ObjectiveTo analyze the incidence rate and mortality of acute myocardial infarction (AMI) and their changing trends among the registered residents in Xiaoshan District, Hangzhou City from 2017 to 2023, so as to provide references for formulating policies related to AMI prevention. MethodsThe morbidity and mortality data of AMI among the registered residents in Xiaoshan District from 2017 to 2023 were collected through the Hangzhou Chronic Disease and Death Cause Monitoring System. Software such as Excel 2019, SPSS 25.0 and Joinpoint 4.9.1.0 were used to calculate the incidence rate, mortality, and average annual percentage change (AAPC) of AMI. ResultsFrom 2017 to 2023, the average annual crude incidence rate, age-standardized incidence rate using China standard population (ASIRC), and the age-standardized incidence rate using World standard population (ASIRW) of AMI in Xiaoshan District were 48.25/100 000, 29.14/100 000, and 21.64/100 000, respectively, and, from which the AAPCs were 5.495%, 6.010%, and 6.533%, respectively, all showing an upward trend. The average annual crude mortality rate, the age-standardized mortality rate using China standard population (ASMRC), and the age-standardized mortality rate using World standard population (ASMRW) were 11.76/100 000, 6.52/100 000, and 4.71/100 000, respectively, from which the AAPCs were -9.669%, -10.433% and -9.615%, respectively, all showing a downward trend. The average annual crude incidence rate of AMI was higher in males (65.87/100 000) than that in females (31.31/100 000). Moreover, the average annual crude mortality rate of AMI was higher in males (14.08/100 000) than that in females (9.52/100 000), and the difference was statistically significant (all P<0.001) .After age grouping, the crude incidence rate of AMI among the residents aged 35-, 45-, 55-, and 65- years in Xiaoshan District from 2017 to 2023 showed an upward trend over time, with AAPCs of 16.993%, 17.149%, 8.523%, and 5.002%, respectively. While the crude mortality rate in residents aged 35-, 75-, and 85-102 years showed an decreasing trend over time, with AAPCs of -23.977%, -15.467%, and -17.415%, respectively, but there was no statistically significant difference in the trends in incidence rate and mortality of other age groups (all P>0.05). ConclusionThe situation of AMI prevention and control among the registered residents in Xiaoshan District is not optimistic, and targeted measures should be strengthened for the male residents aged ≥35 years old.

Objective: To analyze the correlation between serum homocysteine (Hcy) and both folic acid (FA) and sperm DNA fragmentation index (DFI), so as to provide the evidence for male fertility assessment. Methods: Males who visited and measured the serum Hcy in the Reproductive Medicine Center of Huzhou Maternal and Child Health Care Hospital from September 2022 to September 2023 were selected as the study subjects. Sperm quality parameters and sperm DFI were analyzed by collecting sperm. Hcy and FA were measured by collecting venous blood. Participants were stratified into a high Hcy group (Hcy≥15.0 μmol/L) and a normal group (Hcy<15.0 μmol/L). The correlations between serum Hcy and FA and sperm DFI were evaluated using linear regression models. Results: A total of 173 participants were enrolled, including 39 in the high Hcy group and 134 in the normal group. The sperm concentration in the high Hcy group was significantly lower than that in the normal group [(91.77±61.11)×106/mL vs. (144.21±106.82)×106/mL, P<0.05]. No statistically significant differences were observed in semen volume, sperm motility, curvilinear velocity, straight-line velocity, average path velocity, or sperm morphology normal rate (all P>0.05). The FA level in the high Hcy group was lower than that in the normal group [(4.44±1.79) nmol/L vs. (7.64±3.68) nmol/L, P<0.05]. The sperm DFI in the high Hcy group was higher than that in the normal group [(19.21±8.85)% vs. (13.07±6.43)%, P<0.05]. Serum Hcy level showed a negative correlation with FA level (r=-0.369, P<0.05) and a positive correlation with sperm DFI (r=0.351, P<0.05). Conclusion Serum Hcy level is associated with sperm concentration, FA and sperm DFI, suggesting that serum Hcy may affect sperm quality.

