Abstract
Background:Familial cold autoinflammatory syndrome 3 (FCAS3) is an autoinflammatory disease (AID) caused by mutation of the PLCG2 gene, which has not been reported in China. We will report 2 cases of Chinese FCAS3 patients with no claimed family history, but we found the same mutations in a parent during their genetic analysis. After further inquiry of the parent’s medical history, we confirmed that actually, they were two FCAS3 families. Through a literature review, we found that the clinical features of Chinese patients are milder than foreign countries, and their symptoms are concealed and may be ignored, resulting in mistakes in family history collecting.Objectives:To summarize the genetic and clinical features of Chinese FCAS3 patients and to provide diagnostic recommendations for the disease.Methods:Two suspected AID children with recurrent fever and urticaria were enrolled in this study. Clinical data and family history were collected, and genetic analysis was performed by next-generation sequencing (PID panel or WES) and Sanger-based validation. Literature was reviewed from PubMed, CNKI, and Wanfang Database.Results:The two children were both diagnosed to be FCAS3 with PLCG2 mutation. The clinical manifestations of 2 children were recurrent fever, urticaria, and increased ESR and CRP. Case 1 has a paternal, and Case 2 has a maternal heterozygous mutation in the PLCG2 gene, while both had claimed without a family history. Further inquiry showed the two parents used to have a fever with urticaria. By comparing with foreign literature, we found our patients were milder than abroad patients. Large fragment deletions were relatively more common in foreign patients.Conclusion:We reported the case of FCAS3 in China for the first time. Their genotype and phenotype were different from foreign patients. Their symptoms are mild, and heterozygous mutations are more common than foreign patients, which are the main differences. The difference in mutation type may be the reason for different clinical manifestations. Besides, both two families showed a trend of more severe clinical features in the next generation. As the symptoms of the elders were not obvious and may be ignored, it caused trouble for the genetic diagnosis. Therefore, family history should be collected carefully. For rashes and fevers, which are not too severe in overall symptoms, care should be taken about the possibility of AIDs. Genetic testing can help to make a definite diagnosis.Table 1.Descriptive charecteristics of the patients with FMF, n=474VariableCompliant(n=230)Noncompliant (n=244)P valueGender of patient (F)142(61.7)147(60.2)0.73Age, years*35(28-42.5)34(27-44.2)0.88Being Married152(66.1)146(59.8)0.15Disease duration, years*22(14-31)22(15-31)0.71Number of index flare*within last 12-month6.7(1-10)5(3-10)<0.001Family historyof parents54(23.5)39(16.0)0.04Family historyof sibling73(32.9)102(43.4)0.02Comorbid disease presence73(31.7)55(22.5)0.02Treatment<0.001Colchicine230 (94.1)180(78.6)Anakinra&Canakinumab134(5.3)49(21.4)Colchicine response presence127(55.2)126(52.3)0.52Drug using except FMF74(32.2)44(18.0)<0.001Presence of 2 attacks except fever90 (39.1)68(27.9)0.009Chronic peripheral arthritis16(7.0)7(2.9)0.03Amyloidosis18(7.8)9(3.7)0.05Proteinuria23(10.8)8(3.6)0.004Adequate medical care161(70.0)132(54.8)<0.001ISSF severity score*3(2-4)3(2-4)0.02ADDI index*1(0-1)1(0-1)0.05References:[1]Pathak S, Mcdermott M F, Savic S.

