Abstract
OBJECTIVE To assess the clinical applicability of a semi-quantitative luciferase immunosorbent assay (LISA) for detecting antibodies against Treponema pallidum antigens TP0171 (TP15), TP0435 (TP17), and TP0574 (TP47) in diagnosing and monitoring syphilis. METHOD LISA for detection of anti-TP15, TP17, and TP47 antibodies was developed and evaluated for syphilis diagnosis using 261 serum samples (161 syphilis, 100 non-syphilis). 90 serial serum samples from six syphilis rabbit models (three treated, three untreated) and 110 paired serum samples from 55 syphilis patients were used to assess treatment effects by utilizing TRUST as reference. RESULTS Compared to TPPA, LISA-TP15, LISA-TP17, and LISA-TP47 showed sensitivity of 91.9%, 96.9%, and 98.8%, specificity of 99%, 99%, and 98%, and AUC of 0.971, 0.992, and 0.995, respectively, in diagnosing syphilis. Strong correlations (rs = 0.89-0.93) with TPPA were observed. In serial serum samples from rabbit models, significant difference in the relative light unit (RLU) were observed between the treatment and control group for LISA-TP17 (days 31-51) and LISA-TP47 (days 41). In paired serum samples form syphilis patients, TRUST titers and the RLU of LISA-TP15, LISA-TP17, and LISA-TP47 decreased post treatment (P < 0.001). When TRUST titers decreased by 0, 2, 4, or ≥8-folds, the RLU decreased by 17.53%, 31.34%, 48.62%, and 72.79% for LISA-TP15; 8.84%, 17.00%, 28.37%, and 50.57% for LISA-TP17; 22.25%, 29.79%, 51.75%, and 70.28% for LISA-TP47, respectively. CONCLUSION Semi-quantitative LISA performs well for syphilis diagnosis while LISA-TP17 is more effective for monitoring syphilis treatment in rabbit models and clinical patients.

Abstract
OBJECTIVES The aims of this study were to describe the national distribution of depressive symptoms in Chinese children and adolescents, to examine the determinants of depressive symptoms at individual, school and province levels and to assess the gender and age differences in the effect of school factors on depressive symptoms. STUDY DESIGN This was a national cross-sectional study. METHODS A school-based online survey was conducted in mainland China from between December 1, 2021, and January 1, 2022. A total of 398,520 eligible participants were included in the analysis. School-level data were drawn from students, headteachers and Baidu Maps, and province-level data were obtained from the national human development report. The Patient Health Questionnaire-2 was used to measure depressive symptoms. RESULTS Areas with the highest mean scores for depressive symptoms were in the northeastern, inner central and southwestern regions of China. At the individual level, younger age, male sex, being an only child, Han ethnicity, lower body mass index, more days of exercise, less drinking and smoking behaviours, higher subjective family socio-economic status (SES) and popularity in school were related to fewer depressive symptoms; however, objective family SES and maternal education were not related to fewer depressive symptoms. The school-level variables of public status, psychological activities and psychological courses and province-level variable of higher Human Development Index were associated with fewer depressive symptoms. The effect of psychological courses and activities on depressive symptoms was greater in females. CONCLUSIONS The results showed multilevel factors related to depressive symptoms and emphasised the importance of implementing school-based psychological activities to ameliorate depressive symptoms in Chinese children and adolescents across age and gender.

Abstract
OBJECTIVES Although infection rates may increase after relaxation of the zero COVID strategy, the extensive vaccination campaign in China could potentially curb the spread of COVID-19, which may be associated with a low level of risk perception and post-traumatic stress symptoms (PTSS). However, the relationship between vaccination, risk perception and PTSS has not been studied extensively. This study aims to examine the associations between the number of COVID-19 vaccine doses, consistency in the type of each dose and time since vaccination with PTSS, and the mediating role of risk perception on such relationships in China. STUDY DESIGN Cross-sectional sampling with a self-report questionnaire was used to measure vaccination, PTSS and risk perception. METHODS The survey was conducted in Beijing, China, from 13 January to 9 February 2023. Linear regression analyses were conducted to test the relationship between vaccination, risk perception and PTSS. RESULTS The analysis included 55,803 individuals. In total, 72.86 % of participants received two doses of the COVID-19 vaccine. Regression results indicated that people with two doses of the COVID-19 vaccine had a lower level of PTSS (β = -1.232, 95 % confidence interval [CI]: -1.930, -0.534) than those who had not received any doses of the COVID-19 vaccine. Only the negative relationship between two-dose vaccination and PTSS was mediated by risk perception, while the negative relationship between the time since vaccination and PTSS was suppressed by risk perception. CONCLUSIONS This study showed that receiving the COVID-19 vaccine reduced PTSS by decreasing perceived risk. Vaccination time was negatively associated with PTSS, but this relationship was suppressed by risk perception.

