Objective:To explore the impact and biological relevance of E3 ubiquitin ligase MARCH2 on the degradation of low-density lipoprotein receptor(LDLR)in hepatic cell lines.Methods:The ubiquitin ligase of the MARCH family involved in LDLR degradation was predicted using databases, and their binding sites were predicted through molecular docking.The association between MARCH2 and cholesterol levels was screened through a literature search.Various experiments including real-time quantitative PCR, immunoblotting, cycloheximide tracing assay, immunoprecipitation, were conducted in hepatic cell lines to investigate the impact of MARCH2 on the ubiquitination degradation of LDLR.Additionally, DiⅠ-labeled low-density lipoprotein(DiⅠ-LDL)uptake assays were performed to examine the effect of MARCH2 overexpression on LDL uptake in hepatocytes.Results:Real-time quantitative PCR, immunoblotting, and cycloheximide tracing experiments illustrated that MARCH2 facilitates the degradation of LDLR at the protein level rather than the transcriptional level.MARCH2 degraded 13% to 33% of LDLR protein within 24 hours, Following serum starvation and subsqnent serum refeeding, the degradation level significantly increased( t=2.280, P=0.046).This degradation process was unaffected by the proteasome pathway inhibitor MG132 but was hindered by the lysosome inhibitor chloroquine.Immunoprecipitation experiments validated the interaction between MARCH2 and LDLR.DiⅠ-LDL uptake experiments showed that MARCH2 overexpression decreased LDL uptake by hepatocytes from 4 039.8±16.2 to 2 630.3±185.9 at 3 hours, indicating a 34.9% reduction( t=16.89, P<0.001). Conclusions:MARCH2 facilitates the degradation of LDLR via the ubiquitin-dependent lysosome pathway, thereby decreasing the uptake of LDL by hepatic cells.

OBJECTIVE:
This study prospectively investigates the association between immunoglobulin G (IgG) N-glycan traits and ischemic stroke (IS) risk.
METHODS:
A nested case-control study was conducted in the China suboptimal health cohort study, which recruited 4,313 individuals in 2013-2014. Cases were identified as patients diagnosed with IS, and controls were 1:1 matched by age and sex with cases. IgG N-glycans in baseline plasma samples were analyzed.
RESULTS:
A total of 99 IS cases and 99 controls were included, and 24 directly measured glycan peaks (GPs) were separated from IgG N-glycans. In directly measured GPs, GP4, GP9, GP21, GP22, GP23, and GP24 were associated with the risk of IS in men after adjusting for age, waist and hip circumference, obesity, diabetes, hypertension, and dyslipidemia. Derived glycan traits representing decreased galactosylation and sialylation were associated with IS in men (FBG2S2/(FBG2 + FBG2S1 + FBG2S2): odds ratio ( OR) = 0.92, 95% confidence interval ( CI): 0.87-0.97; G1 n: OR = 0.74, 95% CI: 0.63-0.87; G0 n: OR = 1.12, 95% CI: 1.03-1.22). However, these associations were not found among women.
CONCLUSION
This study validated that altered IgG N-glycan traits were associated with incident IS in men, suggesting that sex discrepancies might exist in these associations.

In line with the significant changes in disease spectrum, the wound healing discipline in China has shown a good momentum of development from budding to rapid growth. At present, improving the connotation of disciplinary development determines the speed and quality of disciplinary development in the future. The characteristics of wound diseases determine that the wound healing discipline must have the following property: standardization, integration, and translation. Here is the initial introduction on the connotation of standardization, collaboration, and translation in clinical practice of wound healing discipline. Besides, the discussions on standardization, integration, and translation in the 13 th National Conference of Wound Repair (Healing) and Tissue Regeneration were summarized. It is expected that these achievements can be reflected and improved in the construction of the wound healing discipline in China.

