Carotid stenosis is an important modifiable risk factor in ischemic stroke.The com prehensive diagnosis of carotid stenosis,including the comprehensive understanding of stenosis degree,plaque stability,and head and neck vessels,which has important guiding significance for the prevention and treatment of ischemic stroke.This article reviews the diagnostic values of digital subtraction angiography,sonography,magnetic resonance angiography and CT angiorgaphy in carotid stenosis.

In order to supply a gap of PACS which is unidirectional,frame transmission and lag,a demonstration and teaching system which can be used as the tech support of the academic exchanging,teaching,studying,and emulating on spot is developed.By this,the medical audio and video signals and images including the video of the operation process,the images from endoscopes,electron microscopes,and the pathological images etc.in the clinical buildings and in the terminal units including research and teaching(training and exchanging) centers,lecture theaters and the director's offices etc.can be transmitted synchronously and bi-directionally in real time.

Objective:To establish the emergency medical equipment rental center, not only can reduce the repeated purchase for medical equipment, but also can achieve resource sharing, reduce equipment maintenance cost, and improve utilization efficiency.Methods: To establish emergency medical equipment rental center, which adopted lease mode and centralized management mode to use equipment. Department of medical engineering managed this center and this department is responsible to ensure every clinical department can use equipment by lease method.Results: The center has optimized the resource allocation of hospital, obviously reduced equipment input cost, improved utilization rate of medical facility since it were established. This mode provided reliable service for clinical departments.Conclusion: The established rental center of emergency medical equipment has changed the traditional management mode to a new feasible mode which can improve centralized management for medical devices, reduce waste for medical resource and achieve resource sharing.

The Expert Consensus on the Diagnosis and Therapy of myelodysplastic syndrome (MDS) (2014) will be interpreted in this paper focusing on whether it is scientific and reasonable.Some advises and views will be put forward,hoping that it will be useful to improve the diagnostic and therapeutic ability on MDS for clinicians in our country.

Objective By comparing clinical efficacy of percutaneous vertebroplasty with high viscosity bone cement and percutaneous kyphoplasty with conventional low viscosity bone cement for osteoporotic vertebral compression fractures,to explore the clinical value of treatment of osteoporotic vertebral compression fractures with high viscosity bone cement.Methods In this prospective study,100 patients with one-level OVCF and older than 70 years were diagnosed and treated in our hospital from June 2014 to December 2015,which were randomly divided into 2 groups (50 patients in each),applied unilateral percutaneous vertebroplasty with high viscosity bone cement and bilateral percutaneous kyphoplasty with conventional low viscosity bone cement,respectively.Collected data of basic clinical informations (including age,gender,body mass index,etc.),preoperative and postoperative visual analog scales (VAS),Oswestry disability questionnaire (ODI),operative time,intraoperative X-ray times,the amount of bone cement injection,leakage of bone cement,anterior vertebral height and kyphosis (Cobb angle) of preoperative and postoperative,and statistical analysis.Results There were significant improvement of both VAS and ODI scores of the postoperative 1 day,3 months and 12 months compared with preoperative,but there was no significant difference between two groups;The operative time,intraoperative fluoroscopy times,bone cement injection amount and intraoperative bone cement leakage of high viscosity bone cement PVP group were significantly less than those of low viscosity bone cement PKP group (P＜0.05);the anterior vertebral height and kyphosis improved,and there was a significant difference between preoperative and postoperative of low viscosity bone cement PKP group (P＜0.05).Conclusion The efficacies of unilateral PVP with high viscosity bone cement and bilateral PKP with conventional low viscosity bone cement for osteoporotic vertebral compression fractures are the same,which can relieve pain and improve function of life significantly.However,the high viscosity bone cement PVP is simpler surgical procedure,with shorter operative time,less intraoperative radiation,less bone cement leakage rate.The domestic bone cement injection device can significantly reduce the cost of surgery,it worth to be widely used for clinical application.

Objective To investigate the clinical value and safety of thoracoscopic lung biopsy in the diagnosis of diffuse parenchymal lung diseases. Methods 35 patients with diffuse parenchymal lung disease underwent thoraco-scopic lung biopsy were reviewed in order to obtain clinical and pathological data. Results 31 cases were diagnosed by pathology, and the total positive diagnostic rate was 88.6 % (31/35), 10 cases as usual interstitial pneumonial (UIP), 6 cases as Tuberculosis, 4 cases as alveolar cell carcinoma, 3 cases as nonspecific interstitial pneumonia (NSIP), 3 cases as crypto-genieorganizingpneumonia (COP), 2 cases as pulmonary alveolar proteinosis (PAP), 1 case as Wegener's granulomatosis (WG), 1 case as acute interstitial pneumonia (AIP), 1 case as lymphangioleiomyomatosis (LAM). 3 cases (8.6 %) were occurred with postoperative complications, 2 cases as pulmonary infection combined with respiratory failure, 1 case as idiopathic pulmonary fibrosis with acute exacerbation, and 2 cases (5.7 %) were complicated with death. Conclusions Thoracoscopic lung biopsy is a safe and effective method which helps final di-agnosis of diffuse parenchymal lung disease.

The DNA demethylase genes are widespread in plants. Four DNA demethylase genes (LJDME1, LJDME2, LJDME3 and LJDME4) were obtained from transcriptome dataset of Lonicera japonica Thunb by using bioinformatics methods and the proteins' physicochemical properties they encoded were predicted. The phylogenetic tree showed that the four DNA demethylase genes and Arabidopsis thaliana DME had a close relationship. The result of gene expression model showed that four DNA demethylase genes were different between species. The expression levels of LJDME1 and LJDME2 were even more higher in Lonicera japonica var. chinensis than those in L. japonica. LJDME] and LJDME2 maybe regulate the active compounds of L. japonica. This study aims to lay a foundation for further understanding of the function of DNA demethylase genes in L. japonica.

Objective To investigate the effect of Mycobacterium vaccae vaccine combined with chemotherapy on immune function in treatment of children with pulmonary tuberculosis.Methods 89 cases with pulmonary tuberculosis from December 2010 to December 2013 treated in three hospitals in xinxiang city were randomly divided into control group and observation group.The control group was given regular chemotherapy,the observation group was given chemotherapy combined with Mycobacterium vaccae vaccine therapy.CD4 +,CD8 +,CD8 +/CD4 +and CD16 +CD56 +in peripheral blood were evaluated by FCM before and after treatment.Serum TNF- αand IL-10 levels were detected by the method of ELISA.Taking 3 sputum samples (night sputum,morning sputum and sputum at moment)of each patient to smear after treatment.Results Before treatment,there was no significant difference of each index between two groups.After treatment,CD4 +,CD4 +/CD8 +and CD16 +CD56 +in the observation group were significantly higher than that before treatment and the control group(P<0.05).The proportion of CD8 +in two groups was significantly lower than before treatment(P<0.05),the difference between groups was not statistically significant.Serum TNF- αand IL-10 levels decreased significantly in two groups than those before treatment and the control group(P<0.05).After treatment,the negative conversion rate in the control group was 90.9%(n=40),while 100%(n=45)in the observation group.The difference between two groups was statistically significant(P<0.05).Conclusion Mycobacterium vaccae vaccine combined with chemotherapy has a significant effect on children with pulmonary tuberculosis.It could significantly improve the immune function of children.
