ObjectiveTo investigate the relationship among social support,coping style and mental health on university librarians.Methods421 librarians were assessed with the symptom checklist 90 (SCL-90),social support rating scale (SSRS) and simplified coping style questionnaire (SCSQ) in 2005. ResultsSome factor of SCL-90 negatively correlated with utility percentage of social support(P<0.05), and positively correlated with passive coping style(P<0.05). Except utility percentage,the other three factors of social support showed significant difference among different academic titles (P<0.05), and it was significant different (P<0.05) on passive coping factor among them. The score of social support improved with ages except for utility percentage (P<0.05).On positive coping factor but not negative, there were significant difference among different age groups(P<0.05). ConclusionThe social support and coping style obviously correlate with the mental health of university librarians.

Membrane fusion is essential for all life activities of eukaryotes and the fusion process requires the interaction of different vesicular transporters,which are highly conserved in eukaryotes,to coordinate specifically and facilitate the fusion of different biofilms. Vesicle associated membrane protein 8(VAMP8)mainly locates in vesicular as well as lysosomal membranes,and plays a vital role in the fusion of many different biofilms. This paper focused on the molecular structure,transcriptional regulation,post-translational modification and biological function of VAMP8 as well as the research progress on its correlation with human diseases,so as to provide new ideas for the treatment of related diseases and the development of effective therapeutics targeting VAMP8.

ObjectiveTo explore the application of enlargement of plastic surgery for dural closure with radial neuro-patch in standardize large decompressive craniectomy (SLDC).MethodsTwenty-one patients (observation group) who needed a SLDC for various reasons were treated with radial incision in dura to release the high intracranial pressure and enlargement of plastic surgery for dural closure with radial neuropatch from March 2009 to June 2010.The neuro-patch were used as the dural substitutes.Twenty-one patients were treated with SLDC only for the similar reasons (control group).General healing effects were compared betweentwo groups.ResultsIn 6 hours and 72 hours after surgery,the rate of obvious effectiveness in observation group was significantly higher than that in control group [33.33％(7/21 ) vs.14.29％(3/21 ),33.33％(7/21 ) vs.19.05％(4/21 ) 、61.90％( 13/21 ) vs.28.57％(6/21 ),61.90％( 13/21 ) vs.38.10％(8/21 )](P ＜ 0.05).The rate of intracranial infection,cerebrospinal leak and epilepsy in observation group [0,0,4.76％ ( 1/21 )]was significantly lower than that in control group [14.29％ (3/21),14.29％ (3/21),19.05％ (4/21)](P ＜0.05).The rate of subcutaneous or subdural cerebrospinal fluid accumulation,cenencephalocele,cerebral ventricular malformation,brain hernia through the skull window had no significant difference between two groups [19.05％(4/21 ),0,4.76％( 1/21 ),0 in observation group;23.81％(5/21 ),9.52％(2/21 ),9.52％(2/21 ),4.76％( 1/21 ) in control group) (P ＞ 0.05 ).After followed up of 6-12 months,the rate of the well general outcome in observation group was significantly better than that in control group [85.71％ ( 18/21 ) vs.71.43％ ( 15/21 )](P ＜ 0.05 ).The rate of moderate-critical function handicapped in control group was significantly higher than that in observation group [23.81％(5/21 ) vs.9.52％(2/21 )](P＜0.05 ).ConclusionsThe SLDC is effective for decreasing the intracranial pressure,and the enlargement of plastic surgery for dural closure with radial neuro-patch can improve the efficiency and decrease the incidence of complicating diseases.This therapy can improve the patients' general quality of survival and is worth to be popularized in clinic.

Objective To find out the clinical outcomes of twin-twin transfusion syndrome (TTTS) after aminioreduction. Methods Twenty-nine pregnancies with TTTS delivered in Beijing Gynecological and Obstetric Hospital from Nov. 1, 2002 to Sept. 30, 2007 were recruited. The effect of gestational age at the onset, the degree of TTTS and amnioreduction therapy on the fetal outcomes were compared. Results All of the 8 cases with the onset of TTTS before 26 weeks without treat- ment were lost, but 4 out of the 6 with the onset after 26 weeks survived (P=0. 015). Among the 9 cases received amnioreduction, 4 out of the 5 with onset before 26 weeks survived, and significant difference was found compared to those untreated ones (P= 0. 007), but no difference was shown when compared with those developed after 26 weeks(4/4)(P= 1. 000). The average delivery weeks in the untreated ones was earlier than those received treatment E(28.7±4.7)weeks vs (33.2±4.9) weeks, P=0. 001]. Amnioreduction improved the umbilical cord blood flow. For severe TTTS(stage Ⅲ～Ⅳ) with the onset before 26 weeks, the survival rate after amnioreduction was significantly high- er than those untreated ones[4/5 vs 0/5, P=0. 048)]. Conclusions Aminioreduetion is effective in improving the cord blood flow, prolonging the pregnancies, and achieving a higher fetal survival rate.

Objective To investigate the effects of aerosolized Dexamethsone inhalation on circulatory and respiratory function during lung injury (ALI) induced by hydrochloric acid (HCI) aspiration.Methods Twenty-four healthy pigs of either sex,weighting (15.5±2) kg were anesthetized with intraperitoneal injection of pentobarbital sodium 50mg/kg and intubated and mechanically ventilated (FiO2=1.0,VT=10-15 ml/kg,RR=16bpm,I:E=1:2).Anesthesia was maintained with infusion of Ketamine,procaine and succinylcholine.Femoral artery was cannulated for MAP monitoring and blood sampling.Swan-Ganz catheter was placed in the pulmonary artery via right inexternal jugular vein.Dilute HC1 (0.1mol/L) was instilled via trachea into lungs until PaO2 was＜13.3kPa.Arterial blood gases,MAP,MPAP and dynamic compliance were measured before induction of ALl (T0),when ALI was induced (T1) and 1,2,3 and 4(T2～5)there after.The pigs were then divided randomly into three groups according to the treatment they received:group A received IPPV alone,group B IPPV+PEEP(0.69kPa) ,group C IPPV+PEEP(0.69kPa)+aerosolized Dexamethasone (12.5ugokg-loh-I).Results MAP decreased significantly after induction of ALI in three groups hut there was no significant difference in MAP among the three groups (P＞0.05).MPAP increased significantly after induction of ALI in all groups and remained high during the period of T2～5 in group A and B (P＞0.05),hut decreased significantly from T2 in group C (P＜0.05 ).PaO2 increased significantly during the treatment in group B、C(P＜0.05),and was significantly higher in group C than that in group B (P＜0.05).PaCO2 in group A was highest in three groups (P＜0.05) and group C was lower in three groups (P＜0.05).Dynamic lung compliance decreased in all animals after induction of lung injury (P＞0.05),but was gradually increasing significantly during treatment(B、C group) (P＜0.05).Conclusion Aerosolized Dexamethasone inhalation can improve respiratory function during ALI induced by HC1 aspiration and reduce pulmonary hypertension,but dont impair MAP.Both have the same effects on the treatment of lung injuries.
