Abstract
Background/purpose Excessive host immune response is thought to be an important cause of periodontal tissue damage during periodontitis. The potent chemotaxis produced by locally released chemokines is the key signal to trigger this response. Here, we aimed to investigate the expression of CXC chemokine receptor 1 (CXCR1), and chemokines interleukin-8 (IL-8) and pro-platelet basic protein (PPBP) in human inflammatory gingival tissues compared with healthy tissues. Materials and methods A total of 54 human gingival tissues, 27 healthy and 27 inflammatory samples, were collected. Fifteen specimens of each group were employed for quantitative reverse transcription polymerase chain reaction to determine the mRNA levels of CXCR1, IL-8, and PPBP. Six samples of each group were used for Western blotting to investigate the protein expression of CXCR1 and for enzyme-linked immunosorbent assay to evaluate the protein levels of IL-8 and PPBP, respectively. Results The mRNA levels of chemokine receptor CXCR1, chemokine IL-8, and PPBP in inflammatory gingival tissues were significantly higher than those in healthy controls (P < 0.05). The protein levels of CXCR1, IL-8, and PPBP in inflammatory gingival tissues were also significantly higher than those in healthy gingival tissues (P < 0.05). Conclusion When compared to healthy gingival tissues, the expression of CXCR1, IL-8, and PPBP in inflammatory gingival tissues is higher.

Abstract
Objective: To understand the performance of pulmonary function tests in people aged ≥40 years and its changes in China, and provide evidence for the evaluation of the effect of chronic obstructive pulmonary disease (COPD) prevention and control in China. Methods: The subjects of the survey were from COPD surveillance during 2014-2015 and during 2019-2020, which covered 31 provinces (autonomous regions and municipalities) in China. The survey used multi-stage stratified cluster random sampling method, the trained investigators conducted face-to-face interview to know whether subjects had previous pulmonary function testing or not. Complex sampling weighting was used to estimate the rate of pulmonary function testing in people aged ≥40 years, and the pulmonary function testing rates of the two COPD surveillance periods were compared. Results: A total of 148 427 persons were included in the analysis, including 74 591 persons during 2014-2015 and 73 836 persons during 2019-2020. In 2019-2020, the pulmonary function testing rate in Chinese residents aged ≥40 years was 6.7% (95%CI: 5.2%-8.2%), the rate in men (8.1%, 95%CI: 6.7%-9.6%) was higher than that in women (5.4%, 95%CI: 3.7%- 7.0%), and the rate in urban residents (8.3%, 95%CI: 6.1%-10.5%) was higher than that in rural residents (4.4%, 95%CI: 3.8%-5.1%). The rate of pulmonary function testing increased with the increase of education level. During 2019-2020, the residents with history of chronic respiratory diseases had the highest rate of pulmonary function testing (21.2%, 95%CI: 16.8%-25.7%), followed by the residents with respiratory symptoms (15.1%, 95%CI: 11.8%-18.4%) , the pulmonary function testing rate in those who knew the name of chronic respiratory disease was higher than that in those who did not knew the name of respiratory disease, and the pulmonary function testing rate in former smokers was higher than that in current smokers and non-smokers. Those exposed to occupational dust and/or harmful gases had a higher rate of pulmonary function testing compared with those who were not exposed, and those who used polluted fuels indoors had a lower rate of pulmonary function testing than those who did not use polluted fuels indoors (all P<0.05). Compared with 2014-2015, the pulmonary function testing rate in residents aged ≥40 years in China increased by 1.9 percentage points during 2019-2020, and the rate of pulmonary function testing in groups with different characteristics all increased, and the rates of pulmonary function testing increased by 7.4 percentage points and 7.1 percentage points in residents with respiratory symptoms and in those with history of chronic respiratory diseases (all P<0.05). Conclusions: Compared with 2014-2015, the rate of pulmonary function testing increased in China during 2019-2020 and the increase in residents with history of chronic respiratory diseases and respiratory symptoms was relatively obvious, but the overall pulmonary function testing rate was still at a low level. Effective measures should be taken to further increase the rate of pulmonary function testing.

