Abstract
Objective: To investigate the characteristics and trends of spontaneous subarachnoid hemorrhage (SAH) in Shandong province. Methods: In this study, SAH incidence data of residents from 2012 to 2021 were collected from the chronic disease monitoring information management system of Shandong province, including the basic information of outpatient, emergency or inpatient cases and out-of-hospital deaths (name, gender, ID number, address, etc.) and disease diagnosis information (disease diagnosis, date of onset, date of diagnosis, etc.). The crude incidence rate and age-standardized incidence rate were used as indicators to describe the incidence of SAH in different gender, age groups and regions (urban and rural areas). Joinpoint regression was used to analyze the variation of incidence rate and age by year. The rate difference decomposition method was used to estimate the contribution of population aging to the increase of SAH incidence. Global and local spatial autocorrelation analysis was performed using DeoDa 1.12 software. Results: From 2012 to 2021, a total of 11 629 cases of SAH were reported from 19 provincial monitoring sites in Shandong province. Among them, 54.11% (6 293 cases) were female and 91.87% (10 684 cases) were≥45 years old. The reported crude incidence rate increased from 5.26/100 000 to 9.50/100 000, with an average annual increase of 7.75% (Ztrend=7.30, Ptrend<0.001), and the standardized incidence rate also showed an upward trend (Ztrend=3.92, Ptrend=0.004). The crude incidence rate of women was higher than that of men in all years (all P values<0.05), and the standardized incidence rate of women was higher than that of men in all years except in 2012 and 2021 (all P values<0.05). In 2012, the crude incidence and standardized incidence of urban residents were lower than those in rural areas (P<0.05); from 2013 to 2017, the urban incidence was higher than that in rural areas; and after 2018, the rural incidence exceeded the urban incidence again (all P values<0.05). The median age of onset of SAH increased from 61.9 years in 2012 to 67.2 years in 2021. The age of onset of SAH in men was lower than that in women in all years (all P<0.05), and there was no significant difference between urban and rural residents in most years (P>0.05). The incidence of SAH increased with age (Ptrend<0.001), with a low incidence reported in residents aged<45 years and a rapid increase in residents aged≥45 years. According to the seasonal decomposition, the incidence of SAH had three small peaks in January, March to May and October to November. From 2013 to 2021, the contribution of aging population to the increase of crude incidence of SAH increased from 27.86% to 43.68%. The global spatial autocorrelation analysis showed that the incidence of SAH was in an obvious spatial aggregation distribution (Moran's I>0, P<0.05). Local spatial autocorrelation analysis showed that the counties with high incidence were mainly concentrated in Dezhou City in northwest Shandong Province and Heze city in southwest Shandong province. Conclusions: The crude incidence rate of SAH in Shandong province is increasing, with spatial clustering and seasonal clustering. Residents aged 45 years and older, female residents, and rural residents are at high risk of developing SAH, so targeted prevention and control measures should be taken for high-incidence seasons, high-risk groups, and high-incidence clustered areas.

Abstract
Objective: To understand the characteristics and trends of acute myocardial infarction (AMI) in Shandong Province and to provide evidence for formulating prevention and control strategies. Methods: Data were derived from the AMI incidence reports of Shandong Province's Chronic Disease Surveillance Information Management System in 2012-2021. The crude and standardized incidence rates were used as indicators to describe the incidence level of AMI. Joinpoint regression analysis was used to analyze the trends in the incidence and age of onset over the years. The contribution of population aging to the increase in AMI incidence was assessed using the rate difference decomposition method. The incidence of AMI in each district (county) in Shandong Province was visualized using ArcGIS 10.8 software, and global and local spatial autocorrelation analysis was performed using DeoDa 1.12 software. Results: From 2012 to 2021, 198 233 cases of AMI were reported from 19 provincial monitoring sites in Shandong Province, of which 53.13% were males and 97.12% were ≥45 years old. The reported crude incidence increased from 90.12 per 100 000 in 2012 to 176.54 per 100 000 in 2021, with an average annual increase of 7.01% (Z=7.35, P<0.001). There was no significant upward trend in standardized incidence (Z=1.64, P=0.140), but the standardized incidence of male residents showed an increasing trend (Z=2.76, P=0.028). Before 2014, the reported crude incidence of males was similar to that of females, but after 2014, the reported crude incidence of males was continuously higher than that of females. However, males' standardized incidence was higher than females in all years. Both crude and standardized incidence rates were higher in rural residents than in urban areas. The median onset of AMI increased from 71.6 years old in 2012 to 73.5 years old in 2021. The median age of onset in males was lower than that in females in all years, and in most years, the median age of onset in urban residents was lower than that in rural residents. The incidence of AMI in males showed a trend in younger age groups. According to the seasonal decomposition, the incidence peak of AMI was in January, and the trough was in September. The contribution of aging population to the increase in crude incidence of AMI increased from 8.63% in 2013 to 52.58% in 2021. The global spatial autocorrelation analysis showed that the incidence of AMI presented an obvious spatial clustering distribution. Local spatial autocorrelation analysis found that the high-incidence areas (counties) were mainly concentrated in Liaocheng City and Dezhou City in the northwest region of Shandong Province and Heze City in the southwest. Conclusions: The incidence of AMI among residents in Shandong Province was rising, with spatial clustering and seasonal clustering characteristics. People aged 45 years and older, male residents, and rural residents were at high risk of developing AMI. There was a certain trend of younger age at onset among men. Targeted prevention and control measures should be taken for high-incidence seasons, high-risk groups, and high-incidence clustering areas in northwestern Shandong Province.

