Abstract
Objective: To explore the effect of deep dermal tissue dislocation injury on skin fibrosis in pig, in order to provide some theoretical basis for burn scar treatment. Methods: The experimental research method was applied. Six 2-month-old female Duroc pigs were taken. Fifteen operative areas on the right dorsum of pigs on which medium-thick skin grafts and deep dermal tissue slices were cut and re-implanted were included into dermal in situ reimplantation group, and fifteen operative areas on the left dorsum of pigs on which medium-thick skin grafts and deep dermal tissue slices were cut and the deep dermal tissue slice was placed under the fat layer were included into the dermal dislocation group. The hair growth in the operative areas on post-injury day (PID) 7, 14, and 21 and the cross-sectional structure on PID 14 were observed in the two groups. On PID 7, 14, and 21, the skin thickness (the distance from the epidermis to the upper edge of the fat), the dermal thickness (the distance from the lower edge of the epidermis to the upper edge of the fat, excluding the fibrotic tissue thickness between the dermis and the fat), and the fibrosis tissue thickness of the dermis-fat interface (from the lower edge of the deep dermis to the upper edge of the fat in dermal in situ reimplantation group and from the lower edge of the superficial dermis to the upper edge of the fat in dermal dislocation group) in the operative areas were measured and compared between the two groups; the fibrotic tissue thickness at the dermal cutting interface (from the lower edge of the superficial dermis to the upper edge of the deep dermis) in the operative areas in dermal in situ reimplantation group was measured and compared with the fibrotic tissue thickness at the dermal-fat interface. Sirius red staining was performed to observe and compare the type Ⅰ and Ⅲ collagen content in the dermal-fat interface in the operative areas between the 2 groups and between the dermal cutting interface and dermal-fat interface in the operative areas in dermal in situ reimplantation group. Immunohistochemical staining was performed to observe the positive expressions of proliferating cell nuclear antigen (PCNA), transforming growth factor β1 (TGF-β1), fibroblast growth factor 2 (FGF-2), and hepatocyte growth factor (HGF) in the operative areas in the two groups. The sample number was 6. Data were statistically analyzed with independent sample t test. Results: On PID 7, 14, and 21, the hairs in the operative areas in dermal in situ reimplantation group were denser than those in dermal dislocation group. On PID 14, the skin cross section in the operative areas in dermal dislocation group showed a "sandwich"-like structure, while the skin cross section in the operative areas in dermal in situ reimplantation group had normal structure. On PID 7, 14, and 21, the skin thickness in the operative areas in dermal dislocation group was (4 234±186), (4 688±360), and (4 548±360) μm, respectively, which was close to (4 425±156), (4 714±141), and (4 310±473) μm in dermal in situ reimplantation group (P>0.05); the dermal thickness in the operative areas in dermal dislocation group was significantly thinner than that in dermal in situ reimplantation group (with t values of -9.73, -15.85, and -15.41, respectively, P<0.01); the fibrotic tissue thickness at the dermal-fat interface in the operative areas in dermal dislocation group was significantly thicker than that in dermal in situ reimplantation group (with t values of 14.48, 20.58, and 15.67, respectively, P<0.01); there was no statistically significant difference between the fibrotic tissue thickness at the dermal-fat interface and the dermal cutting interface in the operative areas in dermal in situ reimplantation group (P>0.05). On PID 7, 14, 21, the type Ⅲ collagen content in the dermal-fat interface in the operative areas in dermal dislocation group was increased significantly compared with that in dermal in situ replantation group (with t values of 2.65, 0.61, and 7.39, respectively, P<0.05 or P<0.01), whereas there were no statistically significant differences in the type Ⅰ collagen content at the dermal-fat interface in the operative areas between the 2 groups (P>0.05) and the type Ⅰ and Ⅲ collagen content between the dermal-fat interface and the dermal cutting interface in the operative areas in dermal in situ reimplantation group (P>0.05). On PID 7, 14, and 21, PCNA, TGF-β1, FGF-2, and HGF were positively expressed in the superficial dermis and adipose tissue in the operative areas in dermal dislocation group, while PCNA, TGF-β1, FGF-2, and HGF were positively expressed in the superficial dermis, deep dermis, and adipose tissue in the operative areas in dermal in situ reimplantation group. Conclusions: Inadequate intrinsic thickness of dermal tissue is the key factor causing fibrosis, and the biological purpose of fibrosis is to "compensate" the intrinsic thickness of the skin. Besides, adipose tissue may also be an important component of fibrotic skin repair.

Abstract
α-Farnesene is a sesquiterpene present in plants. It was first discovered in apples. It plays an important role in the plant defence response and is considered a key factor in the occurrence of superficial scald. The gene encoding α-farnesene synthase, which is the last key enzyme in the biosynthetic pathway of α-farnesene in apple fruit, has become the primary target enzyme for controlling the genetic manipulation of α-farnesene biosynthesis. In this study, the yeast one-hybrid assay and the dual luciferase assay were used to ascertain the relationship between MdLSD1 and MdAFS. Real-time PCR was used to analyse the molecular mechanism underlying the regulation of MdAFS by MdLSD1. Our results revealed that transcription factor MdLSD1, which is closely related to programmed cell death in apple fruit tissues, binds to MdAFS. Transient transformation of apple skin with vectors overexpressing MdLSD1 showed that the gene negatively regulates MdAFS. Overall, we suggest that MdLSD1 negatively regulates MdAFS. Our results are of great significance for future research on the transcriptional regulation of the α-farnesene synthase gene and provide a new direction for exploring the specific mechanism of programmed cell death involved in superficial-scald incidence.

