Objective To explore the short-term and long-term efficacy of partial splenic artery embolization(PSE)in the treat-ment of cirrhosis with hypersplenism.Methods A retrospective analysis was conducted on 35 patients with cirrhosis and hyper-splenism who underwent PSE treatment.Data on white blood cell(WBC),red blood cell(RBC),platelet count(PLT),hemoglobin(HGB),total bilirubin(TBiL),albumin(ALB),prothrombin time(PT),and D-dimer were collected at the three time points:before surgery,1 week after surgery,and 1 year after surgery.The changes in these parameters across the three time points were observed and compared.One-way ANOVA was used for repeated measurements,and time pairwise comparisons were made between the three time points.According to the formation of portal thrombosis,patients were divided into thrombus group and no-thrombus group.The D-dimer values were compared before surgery and 1 week after surgery.Results WBC and PLT were significantly higher 1 week and 1 year after surgery than those before surgery,with the most significant increase 1 week after surgery,and there was also statistically sig-nificant difference between 1 week after surgery and 1 year after surgery(P1,P2,P3<0.05).There were no significant differences in RBC and HGB between 1 week after surgery and before surgery(RBC P1=0.835,HGB P1=0.446).However,RBC and HGB 1 year after surgery were significantly higher than those before surgery and 1 week after surgery(RBC P2=0.039,P3=0.015;HGB P2=0.001,P3=0.010).There were significant differences in TBiL,ALB,PT,and D-dimer 1 week after surgery compared with those before surgery(TBiL P1=0.006,ALB P1<0.001,PT P1=0.001,D-dimer P1<0.001),but there was no significant differ-ence between 1 year after surgery and before surgery(all P2>0.05).The D-dimer of the thrombus group was significantly higher than that of the no-thrombus group 1 week after surgery,with a statistical significance(P=0.024),however,there was no signifi-cant difference in D-dimer between the two groups before surgery.Conclusion PSE in the treatment of cirrhosis with hypersplenism shows positive short-term and long-term efficacy for WBC and PLT.The short-term increase of RBC and HGB is not obvious,however the long-term efficacy is significant.In the short-term after surgery,TBiL increase,ALB decrease,PT prolonge,and liver reserve function decrease,but there was no long-term effect.The increase of D-dimer after surgery can easily induce portal thrombosis,and anticoagulation therapy can be given in the short-term after surgery.

Objective To investigate the risk factors of overt hepatic encephalopathy(OHE)and death in cirrhotic portal hyperten-sion patients after transjugular intrahepatic portosystemic shunt(TIPS).Methods A retrospective selection was conducted on 40 patients with cirrhotic portal hypertension who underwent TIPS.The follow-up time was 3-41 months,median follow-up time was 20.36 months.The postoperative hepatic encephalopathy(HE)were divided into OHE group(20 cases)and non-OHE group(20 cases)and were further divided into death group(11 cases)and survival group(29 cases)according to their postoperative survival status.Gender,age,preoperative height,weight,total bilirubin,albumin,alanine aminotransferase,aspartate aminotransferase,creatinine,international normalized ratio(INR),prothrombin time,blood glucose,white blood cells,hemoglobin and platelet of all patients were recorded in detail,as well as whether they had diabetes and portal thrombosis before surgery.Child score and model for end-stage liver disease(MELD)score were also performed.The related risk factors of HE and death were obtained by statistical analysis of the two groups.Results The incidence rate of OHE after TIPS was 50%.The analysis revealed that age[hazard ratio(HR)1.115,95%confidence interval(CI)1.007-1.234,P=0.036]and albumin(HR 0.776,95%CI 0.627-0.960,P=0.020)were independent risk factors for OHE after TIPS.The receiver operating characteristic(ROC)curves were drawn with area under the curve(AUC)of 0.733 for age and AUC of 0.784 for albumin.The mortality rate after TIPS was 27.5%,and the analysis indicated that albumin(HR 0.660,95%CI 0.453-0.961,P=0.030),creatinine(HR 1.031,95%CI 1.001-1.062,P=0.044),and aspartate aminotransferase(HR 1.074,95%CI 1.013-1.139,P=0.018)were independent risk factors for death after TIPS.The ROC curves were drawn with AUC of 0.716 for albumin,AUC of 0.762 for creatinine,and AUC of 0.710 for aspartate aminotransferase.Conclusion Postoperative OHE is posi-tively correlated with age and negatively correlated with albumin.Furthermore,the risk of postoperative death is positively correlated with creatinine and aspartate aminotransferase and negatively correlated with albumin.

