This is an open-label, single-arm, phase II, multi-center clinical trial. Subjects can only enter this study after they meet the inclusion and exclusion criteria. All enrolled patients will receive the treatment with anti-PD-1 combined with albumin-bound paclitaxel, every 3 weeks, until progressive disease, initiation of new anti-tumour therapy, death, intolerable toxicity. Albumin-bound paclitaxel may be used for up to 6 cycles and anti-PD-1 for up to 2 years.

Inclusion Criteria:
