Objective To investigate the effect of tirofiban combined with oxiracetam on acute anterior circulation progressive cerebral infarction.Methods A total of 171 patients with acute anteri-or circulation progressive cerebral infarction from October 2022 to January 2024 were enrolled and ran-domly divided into three groups using a random number table.The control group of 57 patients re-ceived conventional treatment,the observation group A received tirofiban in addition to conventional treatment,and the observation group B received oxiracetam on the basis of observation group A's treat-ment.The effectiveness indicators[including the rates of neurological improvement and neurological deterioration at 14 days after treatment,the rate of good prognosis and modified Rankin Scale(MRS)scores at 90 days after treatment,as well as the National Institutes of Health Stroke Scale(NIHSS)scores at 7 and 14 days after treatment and their differences from baseline],cognitive function[as-sessed using the Montreal Cognitive Assessment(MOCA)],and safety indicators(incidence rates of symptomatic intracranial hemorrhage,fatal intracranial hemorrhage,and mortality at 90 days after treat-ment)were compared among the three groups.Results There were no statistically significant differ-ences in the rates of neurological improvement and neurological deterioration at 14 days after treatment,the rate of good prognosis,and MRS scores at 90 days after treatment among the three groups(P＞0.05).There were statistically significant differences in NIHSS scores between baseline and 7 and 14 days after treatment in all three groups(P＜0.05),and the differences in NIHSS scores from baseline at the above time points were higher in observation group B than in observation group A and the control group(P＜0.05).There were no statistically significant differences in MOCA scores among the three groups before treatment(P＞0.05);however,the MOCA scores in the observation group B were higher than those in observation group A and the control group at 14,30,and 90 days after treatment(P＜0.05).There were no statistically significant differences in the incidence rates of symptomatic intracranial hemorrhage,fatal intracranial hemorrhage,and mortality at 90 days after treatment among the three groups(P＞0.05).Conclusion Tirofiban combined with oxiracetam can improve cognitive function in patients with acute anterior circulation progressive cerebral infarc-tion without increasing the risk of hemorrhage,and has better prognosis.

Objective To explore the efficacy of auricular plaster therapy with press needles combined with eszopiclone tablets in the treatment of patients with post-stroke insomnia(PSI)and its effect on the serum levels of brain-derived neurotrophic factor(BDNF)and interleukin-1β(IL-1β).Methods A total of 120 PSI patients were selected as the study subjects and randomly divided into group A(60 cases)and group B(60 cases).Group A was treated with eszopiclone tablets,while group B was treated with auricular plaster therapy with press needles combined with eszopiclone tab-lets.Both groups received continuous treatment for 4 weeks.The clinical efficacy,sleep status,in-flammatory factors,neurotrophic factors,psychological state,quality of life,and adverse reactions were compared between the two groups after treatment.Results After treatment,the total clinical effective rate in the group B was 93.33％,which was higher than 80.00％in the group A(P＜0.05).The levels of tumor necrosis factor-α(TNF-α),IL-1β,IL-6,norepinephrine(NE),the scores of Pittsburgh Sleep Quality Index(PSQI),Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),and Self-rating Scale of Sleep(SRSS)in both groups were lower than those before treatment(P＜0.05),and the above indicators in the group B were lower than those in group A,with statistically significant differences(P＜0.05).The levels of 5-hydroxytryptamine(5-HT),BDNF,and the scores of Stroke-Specific Quality of Life Scale(SS-QOL)were higher than those be-fore treatment,and the levels in the group B were higher than those in the group A,with statistically significant differences(P＜0.05).There was no statistically significant difference in the total inci-dence of adverse reactions between the two groups(P＞0.05).Conclusion Auricular plaster therapy with press needles combined with eszopiclone tablets can improve the clinical efficacy,sleep status,and quality of life in PSI patients,reduce the levels of BDNF and IL-1β,alleviate anxiety and depression,and have high safety.

