Objective To investigate the correlation between hemoglobin A1c(HbA1c)levels and excessive daytime sleepiness(EDS)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 132 T2DM patients and 40 healthy people(NC group)who were treated in the outpatient department of Nanjing Meishan Hospital from December 2020 to December 2022 were selected.General clinical data of the subjects were collected,and their Epworth sleepiness scale(ESS)scores,Pittsburgh sleep quality index(PSQI),and apnea-hypopnea index(AHI)were measured.Based on ESS scores,T2DM patients were divided into simple T2DM group(ESS score<9,n=99)and EDS group(ESS score≥9,n=33)according to ESS score.The baseline data were compared for each group.Spearman correlation analysis and multivariate logistic regression model were used to evaluate the correlation between HbA1c levels and EDS.The receiver operating characteristic(ROC)curve was used to calculate the area under the curve(AUC)to evaluate the predictive value of HbA1c levels for EDS.Results HbA1c,fasting plasma glucose,AHI index and PSQI score in EDS group were higher than those in T2DM and NC group(P<0.05).Spearman correlation analysis showed that ESS score was positively correlated with HbA1c in T2DM patients(P<0.05).Multivariate logistic regression analysis revealed that elevated HbA1c levels emerged as a significant and independent risk factor for the onset of EDS.The ROC curve indicated that the AUC of HbA1c for predicting EDS was 0.736.Conclusions There is an independent positive correlation between HbA1c levels and EDS in T2DM patients,which provides clues for early identification and treatment of EDS in clinical practice.

ObjectiveTo investigate the bacterial diversity in the rhizosphere soil and phyllosphere of Angelica sinensis and examine the effects of foliar applications of a composite bacterial agent，salicylic acid，and coronatine on the bacterial diversity，disease incidence，and plant yield，thus providing a theoretical basis and guidance for the artificial construction of functional minimal communities and the regulation of rhizosphere through foliar treatments. MethodsUnder continuous cropping conditions in the field，foliar applications of a composite bacterial agent，salicylic acid，coronatine，and sterile water were conducted. The 100-plant weight was measured via the conventional method，and the incidence of diseases was recorded. The microbial community composition，diversity，and inter-group differences in the phyllosphere and rhizosphere soil of A. sinensis were analyzed by 16S high-throughput sequencing，and the potential microbial functions were predicted. ResultsCompared with the blank control，foliar applications of salicylic acid and coronatine both significantly reduced the yield and root rot incidence of A. sinensis. The foliar application of salicylic acid decreased the content of ferulic acid and increased that of ligustilide. The foliar application of coronatine increased the content of both ferulic acid and ligustilide. The microbial communities and functions in the phyllosphere and rhizosphere soil were significantly different. The phyllosphere had lower microbial diversity，with all bacteria being Gram-negative，mainly Cyanobacteria and Proteobacteria with limited functions. The rhizosphere soil had higher microbial diversity，harboring dominant phyla including Proteobacteria，Actinobacteria，Acidobacteria，and Bacteroidetes with rich functions. All foliar treatments regulated the microbial community in the rhizosphere soil，with a more significant effect on the microbial community in the rhizosphere soil than that in the phyllosphere. The coronatine treatment significantly reduced the abundance of Proteobacteria and nitrate-reducing and aromatic compound-degrading microorganisms in the rhizosphere soil，thus affecting nutrient cycling and autotoxic substance degradation and leading to a yield reduction. Compared with the salicylic acid treatment，the coronatine treatment significantly increased the abundance of Bacillus and Streptomyces in the rhizosphere soil，demonstrating enhanced disease control efficacy. ConclusionFoliar application of coronatine and salicylic acid can significantly regulate the composition and function of bacterial communities in the rhizosphere soil，thereby reducing the disease incidence and the plant yield.

The liver performs multiple life-sustaining functions. Hepatic diseases, including hepatitis, cirrhosis, and hepatoma, pose significant health and economic burdens globally. Along with the advances in nanotechnology, mesoporous silica nanoparticles (MSNs) exhibiting diversiform size and shape, distinct morphological properties, and favorable physico-chemical features have become an ideal choice for drug delivery systems and inspire alternative thinking for the management of hepatic diseases. Initially, we introduce the physiological structure of the liver and highlight its intrinsic cell types and correlative functions. Next, we detail the synthesis methods and physicochemical properties of MSNs and their capacity for controlled drug loading and release. Particularly, we discuss the interactions between liver and MSNs with respect to the passive targeting mechanisms of MSNs within the liver by adjusting their particle size, pore diameter, surface charge, hydrophobicity/hydrophilicity, and surface functionalization. Subsequently, we emphasize the role of MSNs in regulating liver pathophysiology, exploring their value in addressing liver pathological states, such as tumors and inflammation, combined with multi-functional designs and intelligent modes to enhance drug targeting and minimize side effects. Lastly, we put forward the problems, challenges, opportunities, as well as clinical translational issues faced by MSNs in the management of liver diseases.

