Objective:To analyze the 2011-to-2023 baseline data on, and the variations theirin, malignant tumor mortality for the surrounding residents prior to operation of the Jin-Qimen nuclear power plant at Xiangshan county, Zhejiang province, for pursose of providing scientific basis for evaluating the health impacts of nuclear power plant operation.Methods:Data on malignant tumor mortality and population in Xiangshan county from 2011 to 2023 were collected from the Ningzhou Cause of Death Monitoring System and the Ningzhou Public Security Bureau. Crude death rates and standardized rates (China standard population) were calculated. The Joinpoint regression model was used to analyze annual percentage change (APC) and average annual percentage change (AAPC).Results:The average annual malignant tumor mortality from 2011 to 2023 was 212.42 deaths per 100 000 population (age-standardized rate: 133.16 deaths per 100 000 population), with males at 287.41 deaths per 100 000 and females at 135.40 deaths per 100 000 population. The crude mortality exhibited an upward trend (AAPC=1.264%, t=5.07, P<0.05), while the age-standardized rate showed a significant downward trend (AAPC=-2.753%, t=-10.50, P<0.05). Mortality increased with age ( χ2=23 903.91, P<0.05), peaking in the ≥85 age group (1 693.11 per 100 000), and rising trends were observed in males ( χ2=16 982.46, P<0.05) and females ( χ2=7 329.05, P<0.05). Leading causes included lung cancer, liver cancer, gastric cancer, colorectal cancer, and pancreatic cancer. Liver cancer, gastric cancer, and esophageal cancer showed declining trends, whereas prostate cancer increased. Radiation-sensitive tumors (e.g., leukemia, breast cancer, thyroid cancer) displayed no significant trends. Among individuals under the age of 30, leukemia and brain/nervous system cancers predominated; for those aged 30-79, the lung, liver, and gastric cancers were dominant; and for the group aged 80 and above, the lung, gastric, and colorectal cancers were dominant. Malignant tumor mortality increased with distance from the nuclear facility ( χ2=6.90, P<0.05), significantly in males ( χ2=10.42, P<0.05) but not in females ( P>0.05). Leukemia, breast cancer, and thyroid cancer mortality showed no significant trends ( P>0.05). Conclusions:The age-standardized mortality rate for malignant tumors in Xiangshan county demonstrated an overall declining trend, with notable changes in specific cancers. Leukemia, breast cancer, and thyroid cancer mortality remained relatively stable. These baseline findings provide a scientific basis for health impact assessments of nuclear power plants and sustainable nuclear energy development.

Objective: To analyze the trends in incidence and mortality of prostate cancer in Ningbo City, Zhejiang Province, so as to provide insights into the prevention and control of prostate cancer. Methods: Data of the incidence and mortality of prostate cancer in Ningbo City from 2011 to 2023 were collected through Ningbo Chronic Disease Collaborative Management System. The incidence and mortality of prostate cancer were calculated and standardized by the data from the sixth national population census in 2010 and the Segi's world standard population in 1960. The trends in incidence and mortality of prostate cancer were evaluated using average annual percent change (AAPC). Results: A total of 15 411 cases of prostate cancer were reported in Ningbo City from 2011 to 2023, and the crude incidence, Chinese-standardized incidence and world-standardized incidence were 39.62/105, 22.18/105 and 16.49/105, respectively, showing upward trends (AAPC=14.782%, 10.390% and 10.608%, all P<0.05). The Chinese-standardized incidence of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (25.14/105 vs. 19.44/105; AAPC=9.057% and 14.272%, both P<0.05). The crude incidence of prostate cancer in the groups aged 50-<60 years, 60-<70 years, 70-<80 years and ≥80 years showed upward trends (AAPC=11.657%, 14.031%, 10.734% and 5.300%, all P<0.05). A total of 3 739 deaths were reported, and the crude mortality, Chinese-standardized mortality and world-standardized mortality were 9.66/105, 5.23/105 and 3.71/105, respectively, showing upward trends (AAPC=8.458%, 3.620% and 3.602%, all P<0.05). The Chinese-standardized mortality of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (5.35/105 vs. 5.13/105; AAPC=3.183% and 3.962%, both P<0.05). The crude mortality of prostate cancer the groups ageds ≥80 years showed an upward trend (AAPC=7.482%, P<0.05). Conclusions From 2011 to 2023, the incidence and mortality of prostate cancer in Ningbo City showed upward trends. Special attention should be paid to urban residents, and prostate cancer screening should be strengthened among males aged 50 years and older.

