Abstract
Background Androgenetic alopecia (AGA) is the most common type of androgen-associated hair loss. Previous studies have indicated an association between the gut microbiota and AGA. To delve deeper, we executed a two-sample Mendelian randomization (MR) analysis to investigate the potential causal relationship between the gut microbiota and AGA. Methods A two-sample MR investigation was utilized to delve into the intricate interplay between gut microbiota and AGA. Information regarding 211 gut microbial taxa was sourced from the MiBioGen consortium. The summary statistics of the genome-wide association studies (GWAS) for AGA were obtained from the FinnGen biobank, which included 195 cases and 201,019 controls. Various analytical approaches, including Inverse Variance Weighting (IVW), Weighted Median, MR-Egger, Weighted Mode, and Simple Mode were employed to evaluate the causal impact of gut microbiota on AGA. Sensitivity analyses were subsequently conducted to affirm the robustness of the findings. Results A two-sample MR investigation unveiled the genus Olsenella, genus Ruminococcaceae UCG-004, and genus Ruminococcaceae UCG-010 were identified as risk factors associated with AGA. In contrast, the family Acidaminococcaceae and genus Anaerofilum, along with the genus Ruminiclostridium 9, demonstrated a protective effect. The sensitivity analyses provided additional assurance that the findings of the current study were less susceptible to the influence of confounding variables and biases. Conclusion The MR study has established a link between specific gut microbiota and AGA, offering evidence for the identification of more precisely targeted probiotics. This discovery has the potential to aid in the prevention, control, and reversal of AGA progression.

Abstract
PURPOSE/OBJECTIVE(S) The present study aimed to evaluate surface dose and skin toxicity in breast cancer after breast-conserving surgery with five treatment modalities: flattening filter mode of intensity modulated radiation therapy (IMRT-FF,6MV), flattening filter-free mode of intensity modulated radiation therapy (IMRT-FFF,6MV), direct mode of TOMO (TOMO-direct, FFF, 6MV), helical mode of TOMO (TOMO-helical, FFF, 6MV), intensity modulated proton therapy (IMPT, spot scanning). MATERIALS/METHODS Ten patients with breast cancer treated at our institution after breast-conserving surgery were randomly selected for this study. Five plans were designed for each patient with the same target coverage and the prescription of 50Gy/25f, IMRT-6FF, IMRT-6FFF, TOMO-direct, TOMO-helical, and IMPT. Based on CT datasets, IMRT-6FFF, TOMO-direct, TOMO-helical, and IMPT were compared to IMRT-6FF with skin dose and skin toxicity. Among the five plannings, the angles of the IMRT-6FF vs. IMRT-6FFF and TOMO-direct were the same. We extracted the relative complement in the Body of its 3Derosion defined by a spherical structuring element of radius r = 3 mm and r = 5mm (skin3 and skin5). To calculate the relative Dose-surface histograms (DSH), we used the surface of patients receiving at least 5Gy to delimit the breast region's skin area and normalize the absolute DSH. Skin dose were assessed with V5Gy, V10Gy, V15Gy, V20Gy, V25Gy, V30Gy, V40Gy, V45Gy, V50Gy of the structure of skin3 and skin5. The published NTCP LKB (normal tissue complication probability, Lyman-Kutcher-Burman) model (TD50 = 39 Gy,m = 0.14,n = 0.38) was employed to evaluate severe acute radiation-induced skin toxicity. RESULTS There was no statistically significant difference between the structure of skin3 and skin5 between IMRT-6FF and IMRT-6FFF. For the same PTV coverage, the TOMO-helical plans had significantly higher surface dose in terms of V5Gy, V10Gy, and V15Gy than the IMRT plans (p <0.005). For structure of skin3, mean V30Gy, V35Gy, V40Gy, V45Gy, V50Gy were (64.0%,65.8%,79.0%,70.0%,64.6%), (51.3%,55.4%,74.3%,61.7%,59.5%), (32.4%,36.6%,65.2%,53.0%,53.0%), (13.7%,14.1%,45.8%,35.7%,37.6%), (1.6%/0.8%/12.2%,6.6%,1.0%). For the structure of skin5, mean V30Gy, V35Gy, V40Gy, V45Gy, V50Gy were (66.1%,67.1%,76.4%,68.6%,62.6%), (57.9%,60.4%,72.3%,61.2%,57.7%), (45.5%,48.4%,65.2%,53.9%,51.8%), (28.4%,30.8%,51.2%,42.0%,40.0%), (6.8%,6.3%,22.6%,17.9%,8.0%).Compared to IMRT-6FF, TOMO-direct and TOMO-helical had higher surface dose(p<0.05). For IMRT-6FF/IMRT-6FFF/TOMO-direct/TOMO-helical/IMPT, the mean ratio of severe acute radiational skin toxicity were14.7%,17.1%,46.3%,29.4%, and 24.1%. CONCLUSION For TOMO-direct and TOMO-helical planning, the skin dose and toxicity ratio were higher than IMRT-6FF. Compared to IMRT-6FF, V45Gy of skin3 and V40Gy of skin5 of IMPT were higher than IMRT-6FF, while the skin toxicity ratio was no significant difference.

Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic inflammatory skin disorder. Bristol Stool Form Scale (BSFS) is a widely used stool scoring method that could indirectly reflect intestinal function. OBJECTIVES To evaluate the associations of AD with BSFS. METHODS This was a population-based cross-sectional study of freshmen in five universities of China. AD diagnosis was performed by dermatologists according to the guideline from the American Academy of Dermatology. BSFS and covariates were collected through an online questionnaire survey. Chronic itch scores were assessed by the numeric rating scales and grouped into quartiles (Q). Mixed logistic regression models were used. Subgroup analysis was conducted by covariates. P value < 0.05 was considered statistically significant. RESULTS The prevalence of hard stools and loose stools were 8.9% and 7.6%, respectively (20,049 participants). After adjusting covariates, AD was significantly associated with hard stools (OR = 1.38, P < 0.001) and loose stools (OR = 1.24, P = 0.037). In subgroup analysis of hard stool, a stronger effect was observed in intake of milk (> 3 days/week), yogurt (> 3 days/week), pork (< 1 day/week), and higher itch scores (Q4). CONCLUSION This study found the relationship between AD and abnormal stool forms, and the association with hard stools might be modified by dietary factor.

