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.

This article will address the effects of some kinds of herbs on breast cancer cell proliferation, the mechanism and their biological activity. The review will focus on 3 popular botanical herb: Angelica sinensis (dong quai) , Salvia miltiorrhiza (dan-shen root) and ginseng.

Objective To investigate the risk factor profile of pneumonia caused by pandrug-resistant Acinetobacter baumannii (PDRAB)in intensive care unit for better distinction between PDRAB infection and colonization.Methods The clinical data of 99 patients diagnosed as A.baumannii pneumonia between February 2009 and March 2012 in Fangcun Hospital,a branch of Guangdong Provincial Hospital of Traditional Chinese Medicine,were reviewed and analyzed retrospectively.The risk factors associated with pandrug-resistance in A.baumannii were examined with multivariate logistic regression analysis.Results ICU stay,duration of invasive ventilation,longer duration of treatment with carbapenems,beta-lactam/beta-lactamase inhibitor,or quinolone antibiotics,use of ≥3 classes of antimicrobial agents,≥3 invasive procedures (including indwelling gastric canal, catheterization,central venous catheter,arterial sheath),and fiberoptic bronchoscopic treatment were associated with PDRAB pneumonia (P <0.05).Multivariate logistic regression analysis showed that use of ≥3 classes of antibiotics,fiberoptic bron-choscopic treatment,and longer duration of treatment with beta-lactam/beta-lactamase inhibitor were independent risk factors predicting the emergence of PDRAB pneumonia.Conclusions We should pay more attention to these risk factors in clinical prac-tice for better differentiation between PDRAB infection and colonization so that appropriate control measures can be taken pro-actively.

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.

This study was designed to investigate inhibitory effects and possible mechanisms of snake venom tripeptide (pENW) on platelet adhesion in order to promote the development of a novel anti-platelet therapy. To study the inhibitory effects of pENW on platelet adhesion, washed platelets pre-incubated with pENW (116.5-466.2 μmol x L(-1)) were used to test the ability of platelet adhesion to fibrinogen. Effect of pENW on fibrin clot retraction was also tested. Effect of pENW on platelets viability was tested by MTT assay. Effect of pENW on reactive-oxygen species (ROS) levels of platelet was studied by flow cytometry assay. Calcium mobilization in Fura-2/AM-loaded platelets was monitored with a spectrofluorimeter. Cyclic guanosine monophosphate (cGMP) and cyclic adenosine monophosphate (cAMP), thromboxane A2 (determined as its metabolite thromboxane B2) were measured using enzyme immunoassay kits. Akt, ERK and p38 phosphorylation were tested by Western blot. The results showed that pENW inhibited platelet adhesion and fibrin clot retraction in a concentration-dependent manner without cytotoxicity. Intracellular cGMP and cAMP in both resting and thrombin-activated platelets were increased by pENW. In addition, pENW attenuated intracellular Ca2+ mobilization and TXA2 production in platelets stimulated by thrombin. As shown by Western blot assay, Akt, ERK and p38 phosphorylation in thrombin-induced platelet were attenuated by pENW. However, inhibitory effects of pENW had nothing to do with ROS. Thus, pENW exhibited a significant inhibition on platelet adhesion to fibrinogen, which means pENW could block the first step of thrombosis as while as retard the more stable clot formation. The mechanisms of pENW on inhibition platelet adhesion might be related to instant regulations, such as protein kinases.

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.

AlM: To study the effects of different concentrations of Coix seed oil on human retinal capillary endothelial cells ( HRCECs ) proliferation and vascular endothelial growth factor ( VEGF) expression in high glucose environment.
METHODS: HRCECs extracted from human fresher eyeball and cultured in vitro, and ultimately used in the experiment were the growth of 3rd ~ 4th cells, the experimental were divided into blank control group, low glucose control group, high glucose control group, high glucose + ( 50ü L/mL, 100ü L/mL, 200ü L/mL ) different concentrations Coix seed oil group. Detecting the multiplication of HRCECs by MTT, the immunocytochemical method was employed to detect the each group HRCECs of VEGF expression.
RESULTS:MTT assay results showed that: different concentrations of coix seed oil acted at HRCECs for 48h, inhibition of cell proliferation was significant difference compared with high glucose control group (P<0. 05). Within 48h showed concentration dependence. There was no statistical difference between the low glucose group and high glucose control group (P>0. 05). lmmunocytochemical assay showed that:50ü L/mL, 100ü L/mL, 200ü L/mL Coix seed oil acted at HRCECs 48h, the expression of VEGF decreased significantly compared with the high glucose control group ( P< 0. 05 ), and in a dose- dependent manner. However, in high glucose control group, the expression of VEGF was obvious higher than that of low glucose control group (P<0. 05).
CONCLUSlON:Coix seed oil can inhibit the HRCECs proliferation and suppress the VEGF expression in high glucose environment.
