In situ Hg2+ improved the peroxidase-like activity and triggered "ON" the oxidase-like activity of yolk-shell Co3S4 microspheres for the detection of Hg2.

Exploring highly active nanozymes is an important task to realize the real-time detection of some heavy metal ions in water. In this work, yolk-shell Co3S4 microspheres have been verified to possess excellent peroxidase-like activity, which can be further improved by adding Hg2+. Very interestingly, Hg2+ can trigger "ON" the oxidase-like activity of Co3S4 microspheres. The dual peroxidase-/oxidase-like activity of the yolk-shell Co3S4 microspheres is evaluated by using the chromogenic substrate 3,3',5,5'-tetramethylbenzidine (TMB). Furthermore, comprehensive studies verify that the enhanced peroxidase-like activity, together with the "ON" oxidase-like activity of the yolk-shell Co3S4 microspheres, is attributed to the in situ generation of HgS on the surface of Co3S4 microspheres and then the release of more active sites. Importantly, the in situ generated HgS on the surface of Co3S4 microspheres can form a heterojunction, which also accelerates the catalytic process. During the catalytic reaction, some active species (O2- and h+) can be detected by ESR. Thus, a colorimetric sensing platform based on Hg2+-triggered signal amplification has been successfully constructed, which can be validated by the detection of Hg2+ residue in environmental water.

Research on Unsupervised Low-Light Railway Fastener Image Enhancement Method Based on Contrastive Learning GAN.

The railway fastener, as a crucial component of railway tracks, directly influences the safety and stability of a railway system. However, in practical operation, fasteners are often in low-light conditions, such as at nighttime or within tunnels, posing significant challenges to defect detection equipment and limiting its effectiveness in real-world scenarios. To address this issue, this study proposes an unsupervised low-light image enhancement algorithm, CES-GAN, which achieves the model's generalization and adaptability under different environmental conditions. The CES-GAN network architecture adopts a U-Net model with five layers of downsampling and upsampling structures as the generator, incorporating both global and local discriminators to help the generator to preserve image details and textures during the reconstruction process, thus enhancing the realism and intricacy of the enhanced images. The combination of the feature-consistency loss, contrastive learning loss, and illumination loss functions in the generator structure, along with the discriminator loss function in the discriminator structure, collectively promotes the clarity, realism, and illumination consistency of the images, thereby improving the quality and usability of low-light images. Through the CES-GAN algorithm, this study provides reliable visual support for railway construction sites and ensures the stable operation and accurate operation of fastener identification equipment in complex environments.

Association between healthy lifestyle factors and health-related quality of life among Chinese adolescents: the moderating role of gender.

BACKGROUND: To examine the associations of the independent and combined healthy lifestyle factors with health-related quality of life (HRQOL) in adolescents, and to test the moderating role of gender. METHODS: This cross-sectional study included 5125 adolescents aged between 11 and 20 years. They provided self-reported data on six healthy lifestyle factors, including never smoking, never drinking, good sleep quality, sufficient sleep duration, appropriate Internet use, and adequate physical activity. Adolescents' HRQOL was evaluated using the Pediatric Quality of Life Inventory version 4.0. Linear regression models were conducted to explore the association of individual and combined healthy lifestyle factors with adolescents' HRQOL. We further performed stratified analyses and likelihood ratio test to explore the moderating role of gender in these associations. RESULTS: Of the included adolescents, the proportions with 0-2, 3, 4, and 5-6 healthy lifestyle factors were 13.6%, 26.4%, 44.3%, and 15.7%, respectively. Compared to adolescents with composite healthy lifestyle scores of 0-2, those with scores of 3, 4, or 5-6 had significantly higher HRQOL scores across all dimensions, summary scales, and total scale in both unadjusted and adjusted models. Specifically, adolescents with 5-6 healthy lifestyle factors had a total scale score that was 19.03 (95%CI: 17.76 to 20.30) points higher than their counterparts who only had 0-2 healthy lifestyle factors. Significant dose-response patterns were also observed in aforementioned associations. Gender was a significant moderator in the associations between composite healthy lifestyle groups and HRQOL scores, except for the social functioning dimension. CONCLUSIONS: Our results confirmed that combined healthy lifestyle factors were associated with improved HRQOL among adolescents, with a stronger association observed in girls. These findings underscore the necessity for education and healthcare authorities to design health-promoting strategies that encourage multiple healthy lifestyle factors in adolescents, with the objective of enhancing their overall health outcomes.

