Objectives:To determine the validity of uric acid as a potential prognostic marker for long-term outcomes of patients with acute myocardial infarction (AMI) and those with AMI undergoing percutaneous coronary intervention (PCI).Methods:Systematic review and meta-analysis were performed. We retrieved data from retrospective and prospective cohort studies that investigated whether serum uric acid (SUA) level affects the prognosis of patients with AMI.Results:Thirteen studies involving 9371 patients were included. High serum uric acid (HSUA) level increased mid/long-term mortality (risk ratio (RR)=2.32, 95% confidence intervals (CI): 2.00–2.70) and had higher short-term mortality (RR=3.09, 95% CI: 2.58–3.71), higher mid/long-term major adverse cardiovascular events (MACE) risk (RR=1.70, 95% CI: 1.54–1.88), and higher short-term MACE risk (RR=2.47, 95% CI: 2.08–2.92) for patients with AMI. In the PCI subgroup, the HSUA level also increased mid/long-term mortality (RR=2.33, 95% CI: 1.89 to 2.87) and had higher mid/long-term MACE risk (RR=1.64, 95% CI: 1.48–1.82), and higher short-term MACE risk (RR 2.43, 95% CI: 2.02–2.93) for patients who were treated with PCI after AMI. Particularly in the PCI subgroup, a higher short-term mortality (RR=6.70, 95% CI: 3.14–14.31) was presented in the group with lower HSUA cut-off level, and the mortality was higher than the group with higher HSUA cut-off level (RR=2.69, 95% CI: 2.09–3.46).Conclusion:The HSUA level significantly increased the mortality and MACE risk of patients with AMI. Mild elevation of SUA levels (normal range) have started to have a significant impact on the short-term mortality of patients who underwent PCI, and has not received the attention of previous studies. However, this condition should be further investigated.

Background: The treatment of hypertensive nephropathy has remained unchanged for many years. Salvianolate is the main active component extracted from Salvia Miltiorrhiza. The current studies seem to suggest that salvianolate has a certain therapeutic effect on hypertensive nephropathy.Objective: The purpose of this meta-analysis is to evaluate the effect and safety of salvianolate on hypertensive nephropathy under the condition of standardized use of valsartan.Methods: We conducted a systematic search (unlimited initial date to 22 October 2022) in PubMed, Web of Science, the Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang Data knowledge service platform, China Science and Technology Journal Database, China Biomedical Literature Service System. Searching for the study of salvianolate on hypertensive nephropathy. Two reviewers independently included the study that met the inclusion criteria, and extracted data, evaluated the quality of the study. We use RevMan5.4 and stata15 software for this meta-analysis. We use GRADEprofiler 3.2.2 software for evidence quality assessment.Results: This meta-analysis included seven studies (525 patients). Compared with the use of valsartan combined with conventional treatment, salvianolate combined with valsartan and conventional treatment can further improve the efficacy (RR = 1.28, 95%CI:1.17 to 1.39), reduce blood pressure [systolic blood pressure (MD = 8.98, 95%CI:−12.38 to −5.59); diastolic blood pressure (MD = 5.74, 95%CI:−7.20 to −4.29)], serum creatinine (MD = −17.32, 95%CI:−20.55 to −14.10), blood urea nitrogen (MD = −1.89, 95%CI:−3.76 to −0.01), urine microalbumin (MD = −23.90, 95%CI:−26.54 to −21.26), and urinary protein to creatinine ratio (MD = −1.92, 95%CI:−2.15 to −1.69), cystatin C (MD = −1.04, 95%CI: −1.63 to −0.45) and increase calcitonin gene-related peptide (MD = 18.68, 95%CI:12.89 to 24.46) without increasing adverse reactions (RR = 2.20, 95%CI:0.52 to 9.40). But it has no additional effect on endothelin-1 and malondialdehyde. The quality of evidence ranged from moderate to very low.Conclusion: This meta-analysis shows that the salvianolate can further improve renal function of hypertensive nephropathy patients based on valsartan was used. Therefore, salvianolate can be used as a clinical supplement for hypertensive nephropathy. However, the quality of the evidence is not high due to the uneven quality of the included studies and the insufficient sample size, we still need a lot of large sample size studies with more perfect design to confirm these results.Systematic Review Registration: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022373256, identifier CRD42022373256

In this work, a novel sausage incorporated with the Pleurotus ostreatus (PO) puree was successfully developed to reduce the residual nitrite and lipid oxidation during refrigerated storage (4 ± 1 °C) for 20 days. Five recipes with the supplement proportion of 0 wt.%, 10 wt.%, 20 wt.%, 30 wt.%, and 40 wt.% PO were produced and their physicochemical properties, nitrite residue, and sensory characteristics were measured. The results show that the content of moisture and all the essential amino acids (especially lysine and leucine) and the non-essential amino acids (especially aspartic and glutamic), lightness, springiness, and water holding capacity of the sausages were increased. However, the content of protein, fat, ash, pH, redness, hardness, gumminess, and chewiness of the sausages was decreased. For the sensory evaluation, the sausage with 20 wt.% PO had better sensory performance including flavor, aroma, and acceptability compared with other experimental groups and the control group. Moreover, the sausages with PO reduced the residual nitrite and inhibited lipid oxidation during storage. All of these results indicate that adding PO puree into pork sausage is a realizable and effective way to obtain nutritional and healthy pork sausages.
