Objective To compare the influence between self-monitoring of blood gluocose(SMBG)combined with digital diabetes management and traditional management mode on the related clinical indexes in the patients with type 2 diabetes mellitus(T2DM).Methods A total of 100 patients with T2DM treated in the endocrinology and metabolism outpatient department of this hospital from January 2022 to June 2022 and meeting the inclusion criteria of this study were successively included.They were divided into the experimental group and control group.The experimental group was managed by SMBG combined with digital diabetes man-agement mode,while the control group adopted the traditional management mode,the outpatient clinic follow up once a month.After 6 months of follow-up,fasting blood glucose,glycosylated hemoglobin(HbA1c),low density lipoprotein cholesterol(LDL-C)and urinary microalbumin/creatinine ratio(UACR)were compared between the two groups.Results The FBG,HbA1c,LDL-C,and UACR of the experimental group decreased after intervention when compared with baseline.Compared with the control group,the FBG[8.7(7.7,9.2)mmol/L vs.10.8(8.8,12.7)mmol/L,Z=-4.660,P＜0.001],HbA1c[6.3％(5.3,7.8)％vs.8.5％(7.2,10.0)％,Z=-5.130,P＜0.001],LDL-C[2.6(1.8,3.1)mmol/L vs.3.3(2.6,4.0)mmol/L,Z=-4.112,P＜0.001],UACR[16.1(3.5,46.5)mg/g vs.58.4(11.9,108.0)mg/g,Z=-2.220,P=0.026]for patients in the expriemental group after intervention were significantly decreased.Conclusion SMBG combined with digital diabetes management model can significantly improve the clinical indicators of patients.

Objective To explore the therapeutic mechanism of Modified Lugen Formula(Phragmitis Rhizoma,Cicadae Periostracum,Batryticatus Bombyx,Lonicerae Japonicae Flos,Glycyrrhiza,Menthae Haplocalycis Herba,Notopterygii Rhizoma et Radix,Puerariae Lobatae Radix,Bupleuri Radix)in treating influenza from the virus-host interaction interface.Methods The phytocompounds were first collected from the HERB database,and then potential active compounds were screened out by Lipinski's rules of five.The targets of active compounds were further predicted through the SwissTargetPrediction platform.Differentially expressed genes(DEGs)were determined from the human H1N1 influenza dataset GSE90732 available in the Gene Expression Omnibus database(GEO).H1N1-Homo sapiens-related protein-protein interactions(PPIs)were gathered from the Pathogen-Host Interaction Search Tool(PHISTO).The above mentioned bioinformatic datasets were integrated.Then a PPI network and a Formula-virus-host interaction network were constructed using Cytoscape.Functional enrichment analyses were performed by using R software.Finally,molecular docking was carried out to evaluate the binding activities between the key compounds and targets.Results A total of 1 252 active compounds,1 415 targets,951 influenza-related DEGs,and 10 142 H1N1-Homo sapiens-related PPIs were obtained.There were 72 intersection targets between the Modified Lugen Formula and influenza.Functional enrichment analyses showed that these targets are closely related to host defense and programmed cell death.The network topological analysis showed that active compounds in the Modified Lugen Formula,such as oleanolic acid,γ-undecalactone,and longispinogenin,regulate viral proteins M2,NA,NS1,and HA and/or the host factors HSP90AA1,NRAS,and ITGB1,thus exert therapeutic effect.Molecular docking results confirmed that these compounds had a good binding ability with the targets.Conclusion Multiple active ingredients in Modified Lugen Formula directly target influenza virus proteins and/or host factors,thereby play an anti-influenza role in multiple dimensions,including inhibiting virus replication,regulating host defense and cell death.This study provides a theoretical basis for further experimental analysis of the action mechanism of the Modified Lugen Formula in treating influenza.

