Objective:To establish hospital infection data sharing and service platform for collecting and issuing the hospital infection data. Methods:The relational database was used to realize data storage and J2EE light structure was employed to enhance the development and the operating efficiency and flexibility of the system according to the principles of Web information system.Results and Conclusion:An open and sharing hospital infection data platform for data processing, retrieving and analyzing was established. The established hospital infection data set and surgery infection data set contained more than 20 000 records. The system provided an effective software platform support for the utilization of hospital infection data and the prevention and control of hospital infection. This article introduces key technologies of the design and realization of the system.

Objective To evaluate the early outcomes of mini-open lumbar microdiscectomy. Methods There were 38 cases in each group of mini-open lumbar mierodiscectomy and conventional discecto- my.Operating time,blood loss,time of leaving the bed and length of hospital stay were compared in two groups.MacNab criteria were used to evaluate the outcomes.Results To compare the conventional discec- tomy group,microdiscectomy group spent similar operating time,but had less blood loss(P

Objective To evaluate the efficacy of premedication of pronase and simethicone before upper gastrointestinal endoscopy. Methods A total of 4 690 patients undergoing upper gastrointestinal en?doscopy from January 2014 to November 2014 were recruited at gastrointestinal endoscopy center in Beijing Military General Hospital. All patients were randomized into 3 groups. The pronase plus simethicone group( n=1 602) took 40 ml mixed solution of pronase, sodium bicarbonate and simethicone orally 20 minutes before endoscopy. The simethicone group( n=1 548) took 40 ml simethicone orally 20 minutes before endoscopy. And the control group( n=1 540) took 10 ml lidocaine hydrochloride mucilage orally 5 minutes before endos?copy. The visibility during gastroscopy was observed. Results Each patient underwent gastroscopy, and no severe adverse event occurred during the procedure. The visibility of 82?3%( n=1 318) of the pronase plus simethicone group, 67?7%( n=1 048) of the simethicone group and 28?1% patients( n=432) of the control group respectively reached grade A or B. The visibility during gastroscopy in the pronase plus simethicone group was higher than that in the simethicone group(χ2=89?42, P=0?000) , while that in the simethicone group was higher than that of the control group(χ2=486?30, P=0?000). Conclusion Premedication of pronase and simethicone can improve the visibility during gastroscopy.

Objective To analyze the miss rates of colorectal adenomas during colonoscopy as well as risk factors influencing the adenoma miss rates and to take corresponding measures. Methods A total of 432 patients who underwent index and follow-up colonoscopy in 18 months were randomized and investigated. The results of two colonoscopies were compared and the missed adenomas were defined as the adenomas de-tected only during the second colonoscopy. Miss rates were calculated according to patient-based methods. Chi-square test was used to analyze the relative factors influencing the adenoma miss rate of per-patient. Then the meaningful factors were chosen into the logistic regression model for multiple factors analysis. Results Of 432 patients,116(26. 9%)had missed adenomas on first colonoscopy. Single factor analysis found that the size of adenoma( χ2 = 89. 686,P = 0. 000),the shape of adenoma( χ2 = 68. 488,P = 0. 000),the location of adenoma(χ2 = 77. 055,P = 0. 000)and adenoma tissue types(χ2 = 417. 000,P = 0. 000)were the risk factors for miss rates of colorectal adenomas. Number of polyps(χ2 = 8. 450,P= 0. 038),the organi-zation type of polyp(χ2 = 10. 718,P= 0. 013)and proficiency of colonoscopists(χ2 = 56. 069,P= 0. 000), the quality of bowel preparation(χ2 = 39. 195,P = 0. 000),insertion time(χ2 = 13. 133,P = 0. 001)were also the risk factors for miss rates of colorectal adenomas. Logistic regression analysis showed that the bigger the adenoma size,the less missed adenomas(OR= 0. 341,95%CI:0. 173-0. 671). Also,the longer insertion time took,the lower the adenoma miss rate(OR = 0. 987,95% CI:0. 981-0. 994). Per-patient miss rates were lower for high-risk adenomas compared with low-risk adenomas(OR = 0. 324,95%CI:0. 154-0. 680). Adenomas happening in multiple parts of bowel easily leads to missing(OR= 3. 791,95%CI:1. 505-9. 546). Conclusion The missed diagnosis of adenomas is not only significantly associated with features of missed adenomas,but also with skills of colonoscopists,insertion time,and bowel preparation. The key is high-quality index colonoscopy to avoid adenomas missing.

