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 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.

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 investigate the clinical characteristics and currently treatment status of intractable ulcerative colitis (IUC). Methods A retrospective analysis was conducted on the data of inflammatory bowel disease patients, who were hospitalized in Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University, from January 1999 to December 2009. According to the reaction to glucosteroids (GCS) treatment, they were divided into GCS effective group and intractable group. The general data, lesion, clinical symptoms and laboratory findings of these two groups were compared.Further treatments and the results of intractable group were analyzed. Results Totally 234 UC patients were enrolled, of which 37.6％ (88/234) patients received GCS treatment, intractable group and effective group took up 23.9％ (21/88) and 76.1％ (67/88) respectively. There was no significant difference of lesion between two groups (P＞0.05). Compared with effective group, the proportion of intractable group was higher in moderately severe bellyache[38. 1 ％ (8/21) vs 13. 4％ (9/67), P＝0.012, OR＝3.97, 95％CI:1.29～12.23], anemia[61.9％(13/21) vs 32.8％(22/67), P＝0.018,OR＝3.32, 95％CI:1.20～9.20], thrombocytosis[57.1％(12/21) vs 29.9％(20/67), P＝0.023,OR＝3.13, 95％ CI: 1.14 ～8.61]and hypoalbuminemia[38.1 ％ (8/21) vs 11.9％ (8/67), P＝0.007, OR＝4.54, 95％CI: 1.44～ 14.32]. Some patients of intractable group could be remission through extending period of GCS treatment, adding the immunomodulators or biological agents and intestinal segment excision. Conclusion UC patients with moderately severe bellyache, anemia,thrombocytosis, hypoalbuminemia at the onset of disease, which may indicate relatively poor response to GCS treatment. Immunomodulators, biological agents and surgery are the further treatment for IUC patients.

Objective To evaluate the serum 25-hydroxy vitamin D 3 level in newly diagnosed type 2 diabe-tes,and its relationship with function of islet beta cell .Methods 60 newly diagnosed type 2 diabetes patients and 48 normal glucose tolerance healthy control cases were selected .The level of serum 25-hydroxy vitamin D3 of two groups were measured using the way of high performance liquid chromatograph .The difference was compared between two groups.Insulin resistance index(HOMA-IR) and islet beta cell secrete index(HOMA-β) was used to respectively es-timate insulin sensitivity and islet beta cell function in type 2 diabetes group .The correlation was analyzed between 25-hydroxy vitamin D 3 and fasting blood glucose ,HOMA-IR,HOMA-β.Results The level of serum 25-hydroxy vita-min D3 (28.68 ±1.61) ng/mL in type 2 diabetes group was significantly lower than that of control group (41.30 ± 1.12)ng/mL(t=3.47,P<0.01).There is negative correlation between 25-hydroxyl vitamin D3 and fasting glucose (r=0.48,P<0.05).There was positive correlation between 25-hydroxy vitamin D3 and HOMA-IR(r=0.52,P<0.05).There was no correlation between 25-hydroxy vitamin D3 and HOMA-β(r=-0.06,P>0.05).Conclusion The level of 25-hydroxy vitamin D 3 was significantly low in newly diagnosed type 2 diabetes patients .Low serum 25-hydroxyl vitamin D 3 level affects islet beta secretion cell function ,the supplementation of vitamin D 3 may be a simple and effective method to reduce the ocurrence of type 2 diabetes .
