Background With China's socio-economic development, the dietary structure of Chinese residents has gradually shifted from a traditional Eastern pattern characterized by high carbohydrate intake to a relatively high-fat Western dietary model, alongside a growing burden of chronic diseases. However, dietary changes may vary across different occupational groups. Objective To analyze the long-term trends in dietary energy and three major macronutrient intake among various occupational groups aged 18-59 years in nine provinces of China from 1989 to 2018, providing a scientific basis for developing occupation-specific dietary intervention strategies. Methods Based on 11 waves of data (1989–2018) from the China Health and Nutrition Survey (CHNS), 57458 employed individuals aged 18-59 years were selected as observation subjects after applying inclusion and exclusion criteria. Joinpoint regression was used to analyze temporal trends by calculating the annual percentage change (APC) and average annual percentage change (AAPC) with 95% confidence intervals. The analysis covered the energy supply ratio from the three major macronutrients and the proportion of the participants within the acceptable macronutrient distribution ranges (AMDR) for the total occupational population and specific occupational group. Results From 1989 to 2018, the dietary structure of the occupational population in the nine provinces gradually Westernized. The carbohydrate energy supply ratio showed a decreasing trend (AAPC=−0.77%, 95%CI: −1.00%, −0.55%, P<0.05), while the fat energy supply ratio increased (AAPC=1.42%, 95%CI: 1.07%, 1.77%, P<0.05). The protein energy supply ratio remained largely unchanged (AAPC=−0.19%, 95%CI: −0.08%, 0.46%, P>0.05), and the total energy intake declined (AAPC=−0.62%, 95%CI: −0.94%, −0.30%, P<0.05). Among the occupational groups studied, white-collar workers were the first to show characteristics of dietary Westernization. Using the AMDR as the criterion, their average fat energy supply ratio first exceeded the AMDR upper limit (30%) in 1993, and their average carbohydrate energy supply ratio first fell below the AMDR lower limit (50%) in 2006, both time points being earlier than other occupational groups. Agricultural workers lagged in this transition (their average fat energy supply ratio first reached ≥30% in 2011), but their rate of increase in the fat energy supply ratio was the fastest among all occupational groups (AAPC=1.59%, 95%CI: 0.90%, 2.30%, P<0.05; P for trend comparison between groups<0.05). The other three occupational groups (blue-collar workers, service workers, and others) generally fell between these two extremes. Taking the fat energy supply ratio as an example, their AAPCs of increase were 1.02% (95%CI: 0.73%, 1.32%, P<0.05) for blue-collar workers, 0.85% (95%CI: 0.61%, 1.09%, P<0.05) for service workers, and 0.88% (95%CI: 0.58%, 1.17%, P<0.05) for others. Conclusion From 1989 to 2018, the macronutrient structure of the occupational population aged 18-59 years in nine China provinces is gradually Westernized. The energy supply ratios of carbohydrates and proteins primarily face issues of potential inadequacy, while the fat energy supply ratio is excessively high. Furthermore, the patterns of change vary among different occupational groups. It is recommended to propose personalized dietary advice tailored to specific occupations.

AIM: To compare the effects of different nucleus chopping methods on the central corneal thickness, corneal endothelial cell(CEC)count and tear inflammatory indicators in patients with hard nucleus cataract.METHODS: Retrospective study. Totally 89 patients(89 eyes)with hard nucleus cataract who treated in our hospital were included from January 2020 to December 2022. According to different intraoperative nucleus chopping methods, the patients were divided into reverse prechop group(46 eyes)and phaco-chop group(43 eyes). The total effective rate of surgery and visual acuity recovery were compared between the two groups. Corneal related indicators(central corneal thickness, CEC count, CEC area), tear inflammatory indicators and tear film function [tear film break-up time(BUT), Chinese Dry Eye Questionnaire(CDEQ), Schirmer Ⅰ test(SⅠt)] were observed before and after surgery in both groups, and the degree of corneal edema was evaluated.RESULTS: The effective phaco time, phaco energy and cumulative complex energy parameters in the phaco-chop group were longer or higher than those in the reverse prechop group(P<0.05). The macular retinal thickness in the reverse prechop group at 7 d and 1 mo after surgery was thinner than that in the phaco-chop group, the central corneal thickness at 3 and 7 d after surgery was also thinner than that in the phaco-chop group, the CEC count at 3 mo after surgery was more than that in the phaco-chop group, the CEC loss rate was lower than that in the phaco-chop group, and the CEC area at 3 mo after surgery was smaller than that in the phaco-chop group(P<0.05). The levels of tear TNF-α and IL-6 at 7 d and 1 mo after surgery in the reverse prechop group were lower than those in the phaco-chop group(P<0.05). The BUT at 1 and 3 mo after surgery was longer in the reverse prechop group than that in the phaco-chop group(P<0.05). The CDEQ score in the reverse prechop group was lower than that in the phaco-chop group at 1 and 3 mo after surgery(P<0.05). The SⅠt at 1 and 3 mo after surgery was higher in the reverse prechop group compared with that in the phaco-chop group(P<0.05). The degree of corneal edema at 1 d after surgery was milder in the reverse prechop group than that in the phaco-chop group(P<0.05). CONCLUSION: Compared with phaco-chop, the application of reverse-chopper prechop combined with phacoemulsification can better reduce the ultrasonic energy in the treatment of hard nuclear cataract, and it is more conducive to reducing the postoperative inflammatory degree, improving the tear film function and relieving the corneal edema degree.

