The mesially impacted of mandibular second molar is one kind of common malocclusion in clinic.It can lead to damages to stomatognathic system.The looped uprightor is an effective tool in the treatment of this kind of malocclusion.

The disadvantages of Admas clasp include inconvenient manual adjustment and being unsuitable to the deciduous molars.The modified Admas clasp can overcome the shortcomings.

Forty-two patients with type 2 diabetes mellitus (DM) were refered to 3 groups:type 2 DM without diabetic nephropathy (DN),type 2 DM with DN in the initial stage and type 2 DM with DN in the clinical stage.Ten healthy subjects were served as control group.Plasma adrenomedullin (ADM),urinary?_1- microglobulin (MG) and?_2-MG were detected.The results showed that the level of plasma ADM rose gradually with the development of DN and was positively correlated with markers of tubulointerstiial injury such as urinary?_1- MG and?_2-MG (both P

AIM:To investigate the effect of pretreatment of stem cell factor(SCF) and granulocyte colony-stimulating factor(G-CSF) on the proliferation and the differentiation of mesenchymal stem cells(MSCs) into cardiomyogenic cells.METHODS:The MSCs,isolated primarily from bone marrow,and purified by passage culture,were obtained from the adult rats of four groups:the rats were pretreated by 5 daily injections of SCF;the rats were pretreated with G-CSF;the rats were pretreated with SCF and G-CSF;the rats were treated without any intervention.The 4th passage of MSCs was labeled by DAPI and cellular cycle analysis was conducted by flow cytometry before co-culture.The neonatal rat cardiomyocytes cultured for 3 days were co-cultured with DAPI-MSCs.The percentage of the differentiation of MSCs into cardiomyogenic cells during the five co-culture days was analyzed.The morphologic changes of MSCs and the proteins expression of cardiac myosin heavy chain(MHC) and troponin T(TnT) were recorded respectively with digital microscope camera system and immunofluorescence technique.The percentage of the differentiation of MSCs into cardiomyogenic cells was also calculated.RESULTS:The percentage of MSCs in G0/G1 phase in SCF/G-CSF group was significantly lower than that in SCF group,G-CSF group and the control group.The percentage of MHC protein-positive MSCs in SCF/G-CSF group was markedly higher than that in SCF group,G-CSF group and the control group,and that in SCF group and G-CSF group was significantly higher than control group.The percentage of TnT protein-positive MSCs in SCF/G-CSF group,SCF group and G-CSF group was significantly higher than that in control group.CONCLUSION:SCF and G-CSF show the ability to stimulate the proliferation of MSCs and induce MSCs to differentiate into cardiomyocytes.The combination of using SCF and G-CSF is more effective than using only SCF or G-CSF.
