[Analysis of Spatiotemporal Variation and Driving Factors of Water Quality in the Xiangjiang River Basin from 1990 to 2016].

In order to explore the spatiotemporal variation characteristics and driving mechanism of water quality in the Xiangjiang River Basin, the data of 16 water quality parameters at 113 stations over 26 years from 1990 to 2016 in the Xiangjiang River Basin were collected for synthetically assessing the water quality and identifying its main pollutants through the water quality index and other methods. The causal mechanism of water quality, especially the driving effect of water level and land use pattern, was analyzed. The results showed that： ① The overall water quality grade of the Xiangjiang River Basin during the study period was "good.

[Sustainability science revisited: Recent advances and new opportunities].

During the past decade, sustainability science has rapidly developed into a globally well-recognized and important new science of the 21st century. However, sustainability science has not received much attention from scientists and practitioners in China where sustainable development and ecological civilization have been prominent themes. To promote the development of sustainability science in China, Wu, et al.

[Dynamics of habitat suitability for waterfowls from 1990 to 2015 in the ecological function zone of Sanjiang Plain, Northeast China].

As a wetland of international importance, the ecological function zone of the Sanjiang Plain (EFZSP) plays an important role in maintaining waterfowl habitat. With the increasing disturbance of human beings, land use and climate changes, habitat suitability for waterfowls (HSW) has drawn greater attention of ecologists. In this study, Landsat TM/ETM+/OLI and HJ-1B images in 1990, 2000, 2010 and 2015 were used to obtain land cover classification by object-based image analysis, and the entropy and analytic hierarchy process methods were adopted to determine the factors and their weights, the factors selected in this study included water condition (lake and river density), disturbance factor (residence and road density), shelter condition (land cover type and slope), and food abundance (NDVI).

[Imaging characteristics of different types of cerebral cysticercosis].

Objective: To study the imaging characteristics of different types of cerebral cysticercosis.

Methods: The CT and MRI findings of 166 patients with clinical diagnostic cerebral cysticercosis were reviewed retrospectively.

Results: Among the 166 cerebral cysticercosis patients, there were 108 cerebral parenchyma type cases, 15 ventricles type cases, 3 meningeal type cases, and 40 mixed type cases according to the cysticerci being in the parts of the brain.

[Dipylidium caninum infection in an infant: one case report].

This paper reports the diagnosis and therapy of one case of Dipylidium caninum infection in an infant.

[Comparative study on EEG and neuroimaging of patients with cerebral cysticercosis before and after treatment].

Objective: To study the changes of cerebral function and pathological morphology before and after the antiparasitic treatment with albendazole and praziquantel in patients with cerebral cysticercosis.

Methods: The data of EEG and neuroimaging of 412 patients with cerebral cysticercosis were retrospectively analyzed.

Results: Before the treatment, the mild abnormality, moderate abnormality, and severe abnormality were observed in 40.

[Ecological compensation standard in Dongting Lake region of returning cropland to lake based on emergy analysis].

The annual emergy and currency value of the main ecological service value of returning cropland to lake in Dongting Lake region from 1999 to 2010 was calculated based on emergy analysis. The calculation method of ecological compensation standard was established by calculating annual total emergy of ecological service function increment since the starting year of returning cropland to lake, and the annual ecological compensation standard and compensation area were analyzed from 1999 to 2010. The results indicated that ecological compensation standard from 1999 to 2010 was 40.

[Clinical analysis of 91 cases of imported falciparum malaria from Africa].

Objective: To explore the clinical characteristics, early diagnosis, and treatment of patients with imported falciparum malaria from Africa.

Methods: The clinical data of 91 imported falciparum malaria cases were analyzed by retrospective study.

Results: All the 91 cases had the history of mosquito bites.

[Dynamic changes of vegetation net primary productivity in permafrost zone of Northeast China in 1982-2009 in response to global change].

As one of the high-latitude cold regions, the permafrost zone of Northeast China (PZNC) is more sensitive to global change. Based on the AVHRR GIMMS NDVI and MODIS NDVI, and by using CASA model, this paper simulated the net primary productivity (NPP) in the PZNC from 1982 to 2009. In 1982-2009, the mean annual air temperature, annual solar radiation and sunshine duration, and atmospheric CO2 concentration and its annual increasing rate in the PZNC increased significantly while the annual precipitation had a significant decrease, and the annual NPP showed an up-and-down trend, with the turning point in 1998.
