[Effect of acupuncture at "Houxi" (SI3) and"Huantiao" (GB30) on high mobility group box 1 protein in spinal nerve trunk of rats with lumbar disc herniation].

Objective: To observe the effect of acupuncture at "Houxi"(SI3) and "Huantiao"(GB30) on high mobility group box 1(HMGB1) protein and mRNA in spinal nerve trunk(SNT) of rats with lumbar disc herniation(LDH), so as to explore the mechanisms of acupuncture at this paired points on the treatment for LDH.

Methods: SD rats were randomly divided into sham operation, model, conventional acupuncture(CA) and paired points(PP) groups (with 8 rats in each group). The LDH model was established by injection of autologous suspension made from rats' own nucleus pulsus into the epidural space.

Solid base for hydrogen sulfide removal in light oil.

Three solid bases, with three kinds of activated carbon as supporters and alkaline materials as active components, were tested for hydrogen sulfide removal in light oil. The solid bases have high intensity and greater adsorption capacity for hydrogen sulfide removal and are more easily regenerated.
