Abstract
Objective: To analyze the characteristics of cervical lymph node metastasis in tongue squamous cell carcinoma (TSCC). Methods: A retrospective study was conducted. A total of 329 patients with TSCC who underwent en bloc resection of primary tumor and neck dissection in the Second Xiangya Hospital of Central South University from June 2010 to March 2018 were included. There were 283 males and 46 females, aged from 26 to 80 years. All patients underwent the modified neck dissection. The main difference between the modified neck dissection and the traditional neck dissection lay in the managements of unconventional lymph nodes. The lymphatic adipose tissues adjacent to the superior thyroid artery, the base of facial artery and the branches of external carotid artery were thoroughly dissected. The primary tumor as well as lingual artery, tissues along the lingual artery and lymph nodes in the mouth floor were resected. χ2 test was used for comparison of count data, and linear regression model was used for multivariate analysis. Results: Cervical lymph node metastases were found in 136 patients (41.3%). Among 142 patients (T1-2cN0) with supraomohyoid neck dissection, 22 patients had pathologically occult lymph node metastases (15.5%), with a 5-year overall survival rate of 90.2%, which was similar to the 5-year overall survival rate of 92.1% in 120 patients without lymph node metastasis (χ2=0.156, P=0.693). Multivariate linear regression analysis showed that T stage, clinical stage and unconventional lymph node metastasis were important factors for cervical lymph node metastasis in tongue cancer patients (P<0.05). Unconventional lymph node metastases occurred in 30 patients (9.1%), including the metastases of lymph nodes in the floor of mouth (3.0%), the lingual artery (2.4%), the base of the external maxillary artery (2.1%), the superior thyroid artery (0.9%), and the external carotid artery (0.6%). There were significant differences in the unconventional lymph node metastasis rates between patients with negative and positive conventional lymph node metastases [4.9%(10/203) vs. 15.9%(20/126), χ2=11.242, P=0.001] and also between patients with depth of invasion ≤5 mm, 5 mm 10 mm [3.1%(2/64) vs. 5.7%(6/106) vs. 13.8%(22/159), χ2=7.907, P=0.005]. Conclusion: Supraomohyoid neck dissection can achieve reliable control efficacy in patients with cN0 tongue cancer. All patients with lymph node dissection should undergo unconventional lymph node dissection. Unconventional lymph node dissection is strongly recommended for patients with conventional lymph node metastasis.

Abstract
Neutron-gamma discrimination is a tough and significative in experimental neutrons measurements procedure, especially for low-energy neutrons signal discrimination. In this work, based on the Pulse Shape Discrimination (PSD) and Back-Propagation (BP) artificial neural networks, a neutron-gamma discrimination method is developed to broaden the lower limit of energy threshold with the hidden layer of 20 neurons. Compared with neutron-gamma discrimination method based on PSD only, the developed neutron-gamma discrimination method based on the PSD and BP-ANN can discriminate neutron and gamma-ray signals with low energy threshold, which can discriminate signals up to 99.93%. Moreover, this work can reduce the energy threshold from 350 keV to 70 keV, as well as the acquired data utilization increased from 60% to more than 99.9%, which overcome the hardware limitations and distinguish neutron and gamma-ray signals, effectively. The developed neutron-gamma discrimination method and the trained neural network can be directly used to other experimental neutrons measurements.

Abstract
Utilizing the first in-human functional ultrasound imaging (fUSI) of the spinal cord, we demonstrate the integration of spinal functional responses to electrical stimulation. We record and characterize the hemodynamic responses of the spinal cord to a neuromodulatory intervention commonly used for treating pain and increasingly used for the restoration of sensorimotor and autonomic function. We found that the hemodynamic response to stimulation reflects a spatiotemporal modulation of the spinal cord circuitry not previously recognized. Our analytical capability offers a mechanism to assess blood flow changes with a new level of spatial and temporal precision in vivo and demonstrates that fUSI can decode the functional state of spinal networks in a single trial, which is of fundamental importance for developing real-time closed-loop neuromodulation systems. This work is a critical step toward developing a vital technique to study spinal cord function and effects of clinical neuromodulation.

Abstract
BACKGROUND The incidence of early-onset colorectal cancer (EOCRC; diagnosed <50 years of age) is rising globally; however, the causes underlying this trend are largely unknown. CRC has strong genetic and environmental determinants, yet common genetic variants and causal modifiable risk factors underlying EOCRC are unknown. We conducted the first EOCRC-specific genome-wide association study (GWAS) and Mendelian randomization (MR) analyses to explore germline genetic and causal modifiable risk factors associated with EOCRC. PATIENTS AND METHODS We conducted a GWAS meta-analysis of 6176 EOCRC cases and 65 829 controls from the Genetics and Epidemiology of Colorectal Cancer Consortium (GECCO), the Colorectal Transdisciplinary Study (CORECT), the Colon Cancer Family Registry (CCFR), and the UK Biobank. We then used the EOCRC GWAS to investigate 28 modifiable risk factors using two-sample MR. RESULTS We found two novel risk loci for EOCRC at 1p34.1 and 4p15.33, which were not previously associated with CRC risk. We identified a deleterious coding variant (rs36053993, G396D) at polyposis-associated DNA repair gene MUTYH (odds ratio 1.80, 95% confidence interval 1.47-2.22) but show that most of the common genetic susceptibility was from noncoding signals enriched in epigenetic markers present in gastrointestinal tract cells. We identified new EOCRC-susceptibility genes, and in addition to pathways such as transforming growth factor (TGF) β, suppressor of Mothers Against Decapentaplegic (SMAD), bone morphogenetic protein (BMP) and phosphatidylinositol kinase (PI3K) signaling, our study highlights a role for insulin signaling and immune/infection-related pathways in EOCRC. In our MR analyses, we found novel evidence of probable causal associations for higher levels of body size and metabolic factors-such as body fat percentage, waist circumference, waist-to-hip ratio, basal metabolic rate, and fasting insulin-higher alcohol drinking, and lower education attainment with increased EOCRC risk. CONCLUSIONS Our novel findings indicate inherited susceptibility to EOCRC and suggest modifiable lifestyle and metabolic targets that could also be used to risk-stratify individuals for personalized screening strategies or other interventions.

