Abstract
We present the formation of quasi-periodic cool spicule-like jets in the solar atmosphere using 2.5-D numerical simulation in two-fluid regime (ions+neutrals) under the presence of thermal conduction and ion-neutral collision. The nonlinear, impulsive Alfvénic perturbations at the top of the photosphere trigger field aligned magnetoacoustic perturbations due to ponderomotive force. The transport of energy from Alfvén pulse to such vertical velocity perturbations due to ponderomotive force is considered as an initial trigger mechanism. Thereafter, these velocity perturbations steepen into the shocks followed by quasi-periodic rise and fall of the cool jets transporting mass in the overlying corona. This article is part of the theme issue 'Partially ionized plasma of the solar atmosphere: recent advances and future pathways'.

Abstract
OBJECTIVE Flow diverter stents (FDSs) have attracted interest for intracranial aneurysm (IA) treatment; however, occlusion of side branches and related complications have been reported. This study aimed to investigate the effects of FDSs in IA management when different branches of intracranial arteries are covered. MATERIALS AND METHODS A cross-sectional study was conducted using PUBMED, Embase, Web of Science, and Cochrane databases to include randomized or nonrandomized comparative-designed studies from January 2000 to August 2022 which reported outcomes of occlusion/narrowing of branches after IA treatment using FDSs. The PRISMA guidelines were used for our report. A random-effects meta-analysis was conducted to pool the outcomes, which included incidence rates of occlusion/narrowing of FDS-covered branches, branch occlusion-related symptoms, obliteration of IAs, and ideal clinical outcomes (modified Rankin Scale score ≤2). RESULTS The authors identified 57 studies involving 3789 patients with IA managed by FDSs covering different branches. During the median imaging follow-up at 12 months, the IA obliteration rate was satisfactory (>70%) when covering the ophthalmic artery (OA), posterior communicating artery (PComA), anterior choroidal artery (AChoA) or anterior cerebral artery (ACA), but not the middle cerebral artery-M2 segment (MCA-M2; 69.5%; 95% CI: 60.8-77.5%) and posterior inferior cerebellar artery (PICA; 59.1%, 13/22). The overall ideal clinical outcome was observed in 97.4% of patients (95% CI: 95.5-98.9%). Higher rates of occlusion/narrowing of branches were identified when FDSs covered the ACA (66.6%; 95% CI: 45.1-85.3%), PComA (44.3%; 95% CI: 34.2-54.6%), or MCA-M2 (39.2%; 95% CI: 24.5-54.7%); the risks were lower when covering the OA (11.8%; 95% CI: 8.8-15.1%), PICA (6.8%; 95% CI: 1.5-14.5%), and AchoA (0.5%; 95% CI: 0.0-2.9%). The risk of branch occlusion-related complications was low (incidence rate <5%) for each of the six evaluated branches. CONCLUSIONS Acceptable outcomes were identified following treatment of IAs when FDSs were placed across each of the six studied cerebral arteries. Treatment decisions regarding FDS placement across branch arteries should be made with the risk of complications from branch occlusion in mind.

Abstract
BACKGROUND A scientific and comprehensive analysis of the current status and trends in the field of cancer-associated fibroblast (CAF) research is worth investigating. This study aims to investigate and visualize the development, research frontiers, and future trends in CAFs both quantitatively and qualitatively based on a bibliometric approach. METHODS A total of 5518 publications were downloaded from the Science Citation Index Expanded of Web of Science Core Collection from 1999 to 2021 and identified for bibliometric analysis. Visualized approaches, OriginPro (version 9.8.0.200) and R (version 4.2.0) software tools were used to perform bibliometric and knowledge-map analysis. RESULTS The number of publications on CAFs increased each year, and the same tendency was observed in the RRI. Apart from China, the countries with the largest number of publications and the most cited frequency were mainly Western developed countries, especially the USA. Cancers was the journal with the largest number of articles published in CAFs, and Oncology was the most popular research orientation. The most productive author was Lisanti MP, and the University of Texas System was ranked first in the institutions. In addition, the topics of CAFs could be divided into five categories, including tumor classification, prognostic study, oncologic therapies, tumor metabolism and tumor microenvironment. CONCLUSIONS This is the first thoroughly scientific bibliometric analysis and visualized study of the global research field on CAFs over the past 20 years. The study may provide benefits for researchers to master CAFs' dynamic evolution and research trends.

Abstract
Background Spinal cord injury (SCI) is defined as traumatic damage to the spinal cord, affecting over three million patients worldwide, and there is still no treatment for the injured spinal cord itself. In recent years, immunology research on SCI has been published in various journals. Methods To systematically analyze the research hotspots and dynamic scientific developments of immunology research in SCI, we conducted a bibliometric and knowledge map analysis to help researchers gain a global perspective in this research field. Results The bibliometric study we completed included 1788 English-language papers published in 553 journals by 8861 authors from 1901 institutions in 66 countries/regions. Based on the references and keyword analysis, researchers in the past 10 years have mainly focused on the research directions of "monocyte chemoattractor protein 1," "nitric oxide," "pain," and "nitric oxide synthase" related to immunological research in SCI. However, with the development of other new directions such as "extracellular vesicles" (2019-2022), "Regenerative medicine" (2019-2022), "stromal cells" (2018-2022), "motor recovery" (2019-2022), and "glial activation" (2019-2022). Researchers prefer to study the application of regenerative strategies in SCI, the mechanism of extracellular vesicles in the development of SCI, the activation of spinal glial cells in SCI, and the pathways of motor recovery. This bibliometric analysis of immunology research in SCI summarizes the current status of this research field. The relationship between extracellular vesicles, regenerative medicine, stromal cells, motor recovery, and glial activation is currently a major research frontier. Further research and cooperation worldwide need to be enhanced. Conclusion We believe that our research can help researchers quickly grasp the current hotspot of immunology research in SCI and determine a new direction for future research.

Abstract
BACKGROUND The role and extent of the effects of short-term behavioral factors on the risk of hemorrhagic stroke (HS) are unclear. This study aimed to assess and quantify behavioral trigger factors (BTFs) for HS and identify the differences in BTFs between Chinese and other populations. METHODS A case-crossover study was performed from March 2021 to February 2022. New-onset HS patients were recruited from two university hospitals in China. The patients were interviewed to evaluate their exposure to 20 potential BTFs during the predefined risk and control periods and to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). A comprehensive literature review was conducted to synthesize the evidence. RESULTS A total of 284 patients with HS were included (150 with intracerebral hemorrhage and 134 with subarachnoid hemorrhage). Multivariate regression analysis showed that straining for defecation (OR: 3.06; 95% CI: 1.01-8.40), weightlifting (OR: 4.82; 95% CI: 1.02-22.83), overeating (OR: 4.33; 95% CI: 1.24-15.21), heavy physical exertion (OR: 3.02; 95% CI: 1.18-7.78), and chess/cards/mahjong games (OR: 2.51; 95% CI: 1.05-6.01) were associated with an increased risk within 2 hours before HS onset, and critical life events (OR: 3.81; 95% CI: 1.06-13.74) were associated with an increased risk 7 days before the onset of HS. Exposure to anger (OR: 3.17; 95% CI: 1.73-5.81) and heavy physical exertion (OR: 2.12; 95% CI: 1.65, 2.74) showed an increased risk of HS events after the pooled analysis. CONCLUSIONS Several behavioral activities and mood modifications are associated with the onset of HS. In addition to the common BTFs, Chinese patients have specific BTFs due to their habits and customs distinct from those of different populations in other regions. Key messages What is already known on this topic It is known that several behavioral trigger factors (BTFs) are associated with the onset of hemorrhagic stroke (HS), such as vigorous physical exercise and anger. Evidence for other potential trigger factors was of less robustness. Which BTFs contribute to HS among the Chinese population is poorly understood, since individuals in different countries and regions have their own habits of life and customs. What this study adds Our study identified that two special behaviors, chess/card/mahjong games and critical life events, were associated with the onset of HS in Chinese populations, besides heavy physical exertion, weightlifting, overeating, and straining for defecation, which were previously reported in other populations. Heavy physical exertion and anger could potentially increase the risk of HS based on a comprehensive aggregation and evidence synthesis. How this study might affect research, practice, or policy Patients in different populations or regions may possess specific BTFs owing to their distinct habits and customs. Avoidance of these behaviors and regulation of emotions to maintain a steady mentality would help minimize exposure and prevent the disease for high-risk populations in China.

