Ductular reaction (DR) is a phenomenon that refers to impaired hepatocellular proliferation and activated hepatic stem cells at times of demand such as hepatic regeneration.The components of ductular reactions are thought to be derived from activated hepatic progenitor cells,intermediate hepatobiliary cells,and reactive ductular cells.DRs are thought to play two roles in hepatocarcinogenesis:their hepatic progenitor cells may undergo malignant transformation and migration,and they may contribute to the development of the tumor's microenvironment.Exploring DR phenotype,cellular diversity,and relationship to hepatocarcinogenesis will further enhance our understanding of the pathogenesis of human hepatocellular carcinoma with an ultimate goal of developing new therapies.

Objective To explore the effects of human menopausal gonadotropopin(HMG) supplementation on the outcome of women underwent in vitro fertilization-embryo transfer(IVF-ET) .Methods The data of 406 IVF-ET cycles in Reproductive Medi-cine Center of the 105th Hospital of PLA were analyzed retrospectively .All cases underwent long down regulation protocol with gonadotropin releasing hormone agonist(GnRH-a) in the mid-luteal phase and controlled ovarian stimulation(COS) was carried out with follicle stimulation hormone(r-FSH) on the days 3 -5 of the menstrual cycle .Then 75 -150 U HMG was administrated in group A(257 cycles) when a dominant follicle reached a diameter of 14 mm ,while the remaining cases(149 cycles) underwent HCG still with r-FSH were served as group B .Based on the LH levels on the day of HMG administration ,the cases in group A were sub-divided into :group A1(99 cycles) ,LH<1 U/L ;group A2(96 cycles) ,1 U/L≤LH≤2 U/L ,and group A3(62 cycles) ,LH>2 U/L .Clinical outcomes of all groups were analyzed and compared .Results The durations and doses of gonadotropin(Gn) ,the rates of fertilization and pregnancy were higher and the abortion rate was lower in group A than that in group B (P<0 .05) .There were no significant difference in serum LH concentrations on the days of HMG and HCG administration ,oocytes retrieved ,the rates of cleavage and embryo implantation between group A and group B(P>0 .05) .There was significant difference in serum LH levels on the day of HMG supplementation among group A1 ,A2 and A3(P<0 .05) and the doses of HMG supplemented reduced gradually from group A1 to group A3(P<0 .05) .The duration of Gn was significantly lower and the fertilization rate was significantly higher in group A3 compared with group A1 and A2(P<0 .05) .The pregnancy rate in group A2 and A3 was higher than that in group A1 ,which showed significant difference between group A2 and A1(P<0 .05) .Meanwhile ,there were no significant difference in doses of r-FSH ,serum LH concentrations on the day of HCG administration ,oocytes retrieved ,the rates of cleavage ,implantation and abortion among the three groups(P>0 .05) .Conclusion HMG supplementation in the middle and late follicle phases in stand-ard long down-regulation protocol during IVF could obtain higher pregnancy rate and lower abortion rate ,especially when their ser-um LH level was between 1 U/L and 2 U/L without obvious increase of LH .

Objective To investigate the effect and possible mechanism of erlotinib,an epidermal growth factor recceptor inhibitor,on human pancreatic cancer cell lines BxPC3 in vitro.Methods Methyhhiazolyhetrazolium(MTT)assay was used to detected the proliferation of BxPC3 after exposure to erlotinib,apoptosis and cell cycle changes were studied by flow eytometry and terminal deoxynucleotidyl transferase-mediated nick end labeling assay(TUNEL).The expressions of bcl-2 mRNA,bax mRNA,bcl-xL mRNA and bak mRNA were determined by reverse transcriptase polymerase chain reaction(RT-PCR). Results Edotinib inhibited BxPC3 cells growth in a dose and time dependent manner in vitro.The cell viabilities in erlotinib 1 μmol/L and 100 μmol/L groups 72 h later were(90.25 ±2.62)%and(40.75 ±2.98)%,and the difference was statistically significant(P<0.01).The cell viability in edotinib 50 μmol/L groups 24 h and 96 h after BxPC3 exposure were(74.0±4.08)%and(49.50 ±1.29)%,and the difference was statistically significant(P<0.01).Cell apoptosis rate in erlotinib 50 μmol/L group was(11.0 μ1.1)%,which was significantly higher than(6.2 ±1.1)%in control group(P<0.01).G_0/G_1 cell accounted for (73.4±1.3)%of all the cells,which was significantly higher than(63.3 ±1.O)%in control group.With transmission electron microscope,the morphology of BxPC3 ceils showed typical apoptosis and apoptotic body. The expressions of bcl-2 mRNA,bel-xl mRNA were down-regulated,while the expression of bax mRNA was slightly up-regulated,and the expression of bak mRNA was not affected.Conclusions The growth of BxPC3 cells could be suppressed by erlotinib and possible mechanisms involved blocking cell cycle,up-regulating apoptosis proteins and down-regulating apoptosis inhibitor proteins.

