The chemical components of Carthami Flos were investigated by using macroporous resin, silica gel column chromatography, reversed-phase octadecylsilane(ODS) column chromatography, Sephadex LH-20, and semi-preparative high-performance liquid chromatography(HPLC). The planar structures of the compounds were established based on their physicochemical properties and ultraviolet-visible(UV-Vis), infrared(IR), high-resolution electrospray ionization mass spectrometry(HR-ESI-MS), and nuclear magnetic resonance(NMR) spectroscopic technology. The absolute configurations were determined by comparing the calculated and experimental electronic circular dichroism(ECD). Six flavonoid C-glycosides were isolated from the 30% ethanol elution fraction of macroporous resin obtained from the 95% ethanol extract of Carthami Flos, and identified as saffloquinoside F(1), 5-hydroxysaffloneoside(2), iso-5-hydroxysaffloneoside(3), isosafflomin C(4), safflomin C(5), and vicenin 2(6). Among these, the compounds 1 to 3 were new chalcone C-glycosides. The compounds 1, 2, 4, and 5 could significantly increase the viability of H9c2 cardiomyocytes damaged by oxygen-glucose deprivation/reoxygenation(OGD/R) at a concentration of 50 μmol·L~(-1), showing their good cardioprotective activity.

OBJECTIVES:
To investigate the incidence of small for gestational age (SGA) infants among singleton live births and identify risk factors.
METHODS:
Clinical data for 1 020 singleton live-born infants and their mothers at People's Hospital Affiliated to Shandong First Medical University from January 2019 to January 2024 were retrospectively collected. The incidence of SGA was calculated, and univariate and multivariable logistic regression analyses were performed to determine independent risk factors.
RESULTS:
Among 1 020 singleton live births, the incidence of SGA was 9.90%. SGA was more frequent in female neonates and in cases with lower placental weight or umbilical cord abnormalities (all P<0.05). Both preterm and post-term birth showed significant linear trends with SGA incidence (P<0.05). Maternal factors associated with higher SGA incidence included age <20 years or ≥35 years, primary-school education or below, low pre-pregnancy body mass index (BMI), insufficient gestational weight gain, gestational hypertension, diabetes, anemia, hyperthyroidism, hypothyroidism, amniotic fluid/placental abnormalities, and smoking history (all P<0.05). Multivariable logistic regression identified preterm birth, post-term birth, low placental weight, umbilical cord abnormalities, low pre-pregnancy BMI, insufficient gestational weight gain, gestational hypertension, anemia during pregnancy, and maternal smoking as independent risk factors for SGA (all P<0.05).
CONCLUSIONS
The occurrence of SGA among singleton live births is associated with preterm or post-term delivery, low placental weight, umbilical cord abnormalities, low pre-pregnancy BMI, inadequate gestational weight gain, gestational hypertension, anemia during pregnancy, and maternal smoking. Targeted strengthening of perinatal management is warranted to reduce the risk of SGA.

OBJECTIVE:
Huachansu injection (HCSI), a promising anti-cancer Chinese medicine injection, has been reported to have the potential for reducing the toxicity of chemotherapy and improving the quality of life for colorectal cancer (CRC) patients. The objective of this study is to explore the synergistic and detoxifying effects of HCSI when used in combination with irinotecan (CPT-11).
METHODS:
To investigate the effect of HCSI on anti-CRC efficacy and intestinal toxicity of CPT-11, we measured changes in the biological behavior of LoVo cells in vitro, and anti-tumor effects in LoVo cell xenograft nude mice models in vivo. Meanwhile, the effect of HCSI on intestinal toxicity and the uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) expression was investigated in the CPT-11-induced colitis mouse model. Subsequently, we measured the effect of HCSI and its 13 constituent bufadienolides on the expression of UGT1A1 and organic anion transporting polypeptides 1B3 (OATP1B3) in HepG2 cells.
RESULTS:
The combination index (CI) results showed that the combination of HCSI and CPT-11 exhibited a synergistic effect (CI < 1), which significantly suppressing the LoVo cell migration, enhancing G2/M and S phase arrest, and inhibiting tumor growth in vivo. Additionally, the damage to intestinal tissues was attenuated by HCSI in CPT-11-induced colitis model, while the increased expression of UGT1A1 in HepG2 cells and in mouse was observed.
CONCLUSION
The co-therapy with HCSI alleviated the intestinal toxicity induced by CPT-11 and exerted an enhanced anti-CRC effect. The detoxifying mechanism may be related to the increased expression of UGT1A1 and OATP1B3 by HCSI and its bufadienolides components. The findings of this study may serve as a theoretical insights and strategies to improve CRC patient outcomes.
