English for General Academic Purposes or English for Specific Purposes? Language Learning Needs of Medical Students at a Chinese University

The debate over the appropriacy of EGAP and ESP has been an ongoing concern in many higher education contexts. In this paper we discuss how teachers’ and students’ perceptions of English curriculum needs are reflected in the conflict between short-term goals, such as passing exams, and long-term goals, such as career development. Students, doctors and teachers at a medical university in the central part of China were asked about their needs through questionnaires and structured interviews. The findings suggest that whilst many felt the need for medical English to be taught in the early years, particularly through medical texts, there was also push back due to the need for general English to pass English exams, such as CET4/6. We argue that through the incorporation of medical texts, students can start to develop their medical English from the first year of university. This not only ensures the motivation for students to study medical English for professional purposes, but also fulfills the perceived need to prepare for the exam.

Integration of Digital Technology into an Early Childhood Teacher Preparation Program in China

The rapid development of technologies has complicated its adoption and integration into early childhood teacher professional development in China. The government of China has developed policies and provided financial support to improve preschools’ ICT infrastructure. Whereas various studies have examined the digital technology development provided to preservice educators around the world, relatively little is known about technology professional supports for early childhood (EC) preservice teachers in China’s universities. In this research, we focus on a university in the central part of China as a case study to explore preservice teachers’ technology use and self-efficacy while engaged in their field-based student teaching experiences. We collected data through an online questionnaire from 55 participants. Despite preservice educators’ positive attitudes toward digital technologies, the results identified several issues that undermined EC preservice teachers’ self efficacy for technology use and limited their instructional practices integrating technology in the field. Nonetheless, with adequate supports, preservice teachers were more likely to develop high confidence in their practice, suggesting the importance of improving and upgrading the current teacher preparation program and opportunities for field-based implementation.

Epidemiology, diagnosis, treatment and control measures of trichinellosis in China: an overview

Trichinellosis is a worldwide zoonotic parasitic disease, which may infect humans and a wide range of animals, including carnivores, herbivores and even birds. Humans get infections through ingestion of raw or semi-cooked meat or meat products containing live Trichinella larvae. Currently, this zoonosis is predominantly prevalent in southwestern, northeastern and central parts of China, which poses a great threat to human health and socioeconomic development. In addition, the emergent public health hazards caused by trichinellosis outbreaks greatly threaten human health and social stability. This review describes the current status, diagnosis, treatment and control measures of trichinellosis in China, so as to provide insights into trichinellosis control in the country.

The case of China’s fiscal decentralization and eco-efficiency: is it worthwhile or just a bootless errand?

During the last two decades, China has made commendable efforts to control environmental pollution and promote sustainable development. Empowering local governments regarding their budgets is an example of such efforts. Although China's fiscal decentralization (FD) stimulated inter-regional economic competition, environmental pollution also came along as a byproduct. Considering these dynamics, this study aims to investigate the association between the FD and the eco-efficiency of 99 prefecture-level cities from China's top ten urban agglomerations from 2003 to 2016. We investigated the issue of cross-sectional dependence among the panel variables and, to check the stationary properties of our data, applied the second generation Pesaran and Cross-sectional augmented Im, Pesaran, and Shin unit root tests. Subsequently, to check the possible impact of FD on eco-efficiency, we applied both Difference Generalized Method of Moments (GMM) and System GMM with the help of several control variables. The results indicated that FD improved eco-efficiency for the overall sample cities; however, this impact varied among different regions of China. The regional analyses confirmed that FD improved eco-efficiency in the eastern and central parts of China, whereas the relationship was negative in the western region. Our results also confirm that irrational use of resources for economic development reduces eco-efficiency. However, sustainable economic development has a positive and significant impact on eco-efficiency. The negative impact of foreign direct investment and secondary industry was also more significant than was that of population density. Our study presents important policy implications for both central and local governments in China, which include an increase in decentralization and eco-efficiency practices and control over foreign investments, lead towards environmental pollution.

Novel SFTSV Phylogeny Reveals New Reassortment Events and Migration Routes.