To evaluate the effect of bronchoalveolar lavage (BAL) on the clinical prognosis of children with macrolide drug-resistant Mycoplasma pneumoniae pneumonia (MRMPP) in a retrospective cohort study based on propensity score matching (PSM).A retrospective cohort study based on propensity score matching retrospectively collected the clinical data of hospitalized patients diagnosed with mycoplasma macrolide drug-resistant pneumonia (MRMPP) in Respiratory Department of Hunan Children′s Hospital from January 2020 to August 2023. According to whether bronchoalveolar lavage (BAL) was performed during hospitalization, the children were divided into BAL group and non-BAL group, and the baseline information of the two groups was matched by propensity scores, and the clinical prognosis was compared. A total of 302 children were screened, and 150 cases were successfully matched, including 59 cases in the BAL group and 91 cases in the non-BAL group. The results showed that the differences between the non-BAL group and the BAL group before PSM( P<0.05) were significantly different in age [(4.60±2.97)years vs (5.41±3.02) years, t=-2.273, P=0.024], shortness of breath (9.4% vs 22.5%, χ 2=9.864, P=0.002), and radiographic manifestations [lung interstitial changes (29.8% vs 15.3%, χ 2=8.009, P=0.005), lung consolidation (17.3% vs 55.9%, χ 2=48.457, P<0.001), spotted flaky infiltrates (52.4% vs 27.9%, χ 2=17.056, P<0.001)], bacterial infection (3.2% vs 9.2%, χ 2=4.845, P=0.028), duration of azithromycin or doxycycline use [4(2, 5) days vs 5(3, 6) days, Z=-2.374, P=0.018], White Blood Cell Count at admission [7.94 (6.25, 10.34)×10 9/L vs 7.21 (5.65, 9.01)×10 9/L, Z=-2.445, P=0.014], D Dimer [0.58 (0.44, 0.83) μg/ml vs 0.80 (0.52, 1.12) μg/ml, Z=-3.154, P=0.002], but there was no significant difference between the two groups in the above indexes after PSM ( P>0.05). The duration of hospitalization, cough relief, disappearance of rales and fever in the BAL group was shortened in the BAL group compared with that in the non-BAL group [5 (4, 7) days vs 7 (5, 8) days, Z=-2.373, P=0.018], and the difference was statistically significant ( P<0.05). Linear regression analysis of PSM cohort study showed that BAL was negatively correlated with fever time (β=-4.369, 95% CI:-8.600--0.138, P<0.05). In conclusion, BAL can shorten the fever time of MRMPP, and early BAL in addition to conventional treatment has a positive effect on the prognosis of children.

Objective:To explore the optimization of the standardized assessment tool for clinical diagnosis of Chinese developmental dyslexia (DD).Methods:A cross-sectional study was conducted from May to December 2023, in which 130 primary school children in grades 1 to 3 with clinical signs of literacy lag and positive screening results on the screening scales were recruited from the outpatient clinic of Child Health Care Medical Division, Shanghai Children′s Hospital, Shanghai Jiao Tong University School of Medicine. Chinese dyslexia screening behavior checklist for primary students (CDSBC) was used as the screening scales, and supplemented by dyslexia checklist for Chinese children. Referring to the standard procedure of the"expert advice on diagnosis and intervention of Chinese developmental dyslexia", the developmental dyslexia scale for standard mandarin (DDSSM) was used to evaluate the children′s literacy-related cognitive abilities and conduct the diagnostic assessment, and divided the children into learning backward group and the DD group. The t-test and χ2 test were used to compare the differences in the distribution of intelligence, literacy and attention deficit hyperactivity disorder between the two groups. Spearman′s correlation was used to analyze the correlation between the scores for each cognitive ability in the DDSSM and the CDSBC. Results:Of the 130 children, 90 were male, aged (8.3±1.0) years; 40 were female, aged (8.1±0.9) years. A final diagnosis of DD was made in 59 cases, of which 41 were males. There was no statistically significant difference in operational intelligence quotient (101±15 vs.100±15, t=0.53, P>0.05) and statistically significant difference in literacy of DDSSM (32±5 vs.21±4, t=11.56, P<0.001) between the learning backward group and the DD group. Eighteen cases (25.4%) of the learning backward group were children with attention deficit subtype attention deficit hyperactivity disorder (ADHD-I), and 16 cases (27.1%) in DD group, the difference in incidence between the two groups was not statistically significant ( χ2=0.05, P>0.05). There were correlations between the DDSSM (for oral vocabulary, morphological awareness and orthographic awareness) and the CDSBC total score ( r=-0.42, -0.32, -0.35, all P<0.01), but the correlations for visuospatial perception and rapid automatized naming with CDSBC total score were not statistically significant ( r=-0.09 and -0.20,both P>0.05). Conclusion:For literacy-related cognitive abilities, screening scales CDSBC are not sufficiently useful for assessment, so the introduction of standardized assessment tools DDSSM is an optimization of the clinical diagnosis of Chinese DD, which is crucial for achieving accurate diagnosis and intervention.

