Research Progress on Blood Biomarkers to Forecast Kidney Injury in Children with Henoch-Schonlein Purpura

HUANG Sai-pingZHOU Tai-guang.Department of Pediatric,the Affiliated Hospital of Luzhou Medical College,Luzhou 646000,China

    Abstract  Henoch-Schonlein purpura(HSP) is a common disease in children,which could develop into Henoch-Schonlein purpuritic nephritis,or even severe renal injury and resulted in renal failure and can seriously affect childrens life quality.Currently,the most reliable method to diagnose HSP kidney damage is renal biopsy,which is with high risk and piercing damage,thus not well accepted by children and their parents.Recently,with the progress of the research on proteomics and gene molecular biology,more attention is paid to sensitive blood biomarkers which could predict severe kidney damage in children with HSP.This article reviews the interrelated research progress.

    Abstract  Objective  To analyze the relationship between the urinary microalbumin/creatinine ratio(UACR) and lipoprotein(a)Lpa)〕in elderly type 2 diabetic(T2DM) patients.Methods  A total of 106 elderly patients with T2DM and 30 patients with other diseases who were treated in our hospital form January 2011 to October 2012were selected as study participants.T2DM patients were divided into diabetic nephropathy group(UACR30 mg/g50 cases) and non-diabetic nephropathy group(UACR30 mg/g56 cases)while cases with other diseases were selected as the non-diabetic control group.The biochemical indexes and urinary microalbumin were detected among all casesthe correlation between indexes and UACR was analyzed by Pearson correlation analysisrisk factors for UACR among T2DM patients were analyzed by Logistic regression analysis.Results  There were significant differences in levels of low density lipoprotein cholesterol(LDL-C)apolipoprotein B(ApoB)Lp(a)ureacreatininefasting blood glucose(FBG)glycosylated hemoglobin(HbA1c) and UACR among three groups(P0.05).In non-diabetic control group and non-diabetic nephropathy groupthere was no correlation between Lp(a) level and UACR(r=-0.290P=0.120r=0.163P=0.230).In diabetic nephropathy groupLp(a) level was positively correlated with UACR(r=0.363P0.01).Single factor Logistic regression analysis showed that the diabetes durationdiastolic blood pressurelevels of LDL-CApoBLp(a)HbA1c and fasting C peptide(FCP) were possible risk factors for UACR(P0.2).The multivariate Logistic regression analysis showed that FCP leveldiabetes duration and Lp(a) level were independent risk factors for UACR(P0.05).Conclusion  In patients with diabetic nephropathyLp(a) level are positively correlated with UACRand Lp(a) level is one of the independent risk factors for UACRso Lp(a) level can indirectly reveal the kidney damage in T2DM patients.

Effects of Pressure Titration by Two Different Configurations on the Treatment Compliance of OSAHS Patients Undergoing Nasal CPAP

CUI Xiao-chuanSHI Ling-zhiHUANG Li-rong,et al.Department of RespirologyPeoples Hospital of WuxiWuxi 214023China

    Abstract  Objective  To investigate the effects of two pressure titration methods by monitoring of overnight polysomnography(PSG) and overnight pulse oximetry on the treatment compliance of OSAHS patients undergoing nCPAP.Methods  66 moderate to severe OSAHS patients(AHI20/hour) who were willing to take pressure titration nCPAP treatment were divided into two groups with randomly single-blinded method.The 31 cases in group A was given pressure titration by PSG monitoring,while the 35 cases in group B was given pressure titration by overnight pulse oximetry monitoring.The results of pressure titration of the two groups(AHI,minimum pulse oximetry,pressure and mask air leakage) and treatment compliance of nCPAP(regular usage rate of machine,average usage hour per day and average usage days per month) were compared between the two groups.Results  AHI,minimum pulse oximetry,pressure,mask air leakage,regular machine usage rate,average machine usage hour per day and average machine usage days per month showed no statistically significant difference between the two groups(P0.05).Conclusion  Although the monitoring methods of pressure titration are different,the outcome of titration and patients compliance to the therapy are not affected.Since the overnight pulse oximetry is more cost-efficient and easier to be managed than PSG,it should replace the PSG in clinical application.

