AlM:To compare the efficacy and complication of extra-trabeculotomy in combination with trabeculectomy and trabeculectomy and compound trabeculectomy in the treatment of primary infantile glaucoma.
METHODS: Patients with primary infantile glaucoma undergone one of the three procedures from Jan 2006 to Jan 2014 were selected. Among them, group A ( 20 patients, 31 eyes ) underwent extra- trabeculotomy in combination with trabeculectomy, group B ( 20 patients, 32 eyes ) underwent trabeculectomy, while group C ( 20 patients, 30 eyes) underwent compound trabeculectomyRESULTS:The success rates in group A were 96. 8% at the time of discharge and 90. 3% during follow-up (mean 24mo) ; the rates in group B were 96. 9% and 81. 2%( mean 24mo) the rates in group C were 83. 3% and 76. 7%( mean 24mo ) respectively, the differences being significant (P <0. 05). ln group A and group B, there was no severe complications, while in group C, one case had vitreous prolapse.
CONCLUSlON: Extra - trabeculotomy in combination with trabeculectomy is more efficacious and safer than trabeculectomy and compound trabeculectomy in the treatment of primary infantile glaucoma. lt should be the first choice for primary infantile glaucoma.

Objective To compare the prognoses in pregnancy women receiving routine perineal shaving and non perineal shaving before vaginal delivery through meta analysis.Methods The randomized controlled trials or non-randomized controlled trials for comparing the prognoses in pregnancy women receiving routine perineal shaving and non perineal shaving before vaginal delivery were retrieved from databases,including Cochrane Library,PubMed,EMbase,SCI,Ovid,CBM,Wanfang,VIP and CNKI,till December 2015.The studies were selected according to the inclusion and exclusion criteria,and the data were extracted and evaluated by two reviewers independently.The Meta-analysis was conducted via RevMan 5.2.6 software.Results A total of 6 studies (including three articles in English and three ones in Chinese) including 1 924 delivery women were included,1 083 cases in the perineal shaving group and 841 cases in the non perineal shaving group.No statistically significant difference was found in the incidence rate of fever after delivery between the perineal shaving group and the non perineal shaving group[Z=0.57,P=0.57,RR=1.14,95 ％ CI(0.73,1.76)],and there was no statistically significant difference in post-operative wound infection between the two groups [Z=0.43,P=0.66,RR=1.11,95％CI(0.69,1.78)].Conclusion Perineal shaving may be not an essential nursing intervention before vaginal delivery.

To assess the effect of prostaglandin E_1(PGE_1)on renal blood flow and serum endothelin of liver recipients.Methods PGE_1 was administered in 38 liver recipients at the dose of 0.6?g?kg~(-1)?h~(-1)during liver transplantation and every day after operation.The effects of PGE_1 on serum endothelin concentration and creatinine(Cr)were observed and these indexes were compared with those in the control group(n=18).The renal blood flow resistance indexes(RI)were measured by Doppler ultrasound.Results Cr and RI were significantly lower in PGE1=treated group than those in the control group.PGE_1-treated group also showed a significantly lower serum endothelin concen- tration.Conclusion Administration of PGE_1 in liver recipients can significantly improve the early re- nal function by reducing serum endothelin concentration and dilating renal blood vessels.

Immobilization conditions of Candida tropicalis to be absorbed in polyurethane foam carrier materials were studied on the xylitol production from corn hemicellulosic hydrolysate. Optimum batch-fermentation conditions were as follows: inoculum amount, 7% (volume ratio); polyurethane foam quantity, 1.0 g/100 mL; 30?C; initial pH, 6.0. Shaking speed was divided into two-phase to accommodate the dissolved oxygen, with 200 r/min at 0~24 h and 150 r/min at 24 h~46 h. The immobilized cells on polyurethane foam carrier have high density and good resistance to inhibitors in the hydrolysates. Average xylitol yield and volumetric productivity of polyurethane foam immobilized fermentation were much higher than the fermentation without immobilization. Corn cob hydrolysates can be directly biotransformed to xylitol without decoloration or ion-exchange treatment. This process can effectively reduce production costs, and it shows broad prospects of applications. Average xylitol yield was 67.6% and xylitol volumetric productivity was 1.92 g/(L?h).

