Objective To explore the MSCT characteristics of gastric schwannoma (GS).Methods 1 6 patients with pathologically verified GS were included in our study.The MSCT images were analysed retrospectively.Results 1 6 participants were determined with solitary nodule,which located in gastric antrum,body and fundus,respectively with 5 cases,10 cases and 1 case.13 of them showed morphologically as round or ovoid shape,while 3 of them grew irregularly lobulated lesion.For their growth pattern,1 3 tumors presented as bilateral growth,1 lesion appeared intra-cavitary growth,1 grew outside the cavity fields.However,1 case was hard to confirm the growth pattern due to the gastroduodenal intussusception.14 tumors appeared uniform density,1 showed a little necrosis and 1 had dotted calcification,all the lesions were emerged as progressive enhancement with inhomogeneous feature.Conclusion GS mostly located in gastric body or antrum,with round or ovoid appearence,well-defined border,and bilateral growth pattern,necro-sis and calcification are rare,enhanced progressively with homogeneous feature,with no surrounding invasion and metastasis.

OBJECTIVE To discuss the clinical utility of the self-made curved laryngoscope.METHODS Clinical data of 198 patients with vocal cord polyps from September 2012 to October 2014 was analyzed retrospectively in which 99 cases were treated under the self-made curved larngoscopic surgeries (curved laryngoscope group) and 99 cases were treated by microlaryngoscopic surgeries (microlaryngoscope group).The duration of follow-up was 3 months in all patients.The clinical efficacy, times of inserting laryngoscope, glottic exposure and operation complications of two kinds of operations were observed and compared.RESULTS The total clinical efficacy in curved laryngoscope group showed no significant difference as compared with that in microlaryngoscope group. But for patients with difficult laryngeal exposure,the efficacy of curved laryngoscopic surgery was significantly better compared with that in the microlaryngoscopic surgery group. The results of times of inserting laryngoscope, glottic exposure and operation complications in the self-made curved larngoscope group were all better than those in microlaryngoscope group (P <0.05). CONCLUSION The operation under the self-made curved laryngoscope is a minimal invasive procedure to the laryngeal mucosa, with such more advantages like clear view of operation field and accurate management to the lesion tissue.Furthermore, the self-made curved laryngoscopic surgery is the first choice for the treatment of patients with difficult laryngeal exposure.

Objective To investigate the optimum threshold value of tracking and triggering technique (surestart) in imaging of coronary artery by 16-slice row CT. Methods 60 patients enrolled in the enhanced scan of coronary artery imaging were divided into 2 groups (group a : heart rate 70 beats/per minute ). The quality of images collected under different threshold value and heart rate was compared. The image quality of coronary artery was ranked by 3 levels, namely, level A, B and C. The data were statistically analyzed. Results The image quality triggered by 160 HU of group b was level A. The image quality triggered by 180 HU of group a was level A. Conclusion The optimum surestart is 180 HU when the heart rate 70 beats/per minute.

Objective To investigate the risk factors and prognosis of no-reflow phenomenon in patients after percutaneous coronary intervention(PCI).Methods Retrospectively analyzed 524 patients with acute coronary syndrome after PCI of which 427 patients had detailed record.Angiographic no-reflow phenomenon was designated as TIMI≤2 flow without mechanical obstruction of embolism,thrombus,dissection and spasm.Normal flow designated as TIMI 3 flow.Using random count table of Excel,70 patients were randomized from 393 patients with coronary flow TIMI 3 after PCI as the control normal flow group.Results The no reflow group enrolled 34 patients.Compared with the normal flow group,their incidence of AMI and diabetes,the blood insulin level and mean leukocyte count were significantly higher.The incidence of MACE in and out of hospital was higher in the no reflow group than the normal flow group.Within the no reflow group,the EF decreased while the LVEDD increased significantly PCI.Conclusion History of diabetes,blood insulin level and leukocyte count may be the risk factors of no-reflow.On the other hand,the no reflow phenomenon maybe a prognostic factor of MACE,ventricular remodeling and heart function for patients after PCI.

BACKGROUND:Thoracolumbar fracture often accompanies with the injury of adjacent intervertebral disc. Traditional posterior short-segment fixation does not deal with the injured intervertebral disc, which may be the main reason for kyphosis in patients after surgery.
OBJECTIVE:To investigate the effect of injured intervertebral disc on kyphosis angle in patients with single vertebral thoracolumbar fracture after treated with posterior short-segment fixation alone.
METHODS:From January 2009 to June 2014, 40 cases of thoracolumbar fractures were treated in Jinan Central Hospital. They were folowed-up at preoperation, 2 and 12 months after operation and 6 months after internal fixation removal. Data were obtained from X-ray and MRI scanning. According to the preoperative MRI images, cases were assigned to observation group (17 cases) and control group (23 cases) according to injury and non-injury intervertebral disc. Data of vertebral wedge angle, sagittal plane kyphosis, proximal intervertebral disc angle, sagittal index and degeneration classification of proximal intervertebral disc angle from two different groups were analyzed at each folow-up time point (18-30 months, averagely 23.6 months).
RESULTS AND CONCLUSION:(1) Imaging parameters: sagittal plane kyphosis was significantly severer at 6 months than that at 2 months in both groups (P < 0.05). Sagittal plane kyphosis, proximal intervertebral disc angle and sagittal index were greater in the observation group than in the control group at 12 months after surgery and 6 months after fixator removal (P < 0.05). (2) Degeneration classification of proximal intervertebral disc angle: Pearce degeneration grade of proximal intervertebral disc was significantly higher in the observation group than in the control group at 2 months after surgery and 6 months after internal fixation removal (P < 0.05). (3) Results suggested that kyphosis may appear in the patients with thoracolumbar fracture after a posterior short-segment fixation alone, and the injured disc may lead to more severe kyphosis.
