Abstract
Objective: To explore the clinical characteristics, pathological features, and diagnosis and treatment strategies of nasal chondromesenchymal hamartoma (NCMH) in infants and young children. Methods: A retrospective analysis was conducted on seven cases of NCMH infants and young children admitted to Beijing Children's Hospital, Capital Medical University from April 2015 to January 2022. The cohort included 5 males and 2 females, aged from 6 days to 2 years and 3 months. General information, clinical symptoms, imaging findings, treatment plans, postoperative complications, recurrence and follow-up time were collected, summarized and analyzed. Additionally, immunohistochemical characteristics of the lesion were examined. Results: The clinical symptoms of 7 children included nasal congestion, runny nose, open mouth breathing, snoring during sleep, difficulty feeding, and strabismus. All patients underwent electronic nasopharyngoscopy examination, with 5 cases of tumors located in the right nasal cavity and 2 cases in the left nasal cavity. No case of bilateral nasal cavity disease was found. All 7 patients underwent complete imaging examinations, with 5 patients underwent MRI and CT examinations, 1 patient underwent CT examination only, and 1 patient underwent MRI examination only. The CT results showed that all tumors were broad-based, with uneven density, multiple calcifications and bone remodeling, and some exhibited multiple cystic components. The MRI results showed that the tumor showed low signal on T1 weighted imaging and high or slightly high signal on T2 weighted imaging. All patients were diagnosed through histopathological examination and immunohistochemistry, including 7 cases of Ki-67 and SMA (+), 5 cases of S-100 and Vimentin (+), and all EMA and GFAP were negative. All patients underwent endoscopic resection surgery through the nasal approach, with 3 cases using navigation technology. Five cases of tumors were completely removed, and two cases of tumors were mostly removed. No nasal packing was performed after surgery, and no postoperative nasal, ocular, or intracranial complication occurred in all patients. Follow up assessments conducted 6 to 84 months post-surgery revealed no instances of tumor recurrence in any of the patients. Conclusions: The clinical symptoms of children with NCHM mainly depend on the size and location of the tumor. Nasal endoscopic surgery is the main treatment method. In cases where critical structures like the skull base or orbit are implicated, staged surgical interventions may be warranted. Long-term follow-up is strongly advised to monitor for any potential recurrence or complications.

Abstract
Objective: To compare the prevalence of frailty and related factors in middle-aged and elderly people aged ≥45 years in island and mountainous areas of Taizhou, Zhejiang Province. Methods: Based on cross-sectional design, stratified cluster sampling and quota sampling methods were adopted. One administrative district was randomly selected from each of six coastal and three inland administrative districts in Taizhou during July to August, representing two different geographical terrains. In the island area (Jiaojiang District), all residents aged ≥45 years were included by cluster sampling. In the mountainous area (Xianju County), participants were selected through quota sampling, with same gender and age distributions. Data about their demographic characteristics, lifestyle and health-related factors were collected through questionnaire surveys and laboratory examinations. The prevalence of frailty was assessed using the Fried frailty phenotype scale. Hierarchical analysis and multivariate logistic regression analysis were used to compare the influencing factors of frailty. Results: A total of 1 011 local residents were studied, in whom island and mountainous residents accounted for 48.1% (486/1 011) and 51.9% (525/1 011) respectively; men and women accounted for 45.9% (464/1 011) and 54.1% (547/1 011) respectively. Middle-aged (45-49 years), younger elderly (60-74 years), and older elderly (≥75 years) residents accounted for 38.6% (390/1 011), 44.6% (451/1 011), and 16.8% (170/1 011) respectively. The overall prevalence rate of frailty was 3.6% (36/1 011), the prevalence rate was 3.7% (17/464) in men and 3.5% (19/547) in women. The prevalence rates in age groups 45-59,60-74 years and ≥75 years were 0.3% (1/390), 2.2% (10/451), and 14.7% (25/170), respectively. The prevalence rates of frailty and pre-frailty in island area were 6.0% (29/486) and 39.1% (190/486), respectively, which was higher than those in mountainous area (1.3%, 7/525) and (30.9%, 162/525). After adjusting for potential confounding factors, the risk for frailty in island residents was significantly higher than that in mountainous residents (aOR=1.55,95%CI: 1.07-2.25,P=0.019). In island area, older age (60-74 years:aOR=2.52,95%CI: 1.56-4.13; ≥75 years:aOR=11.65,95%CI:5.38-26.70), being women (aOR=1.94,95%CI: 1.20-3.17), suffering from depression (aOR=1.09,95%CI:1.02-1.17) were associated with frailty symptoms. In mountainous area, older age was also associated with an increased risk of frailty symptoms, but the OR value was lower than those in island area (60-74 years: aOR=1.74,95%CI:1.04-2.94;≥75 years: aOR=4.78,95%CI:2.45-9.50). Polydrug use (aOR=2.08,95%CI: 1.14-3.80) and suffering from depression (aOR=1.10,95%CI: 1.02-1.18) had significant positive association with frailty symptoms. Higher education level had significant negative association with frailty symptoms (junior high school: aOR=0.40,95%CI: 0.21-0.75; senior high school and technical secondary school: aOR=0.29,95%CI: 0.15-0.53; college or above:aOR=0.22,95%CI: 0.11-0.42). Conclusions: The prevalence of frailty in middle-aged and elderly community residents was significantly higher in island area than in mountainous area in Taizhou. The frailty-related factors varied with area. The elderly people (≥75 years) and women in island area had higher risk for frailty. Older age and suffering from depression were the independent risk factors for frailty. It is necessary to pay attention to the health risk factors and special environment in island area, and take comprehensive intervention measures to delay the process of debilitation and improve the quality of life of middle-aged and elderly people.

Abstract
To explore the allergen sensitization status of patients with respiratory allergic diseases in Shanxi Province, and to provide a basis for the diagnosis, treatment and prevention of allergic diseases. It is a cross-sectional study, a total of 1 680 patients with allergic rhinitis and/or asthma diagnosed at the Department of Allergic Reaction of Shanxi Bethune Hospital from July 2021 to June 2023 who underwent allergen sIgE testing and/or skin prick test were retrospectively enrolled.There were 772 males and 908 females.The age range was 3 to 88 years. The median age was 35 years.There were 108 cases in the child group (≤12 years old), 102 cases in the adolescent group (13-17 years old), 819 cases in the youth group (18-40 years old), 498 cases in the middle-aged group (41-65 years old), and 153 cases in the elderly group (>65 years old). There were 333 cases in the allergic rhinitis group, 827 cases in the allergic asthma group, and 520 cases in the allergic rhinitis with asthma group. There were 1 254 urban patients and 426 rural patients.There were 253 cases in the northern Shanxi region, 1 195 cases in the central Shanxi region, and 232 cases in the southern Shanxi region. Statistical analyses were performed using the χ 2 test or Fisher's exact probability method to compare the differences in allergen sIgE positivity rates by sex, age, disease, living environment, and geography. The results showed that 1 027 patients (61.1%) were positive for at least one allergen sIgE, with Artemisia having the highest rate of positivity (603/1 680, 35.9%), followed by ragweed (302/1 680, 18.0%) and dust mite combinations (245/1 680, 14.6%). The number of individuals with single-allergen sIgE positivity was 357 (357/1 027, 34.8%), with the highest number of single-allergen sIgE positive results associated with Artemisia (114/357, 31.9%). The number of multiple-allergen sIgE positive results was 670 cases (670/1 027, 65.2%), with the highest number of patients having 2 allergen sIgE positive results (243/670, 36.3%). The overall positivity rate for allergen sIgE was significantly higher among males than among females (65.7% vs. 57.3%, χ2=12.405, P<0.001). Overall positivity for inhalant allergen sIgE was higher in the child and adolescent groups (88.0% vs. 88.2% vs. 59.8% vs. 40.2% vs. 19.0%, χ2=223.372, P<0.001), and food allergen sIgE positivity was highest in the child group (54.6% vs. 36.3% vs. 26.0% vs. 18.9% vs. 21.6%,χ2=66.383,P<0.001). The sIgE positivity rate of inhalant allergens was significantly higher in the allergic rhinitis group and the allergic rhinitis with asthma group than in the allergic asthma group, except for cockroaches and molds (P<0.05). The overall positive rate of allergen sIgE was significantly higher among urban patients than among rural patients (66.2% vs. 46.2%, χ2=53.230, P<0.001). The difference in the overall positive rate of allergen sIgE among patients from different regions was not statistically significant (56.1% vs. 62.0% vs. 62.1%, χ2=3.140, P=0.208). The sIgE positivity of dust mite combinations was significantly higher in the central Shanxi region and the southern Shanxi region than in the northern Shanxi region (15.5% vs. 18.1% vs. 7.1%,χ2=14.411, P=0.001). In conclusion, artemisia was the most important sensitizer for respiratory allergic diseases in Shanxi Province. The types of allergens and positivity rates were different for different sexes, ages, diseases, living environments, and regions. Therefore, patients with allergic diseases should be tested for allergens to help with the diagnosis, treatment and prevention of allergic diseases.

