Abstract
Objective: To explore the clinical epidemiological characteristics of respiratory syncytial virus in children in Hubei Province from 2020 to 2023. Method: A single-center and cross-sectional study was used to analyze the clinical data of 3 271 children with respiratory syncytial virus infection in Wuhan Children's Hospital affiliated to Huazhong University of Science and Technology from July 1, 2020 to June 30, 2023. Nonparametric rank sum test and χ2 test were used for comparative analysis. Results: From July 1, 2020 to June 30, 2023, a total of 25 583 children were included in the analysis, of which 3 271(12.8%) children infected RSV. The detection rate was 16.3% in 2020-2021, 14.7% in 2021-2022 and 9.1% in 2022-2023. The detection rate decreased year by year (χ2=222.054, P<0.05). From 2020 to 2023, there was an anti-seasonal epidemic of RSV in spring and autumn. The detection rate of RSV in infants under 1 year old was the highest, but the median ages of RSV positive children increased (H=140.575, P<0.05). Pneumonia was the main clinical manifestation of RSV respiratory tract infection. Conclusion: The epidemiological characteristics of RSV in children in Hubei Province were different from those before. From 2020 to 2023, the detection rate of RSV decreased year by year. Besides winter, the prevalence of RSV could also be seen in spring and autumn. The median age of children infected with RSV increased after the epidemic. Pneumonia was the main clinical manifestation after RSV infection.

Abstract
Defining monogenic drivers of autoinflammatory syndromes elucidates mechanisms of disease in patients with these inborn errors of immunity and can facilitate targeted therapeutic interventions. Here, we describe a cohort of patients with a Behçet's- and inflammatory bowel disease (IBD)-like disorder termed "deficiency in ELF4, X-linked" (DEX) affecting males with loss-of-function variants in the ELF4 transcription factor gene located on the X chromosome. An international cohort of fourteen DEX patients was assessed to identify unifying clinical manifestations and diagnostic criteria as well as collate findings informing therapeutic responses. DEX patients exhibit a heterogeneous clinical phenotype including weight loss, oral and gastrointestinal aphthous ulcers, fevers, skin inflammation, gastrointestinal symptoms, arthritis, arthralgia, and myalgia, with findings of increased inflammatory markers, anemia, neutrophilic leukocytosis, thrombocytosis, intermittently low natural killer and class-switched memory B cells, and increased inflammatory cytokines in the serum. Patients have been predominantly treated with anti-inflammatory agents, with the majority of DEX patients treated with biologics targeting TNFα.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
OBJECTIVE Brainstem tumors present a significant challenge in surgical treatment, and the prognostic factors in children are lacking. This study aimed to investigate clinical characteristics and prognostic factors of surgical treatment in children with brainstem tumors. PATIENTS AND METHODS 50 children with brainstem tumors who underwent surgical treatment, including frameless- or frame-based stereotactic biopsy and resection, were included and followed up for clinical and biological analysis. Factors of outcomes were assessed by univariate and multivariate analysis. RESULTS 27 cases (54.0%) underwent resection in all children with brainstem tumors. The rate of resection reached as high as 81.8% in children with non-diffuse intrinsic pontine glioma (DIPG), while in children with DIPG, biopsy was performed in the majority, and resection was obtained in the minority with focal necrosis. A rare complication was found following the surgery. Multivariate analysis considered World Health Organization (WHO) grade 3-4, with hazard ratio (HR)=4.48, 95% confidence interval (CI) of 2.84-8.69, p=0.001, H3K27M mutation (HR=2.50, 95% CI 1.73-5.69, p=0.015), and hydrocephalus (HR=2.17, 95% CI 1.08-5.32, p=0.014) as independent adverse prognostic factors. For Kaplan-Meier analysis, children with WHO grade 3-4, Ki-67 LI ≥ 20%, TP53 mutation, H3K27M mutation, DIPG, and hydrocephalus had significantly decreased overall survival (OS). CONCLUSIONS A high rate of resection has been obtained in non-DIPG, and surgical intervention is remarkably safe and efficient for children with brainstem tumors. WHO grade 3-4, H3K27M mutation, and hydrocephalus indicate poor prognosis in children with brainstem tumors.

Abstract
BACKGROUND The aim of this study was to explore the safety and efficacy of a novel mini-open sublay hernioplasty with D10 mesh for primary lumbar hernias. METHODS This retrospective study included 48 patients with primary lumbar hernias who underwent mini-open sublay hernioplasty with D10 mesh from January 2015 to January 2022 in our hospital. Observation indicators were intraoperative measured diameter of hernia ring defect, operation time, length of hospital stay, postoperative follow-up, complications, postoperative visual analog scale (VAS) score, chronic pain. RESULTS The operations were completed successfully in all 48 cases. The mean diameter of hernia ring was 2.66 ± 0.57 cm (range 1.5-3.0 cm), the mean operation time was 41.54 ± 13.21 min (range 25-70 min), the intraoperative blood loss was 9.89 ± 6.16 ml (range 5-30 ml), and the mean hospital stay was 3.14 ± 1.53 days (range 1-6 days). The mean preoperative and postoperative VAS scores at 24 h were 0.29 ± 0.53 (range 0-2) and 2.52 ± 0.61 (range 2-6), respectively. All cases were followed-up for 53.4 ± 24.3 months (range 12-96 months) without seroma, hematoma, incision or mesh infection, recurrence, and obvious chronic pain. CONCLUSION A novel mini-open sublay hernioplasty with D10 mesh for primary lumbar hernias is safe and feasible. Its efficacy in the short term is favorable.

Abstract
Objective: To analyze the imaging features of cone-beam CT (CBCT) of ameloblastoma (AB), odontogenic keratocyst (OKC) and dentigerous cysts (DC) associated with the mandibular impacted third molars,so as to provide useful information for differential diagnosis of these lesions. Methods: The patients who were with complete clinical data, pathological diagnosis and CBCT images from AB, OKC and DC around the mandibular impacted third molars were collected in Peking University Hospital of Stomatology from August 2016 to December 2021. A total of 109 patients (14 were diagnosed as AB, 23 were diagnosed as OKC and the others were diagnosed as dental cysts) were collected, including 73 males and 36 females. The age ranged from 11 to 70. The analyzed imaging features included location and internal density of the lesions, bone expansion, root resorption of adjacent teeth and types of the impacted teeth. The Chi square test was used to compare the gender of different lesions, and the Fisher's exact test was used to compare imaging features of lesions. When P<0.05, there was a significant difference among the three. Logistic regression analysis was performed to determine the imaging features that significantly contribute to correct imaging diagnosis. Corresponding P-values were calculated for all factors from multivariate models. Results: In the 23 cases of OKC, no special location was observed for the center of the lesion, heterogeneous high-density were seen in 21.7% of the cases, 56.5% of the cases had no significant bone expansion and the impacted teeth were not specially oriented. Among the 14 AB, 7 cases (7/14) were mainly located in the ramus of the mandible, and all cases (14/14) had buccal/lingual expansion of the jaw, 8 cases (8/14) presented root resorption of the adjacent teeth, and mesial impacted mandibular third molar were seen in 6 cases (6/14). Among the 72 DC, 88.9% (64/72) of the cases were mainly limited to the crown of the impacted third molar, 72.2% (52/72) of the cases had no obvious bone expansion, inverted impacted teeth were shown in 56.9% (41/72) of the cases. There was a significant difference among the three groups (χ2=7.30, P=0.026) in gender. AB and odontogenic cyst were more common in men than in women, while the incidence of OKC was roughly equal between men and women.There were significant differences in the location (P<0.001), internal density (P=0.001) of the lesions, bone expansion (P<0.001) and types of the impacted teeth (P<0.001), while no statistical difference was found for root resorption of adjacent teeth (P=0.153). Logistics regression analysis showed that the location of the lesion, internal density, bone expansion, root resorption of adjacent teeth and the types of impacted teeth had significant effects on the accurate diagnosis of the three kinds of lesions. Conclusions: Location, internal density, bone expansion and types of the impacted teeth played an important role in the correct imaging diagnosis. Further analysis indicates that when the classification of impacted teeth and the location of lesions are considered synchronously, DC can be differentiated from AB and OKC.

