Objective To discuss the application value of small doses penehyclidine hydrochloride in painless colonoscopy examination. Methods From July 2012 to January 2013, 90 patients who planed to have painless colonoscopy were randomly divided into 3 groups with each group 30 cases. Before anesthesia, giving small doses of penehyclidine hydrochloride to small-dose group, giving conventional dose of penehyclidine hydrochloride to routine-dose group, and giving atropine intravenous administration to atropine group. Observe the smoothly de-gree, and check the heart rate, mean arterial pressure and postoperative adverse reactions of three groups. Results There was no obvious difference among the three groups in trems of smooth degree and oxyhemoglobin saturation. In small-dose group, heart rate and mean arterial pressure before and after the examination were better than that of routine-dose group and atropine group, and there were obviously lower inci-dence of postoperative adverse reaction compared with the routine-dose group and atropine group. Conclusion Giving small-dose of penehy-clidine hydrochloride before anesthesia of painless colonoscopy examination can significantly improve the effect of examination, and it can re-duce the incidence of postoperative adverse reactions.

ObjectiveTo investigate the expression of pro inflammatory cytokine mRNA including interleukin 1β (IL-1β), interleukin 6 (IL-6) and tumor necrosis factor-α(TNF-α) after spinal cord injury (SCI), and the effect of methylprednisolone (MP) on the expression of the cytokine and neurological outcome after SCI in rats.MethodsA moderate SCI model was made with SD rats according to modified Allen's method. 56 SD rats were divided randomly into the sham group (n=4), SCI group (n=24), saline group (n=14) and MP group (n=14, MP 30 mg/kg injected throuh tail vein 30 min after injury). Samples of injured spinal cord were taken at 1 h, 4 h, 12 h, 24 h, 72 h and 7 day after SCI. The mRNA expressions of IL-1β,IL-6 and TNF-α in the spinal cord of rats were measured by semi-quantitative RT-PCR at 1 h, 4 h, 12 h, 24 h, 72 h and 7 d post-injury, and 4 h post-operation in the control group. The effect of MP (30 mg/kg, iv, within 30 minutes post-injury) on the expression of cytokine at 4 h post-injury was tested with RT-PCR. The neurological outcome of rats was evaluated with BBB scores.ResultsThe expression of the cytokine mRNA was little in the sham group and significantly increased in injured groups with IL-1β at 12 h, TNF-αat 4 h reaching peak after injury,and higher than that in sham group until 72 h (P<0.05). While, the expressions of IL-1β and TNF -α mRNA were inhibited obviously in MP group at 4 h after injury, but MP had no effect on the neurological outcomes.ConclusionMP can inhibit inflammatory reaction obviously.

BACKGROUND: Hepatocyte transplantation can improve biochemical parameters and survival of animals with acute liver failure. However, cell sources, immunological rejection, distribution and histomorphological alternation of transplanted hepatocytes are important issues for its wide application in clinic. OBJECTIVE: To observe early-stage histomorphological and ultrastructural changes of SV40LT antigen gene transfected hepatocytes after transplanted into rat spleen. DESIGN, TIME AND SETTING: Randomized controlled animal trial was performed at Laboratory of National Hepatobiliary and Enteric Surgery Research Center, Ministry of Health from March to December 2001. MATERIALS: Sixty male Wistar rats were selected for hepatocyte transplantation. METHODS: Sixty rats were randomly divided into 4 groups (n=15). Primary cell group and primary cell plus cyclosporine A group were intrasplenically transplanted with primarily cultured hepatocytes; SV40LT antigen gene group and SV40LT antigen gene plus cyclosporine A group were intrasplenic transplanted with SV40LT antigen gene transfected hepatocytes. Twenty-four hours before and 14 days after transplantation, the rats in primary cell group and SV40LTor antigen gene group were injected with 0.5 mL normal saline through tail vein daily, while the other groups were injected with cyclosporine A (10 mg/kg per day). MAIN OUTCOME MEASURES: The spleen of one rat was harvested every day postoperatively for light microscopic and electron microscopic examinations to observe survival rate, histomorphological and ultrastructural features of transplanted hepatocytes for 14 days. RESULTS: Compared with primary cell group and SV40LT antigen gene group, the survival rate of transplanted hepatocytes in the other groups was significantly increased (P 0.05), while the survival rate in SV40LT antigen gene transfected hepatocytes was significantly higher than primarily cultured hepatocytes 8-14 days postoperatively (P
