Abstract
Objective: To investigate the relationship between socioeconomic status (SES) and all-cause mortality in patients with type 2 diabetes. Methods: A total of 17 553 patients with type 2 diabetes were recruited under the National Basic Public Health Service Project in Changshu county, Qingjiangpu district, and Huai'an district in Huai'an city of Jiangsu province as participants. Latent class analysis was applied to classify the individuals based on five socioeconomic indicators. Then, Cox proportional hazards regression models were used to estimate the associations of different levels of SES with all-cause mortality, and stratified analysis was performed according to age and area. Results: Among 100 529.08 person-years of the fo1low-up, the median follow-up time was 5.7 years, and 1 829 deaths occurred during the follow-up period. According to the relevant results of the latent class model, the model of the "three classes" was the best. The related population was then divided into low SES (8 256 people, 47.0%), medium SES (4 427 people, 25.2%), and high SES groups (4 870 people, 27.8%). Compared to patients with high SES, the multivariate-adjusted hazard ratio (95%CI) of all-cause mortality associated with low SES for males and females were 1.84 (1.53-2.21) and 1.41 (1.51-1.72), respectively. Stratified analysis showed that the hazard ration (95%CI) of all-cause mortality associated with low SES for males and females were 1.99 (1.12-2.95) and 2.01 (1.20-3.23), respectively, in people younger than 60 years old, and were 1.90 (1.57-2.31) and 1.40 (1.13-1.73) in people over 60 years old. The HR values (95%CI) for all-cause mortality associated with low SES for the male and females were 1.54 (1.17-2.04) and 1.27 (1.02-1.59) in the urban population with 2.11 (1.55-2.85) and 2.64 (1.17-3.35) in rural population, respectively. Conclusions: Lower SES increased the risk of all-cause mortality in type 2 diabetic patients, which is more significant in younger and rural populations.

Abstract
Objective: To explore the action mechanism of hsa_circ_0000231 in the occurrence and development of tongue squamous cell carcinoma (TSCC). Methods: Tissue samples of 60 TSCC patients were examined. The patients, including 32 males and 28 females, aged from 36 to 84 years old, underwent surgery in the Affiliated Hospital of Nantong University and Affiliated Tumor Hospital of Nantong University from December 2014 to December 2017. Saliva samples were obtained from healthy volunteers (5 males and 5 females, aged from 40 to 75 years old) and 10 TSCC patients. The TSCC cell lines (CAL-27, Tca-8113 and HN-4) were used. The expression levels of hsa_circ_0000231 in 60 pairs of freshly matched TSCC and para-carcinoma tissue samples, 10 pairs of saliva samples and 3 TSCC cell lines were detected by quantitative real-time polymerase chain reaction (qRT-PCR). hsa_circ_0000231 gene interference and lentiviral transfection were constructed, hsa_circ_0000231 in TSCC cell lines CAL-27 and Tca-8113 was knocked down, and the expressions of hsa_circ_0000231 in hsa_circ_0000231 interference group (sh-circ) and no-load lentivirus group (negative control) were tested with qRT-PCR. Cells with the highest knock-down efficiency were selected for CCK-8 test, colony formation assay, transwell invasion assay and scratch assay. The expressions of EMT-related proteins including E-cadherin, snail protein, N-cadherin and vimentin and proteins related to Wnt/β-catenin signaling pathway including β-catenin, C-myc, Bcl-2, MMP-9 and Cyclin D1 were measured by western blot. After TSCC cells in the interference group were co-cultured with Wnt/β-catenin pathway activator LiCl, the expressions of above proteins were re-measured by western blot. TSCC cells in interference group and control group were subcutaneously injected into nude mice to compare the effect of hsa_circ_0000231 knockdown on the growths of the tumors grafted subcutaneously in the nude mice. Statistical analysis software 25.0 was used for data analysis, and t-test or chi-square test was used for comparison between groups. Results: hsa_circ_0000231 was highly expressed in the tissue and saliva samples of TSCC patients and cell lines CAL-27, Tca-8113 and HN-4, but lowly expressed in paired para-carcinoma tissues, saliva samples of healthy people and normal human oral keratinocytes (all P<0.05). Log-rank univariate analysis showed that hsa_circ_0000231 expression level, tumor differentiation degree and T stage were related to the survival of TSCC patients (all P<0.05). Multivariate Cox risk regression model analysis suggested that hsa_circ_0000231 expression level (χ2=5.77,P=0.016) and T stage (χ2=5.27,P=0.029) were independent factors for the poor prognosis of TSCC patients. Western blot showed the expressions of snail protein, N-cadherin and vimentin were down-regulated, but E-cadherin was up-regulated in interference group compared with control group. In interference group, the expressions of β-catenin, C-myc, Bcl-2, MMP-9 and CyclinD1 were down-regulated, which were reversed after TSCC cells were co-cultured with LiCl. The knockdown of hsa_circ_0000231 reduced the proliferation, invasion and metastasis abilities of CAL-27 and Tca-8113 cells, which were reversed after TSCC cells were co-cultured with LiCl. The growth rate and volume of the tumors grafted subcutaneously in interference group using LiCl were greater than those in negative control group. Conclusion: hsa_circ_0000231 is an independent prognostic factor of TSCC. Highly expressed hsa_circ_0000231 can promote the proliferation, invasion and metastasis of TSCC cells.

Abstract
Objective: To estimate the effectiveness of the primary screening strategy for liver cancer in rural areas to provide basic information for the optimization and perfection of the technical program for the early detection and treatment of liver cancer. Methods: Residents including males aged 35-64 and females aged 45-64 from 9 counties in rural China between 2013 and 2015 were selected as the target population. The participant was classified into a high-risk and non-high-risk group based on the standardized questionnaire or HBsAg, and the Chi-squared test was applied to compare differences between the two groups. The Cox proportional hazard regression models were applied to assess hazard ratio (HR) and its 95% confidence interval (CI). Results: 358 348 participants were recruited from 2013 to 2015. 1 196 individuals were identified with liver cancer until December 31, 2021, with an incidence density of 52.0/10(5) person-years. Of the participants, 54 650 were assessed as high risk (15.3%) based on the questionnaire and the status of HBsAg. The high-risk population had a higher incidence density (168.3/10(5) person-years vs 31.5/10(5) person-years) and higher risk of developing liver cancer (HR=2.98, 95% CI=2.64-3.35), compared to the non-high-risk group. Based on the questionnaire-based high-risk assessment system, 47 884 (13.4%) individuals were identified as high risk, who showed statistical differences in terms of incidence density and incidence risk, in comparison to the low-risk population (all P<0.05). HBsAg can screen out a higher proportion of high-risk individuals who are women, non-smokers, non-drinkers, and individuals without a family history of liver cancer (all P<0.05). The sensitivity analysis of the effectiveness of the whole primary screening method is stable, and high-risk individuals still had a higher risk of liver cancer. Conclusions: The primary screening method of the questionnaire-based risk assessment system and HBsAg can achieve satisfactory effectiveness. The questionnaire-based risk assessment system could identify high-risk individuals to some extent, however, it still needs to be improved to meet the actual requirements.

