ObjectivesTo analyze the trends in mortality and disease burden of colorectal cancer (CRC) among the registered residents in Danyang City, Jiangsu Province, from 2013 to 2023, and to provide a scientific basis for developing CRC prevention and control strategies. MethodsMortality surveillance data on CRC among the registered residents in Danyang City from 2013 to 2023 were collected and analyzed. Crude mortality rate (CMR), age-standardized mortality rate (ASMR), years of life lost (YLL) due to premature death, and YLL rate were calculated. The annual percentage change (APC) and average annual percent change (AAPC) of CMR, ASMR and YLL rate were calculated with Joinpoint Regression Program 4.9.0.1. ResultsA total of 1 920 deaths from colorectal cancer were recorded in Danyang City during 2013‒2023, with an average annual CMR of 21.75/100 000, which showed an upward trend (APC=6.47%, 95%CI: 4.21%‒8.79%, P<0.001), with higher CMR observed in males than that in females. The overall ASMR by Chinese standard population was 12.10/100 000, with no obvious temporal trends (APC=1.37%, P=0.364). ASMR increased with age, particularly after 45 years. The total YLL due to CRC was 34 711 person-years, with an average YLL rate of 3.93‰. The YLL rate showed a significant upward trend from 2013 to 2023 (APC=4.96%, 95%CI: 4.08%‒18.16%, P<0.001) in Danyang City. ConclusionThe mortality rate of colorectal cancer in Danyang City is relatively high and has shown a rising trend, resulting in an increasing disease burden on the residents year by year. Continued efforts to strengthen CRC prevention and control are needed, particularly targeting males and the elderly population.

Objective To explore the effects and mechanisms of Sanzi Sijun Formula(SSF)in non-alcoholic fatty liver disease(NAFLD)through network pharmacology,molecular docking and molecular dynamics simulation;To carry out experimental validation in vivo and in vitro.Methods The active components and target genes of SSF were screened using TCMSP,TCMIP and TCMIO databases.NAFLD-related targets were screened using the GeneCards database,and the intersection targets were obtained to construct a protein-protein interaction network and screen for core targets.The intersection targets were imported into the DAVID database for GO and KEGG enrichment analysis.Molecular docking was performed using AutoDock Vina software between the key active components of SSF and core targets,and molecular dynamics simulations were conducted using Gromacs 2022 for 100 ns.C57BL/6J mice NAFLD model was established by diet induction.SSF was administered by gavage for 8 weeks.Liver histopathological changes and the levels of non-esterified fatty acids(NEFA)were detected.In vitro NAFLD model was established by inducing AML12 cells with palmitic acid(PA)for 24 hours.SSF-containing serum was added to incubate simultaneously.The lipid accumulation and cell viability were detected.The core targets of SSF intervention in the in vitro and in vivo NAFLD models were verified by RT-qPCR and Western blot.Results Network pharmacological analysis identified 75 active components in SSF and revealed 179 shared targets between these components and NAFLD.Ten main active components including arachidonate,12-senecioyl-2E,8E,10E-atractylodin,cerebrosterol,glycyrrhizol B and sinapic acid,etc.as well as 8 core targets were identified.GO enrichment analysis of targets mainly involved protein phosphorylation,inflammatory response,and apoptosis,while the KEGG enrichment analysis mainly included AGE-RAGE,TNF,AMPK,PPAR and NF-κB signaling pathways.Molecular docking demonstrated that the major active components of SSF exhibited favorable binding affinity and stability with the core targets.Molecular dynamics simulation confirmed the stability of the complex of glyasperin B with AKT1,SIRT1,STAT3,PPARG,and TNF.SSF alleviated the pathological damage of liver tissues in mice NAFLD model,reduced NAS score and NEFA levels in liver tissues(P<0.05).Additionally,SSF reversed lipid accumulation and decreased cell viability of PA-induced AML12 cells(P<0.01).Further in vivo and in vitro experiments demonstrated that SSF significantly reversed the elevated mRNA levels of TNF-α,IL-6,IL-1β and PPARγ and protein expression of STAT3(P<0.05,P<0.01)in NAFLD models,up-regulated the protein levels of SIRT1 and p-Akt/Akt(P<0.05,P<0.01).Conclusion SSF can improve NAFLD of both in vitro and in vivo models.The regulation of multiple targets,such as AKT,SIRT1,STAT3 and PPARG,by its multiple active components,and adjustment of multiple approaches,such as lipid metabolism disorder,inflammatory responses,are involved in the potential underlying mechanisms.