Abstract
Objective: To understand ten-year changes in clinical characteristics and antiviral treatment patterns of chronic hepatitis B in China. Methods: Patients with chronic HBV infection:demographic, virologic, hematologic, blood biochemistry, and antiviral treatment data were extracted from the China Registry of Hepatitis B (CR-HepB) database between 2012 and 2022 for descriptive statistics and change trend analysis. Multiple group comparisons were conducted using the Kruskal Wallis H test, while counting data was compared between groups using χ (2) test. Results: A total of 180 012 patients with chronic HBV infection were included, with a median age of 40 years old, and a male proportion accounting for 60.2%. The HBeAg positive rate was 43.3%. Over time, the median age of new patients each year increased from 39 to 47 years, while the HBeAg positive rate decreased from 51.3% to 32.8%. The initial diagnosis of patients was mainly CHB (71.4%), followed by hepatitis B cirrhosis (11.8%), inactive HBsAg carrier status (10.6%), and chronic HBV carrier status (6.2%). Among the newly registered patients every year from 2012 to 2022, the proportion of hepatitis B cirrhosis remained stable, but after 2019, the proportion of CHB increased and the proportion of other diagnoses decreased. The proportion of patients with cirrhosis increased with age in different age groups, with 3.5%, 19.3%, and 30.4% in the < 40, 40-69, and≥70 age groups, respectively. The proportion of women in patients with cirrhosis also increased with age, from 16.1% in those < 30 years old to 44.3% in those≥80 years old. From 2012 to 2022, the proportion of patients receiving first-line nucleos(t)ide analog antiviral treatment increased year by year, from 51.0% in 2012-2013 to 99.8% in 2022. Conclusion: The CR-HepB registration data reflect the changes in clinical characteristics and antiviral treatment patterns in patients with chronic HBV infection in China over the past ten years and can thus provide a reference to promote hepatitis B diagnosis and treatment practice, as well as scientific research.

Abstract
PURPOSE To investigate the differences in higher-order aberrations between non-toric or toric implantable collamer lens (ICL or TICL) V4c implantation and simulated spectacle correction. METHODS Patients with high myopia who underwent ICL/TICL V4c implantation were enrolled. The "total no defocus" pattern of iTrace aberrometry to simulate the condition of spectacle correction was measured before ICL/TICL implantation, and higher-order aberrations in this condition were compared to those 3 months after surgery. Related factors with changes in coma were comprehensively analyzed. RESULTS A total of 89 right eyes of 89 patients were included. Compared to simulated spectacle correction, total-eye coma (P<0.0001 ICL, P<0.0001 TICL) and internal coma (P<0.0001 ICL, P<0.001 TICL) decreased in the ICL- and TICL-treated groups after surgery. Total-eye secondary astigmatism (P<0.0001 ICL, P=0.007 TICL) and internal secondary astigmatism (P<0.0001 ICL, P=0.009 TICL) were also decreased in both groups postoperatively. Spherical error showed positive correlations with variation in total-eye coma (r=0.37, P=0.004 ICL; r=0.56, P=0.001 TICL) and internal coma (r=0.30, P=0.02 ICL and r=0.45, P=0.01 TICL). Axial length revealed negative correlations with changes in total-eye coma (r=-0.45, P<0.001 ICL; r=-0.39, P=0.03 TICL) and internal coma (r=-0.28, P=0.03 ICL and r=-0.42, P=0.02 TICL). CONCLUSIONS Both ICL- and TICL-treated groups demonstrated a decrease in coma and secondary astigmatism after 3 months, postoperatively. ICL/TICL may confer a compensatory effect on coma aberration and secondary astigmatism. Patients with a higher myopia achieved a greater improvement in coma and may benefit more from ICL/TICL implantation than from spectacle correction implantation than from spectacle correction.

Abstract
The main pathogenic factor in atopic dermatitis (AD) is Th2 inflammation, and levels of serum CCL17 and CCL22 are related to severity in AD patients. Fulvic acid (FA) is a kind of natural humic acid with anti-inflammatory, antibacterial, and immunomodulatory effects. Our experiments demonstrated the therapeutic effect of FA on AD mice and revealed some potential mechanisms. FA was shown to reduce TARC/CCL17 and MDC/CCL22 expression in HaCaT cells stimulated by TNF-α and IFN-γ. The inhibitors showed that FA inhibits CCL17 and CCL22 production by deactivating the p38 MAPK and JNK pathways. After 2,4-dinitrochlorobenzene (DNCB) induction in mice with atopic dermatitis, FA effectively reduced the symptoms and serum levels of CCL17 and CCL22. In conclusion, topical FA attenuated AD via downregulation of CCL17 and CCL22, via inhibition of P38 MAPK and JNK phosphorylation, and FA is a potential therapeutic agent for AD.

Abstract
BackgroundIdiopathic inflammatory myopathies are a group of disorders associated with myositis-specific antibodies (MSA) and myositis-associated antibodies (MAA) (1). MSA and MAA are helpful in classifying clinical syndromes with both treatment and prognostic implications (2). Ordering of MSA and MAA has increased in recent years. We report the hospital services that ordered MSA and MAA and follow-up investigations performed in two large referral centers in Melbourne, Australia.ObjectivesTo explore and investigate the testing patterns of MSA and subsequent follow up.MethodsWe identified all patients who underwent MSA and MAA testing between January 1 2019 and December 31 2020. Relevant demographic and clinical data were obtained by chart review.ResultsOver the 2-year study period, 294 MSA tests were ordered, alongside 275 ANA and 266 ENA. Of these, 60 (20.4%) were positive and 9 (3.1%) tested positive to more than one MSA. Interstitial lung disease (ILD) was the most common extra-muscular manifestation, 42 (14.2%) had muscle disease manifestations. Respiratory (41%), rheumatology (24%) and neurology (15%) were the top three specialties ordering the most MSA, with the highest proportion of positive MSA originating from rheumatology (38.5%). The rheumatology service was involved in 131 (41.0%) of the MSA ordered as the primary treating unit or as a consultation service. Anti-Scl100 was the most common MSA (n=10, 15.6%). Among the 60 patients with positive MSA, 39 (65%) was given a definitive diagnosis, 13 (21.7%) underwent MRI of muscles, 10 (16.7%) open muscle biopsy, and 5 (8.3%) a skin biopsy. Thirty-two (53.3%) of MSA positive patients underwent high-resolution CT chest; 26 (81.3) % had findings suggestive of a fibrotic process and 12 (20.0%) had a formal diagnosis of ILD. A cancer screen was performed in 23 (38.3%) of the MSA positive patients and no malignancy was identified within the cohort.ConclusionAmong MSA studies performed in two large centers, 20.4% of results were positive. Respiratory ordered the most numerous tests predominantly to evaluate ILD, a higher proportion of tests recommended by the rheumatology service was positive.References[1]Targoff IN.