Objective To analyze the effects of different gender,gestational age,birth weight and blood collection date on the value of 17-hydroxyprogesterone(17-OHP)in neonatal screening for congenital adrenal hyperplasia(CAH)and to develop a positive cut-off for CAH screening that is appropriate for the laboratory itself.Methods Time-resolved fluorescence immunoassay was used to detect 17-OHP concentration,and Mann-Whitney U test and Kruskal-Wallis H test were used to compare 17-OHP concentration of newborns with the different gender,birth weight,gestational age and blood collection age.The comparison of rates was conducted using the multi-set rate chi-square test and Fisher's exact probability method.The relationship between the clinical features and 17-OHP concentration was analyzed by multiple linear regression,and the cut-off value of 17-OHP screening was 99.5％percentile.Results The 17-OHP concentration of male neonates was higher than that of female neonates,and the difference was statistically significant(Z=-17.768,P<0.05).The 17-OHP concentration of neonates in groups with different gestational age,different birth weight,and different blood collection days were compared respectively,and the difference was statistically significant(χ2=5 235.187、3 682.665、493.414 respectively,P=0.00).Further pair comparison showed that there were statistically significant differences in 17-OHP concentration of neonates at different gestational weeks,gestational age and blood collection days(P<0.05),except that age of blood collection≥3 and<4 days and≥4 and<7 days(Z=-0.950,P=0.342).Neonatal 17-OHP concentration decreased with the gestational age and birth weight increase.There were statistically significant differences in the initial screening positive rate and screening positive rate of 17-OHP among different gestational ages and different birth weights groups(P<0.05),and they decreased with the increase of gestational age,birth weight and age at the time of blood collection.The results of multiple linear regression showed that 17-OHP concentration was related to the several factors,including the gestational age,birth weight,age of blood collection and gender in descending order.Conclusion The effects of various factors on the concentration of 17-OHP in neonatal peripheral blood should be comprehensively considered.The cut-off value of 17-OHP for CAH screening in the Screening Center for Neonatal Genetic Metabolic Diseases in the First Affiliated Hospital of Kunming Medical University is modified to≥14.00 nmol/L for full-term neonates of normal weight and≥36.00 nmol/L for premature or/and low-weight neonates so as to improve the specificity of neonatal CAH screening and reduce the false positives.

