Taxifolin (Tax) has been proved to be a medicinal edible substance with protective effects against alcoholic liver injury, however, its poor hydrophilicity and permeability have hindered the clinical application of Tax. In this study, we prepared taxifolin-phosphatidylcholine/sodium deoxycholate/PVP-K30 micells (Tax-MLs). Box-Behnken test was used to obtain the optimal preparation process, and Tax-MLs were characterised by transmission electron microscopy and fourier transform infrared spectroscopy. Physicochemical parameters such as proximate micelle concentration, equilibrium solubility and oil-water partition coefficient were determined, and the release pattern of Tax-MLs was investigated by in vitro digestion simulation. Alcoholic liver injury model to explore the in vivo efficacy of Tax-MLs. The results showed that the average particle size, polydispersity index (PDI) and zeta potential of Tax-MLs were 36.90 ± 4.57 nm, 0.194 ± 0.01 and -32.6 ± 0.35 mV, respectively, and the uniform size and distribution of Tax-MLs were observed by transmission electron microscopy. The formation of Tax-MLs was proved by differential scanning calorimetry and fourier transform infrared spectroscopy. In terms of physicochemical properties, the solubility of Tax-MLs in water increased by 92.02 times compared with Tax, and its oil-water partition coefficient in water increased from 0.43 to 1.14, which proved that Tax-MLs could improve its solubility and permeability. The in vivo pharmacodynamic results showed that compared with the Tax group, Tax-MLs low, medium and high dose groups showed a significant reduction in liver indices and serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (P < 0.05), and enhanced the activities of superoxide dismutase (SOD) and glutathione (GSH), and lowered the levels of malondialdehyde (MDA) more significantly in the hepatic tissues. Tax-MLs effectively improved drug solubility and permeability, and enhanced the protective effect against alcoholic liver injury. Animal experiments were conducted with approval from the Animal Ethics Committee of Changchun University of Traditional Chinese Medicine (approval number: 2023601).

Objective:To explore the application value of simultaneous monitoring of voriconazole(VRCZ)and voriconazole N-oxide(VNO)in efficacy and safety of VRCZ in the prevention and treatment of fungal infections in allogeneic hematopoietic stem cell transplantation(allo-HSCT)patients before engraftment(i.e.,days+1 to+30 after transplantation).Methods:The influencing factors of VRCZ,VNO concentration and MR(CVNO/CVRCz)and the difference of VRCZ in the prevention and treatment of fungal infection and liver and kidney injury were analyzed.The receiver operating characteristic curve(ROC)was used to analyze the differences(the corresponding to the maximum of the Youden index on the curve was set as the cut-off value)to confirm the critical value.Results:The factors affecting VRCZ concentration(CVRCZ),VNO concentration(CVNO)and MR were patient weight,VRCZ daily dose,and transplantation type(all P＜0.05).CVRCZ and CVNO in the effective group were higher than those in the ineffective group(P＜0.001),the opposite of MR(P＜0.001);the liver and renal injury group had lower MR than the normal group(P＜0.05).ROC showed that CVRCZ,CVNO and MR had important value in predicting VRCZ in the prevention and treatment of invasive fungal infections in allo-HSCT patients before engraftment,and their cutoff of concentrations were 0.95 μg/ml,1.35 μg/ml and 1.645,respectively(AUC:0.9677,0.7634,0.9564).CVRCZ and MR can assist in indicating liver[cutoff values:0.65 μg/ml,1.96(AUC:0.5971,0.6663)]and renal injury[cutoff values:0.95 μg/ml,1.705(AUC:0.6039,0.6164)].Conclusion:The great value of simultaneous monitoring of VRCZ,VNO and MR can predict in the efficacy and safety of VRCZ in allo-HSCT patients before engraftment.The prediction accuracy of CVRCZ was higher than that of MR,followed by that of CVNO.Increased CVRCZ and decreased MR increase the risk of liver and kidney injury.

