Abstract
Excessive fluoride intake during enamel development can affect enamel mineralization, leading to dental fluorosis. However, its potential mechanisms remain largely unexplored. In the present study, we aimed to investigate the impact of fluoride on the expressions of RUNX2 and ALPL during mineralization and the effect of TGF-β1 administration on fluoride treatment. A dental fluorosis model of newborn mice and an ameloblast cell line ALC were both used in the present study. The mice of the NaF group, including the mothers and newborns, were fed with water containing 150 ppm NaF after delivery to induce dental fluorosis. The mandibular incisors and molars showed significant abrasion in the NaF group. Immunostaining, qRT-PCR, and Western blotting analysis indicated that exposure to fluoride markedly down-regulated RUNX2 and ALPL in mouse ameloblasts and ALCs. Besides, fluoride treatment significantly decreased the mineralization level detected by ALP staining. Furthermore, exogenous TGF-β1 up-regulated RUNX2 and ALPL and promoted mineralization, while the addition of SIS3 could block such TGF-β1-induced up-regulation. In TGF-β1 conditional knockout mice, the immunostaining of RUNX2 and ALPL was weaker compared with wild-type mice. Exposure to fluoride inhibited the expressions of TGF-β1 and Smad3. Co-treatment of TGF-β1 and fluoride up-regulated RUNX2 and ALPL compared with the fluoride alone treatment, promoting mineralization. Collectively, our data indicated that TGF-β1/Smad3 signaling pathway was necessary for the regulatory effects of fluoride on RUNX2 and ALPL, and the fluoride-induced suppression of ameloblast mineralization was mitigated by activating TGF-β1/Smad3 signaling pathway.

Abstract
Objective: To investigate the influence of obstructive sleep apnea syndrome (OSAS) on myocardial work and prognosis in patients with acute myocardial infarction (AMI). Methods: Patients with complete follow-up data diagnosed with AMI who were admitted to the Second Affiliated Hospital of Suzhou University due to chest pain within 24 hours attacks from February 2020 to January 2022 were retrospective enrolled in the study and were split into two groups based on sleep apnea hypoventilation index (AHI): OSAS group (AHI≥5/h) and non-OSAS group (AHI<5/h). Follow up for (12.4±0.1) months. There were finally 210 AMI patients including 130 males and 80 females with (69.6±9.4) years, ranging from 36 to 83 years. The general characteristics, haematological index, echocardiographic parameters, myocardial work (MW) and the occurrence of major adverse cardiac events (MACE) in 1 year between the two groups were quantified. Logistic regression analysis and receiver operating characteristic (ROC) curve were used to assess the risk of MACE in patients with AMI. Results: There were 50 cases in the OSAS group and 160 cases in the non-OSAS group. Compared with the non-OSAS group, OSAS group demonstrated higher BMI,neck circumference, Killip grade,GRACE score,ESS score,SYNTAX score, the number of diseased vessels and higher prevalence of hypertension, hyperlipidemia and smoking history. The differences were statistically significant (P<0.05). There were also statistically significant differences in sleep study result and hematological indexesof of cTnT, NT-ProBNP, and creatinine between the two groups (P<0.05). The general work index (GWI) of the OSAS group was lower than that of the non-OSAS group [(870.1±435.6) vs (1 005.0±313.6) mmHg% (1 mmHg=0.133 kPa), P=0.017]; The general myocardial active work (GCW) of the OSAS group was lower than that of the non-OSAS group [(1 046.7±472.2) vs (1 262.7±274.9) mmHg%, P=0.003]; The general work efficiency (GWE) of the OSAS group was lower than that of the non-OSAS group [(79.8±14.2)% vs (84.5±5.8)%, P=0.001]; The general reactive power (GWW) of the OSAS group was higher than that of the non-OSAS group [(312.2±163.2) vs (264.0±85.1) mmHg%, P=0.007]. There were 10 cases (20.0%) of MACE in the OSAS group and 13 cases (8.1%) in the non OSAS group, with a statistically significant difference (P=0.001).The combination of decreased OSAS (OR=4.039, 95%CI: 1.159-6.918), decreased myocardial work, including GCW [OR=0.850 (95%CI: 0.742-0.958)], GWE [OR=0.871 (95%CI: 0.818-0.924)], GWI (OR=0.862, 95%CI: 0.732-0.991), increased GWW (OR=2.425, 95%CI: 1.482-3.368), and increased GRACE score (OR=3.775, 95%CI: 2.314-5.236) increased the risk of MACE in AMI patients (all P<0.05). The area under the ROC curve (AUC) for predicting MACE in AMI using OSAS+myocardial work+GRACE score was 0.779 (95%CI: 0.717-0.834), with a sensitivity of 65.2% and a specificity of 84.5%. After the combination of the three, there were statistically significant differences compared to the AUC of combined OSAS, GRACE score, and myocardial work (all P<0.05). Conclusions: The MW of AMI patients with OSAS decreased compared to those without OSAS. The combination of OSAS and MW can improve the predictive value of MACE in patients with AMI.

Abstract
As fresh ornamental crops, vase life and post-harvested quality of cut flowers have attracted much attention. Flower color fading is the prominent defect in red and purple cut flowers, especially in cut chrysanthemum which have a relative long vase life. Here, the effect of sucrose on change in anthocyanin contents during the vase life of 'Dante Purple' cut chrysanthemum was studied. Results showed that 500 mM sucrose as holding solution could significantly delay the decrease in anthocyanin content and maintain the ornamental value for as long as 38 vase days. Moreover, the sucrose also increased the flower diameter, soluble sugar contents and total antioxidant capacity, while decreasing the malondialdehyde contents. Further studies suggested that the transcript levels of anthocyanin biosynthetic genes and transcription factors, CmMYB6 and CmMYB#7, had continuously decreased during the vase life. The changes in these genes expression patterns was retarded by the sucrose treatment, except for CmMYB#7 which is a repressor of anthocyanin biosynthesis gene expression. The decline in relative expression of CmMYB#7 was accelerated by sucrose. These results have supplied clues to study the mechanism whereby sucrose serves as a signal molecule to regulate anthocyanin biosynthesis.

Abstract
Objective: To investigate the clinicopathological characteristics of plurihormonal PIT1-lineage pituitary neuroendocrine tumors. Methods: Forty-eight plurihormonal PIT1-lineage tumors were collected between January 2018 and April 2022 from the pathological database of Sanbo Brain Hospital, Capital Medical University. The related clinical and imaging data were retrieved. H&E, immunohistochemical and special stains were performed. Results: Out of the 48 plurihormonal PIT1-lineage tumors included, 13 cases were mature PIT1-lineage tumors and 35 cases were immature PIT1-lineage tumors. There were some obvious clinicopathological differences between the two groups. Clinically, the mature plurihormonal PIT1-lineage tumor mostly had endocrine symptoms due to increased hormone production, while a small number of immature PIT1-lineage tumors had endocrine symptoms accompanied by low-level increased serum pituitary hormone; patients with the immature PIT1-lineage tumors were younger than the mature PIT1-lineage tumors; the immature PIT1-lineage tumors were larger in size and more likely invasive in imaging. Histopathologically, the mature PIT1-lineage tumors were composed of large eosinophilic cells with high proportion of growth hormone expression, while the immature PIT1-lineage tumors consisted of chromophobe cells with a relatively higher expression of prolactin; the mature PIT1-lineage tumors had consistently diffuse cytoplasmic positive staining for keratin, while the immature PIT1-lineage tumors had various expression for keratin; the immature PIT1-lineage tumors showed more mitotic figures and higher Ki-67 proliferation index; in addition, 25.0% (12/48) of PIT1-positive plurihormonal tumors showed abnormal positive staining for gonadotropin hormones. There was no significant difference in the progression-free survival between the two groups (P=0.648) by Kaplan-Meier analysis. Conclusions: Plurihormonal PIT1-lineage tumor belongs to a rare type of PIT1-lineage pituitary neuroendocrine tumors, most of which are of immature lineage. Clinically increased symptoms owing to pituitary hormone secretion, histopathologically increased number of eosinophilic tumor cells with high proportion of growth hormone expression, diffusely cytoplasmic keratin staining and low proliferative activity can help differentiate the mature plurihormonal PIT1-lineage tumors from the immature PIT1-lineage tumors. The immature PIT1-lineage tumors have more complicated clinicopathological characteristics.