Objective:To explore the mechanism of Coicis Semen in treating non -small cell lung cancer combined with network pharmacology and in vitro cell experiment.Methods:The components and potential targets of Coicis Semen were obtained from TCMSP, and NSCLC related targets were collected from Genecards and Drugbank. They were intersected to get common targets. An intersection target PPI network was constructed using STRING database. GO function and KEGG pathway enrichment analysis were performed using DAVID database. A "disease-drug component-target" network was constructed using Cytoscape 3.8.0. The CCK-8 method was used to screen the concentration of Coicis Semen, and the cells were randomly divided into control group, Coicis Semen low-concentration group (0.125 mg/ml), Coicis Semen high-concentration group (0.25 mg/ml), Coicis Semen low concentration+FoxO1 inhibitor group, and FoxO1 inhibitor group (50 μmol/L) using a random number table. Cell proliferation ability was determined using CCK-8 method, and cell migration and invasion ability were detected using cell scratch assay and Transwell cell invasion assay. Western blot was used to detect the expression of FoxO1, cofilin-1, and p-cofilin-1 proteins.Results:A total of 9 active components and 246 targets were screened from Coicis Semen, 1 074 targets related to non-small cell lung cancer, and 11 intersecting targets were identified. The key targets of Coicis Semen in the treatment of non-small cell lung cancer were MAPK1, MAPK8, MAPK14, CDK2, INSR, AR, FGFR2, PGR, DHFR, and PLAU; GO functional enrichment analysis showed that Coicis Semen had an impact on the cellular, molecular, and biological functions of A549 cells; KEGG pathway enrichment analysis showed that the pathways of Coicis Semen in treating non-small cell lung cancer mainly focus on FoxO pathway, MAPK pathway, prostate cancer pathway, Ras pathway, etc. Compared with the control group, the proliferation rate, migration rate, and invasion number of A549 cells in the low and high concentration groups of Coicis Semen decreased ( P<0.05), p-cofilin-1 expression decreased ( P<0.05), and FoxO1 expression increased ( P<0.05). Conclusion:Coicis Semen can treat non-small cell lung cancer by regulating MAPK1, MAPK8, and MAPK14 targets, and acting on pathways such as the FoxO and MAPK pathways.

Bone formation and deposition are initiated by sensory nerve infiltration in adaptive bone remodeling. Here, we focused on the role of Semaphorin 3A (Sema3A), expressed by sensory nerves, in mechanical loads-induced bone formation and nerve withdrawal using orthodontic tooth movement (OTM) model. Firstly, bone formation was activated after the 3rd day of OTM, coinciding with a decrease in sensory nerves and an increase in pain threshold. Sema3A, rather than nerve growth factor (NGF), highly expressed in both trigeminal ganglion and the axons of periodontal ligament following the 3rd day of OTM. Moreover, in vitro mechanical loads upregulated Sema3A in neurons instead of in human periodontal ligament cells (hPDLCs) within 24 hours. Furthermore, exogenous Sema3A restored the suppressed alveolar bone formation and the osteogenic differentiation of hPDLCs induced by mechanical overload. Mechanistically, Sema3A prevented overstretching of F-actin induced by mechanical overload through ROCK2 pathway, maintaining mitochondrial dynamics as mitochondrial fusion. Therefore, Sema3A exhibits dual therapeutic effects in mechanical loads-induced bone formation, both as a pain-sensitive analgesic and a positive regulator for bone formation.
