BEIJING - Yang Chongyong, a former senior legislator in northern China's Hebei province, has been charged with bribery, the Supreme People's Procuratorate (SPP) said Monday.The indictment paper has been delivered to the Second Intermediate People's Court of Tianjin municipality, by the Second People's Procuratorate of Tianjin.Yang is accused of taking advantage of his former posts of a member of the standing committee of the Communist Party of China (CPC) of Hebei province and vice governor of Hebei province, to seek benefits for others and accepting "a huge amount" in bribes, according to the SPP.Under the directive of the SPP, the People's Procuratorate of Tianjin transferred Yang's case to the Second People's Procuratorate of Tianjin after completing the investigation.The prosecutors have informed Yang of his litigation rights, interrogated him, and listened to his lawyer's opinions, the SPP said.Yang had been vice head of the Hebei Provincial People's Congress Standing Committee since 2016. Prior to that, he had served as vice governor of Hebei for eight years.Investigators alleged that Yang used fake identity documents for outbound trips without permission, concealed changes in his marital status, and confronted investigations, according to a statement from the CPC Central Commission for Discipline Inspection published in July 2017.Yang also borrowed vehicles and apartments from private entrepreneurs for a lengthy period of time, the statement said.Yang, a senior official, has severely violated the Party's code of conduct and "polluted the political ecology of Hebei province," it said. rheumatoid arthritis silicone braceletssilicone braceletsrubber band bracelets picturesmake custom wristbandsfree rubber bracelets
BEIJING - Nanozymes, nanomaterials with intrinsic enzyme-like activities, have been widely used in cancer diagnosis in recent years, but controlling their performance in treating a target tumor cell remains a challenge.A research team, jointly led by Yan Xiyun from the Institute of Biophysics under the Chinese Academy of Sciences and Gao Lizeng from Yangzhou University, has for the first time developed a strategy to coordinate nanozymes to target tumor cells and selectively kill tumors. Their findings were published in Nature Communications last week.During tumor growth and development, elevated levels of hydrogen peroxide (H2O2) are often exhibited in solid tumors, which render tumor cells more resistant to therapeutic treatment.This situation reduces the effect of chemotherapy. If the accumulated H2O2 can be combined with oxygen to be converted into a toxic reactive oxygen species, this may enable more effective means of tumor therapy, according to Yan.Previously natural enzymes were used, however, they were less sensitive and not as stable, so enzyme mimics or artificial enzymes were developed, but the efficiency of enzyme mimics was often insufficient.Therefore, the team has developed a nanozyme which has shown excellent bio-compatibility.To optimize its performance for tumor therapy, scientists used ferritin, an intracellular protein found in most human tissue, to modify the surface of the nanozymes to enable them to target tumors.Tests demonstrated that ferritin-modified nanozymes suppressed tumors in animal models, and proved the feasibility of using nanozymes for tumor therapy."If modified, nanozymes can function as Trojan horses, transporting cell-destroying compounds into tumor cells," said Yan.Nanozymes can be fine-tuned via size, dosage, and surface modification. In addition, they have multiple functions, high stability, and are easy to scale up at a low cost, according to the study."We hope this nanozyme-based tumor therapy can enable new strategies for cancer treatment," Yan said.
