Methods:Mice were treated with different proportions of the P and C drug pair (1:1, 3:1, and 4:1) for 10 days, and subsequentlyinjected with atropine (ATR) or neostigmine (NEO). The effects of the different proportions of P and C were evaluatedbased on the alvine advance rate. In addition, we used the same modeling method used in the first experiment andadministered P: C at ratio of 3:1 and at different doses respectively (4.68 g/L, 2.34 g/L, and 1.17 g/L), and tested levelsof the gastrointestinal hormones, gastrin (GAS), vasoactive intestinal polypeptide (VIP), and somatostatin (SS) in thesmall intestinal tissue using an enzyme-linked immunosorbent assay. Results: In the groups of NEO-induced mice, P:Cat ratios of 1:1, 3:1, and 4:1 significantly reduced the alvine advance rate compared with the NEO model group (P =0.003, P = 0.012 and P = 0.021, respectively). In the groups of ATR-induced mice, only P:1 at ratio of 3:1 significantlyincreased the alvine advance rate compared with the ATR model group (P = 0.007). After exposure to P: C at ratio of 3:1and at different dose, the GAS level was lower in the low-, medium-, and high-dose NEO groups than that in the NEOmodel group (P = 0.001, P = 0.004, and P = 0.003, respectively). The VIP levels were higher in the medium-andhigh-dose NEO groups than that in the NEO model group (P = 0.004 and P = 0.002, respectively). In addition, the SSlevel increased in the NEO medium-dose group compared with that in the NEO model group (P = 0.002). The GAS levelwas higher in the ATR medium- and high-dose groups than in the ATR model group (P = 0.007 and P = 0.021,respectively). The VIP level was lower in the ATR low-, medium-, and high-dose than that in the ATR model group (P =0.001, P = 0.001, and P = 0.001, respectively). Furthermore, the SS level was lower in the ATR medium- and high-dosegroups than that in the ATR model group (P = 0.001 and P = 0.006). Conclusion: The PC drug pair bidirectionallyadjusted the NEO- and ATR-induced functional dyspepsia in mice by modulating GAS, VIP, and SS levels in theintestine.展开更多

Long-term toxicity testing in domestic rabbits showed that after SFI was administered for 90 days, the animals in each dosing group showed no chronic toxic reactions. Among 20 100 cases observed, the incidence of an ADR was 1.85‰. From March to November 2013,of the leading institutions and 22 sub-centers involved in the post-marketing clinical safety intensive hospital monitoring, 21 units completed 8484 cases of monitoring, and reported 23 cases of adverse reactions. No damage to renal function was found using SFI ata dosageanda treatment course larger and longer than that recommended for the adjuvant treatment of tumors. This could reduce the mortality rate of admitted patients based on the analysis of the data provided by the HIS. A total of 16 clinical case reports of adverse reactions related to SFI in 1999-2012 were obtained through literature retrieval. These reports contained information concerning 17 cases, with adverse reaction symptoms including thrombocytopenia, rash,chills,feeling cold,palpitation,dyspnea,edemaofa lower extremity, palpebral edema, and superficial vein in flammation,among others.CONCLUSION: This study introduces "get full access" to the flow of information on medicines regarding their ADR incidence rate and characteristics and factors.It supports the safety of SFI for clinical, research, and production uses based on objec-tive, reliable, and scientific information to provide safe medication.展开更多