Abstract
Cruznema velatum isolated from soil in a chestnut orchard located at Guangdong province, China, is redescribed with morphology, molecular barcoding sequences, and transcriptome data. The morphological comparison for C. velatum and six other valid species is provided. Phylogeny analysis suggests genus Cruznema is monophyletic. The species is amphimix, can be cultured with Escherichia coli in 7-9 days from egg to egg-laying adult, and has a lifespan of 11 to 14 days at 20°C. The transcription data generated 45,366 unigenes; 29.9%, 31.3%, 24.8%, and 18.6% of unigenes were annotated in KOG, SwissProt, GO, and KEGG, respectively. Further gene function analysis demonstrated that C. velatum share the same riboflavin, lipoic acid, and vitamin B6 metabolic pathways with Caenorhabditis elegans and Pristionchus pacificus.

Abstract
Patients with DEX (deficiency in ELF4, X-linked) were recently reported by our team and others, and cases are very limited worldwide. Our knowledge of this new disease is currently preliminary. In this study, we described 5 more cases presenting mainly with oral ulcer, inflammatory bowel disease-like symptoms, fever of unknown origin, anemia, or systemic lupus erythematosus. Whole exome sequencing identified potential pathogenic ELF4 variants in all cases. The pathogenicity of these variants was confirmed by the detection of ELF4 expression in peripheral blood mononuclear cells from patients and utilizing a simple IFN-b luciferase reporter assay, as previously reported. Our findings significantly contribute to the current understanding of DEX.

Abstract
The dedicator of cytokinesis 2(DOCK2) protein, an atypical guanine nucleotide exchange factor (GEFs), is a member of the DOCKA protein subfamily. DOCK2 protein deficiency is characterized by early-onset lymphopenia, recurrent infections, and lymphocyte dysfunction, which was classified as combined immune deficiency with neutrophil abnormalities as well. The only cure is hematopoietic stem cell transplantation. Here, we report two patients harboring four novel DOCK2 mutations associated with recurrent infections including live attenuated vaccine-related infections. The patient's condition was partially alleviated by symptomatic treatment or intravenous immunoglobulin. We also confirmed defects in thymic T cell output and T cell proliferation, as well as aberrant skewing of T/B cell subset TCR-Vβ repertoires. In addition, we noted neutrophil defects, the weakening of actin polymerization, and BCR internalization under TCR/BCR activation. Finally, we found that the DOCK2 protein affected antibody affinity although with normal total serum immunoglobulin. The results reported herein expand the clinical phenotype, the pathogenic DOCK2 mutation database, and the immune characteristics of DOCK2-deficient patients.

Abstract
OBJECTIVE Aside from the severity, surgical interventions for the treatment of neurological dysfunctions remain controversial. This study aimed to find factors predicting the benefits of tethered cord syndrome (TCS) surgery. PATIENTS AND METHODS 80 children with TCS were included and followed up for pre- and post-operative factors along with neurophysiological analysis. Outcomes were assessed by univariate and multivariate analysis. RESULTS Surgical treatment not only improved preoperative signs and symptoms in 79% of TCS patients but it showed to be an efficient procedure for the occurrence of future neurological defects. Univariate analysis also revealed that surgical intervention in TCS children (age <1 year) can modulate filar lipoma location and cutaneous abnormalities three months after surgery. Neurophysiological assessment revealed only 5.0% of surgical complications in TCS patients. Two patients had cerebrospinal fluid leakage, and two cases of CNS infection were detected. CONCLUSIONS Surgical intervention is highly recommended for the prevention of neurological deficits in children with TCS. Electrophysiological monitoring revealed rare complications following the surgery.

Abstract
Abstract
Background
30-day rehospitalisation following heart event among acute coronary syndrome (ACS) patients remains high and is largely contributed by poor disease-related knowledge and self-management, especially in the disadvantaged patient groups such as those with low education levels and inadequate health literacy. Traditional patient education methods fail to address these issues.
Purpose
This study aimed to test a unique consumer co-designed discharge education application (app) on patients' knowledge and its acceptability.
Methods
ACS patients (unstable angina, non-STEMI or STEMI) were recruited from Royal Adelaide Hospital at South Australia during admission, provided with the app via tablet for one-month self-delivered education. The app has undergone a rigorous development process with the substantial engagement of consumers (Figure 1). App content includes the Heart Foundation Six Steps to Cardiac Recovery including disease-related knowledge, risk factor management, and ACS responses, assessed at baseline, followed by first use at discharge and one month later. Patients and cardiac nurses rated the acceptability of the app.
Results
Among 22 Participants 81.8% were male (n=18), with a mean age of 59.7 (10.3) years, 45.5% (n=10) had not completed high school and nearly a quarter of the participants had marginal or below marginal health literacy. The diagnosis included STEMI (n=16, 72.7%) and non-STEMI (n=5, 22.7%). The majority of participants underwent percutaneous coronary intervention (PCI) (n=21, 95.5%)
Significant improvements were observed for overall coronary artery disease knowledge at one month (p=0.003) and the exercise and nutrition domains at discharge (p=0.029; p<0.001) and one month (p=0.02; p=0.003) (Figure 2). Significant improvements were also observed for ACS knowledge and beliefs at discharge (p=0.008; p=0.038) and one month (p<0.001; p=0.025) when ACS response attitude was also significantly improved at one month (p=0.036). Overall acceptability was high at 7.7/10 (n=22 nurses) and 8.3/10 (patients). The participants described the app as `clear, simple, easy to understand, as well as stimulating and interactive, better than a live person'.
Conclusion
This novel, self-delivered Avatar-based ACS discharge education App has the potential to provide discharge education for ACS patients even for those who have low education levels or inadequate health literacy. Results need to be confirmed in a randomised controlled trial.