Abstract
Objective: To understand the prevalence of smoking and its change in adults aged ≥40 years in China and provide evidence for the development of chronic obstructive pulmonary disease (COPD) prevention and control strategies. Methods: The data of this study were obtained from COPD surveillance in China during 2014-2015 and during 2019-2020. The surveillance covered 31 provinces (autonomous regions and municipalities). A multi-stage stratified cluster random sampling were used to select residents aged ≥40 years, and face-to-face interviews were conducted to collect the information about their tobacco use. After complex sampling weighting of the samples, the current smoking rate, average age to start smoking and average daily cigarette consumption of people with different characteristics during 2019-2020 were estimated, and the changes in the current smoking rate and average daily cigarette consumption were analyzed from 2014-2015 to 2019-2020. Results: During 2019-2020, the current smoking rate in adults aged ≥40 years was 27.2%, and the rate was much higher in men (52.1%) than in women (2.5%).The average age of the smokers to start smoking was 20.0 years old, and men usually started smoking at younger age (19.6 years) compared with women (27.9 years). The average daily cigarette consumption of daily smokers was 18.0 sticks, and the consumption of men (18.3 cigarettes) was higher than that of women (11.1 cigarettes). Compared with the surveillance results during 2014-2015, the current smoking rate had decreased by 2.8 percentage points in the general population, 4.1 percentage points in males, 1.6 percentage points in females, and the urban and rural areas fell by 3.1 percentage points and 2.5 percentage points, respectively. The average daily cigarette consumption decreased by 0.6 sticks. Conclusions: In recent years, the current smoking rate and average daily cigarette consumption in adults aged ≥40 years decreased in China, but smoking is still common in more than quarter of this population and more than half of men aged ≥40 years. It is necessary to take targeted tobacco control measures based on population and regional characteristics to further reduce the smoking level of the population.

Abstract
β decay of proton-rich nuclei plays an important role in exploring isospin mixing. The β decay of ^{26}P at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in ^{26}Si are unambiguously identified through β-delayed two-proton emission (β2p). Angular correlations of two protons emitted from ^{26}Si excited states populated by ^{26}P β decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the ^{26}Si IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in β-decay experiments.

Abstract
Subgroup J Avian leukosis virus (ALV-J) is an important pathogen of poultry tumor diseases. Since its discovery, it has caused significant economic losses to the poultry industry. Thus, the rapid detection of molecular level with strong specificity is particularly important whether poultry are infected with ALV-J. In this study, we designed primers and probe for real-time fluorescent reverse-transcription recombinase-aided amplification assay (RT-RAA) based on the ALV-J gp85 sequence. We had established a real-time fluorescent RT-RAA method and confirmed this system by verifying the specificity and sensitivity of the primers and probe. In addition, repeatability tests and clinical sample regression tests were used for preliminary evaluation of this detection method. The sensitivity of established method was about 101 copies/μL, and the repeatability of the CV of the CT value is 4%, indicating repeatability is good. Moreover, there was no cross-reactivity with NDV, IBV, IBDV, H9N2, MDV, and REV, and other avian leukosis virus subgroups, such as subgroups A, B, C, D, K and E. Importantly, the real-time fluorescent RT-RAA completed the test within 30 min at a constant temperature of 41°C. Forty-two clinical samples with known background were tested, and the test results were coincided with 100%. Overall, these results suggested that the real-time fluorescent RT-RAA developed in this study had strong specificity, high sensitivity, and good feasibility. The method is simple, easy, and portable, that is suitable for clinical and laboratory diagnosis, and provides technical support for the prevention and control of ALV-J.

Abstract
β-delayed one-proton emissions of ^{22}Si, the lightest nucleus with an isospin projection T_{z}=-3, are studied with a silicon array surrounded by high-purity germanium detectors. Properties of β-decay branches and the reduced transition probabilities for the transitions to the low-lying states of ^{22}Al are determined. Compared to the mirror β decay of ^{22}O, the largest value of mirror asymmetry in low-lying states by far, with δ=209(96), is found in the transition to the first 1^{+} excited state. Shell-model calculation with isospin-nonconserving forces, including the T=1, J=2, 3 interaction related to the s_{1/2} orbit that introduces explicitly the isospin-symmetry breaking force and describes the loosely bound nature of the wave functions of the s_{1/2} orbit, can reproduce the observed data well and consistently explain the observation that a large δ value occurs for the first but not for the second 1^{+} excited state of ^{22}Al. Our results, while supporting the proton-halo structure in ^{22}Al, might provide another means to identify halo nuclei.

