AIM: To compare the efficacy of highly aspherical lenslets(HAL), defocus incorporated multiple segments(DIMS), and single-vision spectacle lenses(SVL)in slowing myopia progression in children and adolescents.

METHODS: In this retrospective cohort study, myopic children and adolescents aged 6-16 y who were prescribed spectacle lenses at the hospital between January 2023 and June 2023 were included. Participants were divided into the HAL, DIMS, and SVL groups according to the correction modality voluntarily selected by participants and their guardians. The follow-up duration was 12 mo. After 12 mo of wear, changes from baseline in sphere, cylinder, spherical equivalent(SE), axial length(AL), flat corneal curvature(K1), steep corneal curvature(K2), mean corneal curvature, and binocular visual function \〖binocular cross-cylinder(BCC), negative/positive relative accommodation(NRA/PRA)\〗 were compared among the three groups after 12-month spectacle wear. Three groups were further stratified by age into age≤10 y and age>10 y subgroups to explore the effect of age on myopia control efficacy of defocus lenses.

RESULTS: A total of 159 myopic participants(159 eyes; only the right eye was included for each subject)were enrolled. In the HAL group(55 participants), there were 24 males and 31 females, with a mean age of 10.07±2.14 y. The DIMS group consisted of 60 participants(33 males, 27 females), with a mean age of 10.02±1.88 y. The SVL group included 44 participants(21 males, 23 females), with a mean age of 10.59±1.93 y. There were no significant differences in K1, K2, mean corneal curvature, NRA, BCC, and PRA among the three groups after 12-month spectacle wear(all P>0.05). There were statistically significant differences in the changes in sphere, SE, and AL(all P<0.05). The changes in sphere, cylinder, SE, and AL in the HAL and DIMS groups were significantly lower than those in the SVL group(all P<0.0167). The DIMS group showed a significantly smaller cylinder progression than the SVL group(P<0.0167). In participants aged≤10 y, the change in spherical power in the HAL group was significantly smaller than those in the DIMS group and SVL group after 12-month spectacle wear(all P<0.0167). The change in cylindrical power in the DIMS group was smaller than that in the SVL group(all P<0.0167). Among participants aged>10 y, the changes in spherical power, SE, and AL in both the HAL group and DIMS group were significantly smaller than those in the SVL group after 12-month spectacle wear(all P<0.0167).

CONCLUSION: Both HAL and DIMS lenses can effectively slow the progression of refractive error and AL elongation in children and adolescents, without significant adverse effects on binocular visual function. Among children≤10 y, HAL lenses yield superior spherical power control, whereas DIMS lenses provide better astigmatism control than SVL.

Objective To explore the application effect of bedside critical ultrasound in volume management of acute kidney injury(AKI)donors.Methods Clinical data of 56 AKI donors and 106 recipients from the Transplantation Center of People's Hospital of Guangxi Zhuang Autonomous Region from October 1,2020 to May 31,2022 were collected.They were divided into the critical ultrasound group(34 donors,66 recipients)and the traditional central venous pressure(CVP)group(22 donors,40 recipients)according to the volume management methods.The AKI stage and recovery time,renal function indicators(serum creatinine(Scr),cystatin C,estimated glomerular filtration rate),donor Remuzzi score,cold ischemia time,biventricular inotrope usage rate and time,delayed graft function(DGF)incidence and recovery time,and renal function indicators at 6 and 12 months after surgery were compared and analyzed between the two groups.Results There were no statistically significant differences in gender,age,body weight,AKI stage,pre-acquisition renal function indicators,biventricular inotrope usage rate,renal function indicators at 6 and 12 months after surgery,DGF recovery time,donor Remuzzi score and cold ischemia time of the donors and recipients between two groups(all P>0.05).The AKI recovery time,continuous renal replacement therapy rate and biventricular inotrope usage time of donors in the critical ultrasound group were shorter or lower than those in the traditional CVP group(all P<0.05).The incidence of DGF in recipients of the critical ultrasound group was lower than that of the traditional CVP group(P<0.05).Subgroup analysis showed that there was no statistically significant difference in Scr at 6 and 12 months after surgery in recipients of the critical ultrasound group(P>0.05),while the Scr at 12 months after surgery was higher than that at 6 months in recipients of the traditional CVP group(P<0.05).Conclusions AKI kidneys may be used for kidney transplantation after active maintenance.Bedside critical ultrasound has unique advantages in volume management of AKI donors and may improve the function of AKI kidneys to a certain extent.