Abstract
Adenovirus infection can occur in all regions or countries of the world, with no obvious seasonality, but pandemics mostly occur in winter or early spring. Adenovirus infection is self-limited among immunocompetent host with supportive care, however fatal infection can occur among immunocompromised patients, mainly affecting respiratory, gastrointestinal tract and adjunctiva and very rarely causing hepatitis, cholecystitis, pancreatitis, hemorrhagic cystitis, myocarditis, meningitis or encephalitis. Adenovirus hepatitis mainly occur in malignant tumors or organ transplantation patients, but acute severe hepatitis can occur even in immunocompetent children or adults. On 5 April 2022, WHO was notified of 10 cases of severe acute hepatitis of unknown etiology in children. As of 21 April 2022, at least 169 cases of acute hepatitis of unknown origin have been reported from 12 countries (including 11 WHO European Region countries and the United States). Adenovirus has been detected in at least 74 cases; SARS-CoV-2 was identified in 20 cases of those that were tested. Furthermore, 19 were detected with a SARS-CoV-2 and adenovirus co-infection. At present, the etiology has not been fully elucidated. The leading hypotheses center around adenovirus, and the relationship with SARS-CoV-2 needs to be further ruled out.

Abstract
Liver involvement is often observed in hematological disorders, resulting in liver abnormality, including unconjugated hyperbilirubinemia, monoclonal hyperglobulinemia, portal vein, or hepatic vein thrombosis or portal hypertension, hepatosplenomegaly, or iron accumulation in the liver. Here we summarize the major hematological diseases that often affect the liver: hemolytic anemia, defect in coagulation or anti-coagulation factors, myeloproliferative neoplasm, hemophagocytic lymphohistiocytosis, multiple myeloma, leukemia, and lymphoma. We hope this review will help clinicians diagnose and manage the patients with liver involvement by hematological disorders.

Abstract
The impact of artificial light at night (ALAN) exposure on health has become increasingly prominent. However, little is known about the effect of ALAN exposure on atopic diseases. In this study, a cross-sectional analysis of incoming students was conducted in 5 geographically disperse universities which locate in Changsha (south), Wuhan (central), Xiamen (east), Urumchi (west), and Hohhot (north), respectively. All incoming students who consented to participate were recruited, followed by a health examination and a questionnaire survey. Prevalent atopic diseases were diagnosed by clinicians. Mean ALAN (nanoWatts/cm2/sr) during their adolescence was obtained from the remote sensing observed nighttime light data matching with their residence information, which was obtained from survey. Mixed generalized linear models (log-binomial) were used to estimate the associations, in terms of prevalence ratio (PR) with 95% confidence interval (CI). A total of 20106 participants were included in the analysis. Based on previous work, we chose factors including socioeconomic status, behavioural factors, major air pollutants, and air climatic parameters for adjustment. After full adjustment, the PR for atopic diseases was 1.35 (95% CI: 1.27-1.42; P < 0.001). The effect size of ALAN was the largest for asthma (PR = 1.80; 95% CI: 1.48-2.19; P < 0.001), followed by atopic rhinitis (PR = 1.42; 95% CI: 1.33-1.51; P < 0.001), and atopic dermatitis (PR = 1.20; 95% CI: 1.06-1.35; P = 0.003). Subgroup analyses by covariates showed consistent results. This study revealed that exposure to ALAN during adolescence may contribute to a higher risk of atopic diseases in young adulthood.

Abstract
Drought is the main factor restricting peanut growth, but the molecular mechanism underlying peanut drought tolerance remains unclear. Herein, the seedling stage of drought-resistant peanut cultivar J11 was subjected to drought stress, and its proteomic profile was systematically analysed by isobaric tags for relative and absolute quantification (iTRAQ), the results of which were further complemented with our previous transcriptome results. A total of 4,018 proteins were identified by proteomic analysis, which revealed that the expression levels of 69 proteins were altered under drought stress. Among the differentially expressed proteins (DEPs), 50 were upregulated, and 19 were downregulated. The most enriched metabolic pathways for these DEPs were those involving phenylpropanoid biosynthesis, flavonoid biosynthesis, and plant hormone signal transduction. The proteomic data and previous transcriptome results revealed 44 groups of genes/proteins with the same expression trend, including a LEA (Late embryogenesis abundant) gene, AhLEA2. Our present study showed that overexpression of the AhLEA2 gene enhanced the drought resistance of transgenic Arabidopsis plants, and the activities of related antioxidant enzymes in the transgenic plants significantly changed. The AhLEA2 gene was found to be located in the cytoplasm and cell membrane by subcellular localization experiments. This work systematically analysed the differentially expressed proteins in peanut in response to drought stress, providing important candidates for further functional analysis of the stress response of peanut. Our results also indicated that AhLEA2 plays an important role in the peanut response to drought stress.