Abstract
PURPOSE/OBJECTIVE(S) Proton-acoustic (PA) image has shown great potential to provide real-time 3D dose verification of proton therapy. However, the PA image quality suffers from severe limited view artifacts, which significantly impairs its accuracy for dose verification. In this study, we developed a hybrid-supervised deep learning method for PA reconstruction to address the limited-view issues. MATERIALS/METHODS Our method consists of two stages. In the first stage, a transformer-based network was proposed to reconstruct initial pressure maps from protoacoustic signals. The network was first trained using supervision by the iteratively reconstructed pressure map and then fine-tuned using transfer learning and self-supervision based on the data fidelity constraint. In the second stage, the PA image was further enhanced by a 3D U-net. The final PA images were converted to dose maps using conversion coefficients derived from CT images. Data from 126 prostate cancer patients treated by proton therapy were collected under an IRB protocol and were split into 86 and 40 patients for model training and testing, respectively. Data of each patient contains the planning CT scan, the corresponding clinical treatment plan, and the dose map calculated by commercial software. The radiofrequency signals were generated by performing proton acoustic simulation based on CT images and the ground truth pressure map derived from the treatment plan. An ultrasound detector matrix with 64 × 64 size and 500kHz central frequency was simulated under the perineum to acquire the signals in the prostate area. In the testing results, the method's accuracy was evaluated using Root-mean-squared-error (RMSE) and structural-similarity-index-measure (SSIM) between the reconstructed and ground truth pressure map and dose distribution. RESULTS Testing results showed that the reconstructed pressure map achieved an average RMSE/SSIM of 0.0292/0.96, demonstrating excellent 3D information with details. Dose maps derived from the pressure map achieved an average RMSE/SSIM of 0.018/0.99 with a gamma index of 94.7% and 95.7% for 1%/3 mm and 1%/5 mm criteria compared to the ground truth dose maps. The reconstruction time was 6s, which can be further reduced using GPU. CONCLUSION Our study achieves start-of-the-art performance in the challenging task of direct reconstruction from limited-view radiofrequency signals, demonstrating the great promise of PA imaging as a highly efficient and accurate tool for in-vivo 3D proton dose verification. Such high-precision 3D online dose verification can substantially reduce the range uncertainties of proton therapy to significantly improve its precision and outcomes.

Abstract
Anaphylaxis is the most severe allergic reaction, demanding immediate management by health care providers, which is currently underdiagnosed and undertreated in China. In addition to the classic IgE-mediated pathway, non-IgE dependent pathway has also been extensively studied in the pathogenesis of anaphylaxis. Recently, the atypical symptoms induced by widespread used monoclonal antibodies and biologics have been reported. The goal of this article is to recognize the phenotypes (triggers and presentation) and understand its characteristics through endotypes (mechanisms) of anaphylaxis. Ultimately, the aim is to help allergists and health care providers guide a precision approach to diagnose and manage of anaphylaxis.

Abstract
Light quality is a vital environmental signal used to trigger growth and to develop structural differentiation in plants, and it influences morphological, physiological, and biochemical metabolites. In previous studies, different light qualities were found to regulate the synthesis of anthocyanin. However, the mechanism of the synthesis and accumulation of anthocyanins in leaves in response to light quality remains unclear. In this study, the Loropetalum chinense var. rubrum "Xiangnong Fendai" plant was treated with white light (WL), blue light (BL), ultraviolet-A light (UL), and blue light plus ultraviolet-A light (BL + UL), respectively. Under BL, the leaves were described as increasing in redness from "olive green" to "reddish-brown". The chlorophyll, carotenoid, anthocyanin, and total flavonoid content were significantly higher at 7 d than at 0 d. In addition, BL treatment also significantly increased the accumulation of soluble sugar and soluble protein. In contrast to BL, ultraviolet-A light increased the malondialdehyde (MDA) content and the activities of three antioxidant enzymes in the leaves, including catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD), in varying degrees over time. Moreover, we also found that the CRY-like gene, HY5-like gene, BBX-like gene, MYB-like gene, CHS-like gene, DFR-like gene, ANS-like gene, and UFGT-like gene were significantly upregulated. Furthermore, the SOD-like, POD-like, and CAT-like gene expressions related to antioxidase synthesis were found under ultraviolet-A light conditions. In summary, BL is more conducive to reddening the leaves of "Xiangnong Fendai" and will not lead to excessive photooxidation. This provides an effective ecological strategy for light-induced leaf-color changes, thereby promoting the ornamental and economic value of L. chinense var. rubrum.

Abstract
Gonorrhea, caused by Neisseria gonorrhoeae (N. gonorrhoeae), is a persistent global public health threat. The development of low-cost, point-of-care testing is crucial for gonorrhea control, especially in regions with limited medical facilities. In this study, we integrated CRISPR/Cas12a reaction with recombinase polymerase amplification (RPA) to provide a simple and adaptable molecular detection method for N. gonorrhoeae. The RPA-Cas12a-based detection system developed in this study enables rapid detection of N. gonorrhoeae within 1 h without the use of specialized equipment. This method is highly specific for identifying N. gonorrhoeae without cross-reactivity with other prevalent pathogens. Furthermore, in the evaluation of 24 clinical samples, the detection system demonstrates a 100% concordance rate with traditional culture, which is being used clinically as a reference method. Overall, the RPA-Cas12a-based N. gonorrhoeae detection has the advantages of rapidity, portability, low-cost, no special equipment required, and strong operability, and has a high potential for application as a self-testing and point-of-care diagnosis, which is critical for the clinical management of gonorrhea in developing countries lacking medical equipment.

