IOL power calculation methods have evolved and innovated throughout time, from early theoretical and regression formulas to nonlinear formulas for estimating effective lens position (ELP), multivariable formulas, and innovative formulas that use optical principles and AI-based online formulas. This paper thoroughly discusses the development and iteration of traditional IOL calculation formulas, the emergence of new IOL calculation formulas, and the selection of IOL calculation formulas for different patients in the era of refractive cataract surgery, serving as a reference for “personalized” IOL implantation in clinical practice.展开更多

The refractive error changing rate for the cornea and lens power, the axial length, anterior chamber depth(ACD) and vitreous chamber depth(VCD) are calculated, including nonlinear terms for more accurate rate functions than the linear theory. Our theory, consistent with the empirical data, shows that the Pearson correlation coefficients for spherical equivalent(SE) and ocular components are highest for SE with axial length, ACD and VCD and weakest for corneal power, lens power and lens thickness. Moreover, our regression formulas show the asymmetric feature of the correlation that the axial length, ACD and VCD are more strongly correlated(with higher negative regression constants) with refractive errors in eyes with hyperopia than in eyes with myopia, particularly for severe hyperopia.展开更多

METHODS: Using a radioimmunoassay, we measured total ghrelin concentrations in 19 samples of commercial infant formulas and in 20 samples of human milk. We also determined ghrelin concentration in the serum of infants and lactating mothers. RESULTS: Ghrelin concentrations were significantly higher in artificial milk (2007.1 ± 1725.36 pg/mL) than in human milk (828.17 ± 323.32 pg/mL) (P = 0.005). The mean ghrelin concentration in infant serum (n = 56) was 1115.86 ± 42.89 pg/mL, and was significantly higher (P = 0.023) in formula-fed infants (1247.93 ± 328.07 pg/mL) than in breast-fed infants (1045.7 ± 263.38 pg/mL). The mean serum ghrelin concentration (mean ± SD) in lactating mothers (n = 20) was 1319.18 ± 140.18 pg/mL. CONCLUSION: This study provides evidence that total ghrelin is present in infant formulas. This findingraises diverse questions regarding the uptake, absorption and metabolic effects of this hormone.展开更多

文摘Traditional Chinese medicine formula(TCMF)represents a fundamental component of Chinese medical practice,incorporating medical knowledge and practices from both Han Chinese and various ethnic minorities,while providing comprehensive insights into health and disease.The foundation of TCMF lies in its holistic approach,manifested through herbal compatibility theory,which has emerged from extensive clinical experience and evolved into a highly refined knowledge system.Within this framework,Chinese herbal medicines exhibit intricated characteristics,including multi-component interactions,diverse target sites,and varied biological pathways.These complexities pose significant challenges for understanding their molecular mechanisms.Contemporary advances in artificial intelligence(AI)are reshaping research in traditional Chinese medicine(TCM),offering immense potential to transform our understanding of the molecular mechanisms underlying TCMFs.This review explores the application of AI in uncovering these mechanisms,highlighting its role in compound absorption,distribution,metabolism,and excretion(ADME)prediction,molecular target identification,compound and target synergy recognition,pharmacological mechanisms exploration,and herbal formula optimization.Furthermore,the review discusses the challenges and opportunities in AI-assisted research on TCMF molecular mechanisms,promoting the modernization and globalization of TCM.
文摘As cataract surgery progresses from “restoration of sight” to “refractive correction”, precise prediction of intraocular lens (IOL) power is critical for enhancing postoperative visual quality in patients. IOL power calculation methods have evolved and innovated throughout time, from early theoretical and regression formulas to nonlinear formulas for estimating effective lens position (ELP), multivariable formulas, and innovative formulas that use optical principles and AI-based online formulas. This paper thoroughly discusses the development and iteration of traditional IOL calculation formulas, the emergence of new IOL calculation formulas, and the selection of IOL calculation formulas for different patients in the era of refractive cataract surgery, serving as a reference for “personalized” IOL implantation in clinical practice.