Background/significance
The rapid development of information technology is driving the evolution of choices of modes of delivery of healthcare services. The internet is an extremely powerful tool for accessing information, and communication. However, involvement of patients in the assessment of such an intervention is crucial, and can be achieved through a person-centred approach, utilising a co-design process with the aim to increase intervention usability.
Purpose
To assess the usability of the Country Access to Cardiac Health (CATCH) Web, an interactive web application for cardiac rehabilitation (CR), co-designed with rural and remote Australians, following the co-design development phase.
Methods
The User Experience (UX) Design framework was used to co-design the web portal with CR patients through two rounds of six co-design workshops pre (n=39), and post (n=35). Participants and family members living in rural and remote areas of Australia were invited to participate based on their eligibility for CR as outlined by the National Heart Foundation of Australia. As part of the UX Design Framework the System Usability Scale (SUS) was used to measure objective feedback from participants on the website design. The SUS assesses the three core components of a products usability: effectiveness, efficiency and satisfaction using a 10 question Likert scale. Mean scores were compared between the two rounds of workshops using an independent T-Test. The mean SUS score is categorised into poor to moderate (<68), good (68-80.3) and excellent (>=80.3) and categories were compared between the two rounds of workshops through Chi-Square tests.
Results
The 35 participants in the usability workshops had a mean age of 68.6 (SD 11.2) years and 16 (47%) were female (Table 1). The majority had experienced a myocardial infarction (15, 42.8%) and had hyperlipidemia (17, 50%), heart failure (15, 44%), hypertension (14, 41%), and Type II diabetes (7, 21%). Of these participants 20 (59%) used a smart phone, 18 (58%) had access to the National Broadband Network and 20 (59%) engaged with Facebook. From the first to the second round of workshops, there was an improvement in the mean SUS scores from 66.7 (SD16.8) to 73.6 (SD 21.0); p=0.26. The proportion of participants rating it as good or excellent increased from 48.7 to 65.8%; p=0.11 (Figure1).
Conclusion
The usability testing of the interactive CATCH web application showed an improvement in the SUS rating from poor to moderate in the co-design development phase to good or excellent by most of the participants in the usability testing phase. Usability is closely related to engagement with a digital health intervention. Upcoming evaluation of this intervention will report on clinical outcomes.

Abstract
BACKGROUND There has been a rapid increase in the number of human adenovirus type 7 (HAdV-7) and invasive pulmonary fungal infections (IPFIs) co-infection. METHODS In this study, we included patients with confirmed HAdV-7 infection during the period from 2018 to 2019 to explore clinical characteristics of severe HAdV-7 pneumonia combined with IPFIs. RESULTS Among the 143 patients, 35 cases were co-infected with IPFIs. Others were assigned to the control group (n Z 108). Patients wereprone to be complicated with respiratory failure, heart failure and hemophagocytic syndromein IPFIs group. Thirty-one species of fungi were detected in the IPFIs group, among whichAspergillus was the most common species. Compared to control group, patients had lowerlevels of WBC, CD3þ T lymphocyte counts and CD19þ B lymphocyte counts in IPFIs group. CONCLUSION Aspergillus is the most common species in IPFIs combined with severe HAdV-7 pneumonia. For children with severe HAdV-7 pneumonia who are younger, have a long course of disease, and have been admitted to the ICU, we should predict the occurrence of IPFIs when there is multi-system dysfunction and the reduction of CD3+ T lymphocyte counts and CD19+ B lymphocyte counts in course of their disease.

Abstract
Background:Bullous systemic lupus erythematosus (BSLE) is a rare subtype of systemic lupus erythematosus, accounting for less than 1% of systemic lupus erythematosus (SLE) [1]. It is common in adults aged 20 to 40, with female predominace [2]. Its skin manifestations are mainly tensive blisters, especially involving oral and genital mucosa, Nissl’s sign is mostly negative, blisters break and heal to form pigmentation of varying degrees, leaving no scar. At present, the main treatment is systemic application of corticosteroids combined with immunosuppressants. Here, we report a BSLE who successfully treated with mycophenolate mofetil (MMF) combined with glucocorticoid.ObjectivesTo be vigilant in the early identification of BSLE, and through the treatment experience of this case, it can provide a basis for the use of Mycophanol ester as the preferred drug for the treatment of BSLE in the future.MethodsThe clinical manifestation, laboratory test, treatment, and outcome were described.ResultsA 50-year-old female patient with systemic lupus erythematosus presented with wandering joint pain for 1 year and sporadic patchy erythema on eyelid, hands, and neck for 7 months. There are blisters on part of her erythema and normal skin, about 1mm-15mm in diameter, the blister fluid is cool, fusion is broken, and Nissl’s sign is negative. She suffered from anemia, albuminuria, polyserous effusion and other system damage. Skin histopathology showed mild hyperkeratosis of epidermis, formation of subepidermal blisters and accumulation of a large number of neutrophils; direct immunofluorescence showed that the positive expressions of IgA, IgG and C3 were found in the basement membrane of the skin, leading to a diagnosis of BSLE. In the initial stage, patients were treated with high-dose glucocorticoid (160 mg, qd) combined with immunosuppressants (thalidomide and hydroxychloroquine), but the number of blisters increased. After treatment with MMF (1 g, bid), the skin lesions disappeared, joint pain relieved, anemia was corrected, and polyserous effusion was absorbed. She was followed up for half a year and there was no recurrence.ConclusionPatients with BSLE are often accompanied by multiple system damage [2], so it is critical to correctly identify BSLE and provide appropriate treatment as soon as possible. For patients who do not respond to single glucocorticoid therapy, combined with MMF can be used as the preferred drug for the treatment of BSLE in the future.References:[1] L.

Abstract
BackgroundIguratimod (IGU), as one of the conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), has been approved by National Medical Products Administration (NMPA) to treat Rheumatoid arthritis (RA).ObjectivesThis study aimed to compare the cost-effectiveness of well-established RA therapies using a claims-based algorithm in RA patients.MethodsAn electronic medical record (EMR) database from Zhujiang Hospital was utilized to estimate the cost-effectiveness of medication for RA patients, including IGU with MTX, biological DMARDs (bDMARDs) with MTX, and MTX alone for more than 6 months from 2014 to 2020. Patients who were deemed effective must meet all the following criteria according to the algorithm, high adherence; no bDMARDs or IGU switch or addition; no prescription of new csDMARDs; no increase in dose or frequency of index drug; no new use of chronic glucocorticoids or increase in glucocorticoid dose; and no more than one glucocorticoid injection. Average cost was calculated by summing total cost of effective treatment and dividing by number of patients achieving efficacy in each group.ResultsA total of 263 patients were included in the analysis. Based on a claims-based algorithm, the effective rate was 27.1 % (26/96) for IGU with MTX group, 11.2% (7/62) for bDMARDs with MTX group, and 13.3% (14/105) for MTX alone group, respectively. Average cost of effective treatment was $833.46 for IGU with MTX therapy, $2554.57 for bDMARDs with MTX therapy, and $171.48 for MTX alone (Table 1).Table 1.Effectiveness and Cost per Effectively Treated Patient with RACriteriaAll patients (n=263)IGU with MTX group(n=96)bDMARDs with MTX group (n=62)MTX (n=105)Effectiveness:no. of patients (%)a47(17.87%)26 (27.1%)7 (11.2/%)14 (13.3%)Cost of all RA-related medication per effectively treated patient(SD)$892.75(911.57)$833.46 (252.67)$2554.5 (1273.13)$171.4 (110.33)Average cost of all RA medications postindex (excluding biologic DMARDs) per patient (SD)b$146.38(114.60)$148.81 (123.12)$86.90 (74.53)$171.4 (110.33)Average cost of only biologicDMARDs postindex per patient (SD)b$746.38(926.35)$684.27(188.67)$2468.67(1285.91)/a χ2showed significant difference in percentage effectiveness for the original algorithm (p<0.05).bMedication cost was 2020 U.S. dollars.ConclusionIGU with MTX therapy was revealed to be both effective and modestly priced, which seemed to be a cost-effective strategy for RA therapy and warranted further cost-effectiveness investigation.References[1](2018) [2018 Chinese guideline for the diagnosis and treatment of rheumatoid arthritis].