Objective:To investigate the clinical manifestations, gene mutation characteristics, imaging and video electroencephalogram (VEEG) characteristics of patients with dentatorubral-pallidoluysian atrophy (DRPLA).Methods:The clinical data of 9 patients with genetically diagnosed DRPLA in the Neurology Center, Beijing Tiantan Hospital, Capital Medical University from January 2018 to January 2023 were collected, and the clinical data of DRPLA patients reported in China were retrieved and summarized.Results:A total of 45 cases were included. The clinical characteristics were summarized as follows: (1) The male to female ratio of 45 patients was 1.00∶1.25, and the age of onset was (28.11±14.58) years. (2) The main clinical symptoms of juvenile type, early-onset adult type and late-onset adult type were analyzed, and the results showed that the frequency of seizures in juvenile type (16/17) was higher than that in early-onset adult type (8/21) and late-onset adult type (2/7), with statistically significant difference (χ 2=15.971, P<0.001). In addition, the frequency of cognitive impairment in juvenile type (16/17) was also higher than that in early-onset adult type (15/21) and late-onset adult type (2/7), also with statistically significant difference (χ 2=10.177, P=0.005). Cognitive impairment, language disorder and involuntary movement were common in early-onset adult patients, and about half of the patients had ataxia. Ataxia and language disorder were more common in late-onset adult patients, while seizures and cognitive impairment were rare. (3) In imaging, cerebellum and brainstem atrophy was the most common, followed by cortical atrophy and white matter lesions. (4) The number of trinucleotide (CAG) repeats was 53-79, and there was a significant negative correlation between the number of CAG repeats and the age of onset ( r=-0.765, P<0.001), that means the younger the age of onset, the higher the number of CAG repeats. (5) In terms of electrophysiology, 21 patients provided complete VEEG data, of which slowed activity (52%, 11/21) and generalized discharge (71%, 15/21) were more common, and focal discharge (33%, 7/21) was uncommon. Conclusions:DRPLA patients can present with epilepsy, cerebellar ataxia, and other clinical manifestations. Brainstem and cerebellar atrophy and white matter lesions can be relatively characteristic in imaging. In terms of electrophysiology, slowed activity and generalized discharge are more common. DRPLA patients are easy to be misdiagnosed in clinical practice and genetic confirmation helps confirm the diagnosis.

Objective:To investigate the methods and skills required for the safe and swift removal of primary or secondary sacral tumors located between the second (inclusive) and fourth sacral vertebrae.Methods:The clinical images, pathology reports, surgical procedures, operation durations, intraoperative bleeding volumes, and postoperative functional follow-up data of 26 patients undergoing sacral tumor resection at the First Affiliated Hospital of Zhengzhou University and Xinjiang Production and Construction Corps Hospital between May 2020 and February 2025 were retrospectively examined. Additionally, the safety measures for sacral tumor resection and techniques for expedited specimen removal were evaluated.Results:According to magnetic resonance imaging (MRI) findings, all 26 patients presented with sacral tumors located between the second (inclusive) and fourth sacral vertebrae. Specifically, 9 patients were diagnosed with primary sacral tumors, pathologically confirmed as chordomas, while 17 patients had secondary sacral tumors. Among the secondary tumor cases, 12 were attributed to recurrent rectal cancer invading the sacrum, and 5 were due to malignant teratomas invading the sacrum. The 26 patients underwent a treatment strategy that began with managing the relationship between the internal iliac artery, vein branches, and the tumor, followed by the resection of the sacrum. During surgery, the bilateral sciatic foramina were accurately positioned, and the presacral fascia was dissected subsequent to the fracture of the sacrum. Among the 26 patients, 9 underwent sacral tumor resection directly through the posterior sacral approach. The average operation time for these patients was (71.1±4.9) minutes, with average blood loss of (186.7±72.8) milliliters. On the other hand, 17 patients underwent sacral tumor resection by transitioning from the supine position to the prone knife position through a combined abdominal and sacral approach. The average operation time for this group was (213.5±19.3) minutes, with average blood loss of (480.0±93.0) milliliters, significantly longer than that of the posterior sacral approach. The follow-up period ranged from 1 to 48 months, with a median of 20 months, ending on March 31, 2025. During this time, 26 patients achieved autonomous defecation with the aid of medication. None of the patients reported any functional movement disorders or pain in their lower limbs. It was observed that two out of the 26 patients developed distant metastasis, while the remaining 24 patients survived without any tumors.Conclusion:By pretreated the relationship between the internal iliac vessels and sacral tumors prior to resecting sacral tumors, utilizing the approach of initially fracturing the sacrum followed by rupturing the presacral fascia, the tumor can be entirely eliminated, resulting in a brief surgical procedure, reduced intraoperative bleeding, and minimal postoperative complications.

