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
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
Folate receptor 1 (FOLR1) is overexpressed in numerous epithelial malignancies; however, its role in laryngeal squamous cell carcinoma (LSCC) remains unclear. In the present study, we demonstrated that FOLR1 messenger RNA and protein expression levels were higher in LSCC tissues than in the adjacent normal tissues. Additionally, FOLR1 promoted the proliferation and migration of LSCC cells, whereas small interfering RNA-mediated knockdown of β-catenin abolished these effects. Moreover, FOLR1 stabilizes β-catenin by inhibiting its ubiquitination and degradation. Furthermore, blocking the interaction between epidermal growth factor receptor (EGFR) and the EGFR/AKT/glycogen synthase (GSK)3β signaling axis both abolished FOLR1's effects on the expression and nuclear aggregation of β-catenin. In summary, our work reveals a novel mode in which FOLR1 promotes the proliferation and migration of LSCC by enhancing the stability and nuclear translocation of β-catenin through the EGFR/AKT/GSK3β axis.

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
Yinhuapinggan granule (YHPG) is a traditional Chinese medicine prescription with rich clinical experience for the treatment of colds and coughs. The aim of this study is to investigate the protective effect of YHPG on multidrug-resistant (MDR) Acinetobacter baumannii (A. baumannii) infection in vivo and its potential anti-inflammatory mechanism. BALB/c mice were intranasally inoculated with MDR A. baumannii strain to establish the pneumonia infection model, and received intraperitoneally cyclophosphamide to form immunosuppression before attack. YHPG (6, 12 and 18 g/kg) was administered by gavage once a day for 3 consecutive days after infection. The protective effect of YHPG was evaluated by lung index, spleen index, thymus index, pathological changes of lung tissue and inflammatory factors (IL-1β, IL-6 and TNF-α) in serum. The expression of key targets of NF-κB/NLRP3 signaling pathway in vivo was analyzed by immunohistochemistry, immunofluorescence, reverse transcription quantitative PCR (RT-qPCR) and Western blot. The results showed that YHPG improved the lung index and its inhibition rate, immune organ indexes and lung pathological changes in infected mice, and significantly reduced IL-1β, IL-6 and TNF-α levels in serum. In addition, YHPG significantly down-regulated the mRNA and protein expression of NF-κB p65, NLRP3, ASC, Caspase-1, TNF-α, IL-6 and IL-1β in mice lung tissue. The results of the current study demonstrated that YHPG has significant protective effects on mice infected with MDR A.baumannii, which may be related to the regulation of inflammatory factors and NF-κB/NLRP3 signaling pathway, indicating that YHPG has a wide range of clinical application value and provides a theoretical basis for its treatment of MDR A.baumannii infection.

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
Objectives To explore the relationship between depressive symptoms, fatigue and psychological flexibility, as well as their interactions on depression in Chinese nurses. Material and Methods Using convenience sampling, a cross-sectional survey of 796 nurses in municipal hospitals of Zhengzhou, Henan Province, China, was conducted. The questionnaires of Work-related Acceptance and Action Questionnaire, Center for Epidemiological Studies Depression Scale and Fatigue Assessment Instrument were used. Hierarchical regression and bootstrap methods were used to examine the mediating effect of psychological flexibility between fatigue and depression. Results More than 51.8% of the nurses were at risk of depression and 62.3% were at risk of fatigue. There was a significantly positive and moderate correlation between depression and fatigue severity, situation specificity, and consequences (r = 0.43, r = 0.24 and r = 0.31, respectively, p < 0.01). Depression was negatively correlated with psychological flexibility (r = -0.28, p < 0.01). Psychological flexibility had a negative impact on depression with the explained variance increased by 4.2% (β = -0.211, p < 0.001). The bootstrap method showed that the mediating effect of psychological flexibility accounting for 8.5% and 12.3% on fatigue and depressive symptoms, respectively. Conclusions Psychological flexibility plays a partial mediating role between the fatigue severity, consequences of fatigue and depressive symptoms of nurses. Hospital managers should improve medical staff work acceptance to alleviate their depressive symptoms. Int J Occup Med Environ Health. 2023;36(4):563-74.