Abstract
The purpose of this study is to investigate heart-fatty acid binding protein (H-FABP) leakage from cardiomyocytes as a quantitative measure of cell membrane damage and to test healing by Resolvin E1 (RVE1) as a potential therapeutic for patients with inflammatory diseases (cardiovascular disease and comorbidities) with high morbidity and mortality. Our quantitative ELISA assays demonstrated H-FABP as a sensitive and reliable biomarker for measuring cardiomyocyte damage induced by lipopolysaccharide (LPS) and healing by RvE1, a specialized pro-resolving mediator (SPM) derived from the Omega-3 fatty acid, eicosapentaenoic acid (EPA), a dietary nutrient that balances inflammation to restore homeostasis. RvE1 reduced leakage of H-FABP by up to 86%, which supports our hypothesis that inflammation as a mechanism of injury can be targeted for therapy. H-FABP as a blood biomarker was tested in 40 patients admitted to Boston Medical Center for respiratory distress, (20 patients with and 20 patients without COVID infection). High levels of H-FABP correlated with clinically diagnosed CVD, diabetes, and end-stage renal disease (ESRD) in both patient groups. The level of H-FABP indicates not only CVD damage but is a valuable measure for patients with increased inflammation disease comorbidities.

Abstract
PURPOSE/OBJECTIVE(S) The risk of temporal lobe injury (TLI) in recurrent nasopharyngeal carcinoma (rNPC) patients with intensity-modulated radiation therapy (IMRT) is high. We aimed to construct the normal tissue complication probability (NTCP) model for TLI of rNPC and establish a risk predictive model. MATERIALS/METHODS We retrospectively analyzed 103 patients with rNPC who had received two courses of IMRT in our institution. The 206 temporal lobes (TLs) of these patients were randomly divided into a training (n = 144) and validation group (n = 62). We determined the mean value of the following parameters to construct the Lyman NTCP model: TD50(1) (the dose with a 50% probability of complications to an organ when all volumes are irradiated), m [steepness of the dose-response at TD50(1)], and n (the parameter related to volume effect). The most predictive dosimetric parameter and clinical variables were integrated in Cox proportional hazards models. A nomogram was developed for predicting risk of TLs. RESULTS The parameters of the fitted NTCP model were TD50(1) = 107.84 Gy (95% confidence interval (CI), [97.15, 118.54]), m = 0.16 (95% CI, [0.14, 0.19]), and n = 0.04 (95% CI, [0.01, 0.06]). The cumulative dose delivered to 0.1 cm3 of temporal lobe volume (D0.1cc-c) was the most predictive dosimetric parameter for TLI. The Kaplan-Meier curves showed a significant difference in 2-year TLI-free survival among different risk groups according to the total score of nomograms. CONCLUSION The TD50(1) of TLI in patients with rNPC is 107.84 Gy in Lyman NTCP model. The nomogram model can accurately predict the risk of TLI for individual.

Abstract
Transaldolase deficiency predisposes to chronic liver disease progressing from cirrhosis to hepatocellular carcinoma (HCC). Transition from cirrhosis to hepatocarcinogenesis depends on mitochondrial oxidative stress, as controlled by cytosolic aldose metabolism through the pentose phosphate pathway (PPP). Progression to HCC is critically dependent on NADPH depletion and polyol buildup by aldose reductase (AR), while this enzyme protects from carbon trapping in the PPP and growth restriction in TAL deficiency. Although AR inactivation blocked susceptibility to hepatocarcinogenesis, it enhanced growth restriction, carbon trapping in the non-oxidative branch of the PPP and failed to reverse the depletion of glucose 6-phosphate (G6P) and liver cirrhosis. Here, we show that inactivation of the TAL-AR axis results in metabolic stress characterized by reduced mitophagy, enhanced overall autophagy, activation of the mechanistic target of rapamycin (mTOR), diminished glycosylation and secretion of paraoxonase 1 (PON1), production of antiphospholipid autoantibodies (aPL), loss of CD161+ NK cells, and expansion of CD38+ Ito cells, which are responsive to treatment with rapamycin in vivo. The present study thus identifies glycosylation and secretion of PON1 and aPL production as mTOR-dependent regulatory checkpoints of autoimmunity underlying liver cirrhosis in TAL deficiency.

Abstract
Objective: To investigate the therapeutic effect and mechanism of lenvatinib on regorafenib-resistant hepatocellular carcinoma cells. Methods: CCK-8 and clone formation assay were used to observe the inhibitory effect of lenvatinib on the growth of hepatocellular carcinoma cells. Flow cytometry was used to detect the apoptosis of regorafenib-resistant hepatocellular carcinoma cells treated with lenvatinib. The expression levels of related proteins were detected by western blot and immunohistochemical staining. The inhibitory effect of lenvatinib on the tumor formation ability of regorafenib-resistant hepatocellular carcinoma cells in vivo was observed by subcutaneous tumor formation experiment in mice. Results: CCK-8 and clone formation assay showed that lenvatinib could inhibit the proliferation of regorafenib-resistant hepatocellular carcinoma cells. The number of clones of HepG2, SMMC7721 and regorafenib-resistant HepG2, SMMC7721 cells in lenvatinib group (120.67±11.06, 53.00±11.14, 55.00±9.54, 78.67±14.64) were all lower than those in control group (478.00±24.52, 566.00±27.87, 333.67±7.02, 210.00±12.77, all P<0.05). Flow cytometry showed that lenvatinib could promote apoptosis of regorafenib-resistant hepatocellular carcinoma cells, the apoptosis rates of HepG2, SMMC7721 and regorafenib-resistant HepG2, SMMC7721 cells in lenvatinib group [(12.30±0.70)%, (9.83±0.38)%, (15.90±1.32)%, (10.60±0.00)%] were all higher than those in control group [(7.50±0.87)%, (5.00±1.21)%, (8.10±1.61)%, (7.05±0.78)%, all P<0.05]. The apoptosis-related protein levels suggested that apoptosis was increased in the treatment of lenvatinib. The animal study showed that lenvatinib can inhibit the growth of regorafenib-resistant cells in vivo. Immunohistochemistry and western blot results showed that lenvatinib could down-regulate the abnormally activated IGF1R/Mek/Erk signaling pathway in regorafenib-resistant cells. Conclusion: Lenvatinib can reverse regorafenib resistance in hepatocellular carcinoma, possibly by down-regulating IGF1R/Mek/Erk signaling pathway.

