ObjectiveTo explore the long-term dynamic trajectories of fasting blood glucose （FBG） and insulin resistance （IR） in patients with type 2 diabetes mellitus （T2DM） and their influencing factors. MethodsThis retrospective cohort study included 1 896 T2DM patients registered at Tongren Hospital from May 2020 to May 2025. Based on longitudinal follow-up data of FBG and fasting insulin， joint latent class mixed models （JLMM） were applied to identify FBG-IR trajectories. Univariate and multinomial logistic regression was used to examine demographic characteristics， lifestyle， and clinical determinants of trajectory type. ResultsFour distinct FBG-IR trajectories were identified： stable FBG-IR （9.76%）， rising FBG-stable IR （5.01%）， stable FBG-elevated IR （75.90%）， and elevated FBG-IR （9.34%）. Compared with the stable FBG-IR group， age ≥60 years was protective against the elevated FBG-stable IR trajectory （OR=0.55， 95%CI：0.33-0.92， P=0.023）. Highereducation increased the risk of stable FBG-elevated IR （OR=1.40， 95%CI：1.01-1.94， P=0.046）. Abnormal blood pressure was associated with lower risks of stable FBG-elevated IR （OR=0.66， 95%CI：0.48-0.92， P=0.013） and elevated FBG-IR （OR=0.48， 95%CI：0.31-0.74， P=0.001）. Non-drinkers were less likely to belong to the stable FBG-elevated IR trajectory （OR=0.39， 95%CI：0.16-0.95， P=0.038）. ConclusionsThe evolution trajectory of FBG and IR in T2DM patients shows significant heterogeneity. The majority of patients have a deterioration of IR first. Age， education level， blood pressure， and alcohol consumption are the main influencing factors. Joint assessment of FBG and IR is helpful for early identification of high-risk individuals and guiding individualized intervention.

Objective:To explore the effect of proxy online health information seeking based on theory of planned behavior(TPB) of rural maternal for breast feeding guidance. The aim is to provide a theoretical basis for improving the rate of exclusive breast feeding among rural mothers.Methods:Using a quasi experimental research method and convenience sampling method, the study selected postpartum women and their primary caregivers who gave birth at Maoming Dianbai Maternal and Child Health Care hospital from October 2023 to April 2024 as the research subjects. According to the admission time, 47 parturients and their primary caregiver who gave birth between October and December 2023 were designated as the control group, while 50 parturients and their primary caregiver who gave birth between January and April 2024 were designated as the observation group. The control group received routine breast feeding education, while the observation group received proxy online health information seeking based on TPB breast feeding guidance. Compared the breast feeding knowledge, self-efficacy, family support, as well as the electronic health literacy and breast feeding knowledge of the primary caregivers of two groups of postpartum women.Results:The final control group included 40 maternal and their primary caregivers, while the observation group included 47 each. The maternal age of the control group was (36.73 ± 4.36) years, while that of the observation group was (35.96 ± 3.24) years. The main caregivers for the control group of parturients were 5 males and 35 females, aged 61.00 (59.00, 62.00) years old. There were 8 males and 39 females in the observation group, aged 62.00 (59.00, 64.00) years. After 6 months of intervention, the scores of breast feeding knowledge, self-efficacy, and family support were 14.00(12.00, 16.00), 45.67 ± 9.49, 3.00(3.00, 4.00) in the intervention group, more than those in the control group 7.00(2.00, 10.75), 37.15 ± 8.12, 2.00(2.00, 3.00) points, the differences were statistically significant between the two groups ( Z=-6.55, -5.68, t=-4.45, all P<0.05); the primary caregivers' electronic health literacy and breast feeding knowledge scores were 31.45 ± 4.92 and 14.00 (11.00, 16.00), respectively, higher than those of the control group family members 28.68 ± 4.46 and 4.50 (2.00, 9.75). The differences were statistically significant ( t=-3.38, Z=-7.19, both P<0.05). The pure breast feeding rate at 1 week, 3 months and 6 months postpartum were 70.2%(33/47), 63.8%(30/47), 59.6%(28/47) in the intervention group, more than those in the control group 47.5%(19/40), 37.5%(15/40), 27.5%(11/40), the differences were statistically significant between the two groups ( χ2=4.64, 6.00, 8.99, all P<0.05). Conclusions:Proxy online health information seeking based on TPB can effectively strengthen the health information searching ability of primary caregivers of rural maternal, and help rural maternal improve breastfeeding knowledge, self-efficacy and family support to promote exclusive breast feeding.

