Objective To investigate the clinical efficacy of electroacupuncture incorporate with acupuncture point injection in treating cervical spondylotic radiculopathy.Methods 103 cases from Chen Jia Qiao Community Health Service Centre and other community centers during February 2011 to November 2012 were collected and randomly allocated into three group:a electroacupuncture group of 34 cases; an acupuncture point injection of another 34 cases and an observation group of 35 cases treated with electroacupuncture which incorporated with traction therapy.After the treatment,the therapeutic effects among three groups were compared.Results ① clinical efficacy comparing:total efficacy rate of observation group was 91.4％ (32/35),the electroacupuncture group was 73.5％ (24/34),the group treated with acupuncture point injection was 70.6％ (25/34).There were statistically significant differences between the observation group and the other two groups (Z=1.721,P＜0.05),while there's no statistically significant of comparison between the group treated with electroacupuncture and the group treated with acupuncture point injection (Z=2.473,P＞0.05).② NDI score comparing:NDI score of these three groups before and after treatment.Before treatment,the score of observation group was (12.32 ± 5.03) ; the electroacupuncture group was (12.96± 6.10) ; the acupuncture point injection group was (12.79±5.07),after treatment,the separate sore was (7.40±4.12),(6.08±3.60) and (6.08 ± 3.60) sequentially.There were statistically significant differences of NDI score of the three groups before and after treatment (P＜0.05).After treatment,the efficacy of observation group was better than the group treated with electroacupuncture and the group treated with acupuncture point injection(P＜0.05).③ signs or symptoms comparing:After treatment,there were statistically significant differences between the observation group and the other two groups on the aspect of relieving pain of neck and arm,numbness of arm and hand,and alleviating soreness when doing spurling test on cervical intervertebral foramen (Z-score is 2.603,2.862,2.307,P＜0.05).There's no statistically significant of comparison among three groups on the aspects of neck functional activities and segmental tenderness of cervical spondylosis (Z-score is 1.414,1.572,P＞0.05).Conclusion In treating cervical spondylotic radiculopathy,the total efficacy rate of electroacupuncture incorporate with acupuncture point injection was higher than only treat with electroacupuncture or acupuncture point injection.

Objective To investigate the effect of combination of cervical manipulation with cervical conditioning exercise for the treatment of cervical spondylosis of neck type or nerve root type. Methods Seventy-two patients were randomly divided into a treatment group (37 patients) or a control group (35 patients) by using a random number table. Patients in the treatment group and in the control group were treated with combination of cervical manipulation or cervical manipulation only, respectively. At the end of treatment and 3 months, treatment effects were assessed by Neck Disability Index (NDI) and Visual Analog Scale (VAS). Results NDI scores in both of the treatment group and the control group after treatment were significantly lower han those before treatment (t=4.471 in the treatment group, t=3.599 in the control group, all P<0.05), and NDI score in the treatment group were significantly lower than that in the control group after treatment (t=-2.085,P<0.05). Follow-up at 3 months, NDI score in the treatment group was significantly lower than that in the control group (t=-4.549, P<0.05). Proportions of improved patients, as assessed by NDI items, including pain intensity, personal care, lifting, reading, headaches, concentration, work, sleeping, driving and recreation in the treatment group were significantly higher than those in the control groups (Z=-3.521,-3.331,-3.003,-3.001,-3.265,-3.198,-3.016,-3.000,-2.102,-2.971, respectively, all P<0.05). VAS scores in both of the treatment group and the control group after treatment were significantly lower than those before treatment (t=7.986 in the treatment group, t=6.507 in the control group, all P<0.05), and VAS score in the treatment group were significantly lower than that in the control group after treatment (t=-2.426,P<0.05). Follow-up at 3 months, the VAS score in the treatment group was significantly lower than that in the control group (t=-7.065, P<0.05). Proportions of improved patients in the treatment group was significantly higher than that in the control group (91.89% vs 74.29%; χ2=4.014, P=0.045). Conclusion Combination of cervical manipulation with cervical conditioning exercise may be superior to cervical manipulation only for the treatment of cervical spondylosis of neck type or nerve root type.

To enhance speech recognition, as well as Mandarin tone recognition in noice, we proposed a speech coding strategy called zero-crossing of fine structure in low frequency (LFFS) for cochlear implant based on low frequency non-uniform sampling (LFFS for short). In the range of frequency perceived boundary of human ear, we used zero-crossing time of the fine structure to generate the stimulus pulse sequences based on the frequency selection rule. Acoustic simulation results showed that although on quiet background the performance of LFFS was similar to continuous interleaved sampling (CIS), on the noise background the performance of LFFS in Chinese tones, words and sentences were significantly better than CIS. In addition to this, we also got better Mandarin recognition factors distribution by using the improved index distribution model. LFFS contains more tonal information which was able to effectively improve Mandarin recognition of the cochlear implant.
