Objective To explore the effect of cognitive behavior intervention on the defense style of patients with depression. Methods One hundred and forty-six patients with depression in hospitalized were divided into study group and control group according to the set sequence. The study group and the control group were given cognitive behavioral intervention and routine nursing, respectively. All patients were assessed by Hamilton depression scale (HAMD), Hamilton anxiety scale (HAMA), Simplified Coping Style Questionnaire (SCSQ), and Defense Style Questionnaire (DSQ) . Results The differences of conceal type and positive coping factor were significantly before and after intervention in the study group ( < 0.05) . In the 6th week, the differences of conceal type and positive coping factor were significantly between the two groups ( < 0.05) . The differences of HAMD and HAMA scores were significantly between the 0 th and 6 th weeks of the two groups ( <0.05) . There was negatively correlated between HAMD and positive coping factor ( <0.05) . There were positively correlated between HAMD and the cover up defense mode ( <0.05),HAMA and the cover up defense mode ( <0.05) . Conclusion The cognitive behavior intervention could improve the depression and anxiety symptoms and defense style in patients with depression.

Objective To observe the dynamic changes in matrix metalloproteinase-12(MMP-12) expression during the course of development of radiation pulmonary injuries in order to get an insight of the roles played by MMP-12 during early tissue remodeling after radiation pulmonary injuries.Methods Twenty-four Wistar rats were randomly assigned into four groups(6 each): normal control group and 1,2 and 4 weeks after irradiation groups.The rats in the last three groups received irradiation of the whole lung with 20Gy of 60Co ?-ray,and they were sacrificed 1,2 and 4 weeks post irradiation.The gene expression of MMP-12 was determined by RT-PCR;the protein expression was detected by Western blot;MMP-12 activity was examined by gelatin zymography;the tissue distribution of MMP-12 was observed by immunohistochemistry;the degradation and collapse of elastin were observed after tissue elastin specific staining.Results The gene expression of MMP-12 began to increase 1 week post irradiation,then decreased at 2 weeks,and it reached its peak value at 4 weeks,while its protein expression was elevated again 2 weeks post irradiation.MMP-12 was mainly expressed in macrophages and activated fibroblasts of the alveolar septum.With the elapse of time,the lung injury aggravated gradually,with thickening of alveolar wall and septum,breakdown of the structure of alveoli,collapss of a part of the alveolar space,extensive breakdown of elastin in the basement membrane of lung,appearing as irregular fibrils distributed in the lung.Conclusion 60Co ?-ray irradiation can up-regulate the expression of gene and protein of MMP-12 significantly,implying that it may play a very important role in early remodeling process in of radiation pulmonary injuries,and initiate the process of pulmonary remodeling by degrading elastin and destroying the normal structure of basement membrane.

Objective To investigate the technical charactenstics ot SYSMEX XS1000i 5-part differential automated hematological analyzer and its clinical applications.Methods 209 samples were analyzed with the analyzer of XS1000i and compared to the results from Beckman-Coulter LH750 analyzer.The main parameters from XS1000i,such as precision within-run,day to day precision and carryover contamination rates etc,were recorded respectively in 509 samples to compare the difference between the instrumental and optical examination.Results All variation coefficients of precision from XSI000i were within the manufacturer.The carryover contamination rates of WBC,RBC,Hb,HCT and PLT were 0.19%,0.93%,0,-0.88%,-0.76%,respectively.The parameters of XS1000i were correlated with the results of LH750 except basophil granulocyte.The correlation coefficients of WBC,RBC, HGB and PLT were 0.994 5,0.996 8,0.997 0 and 0.974 6 ,respectively.The sensitivity of warning flags in immature leukocytes was 100% and the specificity was 69.7%,the sensitivity of warning flags in atypical lymphocyte was 100% and the specificity was 66.7%.Especially in 3 leukocytopenia that was induced by chemotherapy in patients with leukemia who had only few immature cells existed in the peripheral blood,the parameters of XS1000i were positive,and correlated with the results of detection of minimal residual disease with flow cytometry.Conclusions The warning system of XSIO00i provides more valuable information for manual microscopic examination.If it is combined with flow cytometry,the advantages in detection of residual leukemic cell will be fully displayed.