Abstract
OBJECTIVE To construct a modABC gene knockout strain of Proteus mirabilis and explore the effect of modABC gene deletion on biological characteristics of Proteus mirabilis. METHODS Fusion PCR was used to obtain the fusion gene of modABC and the kanamycin-resistant gene Kn, which was ligated with the suicide vector pCVD442 and transduced into Proteus mirabilis. The modABC gene knockout strain of Proteus mirabilis was obtained after homologous recombination with the suicide vector. PCR and Sanger sequencing were used to identify genomic deletion of modABC gene in the genetically modified strain. The concentration of molybdate in the wild-type and gene knockout strains was determined using inductively coupled plasma mass spectrometry (ICP-MS), and their survival ability in LB medium was compared under both aerobic and anaerobic conditions. RESULTS PCR and sanger sequencing confirmed genomic deletion of modABC gene in the obtained Proteus mirabilis strain. The concentration of intracellular molybdenum in the modABC gene knockout strain was 1.22 mg/kg, significantly lower than that in the wild-type strain (1.46 mg/kg, P < 0.001). Under the aerobic condition, the modABC gene knockout strain grown in LB medium showed no significant changes in survival ability compared with the wild-type strain, but its proliferation rate decreased significantly under the anaerobic condition and also when cultured in nitrate-containing LB medium under anaerobic condition. CONCLUSION Homologous recombination with the suicide vector can be used for modABC gene knockout in Proteus mirabilis. modABC gene participates in molybdate uptake and is associated with anaerobic growth of Proteus mirabilis in the presence of nitrate.

Abstract
Oxidative stress modulates carcinogenesis in the liver; however, direct evidence for metabolic control of oxidative stress during pathogenesis, particularly, of progression from cirrhosis to hepatocellular carcinoma (HCC), has been lacking. Deficiency of transaldolase (TAL), a rate-limiting enzyme of the non-oxidative branch of the pentose phosphate pathway (PPP), restricts growth and predisposes to cirrhosis and HCC in mice and humans. Here, we show that mitochondrial oxidative stress and progression from cirrhosis to HCC and acetaminophen-induced liver necrosis are critically dependent on NADPH depletion and polyol buildup by aldose reductase (AR), while this enzyme protects from carbon trapping in the PPP and growth restriction in TAL deficiency. Both TAL and AR are confined to the cytosol; however, their inactivation distorts mitochondrial redox homeostasis in opposite directions. The results suggest that AR acts as a rheostat of carbon recycling and NADPH output of the PPP with broad implications for disease progression from cirrhosis to HCC.

Abstract
Despite their crucial role in health and disease, our knowledge of immune cells within human tissues remains limited. We surveyed the immune compartment of 16 tissues from 12 adult donors by single-cell RNA sequencing and VDJ sequencing generating a dataset of ~360,000 cells. To systematically resolve immune cell heterogeneity across tissues, we developed CellTypist, a machine learning tool for rapid and precise cell type annotation. Using this approach, combined with detailed curation, we determined the tissue distribution of finely phenotyped immune cell types, revealing hitherto unappreciated tissue-specific features and clonal architecture of T and B cells. Our multitissue approach lays the foundation for identifying highly resolved immune cell types by leveraging a common reference dataset, tissue-integrated expression analysis, and antigen receptor sequencing.

Abstract
Currently, Coronavirus Disease 2019 (COVID-19)-a respiratory contagion spreading through expiratory droplets-has evolved into a global pandemic, severely impacting the public health. Importantly, the emerging of immune evasion SARS-CoV-2 variants and the limited effect of current antivirals against SARS-CoV-2 in clinical trials suggested that alternative strategies in addition to the conventional vaccines and antivirals are required to successfully control the COVID-19 pandemic. Here, we propose to use liquid-repellent coatings to prevent the spread of the disease in the absence of effective vaccines, antimicrobial agents, or therapeutics, wherein the deposition and penetration of pathogen droplets are prohibited. We use SARS-CoV-2 as a model pathogen and find that SARS-CoV-2 remnants are reduced by seven orders of magnitude on coated surfaces, yielding a repelling efficacy far outperforming the inactivation rate of disinfectants. The SARS-CoV-2 remnant scales exponentially with the liquid/solid adhesion, uncovering the mechanism and effective means for minimizing pathogen attachment. The antipathogen coating that both repels and inactivates pathogens is demonstrated by incorporating the super-liquid-repellent coating with antipathogen additives. Together with its versatility over a wide range of substrates and pathogens, the novel antipathogen coating is of considerable value for infection control in everyday life as well as during pandemics.