Abstract
Objective: To study the clinical and microbiological characteristics of hypervirulent Klebsiella pneumoniae (hvKP) lung abscess, and to compare with the classic Klebsiella pneumoniae (cKP) lung abscess. Methods: A total of 18 patients with Klebsiella pneumoniae lung abscesses admitted to the First Affiliated Hospital of Zhejiang University School of Medicine from January 2017 to September 2020 enrolled. The strains with positive result of string test were defined as hvKP, and the negative strains were defined as cKP. The patients' basic diseases, symptoms, laboratory data and other clinical characteristics were collected. The microbiological characteristics of the strains included as following: VITEK method to determine the in vitro susceptibility of the strains to antibiotics; PCR to detect the capsular serotypes and virulence genes. The differences in clinical characteristics and microbiological characteristics of strains between hvKP group and cKP group were compared. Results: Among the 18 patients with Klebsiella pneumoniae lung abscess, 12 were hvKP infection, mainly male (10 cases), with a median age of 59.0 years; 8 cases in the hvKP group had an onset time of ≤2 weeks, and the median onset time was 10.5 days. There were significantly more diabetes (12 cases) and extrapulmonary abscesses (11 cases) in hvKP group than those in cKP group (both P<0.001). The extrapulmonary abscesses in the hvKP group were mainly liver abscesses (10 cases), and 4 cases were multi-site (≥3) abscesses. The number of indwelling catheters and invasive procedures before infection were higher in cKP group than those in hvKP group (both P=0.025). The imaging of Klebsiella pneumoniae lung abscess was mainly subpleural with the size of less than 10 cm. There were more multiple abscesses cases in hvKP group (9 cases) than cKP group (P=0.009). The median interval time between the detection of a pulmonary abscess and an extrapulmonary abscess was 1.0 day. The resistance rate of common antibiotics was significantly lower in hvKP than cKP. Conclusions: hvKP lung abscesses are more common in patients with diabetes, and the clinical manifestations are nonspecific. The lung imaging manifestations are multiple subpleural abscesses, indicating hematogenous dissemination. Liver abscesses were present in most cases, suggesting the source of infection. The main virulent gene of hypervirulent Klebsiella pneumoniae is aero. For patients with hvKP lung abscess, attention should be paid to finding hidden lesions.

Abstract
Objective: To describe gastric cancer incidence in Suzhou cohort, explore the environmental risk factors of gastric cancer in Suzhou, and provide appropriate suggestions for gastric cancer prevention and control. Methods: The participants were from the Suzhou cohort of China Kadoorie Biobank. Baseline survey was conducted from 2004 to 2008, followed by long-term follow-up until December 31, 2013. After the exclusion of those who had been previously diagnosed with peptic ulcer and malignant tumor reported at baseline survey and gastric cancer within six months after enrollment, a total of 50,136 participants were included. Cox proportional risk models were used to identify risk factors of gastric cancer and their hazard ratios in Suzhou. The effect modifications of gender on the association between risk factors and gastric cancer were analyzed. Results: In the follow-up of 7.19 years (median), 374 gastric cancers cases occurred. The standardized incidence was 94.57 per 100 000 person-years. Multivariate Cox proportional risk model analysis found that age (10 years old as a age group, HR=2.20, 95%CI: 1.92-2.53, P<0.001), current smoking (HR=1.84, 95%CI: 1.10-3.07 P=0.020), consumption of preserved vegetables weekly (HR=2.28, 95%CI: 1.28-4.07, P=0.005) and daily (HR=2.05, 95%CI: 1.16-3.61, P=0.013) were risk factors for gastric cancer. Female (HR=0.44, 95%CI: 0.25-0.76, P=0.003) and refrigerator use (10 years as a limit, HR=0.85, 95%CI: 0.74-0.97, P=0.016) were protective factors for gastric cancer. Further analysis showed that there was heterogeneity between males and females in the association between refrigerator use years and the incidence of gastric cancer (P=0.009), and there was an interaction effect between gender and refrigerator use on the incidence of gastric cancer (P=0.010). Conclusions: The incidence of gastric cancer in Suzhou cohort was high. The risk factors of gastric cancer varied. There was a synergistic interaction effect between gender and refrigerator use years on the incidence of gastric cancer.

Abstract
Objective: To investigate the detection types and aggregation of high-risk population of cardiovascular disease (CVD) in Jiangsu province and the related influencing factors to provide reference for the prevention and control of cardiovascular disease. Methods: A total of 120 211 participants were included in the investigation. Information was collected by questionnaire based survey, physical examination and biochemical tests. χ2 test and multivariate logistic regression were used for statistical analysis. Results: The detection rate of CVD high risk was 25.03%. The detection rates were 19.01%, 4.85%, 3.18% and 5.31% for hypertension, dyslipidemia, cardiovascular history and WHO assessed risk ≥20% types, respectively. Male, rural, old age, low education level, low family income, drinking, waist circumference exceeding standard, overweight and obesity were risk factors of CVD (all P<0.01). The composition ratios of aggregation of 1, 2 and ≥3 high risk types of CVD were 74.01%, 22.91% and 3.08%, respectively. With the increase of aggregation types, the correlation strength increased with age, rural residents, education level and annual family income. Conclusion: Targeted measures should be carried out according to different influencing factors for the prevention and control of CVD in Jiangsu province in order to achieve the maximum prevention and control effect with the minimum cost.

