Objective:To assess the application value of one-hour post-load glucose (1hPG) for detecting prediabetes among individuals with high risk of type 2 diabetes mellitus (T2DM).Methods:The study was conducted between August 2023 and January 2024, and individuals with a high risk of T2DM were invited to receive an oral glucose tolerance test (OGTT), structural questionnaires, physical measurements, and other biochemical examinations. The fasting, one-, and two-hour glucose and insulin were tested. According to the 1hPG cut point on hyperglycemia suggested by International Diabetes Federation (IDF), normal glucose tolerance (NGT) and prediabetes were further divided into two subgroups, respectively, i.e., NGT with 1hPG<8.6 mmol/L (NGT-1hPG-normal), NGT with 1hPG≥8.6 mmol/L (NGT-1hPG-high), prediabetes with 1hPG<8.6 mmol/L (PDM-1hPG-normal), and prediabetes with 1hPG≥8.6 mmol/L (PDM-1hPG-high). The insulin release curve was drawn by the groups as above. Insulin resistance was evaluated by homeostasis model assessment for insulin resistance (HOMA-IR), and β-cell secretory function was evaluated by homeostasis model assessment for β cell function (HOMA-β)/HOMA-IR. Spearman rank correlation analysis was used to calculate the correlation coefficients among 1hPG, 2hPG and HOMA indices, and Steiger′s Z test was used to compare the difference between two correlation coefficients. Receiver operating characteristics (ROC) curves and area under the curve (AUC) were used to assess the accuracy of 1hPG for detecting prediabetes. Results:A total of 2 469 subjects consisting of 1 485 men (60.1%) and 984 (39.9%) women, with a mean age of (45.76±6.20) years, of which 1 844 (74.7%) had 1hPG≥8.6 mmol/L. The prevalence of 1hPG≥8.6 mmol/L was 46.8%, 93.0% and 99.8% in individuals with NGT, prediabetes and newly diagnosed T2DM, respectively ( χ 2=763.78, P<0.001). The insulin release curve showed that insulin secretion increased rapidly in subjects with NGT-1hPG-high, and peaked at one hour, then decreased rapidly, with a significantly higher level of one- and two-hour insulin than those with NGT-1hPG-normal ( P<0.001). Compared to individuals with NGT-1hPG-normal, the counterparts with NGT-1hPG-high exhibited higher HOMA-IR and lower adjusted HOMA-β ( P<0.001). Spearman rank correlation analysis showed that the correlation coefficient of 1hPG with HOMA-IR was similar to the correlation coefficient of 2hPG with HOMA-IR (0.493 vs. 0.480, P=0.550), while the correlation of 1hPG with adjusted HOMA-β was significantly stronger than that of 2hPG (-0.692 vs. -0.587, P<0.001). Excluding patients with T2DM, according to the cut point recommended by IDF, the AUC of 1hPG≥8.6 mmol/L for detecting prediabetes was 0.731 (95% CI: 0.714-0.748), and the sensitivity and specificity were 0.930 and 0.532, respectively, with the kappa value of 0.45. Conclusion:1hPG is closely related to insulin resistance and islet function, and there′s substantial value for individuals with a high risk of T2DM to detect prediabetes by using the 1hPG cut points recommended by IDF.

