Objective:To evaluate the possible roles of IL-18 in HBV infection, and to clarify the immune state during IFN? therapy. Methods:Peripheral blood lymphocytes from 2 groups of HBV infectors(including 15 asymptomatic carriers,26 patients with chronic hepatitis B) and 10 healthy individuals (as normal controls) were analyzed by flow cytometry. The levels of IL-18 were also detected before, during, and at the end of IFNa therapy,Results: (1)The level of IL-18 was the lowest in asymptomatic carrier group. However there was no significant difference between chronic hepatitis and normal control. (2)The patients with chronic hepatitis were further divided into 4 subgroups according to the inflammation degree of liver. Results showed that the severity degree of liver inflammation was accompanied with the elevation of IL-18 production. (3)IL-18 in chronic hepatitis B correlated with serum ALT positively ( r = 0.61,P

0.05). Conclusion To adept the combined test of CEA CYFRA21-1 and NSE in lung flushing fluid is more sensitivity and more valuable application in clinic.

Objective: To study the influence of high cell incubating temperature on AMP-activated protein kinase(AMPK) activity and lipid metabolites of piglets hepatocytes in vitro.Method: Primary hepatocytes of piglets about age 55d were separated and cultured under 37 ℃(control) or 42 ℃(heat stress).The anabolic and catabolic products of [14C]-oleic acid were detected for hepatocytes and culture media at 60min,120min and 180min.There were 9 replicates per time point.Result: Heat stress activated AMPK activity and enhanced fatty acid oxidation.The production of [14C]-CO2 and [14C]-acid soluble metabolites(ASM) was higher in heat stress group than in the control.At the same time,heat stress depressed the incorporation of [14C]-oleate into phospholipids,monoglycerides,triglycerides,cholesterol and cholesteryl ester.Conclusion: Heat stress activated AMPK activity and enhanced the formation of anabolic products and depressed catabolic products in piglets hepatocytes in vitro.

The volatile oils of endophyte isolates R1 (Acremonium sp.) and R2 (Acremonium sp.) from Aqui-laria sinensis were extracted by solvent method. Twenty and sixteen ingredients were identified from the volatile oils of R1 and R2 by GC-MS, respectively. Fatty acids, such as oleic acid, linoleic acid, hexa-decanoic acid etc., were the main components, whereas terpenoids like 1,8-cineole, zingiberene, ar-curcumene were also found in both oils. It’s the first report about the volatile oil constituents of endophyte isolates from A. sinensis.

Background and purpose:Esophageal cancer is one of the common malignant tumors in our country. Anastomotic stenosis is a common complication after resection of esophageal cancer, seriously affecting the quality of life of patients after operation. By changing anastomosis, this study explored the methods for prevention of anastomotic stenosis after esophageal cancer surgery.Methods:Patients were randomly divided into groups. Patients admitted on odd dates were placed in the control group whereas patients admitted on even dates were placed in the experimental group. Patients in the control group were treated with gastroesophageal anastomosis using anastomat for gastroesophageal anastomosis. Anastomotic stomach was contracted by purse string suture at first, and then treated with stapler gastroesophageal anastomosis, before the gastroesophageal anastomosis was carried out on patients in the experimental group. After 6 months’ follow-up, the incidences of anastomotic stenosis between the two groups were compared.Results:The postoperative anastomotic stenosis rate in the control group was 19.2%, while that in the exper-imental group was 0%. There were statistically signiifcant differences between them (χ2=22.8,P<0.005). The incidence of anastomotic stenosis in the control group was signiifcantly higher than that in the experimental group.Conclusion:Anastomotic stomach contracted by purse string suture before stapler gastroesophageal anastomosis can effectively reduce the occurrence of anastomotic stenosis after esophageal cancer surgery.

Grass carp reovirus (GCRV), a disaster agent to aquatic animals, belongs to Genus Aquareovirus of family Reoviridea. Sequence analysis revealed GCRV genome segment 8 (s8) was 1296 bp nucleotides in length encoding an inner capsid protein VP6 of about 43kDa. To obtain in vitro non-fusion expression of a GCRV VP6 protein containing a molecular of fluorescence reporter, the recombinant baculovirus, which contained the GCRVs8 and eGFP (enhanced green fluorescence protein)genes, was constructed by using the Bac-to-Bac insect expression system. In this study, the whole GCRVs8 and eGFP genes, amplified by PCR, were constructed into a pFastBacDual vector under polyhedron (PH) and p10 promoters, respectively. The constructed dual recombinant plasmid (pFbDGCRVs8/eGFP) was transformed into DH10Bac cells to obtain recombinant Bacmid (AcGCRVs8/eGFP) by transposition. Finally, the recombinant bacluovirus (vAcGCRVs8/eGFP) was obtained from transfected Sf9 insect cells. The green fluorescence that was expressed by transfected Sf9 cells was initially observed 3 days post transfection, and gradually enhanced and extended around 5days culture in P1(Passage1) stock. The stable high level expression of recombinant protein was observed in P2 and subsequent passage budding virus (BV) stock. Additionally, PCR amplification from P1 and amplified P2 BV stock further confirmed the validity of the dual-recombinant baculovirus. Our results provide a foundation for expression and assembly of the GCRV structural protein in vitro.

