Due to the latent and highly invasive characteristics of liver carcinoma,a majority of patients are frequently not diagnosed until moderate or advanced stage in the disease process,and usually complicate with cirrhosis.Only 15％ -30％ of the patients are eligible for radical resection.The overall survival time is about 3-4 months.Therefore,on the basis of early diagnosis and treatment of liver carcinoma,how to improve the treatment effect of the moderate and advanced liver carcinoma,ameliorate the quality of life and prolong the survival time,becomes the focuses and difficulties both at home and abroad.

Objective:To investigate the relationship between narcissism and entrepreneurial intention and roles of achievement motive and risk aversion in college students.Methods:In this study,375 college students were selected from Henan University.Their narcissism,entrepreneurial intention,achievement motive and risk aversion were assessed with the Narcissism Scale,Entrepreneurial Intentions,The Achievement Motive Scale,and General Risk Aversion Scale.Results:The scores of overt narcissism positively predicted the scores of entrepreneurial intention (3 =0.37,P ＜ 0.001),the predictive effect of covert narcissism on entrepreneurial intention was not significant (β =-0.05,P ＞ 0.05).The scores of achievement motive partly mediated the relationship between the scores of overt narcissism and entrepreneurial intention (95％ CI:0.06-0.22),and this mediation effect was moderated by the scores of risk aversion (β =0.09,P ＜ 0.05).Only when the score of risk aversion was higher (above one standard deviation),achievement motive was a mediator between narcissism and entrepreneurial intention.When the score of risk aversion was lower,the mediate effect was not valid.Therefore,the moderated mediation model was confirmed.Conclusion:It suggest that the moderated mediation model is feasible,that is,achievement motive is a mediator between narcissism and entrepreneurial intention,but this mediation is moderated by risk aversion.

Glucocorticoids are among those most important hormones that maintain the energy metabolic homeostasis within body.The actions of glucocorticoids on target tissues,such as liver and adipose tissue,are not only dependent on circulating glucocorticoid levels but also on glucocorticoid receptor expression.The elevated level of circulating glucocorticoid caused by exogenous or endogenous reasons may contribute to insulin resistance and the other metabolic syndrome such as dyslipidemia,visceral obesity and hypertension.This review summarizes recent advances in the study of glucocorticoid receptor-mediated insulin resistance and its antagonists.

Objective To investigate the relationship between cerebrovascular accident and abnormal electrocardiogram. Methods The ECG abnormalities and clinical data of 314 patients with cerebrovascular accident were analyzed. Results 56.7% patients developed arrhythmia. Among them, the morbility of arrhythmia in patients with cerebral hemorrhage was higher than that of cerebral infarction ( P

7 flavonoids are isolated from the leaves of Hovenia acerba Lindl. On the basis of chemical and spectralmethods (IR,1H,13 CNMR),they are ivdentified as kaempferol(Ⅱ),quercetin(Ⅱ),isoquercetin(Ⅳ),kaempferol-3-Oa-L-rhamnopyranosyl(1)-?-D-galactopyranoside(Ⅶ),kaempferol-3-O-rutinoside(Ⅶ),quercetin-3-O-?-L-rhamnopyranosyl(1→6)-?-D-galactopyanoside(Ⅹ Ⅸ),and rutin(Ⅸ),All of them are isolated for the first time from genus Hovenia.

Magnetic induction method aims at the noninvasive detection of liver iron overload by measuring the hepatic magnetic susceptibility. To solve the difficulty that eddy current effects interfere with the measurement of magnetic susceptibility, we proposed an improved coil system based on the static field magnetization principle in this study. We used a direct current excitation to eliminate the eddy current effect, and a rotary receiver coil to get the induced voltage. The magnetic field for a cylindrical object due to the magnetization effect was calculated and the relative change of maximum induced voltage was derived. The correlation between magnetic susceptibility of object and maximum magnetic flux, maximum induced voltage and relative change of maximum induced voltage of the receiver coil were obtained by simulation experiments, and the results were compared with those of the theory calculation. The contrast shows that the simulation results fit the theory results well, which proves our method can eliminate the eddy current effect effectively.

Objective To strengthen the management of contaminated area of sterilization and supply center, increase the cleaning quality of instruments and control nosocomial infection. Methods We executed the following measures: paying attention to the decontamination work, changing concepts, refining regulations, establishing programmed decontamination process, specification of work, thinning pest responsibility, strengthening infection mangement of contaminated area, effect examination and training and checking. Results The bacteria removing rate reached 95.3%. Conclusions Refining management could result in perfect cleaning effect which was applicable in the management of contaminated area of sterilization and supply center.

Objective To construct the specific small hairpin RNA(shRNA)plasmids for Formin-like 2(FMNL2)gene,and to observe its effect on proliferation of SW620.Methods Plasmids FMNL21 shRNA and plasmids FMNL22 shRNA complimentary to the sequence responsible for the function domain of human FMNL2 were constructed and transfected into SW620,respectively.The inhibition rates of FMNL2 expression were detected by re-al-time PCR after transfection with PGenesil-FMNL21 and PGenesil-FMNL22,respectively.The expression of FMNL2 was detected by real-time PCR at 12,24,48,72 and 96h after transfection.At 48 h and 72 h after transfection,the proliferation of SW620 was detected using MTT assay.Resuits The transfection rate in SW620 was(60.8±2.8)%for PGenesil-FMNL21,(58.7±2.9)%for PGenesil-FMNL22,and(62.6±1.7)%for PGenesil-HK(P＞0.05).The inhibition rate of FMNL2 expression after transfection with PGenesil-FMNL21 was 77.1%,which was the highest.The inhibition rates of FMNL2 expression were 13.5%,57.3%,80.3%,62.4%,and 33.2%at 12,24,48,72and 96h after transfection respectively.The proliferat capability of SW620 was obviously lower than that of control cells(P＜0.05).Conclusion Both plasmids FMNL21 shRNA and plasmids FMNL22 shRNA can inhibit the expression of FMNL2,of which Pgenesil-FMNL21 execs the greatest role.FMNL2 could be related to the proliferation of SW620.