Abstract
Objective: To explore the effect of dyslipidemia on the clinical outcome of intracytoplasmic sperm injection-embryo transfer (ICSI-ET) in infertility patients receiving donor eggs. Methods: A total of 118 patients were selected to receive egg donors and ICSI-ET at the First Affiliated Hospital of Nanjing Medical University between April 2007 and December 2020. According to the levels of triacylglycerol, serum cholesterol, high density lipoprotein (HDL), and low density lipoprotein, they were divided into dyslipidemia group (35 cases) and normal blood lipids group (83 cases). The influence of body mass index (BMI) and age was adjusted by 1∶1 propensity score matching, and the general condition and clinical outcome of the two groups were analyzed retrospectively. Finally, the relationship between lipid composition and clinical outcome was analyzed according to patients' age and BMI. Results: (1) Comparing the pre-matching dyslipidemia group with the normal blood lipids group, the BMI of the dyslipidemia group was significantly higher than that of the normal blood lipids group [(23.5±2.4) vs (22.4±2.7) kg/m2], and the embryo implantation rate was significantly lower than that of the normal blood lipids group [13.6% (8/59) vs 27.3% (36/132)], the differences were statistically significant (both P<0.05). (2) There were no significant differences in years of infertility, number of pregnancies, number of abortions, number of transplanted embryos, protocol of endometrial preparation, endometrial thickness on transplantation day and high quality embryo rate between the two groups, through propensity score matching (all P>0.05). The biochemical pregnancy rate [28.6% (10/35)], embryo implantation rate [13.6% (8/59)] and live birth rate [20.0% (7/35)] in dyslipidemia group were significantly lower than those in the normal blood lipids group (P<0.05). The clinical pregnancy rate was lower than that of the normal blood lipids group (P>0.05). (3) The results of stratified analysis showed that the level of HDL in the clinically non-pregnant group was significantly lower than that in the pregnant group in patients ≤ 35 years old [(1.5±0.3) vs (1.8±0.5) mmol/L; P<0.05]. In the overweight recipient patients, the level of HDL of the clinically non-pregnant group was lower than that of the pregnant group (P>0.05). Conclusions: Dyslipidemia significantly reduces the biochemical pregnancy rate, embryo implantation rate and live birth rate in patients with receiving donor eggs. Especially in patients aged ≤35 years old, the reduction of HDL is closely related to adverse pregnancy outcomes.

Abstract
Objective: To systematically review the prognosis of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in patients with severe aortic stenosis. Methods: A systematic search of PubMed, EMBASE, Scopus, Cochrane Library, China biomedical literature database, China journal full text database (CNKI), Wanfang database and VIP database from January 2012 to February 2022 was conducted for randomized controlled trial (RCT) that comparing TAVR and SAVR in the treatment of severe aortic stenosis. The primary outcomes were the incidence of all-cause mortality, stroke incidence, reoperation rate and complications (pacemaker implantation, atrial fibrillation) at 1 month and 1, 2, 5 years after operation. Jadad scale was used to evaluate the literature quality of RCTs. All statistical analyses were performed using the standard statistical procedures provided in RevMan 5.4.1. Results: A total of 17 studies including 11 712 patients were identified, including 6 007 patients treated with TAVR and 5 705 patients treated with SAVR. There were 4 high-quality studies and 13 medium-quality studies. The results of meta-analysis showed that the rate of new onset atrial fibrillation was lower in TAVR group than that in SAVR group (RR=0.28, 95%CI 0.21-0.38, P<0.001), and there was no significant difference in all-cause death, stroke, pacemaker implantation and reoperation rate (all P>0.05) at 30 days follow-up. At one year after TAVR and SAVR treatment, all-cause mortality (RR=0.85, 95%CI 0.74-0.97, P=0.01) and new onset atrial fibrillation (RR=0.28, 95%CI 0.20-0.39, P<0.001) were lower in TAVR group than SAVR group. However, the pacemaker implantation rate was higher in TAVR group than that of SAVR group (RR=1.79, 95%CI 1.11-2.89, P=0.02), while there was no significant difference in the incidence of stroke and reoperation between the two groups (P>0.05). At two years after TAVR and SAVR treatment, the pacemaker implantation rate was higher in TAVR group than that in SAVR group (RR=2.23, 95%CI 1.28-3.86, P=0.004), and the rate of new atrial fibrillation was lower in TAVR group than that in SAVR group (RR=0.46, 95%CI 0.38-0.56, P<0.001). There was no significant difference in all-cause death, stroke and reoperation rates between the two groups (P>0.05). At five years after TAVR and SAVR treatment, the pacemaker implantation rate (RR=1.89, 95%CI 1.13-3.17, P=0.02) and reoperation rate (RR=3.64, 95%CI 1.75-7.58, P=0.000 5) were higher in TAVR group than those in SAVR group, while the rate of new onset atrial fibrillation was lower in TAVR group than that in SAVR group (RR=0.45, 95%CI 0.37-0.55, P<0.001). There was no significant difference in all-cause death and stroke incidence between the two groups (all P>0.05). Conclusions: The all-cause mortality and the incidence of new onset atrial fibrillation after TAVR are lower than SAVR, and TAVR is a preferred therapy for patients with aortic stenosis.

Abstract
Objective: To understand the epidemiological characteristics of a local clustered epidemic caused by 2019-nCoV Delta variant in Ningbo and provide reference for the improvement of COVID-19 epidemic prevention and control. Methods: Case finding was conducted based on case definitions, and field epidemiological investigation of COVID-19 cases was carried out. In which Nasal and oropharyngeal swabs of the cases were collected for pathogen testing, and the results were analyzed with descriptive epidemiological methods. Results: A total of 74 COVID-19 cases were reported in this epidemic, and the cases were mainly mild ones, accounting for 87.84% (65/74), and there were no severe or critical cases. The epidemic curve showed a human-to-human transmission mode, indicating that a transmission for at least six generations had occurred. The age of the COVID-19 patients ranged from 2 years to 80 years, and 27.03% (20/74) of the cases were older than 60 years. The cases were mainly workers (55.41%, 41/74) and housework/the unemployed (27.03%, 20/74). The COVID-19 epidemic was limited, and no further spread to other areas occurred. The transmission chain among the cases was clear, and the gene sequencing results confirmed that the current epidemic was caused by 2019-nCoV Delta variant, which was highly homologous to the strains from other province. Conclusion: The local COVID-19 epidemic in Ningbo was caused by imported cases of COVID-19 from other province, and local community spread occurred through daily contacts between cases and contacts.