Abstract
This research mainly focused on the leaf color change and photosystem function differentiation between Loropetalum chinense and its variety L. chinense var. rubrum under heat stress, which were tightly concerned about their ornamental traits and growth. L. chinense 'Xiangnong Xiangyun' (X) and L. chinense var. rubrum 'Xiangnong Fendai' (F) and L. chinense var. rubrum 'Hei Zhenzhu' (H) were chosen to be experimented on to investigate whether leaf color morphology and pigment composition could influence the adaptability of plants to high temperature in order to select foliage plants which posses stable leaf color and better adaptability for hot regions. The plants were cultured in hot environment (40 °C/33 °C, day/night) and normal environment (25 °C/18 °C, day/night). Phenotype and anatomic observation of three cultivars were made and leaf color indices and pigment contents were measured. During the experiment, H and F gradually turned green, total anthocyanins contents significantly decreased in them, however, chlorophyll b contents increased in all three cultivars. In addition, the initial fluorescence (Fo) decreased in X, while increased in H and F. For the maximum fluorescence (Fm) and maximum photochemical efficiency of PSII (Fv/Fm), they only increased in H and decreased in both F and X. The non-photochemical chlorophyll fluorescence quenching (NPQ) also increased in H and decreased in F. For X, it increased at first then gradually decreased. The coefficient of photochemical quenching all increased at first then gradually decreased. Correlation analysis between showed that there was relatively strong connection between anthocyanins, flavonoids and chlorophyll fluorescence parameters, especially NPQ, proved anthocyanins and flavonoids might not only involved in enriching leaf color, but also interfered with the protection of photosystem. Generally speaking, we found higher anthocyanin and flavonoids content level not only dramatically enriched the leaf color of L. chinense var. rubrum cultivars, but also offered more potential antioxidant to keep their normal growth when encountered heat stress.

Abstract
OBJECTIVES Dietary Approaches to Stop Hypertension (DASH) pattern has been found to aid in the reduction of obesity, oxidative stress, and chronic inflammation, which are all strongly linked to the development of head and neck cancer (HNC). Nevertheless, no epidemiological studies have investigated the association between this dietary pattern and HNC risk. This study was conducted with the purpose of bridging this gap in knowledge. DESIGN A prospective cohort study involving 98,459 American adults aged 55 years and older. SETTING AND PARTICIPANTS Data were drawn from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Trial. In the present study, participants with dependable energy intake data who furnished baseline and dietary history information were identified as the study population. METHODS Diet was assessed by food frequency questionnaires and the DASH score was calculated to assess each participant's adherence to DASH eating pattern. Cox proportional hazards models were used to calculate multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the occurrence of HNC. To visualize the variation in cancer risk for HNC and its subtypes across the entire spectrum of DASH scores, restricted cubic spline plots were utilized. Additionally, a series of predefined subgroup analyses were performed to identify potential effect modifiers, and several sensitivity analyses were conducted to assess the stability of the findings. RESULTS During a follow-up period of 871,879.6 person-years, 268 cases of HNC were identified, comprising 161 cases pertaining to oral cavity and pharynx cancers, as well as 96 cases of larynx cancer. In the fully adjusted model, adherence to the DASH diet was associated with a remarkable 57% reduction in the risk of HNC when comparing extreme quartiles (HR quartile 4 vs 1: 0.43; 95% CI: 0.28, 0.66; P for trend < 0.001). The restricted cubic spline plots demonstrated a linear dose-response relationship between the DASH score and the risk of HNC as well as its subtypes. Subgroup analysis revealed that the protective effect of the DASH diet against HNC was particularly pronounced in individuals with lower daily energy intake. The primary association remained robust in the sensitivity analysis. CONCLUSIONS In American middle-aged and older population, adherence to the DASH diet may help prevent HNC, particularly for individuals with lower daily energy intake.

Abstract
PURPOSE This present study is aimed at exploring the FGB expression in breast cancer (BC) and the role of FGB in BC. METHODS A total of 150 pairs of BC tissues and adjacent tissues from BC surgery patients were collected. RT-qPCR was utilized to evaluate the mRNA expression of FGB and miR-877-5p. Immunohistochemistry was applied to evaluate the protein expression of FGB. Chi-square test was performed to evaluate the relationship between FGB expression level and clinical characteristics. Cell proliferation was examined using CCK-8 assay. Cell invasion was evaluated by transwell assay. Flow cytometry assay was applied to measure cell apoptosis. The protein expression was evaluated by western blot. BALB/C nude mice were used to establish the xenograft tumor model. RESULTS FGB was more highly expressed in BC tumor, and the expression of FGB was relevant to TNM stage and lymph node metastasis and showed a positive correlation. FGB was proved to be directly regulated via miR-877-5p and enhanced proliferation and invasion of BC cells. FGB downregulation markedly inhibited the tumor growth, including tumor weight and volume. In addition, the Ki-67 expression was observably declined in the sh-FGB group. The protein expression of E-cadherin was markedly raised in the sh-FGB group while the protein expression of N-cadherin and vimentin was markedly declined in the sh-FGB group. CONCLUSION In conclusion, miR-877-5p inhibits epithelial mesenchymal transformation, cell proliferation, and invasion of BC cells via downregulating FGB.

Abstract
INTRODUCTION Loropetalum chinense var. rubrum blooms 2-3 times a year, among which the autumn flowering period has great potential for exploitation, but the number of flowers in the autumn flowering period is much smaller than that in the spring flowering period. METHODS Using 'Hei Zhenzhu' and 'Xiangnong Xiangyun' as experimental materials, the winter growth environment of L. chinense var. rubrum in Changsha, Hunan Province was simulated by setting a low temperature of 6-10°C in an artificial climate chamber to investigate the effect of winter low temperature on the flowering traits and related gene expression of L. chinense var. rubrum. RESULTS The results showed that after 45 days of low temperature culture and a subsequent period of 25°C greenhouse culture, flower buds and flowers started to appear on days 24 and 33 of 25°C greenhouse culture for 'Hei Zhenzhu', and flower buds and flowers started to appear on days 21 and 33 of 25°C greenhouse culture for 'Xiangnong Xiangyun'. The absolute growth rate of buds showed a 'Up-Down' pattern during the 7-28 days of low temperature culture; the chlorophyll fluorescence decay rate (Rfd) of both materials showed a 'Down-Up-Down' pattern during this period. The non-photochemical quenching coefficient (NPQ) showed the same trend as Rfd, and the photochemical quenching coefficient (QP) fluctuated above and below 0.05. The expression of AP1 and FT similar genes of L. chinense var. rubrum gradually increased after the beginning of low temperature culture, reaching the highest expression on day 14 and day 28, respectively, and the expression of both in the experimental group was higher than that in the control group. The expressions of FLC, SVP and TFL1 similar genes all decreased gradually with low temperature culture, among which the expressions of FLC similar genes and TFL1 similar genes in the experimental group were extremely significantly lower than those in the control group; in the experimental group, the expressions of GA3 similar genes were all extremely significantly higher than those in the control group, and the expressions all increased with the increase of low temperature culture time. DISCUSSION We found that the high expression of gibberellin genes may play an important role in the process of low temperature promotion of L. chinense var. rubrum flowering, and in the future, it may be possible to regulate L. chinense var. rubrum flowering by simply spraying exogenous gibberellin instead of the promotion effect of low temperature.