文摘Perchlorate and chlorate are ubiquitous pollutants that can adversely affect the thyroid function in humans.This study assessed the potential health risks associated with the dietary exposure of infants and young children to perchlorate and chlorate present in infant formulas available in Shanghai.The assessment was based on risk monitoring data from 150 samples of infant formulas in Shanghai between 2020 and 2022,along with the dietary consumption data of infants and young children.The detection rates of perchlorate and chlorate in infant formulas were 46.0%and 98.7%,with mean contents of 9.98μg/kg and 112.01μg/kg,and the maximum values of 151.00μg/kg and 1475.00μg/kg,respectively.The mean and 95th percentile(P95)values of daily perchlorate exposure of 0-36-month-old infant and young children via infant formulas were 0.07 and 0.17μg/kg body weight(bw)per day,respectively,which were lower than the tolerable daily intake(TDI)of perchlorate(0.3μg/kg bw per day).The mean and P95 values of chlorate exposure via infant formulas in 0-36-month-old infants and young children were 0.83 and 1.89μg/kg bw per day,which were lower than the TDI of chlorate(3μg/kg bw per day).The P95 exposure of different age groups(0-6 months,7-12 months and 13-36 months)of infants and young children to perchlorate and chlorate in infant formulas was below the TDI.Therefore,the risk associated with the exposure of 0-36-month-old infants and young children to perchlorate and chlorate from infant formulas in Shanghai is considered acceptable.Prioritizing environmental pollution control efforts to reduce the levels of perchlorate and chlorate in food products is important to safeguard the health of the infants and children under the One Health concept.

文摘The multiple regression formulas and correlation of ocular components with refractive errors are presented by Gaussian optics. The refractive error changing rate for the cornea and lens power, the axial length, anterior chamber depth(ACD) and vitreous chamber depth(VCD) are calculated, including nonlinear terms for more accurate rate functions than the linear theory. Our theory, consistent with the empirical data, shows that the Pearson correlation coefficients for spherical equivalent(SE) and ocular components are highest for SE with axial length, ACD and VCD and weakest for corneal power, lens power and lens thickness. Moreover, our regression formulas show the asymmetric feature of the correlation that the axial length, ACD and VCD are more strongly correlated(with higher negative regression constants) with refractive errors in eyes with hyperopia than in eyes with myopia, particularly for severe hyperopia.

文摘AIM:To evaluate the accuracy of eight different intraocular lens(IOL)power calculation formulas for a segmented multifocal IOL.METHODS:A total of 53 eyes of 41 adult cataract patients who underwent phacoemulsification and implantation with the SBL-3 segmented multifocal IOL between January 1,2017 and January 31,2019 were included in this retrospective study.Preoperative biometry measurements were obtained using an IOL Master.Manifest refraction was performed at least 4 wk postoperatively.Accuracy of the eight formulas[Barrett Universal II,Emmetropia Verifying Optical(EVO),Haigis,Hill-RBF 2.0,Hoffer Q,Holladay 1,Kane,and SRK/T]was analyzed.RESULTS:Using current lens constants,all formulas exhibited errors of slight myopic shift in refractive prediction.The Barrett Universal II formula had a significantly lower median absolute error(MedAE)than did Holladay 1(P=0.02),Kane(P=0.001)and Hill-RBF 2.0(P<0.001)formulas.The Haigis formula had a lower MedAE value than did the Hill-RBF 2.0 formula(P=0.005).Differences in MedAE values among SRK/T,EVO and Hoffer Q formulas were not significant.After optimizing lens constants,the MedAE values of all formulas were reduced;significant changes were noted for EVO(P=0.022),Haigis(P=0.048);Hill-RBF 2.0(P=0.014),Holladay 1(P=0.045)and Kane(P=0.022)formulas.All formulas performed equally well after optimization of lens constants(P=0.203).CONCLUSION:All eight formulas tend to result in a myopic shift when using current lens constants.Optimized lens constants improve the accuracy of these formulas among adult Chinese patients.