ZHANG Wei,ZHANG Chen-yu,YANG Zhi-qiang,et al.Liaoning Medical University,Jinzhou 121001,China

    Abstract  Objective  To detect the expression of small breast epithelial mucin(SBEM) and focal adhesion kinase(FAK) in triple-negative breast cancer(TNBC) tissues,and to explore the correlation between the two and their clinical significances.Methods  Paraffin specimens of 67 cases diagnosed as breast cancer from 2005 to 2007 in the First Affiliated Hospital of Liaoning Medical University were collected.Immunohistochemical staining was used to detect the expression of SBEM and FAK in TNBC tissues.Contingency tables independence χ2 test was used to analyze the correlation between the two,Kaplan-Meier survival analysis was used to conduct survival analysis and Cox proportional hazards model was used to conduct multivariate analysis for prognostic factors.Results  The positive rate of SBEM and FAK was 52.2%(35/67) and 68.7%(46/67) respectively in TNBC.Histological grade,lymph node metastasis and Ki67 were correlated with the positive expression of SBEM and FAK in TNBC(P0.05),while menstrual status,age and tumor diameter were not correlated with their positive expression(P0.05).SBEM was correlated with FAK,with a contingency coefficient of 0.438.The disease-free survival(DFS) of the SBEM positive group was 21.4 months,and the overall survival(OS) was 28.9 months.The DFS of the SBEM negative group was 23.3 months,and the OS was 35.6 months.The difference was statistically significant(P0.05).The DFS and OS in the FAK positive group were 20.7 months and 25.4 months respectively,and the DFS and OS in the FAK negative group were 22.9 moths and 32.5 months respectively,showing statistically significant difference(P0.05).The 5-year DFS of the 67 TNBC patients was 7.5%,and the 5-year OS was 13.4%.Multivariate analysis by Cox model showed that histological grade,lymph node metastasis,Ki67,SBEM and FAK were independent prognostic factors of 5-year DFS and 5-year OS(P0.05).Conclusion  SBEM and FAK may play an important regulatory role in the occurrence and development of breast cancer,and are the prognostic factors of TNBC adverse prognosis.The positive expression of SBEM and FAK in TNBC are correlated,the combined detection of the expression of the two may provide references for the metastasis and prognosis of TNBC.

WANG Ya-jiao,SU KeLONG Yanet al.Department of EndocrinologyHospital Affiliated to Guilin Medical CollegeGuilin 541004,China

    Abstract  Objective  To explore the effects of blood glucose fluctuation and calcitonin gene-related peptide(CGRP) on kidney diseases in diabetic rats.Methods  40 Sprague-Dawley(SD) rats were randomly divided into control group(group A),normal blood glucose fluctuation group(group B),stable high blood glucose group(group C) and fluctuant blood glucose group(group D).Diabetes rats in group C and group D were induced by intraperitoneal injection of STZ by 60 mg/kg.Group D was given abdominal subcutaneous injection of insulin by 1-2 U at 8:30 and 14:30,while group B and group D was given intragastric administration of glucose by 2 g/kg at 800 and 1400,2.0 ml once for the blood glucose fluctuation model.Nine weeks later,weight,kidney index(KI),mean blood glucose(MBG),standard deviation of blood glucose(SDBG),largest amplitude of glycemic excursions(LAGE),24 h urinary albumin,blood urea nitrogen(BUN),serum creatinine(Cr),HbA1c,blood CGRP were determined and the change of kidney microstructure was observed by microscope.Results  Compared with group A and group B,the KI,MBG,SDBG,LAGE,24 h urinary albumin,BUN,Cr and HbA1c were increased,while the weight and CGRP were decreased in group C and group D(P0.05).Compared with group C,the KI,SDBG,LAGE,24 h urinary albumin,BUN and Cr were increased,and MBG and CGRP were decreased in group D(P0.05).Pearson correlation analysis showed that SDBG was positively correlated with 24 h urinary albumin(r=0.927,P0.01),BUN(r=0.883,P0.01) and Cr(r=0.825,P0.01),but was negatively correlated with CGRP(r=-0.823,P0.01).CGRP was negatively correlated with 24 h urinary albumin(r=-0.878,P0.01),BUN(r=-0.792,P0.01) and Cr(r=-0.796,P0.01).Conclusion  Blood glucose fluctuation and the decrease of the levels of CGRP are associated with the development of diabetic nephropathy.
