ABSTRACT
Objective To understand the Shenzhen Dapeng new district and Longhua district 0～7 years old children in copper (Cu),zinc (Zn),calcium (Ca),magnesium (Mg),iron (Fc) and lead (Pb) 6 kinds of trace elements,in order to establish the reasonable dietary structure and provide a scientific basis for scientific and rational supplement of trace elements.Methods Collected 2 190 cases of 0～7 years old children for health physical examination in Dapeng New District Maternal and Child Health Care Hospital of Shenzhen form March to November 2015.According to the age,they were divided into the baby group (0～1 years old) of 637 cases,children group (2～4 years old) of 723 cases and preschool group (4～7 years old) of 830 cases of three groups.Used QL8000 automatic whole blood trace elements analyzer to test Fe,Zn,Ca,Cu,Mg and Pb 6 kinds of trace elements in whole blood,and the detection results were statistically analyzed and compared.Results Test results of 5 kinds of whole blood trace element(Fe,Zn,Ca,Cu,Mg) had different degrees lack in 2 190 cases of children aged 0 ～7,and lack of different level,lack of rate were 36.26％,32.83％,14.20％,0.64％ and 0.50％,respectively.Fe and Ca deficiency in young children group was most serious,lack of Zn in infant group was most serious,other microelement lack rate had no statistically significant difference between different groups (P＞ 0.05).Pb poisoning rate was 15.71％,the Pb poisoning rate decreases along with the age growth,and boys than girls,the difference was statistically significant (x2=3.15,P ＜0.05),different gender children other microelement lack rate differences had no statistical significance between the results.Conclusion The whole blood trace element of 0～7 years old children had different lack,mainly by Fe,Zn and Ca deficiency in Shenzhen Dapeng New District and Longhua District.But Children's Pb poisoning problem could not be ignored.Therefore,to streng then the 0～ 7 years old children's whole blood trace elements level survey,microelement lack of prevention and treatment of children is of great significance.
ABSTRACT
Objective To study and investigate the detection value of noninvasive cerebral hemodynamics and serum nerve func‐tion indexes in the patients with craniocerebral injury .Methods Totally 64 patients with craniocerebral injury in our hospital from September 2013 to May 2015 were selected as the observation group ,meanwhile 64 healthy persons with the same age were selected as the control group .Then the noninvasive cerebral hemodynamics and serum nerve function indexes were compared between the two groups ,furthermore the detection results in the observation group were compared among the patients with different severity de‐grees and intracranial pressures .Results The middle cerebral artery blood flow indexes of the observation group were all higher than those of the control group ,the serum nerve function indexes were also higher than those of the control group ,and the middle cerebral artery blood flow indexes and serum nerve function indexes of the observation group had obvious differences among the pa‐tients with different severity degrees and intracranial pressures too (P< 0 .05) ,showing statistical significance .Conclusion The noninvasive cerebral hemodynamics and serum nerve function indexes have highe detection value in the patients with craniocerebral injury ,and have active clinical role for the understand of disease severity degree and intracranial pressure situation .
