Objective:To investigate the relationship between college students' perfectionism and their mental health,and parental rearing styles.Methods:The present study was a cross-sectional design.Three hundred and thirty seven Chinese college students(152 males and 185 females;aged 16～24) were recruited through cluster sampling.Participants were from three major universities,and responded to the revised Perfectionism Scale for Chinese College Students,Egna Minnen av Barndoms Uppfostran(EMBU),and SCL-90.Results:The group with high score in perfectionism also got higher scores in their perception of fathers' over-protection,over-intervention,and refusal/denial than the low score group [(2.4?0.5) vs.(2.0?0.4),(2.2?0.4) vs.(2.0?0.3),(1.5?0.5) vs.(1.4?0.5);P

Objective: To revise Frost's Multidimensional Perfectionism Scale (FMPS) within a sample of Chinese college students based on clinical knowledge and Hewitt & Flett's perfectionism questionnaire.Methods:Three hundred and fifty college students responded to the inventory with additional 15 items to the FMPS. Exploratory factor analysis was applied to the data. Results: The revised Perfectionism Scale consisted of 50 items, four subscales (Concerns with Mistakes and Doubts, Personal Standards, Organization, Parents' Expectation and Control). Factor analysis indicated that, the four factors explain 42.31% of the variance with loading between 0.37~0.79. The five subscales had internal consistencies with split-half reliabilities 0.73~0.88, Cronbach's alphas 0.80~ 0.91, and test-retest reliabilities of 0.68~0.80 (P

Objective To investigate the changes in cerebral oxygen metabolism during liver transplantation in patients with liver cirrhoses.Methods Sixteen ASAⅢorⅣpatients with liver cirrhoses(14 male,2 female)aged 25-67 yrs,weighing 45-80 kg undergoing liver transplantation were studied.Radial artery was cannulated for direct BP monitoring and blood sampling.Swan-Ganz catheter was placed in pulmonary artery (PA)via right internal jugular vein(IJV)for cardiac output(CO)monitoring and sampling mixed venous blood. Left IJV was cannulated and the catheter was advanced cephalad until jugular bulb for blood sampling.Anesthesia was induced with midazolam,fentanyl,propefol and vecuronium and maintained with isoflurane inhalation and intermittentⅣboluses of fentanyl and vecuronium.The patients were mechanically ventilated after tracheal intubation.PaCO_2 was maintained between 30-45 mm Hg.Blood samples were taken from radial artery,pulmonary artery and jugular bulb simultaneously for blood gas analysis before operation(T_0,baseline),10 min before anhepatic phase(T_1)20 min after onset of anhepatic phase(T_2),30 min after graft reperfusion(T_3)and at the end of operation(T_4).Oxygen delivery(DO_2),oxygen consumption(VO_2),oxygen content of jugular bulb blood (CjvO_2),cerebral arterial-venous oxygen content differences(Ca-jvO_2)cerebral oxygen extraction ratio(CERO_2) and CBF/CMRO_2 were calculated.Results The mean duration of operation was(364?51)min and the mean intraoperative blood loss was(1340?430)ml.CO was significantly increased before anhepatic phase(T_1), during neohepatic phase(T_3)and at the end of operation(T_4)but decreased during anhepatc phase(T_2)as compared with the baseline value at T_0.Hb,CaO_2,Ca-jvO_2 and CERO_2 were all decreased while SjvO_2 and CBF/ CMRO_2 were increased during operation;DO_2,VO_2 and CjvO_2 were decreased during anhepatic phase;DO_2 was increased during other phases;VO_2 was increased at the end of operation as compared with the baseline(T_0)(P＜0.05 or 0.01).Conclusion There is no cerebral oxygen deficiency during liver transplantation in patients with liver cirrhoses.

Objective To investigate the changes in systemic and pulmonary hemodynamics in patients with liver cirrhosis and portopulmonary hypertension(PPH)during liver transplantation.Methods Eight patients with liver cirrhosis and PPH(5 male,3 female)aged 50-63 yr weighing 45-80 kg were included in PPH group. Another 8 liver-cirrhotic patients without PPH served as control group.The patients were premedicated with intramuscular phenobarbital 0.1 g and atropine 0.5 mg.Anesthesia was induced with midazolam 3-5 mg,fentanyl 0.15-0.2 mg,propefol 1 mg?kg~(-1) and vecuronium 0.1 mg?kg~(-1) and maintained with 0.5%-3% isoflurane inhalation and intermittent Ⅳ boluses of fentanyl and vecuronium.The patients were mechanically ventilated after tracheal intubation.P_(ET)CO_2 was maintained at 30-45 mm Hg.Right subclavian vein was cannulated for fluid and drug administration and blood transfusion.Radial artery was cannulated for BP monitoring.Swan-Ganz catheter was placed via right internal jugular vein.BP,CVP,MPAP,PAWP,CI,PVRI and SVRI were monitored and recorded before operation(baseline),during preanhepatic phase,at 3 and 30 min of anhepatic phase and 3,7, 15,60 min of neohepatic phase and at the end of operation.Results(1)The two groups were comparable with respect to fluid balance,the amount of vasoactive drugs used during anhepatic and neohepatic phase,duration of anhepatic phase and operation.(2)MPAP and PVRI were significantly higher before operation in PPH group than in control group.(3)CI,MPAP, PAWP and CVP were siguificanfly decreased during anhepatic phase as compared to the baseline values(before operation)in both groups and then gradually returned to and even exceeded the baseline values during neohepatic phase.(4)During neohepatic phase PVRI in PPH group was significantly increased as compared to the baseline value and was significantly higher than that in control group.Conclusion MPAP and PVRI are significantly increased during neohepatic phase in patients with PPH and need to be treated.

