Objective:To observe the efficacy of thrombectomy combined with ezetimibe and atorvastatin in patients with acute ischemic stroke (AIS) and the serum levels of absent in melanoma 2 (AIM2) and leukotriene B4 (LTB4).Methods:A prospective study method was used to select 60 patients with AIS thrombectomy treated in Marina Bay Central Hospital of Dongguan City from June 2021 to December 2022, and they were divided into two groups according to random number table method, with 30 cases in each group. The control group was given atorvastatin treatment, and the study group was combined with ezetimibe treatment on the basis of the control group treatment. Blood routine indexes, blood lipid indexes and serum levels of AIM2 and LTB4 were compared between the two groups at admission, discharge and follow-up for 3 months. The National Institutes of Health Stroke Scale (NIHSS) was used to assess the degree of neurological impairment of the patients, and the modified Rankin Scale (mRS) was used to assess the patients' ability to live independently. The occurrence of adverse reactions in the two groups was observed and compared.Results:The neutrophil to lymphocyte ratio (NLR) and neutrophil (N) in the study group were lower than those in the control group : 1.71 ± 0.05 vs. 2.04 ± 0.31, 0.261 ± 0.012 vs. 0.403 ± 0.021 at follow-up for 3 months, there were statistical differences ( P<0.05). The levels of low density lipoprotein cholesterol (LDL-C), total cholesterol (TC) and triacylglycerol (TG) in the study group were lower than those in the control group at follow-up for 3 months:(1.59 ± 0.48) mmol/L vs. (2.09 ± 0.69) mmol/L, (2.92 ± 0.44) mmol/L vs. (3.57 ± 0.71) mmol/L, (1.19 ± 0.24) mmol/L vs. (1.37 ± 0.21) mmol/L, the level of high density lipoprotein cholesterol (HDL-C) was higher than that in the control group : (1.24 ± 0.19) mmol/L vs. (1.06 ± 0.21) mmol/L, there were statistical differences ( P<0.05). The levels of AIM2 and LTB4 in the study group were lower than those in the control group at discharge and follow-up for 3 months: (945.20 ± 123.60) ng/L vs. (1 094.40 ± 227.10) ng/L, (948.90 ± 135.80) ng/L vs. (1 236.90 ± 125.70) ng/L, (115.80 ± 20.60) ng/L vs. (129.70 ± 31.50) ng/L, (116.40 ± 21.10) ng/L vs. (130.30 ± 32.60) ng/L, there were statistical differences (P<0.05). The NHISS scores in the study group was lower than that in the control group at follow-up for 3 months: 2.00(1.00, 3.00) scores vs. 4.00(3.00, 5.00) scores, there was statistical difference ( P<0.05). After follow-up for 3 months, the mRS scores and incidence of adverse reactions between the two groups had no statistical differences ( P<0.05). Conclusions:The combination of atorvastatin and ezetimibe in the early stage of AIS thrombectomy can significantly reduce the levels of NLR, serum AIM2 and LTB4, improve blood lipid levels, reduce the degree of neurological impairment, and improve the ability of patients to carry out activities of daily living, with high safety.

OBJECTIVE To evaluate the efficacy,safety and economics of the centrally procured generic versus original esomeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding(ANVUGIB).METHODS A retrospective collection of real-world clinical data was conducted for ANVUGIB patients who received treatment at Shenzhen People's Hospital and University of Hong Kong-Shenzhen Hospital from January 2018 to March 2024.Patients were divided into imported original drug group(original drug group,221 cases)and centrally procured generic drug group(generic drug group,75 cases)according to the types of drug used.Propensity score matching(PSM)was performed at a ratio of 3∶1 to compare the clinical efficacy,safety and economics between the two groups.RESULTS Totally 241 patients were included after PSM,with 170 in the original drug group and 71 in the generic drug group.There were no significant differences between the two groups in terms of rebleeding rate,rate of second endoscopic intervention,blood transfusion rate,length of hospital stay,mortality due to gastrointestinal bleeding,30-day readmission due to rebleeding,and overall survival rate(P＞0.05).The incidence of adverse events among all patients in both groups also showed no statistically significant difference(P＞0.05);furthermore,the adverse events reported by the respective hospitals to the National Center for ADR Monitoring were comparable between the two groups.After PSM,the median total drug cost and high-dose esomeprazole cost in the generic drug group were significantly lower than those in the original drug group,while the median nursing fee and bed fee were significantly higher than those in the original drug group(P＜0.05).There was no statistically significant difference between the two groups in terms of median total hospitalization expenses,total treatment costs,laboratory fees,examination fees,material costs,or consultation fees(P＞0.05).CONCLUSIONS The clinical efficacy and safety of centrally procured generic esomeprazole in the treatment of ANVUGIB are comparable to those of the original drug,and it is more economical.

ObjectiveTo understand the protective effect of pentavalent rotavirus （RV） vaccine in preventing infectious diarrhea among infants and young children， and to provide a basis for formulating prevention and control strategies for this population. MethodsA retrospective cohort study was conducted to follow up resident children born in Pinghu City from January 2019 to June 2021 for two years. Data on morbidity and pentavalent RV vaccine inoculation were collected to analyze the incidence density of rotavirus infection among children inoculated with different doses of the pentavalent RV vaccine， and to calculate the vaccine protection rate. ResultsA total of 5 141 resident children were surveyed， with a RV vaccination rate of 31.63% and a full vaccination rate of 30.83%. There were 154 cases of RV infection， with an incidence density of 1 392.69/100 000 person-years. Among the 875 migrant children （17.02%）， the full vaccination rate was 20.46%， while among the 4 266 local children （82.98%）， the full vaccination rate was 32.96%. The difference in full vaccination rate between migrant children and local children was statistically significant （χ²=53.209， P<0.001）. The proportions of boys and girls were 51.94% and 48.06%， respectively， with a full vaccination rate of 29.74% and 32.01%， respectively； and the difference was not statistically significant （χ²=3.111， P=0.078）. The proportions of children with normal birth weight and abnormal birth weight were 91.56% and 8.44%， respectively， with a full vaccination rate of 31.82% and 20.05%， respectingly； and the difference was statistically significant （χ²=25.852， P<0.001）. Among the 3 515 children who were not vaccinated with the pentavalent RV vaccine， 118 of which were infected， with an incidence density of 1 503.32/100 000 person-years （with an incidence rate of 3.36%）. Among the 41 children who were partially vaccinated （received only 1-2 doses）， the incidence density was 1 058.54/100 000 person-years （with an incidence rate of 2.44%）. Among the 1 585 fully vaccinated children， 35 of which were infected， with an incidence density of 1 123.96/100 000 person-years （with an incidence rate of 2.21%）； and the difference in incidence rate was statistically significant （χ²=4.988， P=0.026）. The protection rate for partial vaccination was 28.00% （95%CI：22.00%‒33.50%）， while for full vaccination was 35.10% （95%CI： 29.80%‒40.00%）. ConclusionPentavalent RV vaccination can effectively prevent rotavirus infection in infants and young children， in which the full vaccination is more effective than partial vaccination. It is recommended to strengthen the monitoring of circulating RV strains in the city， develop more targeted vaccines， and increase the RV vaccine coverage rate and full vaccination rate among infants and young children through the expansion of the national immunization program and enhancement of public education， so as to effectively reduce the incidence of infectious diarrhea in infants and young children.