Abstract
The trivalent seasonal influenza vaccine was the only approved and available vaccine during the 2016–2018 influenza seasons. It did not include the B/Yamagata strain. In this study, we report an acute respiratory disease outbreak associated with influenza B/Yamagata infections in Guangzhou, Southern China (January through March, 2018). Among the 9914 patients, 2241 (22.6%) were positive for the influenza B virus, with only 312 (3.1%) positive for the influenza A virus. The influenza B/Yamagata lineage dominated during this period in Southern China. The highest incidence of influenza A virus infection occurred in the children aged 5–14 years. In contrast, populations across all age groups were susceptible to the influenza B virus. Phylogenetic, mutations, and 3D structure analyses of hemagglutinin (HA) genes were performed to assess the vaccine-virus relatedness. The recommended A/H1N1 vaccine strain (A/Michigan/45/2015) during both 2017–2018 and 2018–2019 was antigen-specific for these circulating isolates (clade 6B.1) in Spring 2018. An outbreak of influenza B/Yamagata (clade 3) infections in 2018 occurred during the absence of the corresponding vaccine during 2016–2018. The recommended influenza B/Yamagata vaccine strain (B/Phuket/3073/2013) for the following season (2018–2019) was antigen-specific. Although there were only a few influenza B/Victoria infections in Spring 2018, five amino acid mutations were identified in the HA antigenic sites of the 19 B/Victoria isolates (clade 1A), when compared with the 2016–2018 B/Victoria vaccine strain. The number was larger than expected and suggested that the influenza B HA gene may be more variable than previously thought. One of the mutations (K180N) was noted to likely alter the epitope and to potentially affect the viral antigenicity. Seven mutations were also identified in the HA antigenic sites of 2018–2020 B/Victoria vaccine strain, of which some or all may reduce immunogenicity and the protective efficacy of the vaccine, perhaps leading to more outbreaks in subsequent seasons. The combined epidemiological, phylogenetic, mutations, and 3D structural analyses of the HA genes of influenza strains reported here contribute to the understanding and evaluation of how HA mutations affect vaccine efficacy, as well as to providing important data for screening and selecting more specific, appropriate, and effective influenza vaccine candidate strains.

Abstract
Objective: To study the bacterial microleakage at the interface between dental implant and abutment in rats. Methods: Under aseptic conditions, suspension of 0.25 μl of Porphyromonas gingivalis (Pg) (10(9) CFU/ml) was added into the customized implant. After the abutment was connected, the suspension was cultured in an Ep (eppendorf) tube containing 1 ml brain heart infusion (BHI) culture medium. After 7 days and 14 days, the liquid in the Ep tube was taken and inoculated, and the growth of bacteria was observed. Six male SD rats with 12 implants were divided into experimental group (4 implants), negative control group (4 implants) and blank control group (4 implants). All 6 rats had two implants implanted in their bilateral upper jaws. During the second operation, suspension of 0.25 μl Pg (10(9) CFU/ml) was added to the inner part of the implant of the experimental group, culture solution of 0.25 μl was added to the control group and nothing was added to the blank control group. The amount of Pg and total bacteria in each group were evaluated by quantitative real-time PCR (qPCR). The inflammatory cell infiltrate in the peri-implant mucosa was evaluated histomorphometrically. Results: The in vitro model directly verified the presence of bacterial microleakage at implant-abutment interface (IAI), and the animal model confirmed the existence of microleakage through the infiltrate of inflammatory cells near the micro-gap in the experimental group indirectly. In vitro experiments found that Pg had penetrated from the implant within a week by observation and culture. In animal study, the presence of 10(2)-10(4) Pg was detected in the experimental group and it was not detected in the negative control group and the blank control group. At the same time, under the light microscope, in the experimental group, there were inflammatory cells aggregation in the connective tissue around the micro-gap and the density of inflammatory cells gradually decreased from the micro-gap to coronal and the apical of the connective tissue, while there were only scattered inflammatory cells in the connective tissue around the blank control group and the negative control group. In the experimental group, inflammatory cells density in area of 0.25-0.50 mm, 0-0.25 mm coronal to the micro-gap and 0-0.25 mm, 0.25-0.50 mm apical to the mico-gap was respectively, 976 (655), 1 673 (1 245), 2 267 (819) and 895 (162) cells/mm(2),which was significantly more than the blank control group in the corresponding position [respectively 201 (180), 321 (351), 309 (236) and 218 (272) cells/mm(2)] (P<0.05). Conclusions: Pg in the dental implants of rats can be found in the microleakage through implant-abutment interface, and cause the soft tissue inflammation around the implant, and the inflammation has certain distribution characteristics.

