Abstract
Tissue-specific mechanisms regulate neutrophil immunity at the oral barrier, which plays a key role in periodontitis. Although it has been proposed that fibroblasts emit a powerful neutrophil chemotactic signal, how this chemotactic signal is driven has not been clear. The objective of this study was to investigate the site-specific regulatory mechanisms by which fibroblasts drive powerful neutrophil chemotactic signals within the oral barrier, with particular emphasis on the role of the IL-36 family. The present study found that IL-36γ, agonist of IL-36R, could promote neutrophil chemotaxis via fibroblast. Single-cell RNA sequencing data disclosed that IL36G is primarily expressed in human and mouse gingival epithelial cells and mouse neutrophils. Notably, there was a substantial increase in IL-36γ levels during periodontitis. In vitro experiments demonstrated that IL-36γ specifically activates gingival fibroblasts, leading to chemotaxis of neutrophils. In vivo experiments revealed that IL-36Ra inhibited the infiltration of neutrophils and bone resorption, while IL-36γ promoted their progression in the ligature-induced periodontitis mouse model. In summary, these data elucidate the function of the site-enriched IL-36γ in regulating neutrophil immunity and bone resorption at the oral barrier. These findings provide new insights into the tissue-specific pathophysiology of periodontitis and offer a promising avenue for prevention and treatment through targeted intervention of the IL-36 family.

Abstract
BACKGROUND KEYNOTE-522 demonstrated statistically significant improvements in pathological complete response (pCR) with neoadjuvant pembrolizumab plus chemotherapy and event-free survival (EFS) with neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab in patients with high-risk, early-stage triple-negative breast cancer (TNBC). Prior studies have shown the prognostic value of the residual cancer burden (RCB) index to quantify the extent of residual disease after neoadjuvant chemotherapy. In this preplanned exploratory analysis, we assessed RCB distribution and EFS within RCB categories by treatment group. PATIENTS AND METHODS A total of 1174 patients with stage T1c/N1-2 or T2-4/N0-2 TNBC were randomized 2 : 1 to pembrolizumab 200 mg or placebo every 3 weeks given with four cycles of paclitaxel + carboplatin, followed by four cycles of doxorubicin or epirubicin + cyclophosphamide. After surgery, patients received pembrolizumab or placebo for nine cycles or until recurrence or unacceptable toxicity. Primary endpoints are pCR and EFS. RCB is a prespecified exploratory endpoint. The association between EFS and RCB was assessed using a Cox regression model. RESULTS Pembrolizumab shifted patients into lower RCB categories across the entire spectrum compared with placebo. There were more patients in the pembrolizumab group with RCB-0 (pCR), and fewer patients in the pembrolizumab group with RCB-1, RCB-2, and RCB-3. The corresponding hazard ratios (95% confidence intervals) for EFS were 0.70 (0.38-1.31), 0.92 (0.39-2.20), 0.52 (0.32-0.82), and 1.24 (0.69-2.23). The most common first EFS events were distant recurrences, with fewer in the pembrolizumab group across all RCB categories. Among patients with RCB-0/1, more than half [21/38 (55.3%)] of all events were central nervous system recurrences, with 13/22 (59.1%) in the pembrolizumab group and 8/16 (50.0%) in the placebo group. CONCLUSIONS Addition of pembrolizumab to chemotherapy resulted in fewer EFS events in the RCB-0, RCB-1, and RCB-2 categories, with the greatest benefit in RCB-2. These findings demonstrate that pembrolizumab not only increased pCR rates, but also improved EFS among most patients who do not have a pCR.

Abstract
Depression is considered to be an "emotional disease" in ancient books of traditional Chinese medicine. Its clinical features are similar to those of "Lily disease" in the ancient Chinese medicine book Synopsis of the Golden Chamber written by Zhang Zhongjing in the Han Dynasty. Baihe Zhimu (Lilium lancifolium bulb and Anemarrhena asphodeloides rhizome) decoction (LBRAD) is the first prescription of "Lily Disease" in this book. It is also a special remedy for "Lily disease" after sweating. The classic recipe LBRAD consists of two herbs, fresh lily bulbs and dried Rhizoma Anemarrhena slice. It has the effect of supplementing nutrition and clearing heat, nourishing Yin and moistening. After more than two thousand years of clinical practice, it has been currently widely used in clinical treatment of depression. In this paper, the relationship between LBRAD and depression was systematically reviewed from both clinical and experimental studies, as well as the preparation, the clinical application, the pharmacological mechanism and the effective material basis for the treating depression of LBRAD. The core targets and biological processes of the depression treatment were explored through network pharmacological analysis, so as to speculate its potential mechanism. Finally, the association between LBRAD and post-COVID-19 depression was discussed. We concluded with a summary and future prospects. This review may provide a theoretical basis for the expansion of the clinical application of LBRAD and the development of new drugs for the treatment of depression, as well as new ideas for the secondary development of classical prescriptions.

Abstract
This work involves theoretical and numerical analysis of the thermal quasi-geostrophic (TQG) model of submesoscale geophysical fluid dynamics (GFD). Physically, the TQG model involves thermal geostrophic balance, in which the Rossby number, the Froude number and the stratification parameter are all of the same asymptotic order. The main analytical contribution of this paper is to construct local-in-time unique strong solutions for the TQG model. For this, we show that solutions of its regularised version α -TQG converge to solutions of TQG as its smoothing parameter α → 0 and we obtain blow-up criteria for the α -TQG model. The main contribution of the computational analysis is to verify the rate of convergence of α -TQG solutions to TQG solutions as α → 0 , for example, simulations in appropriate GFD regimes.

Abstract
OBJECTIVE To explore the protective effect and related mechanism of miR-140-5p on liver fibrosis by interfering with TGF-β/Smad signaling pathway. METHODS Liver fibrosis mice models were established by intraperitoneal injection of CCL4. Hematoxylin and eosin (HE) staining was used to detect the structural and morphological changes of the liver. Masson staining was used to detect collagen deposition. Human hepatic stellate cells (HSCs, LX-2) were transfected with miR-140-5p mimic or inhibitor then treated with TGF-β1. The qRT-PCR and Western blotting was used to detect the expression of related molecules. The luciferase reporter assay was used to identify the target of miR-140-5p. RESULTS Our results indicated that miR-140-5p expression was downregulated in fibrotic liver tissues of model mice and LX-2 cells treated with TGF-β1. The overexpression of miR-140-5p decreased the expression of collagen1(COL1) and α-smooth muscle actin(α-SMA), inhibited the phosphorylation of Smad-2/3 (pSmad-2/3) in LX-2 cells. Conversely, the knockdown of miR-140-5p upregulated COL1 and α-SMA expression, increased Smad-2/3 phosphorylation. A dual-luciferase reporter assay showed that TGFβR1 was a target gene of miR-140-5p. The overexpression of miR-140-5p suppressed TGFβR1 expression in LX-2 cells. Additionally, knockdown of TGFβR1 decreased the expression of COL1 and α-SMA. Conversely, the overexpression of TGFβR1 reversed the inhibitory effect of miR-140-5p upregulation on expression of COL1 and α-SMA. CONCLUSION miR-140-5p bound to TGFβR1 mRNA 3'-untranslated region(3'UTR) and inhibited the expression of TGFβR1, pSmad-2/3, COL1 and α-SMA, thereby exerting a potential therapeutic effect on hepatic fibrosis.

