Objective To investigate the clinical values of NT-proBNP in left ventricular enlargement(LVE) and left ventricular dysfunction(LVD) of the patients with essential hypertension(EH) to provide a diagnostic basis for their diagnosis .Methods Plas-ma NT-proBNP concentrations in 120 patients with EH and in 29 normal controls were measured ,then the echocardiography exami-nation was performed to determine the left ventricular ejection fraction ( LVEF) ,left ventricular end-diastolic diameter(LVEDD) , left atrium(LA) and left ventricular systolic diameter(LVSDD) .The correlation between plasma NT-proBNP with LVE and LVD was analyzed .The diagnostic accuracy of NT-proBNP was analyzed by using receiver operating characteristic (ROC) curve .Results There were no statistically significant differences in the aspects of age ,sex and serum creatinine between the EH group and con-trol group ,but plasma NT-proBNP level of the former was significantly higher than that of the latter .The NT-proBNP level in the patients with LVE was significantly higher than that in the patients with normal left ventricle (P<0 .05) .The NT-proBNP level in the LVD patients was significantly higher than that in the patients with normal left ventricular function (P<0 .05) .The plasma NT-p roBNP level was positively correlated with LA ,LVEDD and LVSDD(r=0 .518 ,0 .58 ,0 .48 ,P<0 .01) while negatively crrelated with LVEF(r= -0 .61 ,P<0 .01) .The ROC curve showed that when the NT-proBNP was set at 380 pg/mL ,the sensitivity and specificity of NT-proBNP for diagnosing LVE were 80 .6% and 72 .4% ;which for diagnosing LVD were 80 .8% and 77 .4% ,re-spectively .Conclusion NT-proBNP is closely correlated with multiple ultrasonic indicators reflecting the left ventricular function and its level can reliably reflect the left ventricular contraction function ,which can serve as the marker for screening LVE and LVD in the patients with EH .

Objective To observe the effects of rehabilitation intervention on the quality of life (QOL) of patients after coronary artery bypass grafting. Methods Fifty-eight hospital patients in need of coronary artery by-pass grafting (CABG) were randomly assigned to a cardiac rehabilitation group ( rehab ; n = 31 ) or a routine care group (control; n = 27 ). In the rehab group, patients received progressively increasing movement and appropriate psychological intervention. Changes in the medical outcome study short form (SF-36) scores and 6 min walk dis-tances (6MWDs)as well as the length of post-operative stays in hospital were observed in both groups. Results Compared with the control group, patients in the rehab group scored significantly higher on the SF-36. Their physical functioning, general health, vitality, role-emotion and mental health scores improved significantly, their final 6MWDs were longer, and they had significantly shorter average hospital stays after the operation. Conclusions Rehabilita-tion training can improve QOL for patients after coronary artery bypass grafting.

Objective To observe the effects of rehabilitation on the quality of life and capacity of aerobic exercise in patients after coronary artery bypass graft. Methods 58 patients after coronary artery bypass graft were divided into rehabilitation group (n=31) and control group (n=27). Patients in the control group received routine drug treatment out of hospital, while the rehabilitation group was guided regularly for rehabilitation. All patients were surveyed with the MOS item short form health survey (SF-36) and 6 min walking test on the 15th and the 90th day after operation. Results Compared with the control group,the scores of all the items of SF-36 in rehabilitation group improved (P<0.01) except in body pain. The result of 6MWT was also higher in rehabilitation group than in controls(P<0.01). Conclusion Rehabilitation can improve capacity of aerobic exercise and the quality of life of patients after coronary artery bypass grafting.

Objective:To explore the consistency of MRI fast field echo resembling a CT using restricted echo-spacing (FRACTURE) and CT in the evaluation of knee and ankle bone changes.Methods:From November 2020 to November 2021, seventeen patients who underwent CT and MRI FRACTURE examinations of knee joint or ankle joint in the First Affiliated Hospital of Dalian Medical University were retrospectively collected, including 14 patients with knee joint examinations and 3 patients with ankle joint examinations. According to the number of joint components, 80 components were included, including 14 for femur and patella, 17 for tibia and fibula, and 3 for talus, scaphoid, medial cuneiform, medial cuneiform, lateral cuneiform and calcaneus, respectively. The fracture, hyperosteogeny, and bone destruction of the joint bones were evaluated by two observers using CT and FRACTURE images, respectively. Kappa test was used to analyze the consistency of CT and FRACTURE images between observers in the evaluation of joint bone lesions.Results:The Kappa values (95%CI) of the consistency evaluation of fracture, hyperosteogeny, and bone destruction by CT and FRACTURE images were 0.925 (0.823-1.027), 0.905 (0.799-1.011) and 0.895(0.752-1.038) respectively for observer 1, and were 0.963 (0.892-1.034), 0.933 (0.843-1.023) and 0.886 (0.731-1.041) respectively for observer 2. The Kappa values (95%CI) of the consistency evaluation of fracture, hyperosteogeny, and bone destruction by observers 1 and 2 via CT images were 1.000 (1.000-1.000), 0.937(0.851-1.023) and 0.945 (0.839-1.051) respectively, and that by FRACTURE images were 0.962 (0.888-1.036), 0.966 (0.899-1.033) and 0.836 (0.656-1.016) respectively.Conclusion:For the evaluation of fracture, hyperosteogeny, and bone destruction of knee joint and ankle joint, MRI FRACTURE sequence is highly consistent with CT.
