Abstract
OBJECTIVE Currently, there are still no convincing clinical models predicting closed lower extremity fracture-associated deep vein thrombosis in patients treated through thromboprophylactic methods. We aimed at using two retrospective cohorts to develop and externally verify a clinical prediction model for deep vein thrombosis in patients treated with anticoagulants after suffering closed lower extremity fractures. PATIENTS AND METHODS We evaluated the patients' pre- and post-operatively, to accurately determine the predictive power of the biomarkers and clinical risk factors. Two retrospective cohorts were used for the development and external verification of a pre-operative clinical prediction model (development: n = 2,253; verification: n = 833) and post-operative clinical prediction model (development: n = 1,422; verification: n = 449), respectively. RESULTS The C-indices were used to show the predicted incidence of objective thrombosis at the pre- and post-operative stage, which were then compared with the observed incidence of thrombosis in both cohorts. Biomarkers and clinical indicators were included in pre- and post-operative nomograms, which were adequately calibrated in both cohorts. The cross-validated C-indices of the pre- and post-operative clinical prediction models in the verification cohort were 0.706 (95% Cl, 0.67-0.74) and 0.875 (95% Cl, 0.84-0.91), respectively. CONCLUSIONS We present our findings of novel pre- and post-operative nomograms for the prediction of deep venous thrombosis in patients who received thromboprophylaxis after suffering closed lower extremity fractures.

Abstract
Objective: To explore the association between weight gain during the first half of pregnancy and the risk of hypertension disorder of pregnancy (HDP). Methods: This prospective cohort study recruited singleton pregnant women in the first trimester from November 2016 to March 2019 at 19 community hospitals in Tianjin. According to pre-pregnancy body mass index (BMI), the cohort was divided into 3 groups: underweight(BMI<18.5 kg/m2), normal-weight(18.5-24.9 kg/m2), and overweight/obese(≥25.0 kg/m2). The basic information of the participants was gathered through questionnaires, and the height, weight, and blood pressure of the participants were measured along with routine pregnancy examinations. The rate of gestational weight gain (rGWG) in the 3 periods (0-13+6, 14+0-20+6, and 0-20+6 weeks) of the participants was calculated. To observe the occurrence of HDP, the participants were followed up to 42 days postpartum. Using a generalized linear model, the association between rGWG at the 3 periods during the first half of pregnancy and HDP after 20 weeks of gestation was evaluated. Results: A total of 9 805 pregnant women were finally included, with the age of (30.6±3.8) years old, 9 418 (96.1%) Han ethnicity, and 6 845 (69.8%) primipara. There were 1 184 (12.1%), 6 831 (69.7%) and 1 790 (18.3%) participants in the underweight, normal-weight, and overweight/obese groups. Five hundreds and eight pregnant women were diagnosed with HDP (5.2%). The incidences of HDP were 1.8% (21/1 184), 3.9% (269/6 831), and 12.2% (218/1 790), respectively, in underweight, normal-weight, and overweight/obese groups. Adjusted for age, pre-pregnancy BMI, primipara, and family history of hypertension, women in the entire cohort with rGWG ≥ 0.18 kg/week before 13+6 weeks of pregnancy had a 28% higher HDP risk than those with rGWG ≤ 0.00 kg/week (RR=1.28, 95%CI 1.04-1.55, P=0.015), and the risk of HDP was increased by 39% in the overweight/obese group (RR=1.39, 95%CI 1.04-1.85, P=0.026), while no correlation was found between rGWG and HDP in underweight and normal-weight pregnant women (P>0.05). Weight gain during 14+0-20+6 weeks of pregnancy in any group was not related to the risk of HDP (P>0.05).In the entire cohort, compared to rGWG ≤0.14 kg/week, rGWG≥0.28 kg/week prior to 20+6 weeks increased HDP risk by 36% (RR=1.36, 95%CI 1.11-1.67, P=0.003). Normal-weight pregnant women with rGWG≥0.29 kg/week faced a 46% higher risk of HDP than those with rGWG≤0.15 kg/week (RR=1.46, 95%CI 1.11-1.93, P=0.008).In the overweight/obese group, excessive weight gain before 20+6 weeks seemed to increased risk of HDP, but the difference was not statistically significant (RR=1.35,95%CI 0.99-1.85, P=0.059), while the connection was nonexistent in underweight women. Conclusions: Except for pre-pregnancy underweight women, excessive weight gain during the first half of pregnancy is associated with increased risk of HDP among pregnant women.