Abstract
Objective: To investigate the clinicopathological characteristics of H3K27-altered diffuse midline glioma (DMG), and to analyze DMG's prognostic factors, and subsequently, to study the possibility of using NTRK as a therapeutic target for DMG. Methods: A total of 232 DMG diagnosed at the Sanbo Brain Hospital, Capital Medical University, Beijing, China from July 2016 to March 2021 were collected. Their clinical, radiological and pathological features, the ratio of MGMT promoter methylation, expression of NTRK, and characteristics of NTRK gene fusion were analyzed. The prognostic values of different factors were also studied, including age, tumor location, histological grade, gene and protein expression of NTRK, and postoperative adjuvant therapy. Results: Among the 232 DMG cases, there were 8 patients with both primary and relapse tumors on the record. Thus, a total of 224 patients were analyzed, including 118 males and 106 females. There were 126 adults (>18 years of age) and 98 children (≤18 years of age). Notably, the most frequent location was thalamus (41/126, 32.5%) in adults, but brainstem (59/96, 60.2%) in children. The lesions showed T1 hypointensity or isointensity, and T2 hyperintensity. However, contrast enhancement patterns of the tumors varied, with many tumors lacking contrast-enhancing. The histological grades included grade 2 (9/224, 4.0%), grade 3 (41/224, 18.3%) and grade 4 (174/224, 77.7%). Two hundred and twenty-four DMGs were diffusely positive for H3K27M and negative for H3K27me3. The ratio of MGMT promoter methylation was low (1/45, 2.2%). One hundred and seventy-seven of the 224 cases (177/224, 79.0%) were positive for NTRK. Fifty cases were analyzed using fluorescence in situ hybridization. Among them, five DMGs (positive rate, 10.0%) were NTRK fusion positive. This study showed that there were no differences between adult and pediatric DMGs in histological grading, expression of NTRK, and NTRK gene fusion. One hundred and fifty-nine patients were included in the follow-up analysis (P>0.05). During the follow-up period, 109/159 patients (69.6%) died of the disease, with a median survival time of 12 months (range 1 to 55 months). Univariate log-rank analysis showed that age, location, surgical procedure and postoperative adjuvant therapy were associated with overall survivals of the DMG patients (P<0.05). Conclusions: The prognosis of DMG is poor overall. There are differences between adult and pediatric DMGs in anatomic location and prognosis, but not in other features. NTRK1 gene fusion is detected in 10.0% of the tumors. It suggests that TRK inhibitor might be a choice for treating DMG.

Abstract
Objective: To examine the purchase behaviors of prepackaged food and its determinants among primary and middle school students in 6 provinces of China. Methods: A multi-stage sampling strategy was adopted to select 2 499 primary and middle school students and their parents from the eastern region of China(Beijing, Jiangsu Province, Guangdong Province), the northeast region(Heilongjiang Province), the central region(Henan Province) and the western region(Sichuan Province) from July 2020 to March 2021. Socio-demographic characteristics of students and their parents, eating-related behaviors and the purchase behaviors of prepackaged food of students, and parents' attitudes towards students' eating behavior were collected through questionnaire towards students and their parents. The χ² test was conducted to compare the purchase behaviors in different groups of students, and multivariate logistic stepwise regression analysis was used to analyze the determinants among primary and middle school students. Results: The age of 2 499 participants was(12.7±2.5) years. There were 1 272(50.9%) females and 1 279(51.2%) middle school students. About 1 404(56.2%) students bought prepackaged food. The top 6 prepackaged foods bought at least once a week were milk and dairy products(74.6%), baked food(58.7%), beverages(42.8%), puffed food(40.8%), chocolate and candy(39.8%), and nuts and dried fruits(37.5%). The multivariate logistic regression model analysis results showed that compared with primary school students, rural students, non-boarding students, students who did not like snacks and students whose parents paid attention to their children eating snacks, middle school students(OR=3.36, 95%CI:2.73-4.12), urban students(OR=1.33, 95%CI:1.11-1.61), boarding students(OR=2.15, 95%CI:1.66-2.79), students who liked snacks(OR=2.01, 95%CI:1.66-2.43), students whose parents did not pay attention to their children eating snacks(OR=1.27, 95%CI:1.05-1.54) were more likely to buy prepackaged food by themselves. Compared with students whose parents had education level of junior high school and below, students whose parents had education level of undergraduate and above(OR=0.70, 95%CI:0.53-0.92) were less likely to buy prepackaged food by themselves. Compared with students whose family monthly income was less than 5 000 yuan, students whose family monthly income was over 10 000 yuan(OR=0.67, 95%CI:0.52-0.87) were less likely to buy prepackaged food by themselves. Conclusion: Many primary and middle school students buy prepackaged food by themselves in 6 provinces of China. Individual characteristics such as grade, place of residence, boarding status, as well as family environment such as parents' education level, monthly income and concern about children eating snacks are the influencing factors of purchasing prepackaged food.

Abstract
Objective: To explore the association between the cognition of Nutrition Facts Panel and prepackaged food purchase behavior among residents in six provinces in China. Methods: Using a multi-stage sampling method, 3 002 adults aged 18-70 were selected from the western region (Sichuan), eastern region (Guangdong, Jiangsu, Beijing), central region (Henan), and northeastern region (Heilongjiang) of China from July 2020 to March 2021. Socio-demographic characteristics of participants and their cognition of Nutrition Facts Panel and prepackaged food purchase behavior were collected through questionnaire. A multivariate binary logistic regression model was used to analyze the association between cognition of Nutrition Facts Panel and prepackaged food purchase behavior. Results: The age of 3 002 subjects was (42.3±13.4) years, among which 63.8% (1 914) were female, 66.7% knew the Nutrition Facts Panel, 49.8% would read it when purchasing, 30.7% could understand it, and 56.6% (1 699) bought prepackaged food more than once a week. The results of multivariate analysis showed that after adjusting for relevant confounding factors, compared with the participants knowing but not reading the Nutrition Facts Panel, the group knowing and reading was more likely to buy 11 types of prepackaged food at least once a week (all P<0.05). Compared with the participants reading but not understanding the Nutrition Facts Panel, the group reading and understanding was less likely to buy 11 types of prepackaged food at least once a week (all P<0.05). Conclusion: There was a correlation between cognition of Nutrition Facts Panel and prepackaged food purchase behavior among residents.

Abstract
In this study a quantitative 31P nuclear magnetic resonance (31P NMR) spectroscopy method was described to determine positional isomeric impurity β-GPC in commercial products of L-α-GPC. The samples were dissolved in D2O and trimethyl phosphate (TMP) was selected as an internal calibrant. The measurements were performed on a Bruker 500 MHz spectrometer and the spectra were recorded under optimized process conditions. A good linear relationship was constructed for β-GPC in the range of 62.7-528.0 µg·mL-1, i.e. 0.03-0.25 % (w/w %, in relative to L-α-GPC) with a correlative coefficient of 0.9996. The limit of quantification (LOQ) and limit of detection (LOD) were 62.7 µg·mL-1 and 20.9 µg·mL-1 with signal to noise of 3 and 10, respectively. The spiked recoveries were in the range of 98.17-99.78 % with the relative standard deviation (RSD %) less than 1.0 %. Therefore, it could be supposed that the 31P NMR was a promising alternative method for sensitive determination of β-GPC for strict quality control of L-α-GPC.

Abstract
In this study a kinetic and thermodynamic atropisomeric transformation due to a hindered rotation around the tetrahydroisoquinoline-based amide group was investigated. Quantum chemistry calculations were applied to investigate the transformation under the gas phase and several solvents with different polarity, and then evaluated by dynamic HPLC determination. It was found that the transformation rate of constants and the half-life time varied under the influence of solvent polarity and temperature and the energies of rotational barrier were determined ranging between 87 and 92 kJ∙mol-1. A primary binding study with HSA confirmed a rapid interconversion under the simulated physiological conditions. It is therefore suggested to take this atropisomeric compound as a racemic mixture for its future drug development.