Uterine arteriovenous fistula (UAVF), a relatively rare vascular anomaly, may lead to life-threatening hemorrhage and poses diagnostic and management challenges for primary hospitals during initial encounters. This article reports four cases of UAVF treated with Drospirenone and ethinyl estradiol tablets at Department of Gynaecology, Zhuji Maternal and Child Health Hospital between 2023 and 2024. Combined with literature review, we systematically analyzed the etiological mechanisms, clinical characteristics, and diagnostic-therapeutic strategies of this condition, with particular focus on evaluating the efficacy and safety of conservative pharmacological management. By summarizing case features and individualized treatment protocols, this study aims to provide clinical references for early identification, accurate diagnosis, and rational intervention of UAVF, thereby reducing risks of massive hemorrhage and long-term complications while improving patient prognosis.

OBJECTIVE To explore the potential mechanism of Cigu Xiaozhi Prescription(CGXP)in the treatment of non-alco-holic steatohepatitis(NASH)liver fibrosis.METHODS A NASH mouse model was established.The degree of liver enlargement was evaluated by calculating the liver index.Hematoxylin-eosin(HE)and Masson staining were used to observe the degree of liver fibro-sis.In addition,immunohistochemistry was employed to detect the expression of liver fibrosis-related proteins,including α-SMA,Collagen 1,MMP2,and MMP9.Western blot and qPCR techniques were used to detect the expression levels of HIF-1α,E-cadher-in,N-cadherin,Shh,Smo,Gli1,and Gli2 in the mouse liver.The alkaline hydrolysis method was used to measure the content of liv-er hydroxyproline.RESULTS CGXP could effectively reduce the liver index(P<0.001),alleviate liver enlargement and inflamma-tion,and significantly improve the pathological damage of liver tissue in mice with liver fibrosis.CGXP significantly decreased the ex-pression levels of liver fibrosis-related proteins α-SMA,Collagen 1,MMP2 and MMP9(P<0.01,P<0.000 1);reduced the levels of HIF-1α,E-cadherin,N-cadherin,Shh,Smo,Gli1,and Gli2,and the therapeutic effect of high-dose CGXP was particularly significant(P<0.05,P<0.01,P<0.001,P<0.000 1).CONCLUSION CGXP can relieve NASH liver fibrosis in mice by reducing the liver index,alleviating inflammation,and improving tissue pathological damage.The mechanism may be related to the inhibition of the Hedgehog signaling pathway,which alters the activation and proliferation of hepatic stellate cells and reduces the synthesis and dep-osition of extracellular matrix.

Objective:To investigate the neuroprotective effect of nicotinamide riboside(NR)on experimental autoimmune en-cephalomyelitis(EAE)mice.Methods:C57BL/6 female mice were induced by myelin oligodendrocyte glycoprotein(MOG35-55)to pro-duce EAE model and were randomly divided into EAE group and NR group.From day 3 to day 27 after immunization,each mouse in EAE group was given normal saline(200 μl/d)and each mouse in NR group was given NR(500 mg/kg,200 μl/d)by intragastric administration.Clinical score and body weight of mice in EAE group and NR group were recorded every day.On the 28th day after immunization,the spinal cord protein of mice in each group was extracted and the frozen sections of spinal cord of mice in each group were prepared.LFB staining was used to detect demyelination,immunofluorescence staining was used to detect the expression of MAP-2 and the number of positive cells of NeuN,BDNF,GDNF,NGF and NT-3,and Western blot was used to detect the expressions of BDNF,GDNF,NGF and NT-3 of spinal cord.Results:Compared with EAE group,NR significantly delayed the onset time of EAE mice(P<0.05),decreased clinical score(P<0.05),reduced weight loss,alleviated spinal cord demyelination(P<0.05),increased the expression of MAP-2(P<0.01)and the number of NeuN positive cells(P<0.01),and up-regulated the expressions of BDNF,GDNF,NGF and NT-3(P<0.05).Conclusion:NR shows a good neuroprotective effect on EAE mice.The mechanism may be related to NR significantly increasing the expression of spinal neurotrophic factors,improving the microenvironment of the central nervous sys-tem,nourishing nerves,promoting nerve repair and nerve growth,etc.

