ABSTRACT
Gestational diabetes mellitus (GDM) is a serious threat to maternal and infant health. However, the unclear etiology and pathogenesis of GDM is the harrier of clinical intervention. In recent years, the relationship between inflammation and GDM has been widely concerned, but the conclusions are inconsistent. This paper summarizes the research progress on the association between inflammation-related indicators and GDM, in order to provide a basis for the diagnosis, treatment, or prophylaxis of GDM.
ABSTRACT
The fourth edition of the World Health Organization classification of tumors of the pituitary gland was promulgated in 2017. The revised classification emphasized the classification of pituitary tumors based on the origin of cell differentiation. The term of atypical pituitary adenoma was no longer recommended, and morphological parameters should be considered as an important prognostic feature in aggressive adenomas. Genetic profile and susceptibility of pituitary tumors were updated. And an additional novel aspect was the definition of some of the nonneuroendocrine tumors. The revised classification will help the pathologists to make better diagnosis, and contribute to improve our understanding of clinical outcomes for those patients.

ABSTRACT
Objective To investigate the feasibility of using ultrasound‐mediated destruction of microbubbles ( US+ MB) to enhance the transplantation of endothelial progenitor cells ( EPCs) to confer chronic allograft vasculopathy (CAV) .Methods Bone marrow derived mononuclear cells were isolated and induced in vitro . The abdominal aorta transplantation was performed . Four groups were divided:control group without treatment (group A) ,injection with saline (group B) ,injection with EPCs (group C) ,group D ( US+MB+EPCs) was injected with EPCs and US was applied to MB prior to the infusion . All rats were killed during 8 weeks after transplantation to enable histological examination;SDF‐1α expression was detected by immunohistochemistry ,the expression of SDF‐1αand TNF‐αin the grafted aortas were detected with RT‐PCR . Results When 8 weeks after EPCs transplantation ,there was a significant improvement in aortic intima of Group D compared with Group B and C ,respectively ( P <0 .05) . In addition ,treatment of Group D significantly increased the expression of SDF‐1αand reduced the expression of TNF‐αin the grafted aortas . Conclusions US‐mediated MB destruction prior to EPCs transplantation into the grafted aortas can improves the effectiveness of endothelial repair and delay the progress of CAV .