Abstract
The dynamic behaviors of a domain wall (DW) pinned by a notch pair or a single notch with different notch depths are studied. It is found that, in a relatively large current density range, the oscillation frequency of the DW becomes frozen and independent of current density when pinned by a notch pair with a notch depth larger than 12 nm. The current density range for freezing the frequency can be tuned by the notch depth. A chain of notch pairs is designed to introduce more pinned DWs into the nanowire. By increasing the number of DWs and applying a proper magnetic field, the oscillation amplitude can be greatly enhanced. Our finding suggests that nanowires with a series of deep notch pairs may have an important application in the development of DW based spin-transfer nano-oscillators with a high tolerance for current fluctuation.

Abstract
Objective:To study whether modified transseptal suturing could be an alternative to packing after septoplasty. Method:We conducted a prospective randomized controlled trial. The study involved 40 patients who underwent septoplasty. Patients were randomly divided into two groups, one with anterior nasal packing and the other with modified transseptal suturing. Patients were asked to record their subjective discomfort levels on a visual analogue scale(VAS) during 48 h postoperatively. Both groups were compared for VAS, postoperative complications 2 weeks after septoplasty through nasal endoscope, the datum of rhinomanometry before surgery and 2 weeks after surgery. Result:The differences of mean postoperative VAS score between two groups were statistically significant(P<0.05). The patients of nasal packing group experienced more discomforts than the other group. No statistically significant between two groups in terms of the datum of rhinomanometry before surgery and 2 weeks after surgery(P>0.05). There were no bleeding, septal hematoma, nasal septum perforation and local infection in all patients 2 weeks after septoplasty. During follow-up 1 case was found with postoperative nasal adhesion, nasal vestibular swelling and fester were seen in two patients and nasal peculiar smell was found in 1 case in nasal packing group. We can find that there were a lot of blood crust in silicone ventilation tube about in 14 patients in packing group. However, the suturing group could see none of the above questions. Conclusion:Modified transseptal suturing is more simple and convenient than nasal packing. In a word, the use of modified transseptal suturing could be an alternative topacking after septoplasty.

Abstract
Growth and fatness traits are complex and economically important traits in the pig industry. The molecular basis underlying porcine growth and fatness traits remains largely unknown. To uncover genetic loci and candidate genes for these traits, we explored the GeneSeek GGP Porcine 80K SNP chip to perform a GWAS for seven growth and fatness traits in 365 individuals from the Sujiang pig, a recently developed breed in China. We identified two, 17, one and 11 SNPs surpassing the suggestively significant threshold (P < 1.86 × 10-5 ) for body weight, chest circumference, chest width and backfat thickness respectively. Of these SNPs, 20 represent novel genetic loci, and five and four SNPs were respectively associated with chest circumference and backfat thickness at a genome-wide significant threshold (P < 9.31 × 10-7 ). Eight SNPs had a pleiotropic effect on both chest circumference and backfat thickness. The most remarkable locus resided in a region between 72.95 and 76.27 Mb on pig chromosome 4, harboring a number of previously reported quantitative trait loci related to backfat deposition. In addition to two reported genes (PLAG1 and TAS2R38), we identified four genes including GABRB3, ZNF106, XKR4 and MGAM as novel candidates for body weight and backfat thickness at the mapped loci. Our findings provide insights into the genetic architecture of porcine growth and fatness traits and potential markers for selective breeding of Chinese Sujiang pigs.

