Abstract
During summer 2022, a cluster of Madagascar periwinkle plants with white and mauve flowers were observed with foliar mild yellow mosaic symptoms on a private property in Harlingen, Cameron County, Texas. The symptoms were reproduced on mechanically inoculated periwinkle and Nicotiana benthamiana plants. Virions of 776 to 849 nm in length and 11.7 to 14.8 nm in width were observed in transmission electron microscopy of leaf dip preparations made from symptomatic periwinkle leaves. Highthroughput sequencing (HTS) analysis of total RNA extracts from symptomatic leaves revealed the occurrence of two highly divergent variants of a novel Potyvirus species as the only virus-like sequences present in the sample. The complete genomes of both variants were independently amplified via RT-PCR, cloned, and Sanger sequenced. The 5' and 3' of the genomes were acquired using RACE methodology. The assembled virus genomes were 9,936 and 9,944 nucleotides (nt) long and they shared 99.9-100% identities with the respective HTS-derived genomes. Each genome encoded hypothetical polyprotein of 3,171 amino acids (aa) (362.6 kDa) and 3,173 aa (362.7 kDa), respectively, and they shared 77.3%/84.4% nt/aa polyproteins identities, indicating that they represent highly divergent variants of the same Potyvirus species. Both genomes also shared below species threshold polyprotein identity levels with the most closely phylogenetically related known potyviruses thus indicating that they belong to a novel species. The name periwinkle mild yellow mosaic virus (PwMYMV) is given to the potyvirus with complete genomes of 9,936 nt for variant 1 (PwMYMV-1) and 9,944 nt for variant 2 (PwMYMV-2). We propose that PwMYMV be assigned into the genus Potyvirus (family Potyviridae).

Abstract
Rubus yellow net virus (RYNV) belongs to genus Badnavirus. Badnaviruses are found in plants as endogenous, inactive or activatable sequences, and/or in episomal (infectious and active) forms. To assess the state of RYNV in Rubus germplasm, we sequenced the genomes of various cultivars and mined eight raspberry whole genome datasets. Bioinformatics analysis revealed the presence of a diverse array of endogenous RYNV (endoRYNV) sequences that differ significantly in their structure; some lineages have nearly complete, yet non-functional genomes whereas others have rudimentary, short sequence fragments. We developed assays to genotype the main lineages as well as the only known episomal lineage present in the United States. This study discloses the widespread presence of endoRYNVs in commercial raspberries, likely because breeding efforts have focused on a limited pool of germplasm that harbored endoRYNVs.

Abstract
OBJECTIVES The comprehensive description of hearing loss in China and the shifting pattern remain unclear. We conducted the study to estimate the burden of hearing loss in China and project the trends from 2020 to 2034. STUDY DESIGN AND METHOD Data on the disease burden of hearing loss were extracted from the Global Burden of Disease Study 2019. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of hearing loss burden were made until 2034 using Bayesian age-period-cohort analysis. RESULTS In China, prevalent cases of hearing loss increased from 224.4 million in 1990 to 426.5 million in 2019, representing an increase of 90.1 %. The age-standardized prevalence rate of hearing loss ranged from 22,592.8/100,000 in 1990-22,612.4/100,000 in 2019, with an EAPC of 0.003 %, representing a stable trend. Of the category of hearing loss, mild hearing loss accounted for the highest proportion, with 331.4 million people. More than 95 million people had moderate-to-complete hearing loss. Moreover, hearing loss was mostly attributable to age-related and other factors for adults and otitis media for children younger than 10 years. Based on the projection results, there will be 561 million people (40.1 % of the total population) have hearing loss by 2034. CONCLUSIONS The prevalent cases of hearing loss in China substantially increased over the last 30 years. Over two in five Chinese people will have hearing loss by 2034, thus suggesting more solutions should be established to reduce the burden of hearing loss.

Abstract
OBJECTIVES Carotid intima-media thickness (CIMT) is a noninvasive marker of atherosclerosis, a typical pathologic process underlying cardiovascular diseases (CVDs). It is essential to explore the relationships between weight loss and the reduction of CIMT. STUDY DESIGN This was an updated systematic review and meta-analysis. METHODS A systematic literature search was conducted to collect relevant clinical trials. The pooled results of meta-analyses were assessed by weighted mean difference (WMD) and the corresponding 95 % confidence interval (95% CI). RESULTS Thirty-three articles involving 2273 participants were collected in this meta-analysis. Among all participants with obesity, the pooled mean of weight loss was -23.26 kg (95% CI: -27.71 to -18.81), and the pooled mean change of CIMT was -0.06 mm (95% CI: -0.08 to -0.04). Compared with Non-surgical interventions, Surgical ones could lead to much higher weight loss (Pbetween groups < 0.001). A more significant CIMT reduction was identified among Surgical intervention patients than among Non-surgical intervention participants (Pbetween groups < 0.001). CONCLUSIONS Effective interventions, especially Surgical interventions, could reduce the weight of patients with obesity, followed by the decline of CIMT, which might further disturb atherosclerosis progression and lower CVD risk.

Abstract
Citrus yellow vein clearing virus (CYVCV) is a previously reported citrus virus from Asia with widespread distribution in China. In 2022 the California Department of Food and Agriculture (CDFA) conducted a multi-pest citrus survey targeting multiple citrus pathogens including CYVCV. In March 2022, a lemon tree with symptoms of vein clearing, chlorosis and mottling in a private garden in the city of Tulare, California tested positive for CYVCV, which triggered an intensive survey in the surrounding areas. A total of 3,019 plant samples, including citrus and non-citrus species, were collected, and tested for CYVCV using conventional RT-PCR, RT-qPCR, and Sanger sequencing. Five hundred eighty-six citrus trees tested positive for CYVCV, including eight citrus species not previously recorded infected under field conditions. Comparative genomic studies were conducted using seventeen complete viral genomes. Sequence analysis revealed two major phylogenetic groups. Known Asian isolates and five California isolates from this study comprised the first group, whereas all other CYVCV isolates from California formed a second group, distinct from all worldwide isolates. Overall, CYVCV population shows rapid expansion and high differentiation indicating a population bottleneck typical of a recent introduction into a new geographic area. .

Abstract
Objective: To understand the sexually active status among community-based older adults aged ≥50 years in Tianjin, China, and to explore the potential correlates. Methods: A cross-sectional survey using multistage sampling among community-based older adults aged ≥50 was conducted between June 2020 and December 2022. The estimated sample size was 735. The survey collected questionnaire information through face-to-face interviews with investigators, including sociodemographic, health, and sexual lifestyle characteristics. The multivariable logistic regression model was used to assess correlates of sexually active status. Results: A total of 776 study participants (510 males and 266 females) were included, whose major age distribution was 50-59 years (45.9%). The overall sexual activity prevalence of the participants was 45.6%. Older age (60-69: aOR=0.67, 95%CI: 0.45-0.99; ≥70: aOR=0.12, 95%CI: 0.07-0.21), being male (aOR=1.93, 95%CI: 1.32-2.82), living in urban area (aOR=0.18, 95%CI: 0.12-0.28), living with spouse/married (aOR=2.80, 95%CI: 1.41-5.58), living alone (aOR=0.51, 95%CI: 0.27-0.96), having difficulty climbing stairs or walking (aOR=0.55, 95%CI: 0.31-0.97), having chronic diseases (one chronic disease: aOR=0.55, 95%CI: 0.36-0.85; two or more chronic diseases: aOR=0.53, 95%CI: 0.33-0.84) were associated with sexually active status among older adults. Conclusions: Many community-based older adults remained sexually active. There was an association between physical health and sexually active status among community-based older adults. Incorporating sexual health services into healthcare services for community-based older adults could be advocated, with a concurrent emphasis on enhancing the awareness and competence of providing sexual health services among community-based healthcare workers.

Abstract
Objective: To understand the current status of condom use and its correlates among community-based older adults in Chongqing, China. Methods: Cross-sectional study based on a multistage sampling method was conducted in Chongqing from June 2020 to December 2022. The estimated sample size was 735. Through face-to-face interviews, the investigators collected the sociodemographic characteristics, sexual behavior characteristics, awareness of AIDS prevention knowledge, etc. A multivariable logistic regression model was used to explore the correlates of condom use during the last sexual behavior among the participants. Results: A total of 761 participants were included in this study, with 476 males and 285 females, whose average age was (63.8±8.2) years old, mainly in the age group of 60-69 years (44.5%). Among the participants, the rate of condom use during the last sexual behavior was 9.7%. The multivariable logistic regression analysis indicated that correlates of condom use during the last sexual behavior included urban household registration (aOR=2.34, 95%CI: 1.12-4.89), monthly income of 1 000-4 999 Yuan, and 5 000 Yuan and above (aOR=4.49, 95%CI: 1.31-15.41; aOR=16.33, 95%CI: 4.30-62.00), self-assessed sexual behavior risk as very risky/relatively risky (aOR=3.97, 95%CI: 1.40-11.31), awareness of AIDS prevention knowledge (aOR=0.36, 95%CI: 0.21-0.62). Conclusions: The rate of condom use among community-based older adults in Chongqing is low. Comprehensive intervention measures should be taken in combination with the characteristics and needs of community-based older adults to improve awareness of AIDS prevention knowledge and perception of AIDS risk and promote condom use among this population.

Abstract
As a prevalent neurodevelopmental disease, attention-deficit hyperactivity disorder (ADHD) impairs the learning and memory capacity, and so far, there has been no available treatment option for long-term efficacy. Alterations in gene regulation and synapse-related proteins influence learning and memory capacity; nevertheless, the regulatory mechanism of synapse-related protein synthesis is still unclear in ADHD. LncRNAs have been found participating in regulating genes in multiple disorders. For instance, lncRNA Metastasis Associated Lung Adenocarcinoma Transcript 1 (MALAT1) has an essential regulatory function in numerous psychiatric diseases. However, how MALAT1 influences synapse-related protein synthesis in ADHD remains largely unknown. Here, our study found that MALAT1 decreased in the hippocampus tissue of spontaneously hypertensive rats (SHRs) compared to the standard controls, Wistar Kyoto (WKY) rats. Subsequent experiments revealed that MALAT1 enhanced the expression of neurexin 1 (NRXN1), which promoted the synapse-related genes (SYN1, PSD95, and GAP43) expression. Then, the bioinformatic analyses predicted that miR-141-3p and miR-200a-3p, microRNAs belonging to miR-200 family and sharing same seed sequence, could interact with MALAT1 and NRXN1 mRNA, which were further confirmed by luciferase report assays. Finally, rescue experiments indicated that MALAT1 influenced the expression of NRXN1 by sponging miR-141-3p/200a-3p. All data verified our hypothesis that MALAT1 regulated synapse-related proteins (SYN1, PSD95, and GAP43) through the MALAT1-miR-141-3p/200a-3p-NRXN1 axis in ADHD. Our research underscored a novel role of MALAT1 in the pathogenesis of impaired learning and memory capacity in ADHD and may shed more light on developing diagnostic biomarkers and more effective therapeutic interventions for individuals with ADHD.

Abstract
Objective: To evaluate the effectiveness of hepatitis B prevention and control in Tibet Autonomous Region by comparative analysis of the results of seroepidemiological surveys of hepatitis B in 2014 and 2020. Methods: The required sample size was calculated based on the estimated HBsAg positivity rates of permanent residents aged 1-4, 5-14, 15-29, and 30-69 years. A total of 7 163 people and 4 802 people were required in 2014 and 2020, respectively. The subjects were selected by stratified multistage cluster random sampling method, using questionnaires to obtain basic information, and 5 ml of venous blood was collected from each subject to detect HBsAg, anti-HBs, and anti-HBc, and rechecked the HBsAg positive samples. SPSS 22.0 software was used to analyze the survey results, calculate the positive rate and 95% confidence interval. Results: A total of 7 069 people were investigated in 2014 and 4 913 people in 2020. In 2020, the positive rate of HBsAg, anti-HBs, and anti-HBc was 9.20% (452/4 913), 37.11% (1 823/4 913), and 32.75% (1 609/4 913), respectively, and decreased by 22.95%, 15.54%, and 1.92% as compared with the rate in 2014. The positive rate of HBsAg of people aged 1-, 5-, 15- and 30-69 years in 2020 was 2.23% (8/358), 2.85% (20/701), 6.86% (69/1 006) and 12.46%(355/2 848), respectively, decreased by 61.82%, 62.75%, 54.81% and 24.21% as compared with the rate in 2014. The positive rate of anti-HBs of people aged 1-4 years was 52.79% (189/358), 10.30% increased compared with 2014; for people aged 5-, 15-, and 30-69 years was 32.67% (229/701), 37.67% (379/1 006) and 36.03%(1 026/2 848), respectively, decreased by 20.84%, 14.13% and 16.52% as compared with the rate in 2014. The positive rate of anti-HBc of people aged 1-, 5-, 15-, 30-69 years was 4.19% (15/358), 6.42%(45/701), 21.07% (212/1 006), and 46.95% (1 337/2 848), respectively, decreased by 59.63%, 58.93%, 50.49%, and 12.10% as compared with the rate in 2014. Conclusions: The prevention and control of hepatitis B in Tibet have made partial achievements. The prevalence of HBsAg among people aged 1-69 years in 2020 had declined compared with 2014, but it is still at a high epidemic level. People have a high risk of HBV infection for a low level of anti-HBs. It is necessary to strengthen the vaccination of hepatitis B further and effectively implement the strategy of blocking mothers and children of the hepatitis B virus.

Abstract
As a neglected tropical disease defined by the World Health Organization (WHO), echinococcosis causes a huge public health burden. Understanding the disease burden due to echinococcosis facilitates the progress towards elimination of the disease. This review analyzes the advances in disease and economic burdens of echinococcosis, describes the status quo disease burden due to echinococcosis in different areas of the world, compares the difference between international and national studies on disease and economic burdens of echinococcosis, and discusses the shortcomings of the current international and national studies on disease burden of echinococcosis. Currently, the studies on disease burden of echinococcosis suffer from problems of few field survey data and lack of authoritative disability weights for echinococcosis, while the studies on economic burden of echinococcosis suffer from problems of lack of comprehensive study populations and indicators.

Abstract
Objective: To investigate the mechanism of S100A7 inducing the migration and invasion in cervical cancers. Methods: Tissue samples of 5 cases of cervical squamous cell carcinoma and 3 cases of adenocarcinoma were collected from May 2007 to December 2007 in the Department of Gynecology of the Affiliated Hospital of Qingdao University. Immunohistochemistry was performed to evaluate the expression of S100A7 in cervical carcinoma tissues. S100A7-overexpressing HeLa and C33A cells were established with lentiviral systems as the experimental group. Immunofluorescence assay was performed to observe the cell morphology. Transwell assay was taken to detect the effect of S100A7-overexpression on the migration and invasion of cervical cancer cells. Reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) was used to examine the mRNA expressions of E-cadherin, N-cadherin, vimentin and fibronectin. The expression of extracellular S100A7 in conditioned medium of cervical cancer cell was detected by western blot. Conditioned medium was added into Transwell lower compartment to detect cell motility. Exosomes were isolated and extracted from the culture supernatant of cervical cancer cell, the expressions of S100A7, CD81 and TSG101 were detected by western blot. Transwell assay was taken to detect the effect of exosomes on the migration and invasion of cervical cancer cells. Results: S100A7 expression was positively expressed in cervical squamous carcinoma and negative expression in adenocarcinoma. Stable S100A7-overexpressing HeLa and C33A cells were successfully constructed. C33A cells in the experimental group were spindle shaped while those in the control group tended to be polygonal epithelioid cells. The number of S100A7-overexpressed HeLa cells passing through the Transwell membrane assay was increased significantly in migration and invasion assay (152.00±39.22 vs 105.13±15.75, P<0.05; 115.38±34.57 vs 79.50±13.68, P<0.05). RT-qPCR indicated that the mRNA expressions of E-cadherin in S100A7-overexpressed HeLa and C33A cells decreased (P<0.05) while the mRNA expressions of N-cadherin and fibronectin in HeLa cells and fibronectin in C33A cells increased (P<0.05). Western blot showed that extracellular S100A7 was detected in culture supernatant of cervical cancer cells. HeLa cells of the experimental group passing through transwell membrane in migration and invasion assays were increased significantly (192.60±24.41 vs 98.80±47.24, P<0.05; 105.40±27.38 vs 84.50±13.51, P<0.05) when the conditional medium was added into the lower compartment of Transwell. Exosomes from C33A cell culture supernatant were extracted successfully, and S100A7 expression was positive. The number of transmembrane C33A cells incubated with exosomes extracted from cells of the experimental group was increased significantly (251.00±49.82 vs 143.00±30.85, P<0.05; 524.60±52.74 vs 389.00±63.23, P<0.05). Conclusion: S100A7 may promote the migration and invasion of cervical cancer cells by epithelial-mesenchymal transition and exosome secretion.