Abstract
BACKGROUND AND AIMS Age-related loss of skeletal muscle mass and strength begins at 40 years of age, and limited evidence suggests that niacin supplementation increases levels of nicotinamide adenine dinucleotide in mouse muscle tissue. In addition, skeletal muscle has a key role in the body's processing of glucose. Therefore, this study aimed to investigate the relationship between dietary niacin and skeletal muscle mass, strength, and glucose homeostasis in people aged 40 years and older. METHODS This study was an American population-based cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES). Considering that some outcomes are only measured in specific survey cycles and subsamples, we established three data sets: a grip strength dataset (2011-2014, n=3772), a body mass components dataset (2011-2018, n=3279), and a glucose homeostasis dataset (1999-2018, n=9189). Dietary niacin and covariates were measured in all survey cycles. Linear regression or logistic regression models that adjusted for several main covariates, such as physical activity and diet, was used to evaluate the relationship between dietary niacin and grip strength, total lean mass, appendicular lean mass, total fat, trunk fat, total bone mineral content, homeostasis model assessment of insulin resistance (HOMA-IR), fasting blood glycose, fasting insulin and sarcopenia risk. Subgroup analyses, a trend test, an interaction test, and a restricted cubic spline were used for further exploration. RESULTS Higher dietary niacin intake was significantly correlated with higher grip strength (β 0.275, 95% confidence intervals [CI] 0.192-0.357), higher total lean mass (β 0.060, 95% CI 0.045-0.074), higher appendicular lean mass (β 0.025, 95% CI 0.018-0.033), and higher total bone mineral content (β 0.005, 95% CI 0.004-0.007). By contrast, higher dietary niacin intake was significantly associated with lower total fat (β -0.061, 95% CI -0.076 to -0.046), lower trunk fat (β -0.041, 95% CI -0.050 to -0.032) and lower sarcopenia risk (OR 0.460, 95% CI 0.233 to 0.907). In addition, dietary niacin significantly reduced HOMA-IR, fasting blood glucose (in participants without diabetes), and fasting insulin (p <0.05). CONCLUSION Niacin is associated with improved body composition (characterized by increased muscle mass and decreased fat content) and improved glucose homeostasis in dietary doses. Dietary niacin supplementation is a feasible way to alleviate age-related muscular loss.

Abstract
This study aimed to explore the consistency of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-3 (IGFBP-3) by detecting peripheral whole blood and venous serum among children. As a cross-sectional study, children who were aged 0-14 as well as received physical examinations in the Child Healthcare Department of the Children's Hospital of Nanjing Medical University during January 2022 to April 2022 were enrolled in this study. Meanwhile, both of peripheral whole blood and venous serum samples were collected, and the levels of IGF-1 and IGFBP-3 were assayed individually via chemiluminescence immunoassay (CLIA). Additionally, linear regression equation was used to analyze the correlation of results between two categories of samples, while Inter-class Correlation Coefficient (ICC) was used to evaluate the consistency of test results among two types of samples. The change trends of IGF-1 and IGFBP-3 with age were analyzed at the same time. A total of 203 valid matched samples were collected, including 117 boys and 86 girls. Peripheral whole blood was well correlated with serum IGF-1 (r=0.986, P<0.001) and IGFBP-3 (r=0.974, P<0.001), and the linear regression equation is shown as follows: (IGF-1) venous serum =1.047×(IGF-1) peripheral whole blood-6.840; (IGFBP-3) venous serum=0.924×(IGFBP-3) peripheral whole blood+0.396. The correlation and consistency were still persisted after being stratified by sex and age. ICC of IGF-1 and IGFBP-3 were 0.983 and 0.967, respectively which provided an excellent strength of agreement. The levels of IGF-1 or IGFBP-3 in boys' and girls' peripheral whole blood and serum showed significant statistical differences among various age groups (all P<0.001), and also increased significantly with age (all P trend<0.001). In conclusion, the results of IGF-1 and IGFBP-3 in peripheral whole blood and venous serum had positive comparability that could be mutually recognized. The detection of IGF-1 and IGFBP-3 in peripheral whole blood had great potential for young age children by providing guidance for nutritional intervention, growth and development assessment.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide. Our previous studies have found that Shuangyu Tiaozhi Decoction (SYTZD) could produce an improvement in NAFLD-related indicators, but the underlying mechanism associated with this improvement remains unclear. The study aimed to investigate the potential mechanism of SYTZD against NAFLD through network pharmacology and experimental verification. The components of SYTZD and SYTZD drug containing serum were analyzed using ultra-performance liquid chromatography to quadrupole/time-of-flight mass spectrometry (UPLC-Q/TOF-MS). Active components and targets of SYTZD were screened by the traditional Chinese medical systems pharmacology (TCMSP) and encyclopedia of traditional Chinese medicine (ETCM) databases. NAFLD-related targets were collected from the GeneCards and DisGeNET databases. The component-disease targets were mapped to identify the common targets of SYTZD against NAFLD. Protein-protein interaction (PPI) network of the common targets was constructed for selecting the core targets. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the core targets was performed using the database for annotation, visualization, and integrated discovery (DAVID) database. Furthermore, animal and cell models were constructed for validating the predictions of network pharmacology. Lipid accumulation, liver histopathology, insulin resistance, and core gene expression were measured by oil red O staining, hematoxylin and eosin staining, insulin tolerance test, real-time quantitative polymerase chain reaction, and Western blotting, respectively. Two components and 22 targets of SYTZD against NAFLD were identified by UPLC-Q/TOF-MS and relevant databases. PPI analysis found that ESR1, FASN, mTOR, HIF-1α, VEGFA, and GSK-3β might be the core targets of SYTZD against NAFLD, which were mainly enriched in the thyroid hormone pathway, insulin resistance pathway, HIF-1 pathway, mTOR pathway, and AMPK pathway. Experimental results revealed that SYTZD might exert multiple anti-NAFLD mechanisms, including improvements in lipid deposition, inflammation, and insulin resistance. SYTZD treatment led to decreases in the lipid profiles, hepatic enzyme levels, inflammatory cytokines, and homeostatic model assessment for insulin resistance (HOMA-IR). SYTZD treatment affected relative mRNA and protein levels associated with various pathways. Our findings reveal that SYTZD could alleviate NAFLD through a multi-component, multi-target, and multi-pathway mechanism of action.

Abstract
We propose a kind of fast and high-precision alignment algorithm based on the ESO technology. Firstly, in order to solve the problems of rapid, high-accuracy, and anti-interference alignment on the moving pedestal in the north-seeker, the ESO technology in control theory is introduced to improve the traditional Kalman fine-alignment model. This method includes two stages: the coarse alignment in the inertial frame and fine alignment based on the ESO technology. By utilizing the ESO technology, the convergence speed of the heading angle can be greatly accelerated. The advantages of this method are high-accuracy, fast-convergence, strong ability of anti-interference, and short time-cost (no need of KF recursive calculation). Then, the algorithm model, calculation process, and the setting initial-values of the filter are shown. Finally, taking the shipborne north-finder based on the FOG (fiber-optic gyroscope) as the investigated subject, the test on the moving ship is carried out. The results of first off-line simulation show that the misalignment angle of the heading angle of the proposed (traditional) method is ≤2.1' (1.8') after 5.5 (10) minutes of alignment. The results of second off-line simulation indicate that the misalignment angle of the heading angle of the proposed (traditional) method is ≤4.8' (14.2') after 5.5 (10) minutes of alignment. The simulations are based on the ship-running experimental data. The measurement precisions of Doppler velocity log (DVL) are different in these two experiments.

