Phacoemulsification with intraocular lens implantation(Phaco+lOL)has become the main treatment for cataracts due to small incision and fast recovery. Phacoemulsification can damage the conjunctiva, cornea and other ocular surface tissues, causing local inflammation, which in turn leads to eye dryness and discomfort after surgery. According to studies, patients who suffer from phacoemulsification most experience dry eye syndrome within 24 h, which gradually worsens and reaches its peak in the following 1 wk, seriously affecting their quality of life. The review aims to comprehensively investigate the effects of preoperative patient physical conditions and local ocular status, intraoperative maneuvers and postoperative treatments on postoperative dry eye, with the expectation of formulating scientific and effective preventive measures for potential dry eye patients after phacoemulsification, and providing a theoretical basis for postoperative dry eye treatment.

Cleft lip and palate (CLP) are common congenital craniofacial developmental disorders with a high incidence rate among newborns. Due to the influence of the cleft, an increased frequency of anomalies occurs in cleft-adjacent teeth. This review summarizes the abnormality of tooth development and malposition characteristics of the central incisors, lateral incisors, and canines adjacent to the alveolar cleft in CLP patients and treatment progress in order to provide information for related clinical treatment and research. The literature reveals that central incisors, lateral incisors, and canines adjacent to the alveolar cleft exhibit various types and degrees of abnormalities. The alveolar cleft-adjacent central incisors show significantly smaller mesiodistal diameters, root lengths, and root volumes compared to the non-alveolar cleft side, while the crown-to-root ratio is larger. Further, they are inclined distally and lingually compared to the non-alveolar cleft side. The alveolar cleft-adjacent lateral incisor is the most common missing or impacted tooth and is often affected by microdontia. The total length and root length of the alveolar cleft-adjacent canines are significantly smaller, while the crown-to-root ratio is larger on the alveolar cleft side. In addition, they are inclined mesially and buccally compared to the non-alveolar cleft side. Further, they are higher positioned and located closer to the midline. For developmental anomalies, impacted central incisors can be addressed by orthodontic space preparation to facilitate eruption or surgical crown exposure and orthodontic traction. Treatment of missing lateral incisors can involve orthodontic closure of the gap or preservation of the space for subsequent prosthetic restoration. When lateral incisors present with developmental defects, such as microdontia, peg-shaped teeth, or invaginated teeth, a comprehensive decision is necessary to determine whether to retain and restore or extract the malformed lateral incisors. Treatment of impacted canines after bone grafting involves either extraction or traction to facilitate the eruption of the impacted tooth. For malposition, presurgical orthodontic treatment can correct teeth with excessive inclination or rotation on the cleft side to improve the effectiveness of bone grafting surgery. Postsurgical orthodontic treatment can enhance the stability of bone grafting surgery. Although numerous studies have explored the dental characteristics of patients with CLP, the lack of applicability and specificity still need to be elucidated, thus indicating the need for further research.

