Objective To investigate the association between the Chinese visceral adiposity index (CVAI) and diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension among elderly people in Hebei Province. Methods In 2020, a stratified multi-stage random sampling was used to conduct questionnaire survey, physical examination and laboratory detection among permanent residents of 10 monitoring sites in Hebei Province. Logistic regression was used to analyze the association between CVAI and diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension. The area under the ROC curve (AUC) was used to evaluate the predictive value of CVAI for diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension. Results The detection rates of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension were 19.8%, 74.6%, 78.2%, and 16.2%, respectively. Multivariate logistic regression analysis showed that compared with the lowest quartile of CVAI group Q1, the OR (95% CI) of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension in the highest quartile Q4 group were 3.55 (2.58~4.89), 2.52 (1.92~3.31), 3.09 (2.31~4.12), and 4.92 (3.40~7.12), respectively. The ROC curve results showed that CVAI had the best predictive value in the diagnosis of diabetes with hypertension, and the optimized critical values in males and females were 128.54 and 141.88, respectively. Conclusion The detection rates of diabetes mellitus and hypertension are high in the elderly population in Hebei Province. CVAI is positively associated with the risk of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension among the elderly in Hebei. CVAI has the strongest prediction ability for diabetes with hypertension.

Objective The high post-surgery recurrence rate of endometriosis(EMs)has emerged as a challenge in the long-term manaagement of the condition.This study is aimed at investigating the mechanisms of Neiyiting(NYT)decoction in preventing postoperative recurrence of EMs.Methods An animal model of EMs postoperative recurrence and a model of endometrial stromal cells(hEM15A)cocultured with macrophages(RAW 264.7 cell line)were established for both in vivo and in vitro experiments.An autotransplantation method was used to establish a rat model of EMs.The rats were divided into 4 groups(6 rats per group)and received the corresponding treatments:a Model group receiving distilled water,a Gestrinone group receiving gestrinone at 0.325 mg/kg,a low-dose NYT(NYT-L)group receiving NYT decoction at 5.04 g/(kg-d),and a high-dose NYT(NYT-H)group receiving NYT decoction at 10.08 g/(kg-d).The treatment was administered for 3 weeks via intragastric gavage.In addition,6 SD rats were randomly selected for the control group(Control group),and were given distilled water for 3 weeks via intragastric gavage.The sizes and pathological changes of recurrent lesions in EMs rats were observed.Immunohistochemistry and qRT-PCR were performed to assess the expression of M1 macrophage marker CD86 protein and mRNA in vivo.Additionally,immunohistochemistry and qRT-PCR were used to assess the expression of indicator proteins related to the triggering receptor expressed on myeloid cells 1(TREM1)/Toll-like receptor 4(TLR4)/nuclear factor kappa B(NF-κB)signaling pathway and mRNA.The proliferation of hEM15A cells in the coculture experiment was observed.Flow cytometry was performed to determine the polarization of RAW264.7 macrophages,and qRT-PCR was used to determine the expression levels of inducible nitric oxide synthase(iNOS)and interleukin 1β(IL-1β)mRNA.Western blot was performed to determine the expression of signaling pathway-related indicator proteins in vitro.ELISA was performed to determine the levels of inflammatory factors in vitro.Results Compared with the Model group,the volume of recurrent lesions in the NYT-H group was reduced(P＜0.01).Findings from the macrophage M1 polarization assessment showed that the expression levels of CD86 protein and mRNA in the recurrent lesions of the Model group were higher than those in the control group(P＜0.01).The expression levels of CD86 protein and mRNA in the recurrent lesions of the NYT-H group were lower than those of the Model group(P＜0.01).In addition,the RAW 264.7 cell experiment further verified that NYT decoction could reduce the number of CD86-positive macrophages induced by plasmids overexpressing TREM1 and reduce the expression of IL-1β and iNOS mRNA(P＜0.01).The results of the hEM15A cell proliferation assay showed that NYT decoction down-regulated KI-67 protein expression in hEM15A cells induced by macrophage M1 polarization(P＜0.01).The results of TREM1/TLR4/NF-κB signaling pathway showed that the protein and mRNA expression levels of TREM1,TLR4,and NF-κB in the recurrent lesions of the Model group were higher than those of the control group(P＜0.01).Compared with those in the Model group,the protein and mRNA expression levels of TREM1,TLR4,and NF-κB in the recurrent lesions of the NYT-H group were lower(P＜0.01).In addition,the coculture experiment of RAW264.7 and hEM15A cells further confirmed that NYT decoction reduced the expression of TREM1,TLR4,and P-P65 proteins(P＜0.01).Conclusion NYT decoction can inhibit macrophage M1 polarization through the TREM1/TLR4/NF-κB signaling pathway,improve the inflammation level,and inhibit the formation of ectopic endometrial lesions,thereby preventing postoperative recurrence of EMs.