Abstract
Objective: To investigate the preference for Front-of-Pack Labeling (FOP) and its association with the understanding of the Nutrition Facts Panel among Chinese residents. Methods: A multi-stage sampling strategy was adopted to select 3 002 people aged between 18 and 70 years old from the eastern region of China (Beijing, Jiangsu Province, Guangdong Province), the northeast region (Heilongjiang Province), the central region (Henan Province) and the western region (Sichuan Province) from July 2020 to March 2021. Socio-demographic characteristics of participants and their understanding of the Nutrition Facts Panel and preference for FOP were collected. The χ² test was conducted to compare the preference for FOP in different groups of population, and multivariate logistic regression was used to analyze the association between the preference for FOP and the understanding of the Nutrition Facts Panel. Results: The mean age of 3 002 participants was (42.3±13.4) years, of which 1 914 (63.8%) were females and 69.3% could not understand the Nutrition Facts Panel. About 2 458 respondents (81.9%) suggested that FOP could be promoted. The top three nutrients that should be labeled were sugar (68.4%), salt (68.2%) and total fat (62.4%). The number of participants who believed that the Multiple Traffic Lights (MTL) could be easier to help consumers to quickly choose healthy food, attract attention and provide the most needed information was 1 064 (35.4%), 1 026 (34.2%) and 1 140 (38.0%), respectively. The multivariate logistic regression analysis showed that, compared with the Guideline Daily Amount (GDA) system, participants who could not understand the Nutrition Facts Panel preferred (1) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could quickly help you choose food more easily?"[OR (95%CI): 2.21 (1.62-3.02), 1.64 (1.22-2.22), 1.79 (1.31-2.45), respectively]; (2) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could attract your attention the most?"[OR (95%CI): 2.62 (1.92-3.59), 1.96 (1.45-2.66), 2.25 (1.66-3.04), respectively]; and (3) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could provide you with the most needed information?"[OR (95%CI): 2.33 (1.70-3.21), 2.21 (1.66-2.95), 2.01 (1.50-2.71), respectively]. Conclusion: The residents from six provinces in China have a supportive attitude towards FOP. The interpretive FOP with color information, specific nutrient information and summary indicator can be launched. The nutrition information of sugar, salt and total fat could be prioritized to be labeled on the FOP.

Abstract
Objective: To investigate the imaging features of condylar cystic degeneration of temporomandibular joint (TMJ) by cone-beam CT (CBCT), spiral CT, MRI and radionuclide bone imaging. Methods: From January 2018 to December 2020, thirty-two patients with cyst-like lesions of condylein temporomandibular joint were examined by CBCT, spiral CT, MRI and radionuclide bone imaging at the Department of Oral and Maxillofacial Surgery in General Hospital of Chinese PLA. There were 12 males and 20 females involved, aged from 16 to 65 years with an average age of (33.9±12.5) years. The characteristics of CBCT, spiral CT, MRI and radionuclide bone imaging were analyzed. Condylar cyst like lesions were classified as type A and type B based on the presence or absence of surface bone defects. Condylar cyst like lesions were classified as type Ⅰ(yes) and type Ⅱ(no) according to the accompanying bone marrow edema-like lesions of the condyles. The incidence of condylar bone marrow edema, disc displacement and abnormal bone metabolism were analyzed. Results: A total of 64 joint images of 32 patients were included, including 34 sides with TMJ cyst-like lesion and 6 sides with multiple cyst-like lesions,the total cyst-like lesions were 42. The largest diameter of cyst-like lesion ranged from 1.0 to 12.4 mm, with an average length of (3.7± 1.8) mm. There were 24 cases of type A TMJ cyst like lesion and 10 cases of type B cyst-like lesion. The detection rate of CBCT was 95.2% (40/42) and that of spiral CT was 100% (42/42), there was no significant difference (Calibration Chi-square=0.51, P=0.474). The detection rate of nuclear magnetic resonance was 80.1% (34/42), and the detection rate of cyst-like lesions less than 2 mm was 3/11. In the cyst like lesion side, there were 9 sides with anterior disc displacement with reduction, 20 sides with anterior disc displacement without reduction.

Abstract
Peripheral nerve injuries are mainly related to severe trauma, fracture and tumor surgery, leading to reduced quality of life and impaired physical and mental health. The repair of peripheral nerve still faces great challenges in clinic, and the research on the regeneration and repair of peripheral nerve has become a hot issue in related disciplines. Cell therapy plays an irreplaceable role in tissue regeneration and repair. Schwann cells are ideal cells for peripheral nerve repair, but their limited sources inhibit the clinical application. Dental pulp stem cells are derived from neural crest, which provides a new cell source for nerve regeneration. The purpose of this article is to review the research progress of dental pulp stem cells for peripheral nerve repair.

Abstract
Objective: To investigate the imaging features of condylar cystic degeneration of temporomandibular joint (TMJ) by cone-beam CT (CBCT), spiral CT, MRI and radionuclide bone imaging. Methods: From January 2018 to December 2020, thirty-two patients with cyst-like lesions of condylein temporomandibular joint were examined by CBCT, spiral CT, MRI and radionuclide bone imaging at the Department of Oral and Maxillofacial Surgery in General Hospital of Chinese PLA. There were 12 males and 20 females involved, aged from 16 to 65 years with an average age of (33.9±12.5) years. The characteristics of CBCT, spiral CT, MRI and radionuclide bone imaging were analyzed. Condylar cyst like lesions were classified as type A and type B based on the presence or absence of surface bone defects. Condylar cyst like lesions were classified as type Ⅰ(yes) and type Ⅱ(no) according to the accompanying bone marrow edema-like lesions of the condyles. The incidence of condylar bone marrow edema, disc displacement and abnormal bone metabolism were analyzed. Results: A total of 64 joint images of 32 patients were included, including 34 sides with TMJ cyst-like lesion and 6 sides with multiple cyst-like lesions,the total cyst-like lesions were 42. The largest diameter of cyst-like lesion ranged from 1.0 to 12.4 mm, with an average length of (3.7±1.8) mm. There were 24 cases of type A TMJ cyst like lesion and 10 cases of type B cyst-like lesion. The detection rate of CBCT was 95.2% (40/42) and that of spiral CT was 100% (42/42), there was no significant difference (Calibration Chi-square=0.51, P=0.474). The detection rate of nuclear magnetic resonance was 80.1% (34/42), and the detection rate of cyst-like lesions less than 2 mm was 3/11. In the cyst like lesion side, there were 9 sides with anterior disc displacement with reduction, 20 sides with anterior disc displacement without reduction. In the non-cyst like lesion side, 10 sides with anterior disc displacement with reduction and 6 sides with anterior disc displacement without reduction. There was a significant difference in the displacement of the disc between cyst-like and non-cystic lesion side (χ²=7.80, P=0.005). MRI showed that 6 cases of cystic side[17.6% (6/34)] had bone marrow edema-like lesions (all type A), 1 case of non-cyst like lesions side [3.3% (1/30)]had bone marrow edema-like lesion, there was no significant difference between cystic and non-cystic lesions (Calibration Chi-square=2.04, P=0.153).

