Objective To observe the effect of ankle-foot orthosis(AFO)on the activities of daily living(ADL)and walking ability of patients with low lumbar spinal cord injury.Methods29 cases with low lumbar spinal cord injury were trained by systematic rehabilitation.According to patients' condition,static AFO or dynamic AFO were assembled for them.All patients were evaluated with Modified Barthel Index(MBI)and Functional Independence Measure(FIM)before and after training,and the walking distances were also measured.ResultsAfter AFO dressed,the ADL scores of patients increased,especially walking ability increased significantly(P<0.05).Of 29 patients,26 cases had outdoor walking ability,3 cases had domestic walking ability.ConclusionSelecting different kinds of AFO according to condition of individual can help patients with low lumbar spinal cord injury to reconstruct their walking ability and improve ability of self-management.

Objective To evaluate the clinical efficacy of acupuncture on sphenopalatine ganglion in the treatment of severe perennial allergic rhinitis (PAR) in a randomized controlled clinical trials. Methods A total of 81 patients with severe perennial allergic rhinitis were randomly divided into three groups: 27 in the observation group, 27 in the drug control group and 27 in the acupuncture control group. The patients in the observation group were treated with acupuncture on sphenopalatine ganglion; and the patients in the drug control group took Desloratadine; and the patient in the acupuncture control group were treated with acupuncture on Yintang (GV 29) and Yingxiang (LI 20). All the groups were treated for 4 weeks. The TNNS and VAS score system were tested before and after the treatment, and the nasal exhalation of nitric oxide (eNO) concentration level wa detected at baseline and each week's during treatments. Results After the treatment,the effective rate [80.8%(21/26)vs.64.0%(16/25),65.4%(17/26),x2=13.811]of the observation group was significantly higher than either the drug control group or the acupuncture control group (P<0.01). Compared to the score of the three group before treatment, the TNNS score was significantly lower (P<0.01) after the treatment. Compared with the drug control group, the level of eNO in nasal exhalation air (265.377 ± 36.475 ppb vs. 281.769 ±45.823 ppb vs. 295.231 ± 24.595 ppb, F=4.247) of the observation group and the acupuncture control group were significantly higher (P<0.05). Conclusions Acupuncture on the sphenopalatine ganglion can not reduce the eNO concentration level of nasal exhaled air in patients with perennial allergic rhinitis, but it can improve the symptoms of rhinitis. The clinical effect of acupuncture on the sphenopalatine ganglion was better than the desloratadine and acupuncture on GV 29 and LI 20.

Objective:To investigate the impact of non-alcoholic fatty liver disease (NAFLD) on the incidence of type 2 diabetes mellitus (T2DM) in an elderly population.Methods:A rural elderly population of Kunshan city, Jiangsu Province were used as the research subject. Prior diabetes mellitus, heavy alcohol consumption and incomplete data were excluded from prospective cohort study analysis. Annual physical examination and follow-up were conducted from 2007 to 2016. T2DM onset, death and loss to follow-up visits were observed as the research subject end points. According to the baseline physical examination results, the study subjects were divided into NAFLD and control groups, and further baseline data of both groups were analyzed whether there were match. The cumulative incidence rate of T2DM were statistically analyzed and compared between the two groups. Simultaneously, the relationship between the two groups of various indexes and the newly developed T2DM were analyzed using Kaplan-Meier. The variables with P < 0.1 were selected and incorporated into the Cox proportional hazard regression model. The impact of NAFLD on the incidence of T2DM was analyzed in an elderly population. Results:At baseline, there were statistically significant differences in the distribution of age, sex, waist circumference, body mass index, systolic blood pressure, diastolic blood pressure, direct bilirubin, blood urea nitrogen and triglycerides between NAFLD and non-NAFLD groups. However, fasting blood glucose, serum creatinine, total bilirubin, total cholesterol, low density lipoprotein cholesterol and high-density lipoprotein cholesterol had no statistically significant differences between the two groups. After nine years of follow-up, 207 newly developed T2DM cases, 52 NAFLD cases and 155 control group were selected as the study subjects. The cumulative incidence rates were 4.25%, 10.34%, and 3.55%, respectively. Kaplan-Meier analysis result showed that there were statistically significant differences in the cumulative incidence rates between the two groups from five-year. NAFLD had increased the T2DM risk in an elderly population by approximately 2.14 times (2.14 CI: 1.132 ~ 4.047) at five-year, and then had increased year by year thereafter. Univariate analysis showed that T2DM risk was 2.76 times higher in NAFLD than non-NAFLD groups (95% CI: 2.015 ~ 3.777). After adjustment for gender, age, body mass index, waist circumference, systolic blood pressure, diastolic blood pressure, serum creatinine, triglyceride, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol, T2DM risk ratio was 1.68 times higher in NAFLD than control groups (95% CI: 1.163 ~ 2.425). Conclusion:NAFLD is an independent long-term risk factor for the T2DM onset in an elderly population.