Objective: To analyze the incidence trend of colorectal cancer in Xiaoshan District, Hangzhou City from 2010 to 2024, and predict the incidence of colorectal cancer from 2025 to 2027, so as to provide the evidence for improving the prevention and control strategies of colorectal cancer. Methods: Colorectal cancer incidence data from 2010 to 2024 in Xiaoshan District were collected through the Hangzhou Municipal Chronic Disease Monitoring Management System. The crude incidence of colorectal cancer was calculated, and standardized using the data from the Sixth National Population Census in 2010 (Chinese standardized rate) and the Segi's world standard population (world standardized rate). The trend of colorectal cancer incidence from 2010 to 2024 was analyzed using the average annual percent change (AAPC). An exponential smoothing state space model with trigonometric seasonality, box-cox transformation, ARMA errors, trend and seasonal components (TBATS) was established to forecast the crude incidence of colorectal cancer from 2025 to 2027. Results: There were 10 726 new cases of colorectal cancer in Xiaoshan District from 2010 to 2024. The crude incidence, Chinese standardized rate, and world standardized rate of colorectal cancer were 59.25/100 000, 38.62/100 000 and 29.50/100 000, respectively. The crude incidence, Chinese standardized rate, and world standardized rate of colorectal cancer in males were 70.56/100 000, 44.44/100 000and 35.58/100 000, respectively, while those in females were 48.37/100 000, 32.69/100 000 and 23.70/100 000, respectively. The Chinese standardized rate of colorectal cancer was significantly higher in males than in females (P<0.05). The crude incidence of colorectal cancer in males, females and the whole population showed upward trends from 2010 to 2024 (AAPC=4.916%, 3.795% and 4.442%, all P<0.05). The crude incidence of colorectal cancer in the groups of 0-<35, 35-<50, 50-<75 and ≥75 years were 1.75/100 000, 19.86/100 000, 112.28/100 000 and 272.99/100 000, respectively, showing an increasing trend with age (P<0.05). From 2010 to 2024, the crude incidence of colorectal cancer in the ≥75 years group showed an increasing trend (AAPC=4.470%, P<0.05), while no significant trend was observed in other age groups (all P>0.05). TBATS model demonstrated good fitting (predictive) performance, indicating a year-by-year increase in the crude incidence of colorectal cancer across the whole population from 2025 to 2027, with an estimated rate reaching 70.45/100 000 in 2027. Conclusions The crude incidence of colorectal cancer in Xiaoshan District showed an increasing trend from 2010 to 2024, and it is predicted to continue to increase from 2025 to 2027. Males and the elderly are the key populations for colorectal cancer prevention and control.

OBJECTIVE: To investigate the short-term effectiveness of uni-portal non-coaxial spinal endoscopic surgery (UNSES) via crossing midline approach (CMA) in the treatment of free lumbar disc herniation (FLDH). METHODS: Between March 2024 and June 2024, 16 patients with FLDH were admitted and treated with UNSES via CMA. There were 9 males and 7 females with an average age of 55.1 years (range, 47-62 years). The disease duration was 8-30 months (mean, 15.6 months). The pathological segments was L _{3, 4} in 4 cases, L _{4, 5} in 5 cases, and L ₅, S ₁ in 7 cases. The preoperative pain visual analogue scale (VAS) score was 6.9±0.9 and the Oswestry disability index (ODI) was 57.22%±4.16%. The operation time, intraoperative bleeding volume, postoperative hospital stay, and incidence of complications were recorded. The spinal pain and functional status were evaluated by VAS score and ODI, and effectiveness was evaluated according to the modified MacNab criteria. CT and MRI were used to evaluate the effect of nerve decompression. RESULTS: All 16 patients underwent operation successfully without any complications. The operation time was 63-81 minutes (mean, 71.0 minutes). The intraoperative bleeding volume was 47.3-59.0 mL (mean, 55.0 mL). The length of hospital stay after operation was 3-4 days (mean, 3.5 days). All patients were followed up 1-3 months, with 15 cases followed up for 2 months and 14 cases for 3 months. The VAS score and ODI gradually decreased over time after operation, and there were significant differences between different time points ( P<0.05). At 3 months after operation, the effectiveness was rated as excellent in 12 cases and good in 2 cases according to the modified MacNab criteria, with an excellent and good rate of 100%. CT and MRI during follow-up showed a significant increase in the diameter and cross-sectional area of the spinal canal, indicating effective decompression of the canal. CONCLUSION When using UNSES to treat FLDH, choosing CMA for nerve decompression has the advantages of wide decompression range, large operating space, and freedom of operation. It can maximize the preservation of the articular process, avoid fracture and breakage of the isthmus, clearly display the exiting and traversing nerve root, and achieve good short-term effectiveness.