Objective To study the influence of cognitive behavioral intervention on the quality of marriage and family function in patients with depression. Methods 146 hospitalized patients with depression were divided into study group and control group according to the set sequence. The study group were given cognitive behavioral intervention and the control group were given routine nursing.All patients were assessed by Hamilton depression scale (HAMD), Hamilton anxiety scale (HAMA), family functioning (FAD), marriage quality questionnaire (ENRICH) to evaluate the depression and family function. Results The difference in ENRICH total score, marital satisfaction, conflict resolution, children and marriage, leisure activities and the relationship with family and friends,FAD total score, problem solving, emotional response was statistically significant between before and after the intervention of the study group ( <0.05) . In the 6th weeks, the difference in ENRICH total score, marital satisfaction, conflict resolution methods, children and marriage,leisure activities and the relationship with family and friends, FAD total score, problem solving,emotional response was statistically significant between the two groups ( <0.05);The difference in HAMD,HAMA score was statistically significant between the 0th and 6 th weeks of the two groups ( <0.05) . There was a negative correlation between HAMA and conflict resolution factor (=-0.48, <0.05) . There was a positive correlation between FAD and the HAMD total score (=0.43,<0.05) . There was a negative correlation between ENRICH and HAMD total scores (r=-0.46, <0.05) .Conclusion The cognitive behavioral intervention can improve the family function and the quality of marriage in patients with depression.

Objective To evaluate the correlation of intrahepatic HBV DNA load with the HBV load in serum and peripheral blood mononuclear cells(PBMC)and the stage of fibrosis,grade of inflammation,level of serum ALT and AST.Methods Liver specimens were taken from 50 patients by percutaneous needle biopsy and divided into two parts:one was processed for histological examination,and the other was used for molecular biology analyses.HBV DNA load was measured with fluorescent quantitative polymerase chain reaction(FQ-PCR).The data of serum level of ALT and AST were collected.Results A high correlation between intrahepatic HBV-DNA load and serum virus load was found(r=0.77977,P

Objective To investigate the influence of arsenic trioxide (AS2 O3 )in the vasculogenic mimicry (VM ) of HepG2 cells, and to preliminary clarify the possible mechanism of inhibition of AS2 O3 on the VM. Methods Themean inhibitory concentration (IC50 )of AS2 O3 72 h after treatment of HepG2 cells was calculated by CCK-8 assay.The HepG2 cells were cultured on 3-D Matrigel and randomly divided into control group, 1/2 IC50 AS2 O3 group and IC50 AS2 O3 group.IPP software was used to calculate the number,length and area of VM,and the expression levels of VM-related proteins VE-cadherin and MMP-2, apoptotic-related protein caspase-3 and proliferation-related protein PCNA were detected by Western blotting method.Results The IC50 of AS2 O3 was 10μmol·L-1 72 h after treatment of HepG2 cells.The number,length and area of VM in 1/2 IC50 and IC50 AS2 O3 groups were significantly lower than those in control group (P<0.01);the number,length and area of VM in IC50 AS2 O3 group were also lower than those in 1/2 IC50 AS2 O3 group (P<0.05).Compared with control group,the expression levels of VE-cadherin and MMP-2 in 1/2 IC50 and IC50 AS2 O3 groups were decreased (P<0.05),and the expression levels of caspase-3 and PCNA had no significant change (P>0.05).Conclusion AS2 O3 can inhibit the forming of VM of HepG2 cells,which indicated that its mechanism may be related to inhibiting the expressions of VE-cadherin and MMP-2 .

Epicatechin content in Uncaria macrophylla Wall. was determined by RP-HPLC. As aresult, the epicatechin contents were 0.38％ in the hook and stem, and 0. 820％ in the leaf. Thus it seemedto be more worthwhile to produce epicatechin from the leaf rather than from the hook and stem.