Abstract
BACKGROUND This study aimed to assess whether pregnancy and puerperium were associated with the risk of brain arteriovenous malformation (bAVM) haemorrhage. METHODS A retrospective review was conducted in Xiangya Hospital, Central South University from January 2012 to December 2021. A case-crossover design was adopted to calculate the incidence density of bAVM-related haemorrhage among female patients in risk (pregnancy and puerperium) and control (non-pregnancy and non-puerperium) periods, according to four scenarios observed in different populations (scenario I: patients with haemorrhagic bAVM of all ages; scenario II: patients with haemorrhagic bAVM of all ages, with at least one previous pregnancy; scenario III: patients with haemorrhagic bAVM who are of reproductive age (15-45 years); scenario IV: patients with haemorrhagic bAVM of reproductive age (15-45 years), with at least one previous pregnancy. Next, a comprehensive literature aggregation (up to April 2022) was performed for evidence synthesis. RESULTS Among the 311 female patients with haemorrhagic bAVM, a significant haemorrhage risk during pregnancy and puerperium was found in Scenarios I (relative risk [RR], 2.08; 95% CI, 1.28 to 3.39), II (RR, 3.21; 95% CI, 1.95 to 5.31) and IV (RR, 2.92; 95% CI, 1.73 to 4.93); however, a suggestive risk was found in scenario III (RR, 1.62; 95% CI, 0.99 to 2.67). Evidence synthesis revealed a consistent haemorrhage risk among patients of all ages (RR, 3.15; 95% CI, 1.93 to 5.15) and those of reproductive age (RR, 1.29; 95% CI, 0.89 to 1.86). CONCLUSION Compared with most previous studies, a higher but relatively moderate risk for bAVM-related haemorrhage was identified during pregnancy and puerperium. Individualised prevention and treatment strategies should be preferred when neurosurgeons make clinical decisions.

Abstract
OBJECTIVE To investigate the protective effects of total saponins from Panax japonicus (TSPJ) against high-fat dietinduced testicular Sertoli cell junction damage in mice. METHODS Forty male C57BL/6J mice were randomized into normal diet group, high-fat diet group, and low-dose (25 mg/kg) and high-dose (75 mg/kg) TSPJ treatment groups (n=10). The mice in the normal diet group were fed a normal diet, while the mice in the other groups were fed a high-fat diet. After TSPJ treatment via intragastric administration for 5 months, the testes and epididymis of the mice were collected for measurement of weight, testicular and epididymal indices and sperm parameters. HE staining was used for histological evaluation of the testicular tissues and measurement of seminiferous tubule diameter and seminiferous epithelium height. The expression levels of ZO-1, occludin, claudin11, N-cadherin, E-cadherin and β-catenin in Sertoli cells were detected with Western blot, and the localization and expression levels of ZO-1 and β-catenin in the testicular tissues were detected with immunofluorescence assay. The protein expressions of LC3B, p-AKT and p-mTOR in testicular Sertoli cells were detected using double immunofluorescence assay. RESULTS Treatment with TSPJ significantly improved high-fat diet-induced testicular dysfunction by reducing body weight (P < 0.001), increasing testicular and epididymal indices (P < 0.05), and improving sperm concentration and sperm viability (P < 0.05). TSPJ ameliorated testicular pathologies and increased seminiferous epithelium height of the mice with high-fat diet feeding (P < 0.05) without affecting the seminiferous tubule diameter. TSPJ significantly increased the expression levels of ZO-1, occludin, N-cadherin, E-cadherin and β-catenin (P < 0.05) but did not affect claudin11 expression in the testicular tissues. Immunofluorescence assay showed that TSPJ significantly increased ZO-1 and β-catenin expression in the testicular tissues (P < 0.001), downregulated LC3B expression and upregulated p-AKT and p-mTOR expressions in testicular Sertoli cells. CONCLUSION TSPJ alleviates high-fat diet-induced damages of testicular Sertoli cell junctions and spermatogenesis possibly by activating the AKT/mTOR signaling pathway and inhibiting autophagy of testicular Sertoli cells.

Abstract
Background Genetic factors play important roles in the development of intracranial aneurysm (IA). Rare RNF213 variants have been identified as being susceptible to Moyamoya disease (MMD), non-MMD intracranial artery stenosis/occlusion disease, and other vascular disorders. This study aimed to investigate the association between rare RNF213 variants and the risk of IA in a Chinese population. Methods We recruited 174 patients with IA for RNF213 target exome sequencing. Information on the control subjects was obtained from the 1,000 Genome Project and GeneSky in-house database. After prioritizing rare RNF213 variants, the filtered variants were confirmed by Sanger sequencing. Gene-based association analyses were performed to identify the association between variants and the disease using burden and variance component methods; that is, the weighted-sum statistic (WSS) and the sequence kernel association test (SKAT), respectively. The Student's t-test, Chi-squared test, and Fisher's exact test were used to compare the clinical characteristics between carriers and non-carriers of the RNF213 variants. Results After filtering, there were 14 RNF213 variants in 18 patients with IA, which were significantly associated with the disease after the gene-based association tests [minor allele frequency (MAF) <0.01, WSS P value 5.08×10-9; SKAT P value 2.96×10-6; SKAT-O P value 3.56×10-8]. Significant difference was not obtained between the carriers and non-carriers of the RNF213 variants in terms of the clinical characteristics. Conclusions Rare RNF213 variants were associated with sporadic IA in a Chinese population. Our findings suggest that these rare RNF213 variants might have potentially important roles in IA. However, more comprehensive studies need to be conducted to confirm this association and causality.

Abstract
Chaihu-Shugan-San (CSS) is a traditional botanical drug formula often prescribed to treat depression in oriental countries, but its pharmacotherapeutic mechanism remains unknown. It was recently reported that CSS alters the composition of intestinal microflora and related metabolites such as bile acids (BAs). Since the intestinal microflora affects physiological functions of the brain through the gut-microbiota-brain axis, herein we investigated whether CSS altered BA levels, gut microflora, and depression-like symptoms in chronic unpredictable mild stress (CUMS) mice, a well-established mouse model of depression. Furthermore, we determined whether BA manipulation and fecal microbiota transplantation altered CSS antidepressant actions. We found that the BA chelator cholestyramine impaired the antidepressant effects of CSS, which was partially rescued by dietary cholic acid. CSS increased the relative abundance of Parabacteroides distasonis in the colon of CUMS mice, and increased serum levels of various BAs including hyocholic acid (HCA) and 7-ketodeoxycholic acid (7-ketoDCA). Furthermore, gut bacteria transplantation from CSS-treated mice into untreated or cholestyramine-treated CUMS mice restored serum levels of HCA and 7-ketoDCA, alleviating depression-like symptoms. In the hippocampus, CSS-treated mice had decreased expression of genes associated with BA transport (Bsep and Fxr) and increased expression of brain-derived neurotrophic factor and its receptor, TrkB. Overall, CSS increases intestinal P. distasonis abundance, leading to elevated levels of secondary BAs in the circulation and altered expression of hippocampal genes implicated in BA transport and neurotrophic signaling. Our data strongly suggest that the gut microbiota-brain axis contributes to the potent antidepressant action of CSS by modulating BA metabolism.

