ObjectiveTo observe the efficacy of pricking cupping in treating herpes zoster at acute stage.MethodSixty patients with herpes zoster at acute stage were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by pricking cupping, while the control group was by oral administration of Western medicine. The total effective rate and the improvement of symptoms and pain at different stages were observed afterintervention.ResultThe total effective rate was 90.0% in the treatment group versus 86.7% in the control group, and the difference was statistically insignificant (P>0.05); after the first treatment course, the decreases of symptom score and pain indexin the treatment group were significantly superior to that in the control group (P<0.05); after the second treatment course, there were no significant differences in comparing the decreases of symptom score and pain index between the two groups (P>0.05).ConclusionPricking cupping is an effective approach in treating herpes zoster of the acute stage, as it can produce a comparatively higher total effective rate and also significantly improve the symptoms and pain.

Objective To study the effect of Tibetan MedicineManu-Xitanggranules on the expression of prostaglandin E2 and TNF-a on adjuvant arthritis (AA) rats.Methods A total of 60 rats were randomly divided into the control group, the model group, the Aspirin group, the low-, medium- and high- dose Manu-Xitang granules groups (each group with 10). Complete Freund's adjuvant method was used for the adjuvant arthritis model except the control group. All the groups started treatment at 8th day, and the treatment last 20 days. The low-, middle- high-dosage groups were treated with 2.0, 1.0, 0.5g/(kg body weight) Manu-Xitang granules, while the the Aspirin group with ASP (0.27 g/kg), control and medol groups with the equal Volume saline. The body weight, the swelling of primary side of arthritis index were observed. The levels of PGE2 and TNF-α were measured by ELISA.Results At 6th, 12th, 18th day, compared with the model group, the body weights in Aspirin group, the low-, middle-, high-dosage groups significantly increased (P<0.05 or P<0.01); at the 6th day, the foot swelling (0.40% ± 0.18%, 0.50% ± 0.25%, 0.55% ± 0.35%vs. 0.85% ± 0.15%) in the Aspirin group, middle-, and high-dosage groups significantly decreased (P<0.05 or P<0.01). And the PGE2 (0.66 ± 0.31vs. 0.39 ± 0.11) and TNF-a (0.72 ± 0.24vs. 0.50 ± 0.15) in the high- dose group were significantly lower than the model group (P<0.05).Conclusions The Tibetan medicineManu-Xitanggranules could treat AA through the changes of PGE2 and TNF-a.