Objective:To construct the enteral nutrition nursing scheme of ICU patients with abdominal hypertension based on internal abdominal pressure classification, and provide reference for effectively preventing enteral nutrition intolerance of ICU patients with abdominal hypertension.Methods:According to the "6S" evidence pyramid model, searched from top to bottom for relevant literature on enteral nutrition support for ICU patients with abdominal hypertension in databases such as BMJ Best Practice, Cochrane Library, Guidelines International Network, Medlive, UpToDate, PubMed, Ovid, Web of Science, Embase, China National Knowledge Infrastructure, VIP, Wanfang Medicine, Chinese Biomedical Literature. Developed an enteral nutrition care plan for ICU patients with abdominal hypertension based on intra-abdominal pressure grading, with a search date from database establishment to January 25, 2023. The Delphi expert letter consultation method was used to conduct two rounds of letter consultation with 20 experts to solicit expert opinions and determine the intervention plan.Results:The age of 20 experts was (43.75 ± 5.28) years old, with a working experience of (22.00 ± 6.98) years. The effective recovery rates of the two rounds of Delphi expert correspondence questionnaires were 100%(20/20), the expert judgment basis coefficients were 0.945 and 0.970, the familiarity coefficients were 0.865 and 0.895, and the authority coefficients were 0.905 and 0.932, respectively. Kendall coordination coefficient of importance of the first, second and third level items in the two rounds of expert correspondence were 0.100, 0.093, 0.098 and 0.200, 0.165, 0.119. The Kendall coordination coefficients of operability for the first, second and third level items were 0.117, 0.130, 0.115 and 0.200, 0.184, 0.154, respectively. Finally, an enteral nutrition nursing scheme for patients with abdominal hypertension in ICU was formed, which included 5 primary items, 30 secondary items and 51 tertiary items.Conclusions:The Delphi method in this study has a high degree of authority and enthusiasm of experts, and a good degree of coordination of expert opinions. The established enteral nutrition nursing scheme for ICU patients with abdominal hypertension based on intra-abdominal pressure classification is reliable and scientific, and can provide reference for clinical nursing practice of enteral nutrition for ICU patients with abdominal hypertension.

[Objective]To explore the expression of transcription factor KLF16 in nonalcoholic fatty liver disease(NAFLD)and its effect on lipid metabolism.[Methods]An animal model of NAFLD was constructed in mice induced by a high-fat diet.The mice were divided into normal diet group(ND)and high fat diet group(HFD).NAFLD cell model was constructed by primary mouse liver cells induced by oleic acid.The cells were divided into control group(Control group)and oleic acid induction group(OA group).Real-time fluorescence quantitative PCR(RT-qPCR)and Western blot were used to detect KLF16 expression in NAFLD animal and cell models.In vitro and in vivo models of KLF16 knockdown were constructed by injection of adeno-associated virus(AAV)into mouse tail veins and transient transfection of cell siRNA.Hematoxylin-eosin staining(HE)and other methods were used to detect changes in lipid deposition in NAFLD models be-fore and after KLF16 knockout.RT-qPCR was used to detect the expression of key genes of lipid metabolism in both cellu-lar and animal NAFLD models before and after KLF16 knockdown.Western blot assay was used to detect the expression of endoplasmic reticulum stress protein in NAFLD model before and after KLF16 knockdown.[Results]The expression level of KLF16 was up-regulated in HFD group and OA group,and lipid deposition was increased in OA group after KLF16 was depressed.There was no change in TC level in hepatocytes between groups(P>0.05),and TG level was increased in differ-ent degrees(P<0.05,P<0.001).At the same time,the change of KLF16 expression also caused the change of ER stress protein expression in OA group.[Conclusion]The transcription factor KLF16 may alleviate lipid deposition in nonalcoholic fatty liver disease by endoplasmic reticulum stress.

