Objective To study the relationship between white blood cell(WBC) count and cardiac events in acute ST-elevation myocardial infarction(STEMI) patients treated with reperfusion in the early stage. Methods Two hundred and thirty-five patients with acute STEMI were divided into two groups:percutaneous coronary intervention group (PCI group, 97 patients) and thrombosis therapy group (138 patients). WBC count and cardiac events of the two groups before and after treatment (3 h and the second day and the third day) were recorded and compared. Results The level of WBC count had no changes in two groups before and after treatment in first 3 h (P>0.05) , while the level of WBC count was significantly decreased, and the level of WBC count was significantly lower in PCI group than that in thrombosis therapy group (P<0.05). The rate of no cardiac events and two cardiac events in two groups has no significant differences (P > 0.05). The rate of one cardiac events in PCI group was significantly higher than that in thrombosis therapy group (P<0.05). The rate of three cardiac events in PCI group was significantly lower than that in thrombosis therapy group (P<0.05). WBC count had a positive correlation with cardiac events rate (r = 0.231, P < 0.05). Conclusions Primary percutaneous coronary intervention decreases WBC count and cardiac events rate. In patients with acute myocardial infarction, level of WBC count has positive relationship with cardiac events.

[Objective]To investigate the protective effects of calcitonin on articular cartilage and subchondral bone in experimental osteoarthritis induced by ACLT(anterior cruciate ligament transection) of rats. [Methods]Thirty 12-week-old Sprague Dawley rats were divided randomly into three groups: Sham(n=10),ACLT+CT(n=10) and ACLT+NS(n=10).ACLT+CT group received a daily subcutaneous injection of salmon calcitonin at a dose of 10 IU.kg-1.d-1 for 12 weeks,ACLT+NS group received NS at the same dose.All rats were sacrificed at 12 weeks after operation.The macro-pathological changes of Samples were graded by Mankin's scale.Bone mineral density(BMD) of right distal femoras and femora condyles were measured by dual-energy X-ray absorptiometry scanner.The decalcified right femora condyles were prepared for paraffin sections,stained with safranin-O/fast green and immunohistochemistry for MMP-13.The right proximal tibias were harvested to make undecalcified bone section for detecting the bone histomorphometry of subchondral bone.[Results](1) The Mankin score of the Sham and ACLT+CT groups were significantly lower than that of ACLT+NS group.(2) The BMD and bone mass(BV/TV,Tb.Th) of the subchondral bone in ACLT+NS were significantly higher than those of Sham and ACLT+CT groups.(3)In ACLT+ NS group,expression level of MMP-13 was significantly lower than those of Sham and ACLT+ CT groups.[Conclusion]A daily subcutaneous injection of salmon calcitonin at a dose of 10 IU.kg-1.d-1 of body weight for 12 weeks can inhibit articular cartilage degeneration of rat osteoarthritic joints,inhibitiing sclerosis of and improving the microarchitecture of subchondral bone,coupled with downregulation of MMP-13 in cartilage probably participate in this process.

A simple and sensitive assay for rapid detection of human coronavirus NL63 (HCoV-NL63) was developed by colorimetic reverse transcription loop-mediated isothermal amplification (RT-LAMP). The method employed six specially designed primers that recognized eight distinct regions of the HCoV-NL63 nucleocapsid protein gene for amplification of target sequences under isothermal conditions at 63 degrees C for 1 h Amplification of RT-LAMP was monitored by addition of calcein before amplification. A positive reaction was confirmed by change from light-brown to yellow-green under visual detection. Specificity of the RT-LAMP assay was validated by cross-reaction with different human coronaviruses, norovirus, influenza A virus, and influenza B virus. Sensitivity was evaluated by serial dilution of HCoV-NL63 RNA from 1.6 x 10(9) to 1.6 x 10(1) per reaction. The RT-LAMP assay could achieve 1,600 RNA copies per reaction with high specificity. Hence, our colorimetric RT-LAMP assay could be used for rapid detection of human coronavirus NL63.
