MethodsFrom July 2008 to September 2011,intraoperative extra strong electrical stimulation was applied in 9 cases of incomplete birth brachial plexus palsy after neurolysis.The latency and amplitude of compound muscle action potentials before and after electrical stimulation were recorded and the extent of improvement was compare.ResultsThe latency was improved in 7 cases with 8.02％ in average,amplitude in 8 cases with 185.97％ in average.The related nerve recover partial motor function in 8 cases in 2 weeks after operation.ConclusionIntraoperative extra strong electrical stimulation is a effective assistant technique to promote motor functional recovery of birth brachial plexus palsy.

Objective To observe the application effect of the risk of ovarian malignancy algorithm(ROMA)in screening ovarian cancer among high risk population.Methods The human epididymis protein 4(HE4)and carbohydrate antigen 125 (CA125 )were detected in 1 753 cases of high risk for overian cancer,56 cases of ovarian cancer(positive control)and 60 healthy people,patients. Then the ROMA value was calculated in combination with the subject′s menstruation status.The detection results were analyzed and compared among groups.The high risk group for ovarian cancer devided according to the ROMA value was further performed the confirmatory test and the low risk group was monitored by follow up.The detection rates of ovarian cancer were compared be-tween the two subgroups.Results In the high risk population,the diagnostic performance of the ROMA value for ovarian cancer was superior to that of the single HE4 or CA125;the ROMA value had statistically significant difference between the high risk sub-group in the high-risk population with ovarian cancer or the healthy control group(P <0.05);in 1 753 cases of high risk popula-tion,37 cases were included in the high risk subgroup,in which 3 cases of ovarian cancer were screened out and in clinical early stage.The detection rate of ovarian cancer in the high risk subgroup was 8.1%.No case of ovarian cancer was detected out in the low risk subgroup.Conclusion The ROMA value is conducive to early screening for ovarian cancer in the high risk population, which can save the medical cost and increase the detection rate.

ObjectiveTo explore the efficacy and safety of percutaneous antegrade stenting in the treatment of ureteral obstruction after renal transplantation.MethodsWe retrospectively reviewed 11patients with renal graft ureteral obstruction (2 cases of acute obstruction and 9 cases of chronic obstruction) from March 2009 to March 2011.The etiology of the obstruction was renal graft-ureter-bladder anastomotic stricture in 5 cases,stone obstruction in 2 cases,and undetermined in 4 cases.Renal graft and collecting system were examined by ultrasonography preoperatively to select suitable puncture position,and then ureteropyelography was performed under X-ray guidance.When the obstruction location was clear,the urology guidewire was implanted to the bladder by needle,and then guidewire was released by cystoscopy.Ureteral stent was implanted along the guidewire,and upper ureteral stents was observed under X-ray. After removal of guidewire,the stent location was confirmed once again.The renal pelvis fistula drainage lasted for 1-2 weeks,and ureteral stent to 6 months to one year.Ultrasound and renal function were tested after 1week,1month,3 months and 6 months,and then every six months.ResultsOperation was done successfully in 10 patients,and failed in one case due to a long segment of ureteral stenosis.The operating time of ureteral stent implantation was 54±27 min.Serum creatinine of patients was reduced from preoperative 326±147 to postoperative 89±49 μmol/L.During a follow-up period of 6 to 27 months,no complications occurred.ConclusionPercutaneous antegrade stenting in the treatment of ureteral obstruction after renal transplantation is safe and effective.

AIM: To explore the neuroprotective action of progesterone(PROG), which has been proved to be a "neuroactive steroid". METHODS: The model of focal cerebral ischemia was established in rats by reverserble inserting a nylon thread with a diameter of 0.2 mm into the anterior cerebral artery through the internal carotid artery. The effect of PROG was assessed by determining water,sodium, potassium, and calcium contents in striatum of rats subjected to 2 h ischemia followed by 22 h reperfusion. RESULTS: The water,sodium,and calcium contents of middle cerebral artery occlusion(MCAO) striatum were obviously higher,the potassium content was obviously lower than those of non-MCAO striatum in I/R and DMSO groups,but there was no significant difference between these two groups.Compared with the result in I/R and DMSO groups , water, sodium and calcium contents significantly decreased, but potassium(P0.05). CONCLUSION: Treatment with PROG can significantly reduce the striatal injury of rats with cerebral ischmia-reperfusion.

Objective To investigate the method to isolate and culture hepatic stellate cells ( HSCs) for studying the cellular mechanisms of hepatic frbrosis.Methods HSCs were isolated by nycodenz density gradient centrifugation after the hepatocytes obtained from adult male gebils were digested with pronase, collagenase and DNase, infused via portal vein.The cell viability was determined by trypan blue exclusion test.The purity of HSCs was identified by detectingα-SMA, desmin immunohistochemical staining.Results The yield rate of HSCs was 0.5~1 ×107 per gerbil liver, and the cell viability was more than 90%.The percentage ofα-SMA-positive cells was more than 75%after 3 days primary culture and almost 100% cells were α-SMA and desmin positive in passage culture.Conclusion The successful protocol of primary culture of Mongolian gerbil HSC provide a technical support for research of relevant liver diseases and drug development in the future.
