Objective: To explore levels of anti-oxidative molecules and inflammatory factors in patients with vascular dementia (VD) and their clinical significance. Methods: Sixty VD patients admitted in our hospital from January 2016 to January 2019 were classified into an experimental group, while another 60 healthy patients seeking physical examinations in the corresponding period were selected as a control group. Various indexes related to serum inflammatory factors and anti-oxidative molecules were compared among patients in such two groups. For the purpose of comparing anti-oxidative molecular expression levels and inflammatory factor levels in patients with VD of different severities, 60 cases in the experimental group were divided, based on a Mini-mental State Examination (MMSE) scale, into patients with mild symptoms (n=20, score: 21~26), patients with moderate symptoms (n=22, score: 10~20) and patients with severe symptoms (n=18, score: 0~9). Results: By contrast to the control group, levels of inflammatory factors (e.g., TNF-a, CRP and IL-б) in VD patients are all significantly increased and their differences show statistical significance (p<0.05); and, expression levels of anti-oxidative factors, including superoxide dismutase (SOD), glutathion peroxidase (GSH-Px), total antioxidant capacity (TAC), catalase (CAT) and glutathione reductase (GR), in the experimental group are apparently below those of the control group (P<0.05). As dementia degree increases, expression levels of serum anti-oxidative molecules in such patients are inclined to drop in a significant way (P<0.05), while inflammatory factor levels tend to go up gradually (P<0.05). Conclusions: If compared with the normal population, inflammatory factor levels in serum of VD patients are higher; however, expression levels of anti-oxidative molecules become below those of the normal population. Additionally, levels of inflammatory factors and anti-oxidative molecules may change obviously as severity of illness increases. This suggests that inflammation and oxidation play a certain role of auxoaction in VD patients. doi: https://doi.org/10.12669/pjms.37.5.3854 How to cite this:Qi FX, Hu Y, Li YW, Gao J.

Objective: This study aims to evaluate the clinical effect of alteplase combined with butylphthalide in treating patients with acute anterior circulation cerebral infarction. Methods: Retrospective study methods were used. Eighty patient cases with acute anterior circulation cerebral infarction treated in Baoding First Central Hospital, China from January 2018 to December 2020 were randomly and averagely divided into two groups. Patients in the two groups were given symptomatic treatment. Patients in the experimental group were treated with alteplase combined with butylphthalide for thrombolytic therapy, whereas patients in the control group were treated with urokinase thrombolytic therapy. The NIHSS score, effective rates and neurological function recovery were analysed one day, seven days and 30 days after treatment were analyzed, respectively. So as the incidence of adverse reactions within seven days after drug adminutesistration. Results: The NIHSS scores of the two groups were significantly lower than those before treatment on one day, seven days and 30 days after treatment (experimental group, p=0.00; control group, p=0.02). The experimental group was more significantly lower than the control group (p=0.00). The effective rate of the experimental group was significantly higher than that of the control group (p=0.03), and the recovery rate after treatment was significantly higher than that of the control group (p=0.04). Within one week after treatment, the complication rate was 15% in the experimental group and 20% in the control group but was not significantly different (p=0.56). Conclusion: Alteplase combined with butylphthalide is effective and safe in the treatment of acute anterior circulation cerebral infarction without obvious complications. doi: https://doi.org/10.12669/pjms.37.4.3986 How to cite this:Qi FX, Hu Y, Wang S.

Objectives: To investigate the effects of etibatide combined with emergency percutaneous coronary intervention (PCI) on blood perfusion and cardiac function in acute myocardial infarction (AMI) patients. Methods: This was a prospective, randomized, controlled study. From November 2015 to June 2019, 196 patients with ST-segment elevation myocardial infarction (STEMI) undergoing emergency PCI admitted to Baoding First Central Hospital were enrolled. The 196 STEMI patients were randomly divided into experimental group and control group. In the experimental group, STEMI patients were treated with emergency PCI + etibatide; while in the control group, only PCI was performed. Observation indexes included: general data, myocardial perfusion and cardiac function indexes and major adverse cardiac events (MACE). Results: There was no significant difference in general data between the two groups (P > 0.05). The rate of ST-segment resolution (STR) in the experimental group was better than that in the control group (P < 0.05). In myocardial contrast echocardiography (MCE), higher peak intensity (PI) and shorter time-to-peak (TP) were observed in the experimental group compared with the control group (P < 0.05). The platelet aggregation rate was compared between the two group at the time points of before PCI, after PCI and two hour after drug withdrawal, and there was no significant change in the platelet aggregation rate of the control group between different time points (before PCI, after PCI and two hour after drug withdrawal); while the platelet aggregation rate of the experimental group was significantly lower after PCI and two hour after drug withdrawal than that before PCI (P < 0.05), and an obviously decreased platelet aggregation rate was found in the experimental group(P < 0.05). After three months of follow-up, there was one case of MACE in the experimental group and 1 case of MACE in the control group, without any difference in the incidence of MACE between the two groups (P > 0.05). Conclusion: Etibatide combined with emergency PCI could improve myocardial reperfusion and cardiac function in patients with acute STEMI without increasing the incidence of MACE. doi: https://doi.org/10.12669/pjms.37.1.2950 How to cite this:Hu Y, Qi F, Yu L, Geng W.