Objective To investigate the molecular mechanism by which HMGA2 participates in the TGF-β/Smad pathway in the regulation of the proliferation, aggression, and metastasis of laryngeal cancer. Methods shRNA transfection was used to construct the HMGA2 knockdown laryngeal cancer TU686 cell model, and subcutaneous transplantation tumor model and tail vein metastasis tumor model were established in nude mice. Western blot was conducted to detect the expression of HMGA2 and TGF-β/Smad pathway-related molecules in cells and tumor tissues. Results The proliferation, invasion, and metastasis of TU686 cells with HMGA2 knockdown decreased. The expression of TGF-β, Smad2, Smad3, and phosphorylated Smad2/3 protein also decreased. TGF-β1 stimulation of the TGF-β/Smad pathway could partially offset the antitumor effect caused by HMGA2 knockdown. Through in vitro experiments, we determined that low expression of HMGA2 significantly inhibited the growth of subcutaneously transplanted tumors, and TGF-β1 stimulation of the TGF-β/Smad pathway reduced the tumor-inhibitory effect resulting from the low expression of HMGA2. In tail vein metastases of nude mice, E-cadherin expression was elevated but N-cadherin expression was reduced in the HMGA2 knockdown group, suggesting that HMGA2 could inhibit the progression of EMT. After TGF-β1 stimulated the TGF-β/Smad pathway, the EMT effect due to HMGA2 knockdown was lessened. Conclusion HMGA2 may promote the proliferation, invasion, and metastasis of laryngeal cancer by upregulating the TGF-β/Smad signaling pathway.

Objective:To analyze the disease burden of respiratory syncytial virus (RSV)- associated lower respiratory tract infection (LRTI) in Chinese children under one year of age from 1990 to 2021.Methods:Using the Global Burden of Disease (GBD) 2021 database ( https://vizhub.healthdata.org/gbd-results/), we calculated deaths, mortality, age-standardized mortality rates (ASMR), disability- adjusted life years (DALYs), DALY rates, and age-standardized DALY rates (ASDR) to assess the disease burden of RSV-associated LRTI in Chinese children under one year of age. Joinpoint regression modeling was employed to analyze temporal trends in disease burden in China from 1990 to 2021, with stratification by time, age, and sex. Comparisons were made with global and high socio-demographic index (SDI) regions. Results:In 2021, there were 324 deaths (95% UI: 179-539) from RSV-LRTI in Chinese infants under one year of age, with a mortality rate of 2.82 per 100 000 (95% UI: 1.55-4.69), ASMR of 0.10 per 100 000 (95% UI: 0.06-0.16), DALYs of 29 131.28 years (95% UI: 16 050.27-48 398.30), DALY rate of 253.56 per 100 000 (95% UI: 139.70-421.26), and ASDR of 6.70 per 100 000 (95% UI: 3.72-11.12). All metrics were lower than global levels but significantly higher than high-SDI regions. From 1990 to 2021, substantial reductions were observed in deaths, mortality rates, DALYs, and DALY rates of RSV-LRTI among children under one year of age in China, globally, and in high-SDI regions. China achieved ASMR and ASDR reductions of－95.91% (95% CI:－97.75% to－92.96%) and－96.70% (95% CI:－98.19% to－94.33%), comparable to high-SDI regions but exceeding global averages. Joinpoint analysis showed average annual percentage changes (AAPC) in ASMR of－9.80% (95% CI:－10.45% to－9.14%) for China,－5.38% (95% CI:－5.83% to－4.91%) globally, and－7.13% (95% CI:－9.07% to－5.14%) for high-SDI regions (all P<0.001). The AAPC for ASDR were－10.41% (95% CI:－11.01% to－9.79%),－5.40% (95% CI:－5.82% to－4.97%), and－7.09% (95% CI:－9.70% to－4.41%) for China, the global average, and high-SDI regions, respectively, with the most pronounced decline occurring between 2019 and 2021 (ASMR decreased by 53.33%, 45.81%, and 61.31%, while ASDR declined by 52.50%, 44.54%, and 58.88% in China, globally, and in high-SDI regions, respectively). In 2021, both China and high-SDI regions exhibited declining mortality and DALY rates for RSV-LRTI with increasing age among children under one year, while neonates younger than 28 days consistently demonstrated the highest burden metrics. The rate of decline was comparable between China and high-SDI regions, with both exceeding the global average. Furthermore, from 1990 to 2021, male infants under one year of age in China, globally, and in high-SDI regions consistently showed higher overall trends in deaths, mortality rates, DALY, and DALY rates for RSV-LRTI compared to female infants. Conclusions:Although China's RSV-LRTI disease burden in infants under one year remains lower than global levels but higher than high-SDI regions, the country achieved reduction rates comparable to high-SDI regions, exceeding global averages. RSV-LRTI continue to pose significant health threats to neonates and male infants, necessitating age-specific and sex-specific prevention strategies.

