Humanities education in military medical university must have military feature in mind.According to special military demand, this education should combine teaching with military historical tradition, historical task, construction of curricula set-up system, and the reality of military campus culture construction to make this education have pertinence.

Objective In this study,we aimed at investigating the clinical,laboratory and management characteristics of adolescent-onset SLE patients compared with adult-onset SLE patients.Methods 470 fe- male patients with SLE were divided into two subgroups:adolescent-onset SLE patients and adult-onset SLE patients.The analyzed variables included clinical,laboratory parameters,damage index and outcome charac- teristics.Results In 470 female patients with SLE,there were 98(20.85%)adolescent-onset SLE patients. The following manifestations occurred more frequently in adolescent-onset SLE patients:malar rash,cutaneous vasculitis,proteinuria and abnormal liver function.Adolescent-onset SLE patients had more severe disease features and had significantly higher mean value of SLEDAI.Mortality was higher in adolescent-onset SLE pa- tients than aduh-onset SLE patients.Renal and blood system were the organs that most frequently involved. Conclusion Adolescent-onset SLE patients accounts for roughly 20.85% of all SLE cases.It is necessary to pay more attention to adolescent-onset SLE patients because the management for them is usually more difficult and the prognosis is usually poorer than aduh-onset SLE patients.

To foster the medical scientific and humanistic spirit of medical students,a cours "eOutline of medical humanities" was designed and implemented in the Third Military Medi-cal University.

Background Deficiency of neurotrophic factor is associated with the damage of optic nerve in glaucoma.Reaserches showed that ectopically applied neurotrophic factor has a transient neuroprotective effect in glaucoma model,and the viral expression of adeno-associated neurotrophie factor may provide long-term supplementation of neurotrophic factor and neuroprotection in tissues.Objective The present study Was to investigate the neuroproteetive effect of adeno-associated viral(AAV)-mediated brain-derived neurotrophic factor (BDNF)on retinal ganglion cells(RGCs)in DBA/2J mice with experimental glaucoma. Methods 10 clean DBA/2J mice were administered intravitreal injection with 1 microliter of AAV-BDNF-GFP in the left eyes at the age of 6 months,and the right eyes were injected with the same volume of saline solution as control.Intraocular pressure (IOP)was measured with Tonolab in the mice every month.Retinas were obtained after 3 months for the investigation of GFP expression in RGCs using fluorescence microscopy.Immunohistochemistry Was performed by applying TUJ1 and Cy3 antibodies to identify surviving RGCs. Results The IOP of DBA/2J mice were 11.90 mmHg and 11.40 mmHg in the right eyes and left eyes,respectively,at 4 months.The IOP of DBA/2J mice began to rise at 5 months and reached its peak in 8 month-old mice.There was no statistically significant difference in IOPs between the right eyes and the left eyes from 4 month-through 9 month-old mice(t=-1.78-0.61,P=0.11-0.90).Three months after intrlavitreal injection of AAV-BDNF-GFP,GFP was positively expressed in RGCs of retinas with the expression rate of 46.33%±8.08%.The over-expression of BDNF led to more RGCs survival than the control eyes (3168.13±1319.33/mm2 vs 2024.81±796.38/mm2,t=2.75,P=0.02). Conclusion These data suggest that BDNF can exert a protective effect in DBA/2J glaucoma mice.

Objective To explore the three criteria of Ranson,CT severity index (CTSI) and the bedside index of severity in acute pancreatitis (BISAP) in assessment of severity and prognosis of acute pancreatitis.Methods A total of 503 diagnosed acute pancreatitis patients from January 2008 to April 2011 were studied retrospectively,including 356 mild acute pancreatitis (MAP) cases and 147 severe acute pancreatitis (SAP) cases.The differences of the three criteria of Rason,CTSI and BISAP in assessment of severity and prognosis of acute pancreatitis were compared with receiver operating characteristic (ROC) curve.The SAP group was divided into no organ failure group and organ failure group,and the predictive value of the three criteria in acute pancreatitis with organ failure was compared.Results There was significant differences between MAP group and SAP group with Rason,CTSI and BISAP score (x2 =236.88、126.24 and 101.27,P＜0.01).The sensitivity (97.3％) and AUC value (0.93) of Ranson criterion was highest.In no organ failure group and organ failure group of 147 SAP patients,there was significant difference between Ranson criterion and BISAP criterion (x2 =17.67 and 26.12,P＜0.01),both sensitivity were 100％,the specificity were 96％ and 85％ respectively,and the area under ROC curve (AUC) value of BISAP criterion (0.8) was the highest.In illness improved group and deteriorated group,the difference of score between Ranson criterion and BISAP criterion was significant (x2 ＝ 9.53 and 10.19,P＜0.05),and the AUC value of BISAP criterion (0.74) was the highest.Conclusions All three criteria can be used to determine the severity of acute pancreatitis.In predicting the risk of SAP with organ failure and prognosis,BISAP criterion is better than Ranson criterion.BISAP criterion is simple and easy to practice,which provides an important rule for evaluating the clinical condition of acute pancreatitis.

BACKGROUNDConventional computed tomography angiography (CTA) is time consuming, user-dependent and has poor image quality in skull base region. This study assessed the feasibility of a new method, dual energy CTA for depicting the cerebral artery.

METHODSPhantom scan was done with head CTA sequences on dual source CT and 64 spiral CT for radiation dose calculation. Dual energy CTA was done with dual source CT on 36 patients who were suspected of having cerebral vascular disease. Three series axial images in 0.75 mm thick, 0.4 mm increment were acquired, which were named with 80 kV, 140 kV and merged images; 80 kV and 140 kV images were transferred into dual energy software, and maximum intensity projection (MIP) image was generated quickly by dual energy bone remove (DEBR group); merged images were transferred into In Space software to acquire MIP image through manual conventional bone remove (CoBR group). Post processing time and reading time were compared. Image qualities of the two groups were compared, mainly focusing on skull base segments of internal carotid artery and bone subtraction. ANOVA and SNK tests were applied for radiation dose comparison. Student's t test and Wilcoxon rank sum test were applied for assessing differences between data for significance. Cohen's kappa was used for interobserver agreement.

RESULTSRadiation dose of phantom scan showed dual energy CTA was between digital bone subtraction and conventional CTA. The post processing time and reading time were much shorter in DEBR than CoBR, and image quality in skull base was much higher in DEBR than CoBR (P < 0.01). There was no significant difference for suprasellar vessels between two groups (P > 0.5). Interobserver agreement for all vessel segments was excellent (kappa = 0.97).

CONCLUSIONSDual energy CTA is a reliable, new modality for depicting cerebral artery, overcoming the limitation of conventional CTA in the skull base region. It can save much time in post processing and reading than conventional CTA.

Helminth infection can lead to organic,digestive and other tissue's pathological damage.Helminth diseases are harmful to human and animal health,and can cause reproductive failure,inhibits the growth and development of juvenile ani-mals,even lead to death of humans and animals in serious cases,and poses significant impacts on public health and causes eco-nomic losses to the animal husbandry.Currently,the prevention and control of helminth disease is largely dependent on inte-grated control measures including the use of drugs.Due to drug residues,drug resistance,and other issues,the development of new drugs and vaccines is imminent.So far,there is few ideal vaccines to control helminth diseases,which is due to that hel-minths have evolved mechanisms to evade host immune attacks during evolution,such as immune isolation,antigen variation, molecular simulation and so on.Therefore,this review describes the recent research advances in the immune evasion strategies of parasitic helminth,which aims to provide a reference for the development of new vaccines or drugs for better prevention and control of helminth diseases.
