Objective To analyze the diagnostic value and misdiagnosis reasons of MRI in benign and malignant prostatic transitional zone lesions.Methods A total of 147 patients with prostatic transitional zone lesions were selected.The diagnostic value and misdiagnosis reasons of MRI in benign and malignant prostatic transitional zone lesions were analyzed.Results The accuracy rate of MRI diagnosis was 78.23％,and the misdiagnosis rate was 21.77％.MRI had high consistency with the pathological diagnosis results(Kappa=0.816,P＜0.001).MRI had high diagnostic value in benign and malignant prostatic transitional zone lesions,and the area under the curve(AUC)was 0.767.The shape,signal uniformity,boundary condition,capsule condition,diffusion weighted imaging(DWI)signal intensity,apparent diffusion coefficient(ADC)value,and time-signal intensity curve type of the lesion were all independent risk factors for misdiagnosis of benign and malignant prostatic transitional zone lesions using MRI(P＜0.05).Conclusion MRI has high diagnostic value in benign and malignant prostatic transitional zone lesions.The causes of misdiagnosis are lesion shape,signal uniformity,boundary condition,capsule condition,DWI signal intensity,ADC value,and time-signal intensity curve type.

Objective:To investigate the effect of blood flow restriction training (BFRT) on the rehabilitation of lower limb joint function in persons with rheumatoid arthritis (RA).Methods:Sixty RA patients were randomly divided into an observation group and a control group, each of 30. Both groups were given conventional slow-acting anti-rheumatic medication with low-dose glucocorticoids. Everyone received basic exercise training including joint training and plyometric training, but the observation group additionally received BFRT training during which constant pressure in an inguinal cuff restricted blood flow to the lower limbs. The observation group′s training program also included double leg push-ups and double knee extensions. Before, and 12 weeks after the intervention, the joint symptoms were assessed using swollen joint counts out of 28 joints (SJC28), tender joint counts out of 28 joints (TJC28) and pain reported using a visual analogue scale (VAS). Lower limb motor functioning was assessed using a timed-stands test (TST) and the timed-up-and-go (TUG) test. Life quality was evaluated using a health assessment questionnaire (HAQ) and arthritis self-efficacy scale-8 (ASES-8). Disease activity was quantified using a clinical disease activity index (CDAI), a simplified disease activity index (SDAI) and disease activity scoring with a 28-joint count (DAS28).Results:There were no significant differences between the two groups before the intervention. After the intervention all of the indicators except the DAS28 had improved significantly in the observation group. At that point they were also all better than the control group′s averages, where no significant improvement was observed. No serious adverse events occurred in either group during the experiment.Conclusions:BFRT can safely relieve joint symptoms and improve the lower limb motor functioning and life quality of RA sufferers. It is worthy of further clinical research and promotion.

【Objective:】 To understand the current situation of nurses’ professional quality of life in China and its correlation with benefit findings, so as to provide reference for formulating targeted measures to improve nurses’ professional quality of life in China. 【Methods:】 Questionnaire star was used to conduct a cross-sectional survey of 11 924 registered nurses in China from January 2022 to April 2022 using the General Information Questionnaire, the Professional Quality of Life Scale (ProQOL) and the General Benefit Discovery Scale (GBFS). SPSS 22.0 software was used for data analysis. 【Results:】 The scores of various dimensions of nurses’ ProQOL scale were: compassion satisfaction was (32.71±6.81) points, burnout was (27.38±5.20) points, secondary traumatic stress was (28.44±6.67) points, and the total score of GBFS was (100.90±18.04) points. The results of multiple linear stepwise regression showed that the main influencing factors of compassion satisfaction were marital status, position, work unit level and educational background (P<0.05). The main influencing factors of burnout were position, professional title, work unit level and whether there were children to be taken care of at home (P<0.05). The main influencing factors of secondary traumatic stress were education background, marital status, professional title, whether there was an old person to be taken care of at home, whether to take care of COVID-19 patients, whether to be an epidemic support staff and position (P<0.05). Benefit finding independently predicted the three dimensions of nurses’ professional quality of life (P<0.001). 【Conclusions:】 Chinese nurses’ professional quality of life was at a moderate level and it was significantly affected by benefit finding. Attention should be paid to factors such as marital status, work unit level, position, professional title, education background, whether there was an old person to be taken care of at home, whether to take care of COVID-19 patients, so as to improve the level of nurses’ benefit finding, promote their personal growth, provide good job guarantee, and improve Chinese nurses’ professional quality of life.