Cervical cancer is the fourth most common cancer among women worldwide,and several screen-ing methods are currently available,with DNA testing for human papillomavirus(HPV)considered to be the most effective technique compared to other screening methods.However,due to the lack of organized screen-ing programs and facilities in developing countries,effective screening of cervical cancer is difficult to imple-ment,thereby delaying disease prediction and contributing to the high incidence of cervical cancer.In order to improve cervical cancer screening coverage in women,a simple,time-saving and non-invasive screening method is needed.At present,more and more evidence supports the validity and practicability of self-sampling as an al-ternative method for primary HPV screening.In this paper,we reviewed the application progress of HPV self-sampling in cervical cancer screening from three aspects:vaginal self-collection,initial urine sample self-collec-tion and menstrual blood sample self-collection.

Objective:To establish a risk prediction model for prolonged mechanical ventilation in adult heart transplant recipients.Methods:This study used structured language to query hospital electronic medical record systems. From January 2004 to December 2021, 957 adult recipients undergoing cardiac transplantation at Fuwai Hospital of the Chinese Academy of Medical Sciences were selected as the study subject using a convenience sampling. This study collected basic information, past history, preoperative blood creatinine, preoperative total bilirubin, preoperative ventilation assistance, and intraoperative donor heart cold ischemia time. The enrolled patients were divided into a training group ( n=717) and a validation group ( n=240) in a ratio of 3∶1. Based on the training group data, a risk prediction model was constructed using two-way stepwise Logistic regression. The prediction performance of the model was evaluated using the area under the receiver operating characteristic (ROC) curve, sensitivity and specificity based on the validation group data. Results:A total of 957 adult heart transplant recipients were included, and 18.39% (176/957) of them experienced prolonged mechanical ventilation (>24 hours) after surgery. Based on the model established by the training group data, 7 independent risk factors for prolonged mechanical ventilation after surgery were clarified, including age ≥ 60 years old ( OR=1.820), history of blood transfusion ( OR=5.237), previous cardiac surgery ( OR=2.826), preoperative total bilirubin≥ 34.2 μmol/L ( OR=1.861), preoperative ventilator assistance ( OR=9.421), preoperative intra-aortic balloon pump assistance ( OR=1.826), intraoperative donor heart cold ischemia time≥ 360 min ( OR=2.093) ( P<0.05). The area under the curve of the model was 0.676 (95% confidence interval was 0.581 to 0.770), with a sensitivity of 0.500, and a specificity of 0.796. Conclusions:Based on the data of adult heart transplant recipients from a single center, this study established a relatively simple and objective risk prediction model that can predict the prolonged mechanical ventilation in adult heart transplant recipients, and has good clinical value.

