ObjectiveTo evaluate the effects of selective cyclooxygenase-2 inhibitor nimesulide lone and combined with cisplatin on tumor growth,and Ki67 and Caspase-3 expression in lung cancer xenografts in nude mice. Methods The mice were randomly divided into 4 groups:the control group,the nimesulide group,the cisplatin group and the nimesulide combined with cisplatin group. A549 cells were injected into BALB/c nude mice subcutaneously.On the 21st day after treatment tumor tissues were collected,and the xenografts growth were observed. The expression of Ki67 and Caspase-3 were detected by immunohistochemical method.ResultsNimesulide combined with cisplatin could significantly inhibited the xenografts growth compared with nimesulide or cisplatin.The tumor inhibition rate was 44.33％ in the nimesulide group,53.61％ in the cisplatin group and 80.41％ in the nimesulide combined with cisplatin group (P ＜ 0.05).Immunohistochemical analysis showed that the expression rates of Caspase-3 was significantly increased in the nimesulide combined with cisplatin group (67.43 ± 23.57 ) ％,the cisplatin group (48.40 ± 20.37 ) ％,and the nimesulide group (38.65 ± 15.37)％,compared with the control group (27.63 ± 13.03)％ (P ＜ 0.05).The expression rate of Caspase-3 was significantly increased in the nimesulide combined with cisplatin group compared with the nimesulide group or the cisplatin group (P ＜ 0.05 ).The expression rate of Ki67 was significantly decreased in the nimesulide group combined with cisplatin group (24.34 ± 15.90)％,the cisplatin group (40.85 ± 22.47)％ and the nimesulide group (53.33 ± 19.67)％ compared with the control group ( 80.43 ± 16.88 ) ％ ( P ＜ 0.05 ).The expression of Ki67 was significantly decreased in the nimesulide combined with cisplatin group compared with the nimesulide group or the cisplatin group ( P ＜ 0.05 ).Conclusion Nimesulide can inhibit human lung cancer A549 cells xenografts in nude mice growth,Nimesulide enhanced the inhibitory effects of cisplatin.The mechanism may be related to inhibition of tumor cell Ki-67 expression,increased expression of Caspase-3,inhibition of tumor cell proliferation,and inducing tumor cell apoptosis.

OBJECTIVE:To investigate the characteristics of adverse drug reactions(ADR)of the hospitals(Level 2 and above) of Wuxi in order to promote rational use of drugs in the clinic.METHODS:2 473 cases of ADR collected from Jan.2005 to Dec.2006 in 11 hospitals(Level 2 and above)of Wuxi were retrospectively studied.RESULTS:Most patients who had ADR were old patients over 60 years and teenagers(≤10years).Most ADR were caused by anti-infection drugs(60.9%),followed by the preparations of Chinese materia medica(13.7%).The intravenous medication was the main route of medication resulting in serious adverse reactions;Most of the ADR cases were known and mild, 74 cases were severe and scarce(3.0%).CONCLU-SION:More attention should be paid to monitoring clinical ADR and the quality of ADR reports needs to be improved.

OBJECTIVE:To evaluate the cost-effectiveness of domestic versus imported acarbose tablets in the treatment of type 2 diabetic mellitus.METHODS:Based on the published medication data for type 2 diabetic mellitus,patients with type 2 diabetic mellitus were assigned to receive domestic acarbose tablets(Group A) or imported acarbose tablets(Group B).The cost-effectiveness of the two groups were compared applying the theory in pharmacoeconomics.RESULTS:Domestic and imported acarbose showed the same effectiveness for type 2 diabetic mellitus,while the costs in the two groups were significantly different.CONCLUSION:As compared with imported acarbose,the domestic acarbose has higher cost-effectiveness ratio.

With the development of laboratory medicine,more and more biomarkers have been discovered and applied in the diagnosis and treatment of acute myocardial infarction.For patients with suspected myocardial infarction,early diagnosis and timely treatment can save endangered myocardium and reduce fatality rate to a great extent.The proper use of biomarkers is of important value in preventing cardiovascular events and improving prognosis.This paper reviews the recent literature on new biomarkers in diagnosis of acute myocardial infarction,introduces the characteristics of these markers and their clinical diagnostic value.

Objective To investigate the relationship between sarcoplasmic reticulum Ca2+modulation proteins and postresuscitation myocardial dysfunction. Methods Thirty-eight SPF male Sprague-Dawley (SD) rats were randomly divided into control group(n=12)and cardiac arrest(CA)group(n=26). CA was induced by intravenous bolus of potassium chloride(40μg/g),and cardiopulmonary resuscitation(CPR)was conducted 8 minutes later. No CA was induced in control group except catheter placement for monitoring cardiopulmonary parameters after anesthesia. Invasive hemodynamic parameters were monitored for 1 hour after CPR. Echocardiogram was performed to evaluate cardiac function. Myocardial samples were harvested 5 minutes and 1 hour after restoration of spontaneous circulation (ROSC),and sarcoplasmic reticulum Ca2+ ATPase (SERCA2a),phosphorylated phospholamban (p-PLB) and rynodine receptor(RyR)were determined by Western Blot. Results ROSC rate of CA group was 92.3%(24/26),and mean recovery time was (68 ±39)seconds. Cardiac function was significantly impaired in CA group at 1 hour after resuscitation, and ejection fraction, fraction shortening (FS), the maximal rate of left ventricular pressure increase/decline (±dp/dt max)were significantly decreased compared with those in control group 〔ejection fraction:0.548±0.060 vs. 0.809±0.043,F=71.692,P=0.000;FS:(34.4±4.4)%vs. (46.0±3.5)%,F=55.443,P=0.000;+dp/dt max(mmHg/s):4 718±743 vs. 7 098±394,P<0.01;-dp/dt max(mmHg/s):-3 824±612 vs.-6 187±473,P<0.01〕. Compared with control group,the expression levels of p-PLB (gray value)was significantly decreased at 5 minutes and 60 minutes(5 minutes:0.64±0.15 vs. 1.29±0.13,P<0.01;60 minutes:0.95±0.08 vs. 1.30±0.09,P<0.05)after resuscitation in CA group,while the level of sarcoplasmic SERCA2a(gray value)and RyR (gray value)showed no significant differences(SERCA2a 5 minutes:1.01±0.18 vs. 1.24±0.07,60 minutes:1.03± 0.14 vs. 1.25 ±0.06;RyR 5 minutes:0.96 ±0.13 vs. 0.97 ±0.13,60 minutes:0.88 ±0.14 vs. 0.99 ±0.11,all P>0.05). Conclusions The impairment of the p-PLB is closely related to postresuscitation myocardial dysfunction.

Recombinant human adenovirus p53(Ad-p53)injection has been used for treating tumors in combination with several local therapeutic methods. Taking liver cancer as an example,this article introduces the combination of Ad-p53 in procedures of interventional therapy. Mechanisms of their effects are emphasized to pursue an optimal synergism in killing tumors. Intratumoral injection is suggested as the first choice of Ad-p53 administration with the least recommended dosage for a single tumor. The optimal time for intervention of liver cancer is supposed to be 2 to 5 days after the administration of Ad-p53. There are several theories on the therapeutic method taking p53 as a target,some of them are contradictional; therefore one has to select either activating or inhibiting the p53 pathway beforehand. For advanced malignancies,the selection should be cautious for appropriater cases from the proper candidates.
