Targeted agents for advanced colorectal cancer mainly include inhibitors of vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR).Studies show that bevacizumab and cetuximab can improve the prognosis of advanced colorectal cancer patients,but there is slight difference in the choice of chemotherapy regimens when combined with them.Bevacizumab and cetuximab can improve the overall survival of K-ras wild-type colorectal cancer patients similarly.The emergence of new targeted drugs such as aflibercept,regorafenib provides more choices for the targeted therapy of advanced colorectal cancer patients.

Objective To analyze the variations and influencing factors of hospitalization expenditure of cervical cancer patients among urban employees in Beijing from 2006 to 2010,and to provide evidences for developing reasonable measures of medical expenses control.Methods Based on the hospitalization expenditure data of 1146 cervical cancer cases,the paper probed into the changes of hospitalization age and hospitalization expenditure,and the influencing factors of hospitalization expenditure by means of descriptive analysis and multiple stepwise regression.Results The last 5 years witnessed no significant change in the first hospitalization age of cervical cancer patients,rise of hospitalization age,gradual rise of the hospitalization expenditure per time along with their age groups,as well as a rising trend of the average hospitalization expenses,average drug cost and proportion of average drug cost year by year.Results of the multiple stepwise linear regression showed that days of stay,proportion of drug cost and surgery or not as important influencing factors for hospitalization expenditure.Conclusion Hospitalization expenditure of cervical cancer keeps growing.Against this background,reasonable shortening of the days of stay,reasonable setup of an appropriate proportion of out-of-pocket payment,and reduction of the proportion of drug costs become effective means to reduce hospitalization expenditure.

In order to create a high-quality online course of Medical Ethics, this research group retrieved 16 domestic MOOC platforms in order to understand the current status of the online course construction of Medical Ethicsin Chinese universities before the outbreak of epidemic. The survey results showed that 12 teaching teams from 11 universities have built the Medical EthicsMOOC on 8 network platforms. These 12 online courses have not only played an important role in the teaching of this course during the epidemic, but also would provide valuable experience for leading Chinese universities in the online learning and teaching reform of Medical Ethics. Finally, there are three suggestions for the current problems about online teaching of medical education: firstly, increase network speed and reduce network traffic charges; secondly, utilize virtual space to make up for the lack of real space; thirdly, set up cross-professional, interdisciplinary and trans-school's compound golden courses teaching teams.

It's a new financial management system that our country implemented the management of separating the income and expenditure in the community health services.Beijing is one of the former pilot cities which carried on the management of separating the income and expenditure.To know the effectiveness of the implementations and its influence to the health services,this article analyses the status of community health services,the financial investment and the performance results in Beijing.Considering the above,this paper also provides policy recommendations on the development of health services in Beijing to improve the new urban medical service system which based on the community health services.

Objective To investigate the relations between BNP and cTnI leveh in patients with CHF and cardiac function.Methods 75 patients with CHF were selected as observation group and another 30 healthy people were selected as control group.BNP and cTnI levels were detected by electrochemiluminescence immunoassay and the data were analyzed.Results BNP and cTnI of observation group were significantly higher than control group,the difference was statistically significant(t=3.897,4.127,all P＜0.05);comparison of BNP and cTnI levels in different classification of cardiac function of observation group had significant difference(F=4.765,5.876,allP＜0.05);Linear corrlation analysis showed that:BNP and cTnI both positively correlated to classification of cardiac function(r=0.853,0.647,all P＜0.05),BNP and cTnI increased significantly with the increase of cardiac function classification.Conclusion BNP and cTnI increased significantly in patients with CHF and closely related with cardiac function.they were ideal index to evaluate the CHF severity and had a good clinical value to judge the status and function of heart in patients with CHF.

Objective To study the effect of the Hushengujingfang (HSGJF), a traditional Chinese prescription, on the biological behaviour of rat mesangial cell (MC). Methods MC was cultured in vitro, and the serologic pharmacology method was employed. The cells were divided into serum groups of HSGJF, LPS group and control group. Added the different concentration actors to MC and cocultured then made into unicell suspension. After examining it by flow cytometry, the percentage of G 0 /G 1 period, S period, G 2 /M period in cell cycle and the inhibition percentage of S period and cell proliferation index were calculated. Result The actors of different concentration had different effects to the multiplication cycle of MC and delayed the entry of cell cycle at G 0 /G 1 period. HSGJF induced apoptosis of MC. Conclusion One of action mechanism of HSGJF treating mesangial proliferative nephritis and other renal glomerular diseases is to inhibit MC proliferation and promote apoptosis.

Objective: To investigate the alteration of red cell deformability (RCD) and adenosine triphosphatase (ATPase) activity of cell membrane in essential hypertensive (EH) patients and essential hypertension patients complicated with cerebral infarction (HCI). Methods: Twenty healthy individuals, 30 EH patients and 30 HCI patients were selected as subjects. The erythrocyte deformability indexes (DI)、 Na+, K+-ATPase and Ca2+ATPase activities were examined. Results: (1) EH patients had significantly higher DI, lower ATPase activity as compared to healthy individuals. There were significantly negative correlation between DI and ATPase activity, and a significantly positive correalation between DI and diastolic blood pressure in EH patients; (2) There was significantly higher DI, lower ATPase activity in HCI patients than those in EH patients. There was significantly negative correlation between DIand ATPase activity in HCI patients. Conclusion: (1) RCD decreases in EH patients, and RCD is correlated to the decreased ATPase of cell membrane and elevated blood pressure; (2) The decreased RCD level may be related to the occurrence of HCI.

Objective To investigate the mechanisms of angiotensinⅡ receptor blockade in protection against kidney lesion in hypertensive rats.Methods The investigation was comprised with normotensive control (WKY) and hypertensive group (SHR) which included treated and untreated group. Relevant index such as blood pressure and ultrastructural changes in glomerulus with transmission electronic microscope were acquired in three-month old and eight-month old. Losartan was administrated with 20mg?Kg -1 ?d -1 in treated group.Results The volume density of vessel endothelium, mesangial cells and mesangial area of SHR was significantly larger than that of WKY(P

Objective To observe the influence of serum containing Tongmai on the anoxic myocardial cell. Methods The serum containing Tongmai effective components was extracted and used to interfere the anoxic myocardial cell, then the concentration of the LDH and troponin I in the culture medium of the cardiac myocyte was measured. Results The concentration of LDH and troponin I increased significantly in the culture mediun of the anoxic cardiac myocyte. The intervention of the serum containing Tongmai can significantly decreased the concentration of LDH and troponin I in the culture medium of the anoxic cardiac myocyte. Conclusion Tongmai can protect the cardiac myocyte from anoxic damage.

RESULTS: On mice fed on Rhubarb root, Jianpixiaoshi i Pill can effectively potentiate immunity, improve the velocity of stomach and intestine, expedite the advance speed of ink in the small intestine and the velo city of gastric emptying, reduce the residual rate of methyl orange in stomach. On rats fed on lard and cabbage, J ianpixiaoshi Pill can gain mouse's weight improved, increase the total acidity of the gastric juice and the activity of pepsin. CONCLUSION: Jiah pixiaoship Pill has remarkable effect on improvin g the function of intestine and stomach.
