Larotaxel, a new taxane compound prepared by partial synthesis from 10-deacetyl baccatin Ⅲ, is active against tumors. In this research, a selective LC–MS method was developed and validated for the study of degradation kinetics of larotaxel, which was carried out in aqueous solutions with different pH (1.5, 3.0, 5.0, 6.5, 7.4, 9.0, 10 and 11.0) and temperature (0, 25, 37 and 45 °C). The linear range was 0.5–25μg/mL, the intra-and inter-day precisions were less than 7.0%, and accuracy ranged from 97.4–104.5% for each analyte. The observed rate obtained by measuring the remaining intact larotaxel was shown to follow first-order kinetics. The activation energies for degradation were 126.7 and 87.01 kJ/mol at pH 1.5 and 11, respectively. Although larotaxel was stable in pH 5, 6.5 and 7.4 buffers at 37 °C for 24 h during our study, increasing or decreasing the pH of the solutions would decrease its stabilities. Moreover, three main degradation products in alkaline condition were separated by HPLC and identified by Q–TOF–MS. The three degradation products were confirmed as 10-deacetyl larotaxel, 7, 8-cyclopropyl baccatin Ⅲ and 10-deacetyl-7, 8-cyclopropyl baccatin Ⅲ.

Objective : To explore whether miR⁃9 affects the proliferation of neural stem cells (NSCs) by regulating β ⁃tubulin Ⅲ and glial fibrillary acidic protein (GFAP) . Methods : NSCs cells were isolated and cultured on the purchased healthy pregnant mice and the isolated cells were divided into NO group ( non⁃transfected NSCs cell line) , NN group (NSCs transfected with miR⁃9 ⁃NC) , NM group (NSCs transfected) transfected with miR⁃9 mimics) , NI group ( transfected with miR⁃9 inhibitor) . Nestin was identified by immunofluorescence , the contents of Mir⁃9 , β ⁃tubulin Ⅲ and GFAP were measured by QRT⁃PCR , the proliferation of NSCs was measured by MTT method , the apoptosis of NSCs was measured by flow cytometry , and the protein expressions of Mir⁃9 , β ⁃tubulin Ⅲ and GFAP were detected by Western blot. Results : The detection index Nestin of NSCs for 24 h after cell passage was positive in 90% of the NSCs , and co⁃localized with the nucleus , indicating the successful isolation of NSCs. The expression of miR⁃9 mRNA in NSCs of the NM group was the highest among the four groups , indicating that the transfection was successful. Among the four groups , β ⁃tubulin Ⅲ mRNA and protein expression was the highest in the NM group , and the GFAP mRNA and protein expression was the lowest. The NI group was the opposite (P < 0. 05) . In the four groups after 24 h , the cell activity of NSCs in the NM group was the strongest and showed a trend of gradually increasing with time (P < 0. 05) . The cell activity of NI was significantly weaker than that of the other three groups (P < 0. 05) . Among the four groups , the apoptosis rate of the NM group was lower than that of the other three groups (P < 0. 05) , and the apoptosis rate of NI was higher than that of the other three groups (P < 0. 05) . The difference in the above indicators between the NO group and the NN group was smaller. Conclusion Overexpressed miR⁃9 promotes the proliferation of NSCs by promoting the expression of β ⁃tubulin Ⅲ and inhibiting the expression of GFAP.

【Objective】 To explore the model of treatment of refractory wounds by apheresis platelet-rich plasma (PRP), and evaluate its efficacy and safety. 【Methods】 PRP treatment was carried out for 34 patients with refractory wounds who were hospitalized in our hospital from June 2020 to December 2023. The patient′s autologous PRP was collected by the blood composition separator. PRP point-like injection and/or direct application along the edge of the wound, or platelet gel (PG) to cover the wound and fill the sinus were used to treat different types of wounds. The frequency of treatment was once to twice a week, with each course of treatment consisting of 4 to 5 sessions. The efficacy was observed and recorded, and the safety was evaluated. 【Results】 Before PRP collection, the basal platelet, white blood cell and red blood cell counts were (321.85±114.64) ×10⁹/L, (9.52±3.21) ×10⁹/L and (4.34±0.62) ×10¹²/L, respectively. The counts of platelets, white blood cells and red blood cells in PRP products were (1 438.53±376.89)×10⁹/L, (1.38±1.03)×10⁹/L and (0.03±0.01)×10¹²/L, respectively. The platelet concentration of PRP products increased by 4.47 times on average, and the sampled bacterial culture was negative. Out of 34 patients treated with PRP, 33 showed improvement in symptoms, while 1 did not respond well due to long-term bedridden and poor compliance. Four patients had mild adverse reactions during PRP collection or treatment, but all were able to complete PRP collection or treatment after standardized treatment. 【Conclusion】 Apheresis PRP products have the advantages of stable quality, safety, reliability and traceability, and can effectively promote the healing of a variety of refractory wounds. Its treatment process is safe and effective, and is worthy of popularization and application.