Abstract
Objective: To investigate the relationship between high density lipoprotein cholesterol (HDL-C) and cardiovascular disease (CVD) and all-cause mortality in the elderly population. Methods: A total of 14 355 elderly persons aged ≥65 years, who participated in the annual physical examination in Kailuan Group in 2006 were included in this prospective cohort study. According to HDL-C level, the participants were divided into 4 groups: low-level group (HDL-C<1.30 mmol/L), intermediate-level group (1.30 mmol/L ≤HDL-C≤1.54 mmol/L), medium-high-level group (1.55 mmol/L ≤HDL-C≤1.80 mmol/L), high-level group (HDL-C≥1.81 mmol/L). Baseline data such as age, sex and blood lipid levels were collected and compared. Inpatient medical records and death information were obtained through the social security system, and CVD and all-cause mortality were analyzed. After adjusting for confounding factors, the medium-high-level group was used as the reference group. Cox proportional risk regression model was used to evaluate the impact of HDL-C on CVD and all-cause mortality events. The linear or nonlinear relationship between HDL-C level and CVD and all-cause mortality events was evaluated by restricted cubic spline regression model. Death competitive risk analysis was conducted, and sensitivity analysis was performed after excluding subjects with CVD or all-cause mortality within 1 year of follow-up and female participants. Results: The average age of this cohort was (71.5±5.5) years and follow-up time was (10.9±3.3) years. Compared with medium-high-level group, Cox proportional risk regression analysis showed that the HR (95%CI) of CVD and all-cause mortality in low-level group were 1.21 (1.06-1.38) (P<0.05) and 1.02 (0.95-1.11) (P>0.05), respectively; the HR (95%CI) of CVD events in high-level group was 1.17 (1.03-1.33) (P<0.05), and there was a marginal significant association with all-cause mortality, the HR (95%CI) was 1.07 (1.00-1.16) (0.05<P<0.1). The restricted cubic spline regression analysis showed that HDL-C was nonlinearly correlated with CVD (nonlinear correlation P<0.1), and presented a U-shaped curve trend, while HDL-C was linearly correlated with all-cause mortality (nonlinear correlation P>0.1). Conclusions: In the elderly population, the risk of CVD is lowest when the HDL-C level is 1.55-1.80 mmol/L, either high or low HDL-C is a risk factor for CVD. High HDL-C tends to be related to increased risk of all-cause mortality and low HDL-C is not related to increased risk of all-cause mortality.

Abstract
Abstract
Aim
NHSE/I and the RCS England have advocated that the separation of elective and surgical care is fundamental in recovering surgical services. It is suggested that the separation is physical, and many Trusts are transforming pathways into elective and emergency hospitals. Croydon Hospital (CHS) have created an alternative, with ‘a Hospital within a Hospital’, separating these pathways within one estate, and considers whether this is a successful model for the future.
Method
The day surgery unit on the ground floor was converted into an emergency centre with an ambulatory surgical hub, a hot clinic, clinical space, 4 emergency theatres and an USS room. The main theatre suite was converted into the Croydon Elective Centre (CEC) with a 12-bedded coronary catheter suite, a lift onto the second floor, 10 theatres, a 12 bedded children's day unit, Moorfields’ eye unit, a new canteen, an admissions unit as well as a 28-bedded elective ward with a new 4-bedded level 1.5 critical care unit.
Results
At the end of wave 1, 3,068 patients awaited treatment, an increase of 30.44% of baseline activity with theatre activity at 28% of normal activity. Activity resumed to 100% within 6 weeks of CEC go live. 2/9,606 patients were Covid-19 positive in the first year. During wave 2, 60% of pre-Covid-19 activity continued. Currently, 2,098 patients await treatment.
Conclusion
The implementation of a surgical hub has supported the treatment of patients as well as provided continuous training opportunities for surgical and anaesthetic trainees as well as the theatre team.

