Objective: To explore the moderating role of estradiol in the relationship between parenting styles and preschool children's behavioral problems, so as to provide a theoretical basis for improving the development of human s emotional health development in early life stage. Methods: During September to November in 2022, 354 children aged 3-6 years and their parents from two kindergartens in Bengbu City were chosen by using stratified cluster sampling method for the questionnaire survey. The Parenting Style Scale and the Child Behavior Checklist (CBCL) were used to collect information on parenting style and child behavioral problems. Salivary estradiol of children was collected and tested. Independent samples t test was applied to compare the scores of the scale for parental up bringing and children s behavioral problems, and Pearson correlation analysis was conducted to explore the relationship among parental upbringing, estradiol and children s behavioral problems. Results: Parents doting, laissez faire, autocratic, and inconsistent parenting styles were positive associated with child behavior problems( r =0.14-0.70); fathers democratic parenting style was negatively associated with child behavior problems( r =-0.14，-0.22，-0.21，-0.17，-0.27，-0.20); mothers democratic parenting styles was negatively correlated with scores on all five dimensions of child behavior problems except the withdrawal dimension ( r =-0.14，-0.12，-0.13，-0.21，-0.12)( P <0.05). Estradiol levels had significant moderating effects on maternal doting parenting style and children s withdrawal ( β =0.68) as well as social problems ( β =-1.00), also moderating laissez faire parenting styles and children s withdrawal problems ( β =0.75)( P <0.05). For children with low levels of estradiol, withdrawal problem scores were negatively associated with mother s doting parenting style and positively associated with laissez faire parenting style, and socialization problem scores were associated with mother s doting parenting style; for children with high levels of estradiol, withdrawal problem scores were positively associated with mother s doting parenting style, and socialization problem scores were associated with mother s doting parenting style ( t=2.84, 6.24, 3.16 , 2.37, 4.49, P <0.05). Conclusions Parenting styles are strongly associated with child behavioral problems; estradiol levels play a moderating role in mothers doting, laissez faire parenting styles and children s withdrawal problems and social problems.Parents should adopt more positive parenting styles and focus on the role of estradiol levels in maternal education to reduce the occurrence of behavioral problems in children.

The molecularly imprinted polymers membranes(MIPMs)were prepared for selective adsorption of lamotrigine(LTG)in plasma by surface molecular imprinting technology with polyvinylidenefluoride(PVDF)membranes as supporter,lamotrigine as template molecule,methyl methacrylate as functional monomer,ethylene glycol dimethacrylate as cross-linking agent,azodiisobutyronitrile as initiator and acetonitrile-dimethylformamide(1∶1.5,V/V)as pore-forming agent.The prepared MIPMs were characterized by scanning electron microscope,Fourier transform infrared spectroscopy,Brunaner-emmet-teller measurements,X-ray photoelectron spectroscopy,and thermogravimetric analysis.The adsorption properties of the materials were investigated by kinetic adsorption,isothermal adsorption,selective adsorption,adsorption-desorption and reusability experiments.The results showed that the imprinted layer of LTG was successfully coated on the surface of PVDF,and the materials had uniform particle size.The adsorption capacity and imprinting factor of the MIPMs towards LTG were 3.77 mg/g and 8.97,respectively.The nanomaterials showed fast mass transfer rate(30 min)and good reusability(the adsorption efficiency was 86.66%after 6 cycles),and could be used for the adsorption of LTG in plasma with low matrix interference,recoveries of 86.54%-90.48%and RSD of 1.51%-3.15%(n=5).The proposed LTG MIPMs were demonstrated to be simple and environment friendly,and had high selectivity in rapid separation and extraction of LTG in plasma.

