AIM:To evaluate the clinical efficacy of three types of spectacle lenses with different peripheral microstructure designs in controlling myopia progression among children.METHODS: Retrospective case analysis was conducted. Children diagnosed with myopia aged 6 to 12 y who were received initial spectacle fitting and completed 1-year follow-up at the Optometry Clinic of Suining Central Hospital between January 2023 and August 2024 were enrolled. Only right eye data of all subjects were included for analysis. Based on the type of spectacle lenses independently selected by the children and their parents/guardians, they were divided into four groups: diffusion optics technology(DOT), cylindrical annular refractive element(CARE), highly aspherical lenslets(HAL), and single-vision lenses(SVL). Changes in axial length(AL)and spherical equivalent(SE)from baseline were observed after 1-year lens wear in four groups. Variations between three peripheral microstructure-designed spectacles and single-vision spectacles were compared. The effects of different lens designs on spherical power, astigmatism, corneal curvature, corneal astigmatism, anterior chamber depth, lens thickness, and vitreous cavity depth were analyzed.RESULTS:In this retrospective study, a total of 118 eyes from 118 myopic children were included. There were 28 eyes in 28 children in DOT group [16 males and 12 females, age 10(9, 12)y]. CARE group contained 26 eyes in 26 children, [12 males and 14 females, age 11(9, 12)y]. HAL group had 26 eyes in 26 children [16 males and 10 females, age 10(9, 11)y]. SVL group included 38 eyes in 38 children [20 males and 18 females, age 11(9, 12)y]. There were no significant differences in age, gender, baseline AL, or SE among the four groups(all P>0.05). After 1-year wearing, no increase and slight regression were observed in AL and SE in the DOT group, with no significant differences compared with baseline(all P>0.05). AL and SE increased to varying degrees in the CARE, HAL and SVL groups(all P<0.01). Significant inter-group differences were found in the changes of AL and SE(F=22.820, 30.949, both P<0.001). The mean changes in AL and SE for the DOT group(-0.034±0.180 mm, 0.040±0.243 D)were significantly smaller than those in the CARE group(0.225±0.174 mm, -0.375±0.308 D)and the HAL group(0.147±0.130 mm, -0.255±0.256 D). The changes of AL and SE in the three groups were significantly lower than those in the SVL group(0.355±0.240 mm, -0.891±0.592 D)(all P<0.05).CONCLUSION: In children, short-term wear of spectacles with peripheral microstructural design demonstrates better myopia control efficacy compared to single-vision spectacles. DOT lenses show superior short-term efficacy compared with CARE and HAL lenses.

Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

External apical root resorption is among the most common risks of orthodontic treatment, and it cannot be completely avoided and predicted. Risk factors causing orthodontic root resorption can generally be divided into patient- and treatment-related factors. Root resorption that occurs during orthodontic treatment is usually detected by radiographical examination. Mild or moderate root absorption usually does no obvious harm, but close attention is required. When severe root resorption occurs, it is generally recommended to suspend the treatment for 3 months for the cementum to be restored. To unify the risk factors of orthodontic root resorption and its clinical suggestions, we summarized the theoretical knowledge and clinical experience of more than 20 authoritative experts in orthodontics and related fields in China. After discussion and summarization, this consensus was made to provide reference for orthodontic clinical practice.

Objective To summarize the clinical outcomes of surgical correction of velophary geal insufficiency (VPI) with two procedures of radical intravelar veloplsties,and to discuss the indication selection of surgical technique.Methods 58 cases of various cleft palate were speech evaluated and diagnosed as mild to moderate VPI,who aged from 3 to 28 years (mean age 7.5 years).Group Ⅰ (36 cases) were performed surgery in the way of modified Furlow double-opposing Z-plasty.Group Ⅱ (22 cases) were performed surgery in the way of Sommerald radical IVV.All cases were followed up for 6 months to 1 year after surgery,with speech evaluation and objective examination of nasopharygoscopy and fixed position lateral X ray.The X-ray images of lateral view of velum was read through PACS image system.The effective work length of soft palate and the pharyngeal gap of the velum at rest and function were measured directly through PACS system.The data of each case before and after surgery were compared.Results 34 of 36 cases (94.50％) in modified-Furlow group and 21 of 22 cases (95.5％) in Sommerlad group finally recovered complete velopharyngeal closure.Compared between before and post operation,the effective work length of soft palate in modified Furlow group increased by 9.50±2.35 mm,the length in Sommerlad group increased by 7.50±3.32 mm.The differences were statistically significant by paired T test (P＜0.001).None of all cases complained nasal airway obstruction.Conclusions Both types of radical IVVs are highly effective to be recommended for surgical correction of mild to moderate VPI.Strict selection of surgical indication and excellent surgical skill are necessary for good treatment outcomes.

