Objective:To explore the effects of closed reduction elastic intramedullary nail fixation (CR-ESIN) on the rehabilitation process and joint function of children with femoral fractures.Methods:A retrospective study was conducted on 102 children with femoral fractures who underwent internal fixation surgery in our hospital from April 2024 to June 2025. Based on different surgical plans, 51 children who underwent CR-ESIN treatment were included in the CR-ESIN group, and the remaining 51 children who underwent traditional open reduction plate internal fixation (ORIF) treatment were included in the ORIF group. The treatment status, rehabilitation process, incidence of surgical complications, joint function recovery, and burden during the removal of internal fixation materials were compared between the two groups of children.Results:Under different surgical plans, the surgical time, intraoperative blood loss, postoperative hospitalization time, brace use time, and complete weight-bearing time of the CR-ESIN group were (60.29 ± 5.44) min, (50.52 ± 5.49) mL, (6.22 ± 1.34) d, (4.15 ± 1.33) weeks, and (6.81 ± 1.34) weeks, lower than the ORIF group [(76.33 ± 8.29) min, (190.48 ± 20.51) mL, (8.17 ± 1.65) d, (6.32 ± 1.48) weeks, and (7.82 ± 2.17) weeks] (t=11.552，47.076，6.552，8.322，2.828; P<0.05). The incidence of surgical complications in the CR-ESIN group was 5.88% (3/51) lower than the ORIF group 19.61% (10/51) (x2=4.320; P<0.05). The hip flexion range of motion, extension range of motion, and PODCI scores of the CR-ESIN group were (132.44 ± 22.52) °, (20.39 ± 4.47) °, and (75.14 ± 6.29) points, higher than the ORIF group [(120.28 ± 20.37) °, (17.55 ± 3.12) °, and (70.31 ± 5.36) points]. The length difference between the bilateral femurs was (1.52 ± 0.39) cm, which was lower than the ORIF group (3.08 ± 0.44) cm (t=2.860，3.721，4.174，18.948; P<0.05). The length of the surgical incision, the duration of the extraction surgery, the amount of bleeding during the extraction surgery, and the rate of re fracture in the CR-ESIN group were all lower than the ORIF group (t/x2=31.706，8.298，38.448，4.883; P<0.05).Conclusion:CR-ESIN can improve the surgical efficiency and reduce the risk of bleeding in children with femoral fractures. Compared with traditional ORIF, this procedure is beneficial for accelerating the recovery process of children, reducing the incidence of postoperative complications, promoting joint function recovery, and reducing the burden of internal fixation removal stage.

Objective:To analysis of the association between blood-brain barrier markers Occludin (OCLN), Claudin-5 (CLDN5) and the degree of neurological damage and poor prognosis in PD patients.Methods:The research subjects selected 180 PD patients who visited our hospital from June 2024 to June 2025, as well as 180 healthy volunteers who underwent examinations during the same period. They were divided into a case group and a control group, and the differences between the two groups in terms of OPLN and CLDN5 were compared. According to the severity of the disease, PD patients were divided into early group (50 cases), middle group (65 cases), and late group (65 cases). The differences in OCLN, CLDN5, and nerve injury markers among the three groups of patients were compared, and the correlation between OCLN, CLDN5, and nerve injury markers in the late group of patients was analyzed. Statistically analyze the occurrence of poor prognosis in enrolled patients, compare the differences in OCLN, CLDN5, and nerve injury markers among patients with different prognoses, analyze the factors affecting the prognosis of PD patients, and verify the predictive power of OCLN and CLDN5 for poor prognosis in PD patients.Results:The peripheral blood levels of OCLN and CLDN5 in the case group were higher than the control group (t=50.450，51.670; P<0.05). The levels of OCLN, CLDN5 NSE,UCH-L1,NfL, and GFAP in peripheral blood of the late stage group were higher than those of the mid stage and early stage groups (F=280.611，378.453，82.254，122.413，185.272，257.733; P<0.05). The OCLN and CLDN5 in the late stage group were positively correlated with NSE, UCH-L1, NfL, and GFAP (r=0.411，0.457，0.505，0.494，0.465，0.425，0.491，0.503; P<0.05). The incidence of poor prognosis in 180 PD patients was 28.89% (52/180). The peripheral blood levels of OCLN, CLDN5, NSE, UCH-L1, NfL, and GFAP in the poor prognosis group were higher than those in the good prognosis group (t=17.096，14.405，7.632，6.903，11.695，10.702; P<0.05). The results of logistic multiple regression analysis showed that high expression of peripheral blood OCLN, CLDN5, NfL, and GFAP were risk factors for poor prognosis in PD patients. According to ROC test, the combined detection of peripheral blood OCLN and CLDN5 has a higher AUC for predicting poor prognosis of PD than the detection of peripheral blood OCLN and CLDN5 alone (DeLong test, P<0.05).Conclusion:Peripheral blood OCLN and CLDN5 can exacerbate and continuously increase the degree of nerve damage in PD patients. Combined detection of peripheral blood OCLN and CLDN5 may serve as an important auxiliary tool for predicting poor prognosis in patients.

Objective:To explore the application value of dapagliflozin and its short-term cardiac function improvement effect in patients with type 2 diabetes mellitus (T2DM) combined with unstable angina (UA) after percutaneous coronary intervention (PCI). Methods: This was a single-center, randomized controlled trial. A total of 90 patients with type 2 diabetes mellitus (T2DM) complicated with unstable angina (UA) after percutaneous coronary intervention (PCI) were enrolled and randomly assigned to a dapagliflozin group (n=43) and a metformin group (n=47). Hypoglycemic agents were adjusted routinely to ensure consistent glycemic control intensity between the two groups. During treatment and at 6–12 months after treatment, left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD) were measured by echocardiography, and venous blood samples were collected to determine the level of N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) for the evaluation of cardiac function changes. Results: During the 6-month follow-up after PCI treatment, the N-terminal pro-brain natriuretic peptide (NT-proBNP) level in the observation group decreased significantly (P<0.01), and the left ventricular ejection fraction (LVEF) increased significantly (P<0.01).Compared with the control group, the NT-proBNP level in the observation group was notably lower (P<0.01) and also remained below that of the control group. Conclusion: For type 2 diabetes mellitus (T2DM) patients complicated with unstable angina pectoris after PCI, adjuvant treatment with dapagliflozin for 6 months can significantly improve cardiac function surrogate markers such as NT-proBNP and LVEF, with favorable safety profile.