Abstract
Objective: To investigate the efficacy, and safety of omalizumab in the treatment of eosinophilic granulomatous with polyangiitis (EGPA) with asthma as the first symptom. Method: The clinical characteristics of 22 EGPA patients with asthma as the first symptom treated with omalizumab in the First Affiliated Hospital of Guangzhou Medical University from March 2018 to December 2020 were retrospectively analyzed. The asthma control test (ACT) score, the frequency of asthma exacerbation (AE), the Birmingham Vasculitis Activity Score (BVAS), the variation rate of peak expiratory flow (PEF), the percentage of PEF to predicted value of PEF (PEFpred%), the percentage of forced expiratory volume in first second (FEV1) to predicted value of FEV1 (FEV1pred%), the dosage of oral corticosteroid (OCS) and other clinical data [M(Q1, Q3)] were collected before and after treatment, to observe the efficacy and adverse reactions of omalizumab. Results: There were 22 subjects recruited in this study. The median age was 42 (22-70) years. Eleven of the patients were males. After treated with omalizumab for 4 months, there were 68.2%(15/21) of patients who responded to the treatment. In the response group (n=15), the patients' ACT score increased from 19.0 (16.5, 21.0) to 23.0 (21.5, 24.0) (P=0.001). The frequency of AE decreased from 0.7 (0.3, 1.0) to 0 (0, 0.7) per four mouths (P<0.001). The BVAS decreased from 4.0 (2.0, 6.0) to 2.0 (2.0, 4.0) (P=0.007). The variation rate of PEF decreased from 18.8% (14.0%, 27.7%) to 9.2% (6.8%, 11.9%) (P=0.007). The PEFpred% increased from 80.8% (73.5%, 90.7%) to 100.5% (79.4%, 114.0%) (P=0.005). The maintenance dosage of OCS reduced from 15.0 (10.0, 20.0) mg/d to 8.8 (5.0, 10.0) mg/d (P=0.005). The level of baseline eosinophil in peripheral blood of patients in non-response group was higher than that in response group [11.4% (9.2%, 22.6%) vs 3.4% (1.1%, 6.5%), P<0.05]. A total of 190 injections were performed in 22 patients, and only 4 patients (2.1%) had adverse reactions after a single injection of omalizumab, such as dizziness, swelling of injection site and pruritus. The adverse reactions were tolerable. Conclusions: Omalizumab has certain curative effect on EGPA, can reduce asthmatic symptoms and OCS maintenance dosage, and has a good safety profile. The rate of response to the treatment is higher in patients with mild eosinophilic inflammation.

Abstract
Background Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating disease caused by intracranial aneurysm (IA) rupture. Lysyl oxidase (LOX) family genes (LOX-like [LOXL] 1-4) have roles in collagen cross-linking in the extracellular matrix (ECM) and may be associated with IA rupture. We aimed to explore the association between LOX polymorphisms and the risk of aSAH. Methods This case-control study included 2 cohorts: 133 single ruptured and 115 unruptured IA patients, and 65 multiple ruptured and 71 unruptured IA patients. Genotyping of 27 single nucleotide polymorphisms (SNPs) in LOX was performed. Logistic regression analysis was performed to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) of the SNPs of LOX and the risk of aSAH. Results LOX rs1800449 and LOXL4 rs3793692 were positively associated with the risk of single IA rupture in the recessive model (OR =5.66, 2.06; 95% CI =1.22–26.24, 1.11–3.82, respectively) and LOX rs10519694 demonstrated a protective effect on single IA rupture (dominant model: OR =0.42, 95% CI =0.21–0.83; recessive model: OR =0.16, 95% CI =0.04–0.65; additive model: OR =0.46, 95% CI =0.28–0.78). LOXL1 rs2165241, LOXL2 rs1063582, and LOXL3 rs17010021 showed risk effects on multiple IAs rupture. LOXL3 rs17010022 showed a protective effect on multiple IAs ruptures (dominant model: OR =0.41, 95% CI =0.21–0.82; additive model: OR =0.51, 95% CI =0.30–0.85). Conclusions LOX and LOXL4 may be susceptibility genes for single IA rupture, whereas LOXL1-3 may have a role in susceptibility to multiple IAs ruptures in the Chinese population, suggesting that LOX family genes may be associated with aSAH.

Abstract
Objective: To describe the characteristics of molecular transmission network of newly diagnosed HIV-1 infected patients, analyze their risk factors related to network access and provide a scientific basis for precise prevention of HIV infection. Methods: For 340 blood samples collected from confirmed HIV-1 infection cases aged ≥50 years in Pengzhou city of Sichuan province from April 2019 to August 2021, nested PCR amplification was used to amplify, clean up and splice clips the pol gene region. The phylogenetic tree was constructed by multi-sequence comparison to distinguish subtypes, and the pairwise genetic distance was calculated. When the genetic distance threshold was 0.90%, the number of clusters was the largest (41), and the molecular transmission network was constructed.The χ2 test and logistic regression analysis were performed.The software SPSS 19.0 was used for statistical analysis. Results: A total of 340 samples were successfully amplified (97.06%, 330/340) in 330 samples. 6 HIV-1 subtypes identified, including:CRF01_AE(56.67%,187/330), CRF07_BC(27.88%,92/330), B(11.21%,37/330), CRF08_BC(3.33%,11/330), CRF55_01B(0.61%,2/330) and C(0.30%,1/330).The network entry rate was 58.79% (194/330).The results of logistic regression analysis of the risk factors of HIV-1 molecular transmission network in the research subjects showed that compared with illiteracy, junior high school (OR=0.35, 95%CI:0.13-0.97) and high school/technical secondary school (OR=0.14, 95%CI: 0.02-0.97) had lower possibility of network entry. Compared with farmers, unknown occupations (OR=0.40,95%CI: 0.17-0.95) are less likely to enter the network .Compared with CRF01_AE, CRF07_BC (OR=0.20, 95%CI: 0.11-0.35) and CRF08_BC subtype (OR=0.09, 95%CI: 0.02-0.45) were less likely to enter the network. Conclusions: The sources of AIDS transmission among middle-aged and elderly people of rural areas are diversified in Pengzhou city of Sichuan province. AIDS intervention should focus on middle-aged and elderly farmers with low educational level, and strengthen detection and traceability investigation.

Abstract
Background and Purpose Stroke is a serious fatal and disabling disease. Stroke-associated pneumonia (SAP) is the most common complication of stroke, which may further aggravate the stroke. The prevention and early prediction of SAP is a key clinical strategy. 15-hydroxyprostaglandin dehydrogenase (15-PGDH) is involved in pneumonia, while its relationship with SAP has yet to be determined. Therefore, we investigated the predictive value of 15-PGDH for SAP and visualized their relationship. Methods Stroke patients were recruited and divided into SAP group and Non-SAP group. Baseline demographic and clinical data were obtained from the medical record system, blood samples were collected to detect relevant variables and 15-PGDH levels. Patient characteristics were compared with a t-test. Binary logistic regression analysis was performed to determine the predictive value of 15-PGDH for SAP. Restricted cubic splines (RCS) were performed to visualize the relationship between 15-PGDH and SAP risk. Finally, the SAP patient characteristics between the severe group and mild group were compared. Results 50 patients were enrolled and divided into SAP group (n = 26) and Non-SAP group (n = 24). 15-PGDH in the SAP group was lower than that in the Non-SAP group (0.258 ± 0.275 vs. 0.784 ± 0.615, p = 0.025). Binary logistic regression analysis revealed that the lower 15-PGDH, the higher the risk of SAP (OR = 0.04, 95%CI, 0.010–0.157, p < 0.001). The RCS model showed the L-shaped relationship between 15-PGDH and SAP. Conclusions In stroke patients, serum 15-PGDH is a valuable biomarker for predicting SAP. There is an L-shaped relationship between the level of 15-PGDH and the risk of SAP.

Background
Inflammation plays a crucial role in coronary atherosclerosis progression, and growing evidence has demonstrated that the fibrinogen-to-albumin ratio index (FAR) is associated with the severity of coronary artery disease (CAD). However, the long-term risk of cardiovascular events remains indistinct in patients with different level of FAR and different glycemic metabolism status. This study was to access 5-year clinical outcomes of diabetic and non-diabetic patients who underwent percutaneous coronary intervention (PCI) with different level of FAR.

