Objective To explore the levels of serum interleukin-6 and interleukin-18 in newly diagnosed type 2 diabetes mellitus (T2DM) and investigate their roles. Methods The serum interleukin-6 and interleukin-18 levels were detected in 50 newly, diagnosed T2DM patients (T2DM group) and 40 normal subjects (control group). Fasting blood glucose, fasting insulin, blood lipid, body mass index (BMI) and waist/hip ratio (WHR) were measured. HOMA-IR and HOMA-β were calculated. Results The serum interleukin-6 and interleukin-18 levels in T2DM group were significantly higher than those in control group [(2.56 ± 1.09) ng/L vs (1.81±0.80) ng/L, (5.38±0.91) ng/L vs (4.62±0.59)ng/L] (P <0.01).Interleukin-6 level was positively correlated with HbA_1c,while interleukin-18 level was positively correlated with BMI and WHR. Interleukin-6 and interleukin-18 levels were positively correlated. Interleukin-6 and interhukin-18 could predicted the insulin resistance. Conclusion Interleukin-6 and interleukin-18 take part in the development of T2DM, and can be related to the insulin resistance.

Purpose　To improve the diagnostic level of liver and spleen traumatic rupture in CT. Methods　39 cases of liver and spleen traumatic rupture diagnosed with CT images,analyzed comparing with CT findings,surgical outcome and clinical representation. Rusults　There are two categories of CT findings in cases of liver and spleen traumatic rupture. Liver and spleen traumatic avulsion: 7cases represented high density patches in liver and spleen parenchyma; 4cases represented low density zonary focus;18 cases represented irregular low density patches. 11 cases represented multi-spots of high density in above mentioned focuses. Hematoma under envelop of liver and spleen: 15 cases represented same or low density lunular focuses lying the edge of liver and spleen, some fresh hematoma represented high density. Conclusion　For diagnosing the liver and spleen traumatic rupture, following CT findings are valuable: ①Irregular high and low density bleeding focuses in liver and spleen; ②Lunular low density hematoma under envelop of liver; ③ Celiac hematocele symptom.

Objective: To investigate the relationship between postprandial glucose and cardiovascular disease.Methods: Ninety-four patients were divided into an IFG,an IGT and a DM group,and observed for the incidence of cardiovascular disease and the risk indexes of cardiovascular disease,such as CIMT,TC,TG,HDL-C,LDL-C,BMI,SBP,DBP and CRP.The correlation between postprandial glucose and the risk indexes were analyzed. Results: The risk indexes were obviously higher in the IGT and DM groups than in the IFG group(P0.01).Postprandial glucose was correlated positively with the risk indexes,but negatively with HDL-C.Conclusion: Postprandial hyperglycemia increases the incidence of cardiovascular disease.

Insulin resistance is the important base of the pathogenesis of type 2 diabetes.Physical exercise can improve insulin sensitivity.This article presents an overview of how physical exercise improves insulin resistance and helps the prevention and treatment of diabetes mellitus by analyzing its influence on the level of insulin receptor and post-receptor and adipose cell cytokine.

Objective:To evaluate the antioxidant status in IGT and newly diagnosed type 2 diabetes patients, we detected the levels of serum Vitamin E(Vit E), vitamin C(Vit C) and intraerythrocytic glutathion(GSH).Methods:The levels of serum Vit E, Vit C and intraerythrocytic GSH were measured in 32 IGT and 41 newly diagnosed type 2 diabetes patients, and the associated factors with GSH/GSSG (oxidized glutathione) were evaluated.Results:Significant decrease of serum Vit C intraerythrocytic GSH and GSH/GSSG were noted in IGT and newly diagnosed type 2 diabetes patients. There were negative correlation between GSH/GSSG and blood glucose, triglyceride, HbA_(1c) in IGT and newly diagnosed type 2 diabetes patients.Conclusion:The results showed that antioxidant defenses are decreased in IGT and newly diagnosed type 2 diabetes patients. To improve the metabolism of blood glucose and triglyceride may have some beneficial effects on antioxidant defenses in IGT and newly diagnosed type 2 diabetes patients.

Objective To explore baccalaureate nursing students' perception of caring, so as to provide evidence for promoting their caring behaviors. Methods Phenomenology was the chosen methodology, 11 baccalaureate nursing students were interviewed in depth. Results Themes of caring were formed into four categories: caring behavior was reciprocal; the motives of caring included fear, concern, responsibility and obligation; knowledge, technical competency and professional helping relationship constituted caring; the confusions of caring came from many factors in clinical practice. Conclusions Baccalaureate nursing students can understand the connotation of caring accurately. To encourage their caring behaviors,clinical supervisors and managers should take all kinds of measures to maintain their faith in caring.