Objective To evaluate the efficacy,safety,and economy of 4 intravenous iron formulations in the treatment of iron deficiency anemia(IDA)by rapid health technology assessment,and to provide evidence for clinical decision-making.Methods PubMed,Embase,the Cochrane Library,CNKI,WanFang,SinoMed,and official websites of international health technology assessment agencies were electronically searched to collect health technology assessment reports,systematic reviews/Meta-analysis,and pharmacoeconomic studies concerning the treatment of IDA with iron sucrose(IS),iron dextran(ID),ferric carboxymaltose(FCM),and iron isomaltoside(IIM)from the inception to August 15,2024.Two researchers independently screened the studies,extracted data and assessed the quality of included studies.The results were then qualitatively described and analyzed.Results A total of 32 studies were included,including one health technology assessment report,16 systematic reviews/Meta-analysis,and 15 pharmacoeconomic evaluations.In terms of effectiveness,FCM had a higher response rate than that of IS(P＜0.05),FCM and IIM had no statistical difference(P＞0.05).Regarding hemoglobin level change,patients treated with FCM had higher hemoglobin levels than those treated with IS(P＜0.05);the improvement in hemoglobin levels between IIM and FCM was inconclusive.In terms of ferritin level change,FCM might be superior to the other three intravenous iron formulations.In terms of safety,the adverse event rates for FCM,IS,ID and IIM were 12.0％,15.3％,12.0％and 17.0％,respectively;IIM was significantly associated with a lower rate of cardiovascular adverse events compared to FCM and IS(P＜0.05);FCM had the highest rate of hypophosphatemia among the four formulations(P＜0.05),and there was no significant difference among IIM,IS and ID(P＞0.05);IIM had a lower risk of severe or serious hypersensitivity reactions compared to FCM and IS.In terms of economy,FCM and IIM had an economic advantage compared to IS.The economic efficiency ranking among IS,ID,and FCM was in the order of FCM,ID,and IS,the economic comparison between FCM and IIM remains inconclusive and needs to be further demonstrated.Conclusion FCM and IIM have good efficacy,safety and economy in the treatment of IDA,but most of the included economy studies based on foreign populations,and domestic economic studies need to be further demonstrated.

OBJECTIVE:To explore the content variation rule and influencing factors of 5-hydroxymethylfurfural(5-HMF)in the extraction process of the herbs Schisandra chinensis and improve the quality of monitoring the extract of Schisandra chinensis. METHODS:High performance liquid chromatography was adopted to determine the contents of 5-HMF in the extracts during the extraction process (decoction,vacuum concentration,alcohol precipitation,vacuum drying,alkali adjustment),and the content variation rule was found out. For vacuum drying during which the content of 5-HMF reduced obviously,the effects of the tempera-ture and time of drying on the content of 5-HMF were studied,and the effects of vacuum drying and freeze drying on the 5-HMF contents were compared. RESULTS:The content variation trend in the extraction process of Schisandra chinensis was as follows as a large amount of 5-HMF was produced in the herbs decoction process;the content of 5-HMF increased during concentration,re-duced during the alcohol precipitation and the vacuum drying of the extracts by three times concentrate,and maintained substantial-ly unchanged during alkali adjustment. In the process of vacuum drying,the content of 5-HMF decreased with temperature rise and time extension. Freeze drying had no effect as good as that of vacuum drying in the reduction in the content of 5-HMF. CON-CLUSIONS:It is suggested that the vacuum drying of the extracts by three times concentrate at higher temperature,which may pro-duce the extract of Schisandra chinensis with lower content of 5-HMF and thus improve the quality of Schisandra chinensis extract.

Objective To evaluate the value of peak time(PT) and corrected peak time(PTc) in the assessment of left ventricular long axis systolic function in patients with dilated cardiomyopathy(DCM).Methods Thirty-one DCM cases and thirty-six healthy cases were investigated using echocardiography.To obtain image of apical four-chamber view and apical two-chamber view, PT was measured by the technique of tissue motion annular displacement.The value of PTc was corrected by R-R interval.The critical value of PT and PTc was obtained by ROC curves.Results Compared with the PT of control group, the PT of DCM group at the site of septal and lateral were significantly increased ( P ＜0.05), but the PT at the site of anterior and inferior were no significantly increased ( P ＞0.05).The PTc at the four sites were significantly increased compared with control group ( P ＜0.05).The areas of under the ROC curve of PTc was 0.849 (95 % CI 0.699～0.929, P = 0.000), sensitivity and specificity of diagnosis cardiac dysfunction were 80.6 % and 66.7% respectively.Conclusions The PTc was significantly increased in patients with DCM.PTc was useful to evaluate left ventricular dysfunction in DCM patients.
