ABSTRACT
OBJECTIVES@#Age-related macular degeneration (AMD) is one of the 3 major eye diseases recognized by WHO to prevent blindness, and which is the main cause of irreversible visual impairment in the elderly. This study aims to analyze the disease epidemiological burden, and provide a theoretical foundation for the prevention and control of AMD in China based on the data in global burden of disease (GBD) 2019.@*METHODS@#The prevalent cases/prevalence, disability-adjusted life year (DALYs)/DALY rate of AMD and socio-demographic index (SDI) for global and China were searched from the GBD 2019 database to analyze the epidemiological trend, age-period-gender trend of AMD in China from 1990 to 2019, and to evaluate the relations between the prevalence and SDI.@*RESULTS@#In 2019, the prevalence of AMD in China was at a high level in the world, and the number of prevalent cases were 1.93 times of that in 1990. The prevalence and DALY rates continued to rise. The age trend of AMD in China was high at the middle of the age stages and low at the two ends, and which was higher in the female than in the male. With the increase of SDI, the prevalence of AMD was increased linearly.@*CONCLUSIONS@#The disease burden of AMD in China is increased significantly and is positively correlated with the social development from 1990 to 2019. It is of great significance to study the relationship between epidemilolgical data of AMD and social development level for diagnosis treatment and policy of AMD.

Objective@#To analyze the correlation between parental involvement and the formation of good eye use behavior in children,and to provide theoretical basis for more accurate prevention and control of myopia.@*Methods@#A total of 2 726 children and their parents from 3 primary schools were selected from April to May 2021 by clustering sampling method. Children s ocular parameters, eye use behavior, general characteristics of parents, and parental involvement were collected through ocular measurements and questionnaires, respectively.@*Results@#Parental involvement was associated with family economic, parental education level, and parental myopic status( P <0.05). Children s myopia risk was associated with parental involvement: lower myopia risk was associated with frequent parental involvement in behavioral management of child sleep and child outdoor activities( P <0.01). Parents who always/frequently participate in the management of children s eye behavior have an average daily screen time of <2 h ( OR= 1.95 , 95%CI =1.31-2.90), and daily outdoor activity time>2 h ( OR=0.78, 95%CI =0.65-0.93), daily sleep time >8 h ( OR= 0.52 , 95%CI =0.40-0.68), daily continuous reading and writing time <1 h ( OR=1.33, 95%CI =1.30-1.56), reading and writing The distance from the desktop > 30 cm ( OR=0.57, 95%CI =0.34-0.95) had a statistically significant effect ( P <0.05).@*Conclusion@#High parental involvement may help school age children develop good eye habits and reduce the risk of childhood myopia. Parental involvement is higher among those who had myopia themselves, and parental involvement is positively associated with total household income and parental literacy.
ABSTRACT
Objective:To evaluate the ability of light dispersive colorimetry to detect hemoglobin (Hb) in lipid blood samples and its feasibility as an alternative to plasmapheresis commonly used in the laboratory.Methods:Routine blood samples of 276 inpatients in Fujian Provincial Hospital from July 2020 to July 2021 were collected. Routine blood samples of 276 inpatients were collected. There were 169 males and 107 females, aged from 16 to 97 years. 183 non-lipid blood samples and 93 lipid blood samples were collected.(1) One case each of low, medium and high Hb value in non-lipid blood and lipid blood samples were collected, and the precision and the linearity of light scattering method was detected.(2)Non-lipid blood samples divided into Hb low-value group, median-value group and high-value group, which were measured by light scattering method and colorimetric method to compare Hb values. (3)Non-lipid blood samples were divided into Hb low-value group, median-value group and high-value group. Plasma exchange was carried out with different concentrations of fat emulsion. The bias and linearity of Hbc2 and Hbc1, Hbo2 and Hbc1 were analyzed by MedCalc19.1 software. The Hbc2 and Hbc1 bias ( CV%) and Hbo2 and Hbc1 bias ( CV%) were calculated. T test was used to analyze the influence of different concentrations of triglyceride on Hb bias.(4)Blood samples were divided into Hb low-value group, median-group and high-value group. The Hb of light scattering method was compared with the colorimetric method after plasma exchange. Results:(1)The intrabatch precision of light scattering method for non-lipid blood and lipid blood specimens was within the allowable range ( CV<1.5%), and the good linearity ( R2=1.000).(2)The bias of Hb measured by light scattering method and colorimetric method in the three groups was below 3.5%(-0.58±2.34,0.16±1.52,1.15±1.56), within the allowable total error range. The two methods have the equivalence and good linear relationship ( r=0.999).(3)The concentrations of Hbo2 in the low (except 4.1 mmol/L), medium and high Hbo2 groups were equivalent to those in the non-lipid blood colorimetry (Hbc1), and the two methods were well correlated. The results of light scattering method have nothing to do with the concentration of lipid blood.(4)There was no significant difference of the Hb between the light scattering method and plasma exchange method in three groups ( P>0.05), Both of them have equivalence and good correlation ( R2=0.968,0.948,0.870). Conclusion:Light scattering method can effectively reduce the effect of lipid blood on hemoglobin determination, and can replace the traditional plasma exchange method, which has high clinical application value.