Cantharidin (CTD), a natural compound used to treat multiple tumors in the clinic setting, has been limited due to acute kidney injury (AKI). However, the major cause of AKI and its underlying mechanism remain to be elucidated. Serum creatinine (SCr) and blood urea nitrogen (BUN) were detected through pathological evaluation after CTD (1.5 mg/kg) oral gavage in mice in 3 days. Kidney lipidomics based on ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to investigate lipids disorder after CTD exposure in mice. Then, spatial metabolomics based on matrix-assisted laser desorption/ionization-mass spectrometry imaging (MALDI-MSI) was used to detect the kidney spatial distribution of lipids. Integrative analysis was performed to reveal the spatial lipid disorder mechanism and verify key lipids in vitro. The results showed that the levels of SCr and BUN were increased, and tubular necrosis was observed in mouse kidneys, resulting in acute tubular necrosis (ATN) in CTD-induced AKI. Then, lipidomics results revealed that after CTD exposure, 232 differential lipid metabolites and 11 pathways including glycerophospholipid (GP) and sphingolipid (SL) metabolism were disrupted. Spatial metabolomics revealed that 55 spatial differential lipid metabolites and nine metabolic pathways were disturbed. Subsequently, integrative analysis found that GP metabolism was stimulated in the renal cortex and medulla, whereas SL metabolism was inhibited in the renal cortex. Up-regulated lysophosphatidylcholine (LysoPC) (18:2(9Z,12Z)), LysoPC (16:0/0:0), glycerophosphocholine, and down-regulated sphingomyelin (SM) (d18:0/16:0), SM (d18:1/24:0), and SM (d42:1) were key differential lipids. Among them, LysoPC (16:0/0:0) was increased in the CTD group at 1.1196 μg/mL, which aggravated CTD-induced ATN in human kidney-2 (HK-2) cells. LysoPC acyltransferase was inhibited and choline phosphotransferase 1 (CEPT1) was activated after CTD intervention in mice and in HK-2 cells. CTD induces ATN, resulting in AKI, by activating GP metabolism and inhibiting SL metabolism in the renal cortex and medulla, LysoPC (16:0/0:0), LysoPC acyltransferase, and CEPT1 may be the therapeutic targets.

Objective:To explore the mediating role of work engagement in the relationship between fear of missing out (FoMO) and work well-being among standardized training nurses, and to examine the moderating role of feedback-seeking behavior.Methods:Using convenience sampling, a total of 293 standardized training nurses were recruited from two ClassⅢ Grade A hospitals in Wuhan, Hubei Province, from April to May 2024. Participants completed a demographic questionnaire, the Employee Fear of Missing Out Scale, Feedback-Seeking Behavior Scale, Short Version of the Utrecht Work Engagement Scale, and the Nurse Work Well-Being Scale.Results:FoMO was negatively correlated with work well-being. Work engagement partially mediated the relationship between FoMO and work well-being, accounting for 45.0% (-0.18/-0.40) of the total effect. Feedback-seeking behavior moderated both the relationship between FoMO and work engagement and the overall mediation pathway.Conclusions:FoMO among standardized training nurses affects their work well-being both directly and indirectly through work engagement. This mechanism is moderated by feedback-seeking behavior, highlighting the importance of enhancing work engagement and constructive feedback practices to improve well-being.