Abstract
Objective: To explore the mediating effect of physical activity on association between sedentary leisure-time and obesity indexes among hypertensive individuals. Methods: After excluding of those with a prior history of heart disease, stroke and cancer, a total of 20 178 hypertensive participants in the China Kadooire Biobank (CKB) study from Wuzhong district of Suzhou city were included. Mediating effect analysis was used to analyze the mediating effect of physical activity (PA) on correlation between sedentary leisure-time and body fat percentage (BFP), waist circumference (WC) and body mass index (BMI). Results: After adjusted for age, gender, smoking status, alcohol consumption, education levels, intake frequencies of meat and intake frequencies of fresh fruit, sedentary leisure-time (SLT) was negatively correlated with PA (β=-0.246, P<0.001), but positively associated with BFP (β=0.061, P<0.001), WC (β=0.087, P<0.001) and BMI (β=0.071, P<0.001). After including the mediator variable PA, the direct effect of SLT on obesity index was still significant. PA was negatively correlated with BFP, WC and BMI (β=-0.052, -0.083 and -0.028, respectively, P<0.001). Analysis of mediating effect indicated that the association of SLT with BFP, WC and BMI were partly mediated by PA, the proportion of mediating effect was 20.820%, 23.421% and 9.915%. Stratified by gender, PA had mediating effect on SLT and all obesity indexes in women, while only on SLT and BFP and WC in men. Conclusions: There is a significant mediating effect of PA on correlation between SLT and obesity indexes among hypertensive individuals. Hypertensive patients should increase the level of physical activity and reduce sedentary behavior to achieve a profounder healthy effect.

Abstract
Objective: To investigate the association between occupational hazard exposures and small airway function among middle-aged and elderly people. Methods: From July to December in 2015, a multistage cluster random sampling method was used to select 3 600 residents aged 40 years old and above from 6 chronic obstructive pulmonary disease surveillance points in Jiangsu province. A cross-sectional survey was conducted to collect relevant information. Multivariable linear regression model was performed to determine the relationship between occupational hazard exposures and small airway function. Results: A total of 3 347 participants were included in the final analysis, and 44.6% of participants had been exposed to occupational hazard exposures. Compared with participants without the exposure history of occupational hazards, the significantly lower post-bronchodilator FEF50%, FEF75% and MMEF levels were observed in those with the exposure history of occupational hazards (β=-82.74, -55.43 and -91.57, respectively). Post-bronchodilator FEF75% and MMEF (β=-51.78 and -79.47, respectively) in the participants with the exposure history of occupational dust and post-bronchodilator FEF50%, FEF75% and MMEF (β=-96.84, -32.87 and -75.72, respectively) in the participants with the exposure history of occupational harmful gas all showed a lower level. Post-bronchodilator FEF75% was negatively associated with occupational hazard exposures in males (βmale=-91.65 vs. βfemale=-27.21, P for interaction=0.022). Conclusions: The small airway function is worse in the middle-aged and elderly population with the exposure history of occupational hazards, and it is more significant in the male population.

Abstract
Objective: To analyze the clinical effect of extracorporeal membrane oxygenation (ECMO) in the treatment of burn patients with acute respiratory distress syndrome (ARDS). Methods: The retrospective observational study and the systematic review were applied. From March 2014 to July 2020, five burn patients with ARDS received ECMO treatment in the First Affiliated Hospital of Army Medical University (the Third Military Medical University). All the five patients were male, aged from 40 to 62 years. The average total burn surface area was 58.8% total body surface area (TBSA) and four cases had severe inhalation injury. Patient's ECMO starting time, duration and mode, and whether successfully weaned or the cause of death, and others. were recorded. Furthermore, the changes of oxygenation and infection before, during, and after utilizing ECMO were analyzed. PubMed and Web of Science from the establishment of each database to August 2021 were searched using "Extracorporeal Membrane Oxygenation", "ECMO", "burn", "inhalation" as the search terms and "Title/Abstract" as the field to retrieve the clinical articles that meet the selection criteria . Basic information were extracted from the articles, including sample size, gender, age, total burn area, inhalation injury, the indication of ECMO, the start and lasting time of ECMO, ECMO mode, rate of successful weaning, complications of ECMO, mortality, the combined application of continuous renal replacement therapy (CRRT). Results: Five patients started venovenous ECMO on an average of 10.2 days after injury and lasted an average of 180.4 hours. Three out of 5 patients were weaned successfully with one patient survived. Four patients died of multiple organ dysfunction syndrome (MODS) and septic shock. Compared with those before ECMO treatment, the arterial oxygen partial pressure (PaO2) and oxygen saturation in arterial blood (SaO2) of three successfully weaned patients obviously increased during and after ECMO treatment. The fraction of inspired oxygen (FiO2) decreased below 50% and PaO2/FiO2 ratio increased above 200 mmHg (1 mmHg=0.133 kPa) during and after ECMO. Furthermore, lactic acid and respiratory rate decreased, basically. Compared with those before ECMO, PaO2 and SaO2 in the other two patients during ECMO, who failed to be weaned, continuously decreased while lactic acid increased. Before and during ECMO, the PaO2/FiO2 ratios of unsuccessfullg weaned cases were less than 200 mmHg, and partial pressure of carbon dioxide in arterial blood (PaCO2) were more than 40 mmHg. Compared with those before ECMO, there were no significant changes in body temperature during and after ECMO, which were less than 38 ℃. Compared with those before ECMO, the leucocyte number (the index without this in unsuccessfully weaned cases was omitted, the same as below) in four patients showed a significant decrease during ECMO, but rose after removal of ECMO. The proportion of neutrophils in three patients were slightly higher during ECMO than before ECMO, and did not change significantly after removal of ECMO. Compared with those before ECMO, platelet counts in three patients were significantly reduced during ECMO, and all five patients during ECMO were below normal levels. Compared with those before ECMO, the procalcitonin levels in four deaths were significantly increased during ECMO. Catheter culture of microorganism was performed in three successfully weaned patients, all of which were negative. A total of 13 literature were included, ranging from 1990 to 2019. The sample size in 6 studies was less than 10, and the sample size in 4 studies was between 10 and 20, and only 2 literatures had a sample size larger than 50. ECMO was applied in 295 burn patients with overall mortality of 48.8% (144/295), including 157 adults and 138 children. The most common indication of ECMO was severe ARDS. Among 157 adult burn patients (95 males and 65 females), 36 cases had inhalation injury. The average burn area was 27%-37%TBSA in 5 reported studies and was more than 50%TBSA in 2 reported studies. The most common mode was venovenous ECMO. ECMO treatment began 26.5 hours to 7.4 days after injury and lasted from 90 hours to 18 days, and the rate of successful weaning ranged from 50% to 100%. The most common complications were bleeding and infection. The mortality was 52.9% (83/157). MODS and sepsis were the leading causes of death. Among 138 pediatric burn patients (77 boys and 61 girls), 29 patients had inhalation injury. The average burn area was 17%-50.2%TBSA in 3 studies. ECMO treatment lasted from 165.2 hours to 324.4 hours. Bleeding was the most common complication. The mortality was 44.2% (61/138). Conclusions: ECMO is an effective strategy for the salvage treatment of burns complicated with ARDS. Furthermore, the prevention and treatment of bleeding, infection and organ dysfunction should be emphasized during the use of ECMO. More importantly, evidence-based guidelines for burns are urgently needed to further improve the clinical effect of ECMO.