Abstract
Objective: To observe the effect of liraglutide on the correlation between nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing protein 3 (NLRP3) infl ammasome and nonalcoholic fatty liver disease (NAFLD). Methods: Thirty-nine NAFLD cases (group N) and thirty-nine healthy subjects (group C) were selected from the physical examination center, and their general data were collected to determine the serum levels of NLRP3, IL-1β, and IL-18. The differences and correlations were analyzed between the two sets of indicators. Thirty male SD rats were randomly divided into normal (NC, n=10) and high-fat diet group (HF, n=20). The normal group were fed with normal diet and high-fat diet group were fed with high-fat diet. After 12 weeks of feeding, HF group was randomly divided into HF group (n=10) and liraglutide group (100L, n=10), and were given 0.5 ml/kg sterile isotonic saline and 100 g/kg liraglutide subcutaneously twice a day, respectively. Four weeks later, serum biochemical indicators, liver NLRP3 infl ammasome protein expression, and infl ammatory cytokine conditions were detected in each group. Statistical analysis was performed using t test, oneway analysis of variance (ANOVA) or χ2 test. Results: There were no statistically signifi cant differences between N and C group in terms of age, gender, diastolic blood pressure, glycosylated hemoglobin, mean platelet volume, erythrocyte distribution width, serum low-density lipoprotein cholesterol (HDL-Ch), total cholesterol, and total bileacid. Compared with group C, group N had elevated systolic blood pressure, body mass index (BMI), fasting blood glucose, blood creatinine, alkaline phosphatase (ALP), NLRP3, interleukin (IL)-1β, IL-18, TG, blood uric acid, γ-glutamyltransferase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and white blood cell counts, while HDL-Ch and total bilirubin were depleted than group C, and the difference was statistically significant (P< 0.05). NLRP3 was positively correlated with systolic blood pressure, BMI, fasting blood glucose, serum creatinine, IL-1β, IL-18, triglycerides, serum uric acid, GGT, ALT, AST, but negatively correlated with total bilirubin and HDL-Ch, and the difference was statistically signifi cant. Compared with NC group, HF group had significantly increased body mass, liver mass, serum biochemical indicators (triglycerides, AST, ALT), liver NLRP3 inflammasome protein expression, and inflammatory cytokines. After treatment with liraglutide, 100L group indicators were signifi cantly decreased when compared to HF group. Conclusion: Compared with healthy subjects, the infl ammation-related indicators, body mass, blood lipids and liver function-related indicators are signifi cantly changed in patients with NAFLD, which is also consistent with the results of rat model study. Liraglutide treatment had improved NAFLD to certain extent in NAFLD rats, so NLRP3 regulation may be one of the mechanisms to improve liver inflammation and steatosis.

Abstract
Objective: To address the limitations of existing methods and tools for evaluating clinical practice guidelines, we aimed to develop a comprehensive instrument focusing on the three main dimensions of guideline development: scientificity, transparency, applicability. We will use it to rank the guidelines according to the scores. We abbreviated it as STAR, and its reliability, validity and usability were also tested. Methods: A multidisciplinary expert working group was set up, including methodologists, statisticians, journal editors, medical professionals, and others. Scoping review, Delphi methods and hierarchical analysis were used to determine the final checklist of STAR. Results: The new instrument contained 11 domains and 39 items. Intrinsic reliability of each domain was indicated by Cronbach's α coefficient, with a average value of 0.646. The Cohen's kappa coefficients for methodological evaluators and clinical evaluators were 0.783 and 0.618. The overall content validity index was 0.905. The R2 for the criterion validity analysis was 0.76. The average score for usability of the items was 4.6, and the mean time spent to evaluate each guideline was 20 minutes. Conclusion: The instrument has good reliability, validity and evaluating efficiency, and can be used for evaluating and ranking guidelines more comprehensively.

