In the face of both market competition and health logistic support,whether military hospitals can adapt their operation and management strategies to balance the relationship of battlefield and market place,is the lifeline of their survival and development.The study summarized significance of strategic management of the hospitals in view of characteristics of such hospitals,and introduced explorations made at the hospital in their strategic management.

Objective To evaluate the diagnostic value of myeloperoxidase (MPO)in diagnosis of non-ST elevation acute cor-onary syndromes (NSTE ACS).Methods The MPO was determined in 61 unstable angina pectoris (UAP)patients and 54 non-ST-elevation myocardial infarction (NSTE MI)patients,then analyzed the data with receiver operationg characteristic curve (ROC curve)statistical software.The major adverse cardiac events (MACE)were obseved in 106 NSTE ACS patients through 1 year of follow-up.Results The MPO values of NSTE MI group and UAP group were 672±418 ng/ml and 459± 328 ng/ml,the difference was statistically significant (t=3.928,P <0.001).The cTnI values were 558±261 pg/ml and 405 ±278 pg/ml of respectively.The difference was statistically significant (t = 3.089,P = 0.003).The area under the ROC curve of MPO was 0.726 when the optimal cutoff value was 382 ng/ml in the diagnosis of NSTE MI.The sensitivity and specificity was 92.6% and 39.8%.The area under the ROC curve of cTnI was 0.799 when the optimal cutoff value was 484 ng/ml in the diagnosis of NSTE MI.The sensitivity and specificity was 65.5% and 92.3%.High MPO maintained a strong association with the risk of major adverse cardiac events through 1 year of follow-up.Conclussion MPO is ahigh sensitivity marker of the NSTE MI and of clinical value for prognosis of NSTE ACS.

Objective To evaluate the prognosis value of heart‐type fatty‐acid binding protein(H‐FABP)and myeloperoxidase (MPO) in non‐ST elevation acute coronary syndromes(NSTE ACS) .Methods 181 NSTE ACS patients were divided into 4 groups according to the level of H‐FABP and MPO ,and the baselines of 4 groups such as gender ,age ,hypertension ,smoking ,body mass in‐dex ,diabetes mellitus ,hyperlipidemia were compared .The incidences of adverse cardiac events in 4 groups were compared after a 2 years′follow‐up .Results By multivariate COX regression adjustment for other risk factors ,the relative risk(RR) of H‐FABP for adverse cardiac events was 2 .023(95% CI:1 .029 -3 .987 ,P=0 .002) ,and MPO was (95% CI:2 .196 -5 .325 ,P< 0 .05) .The 2 years′follow‐up showed the incidence of adverse cardiac events in NSTE ACS patients with higher H‐FABP and MPO levels was higher than the NSTE ACS patients with one or two indicators of normal levels .Conclusion The combined application of H‐FABP and MPO could has clinical significance for the prognosis of patients with NSTE ACS .

Objective To determine whether the candidates who were disqualified for having phoria or tropia in People′s Liberation Army Air Force ( PLAAF) medical selection of flying cadets are qualified or not according to United States Air Force ( USAF) Medical Standards Directory , and to raise suggestions on revising PLAAF medical standards . Methods All the candidates who had participated in the final medical selection of flying cadets were reevaluated and determined as qualified or not according to USAF Medical Standards Directory .Results There was a marked difference between disqualification rates of PLAAF and USAF .13.87%of the candidates who were regerded as disqualified by PLAAF standards were qualified according to USAF Medical Standards Directory .These cadets might be eliminated by mistake . Conclusion The standard on heterophonies of the PLAAF is more stringent than that of the USAF .We shoucd revise PLAAF standards using USAF standards for reference .

Objective:To compare the efficacy of left parapharyngeal pressure (PLP) combined with cricoid pressure in preventing gastric insufflation during positive pressure ventilation by facemask.Methods:Two hundred and forty patients of both sexes, aged 18-75 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, undergoing surgery under general anesthesia requiring endotracheal intubation, were selected and randomly divided into 4 groups ( n=60 each) using a random number table method: cricoid pressure group (group CP), left PLP group (group LP), cricoid pressure combined with left PLP7 group (group CP+ LP), and control group (group C). The gastric antrum cross-sectional area (CSA) was measured by ultrasound in all the patients before induction of anesthesia, and facemask ventilation in pressure-controlled mode with suction pressure of 25 cmH 2O was applied, the patients in 4 groups were treated with different manipulations, and 3 min later the CSA of gastric antrum was measured again.The gastric antrum CSA before and after ventilation and the difference were recorded.The occurrence of gastric insufflation was examined by ultrasound after ventilation. Results:Compared with the baseline before ventilation, the CSA of gastric antrum was increased after ventilation in C, CP and LP groups ( P<0.01), and no significant change was found in the CSA after ventilation in CP+ LP group ( P>0.05). The difference of gastric antrum CSA was decreased in turn in C, CP, LP and CP+ LP groups ( P<0.05 or 0.01). The incidence of gastric insufflation were 53%, 30%, 12% and 0 in C, CP, LP and CP+ LP groups, respectively.Compared with group C, the incidence of gastric insufflation was significantly decreased in LP and CP+ LP groups ( P<0.05), and no significant change was found in group CP ( P>0.05). Compared with group CP, the incidence of gastric insufflation was significantly decreased in group CP+ LP ( P<0.05), and no significant change was found in group LP ( P>0.05). Conclusion:The combination of left PLP and cricoid pressure can effectively prevent gastric insufflation during positive pressure ventilation by facemask.