Abstract
Monogenic autoinflammatory diseases (mAIDs) are a heterogeneous group of diseases affecting primarily innate immunity, with various genetic causes. Genetic diagnosis of mAIDs can assist in the patient's management and therapy. However, a large number of sporadic and familial cases remain genetically uncharacterized. Deficiency in ELF4, X-linked (DEX) is recently identified as a novel mAID. Here, we described a pediatric patient suffering from recurrent viral and bacterial respiratory infection, refractory oral ulcer, constipation, and arthritis. Whole-exome sequencing found a hemizygous variant in ELF4 (chrX:129205133 A > G, c.691 T > C, p.W231R). Using cells from patient and point mutation mice, we showed mutant cells failed to restrict viral replication effectively and produced more pro-inflammatory cytokines. RNA-seq identified several potential critical antiviral and anti-inflammation genes with decreased expression, and ChIP-qPCR assay suggested mutant ELF4 failed to bind to the promoters of these genes. Thus, we presented the second report of DEX.

Abstract
mRNA m6A modification is heavily involved in modulation of immune responses. However, its function in antiviral immunity is controversial, and how immune responses regulate m6A modification remains elusive. We here find TBK1, a key kinase of antiviral pathways, phosphorylates the core m6A methyltransferase METTL3 at serine 67. The phosphorylated METTL3 interacts with the translational complex, which is required for enhancing protein translation, thus facilitating antiviral responses. TBK1 also promotes METTL3 activation and m6A modification to stabilize IRF3 mRNA. Type I interferon (IFN) induction is severely impaired in METTL3-deficient cells. Mettl3fl/fl-lyz2-Cre mice are more susceptible to influenza A virus (IAV)-induced lethality than control mice. Consistently, Ythdf1-/- mice show higher mortality than wild-type mice due to decreased IRF3 expression and subsequently attenuated IFN production. Together, we demonstrate that innate signals activate METTL3 via TBK1, and METTL3-mediated m6A modification secures antiviral immunity by promoting mRNA stability and protein translation.

Abstract
Anterior and posterior approaches exist for the treatment of spinal pathologies. Anatomically, the 7th cervical spinal nerve(C7)crosses the C6-C7 intervertebral foramen bilaterally, allowing contralateral prevertebral or posterior C7 nerve transfer to be used. The advantage of the posterior rather than the anterior spinal approach is that it does not require retraction of important blood vessels, nerves, or other structures. In this paper, we describe transfer of the contralateral C7 nerve using a posterior approach.

Abstract
BACKGROUND TYK2 deficiency is a rare primary immunodeficiency disease caused by loss-of-function mutations of TYK2 gene, which is initially proposed as a subset of hyper-IgE syndrome (HIES). However, accumulating evidence suggests TYK2-deficient patients do not necessarily present with HIES characteristics, indicating a vacuum of knowledge on the exact roles of TYK2 in human immune system. METHOD Pathogenic effects of patients were confirmed by qRT-PCR, Western blot, and protein stability assays. The responses to cytokines including IFN-α/β/γ, IL-6, IL-10, IL-12, and IL-23 of peripheral blood mononuclear cells (PBMCs) from these patients were detected by Western blot, qRT-PCR, and flow cytometry. The differentiation of T and B cells was detected by flow cytometry. RESULTS We described five more TYK2-deficient cases presenting with or without hyper-IgE levels, atopy, and distinct pathogen infection profile, which are caused by novel TYK2 mutations. These mutations were all found by high-throughput sequencing and confirmed by Sanger sequencing. The patients showed heterogeneous responses to various cytokine treatments, including IFN-α/β/γ, IL-6, IL-10, IL-12, and IL-23. The homeostasis of lymphocytes is also disrupted. CONCLUSION Based on our findings, we propose that TYK2 works as a multi-tasker in orchestrating various cytokine signaling pathways, differentially combined defects which account for the expressed clinical manifestations.

Abstract
It is a case found during routine reexamination one year after implantable Collamer lens (ICL) implantation. The patient had no complaints. The naked eye visual acuity of the left eye was 1.0, and abnormal blood vessels were seen in the supranasal retina. After fluorescein fundus angiography and sweep source OCTA, it was finally diagnosed as retinoschisis with microvascular anomalies of the left eye. This case suggests that the fundus of patients with high myopia without complaint should also be examined in detail and comprehensively. In addition to paying attention to peripheral retinopathy, the posterior pole and middle peripheral retina should be carefully examined, especially the areas that cannot be covered by conventional OCT.(Chin J Ophthalmol, 2021, 57: 944-945).

Abstract
Objective: To analyze the differences of the concentrations of metals and metalloids in bronchoalveolar lavage fluid (BALF) of patients with pneumoconiosis, so as to provide reference for the etiological diagnosis of pneumoconiosis. Methods: From September 2019 to August 2020, 47 pneumoconiosis patients hospitalized in Chongqing Prevention and Treatment Center for Occupational Diseases and undergoing bronchoalveolar lavage were selected as the research objects using cluster sampling method. The general situation and occupational history of patients were investigated by questionnaire, The BALF of 47 pneumoconiosis patients was collected, and the concentrations of metals and metalloids in BALF were detected by inductively coupled plasma mass spectrometry (ICP-MS) , the differences among patients with different types of pneumoconiosis, different stages of silicosis and different occupational history were analyzed by one-way ANOVA. Results: The concentrations of 50 metals and metalloids in BALF were detected, and 21 of them were analyzed. Compared with different types of pneumoconiosis, the concentrations of Zn, Mn and Sn in BALF were statistically significant (F=9.959, 3.635, 9.488, P<0.05) . The concentrations of K, Mg, Fe, Zn, Cu and Ni in BALF were significantly different in different stages of silicosis (F=4.271, 4.334, 3.588, 5.120, 7.340, 3.905, P<0.05) . The concentrations of Zn and Sn in pneumoconiosis patients with different types of work and types of exposed dust were significantly different (P<0.05) . Conclusion: The detection of Zn, Mn, Sn, and other metals in BALF can provide reference basis for the etiological diagnosis of pneumoconiosis and provide a new idea for the diagnostic method of pneumoconiosis.

Abstract
RNA and protein are interconnected biomolecules that can influence each other's life cycles and functions through physical interactions. Abnormal RNA-protein interactions lead to cell dysfunctions and human diseases. Therefore, mapping networks of RNA-protein interactions is crucial for understanding cellular processes and pathogenesis of related diseases. Different practical protein-centric methods for studying RNA-protein interactions have been reported, but few robust RNA-centric methods exist. Here, we developed CRISPR-based RNA proximity proteomics (CBRPP), a new RNA-centric method to identify proteins associated with an endogenous RNA of interest in native cellular context without pre-editing of the target RNA, cross-linking or RNA-protein complexes manipulation in vitro. CBRPP is based on a fusion of dCas13 and proximity-based labelling (PBL) enzyme. dCas13 can deliver PBL enzyme to the target RNA with high specificity, while PBL enzyme labels the surrounding proteins of the target RNA, which are then identified by mass spectrometry.

Abstract
Phase modulators based upon the thermo-optic effect are used widely in silicon photonics for low speed applications such as switching and tuning. The dissipation of the heat produced to drive the device to the surrounding silicon is a concern as it can dictate how compact and tightly packed components can be without concerns over thermal crosstalk. In this paper we study through modelling and experiment, on various silicon on insulator photonic platforms, how close waveguides can be placed together without significant thermal crosstalk from adjacent devices.