Abstract
OBJECTIVE To prepare metallic organic nanoparticles that produce synergistic effect in high-intensity focused ultrasound (HIFU) therapy of tumors. OBJECTIVE Glucose oxidase (GOD), MnO2, ferric iron (Fe3+) and doxorubicin (DOX) were self-assembled by physical adsorption with previously prepared manganese dioxide (MnO2) nanoparticles to obtain GOD-MnO2-Fe3+-DOX nanoparticles (GMFD NPs). HepG2 tumor-bearing nude mouse models were given intravenous injections of normal saline or GMFD NPs followed 4 h later by HIFU at the acoustic power of 90 W with a total treatment time of 3 s. The changes of tumor gray value before and after HIFU irradiation were observed and 24 h after HIFU irradiation, coagulation necrosis in the tumor tissues was examined; the histological changes of the tumor tissues were observed with HE staining. OBJECTIVE We successfully prepared GMFD NPs, which had an average particle size of 131.23±0.84 nm with a surface potential of 21.87±1.72 mV. GMFD NPs, with a drug loading rate of 40.18%, was capable of releasing more than 77.2% of the loaded DOX within 4 h in acidic environment. In the tumor-bearing mouse models, HIFU irradiation following GMFD NP injection, as compared with saline injection, resulted in significantly enhanced gray value of the tumor (25.5±4.5 vs 18.7±3.9, P=0.04) and greater volume of coagulation necrosis (105.80 ± 1.21 mm3 vs 38.02 ± 0.34 mm3). The energy efficiency factor (EEF) was significantly lower in GMFD NPs group than in saline group (1.79 vs 4.97, P < 0.001). OBJECTIVE GMFD NPs prepared in this study can enhance tumor ablation efficacy of HIFU and release DOX for further treatment of the residual tumor tissue in mice.

Abstract
Objective: To investigate the species and concentrations of airborne pollens in Wuhan urban area and their correlation with the number of visits of allergic rhinitis patients. Methods: Retrospective analysis of pollen dispersal characteristics and the number of patients with allergic rhinitis presenting to Tongji Hospital of Huazhong University of Science and Technology in Wuhan city from October 2017 to September 2018, as well as pollen allergen testing results of patients with allergic rhinitis presenting to the Department of Allergy during the same period. Pollen data was collected by a 1-year air sampling conducted in Wuhan City during the same period using the volumetric method. The samples were examined microscopically to identify airborne pollen species and counted, and the concentrations of various pollens were calculated. Information on patients with allergic rhinitis who came to the hospital during the same period was collected, and the correlation between pollen concentration and the number of patient visits was statistically analyzed using Pearson correlation analysis. Results: A total of 35 types of airborne pollen were collected from October 2017 to September 2018. The dominant pollens in spring were Moraceae (68.46%, 1 042/1 522), Pendula (12.22%, 186/1 522) and Cupressaceae (2.30%, 35/1 522); in summer and autumn, the dominant pollens were Artemisia (3.81%, 58/1 522), Humulus (4.01%, 61/1 522) and Ambrosia (0.59%, 9/1 522). The peak number of visits for allergic rhinitis patients occurred in March-April and July-September, both exceeding 2 200 visits and reaching a maximum of 2 545 visits. There was a very weak correlation between the number of visits and the total pollen concentration (r=0.17, P=0.001). The average monthly pollen skin prick test positive rate of patients with allergic rhinitis was highest in March-May, exceeding 40% with a maximum of 45.73%, and there was a significant correlation between the positive pollen skin prick test positive rate and the average monthly pollen concentration (r=0.62, P=0.031). Conclusions: Pollen species and concentrations fluctuated continuously with time in Wuhan urban area, with peak pollen dispersal in spring from March to April and in autumn from August to September. The number of visits to patients with allergic rhinitis and the positive pollen skin prick test positive rate increased accordingly during the peak pollen concentration periods.

Abstract
The effects of cigarette smoking on the risk of herpes zoster (HZ) infection remain unclear. This study aimed to examine the association between cigarette smoking and HZ. Participants were collected from four rounds (2001, 2005, 2009 and 2013) of the Taiwan National Health Interview Survey. Incident cases of HZ were identified from the Taiwanese National Health Insurance database. Of the 57 641 participants, 3346 developed HZ during the observation period. After controlling for confounders, current smokers had a lower risk of incident HZ than never-smokers (adjusted hazard ratio 0.69; 95% CI 0.62-0.77). There was a trend toward a decreased risk of HZ with increasing numbers of cigarettes per day, years of smoking and cumulative pack-years of smoking among current smokers (Ptrend < 0.001). Former smoking was not associated with risk of HZ. In conclusion, current smoking was significantly associated with a decreased risk of developing HZ.

Abstract
The increasing resistance of Neisseria gonorrhoeae to any current antibiotic treatment and the difficulties associated with the use of prevention means such as condom urge the need for alternative methods to prevent this sexually transmitted infection. In this work, a prevention strategy based on the use of a vaginal gel containing Lactobacilli was assessed in vitro. A Lactobacillus crispatus strain (ATCC 33197) was selected based on the published data on its ability to inhibit Neisseria gonorrhoeae. Its probiotic properties were first characterized. Then, a thermo-sensitive hydrogel containing 21.5% of poloxamer 407, 1% of sodium alginate and 9log10 CFU of Lactobacillus crispatus per gel sample (5 g) was developed. The gelation temperature and the rheological characteristics of this formulation appeared suitable for a vaginal administration. Lactobacillus crispatus was viable in the gel for six months although a large amount of the bacteria was not culturable. The ability of Lactobacillus crispatus to inhibit Neisseria gonorrhoeae was still observed with the gel. Such system, thus, appeared promising for the prevention of gonorrhea.