Objective To characterize the molecular characteristics of hemagglutinin (HA) and neuraminidase (NA) of influenza B viruses isolated in Jiangsu province,2011.Methods Thirteen strains of influenza B virus in different areas and epidemic period in Jiangsu province,2011 were selected for whole-genome sequencing,and analysis of molecule epidemic characteristics for HA and NA was carried out by bioinformatics method.Results Of the 13 randomly selected influeuza B strains,10 strains were assorted to Victoria lineage strains with NA genes from Yamagata lineage,and 3 strains belong to Yamagata lineage.Compared nucleotide and amino acid sequences of HA and NA genes with their vaccine strains respectiuely,196/197 glycosylation site appeared on HA1 gene in Yamagata/Victoria isolates virus.Conclusion Both B/Victoria and B/Yamagata lineage viruses co-circulated in Jiangsu province,and reassortant virus of Victoria lineage were predominant virus.

To investigate the dynamics of interleukin-21 (IL-21) cytokine in the Chinese HIV patients undergoing highly active antiretroviral therapy (HAAPT).Methods A total of 25 adults with chronic HIV infections,responding to combined highly active antiretroviral therapy (HAART) guideline criteria were enrolled for a 1-year follow-up.After signing an informed consent,20 mL blood was collected from each patient at the base line,6 month and 12 month,respectively.CD4 and CD8 cell count was quantified by flux cytometry,serum HIV RNA quantified by real time PCR and IL-21 concentrations by ELISA.Results IL-21 levels increased gradually during the follow-up but did not reach the healthy levels.IL-21 correlated positively with the CD4 cells but not with CD8 T cells.HIV RNA correlated negatively with CD4 cell count but did not show any relationship with the CD8 cells.Conclusion IL-21 has potential role in the immunopathogenesis of HIV,and might be an important factor in immune construction during HAART.

Objective:To analyze the activities of human NKG2D ligand MICA/B promoter induced by 5-Fu.Methods:The 5'-end flanking regions of MICA /B promoter and their different truncated fragments were amplified from A549 genome by PCR. The resulting amplicons were cloned into pGL3-Basic vector to generate the MICA/B luciferase reporter plasmids. All the constructs were transiently transfected A549 cells. The promoter region activities were determined by dual-luciferase reporter assays. The effect of 5-Fu on the promoter activities of MICA/B was also tested.Results and Conclusion:The 5'-end flanking regions of MICA /B promoter and five of their different truncated fragments were successfully obtained. The normalized luciferase reporter gene activities driven by the above promoters and fragments were 3.61,2.26,1.63,0.313,0.711 and 0.663 for MICA and 17.49,10.11,7.398,0.822,0.997 and 0.49 for MICB,respectively. Promoter activities in transiently transfected A549 cells treated by 20,40,80,160 and 320 μg/m of 5-Fu increased 1.69,1.48,1.62,1.55 and 1.78 fold for MICA and 1.44,1.87,1.38,1.19 and 1.25 fold for MICB. Our results suggest that 5-FU can significantly up-regulate the promoter activity of both MICA and MICB.

Objective To investigate the current status of coal-burning endemic fluorosis and the fluoride content in foods and drinking water in Hongya County,Sichuan Province.Methods Dental fluorosis and urinary fluoride were suveyed in children of 8～12 years old in two schools which repectively located in Gaomiao and Wawushan Town.The adults above 20 years old underwent clinical examination.At the same time,fifty adults above 20 years old in Garden Village were chosen to take forearm and calf X-ray films to find out the evidence of skeletal fluorosis.The content of fluoride in food such as bacon,corn,dry capsicum in Sanxing Village in Gaomiao Town and Futian Village in Wawushan Town as well as drinking water in five families in Sanxing Village were determined.Results The dental fluorosis rate of children was 40.76%(161/395),the dental fluorosis index was 0.86 in Gaomiao Town.The dental fluorosis rate of children was 14.36%(82/571),the dental fluorosis index was 0.31 in Wawushan Town.The medium value of the urine fluoride was 0.81 mg/L.ranged 0.16～3.89 mg/L.The positive rate oi the clinical examination of skeletal fluorosis was 5.27%(27/512),the X-rays detective rate was 4.00%(2/50).The medium value in bacon,corn,dry capsicum were 6.00,0.64,1.49 mg/kg.The averaged content of the fluoride in drinking water(0.14±0.06)mg/L of local household was within the eligible limitation.Conclusions It is currently a mild endemic disease in Hongya Country,its incidence is reduced apparently,pathogenetic environmental fluoride content is reduced.The main source of fluoride is from the preserved ham contaminated with fluoride,which is epidemiologically significant in endemic area of Hongya County.Defluoriding countermeasures should be taken in the endemic areas.