Abstract
Abstract
Background
Several electrocardiographic (ECG) indices have previously been proposed to diagnose left ventricular hypertrophy (LVH). Such indices utilize different criteria, including increased QRS voltage, prolonged QRS duration, left axis deviation, and LAFB and LBBB-like patterns in varying combinations. However, the inter-relationships of these different electrocardiographic indices of LVH with each otherare not fully understood.
The purpose of this study is to estimate the relationships between the different LVH indices.
Methods
Electronic tracings of 12-lead ECGs recorded in 24,786 adult participants in the China Kadoorie Biobank recorded in 2014 were accessed to detect presence of LVH. ECG parameters of LVH, including individual and combinations of such parameters (voltage-only criteria such as Sokolov-Lyon, Cornell, Gubner as well as scores such as Romhilt-Estes point score) were estimated using customized computer software (Cardiolyse Oy, Finland) and compared proprietary LVH point score algorithms (Mortara, USA). Relationships between the different indices were assessed using a correlation matrix to explore associations between individual parameters and combined indices of such parameters. The matrices were used to construct heat maps and identify clustering of individual parameters.
Results
Overall, approximately 10% of the population had LVH assessed by Mortara algorithms. This graph shows that along with the free standing peaks, the rest are divided into two clusters of interconnected individual parameters. In the center of the largest cluster is the parameter, reflecting R-peak magnitude in aVL lead. In the center of another cluster was the left ventricular strain pattern, as described in Romhilt-Estes point score system. Overall, the Sokolov-Lyon index and LVH point score in Veritas algorithm had the strongest relationships with each other, but the Gubner and Cornell indices had relatively weak correlations with the other indices (Table 1). The mean correlation coefficient between five combined LVH indices was as follows: Veritas (Mortara) – 0.58, Sokolov-Lyon – 0.56, Romhilt-Estes – 0.45, Gubner – 0,32, Cornell – 0,3.
Conclusions
Parameters such as R-peak magnitude in aVL and left ventricular strain pattern were the most strongly related with each other. Aggregate indices, such as the Sokolov-Lyon index and LVH point score in Veritas algorithm were the most strongly related with all other indices, but the Gubner and Cornell indices were only weakly correlated. The results reinforce the utility of Sokolov-Lyon index and Mortara algorithms as the optimum measures of LVH.

Abstract
Abstract
Background
Evidence on the association between dairy consumption and risk of cardiovascular disease has been highly inconsistent, with findings suggesting either harmful, neutral or beneficial effects. In addition, a very large majority of the previous studies on this topic were conducted among populations in Europe and North America who usually consume a higher amount of dairy products and very few data, particularly prospective data, come from China where the dairy consumption level is low.
Purpose
We therefore investigated the associations between intake of dairy products and incidence of several major types of cardiovascular diseases in Chinese adults.
Methods
During 2004–2008, the prospective China Kadoorie Biobank Study recruited slightly over 0.5 million adults from ten diverse regions (five urban and five rural) across China. Information on the consumption frequency of dairy products was collected at baseline and periodic resurveys, using a validated interviewer-administered laptop-based questionnaire. Over a mean follow-up of 10.9 years, there were 47,128 incident ischaemic heart disease events, 43,481 ischaemic strokes and 9749 intracerebral haemorrhages among 489,595 study participants, who did not report a prior history of cardiovascular disease at baseline. Cox regression analyses were performed to estimate multivariable-adjusted hazard ratios (HRs) for incident events associated with dairy intake.
Results
Overall, 69.3% of participants reported never or rare consumption (i.e. non-consumers) and 11.3% of them reported regular consumption (i.e. ≥4 days/week) of dairy products, with milk accounting for the largest proportion of total dairy intake (∼77%). Male and female regular dairy consumers had 2.1/1.5 and 1.7/1.1 mmHg lower systolic/diastolic blood pressure, respectively compared to non-consumers. In a subset (∼18,000) of participants with blood lipid levels measured, regular dairy consumers had ∼0.1 mmol/L higher LDL levels than non-consumers. After adjusting for a range of potential confounders, including sociodemographic and lifestyle factors, BMI and other dietary factors, dairy consumption was positively and significantly associated with risk of ischaemic heart disease, with the adjusted HR per 50 g/day increase in usual dairy consumption being 1.11 (95% confidence interval [CI] 1.09–1.14). Dairy consumption was not significantly associated with risk of ischemic stroke but was inversely associated with risk of intracerebral haemorrhage, with each 50 g/day increase in usual dairy consumption being associated with 17% lower risk (HR 0.83, 0.78–0.88). These associations remained significant after additional adjustment for systolic blood pressure.
Conclusion
In this large study of Chinese adults, higher intake of dairy products was associated with a higher risk of ischaemic heart disease but a lower risk of intracerebral haemorrhage. The exact mechanisms underlying such associations require further investigation.

Abstract
Abstract
Background
Higher red meat intake and lower fish intake have been associated with increased risk of cardiovascular disease (CVD), while the relevance of poultry and egg intake for CVD incidence remains inconclusive. Furthermore, most of the prospective evidence comes from studies in the Western populations, with limited data from China where the CVD patterns are largely different.
Purpose
We therefore investigated the associations of red meat, poultry, fish and egg intake with risks of several major types of CVD in Chinese adults.
Methods
The China Kadoorie Biobank is a prospective study which recruited ∼512,000 adult participants from ten diverse localities during 2004–08. At baseline and periodic resurveys, information on the consumption frequency of major food groups was collected using a validated interviewer-administered laptop-based questionnaire, together with medical history, socio-demographic and other lifestyle factors. During an average follow-up of 10.9 years, 47,128 incident ischaemic heart disease events, 43,481 ischaemic strokes and 9749 intracerebral haemorrhages were recorded among 489,595 participants, who did not have a prior history of CVD at baseline. Cox regression was used to calculate adjusted hazard ratios (HRs) relating dietary exposures to CVD risk.
Results
There were 47.2%, 1.4%, 9.0% and 24.1% of participants at baseline who regularly consumed (i.e. ≥4 days/week) red meat, poultry, fish and eggs, respectively. After adjusting for potential confounders, including body mass index and other dietary factors under study, egg consumption was significantly associated with lower risks of ischaemic heart disease and ischaemic stroke, with each 50 g/day increase in estimated habitual egg consumption being associated with 18% (HR 0.82, 95% confidence interval [CI] 0.75–0.90) and 24% lower risks (HR 0.76, 95% CI 0.69–0.84), respectively. Inverse associations were also observed between intakes of red meat, fish and eggs and risk of intracerebral haemorrhage, with adjusted HRs for 50 g/day higher intake being 0.84 (95% CI 0.74–0.97), 0.86 (95% CI 0.74–0.99) and 0.42 (95% CI 0.34–0.51), respectively.
Conclusion
This large prospective study of Chinese adults showed that higher intake of eggs was associated with lower risks of ischaemic heart disease and ischaemic stroke. Moreover, higher intakes of red meat, fish and eggs were each associated with a lower risk of intracerebral haemorrhage. Further investigation of the potential mechanisms that underlie the observed associations is required.

