BACKGROUND: How to evaluate the cervical curvature correctly has been a greatly concern of spine surgeons. In recent studies, cervical curvature index(CCI) and cervical spine angle(C2-7) were often used by foreign researchers.OBJECTIVE: Ishihara method and spine angle(C2-7) method were applied to measure the cervical curvature, and the correlation between the two methods was compared as well.DESIGN: An observational controlled trial based on the patients.SETTING: Department of Orthopaedics of Peking Union Medical College Hospital.PARTICIPANIS: Totally 63 cases including 34 male and 29 female patients with cervical spondylopathy were involved in the Department of Orthopaedics of Peking Union Medical Clooefe Hospital from July 2002 to July 2003.METHODS: The 63 cervical spondylopathy patients' cervical spine lateral X-ray films were evaluated.MAIN OUTCOME MEASURES: Main outcomes: ① The patients' CCI and the cervical spine angle; ② Relationship between their CCI and the cervical spine angle. Secondary outcomes: ① Regressive equation derived from their CCI and the cervical spine angle; ② Comparison of CCI and the cervical spine angle between male and female. RESULTS: The CCI(Ishihara method) was averaged 10. 1 (SD, 11.6), and the cervical spine angle(C2 -7) 17. 5 °(SD, 13.5). A highly significant correlation was found between the two indexes( P＜0.01). Sex and age factors were found to be irrelevant to them.CONCLUSION: The CCI (Ishihara method) and the cervical spine angle (C2-7) are significantly correlated with each other.

The effects of dl-Tetrahydropalmatine ( THP ) on the physiologic properties in the auricle of guinea pig and on isoproterenol and calcium-mediated positive chronotropic action in guinea pig atria were studied.30 minutes after THP 52 nM was added, the contractility was decreased to 53+ ( SD ) 17%(P0.05) in the left auricle of guinea pig. Furthermore, the contractility and automaticity of the right auricle were decreased to 48+13% (P

Objective To discuss the nurses'satisfaction degree with work and its influencing factors and analyze the difference of nurses'satisfaction degree with work with different background.Methods 398 nurses in a certain comprehensive hospital were investigated with Mueller/McCloskey(MMSS)satisfactory inventory. Results The nurses'general satisfaction degree with work was less than middle level with a score of (3.12±0.46).The satisfaction degree was statistically different in different dimensionality and nurses with different background. Conclusion The management department of hospitals should adopt positive measures to improve the nurses'satisfaction degree with work and prompt them to supply more high-quality and effective nursing services.

OBJECTIVE: Inter-oocyte cytoplasmic transfer has been performed recently as a means to improve the outcome of assisted reproductive methods and becomes a hotspot. To overview the recent advances and problems in this area in this article, and put forth a new concept of reverse cloning technique based on ooplasmic transfer. DATA SOURCES: An online search of PUBMED was undertaken to identify correlative English articles published from January 1998 to December 2006 by using the keywords of "ooplasmic transfer, mitochondria heteroplasmy,animal cloning". Meanwhile, relevant Chinese articles published between January 1998 and December 2005 were searched in Wanfang database with the same keywords in Chinese. STUDY SELECTION:The articles were primarily screened, and the citations at the end of each reference were reviewed. Inclusion criteria: The articles related to the research of ooplasmic transfer, cloning or reverse cloning. Exclusion criteria: Repetitive studies or Meta analytical articles. DATA EXTRACTION:Totally 126 relevant articles were collected, and 31 of them were in accordance with the inclusion criteria, while 95 of them were excluded because of repetition or obsolescence. In 31 articles met the criteria, 17 studies were relevant to the ooplasmic transfer, 13 studies related to animal cloning and one study related to reverse cloning. DATA SYNTHESIS: Exciting advances have been achieved in human gamete biology, and ooplasmic transfer have been widely applied. Many studies indicated that mitochondria in oocytoplasm affected obviously the fertilization of the oocytes and early embryo development. Lots of experiments have been done on the interaction of cytoplasm and nucleus as well as the mechanism of genomic reprogramming to further the investigation. Meanwhile, the techniques are progressed. Cloning techniques is excellent in application prospect, while there are some problems at the same time. Therefore the concept of reverse cloning technique was proposed based on ooplasmic transfer. CONCLUSION: The mitochondria in oocytoplasm has remarkable effect on the fertilization of the oocytes and early embryonic development. However, ooplasm transfer can lead to mitochondria DNA heteroplasmy, and more work must be done on potential problems. The reverse cloning technique based on the ooplasmic transfer has a good prospect.

Glutamine is not only a special nutritional substance but a conditional essential amino acid,which is the most abundant amino acids in plasma,representing about 60％ of free amino acids in the body,and it's normal plasma concentration is from 0.6 to 0.9 mmol/L.In recent years,with the increasing deepening study of the field of clinical nutrition,the concept of glutamine study has been gradually changed gradually changed it's concept from a simple nutritional support to immune nutrition therapy.Glutamine can not only improve the body's protein levels of nutrition,protect the gastrointestinal mucosa,but also reduce the incidence of infection and the inflammation in the body,improve immune function,reduce side effects of chemotherapy,and at the same time enhance tumor sensitivity to chemotherapy and promote gastrointestinal cancer patients' postoperative recovery,reduce surgical complications.This paper aims to review the application and research of glutamine in the gastrointestinal cancer patients after the operation.