Abstract
Objective: Propionic acidemia is a rare inherited metabolic disorder caused by propionyl CoA carboxylase (PCC) deficiency. This study aims to analyze the clinical characteristics and gene variations of Chinese patients with propionic acidemia, and to explore the correlation between clinical phenotypes and genotypes. Methods: Single-center, retrospective and observational study. Seventy-eight patients of propionic acidemia (46 males and 32 females) from 20 provinces and autonomous regions were admitted from January 2007 to April 2022. Their age of initial diagnosis ranged from 7 days to 15 years. The clinical manifestations, biochemical and metabolic abnormalities, genetic variations, diagnosis, treatment and outcome were studied. Chi-Square test or Mann-Whitney U test were used for statistical analysis. Results: Among 78 cases, 6 (7.7%) were identified by newborn screening; 72 (92.3%) were clinically diagnosed after onset, and the age of onset was 2 hours after birth to 15 years old; 32 cases had early-onset disease and 40 cases had late-onset disease. The initial manifestations included lethargy, hypotonia, vomiting, feeding difficulties, developmental delay, epilepsy, and coma. Among the 74 cases who accepted gene analysis, 35 (47.3%) had PCCA variants and 39 (52.7%) had PCCB variants. A total of 39 PCCA variants and 32 PCCB variants were detected, among which c.2002G>A and c.229C>T in PCCA and c.838dupC and c.1087T>C in PCCB were the most common variants in this cohort. The variants c.1228C>T and c.1283C>T in PCCB may be related to early-onset type. The variants c.838dupC, c.1127G>T and c.1316A>G in PCCB, and c.2002G>A in PCCA may be related to late-onset disease. Six patients detected by newborn screening and treated at asymptomatic stage developed normal. The clinically diagnosed 72 cases had varied complications. 10 (12.8%) cases of them died. 62 patients improved after metabolic therapy by L-carnitine and diet. Six patients received liver transplantation because of recurrent metabolic crisis. Their clinical symptoms were markedly improved. Conclusion: The clinical manifestations of propionic acidemia are complex and lack of specificity. Newborn screening and high-risk screening are keys for early treatment and better outcome. The correlation between the genotype and phenotype of propionic acidemia is unclear, but certain variants may be associated with early-onset or late-onset propionic acidemia.

Abstract
Homoeologous exchange (HE) is a major mechanism generating post-polyploidization genetic variation with important evolutionary consequences. However, the direct impacts of HE on gene expression and transcript diversity in allopolyploids without the intertwined evolutionary processes remain to be fully understood. Here, we analyzed high-throughput RNA-seq data of young leaves from plant groups of a synthetic allotetraploid wheat (AADD), which contained variable numbers of HEs. We aimed to investigate if and to which extent HE directly impacts gene expression and alternative splicing (AS). We found that HE impacts expression of genes located within HE regions primarily via a cis-acting dosage effect, which led to significant changes in the total expression level of homoeologous gene pairs, especially for homoeologs whose original expression was biased. In parallel, HE also influences expression of a large number of genes residing in non-HE regions by trans-regulation leading to convergent expression of homoeologs. Intriguingly, when taking the original relative homoeolog expression states into account, homoeolog pairs under trans-effect are more prone to manifesting a convergent response to the HEs whereas those under cis-regulation tended to show further exacerbated subgenome-biased expression. Moreover, HE-induced quantitative, largely individual-specific, changes of AS events were detected. Similar to homoeologous expression, homoeo-AS events under trans-effect were more responsive to HE. HE therefore exerts multifaceted immediate effects on gene expression and, to a less extent, on individualized transcript diversity in nascent allopolyploidy.

Abstract
OBJECTIVE To investigate the distribution of mosquito species and their associated viruses, and identify Culex pipiens subspecies in Hami City, Xinjiang Uygur Autonomous Region. METHODS Mosquitoes were captured using mosquito trapping lamps method in Yizhou District, Yiwu County, and Balikun County of Hami City in mi-July, 2019 and 2020. The species and subspecies of all captured mosquitoes were characterized. In addition, the flavivirus, alphavirus, bunyavirus, Japanese encephalitis virus, Liaoning virus, Tahyna virus, tick-borne encephalitis virus and West Nile virus were detected using reverse-transcription PCR assay in captured mosquitoes. RESULTS A total of 1 496 mosquitoes were captured from Yizhou District, Yiwu County, and Balikun County of Hami City, belonging to 3 genus and 3 species. Cx. pipiens was the dominant mosquito species (986 mosquitoes, 65.91%), followed by Aedes caspius (457 mosquitoes, 30.55%), while Culiseta alaskaensis had the lowest number (53 mosquitoes, 3.54%). All captured Cx. pipiens mosquitoes were identified as Cx. pipiens pipiens based on the terminalia of male mosquitoes. RT-PCR assay tested negative for flavivirus, alphavirus, bunyavirus, Japanese encephalitis virus, Liaoning virus, Tahyna virus, tick-borne encephalitis or West Nile virus in captured Cx. pipiens mosquitoes. CONCLUSIONS There were 3 species of mosquitoes in Hami City from 2019 to 2020, including Cx. pipiens, Ae. Caspius and C. alaskaensis, with Cx. pipiens as the dominant mosquito species, and all captured Cx. pipiens mosquitoes were Cx. pipiens pipiens; however, no arboviruses were detected.