Abstract
INTRODUCTION Dietary factors may play an important role in periodontal health. However, current evidence from observational studies remains inconclusive. OBJECTIVE This study aimed to investigate the causal relationships between dietary exposures and periodontal disease risks using Mendelian randomization analysis. METHODS Large-scale genome-wide association study summary statistics for 20 dietary factors were obtained from the MRC-IEU consortium. Multivariable and univariable 2-sample Mendelian randomization analyses were performed to assess the causal effects of each dietary exposure on 6 periodontal outcomes, including gingivitis and periodontitis. RESULTS Genetically predicted higher dried fruit intake was significantly associated with reduced risks of acute gingivitis (odds ratio [OR]: 0.02; 95% confidence interval [CI]: 0.00-0.42; P = 0.01) and bleeding gums (OR: 0.96; 95% CI: 0.93-0.99; P = 0.01). Higher fresh fruit and water intake showed protective effects against chronic gingivitis (OR: 0.18; 95% CI: 0.04-0.91; P = 0.04 and OR: 0.15; 95% CI: 0.04-0.53; P = 0.00) and bleeding gums (OR: 0.95; 95% CI: 0.92-0.981; P = 0.00 and OR: 0.98; 95% CI: 0.96-0.99; P = 0.02). Alcohol intake frequency and processed meat intake were risk factors for bleeding gums (OR: 1.01; 95% CI: 1.00-1.02; P = 0.01 and OR: 1.05; 95% CI: 1.01-1.08; P = 0.00) and painful gums (OR: 1.01; 95% CI: 1.00-1.01; P = 0.00 and OR: 1.02; 95% CI: 1.01-1.03; P = 0.00). Most of the causal relationships between genetic predisposition to the specified dietary factors and periodontal diseases remained statistically significant (P < 0.05) after adjusting for genetic risks associated with dentures, smoking, and type 2 diabetes in multivariable Mendelian randomization models. CONCLUSIONS The findings suggest potential protective effects of higher fruit and water intake against gingivitis and other periodontal problems, while alcohol and processed meat intake may increase the risks of periodontal disease. Our study provides preliminary causal evidence on the effects of diet on periodontal health and could inform prevention strategies targeting dietary habits to improve oral health. KNOWLEDGE TRANSFER STATEMENT This study suggests that fruit and water intake may protect against periodontal disease, while alcohol and processed meats increase risk, informing dietary guidelines to improve oral health.

Abstract
Objective: To analyze the trend of incidence and mortality of thyroid cancer and estimate its age-period-cohort effect in Shandong Province from 2012 to 2022. Methods: The Joinpoint regression was used to analyze the trend of incidence and mortality of thyroid cancer and calculate the average annual percentage change (AAPC) based on the data on thyroid cancer from 2012 to 2022. The age-period-cohort model was used to analyze the age-effect, time-effect and cohort-effect of thyroid cancer risk in the population aged over 20 years. Results: From 2012 to 2022, the incidence of thyroid cancer in Shandong province showed a significant upward trend, with an AAPC of 21.68% (95%CI: 19.14%-24.27%, P<0.001). The incidence of females was higher than that of males, and the incidence of urban areas was higher than that of rural areas. The trend of thyroid cancer mortality was relatively stable with an AAPC of -3.04% (95%CI:-8.81%-3.09%, P=0.323). The age effect of incidence increased with age before 60 years old and decreased with age after 60 years old. The incidence peaked in the age group of 55-59. The period effect increased with time. The cohort effect showed that the cohort born before 1957 had a downward trend over time, while the cohort born after 1957 had an upward trend. Conclusion: The incidence of thyroid cancer in Shandong shows a rising trend from 2012 to 2022. Age is an important factor affecting the risk of thyroid cancer. The mortality of thyroid cancer remains stable.

Abstract
Objective: To evaluate the reliability and validity of the Chinese Criteria of Health Scale for the elderly people. Methods: A cross-sectional study was performed among older adults of Meiyuan Community in Haidian District, Beijing and Nanwangkong Village in Qingzhou City,Shandong Province during July 2021. Using a cluster sampling method, totally 667 elderly people were investigated by face-to-face interview, using the scale which was formulated after two rounds of the Delphi method and pilot study. The overall scale includes physical health, mental health and social health subscales, including 9, 52 and 15 items, respectively. Four weeks after the survey, 56 elderly people were randomly selected and repeated the survey with the same method. The test-retest reliability, split-half reliability and internal consistency reliability of the scale were evaluated, and the validity was evaluated at the same time, including construct validity and content validity. Results: A total of 710 questionnaires were distributed and 667 valid questionnaires were obtained, with a total effective rate of 93.94%. The score of the overall scale was 79.79±16.22, the scores of the physical health, mental health, social health sub-scores were 41.64±9.76, 26.82±3.92 and 11.34±5.19, respectively. The scale had excellent reliability. In the test-retest reliability, the intraclass correlation coefficient (ICC) of the overall scale and each subscale were 0.766-0.861, and the weighted Kappa values were 0.762-0.817. The Spearman-Brown coefficient of the overall scale and each subscale in the split-half reliability were 0.722-0.855 (all P<0.001). The Cronbach's α coefficients of the overall scale of internal consistency reliability and each subscale were 0.748-0.899, and the Cronbach's α coefficients of each dimension were from 0.709 to 0.963(all P<0.001). At the same time, the scale had good construct validity and content validity. The correlation coefficients between the score of each dimension and its sub-scale were larger, from 0.641 to 0.873 (all P<0.05). The cumulative variance contribution rates of the scale and three subscales were all more than 50% of the approved standard. A total of 11 common factors were extracted, and all the load values of each item on the corresponding factors were ≥0.04. Conclusion: The Chinese Criteria of Health Scale for the elderly people has good validity and excellent reliability. It can be used as a basis for the scientific division of the health status of the elderly, the formulation of relevant policies by the government and the provision of appropriate health services for the elderly.

