ObjectiveTo investigate the value of serum β2-microglobulin for diagnosis of early renal insufficiency. MethodsThe levels of β2-microglobulin and Scr were measured in one hundred and twelve patients diagnosed of nephropathy and 41 of control group.And the results were analyzed. ResultsCompared with the control group,there was significant difference in serum β2-microglobulin(all P＜0.05).The levels of β2-microglobulin of renal insufficiency were increased,include(3.51 ± 0.46)mg/L,(5.8 ± 1.13)mg/L,(12.4 ± 3.63)mg/L,and (21.3 ± 4.73)mg/L,also correlated with degree of Scr,and negatively correlated with degree of Ccr. ConclusionSerum β2-microglobulin could be used as the early diagnostic marker of early renal insufficiency.

Pediatric kidney disease prevalence has increased over the past decades.The key result of children with chronic kidney disease (CKD) is end-stage renal disease (ESRD) who needs renal replacement therapy with significantly increased risk of cardiovascular disease and metabolic syndrome.It is essential to diagnose CKD in the early phase by assessment of kidney function.We assess the kidney function by detecting serum creatinine(SCr) and blood urea nitrogen(BUN),which are traditional biomarkers and not sensitive to diagnose AKI.We also use cystatin C and β2-microglobulin to evaluate kidney function,which are controversial in clinic.It is difficult to evaluate kidney function exactly for children because glomerular filtration rate(GFR) is different in children with different age and gender.It should be more sensitive and specific to assess pediatric kidney function by applying blood and urine biomarkers and GFR equation together.Nowadays,we should find a more precise equation to evaluate GFR for children in order to monitor the kidney disease progression.It may provide the exact timing for the treatment to prevent ESRD.Therefore,we summarize some GFR equations in order to detect more suitable equation to evaluate GFR for Chinese children with different age,gender and nutrition status.

Small for gestational age (SGA) infants are defined as infant with a birth weight below the 10th percentile of the average weight for gestational age or below 2 standard deviations for gestational age.More evidences have suggested that compared with the appropriate for gestational age infants,besides the short stature,there are also higher risks of lower intelligence,poor academic performance,low social competence,behavioral problems in SGA infants.

Pseudoexfoliation syndrome (PEX) is an age-related systemic disease,with the features of fibrous stripped content widely deposit on the eye and other systemic organizations,which is associated with a rapid progress of cataract and secondary glaucoma in partial patients.The present study showed that the basement membrane injury,autoimmune disorders,and genetic factors were related to PEX,but the exact pathogenesis of PEX is still unclear.The purpose of this review was to discuss the recent progress in the pathogenesis and histopathology,expecting to contribute to the prevention and treatment of PEX.

Muscle-specific microRNAs (myomiRs) are a class of small endogenous non-coding RNAs that expressed specifically in the muscle tissue.By negatively regulating related gene expression at posttranslational level,they participate in a variety of biological processes and affects the occurrence and development of diseases.The occurrence and development of muscle-related diseases,such as chronic obstructive pneumonia disease,hypertrophic cardiomyopathy and so on,induce the expression changes of myomiRs and downstream target genes.The effects of myomiRs on the muscle contraction will affect the development of the disease.This paper will review the biological effects of common myomiRs,such as miR-1,miR-133,miR-206,miR-208 and miR-499 in muscle contraction and relaxation,including striated and non-striated muscle.Better understanding of the effects of myomiRs on the biological effects of muscle contraction and relaxation will provide a new idea for the treatment of muscle-related diseases.

Objective To discuss the maternal and neonatal outcomes in gestational diabetes patients given insulin therapy at different periods.Methods Clinical data of 52 cases of gestational diabetes patients admitted from May 2011 to June 2013 in The Central Hospital of Ningbo Development Zone were analyzed,among whom 28 cases accepted insulin therapy before 32 weeks of pregnancy(early diagnosis treatment group)and the rest 24 cases accepted insulin therapy after 32 weeks of pregnancy(late diagnosis treatment group).The pregnancy outcome,hemodynamic parameters,incidence of hypertension,and the outcome of neonates were compared.Results The blood glucose of the 52 patients was controlled in the normal range after insulin therapy.However,incidence of preterm and cesarean section was significantly higher in the early diagnosis treatment group than that in the late diagnosis treatment group (P ＜ 0.05).The incidence of neonatal ketosis,fetal distress,and the incidence of macrosomia was significantly lower in the early treatment group than that in late diagnosis treatment group (P ＜ 0.05).The incidence of pregnancy-induced hypertension had not statistical difference between the two groups of pregnant women(P ＞ 0.05).S/D value of the two groups of pregnant women had no statistical significance(P ＞ 0.05).RI and PI value was significantly higher in the late diagnosis treatment group than those in early diagnosis treatment group(P ＜0.05).Conclusions The blood glucose of patients was controlled in the normal range after insulin therapy.Insulin therapy before 32 weeks of pregnancy can improve pregnancy outcomes.However,further research is needed for specific treatment programs.

Acid sphingomyelinase (ASMase),an important enzyme for production of ceramide has been reported to be involved in the regulation of cell and organ functions and has been implicated in the development of different diseases such as diabetes,hearty disease,liver and kidney diseases.Diabetic nephropathy is a common complication of diabetes.It was found that ASMase has been closely associated with the development renal disease.Hence,it is of great importance to study the impact of ASMase on renal diseases.

It is an evasive topic on life value education post-disaster when the earthquake reconstruction has started off.Considering the experience and lessons learned from the earthquake,this article expailns the contents of post-disaster life education at school and puts forward some suggestions on how to carry on the education of life value.

Objective To study the changes of Vasodilator-stimulated Phosphoprotein phosphorylation which was dynamically regulated by cell adhesion to extracellular matrix,and to investigate the roles of VASP in the process of tumor cell adhesion and de-adhesion.Methods HeLa cells were divided into four groups: stably adherent cells,cells held in suspension,cells replated onto dishes coated with collagen I and positive control(cells treated with Forskolin).Changes in cell morphology were observed in inverted phase contrast microscope.Phosphorylation of VASP was detected by Western blot,and PKA activity was measured by PKA assay kit.(Results In) untreated,stably adherent cells,VASP was predominantly in the unphosphorylated form; Detachment of cells stimulated PKA activity and induced PKA-dependent phosphorylation of VASP;VASP was phosphorylated gradually following reattachment but returned to base level of phosphorylation during active cell spreading.Conclusion During the process of HeLa cell adhesion and de-adhesion,dynamical changes of VASP from the form of phosphorylation to dephosphorylation via PKA have been observed.

Objective:To investigate the effect of curcumin on the proliferation and the protein expression of Pleiotrophin(PTN) in cervical cancer Caski cells. Methods:MTT was used to assay the proliferation of Caski cells which were treated with different concentrations of curcumin. The immunocytochemistry was used to assay the distinctive expression of PTN in Caski cells which were treated by curcumin or not. The effects of curcumin with different concentrations on the protein levels of PTN were tested by Western blotting. Results:The proliferation of Caski cells were inhibited by curcumin in a does-dependent manner.Immunocytochemistry assessment showed the expression of PTN was significant down-regulated after treated with curcumin. Western blotting showed the curcumin could down-regulate the expression of PTN,and this was a does-dependent action. Conclusion:Curcumin could inhibit the proliferation and the PTN expression of Caski cells significantly,which may be one of the molecular mechanisms anticancer of curcumin.
