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 nodakenin(Nod)in neuropathic pain(NP).Methods Differential expression genes in the primary somatsensory cortex(S1)of NP data and overlapping genes between the dataset and mitochondrial data were screened and analyzed.Overlapping gene interaction networks were overlapped and core genes were screened.A total of 27 mice were randomly divided into the sham operation group,the model group and the drug administration group(9 mice/group).The chronic compression injury model of sciatic nerve was constructed in the model group and the drug administration group.Nod 10 mg/kg was intraperitoneally injected into the drug administration group for 1 week.Changes of pain behavior and motor ability in mice were detected.HE staining and Nissl staining were used to detect effects of nerve injury and inflammation on brain tissue of S1 region of mice.The expression levels of interleukin-1β,early gene(c-Fos),panthenol-cytochrome c reductase complex III subunit(Uqcrq)and ubiquinone oxidoreductase subunit(Nduf)b5 in S1 brain region were analyzed by Western blot assay.Molecular docking was used to study the target of Nod.PC12 cells were divided into the control group,the IL-1β group(1 μmol/L IL-1β treatment)and the IL-1β+Nod group(1 μmol/L IL-1β+1 μmol/L Nod treatment),and mitochondrial membrane potential was detected in each group.Results In the NP dataset GSE180627,S1 brain region contained 293 differentially expressed genes,and the mitochondrial data contained 1 082 genes.There were 34 overlapping genes,and genes related to oxidative phosphorylation and electron transport chain were enriched.The protein interaction network showed that core genes included electron transport chain related proteins Ndufb5,Uqcrq,Ndufs8,Ndufa7,Ndufa3,Cox6b1 and Mrps33.Compared with the model group,the mechanical foot shrinkage threshold,thermal foot shrinkage reflex latency and rod rotation residence time of mice were increased in the drug administration group,the number of inflammatory infiltrating cells in S1 tissue and the number of Nislet bodies in neurons,expression levels of c-Fos and IL-1β in neurons were decreased,and expression levels of Uqcrq and Ndufb5 were increased(P＜0.05).Molecular docking showed that Nod could bind Uqcrq and Ndufb5.Compared with the IL-1β group,the fluorescence signal of mitochondrial membrane potential was enhanced in the IL-1β+Nod group(P＜0.05).Conclusion Nodakenin can improve pain behavior in mice,and its mechanism involves ameliorating mitochondrial damage in S1.

Objective·To explore the effect of continuous nursing based on EMS[environment management(E),medicine direction(M)and self monitoring(S)]management mode on the preschool children with asthmatic diseases.Methods·A total of 67 children aged 0 to 6 years with asthmatic diseases admitted to the Department of Respiratory Medicine,Shanghai Children's Hospital,Shanghai Jiao Tong University School of Medicine from December 2019 to November 2020 were selected and divided into observation group(33 cases)and control group(34 cases)according to the random number table method,with 3 cases lost,and finally 32 cases in each group.The observation group received continuous nursing care based on EMS management mode,while the control group received routine care and discharge follow-up through the telephone.The children in the two groups were followed up at 1,3,and 6 months after discharge to evaluate the results of Test for Respiratory and Asthma Control in Kids(TRACK)and wheezing recurrence;Medication Adherence Report Scale for Asthma(MARS-A)and Nursing Job Satisfaction Questionnaire were used to evaluate medication adherence and nursing job satisfaction 6 months after discharge.Results·There was no significant difference in demographic characteristics and clinical baseline characteristics between the two groups.Repeated measures analysis of variance showed that effects of time,groups and the interaction of groups×time on the total score of TRACK were statistically significant.The total scores of TRACK in the observation group were significantly higher than those in the control group at 1,3,and 6 months after discharge(P=0.000).The total scores of TRACK in the two groups gradually increased with time(P=0.000).The recurrence rates of wheezing in the observation group were 25.0%,18.7%,and 9.4%at 1,3,and 6 months after discharge,which were significantly lower than those in the control group(50.0%,43.7%,and 31.3%,respectively,P<0.05).Generalized estimating equation analysis showed that there was a statistically significant difference between the two groups(P=0.013),and the intervention effect of the observation group was better than that of the control group(OR=0.292).The MARS-A score of the observation group was 4.519±0.395 at 6 months after discharge,which was significantly higher than that of the control group(3.994±0.739,P=0.001).The nursing job satisfaction of the observation group was significantly higher than that of the control group(P=0.000).There was a moderate positive correlation between the MARS-A score and the nursing job satisfaction(r=0.389,P=0.001).Conclusion·Continuous nursing based on EMS management mode can significantly improve the medication compliance and wheezing control level of the preschool children with asthmatic diseases,significantly reduce the recurrence rate of wheezing,and improve the nursing satisfaction.

Objective:To investigate the influence of trimethylamine N-oxide(TMAO)on the development of early neurological deterioration(END)in diabetic patients with acute ischemic stroke.Methods:In this cross-sectional study, 108 type 2 diabetes patients with acute ischemic stroke treated at the Department of Neurology in the Affiliated Wuxi People’s Hospital of Nanjing Medical University between October 2019 and November 2020 were consecutively recruited.END was defined as an increase in the National Institutes of Health Stroke Scale(NIHSS)≥ 2 points and exclusion of intracranial hemorrhage or bleeding transformation in cranial imaging evaluation within 5 days of initial deterioration of neurological dysfunction.The patients were divided into 2 groups, an END(n=36)group and a non-END group(n=72). Fasting plasma TMAO was measured using isotope dilution liquid chromatography coupled to tandem mass spectrometry.Results:Of the 108 patients, 36(33.3%)were diagnosed with END, and their plasma TMAO levels were significantly higher compared with patients without END( Z=-3.500, P<0.001). For prediction of END, the area under the ROC curve for plasma TMAO levels was 0.707(95% CI: 0.603-0.811, P<0.001). The frequencies of END in subjects grouped via tertiles of TMAO were 22.2%, 19.4% and 58.3%, respectively, with significant differences between the 3 groups( χ2=14.979, P=0.001). Univariate analysis showed that elevated TMAO( OR=1.160, 95% CI: 1.050-1.282, P=0.004)was associated with END.A multivariate logistic regression model further confirmed the association between TMAO and END( OR=1.145, 95% CI: 1.033-1.269, P=0.010). Conclusions:Increased plasma TMAO levels are associated with END in diabetic patients with acute ischemic stroke.

RNAs are involved in the crucial processes of disease progression and have emerged as powerful therapeutic targets and diagnostic biomarkers. However, efficient delivery of therapeutic RNA to the targeted location and precise detection of RNA markers remains challenging. Recently, more and more attention has been paid to applying nucleic acid nanoassemblies in diagnosing and treating. Due to the flexibility and deformability of nucleic acids, the nanoassemblies could be fabricated with different shapes and structures. With hybridization, nucleic acid nanoassemblies, including DNA and RNA nanostructures, can be applied to enhance RNA therapeutics and diagnosis. This review briefly introduces the construction and properties of different nucleic acid nanoassemblies and their applications for RNA therapy and diagnosis and makes further prospects for their development.
