Abstract
Genetic load refers to the accumulated and potentially life-threatening deleterious mutations in populations. Understanding the mechanisms underlying genetic load variation of transposable element (TE) insertion, a major large-effect mutation, during range expansion is an intriguing question in biology. Here, we used 1,115 global natural accessions of Arabidopsis (Arabidopsis thaliana) to study the driving forces of TE load variation during its range expansion. TE load increased with range expansion, especially in the recently established Yangtze River basin population. Effective population size, which explains 62.0% of the variance in TE load, high transposition rate, and selective sweeps contributed to TE accumulation in the expanded populations. We genetically mapped and identified multiple candidate causal genes and TEs, and revealed the genetic architecture of TE load variation. Overall, this study reveals the variation in TE genetic load during Arabidopsis expansion and highlights the causes of TE load variation from the perspectives of both population genetics and quantitative genetics.

Abstract
Objective: To explore the histopathological factors affecting the stiffness of papillary thyroid carcinoma (PTC). Methods: Ninety-six patients with PTC confirmed by surgery and pathology in Shanxi Bethune Hospital from January 2019 to December 2020 were selected, including 101 nodules. Two-dimensional ultrasound and shear-wave elastography (SWE) were performed before surgery and the average Young's modulus (Emean) of PTC nodules were measured. Histopathological examinations on the nodules were conducted after surgery to decide the lesion size, number of lesions, calcification type, presence or absence of capsular and extracapsular invasion, degree of fibrosis, microvessel density, and number of tumor cells. The correlations between the lesion size, degree of fibrosis, microvessel density, and number of tumor cells and the Emean were analyzed. The Emeans of nodules with different numbers of lesions, presence or absence of capsular and extracapsular invasion, and different pathological calcification types were compared. The multiple linear regression analysis was used to evaluate the histopathological factors influencing the Emean. Results: The ranges of the lesion sizes, degrees of fibrosis, microvascular density, numbers of tumor cells, and the Emeans of the 101 investigated PTC nodules were (1.29±0.95) cm, (30.64±18.37)%, (101.64±30.7) vessels per high power field, (373.52±149.87) cells per high power field, and (36.47±19.62) kPa, respectively. Correlation analysis showed that the lesion size of PTC and the degree of fibrosis were positively correlated with the Emean (r=0.660, P<0.001; r=0.789, P<0.001), while the microvessel density was negatively correlated with the Emean (r=-0.198, P=0.047). The Emean of the group with capsular and extracapsular invasion was higher than that of the group without (P=0.014). There were statistical differences in the Emeans among different types of pathological calcification (P<0.001). The multiple linear regression analysis showed that the lesion size (β=0.325, P<0.001), degree of fibrosis (β=0.563, P<0.001), psammoma bodies (β=0.177, P=0.001), stromal calcification (β=0.164, P=0.003), and mixed calcification of both psammoma bodies and stroma (β=0.163, P=0.003) were independent influencing factors for the Emean. The degree of fibrosis had the greatest impact on the Emean. Conclusions: The Emean of PTC lesions was correlated with the histopathological characteristics of PTC. The lesion size, degree of fibrosis, and calcification had significant impact on the Emean, among which the degree of fibrosis had the greatest impact.

Abstract
We investigated the high energy spin excitations in electron-doped La_{2-x}Ce_{x}CuO_{4}, a cuprate superconductor, by resonant inelastic x-ray scattering (RIXS) measurements. Efforts were paid to disentangle the paramagnon signal from non-spin-flip spectral weight mixing in the RIXS spectrum at Q_{∥}=(0.6π,0) and (0.9π,0) along the (1 0) direction. Our results show that, for doping level x from 0.07 to 0.185, the variation of the paramagnon excitation energy is marginal. We discuss the implication of our results in connection with the evolution of the electron correlation strength in this system.

Abstract
Objective: To compare the efficacy of lower extremity three dimensional CT venography (CTV) and lower extremity ascending phlebography in evaluating recurrent varicose veins. Methods: A retrospective analysis was conducted on clinical data from 235 patients with unilateral recurrent varicose veins who were treated at the Department of Vascular Surgery,Beijing Shijitan Hospital,Capital Medical University, between January 2015 and December 2020.There were 112 males and 123 females, with an age of (62.5±11.4)years (range:24 to 75 years).Patients were stratified into two groups based on preoperative imaging examination:the CTV group (utilizing lower extremity venous ultrasound+lower extremity CTV) and the control group (employing lower extremity venous ultrasound+lower extremity ascending phlebography).The two groups were matched in a 1∶1 ratio using propensity score matching, resulting in 43 cases per group.Comparative analyses between the groups at the one-year postoperative follow-up were performed using independent sample t tests, Wilcoxon rank-sum tests, χ2 tests, and linear regression analysis. Results: One year post-surgery,the CTV group exhibited a lower venous clinical severity score (VCSS) compared to the control group(M(IQR),3.0(4.3) vs.4.0(5.8),Z=-2.038,P=0.040).Additionally, the chronic venous insufficiency patients' quality of life questionnaire (CIVIQ-20) scores were significantly higher in the CTV group than in the control group (89.0(8.0) vs.82.5(17.0), Z=-2.627, P=0.010).Patients in the CTV group also experienced a shorter ulcer healing time compared to the control group (4.0(4.0) weeks vs.12.0(7.0) weeks, Z=-3.217,P<0.01).Both groups showed no clinically symptomatic recurrent varicose veins or ulcers.However, they exhibited ultrasound-detectable varicose vein recurrence, with no statistically significant difference (χ2=0.453,P=0.500).The number of diseased vessels requiring management based on ultrasound supplemented by CTV was 16, while the number supplemented by ascending phlebography was 7,with a statistically significant difference (χ2=4.800,P=0.030).Linear regression analysis demonstrated that clinical-etiology-anatomy-pathology clinical grading and the preoperative imaging examination method exerted independent influences on VCSS and CIVIQ-20 during the one-year postoperative assessment. Conclusions: CTV-assisted ultrasound enables a direct and comprehensive evaluation and localization of diseased veins in patients with recurrent varicose veins.The utilization of lower extremity vein ultrasound combined with CTV-guided management of lower extremity vessels in minimally invasive treatment significantly improves patient prognosis, surpassing the assessment provided by ascending phlebography.

Abstract
As a member of the pattern recognition receptors (PRRs) involving in the innate immune system, Toll-like receptors (TLRs) can sense a wide range of microbial pathogens and combat infections by producing antimicrobial products, inflammatory cytokines, and chemokines. All TLRs, with the exception of TLR3, activate a signalling cascade via the myeloid differentiation primary response gene 88 (MyD88). Therefore, the activation of MyD88-dependent signalling pathway must be finely controlled. Herein, we identified that cyclin-dependent kinase 5 (CDK5) negatively regulated TLR-MyD88 signalling pathway by targeting MyD88. Overexpression of CDK5 reduced the production of interferons (IFNs), while a deficiency in CDK5 increased the expression of IFNs in response to vesicular stomatitis virus (VSV) infection. Mechanistically, CDK5 suppressed the formation of MyD88 homodimers, resulting in the attenuated production of IFNs induced by VSV infection. Surprisingly, its kinase activity does not play a role in this process. Therefore, CDK5 can act as an internal regulator to prevent excessive production of IFNs by restricting TLR-MyD88-induced activation of antiviral innate immunity in A549 cells.