We consecutively enrolled 10,724 patients with CAD hospitalized for PCI and followed up for major adverse cardiac and cerebrovascular events (MACCE) covering all-cause mortality, non-fatal myocardial infarction, non-fatal ischemic stroke and unplanned coronary revascularization. FAR was computed using the following formula: Fibrinogen (mg/dL) / Albumin (g/L). According to the optimal cut-off value of FAR, which was determined by the surv_cutpoint function of the R package survminer via RStudio software (version 2021.09.0), patients were divided into higher level of FAR (FAR-H) and lower level of (FAR-L) subgroups, and were further categorized into for groups as FAR-H with DM and non-DM, and FAR-L with DM and non-DM.
Results
5,298 patients (58.36 ± 10.36 years, 77.7% male) were ultimately enrolled in the present study. A total of 1,099 (20.7%) MACCEs were documented during the 5-year follow-up. The optimal cut-off value of FAR was 0.0783 by the surv_cutpoint function. Compared to ones with FAR-H and DM, patients with FAR-L and non-DM, FAR-H and non-DM, FAR-L and DM had decreased risk of MACCEs [adjusted hazard ratio (HR): 0.75, 95% confidence interval (CI) 0.64-0.89, p = 0.001; HR: 0.006, 95% CI 0.66-0.93, p = 0.006; HR: 0.81, 95% CI 0.68-0.97, p = 0.019]. Notably, non-diabetic patients with lower level of FAR also had lower all-cause mortality risk than those in the FAR-H/DM group (HR: 0.41, 95% CI 0.27-0.63, p < 0.001). Multivariate Cox proportional hazards regression analysis also indicated the highest risk of MACCEs in patients with FAR-H and DM than others (p for trend = 0.005). In addition, subgroup analysis revealed consistent effects on 5-year MACCE across various subgroups.
Conclusion
Diabetic patients with higher level of FAR had the worse 5-year outcomes compared with patients in other three groups. The level of FAR may help to identify high-risk individuals in this specific population.

Abstract
BACKGROUND The pathogenic mechanism of brain arteriovenous malformation (bAVM) is poorly understood. A growing body of evidence indicates that genetic factors play crucial roles in bAVM. This study examined genetic variants associated with bAVM through quantitative synthesis and qualitative description of literature. METHODS Five databases were searched to gather potentially relevant articles published up to January 2022. STATA 14.0 software was used for statistical analyses. Pooled odds ratios and 95% confidence intervals were calculated with random effect models, and heterogeneity was assessed using the Cochran Q test and quantified with the I 2 test. Sensitivity and publication bias were analyzed to test the robustness of the associations. Variants identified in only one study or with great heterogeneity were not suitable for pooling association analysis, and therefore a qualitative systematic review was performed. RESULTS In total, 30 papers were included in a systematic review involving 4709 cases and 7832 controls, where 17 papers were in a meta-analysis. A suggested association of bAVM was observed with ACVRL1 rs2071219 in the additive model and CDKN2B-AS1 rs1333040 in the recessive and additive models. Other variants of genes that could not be analyzed were summarized by qualitative description. These genes were mostly involved in bone morphogenic protein/transforming growth factor beta (BMP/TGF-β), vascular endothelial growth factor/vascular endothelial growth factor receptor (VEGF/VEGFR), and RAS-mitogen activated protein kinase (MAPK) signaling and inflammation. CONCLUSIONS According to our meta-analysis, ACVRL1 rs2071219 and CDKN2B-AS1 rs1333040 were potentially associated with bAVM. Multiple pathological signaling pathways could affect disease development. Future studies should aim to determine the interaction of candidate genes with environmental risk factors and to elucidate detailed mechanisms of action of variants and genes.1.

Abstract
Objective: To establish the morphological reference values for the differential count of white blood cells in peripheral blood smear as well as nucleated cells and megakaryocytes in bone marrow smear. Methods: From April 2012 to June 2020, 4 221 healthy donors for hematopoietic stem cell transplantation in Hebei Yanda Lu Daopei Hospital were selected. The median age was 36 (3-72) years old, including 2 520 males and 1 701 females. They were divided into four groups according to age: children group, with age≤14 years old [n=334, 11 (3-14) years old], youth group, with age >14 years old and <45 years old [n=2 855, 33 (15-44) years old], middle-aged adult group, with age ≥45 years old and < 60 years old [n=929, 49 (45-59) years old], and older adult group, with age ≥60 years old [n=103, 62 (60-72) years old]. Gender subgroups were established in each age group. According to different hematopoietic characteristics, the children group were divided into two subgroups: children group 1 [n=48, 6 (3-7) years old] and children group 2 [n=286, 11 (8-14) years old]. According to the clinical routine, 100 white blood cells in peripheral blood, 200 nucleated cells in bone marrow, and cell numbers/4.5 cm2 for megakaryocytes were classified and counted. The results of cell count in different age and gender groups were compared, and the reference values of morphological classification were established for different groups with statistical or clinical significance. Results: Due to the existence of statistically significant differences between children and adult groups and different gender subgroups in adults (all P<0.05), the reference values were established for children group and adult gender subgroups. The counts of segmented neutrophils and lymphocytes in peripheral blood were 46.65(43.97-49.32)% and 44.00(10.60-65.10)% in children group 1, 50.73(49.50-51.96)% and 39.55 (38.36-40.74)% in children group 2, and 57.00 (39.00-75.23) % and 33.00 (17.00-52.00) % in adult group, respectively. Bone marrow segmented neutrophils, orthochromatic erythroblasts, and mature lymphocytes were 11.54 (10.68-12.41)%, 14.20 (13.19-15.21)%, and 23.99 (22.06-25.92)% in children group 1, 12.50 (7.00-21.50)%, 15.00(9.50-25.50)%, and 21.02 (20.24-21.81)% in children group 2, 13.50 (7.50-21.00)%, 16.50 (10.50-26.00)%, and 15.50 (7.50-26.00)% in adult male group, and 14.50 (8.00-24.50)%, 14.50 (9.00-23.00)%, and 17.50 (8.50-29.00)% in adult female group, respectively. The myelopoiesis/erythropoiesis ratio in children group, adult male group and adult female group was 1.86∶1 (1.14∶1-3.23∶1), 1.96∶1 (1.12∶1-3.19∶1), 2.22∶1 (1.30∶1-3.69∶1), respectively. The numbers of granular megakaryocytes and thromocytogenic megakaryocytes were 138 (25-567) cells/4.5cm2 and 86 (13-328) cells/4.5 cm2 in children group, and 92 (13-338) cells/4.5 cm2 and 38 (3-162) cells/4.5 cm2 in adult group, respectively. Conclusion: The morphological reference values for the differential count of white blood cells in peripheral blood smear as well as nucleated cells and megakaryocytes in bone marrow smear are successfully established, which is helpful to improve the application of morphological examination in disease screening, diagnosis and monitoring.

Abstract
Cerebral ischemia reperfusion (I/R) injury easily develops in ischemic stroke, resulting in more serious injury. Ferroptosis is involved in cerebral I/R injury, but the mechanism remains unclear. Prostaglandin E2 (PGE2) is potential to regulate ferroptosis. This study mainly explored the regulation effects of PGE2 on ferroptosis induced by cerebral I/R. We first detected PGE2 levels and ferroptosis status in 11 human brain tissues. Then, we induced a cerebral I/R animal model to examine ferroptosis status in cerebral I/R. We further injected a ferroptosis inhibitor to define the response of the PGE2 pathway to ferroptosis. Finally, we injected PGE2 and pranoprofen to explore the regulation of the cyclooxygenases 2 (COX-2)/PGE2 pathway on ferroptosis in cerebral I/R. We found that PGE2 release was correlated with the levels of reactive oxygen species, malondialdehyde, glutathione peroxidase 4, COX-2, and Spermidine/spermine N1-acetyltransferase 1. Ferroptosis can be induced by cerebral I/R, while inhibition of ferroptosis induced by cerebral I/R can inactivate PGE2 synthases, degrade enzyme, and parts of PGE2 receptors, and reduce cerebral infarct volume. In turn, PGE2 inhibited ferroptosis through the reduction of Fe2+, glutathione oxidation, and lipid peroxidation, while pranoprofen, one of the COX inhibitors, played an opposite role. In conclusion, PGE2 was positively correlated with ferroptosis, inhibition of ferroptosis induced by cerebral I/R can inactivate COX-2/PGE2 pathway, and PGE2 inhibited ferroptosis induced by cerebral I/R, possibly via PGE2 receptor 3 and PGE2 receptor 4. Graphical abstract Inhibition of ferroptosis inactivates the COX-2/PGE2 pathway. Cerebral ischemia reperfusion injury induces the secretion of PGE2. After the inhibition of ferroptosis by Fer-1, the expression of cyclooxygenases (COX-1 and COX-2) decreased, and PGE2 synthases cPGES, mPGES-1, and mPGES-2 were also reduced. At the same time, the PGE2 degradation enzyme 15-PGDH was also reduced. Changes in these enzymes ultimately result in the declination of PGE2. Besides, the expression of PGE2 receptors EP3 and EP4 is also inhibited, indicating that the function they mediate is also impaired. In conclusion, after cerebral ischemia reperfusion injury, the inhibition of ferroptosis inactivates the COX-2/PGE2 pathway.

