Objective To explore the effect of early neuromuscular electrical stimulation (NMES) combined with sour taste therapy on dysphagia in the oral phase of acute/subacute ischemic stroke patients. Methods From January, 2013 to June, 2015, 90 patients with oral phase dysphagia after stroke were randomly assigned into NMES group (NM group), sour taste group (ST group ) and NMES combined with sour taste group (TO group) with 30 patients in each group. The swallowing function was evaluated with Functional Oral Intake Scale (FOIS) at baseline, three weeks and twelve weeks treatment. Results The change of FOIS was better in TO group than in ST group three weeks after treatment (P<0.01), and was better in TO group than in ST group and NM group twelve weeks after treatment (P<0.05). Conclu-sion An early application of NMES combined with sour taste therapy could improve the swallowing coordination, and reduce the the poten-tial complications in oral phase of acute/subacute ischemic stroke patients with dysphagia.

Objective:To investigate the effect of exogenous extopic fragile hisdidine triad (FHIT) gene on the apoptosis of gastric cancer cells induced by octreotide and elucidate the underlying mechanism. Methods: Human gastric cancer cell line MGC-803, which was loss of FHIT gene, was transfected with plasmid pRcCMV-FHIT and pRcCMV via lipofectamine mediation. After transfection, Western blotting was used to analyse the expression of FHIT protein in positive cells screened out by G418. The cells were treated with octreotide 10~(-10), 10~(-9), 10~(-8), 10-7, and 10~(-6) mol/L for 24, 48 and 72 h. Cell proliferation was evaluated by MTT assay and apoptosis by flow cytometry. The expression of bcl-2 and bax protein was detected with Western blotting.Results:FHIT protein expression was detected in MGC-803 gastric cancer cells after FHIT gene transfection. After treatment with octreotide 10~(-8) mol/L for 48 h, the apoptotic rate of MGC-803 cells transfected with FHIT gene was (26.777±1.702)%, significantly higher than that in empty vector group and untransfected group [(13.800±0.511)% vs (12.634±0.479)%, F=245.789, P<0.05]. The expression of bcl-2 protein was decreased while the expression of bax protein was increased in FHIT gene transfection group after octreotide treatment. Conclusion:The exogenous FHIT gene and octreotide had strong synergistic effects on apoptosis of MGC-803 cell lines, and their action mechanism may be related to the alteration of the expression of apoptosis-related proteins of bcl-2 family.

Objective The purpose of this study was to investigate the clinical features and the magnetic resonance imaging of brain of children with Japanese encephalitis (JE) and whether this relationship can be used in early diagnosis.MethodsMRI was performed in 145 children with JE.T1-weighted,T2-weighted and FLAIR of brain were obtained in 98 patients with 0.35 T MRI system and conventional MRI and DWI were performed in 47 patients with 1.5 T MRI system.The position,range and MRI features were analyzed.ResultsMR imaging studies of 106 patients showed hyperintensity in the thalamic with 87 patients involved the caudex cerebri,as seen on T2-weighted images.The lesions were also seen in basal ganglia (32 cases),cerebral cortex (43 cases),cerebellum (2 cases),and white matter (15 cases).Lesions showed high intensity signal on T2WI and T2-FLAIR,and iso- or low intensity on T1WI.The number of the lesions in FLAIR were more than T2WI.The positive rate on 1.5 T MRI (87.2%) was higher than that on 0.35 T MRI(66.3%,χ2＝7.06,P＜0.01).ConclusionsMultiple brain tissues can be involved and the thalamic and the caudex cerebri involvement are the conspicuous characteristics in children with JE.T2-FLAIR and DWI are helpful in the early diagnosis of JE.

Objective To identify the effect of health risk behaviors on accidental injury of adoles-cents.Then analyze the strength and approach of the health risk behaviors. Methods Cluster sampling on various stages and strata methods was adopted. The adolescents from grade one to three in junior school students and grade one to three in senior high school students completed the questionaire. A total of 4408 students were surveyed and 4309 samples were valid. Path analysis was used to understand how factors could influence injury incidence. Results The incidence of adolescent injury was 15.53%. Statistical differences were found between genders (male 17.77%,female 13.36%,χ2=15.91, P<0.01),education levels (junior high school 17.36%,senior high school 13.99%,χ2=11.45, P<0.01) and cities ( Beijing 12.97%,Zhongs-han 17.95%,χ2=20.33, P<0.01) . Those who got injured were found with more health risk behaviors. Health risk behavior was the direct influencing factor to injury,as well as a possible risk factor to multiple injuries. Conclusion Health risk behaviors can strongly affect adolescent injury,and can be an indicator. Reducing health risk behaviors is important in adolescent injury prevention.

BACKGROUND:Traditional internal fixation for thoracolumbar vertebral fractures easily causes poor vertebral reduction, and postoperative vertebral height loss easily appears.
OBJECTIVE:To analyze the feasibility of lateral-position pedicle screw placement in spinal surgeryvia combined anterior-posterior approaches.
METHODS: A total of 36 cases undergoing spinal surgical operation in the Baoji City Chinese Medicine Hospital from February 2013 to October 2014 were enroled in this study. The patients were divided into two groups according to the method of repair. 18 patients in the control group received prone-position pedicle screw placement, and 18 patients in the experimental group received lateral-position pedicle screw placementvia combined anterior-posterior approaches. Postoperative CT and X-ray examinations compared the adverse rate of screw placement and the rate of nerve root injury between the two groups. Operation time, length of stay, time of beginning movement, intraoperative blood loss and American Spinal Injury Association impairment scale score were compared between the two groups.
RESULTS AND CONCLUSION:Significant differences in the adverse rate of screw placement and the rate of nerve root injury were detected between the two groups (P < 0.05), and the adverse rate of screw placement and the rate of nerve root injury were better in the experimental group than in the control group. Operation time, length of stay, and time of beginning movement were significantly better in the experimental group than in the control group (P < 0.05). Intraoperative blood loss was significantly lower in the experimental group than in the control group (P < 0.05). American Spinal Injury Association impairment scale scores were significantly higher in the experimental group than in the control group (P < 0.05). These findings confirm that lateral-position pedicle screw placementvia combined anterior-posterior approaches in spinal surgery can reduce intraoperative trauma, shorten the length of hospital stay, and promote functional recovery of spinal cord.
