Article Synopsis
- Heilongjiang reclamation area is essential for China's grain production and food security, making drought risk assessment crucial for effective disaster management strategies.
- The study uses a comprehensive system of 17 indicators to evaluate agricultural drought risk and employs advanced algorithms, notably the sparrow algorithm-based improved particle swarm optimization (SSAPSO), for better optimization results.
- Results indicate a general decline in agricultural drought risk over time, with increased exposure and resistance capacity, while the western region faces higher drought risks due to greater hazards and vulnerabilities compared to the eastern region.
Previous studies have shown that Zhichan powder elevated immunity and suppressed oxidation in mice. Rat models of Parkinson's disease were induced by stereotaxically injecting 6-hydroxydopamine into the substantia nigra. The rat models were intragastrically treated with Zhichan powder, which is composed of milkvetch root, ginseng, bunge swallowwort root, himalayan teasel root, Magnolia officinalis, Ligustrum lucidum Ait.

Reverse transcription PCR results showed that tyrosine hydroxylase mRNA expression in the rat substantia nigra was significantly increased, while monoamine oxidase B mRNA expression was significantly decreased in the Zhichan powder group, compared with the model group. In addition, the levels of striatal dopamine and homovanillic acid, the ratio of dopamine to homovanillic acid, and the activity of blood superoxide dismutase were all higher in the Zhichan powder group than in the model group, but the content of malondialdehyde in blood was lower.

Objective: To investigate the know gene types of main wild type measles virus strains and take measures to control measles in Jilin Province.
Methods: Genetic characterization of 9 measles viruses isolated from 72 throat swabs or urine specimens of measles patients using CDW(150) cells line was studied in Jilin Province in 2005.
Results: Sequence analysis of 450 nucleotides of COOH-terminal of nucleoprotein (N) genes of 9 isolates indicated that all were members of H(1) genotype, in which there are 7 strains of H1a and 2 strains of H1b, the H1a subgroup differed from H1b by 2.