The association among plasma trimethylamine-N-oxide (TMAO), FMO3 polymorphisms, and chronic heart failure (CHF) remains to be elucidated. TMAO is a microbiota-dependent metabolite from dietary choline and carnitine. A prospective study was performed including 955 consecutively diagnosed CHF patients with reduced ejection fraction, with the longest follow-up of 7 years. The concentrations of plasma TMAO and its precursors, namely, choline and carnitine, were determined by liquid chromatography-mass spectrometry, and the FMO3 E158K polymorphisms (rs2266782) were genotyped. The top tertile of plasma TMAO was associated with a significant increment in hazard ratio (HR) for the composite outcome of cardiovascular death or heart transplantation (HR = 1.47, 95% CI = 1.13-1.91, P = 0.004) compared with the lowest tertile. After adjustments of the potential confounders, higher TMAO could still be used to predict the risk of the primary endpoint (adjusted HR = 1.33, 95% CI = 1.01-1.74, P = 0.039). This result was also obtained after further adjustment for carnitine (adjusted HR = 1.33, 95% CI = 1.01-1.74, P = 0.039). The FMO3 rs2266782 polymorphism was associated with the plasma TMAO concentrations in our cohort, and lower TMAO levels were found in the AA-genotype. Thus, higher plasma TMAO levels indicated increased risk of the composite outcome of cardiovascular death or heart transplantation independent of potential confounders, and the FMO3 AA-genotype in rs2266782 was related to lower plasma TMAO levels.

Objective: To explore the epidemiological characteristics and treatment outcomes of patients with hydrofluoric acid burns in hands. Methods: A retrospective observational study was conducted. The medical records of 229 patients with hydrofluoric acid burns in hands who were admitted to Zhejiang Quhua Hospital from January 2008 to December 2020 and met the inclusion criteria were collected. The following statistical data of patients were collected, including gender, age, type of affiliated enterprise, hydrofluoric acid mass fraction, injury site, total burn area, prehospital time, length of hospital stay, length of wound healing, whether hypocalcemia and hypomagnesemia occurred or not on admission, whether surgery intervention was performed or not, and whether scar sequelae occurred or not. Single factor and multivariate logistic regression analysis were used to screen out the risk factors impacting surgery intervention and scar sequelae of all the patients and patients whose hydrofluoric acid mass fraction was known. Single factor and multivariate linear regression analysis were used to screen out the risk factors impacting the length of wound healing of all the patients and patients whose hydrofluoric acid mass fraction was known. Results: The 229 patients included 206 males and 23 females, with the majority aged 30 to 50 years (139 patients). The type of affiliated enterprise of majority patients was non-fluorine chemical enterprise. The hydrofluoric acid mass fraction was known in only 91 patients, mainly medium. The majority injury site was in the middle and end of finger. The total burn area was below or equal to 1% total body surface area. The prehospital time was 19 (9, 29) h. The length of hospital stay was 2 (1, 7) d. The length of wound healing was 12 (8, 18) d. The proportions of hypocalcemia and hypomagnesemia were 0.9% (2/229) and 1.3% (3/229) on admission, respectively. Thirty-six patients had surgeries and 83 patients had scar sequelae. In 229 patients, single factor logistic regression analysis showed that both type of affiliated enterprise and prehospital time were the factors impacting surgery intervention (with odds ratio values of 7.86 and 51.35, respectively, 95% confidence intervals of 1.83-33.76 and 11.89-221.78, respectively, P<0.01) and scar sequelae of patients (with odds ratio values of 3.62 and 27.40, respectively, 95% confidence intervals of 1.76-7.43 and 13.25-56.68, respectively, P<0.01); multivariate logistic regression analysis showed that prehospital time was the independent risks factor impacting surgery intervention and scar sequelae of patients (with odds ratio values of 43.00 and 24.55, respectively, 95% confidence intervals of 9.89-187.03 and 11.78-51.16, respectively, P<0.01); single factor linear regression analysis showed that both type of affiliated enterprise and prehospital time were the factors impacting the length of wound healing of patients (with β values of 6.16 and 12.83, respectively, 95% confidence intervals of 3.38-8.93 and 10.72-14.93, respectively, P<0.01); multivariate linear regression analysis showed that both type of affiliated enterprise and prehospital time were the independent risk factors impacting the length of wound healing of patients (with β values of 2.81 and 12.16, respectively, 95% confidence intervals of 0.50-5.13 and 10.00-14.31, respectively, P<0.05 or P<0.01). In 91 patients whose hydrofluoric acid mass fraction was known, single factor logistic regression analysis showed that type of affiliated enterprise, hydrofluoric acid mass fraction (low and high), and prehospital time were all the factors impacting surgery intervention of patients (with odds ratio values of 9.10, 11.25, 10.69, and 0.04, respectively, 95% confidence intervals of 1.15-72.25, 1.39-90.93, 1.32-86.59, and 0.01-0.19, respectively, P<0.05 or P<0.01), type of affiliated enterprise, hydrofluoric acid mass fraction, and prehospital time were all the factors impacting scar sequelae of patients (with odds ratio values of 0.32, 0.21, and 36.80, respectively, 95% confidence intervals of 0.11-0.92, 0.06-0.73, and 11.03-122.79, respectively, P<0.05 or P<0.01); multivariate logistic regression analysis showed that both hydrofluoric acid mass fraction and prehospital time were the independent risk factors impacting surgery intervention of patients (with odds ratio values of 11.51 and 0.04, respectively, 95% confidence intervals of 1.22-108.26 and 0.01-0.25, respectively, P<0.05 or P<0.01), prehospital time was the independent risk factor impacting scar sequelae of patients (odds ratio=37.71, with 95% confidence interval of 9.97-142.69, P<0.01); single factor linear regression analysis showed that type of affiliated enterprise, hydrofluoric acid mass fraction (low and high), and prehospital time were all the factors impacting the length of wound healing of patients (with β values of 7.12, -5.63, -9.74, and 13.50, respectively, 95% confidence intervals of 2.43-11.81, -10.59--0.68, -14.78--4.70, and 10.14-16.86, respectively, P<0.05 or P<0.01); multivariate linear regression analysis showed that both hydrofluoric acid mass fraction and prehospital time were the independent risk factors impacting the length of wound healing of patients (with β values of -5.84 and 0.09, respectively, 95% confidence intervals of -10.59--1.08 and 0.05-0.12, respectively, P<0.05 or P<0.01). Conclusions: The majority of patients with hydrofluoric acid burns in hands are young and middle-aged males. Type of affiliated enterprise, hydrofluoric acid mass fraction and prehospital time are the risk factors that affect the treatment outcomes of patients with hydrofluoric acid burns in hands.