Severe fever with thrombocytopenia syndrome virus (SFTSV), the causative agent of a febrile human disease, was first identified from central and eastern provinces in China, and later in Japan and South Korea. Hubei Province is one of the major SFTS epidemic areas in the central part of China. This study reported the isolation of 11 new SFTSV strains from patients in Hubei Province collected in 2017. Extensive phylogenetic analyses were conducted based on the complete coding sequences of SFTSV segments including the new strains. It was suggested that five different SFTSV genotypes were circulating in Hubei, and 15 reassortment patterns and migration pathways correlated with each genotype were identified, which was more than previously recognized. Hubei Province was more involved in the evolutionary events of SFTSV than that previously thought in which the evolutionary events of SFTSV were reported to be independent from those in other epidemic regions. Further divergence of SFTSV strains was suggested by pairwise comparison of SFTSV sequences from each genotype and sequence identity normalized to representative strain in genotype C1. Subsequently, amino acid variations specific for genotype(s), strain(s), or cluster(s) were inspected, which may be related to differential biological activity of SFTSV strains/genotypes. In conclusion, we analyzed the current status of SFTSV phylogeny in Hubei Province and discussed the possible events correlated to SFTSV evolution. It provided an in-depth insight into SFTSV evolution, raising concerns for the use of proper SFTSV strains in future studies.

Spatiotemporal Variations of City-Level Carbon Emissions in China during 2000–2017 Using Nighttime Light Data

China is one of the largest carbon emitting countries in the world. Numerous strategies have been considered by the Chinese government to mitigate carbon emissions in recent years. Accurate and timely estimation of spatiotemporal variations of city-level carbon emissions is of vital importance for planning of low-carbon strategies. For an assessment of the spatiotemporal variations of city-level carbon emissions in China during the periods 2000–2017, we used nighttime light data as a proxy from two sources: Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) data and the Suomi National Polar-orbiting Partnership satellite’s Visible Infrared Imaging Radiometer Suite (NPP-VIIRS). The results show that cities with low carbon emissions are located in the western and central parts of China. In contrast, cities with high carbon emissions are mainly located in the Beijing-Tianjin-Hebei region (BTH) and Yangtze River Delta (YRD). Half of the cities of China have been making efforts to reduce carbon emissions since 2012, and regional disparities among cities are steadily decreasing. Two clusters of high-emission cities located in the BTH and YRD followed two different paths of carbon emissions owing to the diverse political status and pillar industries. We conclude that carbon emissions in China have undergone a transformation to decline, but a very slow balancing between the spatial pattern of high-emission versus low-emission regions in China can be presumed.

Origin and evolution of emerging Liao ning Virus (genus Seadornavirus, family Reoviridae)

BackgroundLiao ning virus (LNV) is a member of the genus Seadornavirus, family Reoviridae and has been isolated from kinds of vectors in Asia and Australia. However, there are no systematic studies describe the molecular genetic evolution and migration of LNVs. With the development of bioinformatics, viral genetic data combining the information of virus isolation time and locations could be integrated to infer the virus evolution and spread in nature.MethodsHere, a phylogenetic and phylogeographic analysis using Bayesian Markov chain Monte Carlo simulations was conducted on the LNVs isolated from a variety of vectors during 1990–2014 to identify the evolution and migration patterns of LNVs.ResultsThe results demonstrated that the LNV could be divided into 3 genotypes, of which genotype 1 mainly composed of LNVs isolated from Australia during 1990 to 2014 and the original LNV strain (LNV-NE97–31) isolated from Liaoning province in northern China in 1997, genotype 2 comprised of the isolates all from Xinjiang province in western China and genotype 3 consisted the isolates from Qinghai and Shanxi province of central China. LNVs emerged about 272 years ago and gradually evolved into three lineages in the order genotype 1, genotype 2 and genotype 3. Following phylogeographic analysis, it shows genotype 1 LNVs transmitted from Australia (113°E-153°E,10°S-42°S) to Liaoning province (118°E-125°E,38°N-43°N) in Northeast Asian continent then further spread across the central part of China to western China (75°E-95°E,35°N-50°N).ConclusionLNVs were initially isolated from Liaoning province of China in the Northeast Asia, however, the present study revealed that LNVs were first appeared in Australia in the South Pacific region and transmitted to mainland China then rapidly spread across China and evolved three different genotypes. The above results suggested that LNV had the characteristics of long-distance transmission and there were great genetic diversity existed in the LNV population. Notably, current information of 80 strains of LNVs are limited. It is of great importance to strengthen the surveillance of LNVs to explore its real origin in nature and monitoring of the LNVs’ population variation and maintain vigilance to avoid LNV breaking through the species barrier and further clarify its relationship to human and animal infection.

Understanding the Mosaic of COVID-19: A Review of the Ongoing Crisis.