Use of magnetic powder to effectively improve the denitrification employing the activated sludge fermentation liquid as carbon source.

Nitrogen removal is often limited in municipal wastewater treatment due to the lack of sufficient carbon source. Utilizing volatile fatty acids (VFAs) from waste activated sludge (WAS) fermentation broth as a carbon source is an ideal alternative to reduce the cost for wastewater treatment plants (WWTPs) and improve denitrification efficiency simultaneously. In this study, an anaerobic system was applied for simultaneous denitrification and WAS fermentation and the addition of magnetic microparticles (MMP) were confirmed to enhance both denitrification and WAS fermentation. Firstly, the addition of MMP increased the nitrate reduction rate by over 25.36% and improve the production of N2. Additionally, the equivalent chemical oxygen demand (COD) of the detected VFAs increased by 7.06%-14.53%, suggesting that MMP promoted the WAS fermentation. The electron transfer efficiency of denitrifies was accelerated by MMP via electron-transporting system (ETS) activity and cyclic voltammetry (CV) experiments, which might result in the promotional denitrification and WAS fermentation performance. Furthermore, the high-throughput sequencing displayed that, MMP enriched key microbes capable of degrading the complex organics (Chloroflexi, Synergistota and Spirochaetota) as well as the typical denitrifies (Bacteroidetes_vadinHA17 and Denitratisoma). Therefore, this study provides a novel strategy to realize simultaneous WAS utilization and denitrification for WWTPs.

Enhancement Strategy of Photoelectrocatalytic Activity of Cobalt-Copper Layer Double Hydroxide toward Methanol Oxidation: Cerium Doping and Modification with Porphyrin.

Designing durable, high-active, and low-cost noble-metal-free photoelectrocatalysts for methanol electrooxidation is highly demanded but remains a challenge. Herein, the photoelectrocatalytic activity of cobalt-copper layer double hydroxide (CoCu-LDH) for methanol oxidation reaction (MOR) in the alkaline media under light was remarkably enhanced by cerium (Ce) doping and further by 5,10,15,20-tetrakis(4-carboxylphenyl)porphyrin (TCPP) modification. TCPP/Ce-CoCu-LDH exhibits a remarkable mass activity of 1788.2 mA mg-1 in 1 mol L-1 KOH with 1 mol L-1 methanol under light, which is 2.3 and 1.8 times higher than that of CoCu-LDH (782.2 mA mg-1) and Ce-CoCu-LDH (987.4 mA mg-1). The UV-vis diffuse reflectance spectra and photoluminescence emission spectra reveal that TCPP/Ce-CoCu-LDH can effectively utilize the visible light and inhibit the electron-hole pairs' recombination because of the introduction of porphyrin. Furthermore, more active sites and the greater electrical conductivity of TCPP/Ce-CoCu-LDH also contributed to the high photoelectrocatalytic activity. Thus, TCPP/Ce-CoCu-LDH can be used as a low-cost alternative for Pt-based catalyst toward MOR.

Stimuli-responsive DNA-based hydrogels for biosensing applications.

The base sequences of DNA are endowed with the rich structural and functional information and are available for the precise construction of the 2D and 3D macro products. The hydrogels formed by DNA are biocompatible, stable, tunable and biologically versatile, thus, these have a wide range of promising applications in bioanalysis and biomedicine. In particular, the stimuli-responsive DNA hydrogels (smart DNA hydrogels), which exhibit a reversible and switchable hydrogel to sol transition under different triggers, have emerged as smart materials for sensing. Thus far, the combination of the stimuli-responsive DNA hydrogels and multiple sensing platforms is considered as biocompatible and is useful as the flexible recognition components. A review of the stimuli-responsive DNA hydrogels and their biosensing applications has been presented in this study. The synthesis methods to prepare the DNA hydrogels have been introduced. Subsequently, the current status of the stimuli-responsive DNA hydrogels in biosensing has been described. The analytical mechanisms are further elaborated by the combination of the stimuli-responsive DNA hydrogels with the optical, electrochemical, point-of-care testing (POCT) and other detection platforms. In addition, the prospects of the application of the stimuli-responsive DNA hydrogels in biosensing are presented.

Comorbid depression and obesity, and its transition on the risk of functional disability among middle-aged and older Chinese: a cohort study.