Objective To investigate the effect and mechanism of rhubarb Tangluo pill on liver injury in type 2 diabetic rats.Methods ZDF(fa/fa)rats were given high-fat diet to induce type 2 diabetes model,and were randomly divided into model group,positive control group(0.18 g·kg-1 metformin)and experimental-L,-M,-H groups(0.54,1.08 and 2.16 g·kg-1 rhubarb Tangluo pill),with 8 rats in each group.Eight ZDF(fa/+)rats were selected as control group.The control group and model group were given equal volume of pure water once a day for 12 weeks.An oral glucose tolerance test(OGTT)was performed after administration.Fasting blood glucose level,body mass and liver mass of rats were measured and liver index was calculated.The contents of glutamic-pyruvic transaminase(GPT),glutamic oxalacetic transaminase(GOT),triglyceride(TG)and total cholesterol(TC)in serum were detected.The histomorphologic changes of liver were observed by hematoxylin-eosin(HE)staining and Masson staining.The protein expression of phosphorylated insulin receptor substrate 1(p-IRS1),phosphorylated protein kinase B(p-Akt)and glucose transporter 4(GLUT4)were detected by Western blotting.Results After administration,the fasting blood glucose levels of control group,model group,positive control group and experimental-H group were(4.71±0.45),(29.9±2.97),(15.28±4.52)and(13.84±1.55)mmol·L-1,respectively;the liver index were 2.31±0.46,4.03±0.18,3.37±0.23 and 3.38±0.24;the relative expression level of p-IRS1 protein were 1.00±0.36,4.00±0.11,1.62±0.27 and 1.90±0.17,respectively;the relative expression levels of p-Akt protein were 1.00±0.25,0.21±0.04,0.73±0.15 and 0.54±0.04,respectively;GLUT4 protein relative expression levels were 1.00±0.11,0.40±0.08,0.86±0.04 and 0.70±0.06,respectively.Compared with the model group,the above indexes in the experimental-H group were statistically significant(P＜0.01,P＜0.05).Conclusion Rhubarb Tanglu pill can effectively improve glycolipid metabolism and liver injury in type 2 diabetes mellitus,and its mechanism may be related to the activation of IRS1/Akt signaling pathway.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Misuse of pyrrolizidine alkaloid (PA)-containing herbs is the major cause of hepatic sinusoidal obstruction syndrome (HSOS) in China. And diuretics are among the most commonly used medications for the treatment of PA-induced HSOS in clinical practice. As a traditional diuretic in traditional Chinese medicine, the diuretic mechanism of Alismatis Rhizoma (AR) has not been fully clarified, and there is no report on AR ameliorating PA-induced HSOS from a diuretic point of view. Therefore, this study aims to investigate the therapeutic potential of alisol B 23-acetate (AB23A) against acute liver injury induced by senecionine (a representative toxic PA) in mice, and to further elucidate its effect on impaired water-liquid balance in mice exposed to PA. All experiments were approved by the Animal Research Committee of Shanghai University of Traditional Chinese Medicine (Registration number: PZSHUTCM220808017). Animal welfare and the animal experimental protocols were strictly consistent with related ethics regulations of Shanghai University of Traditional Chinese Medicine. Model of mice was induced by a single oral exposure of senecioine (50 mg·kg^-1) (SEN group), and AB23A (40 mg·kg^-1) intervention group (AB23A+SEN group), solvent control group (Ctrl group) and AB23A control group (AB23A group) were set up. The results showed that AB23A could significantly attenuate the levels of serum biochemical indices of liver functions in senecioine-induced acute liver injury mice, as evident by alleviated hepatocyte necrosis and hepatic sinusoidal stasis. AB23A also improved kidney function of mice exposed to senecionine, fascinated urinary excretion and repaired electrolyte disorders, as well as decreased content of senecioine metabolites. Further, the protein and mRNA expression of genes related to the water balance pathway were measured. AB23A could significantly down-regulate the elevated protein and mRNA expression levels of aquaporin 2 (AQP2) and angiotensin II type 1 receptor, and inhibit the transport of AQP2 to the apical plasma membrane induced by senecionine exposure. AB23A also significantly decreased serum levels of angiotensin II. In vitro studies further confirmed that AB23A regulates AQP2 expression in renal inner medullary collecting duct cells 3 (IMCD3). These data indicate that AB23A regulates the expression of AQP2 in renal medulla, thereby affecting its water reabsorption in mice with senecionine-induced acute liver injury. This work achieves a better understanding of the diuretic effect of AR, and provides experimental foundation and theoretical basis for the treatment of PA-induced acute liver injury by AR in clinics.

Objective To investigate the mechanism of Bushen Yixin Tablets in the treatment of diabetic nephropathy(DN).Methods The key targets of Bushen Yixin Tablets for the treatment of DN were predicted by network pharmacology.A high-glucose-processed MPC-5 cell model was constructed,enzyme-linked immunosorbent assay(ELISA),real-time quantitative polymerase chain reaction(RT-qPCR)and Western Blot were applied to verify the potential action targets and pathways of Bushen Yixin Tablets for the treatment of DN.Results Twenty-four active ingredients were obtained from Bushen Yixin Tablets.There were 131 targets involved in the treatment of DN by Bushen Yixin Tablets,and the results of pathway enrichment analysis showed that the key targets might mainly focus on inflammatory pathways,lipids and atherosclerosis.The further experimental validation showed that,compared with the high glucose group,the secretion level of matrix metalloproteinase 1(MMP-1)in the supernatant of MPC-5 cells in the medium-and high-dose groups of Bushen Yixin Tablets medicated serum were increased(P＜0.001),and the secretion levels of tissue inhibitor of metalloproteinase 1(TIMP-1)and transforming growth factor β1(TGF-β1)were decreased(P＜0.001).Compared with the high glucose group,the protein and mRNA expression levels of MMP1 and BCL-2 in the high-dose group of Bushen Yixin Tablets medicated serum were increased(P＜0.001),and the protein and mRNA expression levels of phosphatidylinositol 3-kinase(PI3K)and protein kinase B(AKT)were decreased(P＜0.001).Conclusion Bushen Yixin Tablets may play a protective role against DN by inhibiting the proliferation of glomerular mesangial cells and promoting the degradation of extracellular matrix through PI3K/AKT/BCL-2 pathway.

The UK screening and treatment of retinopathy of prematurity(ROP)updated 2022 guidelines were developed by a multidisciplinary guideline development group from the Royal College of Paediatrics and Child Health and the Royal College of Ophthalmologists,following the standards of the National Institute for Health and Care Excellence.They were published on the websites of the Royal College of Paediatrics and Child Health and the Royal College of Ophthalmologists in March 2022,and formally published in Early Human Development in March 2023.The guidelines provide evidence-based recommendations for the screening and treatment of ROP.The most significant change in the 2022 updated version compared to the previous guidelines is the lowering of the gestational age screening criterion to below 31 weeks.The treatment section covers treatment indications,timing,methods,and follow-up visits of ROP.This article interprets the guidelines and compares them with ROP guidelines/consensus in China,providing a reference for domestic peers.
