Objective To explore the relationships of post- traumatic growth with self- care efficacy and psychological resilience in patients with breast cancer. Methods Totally 303 patients with breast cancer were investigated with Post- traumatic Growth Inventory (PTGI), Chinese version of Strategies Used by People to Promote Health (C- SUPPH) and Connor- Davidson Resilience Scale (CD- RISC). Results The total score of PTGI was 63.74±13.00 and the status of post- traumatic growth in breast cancer patients was in middle level, with a highest interpersonal score of 24.49±5.05, a lowest mental change score of 3.84± 1.91. Correlation analysis showed that post- traumatic growth was positively correlated with the level of self- care efficacy and psychological resilience (P<0.01 or 0.05). Regression analysis showed that self- care efficacy and psychological resilience in breast cancer patients could effectively predict the post- traumatic growth with an explanation rate of 36.1%. Conclusions Self- care efficacy and psychological resilience in patients with breast cancer are closely correlated with post- traumatic growth. It is suggested to take appropriate measures to promote post-traumatic growth of the breast cancer patients.

Objective:To test the validity and reliability of Chinese version of Psycho-Educational Profile (C-PEP) for children with autism in order to develop an assessment tool suitable for Chinese autistic children.Methods:A sample of 438 children who were diagnosed as autism according to the Diagnostic and Statisti-cal Manual of Mental Disorders,Fourth Edition (DSM-IV)criteria and aged from 2 to 11 coming from four differ-ent medical or educational rehabilitation agencies of Beijing,Wuhan,Shenzhen and Changchun were selected.488 Children with 2 to 7 years old were sampled from ordinary kindergartens.This study examined the validity and reli-ability of C-PEP using autism sample.Construct validity was tested with the C-PEP by inter-subscale Pearson corre-lations and confirmative factor analysis.Criterion-related validity was tested with the Peabody Picture and Vocabula-ry Test (PPVT),Combined Raven Test (CRT),Adaptive Behavior Scale (ABS),Childhood Autism Rating Scale (CARS)and the age as criteria.Discriminate validity was obtained by comparing the differences between the typi-cal and autism samples with the total scores of C-PEP.Internal consistency and rater reliability of C-PEP were ex-amined by Cronbach α,ANOVA of rater variation and intra-class correlation coefficients.Results:The inter-sub-scale correlations of C-PEP were medium relevance,the subscale and domain correlations were relatively high.Confirmative factor analysis indicated a relatively high fitting index between the model and sample da-ta.Regarding the concurrent validity of the C-PEP,the development total score was significantly correlated with the Raven's IQ,PPVT IQ,and ADQ scores,pathological behavior total score was positively related to the CARS score.T test results showed that children with autism were significantly behind the typical children at all age lev-els.Results also revealed that the internal consistency based on coefficient alpha and the intra-class correlation coef-ficients of raters for all subtests of C-PEP were reliable.Conclusion:It suggests that the Chinese version of Psycho-Educational Profile (C-PEP)is of good validity and reliability,and it could be used as an effective tool for measur-ing children with autism.

Objective To investigate the effect of Janus kinase2/signal transducer and activator of transcription 1 (JAK2/STAT1) signaling pathway on acute kidney injury induced by liver cold ischemia reperfusion (IR) in rats.Methods Thirty healthy male Sprague-Dawley rats,weighing 220-250 g,were assigned randomly to 3 groups (n =10/group):sham operation group (Sham group);liver cold ischemia reperfusion model group (I/R group);JAK2 kinase inhibitor AG490 group (AG490 group) (AG490 at dose of 10 mg/kg was intraperitoneally injected 30 min before establishment of the model).Other groups were given the equal volume of normal saline at the same time points.Then the rats were sacrificed at 6 h after reperfusion (at 6 h after the end of operation in Sham group).The renal function and oxidative stress level were observed.The pathological changes of the renal tissues and nephritic cell apoptosis were analyzed,and the expression of p-JAK2,pSTAT1,Bcl-2 and Bax was detected by Western blotting.Results As compared with Sham operation group,renal histological lesion and renal dysfunction were aggravated,level of oxidative stress and apoptosis rate were increased in I/R group,the Bcl-2/Bax ratio was decreased and the expression of pJAK2 and p-STAT1 was up-regulated.As compared with I/R group,AG490 dramatically attenuated histological lesions and oxidative stress,restored the renal function,and reduced the number of apoptotic tubular epithelial cells.AG490 significantly increased the Bcl-2/Bax ratio,and inhibited the expression of p-JAK2 and p-STAT1.Conclusion Blockage of JAK2/STAT1 signaling pathway can alleviate acute kidney injury after liver cold ischemia reperfusion probable through inhibiting the oxidative stress and apoptosis.