BACKGROUND: Evidence has indicated that depression and obesity were associated with functional disability, independently. However, little is known about the detrimental impact of comorbid depression and obesity, as well as its transition on functional disability. This study investigated the association of baseline depression-obesity status and its dynamic change with incident functional disability among middle-aged and older Chinese. METHODS: This cohort study included 5507 participants aged ≥45 years from the 2011 and 2015 waves of China Health and Retirement Longitudinal Study. Depression was defined with a score ≥ 10 using the 10-item Centre for Epidemiologic Studies Depression Scale. Obesity was defined as body mass index ≥28 kg/m2. Participants were cross-classified by depression and obesity status at baseline, and its change during follow-up. Logistic regression models were constructed to evaluate the association of baseline depression-obesity status and its transition with incident functional disability defined by the Katz index of activities of daily living scale. RESULTS: Over four-year follow-up, 510 (9.3%) participants developed functional disability. Individuals with baseline comorbid depression and obesity had the highest risk of functional disability (OR = 2.84, 95% CI: 1.95-4.15) than non-depressive participants without obesity, or those with depression or obesity alone. When investigating the dynamic changes of depression-obesity status on functional disability incidence, those with stable comorbidity throughout two surveys had the greatest risk of functional disability (OR = 4.06, 95% CI: 2.11-7.80). Progression of depression-obesity status was associated with increased risk of functional disability, while regression from baseline to follow-up was linked to attenuated risk estimates. CONCLUSIONS: Among middle-aged and older Chinese adults, the risk of functional disability was exaggerated with comorbid depression and obesity. Our data further suggest that transitions of depression and obesity over time are associated with the risk of developing functional disability.

Association between systemic inflammation and activities of daily living disability among Chinese elderly individuals: the mediating role of handgrip strength.

BACKGROUND: Aging is accompanied by chronic low-grade inflammation (inflammaging), which is a risk factor for low handgrip strength (HGS) and activities of daily living (ADL) disability. AIMS: To explore the association between C-reactive protein (CRP) and ADL disability in Chinese elderly individuals and to further evaluate the mediating role of HGS in this association. METHODS: We used data from the China Health and Retirement Longitudinal Study (CHARLS) that were collected in 2015. A total of 3601 elderly individuals aged ≥ 60 years were included. Baron and Kenny's causal steps method was used to explore the possible mediating role of HGS in the associations between CRP and ADL disability. Karlson-Holm-Breen method was further applied to decompose total effect into direct effect and indirect effect via HGS. Subgroup analysis was conducted by sex and age. RESULTS: A high level of CRP (≥ 3 mg/L) was significantly associated with ADL disability after adjustment for covariates (OR = 1.50, 95% CI = 1.17-1.94). After introducing HGS into the model, the risk estimate was reduced but still significant (OR = 1.40, 95% CI = 1.08-1.81). The proportional mediation through HGS was 14.71%. Similar results were observed in both sexes and in participants aged < 70 years. CONCLUSION: CRP was positively associated with the risk of ADL disability in Chinese elderly individuals, and this association was mediated by HGS. Improving muscle strength in combination with anti-inflammatory treatment may have a beneficial effect to maintain ADL ability. Further randomized controlled trials on this topic are necessary.

Fabrication of Magnetic Al-Based Fe3O4@MIL-53 Metal Organic Framework for Capture of Multi-Pollutants Residue in Milk Followed by HPLC-UV.

The efficient capture of multi-pollutant residues in food is vital for food safety monitoring. In this study, in-situ-fabricated magnetic MIL-53(Al) metal organic frameworks (MOFs), with good magnetic responsiveness, were synthesized and applied for the magnetic solid-phase extraction (MSPE) of chloramphenicol, bisphenol A, estradiol, and diethylstilbestrol. Terephthalic acid (H2BDC) organic ligands were pre-coupled on the surface of amino-Fe3O4 composites (H2BDC@Fe3O4). Fe3O4@MIL-53(Al) MOF was fabricated by in-situ hydrothermal polymerization of H2BDC, Al (NO3)3, and H2BDC@Fe3O4. This approach highly increased the stability of the material. The magnetic Fe3O4@MIL-53(Al) MOF-based MSPE was combined with high-performance liquid chromatography-photo diode array detection, to establish a novel sensitive method for analyzing multi-pollutant residues in milk. This method showed good linear correlations, in the range of 0.05-5.00 µg/mL, with good reproducibility. The limit of detection was 0.004-0.108 µg/mL. The presented method was verified using a milk sample, spiked with four pollutants, which enabled high-throughput detection and the accuracies of 88.17-107.58% confirmed its applicability, in real sample analysis.

