RESUMO
OBJECTIVE@#To observe the effect of Tiaoqi Jieyu (regulating qi and relieving depression) acupuncture on the clinical symptoms of treatment-resistant depression (TRD), and to explore the relationship between the acupuncture pain sensitivity and symptom's improvement.@*METHODS@#A total of 78 patients with TRD were randomly divided into an observation group (39 cases, 3 cases dropped off) and a control group (39 cases, 4 cases dropped off). The patients in the control group were treated with medications according to the treatment plan of psychiatrists (at least one medication was 5-hydroxytryptamine reuptake inhibitor). On the basis of the control group, the patients in the observation group were treated with Tiaoqi Jieyu acupuncture, and Baihui (GV 20), Yintang (GV 24+), Yanglingquan (GB 34), Taichong (LR 3), Hegu (LI 4), Neiguan (PC 6), Yinlingquan (SP 9) and Zusanli (ST 36), etc. were selected. The acupuncture was given three times a week. Both groups were treated for 8 weeks. After 8-week treatment, the response rate of Hamilton depression scale-24 (HAMD-24) score after was evaluated in the two groups. The scores of HAMD-24 and Hamilton anxiety scale (HAMA) were compared between the two groups before treatment, after 4, 8-week treatment and 12 weeks after treatment (follow-up). After the first treatment and 8-week treatment, the visual analogue scale (VAS) score in the observation group was evaluated, and the correlation between VAS score after the first treatment and HAMD-24 score before treatment, between VAS score after the first treatment and the course of disease in the observation group was analyzed, and the correlation between difference of VAS after 8-week treatment and after the first treatment and difference of HAMD-24 score before treatment and after 8-week treatment was analyzed.@*RESULTS@#After 8-week treatment, the response rate of HAMD-24 score in the observation group was 52.8% (19/36), higher than 17.1% (6/35) in the control group (P<0.001). Compared before treatment, the scores of HAMD-24 and HAMA in the two groups were decreased after 4-week treatment, 8-week treatment and in follow-up (P<0.05), and those in the observation group were superior to the control group (P<0.05). After 8-week treatment, the acupuncture pain VAS score in the observation group was (5.28±2.13) points, which was higher than (3.33±1.62) points after the first treatment (P<0.001). There was a negative correlation between VAS score after the first treatment and HAMD-24 score before treatment in the observation group (r =-0.486, P=0.003); there was no correlation between acupuncture pain VAS score after the first treatment and the course of disease in the observation group (P>0.05). After 8-week treatment, there was a positive correlation between the difference of VAS score and the difference of HAMD-24 score in the observation group (r =0.514, P=0.001).@*CONCLUSION@#Tiaoqi Jieyu acupuncture could improve the depression and anxiety in patients with TRD, and the symptom's improvement is related to the recovery of acupuncture pain sensitivity.

This study was designed to establish a high performance liquid chromatography (diode array detector, DAD)-tandem mass chromatography (HPLC-DAD-MS/MS) method for the simultaneously screening 12 kinds of cough-relieving chemical drugs illegally added in anti-cough and antiasthmatic traditional Chinese medicines. This method involved liquid chromatography-tandem mass spectrometry. The separation was conducted by Kromasil100-5C18 (250 mm × 4.6 mm, 5 μm) and the mobile phase was consisted of 0.3% ammonium formate (pH 2.97) and methanol. After separated by HPLC, the suspected components were analyzed by MS/MS and DAD and ultra scan was used to identify these illegally added drugs. A fast and sensitive HPLC-DAD-MS/MS method for the simultaneously screening for illegal chemical compositions was established. The LOD of these substances were below 50 ng. The method was sufficiently selective and sensitive to detect illegal chemical compositions in anti-cough and antiasthmatic traditional Chinese medicines.
RESUMO
<p><b>OBJECTIVE</b>To evaluate the analgesic effect of Corydalis yanhusuo on trigeminal neuropathic pain.in a rat model.</p><p><b>METHOD</b>Rat model of trigeminal neuralgia pain were established by inducing chronic constriction injury (CCI) of the infraorbital branch of the trigeminal nerve (ION). The effect of Corydalis yanhusuo, a traditional Chinese medicine, in ameliorating the pain was tested. Western blotting was performed to investigate the change of cannabinoid CB1 receptors in the Vc the injury of the infraorbital branch of the trigeminal nerve (ION-CCI). CB1 receptor antagonist AM 251 was applied to observe its effect on the analgesic effect of Yanhusuo.</p><p><b>RESULT</b>Administration of dl-THP (2 mg/kg) intraperitoneally increased the response threshold and the cut-off threshold to the mechanical stimulation in ION-CCI rat models. ION-CCI induced an upregulation of cannabinoid CB1 receptors within the ipsilateral of Vc. The effect of Yanhusuo was antagonized by the application of AM 251.</p><p><b>CONCLUSION</b>The analgesic effect of Yanhusuo involves the participation of CB1 receptors, suggesting that Yanhusuo may offer a useful therapeutic approach for trigeminal neuropathic pain.</p>
