Brief summary: In order to further improve the therapeutic efficacy of advanced no-squamous non-small cell lung cancer patients, improve the life cycle, this study will take the standard after treatment pemetrexed combined other anti-angiogenesis drugs to maintain as the direction, so as to provide more over the evidence for the treatment of advanced NSCLC.

Detailed description: In patients with advanced non-squamous non-small cell lung cancer, patients receiving pemetrexed and platinum-based chemotherapy after 4 cycles of non-progressive evaluation were treated with pemetrexed plus apatinib. Until the disease progresses, there are intolerable side effects or the patient requests to withdraw from the study. It is planned to include 20 subjects.

Dosing regimen： Apatinib 500mg po qd (If there is a 3-4 degree toxic side reaction after 14 days of administration, the dose can be lowered to 250mg qd); Pemetrexed 500 mg/m2 d1×q3w; Until the patient progresses, the toxicity is intolerable, the patient withdraws his knowledge, or the investigator judges that the medication must be discontinued.

Eligibility criteria: Inclusion Criteria:

1. Stage IV non-squamous non-small cell lung cancer diagnosed by pathology.
2. At least one measurable lesion.
3. If the genetic test (EGFR/ALK) is an EGFR-sensitive mutation or an ALK fusion gene-positive patient, it is necessary to receive targeted therapy for the first-line treatment; if there is no mutation, it is necessary to be a first-line patient.
4. Pemetrexed combined platinum induction chemotherapy after 4 cycles of RECIST curative effect evaluation of patients who were not progress.
5. Gender is not limited, age: ≥ 18 years old.
6. ECOG PS: 0-2 points.
7. Estimated lifetime ≥3 months
8. Organ function levels meet the following criteria:

   * Blood routine examination standards must meet: ANC≥1.5×109/L, PLT≥100×109/L, Hb≥100g/L (No blood transfusion and blood products within 14 days, not corrected by G-CSF and other hematopoietic stimulating factors).
   * Biochemical examination must be in accordance with the following criteria: TBIL\<1.5×ULN, ALT, AST and ALP\<2.5×ULN, BUN and Cr≤1×ULN or Endogenous creatinine clearance≥50ml/min (Cockcroft-Gault formula).
9. Women of childbearing age must have reliable contraceptive measures, or in the group of 7 days before the pregnancy test (serum or urine), and the results were negative, and willing to during the test and the last for 8 weeks after experimental drug using appropriate methods of contraception.For men, must be agreed to at the end of the experiments and tests of giving drugs after 8 weeks using appropriate methods of contraception or has sterilization surgery.
10. Subjects were willing to join in this study, signed informed consent, good adherence, cooperate with the follow-up.

Exclusion Criteria:

2. Patient gene detection is EGFR sensitive mutation, or positive for ALK fusion gene.
3. Symptomatic brain metastasis (a patient with brain metastases who completed treatment and had stable symptoms 21 days before enrollment can be enrolled, but need to be confirmed by brain MRI, CT or venography to have no cerebral hemorrhage symptoms).
4. Imaging (CT or MRI) showed tumor lesions ranging from ≤ 5 mm to large vessels, or central tumors that invaded local large blood vessels; or showed significant pulmonary cavitary or necrotizing tumors.
5. Hypertension (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg) that is still uncontrollable using a combination of two antihypertensive drugs.
6.

7. Patients with a history of pulmonary interstitial disease or a patient with pulmonary interstitial disease.
8. Abnormal coagulation (INR \> 1.5 or prothrombin time (PT) \> ULN + 4 seconds or APTT \> 1.5 ULN), with bleeding tendency or undergoing thrombolysis or anticoagulant therapy.
9. There is obvious cough blood in the 2 months before enrollment, or the daily hemoptysis amount is 2.5ml or more.
