The pharmacological effects and clinical applications of fish oil preparations were reviewed. Fish oil is a natural material. Its excellent clinical tolerance and multiple pharmacological activities make it a pharmaceutical of broad prospects. Fish oil preparations have been used in the therapy and prevention of hyperlipidemia and atherosclerosis in diabetics. They have also been proved effective in improving symptoms of burns and abscesses. Additionally,fish oil preparations can replace non-steroidal anti-inflammatory drugs in the therapy of immune system disorders and have effects of slowering aging and improving the memory faculty of the aged. Applications of fish oil in organ transplantation have also been reported.

Objective To explore the clinical significance of preserving the intercostobrachial nerve (ICBN) in the radical resection of breast cancer. Method All of 140 cases of breast cancer with Ⅰ - Ⅲ a stage operable eligible,were randomly divided into the experimental group with 79 cases (7 cases were rejected, 1 case was lost) that patients received radical resection of breast cancer with preservation of ICBN,and the control group with 61 cases (2 cases were lost) that patients received routine radical resection of breast cancer based on the time of admission. Analyzed postoperative local recurrence and compared to sensory dysfunction of the two groups. Results There was no significant difference between the two groups of patients in the rate of postoperative local recurrence [0-4.2% ( 3/71 ) vs. 0-3.4% (2/59)] ( P ＞ 0.05 ). The local sensory disturbance of the experimental group [2.8% (2/71 )-11.3% (8/71)] was significantly lower than the control group [54.2%(32/59)-71.2%(42/59)], there was significant difference between the two groups (P ＜ 0.01 ). Conclusion Radical resection of breast cancer with preservation of ICBN is an ideal operation in breast cancer.

Objective To assess and analyze the current status of clinical guidelines for hypertension in the world by using the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument.Methods The clinical guidelines for hypertension were identified and approved by searching China hownet,WANFANG database,PUBMED database,MEDLINE,Embase and related institutions and authorization web site from 1995 to January 2012,and relevant Web sites of agencies and organizations that produce and/or endorse guidelines.Names of the guidelines,published years and organizations,methodology of development and reference number were descriptively analyzed.AGREE instrument was used to evaluate the qualities of latest edited clinical guidelines for hypertension in countries all over the world.Results Nine guidelines were enrolled.The results showed that the hypertension guidelines scored the highest average of 88.4％ for clarity of presentation and reliability field; for applicability fields,scored an average of 86.1％; the scope and goal field scored an average of 83.8％; participants field scored an average of 71.7％; editorial independence field scored an average of 64.1％ ; rigor of development field scored the lowest average of 62.9％.The overall assessment showed that NICE 2011,Canada 2012,ESC 2009,Australia 2010 editions were the positively recommended guidelines,JNC7,Japan 2009,China Taiwan 2010,China 2010,South Africa 2011 editions were the recommended guidelines (still need to supplement and improve).No recommend or uncertain guide was found.Conclusions The quality of the hypertension guidelines is higher in general,but some common deficiency in the rigor of development and editorial independence in Asian and African guidelines formulated by the states still exists.There still exist certain gaps in evidence-based medical requirement.And the contents and quality are needed for further regulating and enhancing.A set of scientific systemic hypertension clinical guidelines evaluation system should be established.

Objective To explore the high risk factors, pathogenesis and methods of early diagnosis of periventricular leukomalacia(PVL) in premature infants.Methods The history of intrauterine hypoxia-ischemia was investigated in premature infants;TORCH-IgM antibodies in cord blood of premature infants were measured by ELISA; Nitric oxide (NO) levels in their cord blood were determined by nitric acid reducing enzyme means. Results Thirty-nine of 52 premature infants in PVL group had a history of intrauterine hypoxia-ischemia; TORCH-IgM antibody positive rate in cord blood of premature infants in PVL group was significantly higher than that in control group(P

Objective To summarize the cytological features of breast carcinoma by fine needle aspiration and differential diagonsis of breast hyperplasia and breast flbroadenoma. Methods Cytological features about 175 cases of breast cancer were analyzed,contrasted with 76 cases of breast hyperplasia and 93 eases of fibroadenoma. And 20 cases of low-diagnosis breast cancer were analyzed, compared with 13 cases of excessive diagnosis. Results The followings were found:disorderly arranged cells in 169 cases of breast cancer, about 96.9% in 175 cases,loose distance between the nucleus in 125 cases of all cases (about 71.4%). The percentage of small groups or scattered cells, medium size cells, round nucleus and irregular border nucleus was 34.3% (60/175) ,81.1% (142/175), 88.6% (155/175) and 28.6% (50/175) respectively. The nucleus/cytoplasm ratio was increased in 105 cases of all (about 60%). The nucleus/cytoplasm ratio was obviously reduced in 15 cases of all (about 8.6%). Big nucleolis were observed in 49 cases of all (about 28%). There was significant difference between nucleus size in 136 cases of all (about 77.7%). There was not myoepithelial cell in 168 cases of all (about 96%). The percentage of visible necrosis, scsttered round nucleus and integrity of cytoplasmic was 13.7% (24/175) ,89.7% (157/175), 66.9% (117/175) respectively. The cases of all above features were significantly more than those of breast hyperplasia and breast fibroadenoma (P <0.05). The percentage of large number of cells was 52.6% in 175 breast cancer cases,higher than 5.3% in 76 breast hyperplasia cases. There was a significant difference(P <0.05) between two groups. In 20 cases of low-diagnosis breast cancer the percentage of round nucleus with integrity of cytoplasmic, special arrangement cells was 70% (14 cases) ,35% (7 cases) ,higher than the cases in 13 excessive diagnosis cases. There was a significant difference(P < 0.05) between two groups. Conclusion The cell morphological characteristics of breast caner by fine needle aspiration are large number of cells, loose distance between the nucleus, disorderly arranged cells, small guoups or scattered cells, integrity of cytoplasmic, increased nuclear, round nuclear, irregular border nucleus,increased or decreased nucleus/cytoplasm ratio, big nucleoli, significant difference in nuclear size, no myoepithelial cell, visible necrosis. Most of breast cancer can be distinguished from breast hyperplasia and breast fibroadenoma by above characteristics. All those cytological characteristics are helpful to identify difficult case.
