In thiswork,the perovskite LaZnO_(3) was synthesized via sol-gel method and applied for photocatalytic treatment of sulfamethizole(SMZ)antibiotics under visible light *** was almost completely degraded(99.2%±0.3%)within 4 hr by photocatalyst LaZnO3 at the optimal dosage of 1.1 g/L,with amineralization proportion of 58.7%±0.4%.The efficient performance of LaZnO_(3) can be attributed to itswide-range light absorption and the appropriate energy band edge levels,which facilitate the formation of active agents such as·O_(2)^(−),h^(+),and·*** integration of RP-HPLC/Q-TOF-MS and DFT-based computational techniques revealed three degradation pathways of SMZ,which were initiated by the deamination reaction at the aniline ring,the breakdown of the sulfonamidemoieties,and a process known as Smile-type rearrangement and SO2 *** toxicity of SMZ and the intermediateswere analyzed by quantitative structure activity relationship(QSAR),indicating the effectiveness of LaZnO_(3)-based photocatalysis in preventing secondary pollution of the intermediates to the ecosystem during the degradation *** visible-light-activated photocatalyst LaZnO_(3) exhibited efficient performance in the occurrence of inorganic anions and maintained high durability across multiple recycling tests,making it a promising candidate for practical antibiotic treatment.

Open Journal of Emergency Medicine 2024年第2期12卷 29-32页

作者： nguyen Dang Duc nguyen Phuong Sinh lam nguyen Hong Anh Poison Control Center of Bach Mai Hospital Hanoi Vietnam Thai nguyen Medicine and Pharmacy University Thai Nguyen Vietnam

Cyanide poisoning is one of the most dangerous poisonings, and it can be absorbed into the body through the mouth, inhalation and through the skin. A 32-year-old female patient was admitted to our poison control center because of high fever, severe vomiting, and seizures. Physical examination found that the patient was drowsy, had a high fever of 40 degrees Celsius, pulse of 140 beats/minute, and increased tendon and bone reflexes. Exploiting the patient’s information, it was discovered that the patient bought Cyanide to drink with the intention of committing suicide. The patient was quickly treated with gastric lavage and activated charcoal. Echocardiography recorded EF: 35%, reduced movement of the entire myocardium. CK blood test: 4562 U/L. The patient’s condition rapidly deteriorated and the patient was made ECMO, IHD and CVVHDF. After 3 days of treatment, the patient’s condition did not improve, so the family asked for the patient to go home. This article aims to describe the rapidly progressing and severe damage to the heart and muscles of patients with cyanide poisoning.

Currently,there are no harmonized guidelines which govern skin banking in the Asia Pacific ***,skin banks are either unregulated or rely on their nation’s legislation or international accreditation to uphold their quality standards.A new set of skin banking guidelines was devel-oped through a comprehensive review and collation of best international practices for the Asia Pacific Burn Association(APBA)members,from donor screening and testing,to skin recovery,processing,storage and distribution,and quality *** regulatory requirements reviewed include the European directives,Australia’s Therapeutic Goods Administration and Sin-gapore’s tissue banking *** technical and quality management recommendations are referenced from the American Association of Tissue Banks(AATB),the United States Food and Drug Administration standards and guidance documents,various relevant European guides,Japanese Society of Tissue Transplantation guidelines and the Asia Pacific Association of Surgical Tissue *** mainly from the AATB standards,the new Asia Pacific Burn Association Guidelines for Skin Banking in Therapeutic Applications offer a comprehensive manual,address-ing:governance and contracts;staff responsibilities;quality management;facilities,equipment and supplies management;donor consent and testing;and recommendations of good practices pertaining to skin recovery,processing,storage and *** complementing current generic regulations,they provide technical specifications of major aspects unaddressed in most *** inaugural set of new regional skin banking guidelines would be a start for regional members of the APBA to adopt,and will hopefully culminate in a set of standards so that,in the long run,skin allografts from this region can be of similar quality,which can simplify import process and facilitate the exchange of allografts between members.
