BACKGROUND: The global rise in diabetes prevalence is a pressing concern. Despite initiatives like "The Healthy Beijing Action 2020-2030" advocating for increased awareness, treatment, and control, the specific situation in Beijing remains unexplored. This study aimed to analyze the trends in diabetes prevalence, awareness, treatment, and control among Beijing adults. METHODS: Through a stratified multistage probability cluster sampling method, a series of representative cross-sectional surveys were conducted in Beijing from 2005 to 2022, targeting adults aged 18-79 years. A face-to-face questionnaire, along with body measurements and laboratory tests, were administered to 111,943 participants. Data from all survey were age- and/or gender-standardized based on the 2020 Beijing census population. Annual percentage rate change (APC) or average annual percentage rate change (AAPC) was calculated to determine prevalence trends over time. Complex sampling logistic regression models were employed to explore the relationship between various characteristics and diabetes. RESULTS: From 2005 to 2022, the total prevalence of diabetes among Beijing adults aged 18-79 years increased from 9.6% (95% CI: 8.8-10.4%) to 13.9% (95% CI: 13.1-14.7%), with an APC/AAPC of 2.1% (95% CI: 1.1-3.2%, P <0.05). Significant increases were observed among adults aged 18-39 years and rural residents. Undiagnosed diabetes rose from 3.5% (95% CI: 3.2-4.0%) to 7.2% (95% CI: 6.6-7.9%) with an APC/AAPC of 4.1% (95% CI: 0.5-7.3%, P <0.05). However, diabetes awareness and treatment rates showed annual declines of 1.4% (95% CI: -3.0% to -0.2%, P <0.05) and 1.3% (95% CI: -2.6% to -0.2%, P <0.05), respectively. The diabetes control rate decreased from 21.5% to 19.1%, although not statistically significant (APC/AAPC = -1.5%, 95% CI: -5.6% to 1.9%). Overweight and obesity were identified as risk factors for diabetes, with ORs of 1.65 (95% CI: 1.38-1.98) and 2.48 (95% CI: 2.07-2.99), respectively. CONCLUSIONS The prevalence of diabetes in Beijing has significantly increased between 2005 and 2022, particularly among young adults and rural residents. Meanwhile, there has been a concerning decrease in diabetes awareness and treatment rates, while control rates have remained stagnant. Regular blood glucose testing, especially among adults aged 18-59 years, should be warranted. Furthermore, being male, elderly, overweight, or obese was associated with higher diabetes risk, suggesting the needs for targeted management strategies.

BACKGROUND: Whether adherence to a healthy lifestyle is associated with a lower risk of developing pneumonia and a better long-term prognosis remains unclear. This study aimed to investigate associations of individual and combined lifestyle factors (LFs) with the incidence risk and long-term prognosis of pneumonia hospitalization. METHODS: Using data from the China Kadoorie Biobank study, we used the multistate models to investigate the role of five high-risk LFs, including smoking, excessive alcohol drinking, unhealthy dietary habits, physical inactivity, and unhealthy body shape, alone or in combination in the transitions from a generally healthy state at baseline to pneumonia hospitalization or cardiovascular disease (CVD, regarded as a reference outcome), and subsequently to mortality. RESULTS: Most of the five high-risk LFs were associated with increased risks of transitions from baseline to pneumonia and from pneumonia to death, but with different risk estimates. The greater the number of high-risk LFs, the higher the risk of developing pneumonia and long-term mortality risk after pneumonia, with the strength of associations comparable to that of LFs and CVD. Compared to participants with 0-1 high-risk LF, the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for transitions from baseline to pneumonia and from pneumonia to death in those with five high-risk LFs were 1.43 (1.28-1.60) and 1.98 (1.61-2.42), respectively. Correspondingly, the respective HRs (95% CIs) for transitions from baseline to CVD and from CVD to death were 2.00 (1.89-2.11) and 1.44 (1.30-1.59), respectively. The risk estimates changed slightly when further adjusting for the presence of major chronic diseases. CONCLUSION In this Chinese population, unhealthy LFs were associated with an increased incidence and long-term mortality risk of pneumonia.