Abstract
Between 2010 and 2018, sunflower plants exhibiting virus-like symptoms, including stunting, mottling, and chlorotic ringspots on leaves, were observed from commercial fields and research plots from four sites within three distinct counties of western Nebraska (Box Butte, Kimball, and Scotts Bluff). Near identical symptoms from field samples were reproduced on seedlings mechanically in the greenhouse on multiple occasions, confirming the presence of a sap-transmissible virus from each site. Symptomatic greenhouse-inoculated plants from the 2010 and 2011 Box Butte samples tested negative for sunflower mosaic virus (SuMV), sunflower chlorotic mottle virus (SuCMoV), and all potyviruses in general by ELISA and RT-PCR. Similar viral-like symptoms were later observed on plants in a commercial sunflower field in Kimball County in 2014, and again from volunteers in research plots in Scotts Bluff County in 2018. Samples from both of these years were again successfully reproduced on seedlings in the greenhouse as before following mechanical transmissions. Symptom expression for all years began 12 to 14 days after inoculation as mild yellow spots followed by the formation of chlorotic ringspots from the mottled pattern. The culture from 2014 tested negatively for three groups of nepoviruses via RT-PCR, ruling this group out. However, transmission electron microscopy assays of greenhouse-infected plants from both 2014 and 2018 revealed the presence of distinct, polyhedral virus particles. With the use of high throughput sequencing and RT-PCR, it was confirmed that the infections from both years were caused by a new virus in the tombusvirus genus and was proposed to be called Sunflower ring spot mottle virus (SuRSMV). Although the major objective of this project was to identify the causal agent of the disease, it became evident that the diagnostic journey itself, with all the barriers encountered on the 10-year trek, was actually more important and impactful than identification.

Abstract
Objective: To investigate the effect of celastrol (CEL) on autophagy and endoplasmic reticulum stress-mediated apoptosis in a mouse model of nonalcoholic fatty liver disease (NAFLD). Methods: Eighteen male C57BL/6J mice were randomly divided into normal control (NC, n=6), high-fat diet (HFD, n=6) and celastrol group (HFD+CEL, n=6). The normal control group was fed with regular diet, and the high-fat diet and celastrol group were fed with high-fat diet for 12 weeks. After successful modeling, celastrol group were injected with 100 μg⋅kg-1⋅d-1 celastrol intraperitoneally for 4 weeks, and NC and HFD group were injected intraperitoneally with the same doses of normal saline. Serum concentrations of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were measured in mouse after 4-weeks of intervention. HE and Oil Red O staining were used to observe the pathomorphological changes and lipid droplet deposition in mouse liver, and the findings were scored according to NAFLD activity score (NAS). Western blot was used to detect the expression levels of liver microtubule associated protein 1 light chain 3 (LC3), P62, glucose-regulated protein 78 (GRP78), protein kinase R-like endoplasmic reticulum kinase (PERK), phosphorylated PERK (p-PERK), activated transcription factor 4 (ATF4), C/EBP homologous protein (CHOP), cleaved Caspase-3(cleaved caspase-3), B-cell lymphoma-2 (Bcl-2) and Bcl-2 related X protein (Bax).TUNEL staining was used to observe the apoptosis of hepatocytes. One-way analysis of variance was used for the intergroup comparison. Results: Serum levels of ALT (68.71±8.57) U/L, AST (209.63±28.64) U/L, TG (0.97±0.14) mmol/L, TC (4.12±0.64) mmol/L, and LDL -C (0.40±0.06) mmol/L were lower in celastrol group mouse than HFD group [(110.19±10.79) U/L, (399.72±73.47) U/L, (1.44±0.13) mmol/L, (5.65±0.54) mmol /L, (0.61±0.07) mmol/L] (P<0.05); while the serum HDL-C level (1.29±0.17) mmol/L was higher in celastrol than HFD group (0.72±0.13) mmol/L (P<0.05). HE and Oil Red O staining showed that lipid deposition and intralobular inflammation were apparent in the liver tissue of HFD group mouse, and the NAS score was significantly increased, while the hepatocyte steatosis and intralobular inflammation were alleviated after celastrol intervention, and the NAS score was decreased significantly (P<0.05). Compared with HFD group, the ratio of LC3II/I was significantly increased in the liver of celastrol group mouse, and the P62 was significantly decreased (P<0.05). Meanwhile, the expression level of GRP78, p-PERK/PERK , ATF4, and CHOP was significantly lower in celastrol than HFD group (P<0.05). In addition, the expressions of cleaved caspase-3 and Bax were significantly lower in celastrol than HFD group, and the expression of Bcl-2 was significantly increased (P<0.05). At the same time, the apoptosis rate of hepatocytes was also significantly lower in celastrol than HFD group (P<0.05). Conclusion: Celastrol can effectively alleviate the lipid deposition, protect hepatocytes and delay the progression of non-alcoholic fatty liver disease in mouse liver with non-alcoholic fatty liver disease. In addition, its mechanism of action may be related to the induction of autophagy, inhibition of endoplasmic reticulum stress PERK/ATF4/CHOP pathway and its mediated apoptosis.

Abstract
The last two decades have seen exponential growth in the international movement of seeds for annual food crops, from a gross U.S. import value of $349 million in 1999 to $1.05 billion in 2019. This has led to the proportionate growth of seedborne pathogens dispersed with seed stocks. One such viral pathogen is cucumber green mottle mosaic virus (CGMMV), a tobamovirus that infects cucurbit crops such as melon, watermelon, cucumber, pumpkin, and squash. The first CGMMV introduction to California occurred in 2013, with subsequent annual outbreaks or detections since then. Here, we describe the use of next-generation sequencing to characterize the full genomes of 25 CGMMV isolates collected between 2013 and 2020 in California, either from CGMMV field detections or seed lots identified as CGMMV positive. We sequenced an additional 31 CGMMV isolates collected in Europe, Israel, and southeast Asia that were provided by industry collaborators. We also performed an in silico nucleotide database search in GenBank for full genome CGMMV sequences to include in all in silico analyses. Based on conserved regions within the coat protein gene, we then developed a quantitative reverse-transcription PCR assay for the sensitive and specific detection of CGMMV in seed and plant samples. Finally, based on our sequence and phylogenetic analysis, our data support that CGMMV has been introduced multiple times into California.

Abstract
Objective: To observe the dynamic changes of brainstem locus coeruleus (LC) damage in Parkinson' s disease (PD) -like mice by paraquat (PQ) . Methods: In October 2019, 36 male C57BL/6 mice were randomly divided into the exposure group and the control group, with 18 mice in each group. The mice in the exposure group were given intraperitoneal injection of 15 mg/kg PQ, and the mice in the control group were given intraperitoneal injection of 0.9% saline, twice a week for 8 weeks. Neurobehavioral changes (pole climbing test, swimming test, open field test, tail hanging test, high plus maze test and water maze test) were observed at 4 weeks, 6 weeks and 8 weeks, respectively, and the changes of motor ability, emotion and cognitive function were evaluated. The brain tissue of mice were taken and stained with Hematoxylin-Eosin (HE) to observe the pathological changes of LC. Nissl staining was used to detect the changes of neuronal Nissl bodies in LC. Immunohistochemistry (IHC) staining was used to detect the expression of neuron nuclear antigen (NeuN) , dopamine (DA) neurons and norepinephrine (NE) neuron markers tyrosine hydroxylase (TH) , α-synuclein (α-syn) in substantia nigra (SN) and LC. The expression levels of NeuN, TH and α-syn in the midbrain and brainstem were detected by Western blotting. TUNEL staining was used to detect neuronal apoptosis in LC. Results: Compared with the 4th week of PQ exposure group, the time of pole climbing and swimming immobility were gradually increased, the ratio of open arm residence time of high plus maze test and the number of times of the platform and the residence time of platform quadrant in water maze test were gradually decreased (P<0.05) in the exposure group with the progress of exposure time. The results of HE and Nissl staining showed that the neurons in LC gradually arranged loosely, the nucleus were deeply stained, the cytoplasm was pyknosis, and the number of Nissl bodies gradually decreased (P<0.05) in the exposure group with the progress of exposure time. IHC results showed that the number of NeuN and TH positive cells in SN and LC of mice were gradually decreased, and the positive expression of α-syn was gradually increased (P<0.05) in the exposure group with the progress of exposure time. Western blotting results showed that the expression levels of NeuN and TH in the midbrain and brainstem were gradually decreased, and the expression level of α-syn was gradually increased (P<0.05) in the exposure group with the progress of exposure time. TUNEL staining showed that the apoptosis rates of neurons in LC were gradually increased (P<0.05) in the exposure group with the progress of exposure time. Conclusion: PQ induces progressive damage in the LC area of PD-like mice, which may be caused by the abnormal accumulation of pathological α-syn in the LC area.

