About this trial
This is an interventional treatment trial for Malignant Pleural Effusion
Eligibility Criteria
Inclusion Criteria:

- Pathological confirmed advanced malignant tumor with malignant pleural or peritoneal effusion;
- Vital signs stable, Eastern Cooperative Oncology Group (ECOG) Performance Status 0-2;
- Age ≥ 18 years old, gender unlimited;

- Subjects agree to take effective contraceptive measures at the time of enrollment and within 4 months after enrollment. The pregnancy test of female patients must be negative;
Sufficient bone marrow, liver and kidney functions. Laboratory tests within 7 days before the first drug use meet the following requirements:
- Coagulation function: APTT ≤ 1.5 × ULN, while INR or PT ≤ 1.5 × ULN (not receiving anticoagulant therapy); ② Blood routine examination: Hgb ≥ 80g / L, WBC > 3 × 10^9/L、NEU≥1.0 × 10^9/L、PLT≥80 × 10^9/L;
- Liver function: total bilirubin ≤ 1.5 times the upper limit of normal value (ULN); AST and alt ≤ 2.5 times ULN (if abnormal liver function is mainly caused by tumor infiltration, it can be ≤ 5 times ULN; alkaline phosphatase ≤ 2.5 times ULN; ④ Renal function: bun and Cr ≤ 1.5 times ULN, creatinine clearance ≥ 40ml / min (calculated by Cockcroft Gault formula).
Exclusion Criteria:

- Subjects with active hemolytic anemia;
- Subjects with active central nervous system metastases were excluded, except those with brain metastases or asymptomatic cancer cells found in cerebrospinal fluid;
- Pregnant or lactating female;
- Systemic active infection, serious coagulation disorder or serious heart, respiratory and immune system diseases;
- Congenital or acquired immune function defects (such as HIV infection), hepatitis B infection (HBV-DNA ≥ 10 ^ 4 / ml), hepatitis C infection (HCV antibody and HCV RNA positive);
- Subjects who had serious infection within 4 weeks before the first medication were excluded, including but not limited to infectious complications, bacteremia and severe pneumonia requiring hospitalization;
Subjects with active autoimmune diseases or a history of autoimmune diseases that may recur, but the following are not excluded:
- Type 1 diabetes
- Hypothyroidism (if controlled by hormone replacement therapy only)
- Controlled celiac disease ④ Skin diseases without systemic treatment (such as vitiligo, psoriasis, alopecia) ⑤ Any other disease that does not recur without external triggers.
- Those who had severe hypersensitivity to the drugs used in this protocol in the past;
- Subjects who are ready for or have previously received tissue / organ transplantation;
- Subjects with large pericardial effusion were excluded;
- Exclude those who have suffered from other malignant tumors within 2 years, except for cervical carcinoma in situ, low-risk gastrointestinal stromal tumor, skin basal cell carcinoma, skin squamous cell carcinoma, thyroid papillary carcinoma and breast ductal carcinoma in situ that have been effectively removed;
- Exclude subjects who have been vaccinated or will be vaccinated with live vaccine within 4 weeks before the first administration;
- Other circumstances that the investigator considers inappropriate for clinical trials.

Placebo Comparator
Virus Activated Killer immune Cells(VAK)
saline
The VAK should be given once a week, three times a circle. The VAK could given 1 or 2 circle for each subject. The dosage of Pleural Effusion(more than 10^5/kg cells in 30-50mL solvent) differs from Peritoneal Effusion(more than 10^4/kg cells in 30-50mL solvent)
50ml of saline was injected once a week,three times a circle.The saline could given 1 or 2 circle for each subject.
