Sunshine duration and solar radiation contributed to severe Bell's palsy: An 11-year time series analysis based on a distributed lag non-linear model model.

Although previous studies have suggested that meteorological factors are associated with Bell's palsy, articles on this topic are rare and the results are inconsistent. We aim to reveal the relationship between exposure to different meteorological factors and the onset of severe Bell's palsy (SBP) with daily data. A case-crossover study based on time-series data was applied, and the minimum risk value of each climatic factor was set as the reference value. We fitted a distributed lag non-linear model (DLNM) which applied quasi-Poisson regression to evaluate the exposure-response association and the lag-response association of meteorological factors on the occurrence of SBP. The mode value and per-decile interval value of each meteorological factor were all included in the analysis. Sensitivity analyses were conducted to test the robustness of results. A total of 863 SBP patients (474 males and 389 females) from 7 hospitals in the Shenzhen Futian District were selected from January 2009 to February 2020. The highest relations effect was tested in the cumulative exposure-response result shown as follows; mean temperature at the minimum value 15.3°C with RR of 10.370 (1.557-69.077) over lag 0 to 13; relative humidity at the 30th value 71% with RR of 8.041 (1.016-63.616) over lag 0 to 14; wind speed at the 90th value 31 (0.1 m/s) with RR of 1.286 (1.038-1.593) over lag 0; mean air pressure at the 30th value 1001.4 (pa) with RR of 9.052 (1.039-78.858) over lag 0 to 5; visibility at the 80th value 26.5 (km) with RR of 1.961 (1.005-1.423) over lag 0 to 2; average total cloud cover at the max value 100 (%) with RR 1.787 (1.014-3.148) over lag 0 to 2; sunshine duration at the 10th value 0.1 (h) with RR of 4.772 (1.018-22.361); daily evaporation shows no relationship in the cumulative result; daily average solar radiation at the minimum value 0 (W/m2) with RR of 5.588 (1.184-26.382). There is a relationship between wind speed and the onset of SBP, while mean air pressure, visibility, and average total cloud cover, especially sunshine duration and solar radiation which showed a strong effect, may be associated with severe clinical symptoms of SBP. Mean temperature and relative humidity may affect the course of SBP.

Analysis of genotype and age distribution of cervical human papillomavirus infection in Futian District, Shenzhen, China

Our study aims to understand the prevalence of cervical HPV (Human papilloma virus) infection, different subtypes causing infection and age distribution characteristics of women in Futian District, Shenzhen, China, to provide a reference for effective local prevention and treatment of HPV and targeted development and application of the HPV vaccine. Information on HPV results, age and HPV genotypes infected were collected and retrospectively analysed among women who attended the free cervical cancer screening programme conducted by the Shenzhen Futian District Government between 01 January 2016 and 31 December 2022 at our gynaecology outpatient clinics and medical check-up centres. There were 2792 positive cases among 27,738 females in Futian District, Shenzhen, with a positivity rate of 10.07%. Types 52, 58, 16, 68, 51, 39, 18, 31 and 33 were the top 9 infected genotypes in Futian District, Shenzhen, China. The high prevalence of these three genotypes, HR-HPV (High-risk human papilloma virus) types 68, 51 and 39, in the region is an important finding. Age-related differences in HPV infection rates were considerable, with the bimodal peak of the infection rate curve occurring in the age ranges of 30–34 and 60–65. The distribution of cervical HPV infection types in each region is unique, and different age groups have their susceptibility to different HPV genotypes. Geographical and age specificity should be considered in the therapeutic usage of vaccinations.

Spatiotemporal Patterns of the Use of Green Space by White-Collar Workers in Chinese Cities: A Study in Shenzhen

White-collar workers, with tremendous work pressure, excessive working hours, and poor physical condition, need green spaces not only to have physical exercise and social gatherings, but also to become closer to nature and to relieve stress for their mental health. In China, the 996 office schedule, working from 09:00 to 17:00 six days a week, has become popular in the workplace; under such high-intensity work and pressure, white-collar workers have limited time to access green space for leisure, and their use of green space for health benefits is compromised. This study selected Shenzhen Futian Central Business District to find out the green space use patterns and preferences of white-collar workers based on GPS data and questionnaire surveys. In addition, the value of green exposure in the time dimension was calculated according to individuals’ actual behaviors. Based on cluster analysis, this study summarized the typical green space use patterns of three groups of white-collar workers, which reflects the hidden inequity of white-collar groups who are subjected to varying degrees of spatiotemporal constraints in using green space. This paper puts forward three directions for the optimization of green space allocation, functional facilities, and improved walkability in employment-intensive urban areas. The results provide certain guiding significance for alleviating the mismatch of time and space in green space enjoyment and for improving the spatiotemporal inclusiveness of green spaces in urban central business districts.