T cell infiltration and proliferation in tumor tissues are the main factors that significantly affect the therapeutic outcomes of cancer immunotherapy. Emerging evidence has shown that interferon-gamma (IFNγ) could enhance CXCL9 secretion from macrophages to recruit T cells, but Siglec15 expressed on TAMs can attenuate T cell proliferation. Therefore, targeted regulation of macrophage function could be a promising strategy to enhance cancer immunotherapy via concurrently promoting the infiltration and proliferation of T cells in tumor tissues. We herein developed reduction-responsive nanoparticles (NPs) made with poly (disulfide amide) (PDSA) and lipid-poly (ethylene glycol) (lipid-PEG) for systemic delivery of Siglec15 siRNA (siSiglec15) and IFNγ for enhanced cancer immunotherapy. After intravenous administration, these cargo-loaded could highly accumulate in the tumor tissues and be efficiently internalized by tumor-associated macrophages (TAMs). With the highly concentrated glutathione (GSH) in the cytoplasm to destroy the nanostructure, the loaded IFNγ and siSiglec15 could be rapidly released, which could respectively repolarize macrophage phenotype to enhance CXCL9 secretion for T cell infiltration and silence Siglec15 expression to promote T cell proliferation, leading to significant inhibition of hepatocellular carcinoma (HCC) growth when combining with the immune checkpoint inhibitor. The strategy developed herein could be used as an effective tool to enhance cancer immunotherapy.

Objective: To analyze the expression and clinical prognostic significance of nuclear Dbf2-related kinase 1 ( NDR1 ) in hepatocellular carcinoma ，and to investigate the biological function and regulatory mechanism of NDR1 in hepatocellular carcinoma cells． Methods: ENCORI database was used to analyze the correlation of NDR1 and c-Myc．Cycloheximide ( CHX) experiment analyzed the relationship between NDR1 and c-Myc protein stability．The expression levels of NDR1 in liver cancer tissues and normal tissues and its relationship with the survival rate of liver cancer patients were analyzed using the ENCORI database．MYC-NDR1 eukaryotic expression vector was constructed，transfected with hepatocellular carcinoma HepG2 cells，and its expression was verified by protein immuno blotting (Western blot) ; cell proliferation and migration ability were detected by CCK-8 assay，cell clone formation assay and scratch assay，respectively．The correlation between NDR1 and c-Myc expression was analyzed using the ENCORI database，and the relationship between NDR1 and c-Myc protein was investigated using a protein synthesis inhibitor CHX dosing assay. Results: The results of the ENCORI database showed that the expression of NDR1 in liver cancer tissues was higher than that in normal tissues and the overall survival rate of patients with high NDR1 expression was lower than that of patients with low NDR1 expression，and the difference was statistically significant (P＜0. 001) ．The results of the CCK-8 assay showed that the MYC-NDR1 group grew faster than the empty vector group (P＜0. 001) ．The clone formation assay showed that the number of clones in the MYC-NDR1 group was higher than that in the empty vector group (P＜0. 001) ．The cell scratch assay showed that the mean migration distance in the MYC-NDR1 group was greater than that in the empty vector group (P＜0. 001) ．ENCORI database analysis showed that NDR1 correlated with c-Myc expression (R = 0. 184，P＜0. 001) ; CHX dosing assay showed that the reduction of c-Myc protein in the MYC-NDR1 group was lower than that in the empty vector group during the same time． Conclusion NDR1 is highly expressed in hepatocellular carcinoma tissues，closely correlated with poor prognosis of hepatocellular carcinoma patients ，and positively correlated with the expression of c-Myc gene. The study successfully constructes MYC-NDR1 eukaryotic expression vector ，and the expression product MYC- NDR1 can increase the stability of c-Myc protein and promote the proliferation and migration of human hepatocellu- lar carcinoma cells.

Malnutrition and dehydration are prevalent in the elderly poplulation, and obesity is also a growing problem, which pose a serious challenge to the nutritional management in geriatrics. In order to better guide clinical practice, the European Society for Clinical Nutrition and Metabolism (ESPEN) published the practical guideline on clinical nutrition and hydration in geria-trics on March 5, 2022. This guideline provides 82 recommendations on clinical nutrition and hydration in geriatrics based on clinical practicability, covering basic problems and general prin-ciples, prevention and treatment of malnutrition/nutri-tional risk, prevention and treatment of specific diseases, as well as prevention and treatment of obesity, along with flow-charts, hoping to be convenient for doctors, nutritionists and nurses to use in clinical practice.