Abstract
Global riverine nitrogen (N) and phosphorus (P) transport models offer important insights into basin nutrient cycling. However, appropriate model selection for a given research objective remains ambiguous. This study conducted a meta-analysis to evaluate the performance and applicability of three prevalent global riverine nutrient transport models: Global NEWS, IMAGE-GNM, and WorldQual. According to performance criteria (satisfactory: R2 > 0.50 and NSE > 0.50), the Global NEWS model performs satisfactorily in simulating dissolved organic nitrogen (DON; n = 101, R2 = 0.58, NSE = 0.57) and dissolved organic phosphorus loads (DOP; n = 80, R2 = 0.59, NSE = 0.59). The model falls short in simulating dissolved inorganic nitrogen (DIN; n = 644, R2 = 0.56, NSE = - 0.80) and dissolved inorganic phosphorus loads (DIP; n = 450, R2 = 0.33, NSE = - 0.12). The IMAGE-GNM model shows satisfactory accuracies in simulating riverine total nitrogen (TN; n = 831, R2 = 0.56, NSE = 0.53) and total phosphorus (TP; n = 902, R2 = 0.59, NSE = 0.48) concentrations, particularly in European basins. The WorldQual model presented unsatisfactory performance in simulating riverine TN (n = 11, R2 = 0.76, NSE = 0.34) and TP (n = 13, R2 = 0.71, NSE = - 0.25) concentrations. Using a two-segment linear model, we recommend the Global NEWS model for basins larger than 2.2 × 104 km2 for DIN and 3.2 × 104 km2 for DIP. The IMAGE-GNM model is best suited for basins with long-term datasets and high latitudes (TN > 21 years and > 53.8 °N; TP > 22 years and > 54.5 °N). For model improvements, both the Global NEWS and WorldQual models could benefit from enhanced in-stream nutrient retention/release modules. The Global NEWS model could be further improved with a better chemical weathering module. For the IMAGE-GNM model, refining the soil erosion module is warranted to enhance model performance. Addressing legacy nutrient effects is crucial for all three models. This study provides valuable guidance for selecting and improving nutrient transport models based on specific research needs.

Abstract
Safety assessment and threat evaluation are crucial for animals to live and survive in the wilderness. However, neural circuits underlying safety assessment and their transformation to mediate flexibility of fear-induced defensive behaviors remain largely unknown. Here, we report that distinct neuronal populations in mouse anterior cingulate cortex (ACC) encode safety status by selectively responding under different contexts of auditory threats, with one preferably activated when an animal staysing in a self-deemed safe zone and another specifically activated in more dangerous environmental settings that led to escape behavior. The safety-responding neurons preferentially target the zona incerta (ZI), which suppresses the superior colliculus (SC) via its GABAergic projection, while the danger-responding neurons preferentially target and excite SC. These distinct corticofugal pathways antagonistically modulate SC responses to threat, resulting in context-dependent expression of fear reactions. Thus, ACC serves as a critical node to encode safety/danger assessment and mediate behavioral flexibility through differential top-down circuits.

Abstract
The conventional confirmation tests of tuberculous meningitis (TBM) are usually low in sensitivity, leading to high TBM mortality. Hence, sensitive methods for indicating the presence of bacilli are required. Tuberculostearic acid (TBSA), a constituent from Mycobacterium tuberculosis had been evaluated as a promising marker, but fails to demonstrate consistent results for definite TBM. This study retrospectively reviewed medical records of 113 TBM suspects, constructing a TBSA-combined scoring system based on multiple factors, which show sensitivity and specificity of 0.8148 and 0.8814, respectively, and the area under the receiver operating characteristic curve of 0.9010. Multivariate analyses revealed four co-predictive factors strongly associated with TBSA: extra-neural tuberculosis, basal meningeal enhancement, CSF glucose/Serum glucose <0.595, and coinfection in CNS (Total). The subsequent machine learning-based validation showed correspondent importance to factors in the TBSA model. This study demonstrates a simple scoring system to facilitate TBM prediction, yield reliable diagnoses and allow timely treatment initiation.