Abstract
Calciphylaxis is a rare disease with severe pain and high-mortality due to cutaneous ischemic necrosis and infection that currently lacks proved effective therapies. The occurrence of calciphylaxis in end stage kidney disease (ESKD) patients is known as calcific uremic arteriolopathy (CUA), which is characterized histologically by dermal microvessel calcification, intimal fibroplasia and microthrombosis. Here we innovatively treated a severe CUA patient with human amnion-derived mesenchymal stem cells (hAMSCs). A 34-year-old uremic woman was presented with progressive, painful malodorous ulcers in buttocks and mummified lower limbs. Skin pathological features supported the diagnosis of calciphylaxis. The patient was refractory to conventional multidisciplinary symptomatic therapies. With the approval of our hospital ethics committee, she was treated with hAMSCs including intravenous and local intramuscular injection, and external application of hAMSC culture supernatant to the wound area. During 15-month follow-up, the patient had regeneration of skin and soft tissues, with improved blood biochemical, inflammatory, mineral and bone metabolic indices and immunoregulation effects. After 15-month hAMSC treatment, the score of pain visual analog scale (VAS) decreased from 10 to 0, Bates-Jensen wound assessment tool (BWAT) score decreased from 65 to 13, and wound-quality of life (Wound-QoL) questionnaire score decreased from 68 to 0. We propose that hAMSC treatment is promising for CUA patients. The therapy is potentially involved in the multiple beneficial effects of inhibiting vascular calcification, stimulating angiogenesis and myogenesis, modulating adverse inflammatory and immunologic responses, promoting re-epithelialization and restoring skin integrity.

Abstract
Background WRKY (WRKY DNA-binding domain) transcription factors an important gene family that widely regulates plant resistance to biological and abiotic stresses, such as drought, salt and ion stresses. However, research on the WRKY family in almond has not yet been reported. Almond is an economically important fruit tree in Xinjiang that have strong resistance to various stresses. Results A total of 62 PdWRKY genes were identified (including six pairs of homologous genes), and the phylogenetic tree was divided into three groups according to the WRKY domain and zinc finger motifs. The members of each group had a significant number of conserved motifs and exons/introns distributed unevenly across eight chromosomes, as well as 24 pairs of fragment duplicates and nine pairs of tandem duplicates. Moreover, the synteny and Ka/Ks analyses of the WRKY genes among almond and distinct species provided more detailed evidence for PdWRKY genes evolution. The examination of different tissue expression patterns showed that PdWRKY genes have tissue-specific expression characteristics. The qRT-PCR results showed that PdWRKY genes participate in the resistance of almond to the effects of low-temperature, drought and salt stress and that the expression levels of these genes change over time, exhibiting spatiotemporal expression characteristics. It is worth noting that many genes play a significant role in low-temperature stress resistance. In addition, based on the conserved WRKY motif, 321 candidate target genes were identified as having functions in multiple pathways. Conclusions We conducted systematic bioinformatics analysis and abiotic stress research on the WRKY gene family in almond, laying the foundation for future PdWRKY genes research and improvements to almond production and breeding.

Abstract
Objective: To understand the spatial characteristics of echinococcosis and associated factors in the pastoral area of Qinghai province, and provide evidence for the effective prevention and control of echinococcosis. Methods: The number of echinococcosis cases in the pastoral areas of Qinghai in 2019 was collected to perform spatial epidemiological analysis. The thematic map of the distribution of echinococcosis cases was generated with software ArcGIS 10.8 for visual analysis and spatial autocorrelation analysis. The spatial autocorrelation and spatial scanning analysis were performed to estimate the clustering of echinococcosis with software SaTScan 9.5. Software GeoDa 1.14 and ArcGIS 10.8 were used to establish spatial lag model and geographical weighted regression model to analyze the related factors of echinococcosis epidemic. Results: In 2019, the echinococcosis surveillance covered 64 741 people in the pastoral area of Qinghai, and 829 echinococcosis cases were found, with a prevalence rate of 1.28%. The distribution of the cases had spatial correlation (Moran's I=0.41, P<0.001). The most possible clustering areas indicated by spatial scanning analysis included Banma, Jiuzhi, Dari and Gande counties of Guoluo Tibetan Autonomous Prefecture (LLR=460.77, RR=9.20, P<0.001). The prevalence of echinococcosis in the pastoral areas was positively associated with the total annual precipitation (β=0.13, P=0.036), and negatively associated with population density (β=-1.36, P=0.019) and doctors/nurse ratio (β=-25.60, P=0.026). Conclusions: The distribution of echinococcosis cases in the pastoral areas of Qinghai in 2019 had spatial correlation, and the prevalence was affected by total annual precipitation, population density, and doctors/nurse ratio.

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
Objectives: To analyze the causes of a foodborne outbreak in rural areas of Xinjiang between April 2 and April 5 in 2016. Methods: Cases and the relevant background information were obtained by consulting outpatient records of local health centers and regional people's hospitals and interviewing doctors and residents. All samples were collected by the laboratory test through epidemiological and food hygiene investigations. The χ2 test (Fisher's exact probability method) was used to compare differences in incidence rates. Molecular typing, virulence genes and single nucleotide polymorphisms (SNPS) were analyzed by using Pulsed Field Gel Electrophoresis (PFGE) and Whole Genome Sequencing (WGS). Results: A total of 142 cases were found in this study, with incidence rate at 5.7‰ (142/24 979). Among all cases, the main symptoms were nausea (94%), vomiting (92%) and abdominal pain (67%), and the incubation period was about 2 h (1-7.5 h). There were 16 Staphylococcus aureus isolates identified and all of them could produce A+C+E mixed enterotoxin. PFGE showed 100% homology. WGS further revealed that there were 9 and 1 strains contained by Sequence Type 1 (ST1) and ST5405, respectively. All ST1 strains were in the same clade on the genome tree. Among these, 7 strains shared close proximity (74 SNPs) and 2 strains shared close relationships as well (127 SNPs). The S. aureus isolates that caused the outbreak were introduced by a mutant isolate from the milk supply station. Conclusions: This foodborne outbreak was mainly caused by Staphylococcus aureus contamination.

