In the past 11 years ,the human genome research has made a great progress.This will bring about another revolution in the life sciences development and challenges of a series of social ethical principles.So it is necessary to abide by the basic point of social ethical principles and build up developmental system between human genome science and social ethical principles.It is favourable to coordinate their relations and bring about the healthful development of human genome science and bring benefits to mankind.

This paper was aimed to establish screening methods of anaphylactoid reaction caused by safflower yellow for injection based on RBL-2 H3 cell degranulation model and mice model for acute anaphylactoid reaction,and evaluate the hypersensitivity caused by safflower yellow for injection from different batches. An in vitro cell model was used to keep the cells stimulated for an hour with different batches of safflower yellow for injection as the drug group,serum-free MEM medium as negative control group and 30 mg·L-1 C48/80 as positive control group respectively. The supernatant was then absorbed,and neutral red staining technique was used to detect the effect of safflower yellow injection on the degranulation of RBL-2 H3 cells with the positive cell rate of degranulation as the indicator.An in vivo model was established to validate the experimental results,and mice model for acute anaphylactoid reaction and ELISA method were adopted to detect the plasma histamine content,and screen the hypersensitivity caused by safflower yellow for injection at the animal level by using plasma histamine content as a test index. The results of the neutral red staining experiments showed that the positive control C48/80 could cause cell degranulation,and most of the cells were deeply stained. There was significant difference in positive cell rate between different batches of safflower yellow and positive control group. In the mice model for acute anaphylactoid reaction,it was found that the positive control C48/80 significantly increased the histamine content in the plasma of mice,while the safflower yellow in each batch did not cause a significant increase in plasma histamine( P<0. 000 1). The mechanism of anaphylactoid reaction is relatively complicated. This study was mainly based on the release of histamine and other active substances by degranulation of mast cells. No significant degranulation reaction of RBL-2 H3 cells induced by safflower yellow for injection was detected,nor was the plasma histamine level significantly increased in mice from the in vitro and in vivo aspects.

OBJECTIVE To investigate and analyze the operational costs and current charging policies of pharmacy intravenous admixture service （PIVAS） in China， and provide a reference for promoting high-quality and sustainable development of PIVAS. METHODS Questionnaires were distributed in 30 provinces， autonomous regions， and municipalities across the country through the “Wenjuanxing” platform from May 6th to July 1st， 2022. The operational costs， charging status and suggestions of PIVAS were investigated and analyzed. RESULTS A total of 761 PIVAS participated in the survey nationwide， including 666 tertiary medical institutions， 93 secondary medical institutions， and 2 primary medical institutions. Approximately 60.58% of PIVAS had implemented a charging system that allowed charges. Among them， most PIVAS required inspection and evaluation before charging. The annual operating cost of PIVAS in China was approximately 2 098 100 yuan， with the integrated operating cost comprising 89.36% of the total， while the dispensing cost accounted for only 10.64%. Human costs emerged as the highest annual consumption （74.20%）， followed by decoration and facility maintenance costs （4.77%） and equipment acquisition costs （3.44%）. Regarding charges for different drugs nationwide， common drugs had an average charge standard of 4.39 yuan per bag while antibacterial drugs averaged 5.01 yuan per bag； hazardous drugs had an average charge of 23.17 yuan per bag， whereas parenteral nutrition solutions averaged 38.75 yuan per bag. However， the recommended average charges of the four drugs mentioned above were 6.71， 9.63， 38.35 and 44.03 yuan per bag， respectively. CONCLUSIONS At present， there is no unified inspection and evaluation standard and charging standard in China. Moreover， the current charging standard is lower than the recommended standard. It is necessary to combine operational costs and develop more reasonable and fair charging standards.