Abstract
PURPOSE/OBJECTIVE(S) Thoracic irradiation involves large blood vessels and hematopoietic tissues which was easily inducing lymphopenia. Lymphocytes are important components of immune response and lymphopenia is associated with poorer survival. However, the dynamic recovery of lymphocyte subsets after thoracic irradiation were rarely reported in the literature. This study focused on dynamic changes of lymphocytes subsets of mice after receiving thoracic irradiation in and out of radiation field. MATERIALS/METHODS C57BL/6 male mice aged 6-8 weeks received 2Gy*5fx whole thoracic irradiation and were sacrificed on the 1 day, 7 days, 15 days, 25 days after irradiation. Peripheral blood was harvested for mature lymphocyte subsets (B cells, T cells, CD4+T cells, CD8+T cells, NK cells) detection by performing flow cytometry, while thymus, femur bone marrow and sternal bone marrow for hematopoietic stem cells (Long-term Hematopoietic Stem Cell [LT-HSC], Short-term Hematopoietic Stem Cell [ST-HSC]) and progenitor cells (Multipotent Progenitor [MPP], Common Lymphoid Progenitor [CLP]). Absolute counts method was used in flow cytometry and data analysis were performed by scientific 2-D graphing and statistics software. RESULTS We found that the lymphocyte subsets were significantly reduced in peripheral blood of irradiated mice (all p<0.05). The mature lymphocyte subsets returned to normal 2-3 weeks after irradiation. After radiation, thymus weight was significantly decreased (p<0.0001). With the recovery of thymus weight, the number of hematopoietic stem cells returned to the baseline. For the femur bone marrow (out of the radiation field), hematopoietic stem cells and progenitor cells showed a proliferation tendency. MPP significantly increased in the 1day after irradiation (p = 0.0347) and LT-HSC increased in the 8 days (p = 0.0011). However, although ST-HSC and CLP were slightly increased after irradiation, there were no statistically significance. The sternal bone marrow (in the radiation field) reached the lowest value 1day after irradiation (all p<0.0001). Although hematopoietic stem cells and progenitor cells recovered gradually, but still far away from the level of the control group (all p<0.05). CONCLUSION The recovery of lymphocytes in the peripheral blood might mainly come from the supplement of bone marrow out of the irradiation field, while bone marrow in the field suffered serious destruction which did slightly help for lymphocytes recovery.

Abstract
PURPOSE/OBJECTIVE(S) Lymphocytes play a critical role in anti-tumor, and are highly sensitive to radiation. However, the dynamic changes of lymphocytes subsets after receiving thoracic radiotherapy have rarely been investigated. This study was to explore the recovery characteristics of each subset, and the role of thymosin α1 after thoracic radiotherapy. MATERIALS/METHODS A total of 252 patients receiving chest radiotherapy included in this study. Blood was harvested before, at the end of radiotherapy, 1 month, 4 months, 7 months, 10 months, 13 months, and 19 months after radiotherapy for lymphocyte subsets detection by performing flow cytometry. In addition, a total of 26 patients with thoracic malignancy were treated with thymosin α1 after radiotherapy for one month. The number of lymphocyte subsets at the end of 1 month after radiotherapy were compared with control group. Absolute counts method was used in flow cytometry. RESULTS At the end of radiotherapy, nearly all of the subsets decreased significantly (T cell: 65.4%, Tc cell: 64.8%, Th cell: 66.1%, B cell: 88.7%, NK cell: 68.8%), except Treg cell. Tc cells recovered rapidly to baseline level at 1 month. The number of NK cells increased by 1.95 times at 1 month, and recovered to baseline level at 7th month. The number of B cell at 1 month was still 19.2% compared baseline, and recovered slowly to baseline at 7th month. The number of Th cells were nearly no recovery, and were 44.1% compared with baseline even at 19th month. For patients with thymosin α1 injection, all of the lymphocyte subsets had no significant difference compared those without thymosin α1 injection. In addition, younger patients were with better recovery in Th cells (p = 0.011) and B cells (p < 0.001) than elder patients at 1 month. CONCLUSION B cell was the most radiosensitive lymphocyte, and Th cell was continuous exhaustion after thoracic radiation. Thymosin α1 had no effect on lymphocyte subpopulation recovery, and new drugs are urgently needed to explore in the future.

Abstract
OBJECTIVE Although many observational studies have shown an association between rosiglitazone and cardiovascular disease (CVD) or risk factors, controversy remains. We conducted a Mendelian randomized (MR) study to explore whether rosiglitazone is causally related to CVDs and risk factors. PATIENTS AND METHODS Single-nucleotide polymorphisms associated with rosiglitazone at genome-wide significance were identified from a genome-wide association study of 337,159 European-ancestry individuals. Four treatments with rosiglitazone-associated single-nucleotide polymorphisms associated with a higher risk of CVDs were used as an instrumental variable (IV). Summary-level data for 7 CVDs and 7 risk factors were obtained from UK Biobank and consortia. RESULTS We found no causal effects of rosiglitazone, either on CVDs or risk factors. The results were consistent in sensitivity analyses using Cochran's Q test, MR-PRESSO method, leave-one-out analysis and Mendelian randomization-Egger method (MR-Egger), and no directional pleiotropy was observed. Sensitivity analyses confirmed that rosiglitazone was not significantly associated with CVDs and risk factors. CONCLUSIONS The findings from this MR study indicate no causal relationship between rosiglitazone and CVDs or risk factors. Hence, previous observational studies may have been biased.