Objective To investigate the effects of exosomes (Exo) derived from high glucose-stimulated glomerular mesangial cells (GMC) on the kidneys of C57BL/6 mice and the intervention mechanism of Tongluo Yishen Formula (TLYSF). Methods The rat GMC were divided into a normal glucose group (NG, with 5.6 mmol/L glucose) and a high glucose group (HG, with 30 mmol/L glucose). After 24 hours of culture, the supernatant was collected, and exosomes were extracted using the ultracentrifugation method. The exosomes were then identified by transmission electron microscopy and Western blot analysis. Male C57BL/6 mice were divided into three groups: NO-Exo group, NG-Exo group, and HG-Exo group. These groups were respectively administered tail vein injections of PBS buffer, exosomes derived from GMC cultured in normal glucose, and exosomes derived from GMC cultured in high glucose, three times a week for a total of 8 weeks. After 8 weeks, the mice in the HG-Exo group were randomly divided into three subgroups: the HG-Exo group [gavaged with saline], the HG-Exo+TLYSF group [gavaged with TLYSF at 34.32 g/(kg.d)], and the HG-Exo + VAL group [gavaged with valsartan suspension at 10.4 mg/(kg.d)], and the intervention lasted for 4 weeks. Urinary microalbumin (mALb), urinary N-acetyl-β-D-aminoglucosidase (NAG), glycated hemoglobin (HbA1c), serum creatinine (Scr) and urea nitrogen (BUN) were detected. Transmission electron microscopy was used to observe the ultrastructure of renal tissues. TUNEL was used to detect the DNA damage of renal tissue cells. Immunofluorescence was used to detect the expression of NOD-like receptor family pyrin domain containing 3 (NLRP3) and wilms tumor 1(WT-1). RT-PCR was used to detect the mRNA levels of NLRP3, cysteinyl aspartate-specific proteinase 1 (caspase-1), interleukin-1 beta (IL-1β), miR-200c-3p and miR-148a-3p. Western Blot was employed to detect the protein expression of NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), caspase-1 and IL-1β. Results Compared with the NG-Exo group, mice in the HG-Exo group exhibited significantly increased levels of mALb, urinary NAG, Scr and BUN. Transmission electron microscopy revealed ruptured podocyte membranes and swollen mitochondria. The positive rate of cells stained by the TUNEL increased, with elevated optical density of NLRP3 and decreased optical density of WT-1. Additionally, there was a significant increase in the level of NLRP3, caspase-1, IL-1β mRNA, as well as miR-200c-3p and miR-148a-3p. The protein expression of NLRP3, ASC, caspase-1, and IL-1β also increased. Compared with HG-Exo group, mice in the HG-Exo+TLYSF group showed decreased levels of mALb, urinary NAG, Scr, and BUN. The podocyte membranes were relatively intact, and mitochondrial damage was alleviated. The positive rate of cells stained by the TUNEL decreased, along with a reduction in the optical density of NLRP3 and an increase in the optical density of WT-1. Furthermore, the mRNA expression levels of NLRP3, caspase-1, IL-1β, miR-200c-3p, and miR-148a-3p were all downregulated to varying degrees. The protein expression levels of NLRP3, ASC, caspase-1, and IL-1β also decreased. Conclusion Exosomes derived from GMC stimulated by high glucose can damage the kidneys of mice and induce podocyte pyroptosis. TLYSF may ameliorate podocyte pyroptosis by downregulating the expression of exosomal miR-200c-3p and miR-148a-3p and inhibiting the activation of the NLRP3/ASC/caspase-1 pathway.

Small cell lung cancer (SCLC) is the thoracic malignant tumor and accounts for about 15% of lung malignancies and transfer often occurs by the time of diagnosis. Extensive stage-small cell lung cancer (ES-SCLC) accounts for about 2/3 of all SCLC. For many years, radiotherapy has occupied an important position in the treatment of SCLC, especially in the treatment of ES-SCLC, because SCLC is more sensitive to radiotherapy. However, in recent years, immune checkpoint inhibitor has shown more excellent antitumor activity in the treatment of ES-SCLC and become the mainstream argument for the treatment of ES-SCLC. However, will radiotherapy be buried by the times among the therapeutic approaches for ES-SCLC? In this article, we will review the clinical progress of radiotherapy, immunotherapy and combination therapy for ES-SCLC.

