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.

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.

Objective To observe the therapeutic efficacy of acupuncture at myofascial trigger points (MTrPs) in treating cervical spondylosis of vertebral artery type. Methods Ninety-eight patients with cervical spondylosis of vertebral artery type were randomized into a treatment group of 51 cases and a control group of 47 cases. The treatment group was intervened by acupuncture at the MTrPs, while the control group was by injection of medical solution for anti-inflammation and analgesia. The positive rate of rotate-cervix test, dizziness score, and visual analogue scale (VAS) of the head and neck pain were compared before and after intervention. Results After intervention, the positive rate, dizziness score, and VAS score were significantly changed in both groups (P＜0.05). There were significant differences in comparing the positive rate, dizziness score, and VAS score between the two groups after intervention (P＜0.05). The total effective rate was 96.1%in the treatment group versus 76.6%in the control group, and the difference was statistically significant (P＜0.05). Conclusion Acupuncture at the MTrPs can improve the dizziness and head-neck pain in patients with cervical spondylosis of vertebral artery type.

Objective To compare the effects of sevoflurane and propofol anesthesia on inflammatory response and pulmonary function during perioperative period in patients undergoing lung cancer resection．MethodsThirty ASA Ⅰ or Ⅱ patients(23 male，7 female) aged 41-64 yr having a body weisht index of 22-30 kg/m2 undegoing elective left lower lobe resection were randomlydivided into 2 groups(n=15 each)：sevoflurane group (group S) and propofol group(group P)．Anesthesia was induced with 6％-8％ sevoflurane or propofol 2 mg/kg and fentanyl 4-6 μg/kg．Intubation with double lumen catheter was facilitated with vecuroniunl 0．1 mg/kg． Anesthesia was maintained with 1％-3％ sevoflurane/propofol infusion(6-10 mg·kg-1·h-1)and intermittent iv boluses of fentanyl and vecuronium．Radial artery was cannulated．Swan-Ganz catheter was placed via right internal jugular vein．The patients were mechanically ventilated．During one lung ventilation(OLV)I：E and VT were adjusted to maintain airway pressure <30 cm H2O．Arlerial and mixed venous blood samples were collected for blood gas analysis before induction of anesthesia(T0)，before OLV(T1)，at the end of OLV(T2)，when the chest was closed(T3) and at 24 h after operation (T4)．PA-aO2，Qs/Qt and respiratory index(RI，PA-aO2/PaO2) were calculated. Serum matrix metallo-proteinase-9 (MMP-9) and MDA were measured at T0, T3 and T4. Dynamic lung compliance (Cd) was calculated at T1-3 .Results PA-aO2, RI and Qs/Qt at T1-3 and serum MMP-9 and MDA concentrations at T3 were significantly increased as compared with the baseline values at T0 in both groups. In group S, Cd was significantly lower at T3 than at T1.PA-AO2, and serum MMP-9 and MDA concentrations at T3, RI at T2,3 and Qs/Qt at T1-3 were significantly higher in group S than in group P. Conclusion The inflammatory response is lower and the injury to pulmonary function is lighter during propofol anesthesia than sevoflurane anesthesia in patients undergoing lung cancer resection.