Objective:To explore the mechanisms of oxaliplatin resistance mediated by TET2 methylation in the treatment of acute lymphoblastic leukemia (ALL) using bioinformatics methods.Methods:The data on drug-resistant and sensitive cell lines related to oxaliplatin treatment for ALL were download using the Genomics of Drug Sensitivity in Cancer (GDSC) database (updated in December 2023); the drug-resistant cell lines were screened based on half maximal inhibitory concentration ( IC50) > 10 μmol/L, and the difference in IC50 between drug-resistant and sensitive cell lines were analyzed using Mann-Whitney U test. The cancer driver mutation genes in drug-resistant cell lines were retrieved using the Cancer Cell Line Encyclopedia (CCLE) database (updated in December 2023). Using the protein-protein interaction (PPI) network functional enrichment analysis (STRING) database (updated in June 2024), PPI network analysis was performed on cancer driver mutation genes with biological functions. A confidence threshold of ≥ 0.7 (high confidence) and an average network node degree above 4 (high average) were selected to screen for cancer driver mutation genes with significant biological functions. Using the microRNA Data Integration Portal (mirDIP) database (updated in June 2024), the coexpression data of microRNA (miRNA) and mutant target genes were queried, miRNA-target gene pairs were screened according to the highest score threshold of 1% miRNA and interaction score > 0.9, and the regulatory effect of miRNA on mutant genes was analyzed. DNA methylation data were download from the Methylation in Human Cancer (MethHC) database (updated in June 2024) and the methylSig R software package was used to analyze the differentially methylated regions (DMR) of DNA methylation between drug-resistant and sensitive cell lines; genes with P < 0.05 and absolute difference > 0.2 were selected, and they were divided into high methylation gene group and low methylation gene group. Spearman correlation analysis and Spearman rank test were performed for the degree of methylation and gene expression, and the key genes with P < 0.01 were screened to reveal the relationship between methylation degree and gene expression. Results:As a result of searching the GDSC database, there were a total of 9 drug-resistant cell lines and 17 sensitive cell lines related to oxaliplatin treatment for ALL; after Z-score normalization of IC50 data between drug-resistant and sensitive cell lines, the average rank of drug-resistant cell lines was 21, and the average rank of sensitive cell lines was 8.5, with a statistically significant difference ( Z = -4.08, P < 0.01). Eight cancer driver mutation genes with significant biological functions that lead to drug resistance of the cell lines were screened using the CCLE database and STRING database. According to the mirDIP database, there were a total of 12 pairs of miRNA-target gene pairs with miRNA-target gene interaction scores >0.9. miRNA had strong regulatory effects on the expressions of NRAS and MAP2K1 target genes. In the MethHC database, the β values (numerical value of increased methylation level) of DMR for genes such as TP53, RXRG and SGIP in drug-resistant cell lines were 0.151, 0.165 and 0.149, respectively, compared to those in sensitive cell lines, the differences were statistically significant (all P < 0.01). The degree of methylation of SGIP gene was negatively correlated with the relative expression level of SGIP mRNA ( r = -0.71, P < 0.01), and SGIP gene underwent high methylation at promoter site 143886940. The cg08321569 locus in the TET2 gene domain of drug-resistant cell lines exhibited persistent high methylation, with a methylation level of β = 0.89. This locus was located 1.2 kb downstream of the transcription start point of exon 4, and the degree of TET2 methylation was negatively correlated with the relative expression level of TET2b mRNA ( r = -0.81, P < 0.01). Conclusions:TET2 methylation may be an important factor for oxaliplatin resistance in the treatment of ALL.

ObjectiveTo assess the level of health literacy and its influencing factors among middle school students aged 12‒18 years in Jing’an District, Shanghai, so as to provide a solid scientific foundation for further developing more targeted intervention measures. MethodsA stratified cluster random sampling method was used to randomly select 4 middle schools in Jing’an District, Shanghai from November to December 2023, and conducted a health literacy questionnaire survey on non-graduating middle and high school students, respectively. The2023 Survey on the Status of Health Literacy among Middle School Students in Jing’an District, Shanghai was adopted, which consisted of two parts: health literacy and basic information. Health literacy was divided into three dimensions: health knowledge and concept literacy, healthy lifestyle and behavior literacy, and health skill literacy. Three dimensions could be categorized into six types of health literacy issue: scientific health literacy, infectious disease prevention and control literacy, chronic disease prevention and control literacy, safety and first aid literacy, basic health literacy, and health information literacy. ResultsA total of 1 161 middle school students were enrolled into this study, including 571 males and 570 females. The overall health literacy level of middle school students was 33.51%, with 34.81% among middle school students and 31.69% among high school students, respectively. Results of logistic regression analysis showed that health knowledge acquisition and awareness, as well as application frequency of health knowledge, were the influencing factors for the overall health literacy level among middle school students (P<0.05). The degree of family attention to health maintenance, health knowledge acquisition and awareness, and application frequency of health knowledge were the main influencing factors for the three dimensions and literacy of six types of health issues among middle school students (P<0.05). ConclusionThe levels of different types of health literacy among middle school students in Jing’an District are uneven, with the highest being safety and first aid literacy and the lowest being basic health literacy. It is recommended to take targeted measures to comprehensively improve the health literacy level of middle school students.