Objective:To investigate the effect and mechanism of circ_0000285 on regulating the proliferation and apoptosis of radiotherapy-resistant (RR) cells in cervical cancer.Methods:The RR cervical cancer cell lines HeLa-RR and SiHa-RR were constructed by gradually increasing the dose of X-ray irradiation. After transfection and/or 5 Gy X-ray irradiation, both HeLa-RR and SiHa-RR cells were divided into the control, si-circ_0000285, 5 Gy, si-circ_0000285+5 Gy, si-circ_0000285+miR-4731-5p inhibitor+5 Gy and si-circ_0000285+ miR-4731-5p inhibitor+si-FOXM1+5 Gy groups, respectively. Cell proliferation was detected using CCK-8 assay. The expression of circ_0000285 in cervical cancer cells HeLa and SiHa, as well as RR cervical cells HeLa-RR and SiHa-RR was measured by real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR). The targeting relationship between circ_0000285 and miR-4731-5p as well as the targeting relationship between miR-4731-5p and forkhead box M1 ( FOXM1) were assessed by dual-luciferase reporter gene assay. The expression of FOXM1 protein was detected by Western blot. Cell apoptosis was evaluated by flow cytometry. Results:CCK-8 assay confirmed the successful construction of radioresistant cervical cancer cells HeLa-RR and SiHa-RR. The expression of circ_0000285 in HeLa-RR and SiHa-RR cells was significantly higher than that in HeLa and SiHa cells. Dual-luciferase reporter gene assay showed that miR-4731-5p was the target gene of circ_0000285, and FOXM1 was the target gene of miR-4731-5p. Compared with the control group, the cell proliferation level of si-circ_0000285 group ( t=6.12, 9.80, P=0.004, 0.001) and si-circ_0000285+5 Gy group ( t=2.45,15.93, P=0.071, <0.001) in HeLa-RR and SiHa-RR cells were significantly decreased, and the apoptosis rate were significantly increased ( t=10.14, 17.78, P=0.001, <0.001; t=14.43, 31.44,both P<0.001). The cell proliferation ability of si-circ_0000285+5 Gy group in HeLa-RR and SiHa-RR cells was significantly higher than that of si-circ_0000285 group ( t=3.67, 6.12, P=0.021, 0.004), and the apoptosis rate was significantly higher than that in the si-circ_0000285 group ( t=8.96, 11.07, P=0.001, <0.001). Compared with the si-circ_0000285+5 Gy group, the proliferation ability of si-circ_0000285+miR-4731-5p inhibitor+5 Gy group in HeLa-RR and SiHa-RR cells was significantly decreased ( t=19.61, 12.25, both P<0.001), and the apoptosis rate was significantly decreased ( t=13.74, 29.78, both P<0.001). Compared with the si-circ_0000285+miR-4731-5p inhibitor+5 Gy group, the proliferation ability of si-circ_0000285+miR-4731-5p inhibitor+si-FOXM1+5 Gy group in HeLa-RR and SiHa-RR cells was significantly decreased ( t=2.45, 15.93, P=0.071, <0.001), and the apoptosis rate was significantly increased ( t=19.56, 35.71, both P<0.001). Conclusions:Knocking down circ_0000285 in combination with X-ray irradiation can significantly inhibit the proliferation of cervical cancer cells and promote cell apoptosis, and the mechanism may be that circ_0000285 regulates the miR-4731-5p/FOXM1 signaling axis.

This study analyzed soil-transmitted nematode infection surveillance data for children 3-9 years of age in Shaanxi Province from 2016 to 2023,to provide a scientific basis for control strategies for soil-transmitted nematode infections in children in the province.Since 2016,according to the requirements of the National Schistosomiasis and Soil-transmitted Nematode Surveillance Program(Trial),several counties and districts in Shaanxi Province were selected as surveillance sites every year.According to geo-graphical position,the surveillance sites were divided into five areas:east,west,south,north and middle,and one administrative vil-lage(community)was selected in each area for monitoring.The eggs of soil-transmitted nematodes(hookworm,Ascaris lumbricoides,Trichuris trichiura,and Enterobius vermicularis)were detected with the Kato-Katz technique in children 3-9 years of age at each sur-veillance site,and the eggs of Enterobius vermicularis were detected again with the cellophane tape anal swab method.The infection rate and intensity for E.vermicularis were calculated.Detection was performed in 12 462 children 3-9 years old at 75 surveillance sites in Shaanxi Province from 2016 to 2023;84 cases of soil-borne nematode infections were detected,and the overall infection rate was 0.67%.The infection rates for Ascaris lumbricoides and E.vermicularis were 0.18%(22/12 462)and 0.50%(62/12 462),respec-tively,and the infection rates for Trichuris trichiura and hookworm were not found.The infection rates of soil-transmitted nematodes in children were 1.28%(16/1 250),0.16%(2/1 252),1.25%(17/1 365),1.20%(18/1 494),0.17%(2/1 169),1.45%(20/1 382),0.00,and 0.36%(9/251),respectively.A linear trend was observed among years(χ2=11.973,P<0.001).The infection rates in the Weifen Basin ecological region,Loess Plateau ecological region,and Qinba Mountains ecological region were 0.51%,1.19%,and 0.72%,respectively,and the differences were statistically significant(χ2=9.726,P=0.008).Significant differences in infection rates were observed among scattered children(1.63%),preschool children(0.66%),and students(0.57%)(χ2=11.189,P=0.004).No significant differences in infection rates were observed by gender,age,and education level.Compared with the infection rates in the entire country and other provinces,the infection rate of soil-transmitted nematodes among children in Shaanxi Province was low,and the main infection species were Ascaris lumbricoides and E.vermicularis.The infection rates greatly varied within Shaanxi Prov-ince,possibly because of differences in economic development levels,children′s living habits,and personal hygiene status across re-gions.In the future,comprehensive control measures should be taken to strengthen the monitoring and control of key areas,popula-tions,and parasite species.

Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.

Objective:A two-sample bidirectional Mendelian randomization (MR) analysis was used to analyze the risk factors related to sunburn.Methods:Data were downloaded from the Gene-Wide Association Studies (GWAS) of the IEU Open GWAS project, and a two-sample bidirectional MR was conducted. In the forward MR analysis, the exposure factors were skin color, ease of skin tanning, skin pigmentation, facial aging, atopic dermatitis, contact dermatitis, urticaria, and education attainment, while the outcome factor was sunburn. In the reverse MR analysis, the exposure factor was sunburn, while the outcome factors were skin color, ease of skin tanning, skin pigmentation, facial aging, atopic dermatitis, contact dermatitis, urticaria, and education attainment. The data were analyzed using the "TwoSampleMR" package in R version 4.2.3. The result of the MR analysis were interpreted using the odds ratio ( OR) and the corresponding 95% confidence interval (95% CI), and a P-value <0.05 was considered statistically significant. In the analysis, we set a significance threshold of P-value<5×10 -8 (if sufficient instrumental variables cannot be obtained, the threshold will be adjusted to P-value<5×10 -6), eliminated linkage disequilibrium (with R2<0.001 and within a regional range of 10 000 kb), and screened single nucleotide polymorphisms (SNPs) that were significantly related to the research content, which would be set in the analysis as instrumental variables (IVs). For eligible IVs, a MR was conducted using the MR Egger, Weighted median, Inverse variance weighted (IVW), Simple mode, and Weighted mode method to explore the causal relationships between sunburn and various factors. The result obtained by the IVW method were taken as the main outcome indicator and summarized into a forest plot, while other method were used to supplement the IVW result. The heterogeneity of the IVs was evaluated by the Cochran Q-test. The direction of the causal effect and heterogeneity were evaluated through the scatter plot. The sensitivity of the result was analyzed by the leave-one-out test. The funnel plot was used to assess the potential bias. Results:9 851 867 SNPs related to skin color, 9 851 867 SNPs related to ease of skin tanning, 11 972 414 SNPs related to skin pigmentation, 9 851 867 SNPs related to facial aging, 16 121 213 SNPs related to atopic dermatitis, 24 191 078 SNPs related to contact dermatitis, 24 187 496 SNPs related to urticaria, 11 972 619 SNPs related to education attainment were obtained from the GWAS database. A total of 11 976 212 SNPs were obtained from the sunburn dataset. In the forward MR analysis, the IVW result showed a significant negative correlation between skin color and sunburn ( OR=0.68, 95% CI: 0.66-0.70, P<0.001); and a significant positive correlation between the ease of skin tanning, skin pigmentation, facial aging, atopic dermatitis, contact dermatitis, education attainment, and sunburn (ease of skin tanning: OR=1.30, 95% CI: 1.29-1.32, P<0.001; skin pigmentation: OR=1.76, 95% CI: 1.66-1.87, P<0.001; facial aging: OR=2.25, 95% CI: 1.67-3.04, P<0.001; atopic dermatitis: OR=1.02, 95% CI: 1.00-1.03, P=0.010; contact dermatitis: OR=1.01, 95% CI: 1.00-1.01, P=0.031; education attainment: OR=1.29, 95% CI: 1.22-1.36, P<0.001); while urticaria was not statistically significant ( P=0.056). The Cochran Q-test and scatter plot showed that there was a significant negative correlation between skin color and sunburn and a positive correlations between the ease of skin tanning, skin pigmentation, facial aging, atopic dermatitis, contact dermatitis, education attainment and sunburn. There was some heterogeneity among the IVs in research. The result of the leave-one-out test showed that no SNPs had a distinct impact on the causal effect, and the result of the forward MR analysis were relatively stable. The result of the funnel plot showed that the included SNPs were symmetrically distributed, and there was no potential bias in the result. In the reverse MR analysis, the IVW result showed a significant negative correlation between sunburn and skin color ( OR=0.16, 95% CI: 0.12-0.21, P<0.001); and a significant positive correlation between sunburn and ease of skin tanning, skin pigmentation, facial aging (ease of skin tanning: OR=26.78, 95% CI: 20.52-34.93, P<0.001; skin pigmentation: OR=3.12, 95% CI: 2.57-3.78, P<0.001; facial aging: OR=1.30, 95% CI: 1.24-1.37, P<0.001); while atopic dermatitis ( P=0.477), contact dermatitis ( P=0.318), urticaria ( P=0.328) and education attainment ( P=0.627) as outcome factors were not statistically significant. The Cochran Q-test and scatter plot showed that there was a significant negative correlation between sunburn and skin color and a positive correlations between sunburn and ease of skin tanning, skin pigmentation, facial aging. There was some heterogeneity among the IVs in research. The result of the leave-one-out test showed that no SNPs had a distinct impact on the causal effect, and the result of the reverse MR analysis were relatively stable. The result of the funnel plot showed that the included SNPs were symmetrically distributed, and there was no potential bias in the result . Conclusions:Skin color and sunburn are protective factors against each other; ease of skin tanning, skin pigmentation, and facial aging are bidirectional risk factors of sunburn; atopic dermatitis, contact dermatitis, and education attainment are risk factors of sunburn.

