Objective　To investigate the effective application of trauma score methods and decrease the errors of evaluation.　Methods　The injury severity of 1 855 patients, including 583 outpatients, 907 inpatients, and 365 ICU patients, evaluated with various common-used trauma score methods was analyzed comparatively. 　Results　The area under the receiver operating characteristics curves (AUC) of different trauma scoring methods were 0.81-0.91. Specificity, sensitivity, and accuracy were above 78%. Excessiveness of scale in severity and undertriage were found for physiological indexes; whereas insufficiency of scale in severity and overtriage for anatomic indexes. The errors may happen if the prognosis of trauma patients merely rely on physiological, anatomy or age parameters. 　Conclusions　The use of different trauma score methods should be in combination with individual conditions and specific injury.

OBJECTIVE:Using the result of pharmacoeconomic evaluation to instruct the management of drug prices.ME_ THODS:Establishing a reference price and combining economic benefit to decide the price of a drug.RESULTS&CONCLU_ SION:According to the rational value scope,the prices of new drugs can be fixed.A reasonable and timely adjustment of the price can be made.

Objective To investigate the features of multiple pelvic injuries (fracture combined with multiple traumas) and their effects on management and prognosis. Methods A total of 233 cases of hemodynamically unstable pelvic fractures were grouped according to the patterns of violence, fracture and associated injuries. They were assessed with measured indexes in physiological state, anatomic injury and blood requirement. Their possibilities of survival (Ps) were also predicted. All the data were statistically analyzed. Results The pelvic fractures were often combined with multiple traumas and frequently resulted from high energy traffic accidents. The correlations among sources of bleeding, amounts of blood loss and hemodynamical changes were disproportional. In unstable pelvic fractures with extra pelvic bleeding, BP and blood requirement were significantly different, and their AIS and ISS of the pelvis were higher and their Ps was lower than in the other groups. Conclusions Multiple pelvic injuries caused by high energy are often highly risky and combined with multiple traumas and several sources of bleeding. A clear and precise assessment of the total injuries and sources of bleeding will help treat the patients with different managements.

Objective To investigate the specific humoral immunity and the therapeutic effect of nasal tolerance with a dual analogue (Lys262-Ala207) in the patients with myasthenia gravis (MG). Methods The levels of serum anti-AChR IgG and anti-AChR IgG isotype were determined with ABC-ELISA in 39 MG patients before and after treatment with Lys262-Ala207 and also in controls. cAMP was measured at the same time. The clinical severity and prognosis of MG were evaluated with Xu′s clinical scoring system. Results There was different in total IgG content among all groups. However the IgG 2 content was lower after the treatment and that of control (P

Objective To investigate the clinical effect of Exelon and the high pressure oxygen uniting to treat the old-age period of dementia and influence of Exelon on plasma transforming growth factor ?(TGF-?), insulin-like growth factor 1(IGF-1)and intercellular adhesion molecule-1(ICAM-1) in patients with elderly dementia.Methods 172 cases with ?lzheimer's diseases (AD) and 202 cases with vascular dementia (VD) were randomly divided into Exelon group, high pressure oxygen group, uniting group (taking Exelon and doing the high pressure oxygen together) and piracetam group. The MMSE scores were graded before and after treatment. TGF-?, IGF-1 and ICAM-1 were detected in Exelon group before and after treatment.Results MMSE scores had improved in Exelon group, high pressure oxygen group and uniting group after the treatment in AD group and VD group (all P

Objective To demonstrate the moderate hypothermia's effect to acute cerebrovascular disease.Methods 82 prospective patients with acute cerebrovascular disease treated by moderate hypothermia were evaluated.According to the standard of clinical neurologic deficiency ,we contrasted the clinical and laboratory effect of control before moderate hypothermia and after moderate hypothermia. Results The neurologic function and SOD improved obviously; NO,ICAM-1,IL-1 and temperature decreased after moderate hypothermic therapy;patients'survival rate and recovery rate improved obviously too.The best therapy time was within 2h after acute cerebrevascular disease happened. Conclusions Moderate hypothermia can improve heal rate of brain damage and decrease mortality and disable rate.

Objective To make the scale for the compliance of patients with chronic obstructive pulmonary disease (COPD) during home oxygen therapy.Methods By literature searching,semi-structured interview,expert consultation,as well as pre test,the tentative scale was formed at first.Then the investigation was conducted among 324 patients with COPD selected.Finally the scale was formed by testing the reliability and validity.Results The scale was made up of two dimensions with 16 items in total.It showed that Cronbach α coefficient was 0.984,split-half reliability was 0.976,and content validity index was 0.98.The exploratory factor analysis combined with AMOS 7.0 confirmatory factor analysis was used for construct validity of the home oxygen therapy compliance scale.Conclusions The self-management behavior scale for patients with COPD shows good reliability and validity,which can be used to evaluate the compliance during home oxygen therapy and provide reference tool for COPD patients' family intervention.

Objective To observe the clinical efficacy of acupoint thread-embedding in treating premature ovarian failure.Method By following the visiting or admission sequence, 35 patients were randomized into a treatment group (acupoint thread-embedding group) and a control group (Western medication group). The therapeutic efficacy, and the levels of follicle stimulation hormone (FSH), luteinizing hormone (LH) and estradiol (E2) before and after the treatment were observed.Result After the treatment, the recovery rate and total effective rate were respectively 44.4% and 72.2% in the treatment group, significantly different from 0.0% and 52.9% in the control group (P<0.05). The level of serum E2increased significantly in both groups after the treatment (P<0.01); the serum FSH dropped significantly in both groups with a more significant efficacy in the treatment group, and the change after the treatment was extremely statistically significant in the treatment group (P<0.01) and the change after the treatment in the control group was statistically significant (P<0.05); after the treatment, the serum LH presented a tendency to decline but without a statistical significance (P>0.05).Conclusion Acupoint thread-embedding can produce a satisfactory efficacy in treating premature ovarian failure.

OBJECTIVE Discuss the cooperative relationship between The Office of Nosocomial Infection Control("the Office") and the Center for Disease Control and Prevention("the Center") in hospital.METHODS The cooperative relationship between the Office of Nosocomial Infection Control and the Center were analyzed,the third degree A Class hospitals in Beijing area.RESULTS 25 hospitals had set up Centers.Among them,there are special stuff in charge of the report of the infection in 17 hospitals which had the Office with the function of the Center.So far,none of the Offices with the function of the Center can operate all the functions of the office.CONCLUSIONS The setup of the Center is to detect and control infectious disease on the basis of nosocomial infection control.