Objective To investigate the endoscopic findings and treatment of gastrointestinal neu-roendocrine neoplasms.Methods Endoscopic manifestation and treatment were analyzed retrospectively in 72 patients who were diagnosed as having gastrointestinal neuroendocrine neoplasms by endoscopy and pathol-ogy from May 2011 to December 2014.Results In 72 patients of gastrointestinal NEN,rectum was most commonly involved (48 patients,66.7%),followed by the stomach (16 patients,22.2%),duodenum, esophagus and the ileocecal valve.There were certain features in rectal neuroendocrine neoplasms under endoscopy,mostly manifested by submucosal tumors.But gastric,esophageal,and small intestine NEN man-ifestations showed various forms,without specific typical features,and easy to be misdiagnosed.Some patients diagnosed as having NEN G1 or G2 underwent EMR,ESD or laparoscopy combined with endoscopy resection.Patients diagnosed as having NEN G2 or neuroendocrine carcinoma by pathology received surgical resection,chemotherapy or palliative treatment.All 50 patients underwent endoscopic treatment successful-ly.Perforation occurred in one duodenal bulbar G1 patient during ESD.No bleeding occurred during and after the operation.All patients after treatment were followed up for 15.6 +13.2 months on average with no recurrence or metastasis.Conclusion Manifestations of gastrointestinal neuroendocrine neoplasms vary under endoscopy.Some tumors that locate in mucosa or submucosa with diameter less than 1cm can be resec-ted through EMR or ESD.

Objective To evaluate the efficacy of L?Arabinose for bowel preparation before colonos?copy. Methods A total of 170 patients who underwent colonoscopy were randomized into 2 groups. The ex?perimental group (n=85) used L?Arabinose for bowel preparation, while the control group (n=85) used polyethylene glycol electrolyte solution ( PEG?ELS ) . The degree of comfort, adverse effects, and the visibility during colonoscopy were observed. Results Premedication of L?Arabinose for bowel preparation yielded to more comfort ( U=-4?349,P=0?000) , less adverse effects (χ2=29?27,P=0?000) , and similar visibility during colonoscopy ( U=-0?875,P=0?381) compared with PEG?ELS. Conclusion L?Arabinose is safe, comfortable, and effective for bowel preparation before colonoscopy.

Objective To investigate the effects of estrogen on mismatch repiar gene expression in colonic mucosa in vivo. Methods A total of 42 healthy individuals underwent colonoscopy were enrolled in the study. Half an hour before colonoscopy examination, blood sample was taken for determining the serum estradiol (E2) level. N ormal colonic mucosal tissues determined by naked eye under colonoscopy examination were taken in the right hemi colon to detect HMLH1 and hMSH2 gene expression by semi-quantitative RT-PCR and immunohistochemistry staining. Then the correlation of serum E2 levels with hMLH1 and hMSH2 expression in colonic mucosa was analyzed. Results A bimodal curve was presented for the correlation between serum E2 level in healthy individuals and hMLH1 expression in colonic mucosa. A strong positive correlation of E2 level with hMLH1 expression in normal colonic mucosa was observed when serum E2 level was more than 45 pg/ml (For mRNA, P=0. 003, r=0. 701; for immunohistochemistry positivity index, P=0. 000, r=0. 874).However there was no correlation between E2 level and hMSH2 expression. Conclusion High serum E2 level might increase the hMLH1 gene expression in colonic mucosa in vivo.