Objective: To investigate the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Haishu District, Ningbo City, Zhejiang Province from 2011 to 2022, so as to provide the basis for the formulation of HFMD prevention and control strategies. Methods: Data of HFMD in Haishu District from 2011 to 2022 were collected from Chinese Disease Prevention and Control Information System, and the epidemiological and etiological characteristics were analyzed using a descriptive epidemiological method. The trends in incidence of HFMD and prevalence of positive etiological tests were analyzed using annual percent change (APC). Results: A total of 33 334 cases of HFMD were reported in Haishu District from 2011 to 2022, with an average annual reported incidence of 279.16/105, showing no significant trend (APC=-5.492%, P>0.05). The average annual reported incidence of HFMD was lower after the enterovirus 71 vaccine was launched (from 2017 to 2022) than before (from 2011 to 2016; 219.69/105 vs. 343.70/105, P<0.05). The incidence of HFMD showed seasonal characteristics, with a peak from May to July. There were 19 720 male and 13 614 female cases, with a male-to-female ratio of 1.45∶1. The age of the HFMD cases ranged from 27 days to 63 years old, and the children aged 5 years and below were predominant (30 657 cases, 91.97%). A total of 1 976 specimens of HFMD cases were collected from 2011 to 2022, and 1 509 enterovirus positive specimens were detected, with a positive rate of 76.37%. The positive rates of enterovirus 71 decreased (APC=-32.599%, P<0.05), the positive rates of coxsackievirus A16 increased (APC=9.226%, P<0.05), while the positive rates of other enteroviruses showed no significant change (APC=0.808%, P>0.05). Conclusions The average annual reported incidence of HFMD in Haishu District from 2011 to 2022 decreased after the enterovirus 71 vaccine was launched, with a peak in spring and summer. Children aged 5 years and below were the high-incidence population, and coxsackievirus A16 was the main serotype.

Objective:To investigate the relationship of triglyceride (TG), fasting blood glucose (FPG) and triglyceride glucose product index (TyG) with the incidence of hypertension, and provide basic data for the prevention and treatment of hypertension in the population.Methods:A total of 23 581 individuals who met the research criteria in Jinchang cohort were selected as the research subjects, the Cox proportional hazard model was used to analyze the relationship of TG, FPG, and TyG with the risk of hypertension. A stratified analysis was conducted by sex.Results:After adjusting for confounding factors, compared with the normal TG group, the HR(95% CI) of the elevated TG margin group and the elevated group were 1.16 (1.01-1.34) and 1.49 (1.30-1.70), respectively in the total population. Among men, they were 1.13 (1.01-1.27) and 1.17 (1.06-1.30), and among women, they were 1.05 (0.88-1.26) and 1.06 (0.88-1.28). Compared with the normal FPG group, the HR (95% CI) of the FPG-impaired group were 1.29 (1.13-1.48) in the total population, 1.26 (1.08-1.48) in men and 1.59 (1.14-2.21) in women. Taking the lowest quartile array as a reference, the HR (95% CI) of the highest quartile array of TyG was 1.73 (1.45-2.07) in the total population, 1.32 (1.14-1.53) in men and 1.87 (1.37-2.54) in women. TG, FPG had a nonlinear dose-response relationship with the risk of hypertension, while TyG had a linear correlation with the risk of hypertension. Conclusions:Higher TG, FPG, and TyG levels are independent risk factors for the incidence of hypertension. People with higher TG, FPG and TyG are at high risk for hypertension, to which close attention should be paid in the prevention and treatment of hypertension.

Objective : To compare the clinical effect of the reconstruction of defects of the surgical area with the facial-submental artery island flap (FSAIF) after resection of oral cavity squamous cell carcinoma (OC-SCC) and oropharyngeal squamous cell carcinoma (OP-SCC). Methods: A total of 203 cases of oral cavity squamous cell carcinoma and 72 cases of oropharyngeal squamous cell carcinoma were treated with the FSAIFs. The complications and success rate of the two groups were observed. The swallowing and voice functions of the two groups were evaluated and compared 6 months after the operation. The survival of the two groups was followed up. Results: No significant differences were found in TNM stage, the skin paddle of the flap, the rate of flap failure, or local complications between the OC-SCC and OP-SCC groups (P > 0.05). Significant differences in swallowing and speech outcomes were observed between the groups (P < 0.05). No significant differences were found in survival outcome between the groups after 9-59 months of follow-up. Conclusion FSAIF can be used for reconstructing the defect in oral cavity or oropharynx, but the swallowing function of reconstructing the defect in oropharynx is poor.

