Objective To improve the diagnosis and treatment level and to decrease the mortality of neonatal colon perforation.Methods To analyse seventeen cases of neonatal colon perforation from 1996 to 2006.Results The cure rate is 69.4%,mortality rate is 23.5%,and one out of seventeen was given up for treatment.The reasons of neonatal colon perforation were more complex compared with diagnosis,and the mortality of neonatal colon perforation were high.Conclusions The key to decrease the mortality is early diagnosis,perioperation treatment and early operation.

Objective To evaluate the outcomes of transanal coloanal pull-through with resection of the internal anal sphincter in neonates and infants with Hirschsprung's disease.Methods Transanal coloanal pull-through with resection of the internal anal sphincter was performed on 101 neonates or infants with Hirschsprung's disease in our hospital.An incision slightly longer than one-half of the rectal circumference was made at the dentate line.Then,the muscular layer of the anterior rectal wall was dissected and separated upwards from the submucosal layer;meanwhile that of the posterior wall was also separated upwards along the rectal longitudinal muscles.After the muscular layer was separated to the level of the peritoneal reflection,a radial operation was performed by resecting the internal anal sphincter and muscle sheath of the posterior rectal wall.Results The operation was accomplished successfully in all the patients with less than 10 ml of intraoperative blood loss.The operation time ranged from 45 to 190 min(mean,90 min).No complications,including urine retention,incision infection,and anastomotic stenosis,occurred.Two patients(2/86,2.3%) developed enterocolitis after the operation.The incidence of fecal soiling was 27%(22/82) at 2 months after the operation,and then decreased to 4%(3/82) at 6 months.Anorectal manometry was performed on 78 patients at 1,2,3,and 6 months postoperatively.The results demonstrated that the anal resting pressure after the operation was significantly lower than that before the operation(P

To investigate the effect of the localization of oligonucleotides decoy (ODNs decoy) on the activation of nuclear factor-kappaB (NF-kappaB) in TNF-alpha induced HeLa cells. The mercapto group-modified nuclear localization signal (NLS) peptide was covalently conjugated to amino group-modified NF-kappaB ODNs decoy by Sulfo-SMCC cross-linker. The NLS-ODNs decoy was transfected into HeLa cells by TransME transfection reagent. The intracellular distribution of fluorescent labeled NLS-ODNs decoy was detected with a microscope. The cell viability was detected by MTT assay, and then the activity of NF-kappaB in cell nuclear extract was assayed by electrophoretic mobility shift assay (EMSA). The results showed that NLS peptide was successfully conjugated to ODNs decoy by Sulfo-SMCC cross-linker. The NLS-ODNs decoy effectively entered into nucleus with high rate of 17.9%. It was observed that the cell viability of HeLa cell was not significantly affected by the transfection of NLS-ODNs decoy, while NLS-ODNs decoy significantly inhibited the activation of NF-kappaB in TNF-alpha induced HeLa cells nuclear extracts. This experiment can provide a new covalent conjugation of NLS peptide to ODNs can effectively drive decoy into nucleus, and thus improve its inhibitory effects on the activation a transcription factor.