Abstract
Lipid peroxidation is a process that occurs in cells when they are exposed to oxidative stress. During the process reactive oxygen species attack lipids within the lipid bilayers of cells. Since the products of lipid peroxidation are toxic and carcinogenic, it is important to understand where and how it occurs with nanoscale resolution. The radical intermediates of this process are particularly interesting since they are causing chain reactions damaging large parts of the lipid membranes in cells. However, they are also difficult to measure for the state of the art because they are short lived and reactive. Here, we study the lipid peroxidation of three artificial lipid bilayers on a diamonds substrate that can be used to study lipid peroxidation. In particular, we present a diamond quantum sensing method called T1-relaxometry that allows for in situ measurements and imaging of radical intermediates of lipid peroxidation in these membranes.

Abstract
Increasing evidence indicates that groundwater can contain high dissolved phosphorus (P) concentrations, thereby contributing as a potential pollution source for surface waters. However, limited quantitative knowledge is available concerning groundwater P fluxes to rivers. Based on monthly hydrochemical monitoring data for rivers and groundwater in 2017-2020, this study combined baseflow separation methods and a load apportionment model (LAM) to quantify contributions from point sources, surface runoff, and groundwater/subsurface runoff to riverine P pollution in a typical agricultural watershed of eastern China. In the studied Shuanggang River, most total P (TP) and dissolved P (DP) concentrations exceeded targeted water quality standards (i.e., TP ≤ 0.2 mg P L-1, DP ≤ 0.05 mg P L-1), with DP (76 ± 20%) being the major riverine P form. Observed DP concentrations in groundwater were generally higher than those of river waters. There was a strong correlation between river and groundwater P concentrations, implying that groundwater might be a considerable P pollution source to rivers. The nonlinear reservoir algorithm estimated that baseflow/groundwater contributed 66-68% of monthly riverine water discharge on average, which was consistent with results estimated by an isotope-based sine-wave fitting method. The LAM incorporating point sources, surface runoff, and groundwater effectively predicted daily riverine TP [calibration: coefficient of determination (R2) = 0.76-0.82, Nash-Sutcliffe Efficiency (NSE) = 0.61-0.77; validation: R2 = 0.88-0.98, NSE = 0.54-0.64] and DP loads (calibration: R2 = 0.73-0.84, NSE = 0.67-0.72; validation: R2 = 0.88-0.97, NSE = 0.56-0.83). The LAM estimated point source, surface runoff, and groundwater contributions to riverine loads were 15-18%, 14-35%, and 46-70% for TP loads and 7-9%, 10-32%, and 59-82% for DP loads, respectively. Groundwater was the dominant riverine P source due to long-term accumulation of P from excess fertilizer and farmyard manure applications. The developed methodology provides an alternative method for quantifying P pollution loads from point sources, surface runoff, and groundwater to rivers. This study highlights the importance of controlling groundwater P pollution from agricultural lands to address riverine water quality objectives and further implies that decreasing fertilizer P application rates and utilizing legacy soil P for crop uptake are required to reduce groundwater P loads to rivers.

Abstract
Graphene is a promising active material for electric double layer supercapacitors (EDLCs) due to its high electric conductivity and lightweight nature. However, for practical uses as a power source of electronic devices, a porous structure is advantageous to maximize specific energy density. Here, we propose a facile fabrication approach of mesoporous graphene (m-G), in which self-assembled mesoporous structures of poly(styrene)-block-poly(2-vinylpyridine) copolymer (PS-b-P2VP) are exploited as both mesostructured catalytic template and a carbon source. Notably, the mesostructured catalytic template is sufficient to act as a rigid support without structural collapse, while PS-b-P2VP converts to graphene, generating m-G with a pore diameter of ca. 3.5 nm and high specific surface area of 186 m2/g. When the EDLCs were prepared using the obtained m-G and ionic liquids, excellent electrochemical behaviors were achieved even at high operation voltages (0 ∼ 3.5 V), including a large specific capacitance (130.2 F/g at 0.2 A/g), high-energy density of 55.4 W h/kg at power density of 350 W/kg, and excellent cycle stability (>10,000 cycles). This study demonstrates that m-G is a promising material for high-performance energy storage devices.

Abstract
Objective: To investigate the efficacy of anterolateral thigh flap preforming tongue in patients with total glossectomy. Methods: A total of 27 patients with tongue cancer who underwent total glossectomy, neck lymph node dissection and anterolateral thigh flap transfer were collected from January 2019 to April 2021 in the Department of Oral and Maxillofacial Surgery at the Second Xiangya Hospital. All patients were males, the age ranged from 35-73 years. The patients were divided into experimental (14 cases) and control (13 cases) groups, based on whether the tongue was reconstructed. The clinical parameters of two groups were analyzed by independent sample t test or Fisher exact probability method. Results: The success rate of free flap was 100%, of the patients, 2 patients had cervical hematoma and 1 patient had wound infection postoperatively. There was no difference in speech (6.69±3.42 vs. 5.50±3.01, t=0.96, P=0.346) or swallowing (χ2=0.46, P=0.793) function between two groups at 1 month after surgery. However, the speech (24.94±7.43 vs. 18.44±6.30, t=2.48, P=0.020) and swallowing (χ2=6.97, P=0.008) functions in experimental group were significantly better than those in control group. No case was lost to follow-up. All patients were extubated after operation, with average time of 7.2 days in the experimental group and 7.7 days in the control group. The overall survival rate was 71.4% in the experimental group and 61.5% in the control group. Conclusion: The use of anterolateral thigh flap preforming tongue can improve the speech and swallowing functions in patients with total glossectomy and offer a novel method for tongue construction.

