Objective To explore the pathogenicity of Campylobacter jejuni(CJ)O∶19 strain after deletion of neuB1.Methods The mutant of CJ O∶19 by deleting neuB1,which LPS is deficient in sialic acid,was compared with the homologous wild strain by assaying their sensitivity to bactericidal activity,motility and autoagglutination of 10% normal human serum(NHS).Results The sensitivity of the mutant strain to bactericidal activity of serum was superior to that of the wild strain.The survival rate of the mutant strain was(20.6?7.4)% and(9.6?3.6)% after incubation with 10% NHS for 15 min and 60 min,that of wild strain was(36.9?5.9)% and(15.5?4.3)% respectively.The wild and mutant strains showed no significant difference in sensitivity to motility and autoagglutination of NHS.Conclusion The mutant strain possesses remarkable pathogenicity so that an inactivated vaccine from the mutant strain should be first considered.

Aim To explore the differences of pathogenesis for the hepatotoxicity induced by chronic treatment of valproic acid(VPA) in different ages,and in combination administration with inducers of liver enzyme.Methods Animal models were established by oral administration chronically with VPA at doses of 200 or 500 mg?kg~(-1) per day in 30 days for 50 Wistar rats(infant and adult rats) with inducers of liver enzyme Phenobarbital(PB) or not.Mitochondria were obtained by differential centrifugation.Levels of liver enzymes,coagulation factors,plasma ammonia,VPA and PB serum levels,and L-carnitine in sera,as well as the changes of respiratory enzymes and lipid peroxidation in hepatic mitochondria were measured.Mitochondrial membrane potential(MMP) and mRNA expression of CYP450 reductase in liver were determined by flow cytometer and in situ hybridization,and morphological changes of hepatocytes were observed under microscope with Oil-Red-O staining.Results ① In all rats treated with higher dose of VPA added with PB or not,there were no significant elevations of liver enzymes(ALT and AST).However significant abnormalities of function of blood coagulation and serum fibrinogen were shown, and the levels of plasma ammonia and L-carnitine were also changed significantly,and the changes were notable in infant rats or in those rats added with PB. ② Average contents of cytochrome aa3 in liver mitochondria of infant rats were reduced by 58.80% and 61.80% because of administration of high dose VPA and high dose VPA added with PB,but were reduced by 37.55% and 46.53% in adults.As for activities of SDH,which affected by high dose VPA in infants,were significant decreased by 44.8% and 57.9%,respectively,but still in normal range in adult groups.Activities of CCO in liver mitochondria were significantly lowered by high dose VPA or added with PB compared with controls(P

Objective To investigate the clinical features of rheumatoid arthritis (RA) associated with thyroid function abnormalities.Methods Serum thyroid function,anti-thyroglobulin antibodies (TGAb) and anti-thyroid peroxidase antibodies (TPOAb) were detected in 186 RA patients.Clinical data were then analyzed.Comparison of continuous data between groups was made by t test,while comparison of categorical data was made by x2 test.The non-normal distribution of the data was analyzed by Mann-Whitney U rank sum test.Results Fifty-six RA cases (30%) had abnormal thyroid function,including 25 low T3 syndrome cases,16 subclinical hypothyroidism cases,10 hypothyroidism cases and 5 Graves' disease cases.Among them 23 cases were diagnosed as Hashimoto's thyroiditis.The positive rate in the hypothyroidism group with chills (45 cases,80.3%,x2=99.94),lazy words (14 cases,25.0%;x2=7.896),lethargy (24 cases,42.9%;x2=7.433) and abdominal distension (21 cases,37.5%;x2=7.15) was higher than that in the group with normal thyroid function (all P<0.05).Level of serum high density lipoprotein was decreased in hypothyroid group [(1.0±0.5) mmol/L vs (1.4±0.6) mmol/L,t=4.087,P<0.05].Patients with abnormal thyroid function had higher positive rate of ANA [(10 cases,7.7%) vs (25 cases,44.5%),x2=34.98],anti-SSA [(3 cases,2.3%) vs (23 cases,41.1%),x2=48.91],anti-SSB [(2 cases,1.5%) vs (12 cases,21.4%),x2=22.25],TGAb [(20 cases,15.4%) vs (43 cases,76.7%),x2=65.88] and TPOAb [(13 cases,10.0%) vs (27 cases,48.2%),x2=35.90] than those with normal thyroid function (all P<O.05).Conclusion Rheumatoid arthritis is often accompanied by thyroid disease.The positive rate of auto-antibodies in RA with abnormal thyroid function is higher than those with normal thyroid function and has no relationship with the disease activity.

Objective:To study the short-term effects,toxic side effects and immune function of Aidi injection adjuvant GP methods chemotherapy for advanced non-small cell lung cancer(NSCLC).Methods:130 patients with advanced NSCLC were divided into study group and the control group according to treatment methods.The study group were given Aidi injection +GP,and the control group only treated with GP.The short-term effects,toxic side effects gradeⅢ-Ⅳand immune function changes were compared between the two groups.Results:The overall response rate was 40.28%in study group,higher than 37.93% in control group(P>0.05).The two groups showed differences in the rates of leucocyte decrease,gastrointestinal reaction and platelets decrease(P<0.05).The levels of CD4,CD8 and CD4/CD8 didn′t changed obviously in study group(P>0.05),while in the control group the levels of CD4,CD8 and CD4/CD8 changed more significantly than before(P<0.05).The two groups also produced differences in CD4,CD8 and CD4/CD8 after treatment( P<0.05 ) .Conclusion: The short-term effects of Aidi injection adjuvant GP chemotherapy regimen for advanced NSCLC is similar to only GP chemotherapy,but it can obviously reduce the incidence of toxic side effects and prevent the immune func-tion.

BACKGROUND:Hydrothermal condition of oral environment has an effect on the mechanical properties of dental core materials.
OBJECTIVE:To evaluate effect of water storage on the weight change rates and flexural properties of three dual-cure core buildup composite resins.
METHODS: Rectangular specimens (25 mm×2 mm×2 mm) were prepared from three dual-cure core buildup composite resins (LuxaCore Smartmix Dual, Para core and Clearfil DC Core). Specimens were stored in distiled water at 37℃ for 0, 1 day, 1, 2, 3 weeks and 1 month, respectively, weighted and then subjected to three-point bending test in a universal testing machine.
RESULTS AND CONCLUSION: Weight change rates of the three composite resins increased with immersion time; at the same immersion time, weight change rates of three composite resins ranked as the folowing order: LuxaCore Smartmix Dual > ParaCore > Clearfil DC Core. The flexural strength of LuxaCore Smartmix Dual decreased with immersion time. The flexural strength of ParaCore showed no significant change during 3 weeks immersion (P > 0.05), while it showed a significant decreasing after 1 month immersion (P < 0.05). There was no significant change on the flexural strength of Clearfil DC Core in the whole immersion process(P > 0.05). The flexural modulus of LuxaCore Smartmix Dual showed a decreased trend in the whole immersion process, but it showed that there was no significant change during the first 2 weeks(P > 0.05), while a significant decrease occurred after 3 weeks and 1 month (P < 0.05). Compared with original specimens, the flexural modulus of ParaCore and Clearfil DC Core showed a decreased trend, but this change was not significant (P > 0.05); the flexural properties of three composite resins showed a fluctuant decreased trend along with weight changes increased. To sum up, Clearfil DC Core showed the best water resistance among three composite resins.