Abstract
BackgroundStrong biologic rationale supports both vitamin D and marine omega-3 (n-3) fatty acids for prevention of autoimmune disease (AD). Within the randomized, double-blind, placebo-controlled VITamin D and OmegA-3 TriaL (VITAL), we tested the effects of these supplements on AD incidence. We previously reported results after 5.3 years of randomized follow-up showing overall protective effects for vitamin D on AD incidence (HR 0.78, 95% CI 0.61-0.99) and suggestive results for n-3 fatty acids (HR 0.85, 95%CI 0.67-1.08)1.ObjectivesWe aimed to test effects of these supplements with two more years of post-intervention follow-up in VITAL.MethodsVITAL enrolled and randomized men and women (age ≥50 and ≥55 years, respectively) in a 2-by-2 factorial design to vitamin D3 (2000 IU/d) and/or n-3 fatty acids (1000 mg/d) or placebo and followed for median 5.3 years. Here, we followed participants for another 2 years of observation to assess for sustained effects. Incident AD diagnoses were reported by participants annually and confirmed by medical record review by expert physicians using existing classification criteria. The primary endpoint was total incident AD, including rheumatoid arthritis (RA), polymyalgia rheumatica (PMR), autoimmune thyroid disease (AITD), psoriasis, and all others. Pre-specified secondary endpoints included individual common AD; and probable AD. Cox models calcuated hazard ratios (HR) for incident ADs.ResultsOf 25,871 participants randomized, 71% self-reported non-Hispanic Whites, 20% Black, 9% other racial/ethnic groups, 51% women, mean age was 67.1 years. During 7.5 years median follow-up, confirmed AD was diagnosed in 156 participants in vitamin D arm vs 198 in vitamin D placebo arm, HR 0.79 (0.64-0.97). Incident AD was confirmed in 167 participants in n-3 fatty acid arm and 187 in n-3 fatty acid placebo arm, HR 0.89 (0.72-1.10). For vitamin D, HRs trended toward reduction for RA 0.67 (0.37- 1.21), PMR 0.69 (0.46-1.03) and psoriasis 0.57 (0.33-0.99). For n-3 fatty acids, HRs trended toward reduction for RA 0.55 (0.30-1.10) and AITD 0.61 (0.33-1.12). Vitamin D’s effect on AD incidence was stronger in those with body mass index (BMI) < 25 (HR 0.65, 0.44-0.96) than ≥ 25 kg/m2 (p interaction 0.01).ConclusionSupplementation for 5.3 years with 2000 IU/day vitamin D (compared to placebo), followed by 2 years of observational follow-up, significantly reduced overall incident AD by 21% in older adults. HRs for RA, PMR and psoriasis trended toward reduction with vitamin D, with stronger effect in those with normal BMI. Supplementation with 1000 mg/day n-3 fatty acids did not significantly reduce total AD.References[1]Hahn J et al, BMJ, 2022 Jan 26;376: e066452.Table 1.Hazard Ratios for Primary and Secondary Endpoints, by Randomized Assignment to Vitamin D/Placebo (Left), N-3 Fatty Acids/Placebo (Right)aEndpointVitamin D3(N=12,927)Placebo (N=12,944)Hazard Ratio (95% CI)pN-3 Fatty Acids (N=12,933)Placebo (N=12,938)Hazard Ratio (95% CI)pPrimary: Confirmed AD1561980.79 (0.64-0.97)0.031671870.89 (0.72-1.10)0.27Secondary:Confirmed + probable AD2653210.83 (0.70-0.97)0.022713150.86 (0.73-1.01)0.06Excluding subjects with any pre-randomization AD Confirmed AD1271620. 79 (0.62-0.99)0.041411480.95 (0.75-1.20)0.66 Confirmed + probable AD2112700. 78 (0.65-0.94)0.0072322490.93 (0.78-1.11)0.41Excluding first 2 years follow-up Confirmed AD861300.66 (0.50-0.87)0.0031041120.92 (0.71-1.21)0.56 Confirmed + probable AD1472050.72 (0.58-0.89)0.0021721800.95 (0.77-1.17)0.63Individual ADb RA18270.67 (0.37-1.21)0.1816290.55 (0.30-1.01)0.06 PMR39570.69 (0.46-1.03)0.0746500.92 (0.61-1.37)0.67 AITD27181.50 (0.82-2.71)0.1917280.61 (0.33-1.12)0.11 Psoriasis20350.57 (0.33-0.99)0.0534211.62 (0.94-2.79)0.08aAnalyses from Cox regression models controlled for age, sex, race, and other (n-3 fatty acid or vitamin D) randomization group bConfirmed AD.Figure 1.Disclosure of InterestsKaren Costenbader Consultant of: Astra Zeneca, Glaxo Smith Kline, Neutrolis, Grant/research support from: Merck, Exagen, Gilead, Nancy Cook: None declared, I-min Lee: None declared, Jill Hahn: None declared, Joseph Walter: None declared, Vadim Bubes: None declared, Gregory Kotler: None declared, Nicole Yang: None declared, Sonia Friedman: None declared, Erik Alexander: None declared, JoAnn Manson: None declared.

