Objective To observe the clinical efficacy of acupuncture plus contralateral needling in treating post-stoke myodystonia. Method Totally 120 patients with post-stroke myodystonia were randomized into group A, B, C and D, 30 in each group. Group A was intervened by yin-reducing and yang-tonifying needling method plus contralateral needling; group B was by ordinary acupuncture plus contralateral needling, group C was by yin-reducing and yang-tonifying needling alone, while group D by ordinary acupuncture. Clinical Spasticity Index (CSI) was observed before and after intervention. Result After treatment, the CSI scores (tendon reflex, muscle tension, episodic spasm scores and total score) were significantly changed in the four groups (P<0.01, P<0.05). The tendon reflex score, muscle tension score and total score in group A were significantly different from that in the other three groups after intervention (P<0.01,P<0.05). There was a significant difference in comparing the episodic spasm score between group A and D after intervention (P<0.01). There were significant differences in comparing the tendon reflex score, muscle tension score and total score between group B and D after intervention (P<0.05). The total score in group C was markedly different from that in group D after intervention (P<0.05). Conclusion Yin-reducing and yang-tonifying needling method plus contralateral needling is an effective method in treating post-stroke myodystonia.

An HPLC method for the determination of 18alpha-glycyrrhetinic acid and 18beta-glycyrrhetinic acid in rat plasma was established, which was used subsequently to determine the pharmacokinetic profiles of both epimers of glycyrrhetinic acid in rats. alpha-glycyrrhetinic acid, beta-glycyrrhetinic acid, and a mixture of alpha-glycyrrhetinic and beta-glycyrrhetinic acids were administered to rats via gastric infusion. Blood samples were collected at different time intervals and extracted by liquid-liquid extraction. Separation was achieved by using a Kromasil C18 column (150 mm x 4.6 mm, 5 microm) with the mobile phase composed of acetonitrile--4 mmol x L(-1) ammonium acetate solution (46 : 54, v/v) at a flow rate of 1.0 mL x min(-1), and the detection wavelength was set at 250 nm. The pharmacokinetic parameters were calculated using the software DAS 2.0. In a combined administration, the main pharmacokinetic parameters of beta-glycyrrhetinic acid are significantly different from that of alpha-glycyrrhetinic acid (P < 0.05), while no significant difference was obtained when administrated individually. Compared to the single administration, significant differences (P < 0.05) on the values of AUC(0-t) and AUC(0-infinity) of beta-glycyrrhetinic acid were observed when this chemical was administrated together with alpha-glycyrrhetinic acid. In contrast, the pharmacokinetic parameters of alpha-glycyrrhetinic acid were not affected even under the co-administration. Here, a sensitive, specific, rapid and reproducible HPLC method was developed for the pharmacokinetic studies of alpha-glycyrrhetinic acid and beta-glycyrrhetinic acid in rat plasma.

Aim Toinvestigatetheanalgesiceffectsof epidural osthole application on the mechanical allodyn-ia and the ERK/MAPK signaling pathway and the expression of COX-2 mRNA in the spinal dorsal horn.Methods 125adultmaleSDratswererandomizedin-to five groups( n=25 each) :Blank, Sham, NP, Ost and vehicle. At postoperative day 6, 1mg/rat osthole 50 μl was injected epidurally into group Ost and the same volume of vehicle was given into group vehicle. The mechanical pain threshold was measured by 50%MWT at 1 day before operation and the 3 rd,6 th,7 th, 14 th,21 st day after operation. After the measurement of pain threshold on postoperative day 14 , the L4-6 segment of spinal dorsal horn was removed for determi-nation of the expression of ERK, pERK and COX-2 mRNAbyWesternblotandRT-PCR.Results Com-pared with blank group, the mechanical pain threshold was only down-regulated at day 1 after operation in sham group, the expression of pERK and COX-2 mR-NA in sham group showed no significant difference ( P>0. 05 ); the mechanical pain threshold was signifi-cantly down-regulated after operation in NP, Ost and vehicle groups( P<0. 05 ) and the expression of pERK and COX-2 mRNA was significantly increased ( P <0. 05). Compared with vehicle group, the pain thresh-old in Ost group was significantly increased after drug administration( P<0. 05 ) and the expression of pERK and COX-2 mRNA was significantly reduced ( P <0. 05 ) . The expression of ERK showed no significant difference among each group(P>0. 05). The correla-tion analysis on pERK1/2 and COX-2 mRNA revealed the Pearson correlation coefficient was 0 . 878 and 0 . 910 , suggesting a strong positive correlation between pERKandCOX-2mRNA.Conclusions Ostholead-ministrated in the early stage after surgery can alleviate the nucleus pulposus-induced radicular inflammatory pain probably by inhibiting the expression of pERK and COX-2 mRNA in spinal dorsal horn.
