Overview of "--" acupuncture, an acupuncture school of 's Zhuang medicine of Guangxi / 中国针灸

The theory of "--" of Zhuang medicine was explored and the academic achievements and experience of professor - were summarized to explain the theory and clinical characteristics of -- acupuncture, an acupuncture school of 's Zhuang medicine of Guangxi. This acupuncture method is guided by the theory of "three- synchronization" and "--" of Zhuang medicine, based on the theory of "three channels and two paths", with regulating as the method and regulating spirit as the basis. After the patient is calmed and resting, the micro needle shallow needling technique is adopted, mainly at the umbilical ring point, so as to achieve the purpose of regulating the mind and treating the root cause.

Effect of 27nt-miRNA on regulation of SM22α expression in vascular smooth muscle cells and its effect on cell viability, migration and phenotypic changes / 中国病理生理杂志

AIM:To investigate the effect of 27nt-microRNA (27nt-miRNA) on the expression of smooth muscle 22α protein (SM22α) and the cell viability, migration and phenotypic changes of vascular smooth muscle cells (VSMCs).METHODS:The highly expression plasmids of 27nt-miRNA, and anti-27nt-miRNA and negative control plasmids were constructed, packaged with lentivirus and transfected into the rat primary VSMCs.Platelet-derived growth factor BB (PDGF-BB) was added to induce VSMCs phenotype conversion.The cell viability was measured by MTT assay.The migration ability was detected by scratch assay.The mRNA and protein expression of SM22αwas determined by RT-PCR, immunocytochemical staining and Western blot.RESULTS:Compared with normal group, the cell viability in PDGF-BB group was increased (P<0.05) , the migration ability was increased (P<0.05) and the expression of SM22αat mRNA and protein level was decreased (P<0.05).Compared with negative control lentiviral group, the cell viability in 27ntmiRNA over-expression group was decreased (P<0.05) , the migration ability was decreased (P<0.05) , and the mRNA and protein expression of SM22αwas increased (P<0.05).While in anti-27nt-miRNA group, the cell viability was increased (P<0.05) , the migration ability was increased (P<0.05) , and the mRNA and protein expression of SM22αwas decreased (P<0.05).CONCLUSION:27nt-miRNA significantly increases the expression of SM22α, while inhibits the viability and migration ability of VSMCs, and inhibits its phenotypic shift from contractile to synthetic.