Objective:To study the urinary iodine levels of children in Jiangxi Province and provide a basis for prevention and treatment of iodine deficiency disorders and scientific iodine supplementation.Methods:From March to July in 2022, a systematic sampling method was used in 99 counties (cities, districts, abbreviated as counties) in Jiangxi Province. One township (street) was selected from each county in five directions: east, west, south, north and middle. One primary school was selected from each township (street), and 40 non boarding children aged 8 - 10 (half male and half female) were selected from each primary school. One random urine sample was collected to test urinary iodine, and the distribution of urinary iodine in different regions, genders, and ages were compared.Results:A total of 19 842 urine samples were collected from children, with a median urinary iodine level of 181.90 μg/L. The median urinary iodine levels of children in different cities ( H = 1 014.05, P < 0.001), genders ( Z = 6.44, P < 0.001) and ages groups ( H = 29.82, P < 0.001) were compared, and the differences were statistically significant. Conclusion:The urinary iodine level of children in Jiangxi Province is at an appropriate level, but the distribution of urinary iodine is uneven among different regions, genders, and ages, indicating that scientific and precise iodine supplementation is necessary for the prevention and treatment of iodine deficiency disorders.

Traumatic cataract is relatively common in clinical practice. Typically, non-metallic foreign bodies entering the eye do not cause intraocular reactions, manifesting only as traumatic cataract, while metal foreign bodies entering the eye are more likely to cause complications. Foreign bodies entering the eye can be detected through ophthalmic examination or found during cataract surgery. However, a very small number of patients may experience missed diagnosis in clinical practice. This article reported a case of traumatic cataract with disappearance of intraocular metal foreign body, presenting with a history and signs of ocular trauma and foreign body entry into the eye, but no foreign body was found before, during or after surgery. The reasons for the disappearance of the metal foreign body were also analyzed.

Objective:To analyze the quality control test results of urine fluoride laboratories in Jiangxi Province, and support reliable data for the monitoring and prevention of fluorosis.Methods:From 2019 to 2021, the Jiangxi provincial urine fluoride laboratories used the "Determination of Fluoride in Urine-Ion Selective Electrode Method" (WS/T 89-2015) to detect quality control samples. Origin 9 software was used to analyze the data, and Youden plots and deviation bar plots were produced. The results were evaluated based on the Z-score (qualified: │Z│ ≤2, basically qualified: 2 < │Z│ < 3, unqualified: │Z│ ≥3).Results:The qualified rate of quality control assessment results of urine fluoride laboratories in Jiangxi Province was 95.00% (38/40) . Most of urine fluoride laboratories had scores of │Z│ < 2, and two laboratories had scores │Z│≥3 in 2019 and 2020.Conclusion:The quality control assessment results of urine fluoride laboratories in Jiangxi Province are relatively satisfactory, but some laboratories still need to further improve their detection capabilities.

Objective:The programmed death receptor 1/programmed death ligand 1 (PD-1/PD-L1) pathway can negatively regulate the immune response of the body, and serum soluble PD-L1 (sPD-L1) can reflect the expression level of PD-L1. This study aims to compare the expressional differences of sPD-L1 in serum between patients with chronic hepatitis B (CHB) and C (CHC) and further explore the factors influencing the clinical cure of CHB.Methods:60 cases with CHB, 40 cases with CHC, and 60 healthy controls were selected. Serum levels of sPD-L1 were detected using an ELISA kit. The relationship between sPD-L1 levels and viral load, liver injury indicators, and others was analyzed in CHB and CHC patients. According to the distribution type of the data, a one-way ANOVA or Kruskal Wallis test as well as Pearson’s correlation or Spearman’s rank correlation analysis were performed. A difference of P<0.05 was considered statistically significant.Results:The serum sPD-L1 levels were significantly higher in CHB patients (414.6 ± 214.9) pg/ml than those in CHC patients (58.9 ± 122.1) pg/ml and the healthy control group (66.27 ± 24.43) pg/ml, and there was no statistically significant difference in serum sPD-L1 between CHC patients and the healthy control group. Further grouping and correlation analysis showed that the level of serum sPD-L1 was positively correlated with the content of HBsAg in CHB patients but not with HBV DNA, alanine transaminase, albumin, and other liver injury indicators. Additionally, there was no correlation between serum sPD-L1 levels, HCV RNA, and liver injury indicators in CHC patients.Conclusion:The serum sPD-L1 levels are significantly higher in CHB patients than those in the healthy control group and the CHC group, and there is a positive correlation between sPD-L1 levels and HBsAg. The persistent presence of HBsAg is an important mechanism for the activity of the PD-1/PD-L1 pathway, indicating that the activity of the PD-1/PD-L1 pathway may be an important factor that cannot be clinically cured in CHB as in CHC.