ObjectiveTo analyze the exposure-response relationship of peripheral whole blood chromium level and lung function as well as genetic toxicity indicators in workers exposed to hexavalent chromium [Cr(Ⅵ)] compounds, and to propose a biological exposure limit of whole blood chromium for soluble Cr(Ⅵ) compounds-exposed workers. Methods A total of 515 workers from a dynamic occupational Cr(Ⅵ) compounds-exposed cohort in an enterprise from 2010 to 2017 were selected as the research subjects using a retrospective cohort study. A total of 918 followed-up results of research subjects and baseline data of a cohort were analyzed based on bibliometric analysis. The results include lung function tests, whole blood chromium level detected by inductively coupled plasma-mass spectrometry, urinary 8-hydroxy-2′-deoxyguanosine (8-OHdG) detected by high performance liquid chromatography-tandem mass spectrometry, peripheral micronuclei frequency (MNF) detected by cytokinesis-block micronucleus assay, and mitochondrial DNA copy number (mtCN) detected by real-time fluorescence quantitative polymerase chain reaction. Results The results of bibliometric analysis showed that domestic and foreign studies on biological monitoring of Cr(Ⅵ) compounds increased year by year in the past 30 years, and whole blood chromium levels had a good correlation with the occupational Cr(Ⅵ) compounds exposure. The geometric mean of whole blood chromium levels in males and females among the occupational Cr(Ⅵ) compounds exposure cohort was 2.77 and 1.79 μg/L, respectively. A turning point appeared in 6.00 μg/L chromium in whole blood of the exposure-response curve of whole blood chromium levels with lung function indicators and genetic toxicity indicators. For each unit increase in the natural logarithm-transformed whole blood chromium level, the forced expiratory volume in one second (FEV₁) decreased by 0.05 L, the FEV₁/forced-vital-capacity decreased by 0.67%, the peak expiratory flow decreased by 0.15 L/s, the maximal mid-expiratory flow decreased by 0.09 L/s, the MNF increased by 0.149‰, the urinary 8-OHdG increased by 0.090 μg/g, and the mtCN increased by 0.013. When the whole blood chromium level was >6.00 μg/L, there was a significant increase in urinary 8-OHdG, MNF, and mtCN (all P<0.01). Conclusion The level of whole blood chromium can be used as a biomarker for occupational exposure to soluble Cr(Ⅵ) compounds. The preliminary biological exposure limit is set at 6.00 μg/L for whole blood chromium in workers exposed to soluble Cr(Ⅵ) compounds.

Preschool age(3-6 years old)is a critical period for visual development, and it is crucial to detect and treat visual problems in preschool children as early as possible. Visual acuity charts are important tools for screening visual issues in children. In China, the commonly used charts are the standard logarithmic visual acuity chart and the pediatric optotype chart, while overseas, the Lea, HOTV, and ETDRS visual acuity charts are frequently employed. Numerous studies have reported the measurability, repeatability, and sensitivity of these three charts in diagnosing visual-related problems in children. However, the application of these three charts is relatively limited in China. This article provides a comprehensive review of the design principles, clinical applications, and characteristics of these three visual acuity charts, so as to better understand their applicability and limitations in preschool children, and provide reference for the selection and improvement of vision examination methods in the future.

Objective This article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study,a systematic review,and a meta-analysis.Methods The study was conducted in three stages.In the first stage,subjects were recruited for health examination in four hospitals in Chengdu,Tianjin,Beijing,and Chongqing,China,from 2015 to 2020,and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center.In the second stage,Embase,PubMed,Wanfang Data,VIP,and CNKI databases were searched for related studies published up to May 2021,and a meta-analysis was conducted to further verify such association.In the third stage,the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature.Results A total of 633 948 participants were enrolled in the cross-sectional study,and the prevalence rate of GSD was 7.844%.The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD(P＜0.05).Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes,ages,and subtypes of GSD.A total of 80 articles were included in the systematic review and the meta-analysis,and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure.Conclusion Hypertension significantly increases the risk of GSD,and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