Abstract
Abstract
Introduction
The residual SYNTAX score (rSS) as the SYNTAX remaining after completion of percutaneous coronary intervention (PCI) was proved to be related to poor outcomes.
Purpose
This study aimed to investigate the association of culprit-plaque morphology with rSS and the predictive value of rSS for major adverse cardiac events (MACE) in patients with ST-segment elevation myocardial infarction (STEMI).
Methods
A total of 274 STEMI patients undergoing preintervention optical coherence tomography examination were included and divided into 3 groups – rSS=0 (n=72), 0<rss≤8>8 (n=68). Baseline clinical data and culprit-plaque characteristics were compared. MACE was defined as the composite of all-cause death, recurrence of myocardial infarction (MI), stroke and unplanned revascularization of any coronary artery.
Results
There was a significant difference in the prevalence of plaque ruptures, lipid-rich plaques, and calcification among the three groups (plaque rupture: 44.4% versus 59.0% versus 64.7%, lowest to highest rSS, p=0.04; lipid-rich plaque: 40.3% versus 54.5% versus 69.1%, lowest to highest rSS, p=0.003; calcification: 38.9% versus 52.5% versus 61.8%, lowest to highest rSS, p=0.024). Multivariate logistic regression analysis indicated that rSS>8 was an independent predictor for plaque rupture (OR: 2.21, 95% CI: 1.19–4.19, P=0.013). During a mean follow-up of 2.2 years, MACE occurred in 47 (17.2%) patients. In fully adjusted analyses, rSS was independently associated with MACE (HR: 1.06, 95% CI: 1.02–1.10, P=0.005); patients with rSS >8 had higher MACE risk compared to rSS=0 (HR: 2.68, 95% CI: 1.11–6.5, P=0.029).
Conclusion
In STEMI patients, culprit-plaque morphology was significantly correlated with rSS, and elevated rSS was independently associated with cardiovascular risk.</rss≤8>

Abstract
Objectives: To compare the impact of ticagrelor or clopidogrel on serum uric acid levels among patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and further evaluate the effects of variation of serum uric acid levels on platelet reactivity. Methods: STEMI patients who admitted to Fuwai Hospital from April 2017 to January 2020, and underwent primary PCI and discharged alive with aspirin and ticagrelor or clopidogrel were included in this study. Patients were divided into ticagrelor group and clopidogrel group. The baseline clinical data were collected. Serum uric acid and creatinine levels at baseline and 30 days post-PCI were measured. Light transmittance aggregometry was used to assess maximum aggregation rate induced by adenosine diphosphate and arachidonic acid. The changes of serum uric acid and creatinine were compared between the two groups. Multivariate logistic regression was performed to evaluate independent related factors for rise in the uric acid levels, and the effect of variation of serum uric acid level on platelet reactivity was analyzed. Results: A total of 967 patients were included, the age was (59.4±12.1) years, and 163 case were female. There were 550 cases in ticagrelor group (56.9%) and 417 cases in clopidogrel group (43.1%). Baseline serum uric acid and creatinine levels were similar between the 2 groups. At 30 days, the serum uric acid level [(347.2±96.5) mmol/L vs. (341.2±105.3) mmol/L, P=0.009] and absolute [46.4 (-2.4, 88.1) mmol/L vs. 25.0 (-21.9, 73.0) mmol/L, P=0.001] and percentage [13.2 (-0.01, 29.0) % vs. 7.9 (-5.7, 25.0) %, P=0.007] increase in the serum uric acid levels were significantly higher in ticagrelor group than in clopidogrel group. The level of serum creatinine at 30 days was significantly lower in ticagrelor group than in clopidogrel group [(89.7±21.3) μmol/L vs. (94.4±43.9) μmol/L, P<0.05], whereas there were no differences in absolute [8.0 (-1.4, 16.6) μmol/L vs. 7.8 (-2.0, 16.6) μmol/L] and percentage [10.5 (-1.7%, 22.6%) vs. 9.8 (-2.4%, 22.1%)] change in the serum creatinine between the 2 groups (all P>0.05). Logistic regression analysis showed that, after adjusting for confounding factors, ticagrelor therapy was an independent related factor of serum uric acid elevation (OR=1.582, 95% CI:1.023-2.447, P=0.039). The variation of the serum uric acid levels did not affect platelet aggregation and the percentage of high platelet reactivity in both groups. Conclusions: Ticagrelor use is related to a significant increase in the serum uric acid levels at 30 days post-PCI in this patient cohort. The variations in the uric acid levels do not increase the percentage of high platelet reactivity in STEMI patients treated with ticagrelor or clopidogrel.

