Objective To analyze the relationship between carotid intima-media thickness (CIMT) and metabolic syn?drome (MS), and explore risk factors for CIMT incrassation in Tianjin policemen. Methods Fifty MS patients (MS group) and 50 healthy people (control group) in health examination of Tianjin policemen were enrolled in this study. The question?naire survey(family history,past medical history,present history,living habits and occupational stress factors) were recorded in two groups of patients. The blood indicators (fasting plasma glucose, triglycerides, total cholesterol, high density lipopro?tein cholesterol, low density lipoprotein cholesterol, homocysteine) were detected. The color Doppler was used to measure CIMT incrassation, and incrassation ratio was calculated. The relative indicators were compared between two groups. The lo?gistic regression model was used to analyse the influencing factors of carotid artery intima-media thickness. Results CIMT and CIMT incrassation ratio (communis, internal and external carotid) were significantly higher in MS group than those of control group (P<0.01). The risk factors for CIMT included family history of hypertension, chronic stress, smoking, family history of diabetes, high fat diet and high homocysteine levels, and dairy products were protective factors for CIMT incrassa?tion. Conclusion The reason of carotid artery intima-media thickness is diversity. The healthy lifestyle and clinical inter?vention to retard CIMT are advocate, which are conducive to the control of atherosclerosis.

Dengue virus (DENV) is a re-emerging disease transmitted by the Aedes mosquitoes and has become a major public health problem in southern China. Currently, no antiviral drug or effective vaccine exist to control this disease. The chimeric DENV structural protein vaccine cannot elicit balanced levels of protective immunity to each of the four viral serotypes; therefore, non-structural protein components may be required to construct an effective DENV vaccine. The Dengue virus non-structural 1 (DENV NS1) protein plays a critical role in viral pathogenesis and protective immunity. Therefore, immunity to Dengue 1-4 NS1 subtypes may be crucial for the prevention of severe disease. This review attempts to provide an overview about the structure and function of DENV NS1.

ObjectiveTo investigate the roles of 11 β-hydroxysteroid dehydrogenase type 1 ( 11 β-HSD1 )on hippocampus of rat with chronic unpredictable mild stress (CUMS).MethodsTwenty-four male SpragueDawley rats were randomly divided into control group and depressive model group. Chronic unpredictable mild stress (CUMS) was used to make up depressive animal model.Behavioral changes were recorded by body weight measuring,sucrose consumption test (SCT) and open field test (OFT),respectively.The mRNA transcription of 11β-HSD1 in hippocampus tissues of the rats were detected by real-time RT-PCR,and the protein expression of 11β-HSD1 were detected by western blot and immunofluorescence.ResultsBcforc starting CUMS protocol,the rats exhibited equivalent weight and sucrose consumption.Twenty-eight days after CUMS protocol,behavior parameters such as body weight,sucrose consumption,nunber of crossing,and number of rearing were significantly decreased in rats exposed to CUMS group compared with control group (P ＜ 0.05,P ＜ 0.01 ).Correspondingly,realtime RT-PCR assays showed the mRNA expression of 11 β-HSD1 in the hippocampus of CUMS group,which was (31 ±9) ％ lower than that of control group.Meanwhile,the protein expression of it in CUMS group was lower than that of control group (P ＜ 0.05 ).Inmunofluorescence revealed that the number of positive 11 3-HSD1 cells was high (223 ± 13) in the control group,while the number was decreased prominently (92 ± 11 ) in the CUMS group (P ＜ 0.01 ).ConclusionDepressive behavior of rats is induced and the expression of 11 β-HSD1 in the hippocampus is decreased prominently by CUMS,the mechanism of which is at least related to the low expression of 11β-HSD1 and disturbance of glucocorticoid metabolism caused by CUMS.

Objective To investigate effects of intrathecal methotrexate on mechanical allodynia in rats with tibial bone cancer pain.Methods Forty-eight female SD rats weighing 150-180 g were randomly divided into 6 groups ( n =8 each):group Ⅰ sham operation + artificial cerebrospinal fluid(SA group),group Ⅱ sham operation + methotrexate 200 μg(SM group),group Ⅲ bone cancer pain + artificial cerebrospinal fluid(CA group),group Ⅳ-Ⅵ bone cancer pain + different doses of methotrexate (CM1-3 groups).The model of tibial bone cancer pain was induced by injecting Walker-256 cell into the tibial marrow cavity.CA and CM1-3 groups were intrathecal injected artificial cerebrospinal fluid,methotrexate 50,100 and 200 μg.SA and SM200 groups were intrathecal injected artificial cerebrospinal fluid and methotrexate 200 μg.The mechanical withdrawl threshold (MWT) was measured at day 1 before Walker-256 injection (baseline),7 day after injection (T0 ) and 2,4,8,24 hour and 1,3,5,7 days after intrathecal injection ( T1-8 ).Results Compered with the baseline,MWT was decrease in CA and CM1-s groups.Competed with To,MWT was decreased at T5-8 in CA group,MWT was increased at T3-5 in CM1 group,at T2-6 in CM2 group and at T2-7 in CM3 groups.MWT was decrease in CA and CM1-3 groups as compered with SA group; MWT was increased at T4-7 in CM1 group and at T3-7 in CM2 and CM3 groups.Conclusion Intrathecal injection of methotrexate can reduce tibial bone cancer pain in rats.

Objective To investigate the role of chemokine ligand 21 (CCL21) in the spinal cord in tibia bone cancer pain (BCP) in rats.Methods Forty adult female SD rats weighing 160-180 g were randomly divided into 5 groups (n=8 each):sham operation group (group Ⅰ ); sham operation + CCL21 neutralizing antibody group (groupⅡ); BCP group (group [); BCP + PBS group (group Ⅳ); BCP + control IgG group (groupⅤ)and BCP + CCL21 neutralizing antibody group (group Ⅵ).BCP was induced by inoculating Walker-256 mammary gland carcinoma cells into the rat tibia medullary cavity in groups Ⅲ-Ⅵ.PBS 15 μl,IgG 10 μg and CCL21 neutralizing antibody 10 μg were injected intrathecally (IT) at 14 days after intra-tibial injection of Walker-256 mammary gland cancer cells in groups Ⅳ- Ⅵ respectively.Mechanical withdrawal threshold to yon Frey filament stimulation (MWT) was measured at 1 day before (To,baseline) ; 7 and 14 d after Walker-256 cell injection (T1,T2)and at 0.5,1,2,4,8,12,24 and 48 h after intrathecal injection (T3-10 ).Results Intra-tibial injection of Walker-256 mammary gland cancer cells significantly decreased MWT as compared with the baseline values in administration of CCL21 neutralizing antibody at T5-8 as compared with MWT before intrathecal administration at T2 in group Ⅵ.MWT was significantly lower in groups Ⅲ- Ⅳ than in groups Ⅰ and Ⅱ.MWT was significantly higher at T5-8 in group Ⅵ than in groups Ⅲ - Ⅴ.Conclu]sion CCL21 in the spinal cord is involved in the maintenance of tibia BCP in rats.