Objective:To systematically estimate the effectiveness of physical activity intervention and Borg perceived exertion on the prevention of gestational diabetes mellitus (GDM), and to provide references for physical activity management during pregnancy.Methods:Databases such as PubMed, Cochrane Library Central Register of Controlled Trails, EMBASE, Scopus, CNKI and Wanfang were searched to collect randomized controlled trials (RCT) focusing on the effect of physical activity intervention on glucose control and pregnancy outcomes in pregnant women. The primary outcome was the incidence of GDM. The secondary outcomes included the 2 hour oral glucose tolerance test (2 h OGTT), gestational weight gain, gestational week of delivery, and neonatal weight. The statistical analysis was performed by R 4.0.2 software. The quality of the literatures was evaluated based on the Cochrane Risk of bias tool.Results:A total of 14 RCTs involving 4 509 participants were included in this meta-analysis. The results of meta-analysis showed that the incidence of GDM ( RR=0.74, 95% CI=0.59-0.93, P<0.01), 2 h OGTT (MD=-0.27, 95% CI=-0.48--0.07, P<0.01), and gestational weight gain (MD=-1.04, 95% CI=-1.91--0.18, P=0.02) in the experimental group were all significantly lower than those in control group, while the neonatal weight (MD=-27.43, 95% CI=-58.77-3.92, P=0.09) and gestational week of delivery (MD=-0.18, 95% CI=-0.93-0.57, P=0.64) showed no significant difference between the two groups. Subgroup analysis showed that Borg rating scale of perceived exertion scored higher than 12 ( RR=0.64, 95% CI=0.46-0.89, P<0.01), physical activity conducted in groups ( RR=0.66, 95% CI=0.46-0.94, P=0.02), intervention organized by fitness specialist ( RR=0.73, 95% CI=0.56-0.95, P=0.02) were associated with the decreased risk of GDM. In addition, the meta-regression result showed that total intervention time more than 2 hours per week (correlation coefficient=-1.06, 95% CI=-1.86--0.27, P<0.01) was the main source of study heterogeneity. Conclusions:Physical activity during pregnancy with Borg rating scale of perceived exertion scored higher than 12 had a positive effect on reducing the incidence of GDM.

Objective:To explore the practical effect of applied talent training model based on the"Four Combinations"among students majoring in Traditional Chinese Medicine in a Medical College.Methods:The undergraduate students majoring in Traditional Chinese Medicine at a medical college from grade 2021 and 2022 were selected as the research subjects and divided into two groups.Experimental group were students who had participated in various extracurricular competitions and innovation and entrepreneurship projects,while control group were students who had not participated in any competitions or projects.The final intellectual education scores of the two groups of students were compared(excluding the scores of Marxist basic principles).A questionnaire survey was conducted on the satisfaction of talent cultivation models among the above undergraduate students,and the validity and satisfaction analysis of the survey results were conducted.Results:The experimental group had significantly higher intellectual education scores than the control group(P＜0.05).The results of factor analysis indicated that the sample suitability and the questionnaire validity seem plausible(KMO=0.874).The overall satisfaction score of students towards the"Four Combinations"talent cultivation model was 4.16±0.2(out of 5),reflecting their high recognition of the model.Conclusion:The construction of a"Four Combinations"characteristic Traditional Chinese Medicine applied talent cultivation model is beneficial for improving the quality of cultivating high-quality and composite applied talents in Traditional Chinese Medicine,so as to provide high-quality applied talents with solid theoretical foundation and practical innovation capabilities for the Liaoshen region.