In late 2019, a queer type of pneumonia emerged in Wuhan city in the central part of China. On investigation, it was found to be caused by the coronavirus. Human coronaviruses were discovered in the 1960s. There are a total of seven types of coronaviruses that infect humans: 229E and NL63 are the alpha coronaviruses; OC43, HKU1, MERS-CoV, and SARS-CoV are beta coronaviruses, and SARS-CoV-2 or COVID-19 is a novel coronavirus. COVID-19 surfaced in China at the culmination of the year 2019. The pandemic then fanned out rapidly, involving Italy, Japan, South Korea, Iran, and the rest of the world.

Assessing the response of sandy‐beach macrobenthos to recreation and the ecological status of the beach ecosystem at Liandao, China

AbstractSandy beaches, prime recreational assets that attract more people than other types of shorelines, are the main assets underpinning many coastal economies and developments. However, the intense stressors to the ecology of sandy beaches caused by recreational activities are generally underestimated or ignored. This study was the first to emphasize the ecological characteristics of recreational beaches in China and assess the response of macrobenthos at Liandao Beach, a typical sandy beach in the central part of China. Using the Before/During/After/Control/Impact (BDACI) method, differences in multiple variables (species richness, mean density, diversity) between a heavily recreationally impacted transect (TrH/Impact) and a less‐impacted transect (TrL/Control) in different impact periods (Before, During & After) were applied to assess the response of sandy‐beach macrobenthos to recreation and tourism. Meanwhile, a comparison between the macrobenthos conditions of the studied beach and reference conditions calculating from historical data of similar beaches with little recreation and tourism disturbances was carried out. Furthermore, the quality control chart approach was used to detect in detail the macrobenthos stable state and yearly response to recreational activities. The results showed that recreation and tourism posed a serious threat to the beach ecosystem; macrobenthos on the studied beach were seriously disturbed by recreational activities, and their variations were highly negatively related to the human recreational level. After monthly recreational impacts, the macrobenthos decreased sharply and recovered with difficulty during 1 year. Over the long‐term, the macrobenthos had a sharp decreasing trend, which indicated that the ecological environment of the beach was highly disturbed. Conservation measures for recreational beaches are very challenging because of the economic value and popularity of sandy beaches as recreational sites. However, practicable conservation measures could be implemented that prevent or slow ecological degradation. A number of management and conservation suggestions are put forward, such as the establishment of the ecological carrying capacity of Liandao Beach in terms of direct recreational use, creation of themed exhibitions related to the beach macrobenthos and beach ecosystem and dissemination of this knowledge to visitors, implementation of spatial zoning of beach use, visitor management and environmental education.

ICT adoption and income diversification among rural households in China

ABSTRACT Although the determinants of income diversification have been widely examined in the literature, little is known about whether and how information and communication technology (ICT) adoption affects household income diversification. To fill in this gap, this paper examines the impact of ICT adoption on income diversification among rural households in China, utilizing open-access data collected through the China Labour-force Dynamics Survey project. We employ a two-stage treatment effects model to address the potential selection bias issue associated with ICT adoption. The empirical results show that ICT adoption exerts a positive and statistically significant impact on income diversification. Further analyses reveal that ICT adoption is more beneficial to low-income rural households and those residing in eastern and central parts of China when it plays a role in diversifying rural income. Our findings suggest that improving rural education and infrastructure such as roads and broadband facilities can help enhance ICT adoption among rural households, which subsequently increases income diversification.

A Spatial Distribution Equilibrium Evaluation of Health Service Resources at Community Grid Scale in Yichang, China

Whether the supplies of health services and related facilities meet the demand is a critical issue when developing healthy cities. The importance of health services and related facilities in public health promotion has been adequately proved. However, since the community population and resource data are usually available at the scale of an administrative region; it is very difficult to perform further fine-scaled spatial distribution equilibrium evaluation studies. Such kinds of activities are highly expected for precise urban planning and management. Yichang is located in Hubei province, the central part of China, along the Yangzi River. It is leading both of China’s smart cities demonstration project and China’s healthy cities pilot project. Yichang has defined 1271 community grids for urban management and service, where each grid consists of 200 households generally with its population distribution data routinely updated. The research set the 15-min walking distances of the residents as impedance factors, and the numbers and the types of health service resources as attractiveness factors for accessibility evaluation. The resource ratio, richness and per capita number of various health service resources that can be reached within 15 min from the community grid building is used as spatial distribution equilibrium evaluation indicators. The entropy weight method is used to assign the indicator weight value. The obtained fine-scale evaluation results were analyzed. In this way, a community grid-scale spatial distribution equilibrium evaluation of health service resources in Yichang was performed. The proposed research could be of value for rapid and precise evaluation of spatial distribution equilibrium evaluation of a variety of healthy city resources, to support healthy city planning and management.