Abstract
The clinical data and follow-up results of 27 paraspinoid aneurysms treated by Willis covered stent (WCS) in Department of Neurosurgery, Army Medical University from May 2014 to January 2021 were retrospectively analyzed. Among them, 17 cases (63.0%) were treated with WCS alone, and 10 cases (37.0%) were assisted with coiling embolization. During the follow-up, postoperative internal leakage occurred in 2 patients(7%), of which 1(type Ⅰ) wasself-healing and the other 1 (type Ⅲ) was cured by WCS implantation again. The remaining patients had no aneurysm recurrence, unobstructed parent artery, stent displacement and internal stenosis. 92.6% (25/27) of the improved mRS scores were good. WCS is a safe and effective method for the treatment of parabedinal aneurysms.

Abstract
Objective: To analyze the association between waist-to-height ratio and the overall and type specific incidence of stroke in adults in China. Methods: A total of 36 632 people were selected from 60 surveillance sites (25 in urban area and 35 in rural area) in China Chronic Disease Surveillance Project in 2010. The China Chronic Disease Surveillance Project data in 2010 were used as baseline data. A total of 27 762 people were followed up from 2016 to 2017. Cox proportional risk regression model was used to analyze the risk ratio of waist-to-height ratio for the overall and type specific incidence of stroke. Subgroup analyses were performed based on baseline characteristics such as age and sex, and sensitivity analysis was performed by excluding those who died and those with diabetes at baseline survey. Results: A total of 27 112 subjects were included in the stroke analysis, and 1 333 stroke events were observed. A total of 26 907 subjects were included in the ischemic stroke analysis, and 1 128 ischemic stroke events were observed. A total of 25 984 subjects were included in the hemorrhagic stroke analysis, and 205 cases of hemorrhagic stroke were observed. After adjusting for relevant confounders and taking group with waist-to-height ratio of 0-0.45 as a reference, the stroke analysis indicated that in groups with waist-to-height ratio of 0.46-0.49, 0.50-0.54 and ≥0.55 the risk for stroke increased by 21% (HR=1.21, 95%CI:1.00-1.46), 26% (HR=1.26, 95%CI:1.04-1.53) and 60% (HR=1.60, 95%CI:1.29-1.99) respectively. Subgroup analysis revealed that age specific waist-to-height ratio had modification effect on the risk for stroke (interaction P=0.001). Ischemic stroke analysis indicated that in groups with waist-to-height ratio of 0.46-0.49, 0.50-0.54 and ≥0.55 the risk for ischemic stroke increased by 30% (HR=1.30, 95%CI: 1.05-1.60), 33% (HR=1.33, 95%CI: 1.07-1.64) and 61% (HR=1.61, 95%CI: 1.26-2.05) respectively. Subgroup analysis revealed that age specific waist-to-height ratio had modification effect on the risk for ischemic stroke (interaction P=0.024). Hemorrhagic stroke analysis indicated that in group with waist-to-height ratio of ≥0.55 the risk for hemorrhagic stroke increased by 73% (HR=1.73, 95%CI: 1.02-2.94), but the differences in the risk increase in groups with waist-to-height ratio of 0.46-0.49 and 0.50-0.54 were not significant. The sensitivity analysis showed no changes. Conclusions: In the prevention and control of stroke by body weight control, it is necessary to take waist to height ratio as one of the indicators of body weight control. Particular attention needed to be paid to the people aged <50 years with waist-to-height ratio of ≥0.55 as well as those with waist-to-height ratio of <0.5 (i.e., 0.46-0.49).