Abstract
OBJECTIVE To evaluate the molluscicidal effect of 25% wettable powder of pyriclobenzuron sulphate (WPPS) against Oncomelania snails in hilly schistosomiasis-endemic regions and test its toxicity to fish. METHODS In October 2020, a snail-infested setting which had been cleared was selected in Nanjian County, Yunnan Province and divided into several blocks, and the natural snail mortality was estimated. 25% WPPS was prepared into solutions at concentrations of 1 and 2 g/L, and 25% wettable powder of niclosamide ethanolamine salt (WPNES) was prepared into solutions at a concentration of 2 g/L. The different concentrations of drugs were sprayed evenly, and the same amount of water was used as blank control. Snails were surveyed using the systematic sampling method 1, 3 and 7 days post-treatment, and snail survival was observed. A fish pond was selected in Nanjian County, and 2 kg 25% WPPS was evenly sprayed on the water surface to allow the effective concentration of 20 g/L. Fish mortality was estimated 8, 24, 48 and 72 h post-treatment. RESULTS One-day treatment with 1 and 2 g/L WPPS and 2 g/L WPNES resulted in 97.99%, 97.99% and 94.11% adjusted snail mortality rates (χ2 = 3.509 and 3.509, both P values > 0.05), and the adjusted snail mortality was all 100% 3 d post-treatment with 1 and 2 g/L WPPS and 2 g/L WPNES, while 7-day treatment with 1 and 2 g/L WPPS and 2 g/L WPNES resulted in 91.75%, 86.57% and 57.76% adjusted snail mortality rates (χ2 = 14.893 and 42.284, both P values < 0.05). Treatment with 2 g/L WPPS for 72 h resulted in a 0.67% cumulative mortality rate of fish. CONCLUSIONS 25% WPPS is effective for snail control and highly safe for fish, which is feasible for use in hilly schistosomiasis-endemic regions.

Abstract
To analyze a suspected case of Clostridium botulinum food poisoning in Bayingolin Mongolian Autonomous Prefecture, Xinjiang and to help validating the diagnosis and providing technical support for clinical treatment. The basic information and clinical manifestations of food poisoning cases were investigated by using the epidemiological method of food safety accidents. The botulinum toxin genes in the samples were detected by real-time PCR and inoculation of KM mouse. The enriched bacteria were further purified and validated. PFGE and cluster analysis were performed on five isolates. Clostridium botulinum type A was detected in two homemade fermented bean samples and stool lavage fluid samples of three patients from enriched samples by toxin test and real-time PCR, and were further validated after isolation of Clostridium botulinum. PFGE showed 100% homology among five isolates. Five isolates of bacteria isolated from the stool lavage fluid of three patients and two homemade fermented bean curd were identified as the same source through PFGE. The cause of this food poisoning cases is food pollution of Clostridium botulinum type A.

Abstract
Objective: To explore the dynamic changes of morphological characteristics of patellar tendon (PT) in amateur athletes after a half-marathon using magnetic resonance imaging. Methods: A total of 19 male amateur marathon runners with 38 knee joints,aged from 26 to 53(41.5±7.9) years, running for 3 to 18 years, with a weekly running volume of 30-90 km and a monthly running volume of 100-300 km were enrolled and underwent 1.5T MRI scan before the half-marathon, within 3 hours after running and 3 days after running. Ten healthy male volunteers with 20 knee joints, who had never participated in marathon and exercised (including but not limited to running) per week for less than 150 minutes were recruited as the control group, aged from 26 to 54 (39.4±9.1) years. Firstly, the PT signal was qualitatively assessed on fat-suppressed proton density-weighted imaging (fs-PDWI) sequence to observe the presence of patellar tendinitis. Then, the length, proximal, middle and distal cross-sectional area (CSA), and volume of PT were measured using the post-processing tool ITK-SNAP, and the data were standardized. The independent sample t-test was used for comparing. One-way repeated measures analysis of variance was used to analyze the morphological changes of PT before and after half-marathon running. Results: The incidence of asymptomatic patellar tendinitis in amateur marathon runners was 26.3% (5/19). No significant MR signal changes of PT were observed in all runners after running. The proximal CSA in runners group was larger than that in controls [(4.20±0.62) mm2/kg3/4 vs (3.63±0.57) mm2/kg3/4, P<0.05], and there was no significant difference in length, medium and distal CSA and volume(all P>0.05). The length, proximal and distal CSA and volume of PT in runners group increased at 3 h after running [(47.35±3.22) mm vs (46.83±3.35) mm; (102.52±13.03) mm2 vs (98.98±13.14) mm2; (108.67±15.72) mm2 vs (100.27±14.37) mm2; (4 020.36±514.38) mm3 vs (3 826.57±499.23) mm3, all P<0.05]. There was no significant difference between before running and 3 days after running(all P>0.05). The middle CSA were not significantly different among different periods(all P>0.05). Conclusion: Marathon has effect on the normal PT morphology in male amateur marathon runners, showing an increase in proximal CSA. A half-marathon will cause reversible changes in PT length, regional CSA and volume.

Abstract
OBJECTIVE To investigate the role of miRNAs in amniotic fluid exosomes in growth and development of fetuses with Down syndrome (DS). METHODS Amniotic fluid were collected from 20 fetuses with DS and 20 normal fetuses (control) to extract amniotic exosome miRNA. MicroRNA sequencing technique was used to identify the differentially expressed miRNAs between the two groups, for which gene ontology (GO) and pathway analysis was performed. Three differentially expressed miRNAs with the strongest correlation with DS phenotype were selected for qPCR verification. Dual luciferase reporter assay was used to verify the activity of let-7d-5p for targeted regulation of BACH1. RESULTS We identified 15 differentially expressed miRNAs in DS as compared with the control group, among which 7 miRNAs were up-regulated and 8 were down-regulated. Target gene prediction results showed that the differentially expressed miRNAs targeted 17 DS-related genes. GO analysis revealed that the main functions of the target genes involved protein binding, protein transport, ATP binding, transferase activity and synapses. Pathway analysis revealed that the functional pathways were closely related with the development of the nervous system. qPCR results showed that the expression levels of miR-140-3p and let-7d-5p were significantly lower in DS group than in the control group (P < 0.05), as was consistent with miRNA sequencing results; the expression level of miR-4512 was significantly higher in DS group than in control group (P < 0.05), which was contrary to miRNA sequencing results. The results of double luciferase reporter gene assay confirmed that let-7d-5p was capable of targeted regulation of BACH1 expression. CONCLUSION Let-7d-5p in amniotic fluid exosomes may promote oxidative stress events in the brain of fetuses with DS by regulating BACH1 expression.

