Aim To evaluate the effects of aspirin on the expression of inflammatory proteins induced by oxidized low-density lipoprotein(ox-LDL) in human vascular endothelial cells (HUVECs). Methods HUVECs were stimulated with different concentrations of ox-LDL. The expression of inflammatory proteins was detected by Western blot.Intracellular ROS generation was measured by flow cytometry using perexide-sensitive flurscent probe 2′, 7′-dichrofluorescein diacetate(DCFH-DA).Results ① Aspirin inhibited COX-2 expression induced by ox-LDL. Cells were preincubated with 2.5 mmol?L-1, 5 mmol?L-1 of aspirin or without any treatment for 30 min and then stimulated by 0.3 g?L-1 ox-LDL for 16 h, COX-2 expression was reduced by treating of aspirin.COX-2 expression was enhanced after the stimulation with ox-LDL, and aspirin inhibited the increasing.② Aspirin suppressed ICAM-1 expression induced by ox-LDL in HUVECs. ICAM-1 expression was increased by ox-LDL stimulation for 16 h, and aspirin significantly down-regulated the expression. Similar results were obtained by immunofluorescence.③ Aspirin partially reduced ROS production induced by ox-LDL in HUVECs. After stimulation with 0.3 g?L-1 ox-LDL for 16 h, the intracellular level of ROS was increased, however, aspirin failed to fully inhibit the phenomenon.Conclusion Nonsteroidal anti-inflammatory drugs (NSAID) aspirin significantly down-regulated the expression of COX-2 and ICAM-1 induced by ox-LDL.The results suggested that aspirin could reduce the inflammation responses mediated by ox-LDL on HUVECs in atherosclerosis.

Objective To investigate the neutrophil elastase (NE) in patients with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS).Methods Thirty-six patients of ALI/ARDS and 16 healthy volunteers(control group)were involved in the study.The patients of ALI/ARDS were divided into three groups:group A (the oxygenation index was 201-300 mm Hg,1 mm Hg=0.133 kPa),group B (150-200 mm Hg),and group C (<150 mm Hg).The NE in serum and bronchoalveolar Lavage fluid (BALF) were measured.Results The NE in the serum and BALF in group A [(1.76±0.63)nmol/L and (1.67±0.59)nmol/L],group B [(3.26±0.51)nmol/L and (3.64±0.56)nmol/L] and group C [(4.56 ±0.68)nmol/L and (4.62±0.39)nmol/L] were much higher than that in control group [(0.67±0.54)nmol/L and (0.62±0.48)nmol/L].The NE in the serum and BALF of dead patients were higher than that in patients who were alive.Moreover,the NE in the patients of ALI/ARDS was inversely related to the oxygenation index (r=-0.901,P＜0.01). Conclusion The NE in patients of ALI/ARDS is higher than that in healthy people,and it is significantly related to the severity and the prognosis of ALI/ARDS.

Objective To explore the value of dual-source CT monoenergetic-plus imaging in the diagnosis of early gastric cancer. Methods Imaging data of 2 6 cases with pathologically proven early gastric cancer who underwent dual-energy scanning were analyzed retrospectively.Monoenergetic-plus images with energy levels at 40 keV,50 keV,60 keV and 70 keV were reconstructed by using an advanced monoenergetic software (syngo.via.VA30A,Dual energy Mono+).Contrast-to-noise ratio (CNR)of the lesion,image noise,overall image quality score and lesion conspicuity score were com pared between different monoenergetic-plus images and conventional polychromatic images at 1 2 0 kVp.Results The CNRs (3 .2 4 ± 0 .7 6 ,2 .9 4 ± 0 .9 2 ,2 .4 7 ± 0 .7 9 ,2 .3 7 ± 0.98 and 1.22±0.40 respectively)and image noises [(32.7±1.82)HU,(25.6±2.61)HU,(20.30±2.1 7)HU,(1 7.03±2.1 5)HU and (18.15±2.12)HU respectively]among 40 keV,50 keV,60 keV,70 keV and 120 kVp groups all had statistical differences (F =24.654 and 227.05,P <0.01).The CNR in 50 keV group was higher than that in 60 keV,70 keV and 120 kVp groups,but similar to that in 40 keV group (P >0.05).The SD value in 50 keV group was lower than that in 40 keV group,but higher than that in other three groups (P <0.05).The overall image quality score (3.08±0.27,3.65±0.49,3.31±0.47,3.23±0.43 and 3.1 5±0.37,respectively) and lesion conspicuity score (4.15±0.67,3.92±0.48,3.27 ±0.45,3.08±0.27 and 3.04±0.20)among the five groups all had statistical differences (Z =25.343 and 70.426,P <0.05).The overall image quality score of 50 keV group was higher than that of the other four groups (P <0.05).Lesion conspicuity score in 50 keV group was higher than that in 60 keV,70 keV and 120 kVp groups and similar to that in 40 keV group (P =0.1 52).Conclusion The 50 keV monoenergetic-plus images can increase the CNR value of early gastric cancer while maintaining the overall image quality.