Objective:To explore the protective effect and the mechanism of Danggui Shaoyaosan(DSS) on angiotensin Ⅱ (AngⅡ)/transient receptor potential cation channel 6 (TRPC6) pathway in nephrotic syndrome (NS) rats. Method:In animal experiments, doxorubicin (4 mg·kg-1 for the 1st week and 2 mg·kg-1 for the 2nd week) was injected twice to the tail vein of rats to induce NS model in 160 rats, which were then randomly divided into model group (normal saline), losartan group (30 mg·kg-1·d-1), and low-(4.3 g·kg-1·d-1), medium-(8.6 g·kg-1·d-1), and high-dose (17.2 g·kg-1·d-1) DSS groups. Besides, a normal group was also set. After intervention for four weeks, ultrastructure changes of the kidney were identified by transmission electron microscopy (TEM). The 24-hour urine protein was detected by kits. Radioimmunoassay was used to detect the content of AngⅡ and Calcineurin (CaN) in plasma. Western blot was used to detect the protein expression of TRPC6, angiotensin Ⅱ type 1 receptor (AT1R), podocyte slit diaphragm-specific protein (Nephrin), and cysteine-aspartic acid protease-3 (Caspase-3) in the renal cortex. Immunohistochemistry was used to detect the expression of TRPC6 and AT1R in the slit diaphragm. In cell experiments, AngⅡ stimulated MPC5 podocytes. The cells were randomly divided into a normal group, an AngⅡ group, an AngⅡ+SAR7334 (TRPC6-specific inhibitor) group, an AngⅡ+5%DSS group, an AngⅡ+10%DSS group, and an AngⅡ+15%DSS group. Western blot was used to detect the protein expression of TRPC6, AT1R, Nephrin, and Caspase-3 in podocytes. Result:Compared with the normal group, the model group showed increased 24-hour urine protein content (
