Objective To investigate the effect of different dose of dexmedetomidine for pre-venting the visceral traction reaction during caesarean section under spinal anesthesia.Methods Two hundred ASA physical status Ⅰ-Ⅱ patients,full-term primiparas scheduled for elective cesarean sec-tion were enrolled in this randomized,placebo-controlled study.Patients were randomly allocated to receive dexmedetomidine in four groups:group C (0.9% normal saline),group D1(dexmedetomidine 0.6 μg/kg),group D2(dexmedetomidine 0.8 μg/kg),group D3 (dexmedetomidine 1.0 μg/kg),50 cases in each group.Two minutes after cutting umbilical,groups D1,D2,D3 received an intravenous infusion single-dose of 0.6,0.8,1.0 μg/kg dexmedetomidine respectively for 10 minutes.Group C was injected the same dose of saline.Maternal blood pressure (BP),heart rate (HR),Ramsay scores,visceral traction reaction conditions were recorded at three points:before iv (T0 ),10 min af-ter iv (T1 )and abdominal exploration (T2 ).Results As for the inhibition of visceral traction pain, groups D2 and D3 were obviously better than groups D1 and C,and there was no statistically signifi-cant difference between groups D2 and D3 at T2 (P <0.05 ).The effects of slowing down heart rate and increasing blood pressure were weaker in group D2 than that in group D3 at T2 .Ramsay scores were higher in groups D2 and D3 than in groups D1 and C (P <0.05),and there was no significant difference between groups D2 and D3 at T2 .Conclusion Administration of dexmedetomidine 0.8 μg/kg could alleviate the visceral traction reaction and had little effect on maternal hemodynamics.

Background:Primary biliary cirrhosis( PBC ) is an autoimmune liver disease,the cause of the disease remain incompletely understood. In addition to genetic and environmental factors,autoantibodies,multiple immunocytes and cytokines are considered to be involved in the development of PBC. Recent studies indicated that interleukin-9(IL-9)had pleiotropic functions in inflammatory regulation in allergic and autoimmune diseases. Aims:To investigate the expression and clinical significance of IL-9 in patients with PBC. Methods:A total of 30 specimens of peripheral blood and 20 specimens of liver tissue from PBC patients were collected. Ten specimens of peripheral blood from healthy subjects and 4 specimens of normal liver tissue were served as controls. Level of serum IL-9 was determined by ELISA,and expression of IL-9 in liver tissue was detected by immunohistochemistry. Correlations between IL-9 and serum biochemical indicators, immune indicators and histologic stage of liver tissue were analyzed. Results:Level of serum IL-9 was significantly increased in PBC patients than in normal control group(P<0. 05),and was positively correlated with level of serum IgG (r=0. 681,P<0. 01). Amount of IL-9 positive cells in liver tissue was significantly increased in PBC patients than in normal control group(P <0. 01),and was positively correlated with histologic stage of liver tissue(rs =0. 465,P <0. 05). Conclusions:Expression of IL-9 is significantly increased in peripheral blood and liver tissue in patients with PBC and is positively correlated with level of serum IgG and histologic stage of liver tissue,which suggests an important role of IL-9 in the pathogenesis of PBC.

Objective To investigate the relationships between mindfulness,anxiety and depression in surface warship soldiers and the mediating role of attentional control.Methods Chinese versions of State-Trait Anxiety Inventory ( STAI ) , Center for Epidemiologic Studies Depression Scale ( CES-D ) , Attentional Control Scale ( ACS) and the Five Facet Mindfulness Questionnaire ( FFMQ) were used to survey 475 sur-face warship soldiers. Single factor analysis of variance,correlation analysis and path analysis were conducted by SPSS 20.0 and Amos18.0. Results ①The scores of the state anxiety,trait anxiety and depression in the soldiers and noncommissioned officers were significantly higher than that of commissioned officers (P<0.05) . As for the state anxiety,trait anxiety,depression and attentional focusing,there were statistically significant differences among different educational levels (P<0.05) . Specifically,the lower educational level,the higher anxiety and depression,the lower control focusing. ② There were significant positive correlations among at-tentional focusing (27.12±4.43),attentional shifting (29.43±3.78) and mindfulness (120.27±11.16,r=0.49-0.51,P<0.01). State anxiety (38.65±10.07) was negatively correlated with attentional focusing,atten-tional shifting and mindfulness (r=-0.32--0.54, P<0.01). Similar results were observed for trait anxiety (41.28±8.79) and depression (9.97±10.13). ③Attentional focusing partially mediated the relationships be-tween state anxiety,trait anxiety,depression and mindfulness. Conclusion Anxiety and depression of sol-diers have obvious relationships with kinds of soldiers' rank and education level. Mindfulness and attentional control are vital protective factors for marine army's mental health. This study indicates that mindfulness may improve individuals' attentional focusing and attentional shifting,and ameliorate negative moods such as anx-iety and depression.