In this article, a new TCM clinical trial of phaseⅢ was served as an example of application of Clinical Data Interchange Standards Consortium (CDISC). It briefly introduced seven data acquisition modules commonly used in clinical research of new traditional Chinese medicine, namely demographics, subject characteristic, clinical event, medical history, questionnaire, laboratory inspection and adverse event. It also introduced the process of transferring the above modules to Study Data Tabulation Models (STDM), and discussed the feasibility and some issues that required attention of CDISC application in clinical research of new traditional Chinese medicine.

This paper was aimed to discuss the feasibility and attentions of application of instrumental variable (IV) methods in traditional Chinese medicine (TCM) outcome research. First, the application of IV was introduced, which included the basic principles and hypothesis, statistical model, estimator of IV and weak IV. Then, an example was given to illustrate the evaluation criteria and attentions of IV. The resultsshowed that IV method was proposed as a potential approach to the problems of confounding in statistics. But using IV methods should be based on a series of statistical hypotheses. It was concluded that the IV analysis was a method controlling confounding bias, but generally it was not chosen as the preferred analytical method. The issue of searching for valid and plausible IV seemed to be the biggest obstacle in the outcome of TCM researches.

BACKGROUND:In oral warm and moisture circumstance, al oy which contains Be is easily to be eroded to release Be2+. But there is stil no research focusing on beryl ium influence on genotype of Porphyromonas gingivalis fimbriae gene cluster. OBJECTIVE:To investigate Be 2+effect on genotype of Porphyromonas gingivalis fimbriae gene cluster. METHODS:The revived Porphyromonas gingivalis was resuscitated for 48 hours in the anaerobic culture medium with different concentration of Be 2+(10×10-6, 5×10-6, 1.25×10-6). Through PCR amplification and sequencing, we investigated the effects of Be2+RESULTS AND CONCLUSION:(1) When Be on genotypes of Porphyromonas gingivalis fimbriae gene cluster. 2+concentration was 5×10-6, we found the peak of 217 and 257 sites on DNA sequence expressing G/A overlap peak, different from G single peak of the other groups, suggesting the suspicious bases changes, part of the single base G mutated into A. (2) On al concentrations, we found a base group composed of seven A bases was inserted into the 101 site of DNA sequence. Up to now, there is no direct contacts of the mutations occurring to Be2+concentration. Changes of gene may lead to the shifting of the reading frame, the abnormal synthesis of proteins, the change of Porphyromonas gingivalis fimA gene toxicity, and lastly the unbalance of the micro-ecological environment.

ABSTRACT: Data management has significant impact on the quality control of clinical studies. Every clinical study should have a data management plan to provide overall work instructions and ensure that all of these tasks are completed according to the Good Clinical Data Management Practice (GCDMP). Meanwhile, the data management plan (DMP) is an auditable document requested by regulatory inspectors and must be written in a manner that is realistic and of high quality. The significance of DMP, the minimum standards and the best practices provided by GCDMP, the main contents of DMP based on electronic data capture (EDC) and some key factors of DMP influencing the quality of clinical study were elaborated in this paper. Specifically, DMP generally consists of 15 parts, namely, the approval page, the protocol summary, role and training, timelines, database design, creation, maintenance and security, data entry, data validation, quality control and quality assurance, the management of external data, serious adverse event data reconciliation, coding, database lock, data management reports, the communication plan and the abbreviated terms. Among them, the following three parts are regarded as the key factors: designing a standardized database of the clinical study, entering data in time and cleansing data efficiently. In the last part of this article, the authors also analyzed the problems in clinical research of traditional Chinese medicine using the EDC system and put forward some suggestions for improvement.

The Chinese clinical medical national licensing examination is the profession ad-mittance exam, which is undertake the responsibility of selecting qualified physicians. It also promotes the medical education in China. The standard for examination, the examination content, methods for measuring the Chinese clinical medical national licensing examination as well as the reform and de-velopment, has a certaln guiding role to China's medical education and medical education reform. While reviewing the medical students' performance in the examination, we can discover the weakness in medical education, which is then conducive to the promotion of teaching reform and innovation. The competence based medical licensing examination reform in China, advocating the cultivation of clinical comprehensive ability as the core content to tralning and evaluating, is conducive to continuously im-proving the quality of medical education in China, and to tralning more qualified physicians in the country.
