Rapid on- site evaluation (ROSE) had gradually become an essential tool in interventional section, especially in pulmonary diseases. People were no longer limited to routine endoscopic operation. ROSE combined with fine-needle aspiration (FNA) enhanced the diagnostic efficiency and diagnostic accuracy of routine bronchoscopes, endobronchial ultrasound- guided transbronchial needle aspiration (EBUS-TBNA) and percutaneous lung biopsy. ROSE can read out the specimen on site , give preliminary diagnosis, and provide help for next operation. The ROSE included cytological ROSE (C-ROSE) and microbiological ROSE (M-ROSE). Now in clinic, C-ROSE was used more broadly. C-ROSE expanded the check range of routine endoscopic operation, and it had been proven to be safe and useful tools.

Recently,much interest has been focused on the clinical application and biology of tumor-derived DNA in the plasma/serum of cancer patients.Such interest has resulted in the demonstration of human papillomavirus(HPV) DNA in the plasma/serum of patients with cervical cancer(CC).The studies used different materials(plasma /serum),different DNA extraction methods and different primers to detect circulating free HPV DNA,so the positive rates varied from(6.9%) to 50%.The HPV DNA in the plasma/serum of patients suffering from CC most likely originates from the tumor itself,which will probably provide us with a new tool for CC monitoring after primary treatment,especially in patients in advanced stages.It is expected that this promising molecular tumor marker would soon be put into routine clinical use.

Objective To study the mechanism of respiratory tracts inflammation induced by the particles with an aerodynamic diameter of less than 10 ?m (PM10) and to observe the effect of high exposed group. Methods Particles were collected at kitchen, smoking-room, roadside and lake-side (the control group). Suspension of PM10 and rat models treated with PM10, kitchen oil smoke, cigarette smoke, road dust were established with a control group.

Results The counts of total leukocyte, macrophage and neutrophils in PM10-treat groups and the count of eosinophilia in road dust group increased significantly than those in control group (P

High resolution melting ( HRM) analysis is a real-time PCR based technique which can detect DNA sequence polymorphism .Immediately after routine PCR with saturated fluorescent dye , melting transition of the amplicon was monitored and fluorescence was collected .According to the different melting curve, single base differences can be distinguished .HRM is a low -cost, single -step, closed -tube, accurate and rapid method , which has aroused general concern .Rapid and sensitive detection of the clinical pathogens is critical to diagnosis of infectious diseases .However , clinical research on application of HRM in infectious disease pathogen identification and drug resistance , especially melting curve analysis based bedside technology integration will provide strong support for the diagnosis and treatment of infectious diseases.

With reference to medical personnel's infection during the prevalence of SARS, the paper offers some general information on the risks of occupational exposure of medicine. The commonly seen risks fall into four major categories, including biological risks, such as infection of hepatitis B, hepatitis C, HTV, etc.; chemical risks, such as those from antineoplastic drugs, cleaning agents, disinfectants, narcotics, dusts; physical risks, such as radiation, injury by sharp instruments, injury from heavy burden, forced body positions, etc.; and psychological risks. The paper also puts forward some proposals for safety protection: intensifying training in occupational safety of medicine, reinforcing the protection of high-risk groups of people and high-risk body parts, augmenting the supply of protective materials and the improvement of protective facilities, and setting up and perfecting long-acting protection and supply mechanisms.

Objective To explore the effect of continuous hyperglycemia on learning and memory capacity in rats, and to observe the changes of expressions of ubiquitin and apotosis-related proteins, so as to provide a relative basis for diabetic encephalopathy. Methods The male SD rats were randomly divided into normal control group and diabetes mellitus (DM) group. The DM rats was made by intraperitoneal injection of streptozocin (STZ). The capacities of learning and memory were tested by Y-maze. The structure changes in frontal lobe cortex and hippocampus were observed by Nissl's staining and immunohistochemistry. The apoptosis cell count was measured by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). The expressions of Bcl-2 and P53 were assessed by Western-blot analysis. The expression of ubiquitin mRNA was detected by reverse transcription-polymerase chain reaction (RT-PCR). Results In DM rats, the learning and memory capacities were worse than in control rats (P＜0. 05), and the apoptosis cell counts in frontal lobe cortex and hippocampus were higher than in control rats, the expression of Bcl-2 gene was reduced while the expressions of ubiquitin and P53 gene were increased (P＜0. 05). Conclusions In the frontal lobe cortex and hippocampus, the expression of Bcl-2 gene is reduced while the apoptosis cell numbers and ubiquitin P53 gene expression are increased, which may contribute to neurodegeneration in DM rats.

Objective To investigate the effect of scene-style education mode in endoscopic ultrasonography examination.Methods 170 patients undergoing endoscopic ultrasonography from May 2009to December 2011 in our hospital were chosen as the research object.They were randomly divided into the control group(conventional education mode group)and the observation group (scene-style education mode) with 85 cases in each group.The repeated rate of insertion,rate of complication,compliance degree,the POMS scale score,blood pressure and heart rate for the two groups of patients were compared.Results Compared with the control group,the repeated rate of insertion,rate of complication were lower,blood pressure and heart rate were lower,and compliance degree and POMS mood scale score were better in the observation group,there were significant differences.Conclusions The scene-style education mode can improve negative emotions of patients undergoing endoscopic ultrasonography significantly,it also plays a positive role in increasing their compliance degree and easing stress response.

Background and purpose: MicroRNA(miRNA) is a class of small non-coding RNA playing an important regulatory role in many diseases. In this study, we explore the levels of miR-192 and zinc ifnger E-box binding homeobox 2 (ZEB2) in CRC, the clinical signiifcance of miR-192 and the correlation between the expression of miR-192 and ZEB2 protein. Methods: The expression levels of miR-192 and ZEB2 mRNA in 30 colorectal carcinoma samples, 30 corresponding cancer-adjacent tissue samples (from the edge of tumor≥5 cm), 25 colorectal adenoma samples, and 15 normal tissue samples were quantiifed using quantitative real-time polymerase chain reaction (qRT-PCR). ZEB2 protein expression was determined using Western blot. The relationship between the miR-192 and clinicopathological factors, miR-192 and ZEB2 protein expression was analyzed. Results:Signiifcant upregulation of miR-192 expression and reduction of ZEB2 mRNA and protein expression were identiifed in CRC tissues, compared to cancer-adjacent tissues, colorectal adenoma samples, and normal tissues (P<0.05). Low miR-192 levels were signiifcantly associated with lymph node (P=0.021) and distant metastasis (P=0.023). An inverse relationship between miR-192 and ZEB2 protein expression was identified in CRC group (r=-0.365, P<0.05). Conclusion: MiR-192 downexpression was correlated with CRC metastasis. MiR-192 may play a role in the development and progression of CRC through ZEB2.
