Age-related macular degeneration (AMD) is a disease that affects the vision of elderly individuals worldwide. Although current therapeutics have shown effectiveness against AMD, some patients may remain unresponsive and continue to experience disease progression. Therefore, in-depth knowledge of the mechanism underlying AMD pathogenesis is urgently required to identify potential drug targets for AMD treatment. Recently, studies have suggested that dysfunction of mitochondria can lead to the aggregation of reactive oxygen species (ROS) and activation of the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) innate immunity pathways, ultimately resulting in sterile inflammation and cell death in various cells, such as cardiomyocytes and macrophages. Therefore, combining strategies targeting mitochondrial dysfunction and inflammatory mediators may hold great potential in facilitating AMD management. Notably, emerging evidence indicates that natural products targeting mitochondrial quality control (MQC) and the cGAS/STING innate immunity pathways exhibit promise in treating AMD. Here, we summarize phytochemicals that could directly or indirectly influence the MQC and the cGAS/STING innate immunity pathways, as well as their interconnected mediators, which have the potential to mitigate oxidative stress and suppress excessive inflammatory responses, thereby hoping to offer new insights into therapeutic interventions for AMD treatment.

Objective To understand the respiratory protection competency of staff in hospitals.Methods Staff from six hospitals of different levels and characteristics in Beijing were selected,including doctors,nurses,medical technicians,and servicers,to conduct knowledge assessment on respiratory protection competency.According to exposure risks of respiratory infectious diseases,based on actual cases and daily work scenarios,content of respira-tory protection competency assessment was designed from three aspects:identification of respiratory infectious di-seases,transmission routes and corresponding protection requirements,as well as correct selection and use of masks.The assessment included 6,6,and 8 knowledge points respectively,with 20 knowledge points in total,all of which were choice questions.For multiple-choice questions,full marks,partial marks,and no mark were given respective-ly if all options were correct,partial options were correct and without incorrect options,and partial options were correct but with incorrect options.Difficulty and discrimination analyses on question of each knowledge point was conducted based on classical test theory.Results The respiratory protection competency knowledge assessment for 326 staff members at different risk levels in 6 hospitals showed that concerning the 20 knowledge points,more than 60％participants got full marks for 6 points,while the proportion of full marks for other questions was relatively low.Less than 10％participants got full marks for the following 5 knowledge points:types of airborne diseases,types of droplet-borne diseases,conventional measures for the prevention and control of healthcare-associated infec-tion with respiratory infectious diseases,indications for wearing respirators,and indications for wearing medical protective masks.Among the 20 knowledge questions,5,1,and 14 questions were relatively easy,medium,and difficult,respectively;6,1,4,and 9 questions were with discrimination levels of ≥0.4,0.30-0.39,0.20-0.29,and ≤0.19,respectively.Conclusion There is still much room for hospital staff to improve their respiratory protection competency,especially in the recognition of diseases with different transmission routes and the indications for wearing different types of masks.

OBJECTIVE: To investigate the safety and the short-term efficacy of venetoclax combined with azacitidine followed by cladribine (VAC regimen) in children with refractory/ relapsed acute myeloid leukemia (AML). METHODS: The clinical data, treatment outcomes, complications, and blood product consumption of 6 children with refractory/relapsed AML treated with VAC regimen in the Children's Hospital of Soochow University from August 2021 to December 2021 were retrospectively analyzed. RESULTS: Among the 6 children, there were 1 male and 5 females. 5 cases were refractory AML, and 1 case was relapsed AML, which recurred again 16 months after allogeneic hematopoietic stem cell transplantation. 4 children were accompanied by chromosomes or genes that predicted poor prognosis, such as RUNX1, FLT3-ITD, KMT2A exon 2-exon 8 dup, MLL-AF6, 7q-, KMT2A exon 2-exon 10 dup, etc. After received VAC regimen, 4 cases achieved CR+CRi, 1 case achieved PR (only MRD did not relieve, MRD was 0.59%), and 1 case was NR (but the proportion of bone marrow blasts decreased). All 6 patients had grade Ⅳ neutropenia, and 4 patients had grade Ⅳ thrombocytopenia. During the period of neutropenia, none of the 6 children developed symptoms of infection such as fever, cough, and diarrhea. No treatment-related death occurred. CONCLUSION Venetoclax combined with azacitidine followed by cladribine provides a new treatment option for patients with relapsed/refractory AML who have poor efficacy in early induction remission theragy, showing good efficacy and safety.