OBJECTIVE： To investigate the correlation of ADPRT rs1136410 polymorphism with the occurrence of non-small cell lung cancer （NSCLC） in Han nationality from northern Jiangsu. METHODS： A total of 283 patients with primary NSCLC of Han nationality in Northern Jiangsu were selected from the Affiliated Hospital of Xuzhou Medical University during Nov. 2015-Dec. 2018 as NSCLC group. A total of 210 healthy subjects underwent physical examination were included in control group. PCR-RFLP was utilized to determine the genotypes at ADPRT rs1136410 locus. Logistic regression model was used to evaluate the effect of polymorphism and its interaction with smoking on the occurrence of NSCLC. RESULTS： There was no statistical significance in age and gender between 2 groups （P＞0.05）. The proportion of smoker in NSCLC group was significantly higher than control group （P＜0.05）. TT， TC and CC genotypes were detected at rs1136410 locus of ADPRT gene. The frequency of TT， TC and CC genotype were 41.9％，44.8％ and 13.3％， and those of allele T and C were 64.3％ and 35.7％ in control group. The frequency of TT， TC and CC genotype were 21.6％， 50.2％ and 28.2％， and those of allele T and C were 46.6％ and 53.4％ in NSCLC group， respectively. The frequencies of genotypes in 2 groups were in accordance with Hardy-Weinberg equilibrium （P＞0.05）， while there was significant difference in genotype and allele frequencies between 2 groups （P＜0.05）. Compared with TT genotype， the risk of NSCLC in individuals carrying TC and CC genotypes raised by 1.179， 3.122 folds [ORTC＝2.179， 95％CI （1.435， 3.309）， P＜0.05； ORCC＝4.122，95％CI（2.401，7.075），P＜0.05]. Compared with individuals carrying TT genotype， the risk of NSCLC occurrence in non-smokers carrying TC and CC genotypes increased by 0.371， 1.328 fold [ORTC＝1.371，95％CI （0.927，3.428），P＜0.05； ORCC＝2.328，95％CI （1.249，4.622），P＜0.05]； and the risk of NSCLC occurrence in smokers carrying TC and CC genotypes increased by 0.928， 2.182 folds [ORTC＝1.928，95％CI （1.257，2.957）， P＜0.05；ORCC＝3.182，95％CI （1.760，5.754）， P＜0.05]. CONCLUSIONS： The rs1136410 locus mutant genotype of ADPRT gene is the risk factor of NSCLC in Han nationality from Northern Jiangsu， and smoking raises this risk of NSCLC occurrence in individuals with mutation genotypes of ADPRT rs1136410.

Objectives: To explore weather oxygen uptake efficiency slope (OUES) may predict the prognosis in patients with idiopathic pulmonary arterial hypertension (IPAH). Methods: The consecutive newly diagnosed IPAH patients in our hospital from 2010-11 to 2015-06 were prospectively enrolled and regular follow-up study was conducted to record cardiovascular events (death and lung transplantation). Kaplan–Meier curve, uni- and multivariate Cox regression analysis were performed to assess the survival rate in relevant patients. Results: A total of 210 IPAH patients at the mean age of (32±10) years were finished cardiopulmonary exercise test (CPET) and received regular follow-up study including 159 female. There were 31 patients died and 1 received lung transplantation over 41 months follow-up period. OUES was positively related to peak oxygen uptake (VO2)/body weight (r=0.71, P<0.0001). Multivariate analysis demonstrated that OUESI and NT-proBNP could independently predict the prognosis of IPAH patients. The 5-year survival rate in patients with OUESI≤0.52 L/(min?m2) was lower than those with OUESI>0.52 L/(min?m2) (41.9% vs 89.8%), P<0.0001.Conclusion: OUES as a submaximal CPET parameter may well predict the prognosis in IPAH patients.

Objective To explore the effects of Living with Hope Program(LWHP) on family caregivers of patients with advanced lung cancer.Methods Totally 60 family caregivers of patients with advanced lung cancer were randomly divided into the experimental group and the control group.The experimental group received LWHP intervention and routine care knowledge education,the control group only received routine care knowledge education.Hope,self-efficacy,anxiety and depression,and quality of life were evaluated at the first week,the second week,the first month,and the third month.Differences between two groups were compared using variance analysis of repeated measurements.Results The self-evaluation of the intervention was 76.6％,and the main effects of hope level,selfefficacy,anxiety and depression,and mental health were statistically significant (P＜0.05);the time effect on hope level and self-efficacy were statistically significant (P＜0.05);there were interaction effects between intervention and time on hope level,self-efficacy,anxiety and depression,and mental health (P＜0.05).Conclusion LWHP can effectively improve hope level,self-efficacy and mental health status,and alleviate anxiety and depression of family caregivers of patients with advanced lung cancer.