Objective To study CT value of diagnosis and identified diagnosis in osteolytic metastases of the vertebral column through describing their CT manifestation.Methods In 46 patients, 72 vertebrae osteolytic metastases were analyzed and compared with X-ray findings of 28 cases.Results In 72 vertebrae osteolytic metastases, there were destruction of 74 corpus vertebrae in 45 patients, of pediculus arcus vertebraes in 22 cases, of processus transverses in 15 cases, of processus spinosus in 11 cases and lamina vertebrae in 11 cases. Micrometastases were concentrated in corpus vertebrae(45/49). CT found the rate of bone-destruction, affection of vertebrae canal and soft tissue around vertebrae were 100%, 67.8% and 71.4%, but the corresponding rates were only 53.6%, 14.3% and 32.1% by X-ray. Conclusion Vertebral column metastases destructed corpus vertebrae at first, vertebral metastases are the origin or base of destruction of the pediculus arcus vertebrae, lamina vertebrae, processus transverses and processus spinous. CT scanning is more sensitive in finding and evaluating the lesions than X-ray plain film.

Purpose To investigate the effect of subcellular location of tumor BRCA1 on the sensitivity to ionizing radiation (IR) and PARP inhibitor.Methods siRNA of BRCA1 were first used to inhibit endougenous BRCA1 expression in MCF7 cells.Then,plasmids of pCMV-3xFlag-WT-BRCA1,pCMV-3xFlag-NES-BRCA1 and pCMV-3xFlag-NLS-BRCA1 were transfected in MCF7 cells.Immunofluorescence staining was used to detect BRCA1 subcellular location as well as the formation of Rad51 and γ-H2AX foci.Apoptotic cells were analyzed by flow cytometry,and colony formation assay was performed to evaluate the survival of cells.Results There were 47％ cells with nuclear BRCA1,23％ cells with cytoplasmic BRCA1 and 30％ cell with mixed nuclear and cytoplasmic BRCA1 expression in WT-BRCA1 transfected cell.There were 87％ cells with nuclear BRCA1 in NES-BRCA1 transfected cell,and 82％ cells with cytoplasmic BRCA1 in NLS-BRCA1 transfected cell.There were 87％,84％ and 13％ Rad51 foci positive cells at 2 hours after 4 Gy radiation treatment and 22％,25％ and 59％ γ-H2AX foci positive cells at 24 hours after 4Gy radiation treatment in WT-BRCA1,NES-BRCA1 mutant and NLS-BRCA1 mutant transfected cell respectively.ABT-888 and radiation treatment induced more apoptosis and fewer colonies in NLS-BRCA1 transfected cell than WT-BRCA1,NES-BRCA1 mutant transfected cell.Conclusion Subcellular location of BRCA1 might affect homologous recombination repair of DNA double strand breaks and can be used to predict sensitivity to IR and PARP inhibitor.

