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.

Asteroid Hyalosis (AH) is a common clinical disease,which has been considered a benign disorder as it rarely impairs visual acuity.It was often discovered when the patient was treated for other eye diseases.The mechanism was unclear.Its characteristic B-ultrasound property makes the B-ultrasound a very helpful diagnostic technique.In the case of the patients with other fundus diseases associated with AH,optical coherence tomography (OCT) and fluorescein angiography (FA) may be used to reduce the interference from asteroid bodies,therefore improve the fundus visibility.Recent studies have shown that AH can incorporate with many other eye diseases.For example,in patients with cataracts,asteroid hyalosis can cause surface calcification of silicone plate intraocular lenses,which in most cases may lead to the need for explantation of the calcified intraocular lenses.The efficacy of pars plana vitrectomy (PPV),the removal of some,or all,of the eye`s vitreous humor for AH remains controversial.In this paper,we provide a review of the recent literature on AH disease: the etiology,diagnosis and treatment.We hope to thus improve the awareness and outcomes of AH disease.

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.

ObjectiveTo examine the effects of temsirolimus, an inhibitor of mammalian target of rapamycin, on bladder cancer cell lines T24 and BIU-87 in vitro and in vivo for purpose of evaluating the probability of mTOR targeted therapy for bladder cancer.MethodsAfter being treated by a different concentration of temsirolimus, T24 and BIU-87 cells were tested by MTT assay for cell proliferation activity.Cell cycle and apoptosis analysis were performed with flow cytometer. Wound scratch assay was used for cell migration activity and transwell motility assay. Western blot analysis was used to test the mTOR phosphorylation. Subcutaneous inoculation of 6-week-old nude mice was performed using 1 × 106 T24 cells in 50％ matrigel for both control (n = 10) and temsirolimus (n = 10) groups. The volume of tumors was examined and then the expression of Ki-67 was detected by immunohistochemistry.ResultsTemsirolimus significantly inhibited proliferation of T24 and BIU-87 cells in a dose- and time-dependent manner. After administration of temsirolimus on T24 and BIU-87 cell lines for 24 h, the rate of wound healing in 0 nmol/L groups were (88.9 ± 14. 1 ) ％ and ( 83.6 ± 16.3)％ , which were higher than in the 5 nmol/L groups, which were (42.7 ± 11.6) ％ and ( 36.9 ± 9.7 ) ％ ( P ＜ 0.05 ). In the transwell motility assay, the number of cells in the 0 nmol/L group was 26.5 ± 5.8 and 28.2 ± 4.6, which was higher than in the 5 nmol/L group ( 19.0 ±3. 8 and 21.3 ± 5.1, respectively) (P ＜ 0. 05). When temsirolimus was administered on T24 and BIU-87 cell lines for 48 h the percentages of cells delayed in phase G0/G1 in 5 nmol/L group were ( 77.46 ±6.11)％ and (73. 39 ± 4. 94)％ respectively, and higher than in the 0 nmol/L group, which were (65.99 ±5.01 )％ 、(60.15 ±3.98)％ (P ＜0.05). There was no statistically significant difference in the apoptosis rate between the two groups (P ＞ 0.05 ). In Western blot analysis, the ratios of p-mTOR/β-actin were 0.92 ±0.09 and 1.01 ± 0.08 in 0 nmol/L group, and higher than in the 5 nmol/L group (0.47 ±0.05、0.04 ±0. 01 ) (P ＜ 0.05 ). After administration of temsirolimus for 21 days, the tumor volume in nude mice in the control group were 351.1 ± 139.9 mm3 , which was larger than 351.1 ± 139.9 mm3 in the temsirolimus group ( P ＜ 0.05 ). The positive rate of Ki-67 expression was ( 67.3 ± 8.4 ) ％ in the control group, which was higher than in the temsirolimus group ( 35.5 ± 6.7 ) ％ ( P ＜ 0.05 ).ConclusionsThis study provides in vitro and in vivo evidence that temsirolimus may inhibit the viability of bladder cancer cells and temsirolimus could be exploited as a potential therapeutic strategy in bladder cancer.

ObjectiveTo study the differentiation of adipose tissue-derived mesenchymal stem cells (ADMSCs) into cardiomyocytes in vitro. MethodsADMSCs were isolated and purified by the method of digesting and adhering to the culture plastis. The third generation of cells were determined with immunocytochemistry method and induced by 5-aza. On the 7th, 14th, 21st, 28th day after being induced, the surface antigen of myoblast cell and cardiac myocyte were determined, the expression of gene of GATA4 and Nkx2.5 were tested, and the content of atrial natriuretic polypeptide (ANP) assayed. ResultsImmunocytochemical staining showed CD44, CD13, CD105 positive, CD45, CD34, HLA-DR, factor Ⅷ negative. After being induced by 5-aza, the direction of cell arraying was gradually similar. The cells were stained positively for Desmin, α-Sarcomeric Actin, myosin heavy chain and Troponin T. The cells express GATA4 and Nkx2.5 and secrete ANP. ConclusionThere was mesenchymal stem cells in human adipose tissue. 5-aza may induce ADMSCs to differentiate into cardiomyocytes in vitro.

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.

Secondary hyperparathyroidism is the most common complication of patients with chronic kidney disease.For patients poorly responding to medical treatment,parathyroidectomy would be the best choice.This article reviews the indications and modalities of surgical treatment for secondary hyperparathyroidism in patients with chronic kidney disease.
