Objective: To study the impact of sleep characteristics on myopia, among lower primary school students in Shanghai, so as to provide foundation for the prevention of the onset and development of myopia. Methods: A total of 636 students from the first and second grades of two primary schools in Jiading District, Shanghai, were selected through cluster random sampling for questionnaire surveys and ophthalmological examinations in October 2022. The Childrens Sleep Habits Questionnaire (CSHQ) was used to assess sleep quality at baseline. Ophthalmological examinations were conducted in October 2023(479), during which the students study time, screen time and outdoor activity time were monitored for twoweek, repeated twice. Generalized multivariable Logistic regression models and linear regression models were employed to examine the association between sleeprelated factors and myopia, as well as the strength of this association. Results: The baseline survey indicated a myopia prevalence of 18.58%, with 17.18% at followup. The average CSHQ total score was (51.58±4.44), and the average daily sleep duration was (9.43±4.84)h/d, with only 11.6% of participants meeting the recommended sleep sufficiency. Multivariable regression models indicated that insufficient sleep showed positive association with myopia (OR=1.64, 95%CI=1.05-2.56), while bedtime duration was significantly negative associated with myopia (OR=0.74, 95%CI=0.63-0.91, P＜0.05), adjusting for confounding factors. Inconsistency in bed rest time was a risk factor for myopia (OR=1.07, P<0.05), and the consistency of bed rest time, and wakeup time showed statistically significant correlations with SE (P<0.05). There was also statistically significant correlations between consistency in sleep time, bed rest time, and wakeup time with AL (P<0.05). Conclusions Insufficient sleep and bedtime duration are correlated with the onset and progression of myopia. It is critical to ensure sufficient sleep duration and regular sleep habits for children to reduce the occurrence of myopia in the primary school students.

OBJECTIVE To investigate the in vitro anti-inflammatory effects and mechanisms of oblongifolins A （OA） extracted from Garcinia oblongifolia. METHODS RAW264.7 cells were used as the research subject and divided into control group （0.5% DMSO）， lipopolysaccharide （LPS） group （1 μg/mL）， DEX group （10 µmol/L DEX+1 μg/mL LPS）， and low-， medium-， and high-concentration groups of OA （7.5， 15， 30 µmol/L OA+1 μg/mL LPS）. Except for the control group， the remaining groups were first stimulated with LPS for 1 hour and then mixed with drugs for 24 hours. The morphological changes of cells were observed in each group. The contents of nitric oxide （NO）， reactive oxygen species （ROS）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， IL-4 and IL-10 were detected in cells of each group； mRNA expression levels of TNF-α， IL-6 and IL-1β were measured. The expression of key proteins in the nuclear factor κB （NF-κB） and nuclear factor-erythroid 2-related factor 2 （Nrf2） signaling pathways in each group， as well as the nuclear translocation of NF-κB p65 and Nrf2 proteins in control group， LPS group and OA high-concentration group， were detected. RESULTS Compared to the LPS group， the number of spindle-shaped and irregular cells gradually decreased in OA groups， the contents of NO， ROS （except for OA low-concentration group）， TNF-α， IL-6 and IL-1β， the mRNA expressions of TNF-α， IL-6 （except for OA low-concentration group） and IL-1β as well as the protein expressions of phosphorylated NF-κB p65 （p-NF-κB p65）， p-IκBα， and Kelch-like ECH-associated protein 1 （Keap1） were decreased significantly （P＜0.05）. The contents of IL-4 and IL-10， protein expressions of IκBα， Nrf2 （except for OA low- and medium-concentration groups）， HO-1 （except for OA low-concentration group） and NQO1 were all increased significantly （P＜0.05）. OA of high concentration could inhibit NF-κB p65 protein nuclear translocation and promote Nrf2 protein nuclear translocation. CONCLUSIONS OA can suppress LPS-induced inflammation in RAW264.7 macrophages. The underlying molecular mechanism likely entails the inhibition of the NF-κB signaling pathway， the activation of the Nrf2 signaling pathway and the reduction of ROS and inflammatory factor release.

