Objective: To analyze the trajectories of blood pressure and body mass index (BMI) among primary and secondary school students aged 7-17 in Shunyi District of Beijing, and to explore the association between different growth trajectories and visual outcomes, so as to provide a scientific basis for the prevention and control of common diseases in children and adolescents. Methods: Health examination data (including vision, blood pressure and BMI) of primary and secondary school students in Shunyi District of Beijing from 2019 to 2023 were collected and analyzed. Group based trajectory modeling was used to classify the trajectories of BMI and blood pressure (systolic and diastolic) into distinct groups among students aged 7-17 years. The relationship between these trajectories and visual outcomes was examined using binary Logistic regression analysis. Results: The prevalence of screening myopia among students in Shunyi District was 57.2%, while the rate of moderate to severe visual impairment was 55.8%. Based on the latent growth model, the trajectories of systolic blood pressure, diastolic blood pressure, and BMI were divided into three groups:low growth trajectory, moderate growth trajectory and high maintenance trajectory. Logistic regression analysis revealed that, compared to the low growth trajectory group, the moderate growth and high maintenance trajectory groups for systolic blood pressure, diastolic blood pressure, and BMI were associated with an increased risk of screening myopia ( OR =1.14, 1.11; 1.07, 1.19 ; 1.06, 1.08, P <0.05). Similarly, the moderate growth and high maintenance trajectory groups for systolic blood pressure, diastolic blood pressure, and BMI were similarly associated with an increased risk of moderate to severe visual impairment ( OR = 1.12 , 1.12; 1.09, 1.17; 1.08, 1.11, P <0.05). Conclusions Moderate growth and high maintenance trajectories of blood pressure and BMI are associated with an increased risk of screening myopia and moderate to severe visual impairment among students. It is recommended to closely monitor changes in blood pressure and overweight/obesity trajectories in primary and secondary school students, conduct regular assessments, and actively prevent the development and progression of multimorbidity and comorbidity.

A domestically produced self-expanding transcatheter aortic valve controllable bending delivery system(VitaFlow? Ⅲcontrollable bending retrievable delivery system)was first used to perform transcatheter aortic valve replacement(TAVR)in a symptomatic severe aortic valve stenosis patient with severe heart failure and high risk of surgery in China on September 22,2023.The patient successfully completed TAVR under general anesthesia,with good valve position and function after the operation.Before discharge and at one month of follow-up,the patient's symptoms and degree of heart failure were significantly improved.The follow-up results of this case showed that the VitaFlow? Ⅲ controllable bending retrievable delivery system for TAVR is safe and feasible,and future prospective,multicenter clinical trials are expected to evaluate its efficacy.

Aflatoxin B1(AFB1)is a secondary metabolite produced by Aspergillus aflatoxin and Aspergillus parasiticus.It has strong immunotoxicity and carcinogenicity and seriously harms the health of humans and livestock.Therefore,this study aims to explore the effect of selenomethionine(SeMet)in alleviating AFB1-induced thymic damage.Fifty 35-day-old rabbits were randomly divid-ed into 5 groups,with 10 rabbits in each group.They are the control group,AFB1 group,AFB1+0.2Se group(0.2 mg/kg SeMet),AFB1+0.4Se group(0.4 mg/kg SeMet)and AFB1+0.6Se group(0.6 mg/kg SeMet).The test period was 21 d.On the 17th day,each rabbit in the AFB1 group and each SeMet group was gavaged with AFB1(0.3 mg/kg)every day for 5 consecutive days.Rabbit thymus tissue was taken for HE,TUNEL and PCNA detection.ELISA was used to detect the ex-pression of inflammatory factors in thymus tissue,and GSH-Px,T-AOC and MDA kits were used to detect oxidative stress indicators in thymus tissue.The results showed that AFB1 exposure caused a very significant increase in MDA levels in rabbit thymus tissue by 116.04％,and a signifi-cant decrease in the activities of antioxidant enzymes GSH-Px and T-AOC by 29.20％and 52.17％respectively.In addition,AFB1 induced an inflammatory response in the thymus,promoting TNF-a secretion to increase by 124.71％,IL-6 by 174.72％,and IL-1β by 62.38％compared with the con-trol group.SeMet pretreatment significantly improved the pathological changes of the thymus in rabbits and reduced its oxidative stress and inflammatory response.Therefore,we confirmed that SeMet alleviates AFB1-induced thymic damage and improves the immune performance of rabbits.

ObjectiveTo establish a quantitative analysis multi-components by single marker method （QAMS） for five main components （aucubin， geniposidic acid， chlorogenic acid， asperuloside and rutin） in Eucommiae Folium， to verify its feasibility and applicability in the determination of Eucommiae Folium， so as to provide a scientific basis for the development of quality standard of this herb. MethodHigh performance liquid chromatography was performed on a Welch Boltmatetm™ C₁₈ column （4.6 mm×100 mm， 2.7 μm） with methanol （A）-0.2% phosphoric acid aqueous solution （B） as the mobile phase for gradient elution （0-8 min， 3%A； 8-10 min， 3%-11%A； 10-26 min， 11%A； 26-27 min， 11%-25%A； 27-60 min， 25%-32%A）， the column temperature was set at 30 ℃， the flow rate was 0.6 mL·min^-1， the detection wavelengths were at 210 nm and 254 nm. Chlorogenic acid was used as an internal reference to establish the relative correction factors （f） between it and the other four components， and the contents of the five components in 14 batches of Eucommiae Folium were determined by QAMS and external standard method （ESM）， respectively. ResultThe f values of chlorogenic acid to aucubin， geniposidic acid， asperuloside and rutin were 3.13， 1.45， 2.64 and 0.56， respectively. Repeatability was good under different experimental conditions， relative standard deviation （RSD） was <5.0%. The contents of aucubin， geniposidic acid， chlorogenic acid， asperuloside and rutin in 14 batches of Eucommiae Folium were 1.340-28.975， 0.252-36.086， 10.016-27.443， 1.396-8.646， 0.533-1.766 mg·g^-1， respectively. There were no significant difference between content results of QAMS and that of ESM （RSD<5.0%）. ConclusionQAMS established with chlorogenic acid as the internal reference can be used to determine the contents of five components in Eucommiae Folium， and this method is simple and accurate. After comprehensive evaluation， the quality standard of Eucommiae Folium in subsequent editions of Chinese Pharmacopoeia is suggested that three main active components， chlorogenic acid， aucubin and geniposidic acid， are selected as quality markers， and their content limits are recommended not less than 1.5%， 1.0% and 1.0%， respectively. This quality standard draft can avoid the potential quality risk due to poor specificity and low content limit of the index component （chlorogenic acid） in the previous editions of Chinese Pharmacopoeia.