ObjectiveTo explore the mechanism of Wutou Chishizhi Wan in regulating autophagy and phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/glycogen synthase kinase-3β （GSK-3β） signaling pathway in rats with myocardial ischemia-reperfusion injury （MIRI）. MethodSixty male SD rats were randomly assigned into the normal group （normal saline）， model group （normal saline）， positive control （trimetazidine， 5.4 mg·kg^-1） group， and low-， medium-， and high-dose （1.63， 4.9， 14.7 g·kg^-1， respectively） Wutou Chishizhi Wan groups， with 10 rats in each group. The rats in other groups except the normal group underwent left anterior descending coronary artery ligation for modeling. Electrocardiogram was employed to detect the ST-segment elevation to evaluate the modeling. Hematoxylin-eosin （HE） staining was performed to reveal the damage of myocardial tissue. The levels of aspartate aminotransferase （AST） and creatine kinase （CK） were determined by colorimetry， and those of cardiac troponin T （cTnT） and myoglobin （MYO） by enzyme-linked immunosorbent assay （ELISA）. Western blot was carried out to determine the protein levels of microtubule-associated proteins 1 light chain 3 （LC3）， autophagy-related gene Beclin-1， PI3K， Akt， GSK-3β， p-GSK-3β， and p-Akt. ResultCompared with the normal group， the modeling elevated the serum levels of AST， CK， cTnT， and MYO （P<0.01）， destroyed the arrangement of myocardial cells abd nucle， twisted and broken myocardial fibers， up-regulated the protein levels of LC3Ⅱ/Ⅰ and Beclin-1 （P<0.01）， and down-regulated the protein levels of PI3K， p-Akt， and p-GSK-3β （P<0.01）. Compared with the model group， trimetazidine and Wutou Chishizhi Wan （all the doses） lowered the levels of AST， CK， cTnT， and MYO in serum （P<0.01）， restored the arrangement of myocardial cells and muscle fibers， reduced necrosis， down-regulated the protein level of Beclin-1 （P<0.01）， and up-regulated the protein levels of PI3K， p-Akt， and p-GSK-3β （P<0.01）. Additionally， Wutou Chishizhi Wan （all the doses） down-regulated the protein level of LC3Ⅱ/Ⅰ （P<0.05， P<0.01）. Compared with those in the trimetazidine group， the serum AST level rose in the low-dose Wutou Chishizhi Wan group （P<0.05） and declined in the high-dose group （P<0.01）， and the protein level of Beclin-1 was down-regulated in the medium-dose group （P<0.01）. Additionally， the trimetazidine group had higher protein level of LC3Ⅱ/Ⅰ than medium- and high-dose Wutou Chishizhi Wan groups （P<0.05， P<0.01）， higher protein level of PI3K than low-， medium-， and high-dose groups （P<0.01）， lower protein level of p-Akt than low- and medium-dose groups （P<0.01）， and higher p-GSK-3β protein level than the medium-dose group （P<0.01）. ConclusionDifferent doses of Wutou Chishizhi Wan can ameliorate MIRI， and the high dose has the best effect. Wutou Chishizhi Wan can reduce the activity of myocardial injury markers AST， CK， cTnT， and MYO， and alleviate the pathological damage of myocardial tissue. It can down-regulate the protein levels of beclin-1， LC3Ⅱ/Ⅰ， and up-regulate those of PI3K， p-Akt， and p-GSK-3β. In summary， Wutou Chishizhi Wan may inhibit excessive autophagy and regulate the PI3K/Akt/GSK-3β signaling pathway to exert protective effect on MIRI rats.