Abstract
Objective: To examine the early and midterm surgical outcome of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCA) using revised surgical strategies. Methods: A retrospective analysis of clinical data, surgical methods, and follow-up results was performed of 104 cases of PA/VSD/MAPCA in Department of Cardiovascular Surgery, Guangzhou Women and Children's Medical Center from January 2017 to September 2022. There were 55 males and 49 females, aged (M(IQR)) 33.9(84.0) months (range: 0.5 to 209.6 months) at the first surgical procedures. The anatomical classification included 89 cases of type B and 15 cases of type C. The number of major aortopulmonary collateral arteries was 4.2 (3.0) (range: 1 to 8). The Kaplan-Meier method was used for survival estimation. Results: In the first stage of surgery, 50 patients underwent a complete primary repair, 12 patients underwent partial repair, 32 patients underwent palliative right ventricular-pulmonary artery connection, and only 10 patients chose the Blalock-Taussig shunt. There were 10 cases of early death. In the second stage, 14 patients underwent complete repair and 4 patients underwent partial repair with no early death. The interval between the two surgeries was 19 (10) months (range: 9 to 48 months). Finally, during the 40 (34) months follow-up period, a total of 64 patients were complete repair and the right/left ventricular pressure ratio after complete repair was 0.63±0.16 (range: 0.36 to 1.00). Survival analysis showed that survival rates at 1 and 5 years after first-stage surgery were both 89.4% (95%CI: 83.5% to 95.3%). At 28 (34) months (range: 1 to 67 months) of follow-up after complete repair, the survival analysis showed that the survival rates at 1 and 5 years were both 95.2% (95%CI: 89.9% to 100%). Conclusions: Using combined approaches tailored to individual patients and optimized unifocalization strategy, the complete repair rate at one stage and the cumulative complete repair rate at 5 years improved significantly with a lower right/left ventricular pressure ratio and satisfactory early and intermediate survival.

Abstract
Polydnaviruses (PDVs), obligatory symbionts with parasitoid wasps, function as host immune suppressors and growth and development regulator. PDVs can induce host haemocyte apoptosis, but the underlying mechanism remains largely unknown. Here, we provided evidence that, during the early stages of parasitism, the activated Cotesia vestalis bracovirus (CvBV) reduced the overall number of host haemocytes by inducing apoptosis. We found that one haemocyte-highly expressed CvBV gene, CvBV-26-4, could induce haemocyte apoptosis. Further analyses showed that CvBV-26-4 has four homologs from other Cotesia bracoviruses and BV from wasps in the genus Glyptapanteles, and all four of them possessed a similar structure containing 3 copies of a well-conserved motif (Gly-Tyr-Pro-Tyr, GYPY). Mass spectrometry analysis revealed that CvBV-26-4 was secreted into plasma by haemocytes and then degraded into peptides that induced the apoptosis of haemocytes. Moreover, ectopic expression of CvBV-26-4 caused fly haemocyte apoptosis and increased the susceptibility of flies to bacteria. Based on this research, a new family of bracovirus genes, Bracovirus apoptosis-inducing proteins (BAPs), was proposed. Furthermore, it was discovered that the development of wasp larvae was affected when the function of CvBV BAP was obstructed in the parasitized hosts. The results of our study indicate that the BAP gene family from the bracoviruses group is crucial for immunosuppression during the early stages of parasitism.

Abstract
Objective: To understand the incidence and causes of HIV/AIDS death patients in Taizhou from 1998 to 2022. Methods: The data were collected from the AIDS Integrated Prevention and Control Information System of China Information System for Diseases Control and Prevention and Taizhou Chronic Disease Information Management System. By the end of 2022, a total of 5 126 HIV/AIDS patients living in Taizhou for a long time were included, SAS 9.4 was used for Kruskal-Wallis test, χ2 test and trend analysis. Results: From 1998 to 2022, a total of 796 HIV/AIDS patients died, with a fatality rate of 15.53% (796/5 126), in whom 52.26% (416/796) died within one year after confirmation. The proportion of HIV/AIDS patients who died within one year decreased (trend χ2=5.60, P<0.001). For the constituent of death causes, there were 140 (17.59%) deaths of AIDS, 237 (29.77%) deaths of malignant tumors, 99 (12.44%) deaths of cardiovascular disease, 58 (7.29%) deaths caused by injuries, 160 (20.10%) deaths due to other causes, and 102 (12.81%) deaths due to unknown causes. The constituent ratio of deaths of malignant tumor, cardiovascular disease and other causes increased over time (trend χ2=1.92, P=0.028; trend χ2=2.81, P=0.003; trend χ2=2.07, P=0.020). There were differences in the distribution of death causes in HIV/AIDS cases in terms of age, occupation, marital status, ethnic group, educational level and mode of transmission (all P<0.05). The average age of the death cases due to cardiovascular disease was higher than other death cases, the cases who died from AIDS had shorter survival time and the lower initial CD4+T cells after confirmation compared with all other death cases, and the time interval from confirmation to treatment in HIV/AIDS patients with unknown death causes was longer than those of all other death cases (all P<0.05). Conclusions: The constituent ratio of non-AIDS related deaths in HIV/AIDS patients in Taizhou was relatively high and showed an upward trend during 1998-2022.

Abstract
Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

Abstract
Objective: To assess the impact of Friday surgery on clinical outcomes in elderly patients with hip fracture under multidisciplinary treatment. Methods: A retrospective cohort study. The clinical data of 414 geriatric patients with hip fractures admitted to Zhongda Hospital Affiliated with Southeast University from January 2018 to March 2021 were analyzed retrospectively, including 126 males and 288 females with a mean age of (81.3±7.6) years. The patients were divided into two groups based on whether they underwent surgery on Friday or not. The Friday group(n=69) and the non-Friday group(n=345) were compared in terms of general information, American Society of Anesthesiologists(ASA) classification, fracture type, injury to admission time, preoperative waiting time, surgical method, anesthesia type and use of intensive care unit (ICU) fast track. Propensity score matching (PSM) was performed based on age, ASA grade, time from injury to admission, preoperative waiting time, hemoglobin and albumin levels at admission. Clinical outcomes were collected and compared between the two groups, including length of hospital stay, total hospitalization cost and 30-day, 90-day and 1-year mortality rates, and postoperative complications. Multivariate logistic regression analyses were conducted to identify influencing factors for 1-year mortality in geriatric patients with hip fracture. Results: Baseline data showed statistically significant differences in hemoglobin, albumin and preoperative waiting time between the two groups (all P<0.05). After PSM matching, 69 patients were included in each group, and no significant differences were observed in baseline data between the two groups (all P>0.05). There was no significant differences in 30-day mortality rate (4.3% vs 0, P=0.080), 90-day mortality rate (7.2% vs 1.4%, P=0.095), length of hospital stay [(10.85±4.45)d vs (10.92±3.68)d, P=0.919], total hospitalization cost [(60.9±15.4) thousands yuan vs (59.1±15.4) thousands yuan, P=0.489], postoperative complications [pneumonia (11.6% vs 13.0%, P=0.796), cardio-cerebrovascular complications (11.6% vs 8.7%, P=0.573) and delirium (5.7% vs 2.9%, P=0.245)] between the Friday group and the non-Friday group (all P>0.05). However, the 1-year mortality rate was higher in the Friday group than that in the non-Friday group(18.8% vs 4.3%, P=0.008). Multivariate analysis revealed that surgery on Friday (OR=11.222, 95%CI: 2.198-57.291, P=0.004), low hemoglobin levels at admission (OR=0.920, 95%CI: 0.875-0.967, P=0.001), hemiarthroplasty treatment (OR=5.127, 95%CI: 1.308-20.095, P=0.019) and longer surgery duration (OR=0.958, 95%CI: 0.927-0.989, P=0.009) were influencing factors for 1-year mortality in geriatric patients with hip fracture. Conclusions: In the context of multidisciplinary treatment, Friday surgery does not increase short-term mortality, length of hospital stay, total hospitalization cost or incidence of complications in geriatric patients with hip fracture. However, it remains a influencing factor for 1-year mortality in those patients.

