Objective To evaluate the clinical effect of ultrasound-guided percutaneous transhepatic cholangial drainage (PTCD) combined with endoscopic retrograde cholangio-pancreatography (ERCP) in treating malignant obstructive jaundice, and to discuss its technical points. Methods A total of ten cases with malignant biliary obstruction were enrolled in this study. After the failure of ERCP treatment, the patients had to be treated with ultrasound-guided PTCD immediately. The guide-wire was inserted into the duodenum through intrahepatic bile duct and common bile duct to connect with ERCP, which was followed by the biliary stent implantation or the removal of physical factors causing obstruction. The clinical results were analyzed. Results Technical success was obtained in all 10 cases. In the patients who underwent a successful guide-wire docking with ERCP the postoperative serum bilirubin was significantly decreased. The main complications were fever, elevation of amylase and transient bloody bile. Conclusion With the help of docking technique the combination use of ultrasound-guided PTCD and ERCP is a new tentative treatment for malignant obstructive jaundice after the failure of initial ERCP treatment. This technique carries promising value in clinical practice as it can significantly increase the success rate of ERCP.

This study is performed to analyze the anti-liver fibrosis effect of the fusion protein of human serum albumin and extracellular domain of transforming growth factor beta type II receptor(eTGFBR2)in vivo to looking for the more stable anti-liver fibrosis drug. The mice model of liver fibrosis was constructed by CCl4 induction and the following groups are included in the study: the control group, CCl4 model group, the positive control group, eTGFBR2 treatment group, HSA-eTGFBR2 treatment group, and HSA group. Hematoxylin eosin staining, serum liver function index detection, and western blot are used to identify the anti-liver fibrosis activities. The results showed that: (1)CCl4 caused liver structure disorder, hepatocellular necrosis, collagen fibers proliferation, and induced liver fibrosis at last; (2)HSA-eTGFBR2 and its monomer drug improved the symptoms of liver fibrosis significantly, as well as reduced the damage of liver cells and collagen deposition, and recovered the liver basic structure to normal. Both of HSA-eTGFBR2 and its monomer drug improved liver function and reduced the expression level of liver fibrosis marker α-SMA and COL I. Moreover, the anti-liver fibrosis effect of the fusion protein is comparable to the monomer drug. In contrast, the albumin had no effect on therapeutic effect; (3)Reducing the injection frequency of HSA-eTGFBR2 achieved the comparable effects to the monomer drug with the normal injection frequency. In summary, the fusion protein HSA-eTGFBR2 has good anti-liver fibrosis effect. In addition, reducing the injection frequency of the fusion protein could also achieve the comparable treatment with the monomer drug, indicating that the fusion protein is stable and has longer half-lives and then a relatively positive application prospect in future.

Objective Based on detection of the soluble LAIR-1 (sLAIR-1) and sIL-2R in the bile from recipient after liver transplant, the role of sLAIR-1 and sIL-2R in graft acute rejection were analyzed. Methods Bile sLAIR-1 level and sIL-2R were determined by double mAb sandwich enzyme linked immunosorbent assay in 55 cases of liver transplantation. Results In 22 recipients with normal graft function, sLAIR-1 and sIL-2R were detected at low level in the bile. In the 29 cases of liver acute rejection (AR), significant increase of bile sIL-2R level was detected on the lst and 2nd d before final diagnosis. With the effective methylprednisolone pulse therapy, sIL-2R level was decreased significantly on the 3rd d. On the other hand, remarkable increase of bile sLAIR-1 was found on the lst,2nd and 3rd d before final diagnosis. After of methylprednisolone pulse therapy for 3 d, bile sLAIR-1resturned to the control level. Conclusion Both bile sIL-2R and sLAIR-1 are detected at high level in the recipients suffering from liver acute rejection. The level of bile sLAIR-1 changes dramatically and responsively according to liver acute rejection. Therefore, detecting these two markers synergistically may be a promising monitor for rejection after liver transplantation.

Background Presbyopia is one of primary causes affecting the visual and life qualities of the agings,and its mechanism is associated with the oxidative damage of lens epithelial cells with ageing.SS31 is a mitochondria-targeted antioxidant peptide.To study the effect of SS31 on oxidative damage of lens epithelial cells has an important significance for the prevention and treatment of presbyopia.Objective This study was to investigate the effect of SS31 on in vitro oxidative damaged human lens epithelial cells.Methods Human lens epithelial cell line (HLEB-3) was cultured using DMEM with low glucose and 10％ fetal bovine serum(FBS).The cell model of oxidative damage was established by adding 200 μmol/L tea-butyl hydropeoxide (t-BHP) into DMEM for 18 hours.The cells were divided into blank control group,t-BHP model group,10 nmol/L SS31 +t-BHP group,100 nmol/L SS31 +t-BHP group,1 μmol/L SS31 +t-BHP group,10 μmol/L SS31 +t-BHP group and 100 pμmol/L t-BHP group,and then MTT assay was used to detect the survival rate of the cells and evaluate the optimal SS31 concentration for sequential study.The cells then were divided into blank control group,t-BHP model group and 1 μmol/L SS31 +t-BHP co-culture group.The change of mitochondrial membrane potential of the cells was tested by JC-1 dye and flow cytometry.Reactive oxygen species (ROS) level in the mitochondria was determined using MitoSOX staining.Results The cell survival rate in the t-BHP model group was (53.42±2.52)％,and that in the blank control group was 100％.The cell survival rate was considerably increased in various concentrations of SS31 groups,showing a significant difference among different groups (F=58.349,P＜0.01).A highest survival rate was (82.13 ±3.15) ％ in the 1 μmol/L SS31 +t-BHP co-culture group,which was statistically significant in comparison with the t-BHP model group (t =28.710,P＜0.05).JC-1 dye and flow cytometry assay showed that the ratio between red and green fluorescence intensity was 7.07 ±0.06 in the blank control group,4.46±0.14 in the t-BHP model group and 5.76±0.26 in the 1 μmol/L SS31 +tBHP co-culture group,showing significant difference among the 3 groups (F=172.332,P＜0.01).The ratios between red and green fluorescence intensity in the blank control group and 1 μmol/L SS31 +t-BHP co-culture group were higher than that in the t-BHP model (t =2.609,1.303,both at P＜0.001).ROS fluorescence cells were much more in the t-BHP model group compared with blank control group and 1 μmol/L SS31 + t-BHP co-culture group.Conclusions SS31 can protect HLEB-3 cells from oxidative stress.SS31 may serve as a potential new approach to the treatment of presbyopia and other age-related diseases of lens.

