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.

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.

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

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.

To sacrifice the function of the sphincter of Oddi in the routine management of iatrogenic biliary injury,e.g. by using cholangio-enterostomies, is often complicated by ascending biliary infection, cholangitis and an increased risk of cholangiocarcinoma. It is necessary to find a material which can protect the bile duct. As reported, biodegradable materials which are hopeful to be used clinically have the advantages of being non-immunogenic, gives temporary supportive function, and produces harmless degradation products. This article aims to review the advances in researches on biodegradable materials for bile duct repair.

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.