Abstract
Objective: To investigate the relationship between pattern recognition receptor triggering receptors expressed on myeloid cells-1 (TREM-1) and M1/M2 polarization in macrophages stimulated by Porphyromonas gingivalis lipopolysaccharide (Pg-LPS), so as to explore the mechanism of TREM-1 in periodontitis. Methods: Human monocytic cell line THP-1 were induced to differentiate into macrophages by phorbol-12-myristate-13-acetate and stimulated by 0 (blank control group) and 1 μg/ml Pg-LPS (LPS group), respectively. LP17, the TREM-1 inhibitor (LPS+LP17 group) and its control peptide (LPS+control peptide group) with final concentration of 0.1 μg/ml were added at the same time. After 24 hours stimulation, the expression of TREM-1, M1 markers and related cytokines [CD86, tumor necrosis factor-α (TNF-α), interleukin (IL)-1β], M2 markers and related cytokines (CD206,IL-10) mRNA were detected by real-time quantitative-PCR (RT-qPCR), the level of TREM-1, CD86 and CD206 proteins were detected by Western blotting, and TNF-α, IL-1β and IL-10 in the macrophage culture supernatant were detected by enzyme linked immunosorbent assay. Results: After 24 h of cell culture, the relative expressions of TREM-1 mRNA (1.40±0.14) and protein (3.85±0.24) in macrophages in the LPS group increased compared with the blank control group (1.01±0.18 and 1.00±0.05, respectively) (P<0.05). Meanwhile, the expression levels of M1 markers CD86 mRNA and protein [LPS group vs blank control group were (1.42±0.01 vs 1.00±0.09) and (1.55±0.07 vs 1.00±0.10), respectively] were up-regulated (P<0.01), and the expressions of mRNA and protein of M1 related cytokines TNF-α and IL-1 increased (P<0.05). After the addition of TREM-1 blocker LP17, the levels of mRNA and protein of TREM-1 showed no significant changes (P>0.05), while the levels of CD86 mRNA (0.96±0.00) and protein (1.36±0.02) decreased (P<0.05), and the levels of TNF-α and IL-1 further decreased (P<0.05). For M2 marker CD206 and related cytokine IL-10, CD206 mRNA (0.56±0.05) and protein (0.25±0.04) were significantly down-regulated (P<0.01) compared with the blank control group (1.02±0.25 and 1.00±0.10, respectively), and IL-10 mRNA was up-regulated compared with the blank control group (P<0.05), with no significant change in protein (P>0.05). After the addition of LP17, the expressions of CD206 and IL-10 mRNA in the LPS+LP17 group were further down-regulated compared with the LPS group (P<0.05), and there was no statistically significant difference between the two groups in protein level (P>0.05). Conclusions: TREM-1 and its downstream signaling pathway might be involved in M1 polarization of Pg-LPS-mediated macrophages, thus playing a pro-inflammatory role in the development of periodontitis. There is no obvious evidence that TREM-1 is involved in regulating M2 polarization of Pg-LPS-mediated macrophages.

Abstract
Objective: To investigate the current status of the diagnosis and treatment of pulmonary cryptococcosis in respiratory medicine and improve the understanding of the clinical characteristics of HIV-negative pulmonary cryptococcosis in China. Methods: A prospective multi-center open cohort study was designed to screen for pulmonary cryptococcosis in the general wards and intensive care units of the Department of Respiratory Diseases in 22 hospitals. The HIV-negative patients with positive cryptococcal etiological diagnosis based on smear culture, antigen detection and histopathology were enrolled in the study. The clinical data of enrolled patients were collected and analyzed. Results: A total of 457 cases of pulmonary cryptococcosis were enrolled, among which 3.28% (15/457) were disseminated infections. The case fatality rate was 0.88% (4/457). The majority of the cases were diagnosed by histopathological examinations (74.40%, 340/457) and cryptococcus antigen detection (37.64%, 172/457). Patients with pulmonary cryptococcosis accounted for 2.04‰ (457/223 748) of the total hospitalized patients in the Department of Respiratory Diseases during the same period, and the ratio was the highest in south and east China. Meanwhile, 70.24% (321/457) of the patients had no underlying diseases, while 87.75% (401/457) were found to have immunocompetent status. Cough and expectoration were the most common clinical symptoms in patients with pulmonary cryptococcosis. However, 25.16% (115/457) of the patients had no clinical symptom or physical signs. In terms of imaging features on pulmonary CT, multiple pulmonary lesions were more common than isolated lesions, and there were more subpleural lesions than perihilar or medial lesions. Morphologically, most of the lesions were middle-sized nodules (1-5 cm) or small-sized nodules (3 mm to 1 cm). The sensitivity of serum cryptococcus antigen test was 71.99% (203/282). Moreover, antigen-positive patients differed from antigen-negative patients in terms of basic immune status, clinical symptoms, imaging features and infection types. Meanwhile, immunocompromised patients differed from immunocompetent patients in terms of clinical symptoms, physical signs, infection-related inflammation indicator levels, imaging features, serum cryptococcus antigen positive rate and prognosis. Conclusions: The majority of cases of HIV-negative pulmonary cryptococcosis in China had no underlying disease or immunocompromised status, and the overrall prognosis was favorable. However, early diagnosis of HIV-negative pulmonary cryptococcosis remains challenging due to the complicated manifestations of the disease.

Abstract
Long-term intake of large amounts of ethanol leads to enterogenous endotoxemia. Reactive oxygen species, high concentrations of adenosine triphosphate and uric acid activate the pyroptosis system, which then cleaves the pore formation mechanism of gasdermin-D, leading to the death of liver cells, accompanied by the release of interleukin-1β, interleukin-18, and other inflammatory factors. This series of processes activates the immune system, mediates a cascade of inflammation, and promotes the development of alcoholic liver disease from steatosis to inflammation and fibrosis.

Abstract
Objective: To estimate the incidence/mortality of ovarian cancer in 2015 and the incidence/mortality trend of ovarian cancer from 2006 to 2015 in Jiangsu province, and provide evidence for prevention and treatment of ovarian cancer in Jiangsu. Methods: The incidence and death data of cancer in Jiangsu from 2006 to 2015 collected from 35 cancer registries and verified by Jiangsu provincial CDC in 2018 were used for the extraction of ovarian cancer data. The data were stratified by urban and rural, gender and age groups. The crude rates of incidence and mortality, age-standardized incidence/mortality rates (ASIR/ASMR), cumulative incidence/mortality rates (0-74 years) and truncated incidence/mortality rates (35-64 years) of ovarian cancer were calculated. Chinese population census in 2000 and world Segi's standard population were used for the calculations of age-standardized incidence/mortality rates. Software Joinpoint 4.7.0.0 was used to analyze the annual percentage changes (APCs) of two rates from 2006 to 2015. Results: It was estimated that 2 229 ovarian cancer cases occurred in Jiangsu in 2015, accounting for 2.23% of all cancer cases and ranking 12(th) of cancer incidence in women. The crude incidence rate was 5.91/100 000, the age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 4.01/100 000 and 3.81/100 000, respectively. The cumulative incidence rate (0-74 years) was 0.42%. It was estimated that 1 239 deaths of ovarian cancer occurred in Jiangsu in 2015, accounting for 2.18% of all cancer deaths and ranking 13(th) of cancer mortality in women. The crude mortality rate was 3.29/100 000, the ASMRC and ASMRW were 1.99/100 000 and 1.96/100 000, respectively. The cumulative mortality rate (0-74 years) was 0.24%. The APCs of crude incidence rate and crude mortality rate were 4.66% (95%CI: 2.11%-7.29%) and 7.45% (95%CI: 5.46%-9.47%) (all P<0.05). The APCs of ASIRC and ASIRW were 2.30% (95%CI: -0.32%-4.99%) and 2.41% (95%CI: -0.29%-5.20%) (all P>0.05), and the APCs of ASMRC and ASMRW were 4.43% (95%CI: 2.54%-6.36%) and 4.55% (95%CI: 2.58%-6.57%) (all P<0.05). Conclusions: The incidence and mortality of ovarian cancer in Jiangsu were at low levels, and were higher in urban areas than in rural areas. The crude incidence and mortality rates increased, and age-standardized incidence rate was stable, but age-standardized mortality rate increased obviously.

