The paper analyzes the problems of data quality of the population health information platform and the causes,constructs the data quality control and evaluation system from the aspects of evaluation model,data quality evaluation,process tracking and feedback,provides guarantee for improving data quality of the platform,and thus lays a solid foundation for sharing and application of big data of health care.

The segmental distribution of sensory and motor neurons in Neiguan (内关P6) acupoint areas was studied respectively in 8 rabbits with a horseradish peroxidase (HRP) method. The labeled neurons were found in C5-T1 segments of the spinal ganglia and in C7-T1 segments of the spinal cords (injected sides). Most labeled neurons were found concentrated in C8 and T1 of the spinal ganglia, and principally located in the circumferental areas of the spinal ganglia (47.27%). In spinal cord, the labeled neurons were located in the lateral areas of the ventral horns and the juncture of it and the lateral horns (Ⅷ-Ⅸlayers). In addition, the relation of the relative specifity of acupoints to the distributional segments of the neurons and its concentration was discussed.

Fundus photograph,angiography,optical coherence tomography,ultrasonography and other image technology and visual electrophysiology can provide a wealth of information for the diagnosis and treatment of pediatric retinal diseases.However,it put forward higher requirements on pediatric retinal imaging equipment and techniques which will be quite different from adult,because of pediatric retinal disease has its own characteristics,such as disease spectrum,pathogenesis,and pathophysiology.The principles and methods of image results interpretation on adult were not quite ready for children.It is necessary to further study the fundus imaging techniques suitable for children,gradually establish standardized examination procedures and clinical interpretation system,to promote the diagnosis of retinopathy in children.

Aging changes of tyrosine hydroxylase (TH) -immuno reactive neurons in the locus coeruleus were examined in young (3 month-old). adult(12 month-old) and aged(20 month-old) Wistar male rats, using the IGSS method and image quantitative analysis. The results obtained are as follows: ① The number of TH-immunoreactive neurons docreased markedly (P

Objective To evaluate the diagnostic value of microRNA-499 (miR-499)levels in acute myocardial infarction (AMI)diagnosis.Methods Retrieve Articles,Wanfang,China Knowledge Network,NCBI PubmMed,EMBSASE database 2010~2015 years met the inclusion criteria published abroad in relation to miR-499 diagnosis ten cases of human AMI litera-ture.The quality of the sudies was evaluated by QUADAS tools through a comprehensive analysis of the random effects model effect size,the use of meta-disc 1.4 software for statistical analysis software.Results Ten studies met the included criteria.The summary estimates for miR-499 diagnosis of MI sensitivity was 83% (95% CI,0.81 ~ 0.85),specificity of 81% (95% CI,0.78~0.83),positive predictive value of 4.53 (95% CI,3.12~ 6.58),negative predictive value was 0.22 (95% CI,0.14~0.33),diagnostic odds ratio 22.73 (95% CI,10.78~47.93).The area under the curve (AUC)for miR-499 was 0.90 with Q value of 0.84.Conclusion MiR-499 has high diagnostic value for acute myocardial infarction.

Objective To explore the changes of multifocal electroretinogram (mERG) before and after retinal detachment surgery and its clinical significance. Methods Eighteen patients suffered from rhegmatogenous retinal detachment underwent mERG before and after surgery using VERIS Science TM 4.0. The mERG at different area was compared between preoperative and postoperative surgery. Results Preoperatively, the latencies of a wave and b wave in detached area were statistically longer than in attached area ( t =4.541 and 6.784, P

Cancer stem cells (CSCs) are a small subset of cancer cells in the tumor,which possess the exclusive ability to proliferate indefmitely and multiple differentiation.These tumor cells play a crucial role in the maintenance of malignant proliferation,drug resistance,metastasis and recurrence.Majority of ocular malignancies have the properties of high recurrence,metastasis and poor prognosis.Recently,CSCs was found to exist in the ocular malignancies,also might be involved in the tumor initiation and progression.This article reviews the research progress on CSCs in ocular malignancy.

The paper takes heart disease dataset of UCI as experimental data,carries out disease diagnosis and calssification based on the deep learning technology of machine learning,compares with Random Forest (RF),Support Vector Machine (SVM) and Neural Network (NN) classification,and indicates that the Deep Learning (DL) technology is of great potential and important value for exploration of medical big data.

Objective To observe the therapeutic effect of tramadol combined with fentanyl in patient controlled intravenous analgesia after nucleotomy of intervertebral disc.Methods 60 patients under general anesthesia,scheduled for nucleotomy of intervertebral disc,were randomly divided into three group(n=20):group tramadol(group T),group fentanyl(group F) and group tramadol+fentanyl(group TF).All patients were received patient controlled intravenous analgesia by loading dose+background dose+PCA bolus dose.The BP,HR,RR,VAS at 6,12,24,48h of postoperation were observed.The sedation score in 24h,average effective-press times and drug dose in 48h of postoperation were recorded.The incidence of nausea and vomiting during 24h of postoperation were observed.Results It had no significantly difference of BP,HR,RR,VAS among three groups.The average effective-press times of group TF (8?2) were significantly less than those of group T (14?3) and group F (12?3).The drug dose of 48h was tramadol (17.9?1.5)mg/kg(group T),fentanyl (16.8?1.5)?g/kg(group F) and tramadol (11.5?0.7)mg/kg+fentanyl (9.1?0.7)?g/kg(group TF).The drug dose of group TF showed significant difference compared with others.The sedation score in group F was the highest,it had significant difference compared with the other two group.The frequency of nausea and vomiting in group T was significantly more than that in others.Conclusion Tramadol or fentanyl gived alone can afford the same satisfied analgesic effect on nucleotomy of intervertebral disc.But there is high nausea-vomiting frequency in tramadol and strong sedation frequency in fentanyl.Tramadol combined with a little opioid fentanyl can afford more satisfying analgesic effect,and is provided with advantage in less drug and side-effect.

We used SDS-polyacrylamide gel electrophoresis (SDS-PAGE), immunoblotting of monoclonal antibody (McAb) J28 and peanutagglutinin (PNA) for detecting fetoacinar pancreatic protein (FAP) in extracts of 20 cases of fetal pancreas, 5 of pancreatic cancer and 4 of normal pancreas. The result showed that fetal pancreas and pancreatic cancer had a same level band about 110000 in Commassie blue stain, but absent in normal pancreas. The band could react with both McAb J28 and PNA PNA also could react with smaller glycoprotein in pencreatic cancer. It is suggested that McAb J28 and PNA combine with different sites of FAP.
