- Evaluation of platelet response (Complete Response) [ Time Frame: The time frame is up to 3 months per subject ] [ Designated as safety issue: Yes ]CR. A complete response (CR) was defined as a sustained (≥ 3 months) platelet count ≥ 100×10^9/L without recurrence of thrombocytopenia
- Evaluation of platelet response (R) [ Time Frame: The time frame is up to 3 months per subject ] [ Designated as safety issue: Yes ]R. A response (R) was defined as a sustained (≥ 3 months) platelet count ≥ 30×10^9/L without recurrence of thrombocytopenia
- Evaluation of platelet response (No Response) [ Time Frame: The time frame is up to 3 months per subject ] [ Designated as safety issue: Yes ]NR.No response (NR) was defined as platelet count < 30 × 10^9/L or a less than two fold increase in platelet count from baseline or the presence of bleeding. Platelet count must be measured on two occasions more than a day apart.
- The number and frequency of therapy associated adverse events [ Time Frame: up to 3 months per subject ] [ Designated as safety issue: Yes ]

Drug: rhTPO in combination with Rituximab
Rituximab was given intravenously at a dose of 100 mg weekly for 4 consecutive weeks (Day 1, 8, 15, 22). Rh-TPO (TPIAOTM, a product of Sunshine Pharmaceutical Co Ltd, China, approved by China State Food and Drug Administration) was given subcutaneously at a dose of 1.0 μg/kg(300u/kg)for 14 days (Day 1-14).

Detailed Description:
Rituximab was given intravenously at a dose of 100 mg weekly for 4 consecutive weeks (Day 1, 8, 15, 22). Rh-TPO (TPIAOTM, a product of Sunshine Pharmaceutical Co Ltd, China, approved by China State Food and Drug Administration) was given subcutaneously at a dose of 1.0 μg/kg(300u/kg)for 14 days (Day 1-14). Platelet count (PC) was monitored every three or four days until day 22, followed by tests every week. Platelet transfusion was administered to patients with active bleeding symptoms or to those whose PC<10×10^9/L. Patients were followed for 3 months, and any adverse effects were recorded during the period of treatment and during the follow-up.

- Patients who are deemed unsuitable for the study by the investigator.