Abstract
OBJECTIVE To understand the situation of Anisakis infection of in market-available marine fish in Dongtai City, so as to provide the evidence for the assessment of the risk of human Anisakis infections. METHODS Raw and fresh marine fish caught in the sea of Dongtai City for sale were collected in 2018. The fish were weighted and dissected for the identification of Anisakis, and the prevalence and intensity of Anisakis infections were calculated. In addition, the correlation between the weight of Anisakis-infected marine fish and the infection intensity of Anisakis was examined. RESULTS There were four species of marine fish infected with Anisakis, including Trichiurus haumela, Scomberomorus niphonius, Pneumatophorus japonicus and Larimichthys polyactis. Among the 149 fish samples, there were 78 with Anisakis infections, with a prevalence rate of 52.35%. The prevalence of Anisakis infection was 100.00% (28/28), 30.00% (9/30), 0 (0/30), 53.33% (16/30) and 80.65% (25/31) in T. haumela, S. niphonius, cuttle fish, P. japonicus and L. polyactis, respectively. A total of 1 049 Anisakis worms were collected, and the overall intensity of infection was 13.45 worms per fish. Spearman correlation analysis showed a positive correlation between the weight of T. haumela and the intensity of Anisakis infection (rs = 0.38, P = 0.047), and no correlation was found in other fish species. CONCLUSIONS There is a high rate of Anisakis infection in marine fish along the offshore areas of Dongtai City. Intensification of health education is required and healthy and safe dietary habits are encouranged.

Abstract
Background Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that causes long-lasting inflammation and ulcers in the human digestive tract. The repair role of TLR4 in the intestinal epithelium is still unknown. Methods By comparing to wild-type (WT) mice, Toll-like receptor 4 (TLR4)-knockout mice (TLR4-KO) were used as dextran sulfate sodium (DSS)-induced colitis models to explore the role of TLR4 signaling in intestinal injury. High-throughput RNA-Seq, RT-qPCR and ELISA were performed to screen and verify key differences in gut genes between WT and TLR4-KO mice. Functional study of core dysregulated factors was performed in intestinal cell lines. Results We found that DSS-induced intestinal injury was aggravated by LPS (TLR4 agonist) and TLR4-KO. When compared to WT mice, IL6, CCL2, CSF3, IL11, Ccnb1, Ccnd1 and TNF-α significantly decreased and Fas and FasL have increased in the gut of TLR4-KO mice. IL6, CCL2, CSF3, Fas and FasL have all increased in CT-26 cells treated with LPS. Combined with the above data and KEGG enrichment, it can be assumed that TLR4-KO might aggravate DSS-induced intestinal damage by attenuating cell cycle, cytokine-cytokine receptor interaction, and Toll-like receptor signaling pathway, and enhancing the apoptosis pathway. In the functional study of core dysregulated factors, it was found that LPS, IL6, IL11, CSF3, CCL2, S100A8, S100A9 and Mmp3 have improved viability of colon cancer cell lines and decreased apoptosis rate of mouse colon cancer cells when these were treated with DSS. However, Jo-2 (Fas agonistic monoclonal antibody) played the opposite role in colon cancer cells treated with DSS. Conclusions TLR4 had a repairing effect on DSS-induced intestinal damage and it up-regulate IL6, CCL2 and CSF3. Fas and FasL enhanced DSS-induced colon injury in mice, but might have little to do with TLR4 signaling.

Abstract
Low temperature is one of the important factors limiting wheat yield in cold regions. Expansins are nonenzymatic proteins that loosen cell walls and play important roles in diverse biological processes related to cell wall modification, including development and stress tolerance. Many studies have shown that expansins are involved in resistance to various abiotic stresses, such as heat and drought. However, the role of expansins in response to low-temperature stress remains unclear. Based on our previous transcriptome data of a winter wheat cultivar Dongnongdongmai 2 (DN2), we found that one of the expansin genes, TaEXPA8, was significantly induced by low temperature, indicating a role for TaEXPA8 in cold resistance. In this study, the paralogous TaEXPA8 genes TaEXPA8-A, TaEXPA8-B and TaEXPA8-D were cloned by RT-PCR. These three genes were then transformed into Arabidopsis by the floral dip method. Expression patterns of TaEXPA8 genes in different tissues and in response to several abiotic stresses and hormones were detected by quantitative real-time PCR (qRT-PCR). The results showed that TaEXPA8-A and TaEXPA8-B were expressed mainly in roots, while TaEXPA8-D was expressed predominantly in flowers. TaEXPA8 genes were induced by low-temperature and drought. The overexpression of TaEXPA8-B and TaEXPA8-D enhanced low-temperature resistance and had increased superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) activity and soluble protein, MDA and proline content. In summary, our study suggested that the expansins TaEXPA8-B and TaEXPA8-D are involved in the response to low temperature and possibly play a role in cold resistance by activating the protective enzyme system.

