Objective To investigate the effect of lentinan injection in different treatment administration of oxaliplatin combined with capecitabine in treatment of gastric cancer and the effect on the peripheral blood of patients with CEA and CA199 levels.Methods 90 cases in our hospital from September 2009 to September 2012 were selected as research subjects, according to patients with lentinan injection treatment, the patients were divided into A, B and C three groups, the effect and the adverse effects of chemotherapy in three groups of patients, detection of serum CEA and CA-199 levels. Results CR, PR, SD and PD of A groups were 12, 7, 8, 3 cases, RR was 63.3%, obviously higher than that of B, C two groups, the difference was statistically significant (P<0.05), group A patients with leukopenia I,II and III degree were 15, 10, 5 cases of gastrointestinal reaction, I, II, III were 12, 10, 8 cases of abnormal liver function, I, II and III degree were 14, 9, 7 cases.A group, leukopenia, gastrointestinal tract, liver function abnormal lesion was lower than the B group and C group, the difference was statistically significant (P<0.05), CEA, CA199 level before treatment compared to no difference, one course of chemotherapy, after two courses of A, B, C three groups of patients with CEA and CA199 level were before treatment decreased, and the level of group A was significantly lower than that of B, C two B, C group, no significant difference between the two groups. Conclusion Lentinan injection helps to improve the sensitivity of chemotherapy in patients with gastric cancer, reduce adverse drug reactions, reduce the level of tumor markers, improve the prognosis of patients with gastric cancer.

Objective To investigate the influence of risperidone on differentiation of 3T3‐L1 pre‐adipocytes .Methods 3T3‐L1 pre‐adipocytes were induced to differentiate into mature adipocytes by adopting the classic hormone cocktail method and observed by the oil red O staining .Meanwhile ,the inducing medium was added with risperidone for studying its influence on 3T3‐L1 pre‐adi‐pocytes differentiation .Results 3T3‐L1 pre‐adipocytes were successfully differentiated into the mature adipocytes ,0 .1 ,1 ,10μmol/L risperidone all could inhibit the differentiation of 3T3‐L1 pre‐adipocytes .Conclusion Risperidone can inhibit the differentiation of 3T3‐L1 pre‐adipocytes .

OBJECTIVE:To bring the computer network into full play in effectively monitoring therapeutic recipe for patients to realize individualized administration of drugs.METHODS:According to the phasic characteristics of forming recipe, a local network model for monitoring therapeutic recipe has been set up.RESULTS & CONCLUSION:By computer and local network monitoring, the quality of prescription can be improved and individualized administration of drugs will further be achieved.

Objective To investigate the effect of positive acceleration (+Gz) on monophasic action potential duration of 90%repolarization( MAPD90 ) and transmural dispersion of repolarization ( TDR) in ventricles of rabbits and to explore the cellular electrophysiologic mechanism of tachyarrhythmia induced by positive acceleration .Methods Twenty-four healthy, male New Zealand white rabbits were randomly and equally divided into control group and +Gz group.The +Gz group rabbits were given +8 Gz exposure, 1 min a time, 3 times a day,and a total of 7 days.The two groups were subjec-ted to Holter monitoring at the same time to observe the incidence of tachyarrhythmia .Using the monophasic action potential ( MAP) recording technology , the MAP of the left ventricle was recorded while MAPD 90 and TDR were measured .By using Burst stimulation method , the right ventricular anterior wall of the rabbits was stimulated , and the incidence of tachya-rrhythmia was observed .Results The Holter record showed that the incidence of tachyarrhythmias in +Gz group was 55%(6/11), but the control group did not have any case of tachyarrhythmias .Compared with the control group ,MAPD90 of en-docardial and epicardial cells was significantly decreased in the +Gz group, while MAPD90 of middle myocardial cells did not change significantly ,but TDR was increased obviously .Four rabbits in +Gz group suffered from tachyarrhythmias dur-ing Burst stimulation ,and the incidence of tachyarrhythmias was 40% ( 4/10 ) .Conclusion +Gz exposure can increase the incidence of tachyarrhythmias .The shortened MAPD90 of ventricular muscle cells and the increased TDR may be the cell electrophysiological mechanisms of tachyarrhythmias induced by +Gz.

Objective:To observe the protective effect of deproteinized extract of calf blood (DECB)on the ethanol-induced liver injury of the mice,and to preliminaryly discuss its mechanism. Methods:Sixty healthy ICR mice were divided into control group,model group,positive drug group,low,medium and high doses of DECB groups (n=10).By intragastric administration,the mice in control group were given 20 mL·kg-1 saline solution, the mice in low,medium and high doses of DECB groups were administrated with 0.125,0.250,0.500 g·kg -1 DECB,and the mice in positive drug group were administrated with 0.63 g·kg -1 Hugan Tablets;once a day for 30 d. 1 h after the last administration,except control group,the mice in other groups were administrated with one-time grant of 50% ethanol 14 mL·kg -1 ,and fasted for 16 h to establish the models of acute alcohol liver injury.The endurance alcohol time and drunk time of the mice were determined,the activities of aspartate aminotransferase (ALT)and alanine transaminase (AST)activity in serum of the mice were detected,the levels of triglyceride (TG),glutathione (GSH)and malonic dialdehyde (MDA)in liver tissue were determined,and the pathological changes of liver tissue were detected.Results:Compared with model group,the drunk symptoms of the mice in different doses of DECB groups were obviously reduced,the endurance time of the mice in high dose of DECB group and positive drug group was prolonged (P <0.05),and the drinking time was shortened (P <0.05);the ALT and AST activities in serum in mediun and high doses of DECB groups were significantly lower than those in model group (P <0.05).Compared with model group,the MDA and TG levels in liver tissue of the mice in medium and high doses of DECB groups and positive drug group were obviously reduced,and the GSH levels were increased (P <0.05);compared with model group,the pathological damages of liver tissue of the mice in high dose of DECB group caused by ethanol were significantly reduced.Conclusion:DECB can improve ethanol-induced liver injury which may be related to the inhibition of hepatic oxidative stress response.

Objective To investigate the incidence of diseases in member of rescue teams in the Wenchuan earthquake in Sichuan Province.Method Twenty days afer the Wenchuan earthquake in 2008,5 068 resucing staff of rescue learns as random and cluster sample were investigated and analyzed to find the factors impacting their fitness associated with their characters,diseases,work,and encampment styles.Results Members of rescue teams suffered from the following diseases:insect dermatitis (18.37%),tinea pedis (10.83%),acute upper respiratory infection (10.56%)and solar dermatitis (6.20%).Contrasted by work tasks,staff resucing on the front line had the highest incidence of acute upper-respiratory infection(11.04%) ,logistics workers had the highest incidence of tinea pedis(15.21% ),and more patients of acute gastroenteritis,insect dermatitis,gingivitis emerged from medical personnel group(P<0.05).The encampment sites were devided into three sorts:plain land,hillside and valley.The staff stayed at valley had higher incidence of acute upper respiratory infection (24.90%),insect dermatitis (36.50%) and tinca pedis (20.02%)than those worked at plain land and hillside (P<0.01).The incidence of acute gastroerrteritis(1.26%) ha staff resides hillside is lower than that in valley or plain land (P<0.05).Conclusions In the period of rescue actions in the guake-hit region,the members of rescue teams suffered from famihar diseases such as dermatitis and acute upper-respiratory infection,etc.The incidence of diseases is associated with their work tasks and the topography of cantonment.