Objective: To analyze the relationship between meteorological factors and the number of daily heart failure (HF) patients for emergency room (ER) visit at Fengxian district of Shanghai in order to provide the experience for prevention and control of HF morbidity. Methods: Daily number of HF patients treated in ER of our hospital from 2012-01 to 2014-12 with corresponding meteorological, air pollution data at the same period were collected and analyzed by Spearman correlation study and multiple stepwise regression analysis. Results:①The differences of temperature, humidity, air pressure at 24-, 48-hour before and 48-hour after ER visit were positively related to the number of HF patients; the number of HF patients was signiifcantly related to the differences of temperature and air pressure at 48-hour before ER visit,P<0.001.②Multiple stepwise regression analysis showed that the most affecting meteorological factor for ER visit of HF patients was the daily lowest temperature,P<0.05, the second factor was the daily average relative humidity,P<0.05. Conclusion: Radical changes of temperature, relative humidity and air pressure elevated the number of HF patients for ER visit; daily lowest temperature and decreased relative humidity were the important factors for elevating the number of HF patients for ER visit.

Objective To investigate the expression of ?-methylacyl CoA racemase (AMACR,P504S) and p63 in prostate carcinoma tissues and the clinicopathologic significance in the diagnosis of the disease. Methods The expression of AMACR and p63 in 39 cases of prostate carcinoma and 24 cases of benign prostate lesions were examined using immunohistochemical method. The association of the AMACR and p63 expression in prostate carcinoma tissues with the differentiation and clinical staging was evaluated. Results The positive rates of AMACR and p63 were 85%(33/39) and 10%(4/39),respectively,in prostate carcinoma tissues; and those were 21%(5/24) and 88%(21/24),respectively,in benign prostatic hyperplasia. There were significant differences of these values between prostate carcinoma and benign prostatic hyperplasia (P0.05). Conclusions Over-expression of AMACR and under-expression of p63 may be the preliminary incident of the formation of prostate carcinoma,which may induce carcinoma into occurrence and progression.Thus it may be an early diagnostic parameter and a novel target for prostate carcinoma treatment.

Along with the increasing medical image data,it is imperative to set up an effective system about medical image retrieval.Essentially,the image classification is crucial for medical image retrieval.As a distribution pattern of image gray scale,texture is an important character.Wavelet multi-scale decomposition is essentially multi-channel filtering and its multi-resolution analysis structure is identical with human visual system.So the extraction of texture feature under different resolutions after multi-band wavelets transform is of great benefit to image recognition and image retrieval.Consequently,this paper designs an image classification method based on eight-band wavelet.This method solves the key technology in the medical image retrieval,and it gains very high classification rate.

Objective To explore the correlation between imaging features and pathological findings of alveolar soft part sarcoma (ASPS).Methods The clinical data,radiographic images and pathological characteristics of seven patients with histopathologically proved ASPS from 2003 to 2009 were retrospectively reviewed.Digital radiography (DR),plain CT,pre and post-contrast MR and DSA were performed in all patients.HE staining and periodic acid-Schiff (PAS) staining were used in pathological examination and CD34 were marked in immunehistochemical study.Results All patients were females.Their age ranged from 16 to 37 years with median of 24 years.Two tumors were located in pelvics,three were located in thighs,and two were located in legs.DR and CT plain scan features of ASPS were non-specific.MR demonstrated the tumors with large diameter and well defined margin locating in the deep tissues.Tumors were hyperintense on T2-weighted and T1-weighted images with many flow void vessels and persistent remarkable enhancement.There were numerous vessels with arteriovenous fistula on DSA.Pathological examination revealed solid nests of several polygonal tumor cells arranged in an alveolar pattern and separated by thinwalled,sinusoidal vascular channels.Tumor cell were noted on periodic acid-Schiff (PAS) stains.And the endothelial cells of sinusoidal vascular channels were positive on CD34.Conclusions As a malignant tumor which predominantly developed in deep location of trunk or extremities in young females,numerous void signal and hyperintensity on T1-weighted were the features of ASPS on MR.Numerous vessels could also be confirmed on DSA.These image findings were correlated closely with the pathological manifestations.