Objective:To explore the clinical efficacy of "four-step" aortic valve anatomic repair for bicuspid aortic valve(BAV) with aortic regurgitation(AR).Methods:From August 2021 to November 2024, a total of 298 consecutive patients with BAV-AR underwent aortic valve anatomic repair(AVr) in Shanghai Zhongshan Hospital Fudan University, 266 males and 32 females, with age of 39(29.5, 48.5) years. All patients underwent " four-step" three-dimensional anatomic repair of the aortic annulus and leaflets, 129(43.3%) patients via upper mini-sternotomy and 169(56.7%) patients via conventional median sternotomy, with the main steps including: (1) deep dissecting and annuloplasty of the virtual basal ring(VBR); (2) symmetrical repairing of leaflets; (3) replacement or remodeling of the sinus of Valsalva; (4) annuloplasty of the sinotubular junction(STJ). Basal and perioperative data were retrospectively collected, and statistical analysis was performed in conjunction with follow-up data.Results:All patients successfully underwent anatomical repair without transferring to valve replacement during operation. Among them, 43 patients underwent aortic root reimplantation technique(Reimplantation group), while 255 patients underwent modified aortic root sleeve remodeling technique(Sleeve group). The median cardiopulmonary bypass time for the Reimplantation and Sleeve groups were 154(134, 169) minutes and 111(95, 129) minutes, respectively( P<0.05); the median aortic cross-clamp time were 112(100, 131) minutes and 80(67, 94) minutes, respectively( P<0.05). Preoperative TEE showed 35 patients(81.4%) and 229 patients(89.8%) with moderate and severe AR in Reimplantation and Sleeve groups, respectively. Postoperative TEE showed 41 patients(95.3%) with no/trace AR and 2 patients(4.7%) with central mild AR in Reimplantation group, while 212 patients(83.1%) with no/trace AR and 43 patients(16.9%) with central mild AR in Sleeve group. Follow-up was completed in all patients, with a median follow-up of 12.9(4.7, 21.2) months. Echocardiography was obtained in 271 patients(90.9%) at the latest follow-up, including no/trace AR in 167 patients(56.0%), mild AR in 89 patients(29.9%), moderate AR in 14 patients(4.7%), and severe AR in 1 patient(0.3%). Conclusion:Aortic valve anatomic repair by standardized "four-step" approach is safe and reproducible. Satisfied short- and mid-term outcome have obtained in selected BAV-AR patients.

Objective:To explore the risk factors of acute Kemmochi type V anterior talofibular ligament (ATFL) injury in X-ray negative children and their predictive efficacy .Methods:A retrospective cohort study was conducted to analyze the clinical data of 92 children with X-ray negative ATFL injury, who were treated at the outpatient department of Jinan Children′s Hospital from June 2023 to March 2025, including 55 boys and 37 girls, aged 5-14 years [8.8(7.0, 11.0)years]. The cause of injury was low-energy ankle sprain and X-ray examination showed no fracture, ie, X-ray negative. According to the Kemmochi classification for ATFL injury, the injury was classified as type V (Kemmochi type V group) in 42 patients and type I-IV (non-Kemmochi type V group) in 50. Gender, age, side of injury, time from injury to first visit, physical examination at the first visit [positive result of ankle inversion test, weight-bearing ability assessment, visual analogue score (VAS)], X-ray examination at the first visit (presence of os subfibulare), and musculoskeletal ultrasound examination at the first visit (swelling degree of ATFL, ankle joint effusion, enhanced blood flow signal of ATFL) were recorded in both groups. Univariate analysis and binary Logistic regression analysis were used to evaluate and determine the independent risk factors for X-ray negative Kemmochi type V ATFL injury in children. The receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to evaluate the predictive efficacy of each independent risk factor for Kemmochi type V ATFL injury. Results:Univariate analysis showed significant differences between the two groups in age, VAS, ATFL swelling degree, and ankle joint effusion ( P<0.05) but no significant differences in gender, side of injury, time from injury to the first visit, positive result of ankle inversion test, weight-bearing ability assessment, presence of os subfibulare or enhanced blood flow of ATFL ( P>0.05). Binary Logistic regression analysis indicated that age ( OR=0.79, 95% CI 0.65, 0.97, P<0.05) and ATFL swelling degree ( OR=6.97, 95% CI 1.38, 35.32, P<0.05) were significantly correlated with Kemmochi type V ATFL injury in X-ray negative children. ROC curve analysis showed that the AUC for age and ATFL swelling degree were 0.65(95% CI 0.54, 0.75) and 0.78(95% CI 0.68, 0.86) and the AUC for age combined with ATFL swelling degree was 0.83(95% CI 0.74, 0.90). The optimal threshold values of age and ATFL swelling degree were 9.3 years and 1.0 mm. Conclusions:Age and ATFL swelling degree are independent risk factors for Kemmochi type V ATFL injury in X-ray negative children. Both age and ATFL swelling degree have relatively high independent predictive efficacy, and the combined predictive efficacy of the two is even higher.