Abstract
Chalcidoidea is one of the most biologically diverse groups among Hymenoptera. Members are characterized by extraordinary parasitic lifestyles and extensive host ranges, among which several species attack plants or serve as pollinators. However, higher-level chalcidoid relationships remain controversial. Here, we performed mitochondrial phylogenomic analyses for major clades (18 out of 25 families) of Chalcidoidea based on 139 mitochondrial genomes. The compositional heterogeneity and conflicting backbone relationships in Chalcidoidea were assessed using various datasets and tree inferences. Our phylogenetic results supported the monophyly of 16 families and polyphyly of Aphelinidae and Pteromalidae. Our preferred topology recovered the relationship (Mymaridae+(Signiphoridae+Leucospidae)+(Chalcididae+((Perilampidae+Eucharitidae)+ remaining Chalcidoidea)))). The monophyly of Agaonidae and Sycophaginae was rejected, while the gall-associated ((Megastigmidae+Ormyridae)+(Ormocerinae+Eurytomidae)) relationship was supported in most results. A six-gene inversion may be a synapomorphy for most families, whereas other derived gene orders may introduce confusion in phylogenetic signals at deeper nodes. Dating estimates suggested that Chalcidoidea arose near the Jurassic/Cretaceous boundary and that two dynamic shifts in diversification occurred during the evolution of Chalcidoidea. We hypothesized that the potential codiversification between chalcidoids and their hosts may be crucial for accelerating the diversification of Chalcidoidea. Ancestral state reconstruction analyses supported the hypothesis that gall-inducers were mainly derived from parasitoids of gall-inducers, while other gall-inducers were derived from phytophagous groups. Taken together, these findings advance our understanding of mitochondrial genome evolution in the major interfamilial phylogeny of Chalcidoidea.

Abstract
Objective: Single-cell RNA sequencing (scRNA-seq) was used to analyze the developing mouse molars, in order to construct a spatiotemporal development atlas of pulp cells, and further to reveal the developmental process and regulatory mechanism of tooth development. Methods: Ten mandibular first molars from C57BL/6 mice in postnatal day (PN) 0 and 3 were respectively dissected and digested to obtain single-cell suspensions. scRNA-seq was performed on 10× Genomics platform. PN 7 mouse molar scRNA-seq data were obtained from our previous study. PN 0, 3, and 7 scRNA-seq data were integrated for following analysis. The initial quality control, mapping and single cell expression matrix construction were performed by Cell Ranger. Quality control, standardization, dimensional reduction and cluster analysis were performed by using Seurat. Monocle was used to generate the pseudotime trajectory. Scillus was used to perform gene ontology analysis. In order to detect the spatiotemporal change of different population of pulp cells, the marker genes of each cluster were demonstrated by RNAscope in situ hybridization. Results: There were twenty-six cell clusters within mouse molars, which were identified as eight different cell types, including dental pulp cells, dental follicle cells, epithelial cells, immune cells, endothelial cells, perivascular cells, glial cells and erythrocytes. We further re-clustered and analyzed dental pulp cells. Cluster 0 were mature pulp cells, which located at the upper portion of crown. The main functions of cluster 0 were osteogenesis and extracellular structure organization. Cluster 1 were apical papilla cells, which located at the apical part of roots, whose main functions were extracellular structure organization and organ development. Cluster 2 were cycling cells, which were actively proliferated, resided in the lower portion of the crown. Cluster 3 and 4 were preodontoblasts and odontoblasts, respectively. Their functions were closely related to biomineralization. The proportion of mature pulp cells increased with the development process, while the proportion of cycling cells and odontoblast lineage decreased. According to the expression pattern of marker genes of each cluster, we constructed a cell atlas of dental pulp. Pseudotime trajectory analysis found there were two development trajectories within dental pulp. They both started from SPARC related modular calcium binding 2 (Smoc2)+ dental papilla cells, then went through DNA topoisomerase Ⅱ alpha (Top2a)+ cycling cells, and finally divided into coxsackie virus and adenovirus receptor (Cxadr)+ mature pulp cells or dentin sialophosphoprotein (Dspp)+ odontoblasts two lineages. Conclusions: scRNA-seq could fully discover the intercellular heterogeneity of cells on transcriptome level, which provides a powerful tool to study the process and regulatory mechanism of organ development.

Abstract
We presented a case of successful awake endotracheal intubation in a patient with a giant goiter and severe tracheal stenosis. The patient had difficulty in airway management during the perioperative anesthesia due to tracheal deviation and stenosis caused by tumor compression. We applied a visual laryngeal mask combined with fiberoptic bronchoscope to visualize the whole procedure of endotracheal intubation, from visually assessing the glottic, subglottic, and the tracheal conditions, to evaluating the pressure of the tumor on the trachea and the maximum tracheal tube diameter that could be passed. During the entire process, the patient remained awake, maintained spontaneous breathing, and actively cooperated with the clinical staff. Hence, we demonstrated that this method is safe, effective, operable, and could be generalized as a form of endotracheal intubation for patients with known difficult airways.

Abstract
Polydnavirus (PDV) is a parasitic factor of endoparasitic wasps and contributes greatly to overcoming the immune response of parasitized hosts. Protein tyrosine phosphatases (PTPs) regulate a wide variety of biological processes at the post-transcriptional level in mammals, but knowledge of PDV PTP action during a parasitoid−host interaction is limited. In this study, we characterized a PTP gene, CvBV_12-6, derived from Cotesia vestalis bracovirus (CvBV), and explored its possible regulatory role in the immune response of the host Plutella xylostella. Our results from qPCR show that CvBV_12-6 was highly expressed in hemocytes at an early stage of parasitization. To explore CvBV_12-6 function, we specifically expressed CvBV_12-6 in Drosophila melanogaster hemocytes. The results show that Hml-Gal4 > CvBV_12-6 suppressed the phenoloxidase activity of hemolymph in D. melanogaster, but exerted no effect on the total count or the viability of the hemocytes. In addition, the Hml-Gal4 > CvBV_12-6 flies exhibited decreased antibacterial abilities against Staphylococcus aureus. Similarly, we found that CvBV_12-6 significantly suppressed the melanization of the host P. xylostella 24 h post parasitization and reduced the viability, but not the number, of hemocytes. In conclusion, CvBV_12-6 negatively regulated both cellular and humoral immunity in P. xylostella, and the related molecular mechanism may be universal to insects.