Evaluating national ecological risk of agricultural pesticides from 2004 to 2017 in China

In recent years, excessive application and loss of pesticides have caused great risks to the aquatic systems, but the spatio-temporal variability in the ecological risk that agricultural pesticides pose to aquatic systems has not been explored at the national scale. In this study, an integrated assessment framework was proposed for the potential ecological risk of surface water caused by agricultural pesticide loss. The spatio-temporal variability in the potential ecological risk caused by agricultural pesticide runoff was evaluated. Based on the results, the total pesticide emissions increased from 165.47 tons in 2004 to 179.77 tons in 2017. Among the three pesticide types, insecticide had the largest application, but its runoff was estimated as the lowest. High-risk areas of insecticide runoff were concentrated in the east, south and central part of China, while the central region of China was identified as a hotspot due to the high and the ever-increasing ecological risk. This study provides an integrated method for potential ecological risk assessment of agricultural pesticide runoff to adjacent water bodies in large-scale regions and the results of the study have direct implications for environmental policies on pesticide management in China and around the world.

Spatiotemporal Analysis of Influenza in China, 2005\u20132018

Influenza is a major cause of morbidity and mortality worldwide, as well as in China. Knowledge of the spatial and temporal characteristics of influenza is important in evaluating and developing disease control programs. This study aims to describe an accurate spatiotemporal pattern of influenza at the prefecture level and explore the risk factors associated with influenza incidence risk in mainland China from 2005 to 2018. The incidence data of influenza were obtained from the Chinese Notifiable Infectious Disease Reporting System (CNIDRS). The Besag York Mollié (BYM) model was extended to include temporal and space-time interaction terms. The parameters for this extended Bayesian spatiotemporal model were estimated through integrated nested Laplace approximations (INLA) using the package R-INLA in R. A total of 702,226 influenza cases were reported in mainland China in CNIDRS from 2005–2018. The yearly reported incidence rate of influenza increased 15.6 times over the study period, from 3.51 in 2005 to 55.09 in 2008 per 100,000 populations. The temporal term in the spatiotemporal model showed that much of the increase occurred during the last 3 years of the study period. The risk factor analysis showed that the decreased number of influenza vaccines for sale, the new update of the influenza surveillance protocol, the increase in the rate of influenza A (H1N1)pdm09 among all processed specimens from influenza-like illness (ILI) patients, and the increase in the latitude and longitude of geographic location were associated with an increase in the influenza incidence risk. After the adjusting for fixed covariate effects and time random effects, the map of the spatial structured term shows that high-risk areas clustered in the central part of China and the lowest-risk areas in the east and west. Large space-time variations in influenza have been found since 2009. In conclusion, an increasing trend of influenza was observed from 2005 to 2018. The insufficient flu vaccine supplements, the newly emerging influenza A (H1N1)pdm09 and expansion of influenza surveillance efforts might be the major causes of the dramatic changes in outbreak and spatio-temporal epidemic patterns. Clusters of prefectures with high relative risks of influenza were identified in the central part of China. Future research with more risk factors at both national and local levels is necessary to explain the changing spatiotemporal patterns of influenza in China.

Identification and assessment of pathogenicity of a naturally reassorted infectious bursal disease virus from Henan, China

Infectious bursal disease virus (IBDV) is still a vital etiological agent in poultry farms. IBDV outbreaks occasionally occur due to the presence of very virulent, reassortment or variant strains. Vaccine immunization has played crucial roles in IBD control for decades. However, survival pressure of IBDV from the vaccine immunization also increases the reassortments of circulating viruses. In this study, an IBDV strain was isolated from several broiler farms in Henan Province, central part of China, and named IBDV HN strain. Based on the results of RT-PCR, sequencing and phylogenic analyses of VP1 and VP2 genes, the IBDV HN strain is a novel reassortment strain in the Henan region. Segment A of this strain appears to originate from the very virulent IBDV strain, while segment B comes from the other field reassortment strains. This may be the result of natural reassortant of virus circulating in the field. About 60% (6/10) of experimentally infected specific pathogen-free chickens died after 3 to 5 d post-infection with typical symptom and pathological lesions. The IBDV HN strain was prone to horizontal transmission, which poses a serious threat to the chicken industry. Further investigation on the prevalence, virulence, and evolution of HN strain IBDV will provide a foundation for the prevention and control of the disease in this region.

