Objective:To explore the clinical feasibility and effectiveness of using 3D printed porous titanium-alloy prosthesis to repair aseptic large bone defects in the limbs.Methods:A retrospective analysis was performed on 13 patients with aseptic bone defects of long limbs treated with 3D printed porous titanium alloy prosthesis from December 2017 to December 2022, including 7 males and 6 females, aged 52.6±11.5 years (range, 35-72 years). The bone defect locations included 2 humerus, 1 radius, 5 femur, and 6 tibia. One patient suffered both femoral and tibial defects. All 13 patients suffered from bone nonunion due to internal fixation surgery, including 5 cases of hypertrophic nonunion and 8 cases of atrophic nonunion. The interval between internal fixation surgery and this treatment was 20.1±3.6 months (range, 16.5-26.6 months). The clinical treatment effect was evaluated through parameters such as gross observation, imaging evaluation, disability of arm shoulder and hand (DASH), lower extremity functional scale (LEFS), and patient satisfaction evaluation.Results:The length of bone defect after debridement in 13 patients was 11.7±4.5 cm (range, 6.0-20.6 cm), and the length of implant was 12.9±5.3 cm (range, 6.1-22.9 cm). Partial or complete weight-bearing began at 14.8±6.5 days (range, 2-22 days) after surgery. All 13 cases were followed up for 18.3±12.5 months (range, 13-58 months). The X-ray images showed that the prosthesis and the internal fixation were stable, and the new bone gradually grew gradually from the bone defect section and formed stable bone integration with the prosthesis surface, and no prosthesis displacement or fracture occurred. At the last follow-up, the DASH scores of 3 patients with upper limb bone defect were 8.9, 10.5, and 11.2 points, respectively, and the LEFS scores of 10 patients with lower limb bone defect were 49.6±5.9 points (range, 38-56 points). No significant subsidence or loosening of all prosthetics was observed. Patient satisfaction was 9.8±0.1 points (range, 9.6-9.9).Conclusion:After the application of 3D printed porous titanium alloy prosthesis to repair the aseptic large bone defect of the limbs, the patients can carry weight and function exercise in the early stage, and the function of the affected limbs can recover significantly, and the patients have high satisfaction.

BACKGROUND: Studying the relationship between flexibility and body composition of college students is of great significance for enhancing the levels of physical health and sports. OBJECTIVE: To investigate the relationship between sit-and-reach and body composition of college students in Guangxi Zhuang Autonomous Region and differences between sexes. METHODS: Totally 2 175 students from a Guangxi university were randomly selected. Body composition was determined by the MC-180 body composition tester. The students were divided into four groups: ≤ 12.10 cm group,> 12.10-16.40 cm group,> 16.40-20.70 group and> 20.70 group according to quartile of sit-and-reach measured in accordance with the National Physical Health Test Standard. All data were processed by SPSS 22.0 software. RESULTS AND CONCLUSION: Sit-and-reach was significantly correlated with body mass index, percentage of body fat, fat-free mass index, upper limb lean mass and lower limb lean mass (P < 0.05), and percentage of body fat was negatively correlated with sit-and-reach (P < 0.05). The body mass index, fat-free mass index, upper limb lean mass and lower limb lean mass in the ≤ 12.10 cm group were significantly lower than those in the other groups. Fat-free mass index and upper limb lean mass were correlated with sit-and-reach in male college students (P < 0.05). The fat-free mass index and upper limb lean mass in the> 16.40-20.70 cm group were significantly higher than those in the ≤ 12.10 cm group. Therefore, there is a positive correlation between the flexibility and fat-free mass index and upper limb lean mass in college students.