Abstract
We investigate the magnetic properties of a chemically heterogeneous binary-main-phase (BMP) Nd-Ce-Fe-B magnet with a core-shell structure via micromagnetic simulation. It is found that the coercivity strongly depends on the shell thickness. The BMP magnet's coercivity initially increases and then decreases with increasing Nd-rich shell thickness, and so there is the optimal shell thickness which shows the maximum coercivity for any given Ce concentration. The simulation shows the significant difference in coercivity and maximum energy product between the BMP and single-main-phase magnets. Notably, the magnetization reversal mechanism of the BMP magnet is revealed in the simulation. Local reversals in the BMP magnet first occur in the Ce-rich shells, followed by the Nd-rich cores. Then, the magnetization in Ce-rich core/Nd-rich shell typed grains is switched after reversed magnetization of all the Nd-rich core/Ce-rich shell typed grains. The BMP magnet represents a further increased coercivity for a larger GB thickness, which can be well explained by a maximum stray field.

Abstract
Evaluate the effect of the fresh air purification system on the improvement of indoor PM2.5 levels in a primary school classroom in Jinan City, Shandong Province. Our purpose is to explore the optimal operating time of the fresh air system and the main factors that affect the fresh air purification system to improve indoor air quality. From December 9, 2019 to December 10, 2019, two classrooms of the same area on the third floor of a primary school building in Jinan City, Shandong Province were selected as monitoring points. During the operation of the fresh air purification system, the PM2.5 concentration in the classroom is reduced by an average of 48.1%-61.5% compared to the outdoor PM2.5 concentration. After running for about 2 hours, the indoor PM2.5 concentration decreased to a relatively stable concentration level. The operating time of the fresh air purification system, student activities between classes, indoor temperature, indoor relative humidity, and outdoor PM2.5 concentration are important factors that affect the indoor particulate removal rate. In the case of a certain amount of fresh air and indoor area, closing doors and windows and appropriately extending the operation time of the fresh air purification system can improve the air quality in the classroom to a certain extent and protect the health of students.

Background/significance. Cardiac rehabilitation (CR) significantly reduces death, reoccurring cardiac events, hospital admissions while improving quality of life. However, it is still poorly attended with participation rates worldwide between 20-50%, worsened for rural and remote patients by the tyranny of distance, work responsibilities and transportation. Web-based CR can provide an alternative, patient centred, flexible delivery option. Co-design with consumers and clinicians is recommended to tailor web-based CR to their needs and preferences as a means of increasing attendance.
Purpose. The objective of this study is to describe how patient-generated data through workshops on desired content and features informs technology and implementation specifications for the patient portal of a CR website.
Methods. UX Design theoretical framework, using a co-design workshop, with thematic analysis, a survey, and the System Usability Scale was used to report outcomes.
Results. Based on the feedback from participants in rural and remote SA, desired content and features were updated for improving user experience. We recruited 27 participants across 4 regional Local health Networks in SA. The median age of participants was 71.0 (IQR 58-78), 14 (51.9%) were female and 27 (100%) had completed a cardiac rehabilitation program. More than half used a smart phone (16; 59.3%) and Facebook (21; 77.8%). Overall usability remains low based on a mean SUS score of 63.4 (SD 21.1), however there was a tendency to usability improving over time.
Conclusion. The co-design process has contributed to the development of the CR website, improving desired content and features. Improved usability scores can be achieved through further incorporating consumer feedback into the development of the CR website.

Abstract
PURPOSE The safety of mirabegron 50mg monotherapy was comprehensively assessed versus placebo for overactive bladder. METHODS A systematic literature search was conducted up to June, 2020 using PUBMED, EMBASE and Cochrane Library. Randomized controlled trials evaluating safety of mirabegron in overactive bladder were collected, and safety was assessed according to 15 adverse events. Adverse events were widely selected to be assessed if they could be calculated. Heterogeneity among studies was assessed by using the χ2 test based on the Q and I2 tests. Pooled effect sizes were calculated using fixed model if I2<50%, otherwise a random-effects model was chosen. The outcomes were nasopharyngitis, dry mouth, hypertension, constipation, headache, dyspepsia, urinary tract infection, dizziness, blurred vision, nausea, cardiovascular events, influenza, electrocardiogram QT prolonged, upper respiratory tract infection and high blood pressure. RESULTS In all, 10 peer-reviewed trials comprising 6135 patients were identified. Compared with placebo, mirabegron 50mg had an unfavorable safety profile resulting in nasopharyngitis (OR, 1.54[95% credible interval, 1.05-2.25]; P=0.03. No statistical difference was found between mirabegron 50mg and placebo groups in other 14 outcomes. CONCLUSION Mirabegron 50mg is further confirmed to be nearly as safe as placebo, expect for nasopharyngitis. Nasopharyngitis is associated with mirabegron 50mg monotherapy for patients with overactive bladder.

Abstract
Objective: To understand the epidemiological and genotypic characteristics of imported cases of measles virus of D8 genotype in Hebei province. Methods: Epidemiological investigation of measles cases in surveillance was carried out. The throat swabs of the measles cases in acute phase were collected for real time RT-PCR identification, measles virus culture and genotype identification. Results: A total of 36 imported measles cases of genotype D8 were detected. The cases were mainly distributed in 8 counties of Handan city. Number of confirmed measles cases in Cheng'an county was the highest, accounting for 58.33% (21/36) of all the reported cases. All patients had fever and rash, and 55.55% (20/36) of the cases were under 2 years old and 86.11% (31/36) of the cases had no immunization history. The children with pneumonia accounted for 44.12% (15/34) of the total children with D8 genotype measles virus infection. The nucleotide and amino acid homologies between the imported measles virus genotype D8 and the WHO reference strain of D8 genotype (D8-Manchester.UNK/30.94) were 98.4%-98.6% and 97.3%, respectively. Compared with the strains of H1 genotype in China, the nucleotide and amino acid homologies were 92.8%-93.1% and 93.3%, respectively. Conclusions: The imported cases of measles virus of D8 genotype might have caused local transmission in Hebei province. Molecular epidemiological surveillance for measles virus needs to be further strengthened. It is necessary to detect and control the epidemic early and improve the coverage rate and timely rate of measles vaccination. It is also important to prevent cross infection in hospitals.

Abstract
OBJECTIVE Experimental autoimmune myocarditis (EAM) is characterized by pronounced macrophage infiltration, cardiac necrosis, and cardiac fibrosis. Our previous studies have demonstrated that suppressed androgen receptor (AR) enables anti-inflammation to promote tissue repair by decreasing M1 macrophages and increasing M2 macrophages in an EAM model. Given that autophagy mediates inflammatory response in macrophages, we investigated whether AR inhibition executes its protective role in inflammation through the autophagy pathway in EAM. MATERIALS AND METHODS To determine whether AR inhibition can perform its anti-inflammatory effects by upregulating autophagy, we pre-treated mice with 3-methyl adenine (3-MA), a pharmacological inhibitor of autophagy. Immunofluorescence assay and Western blot were used to detect autophagy levels and autophagy activity in five different groups. Immunofluorescence marked F4/80 and LC3 to illustrate the autophagy level in macrophages. TUNEL assays were used to detect the apoptosis level in heart tissue of five different groups. RESULTS We demonstrated that AR inhibition resolves injury with sustained inhibition of inflammatory cytokines associated with enhanced autophagy, especially in macrophages. Increased LC3II/I expression corroborated complete autolysosome formation detected by electron microscopy and correlated with degradation of SQSTM1/p62 in the AR inhibition group by Western blot. These effects could be reversed within 3-MA, a pharmacological inhibitor of autophagy. Specifically, pharmacological inhibition of autophagy increased apoptosis and inflammation, which could be attenuated by AR inhibition. CONCLUSIONS AR inhibition alleviates the inflammatory response and tissue apoptosis by enhancing autophagy, especially in macrophages.