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
BACKGROUND As a common cerebrovascular disease (CVD) of the elderly, ischemic stroke (IS) is characterized by high disability and mortality. Excessive autophagy induced by IS is implicated in neuronal death, therefore, the inhibition of immoderate autophagy is viewed as a potential therapeutic avenue to treat IS. Calysoin (CA) is a bioactive component of Radix Astragali, which has been widely used to treat CVDs. However, the mechanism of the treatment of IS by CA is still problematic. PURPOSE Based on the result of network pharmacology, whether CA inhibited autophagy by regulating the STAT3/FOXO3a pathway to alleviate cerebral ischemia-reperfusion injury (CIRI) was investigated in vivo and in vitro for the first time. STUDY DESIGN Integrate computational prediction and experimental validation based on network pharmacology. METHODS In current study, network pharmacology was applied to predict the mechanism of the treatment of IS by CA, and it was shown that CA alleviated CIRI by inhibiting autophagy via STAT3/FOXO3a signaling pathway. One hundred and twenty adult male specific pathogen-free Sprague-Dawley rats in vivo and PC12 cells in vitro were used to verify the above prediction results. The rat middle cerebral artery occlusion/reperfusion (MCAO/R) model was established by suture method, and oxygen glucose deprivation/re-oxygenation (OGD/R) model was used to simulate cerebral ischemia in vivo. The content of MDA, TNF-α, ROS and TGF-β1 in rat serum were detected by ELISA kits. The mRNA and protein expressions in brain tissue were detected by RT-PCR and Western Blotting. The expressions of LC3 in brain were detected immunofluorescent staining. RESULTS The experimental results demonstrated that administration of CA dosage-dependently improved rat CIRI as evidenced by the reduction in the cerebral infarct volume, amelioration of the neurological deficits. HE staining and transmission electron microscopy results revealed that CA ameliorated cerebral histopathological damage, abnormal mitochondrial morphology, and damaged mitochondrial cristae structure in MCAO/R rats. CA treatment exerted protective effects in CIRI by inhibiting inflammation response, oxidative stress injury, and cell apoptosis in rat and PC12 cells. CA relieved excessive autophagy induced by MCAO/R or OGD/R through downregulating the LC3Ⅱ/LC3Ⅰ ratio and upregulating the SQSTM1 expression. CA treatment also decreased p-STAT3/STAT3 and p-FOXO3a/FOXO3a ratio in the cytoplasm and modulated the autophagy-related gene expression both in vivo and in vitro. CONCLUSION Treatment with CA attenuated CIRI by reducing excessive autophagy via STAT3/FOXO3a signal pathway in rat and PC12 cells.

Abstract
Skeletal muscle atrophy is often found in patients with type 2 diabetes mellitus (T2DM), which is characterized by insulin resistance. As the largest tissue in the body, skeletal muscle plays important roles in insulin resistance. Advanced glycation end products (AGEs) are a type of toxic metabolite that are representative of multiple pathophysiological changes associated with T2DM. Mice were exposed to AGEs. Forkhead box O1 (FOXO1) was silenced by using a constructed viral vector carrying siRNA. Skeletal muscle atrophy was evaluated by using hematoxylin-eosin (H&E), oil red O, myosin skeletal heavy chain (MHC), and laminin immunofluorescent stains. Reactive oxygen species (ROS) generation was assessed by using the dihydroethidium (DHE) stain. Western blotting was used to evaluate protein expression and phosphorylation. Insulin resistance was monitored via the insulin tolerance test and the glucose infusion rate (GIR). Mice exposed to AGEs showed insulin resistance, which was evidenced by reduced insulin tolerance and GIR. H&E and MHC immunofluorescent stains suggested reduced cross-sectional muscle fiber area. Laminin immunofluorescent and oil red O stains indicated increased intramuscular fibrosis and lipid deposits, respectively. Exposure to AGEs induced ROS generation, increased phosphorylation of protein kinase RNA-like endoplasmic reticulum kinase (PERK) and FOXO1, facilitated FOXO1 nuclear translocation, and elevated expression of muscle atrophy F-box (MAFbx) in gastrocnemius muscle. foxo1 silencing significantly suppressed skeletal muscle atrophy and insulin resistance without affecting ROS production. AGEs exacerbated skeletal muscle atrophy and insulin resistance by activating the PERK/FOXO1 signaling pathway in skeletal muscle.NEW & NOTEWORTHY In this study, we proposed a molecular mechanism underlying the skeletal muscle atrophy-associated insulin resistance in type 2 diabetes mellitus (T2DM). Our investigation suggests that exposure to AGEs, which are characteristic metabolites of T2DM pathology, induces the activation of reactive oxygen species (ROS)-mediated endoplasmic reticulum (ER) stress, leading to the upregulation of the protein kinase RNA-like ER kinase (PERK)/forkhead box O1 (FOXO1)/muscle atrophy F-box pathway and subsequent skeletal muscle atrophy, ultimately resulting in insulin resistance.

