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 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 diagnostic potential of combining 3.0T magnetic resonance imag-ing(MRI)T2 mapping sequences with serum nesfatin-1 levels for detecting early osteoarthritis(OA)in elderly knees.Methods 97 elderly patients with knee osteoarthritis(OA group)and 52 elderly individuals undergoing physical examinations(control group)were recruited from a hospital between May 2023 and May 2024.Based on X-ray findings,the OA group was further divided into an early-stage subgroup and a non-early-stage subgroup.All participants underwent 3.0T MRI T2 mapping sequence scans to measure the T2 values in the knee cartilage region,and serum nesfatin-1 levels were assessed.Differences in these indicators were compared between groups.Additionally,a receiver operating characteristic(ROC)curve was constructed to evaluate the diagnostic value of these parameters for early-stage knee OA in elderly individuals.Results Among 97 elderly patients with knee OA,35 cases were classified into the early-stage group,and 62 cases were categorized into the non-early-stage group.The T2 values in five cartilage regions of the knee and serum nesfatin-1 levels were significantly higher in the OA group compared to the control group(P<0.05).Moreover,these values were significantly lower in the early-stage group than in the non-early-stage group(P<0.05).The areas under the curve(AUC)for diagnosing early-stage OA using T2 values in knee cartilage regions and serum nesfatin-1 levels ranged from 0.774 to 0.871.Notably,the AUC for combined diagnosis reached 0.939(P<0.05).Conclusion 3.0T MRI using the T2 mapping sequence in combination with serum nesfatin-1 level detection demonstrates high diagnostic value for early OA in elderly patients with knee involvement.

Objective To identify novel biomarkers for predicting the risk of latent tuberculosis infection(LTBI)activation using bio-informatics and machine-learning algorithms and to establish a risk model.Methods The GSE112104 and GSE193777 datasets were obtained from the Gene Expression Omnibus.Differential gene expression and weighted gene co-expression network analyses were per-formed to identify ferroptosis-related differentially expressed genes(FRG-DEGs)associated with LTBI activation.Three machine-learning algorithms,least absolute shrinkage and selection operator,support vector machine-recursive feature elimination,and random forest,were used to identify ferroptosis-related hub genes(FRG-hubs).The reliability of these genes was validated using independent validation datasets and reverse transcription polymerase chain reaction(PCR).A risk model was established using R software.Results In the GSE 112104 dataset,296 genes were upregulated and 1 569 genes were downregulated in active tuberculosis compared to those in LTBI.Among the LTBI progressors,506 genes were upregulated and 1 132 genes were downregulated.Weighted correlation network analysis identified five gene modules,with the blue module showing the strongest correlation with LTBI activation(cor=0.62,P=0.000 04),con-taining 1 340 genes.Intersections with 728 ferroptosis-related genes resulted in eight FRG-DEGs.The machine-learning algorithms iden-tified four FRG-hubs:PLA2G6,GLS2,JUN,and AMN,whose expression decreased with LTBI activation.Reverse transcription PCR con-firmed this trend.A risk model based on these genes yielded an area under the curve of 0.98 to 1.00.Conclusion This study successfully identified novel biomarkers for predicting the risk of LTBI activation and developed an accurate predictive risk model.

Background and Aims:Portal hypertensive colopathy(PHC)is a common complication of portal hypertension in patients with liver cirrhosis.It may lead to gastrointestinal bleeding,yet its underlying pathogenesis remains unclear,and systematic research in China is limited.This study aimed to analyze the colonoscopic features in cirrhotic patients and to explore their associations with relevant clinical factors.Methods:A retrospective analysis was conducted on 99 cirrhotic patients who underwent colonoscopy at Xingtai People's Hospital between July 2020 and December 2024.Colonoscopy,gastroscopy,and clinical data were reviewed.Differences between patients with PHC and those without were compared in terms of sex,Child-Pugh classification,platelet count,presence of ascites,and hepatic encephalopathy.Multivariate logistic regression was used to identify independent risk factors for PHC.Additionally,colorectal lesion detection rates were compared with those of a contemporaneous cohort of 444 participants undergoing national colorectal cancer(CRC)screening at the same center.Results:Among the 105 patients with cirrhosis,the detection rates of PHC,adenomatous polyps,and CRC were 32.32%,28.28%,and 3.03%,respectively,while only 37.37%had no abnormal findings.No serious colonoscopy-related complications were observed.The proportion of males in the PHC group was significantly higher than in the non-PHC group(78.13%vs.50.75%,P=0.009).The PHC group also showed significantly higher rates of Child-Pugh class B/C,and lower platelet count(all P<0.05).There was no statistically significant difference in the incidence of ascites and hepatic encephalopathy between the two groups(P>0.05).Multivariate analysis identified that male gender(OR=3.307,95%CI=1.219-8.971)and Child-Pugh class B/C(OR=2.867,95%CI=1.046-7.861)were independent risk factors for PHC.Compared to the CRC screening cohort,cirrhotic patients had a similar adenoma detection rate(28.28%vs.25.00%,P=0.499),and a slightly higher colorectal cancer detection rate that did not reach statistical significance(3.03%vs.0.68%,P=0.135).Conclusion:Colonoscopy revealed a high rate of abnormalities in cirrhotic patients,with PHC and adenomatous polyps being the most common findings.Routine colonoscopy is recommended for cirrhotic patients without contraindications,especially males,and patients with Child-Pugh class B/C,to facilitate early detection of PHC and precancerous lesions,thereby reducing the risk of lower gastrointestinal bleeding and missed diagnoses of malignancy.