Abstract
Objective: To observe the changes of LHX4 and DIS3L mRNA and protein expression in Nthy-ori-3-1 cells after the treatment of thyroid disruptor p, p'-DDE. Methods: Nthy-ori-3-1 cells in logarithmic growth phase were treated with 0, 0.5, 1.0, 2.0 and 5.0 μg/ml p, p'-DDE solution. The growth state and morphology of the cells were observed by microscope. The mRNA levels of LHX4 and DIS3L were detected by real-time fluorescent quantitative PCR, and the protein expression levels of LHX4 and DIS3L were detected by Western blot. Results: when the concentrations of p, p'-DDE were 0, 0.5, 1.0 and 2.0 μg/ml, Nthy-ori-3-1 cells grew normally. There were 33 differential genes in 2.0 μg/ml group, among which 13 genes were down regulated and 20 genes were up-regulated. Compared with the control group, the protein expression levels of LHX4 and DIS3L in 1.0 and 2.0 μg/ml groups were significantly decreased (P<0.05) , and the relative expression levels of LHX4 and DIS3L protein mRNA in 1.0 μg/ml group were significantly decreased (P<0.05) . Conclusion: p, p'-DDE can affect the protein expression of LHX4 and dis3l in nthy-ori-3-1 cells.

Abstract
Objective: To understand the incidence of esophageal cancer in population at high risk in Yangzhong of Jiangsu province. Methods: Cluster random sampling method was conducted to select several natural villages from the high risk area of esophageal cancer in Yangzhong during 2011-2017. Local residents aged 40-69 years were selected as the target population and a total of 14 687 persons were diagnosed esophageal cancer by endoscopy and pathology. Results: Precancerous lesions were detected in 341 persons, with the detection rate as 2.32% (341/14 687). Among them, there were 234 (1.59%) cases with mild and 107 (0.73%) cases with moderate esophageal hyperplasia. There were 77 positive cases with esophageal hyperplasia and the detection rate was 0.52%. Among these positive cases, 41 showed severe esophageal hyperplasia/carcinoma in situ (0.28%), with another 19 as early esophageal cancer (0.13%) and 17 with invasive carcinoma (0.12%). The overall early detection rate of positivity through active screening was 77.92% (60/77), with trends of upwarding and then downwarding. The detection rate of esophageal lesions in men was higher than that in women (P<0.05), but without significant gender specific differences seen in the detection rates of early esophageal cancer or invasive carcinoma (P>0.05). The detection rates of all lesions other than invasive carcinoma, gradually increased with age (P<0.05). The detection rate of invasive carcinoma reached the highest (0.39%, 10/2 547) in the age group of 60-years and slightly decreased in the age group of 65-years old. Conclusions: Considerable numbers of patients with cancer and precancerous lesions in groups at high-risk can be found through the screening program for esophageal cancer, suggesting that the screening program is of great significance in improving the survival rate and quality of life. Attention should be paid to men, with elderly groups in particular, at high-risk in order to increase the detection rate of early cases.

Abstract
Objective: To explore the associations between perceived built environment attributes and adults' leisure-time physical activity in four cities of China. Methods: Multistage cluster random sampling method was used to select adults aged 25 to 64 in Hangzhou, Suzhou, Chengdu, and Qingdao. Data were collected from June 2017 to July 2018. The perception of the urban built environment was assessed by the neighborhood environment walkability scale-abbreviated (NEWS-A), and the physical activity was assessed by the International Physical Activity Questionnaire. Generalized linear mixed models were used to explore the relationship between the perceived built environment and leisure-time physical activities. Results: A total of 3 789 participants were included in the analysis. After adjusting for potential confounders, better access to public services (OR=1.34, 95%CI: 1.02-1.75) and higher aesthetic quality (OR=1.37, 95%CI: 1.09-1.73) were positively associated with the possibility of engaging in leisure-time physical activity in the past week. Similarly, these two attributes were positively associated with leisure-time walking. Higher scores on the perception of street connectivity were positively associated with leisure-time walking [exp(β)=1.09, 95%CI: 1.00-1.19]. Higher residential density [exp(β)=1.000 4, 95%CI:1.000 0-1.000 8], better access to physical activity destinations[exp(β)=1.09, 95%CI: 1.00-1.19], and better aesthetics [exp(β)=1.11, 95%CI:1.00-1.22] were associated with higher leisure-time physical activity. Similarly, these three attributes were positively associated with the possibility of meeting the WHO recommendations. Conclusion: Changing some urban built environment attributes may increase leisure-time physical activity.