Cytoglobin(Cygb)is a recently discov-ered astrocyte specific globin that is widely distrib-uted in mammalian visceral organs such as the lung,heart,spleen,liver,pancreas,stomach,small intestine,kidney,neuron,and bone tissue.It plays an important role in clearing reactive oxygen spe-cies,nitric oxide and nitrite signal transduction,al-leviating oxidative stress,anti-fibrosis,regulation of cell apoptosis and treatment of cancer,etc.It is worth noting that the anti-fibrosis role of Cygb has attracted increasing attention in recent years.The existing research has involved various fibrotic dis-eases such as the liver,pancreas,kidney,spleen,etc.,especially in the study of liver fibrosis,which has made great progress.This article system re-views the role of Cygb in various fibrotic diseases,with a focus on its mechanism of alleviating oxida-tive stress.Although the application of Cygb in fi-brotic diseases is still in its infancy and the underly-ing mechanisms still require extensive research and exploration,there is no doubt that Cygb can serve as a promising therapeutic target,with the poten-tial to be widely used in the prevention and treat-ment of fibrotic diseases.

In the reverse MR analysis, the IVW result showed a significant negative correlation between sunburn and skin color ( OR=0.16, 95% CI: 0.12-0.21, P<0.001); and a significant positive correlation between sunburn and ease of skin tanning, skin pigmentation, facial aging (ease of skin tanning: OR=26.78, 95% CI: 20.52-34.93, P<0.001; skin pigmentation: OR=3.12, 95% CI: 2.57-3.78, P<0.001; facial aging: OR=1.30, 95% CI: 1.24-1.37, P<0.001); while atopic dermatitis ( P=0.477), contact dermatitis ( P=0.318), urticaria ( P=0.328) and education attainment ( P=0.627) as outcome factors were not statistically significant. The Cochran Q-test and scatter plot showed that there was a significant negative correlation between sunburn and skin color and a positive correlations between sunburn and ease of skin tanning, skin pigmentation, facial aging. There was some heterogeneity among the IVs in research. The result of the leave-one-out test showed that no SNPs had a distinct impact on the causal effect, and the result of the reverse MR analysis were relatively stable. The result of the funnel plot showed that the included SNPs were symmetrically distributed, and there was no potential bias in the result . Conclusions:Skin color and sunburn are protective factors against each other; ease of skin tanning, skin pigmentation, and facial aging are bidirectional risk factors of sunburn; atopic dermatitis, contact dermatitis, and education attainment are risk factors of sunburn.

Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.
