Examines the formation of China's political system from 1948 to 1954. Discussion on the political stalinization of the Eastern bloc countries; Role of Mao Zedong in drafting the constitution; Overview of the constitution of 1954.

The article presents a case study of a 12-year-old Chinese boy with abrupt onset limb dystonia. He was genotyped in the Pantothenate kinase 2 (PANK2) gene and was detected with two heterozygous PANK2 mutations The presence of Pantothenate kinase-associated neurodegeneration (PKAN) associated with PANK2 mutations. The article also discusses the prevalence of PKAN associated with PANK2 mutations in China.

In order to well understand the physicochemical characteristics and biological activities of polysaccharides (OPPs) from different cultivars of okra collected in China, the chemical characteristics, rheological properties, antioxidant activities, in vitro binding properties, and in vitro inhibitory effects on α-glucosidase of polysaccharides from five representative okra cultivars, including 'Lvjian', 'Kalong8', 'Shuiguo', 'Taiwanwufu', and 'Kalong3', were investigated and compared. Results showed that the constituent monosaccharides of OPPs were similar, which composed of rhamnose, galacturonic acid, galactose, and arabinose. However, their weight-average molecular weights varied from 2.76 × 103 to 4.20 × 103 kDa, and from 0.11 × 103 to 0.90 × 103 kDa, respectively. The uronic acids and degrees of esterification of OPPs ranged from 39.32% to 61.68%, and from 21.66% to 30.02%, respectively. OPPs exhibited typical shear-thinning behavior and viscoelastic properties. Furthermore, OPPs exhibited remarkable antioxidant activities, in vitro binding capacities, and inhibitory effects on α-glucosidase, which might be attributed to their relatively high content of uronic acids, high degrees of esterification, and high molecular weights. Results are helpful for better understanding of the physicochemical structures and bioactivities of OPPs, and OPPs had good application prospects as functional food ingredients for industrial applications. • Structural and rheological properties of OPPs were influenced by different okra cultivars. • OPPs exhibited remarkable antioxidant activities. • OPPs also exhibited remarkable binding capacities and inhibitory effects on α-glucosidase. • OPPs have potential to be explored as functional food ingredients for industrial applications.
