Objective To evaluate the efficacy of balloon dilatation in the treatment of intrahepatic biliary strictures in patients with liver transplantation. Methods Of the 100 patients with liver transplantation, 16 patients had intrahepatic biliary strictures and received balloon dilatation treatment. Results Initial technical balloon dilatation was successful in 14 cases but failed in 2 cases. There were no procedure-related complications. 4 restenosis occurred and they were treated with repeated balloon dilatation treatment. Conclusion Balloon dilatation represented an effective and relatively safe treatment for biliary stricture in liver transplant recipients. For restenosis, balloon dilatation was also an effective treatment.

Small for gestational age ( SGA ),one of the major adverse pregnancy outcomes, significantly increases the risk of perinatal death and metabolic diseases in adulthood. It is of great significance to strengthen early surveillance and intervention for SGA prevention. Dyslipidemia during pregnancy, as a common metabolic disorder, has been considered to correlate with the increased risk of SGA; however, the epidemiological evidence is still controversial. We have systematically reviewed the recent studies related to the association between serum lipid level during pregnancy and the risk of SGA, so as to provide reference for prevention and intervention of SGA.

Objective To evaluate the value of cholangiography for early diagnosis of ischemic-type biliary lasions(ITBL) after liver transplantation. Methods Two hundred and fifty-three patients with liver transplantaion between Jan 2004 and Oct 2006 were recruited. Initial cholangiography was compared with terminal cholangiography to evaluate the value of initial cholangiography of ITBL. The t test, Chi-square test, sum rank test were used for statistics. Results Based on initial cholangiography, 189 patients were diagnosed with normal appearance, while 64 patients were diagnosed with abnormal appearance. The abnormal initial cholangiography appearances included poor filling in 33 patients and irregularity in 31 patients. Based on terminal cholangiogruphy, 199 patients were diagnosed with normal appearance and 54 patients with ITBL In patients with abnormal initial cholangiography, ITBL was occurred in 39 of 64 patients including 10 of 33 poor frlling patients and 29 of 31 irregularity patients. In patients with normal initial appearance, ITBL was only occurred in 15 of 189 patients. The abnormal initial cholangiography was associated with ITBL significantly (X2 = 79.999, P = 0.000, r = 0.490). Initial cholangiography had an overall sensitivity of 72.22%, and specificity of 87.44%, with positive and negative predictive values of 60.94% and 92.06%, respectively. The abnormal initial cholangiogruphy was a risk factor of ITBL by logistic regression analyses(OR=15.193, P=0.000). Conclusion The abnormal initial cholangiography is associated with ITBL Initial cholangiography, especially minimal irregular of intrabepatic biliary tract, is a sensitive and specific method for the detection of ITBL after liver transplantation.

Kinematical alignment during total knee arthroplasty is an emerging process, and draws more and more attentions from scholars. Knee joint is close to normal joint after TKA through kinematical alighment, which has good clinical results and functional scores, and not increase failure probility. Thus, it may increase joint stress of patella-femur joint, lead to patellar maltracking and increase abrasion. The paper summarized defination and basical principle, operative method, clinical outcomes and deficiency of kinematical alignment during total knee arthroplasty, in order to choose a better way for kinematical alignment during total knee arthroplasty.

Objective To design and optimize the self-emulsifying drug delivery system ( SEDDS) of dihydromyricetin, and evaluate its quality in vitro. Methods The solubility of dihydromyricetin was measured in different oil phases,emulsifier and co-emulsifier solution. The best prescription was selected by comprehensively evaluating emulsification speed,particle size and drug loading via using the ternary phase diagram and orthogonal design test. Results The optimized formula of the self-emulsifying drug delivery system was oleic acidTween-80span-80N-butanol =1514714. Conclusion The optimized dihydromyricetin self-emulsifying drug delivery system significantly improves the solubility of dihydromyricetin, increases the physical and chemical properties of the formulation,and raises the dissolution of dihydromyricetin in artificial gastric fluid.

Objective To study the value of DSA for hepatic vascular anatomy,and to evaluate the efficacy of portal vein occlusion in rabbits with hepatic VX2 tumor.Methods Twenty New Zealand white rabbits were randomly divided into two groups with 10 in each group,including test group A and positive control group B of ham operation.For the test group A,portal branch ligation(PBL)was performed for the left external branch after 3 weeks of the tumor implantation to the left external lobe.Two weeks later,the DSA of hepatic artery and portal vein were performed in all of the rabbits.Results The total displaying effectiveness of the branches of hepatic artery by DSA was better than that by vascular perfusion.There was hypovascular blood supply to hepatic artery implantation of the tumor in the test group A,comparing with that of the group B.Conclusion DSA can clearly display spacial details of the hepatic vascular anatomy in rabbits,and play an important role in post-procedual evaluation of the portal vein occlusion in rabbits.

Fourteen compounds were isolated from the n-butanol fraction of the 95% aqueous ethanol extract of the stems and twigs of Strychnos cathayensis by D101 macroporous resin, silica gel, ODS, Sephadex LH-20 column chromatography, and semipreparative RP-HPLC. Their structures were elucidated as ethyl 4-O-β-D-allopyranosyl-vanillate (1), n-butyl 4-O-β-D-allopyranosyl-vanillate (2), n-butyl 4-O-(6′-O-syringoyl)-β-D-allopyranosyl-vanillate (3), n-butyl 4-O-(6′-O-vanilloyl)-β-D-allopyranosyl-vanillate (4), n-butyl 4-O-(6′-O-syringoyl)-β-D-glucopyranosyl-vanillate (5), n-butyl 4-O-α-L-rhamnopyranosyl-syringate (6), methyl 3-methoxy-4-(β-D-allopyranosyloxy) benzoate (7), pseudolaroside B (8), butyl syringate (9), glucosyringic acid (10), methyl syringate (11), methyl 4-hydroxy-3-methoxybenzoate (12), clemochinenoside C (13), and clemoarmanoside A (14), respectively, on the basis of spectroscopic data interpretation and by comparison with literature information. Compounds 1-6 are artificial products of phenolic acid esterified by ethanol or n-butanol. It is noted that the precursors (4-O-(6′-O-syringoyl)-β-D-allopyranosyl-vanillic acid and 4-O-(6′-O-vanilloyl)-β-D-allopyranosyl-vanillic acid) of compounds 3 and 4 are new compounds. The hepatoprotective, anti-inflammatory, antioxidant and cytotoxic activities of compounds 1-13 were evaluated in vitro at a concentration of 10 μmol·L^-1. Compounds 1, 2 and 6-10 exhibited potential hepatic protection effects with cell survival rates ranging from 53.6% to 55.5% (acetaminophen, 45.4% at 8 mmol·L^-1). Compound 4 demonstrated anti-inflammatory activity with nitric oxide inhibitory rate of 74.6%. Compounds 3 and 5 showed potential antioxidant activities with malondialdehyde inhibitory rates of 53.2% and 56.1%, respectively.