Abstract
Objective: To investigate how plasma exchange (PE) and double plasma molecular adsorption combined with half-volume plasma exchange (DPMAS + half-volume PE) affect the curative effect and short-term survival rate in liver failure. Methods: Data from 181 cases of liver failure caused by different etiologies from January 1, 2017 to September 31, 2020, were selected. Patients were divided into a PE treatment alone group and a DPMAS + half-dose PE treatment group. The laboratory indicators with different models of artificial liver before and after treatment and the survival rates of 7, 14, 28, and 90 days after discharge were observed in the two groups. Measurement data were analyzed by t-tests and rank sum tests. Categorical data were analyzed by χ (2) test. Results: Non-biological artificial liver therapy with different models improved the liver and coagulation function in the two groups of patients with liver failure (P < 0.05 in PTA% intra-group). The coagulation function was significantly improved in the PE treatment alone group compared with that in the DPMAS + half-dose PE group [PT after treatment: (20.15 ± 0.88) s in the PE treatment alone group, (23.43 ± 1.02) s, t = -2.44, P = 0.016 in the DPMAS+half-dose PE group; PTA: 44.72% ± 1.75% in the PE treatment alone group, 35.62% ± 2.25%, t = 3.215 P = 0.002 in the DPMAS + half-dose PE group]. Bilirubin levels were significantly decreased in the DPMAS+half-dose PE group compared to the PE treatment alone group [total bilirubin after treatment: (255.30 ± 15.64) μmol/L in the PE treatment alone group, (205.46 ± 9.03) μmol/L, t = 2.74, P = 0.07 in the DPMAS + half-dose PE group; direct bilirubin after treatment: (114.74 ± 7.11) μmol/L in the PE treatment alone group, (55.33 ± 3.18) μmol/L, t = 7.54, P < 0.001) in the DPMAS + half-dose PE group]. However, there was no significant effect on leukocytes and neutrophils after treatment with different models of artificial liver (P > 0.05) in the two groups, and platelets decreased after treatment, with no statistically significant difference between the groups (t = -0.15, P = 0.882). The inflammatory indexes of the two groups improved after treatment with different models of artificial liver (P < 0.05], and the 28 and 90 d survival rates were higher in the DPMAS+half-dose PE group than those of the PE treatment alone group (28 d: 60.3% vs. 75.0%, χ (2) = 4.315, P = 0.038; 90 d: 56.2% vs. 72.5%. χ (2) = 10.355 P < 0.001). DPMAS + half-dose PE group plasma saving was 1385 ml compared with PE treatment alone group (Z = -7.608, P < 0.05). Conclusion: Both DPMAS+half-dose PE and PE treatment alone have a certain curative effect on patients with liver failure. In DPMAS+half-dose PE, the 28-day survival rate is superior to PE treatment alone, and it saves plasma consumption and minimizes blood use in clinic.

Abstract
Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

Abstract
Relevant research in recent years has demonstrated that the atrial fibrillation occurrence rate is significantly higher in patients with cirrhosis. The most common indication for long-term anticoagulant therapy is chronic atrial fibrillation. The use of anticoagulant therapy greatly reduces the incidence rate of ischemic stroke. Patients with cirrhosis combined with atrial fibrillation have an elevated risk of bleeding and embolism during anticoagulant therapy due to cirrhotic coagulopathy. At the same time, the liver of such patients will go through varying levels of metabolism and elimination while consuming currently approved anticoagulant drugs, thereby increasing the complexity of anticoagulant therapy. This article summarizes the clinical studies on the risks and benefits of anticoagulant therapy in order to provide a reference for patients with cirrhosis combined with atrial fibrillation.

Abstract
Objective: To explore the application value of plasma proteomics in the diagnosis and pathogenesis of high altitude polycythemia (HAPC). Methods: Ten patients with HAPC in Qinghai Provincial People's Hospital from January 2020 to January 2021 were selected as the experimental group, including 4 males and 6 females, aged (46±4) years. Ten healthy controls at the same altitude in the same period were selected as the control group, including 5 males and 5 females, aged (44±4) years. The differential proteins were identified and quantified by high performance liquid chromatography-mass spectrometry (HPLC-MS), and the gene ontology (GO) functional enrichment analysis, the Kyoto Encyclopedia of Genes and Genomes (KEGG) functional enrichment analysis and interaction network analysis were conducted for the selected differential proteins. Results: A total of 117 differential proteins with quantitative values were screened from the experimental group and the control group, 45 significantly up-regulated proteins with quantitative values only in the experimental group, 40 significantly down-regulated proteins with quantitative values only in the control group, and 32 differentially expressed proteins with quantitative values in both experimental and control groups were detected. Compared with the control group, 11 of the 32 differentially expressed proteins in the experimental group were down-regulated and 21 were up-regulated. The results of GO functional enrichment analysis showed that the biological processes involved by differential proteins mainly included immune response, complement activation, activated protein cascade and coagulation system. The results of KEGG function enrichment analysis showed that the main biochemical metabolic pathways and signal transduction pathways involved by differential proteins were axon guidance, lysosomes, cell adhesion molecules, lipid and atherosclerosis, hematopoietic cell lineage and cholesterol metabolism. The abundant domains are mainly in immunoglobulin-like domain, EGF-like domain, fibronectin type Ⅲ superfamily, serine proteases, Sushi/SCR/CCP superfamily. The results of differential protein interaction analysis showed that the interaction score was>700, and the top 10 differential proteins with the largest number of nodes were MPO, RPS27A, ARG1, GM2A, TIMP1, CRP, FABP5, HBB, S100A7 and RHOA, respectively. Conclusion: Plasma proteomics analysis technique is helpful to identify the related protein markers in the development of HAPC, and provide reference for the diagnosis and pathogenesis of HAPC.

Abstract
Objective: To construct a prediction model of pathologic complete response (pCR) in locally advanced rectal cancer patients who received programmed cell death protein-1 (PD-1) antibody and total neoadjuvant chemoradiotherapy by using radiomics based on MR imaging data and to investigate its predictive value. Methods: A clinical diagnostic test study was carried out. Clinicopathalogical and radiological data of 38 patients with middle-low rectal cancer who received PD-1 antibody combined with total neoadjuvant chemoradiotherapy and underwent TME surgery from January 2019 to September 2021 in our hospital were retrospectively collected. Among 38 patients, 23 were males and 15 were females with a median age of 68 (47-79) years and 13 (34.2%) a chieved pCR. These 38 patients were stratified and randomly divided into the training group (n=26) and test group (n=12) for modeling. All the patients underwent rectal MRI before treatment. The clinical, imaging and radiomics features of all the patients were collected, and the clinical feature model and radiomics model were constructed. The receiver operating characteristic (ROC) curves of each model were drawn, and the constructed model was evaluated through the area under the curve (AUC), accuracy, sensitivity, specificity, positive predictive value and negative predictive value. Results: There were no significant differences in age, gender, primary location of tumor and postoperative pathology between the two groups (all P>0.05). Forty-one features were extracted from region of interest in each modality, including 9 first-order features, 24 gray level co-occurrence matrix features and 8 shape features. From 38 patients, 41 features were extracted from each imaging modality of baseline and preoperative DWI and T2WI images, totally 164 features. Only 4 features were preserved after correlation analysis between each pair of features and t-test between pCR and non-pCR subjects. After LASSO cross validation, only the first-order skewness of the baseline DWI image before treatment and the volume in the baseline T2WI image before treatment were retained. The area under the curve, sensitivity, specificity, positive and negative predictive values of the prediction model established by applying these two features in the training group and the test group were 0.856 and 0.844, 77.8% and 100.0%, 88.2% and 75.0%, 77.8% and 66.7%, 88.2% and 100.0%, respectively. The decision curve analysis of the radiomics model showed that the strategy of this model in predicting pCR was better than that in treating all the patients as pCR and that in treating all the patients as non-pCR. Conclusion: The pCR prediction model for rectal cancer patients receiving PD-1 antibody combined with total neoadjuvant radiochemotherapy based on MRI radiomics has the potential to be used in clinical screening or rectal cancer patients who can be spared from radical surgery.

Abstract
Objective: To study the clinical outcomes and feasibility of immediate implantation after flap surgery and minimally invasive extraction in the maxillary molar area and to provide a reference for it. Methods: Forty-one patients (41 molars in total) with maxillary molars that could not be preserved, treated from June 2018 to June 2020 at the Department of Oral and Maxillofacial Surgery at the Affiliated Hospital of Qingdao University, were selected. There are 24 males and 17 females with the age of (49.7±1.8) years (range 18-66 years). Pre-operative cone-beam CT (CBCT) was taken for measurement and analysis. After flap surgery and minimally invasive tooth extraction, the inflammatory granulation tissues attached to the soft and hard tissues were completely scraped and clipped, followed by the preparation of the implants in the correct three-dimensional position. Torque value and implant stability quotient (ISQ) were recorded after implant placement and with non-submerged healing. CBCT examination was taken 6 months after surgery and ISQ value was checked before crown restoration. CBCT examination was also taken 1 year after the permanent restoration. The survival rate of 6 months after surgery, the success rate of 1 year after permanent restoration, and the size of jump gaps immediately after surgery, 6 months after surgery, 1 year after permanent restoration respectively, were performed. The ISQ values were compared immediately and 6 months after surgery. Results: A total of 41 implants were placed in 41 patients. Six months after surgery, the survival rate was 100% (41/41). Twelve months after permanent restoration, the success rate of the implant restoration was 100% (41/41). The torque value after implant implantation was (42.77±0.79) N·cm. The buccal and palatal jump gaps were (3.15±0.16) mm and (2.86±0.18) mm immediately after surgery, respectively. The mesial and distal jump gaps were (2.94±0.19) mm and (3.77±0.21) mm, respectively. CBCT showed that no jump gap around the implants at 6 months after surgery and 1 year after permanent restoration. The ISQ values at immediately and 6 months after surgery were (74.78±0.59) and (80.20±0.49) respectively, and the difference was statistically significant (t=-9.03, P<0.001). Conclusions: Immediate dental implantation in the correct three-dimensional position could achieve good osseointegration by means of flap surgery, minimally invasive extraction and thorough removal of inflammatory tissue on the surface of soft and hard tissues. The clinical outcomes were satisfactory.

