In practical applications,relative humidity in the air is a key factor affecting the photocatalytic removal of NO,which is often overlooked in previous ***,we developed a direct Z-scheme UiO-66-NH_(2)/Bi_(2)moO_(6)heterojunction with a nanoflower-like structure to systematically investigate the effect of relative humidity on photocatalytic removal of *** optimized heterojunction for the removal efficiency of NO was 71.6%at1.07 mg·m^(-3)NO concentration(relative humidity=10%),and the generation of NO_(2) was only 1.1%.Interestingly,with the increase in relative humidity,it showed a higher inhibition effect on NO_(2),while the removal of NO decreased slightly(8%),which might be attributed to the affinity effect of NO_(2) with water molecules and the competitive adsorption of H_(2)O and NO on the surface of the heterojunction ***,the reaction pathways of NO removal at the developed heterojunctions were revealed by in situ DRIFTS *** work provides a novel vision for the development of direct Z-scheme heterojunction photocatalysts to effectively remove NO and inhibit the formation of toxic intermediate NO_(2) under different humidities.

Takotsubo cardiomyopathy is a heart condition that is widely known to be caused by stress. It presents with symptoms that are similar to a myocardial infarction even though the coronary arteries are clear. This case report details the clinical characteristics, diagnostic assessment, and management plan of a 55-year-old male patient with a past medical history of alcoholism who arrived at the emergency department with the typical symptoms of acute pancreatitis. The case demonstrates the progression of Takotsubo cardiomyopathy, which was triggered by acute pancreatitis in the context of alcoholism, and underlines the significance of early detection and management to enhance the patient’s outcomes.

AIm: To evaluate the effect of scleral encircling bands on the development and progression of diabetic retinopathy(DR) in diabetic ***: The medical records of diabetic patients who underwent unilateral retinal detachment(RD) surgery using scleral buckle and encircling band were reviewed retrospectively. Both eyes of patients were included in the study: one eye in each patient had a scleral buckle with encircling band(the operated eye) and the other one is the non-operated eye. The demographic characters, duration of diabetes and period between surgery and the last recall visit were retrieved from each patient. All the cases underwent fundus photo and fluorescein angiography(when indicated) to confirm the DR ***: Totally 25 patients fulfilled the inclusion and the exclusion criteria were become eligible for the study. A total of 50 eyes of 25 patients were enrolled in this analysis. The mean period of time passed from surgery with encircling band and the last reassessment visit was 12.5±2 y. Even though DR could develop in the operated eyes, it was at a less degree of severity compared to the non-operated eyes of same patients(P=0.027).CONCLUSION: Scleral encircling bands have protective effects against the development and progression of DR.