Abstract
In degraded karst ecosystem, vegetation restoration efforts almost exclusively rely on planted seedlings, but this is not effective to maintain community diversity and resilience. As seed functional traits, seed dormancy and germination are key to community assembly. Unfortunately, these elements are commonly overlooked in restoring degraded ecosystems. This work classifies seed dormancy of 27 species with different life forms that are common on a degraded karst mountain. We examined the effects of temperature regime and light conditions on percentage germination and assessed the relationships between seed traits and germination index using a partial least squares regression (PLSR). Approximately 48% of the investigated species had physiological dormancy, 37% were non-dormant, 7% had morphophysiological dormancy, 4% had morphological dormancy and 4% had physical dormancy. We found that 94% (15 out of 16) species had maximum germination in warm temperature regimes (20/13 and 25/18 °C), while the remaining species required cool temperatures (10/4 °C). PLSR analysis indicated a significant positive correlation between seed mass and T50m (time to 50% final germination), and a negative correlation between seed moisture content and percentage germination. Our findings indicate that seed traits are important factors in seed-based restoration practice. F. esculentum, O. opipara, P. fortuneana and S. salicifolia are recommended for direct seeding during the early rainy season to restore seriously degraded lands in subtropical karst regions.

Abstract
Dirac semimetals have attracted a great deal of current interests due to their potential applications in topological quantum computing, low-energy electronic devices, and single photon detection in the microwave frequency range. Herein are results from analyzing the low magnetic (B) field weak-antilocalization behaviors in a Dirac semimetal Cd3As2thin flake device. At high temperatures, the phase coherence lengthlϕfirst increases with decreasing temperature (T) and follows a power law dependence oflϕ∝T-0.4. Below ∼3 K,lϕtends to saturate to a value of ∼180 nm. Another fitting parameterα, which is associated with independent transport channels, displays a logarithmic temperature dependence forT > 3 K, but also tends to saturate below ∼3 K. The saturation value, ∼1.45, is very close to 1.5, indicating three independent electron transport channels, which we interpret as due to decoupling of both the top and bottom surfaces as well as the bulk. This result, to our knowledge, provides first evidence that the surfaces and bulk states can become decoupled in electronic transport in Dirac semimetal Cd3As2.

Abstract
BackgroundCalcium/Calmodulin-dependent protein kinase IV (CaMK4) is a serine kinase expressed in CD4 T cells whom activity is increased in patients with active systemic lupus erythematosus (SLE). We have shown that CaMK4 negatively impacts T regulatory (Treg) cells differentiation and function in SLE, but the underlying mechanism remains unclear. Recent, data suggest that CaMK4 impacts cellular metabolism.ObjectivesInvestigate how CaMK4 impacts Treg cell metabolism and its potential effect on Treg cell function.MethodsWe harvested CD62L+CD4+ T cells from wild-type (WT) or Camk4-/- mice and differentiated them in vitro into Treg (iTreg) cells. We assessed iTreg metabolism using Seahorse XF analyzer and mass spectrometry (metabolomics). Gene expression was assessed at the mRNA (RT-qPCR) and at the protein level (Western Blot). Phosphofructokinase activity was assessed by a colorimetric assay (Abcam). In vitro gene knockdown was conducted by transfecting a guide RNA (gRNA) in CRISPR/Cas9-expressing T cells. Treg cell function was evaluated by in vitro immunosuppressive assay and in vivo by the adoptive transfer of T conventional T and iTreg cells (8:1 ratio) in Rag1-/- mice to induce inflammatory colitis. The relevance of CaMK4 in SLE was evaluated in vivo using a T-cell specific knockdown of CaMK4 in the B6.lpr mouse model, and in humans by culturing SLE patient T cells with KN-93, a CaMK4 specific inhibitor.ResultsiTreg cells from Camk4-/- mice had decreased glycolysis and increased mitochondrial metabolism compared to WT mice. Metabolomics studies suggested decreased activity of the rate-limiting glycolysis enzyme phosphofructokinase platelet-type (PFKP). While PFKP mRNA and protein levels were similar between WT and Camk4-/- iTreg, we found that PFKP activity was significantly decreased in Camk4-/- iTreg, suggesting post-transcriptional control of PFKP activity. Mechanistically, immunoprecipitation experiments confirmed that CaMK4 interacted with PFKP, and phosphoproteomic study suggested that CaMK4 phosphorylated serine residue 539 of PFKP, a site known to control PFKP activity. Excitingly, PFKP’s endproduct fructose 1,6-biphosphate negatively regulates the activation of the mitochondrial metabolism masterswitch AMPK, therefore linking decreased PFKP activity/glycolysis with increased mitochondrial metabolism in Camk4-/- Treg. To confirm the importance of PFKP in Treg biology, we confirmed that PFKP knockdown significantly improved iTreg function in vitro (p < 0.01) and in vivo using an adoptive CD4+ T cell transfer in to Rag1-/- mice (colitis model). Interestingly, iTreg lacking PFKP were transferred Rag1-/- mice were less likely to lose FoxP3 expression and to produce IL-17A, demonstrating higher Treg stability in an inflammatory environment. On a translational basis, lupus-prone B6.lpr mice with a T-cell specific CaMK4 knockdown displayed significantly less lupus manifestations. In human SLE, CD4+ T cells had higher PFKP activity compared to healthy donors, and PFKP activity correlated with the SLE disease activity index (SLEDAI, r= 0.47; p <0.05). Finally, culture of SLE CD4+ T cells with KN-93 led to a significant decrease in PFKP activity (p < 0.001).ConclusionIncreased CaMK4 activity in human SLE mediates Treg dysfunction and instability by altering PFKP activity. Restoring normal Treg metabolism by inhibition of CaMK4 or its downstream target PFKP represents a novel strategy for the treatment of SLE.AcknowledgementsMarc Scherlinger is financially supported by the Societe Françaises de Rhumatologie (SFR), Philippe, Monahan & Arthurs Sachs foundations.Disclosure of InterestsNone declared

With the current formula, the Hubbard–Stratonovich transformation is not necessary, accordingly the determinant calculation is not needed, which can improve the computational efficiency. The results show that, the simulation time has the square-law scaling with system sizes, which is comparable with the usual first-principles calculations. The current formula also improves the accuracy of the Suzuki–Trotter decomposition. As an example, we have studied the one-dimensional half-filled Hubbard model at finite temperature. The obtained results are in excellent agreement with the known solutions. The new formula and Monte Carlo algorithm could be applied to various studies in future.