Objective To discuss and to compare the curative effects of interventional embolization with different embolic agents in treating giant hepatic cavernous hemangiomas. Methods From 2008 to 2010, a total of 30 cases with clinically proved hepatic cavernous hemangioma were treated with interventional embolization. According to the embolic agents used , the patients were divided into pingyangmycin-lipiodol emulsion mixed with sodium alginate microspheres group(PLE+KMG, group A, n=15) and pingyangmycin-lipiodol emulsion group (PLE, group B, n=15). CT scanning was performed one, 3, 6, 12 months after the treatment to evaluate the curative effect. Results The technical success rate was 100%in both groups. The mean PLE dose used in group A and B was (10.9 ± 5.2) ml and (11.4 ± 4.9) ml respectively, the difference between the two groups was not significant (P > 0.05). CT reexamination performed one, 3, 6 months after the treatment showed that a reduction in tumor volume over 50%in group A was seen in 9, 11 and 14 cases respectively, while in group B it was 0, 3 and 5 cases respectively (P <0.05). One week after the procedure, the degree of pain in patients of group A was more severe than that in patients of group B, the difference between the two groups was statistically significant (P < 0.05). Slight abnormal hepatic function was seen in some patients of both groups, which presented mainly as an elevation of aminotransferase, which returned to normal after symptomatic medication. Follow-up with questionnaire indicted that patients of group A were more satisfied with the treatment than the patients of group B. Conclusion Transhepatic infusion of pingyangmycin-lipiodol emulsion is a safe and effective treatment for giant cavernous hemangioma of the liver. Combination use of pingyangmycin-lipiodol emulsion and sodium alginate microspheres can obviously reduce the tumor size mainly in the first and the third month after the treatment, besides it produces instant clinical effect although the pain is more severe than in patients treated with pure pingyangmycin-lipiodol emulsion.

Objective To observe the effect of capsaicin on lipid deposition in liver cells and the expression of autophagy,to provide new ideas and targets for the study of fatty liver disease.Methods The model of nonalcoholic fatty liver disease (NAFLD) was established by inducing LGF cell line of liver primary cells with oleic acid (40 μg/mL).The experiment was divided into blank control group,oleic acid group,capsaicin group[oleic acid--capsaicin(100 μmol/L)].The level of intracellular lipid was detected by oil red O staining and triglyceride (TG) kit.Western bolt was used to detect the expression level of autophagy marker molecule p62 and LC3,and to calculate the ratio of LC3 Ⅱ/LC3-Ⅰ.Results After treated with 40 μg/mL oleic acid for 24 h,the oil red O staining showed that orange-red lipid droplets were found in the oleic acid group,but there was no obvious orange-red lipid droplet formation in the blank group,which suggesting that the NAFLD cell model was established successfully by using 40 μg/mL oleic acid in vitro.Oil red O staining was observed,the cells in the capsaicin group were significantly less than the oleic acid group,and the content of triglyceride in the liver cells was significantly lower than that in the oleic acid group(P＜0.05).Western bolt test results showed that capsaicin group p62 protein levels were significantly lower compared with the oleic acid group(P＜0.05),while the LC3-Ⅱ/LC3-Ⅰ ratio was higher than that of oleic acid group(P＜0.05).Conclusion NAFLD model was established by inactivating LO2 cell line with oleic acid in vitro.Capsaicin stimulated NAFLD cells,upregulated the autophagy level of NAFLD cells and reduced intracellular lipid deposition,but the specific mechanism need further study.

ObjectiveTo investigate the value of ultrasound in diagnosis and differential diagnosis of uterine arteriovenous fistula (UAF).MethodsUltrasound results of 12 patients with UAF were analyzed retrospectively,and were compared with uterine artery angiography.ResultsUAF showed uneven echo signals of uterine muscle wall near endometrium or cesarean section incision and irregular echo-free zone on ultrasonographies,the typical case of which displayed “honeycomblike” change.Color Doppler ultrasound showed rich blood flow in local area and lake-like or multicolored mosaic change.Spectral Doppler waveform shape was characterized as high-speed low resistance.The ultrasonographic results of UAF were consistent with those of uterine artery angiography.ConclusionUltrasonography combined with uterine artery angiography contributes to the diagnosis of UAF.

Objective To explore the impact of self-care efficacy and psychological resilience on post-traumatic stress disorders (PTSD) in breast cancer patients.Methods 303 patients with breast cancer were investigated with PTSD Checklist-Civilian Version(PCL-C),Chinese version of strategies used by people to promote health (C-SUPPH) and Connor-Davidson Resilience Scale (CD-RISC).Results The total score of PCL-C was (38.02±8.35) and the incidence of PTSD in breast cancer inpatients was 20.13％ with 61 cases.Correlation analysis showed that PTSD was negatively correlated with the score of self-care efficacy (r=-0.387) and psychological resilience (r=-0.341) (P＜ 0.01,P＜ 0.05).Multiple regression analysis showed that self-care efficacy (β=-0.274),psychological resilience (β=-0.149) and neoplasm staging(β=0.136) were influencing factors of PTSD.Conclusion Intervention measures should be taken according to self-care efficacy and psychological resilience of breast cancer patients so as to reduce the PTST incidence and improve mental health of patients.