Abstract
Organ development is dictated by the regulation of genes preferentially expressed in tissues or cell types. Gene expression profiling and identification of specific genes in organs can provide insights into organogenesis. Therefore, genome-wide analysis is a powerful tool for clarifying the mechanisms of development during organogenesis as well as tooth development. Single-cell RNA sequencing (scRNA-seq) is a suitable tool for unraveling the gene expression profile of dental cells. Using scRNA-seq, we can obtain a large pool of information on gene expression; however, identification of functional genes, which are key molecules for tooth development, via this approach remains challenging. In the present study, we performed cap analysis of gene expression sequence (CAGE-seq) using mouse tooth germ to identify the genes preferentially expressed in teeth. The CAGE-seq counts short reads at the 5'-end of transcripts; therefore, this method can quantify the amount of transcripts without bias related to the transcript length. We hypothesized that this CAGE data set would be of great help for further understanding a gene expression profile through scRNA-seq. We aimed to identify the important genes involved in tooth development via bioinformatics analyses, using a combination of scRNA-seq and CAGE-seq. We obtained the scRNA-seq data set of 12,212 cells from postnatal day 1 mouse molars and the CAGE-seq data set from postnatal day 1 molars. scRNA-seq analysis revealed the spatiotemporal expression of cell type-specific genes, and CAGE-seq helped determine whether these genes are preferentially expressed in tooth or ubiquitously. Furthermore, we identified candidate genes as novel tooth-enriched and dental cell type-specific markers. Our results show that the integration of scRNA-seq and CAGE-seq highlights the genes important for tooth development among numerous gene expression profiles. These findings should contribute to resolving the mechanism of tooth development and establishing the basis for tooth regeneration in the future.

Abstract
Objective: Regulatory quantitative trait loci (regQTL) theory can help to evaluate the regulation function of single nucleotide polymorphisms (SNPs) on crucial biological signals from a three-dimensional perspective. The aim of this study was to investigate the effect of these regQTL-SNPs on the susceptibility of lung cancer. Methods: Based on the regQTL theory, using the database of identified lung cancer regQTL-SNPs, we screened the SNPs that may function as regQTL in the reported susceptible regions of lung cancer by genome-wide association study(GWAS), and a two-stage case-control study was conducted (screening stage: 2 331 lung cancer cases and 3 077 healthy controls; validation stage: 626 lung cancer cases and 667 healthy controls) to definite the association of related regQTL-SNPs with the susceptibility of lung cancer. Results: A total of 8 regQTL-SNPs were screened in the reported susceptible regions of lung cancer by GWAS. Among which, 3 SNPs were significantly associated with the risk of lung cancer (P<0.05) in the screening stage. Further validation results indicated that the variant T allele of rs6998591 in ADRA1A was significantly associated with increased risk of lung cancer (additive model: OR=1.33, 95%CI:1.01-1.74, P=0.040). In addition, the variant G allele of rs11202916 in ACTA2 was significantly associated with decreased risk of lung cancer (recessive model: OR=0.71, 95%CI:0.52-0.96, P=0.026). Stratified analysis indicated that the variant T allele of rs6998591 significantly increased lung squamous cell carcinoma risk (additive model: OR=1.53, 95%CI: 1.01-2.32, P=0.043), while the variant G allele of rs11202916 significantly decreased lung adenocarcinoma risk (additive model: OR=0.83, 95%CI: 0.69-0.98, P=0.031). Gene-environment interaction analysis indicated that the risk of developing lung cancer increased by 235% in smoking individuals carrying rs6998591 variant T allele compared with those non-smoking individuals carrying no rs6998591 variant T allele(OR=3.35,95%CI:2.10-5.34,P<0.001). Conclusion: There are two regQTL-SNPs that could significantly affect the susceptibility of lung cancer in the GWAS reported susceptible regions of lung cancer.

Abstract
Transmission of the crinivirus, lettuce infectious yellows virus (LIYV), is determined by a minor coat protein (CPm)-mediated virion retention mechanism located in the foregut of its whitefly vector. To better understand the functions of LIYV CPm, chimeric CPm mutants engineered with different lengths of the LIYV CPm amino acid sequence and that of the crinivirus, lettuce chlorosis virus (LCV), were constructed based on bioinformatics and sequence alignment data. The 485 amino acid-long chimeric CPm of LIYV mutant, CPmP-1, contains 60 % (from position 3 to 294) of LCV CPm amino acids. The chimeric CPm of mutants CPmP-2, CPmP-3 and CPmP-4 contains 46 (position 3 to 208), 51 (position 3 to 238) and 41 % (position 261 to 442) of LCV CPm amino acids, respectively. All four mutants moved systemically, expressed the chimeric CPm and formed virus particles. However, following acquisition feeding of the virus preparations, only CPmP-1 was retained in the foreguts of a significant number of vectors and transmitted. In immuno-gold labelling transmission electron microscopy (IGL-TEM) analysis, CPmP-1 particles were distinctly labelled by antibodies directed against the LCV but not LIYV CPm. In contrast, CPmP-4 particles were not labelled by antibodies directed against the LCV or LIYV CPm, while CPmP-2 and -3 particles were weakly labelled by anti-LIYV CPm but not anti-LCV CPm antibodies. The unique antibody recognition and binding pattern of CPmP-1 was also displayed in the foreguts of whitefly vectors that fed on CPmP-1 virions. These results are consistent with the hypothesis that the chimeric CPm of CPmP-1 is incorporated into functional virions, with the LCV CPm region being potentially exposed on the surface and accessible to anti-LCV CPm antibodies.

Abstract
OBJECTIVE To investigate the effectiveness of a new health education pathway for echinococcosis control among primary school students in regions highly prevalent for echinococcosis in China. METHODS Six primary schools were randomly selected from echinococcosis hyper-endemic regions, with 13 classes assigned to the intervention group and 9 to the control group, and all students in these 21 classes were recruited as the study subjects. Echinococcosis health education was performed through the pathway of assessing the current status-strengthening the building of teaching resources-focusing on practices in the intervention group, while routine health education was given in the control group. A questionnaire survey was performed to assess the score of echinococcosis control knowledge (including theoretical knowledge score and mean daily practical capability score) before and after the health education interventions to evaluate the effectiveness of this new health education pathway for echinococcosis control. RESULTS The mean score of echinococcosis control knowledge was 68.86 ± 18.70 points at baseline, with the mean theoretical knowledge score of 40.97 ± 10.75 points, and the mean daily practical capability score of 27.89 ± 12.50 points. Clustering analysis showed three types of populations, including "unsatisfactory", "learn and apply creatively", and "rote learning", which accounted for 24.62% (240/975), 45.74% (446/975) and 29.64% (289/975), respectively. The mean score of echinococcosis control knowledge was 81.08 ± 18.15 points in the intervention group during the final assessment, with the mean theoretical knowledge score of 43.65 ± 9.40 points, and the mean daily practical capability score of 37.43 ± 12.22 points, and both were significantly higher relative to baseline (t = -4.201 and -15.202, both P values < 0.01). The mean score of echinococcosis control knowledge was comparable between at baseline (70.55 ± 19.46 points) and final assessment (71.74 ± 19.37 points) in the control group (t = -0.87, P > 0.05). CONCLUSIONS The awareness of echinococcosis control knowledge is fair among primary school students in echinococcosis hyper-endemic regions; however, the capability of combining theoretical learning and practices requires to be improved. The health education mode based on the pathway of assessing the current status-strengthening the building of teaching resources-focusing on practices seems to remarkably improve the understanding of echinococcosis control knowledge among primary school students in echinococcosis hyper-endemic regions.

Abstract
Abstract Objective To observe the metabolomics changes of serum after skin incision of rats and to determine the wound age of skin incision. Methods A rat skin incision model was established, 21 SD rats were divided into 1 h, 2 h, 4 h, 8 h, 16 h, 24 h after skin incision groups and the control group, then blood was taken from rats in the experimental groups at the corresponding time points after injury, and taken from the control group directly. Gas chromatography-mass spectrometry (GC-MS) technology was used to detect serum metabolites and screen marker metabolites, then orthogonal partial least square-discriminant analysis (OPLS-DA) model was used to establish a regression model for the relationship between marker metabolite content and wound age to determine wound age of skin. Results GC-MS was used to detect the serum collected, and 21 marker metabolites were obtained through initial screening, and 4 marker metabolites were further analyzed and screened using multivariate statistical analysis methods. There was no correspondence between the change rule of the serum content and wound age, therefore it cannot be used directly to determine wound age. OPLS model could be used to obtain regression models of the content and wound age of 21 marker metabolites and 4 marker metabolites, both of which can determine wound age, but the prediction accuracy of the regression model of 21 marker metabolites was significantly higher. Conclusion Using metabolomics to establish a regression model of the metabolite content and wound age has the potential to be applied to skin incision wound age determination.

