Baicalein-nicotinamide(BE-NCT)co-crystal was chosen as model drug to investigate the thermody-namic characteristics.Solubilities of BE in NCT solutions in ethyl acetate at different temperatures were deter-mined in order to explain the complexation behavior of BE-NCT co-crystal.Thermodynamic parameters of co-crys-tal formation progress were calculated.Ternary phase diagrams (TPDs)of the BE-NCT-ethyl acetate systems at various temperatures were established.The non-linear fitting equation according to 1 ∶1 complexation mechanism of BE-NCT co-crystal demonstrated a good correlation between calculated and experimental data (R2 >0.98). Co-crystal formation is a spontaneous process(ΔG°<0).Increase in temperature resulted in the increase of Ksp;decrease of K11 and a narrowed co-crystal zone.The degree of spontaneous reaction also decreased with increased temperature.The spontaneous reaction no longer carried out if the temperature reached T* =315 K sinceΔG°=0(ΔH°=-6.314 ×10 -2 kJ/mol;ΔS°=-0.200 5 J/mol.K).A drop in temperature favors the complexation between BE and NCT in ethyl acetate.Since NCT has higher solubility than BE in ethyl acetate;the TPDs of co-crystal was asymmetric.The DSC diagrams of products prepared via three presupposed methods confirmed that the BE-NCT co-crystal could be generated in solutions of nonstoichiometric compositions.

Objective:To explore the effects of myosteatosis and blood glucose (BG) on postoperative complications in non-diabetic gastric cancer patients receiving supplemental parenteral nutrition (SPN) after gastrectomy.Methods:Patients who underwent radical gastrectomy between March 2017 and June 2021 in the Department of Surgical Oncology, the First Hospital of Lanzhou University were included in this study. Various preoperative inflammatory and nutritional indicators, including skeletal muscle metrics at the third lumbar level on CT, were collected retrospectively. Postoperative BG within 3 days and complications within 30 days were monitored. Patients were divided into two groups according to the presence or absence of myosteatosis (assessed via skeletal muscle density [SMD]) and the differences in postoperative BG and complication incidence were compared. Mediation model was used to analyze the mediating effect of BG in the association between SMD and postoperative complications.Results:A total of 357 patients were included in the study. Compared with the 299(83.8%) patients without myosteatosis , the incidence of hyperglycemia, mean BG, maximal BG, and BG fluctuation while on SPN in the 58(16.2%) patients with myosteatosis were higher, and the comprehensive complication index (CCI) and the incidence of complication were higher ( P<0.05). More importantly, BG showed the mediation effect of -0.0892 in the effect of SMD on CCI ( P<0.05), with the effect size of 19.3%. Conclusion:Myosteatosis and postoperative hyperglycemia are associated with higher incidence of complications, and BG plays an intermediary role in the association between myosteatosis and CCI.

Objective:To explore the mechanism of miR-205-5p/E2F1 signal axis in regulating the glioma U251, U87 radiotherapy resistance.Methods:X-ray gradual ascending and intermittent induction method was used to irradiate the glioma U251 cells to establish U251/TR, U87/TR radiation-resistant cell lines. Then, the morphology, migration, invasion and proliferation abilities of cells (U251/TR, U87/TR radiation-resistant cells and U251, U87 radiation-sensitive cells) were analyzed. Luciferase gene detection system and point mutation technique were employed to analyze the mechanism of miR-205-5p and E2F1 gene activity on U251 and U87 radiation-resistant cell lines.Results:Compared with the radiation-sensitive U251 cells, the radiation-resistant cells U251/TR, U87/TR showed increased proliferation activity, enhanced migration and invasion abilities and decreased apoptosis under X-ray irradiation. miR-205-5p mimics transfection could down-regulate the expression of E2F1 factor in U251/TR cells, inhibit cell proliferation, invasion and migration and increase the radiosensitivity of U251/TR cells. miR-205-5p mimics transfection combined with with E2F1 down-regulation exerted anti-tumor effect and decreased cell tolerance by suppressing the Wnt/β-catenin signaling pathway activity.Conclusions:The glioma radiation-resistant cell line U251/TR, U87/TR can be established by X-ray gradual ascending and intermittent induction method. The miR-205-5p/E2F1 signal axis exerts tumor-suppressing effect through the classical Wnt/β-catenin signaling pathway, which can be used as an therapeutic target to increase the radiosensitivity of glioma.
