Objective:To analyze the relationship among thyroid autoimmunity (TAI), thyroid function, and gestational diabetes mellitus (GDM) in early pregnant women in Xi'an.Methods:A prospective study included pregnant women who underwent prenatal check-ups at the Northwest Women's and Children's Hospital from November 2020 to October 2021, with a gestational age of 6 to 14 weeks. Thyroid function, thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb), and urinary iodine levels were measured, and the prevalence of thyroid disease and GDM was monitored. The subjects were divided into four groups: TPOAb positive only, TgAb positive only, both TPOAb and TgAb positive, and both TPOAb and TgAb negative, to compare the differences in the prevalence of thyroid disease and GDM among the groups. Statistical analysis was performed using Kruskal-Wallis rank-sum test, Bonferroni correction, Chi-square test, and a multivariate logistic regression model was used to analyze the relationship between TAI, thyroid disease, and GDM. Results:A total of 20 243 early pregnant women were included in this study, among which 1 615 (7.98%) were positive for TPOAb only; 865 (4.27%) were positive for TgAb only; 1 672 (8.26%) were positive for both TPOAb and TgAb (both positive group); and 16 091 (79.49%) were negative for both TPOAb and TgAb (both negative group). The thyroid stimulating hormone levels in the TPOAb positive only group, TgAb positive only group, and both positive group were significantly higher than those in the both negative group, respectively (Bonferroni correction, all P<0.05); the free thyroxine level in the TPOAb positive only group was significantly lower than that in the both negative group ( P<0.05). After adjusting for age, pre-pregnancy body mass index, and urinary iodine levels, multivariate logistic regression analysis showed that compared to the both negative group, the risk of developing hypothyroidism during pregnancy was significantly increased in the both positive group ( OR=11.49, 95% CI: 2.84-46.39); the risk of developing subclinical hypothyroidism during pregnancy was significantly increased in the TgAb positive only group ( OR=1.99, 95% CI: 1.05-3.76) and the both positive group ( OR=3.74, 95% CI: 2.49-5.63); the risk of developing GDM was significantly increased in the TgAb positive only group ( OR=1.43, 95% CI: 1.04-1.96) and the both positive group ( OR=1.94, 95% CI: 1.53-2.46). Among early pregnant women with normal thyroid function, after adjusting for age, pre-pregnancy body mass index, and urinary iodine levels, multivariate logistic regression analysis showed that compared to the both negative group, the risk of developing GDM was significantly increased in the TgAb positive only group ( OR=1.46, 95% CI: 1.06-2.02) and the both positive group ( OR=1.80, 95% CI: 1.40-2.32). Conclusion:TgAb positive only is a risk factor for subclinical hypothyroidism and GDM. Screening for thyroid autoantibodies, especially TgAb, during pregnancy helps in the early identification of high-risk pregnant women for thyroid dysfunction and GDM.

AIM:To investigate the visual quality and stereopsis after the implantation of PanOptix trifocal intraocular lens(TFNT00).METHODS: A prospective clinical study was conducted. A total of 36 cataract patients(50 eyes)who underwent phacoemulsification combined with TFNT00 implantation in Jinan Mingshui Eye Hospital from November 2022 to April 2024 were selected. They were followed up until 3 mo after the operation. The uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA), uncorrected near visual acuity(UCNVA), objective scatter index(OSI), modulation transfer function cut off(MTF-cut-off), Strehl ratio(SR)and 100%, 20%, 9% contrast visual acuity(CVA)were observed. The binoptometer was used to collect the patients' far and near stereopsis acuities. The defocus curve was drawn after the operation; the Chinese version of the VF-14 Visual Function Index Scale was used to evaluate the visual quality and satisfaction after the operation.RESULTS: There were statistically significant differences in the UCDVA, UCIVA and UCNVA of the patients at different time after the operation(all P<0.05). The transition of the defocus curve was gentle between +0.5--3.0 D after the operation. The OSI value at 3 mo postoperatively after the operation was significantly lower than that before the operation(P<0.01), and the MTF-cut-off, SR, 100% CVA, 20% CVA and 9% CVA were significantly improved than those before operation(all P<0.01). The far and near stereopsis acuities of 34 patients were abnormal before the operation. The far stereopsis acuities of the patients who underwent bilateral eye surgeries were all normal after the operation, and the near stereopsis acuity of 12 patients was normal. Among the patients who underwent unilateral eye surgeries, the far stereopsis acuities of 13 patients were normal, and the near stereopsis acuities of 11 patients were normal. The far and near stereopsis acuities of the patients who underwent bilateral eye surgeries were significantly better than those patients who underwent unilateral eye surgeries.CONCLUSION: The PanOptix trifocal intraocular lens can provide patients with good full-range visual acuity. The stereopsis of the patients with bilateral implants is better than that of the patients with unilateral implants. The overall visual quality and satisfaction of the patients after the operation are relatively high.