Abstract
Objective: To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China. Methods: Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women's socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis. Results: A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95%CI: 4.5%-6.1%) and 13.1% (95%CI: 11.3%-14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions: In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.

Abstract
Intracranial aneurysm (IA) is a cerebrovascular disorder in which abnormal dilation of a blood vessel results from weakening of the blood vessel wall. The aneurysm may rupture, leading to subarachnoid hemorrhage with severe outcomes. This study was conducted to identify the genetic factors involved in the etiology of IA. Whole-exome sequencing was performed in three IA-aggregate families to identify candidate variants. Further association studies of candidate variants were performed among sporadic cases and controls. Bioinformatic analysis was used to predict the functions of candidate genes and variants. Twenty variants were identified after whole-exome sequencing, among which eight were selected for replicative association studies. ANK3 c.4403G>A (p.R1468H) was significantly associated with IA (odds ratio 4.77; 95% confidence interval 1.94–11.67; p-value = 0.00019). Amino acid R1468 in ANK3 was predicted to be located in the spectrin-binding domain of ankyrin-G and may regulate the migration of vascular endothelial cells and affect cell–cell junctions. Therefore, the variation p.R1468H may cause weakening of the artery walls, thereby accelerating the formation of IA. Thus, ANK3 is a candidate gene highly related to IA.

Abstract
Objective: To understand influencing factors on the deaths of HIV/AIDS patients receiving antireviral treatment in Butuo county of Liangshan Yi Autonomous Prefecture (Liangshan) from 2010 to 2019, to provide data for drug replacement and sustainable antiviral treatment strategy. Methods: A matched case-control study was used to collect basic and follow-up information on AIDS death patients receiving antiviral treatment in Butuo county of Liangshan from 2010 to 2019. The control group was formed by sampling twice the number of cases. The logistic regression model was used to analyze the risk factors affecting mortality. Results: In 3 355 patients of HIV/AIDS treated with antiviral therapy, 1 179 cases in the death group and 2 176 cases in the control group. Including 81.34% were 30-49 years old, 69.09%males, 99.55% Yi nationality, 91.12% were married or cohabitated, 95.77% had junior high school education or below, and 88.41% peasants. Amultivariate logistic stepwise regression model showed that among the death risk factors, age ≥50 years old was 5.08 times (95%CI:3.05-8.48) that of the 18-29, female was 0.70 times (95%CI: 0.52-0.94) than male, the transmission rate of intravenous drug use was 1.43 times (95%CI: 1.06-1.91) that of heterosexual transmission, CD4+T lymphocyte (CD4) count ≥350 cells/μl before treatment was 0.38 times (95%CI: 0.30-0.48) that of CD4 <200 cells/μl before treatment, the most recent antiviral treatment regimen containing LPV/r was 0.04 times (95%CI: 0.01-0.18) than that of stavudine (d4T) + lamivudine (3TC) + nevirapine (NVP)/efavirenz (EFV) regimen, drug resistance was 3.40 times (95%CI: 2.13-5.42) of non-drug resistance, non-viral load and non-drug resistance test results were 12.98 times (95%CI: 10.28-16.40) of non-drug resistance. Conclusions: Age, gender, transmission route, CD4 before treatment, the latest antiviral treatment program, and drug resistance test after antiviral therapy were the influencing factors of HIV/AIDS death in Butuo county. It is necessary to expand the coverage of viral load and drug resistance test to change the antiviral therapeutic schedule scientifically and carry out publicity and education on the compliance of patients with antiviral treatment and medical staff training in order to reduce the mortality of patients with antiviral treatment.

Abstract
OBJECTIVE Cerebral arteriovenous malformation (AVM) is characterised by an abnormal tangle of arteries and veins, the rupture of which is a significant portion of the morbidity and mortality cases, especially in young populations. However, the exact risk factors and pathophysiologic mechanisms of AVM remain poorly understood. RNF213 variants have been identified as obvious susceptible factors of several cerebrovascular disorders, such as Moyamoya disease and intracranial aneurysms. Thus, this study aimed to determine whether there is an association between RNF213 rare variants and AVM. METHODS The AVM group included 22 patients with AVM. The control group included 1007 samples from the GeneSky in-house database and 208 samples from the 1000 Genome Project of Chinese Han Population. Genomic DNA samples were extracted from the peripheral blood of the AVM patients, and targeted exome sequencing of RNF213 was performed to assess the existence of low-frequency or rare variants. Sanger sequencing was performed to validate the identified variants. Logistic regression analysis was performed to calculate the odds ratios (ORs) and 95 % confidence intervals (CIs) of the candidate variants and risk of AVM. Statistical analyses were performed using SPSS version 21.0. RESULTS The RNF213 c.10997T>C variant (amino acid mutation p.M3666T, NM_001256071) was observed in two AVM patients after filtration. It was significantly associated with AVM in the Chinese population (ORs, 10.30 and 25.08; 95 %; CIs, 1.38-77.10 and 4.34-144.90 compared with 1000 Genome Project of Chinese Han Population and GeneSky in-house database, respectively). CONCLUSION Rare variants of RNF213 are associated with AVM in the Chinese population, suggesting the important role of RNF213 in AVM. Further studies are needed to verify these findings.

Abstract
The traditional classification, diagnosis, and treatment of intracranial aneurysms are based on the characteristics of their vascular lumen. However, in the past few years, some advances in MRI technology with high-resolution imaging can assess the pathology of intracranial vascular walls. Compared with traditional methods of computed tomography angiography, magnetic resonance angiograhpy, and digital subtraction angiography, high resolution magnetic resonance imaging technology can help us to newly understand the disease by directly evaluating the characteristics of vascular wall, such as aneurysm wall thickness, inflammation, enhancement, permeability and hemodynamics. At present, high-resolution magnetic resonance imaging is increasingly used in clinic to assess the rupture risk of intracranial aneurysms, which is of great significance for guiding the diagnosis and treatment of intracranial aneurysms.

Abstract
PURPOSE Intracranial aneurysms (IA) comprise a multifactorial disease with unclear physiological mechanisms. The lysyl oxidase (LOX) family genes (LOX, LOX-like 1-4) plays important roles in extracellular matrix (ECM) reconstruction and has been investigated in terms of susceptibility to IA in a few populations. We aimed to determine whether polymorphisms in LOX family genes are associated with susceptibility to IA in a Chinese population. METHODS This case-control study included 384 patients with IA and 384 healthy individuals without IA (controls). We genotyped 27 single nucleotide polymorphisms (SNPs) of LOX family genes using the Sequenom MassARRAY® platform. These SNPs were adjusted for known risk factors and then, odds ratios (OR) and 95% confidence intervals (CI) were evaluated using binary logistic regression analysis. RESULTS The result showed that LOX rs10519694 was associated with the risk of IA in recessive (OR, 3.88; 95% CI, 1.12-13.47) and additive (OR, 1.56; 95%CI, 1.05-2.34) models. Stratified analyses illustrated that LOX rs10519694 was associated with the risk of single IA in the recessive (OR, 3.95; 95%CI, 1.04-15.11) and additive (OR, 1.64; 95%CI, 1.04-2.56) models. The LOXL2 rs1010156 polymorphism was associated with multiple IA in the dominant model (OR, 1.92; 95%CI, 1.02-3.62). No associations were observed between SNPs of LOXL1, LOXL3, and LOXL4 and risk of IA. CONCLUSION LOX and LOXL2 polymorphisms were associated with risk of single IA and multiple IA in a Chinese population, suggesting potential roles of these genes in IA. The effects of these genes on IA require further investigation.