Dual Sensitization Smartphone Colorimetric Strategy Based on RCA Coils Gathering Au Tetrahedra and Its Application in the Detection of CK-MB.

In recent years, the combination of DNA nanotechnology and biosensing has been extensively reported. Herein, we attempted to develop a dual sensitization smartphone colorimetric strategy based on rolling circle amplification (RCA) coils gathering Au tetrahedra and explore its application. The dual sensitization effect of this strategy was achieved by rolling circle amplification (RCA) and Au tetrahedra. Under the initiation of the complementary DNA, a large number of ssDNA were generated, achieving amplification of the reaction signal. At the same time, due to the formation of Au tetrahedra, more gold nanoparticles could be gathered under the same conditions, and the signal would be amplified again. Using software ImageJ, the gray value of the reaction solution can be analyzed, detecting the target timely under the practical conditions of lack of equipment. By selecting aptamers with strong binding affinity, we applied this strategy to detect creatine kinase isoenzymes (CK-MB), showing a limit of detection of 0.8 pM, which performed well in actual detection and can meet the needs for real-time detection of CK-MB. Therefore, a universal detection platform was developed, which has broad application prospects in biosensing, clinical diagnosis, food detection, and other fields.

Targeted delivery of nitric oxide via a 'bump-and-hole'-based enzyme-prodrug pair.

The spatiotemporal generation of nitric oxide (NO), a versatile endogenous messenger, is precisely controlled. Despite its therapeutic potential for a wide range of diseases, NO-based therapies are limited clinically due to a lack of effective strategies for precisely delivering NO to a specific site. In the present study, we developed a novel NO delivery system via modification of an enzyme-prodrug pair of galactosidase-galactosyl-NONOate using a 'bump-and-hole' strategy. Precise delivery to targeted tissues was clearly demonstrated by an in vivo near-infrared imaging assay. The therapeutic potential was evaluated in both rat hindlimb ischemia and mouse acute kidney injury models. Targeted delivery of NO clearly enhanced its therapeutic efficacy in tissue repair and function recovery and abolished side effects due to the systemic release of NO. The developed protocol holds broad applicability in the targeted delivery of important gaseous signaling molecules and offers a potent tool for the investigation of relevant molecular mechanisms.

Systematic review and meta-analysis of the association between paediatric obesity and telomere length.

AIM: This systematic review and meta-analysis aimed to assess the association between paediatric obesity and telomere length. METHODS: We conducted a comprehensive literature search for original studies assessing the associations between obesity and telomere length in children. Fixed or random effects with inverse-variance meta-analysis were used to estimate the standardised mean difference (SMD) and its 95% confidence interval (95% CI) between overweight or obese and normal-weight children. Heterogeneity was assessed using the I2 statistic, and meta-regression analyses were used to evaluate the potential source of heterogeneity. Subgroup analysis was further conducted by sex. RESULTS: A total of 11 studies were included. The meta-analysis showed that children who were overweight or obese had shorter telomere length than normal-weight children (SMD: -0.85; 95% CI: -1.42 to -0.28; p < 0.01). However, significant heterogeneity was present (I2  = 97%; p < 0.01). Study design, methods used for measuring telomere length, tissue types, mean age, and percentage of boys were not the source of heterogeneity revealed by meta-regression analysis. The inverse trend was significant only in boys, but not in girls. CONCLUSION: There was a negative association between paediatric obesity and telomere length. Weight control in children might have beneficial effect on telomere length.

Modified endometriosis fertility index is more accurate to predict the non-ART pregnancy rate following surgery: a cohort of Chinese women.