Objective To investigate the predictive value of bone metabolism parameters on cardiac autonomic nervous system function in patients with type 2 diabetes mellitus(T2DM).Methods A total of 328 patients with T2DM hospitalized in the Department of Endocrinology of Gansu Provincial People's Hospital were enrolled in this study from October 2022 to October 2023.According to the serum 25(OH)D level,all the participants were divided into<10 ng/ml group(n=80),10～20 ng/ml group(n=173),and 20～30 ng/ml group(n=75).Biochemical indicators,bone metabolic parameters,left ventricular mass(LVM)and left ventricular mass index(LVMI)were compared.Time domain indicators ofheart rate variability(HRV)in 24 h holter electrocardiogram,including the global standard deviation of normal sinus RR interval(SDNN),sinus RR interval mean standard deviation(SDANN),and normal continuous sinus RR interval difference root mean square(RMSSD).Meanwhile,adjacent RR interval difference>50 ms as a percentage of the total inter-period(PNN50),HRV triangle index,standard deviation of the difference between the length of the entire adjacent NN interperiod(SDSD),and 24 h holter electrocardiogram HRV time-domain relevant indicators were compared among the three groups.The influence of bone metabolism parameters on cardiac autonomic nervous function and their correlation were analyzed,and the optimal cutting point of cardiac autonomic nervous function was predicted by receiver operating characteristic(ROC)curve.Results SBP,heart rate(HR),FPG,PWV,PTH and β-CTX in groups of 10 ng/ml,10～20 ng/ml and 20～30 ng/ml decreased in turn(P<0.05),while HDL-C,ABI,25(OH)D,Ca2+and PNN50 decreased.Correlation analysis between Spearman and Pearson showed that 25(OH)D was positively correlated with SDNN,HRV triangle index,PNN50 and rMSSD(P<0.01).Logistic regression analysis showed that 25(OH)D,Ca2+and HR were the influencing factors of cardiac autonomic nervous dysfunction in patients with T2DM.The ROC curve analysis showed that the areas under the ROC curve of 25(OH)D,Ca2+and HR were 0.791,0.607 and 0.629,respectively,with sensitivity of 73.4%,53.2%and 38.7%,and specificity of 74.0%,93.6%and 81.4%,respectively.Conclusions 25(OH)D is the influencing factor of cardiac autonomic nervous dysfunction in patients with T2DM,and patients with high degree of deficiency are more prone to cardiac autonomic nervous dysfunction.

Objective:To investigate the effects of insulin-like growth factor 2 (IGF-2) on the expression of postsynaptic density protein 95 (PSD95), synaptophysin-1 (SYN1), and synaptophysin (SYP) in the mouse visual cortex and visual function after monocular deprivation (MD).Methods:Sixty-four SPF male Kunming mice aged 3 weeks were randomly divided into 4 groups: normal control group, MD group, MD+ IGF-2 recombinant protein (MD+ IGF-2) group, and MD+ fluoxetine (FLX) group, with 16 mice in each group.The MD group, MD+ IGF-2 group and MD+ FLX group were treated with right eyelid suturing at the beginning of 3 weeks old and eyelid opening at the end of 5 weeks old.The MD+ IGF-2 group was intraperitoneally injected with IGF-2 recombinant protein during MD.The MD+ FLX group was given fluoxetine via drinking water for 4 weeks after eyelid opening.The normal control group and MD group were injected intraperitoneally with bovine serum albumin every day from 3 to 5 weeks of age.At the end of 5 and 9 weeks of age, subjective visual function was evaluated by fore paw touching ground reflex experiment.At the end of 9 weeks of age, objective visual function was assessed by flash visual evoked potentials.After the mice were sacrificed, the left visual cortex of mice in each group was taken, and the expression of PSD95, SYN1, and SYP was assessed by Western blot.This study was approved by the Ethics Committee of Hunan Children's Hospital (No.HCHDWLL-2022-16). The handling of experimental animals was carried out in accordance with the Guidelines for the Management and Use of Laboratory Animals in Hunan Children's Hospital.Results:At the end of 5 and 9 weeks of age, there were overall significant differences in the success rate of fore paw touching ground among different groups of mice ( F=4.83, 3.36; both P<0.05). At the end of 5 weeks of age, the success rate was lower in MD group and MD+ FLX group than in normal control group, and significantly higher in MD+ IGF-2 group than in MD group, with statistically significant differences (all P<0.05). At the end of 9 weeks of age, the success rate was lower in MD group than in normal control group, and significantly higher in MD+ IGF-2 group and MD+ FLX group than in MD group (all P<0.05). There was a significant overall difference in P2 wave amplitude in F-VEP examination among different groups of mice ( F=13.99, P<0.01). The P2 wave amplitude was significantly lower in MD group than in normal control group and MD+ IGF-2 group (both P<0.01). There was no significant difference in the P2 wave latency of F-VEP among the four groups of mice ( F=2.83, P=0.07). The relative expression levels of PSD95, SYN1 and SYP proteins were 1.00±0.41, 1.00±0.10 and 1.00±0.27 in normal control group, 0.32±0.27, 0.68±0.20 and 0.56±0.28 in MD group, 0.78±0.32, 0.91±0.18 and 0.94±0.22 in MD+ IGF-2 group, 0.89±0.65, 0.98±0.28 and 0.94±0.47 in MD+ FLX group, respectively.There were significant differences in levels of PSD95, SYN1 and SYP in mice visual cortex among different groups ( F=4.24, 5.32, 3.40; all P<0.05). The expressions of PSD95, SYN1 and SYP proteins in the visual cortex were lower in MD group than in normal control group, and higher in MD+ IGF-2 group than in MD group (all P<0.05). Conclusions:Administration of exogenous IGF-2 to mice that underwent MD during the critical period can maintain visual cortex plasticity and protect the visual function to a certain extent.