Abstract
Objective: To evaluate the efficacy of high-risk HPV (HR-HPV) genotyping with vaginal self-sampling in primary screening and combining cytology or viral load for HR-HPV positive as secondary screening strategies. Methods: The data referring to HR-HPV genotyping of self-collected sample with mass array matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF-MS), HR-HPV viral load of physician-collected sample with hybrid capture Ⅱ (HC-Ⅱ), liquid-based cytology and histology of 8 556 women were from Shenzhen cervical cancer screening trial Ⅱ (SHENCCAST-Ⅱ) conducted between April 2009 and April 2010. The data were reanalyzed to determine the sensitivity and specificity to cervical intraepithelial neoplasia (CIN) of grade 2 or worse (CIN Ⅱ+), CIN of grade 3 or worse (CIN Ⅲ+) when HR-HPV genotyping combining with colposcopy as primary screening strategy based on varied HR-HPV subtype (strategy 1, including 5 sub-strategies: 1a: HPV 16/18 positive; 1b: HPV 16/18/58 positive; 1c: HPV 16/18/58/31/33 positive; 1d: HPV 16/18/58/31/33/52 positive; 1e: any HR-HPV positive). The data were also compared to determine the efficacy of cytology (strategy 2, including 5 sub-strategies: 2a, 2b, 2c, 2d, 2e) or HR-HPV viral load (strategy 3, including 4 sub-strategies: 3a, 3b, 3c, 3d) of physician-collected sample as a triage with HR-HPV genotyping for self-sampling HR-HPV positives. Results: (1) The HR-HPV positive rate was 13.77% (1 178/8 556) in the self-collected samples of 8 556 pregnant women. Of them,the prevalences of HPV 16/18, HPV 16/18/58, HPV 16/18/58/31/33 and HPV 16/18/58/31/33/52 were 3.16% (270/8 556), 5.14% (440/8 556), 6.66% (570/8 556) and 9.81% (839/8 556), respectively. The HR-HPV viral load ≥10 relative light units/control (RLU/CO) was 8.87%(759/ 8 556), while cytological results ≥atypical squamous cell of undetermined signification (ASCUS) were 12.05% (1 031/8 556). (2) The strategy 1e had the highest sensitivities for CIN Ⅱ+, CIN Ⅲ+ which were 92.70% and 94.33%,respectively,among 14 sub-strategies,while the lowest specificity and positive predictive value (PPV). Meanwhile,the required colposcopy referral rates were much higher than other 13 sub-strategies (13.77%). The other 4 sub-strategies of strategy 1 (1a, 1b, 1c, 1d), strategy 1a had the highest specificities for CIN Ⅱ+ and CIN Ⅲ+ (97.92%, 97.69%, respectively), while 1d had the highest sensitivities for CIN Ⅱ+ and CIN Ⅲ+ (88.41%, 92.20%, respectively). (3) Both strategies of referring self-sampling HPV 16/18 positives for immediate colposcopy followed by triage physician-collected sample cytology (≥ASCUS) or viral load (≥10 RLU/CO) for non-HPV 16/18 positives had significantly higher sensitivity and specificity for CIN Ⅱ, CIN Ⅲ+, as well as lower referral rates (strategy 2a and 3a). Additionally, based on these two secondary screening strategies, cumulatively using the other four HR-HPV (HPV 58, 31, 33 and 52) positives as triage for immediate colposcopy showed an enhanced sensitivity. Conclusions: Primary HR-HPV cervical cancer screening strategy based on self-sampling with triage of cytology (≥ASCUS) or viral load (≥10 RUL/CO) provides a good balance among sensitivity, specificity for CIN Ⅱ+ and CIN Ⅲ+ and the number of tests required, referral rates. The efficacy of HR-HPV genotyping combining cytology or viral load secondary screening strategies will have a spiral escalation when HPV 58, 31, 33, 52 are included.

Abstract
RNA and protein are interconnected biomolecules that can influence each other's life cycles and functions through physical interactions. Abnormal RNA-protein interactions lead to cell dysfunctions and human diseases. Therefore, mapping networks of RNA-protein interactions is crucial for understanding cellular processes and pathogenesis of related diseases. Different practical protein-centric methods for studying RNA-protein interactions have been reported, but few robust RNA-centric methods exist. Here, we developed CRISPR-based RNA proximity proteomics (CBRPP), a new RNA-centric method to identify proteins associated with an endogenous RNA of interest in native cellular context without pre-editing of the target RNA, cross-linking or RNA-protein complexes manipulation in vitro. CBRPP is based on a fusion of dCas13 and proximity-based labelling (PBL) enzyme. dCas13 can deliver PBL enzyme to the target RNA with high specificity, while PBL enzyme labels the surrounding proteins of the target RNA, which are then identified by mass spectrometry.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease, characterized by relapsing and remitting colon mucosal inflammation. For patients suffering from UC, a higher risk of colon cancer has been widely recognized. Here, we found that Elf4−/− mice developed colon tumors with 3 cycles of dextran sulfate sodium salt (DSS) treatment alone. We further showed that ELF4 suppression was prevalent in both patients with UC and DSS-induced mice models, and this suppression was caused by promoter region methylation. ELF4, upon PARylation by PARP1, transcriptionally regulated multiple DNA damage repair machinery components. Consistently, ELF4 deficiency leads to more severe DNA damage both in vitro and in vivo. Oral administration of montmorillonite powder can prevent the reduction of ELF4 in DSS-induced colitis models and lower the risk of colon tumor development during azoxymethane (AOM) and DSS induced colitis-associated cancer (CAC). These data provided additional mechanism of CAC initiation and supported the “epigenetic priming model of tumor initiation”. Elf4 expression is suppressed in both colitis and colitis-associated cancer (CAC). Elf4 deficiency leads to increased hyper-susceptibility to colitis and CAC in mice Elf4 promotes DNA damage repair upon PARylation by PARP1 Oral administration of montmorillonite lowers risk of CAC development

Abstract
Mitochondria not only serve as a platform for innate immune signaling transduction but also enhance immune responses by releasing mitochondrial DNA and RNA into the cytoplasm. However, whether mitochondrial matrix proteins could be liberated and involved in immune responses remains enigmatic. Here, we identify the mitochondrial protein ERA G-protein-like 1 (ERAL1) as a mitochondrial antiviral signaling protein (MAVS)-interacting protein by using proximity-based labeling technology. ERAL1 deficiency markedly reduces the downstream antiviral signaling triggered by RNA viruses. Moreover, ERAL1-deficient mice are more susceptible to lethality following RNA virus infection than wild-type mice. After virus infection, ERAL1 is released from mitochondria through the BAX/BAK pore. The cytosolic ERAL1 facilitates lysine 63 (K63)-linked ubiquitination of retinoicacid inducible gene-1 (RIG-I)/melanoma differentiation-associated gene 5 (MDA5) and promotes downstream MAVS polymerization, thus positively regulating antiviral responses.