Abstract
Objective: To study the specific alignment and structure of cancellous bone within the talus in order to understand the mechanism of force transmission within the bone and to provide some theoretical basis for the repositioning of talar fractures and the design of prostheses. Methods: In January 2020, a total of 40 adult talar bone specimens were scanned by Micro-CT in 20 pairs obtained from the Department of Orthopedics of Tianjin Hospital. The bone volume fraction, bone surface area fraction, trabecular thickness, number of trabeculae, trabecular pattern factor of the head, neck and body of the talus were calculated, and the differences in each parameter were compared between different parts of the same side and different sides of the same part, respectively. The talus was cut into 2 mm thick slices in the coronal, sagittal and horizontal planes using a hard tissue slicer, and the slices were then scanned using high-resolution X-rays to describe the bone structure. Results: There were no statistically significant differences between the medial and lateral talar and right and left side in lateral trabecular bone volume fraction, bone surface area fraction, trabecular thickness, trabecular number, trabecular pattern factors (all P>0.05). The number of trabeculae in the talar head, neck and body was 1.608±0.150, 1.639±0.142 and 1.749±0.159, respectively; trabecular thickness (μm) in the talar head, neck and body was 0.378±0.054, 0.370±0.053 and 0.331±0.062, respectively; and the trabecular pattern factors (mm-1) in the talar head, neck and body was -0.407±0.699, -0.478±0.848 and -1.029±0.851, respectively. There were significant differences between talar head, neck and the talar body trabeculae in terms of the number of trabeculae, trabecular thickness,trabecular pattern factor parameters(all P<0.05). The structure of the talar body trabeculae was found to consist of plate trabeculae arranged vertically parallel to each other in the coronal, sagittal and horizontal planes. The talar neck trabeculae were twisted, external-superior to internal-inferior reticular plate structure that travelled posteriorly and anteriorly, and the talar head trabeculae consisted of similarly parallel aligned semi-arc-shaped external-superior and internal-inferior trabeculae. Conclusion: The talar trabeculae are clearly directional and functional, so anatomical reduction should be achieved after the fracture; at the same time, the design of the talar prosthesis should take into account the stress distribution and direction of the prosthesis during walking and standing.

Abstract
Objective: To explore the relationship between body mass index (BMI), waist circumference (WC) and the risk for ischemic stroke in adults in China. Methods: A total of 36 632 adults were selected from 60 surveillance areas (25 urban surveillance areas and 35 rural surveillance areas) in China Chronic Disease Surveillance Project in 2010 for a follow up study from 2016 to 2017 based on the baseline data in 2010. The follow up was completed for 27 762 adults. Cox proportional hazard regression model was used to analyze the association of body mass index and waist circumference with the risk for ischemic stroke in different populations. The death and hypercholesterolemia cases were excluded by sensitivity analysis. Results: A total of 26 907 adults were included in the analysis. During the follow up period, 1 128 ischemic stroke events were observed (491 in men and 637 in women). After adjusting the related confounding factors and taking normal BMI/normal WC group as the reference, the risk for ischemic stroke increased by 50% in normal BMI/abdominal obesity group (HR=1.50, 95%CI:1.07-2.08), 51% in overweight/abdominal obesity group (HR=1.51, 95%CI:1.20-1.91), 46% in obesity/abdominal obesity group (HR=1.46, 95%CI:1.09-1.96), and 63% in normal BMI/abdominal obesity group (HR=1.63, 95%CI:1.12-2.38), 56% in overweight/abdominal obesity group (HR=1.56, 95%CI: 1.20-2.03) and 45% in obesity/abdominal obesity group (HR=1.45, 95%CI: 1.05-2.01) respectively in men and in men with CVD risk factors. There was no increased risks in the overweight/normal WC group. The risk increased by 40% in overweight/abdominal obesity group (HR=1.40, 95%CI:1.15-1.72) and 46% in obesity/abdominal obesity group (HR=1.46, 95%CI:1.16-1.83), and 35% in overweight/abdominal obesity group (HR=1.35, 95%CI:1.08-1.69) and 30% in obesity/abdominal obesity group (HR=1.30, 95%CI:1.01-1.67) respectively in women and women with CVD risk factors. There were no risk increases in overweight/normal WC group and normal BMI/abdominal obesity group. Sensitivity analysis results showed no change. Conclusion: Overweight/obesity with abdominal obesity or abdominal obesity alone could increase the risk for stroke in men, and overweight/obesity with abdominal obesity could increase the risk for ischemic stroke in women; suggesting that BMI and WC should be used jointly to evaluate obesity in population for weight control to prevent ischemic stroke.

Abstract
Objective: To investigate the sodium intake, potassium intake, sodium- potassium ratio and influencing factors of family cooks and members in six regions of China. Methods: Using the multistage random sampling method, a total of 1 576 family cooks and their family members were recruited from 6 regions in China. Questionnaire survey and physical examination were conducted to collect basic information. 24 h urine was collected to test 24 h urinary sodium and potassium levels. Results: After excluding unqualified urine samples, a total of 1 530 people were included in the study. For all participants, 24 h urine sodium value was (4.39±1.93) g, 24 h urine potassium value was (1.59±0.62) g and sodium-potassium ratio was 5.02±2.18. 24 h urinary sodium was negatively correlated with age, female, junior high school education or above, and annual family income (P<0.05), and positively correlated with perceived salty taste, BMI and SBP (P<0.05). The 24 h urine potassium value was negatively correlated with eating out almost everyday (P<0.05), but positively correlated with BMI and unwillingness to reduct salt (P<0.05). The sodium-potassium ratio was negatively correlated with age, female and junior high school education or above annual family income (P<0.05), and positively correlated with perceived salty taste, SBP and eating out 3-5 d/week (P<0.05). Conclusions: The 24 h urinary sodium value and sodium potassium ratio of family cooks and family members in six regions of China are still at high level, while the 24 h urine potassium value is low, with multiple factors. Therefore, it is necessary to carry out long-term comprehensive salt reduction intervention for family cooks and their members.

