Objective To explore the clinical value of serum interleukin(IL)-33 and its soluble receptor ST2(sST2) level in patients with chronic hepatitis B.Methods A total of 65 cases with chronic hepatitis B were recruited into study group,meanwhile 60 healthy persons were enrolled in the control group from January 2014 to October 2016 in our hospital.IL-33,sST2 and alanine aminotransferase(ALT) were detected and compared in the two groups.Results The level of IL-33,sST2 and ALT were significant higher than those of the control group(t=6.542,7.218,6.324;P<0.05).IL-33 and sST2 levels in chronic hepatitis B patients with abnormal ALT level were significant higher than those with normal ALT(t=16.328,9.874,P<0.05).Conclusion The detection of IL-33 and sST2 in patients with chronic hepatitis B could help to understand the immune status of patients,and provide a theoretical basis for the treatment of chronic hepatitis B.

This study aimed at comparing the United States, Britain, Australia, the Netherlands and China’s national performance evaluation, and sum up the experience to provide a theoretical basis for the China’s development of hospital performance evaluation system. The study found that China needs to consider the patient's perspective, to establish a fixed third-party performance evaluation agencies, establish an effective incentive mechanism and feedback mechanism and combine a variety of assessment methods in the development of hospital performance evaluation index system.

0.05), the percentage of MDC and PDC and the ratio of MDC/PDC at the second (MDC, 0.11%?0.09%; PDC, 0.06%?0.05%; MDC/PDC, 0.76?0.80), third trimester (MDC, 0.12%?0.08%; PDC, 0.07%?0.06%; MDC/PDC, 0.78?0.82) were significantly lower (P

The paper described the development stages of a hospital performance evaluation scale based on patient experience.An empirical application on 7 856 patients of 26 hospitals in four provinces in the country identified the challenges encountered in the course of its application.These include limits of patients experience,variations on the experience reports incurred by different services experienced by patients,and setting of the patient-inpatient ratio among others.Solutions proposed based on these studies aim at creating a patient experience scale tailored to Chinese patients.

Objective To investigate the effect of MHC class Ⅱ transactivator( MHC Ⅱ TA ) on MHC Ⅱ expression of human and rat pancreatic cancer cell line CaPanC-2 and PanC-02. Methods The recombinant adenovirus (Ad-C Ⅱ TA) was transfected into the CaPanC-2 cell and the PanC-02 cell, then it was cultured for 24, 48, 72 h. The C Ⅱ TA mRNA expressions were assayed by Real Time PCR and CⅡ TA protein expressions were determined by Western blotting. The percentage of positive expression cells of MHC Ⅱ were measured by flow cytometry. Results The C Ⅱ TA mRNA expressions of CaPanC-2 cell at 24, 48, 72 h were 16769 ± 6455, 261568 ±348850 and 834816 ±97783 folds higher than that of control group (P <0.05). The CⅡTA mRNA expressions of PanC-02 was 548546 ± 87755, 1242684 ± 624888 and 1401647 ± 726145 folds higher than that of control group ( P <0.05). CⅡ TA protein was not expressed in CaPanC-2 cell and PanC-02 cell. After transfection for 48 h, the CⅡ TA protein expressions of CaPanC-2 and PanC-02 were 0.746 ± 0.499 and 0.631 ±0.244. The percentage of positive expression cells of MHC Ⅱ in CaPanC-2 cells after 24, 48, 72 h were (8.1±0.3)%, (18.9±0.3)%, (78.5±0.90%, which were significantly higher than that in control group [ ( 7.0 ± 0.1)% , P < 0.01 . The percentage of positive expression cells of MHC Ⅱ in PanC - 0 2 were (5.1 ±0.2)% , (37.3 ±2.0)% , (68.8 ±2.2)%, which were significantly higher than that in control group [ (2.2 ±0.2)% , P <0.01). Conclusions Transfection of Ad-C Ⅱ TA could increase the expression of CⅡTA and MHC Ⅱ molecules of pancreatic tumor cells in vitro.

