Objective To explore the interactive effect of acupuncture and exercise on severe traumatic brain injury (TBI). Methods 120 comatose patients following TBI after routine surgery were equally divided into combined group (acupuncture and exercise), acupuncture group, exercise group, and control group (neither acupuncture, nor exercise). They were assessed with Glasgow coma scale (GCS),Fugl-Meyer assessment (FMA), modified Brathel index (MBI) and neurological deficit scores (modified Edinburgh-Scandinavia stroke scale, MESSS) before and after the treatment. Results The scores of GCS, FMA, MESSS and MBI improved more in the combined group than in the control group (P<0.05). The scores of GCS and MESSS improved more in the acupuncture group and the exercise group than in the control group (P<0.05). The scores of MESSS improved more in the combined group than in the exercise group (P<0.01). Conclusion Both acupuncture and exercise can synergetically reduce the disability and coma of comatose patients following TBI.

OBJECTIVE: To investigate the changes of ultrastructure of biliary epithelia with ischemic-type biliary lesion (ITBL) and the protection effect of exogenous growth hormone (GH) in order to provide experimental information for prevention of biliary complication after liver transplantation. METHODS: Rats underwent liver transplantation were randomized into control group, ITBL group and recombinant human growth hormone (rhGH) group (n=6, respectively). Each group was given drugs at the same day postoperation. 7 days later, the specimen of bile ducts was collected. The epithelial changes of biliary tract were observed with TEM, and the injury degree of the epithelia was analyzed quantitatively in a specialized image analysis system. The epithelial plane measurement parameters of each group were measured, including the density of area and quantity of epithelia, and the density of area of epithelial microvilli. RESULTS: As compared with control group, in ITBL group the integrity of bile ducts was destroyed, epithelial microvilli became sparse, the epithelial plane measurement parameters were significantly decreased (P
