Inhibition of Delayed Cerebral Ischemia by Magnesium Is Insufficient for Subarachnoid Hemorrhage Patients: A Network Meta-Analysis.

Objective: After subarachnoid hemorrhage, magnesium could reduce the incidence of delayed cerebral ischemia; however, it is still controversial. This study updated the results of recently published magnesium-related studies and conducted an exploratory analysis of the impact of application strategies and intervention factors on the results.

Methods: Public databases were searched from the date of their inception to May 10, 2021.

Effects of exogenous vitamin D on endoplasmic reticulum stress-related factors in the vitamin D deficiency rats with cerebral ischemia.

We observed the potential neuroprotective effect of exogenous vitamin D on cerebral ischemia in vitamin D deficiency rats and explored its mechanism. Sixty Sprague Dawley rats were randomly divided into three groups including control (CON) group, vitamin D deficiency (VDD) group and vitamin D deficiency combined with exogenous vitamin D (VDD + VD) group, with 20 rats in each group. The rats in the CON group were fed with normal diet, while the rats in the VDD and VDD + VD groups with vitamin D-deficient diet for 8 weeks, and then underwent middle cerebral artery occlusion (MCAO).

[Assessment of rice achievable productivity and its application in rice production management division: a case study in Fuyang County of Zhejiang Province, East China].

Rice productivity is the key factor affecting rice production and its sustainable development. Based on the gradation of cultivated land quality at county-level, this paper evaluated the rice productivity in Fuyang County of Zhejiang Province, and, through selected sampling field investigation and according to the land productivity index of paddy field quality, a model for assessing rice achievable productivity was established, aimed to analyze the regional rice productivity and its achievable productivity. In the study area, there was a positive correlation between the land productivity index and rice yield.
