Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

The ultimate goal of post-genome research is to understand a complete set of proteins in a living organism for their expression pattern and biological function,which is called proteomics.One of the major challenges in proteome research is to study the protein-protein interactions,and the emerging bioinformatics approaches present us tremendous advantages when dealing with protein interaction networking and data analysis.Useful bioinformatics tools include protein-protein interaction network mapping,topology of the network,structure of the module and comparison of the network.The technology advancement in this field brings further understandings to the structure and function of cells at the proteome level,which may eventually lead to the discovery of new drug targets and design methods.This paper attempts to review the current researches on protein-protein interaction with an emphasis on bioinformatics intervention,and also summarizes some widely used methods for network analysis.

Objective To study the prospective memory and the severity of the impairment of event- based prospective memory(EBPM)and time-based prospective memory(TBPM)in normally aging adults. Methods We set a neuropsychological battery to measure the education-matched 40 adults and 40 normally aging adults who were given EBPM and TBPM tasks.Results Compared with the young controls(EBPM, 6.25?1.60;TBPM,5.38?0.87),both EBPM(2.50?0.85)and TBPM(4.93?1.07)in the elderly had been impaired,especially EBPM(t = 13.117,P

We describe two cases in which a forceps imprintdeveloped in the AcrySof ReSTOR IOL optic whileinserting these IOLs into the cartridge with straightclamping forceps. In case 1 ,the AcrySof ReSTOR IOL wasexplanted and observed under scanning electronmicroscopy (SEM). The SEM showed that the stepdesign of ReSTOR Multifocal IOL was well maintained. Incase 2, visual acuity, contrast sensitivity and wavefrontmeasurements were performed and no specific changeswere found. Strong evidence does not exist that suggeststhe on-axis forceps imprint can significantly compromisevisual acuity.

San'ao Decoction (SD) and its analogous formulas derived in the following generations are common used prescriptions for treating pulmonary diseases with principal symptoms such as cough and asthma. They are usually compatible with Chinese herbs for facilitating Fei, dispelling wind, resolving phlegm and fluid retention. Material bases in these formulas are mainly derived from Chinese drugs, but dissolution contents of active components are changed and new components are produced after compatibility. By multilevel effect evaluation, these analogous formulas all have commonness in ventilating Fei and superiorities of evidence-based derivation. The effect pathway of commonness was involved in cell structure protection, anti-inflammation, antioxidant, and immunoregulation.

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 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 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.