Abstract
Objective: To investigate the influence factors of poor efficacy after flap repair operation in patients with pressure ulcers. Methods: The retrospective case series study was conducted. From January 2011 to June 2021, 125 patients with stage Ⅲ and Ⅳ pressure ulcers treated in Hainan General Hospital met the inclusion criteria. There were 82 males and 43 females, aged 15-90 (57±20) years. According to the postoperative effects, the patients were divided into poor efficacy group (47 cases) and good efficacy group (78 cases). The clinical data of patients in the two groups were collected, including the age, gender, location, stage, size, and bone exposure of pressure ulcers, preoperative microorganism culture results of wound exudate sample, whether combined with osteomyelitis, diabetes, lower limb paroxysmal myospasm, and gatism or not, the number of surgical debridement combined with negative-pressure wound therapy, type of surgical flap, postoperative position, and preoperative albumin, leukocyte, C-reactive protein (CRP), and hemoglobin. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, and chi-square test. The binary multivariate logistic regression analysis was conducted to screen the independent risk factors influencing the poor efficacy after flap repair operation in 125 patients with stage Ⅲ and Ⅳ pressure ulcers. Results: The ratio of patients with lower limb paroxysmal myospasm in poor efficacy group was 22/47, which was significantly higher than 3/78 in good efficacy group (χ2=33.83, P<0.01). The preoperative hemoglobin level of patients in poor efficacy group was (102±17) g/L, which was significantly lower than (113±20) g/L in good efficacy group (t=-3.24, P<0.01). The preoperative CRP level of patients was 39.1 (14.1, 91.6) mg/L in poor efficacy group, which was significantly higher than 15.3 (6.6, 42.0) mg/L in good efficacy group (Z=-3.04, P<0.01). There were no statistically significant differences in other indexes between patients in the two groups (P>0.05). Multivariate logistic regression analysis showed that age, lower limb paroxysmal myospasm, and preoperative hemoglobin level were the independent risk factors for poor efficacy after flap repair operation in patients with pressure ulcers (with odds ratios of 1.03, 40.69, and 0.97, 95% confidence intervals of 1.00-1.06, 9.18-180.39, and 0.95-1.00, respectively, P<0.05 or P<0.01). Conclusions: Poor efficacy after flap repair operation in patients with pressure ulcers is affected by many factors, among which the age, lower limb paroxysmal myospasm, and preoperative hemoglobin level are the independent risk factors.

Abstract
Studying the microbial symbionts of eukaryotic hosts has revealed a range of interactions that benefit host biology. Most eukaryotes are also infected by parasites that adversely affect host biology for their own benefit. However, it is largely unclear whether the ability of parasites to develop in hosts also depends on host-associated symbionts, e.g., the gut microbiota. Here, we studied the parasitic wasp Leptopilina boulardi (Lb) and its host Drosophila melanogaster. Results showed that Lb successfully develops in conventional hosts (CN) with a gut microbiota but fails to develop in axenic hosts (AX) without a gut microbiota. We determined that developing Lb larvae consume fat body cells that store lipids. We also determined that much larger amounts of lipid accumulate in fat body cells of parasitized CN hosts than parasitized AX hosts. CN hosts parasitized by Lb exhibited large increases in the abundance of the bacterium Acetobacter pomorum in the gut, but did not affect the abundance of Lactobacillus fructivorans which is another common member of the host gut microbiota. However, AX hosts inoculated with A. pomorum and/or L. fructivorans did not rescue development of Lb. In contrast, AX larvae inoculated with A. pomorum plus other identified gut community members including a Bacillus sp. substantially rescued Lb development. Rescue was further associated with increased lipid accumulation in host fat body cells. Insulin-like peptides increased in brain neurosecretory cells of parasitized CN larvae. Lipid accumulation in the fat body of CN hosts was further associated with reduced Bmm lipase activity mediated by insulin/insulin-like growth factor signaling (IIS). Altogether, our results identify a previously unknown role for the gut microbiota in defining host permissiveness for a parasite. Our findings also identify a new paradigm for parasite manipulation of host metabolism that depends on insulin signaling and the gut microbiota.

Abstract
Objective: To explore the characteristics and prognostic value of pulmonary hemodynamics in patients with acute coronary syndrome (ACS). Methods: From a prospective multicenter registry study of pulmonary hypertension due to left heart disease, consecutive ACS patients who underwent coronary angiography in combination with left and right heart catheterization during hospitalization between January 2013 and November 2016 were involved. The primary endpoint was all-cause mortality. The prognostic variables identified by the Lasso analysis were included in the Global Registry of Acute Coronary Events (GRACE) score. Model performance was evaluated before and after the addition of hemodynamic parameters. Results: A total of 251 patients were enrolled, with age of (63.7±11.5) years. A total of 198 males (78.9%) and 53 females (21.1%) were recruited, and the median follow-up time was 34.7 months. Right heart catheterization-assessed mean pulmonary arterial pressure (mPAP), systolic pulmonary arterial pressure (sPAP) and diastolic pressure gradient (DPG) were found to be significant predictors for survival in ACS. Adjusted for age and sex, the adjusted HR (95%CI) of mPAP, sPAP and DPG were 1.068 (1.015-1.123), 1.033 (1.002-1.065) and 1.094 (1.008-1.187), respectively (P<0.05). Applied to the present cohort of 251 patients, the median of the GRACE score was 123 points, with a C-index of 0.703 (95%CI: 0.615-0.791) for predicting mortality. After the addition of mPAP or DPG to the GRACE score, the C-index increased to 0.715 (95%CI: 0.629-0.801) or 0.711 (95%CI: 0.625-0.797), respectively. When comparing two models before and after the addition of mPAP or DPG, the integrated discriminatory index (IDI) was 4.3% (95%CI: 0.2%-13.5%, P=0.030) and 3.0% (95%CI: 0.2%-11.1%, P=0.020), respectively. Conclusion: Pulmonary hemodynamics can be predictive for survival in ACS patients, providing incremental prognostic value to risk assessment in ACS.

Abstract
The tea grey geometrid Ectropis grisescens has long been a significant insect pest of tea plants in China. Two parasitoids, Parapanteles hyposidrae and Protapanteles immunis (Hymenoptera: Braconidae: Microgastrinae), are the most important parasitoids in the larval stage of E. grisescens. Yet, the potential of these two parasitoids for controlling the tea grey geometrid is not known. Here, we studied the parasitism performance of these two parasitoid species on different host densities under different temperatures as well as the interference effect of parasitoid density. The results showed that both parasitoid species, Pa. hyposidrae and Pr. immunis, exhibited a Type II functional response towards the tea grey geometrid E. grisescens at four tested temperatures. With increasing the density of E. grisescens larvae, the number of parasitized larvae increased until a maximum was reached. The highest number of hosts parasitized by Pa. hyposidrae or Pr. immunis reached 14.5 or 14.75 hosts d-1 at 22 °C, respectively. The estimated values of instantaneous searching efficiency (a) and handling time (h) for Pa. hyposidrae or Pr. immunis were 1.420 or 3.621 and 0.04 or 0.053 at 22 °C, respectively. Pr. immunis performed better than Pa. hyposidrae under higher temperatures. The parasitism rate by a single female parasitoid decreased with increasing parasitoid density at different temperatures, resulting in a reduction of searching efficiency. The findings of this study showed that Pr.immunis could be a better effective biocontrol agent than Pa. hyposidrae against the tea grey geometrid.