The existing problems in current research and application were noted, and some suggestions for further research were put forward.
ABSTRACT
Objective To explore the influence of cognitive-behavioral intervention on the anxiety and oral health-related quality of life in adult orthodontic patients.Methods 152 adult orthodontic patients whose MDAS scores were greater than 11 were divided into the intervention group and the control group according Multistage Grouping Process.The former were treated with MBT appliance combined with cognitive-behavioral intervention,and the latter were treated with MBT appliance only.The State-Trait Anxiety Inventory(STAI) was adopted to evaluate anxiety in all patients during orthodontic treatment,and the UK oral health-related quality of life questionnaire(OHRQoL-UK) was adopted to evaluate the oral health-related quality of life in all patients before and after orthodontic treatment,respectively.Results 1.After 3 and 6 months cognitive-behavioral intervention,the scores of SAI in the intervention group(50.37±9.18,35.65±8.92) were significantly reduced compared to the control group(56.62± 10.52,54.13± 10.03) (P＜0.01).After 6 months cognitive-behavioral intervention,the scores of TAI in the intervention group(47.92±6.82) were significantly reduced compared to the control group(51.52±7.41) (P ＜0.05).2.After the orthodontic treatment,the scores of OHRQoL-UK in the intervention group(58.27±13.43) were significantly improved compared to the control group (51.99± 11.69) (P＜ 0.01).3.The oral health-related quality of life after the orthodontic treatment were significantly related to post-treatment anxiety of adult orthodontic patients(r=-0.192 ～-0.459,P＜ 0.05).Conclusion Cognitive-behavioral intervention can effectively reduce anxiety and improve the oral health-related life quality in the adult orthodontic patients.
ABSTRACT
Objective To investigate the role of the expression of latent transforming growth factor beta binding protein-1 (LTBP-1) and transforming growth factor beta receptor type Ⅱ(TGF-beta R Ⅱ) in the pathogenesis of condyloma acuminatum (CA). Methods Samples were resected from the lesions of 30 patients with CA and prepuces of 17 normal human controls. The mRNA and protein expressions of LTBP-1 and TGF-betaR Ⅱ were assessed by quantitative real-time PCR and a streptavidin-biotin-peroxidase staining technique, respectively. Results As shown by Real time PCR, the mRNA expression levels of LTBP-1 and TGF-betaR Ⅱ were significantly higher in CA tissues than those in the controls, with the average value of 2 (-Delta Delta α) being 2.46 and 3.43, respectively. A lower intensity of stainning was observed for LTBP-1 and TGF-betaR Ⅱ in CA tissues compared with the normal controls (182.51±9.89 vs 167.78±12.56, 187.35± 11.23 vs 170.15±13.21, t = 5.62, 3.70 respectively, both P <0.01). Conclusion The decrease in the expres-sion of both LTBP-1 and TGF-betaR Ⅱ may lead to the abnormality in the activation of TGF-beta and signal transduction pathways.
