Aim To investigate the antitumor and antiangiogenic effects of combined low-dose cyclophosphamide(CTX)and recombined VEGF protein vaccine.Methods In this experiment,H22 hepatocellular carcinoma model was established in BALB/c mice.Mice were randomly divided into four groups: control group,CTX group(CTX),VEGF protein vaccine group(V2)and CTX plus V2 group(CTX+V2).The anti-tumor efficacy and antiangiogenic effect were investigated using a subcutaneous tumor model and an intradermal tumor model.Western blot and ELISAwere further adopted to detect the specific anti-VEGF antibody.Results CTX+V2 group displayed a lower tumor volume and tumor weight than either the single therapy group in the subcutaneous tumor model(P<005 vs V2,P<001 vs CTX).Meanwhile,CTX+V2 was more effective for antagonizing tumor-associated angiogenesis compared with either the single therapy(P<005 vs V2,P<001 vs CTX).After CTX+V2 immunization,high titer of anti-VEGF antibody was detected by ELISA and verified by Western blot.Conclusion The therapy of CTX combined with V2 has significant synergistic effect against H22 hepatocellular carcinoma.

Objective To explore the value of controlled decompression under intracranial pressure monitoring in craniotomy of patients with severe cerebral hemorrhage.Methods One hundred and six patients with severe cerebral hemorrhage,admitted to our hospital from January 2015 to July 2018,were prospectively enrolled.These patients were divided into control group (n=5 l) and treatment group (n=55) according to their families' wishes.The patients in the control group were treated with traditional craniotomy and hematoma removal;the patients in the treatment group were treated with controlled decompression combined with craniotomy and hematoma clearance under intracranial pressure monitoring,and intracranial pressure monitoring and management were carried out after operation.The rate of bone flap acceptance during operation,incidences of complications such as re-bleeding,scalp exudation,intracranial infection and cerebral infarction after operation,rate of re-operation and Glasgow outcome scale scores 6 months after injury were compared and analyzed between the two groups.Results Five patients had midway withdrawal (2 from the control group and 3 from the treatment group),and 101 patients (49 from the control group and 52 from the treatment group) were included in the statistical analysis.The rate of bone flap acceptance in the treatment group (69.2%) was significantly higher than that in the control group (24.5%,P<0.05).The incidences of complications such as bleeding,scalp exudation,intracranial infection and cerebral infarction (11.5%,7.7%,3.8%,and 13.5%) were significantly lower than those in the control group (30.6%,22.4%,16.3%,and 34.7%,P<0.05).The re-operation rate (3.8%) was significantly lower than that in the control group (16.3%,P<0.05).Good recovery rate in the treatment group (76.9%) was significantly higher than that in the control group (55.1%,P<0.05).The mortality rate (7.7%) was significantly lower than that of the control group (22.4%,P<0.05).Conclusion For patients with severe cerebral hemorrhage,controlled decompression under intracranial pressure monitoring combined with craniotomy and hematoma removal can significantly improve the rate of bone flap acceptance,reduce the rate of second-stage cranioplasty,reduce the incidence of complications and re-operation rate,and more effectively improve the quality of life and prognosis of patients.
