Objective To explore feasibility of monitoring the extremital arterial blood supply and venous blood circulation in rabbits with replanted limb by Na~(99m)TcO_4 trace imaging(TTI). Methods TTI was performed on 6 normal control rabbits and 30 rabbits with replanted limb at 24～36h after replantation. The radioactivity uptake ratio of replanted limb/normal limb(T/NT) was analyzed. Imaging was classified into ?,Ⅰ,Ⅱand Ⅲ scales according to the accumulation amount of extremital radionuclide. Then an exploratory operation was performed on each rabbit. Results Rabbits with ?,Ⅰ,Ⅱand Ⅳ scales had 8,6,15(including 6 normal control rabbits),and 7 animals, respectively, and their T/NT were 0.178?0.072, 0.461?0.046, 0.816?0.074, 1.14?0.086(P1.05) may serve as a qualitative and semiquantitative diagnostic standard for venous blood circulation block. Conclusion TTI was feasible in monitoring the extremital arterial blood supply and venous blood circulation in patients with replanted limb(finger).

OBJECTIVETo evaluate the clinical efficacy of YANG's pricking-cupping therapy for knee osteoar thritis (KOA). Methods This was a multi-center randomized parallel controlled trial. One hundred and seventy one patients with KOA were randomly allocated to a pricking-cupping group (89 cases) and a conventional acu puncture group (82 cases). Neixiyan (EX-LE 4), Dubi (ST 35) and ashi points were selected in the two groups. Patients in the pricking-cupping group were treated with YANG's pricking-cupping therapy; the seven-star needles were used to perform pricking at acupoints, then cupping was used until slight bleeding was observed. Patients in the conventional acupuncture group were treated with semi-standardized filiform needle therapy. The treatment was given for 4 weeks (from a minimum of 5 times to a maximum of 10 times). The follow-up visit was 4 weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the visual analogue scale (VAS) were adopted for the efficacy assessments.

RESULTSThe pain score, stiffness score, physical function score and total score of WOMAC were all reduced after 4-week treatment and during follow-up visit in the two groups (all P<0. 0001). Except that the difference of stiffness score between the two groups was not significant after 4-week treatment (P>0. 05), each score and total score of WOMAC in the pricking-cupping group were lower than those in the conventional acupuncture group after 4-week treatment and during follow-up visit (P<0. 0001, P<0. 01). After 2-week treatment, 4-week treatment and during follow-up visit, the VAS was all reduced compared with that before treatment (all P<0. 0001) ; with the increase of the treatment, the reducing trend of VAS was more significant (P<0. 0001). The scores of VAS in the pricking-cupping group were lower than those in the conventional acupuncture group after 4-week treatment and during follow-up visit (P < 0. 01, P <0. 0001). CONCLUSION The YANG's pricking-cupping and conventional acupuncture therapy can both significantly improve knee joint pain and function in patients with KOA, which are relatively safe. The pricking cupping therapy is superior to conventional acupuncture with the identical selection of acupoints.