Abstract
Objective To estimate a stillbirth rate at 24 or more gestational weeks in 2015–2016 and to explore potentially preventable causes in China. Design A multi‐centre cross‐sectional study. Setting Ninety‐six hospitals distributed in 24 (of 34) provinces in China. Population A total of 75 132 births at 24 completed weeks of gestation or more. Methods COX Proportional Hazard Models were performed to examine risk factors for antepartum and intrapartum stillbirths. Population attributable risk percentage was calculated for major risk factors. Correspondence analysis was used to explore region‐specific risk factors for stillbirths. Main outcome measures Stillbirth rate and risk factors for stillbirth. Results A total of 75 132 births including 949 stillbirths were used for the final analysis, giving a weighted stillbirth rate of 13.2 per 1000 births (95% CI 7.9–18.5). Small for gestational age (SGA) and pre‐eclampsia/eclampsia increased antepartum stillbirths by 26.2% and 11.7%, respectively. Fetal anomalies increased antepartum and intrapartum stillbirths by 17.9% and 7.4%, respectively. Overall, 31.4% of all stillbirths were potentially preventable. Advanced maternal age, pre‐pregnant obesity, chronic hypertension and diabetes mellitus were important risk factors in East China; low education and SGA were major risk factors in Northwest, Southwest, Northeast and South China; and pre‐eclampsia/eclampsia and intrapartum complications were significant risk factors in Central China. Conclusions The prevalence of stillbirth was 13.2 per 1000 births in China in 2015–2016. Nearly one‐third of all stillbirths may be preventable. Strategies based on regional characteristics should be considered to reduce further the burden of stillbirths in China. Tweetable abstract The stillbirth rate was 13.2 per 1000 births in China in 2015–2016 and nearly one‐third of all stillbirths may be preventable. The stillbirth rate was 13.2 per 1000 births in China in 2015–2016 and nearly one‐third of all stillbirths may be preventable.

Abstract
PURPOSE Long non-coding RNAs (lncRNAs) have participated in progression of colorectal cancer. This study aims to study the role of RUNX1/RNCR3/miR-1301-3p/AKT1 axis in colorectal cancer. METHODS The cancer tissues were from patients with colorectal cancer. The qRT-PCR was used to determine expression of lncRNA RNCR3, miR-1301-3p, and AKT1. Both dual-luciferase reporter assay and ChIP assay were conducted to investigate the binding sites of RUNX1 on RNCR3 promoter. Western blot was performed to analyze expression of AKT1 protein. Both dual-luciferase reporter assay and RIP assay were performed to detect the interacting sites between RNCR3 and miR-1301-3p. The CCK-8 assay, soft agar assay, transwell assay, and annexin-V-FITC/PI staining were applied to analyze the cell growth, invasion, and apoptosis, respectively. RESULTS The data demonstrated that RNCR3 was elevated in colorectal cancer, and it was negatively correlated with expression of miR-1301-3p which was decreased in cancers. Then, RNCR3 could interact with and suppress miR-1301-3p expression in HCT116 and SW480. Knockdown of RNCR3 or miR-1301-3p overexpression significantly inhibited cell growth, invasion, and increased apoptosis through suppressing expression of Cyclin A1, PCNA, N-cadherin, Bcl-2, and promoting expression of E-cadherin, Bax in vitro and in vivo. RUNX1 was directly bound to RNCR3 promoter to activate RNCR3 expression. Furthermore, overexpression of RNCR3 blocked tumor inhibitory effects of miR-1301-3p on proliferation, colony formation, invasion, and apoptosis in vitro and in vivo. Additionally, RNCR3 and miR-1301-3p synergistically modulated AKT1 expression. CONCLUSION RUNX1-activated upregulation of RNCR3 promoted colorectal cancer progression by sponging miR-1301-3p to elevate AKT1 levels in vitro and in vivo.

Abstract
Dysregulation of retinoblastoma (Rb) signaling pathway have been established as a requirement for glioblastoma (GBM) initiation and progression, which suggests that blockade of CDK4/6-Rb signaling axis for GBM treatment. Palbociclib, a selective inhibitor of the cyclin-dependent kinases CDK4/6, has been applied for breast cancer treatment. However, its efficacy against glioblastoma has not been well clarified. Here, effects of CDK4/6 inhibitors on various kinds of GBM cell lines are investigated and the functional mechanisms are identified. Data showed that cells with diverse PTEN status respond to palbociclib differently. Gain-of-function and loss-of-function studies indicated that PTEN enhanced the sensitivity of GBM cells to palbociclib in vitro and in vivo, which was associated with suppressions of Akt and ERK signaling and independent of Rb signaling inhibition. Hence, our findings support that palbociclib selectively

Abstract
OBJECTIVE Diabetic nephropathy (DN) can cause chronic renal insufficiency and significantly reduce the life quality of patients with diabetes mellitus, and may eventually lead to death. The study investigated the expression of endoplasmic reticulum stress-related factors, which have important roles in the progress of DN and to explore effects of resveratrol on DN and the possible mechanism. MATERIALS AND METHODS Specific pathogen free (SPF) grade healthy male Sprague Dawley (SD) rats were divided into different groups for different treatments. The diabetic rat model was established by intraperitoneal injection of low-dose streptozotocin (STZ) (40 mg/kg). The normal rats and diabetes model rats were divided into four groups including normal control group (N), normal control + resveratrol (N+R), model group (M), and model + resveratrol group (M+R) for different treatments. The changes of renal histology were observed by immunohistochemistry. Glucose oxidase/peroxidase method was used to measure FPG, UP 24 h content was measured by bicinchoninic acid (BCA) assay, BUN, Scr and Cys C content were measured by automatic biochemical analyzer. The expressions of 78 kDa glucose-regulated protein (GRP78), protein kinase RNA-like endoplasmic reticulum kinase (PERK), and activating transcription factor 4 (ATF4) and C/EBP-homologous protein (CHOP) were analyzed by Western blot. RESULTS Resveratrol treatment significantly reduced the fasting blood glucose level, urinary protein level and renal pathological damage. The phosphorylation of PERK in the kidney of rats with diabetes was up-regulated, while resveratrol treatment reduced this change. The expression of p- PERK, GRP78, ATF4, and CHOP was significantly increased in rats with diabetes, while resveratrol treatment can reduce the increased level of those endoplasmic reticulum stress related factors. CONCLUSIONS Resveratrol has a good therapeutic effect on DN in rats without side effect. The mechanism may be related to the regulation of endoplasmic reticulum stress response.

Abstract
The assay was used in HIV/AIDS surveillance sentinel sites to identify recent HIV-1 infection, to estimate HIV-1 incidence and understand the epidemic trends among men who have sex with men during 2011-2015. During 2011-2015, the HIV-1 incidence of men who have sex with men was 5.16%(95%CI: 4.65%-5.66%) in Sichuan Province. According to<Pilot study on classification criteria of AIDS epidemic in China>, a total of 9 cities had been divided into two type of regions: the first type(the proportion of live HIV/AIDS accounts for more than 0.1% of the permanent population, and the number of live HIV/AIDS has reached 500 cases and above) and the second type(the proportion of live HIV/AIDS accounts for 0.03% to 0.100% of the permanent population, and the number of live HIV/AIDS has reached 100-500 cases). During 2011-2015, the HIV-1 incidence of the second type was 4.24% (95%CI: 3.72%-4.76%). The HIV-1 incidence of men who have sex with men was at a high level. The spread of HIV-1 to the second region was possible.

Abstract
BACKGROUND Strangles is a highly contagious respiratory disease of equids caused by the bacterium Streptococcus equi subspecies equi. OBJECTIVES To identify the cause of an outbreak of strangles that occurred on donkey farms within the Shandong Province of China and determine the prevalence of the disease. STUDY DESIGN Cross-sectional. METHODS Samples were taken from clinically affected animals to measure the prevalence of strangles within the population of donkeys at six intensive farms in China and identify the SeM type of isolate recovered from affected animals. Diagnosis was confirmed by bacterial isolation, biochemical tests and PCR. Epidemiological data were analysed using Chi-square test and a Fisher's exact two-sided test. The SeM gene of S. equi isolates recovered from affected animals was determined and compared with the SeM database PubMLST-seM. RESULTS In July and August 2018, an outbreak of strangles occurred on six donkey farms within the Shandong Province of China. The overall prevalence of disease within the different donkey herds was 13.4%. Younger animals were worst affected with 40.3% (83/206) of donkey foals aged under 1 year exhibiting clinical signs compared with 12.5% (191/1525) of donkeys aged one to 2 years and 3.8% (17/442) of donkeys over 2 years of age. Analysis of SeM sequencing data identified that the farms were affected by the same strain of S. equi, SD201807, which contains the novel 136 allele of SeM. MAIN LIMITATIONS Healthy donkeys were not sampled in this study. CONCLUSIONS The number of intensive donkey breeding farms in China has risen recently. The higher numbers of animals that are in closer proximity to one another raise the potential for the transmission of infectious diseases such as strangles. This is the first description of a strangles outbreak among donkey herds in China. The Summary is available in Chinese - see Supporting information.