Objective:To analyze and summarize the clinical effects of 3D printed porous titanium-alloy prosthesis implantation in the treatment of long bone defects of lower extremities.Methods:We retrospectively studied the clinical cases with lower extremity bone defect treated by 3D printed porous titanium prostheses from December 2017 to November 2021. 18 patients who were followed up for more than 12 months were included in this study. The enrolled patients included 12 males and 6 females, with an average of 48.9±22.5 years (range, 13-79 years), and an average body mass index of 23.1±4.3 kg/m 2 (range, 17.2-27.1 kg/m 2). There were 14 osteomyelitis-derived bone defects and 4 nonunion-derived bone defects. The bone defect locations included 10 cases of femur and 8 cases of tibia. The average bone defect distance was 13.9±9.7 cm (range, 5.8-31.2 cm), and the proportion of the defect length to the long bone (femur of tibia) was average 33.7%±16.8% (range, 15.0%-63.0%). The clinical efficacy was comprehensively evaluated through gross observation, imaging evaluation, changes in the total length of lower extremities and long bones, femorotibial angle (FTA) measurement, lower extremity functional scale (LEFS), satisfaction, complications and other indicators, focusing on the stabilization mechanism of the prosthesis and the regeneration of new bone. Results:All 18 patients were followed up for 12-35 months, with an average of 16.3 months. Postoperative X-rays at 1, 3, 12 and 24 months showed that new bone could gradually creep along the prosthesis surface. The preoperative bone defect length of long bone and total length of lower limb were respectively 39.4±4.0 cm and 80.5±5.7 cm, which were different from those of the healthy side by 1.6±1.0 cm and 1.5±1.1 cm. One week after implantation, the length of long bone and lower limb was 39.9±3.5 cm and 80.9±6.2 cm, respectively, and the average difference was 1.0±0.6 cm and 0.9±1.1 cm compared with the healthy side. At the last follow-up, the length of long bone and lower limb was 39.7±3.6 cm and 80.9±7.8 cm, with an average difference of 1.8±1.1 cm and 1.0±0.7 cm from the healthy side. There were no significant differences in the length of long bone and lower limbs at the three time points before surgery, one week after surgery and the last follow-up ( F=0.12, 0.04; P>0.05). The average FTA of the affected limb was 174.7° (173.9°, 175.5°), 175.2°(173.5°, 176.4°), and 175.0°(173.5°, 176.3°) at three time nodes, before surgery, one week after surgery and the last follow-up, respectively, and there was no significant statistical difference in pairwise comparison ( Z=0.01, P>0.05). Patients had a mean LEFS score of 50 (46, 51) at the last follow-up, significantly higher than the preoperative score of 20 (17, 21) ( Z=-5.56, P<0.001). The mean satisfaction score of the 18 patients at the last follow-up was 9.7. Two patients (11.1%) had screw fractures but all 3D printed porous titanium alloy prostheses remained stable without significant loosening or displacement. Two patients (11.1%) had nail channel infection of external fixator, all patients with channel infection were cured by intravenous antibiotics combined with local disinfection and dressing change. Conclusion:The implantation of 3D printed porous titanium-alloy prosthesis could efficiently and safely repair the long bone defects of the lower extremities. The prosthesis could maintain stable in the early and middle postoperative period. The length of the long bones and lower limbs did not change significantly with the weight-bearing and functional exercise of the limbs. The new bone could gradually crawl and grow from both ends of the defect, and the patient's limb function recovered significantly, and the patient's satisfaction was high.

Central nervous system (CNS) injuries, including stroke, traumatic brain injury, and spinal cord injury, are essential causes of death and long-term disability and are difficult to cure, mainly due to the limited neuron regeneration and the glial scar formation. Herein, we apply extracellular vesicles (EVs) secreted by M2 microglia to improve the differentiation of neural stem cells (NSCs) at the injured site, and simultaneously modify them with the injured vascular targeting peptide (DA7R) and the stem cell recruiting factor (SDF-1) on their surface via copper-free click chemistry to recruit NSCs, inducing their neuronal differentiation, and serving as the nanocarriers at the injured site (Dual-EV). Results prove that the Dual-EV could target human umbilical vascular endothelial cells (HUVECs), recruit NSCs, and promote the neuronal differentiation of NSCs in vitro. Furthermore, 10 miRNAs are found to be upregulated in Dual-M2-EVs compared to Dual-M0-EVs via bioinformatic analysis, and further NSC differentiation experiment by flow cytometry reveals that among these miRNAs, miR30b-3p, miR-222-3p, miR-129-5p, and miR-155-5p may exert effect of inducing NSC to differentiate into neurons. In vivo experiments show that Dual-EV nanocarriers achieve improved accumulation in the ischemic area of stroke model mice, potentiate NSCs recruitment, and increase neurogenesis. This work provides new insights for the treatment of neuronal regeneration after CNS injuries as well as endogenous stem cells, and the click chemistry EV/peptide/chemokine and related nanocarriers for improving human health.