Abstract
AIMS Lower parental education has been linked to adverse youth mental health outcomes. However, the relationship between parental education and youth suicidal behaviours remains unclear. We explored the association between parental education and youth suicidal ideation and attempts, and examined whether sociocultural contexts moderate such associations. METHODS We conducted a systematic review and meta-analysis with a systematic literature search in PubMed, PsycINFO, Medline and Embase from 1900 to December 2020 for studies with participants aged 0-18, and provided quantitative data on the association between parental education and youth suicidal ideation and attempts (death included). Only articles published in English in peer-reviewed journals were considered. Two authors independently assessed eligibility of the articles. One author extracted data [e.g. number of cases and non-cases in each parental education level, effect sizes in forms of odds ratios (ORs) or beta coefficients]. We then calculated pooled ORs using a random-effects model and used moderator analysis to investigate heterogeneity. RESULTS We included a total of 59 articles (63 study samples, totalling 2 738 374 subjects) in the meta-analysis. Lower parental education was associated with youth suicidal attempts [OR = 1.12, 95% Confidence Interval (CI) = 1.04-1.21] but not with suicidal ideation (OR = 1.05, 95% CI = 0.98-1.12). Geographical region and country income level moderated the associations. Lower parental education was associated with an increased risk of youth suicidal attempts in Northern America (OR = 1.26, 95% CI = 1.10-1.45), but with a decreased risk in Eastern and South-Eastern Asia (OR = 0.72, 95% CI = 0.54-0.96). An association of lower parental education and increased risk of youth suicidal ideation was present in high- income countries (HICs) (OR = 1.14, 95% CI = 1.05-1.25), and absent in low- and middle-income countries (LMICs) (OR = 0.91, 95% CI = 0.77-1.08). CONCLUSIONS The association between youth suicidal behaviours and parental education seems to differ across geographical and economical contexts, suggesting that cultural, psychosocial or biological factors may play a role in explaining this association. Although there was high heterogeneity in the studies reviewed, this evidence suggests that the role of familial sociodemographic characteristics in youth suicidality may not be universal. This highlights the need to consider cultural, as well as familial factors in the clinical assessment and management of youth's suicidal behaviours in our increasingly multicultural societies, as well as in developing prevention and intervention strategies for youth suicide.

Abstract
Objective: To understand the characteristics and trend of the premature death rate of 4 major chronic diseases in Ji'nan from 2015 to 2020. Methods: The death cause surveillance data and population data during 2015-2020 in Ji'nan were collected, and abbreviated life table, Joinpoint regression analysis and other methods were used to analyze the characteristics and change trends of the premature death rates of 4 major chronic diseases. Results: The crude mortality rate and age standardized mortality rate changes for the 4 major chronic diseases from 2015 to 2020 range from 568.65/100 000 to 604.06/100 000 and 366.77/100 000 to 432.48/100 000, respectively. The annual premature death rate of 4 major chronic diseases declined by 3.33% averagely from 2015 to 2020 (95%CI: -6.25%--0.32%), which might be explained by the declines of the premature death rates of cardiovascular and cerebrovascular diseases [average annual percentage change (AAPC)=-3.23%, 95%CI: -6.32%--0.05%] and cancer (AAPC=-3.58%,95%CI:-6.83%--0.21%). The average decline rate in women (AAPC=-4.19%,95%CI:-7.56%- -0.70%) was higher than that in men (AAPC=-2.92%,95%CI: -5.65%--0.11%). Conclusions: The premature death rate of 4 major chronic diseases showed a downward trend in Ji'nan from 2015 to 2020. Men should be considered as a key population in the prevention and control of 4 major chronic diseases, and attention should also be paid to the non-significant declines in the premature death rates of chronic respiratory diseases and diabetes.

Abstract
Spinal bionic therapy is the application of bionics concept, by imitating the natural anatomical structure and physiological function of the spine, to treat spinal diseases using various modern technology, materials and equipment .How to repair or preserve the anatomical structure and function of spine to the maximum extent while treating spinal diseases is an important content of spinal bionic therapy.Firstly, the use of movable spinal implants not only preserves the spinal mobility function to a certain extent, reduces the degeneration of adjacent segments, but also reduces the incidence of internal fixation fracture and improves the long-term efficacy.Secondly, with the help of the development of three dimensional printing technology, personalized artificial prostheses can be made to fill the spinal structure with complex defects, and biological scaffolds and functional prostheses with anti-tumor drugs can not only realize the biomimetic and functional spine anatomy, but also become a multiplier of the efficacy of anti-tumor drugs.Thirdly, in the design and manufacture of spinal orthopaedic braces, computer aided design and manufacturing technology can make spinal orthopaedic braces more comfortable with better orthopaedic effect and ergonomic characteristics.How to apply bionics concepts and relate technologies to spinal surgery have not been determined yet, and no relevant diagnosis and treatment guidelines have been formulated.It is foreseeable that with the continuous development of medical technology, the content of spinal bionic therapy will be gradually enriched and improved, and become a powerful measure to overcome difficulties in the diagnosis and treatment of spinal surgery diseases.