Abstract
Objective: To investigate the clinical features and effect of prognostic factors in patients with different pathological types of non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis. Methods: We collected and analyzed the clinical data of 89 patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis who were treated at Huadong Hospital from March 2013 to May 2020. The data were analyzed via log-rank and Cox multivariate analyses. Results: The median overall survival time of the 89 cases was 10.2 months. Patients with B-cell lymphoma-associated hemophagocytic lymphohistiocytosis did not reach the median overall survival time. The median overall survival times of T-cell lymphoma-associated hemophagocytic lymphohistiocytosis and NK-cell lymphoma-associated hemophagocytic lymphohistiocytosis were 10.2 and 3.0 months, respectively. The pathological type of non-Hodgkin lymphoma (OS: P=0041, PFS: P=0.015) , ECOG score ≥ 3 (OS: P=0.031, PFS: P=0.030) , hematopoietic stem cell transplantation (OS: P=0.005, PFS: P=0.040) , lymphadenopathy (OS: P=0.007, PFS: P=0.012) , and splenomegaly (OS: P=0.276, PFS: P=0.324) were related to the overall survival and progression-free survival of patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis. Splenectomy could improve the prognosis of patients with lymphoma-associated hemophagocytic lymphohistiocytosis, especially T-cell lymphoma-associated hemophagocytic lymphohistiocytosis. Conclusion: The clinical characteristics of patients with different pathological types of non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis were similar but were different in the overall survival rate and the effect of prognostic factors. We suggested that patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis should receive more than combined chemotherapy. To improve the prognosis and survival rate of patients, those with B-cell lymphoma-associated hemophagocytic lymphohistiocytosis and NK-cell lymphoma-associated hemophagocytic lymphohistiocytosis promptly require hematopoietic stem cell transplantation. Moreover, patients with T-cell lymphoma-associated hemophagocytic lymphohistiocytosis should consider splenectomy.

Abstract
Objective: To explore the influence of characteristics of green space on blood pressure control. Methods: Hypertensive patients who were managed by community health centers for one year and aged 35 years old and above were selected as the study subjects in Shenzhen. Multi-stage random sampling method was applied to select a representative sample of 1 200 patients. A total of 1 116 valid questionnaires were collected, with a response rate of 93.0%. From November 2019 to January 2020, well-structured questionnaire, physical examination and laboratory biochemical test were applied for information collection among the 1 116 participants. Binary logistic regression model was used to analyze the relationship between characteristics of green space and blood pressure control. Results: The rate of blood pressure control was 67.8%. Results of binary logistic regression analysis showed that after adjusting confounding factors, health supporting elements, such as fitness areas (OR=1.678, 95%CI:1.231-2.288), collective exercise venues(OR=1.373, 95%CI:1.020-1.848), health knowledge promotion areas (OR=1.416, 95%CI: 1.049-1.911) in green space, were significantly correlated with blood pressure control. Green space safetiness (OR=1.010, 95%CI: 1.000-1.019), comfortableness (OR=1.011, 95%CI: 1.001-1.021) and maintenance status (OR=1.011, 95%CI: 1.001-1.021) also played a role. The rate of blood control among patients with exclusive green space was higher than that of patients without exclusive green space (OR=1.333, 95%CI: 1.009-1.762). Conclusion: Health supporting elements, safety, comfort, maintenance of green space and exclusive green space play an important role in blood pressure controlling.

Abstract
OBJECTIVE Dysregulation of long non-coding RNAs (lncRNAs) is being found to have relevance to human cancers, including prostate cancer (PCa). Taurine-upregulated gene 1 (TUG1) has been demonstrated to have a potential oncogenic role in PCa. Then the aim of this study was to investigate the molecular mechanisms of TUG1 on PCa progression. PATIENTS AND METHODS The expression levels of TUG1, YES proto-oncogene 1 (YES1) mRNA and miR-128-3p were assessed using quantitative real-time polymerase chain reaction. Cell proliferation ability, apoptosis, and migration and invasion capacities were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, flow cytometry and transwell assay, respectively. Western blot analysis was employed to evaluate the indicated proteins levels. The interaction between miR-128-3p and TUG1 or YES1 was determined using the Dual-Luciferase reporter assay. In vivo assay was used to observe the effect of TUG1 on tumor growth in vivo. RESULTS Our data indicated that TUG1 was upregulated in PCa tissues and cells and predicted poor prognosis. TUG1 knockdown weakened PCa cell proliferation, migration, invasion, epithelial-mesenchymal transition (EMT), and accelerated cell apoptosis in vitro. Mechanistically, TUG1 directly interacted with miR-128-3p and miR-128-3p mediated the regulatory effects of TUG1 depletion on PCa cell progression. YES1 was a direct target of miR-128-3p and TUG1 modulated YES1 expression by sponging miR-128-3p. Moreover, TUG1 silencing repressed PCa cell progression in vitro through YES1. Additionally, TUG1 silencing mitigated tumor growth in vivo. CONCLUSIONS Our study suggested that TUG1 silencing retarded PCa cell progression in vitro and tumor growth in vivo through miR-128-3p/YES1 axis, showing that targeting TUG1 might be a novel therapeutic strategy for PCa management.

