Objective To explore the effect of indobufen combined with intelligent resistance training on platelet function and cardiac function in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). Methods A total of 60 ACS patients who underwent PCI stent implantation in our hospital from January 2024 to December 2025 were selected and randomly divided into an observation group and a control group, with 30 patients in each group. The control group was given conventional treatment combined with clopidogrel 75 mg/d, while the observation group was given conventional treatment combined with indobufen (100 mg/time, twice a day) + intelligent resistance training intervention. Both groups received continuous intervention for 3 months. The arachidonic acid (AA)-induced and adenosine diphosphate (ADP)-induced platelet aggregation rates were compared between the two groups before intervention, 1 month and 3 months after intervention. The incidence of major adverse cardiovascular events (MACE) was followed up for 3 months, and the cardiac function indexes [left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD)] were compared before and after intervention. Results Before intervention, there were no significant differences in platelet aggregation rates, LVEF and LVEDD between the two groups (P > 0.05); at 1 month and 3 months after intervention, the reduction amplitudes of AA-induced and ADP-induced platelet aggregation rates in the observation group were significantly greater than those in the control group (P < 0.05); after 3 months of intervention, LVEF in the observation group was significantly higher than that in the control group, and LVEDD was significantly lower than that in the control group (P < 0.05); after 3 months of follow-up, there was no significant difference in the incidence of MACE between the two groups (P > 0.05). Conclusion Indobufen combined with intelligent resistance training can more significantly inhibit platelet aggregation, more effectively improve cardiac function indexes in ACS patients after PCI, and has good safety.

Objective To investigate the clinical effect of platelet-rich plasma(PRP) combined with core decompression in the treatment of early spontaneous osteonecrosis of the knee(SONK). Methods A retrospective analysis of SONK patients with Koshino stage I and Ⅱ admitted to our hospital from June 2015 to June 2020 was carried out. According to the different treatment methods, patients were divided into core decompression group (control group, 21 patients), and knee joint cavity PRP injection combined with core decompression group (PRP group, 22 patients). The VAS scores and WOMAC scores before treatment, 1, 3, 6 and 12 months after surgery were compared between the two groups to assess the knee joint function, and observed whether there were complications. Results Forty-three patients were followed up for 12 to 62 months after the operation. After treatment, the two groups had no complications such as wound infection, joint infection, or deep vein thrombosis. The preoperative VAS score and WOMAC score of the two groups were not significantly different (P>0.05);compared with those before the operation, VAS score and WOMAC score were significantly different at 1, 3, 6, and 12 months after the operation (P<0.05); compared with the control group, the VAS score of the PRP group was significantly reduced at 3, 6, and 12 months after surgery (P<0.05), and the WOMAC score of the PRP group was significantly improved at 6 and 12 months after surgery (P<0.05). The overall effective rates of the PRP group and the control group were 90.48% (19/21) and 77.27% (17/22) respectively, and the difference between the two groups was statistically significant (P<0.05). In the follow-up 12 months after the completion of the treatment, 6 patients in the control group and 2 patients in the PRP group underwent unicondylar replacement. Conclusion The combination of platelet-rich plasma and core decompression in the treatment of early SONK was safe and effective, and the clinical effect was better than that of core decompression only.
