Objective: To investigate the appropriateness of desflurane anesthesia used in patients undergoing intracranial operations. Methods: Sixteen patients were scheduled for removal of supratentorial mass. A radial artery catheter and a subarachanoid catheter were placed respectively prior to induetion of anesthesia. MAP, cerebrospinal pressure (CSFP), PETCO2 and HR were monitored. Anesthesia was induced with intravenous midazolan, fentanyl, propofol and vecuronium. After endotracheal intubation, anesthesia was maintained by desfurane inhalation in a concentration of 6 % (1MAC) throughout the operation. MAP, CSFP and PETCO2 were recorded before and during induction, at 20min, 30min, 40min and 50min during desflurane inhalation. Results: Compared with the baseline data recorded before anesthesia, CSFP and MAP were decreased significantly during induction. The CSFP tended to increase at 20 min after inhalation of 6 % desflurane, but remained below the baseline till 50min. MAP was decreased following inhalation of 6 % desflurane and kept relatively stable thereafter. No significnt change in HR was noted. Conclusion:Under the condition of PETCO2 28-30mmHg, 1MAC desflurane anesthesia can be used safely without any increase in ICP in patients undergoing intracranial operations.

Objective To investigate the prognositic factors of small intestine stromal tumors after radical resection.Methods The clinicopathological data of 41 patients with small intestine stromal tumors admitted between January 2005 and December 2010 in Henan Tumor Hospital were analyzed restrospectively.Kaplan-Meier survival rate and COX regression were used to evaluate the prognostic factors.Results There were 22 males and 19 females.The age ranged from 22 to 78 years old (median,55years).Location of tumor included duodenum (n =12),jejunum and ileum (n =29).The 3-year survival rate was 22％ in those 16 cases who reported preoperative gastrointestinal bleeding and 65％ in those without GIT bleeding,the difference was statistically significant (P =0.0012).COX model showed that tumor size,the tumor location,recurrence and metastasis were independent risk factors associated with the prognosis in small intestine stromal patients (P ＜ 0.05).Conclusions The most common clinical presentation of these tumors was gastrointestinal bleeding.The tumor location,recurrence and metastasis and gastrointestinal bleeding was independent risk factors associated with the prognosis of small intestine stromal tumor patients.

Objective To investigate the self-efficacy levels and its influencing factors of community-based patients with chronic obstructive pulmonary diseases (COPD).Methods From October 2008 to March 2009,320 community COPD patients were recruited from a Shanghai community.They undertook questionnaires,scale survey and pulmonary function testing so as to investigate the influencing factors of self-efficacy.Results The total scale of self-efficacy was 74.24 ± 9.50 and the level of selfefficacy in 286 cases( 89.4％ )was intermediate.The knowledge of COPD,social supports,forced expiratory volume at 1 second (FEV1)/forced vital capacity (FVC) and self-management level were entered into regression equation and could explain 57.1％ of the total variance of independent variables.Conclusions The knowledge of COPD,social supports,FEV1/FVC and self-management level are the major influencing factors of self-efficacy in the COPD patients.We should improve the knowledge of disease and strengthen the psychological care and social supports so as to improve their quality of life.