Objective To investigate the relationship between Epstein-Barr virus (EBV) DNA and EBV serology markers and evaluate the clinical application values in different diseases.Methods Plasma samples from 397 diagnosed EBV infection-associated patients and 120 health donors from May 2014 to November 2015 in Wuhan Tongji Hospital were collected.Real-time fluorescent quantitative PCR was performed to detect the levels of EBV-DNA in peripheral blood mononuclear cell and plasma.ELISA was used to detect VCA IgA,VCA IgM,VCA IgG,EA(D) IgG and EBNA IgG antibodies in plasma.The positive rate of EBV-DNA and EBV antibodies were counted in each group according to the detection threshold.Kappa statistic and Spearman sank correlation test were used to analysis the correlation and uniformity between EBV-DNA and EBV serology indicators.Results The positive rate of VCA IgG in patient and health control was 94.2% (374/397) and 93.3% (112/120) respectively (χ2=0.125,P=0.67);The positive rate of EBNA IgG in patient and health control was 95.4% (379/397) and 95.0% (114/120) respectively (χ2=0.045,P=0.807);but the positive rate of VCA IgM was 5.5% (22/397) and 0% (0/120) respectively (χ2=6.9,P<0.01);The positive rate of VCA IgA was 43.3% (172/397) and 9.2% (10/120) respectively (χ2=49.5,P<0.01);The positive rate of EA(D) IgG was 42.0% (167/397) and 7.5% (9/120) respectively (χ2=49,P<0.01).The positive rate of EBV-DNA was 65.5% (260/397) and 16.7% (20/120) respectively (χ2=88.5,P<0.01);The positive rate of EBV-DNA in plasma was 45.8% (182/397) and 5.0% (6/120) respectively (χ2=66.4,P<0.01).Furthermore,the uniformity and Spearman correlation analysis showed that there was no significant correlation between EBV-DNA and EBV serology indicators.The correlation analysis between PBMC EBV-DNA and VCA IgM,VCA IgA,EA(D) IgG showed the Kappa was 0.073,0.147,0.073,respectively;the correlation analysis between plasma EBV-DNA and VCA IgM,VCA IgA,EA(D) IgG showed the Kappa was 0.144,0.369,0.288,respectively.Thus,the patients were divided into different groups according to the discharge diagnosis,it was observed that the positive rates of EBV-DNA is more than 90% in extra-nodal NK/T cells lymphoma,EBV-associated hemophagocytic lymphoid tissue hyperplasia,chronic active EBV infection and infectious mononucleosis.In nasopharyngeal carcinoma patients,the positive rate of EBV antibodies (VCA IgA and EA(D) IgG) were higher than the detection of EBV-DNA.Conclusions There was no significant correlation between EBV-DNA and EBV serology markers for the same sample.The clinical application values of EBV DNA and EBV serology markers were not identical in nasopharyngeal carcinoma,extra-nodal NK/T cells lymphoma,infectious mononucleosis and EBV-associated hemophagocytic lymphoid tissue hyperplasia.

BACKGROUND:Systemic lupus erythematosus (SLE) is classified into four types, and the major treatment is to tonify kidney and nourishyin, clear blood stasis and toxin by the traditional Chinese medicine (TCM). Even though, there are stil many patients with poor efficacy. Mesenchymal stem cels have the capacity of multiple differentiation, hematopoietic support and immune regulation, thus having been used for the treatment of refractory, recurrent SLE and achieving good effects. OBJECTIVE:To investigate the therapeutic effect of umbilical cord-derived mesenchymal stem cel transplantation on SLE patients with different patterns of syndromes. METHODS: Twenty-one SLE patients were clustered to four syndrome types of TCM, including heat-toxin,yin deficiency of liver and kidney,yang deficiency of spleen and kidney, andqi stagnation and blood stasis. The changes in clinical and laboratory indicators were analyzed statisticaly before and after cel transplantation. RESULTS AND CONCLUSION:The level of 24-hour proteinuria and SLE disease activity index scores in SLE patients were significantly decreased at 1, 3, 6 months after cel transplantation (P < 0.01). Umbilical cord-derived mesenchymal stem cel transplantation could significantly reduce the 24-hour proteinuria in SLE patients withyin deficiency of liver and kidney at 1, 3 and 6 months (P < 0.01), while slightly reduce the 24-hour proteinuria in SLE patients with heat-toxin andqi stagnation and blood stasis at 1, 3 months (P < 0.05) as wel as in SLE patients withyang deficiency of spleen and kidney at 1 month (P < 0.05). Additionaly, umbilical cord-derived mesenchymal stem cel transplantation could increase the serum albumin levels in al the SLE patients (P < 0.01), although the changes in patients with heat-toxin were moderate (P < 0.05). Al the SLE patients of four types had an increasing trend of their platelet counting after cel transplantation, but there was no statistical difference before and after cel transplantation. Taken together, umbilical cord-derived mesenchymal stem cel transplantation is effective for treatment of SLE, but has different therapeutic efficacy on SLE patients with different syndrome types of TCM.