Abstract
OBJECTIVE Primary central nervous system (CNS) cancer is a predominant source of mortality and morbidity globally. This study aims to analyze the burden and variation trends of CNS cancer in China from 1990 to 2019. MATERIALS AND METHODS In this cross-sectional study, we analyzed people of all ages with CNS cancer in China from January 1, 1990, to December 31, 2019. We collected the data including incidence, deaths, and disability-adjusted life-years (DALYs) from the Global Burden of Disease (GBD) study 2019. The age-standardized incidence rate (ASIR), age-standardized death rate (ASDR), and DALYs rate were compared by age and sex. RESULTS In 2019, there were more than 94 (95% uncertainty intervals [CI]: 73-114) thousand incident cases, 63 (47-76) thousand deaths and 2.0 (1.5-2.5) million DALYs due to CNS cancer in China in 2019. From 1990 to 2019, the absolute number of incident cases, deaths, and DALYs increased by 107.0% (39.0 to 169.0), 67.0% (12.0 to 117.0), and 16.0% (-23.0 to 63.0). The ASIR increased by 28.0% (-16.0 to 64.0). ASDR and age-standardized DALYs rate decreased by -10.0% (-40.0 to 15.0) and -22.0% (-50.0 to 10.0), respectively. CONCLUSIONS The overall burden due to CNS cancer in China remains high, as evidenced by the sharp increase in the incident cases, deaths, and DALYs from 1990 to 2019. Elderly patients and neonates show relatively high burden. Sex-specific differences in the incidence of CNS cancer in China are observed.

Abstract
Free radical generation plays a key role in viral infections. While free radicals have an antimicrobial effect on bacteria or fungi, their interplay with viruses is complicated and varies greatly for different types of viruses as well as different radical species. In some cases, radical generation contributes to the defense against the viruses and thus reduces the viral load. In other cases, radical generation induces mutations or damages the host tissue and can increase the viral load. This has led to antioxidants being used to treat viral infections. Here we discuss the roles that radicals play in virus pathology. Furthermore, we critically review methods that facilitate the detection of free radicals in vivo or in vitro in viral infections.

Abstract
OBJECTIVE To explore the influence of nutritional status on 90-day functional outcomes of stroke patients with acute large vessel occlusion in the anterior circulation after endovascular treatment (EVT). METHODS We retrospectively analyzed the baseline, laboratory, surgical and 90-day follow-up data of patients with stroke resulting from acute large vessel occlusion in the anterior circulation, who underwent emergency endovascular treatment in our hospital from July, 2015 to December, 2020. A favorable outcome was defined as a modified Rankin scale score ≤2 at 90 days. Univariate and multivariate regression analyses were performed to explore the relationship between nutritional status and 90-day functional outcomes of the patients. RESULTS A total of 459 patients (mean age of 68.29±11.21 years, including 260 males) were enrolled in this study. According to their prognostic nutritional index (PNI), the patients were divided into normal nutrition group (392 cases, 85.4%), moderate malnutrition group (44 cases, 9.6%), and severe malnutrition group (23 cases, 5.0%). Univariate analysis showed that the patients with good clinical outcomes had a lower proportion of malnutrition with a younger age, a lower rate of diabetes, lower baseline blood pressure, lower baseline NIHSS score, higher baseline ASPECT score, and higher rates of good collateral circulation and complete vascular recanalization. Multivariate analysis showed that in addition to age, diabetes, baseline systolic blood pressure, successful recanalization, baseline ASPECT score, baseline NIHSS score and collateral circulation, a greater PNI was a protective factor for a good 90-day outcome of patients after EVT (moderate vs severe: OR=0.245, 95% CI: 0.066-0.908, P=0.035; normal vs severe: OR=0.185, 95% CI: 0.059-0.581, P=0.004). CONCLUSION Nutritional status an important factor affecting the 90-day outcomes after EVT of stroke patients with acute large vessel occlusion in the anterior circulation.

Abstract
Objective: BMI may play a protective role in reducing the mortality rate of patients with chronic obstructive pulmonary disease (COPD), but its effect on acute exacerbation of COPD remain unclear. Methods: Subjects were selected from the COPD patients registration system established in 2014 in Pudong new district, Shanghai. COPD patients from 8 communities were selected by cluster sampling and follow up was conducted prospectively for 18 months. Basic information and BMI were obtained from baseline survey, and acute exacerbations were collected during follow-up. The association between BMI and risk of acute exacerbation was evaluated by using multiple negative binomial regression. Results: Among 328 community COPD patients, 295 who completed the follow up were included in the analysis, in whom 96.3% (284/295) were mild COPD patients. During the follow-up, 11.1% (33/295) of the patients reported acute exacerbation. The results of multiple negative binomial regression suggested that, the risk for acute exacerbation decreased with the increase of BMI (IRR=0.85, 95%CI:0.73-0.98), overweight patients with BMI ≥25.0 kg/m2 (IRR=0.36, 95%CI:0.13-0.91) or moderate BMI (T2 vs. T1, IRR=0.31, 95%CI:0.11-0.77) had lower risk for acute exacerbation compared with the patients with normal or low BMI. BMI had a linear correlation with the risk of acute exacerbation. Conclusion: The risk for acute exacerbation in patients with mild or moderate COPD in communities decreased with the increase of BMI, and being overweight might be a protective factor for the acute exacerbation of COPD.