Abstract
Inflammation is as an important component of intestinal tumorigenesis. The activation of Toll‐like receptor 4 (TLR4) signalling promotes inflammation in colitis of mice, but the role of TLR4 in intestinal tumorigenesis is not yet clear. About 80%–90% of colorectal tumours contain inactivating mutations in the adenomatous polyposis coli (Apc) tumour suppressor, and intestinal adenoma carcinogenesis in familial adenomatous polyposis (FAP) is also closely related to the germline mutations in Apc. The ApcMin/+ (multiple intestinal neoplasia) model mouse is a well‐utilized model of FAP, an inherited form of intestinal cancer. In this study, ApcMin/+ intestinal adenoma mice were generated on TLR4‐sufficient and TLR4‐deficient backgrounds to investigate the carcinogenic effect of TLR4 in mouse gut by comparing mice survival, peripheral blood cells, bone marrow haematopoietic precursor cells and numbers of polyps in the guts of ApcMin/+ WT and ApcMin/+ TLR4−/− mice. The results revealed that TLR4 had a critical role in promoting spontaneous intestinal tumorigenesis. Significant differential genes were screened out by the high‐throughput RNA‐Seq method. After combining these results with KEGG enrichment data, it was determined that TLR4 might promote intestinal tumorigenesis by activating cytokine‐cytokine receptor interaction and pathways in cancer signalling pathways. After a series of validation experiments for the concerned genes, it was found that IL6, GM‐CSF (CSF2), IL11, CCL3, S100A8 and S100A9 were significantly decreased in gut tumours of ApcMin/+ TLR4−/− mice compared with ApcMin/+ WT mice. In the functional study of core down‐regulation factors, it was found that IL6, GM‐CSF, IL11, CCL3 and S100A8/9 increased the viability of colon cancer cell lines and decreased the apoptosis rate of colon cancer cells with irradiation and chemical treatment.

Abstract
Ulcerative colitis2 (UC) is an inflammatory bowel disease3 (IBD) that causes long-lasting inflammation and ulcers in the human digestive tract. The repair function of TLR4 in the intestinal epithelium is still unknown. Here, wild-type4 (WT) mice, TLR4-knockout mice5 (KO; TLR4-/-) and commensal-depleted mice were used as dextran sulfate sodium6 (DSS)-induced or radiation-induced colitis and injury models to explore the role of TLR4 signaling in intestinal injury. Exogenous lipopolysaccharide7 (LPS) promoted DSS-induced inflammatory cytokines and aggravated intestinal damage. TLR4 deficiency and commensal bacterial depletion inhibited the toxic effects of LPS, but these mice were more susceptible to DSS-induced and radiation-induced intestinal damage. Compared with WT mice, neither DSS nor radiation promoted production of more inflammatory cytokines in the guts of TLR4-KO and commensal-depleted mice. Introducing the cytokine repair factors, PGE2 and GM-CSF, increased the cytokine levels in the guts of DSS-induced colitis mice. We hypothesized that TLR4 and its ligands repaired the epithelium after DSS-induced and radiation-induced intestinal damage by upregulating PGE2 and GM-CSF. Transwell migration assays suggested that LPS, IL6, TNF, PGE2 and GM-CSF promoted intestinal cell migration, and cell viability analysis suggested that these factors protected against radiation-induced intestinal damage. Our data underscore the importance of the balancing role of TLR4 in intestinal injury and repair.

Abstract
Objective: To investigate the efficacy of arthroscopic synovectomy on refractory knee arthritis complicated with popliteal cyst. Methods: Patients diagnosed as rheumatoid arthritis (RA) or spondyloarthritis (SpA) with refractory knee arthritis who underwent knee arthroscopic synovectomy in our hospital from 2010 to 2017 were enrolled, including 20 patients (16 RA, 4 SpA) with popliteal cyst. Clinical data, RA disease activity score (DAS28), SpA back pain score, etc, were collected to evaluate the efficacy of knee surgery. Results: Erythrocyte sedimentation rate (ESR) [58(17, 79)mm/1h vs. 19(9, 30)mm/1h, P< 0.001],C reactive protein (CRP) [3.72(0.92,8.14) mg/L vs. 0.85(0.10,3.08) mg/L,P<0.001], rheumatoid factor [64.6(20.2,193.3) vs. 20.5(10.0,58.4),P<0.001], DAS28 score(4.67±1.25 vs. 2.81±1.23,P<0.001), knee joint discomfort score [5(4,6) vs. 2(1,3),P<0.001] and the volume of knee joint effusion by ultrasound (P<0.05) in 95 RA patients were significantly decreased compared to those before operation. ESR [27(12,54)mm/1h vs. 20 (16,28) mm/1 h,P<0.001], CRP [3.27(1.06,6.95) mg/L vs. 1.41(0.34,3.03)mg/L,P<0.001],knee discomfort score [2(0,5) vs. 1(0,3),P<0.05], back pain visual analogue score (VAS) [5(4,5) vs. 2(1,3), P<0.001], and the volume of knee joint effusion by ultrasound (P<0.001) in 58 SpA patients were significantly lower than those before the operation.The rate [16.84%(16/95) vs. 6.32%(6/95),P=0.023] and grading (P=0.007) of popliteal cyst in RA were decreased after the operation. No statistically difference was observed in the rate [6.90% (4/58) vs. 5.17%(3/58), P=0.697] of popliteal cyst in patients with SpA, yet with a trend of decrease in 4 patients. Conclusion: This study provide evidence that knee arthroscopic synovectomy has a good effect for refractory knee arthritis, which can reduce disease activity, improve joint symptoms and decrease the grading of popliteal cyst.