Abstract
Objective: To explore accurate prenatal diagnosis, full-coverage graded counseling and follow-up for the fetus with cardiac birth defects (CBD). Methods: CBD fetus diagnosed prenatal by echocardiography from January 2018 to December 2020 in Guangdong Provincial People's Hospital were enrolled. Fetal CBD was graded (Ⅰ-Ⅵ) according to prognosis and possible operation time after birth, and the classification criteria and common diseases included were proposed. After the prenatal grading counseling, the outcome of the fetus was followed-up. The induced labor rate, live birth rate, prenatal and postnatal ultrasound diagnosis coincidence rate and other indicators were calculated. The disease composition ratio, prognosis of fetus with different grades and the outcome of integrated treatment were analyzed. Results: The detection rate of fetal CBD was up to 16.2% (1 971/12 188), 30 cases of which were excluded. A total of 1 941 cases were included in this study, including 196 cases (10.1%) of gradeⅠ, 433 cases (22.3%) of gradeⅡ, 615 cases (31.7%) of grade Ⅲ, 261 cases (13.4%) of grade Ⅳ, 388 cases (20.0%) of gradeⅤ, 48 cases (2.5%) of grade Ⅵ. Grade Ⅱ and gradeⅢ (the operation time was within 1 year after birth) accounted for 54.0% (1 048/1 941). The distribution of some diseases in different grades had obvious proportion advantage, which was representative. Among 1 747 CBD fetus, 736 cases (induced labor rate 42.1%) chose to terminate pregnancy due to CBD. Of the 1 010 live births, 975 cases (96.5%) had the same prenatal and postnatal diagnosis, 3 cases were missed diagnosis and 32 cases were misdiagnosed. The diagnostic accuracy of live births with severe and complex congenital heart disease was 383 out of 389 (98.5%). A total of 258 cases have received surgery or intervention. The age at the time of surgery or intervention was different among grades(χ²=47.3,P<0.001). With the improvement of prognosis from gradeⅠ to Ⅴ, the live birth rate increased and the induced labor rate decreased accordingly; the difference between grades was significant(χ²=623.6,P<0.001). Conclusions: Prenatal diagnosis and graded counseling is important in the integrated model. Fetal CBD grading could refine post-natal treatment strategies, guide delivery decisions and become an evaluation standard.

Abstract
Background To study the effect of the “Internet + Smart Bed” health management system (IPBS) established with ballistocardiography (BCG) technology on the quality of life of elderly patients with chronic diseases. Methods A total of 150 users with chronic diseases who had been staying in a nursing home during the period from January 2020 to March 2021 were enrolled and divided into 2 groups for experiments. The t-test and Bayesian methods were used to establish a generalized linear regression model to evaluate the effect of the IPBS on the quality of life of the subjects in the experiment. The control group (n=71) received routine examination and daily health risk management in pension facilities. Health service workers provided daily door-to-door care, and the users received regular diet, exercise, and medication supervision and guidance. The intervention group (n=79) was composed of users with chronic diseases, who accepted the IPBS. The health service workers, in addition to implementing routine examination and health risk management, conducted continuous monitoring and intervention management of the users’ vital signs by means of the IPBS. Results The results obtained with the Bayesian generalized linear regression model tended to agree with those of the t-test analysis. After 15 months of follow-up in the intervention group, the rates of body function, emotion, behavior compliance (BC), and health knowledge (HK) awareness were 1.47 times, 1.75 times, 1.53 times, and 1.69 times higher than those in the control group, respectively. In the intervention group, after using the IPBS, all scores of quality of life were better than those before use, and the differences were statistically significant P=0 or P=0.1 (P<0.05). In the control group, there were no statistically significant differences before and after observation (P>0.05). Conclusions Routine management in elderly users with chronic diseases by means of the IPBS, which could change the users’ bad living habits and eating habits, raise the patients’ HK awareness, and comprehensively improve the quality of life of patients with chronic diseases, is a self-health management model worthy of application and promotion.

Abstract
OBJECTIVES The study aimed to evaluate the association of dietary iron intake with incident dementia and brain iron deposition. DESIGN/SETTING/PARTICIPANTS We included dementia-free participants from the UK Biobank who completed at least one 24-hour dietary recall at study baseline (2009-2012) and were followed up to 2021. Incident dementia was determined through linkage to medical records and death registries. Brain MRI was conducted in a subgroup of participants since 2014, with T2* measurements being used as indicators of brain iron deposition. MEASUREMENTS Cox proportional hazard models were used to assess the associations of high (top quintile) and low (bottom quintile) versus medium (quintile 2 to 4) level of dietary iron intake with incident dementia, respectively. Linear regression was applied to assess the relations between dietary iron intake and brain T2* measurements. RESULTS During follow-up (mean = 9.5 years), a total of 1,454 participants (650 women and 804 men) developed dementia among 191,694 participants (55.0% female; mean age, 56.2 years). When adjusted for sociodemographic, lifestyle, and other dietary factors, participants with low dietary iron intake (< 10.05 mg/day) had a significantly higher dementia risk (hazard ratio [HR], 1.50, 95% confidence interval [CI], 1.19-1.89), while the relation for high intake (> 16.92 mg/day) was non-significant (HR, 1.16, 95% CI, 0.92-1.46). A significant gender difference (P-interaction < 0.001) was observed, with a U-shaped association in male participants (HR for low vs. medium, 1.56, 95% CI, 1.14-2.13; HR for high vs. medium, 1.39, 95% CI, 1.03 - 1.88; P-nonlinearity < 0.001) and no significant association in females, regardless of their menopause status. In general, dietary iron intake was not related to T2* measurements of iron deposition in most brain regions. CONCLUSION Our findings suggested a U-shape relationship between dietary iron intake and risk of dementia among males, but not females.

Abstract
Objective: To investigate the effects of combination treatment of photodynamic therapy (PDT) based on photosensitizer chlorin e6 (Ce6) and antibiotic agent tinidazole (TNZ) against periodontitis both in vitro and in vivo. Methods: The Sprague-Dewley (SD) rat periodontitis model was constructed using the method of orthodontic wire ligation. After successful modeling, SD rats were randomly divided into the following 6 groups (3 rats in each group): positive control (Ctrl+), Ce6, TNZ, a mixture of Ce6 and TNZ (Ce6/TNZ), Ce6 with laser irradiation (Ce6+L), a mixture of Ce6 and TNZ with laser irradiation (Ce6/TNZ+L). Methyl thiazolyl tetrazolium (MTT) assay was used to assess the cytotoxic activities of Ce6 (concentration range: 0-20 mg/L), TNZ (concentration range: 0-16.6 mg/L) and their mixture (Ce6/TNZ) in mouse fibroblast L929 cells. Fluorescence probe method was applied to measure the production of reactive oxygen species in the dental plaque biofilms after various treatments with and without 5-minute laser irradiation at 635 nm at a power density of 0.5 W/cm2 (Ce6+L and Ce6/TNZ+L groups), thus to evaluate the PDT performances. Cell counting kit-8 (CCK-8) and live/dead staining were used to assess the antibacterial activity in each of the groups and the combination index (CI) of PDT combined with TNZ was calculated subsequently. Flow cytometry was utilized to detect the apoptosis-inducing effects of these treatments in macrophage RAW264.7 cells after processing with the apoptosis detection kit. The inhibitory effects of various treatments on the absorption of alveolar bone of SD rats were further evaluated in the periodontitis rats by using the micro-CT. Results: The survival rates of L929 cells in the preset concentration range were all above 90% in Ce6, TNZ and Ce6/TNZ groups. Upon laser irradiation, the plaque biofilms in Ce6 and Ce6/TNZ groups showed significant green fluorescence, indicating that large amounts of reactive oxygen species were triggered and generated significantly in the dental plaque biofilms. However, the survival rates of dental plaque microorganisms in 5 Ce6/TNZ concentrations were (85.4±5.5)%, (76.0±8.9)%, (61.7±0.6)%, (56.3±2.6)% and (43.5±0.6)% respectively, which were significantly lower than that in Ce6 only and TNZ only groups (P<0.01). The CI levle of each drug concentration group was less than 1.0, which showed a significant synergistic antibacterial efficiency. Stronger apoptotic activities were observed in Ce6+L and Ce6/TNZ+L groups compared with those in Ce6 only and Ce6/TNZ only groups (P<0.01). In periodontitis rats, Ce6/TNZ combined laser irradiation could effectively inhibit the absorption of alveolar bone. The alveolar bone volume and the ratio of bone volume and tissue volume were (1.49±0.07) mm3 and (47.08±0.71)%, respectively. The distances between cementoenamel junction to alveolar bone crest on buccal and palatal sites decreased to (2.13±0.07) mm and (1.94±0.10) mm respectively, showing a high inhibition efficiency. Conclusions: Ce6-mediated PDT combined with TNZ possessed notable synergistic effects against periodontitis, reflecting in the efficient antibacterial effect, the apoptosis-inducing action on macrophages, and the inhibitory efficacy on the alveolar bone absorption in vivo.

