Objective To observe the value of contrast-enhanced ultrasound(CEUS)for evaluating DeBakey Ⅰ aortic dissection involved renal artery.Methods Totally 137 patients with DeBakey Ⅰ aortic dissection involved renal artery were retrospectively enrolled,including 132 cases involved unilateral and 5 cases involved bilateral renal arteries.The opening of totally 274 renal arteries in bilateral kidneys were observed.Taken CT angiography(CTA)as reference standard,the renal artery opened in true lumen was considered as unaffected,while opened in false lumen or true-false lumen were both considered as affected.Relative CEUS manifestations were observed,and their value for evaluating involved renal artery or not were analyzed.Results CTA showed that 132 renal arteries opened in true lumens,90 opened in false lumens and 52 opened in true-false lumens.CEUS diagnosed 131 renal arteries opened in true lumens,111 opened in false lumens and 32 opened in true-false lumens,and the sensitivity for diagnosing DeBakey Ⅰ aortic dissection involved renal artery was 90.84％,81.08％and 90.63％,respectively.The consistency between CEUS and CTA for evaluating renal artery opened in true lumen or false lumen was good(Kappa=0.786).Logistic regression analysis showed that the time to peak(TTP)and peak intensity(PI)of time intensity curve(TIC)were both impact factors for differentiating renal artery opened in true lumen or false lumen,as well as true lumen or true-false lumen(both P＜0.05),while the area under the curve(AUC)of TIC was impact factor for differentiating renal artery opened in true lumen or false lumen(P＜0.05).The AUC of receiver operating characteristic curve of the combination of TTP,PI and AUC of TIC for differentiating renal artery opened in true lumen or false lumen,true lumen or true-false lumen and false lumen or true-false lumen was 0.703,0.686 and 0.493,respectively.Conclusion CEUS was helpful for evaluating DeBakey Ⅰ aortic dissection involved renal artery.

Objective:The expression of serum free light chain(FLC)is abnormal in various diseases,but its role in lung cancer remains unclear.This study aims to investigate the expression and diagnostic value of serum FLC in lung cancer. Methods:A total of 80 lung cancer patients treated at Xiangdong Hospital,Hunan Normal University from January to December 2021 were selected as the lung cancer group.Another 80 healthy individuals undergoing routine physical examinations during the same period were chosen as the control group.General information and serum κFLC and λFLC levels were collected for all subjects.Clinical indicators such as serum carcinoembryonic antigen(CEA),cytokeratin fragment antigen 21-1(CYFRA21-1)levels,tumor diameter,histological type,TNM stage,and lymph node metastasis status were recorded for lung cancer patients.The expression levels of serum FLC[κFLC,λFLC,and FLC(κ+λ)]were compared between the lung cancer group and the control group.Lung cancer patients were grouped based on gender,age,smoking history,tumor diameter,TNM stage,histological type,and lymph node metastasis to compare differences in serum κFLC and λFLC levels.Receiver operating characteristic(ROC)curves were used to evaluate the diagnostic value of serum FLC alone and in combination with other indicators in lung cancer. Results:The expression levels of serum FLC(κ+λ)and κFLC were significantly higher in the lung cancer group than those in the control group(both P＜0.001),while there was no significant difference in serum λFLC levels between the 2 groups(P＞0.05).There were no significant differences in serum κFLC levels among lung cancer patients with different tumor diameters,histological types,or TNM stages(all P＞0.05);however,serum κFLC levels were higher in lung cancer patients with lymph node metastasis than in those without,with statistical significance(P=0.033).There were no significant differences in serum λFLC levels based on tumor diameter or histological type(both P＞0.05),but serumλFLC levels were higher in stage Ⅲ+Ⅳ and lymph node metastatic lung cancer patients compared to stage Ⅰ+Ⅱ and non-metastatic patients,with statistical significance(P=0.033 and P=0.019,respectively).The area under the curve(AUC)for κFLC and CEA in diagnosing lung cancer showed no significant difference(P=0.333).The combination ofκFLC+CYFRA21-1 had the highest diagnostic efficacy(AUC=0.875)and sensitivity(71.3％).The AUC for the combined diagnosis of κFLC+λFLC+CEA+CYFRA21-1 was 0.915(95％CI 0.860 to 0.953,P＜0.001). Conclusion:Serum FLC is highly expressed in lung cancer and is associated with its invasion and metastasis.Serum FLC,particularly κFLC,has diagnostic value for lung cancer,and the combined detection of FLC,CEA,and CYFRA21-1 offers the best diagnostic efficacy.