Abstract
Over the past few decades, neuroimaging has become a ubiquitous tool in basic research and clinical studies of the human brain. However, no reference standards currently exist to quantify individual differences in neuroimaging metrics over time, in contrast to growth charts for anthropometric traits such as height and weight1. Here we assemble an interactive open resource to benchmark brain morphology derived from any current or future sample of MRI data ( http://www.brainchart.io/ ). With the goal of basing these reference charts on the largest and most inclusive dataset available, acknowledging limitations due to known biases of MRI studies relative to the diversity of the global population, we aggregated 123,984 MRI scans, across more than 100 primary studies, from 101,457 human participants between 115 days post-conception to 100 years of age. MRI metrics were quantified by centile scores, relative to non-linear trajectories2 of brain structural changes, and rates of change, over the lifespan. Brain charts identified previously unreported neurodevelopmental milestones3, showed high stability of individuals across longitudinal assessments, and demonstrated robustness to technical and methodological differences between primary studies. Centile scores showed increased heritability compared with non-centiled MRI phenotypes, and provided a standardized measure of atypical brain structure that revealed patterns of neuroanatomical variation across neurological and psychiatric disorders. In summary, brain charts are an essential step towards robust quantification of individual variation benchmarked to normative trajectories in multiple, commonly used neuroimaging phenotypes.

Abstract
Objective: To analyze the eligibility of empirical antibiotic therapy in culture positive sepsis in the pediatric intensive care unit (PICU), and to explore the application of antibiotic de-escalation (ADE) in children with sepsis and its impact on prognosis. Methods: A total of 123 children with sepsis-associated organ dysfunction or septic shock admitted to the PICU of Shengjing Hospital of China Medical University from January 2018 to December 2020 were retrospectively analyzed. The general information, laboratory tests, the use of empirical anti-bacterial drugs and the application of ADE were collected. According to the adjustment of anti-bacterial drugs, these children were divided into ADE group and non-ADE group. Comparisons between groups were performed with unpaired Student t test, or Mann-Whitney U test, or chi-square test or Fisher exact test. Results: In these 123 children, 70 were males and 53 were females, the age was 11.4 (2.8, 56.5) months. Body fluid culture was detected positive in 41 children including 3 children (7.3%) who received inadequate empirical antibiotic therapy and 38 children (92.7%) who received adequate empirical antibiotic therapy. Excluding 10 children who received appropriate therapy, 28 received unnecessary broad-spectrum antibiotics. There were no significant differences regarding the PICU all-cause mortality rates, length of PICU stay, hospitalization cost, duration of mechanical ventilation, as well as incidences of re-infection between the ADE group (n=46) and non-ADE group (n=77) (all P>0.05). However, among the 101 children who have used antibiotics against multidrug-resistant organism, the duration of such antibiotics use in ADE group (n=43) was shorter than that in non-ADE group (n=58) (5.0 (4.0, 12.0) vs. 9.5 (7.0, 13.0) d, Z=-3.14, P=0.002). Conclusions: Overuse of unnecessary broad-spectrum empirical antibiotics is very common, but the application of ADE is rather disappointing. ADE can reduce the use of anti-bacterial drugs against multi-drug resistant bacteria without significant adverse effects on prognosis in children with sepsis.

