Abstract
BACKGROUND The adhesion and survival state of cells on scaffold material is a major problem in tissue-engineered blood vessel (TEBV) culture. Platelet-rich plasma (PRP) contains a large amount of biologically active factors and fibrin, which is expected to play an important role in TEBV culture. PURPOSE To combine PRP with cells and scaffold material to promote cell adhesion and biological activity on the scaffold material. METHODS The adhesion status and migration of SMCs under the optimal concentration suitable for SMC growth and the optimal concentration of PRP were examined by scanning electron microscopy, HE staining, CCK-8 assays, qPCR, WB, and other experimental methods and compared with those under the conventional culture (20% FBS); finally, the effect of PRP on the deposition of ECM in vascular tissue engineering culture was verified by three-dimensional culture. RESULTS PRP at 20% is a suitable concentration for SMCs. Compared with the control group, the 20% PRP group had better migration, and the number of SMC adhesions was significantly higher than that of the control group. In addition, collagen deposition in the experimental group was significantly higher than that in the control group. CONCLUSION PRP (20%) can promote SMC adhesion, migration, and collagen deposition on the scaffold material.

Abstract
OBJECTIVE To explore correlations between the therapeutic effect of high intensity focused ultrasound (HIFU) and histopathological characteristics of uterine fibroids with different Shear Wave Velocity (SWV) values. METHODS A retrospective study was conducted on 36 women (43 fibroids) who had undergone high intensity focused ultrasound (HIFU) uterine fibroids ablation between January 2019 and January 2020. Preoperative fibroids tissue sections were obtained for histopathological examination. The pathological sections were stained with Masson-trichrome, and were observed and imaged under a Low-power microscope (4 × 10), while the smooth muscle cell (SMC) and collagen fiber content were semi-quantitatively measured. Preoperative fibroid SWV was measured using the Virtual Touch tissue quantification (VTQ) technique. Within one month after HIFU ablation, all patients had undergone a pelvic cavity MRI examination, which measured the size, volume, and non-perfused volume (NPV) of the fibroids. The formula: the ablation rate = NPV/target fibroid volume × 100% was used to calculate the ablation rate of the uterine fibroids. Correlation analysis of SWV values, HIFU ablation rate, along with the smooth muscle cell (SMC) and collagen fiber content, were conducted using the Spearman's correlation test. RESULTS The collagen fiber and SMC content of the preoperative fibroids were 32.09 ± 15.90%/view and 37.61 ± 15.32%/view, respectively. Preoperative fibroid SWV value was 3.56 ± 0.71 m/s. Preoperative fibroid SWV was negatively correlated with SMC content (r = -0.445, p = 0.003), but positively correlated with collagen fiber content (r = 0.454, p = 0.002). The ablation rate was negatively correlated with collagen fiber content (r = -0.377, p = 0.013), but positively correlated with SMC content (r = 0.402, p = 0.007). CONCLUSION Differences in histopathological characteristics may be important factors that induce differences in the therapeutic effects of HIFU ablation on uterine fibroids with different SWV values.

Abstract
Previous investigations have demonstrated that TiO2 nanotubes (NTs) with particular structure cues could control the behavior of different types of cells, including endothelial cells (ECs) and smooth muscle cells (SMCs). Besides, polydopamine (PDA) modified surfaces were reported to be beneficial to increase the proliferation and viability of ECs and meanwhile could inhibit the proliferation of SMCs. The TiO2 nanotubes (NTs) were functionalized with polydopamine (PDA) (PDA/NTs) to study the synergetic effect of both nanotopography (NTs) and chemical cues (PDA) of TiO2 nanotubes on the regulation of cellular behavior of ECs and SMCs. The PDA-modified TiO2 nanotubes were subjected to field-emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), and water contact angle (WCA) analysis. In vitro cell culture tests confirmed that, comparing with flat titanium (Ti) and TiO2 nanotubes, PDA/NTs surface synergistically promoted ECs attachment, proliferation, migration and release of nitric oxide (NO). Meanwhile, the PDA/NTs performed well in reducing SMCs adhesion and proliferation. This novel approach might provide a new platform to investigate the synergistic effect of local chemistry and topography, as well as the applications for the development of titanium-based implants for enhanced endothelialization.