Abstract
The aim of this paper is to investigate the time and thermal stability of innovative multicompartmental nanoparticles. These particles, having a hydrophilic side and a hydrophobic side, belong to the family of Janus particles and are promising tools to carry active ingredients with opposite solubilities in a unique nanocarrier. The stability of nanoparticles obtained with mainly two types of polyoxylglycerides (Labrafil® M2125 CS and Labrafil® M1944 CS) has been investigated. The suspensions describe a two-step maturation/destabilization process with an Ostwald ripening phase followed by the coalescence of the particles. The effect of lipid composition and temperature on these steps has been investigated in deep as stability with temperature is a critical parameter to consider in order to envisage the development of any formulation for pharmaceutical or cosmetic uses. These nanoparticles were particularly stable at room temperature as their hydrodynamic diameter did not change significantly for 20 months. Contrarily, a strong dependency to temperature appears when storage temperature increases from 25 °C to 43 °C. Indeed, Labrafil® M1944 CS seemed to undergo a progressive destabilization where a significant increase of particles size is visible from 25 °C and phase separation occurred after 4 months at 32 °C. At the opposite, Labrafil® M2125 CS remained stable until 36 °C and reached a threshold temperature between 32 °C and 36 °C after which Labrafil® M2125 CS underwent a consequent increase of particles size at the longer time, i.e. after 6 months. Moreover, Labrafil® M2125 CS formulation was stable at least 3 months at 43 °C.

Abstract
We present two prescriptions for broadband ($ {\sim} 77 - 252\;{\rm GHz} $), millimeter-wave antireflection coatings for cryogenic, sintered polycrystalline aluminum oxide optics: one for large-format (700 mm diameter) planar and plano-convex elements, the other for densely packed arrays of quasi-optical elements-in our case, 5 mm diameter half-spheres (called "lenslets"). The coatings comprise three layers of commercially available, polytetrafluoroethylene-based, dielectric sheet material. The lenslet coating is molded to fit the 150 mm diameter arrays directly, while the large-diameter lenses are coated using a tiled approach. We review the fabrication processes for both prescriptions, then discuss laboratory measurements of their transmittance and reflectance. In addition, we present the inferred refractive indices and loss tangents for the coating materials and the aluminum oxide substrate. We find that at 150 GHz and 300 K the large-format coating sample achieves $ (97 \pm 2)\% $ transmittance, and the lenslet coating sample achieves $ (94 \pm 3)\% $ transmittance.

Abstract
Objective: To analyze the epidemiological characteristics of adult inpatients with gas burns in the Department of Burns of Hwa Mei Hospital of University of Chinese Academy of Sciences (hereinafter referred to as the author's unit) , so as to provide evidence for the prevention of gas burn. Methods: Medical records of all inpatients with flame burns admitted to the author's unit from January 2011 to December 2017 were collected. The percentage of adult inpatients with gas burns in total inpatients with flame burns in the same period, and their gender, age, injury season, accident place, burn severity, common compound injury, complication, population caliber, education, industry, as well as the pre-injury disease and prognosis of elderly inpatients with gas burns were retrospectively analyzed. In addition, the age, accident place, education, and industry of the floating population in the adult inpatients with gas burns were analyzed separately and compared with the total population of adult inpatients with gas burns in 7 years. Data were processed with chi-square test or Fisher's exact probability test (Monte Carlo algorithm). Results: During the 7 years, 1 490 inpatients with flame burns were admitted to the author's unit, among which 511 were adult inpatients with gas burns, accounting for 34.30%. The number of adult inpatients with gas burns increased gradually during the 7 years, but its percentage in the total inpatients with flame burns during the same period showed no significant difference (χ(2)=7.087, P>0.05). Among the 511 adult inpatients with gas burns (hereinafter referred to as the patients in this group), there were 315 males and 196 females, with a male/female ratio of 1.61 to 1.00, and the middle-aged patients were the most, up to 270 cases, accounting for 52.84%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in gender and age (χ(2)=54.810, 27.832, P<0.01). Among the patients in this group, most were injured in summer, totally 251 cases, accounting for 49.12%, and the accident place was mainly at home, totally 388 cases, accounting for 75.93%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in injury season (χ(2)=42.254, P<0.01), but not in accident place (χ(2)=6.782, P>0.05). The patients in this group were mainly with moderate burns (237 cases, accounting for 46.38%), and the distribution trend of burn severity of adult inpatients with gas burns was basically the same during the 7 years (χ(2)=19.680, P>0.05); 176 patients (34.44%) were accompanied by inhalation injury, and 30 patients (5.87%) were accompanied by blast injury of lung; post injury complications occurred in 20 patients (3.91%). In the elderly inpatients with gas burns, 44.44% (32/72) were accompanied by pre-injury basic diseases, and the proportion of death or unhealed reached 18.06% (13/72). Most of the patients in this group were permanent residents (358 cases, accounting for 70.06%) and received secondary education (304 cases, accounting for 59.49%), and the majority of them were engaged in manufacturing/construction (138 cases, accounting for 27.01%), self-employed business (90 cases, accounting for 17.61%), and catering (90 cases, accounting for 17.61%) industries. The distribution of adult inpatients with gas burns during the 7 years was significantly different in population caliber, education, and occupation (χ(2)=17.496, 29.898, 88.896, P<0.05 or P<0.01). Among the patients of this group, the floating population were mainly young (90 cases, accounting for 58.82%) and middle-aged (62 cases, accounting for 40.52%), with main accident place at home (97 cases, accounting for 63.40%), generally received secondary education (101 cases, accounting for 66.01%), and were mainly engaged in manufacturing/construction (71 cases, accounting for 46.41%), self-employed business (26 cases, accounting for 16.99%), and catering (20 cases, accounting for 13.07%) industries. Compared with the total adult inpatients with gas burns in 7 years, the floating population were younger, more injured in the workplace, and more concentrated in industry (χ(2)=42.924, 9.390, 27.819, P<0.01). Conclusions: Gas burn was the leading injury cause of inpatients with flame burns in the author's unit, which mainly occurred in summer and at home; the patients were mainly male, young and middle-aged, and permanent residents, most of which were with moderate burn, often accompanied by inhalation injury. Most of the patients were of secondary education, engaged in manufacturing/construction, self-employed business, and catering industries, among which the floating population were younger, more injured in the workplace, and more concentrated in industry. In order to prevent gas burn, we should pay more attention to the propaganda and education of gas safety among young and middle-aged men, floating population, retired old people and housewives, especially in summer, we should do a good job in gas safety inspection at home. In addition, we should urge enterprises to further strengthen the supervision of production safety.