Abstract
Objective: Using two measuring tools to examine the prevalence and correlates of neurocognitive impairment (NCI) as well as characteristics of neurocognitive performance among people with HIV (PWH) on antiretroviral treatment (ART). Methods: A total of 2 250 treated PWH from the Comparative HIV and Aging Research in Taizhou (CHART) were recruited in Taizhou, Zhejiang province. The Chinese version of the Mini-mental State Examination (MMSE) and the International HIV Dementia Scale (IHDS) were used to evaluate their neurocognitive performance. Cluster analysis was conducted on the seven cognitive domains in the scale. Results: Among 2 250 treated PWH, 48.0% (1 080/2 250) were aged 45 to 89, 79.2% (1 782/2 250) were male, and 37.8% (852/2 250) had primary school education or below. The prevalence of neurocognitive impairment judged by MMSE and IHDS among HIV-infected people was 14.3% (321/2 250) and 31.8% (716/2 250), respectively. Aged 60 to 89 (aOR=2.63, 95%CI:1.52-4.56), depressive symptoms (aOR=5.58, 95%CI:4.20-7.40) and treatment with EFV (aOR=2.86, 95%CI:1.89-4.34) were main risk factors of NCI diagnosed by MMSE. Male (aOR=0.71, 95%CI:0.51-1.00), overweight (aOR=0.63, 95%CI:0.44-0.89), and high education level (aOR=0.11, 95%CI:0.05-0.25) were protective factors of NCI diagnosed by MMSE. Aged 60 to 89 (aOR=3.10, 95%CI:2.09-4.59), depressive symptoms (aOR=1.78, 95%CI:1.44-2.20) and treatment with EFV (aOR=1.79, 95%CI:1.41-2.29) were risk factors of NCI diagnosed by IHDS. Male (aOR=0.75, 95%CI:0.58-0.97), underweight (aOR=0.67, 95%CI:0.47-0.96), baseline CD4+ T lymphocyte (CD4) counts ≥350 cells/μl (aOR=0.69, 95%CI:0.53-0.91) and high education level (aOR=0.23, 95%CI:0.14-0.39) were protective factors of NCI diagnosed by IHDS. The neurocognitive performance of HIV-infected people can be divided into four main types. Among four types, age, gender, education level, alcohol drinking, depressive symptoms, waist-to-hip ratio, hypertension, diabetes, baseline CD4 counts and treatment with EFV were different statistically (all P<0.05). Conclusions: There are four main types of neurocognitive performance in treated PWH. The prevalence of NCI is high among this population, underscoring the need for tailored prevention and intervention.

Abstract
Millimeter wave systems based on powerful gyrotron can deliver megawatt microwave power, which is an important auxiliary heating method for magnetic confinement fusion devices. Reflective gratings are normally used as quasi-optical polarizers for polarization control of the wave in such systems. Based on the coordinate transformation method, we developed a numerical code to study the broadband polarization strategy. By considering the synthesis of two polarizers, we designed a pair of polarizers in the W band. Calculation results indicated that almost arbitrary polarization can be achieved in a wide frequency range. To verify the design, we set up a low-power test platform and experiments were carried out. The performance of the polarizers was tested from 80 to 105 GHz with a step of 5 GHz. The test results agreed well with the numerical results, indicating that the design is reasonable. With the development of multi-frequency gyrotrons, the study in this paper can be used as a reference for the design of broadband polarizers of multi-frequency millimeter wave systems.

Abstract
Objective: To analyze the mortality level and tendency of road traffic injury in Shandong province from 2012 to 2020. Methods: Based on the data of road traffic deaths from the cause of death registration system in Shandong province from 2012 to 2020, the mortality rates of road traffic injury were calculated by sex, age, area, and injury type. The mortality was standardized based on the age structure of the Chinese population in the sixth Population Census in 2010. The annual percent change (APC) and average annual percent change (AAPC) of the mortalities and the standarized mortalities were calculated by using Joinpoint regression model, and the trends were also examined. Results: In 2020, the crude mortality of road traffic injury in Shandong Province was 15.58/100 000, and the standardized mortality was 12.90/100 000. From 2012 to 2020, the standardized mortality of road traffic injury in Shandong province showed a downward trend with AAPC of -5.4%. The standardized mortality of middle-south mountain areas, male and children aged 0-14 years in Shandong showed a significantly decreasing trend with AAPC of -6.8%, -6.1% and -6.0%, respectively. The standardized mortality of people aged 65 years and over did not decrease significantly, but the number of deaths increased significantly by 50.96% in 2020 (5 780 cases), compared with those in 2012 (3 829 cases). The standardized mortality of pedestrian and motorcyclists decreased significantly with AAPC of -7.5% and -6.7%, respectively. There was no significant change in the standardized mortality among people who rode motor vehicles or bicycles. Conclusion: From 2012 to 2020, the standardized mortality of road traffic injury in Shandong Province showed an obvious downward trend, but the standardized mortality of people aged 65 years and over did not decrease significantly. In the future, it is still necessary to take government-led, multi-sectoral collaboration, with a focus on comprehensive preventive measures, to further reduce road traffic injury mortality.

Abstract
The mortality of female breast cancer in Shandong Province has increased since the 1970. The differential decomposition analysis found that the slight decline in the crude mortality of breast cancer among women was entirely due to non-demographic factors during the 1970-1990, and the significant increase in the crude mortality was due to a combination of demographic and non-demographic factors since the 1990. The contribution rate of demographic factor has gradually increased from 53.5% in 2004-2005 to 59.5% in 2011-2013, while that of non-demographic factor has decreased from 46.5% to 40.5%. The women aged 45-64 years old were the major population of female breast cancer deaths, accounting for 40%-60% of total breast cancer deaths in different times, and then the mortality in female aged 55-64 years old increased rapidly, with increases of 52.12%, 115.19% and 29.01% in 2011-2013 over the 1970-1974, 1990-1992 and 2004-2005, respectively (Z=-7.342,P<0.001). Compared with 1970-1974, the age-standardized mortality rate of rural women increased by 41.86% in 2011-2013 (Z=-17.933, P<0.001), and that of urban women increased by 18.62% in 2011-2013 (Z=-25.642, P<0.001). The age-standardized mortality rate of breast cancer in urban women was higher than that in rural women in different times (all P<0.05). The spatial scan analysis found that eastern Shandong Province was found to be a sustained high-risk area for death, and other high-risk areas were transferred from north to southwest of Shandong between 1970 and 2013.

Abstract
Different from other trauma, the scar and pigmentation formed after healing of burn wound not only hinder beauty but also easily lead to a series of sequential psychological problems, such as depression and anxiety. Music therapy, as a supplementary treatment, is widely used in many fields including medical and health care and psychological regulation. However, affected by factors such as medical resources, the awareness and acceptance of music therapy among burn treatment workers in China are still low. Based on the clinical characteristics of burns, this paper matches the applicability of music therapy with it, summarizes the supplementary application of music therapy in the field of burn treatment, expounds this natural science with both science and aesthetics, and puts forward feasible suggestions for its future development.

Abstract
Objective: To explore the correlation between club drug use and anal canal human papillomavirus (HPV) infection in HIV-negative and HIV-positive men who have sex with men (MSM) in Taizhou. Methods: A cross-sectional survey was conducted in Taizhou. HIV-negative MSM were recruited by convenient sampling in voluntary counseling and testing clinics of Taizhou prefectural CDC from August 2016 to October 2017, and HIV-positive MSM were recruited through the routine follow-up and management by Taizhou prefectural CDC from August 2016 to June 2019. A face-to-face questionnaire interview was conducted to collect the information about the socio-demographic characteristics, sexual orientation, sexual behavior, club drug use and other information of the participants. Anal canal swabs were collected for HPV genotyping. The correlation between club drug use and the prevalence of HPV infection were evaluated with χ2 test and logistic regression analysis. Results: A total of 69 HIV-negative and 345 HIV-infected MSM were included. The prevalence of any type of anal canal HPV infection in HIV-negative MSM (27.5%, 19/69) was lower than that in HIV-positive MSM (66.4%, 229/345) (χ2=36.114,P<0.001). The prevalence of self-reported club drug use in HIV-negative MSM was higher (17.4%, 12/69) than that in HIV-positive MSM (7.0%, 24/345) (χ2=7.886, P=0.005). For HIV-negative MSM, the prevalence of club drug use was higher in MSM who had homosexual group sex (P=0.036); the prevalence of HPV infection was 50.0% (6/12) in club drug users and 22.8% (13/57) in non-club drug users (χ2=3.674, P=0.055). For HIV-positive MSM, the prevalence of HPV infection was 70.8% (17/24) in club drug users and 66.0% (212/321) in non-club drug users (χ2=0.230, P=0.632). Multivariable logistic regression model showed that HPV infection in MSM was positively correlated with HIV infection (OR=5.42, 95%CI: 2.92-10.06), and the association between HPV infection and club drug use (OR=1.66, 95%CI: 0.75-3.71) was not significant. Conclusions: HIV infection was positively correlated with anal canal HPV infection in MSM in Taizhou. Club drug use was positively correlated with high-risk sexual behaviors, while its association with HPV infection needs further study.

