Objective To investigate the role of human cytomegalovirus (CMV) in the occurrence of drug eruptions.Methods Peripheral blood samples were collected from 44 patients with drug eruptions (including 13 severe cases) and 50 healthy human controls.Taqman fluorescent real-time quantitative PCR (RT-PCR) was performed to determine the positive rate and load of CMV DNA in peripheral blood mononuclear cells (PBMCs).Enzyme-linked immunosorbent assay (ELISA) was conducted to detect anti-CMV IgM antibodies in sera.Results The positive rate of CMV DNA was significantly higher in the patients than in the controls (65.91％ (29/44) vs.28.00 ％ (14/50),x2 =13.552,P ＜ 0.05),significantly different among patients with severe drug eruptions (11/13),patients with mild drug eruptions (58.06％ (18/31)) and the controls (x2 =16.153,P ＜ 0.05).In addition,patients with severe drug eruptions showed a higher positive rate of CMV DNA compared with patients with mild drug eruptions (x2 =13.817,P ＜ 0.05) and the controls (x2 =7.237,P ＜ 0.05).CMV DNA load was significantly higher in the patients than in the controls ((28 183.829 ± 19 527.654) vs.(3 019.952 ± 1 760.952) copies,t' =8.517,P ＜ 0.05).No significant difference was found in CMV DNA load between patients with severe drug eruptions ((554 813.389 ± 722 642.498) copies),patients with mild drug eruptions ((13 290.558 ± 14 082.356) copies)) and the controls (P ＞ 0.05).The positive rate of anti-CMV IgM antibodies was similar between the patients and controls (13.64％ (6/44) vs.6.00％ (3/50),P ＞ 0.05),but significantly different among patients with severe drug eruptions (4/13),patients with mild drug eruptions (6.45％,2/31) and the controls (x2 =7.832,P ＜ 0.05),and significantly higher in patients with severe drug eruptions than in the controls (x2 =6.409,P ＜ 0.05).Conclusions CMV infection exists in patients with drug eruptions,and might be a factor associated with the initiation and aggravation of drug eruptions.

Tensegrity structure is comprised of compression-resis tant elements and a set of continuous tensile elements that are interconnected w ith each other. The stability of such system depends on maintenance of tensional integrity inside the structure, or what has come to be termed “tensegrity”. A ccording to studies on biology, cell structures are assembled on the basis of te nsegrity mechanism. Tensegrity of cytoskeleton can affect cell shape and functio n. Furthermore, some basic rules of mechanochemical transduction in cells can be well explained using tensegrity theory.

Mizoribine(MZR), as an orally prescribed immunosuppressive agent, has been applied in the prevention of rejection after kidney transplantation.MZR requires individual dosing due to the variation of bioavailability.However, therapeutic drug monitoring (TDM) of MZR is not well developed in China, as compared to other clinically used immunosuppressive agents.To our knowledge, this is the first TDM review of MZR.Pharmacokinetic characteristic, concentration determination methods and sample selection of MZR were summarized, also the rational therapeutic window was proposed.Furthermore, gene polymorphism and population pharmacokinetics of MZR were estimated.This review will provide reference for TDM-based individual dosing of MZR in renal transplant recipients.

Objective:It is demostrated that the porous protein-mineral mechanics model could provide more accurate prediction for biomaterial properties of dentine compared with the other established models.This paper would use the model to reevaluate the mechanical properties and its interacting mechanism of human dentine.Method:By using a porous proteinmineral mechanics model,the effect from the interactions between tubules,pedtubular and intertubular matrix on dentine microstructure was discussed.Results:The dentinal micromechanical properties were dependent on the tubular direction,and the absolute values of the stresses derived from the hydraulic and gas tubular pressures increased parabolically with theincreasing diameter of the tubules.It was also found that the effective elastic constants of the dentine microstructure would vary with the aging and the distribution of mineral and collagen within peritubular and intertubular matrix of detine.Conclusions:The theoretical analyses provided in this paper demonstrated that the microstructural characteristics of tubules,peritubular and intertubular dentinal matdx could have different influences on the micromechanical properties of human dentine,which showed the validity of porous protein-mineral mechanics model,and the limitation of some models that neglected the interacting mechanism.