Abstract
RATIONALE Coronary artery ligation to induce myocardial infarction (MI) and ischemia injury in mice is typically performed in normal mice, but This is not consistent with disease progression. There should be atherosclerosis (AS) first, followed by MI. OBJECTIVE We tried a novel model to induce MI that was established on atherosclerosis in mice. This approach was much more consistent with disease progression. METHODS In this study, Mice lacking apolipoprotein E (ApoE-/-) were randomly divided into four groups. The mice of the control and MI groups were fed normal diet for 24-weeks, while the mice of AS and AS + MI groups were fed high-fat diet (HFD). After 23 weeks, the mice of MI and AS + MI groups were ligated with coronary arteries. A week later, after echocardiography, analysis of plaque and myocardium were conducted on aortic and heart, then the serum, aorta and heart tissues were further detected. RESULTS Our results showed that AS model mice exhibited significant body weight gain, dyslipidemia and atherosclerotic lesions formation which were in accordance with the pathological changes of AS. Co-treatment with AS and MI led to higher operative mortality and heart pathological were in accordance with the pathological changes of MI. In addition, Echocardiography and NT pro-BNP revealed co-treatment with AS and MI led to deterioration of cardiac function. AS also aggravated myocardial inflammatory cell infiltration and fibrosis post-MI. CONCLUSIONS Together, it is feasible to establish myocardial infarction model based on atherosclerosis model.

Abstract
BACKGROUND Overuse and misuse of antibiotics is a public health problem in low-income and middle-income countries. Although the association of antibiotics with atopic and allergic diseases has been established, most studies focused on prenatal exposure and the occurrence of disease in infants or young children. OBJECTIVE To investigate the association of preschool use of antibiotics with atopic and allergic skin diseases in young adulthood. DESIGN Population-based retrospective cohort. SETTING AND PARTICIPANTS The first-year college students (n=20 123) from five universities were investigated. The sampled universities are located in Changsha, Wuhan, Xiamen, Urumqi and Hohhot, respectively. METHODS We conducted a dermatological field examination and a questionnaire survey inquiring the participants about the frequency of upper respiratory tract infection (URTI) and the preschool antibiotics use (prior to 7 years old). The two-level probit model was used to estimate the associations, and adjusted risk ratio (aRR) and 95% CI were presented as the effect size. RESULTS A total of 20 123 participants with complete information was included in the final analysis. The frequent antibiotics use intravenously (aRR 1.36, 95% CI 1.14 to 1.62) and orally (aRR 1.18, 95% CI 1.01 to 1.38) prior to 7 years old was significantly associated with atopic dermatitis in young adulthood. Similar trends could be observed in allergic skin diseases among those who use antibiotics orally and intravenously, with RRs of 1.16 (95% CI 1.01 to 1.34) and 1.33 (95% CI 1.13 to 1.57), respectively. CONCLUSIONS Preschool URTI and antibiotics use significantly increases the risk of atopic and allergic skin diseases in young adulthood.

Abstract
Helianthus Annuus L. (HAL) is composed of flavonoids and polysaccharides. Flavonoids have demonstrated beneficial effects on atherosclerosis (AS). The objective of this study was to investigate the anti-atherosclerosis effect and the related mechanism of HAL. In this study, the AS model induced by high-fat diet (HFD) mice that lacked apolipoprotein E (Apoe[Formula: see text] received feed containing 5% HAL for 24 weeks. After administration, the analysis of plaque on aorta was conducted, and the possible mechanisms were further explored. With HAL treatment, the size of atherosclerotic lesions in HFD-induced AS model mice was reduced. HAL ameliorated dyslipidemia and decreased the combined ratio. HAL up-regulated concentrations of superoxide dismutase (SOD), nitric oxide (NO) and glutathione peroxidase (GSH-Px) and down-regulated concentrations of malondialdehyde (MDA) in the aorta. In addition, 16S rRNA analysis showed that HAL also reduced diversity of the intestinal microbiota, decreased the Firmicutes-to-Bacteroidetes ratio, and increased the relative abundance of probiotics such as Akkermansia muciniphila and Lactobacillus. In the end, HAL decreased the permeability of intestine by increasing the levels of occludin and tight junction protein 1 (ZO-1) in the colon, consequently decreasing concentration of interleukin (IL)-6, IL-1[Formula: see text] and tumor necrosis factor-alpha (TNF-[Formula: see text] in serum and mRNA expressions in the aorta. Data showed that HAL alleviates AS by restraining oxidative stress, regulating intestinal microbiota, decreasing intestinal permeability and inhibiting inflammation. Our findings provided novel insights into the role and mechanism of anti-atherogenic potential of HAL.

Abstract
Overdose acetaminophen (APAP) can result in severe liver injury, which is responsible for nearly half of drug-induced liver injury in western countries. Previous studies have found that there existed massive hepatocellular necrosis and severe inflammatory response in APAP-induced liver injury. However, the mechanistic linkage between necroptosis and NLRP3 inflammasome pathway in APAP-induced hepatotoxicity remains poorly understood. In order to investigate the relationship between inflammation and hepatocytes death in APAP hepatotoxicity, a time-course model for APAP hepatotoxicity in C57/BL6 mice was established by intraperitoneal (i.p) injection of 300 mg/kg APAP in this study. The activity of serum enzymes and pathological changes of APAP-treated mice were evaluated, and the critical molecules in necroptosis and NF-κB-NLRP3 inflammasome signaling pathway were determined by immunoblot and immunofluorescence analysis. The results demonstrated that APAP overdose resulted in a severe liver injury. Furthermore, the expression of critical molecules in NLRP3 inflammasome and necroptosis pathways peaked at 12-24 h, and then was decreased gradually, which is consistent with the pattern of pathological injury induced by APAP. Our further investigation found that the level of IL-1β in mouse liver was closely correlated with the level of phosphorylated MLKL following exposure to APAP. Furthermore, inhibition of necroptosis with necrostatin-1 significantly suppressed the activation of NLRP3 inflammasome signaling. Taken together, our results highlighted that the cross-talk between necroptosis and NLRP3 inflammasome played a critical role for promoting APAP-induced liver injury. Inhibition of the interaction of inflammation and necroptosis by pharmaceutical methods may represent a promising therapeutic strategy for APAP-induced liver injury.