Abstract
Background Limited information about Toxoplasma gondii infection in pet cats and their owners is available in China. Methods In this study, blood samples were randomly collected from 306 pet cats and 397 corresponding pet owners in Jilin province, northeastern China. Sera from the pet cats and the pet owners were tested for anti-T. gondii antibodies using an modified agglutination test (MAT) and an enzyme-linked immunosorbent assay (ELISA), respectively. Moreover, the risk factors for T. gondii infection in pet cats and corresponding pet owners were explored. Result In total, 62 sera out of 306 examined pet cats (20.3%) and 18.1% (72/397) pet cat owners were seropositive for T. gondii, respectively. The results of statistical analysis showed that both pet cats and their owners from rural area had significantly higher T. gondii seroprevalence than those from urban area (p < 0.001). Moreover, owners of pet cas who have the knowledge of zoonotic protozoan diseases had a significantly lower T. gondii seroprevalence than those without the knowledge of zoonotic protozoan diseases (p < 0.001). Conclusions The present results revealed that the seroprevalence of T. gondii infection are widespread in pet cats and their owners in Jilin province, northeastern China. Residence area and understanding knowledge of zoonotic protozoan diseases are considered to be raleted to the T. gondii infection. Hence, it is necessary to highlight the dangers and protection methods of zoonotic protozoan diseases caused by pet cats, especially in rural area.

Abstract
Objective: To explore the difference of high-risk factors between early-onset and late-onset pre-eclampsia, and to further understand high-risk factors of pre-eclampsia. Methods: Clinical data of pre-eclampsia pregnant women in 160 medical institutions in China in 2018 were retrospectively analyzed, including 8 031 cases of early-onset pre-eclampsia and 12 969 cases of late-onset pre-eclampsia. The proportion of high-risk factors, different body mass index (BMI) and age stratification between early-onset group and late-onset group were compared. Results: (1) Univariate analysis of high-risk factors: the proportions of high-risk factors in early-onset group and late-onset group were compared, and the differences were statistically significant (all P<0.05). Among them, the proportions of primipara and multiple pregnancy in early-onset group were lower than those in late-onset group, while the proportions of pregnant women with advanced age, irregular antenatal examination, obesity, family history of hypertension, pre-eclampsia, diabetes, kidney diseases, immune system diseases and assisted reproductive technology were higher than those in late-onset group. (2) Hierarchical analysis of BMI: the proportion of pregnant women with BMI≥24 kg/m2 in early-onset group [48.2% (2 828/5 872) vs 45.5% (4 177/9 181), respectively; P=0.001] and the proportion of pregnant women with BMI ≥28 kg/m2 in early-onset group [19.5% (1 143/5 872) vs 18.0% (1 656/9 181), respectively; P=0.028] were significantly higher than those in late-onset group. (3) Age stratification analysis: the proportion of pregnant women aged 35-39 years in the early-onset group [21.8% (1 748/8 023) vs 17.5% (2 110/12 068), respectively; P<0.01], the proportion of pregnant women 40-44 years old [6.8% (544/8 023) vs 5.4% (648/12 068), respectively; P<0.01], and the proportion of pregnant women ≥45 years old [0.7% (58/8 023) vs 0.5% (57/12 068), respectively; P=0.021] were significantly higher than those in the late-onset group. (4) Multivariate analysis: advanced age (≥35 years old), multiple pregnancy, irregular antenatal examination or transfer from other hospitals, family history of hypertension (including paternal, maternal and parental lines), previous history of pre-eclampsia, kidney diseases, immune system diseases (systemic lupus erythematosus, antiphospholipid antibody syndrome) and assisted reproductive technology pregnancy were the risk factors affecting the severity of pre-eclampsia (all P<0.05). Conclusion: Pregnant women with high risk factors such as age ≥35 years old, BMI ≥24 kg/m2 before pregnancy, family history of hypertension, history of pre-eclampsia, chronic kidney diseases, immune diseases (mainly including systemic lupus erythematosus and antiphospholipid syndrome) and assisted reproductive technology are more likely to have early-onset pre-eclampsia.

Abstract
The complete mitochondrial genome of the perlodid stonefly, Filchneria songi Chen, 2019 was sequenced and analyzed. This double strand, circular molecule is 16,028 bp in length with an A + T content of 70.1%, and contains 13 PCGs, 22 tRNA genes, and two rRNA genes. A 1099-bp long control region was detected, with a high A + T content of 81.9%. Gene arrangement was conserved in the mitogenome of F. songi. Most PCGs use standard start codons and ended with complete stop codons. The phylogenetic analysis supported that F. songi was closely related with species of Perlodes Banks, 1903.

Abstract
Objective: To analyze the epidemiological characteristics of close contacts of COVID-19 cases and infection-related risk factors in Beijing and provide evidences for COVID-19 prevention and control. Methods: A total of 20 681 close contacts of COVID-19 cases, who had exposures during January 6, 2020 to February 15, 2021, were traced in Beijing. The information about their demographic characteristics, exposure history, and quarantine outcomes were collected and analyzed with descriptive statistics. The logistic regression analysis was used to identify the risk factors for COVID-19. Results: The infection rate SARS-CoV-2 in close contacts was 2.16% (447/20 681). The age M(P25, P75) was 35 (27, 49) years. The majority of the close contacts were aged 20-59 years, accounting for 81.77% (16 912/20 681). Centralized isolation was the major type of medical observation, accounting for 82.15% (16 989/20 681). Among the exposure types, working and studying in the same room (16.06%, 3 322/20 681), sharing same transport vehicle (12.88%, 2 664/20 681), performing diagnosis and treatment nursing (7.80%,1 612/20 681), and living together (7.23%,1 495/20 681), accounting for 43.96% (9 093/20 681). The index cases included staff (19.34%, 3 999/20 681), the unemployed (17.34%, 3 586/20 681), people engaged in business service (13.85%, 2 864/20 681), people engaged in food service (10.77%, 2 228/20 681), their close contacts accounted for 61.30% (12 677/20 681). Multivariate logistic regression analysis showed that compared with other types of exposure, the risk factors for infection were having meal together (OR=3.96, 95%CI: 2.30-6.83) and living together (OR=6.41, 95%CI:4.48-9.17); Compared with the other occupations, the index case being engaged in food service (OR=3.06, 95%CI:1.29-7.25) and teacher (OR=4.94, 95%CI:1.43-17.08) were risk factors for the infection. Conclusions: The main environmental exposure types of SARS-CoV-2 infection in close contacts were having meal together and living together. Contact with the index case being engaged in food service and teacher increased the risk for COVID-19. Comprehensive prevention and control measures such as centralized isolation and vaccination should be continued.

Abstract
With further climate change still expected, it is predicted to increase the frequency with plants will be water stressed, which subsequently influences phytophagous insects, particularly Lepidoptera with limited mobility of larvae. Previous studies have indicated that oviposition preference and offspring performance of Lepidoptera insects are sensitive to drought separately. However, the integration of their two properties is not always seen. Here, we evaluated changes in oviposition selection and offspring fitness of a Lepidoptera insect under three water-stressed treatments using a model agroecosystem consisting of maize Zea mays, and Asian corn borer Ostrinia furnacalis. Results found that female O. furnacalis preferred to laying their eggs on well-watered maize, and then their offspring tended to survive better, attained bigger larvae mass, and developed more pupae and adults on the preferred maize. Oviposition selection of O. furnacalis positively correlated with height and leaf traits of maize, and offspring fitness positively related with water content and phytochemical traits of hosts. Overall, these results suggest that oviposition choice performed by O. furnacalis reflects the maximization of offspring fitness, supporting preference-performance hypothesis. This finding further highlights that the importance of simultaneous evaluation of performance and performance for water driving forces should be involved, in order to accurately predict population size of O. furnacalis under altered precipitation pattern.