Abstract
Objective: To explore the applicability of three different kinds of noise occupational health risk assessment methods to the occupational health risk assessment of noise exposed positions in an automobile foundry enterprise. Methods: In July 2020, the occupational-health risk assessment of noise-exposed positions was conducted by using the Guidelines for risk management of occupational noise hazard (guideline method) , the International Commission on Mining and Metals Guidelines for Occupational Health Risk Assessment (ICMM) method and the Occupational-health risk index method (index method) respectively, and the results were analyzed and compared. Results: Through the occupational health field investigation, the noise exposure level of the enterprise's main workstations was between 80.3 and 94.8 dB (A) , among which the noise of the posts of shaking-sand, cleaning and modeling was greater than 85 dB (A) ; The noise risk of each position was evaluated by the three methods, and the adjustment risk level was between 2 and 5 assessed using the guideline method, between 2 and 3 assessed using the index method, and 5 evaluated using the ICMM model. Conclusion: Each of the three risk assessment methods has its own advantages and disadvantages. The ICMM model has a large difference in value assignment, and values in the results are larger than expected. The evaluation results of the guideline method and the index method are consistent in some positions, there is certain subjectivity in the evaluation using the index method, and the guideline method is more objective.

Abstract
Children with cerebral palsy (CP) present a higher prevalence and severity of caries. Although researchers have studied multiple risk factors for caries in CP, the role of microorganisms in caries remains one of the critical factors worth exploring. In order to explore the differences in the supragingival plaque microbiota (SPM), supragingival plaque samples were collected from 55 CP children and 23 non-CP children for 16S rRNA sequencing. Distinct SPM composition was found between CP children with severe caries (CPCS) and non-CP children with severe caries (NCPCS). Further subanalysis was also done to identify if there were any differences in SPM among CP children with different degrees of caries, namely, caries-free (CPCF), mild to moderate caries (CPCM), and severe caries (CPCS). After selecting the top 15 most abundant species in all groups, we found that CPCS was significantly enriched for Fusobacterium nucleatum, Prevotella intermedia, Campylobacter rectus, Porphyromonas endodontalis, Catonella morbi, Alloprevotella tannerae, Parvimonas micra, Streptobacillus moniliformis, and Porphyromonas canoris compared to NCPCS. By comparing CPCF, CPCM, and CPCS, we found that the core caries-associated microbiota in CP children included Prevotella, Alloprevotella, Actinomyces, Catonella, and Streptobacillus, while Capnocytophaga and Campylobacter were dental health-associated microbiota in CP children. Alpha diversity analysis showed no significant difference between NCPCS and CPCS, but the latter had a much simpler core correlation network than that of NCPCS. Among CP children, CPCM and CPCF displayed lower bacterial diversity and simpler correlation networks than those of CPCS. In summary, the study showed the specific SPM characteristics of CPCS compared to NCPCS and revealed the core SPM in CP children with different severities of caries (CPCF, CPCM, and CPCS) and their correlation network. Hopefully, the study would shed light on better caries prevention and therapies for CP children. Findings from the current study offer exciting insights that warrant larger cohort studies inclusive of saliva and feces samples to investigate the potential pathogenic role of oral microbiota through the oral–gut–brain axis in CP children with caries.