Objective: To investigate the incidence and rank of chronic obstructive pulmonary disease and pneumoconiosis to the workers in different occupational positions in Jinchang Cohort. Methods: In January 2014, a cohort of follow-up population in jinchang city was taken as the research object, 17843 individuals among follow-up populations in Jinchang Cohort Study, removed the individuals with chronic obstructive pulmonary disease and pneumoconiosis before 2013, and counted the new incidence individuals diagnosed by the A-Class hospital in Grade III in Jinchang City, Gansu Province, as the investigation objects to investigate the incidence rate & rank of chronic obstructive pulmonary disease and pneumoconiosis. The statistical significance was tested by chi-square test. Results: The 2-year incidence rate of Chronic Obstructive Pulmonary Disease and Pneumoconiosis in the population of Jinchang Cohort Study were 11.60‰, 13.51‰ for male and 8.46‰ for female. the ranks of 2-year incidence rates of chronic bronchitis, emphysema, pneumoconiosis and other phenotypes of chronic obstructive pulmonary disease were 7.06‰、3.42‰、0.84‰、0.34‰, respectively. Incidence rate of chronic bronchitis among administrators and executive staffs were 10.45‰; incidence rate of chronic bronchitis among service staffs were 10.45‰; incidence rate of pneumoconiosis among mining staffs were 3.44‰. Conclusion The first incidence rank of chronic obstructive pulmonary disease and pneumoconiosis in Jinchang cohort is chronic bronchitis, and the risk factors are smoking and occupational exposure.

Objective To investigate the relationship between changes in the liver computed tomography (CT) images and the postmortem interval (PMI) of rabbits 129 h after their death due to hemorrhagic shock. Methods CT scanning was used to investigate the hemorrhagic shock death model in 23 rabbits to identify the postmortem cerebral changes from 0 h to 129 h after death. Results The liver or lumbar area in the liver window showed the following characteristic changes: from unchanged, to rapid shrinkage, to slow shrinkage; the mean CT values of the liver initially increased and subsequently decreased. The regression equations for the relationship between the two indices and PMI were established by surgery, and they all had statistical significance (P ＜ 0. 01). Conclusion CT scanning can accurately show changes in the rabbit liver after death. The mean CT value of the liver tissue is more sensitive for inferring early PMI. Furthermore, the liver area/lumbar area ratio parameters are more sensitive for inferring mid-late PMI.

Bipolar disorder (BD), characterized by recurrent mood swings between depression and mania, is a highly heritable and devastating mental illness with poorly defined pathophysiology. Recent genome-wide molecular genetic studies have identified several protein-coding genes and microRNAs (miRNAs) significantly associated with BD. Notably, some of the proteins expressed from BD-associated genes function in neuronal synapses, suggesting that abnormalities in synaptic function could be one of the key pathogenic mechanisms of BD. In contrast, however, the role of BD-associated miRNAs in disease pathogenesis remains largely unknown, mainly because of a lack of understanding about their target mRNAs and pathways in neurons. To address this problem, in this study, we focused on a recently identified BD-associated but uncharacterized miRNA, miR-1908-5p. We identified and validated its novel target genes including DLGAP4, GRIN1, STX1A, CLSTN1 and GRM4, which all function in neuronal glutamatergic synapses. Moreover, bioinformatic analyses of human brain expression profiles revealed that the expression levels of miR-1908-5p and its synaptic target genes show an inverse-correlation in many brain regions. In our preliminary experiments, the expression of miR-1908-5p was increased after chronic treatment with valproate but not lithium in control human neural progenitor cells. In contrast, it was decreased by valproate in neural progenitor cells derived from dermal fibroblasts of a BD subject. Together, our results provide new insights into the potential role of miR-1908-5p in the pathogenesis of BD and also propose a hypothesis that neuronal synapses could be a key converging pathway of some BD-associated protein-coding genes and miRNAs.
