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.

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.

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.

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.

OBJECTIVE To explore the factors and effective preventive method of nosocomial lower respiratory(infection) after general anesthesia through trachea intubation.METHODS Using bacterial culture and identification technique to detect the samples collected from pipe and the sides of anesthetic machine,from disposable virus/(bacteri)a respiratory filter and buccal and bronchial secretion of patients with general anesthesia through trachea(intubation.) RESULTS Eight of 15 anesthetic machines without disinfection were with positive bacterial culture.All sides of virus/bacteria respiratory filter,and buccal and bronchial secretion of patients during operation had same(bacteria.) No bacteria growth was found in anesthetic machine and disposable virus/bacteria respiratory filter used after operation.The same bacteria as from buccal secretion were isolated from anesthetic machine in patients(without) using virus/bacteris respiratory filter.CONCLUSIONS The(results) showed the anesthetic machine is more easy to be contaminated by patients,and the reuse of anesthetic machine is an important factor for nosocomial(lower) respiratory infection after general anesthesia through trachea intubation.Intensifying periodic disinfection of(anesthetic) machine and using virus/bacteria respiratory filter can prevent contamination between anesthetic(machine) and patients and decrease nosocomial lower respiratory(infection) after operation.