Sunlight Pollution Analysis of Glass Curtain Wall in 3D City

Objectives Sunlight pollution caused by glass curtain walls of buildings in urban environment has brought great threats to traffic safety, fire control and residents?? health. At present, most researches on architecture sunlight pollution traditionally focus a local small range at specific construction based on simula-tion or measurement methods. We keep the way of three-dimensional (3D) computation, dissimilarly inte-grates geographic resources to expand the perception range of city sunlight pollution brought by building glasses. Methods The calculation technique of sunlight pollution builds 3D spatial relationship among road, building facade and sunlight in real urban environment, using deep-learning image segmentation to extract glass curtain walls. Then, combined with glare evaluation model, we develop an innovative sunlight pollu-tion model from perspective of drivers to evaluate the suitability for people. Results Taking Shenzhen Fu-tian Center as an example, the multi-level analyses of sunlight pollution are implemented by means of calcu-lation under real time and real location, and path selection based on evaluation. Through these instances, the time sequence regularity, the spatial distribution characteristics and the path estimation of architecture sunlight pollution are revealed. Conclusions The analyses retain space computation mode with innova-tions, fully utilize street view resources, and provide people the macroscopic concept, which indicates rela-tive strength of building sunlight pollution. Additionally, the method ensures instantaneity of urban sunlight pollution acquisition and computation, to a certain extent covers shortages of current researches, and is fur-ther capable of reference evaluation in environment protection, accurate warnings and predictions of glare intensity for pedestrians and drivers.

Carbon isotope ratio of leaf litter correlates with litter production in a mangrove ecosystem in South China

As an important ecological process, litter production is generally recognized as being directly relevant to net primary productivity and carbon storage of mangrove ecosystems. In the present study, we made continuous, monthly assessment of litter production from 2010 to 2016 for five mangrove sites in Shenzhen Futian Mangrove Nature Reserve. Results showed that all mangrove locations displayed distinct seasonality in litter production, and that the alien species produced significantly more litters than the native species. Carbon isotope analysis revealed an interesting, strongly negative relationship between litter production and δ13C of leaf litter (δ13CLL) among the five studied sites. Although it has long been known that δ13C of plant leaves correlates with water use efficiency and some components of plant productivity, the observed δ13CLL-litter production linkage is novel, justifying future exploration of δ13CLL as an potential indicator of litter production and net primary productivity in mangrove ecosystems.

An LCA-based environmental impact assessment model for regulatory planning

Assessing the environmental impact (EI) of regulatory planning (a lower tier in the Chinese urban planning system) has significant implications for improving the environmental performance of the future built environment. Current environmental impact assessments generally focus on microscale and macroscale, while mesoscale studies at region level are lacking. To fill this gap, this paper proposes an LCA-based environmental impact assessment model for regulatory planning, which focuses on embodied EI of urban construction and operational EI associated with the operation of the built environment. To ensure the regulatory plans both meet the environmental limits and fit well with environmental policy requirements, this paper also presents a new impact analysis method by integrating environmental carrying capacity analysis and distance to target method. The Statutory Plan of Shenzhen Futian Free Trade Zone 03-T2 is used as a case study to test and demonstrate the applying process and functions of the proposed method. Results indicate that the proposed model can effectively quantify the future environmental impact associated with a regional development plan, and can potentially be used as a tool for urban administrators to make decisions on regulatory planning revision and provide references for environmental management.

Research on compactness ratio model of urban underground space and compact development mechanism of rail transit station affected area

In order to assess the impact of underground space development on urban compactness, taking Shenzhen Futian Station and Tokyo Station as empirical cases, this paper uses the comprehensive compactness formula to extract influencing factors and to explore the interaction mechanism between underground space utilization and urban compact development. Previous studies have shown that when urban development reaches a certain threshold, the area compactness will be improved. Otherwise, when the development is below the threshold, the area compactness will be reduced. The compactness we discuss in this study is related to the efficiency of underground space development. The average building distance is a core factor affecting urban compactness and the efficiency of underground space development. Increasing total building area of underground space development of rail stations can significantly increase urban compactness.

First Report of Black Spot of Acanthus ilicifolius Caused by Fusarium solani in China.