Temporal Changes in China’s Air Temperature Distribution and Its Impact on Hot Extreme Occurrence

The likelihood of experiencing hot extremes has drastically increased due to global warming. Using 554 ground-based air temperature stations, changes in the number of hot days (NHD) in the Chinese mainland during 1960 to 2011 was investigated. We found that the NHD of the current period (1991–2011) was 70% higher than that of the base period (1960–1990). This NHD increment was attributed to the increased summer air temperature mean and its extended hot tail length—defined as the range of the mean and 90th percentile of summer air temperature. To distinguish the relative contribution of air temperature mean and hot tail length change to the NHD occurrence, a numerical-based frame work was proposed. Results showed that global warming (mean temperature increase) contributes approximately 75% of the total NHD increment. Although the average contribution of the hot tail length change is relatively small, it dominates the NHD change in regions where global warming is insignificant, e.g., the central part of China. Results suggest that frameworks and models that fail to capture the air temperature tail changes will result in biased low hot extreme occurrence estimations. This low bias would be particularly significant in regions where the mean temperature change is marginal. Hence, capturing the tail change should be the key model evaluation criterion in regions where the annual mean temperature change is relatively insignificant.

Sulfate formation during heavy winter haze events and the potential contribution from heterogeneous SO<sub>2</sub> + NO<sub>2</sub> reactions in the Yangtze River Delta region, China

Abstract. Rapid sulfate formation is recognized as a key characteristic of severe winter haze in China. However, air quality models tend to underestimate sulfate formation during heavy haze periods, and heterogeneous formation pathways have been proposed as promising mechanisms to reduce gaps between observation and model simulation. In this study, we implemented a reactive SO2 uptake mechanism through the SO2+NO2 heterogeneous reactions in the Comprehensive Air Quality Model with Extensions (CAMx) to improve simulation of sulfate formation in the Yangtze River Delta (YRD) region. Parameterization of the SO2+NO2 heterogeneous reactions is based on observations in Beijing and considered both the impact of relative humidity and aerosol pH on sulfate formation. Ammonia is reported to be critical for the formation of secondary inorganic aerosols. Estimation of ammonia emissions is usually associated with large uncertainties and models tend to underestimate ammonia concentrations substantially. Sensitivity tests were conducted to evaluate the influence of the SO2+NO2 heterogeneous reactions as well as ammonia emissions on modeled sulfate concentrations during a period with several heavy haze episodes in the YRD region. Base case model results show large underestimation of sulfate concentrations by 36 % under polluted conditions in the YRD region. Adding the SO2+NO2 heterogeneous reactions or doubling ammonia emissions alone leads to slight model improvement (∼6 %) on simulated sulfate concentrations in the YRD region. However, model performance significantly improved when both the SO2+NO2 heterogeneous reactions and doubled ammonia emissions were included in the simulation: predicted sulfate concentrations during polluted periods increased from 23.1 µg m−3 in the base scenario to 29.1 µg m−3 (representing an increase of 26 %). Aerosol pH is crucial for the SO2+NO2 heterogeneous reactions, and our calculated aerosol pH is always acidic and increased by 0.7 with doubled ammonia emissions. Modeling results also show that this reactive SO2 uptake mechanism enhanced sulfate simulations by 1 to 5 µg m−3 for the majority of the eastern and central parts of China, with more than 20 µg m−3 increase in sulfate concentrations over the northeastern plain. These findings suggest that the SO2+NO2 heterogeneous reactions could be potentially important for sulfate formation in the YRD region as well as other parts of China. Further studies are needed to constrain the uncertainties associated with the parameterization of the SO2+NO2 heterogeneous reactions based on local data as well as to evaluate this mechanism in other regions. In addition, ammonia emissions were found to be a key driving variable of the spatial patterns of sulfate enhancement due to the new pathway. Substantial efforts are needed to improve the accuracy of the ammonia emission inventory.

