The left ventricular (LV) myocardial remodeling process that occurs in various settings of congestive heart failure (CHF) had historically been attributed to intrinsic changes in the cardiac myocyte. However, it is now recognized that important changes also occur within the extracellular matrix (ECM) of the myocardium, contributing to the remodeling process. Matrix metalloproteinases are a family of proteolytic enzymes responsible for myocardial extracellular protein degradation.Several MMP species identified within the human myocardium may be dysregulated in congestive heart failure (CHF). The purpose of the present review is to present a brief overview of the matrix metalloproteinases (MMPs) within the myocardium that likely contributes to myocardial remodeling,to examine the results from basic studies to explore relationship with respect to MMPs activation and congestive heart failure.-

Objective To investigate the therapeutic effects of recombinant adeno-associated virual gene serotype 1(rAAV1) mediated transfer of sarcoplasmic reticulum Ca2+ ATPase(SERCA2a) on beagle dogs with heart failure(HF).Methods The chronic HF model was reproduced in beagle dogs by giving rapid right ventricular pacing(230 beats/min) for 30 days.A reduced rate(180 beats/min)was continued for another 30 days.Sixteen beagle dogs were divided into four groups(4 each): control group,HF group,HF+EGFP group and HF+SERCA2a group.After rapid pacing for 30 days,rAAV1-EGFP(1?1012vg/ml) and rAAV1-SERCA2a(1?1012vg/ml) were respectively delivered via intramyocardial routes,while no treatment was given to the animals in both control and HF groups.At the end of the study,haemodynamics,echocardiography and the protein expression of SRCA2a were measured respectively.The apoptosis index of cardiac myocyte was evaluated by TUNEL.Bax expression was assessed by immunohistochemistry.Results After gene transfer of SERCA2a in HF beagle dogs for 30 days,the heart function was improved along with an increase in SERCA2a expression.Left ventricular systolic function was significantly increased,including the left ventricular systolic pressure(LVSP),left ventricular maximal rate of pressure rise(LV+dp/dtmax),left ventricular maximal rate of pressure decline(LV-dp/dtmax,P

Objective To observe the effect of sitagliptin on carotid intima-media thickness (c-IMT) and serum hs-CRP and IL-6 levels in the patients with newly diagnosed type 2 diabetes mellitus. Methods 65 patients with newly diagnosed type 2 diabetes mellitus who were admitted to the outpatient clinic and were hospitalized in our hospital were selected. They were randomly divided into sitagliptin phosphate tablet group (experimental group) with 35 cases and metformin hydrochloride tablet group (control group) with 30 cases. All patients were given health education about diabetes, diet guidance and exercise. All patients were given drawing of venous blood at a fasting condition ≥10 h before treatment and 6 months after treatment to determine the following indicators: FPG, 2 hPG, hs-CRP, IL-6, TC, TG, HDL-c, LDL-c, HbA1 c, hs-CRP, IL-6, etc, and c-IMT was determined. Results There was no statistically significant difference in blood glucose, blood lipids, inflammation index and c-IMT between the two groups before treatment (P>0.05); after treatment, FPG, 2 hPG and HbA1 c were significantly lower than those before treatment in both groups, and the difference was statistically significant (P<0.01). There were statistically significant differences in FPG and HbA1 c between the two groups (P<0.01). There was no statistically significant difference in 2-hour postprandial blood glucose between groups (P>0.05). The c-IMT, hs-CRP and IL-6 levels in the experimental group after treatment were significantly lower than those before treatment, and the differences were statistically significant (P<0.05). There was no significant change in c-IMT in control group after treatment (P>0.05). hs-CRP and IL-6 had a decreasing trend compared with those before treatment, and the difference was not statistically significant (P>0.05). There were statistically significant differences in c-IMT, hs-CRP and IL-6 between the two groups after treatment (P<0.05). Spearman linear correlation analysis: c-IMT was positively correlated with hs-CRP levels and IL-6 (r=0.6585, P=0.000; r=0.571, P=0.000). There was no significant correlation between fasting blood glucose and glycosylated hemoglobin (P>0.05). Conclusion The DPP-4 inhibitor of sitagliptin has a clear hypoglycemic effect and can reduce c-IMT, hs-CRP and IL-6. The anti-inflammatory effects besides hypoglycemic effect may be involved in the reduction of atherosclerosis in the patients with diabetes mellitus.

Background:At present,domestic guidelines and consensus recommend the use of nutritional risk screening 2002(NRS 2002)and patient-generated subjective global assessment(PG-SGA)for nutritional risk screening and assessment of patients with gastrointestinal cancer during the perioperative period.However,PG-SGA has higher professional requirements,complex content and time-consuming.In the current busy situation of medical staff,NRS 2002 is more used for screening alone.Aims:To explore the consistency of NRS 2002 and PG-SGA in the assessment of nutritional status and clinical outcomes in patients with gastrointestinal malignancies,and to explore the accuracy of screening using NRS 2002 alone,so as to provide guidance for the establishment of clinical nutritional screening and assessment standards.Methods:A retrospective analysis was conducted on 157 patients with gastrointestinal malignancies who underwent radical operation in the Department of Gastrointestinal Surgery of Xiangya Hospital,Central South University from January 2020 to October 2022.Nutritional screening and evaluation were performed by NRS 2002 and PG-SGA scales and demographic data and nutrition-related laboratory indicators were collected to observe short-term postoperative clinical outcomes.Results:Patients with nutritional risk or malnutrition had lower body mass index(BMI),lymphocytes and prealbumin(P<0.05).The correlation and consistency of NRS 2002 and PG-SGA scales were good(r=0.728,κ=0.46)and the areas under the curve(AUC)for predicting postoperative complications were 0.691 and 0.702,respectively.In addition,nutritional risk and postoperative complications were significantly increased in patients with malnutrition(P<0.05).Conclusions:Therefore,gastrointestinal surgeons can only use NRS2002 to perform nutritional screening of patients and make corresponding nutritional treatment according to the screening results in the case of busy clinical work.

Both immunosuppressants and antibiotics (ABX) are indispensable for transplant patients. However, the former increases the risk of new-onset diabetes, whereas the latter impacts intestinal microbiota (IM). It is still unclear whether and how the interaction between immunosuppressants and ABX alters the IM and thus leads to glucose metabolism disorders. This study examined the alterations of glucose and lipid metabolism and IM in mice exposed to tacrolimus (TAC) with or without ABX. We found that ABX further aggravated TAC-induced glucose tolerance and increased insulin secretion. Combined treatment resulted in exacerbated lipid accumulation in the liver. TAC-altered microbial community was further amplified by ABX administration, as characterized by reductions in phylum Firmicutes, family Lachnospiraceae, and genus Coprococcus. Analyses based on the metagenomic profiles revealed that ABX augmented the effect of TAC on microbial metabolic function mostly related to lipid metabolism. The altered components of gut microbiome and predicted microbial functional profiles showed significant correlation with hepatic lipid accumulation and glucose disorders. In conclusion, ABX aggravated the effect of TAC on the microbiome and its metabolic capacities, which might contribute to hepatic lipid accumulation and glucose disorders. These findings suggest that the ABX-altered microbiome can amplify the diabetogenic effect of TAC and could be a novel therapeutic target for patients.