ObjectiveTo prepare matrine lipid-based cubic liquid crystalline nanoparticle （MAT-LLCN） gels and investigate its in vitro release and transdermal absorption behavior. MethodTaking entrapment efficiency as the index， the optimal formulation of MAT-LLCN was screened by extreme vertex mixture method based on the optimal ratio of glycerol monooleate （GMO） to poloxamer 407 （P407）， and its drug loading was investigated. MAT-LLCN gels was prepared by mixing MAT-LLCN with pre-swelled carbomer 940 as the gel matrix. The structure of MAT-lipid-based cubic liquid crystalline （LLC） was characterized by polarized light microscopy （PLM） and small angle X-ray scattering （SAXS）. The in vitro release and transdermal absorption properties of MAT-LLCN gels and MAT ordinary gels were compared by modified Franz diffusion cell method， skin structure changes caused by them were observed by hematoxylin-eosin （HE） staining. ResultThe optimal formulation of MAT-LLCN gels was 5.5% of GMO-P407 （9∶1）， 1%-6% of MAT， 0.6% of carbomer 940， adding water to sufficient amount. The prepared MAT-LLC was confirmed as body-centered （Im3m） LLC. The in vitro release behavior of MAT-LLCN gels was in accordance with the Weibull equation （R²=0.954 0）， and the release mechanism was the Fick diffusion. In vitro transdermal test showed that all the parameters of MAT-LLCN gels were higher than those of MAT ordinary gels （P<0.05）， including cumulative release rate， steady-state release rate and the amount of drug retention in skin. HE staining results showed that MAT-LLCN gels could loose the cellular arrangement of skin stratum corneum， and maintain the stability of the cell structure of the dermis. ConclusionThe prepared MAT-LLCN gels can accelerate the transdermal drug transport and form drug storage in the dermis by rapidly opening the skin stratum corneum barrier， suggesting that LLC has good application prospects in the field of transdermal drug delivery.

Objective:To externally validated the intra-aortic balloon pump (IABP) shockⅡ score and CardShock score for predicting in-hospital mortality in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS) and compared them with the Acute Physiology and Chronic Health EvaluationⅡ (APACHEⅡ) score.Methods:According to the inclusion and exclusion criteria, patients admitted to the cardiac care center (CCU) of our center from December 2010 to May 2019 were enrolled in this study. Patients’ baseline characteristics, in-hospital interventions, and outcomes were collected. The APACHEⅡ score was calculated during hospitalization by clinicians and collected by researchers. Two researchers independently calculated the IABP-ShockⅡ score and CardShock score; any disagreement was discussed with the third researcher. The performance of risk scores was evaluated by discrimination and calibration. The discriminative ability of risk scores was evaluated using the area under the receiver operating characteristic curve (AUC) and compared by the Delong method. The calibration of these risk scores was examined by the Hosmer-Lemeshow goodness-of-fit test. The calibration plot was also built.Results:A total of 150 patients enrolled in our study, and the in-hospital mortality was 60%. According to the IABP-ShockⅡ score, patients scored as low risk (0-2), moderate risk (3-4), and high risk (5-9) had in-hospital mortality of 29%, 68%, and 80%, respectively. According to the CardShock score, patients scored as low risk (0-3), moderate risk (4-5), and high risk (6-9)had in-hospital mortality of 21%, 57%, and 82%, respectively. According to the APACHEⅡ score, patients scored<20, 20-30, and >30 had in-hospital mortality of 19%, 69%, and 93%, respectively. For predicting the in-hospital mortality, the APACHEⅡ score demonstrated excellent discrimination (AUC=0.90, 95% CI: 0.84-0.95). The IABP-ShockⅡ score and CardShock score showed good discrimination (AUC=0.76, 95% CI: 0.68-0.83 and AUC=0.79, 95% CI: 0.72-0.85). The discriminative ability did not significantly differ between the IABP-ShockⅡ score and the CardShock score (0.76 vs 0.79, P>0.05), but both of which were significantly lower than the APACHEⅡ score (0.76 vs 0.90, P<0.05, and 0.79 vs 0.90, P<0.05). At the same time, it was not significantly different between the IABP-ShockⅡ score and the CardShock score (0.76 vs 0.79, P>0.05). All of these three scores were adequately calibrated according to the Hosmer-Lemeshow goodness-of-fit test ( P>0.05).The calibration plot showed accurate calibration of these three scores. Conclusions:Although less accurate than the APACHEⅡ score, the IABP-ShockⅡ score and CardShock score can show accurate prediction for in-hospital mortality of AMI-CS patients.