Radionuclide bone imaging showed abnormal bone metabolism in 26 patients in the cyst-like lesion side and 5 patients in the non-cyst like lesion side (χ²=22.82, P<0.001). Conclusions Multi-slice Spiral CT could detect the cyst-like lesion of TMJ condyle in the early stage, which is different from the large joint. And the formation mechanism may vary from the different classifications.

Abstract
Objective: To investigate the clinicopathological characteristics and differential diagnosis of pediatric SMARCB1/INI1-deficient poorly differentiated chordoma (PDC) of the skull base. Methods: Five cases of SMARCB1/INI1-deficient PDC were identified in 139 cases of chordoma diagnosed in Sanbo Brain Institute, Capital Medical University, Beijing, China from March 2017 to March 2021. The clinical and imaging data of the 5 PDCs were collected. H&E and immunohistochemical staining, and DNA methylation array were used, and the relevant literatures were reviewed. Results: All 5 PDCs were located at the clivus. The average age of the patients was 6.4 years, ranging from 3 to 16 years. Three patients were female and two were male. Morphologically, in contrast with classical chordomas, they presented as epithelioid or spindle tumor cells organized in sheets or nests, with necrosis, active mitoses, and infiltration into surrounding tissue. All cases showed positivity of CKpan, EMA, vimentin and brachyury (nuclear stain), and loss of nuclear SMARCB1/INI1 expression. S-100 protein expression was not frequent (2/5). Ki-67 proliferative index was high (20%-50%). All cases had over-expressed p53. It was necessary to differentiate SMARCB1/INI1-dificient PDC from SMARCB1/INI1-dificient tumors occurring at skull base of children or the tumors with epithelial and spindle cell morphological features. The 3 PDCs with DNA methylation testing showed the methylation profiles different from the pediatric atypical teratoid/rhabdoid tumors. They formed an independent methylation profile cluster. The clinical prognosis of the 5 patients was poor, and the overall survival time was 2-17 months. Conclusions: PDC is a special subtype of chordoma, which often affects children and occurs in the clivus. The PDC shares epithelioid or spindle cell morphologic features which are different from the classic chordoma. Besides the typical immunohistochemical profile of chordoma, PDC also has loss of nuclear SMARCB1/INI1 expression and distinct epigenetic characteristics.

Abstract
Objective: To explore the application of three-dimensional (3D) printing technology in oral and maxillofacial surgery, so as to optimize and standardize its design and application. Methods: From January 2010 to December 2020, 40 cases of mandibular tumor surgery (20 cases of conventional group and 20 cases of guide plate group), 20 cases of temporomandibular joint replacement surgery (10 cases of conventional group and 10 cases of guide plate group), 20 cases of malocclusion surgery (10 cases of conventional group and 10 cases of guide plate group), 20 cases of radioactive particle implantation surgery (10 cases of CT guided group and 10 cases of guide plate group) were analyzed. All patients in the guide plate group were scanned with spiral CT, and the 3D models of the jaw and the donor bone area were reconstruction. According to the purpose of surgical guide, the design and clinical application of osteotomy guide, in place forming guide and puncture positioning guide were analyzed respectively. The design time of guide plate, the performance and printing time of guide material, the sterilization method of guide and its influence on accuracy, and the influence of guide application on operation time and accuracy were analyzed. Results: The design time of orthognathic guide plate was (2.9±1.8) d, and the design time of mandibular transplantation guide plate was (2.8±1.8) d, that of the temporomandibular joint replacement guide plate and the puncture guide plate was (2.2±0.3) and (0.9±0.3) d. The average printing time of the 40 maxilla model was (11.1±1.6) h, and that of the 40 mandible models was (2.6±0.4) h. The average printing time of the 40 sets of osteotomy and positioning guide plate was (2.5±0.8) h, and that of the 10 puncture positioning guide plate (1.1±0.4) h. The operation time of the conventional group was (6.99±1.10) and (6.02±0.55) h. In the CT guided group, the operation time was (1.91±0.55) h and (0.89±0.15). The operation time of mandible tumor operation and radioactive particle implantation in the guide plate group was less than that in the control group (P<0.05), and there was no significant difference in the operation time of orthognathic surgery and joint replacement between the two groups (P>0.05). The displacement distance of the mark points in the TMJ replacement and mandibular tumor operation guide group was less than that in the control group (P<0.05), and the error of the guide plate in orthognathic operation and particle implantation operation was basically less than 1 mm. Conclusions: The application of the surgical guide plate made by 3D printing technology helps to complete the operation more safely, accurately and quickly, But its design, manufacture and disinfection still need to be further standardized and improved.

Abstract
Temporomandibular joint (TMJ) is a unique synovial joint in mammals. There have been many reports on the structure and function of TMJ during embryonic development.Although studies on TMJ related signal molecules and transcription factors during embryonic development have been carried out since the last century, there are few reports on the molecular genetic regulation of TMJ compared with the abundant molecular regulation information of synovial joint. The studies on signal molecules and transcription factors of TMJ embryonic development were mainly conducted in rodents.There were few studies on the regulatory molecules and their regulatory mechanisms related to the development of TMJ conducted in large mammals and human embryos. This article reviews the research progress of key signal molecules and transcription factors of TMJ in embryonic development on the basis of modern molecular biology technology in order to find more core regulatory molecules and understand their regulation mechanism on TMJ development.

Abstract
OBJECTIVE To explore the potential factors that affect the accuracy of endoscopic diagnosis for Japan narrow-band imaging (NBI) Expert Team (JNET) type 2B colorectal lesions. OBJECTIVE The clinical data were collected from 261 patients with JNET type 2B colorectal lesions diagnosed in Nanfang Hospital between July, 2018 and July, 2021. We analyzed the macroscopic type, size, location or pit pattern classification of the lesions for their potential influence of the diagnostic accuracy of JNET type 2B lesions. OBJECTIVE The 261 lesions included 91 low-grade intramucosal neoplasia lesions (34.9%), 132 high-grade intramucosal neoplasia lesions (50.6%), 13 submucosal invasive cancer lesions (5.0%), and 25 deep submucosal invasive cancer lesions (9.6%). The coincidence rate between endoscopic prediction and pathological diagnosis of these lesions was 55.6% (145/ 261). The macroscopic type and size of the lesions were significantly associated with the diagnostic accuracy of JNET type 2B lesions (P < 0.001). There was a significant difference in the diagnostic accuracy among the lesions with different pit pattern types (P < 0.001). OBJECTIVE Both the macroscopic type and size affect the accuracy of endoscopic diagnosis of JNET type 2B colorectal lesions. JNET classification combined with pit pattern types can have better accuracy in predicting the pathological diagnosis of these lesions.

