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.

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.

Objective To evaluate the clinical effects and adverse reaction of raltitrexed combined with radiation for esophageal carcinoma in elderly patients.Methods Sixty patients were randomly divided into two groups by the envelope method, 30 patients in experimental group received raltitrexed combined with radiotherapy and 30 patients in control group received radiotherapy only.Patients in both groups received conventional radiotherapy with a total dose of 56-60 Gy/28-30 F.In experimental group, raltitrexed 2.6 mg/m2 was administered concurrently with the radiotherapy on d1 and d22.Two cycles of concurrent chemotherapy were administered during radiotherapy.The short-term effects, survival times and adverse reactions of the two groups were compared.Results The total effective rates of experimental group and control group were 93.3% and 73.3%, respectively, and there was statistically significant difference between the two groups (χ2=4.320, P=0.038).The median survival times of experimental group and control group was 24.0 months and 12.0 months, respectively, and there was statistically significant difference by Log-rank test (χ2=6.048, P=0.014).The major adverse reactions of grade 3-4 in experimental group and control group were radiation-induced esophagitis (10.0% vs.3.3%;χ2=0.268, P=0.605), leukopenia (13.3% vs.10.0%;χ2=0.000, P=1.000), thrombocytopenia (3.3% vs.0;P=1.000), nausea and vomiting (6.7% vs.0;χ2=0.517, P=0.472), and the differences were not statistically significant.Conclusion Raltitrexed combined with radiotherapy can enhance the short-term effect and prolong the survival time for the elderly esophageal carcinoma patients, and the adverse reactions are mild.It is worthy of further clinical study.

OBJECTIVE To study incidence of metallo-beta-lactamase(MBL)-producing Pseudomonas aeruginosa and their drug sensitivity.METHODS A total of 323 isolates of P.aeruginosa from Nanshan District of Shenzhen between Jun 2007 and Jun 2008 were subjected to susceptibility testing against various antibiotics and identified by ATB-Expression.Imipenem and meropenem resistant isolates were selected for the detection of MBL production by disc synergia test.Enhancement of inhibition zone around imipenem and meropenem discs impregnated with EDTA was found to confirme MBL production.RESULTS Totally 323 P.aeruginosa were isolated and MBL-producing accounted for 46(14.3%),drug resistance rate to imipenem and meropenem was respectively 45.4% and 26.3%.Colistin was the most sensitive to P.aeruginosa(96.9%).CONCLUSIONS Our findings show it needs to detect MBL producers,judiciously use carbapenems to prevent their spread.