Objective To evaluate the accuracy and feasibility of time-resolved immunofluorometric assay (TRI FA) for detection of HBsAg based on Abbott automated chemiluminescence immunoassay(CMIA),so as to carry out this project in primary hospitals,and provide reference for individual antiviral strategy and prediction of therapeutic effect.Methods Serum of 157 patients infected with hepatitis B virus were detected with CMIA and TRIFA,specimens with HBsAg titers exceeding the detection limit were firstly diluted,then performed quantitative analysis.HBsAg levels were divided into 4 groups:≤100 IU/mL,101-1 000 IU/mL,1 001-20 000 IU/mL,and ＞ 20 000 IU/mL,quantitative correlation between two methods was analyzed.Results The linear regression equation of two methods was Y=2.323X-896.3,correlation coefficent r=0.943,P＜0.001.CMIA was as a reference,4 groups were divided for analysis,results showed that when detected specimens was at low concentration of HBsAg,TRIFA value was low compared with CMIA method,while detected specimens was at high concentration of HB sAg,CMIA value was high,two reagents had good consistency in the detection of different concentrations of HBsAg(both P＜0.05),when concentration was at 1 001-20 000 IU/mL,consistency was the best.Conclusion The accuracy of two reagents in the quantitative detection of HBsAg is similar,and the best correlation of detection value is 1 000-20 000 IU/mL.TRIFA assay has wide application for its low-cost and easy to be operated,which is especially suitable for primary hospitals.

OBJECTIVE: To determine whether time-resolved immunofluorescence assay (TRIFA) shares the similar accuracy and specificity with automatic chemiluminescence immunoassay (CMIA) in analyzing HBeAg levels in hepatitis B.
 METHODS: A total of 157 serum samples were collected from outpatients with infection of HBV in Xiangya Hospital, Central South University. CMIA and TRIFA were used to analyze HBeAg quantitation and HBeAg/HBeAb qualitative detection, respectively.
 RESULTS: The linear regression equation for the two methods was Y=0.72779X-4.0551 (r=0.712, P<0.001). Compared with the CMIA, the sensitivity and specificity in detection of HBeAg by TRIFA were 89.89% and 100%, respectively, and the coincidence rate of HBeAg was 94.27% by two assays. Similarly, the sensitivity and specificity in detection of HBeAb by TRIFA were 100% and 95.45%, respectively. The coincidence rate was 97.45% by two assays.
 CONCLUSION TRIFA has similar accuracy, sensitivity, and specificity with CMIA in quantitative detection of HBeAg, and their coincidence rate in detection of HBeAg/HBeAb is high.

Mesenchymal stem cells (MSCs) are multipotent stem cells that differentiate into a variety of cell types. Low frequency pulsed electromagnetic fields (LFPEMFs) therapy can causes biochemical changes at the cellular level to accelerate tissue repair in mammals. So, we tested the hypothesis that LFPEMFs can promote chondrogenic differentiation of rat bone marrow-derived mesenchymal stem cells (rBMSCs) in vitro. The rBMSCs were isolated by adherence method and the third-generation of the rBMSCs were randomly divided into LFPEMFs groups, chondrocyte-induced group and control group. LFPEMFs groups with complete medium were exposed to 50Hz, 1mT PEMFs for 30 min every day, lasting for 10, 15 and 20 d, respectively. Chondrocyte-induced group were treated with chondrogenic media, while control groups were only cultured with complete medium. The mRNA expressions of type II-collagen (Col II) and aggrecan were determined by Real-time fluorescent quantitation PCR. The protein expression of Col II and aggrecan were detected with toluidine blue stain or immunocytochemical stain, respectively. The result showed that the mRNA and protein expression level of Col-II and aggrecan were significantly higher in the LFPEMFs group or chondrocyte-induced group, compared to the control group. It suggest that LFPEMFs could contribute to rBMSCs to differentiate into chondrogenic differentiation in vitro.
