Objective To discuss the effective surgical treatment of intrahepatic lithiasis combined with high hepa-t ic duct strictures. Methods Two hundreds and sixteen cases of intra hepatic lithiasis and high hepatic duct strictures treated in this hospital fr om January 1993 to October 2002 were analysed retrospectively.Results One hundred and eighty- three cases underwent different selective operation by selected time; 33 case s complicated with acute obstructive suppurative cholangitis underwent emergency were performed single biliary drainage, in which 30 cases were re-operated. Th e operative procedure were: hepatic lobectomy,high cholangiotomy and plastic repair,exposure of hepatic duct of the 2nd and the 3rd order,and plastic re pair with own patch and choledochojejunostomy.Two hundreds and six cases w ere cured,the curative rate was 95.4%; 8 cases improved (3.7 %), and 2 cases died (0.9%).Conclusion The best effective surgical treat ment of intrahpatic lithiasis is hepatic lobectomy. Exposure of hepatic duct of the 2nd and the 3rd order is a satisfactory to release the hepatic duct str ictures and to clear the intrahepatic lithiasis. For patients with normal extr ahepatic bile duct and Oddi's function, plastic repair of bile duct with own patch is possible to keep the normal form and function. Cholang ioscopy may play an important role in the treatment of intrahepatic tr act lithiasis during operation.

Objective To discuss the feasibility of stone removal in laparoscopic choledocholithotomy by routine laparotomic instruments. Methods A total of 73 patients with common bile duct stones were divided randomly into 2 groups: the Experimental Group received laparoscopic stone removal by routine laparotomic instruments; the Control Group received stone removal by choledochoscopic net-basket. The stone-free rate, operative time, total hospitalization costs and postoperative complications between the two groups were compared. Results There were no statistical significances in stone-free rate between the Experimental Group ( 94.4% , 34/36) and the Control Group (94.6%, 35/37) ( ? 2=0.000, P =1.000). The operative time in the Experimental Group (150.9 min?26.8 min) was shorter than that in the Control Group (172.3 min?28.6 min) ( t=3.297, P =0.002), whereas the total hospitalization costs in the Experimental Group (4400 yuan?1100 yuan) was lower than that in the Control Group (5000 yuan?1300 yuan) ( t=2.126, P= 0.037). No severe operation-related complications were observed in both of the groups. Conclusions Laparoscopic choledocholithotomy by either routine laparotomic instruments or choledochoscopy is safe and effective. Stone removal by routine laparotomic instruments has the advantages of low costs and short operative time.

Objective To investigate the effects of preoperative parecoxib on the levels of inter-leukin 6 (IL-6)and postoperative analgesia for breast surgery.Methods Sixty breast cancer patients undergoing mastectomy were randomly divided into two groups:parecoxib group (group P)and con-trol group (group C),n=30 in each group.All patients received sevoflurane and fentanyl anesthesia. Group P was injected parecoxib 40 mg at 10 minutes before induction of anesthesia,meanwhile group C was injected saline 5 ml.All patients received postoperative patient-controlled intravenous analgesia (PCIA)with fentanyl.VAS scores for pain were assessed at postoperative 2,4,8,12,24 hours. The serum levels of IL-6 were measured by ELISA at 10 minutes before induction,4 h,8 h,and 24 h after surgery.Results Group P had lower VAS scores than group C at 2-12 h after surgery (P <0.05).Compared with 10 minutes before induction,the levels of IL-6 increased significantly at post-operative 4,8,24 h in two groups (P<0.01),while group P had lower levels of IL-6 than group C (P <0.01).Conclusion Preoperative administration of parecoxib has a stronger analgesic effect in breast cancer patients after mastectomy,and decreases the levels of IL-6.

Objective To establish mathematical model for the differential diagnosis of endoscopic gastric ulcerative lesions with the help of image processing software and statistical analysis method. Methods The microscopic images of 25 gastric ulcers and 25 gastric peptic cancers were collected from January 2013 to December 2013.Then the Photoshop CS4 software was used for image processing and representative measurements gathering(area,perimeter,roundness,height,width,gray scale,involving the density,color,lightness,pixels).Then the principal component analysis,the scatter plot and cluster analysis were performed by SPSS 16.0.Results According to the results of principal component analysis, Z1 showed a strong positive correlation with area,perimeter,height,width,cumulative density,pixel,which represented the shape statistics of ulcer.And Z2 showed a strong positive correlation with gray scale,color, lightness,which represented the color statistics of ulcer.On the Scatter plot,gastric peptic cancer images showed a stronger positive correlation with the principal component Z1 and Z2 .Clustering analysis results showed that for the majority of patients,there was a pattern in its incidence.In the gastric ulcer diagnostic models,the effective information should include area≤10 000;perimeter≤250;height≤90;width≤60;gray scale≥90;cumulative density≤190 000;color≥110;and lightness≥110(unit:pixel).In the gastric ulcera-tive cancers,the effective information should include area≥38 000,perimeter≥690,height≥300,width ≥ 426,gray scale ≤ 100,cumulative density ≥ 14 000 000,color ≤ 125,and lightness ≤ 130 (unit:pixel). Conclusion Among the endoscopic image data,area,perimeter,roundness,height,width,gray scale, cumulative density,color,brightness,pixels are important indices,which can contribute to the differential diagnosis of gastric ulcerative lesions.The established mathematical model based on the ten indices can be applied to predict and diagnose gastric ulcerative lesions.

Objective To analyze the clinical results of 360° fusion for spondylolisthesis.Methods Data of 76 patients from March 2005 to November 2012,including 26 males and 50 females with a mean age of 54.3 years were retrospectively analyzed.All patients had undergone modified 360° fusion.The clinical outcomes were evaluated by the Japanese Orthopaedic Association scores (JOA) and visual analogue scale (VAS).The fusion status and loss of correction were assessed by CT and plain radiographs.Results All patients had been successfully followed up for at least one year.Post-operative reduction rate was 96.8％,with a mean loss rate of 1.1％ at six months and 0.8％ at one year follow-up separately,but the difference was not significant.Postoperative percentage of slip,lumbar lordosis,intervertebral disc height and slip angle had significant differences,compared with those of the pre-operative,but the difference between one week post-operative,six months follow-up and one year follow-up were not significant.The fusion rate was 76.3％ at six months follow-up and 98.7％ at one year follow-up,and there were significant differences.Both JOA and VAS score at six months and one year follow-up indicated significant differences in contrast to that of preoperative.Dural injury was found in one patient,and subsidence was found in one patient.One received a second operation at 3 months after the surgery due to screw loose.Conclusions Modified 360° fusion shows great clinical outcome and fusion rate,which can be a dominant procedure for treating spondylolisthesis.
