Objective The effect of the functionally unknown gene C6orf120 on autoimmune hepatitis was investigated on C6orf120 knockout rats(C6orf120-/-)and THP-1 cells. Method Six-eight-week-old C6orf120-/-and wild-type(WT)SD rats were injected with Con A(16 mg/kg),and euthanized after 24 h.The sera,livers,and spleens were collected.THP-1 cells and the recombinant protein(rC6ORF120)were used to explore the mechanism in vitro.The frequency of M1 and M2 macrophages was analyzed using flow cytometry.Western blotting and PCR were used to detect macrophage polarization-associated factors. Results C6orf120 knockout attenuated Con A-induced autoimmune hepatitis.Flow cytometry indicated that the proportion of CD68+CD86+M1 macrophages from the liver and spleen in the C6orf120-/-rats decreased.C6orf120 knockout induced downregulation of CD86 protein and the mRNA levels of related inflammatory factors TNF-α,IL-1β,and IL-6 in the liver.C6orf120 knockout did not affect the polarization of THP-1 cells.However,rC6ORF120 promoted the THP-1 cells toward CD68+CD80+M1 macrophages and inhibited the CD68+CD206+M2 phenotype. Conclusion C6orf120 knockout alleviates Con A-induced autoimmune hepatitis by inhibiting macrophage polarization toward M1 macrophages and reducing the expression of related inflammatory factors in C6orf120-/-rats.

Progesterone is currently the first-line drug for clinical treatment and prevention of threatened abortion and habitual abortion. However, due to its special chemical structure, its solubility is low, which limits its clinical application. Therefore, the new technology and new dosage form of progesterone solubilization preparation is an important direction of its research and development. In this paper, the research progress of progesterone solubilization preparation technology in recent years is reviewed. It is found that the water solubility of progesterone can be enhanced by solid dispersion technology, inclusion technology, micronization, nanocrystallization ( including nanosuspensions, polymer micelles, nanoparticles, etc. ), liposome technology, self- emulsification, cocrystal technology, and 3D printing. Eight technologies are used to increase the solubility of progesterone, improve its bioavailability and reduce its toxic and side effects, to serve the clinic better.