Abstract
OBJECTIVE To identify the differentially expressed proteins in different liver tissues in the mouse model of cystic echinococcosis (CE), so as to provide insights into the research and development of therapeutic drugs targeting CE. METHODS Female Kunming mice at ages of 6 to 8 weeks were randomly assigned into the CE group and the control group. Mice in the CE group were intraperitoneally infected with 2 000 Echinococcus multilocularis protoscoleces, while mice in the control group were injected with the same volume of physiological saline. All mice in both groups were sacrificed after breeding for 350 d, and the lesions (the lesion group) and peri-lesion specimens (the peri-lesion group) were sampled from the liver of mice in the CE group and the normal liver specimens (the normal group) were sampled from mice in the control group for data independent acquisition (DIA) proteomics analysis, and the differentially expressed proteins were subjected to Gene Ontology (GO) term enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. RESULTS A total of 26 differentially expressed proteins were identified between the lesion group and the normal group and between the peri-lesion group and the normal group, including 8 up-regulated proteins and 18 down-regulated proteins. GO term enrichment analysis showed that these differentially expressed proteins were predominantly enriched in endoplasmic reticulum membrane (biological components), oxidoreductase activity (molecular function) and oxoacid metabolic process and monocarboxylic acid metabolic process (biological processes). KEGG pathway enrichment analysis revealed that the differentially expressed protein Acyl-CoA oxidase 1 (Acox1), which contributed to primary bile acid biosynthesis during the fatty acid oxidation, was involved in peroxisome signaling pathway, and the differentially expressed protein fatty acid binding protein 1 (Fabp1), which contributed to fatty acid transport, was involved in the peroxisome proliferator-activated receptor (PPAR) signaling pathway. CONCLUSIONS Differentially expressed proteins are identified in the liver specimens between mouse models of CE and normal mice, and some differentially expressed proteins may serve as potential drug targets for CE.

Abstract
OBJECTIVE To identify the differentially expressed proteins in different liver tissues in the mouse model of alveolar echinococcosis using high-resolution mass spectrometry with data independent acquisition (DIA), and to identify the key proteins contributing to the pathogenesis of alveolar echinococcosis. METHODS Protoscoleces were isolated from Microtus fuscus with alveolar echinococcosis and the experimental model of alveolar echinococcosis was established in female Kunming mice aged 6 to 8 weeks by infection with Echinococcus multilocularis protoscoleces. Mice were divided into the experimental and control groups, and animals in the experimental group was injected with approximately 3 000 protoscoleces, while mice in the control group were injected with the same volume of physiological saline. Mouse liver specimens were sampled from both groups one year post-infection and subjected to pathological examinations. In addition, the lesions (the lesion group) and peri-lesion specimens (the peri-lesion group) were sampled from the liver of mice in the experimental group and the normal liver specimens (the normal group) were sampled from mice in the control group for DIA proteomics analysis, and the differentially expressed proteins were subjected to bioinformatics analysis. RESULTS A total of 1 020 differentially expressed proteins were identified between the lesion group and the normal group, including 671 up-regulated proteins and 349 down-regulated proteins, and 495 differentially expressed proteins were identified between the peri-lesion group and the normal group, including 327 up-regulated proteins and 168 down-regulated proteins. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that these differentially expressed proteins were involved in peroxisome, peroxisome proliferator-activated receptor (PPAR) and fatty acid degradation pathways, and the peroxisome and PPAR signaling pathways were found to correlate with liver injury. Several differentially expressed proteins that may contribute to the pathogenesis of alveolar echinococcosis were identified in these two pathways, including fatty acid binding protein 1 (Fabp1), Acyl-CoA synthetase long chain family member 1 (Acsl1), Acyl-CoA oxidase 1 (Acox1), Enoyl-CoA hydratase and 3-hydroxyacyl CoA dehydrogenase (Ehhadh) and Acetyl-Coenzyme A acyltransferase 1B (Acaa1b), which were down-regulated in mice in the experimental group. CONCLUSIONS A large number of differentially expressed proteins are identified in the liver of the mouse model of alveolar echinococcosis, and Fabp1, Acsl1, Acox1, Ehhadh and Acaa1b may contribute to the pathogenesis of alveolar echinococcosis.

Abstract
Objective: To compare the efficacy and safety of venetoclax (VEN) combined with azacitidine (AZA) versus CAG regimen combined with decitabine (DAC) in elderly patients with relapsed acute myeloid leukemia (AML). Methods: From January 2018 to August 2020, the clinical data of forty-five elderly patients with relapse AML at the First Affiliated Hospital of Soochow University were retrospectively analyzed, including 31 males and 14 females. The median age was 66 (60-80) years old. Eighteen patients were administrated with VEN and AZA, while the other 27 were in CAG with DAC. The complete remission (CR) rate, partial remission (PR) rate, total remission rate (ORR), adverse events and overall survival (OS) were compared between the two groups. Results: At the end of the treatment, the ORR in VEN with AZA group was 77.8% (14/18); including 11 CR and 3 PR. In CAG with DAC group, the ORR was 37.0% (10/27); including 8 CR and 2 PR (P=0.007). Subgroup analysis suggested that VEN with AZA had a higher ORR in patients stratified as intermediate and poor-risk (P=0.013) or with DNA methylation mutations (P=0.007). Main adverse events in both groups were bone marrow suppression, infections, nausea and vomiting, anorexia and fatigue. Grade Ⅲ-Ⅳ cytopenia developed in lower incidence of VEN with AZA group, such as leukopenia (66.7% vs. 100%, P=0.002), anemia (50.0% vs. 92.6%, P=0.002), thrombocytopenia (72.2% vs. 96.3%, P=0.031) and neutropenia (61.1% vs. 92.6%, P=0.014). In addition, less grade Ⅲ-Ⅳ infections occurred in VEN with AZA group (66.7% vs. 33.3%, P=0.028), as well as grade Ⅲ-Ⅳ gastrointestinal events (40.7% vs. 11.1%, P=0.032), grade Ⅲ-Ⅳ fatigue (55.6% vs.11.1%, P=0.003) compared with CAG with DAC group. The 1-year OS in VEN with AZA group versus CAG with DAC group was 42.9% and 31.6% respectively (P=0.150). Conclusion: VEN combined with AZA proves favorable efficacy and tolerablity in elderly patients with relapsed AML.