Abstract
Small cell lung cancer (SCLC) is of a high-grade malignancy with a high metastatic potential and poor clinical prognosis. Unfortunately, SCLC initially exhibits a good response to chemotherapy and radiation therapy, but inevitably, relapses decrease patients' chance of survival. Despite tremendous advances on the development of new chemotherapeutic agents, the prognosis of this disease remains poor. Immunotherapy plays a role in eliciting an anticancer response by modulating the patient's immune response of the tumor. Several studies have demonstrated that abnormal autoimmune regulation has a close relationship with SCLC. Thus, several immunotherapy trials are focused on SCLC treatment, including such approaches as immune checkpoints blockers, tumor vaccine, antigenic targets and adoptive cellular immunotherapy to benefit patients with SCLC. To date, the results from immunotherapy in SCLC have not been promising. For example, tumor vaccines have not been demonstrated to have a significant survival benefit. However, there have been many promising advances with immune checkpoints blockers. This review will provide a general overview of immunotherapy in SCLC. The landmark clinical trials in previous successful immunotherapy studies are summarized here. Finally, the challenges of immunotherapy in SCLC are discussed to facilitate the prediction of possible and valuable strategies for future therapy.

Abstract
OBJECTIVES In our previous research, we have developed a new combination disinfectant, glutaraldehyde-didecyldimethylammonium bromide (GD). It was verified that GD had a strong effect on both Escherichia coli and Staphylococcus aureus. In this work, Candida albicans was selected as an object, and it could be killed by GD. We aimed to investigate the cellular and molecular mechanism of GD effecting on C. albicans. METHODS AND RESULTS The results of sterilization experiment indicated that GD was effective on C. albicans. Flow cytometry and atomic absorption spectrometry were applied to detect cell membrane damage of C. albicans. Luciferase reaction and Bradford method were carried out to detect ATP content and protein quantitation. Transmission electron microscopy was used for intracellular organelles morphological observation. In order to study changes in mitochondrial membrane potential, Rh 123 was used as an indicator. DNA conformation analysis was performed by molecular modelling and circular dichroism. The results indicated that membrane permeability was increased rapidly owing to GD effect, and the leaked K+ and Mg2+ were about 12·1 and 12·4 times those of the control, respectively, at 10 min after GD treatment. Simultaneously, ATP and protein also leaked rapidly out of the cell. Mitochondrial membrane potential was destroyed, succinic dehydrogenase activity was significantly decreased and DNA conformation was changed because of GD action. CONCLUSIONS Glutaraldehyde-didecyldimethylammonium bromide disinfected C. albicans through distorting cell membrane integrity and permeability, disturbing the intracellular homeostasis by intracellular substances leakage, especially K+ , Mg2+ , ATP and protein, causing electrolyte imbalance of mitochondria, changing DNA structure, which finally led to cell death. SIGNIFICANCE AND IMPACT OF THE STUDY This study focused on the cellular and molecular mechanism of GD as a disinfectant against C. albicans. It is important to provide theoretical support to GD against Candida albicans in practical application.

Abstract
OBJECTIVE This study was conducted with the objectives to examine the impacts of inorganic selenium (Se) and different types and levels of organic selenium on the serum and tissues Se status and antioxidant capacity in broiler breeders. METHODS Five hundred and forty 48-wk-old Lingnan Yellow broiler breeders were randomly assigned to 6 dietary treatments, provided same basal diet (0.04 mg/kg of Se) with 0.15 mg/kg, or 0.30 mg/kg of Se from sodium selenite (SS) or from selenium-enriched yeast (SY) or from selenomethionine (SM). The broiler breeders were slaughtered after an 8-wk experiment. RESULTS The results showed that SM was better than SY and SS, 0.30 mg/kg level was better than 0.15 mg/kg level in Se deposition (p<0.05) in serum, liver, kidney, pancreas and muscle; in antioxidant status, organic selenium had better effects than SS in broiler breeders (p<0.05), but SM and SY had a similar result, and 0.15 mg/kg level was better than 0.30 mg/kg (p<0.05). CONCLUSION The results demonstrated the evident advantage of supplementation of broiler breeders with 0.15 mg/kg SM, which improved tissue Se concentrations and antioxidant status, and can be considered as the best selenium source.

Abstract
Objective: Data from the HIV/AIDS surveillance sentinel sites was used to identify the recent HIV-1 infections and to estimate the HIV-1 incidence and epidemic trends among intravenous drug users (IDU), MSM, female sex workers and men attending the sexually transmitted disease clinics in Sichuan province. Methods: Specimens collected from IDUs, MSM, female sex workers and men attending the sexually transmitted disease clinics sentinel sites were confirmed as HIV-1 positive and tested with BED-CEIA. Annual HIV-1 prevalence and incidence rates were calculated and the incidence was adjusted by McNermar method. Results: A total number of 194 223 serum specimens were collected and HIV antibody tested, with 5 297 HIV-1 positive. 4 640 of the positives underwent BED-CEIA, with 749 identified as recent infections. During 2011-2015, HIV-1 incidence rates of the four types of population appeared as 5.16% (95%CI: 4.65-5.66), 0.22% (95%CI:0.16-0.28), 0.57%(95%CI: 0.45-0.69), 7.53% (95%CI: 6.06-9.01) and 0.44% (95%CI: 0.36-0.53) respectively. Significant differences were seen in the HIV-1 incidence rates. Conclusions: The HIV-1 incidence rates of IDUs from other sentinel sites in Sichuan province, female sex workers and men attending the sexually transmitted disease clinics appeared low, showing that the AIDS prevention and control activities worked effectively. However, the HIV-1 incidence of MSM was still at high level and even rising, suggesting that HIV-1 transmission between MSM and IDUs was possible.

Abstract
Genomic studies have established a set of three core-signaling pathways, receptor tyrosine kinase (RTK), p53 and retinoblastoma (Rb) signaling pathways, contributing glioblastoma (GBM) and revealed that dysregulation of at least two pathways is required for GBM progression. In the present study, we investigate efficacy of combination of palbociclib, cyclin-dependent kinase 4/6 (CDK4/6) inhibitor, and erlotinib, epidermal growth factor receptor (EGFR) inhibitor in GBM cell systems with different p53 status. Cell proliferation and colony formation assays showed that the combination treatment synergistically suppressed GBM cell proliferation. LN229 cells with mutant p53 and wild-type PTEN were more sensitive to the combination treatment. Further studies indicated that the synergetic anti-GBM effects were due to cell apoptosis induction and cell cycle arrest at G1 phase. Signaling examination indicated that levels of p-Rb and p-4E-BP1 significantly decreased by the combination treatment; however, Akt and MAPK signaling were differentially suppressed among the three GBM cell lines. Hence, our data demonstrate that palbociclib and erlotinib exert synergistic anti-GBM activity, providing pre-clinical evidence and a proof-ofconcept that usage of the combination of EGFR and CDK4/6 inhibitors for GBM treatment.