Abstract
RNA interference pathways mediated by different types of small non-coding RNAs (siRNAs, miRNAs and piRNAs) are conserved biological responses to exotic stresses, including viral infection. Aside from the well-established siRNA pathway, the miRNA pathway and the piRNA pathway process viral sequences, exogenously or endogenously, into miRNAs and piRNAs, respectively. During the host-virus interaction, viral sequences, including both coding and non-coding sequences, can be integrated as endogenous viral elements (EVEs) and thereby become present within the germline of a non-viral organism. In recent years, significant progress has been made in characterizing the biogenesis and function of viruses and EVEs associated with snRNAs. Overall, the siRNA pathway acts as the primarily antiviral defense against a wide range of exogenous viruses; the miRNA pathways associated with viruses or EVEs function in antiviral response and host gene regulation; EVE derived piRNAs with a ping-pong signature have the potential to limit cognate viral infection.

Abstract
Polydnaviruses (PDVs) are obligatory symbionts of parasitoid wasps and play an important role in suppressing host immune defenses. Although PDV genes that inhibit host melanization are known in Microplitis bracovirus, the functional homologs in Cotesia bracoviruses remain unknown. Here, we find that Cotesia vestalis bracovirus (CvBV) can inhibit hemolymph melanization of its host, Plutella xylostella larvae, during the early stages of parasitization, and that overexpression of highly expressed CvBV genes reduced host phenoloxidase activity. Furthermore, CvBV-7-1 in particular reduced host phenoloxidase activity within 12 h, and the injection of anti-CvBV-7-1 antibody increased the melanization of parasitized host larvae. Further analyses showed that CvBV-7-1 and three homologs from other Cotesia bracoviruses possessed a C-terminal leucine/isoleucine-rich region and had a similar function in inhibiting melanization. Therefore, a new family of bracovirus genes was proposed and named as C-terminal Leucine/isoleucine-rich Protein (CLP). Ectopic expression of CvBV-7-1 in Drosophila hemocytes increased susceptibility to bacterial repression of melanization and reduced the melanotic encapsulation of parasitized D. melanogaster by the parasitoid Leptopilina boulardi. The formation rate of wasp pupae and the eclosion rate of C. vestalis were affected when the function of CvBV-7-1 was blocked. Our findings suggest that CLP genes from Cotesia bracoviruses encoded proteins that contain a C-terminal leucine/isoleucine-rich region and function as melanization inhibitors during the early stage of parasitization, which is important for successful parasitization.

Abstract
Objective: To explore the difference of high-risk factors between early-onset and late-onset pre-eclampsia, and to further understand high-risk factors of pre-eclampsia. Methods: Clinical data of pre-eclampsia pregnant women in 160 medical institutions in China in 2018 were retrospectively analyzed, including 8 031 cases of early-onset pre-eclampsia and 12 969 cases of late-onset pre-eclampsia. The proportion of high-risk factors, different body mass index (BMI) and age stratification between early-onset group and late-onset group were compared. Results: (1) Univariate analysis of high-risk factors: the proportions of high-risk factors in early-onset group and late-onset group were compared, and the differences were statistically significant (all P<0.05). Among them, the proportions of primipara and multiple pregnancy in early-onset group were lower than those in late-onset group, while the proportions of pregnant women with advanced age, irregular antenatal examination, obesity, family history of hypertension, pre-eclampsia, diabetes, kidney diseases, immune system diseases and assisted reproductive technology were higher than those in late-onset group. (2) Hierarchical analysis of BMI: the proportion of pregnant women with BMI≥24 kg/m2 in early-onset group [48.2% (2 828/5 872) vs 45.5% (4 177/9 181), respectively; P=0.001] and the proportion of pregnant women with BMI ≥28 kg/m2 in early-onset group [19.5% (1 143/5 872) vs 18.0% (1 656/9 181), respectively; P=0.028] were significantly higher than those in late-onset group. (3) Age stratification analysis: the proportion of pregnant women aged 35-39 years in the early-onset group [21.8% (1 748/8 023) vs 17.5% (2 110/12 068), respectively; P<0.01], the proportion of pregnant women 40-44 years old [6.8% (544/8 023) vs 5.4% (648/12 068), respectively; P<0.01], and the proportion of pregnant women ≥45 years old [0.7% (58/8 023) vs 0.5% (57/12 068), respectively; P=0.021] were significantly higher than those in the late-onset group. (4) Multivariate analysis: advanced age (≥35 years old), multiple pregnancy, irregular antenatal examination or transfer from other hospitals, family history of hypertension (including paternal, maternal and parental lines), previous history of pre-eclampsia, kidney diseases, immune system diseases (systemic lupus erythematosus, antiphospholipid antibody syndrome) and assisted reproductive technology pregnancy were the risk factors affecting the severity of pre-eclampsia (all P<0.05). Conclusion: Pregnant women with high risk factors such as age ≥35 years old, BMI ≥24 kg/m2 before pregnancy, family history of hypertension, history of pre-eclampsia, chronic kidney diseases, immune diseases (mainly including systemic lupus erythematosus and antiphospholipid syndrome) and assisted reproductive technology are more likely to have early-onset pre-eclampsia.

Abstract
Odorant-binding proteins (OBPs) are crucial in insect's olfactory perception, which participate in the initial step of odorant molecules transporting from the external environment to olfactory receptor neurons. To better understand the roles for OBPs in olfactory perception in Cotesia vestalis, a solitary larval endoparasitoid of diamondback moth, Plutella xylostella, we have comprehensively screened the genome of C. vestalis, and obtained 20 CvesOBPs, including 18 classic OBPs and two minus-C OBPs. Motif-pattern analysis indicates that the motifs of C. vestalis OBPs are highly conserved in Hymenoptera. The results of tissue expression analysis show that five OBPs (CvesOBP1/11/12/14/16) are highly expressed in male antennae, whereas six other OBP genes (CvesOBP7/8/13/17/18/19) are significantly transcriptionally enriched in female antennae. The results of RNA interference experiments for three most highly expressed OBP genes (CvesOBP17/18/19) in female antennae demonstrate that they are likely involved in parasitic processes of female wasps, as the wasps take a longer time to target the hosts when they are knocked down.

Abstract
A checklist of all confirmed species of the family Scoliidae (Hymenoptera) from China is made based on the Chinese specimens in the Naturalis Biodiversity Center (RMNH, Leiden) and on additional specimens from the Chinese Academy of Insect Science (IOZ, Beijing), the Zhejiang University (ZJUH, Hangzhou), and the Sun Yat-sen University (SYSUBM, Guangzhou). The Scoliid species from China belong to one subfamily, two tribes, 11 genera and 52 species. Two species are deleted from the fauna of China: Campsomeriella ilanensis (Tsuneki, 1972) and Scolia (Discolia) quadripustulata Fabricius, 1782. One subspecies, i.e., Carinoscolia vittifrons nipponensis Uchida, 1933, status nov., is elevated to species rank. Scolia (Discolia) formosicola Betrem, 1928, status nov. and S. (D.) inouyei Okamoto, 1924 are re-instated valid species.

Abstract
Insects are among the most diverse and successful groups of animals and exhibit great morphological diversity and complexity. The innovation of wings and metamorphosis are some examples of the fascinating biological evolution of insects. Most microRNAs (miRNAs) contribute to canalization by conferring robustness to gene networks and thus increase the heritability of important phenotypes. Though previous studies have demonstrated how miRNAs regulate important phenotypes, little is still known about miRNA evolution in insects. Here, we used both small RNA-seq data and homology searching methods to annotate the miRNA repertoires of 152 arthropod species, including 135 insects and 17 noninsect arthropods. We identified 16,212 miRNA genes, and classified them into highly conserved (62), insect-conserved (90), and lineage-specific (354) miRNA families. The phylogenetic relationship of miRNA binary presence/absence dynamics implies that homoplastic loss of conserved miRNA families tends to occur in far-related morphologically simplified taxa, including scale insects (Coccoidea) and twisted-wing insects (Strepsiptera), leading to inconsistent phylogenetic tree reconstruction. The common ancestor of Insecta shares 62 conserved miRNA families, of which five were rapidly gained in the early winged-insects (Pterygota). We also detected extensive miRNA losses in Paraneoptera that are correlated with morphological reduction, and miRNA gains in early Endopterygota around the time holometabolous metamorphosis appeared. This was followed by abundant miRNA gains in Hymenoptera and Lepidoptera. In summary, we provide a comprehensive data set and a detailed evolutionary analysis of miRNAs in insects. These data will be important for future studies on miRNA functions associated with insect morphological innovation and trait biodiversity.