Abstract
Objective: Patients with advanced gastric cancer have a poor prognosis and a possibility of peritoneal metastasis even if receiving gastrectomy. Hyperthermic intraperitoneal chemotherapy (HIPEC) can effectively kill free cancer cells or small lesions in the abdominal cavity. At present, preventive HIPEC still lacks safety evaluation in patients with locally advanced gastric cancer. This study aims to explore the safety of radical resection combined with HIPEC in patients with locally advanced gastric cancer. Methods: A descriptive case series study was carried out. Clinicopathological data of 130 patients with locally advanced gastric cancer who underwent radical resection + HIPEC at the Department of Gastrointestinal Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2020 to February 2021 were retrospectively analyzed. Inclusion criteria: (1) locally advanced gastric adenocarcinoma confirmed by postoperative pathology; (2) no distant metastasis was found before surgery; (3) radical resection; (4) at least one HIPEC treatment was performed. Exclusion criteria: (1) incomplete clinicopathological data; (2) tumor metastasis was found during operation; (3) concomitant with other tumors. HIPEC method: all the patients received the first HIPEC immediately after D2 radical resection, and returned to the ward after waking up from anesthesia; the second and the third HIPEC were carried out according to the patient's postoperative recovery and tolerance; interval between two HIPEC treatments was 48 h. Observation indicators: (1) basic information, including gender, age, body mass index, etc.; (2) treatment status; (3) perioperative adverse events: based on the standard of common adverse events published by the US Department of Health and Public Health (CTCAE 5.0), the adverse events of grade 2 and above during the treatment period were recorded, including hypoalbuminemia, bone marrow cell reduction, wound complications, abdominal infection, lung infection, gastroparesis, anemia, postoperative bleeding, anastomotic leakage, intestinal obstruction, pleural effusion, abdominal distension, impaired liver function, and finally a senior professional title chief physician reviewed the above adverse events and made a safety evaluation of the patient; (4) association between times of HIPEC treatment and adverse events in perioperative period; (5) analysis of risk factors for adverse events in perioperative period. Results: Among the 130 patients, 79 were males and 51 were females with a median age of 59 (54, 66) years and an average body mass index of (23.9±7.4) kg/m(2). The tumor size was (5.4±3.0) cm and 100 patients (76.9%) had nerve invasion. All the 130 patients received radical resection + HIPEC and 125 (96.2%) patients underwent laparoscopic surgery. The mean operative time was (345.6±52.3) min and intraoperative blood loss was (82.0±36.5) ml. One HIPEC treatment was performed in 54 patients (41.5%), 2 HIPEC treatments were in 57 (43.8%), and 3 HIPEC treatments were in 19 (14.6%). The average postoperative hospital stay was (13.1±7.5) d. A total of 57 patients (43.8%) had 71 cases of postoperative complications of different degrees. Among them, the incidence of hypoalbuminemia was 22.3% (29/130), and the grade 2 and above anemia was 15.4% (20/130), lung infection was 3.8% (5/130), bone marrow cell suppression was 3.7% (4/130), abdominal cavity infection was 2.3% (3/130), and liver damage was 2.3% (3/130), wound complications was 1.5% (2/130), abdominal distension was 1.5% (2/130), anastomotic leakage was 0.8% (1/130), gastroparesis was 0.8% (1/130) and intestinal obstruction was 0.8% (1/130), etc. These adverse events were all improved by conservative treatments. There were no statistically significant differences in the incidence of adverse events during the perioperative period among patients undergoing 1, 2, and 3 times of HIPEC treatments (all P>0.05). Univariate and multivariate logistic analyses showed that age > 60 years (OR: 2.346, 95%CI: 1.069-5.150, P=0.034) and neurological invasion (OR: 2.992, 95%CI: 1.050-8.523, P=0.040) were independent risk factors for adverse events in locally advanced gastric cancer patients undergoing radical resection+HIPEC (both P<0.05). Conclusions: Radical surgery + HIPEC does not significantly increase the incidence of perioperative complications in patients with advanced gastric cancer. The age >60 years and nerve invasion are independent risk factors for adverse events in these patients.

Abstract
Objective: To explore the dose-response relationship between cumulative noise exposure and high-frequency hearing loss, and further to provide a basis for the control of occupational hazards of noise. Methods: A Meta-analysis of dose-response relationships was performed on the data of eligible literatures published in China from January 2000.1 to December 2019.12. Results: The initial combined Odds Ratio (OR) and its 95%CI in the Meta-analysis were 1.10 (1.08-1.12) . As the Begg's funnel plot and Egger's test indicated publication bias (t=5.97, P<0.01) , the Trim-and-Fill Method was used for OR value adjustment. The adjusted-OR was 1.09 (1.07-1.12) ; sensitivity analysis showed that the results of this Meta-analysis have high stability; subgroup analysis indicated that the ORs of the steady-state noise group and the non-steady-state noise group were 1.10 (1.08-1.12) and 1.14 (1.07-1.21) , the ORs of the old standard group and the new standard group were 1.10 (1.08-1.12) and 1.11 (1.00-1.24) , respectively. The nonlinear dose-response relationship curve demonstrated that the risk of high-frequency hearing loss increases rapidly after CNE reaches 95 dB (A) ·years. Conclusion: There is a definite dose-response relationship between CNE and high-frequency hearing loss, which can be used to predict the risk of high-frequency hearing loss in noisy workers.

Abstract
OBJECTIVE Atorvastatin has been suggested to reduce hematoma volume and improve neurological outcomes in patients with chronic subdural hematoma (CSDH). However, the benefits and harms of atorvastatin use after surgery in elderly patients are not well studied. PATIENTS AND METHODS We conducted a retrospective trial to analyze older people (> 60 years) with CSDH, those who were treated with surgical intervention. Patients were assigned to study group if they received oral atorvastatin after surgery at least 1 week, and patients without atorvastatin medication postoperatively were assigned to control group. The primary outcome was the overall rate of recurrence at 1 month after surgery. The main secondary endpoints were the scores on the modified Rankin Scale (mRS), hematoma volume, mortality, and complications after surgery. RESULTS A total of 49 eligible patients were included - 21 in the study group and 28 in the control group. The baseline characteristics were similar between the 2 groups. At 1 month, recurrence of subdual hematoma requiring repeat surgery was reported in 4 of 21 patients (19.0%) in the study group and in 5 of 28 patients (17.9%) in the control group (p=0.915). The hematoma volume was similar between the 2 groups (p=0.979). A favorable outcome (a score of 2 or less on the mRS) occurred in 90.5% of patients in the study group and in 96.4% of those in the control group (p=0.390). CONCLUSIONS In older people with CSDH, postoperative atorvastatin use barely reduces the incidence of recurrence and hematoma volume.