Abstract
The airborne fungus Aspergillus fumigatus poses a serious health threat to humans by causing numerous invasive infections and a notable mortality in humans, especially in immunocompromised patients. Mould-active azoles are the frontline therapeutics employed to treat aspergillosis. The global emergence of azole-resistant A. fumigatus isolates in clinic and environment, however, notoriously limits the therapeutic options of mould-active antifungals and potentially can be attributed to a mortality rate reaching up to 100 %. Although specific mutations in CYP 51A are the main cause of azole resistance, there is a new wave of azole-resistant isolates with wild-type CYP 51A genotype challenging the efficacy of the current diagnostic tools. Therefore, applications of whole-genome sequencing are increasingly gaining popularity to overcome such challenges. Prominent echinocandin tolerance, as well as liver and kidney toxicity posed by amphotericin B, necessitate a continuous quest for novel antifungal drugs to combat emerging azole-resistant A. fumigatus isolates. Animal models and the tools used for genetic engineering require further refinement to facilitate a better understanding about the resistance mechanisms, virulence, and immune reactions orchestrated against A. fumigatus. This review paper comprehensively discusses the current clinical challenges caused by A. fumigatus and provides insights on how to address them.

Abstract
OBJECTIVE To investigate the role of FKBP4 protein in cisplatin-induced premature ovarian insufficiency (POI). OBJECTIVE We performed ITRAQ assay of the ovarian tissues from 4 mice with cisplatin-induced POI and 4 control mice, and identified FKBP4 as a significantly down-regulated protein in the oocytes and granulosa cells following cisplatin treatment. TargetScan software was used for target analysis of FKBP4, and qRT-PCR and Western blotting were used to verify the expression levels of miR-483-5p and FKBP4 in the mouse models. Serum samples were collected from patients with POI and healthy women for detecting miR-483-5p level with qRT-PCR. Cell transfection and dual-luciferase assay were performed to determine the relationship between miR-483-5p and FKBP4. In primary granulosa cells and KGN cells, we examined the effect of miR-483-5p alone, miR-483-5p and cisplatin, and miR-483-5p combined with both cisplatin and FKBP4 on cell apoptosis. We also assessed ovarian function in a transgenic mouse model with ovarian miR-483-5p overexpression in comparison wigh wildtype mice using immunofluorescence assay, in situ hybridization and ELISA. OBJECTIVE Ovarian FKBP4 expression was significantly decreased in mice with cisplatin-induced POI. Analysis using TargetScan software indicated that FKBP4 was the potential target of miR-483-5p, which was highly expressed in the ovaries and serum of POI mice and in the serum of patients with POI. In vitro experiments further confirmed that FKBP4 was the target of miR-483-5p. In KGN and primary granulosa cells, FKBP4 overexpression significantly reduced cell apoptosis induced by both cisplatin and miR-483-5p overexpression (P= 0.0045 and 0.0177, respectively). In the transgenic mice with miR-483-5p overexpression in the oocytes, cisplatin induced more severe ovarian damages as compared with those in the wild-type mice. OBJECTIVE miR-483-5p/FKBP4 is a new and important pathway in cisplatin-induced POI, in which cisplatin increases ovarian miR- 483-5p expression to result in targeted downregulation of FKBP4. Up-regulation of miR-483-5p may increase ovarian sensitivity to cisplatin and cause severe ovarian dysfunction. Detection of serum miR-483-5p level may help to predict the occurrence and development of POI.

Abstract
OBJECTIVE This study aims to explore the role of microRNA-320c (miR-320c) in regulating biological behaviors of cervical cancer and the potential mechanism, thus providing experimental references for developing therapeutic target of cervical cancer. PATIENTS AND METHODS Differential expressions of miR-320c in cervical cancer samples and normal cervical tissues were determined. Potential association between miR-320c level and clinical characteristics of cervical cancer patients was analyzed. After overexpression of miR-320c, migratory potential changes in HeLa, and C33-A cells were examined. At last, target gene binding to miR-320c was predicted online and its involvement in the malignant development of cervical cancer was finally explored. RESULTS It was found that miR-320c was lowly expressed in cervical cancer tissues. Compared with cervical cancer patients with high expression of miR-320c, those with low expression had higher rates of lymphatic metastasis and distant metastasis. Besides, the overexpression of miR-320c markedly inhibited migratory potential in HeLa and C33-A cells. GABRP was verified to be the target gene binding to miR-320c. Notably, GABRP was able to reverse the role of miR-320c in regulating migratory potential in cervical cancer. CONCLUSIONS MiR-320c is capable of inhibiting migratory potential in cervical cancer by targeting GABRP, which may be utilized as a therapeutic target of cervical cancer.

Abstract
OBJECTIVE To investigate the effects of micro ribonucleic acid (miR)-808 on cardiomyocyte apoptosis and expressions of caspase-3 and caspase-9 in rats with myocardial infarction (MI) by regulating the transforming growth factor-β1 (TGF-β1) signaling pathway. MATERIALS AND METHODS A total of 24 specific pathogen-free female Sprague-Dawley rats were enrolled and randomly divided into normal group, model group, and miR-808 group, 8 rats in each group. In the model group and miR-808 group, MI model was prepared by ligation of the left anterior descending coronary artery in the rats. The miR-808 group was transfected with miR-808 lentivirus after the model was established. After one week of intervention, the expression of TGF-β1 was detected by reverse transcription-polymerase chain reaction (RT-PCR). The cardiac function of rats was determined by echocardiography. The myocardium of rats was observed by Masson staining. The cardiomyocyte apoptosis of rats was examined by TdT-mediated dUTP-biotin nick end labeling (TUNEL) method. The expression levels of caspase-3 and caspase-9 were detected by Western blotting. RESULTS The expression of TGF-β1 mRNA was higher in the model group than that in the normal group (p<0.05), but compared with that in the model group, it was lower in the miR-808 group. The myocardial function and cardiomyocyte survival rate in the miR-808 group was better and higher than those in the model group (p<0.05). The expression levels of caspase-3 and caspase-9 in the miR-808 group were lower than those in the model group (p<0.05). CONCLUSIONS MiR-808 can inhibit cardiomyocyte apoptosis in rats with MI by down-regulating TGF-β1 expression and inhibiting the expressions of caspase-3 and caspase-9.

