Objective To observe the clinical efficacy of electroacupuncture at different frequencies in treating post-stroke depression. Methods A hundred patients with post-stroke depression were randomized into treatment group 1, treatment group 2, treatment group 3, and a control group, 25 in each group. The treatment groups were intervened by electroacupuncture, while 2 Hz was adopted in treatment group 1, 50 Hz in treatment group 2, and 100 Hz in treatment group 3. The control group was intervened by oral administration of Sertraline Hydrochloride tablets. The Function Independent Measure (FIM) and Hamilton Depression (HAMD) scale were adopted for observation before and after intervention, and the clinical efficacies were compared. Results The FIM and HAMD scores were significantly changed after intervention in the four groups (P<0.05). After treatment, the FIM and HAMD scores in treatment group 1 were significantly different from that in treatment group 2 and 3 (P<0.05). The FIM score in treatment group 1 was significantly different from that in the control group (P<0.05). The total effective rate was 96.0%in treatment group 1, versus 92.0%in treatment group 2, 82.0%in treatment group 3, and 84.0%in the control group. The total effective rate in treatment group 1 was significantly different from that in the control group (P<0.05). Conclusions Electroacupuncture at 2 Hz, 50 Hz, and 100 Hz all can improve the activities of daily living and depression degree in patients with post-stroke depression, while 2 Hz ranks the top in comparing the therapeutic efficacy.

Objective To evaluate the variability of calculating thyroid volume by SPECT imaging at different time postinjection. Methods A total of 40 patients with Graves disease were enrolled in this prospective study using simple random sampling method. After intravenous injection of Na99TcmO4, all patients underwent planar and tomographic scintigraphy at different time points (5, 10, 15, 20, 25, 30, 45 and 60 min), and the planar or tomographic integral method were used to estimate thyroid volume. Data were analyzed by one?way analysis of variance, paired t test or linear correlation analysis. Results For thyroid volume esti?mated by planar imaging, the correlation coefficients between the different time points and 20 min were 0?717-0?819 (all P<0.05), and the CV was (18.38±5.31)%. For thyroid volume estimated by tomographic integral method, the correlation coefficients were 0.913-0.961 (all P<0.05), and the CV was (8.05± 3?19)%. Both the correlation coefficient and CV were statistically significant between the two methods ( t=-13.59, -11.29, both P<0.05) . Conclusions Tomographic integral method has better correlation and re?producibility in calculating thyroid volume compared with planar method.

[Objective]To observe the effect of opposing needling accompanying continual static stretch(CSS) on high-spasticity poststroke.[Methods]80 patients with high spasticity poststroke were randomly divided into four groups.A group:treated with opposing needling accompanying CSS;B group:treated with opposing needling;C group:treated with CSS;D group:acupoints selected from anti-spasm muscle.The therapeutic effect of the four methods was evaluated on proving spasm degree and motor function.[Results]Four methods had effect on high muscle tension in patients poststroke.The marks of Ashworth scale and Fugl-Meyer scale of the four groups had remarkable difference(P

ObjectiveTo evaluate the impact of omega-3 fatty acids intervention on clinical outcomes in postoperative patients with parenteral nutrition (PN). MethodsLiteratures relating to the evaluation of the clinical outcomes after supplementation with omega-3 fatty acids after selective surgeries were searched in databases including PubMed, EMBASE, Cochrane Library, Web of Science, Chinese Biomedical Databases, China National Knowledge Infrastructure, and Wanfang Database etc. All the eligible studies were randomized controlled trials and their results were published from January 1996 to June 2010. The methodological quality was assessed using Jadad scale, Schulz allocation concealment tool, and methodology review. Meta analysis was conducted using RevMan 5.1 software. The impact was described in terms of complications of infection, case-fatality rate, length of postoperative hospital stay, and length of postoperative ICU stay. ResultsTotally 320 articles were found and 17 randomized controlled trials ( n =1213 ) entered final meta analysis study. The results showed a significant decrease in the infectious complication rates of postoperative patients receiving omega-3 fatty acids intervention [risk ratio (RR) =0.44, 95％ confidence interval (CI) (0.30, 0.64), P ＜0.0001] ; meanwhile, the length of hospital stay was significantly shortened [mean difference (MD) =- 1.65 ; 95％ CI ( - 2.72, - 0.58), P =0.003]. However,the length of ICU stay showed no significant difference [MD =-0.31,95％ CI ( - 1.20, 0.58), P =0.500].ConclusionOmega-3 fatty acids interventions can benefit postoperative patients by reducing the morbidity of postoperative infectious complications and shortening the length of hospital stay.

Objective To compare the efficacies of transverse needling versus perpendicular needling at myofascial trigger points in treating cervical spondylosis and sift out a needling direction for a better improving effect on myofascial pain syndrome such as cervical spondylosis. Method One hundred and six patients with cervical spondylosis were randomly allocated to two groups. The transverse needling group received transverse needling at myofascial trigger points and the perpendicular needling group, perpendicular needling at myofascial trigger points. The symptoms and signs of cervical spondylosis were scored and the VAS score was recorded in the two groups before and after treatment. Result In the two groups, the VAS score had a statistically significant pre-/post-treatment difference (P<0.05) and decreased after treatment. The VAS score was significantly lower in the transverse needling group than in the perpendicular needling group after treatment, but there was no statistically significant difference between the two groups (P>0.05). In the two groups, the cervical spondylotic symptom and sign score had a statistically significant pre-/post-treatment difference (P<0.05) and decreased after treatment. The cervical spondylotic symptom and sign score was significantly lower in the transverse needling group than in the perpendicular needling group after treatment; there was a statistically significant difference between the two groups (P<0.05). The total efficacy rate was 94.0% in the transverse needling group, which was higher than 79.6% in the perpendicular needling group; there was a statistically significant difference between the two groups (P<0.05). Conclusion Both transverse needling and perpendicular needling can remove myofascial trigger points and treat cervical spondylosis, but transverse needling at myofascial trigger points is superior to perpendicular needling at myofascial trigger points.

Achievements of the 30-year research work on Pi-Wei Doctrine were summarized. They are: (1) ratio of salivin activity and excretion rate of D-xylose in patients with spleen deficiency are different from those in the normal subjects;(2) the principle of syndrome differentiation and treatment is embodied in the methodology of herbal medicine pharmacology for complex prescription; (3) the above findings are further confirmed by the research in molecular and cellular level which indicates that TCM syndromes and pharmacological mechanisms of herbal medicines have their material basis and the regulatory effect of complex prescription on TCM syndromes is actually the pharmacological mechanism of herbal medicines. It is suggested that the research of herbal medicine should be based on the guidance of traditional Chinese medicinal theory and carried out in clinical practice.
