Objective To investigate the effects of rosmarinic acid on the kidney function,urinary protein,serum MDA and SOD in rats with the 5/6 nephrectomy.Methods We established the rat model with chronic renal dysfunction and randomized them into normal control group,model control group and rosmarinic acid treatment group.There were 6 rats in each group.The blood creatinine level was recorded 2 weeks after operation.We detected the effects of rosmarinic acid on urinary protein,urine creatinine,blood creatinine,serum MDA and SOD in rats with the 5/6 nephretomy which was established by Ponseau S method.The treatment group received rosmarinic acid as an intervention.Results ( 1 ) Compared with control group,the creatinine and The creatinine clearance rate ( Ccr ) of rosmarinic acid treatment group increased ( F =38.912,P ＜ 0.01 ;F =19.968,P ＜ 0.05 ) after treatment,; (2) Rosmarinic acid improved the 24 h urine protein in rats with renal dysfunction significantly(F =16.288 P ＜0.01); (3) Rosmarinic acid had no effect on serum MDA and SOD in rats.Conclusion Rosmarinic acid can decrease urine protein and blood creatinine,increase the Ccr and alleviate kidney failure,but has no effects on MDA and SOD in rat model.

Objective To study the effeciency of endoscopic balloon dilat ation(EBD) for benign structures of colorectal anastomosis. Methods Fifteen cas es with benign stenosis of colorectal anastomosis(BCAS) were treated with endosc opic balloon dilatation,of which sigmoidectomy was performed in one case,and ant erior resection was performed in 14 case;stapler was used in 13 case,and hand su tura was used in 2 cases.Diameters and lengths of strictures were ranging from 0 .2～ 0.7 cm and 0.5～ 2.0 cm respectively. Results Strictures of all 15 patients were dilated successfully.There were no complications in this series.Follow－ u p has been from 3～ 30 months without recurrence of symptoms. Conclusion EBD is safe,efficient and well tolerated,and should be considered as the first choice o f treatment of BCAS.

Objective To improve the management of blunt pancreatic trauma, and to explore the strategy of preserving the pancreatic endocrine and exocrine function to the full extent. Methods 20 cases of blunt pancreatic trauma were reviewed and analyzed retrospectively. The methods of operative treatment were analysed. Results All patients were cured. Depending on the general condition, abnomial signs and main pancreatic duct(MPD) injuries at the time of admission, patients received immediate operation or nonoperative treatment. Because of severe peritonitis and demonstrated MPD injury, 10 patients underwent immediate operations, including simple drainage in 6 cases, distal pancreatectomy in 1 patient, external drainage of the injured pancreatic duct for the second operation in 3 cases. Without the demonstrated MPD injury or clinical deterioration, 10 patients received nonoperative treatment under strict observation initially. 3 patients completed the nonoperative course and 7 patients underwent delayed operations, including Roux-en-Y pancreatic cyst-jejunostomy in 3 cases, external drainage of pseudocyst in e cases, pancreaticoduodenectomy in 1 patient because of the expanded hematoma in pancreatic head. Conclusions Blunt pancreatic trauma could receive individual pancreas-preserving treatment, which could improve the operational safety, avoid the resection of pancreas and preserve the pancreatic endocrine and exocrine function to the full extent.

ObjectiveTo evaluate the clinical application of Kugel hernioplasty via anterior approach for inguinal hernia repair.MethodsA retrospective study was made to analyze the clinical data of 851 cases(956 hernias) treated with Kugel hernioplasty via anterior approach for inguinal hernias from November 2005 to May 2011.ResultsOperative duration was(42 ± 11) minutes.The postoperative complications were detected on 21 hernias of seroma,8 hernias of hematoma,12 hernias of sub dermal ecchymosis,26 hernias of foreign body sensation and 5 hernias of recurrence.No incision infection occurred.Conclusions Kugel hernioplasty via anterior approach can repair and strengthen the whole anatomy area of myopectineal orifice.It is available for various kinds of inguinal hernias.

Objective To investigate dynamic changes and clinical significance of the high-sensitive Creactive protein(hs-CRP) level in acute cerebral infarction patients with different etiological types.Methods 136 patients with acute cerebral infarction were recruited.These patients were classified into five subtypes based on Trial of Org 10172 in Acute Stroke Treatment(TOAST) criteria.Serum hs-CRP levels on the 1st,3rd,5th,7th,14th day after onset from patients and 42 healthy controls were measured with immunoturbidimetry.The neurologic impairmentscore was determined with NIHSS.Results Serum hs-CRP levels is higher on the 1th,3rd,5th,7th,14th day than that of the control group ( (4.26 ± 1.31 ),( 12.57 ± 6.29 ),( 10.23 ± 4.49 ),(7.54 ± 2.33 ),(4.25 ± 1.77) mg/Land (2.56 ± 0.86) mg/L,t = 7.89,10.26,10.99,13.55,5.97,P ＜ 0.05 ).Among 5 subtypes,serum hs-CRP was the highest in large-artery atherosclerosis group after acute ischemic stroke,and cardioembolism group was the next.Serum hs-CRP reached the highest on three or five days after disease onset and decreased slowly.High levels of hs-CRP in large-artery atherosclerosis group indicated severe neurologic functional impairment and worsen prognosis.Conclusions ACI is closely related to serum hs-CRP level,which can be used as an subjective index for severity and prognosis with the lasting,high levels of hs-CRP levels predict poor prognosis.