[Purpose]To analyze the changes in the incidence trend of thyroid cancer from 1990 to 2021,and to predict the future incidence from 2022 to 2030.[Methods]We collected data related to the incidence of thyroid cancer among Chinese residents from 1990 to 2021 in the Global Bur-den of Disease 2021(GBD 2021)study,analyzed the trend of thyroid cancer incidence using the Joinpoint regression model,and constructed a Bayesian age-period-cohort(BAPC)model to pre-dict the future incidence of thyroid cancer during the years of 2022-2030,based on the inci-dence data during the years of 1990-2021.[Results]From 1990 to 2021,the age-standardized incidence rate(ASIR)of thyroid cancer in China showed a fluctuating upward trend,and the ASIR of thyroid cancer in China in 2021 was 2.47/105,slightly lower than the global average(2.91/105)in the same year.In 2021,there were significant differences in new cases and incidence rate of thyroid cancer between men and women,with the incidence rate of women being higher than that of men.Among them,the number of new cases in women was 27 915,the crude incidence rate was 4.02/105,and the ASIR was 2.87/105;in men,the number of new cases was 20 189,the crude incidence rate was 2.77/105,and the ASIR was 2.11/105.Between 1990 and 2021,the increase in the number of new cases,the crude incidence rate,and the ASIR of men in China was much larger than that of women.The ASIR of thyroid cancer in both male and female showed an in-creasing trend,while the average annual percentage change(AAPC)in female was lower than that in male.There were significant gender differences in the age-specific incidence rates of thyroid cancer.In 2021,the incidence rate of women was higher than that of men in the Chinese population＜75 years old,whereas the incidence rate of men was higher than that of women in the population≥75 years old.From 1990 to 2021,the incidence rates of the Chinese male population aged 45～59 years old and ≥75 years old increased significantly;and the incidence rate of the Chinese fe-male popu-lation aged 50～74 years old increased significantly.Projections showed that the ASIR of overall,male and female standardized incidence rates in 2030 increased to 2.90/105,2.44/105 and 3.26/105 respectively.[Conclusion]The incidence rate of thyroid cancer in China is on the rise,with the incidence rate of women being higher than that of men,but the incidence rate of men has increased more than that of women,and the gap between the incidence rates is narrow-ing,and the peak age of incidence of men is mostly in the senior age group.

Objective To explore the function of electroacupuncture(EA)on body mass,fasting blood glucose,heat pain threshold,and transient receptor potential vanilloid 4(TRPV4)in the dorsal root ganglia(DRG)of rats with diabetic neuropathic pain(DNP).Methods A DNP rat model was formed by intraperitoneally injecting the animals with STZ.From days 15 to 21,bilateral Zusanli and Kunlun points of the DNP rat model were treated with electroacupuncture once daily for 30 min.We then measured their body mass,fasting blood glucose,and heat pain threshold.The co-expression of TRPV4 and NeuN in the rat L4～L6 DRG was detected by immunofluorescence.The effects of the TRPV4 agonist GSK1016790A on body mass,fasting blood glucose,and the heat pain threshold of DNP rats treated with electroacupuncture were detected.Results After the 7th day,body mass was significantly decreased(P<0.01)and fasting glucose was significantly increased(P<0.01)in the model group compared with the normal group.After the 21st day,compared with the model group,heat pain threshold of the model+electroacupuncture group was significantly higher(P<0.01);the results of co-expression of TRPV4 and NeuN immunofluorescence on rat L4～L6 DRG showed that:the expression of positive cells in the model group was significantly higher(P<0.01)than that in the normal group,the co-expression of TRPV4 and NeuN positive cells in L4～L6 DRG of rats in the model+electroacupuncture group was significantly lower(P<0.01)than that in the model group.The TRPV4 agonist GSK1016790A can reverse the downregulation of thermal pain threshold induced by electroacupuncture in DNP rats(P<0.01).Conclusion Electroacupuncture alleviated the DNP induced by STZ,and its mechanism may involve the inhibition of TRPV4 protein expression in the DRG.