Objective: To investigate the situation and influencing factors of school bullying experienced by primary and middle school students, so as to provide the basis for formulating school bullying intervention measures and promoting students' physical and mental health development. Methods: All the counties (cities, districts) in Zhejiang Province were stratified to urban and suburban areas, primary, junior high and senior high school students were selected using a stratified cluster sampling method. Basic information, lifestyle and school bullying were collected through questionnaire surveys. Factors affecting school bullying experienced by primary and middle school students were analyzed using a multivariable logistic regression model. Results: Totally 137 846 valid questionnaires were recovered, with an effective recovery rate of 97.17%. There were 72 526 males (52.61%) and 65 320 females (47.39%). There were 47 561 primary school students (34.50%), 47 701 junior high school students (34.61%) and 42 584 senior high school students (30.89%). A total of 3 987 students suffered from school bullying, accounting for 2.89%. The proportions of being maliciously teased, being intentionally excluded from group activities/isolated, being teased about physical defects or appearance, being hit/kicked/pushed/shoved/locked in a room, being threatened, and being extorted for money were 2.04%, 1.18%, 1.11%, 0.86%, 0.84% and 0.83%, respectively. Multivariable logistic regression analysis showed that the students who were males (OR=1.122, 95%CI: 1.048-1.202), lived in suburban areas (OR=1.322, 95%CI: 1.233-1.418), lived in areas with medium (OR=1.086, 95%CI: 1.006-1.173) or underdeveloped (OR=1.298, 95%CI: 1.191-1.415) economic level, had higher academic levels (junior high school, OR=1.380, 95%CI: 1.270-1.499; senior high school, OR=1.210, 95%CI: 1.083-1.351), lived on campus (OR=1.489, 95%CI: 1.372-1.616), engaged in fights (OR=6.029, 95%CI: 5.585-6.509), attempted to smoke (OR=1.320, 95%CI: 1.128-1.545), drank (OR=1.735, 95%CI: 1.575-1.912), were scolded and beaten by parents (OR=1.972, 95%CI: 1.822-2.135) and were obese (OR=1.240, 95%CI: 1.132-1.360) were more likely to experience school bullying. Conclusion The harm of school bullying to the physical and mental health of primary and middle school students should be taken seriously, and active policy measures should be adopted to strengthen intervention.

Objective:To investigate the effects of ginsenoside Compound K (CK) on proliferation, apoptosis, and autophagy in gastric cancer cells, and to further explore whether it exerts its effects by regulating the AMPK/mTOR signaling pathway.Methods:Human gastric cancer AGS cells were cultured in vitro to the logarithmic growth phase and randomly divided into control group (treated with 0.9% sodium chloride solution), ginsenoside CK group (treated with 50 μM CK) and ginsenoside CK+ Dorsomorphin group (treated with 50 μM CK combined with 10 μM Dorsomorphin). AGS cells were treated with ginsenoside CK at concentrations of 0, 5, 10, 20, 50, 100, and 200 μM, and cell viability was measured by the CCK-8 assay to determine the optimal concentration (50 μM). After treatment according to the above groups, cell viability was assessed by the CCK-8 assay; colony formation was evaluated by the plate clone formation assay; apoptosis was detected by the Tunel assay; autophagy was assessed by MDC fluorescence staining; and the expression levels and phosphorylation status of autophagy-related proteins (Beclin-1, LC3-Ⅱ), apoptosis-related proteins (Caspase-3, Bax, Bcl-2), and AMPK/mTOR signaling pathway-related proteins were analyzed by Western Blot. Statistical analysis of the data was performed using GraphPad Prism 9.1.2 software.Results:Compared with the control group, the apoptosis rate, autophagy degree and the expression levels of Beclin-1, LC3-Ⅱ, caspase-3, Bax and p-AMPK proteins were significantly increased in the ginsenoside CK group ( P<0.05), while the cell viability, clone formation rate, and the expression levels of Bcl-2 and p-mTOR proteins were decreased ( P<0.05). After the addition of AMPK pathway inhibitor Dorsomorphin based on 50 μM ginsenoside CK treatment, the apoptosis rate, the degree of autophagy, and the expression levels of Beclin-1, LC3-Ⅱ caspase-3, Bax, and p-AMPK proteins showed a decreasing tendency ( P<0.05). In contrast, the cell viability, the clone formation rate, and the expression levels of Bcl-2 and p -mTOR protein expression levels showed a certain rebound trend ( P<0.05). The anti-tumor effect of ginsenoside CK was reversed by the combined intervention of ginsenoside CK and dorsomorphin in AGS cells. Conclusion:Ginsenoside CK suppresses gastric cancer cell proliferation while enhancing apoptosis and autophagy through modulation of the AMPK/mTOR signaling pathway, offering a promising novel approach for gastric cancer therapy.

