Positive and Negative Syndrome Scale （PANSS）	Change from Baseline in Positive and Negative Syndrome Scale in part Ⅱ。 The PANSS measures symptom severity of participants with schizophrenia and contains 7 positive symptom scales,7negative system scales, and 16 general psychopathology symptom scales. Participants are rated from 1 to 7 on each symptom scale with a total minimum score of 30 and a maximum score of 210. A decrease in PANSS total score correlates with an improvement in schizophrenia symptoms.	Day-1,Day14,Day28 and Day42
PANSS Positive subscale score	Change from Baseline in PANSS Positive subscale score in part Ⅱ PANSS-Positive: Assessment of positive symptoms. Minimum value:7, maximum value:49, the higher scores mean a worse outcome.	Day-1, Day14, Day28 and Day42
PANSS Negative subscale score	Change from Baseline in PANSS Negative subscale score in part Ⅱ。 PANSS-negative: Assessment of negative symptoms. Minimum value:7, maximum value:49, the higher scores mean a worse outcome.	Day-1, Day14, Day28 and Day42

Clinical Global Impression-Severity (CGI-S)	Change from Baseline in Clinical Global Impression-Severity in part Ⅱ。 The CGI-S rating scale is a 7-point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants". Negative change from baseline scores indicate improvement in the severity of illness.	Day-14, Day28 and Day42
Rac	Accumulation Ratio of VV119	Baseline to 360 hours after the last administration