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
Background: In view of the high morbidity and mortality of Diabetes mellitus-Coronary heart disease (DM-CHD) in diabetics, the combination therapy of traditional Chinese medicine injections (TCMIs) and conventional therapy (CT) is receiving extensive attention. Therefore, the effectiveness and security of conventional therapy with traditional Chinese medicine injections in the therapy of diabetes mellitus-coronary heart disease were compared by systematical review and network meta-analysis. Methods: According to the preset inclusion criteria and exclusion criteria, we searched seven electronic literature databases from their inception to JAN 5,2022, to obtain the relevant RCT literature on the therapy of diabetes mellitus-coronary heart disease with traditional Chinese medicine injections. Two researchers independently reviewed the papers, two other researchers worked in extracting data and quality assessment of the included literature. The primary outcomes were total effective rate. The secondary outcomes included electrocardiogram (EGG)effective rate, the effective rate of angina pectoris, fasting blood glucose (FBG), 2-h postprandial blood glucose (PBG), hemoglobinA1c (HbA1c), total cholesterol (TC) and triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), frequency of angina pectoris, and duration of angina pectoris. We adopted stata16.0 software for the systematic review and network meta-analysis. Results: A total of 53 trials involved 4,619 patients and one of the following 16 traditional Chinese medicine injections: Danhong, Danshen, Gualoupi, Gegen, Chuanxiongqin, Danshenchuanxiongqin, Shenmai, Shenqi, Xixin, Xuesaitong, Shuxuetong, Guanxinning, Kudiezi, Ciwujia, Xingding, Shuxuening. The meta-analysis revealed that Chuanxiongqin injection was superior to all other therapies in improving the total effective rate, [vs. conventional therapy odds ratio (OR): 14.52, 95% confidence interval (CI): 4.13-51.02], vs. Xuesaitong injection (odds ratio: 7.61, confidence interval: 1.25-46.40), and vs. Danshenchuanxiongqin injection (odds ratio: 3.98, confidence interval: 1.03-15.28)]. Xixin injection + conventional therapy was superior to conventional therapy only for electrocardiogram effective rate (odds ratio: 5.44, confidence interval: 1.55-19.18). Shenmai injection + conventional therapy was superior to conventional therapy in effective rate of angina (odds ratio: 11.05, confidence interval: 2.76-44.28). There was not different significantly in the comparisons of frequency of angina pectoris and duration of angina pectoris, we considered that this may be due to the lack of sufficient data. As most of the included RCTs did not monitor Adverse Events, the safety of those traditional Chinese medicine injections remains to be further explored. Conclusion: Basing on our study, traditional Chinese medicine injections combined with conventional therapy takes important role in the treatment of diabetes mellitus-coronary heart disease, and its curative effect is better than conventional therapy. Nevertheless, properly designed RCTs are required to validate our conclusions in the future.