Objective To investigate the protective effect of herba artemisiae scopariae extract on multidrug resistance protein 3(MDR3)gene mutation-induced neonatal parenteral nutrition-associated cholestasis(PNAC)and its possible mechanism.Methods ①Human primary hepatocytes were treated with cell culture in vitro,CRISPR/Cas9 lentivirus infection and MDR3 mutant gene lead-in.The levels of hepatic and biliary biochemical indexes[alanine transaminase(ALT),aspartate transaminase(AST),total bilirubin(TBil),direct bilirubin(DBil),indirect bilirubin(IBil),total bile acid(TBA)]in the supernatant of hepatocytes before and after 16,32,48 hours were compared to determine the time required for fatty acid induction of PNAC hepatocyte model with MDR3 gene mutation.② Human primary hepatocytes were divided into blank control group,MDR3 gene wild type group,MDR3 gene mutation group,and herba artemisiae scopariae extract intervention group according to random number table method.The blank control group was treated with culture medium only,the MDR3 gene wild type group was infected with lentivirus and mixed with wild type MDR3 gene and culture medium,the MDR3 gene mutation group was infected with lentivirus and cultured in culture medium with the mutant genes lead-in of LV-MDR3KI(c.485T>A,c.2793insA,c.1031G>A,c.3347G>A)mutation,while the MDR3 mutant gene was lead-in by lentivirus infection and cultured in culture medium,and then pretreated with 100 g/L herba artemisiae scopariae extract in the herba artemisiae scopariae extract intervention group,then the four groups of hepatocytes were induced with 1%fat emulsion,and the treatment time was the time needed to construct the PNAC hepatocytes model with MDR3 gene mutation.The levels of ALT,AST,TBil,DBil,IBil and TBA in the supernatant of hepatocytes were measured by enzyme-linked immunosorbent assay(ELISA).The mRNA expression abundance of adenosine triphosphate binding cassette proteins(ABCB4,ABCB11,ABCC2,ABCC3,ABCC4)encoding MDR3,bile salt export pump(BSEP),multidrug resistance associated protein(MRP)2-4,and tumor necrosis factor-α(TNF-α)genes were detected by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR).Results Compared to the blank control group and MDR3 gene wild type group,there was no significant difference in the levels of ALT,AST,TBil,DBil,IBil,TBA in the supernatant of MDR3 gene mutant group before and 16 hours after induction with 1%fat emulsion,however after treated with 1%fat emulsion for 32 hours and 48 hours,the levels of ALT,AST,TBil,DBil,IBil,TBA in the supernatant of MDR3 mutant hepatocytes were significantly increased(P<0.05),consequently the time required for fatty acid induction of PNAC hepatocyte model was 32 hours.At 32 hours after treatment with fat emulsion,the levels of ALT,AST,TBil,DBil,TBA in the supernatant of hepatocytes in the herba artemisiae scopariae extract intervention group were significantly decreased[ALT(ng/L):148.3±2.3 vs.164.9±7.0,AST(ng/L):2767.4±78.8 vs.3239.4±107.1,TBil(μmol/L):7.6±0.2 vs.13.6±0.3,DBil(μmol/L):1.8±0.1 vs.5.7±0.2,TBA(μmol/L):3.4±0.2 vs.6.7±0.1,all P<0.05].The ABCB4,ABCC2,ABCC3,ABCC4 mRNA expression of MDR3,MRP2,MRP3,MRP4 in the blank control group,MDR3 wild type group,MDR3 gene mutation group and the herba artemisiae scopariae extract intervention group had no significant difference.The expression of TNF gene mRNA was highly expressed in MDR3 gene mutation group(2-??Ct:1.258±0.200 vs.1.001±0.052),and was low expressed in the herba artemisiae scopariae extract intervention group(2-??Ct:0.387±0.247 vs.1.258±0.200),and there was a significant difference between the two groups(both P<0.05).Compared to the MDR3 gene mutation group,the ABCB11 gene encoding BSEP mRNA expression in the herba artemisiae scopariae extract intervention group was significantly increased(2-??Ct:2.955±0.479 vs.1.333±0.529,P<0.05).Conclusion The herba artemisiae scopariae extract has a protective effect on PNAC induced by MDR3 gene mutation,which may be related to antagonizing inflammatory reaction,decreasing the expression of TNF mRNA and improving the expression of ABCB11 gene encoding BSEP.
