ABSTRACT
Objective@#To investigate the application effect of Power port in contrast-enhanced CT scans.@*Methods@#Totally 220 cancer patients who needed contrast-enhanced CT scans after chemotherapy were selected in Changhai hospital From September 2017 to September 2018, including 110 cases in the observation group and 110 cases in the control group with convenient sampling method.The observation group was injected contrast medium through Power port for CT scans. Contrast medium was injected into the control group by 22G of Peripheral venous access devices (Introcan®). The incidence of contrast medium exosmosis, nursing time and patient satisfaction were compared between the two groups.@*Results@#The incidence of extravasation of contrast medium in the observation group was 0, lower than that in the control group 9.1% (10/110), the difference was significant(χ2=10.476,P=0.015); the nursing time in the observation group was (2.60 ±0.15) minutes per time, which was lower than that in the control group (5.60 ± 5.29) minutes per time), the difference was significant (t=5.934, P=0.000); the patient satisfaction in the observation group was higher than that in the control group, the difference was statistically significant (Z=-12.695, P=0.000).@*Conclusions@#Contrast medium injection through Power port for CT scans can reduce the incidence of contrast medium exosmosis, reduce nursing hours and improve patient satisfaction.

ABSTRACT
Objective To analyze the clinical profiles of lupus mesenteric vasculitis (LMV).Methods Thirty-six SLE patients diagnosed with LMV and 72 SLE patients (1:2) without LMV at West China Hospital between October 2009 and January 2012 were enrolled.The imaging,clinical manifestation,laboratory examinations data were analyzed retrospectively.Quantitative differences were analyzed by the Student's t and Z tests and qualitative data were compared with Chi-square.P value less than 0.05 was considered as statistically significant.Results ① The prevalence of LMV in patients with SLE was 1.2％(36/3 051),while 47％(17/36) as the initial symptom of SLE.Thirty-six LMV patients were all female.The prevalence of abdominal pain was 78％(28/36),nausea or vomitting was 58％(21/36),abdominal distension was 50％(18/36),diarrhea was 47.2％ (17/36),intestinal perforation was 3％ (1/36) and incomplete obstruction was 8％ (3/36).Enhanced CT scan showed 81％(25/31) patients suffered from intestinal dilation and (or) mesenteric edema;SLEDAI (17±5),C3 (0.44±0.25) g/L,C4 (0.10±0.09) g/L,Z value on above items were 4.30,-3.85 and-2.94 respectively compared to SLE patients without LMV,and all P＜0.05,the differemces were significant.In addition,Also,the proportion of ANA and anti-ENA antibody showed no significant difference.68.6％(13/36) patients were also diagnosed with lupus nephritis;61％(22/36) patients were treated with methylprednisolone more than 200 mg/d resulting in relief of symptom.Conclusion Female patients with SLE may be more likely to suffer from LMV;Enhanced abdominal CT scan is still essential to the diagnosis of LMV.LMV is correlated with urinary system malfunction.LMV always occurs in active lupus with low C3 and C4 level.More than half patients should be treated with corticosteroid and cyclophosphamide pulse therapy.
ABSTRACT
Objective:To compare the results of dual-phase enhanced CT scan and pathological diagnosis of ovarian corpus luteum cyst rupture.Methods: Thirty four cases of ovarian corpus luteum cyst rupture were treated in our hospital from April 2012 to April 2015 were retrospectively analyzed.Results: Among the 34 cases of patients, 28 cases before surgery CT accurate diagnosis of ovarian corpus luteum cyst, 6 cases before surgery CT did not accurately diagnose ectopic pregnancy bleeding was first diagnosed. In terms of the lesion, 22 cases of the right ovary and 12 cases were left ovary. Ruptured corpus luteum cyst diameter in 4.3-7.3cm, averaging (5.1±1.4)cm, the lack of complete cyst wall, visible break, there exists in the blood clot and the surrounding cyst; 20 cases with contrast extravasation, sheet or strip was present in high density around the cyst was the main clinical manifestations; a lot of low density liquid accumulated in the abdominal cavity; 28 cases with cystic density increased, the presence of a blood clot within the cyst was the main clinical manifestations. Surgical results were consistent with observed preoperative CT diagnosis. All patients were pathologically confirmed corpus luteum cyst rupture.Conclusion: Dual-phase enhanced CT scann has higher value in the diagnosis of ovarian corpus luteum cyst rupture bleeding, so is worthy of promotion.
