Different diagnostic criteria are existed nowadays in grading the dysplasia of gastric mucosa in clinical practice. Novel endoscopic techniques and molecular markers could facilitate the pathologic grading of dysplasia. As to the treatment strategy,it is debatable whether to choose endoscopic dissection or conservative follow-up. Here,we reviewed the diagnostic grading and therapeutic options with regard to the dysplasia of gastric mucosa.

Objective To investigate the factors associated with hyponatremia after pituitary adenoma surgery and its prognosis.Methods Clinical data of 120 pituitary adenoma patients treated in our hospital form Jan.2008 to Dec.2010 were retrospectively collected.The incidence of hyponatremia after surgery,clinicopathology and related treatment were analyzed.Results In the 120 patients,28 (23.3％) occurred hyponatremia.The blood natrium concentration recovered to normal in 7 patients within 3 days,and in 21 patients within 4 -7 days.Hyponatremia was associated with age,size of adenoma,type and diabetes insipidus early after surgery(x2 =12.6,12.4,5.38 and 6.51,Ps ＜0.05).Conclusion Hyponatremia after pituitary adenoma surgery is frequent in patients with giant pituitary adenoma,history of diabetes insipidus and older than 50 yrs.Monitoring blood electrolyte and treatment with sodium in 1 - 2 weeks after surgery would be helpful to prevent potential severe compilations.

Objective: To investigate the effects of processing and compatibility of ginger for the treatment of cold asthma rats at the metabolomics level by gas chromatography-mass spectrometry (GC-MS). Methods: The rats of cold asthma were established by ovalbumin (OVA) + ice water bath. The rats divided randomly into the control group, model group, Linggan Wuwei (fresh/dry/stir- frying) Jiangxin Decoction group and the positive drug Guilong Kechuanning group. The pathological changes of lung tissue were observed by HE staining; The inflammatory cell count in BALF and the content of IgE, IL-4 and IFN-γ in serum were determined. GC-MS was used to conduct the non-targeted metabolomics study to search the serum and urine related differential metabolites in rats with cold asthma, and MetaboAnalyst was used to construct related metabolic pathways. Results: The results showed that Linggan Wuwei (fresh/dry/stir-frying) Jiangxin Decoction improved the pathological changes of rat lung tissue, significantly reduced the BALF inflammatory cell count in BALF and IgE and IL-4 levels in serum, and increased IFN-γ levels. Compared with the control group, 37 differential metabolites (15 in serum and 22 in urine) were screened in cold asthma rats. And seven metabolic pathways involving energy metabolism, oxidative stress may be associated with cold asthma by Metaboanalysis pathway analysis. The overall metabolic profile of the cold asthma rats with the intervention of Linggan Wuwei (fresh/dry/stir-frying) Jiangxin Decoction tended to normal levels. The effect of Linggan Wuwei (dry) Jiangxin Decoction on cold asthma was better than Linggan Wuwei (fresh/stir-frying) Jiangxin Decoction. Conclusion: It is more reasonable to process ginger into dried ginger in Linggan Wuwei Jiangxin Decoction against cold asthma. Ginger processing-compatibility may play a therapeutic role in cold asthma rats by regulating energy metabolism and oxidative stress.

ISO 15189 standard quality management system developed by the International Organi-zation for Standardization (ISO) embodies the international medical laboratory's latest quality management concept, and puts forward the quality improvement method of the standard. In this research, ISO 15189, as an important content in practice teaching for laboratory medicine, was designed according to the elements of this system. Students were requested to participate in every linkage of laboratory quality management by writing system document, taking part in quality activity, and practicing the key and difficult points of tech-nique in quality system in order not only to cultivate their basic idea of ISO 15189 standard, but also to make them familiar with the basic patterns of laboratory accreditation system and process, which could make them become the backbone of the laboratory quality management quickly in their vocational positions in the future.

Objective To improve the efficiency,repeatability,expansibility and maintainability and reduce the construction and maintenance cost of the PACS.Methods Struts and Hibernate frame works based on MVC and Object-Oriented Analysis(OOA) were used to build PACS.Results It saved more time for developers,and promoted the development efficiency.Conclusion It is rapid and efficient to use Struts and Hibernate frame in building PACS.[Chinese Medical Equipment Journal,2008,29(2):55-57]

OBJECTIVE To investigate the strategy of information system in antibiotics usage management. METHODS By inquisition,statistic and analytic methods the antibiotics usage information of the hospitalized patients was recorded with the information system,to realize the realtime monitoring and process management. RESULTS The usage rate of antibiotics decreased from 88.79% to 80.19% and the prophylactic usage rate of the third cephalosporin decreased from 72.34% to 11.25%.The rational usage rate increased from 57.89% to 80.18%. CONCLUSIONS The management method of antibiotics usage with information system achieves obvious effect.

Objective To discuss the problems in the development of enterprise -Web PACS, and find the solutions. Methods The author applied the standpoint of software engineering, and used the experience of other enterprises to find a fast, low-cost, well-maintainable, well-expansible way in development of enterprise-Web PACS. Results The solution is a reasonable development method for enterprise-Web PACS, and the more big the project is, the more obvious the advantage is. Conclusion It is an effective way of developing enterprise-Web PACS to use the reasonable software structure and good development platform and advanced development framework in increasing the software reusability, maintainability, improving the capacity of the secondary development ability.

Physiologically based pharmacokinetic (PBPK) modeling is established based on the information of existing human or other animal anatomy, knowledge of physiology and biochemical data. The model uses mathematical methods to simulate chemicals′process of absorption, distribution, metabolism and excretion in the body, in order to achieve the dose and interspecific extrapolation and to predict the chemical level in the specific organ at the specific time. In studies on toxicology of nanomaterials, the PBPK models in the silver nanoparticles, zinc oxide nanoparticles, titanium dioxide nanoparticles and polymer nanomaterials are gradually established. PBPK modeling can not only provide information on the dynamic change of nanomaterials in the body, but is of great significance for to quantitative evaluation of biological safety of nanomaterials. PBPK modeling will be a hot spot for research in the field of nanotoxicology.
