Objective To investigate the clinical effects of endoscopic pancreatic duct stent insertion.Methods The clinical data of 20 cases of endoscopic pancreatic stent insertion,including 12 cases of chronic pancreatitis,3 cases of recurrent pancreatitis,2 cases of papilla adenoma after resection,3 cases of pancreatic carcinoma,was retrospectively reviewed from June 2004 to September 2006.All the patients underwent endoscopic pancreatic sphincterotomy and pancreatic stent insertion after endoscopic retrograde cholangiopancreatography(ERCP).Results All the 20 patients received 23 procedures of pancreatic stent insertion.Stent-preserving time was 25-105 days(mean,64.5 days).2 cases experienced stent migration and no postoperative pancreatitis occurred.20 patients were followed up for 6 to 12 months,including 17 patients for 12 months.During a follow-up period of 3 months in the 12 cases of chronic pancreatitis,1 case received repair because of duodenal perforation induced by ERCP,and the symptoms of abdominal pain or discomfort disappeared or were distinctively relieved in 9 and 2 cases,respectively,with weight gain 2-5 kg(mean,3.2 kg).A follow-up period of more than 3 months showed that the remission rate of abdominal pain was 92%(11/12).The jaundice was alleviated(with the average of decrease of 61.8 percent of total bilirubin in serum) and weight gained in the 3 cases of pancreatic carcinoma after the biliary and pancreatic duct plastic stents were inserted at the same time.Patients with recurrent pancreatitis had no relapse in the follow-up period.Conclusions The endoscopic pancreatic duct stent insertion is a safe and minimal invasive procedure,and can prevent postoperative pancreatitis,but the main complication of stent migration should be considered.

Objective Inflammation is considered as a driving force in the pathogenesis of Alzheimer's disease. We study the inhibitory effects of indomethacin on production of nitric oxide (NO) in ?-amyloid 1-42 stimulated microglia in vitro, in order to explore the role of ?-amyloid and microglia in the pathogenesis of Alzheimer's disease, and that admimistration of anti-inflammatory drugs might be an effective therapeutic modality. Methods We cultured murine microglia BV-2 cells to serve as the model of microglia for experimentation in vitro. Indomethacin in different concentrations (10 -9 , 10 -8 , 10 -7 , 10 -6 and 10 -5 mol/L) was added separately without or with ?-amyloid 1-42 20?mol/L, and culture was continued for 12h. The production of nitric oxide (NO) and the activity of inducible nitric oxide synthase (iNOS) in the supernatant of culture were determined. iNOS mRNA expression was assessed by RT-PCR. Results There was no effect in the production of NO and the activity of iNOS in BV-2 cells incubated with indomethacin alone. Indomethacin could inhibit NO production and lower iNOS activity and iNOS mRNA expression after microglia were stimulated by ?-amyloid 1-42, and the inhibitory effect was obvious at the concentration of 10 -7 -10 -5 mol/L. Conclusions As a conventional non-steroidal anti-inflammatory drug (NSAIDs), indomethacin can inhibit NO production, decrease iNOS activity and iNOS mRNA expression in BV-2 microglia after being stimulated by ?-amyloid 1-42 in vitro. The results suggest that the mechanism by which indomethacin might be beneficial in treatment of AD might be due to the inhibition of NO production from microglia, blocking the inflammatory cascade reaction to ameliorate injury to neuron. As an effective model in vitro, BV-2 microglia are valuable in the study of Alzheimer's disease.

[Objective] To evaluate the treatment effect of the synovial chondromatosis of the hip through arthroscopy,and to describe the arthroscopic classification.[Methods]From March 2001 to May 2008,21 patients underwent arthroscopic management for primary synovial chondromatosis of the hip.Of the 21 patients,15 were male and 6 were female,aged from 17 to 49 years.The disease was located on the left side in 9 patients,the right side in 12.Anterior and anteriolateral approaches were selected for synovectomy and removal of free bodies.The peripheral compartment received traction,and curved scraper and Slide Winder Blade(the bending radio frequency)were used to deal with the acetabular fossa.[Results]The range of motion of the hip was improved and the pain was released after operation.MRI showed hydrops articuli was reduced or vanished.Harris hip score for the series of patients improved from 56.2 points preoperatively to 92 points at the mean follow-up of 45 months(11 to 96).Of the 21 patients,18(85.7%)had excellent or good outcomes.No recurrent case was found.[Conclusion]Hip arthroscopy proved beneficial for patients diagnosed with synovial chondromatosis of the hip.It had the advantages of minimal invasion,quick recover and satisfactory outcomes.Arthroscopic classification may guide the procedure and avoid omision of the free bodies.