The effect of structured empathy education on empathy competency of undergraduate nursing interns: A quasi-experimental study

BackgroundEmpathy is a crucial element in fostering a positive relationship between nurses and patients. Recent research indicates that the degree of empathy in nursing students declines as they gain education or experience. A number of teaching strategies have been used to improve nursing students' empathy competence levels. However, little is currently known about how empathy is best taught or enhanced in senior nursing students in China. ObjectivesTo implement a structured empathy educational program as developed from the Delphi technique, as well as to evaluate its effects on empathy competence among undergraduate nursing interns. DesignThis study is quasi-experimental, with two-group comparison. ParticipantsUndergraduate nursing students in their fourth year (n = 118) were recruited from an affiliated teaching hospital in Wuhan, Central Part of China, between January 2018 and March 2018. MethodsA convenience sample of 118 undergraduate nursing interns were recruited from a teaching hospital in Wuhan and assigned to either the intervention or the control group according to their preference. Participants in the intervention group had received a 2-week, 12-hour structured empathy-related educational program (two sessions per week, 3 h per session), whereas the control group received no intervention. The Jefferson Scale of Empathy-Health Providers (JSE-HPs) was used to assess students' empathy levels before and after the intervention. ResultsAn independent samples t-test revealed that scores of empathy competence levels in the intervention group were significantly higher than those in the control group following the intervention. Three domains of empathy competence level were also significantly higher in the intervention group after the two weeks' training relative to the control group, namely: perspective taking, compassionate care, and standing in the patient's shoes. ConclusionsThis modified empathy educational program may prove beneficial in improving the empathy competence level of undergraduate nursing interns.

Tourist’s Perception on the Service Quality of Sheqi Ancient Town: A Demographic Perspective

The main purpose of this study is to identify tourists’ perception on the quality of tourism services of an ancient town, Sheqi, in central part of China from demographic perspective. A survey of 1,389 tourists visited an ancient town in center part of China was conducted as the basis for analysis. Descriptive analysis, T test and one-way ANOVA are employed to profile the status quo of tourists’ perceived quality and examine the differences between different groups of tourists with different demographic characteristics regarding gender, ages, monthly income, occupations, and highest levels of education. The results showed that tourists have a high perception and evaluation on the quality of tourism service in Sheqi ancient town, and tourists with different age, monthly income, and education level have different perception on the tourism service significantly. Keywords: Perceived Quality; SERVQUAL Model; Demographics; Sheqi Ancient Town DOI : 10.7176/JTHS/44-04 Publication date :October 31 st 2019

The relationship between family environmental factors and child sensory integration

Objective: To investigate the relationship between child sensory integration and family environmental factors.Methods: This was a cross-sectional study. The sample (n = 130) was recruited from children attending the outpatient department of a pediatric hospital located in central part of China. Sensory integration of the child was reported by either parent from using a Chinese version of the Sensory Integration and Praxis Test.Results: Approximately 17.69%-24% of the participating children experienced impairments in different dimensions of sensory integration. Severe impairment occurred in 3%-5% of the participating children. Paternal-child interaction had a significant effect on vestibular function of the child, after controlling for the effect of covariates including maternal obstetric history and low birth weight status of the child. Family functioning was found significantly related to tactile sensation, proprioception. and learning ability of the children.Conclusions: It appears that family environment plays a significant role in sensory integration outcomes of older children.

Distribution and Determinants of Dermatophagoides Mites Sensitization ofAllergic Rhinitis and Allergic Asthma in China

Background: The implementation of allergen immunotherapy (AIT) requires extensive knowledge of allergen distribution in the region to identify high-risk regions for AIT utilization. However, the geographical distribution patterns of the major Dermatophagoides allergens in China remain unclear despite the increasing prevalence of these allergens. Methods: We performed comprehensive database searches of articles demonstrating the distribution patterns of Dermatophagoides-sensitized allergic rhinitis (AR) and allergic asthma (AA) in China, published between 1990 and 2017. Results: We retrieved 163 articles encompassing 114,302 allergen-positive cases to generate the distribution maps. The rate of sensitization to Dermatophagoides pteronyssinus(D. pteronyssinus)and Dermatophagoides farinae (D. farinae) was similar in patients with AR (75.1 vs. 75.2%, p > 0.05) but not in those with AA (78.5 vs. 77.7%, p = 0.041). Patients with AR and AA shared similar regional distribution patterns of both D. pteronyssinus and D. farinae sensitization, which were highest in the southern and central parts of China and lowest in the northern regions, especially in the Northwest. The overall rate of sensitization to D. pteronyssinus and D. farinae was significantly higher in patients with AA (p < 0.001). Additionally, the annual mean temperature and humidity were the 2 major determinants of D. pteronyssinus and D. farinae sensitization in AR and of D. pteronyssinus sensitization in AA, whereas the annual mean temperature was the sole determinant for D. farinae sensitization in AA. Conclusion: These findings may inform clinicians of the strategies for the prevention of Dermatophagoides sensitization and may be of benefit to the future clinical management of allergic diseasesassociated with sensitization to Dermatophagoides mites.
