Objective In order to explore the incidence of PTSD and its risk factors after flood. Methods Diagnostic and Statistical Manual of Mental Disorders (Ⅳ Edition) was used to examine and diagnose the victims in flood district. Results The positive rate of PTSD was 30 9%.The results of logistic regression analysis showed that sex(OR=2 32), age (OR=1 83),style of flood (OR=3 71)and dissatisfaction for sustaining (OR=0 84)were risk factors. Conclusions PTSD is a common mental disorder after flood in our country. Preventive measures should be taken to protect population from PTSD in flood district.

Objective To investigate the diagnostic value of CT virtual endoscopy on the small intestine (CTVE)technology for intestinal diseases. Methods Forty-nine cases with suspected small bowel disease were tested by CTVE from December 2010 to February 2014. They also were performed. Results Of 49 patients, operation or electronic endoscopy showed that 9 cases were benign tumors,29 cases with malignant tumors,3 cases with intestinal polyps,4 cases with intestinal inflammation,2 cases with bowel dysfunction and 2 cases with normal intestinal. CTVE test showed that 11 cases were with benign tumors,29 cases with malignant tumors,2 cases with intestinal inflammation,1 case with intestinal polyps,4 cases with intestinal dysfunction and 2 cases with normal small intestine. Better consistency between the two diagnosis was seen(Kappa = 0. 70). The accurate rate of diagnosis was 85. 71%(42 / 49). The correct rate of CTVE diagnosis of space occupying lesions was 90. 24%(37 / 41). The correct rate of non occupied lesions was 50. 00%(3 / 6). Conclusion CTVE technology has the advantages of simple operation,safe,painless,and clinical diagnosis of small bowel disease rate is higher especially for small bowel accounted disease. It is worthy of clinical application.

Objective To explore the correlation between the enhancement pattern of hepatocellular carcinoma (HCC) on contrast-enhanced ultrasound (CEUS) and its tumor differentiation on histopathology. Methods HCC lesions (n=259) from 224 patients were retrospectively evaluated with CEUS and histopathological examination. CEUS was performed with SonoVue. The characteristics of blood perfusion and parameters of the time-intensity curve (TIC) were analyzed by ACQ soft?ware. Histopathological diagnoses were decided base on Edmonson grading system. Results Pathologic grading of HCC was not related to the arrival time(P>0.05);The washing-out time point and the enhancement time point and peak time point all appeared earlier in poorly differentiated HCC group, than those in moderately differentiated HCC group than those in well differentiated HCC group(P<0.01);The enhancement time point and the expurgation time point are shorter in poorly differ?entiated HCC group than those in moderately differentiated HCC group than those in well differentiated HCC group. All dif?ferences were with statistical significance. The mode of arterial perfusion in early stage was divided into 3 types:spider web type, radiative type and mixed type. The well differentiated HCC group mainly presented as radiative type ( 28/49, 47.14%). But the most of poorly differentiated HCC group mainly present as spider web type(88/127, 69.29%). The mix type was more common in moderately differentiated HCC group(49/83, 59.03%). Conclusion CEUS show different features of TIC pa?rameters and blood perfusion in different pathological stages of HCC lesions so it can serve as a method to assess the biologi?cal behavior of hepatocellular carcinoma.

PurposeTo explore the value of gemstone spectral imaging (GSI) in diagnosis of thyroid nodule hemorrhage.Materials and Methods Seventeen patients with surgery and pathology confirmed thyroid nodule hemorrhage underwent thyroid spectrum CT scan. The CT value, iodine concentration value, water concentration value and the effective atomic ordinal value as well as spectral curve slope of hemorrhagic nodules and surrounding normal thyroid tissue were measured respectively.Results Hemorrhagic thyroid nodules showed equal or high CT value, low concentration of iodine, high concentration of water, low spectral curve slope, and low effective atomic ordinal value on spectral CT imaging. There were statistically significant differences in concentration of iodine value, concentration of water value, and spectral curve slope between hemorrhagic nodules and surrounding normal thyroid tissue (Z=-5.438,-4.679 and-5.317,P<0.01), and there were statistically significant differences in CT value and effective atomic ordinal value (Z=-2.097 and-2.230,P<0.05).Conclusion Energy spectrum CT scan is important in detection and accurate diagnosis of thyroid nodule hemorrhage.