Abstract
Objective: To explore the HIV-1 drug resistance and subtypes in newly reported HIV/AIDS patients before antiretroviral therapy (ART) in Taizhou city. Methods: A cross-sectional study of HIV-1 drug resistance was conducted among newly reported HIV/AIDS patients before ART in Taizhou from January 2016 to December 2018. HIV-1 pol gene sequences were obtained by RT-PCR. The sequences were submitted to the Stanford University drug resistance database. The drug resistance mutation and the sensitivity of HIV-1 strains to antiretroviral drugs were determined according to WHO Guidelines on HIV drug resistance surveillance of 2014. Results: A total of 806 HIV-1 pol gene sequences were obtained successfully. The overall HIV-1 drug resistance rate was 2.9% (23/806), 1.9% for non-nucleoside reverse transcriptase inhibitors (NNRTIs), 0.6% for nucleoside reverse transcriptase inhibitors (NRTIs), and 0.0% for protease inhibitors (PIs), respectively. From 2016 to 2018, the HIV-1 drug resistance rate was 1.6%, 1.8%, and 4.8%, respectively. The resistance mutations of NNRTIs and NRTIs were mainly K103 N (0.7%) and M184I/V (0.5%). HIV-1 subtypes were mostly CRF01_AE (42.7%,344/806),CRF07_BC (28.9%,233/806) and CRF08_BC (11.2%,90/806).HIV-1 subtypes among homosexually transmitted infections were mostly CRF01_AE (53.3%, 136/255) and CRF07_BC (32.2%, 82/255), and HIV-1 subtypes among heterosexually transmitted infections were mainly CRF01_AE (37.7%, 203/539), CRF07_BC (27.5%, 148/539) and CRF08_BC (16.1%, 87/539). Conclusion: HIV-1 drug resistance rate among newly reported HIV/AIDS patients before ART remained low in Taizhou during 2016 to 2018, an increasing trend seemed to be notifiable and warrants continuous surveillance of HIV-1 drug resistance.

Abstract
BACKGROUND The diamondback moth (DBM), Plutella xylostella (Lepidoptera: Plutellidae), is a notorious pest of cruciferous plants. In temperate areas, annual populations of DBM originate from adult migrants. However, the source populations and migration trajectories of immigrants remain unclear. Here, we investigated migration trajectories of DBM in China using genome-wide single nucleotide polymorphisms (SNPs) genotyped using double-digest RAD (ddRAD) sequencing. We first analyzed patterns of spatial and temporal genetic structure among southern source and northern recipient populations, then inferred migration trajectories into northern regions using discriminant analysis of principal components (DAPC), assignment tests, and spatial kinship patterns. RESULTS Temporal genetic differentiation among populations was low, indicating that sources of recipient populations and migration trajectories are stable. Spatial genetic structure indicated three genetic clusters in the southern source populations. Assignment tests linked northern populations to the Sichuan cluster, and central-eastern populations to the southern and Yunnan clusters, indicating that Sichuan populations are sources of northern immigrants and southern and Yunnan populations are sources of central-eastern populations. First-order (full-sib) and second-order (half-sib) kin pairs were always found within populations, but ~ 35-40% of third-order (cousin) pairs were found in different populations. Closely related individuals in different populations were found at distances of 900-1500 km in ~ 35-40% of cases, while some were separated by > 2000 km. CONCLUSION This study unravels seasonal migration patterns in the DBM. We demonstrate how careful sampling and population genomic analyses can be combined to help understand cryptic migration patterns in insects. © 2020 Society of Chemical Industry.

Abstract
The Scoliidae occur predominantly in tropical and subtropical regions and are ectoparasitoids of Scarabaeoidea larvae (especially of Melolonthinae) which are immobilised, parasitised by the female wasp in their terrestrial larval gallery and buried deeper in a special cell by the female wasp. Herein, we provided, for the first time, illustrated keys to 11 genera and 52 species of Scoliidae from China, based on specimens in the Naturalis Biodiversity Center (RMNH, Leiden) and additional specimens from the Chinese Academy of Insect Science (Beijing), Zhejiang University (ZJUH, Hangzhou) and Sun Yat-sen University (SYSU, Guangzhou) and it is a first attempt to make keys available for all the Scoliidae species in China.

Abstract
Objective: To study the prevalence and correlates of plasma cytomegalovirus (CMV) viremia among newly reported antiretroviral therapy (ART)-naive HIV/AIDS patients in Taizhou during 2017-2018. Methods: CMV DNA was measured in plasma specimens of newly reported ART-naive HIV/AIDS patients by quantitative PCR. Both univariable and multivariable logistic regression analyses were carried out to evaluate CMV viremia correlations among the individuals. Results: Of 612 HIV/AIDS patients, 480 (78.4%) were male, 125 (20.4%) were over 60 years old, 177 (28.9%) were infected via homosexual transmission, and 430 (70.3%) via heterosexual transmission. The prevalence of CMV viremia among HIV/AIDS patients was 13.4% (82/612). Multivariable logistic regression analysis showed that the risk of CMV viremia in CD4+ lymphocyte cells counts (CD4+) ≤200 cells/μl group was higher than CD4 counts >500 cells/μl (OR=5.10, 95%CI:1.74-14.96, P=0.003); The median CMV DNA level (log10) of 82 viremic patients was 1.57 (P25,P75:1.04,2.13); Viremic patients with CD4 counts ≤200 cells/μl had the highest CMV viral load (P<0.01). Conclusions: Among ART-naive HIV/AIDS patients, the prevalence of CMV viremia was significantly associated with immunodeficiency status. Further research is needed to evaluate the association between CMV viremia and the course of HIV infection.

Abstract
Objective: To analyze influencing factors of instant antiretroviral therapy (ART) and explore associution between strategies of ART and immunological effects among HIV/AIDS patients in Taizhou city during 2006-2019. Methods: A retrospective cohort study was conducted on HIV/AIDS patients under ART, and a logistic regression model was used to analyze factors of instant ART. The student t-test and chi-square test were used to compare immunological effect of different ART strategies while the Kaplan-Meier method was used to generate a survival curve. Results: A total of 2 971 HIV/AIDS patients were enrolled with 1 786 cases (60.1%) having instant ART strategy. The proportion of instant ART were 77.8% (1 170/1 504) during 2016 to 2019. The treatment success rate of the instant ART group (87.4%, 1 561/1 786) were higher than the delayed ART group (84.4%, 1 000/1 185). The results of multivariate logistic regression model indicated that male (aOR=1.28, 95%CI: 1.03-1.59), married (aOR=1.71, 95%CI: 1.33-2.19) and baseline CD(4)(+)T lymphocyte cells (CD(4)) counts ≤200 cells/μl (aOR=1.60, 95%CI: 1.27-2.02) were factors positively related to instant ART while 31-40 years old (aOR=0.63, 95%CI: 0.48-0.84), infected through heterosexual transmission(aOR=0.60, 95%CI: 0.49-0.74) and diagnosed before 2015 (aOR=0.20, 95%CI: 0.17-0.23) were inversely related to instant ART. The increase of the CD(4)/CD(8) ratio was greater, and the cumulative ART success rate was higher each year in the instant ART group than in the delayed ART group (P<0.05). Conclusions: The instant ART strategy has been well implemented in Taizhou city during 2006-2019, and the immunological effect was better in instant ART group. The proportion of instant ART were more than 60.0% among HIV/AIDS patients. Instant ART strategy needs to be strengthened for those who are 31-40 years old, women, unmarried, and infected through heterosexual transmission in an attempt to further increase treatment level and improve treatment effect.

