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.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality of AR. This study supplied a new method for the comparison of extract of herbal drugs.

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.