OBJECTIVES: To evaluate the correlation of mean arterial oxygen tension (PaO₂) during the first 24 h following intensive care unit (ICU) admission with mortality in critically ill patients with acute kidney injury (AKI) and determine the optimal PaO₂ threshold for devising oxygen therapy strategies for these patients. METHODS: We collected the clinical data of ICU patients with AKI from the MIMIC-IV database. Based on the optimal first 24-h PaO₂ threshold determined by receiver operating characteristic (ROC) curve analysis and the Youden index maximization principle, we classified the patients into hyperoxia group (with PaO₂ ≥137.029 mmHg) and hypoxemia group (PaO₂<137.029 mm Hg). Multivariable logistic regression and propensity score matching were used to evaluate the correlation of first 24-h PaO₂ levels with in-hospital mortality of the patients. RESULTS: Among the 18 335 patients, 46.7% were in the hyperoxia group, who had an overall mortality rate of 16.9%. The optimal PaO₂ threshold (137.029 mm Hg) had a sensitivity of 78.3%, a specificity of 63.7%, and an AUC of 0.76 (95% CI: 0.74=0.78). Hyperoxia within the first 24 h after ICU admission was associated with a significantly lower in-hospital mortality (OR=0.78) and 90-day mortality (OR=0.77), particularly in stage 1 AKI patients. A non-linear relationship was identified between PaO₂ and mortality of the patients (P<0.001). Kaplan-Meier survival curves indicated a significantly increased 90-day survival rate in the patients in hyperoxia group (P<0.001), who also had shorter durations of mechanical ventilation, less vasopressor use, and shorter lengths of hospital/ICU stay. CONCLUSIONS Maintenance of a PaO₂ level ≥137.029 mmHg within 24 h after ICU admission may improve clinical outcomes of critically ill AKI patients, which underscores the importance of targeted oxygen delivery in ICU care.

Objective : To investigate the role of AdipoRon, an adiponectin receptor agonist, in treatment of carbon tetrachloride(CCl4) induced liver fibrosis mice model and the mechanisms. Methods : Forty mice were randomly divided into control group, model group, L-AdipoRon group and H-AdipoRon group, with 10 mice in each group. Hepatic fibrosis was induced by intraperitoneal injection of CCl4solution. The mice in L-and H-AdipoRon groups were given 100 mg/kg and 200 mg/kg AdipoRon by gavage, respectively. The activities of serum aspartate aminotransferase(AST) and alanine aminotransferase(ALT) were detected by biochemical method. Liver histopathological changes and fibrosis were detected by HE staining, Masson staining and Sirius scarlet stain. The protein expression levels of Collagen I, α-smooth muscle actin(α-SMA), matrix metalloproteinase 1(MMP-1) and matrix metalloproteinase inhibitor 1(TIMP-1) in mice liver were detected by Western blot. Lipid deposition in liver were detected by oil red O staining. The percentage(%) of CD68+ iNOS+ positive M1-type macrophages in the liver were detected by immunofluorescence. The expression levels of fatty acid synthetase(Fasn), stearoyl-CoA desaturase 1(Scd1), fatty acid transporter(Cd36), peroxissome proliferator activated receptor-α(Pparα) and carnitine palmitoyl transferase 1α(Cpt1α) in mice liver tissues, as well as M1 macrophage-related genes interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) and M2 macrophage-related genes arginase 1(Arg1), Chil3 chitinase-like 3(Ym-1) were detected by RT-qPCR assay. Results : Compared with model group, in low-dose AdipoRon group and high-dose AdipoRon group, serum ALT and AST activities significantly decreased(P<0.05); liver tissues structure were damaged, liver cells degeneration and inflammatory cells infiltration were improved; collagen fiber deposition was also significantly reduced; the relative expression levels of Collagen I, α-SMA and TIMP-1 proteins were significantly down-regulated(P<0.05), while the relative expression levels of MMP-1 protein were significantly up-regulated(P<0.05); the lipid droplets deposition in livers were significantly reduced. The relative Fasn, Scd1 and Cd36 mRNA expression levels in liver tissues were significantly down-regulated(P<0.05), and the relative Pparα and Cpt1α mRNA expression levels were significantly up-regulated(P<0.05); the percentage(%) of CD68+ iNOS+ positive M1-type macrophages significantly decreased(P<0.05); the relative IL-6 and TNF-α mRNA expression levels significantly decreased(P<0.05), the relative Arg1 and Ym-1 mRNA expression levels were significantly up-regulated(P<0.05). In addition, the improvement effects of high-dose AdipoRon group were better than those of low-dose AdipoRon group(P<0.05). Conclusion AdipoRon can improve the disorder of lipid metabolisms, inhibit the M1 type macrophages polarization, and improve the liver fibrosis in CCl4-induced liver fibrosis mice model.
