OBJECTIVE To comparatively analyze tumor staging versus clinical staging in reimbursement scope restrictions under medical insurance for antineoplastic agents in order to better implement the medicare drug payment policy. METHODS Antineoplastic agents included in the National Basic Medical Insurance， Workers’ Compensation Insurance and Maternity Insurance Drug Catalogue （2024） （hereinafter referred to as the “Medical Insurance Catalog”） were used as research subject to compile and analyze reimbursement scope restrictions regarding tumor staging. By consulting clinical diagnosis and treatment guidelines and relevant literature， the tumor staging in reimbursement scope restrictions of the Medical Insurance Catalog was mapped and compared with clinical staging. RESULTS & CONCLUSIONS A total of 89 antineoplastic agents’ medical insurance payments had tumor staging. Among these， there were 86 western drugs （including 17 ordinary western drugs， 68 negotiated drugs， and 1 competitive drug） and 3 Chinese patent medicines （including 1 ordinary Chinese patent medicine and 2 negotiated drugs）. Non-small cell lung cancer involved the most restricted payment drugs， with 36 drugs. The tumor staging in reimbursement scope restrictions was mostly “metastatic” and “locally advanced”， involving 67 and 48 drugs respectively. Tumor staging in most reimbursement scope restrictions could correspond to the clinical staging of the tumor. However， mid-advanced esophageal cancer， unresectable gastrointestinal stromal tumors， unresectable locally advanced neuroendocrine tumors， locally advanced basal cell carcinoma， and unresectable neurofibromatosis type Ⅰ did not have a corresponding clinical staging mentioned in authoritative guidelines or high-quality clinical studies and need to be determined by the clinic according to the actual situation of the patient. Therefore， it is recommended that the interpretation of tumor staging in reimbursement scope restrictions should be accurately defined and standardized， so as to improve the accuracy of the drug payment policy in the actual implementation process.

Objective To evaluate the effectiveness of WeChat group integrating with BOPPPS instructional model in the standardized training of nurses in an orthopedics department.Methods A total of 56 nurses in orthopedical standardized training from a hospital were selected and divided into a control group(28 nurses from September 2022 to August 2023)and an interven-tion group(28 nurses trained via WeChat groups and the BOPPPS model from September 2023 to August 2024).The two groups were compared in terms of their final assessment scores,critical thinking,and self-directed learning capabilities.Results After training,the intervention group had significantly higher scores in the final assessment,all items of the California Critical Thinking Disposition Inventory,and all dimensions of the Learning Ability Assessment Scale compared to the control group(all P＜0.05).Conclusion WeChat groups combined with the BOPPPS teaching mode effectively improves the self-directed learning ability,critical thinking skills,and assessment results of orthopedic nurses.

Objective To investigate the effect of Scutellarin(Scu)regulating miR-26a-3p/Survivin molecular axis on myocardial ischemia/reperfusion injury(MIRI)in rats and its mechanism.Methods Fifty SD rats were randomly divided into sham group,model group,scutellarin group(Scu),miR-26a-3p agomir group(agomir)and scutellarin+miR-26a-3p agomir group(Scu+agomir)with 10 rats in each group.The animal model of MIRI was established by ligating the anterior descending coronary artery.The rats in each group were given 20 mg/kg Scu or 10 nmol agomir before and during operation,respectively,and the rats in sham group and model group were given the same amount of solvent.At 48 h after operation,the cardiac function of rats was examined by echocardiography.The pathological changes of myocardial tissue were detected by HE staining.The levels of myocardial injury markers creatine kinase isoenzyme MB(CK-MB),lactate dehydrogenase(LDH)and cardiac troponin I(cTnI)in serum and the contents of oxidative markers Malondialdehyde(MDA),superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)in myocardial tissue were detected by biochemical kit.The apoptosis of rat cardiomyocytes was detected by TUNEL staining.The mRNA expression levels of miR-26a-3p and Survivin in rat myocardium were detected by qRT-PCR.Expression levels of Survivin,cyclin-dependent kinase inhibitor(p21)and cleaved-caspase 3 were detected by Western blot.Results Compared with sham group,the pathological damage of myocardial tissue in the model group was serious,the levels of cardiac function LVEDP and serum CK-MB,LDH and cTnI significantly increased(P<0.01),and the levels of LVESP,LVEF and LVFS significantly decreased(P<0.01).The apoptosis level and MDA level of myocardial tissue significantly increased(P<0.01),while the SOD and GSH-Px levels significantly decreased(P<0.01).Meanwhile,the expression levels of miR-26a-3p and cleaved-caspase 3 protein significantly increased(P<0.01),the p21 protein and Survivin mRNA and protein expression levels significantly decreased(P<0.01).Compared with model group,the pathological injury of myocardium in Scu group was significantly improved,the levels of cardiac function LVEDP and serum CK-MB,LDH and cTnI significantly decreased(P<0.01),and the levels of LVESP,LVEF and LVFS significantly increased(P<0.01).The apoptosis level and MDA level of myocardial tissue significantly decreased(P<0.01),while the SOD and GSH-Px levels significantly increased(P<0.01).Meanwhile,the expression levels of miR-26a-3p and cleaved-caspase 3 protein significantly decreased(P<0.01),the p21 protein and Survivin mRNA and protein expression levels significantly increased(P<0.01).However,intervention with miR-26a-3p agomir could significantly reverse the improvement effect of Scu on MIRI in rats.Conclusion Scu can improve cardiac function and myocardial injury and inhibit myocardial cell apoptosis in MIRI rats,and its mechanism may be related to the regulation of miR-26a-3p/Survivin molecular axis.