It is very necessary to apply case-teaching method to Emergency Medicine in Universities of TCM. To establish the case-teaching system,we ourselves have written teaching materials,trained teachers, and designed all sorts of the medical records. Moreover, we have deployed other methods and principles to put this teaching into practice, used clinical skill practising as a essential supplement of teaching effect. Comparing with the traditional teaching method, it is clear that case-teaching method could make students' learning initiative and positivity improved significantly, their test scores promoted obviously. Thus, carrying out case-teaching method in Emergency Medicine could advance students capability of acquisition of knowledge and their clinical thinking .

Neuroglobin is a newly discovered member of globulin family.It has neuronprotec- tive effect under the hypoxic and ischemic conditions.In order to make the acting mechanism of globulin clear,many theories have been raised,and corresponding experiments have been done. This article reviews the latest advances systematically in this field,and puts forward possible research directions in the future.

Objective]To evaluate the value of three-dimensional transesophageal echocardiography(3D-TEE)in the applica?tion of percutaneous left atrial appendage occlusionin patients with atrial fibrillation.[Methods]7 patients with atrial fibrillation in Da?lian area(female 4,male 3,mean age 71.5 ± 3.3 years)were enrolled in the study.The maximum and minimum diameter and the max?imum depth ofleft atrial appendage were measured by 3D-TEE,and export morphology and leaf number were viewed.WATCHMAN occlude size was selectedby 3D-TEE. The process of operation was monitored by 3D-TEE. 3D-TEE was also performed in 3 months after the transcatheter closure.[Results]7 patients were performed the transcatheter closure therapy successfully. Preoperative 3D-TEE showed left atrial appendage export:5 cases were oval,and 2 cases were nearly circular. The leaf number was 1.6 ± 0.8. The maximum diameter of the left atrial appendage export was(23.1 ± 1.7)mm,(19.2 ± 2.1)mm minimum diameter,maximum depth of(27.6 ± 3.3)mm. The maximum diameter had good correlation with the size of occluder(r=0.944,P=0.001). 3D-TEE was used for guidance in the transcatheter therapy and succeeded. There were 1 case with little shunt after the transcatheter closure. 3 months af?ter the treatment ,position and shape of the occluderswere all in good.[Conclusion]3D-TEE has the great value in the percutaneous closure of left atrial appendage.

Objective To investigate the effect of hyperbaric oxygen therapy on T-lymphocyte subpopulations in rats with acute pancreatitis. Methods 56 rats were randomly divided into three groups the sham group ( n = 8 ),control group( n = 24) and hyperbaric oxygen therapy group( treatment group, n = 24), then the control group and treatment groups were divided into three subgroups of 8 rats each undergoing euthanasia on days 1,3,7 after the acute pancreatitis induction. The CD4+ ,CD8+ subpopulations of T-lymphocytes in peripheral blood were detected respectively at the fist day and each day of the euthanasia. The sham group was used to make sure that the model was successfully induced. After euthanasia the pancrea was examined using electron microscopy. Results In the control group, the CD4+ cells in AP rats was significantly decreased and the ratio of CD4+/CD8+ also decreased. After 7days of HBO therapy,compared with the control group, the CD4+ lymphocytes of peripheral blood in the treatment group markedly increased( P ＜0.01 ). The CD8+ lymphocytes also increased to a certain extent. And the CD4+/CD8+ ratio of peripheral blood was obviously increased(P ＜0. 01 ). Also more severe pathological changes appeared in the untreated group than in the treatment group. Conclusion Hyperbaric oxygen therapy could improve the oxygen supply in acute panereatitis, regulate T cell immune function.
