Objective: To explore the association between vegetable intake with glucose and lipid metabolism levels among school aged children, so as to provide scientific basis for dietary intervention on children s metabolic health. Methods: Based on a natural population cohort in Jiulongpo District and Fengdu County of Chongqing, 2 133 school aged children aged 6-9 years were enrolled in the baseline survey in 2014, and 2 029 children completed the follow up in 2019. Questionnaire surveys were used to collect vegetable intake, general demographic and lifestyle data. Height, weight and waist circumference were measured, and glucose and lipid metabolism indicators such as fasting blood glucose (FBG), triglyceride (TG) and total cholesterol (TC), low densith lipoprotein triglyceride (LDL-C), high densith lipoprotein triglyceride (HDL-C) were detected. Mann-Whitney U test and Kruskal-Wallis H test were used for intergroup comparisons in multivariate analysis, and mixed effects linear regression model was used to analyze the association between vegetable intake and glucose and lipid metabolism. Results: The levels of FBG, TG, TC, HDL-C and LDL-C at baseline and follow up were [4.09(3.90,4.48), 0.84(0.60,1.14), 3.49(3.09,3.91), 1.25(1.09,1.46), 1.69 ( 1.39 ,2.02)；4.31(4.00,4.64), 0.92(0.71,1.22), 3.49(3.12,3.87), 1.36(1.16,1.57), 1.77(1.51,2.06)] mmol/L, respectively. Among these indicators, FBG, TG, HDL-C and LDL-C all increased significantly ( Z =-12.08, -7.82, -9.82, -5.37, all P < 0.01 ). The detection rate of low HDL-C levels at follow up (13.11%) was significantly lower than that at baseline (18.10%) ( χ 2=19.57, P <0.05). At baseline, there were significant differences in FBG, TC, TG, HDL-C and LDL-C among children with different vegetable intake levels ( H =68.47, 30.16, 11.02, 13.27, 44.70); at followup, only HDL-C showed significant intergroup differences ( H =13.10)(all P <0.05). Mixed effects linear regression model showed that after adjusting for confounding factors, vegetable intake was significantly negatively correlated with blood glucose levels among school aged children ( β=-0.03, 95%CI = -0.05 to -0.01, P <0.01). Conclusion Higher vegetable intake can independently reduce the risk of abnormal blood glucose in school aged children, which is of great significance for maintaining glucose metabolic health.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective To explore the mechanism of Modified Xiaoxianxiong Decoction(MXD)in"treating different diseases with the same method"for type 2 diabetes mellitus(T2DM)and obstructive sleep apnea(OSA)using network pharmacology and molecular docking.Methods Active components and related targets of the seven herbs in MXD(composed of Coptidis Rhizoma,Pinelliae Rhizoma,Trichosanthis Fructus,Bupleuri Radix,Salviae Miltiorrhizae Radix et Rhizoma,Paeoniae Radix Rubra,Astragali Radix)were retrieved and screened from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP).Swiss Target Prediction was used for target prediction of active components,followed by gene standardization using the UniProt database.Disease-related targets of T2DM and OSA were obtained from DisGeNET,OMIM,and GeneCards databases.A Venn diagram was used to identify overlapping targets between disease-related targets and active component-related targets,yielding potential therapeutic targets of MXD for both T2DM and OSA.The STRING database and Cytoscape 3.10.2 were employed to construct a protein-protein interaction(PPI)network and a"drug-component-target"network,respectively.Core active components and core targets were identified through network topology analysis.GO functional and KEGG pathway enrichment analyses were performed on potential targets using Metascape.Molecular docking validation was conducted using AutoDock to assess binding affinity between core targets and compounds.Results A total of 157 active components of MXD acted on 1 043 protein targets.After comparison with 1 798 OSA-related targets and 3 466 T2DM-related targets,253 potential therapeutic targets were identified.GO enrichment analysis revealed that these targets were primarily involved in biological processes such as upregulation of phosphorus metabolism,regulation of cell migration,circulatory system processes,and hormone level regulation.KEGG pathway analysis identified key pathways including Rap1,AGE-RAGE,cAMP,and Alzheimer's disease.PPI and"drug-component-target"network topology analysis screened 39 core targets(e.g.,IL-6,TNF,Akt1,IL-1β,EGFR)and core active components(e.g.,salvianolic acid B,tanshinone IIA,baicalin,curcumin).Molecular docking confirmed stable binding between these components and their corresponding target proteins.Conclusion The common pharmacodynamic basis of MXD in"treating different diseases with the same method"for T2DM and OSA includes active components such as salvianolic acid B,baicalin,and curcumin.The shared mechanism may involve key targets(e.g.,IL-6,TNF,Akt1)and modulation of signaling pathways such as Rap1,AGE-RAGE,and cAMP.