Abstract
Cerebral ischemia threatens human health and life. Hyperlipidemia is a risk of cerebral ischemia. Danhong injection (DHI) is a traditional Chinese medical preparation for the treatment of cerebrovascular diseases. However, the effects of DHI on mitochondria-dependent apoptosis and mitochondrial function following cerebral ischemia in hyperlipidemia rats are not clear. In this study, SD rats were fed by high-fat diet for six weeks to establish the hyperlipidemia model, except for the sham and ischemia-reperfusion (I/R) groups. Hyperlipidemia rats were assigned into I/R + high-fat diet (HFD) group, DHI 1 mL/kg group, and DHI 2 mL/kg group. DHI was administrated to the drug group via caudal vein for seven consecutive days (once per day). Subsequently, rats underwent middle cerebral artery occlusion (MCAO) for 1 h and reperfusion for 24 h. The results showed that DHI significantly reduced cerebral infarction volume, ameliorated neurological function, improved pathological changes, and inhibited apoptosis. DHI could significantly restore the levels of mitochondrial respiratory chain complexes I-IV, increase the ATP content and COX activity, and decrease the level of OFR in the ischemic brain mitochondria of hyperlipidemia rats after I/R. DHI significantly regulated the levels of cytochrome c (Cyt c), Apaf1, Bax, Bcl-2, Caspase-3, and Caspase-9 in brain tissue, and improved mitochondrial dynamics (Mfn1, Mfn2, OPA1, Drp1, and Fis1). The results indicate that DHI could alleviate ischemic brain injury in hyperlipidemia rats, and the mechanism may be to improve mitochondrial function by restoring the mitochondrial respiratory chain and changing the protein balance of mitochondrial fusion and fission, and inhibiting mitochondria-dependent apoptosis.

Abstract
Ischemic stroke (IS) is a multifactorial and heterogeneous neurological disorder with high rate of death and long-term impairment. Despite years of studies, there are still no stroke biomarkers for clinical practice, and the molecular mechanisms of stroke remain largely unclear. The high-throughput omics approach provides new avenues for discovering biomarkers of IS and explaining its pathological mechanisms. However, single-omics approaches only provide a limited understanding of the biological pathways of diseases. The integration of multiple omics data means the simultaneous analysis of thousands of genes, RNAs, proteins and metabolites, revealing networks of interactions between multiple molecular levels. Integrated analysis of multi-omics approaches will provide helpful insights into stroke pathogenesis, therapeutic target identification and biomarker discovery. Here, we consider advances in genomics, transcriptomics, proteomics and metabolomics and outline their use in discovering the biomarkers and pathological mechanisms of IS. We then delineate strategies for achieving integration at the multi-omics level and discuss how integrative omics and systems biology can contribute to our understanding and management of IS.

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.

Abstract
Advanced glycation end products (AGEs) are characterized diabetic metabolites inducing macrophage M1 polarization which is crucial in diabetes-exacerbated atherosclerosis. Matrine was proved anti-atherosclerotic. The current study was aimed to investigate the inhibitory effects of matrine on AGEs- induced macrophage M1 polarization and underlying molecular mechanisms. Primary mouse macrophages were exposed to AGEs. Receptor for AGEs (RAGE) and toll-like receptor 4 (TLR4) were over-expressed by vectors. Matrine was used to treat these cells. Inducible nitric oxide synthase (iNOS) expression and pro-inflammatory cytokine production were used to evaluate macrophage M1 polarization. Oxidative stress was assessed by intracellular reactive oxygen species (ROS) generation, total antioxidant capacity (TAC) and malondialdehyde (MDA) contents. Relative mRNA expression level was determined by real-time PCR. Western blotting was used to evaluate protein and protein phosphorylation levels. Bisulfite sequencing PCR (BSP) was used to evaluate DNA methylation. Matrine reduced AGEs exposure-elevated expressions of DNA methyltransferase (DNA MTase, DNMT)3a and DNMT3b in macrophages which were not affected by RAGE or TLR4 over expressions. DNA methylation rate of GPX1 promoter was reduced from 97.22% to 66.67% in AGEs- exposed macrophages treated by matrine. GPX1 expression was up-regulated by matrine, which further suppressed AGEs/RAGE-mediated oxidative stress. Thus, the activation of down-stream TLR4/STAT1 signaling pathway was inhibited by matrine treatment which eventually suppressed AGEs- induced macrophage M1 polarization. However, these effects of matrine were impaired by RAGE and TLR4 overexpression. Results from this study suggested that matrine inhibited AGEs- induced macrophage M1 polarization by suppressing RAGE-induced oxidative stress-mediated TLR4/STAT1 signaling pathway. Matrine exerted anti-oxidant effects via increasing GPX1 expression by inhibiting DNMT3a/b-induced GPX1 promoter DNA methylation.

