ABSTRACT
@#With the development of biomimetic technology, more and more in vitro models are used to simulate human physiological and pathological processes.These in vitro models can solve some scientific problems, such as studying drug effects in real-timely and visually.As an in vitro model, organ-on-a-chip provides novel means and methods for basic and applied science.The vascularized organ-on-a-chip, as a special kind of organ-on-a-chip, can better simulate the structure and function of human blood vessels.In this review, we summarized the structure and function of different vascularized organ-on-a-chip, analyzed the application of vascularized organ-on-a-chip in simulating physiological and pathological processes, and discussed the advantages and problems to be solved of vascularized organ-on-a-chip as a new in vitro model.Finally, the application of vascularized organ-on-a-chip is proposed.
ABSTRACT
Objective To observe the clinical efficacy of cyclosporin and hormone in the treatment of patients with idiopathic membranous nephropathy,to provide a new choice for the clinical treatment.Methods 84 patients with idiopathic membranous nephropathy met the inclusion criteria were randomly divided into the observation group and control group,with 42 cases of each group.The control group was treated with cyclophosphamide (CTX)and prednisone,while the observation group was given cyclosporin and prednisone,both group had been treated for 12 months.Blood were exsanguinated for detecting 24h urine protein,serum albumin,creatinine,alanine aminotransferase before treatment and after treatment for 3 months,6 months,9 months and 12 months.All patients had been follow -up for 2 years for making a statistics of 2 -year cumulative recurrence rate,the short and long term clinical efficacy were compared and the adverse reactions were recorded.Results The 24h urine protein of the control group and observation group after 3 months,6 months,9 months and 12 months treatment were (5.6 ±2.6)g vs.(4.0 ±2.1)g, (4.0 ±2.2)g vs.(3.2 ±1.6)g,(3.8 ±1.4)g vs.(3.0 ±1.5)g,(3.1 ±1.6)g vs.(3.0 ±1.4)g,the observation group were significantly lower than before treatment (F =4.513 vs.6.443,all P 0.05.The adverse reaction rates of the observation group and the control group were 30.95% vs.11.91%,χ2 =4.592,P <0.05.Conclusion Cyclos-porin can effectively reduce proteinuria and increased serum albumin faster,it has better short and long term clinical efficacy,the adverse reactions is easy to monitor and control although high,it can be considered for using because of invalid or relapse for CTX.