Abstract
OBJECTIVES Cognitive frailty was notable target for the prevention of adverse health outcomes in future. The goal of this study was to use a population-based survey to investigate cognitive frailty phenotypes and potentially sociodemographic factors in elderly Chinese individuals. DESIGN Cross-sectional study. SETTING General community. PARTICIPANTS A total of 5328 elderly adults (aged 60 years or older, mean age 71.36 years) enrolled in the Shanghai study of health promotion for elderly individuals with frailty. MEASUREMENTS The 5-item FRAIL scale and the 3-item Rapid Cognitive Screen tools were used to assess physical frailty and cognitive impairment, including dementia or mild cognitive impairment (MCI). Physical frailty was diagnosed by limitations in 3 or more of the FRAIL scale domains and pre-physical frailty by 1-2 limitations. Subjective cognitive decline (SCD) and pre-MCI SCD, was diagnosed with two self-report measures based on memory and other cognitive domains in elderly adults. RESULTS Of the participating individuals, 97.17% (n= 5177, female 53.4%) were eligible. Notably, 9.67%, 41.61% and 35.20% of participants were MCI, SCD and pre-MCI SCD; 35.86% and 4.41% exhibited physical pre-frailty and frailty; and 19.86% and 6.30% exhibited reversible and potential reversible cognitive frailty. Logistic regression analyses indicated that physical frailty phenotypes were significantly associated with MCI with SCD, and pre-MCI with SCD. Older single females with a high education level were more likely to exhibit the reversible cognitive frailty; and younger elderly individuals with a middle education level were at lower risk for potentially reversible cognitive frailty. CONCLUSIONS The prevalence of pre-physical and reversible cognitive frailty was high in elderly individuals and age was the most significant risk factor for all types of frailty phenotypes. To promote the rapid screening protocol of cognitive frailty in community-dwelling elderly is important to find high-risk population, implement effective intervention, and decrease adverse prognosis.

Abstract
BACKGROUND Myokine Irisin has been proposed to regulate metabolic homeostasis, which is related to chronic diseases or physical activity. However, whether irisin levels in paired cerebrospinal fruid (CSF), plasma and their ratio of inpatients, could use as biomarkers, and be independently related to the varying physical dysfunction, muscle wasting severity and chronic diseases with varying severe degrees, remain largely elusive. METHODS We conducted an observational study to assess the independent associations between irisin levels in paired cerebrospinal fruid (CSF), plasma and their ratio, and the independence in activities of daily life (ADLs), muscle wasting severity and chronic diseases with varying severe degrees among elderly Chinese in-patient subjects. RESULTS Among 217 inpatients in surgery wards with a mean age of 68.07 years (±15.94years), 31.3% of women and 68.7% of men were included in the study. Bivariate correlation analysis showed that Log transformed CSF and plasma irisin levels and their ratio were potential associated with age, fat%, muscle wasting time, ADLs, number of multimorbidity, the severity of bone mass loss and anemia. Regression models analysis indicated that CSF and plasma irisin levels and their ratio in inpatient individuals were independently associated with the independence in ADLs. Plasma irisin levels were independently related to the change of muscle wasting use. CONCLUSIONS Collectively, the evaluation of paired plasma and CSF irisin levels, and their ratio in in-patient individuals is intriguing candidates for the susceptibility of the independence in ADLs. Plasma irisin levels were positively associated with indepedence in ADLs, negatively related to muscle wasting severity, and could use as biomarkers for muscle wasting severity.

Abstract
OBJECTIVE Mammalian target of rapamycin (mTOR) can negatively regulate cell autophagy, while its expression and activity are associated with the pathogenesis of osteosarcoma. MicroRNA 100 (MiR-100) down-regulation is associated with the pathogenesis and chemo-sensitivity of osteosarcoma. Bioinformatics analysis revealed the targeted relationship between miR-100 and the 3'-UTR of mTOR. We investigate the role of miR-100 in affecting mTOR expression, osteosarcoma cell autophagy, and sensitivity to cisplatin. PATIENTS AND METHODS MiR-100, mTOR, and Beclin-1 expressions in osteosarcoma tissue and normal control were compared. The relationship between miR-100 and mTOR was verified by dual luciferase assay. MiR-100, mTOR, and Beclin-1 levels in MG-63 cells and MG-63/DDP cells were tested. Cell apoptosis was determined by using flow cytometry. Cell malignancy was evaluated by colony formation assay. RESULTS MiR-100 and Beclin-1 significantly declined, while mTOR significantly increased in osteosarcoma tissue compared with that of normal tissue (p<0.05). MiR-100 targeting significantly inhibited mTOR expression compared to that of untreated (p<0.05). MiR-100 expression was down-regulated and mTOR level was elevated in MG-63/DDP cells compared with MG-63 cells (p<0.05). MG-63/DDP cells exhibited reduced cell autophagy and apoptosis, and enhanced colony formation induced by DDP. MiR-100 mimic and/or small interfere mTOR (si-mTOR) significantly promoted Beclin-1 expression, cell autophagy, and cell apoptosis, while attenuated colony formation. CONCLUSIONS MiR-100 declined, while mTOR up-regulated in osteosarcoma tissue. MiR-100 up-regulation enhanced cell autophagy and apoptosis induced by cisplatin via targeted inhibiting of mTOR.

