Fractures have an extraordinarily negative impact on individuals'quality of life and functional status.Nonunion or disability of fracture is a major health issue with important clinical,social,and economic implications.1 Mesenchymal stem cells(MSCs)play an indispensable role in the initiation of the fracture repair process including the formation of a callus which is replaced by new bone.The use of MSCs in the treatment of fractures is very attractive as they can reduce the time of healing and occurrence of nonunion.

BACKGROUND Patients with chronic heart failure(CHF)frequently develop hyperuricemia,an elevated serum uric acid level,associated with adverse outcomes.Dapagliflozin,a sodium-glucose cotransporter-2 inhibitor,demonstrates reduction in cardiovascular mortality and hospitalization in patients with CHF and ejection fraction(HFrEF),irrespective of diabetes.However,dapagliflozin’s effect on the uric acid levels in patients with CHF and hyperuricemia remain unclear.AIM To investigate the effects of dapagliflozin on uric acid levels in CHF patients with hyperuricemia.METHODS We conducted a randomized,double-blind,placebo-controlled trial in 200 patients with CHF and hyperuricemia,with HFrEF and serum uric acid levels≥7 mg/dL(≥416μmol/L).The participants were randomly assigned to receive a daily dose of 10 mg dapagliflozin or placebo for 24 months.The primary endpoint was the change in serum uric acid level from baseline to 24 months.Secondary endpoints included changes in left ventricular ejection fraction(LVEF),Nterminal pro-B-type natriuretic peptide(NT-proBNP),and quality of life(QoL)scores,as well as the incidence of cardiovascular death and hospitalization for heart failure.RESULTS At 24 months,dapagliflozin significantly reduced serum uric acid levels by 1.2 mg/dL(71μmol/L)compared with placebo(95%CI:-1.5 to-0.9;P<0.001).Dapagliflozin also significantly improved LVEF by 3.5%(95%CI:2.1-4.9;P<0.001),NT-proBNP by 25%(95%CI:18-32;P<0.001),and QoL scores by 10 points(95%CI:7-13;P<0.001)and reduced the risk of cardiovascular death and hospitalization for heart failure by 35%(95%CI:15–50;P=0.002)compared with the placebo.Adverse events were similar between the two groups,except for a higher rate of genital infections in the dapagliflozin group(10%vs 2%,P=0.01).CONCLUSION Dapagliflozin significantly lowered serum uric acid levels and improved the clinical outcomes in patients with CHF and hyperuricemia.Therefore,dapagliflozin may be a useful therapeutic option for this high-risk population.

The prevalence of hyperlipidemia has increased significantly due to genetic, dietary, nutritional and pharmacological factors, and has become one of the most common pathological conditions in humans. Hyperlipidemia can lead to a range of diseases such as atherosclerosis, stroke, coronary heart disease, myocardial infarction, diabetes, and kidney failure, etc. High circulating low-density lipoprotein cholesterol(LDL-C) is one of the causes of hyperlipidemia. LDL-C in the blood binds to LDL receptor(LDLR) and regulates cholesterol homeostasis through endocytosis. In contrast, proprotein convertase subtilisin/kexin type 9(PCSK9) mediates LDLR degradation via the intracellular and extracellular pathways, leading to hyperlipidemia. Targeting PCSK9-synthesizing transcription factors and downstream molecules are important for development of new lipid-lowering drugs. Clinical trials regarding PCSK9 inhibitors have demonstrated a reduction in atherosclerotic cardiovascular disease events. The purpose of this review was to explore the target and mechanism of intracellular and extracellular pathways in degradation of LDLR and related drugs by PCSK9 in order to open up a new pathway for the development of new lipid-lowering drugs.

Aortic valve calcification disease (CAVD) is the most prevalent degenerative valve disease in humans, leading to significant morbidity and mortality. Despite its common occurrence, our understanding of the underlying mechanisms remains incomplete, and available treatment options are limited and risky. A more comprehensive understanding of the biology of CAVD is essential to identify new therapeutic strategies. Animal models have played a crucial role in advancing our knowledge of CAVD and exploring potential treatments. However, these models have inherent limitations as they cannot fully replicate the complex physiological mechanisms of human CAVD. In this review, we examine various CAVD models ranging from pigs to mice, highlighting the unique characteristics of each model to enhance our understanding of CAVD. While these models offer valuable insights, they also have limitations and shortcomings. We propose that the guide wire model shows promise for future CAVD research, and streamlining the methodology could enhance our understanding and expand the research scope in this field.

The tumor heterogeneity results in different clinical characteristics of tumor patients,so precise therapy is a popular treatment strategy clinically.Microsatellite instability(MSI)is found in 10%-15%of colorectal cancer(CRC)patients and exhibits different clinical outcomes than microsatellite stable(MSS)patients.Surprisingly,MSI patients have a better prognosis than patients with stable microsatellites.Msl patients exhibit clinical features that are not responsive to chemotherapy,however,Msl patients showed excellent responses to immunotherapy.'Although the subtype classification of MSI is beneficial to the clinical treatment of CRC patients,the mechanism of MSl remains unclear.