Abstract
Objectives: It is understudied how frequently adolescents use nutritional supplements (NS) and whether the corresponding behavior is associated with skin diseases that may cause unpleasant symptoms and disfigurement. The current study aimed to investigate the prevalence of NS use in Chinese college students and its association with inflammatory skin diseases. Methods: This was a university-based epidemiologic investigation that included 20,138 students who underwent dermatological examinations. A questionnaire survey was conducted to inquire about the use of NS along with related information. Skin diseases were diagnosed by dermatologists during the health examination. Logistic regression models were used for analysis. Adjusted odds ratios (aORs) were presented as the effect size. Results: Survey responses from a total of 20,138 participants were analyzed. Specifically, 18.3% of the participants reported the use of NS in the past year. The use of vitamin C was most frequently reported, accounting for a proportion of 12.9%, followed by vitamin B and mineral supplements. The use of NS was found to be associated with female sex, Han ethnicity, higher annual household income, and a series of healthy lifestyles such as more physical activity, less second-hand smoke exposure, less alcohol consumption, and higher intake of milk and yogurt (p < 0.001). Participants with chronic urticaria (aOR = 1.3; 95% CI, 1.0–1.7), atopic dermatitis (aOR = 1.4; 95% CI, 1.2–1.6), or acne (aOR = 1.17; 95% CI, 1.04–1.31) were more likely to use NS, especially herbs (aOR = 2.7; 95% CI, 1.2–3.7), followed by vitamin B (aOR = 1.6; 95% CI, 1.2–2.0) and mineral supplements (aOR = 1.4; 95% CI, 1.0–2.0). Conclusion: College students with inflammatory skin diseases are more likely to use NS.

Abstract
OBJECTIVE Glycogen phosphorylase B (PYGB), the rate-determining enzyme in glycogen degradation, plays a critical role in progression of various tumors. The present study focused on the potential molecular mechanism toward PYGB in non-small cell lung cancer (NSCLC) progression. METHODS Expression of PYGB in NSCLC tissues and cell lines was evaluated via quantitative real-time PCR (qRT-PCR), western blot and immunohistochemistry. Cell viability, proliferation and apoptosis were investigated using 3-(4,5-Dimethylthiazol)-2,5-diphenyltetrazolium bromide (MTT) assay, 5-bromo-2-deoxyuridine (BrdU) and flow cytometry, respectively. Cell migration and invasion ability were detected by wound healing and transwell invasion assays, respectively. The in vivo effect of PYGB on NSCLC tumor growth was determined via subcutaneous xenotransplanted tumor model. RESULTS PYGB was upregulated in NSCLC tissues and cell lines, suggesting a poor prognosis in NSCLC patients. In vitro functional assays indicated that knockdown of PYGB suppressed cell viability, proliferation, migration and invasion, while promoted cell apoptosis in NSCLC. Mechanistically, we found that overexpression of PYGB could activate phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, while these effects were effectively reversed by knockdown of PYGB. In vivo tumorigenesis and PI3K/AKT signaling pathway were also inhibited by PYGB knockdown. CONCLUSIONS Knockdown of PYGB suppressed NSCLC progression, suggesting PYGB as a novel biomarker and potential molecular therapeutic target for further investigation in NSCLC.

Abstract
Pyroptosis is a programmed death mode dependent on Caspase-1/4/5/11, which is caused by activation of inflammasome, accompanied by cell membrane rupture, pore formation and cell content release. As a new type of cell death, it is widely involved in respiratory diseases, such as pulmonary fibrosis, acute lung injury, bronchopulmonary dysplasia, chronic obstructive pulmonary disease and asthma. This article reviews the mechanism of pyroptosis and its role in different respiratory diseases, in order to provide new ideas for the treatment of respiratory diseases.

Abstract
Objective: To describe the current status of registration and design characteristics of clinical trials of new drugs for curing hepatitis B through domestic and foreign websites, so as to provide references for the follow-up clinical trials of new hepatitis B drugs. Methods: A search was conducted on the US Clinical Trials Database and the Chinese Clinical Trial Registry Center. The search date was from the establishment of the database to May 26, 2020, and the registration trials of new drugs for curing hepatitis B at home and abroad were included. Two researchers independently searched and screened the literature and extracted the data. Results: A total of 106 registered clinical trials of new drugs for curing hepatitis B were included (94 English registration websites and 12 Chinese registration websites), and the number of registrations had increased year by year. Among them, the proportion of therapeutic vaccines and core protein inhibitors were the highest, accounting for 27.4% (n = 29) and 22.6% (n = 24), respectively. The vast majority of clinical trials (n = 96, 90.6%) were in the early stages (Phase I and II). The subjects in phase I clinical trial were mainly healthy people and treated CHB patients, while the subjects in phase II clinical trial were mainly CHB patients who had achieved viral suppression after initial or post-treatment. The main evaluation indicators of Phase I clinical trials were the safety and tolerability of new drugs. The main evaluation indicators in about half of Phase II clinical trials were HBsAg negative conversion/quantitative decline. Overall, the number of clinical trials with the new design was small, accounting for 3.8% (4 / 106). There were relatively few trials of new drugs for curing hepatitis B on domestic registration websites, and the information provided was incomplete. Conclusion: The number of clinical trials of new hepatitis B drugs at home and abroad is increasing year by year, but most of them are in phase I and II, with few adopting new designs. In addition, the information integrity of the domestic website registration center needs to be improved.

Abstract
Smoking has been identified as a risk factor for atopic dermatitis and hand eczema, but less is known about the association of exposure to second-hand smoke (SHS) with hand eczema. The study aimed to investigate the association of SHS exposure with hand eczema and atopic dermatitis in a group of adolescents. We conducted a cross-sectional study among first-year college students. SHS exposure was measured by a self-administered questionnaire. Skin diseases were diagnosed by dermatologists in the field survey. Mixed models were used to estimate the associations. A total of 20,129 participants that underwent skin examination and a questionnaire survey were included in the analyses. The prevalence rates of atopic dermatitis and hand eczema were 3.86% and 3.35%, respectively. Crude and adjusted estimates consistently showed that exposure to SHS was significantly associated with atopic dermatitis and hand eczema in a dose–response manner. Attention deficit/hyperactivity disorder mediated minimal or no effect of SHS on hand eczema and atopic dermatitis. Subgroup analysis by type of hand eczema, and sensitivity analysis by excluding data with center effect showed consistent results. Exposure to SHS is an independent but modifiable risk factor for hand eczema and atopic dermatitis in adolescents.