ObjectiveTo explore the diagnostic methods and surgery pattern at the first time of spontaneous perforation of congenital choledochal cyst.MethodsEleven cases(4 male,7 female) with spontaneous perforation of congenital choledochal cyst were 6 months to 5 years old,and their average course of disease were 4 days.Gustily abdominal distension,abdominal pain,crying and fever were present in all cases.Jaundice(7 cases) and emesis(5 cases) appeared.All cases were detected with physical sign of peritonitis by physical examination.Choledochal cysts were confirmed by CT or B ultrasound in 8 cases.All cases accepted abdominal paracentesis and biliary ascites was drawn.Three different operative procedures were performed:choledochocyst excision & Roux-Y choledocho-jejunostomy(2 cases),choledochotomy with T-tube drainage(3 cases),and cholecystostomy(6 cases).Nine children receiving external drainage operation accepted a second operation to rebuild biliary tract(choledochocyst excision & Roux-Y choledochoje-junostomy) after 3 to 6 months.ResultsAll cases had got satisfactory therapeutic efficacy without any grave complication such as fistula of anastomotic stoma,infection of biliary tract or obstruction of biliary tract.During operation,perforations were located in the juncture of choledochus and cystic duct in 5 children and were not found in the other 6 children.In the second operation,the cases receiving cholecystostomy had less peritoneal adhesion,anatomic structure changes,haemorrhage[(30-50) mL vs(100-200) mL] and operation time[(2.5-3.0) h vs(3.5-5.0) h] than those receiving choledochotomy with T-tube drainage,and did not appear inadequate drainage for cystic duct obstruction.ConclusionsFor children with more organ inflammatory edema and adherence and in a bad overall condition,the first-time operation of cholecystostomy is more reasonable.

Objective To investigate celecoxib self-microemulsifying drug delivery system (CXB-SMEDDS) that was developed to increase the dissolution rate and oral bioavailability of celecoxib.Methods The formulation of CXB-SMEDDS was optimized by pseudo-ternary phase diagrams analysis.The appearance, morphology, particle size distribution and in vitro drug release behavior of CXB-SMEDDS were investigated after diluted by water.The bioavailability of CXB-SMEDDS was determined by oral administration to rats compared with CXB suspension.Results An optimized formulation was selected: Medium chain triglycerides as oil phase, Tween 20 as surfactant, Transcutol HP as cosurfactant.The ratio of oil phase, surfactant and cosurfactant was 2∶9∶9.Upon mixing with water, CXB-SMEDDS formed a clear and transparent microemulsion solution with homogeneous small spherical under transmission electron microscopy.For particle size of CXB-SMEDDS was found to be (57.6±14.2) nm.The in vitro dissolution test indicated a significant improvement in release characteristics of CXB.The AUC of CXB-SMEDDS and CXB suspension were (5.54±0.94) and (3.32±0.59) mg·L-1·h, respectively.The relative bioavailability was 166.9%.Conclusion The SMEDDS can significantly increase celecoxib dissolution in vitro and bioavailability in vivo.

Objective To detect the existence of vasculogenic mimicry in hepatocellular carcinoma (HCC). Methods In this study 42 patients with a total of 47 HCC nodules underwent radical resection.Histological and immunohistochemical double staining of CD31 and PAS were applied to observe the existence of vasculogenic mimicry ( VM ). Reverse tanscription PCR (RT-PCR) were applied to study the expression of VE-cadherin, EPHA2 and MMP-2 genes. Results VM was found in 16 of the 42 (38. 1% )HCC cases. The typical forms of VM in the microscope are vessel-like structure formed by tumor cells,without endothelial cells and the PAS-positive looping pattern. The existence of VM in HCC correlates to a higher Edmondson grade, higher capacity of intrahepatic disseminating and poorer tumor-free survival time (P＜ 0. 05). Comparing the difference of VE-cadherin gene, EPHA2 gene and MMP-2 gene expression between VM positive nodes and in VM negative nodes by RT-PCR method demonstrated that VE-cadherin gene, EPHA2 gene and MMP-2 gene have a more intense expression in VM positive nodes than in VM negative nodes ( P ＜ 0. 05 ). Conclusion VM exists in human hepatocellular carcinoma. VM occurred more frequently in higher malignant HCC and predicts a higher rate of tumor recurrence and poorer prognosis.