Abstract
Background:To facilitate earlier diagnosis of spondyloarthritis (SpA), we have previously cross-culturally adapted a self-administered screening questionnaire.Objectives:We aimed to improve the sensitivity of this questionnaire as a screening tool by comparing various scoring methods.Methods:Subjects newly referred to a rheumatology clinic self-administered the questionnaire before seeing a rheumatologist. Identification of axial SpA by the questionnaire using original scoring (Method A) and scoring based on Assessment of SpondyloArthritis International Society (ASAS) inflammatory back pain (IBP) criteria (Method B), ASAS referral criteria (Method C), ASAS classification criteria (Method D) and a combination of ASAS referral and classification criteria (Method E) were compared to classification by the ASAS classification criteria and diagnosis by rheumatologist. Since Methods B-E were based on SpA features, we compared self-reported vs rheumatologist-documented features in subjects with axial SpA.Results:Of 1418 subjects (age: 54 ± 14 years, female: 73%), 39 were classified as axial SpA cases by classification criteria. Methods A-E yielded sensitivities of 39%, 72%, 67%, 49% and 85%, respectively, among patients newly referred to the rheumatology clinic (Table 1). Rheumatologist-documented clinical SpA features exceeded self-report for IBP (62 vs 44%) and uveitis (15 vs 5%). The reverse was true for arthritis (21 vs 80%), enthesitis (28 vs 33%), dactylitis (3 vs 18%), good response to NSAIDs (33 vs 41%) and family history for SpA (5 vs 10%).Table 1.Performance of the five scoring methods for the cross-culturally adapted Hamilton axial SpA questionnaire.Scoring methodSensitivity(95% confidence interval)Specificity(95% confidence interval)Positive predictive value(95% confidence interval)Negative predictive value(95% confidence interval)Method A38.5(23.4 – 55.4)93.7(92.3 – 94.9)14.7(8.5 – 23.1)98.2(97.3 – 98.8)Method B71.8(55.1 – 85.0)73.1(70.7 – 75.4)7.0(4.7 – 10.0)98.9(98.1 – 99.5)Method C66.7(49.8 – 80.9)77.8(75.5 – 80.0)7.8(5.2 – 11.3)98.8(98.0 – 99.4)Method D48.7(32.4 – 65.2)74.9(72.5 – 77.2)5.2(3.2 – 8.0)98.1(97.1 – 98.8)Method E84.6(69.5 – 94.1)37.2(34.6 – 39.8)3.7(2.5 – 5.1)98.8(97.5 – 99.6)Method A: the original scoring defined by the questionnaire developers; Method B: a scoring based on the ASAS IBP criteria; Method C: a scoring based on the ASAS referral criteria; Method D: a scoring based on the ASAS classification criteria for axial and peripheral SpA; Method E: a scoring based on a combination of the ASAS referral and classification criteria.Conclusion:A self-administered questionnaire scored based on a combination of ASAS referral and classification criteria achieved high sensitivity in identifying axial SpA in subjects referred to a rheumatology clinic. This supports its evaluation as a screening tool for axial SpA in the general population.References:[1]Xiang L, Teo EPS, Low AHL, Leung YY, Fong W, Xin X, et al.

Abstract
Background:The interval between symptom onset and diagnosis can often be longer than is ideal in autoimmune rheumatic diseases (ARDs).Objectives:We aimed to characterise this interval among patients newly diagnosed with ARDs in a multi-ethnic Asian population and to identify factors associated with a longer interval.Methods:We used Scott’s model of pathways to treatment to characterise the interval between symptom onset and diagnosis into 4 intervals: #1 between symptom onset and first seeking medical attention, #2 between first medical attention and rheumatology referral, #3 between rheumatology referral and first rheumatology assessment, and #4 between first rheumatology assessment and diagnosis. Linear regression models were used to identify factors associated with a longer the overall interval between symptom onset and diagnosis and Interval #1.Results:Among 259 patients (age: 51±15 years, female: 71%, most common three ARDs: rheumatoid arthritis (n = 75), axial spondyloarthritis (n = 40) and psoriatic arthritis (n = 35)), the median overall interval was 11.5 months. Interval #1 (median = 4.9 months) was significantly longer than the other intervals (Table 1). Patients with axial spondyloarthritis had a significantly longer overall interval (median = 38.7 months) and Interval #1 (median = 26.6 months) compared to patients with RA (median = 7.6 and 3.5 months, respectively), PsA (median = 7.0 and 2.6 months, respectively) and the other ARDs. Gender was the only patient-related factor significantly associated with the overall interval (reference = male, coefficient = -15.3, p = 0.033) in regression models.Conclusion:A longer than ideal interval between symptom onset and diagnosis was observed among patients with ARDs. This was primarily due to a relatively long interval between symptom onset and first seeking medical attention, and highlights the importance of interventions targeting patients prior to first medical attention in reducing the duration between symptom onset and diagnosis.References:[1]Scott SE, Walter FM, Webster A, Sutton S, Emery J.

Abstract
Anaphylaxis is increasingly in children. Foods are the most common triggers. Anaphylaxis is currently undernotified, underdiagnosed, and undertreated in China. Recurrence of anaphylaxis has been recorded in one-third of cases, thus it is essential to prevent recurrence in long-term personalized management of anaphylaxis. Here it reviews the avoidance of triggers and cofactors/risk factors,long-term management of anaphylaxis. This article aims to increase awareness of anaphylaxis in children in order to improve management and prevention of recurrences.

Abstract
BACKGROUND Mutation in Odontogenesis-associated phosphoprotein (ODAPH) has been reported to cause recessive hypomineralized amelogenesis imperfecta (AI) in human. However, the exact role of ODAPH in amelogenesis is still unknown. RESULTS ODAPH was identified as a novel constituent of the atypical basal lamina located at the interface between maturation ameloblasts and the enamel by dual immunofluorescence staining of ODAPH and LAMC2. Odaph knockout mice were generated to explore the function of ODAPH in amelogenesis. Odaph-/- mice teeth showed severely attrition and reduced enamel mineralization. Histological analysis showed from transition or early-maturation stage, ameloblasts were rapidly shortened, lost cell polarity, and exhibited cell pathology. Abundant enamel matrix marked by amelogenin was retained. Temporary cyst-like structures were formed between flattened epithelial cells and the enamel from maturation stage to eruption. The integrity of the atypical basal lamina was impaired indicated by the reduced diffuse expression of LAMC2 and AMTN. The expression of maturation stage related genes of Amtn, Klk4, Integrinβ6 and Slc24a4 were significantly decreased. CONCLUSIONS Our results suggested Odaph played vital roles during amelogenesis by maintaining the integrity of the atypical basal lamina in maturation stage, which may contribute to a better understanding of the pathophysiology of human AI.

Abstract
Down-regulated miR-223-3p was found in rheumatoid arthritis. This study aimed to further explore the level and role of miR-223-3p in gout arthritis (GA). After monosodium urate (MSU)-induced GA rat and fibroblast-like synoviocytes (FLSs) models were established, the rat paw volume and gait score were documented and the FLSs were transfected with miR-223-3p mimic/inhibitor or NLR family pyrin domain containing 3 (NLRP3) over-expression plasmids. The MiR-223-3p target was found through bioinformatics and the dual-luciferase reporter. The rat joint pathological damage was observed by hematoxylin and eosin staining. The levels of interleukin (IL)-1β, tumor necrosis factor (TNF)-α and articular elastase in rats were detected by enzyme-linked immunosorbent assay (ELISA). The viability and pyroptosis of FLSs were detected by methyl thiazolyl tetrazolium (MTT) and flow cytometry. The expressions of miR-223-3p, NLRP3, cleaved caspase-1, IL-1β, apoptosis-associated speck-like protein (AS) and cleaved N-terminal gasdermin D (GSDMD) in FLSs or rat synovial tissues were detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR), immunofluorescence, Western blot or immunohistochemistry analysis. MSU increased the paw volume, gait score, inflammation in synovial tissues and increased the levels of IL-1β, TNF-α and articular elastase in rats. MSU decreased the viability and increased the pyroptosis of FLSs, up-regulated the expression of NLRP3, ASC, cleaved caspase-1, cleaved N-terminal GSDM, and IL-1β, and down-regulated miR-223-3p expression in synovial tissues of rat joints and FLSs. MiR-223-3p mimic reversed the effect of MSU on lowering cell viability, increasing pyroptosis in FLSs, while miR-223-3p inhibitor further enhanced the effect of MSU on FLSs. NLRP3 was a target of miR-223-3p. Also, NLRP3 over-expression reversed the effects of miR-223-3p on MSU-induced FLSs. MiR-223-3p inhibited pyroptosis in MSU-induced rats and FLSs by targeting NLRP3.