Objective To evaluate clinical application of Kngel patch in treating recurrent inguinal her-nia. Methods The clinical data of 65 patients with 77 sides recurrent inguinal hernia performed open preperitoneal inguinal hernia repairs from January 2005 to June 2009 were analyzed retrospectively. Kugel hernia patches were used in the operations. Results The operating time for unilateral hernia expended 40 ～ 150(76.5±20. 4) min. Postoperative pain was minimal and no incision infection appeared. The postopera-tive complications were 4 cases of uroschesis,6 cases of inguinoscrotal seroma, 2 cases of inguinoscrotal he-matoma and 3 cases of serotal hydrops. No serious complications such as sensation of foreign body, inguinal chronic pain and recurrence were observed during the follow-up of 3 to 54 months. Conclusions Open preperitoneal hernia repair with Kngel patch for adult recurrent inguinal hernia reparation is rational and fea-sible.

Objective To investigate the clinical efficacy of total pancreaticoduodenectomy for the pancreatic head adenocarcinoma with positive neck margin.Methods The clinical data of 15 patients with pancreatic head adenocarcinoma and had positive neck margin who received total pancreaticoduodenectomy at the Union Hospital of Fujian Medical University from August 2009 to May 2014 were retrospectively analyzed.Patients were followed up by out-patient examination or telephone interview till August 2014.Results Total pancreaticoduodenectomy was successfully carried out on the 15 patients.The operation time was 4.0-10.0 hours (mean,6.5 hours),and the volume of blood loss was 300-2 000 mL (mean,800 mL).The duration of postoperative hospital stay was 13.0-35.0 days (mean,22.3 days).The main postoperative complications included pulmonary infection (3 cases),abdominal infection (2 cases)and low blood glucose (2 cases).No interoperative death,bile leakage or gastrointestinal anastomotic fistula occurred.The blood glucose of most of the patients was controlled by insulin or pancreatin.No stomachache,steatorrhea or malnutrition occurred in all the patients.The mean time of postoperative follow-up was 21 months (range,3 months to 5 years).Three patients survived within 1 year,2 survived for 1-2 years,5 survived for more than 2 years and 1 survived for more than 5 years.Four patients with follow-up time under 6 months survived till now.Five patients had liver metastasis at postoperative month 6.Conclusion Total pancreaticoduodenectomy might be necessary for the pancreatic head adenocarcinoma with positive neck margin to achieve R0 resection.

Objective To investigate the correlation between disease severity and pleural effu sion in patients with acute pancreatitis(AP).Methods A retrospective analysis was conducted on a prospectively collected database.The demographic,clinical,and laboratory data of 246 consecutive cases of AP in patients admitted to the Affiliated Union Hospital of Fujian Medical University between January 2008 to December 2012 were reviewed.Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and computed tomography severity index (CTSI) were used to evaluate the disease severity of AP.The relationship between the severity and pleural effusion was analyzed.Receiver operator characteristic (ROC) curve was used to compare the values of APACHE Ⅱ score and CTSI in predicting the prognosis of patients with pleural effusion.Results Among the 246 patients,there were 184 patients with pleural effusion and 62 patients without pleural effusion.The incidence of pleu ral effusion in AP was 74.8％.Further study showed that the difference in the incidences of pleural effusion between the severe group and the mild group was significant (P＜0.01).There was a trend that the more serious the patient's condition,the more the pleural effusion.Moreover,the levels of pleural effusion were significantly and positively correlated with the APACHE Ⅱ score (r=0.775,P＜0.01) and CTSI (r=0.525,P＜0.05).Logistic regression analysis showed that the factors significantly associated with pleural effusion formation were a high APACHE Ⅱ score and a high CTSI.Areas under the ROC curve of the APACHE Ⅱ score,CTSI and combined assessment were 0.798,0.687 and 0.812 for predicting mortality of the patients with pleural effusion.Through comparison of the areas under the ROC curve,there was a significant difference between the APACHE Ⅱ score and CTSI as well as combined assessment and CTSI (P＜0.05).Conclusions The disease severity was closely related to pleural effusion in patients with AP.Combining the two scoring systems to evaluate the disease severity and providing active treatment were important to improve the prognosis of patients with pleural effusion.

1. 5 cm) sessile colorectal polyps referred for EMR. After submucosal injection of epinephrine, either en bloc or piecemeal snare polypectomy were performed. All resected specimens were retrieved for pathologic study. Follow-up colonoscopy was performed in all patients after EMR. Results All 157 polyps were removed completely. All lesions are larger than 1. 5cm, but 3 less than 1 cm on the submucosa of rectum. The largest one is 13 cm X 12 cm. No complication occurred. Histopathologic assessment of the resection specimens revealed the following: adenoma, 123; dysplasia, 80; mucosal carcinoma, 11; hyperplastic polyps, 20; rectal carcinoid, 3. Two patients who had rectal adenoma that was larger than 7cm recurrence happened at the resection site after 1 and 3 months follow-up respectively, than removed completely by hot biopsy forceps showed hyperplastic and villous adenoma on pathological study. No more residual tumor was detected for 6-12 months. Conclusion EMR with an intensive follow-up program is a safe and effective treatment for large sessile colorectal polyps and mucosal carcinoma.