Objective:To evaluate the safety and efficacy of digital technology-assisted debridement and bone and soft tissue reconstruction in the treatment of chronic osteomyelitis of the tibia.Methods:This retrospective study analyzed clinical data from 38 patients (26 males, 12 females; mean age 45.61±18.36 years, range 16-83 years) with chronic post-traumatic osteomyelitis complicated by soft tissue defects in the tibia, treated at the Department of Orthopaedics, Fourth Medical Center of PLA General Hospital between June 2021 and June 2023. There were 18 cases of traffic accidents, 6 cases of high-altitude falls, 6 cases of heavy objects and 6 cases of low-energy falls. Lesion sites: 12 cases in the upper segment of the tibia, 12 cases in the middle segment, and 14 cases in the lower segment. According to the Cierny-Mader classification, there were 24 cases of type III and 14 cases of type IV. Before the operation, the "3D point cloud technology" was used to plan the debridement range of bone and soft tissue. During the operation, the optical navigation system was used to monitor the debridement range in real time. The flap was designed by combining "Reading Tablet Treasure" with CT angiography, and the amount of bone graft was predicted by AI algorithm. The surgical method adopted is the Masquelet technique, namely thorough debridement, bone cement occupation and soft tissue repair in the first stage, and bone reconstruction in the second stage. Comparing the calculated bone defect amount and soft tissue defect area before the operation with the actual measured values after debridement. The cure rate of infection was evaluated by using the McKee bone infection treatment criteria after the operation. The visual analogue scale (VAS) for pain, lower extremity functional scale (LEFS), and self-rating anxiety scale (SAS) were used to evaluate the improvement of the quality of life of postoperative patients.Results:38 patients were followed up with a mean follow-up of 13.53±2.37 months. 37 patients' infections were effectively controlled, and 1 patient had a recurrence of infection, with an effectiveness rate of 97% for the treatment of McKee's infections. The preoperative calculated bone defect amount and soft tissue defect area were 51.05±26.31 cm 3 and 68.42±43.45 cm 2 respectively, and the actual measured values after debridement during the operation were 51.66±26.35 cm 3 and 68.82±43.76 cm 2 respectively. There was no statistically significant difference before and after the operation ( P>0.05). The interval between the first and second stage surgeries was 10.36±1.61 weeks, and all flaps survived after the first stage surgery. Two months after the operation, one case had recurrent osteomyelitis. After palliative treatment, sinus tracts were formed at the infection site. At the 12-month regular dressing change follow-up, there were still purulent secretions in the sinus tracts. There was no recurrence of infection after primary debridement in 37 cases, and the bone grafts healed. The bone healing time was 3.58±0.97 months. The postoperative VAS, LEFS, and SAS scores were 1.00±0.91, 66.68±7.91, and 34.30±4.29, respectively, which were significantly improved compared with the preoperative scores of 7.54±1.52, 21.22±4.29, and 52.70±6.74, respectively, and the difference was statistically significant ( P<0.05). Conclusions:The application of digital technology to precisely design the debridement range of bone and soft tissue, and the real-time holographic visualization monitoring of the debridement range during the operation can achieve precise debridement of bone and soft tissue and personalized and precise repair of soft tissue defects. It is a safe and effective technique for the treatment of chronic osteomyelitis of the tibia.