Abstract
Objective: To assess the relationship between body mass index (BMI) and death risk of cardiovascular disease (CVD) in rural male population. Methods: 22 282 men aged 40 years older in Tanghe county and Fenghuang county from the cohort of the "Prospective Study on Adult Behavior and Health Risk Factors in China" were selected as subjects of this study. Cox regression model was used to calculate the hazard ratios (HRs) of the death of CVD during the follow-up period with different BMI groups at baseline. Results: The average follow-up period in the two counties was (19.1±8.7) years and 10 828 (48.6%) people died during the follow-up period. 4 504 deaths were attributed to CVD. Among the deaths of CVD, 1 279 cases died of ischemic heart disease (IHD), ischemic stroke (IS) died in 1 201, cases died of died of 1 317 hemorrhagic stroke (HS), other 707 cases. Compared to population with BMI<18 kg/m(2), Cox regression model (adjusting factors of region, age, nationality, education level, occupation, smoking, drinking, blood pressure, blood pressure, etc.) showed that people with BMI between 20-22 kg/m(2) had the lowest risk of CVD death (HR=0.95, 95%CI: 0.83-1.09). But the difference was not statistically significant among each BMI group (P>0.05). The risk of IHD death was the lowest in the population with BMI between 20-22 kg/m(2) (P<0.05) (HR=0.64, 95%CI: 0.52-0.80). There was no statistically significant difference between the risk of IHD death in the population with BMI≥24 kg/m(2) and that in the population with BMI<18 kg/m(2) (P>0.05). There was no statistically significant difference between the risk of IS death and BMI (P>0.05). The death risk of HS in the population with BMI between 18-24 kg/m(2) was higher than that in the population with BMI<18 kg/m(2) (P<0.05). The death risk of the population with BMI between 26-28 kg/m(2) was the highest (HR=1.88, 95%CI:1.18-2.99). Conclusions: The mortality risk of CVD and IHD was the lowest in lean or normal weight group, and HS was higher in overweight group. Maintaining a reasonable weight can reduce the risk of death in patients with CVD.

Abstract
Objective: To explore the relationship between sedentary time and the incidence of type 2 diabetes in adults in China. Methods: Data collected from the Chinese Chronic Disease and Risk Factor Surveillance (CCDRFS) in 2010 were used as baseline data. Eight provinces where CCDRFS were conducted in 2010 were selected, and two surveillance spots (one in urban area and another one in rural area) of each provinces were further selected for the follow-up studies. After excluding diagnosed diabetes patients according to baseline data, a total of 8 625 of subjects were recruited as participants. In the follow up carried out from 2016 to 2017, a total of 5 991 people received complete follow up. Cox proportional hazards models were used to analyze the relationship between sedentary time and the incidence of type 2 diabetes, and subgroup analysis was conducted based on variables such as gender, geographic area, and urban area or rural areas. Results: A total of 5 782 subjects were included in final analysis. During an average 6.4 years of follow up (36 927.0 person-years), 592 participants developed type 2 diabetes, the incidence rate was 16.0 per 1 000 person years. Multivariate Cox regression analysis showed that after adjustment for possible confounders, compared with the 0.0-h/d group, the risk of diabetes incidence increased by 33% (HR=1.33, 95%CI: 1.05-1.68) for those who had sedentary time for more than 6.0 h every day. The subgroup analysis showed that the significant association was only observed in those who were men, current smokers, central obese, had family history of diabetes, had rural residency, and lived in eastern and central areas of China. Conclusions: Longer sedentary time can increase the risk of type 2 diabetes. Lifestyle intervention should be strengthened to reduce sedentary time, especially for people who had sedentary time for more than 6.0 h every day.

Abstract
OBJECTIVE Recently, long non-coding RNAs (lncRNAs) have attracted much attention for their roles in tumor progression. The aim of this study was to investigate the specific role of lncRNA MNX1-AS1 in the development of gastric cancer (GC), and to explore the underlying mechanism. PATIENTS AND METHODS MNX1-AS1 expression in both GC cells and tissue samples was detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR). Moreover, the relationship between MNX1-AS1 expression and the overall survival rate of GC patients was explored. Furthermore, wound healing assay and transwell assay were conducted. In addition, the underlying mechanism of MNX1-AS1 in GC was explored by performing RT-qPCR and Western blot assay. RESULTS MNX1-AS1 expression in GC samples was significantly higher than that of the corresponding normal tissues. Meanwhile, MNX1-AS1 expression was associated with the overall survival time of GC patient. Moreover, the migration and invasion of GC cells were markedly promoted after MNX1-AS1 overexpression in vitro. The mRNA and protein expressions of CDKN1A were remarkably down-regulated after MNX1-AS1 overexpression. Furthermore, the expression level of CDKN1A was negatively correlated with the expression of MNX1-AS1 in GC tissues. CONCLUSIONS Our results suggested that MNX1-AS1 could enhance the metastasis and invasion of GC cells via suppressing CDKN1A. Furthermore, MNX1-AS1 might be a potential therapeutic target for GC.

Abstract
OBJECTIVE Recent researches have proved that long non-coding RNAs (lncRNAs) has an important role in many diseases. In this research, lncRNA AK027294 was explored to identify how it functions in the development of gastric cancer (GC). PATIENTS AND METHODS Real Time-quantitative-Polymerase Chain Reaction (RT-qPCR) was utilized to detect AK027294 expression in GC patients. Then, MTT assay, colony formation assay, and EdU incorporation assay were performed to identify its function in GC cells. Furthermore, the potential mechanism was also explored using mechanism assays. RESULTS AK027294 expression level was significantly higher in GC tissue samples and cell lines. Results of MTT assay, colony formation assay, and EdU incorporation assay showed that cell proliferation was inhibited through the silence of AK027294 in GC cells, while cell proliferation was promoted through overexpression of AK027294 in GC cells. Furthermore, the expression of PCNA was downregulated via silence of AK027294 in GC cells, while the expression of PCNA was upregulated via overexpression of AK027294 in GC cells. The correlation analysis showed that PCNA expression was positively correlated with AK027294 expression in GC tissues. CONCLUSIONS Our results suggest that AK027294 could enhance cell proliferation of GC cells by upregulating PCNA and might be applied as a novel target for therapy of GC.