Abstract
UNLABELLED This is the first study to report changes in BMD and related risk factors among Chinese patients with HIV after initiation of tenofovir disoproxil fumarate (TDF)-containing antiretroviral therapy. Greater bone mineral density (BMD) loss was observed in patients treated with TDF, compared to those on non-TDF-containing regimens. Our findings provide important knowledge regarding the risk factors in the long-term clinical management of patients with HIV in China. INTRODUCTION Persons living with HIV (PLWH) are at increased risk for osteoporosis and fracture. Tenofovir disoproxil fumarate (TDF) has been associated with higher rates of bone mineral density (BMD) loss, osteoporosis, and fracture. Few studies have studied the impact among PLWH in Asia. METHODS We analyzed retrospectively patients from the outpatient HIV clinic of a large tertiary hospital in Beijing, China, from March 2007 to May 2016. Patients who had dual-energy X-ray absorptiometry testing prior to antiretroviral initiation and at 48 and/or 96 weeks after initiation were included in this analysis. RESULTS A total of 136 patients were included (mean age 36.0 ± 10.6 years) and over 90% participants were male and Han Chinese ethnicity. We observed greater declines in BMD at the spine from baseline to week 48 (-2.94% vs. -0.74%) and at the hip from baseline to week 96 (-4.37% vs. -2.34%) in the TDF group compared with the non-TDF group. With regard to HIV-specific parameters, longer duration since HIV diagnosis and undetectable viral load over time were associated with lower BMD at the hip [relative risk (RR) 0.97, 95% confidence index (CI) (0.95, 0.99) per 1 year increase and RR 0.96, 95%CI (0.94, 0.99), respectively] and femoral neck [RR 0.97, 95%CI (0.95, 0.99) per 1 year increase and RR 0.97, 95%CI (0.95, 0.998), respectively] over 96 weeks. CONCLUSIONS This is the first study to report changes in BMD among PLWH after initiation of TDF-based antiretroviral therapy in China. Our findings provide important knowledge for the long-term clinical management of PLWH from this region.

Abstract
Background Perinatal and neonatal care for very low birth weight (VLBW) infants have changed significantly during the past two decades. However, it is unclear how these changes have affected neonatal mortality and morbidity in developing countries. Objectives The aim of this study was to investigate the impact of the advanced neonatal care on short-term outcomes of VLBW infants. Methods A retrospective study was performed to compare the mortality and morbidity of VLBW infants between period I (2007-2011) and period II (2012-2016) in our unit. Results A total of 188 infants in period I and 214 infants in period II were evaluated. The overall in-hospital mortality for VLBW infants dropped from 26.1% in period I to 13.1% in period II. The incidence of birth asphyxia decreased significantly during period II (10.1% [period I] vs 3.7% [period II]). The rate of nasal continuous positive airway pressure (NCPAP) use (69.8% vs 87.1%) and the duration of NCPAP therapy (median: 3 days [period I] vs 5 days [period II]) increased significantly, while the proportion of infants treated with mechanical ventilation and the duration of mechanical ventilation significantly decreased. There was a significant increase in the proportion of survivors without major neonatal morbidity, mainly due to a significant increase in the incidence of survival without bronchopulmonary dysplasia (BPD) (72.7% vs 82.8%). In contrast, the incidence of late-onset sepsis increased significantly during period II (7.9% vs 19.4%). Conclusions Active perinatal care is associated with improvements in survival and survival free of BPD for VLBW infants. However, late-onset sepsis is still a major concern.

Abstract
OBJECTIVE To investigate the effects of interleukin-6 (IL-6) gene knockout on myocardial remodeling after myocardial infarction (MI) in mice and the potential mechanism, to provide certain references for the prevention and treatment of MI in clinic. MATERIALS AND METHODS A total of 40 male C57 mice were divided into two groups, namely Sham group (n=20) and MI group (n=20), using a random number table. Another 20 mice with IL-6 gene knockout were enrolled into the MI + IL-6 KO group. The MI model was established by means of ligating the left anterior descending coronary artery of the mice. 28 d later, the survival status of the three groups of mice was recorded. In addition, the cardiac functions of each group of mice, including two-dimensional echocardiography, ejection fraction (EF%) and fractional shortening (FS%), were measured. The cross-sectional area and pathological change of the myocardial cells in cardiac tissues of each group of mice were detected via hematoxylin and eosin (H&E) staining. Immunohistochemistry was applied to determine the expression of tumor necrosis factor-alpha (TNF-α) in each group of mouse cardiac tissues. Moreover, immunofluorescent staining was utilized to measure the content of M2 macrophages in each group of mouse cardiac tissues. RESULTS The 28-d survival rate of the mice with IL-6 gene knockout was remarkably higher than that of the wild-type mice (p<0.05). Furthermore, the cardiac functions of the mice in the MI + IL-6 KO group were superior to those in the MI group, with markedly improved FS% and EF% (p<0.05). According to the H&E staining results, the cross-sectional areas of the heart and myocardial cells were decreased notably in MI + IL-6 KO group compared with those in the MI group (p<0.05). The immunohistochemical staining results showed that IL-6 knockout could lower the MI-induced high expression of TNF-α (p<0.05), and Masson's trichrome staining indicated that IL-6 knockout could also repress the degree of cardiac fibrosis. Moreover, it was discovered through immunofluorescent staining that the mice in the MI + IL-6 KO group had markedly elevated content of M2 macrophages in cardiac tissues than those in the MI group (p<0.05). CONCLUSIONS Inhibiting IL-6 gene expression can prominently ameliorate the MI-induced myocardial remodeling, whose mechanism is possibly associated with the activation of M2 macrophages and reduced collagen production in fibroblast cells.

Abstract
OBJECTIVE Multiple microRNAs (miRNAs) are abnormally expressed in endothelial cells during the occurrence of coronary artery disease (CAD). Previous researches have demonstrated that miRNA-26a-5p participates in regulating the proliferation of vascular smooth muscle cells and angiogenesis. The aim of this study was to clarify the role of miRNA-26a-5p in regulating cellular performances of endothelial cells in the progression of CAD. PATIENTS AND METHODS In vivo CAD model was successfully established by feeding high-fat diet in 8-week-old female ApoE/LDLR-/- mice. CAD mice were administered with miRNA-26a-5p NC or miRNA-26a-5p inhibitor, respectively. Meanwhile, coronary endothelial cells were isolated from CAD mice and normal controls. Relative levels of miRNA-26a-5p, the gene of phosphate and tension homology deleted on chromosome ten (PTEN) and vascular endothelial growth factor (VEGF) in CAD patients and coronary endothelial cells isolated from CAD mice were examined. The regulatory effect of miRNA-26a-5p on atherosclerosis-related genes in primary endothelial cells and HUVECs were detected as well. Moreover, the viability and apoptosis of primary endothelial cells with miRNA-26a-5p knockdown were assessed by cell counting kit-8 (CCK-8) assay and flow cytometry, respectively. Dual-luciferase reporter gene assay was conducted to identify the relationship between miRNA-26a-5p and PTEN. Furthermore, the regulatory role of miRNA-26a-5p in phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway was examined in endothelial cells. RESULTS MiRNA-26a-5p and VEGF were significantly downregulated in CAD patients and primary endothelial cells isolated from CAD mice. However, PTEN was significantly upregulated. CAD mice administrated with miRNA-26a-5p inhibitor exhibited remarkably upregulated ET-1, TxA2, and ANG II, as well as downregulated eNOS and PGI2. Conversely, transfection of miRNA-26a-5p mimics in HUVECs obtained the opposite trends. PTEN was identified as the direct target gene of miRNA-26a-5p. Moreover, significantly reduced viability and enhanced apoptotic rate were observed in endothelial cells isolated from CAD mice administrated with miRNA-26a-5p inhibitor. In addition, the protein level of p-AKT in endothelial cells with miRNA-26a-5p knockdown was significantly down-regulated. CONCLUSIONS MiRNA-26a-5p influences the proliferative and apoptotic abilities of endothelial cells isolated from CAD mice by targeting PTEN to activate PI3K/AKT pathway.

