20?g/L)prior to IPA embolization, and returned to normal after embolization. Conclusion Tumors located posteriorly and superticially in the liver may recruit blood supply though IPA collaterals. Phrenospasm should be cautious during IPA embolization.

Objective:To evaluate the effectiveness of procedure for prolapse and hemorrhoids(PPH) in the treatment of severe hemorrhoids.Methods:The experiment group(also called PPH group) consisting of 11 cases was subjected to PPH,the controlled group with 12 cases to Saresola-Klose method.Results:This study showed that the operating time and hospital stay after operation in PPH group were shorter than those in control group;less pain, less complication after operation and faster recovery were found in PPH group.Conclusion:PPH has such advantages as short operative time,less postoperative pain,fast recovery,less complications,etc.But its long-term curative effect is to be observed further.

Disability insurance is one of main component of isurance. This paper made comparison of disability standard of insurance among some countries and regions and drawn serveal chracteristics. With the review of Chinese Disability Standard for Insurance (1998 version),implications and strategies had been proposed for further revision.

The establishment of animal model is fundamental to the experimental studies. It involves the selection of animals and cell lines, the determination of the number of cells and the option of the ways of transplant. Only when each production step is operated by following the occurrence and the development mechanism of the gastric cancer, can we simulate the process of growth of the gastric cancer in human body.Due to their congenital immune deficiency, the nude mice serve a better choice for the establishment of gastric cancer animal model. Beyond that, the cell lines selection and transplant way option also play important roles.

Based on clues from the China CNKI database, 52 articles on Y in-Chen-Hao (YCH) decoction in the treatment of jaundice were screened. All modified YCH decoctions were taken. The ExcellPivotTable report and SPSS 19.0 factor analysis were used in the study of compatibility rules of YCH decoctions in the treatment of jaun-dice. The results showed that the prescription was mainly composed of heat-clearing drugs, water-dampness remov-ing drugs, drastic purgative drugs, which were combined with blood-activation and stasis-removing, qi-regulating drugs.

Objective To evaluate the prognostic value of combined analysis of the biomarker Krüppel-like factor 4 (KLF4) and the Milan criteria in hepatocellular carcinoma (HCC) patients treated by orthotopic liver transplantation (OLT).Method The clinicopathological data and outcome of the recruited 105 HCC patients undergoing OLT from October 2001 to April 2009 were retrospectively analyzed.KLF4 expression in HCC and paired non-tumor tissue was detected by immonohistochemistry and confirmed by Western blotting analysis.Five-year overall survival (OS) and recurrence-free survival (RFS) rate and survival curves of the grouped patients were calculated and plotted by Kaplan-Meier method.Result The level of KLF4 expression was lower in HCC than that in paired non-tumor tissue (P＜0.05).KLF4 expression was significantly lower in poorly differentiated HCC than that in well-moderately differentiated HCC (P =0.008).Loss of KLF4 was an independent risk factor for predicting tumor recurrence and survival of HCC after OLT (HR =0.459 and 5.42,respectively,P＜0.001).The level of KLF4 expression could not differentiate the OS and RFS rate in the patients with tumors meeting the Milan criteria,whereas the OS and RFS rate in the patients with tumors exceeding the Milan criteria differentiated according to KLF4 expression.The patients with tumors beyond the Milan criteria and exhibiting moderate to high KLF4 expression had unexpectedly favorable 5-year OS (91.7％) and RFS (70.5％) rate.Conclusion KLF4 is a useful biomarker for prognostication of HCC patients undergoing OLT.Integrated use of KLF4 biomarker and the Milan criteria improves accurate prediction of survival and tumor recurrence for HCC patients after OLT.

Curcumin is a principal polyphenolic curcuminoid extracted from turmeric rhizome, which has been used for treating inflammation of joints, ulcers, jaundice and other disorders in Asian traditional medicine. In recent years, many studies have indicated that curcumin plays important roles in treatment of liver diseases. Curcumin attenuates liver injury and non-alcoholic fatty liver disease by lowering the release of inflammation cytokines, minimizing oxidative stress, enhancing the sensitivity of insulin and altering lipid metabolism. Curcumin shows potent anti-fibrosis activity, contributing to inhibit the activation of hepatic stellate cells and reduce the deposition of extracellular matrix by its regulation of PPAR-γ, NF-ΚB and TGF-β signaling pathways. Moreover, curcumin exhibits anti-cancer effect by inducing G2/M phase cell cycle arrest and apoptosis in several hepatoma cell lines. However, poor water solubility and low bioavailability of curcumin limit its clinical applications. To overcome its limited systemic bioavailability, many new approaches have been explored to deliver curcumin effectively. This article focuses on advances in the effects of curcumin and its derivatives for treatment of liver injury, non-alcoholic fatty liver disease, liver fibrosis and hepatocarcinoma.

Liver transplantation (LT) is one of the most important curative treatment for hepatocellular carcinoma (HCC).In the past decade,great achievements have been made in the field of liver transplantation in China.The incidence of postoperative complications and hospital mortality have significantly decreased due to growing experience and maturity of surgical techniques.However,tumor relapse after LT still negatively impact on the long-term outcome of patients with HCC.HCC recurrence and patients' survival after LT are closely related to preoperative screening of patients,listing priority,local treatment and postoperative management.Successful management of these procedures determines the final therapeutic effect of LT on patients with HCC.In this article,the above issues were explored and discussed according to the current situation of domestic transplant community through revision of the literatures in combination with the clinical experiences.

Based on the superior optical properties and the advantage of surface-modifiable capacity,the novel fluorescent nanoparticle quantum dots can conjugate with many kinds of biomolecules or chemical materials to form target quantum dots,which play an important role in biomedicine.The target ability this probe possesses offers a more accurate tumor localization,and minimizes the side effect to normal cells while strengthens the curative effect.At present,the probe makes a great progress in many areas,such as cell and molecule recognition,imaging in vivo,biosensing and diseases treating.

Objective To explore the curative effect of ursodeoxycholic acid in treatment of intrahepatic cholestasis of pregnancy (ICP) and the effect on total bile acid (TBA) in post partum fetal umbilical venous blood .Methods 30 patients with intrahepatic cholestasis of pregnancy who were admitted into the Hospital Affiliated to Sichuan Medical University during January 2014 to December 2014 were selected as the research objects and randomly divided into observation group and control group ,15 cases in each group.The observation group were given ursodeoxycholic acid tablets while control group were injected with ademetionine butanedisulfonate .The curative effect of two kinds of drugs in treatment of intrahepatic cholestasis of pregnancy was observed and the effect on total bile acid in post partum fetal umbilical venous blood was analyzed .ResuIts After treatment , the TBA and ALT of observation group were significantly lower than those pre-treatment and those of control group (P<0.05).There were no significant differences of TBIL and ALP between two groups and within groups.TBA and TBIL in post partum fetal umbilical venous blood of observation group were significantly lower than those of control group (P<0.05).There was no significant difference of ALT level between two groups .There were two cases of abnormal perinatal outcomes in observation group while seven cases in control group (χ2 =3.97, P<0.05).ConcIusion Ursodeoxycholic acid could effectively reduce the total bile acid levels in maternal and fetal umbilical vein blood, reduce the mortality rate of the fetal and improve the perinatal outcomes , with high security.