Abstract
Frameworks for limiting ecosystem exposure to excess nutrients and acidity require accurate and complete deposition budgets of reactive nitrogen (Nr). While much progress has been made in developing total Nr deposition budgets for the U.S., current budgets remain limited by key data and knowledge gaps. Analysis of National Atmospheric Deposition Program Total Deposition (NADP/TDep) data illustrates several aspects of current Nr deposition that motivate additional research. Averaged across the continental U.S., dry deposition contributes slightly more (55%) to total deposition than wet deposition and is the dominant process (>90%) over broad areas of the Southwest and other arid regions of the West. Lack of dry deposition measurements imposes a reliance on models, resulting in a much higher degree of uncertainty relative to wet deposition which is routinely measured. As nitrogen oxide (NOx) emissions continue to decline, reduced forms of inorganic nitrogen (NHx = NH3 + NH4+) now contribute >50% of total Nr deposition over large areas of the U.S. Expanded monitoring and additional process-level research are needed to better understand NHx deposition, its contribution to total Nr deposition budgets, and the processes by which reduced N deposits to ecosystems. Urban and suburban areas are hotspots where routine monitoring of oxidized and reduced Nr deposition is needed. Finally, deposition budgets have incomplete information about the speciation of atmospheric nitrogen; monitoring networks do not capture important forms of Nr such as organic nitrogen. Building on these themes, we detail the state of the science of Nr deposition budgets in the U.S. and highlight research priorities to improve deposition budgets in terms of monitoring and flux measurements, leaf- to regional-scale modeling, source apportionment, and characterization of deposition trends and patterns.

Abstract
Background Acute coronary syndrome (ACS) is the leading cause of death in developing and developed countries, yet assessing the risk of its development remains challenging. Several lines of evidence indicate that small, dense low‐density lipoproteins (sd‐LDL) are associated with increased cardiovascular disease risk. We aim to evaluate sd‐LDL concentration for predicting the risk of ACS in Chinese population. Methods Baseline characteristics of 121 patients with ACS and 172 healthy controls were obtained. Plasma sd‐LDL‐C was measured using homogeneous assay, and the proportion of sd‐LDL‐C in LDL‐C was detected. Results There was gender and age effect on the sd‐LDL‐C concentration and sd‐LDL‐C/LDL‐C ratio among healthy subjects. Elevated sd‐LDL‐C concentrations and sd‐LDL‐C/LDL‐C ratio were observed in ACS patients with unstable angina pectoris (UAP), non–ST‐segment elevation myocardial infarction (STEMI), and ST‐segment elevation myocardial infarction (NSTEMI) compared with healthy controls (P < .05); however, there were no differences among ACS groups. According to Pearson's correlation coefficient analyses, sd‐LDL‐C concentration and sd‐LDL‐C/LDL‐C ratio were positively correlated with triglyceride (TG) and LDL‐C concentrations (P < .05) and negatively correlated with high‐density lipoprotein (HDL) concentration (P < .05). Based on the receiver operating characteristic (ROC) curves, the cutoff values of sd‐LDL‐C and sd‐LDL‐C/LDL‐C ratio for the prediction of ACS were 1.06 mmol/L and 34.55%, respectively. Multivariate logistic regression analysis demonstrated that the sd‐LDL‐C/LDL‐C ratio, but not sd‐LDL‐C concentration, was significantly associated with ACS events [OR (95% CI): 1.24, 1.11‐1.38, P < .001]. Conclusions The sd‐LDL‐C/LDL‐C ratio may be associated with an increased risk of developing ACS in Chinese population.