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: Community-acquired bacterial pneumonia (CABP) is an important health care concern in the worldwide, and is associated with significant morbidity, mortality, and health care expenditure. Streptococcus pneumoniae is the most frequent causative pathogen of CABP. Common treatment for hospitalized patients with CABP is empiric antibiotic therapy using β-lactams in combination with macrolides, respiratory fluoroquinolones, or tetracyclines. However, overuse of antibiotics has led to an increased incidence of drug-resistant S. pneumoniae, exacerbating the development of community-acquired drug-resistant bacterial pneumonia (CDBP) and providing a challenge for physicians to choose empirical antimicrobial therapy. Methods: Traditional Chinese medicine (TCM) is widely used as a complementary treatment for CDBP. Yinhuapinggan granules (YHPG) is widely used in the adjuvant treatment of CDBP. Experimental studies and small sample clinical trials have shown that YHPG can effectively reduce the symptoms of CDBP. However, there is a lack of high-quality clinical evidence for the role of YHPG as a complementary drug in the treatment of CDBP. Here, we designed a randomized, double-blind, placebo-controlled clinical trial to explore the efficacy and safety of YHPG. A total of 240 participants will be randomly assigned to the YHPG or placebo group in a 1:1 ratio. YHPG and placebo will be added to standard treatment for 10 days, followed by 56 days of follow-up. The primary outcome is the cure rate of pneumonia, and the secondary outcomes includes conversion rate of severe pneumonia, lower respiratory tract bacterial clearance, lactic acid (LC) clearance rate, temperature, C-reactive protein (CRP), criticality score (SMART-COP score), acute physiological and chronic health assessment system (APACHEII score) and clinical endpoint events. Adverse events will be monitored throughout the trial. Data will be analyzed according to a pre-defined statistical analysis plan. This research will disclose the efficacy of YHPG in acquired drug-resistant pneumonia. Clinical Trial Registration: https://clinicaltrials.gov, identifier ChiCTR2100047501.

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
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
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.

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
Mannitol, a representative of hyperosmolar therapy, is indispensable for the treatment of malignant cerebral infarction, but its therapeutic effect is limited by its exacerbation of blood-brain barrier (BBB) disruption. This study was to explore whether Danhong injection (DHI), a standardized product extracted from Salvia miltiorrhiza Bunge and Carthamus tinctorius L., inhibits the destructive effect of mannitol on BBB and thus enhancing the treatment of hemispheric ischemic stroke. SD rats were subjected to pMCAO followed by intravenous bolus injections of mannitol with/without DHI intervention. Neurological deficit score, brain edema, infarct volume at 24 h after MCAO and histopathology, microvascular ultrastructure, immunohistochemistry and immunofluorescence staining of endothelial cell junctions, energy metabolism in the ischemic penumbra were assessed. Intravenous mannitol after MCAO resulted in a decrease in 24 h mortality and cerebral edema, whereas no significant benefit on neurological deficits, infarct volume and microvascular ultrastructure. Moreover, mannitol led to the loss of endothelial integrity, manifested by the decreased expression of occludin, junctional adhesion molecule-1 (JAM-1) and zonula occluden-1 (ZO-1) and the discontinuity of occludin staining around the periphery of endothelial cells. Meanwhile, after mannitol treatment, energy-dependent vimentin and F-actin, ATP content, and ATP5D expression were down-regulated, while MMP2 and MMP9 expression increased in the ischemic penumbra. All the insults after mannitol treatment were attenuated by addition of intravenous DHI. The results suggest DHI as a potential remedy to attenuate mannitol-related BBB disruption, and the potential of DHI to upregulate energy metabolism and inhibit the activity of MMPs is likely attributable to its effects observed.

