Objective The quantitation measurement of microalbuminuria was adopted to verify the feasibility of urinary microalbumin and ratio of mieroalbumin to creatinine (M/C) detection with dry hemieal method. Methods Totally 80 urine samples from the patients with clinically diagnosed dia-betes were tested by the immune quantitation method (immunoturhidimetric assay) and dry heroical method (HT2000 urine analyzer and test paper, Guilin Hnatong Company) simultaneously. Sarcosine oxidase method was applied to measuring creatinine level. Ten cases of outliers were removed. With the quantitation result of M/C as the reference standard, immune quatilyzation of the M/C as refer-ence, we compared and analyzed the results of the immune quantilization of urine microalbumin, those of the dry chemistry method and of the dry chemistry system detecting M/C. Results There was sig-nificant differences in test results of urinary microalbumin with the dry chemistry method and the im-mune quantitation method (P<0.01) The sensitivity, accuracy and Youden index of the microalbu-minuria testing had been observed to decrease in order in immune the dry chemistry method, the im-mune quantitation method and M/C quantitation detection method. Conclusion The sensitivity of semi-quantitation dry chemical method is satisfactory in detecting microalbumin, which may be used as a means of microalbumin screening. M/C detection with the dry chemical method isn't suitable for screening microalbumin in instant urine samples.

Acute kidney injury(AKI) is a common critical syndrome involving multidisciplinary among pediatric clinical disorders.Early identification and early intervention in severe cases with kidney damage,which can reduce mortality and improve prognosis.Renal replacement therapy(RRT) is an important means in the treatment of AKI,but there is still lacking of ideal and general modality and doses of RRT at present.Understanding the risks and benefits of each modality of RRT in the treatment of AKI is helpful to evaluate RRT's influence on the prognosis of children in AKI.Therefore the selection of modality of RRT should clinically be based on hospital conditions and specific patient characteristics,in order to assure that the choice of modality of RRT is the most suitable for the individual.

In recent years,experts of international nephrology,emergency medicine and other disciplines tend to substitute acute kidney injury for acute renal failure.There is a new point of view about the definition,diagnostic criteria,staging,management and prognosis of acute kidney injury.With diagnostic criteria constantly updated,it comes up to an expectation of united criteria as well as reaching a consensus.Continuously looking for more suitable for both time window of clinical diagnosis and clinical observation indicators,and clinically making out much more scientific and reasonable standard of diagnosis and staging,which contribute to early detection and early intervention as a result of eventually mortality rate reduction.This paper gives an interpretation for the procedure of evolution about diagnostic criteria on acute kidney injury in children according to the related literatures updated in recent years.

Objective To evaluate the efficacy of combination treatment of montelukast sodium (singulair TM ) plus mycobacterium phlei F.U.36 (wtilin"s") on young children with asthma.Methods 96 young children with asthma were randomly assigned into GroupⅠ:montelukast sodium (orally 2 5mg,q.n) plus mycobacterium phlei F.U.36 intramuscular injection for a total of 6 ampules,Group Ⅱ only montelukast sodium orally 2 5mg nightly and placebo Group.Participants were followed up for 12 weeks.Resuts Combined treatment of montelukast sodium and mycobacterium phlei F.U.36 was more effective to improve asthma in young children than the treatment with only monstelukast sodium.Conclusion The combination therapy of monkelukast and mycobacterium phlei F.U.36 is a highly effective method for preventing asthma attacks or controlling asthma.

Objective: To assess the diagnosis value of applying integrated visual and auditory continuous performance task(IVA-CPT) and EEG biofeedback on children with attention-deficit- hyperactivity disorder(ADHD), and provide information for assisting diagnosis of ADHD. Methods: 113 children with ADHD were tested with IVA-CPT and EEG biofeedback. The sensitivity, specificity, misdiagnosis rate and missed diagnosis rate of these two methods were assessed according to the criteria of DSM-Ⅳ. Results: The sensitivity of IVA-CPT for the diagnosis of children with ADHD was 92.54, the specificity was 76.09%, misdiagnosis rate was 23.911% and missed diagnosis rate was 7.46%. And the sensitivity of EEG biofeedback for the diagnosis of children with ADHD was 83.58%, the specificity was 82.61%, misdiagnosis rate was 17.38 and missed diagnosis rate was 16.42%. Conclusion: Relatively, for diagnosis of children with ADHD, sensitivity is higher and missed diagnosis rate is lower, specificity of EEG biofeedback is higher and misdiagnosis rate is lower .

Objective: To develop an HPLC-ELSD method for the simultaneous determination of six saponins constituents including notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, ginsenoside Rc and ginsenoside Rd in Xinling pills.Methods: HPLC-ELSD was used, and the chromatographic separation was performed on an Agilent Eclipse XBD-C18 column (150 mm×4.6 mm,5 μm) with acetonitrile-water as the mobile phase with gradient elution at the flow rate of 1.0 ml·min-1, the column temperature was maintained at 20℃, the drift tube temperature was 60℃, and the gas pressure was 4.00 bar.Results: Notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, ginsenoside Rc and ginsenoside Rd was linear within the range of 0.30-6.00μg(r=0.999 5), 1.14-22.80μg (r=0.999 6), 0.17-3.40 μg (r=0.999 7), 0.81-16.20 μg (r=0.999 7), 0.08-1.60 μg (r=0.999 8) and 0.07-1.40 μg (r=0.999 8), respectively.The average recovery was 98.23%, 97.98%, 99.14%, 99.15%, 98.72% and 98.37%, and the RSDs were 1.56%, 1.31%, 1.16%, 1.07%, 0.73% and 0.92%(n=6), respectively.Conclusion: The method is convenient, accurate and reproducible in the quality control of saponins components in Xinling pills

SuperparamagneticSiO2@Fe3O4microspherewithcore-shellstructurewaspreparedbythe method of hydro-thermal and St?ber method, and modified by (3-aminopropyl) triethoxysilane ( APTES) . The obtained amino-Fe3 O4@SiO2 microsphere with controlled surface charge properties was characterized by SEM and TEM, and the surface electric property of amino-microsphere was investigated by Zeta potential measurement. The microsphere was used to extract DNA from human blood, and the solid phase extraction method by microspheres was developed. The mechanism of action between Aminated-Fe3 O4@SiO2 microsphere and DNA was explored, and the gel electrophoresis and PCR test were done on the extraction product. The result showed that genomic DNA with high purity was successfully extracted from whole blood by using amino-Fe3 O4@SiO2 microsphere, with the extraction rate about 70%, the saturated adsorption capacity for DNA was about 40 ng/μg, and the elution could be directly used for further bio-analysis.
