ObjectiveTo investigate the effect of video-based educational intervention combined with maternal presence on perioperative adverse outcomes in preschool children undergoing general anesthesia， including cooperation in anesthesia induction， perioperative anxiety， pain and agitation during recovery. MethodsA total of 300 preschool children scheduled for general anesthesia in our hospital from June to December 2023 were randomly assigned to control group （n=150） and intervention group （n=150）. The control group received routine recovery care. For the intervention group， in addition to routine recovery care， a preoperative visit was scheduled one day before surgery. During this visit， mothers were guided to watch anesthesia videos with their children. During the waiting period in the operating room and 30 minutes after awakening， the mothers were guided to accompany the children for more than 30 minutes. Recovery conditions were recorded using the surgical anesthesia information system， and the children’s anesthetic induction compliance， perioperative anxiety， pain， and agitation were evaluated and recorded using the modified Yale Preoperative Anxiety Scale （m-YPAS）， the Induction Compliance Scale （ICC）， the Children’s Pain Behavior Scale （FLACC）， and the Pediatric Agitation and Emergence Delirium Scale （PAED）. ResultsOn the preoperative visit day， there were no statistically significant differences in baseline data between the two groups （P > 0.05）. For perioperative anxiety， the m-YPAS scores of the intervention group were significantly lower than those of the control group， both when entering the operating room waiting area （35.27±6.48 vs. 41.79±6.68， P < 0.05） and 30 minutes after postoperative recovery （20.13±7.05 vs. 35.75±9.51， P < 0.05）. In terms of anesthesia induction cooperation， the ICC scores of the intervention group were significantly lower than those of the control group （1.84±0.95 vs. 3.17±0.62， P < 0.05）， and the proportion of good induction cooperation was significantly higher than that of the control group （24.00% vs. 12.67%， P < 0.05）. There was no significant difference in awakening duration between the two groups， but the intervention group had a significantly shorter length of stay in the post-anesthesia care unit than the control group （0.90±0.29 hours vs. 1.29±0.42 hours， P < 0.001）. For perioperative agitation， the PAED scores of the intervention group were significantly lower than those of the control group （entering in the operating room waiting area： 8.5 vs. 9.2， P < 0.05； 30 minutes after postoperative recovery： 4.2 vs. 7.8， P < 0.05）. In terms of pain scores， the FLACC scores of the intervention group were also significantly lower than those of the control group， both when entering the operating room waiting area （ 5.3 vs. 6.7， P < 0.05； 30 minutes after postoperative recovery： 2.1 vs. 4.9， P < 0.05）. ConclusionsVideo-based educational intervention combined with maternal presence reduces the perioperative anxiety， pain and agitation of preschool children undergoing general anesthesia， and improved the compliance of anesthesia induction. It is recommended to promote this intervention measure in clinical practice.

OBJECTIVE To investigate the effect of salidroside (Sal) on bone loss in obstructive sleep apnea syndrome(OSAS) rats by regulating the osteoprotegerin(OPG)/receptor activator of nuclear factor kappa-B ligand(RANKL) pathway. METHODS Rats were randomly divided into(12 rats/group) control group,OSAS group,Sal-L,Sal-M,and Sal-H groups(17.5,35,70 mg/kg). Except for the control group,all other groups were used to replicate the OSAS rat model through hypoxia and reoxygenation cycles. Bone density meters,three-point bending experiments,and Micro CT were applied to measure the bone density,biomechanics,and microstructural changes of the femur in rats. ELISA method was applied to detect serum levels of osteocalcin(BGP),alkaline phosphatase(ALP),and cross-linked carboxy-terminal telopeptide of type Ⅰ collagen(CTX-I). RT-PCR was applied to detect OPG and RANKL mRNA levels in the femur. Western blotting was applied to detect the expression of OPG/RANKL pathway proteins in the femur. RESULTS Compared with the control group,the bone density,maximum intensity,maximum load,trabecular bone volume fraction(Tb.BV/TV),trabecular number(Tb.N),trabecular thickness(Tb.Th),BGP,ALP,OPG mRNA and protein expression,OPG/RANKL ratio of rats in the OSAS group were decreased,the mRNA and protein expression of CTX-I and RANKL were increased(P<0.05). Compared with the OSAS group,the bone density,maximum intensity,maximum load,Tb.BV/TV,Tb.N,Tb.Th,BGP,ALP,OPG mRNA and protein expression,OPG/RANKL ratio of rats in the Sal-L,Sal-M,and Sal-H groups were increased sequentially,the mRNA and protein expression of CTX-I and RANKL were decreased sequentially,the above changes were most great in the Sal-H group(P<0.05). CONCLUSION Salidroside promotes bone formation and inhibits bone resorption by increasing OPG expression and decreasing RANKL expression,thereby reducing bone loss in OSAS rats.

At the same time, this paper summarizes the influencing factors of father's support for breastfeeding from four aspects, including father's sociodemographic characteristics, breastfeeding knowledge, attitude towards breastfeeding, and psychological state, providing reference for formulating interventions to improve father's support for breastfeeding and further promote breastfeeding.

ObjectiveTo analyze changes of the chemical composition in Euodiae Fructus before and after processing with Coptidis Rhizoma decoction， so as to provide scientific basis for elucidating the processing mechanism of this decoction pieces. MethodUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF/MS） was performed on a Titank C₁₈ column （2.1 mm×100 mm， 1.8 μm）， the mobile phase was 0.1% formic acid aqueous solution-acetonitrile for gradient elution， the column temperature was set at 40 ℃， the flow rate was 0.25 mL·min^-1. Electrospray ionization （ESI） was used to scan in positive and negative ion modes， and the scanning range was m/z 50-1 250. The chemical constituents in Euodiae Fructus were identified before and after processing by reference substance comparison， database matching and literature reference， and MarkerView™ 1.2.1 software was used to normalize the obtained data， SIMCA-P 14.1 software was employed to perform principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） on MS data of raw and processed products to screen the differential components before and after processing. ResultA total of 50 compounds were identified， including 48 kinds of stir-fried products with Coptidis Rhizoma decoction and 44 kinds of raw products. After processing， six compounds were added， including danshensu， noroxyhydrastinine， oxyberberine， 13-methylberberrubine， protopine and canadine. However， two kinds of compounds， including （S）-7-hydroxysecorutaecarpine and wuchuyuamide Ⅱ， were not detected after processing. In general， after processing， the overall contents of phenolic acids and flavonoids decreased significantly， the overall content of limonoids increased， and the overall content of alkaloids did not decrease insignificantly. The results of PCA and OPLS-DA showed that there were significant differences in the composition and content of the chemical components of Euodiae Fructus before and after processing， and a total of 12 variables such as quercetin， dihydrorutaecarpine and dehydroevodiamine were obtained by screening. ConclusionEuodiae Fructus stir-fried with Coptidis Rhizoma decoction mainly contains phenolic acids， flavonoids， limonoids and alkaloids. The composition and content of the chemical components have some changes before and after processing. The addition of processing excipients and hot water immersion are the main reasons for the difference， which can provide experimental basis for interpretation of the processing mechanism of this characteristic processed products of Euodiae Fructus.