Abstract
In 2012, dormant canes of a proprietary wine grape (Vitis vinifera L.) accession were included in the collection of the University of California-Davis Foundation Plant Services. No virus-like symptoms were elicited when bud chips from propagated own-rooted canes of the accession were graft-inoculated onto a panel of biological indicators. However, chlorotic ringspot symptoms were observed on sap-inoculated Chenopodium amaranticolor Coste & A. Rein and C. quinoa Willd. plants, indicating the presence of a mechanically transmissible virus. Transmission electron microscopy of virus preparations from symptomatic C. quinoa revealed spherical, nonenveloped virions about 27 nm in diameter. Nepovirus-like haplotypes of sequence contigs were detected in both the source grape accession and symptomatic C. quinoa plants via high-throughput sequencing. A novel bipartite nepovirus-like genome was assembled from these contigs, and the termini of each RNA segment were verified by rapid amplification of complementary DNA ends assays. The RNA1 (7,186-nt) of the virus encodes a large polyprotein 1 of 231.1 kDa, and the RNA2 (4,460-nt) encodes a large polyprotein 2 of 148.9 kDa. Each of the polyadenylated RNA segments is flanked by 5'- (RNA1 = 156-nt; RNA2 = 170-nt) and 3'- (RNA1 = 834-nt; RNA2 = 261-nt) untranslated region sequences with >90% identities. Maximum likelihood phylogenetic analyses of the conserved Pro-Pol amino acid sequences revealed the clustering of the new virus within the genus Nepovirus of the family Secoviridae. Considering its biological and molecular characteristics, and based on current taxonomic criteria, we propose that the novel virus, named grapevine nepovirus A, be assigned to the genus Nepovirus.

Abstract
Objective: To explore the mechanism of HDAC6 mediated aggresome-autophagy-lysosome pathway in paraquat-induced autophagy in dopaminergic neurons. Methods: Human neuroblastoma cell (SH-SY5Y cell) was used as model of dopaminergic neurons in vitro. The cells were treated with terminal concentrations of 0, 25, 50, 100, 200 and 400μmol/L PQ for 24 hours, and the cells were induced by 100 μmol/L PQ for different time (0, 12, 24, 36, 48, 60 and 72 h) . Cell viability was detected by CCK-8 assay. The expression levels of HDAC6, α-syn, Dynein IC1/2, LC3, Beclin1, p62 and Lamp-1 were detected by Western blot. Immunofluorescence double-labeling method was used to observe the expression and localization of HDAC6, α-syn, Dynein IC1/2, LC3, Lamp-1 and γ-tubulin in cells. Results: CCK-8 assay showed PQ induced cell survival rate decrease in a time and dose dependent manner (R=-0.950、-0.960, P<0.05) .Western blot showed that compared with control group, the protein levels of HDAC6, α-syn, p62 in PQ-exposed group were significantly increased (P<0.05) , but there was a significant decrease in expression level of the ratio of autophagy-related protein LC3 Ⅱ/LC3 Ⅰ, Beclin1, Dynein IC1/2, Lamp-1in PQ-exposed group (P<0.05) . The results of immunofluorescence double-labeling showed that compared with the control group, the fluorescence signals of HDAC6 and α-syn in the PQ-exposed group increased, and the protein expression level increased, while the fluorescence signals of Dynein IC1/2, LC3, and Lamp-1 decreased. The protein expression level is reduced. HDAC6 gradually accumulates from the diffuse shape to the nucleus; Under normal circumstances, α-syn, Dynein IC1/2, γ-tubulin, LC3, and Lamp-1 are mainly distributed in the cytoplasm. After PQ is infected, they gather in the nucleus and co-localize with HDAC6 in the area around the nucleus. Conclusion: PQ may induce abnormal aggregation of α-syn by inducing HDAC6-mediated aggresome-autophagy-lysosomal pathway disorder.

Abstract
OBJECTIVE To research the expression and biological function of micro ribonucleic acid (miR)-645 in non-small cell lung cancer (NSCLC), and to further explore the regulatory relationship between miR-645 and tumor protein p53 inducible protein 11 (TP53I11). PATIENTS AND METHODS A total of 41 tissue samples were collected from NSCLC patients, and RNAs were extracted from these tissues and reversely transcribed. Then, the expression level of miR-645 in the 41 tissue samples of patients, as well as that in NSCLC cells and human bronchial mucosal epithelial cells, was detected by quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). In vitro functional assays [methyl thiazolyl tetrazolium (MTT) assay, colony formation assay and transwell assay] were conducted to explore the effects of miR-645 on the proliferation and migration abilities of NSCLC cells. Finally, the downstream target genes of miR-645 were predicted by bioinformatics, screened via qRT-PCR and Western blotting experiments, and verified through Dual-Luciferase reporter gene assay. RESULTS QRT-PCR results showed that the miR-645 expression was upregulated in the tissue samples of 35 out of 41 NSCC cases. Besides, the miR-645 expression was upregulated in NSCC cells compared with that in human bronchial mucosal epithelial cells. After interfering with miR-645 expression, in vitro functional assay (MTT assay, colony formation assay and transwell assay) results revealed that the cell proliferation, migration, and invasion were inhibited. According to the results of qRT-PCR and Western blotting, after knocking down the expression of miR-645 in NSCLC cells, the expression of TP53I11 was upregulated, and the results of Dual-Luciferase reporter gene assay confirmed that miR-645 could directly bind to TP53I11. CONCLUSIONS MiR-645 expression is upregulated in NSCLC tissues and cells, and the proliferation and migration of NSCLC cells are promoted by targeted regulation on the TP53I11 expression.

Abstract
Matching is a standard method for selecting research objects regarding the observational research, which controls confounding factors and improves statistical efficiency. However, its role in controlling confounding is not consistent in different observational studies. Matching can eliminate the confounding bias of matching variables in cohort studies, but checking on itself cannot eliminate confounding bias in case-control studies. In matched case-control studies, researchers may not accurately judge whether the variable is a confounder. Sometimes the variables that are not confounders are mistakenly matched. In that case, it will result in overmatching, which will lead to the decline of statistical efficiency or the introduction of unavoidable bias or increase of workload. If the real confounding factors are omitted, it will cause confounding bias. Therefore, researchers should consider what kind of matching variable selection criteria should be formulated. A directed acyclic graph is a visual graphic language that can show the complicated causality among different epidemiological research designs. This article analyzes the role of Matching in different observational research designs from the perspective of the directed acyclic graph, formulates the selection criteria for matching variables in matched case-control studies, and provides some reference suggestions for future epidemiological research design.

