China Medical Equipment 2017;14(5):49-51
Objective:To explore the application value of multislice spiral CT scanning on abdomen for the detection of complication of acute pancreatitis.Methods: 120 patients with acute pancreatitis were divided into observation group (70 cases) and control group (50 cases) according to different detection method. The patients of control group were applied basic clinical detections included X-ray radiography and ultrasound imaging, while patients of observation group were supplemented CT detection besides these detections of control group. And situation of complication of patients in two groups were observed.Results: The positive rate of complications, which involved pancreatic pseudocyst, cellulitis, complications of gastrointestinal tract, pancreas hemorrhage and pancreatic ascites, in observation group was 97.14%, that was significant higher than that (62.0%) of control group (x2=24.74,P<0.05). Among 20 patients with pancreatic pseudocysts, there were 9 patients located at tails of pancreases, 6 patients located in bodies of pancreases, 3 patients located in small omental bursas, 2 patients located at heads of pancreases, and the CT images of them showed quasi-circular liquid form density lesions with clear boundaries appeared in lesion field. The CT images of cellulitis showed the volume of pancreas increased and the boundaries were fuzzy, and a larger range of density lesions with irregular soft tissue shape appeared in its periphery. CT detetions of gastrointestinal complications showed fuzzy point-shaped, strip-shaped and flake-shaped soft tissue-styled density shadow appeared in gastrointestinal tracts. The CT image of pancreatic ascites showed intraperitoneal fluid density shadow.Conclusion: Abdominal CT scan applied on patients with acute pancreatitis can increase the positive rate of complications and may be used as preferred detection method for clinical evaluation on the complications of acute pancreatitis.

The value of combined application of both ECG-gated cine MRA and 3D-CEMRA in the detection of large intracranial aneurysms was evaluated and the findings were compared with those of conventional MRA and DSA. Twenty-four patients with 26 large intracranial aneurysms underwent MRI and DSA. All these aneurysms, diameter from 15 to 39 mm, were located at internal cerebral artery (n=12), vertebral artery (n=3), basilar artery (n=4), anterior cerebral artery (n=2), middle cerebral artery (n=2), anterior communicate artery (n=2) and posterior communicate artery (n=1). Thirteen cases of hematoma or cavernoma were studied as control group. All patients were examined on GE 1.5T MR system. ECG-gated cine MRA was performed with 2D multi-phase fast gradient-recalled echo sequence in a single section. All the images were analyzed with signal intensity VS time curve for differentiating intraaneurysmal blood flow from static tissue. The results were analyzed by statistic "t" test. 3D-CEMRA was performed with spoiled gradient-recalled echo and one dose of Gd-DTPA. All data was processed with multi-plannar reformat (MPR) and tomography for the demonstration of aneurysms in detail. All 26 aneurysms were demonstrated successfully by combined application of both cine MRA and 3D-CEMRA. Compared to DSA and conventional 3D-MOTSA, its sensitivity and specificity figures were both 100%. Cine MRA could differentiate the blood flow from the static tissue. The intensity VS time curves of intraaneurysmal blood flow offered fluctuating form and average signal change between systole and diastole period was about 89.8 +/- 37.4; However, under the control group, intraaneurysmal thrombus or cerebral hemorrhage or cavernomas had no significant signal change and the curves offered steady form with the average signal change being about 8.2 +/- 6.3. There was statistically significant difference between the intraaneurysmal blood flow and static tissue (P=0.025, <0.05). 3D-CEMRA was very useful in demonstrating the aneurysmal size, intraaneurysmal thrombus formation, neck and the detailed relationship of the aneurysm to the surrounding structures. It was concluded that the combined application of both cine MRA and 3D-CEMRA might be a valuable clinical tool for the detection of large intracranial aneurysms.

Background and purpose:miR-124 is considered to be a tumor suppressor in multiple tumors, including lung cancer, prostate cancer, bladder cancer, and breast cancer. However, its function is unclear in gastric cancer. This study aimed to explore the expression of miR-124 in human gastric mucosal epithelium cells and different gastric cancer cells, as well as gastric cancer tissues and matched para-cancerous tissues. The correlations of miR-124 expression with gender, age, histological grade, T stage, TNM stage, lymph node metastasis and prognosis of gastric cancer patients were analyzed.Methods:A real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) was employed for detecting the expression of miR-124 in human gastric mucosal epithelium cells and gastric cancer cells. The expression of miR-124 in gastric cancer tissues and matched para-cancerous tissues was detected by in situ hybridization.Results:The RTFQ-PCR results indicated that the expression of miR-124 was down-regulated in MKN-74, MKN-28, MKN-45, MGC-803, SGC-7901 and AGS cells compared to GES-1 cells.In situ hybridization showed that miR-124 was strongly expressed in normal gastric mucosa. However, low expression, focal positive expression or lack of miR-124 expression were observed in gastric cancer tissues. Statistical analysis showed that miR-124 was close-ly correlated to histological stage, TNM stage and node metastasis of gastric cancer patients, but not the age, gender and tumor size. The OS and DFS of the patients with low expression of miR-124 were shorter than that of the patients with high expression of miR-124. Multivariate analysis suggested that miR-124 down-regulation was an independent prog-nostic factor for survival in patients with gastric cancer.Conclusion:miR-124 is down-regulated in gastric cancer cells and tissues. The expression of miR-124 is correlated to histological stage, TNM stage, node metastasis and prognosis.