Abstract
Abstract
It has been recognized that ultra-high strength and high modulus ultra-highly drawn Polyethylene (PE) fiber is produced from the formation of extended chain crystal. Nevertheless, whether extended chain crystal exists in gel spinning ultra-highly drawn PE fiber is still an unsettled question. In this work, decalin was adopted as a solvent for PE gel spinning. By means of thermal analysis, X-ray diffraction methods etc, the existence of extended chain crystal was explored. Reasons for confusion in previous studies of this problem were discussed.
In PE fiber from 3 wt-°/o dope, extended chain crystal starts to form during draw ratios over 20. When draw ratio equals 42, the content of extended chain crystal roughly equals that of folded chain crystal. The melting point of extended chain crystal is 6°C higher than that of folded chain crystal. They are 145.5° C and 150° C to 152.5° C respectively. The latter would slightly rise with arise of draw ratio.
Multi-crystallization behavior of annealed PE fiber was determined and discussed. It was also confirmed that there is a linear logarithm relationship between thermal shrinkage (internal stresses) and fiber moduli.

Abstract
Fructose (Fru) content is a key determinant of fruit sweetness and quality. An F1 hybrid population of the apple cultivars 'Honeycrisp' × 'Qinguan' was used to investigate the quantitative trait locus (QTL) regions and genes controlling Fru content in fruit. A stable QTL on linkage group (LG) 01 in 'Honeycrisp' was detected on the single nucleotide polymorphism (SNP) genetic linkage maps. In this region, a sorbitol dehydrogenase (SDH) gene, MdSDH2, was detected and showed promoter variations and differential expression patterns between 'Honeycrisp' and 'Qinguan' fruits as well as their hybrids. A SNP variant (A/G) in the MdSDH2 promoter region (SDH2p-491) affected the binding ability of the transcription factor MdABI3, which can affect the expression of MdSDH2. Promoter sequences with an A nucleotide at SDH2p-491 had stronger binding affinity for MdABI3 than those with a G. Among 27 domesticated apple cultivars and wild relatives, this SNP (A/G) was associated with Fru content. Our results indicate that MdSDH2 can alter Fru content as the major regulatory gene and that ABA signaling might be involved in Fru content accumulation in apple fruit.

Abstract
The types and proportions of soluble sugar and organic acid in fruit significantly affect flavor quality. However, there are few reports on the crosstalk regulation between metabolism of organic acid and sugar in fruit. Here, we found that the overexpression of cytoplasmic malate dehydrogenase genes (MdcyMDHs) not only increased the malate content but also increased the sucrose concentration in transgenic apple calli and mature fruit. Enzyme activity assays indicated that the overexpression of MdcyMDH1 and MdcyMDH5 enhanced sucrose phosphate synthase (SPS) activity in transgenic materials. RNA-seq and expression analysis showed that the expression levels of SPS genes were up-regulated in MdcyMDH1-overexpressed apple fruit and MdcyMDH5-overexpressed apple calli. Further study showed that the inhibition of MdSPSB2 or MdSPSC2 expression in MdcyMDH1 transgenic fruit could reduce or eliminate, respectively, the positive effect of MdcyMDH1 on sucrose accumulation. Moreover, some starch cleavage-related genes (MdBAM6.1/6.2, MdBMY8.1/8.2, MdISA1) and the key gluconeogenesis-related phosphoenolpyruvate carboxykinase MdPEPCK1 gene were significantly up-regulated in the transcriptome differentially expressed genes of mature fruit overexpressing MdcyMDH1. These results indicate that alteration of malate metabolism mediated by MdcyMDH might regulate the expression of MdSPSs and SPS activity via affecting starch metabolism or gluconeogenesis, and thus accelerate sucrose synthesis and accumulation in fruit.

