ObjectiveTo explore the effect of statin in reduction of my ocardial injury in patients undergoing percutaneous coronary intervention(PCI).MethodsTotal of 185 patients undergoing PCI were included,140 patients were received atorvastatin before PCI,while 145 were not given statins at the time of PCI.Creatine kinase-MB and troponin Ⅰ were measured at baseline and at 8 and 24 hours after the procedure.ResultsPost procedurul peak levels of troponin Ⅰ and creatine kinase-MB were(0.12 ±0.26) μg/L and(2.61 ± 3.07) μg/L in the observation group,which were significantly lower than(0.51 ± 1.14) μg/L and( 6.85 ± 14.38 ) μg/L in the control group( t =3.951,3.414,P ＜ 0.05).ConclusionPretreatment with atorvastatin for 7 days could significantly reduces procedural myocardial injury in elective PCI.

Objective:To study the reversal effect of tamoxifen(TAM)on the expression of mdr1 in human pancreatic cancer cell lines.Methods:The inhibtion effect of TAM on pancreatic cancer cell line SW1999、Capan-Ⅱ and mammary cancer cell line T47D were studied;The influence of TAM on mdr1 protein/mRNA expression in SW1999、Capan-Ⅱ and T47D were studied using the method of flow cytometer and RT-PCR.Results:The high dose TAM could inhibit Capan-Ⅱ cell line.TAM could reverse the expression of mdr1 protein and mRNA in Capan-Ⅱ cell line and T47D cell line. Conclusion:The high dose TAM could inhibit Capan-Ⅱ cell line,maybe related with reduction of the expression of mdr1 protein and mRNA.

Objective To present the development of the Naming test tool ( Huashan Naming Test, HNT)for Chinese cultural and by amnestic mild cognitive impairment ( aMCI ) and mild Alzheimer' s disease (AD) between the detection of memory decline,and to analyze the validity of its trial.Methods 100 normal elders from communities in Shanghai, 100 patients with amnestic mild cognitive impairment (aMCI), and 95 patients with mild Alzheimer's disease (AD) who received an education of junior high school or above and were evaluated by neuropsychological tests including mini mental state examination ( MMSE), auditory verbal memory test, Huashan Naming tests etc.8 cognitive tests.The groups of MCI and AD patients finished cranial MRI.100 items with HNT including 20 animals,10 vegetables,10 fruits ,20 tools ,20 household , 10 vehicles, 10 stationery.Results 1.HNT items to determine: 22 items were excluded due to the completion of the three groups were not significantly different; 8 items were excluded due to the completion of the normal elderly group was lower than 75%; 10 items were excluded from the analysis of variance Fvalue of the minimum value.The remaining 60 items,according to the size of the arrangement and completion rates were divided into two versions of odd and even, respectively HNT-Ⅰ and HNT-Ⅱ.2.HNT characteristics:in normal elderly group age, sex were found to had no significant factors affecting overall scores of HNT-Ⅰ and HNT-Ⅱ but level of education, MMSE score was significantly correlated (P ＜0.05).As cut-off score ≤ 26 for spontaneous naming of HNT,the sensitivities of HNT-Ⅰ for aMCI ,mild AD were 44%, 84% respectively, specificities were all around 84%; the sensitivities of HNT-Ⅱ for aMCI , mild AD were 56% ,83% respectively,specificities were all around 80%.Conclusion HNT is a Chinese cultural background,time-consuming short and good name validity test,and it is worth further promoting the application.

OBJECTIVE:To explore the standardized package of Metformin tablets to meet clinical needs. METHODS:Statis-tics was conducted for the utilization data of Metformin tablets in medical and health institutions from 6 cities of China;question-naires were designed to investigate and analyze the evaluation for the suitability of physicians,pharmacists and patients in the pre-scription,deployment and use links to Metformin tablets with different packaging loaded amount in Beijing and Haikou. RE-SULTS:For 0.5 g/tablet,the daily dose of 1.5 g accounted for the largest proportion (32.23%-69.91%) in 5 cities except for Chengdu. Totally 490 questionnaires about package suitability of Metformin tablets in outpatient department were sent out,includ-ing 478 valid questionnaires with effective rate of 97.5%. Results showed that packaging quantity with 4 weeks was considered as appropriate by physicians,pharmacists and patients in Beijing;however,packaging quantity with 1-2 week(s) was considered as appropriate by physicians,pharmacists and patients in Haikou;300-500 tablets of packaging quantity were preferred to be appropri-ate with the matching degree of automatic dispensing machines in both places. CONCLUSIONS:Considering the results in 2 plac-es,for 0.5 g/tablet,2 weeks is appropriate for the packaging loaded amount in outpatient department,that is 0.5 g×45 tablets/box;and 300-500 tablets/box is appropriate for inpatient pharmacies.