Abstract
OBJECTIVE How implementing diagnostic-related grouping (DRG) payment affected the use of opioids and psychotropics by hip fracture patients following hospitalization remained unknown. DESIGN A retrospective, pre-post design, cohort study of data excerpted from Taiwan's National Health Insurance Research database (NHIRD). SETTING AND PARTICIPANTS Adults aged ≥ 65 years first admitted for hip fracture surgery from 2007 to 2012 were identified and divided into two 1:1 propensity-score matched groups: pre-DRG (2007-2009); DRG (2010-2012). MEASUREMENTS The outcome measures were use of opioid and/or psychotropic drugs within 30 days, 90 days, 180 days, and 365 days after discharge. RESULTS Data of 16,522 subjects were excerpted, and 8,261 propensity-score matched subjects each classified into the pre-DRG and DRG groups. After adjustment, the DRG group was significantly more likely than the pre-DRG group to have used antipsychotics after discharge from hip fracture surgery (≤30 days, ≤90 days, ≤180 days and ≤365 days). The DRG group also had significantly higher prescription rates of benzodiazepines and antipsychotics during the observation period. Moreover, the DRG group was less likely to use non-steroidal anti-inflammatory drugs (≤30 days, ≤90 days, ≤180 days and ≤365 days) and more likely to use acetaminophen (≤30 days, ≤180 days, and ≤365 days). CONCLUSIONS In conclusion, DRG implementation in Taiwan substantially increased post-acute prescription of antipsychotic and psychotropic agents for hip fracture patients, and changed use of analgesics, which may result in suboptimal quality and safety for these patients. Further research is needed to evaluate the long-term outcomes of DRG implementation, and the potential benefits of appropriate post-acute care bundled with DRG payment.

Abstract
BACKGROUND The Human Cell Atlas is a large international collaborative effort to map all cell types of the human body. Single-cell RNA sequencing can generate high-quality data for the delivery of such an atlas. However, delays between fresh sample collection and processing may lead to poor data and difficulties in experimental design. RESULTS This study assesses the effect of cold storage on fresh healthy spleen, esophagus, and lung from ≥ 5 donors over 72 h. We collect 240,000 high-quality single-cell transcriptomes with detailed cell type annotations and whole genome sequences of donors, enabling future eQTL studies. Our data provide a valuable resource for the study of these 3 organs and will allow cross-organ comparison of cell types. We see little effect of cold ischemic time on cell yield, total number of reads per cell, and other quality control metrics in any of the tissues within the first 24 h. However, we observe a decrease in the proportions of lung T cells at 72 h, higher percentage of mitochondrial reads, and increased contamination by background ambient RNA reads in the 72-h samples in the spleen, which is cell type specific. CONCLUSIONS In conclusion, we present robust protocols for tissue preservation for up to 24 h prior to scRNA-seq analysis. This greatly facilitates the logistics of sample collection for Human Cell Atlas or clinical studies since it increases the time frames for sample processing.

Abstract
We report the first detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB). The lensing signal is obtained using a new estimator that extracts the lensing dipole signature from stacked images formed by rotating the cluster-centered Stokes QU map cutouts along the direction of the locally measured background CMB polarization gradient. Using data from the SPTpol 500 deg^{2} survey at the locations of roughly 18 000 clusters with richness λ≥10 from the Dark Energy Survey (DES) Year-3 full galaxy cluster catalog, we detect lensing at 4.8σ. The mean stacked mass of the selected sample is found to be (1.43±0.40)×10^{14}M_{⊙} which is in good agreement with optical weak lensing based estimates using DES data and CMB-lensing based estimates using SPTpol temperature data. This measurement is a key first step for cluster cosmology with future low-noise CMB surveys, like CMB-S4, for which CMB polarization will be the primary channel for cluster lensing measurements.

