Objective To investigate the CT manifestations in mesenteric injury.Methods CT imaging data were analyzed retrospectively in 28 patients with mesenteric injury caused by abdominal trauma,of which 26 patients were confirmed by surgery and 2 patients received conservative treatment.Results CT showed simple mesenteric injury in 5 cases,and multiple organ injury in other 23 cases.Only 18 cases were dignosed by preoperative abdominal CT,and the rate of missed diagnosis was 36%.Conclusion Multi-slice CT is an important evaluation method for the detection of acute mesenteric injury.

Objective To investigate hyperhomocysteinemia in chronic renal failure (CRF), its prevalence, etiology and potential relationship to arteriosclerotic events. Methods Plasma total homocysteine (tHcy) was measured in 160 patients with CRF, 31 patients with coronary artery disease and 45 healthy controls by using fluorescence polarization immunoassay. Results Eighty-two percent of CRF patients had hyperhomocysteinemia compared to 22% in patients with coronary artery disease. Mean plasma tHcy level in heomodialysis (HD) patients [(24. 13 ?12. 68) ?mol/L] was significantly higher than that in continuous ambulatory peritoneal dialysis (CAPD) patients [(16. 43?5. 58) ?mol/L] and that in normal controls [(7. 97 ?2. 65)?mol/L] . Plasma tHcy level in dialysis patients with cardiovascular diseases [(27. 12 ?15. 94)?mol/L, n=30] was higher than that in those without clinical manifestation of these complications [(20. 17?8. 71) ?mol/L, n = 62] . The levels of tHcy correlated inversely with Ccr (r = -0. 374, P

Objective To investigate the relationship between hyperhomocysteinemia and cardiovascular structure in maintenance hemodialysis uremia.Methods One hundred and twenty-two patients with maintenance hemodialysis were involved in the study.The level of plasma total homocysteine(tHcy) was determined by fluorescence polarization immunoassay.The morphosis of left artrium was investigated by Doppler echocardiography.Echocardiographic parameters such as interventricular septum thickness(IVST),left ventricular posterior wall thickness(PWTH),left ventricular mass index(LVMI) and left ventricular ejection fraction(EF) were measured.Results The mean level of tHcy in the patients on hemodialysis was(23.52?11.91)?mol/L and the prevalence of hyperhomocysteinemia was 77.0%.The overall prevalence of left ventricular hypertrophy(LVH) was 42.6%.The level of tHcy in the group with LVH was higher than that of the group without LVH(31.75?10.43 vs 15.89?4.15?mol/L)(P

Adenomyomatosis of the gallbladder (GAM) is an acquired,benign proliferative lesion of the gallbladder which is characterized by mucosal proliferation with invaginations and diverticula penetrating into the thickened muscular layer (Rokitansky-Aschoff sinuses).GAM consists of 3 types:diffuse,segmental and fundus GAM.There is no specific presentation of GAM,and computed tomography is helpful for the diagnosis of this disease.From July 2010 to May 2013,16 patients with fundus GAM were admitted to the Second People's Hospital of Wuxi.Rokitansky-Aschoff sinuses and calotte sign at the thickened muscular layer of the fundus of the gallbladder are the typical presentation of the fundus GAM.Enhanced computed tomography examination is of great importance for the diagnosis of the fundus GAM.

Background Trans-arachidonic acids (TAAs) are specific lipid markers of nitrative stress and the major products of NO2·-mediated ismoerization of aracchidonic acid(AA),and they represent a possible new mechanism of NO2·-induced toxicity in ischemic retinopathy.Our previous study demonstrated that high glucose induce nitrative stress response. Objective This study aimed to evaluate the effect of nitrative stress on retinal capillary in diabetic rats by detecting the TAAs with gas chromatography and mass spectrometry(GC/MS).Methods One hundred 2-week-old clean male SD rats were randomly divided into control group and diabetic group.Diabetic rat models were induced by intraperitoneal injection of streptozoticin of 60 mg/kg,and the successful models were identified as the blood glucose level>16.7 mmol/L.The synthesis method was modified in this study andaraehidonic acid w8$utilized as starting material.14E-AA was obtained as a standard sample via expoxidation and deoxidation in a safe and practical pattern.Serum TAAs and AA in diabetic rats were detected by GC/MS in 2,4,8,12 and 16 weeks after injection of streptozoticin.The ratio of peak area of TAAs to AA with selected ion of 79 was estimated and compared with normal rats. Results Fifty rats had been in Diabetic models were established in 50 rats with the successful rate 100%,and the high blood glucose level in model rats retained throughout the experimental duration.GC/MS results showed that the 14E-AA was obtained with the purity of 97.3%,which provided a standard sample to nitrative stress-related research as a premise. No significant differences were found in serum TAAs/AA values at 2 weeks and 4 weeks between model group and control group (t =-0. 376, t =-0. 642,P>0. 05). However,serum TAAs/AA values in at 8,12 and 16 weeks after streptozoticin injection were considerably elevated in comparison with those of control group (0. 0832 vs 0. 1042,0. 0910 vs 0. 1568, 0. 1100 vs 0. 1895;t=-36.409,t=-166.714,t=-148.212,P<0. 05). Conclusion Elevation of serum TAAs/AA is associated with diabetic duration,implying that damage of nitrative stress to retinal capillary is a parallel procedure to diabetic course.Establishment of GC/MS detection system offers a new evaluating indicator in the research on microvascular ischemic disease and could be implemented in clinical testing.