Objective To explore the value of serum matrix metalloproteinase 7 combined with glutamyl transferase and total bile acids in the diagnosis of biliary atresia.Methods 112 children hospitalized in Kunming Children's Hospital with the cholestatic jaundice from July 2023 to September 2024 were selected as the research subjects.According to the surgical exploration,intraoperative cholangiography,liver biopsy and follow-up,the children were divided into the biliary atresia group(BA)(n=52)and non-biliary atresia group(Non-BA)(n=60)respecvely.The age,gender,serum matrix metalloproteinase 7(MMP-7),glutamyl transferase(GGT),alanine aminative aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TB),direct bilirubin(DB),total bile acid(TBA)and aspartate aminotransferase/platelet index(APRI)were compared between the two groups.Statistically significant indicators were included in receiver operating characteristic curve(ROC)analysis,and the area under the ROC curve(AUC)and optimal diagnostic margin(Youden index)were calculated.Results There was no significant difference in age,ALT,AST,DB,TB and APRI levels between the two groups of patients(P>0.05);There was a difference in gender composition ratio between the two groups(P=0.006);MMP-7,GGT,TBA levels in the BA group were significantly higher than those in the Non-BA group,and the difference was statistically significant(P<0.05);the AUC of MMP-7,GGT,and TBA in diagnosing BA were 0.946(95%CI 0.897～0.996),0.857(95%CI 0.789～0.926),0.654(95%CI 0.552～0.755)respectively;When the cut-off value of MMP-7 was 22.37 ng/ml,the sensitivity and specificity for diagnosing BA were 0.923 and 0.933 respectively;When the cut-off value of GGT was 151.5 U/L,the sensitivity and specificity of diagnosing BA were 0.885 and 0.733 respectively;When the cut-off value of TBA was 119.5 μmol/L,the sensitivity and specificity of diagnosing BA were 0.788 and 0.500,respectively.The AUC of MMP-7+GGT and MMP-7+TBA combined to diagnose BA were 0.971(95%CI 0.946～0.997)and 0.943(95%CI 0.889～0.996)respectively.Conclusion Serum MMP-7 has the good diagnostic value as a single indicator for diagnosing BA;MMP-7 combined with GGT is better than a single indicator for diagnosing BA;MMP-7 combined with TBA cannot improve the diagnostic efficiency.

OBJECTIVES: This study aimed to investigate the impact of foam macrophages (FMs) on the intracellular survival of Mycobacterium tuberculosis (MTB) and identify the molecular mechanisms influencing MTB survival. METHODS: An in vitro FM model was established using oleic acid induction. Transcriptomic and metabolomic analyses were conducted to identify the key molecular pathways involved in FM-mediated MTB survival. RESULTS: Induced FMs effectively restricted MTB survival. Transcriptomic and metabolomic profiling revealed distinct changes in gene and metabolite expression in FMs during MTB infection compared with normal macrophages. Integrated analyses identified significant alterations in the cyclic adenosine monophosphate (cAMP) signaling pathway, indicating that its activation contributes to the FM-mediated restriction of MTB survival. CONCLUSIONS FMs inhibit MTB survival. The cAMP signaling pathway is a key contributor. These findings enhance the understanding of the role of FMs in tuberculosis progression, suggest potential targets for host-directed therapies, and offer new directions for developing diagnostic and therapeutic strategies against tuberculosis.