Objective To explore the correlation between the ratio of free triiodothyronine/free thyroxine(FT3/FT4)and the early-phase insulin secretion index(ΔI30/ΔG30)in type 2 diabetes mellitus(T2DM)patients with normal thyroid function.Methods 200 patients with T2DM with normal thyroid function in Hebei General Hospital from September 2019 to June 2021 were selected and divided into the Q1 group with FT3/FT4≤0.26(n=67),the Q2 group with 0.27≤FT3/FT4≤0.29(n=67),and the Q3 group with FT3/FT4≥0.30(n=66)according to the tertiles of the FT3/FT4.The general data,biochemical indicators and islet functions of the three groups were compared,and the relationship between the FT3/FT4 ratio and the ΔI30/ΔG30 as well as the islet β cell function was analyzed.Results The fasting insulin(FIns),2 h postprandial insulin(2 hIns),homeostatic model assessment of islet β cell(HOMA-β)and area under the curve of insulin(AUCI)in Q3 group were higher than those in Q1 and Q2 groups(P<0.05),2 h postprandial blood glucose(2 hPG)in Q3 group was lower than those in Q1 and Q2 groups(P<0.05).Systolic blood pressure in Q2 group was higher than those in Q1 group(P<0.05).Compared with Q1 group,diastolic blood pressure,body mass index(BMI),alanine aminotransferase(ALT),fasting C-peptide(FC-P),area under curve of C-P(AUCC),2 h postprandial C-peptide(2 hC-P)and ΔI30/ΔG30 in Q3 group were significantly higher(P<0.05),and HbA1c was significantly lower(P<0.05).Spearman correlation analysis showed that Δ I30/Δ G30,HOMA-β,AUCI,AUCC and HOMA-IR were positively correlated with BMI,ALT,FC-P,2 hC-P,FIns,2 hIns and FT3/FT4(P<0.05),it was negatively correlated with HbA1c and 2 hPG(P<0.05).Linear regression analysis showed that ΔI30/ΔG30,HOMA-β,AUCI and AUCC were the influencing factors of FT3/FT4 after adjusting for confounding factors.Conclusions ΔI30/ΔG30,HOMA-β,AUCI and AUCC are the influencing factors of FT3/FT4 in T2DM patients with normal thyroid function,suggesting that FT3/FT4 is higher in patients with better islet β cell secretion function.

Objective:To analyze the multimorbidity trends and influencing factors of internet addiction and depressive symptoms among middle school students in Zhejiang Province.Methods:From 2018 to 2023, a multistage stratified random cluster sampling method was used to select middle school students aged 12 to 18 in Zhejiang Province. Internet addiction and depression status were measured by the Internet Addiction Scale and the Center for Epidemiologic Studies Depression Scale. When both symptoms were present, it was defined as multimorbidity.The multivariate logistic regression model was used to analyze the influencing factors of multimorbidity among middle school students, and a trend Chi-square test was used to analyze the changing trends of internet addiction, depression and multimorbidity prevalence. Results:A total of 193 505 students were included in the study. From 2018 to 2023, the prevalence of multimorbidity of internet addiction and depressive symptoms among middle school students ranged from 2.7% to 3.5%. The prevalence of internet addiction ranged from 4.7% to 6.0%, while the prevalence of depressive symptoms ranged from 18.7% to 25.1%. Multivariate logistic regression showed that boarding students ( OR=1.34 , 95% CI: 1.26-1.42), low-frequency ( OR=1.59, 95% CI: 1.46-1.73), and high-frequency sugary drink consumption ( OR=3.91, 95% CI: 3.55-4.31) increased the risk of multimorbidity among middle school students. In contrast, higher frequencies of moderate-to-high-intensity exercise (medium: OR=0.54, 95% CI: 0.50-0.58; high: OR=0.49, 95% CI: 0.44-0.55) and sufficient sleep ( OR=0.52, 95% CI: 0.49-0.56) were protective factors. From 2018 to 2023, there was no significant change in the trend of multimorbidity prevalence among middle school students ( χ2trend=3.82, P=0.051). The prevalence of internet addiction showed an upward trend ( χ2trend=20.54, P<0.001), while depressive symptoms showed a downward trend ( χ2trend=181.41, P<0.001). Conclusion:The prevalence of internet addiction and depression symptoms among middle school students in Zhejiang Province remains stable from 2018 to 2023. The prevalence of internet addiction shows an upward trend, while the prevalence of depression symptoms shows a downward trend. The risk of multimorbidity is related to students′ boarding, consumption of sugary drinks, lack of exercise, and insufficient sleep.