Abstract
Objective: To investigate the prevention and treatment status of venous thromboembolism (VTE) of pregnant women in general hospitals and specialized hospitals in China. Methods: This study was a cross-sectional survey about VTE prevention and treatment in 112 hospitals across China from January 1st to December 31st, 2019, including general information, resource accessibility, hospital system and strategy. According to the characteristics, the hospitals were divided into general hospital group (70 hospitals) and specialized hospital group (42 hospitals). The basic information, VTE diagnosis and treatment resources, prevention systems and the preference of the VTE risk assessment form of the two groups were compared. Logistic regression was used to analyze the proportion of VTE incidence and related factors in the two groups of hospitals. Results: (1) The median annual delivery volume of the general hospital group was significantly lower than that of the specialized hospital group (3 428 vs 9 969 cases, P<0.01), the diagnostic accessibility of CT pulmonary angiography (CTPA) was significantly higher than that of the specialized hospital [92.9% (65/70) vs 59.5% (25/42), P<0.01], and the proportion of obstetric VTE risk assessment was significantly higher than that of the specialized hospital group [85.7% (60/70) vs 66.7% (28/42), P=0.017]. (2) Among the 88 hospitals using the VTE risk assessment sheet, the utilization rate of the evaluation sheet recommended by the obstetric VTE guideline in specialized hospitals (78.6%, 22/28) was higher than that of general hospitals (48.3%, 29/60), and the difference was statistically significant (P=0.007). (3) The proportion of VTE incidence in general hospital group was 0.126% (360/286 517), and the proportion of VTE incidence in specialized hospital group was 0.032% (154/484 111). Logistic regression analysis showed that the OR value of the specialized hospital group was 0.253 (95%CI: 0.209-0.305) and the difference was statistically significant (P<0.01) compared with the general hospital group. After adjusting the hospital level, B-ultrasonography and CTPA accessibility, whether to establish a risk assessment and obstetric VTE system, the proportion of VTE incidence in specialized hospitals was still lower than that in general hospitals (OR=0.307, 95%CI: 0.251-0.376, P<0.01). Conclusions: General hospitals have higher access to resources for diagnosing VTE than specialized hospitals, and the VTE evaluation system is better implemented. The utilization rate of the obstetric VTE guidelines in specialized hospitals is higher than that of general hospitals.

Abstract
Objective: To observe the application of three different kinds of endotracheal intubation in the combined thoracoscopic and laparoscopic esophagectomy. Methods: one hundred and eighty patients undergoing combined thoracoscopic and laparoscopic esophagectomy under general anesthesia from the Affiliated Cancer Hospital of Zhengzhou University from February to September 2019 were randomly divided into three groups which include: double-lumen endotracheal intubation group (group S,n=60),single-lumen endotracheal intubation group (group D,n=60) and Coopdech occlusion of bronchial catheter combined with a single-lumen endotracheal intubation group (group C,n=60). The arterial blood samples were collected immediately after endotracheal intubation (T0), 30 min after artificial pneumothorax (single lung ventilation) (T1), 30 min after artificial pneumothorax (double lung ventilation) (T2), and 30 min after extubation (T3) to detect arterial blood gas. Patients' heart rate (HR), blood oxygen partial pressure (PaO2), blood carbon dioxide partial pressure (PaCO2) and airway pressure(Paw) were recorded at T0-T3.Completion time of endotracheal intubation, carbon dioxide intrathoracic inflation pressure, degree of lung collapse and incidence of postoperative 3-day pneumonia in three groups were recorded. The bronchoalveolar lavage fluid (BALF) of patients at T0, T2 and the end of the operation (T4) were collected to detect the levels of tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6) and interleukin-8 (IL-8) in BALF by enzyme-linked immunosorbent assay (ELISA). Results: A total of 14 patients were excluded during the operation, of which 9 cases lasted longer than 6 hours, 3 cases had arrhythmia during the operation and 2 cases lasted less than 1 hour. Finally, 56 cases in group S, 54 cases in group D and 56 cases in group C completed the experiment. The satisfaction rates of lung collapse in group S, group D and group C were 85.7% (48/56), 100.0% (54/54), 89.2% (50/56), respectively, with no statistically significant difference (χ²=1.308, P>0.05). The intrathoracic inflation pressure of carbon dioxide in group D was (10.2±2.2) mmHg (1 mmHg=0.133 kPa), which was higher than (5.1±3.4) mmHg in group S and (5.6±3.1) mmHg in group C, the difference was statistically significant (F=-9.303, P<0.05). The incidence of postoperative 3-day pneumonia in group D was 14.8%, which was lower than 39.3% in group S and 17.8% in group C, the difference was statistically significant (χ²=8.300, P<0.05). At T4, the value of TNF-α in group D was (122.4±4.4) ng/L, which was lower than that in group S and group C, (257.9±6.3) and (185.8±5.6) ng/L, with statistically significant difference (F=69.020, P<0.05). At T4, the value of IL-6 in group D was (175.4±4.9) ng/L, which was lower than that of patients in group S and group C, (289.6±6.8) and (226.2±4.4) ng/L, with statistically significant difference (F=59.750, P<0.05). At T4, the value of IL-8 in group D was (303.1±7.2) ng/L, which was lower than in group S and group C, (595.4±22.1) and (436.8±10.9) ng/L, with statistically significant difference (F=55.359, P<0.05). Conclusion: All the three endotracheal intubations can produce satisfactory ventilation effect in the combined thoracoscopic and laparoscopic esophagectomy, however, single-lumen endotracheal intubation has less effect on lung injury.

Abstract
Objective: To investigate the role of 1, 25-dihydroxyvitamin D3 [1.25(OH) (2)D(3)] in liver lipid metabolism so as to provide the clues for elucidating the mechanism of non-alcoholic fatty liver. Methods: 26 SD rats were randomly divided into control group (methionine-choline-sufficient diet, MCS), model group (methionine-choline-deficiency diet, MCD) and intervention group [MCD+1.25(OH) (2)D(3)]. The intervention, control, and model group was given 3 ng/100 g 1.25(OH) (2)D(3) peanut oil solution per day by gavage according to body mass. After 4 weeks the experiment was ended up, and the blood was collected from the inferior vena cava to detect alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The liver tissue was collected to observe the liver morphological and pathological changes (oil red O and HE staining). The changes in the level of liver total triglyceride (TG) content and liver lipid metabolism-related genes [fatty acid transfer protein (FAT/CD36), acetyl-coenzyme A carboxylase (ACC1)] mRNA and protein were detected. One-way analysis of variance was used to compare the means between groups. Results: Oil red O staining and HE staining showed that lipid droplet-vacuoles were significantly increased in the liver tissue of the model group than that of the intervention group. The liver TG content (2.23 ± 0.98) μmol/g of the intervention group was significantly lower than that of the model group (3.53 ± 1.06) μmol/g (F = 5.930, P = 0.035). The ALT content of the intervention group (35.99±9.54) U/L was significantly lower than that of the model group (57.65 ± 19.42) U/L (F = 13.790, P = 0.034). The AST content of the intervention group (16.9 ± 3.73) U/L was significantly lower than that of the model group (27.81 ± 13.31) U/L (F = 3.084, P = 0.046). The relative expression levels of mRNA and protein (mRNA: 1.21 ± 0.61, protein: 1.54 ± 0.75) of FAT/CD36 in the intervention group were significantly lower than those of the model group (mRNA: 2.31 ± 0.81, protein: 2.83 ± 1.42) (mRNA: F = 8.370, P = 0.001, protein: F = 7.212, P = 0.043). The relative expression level of mRNA and protein of ACC1 (mRNA: 0.89 ± 0.54, protein: 0.28 ± 0.11) were also significantly lower than those in model group (mRNA: 1.39 ± 0.19, protein: 0.47 ± 0.24) (mRNA: F = 3.948, P = 0.036, protein: F = 10.933, P = 0.048). Conclusion: 1.25(OH) (2)D(3) can reduce liver fat deposition in rats fed with MCD by inhibiting the expression of fat / CD36 and ACC1.

