Abstract

In order to evaluate the water quality changes of Dahai Lake in Inner Mongolia, the water quality monitoring data of Dahai Lake from 2008 to 2021 were used as an example, and the improved Nemero pollution index method and the principal component analysis method were used to evaluate the water quality changes of Dahai Lake. The results show that the two evaluation methods of Daihai Lake evaluation of water quality change trend results are basically the same, are able to fully reflect the comprehensive level of water quality pollution, but each evaluation method has disadvantages, the improved Nemero pollution index method can not reflect the contribution of each pollutant, the principal component analysis method can not evaluate the water quality category. Therefore, the combination of two methods, the improved Nemero pollution index method and the principal component analysis method, can complement and support each other's evaluation conclusions, and the evaluation results are more accurate and objective, and can reflect the changes in the water quality of Daihai Lake in a comprehensive manner.

Abstract

Cigarette smoking is known to induce serious lung diseases, but there is not an effective method to solve this problem. The present study investigated vitamin D3 on over-expression of CXCR3 and CXCL10 in mice induced by cigarette smoking. A pulmonary airway model was designed, and morphological assessment of emphysema, IL-4, IFN-γ and CXCL10 concentration in bronchoalveolar lavage fluids, expression of CXCR3 and CXCL10 were detected. Emphysema of the mice only exposed to cigarette smoke was significant, and concentration of IL-4, IFN-γ and CXCL10 was also increased. In addition, CXCR3 and CXCL10 were over-expressed. The degree of emphysema, concentration of IL-4, IFN-γ and CXCL10, and expression of CXCR3 and CXCL10 in mice administrated with low dose vitamin D3 were similar to the normally treated mice. Low dose of vitamin D3 can effectively protect the lung from the damage induced by cigarette smoke.

Abstract

Stroke is a common neurological disease. Post-stroke sensory disorder is one of the common complications of stroke， which has severe negative impact on motor function and activity participation of patients. Transcranial direct current stimulation （tDCS）， a technique that uses 1 to 2 mA of direct current to modulate the cerebral cortex， is non-invasive， safe and well tolerated by patients. This study elaborates on the theoretical basis and mechanism of action of tDCS in treating post-stroke sensory disturbances， and analyzes and summarizes the application of tDCS in post-stroke sensory disturbances， confirming the effectiveness of tDCS， providing strong support for further clinical research of tDCS in the field of post-stroke rehabilitation.
