Reoperation due to degenerated bioprostheses is an important factor of high-risk thoracic surgeries. In 2020 ACC/AHA guideline, Valve in Valve (ViV) was recommended for high-risk patient instead of surgical mitral valve replacement. This report described a 77-year-old male patient with a failed mitral bioprosthetic valve, evaluated at high risk of surgery, received a transvenous, transseptal transcatheter mitral valve replacement (TMVR). Tracheal intubation was removed at CCU 3 h after surgery without discomfort such as polypnea. The patient was transferred out of the CCU and discharged on the 3rd day. Compared with transapical access, transvenous transseptal access was less invasive, with shorter duration in CCU and hospitalization.

【Objective】 To investigate the effects of naringenin on the polarization of high-glycemic RAW264.7 macrophages and its related mechanism. 【Methods】 The mother solution of NAR was prepared with dimethyl sulfoxide (DMSO), and the log-growth phase macrophage RAW264.7 was pre-tested. DMEM medium with different glucose concentrations (1, 2, 4, 5 and 6 g/L) was used for cultivation for 24 h. Before the experiment, DMEM was diluted into NAR mixture with different final concentrations, and the effect of NAR on RAW264.7 cell activity was detected by CCK-8 method; nitric oxide synthase (NOS) type classification determination of checkerboard induced nitric oxide synthase (iNOS) active filter was used to control the concentration of sugar and high-sugar stimulation. The control group were subdivided into normal control (NG) and osmotic pressure control (NG+M). The high-glucose stimulation group was divided into normal high glucose (HG), high glucose + naringenin (HG+NAR), high glucose + Fasudil (HG+F), and high glucose +C3 transferase (HG+C3). RAW264.7 was cultured for 24 h in each group; the expression levels of supernatant cytokines, namely, interleukin6 (il-6), tumor necrosis factor -α (TNF-α) and interleukin10 (IL-10), were detected by ELISA. Western blotting was used to determine the RhoA/ROCK pathway related proteins, iNOS and Arg-1 protein levels. Type (M1, M2) and proportion (M1/M2) of macrophages were analyzed by flow cytometry. 【Results】 Compared with those in NG group, in HG group RhoA/ROCK pathway-related proteins and iNOS expression were increased, while Arg-1 expression was decreased (P<0.05). The secretion of pro-inflammatory cytokines IL-6 and TNF-α was increased while anti-inflammatory cytokine IL-10 was decreased (P<0.05). The number of M1-type cells and M1/M2 ratio increased (P<0.05). Compared with HG group, RhoA/ROCK pathway related proteins and iNOS expression were decreased in HG+NAR group, HG+F group and HG+C3 group, while Arg-1 expression was increased, IL-6 and TNF- α secretion was decreased, IL-10 was increased, M2-type macrophages were increased, and M1/M2 was decreased (P<0.05). 【Conclusion】 NAR may promote the M2-type differentiation of macrophages stimulated by high glucose by down-regulating RhoA/ROCK signaling pathway.

Infectious disease is a kind of disease that can be transmitted between humans and animals. Respiratory infectious diseases are more likely to cause outbreaks through droplet transmission. Coronavirus has repeatedly caused global public health events. Initial symptoms of the infected patients were mild, and the onset of the disease was hidden, but some patients suddenly get worse in a short time, and eventually died due to multiple organ failure. Studies have found that cytokine storms caused by patients′ excessive immune response was one of the important causes of death in the infected patients.

Kidney disease(KD)is a major challenge for global public healthcare systems. Traditional biomarkers(such as serum creatinine and urea)for measuring kidney function are not sufficient sensitivity and specificity.They are not only affected by many factors,but also were only increase significantly in severe KD.Therefore,more sensitive biomarkers for evaluation of KD is essential. Metabolomics is a promising tool that identify non-targeted,global small-molecule metabolite profiles of complex samples,such as biofluids and tissues extract.The application of metabolomics in KD studies has developed rapidly in the past years.Many benefits have been shown from the use of metabolomics in identifying biomarkers for KD.In particular,metabolomic approaches have the potential to diagnose KD with a higher accuracy than traditional diagnostic methods.Metabolomics in KD research has been expanded from experimental study into clinical applications.

Objective To investigate the diagnostic value of serum complement component 1 q (C1q), cystatin C (CysC), neutrophil gelatinase-associated lipocalin (NGAL), creatinine (SCr) and urea (SUr) for early diabetic kidney disease.Methods A retrospective study was conducted in 530 subjects who visited or received physical examination in Mianyang Central Hospital from March 2017 to November 2017. Of these, 229 patients with diabetes mellitus (DM group) were divided into simple diabetes mellitus group (SDM group,n=100) and early diabetic kidney disease group (EDKD group,n=129) respectively, and 301 subjects were selected as the healthy control (HC group).The levels of serum C1q, CysC, NGAL, SCr and SUr were detected in all subjects .Then, the diagnostic values of single and combined detection of these indexes for early diabetic kidney disease were evaluated .The statistical difference among the observed indexes of each group were compared by one-way ANOVA, and the diagnostic performance of those indexes were evaluated by receiver operating characteristic curve ( ROC) analysis.Results The median of serum C1q,CysC,NGAL and SCr in early diabetic kidney disease group were 187.80 mg/L, 1.02 mg/L, 148.70μg/L and 72.00μmol/L.The simple diabetes mellitus group were 177.00 mg/L, 0.80 mg/L, 116.20μg/L and 55.35 μmol/L.The healthy control group were 163.60 mg/L, 0.75 mg/L, 104.20μg/L and 59.40μmol/L. Compared with simple diabetes group ( t1 values were 6.50, 9.44, 3.87,9.19 and 4.34, P<0.05)and healthy control group(t2 values were 7.26, 12.54, 5.86,6.16 and 6.49, P<0.05),the levels of serum C1q, CysC, NGAL, SCr and SUr in diabetic kidney disease group were significantly increased . According to the ROC curve analysis , the diagnostic performance of CysC ( AUC=0.837 ) was much higher than those of C1q(AUC=0.731), NGAL(0.742)and SCr(AUC=0.720)for early diabetic kidney disease by using single detection.Otherwise, combined the diagnostic performance of joint detection reached the better when combined C1q and CysC (AUC =0.890,Se =79.1％, Sp =86.5％, YI =0.656).While increase detection of NGAL (z=1.817, P>0.05) or NGAL+SCr (z=1.806,P>0.05) did not further improve the diagnosis performance of early diabetic kidney disease .Conclusions C1q, CysC and NGAL with equal diagnostic performances are superior to SCr and SUr in diagnosis of early diabetic kidney disease . Among them, the combined detection of C1q and CysC has better diagnostic performance for early diabetic kidney disease.
