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.

Adjuvant radiotherapy (RT) can improve the rate of loco-regional control for patients with gastric cancer (GC),while the selection of patients plays a key role.As the research moves along,several relatively comprehensive molecular classifications emerged such as the TCGA classification and the ACRG classification.Studies have demonstrated that molecular classifications are closely related to the clinicopathologic characteristics,prognosis and treatment response.However,there is not recognized molecular classification of GC presently.It is a great challenge for radiation oncologists to make use of the individual bioinformation and accurately select patients who would benefit from RT.Meanwhile,precision RT could also be achieved with the prediction of radiosensitivity,combination of RT with targeted therapy and the application of ctDNA within the field of RT.