Abstract
OBJECTIVE Renal cancer represents about 3% of all human cancers. Clear cell renal cell carcinoma (ccRCC) is the main type of renal cancer. MicroRNAs (miRNAs) have been reported to play crucial roles in the carcinogenesis of human cancers. This study was aimed to investigate the expression of miR-1294 and the mechanisms underlying miR-1294-mediated ccRCC progression. MATERIALS AND METHODS The miR-1294 expression levels in ccRCC cell lines were analyzed by quantified real time-PCR (qRT-PCR). The effect of the miR-1294 expression on the overall survival of ccRCC patients was analyzed by the Kaplan-Meier Plotter. Cell proliferation, colony growth, and cell invasion were examined by cell counting kit-8 assay, colony formation assay, and transwell invasion assay, respectively. The luciferase activity reporter assay and Western blot assay were conducted to validate the connection between miR-1294 and homeobox A6 (HOXA6). RESULTS MiR-1294 was downregulated in ccRCC cell lines and correlated with the poor overall survival of ccRCC patients. The overexpression of miR-1294 inhibits ccRCC cell proliferation, colony growth, and cell invasion. HOXA6 was validated as a target of miR-1294 and negatively regulated by miR-1294. The overexpression of HOXA6 attenuated the miR-1294-mediated effects on ccRCC cellular functions. CONCLUSIONS Our results indicated that miR-1294 functions as a tumor suppressor in ccRCC. MiR-1294 suppressed cell proliferation, colony formation, and invasion in ccRCC partially via targeting HOXA6.

Abstract
Abstract
Background
Obesity is a pressing pandemic. However, major policies have targeted individual responsibility and focused on “losing weight or lowering calories”. Such approach has limited effect and overlooks the hidden obesity.
Methods
Under auspices of NHRI Forum, Taiwan; the WAKE.TAIWAN Research Team analyzed the global trends of policies, strategies, and literatures to formulate guiding principles for a total solution. 1. Defining obesity should go beyond body weight and emphasize more on healthy body composition and muscle mass, etc. 2. Effective obesity control strategy should facilitate building healthy living environments, lifestyle, and culture for natural flow of healthy behaviors. 3. All sectorial leaders should be involved in engaging and promoting healthy lifestyle culture and environment.
Results
”Guidelines for Establishing a lifestyle and Culture of Healthy Body Build” has been published as a blueprint for policy reform and strategies development, which consists of three parts. Part I emphasizes the active roles, social responsibilities, influence, and opportunities confronted the leaders and experts in all sectors and how government may facilitate these societal engagements, “Healthy by All”. The crucial sectors should include academia, NGO/NPO, industry/business, workplaces, healthcare systems, educational sectors, media and press, etc. Part II details on community spatial planning and architectural designs for healthy lifestyles. Part III proposes governmental “Health in All” infrastructure and mechanism.
Conclusions
We anticipate that the Guideline may draw out expertise and volunteering in all sectors of the society and help guide the public to take initiative in building such a culture of healthy-body-build and achieving this goal in all aspects of daily life.
Key messages
Emphasize on healthy body composition rather than body weight. Propagate 'Health by all' movement to foster building 'healthy physique' culture.

Abstract
For materials near the phase boundary between weak and strong topological insulators (TIs), their band topology depends on the band alignment, with the inverted (normal) band corresponding to the strong (weak) TI phase. Here, taking the anisotropic transition-metal pentatelluride ZrTe_{5} as an example, we show that the band inversion manifests itself as a second extremum (band gap) in the layer stacking direction, which can be probed experimentally via magnetoinfrared spectroscopy. Specifically, we find that the band anisotropy of ZrTe_{5} features a slow dispersion in the layer stacking direction, along with an additional set of optical transitions from a band gap next to the Brillouin zone center. Our work identifies ZrTe_{5} as a strong TI at liquid helium temperature and provides a new perspective in determining band inversion in layered topological materials.

Abstract
BACKGROUND A few epidemiological investigations and animal studies have demonstrated that bisphenol A (BPA) may affect female reproductive health. However, no epidemiologic study has investigated the relationship between BPA exposure and the risk of premature ovarian insufficiency (POI). METHODS In this case-control study, urinary concentrations of BPA and serum levels of reproductive hormone were measured. Associations between BPA concentrations and the risk of POI and POI-related hormone levels were estimated. RESULTS Among BPA quartiles, no obvious association was found between BPA levels and the risk of POI (p = 0.603). Although the adjusted odds ratio (OR) of POI was slightly increased for participants in the highest BPA concentration quartile, the association was not statistically significant (OR = 1.282, 95% confidence interval [CI] 0.615-2.049 for the highest vs. lowest quartile, p = 0.508). Although follicle stimulating hormone (FSH) and anti-Mullerian hormone (AMH) levels showed no tendency of an association with BPA (p = 0.941 and p = 0.876 for FSH and AMH, respectively), the highest quartile of luteinizing hormone was significantly positively associated with BPA levels (OR = 1.333, 95% CI 0.986-1.803, p = 0.042). CONCLUSIONS The urinary concentrations of BPA determined in this study were consistent with the range of exposure currently observed in Chinese women. However, BPA exposure at a relatively low level is not associated with POI in Chinese women. Further epidemiological studies are needed to confirm our findings.

Abstract
Early studies on the etiology and pathogenesis of hypertension have shown that it has a considerable association with inflammation and the immune response as well as periodontitis. Clinical studies have also shown that hypertension can promote the periodontal tissue destruction caused by periodontitis. However, the underlying mechanisms remain unclear. This study aimed to explore the possible mechanisms of how hypertension aggravates periodontitis. Treatment with or without the signal transducer and activator of transcription 1 (STAT1) inhibitor fludarabine was performed in an endothelial nitric oxide synthase gene knockout-related (Nos3-/-) mouse model with the hypertension phenotype of periodontitis induced by bacteria. Micro-computed tomography, immunohistochemistry, Western blot, quantitative reverse transcription polymerase chain reaction, immunofluorescence, and ELISA were performed. We demonstrated that Nos3-/--related hypertension increases bone resorption and periodontal destruction in periodontitis lesion areas, which can be inhibited by the STAT1 inhibitor. Experimental data also showed that Nos3-/- significantly increased macrophage infiltration and proinflammatory cytokine expression in the periodontitis lesion area, which is dependent on the angiotensin II-induced STAT1 pathway. Inhibition of STAT1 in vivo can decrease the expression of proinflammatory cytokines and macrophage infiltration. Furthermore, data in this study showed that Nos3-/--related hypertension further downregulated the STAT3 anti-inflammatory function and its downstream chemokine expression in a STAT1-dependent manner. By applying RAW 264.7 and L929 cell lines and monocytes isolated from Nos3-/- mice, we confirmed that activation of the STAT1 pathway inhibits STAT3 and its downstream pathway and promotes inflammatory cytokine expression in vitro. Collectively, our current study demonstrated that STAT1 plays an indispensable role in the Nos3-/--related hypertension with aggravation of periodontitis, suggesting that STAT1 may be a key target for the treatment of periodontitis with hypertension.