Abstract
Objective: To evaluate the association betweew family history of diabetes and incident diabetes of adults. Methods: A total of 49 266 participants in the China Kadoorie Biobank (CKB) study from Wuzhong district of Suzhou city were included in the analysis, after the exclusion of those with heart disease, stroke, cancer and diabetes at baseline survey. The person-year of follow-up was calculated from the date on completion of baseline survey to the date on any firstly-occurred event, i.e., diabetes incidence, death, loss of follow-up, or December 31, 2013. Cox regression model was used to estimate the hazards ratios of the association between family history of diabetes and incident diabetes. Results: During 348 677 person-years of the follow-up (median 7.08 years), a total of 423 men and 791 women were diagnosed as having diabetes. Compared to those without diabetic family history, participants with family history of diabetes showed a higher risk of diabetes, with a HR (95%CI) of 1.90 (1.57-2.29), and the risk increased with the number of relatives suffering from diabetes (Pfor trend<0.05). The family history of maternal type, sibling type, and sibling and parental type had a statistically significant association with the risk of diabetes. The adjusted HR (95%CI) was 2.03 (1.45-2.77), 2.07 (1.56-2.68) and 2.39 (1.14-4.34), respectively. Modification effects of tobacco smoking, alcohol drinking, body mass index and physical activity on the association between diabetic family history and risk of diabetes were not observed in the study (Pfor interaction >0.05). Conclusions: Diabetic family history is associated with the increased incident diabetes, and the risk increased with the number of relatives suffering from diabetes.

Abstract
Objective: To determine whether 60 Gy is superior to standard 50 Gy for definitive concurrent chemoradiation(CCRT) in esophageal squamous cell carcinoma (ESCC) using modern radiation technology in a phase Ⅲ prospective randomized trial. Methods: From April 2013 to May 2017, 331 patients from 22 hospitals who were pathologically confirmed with stage ⅢA-ⅣA ESCC were randomized to 60 Gy or 50 Gy with random number table. Total of 305 patients were analyzed, including 152 in 60 Gy group and 153 in 50 Gy group. The median age was 63 years, 242(79.3%) males and 63(20.7%) females. The median length of primary tumor was 5.6 cm. The clinical characteristics between two groups were comparable. All patients were delivered 2 Gy per fraction, 5 fractions per week. Concurrent weekly chemotherapy with docetaxel (25 mg/m(2)) and cisplatin (25 mg/m(2)) and 2 cycles consolidation chemotherapy with docetaxel (70 mg/m(2)) and cisplatin (25 mg/m(2), d1-3) were administrated. The primary endpoint was local/regional progression-free survival (LRPFS). The data were compared with Pearson chi-square test or Fisher's exact test. Results: At a median follow-up of 27.3 months, the disease progression rate was 37.5% (57/152), 43.8% (67/153) in the high and standard-dose group, respectively (χ(2)=1.251, P=0.263). The 1, 2, 3-year LRPFS rate was 75.4%, 56.8%, 52.1% and 74.2%, 58.4%, 50.1%, respectively (HR: 0.95, 95%CI: 0.69-1.31, P=0.761). The 1, 2, 3-year overall survival rate was 84.1%, 64.8%, 54.1% and 85.4%, 62.9%, 54.0%, respectively (HR: 0.98, 95%CI: 0.71-1.38, P=0.927). The 1, 2, 3-year progression-free survival rate was 70.8%, 54.2%, 48.5% and 65.5%, 51.9%, 45.1%, respectively (HR: 0.93, 95%CI: 0.68-1.26, P=0.621). The incidence rates in toxicities between the two groups were similar except for higher rate of severe pneumonitis in high dose group (χ(2)=11.596, P=0.021). Conclusions: The efficacy in disease control is similar between 60 Gy and 50 Gy using modern radiation technology concurrent with chemotherapy for ESCC. The 50 Gy should be recommended as the regular radiation dose with CCRT for ESCC.

Abstract
Objective: To investigate the association between postprocedural D-dimer, high sensitivity C-reactive protein(hs-CRP) and low-density lipoprotein-cholesterol(LDL-C) and outcomes of acute myocardial infarction (AMI) patients treated by percutaneous coronary intervention(PCI), in order to clarify the impacts of thrombotic, inflammatory and cholesterol risks on long-term prognosis. Methods: Patients with AMI who underwent emergency PCI from January 2010 to June 2017 in Fuwai Hospital with complete baseline data were enrolled. Patients were stratified into four groups according to quartiles of D-dimer, hs-CRP and LCL-C. Cox regression was used to analyze the relationship between these biomarkers and prognosis. Restricted cubic spline (RCS) was used to characterize the continuous association between risk of all-cause death and biomarkers. The primary outcome was all-cause death. Results: A total of 3 614 patients were included in the analysis. The age was (59.2±12.0) years old, and 2 845 (78.7%) were male and 3 161 (87.5%) patients were diagnosed as ST-segment elevation myocardial infarction. The follow-up time was 652 (414, 1 880) days. Survival analysis showed that postprocedural D-dimer and hs-CRP were significantly associated with all-cause mortality (all P<0.05). Cox regression with multiple adjustments showed that patients with D-dimer≥580 μg/L presented higher risk of all-cause death (HR=2.03, 95%CI 1.22-3.38, P=0.006), compared to patients with D-dimer<220 μg/L. RCS analysis showed that risk of all-cause death was stably high when D-dimer reached 500 μg/L. Multivariable Cox regression also showed that patients with hs-CRP<2.74 mg/L (HR=1.86, 95%CI 1.10-3.15, P=0.020)or hs-CRP≥11.99 mg/L (HR=2.14, 95%CI 1.35-3.40, P=0.001) presented higher mortality compared to patients whose hs-CRP was 2.74-7.18 mg/L. RCS analysis indicated a J-shaped relation between hs-CRP and mortality, as greater risk of death was observed when hs-CRP was lower than 2 mg/L or higher than 10 mg/L. LDL-C was not associated with outcomes (all P>0.05). Conclusions: Postprocedural D-dimer is significantly associated with long-term prognosis of AMI patients treated by PCI. Patients with extremely high or low levels of hs-CRP presents worse outcomes. Intensive and tailored antithrombotic or anti-inflammatory therapies should be considered for patients with increased thrombotic risk and those with extremely high or low inflammatory risk.

