Anidulafungin is an effective antifungal medicine, which can inhibit activities of candida in vitro and in vivo. Echinocandin B (ECB) is the key precursor of Anidulafungin, thus the price and market prospect of Anidulafungin is directly due to the fermentation titer of ECB. In this study, Aspergillus nidulans was used for ECB fermentation, and the influence of adding microparticles on ECB fermentation was studied, such as talcum powder, Al2O3, and glass beads. The particle size and concentration were the key factors for mycelium morphology and ECB production, and ECB production could reach 1 262.9 mg/L and 1 344.1 mg/L by adding talcum powder of 20 g/L (d50 = 14.2 μm) and 7 glass beads (6 mm), an increase by 33.2% and 41.7%, respectively. The results indicated that the mycelium morphology of filamentous microorganisms and the product yield of fermentation could be improved by adding microparticles remarkably, and it provide an important method for the fermentative optimization of filamentous microorganisms.

Objective:To investigate the relationship between serum 25(OH)D and SIRT4 levels and glycolipid metabolism in children with different levels of obesity.Methods:A total of 124 children with different levels of obesity who received treatment in Shaoxing Women's and Children's Health Care Hospital from February 2016 to February 2021 were included in this study. These children were divided into mild/moderate obesity group ( n = 76) and severe obesity group ( n = 48) according to body mass index. An additional 62 healthy children who concurrently received a physical examination were selected for controls. The general data of all children were collected. The relationship between the factors that affect obesity in children and serum 25(OH)D and SIRT4 levels and glycolipid metabolism was analyzed. Results:In the control, mild/moderate obesity, and severe obesity groups, body mass was (26.68 ± 4.98) kg, (33.24 ± 5.48) kg, (37.18 ± 5.88) kg, respectively; waist circumference was (56.12 ± 4.62) cm, (68.45 ± 5.20) cm, (79.34 ± 5.65) cm, respectively; hip circumference was (68.42 ± 5.08) cm, (72.45 ± 6.45) cm, (80.56 ± 6.95) cm, respectively; body mass index (BMI) was (15.90 ± 2.04) kg/m 2, (23.58 ± 2.45) kg/m 2, (25.89 ± 2.35) kg/m 2], respectively; fasting insulin (FINS) level was (26.65 ± 3.68) pmol/L, (34.82 ± 4.15) pmol/L, (48.56 ± 5.49) pmol/l, respectively; homeostasis model assessment of insulin resistance (HOMA-IR) was (1.06 ± 0.24), (2.12 ± 0.35), (3.84 ± 0.52), respectively; total cholesterol (TC) level was (2.21 ± 0.45) mmol/L, (4.14 ± 0.58) mmol/L, (5.96 ± 0.64) mmol/L, respectively; triacylglycerol (TG) level was (0.68 ± 0.16) mmol/L, (1.12 ± 0.24) mmol/L, (1.56 ± 0.35) mmol/L, respectively; low density lipoprotein cholesterol (LDL-C) was (2.68 ± 0.42) mmol/L, (2.10 ± 0.32) mmol/L, (1.41 ± 0.25) mmol/L, respectively; high density lipoprotein cholesterol (HDL-C) was (1.98 ± 0.42) mmol/L, (3.12 ± 0.51) mmol/L, (4.10 ± 0.56) mmol/L, respectively. There were significant differences in body mass, waist circumference, hip circumference, BMI, FINS, HOMA-IR, TC, TG, HDL-C, and LDL-C among the three groups ( F = 53.62, 280.42, 53.33, 303.44, 338.48, 755.71, 618.75, 165.81, 186.89, 251.42, all P < 0.001). Body mass, waist circumference, hip circumference, BMI, FINS, HOMA-IR, TC level, TG level, HDL-C level, and LDL-C level were lower in the control group than in the mild/moderate obesity group ( t = -7.28, -14.56, -4.00, -19.72, -6.49, -21.45, -12.36, 9.20, -14.12, all P < 0.05). Body mass, waist circumference, hip circumference, BMI, FINS, HOMA-IR, TC, TG, HDL-C and LDL-C were lower in the mild/moderate obesity group than in the severe obesity group ( t = -3.79, -10.98, -6.61, -5.19, -15.81, -22.02, -16.34, -8.30, 12.68, -10.03, all P < 0.05). Serum 25(OH)D [(60.52 ± 8.95) nmol/L vs. (49.88 ± 8.12) nmol /L, t = 7.31, P < 0.05] and SIRT4 [(1.98 ± 0.38) mmol/L vs. (1.06 ± 0.30) mmol/L, t = 15.89, P < 0.05] levels were significantly greater in the control group than in the mild/moderate obesity group. Serum 25(OH)D [(49.88 ± 8.12) nmol/L vs. (41.62 ± 7.50) nmol /L, t = 5.68, P < 0.05] and SIRT4 [(1.06 ± 0.30) mmol/L vs. (0.52 ± 0.15) mmol/L, t = 11.57, P < 0.05] levels were significantly greater in the mild/moderate obesity group than in the severe obesity group. Multiple linear regression analysis showed that body mass, waist circumference, hip circumference, FINS, HOMA-IR, TC, TG, and LDL were the positive influential factors of childhood obesity ( B = 0.170, 0.310, 0.403, 1.000, 3.464, 2.080, 2.656, 4.324); HDL, serum 25(OH)D and SIRT4 were the negative influential factors of childhood obesity ( B = -2.096, -0.156, -6.615). Pearson correlation analysis showed that serum 25(OH)D was significantly negatively correlated with FINS, HOMA-IR, TC, TG and LDL ( r = -0.20, -0.46, -0.30, -0.36, all P < 0.01), and significantly positively correlated with FPG and HDL ( r = 0.43, 0.77, both P < 0.01). Serum SIRT4 was negatively correlated with FINS, TC, TG, and LDL ( r = -0.48, -0.74, -0.61, -0.64, all P < 0.01), and positively correlated with FPG and HDL ( r = 0.21, 0.84, both P < 0.01). Conclusion:Serum 25(OH)D and SIRT4 levels decrease with the aggravation of obesity in children and are closely related to glycolipid metabolism. Therefore, early detection of obesity can reflect the degree of obesity and glycolipid metabolism in children.

Objective:To investigate the correlation between triglyceride-glucose (TyG) index and high on-treatment platelet reactivity (HTPR) during clopidogrel treatment in patients with ischemic stroke.Methods:Patients with ischemic stroke who received maintenance dose of clopidogrel (75 mg/d) in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2017 to March 2021 were retrospectively included. The highest quartile (Q4) of the TyG index was defined as insulin resistance. Platelet reactivity was assessed by thromboelastogram and clopidogrel HTPR was defined as the clot strength induced by adenosine diphosphate (MA ADP) >47 mm. Multivariate regression model was used to analyze the independent correlation between TyG index and platelet reactivity. Results:A total of 83 patients were included. The TyG index showed a linear correlation with MA ADP. The patients were divided into 4 groups according to the quartile of TyG index. The incidence of clopidogrel HTPR increased significantly with the increase of the quartile of the TyG index ( Ptrend=0.017). Multivariate analysis showed that there was a significant independent correlation between insulin resistance and clopidogrel HTPR (odds ratio 4.597, 95% confidence interval 1.285-16.446; P=0.019). Conclusions:In patients with ischemic stroke treated with clopidogrel, the incidence of clopidogrel HTPR gradually increases with the increase of the quartile of the TyG index. The insulin resistance assessed by the TyG index is independently associated with clopidogrel HTPR.