Objective:To analyze the comorbidity patterns between thyroid dysfunction and other common cardiometabolic diseases.Methods:In this cross-sectional study, 93 967 participants aged 18 years or older who underwent thyroid function tests at the Health Checkup Center of China-Japan Friendship Hospital between 2017 and 2024 were included. The comorbidity patterns between thyroid dysfunction and six common cardiometabolic diseases of obesity, diabetes, hypertension, dyslipidemia, hyperuricemia, and non-alcoholic fatty liver disease (NAFLD) were described systematicly. The logistic regression models was used to analyze the association between thyroid dysfunction and these cardiometabolic diseases.Results:The detection rates of subclinical hyperthyroidism, overt hyperthyroidism, subclinical hypothyroidism, and overt hypothyroidism in those participants was 1.9%, 0.9%, 3.7% and 1.1%, respectively. The proportion of the paticipants with subclinical hyperthyroidism, overt hyperthyroidism, subclinical hypothyroidism, and overt hypothyroidism who had at least one comorbid cardiometabolic disease was 67.5%, 64.8%, 73.5%, and 77.6%, respectively; the proportion of those participants with two or more concurrent cardiometabolic diseases was 38.6%, 36.7%, 42.8%, and 47.5%, respectively; and the proportion with three or more concurrent cardiometabolic diseases was 19.0%, 18.1%, 22.9%, and 27.5%, respectively. After adjusting for age and gender, the participants with overt hypothyroidism (≥2 comorbidities: OR=1.7, 95% CI: 1.5-1.9;≥3 comorbidities: OR=1.8, 95% CI: 1.5-2.1) or subclinical hypothyroidism (≥2 comorbidities: OR=1.3, 95% CI: 1.2-1.4;≥3 comorbidities: OR=1.3, 95% CI: 1.2-1.4) had a significantly higher risk of multiple cardiometabolic diseases when compared with euthyroid individuals. Analysis of comorbidity patterns revealed that individuals with overt hyperthyroidism ( OR=1.8, 95% CI: 1.0-3.1) and subclinical hyperthyroidism ( OR=1.5, 95% CI=1.0-2.2) had a significantly higher risk of the “NAFLD+hypertension” comorbidity complex when compared with euthyroid individuals. Similarly, individuals with overt hypothyroidism ( OR=1.7, 95% CI: 1.2-2.3) and subclinical hypothyroidism ( OR=1.3, 95% CI: 1.1-1.5) had a significantly higher risk of the “dyslipidemia+NAFLD+hyperuricemia” comorbidity complex when compared with euthyroid individuals. Conclusion:Individuals with thyroid dysfunction exhibit a high prevalence of comorbid cardiometabolic diseases, highlighting the need for future research on integrated management strategies for multimorbidity in this population.

Objective:To evaluate the efficacy of peritoneal dialysis (PD) in the treatment of acute kidney injury (AKI) in critically ill neonates.Methods:It was a retrospective study. The baseline characteristic data, PD protocols, PD catheter placement methods and clinical outcomes of AKI neonates who underwent PD in the General Hospital of Ningxia Medical University between July 2015 and December 2024 were collected and analyzed.Results:(1) Among the 8 neonates with AKI, gestational age was (30.38±6.02) weeks, and birth weight was 1 397.5 (839.0, 2 312.5) g, with 6 premature infants. The time from birth to AKI onset was 144 (48, 294) hours. The leading cause of AKI was sepsis (6/8). The treatment time of PD was (93.12±37.20) hours. (2) Renal function recovery: After PD treatment, urine output was significantly increased ( Z=-3.29, P<0.001), and serum creatinine was significantly decreased ( t=2.66, P=0.032). (3) Hyperkalemia: Six out of 8 patients presented with hyperkalemia, which significantly decreased after PD treatment ( t=3.37, P=0.008). (4) Acid-base balance:Five out of 8 neonates had metabolic acidosis, and 3 of 5 neonates achieved basically complete correction (including lactic acidosis). There was no statistically significant difference in acid-base balance indicators before and after PD treatment (all P>0.05). (5) PD-related complications: Two out of 8 patients experienced peritoneal dialysate leakage, and no other PD-related complications occurred. (6) Outcomes: The hospital stay was 27.0 (8.0, 57.5) days. Four out of 8 neonates survived, while the other 4 neonates died after withdrawal of treatment. The primary cause was multiple organ failure. Conclusions:PD is a safe and effective treatment for neonatal AKI, facilitating early renal recovery and correction of electrolyte and acid-base imbalances.

Purpose To quantitatively compare the diffusion parameters of mono-and biexponential diffusion-weighted imaging models,and to obtain optimal sets of b-values in diffusion-weighted MRI for obtaining monoexponential apparent diffusion coefficient(ADC)close to perfusion-insensitive intravoxel incoherent motion(IVIM)model ADC(ADCIVIM)in identifying of pulmonary solid benign and malignant lesions.Materials and Methods IVIM was performed in 40 patients with solid nodule and masse in Xi'an Gaoxin Hospital from July 2021 to August 2022 using a 3.0T MR imager.Two experienced diagnostic radiologists subjectively evaluated the IVIM images.A single index model was used to calculate ADC values(ADC0-1 000,ADC20-1 000,ADC50-1 000,ADC80-1 000,ADC150-1 000,ADC300-1 000,ADC500-1 000,ADC300,500,1 000,ADC300,800,1 000,ADC300,500,ADC300,800 and ADC300,1 000).The reference standard ADCIVIM value were calculated using a double-exponential model.The physician's measurements between two physicians were measured.The malignant and benign groups were compared and receiver operator characteristic curve for all parameters were analyzed.Results The measurement consistency of ADC values under b value sets and ADCIVIM was very good,and the intraclass correlation coefficient was more significant than 0.75.The differences between ADCIVIM and ADC values in each b group were statistically significant(t=-6.016--2.500,all P<0.05).The area under the curve(AUC)of ADCIVIM was the largest(0.906),with an optimal threshold of 1.271×10-3 mm2/s,a sensitivity of 80.0%and a specificity of 93.0%.The diagnostic efficacy close to ADCIVIM were ADC300,800(AUC=0.891),ADC50-1 000(AUC=0.827)and ADC300,800,1 000(AUC=0.795),respectively.The optimal threshold of ADC300,800 was 1.140×10-3 mm2/s,the sensitivity and specificity were 80.0%and 93.7%,respectively.Conclusion Combining b-values 300 s/mm2 and 800 s/mm2 is recommended as routine scanning parameters for identifying the insensitive monoexponential ADC between benign and malignant solid pulmonary lesions.