AIM: To study the changes of mitochondrial membrane potential(△?m) and mitochondrial mass in apoptosis of Jurkat cells induced by camptothecin(CPT).METHODS: Jurkat cells were treated with CPT.Annexin V-FITC/propidium iodine(PI) double stainig was used to detected early stage of apoptosis and PI staining for analyzing the cell cycle.Jurkat cells were stained by annexin V-PE/DiOC_6(3) to detect changes of △?m.The mitochondrial mass was measured by cytometry with NAO staining.RESULTS: 6 h after treated with 10 ?mol/L CPT,the rate of early apoptotic cells(22.59?1.04)% had significantly difference compared with control group(3.93?0.73)%(P0.05).Apoptotic peak appeared obviously after treated with CPT,the percentage of late apoptotic cells(13.58?0.97)% had distinctly difference compared with control group(3.18?0.51)%(P

AIM: To investigate the effects of 17?-estradiol (E 2) on the maturation and immunologic function of dendritic cells from human peripheral blood. METHODS: Cultured DCs were treated with E 2 at doses of 10 -7 mol/L and 10 -6 mol/L. The morphologic changes were observed under the scanning electronic microscope. The immunophenotype of DCs in control and treated groups was analyzed by flowcytometry. IL-12 production in culture supernatant was examined by ELISA assay. The capability of the stimulatory activity of the DCs on allogeneic T cells in mixed reaction was tested by incorporation of 3H]-TdR. RESULTS: Compared with control group, DCs cultured in the presence of E 2 displayed less dendritic pseudopod, expressed low levels of MHC-II, CD40, CD80 and CD86, and exhibited weakly activity in stimulating the proliferation of allogeneic T cells and reduction of IL-12 production. CONCLUSION: E 2 exerts a negative effect on the maturation and immunologic function of dendritic cells from human peripheral blood.

AIM: To study the relation between prolon ge d survival of skin allograft by chuan-ke-zhi (CKZ, drug of Chinese herbal) and C D4+CD25+ regulatory T cells (CD4+CD25+ Tr) in mice. METHODS: Skin allograft and isograft model in mice were establi shed and CKZ was administered by intraperitoneal injection. To observe its influ ence on survival of the graft, three color fluorescent staining together with fl ow cytometry was used to analyze the change of CD4+CD25+ Tr. RESULTS: The survival of skin allograft in CKZ group was signifi cantly prolonged compared to control group, (19.5?2.3) days and (10.2?2.2) days, respectively, P0.05). CONCLUSION: CKZ has an effect of prolonging the survival of skin allograft. Enhancement of CD4+CD25+ Tr might be one of the mechanisms under lying its immunosuppressive effect.

Objective To compare the efficacy and safety of E1B gene-deleted adenovirus (H101)and ethanol in treating advanced pancreatic carcinomas by intratumoral injection combined with intravenous gemcitabine.Methods We constructed an orthotopic nude mouse model of pancreatic carcinoma through cancer cell injection into pancreas.A total of 54 nude mice were randomly allocated to 6 groups to accept H101,ethanol or saline (control) intratumoral injection,combined with or without intravenous gemcitabiein.The animals were sacrificed 4 weeks after the treatment and the pancreatic tumors were collected to determine the size,existence of metastasis,distribution of virus by indirect immunofluorescence and apoptosis in tumor by TUNEL and electron microscope.Results All mice completed the scheduled treatment,while 3 died in 48 hours after ethanol injection resulting in a mortality of 16.7％ (3/18).On the contrary,no mice died in the adenovirus injcction group.The average tumor size in group of H101 intratumoral injection combined with intravenous gemcitabie was significant smaller than that in group of saline injection with or without systemic gemcitabie (P =0.008,0.040,respectively).Similar differences were observed between ethanol intratumoral injection and control groups (P =0.012,0.041).Meanwhile,the H101 was absent in all the other organs except the pancreas,which meant that the selectivity of the H101 was tremcndous.The virus combine gemcitabie group had higher apoptosis rate in tumor (83.2 ± 35.7) ％,determined by TUNEL.Conclusion E1B gene-deleted adenovirus intratumral injection in combination with intravenous gemcitabine treating pancreatic carcinomas is efficient and safe,in spite of its lower effectiveness than ethanol.
