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.

Aphasia is an important cause of declining the living level, and the diagnosis and rehabilitation of aphasia depends on knowledge about the structure of brain and the process of language cognitive. The authors reviewed some correlative factors of recovery from aphasia, language areas recombine after stroke and the criterion of judgement prognosis, and tried to offer some theory guidance to aphasia patient for their rehabilitation.

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.

Objective To investigate the anti-tumor effects of hydroxycamptothecin ( HCPT ) with different lactone ratios on the mice models of H22 hepatoma. Methods Mice models of H22 hepatoma were established. Tumor inhibiting rates of HCPT with different lactone ratios ( 0%, 25%, 50%, 75%, 100%) and the growth status of model mice before and after chemotherapy were observed. Serum biochemical indices were determined to investigate the effects of HCPT with different lactone ratios on hepatic and renal function of the mice. Results Positive control drug and HCPT with different lactone ratios all inhibited the tumor in mice with H22 hepatoma, the inhibition rate was 65. 30%, 12. 57%, 49. 23%, 75. 47%, 90. 06% and 93. 22%, respectively. Compared with the model control group, the living conditions of the mice in HCPT groups were improved. With increasing of lactone ratios, the hepatic injury was alleviated markedly, but the renal injury was aggravated. Conclusion There is a positive correlation between lactone ratios and its anti-tumor effect, and HCPT with 75% lactone can achieve preferable anti-tumor effect with less toxicity as compared with that with 100% lactone ratio.

Objective To assess the effect and influencing factors on 131I treatment for cervical lymph node metastasis (LNM) after operation in patients with PTC.Methods PTC patients (n =117;45 males,72 females;average age (45.17± 15.50) years) with postoperative cervical LNM from January 2010 to December 2014 were analyzed retrospectively.LNM was diagnosed by surgical pathology,imaging results and clinical follow-up.Single factor analysis was performed in age,gender,operation mode,TNM stage,131I treatment time and other factors.The results for 131I treatment effect included CR,PR,NC.Two-sample t test and x2 test were used.Results Among the 117 PTC patients with postoperative LNM,53 (45.3％) cases had non-131 I-avid metastasis.Fifty of the 64 (54.7％) patients with 131I-avid metastasis were treated with 131I.Nineteen patients (38.0％) achieved CR,22 (44.0％) achieved PR,and 9 (18.0％) showed invalid results.Fourteen of the 64 patients underwent another cervical lymph node dissection.Nine patients achieved CR,5 patients achieved PR,and 4 PR patients were then treated with 131I and finally achieved CR.Single factor analysis showed that the influencing factors of non-131I-avid lymph node included patients' age (t =3.459),serum Tg level (x2 =6.698) and metastasis with 1s F-FDG uptake (x2 =26.928;all P＜0.05).The influencing factors of 131I treatment effect included lymph node dissection procedure (x2 =6.487),unilateral or bilateral lesion (x2=5.187) and LNM size (x2=8.099;all P＜0.05).Conclusions 131I treatment is ineffective for nearly 50％ of patients with non-131I-avid LNM.The influencing factors of 131I treatment effect include the lymph node dissection procedure,unilateral or bilateral lesions and LNM size.

The degree of satisfaction of the curriculum is related not only to the degree of the curriculum but also to the degree of the students' development. With the concept of teaching reform micro system engineering, using the SIMPP analysis of the degree of satisfaction of the curriculum, the relevant factors of the students are studied. The results show that, the learning state, learning objec-tives, and the education level of mother affect the students more easily on the curriculum satisfaction. Research shows, in the present curriculum condition, educators should guide the students to study hard, establish a clear and reasonable learning goal, give the students the introduction and analysis of the curriculum, can effectively improve the students on the curriculum satisfaction, enhance the enthusiasm of the study.

The influence extent of students from teachers is related to the teaching effect , which means whether it can successfully promote the study of students and reach the expected teach-ing goal during the teaching process. To have a good teaching effect, guided by the micro-system en-gineering of teaching reform, we used SIMPP to analyze the related factors of the influence of students extent from teachers during the teaching process in TCM colleges and universities. The result shows that the influence extent from teachers is related to not only teachers themselves but students and their self-condition and family backgrounds as well. Going further in researching these factors and the related behavior patterns of influence extent of students from teachers is helpful to making the teach-ing more effective and more targeted.

Objective To explore the value of multislice spiral computed tomography ( MSCT ) in predicting the resectability of pancreatic cancer ( PC) .Methods The MSCT images of 102 PC patients ( 62 men, mean age, 61 ±9 years;40 women, mean age, 60 ±9 years) confirmed by postoperative pathology were analyzed retrospectively .The images were analyzed and evaluated by 2 senior radiologists who were double blinded.The relationship between tumor and vessels was investigated based on consensus statement on the radiological diagnosis of PC of the Society of Abdominal Radiology and the American Pancreatic Association in 2014 .The diagnostic criterion on the resectability of PC was based on the 2015 NCCN Clinical Practice Guidelines on PC . Image analysis included the lesion location , size and density , the characteristics of pancreatic and bile ducts , relationship of tumor and adjacent vessels , the extrapancreatic findings as well as T staging and resectability.Results The locations of PC were found in the pancreatic head (n=71,69.6%), body (n=23, 22.5%) and tail (n=8, 7.8%).The long-and short-axis diameter were (28.9 ±8.8)mm and (23.8 ±8.0)mm in head, and respectively, (31.2 ±11.0)mm and (23.8 ±6.3)mm in body and tail, respectively.The imaging findings included hypo-(n=98, 96.1%) and iso-density masses (n=4, 3.9%) on pancreatic phase, intra-and extrahepatic bile duct dilation (n=63, 61.8%), main pancreatic duct cut-off with dilation (n=46, 45.1%), the pseudocyst (n=4), acute pancreatitis (n=1) and chronic pancreatitis (n=2).T staging evaluation by MSCT observed T1 (n=3), T2 (n=7), T3 (n=78) and T4 (n=14), respectively.MSCT assessment for T staging was correct in 98 (96.1%), but wrong in 4 (3.9%), which was quite consistent with pathological T staging (K=0.88, P<0.05).MSCT assessment for the resectability was correct in 98 (96.1%), but wrong in 4 (3.9%).Sensitivity, specificity, positive and negative predictive values, and area under curve of MSCT in the assessment of the resectability were 96.8%, 87.5%, 98.9%, 70.0%and 92.2%, respectively.Conclusions MSCT could improve the diagnostic accuracy for T Staging and resectability of PC .
