Objective To evaluate the effect of homemade tirofiban in percutaneous coronary intervention for acute myocardial infarction. Methods Sixty four cases of consecutive acute myocardial infarction were enrolled and divided into two groups: the tirofiban group (n=34) and the control group (n=30). In addition to intravenous heparin, patients in the tirofiban group received a bolus dose of tirofiban (10 ?g/kg) before stenting and followed by a 0.15 ?g/(kg?min) infusion for up to 12-36 hours. The control group only receive routine intravenous heparin therapy before and during PCI. The post operation TIMI blood flow, bleeding events and major adverse cardiac events were observed in the 2 groups. Results A 97.1% of patients in the tirofiban group compared with 76.7% in the control group obtained TIMI grade 2-3 flow respectively. Among them, 91.2% in the tirofiban group but 70.0% in the control obtained TIMI 3 flow. There were no serious in-hospital bleeding complications and MACE. Conclusion Homemade tirofiban is effective in improving the TIMI grade and prognosis of acute myocardial infarction after PCI.

Objective To study the effects of miR-200b on proliferation and migration of sw620 colon cancer cells,and its regulation effect on E-cadherin expression.Methods The expressions of miR-200b in sw620 cells at 24 h and 72 h after pEGP-miR-200b transfection were detected by real-time PCR (RT-PCR).The change of the expression level of E-cadherin after miR-200b transfection was detected using the methods of RT-PCR and Western blot.The proliferation and migration abilities were measured by MTT and scratch test after miR-200b transfection.Results The expressions of miR-200b in sw620 cells at 24 h and 72 h after pEGP-miR-200b transfection raised significantly compared to the control group (t =11.579,P ＜ 0.01 ; t =11.579,P ＜0.01).MiR-200b transfection inhibited the proliferation abilities of sw620 cells.It is the most significant of the inhibitory effect on the third day and the inhibition rate was 55.34％.MiR-200b transfection markedly inhibited the migration abilities of sw620 cells.The two groups had significant difference in the migration distance of 24,48,72 h (t =11.579,P ＜0.01 ; t =10.419,P ＜0.01 ; t =6.955,P ＜0.01).The mRNA and protein expressions of E-cadherin gene increased significantly by transfecting miR-200b gene in sw620 cells (t =10.432,P ＜ 0.01 ; t =8.325,P ＜ 0.O1).Conclusion Up-regulated expression of miR-200b could inhibite the proliferation and migration abilities of sw620 colon cancer cells.The involved molecular mechanism is probably related to the change of E-cadherin expression.

BACKGROUND:Stem cels from the apical papila are a new kind of mesenchymal stem cels, and whether it can
be used in root regeneration is the key to the present study. OBJECTIVE:To culture rat stem cels from the apical papila and periodontal ligament stem celsin vitro, and to compare the biology behaviors of these two kinds of cels, thereby providing experimental basis for the application of stem cels from the apical papila in root regeneration. METHODS:The apical papila, as wel as the periodontal ligament tissues from the healthy mandibular teeth of young rats were digested and cultured. Immunophenotypes of stem cels from the apical papila and periodontal ligament stem cels were detected by immunofluorescence technique. Then, cel growth curves were determined by MTT method and mineralized nodule formation was observed by alizarin red staining. RESULTS AND CONCLUSION:Stem cels from the apical papila and periodontal ligament stem cels were both positive for STRO-1. Stem cels from the apical papila were positive for CD90 and weakly positive for CD146. Periodontal ligament stem cels were positive for CD146 and weakly positive for CD90. The absorbance values of stem cels from the apical papila and periodontal ligament stem cels increased with the increasing of time and became stable at 8 days. Since the 4th day, the proliferation capacity of stem cels from the apical papila was significantly stronger than that of periodontal ligament stem cels (P < 0.05). Both of stem cels are visible to have mineralized nodule formation. Compared with the periodontal ligament stem cels, stem cels from the apical papila were stained obviously deeper and had more mineralized nodules. These results show that stem cels from the apical papila have stronger proliferation capacity and mineralization ability than periodontal ligament stem cels.

BACKGROUND:Mesenchymal stem cels can secrete a variety of cytokines and growth factors that promote the survival of surrounding cels and play a paracrine role. OBJECTIVE:To investigate the effect of human umbilical cord mesenchymal stem cels on the proliferation and apoptosis of ectopic endometrial cels. METHODS:After isolation and culture, human umbilical cord mesenchymal stem cels and ectopic endometrial cels were co-cultured as observation group, and ectopic endometrial cels cultured alone served as control group. At 24, 48, 72 hours of culture, the proliferation and apoptosis of ectopic endometrial cels were detected by MTT and flow cytometry, respectively; RT-PCR was used to measure the expression ofPTEN gene in ectopic endometrial cels. RESULTS AND CONCLUSION:At 24, 48 and 72 hours, the proliferation of ectopic endometrial cels in the observation was inhibited significantly as compared with the control group, and the hypodiploid peak ratio also increased significantly (P < 0.05). Over time, the cel inhibition rate was gradualy declined, and there were significant differences at different time points (alP < 0.05). Compared with the control group, the expression of PTEN gene was up-regulated significantly in the observation group (P < 0.05). In the observation group, the expression ofPTEN gene at 48 and 72 hours was significantly higher than that at 24 hours (P < 0.05). These findings indicate that in the human umbilical cord mesenchymal stem cels can inhibit the proliferation of ectopic endometrial celsin vitro and promote their apoptosis by up-regulation ofPTEN mRNA expression.