To address the issue of reduced signal quality of photoplethysmography caused by local fluctuation,an approach called locally orthogonal weighted polynomial fitting(LOWPF)is proposed for signal smoothing.After determining the positions of the fluctuation sequences using the forward-backward difference XOR method,weighted polynomial fitting is applied to these sequences,and the fitted values are used to replace the fluctuation sequences to achieve signal smoothing.By constructing orthogonal basis functions,the condition number of the coefficient matrix is reduced,and the stability of the equation system solution for higher-order fitting is improved.Simulation results demonstrate that the smoothed signal's XOR smoothness of the proposed method surpasses that of the moving average algorithm and the empirical mode decomposition reconstruction algorithm.The smoothing results on 241 sets of measured PPG signals show that LOWPF achieves an efficiency of smoothness of 89.10%,significantly higher than the 78.05%of empirical mode decomposition and the 59.13%of the 5-point moving average algorithm.LOWPF has promising application prospects for smoothing signals with significant local fluctuations.

ObjectiveTo analyze the trend of incidence, mortality rate and survival rate of breast cancer among women with registered residence in Xiaoshan District of Hangzhou City in Zhejiang Province from 2014 to 2023, and to provide a basis for improving breast cancer prevention and control strategies. MethodsData on the incidence and mortality of breast cancer among women with registered residence in Xiaoshan District from 2014 to 2023 were collected through Zhejiang Chronic Disease Monitoring and Management System. The crude incidence and mortality rate, as well as the age-standardized incidence and mortality rate using both the 2000 Chinese standard population (abbreviated as “Chinese ASR”) and Segi’s 1960 world standard population (“world ASR”) were calculated. Joinpoint model was employed to analyze the trends in incidence and mortality rate, while R software (version 4.1.1) was used to analyze the 5-year relative survival rate to assess the survival status of breast cancer patients. ResultsFrom 2014 to 2023, the crude incidence rate, the Chinese age-standardized incidence rate (ASIRC) and the world age-standardized incidence rate (ASIRW) of breast cancer among women with registered residence in Xiaoshan District were from 70.00/100 000 to 128.35/100 000, from 52.92/100 000 to 94.29/100 000, and from 40.82/100 000 to 72.07/100 000, respectively, with the corresponding average annual percentage changes (AAPC) of 5.80%, 4.63% and 4.71%, respectively, showing a significant increasing trend over the decade (all P<0.05). The incidence rate of breast cancer among people aged 30‒<40 years old or 50‒<75 years old exhibited a significant increase trend from 2014 to 2023 (all P<0.05). The crude mortality rate of breast cancer in female was from 7.75/100 000 to 12.34/100 000, the ASMRC of breast cancer in female was from 4.62/100 000 to 7.53/100 000, and the ASMRW of breast cancer in female was from 3.58/100 000 to 5.71/100 000, and the AAPC had no statistically significance. However, the mortality rate of breast cancer was increased with age (P<0.001). The 5-year age-standardized relative survival rate of breast cancer in female in Xiaoshan District was significantly higher in the 2016‒2018 period (94.46%) compared to the 2013‒2015 period (91.02%) (P<0.05). ConclusionFrom 2014 to 2023, the annual incidence of breast cancer among women with registered residence in Xiaoshan District of Hangzhou City in Zhejiang Province showed an increasing trend, while the change in mortality rate was not statistically significant. The 5-year survival rate of breast cancer in female was at a high level, indicating notable achievements in comprehensive prevention and control efforts. It is essential to continue to strengthen public awareness campaigns for breast cancer prevention and control, control breast cancer risk factors, actively carry out early diagnosis and treatment of breast cancer among target groups, and improve the quality of life for breast cancer patients.

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.