Abstract
Objective: To investigate the potential role of Bit1 in the pathogenesis of pancreatic ductal cancer cells(PDAC) and its potential clinical application value. Methods: Real-time PCR and Western blot were employed to detect the expression of Bit1 in six pancreatic cancer cells, then the tool cells were selected to further study the function of Bit1.PolyHEMA was used to monitor the suspended cell culture condition in vitro.The invasion and migration abilities of pancreatic cancer cells were detected through Transwell assay. Western blot and confocal assay were used to explore the potential mechanism of Bit1 in the process of metastasis.The expression of Bit1 was detected through tissue microarray, the potential relationship between Bit1 and other clinical factors were analyzed. Results: The results of real-time PCR and Western blot indicated that the expression of Bit1 was highest in the PANC1 cells and lowest in the Mia paca2 cells (gene: 3.13±0.40 vs. 1.00±0.35, protein: 1.77±1.00 vs. 0.23±0.45). The shBit1 PANC1 and Bit1-OE(over expression) Mia paca2 cells were successfully constructed.Bit1 over expression could promote the anoikis rate of Mia paca2 cells, and Bit knockdown could inhibit the anoikis incidence.Bit1 over expression suppressed the motility and invasion of Mia paca2 cells, but Bit1 knockdown could accelerate the migration and invasion ability of PANC1 cells.Bit1 could potentially affect pancreatic cancer cells' malignant behaviors through epithelial-mesenchymal transition process.Bit1 expression was significantly associated with pancreatic cancer's neural invasion (P<0.05). Conclusions: Bit1 could affect the anoikis incidence of pancreatic cancer, Bit1 negatively affect the migration and invasion abilities of PDAC, the EMT process was potentially involved in the whole modulation process.Bit1 expression is associated with neural invasion in pancreatic cancer patients.

Abstract
Abstract
In this study thermoplastic polyurethane (TPUs) nanocomposites incorporating carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) were prepared via melt blending and compression molding and CNT dispersion was optimized by using non-covalent surface modification (surfactant). Filler dispersion was further improved by combining two fillers with different geometric shape and aspect ratio in hybrid filler nanocomposites. Synergistic effects were observed in the TPU-GNP-CNT hybrid composites, especially when combining GNP and CNT at a ratio of 6 : 4, showing higher tensile modulus and strength with respect to the systems incorporating individual CNTs and GNPs at the same overall filler concentration. This improvement was attributed to the interaction between CNTs and GNPs limiting GNP aggregation and bridging adjacent graphene platelets thus forming a more efficient network. Hybrid systems also exhibited improved creep resistance and recovery ability. Morphological analysis carried out by scanning electron microscopy (SEM) indicated that the hybrid nanocomposite presented slightly smaller and more homogeneous filler aggregates. The well-dispersed nanofillers also favored higher phase separation in TPU, as indicated by atomic force microscopy (AFM), resulting in a better microstructure able to enhance the load transfer and maximize the mechanical and viscoelastic properties.

Abstract
OBJECTIVE To explore the influence of patatin-like phospholipase domain-containing protein 3 (PNPLA3) on palmitic acid (PA)-induced hepatocyte apoptosis and its mechanism. METHODS Human hepatocarcinoma cell line HepG2 cells were transfected with PNPLA3(WT)-pcDNA3.1 (PNPLA3(WT) group) and PNPLA3(I148M)-pcDNA3.1 (PNPLA3(I148M) group) plasmids respectively to overexpress wild type or mutant type PNPLA3, and cells transfected with empty vector pcDNA3.1 (NC group) were set as control group.After 24 h PA incubation, Oil red staining was used to determine lipid deposition, and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) was used to measure apoptosis.Western blot was used to detect the protein level of endoplasmic reticulum (ER) stress and associated apoptosis.Enzyme-linked immunosorbent assay (ELISA) was used to test lysolecithin (LPC) levels in the cellular supernatant. RESULTS After 24 h PA incubation, there was no significant difference in lipid deposition among three groups.Compared to NC group, the cell apoptosis rates of PNPLA3(WT) and PNPLA3(I148M) groups were increased by 2 times and 3 times respectively.The levels of ER stress PRKR-like endoplasmic reticulum kinase (PERK) pathway associated proteins, immunoglobulin-binding protein (BIP), p-PERK, p-eIF2α, and ER stress associated apoptosis pathway proteins, CCAAT/enhancer binding homologous protein (CHOP), p53 upregulated modulator of apoptosis (PUMA), Bax, caspase-3 were higher, and were more significant in PNPLA3(I148M) group.The LPC level in the supernatant of PNPLA3(WT) and PNPLA3(I148M) groups were about 5 times and 1.5 times of NC group respectively after PA incubation. CONCLUSION PNPLA3 may be involved in palmitic acid-induced apoptosis mediated by hepatocyte ER stress through regulating LPC metabolism.

Abstract
Objective Road traffic injuries are caused by many different factors. This study aimed to analyse road user type information in Chongqing, China in order to develop prevention strategies as well as treatment protocols. Methods Data from road traffic crashes from Chongqing, China were collected prospectively over a seven-year period (2000 to 2006). The data included the road user type, description of the injury, mortality and Abbreviated Injury Scale. Prevalence and cross-tabulations were included in the analysis. Results Forty-nine percent of deaths were pedestrians and 27.84% of deaths were drivers. Head injuries (26.49%) of pedestrians were higher than those of drivers and passengers. Thoracic injuries (22.78%) and spinal injuries (4.44%) of injured passengers were higher than those of drivers and pedestrians. There were significant differences in road user types in both injury severity and injury regions. Conclusions The distribution of road traffic injuries in Chongqing, China is different from that in developed countries and other developing countries. In managing traffic injuries, it is necessary to examine other regions besides the head according to the road user type, such as facial injuries of drivers and passengers, and chest and spinal injuries of passengers.

Abstract
OBJECTIVE To investigate the in vitro and in vivo anticancer efficacy of the immunotoxin DTAT and DTATEGF against globlastoma multiforme. METHODS The in vitro cytotoxicity of DTAT and DTATEGF was measured using MTT assay. In vivo studies were performed in which 18 nude mice were randomly divided into 3 groups and the glioma xenograft intracranial mouse model was constructed with U87-luc cell line of human glioma. Then 1 μg of DTAT, or DTATEGF, or a control protein Bickel3 was delivered intracranially by convection-enhanced delivery (CED) via an osmotic minipump. The brain tumor fluorescence signal intensity was investigated by bioluminescent imaging (BLI). Microvessel density (MVD) was measured by immunchistochemistry SABC method in each group. RESULTS In vitro DTAT and DTATEGF were found highly potent against U87-luc cell line, with IC(50) <0.01 nmol/L and IC(50)<1 nmol/L, respectively. In vivo BLI monitoring of the control group showed progressively increasing luminescence, while in the two treatment groups, luminescence was reduced on day 8, and increased slowly (P<0.05). The MVD of DTAT (31.6±5.2)/mm(2) and DTATEGF (25.1±6.5)/mm(2) groups had significant difference with that of the control group (51.3±7.4) /mm(2) (P<0.01). CONCLUSION Both DTAT and DTATEGF have potential in clinical application against globlastoma multiforme because of their ability to target the tumor cells and neovasculature simultaneously.

Abstract
In this paper, 3D particle focusing in a straight channel with asymmetrical expansion-contraction cavity arrays (ECCA channel) is achieved by exploiting the dean-flow-coupled elasto-inertial effects. First, the mechanism of particle focusing in both Newtonian and non-Newtonian fluids was introduced. Then particle focusing was demonstrated experimentally in this channel with Newtonian and non-Newtonian fluids using three different sized particles (3.2 μm, 4.8 μm, and 13 μm), respectively. Also, the effects of dean flow (or secondary flow) induced by expansion-contraction cavity arrays were highlighted by comparing the particle distributions in a single straight rectangular channel with that in the ECCA channel. Finally, the influences of flow rates and distances from the inlet on focusing performance in the ECCA channel were studied. The results show that in the ECCA channel particles are focused on the cavity side in Newtonian fluid due to the synthesis effects of inertial and dean-drag force, whereas the particles are focused on the opposite cavity side in non-Newtonian fluid due to the addition of viscoelastic force. Compared with the focusing performance in Newtonian fluid, the particles are more easily and better focused in non-Newtonian fluid. Besides, the Dean flow in visco-elastic fluid in the ECCA channel improves the particle focusing performance compared with that in a straight channel. A further advantage is three-dimensional (3D) particle focusing that in non-Newtonian fluid is realized according to the lateral side view of the channel while only two-dimensional (2D) particle focusing can be achieved in Newtonian fluid. Conclusively, this novel Dean-flow-coupled elasto-inertial microfluidic device could offer a continuous, sheathless, and high throughput (>10 000 s(-1)) 3D focusing performance, which may be valuable in various applications from high speed flow cytometry to cell counting, sorting, and analysis.