Abstract
OBJECTIVE Evidence has demonstrated that miR-630 is involved in multiple processes in cancer development and progression. However, the exact functions of miR-630 in papillary thyroid carcinoma (PTC) and the underlying mechanisms remain undefined. Therefore, the aims of the present study were to investigate the role and potential mechanism of miR-630 in tumorigenicity of PTC. PATIENTS AND METHODS Microarrays were used to analyze the differentially expressed miRNAs in PTC tissues. Expression of miR-630 in PTC tissues and cell lines were determined by a qRT-PCR assay. CCK-8 assays, clonogenic survival assays, cell apoptosis analysis, wound healing assays and transwell invasion assays were used to examine the tumorigenesis function of miR-630 in vitro. Protein expression of signaling pathways was determined by using Western blot. RESULTS We found that miR-630 was significantly downregulated in PTC tissues and cell lines. Overexpression of miR-630 inhibited PTC cell proliferation and induced cell apoptosis via suppressing the expression of caspase-3 and caspase-6. In addition, up-regulation of miR-630 suppressed the migration and invasion in PTC cells by suppressing EMT progress. Mechanistic investigations showed forced miR-660 expression decreased proteins expression of phosphorylation levels in JAK2/STAT3 signaling. CONCLUSIONS We firstly provided the evidence that miR-630 displayed a tumor-promotive role in PTC progression through modulating JAK2/STAT3 pathway, and that a potential therapeutic strategy through enhancing miR-630 expression might benefit PTC patients.

Abstract
Objective: To investigate secondary factors, laboratory features, treatment options, and prognosis of pure red cell aplastic anemia (PRCA) . Methods: This was a multicenter retrospective clinical study. Patients aged above 18 years newly diagnosed with PRCA between June 1, 2010, and June 1, 2019, were recruited as the main study object. A comparative analysis of remission rate and overall survival rate was made according to different treatment schemes adopted by patients and different drug reduction rates. Results: A total of 67 patients with PRCA were included in this study and the secondary PRCA group accounted for 44.8% (30/67) . The most common secondary factors were thymoma (n=10) and T-cell large lymphocytic leukemia (T-LGLL) (n=6) . The overall response rate of PRCA was 85.7% and the 3-year overall survival rate of PRCA was (74.3±7.5) %. The remission rate of cyclosporine A alone was slightly higher than that of oral glucocorticoid alone or combined with glucocorticoid[90.0% (36/40) vs 75.0% (12/16) , P=0.147]. After patients applied with cyclosporine A treatment reached CR/PR and remained stable for 3-6 months, the dose of cyclosporine A was reduced by 25 mg each time. The cyclosporine A reduction interval of a 25 mg/d reduction in more than 1 month significantly prolonged the median disease-free survival compared with a 25 mg/d reduction in less than 1 month [not reached vs 15 (95% CI 7-23) months, P<0.001]. There were 62.5% (10/16) of patients who responded to the initial or incremental treatment regimen after relapse. Conclusion: PRCA has features of various secondary factors, high overall survival rate, and high remission rate. Treatment with cyclosporine A alone is preferred, and cyclosporine A should be slowly tapered to reduce the risk of later relapse after it takes effect and patients reach a steady state.

Abstract
Objective: To investigate the relationship between urinary polycyclic aromatic hydrocarbons(PAHs) metabolites and pulmonary function in community population. Methods: A total of 4 812 participants were recruited from two communities in Wuhan city from April to May 2011 and two communities in Zhuhai city in May 2012. Information of demographic characteristics and life style was collected by semi-structural questionnaire. Physical examination was performed and pulmonary function was measured. Morning urine was also collected. The concentration of 12 urinary PAHs metabolites was tested and classified into four types by chemical structure, including hydroxynaphthalene, hydroxyfluorene, hydroxyphenanthrene and hydroxypyrene. The level of pulmonary function in different group of urinary PAHs metabolites was compared by using covariance analysis. The association of the urinary PAHs metabolites and pulmonary function was analyzed by using generalized linear model, and the interaction of different population characteristics and life style on the association was analyzed. Results: The age of participants was(51.99±13.64) years old, and 67.66% (n=2 565) of the population were women. The M (P(25), P(75)) of concentration of total urinary PAHs metabolites was 5.72 (3.91,8.72) μg/mmol Cr. After controlling for variables including age, gender, city, Waist-to-Hip Ratio, smoking status, drinking situation, physical activity, cooking meals at home or not, kitchen ventilation and exposure to dust as confounding factors, generalized linear model showed that each 1-unit increase in log-transformed levels of hydroxynaphthalene, hydroxyfluorene, hydroxyphenanthrene, hydroxypyrene and total PAHs was associated with 26.83 (95%CI: -48.18, -5.48) , 21.86 (95%CI: -40.49, -3.23), 26.18(95%CI: -48.27, -4.09), 34.95 (95%CI: -55.95, -13.94), and 35.23 (95%CI: -58.93, -11.54) ml reduction of FVC and 29.36 (95%CI: -47.23, -11.48), 20.79 (95%CI: -36.39, -5.19), 22.65 (95%CI: -41.15, -4.15), 31.44(95%CI: -49.03, -13.85), and 33.20 (95%CI: -53.04, -13.36) ml reduction of FEV(1) respectively (all P values<0.05). Compared to non-alcohol users and participants with home cooking, the association was more evident in alcohol users and participants without home cooking(P for interaction<0.05). Conclusion: The exposure to PAHs was associated with decreased pulmonary function, and the association was more evident in alcohol users and participants without home cooking.