Abstract
Background The prevalence and health-related quality of life of skin disease have been understudied in adolescents. Objective To investigate the prevalence and relevant patient-reported outcomes of noncommunicable skin diseases in college students. Methods First-year college students from 5 universities in China were investigated in the cross-sectional study. Skin diseases were diagnosed by dermatologists in the field survey. Itch and pain, symptoms of depression and anxiety, and sleep quality were measured by validated tools. Results A total of 28,364 students consented to participate and completed the survey. The prevalence of acne, eczema, chronic urticaria, psoriasis, and vitiligo was 10.3%, 5.8%, 2.6%, 0.16%, and 0.23%, respectively. Eczema and chronic urticaria were associated with lower health utility estimates. Most diseases, but not psoriasis and vitiligo, were associated with the symptoms of depression and sleep disturbance. Itch intensity predicted other patient-reported outcome scores better in healthy controls than in individuals with skin diseases. Sex difference in the associations of skin diseases with patient-reported outcomes was not identified. Limitations Cross-sectional study design and limited generalizability to the nonstudent population. Conclusion Skin diseases are associated with moderately impaired emotional well-being, sleep quality, and quality of life, partly attributable to cutaneous symptoms.

Abstract
OBJECTIVE To investigate the role of long non-coding RNA Cancer Susceptibility Candidate 15 (CASC15) in cervical cancer and its potential molecular mechanism. PATIENTS AND METHODS The CASC15 expression was measured in cervical cancer tissues and cell lines by using quantitative Real-time polymerase chain reaction (qRT-PCR) analysis. Cell counting kit-8 (CCK8), flow cytometry analysis and transwell cell invasion assays were employed to detect the capacities of cell proliferation and cell invasion. Furthermore, Western blot analysis was applied to detected the E-cadherin and N-cadherin expression in EMT pathway. RESULTS We demonstrated that lncRNA CASC15 expression was higher in cervical cancer tissues compared to adjacent normal tissues. Higher lncRNA CASC15 expression associated with lymph node metastasis and FIGO stage. Moreover, our results showed that higher lncRNA CASC15 expression predicted poor prognosis of cervical cancer. Functional assays showed that knockdown of lncRNA CASC15 suppressed cell proliferation and cell cycle progression in cervical cancer. Moreover, we also found that knockdown of lncRNA CASC15 inhibited cell invasion ability and Epithelial-Mesenchymal Transition (EMT) signaling pathway by upregulating E-cadherin and downregulating N-cadherin expression in cervical cancer. CONCLUSIONS These results indicated that lncRNA CASC15 expression may be a prognostic biomarker and contributed to cell proliferation and invasion in cervical cancer.

Abstract
AbstractObjective:To study the effect of obstructive sleep apnea(OSA) on the life quality of children. Method: Forty-four OSA children diagnosed with overnight polysomnography were selected as the research object, 35 cases of pediatric no snoring healthy children were as control. The inventory of subjective life quality and children's self-rating anxiety scale were used to assess children' s life quality. Result: Depending on the data of the inventory of subjective life quality questionnaire, each level and dimension of children' s life quality satisfaction scores in OSA group were significantly lower than that in healthy controls(P<0.05), especially in the cognitive component of school life(3.78±1.73) and the affective component of depression experience(3.70±2.18). The score of anxiety disorder in OSA group (21.39±10.49) was higher than that in healthy control group(14.21±9.69)( P<0.05). The rate of anxiety disorder in OSA group was higher than that in healthy control group(P<0.05). Conclusion:Children in OSA group had higher incidence of unsatisfactory life quality in all levels and dimensions. OSA group children dissatisfied with the life quality in each level, each dimensions have significant statistical difference, especially in the cognitive component of school life and affective components of depression experience. The OSA group had higher anxiety disorders than healthy ones.

Abstract
Background The anti-microbial protein cathelicidin LL-37 plays an important role in the pathogenesis of psoriasis by inducing inflammation. Our previous study showed that the chlamydial plasmid-encoded protein pGP3 forms a stable complex with LL-37 to neutralize its pro-inflammatory activity. Here, we explored whether pGP3 can inhibit the development of lesions in mice with imiquimod-induced psoriasis. Material/Methods The protein pGP3 was expressed in bacteria and purified using glutathione-conjugated agarose beads and a precision protease. The ability of the purified pGP3 to block chemotaxis mediated by LL-37 was tested in vitro using bone marrow-derived neutrophils. The ability of the protein to inhibit the development of psoriasis-like lesions was tested by topically or subcutaneously administering pGP3 in doses of 10 or 50 μg to mice previously treated with imiquimod. Mouse skin was evaluated using the psoriasis area and severity index (PASI) score and photography. Skin biopsies were taken on day 8 and analyzed histologically. Results Purified pGP3 inhibited LL-37-mediated chemotaxis. Mice treated with 50 μg pGP3 showed clinical improvement with less severe erythema, infiltration, and scales; these mice also showed thinner dermis and less hyperkeratosis, parakeratosis, and inflammatory cell infiltration than mice treated with without 10 μg pGP3. Conclusions PGP3 can inhibit the development of psoriasis-like lesions in mice, possibly through its ability to bind LL-37. Future work should examine the mechanisms underlying this therapeutic effect.

Abstract
Odorant receptors (ORs) expressed in the antennae of parasitoid wasps are responsible for detection of various lipophilic airborne molecules. In the present study, 107 novel OR genes were identified from Microplitis mediator antennal transcriptome data. Phylogenetic analysis of the set of OR genes from M. mediator and Microplitis demolitor revealed that M. mediator OR (MmedOR) genes can be classified into different subfamilies, and the majority of MmedORs in each subfamily shared high sequence identities and clear orthologous relationships to M. demolitor ORs. Within a subfamily, six MmedOR genes, MmedOR98, 124, 125, 126, 131 and 155, shared a similar gene structure and were tightly linked in the genome. To evaluate whether the clustered MmedOR genes share common regulatory features, the transcription profile and expression characteristics of the six closely related OR genes were investigated in M. mediator. Rapid amplification of cDNA ends-PCR experiments revealed that the OR genes within the cluster were transcribed as single mRNAs, and a bicistronic mRNA for two adjacent genes (MmedOR124 and MmedOR98) was also detected in female antennae by reverse transcription PCR. In situ hybridization experiments indicated that each OR gene within the cluster was expressed in a different number of cells. Moreover, there was no co-expression of the two highly related OR genes, MmedOR124 and MmedOR98, which appeared to be individually expressed in a distinct population of neurons. Overall, there were distinct expression profiles of closely related MmedOR genes from the same cluster in M. mediator. These data provide a basic understanding of the olfactory coding in parasitoid wasps.

