OBJECTIVE To acquire the real-world incidence of ceftazidime-avibactam sodium(CAZ)-related ad-verse reactions of blood system among a large sample of drug medication patients based on the active monitoring system so as to provide reference for safe clinical use of drugs.METHOD With the help of'Adverse Drug Event Active Surveillance and Assessment System-Ⅱ'(ADE-ASAS-Ⅱ),the use of CAZ of the patients who were hospi-talized in Chinese PLA General Hospital from Jan.1,2020 to Dec.31,2023 were retrospectively and automatical-ly monitored,the patients who were alarmed by system were evaluated by two persons,the incidence rates of CAZ-related thrombocytopenia,hemoglobin decreased and leucopenia were calculated,and the related influencing factors were analyzed.RESULTS Among the 278 case-times(191 cases)of patients who were treated with drugs and were enrolled in the study,there were 3(1.08％)case-times of thrombocytopenia,8(2.88％)case-times of hemoglobin decreased and 19(6.83％)case-times of leucopenia;the total incidence of adverse reactions of blood system was 10.79％.Logistic regression analysis showed that age and duration of drug administration were the in-fluencing factors for the CAZ-related adverse reactions of blood system.CONCLUSIONS It is common for the CAZ-related adverse reactions of blood system.The middle-aged and elderly patients who take drug therapy for a long time period are more likely to have the blood system-related adverse reactions.It is necessary to focus on the monitoring of renal function of the patients and adjust the dosage of administration in a timely manner so as to re-duce the incidence of adverse reactions of the blood system.

Multiple myeloma (MM) is a malignant plasmacyte disease that often presents with symptoms such as bone pain and anemia. Currently, there is an increasing number of literature reports on malignant tumors combined with hyperamylasemia, but this is more common in tumors such as gastric cancer, and MM with hyperamylasemia is clinically rare and has not been found in plateau areas. Due to the complex clinical manifestations of MM patients with hyperamylasemia, there is no standard treatment therapy. There is no literature report on the use of daretuumab in combination. Based on the results of the retrospective analysis of the first case of MM with hyperamylasemia in a plateau area, it is recommended that clinicians in plateau areas take amylase level as a sensitive indicator to evaluate the severity of MM in order to reduce the misdiagnosis rate of MM and provide a new treatment option for the promotion and application of MM with hyperamylasemia.

OBJECTIVETo evaluate the value of urine sediment analyzer in the screening of clinically suspected urinary tract infection (UTI) in cancer patients.

METHODSThe results of bacterial count of 1 053 midstream urine samples by UF-1000i urine sediment analyzer (UF-1000i urine sediment analyzer, UF-1000i) were compared with the results of bacterial culture. Moreover, the results of distinguishing bacterial species by the bacterial scattergram were compared with the results of bacteria culture. At the same time, the sensitivity, specificity, positive predictive value and negative predictive value of UF-1000i analyzer for UTI screening were evaluated.

RESULTSOf all the 1 053 samples, the top three bacteria were E. coli, Enterococci and P. aeruginosa. The top three malignant tumors of UTI were bladder, lung cancer and cervical cancers. The positive rate of UF-1000i analyzer was 20% (211/1 053), and that of bacteria culture was 17.9% (188/1 053). There was statistically no significant difference in the positive rates between the two methods (χ(2)=1.636, P>0.05), and the two methods had a considerable consistency (Kappa=0.756). Compared with the clinical diagnosis, UTI screening by UF-1000i analyzer showed a sensitivity of 79.6% (160/201), specificity of 95.5% (814/852), positive predictive value of 80.8% (160/198) and negative predictive value of 95.2%(814/855). The distribution of cocci and bacilli acquired by the bacterial scattergram was basically in accordance with the results of bacterial culture.

CONCLUSIONSBacterial count by UF-1000i analyzer plays an important role in early screening of UTI, and the bacterial scattergram may help to distinguish bacterial species, providing reference for the use of antibiotics in early medication.