OBJECTIVE: To examine whether a modified endometriosis fertility index (EFI) can better predict the rate of pregnancy without assisted reproductive technologies (ART) after laparoscopic surgery in infertile Chinese women with endometriosis. METHODS: 564 infertile women undergoing laparoscopy for endometriosis were retrospectively collected from January 2014 to December 2018. 472 patients were used to modify the EFI based on new, optimal cutoffs for its predictor variables. The predictive accuracy of the modified EFI was examined in the other 92 patients. RESULTS: Among the patients for the EFI modification, the multivariable Cox regression results showed that historical factors made more contribution in predicting non-ART pregnancy rate than surgical factors both in modified EFI (C-index: historical factors 0.617 vs surgical factors 0.558) and original EFI (C-index: historical factors 0.600 vs surgical factors 0.549). No significant relationship between the prior pregnancy and post-operative non-ART pregnancy rates was detected by both modified EFI and original EFI (p = 0.530 and 0.802, respectively). To assess the predictive effect of modified EFI, the two versions of modified EFI not only had higher predictive accuracy (C-index: 0.627 and 0.632) for non-ART pregnancy rates than that of the original EFI (C-index: 0.602) in the patients undergoing surgery during 2014-2017, but also higher than that of the original EFI (C-index: 0.638 and 0.612 vs 0.560) in the externally validated population in 2018. CONCLUSIONS: A modified EFI based on population-specific optimal cutoffs and weights might be more suitable for estimating the rate of non-ART pregnancy after laparoscopic surgery in infertile women with endometriosis.

Prognostic value of TP53 concurrent mutations for EGFR- TKIs and ALK-TKIs based targeted therapy in advanced non-small cell lung cancer: a meta-analysis.

BACKGROUND: The prognostic significance of TP53 concurrent mutations in patients with epidermal growth factor receptor (EGFR)- or anaplastic lymphoma kinase (ALK)- mutated advanced non-small-cell lung cancer (NSCLC) who received EGFR-tyrosine kinase inhibitors (TKIs) or ALK-TKIs based targeted therapy remains controversial. Therefore, the present meta-analysis was performed to investigate the association between TP53 concurrent mutations and prognosis of patients with advanced NSCLC undergoing EGFR-TKIs or ALK-TKIs treatments. METHODS: Eligible studies were identified by searching the online databases PubMed, Embase, Medline, The Cochrane library and Web of Science. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated to clarify the correlation between TP53 mutation status and prognosis of patients. This meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS: In total, 15 studies with 1342 patients were included for final analysis. Overall, concurrent TP53 mutation was associated with unfavorable progression-free survival (PFS) (HR = 1.88, 95%CI: 1.59-2.23, p < 0.001, I2 = 0.0%, P = 0.792) and overall survival (OS) (HR = 1.92, 95%CI: 1.55-2.38, p < 0.001, I2 = 0.0%, P = 0.515). Subgroup analysis based on type of targeted therapy (EGFR-TKIs or ALK-TKIs, pathological type of cancer (adenocarcinoma only or all NSCLC subtypes) and line of treatment (first-line only or all lines) all showed that TP53 mutations was associated with shorter survivals of patients with EGFR-TKIs or ALK-TKIs treatments. Particularly, in patients with first-line EGFR-TKIs treatment, significantly poorer prognosis was observed in patients with TP53 concurrent mutations (pooled HR for PFS: 1.69, 95% CI 1.25-2.27, P < 0.001, I2 = 0.0%, P = 0.473; pooled HR for OS: 1.94, 95% CI 1.36-2.76, P < 0.001, I2 = 0.0%, P = 0.484). Begg's funnel plots and Egger's tests indicated no significant publication bias in this study. CONCLUSIONS: This meta-analysis indicated that concurrent TP53 mutations was a negative prognostic factor and associated with poorer outcomes of patients with EGFR-TKIs or ALK-TKIs treatments in advanced NSCLC. In addition, our study provided evidence that TP53 mutations might be involved in primary resistance to EGFR-TKIs treatments in patients with sensitive EGFR mutations in advanced NSCLC.

2-Bromopalmitate targets retinoic acid receptor alpha and overcomes all-trans retinoic acid resistance of acute promyelocytic leukemia.