Abstract
Herein, printable polymer series containing different portions of cinnamate and perfluorinated phenyl functionalities, namely, polyperfluorostyrene-co-poly(vinylbenzyl cinnamates) (PFS-co-PVBCi (x:y)) copolymers, were synthesized and applied as gate dielectrics for organic thin-film transistors (OTFTs). The polymeric dielectrics were successfully printed via electrostatic force-assisted dispensing mode of electrohydrodynamic jet printing. The dielectric characteristics of the printed polymers, such as surface energy, dielectric constant, leakage current, atomic depth profiles, and deposited semiconducting layer characteristics, were clearly identified. In particular, the difference in driving stability of OTFTs according to the type of polymer was analyzed in detail and a possible mechanism was proposed. Results suggested that PFS-co-PVBCi (3:7) led to optimized consequences, yielding an almost negligible Vth shift under continuous bias stress. Through this, we successfully implemented flexible OTFT and logic devices using printed PFS-co-PVBCi (3:7) dielectrics with stable operation properties. Therefore, we believe that this study will facilitate the printing and synthesis of polymer dielectrics to produce printed and flexible OTFTs.

Abstract
Estimates of riverine N2O emission contain great uncertainty because of the lack of quantitative knowledge concerning riverine N2O sources and fates. Using a 3.5-year record of monthly N2O measurements from the Yongan River network of eastern China, we developed a mass-balance model to address the riverine N2O source and sink processes. We achieved reasonable model efficacies (R2 = 0.44-0.84, Nash-Sutcliffe coefficients = 0.40-0.80) across three tributaries and the entire river system. Estimated riverine N2O loads originated from groundwater (38-88%), surface runoff (3-26%), and in-stream production (4-48%). Estimated in-stream losses via atmospheric release + complete denitrification accounted for 76, 95, 25, and 89% of riverine N2O fate for the agricultural, residential, forest, and entire river system, respectively. Considering limited complete denitrification, the model estimated an upper-bound riverine N2O emission rate of 2.65 ton N2O-N km-2 year-1 for the entire river system. Riverine N2O emission estimates were of comparable magnitude to those estimated with a power-law scaling model. Riverine N2O emissions using the IPCC default emission factor (0.26%) overestimated emissions by 3-15 times, whereas the dissolved N2O concentration-based emission factor overestimated or underestimated emissions. This study highlights the importance of combining comprehensive information on N2O sources and fates to achieve accurate riverine N2O emission estimates.

Abstract
Objective: To investigate the high-frequency hearing loss (HFHL) of workers in an automobile factory and its influencing factors, so as to provide a scientific basis for occupational health management of noise workers. Methods: From March to July 2019, 2647 workers from an automobile factory were selected as the research objects by cluster sampling method. The basic personal information (such as gender, age, education level, height, weight, etc.) , history of ear disease, the history of detonation, history of exposure to ototoxic drugs, history of exposure to occupational noise, etc., were investigated by questionnaire and occupational health examination. Chi-square test was used to compare the detection rates of HFHL in different populations, and multivariate logistic regression model was used to analyze the influencing factors of HFHL. Results: The noise level of 2647 individual workers ranged from 75.0 dB (A) to 92.0 dB (A) , with an average of (84.14±2.47) dB (A) . The detection rate of HFHL was 17.2% (456/2647) . There were significant differences in the the detection rate of HFHL among workers of different gender, age, educational level, working age, noise exposure level, diabetes history, detonation history, smoking and drinking workers (P<0.05) . Multivariate logistic regression analysis showed that male, age ≥30 years old, smoking and noise exposure were risk factors for HFHL (P<0.05) . Conclusion: The detection rate of HFHL in automobile factory workers is high. Gender, age, smoking and noise are the influencing factors of HFHL. It is necessary to strengthen the noise control in the workplace and guide workers to choose healthy lifestyle.

Abstract
The environmental threshold for upland soil phosphorus (P) content (ETSP, i.e., inflection point of soil P content leading to enhanced P loss) provides an important metric for guiding agricultural nonpoint source P pollution control. This study achieved the first meta-analysis to determine ETSP values for upland soils in China. The estimated national-level ETSP based on 472 field experimental observations of Olsen-P content and P loss rate was 30.1 ± 4.0 mg P kg-1, which was lower than the average ETSP value (52.1 ± 5.0 mg P kg-1) but higher than the average agronomic threshold values (16.0 ± 6.4 mg P kg-1) previously reported. Lower upland ETSP values occurred in acidic soils and soils having higher organic matter content (SOM), precipitation and slope (ETSP: 30.5 for pH < 7.0 versus 46.1 for pH ≥ 7.0; >56.4 for SOM < 2%, 49.9 for SOM = 2%-3%, and <3 for SOM > 3%; 33 for precipitation < 1000 mm yr-1, 27.5 for precipitation = 1000-1200 mm yr-1 and <5 for precipitation > 1200 mm yr-1; and 39.8 for slopes < 5° versus <9 for slopes ≥ 5°). A multiple regression model that incorporates SOM, pH, precipitation and slope was developed to predict upland ETSP values (R2 = 0.73, p < 0.01). The model estimated national upland ETSP values ranging from ~0 to 100 mg P kg-1 with an areal-weighted average of 60.6 mg P kg-1 and 15% of national upland soils having ETSP values <30 mg P kg-1. Upland soil P contents in Guangdong, Fujian and Zhejiang provinces largely exceeded their corresponding ETSP values by 1-22 mg P kg-1, indicating high P loss risks. Controlling upland P loss requires integrated management of soil P content, SOM, pH and erosion control. This study provides the first national estimate of upland soil ETSP, providing critical quantitative information for designing management practices to attenuate agricultural nonpoint source P pollution.
