Usage: Subjects started fasting for solid from 21:00 on the day before the study and for liquid within 1 h before and after the administration. Subjects in each dose group received a single administration on the first day of the study on an empty stomach. Blood samples were collected at different time points before and within 48 hours after the administration (before the administration on day 3). No administration was conducted on day 2. continuous administration was conducted from day 3 to day 8, twice a day, once in the morning on an empty stomach, once in 12 hours (±15min). The valley concentration blood samples were collected in the morning on day 6, 7 and 8. In the morning of day 9, a single administration was conducted on an empty stomach. Blood samples were taken at the different time points before and within 48 hours after the administration on day 9. Each dose was taken with 240 mL warm water.Except for the water taken together with the tablets, it should be ensured that the water was banned for 1 hour before and after the valley concentration blood sample collection from day 6 to day 8 and 1 hour before and after the administration in the morning on day 1 and day 9. 6.

Statistics: - Pharmacokinetic analysis: Phoenix WinNonlin software (Pharsight Corporation, version 7.0) was used to estimate and analyze the parameters of PK in non-atrioventricular model according to dosage. The pharmacokinetic parameters were calculated in real time to fully reflect the characteristics of drug absorption, distribution, metabolism and excretion in human body. The PK parameters of each participant were calculated according to the following methods. PK parameters include: AUC0-t, AUC0-∞, Cmax, Tmax, t1/2, CL/F, Vd/F, MRT, λz, Css_av, Css_min, Css_max, Accumulation rate and Fluctuation index. Descriptive statistics were summarized on untransformed datas of drug concentration in plasma at each time point: AUC0 t, AUC0-∞, Cmax, Tmax, t1/2, CL/F, Vd/F, MRTλz, Css_av, Css_min, Css_max, R and DF. Descriptive statistics was used in the analysis of Number (N), arithmetic mean, geometric mean, standard deviation (SD), CV, minimum, median and maximum. Average and individual time-concentration curves were drawn according to the study group. • Safety analysis All AE, treatment emergent adverse events (TEAE), drug-related TEAE, grade 3 or above TEAE, serious adverse events (SAE), drug-related SAE, TEAE leading to death, TEAE leading to termination of trial, drug-relation TEAE leading to termination of trial and drug-related TEAE leading to discontinuation of use of test drug were summarized for case number, subject number and incidence rate. P value for the incidence of these AEs with different classifications was calculated by Fisher's exact test. TEAE, SAE, drug-related TEAE, drug-related SAE, TEAE leading to the termination of the trial, and TEAE leading to the discontinuation of drug use were summarized and described according to the system organ classification (SOC), preferred terminology (PT) and study group. The severity of TEAE and drug-related TEAE was also summarized according to SOC, PT and study groups. The measured value of parameters and changes from baseline of vital signs, 12-lead ECG, physical examination, clinical laboratory examination, etc. were summarized according to the planned time point and the study group. Determine dose-limited toxicity of multiple dose in human (DLT); Determine the maximum tolerable dose of multiple dose in human (MTD).