Abstract
Objective:To investigate metformin's effect on chemosensitivity of chemotherapeutic drug 5-fluorouracil in laryngocarcinoma Hep-2 cells. Investigate the variation trend of protein expression of AMPK pathway in the combined effect.Method:Laryngocarcinoma Hep-2 cells were treated with different concentrations of 5-fluorouracil in vitro together with or without metformin for 72 h. Use MTT assay to investigate the influence on the inhibition rate to Hep-2 cells. Hep-2 cells were treated with cisplatin, 5-fluorouracil or paclitaxel with or without metformin. Use Western blot assay to investigate the expression level of AMPKα, P21 or Cyclin D1 protein. Result:5-fluorouracil and metformin could inhibit the proliferation of Hep-2 cells. 5-fluorouracil in low concentration combined with metformin could increase the proliferation inhibition rate of Hep-2 cells. In the circumstances of using 5-fluorouracil in high concentration with metformin , the cell proliferation inhibition rate of combining group makes no differences with the single-drug group. The combination of metformin and 5-fluorouracil produced an antagonism action in Hep-2 cells.Western blot assay showed that metformin, cisplatin, 5-fluorouracil could have caused the increase of expression level of AMPK-α, P21 and Cyclin D1 in Hep-2 cells while Paclitaxel could have cause the decrease of expression level of Cyclin D1. Using combined drug could cause the change of protein expression. Conclusion:5-fluorouracil has been found to inhibit the proliferation of Hep-2 cells. Metformin has an antagonism on the anticancer effect to 5-fluorouracil in Hep-2 cells, and this antagonistic effect occurred partially through molecular signal pathways of AMPK-α, P21 and Cyclin D1 and it's significantly related to the cell cycle arrest.

Abstract
Objective: To investigate the possibility of the Protein Phosphatase 2A (PP2A) inhibitor, LB100, in reversing acquired resistance to gefitinib in lung adenocarcinoma with epidermal growth factor receptor (EGFR) gene mutation. Methods: Cell line NCI-H1975 and established primary culture cell line 44-1 with gefitinib resistance were sequenced to determine the mutation type of EGFR gene. Cells were treated with gefitinib alone or combined with LB100 to determine the half maximal inhibitory concentration (IC50), and sensitivity of 44-1 and NCI-1975 to gefitinib alone or combined with LB100 was compared. The volume of NCI-H1975 xenografts with different drug treatments was observed to determine the efficiency of gefitinib with or without LB100 in tumor growth inhibition. Results: Both 44-1 and NCI-1975 cells had double EGFR mutation (sensitive L858R mutation and resistant T790M mutation). Both cells showed significant gefitinib resistance (IC50: 23.0 μmol/L in 44-1, 16.7 μmol/L in NCI-1975). When combined with LB100, IC50 of gefitinib decreased to 6.9 μmol/L in 44-1 cell and decreased to 3.4 μmol/L in NCI-H1975 cells. In NCI-1975 xenografts experiments, LB100 enhanced the ability of gefitinib in tumor growth inhibition (P<0.05). Conclusion: LB100 reverses acquired resistance to gefitinib in lung adenocarcinoma cell lines.

Objective:To explore the molecular mechanism of neural plasticity in the reconstitution following impairment of auditory system,we studied the changing levels of GAP-43 expression in the auditory cortex(AC) in the developing rats and in ototoxicity deafened rats before and after electrical intracochlear stimulation.Method:Auditory brain stem response(ABR) measurements were performed to rats of OAD,NC1,CAD and NC2 group to evaluate hearing function.We studied the changing levels of GAP-43-positive neurons expression in the auditory cortex of the OAD,NC1,EIS1 and EIS2 group and RT-PCR was performed to do semiquantitative analysis.Result:The early electrical intracochlear stimulation elevated GAP-43 level(EIS1,120.00±5.59/HP) in ipsilateral AC instead of in the contralateral AC compared with the non-stimulation group (OAD4W,93.25±4.30/HP),and the two groups had statistical difference(EIS1/OAD4W,129.17%±3.33%,P<0.05).After the late electrical intracochlear stimulation,similar to the early group,the staining level of GAP-43(EIS2,102.50±4.02/HP) in the AC was also higher than the unaffected group(OAD8W,81.67±3.76/HP),and the two groups also had statistical difference(EIS2/OAD8W,123.74%±2.70%,P<0.05).Similarly,the expression of GAP-43 mRNA had the synchronous change with the GAP-43 in the AC.Conclusion:GAP-43 has close correlation with the growth and plasticity of the AC,which can be a significant marker for auditory plasticity.

Abstract
AIM This study aimed to determine the degree of discrepancy between clinical measurement of furcation involvement (FI) and cone beam computed tomography image analysis of multirooted teeth. METHODS FI measurements obtained from clinical records were compared to CBCT images of the same teeth to determine the degree of discrepancy between CBCT FI grading and clinical FI grading. RESULTS Of the hundred and fifty-four sites analysed, 22% of FI measurements from probing and CBCT were in agreement. Fifty-eight percent of clinical FI recordings were overestimated, and 20% were underestimated when compared to CBCT analysis. CONCLUSION Clinical recording of FI is both over and underestimated compared to CBCT analysis. This was highest for probing recording grade I furcation involvement where it was highly overestimated. The occurrence of over and under estimation of FI will affect the assignment of prognosis to multirooted teeth, which can influence treatment planning for periodontal therapy and may result in inappropriate treatment.