OBJECTIVES: To evaluate the application value of genetic newborn screening (gNBS) in the Yunnan region. METHODS: A prospective study was conducted with a random selection of 3 001 newborns born in the Yunnan region from February to December 2021. Traditional newborn screening (tNBS) was used to test biochemical indicators, and targeted next-generation sequencing was employed to screen 159 genes related to 156 diseases. Positive-screened newborns underwent validation and confirmation tests, and confirmed cases received standardized treatment and long-term follow-up. RESULTS: Among the 3 001 newborns, 166 (5.53%) were initially positive for genetic screening, and 1 435 (47.82%) were genetic carriers. The top ten genes with the highest variation frequency were GJB2 (21.29%), DUOX2 (7.27%), HBA (6.14%), GALC (3.63%), SLC12A3 (3.33%), HBB (3.03%), G6PD (2.94%), SLC25A13 (2.90%), PAH (2.73%), and UNC13D (2.68%). Among the initially positive newborns from tNBS and gNBS, 33 (1.10%) and 47 (1.57%) cases were confirmed, respectively. A total of 48 (1.60%) cases were confirmed using gNBS+tNBS. The receiver operating characteristic curve analysis demonstrated that the areas under the curve for tNBS, gNBS, and gNBS+tNBS in diagnosing diseases were 0.866, 0.982, and 0.968, respectively (P<0.05). DeLong's test showed that the area under the curve for gNBS and gNBS+tNBS was higher than that for tNBS (P<0.05). CONCLUSIONS gNBS can expand the range of disease detection, and its combined use with tNBS can significantly shorten diagnosis time, enabling early intervention and treatment.

OBJECTIVE: To explore the safety and efficacy of high-dose etoposide (VP-16) combined with recombinant human granulocyte colony-stimulating factor (rhG-CSF) as salvage mobilization for peripheral blood stem cells (PBSC) in newly diagnosed multiple myeloma (NDMM) patients. METHODS: From April 2021 to May 2023, eight NDMM patients who had failed to yield sufficient PBSC during initial mobilization with high-dose cyclophosphamide (CTX) combined with rhG-CSF underwent salvage mobilization with 1.2 g/m2 etoposide combined with rhG-CSF 10 μg/(kg·d). The effects and adverse reactions of initial mobilization and salvage mobilization were analyzed. RESULTS: For salvage mobilization and initial mobilization, the numbers of PBSC collections were 16 and 18, respectively. The mean value of total collected CD34⁺ cells were (11.90±5.75)×10⁶/kg and (1.67±0.75)×10⁶/kg (P =0.0010) in salvage mobilization group and initial mobilization group, respectively. The proportion of patients with a total collection of CD34⁺ cell count≥2×10⁶/kg were 100% and 37.5% (P =0.0625), and the proportion of patients with a total collection of CD34⁺ cell count≥5×10⁶/kg were 87.5% and 0% (P =0.0156) in salvage mobilization group and initial mobilization group, respectively. For five patients who underwent high-dose CTX initial mobilization but had a total CD34⁺ cell count < 2×10⁶/kg, successful collection was achieved through salvage mobilization with high-dose VP-16. Salvage mobilization with high-dose VP-16 was scheduled 2-3 weeks after failure of CTX mobilization. Adverse reactions of high-dose VP-16 mobilization did not increase compared to the initial mobilization with high-dose CTX. CONCLUSION As a salvage mobilization regimen, VP-16 1.2 g/m² combined with rhG-CSF is safe and highly effective in NDMM patients who failed to initial mobilization with high-dose CTX combined with rhG-CSF.