Objective To investigate the role of soluble CD305(sCD305)in renal allograft rejection.Methods Concentration of serum sCD305 was detected on 20 healthy volunteers and 153 cases of recipients after kidney transplantation by using double monoclonal antibody sandwich enzyme linked immunosorbent assay.Results In the healthy volunteers and 98 recipients with normal renal funetion,sCD305 was detected at low levels of(4.3±2.3)μg/L and(6.3±3.7)μg/L.In 20 cases of acute rejection and 5 cases of graft loss,serum sCD305 levels were(36.3±14.7)μg/L and(28.8±9.4)μg/L,and significantly higher than those in the healthy volunteers and recipients with normal renal function.Meanwhile,in the 30 cases of chronic rejection and 6 cases under dialysis treatment,the levels of sCD205were(13.1±5.5)ttg/L and(11.2±4.6)μg/L and significantly higher than those in the healthy volunteers and recipients with normal renal function.Conclusions CD305 was presented at high level in the recipients with renal acute or chronic rejection,and it might be a potential marker for monitoring graft rejection after transplantation.

Objective To investigate the relationship between the soluble LAIR-1(sLAIR-1)in the serum from recipients after transplant and graft rejection.Methods Serum sLAIR-1 level was determined by double mAb sandwich enzyme linked immunosorbent assay on 23 cases of liver transplantation and 139 cases of kidney transplantation.Results In healthy volunteers and 98 recipients with normal graft function,sLAIR-1 was detected at low level [(4.3±2.3)μg/L and(6.3±3.7)μg/L],with the difference being not significant.In 6 cases of liver acute rejection,20 cases of kidney acute rejection and 5 cases of graft loss,serum sLAIR-1 levels were increased remarkably at high 1evels [(47.2±25.9)μg/L,(36.3±14.7)μg/L,and(28.8±9.4)μg/L respectively]as compared with the two groups of healthy volunteers and the recipients with normal graft function,even peaked at 117.3 μg/L in one case of severe liver rejection.Meanwhile,in 5 cases of liver chronic rejection,27 cases of kidney chronic rejection and 6 cases under dialysis treatment.the levels of sLAIR-1 were(16.1±6.4)μg/L,(13.1±5.5)μg/L and(11.2±4.6)μg/L respectively,significantly higher than those of the healthy volunteers and the recipients with normal graft function.Conclusion sLAIR_1 was detected at high level in the recipients suffered graft acute or chronic rejection and might be a promising monitor of rejection after transplantation.

Objective To investigate sequence variations of 12 miRNA genes in multiple myeloma(MM) in order to find whether sequence variations in miRNA genes are associated with tumorigenesis and discuss the clinical significance of MM associated with miRNA genes mutations. Methods The miRNA gene mutations in 20 cases of MM, 4 MM-derived cell lines and 20 controls were detected by the methods of polymerase chain reaction single stranded conformation polymorphism (PCR-SSCP) and silver staining technique. Both clinical features and laboratory results were analyzed simultaneously. Results The electrophoretic patterns showed a total of three variations in miR-19a, miR-19b and miRNA-335,which were observed in 3 MM cells (15 %, 3/20). We also found variations of miRNA-335 in MM-derived cell lines KM-3and RPMI8226. However, no sequence alteration in the miRNA genes was observed in our set of controls. One of the three MM patients died, and two of them were detected mutations at the terminal stage of the disease.Conclusion A relative high frequency of miRNA gene mutation was found in MM and MM derived cell lines, which suggests possibility of a main mechanism underlying tumorigenesis. And, detecting miRNA gene mutations in MM might be benefit to evaluate the progression and prognosis of disease.

This study was focus on investigating the anti-liver fibrosis effects of insulin-like growth factor-1 (IGF-1) in vitro.The effects of IGF-1 on human liver L-02 cell viability and cell cycle were observed.CC14-induced L-02 cell injury was set up to detect the anti-apoptotic activity of insulin-like growth factor-1 (IGF-1).Transforming growth factor β1 (TGF-β1) induced hepatic stellate cell line (HSC-T6) were used as a liver fibrosis model in vitro to analyze the effects of IGF-1 on the expression of liver fibrosis proteins and intracellular TGF-β1/Smad signaling pathway in HSC-T6 cells.The results showed that IGF-1 could relieve the growth inhibition effects of TGF-β1 on L-02 cells,increase the viability of L-02 cells injured by CCl4,decrease the expression of liver fibrosis proteins,and inhibit the TGF-β1/Smad signaling pathway by inhibiting the phosphorylation of Smad3.Our study suggested that IGF-1 exerted anti-liver fibrosis effects by stimulating L-02 cells proliferation,reducing cell damage and inhibiting ECM accumulation via interfering TGF-β1/Smad signaling pathway.