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.

Abstract
Danhong injection (DHI) is a compound Chinese medicine widely used in China for treatment of ischemic cardio-cerebrovascular diseases. However, limited data are available regarding the protective effect of DHI on the ischemic penumbra in ischemic stroke. This study aimed to investigate the effect of intravenous DHI on neuronal injure in the ischemic penumbra after cerebral ischemia/reperfusion (CI/R), focusing especially on the involvement of intracellular energy metabolism coupling. Male Sprague-Dawley rats were subjected to right middle cerebral artery occlusion for 60 min followed by reperfusion with or without intravenous DHI (0.5, 1.0, or 2.0 mL/kg) once daily for 7 days. Post-treatment with DHI ameliorated neurological defects, diminished cerebral infarction, alleviated cerebral edema, improved microcirculatory perfusion after 7days of reperfusion, and inhibited apoptosis and enhanced neuronal survival in the ischemic penumbra. In addition, DHI significantly ameliorated oxidative stress, reduced DNA damage, and inhibited the activation of PARP1/AIF pathway, thereby restoring cytoplasmic glycolytic activity. Furthermore, this drug increased PDH activity by inhibiting the HIF1α/PDK1 signaling pathway, thus eliminating the inhibitory effect of CI/R on mitochondrial metabolism. The results of this study suggest that DHI can alleviate cerebral edema after CI/R and rescue the ischemic penumbra, and these protective effects are due to the regulation of intracellular energy metabolic coupling.

the country heart attack prevention project
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
ETHNOPHARMACOLOGICAL RELEVANCE Danhong injection (DHI) is a Chinese medical injection applied to the clinical treatment of cardiovascular diseases that has anti-inflammatory, antiplatelet aggregation and antithrombotic effects. This study aimed to explore the effects of DHI on dyslipidemia and cholesterol metabolism in high-fat diet-fed rats. METHODS Sprague Dawley (SD) rats were randomly divided into six groups: normal group (Normal); hyperlipidemia model group (Model); DHI-treated groups at doses of 1.0 mL/kg, 2.0 mL/kg, 4.0 mL/kg; and simvastatin positive control group (2.0 mg/kg). The hypolipidemic effects of DHI were evaluated by measuring serum lipid levels, hepatic function and oxidative stress, respectively. And pathological changes in liver tissues were determined using hematoxylin-eosin (H&E) and oil red O staining. Moreover, the mRNA and protein expression levels of cholesterol metabolism related genes were detected by real-time PCR (RT-PCR) and Western blot. RESULTS Compared with the Model group, DHI treatment markedly decreased the liver index and improved the pathological morphology of liver tissues. DHI treatment dose-dependently decreased the levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), malondialdehyde (MDA), and free fatty acids (FFA) in serum or liver tissues (P < 0.01 or P < 0.05), and increased the high-density lipoprotein cholesterol (HDL-C) and tripeptide glutathione (GSH) (P < 0.01 or P < 0.05). The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) were increased in the DHI-treated groups (P < 0.01 or P < 0.05), while the alanine transaminase (ALT) and aspartate transaminase (AST) were decreased (P < 0.01 or P < 0.05). Furthermore, the expression levels of LDL receptor (LDLR), cholesterol 7-α-hydroxylase (CYP7A1), liver X receptor α (LXRα), and peroxisome proliferator-activated receptor α (PPARα) were dose-dependently upregulated in the DHI-treated groups, whereas the expression of sterol regulatory element-binding protein-2 (SREBP-2) was downregulated. CONCLUSIONS Our study demonstrated that DHI markedly ameliorated hyperlipidemia rats by regulating serum lipid levels, inhibiting hepatic lipid accumulation and steatosis, improving hepatic dysfunction, and reducing oxidative stress. The potential mechanism was also tentatively investigated and may be related to the promotion of bile acid synthesis via activation of the PPARα-LXRα-CYP7A1 pathway. Therefore, DHI could be regarded as a potential hypolipidemic drug for the treatment of hyperlipidemia.