Abstract
OBJECTIVE To compare the clinical therapeutic effect on painful diabetic peripheral neuropathy (PDPN) between dragon-tiger fighting needling and pregabalin capsules. METHODS A total of 60 patients with PDPN were randomized into an observation group and a control group, 30 cases in each one. On the base of treatment with routine anti-hyperglycaemic measures and nutritional neurotherapy, the dragon-tiger fighting needling was exerted at Sanyinjiao (SP 6), Zusanli (ST 36), Yinlingquan (SP 9) and Xuehai (SP 10) in the observation group, once daily. Pregabalin capsules were prescribed for oral administration in the control group, 75 mg, twice a day. The treatment for 2 weeks was as one course and 2 courses of treatment were required in total. The score of visual analogue scale (VAS), the score of MOS item short form health survey (SF-36) and nerve conduction velocity before and after treatment were compared between the two groups. The clinical therapeutic effect was evaluated in the two groups. RESULTS After treatment, VAS score was reduced as compared with before treatment in the two groups (P<0.05). The reducing range of VAS score in the observation group was larger than the control group (P<0.05). After treatment, the sensory nerve conduction velocity (SNCV) and motor nerve conduction velocity (MNCV) of median nerve and posterior tibial nerve were all improved as compared with before treatment in the two groups (P<0.05). SNCV and MNCV in the observation group were higher than the control group (P<0.05). After treatment, the score of each item in SF-36 was increased as compared with before treatment in the two groups (P<0.05) and the score of each item in SF-36 in the observation group was higher than the control group (P<0.05). The total effective rate was 86.7% (26/30) in the observation group, better than 60.0% (18/30) in the control group (P<0.05). CONCLUSION The dragon-tiger fighting needling therapy relieves painful symptoms, improves the quality of life and increases nerve conduction velocity in the patients with diabetic peripheral neuropathy, and the therapeutic effect is better than oral administration of pregabalin capsules.

Abstract
Alcohol use-associated disorders are highly comorbid with anxiety disorders; however, their mechanism remains unknown. The amygdala plays a central role in anxiety. We recently found that 7,8-dihydroxyflavone (7,8-DHF) significantly reduces withdrawal symptoms in a rat model of chronic intermittent alcohol (ethanol) exposure. This study aimed to determine the role of 7,8-DHF in regulating anxiety induced by chronic alcohol exposure and its associated underlying mechanism. Male C57BL/6J mice were exposed to chronic intermittent alcohol for 3 weeks followed by alcohol withdrawal for 12 h with or without 7,8-DHF administered intraperitoneally. All mice were tested using an open field test and elevated plus maze to assess anxiety-like behaviors. Synaptic activity and intrinsic excitability in basal and lateral amygdala (BLA) neurons were assessed using electrophysiological recordings. 7,8-DHF alleviated alcohol-induced anxiety-like behavior and attenuated alcohol-induced enhancement of activities in BLA pyramidal neurons. Furthermore, 7,8-DHF prevented alcohol withdrawal-evoked augmentation of glutamatergic transmission in the amygdala and had no effect on GABAergic transmission in the amygdala, as demonstrated by unaltered frequency and amplitude of spontaneous inhibitory postsynaptic currents. Microinjection of K252a, a tropomyosin-related kinase B (TrkB) antagonist, into the BLA blocked the effects of 7,8-DHF on anxiety-like behavior and neuronal activity in the BLA. Our findings suggest that 7,8-DHF alleviates alcohol-induced anxiety-like behavior induced by chronic alcohol exposure through regulation of glutamate transmission involving TrKB in the BLA.

Abstract
Objective: To evaluate the operability and clinical application effects of femtosecond laser-assisted cataract surgery systems of LenSx and LenSAR. Methods: This was a randomized controlled study. A total of 86 patients (90 eyes) who underwent femtosecond laser-assisted cataract surgery in Wuhan Aier Eye Hospital from April 2018 to November 2018 were enrolled and divided into two groups randomly, including 44 patients (45 eyes) in the LenSx group and 42 patients (45 eyes) in the LenSAR group. During the operation, the following observation indexes were obtained. Operational indicators included the number of docking attempts, anterior capsulotomy time, nucleus pre-treatment time, total femtosecond laser emission time, and total vacuum suction duration. Clinical outcome indicators included changes in the patient's intraocular pressure during femtosecond laser surgery, the rate of subconjunctival hemorrhage, capsulotomy integrity (yes/no), roundness and centricity of the anterior capsule opening (yes/no), the rate of anterior capsule opening tear, and the rate of posterior capsule rupture. The t-test, rank-sum test or chi-square test were used for statistical analysis. Results: There were no significant differences between groups in the age and the lens density (both P>0.05). The number of docking attempts in the LenSx group was 1 (1 to 4) and in the LenSAR group was 1 (1 to 2); there was statistically significant difference (Z =-2.23, P<0.05). The difference in the anterior capsulotomy time between the two groups was statistically significant [13.00 (10.00 to 22.00) s compared with 3.00 (1.00 to 3.00) s, Z=-8.71, P<0.05]. The femtosecond laser pre-nucleation time and total femtosecond laser emission time of the LenSx group were (16.67±3.36) s and (30.49±3.53) s, and those of the LenSAR group were (12.38±4.36) s and (15.36±4.29) s, respectively; the differences between the two groups were statistically significant (t=-5.23, -18.26; both P<0.05). The total vacuum suction duration in the LenSx group was (97.23±19.96) s, shorter than that in the LenSAR group [(123.76±16.81) s] (t=6.82, P<0.05). The intraocular pressure after femtosecond laser surgery in both groups was higher than that before surgery. The increase of intraocular pressure in the LenSAR group was (5.64±5.42) mmHg (1 mmHg=0.133 kPa), higher than that in the LenSx group [(2.99±4.66) mmHg] (t=-2.49, P<0.05). The rate of subconjunctival hemorrhage in the LenSx group was 33.3% (15/45), while it was 8.9% (4/45) in the LenSAR group; the difference between the two groups was statistically significant (χ²=6.67, P<0.05). There were no significant differences between groups in capsulotomy integrity, roundness and centricity of the anterior capsule opening, the rate of anterior capsule opening tear, and the rate of posterior capsule rupture (all P>0.05). Conclusion: The docking process of the LenSAR system is convenient, and there is less subconjunctival hemorrhage; the total vacuum suction duration of LenSx is short, and the increase of intraocular pressure is low.

Abstract
Objective: To establish a quantitative three-dimensional method based on intraoral scan to evaluate the changes of soft tissue, and to evaluate the changes of supracrestal gingival thickness (SGT) in skeletal class Ⅲ patients induced by periodontal regenerative and corticotomy surgery (PRCS). Methods: Twenty-two systematically and periodontally healthy skeletal class Ⅲ patients (4 males and 18 females, aged between 19 and 35 years), who were in need of combined orthodontic-orthognathic treatment and referred to the Department of Periodontology from the Department of Orthodontics and the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from January, 2018 to March, 2019, were collected in the study. The teeth involved were 112 anterior teeth (46 maxillary anterior teeth and 66 mandibular anterior teeth). PRCS in anterior tooth area was conducted before orthodontic decompensation. Probing depth (PD), bleeding index (BI) and keratinized gingiva width (KGW) were recorded before surgery and 6 months post-surgery. The intraoral digital impressions of maxillary and mandibular anterior teeth were obtained by 3-shape intraoral scanner before surgery and 6 months after surgery. The Standard Tessellation Language (STL) files were processed using Geomagic qualify 12.2 software to establish the soft tissue morphological measurement model, and to quantitatively analyze the changes of gingival thickness situated 1 to 2 mm apical to the free gingival margin on the median sagittal measurement plane. Results: Probing depth and bleeding index had no significant difference before and 6 months after operation (P>0.05). KGW in 6-month post-operation group [(5.18±2.32) mm] was significantly higher than that in pre-operation group [(4.22±1.43) mm] (P<0.05). Supracrestal gingival thickness situated 1 to 2 mm apical to the free gingival margin also significantly increased 6 months after surgery (P<0.05). The changes of gingival thickness situated 1 to 2 mm apical to the free gingival margin in the upper anterior area were (0.68±0.56) and (1.00±0.69) mm, respectively. The changes in the lower anterior area were (0.38±0.42) and (0.58±0.45) mm, respectively. The gingival changes of the upper anterior teeth were also significantly higher than those of the lower anterior teeth (P<0.01). Conclusions: The described quantitative measurement based on intraoral scan could be an effective method for quantitative evaluation of the changes of soft tissue. PRCS could safely increase the supracrestal gingival thickness as well as KGW in skeletal class Ⅲ patients who were in need of combined orthodontic-orthognathic treatment.

