In order to improve the traditional teaching method of the experiments,a kind of teaching mode “self-service teaching mode of biochemical experiments” with the character of original and modern thought is created. In turn the virtual instruments and experiments-monitoring system are designed by utilizing the computer technology.

Objective To explore the natural forgetters' episode memory and personality characteristics.Methods Situational Self-Awareness Scale(SSAS),Russell Loneliness Scale and Zimbardo Time Perspective Inventory(ZTPI)are used upon 127 natural forgetters and subjects of control group.in which 90 subjects participate tions,natural forgetters performance worse than subjects of control group(t=1.76 one-tail,P＜0.05),but subjects getters score lower in the SSAS and the future subscale of ZTPI(t1=1.73,P＜0.05 one-tail;t 2=2.70,P＜0.05),and tend to endorse in the present fatalistic subscale of ZTPI(t=2.19,P＜0.05),but don't feel more lonely.Conclusion Natural forgetters episodic memory is selectively micro-injured under the enactment conditions,which is different from the aging impairment mode of selective source memory,and they have some special personality characteristics.

Objective To study the effect of data envelopment analysis evaluation on nursing efficiency in general hospitals.Method The input indexes including the number of enrolled nurse,indirect nursing time,average annual nursing consumables and average annual continuing education time and the output indexes including hospitalized patient number and year-round nursing income of 10 nursing units in our hospital during October 2012 to October 2013 were collected and analyzed with C2R,C2GS2 model and C2R/ C2GS2 ratio from Data Envelopment Analysis.Result About 5 nursing units were effective in terms of overall efficiency,8 ones in terms of unit technical efficiency and 5 one in terms of nursing unite scale efficiency.Conclusions We need improve nursing efficiency in our hospital.Nursing managers should pay attention to the results and improve working process aiming at the practical situations.

Objective To investigate the interrelationship between Golgi phosphoprotein 3 ( GOLPH3 ) expression with vasculoar endothelial growth factor( VEGF) expression in the progression of human gastric cancer by detecting the expression level of GOLPH3 and VEGF. Methods Immunohistochemistry ( IHC) was used to detect the ex-pression of GOLPH3 and VEGF in 55 cases of gastric cancerous and carcinoma-adjacent tissues. Pearson correlation analysis was used to discuss the association between GOLPH3 expression with VEGF expression. Results The im-munohistochemical detection showed that the positive expression rates of GOLPH3 and VEGF were 67. 27%, 58. 18% respectively, which were significantly higher than the positive expression rates in carcinoma-adjacent tis-sues ( P<0. 05 ) . A statistical analysis revealed that the positive expression rate of GOLPH3 and VEGF in the gas-tric cancer tissues were strongly correlated with depth of invasion ( P<0. 05 ) , distant metastasis ( P<0. 01 ) and TNM stages (P<0. 01), whereas it did not significantly correlate with age or gender or size of tumor. Compared with the negative for the GOLPH3 expression, the VEGF expression in gastric cancer tissues positive for the GOL-PH3 expression was significantly higher. The protein level of GOLPH3 expression was positively correlated with VEGF expression (r=0. 508,P<0. 01). Conclusion GOLPH3 overexpression may regulate gastric angiogenesis by upregulating the expression of VEGF, which affects the invasion and metastasis of gastric cancer.

Objective To develop an HPLC method for the simultaneous determination of 7-ethyl-10-hydroxycamptothecin-10-palmitic acid ester(SN38-PA)and its active metabolite 7-ethyl-10-hydroxycamptothecin(SN38)in rat plasma. Methods The inter standard was 10-hydroxycamptothecin. The protein in plasma was precipitated with methanol after acidification with formic acid. SN38-PA and SN38 were separated on Agilent C18 column(4.6 mm×250 mm,5μm) with gradient elution by using the mobile phase of methanol-0.2% formic acid solution. The flow rate was 1 ml/min. The detection wavelength was set at 372 nm. The column temperature was maintained at 30℃. Results The linear ranges for SN38-PA and SN38 were 0.25-62.5(r=0.9998) and 0.05-12.5 μg/ml (r=0.9997) respectively. The limits of quantification were 0.18 and 0.04 μg/ml, respectively. The average relative recovery of SN38-PA and SN38 were 95.89% and 97.03%. The average absolutely recovery of SN38-PA and SN38 were 99.54% and 99.84%. The RSD for intra-day and inter-day were both less than 3%. Conclusion The method is fast, convenient, accurate and sensitive, so it can be used for determination of SN38-PA and SN38 in vivo.

Objectives To study the relationship between TCM syndromes and adiponectin (APN) level, carotid atherosclerosis plaque of hypertension complicated with carotid atherosclerosis, and provide evidence for clinical diagnosis and treatment. Methods One hundred patients of hypertension complicated with carotid atherosclerosis were divided into phlegm syndrome group, stasis syndrome group, and intermingled phlegm and blood stasis syndrome group, and compared with 30 healthy people as control. Carotid atherosclerosis plaque was detected with GE LOGIQ500 color ultrasound system. ELISA was used to determine the serum APN. Results APN of the intermingled phlegm and blood stasis syndrome group was obviously lower than other groups, and there were obvious differences among them. There were more plaques in the intermingled phlegm and blood stasis syndrome group. A negative correlationship was showed between carotid artery intima media thickness (IMT) and APN of hypertension complicated with carotid atherosclerosis. Conclusion There is correlation between TCM syndrome and APN level, carotid atherosclerosis plaque of hypertension complicated with carotid atherosclerosis. The anomalous change of APN and plaque formation of the patients can be preliminarily estimated with the syndrome of TCM.
