BACKGROUND:It has been confirmed that basic fibroblast growth factor (bFGF) can promote the growth, proliferation, differentiation and functional expression of most cels derived from neuroderm and mesoderm. OBJECTIVE:To investigate the effect of bFGF-transfected bone marrow mesenchymal stem cel transplantation in rats with acute kidney injury. METHODS: bFGF genes were transfected into bone marrow mesenchymal stem cels via an adenovirus vector, and then expression of bFGF in transfected cels was identified using RT-PCR technology. Rat models of acute kidney injury were prepared by clipping bilateral renal pedicles, and then randomized into three groups (n=20): rats were given injection of bone marrow mesenchymal stem cel suspensionsvia tail vein as negative transfected group, those given injection of bFGF-transfected bone marrow mesenchymal stem cel suspensionsvia tail vein as bFGF-transfected group, and the others given injection of DMEMvia tail vein as model group. Four weeks later, levels of serum creatinine and urea nitrogen were detected, expressions of connective tissue growth factor and growth factor in renal tissues were detected by Western blot assay, and morphology of renal tissues was observed using hematoxylin-eosin staining. RESULTS AND CONCLUSION:bFGF genes were successfuly transfected into bone marrow mesenchymal stem cels. Compared with the model group, the levels of serum creatinine and urea nitrogen were significantly reduced in bFGF-transfected and negative transfected groups, especialy in the bFGF-transfected group (P < 0.05), while expressions of connective tissue growth factor and transforming growth factor in renal tissues in bFGF-transfected and negative transfected groups were significantly weakened in these two groups (P < 0.05), but there were no significant differences between the bFGF-transfected group and negative transfected group (P > 0.05). Besides, renal tissues necrosis and inflammatory reactions were mitigated in the negative transfected group; renal tubules with normal outlines and no overt necrotic cels could be found in the bFGF-transfected group. These findings show that bFGF-transfected bone marrow mesenchymal stem cel transplantation plays a better role in acute kidney injury repair in rats.

Traditional Chinese medicines have demonstrated clinical efficacy in preventing and treating chemotherapy-induced peripheral neuropathic pain(CIPNP).However,their specific clinical application and mechanism of action require further in-depth study and exploration.There is thus a need to develop more accurate and clinically relevant animal models that reflect the occurrence and development of human diseases as a tool for research.This review provides an in-depth analysis and discussion of the recent establishment and detection criteria of existing rat and mouse animal models of paclitaxel-induced peripheral neuropathic pain.We also evaluate and explain the application of these models for the prevention and treatment of CIPNP in traditional Chinese medicine,thus providing a theoretical basis and reference for future experimental and mechanistic research on the subject.This research will benefit clinical practice and promotion,offering valuable insights into preventing and treating CIPNP using traditional Chinese medicines.
