Because of lots of ethical problems,military medical triage has been unaccepted by general doctors.But it's adopted by American Army in front of facts of the war.The main principles of the military medical triage are justice and efficiency.They practice the military medical triage through tow steps.First,all patients are assigned into urgent,immediate ,delayed,minimal or ambulatory and expectant status in decreasing order of medical urgency.Second,choosing the model of triage depends on nonaustere,austere or extreme conditions.The ethical issues of American military medical triage focus on four aspects - how to deal with minimally injured patient treatment first,how to treat expectants,how to care for noncombatant casualties and who decide the model of triage.

OBJECTIVE:To determine the concentration of pseudoephedrine hydrochloride in human plasma by LC/MS. METHODS:The separation of sample was performed on Zorbax Eclipse XDB C18 with diphenhydramine used as the internal standard.The mobile phase was a mixture of methanol-water(10mmol?L-1 NH4Ac plus 0.1% acetic acid)(55∶45) with a flow rate of 0.2mL?min-1.The column temperature was set at 30℃.The atmospheric pressure chemical ionization-mass spectrometry(APCI-MS) were adopted with pseudoephedrine m/z =166.1 and diphenhydramine m/z =242.3.RESULTS:The linear concentration range for pseudoephedrine was 3.2～408.96ng?mL-1(r=0.999 0) with lowest detection limit at 3.2ng?mL-1.The average recovery was 98.21% with both the intra-day RSD and the inter-day RSD at less than 13%.The stability of pseudoephedrine was stable.CONCLUSION:The method is of high sensibility and accuracy,and it can be used for blood concentration monitoring pharmacokinetic study of pseudoephedrine.

Objective To analyze diagnostic experience of children with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and assess its surgical results.Methods Six children with ALCAPA had been diagnosed in our hospital from Mar. 2006 to Oct.2007 aged from 6 months to 10 years old(median 43.5 months).The medical data included common clinical presentations,the findings of electrocardiogram(ECG),the echocardiogram,ECG-gated 64-slice computed tomography,the digital subtraction angiogram (DSA),surgical records and the outcome.Results Diaphoresis,fantod,breathlessness and difficult feeding were commonly presented in 5 cases ALCAPA and the 5 children presented with left ventricular failure in infancy.The predominant ECG findings were Q waves and ST segment changes in the anterolateral chest leads in 4 cases,ST changes in 1 case,and normal ECG in 1 case.Cross-sectional echocardiography showed dilated left ventricles with poor contractility in 4 cases,medium mitral regurgitation in 2 cases and severe mitral regurgitation in 2 cases,aneurysmal dilatation of the right coronary artery(RCA) in 2 cases.CT and DSA examinations showed characteristic changes in these children.The surgical reestablishment of a two-coronary system was performed in 5 cases,direct reimplantation in 2 cases and creation of an autologous extrapulmonary tunnel in 3 cases.Simultaneous mitral annuloplasty was performed in 2 cases.After operation,the symptoms of 5 cases were all improved and none died.Conclusions Understanding the clinical manifestations and lab findings of ALCAPA is helpful to making an early diagnosis of ALCAPA.Early surgical treatment can improve the patients′ outcome.

Objective To find out the incidence tendency and characteristics of bladder tumors during the past 28 yesrs in our institution. Methods The data from 1980 to 2007 were divided into three stages:1980-1989,1990-1999和2000-2007.Microsoft excel and SPSSl3.O were used to analyze the sex,age and histological types. Results There were 2350 cases of bladder tumors in 28 years.There were 92(66 males,26 females)cases of benign tumors and 2258(1788 males,470 females)malignant tumors,the incidence in male was 3.8 times higher than that in female.The cases of bladder malignant tumors increased,and the female increased faster than male.The peak age of incidence changed from 50-69 in 1980-1989 to 60-79 in 2000-2007.The average age of squamous cell carcinomas was 68 years,which was the oldest;and the average of paraganglioma was 35,which was the youngest.The age of urinary bladder carcinoma in 1980-1989,1990-1999 and 2000-2007 were significantly different(male:57.5±11. 7,62.6±12.3,65.9±11.3;female:58.7±13.6,60.75±12.1,65.85±12.0,respectively,P<0.05).In male,the age of squamous cell carcinomas was significantly different from the age of urothelial cell carcinomas and adenocarnomas(68.0±9.7 vs 59.85±14.1 and 63.4±9.9,respectively,P<0.05).Inverted papillomas were the most common bladder benign tumors;urothelial cell carcinomas were the most common bladder malignant tumors,and adenocarcinomas were the second,squamous cell carcinomas were the third. Conclusion The incidence of bladder malignant carcinomas in our institution increased and the female increased more quickly than male.

Purpose To investigate the correlation between BRAF V600E mutation and clinicopathologic parameters in bilateral welldifferentiated thyroid carcinoma.Method Collected 80 patients with papillary thyoid carcinoma (PTC) (67 patients with classical type,8 patients with follicular variant,3 patients with oncocytic variant,2 patients with tall cell variant),5 patients with follicular carcinoma and 30 normal tissues near the tumor,BRAF V600E mutation was detected via polymerase chain reaction.Result The presence of BRAF V600E mutation was found in 52 patients with PTC (65.0％),the mutation was not in the 5 patients with ollicular carcinoma as well as in the 30 normal tissues near the tumor.The BRAF V600E mutation was positively correlated with age,capsule invasion,lymph node metastasis,tumor clinical stage.In the histological variant of PTC,the BRAF V600E mutation rate of classical type and tall cell variant is very high (70.1％,100.0％),but the BRAF V600E mutation rate of follicular variant is very low (33.3％).Conclusion The BRAF V600E mutation rates are different in different age groups.The BRAF V600E mutation was positively correlated with capsule invasion,lymph node metastasis,tumor clinical stage.The BRAF V600E mutation rate of classical type and tall cell variant is very higher than follicular variant.

[Objective]To analyze the clinical features and related risk factors in diabetic retinopathy(DR)and diabetic periph?eral neuropathy(DPN),the two micro-peripheral vascular diseases in newly diagnosed type 2 diabetes mellitus.[Methods]A retro?spective study of 211 cases of newly diagnosed type 2 diabetes mellitus inpatient from 2009 to 2012 ,and compare the two micro-peripheral vascular complications.[Results]The morbidity of DPN was(33.6%),which was higher than that of DR,some cases of DR co-existed with DPN,DR was related with DPN(r=0.158,P=0.020). Age and systolic blood pressure were the common risk factors in DR and DPN by single factor analysis.[Conclusion]It should be paid attention to the screening of both DR and DPN in each age group in newly diagnosed type 2 diabetes mellitus. Except for the control of blood glucose ,the control of the systolic blood pressure is important in the prevention and treatment in the two micro-peripheral vascular diseases.