Abstract
Objective: To analyze the immunological failure of antiretroviral therapy (ART), its association with baseline anemia and related factors in HIV/AIDS patients in Taizhou prefecture, during 2006-2019. Methods: A retrospective cohort study was conducted among HIV/AIDS patients under ART. Cox regression model was used to analyze predictors of immunological failure and logistic regression model was used to analyze factors of baseline anemia. Results: A total of 2 904 HIV/AIDS patients were enrolled with a median time of 28 (P(25)-P(75):12-53) months follow-up of ART, in which 177 cases (6.1%) were identified as immunological failure with a failure rate of 2.17 per 100 person-years. The cumulative incidence rates of immunological failure in the first, third, fifth, and tenth years were 5.49%, 6.94%, 7.30% and 8.82%, respectively. Results of multivariate logistic regression analysis showed that for the risk of baseline anemia, ≥66 years old group had 4.17 times higher risk than 18-25 years old group (95%CI: 1.68-10.33), males had 0.67 times higher risk than females (95%CI: 0.50-0.89), and CD(4)(+)T cell counts (CD(4))<200 cells/μl group had 4.35 times higher risk than CD(4)≥350 cells/μl group (95%CI: 2.81-6.72), baseline white blood cells<4.0×10(9) cells/L group had 1.73 times higher risk than 4.0×10(9) cells/L-9.9×10(9) cells/L group (95%CI: 1.31-2.29), baseline platelet counts <100×10(9) cells/L and >300×10(9) cells/L groups had 2.02 times and 4.45 times higher risk than 100×10(9) cells/L-299×10(9) cells/L group (95%CI: 1.36-3.01, 95%CI: 3.05-6.50), respectively. WHO classified stage Ⅲ/Ⅳ group had 2.15 times higher risk than WHO classified stageⅠ/Ⅱ group (95%CI: 1.61-2.87), while heterosexual transmission group had 2.03 times higher risk than homosexual transmission group (95%CI: 1.42-2.92). Results of multivariate cox proportional risk regression showed that for the risk of immunological failure, baseline anemia group had 1.77 times higher risk than no anemia group (95%CI: 1.20-2.60), WHO classified stage Ⅲ/Ⅳ group had 1.66 times higher risk than WHO classified stage Ⅰ/Ⅱ group (95%CI: 1.10-2.48), and withdrawal of follow up and death groups had 3.18 times and 4.61 times higher risks than treatment group (95%CI: 1.96-5.19, 95%CI: 2.98-7.13), respectively. Conclusions: The immunological effect of ART among HIV/AIDS patients in Taizhou prefecture was affected by multiple factors, including anemia, clinical stage and follow-up status. Enhancing surveillance of baseline anemia and timely correction of anemia in elder group can help improve treatment outcome of HIV/AIDS patients.

Abstract
Polydnaviruses (PDVs), classified into two genera, bracoviruses (BVs) and ichnoviruses (IVs), are large, double-stranded DNA viruses, which are beneficial symbionts of parasitoid wasps. PDVs do not replicate in their infected lepidopteran hosts. BV circles have been demonstrated to be integrated into host genomic DNA after natural parasitization. However, the integrations of IV circles in vivo remain largely unknown. Here, we analyzed the integration of Diadegma semiclausum ichnovirus (DsIV) in the genomic DNA of parasitized Plutella xylostella hemocytes. We found that DsIV circles are present in host hemocytes with non-integrated and integrated forms. Moreover, DsIV integrates its DNA circles into the host genome by two distinct strategies, conservatively, and randomly. We also found that four conserved-broken circles share similar motifs containing two reverse complementary repeats at their breaking sites, which were host integration motifs (HIMs). We also predicted HIMs of eight circles from other ichnoviruses, indicating that a HIM-mediated specific mechanism was conserved in IV integrations. Investigation of DsIV circle insertion sites of the host genome revealed the enrichment of microhomologies between the host genome and the DsIV circles at integration breakpoints. These findings will deepen our understanding of the infections of PDVs, especially IVs.

Abstract
Phylogenetic trees are essential for studying biology, but their reproducibility under identical parameter settings remains unexplored. Here, we find that 3515 (18.11%) IQ-TREE-inferred and 1813 (9.34%) RAxML-NG-inferred maximum likelihood (ML) gene trees are topologically irreproducible when executing two replicates (Run1 and Run2) for each of 19,414 gene alignments in 15 animal, plant, and fungal phylogenomic datasets. Notably, coalescent-based ASTRAL species phylogenies inferred from Run1 and Run2 sets of individual gene trees are topologically irreproducible for 9/15 phylogenomic datasets, whereas concatenation-based phylogenies inferred twice from the same supermatrix are reproducible. Our simulations further show that irreproducible phylogenies are more likely to be incorrect than reproducible phylogenies. These results suggest that a considerable fraction of single-gene ML trees may be irreproducible. Increasing reproducibility in ML inference will benefit from providing analyses’ log files, which contain typically reported parameters (e.g., program, substitution model, number of tree searches) but also typically unreported ones (e.g., random starting seed number, number of threads, processor type). Replicate runs of maximum likelihood phylogenetic analyses can generate different tree topologies due to differences in parameters, such as random seeds. Here, Shen et al. demonstrate that replicate runs can generate substantially different tree topologies even with identical data and parameters.

Abstract
Objective: To evaluate the changes of left ventricular function in patients with ST segment elevation myocardial infarction (STEMI) before PCI and within 24 hours after PCI by layer-specific strain, and to explore the value of this new assessment method for quantitative monitoring on the myocardial function in STEMI patients. Methods: A total of 40 patients with acute anterior wall myocardial infarction, who underwent PCI in Affiliated Hospital of Jiangsu University during July 2017 to July 2018, were included in this prospective cohort study. According to the symptom to balloon time (STB), the patients were divided into STB ≤6 hours group (26 cases) and STB 6-12 hours group (14 cases). Echocardiography was performed before, immediately, 3 hours and 24 hours after PCI. Echocardiographic indexes including endocardial myocardial longitudinal strain (LS-endo), 18-segment full-thickness myocardial longitudinal strain (LS) of left ventricle and left ventricular global longitudinal strain (GLS) were measured. The mean LS-endo and LS values of myocardial segments in infarcted area (IALS-endo, IALS) and the mean LS-endo and LS values of myocardial segments in non-infarcted area (NIALS-endo, NIALS) were calculated. Results: There were 34 males and 6 females in this cohort and age was (62±10) years. In STB≤6 hours group, the IALS-endo value ((13.7±4.9)% vs. (10.0±2.7)%, P<0.05) and NIALS-endo value ((17.0±2.9)% vs. (14.6±2.9)%, P<0.05) were significantly higher at 24 hours after PCI than those before PCI. In the group of STB 6-12 hours, IALS-endo decreased immediately after PCI ((6.7±3.3)% vs. (11.9±6.5)%, P<0.05), and there was a rising trend at 3 hours after PCI (P>0.05). At 24 hours after PCI, the index was higher than that immediately after PCI ((13.6±8.4)% vs. (6.7±3.3)%, P<0.05). The NIALS-endo value was significantly higher at 24 hours after PCI than that before PCI ((17.1±2.1)% vs. (14.5±3.2)%, P<0.05). In the STB 6-12 hours group, the decrease rate of IALS-endo immediately after PCI was higher than that in the STB ≤6 hours group (93% (13/14) vs. 35% (9/26), P<0.001). In STB ≤6 hours group, the NIALS value at 24 hours after PCI was higher than that before PCI (P<0.05), and there was no significant difference in IALS, NIALS and GLS at other time points (P>0.05). Conclusions: Layered LS is superior to full-thickness LS and GLS in evaluating left ventricular function in STEMI patients. LS measured by echocardiography can continuously and quantitatively evaluate the changes of left ventricular myocardial function in STEMI patients before and after PCI.