ObjectiveTo study the anti-cancer effects and mechanism of Gexia-Zhuyu decoction combined with cyclophosphamide on EAC liver cancer mice.MethodsChoose EAC liver cancer mice cell lines and production of animal models of tumor.The mice were completely randomized into blank group,model group,the Chinese medicine group,CTX group,Chinese medicine and CTX group.The blank group and model group were given normal saline 0.4 ml/d; traditional Chinese medicine group was administrated with Gexia-Zhuyu decoction (11 g/kg body weight ) 0.4 ml/d gavage; CTX group was given intraperitoneal injection of 2 mg/ml of cyclophosphamide 0.4 ml/d; and traditional Chinese medicine and CTX group was given Gexia Zhuyu decoction 0.4 ml/d orally and CTX intraperitoneal injection of 0.4 ml/d.Ten days after the administration,the body weight of mice and the general condition were tested,and morphology was observed under the light microscope electron microscope mesenchymal tumor angiogenesis situation.Results Gexia-Zhuyu decoction combined with cyclophosphamide in mice could improve appetite,gain weight,and greatly reduce the tumor stroma in the number of capillaries under the electron microscope together with significant pathological morphological changes.Conclusion Gexia-Zhuyu decoction combined with cyclophosphamide had anti-cancer effects which can improve the quality of life and inhibit the growth of tumor in interstitial capillaries.

Objective To investigate the anti carcinoma role of integrin targeted photodynamic therapy (PDT) on pancreatic carcinoma cells in vitro.Methods Pancreatic carcinoma cells SW1990 were divided into four groups:cells without quantum dots (QDs) and light-treated as blank control group,pure light-treated group,photosensitizer group and PDT group.The targeting of QDs-arginine,glycine,aspartic acid (RGD) and integrin probe was confirmed by laser confocal microscopy.And as a photosensitizer for photodynamic therapy,after treated for 48 hours the morphology changes of pancreatic carcinoma cells of each group were observed.After 48 hours,the cell proliferation,apoptosis and cell cycle changes were detected by methyl thiazolyl tetrazolium (MTT) assay and flow cytometry (FCM).The expressions of myeloid cell leukemia-1 (Mcl-1),protein kinase B(Akt) and tumor necrosis factor-related apoptosis inducing ligand (TRAIL) were detected by reverse transcriptase polymerase chain reaction(RT-PCR).The amount of reactive oxygen species (ROS) of each group were evaluated by fluorescence probe.One-way ANOVA was performed for comparison between groups to analyze the treatment effects of PDT group.Results The QDs RGD probe could effectively targeting pancreatic carcinoma cells.The MTT results indicated that the relative inhibition rate of pancreatic carcinoma cells proliferation of PDT group was statistically higher than that of the other groups at 24,48,72 h (F=73.00,85.10,126.58; all P＜0.01).The FCM results revealed that the cell apoptosis rate of PDT group (17.860％ ±1.230％) was higher than that of the other groups (F=130.617,P＜0.01) and cell cycle G0/G1 phase (69.14％±2.63％) and S phase (24.41％ ± 2.67 ％) retardance was also significant (all P＜0.05).The expression of proliferation and apoptosis related gene Mcl-1 and Akt at mRNA level was lower than that of the other groups however the expression of apoptosis-inducing ligand TRAIL at mRNA level was higher than that of the other groups (F=567.456,446.817,145.238; all P＜0.05).The ROS level of PDT group was higher than that of the other groups (F=3262.559,P＜0.01).Conclusion PDT with a QDs-RGD probe could significantly inhibit pancreatic carcinoma cell proliferation and promote cell apoptosis.
