Objective To investigate the level of soluble interleukin 7 receptor (sIL-7R) in serum of lupus nephritis(LN)patients and evaluate its clinical significance. Methods sIL-7R level in serum of LN patients and healthy controls were measured by ELISA , while total 24 hours urinary protein and complement C3 of LN patients were measured by BN ProSpec. The level of sIL-7R correlation with SLEDAI, total 24 hours urinary protein and complement C3 were analyzed respectively. Results The levelof sIL-7R was higher in serum of LN patients than healthy controls (P < 0.01). Moreover, its expression in serum was increased in LN patients in active stage than in LN patients in stable stage (P < 0.05). The level of sIL-7R was positively assosicated with SLEDAI, total 24 hours urinary protein(P < 0.01, P < 0.05) and negatively with complement C3 (P < 0.05). Conclusion The level of sIL-7R is upregulated in serum in LN patients and correlated with disease activity and progression, so it may be expected to become a potential marker of disease in prediction.

Objective:To analyze the change rules of quantitative parameters of magnetic resonance-perfusion weighted imaging (MR-PWI) in cynomolgus monkeys with different degrees of liver fibrosis, and to explore the best parameter of MR-PWI in evaluating the severity of liver fibrosis.Methods:Liver fibrosis models of twenty-two cynomolgus monkeys were successfully established by subcutaneous injection of carbon tetrachloride and feeding with high-fat food. Among them, 15 cynomolgus monkeys developed into early liver cirrhosis (stage S4 of liver fibrosis). Compatibility group design was adopted, the comparative study on MR-PWI of exchange double blood supply model of liver was carried out in these 15 cynomolgus monkeys with a complete development process of liver fibrosis. The quantitative parameters of MR-PWI included endothelial transfer constant ( ktrans), reflux rate constant ( kep), extravascular extracellular space fractional volume ( ve), fractional plasma volume ( vp) and hepatic artery perfusion index (HPI). The change rules of the above parameters and their correlation with the severity of hepatic fibrosis were analyzed. The best parameter of MR-PWI was explored. Compatibility group design (randomized block design), analysis of variance, SNK- q test, Spearman rank correlation analysis and receiver operating characteristic (ROC) curve analysis were used for statistical analysis. Results:ktrans and kep of MR-PWI of cynomolgus monkeys decreased along with the progress of hepatic fibrosis, and the differences were statistically significant ( F=685.228, 99.718, both P<0.01). There were statistically significant differences between each stage of hepatic fibrosis (S1 to S4) and normal liver tissue (S0) ((0.527±0.038), (0.479±0.035), (0.432±0.032) and (0.387±0.031) mL/min vs.(0.584±0.044) mL/min, all P<0.01; (2.193±0.307), (1.997±0.301), (1.624±0.174) and (1.532±0.130) mL/min vs. (2.565±0.482) mL/min, all P<0.01). There were statistically significant in ktrans and kep between stage S3, S4 severe liver fibrosis and stage S1 mild liver fibrosis, stage S2 moderate liver fibrosis (all P<0.01), however there were no statistically significant differences between stage S3 and stage S4 liver fibrosis, between stage S1 and stage S2 liver fibrosis (all P>0.05). Along with the development of the severity of liver fibrosis, HPIs increased gradually, and the differences were statistically significant ( F=839.883, P<0.01). The HPIs of stage S0 to S4 were 0.244±0.022, 0.317±0.035, 0.421±0.046, 0.546±0.043 and 0.651±0.058, respectively, and there were statistically significant differences between groups (all P<0.01). Along with the progression of the severity of liver fibrosis, vp decreased while ve increased gradually, but there were no statistically significant differences among groups (all P>0.05). The results of Spearman rank correlation analysis indicated that ktrans and kep were negatively correlated with the severity of liver fibrosis ( rs=-0.875 and -0.797, both P<0.01), however HPI was positively correlated with the severity of liver fibrosis ( rs=0.959, P<0.01). The results of ROC curve analysis showed that area under curves (AUCs) of ktrans, kep and HPI in the diagnosis of early cirrhosis were 0.852 (95% CI 0.767 to 0.937), 0.799 (95% CI 0.700 to 0.897) and 0.967 (95% CI 0.932 to 1.002), respectively. The best cut-off values were 0.395 mL/min, 1.561 mL/min and 0.590, respectively. The sensitivity was 86.7%, 79.6% and 97.4%, respectively and the specificity was 77.4%, 71.9% and 93.1%, respectively. The thresholds of HPI in the diagnosis of liver fibrosis at stage S1, stage S2, stage S3 and stage S4 were 0.291, 0.376, 0.503 and 0.590, respectively; the sensitivity was 95.7%, 93.8% and 94.4% and 97.4%, respectively and the specificity was 89.5%, 84.7%, 91.3% and 92.7%, respectively. Conclusions:The parameters of MR-PWI change regularly with the development of liver fibrosis in the cynomolgus monkey model, among which HPI is the best parameter for quantitative evaluation of the severity of liver fibrosis.