Abstract
From June to November 2016, 5 patients with severe burns were admitted to our unit. Broad-spectrum antibiotic and fluconazole were used on patients as earlier empirical anti-infection therapy of bacteria and fungi. Seven to twenty-one days after injury, 5 patients developed fungal infection. Antifungal agents of caspofungin, voriconazole, and amphotericin B liposomewere were used according to the results of fungal culture, and the infected wounds were also treated with repeated debridement and dressing change. Multiple autologous skin grafts were performed after infection control of wounds. With the above antifungal infection treatment for 5 to 11 days, 2 patients' condition tended to be stable, and no fungus was found in wound secretion after cultured for many times. The patients were discharged with wounds healed after 52 to 54 days' hospital stay. Due to severe burns degree and or elder age, fungal infection aggravated and expanded to the trunk in the other 3 patients, then developed into burn sepsis, resulting in patients died of multiple organ failure secondary to sepsis.

Abstract
Objective: To explore whether early oral feeding after total laryngectomy is safe and effective by evaluating the incidence of pharyngocutaneous fistula (PCF) and the hospital duration. Methods: A retrospective cohort study was conducted, including 52 patients underwent total laryngectomy, plus partial tongue base resection (n=2), partial pharyngectomy (n=1), or pedicle flap (n=2) between January 2012 and October 2017. Patients who had a history of preoperative radiotherapy, chemotherapy or chemoradiotherapy, previous surgery for larynx or pharynx and who had severe complications were excluded. Early oral feeding started between 48 h and 72 h postoperatively, while delayed oral feeding started within postoperative day 8-10. The incidences of PCF in two groups were compared to evaluate whether PCF and early oral feeding was related. Multi-variables analysis was conducted to evaluate risk factors for PCF. Results: PCF rate was 19.2% among all patients, 11.1% in patients with early oral feeding and 23.5% in patients with delayed oral feeding. No significant statistically difference in PCF rate was found between two groups (χ(2)=0.506, P=0.477). Multi-variables analysis showed that oral feeding time (early or delayed) was not a independent risk factor of PCF (Two classification response variable Logistic regression, P=0.200, OR=0.242, 95%CI[0.028-2.118]). But low preoperative albumin level was observed as an independent risk factor for PCF (P=0.039, OR=0.848, 95% CI [0.726-0.992]). A negative correlation was observed between preoperative albumin level and PCF. And also there was not a significant difference in hospital duration between patients with early oral feeding and delayed oral feeding(U=268, P=0.464). Conclusion: For patients total laryngectomy with no previous history of radiotherapy, chemotherapy, chemoradiotherapy, early oral feeding after surgery is safe and effective.

Abstract
Abstract
Background
Patients diagnosed with ductal carcinoma in situ (DCIS) by core needle biopsy (CNB) have a great chance of upgrading invasive cancer on the final pathology. Positive axillary lymph nodes can be found in these patients. The present study sought to identify clinicopathological factors associated with upgrading and axillary lymph nodes metastasis in patients preoperatively diagnosed with DCIS by CNB.
Materials and Methods
This study identified 604 patients (cT1-3N0M0) with preoperative diagnosis of pure DCIS by CNB who had undergone axillary evaluation from August 2006 to December 2015 at Fudan University Shanghai Cancer Center (FUSCC). Predictors of upgrading and axillary lymph nodes metastasis were analyzed, respectively.
Results
Of all 604 patients, 513 (84.93%) and 91 (15.07%) patients had undergone sentinel lymph nodes biopsy (SLNB) and axillary lymph nodes dissection (ALND), respectively. Overall, 121 (20.03%) and 193 (31.95%) patients were upgraded to DCIS with microinvasion (DCISM) and IDC on final pathology, respectively. Positive axillary lymph nodes were identified in 41 (6.79%) patients, of which 35 (5.80%) patients had 1-2 positive axillary lymph nodes, 6 (0.99%) patients had 3 or more positive axillary lymph nodes. Among patients with axillary lymph nodes metastasis, 4 (9.76%), 4 (9.76%) and 33 (80.48%) patients were in DCIS, DCISM and IDC group, respectively. Predictors of upgrading included tumor size on ultrasonography (P=0.001), Ki-67 (P=0.046) and molecular subtype (P=0.007) in univariate analysis. In multivariate analysis, patients with larger tumor size on ultrasonography (>2cm) (OR 1.767, P=0.001) were more likely to be upgraded on final pathology. Also, ER+ HER2+ patients were more likely to be upgraded than ER+ HER2- patients (OR 1.659, P=0.047). Factors associated with axillary lymph nodes metastasis included nipple discharge (P<0.001), tumor size on pathology (P=0.037), number of lesions (P=0.039), axillary evaluation methods (P=0.029) and molecular subtype (P=0.049) in univariate analysis. Whereas, only nipple discharge and larger tumor size on pathology (>2cm) reached statistical significance in multivariate analysis (OR 5.959, P<0.001; OR 2.361, P=0.042). In addition, further analysis showed upgrading on final pathology had a significant influence on axillary lymph nodes status (P<0.001). However, this correlation was not shown between patients with DCIS and DCISM in pairwise comparison.
Conclusion
The data of upgrading and axillary lymph nodes metastasis in patients with an initial diagnosis of DCIS by CNB was comparable in this cohort with published data. Despite of a 51.98% upgrading rate, the rate of axillary lymph nodes metastasis in these patients is low, which supports the omission of axillary evaluation in selected patients.

