Brief summary: This is a Phase I, open-label, non-randomized, dose-escalation study to evaluate the safety and tolerability, the maximum tolerated dose (MTD) and the dose limited toxicity(DLT) of LY01610 monotherapy and combine with 5-Fu in patients with advanced solid tumors. Additionally, the pharmacokinetics and preliminary efficacy of LY01610 monotherapy and combine with 5-Fu will be investigated in this study.

Detailed description: This study will be conducted in two stages: In the first stage, ascending doses of LY01610 will be administered as monotherapy in participants with solid tumors. The starting dose was 30 mg/m2 and the subsequent dose was increased according to the protocol of 60 mg/m2, 90 mg/m2, 120 mg/m2, 150 mg/m2, 180mg/m2. Each subject received only one dose of the drug, and the next dose group study could only be performed if the previous dose group was completed 21 days of observation after the first dose and safe tolerance was confirmed. According to the subjects' tolerance, appropriate doses will be selected and the safety, PK characteristics and initial efficacy of LY01610 were further evaluated in additional 6 - 8 patients. The interval between the first dose and the second dose was 3 weeks, followed by 2 weeks.Another 8 subjects were enrolled and given CAMPTO® (180 mg/m2) once every 2 weeks to perform the pharmacokinetic profiles.

The second stage is a dose escalation study of LY01610 combined with 5-Fu. Based on the results of the first stage, three doses of low, medium and high doses were selected in combination with a fixed dose of 5-Fu to determine the DLT and MTD. Similarly, according to the subjects' tolerance, appropriate dose will be selected and the safety, PK characteristics and initial efficacy of LY01610 combined with a fixed dose of 5-Fu were further evaluated in 6 - 8 patients. The drug was administered every 2 weeks.

Eligibility criteria: Inclusion Criteria:

* Male or female patients aged 18 to 70 years (18 years and 70 years are inclusive).
* Histologically or cytologically confirmed solid tumor for which failed or could not •tolerate standard treatment, or standard effective treatment does not exist.

* The female subjects of childbearing age and male subjects with fertility potential female partner agree to take reliable contraceptive measures (such as abstinence, sterilizing operation, contraceptives, injection of the contraceptive drug •medroxyprogesterone acetate or subdermal implant of contraceptives) during the study period and within 6 months after infusion of the study drugs.

Exclusion Criteria:

* The patient with hepatitis B surface antigen (HBsAg) positive and the peripheral blood HBV DNA titer ≥1× 103 copies/mL or 200 IU/ml The subject is eligible to be enrolled if HBsAg is positive and peripheral blood hepatitis B virus (HBV) DNA titer \<1×103 copies/ml or 200 IU/ml and the investigator considers that the subject is at the stable stage of chronic hepatitis and the risk will not be increased for the subjects;the patient with hepatitis C virus (HCV) antibody and human immunodeficiency virus (HIV) antibody positive;
* Patients still with clinically significant electrolyte disorders that were diagnosed by the investigator before drug administration;
