Effect of ulinastatin injection on left ventricular diastolic function in patients with sepsis / 中华急诊医学杂志

Objective:To investigate the effect of ulinastatin injection on left ventricular diastolic function and prognosis in patients with sepsis.Methods:A total of 100 patients with sepsis admitted to the Intensive Care Unit from January 2021 to March 2022 were selected. According to the random number table, they were randomly (random number) divided into the control group (conventional treatment) and experimental group (conventional treatment + ulinastatin injection). The baseline data on admission were compared between the two groups. The echocardiographic indexes [mitral peak velocity of early filling/early diastolic mitral annular velocity (E/e'), early diastolic mitral annular velocity (e'), mitral peak velocity of early filling/ mitral peak velocity of late filling (E/A), and tricuspid regurgitation rate (TRV)], myocardial damage-related and cardiac function-related indicators [troponin I (cTnI), N terminal pro B type natriuretic peptide (NTproBNP)] and inflammation-related indicators [C-reaction protein (CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR)], length of ICU stay, duration of infection control, duration of vasoactive drug use and 28-day mortality were observed and compared between the two groups on admission and 7 days after treatment.Results:On the 7th day after treatment, the levels of e 'and E/A in the experimental group were significantly higher than those in the control group, and the levels of E/e', TRV, cTnI, NTproBNP, CRP and PCT were significantly decreased ( P<0.05). There were no significant differences in duration of infection control and duration of vasoactive drug use between the experimental group and the control group ( P<0.05), but the length of ICU stay was shorter and 28-day mortality was significantly lower in the experimental group than in the control group ( P<0.05). Conclusions:Ulinastatin can reduce the degree of inflammatory response, relieve myocardial injury, improve left ventricular diastolic function, and reduce the length of ICU stay and 28-day mortality in patients with sepsis.

Efficacy and mechanism of new resource medicinal materia Moringa oleifera leaves against hyperlipidemia / 中国中药杂志

High fat diet induced hyperlipidemia hamster model was used to explore the anti-hyperlipidemia effect of water extract of Moringa oleifera leaves( WEMOL). On this basis,the possible action mechanism was predicted by network pharmacology. Golden hamsters were randomly divided into normal diet group( NFD),high-fat diet group( HFD),simvastatin group,high dose group of WEMOL( HIWEMOL) and low dose group of WEMOL( LOWEMOL). The model was administered simultaneously for 66 days,during which the body weight changes of hamsters were recorded. At the end of the experiment,serum lipid level and serum transaminase level of golden hamsters in each group were detected,and the pathological changes of liver were observed by hematoxylin-eosin( HE) staining. The results showed that WEMOL could significantly decrease the serum total cholesterol( TC),total triglyceride( TG),low density lipoprotein cholesterol( LDL-c) levels,and reduce the lipid deposition in liver tissue,thus improving the hyperlipidemia of golden hamsters. According to the prediction of network pharmacology,219 targets of potential active components of M.oleifera leaves and 185 targets of water-soluble potential active components of M. oleifera leaves for the treatment of hyperlipidemia were obtained separately. The MCODE analysis was performed on the PPI network of 219 targets and 185 targets obtained above and got five and four clusters respectively. The signaling pathway analysis of clusters showed that among the common pathways,nonalcoholic fatty liver,insulin resistance,MAPK signaling pathway,estrogen signaling pathway,cell apoptosis and HIF-1 signaling pathway were associated with hyperlipidemia. In addition,the potential active components of M. oleifera leaves could also inhibit the metabolic inflammation of hyperlipidemia by modulating complement and coagulation cascades signaling pathway,and GSK3 B,F2,AKT1,RELA,SERPINE1 might be the key targets. The water-soluble potential active components of M. oliefera leaves could modulate lipid metabolism by modulating AMPK signaling pathway and JAK-STAT signaling pathway,with PIK3 CB,PIK3 CA,CASP3,AKT1 and BCL2 as the key targets. These results suggested that WEMOL had anti hyperlipidemia effect,and its mechanism might be related to the protein expression regulation of lipid metabolism,nonalcoholic fatty liver disease and atherosclerosis related signaling pathways.

The effect of noise exposure on insulin sensitivity in mice may be mediated by the JNK/IRS1 pathway

BACKGROUND@#Epidemiological studies have suggested that noise exposure may increase the risk of type 2 diabetes mellitus (T2DM), and experimental studies have demonstrated that noise exposure can induce insulin resistance in rodents. The aim of the present study was to explore noise-induced processes underlying impaired insulin sensitivity in mice.@*METHODS@#Male ICR mice were randomly divided into four groups: a control group without noise exposure and three noise groups exposed to white noise at a 95-dB sound pressure level for 4 h/day for 1, 10, or 20 days (N1D, N10D, and N20D, respectively). Systemic insulin sensitivity was evaluated at 1 day, 1 week, and 1 month post-noise exposure (1DPN, 1WPN, and 1MPN) via insulin tolerance tests (ITTs). Several insulin-related processes, including the phosphorylation of Akt, IRS1, and JNK in the animals' skeletal muscles, were examined using standard immunoblots. Biomarkers of inflammation (circulating levels of TNF-α and IL-6) and oxidative stress (SOD and CAT activities and MDA levels in skeletal muscles) were measured via chemical analyses.@*RESULTS@#The data obtained in this study showed the following: (1) The impairment of systemic insulin sensitivity was transient in the N1D group but prolonged in the N10D and N20D groups. (2) Noise exposure led to enhanced JNK phosphorylation and IRS1 serine phosphorylation as well as reduced Akt phosphorylation in skeletal muscles in response to exogenous insulin stimulation. (3) Plasma levels of TNF-α and IL-6, CAT activity, and MDA concentrations in skeletal muscles were elevated after 20 days of noise exposure.@*CONCLUSIONS@#Impaired insulin sensitivity in noise-exposed mice might be mediated by an enhancement of the JNK/IRS1 pathway. Inflammation and oxidative stress might contribute to insulin resistance after chronic noise exposure.

The role of central nervous system on hypoglycemia and the feasibility of the brain theory in traditional Chinese medicine on treatment of diabetes mellitus / 中西医结合学报

The central nervous system (CNS) plays a key regulatory role in glucose homeostasis. In particular, the brain is important in initiating and coordinating protective counterregulatory responses when blood glucose levels fall. This may due to the metabolic dependency of the CNS on glucose, and protection of food supply to the brain. In healthy subjects, blood glucose is normally maintained within a relatively narrow range. Hypoglycemia in diabetic patients can increase the risk of complications, such as heart disease and diabetic peripheral neuropathy. The clinical research finds that the use of traditional Chinese medicine (TCM) has a positive effect on the treatment of hypoglycemia. Here the authors reviewed the current understanding of sensing and counterregulatory responses to hypoglycemia, and discuss combining traditional Chinese and Western medicine and the theory of iatrogenic hypoglycemia in diabetes treatment. Furthermore, the authors clarify the feasibility of treating hypoglycemia on the basis of TCM theory and CNS and have an insight on its clinical practice.