Abstract
Background Approximately 2%-8% of non-small-cell lung cancer (NSCLC) harbors concurrent epidermal growth factor receptor (EGFR) sensitizing mutation and mesenchymal–epithelial transition factor (MET) amplification prior to EGFR-tyrosine kinase inhibitor (EGFR-TKI) therapy. This study aimed to investigate the optimal first-line therapeutic options for patients with concurrent EGFR-mutant, MET-overexpressed/amplified advanced NSCLC. Methods A total of 104 treatment-naïve patients with EGFR-mutant de novo MET-overexpressed advanced NSCLC were identified using immunohistochemistry and stratified to four groups according to treatment regimen: EGFR-TKI monotherapy (n = 48), EGFR-TKI combined with either crizotinib (n = 9) or chemotherapy (n = 12), and chemotherapy (n = 35). A subpopulation of 28 patients was also tested with next-generation sequencing (NGS). Objective response rate (ORR) and progression-free survival (PFS) outcomes were analyzed according to treatment strategies and molecular features. Results All the patients (n = 104) achieved ORR of 36.5% and median PFS (mPFS) of 7.0 months. Baseline clinicopathologic characteristics were similar among the four treatment groups. Compared with chemotherapy, EGFR-TKI monotherapy or EGFR-TKI combination therapy achieved significantly higher ORR (P < 0.001) and longer mPFS (P = 0.003). No ORR or PFS difference was observed between EGFR-TKI monotherapy and combination therapy. In the NGS-identified population (n = 28), patients who received EGFR-TKI plus crizotinib (n = 9) achieved similar ORR (88.9% versus 57.9%, P = 0.195) and mPFS (9.0 versus 8.5 months, hazard ratio 1.10, 95% confidence interval 0.43-2.55, P = 0.45) than those who received EGFR-TKI monotherapy (n = 19), regardless of MET copy number status. Grade 3/4 rashes were significantly more among patients who received EGFR-TKI plus crizotinib (P = 0.026). Conclusions Our findings provided clinical evidence that patients with concurrent EGFR sensitizing mutation and de novo MET amplification/overexpression could benefit from first-line EGFR-TKI monotherapy. Concomitant EGFR sensitizing mutation and MET overexpression/amplification were detected in 2.6% of lung cancer patients. EGFR-TKI monotherapy elicited a higher response rate and longer PFS than chemotherapy. EGFR-TKI with or without crizotinib elicited comparable PFS regardless of MET copy number. EGFR-TKI monotherapy achieved lower number of grade 3/4 adverse events than EGFR-TKI plus crizotinib.

Abstract
Objective: The results of syphilis antibody screening in Peking University Third Hospital from 2016 to 2020 were analyzed,to explore the characteristics of sex, age and distribution of patients with positive syphilis antibody. Methods: A retrospective study was conducted to collect the results of syphilis antibody in outpatients and inpatients of Peking University Third Hospital from 2016 to 2020. Syphilis antibodies were screened in 626 528 patients aged 1-98 years, 4 232 were retested positive by TPPA test, including 2 132 males (50.4%) and 2 100 females (49.6%). Chemiluminescence immunoassay (CMIA) was used for syphilis antibody screening, and Treponema pallidum particle agglutination (TPPA) test was used for reexamination. SPSS20.0 data statistical analysis software was used to analyze the detection rate, age, sex, department and clinical diagnosis of patients with positive syphilis antibody by χ² test. Results: Among 626 528 patients who were positive for treponema pallidum antibody screening, 4 232 were retested positive by TPPA test, accounting for 0.68% of the total number of patients tested. The number of syphilis tests increased year by year, however the positive detection rate decreased. The positive detection rate of syphilis antibody in 2020 decreased by 18.9% compared with 2016. The positive rate of syphilis antibody in male patients was higher than that in female patients, accounting for 0.80% and 0.59% of the total number of patients tested respectively. The positive rate of syphilis antibody of different genders increased with age, the total positive rate of 0-20, 21-40, 41-60, 61-80,>80 years old were 0.15%, 0.45%, 0.95%, 1.07% and 1.41%, respectively. While the increase rate of males was higher than that of females. The positive rate of male over 80 years old was 18.13 times of the group of 0-20 years old, and 5.54 times in women. The top 6 departments with positive syphilis antibody detection rate were emergency department, oncology department, respiratory department, geriatrics department, endocrinology department and neurology department, and the positive rates were 1.79% (104/5 810),1.46% (55/3 767),1.20% (74/6 167),1.20% (22/1 833),1.10% (32/2 909),1.09% (94/8 624), respectively. From the analysis of clinical diagnosis, the proportion of positive syphilis antibody in infertile patients (0.64%, 672/104 911) was higher than that in naturally conceived patients (0.10%, 24/23 969). Conclusions: From 2016 to 2020, the positive detection rate of syphilis antibody in Peking University Third Hospital decreased year by year. However, the positive detection rate increased with the age of patients. The positive rate of syphilis antibody in male was higher than that in female. The positive rate of syphilis antibody in pregnant women was lower than that in infertile patients.