Abstract
Objective: To explore the transcriptional regulation mechanism of transforming growth factor β(1) (TGF-β(1)) on Meox1 and its effect on cell migration of adult human dermal fibroblasts (HDF-a). Methods: (1) HDF-a cells were cultured in RPMI 1640 complete medium (hereinafter referred to as routinely cultured). The cells were divided into TGF-β(1) stimulation group and blank control group. The cells in TGF-β(1) stimulation group were stimulated with 10 μL TGF-β(1) in the mass concentration of 1 mg/μL, while the cells in blank control group were stimulated with the equal volume of phosphate buffer solution. After 72 hours in culture, partial cells in both groups were collected for transcriptome sequencing. The genes with differential expression ratio greater than or equal to 2 and P<0.01 between the two groups were selected to perform enrichment analysis and analysis of metabolic pathways of the Kyoto Gene and Genome Encyclopedia with, and the expression value of Meox1 per million transcripts (TPM) was recorded (n=3). Partial cells from the two groups were used to detect the Meox1 mRNA expression by real-time fluorescent quantitative reverse transcription polymerase chain reaction (RT-PCR) (n=3). (2) Cultured HDF-a cells in the logarithmic growth phase (the same growth phase of cells below) were divided into empty plasmid group, Smad2 overexpression (OE) group, Smad3 OE group, and Smad4 OE group, which were transfected respectively with 2 μg empty pcDNA3.1 plasmid and pcDNA3.1 plasmids separately carrying Smad2, Smad3, and Smad4 for 6 hours, and then were routinely cultured for 48 hours. The Meox1 mRNA expression in the transfected cells of each group was detected by real-time fluorescent quantitative RT-PCR (n=3). (3) HDF-a cells were routinely cultured and grouped the same as in experiment (1). After 72 hours in culture, the enrichment of Smad2, Smad3, and Smad4 protein on the Meox1 promoter in the cells of each group was detected by chromatin immunoprecipitation-quantitative PCR (ChIP-qPCR) (n=3). (4) HDF-a cells were routinely cultured and divided into negative interference group, small interference RNA (siRNA)-Smad2 group, siRNA-Smad3 group, siRNA-Smad4 group, empty plasmid group, Smad2 OE group, Smad3 OE group, and Smad4 OE group, which were transfected respectively with 50 μmol/L random siRNA, siRNA-Smad2, siRNA-Smad3, siRNA-Smad4, 2 μg empty pcDNA3.1 plasmid and pcDNA3.1 plasmids separately carrying Smad2, Smad3, and Smad4 for 6 hours and then routinely cultured for 48 hours. The enrichment of Smad2, Smad3, and Smad4 protein on the Meox1 promoter in the cells of corresponding group was detected by ChIP-qPCR (n=3). (5) Two batches of HDF-a cells were cultured and divided into negative interference group, siRNA-Meox1 group, empty plasmid group, and Meox1 OE group, which were transfected respectively with 50 μmol/L random siRNA, siRNA-Meox1, 2 μg empty pcDNA3.1 plasmid and pcDNA3.1 plasmid carrying Meox1 for 6 hours and then routinely cultured for 24 hours. One batch of cells were subjected to scratch test with the scratch width being observed 24 hours after scratching and compared with the initial width for scratch wound healing; the other batch of cells were subjected to Transwell assay, in which the migrated cells were counted after being routinely cultured for 24 hours (n=3). (6) From January 2018 to June 2019, 3 hypertrophic scar patients (2 males and 1 female, aged 35-56 years) were admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University) 8-12 months after burns. The scar tissue and normal skin tissue along the scar margin resected during surgery were taken, and immunohistochemical staining was performed to observe the distribution of Meox1 protein expression. Data were statistically analyzed with one-way analysis of variance and independent sample t test. Results: (1) After 72 hours in culture, a total of 843 genes were obviously differentially expressed between the two groups, being related to tissue repair, cell migration, inflammatory cell chemotaxis induction process and potential signaling pathways such as tumor necrosis factor, interleukin 17, extracellular matrix receptor. The TPM value of Meox1 in the cells of blank control group was 45.9±1.9, which was significantly lower than 163.1±29.5 of TGF-β(1) stimulation group (t=6.88, P<0.01) with RNA-sequencing. After 72 hours in culture, the Meox1 mRNA expression levels in the cells of blank control group was 1.00±0.21, which was significantly lower than 11.00±3.61 of TGF-β(1) stimulation group (t=4.79, P<0.01). (2) After 48 hours in culture, the Meox1 mRNA expression levels in the cells of Smad2 OE group, Smad3 OE group, and Smad4 OE group were 198.70±11.02, 35.47±4.30, 20.27±2.50, respectively, which were significantly higher than 1.03±0.19 of empty plasmid group (t=31.07, 13.80, 13.12, P<0.01). (3) After 72 hours in culture, the enrichment of Smad2, Smad3, and Smad4 protein on the promoter of Meox1 in the cells of TGF-β(1) stimulation group was significantly higher than that of blank control group respectively (t=12.99, 41.47, 29.10, P<0.01). (4) After 48 hours in culture, the enrichment of Smad2 protein on the promoter of Meox1 in the cells of negative interference group was (0.200 000±0.030 000)%, significantly higher than (0.000 770±0.000 013)% of siRNA-Smad2 group (t=11.67, P<0.01); the enrichment of Smad2 protein on the promoter of Meox1 in the cells of empty plasmid group was (0.200 000±0.040 000)%, significantly lower than (0.700 000±0.090 000)% of Smad2 OE group (t=8.85, P<0.01). The enrichment of Smad3 protein on the promoter of Meox1 in the cells of negative interference group was (0.500 0±0.041 3)%, significantly higher than (0.006 0±0.001 3)% of siRNA-Smad3 group (t=17.79, P<0.01); the enrichment of Smad3 protein on the promoter of Meox1 in the cells of empty plasmid group was (0.470 0±0.080 0)%, which was significantly lower than (1.100 0±0.070 0)% of Smad3 OE group (t=9.93, P<0.01). The enrichment of Smad4 protein on the promoter of Meox1 in the cells of negative interference group was similar to that of siRNA-Smad4 group (t=2.11, P>0.05); the enrichment of Smad4 protein on the promoter of Meox1 in the cells of empty plasmid group was similar to that of Smad4 OE group (t=0.60, P>0.05). (5) Twenty-four hours after scratching, the scratch healing width of cells in siRNA-Meox1 group was narrower than that of negative interference group, while that of Meox1 OE group was wider than that of empty plasmid group. After 24 hours in culture, the number of migration cells in negative interference group was significantly higher than that in siRNA-Meox1 group (t=9.12, P<0.01), and that in empty plasmid group was significantly lower than that in Meox1 OE group (t=8.99, P<0.01). (6) The expression of Meox1 protein in the scar tissue was significantly higher than that in normal skin of patients with hypertrophic scars. Conclusions: TGF-β(1) transcriptionally regulates Meox1 expression via Smad2/3 in HDF-a cells, thus promoting cell migration.