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
Neuroinflammation is one of the major causes of damage of the central nervous system (CNS) and plays a vital role in the pathogenesis of cerebral ischemia, which can result in long-term disability and neuronal death. Danhong injection (DHI), a traditional Chinese medicine injection, has been applied to the clinical treatment of cerebral stoke for many years. In this study, we investigated the protective effects of DHI on cerebral ischemia-reperfusion injury (CIRI) in rats and explored its potential anti-neuroinflammatory properties. CIRI in adult male SD rats was induced by middle cerebral artery occlusion (MCAO) for 1 h and reperfusion for 24 h. Results showed that DHI (0.5, 1, and 2 ml/kg) dose-dependently improved the neurological deficits and alleviated cerebral infarct volume and histopathological damage of the cerebral cortex caused by CIRI. Moreover, DHI (0.5, 1, and 2 ml/kg) inhibited the mRNA expressions of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), intercellular cell adhesion molecule-1 (ICAM-1), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS) in ischemic brains, downregulated TNF-α, IL-1β, and monocyte chemotactic protein-1 (MCP-1) levels in serum, and reduced the neutrophil infiltration (myeloperoxidase, MPO) in ischemic brains, in a dose-dependent manner. Immunohistochemical staining results also revealed that DHI dose-dependently diminished the protein expressions of ICAM-1 and COX-2, and suppressed the activation of microglia (ionized calcium-binding adapter molecule 1, Iba-1) and astrocyte (glial fibrillary acidic protein, GFAP) in the cerebral cortex. Western blot analysis showed that DHI significantly downregulated the phosphorylation levels of the proteins in nuclear factor κB (NF-κB) and mitogen-activated protein kinas (MAPK) signaling pathways in ischemic brains. These results indicate that DHI exerts anti-neuroinflammatory effects against CIRI, which contribute to the amelioration of CNS damage.

Abstract
Objective: To systematically analyze the impact of PM2.5 exposure on children's behavior. Methods: Use air pollution, fine particulate matter, children, students, child behavior, neurobehavior, attention, autism, autism spectrum disorder, attention deficit hyperactivity disorder, hyperactivity, and bad behavior as Chinese keywords. Use air pollution, fine particulate matter, particulate matter, PM2.5, children, student, behavior, autism, attention, intention, neurobehavior, attention deficit hyperactivity disorder, ADHD, ASD as English keywords. Journal papers and grey literature were searched from CNKI, Wanfang Data Knowledge Service Platform, PubMed and Web of Science database from their inception to Nov 2019, which are related to PM2.5 and children behavior problems. The search period is as of November 2019, and the languages are limited to Chinese and English. The inclusion criteria included the exposure factor of the study as PM2.5; the results of the study included behavioral disorders and related diseases; the languages of the included literature were Chinese and English; original research papers; case-control, cohort or cross-sectional studies. 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
The characteristics of dissolved organic matter (DOM) formed in aerobic and anaerobic digestion of waste-activated sludge (WAS) after ozone pretreatment were investigated with three ozone dosages (4.72, 10.96, and 13.8 mg O3/min) and four ozonation times (0, 10, 20, and 30 min) using six aerobic and six anaerobic digestion reactors. High decreasing rate of volatile suspended solid/total suspended solid indicated enhanced destruction of volatile solids and efficient sludge reduction. The results of TOC and UV absorbance indicated that increasing ozone dosage and time significantly enhanced hydrolysis and degradation of DOM. Data analysis with a first-order sequential reaction model revealed that, for aerobic digestion, kh increased in the range of 0.00049-0.00154 day-1; and for anaerobic digestion of WAS, kh increased in the range of 0.00302-0.00796 day-1 and kd increased in the range of 0.24910-0.54548 day-1. Detailed analysis of the composition of DOM showed that ozone pretreatment increased irreversible membrane resistance (IMR) and enhanced the breakdown of large DOM molecules, the formation of aromatic proteins, and tryptophan- and tyrosine-aromatic amino acids, as well as the accumulation of humic acid- and fulvic acid-like substances.

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.