Objective To investigate the impact of hemoglobin(Hb)level on the risk of all-cause mortality in elderly patients with stable coronary artery disease(SCAD)treated by percutaneous coronary intervention(PCI).Methods A retrospective cohort study was conducted on 195 elderly SCAD patients treated by PCI in our hospital from June 2016 to December 2017,a total of 180 case were followed up.They were divided into four groups based on quartiles of Hb levels:Q1 group[≤122(108.28±12.53)g/L,n=47],Q2 group[122＜Hb≤137(130.07±4.33)g/L,n=43],Q3 group[137＜Hb≤148(142.67±3.10)g/L,n=46],and Q4 group[＞148(158.36±8.50)g/L,n=44].Their clinical data were collected and compared among the groups.All patients were followed up,with all-cause mortality as endpoint.Cox regression analysis was used to evaluate the impact of Hb level on all-cause mortality in elderly SCAD patients treated by PCI.Results For the 180 patients with complete follow-up,the median follow-up time was 703(415,1121)d,and the incidence of all-cause mortality was 10.00％(totally 18 deaths).And the incidence was 25.50％(12 deaths),7.00％(3 death),4.30％(2 deaths)and 2.30％(1 death)in Q1,Q2,Q3,and Q4 groups,respectively,with statistically significant differences(P＜0.01).Univariate Cox regression analysis showed age was a risk factor for all-cause death(P＜0.01),while Hb level,BMI,smoking history,dyslipidemia,and aspirin use were a risk facotr for all-cause death(P＜0.05,P＜0.01).Further multivariate Cox regression analysis revealed Hb level was a risk facotr for all-cause death(HR=0.96,95％CI:0.93-0.99,P＜0.01).The risk of all-cause mortality was 3.68 times higher in the Q1 group than the Q2 group(HR=3.68,95％CI:1.01-13.45,P＜0.05),and there was no correlation in the incidence between the Q3 and Q4 groups(P＞0.05).Conclusion Low Hb level is an independent predictor for all-cause mortality in elderly SCAD pa-tients after PCI.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective:To investigate the prognostic significance of anemia in elderly patients with stable coronary artery disease treated by percutaneous coronary intervention(PCI).Methods:In this retrospective cohort study, 180 patients with stable coronary artery disease aged ≥60 years undergone percutaneous coronary intervention and with complete clinical data, admitted to Nanjing Meishan Hospital between June 2016 and December 2017, were selected.Baseline clinical data of the patients were collected, including hemoglobin, C-reactive protein, lipids, fasting glucose, glycated hemoglobin, blood creatinine, and left ventricular ejection fraction on cardiac color ultrasound.The endpoints of the follow-up included major adverse cardiac events(MACE), such as all-cause death, non-fatal myocardial infarction, and non-fatal stroke.According to the hemoglobin level, participants were divided into an anemia group(n=32)and a non-anemia group(n=148). Clinical data of the two groups were compared, and the Kaplan-Meier method and multivariate analysis with the Cox regression method were used to evaluate the effect of anemia on the occurrence of MACE in elderly patients with stable coronary artery disease treated by PCI.Results:The median duration of the follow-up of the 180 patients was 702.5 days and MACE occurred in 27(15.0%). Compared with the non-anemia group, the anemia group had a higher age, C-reactive protein level and MACE ratio, lower levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol and the glomerular filtration rate, and higher proportions of patients with smoking history and patients with dyslipidemia( P<0.05). Kaplan-Meier curves suggested that the incidence of MACE in the anemia group was higher than that in the non-anemia group[37.5%(12/32) vs.10.1%(15/148), P<0.05]. Multivariate analysis with the Cox regression method showed that the risk of MACE in the anemia group was 2.91 times higher than that in the non-anemia group( HR=2.91, 95% CI: 1.13-7.48, P<0.05). Conclusions:Anemia is an independent predictor of MACE in elderly patients with stable coronary artery disease after PCI.

Mass spectrometry imaging (MSI), a label-free molecular imaging technique, has been applied widely in the spatial localization of small molecule metabolites, lipids, peptides, and proteins, with its unique advantage of high spatial resolving power compared to traditional liquid chromatography-mass spectrometry (LC-MS).With the nonstop advancement of its achievable sensitivity and spatial resolution, MSI technique has been providing novel perspectives into the preclinical studies of drugs, such as in vivo localization of drugs and their metabolites, visualization of drug metabolism, and drug delivery tracking.This review introduces the basics of MSI techniques, including basic principles, key features, technical advantages, and limitations, with particular highlight of the recent applications of MSI in drug efficacy and safety evaluation, drug distribution research, drug delivery research, and analysis of Chinese medicine from recent publications, aiming to promote the utilization and further expansion of MSI in the research and development of drugs.

Objective To investigate the clinical data of a family diagnosed with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy(CADASIL) with isolated vertigo as the initial symptom. Methods The clinical manifestations,imaging findings,pathology,genetic testing results,and CADASIL scale score of a patient with CADASIL were summarized,and a family investigation was conducted. Results The proband of this case experienced recurrent isolated vertigo and gradually developed emotional disorder. Cranial magnetic resonance imaging(MRI) FLAIR revealed extensive subcortical white matter degeneration in both hemispheres,characteristic abnormal hyperintensity in bilateral temporal poles and external capsules,abnormal hyperintensity in bilateral brainstems,and multiple lacunar infarctions in bilateral corona radiata and basal ganglia. The score of CADASIL scale was 16 points. Skin biopsy showed the deposition of electron-dense granular osmiophilic material around vascular smooth muscle. Genetic testing identified a heterozygous mutation of c. 1163G>A(p. C388Y) in the NOTCH3 gene. The elder sister of the proband also had isolated vertigo and was found to have the same mutation by genetic testing. The father and uncle of the proband died of cerebral infarction,while the aunt of the proband suffered from severe dementia,and all of them had experienced dizziness in the early stage. Conclusion CADASIL has clinical heterogeneity and can manifest as isolated vertigo. Abnormal signals in temporal poles and external capsules on cranial MRI have an important value in the diagnosis of this disease,while pathological examination is required to make a confirmed diagnosis,and genetic testing can further clarify the diagnosis and perform screening of other family members.