OBJECTIVES: To study the molecular mechanisms of LDH-loaded si-NEAT1 for regulating paclitaxel resistance and tumor-associated macrophage (TAM) polarization in breast cancer. METHODS: qRT-PCR and Western blotting were used to detect the expression of lncRNA NEAT1, miR-133b, and PD-L1 in breast cancer SKBR3 cells and paclitaxel-resistant SKBR3 cells (SKBR3-PR). The effects of transfection with si-NEAT1 and miR-133b mimics on MRP, MCRP and PD-L1 expressions and cell proliferation, migration and apoptosis were investigated using qRT-PCR, Western blotting, scratch and Transwell assays, and flow cytometry. Rescue experiments were conducted using si-NEAT1 and miR-133b inhibitor. Human THP-1 macrophages were cultured in the presence of conditioned media (CM) derived from SKBR3 and SKBR3-PR cells with or with si-NEAT1 transfection for comparison of IL-4-induced macrophage polarization by detecting the surface markers. LDH@si-NEAT1 nanocarriers were constructed, and their effects on MRP, MCRP and PD-L1 expressions and cell behaviors of the tumor cells were examined. THP-1 cells were treated with the CM from LDH@si-NEAT1-treated tumor cells, and the changes in their polarization were assessed. RESULTS: SKBR3-PR cells showered significantly upregulated NEAT1 and PD-L1 expressions and lowered miR-133b expression as compared with their parental cells. Transfection with si-NEAT1 and miR-133b mimics inhibited viability, promoted apoptosis and enhanced MRP and BCRP expressions in SKBR3-PR cells. NEAT1 knockdown obvious upregulated miR-133b and downregulated PD-L1, MRP and BCRP expressions. The CM from SKBR3-PR cells obviously promoted M2 polarization of THP-1 macrophages, which was significantly inhibited by CM from si-NEAT1-transfected cells. Treatment with LDH@si-NEAT1 effectively inhibited migration and invasion, promoted apoptosis, and reduced MRP, BCRP and PD-L1 expressions in the tumor cells. The CM from LDH@si-NEAT1-treated SKBR3-PR cells significantly downregulated Arg-1, CD163, IL-10, and PD-L1 and upregulated miR-133b expression in THP-1 macrophages. CONCLUSIONS LDH@si-NEAT1 reduces paclitaxel resistance of breast cancer cells and inhibits TAM polarization by targeting the miR-133b/PD-L1 axis.

Objective To compare the synergies between the transcutaneous needle electrodes and the ETT surface electrodes used for neurological surveillance in thyroidology,and explore how to identify and protect recurrent laryngeal nerve and vagus nerve when the patient is not suitable for oral plug or surface electrodes are failure.Methods To collect and analyze the clinical data of 32 patients undergoing surgical treatment for thyroid disease,a total of 40 neurons of the recurrent laryngeal nerves and vagus nerves were monitored,and the amplitude and latency were recorded using ETT surface electrodes and transcutaneous needle electrodes for nerve monitoring,respectively.SPSS 26.0 software was used for statistical analysis,paired t-tests were used to analyze and compare the latency periods,and the rank sum test was used to analyze whether there is a difference in the amplitude obtained from stimulation of transcutaneous needle electrodes and ETT surface electrodes.Results When the transcutaneous needle electrodes were used in thyroid surgery,we identified all the nerves,obtained two-phase electrical signals similar to the latency and amplitude of the ETT surface electrodes,and could effectively identify the recurrent laryngeal nerve and vagus nerve[(3.22±0.50)ms vs.(3.85±1.00)ms,P＜0.05]through the incapacity period,with no obvious difference in the monitoring effect from the ETT surface electrodes[(3.04±0.58)ms vs.(3.89±1.07)ms,P＜0.05].At the same time,the visualization and safety of transcutaneous needle electrodes were higher,with great advantages.Conclusion Transcutaneous needle electrodes can effectively assist in identifying and protecting the recurrent laryngeal nerve and vagus nerve,and thus are an important supplement to ETT surface electrodes.

