Objective:To explore the moderating effect of self-differentiation between life events and coping styles. Methods:Totally 584 college freshmen from Beijing and Jiangsu were selected to fill in the Adolescent Self-Rating Life Events Check-list (ASLEC),Differentiation of Self Inventory(DSI)and Simplified Coping Style Ques-tionnaire (SCSQ). Results:Self-differentiation had a moderating effect between life events and coping styles. The predicting effect of life events on negative coping was 0. 03 in the higher self-differentiation group (P>0. 05 ) while in the lower self-differentiation group,it was 0. 27 (P<0. 00 1 ). Conclusion:It suggests that higher self-differ-entiation could relieve the negative effect of life events to coping styles.

Objective To compare the onset time, duration and adverse effects of stellate ganglion block (SGB) with different concentrations of lidocaine. Methods Two hundred and forty ASA Ⅰ or Ⅱ patients (97 male, 143 female) aged 37-76 yr weighing 48-79 kg were randomly divided into 3 groups ( n = 80 each): group A, B and C received unilateral SGB with 8 ml of 0.6%, 0.8% and 1.0% lidocaine respectively. Unilateral SGB was performed by the same anesthesiologist in all patients. Successful SGB was verified by Homer's syndrome. The onset time, duration and adverse effects were recorded. Results Homer's syndrome was observed in all patients. There was no significant difference in onset time among the 3 groups. The duration of action was significantly longer in group B and C than in group A and in group C than in group B. There was no significant difference in the adverse effects including recurrent laryngeal nerve block, brachial plexus block, local anesthetic intoxication and transient loss of consciousness among the 3 groups. Conclusion SGB can be induced with either 0.6%, 0.8% or 1.0% lidocaine with comparable effectiveness. We suggest using lower concentration of lidocaine.

Objective To investigate the effect of preconditioning with different concentrations of sevoflurane on hypoxia-reoxygenation(H/R)-induced apoptosis in rat hippocampal neurons and the role of mitochondrial KATP(mito-KATP)channels.Methods Primary cultured hippocampal neurons isolated from newborn SD rats(<24h)of both sexes,weighing 5-6 g,were randomly divided into 7 groups with 48 wells and 12 dishes in each one:control group(C group),H/R group,preconditioning with 6%,4%and 2% sevoflurane groups(S1-3 groups),5-hydroxydecanoate(5-HD,mito-KATP channel blocker)100 μmol/L preconditioning group(5-HD group)and preconditioning with 5-HD 100 μmol/L+6% sevoflurane group(5-HD+S group).The neurons were exposed to 4 h hypoxia followed by 24 h reoxygenation. In S1-3 groups, preconditioning was performed with 6% , 4% and 2% sevoflurane respectively before H/R. In 5-HD group, preconditioning was performed with 5-HD (final concentration 100 μmol/L) before H/R. In 5-HD + S group, preconditioning was performed with 5-HD 100 μmol/L and 6% sevoflurane before H/R. The neuronal viability, apoptosis rate and expression of Bcl-2 and Bax were determined after 24 h reoxygenation.Results The neuronal viability was significantly lower,while the apoptosis rate and expression of Bcl-2 and Bax were significantly higher in the other 6 groups than in group C(P<0.01).The neuronal viability and expression of Bcl-2 were significantly higher,while the apoptosis rate and Bax expression were lower in S1-3 groups than in group H/R. There was no significant difference in the parameters mentioned above between 5-HD and 5-HD + S groups(P>0.05).The neuronal viability and expression of Bcl-2 were significantly lower, while the apoptosis rate and Bax expression were higher in S2, S3 and 5-HD + S groups than in group S1, and in group S3 than in group S2(P<0.0l) .Conclusion Sevoflurane preconditioning can inhibit H/R-induced apoptosis in rat hippocampal neurons and reduce the injury to neurons in a concentration-dependent manner, and the underlying mechanism may be related to activation of mito-KATP channels, up-regulation of Bcl-2 expression and down-regulation of Bax expression.

Objective To investigate the different expression of microRNA-155 (miR-155) and cysteine-rich 61 (CYR61) in human placentas between severe preeclamptic and normal pregnancies.Methods Placentas were obtained from severe preeclamptic and healthy control pregnant women (n=18 for each group) at 36~40 gestational weeks. The expressions of miR-155 and CYR61 mRNA were assessed by real-time quantitative reverse transcription-polymerase chain reaction, and the levels of CYR61 protein were tested by Western blot. Results Compared with the control group, the miR-155 expression was increased in placentas from severe preeclampsia groups ( 165. 7 ± 16. 4 vs 527.9±49.1,t=7.00, P<0.01), and the CYR61 mRNA expression (31.7±2.7 vs 16.4±1.2,t=5.10,P<0. 01), as well as the CYR61 protein expression (36.4±1.5 vs 19.7±1.2,t=36.26, P<0.01 ) were decreased. There was a significantly negative correlation between the expression of miR-155 and CYR61 mRNA within both groups (preeclamptic group: r=-0.52, P<0.05;control:r=-0.57, P<0.05). Conclusions Up-regulation of placental miR-155 in severe preeclampsia may be related to the decreased expression of CYR61. Both miR-155 and CYR61 may contribute to the disorders of placental angiogenesis in severe preeclampsia in human.