Abstract
Clarification of TP53 alterations is important to understand the mechanisms underlying the development of diffuse astrocytomas. It has been suggested that the alleles of TP53 at codon 72 differ in their ability to induce apoptosis in human cancers. The aim of this study was to analyze the possible association of TP53 mutation, p53 overexpression, and p53 codon 72 polymorphism with susceptibility to apoptosis in adult Brazilian patients with diffuse astrocytomas. We analyzed 56 surgical specimens of diffuse astrocytomas for alterations of TP53, using polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) direct sequencing. p53 and cleaved caspase 3 protein expression were assessed by immunohistochemistry. We found TP53 mutations in 19.6% (11 out of 56) of tumors tested, with the lowest mutation rate found in the cases of glioblastomas (8.8%) (p = 0.03). Only 16.1% of tumors tested showed cleaved caspase 3-positive staining, demonstrating that apoptosis is very inhibited in these tumors. All tumors having TP53 mutation and p53 accumulation had no expression of cleaved caspase 3. Additionally, no association was observed in tumors having proline and arginine alleles and expression of cleaved caspase 3. We concluded that clarification of the TP53 alterations allows a better understanding of the mechanisms involved in the progression of diffuse astrocytomas, and the allele status at codon 72 was not associated with apoptosis in these tumors.

Abstract
Rabbit haemorrhagic disease virus (RHDV, or GI.1) is a calicivirus in the genus Lagovirus that has been widely utilized in Australia as a biological control agent for the management of overabundant wild European rabbit (Oryctolagus cuniculus) populations since 1996. Recently, two exotic incursions of pathogenic lagoviruses have been reported in Australia; GI.1a-Aus, previously called RHDVa-Aus, is a GI.1a virus detected in January 2014, and the novel lagovirus GI.2 (previously known as RHDV2). Furthermore, an additional GI.1a strain, GI.1a-K5 (also known as 08Q712), was released nationwide in March 2017 as a supplementary tool for wild rabbit management. To discriminate between these lagoviruses, a highly sensitive strain-specific multiplex RT-PCR assay was developed, which allows fast, cost-effective and sensitive detection of the four pathogenic lagoviruses currently known to be circulating in Australia. In addition, we developed a universal RT-qPCR assay to be used in conjunction with the multiplex assay that broadly detects all four viruses and facilitates quantification of viral RNA load in samples. These assays enable rapid detection, identification and quantification of pathogenic lagoviruses in the Australian context. Using these assays, a novel recombinant lagovirus was detected in rabbit tissue samples, which contained the non-structural genes of GI.1a-Aus and the structural genes of GI.2. This variant was also recovered from the liver of a European brown hare (Lepus europaeus). The impact of this novel recombinant on Australian wild lagomorph populations and its competitiveness in relation to circulating field strains, particularly GI.2, requires further studies.

Abstract
Graphitization occurs during the long-term service of a diamond-like carbon (DLC) modified artificial joint. Then, DLC wear debris, which are carbon particles with different sp2/sp3 ratios and sizes ranging from the nano- to micro-meter scale produced. In this paper, to promote the application of DLC coating for artificial joint modification, the cytotoxicity of DLC debris (nano-carbon particles, NCs) with different sp2/sp3 ratios was studied. The microstructure and physical characteristics of NCs with different sp2/sp3 ratios were investigated by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Transmission Electron Microscope (TEM) and Dynamic Light Scattering (DLS). Meanwhile, osteoblasts and macrophages were applied to characterize the cytotoxicity of the NCs. In vitro cytotoxicity assay results indicated that cells incubated with NCs of different sp2/sp3 ratios had greater osteogenic capacity, and these particles caused a weaker immune response in comparison with CoCrMo particles. Taken together, the results indicated that NCs with different sp2/sp3 ratios presented a good cytocompatibility than CoCrMo particles. But no significant differences were observed among NCs with different sp2/sp3 ratios. The better cytocompatibility of NCs is mainly attributable to their surface charge.

Abstract
Patients with DLC (diamond like carbon)-coated artificial joints may be exposed to a wide size range of DLC wear debris (DW). In this study, the cytotoxicity of DW of different size ranges (0-0.22, 0.22-0.65, 0.65-1.0, and 1.0-5.0 μm) was evaluated. The microstructure and physical characteristics of DW were investigated by Raman spectroscopy, transmission electron microscopy (TEM), scanning electron microscope (SEM), and dynamic light scattering (DLS). Macrophages, osteoblasts, and fibroblasts were incubated with DW of different size ranges respectively followed by cytotoxicity evaluations of inflammatory cytokines, alkaline phosphatase (ALP) assays, and related signal protein expression analysis. The results showed that, except for the size range of 0-0.22 μm, DW cytotoxicity showed a size-dependent (0.22-5.0 μm) decrease with increasing size. Within the range of 0.22-5.0 μm, DW of larger size resulted in lessened inflammatory response and enhanced osteoblastogenesis and fibrogenesis, with increased viability of cells (macrophages, osteoblasts, and fibroblasts), better morphology, less release of pro-inflammatory factors and more release of anti-inflammatory factors. The results demonstrated that DW sizes below 0.22 μm had less negative effects on cell adhesion and growth because of the BSA (bovine serum albumin) encapsulation effect. These findings provide valuable knowledge about the comprehensive mechanism of promotion of inflammatory response and inhibition of osteoblastogenesis and fibrogenesis induced by DW. In conclusion, an effective system of biocompatibility evaluation for different sizes of DW was derived.
