In recent years, there has been significant research progress on in situ articular cartilage (AC) tissue engineering with endogenous stem cells, which uses biological materials or bioactive factors to improve the regeneration microenvironment and recruit more endogenous stem cells from the joint cavity to the defect area to promote cartilage regeneration.In this study, we used ECM alone as a bioink in low-temperature deposition manufacturing (LDM) 3D printing and then successfully fabricated a hierarchical porous ECM scaffold incorporating GDF-5.Comparative in vitro experiments showed that the 7% ECM scaffolds had the best biocompatibility. After the addition of GDF-5 protein, the ECM scaffolds significantly improved bone marrow mesenchymal stem cell (BMSC) migration and chondrogenic differentiation. Most importantly, the in vivo results showed that the ECM/GDF-5 scaffold significantly enhanced in situ cartilage repair.In conclusion, this study reports the construction of a new scaffold based on the concept of in situ regeneration, and we believe that our findings will provide a new treatment strategy for AC defect repair.

Background: Postpartum subinvolution of the uterus is a more common condition after cesarean section. Auricular acupressure (AA) is widely used for the treatment of postpartum diseases. However, few studies have explored the effects of AA as a treatment of uterine involution following cesarean section to date. This study aimed to assess the efficacy and safety of AA for uterine involution after cesarean section. Methods: A total of 109 women who underwent cesarean section participated in this study. They were randomly allocated to either real AA or sham AA in a 1:1 ratio by a computer program. For 3 days, the real AA and sham AA groups received treatment 3 times daily. A series of assessments at 42 days after cesarean section, namely on the uterine size, the incidence of hydrometra, the first anal exsufflation time, bleeding volume at 6 hours, bleeding volume at 6–24 hours along with other general assessments were carried out. Results: A total of 89 women completed the study. The uterine size at 42 days after a cesarean section was 6.3 cm smaller in the real AA group than in the sham AA group (P < 0.01). The incidence of hydrometra on day 42 postpartum was lower in the real AA group than in the sham AA group (P < 0.01). The lochia duration and the first anal exsufflation time after cesarean section were shorter in the real AA group than in the sham AA group (P < 0.05). Conclusion: AA improves uterine involution after cesarean section. Trial registration: ChiCTR1800015569.