Objective The aim of this study was to establish an acute gastric mucosal injury(AGMI)rat model induced by hydrochloric acid(HCl)at different concentration gradients and to investigate the effects of intravenous injection of evans blue(EB)at various concentrations and dosages on survival rate and superficial extravasation.Methods(1)Wistar rats were randomly assigned to five weight-based groups:150～180 g,180～200 g,200～250 g,300～400 g,400～500 g.Each group was further subdivided into eight subgroups based on HCl concentration,specifically:0.40,0.45,0.50,0.55,0.60,0.65,0.70 mol/L HCl,along with a control group treated with saline.This result ed in a total of 40 subgroups,with three rats per subgroup,summing up to 120 animals in total.The survival rate of rats 24 hours post-modeling was assessed,and the interaction between body weight and HCl concentration on rat survival was analyzed.Following the establishment of five graded HCl concentrations,gastric mucosal pathological changes were observed microscopically using hematoxylin-eosin staining(HE)staining.(2)From these result,the highest suitable concentration of HCl was selected to prepare the AGMI model.Subsequently,rats were randomly allocated into different groups based on the concentration and dose of EB,specifically:EB 1(0.5％,0.4 mL),EB 2(1％,0.1 mL/100 g),EB 3(1％,0.2 mL/100 g),EB 4(2％,0.1 mL/100 g),EB 5(2％,0.2 mL/100 g),and EB 6(5％,0.1 mL).Each group consisted of five rats,totaling 30 animals.The survival rate and extent of dermal exudation were evaluated 24 hours post-injection of EB.Results(1)Post-modeling symptoms in AGMI rats intensified with increasing concentrations of HCl,with the 24-hour survival rate in all weight groups being 0％for both 0.65 mol/L and 0.70 mol/L HCl.Kaplan-Meier survival curves indicated significant differences in survival rates among rats in different HCl concentration groups(P＜0.001).Furthermore,a significant interaction effect between HCl concentration and body weight on rat survival time was observed(P＜0.001).The five gradient HCl concentrations established were from 0.40、0.45、0.50、0.55、0.60 mol/L.Histological observations revealed that the degree of inflammatory cell infiltration in the gastric mucosa of AGMI rats escalated with increasing HCl concentrations.(2)AGMI rats prepared with 0.60 mol/L HCl and injected with 5％EB(0.1 mL)had a 24 h survival rate of only 40％.Kaplan-Meier survival curves showed no significant differences in survival rates among AGMI rats under different concentrations and dosages of EB(P＞0.05).Analysis of superficial extravasation revealed that skin and eye color were lighter in EB 1 group rats,with fewer extravasation points,while rats in EB 4 and EB 5 groups exhibited more apparent skin color changes and extravasation.One-way ANOVA further confirmed that the number of superficial EB extravasation points in the EB 3,EB 4,and EB 5 groups was significantly higher than that in EB 1 group(P＜0.05,P＜0.01).Conclusions HCl modeling successfully achieved a setting of multiple precise concentration gradients.Gastric lavage with HCl concentrations ranging from 0.40 mol/L to 0.60 mol/L in rats with a fasting body weight of 180～200 g was used to successfully prepare an AGMI model.Intravenous injection of 2％EB(0.2 mL/100 g)can facilitate the study and analysis of the distribution characteristics of superficial EB extravasation points in AGMI rats over time and as the condition progresses.

Objective:To compare the aortic remodeling of the Fabulous stent system and standard thoracic aortic endovascular repair (TEVAR) on distal aorta type B aortic dissection (TBAD). Methods:The prospective data collected between Dec 2017 and Oct 2019 from 134 patients with type B aortic dissection (TBAD) who underwent treatment with the "Fabulous" stent system, and retrospective data from 159 TBAD patients receiving standard TEVAR from corresponding multicenter. By using propensity score matching analysis, we compared the prognosis and aortic remodeling outcomes in patients undergoing Fabulous and standard TEVAR treatments during a 1-year postoperative follow-up.Results:In this study, 62 patients in Fabulous group and 62 patients in standard TEVAR were included.There were no significant statistical differences in baseline characteristics between the two groups. In terms of aortic remodeling in bare stent region, Fabulous group had better change trends of diameter of true lumen [10.6 (4.4, 14.5) mm vs. 4.7 (0.9, 10.7) mm, P=0.001] and false lumen [-24.2 (-30.5, -4.9) mm vs. 0.7 (-11.8, 2.3) mm, P<0.001] than those in the standard TEVAR group. The rate of complete false lumen thrombosis was also higher in the Fabulous group (62.9% vs. 37.1%, P=0.042). Conclusion:The Fabulous stent system, when compared to standard TEVAR surgery, demonstrates good aortic remodeling outcomes in the distal aorta.