A novel series of benzyl urea analogues based on the structural modification of sorafenib were synthesized. Their in vitro antitumor activities against MX-1, HepG2, Ketr3 and HT-29 were evaluated using the standard MTT assay. While several target compounds showed inhibitory activity against multiple cancer cell lines, compound 9 was of particular interest, demonstrating IC50 values (5.69-13.6 micromol x L(-1)) comparable to those of sorafenib. Furthermore, compounds 20 and 23 showed more potent inhibitory activity against HT-29 and MX-1 when compared to sorafenib. In particular, compound 20 bearing the N-3-pyridyl moiety not only exhibited greater inhibitory activity against HT-29 cell line (IC50 3.82 micromol x L(-1)), but also had improved solubility at pH 7.2, is worthy of further investigation as a lead to identify novel antitumor agents.

Objective:To study the efficacy and safety of Hassab operation combined with either radiofrequency ablation(RFA) or liver resection in treatment of liver cancer associated with portal hypertension.Methods:A retrospective analysis was conducted on the clinical data of patients with primary liver cancer associated with portal hypertension operated at the Department of General Surgery of Beijing Ditan Hospital from June 2013 to June 2015. These patients were divided into the RFA combined with Hassab operation group and the liver resection combined with Hassab operation group according to the surgical procedures. The general patient information, operation time, intraoperative blood loss, intraoperative blood transfusion, postoperative hospital stay, postoperative complications and the 1-, 3-, and 5-years cumulative survival rates and recurrence-free survival rates were compared.Results:Of 53 patients who were included in the study, 30 patients were in the RFA combined with Hassab operation group (including 28 males and 2 females, average age 46.3 (27.0~64.0) years, and 23 patients in the liver resection combined with Hassab operation group (including 20 males and 3 females), average age 44.7(33.0~59.0) years. There were no significant differences in the general patient information including age, gender, maximum tumor diameter, preoperative laboratory tests (including blood routine, liver function, tumor markers), and Child-Pugh classification between the two groups (all P>0.05). Intraoperative blood loss in the RFA combined with Hassab operation group was significantly less than those in the liver resection combined with Hassab operation group [(401.67±183.12) ml vs (552.17±333.88) ml, P<0.05]. There were also no significant differences between the two groups in operation time, blood transfusion during operation, postoperative hospital stay, and postoperative complications ( P>0.05). The incidence of severe postoperative complications (Clavein-Dindo grade ≥ IIIb) in the liver resection combined with Hassab operation group was 47.8% (11/23), which was significantly higher than the 20.0% (6/30) in the RFA combined with Hassab operation group ( P<0.05). The 1-, 3-, and 5-year cumulative survival rates of patients in the RFA combined with Hassab operation group were 82.8%, 49.9%, and 33.2%, respectively, while the corresponding survival rates of patients in the liver resection combined with Hassab operation group were 81.0%, 58.2%, 43.7%, respectively. There was no significant difference between the two groups ( P>0.05). The recurrence-free survival rates of patients in the RFA combined with Hassab operation group at 1-, 3-, and 5-years after surgery were 79.2%, 38.8%, and 21.6%, respectively. The corresponding recurrence-free survival rates of patients in the liver resection combined with Hassab operation group were 76.4%, 41.7%, and 27.8%, respectively, and there was no significant difference between the two groups ( P>0.05). Conclusion:RFA combined with Hassab operation was safe and efficacious to treat primary liver cancer associated with portal hypertension.

Objective:The aims of this study were to compare the efficacy between salvage liver transplantation (sLT) and rehepatectomy (RR) basing on the propensity score matching (PSM), and to explore the prognositc factors of patients with recurrent hepatocellular carcinoma (HCC).Methods:124 patients with intrahepatic recurrence after hepatectomy in our center from January 2012 to August 2018 were divided into sLT group( n=46) and RR group( n=78). 34 patients were selected for data analysis base on 1∶1 propensity score matching (PSM). The advantages and disadvantages of the two surgical methods and the prognostic factors of the patients were discussed by comparing the basic clinical data, OS and DFS of the two groups before and after matching. Results:Before matching, the pre-operative serum total bilirubin, the occurrence of multiple tumors, the proportion of preoperative TACE and the proportion of patients within Milan criteria of the sLT group were higher than those of the RR group, and the maximum tumor diameter of the sLT group was shorter than that of the RR group ( P<0.05); the time of operation, the amount of intra-operative blood loss, the positive of MVI and the proportion of postoperative Clavien grade Ⅲ and above of RR group were higher than those of RR group ( P<0.05). After matching, the operation time, intra-operative blood loss and the proportion of postoperative complications of sLT group were higher than those of RR group; there was nosignificant difference between 1-, 3- and 5- years OS of sLT group and RR group( P>0.05), the 1-, 3- and 5-years DFS of sLT group were better than those of RR group( P<0.05); AFP≥100 μg/L was the independent risk factor of OS, and the type of operation and AFP≥100 μg/L were independent risk factors of DFS. Conclusions:The pre-operative condition of sLT group was more severe, and the operation time, intra-operative blood loss and post-operative severe complication rate of sLT group were higher than those of RR group, and the DFS time of sLT group was longer than that of RR group, but there was no significant difference in OS between the two groups.