Fatty acid oxidation dependency of leukemia cells has been documented in recent studies. Pharmacologic inhibition of fatty acid oxidation, thereby, displays significant effects in suppressing leukemia. 2-Bromopalmitate, a palmitate analogue, was initially identified as an inhibitor of fatty acid oxidation, and recently recognized as an inhibitor of protein palmitoylation. However, the effects of 2-Bromopalmitate on leukemia and its cellular targets remain obscure. Herein, we discover in cultured cell lines, a transplantable mouse model, and primary blasts that 2-Bromopalmitate presents synergistic differentiation induction with all-trans retinoic acid in acute promyelocytic leukemia. Moreover, 2-Bromopalmitate overcomes all-trans retinoic acid resistance in all-trans retinoic acid-resistant cells and leukemic mice. Mechanistically, 2-Bromopalmitate covalently binds at cysteine 105 and cysteine 174 of retinoic acid receptor alpha (RARα) and stabilizes RARα protein in the presence of all-trans retinoic acid which is known to induce RARα degradation, leading to enhanced transcription of RARα-target genes. Mutation of both cysteines largely abrogates the synergistic effect of 2-Bromopalmitate on all-trans retinoic acid-induced differentiation, demonstrating that 2-Bromopalmitate promotes all-trans retinoic acid-induced differentiation through binding RARα. All-trans retinoic acid-based regimens including arsenic trioxide or chemotherapy, as preferred therapy for acute promyelocytic leukemia, induce adverse events and irreversible resistance. We expect that combining all-trans retinoic acid with 2-Bromopalmitate would be a promising therapeutic strategy for acute promyelocytic leukemia, especially for overcoming all-trans retinoic acid resistance of relapsed acute promyelocytic leukemia patients.

Association of IL-6 Gene (-174 and -572 G/C) Polymorphisms with Proliferative Diabetic Retinopathy of Type 2 Diabetes in a Chinese Population.

PURPOSE: To investigate the association of interleukin (IL)-6 with proliferative diabetic retinopathy (PDR) of type 2 diabetes (T2D) in a Chinese population. METHODS: Two subtypes of the IL-6 promoter (-174 and -572 G/C) were genotyped in 215 T2D patients with PDR and 207 T2D patients with a normal retinal function (controls) using the PCR-RFLP method. The mRNA and protein expression of IL-6 was examined by real-time PCR. RESULTS: T2D patients with PDR had a significantly higher frequency of IL-6 -174 GC (OR 0.58; 95% CI 0.34-0.99; p = 0.011) and IL-6 -572 GG (OR 0.53; 95% CI 0.24-1.14; p = 0.016) than T2D controls. The mRNA expressions of the rs1800795 GC and rs1800796 GG genotype were significantly increased compared to other cases (Fsig = 0.002, p = 0.001, respectively), followed by a relative increase in IL-6 in protein. CONCLUSIONS: IL-6 genotypes of rs1800795 GC and rs1800796 GG might point to a relatively high risk for T2D patients suffering from PDR in a Chinese population and they were associated with elevation of IL-6 expression in both mRNA and protein.

[Advances in the association of ATP-sensitive potassium channels and Parkinson's disease].

ATP-sensitive potassium channels (KATP), as an inward rectifying potassium channel, are widely distributed in many types of tissues. KATP are activated by the depletion of ATP level and the increase in oxidative stress in cells. The activity of KATP couples cell metabolism with electrical activity and results in membrane hyperpolarization. KATP are ubiquitously distributed in the brain, including substantia nigra, hippocampus, hypothalamus, cerebral cortex, dorsal nucleus of vagus and glial cells, and participate in neuronal excitability, mitochondria homeostasis and neurotransmitter release. Accumulating lines of evidence suggest that KATP are the major contributing factors in the pathogenesis of Parkinson's disease (PD). This review discussed the association of KATP with the pathogenic processes of PD by focusing on the roles of KATP on the degeneration of dopaminergic neurons, the functions of mitochondria, the firing pattern of dopaminergic neurons in the substantia nigra, the α-synuclein secretion from striatum, and the microglia activation.

Socioeconomic inequalities in cancer incidence and mortality: An analysis of GLOBOCAN 2022.