Abstract
Polyploidy, or whole-genome duplication (WGD), often induces dramatic changes in gene expression due to "transcriptome shock. " However, questions remain about how allopolyploidy (the merging of multiple nuclear genomes in the same nucleus) affects gene expression within and across multiple tissues and developmental stages during the initial foundation of allopolyploid plants. Here, we systematically investigated the immediate effect of allopolyploidy on gene expression variation in an artificial allopolyploidy system consisting of a constructed allotetraploid wheat (AADD genome, accession AT2) and its diploid progenitors Triticum urartu and Aegilops tauschii. We performed comprehensive RNA sequencing of 81 samples from different genotypes, tissues, and developmental stages. First, we found that intrinsic interspecific differences between the diploid parents played a major role in establishing the expression architecture of the allopolyploid. Nonetheless, allopolyploidy per se also induced dramatic and asymmetric patterns of differential gene expression between the subgenomes, and genes from the D subgenome exhibited a more drastic response. Second, analysis of homoeolog expression bias (HEB) revealed that the D subgenome exhibited significant expression bias and that de novo-generated HEB was attributed mainly to asymmetrical differential gene expression. Homoeolog-specific expression (HSE) analyses showed that the cis-only regulatory pattern was predominant in AT2, reflecting significant divergence between the parents. Co-expression network analysis revealed that homoeolog expression connectivity (HEC) was significantly correlated with sequence divergence in cis elements between subgenomes. Interestingly, allopolyploidy-induced reconstruction of network modules was also associated with different HSE patterns. Finally, a transcriptome atlas of spike development demonstrated that the phenotypic similarity of AT2 to T. urartu may be attributed to the combination of relatively stable expression of A-subgenome genes and drastic downregulation of their D-subgenome homoeologs. These findings provide a broad, multidimensional characterization of allopolyploidy-induced transcriptomic responses and suggest that allopolyploidy can have immediate and complex regulatory effects on the expression of nuclear genes.

Abstract
OBJECTIVES Although low muscle mass may make an under-appreciated contribution to increasing the risk of cardiovascular diseases, no prospective studies have explored the association between low muscle mass and carotid atherosclerosis. We investigated whether muscle mass was related to a higher carotid intima-media thickness (C-IMT) and carotid artery plaque in a community-based population. METHODS The study included 1,253 asymptomatic participants without known cardiovascular disease, who underwent carotid ultrasonography at baseline in 2013-2014 and received a re-examination in 2015-2016. The skeletal muscle mass index was estimated using a bioelectrical impedance analyzer. We assessed the relationship between the skeletal muscle mass index and the development of C-IMT and carotid plaque, both, using multivariate-adjusted logistic regression models. RESULTS During the follow up, 400 (51.0%) subjects with normal C-IMT at baseline developed elevated C-IMT and 215 (17.2%) subjects developed carotid plaque. The risk of elevated C-IMT occurrence linearly decreased with an increase in skeletal muscle mass index quintiles or its continuous data, after multivariate-adjustment in men and women, respectively (both P for trend < 0.05; both P < 0.05). Subgroup analyses showed that this association was BMI-dependent. Besides, there was an inverse association between a high skeletal muscle mass index and carotid artery plaque in women, but the association disappeared after multivariate adjustment. In men, the skeletal muscle mass index was not associated with the incidence of carotid plaque. CONCLUSIONS Skeletal muscle mass was inversely associated with the incidence of carotid atherosclerosis, suggesting muscle mass maintenance may play a role in modifying atherosclerosis.

Abstract
We studied the effects of Huaier polysaccharide (HP) in doxorubicin-induced myocardial injury in mice. The content of HP in Trametes robiniophila Murr medicinal fungus determined by the phenol-sulfuric acid method was 85.25%. In the in vitro model, the viability of H9c2 cells was significantly increased after HP treatment compared to the control, while doxorubicin (DOX) decreased this parameter. The inhibitory effect of DOX on cell viability was attenuated after HP treatment. In the in vivo model, the body weight of mice in DOX and DOX+HP groups was significantly decreased compared to the control group. ECG showed significantly elevated ST segment in the DOX group, while in the DOX+HP group, ECG was close to normal. The levels of cardiotoxicity markers cTnI and lactate dehydrogenase in the DOX+HP group were significantly lower than in the DOX group. In the DOX group, the myocardial tissue had obvious structural disorder and interfibrillar vacuoles. In the DOX+HP group, the cardiomyocytes were neatly arranged without interfibrillar vacuoles. The expression of the ferroptosis marker glutathione peroxidase 4 was increased in the DOX+HP group compared to the DOX group. Thus, our study reveals that HP attenuated DOX-induced myocardial injury in mice probably by regulating ferroptosis.

Abstract
OBJECTIVE Coal workers' pneumoconiosis (CWP) is a chronic inflammatory and fibrotic pulmonary disease that involves a complex interaction of multiple environmental and genetic factors. Polymorphism, as a genetic factor, may affect the onset of the disease in susceptible populations. The present study investigated the association between the polymorphisms of six genes and CWP risk in a Chinese Han population. PATIENTS AND METHODS Six polymorphisms (CASP8 rs3834129, IL1A rs1800587, IL6 rs1800796, IL4 rs2070874, TNFA rs361525, and NLRP3 rs1539019) were examined in 222 CWP subjects and 247 dust-exposed control subjects. RESULTS The CASP8 rs3834129 Ins/Del genotype significantly decreased CWP risk (p=0.040; adjusted odds ratio [OR] = 0.586; 95% confidence interval [CI] 0.367-0.935) compared with the Ins/Ins genotype. Stratification analyses revealed a significant interaction between the heterozygous Ins/Del genotype and age. Compared with the Ins/Ins + Del/Del genotype, this was particularly evident among subjects aged 41-60 (p<0.001; adjusted OR = 0.054; 95% CI 0.007-0.420) and those with an exposure time of 20-29 years (p=0.014; adjusted OR = 0.392; 95% CI 0.183-0.842). This decreased risk was also found in the group with former smokers (p=0.012; adjusted OR = 0.448; 95% CI 0.238-0.844). Findings revealed that the heterozygous Ins/Del genotype of CASP8 rs3834129 was related to a significantly decreased risk of stage I CWP (p=0.045; adjusted OR = 0.592; 95% CI 0.353-0.992), but not stage II or III CWP. CONCLUSIONS Our study indicated that the heterozygous Ins/Del genotype of CASP8 rs3834129 significantly decreased CWP risk in a Chinese Han population.