Acanthus ilicifolius (family Acanthaceae) grows mainly in tropical coastal areas and is an important medicinal plant that can be used to treat asthma, rheumatism, etc. In July 2013, symptoms of black spots on the leaves of A. ilicifolius were observed in the Mangrove Conservation Area of Shenzhen Futian (22°32' N, 114°03' E) and Leizhou peninsula (20°12'~21°35' N, 109°30'~110°55' E), Guangdong Province, China. Initial symptoms of the disease were a small, dark brown spots (4 to 5 × 4 to 6 mm) surrounded by a yellow halo (1 to 2 mm in diameter), that would later extend to round or irregular black spots. Leaves eventually turned chlorotic and plants defoliated. Tissues from symptomatic leaves were excised, surface sterilized with 75% ethanol solution (v/v) for 20 s, soaked in 0.1% HgCl2 solution for 45 s, rinsed three times in sterile water, cut into small pieces (2 to 3 mm), plated on potato dextrose agar (PDA), and incubated 3 to 5 days at 28°C without light. Four isolates named from LSL-1 to LSL-4 with different morphological characteristics were obtained. To fulfill Koch's postulates, wounded and non-wounded leaves were inoculated. Fresh wounds were made with a sterile needle on detached leaves and on living plants. Mycelial plugs of each isolate were applied and covered with a piece of wet cotton to maintain moisture. For the control, the healthy leaves were inoculated with PDA plugs. All treatments were incubated at room temperature. Black spots were observed on the wounded leaves inoculated with isolate LSL-1 after 3 days, while the other three isolates and the control remained symptomless, and the pathogen similar to LSL-1 was re-isolated from the diseased leaves. Non-wounded leaves didn't become infected. The pathogenic test was repeated three times with the same conditions, and it was confirmed that LSL-1 was the pathogen causing the black spot of A. ilicifolius. Identification of the pathogen was conducted using morphological and molecular characteristics. Hyphal tips of LSL-1 were transferred to PDA medium in petri dishes for morphological observation. Two types of conidia were observed. The macroconidia were cylindrical to slightly curved, falciform shaped, with two to four septa, and measured 39 to 45 × 4.7 to 5.0 μm. The microconidia were oval to kidney shaped, single celled, 8 to 10 × 2.5 to 3.5 μm. Chlamydospores were also observed, produced singly or in pairs. Based on morphology (1,4), the isolate was tentatively identified as Fusarium solani. For molecular identification, the internal transcribed spacer (ITS) of ribosomal DNA, beta-tubulin gene, and translation elongation factor 1-alpha (EF-1α) gene was amplified using the ITS1/ITS4 (5), ITS4/ITS5 (5), T1/T2 (2) and EF1/EF2 (3) primer pairs. The gene sequences were deposited in GenBank (KJ720639 for the ITS1/ITS4 region, KF826493 for the ITS4/ITS5 region, KJ720638 for the beta-tubulin, and KF826492 for EF-1α region) and showed 99% identity to the F. solani strains (AY633746 for ITS1/ITS4 region, AM412637 for ITS4/ITS5 region, KF255996 for beta-tubulin region, DQ246859 for EF-1α region). According to these results, the pathogen of black spot of A. ilicifolius was identified as F. solani. To the best of our knowledge, this is the first report of F. solani causing black spot of A. ilicifolius in China.

基于可达性的绿色交通发展环境评估研究

绿色交通发展模式是国内大多数城市认可并极力倡导的，不少城市制定了绿色交通发展目标，但是没有一种很好的方法去评估绿色交通发展的环境。针对城市中的日常出行活动，提出以城市建筑物为研究对象，通过城市活动场所、公交站点以及公交线路三个方面的累计机会可达性来评估城市绿色交通发展环境的方法。以深圳福田区为例，收集福田区建筑、服务设施，道路网络及公共交通线路信息，建立GIS模型并选取11个社区，评估社区之间的绿色出行环境差别，并对社区的道路网络，建筑密度及服务设施密度进行了分析比较，希望能对今后城市发展中绿色交通规划和建设工作提供参考。Green traffic development model is most recognized and strongly advocated by domestic cities. Many cities have made green traffic development plans and goals, but there are no good methods to assess their green traffic development situations. For urban non-commute traffic, this paper presents a method that integrated city building’s walk accessibility of service facilities, walk ac-cessibility of bus stop and public traffic accessibility to evaluate urban green traffic development environment. We build a GIS model of Shenzhen Futian and the model includes the information of Futian buildings, service facilities, road network and bus lines. Bases on the model, the paper ana-lyzes the differences of green traffic development environment of 11 communities and finds that road network density, building density and service facility are key factors to promote low carbon travel. The results can be helpful for urban land planning and green traffic planning.

Differences in leaf construction cost between alien and native mangrove species in Futian, Shenzhen, China: Implications for invasiveness of alien species

Construction cost (CC) is a quantifiable measure of energy demand for biomass production, and low CC is hypothesized to give an alien plant growth advantages and increase its potential to be an invader. Comparison of leaf CC and growth traits between alien and native mangroves in Shenzhen Futian Nature Reserve showed CC per unit mass (CCmass), carbon concentration and gross and ash-free caloric values of alien mangroves were significantly lower than those of native species, while the height and chest circumference were just the opposite. Alien species Sonneratia apetala had the lowest CCmass while Sonneratia caseolaris had the lowest CCarea, and were 8.99% and 32.17% lower than those of native species, respectively. Conversely, specific leaf area (SLA) of these two Sonneratia species was significantly higher than native species. Lower CC and higher SLA make the two Sonneratia species grow and spread faster than other mangroves and enhance their invasive potential.
