The polymorphisms of paraoxonase 1 ( PON 1 ) and ApoE gene in 192 patients with type 2diabetes mellitus (DM group) , 116 cases of atherosclerosis (AS) without DM (AS group), and 105 normal subjects (NC group ) were detected by means of PCR-restriction fragment length polymorphism. The serum concentration of Ox-LDL was determined by enzyme linked immunosorbent assay. The results showed that plasma Ox-LDL level in DM group was higher than those in AS and NC groups[(754.2±279.9 vs 526. 1±186.2 and 421.1 ± 163.2 )μg/L, P<0.01]. Ox-LDL level in the patients with QQ genotype of PON 1 was higher than those in QR and RR genotypes in type 2 DM[(846.6±147.5 vs 763.4±126. 7 and 7 1 3.2 ±132.4 ) μg/L, P<0. 0l],and Ox-LDL level in the patients with ε3/4+ ε4/4 genotype of ApoE was also higher than those in ε3/3 and ε2/2 + ε2/3 geneotypes in type 2 DM[( 824.3 ± 173.5 vs 741.6± 182. 5 and 718.3 ± 167.5 ) μg/L, P<0.05], but the difference was not found in atherosclerosis without DM. Multiple regression analysis showed that disease duration, PON1 and ApoE genotypes were the independent predictors of plasma Ox-LDL level in patients with type 2 DM.

Objective To investigate the relationship between the polymorphisms of plasminogen activator inhibitor-1(PAI-1)gene and the level of endothelium-dependent vasodilatation (EDF) in patients with type 2 diabe- tes(T2DM).Methods The polymorphisms of PAI-1(4G/5G)gene were determined by polymerase chain reaction (PCR)and the EDF was assessed by non-invasive hish resolution B-mode ultrasonography in 66 T2DM patients and 33 controls.Plasma plasminogen activator inhibitor type-1(PAI-1)and fibrinogen(Fg)were measured.Results Frequencies of PAI-1 alleles and genotypes in T2DM patients and controls were all in accordance with the Hardy Weinberge quilibrium,without significant differences between T2DM patients and controls(P>0.05).PAI-1 and Fg were significantly higher in T2DM patients than in controls.There were significant differences in EDF and PAI- lamong different genotypes of PAI-1(P<0.05).Conclusion The PAI-1 genotype may affect EDF in T2DM pa- tients.

Objective To observe the changes of the endothelium-dependent vasodilatation(EDF)and serum vascular endothelial growth factor(VEGF)in the patients with impaired glucose tolerance(IGT)and type 2 diabetes mellitus(DM).Methods 30 IGT patients,30 type 2 DM patients and 33 normal subjects were divided into3 groups. Fasting glucose(FPG),fasting insulin(FINS),serum superoxide dismutase(SOD),maleie. dialdehyde(MDA)and VEGF were measured after 12 hours overnight fast. Oral 75g glucose tolerance test(OGTT)was performed. The inner diameter of braehial artery was assessed by a high resolution ultrasound system before and after reactive hyperemia. EDF was calculated as the percent change in brachial artery diameter 1 minute after reactive hyperemia compared with baseline. Results In the IGT group and DM group, EDF was significantly lower than that in NGT group(both P＜0.01),and EDF in the DM group was significantly lower than that in the IGT group(P＜0.01).SOD in the IGT group and DM group were significantly lower than that in the NGT group(both P＜0.01),but MDA in reverse(both P＜0.01).Compared with the IGT group, SOD in DM group was significantly lower(P＜0.01),but MDA was significantly higher(P＜0.01).VEGF was progressively increased in the NGT,IGT, DM groups. The difference between the two groups was significant(both P＜0.01).Stepwise regression analysis showed that EDF was positively related to SOD(r=0.418,P＜0.01,n=93),and negatively related to HOMA-IR and VEGF(r=-0.553,-0.221,both P＜0.01,n=93).VEGF was negatively related to SOD(r=-0.552,P＜0.01,n=93).Conclusion EDF is impaired in IGT patients while the impairment in DM patients becomes more marked. Insulin resistance, VEGF,SOD and MDA are closely related to the impairment of EDF in IGT and type 2 DM.