文摘AIM: To test if total ghrelin is present in infant formulas. METHODS: Using a radioimmunoassay, we measured total ghrelin concentrations in 19 samples of commercial infant formulas and in 20 samples of human milk. We also determined ghrelin concentration in the serum of infants and lactating mothers. RESULTS: Ghrelin concentrations were significantly higher in artificial milk (2007.1 ± 1725.36 pg/mL) than in human milk (828.17 ± 323.32 pg/mL) (P = 0.005). The mean ghrelin concentration in infant serum (n = 56) was 1115.86 ± 42.89 pg/mL, and was significantly higher (P = 0.023) in formula-fed infants (1247.93 ± 328.07 pg/mL) than in breast-fed infants (1045.7 ± 263.38 pg/mL). The mean serum ghrelin concentration (mean ± SD) in lactating mothers (n = 20) was 1319.18 ± 140.18 pg/mL. CONCLUSION: This study provides evidence that total ghrelin is present in infant formulas. This findingraises diverse questions regarding the uptake, absorption and metabolic effects of this hormone.

文摘In this paper,we derive some∂∂^(-)-Bochner formulas for holomorphic maps between Hermitian manifolds.As applications,we prove some Schwarz lemma type estimates,and some rigidity and degeneracy theorems.For instance,we show that there is no non-constant holomorphic map from a compact Hermitian manifold with positive(resp.non-negative)ℓ-second Ricci curvature to a Hermitian manifold with non-positive(resp.negative)real bisectional curvature.These theorems generalize the results[5,6]proved recently by L.Ni on Kähler manifolds to Hermitian manifolds.We also derive an integral inequality for a holomorphic map between Hermitian manifolds.

文摘Background The coronavirus disease 2019(COVID-19)continues to spread worldwide.Integrated Chinese and Western medicine have had some successes in treating COVID-19.Objective This study aims to evaluate the efficacy and safety of three traditional Chinese medicine drugs and three herbal formulas(3-drugs-3-formulas)in patients with COVID-19.Search strategy Relevant studies were identified from 12 electronic databases searched from their establishment to April 7,2022.Inclusion criteria Randomized controlled trials(RCTs),non-RCTs and cohort studies that evaluated the effects of 3-drugs-3-formulas for COVID-19.The treatment group was treated with one of the 3-drugs-3-formulas plus conventional treatment.The control group was treated with conventional treatment.Data extraction and analysis Two evaluators screened and selected literature independently,then extracted basic information and assessed risk of bias.The treatment outcome measures were duration of main symptoms,hospitalization time,aggravation rate and mortality.RevMan 5.4 was used to analyze the pooled results reported as mean difference(MD)with 95%confidence interval(CI)for continuous data and risk ratio(RR)with 95%CI for dichotomous data.Results Forty-one studies with a total of 13,260 participants were identified.Our analysis suggests that compared with conventional treatment,the combination of 3-drugs-3-formulas might shorten duration of fever(MD=–1.39;95%CI:–2.19 to–0.59;P<0.05),cough(MD=–1.57;95%CI:–2.16 to–0.98;P<0.05)and fatigue(MD=–1.36;95%CI:–2.21 to–0.51;P<0.05),decrease length of hospital stay(MD=–2.62;95%CI–3.52 to–1.72;P<0.05),the time for nucleic acid conversion(MD=–2.92;95%CI:–4.26 to–1.59;P<0.05),aggravation rate(RR=0.49;95%CI:0.38 to 0.64;P<0.05)and mortality(RR=0.34;95%CI:0.19 to 0.62;P<0.05),and increase the recovery rate of chest computerized tomography manifestations(RR=1.22;95%CI:1.14 to 1.3;P<0.05)and total effectiveness(RR=1.24;95%CI:1.09 to 1.42;P<0.05).Conclusion The 3-drugs-3-formulas can play an active role in treating all stages of COVID-19.No severe adverse events related to 3-drugs-3-formulas were observed.Hence,3-drugs-3-formulas combined with conventional therapies have effective therapeutic value for COVID-19 patients.Further long-term high-quality studies are essential to demonstrate the clinical benefits of each formula.