Abstract
Objective: To understand the research progress and quality of lung cancer screening guidelines and consensus in China and abroad, and to provide reference for the formulation of high-quality lung cancer screening guidelines in China. Methods: Databases including PubMed, Medline, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, SinoMed, VIP and Wanfang Data were searched, websites and important references were also searched by hand retrieval. The Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ) and Reporting Items for Practice Guidelines in Healthcare (RIGHT) were used to assess the quality of newly published or updated guidelines and consensus. Results: A total of 9 guidelines and consensus published between 2015 and 2020 were included in this study, with countries including the United States, China, Canada, Saudi Arabia and South Africa. The field of scope and purpose and clarity of presentation scored relatively high but the rigor of development and applicability scored low. Five guidelines were judged to be A-level, all of which were published abroad, and the remaining four were B-level, including three guidelines and consensus issued by China and 1 guideline issued by South Africa. The report rate of RIGHT were higher in basic information and background, lower in review and quality assurance, funding and declaration and management of interests. There were 5 guidelines with a good level and 4 guidelines and consensus with a moderate level. The best overall quality guidelines were those published by the American College of Chest Physicians in 2018 and by the Canadian Task Force on Preventive Health Care in 2016. Conclusions: The number of countries and institutions that issue lung cancer screening guidelines and consensus had been increasing gradually, but the quality in China remained low. It is necessary to develop high-quality lung cancer screening guidelines suitable for China's national conditions in combination with evidence-based methods to guide practice.

Abstract
Background For stage II colon cancer, understanding of high-risk factors (HRFs) that affect the overall survival (OS) and the benefit of chemotherapy is limited. Meanwhile, no stable predictor can effectively predict OS of stage II colon cancer to date. Our study is aimed to identify HRFs associated with OS of stage II colon cancer, to quantify the risk conferred by each HRF, and to evaluate OS benefit gained by chemotherapy. Meanwhile, we attempt to establish a nomogram model for stage II colon cancer. Methods The clinical variables of patients with stage II colon cancer between 2000 and 2018 were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate analysis were performed to filtered out all the HRFs. We calculated the hazard ratios (HR) and evaluated the survival benefit of adjuvant chemotherapy for each HRF and combinations of HRFs. Then, a nomogram model based on all HRFs was established and verified. Results A total of 39,103 patients with stage II colon cancer were included. T4b tumors were the highest risk for reduced OS [HR =2.821; 95% confidence interval (CI): 1.949–4.082], mucin-producing tumors (HR =2.412; 95% CI: 1.326–4.388) the second, and lymph node (LN) examined less than 12 (HR =2.200; 95% CI: 1.786–2.710) the third. T4 tumors (HR =0.790; 95% CI: 0.542–1.151), poorly/undifferentiated tumors (HR =0.468; 95% CI: 0.237–0.924), and some combinations of HRFs containing either could benefit from adjuvant chemotherapy. Meanwhile, we established an effective nomogram model based on the identified HRFs. Conclusions The study has identified several novel HRFs for stage II colon cancer. Adjuvant chemotherapy has considerable OS benefit for stage II colon cancers with some specific HRFs, and treatment plans need to be individualized. Type and number of HRFs should be taken into consideration when recommending adjuvant chemotherapy. Our new nomogram model has better predictive ability and stability than the tumor-node-metastasis (TNM) stage system of American Joint Committee on Cancer (AJCC) staging system.

Abstract
Generally, impaired bones heal by bone repair and bone regeneration. These two processes are necessary during the healing period of dental implant. Vasculature plays a crucial role in bone healing because bones are highly vascularized tissue. Osteogenesis and angiogenesis are highly coupled processes and can be regulated by Hippo-YAP signaling pathway. Recent studies have demonstrated Hippo-YAP pathway may be regulated by alpha calcitonin gene-related peptide. However, the regulatory effects of αCGRP-YAP pathway on angiogenesis and osteogenesis during bone healing around implants remain unclear. Four groups of mice were established: KO Group: αCGRP -/- mice; KO + αCGRP group: αCGRP -/- mice with αCGRP overexpressing lentiviral transfection; KO + YAP group: αCGRP -/- mice with YAP overexpressing lentiviral transfection; WT group: wildtype mice. After 14 or 28 days, animals were sacrificed and tested. Results showed αCGRP deficiency hampered osteogenesis and angiogenesis. In addition, the impaired bone healing can be rescued by overexpressing αCGRP and YAP in αCGRP -/- mice. In-vivo results indicate αCGRP-YAP pathway promotes angiogenesis and osteogenesis in bone healing, especially at the early stage. Taken together, present study demonstrated αCGRP up-regulate the expression of YAP, and down-stream genes to promote the osteogenesis and angiogenesis around the implants.

Abstract
Growing evidence shows that a homozygous 6·7-kb deletion of the novel anti-inflammatory molecule leukocyte immunoglobulin-like receptor A3 (LILRA3) is associated with many autoimmune disorders. However, its effects on pathogenesis of inflammatory bowel disease (IBD) have yet not been clarified. LILRA3 is mainly expressed in monocytes, whereas its effects on biological behaviors of monocytes have not been systematically reported. In our study, to investigate the association between LILRA3 polymorphism and IBD susceptibility, LILRA3 polymorphism was assessed in 378 IBD patients and 509 healthy controls. Quantitative real time PCR (qRT-PCR), Western blot and immunohistochemistry (IHC) were employed to detect the LILRA3 expression in IBD patient blood and intestinal samples. The human U937 monocyte cell line was employed to establish LILRA3 over-expressing cells and the effects of LILRA3 on the biological behaviors of U937 cells were systematically explored. Although no association of the polymorphism with IBD development was found, LILRA3 expression was markedly increased in IBD patients compared with healthy controls. Over-expression of LILRA3 in monocytes led to significant decreases in secretion of interferon (IFN)-γ, tumor necrosis factor (TNF)-α and interleukin (IL)-6. Additionally, LILRA3 abated monocyte migration by reducing the expression of several chemokines and enhanced monocyte phagocytosis by increasing CD36 expression. Furthermore, LILRA3 promoted monocyte proliferation through a combination of Akt and extracellular receptor kinase/mitogen-activated protein kinase (Erk/MEK) signaling pathways. We report for the first time, to our knowledge, that LILRA3 is related to IBD and functions as an anti-inflammatory modulator in U937 cells.