Doxorubicin (Dox) is an anthracycline drug widely applied in various malignancies. However, the fatal cardiotoxicity induced by Dox limits its clinical application. Post-transcriptional protein modification via ubiquitination/deubiquitination in cardiomyocytes mediates the pathophysiological process in Dox-induced cardiotoxicity (DIC). In this study, we aimed to clarify the regulatory role and mechanism of a deubiquitinating enzyme, ubiquitin-specific peptidase 13 (USP13), in DIC. RNA-seq analysis and experimental examinations identified that cardiomyocyte-derived USP13 positively correlated with DIC. Mice with cardiac-specific deletion of USP13 were subjected to Dox modeling. Adeno-associated virus serotype 9 (AAV9) carrying cTNT promoter was constructed to overexpress USP13 in mouse heart tissues. Cardiomyocyte-specific knockout of USP13 exacerbated DIC, while its overexpression mitigated DIC in mice. Mechanistically, USP13 deubiquitinates the stimulator of interferon genes (STING) and promotes the autolysosome-related degradation of STING, subsequently alleviating cardiomyocyte inflammation and death. Our study suggests that USP13 serves a cardioprotective role in DIC and indicates USP13 as a potential therapeutic target for DIC treatment.

Most of the current research on depression focuses on neuronal regulation,while the astrocytic mechanism of depression is far from explored.Astrocytes are the most numerous and widely distributed glial cells in the central nervous system.With a complex structural morphology,astrocytes play an important role in a variety of neuropsychiatric disorders by interacting with neuronal synapses,vasculature and other glial cells.Recent studies have shown that astrocytes may be involved in depression by regulating monoamine transmitters,glutamate cycle,synaptic plasticity,energy metabo-lism,and neuroinflammation.This review is intended to inspire new ideas for the treatment of depres-sion and the development of novel drugs based on astrocyte regulation.

Objective:To study the clinicopathological features of Sjogren′s syndrome (SS) with liver injury and to improve the understanding of this disease.Methods:Forty-nine patients with SS complicated with liver injury were collected from Beijing Ditan Hospital, Capital Medical University from October 2008 to January 2022. All patients underwent ultrasound-guided liver biopsy, and all specimens were stained with HE. The histopathologic characteristics were observed and the pathologic indexes were graded. Immunohistochemical stains for CK7, CK19, CD38, MUM1 and CD10 were performed by EnVision method; and special histochemical stains for reticulin, Masson′s trichrome, Rhodanine, Prussian blue, periodic acid Schiff (PAS) and D-PAS stains were conducted .Results:The age of patients ranged from 31 to 66 years, including 3 males and 46 females. SS combined with drug-induced liver injury was the most common (22 cases, 44.9%), followed by autoimmune liver disease (13 cases, 26.5%, including primary biliary cholangitis in eight cases, autoimmune hepatitis in 3 cases, and PBC-AIH overlap syndrome in 2 cases), non-alcoholic fatty liver disease (NAFLD, 9 cases, 18.4%) and other lesions (5 cases, 10.2%; including 3 cases of nonspecific liver inflammation, 1 case of liver amyloidosis, and 1 case of porto-sinusoidal vascular disease). Among them, 28 cases (57.1%) were associated with obvious interlobular bile duct injury, mainly in SS combined with PBC group and drug-induced liver injury group. Twenty-three cases (46.9%) were associated with hepatocyte steatosis of varying degrees. In SS with autoimmune liver disease group, ISHAK score, degree of fibrosis bile duct injury, bile duct remodeling, lymphocyte infiltration of portal area, and plasma cell infiltration, MUM1 and CD38 expression; serum ALP and GGT, IgM; elevated globulin; positive AMA, proportion of AMA-M2 positive and IgM positive were all significantly higher than those in other groups(all P<0.05). Serum ALT, direct bilirubin and SSA positive ratio in SS combined with drug liver group were significantly higher than those in other groups(all P<0.05). The serum total cholesterol level in SS combined with PBC group ( P=0.006) and NALFD group ( P=0.011) were significantly higher than those in other groups ( P<0.05). Conclusions:The pathologic manifestations of SS patients with liver injury are varied. The inflammatory lesions of SS patients with autoimmune liver disease are the most serious, and the inflammatory lesions of SS patients with non-alcoholic fatty liver disease and non-specific inflammation are mild. Comprehensive analysis of liver histopathologic changes and laboratory findings is helpful for the diagnosis of SS complicated with different types of liver injury.