Existing studies have underscored the pivotal role of N-acetyltransferase 10 (NAT10) in various cancers. However, the outcomes of protein-protein interactions between NAT10 and its protein partners in head and neck squamous cell carcinoma (HNSCC) remain unexplored. In this study, we identified a significant upregulation of RNA-binding protein with serine-rich domain 1 (RNPS1) in HNSCC, where RNPS1 inhibits the ubiquitination degradation of NAT10 by E3 ubiquitin ligase, zinc finger SWIM domain-containing protein 6 (ZSWIM6), through direct protein interaction, thereby promoting high NAT10 expression in HNSCC. This upregulated NAT10 stability mediates the enhancement of specific tRNA ac⁴C modifications, subsequently boosting the translation process of genes involved in pathways such as IL-6 signaling, IL-8 signaling, and PTEN signaling that play roles in regulating HNSCC malignant progression, ultimately influencing the survival and prognosis of HNSCC patients. Additionally, we pioneered the development of TRMC-seq, leading to the discovery of novel tRNA-ac⁴C modification sites, thereby providing a potent sequencing tool for tRNA-ac⁴C research. Our findings expand the repertoire of tRNA ac⁴C modifications and identify a role of tRNA ac⁴C in the regulation of mRNA translation in HNSCC.

Purpose To demonstrate the advantages of non-contrast-enhanced whole-heart coronary magnetic resonance angiography(NCE-CMRA)in evaluating coronary arteries by comparing ultrasonography(US),and to explore the clinical value of NCE-CMRA in the diagnosis of coronary artery lesions of Kawasaki disease(KD)in children.Materials and Methods NCE-CMRA and US imaging data of 41 children with KD from June 2017 to June 2021 who were diagnosed clinically in Lanzhou University Second Hospital were analyzed retrospectively.The display ability of US and NCE-CMRA in coronary arteries were compared.At the same time,the imaging characteristics of NCE-CMRA were analyzed,and the imaging characteristics such as the range and degree of coronary artery lesions displayed by NCE-CMRA were summarized.Results The overall segment display rate of NCE-CMRA in 41 children with KD was 75.6%;the overall segment display rate of US was 46.3%,with statistical difference between the two techniques(χ2=59.04,P<0.001).Regarding the display of the middle and distal segments of coronary arteries,NCE-CMRA had a clear imaging advantage over US(χ2=57.98 and 161.47,P<0.001).In all cases,25 patients(200 segments)had coronary artery lesions,and 94 segments of coronary artery showed different degrees of dilatation,including 8 segments(8.6%)of giant coronary artery aneurysm,35 segments(37.2%)of medium coronary artery aneurysm,and 51 segments(54.2%)of small coronary artery aneurysm or coronary artery dilation.Conclusion NCE-CMRA technology can objectively and accurately display coronary artery in children,and it can specifically evaluate the degree of damage caused by KD.It has important clinical significance in the diagnosis and evaluation of coronary artery lesions in children with KD.

Objective:To assess the predictive value of aspartate aminotransferase-to-alanine amino-transferase ratio (DRR) on overall survival of patients with pancreatic ductal adenocarcinoma (PDAC) who underwent radical pancreaticoduodenectomy.Methods:A retrospective analysis was performed on the clinical data of 137 patients who underwent radical pancreaticoduodenectomy and were diagnosed with PDAC postoperatively at the Chinese PLA General Hospital from January 2015 to December 2020. There were 97 male and 40 female patients, with an average age of (58±10) years old. The patients were grouped according to the optimal survival risk cutoff value of DRR, and the differences in key clinical and pathological indicators between the groups were compared. Kaplan-Meier method was used for survival analysis, and log-rank test was used for comparison of survival rates. Multivariate Cox analysis was performed to evaluate the prognostic factors affecting survival.Results:The 137 PDAC patients were divided into two groups based on the optimal cutoff value of DRR, namely 1.1: DRR≥1.1 was defined as the high-DRR group ( n=29), and DRR<1.1 was defined as the low-DRR group ( n=108). The cumulative survival rate of the low-DRR group was better than that of the high-DRR group, and the difference was statistically significant ( P=0.003). The results of the multivariate Cox regression analysis showed that DRR≥1.1 ( HR=2.485, 95% CI: 1.449-4.261, P=0.001), preoperative biliary drainage ( HR=1.845, 95% CI: 1.030-3.306, P=0.039), lymph node metastasis N2 stage ( HR=2.240, 95% CI: 1.123-4.470, P=0.022), high tumor differentiation ( HR=2.001, 95% CI: 1.279-3.129, P=0.002), and intravascular cancer emboli ( HR=2.240, 95% CI: 1.123-4.470, P=0.022) were risk factors for poor overall survival in PDAC patients who underwent radical pancreaticoduodenectomy. Conclusion:DRR has predictive value for overall survival after surgery in PDAC patients undergoing radical pancreatoduodenectomy. A DRR of 1.1 or greater is a risk factor for poor overall survival after surgery in PDAC patients.