The geometric bone model of patients is an important basis for individualized biomechanical modeling and analysis, formulation of surgical planning, design of surgical guide plate, and customization of artificial joint. In this study, a rapid three-dimensional (3D) reconstruction method based on statistical shape model was proposed for femur. Combined with the patient plain X-ray film data, rapid 3D modeling of individualized patient femur geometry was realized. The average error of 3D reconstruction was 1.597-1.842 mm, and the root mean square error was 1.453-2.341 mm. The average errors of femoral head diameter, cervical shaft angle, offset distance and anteversion angle of the reconstructed model were 0.597 mm, 1.163°, 1.389 mm and 1.354°, respectively. Compared with traditional modeling methods, the new method could achieve rapid 3D reconstruction of femur more accurately in a shorter time. This paper provides a new technology for rapid 3D modeling of bone geometry, which is helpful to promote rapid biomechanical analysis for patients, and provides a new idea for the selection of orthopedic implants and the rapid research and development of customized implants.

Objective:To investigate the status of anticipatory grief among the main caregivers of maintenance hemodialysis patients, and to analyze its influencing factors.Methods:From April 2021 to July 2021, the main caregivers of 180 patients undergoing maintenance hemodialysis in Xiangdong Hospital Affiliated to Hunan Normal University and Liling Traditional Chinese Medicine Hospital in Hunan Province, were selected by convenience sampling method for the research object. The survey was carried out using the General Information Questionnaire, the Anticipatory Grief Scale and the Zarit Caregiver Burden Interview, multiple linear regression was used to analyze the influencing factors of anticipatory grief in the main caregivers of maintenance hemodialysis patients.Results:The total score of Anticipatory Grief Scale in the main caregivers of maintenance hemodialysis patients was 84.43±12.02, and the total score of Zarit Caregiver Burden Interview was 24.92 ± 7.98, which were positively correlated ( r = 0.557, P<0.01).In the multiple linear regression analysis, the caregiver ′s education level, age, gender, care burden and per capita monthly income and the patient ′s age were the influencing factors of anticipatory grief for the main caregivers of maintenance hemodialysis patients ( t values were -5.54-8.75, all P<0.05), which could explain 54.1% of the total variance. Conclusions:The anticipatory grief of the main caregivers of maintenance hemodialysis patients is at a relatively serious level. Medical care should pay more attention to the caregivers and their sadness in their communication, so as to detect problems in time, so as to take targeted measures to the current situation, which is effective to improve their level of grief and improve the quality of care.

Objective To investigate the value of urine liver?type fatty acid?binding proteins(L?FABP) for early diagnosis and progress predicting of acute kidney injury(AKI)after lung transplantation. Methods Urine L?FABP and Scr blood samples in perioperative periods of 119 lung transplant recipients (hospitalized between 2013?2014)were involved in the research. Patients were divided into AKI group and non?AKI group according to KDIGO. Changes in urine L?FABP and Scr of two groups at various time points were recorded. Results Of 119 patients,57 developed AKI after surgery. Urine L?FABP from 0 h to 48 h in the two groups increased significantly, and the difference at 6 h to 48 h between the two groups is significant. In terms of diagnostic value,ROC area of urine L?FABP at 6h is 0.818. When 2254.52 ng/mg Cr was taken as diagnostic dividing line ,sensitivity and specificity was 0.782 and 0.814. In predicting AKI progression ,AUC below AUC of urine L?FABP 0.852. When 4313.17 ng/mgCr was taken as diagnostic dividing line ,sensitivity and specificity was 0.867 and 0.700. Conclusion Urinary L?FABP appears to be a sensitive and specific marker of AKI in lung transplant recipients ,could be a biological marker in the early diagnosis and progression tendency of AKI.
