Clinical features and laboratory data analysis of decreased glycosylated hemoglobin related to hemolytic disease / 中华血液学杂志

Objective@#To compare the effects of different hemolytic diseases on the level of glycosylated hemoglobin (HbA1c) to further explore the relationship between HbA1c and laboratory indexes to disclose implications of HbA1c in hemolytic diseases.@*Methods@#The distribution of 192 decreased HbA1c cases in 4 categories of hemolytic diseases was analyzed. Laboratory indexes related to hemolysis were tested and analyzed in each kind of disease, and relationship between laboratory indexes and HbA1c was statistically explored.@*Results@#Diagnoses of decreased HbA1c cases mainly included erythrocyte membranopathies (88 cases), immunohemolytic anemia (72 cases), hemoglobinopathy (4 cases) and erythrocyte enzymopathy (5 cases). The distribution of HbA2 and normal HbF subjects in immunohemolytic anemia and hemoglobinopathy was significantly different from those of HbA2 and / or abnormal HbF subjects (41.7% vs 22.0%, χ2=5.574, P=0.018; 0.7% vs 7.3%, P=0.031). Compared with non-hemolytic disease patients, those who suffered from 4 categories of hemolytic diseases showed lower HbA1c level and higher reticulocyte percentage (Ret), indirect bilirubin (IBIL) and free hemoglobin (F-Hb). Different levels of Ret, reticulocyte hemoglobin content (Ret-He), mean corpuscular volume (MCV), IBIL and F-Hb among the 4 kinds of diseases were observed, but the causes of the differences were not the same. HbA1c was negatively correlated with other laboratory indexes in erythrocyte membranopathies and immunohemolytic anemia.@*Conclusions@#Hemolytic disease resulted in false lower HbA1c, but impact of difference on HbA1c between different diseases was not significant. HbA1c was closely connected to laboratory indexes related to hemolysis, which might have potential implications for hemolytic diseases such as erythrocyte membranopathies and immunohemolytic anemia.

Effect of propofol on gap junction function of BRL-3A cells and cisplatin-induced toxicity to rat hepatic BRL-3A cells / 中华麻醉学杂志

Objective To investigate the effect of propofol on the gap junction function of BRL-3A cells and cisplatin-induced toxicity to rat hepatic BRL-3A cells. Methods Rat hepatic BRL-3A cell line was provided by professor Tao laboratory of department of pharmacology of our university and cultured in DMEM liquid culture medium at 37℃. The cells were randomly divided into 6 groups: group Ⅰ control (group C) ; group Ⅱ was exposed to intralipid (the solvent) 10 μg/ml (group Ⅰ) ; group Ⅲ was exposed to oleamide (gap junction function inhibitor) 25 μmol/L (group O) and group Ⅳ ,Ⅴ , Ⅵ were exposed to propofol l.5, 2.8 and 4.1 μg/ml respectively (groups P1, 2,3) . Using parachute dye-coupling assay, the dye spread rate and inhibition rate were calculated to measure the gap junction function of BRL-3 A cells. BRL-3 A cells were seeded in two different densities:high density group (seeding density = 1×105 /ml) and low density group (seeding density = 500/ml). Both groups were further divided into 5 subgroups: subgroup Ⅰ control; subgroup Ⅱ was exposed to cisplatin 2.5 μmol/L and subgroup Ⅲ ,Ⅳ ,Ⅴ were exposed to cisplatin 2.5 μmol/L + intralipid 10 μg/ml or oleamide 25 μmol/L or propofol 2.8 μg/ml respectively. The effect of propofol on the cytotoxicity of cisplatin was evaluated by standard colony-forming assay. Results The dye spread rate was significantly lower and inhibition rate higher in groups O,P1 , P2 and P3 than in group C. Propofol decreased the dye spread rate and increased inhibition rate in a concentration-dependent manner. Propofol and oleamide significantly increased colony formation rate in high density group,but had no significant effect on colony formation rate in low density group. Conclusion Propofol can inhibit the gap junction function of BRL-3A cells in a concentration-dependent manner and reduce cisplatin-induced cytotoxicity by inhibiting gap junction function.

Objective To investigate the effect of propofol on the function of gap junction (GJ) in HeLa cells transfected with Cx32/Cx26 plasmid. Methods Cervical cancer HeLa cells transfected with Cx32/Cx26 was given as present by professor Andrew L. Harris from New Jersey Dental Medical School, department of pharmacology and physiology. The transfected cells were selected by G-418. The effective GJ channels were identified by "Parachute Assay". The cells were randomly divided into 6 groups: Ⅰ control group (group C); Ⅱ fat emulsion group was exposed to fat emulsion 10 μg/ml (group E); Ⅲ 18-α-GA group was exposed 18-α-GA (gap junction blocker) 1.0 μg/ml (18-α-GA); Ⅳ, Ⅴ, Ⅵ propofol groups were exposed to propofol 1.3, 2.2 and 3.2μg/ml respectively (group P1, P2, P3). The transfected HeLa cells were incubated at 37 ℃ for 4 h. Gap junction function was assessed using fluorescent indicators Calcine-AM which emits green fluorescence and CM-Dil which emits red fluorescence. The small molecular Calcine-AM can pass through gap junction and enters HeLa cells while the large molecular CM-Dil cannot pass through gap junction and stays in the loading cells. Fluorescent indicator transmissibility and inhibition rate were calculated. Results The fluorescent indicator transmissibility was significantly lower and inhibition rate higher in group 18-α-GA, P1, P2 and P3 than in control group. There was nosignificant difference in the fluorescent indicator transmissibility and inhibition rate between group C and E. The inhibition of GJ function by propofol was dose-dependent. Conclusion Propofol can inhibit the function of GJ in HeLa cells transfected by Cx32/Cx26 in a dose-dependent manner.