Abstract
We present in this paper the results from a recent study on the stability of the quantum Hall skyrmions state at a Landau level filling factor (ν) close to ν = 1 in a narrow GaAs quantum well. Consistent with previous work, a resonant behavior is observed in the resistively detected NMR measurements. In the subsequent current-voltage (I-V) measurements to examine its breakdown behavior under radio frequency radiations, we observe that the critical current assumes the largest value right at the 75As nuclear resonant frequency. We discuss possible origin for this unexpectedly enhanced stability.

Abstract
We report on detailed experimental studies of a high-quality heterojunction insulated-gate field-effect transistor (HIGFET) to probe the particle-hole symmetry of the fractional quantum Hall effect (FQHE) states about half-filling in the lowest Landau level. The HIGFET is specially designed to vary the density of a two-dimensional electronic system under constant magnetic fields. We find in our constant magnetic field, variable density measurements that the sequence of FQHE states at filling factors ν=1/3,2/5,3/7… and its particle-hole conjugate states at filling factors 1-ν=2/3,3/5,4/7… have a very similar energy gap. Moreover, a reflection symmetry can be established in the magnetoconductivities between the ν and 1-ν states about half-filling. Our results demonstrate that the FQHE states in the lowest Landau level are manifestly particle-hole symmetric.

Abstract
The size, shape and connectivity of oxide octahedra are essential for understanding and controlling the emergent functional properties of ABO3 perovskites. Using first-principles calculations, we systematically studied the oxygen octahedral rotation and deformation in LaAlO3/SrTiO3(001) superlattices. Superlattices with electron- or hole-doped interfaces, or both, are compared. The results showed that there are at least three different types of oxygen octahedral distortions in these superlattices, which is more than what had previously been reported in the literature. We demonstrate that interfacial oxygen octahedral coupling and hole-doping, in addition to epitaxial strain, are the key factors underlying the formation of multiple types of oxygen octahedral rotations in these systems. We confirm that oxygen octahedral rotations and deformations play an essential role in insulator-metal transitions. Furthermore, octahedral distortion leads to ferroelectricity like dipole formation with the polarization vector always pointing to the positively charged interfaces.

Abstract
Gut microbiota plays important roles in host nutrition, immunity, development and health; therefore, disruption of the gut microbiota is closely associated with development of diseases in the host. In amphibians, metamorphosis is associated not only with extensive changes in the gut microbiota, but also with high mortality. Therefore, we hypothesized that unsuccessful restructuring of the gut microbiota during metamorphosis was an important factor that caused the fatalities. To test this hypothesis, we investigated the gut microbiota of apparently sick and healthy giant spiny frog tadpoles during metamorphosis, using high-throughput sequencing of the 16S rRNA gene. Our results showed that most dominant phyla differed significantly among developmental stages of sick and healthy Paa spinosa tadpoles. The differences in the dominant genera in sick and healthy tadpoles were the highest at the stage of degeneration of cloacal tube (TDCT). After the metamorphosis, the composition of the gut microbiota was more alike between healthy and sick tadpoles at the stage of forelimb emergence than at TDCT. These results imply that failed restructuring of the gut microbiota during metamorphosis caused the death of P. spinosa tadpoles. These results provided an important reference to prevent the high actual of P. spinosa tadpoles during metamorphosis. SIGNIFICANCE AND IMPACT OF THE STUDY: We investigated the gut microbiota of apparently sick and healthy giant spiny frog (Paa spinosa) tadpoles during metamorphosis, using high-throughput sequencing of the 16S rRNA gene.

Abstract
Objective: To investigate the clinical outcomes of one-stage posterior correction surgery and second-stage anterior debridement and fusion in treating children with thoracic tuberculosis complicated with kyphoscoliosis. Methods: From January 2008 to December 2014, a total of 17 children with thoracic vertebral tuberculosis complicated with kyphoscoliosis who underwent a one-stage posterior correction and second-stage anterior debridement and complementary fusion were included. There were 8 males and 9 females with an average age of (8±4) years (5-14 years). All patients underwent posterior correction and anterior debridement and bone graft fusion surgery. The neurological function was determined by Frankel grade. The operation time, estimated blood loss (EBL), levels fused and numbers of screws were recorded. The following radiographic parameters were measured: Cobb angle of the coronal curve, regional kyphosis and sagittal vertical axis (SVA). The incidence of intraoperative and postoperative complications was recorded. The data before and after the operation were compared with paired sample t test. Results: The tuberculosis lesions located in the thoracic vertebrae, and the abscess involved 2 to 4 vertebral segments. The average operation time was (4.1±0.8) h, the EBL was (526±275) ml, the levels fused were 7.6±2.3, and 173 pedicle screws were placed. The preoperative coronal curve averaged 12.6°±6.2°, and it was corrected to 4.2°±1.9° postoperatively (t=4.628, P<0.01), the regional kyphosis was 67.2°±19.4°, and it was corrected to 15.7°±8.2° postoperatively (t=8.192, P<0.01). The SVA improved from (8.1±5.0) mm to (3.0±1.7) mm postoperatively. The mean duration of follow-up for all the patients were (38±11) months. At final follow-up, SVA was reduced to (2.4±2.0) mm and the other parameter kept stable. Thirteen patients had more than one grade improvement of Frankel grade. The VAS score for all patients improved from 4.7±2.8 to 2.2±0.5 postoperatively (t=3.973, P=0.01), and improved to 0.5±0.5 at final follow-up (t=-7.880, P<0.01). No recurrence of primary spinal tuberculosis was seen at final follow-up of all patients. Conclusions: One-stage posterior correction and second-stage anterior complementary debridement and fusion is an effective procedure for children with thoracic tuberculosis complicated with kyphoscoliosis. Significant postoperative deformity correction could be achieved with satisfactory improvement of neurological function. Solid fusion and satisfactory correction maintenance were observed at mid-to long-term follow-up.

Abstract
Abstract
Objective
A new technique has been devised to treat mitral regurgitation (MR) through the transapical route by replicating the edge-to-edge repair surgery. This system encompasses an easy-to-use leaflet clamp and a smaller-sized delivery system (14F–16F). We aimed to evaluate the effectiveness of this device in a porcine model of acute MR.
Methods
Acute MR was induced in 36 anesthetized porcine subjects by severing the major chordae supporting the corresponding segment of the leaflet. This device was then transapically implanted on the prolapsing segment under 3D epicardial echocardiographic guidance. All of the animals were killed 30 days after the procedure to verify the proper location of the implanted devices.
Results
Cutting the major chordae induced an eccentric MR jet (MR grade: 3+, 27.8%/4+, 72.2%) in all of the animals. Every single pig was then successfully implanted with one clamp. The duration of catheterization ranged from 18 to 40 minutes. Overt MR reduction was observed following the procedure through echocardiography; residual MR was mild in 8 cases, trivial in 19 cases, and absent in 9 cases. In terms of hemodynamic parameters, the mean and maximum mitral valve pressure gradients were increased significantly (p<0.01), but these values were less than 4 mmHg in all of the cases. Autopsy demonstrated that all but one device were precisely placed to clip the prolapsing segment of the mitral valve, and there was no evidence of thrombosis, thromboembolism or impairment of the cardiac structure.

Conclusions
Transapical implantation of the novel mitral valve repair device is effective and safe in reducing acutely induced MR in pigs; thus, suggesting that it has great potential for clinical benefit in patients with MR.