Abstract
Objective: To analyze the effects of different types of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on 24-hour ambulatory blood pressure in patients with type 2 diabetes mellitus and hypertension. Method: In this meta-analysis, we searched for randomized controlled trials on the effect of SGLT2i on 24-hour ambulatory blood pressure in patients with type 2 diabetes and hypertension. Three databases, namely PubMed, Web of Science and Cochrane Library, were searched. The search was organized on the concept of 3 conceptual groups: the first group contained terms used to describe SGLT2i, the second group contained terms related to blood pressure, and the third group contained terms used to describe randomized controlled trials. The search time was from the establishment of the database to December 2020. The inclusion and exclusion criteria were formulated in accordance with the requirements of the Cochrane systematic review. According to whether the heterogeneity of the study was significant or not, a random effect model or a fixed effect model were used to conduct the analysis on the impact of different types of SGLT2i on 24-hour ambulatory blood pressure and day and night blood pressure in patients with type 2 diabetes and hypertension. Further subgroup analysis was performed to define potential factors, which might lead to clinical heterogeneity. Results: Seven clinical trials were finally included. The result of the meta-analysis showed that compared with placebo group, SGLT2i could reduce the 24-hour dynamic systolic blood pressure of patients with type 2 diabetes and hypertension by 4.36 mmHg (1 mmHg=0.133 kPa). Reduction was 4.59, 3.74, 5.06, and 3.64 mmHg by canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin respectively; SGLT2i could reduce the 24-hour dynamic diastolic blood pressure of patients with type 2 diabetes and hypertension by 2.20 mmHg, and the reduction was 2.30, 1.22, 2.00, and 2.69 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin respectively. SGLT2i could reduce the daytime systolic blood pressure of patients with type 2 diabetes and hypertension by 5.25 mmHg, and reduction was 5.38, 4.87, 6.00, and 4.37 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin, respectively. Simultaneously, SGLT2i could reduce the diastolic blood pressure of patients with type 2 diabetes and hypertension by 2.62 mmHg, and the reduction was 2.56, 2.47, and 2.80 mmHg by canagliflozin, empagliflozin and ertugliflozin, respectively. SGLT2i could reduce the nighttime systolic blood pressure of patients with type 2 diabetes and hypertension by 3.62 mmHg, and the reduction was 2.09, 2.06, 3.92, and 2.45 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin, respectively. At the same time, SGLT2i could reduce the nighttime diastolic blood pressure of patients with type 2 diabetes and hypertension by 1.60 and 1.51 mmHg, the reduction was 1.53 and 2.58 mmHg by canagliflozin, empagliflozin and ertugliflozin, respectively. Conclusion: SGLT2i can reduce 24-hour ambulatory blood pressure in patients with type 2 diabetes and hypertension.

Abstract
The Kelvin-Helmholtz instability at the magnetospheric boundary plays a crucial role in solar wind-magnetosphere-ionosphere coupling, particle entry, and energization. The full extent of its impact has remained an open question due, in part, to global models without sufficient resolution to capture waves at higher latitudes. Using global magnetohydrodynamic simulations, we investigate an event when the Magnetospheric Multiscale (MMS) mission observed periodic low-frequency waves at the dawn-flank, high-latitude boundary layer. We show the layer to be unstable, even though the slow solar wind with the draped interplanetary magnetic field is seemingly unfavorable for wave generation. The simulated velocity shear at the boundary is thin ( ∼ 0.65 R E ) and requires commensurately high spatial resolution. These results, together with MMS observations, confirm for the first time in fully three-dimensional global geometry that KH waves can grow in this region and thus can be an important process for energetic particle acceleration, dynamics, and transport.

Abstract
Chronic ankle instability is a chronic sports injury disease characterized by recurrent sprains, feeling of instability, pain, swelling and other symptoms after an initial sprain. Research on the pathological mechanism of chronic ankle instability still cannot explain the diversity of symptoms. In the past, the surgical indications for chronic ankle instability only emphasized mechanical joint laxity. However, most patients with chronic symptoms after a lateral ankle sprain may not have a typical complaint of mechanical instability. More patients presented with persistent pain or functional instability as the chief complaint. Surgical treatment also has a certain effect on the symptoms of functional instability, but the surgical indications of functional instability are mainly based on subjective symptoms. At present, there is a lack of objective indicators for surgery, which is still controversial. Further in-depth research on the mechanism of chronic ankle instability is needed to guide the formulation of diagnosis and treatment strategies.

Abstract
Millions of unsolicited medical inquiries are received by pharmaceutical companies every year. It has been hypothesized that these inquiries represent a treasure trove of information, potentially giving insight into matters regarding medicinal products and the associated medical treatments. However, due to the large volume and specialized nature of the inquiries, it is difficult to perform timely, recurrent, and comprehensive analyses. Here, we combine biomedical word embeddings, non-linear dimensionality reduction, and hierarchical clustering to automatically discover key topics in real-world medical inquiries from customers. This approach does not require ontologies nor annotations. The discovered topics are meaningful and medically relevant, as judged by medical information specialists, thus demonstrating that unsolicited medical inquiries are a source of valuable customer insights. Our work paves the way for the machine-learning-driven analysis of medical inquiries in the pharmaceutical industry, which ultimately aims at improving patient care.
