基于Andersen行为模型的消化道肿瘤患者支持性照顾需求现状及影响因素分析

目的调查消化道肿瘤患者的支持性照顾需求现状并分析其影响因素。方法于2019年1—10月间,采用便利抽样的方法,抽取重庆市三峡中心医院内消化道肿瘤患者共370例,采用一般资料调查表、癌症病人支持性照顾需求简明问卷(SCNS-SF34)、医院焦虑和抑郁量表(HADS)、社会网络支持量表(LSNS)进行问卷调查。以Andersen行为模型为基础,将调查内容中关于消化道肿瘤患者支持性照顾需求的影响因素分别纳入倾向性因素、使能因素和需求性因素中,构建4个线性回归模型进行分析,并检验各模型的拟合优度,采用多元线性回归分析消化道肿瘤患者支持性照顾需求的影响因素。结果共发放问卷370份,回收有效问卷365份,有效回收率为98.6%。365例消化道肿瘤患者支持性照顾需求总均分为(3.42±0.54)分,其中生理与日常生活需求>健康信息需求>照顾与支持需求>心理需求>性需求。多元线性回归分析结果显示:倾向性因素中年龄、婚姻状况,使能因素中的家庭平均月收入、疾病负担能力、社会网络支持,需求性因素中的病程、疾病分期、疼痛情况、焦虑程度、抑郁程度是消化道肿瘤患者支持性照顾需求的主要影响因素(P<0.05)。结论消化道肿瘤患者有较高的支持性照顾需求,其需求受多种因素的影响,建议临床医护人员针对不同需求患者进行针对性满足,并对不同影响因素进行综合考量并加以分类分析。     

Bronchogenic cyst of the stomach:A case report

BACKGROUND Gastric bronchogenic cysts(BCs)are extremely rare cystic masses caused by abnormal development of the respiratory system during the embryonic period.Gastric bronchial cysts are rare lesions first reported in 1956;as of 2019,only 37 cases are available in the MEDLINE/PubMed online databases.BCs usually have no clinical symptoms in the early stage,and their imaging findings also lack specificity.Therefore,they are difficult to diagnose before histopathological examination.CASE SUMMARY A 55-year-old woman presented at our hospital with intermittent epigastric pain.She had a slightly high level of serum carbohydrate antigen 72-4(CA 72-4).Endoscopic ultrasound found that a cystic mass originated from the submucosa of the posterior gastric wall near the cardia,indicating a diagnosis of cystic hygroma of the stomach.Furthermore,a computed tomography scan demonstrated a quasi-circular cystic mass closely related to the lesser curvature of the gastric fundus with a low density.Because the imaging examinations did not suggest a malignancy and the patient required complete resection,she underwent laparoscopic surgery.As an intraoperative finding,this cystic lesion was located in the posterior wall of the fundus and contained some yellow viscous liquid.Finally,the pathologists verified that the cyst in the fundus was a gastric BC.The patient recovered well with normal CA 72-4 levels,and her course was uneventful at 10 mo.CONCLUSION This is a valuable report as it describes an extremely rare case of gastric BC.Moreover,this is the first case of BC to present with elevated CA 72-4 levels.     

Eulerian Algorithms for Computing the Forward Finite Time Lyapunov Exponent Without Finite Difference upon the Flow Map

In this paper, effective Eulerian algorithms are introduced for the computation of the forward finite time Lyapunov exponent (FTLE) of smooth flow fields. The advantages of the proposed algorithms mainly manifest in two aspects. First, previous Eulerian approaches for computing the FTLE field are improved so that the Jacobian of the flow map can be obtained by directly solving a corresponding system of partial differential equations, rather than by implementing certain finite difference upon the flow map, which can significantly improve the accuracy of the numerical solution especially near the FTLE ridges. Second, in the proposed algorithms, all computations are done on the fly, that is, all required partial differential equations are solved forward in time, which is practically more natural. The new algorithms still maintain the optimal computational complexity as well as the second order accuracy. Numerical examples demonstrate the effectiveness of the proposed algorithms.
