Few studies have been carried out to systematically screen regional temperature-sensitive diseases. This study was aimed at systematically and comprehensively screening both high- and low-temperature-sensitive diseases by using mortality data from 17 study sites in China located in temperate and subtropical climate zones. The distributed lag nonlinear model (DLNM) was applied to quantify the association between extreme temperature and mortality to screen temperature-sensitive diseases from 18 kinds of diseases of eight disease systems. The attributable fractions (AFs) of sensitive diseases were calculated to assess the mortality burden attributable to high and low temperatures. A total of 1,380,713 records of all-cause deaths were involved. The results indicate that injuries, nervous, circulatory and respiratory diseases are sensitive to heat, with the attributable fraction accounting for 6.5%, 4.2%, 3.9% and 1.85%, respectively. Respiratory and circulatory diseases are sensitive to cold temperature, with the attributable fraction accounting for 13.3% and 11.8%, respectively. Most of the high- and low-temperature-sensitive diseases seem to have higher relative risk in study sites located in subtropical zones than in temperate zones. However, the attributable fractions for mortality of heat-related injuries were higher in temperate zones. The results of this research provide epidemiological evidence of the relative burden of mortality across two climate zones in China.

The recent development of technologies of the laboratory systems in microbiology, providing detailed genome sequencing, has paved the ways for isolating new pathogens and carrying out in-depth study of long-known microorganisms. Moreover, the progressing of science and technology contributes to study changes in the ecology of microorganisms and the epidemiological characteristics of their spreading over the world. These advances enable scientists to find out some "new" diseases, known as emergent infectious diseases. Emergent diseases have emerged as a new type of rapidly evolving, long-known infectious diseases. A prime example of an emergent infection is the Zika virus (ZIKV). ZIKV belongs to the family Flaviviridae of the Flavivirus genus. It was first isolated from the blood of a rhesus macaque in 1947 in East Africa (Uganda), in the Zika forest, where its name came from. A year later, in the same area, ZIKV was detected in mosquitoes of the Aedes africanus genus. For a long time following the initial isolation of ZIKV, isolated sporadic cases of the disease caused by this pathogen were recorded in Asia and Africa. In 2007, an ZIKV outbreak was reported on the island of YAP (Micronesia). This was the first outbreak outside Asia and Africa. Zika virus is primarily transmitted by the bite of an infected mosquito from the Aedes genus in tropical and subtropical regions. But according to literature data, this virus can be spread by 17 species of mosquitoes of this genus. AE. aegypti and Ae. Albopictus have been known a leading role of spreading the infection. Considering that these mosquitoes are not only carriers of ZIKV, but also some other flavivirusiv representatives, their wide geographical distribution has become an issue of great concern. AE. aegypti mosquitoes are thermophilic and live only in tropical and subtropical climate zones and this fact has played as significant rope in the ZIKV spread. Ae. albopictus mosquitoes promote the circulation of this pathogen and cause a rapid expansion of the virus in the world, since this species has become widely distributed in countries of subtropical and temperate climate zones. To date, besides the main vector-borne transmission of the virus, there are a number of reports about ZIKV transplacental transmission from an infected mother to the foetus. ZIKV caused viral infection during the pregnancy results in microcephaly, a congenital condition associated with incomplete brain development and abnormally small size of the skull. This viral infection can also lead to such complications as miscarriage, stillbirth, and premature birth. According to the literature, there is the connection between ZIKV and not congenital CNS abnormalities, but also with Guillain-Barre syndrome. There have been publications on not only ZIKV mosquito transmission and transplacental transmission, but a few reports on ZIKV sexual transmission when no barrier contraceptives are used. ZIKV can be isolated from ejaculate within 14-28 days from the onset of the first symptoms of the disease.

We investigated the effects of cold and hot seasons on hospital admissions for acute myocardial infarction (AMI) at the junction of tropical and subtropical climate zones. The hospitalization data of 6897 AMI patients from January 1997 to December 2011 were obtained from the database of the National Health Insurance, including date of admission, gender, age, and comorbidities of hypertension, diabetes mellitus (DM), and dyslipidemia. A comparison of AMI prevalence between seasons and the association of season-related AMI occurrences with individual variables were assessed. AMI hospitalizations in the cold season (cold-season-AMIs) were significantly greater than those in the hot season (OR 1.15; 95% CI 1.10–1.21). In the subtropical region, cold-season-AMIs were strongly and significantly associated with the ≥65 years group (OR1.28; 95% CI 1.11 to 1.48). In the tropical region, cold-season-AMIs, in association with dyslipidemia relative to non-dyslipidemia, were significantly strong in the non-DM group (OR 1.45; 95% CI 1.01 to 2.09) but weak in the DM group (OR 0.74; 95% CI 0.55 to 0.99). The cold season shows increased risks for AMI, markedly among the ≥65 years cohort in the subtropical region, and among the patients diagnosed with either DM or dyslipidemia but not both in the tropical region. Age and comorbidity of metabolic dysfunction influence the season-related incidences of AMI in different climatic regions.

To create shadows and enhance ventilation, piloti is commonly used in subtropical climate areas, and the influence of piloti on outdoor environment need to be revealed. Taking the city of Guangzhou China, as an example, by adopting coupled simulation method, this work researched on the influence of piloti on wind environment in residential blocks. Firstly, a series of building cases with piloti in the center of each building was simulated, and the piloti of each case is 0%, 40%, 60%, 80% and 100%. Secondly, another 3 cases with 50 percent piloti ratio were simulated, and the piloti arrangement method is crossed, vertical and horizontal for each case. The results showed that, when piloti is in the center of each building, both of velocity under piloti and out of piloti area showed positive correlation with piloti ratio, and the inflection point is 60 percent and 80 percent independently. The result of another 3 cases was plotted on the figure of piloti centralized cases, and for the velocity out of piloti area, the value of these 3 cases is very close to each other and much lower than the centralized case. For the velocity under piloti area, the vertical piloti arrangement case fits the trend of centralized cases well, and the horizontal and cross piloti arrangement case is much lower than that of centralized cases.