Abstract
OBJECTIVE To investigate the expression of microRNA-324-3p (miR-324-3p) in polycystic ovary syndrome (PCOS) and its effects on the proliferation and apoptosis of ovarian granulosa cells. MATERIALS AND METHODS A total of 60 Sprague-Dawley (SD) rats were randomly divided into normal group (n=30) and experimental group (n=30). Rats in the experimental group were intramuscularly injected with dehydroepiandrosterone (DHEA) (6 mg/100 g of body weight) and 0.2 mL oil for injection, while those in normal group were intramuscularly injected with 0.2 mL oil for injection. The ovarian tissues of PCOS model rats were removed to extract the total ribose nucleic acid (RNA). The expression of miR-324-3p was detected via reverse transcription-polymerase chain reaction (RT-PCR). Primary ovarian granulosa cells were isolated and cultured, and NC-miRNA and miR-324-3p mimic were transfected into cells. After 48 h, cell proliferation and apoptosis were detected via cell counting kit 8 (CCK-8) and flow cytometry assay, respectively. The targeted molecule of miR-324-3p was explored using bioinformatics, and dual-luciferase assay was performed to verify the effect of miR-324-3p on WNT2B expression. Granulosa cells were co-transfected with WNT2B-small-interfering RNA (siRNA) and miR-324-3p mimic, and then cell proliferation and apoptosis were detected via CCK-8 and flow cytometry assay, respectively. RESULTS The expression of miR-324-3p in ovarian tissues of PCOS group was significantly lower than that of normal group (p < 0.01). After transfection with miR-324-3p mimic into granulosa cells, cell proliferation was significantly inhibited and cell apoptosis was promoted (p < 0.01). MiR-324-3p exerted its effect on granulosa cells by directly targeting WNT2B. Silencing WNT2B expression could reverse the effects of miR-324-3p on proliferation and apoptosis of granulosa cells (p < 0.05). CONCLUSIONS The expression of miR-324-3p in the ovary of PCOS rats is decreased significantly. Overexpression of miR-324-3p can reduce the proliferation and induce the apoptosis of granulosa cells via targeting of WNT2B.

Abstract
Objective: To construct and identify a mouse model with conditional knockout (cKO) of p75 neurotrophin receptor (p75NTR-cKO) gene in epidermis cells by Cre-loxP system. Methods: Five p75NTR(flox/flox) transgenic C57BL/6J mice (aged 6-8 weeks, male and female unlimited, the age and sex of mice used for reproduction were the same below) and five keratin 14 promotor-driven (KRT14-) Cre(+ /-) transgenic C57BL/6J mice were bred and hybridized via Cre-loxP system. Five p75NTR(flox/+) ·KRT14-Cre(+ /-) mice selected from the first generation of mice were mated with five p75NTR(flox/flox) mice to obtain the second generation hybrids. After the second generation mice were born 20-25 days, the parts of the mice tail were cut off to identify the genotype by polymerase chain reaction method. Four p75NTR gene complete cKO mice (6 weeks old) and 4 wild-type mice (6 weeks old) were selected and sacrificed respectively. The abdominal skin tissue and brain tissue were excised to observe the expression of p75NTR in the two tissue of two types of mice by immunohistochemical staining. The abdominal skin tissue of two types of mice was obtained to observe the histomorphological changes by hematoxylin and eosin staining. Results: (1) Twenty second generation mice were bred. The genotype of 4 mice was p75NTR(flox/flox)·KRT14-Cre(+ /-)(p75NTR(-/-)), i. e. p75NTR gene complete cKO mice; the genotype of 5 mice was p75NTR(flox/+) ·KRT14-Cre(+ /-), i. e. p75NTR gene partial cKO mice; the genotype of 5 mice was p75NTR(flox/flox)·KRT14-Cre(-/-), and that of 6 mice was p75NTR(flox/+) ·KRT14-Cre(-/-), all of which were wild-type mice. (2) The expression of p75NTR was negative in skin epidermis tissue of p75NTR gene complete cKO mice, while numerous p75NTR positive expression was observed in skin epidermis tissue of wild-type mice. Abundant p75NTR positive expression was observed in brain tissue of both wild-type mice and p75NTR gene complete cKO mice. (3) There was no abnormal growth of skin epidermis tissue in both wild-type mice and p75NTR gene complete cKO mice, with intact hair follicle structure. Conclusions: Applying Cre-loxP system can successfully construct a p75NTR-cKO mice model in epidermis cells without obvious changes in skin histomorphology.