Exclusion criteria include animal experiments; repeated reports; review articles; research exposure factors do not include PM2.5; children self-harm and illegal behaviors. Finally, 25 articles were included. Results: Among the 25 included articles, 12 studies discussed the relationship between PM2.5 exposure and childhood behavioral disorders, 13 discussed the relationship between PM2.5 exposure and abnormal behaviors in children, and 5 studies based on the Chinese population. According to the research design, it is divided into birth cohort studies (15), cross-sectional studies (5), and case-control studies (5). China mainly uses cross-sectional studies and case-control studies. The results of the study suggest that PM2.5 exposure will increase the risk of children's behavioral problems, with both short-term and long-term effects. Short-term exposure to PM2.5 can easily cause mild abnormal behaviors in children, and long-term exposure may increase the risk of children's behavioral disorders. The fetal period and the infant period may be the key exposure window for the occurrence of children's behavior problems. Conclusion: There may be a certain correlation between PM2.5 exposure and children's behavioral problems. In future studies, longitudinal cohort studies should be carried out to enhance the causal relationship between fine particulate matter pollution and children's behavioral problems.

Abstract
OBJECTIVE To explore the correlation of the growth differentiation factor-15 (GDF-15) with the severity of chronic heart failure (CHF) in patients with coronary atherosclerosis. PATIENTS AND METHODS 300 coronary atherosclerosis patients with CHF treated in our hospital from January 2019 to December 2019 and 300 healthy people (control group) were collected and retrospectively analyzed. The basic clinical information of the patients, such as age, gender, smoking/drinking history, waist-hip ratio, BMI and blood lipid were collected, and GDF-15, cystatin C and c-reactive protein (CRP) were determined. The severity of heart failure was classified. RESULTS No significant differences in clinical information were found such as age, gender, smoking/drinking history, waist-to-hip ratio, BMI and blood lipid. However, there were significant differences in GDF-15, cystatin C and CRP among patients with different severities of heart failure. The GDF-15 level was 582.6 ± 104.4 pg/ml in patients with grade IV heart failure and 408.4 ± 94.8 pg/ml in patients with grade I heart failure. There was a significance after GDF-15, cystatin C and CRP were adjusted (p = 0.03) and also after the clinical information and GDF-15 were adjusted (p < 0.001). CONCLUSIONS GDF-15 level is correlated with the CHF severity in patients with coronary atherosclerosis, indicating that it is a potential index to evaluate the CHF severity, providing clues to the biological mechanism and treatment of heart failure.

Abstract
Objective: Evaluation of the clinical value of the BioPerfectus multiplex real time (BMRT)-HPV for cervical cancer screening. Methods: Physician-collected specimens of 1 495 women who were positive of Cobas 4800 HPV (Cobas-HPV), HPV genotyping based on SEQ uencing (SEQ-HPV), and (or) cytology ≥low grade squamous intraepithelial lesion (LSIL) in the primary screening of Chinese Multiple-center Screening Trial (CHIMUST), and 2 990 women selected from those who were negative of primary screening in the same project through nested control randomization with age-matching were tested for BMRT-HPV, which reported type-specific viral loads/10 000 cells in each specimen. With comparing to Cobas-HPV results and taking cervical histopathological diagnosis as the endpoint, the concordance of high-risk (HR)-HPV subtypes among the three assays was explored ,and the sensitivity and specificity of BMRT-HPV for cervical cancer screening were evaluated. Results: (1) The overall agreenment of HR-HPV subtypes between BMRT-HPV and Cobas-HPV, or SEQ-HPV test sample was 94.8%, 94.4%, with Kappa values 0.827, 0.814. (2) The sensitivity and specificity for cervical intraepithelial neoplasia (CIN) Ⅱ+ of BMRT-HPV, Cobas-HPV and SEQ-HPV were 92.62%, 94.26%, 93.44% and 84.67%, 83.25%, 82.76%, respectively. There were no significant difference in sensitivity among the three HPV assays (all P>0.05), but the specificity of BMRT-HPV for CIN Ⅱ+ was higher than those of Cobas-HPV and SEQ-HPV (P<0.01). The sensitivity for CIN Ⅲ+ of three HPV assays were all 100.00%, and the specificity for CIN Ⅲ+ of BMRT-HPV was higher than those of Cobas-HPV and SEQ-HPV (83.40% vs 81.95%, 83.40% vs 81.50%; P<0.01). The number of pathological examinations of colposcopy for cervical biopsy detected in 1 case of CIN Ⅱ+ or CIN Ⅲ+ in BMRT-HPV was less than those in Cobas-HPV and SEQ-HPV (P<0.01). When using HPV 16/18 + cytology ≥atypical squamous cell of undetermined signification (ASCUS) to triage HPV positive women among three assays, there was no different in the sensitivities of detecting CIN Ⅱ+ and CIN Ⅲ+ (P>0.05). The specificity BMRT-HPV was slightly higher than those in Cobas-HPV or SEQ-HPV (all P<0.05), and the colposcopy referral rate was lower than those in Cobas-HPV and SEQ-HPV (all P<0.05). Conclusions: BMRT-HPV is as sensitive as Cobas-HPV or SEQ-HPV for primary cervical cancer screening, and has higher specificity. Therefore it could be used as a primary screening method for cervical cancer, which is worthy of clinical application.

Abstract
Abstract
Background
The prevalence of left ventricular hypertrophy (LVH) is strongly related with established cardiovascular disease (CVD) risk factors and, hence, there has been some uncertainty about its independent relevance for ischaemic heart disease (IHD) after taking account of such risk factors.
Purpose
To examine the associations of LVH with prevalent and incident cases of IHD after adjustment for established risk factors for CVD in a population-based study of Chinese adults.
Methods
The prospective China Kadoorie Biobank cohort study was conducted in the general population of 5 urban and 5 rural areas in China, with a baseline survey in 2004–2008. A random sample of 24,786 participants had a 12-lead electrocardiogram (ECG) recorded at the second resurvey in 2013–2014. Electronic records of ECG tracings were used to estimate LVH using 5 different criteria (Sokolov, Cornell, Romhilt-Estes, Gubner and Mortara). IHD cases were recorded by linkage to electronic records of hospitalisation, death and disease registries. Cox regression was used to estimate the associations of LVH with prevalent (n=1325) and incident (n=900) cases of IHD after adjustment for age, sex, region, prior vascular disease, smoking, alcohol, SBP, diabetes, lipids and body mass index (BMI).
Results
The overall prevalence of LVH in the population varied depending on the criteria used for detection (Mortara [10%], Sokolov [14%], Cornell [6%], Romhilt-Estes [4%] and Gubner [1%]). The prevalence of LVH (using Sokolov) increased with age and was higher in men than women (20% vs 10%) and linearly with levels of SBP, but also by ∼10-fold between the 10 regions in China. Irrespective of which criteria were used for detection (Table), LVH was strongly associated with both prevalent and incident cases of IHD after adjustment for age, sex, region and established CVD risk factors. Any one measure of LVH was associated with an adjusted OR (95% CI) of 1.30 (1.10, 1.53) for prevalent IHD and 1.40 (1.20, 1.64) for incident IHD, respectively.
Conclusions
Overall, 1 in 10 Chinese adults had LVH, and LVH was associated with 30% higher risk of prevalent IHD and 40% higher risk of IHD independent of established CVD risk factors.
