Objective To investigate the status of fatigue and depression and their influencing factors in patients with acute coronary syndrome, and analyse the correlation of fatigue, depression and self-management behavior. Methods 113 patients were investigated by using Fatigue Symptom Inventory (FSI), Patient Health Questionnaire-9 (PHQ-9), Coronary artery disease Self-management Scale (CSMS). Results The score of fatigue was (4.59±1.93)points, while depression scored (5.05±1.48)points and self-management behavior scored (57.29 ±8.29)points; the score of fatigue, depression of female patients were higher than that of male patients, which had statistical difference(t=2.535-5.894, P<0.05);Regression analysis showed that gender, time of illness, number of other chronic diseases were major factors affecting fatigue while gender and treatment method were major factors affecting depression; there were negative ralationships between self-management and fatigue, self-management and depression (r=-0.855-0.682). Conclusions Fatigue, depression are common in patients with acute coronary syndrome, and can affect their self-management behavior, and the female patients are more susceptible to fatigue and depression.

Objective To determine the relationship between cigarette smoking and the incidence of systemic lupus erythematosus.Methods Database including Cochrane Library,Pubmed,OVID and Elsevier were electronically searched to collect case-control and cohort studies on the relationship between cigarette smoking and incidence of systemic lupus erythematosus.The literatures were screened and the data were extracted independently according to the inclusion and exclusion criteria.The quantitative analysis were performed by using Stata 12.0 software.Results The pooled OR values (95％ confidence interval)of current smoking and ever smoking were 1.82 (95％CI 1.42～2.34) and 1.22 (95％CI 0.96～1.56) respectively.Conclusions Our Meta-analysis revealed a moderate but statistically significant association between current smoking and development of systemic lupus erythematosus.However,it is still not confirmed whether the past smoking is one of the risk factors of systemic lupus erythematosus.

OBJECTIVE:To prepare folic acid(FA)-loaded vincristine(VCR)nano liposome(VCR-nLip-FA)and to study its effects on human liver and lung cancer cells. METHODS:VCR-nLip-FA was prepared by ammonium sulfate gradient method,and particle size,Zeta-potential,encapsulation rate and release rate were investigated. Taking human liver cancer HepG2 cells and lung cancer A549 cells as example,uptake rate and inhibitory effect in vitro (5-80 μg/ml) were compared between VCR-nLip-FA and VCR-nLip. RESULTS:The particle size distribution,average particle size,average Zeta-potential,average encapsulation rate and 24 h accumulative release rate of VCR-nLip-FA were 98.1-159.0 nm,132.2 nm,-40.1 mV,(86.6±3.5)%(n=4)and(42.2± 2.6)%. Compared with VCR-nLip,there was no statistical significance in uptake rate of A549 cells to VCR-nLip-FA and inhibitory effect of VCR-nLip-FA on A549 cell viability (P>0.05);uptake rate of HepG2 cells to VCR-nLip-FA and inhibitory effect of VCR-nLip-FA on HepG2 cell viability increased significantly (P<0.01),in dose-dependent manner. CONCLUSIONS:Prepared VCR-nLip-FA can target anti-tumor drug to HepG2 cells efficiently,and highly inhibit the growth of HepG2 cells. But it has no higher effects on A549 cells.

Objective To investigate the characteristic of intelligence of children with attention deficit hyperactivity disorder (ADHD).Methods 60 ADHD children were estimated with Wechsler Intelligence Scale for Children-fourth edition (WISC-Ⅳ). Results The full scale intelligence quotient (FSIQ) and 4 indices of ADHD children were lower than the average (P<0.05). All the subtests scores of ADHD children were lower than the average (P<0.05) except decoding. Conclusion The general intelligence and abilities of verbal comprehension, reasoning,working memory and operation speed are in the normal range in ADHD children, but poorer than normal children.

Objective To evaluate the inhibitory activity of Herba Taraxaci extract on Escherichia coli DH5α (E. coli DH5α) and to investigate proteomic response of E. coli. Methods Medicinal powder of Herba Taraxaci was extracted with the solvents of different polarity ( n-hexane, ethyl acetate, distilled water) , and then the obtained 8 different extracts were subjected to thin layer chromatography ( TLC) analysis. Microdilution method was performed to detect the minimum inhibitory concentration ( MIC) of different extracts and the growth curves were described. The protein expression profiles of E . coli treated with the extracts were analyzed by sodium dodecyl sulfate polyacrylamide gel electropheresis ( SDS-PAGE) and two dimensional electrophoresis (2-DE) . Results Water decoction of Herba Taraxaci could obviously suppress the growth of E. coli with a MIC of 1.95 mg/mL. The different extractions exhibited no antibacterial activity except ethyl acetate phase 3 with a MIC of 0.13 mg/mL, which was equal to 19.23 mg/mL of crude drugs. The results of TLC analysis showed that chlorogenic acid was undetectable in n-hexane extract and ethyl acetate phase 1 extract, and ethyl acetate phase 2 and 3 extracts showed obviously increased spots. The results of SDS-PAGE and 2-DE showed that water decoction of Herba Taraxaci had inhibitory effect on the expression of functional protein. The results of 2-DE showed that after treatment with ethyl acetate phase 3 at the concentration of 2 × MIC for 21 hours, the amount of protein spots were 92 less than those of the blank control group, the spots of E. coli DH5α soluble protein with expression amount down-regulated doubly were 24, and those with expression amount up-regulated doubly were 19. Ethyl acetate phase 3 extract had an effect on down-regulating the protein expression of E. coli DH5α soluble protein pH3-10, and water decoction of Herba Taraxaci had inhibitory effect on E. coli DH5αprotein expression. Conclusion Herba Taraxaci has significant antibacterial activity on E. coli DH5α, and the water-soluble fraction of chlorogenic acid and caffeic acid might be the active components. The possible antibacterial mechanism may be related with the regulation of bacterial protein expression.
