groups received the routine rehabilitation, while the intervention group accepted the lower extremity motor control training in addition for 6 weeks. Before and after 6 weeks of treatments, they were assessed with Fugl-Meyer Assessment of lower extremity (FMA-L), Berg Balance Scale (BBS), Holden Functional Ambulation Category (FAC); their gaits were analysesd with footprint. Results Both groups improved significantly in scores of FMA-L, BBS, FAC and average step length, stride width, walking velocity (P<0.01) after treatment, and improved more in the intervention group than in the control group (P<0.05). Conclusion Intensive motor control training of lower extremity may promote the recovery of motor function of lower extremities, balance and walking ability of stroke patients.