Abstract
The increase of blood pressure accelerates endothelial progenitor cells (EPCs) senescence, hence a significant reduction in the number of EPCs is common in patients with hypertension. Autophagy is a defense and stress regulation mechanism to assist cell homeostasis and organelle renewal. A growing number of studies have found that autophagy has a positive role in repairing vascular injury, but the potential mechanism between autophagy and senescence of EPCs induced by hypertension has rarely been studied. Therefore, in this study, we aim to explore the relationship between senescence and autophagy, and investigate the protective effect of rhynchophylline (Rhy) on EPCs. In angiotensin II (Ang II)-treated EPCs, enhancing autophagy through rapamycin mitigated Ang II-induced cell senescence, on the contrary, 3-methyladenine aggravated the senescence by weakening autophagy. Similarly, Rhy attenuated senescence and improved cellular function by rescuing the impaired autophagy in Ang II-treated EPCs. Furthermore, we found that Rhy promoted autophagy by activating AMP-activated protein kinase (AMPK) signaling pathway. Our results show that enhanced autophagy attenuates EPCs senescence and Rhy rescues autophagy impairment to protect EPCs against Ang II injury.

Abstract
OBJECTIVE To understand the prevalence and risk factors of Blastocystis hominis infection in inpatients in Jiangjin District, Chongqing City. METHODS A cross-sectional study was conducted in a community hospital in Jiangjin District, Chongqing City, and the inpatients were surveyed by questionnaires. After obtaining the informed consent from the inpatients or legal guardians, the stool and blood samples were collected and examined by microscopy and PCR from April 17 to May 1, 2018. The univariate analysis and logistic regression analysis were used to analyze the risk factors of the B. hominis infection. RESULTS A total of 198 hospitalized patients were investigated, and the infection rate of B. hominis was 10.61% (21/198), and the infection rate of the females (12.10%) was higher than that of the males (8.11%), but the difference was not statistically significant. The highest rate of infection was 19.23% in the age group of 10 to 20 years, followed by 17.74% in the age group of 60 years and above, and the lowest rate was 2.38% in the age group of 20 to 40 years. The difference in infection rates of B. hominis among the different age groups was statistically significant (P < 0.05). The infection rate of B. hominis in the people who used dry pail latrines was 33.30%, which was higher than that of the people who used water flush toilets (9.10%) (P < 0.05). The genotypes of B. hominis were ST1, ST3, ST6 and ST7, and ST6 and ST3 being the most predominant genotypes which accounted for 47.62% (10/21) and 38.10% (8/21) respectively, and among the infected males, the genotypes were only ST3 and ST6. The multiple logistic regression analysis showed that among the factors affecting B. hominis infection, only keeping pets was a risk factor [OR = 3.798, 95% CI (1.245, 11.581), P < 0.05]. CONCLUSIONS A high prevalence of B. hominis infection is found in the inpatients in Jiangjin District, Chongqing City, the predominant genotypes are ST6 and ST3, and keeping pets may be one of the main risk factors.

Abstract
PURPOSE To systematically review studies investigating health-related quality-of-life (HrQoL) in patients with premature ovarian insufficiency (POI), to examine questionnaires used and to conduct a meta-analysis of control studies with normal ovarian function. METHODS Data sources: PubMed, Embase, Web of science, CNKI, and CQVIP, searched from inception until June 2018. The search strategy was a combination of medical (e.g. POI), subjective (e.g. well-being) and methodological (e.g. questionnaires) keywords. PRISMA guidelines were used to assess outcome data quality/validity by one reviewer, verified by a second reviewer. Risk of bias within studies was evaluated. A meta-analysis compared HrQoL in patients and non-patients. Due to measurement differences in the studies, the effect size was calculated as standard mean difference. RESULTS We identified 6869 HrQoL studies. Nineteen geographically diverse studies met inclusion criteria, dated from 2006, using 23 questionnaires. The meta-analysis included six studies with 645 POI participants (age 33.3 ± 5.47) and 492 normal-ovarian control subjects (age 32.87 ± 5.61). Medium effect sizes were found for lower overall HrQoL (pooled SMD = - 0.73, 95% CI - 0.94, - 0.51; I2 = 54%) and physical function (pooled SMD = - 0.54, 95% CI - 0.69, - 0.39; I2 = 55%). Heterogeneity was investigated. Effect sizes varied for sexual function depending on the measure (SMD = - 0.27 to - 0.74), overall HrQoL (SF-36) had the largest effect size (- 0.93) in one study. The effect sizes for psychological and social HrQoL were small. CONCLUSION POI is associated with low-to-medium effect size on HrQoL compared to normal ovarian controls. The greatest effects are found in general HrQoL and most sexual function areas. Condition-specific questionnaires and RCTs are recommended for further investigation.

Abstract
Understanding soil physical properties is essential for soil quality management and sustainable land use. With the growing accumulation of microplastics in soils, a better understanding of the impact of microplastics on soil physical properties is crucial to conserve and manage soil quality. This study explored the effects of polyester microfiber (PMF) concentrations (0, 0.1% and 0.3%) on bulk density, porosity, aggregation and hydraulic conductivity of a clayey soil from a field experiment (1 year) and a pot experiment (6 wet-dry cycles). Polyester microfibers significantly increased the volume of >30 μm pores and reduced the volume of <30 μm pores compared to the control treatment. However, there were no detectable changes in the soil bulk density and saturated hydraulic conductivity between the PMF treatments and the control treatment. Interestingly, we observed that polyester microfibers significantly increased the contents of water stable large macroaggregates (>2 mm) in the 0.3% PMF (44%) and 0.1% PMF (39%) treatments compared to the control treatment (31%) in the pot experiment, but this was not true in the field experiment. The efficient interaction between polyester microfibers and fine soil particles and the frequent wet-dry cycles enhanced the formation and stability of macro-aggregates induced by polyester microfibers in the pot experiment. Overall, our results provide valuable evidence for microplastic influences on soil physical properties. Because microplastics are long-term anthropogenic contaminants, it is necessary to further study the impacts of microplastics on soil quality for terrestrial ecosystem sustainability.

Abstract
Currently, the main sample pretreatment methods for forensic toxic analysis are liquid-liquid extraction (LLE) and solid-phase extraction (SPE). As a simple, convenient, and low-cost LLE method, dispersion liquid-liquid microextraction (DLLME) has high enrichment factor and good extraction efficiency, and therefore has attracted the attention of many researchers in the field of toxicology analysis in recent years. As a multi-functional microextraction method, DLLME has been widely used in the analysis of pesticides, sleeping sedatives, drugs and heavy metal poisons in forensic toxic analysis. Meanwhile, it can also be used in combination with such a variety of analytical instruments as gas chromatography-electron capture detectors (GC-ECD), high performance liquid chromatography-diode array detectors (HPLC-DAD). As a sample pretreatment method, DLLME has the advantages of simple operation, less use of organic solvent, reliable results and good reproducibility, thus can meet the requirements of modern court toxic analysis.

Abstract
Background A cross-talk between Toll-like receptor 4 (TLR4) and matrix metalloproteinase 9 (MMP9) plays a vital role in aortic pathophysiology. The objective of this study was to evaluate the interactions between TLR4 and MMP9 polymorphisms in the risk of aortic aneurysm (AA) and its subtypes. Methods KASP method was used to detect polymorphisms of TLR4 (rs11536889 and rs1927914) and MMP9 (rs17576) in 472 AA patients and 498 controls. According to location and size, AA patients were further classified into abdominal AA (AAA), thoracic AA (TAA), and large AA (>5.0 cm), small AA(≤5.0 cm), respectively. Results The significant interaction effect of TLR4rs1927914 with MMP9rs17576 polymorphisms was observed for the risk of TAA (Pinteraction = 0.038, OR = 6.186) and large AA (Pinteraction = 0.044, OR = 5.892). There were epistatic effects between TLR4rs1927914 and MMP9rs17576 polymorphisms on the risk of overall AA, AAA, TAA and large AA when they were present together. Moreover, the cumulative effects of the pairwise interaction TLR4rs1927914-MMP9rs17576 were associated with an increased risk of overall AA (Ptrend = 0.032) and AAA (Ptrend = 0.031). Conclusions The novel interaction between TLR4rs1927914 and MMP9rs17576 polymorphisms could increase the risk of AA disease or its subtypes by exerting epistatic and cumulative effects.