Abstract
Apricot vein clearing-associated virus is the type species of genus Prunevirus, family Betaflexiviridae. The virus was first discovered from an Italian apricot tree (Prunus armeniaca) showing leaf vein clearing and mottling symptoms (Elbeaino et al. 2014). Since then, apricot vein clearing-associated virus (AVCaV) has been reported in symptomatic and asymptomatic plants from other countries (Marais et al. 2015; Kinoti et al. 2017; Kubaa et al. 2014). In 2018, a domestic selection of a flowering apricot (P. mume cv. Peggy Clarke) (PC01) with no discernible foliar virus-like symptoms was received for inclusion in the Foundation Plant Services (UC-Davis) collection. The plant originated from a private Prunus collection located in California. Total nucleic acids (TNA) were isolated from PC01 leaves using MagMax Plant RNA Isolation Kit (Thermo Fisher Scientific). The TNA were analyzed for a panel of 15 Prunus-infecting viruses by reverse-transcription quantitative PCR (RT-qPCR) (Diaz-Lara et al. 2020). In addition, to screen for sap-transmissible viruses, young leaves of PC01 were homogenized in inoculation buffer and were rubbed onto leaves of herbaceous indicator plants, Chenopodium amaranticolor, C. quinoa, Cucumis sativus, and Nicotiana clevelandii (Rowhani et al. 2005). The source PC01 tested negative for the 15 screened viruses. Interestingly, vein clearing symptoms were observed on leaves of C. quinoa and C. amaranticolor plants (Figure S1). These results suggested the presence of a mechanically transmissible virus in PC01. To determine the identity of mechanically transmissible viral agent, symptomatic C. quinoa and PC01 plant were advanced for high throughput sequencing analysis. Aliquots of TNA from PC01 and C. quinoa were rRNA-depleted and used for cDNA library preparation with TruSeq Stranded Total RNA kit (Illumina). The raw reads were trimmed, de novo assembled, and subsequently were annotated using tBLASTx algorithm (Al Rwahnih et al. 2018). A total of 47,261,138 and 8,812,296 single-end reads were obtained from cDNA libraries of PC01 and C. quinoa, respectively. The de novo assembly generated near-complete contigs resembling AVCaV genome ) from both PC01 and C. quinoa, which were 99.8% identical at the nucleotide level. The longest contig (8,342 nucleotides, 73.5x coverage depth) obtained from PC01 was further completed using SMARTer RACE 5'/3' kit (Takara Bio). The complete genome sequence of AVCaV-PC01 is 8,364 nucleotides long (GenBank: MK170158). The full-length virus genome was compared with GenBank database using BLASTn, which the best hit corresponded to KY132099 with 98% identity. Additionally, AVCaV infection was confirmed in both PC01 selection and the symptomatic C. quinoa by RT-PCR as previously described (Marais et al. 2015). Lastly, symptomatic leaves of C. quinoa were used in leaf dip method to visualize virus particles by transmission electron microscope. As a result, flexuous rod-shaped virions were observed from leaf dips of symptomatic C. quinoa plants (Figure S2). Therefore, our results represent the first report of AVCaV in California, USA. Furthermore, mechanical transmission of an AVCaV isolate infecting flowering apricot to herbaceous hosts was confirmed. Field surveys and biological studies are underway to determine the prevalence of AVCaV in commercial orchards and assess its effect on tree performance.

Abstract
Abstract Objective To screen serum biomarkers after skeletal muscle contusion in rats based on gas chromatography-mass spectrometry (GC-MS) metabolomics technology, and support vector machine (SVM) regression model was established to estimate skeletal muscle contusion time. Methods The 60 healthy SD rats were randomly divided into experimental group (n=50), control group (n=5) and validation group (n=5). The rats in the experimental group and the validation group were used to establish the model of skeletal muscle contusion through free fall method, the rats in experimental group were executed at 0 h, 2 h, 4 h, 8 h, 12 h, 24 h, 48 h, 96 h, 144 h and 240 h, respectively, and the rats in validation group were executed at 192 h, while the rats in the control group were executed after three days' regular feeding. The skeletal muscles were stained with hematoxylin-eosin (HE). The serum metabolite spectrum was detected by GC-MS, and orthogonal partial least square-discriminant analysis (OPLS-DA) pattern recognition method was used to discriminate the data and select biomarkers. The SVM regression model was established to estimate the contusion time. Results The 31 biomarkers were initially screened by metabolomics method and 6 biomarkers were further selected. There was no regularity in the changes of the relative content of the 6 biomarkers with the contusion time and the SVM regression model can be successfully established according to the data of 6 biomarkers and the 31 biomarkers. Compared with the injury time [(55.344±7.485) h] estimated from the SVM regression model based on the data of 6 biomarkers, the injury time [(195.781±1.629) h] estimated from the SVM regression model based on the data of 31 biomarkers was closer to the actual value. Conclusion The SVM regression model based on metabolites data can be used for the contusion time estimation of skeletal muscles.

Abstract
Complementary (c)DNA clones corresponding to the full-length genome of T36CA (a Californian isolate of Citrus tristeza virus with the T36 genotype), which shares 99.1% identity with that of T36FL (a T36 isolate from Florida), were made into a vector system to express the green fluorescent protein (GFP). Agroinfiltration of two prototype T36CA-based vectors (pT36CA) to Nicotiana benthamiana plants resulted in local but not systemic GFP expression/viral infection. This contrasted with agroinfiltration of the T36FL-based vector (pT36FL), which resulted in both local and systemic GFP expression/viral infection. A prototype T36CA systemically infected RNA silencing-defective N. benthamiana lines, demonstrating that a genetic basis for its defective systemic infection was RNA silencing. We evaluated the in planta bioactivity of chimeric pT36CA-pT36FL constructs and the results suggested that nucleotide variants in several open reading frames of the prototype T36CA could be responsible for its defective systemic infection. A single amino acid substitution in each of two silencing suppressors, p20 (S107G) and p25 (G36D), of prototype T36CA facilitated its systemic infectivity in N. benthamiana (albeit with reduced titre relative to that of T36FL) but not in Citrus macrophylla plants. Enhanced virus accumulation and, remarkably, robust systemic infection of T36CA in N. benthamiana and C. macrophylla plants, respectively, required two additional amino acid substitutions engineered in p65 (N118S and S158L), a putative closterovirus movement protein. The availability of pT36CA provides a unique opportunity for comparative analysis to identify viral coding and noncoding nucleotides or sequences involved in functions that are vital for in planta infection.

Abstract
Background To investigate the serum level of hepcidin and its relationship with cardiovascular disease (CVD) in maintenance hemodialysis (MHD) patients. Methods Blood was obtained from 75 MHD patients before undergoing hemodialysis and 20 healthy controls. Serum hepcidin, advanced oxidation protein products (AOPP) and interleukin (IL)-6 were measured by enzyme-linked immunosorbant assay (ELISA). Spearman correlation, and binary logistic regression linear regression analyses were used to assess the relationship between serum hepcidin and other parameters. Results The serum level of hepcidin, AOPP and IL-6 was significantly up-regulated in MHD patients compared with the control (P < 0.05). Furthermore, serum hepcidin levels in patients with CVD were higher than those in patients without CVD (P < 0.05). In all MHD patients, serum hepcidin level was correlated positively with erythropoietin (EPO) dose per week (ρ = 0.251, P = 0.030), EPO resistance index (ρ = 0.268, P = 0.020), ferritin (ρ = 0.814, P < 0.001), transferin saturation (TSAT, ρ = 0.263, P = 0.023), AOPP (ρ = 0.280, P = 0.049), high sensitive C reactive protein (ρ = 0.151, P = 0.006), IL-6 (ρ = 0.340, P = 0.003) and left ventricular mass index (LVMI, ρ = 0.290, P = 0.033). Moreover, it was negatively correlated with serum pre-albumin (ρ = -0.266, P = 0.021), total iron-binding capacity (TIBC, ρ = -0.458, P < 0.001), unsaturated iron-binding capacity (UIBC, ρ = -0.473, P < 0.001) and transferrin (ρ = -0.487, P < 0.001). Linear regression analysis showed that ferritin (β = 0.708, P < 0.001), TIBC (β = -0.246, P = 0.032) and IL-6 (β = 0.209, P = 0.041) were independently associated with hepcidin. Results of binary logistic regression analysis suggested that higher serum hepcidin level (>249.2 ng/mL) was positively and independently related to CVD (OR = 1.32, 95% CI [1.20-9.56], P = 0.043). Conclusions Serum hepcidin level is associated with CVD in MHD patients, indicating that hepcidin may be a novel biomarker and therapeutic target for CVD.