Objective To study the effects of intramedullary pressure on the fluid flow behavior in bones.Methods Multi-scale models of macro bone tissue and macro-meso osteon groups were established using the COMSOL Multiphysics software.Considering the interrelationship of different pore scales,such as the bone marrow cavity,Haversia canal,and bone lacunar-canaliculus,the pore pressure and flow rate of hollow bone tissues and bone tissues with intramedullary pressure were compared,and the effects of the amplitude and frequency of intramedullary pressure on the pressure and flow velocity of the liquid in the bone were analyzed.Results When intramedullary pressure was considered,the pore pressure in bone tissues with intramedullary pressure was 6.4 kPa higher than that in hollow bone tissues.The flow pressure increased significantly with an increase in the intramedullary pressure amplitude,but the flow velocity remained unchanged.The frequency of intramedullary pressure had little effect on pore pressure and flow velocity.Conclusions The multi-scale pore model established in this study can accurately analyze bone fluid flow behavior.These results are of great significance for an in-depth understanding of force conduction in the bone.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the value of single-phase gonadotropin releasing hormone(GnRH)stimulation test in the diagnosis of central precocious puberty(CPP)in girls with different levels of body mass index(BMI).Methods A retrospective analysis was performed for the data of 760 girls with breast development before 7.5 years of age who attended the Third Affiliated Hospital of Zhengzhou University from January 2017 to August 2023.According to the results of GnRH stimulation test and clinical manifestations,they were divided into a CPP group(297 girls)and a non-CPP group(463 girls).According to the values of BMI,the girls were divided into a normal weight group(540 girls),an overweight group(116 girls),and an obese group(104 girls).The receiver operating characteristic(ROC)curve was used to investigate the value of single-phase GnRH stimulation test in the diagnosis of CPP in girls with different levels of BMI.Results Luteinizing hormone(LH)/follicle-stimulating hormone at 30 minutes after GnRH stimulation had an area under the curve(AUC)of 0.985 in the diagnosis of CPP,which was higher than the AUC at 0,60,and 90 minutes(P<0.05).LH at 30 minutes had a similar diagnostic value to LH at 60 minutes(P>0.05).LH at 30 minutes was negatively correlated with BMI and BMI-Z value(P<0.05).The AUC for diagnosing CPP in normal weight,overweight,and obese girls at 30 minutes LH was 0.952,0.965,and 0.954,respectively(P<0.05).Conclusions The 30-minute GnRH stimulation test has a good value in the diagnosis of CPP in girls with different levels of BMI and is expected to replace the traditional GnRH stimulation test,but the influence of BMI on LH level should be taken seriously.

Objective:To investigate the iodine nutritional status of pregnant women in Jilin Province and its correlation with the distribution characteristics of water iodine in external environment, providing a basis for scientific iodine supplementation and prevention of iodine deficiency disorders.Methods:A retrospective analysis was conducted on the iodine survey data of drinking water for residents in Jilin Province in 2017 and the monitoring data of iodine deficiency disorders in 2021. The water iodine, salt iodine, and urinary iodine level of pregnant women were analyzed.Results:In 8 866 water samples from 873 townships (streets, hereinafter referred to as townships) of 60 counties (cities, districts) in 9 cities (autonomous prefectures) throughout the province, the median of water iodine was 4.60 μg/L, ranging from 0.00 to 81.30 μg/L. Among them, there were 758 townships with a median water iodine < 10 μg/L, accounting for 86.83% (758/873); 107 townships with a water iodine of 10 - < 40 μg/L, accounting for 12.26% (107/873). The median salt iodine was 23.50 mg/kg in 6 000 household consumption salt samples. The iodized salt coverage rate, iodized salt qualified rate, and qualified iodized salt consumption rate were 99.50% (5 970/6 000), 97.30% (5 809/5 970), and 96.82% (5 809/6 000), respectively. The iodized salt coverage rate in 9 cities (autonomous prefectures) were > 95%, the iodized salt qualified rate and qualified iodized salt consumption rate were > 90%. The median urinary iodine in 6 000 pregnant women's urine samples was 169.05 μg/L. Except for Bayshan City, which was iodine-deficient, the other 8 cities (autonomous prefectures) were iodine-suitable. The results of correlation analysis showed that there was no correlation between the urinary iodine level of pregnant women and the distribution of water iodine in the external environmental at the municipal (autonomous prefecture) level ( r = 0.60, P = 0.089). Conclusions:Most townships in Jilin Province are iodine-deficient in the external environment, and there are no water-borne high iodine area. The iodized salt coverage rate, iodized salt qualified rate, and qualified iodized salt consumption rate all meet the national standards. The iodine nutrition of pregnant women is generally at a suitable level, but there are still some areas where pregnant women are iodine-deficient, and there is no correlation with the distribution of water iodine.