Abstract
Background Matrix metalloproteinase-9 (MMP9) has been reported to play a key role in the pathogenesis of aortic aneurysm. However, few studies have assessed serum MMP9 levels in both abdominal aortic aneurysm (AAA) and thoracic aortic aneurysm (TAA). In this study, we investigated the serum levels of MMP9 in aortic aneurysm to evaluate its predictive and diagnostic efficacy for AAA and TAA, and explored the association of MMP9 with circulating laboratory markers. Methods A total of 296 subjects were enrolled, including 105 AAA patients, 79 TAA patients and 112 healthy controls. The levels of serum MMP9 were detected by enzyme-linked immunosorbent assay (ELISA). Results Compared to control group, both AAA and TAA patients had higher serum MMP9 levels in the overall comparison and subgroup analysis based on subjects aged<65 years, either male or female, hypertension, non-diabetes and non-hyperlipidemia (all P<0.05). Moreover, MMP9 levels were significantly higher in TAA group than those in AAA group in the total comparison, and this discrepancy was also found in the non-diabetes, non-hyperlipidemia and aortic diameter ≥ 5.5 cm subgroup analysis. Serum MMP9 levels were influenced by age and hypertension. There was a positive association of serum MMP9 with CRP (r = 0.33, P < 0.001) and Hcy (r = 0.199, P = 0.033). Multiple logistic analyses showed that serum MMP9 was an independent risk factor for AAA and TAA. Based on receiver operating characteristic (ROC) analysis, the area under the curve (AUC) of MMP9 for predicting TAA was 0.83 with 70% sensitivity and 91% specificity, while the AUC of MMP9 to detect AAA was 0.69 and the sensitivity and specificity were 50% and 88%. Conclusions Serum MMP9 was closely related to the existence of aortic aneurysms and could be a valuable marker for the discrimination of aortic aneurysm, especially for TAA.

Abstract
Glioma is the most common sub-type of brain tumor. Due to the presence of stem-like cells, it is characterized by poor prognosis, aggressive ability and high post-surgical recurrence rates. Hence, there is critical need to identify molecular mechanisms of glioma stem-like cells. We found a novel lncRNA in the ZNF281 gene and named it lncRNA-ZNF281. We detected the expression of lncRNA-ZNF281 in glioma stem-like cells (U251s), the glioma cell line (U251) and also in normal brain tissue. The expression of lncRNA-ZNF281 was lower in glioma stem-like cells (U251s) and this indicates that lncRNA-ZNF281 can regulate the self-renewal capacity of glioma stem-like cells and stem cell marker expression. Most significantly, lncRNA-ZNF281 inhibits the invasion of glioma stem-like cells by regulating the expression of the NF-κB1 signaling pathway. Our data demonstrates that lncRNA-ZNF281 inhibits the self-renewing ability and invasion of GSCs in vitro and in vivo and can reduce tumorigenicity in the glioma stem-like cell (U251s). The underlying mechanisms may involve the regulation of stem cell markers (CD133, Nestin, OCT4 and Nanog) to reduce the self-renewal ability and regulate the NF-κB1 signaling pathway and inhibit U251s glioma stem-like cell invasion. These finding suggest that lncRNA-ZNF281 could be a successful new therapeutic target in glioma.

Abstract
Controlled and compacted TiAl3 coating was successfully fabricated on the network structured TiBw/Ti6Al4V composites by hot-dipping aluminum and subsequent interdiffusion treatment. The network structure of the composites was inherited to the TiAl3 coating, which effectively reduces the thermal stress and avoids the cracks appeared in the coating. Moreover, TiB reinforcements could pin the TiAl3 coating which can effectively improve the bonding strength between the coating and composite substrate. The cycle oxidation behavior of the network structured coating on 873 K, 973 K and 1073 K for 100 h were investigated. The results showed the coating can remarkably improve the high temperature oxidation resistance of the TiBw/Ti6Al4V composites. The network structure was also inherited to the Al2O3 oxide scale, which effectively decreases the tendency of cracking even spalling about the oxide scale. Certainly, no crack was observed in the coating after long-term oxidation due to the division effect of network structured coating and pinning effect of TiB reinforcements. Interfacial reaction between the coating and the composite substrate occurred and a bilayer structure of TiAl/TiAl2 formed next to the substrate after oxidation at 973 K and 1073 K. The anti-oxidation mechanism of the network structured coating was also discussed.

OBJECTIVE To evaluate the accuracy and reliability of detecting alveolar bone dehiscence and fenestration of maxillary anterior teeth of Angle class III by cone-beam computed tomography (CBCT). METHODS Eighteen Angle class III patients with 108 maxillary anterior teeth were included (3 males and 15 females) who accepted modified corticotomy in orthodontic therapy. The mean age was 23.6 years (18-30 years). The clinical detection of dehiscence and fenestration was done when modified corticotomy was performed by the same periodontist. The CBCT examination was conducted pre-operation and the detection of dehiscence and fenestration by CBCT was done by two periodontists. The data in modified corticotomy were used as the golden standard to calculate the parameters, such as sensitivity, specificity, positive and negative predictive values, Youden index (YI), positive and negative likelihood ratio. Kappa statistic was used to analyze the agreement between the clinical detection and the CBCT detection. RESULTS The incidence of dehiscence and fenestration was about 10.19% and 13.89% respectively, which mainly occurred on lateral incisors and canines. The median values of length and width of dehiscence were about 5 mm and 4 mm, and the median values of length and width of fenestration were 3 mm and 2 mm, respectively. Most fenestrations were detected on the middle third to the apical third of the root. For dehiscence, the agreement between clinical detection and CBCT detection was statistically significant (P<0.05). For fenestration, the agreement between clinical detection and CBCT detection was statistically significant (P<0.05). The values of sensitivity and specificity for detecting dehiscence were more than 0.7. The values of positive and negative predictive values for detecting dehiscence were 0.44 and 0.97. The values of sensitivity and specificity for detecting fenestration were 0.93 and 0.52. The values of positive and negative predictive values for detecting fenestration were 0.24 and 0.98. CONCLUSION For dehiscence, the agreement between clinical detection and CBCT detection was good. For fenestration, the agreement between clinical detection and CBCT detection was general. Detection of dehiscence and fenestration of maxillary anterior teeth of Angle class III by CBCT had limited diagnostic value in clinical practice with overestimation of dehiscence and fenestration incidence.

Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) have a high risk of developing colorectal neoplasia. AIM To investigate whether thiopurines can decrease the risk of developing colorectal neoplasia in patients with ulcerative colitis (UC) or Crohn's disease (CD). METHODS We conducted a meta-analysis of 24 observational studies involving 76,999 participants to evaluate the risks of developing colorectal neoplasia in IBD patients receiving thiopurine treatment. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) for the risks of colorectal neoplasia were calculated using a random-effects model. RESULTS The overall pooled estimate revealed a protective effect of thiopurine use on colorectal neoplasia in patients with IBD (OR = 0.63, 95% CI 0.46-0.86). The effect was significant in UC patients (OR = 0.67, 95% CI 0.45-0.98), but was not significant in CD patients (OR = 1.06, 95% CI 0.54-2.09). Thiopurines exposure significantly decreased the risk of colorectal cancer (CRC) (OR = 0.65, 95% CI 0.45-0.96) and advanced colorectal neoplasia (CRC and/or high-grade dysplasia) (OR = 0.62, 95% CI 0.44-0.89), but did not decrease the risk of dysplasia alone (OR = 0.90, 95% CI 0.37-2.21). Tendencies towards the protective effect of thiopurines were distinct in clinic-based studies (OR = 0.59, 95% CI 0.42-0.82) and case-control studies (OR = 0.40, 95% CI 0.26-0.62), but not in population-based studies (OR = 0.95, 95% CI 0.55-1.62) and cohort studies (OR = 0.98, 95% CI 0.81-1.18). Interestingly, studies conducted in Europe (OR = 0.48, 95% CI 0.31-0.77), rather than in North America (OR = 0.91, 95% CI 0.67-1.24), showed the protective effect of thiopurines. CONCLUSIONS This meta-analysis revealed an antineoplastic effect of thiopurines on colorectal neoplasia in patients with IBD, particularly amongst patients with UC.