Abstract
Objective: To analyze the interpretation results on the pathogenic classification of KCNH2 variants and SCN5A variants of long QT syndrome (LQTS) based on American College of Medical Genetics and Genomics (ACMG) guidelines by 4 clinical gene screening agencies from Beijing. Methods: Pathogenic classification of 16 variants in KCNH2 and SCN5A was made by 4 clinical gene screening agencies from Beijing based on ACMG guideline. Krippendorff's alpha was used to assess the inter-agency variation consistency. Results: All 4 agencies made pathogenic assessment on all the variants and provided the interpretation results for the classification. For the eight variants from the patients with LQTS, the consistency of classification was only 1/8 and the alpha test value was - 0.01. For the eight variables from incidental findings, the consistency of classification was 4/8 and the alpha test value was 0.407. Evidence analysis of the 4 variants with large differences in classification among agencies showed that the main reasons for the discrepancies originated from the comprehensiveness of the literature search and the inconsistency of the subjective determination of the evidence grade. Conclusion: The consistency of the pathogenic classification of LQTS gene variants based on ACMG guidelines among clinical gene screening agencies from Beijing is poor, which will result in great impact on the clinical treatment strategies of the patients with LQTS. The standardization of pathogenic evaluation of variants in clinical gene screening agencies needs to be improved urgently.

Abstract
OBJECTIVE To explore the impact of IL10-592 (rs1800872) single nucleic acid polymorphism (SNP) on the prognosis of HLA matched unrelated hematopoietic stem cell transplantation (HSCT). METHODS The polymorphism of IL10-592 in 104 recipient-donor pairs and 100 healthy volunteers was analyzed with sequence based typing (SBT). RESULTS When the genotype of IL10-592 in donors and recipients matched, AA/AA genotype had higher incidence of Ⅲ-Ⅳ aGVHD than AC/AC or CC/CC genotype (47.1%, 3.7%, 0, P=0.002). When the genotype of IL10-592 in donors and recipients mismatched, recipients with AC genotype or donors with AA genotype, there was significant different incidence of Ⅲ-ⅣaGVHD among donors or recipients with different genotype (P=0.046, P=0.041). The recipients with AA genotype had higher incidence of Ⅲ-Ⅳ aGVHD than AC or CC genotype (27.8% vs 10.2%, 11.1%; P=0.072), and higher incidence of intestinal aGVHD (22.2% vs 5.1%,11.1%; P=0.040) , lower incidence of 2-year overall survival (OS: 48.2% vs 75.1%, 85.7%; P=0.002), lower incidence of 2 year disease free survival (DFS: 48.5% vs 66.3%, 76.2%; P=0.045). Patients had higher incidence of Ⅲ-Ⅳ aGVHD with donors of AA genotype than with donors of AC or CC genotype (26.5% vs 8.9%, 0; P= 0.024), and higher incidence of intestinal aGVHD (20.4% vs 4.4%, 0; P=0.026). In multivariate analysis, the genotype of IL10-592AA in recipients and donors had increased risk of Ⅲ-Ⅳ aGVHD (OR=3.3, P= 0.049; OR=3.9, P=0.043). There were no statistical differences on the incidence of cGVHD and relapse. CONCLUSION In HLA-10/10 matched unrelated HSCT, the presence of IL10-592 AA genotype in recipients and/or donors is an adverse factor for Ⅲ-ⅣaGVHD, worse OS and 2-year DFS.