BACKGROUND: Given the recent updates in cancer burden estimates by GLOBOCAN 2022, this study was undertaken to provide pertinent perspectives within the context of the Human Development Index (HDI) and major world economies. METHODS: Datasets sourced from GLOBOCAN encompassed cancer cases and deaths across all cancer types in 2022, alongside projections up to 2050. Cancer incidences and deaths of the top 10 cancers within China and four distinct HDI-classified regions were compared using descriptive analyses. Age-standardized incidence rates (ASIRs) and mortality rates (ASMRs) worldwide for the most prevalent cancers in 2022 across ten largest economies and four-tier HDIs were examined. The top five cancer types concerning both incidence and mortality in China were delineated by sex and age group. RESULTS: In males, prostate cancer predominated in countries with low, high (except China), and very high HDI. Prostate and liver cancers were prominent causes of death in countries with low HDI. In females, breast and cervical cancers predominated in countries with low-to-medium HDI. Lung and colorectal cancer incidence and deaths increased with high HDI for both sexes. ASIRs and ASMRs for breast, prostate, lung, and colorectal cancers in the top 10 economies were higher than the global average. However, liver, stomach, and cervical cancers in most Western countries exhibited lower rates. In China, hematologic malignancies (43%) were prevalent among children aged 0-14 years, whereas thyroid cancer led among adolescents and young adults aged 15-39 years. Regarding incidence and mortality, lung cancer predominated for individuals over 40 years, except for females aged 40-59 years, in whom breast cancer predominated. Projected trends indicated substantial increases in new cancer cases (76.6%) and deaths (89.7%) over the next three decades. CONCLUSIONS: Infection- and poverty-related cancer burdens are offset by increased prostate, breast, colorectal, and lung cancer incidence associated with rapid societal and economic transitions. Cancer incidence and mortality patterns in China feature characteristics of developed and developing countries, necessitating tailored, evidence-based, and comprehensive strategies for effective cancer prevention and control.

Application of Intramedullary Calcar Support Plate and Lateral Locking Plate in Elderly Patients with Neer 3 and 4-Part Fractures of Proximal Humerus Through a Deltoid Splitting Approach.

Background: The reduction and fixation of Medial humeral calcar is difficult in the treatment of elderly proximal humerus Neer 3 and 4-part fractures with a single lateral locking plate. Our study investigated the efficacy of an intramedullary calcar supporting plate combined with a lateral locking plate for the treatment of 3- and 4-part fractures of the proximal humerus in the elderly through a deltoid splitting approach. Methods: From June 2022 to December 2022, we treated six elderly patients with Neer 3 and 4-part fractures using proximal humeral intramedullary calcar support plate in combination with lateral locking plate through a deltoid splitting approach. Follow-up time was 6-12 months. Assessment indicators included fracture union, quality of reduction, and complication rate. The Constant-Murley score was used to record shoulder function at 6 months postoperatively. Results: All 6 patients showed fracture union and anatomic reduction. Constant-Murley score was 79.5 (70-90) at 6 months postoperatively. There was no incision non-healing, internal fixation failure, bone non-union or surgical site infection, secondary surgery, or death. Shoulder impingement occurred in 1 case. Conclusion: Proximal humeral intramedullary calcar support plate combined with lateral locking plate fixation through a deltoid splitting approach can effectively maintain fracture reduction, prevent inversion collapse of humeral head and internal fixation failure, and provide satisfactory clinical results at an early stage.

Increased incidence risks of cardiovascular disease among cancer patients: Evidence from a population-based cohort study in China.

BACKGROUND: Cardiovascular disease (CVD) is becoming a major concern among cancer patients, leading to the development of a new field named cardio-oncology. However, previous studies were mainly based on the western population and focused on CVD mortality. Evidence from the Chinese population is limited. Furthermore, few studies investigated the incidence risks of CVD among cancer patients. METHODS: 85,787 eligible cancer patients were included from Hangzhou city, China. Age-standardized standard incidence ratio (SIR) was used to reflect the incidence risks of CVD among cancer patients as compared with the standard population, which was defined as all residents in Hangzhou city during the same period. RESULTS: After three years of follow-up, cancer patients showed elevated incidence risks of CVD (SIR = 1.41, 95%CI: 1.35-1.47) as compared with the standard population. The elevated risks of CVD were highest in the first year after cancer diagnosis (SIR = 1.68, 95%CI: 1.58-1.78), then followed by the second (SIR = 1.21, 95%CI: 1.11-1.31) and the third (SIR = 1.18, 95%CI: 1.07-1.29) year. These results were consistent in males and females. Furthermore, different risks of CVD were observed among different cancer sites. Patients with pancreatic cancer showed the highest risks of CVD, then followed by liver cancer, lung cancer, kidney cancer, gastric cancer, bladder cancer, prostate cancer, and colorectal cancer. CONCLUSIONS: Cancer patients have increased incidence risks of CVD, especially in the first year after cancer diagnosis. The increased risks of CVD vary by different cancer sites. Our findings highlight the importance of paying close attention to the CVD risks among cancer patients.