Abstract
Objective: To investigate the protective effect of taurine (Tau) on hippocampus, substantia nigra neurons and microglia in paraquat (PQ) -induced Pakinson's disease-like mice. Methods: In April 2019, the specific pathogen free (SPF) C57BL/6 mice (n=36) were randomly divided into control group (NaCl) , Tau control group (150 mg/kg) , PQ exposure group (10 mg/kg PQ group, 15 mg/kg PQ group) , Tau intervention group (Tau+10 mg/kg PQ group, Tau+15 mg/kg PQ group) , respectively. Tau was used in 1 h before PQ administration for consecutive 6 weeks (twice per week) . General and neurobehavioral tests (Traction test, Open field test, Forced Swimming test, Tail suspension test, High plus maze and Object recognition test) were performed to test motor and cognitive function. After neuroethology detection, mice were euthanized and brains were collected. Nissl staining was used to detect the changes of the number and morphology of Nissl bodies in hippocampus and substantia nigra neurons of mice. Immunohistochemistry (IHC) was used to test the levels of neuron marker neuronal nuclei antigen (NeuN) , substantia nigra dopaminergic neuron marker tyrosine hydroxylase (TH) , α-synuclein (α-syn) , microglia markers ionized calcium bindingadaptor molecule-1 (Iba-1) , inducible nitric oxide synthase (iNOS) and interleukin-1β (IL-1β) in mice substantia nigra. The coexpression of Iba-1 and TH double-labeling, α-syn and TH double-labeling in mice substantia nigra were measured by immunofluorescence double staining. Results: General behavioral changes such as slow reaction and reduced action occurred in mice of PQ group. Compared with the control group, the scores of Traction test, and the time ratio of new object recognition in the PQ group decreased (P<0.05) , the fixed time of Swimming test and Tail suspension test increased (P<0.05) , the horizontal crawl number and vertical times of Open field test and the ratio of open arm residence time of High plus maze in the 15 mg/kg PQ group decreased (P<0.05) . Compared with the PQ group, the same dose of Tau+PQ group showed increased scores in Traction test (P<0.05) and decreased fixed time of Swimming test and Tail suspension test (P<0.05) . Compared with the 15 mg/kg PQ group, the horizontal crawl number of Open field test and the time ratio of new object recognition increased in the Tau+15 mg/kg PQ group (P<0.05) . Compared with the control group, the PQ group showed a decrease in the number of Nissl body in the hippocampus and substantia nigra (P<0.05) , a decrease in the number of NeuN and TH positive cells in the substantia nigra (P<0.05) , with a large number of α-syn deposition, Iba-1 activation of microglia cells, and an increase in the expression of inflammatory factors (IL-1β, iNOS) in the hippocampus and substantia nigra (P<0.05) . Compared with the PQ group, the same dose of Tau+PQ group showed the number of Nissl in the hippocampus and substantia nigra was significantly increased (P<0.05) , the number of NeuN and TH positive cells in the substantia nigra was significantly increased (P<0.05) , the expression levels of α-syn, Iba-1 and inflammatory factors (IL-1β, iNOS) in the substantia nigra were significantly decreased (P<0.05) . Conclusion: Tau could protect PQ-induced degeneration of substantia nigra dopaminergic neurons and hippocampal neuron loss by inhibiting the activation of microglia cells and release of inflammatory factors, and effectively improve the neurobehavioral and brain histopathological changes of PQ-induced PD-like mice.

Abstract
Abstract
Background
Monogenic forms of hypertension are regarded as a group of conditions characterized by early-onset and resistant hypertension, electrolyte imbalance. These alterations stem from single mutations that lead to maladaptive excretion of potassium, and consequent hypokalemia.
Purpose
This study aimed to analyze genes involved in monogenic forms of hypertension and clinical features in Chinese patients with early-onset hypertension and hypokalemia.
Methods
A total of 129 unrelated Chinese patients (89 male and 40 females; average onset age of hypertension 25±5 years) with early-onset hypertension and hypokalemia. Patients with hypertension secondary to common causes, including renal disease and renovascular disease, aortic diseases, and obstructive sleep apnea were excluded. Genomic DNA were extracted from peripheral blood leucocytes of each subject. Using next-generation sequencing, we targeted and sequenced 42 genes related to monogenic forms of hypertension. All rare variants were confirmed by Sanger sequencing.
Results
We detected 63 rare variants in 23 genes in 52 patients (40.3%). The variants in genes associated with pseudohypoaldosteronism, familial aldosteronism, pheochromocytoma or paraganglioma, and pseudohyperaldosteronism accounted for 22.2%, 23.8%, 20.6% and 11.1% respectively. Patients with rare variants had a significantly lower serum potassium (2.94±0.21 vs. 3.30±0.24 mmol/L, P<0.001) and family history of hypertension (67.3% vs. 31.2%, P<0.001). During 24±7.9 months of follow-up, several complication occurred, including stroke in 22 patients, coronary heart disease in 10, and chronic renal failure in 10. Factors associated with stroke were carrying rare variants (HR=4.371, 95% CI: 1.709–11.181, P=0.002), systolic blood pressure (HR=1.015, 95% CI: 1.004–1.037, P=0.015).
Conclusions
This study revealed a wide genetic spectrum in Chinese patients with early-onset hypertension and hypokalemia. Genetic testing helps to differentiate the diagnosis of monogenic forms of hypertension in patients with hypertension and hypokalemia, and evaluates prognosis. Those patients carrying rare variants presented with a high risk of severe complications, stroke and needed close follow-up.

Abstract
Abstract
Background
Apparent mineralocorticoid excess (AME) is a rare autosomal recessive genetic disorder caused by a mutation in the 11β-hydroxysteroid dehydrogenase type 2 gene (HSD11B2). AME is characterized by early-onset and severe hypertension, hypokalemia, and metabolic alkalosis.
Purpose
This study aimed to study the molecular genetics, clinical presentation, biochemical parameters, and treatment in the proband with AME from a non-consanguineous Chinese family.
Methods
Genomic DNA was recovered from peripheral blood leukocytes from nine subjects in this family. Next-generation sequencing and Sanger sequencing were performed to identify the HSD11B2 variants. In silico and genotype-phenotype correlations analyses were used to predict pathogenicity of candidate variants. A tailored therapy was performed for identified mutations carriers.
Results
Genetic analysis identified novel compound heterozygous HSD11B2 mutations (c.343-348del/c.1099-1101del) in the proband. In silico analysis predicted these HSD11B2 mutations were deleterious. The structural change and predicted consequences owing to the compound mutations have been modeled. The same compound mutations were not found in any other family members, 100 hypertensives, or 100 healthy controls. The proband had typical manifestations of AME, including early-onset and severe hypertension, hypokalemia, low plasma aldosterone concentration, hypokalemic alkalosis and nephrolithiasis. The probands' blood pressure and serum potassium level had returned to normal after treatmennt with dexamethasone (1.5 mg/day) and spirolactone (40 mg/day) for three months.
Conclusions
We conclude that this novel compound mutations are responsible for AME in the proband. These genetic and clinical data expand the genetic spectrum of HSD11B2 and demonstrate the pathogenic effects of identified mutations and genotype-phenotype correlations. It is emphasized that genetic diagnosis and specific treatment play an important role in patients with AME.

Abstract
Objective: To investigate the effects of Paraquat on autophagy level in SH-SY5Y cell and the mechanism of abnormal aggregation of α-synuclein. Methods: Human neuroblastoma cell (SH-SY5Y cell) was used as model of dopaminergic neurons in vitro. The cells were treated with different concentrations of PQ (0, 18.75, 37.5, 75, 150, 300, 600 μmol/L) for 24 hours, and induced by 150 μmol/L PQ for 0, 12, 24, 36, 48, 60, 72, 96 hours to detect the relative survival rate of cells and determine dose/time-effect relationship. The cells were treated with concentration of 0, 75, 150, 300, 600 μmol/L PQ for 24 hours, and induced by 150 μmol/L PQ for different hours to detect intracellular LDH activity. The expression levels of autophagy-related proteins(LC3I, LC3II, Beclin1 , Vps34 and p62) and α-synuclein were detected by Western blot. The gene expression level of α-synuclein was assayed by Real-time quantitative PCR. The expression level of α-synuclein was also evaluated by immunofluorescence. The cells were pretreated with 100 nmol/L autophagy inducer rapamycin (RAPA) for 6 hours. The expression levels of autophagy-related proteins and α-synuclein were detected by Western blot. Results: CCK8 assay showed PQ induced cell survival rate decrease in a time and dose dependent manner; Compared with control group, the activity of LDH in the cell supernatant increased significantly after PQ exposure (P<0.05) ; Western blot analysis showed the ratio of autophagy-related protein LC3II/LC3I, Beclin1 and Vps34 protein expression were significantly lower after PQ treatment while the expression of p62 protein was higher (P<0.05) ; The protein and gene expression of α-synuclein were increased significantly after PQ treatment (P <0.05) ; Immunofluorescence showed the fluorescence intensity of α- synuclein in cells was significantly enhanced (P <0.05) . Compared with PQ group, the expression levels of autophagy-related proteins LC3II/LC3I and Beclin1 were significantly increased whlie α-synuclein protein level was decreased after RAPA induction (P<0.05) . Similarly, the IF result showed the fluorescence signal of α- synuclein significantly decreased after RAPA induction (P<0.05) . Conclusion: Paraquat induced autophagy dysfunction in SH-SY5Y cells, which leads to an abnormal aggregation of α-synuclein.
