Objective To analyze the crucial factors which affect the hospitalization expenses of patients with uterine adenomyosis, in order to take corresponding measures. Methods A total of 583 patients diagnosed with uterine fibroids reported by hospitals in urban areas of Suining city through hospital quality monitoring system between December 2013 and December 2015 were included in this study. The main reasons for the expense structure was described by Pareto’s law. The importance of hospitalization expense influencing factors was analyzed by neural network model, and single factor analysis was used to analyze important influencing factors of hospitalization expenses. Results The main factors influencing hospitalization expenses included length of stay in hospital, operation techniques and illness conditions, and their importance value was respectively 0.581, 0.175 and 0.088. Conclusion Based on hospitalization expenses, length of stay in hospital and expense structure, high intensity focused ultrasound therapy is more reasonable in the treatment of uterine adenomyosis.
目的 总结束胸后16排螺旋CT扫描在诊断危重小儿气管及支气管异物中的作用。 方法 对2011年9月－2012年2月4例气管支气管异物危重患儿用自制束缚带束胸后行CT扫描，扫描后所得图像与2009年5月－2011年8月8例既往工作中未行束胸CT扫描危重患儿气管支气管异物图像进行比较（其中1例为同一患儿行常规及束胸后CT检查），并进行图像后处理，包括多平面重建、气管支气管树重建、CT仿真内窥镜；并观察束胸检查前后患儿血氧饱和度（SpO2）变化情况；其中1例进行束胸前后胸廓最大径线比较。 结果 束胸后CT扫描能明显降低呼吸运动伪影，对气管支气管异物的发现率有明显提高；检查前后患儿SpO2未见明显变化；1例束胸后胸廓最大径线缩小0.8 cm。 结论 束胸后16层螺旋CT扫描能最大限度的避免呼吸运动伪影，使得气管支气管异物能够快速准确诊断，为后期实施适时治疗提供有效影像资料，进而降低该病的并发症及病死率，并且在束胸检查前后患儿SpO2无明显变化。
Objective To discuss the clinical application value of CT angiography (CTA) in traumatic pelvic artery pseudoaneurysm and dissecting aneurysm. Methods A total of 8 patients including 7 with traumatic pelvic artery pseudoaneurysm and 1 with dissecting aneurysm diagnosed by CTA in Suining Central Hospital from August 2012 to January 2016 were enrolled in this study, in whom 6 patients with traumatic pseudoaneurysm treated with embolotherapy were confirmed by digital subtraction angiography. Image post-processing techniques of CTA including curve planar reformation, multiplanar reconstruction and volume rendering were used. Results In the seven patients diagnosed as solitary traumatic pelvic artery pseudoaneurysm by CTA, 3 had superior gluteal artery pseudoaneurysm, 2 had inferior gluteal artery pseudoaneurysm, and 2 had external iliac artery pseudoaneurysm. The 7 pseudoaneurysms were pouch-shaped with the short diameters ranged from 9 to 64 mm and the long diameters ranged from 11 to 78 mm. Six locations of artery laceration were displayed clearly, thereinto 1 case was combined with arteriovenous fistula. In addition, a vessel occlusion caused by the limitation of right external iliac artery dissecting aneurysm and the thrombosis in left side of the external iliac artery was found in 1 case. Conclusions As a non-invasive diagnostic technique, CTA can accurately diagnose traumatic pelvic artery pseudoaneurysm and dissecting aneurysm, clearly display the location relationship of pseudoaneurysm and its parent artery, and find whether arteriovenous fistula exists. Beyond that, the true and false lumen of dissecting aneurysm can be precisely identified by this technique. CTA can provide important image information for formulating individual treatment plan.
ObjectiveTo explore the effectiveness of proximal femoral nail antirotation (PFNA) assisted by mesh locator in treatment of intertrochanteric fracture in the elderly.MethodsNinety-four elderly patients with intertrochanteric fractures admitted between August 2014 and July 2017 were selected as the study subjects. They were randomly divided into trial group (48 cases) and control group (46 cases). In trial group, PFNA was implanted assisted by mesh locator after closed reduction; while in control group, PFNA was implanted by conventional method. There was no significant difference between the two groups in terms of gender, age, cause of injury, time from injury to admission, fracture side and classification, and medical complications (P>0.05). The operation time, intraoperative blood loss, fluoroscopy times, hospital stay, incision length, and complications were recorded. Visual analogue scale (VAS) was used to evaluate the degree of pain at 3 days after operation, and Harris score was used to evaluate hip function before operation and at 3, 6, and 9 months after operation.ResultsCompared with control group, the operation time and incision length of trial group shortened, the blood loss and fluoroscopy times reduced, the pain after operation alleviated obviously; the differences between the two groups were significant (P<0.05). There was no significant difference in hospital stay between the two groups (P>0.05). The patients in both groups were followed up 9-12 months, with an average of 10.6 months. X-ray films showed that the fractures healed in both groups, and the healing time in control group was (11.2±3.2) weeks, while that in trial group was (11.6±2.9) weeks, showing no significant difference between the two groups (t=1.262, P=0.120). There was no significant difference in Harris score between the two groups before operation and at 3, 6, and 9 months after operation (P>0.05). There was 1 case of incision infection, 2 cases of coxa vara, and 1 case of pressure ulcer in trial group, and the incidence of complications was 8.3%. There was 1 case of coxa vara, 2 cases of pressure ulcer, and 1 case of internal fixation loss in control group, and the incidence of complications was 8.7%. There was no significant difference in the incidence of complications between the two groups (χ2=0.783, P=0.112).ConclusionIt is feasible to implant PFNA assisted by mesh locator in treatment of intertrochanteric fracture in the elderly. Compared with the traditional operation, it can shorten the operation time, shorten the incision, and relieve the pain after operation.