Abstract
Objective: To construct a dynamic enhanced MR based predictive model for early assessing pathological complete response (pCR) to neoadjuvant therapy in breast cancer, and to evaluate the clinical benefit of the model by using decision curve. Methods: From December 2005 to December 2007, 170 patients with breast cancer treated with neoadjuvant therapy were identified and their MR images before neoadjuvant therapy and at the end of the first cycle of neoadjuvant therapy were collected. Logistic regression model was used to detect independent factors for predicting pCR and construct the predictive model accordingly, then receiver operating characteristic (ROC) curve and decision curve were used to evaluate the predictive model. Results: ΔArea(max) and Δslope(max) were independent predictive factors for pCR, OR=0.942 (95%CI: 0.918-0.967) and 0.961 (95%CI: 0.940-0.987), respectively. The area under ROC curve (AUC) for the constructed model was 0.886 (95%CI: 0.820-0.951). Decision curve showed that in the range of the threshold probability above 0.4, the predictive model presented increased net benefit as the threshold probability increased. Conclusions: The constructed predictive model for pCR is of potential clinical value, with an AUC>0.85. Meanwhile, decision curve analysis indicates the constructed predictive model has net benefit from 3 to 8 percent in the likely range of probability threshold from 80% to 90%.

Abstract
Objective: To explore the high risk factors of stillbirth. Methods: 176 cases of stillbirth were collected in the Obstetrics and Gynecology Hospital of Fudan University from January 1(st), 2010 to December 31(st), 2016. All cases were analyzed retrospectively, including general profile, high risk factors of stillbirth in different years and pregnancy periods. Results: (1) The incidence of stillbirth was 0.178%(176/98 785). Stillbirth occured mostly at 28-28(+6) gestational weeks (10.8%,19/176), and the second peak was 29-29(+6) weeks(10.2%,18/176), while the third common period was 37-37(+6) weeks (9.1%,16/176). After 39 weeks, it maintained at a low level. (2) The top 5 high risk factors of stillbirth were infection (18.2%,32/176), unexplained (13.6%,24/176), hypertention disorders in pregnancy (13.1%, 23/176), umbilical cord torsion (12.5%, 22/176) and fetal malformations (10.2%, 18/176). (3) From 2010 to 2012, the top 3 high risk factors were unexplained, the umbilical cord torsion and infection, while hypertention in pregnancy, infection and fetal malformation became the top 3 high risk factors after 2013. (4) Early stillbirth (20-27(+6) weeks) accounted for 21.6%(38/176); and unexplained (47.4%, 18/38), fetal edema (13.2%, 5/38),infection (13.2%, 5/38), umbilical cord torsion (5.3%, 2/38) were the top 4 high risk factors. Late stillbirth (≥28 weeks) accounted for 78.4%(138/176), with infection (19.6%,27/138), hypertention in pregnancy (15.9%,22/138), umbilical cord torsion (14.5%,20/138) and fetal malformation(12.3%,17/138)being the top 4 high risk factors. Conclusions: More attention should be paid to maternal complications, especially infection and hypertension in pregnancy. Antenatal fetal monitoring, timely termination of pregnancy, standard management of stillbirth and looking for the causes may help reduce the incidence of stillbirth.

Abstract
OBJECTIVES To explore the association between obesity phenotype and the risk of hypertension among Chinese adults. STUDY DESIGN A prospective cohort study. METHODS Two waves of data were collected in 2009 and 2011 by the China Health Nutrition Survey. According to International Diabetes Federation and Chinese obesity criteria, participants were divided into four groups: metabolically healthy non-overweight/obesity (MHNO), metabolically healthy overweight/obesity (MHO), metabolically abnormal non-overweight/obesity (MANO), and metabolically abnormal overweight/obesity (MAO). Logistic regression model was performed to estimate the risk of hypertension with obesity phenotype. RESULTS Among a total of 4604 adults aged 18-65 years at baseline, 467 developed hypertension during the 2-year follow-up period. After adjusting for several potential confounders, significantly increased risks for hypertension were found for participants in MHO (odd ratio [OR]: 1.78, 95% confidence interval [CI]: 1.39-2.27), MANO (OR: 1.71, 95% CI: 1.02-2.86), and MAO (OR: 3.35, 95% CI: 2.54-4.42) group compared with the MHNO group. CONCLUSION Metabolically abnormal individuals, regardless of their body weight status, showed significantly higher risks for hypertension compared with healthy non-overweight/obese group. Furthermore, MHO individuals had significantly increased risk of incident hypertension.

Abstract
Objective:The aim of this study is to study the effect of 3-methyladenine (3-MA) on the autophagy and apoptosis of human laryngeal cancer Hep 2 cells induced by curcumin. Method:The proliferation of human laryngeal cancer Hep2 cells was observed by MTT assay. The autophagy level was detected by AO acridine orange staining. Annexin VFITC/PI double staining was used to detect the apoptosis of Hep2 cells. The expression of LC3, Beclin1, Bcl-2 and Bax protein were detected by Western blot. Result:MTT assay showed that curcumin inhibited the proliferation of Hep2 cells in a dose/time dependent manner. The apoptosis rate of curcumin combined with 3-MA increased (P<0.05). Acridine orange staining showed that 3-MA combined with curcumin could significantly reduce the autophagy level of laryngeal carcinoma Hep2 cells. The expression of Bcl-2, Bclin-1 and LC3 Ⅱ was decreased, while the expression of Bax protein was increased (P<0.05). Conclusion:Curcumin can induce apoptosis of Hep 2 cells and induce the development of protective autophagy. The inhibitory effect of curcumin on the apoptosis of laryngeal carcinoma Hep2 cell line was significantly enhanced by 3-MA.

Abstract
Objective: To investigate the influence of gestational weight gain (GWG) on the incidence of macrosomia, and to establish the reference ranges of GWG based on the incidence of macrosomia. Methods: A multicenter, cross-sectional study was conducted. Totally, 112 485 women were recruited from 39 hospitals in 14 provinces in China. Totally, 61 149 cases were eligible with singleton pregnancies and non-premature deliveries. The associations of pre-pregnancy body mass index (BMI), GWG, newborn gender and gestational diabetes with macrosomia were analyzed with logistic regression. The normal GWG ranges were calculated in all maternal BMI subgroups, based on the normal incidence of macrosomia was set as the range of 5.0% to 10.0%. Results: In this study, the incidence of macrosomia was 7.46% (4 563/611 149). The macrosociam was positive related with maternal height, delivery week, pre-pregnancy BMI, GWG, gestational diabetes, primipara, and male babies significantly (P<0.05), based on unadjusted and adjusted logestic regression. The normal range of GWG 20.0-25.0, 10.0-20.0, 0-10.0 and 0-5.0 kg in subgroups of underweight (pre-pregnancy BMI<18.5 kg/m(2)), normal (18.5-24.9 kg/m(2)), overweight (25.0-29.9 kg/m(2)) and obese (≥30.0 kg/m(2)), respectively. Conclusion: The reference range of GWG in China based on the incidence of macrosomia is established.

Abstract
Objective: To evaluate pre-and early post-transplantation risk factors for acute rejection(AR) in kidney recipients. Methods: This subgroup analysis of a multi-center registry study was conducted on living-donor kidney transplant recipients in China with 10 years of follow-up. This study analyzed 1 255 recipients including 921 males(73.4%) and with a mean age of (33±10)years. Data from patients were first analyzed with univariate analysis and then multivariate analysis was used for finding out the potential risk factors of AR. Results: A total of 106(8.4%) patients were suspected with AR after kidney transplantation, while 1 149 patients were considered as non-AR. Multivariable analysis demonstrated a significant influence of recipient age and cold ischemia time(CIT) on the occurrence of AR(OR: 0.956, 95% CI: 0.923-0.990; OR: 1.006, 95% CI: 1.002-1.011, respectively). The frequency of severe infection was significantly higher in the AR group than non-AR group(38.7% vs 10.8%; P<0.000 1). The occurrence of new-onset diabetes mellitus and tumors was similar in the two groups. Conclusions: Recipient age and CIT are risk factors for AR after living-donor kidney transplantation. Reducing CIT and intensive management of younger recipient could benefit kidney transplant patients.