After COVID-19 pandemic, there are still many public health challenges in the world. The double burden of communicable and non-communicable diseases is still heavy in many countries. Mental health and injury are crucial public health problems which are often neglected. Environmental health and food and drug safety are closely related to human health, to which further management and intervention are needed. These problems have different impacts on people at different life stages, resulting in health problems throughout the life course. The current status of public health is far from the requirements set by the Sustainable Development Goals of United Nations or the initiative of "Healthy China 2030". It is necessary for governments and related departments of all countries to consider public health in all policy development to tackle the major challenge to public health.

Objective To screen key genes for ferroptosis in atherosclerosis(AS)using bioinformatics methods and analyze the biological functions of key genes to gain an in-depth understanding of the pathogenesis of AS.Methods AS gene expression profile chip dataset GSE100927 was downloaded from the Gene Expression Omnibus(GEO)database.P＜0.05 and|logFC＞1|were used as the conditions to screen the differential genes of AS.These genes were intersected with ferroptosis gene dataset to screen out the genes related to AS ferroptosis.Gene ontology(GO)functional annotation and enrichment analysis of Kyoto Encyclopedia of Genes and Genomes(KEGG)were carried out.The STRING online analysis tool combined with Cytoscape visualization software was subsequently used to mine genes that play a key role in the biological process of AS,and the AS dataset GSE9874 was used as the verification set to verify the expression of key genes.Blood samples from 30 confirmed AS patients in the cardiovascular department of our hospital from January to March 2023 were collected as the experimental group,while blood samples from 20 healthy volunteers were collected as the control group.Sample RNA was extracted,and quantitative real time polymerase chain reaction(qRT-PCR)was used to verify the selected genes.Results A total of 10 differential genes related to ferroptosis were screened by bioinformatics method.GO functional enrichment analysis showed that differential genes were mainly involved in inflammation,apoptosis,oxidative stress and other biological processes,while KEGG pathway enrichment analysis showed that differential genes were mainly involved in ferroptosis,HIF-1 signaling pathway,and leukocyte migration pathway through endothelial cells.Seven key modules of gene construction were screened out through the protein interaction network,which were FTL,SLC40A1,CYBB,NCF2,HMOX1,DPP4 and ALOX5.GSE9874 was used for verification,and 5 key genes including ALOX5,DPP4,FTL,SLC40A1 and NCF2 were finally screened out.The expression detection of key genes in clinical samples by qRT-PCR showed that compared with the control group,the up-regulated genes in blood of AS group were DPP4(t=1.795,P=0.046),FTL(t=2.218,P=0.029)and SLC40A1(t=2.859,P=0.009),and the down-regulated genes were ALOX5(t=8.039,P＜0.001)and NCF2(t=11.867,P＜0.001),and the differences were significant.The experimental results were consistent with the results of bioinformatics analysis.Subgroup analysis showed that DPP4 expression in plaque group was higher than that in intima thickening group,and the difference was significant(t=2.843,P=0.036).Conclusion The key genes of ferroptosis screened by bioinformatics are AS,ALOX5,DPP4,FTL,SLC40A1 and NCF2,which may be potential targets for the diagnosis and treatment of AS,providing new ideas for the clinical diagnosis and treatment of AS.
