The measurement data of high concentration sodium in food by flame atomic absorption spectrometry with deflect or no were collected and the measurement uncertainty were evaluated. The results show that uncertainty evaluation of deflect burner is smaller then no deflect burner when the food contains higher sodium. This is due to the uncertainty of dilute for many times is avoided if the burner isnu0027t deflect.

Alzheimer's disease is a degenerative brain disease and the most common cause of dementia. The characteristic symptoms of dementia are difficulties with memory, language, problem solving, and other cognitive skills which affects a person's ability to perform everyday activities. Trace elements have found to play a major role in the Alzheimer's disease. Nowadays, the association of trace elements in the pathogenesis of Alzheimer's disease is more considered, and trace elements such as aluminum (Al), iron (Fe), copper (Cu), and zinc (Zn) imbalances in the amyloid beta peptides have been seen in the Alzheimer's disease This review focuses on the accumulation of trace elements aluminum (Al), copper (Cu), iron (Fe), and zinc (Zn) in the pathogenesis of Alzheimer's disease.
A method for simultaneous determination of rare earth elements in peach bought in market by inductively coupled plasma mass spectrometry( ICP- MS) was proposed. Sixteen rare earth elements in peach sampes were determined with nitric acid- hydrofluoric acid- hydrogen peroxide by microwave digestion. The detection limits were between 0. 004 ~ 0. 020 μg·g- 1. The precision of the method and the recovery were in the range of 0. 78% ~ 2. 96%( RSD) and 95. 0% ~ 106. 0%,respectively. The proposed method has been used in the investigation of rare earth elements distribution in peaches and the results showed that the concentration of rare earth elements in peach skin was significantly higher than that in peach pulp. The method was rapid,accurate which could be used for the determination of rare earth elements in peaches and other fruits.

Methods 110 cases of chronic asymptomatic carriers of hepatitis B virus in pregnant women from January 2013 to January 2014 were treated in our hospital as research subjects,were divided into groups according to the degree of infection 1( high replication infection group) and Group 2( low copy infection group),before and after the birth of multiple injections of hepatitis B DNA vaccine,monitoring of HBV infection markers( HBVM) and HBV- DNA. Results Group 1 PMTCT was 65 cases( 97. 01%),intrauterine infection 2 cases( 2. 99%),Group 2 PMTCT rate of 43 cases( 100%),two sets of maternal hepatitis B average blocking was 98. 51%,an average of two intrauterine infection was1. 495%; when the birth of the first group and the second group of anti- HBs positive rate of up to68. 66%,respectively,93. 02%,while the first group and the first six months two groups of anti--HBs positive rate reached 94. 03%,respectively,100%,two anti- HBs( +) average of 97. 01%.Conclusion By mid- pregnancy,postpartum hepatitis B PMTCT implementation of multiple integrated intrapartum interventions to improve the rate of hepatitis B PMTCT,effectively blocking the mother to child transmission.
Objective To explore the diagnostic value of detection of HCMV in infant pneumonia and clinical application. Methods In 2013 January- December 180 cases in our hospital diagnosis for children with infantile pneumonia and serum HCMV Ig M and urine hcmv- dna detection,respectively by enzyme linked immuno capture assay( ELISA) and fluorescence quantitative polymerase chain reaction( PCR) to collect serum and urine were detected. Results 180 cases of pneumonia in infants diagnosed as HCMV infection in 72 cases,of which 54 cases of serum HCMV- Ig M positive,positive rate was75%,62 cases of urine HCMV- DNA positive,positive rate accounted for 86%. To detect HCMV with clinical follow- up survey found significantly after treatment with ganciclovir and other drugs.Conclusion HCMV infection in infants with pneumonia accounted for high rate,it can provide a basis for treatment to clinical by combined detection of serum HCMV Ig M and urine hcmv- dna,helpful to early diagnosis and early treatment to reduce complications and prognosis in patients with essential.
Objective Through examination of cerebral infarction( ACI) in the serum of the patients with D dimer( DD),homocysteine( Hcy) concentration and analysis between them and the occurrence of ACI and the infarction risk severity. Methods In the 78 cases of patients with ACI patients as the research object,according to the CT scan,to the size of the infarction area divided into 3 groups( large,medium,small) infarction group. To detect the blood of patients with DD and Hcy concentrations at the time of admission,and combined with the patients clinical symptoms and CT were analyzed. Results Blood DD in the patient group,Hcy concentration,compared with the control group,ACI DD group,Hcy were significantly increased,significant differences( P 0. 001); large infarction foci in patients with DD concentration is higher than that of middle and small infarct foci area group,pairwise comparison there were statistically significant differences between the groups; and concentrations of Hcy in different stem death foci area set of pairwise comparison is not significant difference( P 0. 01). Conclusions DD and Hcy may be involved in the pathogenesis of ACI and are independent risk factors for ACI. The concentration of DD had a predictive effect on the severity of the disease,and Hcy had no significance.