Objective To investigate the correlated pathogenetic factors and vaginal local immunity in vulvovaginal candidiasis (VVC). Methods A case control study was conducted to compare VVC group (60 cases) with normal group (60 cases). All of the women filled up the specific questionnaires. Routine examination, pH test and bacterial culture were done on the vaginal discharge. Cytokines of the vaginal lavage were measured by enzyme linked immanosorbent assay. Results (1) Outcomes of the questionnaires: there was no significant difference between the two groups in educational background,knowledge of gynecologic infection, history of gynecologic infection, hygienic habit, sex life, or use of medicine (P >0. 05). The incidence of chronic cervicitis in normal group (43%, 26/60) was higher than in VVC group (22%, 13/60; P <0.05). (2) There was no difference in vaginal pH between the two groups ( P > 0. 05 ). (3) Detection rate of candida albicans by vaginal discharge routine examination was 72% (43/60). (4) The concentrations of interleukin (IL) 2, and IL-4 in vaginal lavage did not show significant difference between the two groups ( P > 0. 05 ), but the concentrations of human defensin 5,human beta-defensin (HBD) 1, and HBD2 in WC group [(0.94±0.44) mg/L, (3.1±0.4) μg/L,(10±6) μg/L] were higher than normal group (P < 0.05). Conclusions VVC is a common vulvovaginitis. There is no significant correlation between the incidence of VVC and educational background,knowledge of gynecologic infection, history of gynecologic infection, hygienic habit, sex life, or use of medicine in the child-bearing period. Human defensin may be closely correlated with the pathogenesis of VVC.

The aimed of this study was to prepare stabilized thiomers to overcome the poor stability character of traditional thiomers. Poly(acrylic acid)-cysteine (PAA-Cys) was synthesized by conjugating cysteine with poly(acrylic acid) and poly(acrylic acid)-cysteine-6-mercaptonicotinic acid (PAA-Cys-6MNA, stabilized thiomers) was synthesized by grafting a protecting group 6-mercaptonicotinic acid (6MNA) with PAA-Cys. The free thiol of PAA-Cys was determined by Ellmann's reagent method and the ratio of 6MNA coupled was determined by glutathione reduction method. The study of permeation enhancement and stabilized function was conducted by using Franz diffusion cell method, with fluorescein isothiocyanate dextran (FD4) used as model drug. The influence of polymers on tight junctions of Caco-2 cell monolayer was detected with laser scanning confocal fluorescence microscope. The results indicated that both PAA-Cys and PAA-Cys-6MNA could promote the permeation of FD4 across excised rat intestine, and the permeation function of PAA-Cys-6MNA was not influence by the pH of the storage environment and the oxidation of air after the protecting group 6MNA was grafted. The distribution of tight junction protein of Caco-2 cell monolayer F-actin was influenced after incubation with PAA-Cys and PAA-Cys-6MNA. In conclusion, stabilized thiomers (PAA-Cys-6MNA) maintained the permeation function compared with the traditional thiomers (PAA-Cys) and its stability was improved. The mechanism of the permeation enhancement function of the polymers might be related to their influence on tight junction relating proteins of cells.

Objective: To compare the efifcacy and safety of sirolimus-eluting stent (SES) and everolimus-eluting stent (EES) for treating the patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS). Methods: A total of 400 NSTE-ACS patients treated in Jining Medical College Hospital from 2013-09 to 2014-09 were studied. According to different stents, the patients were divided into 2 groups: SES group,n=220 and EES group,n=180. A prospective follow-up study was conducted for 1.5 years to compare the incidence rate of major adverse cardiovascular events (MACE). The patients were further stratiifed by GRACE scores as Low risk group (score<109), Medium risk group (score 109-140) and High risk group (score>140). MACE free survival was studied by Kaplan-Meier curve and analyzed by Long-rank test, predictive value of GRACE for 1.5 year MACE incidence rate was examined. Results: There were 355/400 (89%) patients completed (16.7 ± 5.7) months of follow-up study including 205 in SES group and 150 in EES group. MACE occurrence rates were similar between SES group and EES group (16.10% vs 18.0%), P>0.05. By GRACE score stratiifcation, MACE rates in High risk SES group were higher than High risk EES group (48.00%vs 16.00%),P<0.05; while they were similar between Medium risk groups (14.49% vs 28.00%) and Low risk groups (9.11% vs 12.86%), allP>0.05. ROC curve indicated that the predictive value of GRACE score for 1.5 year MACE incidence was for AUC=0.762, 95% CI (1.026-1.050),P<0.001. Conclusion: Implanting of EES would be more beneifcial for NSTE-ACS patients with high GRACE risk; GRACE score has the better predictive value for their long-term prognosis.