Objective To systematically evaluate the effect of routine insertion of double-J stents to prevent major urological complications(MUCs)in kidney transplant recipients.Methods Medline,Embase,Cochrane Library,and Chinese Biomedicine database were searched to locate relevant randomized controlled trials(RCT).Data extraction and assessment of methodologic quality were performed independently by two reviewers.Meta-analysis was performed by Revman 5.0 software.Results Ten RCT(including 1616 patients)were identified.By comparing the routine stent group with the no stent group,the meta-analysis showed:(1)incidence of urine leak,urinary obstruction and UTI was 4 times lower,6 times lower,increased by 52 % respectively(P<0.0001);(2)Patient and graft survival,rate of acute rejection,delayed graft function and hematuria were of no significant difference.In subgroup analysis,it was found:(1)Compared with the no stent group,the group in which stent duration was≤ 4 weeks had a lower incidence of MUCs and a higher incidence of UTI;meanwhile,the group in which stent duration was > 4 weeks had a much lower incidence of MUCs and the rate of UTI was increased without significant difference;(2)In the RCT of which urethral catheter duration was < 5 days,there were no significant differences between the two groups in MUCs and UTI.In the RCT of which urethral catheter duration was ≥5 days,the stent group had a lower incidence of MUCs and a higher incidence of UTI.Conclusion Routine stenting reduces the incidence of MUCs.Although the double-J stent increases the risk of UTI,it seems that UTI doesn't affect the outcome of transplantation.The stent duration should be within 4 weeks.For the stent recipients,the longer duration of urethral catheter,the lower incidence of MUCs,the higher incidence of UTI;thus,it is up to clinicians to decide the optimal duration of urethral catheter.Long term prescription of 480 mg cotrimoxazole once daily,from the operation day till after stent removal,effectively reduces the risk of UTI associated with stent placement.

Objective:To synthesize the mental resilience of Chinese children tested with the Resilience Scale for Chinese Adolescents (RSCA)to evaluate its status as well as the research status. Methods:Four Chinese elec-tronic databases including China Biology Medicine disc (CBM),VIP Database,China National Knowledge Infra-structure (CNKI)and WangFang Database were searched from database established to December 2014. Literatures that reported the mental resilience status of Chinese children tested with RSCA were included. A statistical formula was used to synthesize means and standard deviations to get a total score;the standard mean difference (SMD)and 95% confidence interval (95%CI)of scores measured with RSCA scale were used to conduct meta-analyses usingthe software of Review Manager 5. 2 for comparison between different subgroups. Results:Thirty-nine studies with 16 493 children were included for the final analysis. Quantitative synthesis results showed that the average total score of Chinese children was (3. 3 0. 6 ). The status of psychological resilience was at a good level. The average psychological resilience scores of girls,not left-behind children,urban children,Han children and not-only-child were higher than those of boys [SMD (95%CI):-0. 09 (-0. 14--0. 05 )],left-behind children [SMD (95%CI):-0. 37(-0. 56--0. 19)],rural children [SMD (95%CI):0. 26(0. 13 -0. 38)],minority children [SMD (95%CI):0. 12(0. 04-0. 21)]and only-children [SMD (95%CI):0. 30(0. 16-0. 44)]respectively. Conclusion:The mental resilience of Chinese children is modest with internal diversity.

Objective To determine the effect of COMMD7 inhibition on invasion and migration in liver cancer stem cells (LCSCs),and investigate the possible mechanism.Methods After LCSCs were infected by shRNA lentiviral vectors of COMMD7,adhesion assay and Transwell assay were used to detect the invasion and migration,and phalloidin staining was employed to observe the morphological changes.Western blotting was adopted to measure the expression of E-cadherin,N-cadherin and Vimentin.Results COMMD7 knockdown significantly inhibited the invasion and migration of LCSCs.The relative cell quantity of adhesion was 1.00 ± 0.12 and 2.35 ± 0.20 respectively in control cells and infected cells,suggesting there were significantly more adhesive cells in the infected group (P < 0.05).The relative cell quantity per visual field of migration was 1.00 ±0.04 and 0.24±0.03,and that of invasion was 1.00 ±0.05 and 0.24 ±0.04 respectively in the control cells and infected cells,and there were significantly less invasive and migrated cells in the infected group (P <0.05).What's more,COMMD7 knockdown also induced some morphological changes of cells corresponding to the weakened abilities of migration and invasion.All the changes above were associated with up-regulation of E-cadherin (P < 0.05) and down-regulation of N-cadherin and Vimentin (P <0.05),the molecules related to mesenchymal-epithelial transition (MET).Conclusion COMMD7 knockdown inhibits the invasion and migration in LCSCs,which may be through its regulation on the MET course.