Objective: To explore whether long-term potentiation(LTP) induced by brain-derived neurotrophic factor(BDNF) of hippocampus is involved in the process of maternal separation(MS) leading to impaired cognitive function of offspring in adolescence. Methods: The newborn CD-1 mice were randomly divided into maternal separation group(MS group) and control group(CON group). Mice in MS group were separated from the mother mice for 3 h every day from postnatal day 4 to 21 while no intervention was taken in the CON group. The spatial learning and memory ability was assessed using Morris water maze at the age of 3 months. Western blot and real-time quantitative PCR were used to detect the levels of BDNF and BDNF mRNA in the hippocampus. LTP of the hippocampal CA3-CA1 neural pathway was recorded using electrophysiological techniques. Results: Compared with CON group, the latency and distance of Morris water maze in maternal separation group were significantly longer(P<0.01). The percentage of time and distance in target quadrant during the memory phase in MS group were obviously lower than those in control group(P<0.05). The results of WB and Real-time quantitative PCR in MS group showed that the levels of BDNF and BDNF mRNA in MS group apparently decreased(P<0.05). Compared with CON group, MS group showed a significantly lower LTP in CA3-CA1 neural pathway(P<0.01). Conclusion The certain intensity of maternal separation can impair learning and memory function in young CD-1 male mice, which may be associated with decreased expression of BDNF and impaired LTP in the hippocampus.

Objective: To investigate the effects of embryonic inflammation on the hippocampal synaptosomal-associated protein 25(SNAP-25) level and cognitive function in middle-aged. Methods: During gestational days 15-17, the CD-1 maternal mice received a daily intraperitoneal injection of lipopolysaccharides(LPS, 50 μg/kg) or the equal volume of normal saline, and the corresponding offspring were regarded as LPS group and CON group respectively. At the age of young(3-month-old) and middle-aged(15-month-old), the spatial learning and memory ability was assessed using Morris water maze(MWM), and the expression of hippocampal SNAP-25 protein was detected by immunohistochemical method and Western blot. Results: Compared with the 3-month CON group, the 15-month CON group had longer swimming distance(P<0.01), lower swimming distance percentage(P<0.01) in the target quadrant, and higher hippocampal subregions(CA1, CA3, DG) SNAP-25 levels(P<0.01). The same results were obtained in 15-month LPS group compared with 15-month CON group in learning and memory phase(P<0.05), and higher hippocampal subregions(CA1, DG) SNAP-25 levels(P<0.01). Pearson correlation analysis indicated that the hippocampal CA1 and CA3 subregions SNAP-25 level was positively correlated with the swimming distance, but negatively correlated with the percentage of swimming distance in the target quadrant. Conclusion Embryonic inflammation can accelerate the impairment of spatial learning and memory and the increase of hippocampal CA1 and CA3 subregions SNAP-25 protein in middle-aged CD-1 mice, and there may be a correlation between them.
