Objective:To observe the effects of electroacupuncture(EA)on learning and memory ability and nucle-ar factor E2 related factor 2(Nrf2),glutathione peroxidase 4(GPX4),NAD(P)H-quinone oxidoreductase 1(NQO1),reactive oxygen species(ROS)in hippocampus of neonatal rats with hypoxic-ischemic brain damage(HIBI)and its anti-oxidative stress mechanism.Methods:A total of 76 neonatal rats were randomly divided into Sham opera-tion group(Sham),HIBI model group(HIBI),electroacupuncture group(HIBI+EA),and Nrf2 inhibitor ML385 group(HIBI+EA+ML385).The neonatal rat model of HIBI was established by classical Rice method.The HIBI+EA group was treated with electroacupuncture for 30 min/d for 14 consecutive days.In the HIBI+EA+ML385 group,30 mg/kg ML385 was intraperitoneally injected at 1 h before each electroacupuncture intervention.Morris water maze test was performed on 21 days after modeling to test the learning and memory ability of neonatal rats in each group.Nissl staining and HE staining were used to observe the morphology of neurons in the hippocampal CA1 region,and DHE flu-orescent probe was used to detect the expression of ROS in the hippocampal CA1 region.The contents of Nrf2,GPX4 and NQO1 in hippocampus were detected by Western blot.Results:Compared with the Sham group,the HIBI group had severe pathological damage,a prolonged escape latency,a decreased number of platform crossings,a significantly increased expression of ROS,and a significantly decreased expression of Nrf2,GPX4,and NQO1(P<0.05).Com-pared with HIBI group,the pathological damage was significantly attenuated,the escape latency was shortened,the number of platform crossings was increased,the expression of ROS was decreased,and the expression of Nrf2,GPX4 and NQO1 was increased in HIBI+EA group(P<0.05).Compared with HIBI+EA group,the pathological damage was aggravated,the escape latency was prolonged,the number of crossing the platform was decreased,the expression of ROS was increased,and the expression of Nrf2,GPX4,and NQO1 was decreased in HIBI+EA+ML385 group(P<0.05).Conclusion:Electroacupuncture can effectively improve the learning and memory ability of hypoxic-ischemic neonatal rats,which is related to its effect in reducing oxidative stress in hippocampal neurons by regulating Nrf2 signa-ling pathway.

Objective To analyze the clinical and pathogenic characteristics,as well as influencing factors for the prognosis of patients with Candida bloodstream infection(CBSI).Methods Clinical data of 47 CBSI patients in a hospital from January 2015 to September 2024 were collected.Distribution of departments and infection strains,an-timicrobial resistance,and influencing factors for the poor prognosis of patients were analyzed.Results A total of 51 strains of Candida were detected from 47 CBSI patients,mainly from the intensive care unit(ICU;n=25,53.2％),department of intestinal fistula surgery(n=8,17.0％),and department of respiratory medicine(n=4,8.6％),et al.The main detected pathogens were Candida albicans(n=29,56.9％),Candida tropicalis(n=7,13.7％),Candida glabrata(n=6,11.8％),and Candida parapsilosis(n=6,11.8％).Resistance rate of Candida albi-cans to fluconazole was 11.5％(3/26).According to the prognosis results,patients were divided into a good prog-nosis group(n=26,55.3％)and a poor prognosis group(n=21,44.7％).Univariate analysis showed statistically significant differences between patients in the good prognosis group and the poor prognosis group in terms of abso-lute neutrophil count,ICU admission,mechanical ventilation,tracheal intubation,gastrointestinal hemorrhage/per-foration,and surgical treatment(lesion clearance,drainage or unblocking for obstruction)(all P＜0.05).Prelimi-nary multivariate logistic regression analysis showed that gastrointestinal hemorrhage/perforation was a potential risk factor for the poor prognosis in CBSI patients(OR=11.156,95％CI:1.434-86.809,P=0.021).Conclusion The detected CBSI strains are mainly Candida albicans,and gastrointestinal hemorrhage/perforation may be one of the potential risk factors affecting the prognosis of CBSI patients.These patients are generally in critical condition and should be detected and treated as early as possible to improve their prognosis.Due to the small amount of speci-mens,further research is still needed for confirmation.
