Insulin pumps go by the name of the second revolution of treatment for diabetes. The result of DCCT publicized in 1993, insulin pumps have been popularized in the world, including China. This article introduces such about insulin pumps as its history, actuality, development trend, advantages and disadvantages.

Objective To explore the clinical effect of urapidil combined with recombinant human brain natriuretic peptide(rhBNP)in the treatment of high blood pressure complicated with acute heart failure.Methods Sixty patients with high blood pressure(HBP)and acute heart failure(AHF)were collected from May 2022 to December 2023 in the inpatient department of Yingtan People's Hospital were to conduct retrospective analysis.They were divided into two groups according to different clinical drugs,with 30 cases in each group.The control group received conventional drugs(amlodipine besylate+spirolactone)+intravenous furosemide infusion+administer urapidil intravenously,the experimental group was additionally given rhBNP.Both groups received treatment for 7 days in the hospital.Blood pressure,heart rate,N-terminal pro-brain natriuretic peptide(NT-proBNP),left heart function changes and adverse reactions during treatment were compared in two groups.Results After the treatment of those patients,the total effective rate and left ventricular ejection fraction of experimental group were higher than those of control group(P＜0.05).The changes of heart rate,NT-proBNP,left ventricular end-systolic diameter,left ventricular end-diastolic diameter and blood pressure in experimental group were lower than those in control group(P＜0.05).Two groups were no significant difference in the total incidence of adverse drug reactions(P＞0.05).Conclusion Urapidil and rhBNP is obviously superior to urapidil alone in the treatment of HBP complicated with AHF,and can obviously reduce blood pressure and heart rate,improve cardiacfunction,and is safe in clinical application.

Objective:To classify the etiology of secondary hemophagocytic syndrome (sHLH) and explore its clinical, laboratory and therapeutic characteristics in order to deepen the understanding of the disease.Method:A retrospective observational study was conducted on sHLH patients who were treated at Peking University People's Hospital from January 2016 to December 2021. Patients under the age of 18 and those with missing clinical data were excluded. The distribution of departments visited and etiologies of sHLH were analyzed. Baseline data, clinical characteristics, complications, laboratory data, treatment, and in-hospital outcomes of sHLH were collected. The sHLH patients were then divided into 3 groups including malignancy group, macrophage activation syndrome (MAS) group and other etiologies (mainly infection) group. Intergroup comparisons were performed using chi-square tests, analysis of variance, Mann-Whitney tests, and other statistical methods.Results:A total 169 patients were enrolled, among these patients, 27.8% were malignancy-related HLH, 47.9% were MAS, and 24.3% were other etiologies related HLH. Statistical analysis revealed that the clinical characteristics of other etiological group was highly consistent with the malignancy group, including more and severer peripheral blood cell reduction, higher sCD25 levels, more Epstein-Barr virus infection, and the prognosis was similar, both were with more than 50% in-hospital mortality. And the incidence of hemophagocytosis was highest in other etiological groups (65.9%). In contrast, MAS group was with an obviously lower mortality of 17.3% ( P<0.05). Meanwhile, treatments including methylprednisolone pulse, cyclosporine A and interleukin-2 were used frequently in MAS group. Conclusion:Malignancy related HLH and other etiologies related HLH exhibit more similar clinical characteristics and prognosis, while the MAS group, has a milder overall condition and better prognosis.