Salmonella is an important zoonosis.China is the largest pork consumer.Contaminated pork is the main source of Salmonella disease at home and abroad.There are many swine Salmonella vaccine in use in Europe.Now the current swine Salmonella vaccine is a live attenuated vaccine,Salmonella can reduce colonization in pigs,and can induce immune response efficiently after the two immunizations.The control effect is poor,at this stage of swine vaccine cross protection research,type of Salmonella and vaccine antigen are not the same.This paper reviews the research progress of swine Salmonella vaccine.

Plasma plasminogen activator inhibitor 1 (PAI-1) antigen level in 204 patients with type 2 diabetes mellitus (DM) was higher than that in 60 healthy subjects (P

Chronic neck pain is a common chronic musculoskeletal disorder. Research on neck muscle fatigue contributed to the understanding the pathogenesis of chronic neck pain. The influences caused by the neck muscle fatigue, such as the change of cervical proprioception and balance, could easily lead to chronic injury. Changes in morphology and recruitment strategy of cervical muscle could decrease muscle endurance, which bring about further damage. Targeted therapy and training can relieve muscle fatigue, improve muscle function, and reduce the recurrence rate. Surface electromyography has unique advantages in the evaluation of cervical muscle fatigue. The assessment of muscle fatigue could provide for assistance to the treatment and curative effect of chronic neck pain.

Objective To determine the immune responses induced by recombinant Salmonella ty-phimurium expressing the secreting antigen ESAT-6 of Mycobacterium tuberculosis. Methods ESAT-6 cod-ing gene was cloned and identified by PCR and sequencing. Prokaryotic expression plasmid pYA33-esat car-rying the ESAT-6 coding sequence was constructed firstly and electro-transformed into an attenuated strain X4550 of Salmonella typhimurium, the recombinant bacteria was named as X4550(33-esat). C57BL/6 mice were immunized intranasally (I. N) with 108 CFU recombinant bacteria at day 0 and 18. Cells from spleen, lung, mesenteric lymph node (MLN) and Peyer's patch (PP) were collected from mice after second immu-nization, and the specific IFN-γ-secreting cells and IL-4-secreting cells were detected by ELISPOT assay u-sing ESAT-6 peptide as stimulus. Furthermore, CTL effects were in vivo evaluated by CFSE assay. Results The results showed that cellular immune responses specific for ESAT-6 could be detected by ELISPOT assay. In lung and PP cells, immune responses against ESAT-6 were biased toward Th1 type, the frequency of IFN-γ-secreting cells was much higher than that of IL-4-secreting cells. In splenocytes and MLN cells, the anti-gen specific immune responses acted as Thl and Th2 balance, the frequency of IFN-γ-secreting cells was close to that of IL-4-secreting cells. CFSE assay indicated that recombinant bacteria could induce the high level of CTL effects specific for ESAT-6 peptide. Conclusion These results suggested that recombinant Sal-monella typhimurium X4550(33-esat) not only can induce cellular immune responses, but also can elicit specific CTL responses after I. N immunization. It also provided the useful information for the control of infec-tious disease of tuberculosis.

Two hundreds postmenopausal women with osteopenia, aged 45-80, were randomly divided into 4 groups, and received different drug interventions. After treatment for 12 months, the lumbar spine bone mineral density(BMD)and total hip BMD in alendronate group increased significantly(3.5% and 2.6%, both P＜0.05), the lumbar spine BMD raised 2.0% in selective estrogen receptor regulator group(P＜0.05). Bone turnover indices improved in both groups(all P＜0.05). No change in BMD or bone turnover indices was found in patients treated with active vitamin D3and calcium.

Objective To investigate the risk factors for postmenopausal osteoporosis in Shanghai.Methods Five hundred postmenopausal community-dwelling women aged 45-80 years were recruited. The case-control study was performed from June 2008 to September 2008.A total number of 250 women with postmenopausal osteoporosis identified with their bone mineral density (BMD) were selected as case group, and 250 non-osteoporosis women were selected as control group. BMD was measured by dual energy X-ray absorption (DEXA). Results Univariate logistic regression analysis showed that age, eduction level, occupation, years since menopause, BMI, use of calcium,historyofnon-violencefracture,fall,diabetesmellitus,chronicgastricdiseases, gastrointestinal resection and diarrhea were related to osteoporosis.Multiple logistic regression showed that age, years since menopause and nutritional status were the risk factors for osteoporosis. ConclusionsThe occurrence of osteoporosis is related with many factors in postmenopausal women in Shanghai, and women with early menopause, low BMI and older age should pay more attention to the prevention and treatment of osteoporosis.