Abstract
Interferon (IFN) activation signaling and T helper 17 (Th17)-cell/B-cell regulation play a critical role in the pathogenesis of systemic lupus erythematosus (SLE). Several studies have provided convincing evidence that polymorphisms in IRF5, STAT4, IKZF1 and ETS1 from these pathways may be involved in SLE by affecting gene expression or epistasis. We analyzed the genetic interaction in known SLE susceptibility loci from the four genes in northern Han Chinese. A total of 946 northern Han Chinese participated in this study (370 unrelated SLE patients and 576 healthy controls). Subjects underwent genotyping for the single-nucleotide polymorphisms (SNPs) rs2004640 in IRF5, rs7574865 in STAT4, rs4917014 in IKZF1 and rs1128334 in ETS1 by use of a TaqMan SNP genotyping assay and direct sequencing. Gene-gene interaction analysis involved direct counting, multifactor dimensionality reduction (MDR) and linear regression analysis. SLE patients and controls differed in allele frequencies of rs7574865, rs1128334 (P < 0.001) and rs4917014 (P < 0.01). Direct counting revealed that the frequency of risk homozygote combinations was higher for SLE patients than controls (P < 0.01). Furthermore, 2-, 3- and 4-way gene-gene epistasis in SLE was confirmed by parametric methods and MDR analysis. Gene expression analysis partially supported the findings. Our study confirmed the association of the IFN pathway or Th17/B-cells and the pathogenesis of SLE, and gene-gene interaction in this pathway may increase the risk of SLE.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease of uncertain etiology that affects multiple tissues and organs. Arsenic trioxide (ATO) has been used in lupus-prone mice with a regulatory effect on immune abnormality. Tetra-arsenic tetra-sulfide (As4S4), a traditional Chinese medicine, is effective on acute promyelocytic leukemia with mild side effects than ATO. In this study, a pilot study was performed to investigate the effects and the mechanism of As4S4 on the lupus-prone BXSB mice. Improvement of monocytosis (p<0.05) in spleen and decreased serum interleukin-6 (IL-6) (p=0.0277) were observed with As4S4 treatment. As4S4-treated mice exhibited amelioration of skin, liver and renal disease with mild side effects. Histological analysis revealed that As4S4 suppressed immune complex deposition, mesangial proliferation and inflammatory cell infiltration in kidney and liver. Our study support that As4S4 selectively suppresses cutaneous lupus and nephritis in BXSB mice and might be a potential treatment for SLE.

Abstract
Noble-transition metal (noble=Pt,Au; transition=Co,Ni,Cu) alloy particles with sizes of about 5 nm have been studied by in situ high-energy x-ray diffraction while subjected to oxidizing (O(2)) and reducing (H(2)) gas atmospheres at elevated temperatures. The different gas atmospheres do not affect substantially the random alloy, face-centered-cubic structure type of the particles but do affect the way the metal atoms pack together. In an O(2) atmosphere, atoms get extra separated from each other, whereas, in an H(2) atmosphere, they come closer together. The effect is substantial, amounting to 0.1 Å difference in the first neighbor atomic distances, and concurs with a dramatic change of the particle catalytic properties. It is argued that such reactive gas induced "expansion shrinking" is a common phenomenon that may be employed for the engineering of "smart" nanoparticles responding advantageously to envisaged gas environments.

Abstract
Two recent genome-wide association studies of East Asian populations revealed three genetic variants in WDFY4/LRRC18 associated with systemic lupus erythematosus (SLE). To identify the gene contributing to this disease susceptibility, we examined the mRNA expression of WDFY4 and LRRC18 in patients with SLE and healthy controls. WDFY4 was significantly downregulated in SLE patients as compared with controls. We used allelic expression and dual-luciferase assays to identify the functional variant. Transcriptional activity was lower for the rs877819A than -G allele. Electrophoretic mobility shift and supershift assays revealed that the transcription factor Yinyang1 (YY1) binds to rs877819, with lower affinity to the A allele, which explained the reduced transcriptional activity. This effect was further confirmed by YY1 small interfering RNA knockdown, overexpression and chromatin immunoprecipitation experiments. rs877819 in WDFY4 might be the functional site associated with SLE by reduced binding of YY1 and downregulating WDFY4 expression.

Abstract
OBJECTIVE To explore the effects of islet neogenesis- associated protein pentadecapeptide (INGAP-PP) on proliferation and secretion function of β-cells. METHODS Islets of adult Sprague Dawley rats were isolated by collagenase digestion and treated with 10 μg/ml INGAP-PP, after 12, 24, 48 h, glucose-stimulated insulin secretion (GSIS) and acridine orange/pro pidium iodide (AO/PI) staining were used to detect the secretion function and cell viability. The INS-1 cells were treated with 0, 1, 10, 25, 50, 100, 250, and 500 μg/ml INGAP-PP for 24 or 48 h, MTT cell proliferation assay was adopted to survey the dose-response relationship between INGAP-PP and cell proliferation. The mRNA expression of roliferating cell nuclear antigen (PCNA), Cyclin D1, Cdk4, P27, p38MAPK, and JNK in INS-1 cells were examined by RT-PCR, and the protein expression of PCNA was examined by Western blot. The statistical significance was determined by Student's t-test or one-way analysis of variance. RESULTS The insulin secreted by islets and the cell viability were increased by INGAP-PP. MTT indicated a dose-response relationship between INGAP-PP and quantity of INS-1 cells, and treatment for 48 h had a stronger effect on cell proliferation than the 24 h. INGAP-PP up-regulated the mRNA expression of PCNA, Cyclin D1, Cdk4 and downregulated P27, p38MAPK, and JNK. Moreover, the protein expression of PCNA was up-regulated by 45% after INGAPPP exposure for 48 h. CONCLUSIONS INGAP-PP increased the insulin secretion, enhanced the proliferation and might reduce apop tosis of β-cells. The mechanism may contribute to the changed expression of some genes related to cell cycle.

Abstract
Soft cellular structures that comprise a solid matrix with a square array of holes open avenues for the design of novel soft and foldable structures. Our results demonstrate that by simply changing the shape of the holes the response of porous structure can be easily tuned and soft structures with optimal compaction can be designed.