Abstract
Objective: To investigate the expression of nucleolar and spindle-associated protein 1 (NUSAP1) in non-small cell lung cancer (NSCLC) and analyze its relationship with the prognosis of NSCLC patients. Methods: Real-time fluorescent quantitative PCR and immunohistochemical staining were performed to determine the expression of NUSAP1 in NSCLC tissues and adjacent tissues collected from hospital. The relationship between NUSAP1 expression and prognosis of NSCLC patients was analyzed by online database. Results: The expression level of NUSAP1 mRNA in tumor tissues was significantly higher than that of adjacent tissues (P<0.05). The high expression rate of NUSAP1 protein in NSCLC tissues was 58.0% (29/50), significantly higher than 22.0% (11/50) of adjacent tissues (P<0.05). The high expression of NUSAP1 protein in NSCLC tissues was closely correlated with tumor size, lymph node metastasis and TNM stage (P<0.05), but was not related to age and gender. The data showed that the expression level of NUSAP1 mRNA was inversely associated with the overall survival (OS) of NSCLC patients (P<0.001). The expression of NUSAP1 mRNA was significantly correlated with the pathological grade, clinical stage, gender, chemotherapy, smoking history, and histological type of NSCLC patients (P<0.05). Conclusions: The expression of NUSAP1 is up-regulated in NSCLC, which is correlated with the growth and development of NSCLC and prognosis of the patients. These results indicate that NUSAP1 can be used as a potential prognostic marker for NSCLC.

Abstract
Abstract
Background
Direct oral anticoagulants (DOACs) are at least as effective as low-molecular weight heparins (LMWH) at preventing recurrence after cancer-associated venous thromboembolism (CA-VTE). DOACs are also oral and far less costly, but they may confer a higher bleeding risk than LMWH.
Purpose
To estimate the cost-effectiveness of DOACs and LMWHs for CA-VTE.
Methods
We developed a health state transition model to estimate recurrent VTE, bleeding events, quality-adjusted life years (QALY), and direct healthcare costs (2018 United States dollars) associated with DOACs vs. LMWH use. The model had four states: (1) long-term anticoagulation (first 3 months after VTE), (2) extended anticoagulation (more than 3 months after VTE), (3) off anticoagulants, and (4) death. We used a United States healthcare sector perspective, 3-month cycle length, and 1-year time horizon. Event probabilities were derived from the Hokusai Cancer VTE trial and other literature. Event and medication costs were obtained from national sources. We used a threshold of less than $50,000 per QALY gained to define cost-effectiveness.
Results
Compared to LMWH, DOACs were less costly (mean costs: $8,477 vs. $33,917 per year) and similarly effective (mean QALY: 0.616 vs. 0.622). The incremental cost-effectiveness ratio was $4,479,374 per QALY gained with LMWH, indicating that DOACs are cost-effective (Table 1). In threshold analyses, LMWH therapy only became cost-effective when DOAC recurrent VTE risk increased to at least 72% (relative risk vs. LMWH, 6.19) or DOAC clinically relevant bleeding increased to at least 39% (relative risk vs. LMWH, 10.09).
Scenarios Recurrent VTE, % Major bleed, % Mean difference DOAC − LMW ICER DOAC LMWH Relative Risk DOAC LMWH Relative Risk Cost QALY Base case 8.1 11.6 0.71 6.8 4.0 1.75 −$25,440 (−26,496, −24,274) −0.006 (−0.019, 0.008) $4,479,374 DOAC outcome rate threshold at which LMWH becomes cost-effective* Recurrent VTE 71.5 11.7 6.19 – – – −$6,064 (−7,534, −4,627) −0.121 (−0.136, −0.108) $49,886 Major Bleed – – – 38.9 4.0 10.09 −$2,192 (−3,400, −704) −0.044 (−0.056, −0.030) $49,878 DOAC = direct oral anticoagulant, ICER = incremental cost-effectiveness ratio, LMWH = low-molecular-weight heparin, VTE = venous thromboembolism. Values are mean (95% Uncertainty Interval). Uncertainty was derived from 1,000 stochastic model iterations. *Represents the minimum increased risk with DOAC that would result in LMWH achieving an ICER <$50K per QALY gained.
Conclusion
In this simulation study, DOACs were a cost-effective oral alternative to LMWH for the treatment of CA-VTE. For LMWH to be cost-effective, DOAC event rates needed to be far higher than what is likely to be observed in clinical practice.
