Adrenal myelolipoma with congenital 17a-hydroxylase deficiency: a pedigree report and review of the literature / 中华内分泌代谢杂志

Objective To analyse the clinical and pathological characteristics of congenital adrenal hyperplasia (CAH) with adrenal myelolipoma (AML),and to improve the awareness of CAH.Methods The P450c17a gene in a pedigree with CAH and the clinical and pathological characteristics of three sisters of the pedigree with CAH and adrenal myelolipoma were studied;and the pertinent literatures reported abroad were analyzed and summarized.Results (1) A heterozygous point mutation 1178 base A to T in exon 6,and a heterozygous deletion mutation 1 457-1 465 bases TCGACTCTT of exon 8 were detected in P450c17 (CYP17) gene of three sisters of the pedigree with CAH.(2) The clinical characteristics of three sisters were hypertension,hypokalemia,primary amenorrhea,and gonadal dysgenesis.Without regular treatment after the diagnosis of CAH,the three sisters experienced many years of elevated serum ACTH levels,and developed AML.Conclusion The long-term high ACTH level plays an important role in the development of AML,although the exact mechanism of CAH with adrenal myelolipoma remains still unclear.CAH patients require long-term regular treatment.

Effects of collagen matrices by covalent incorporation of heparin and loading with huangqi injection (HI) on anagenetic blood vessel / 中国中药杂志

To investigate effects of collagen matrices by covalent incorporation of heparin and loading with huangqi injection (HI) on anagenetic capillaries, we established the chick chorioallantois model. The collagen matrices by covalent incorporation of heparin and loading with HI were placed and then the eggs were continuously incubated for 3 days. The number of capillaries in the vicinity of samples, the hemoglobin content inside the samples, the dry weight and the macroscopic observation were evaluated. We found the heparinized matrices had comparable angiogenic effects. The number of capillaries, the hemoglobin content, the expression of CD34 increased remarkably (P < 0.01). So we concluded that HI might be considered as an alternative or addition agent to promote the acidification of capillaries.

Effect of Astragalus Injection on Aquaporin-1 Expression of Peritoneal Mesothelial Cells in Rats with Peritoneal Dialysis / 广州中医药大学学报

Objective To observe the effect of Astragalus Injection(AI) on aquaporin-1(AQP-1) expression of peritoneal mesothelial cells in rats with peritoneal dialysis.Methods Twenty-five male SD rats were divided into the normal control group(N =7),model group(N =9) and AI group(N =9).Except the normal control group,the model group was given intraperitoneal injection of peritoneal dialysate(containing glucose 42.5 g/L),and AI group was given intraperitoneal injection of peritoneal dialysate(containing glucose 42.5 g/L) plus AI(20 mg/mL),25mL/d for 10 continuous days.On the 11th day of experiment,the amount of dialysis ultrafiltration(UF) and net UF,and the concentration ratio of dialysate and plasma sodium(D/PNa) were measured,peritoneal pathological changes were observed with light microscope,and the expression of AQP-1 in peritoneal mesothelial cells was detected with immunohistochemical method.Results When the peritoneal dialysate was kept in the abdominal cavity for 60 min,the amount of UF and Net UF was increased in AI group(P
