[Summary] The genomic DNA was extracted from peripheral blood leukocyte of the patient with thyroid hormone resistance syndrome and 14 members of his family.The exons 1-10 of thyroid hormone receptor β (TRβ) gene were amplified by PCR.The products of PCR were sequenced directly to detect the gene mutation.The results showed that 3 members of this family were confirmed to have the C→T transition mutation at nucleotide 1 303 site within exon 10 of TRβ gene,and the missense mutation results in the substitution of histidine to tyrosine (H435Y).The heterozygous mutation may lead to the occurrence of thyroid hormone resistance syndrome.

Effects of the extracts from Lapemis hardwickii on RBCs count and Hb content were studied in the both of mice model of which was made by acetylphenyhydrozine (APH) for hemolytic anemia and of by Chinese rubarb for Xue Xu (debility due to blood deficiency). The results showed that counts of red blood cell (RBC) and content of hemoglobin (Hb) of experimental group in hemolytic anemia model mice were higher significatly than that of control gooup in hemoly ticanemia mice. The content of Hb was increased in Xue Xu mice model,but no marked effect on the counts of RBCs. The study showed that the extract could have a better profective effect on red blood cells of hemolytic anemia mice.

In order to solve the difficucties of renaturation and immunogenicity of new bifunctional fusion protein GAD,inclusion bodies of GAD were modified by PEG-maleimide.Conformational changes of the modified GAD were compared by circular dichroism and tryptophan fluorescence spectroscopy.The biological activity was verified by oral glucose tolerance test and lipid scavenging.The results showed that PEG-maleimide completed the specific-point modification of GAD,and improved its refolding efficiency.The secondary and tertiary structures of mPEGylated GAD were consistent with that of GAD.PEG-GAD has significant hypoglycemic and lipid-lowering effects (P ＜0.001) with longer half life in vivo and lower immunogenicity (P ＜0.01).This study provides effective strategies for the development of strongly hydrophobic peptide drugs.

In 2015, American College of Endocrinology ( ACE), American Association of Clinical Endocrinologists ( AACE ) , European Association for the Study of Diabetes ( EASD ) , Chinese Society of Endocrinology, American Diabetes Association ( ADA ) , American Association of Diabetes Educators ( AADE ) , Academy of Nutrition and Dietetics(AND), etc. published several guidelines and statements on diabetes and its complications. The selection of hypoglycemic drugs, diabetes self-management education and support, the characteristics of blood pressure and blood lipid, the efficacy and adverse reaction of hypoglycemic drugs were also suggested and recommended. These guidelines and statements will play key roles in the clinical diagnosis and treatment of diabetes mellitus, which is reviewed in this article.

AIM To study toxicity of Safflor Yellew (SY) for vascular endothelic cell (VEC) and whether SY has antagonistic effect on platelet activating factor (PAF). METHODS Use light microscopical observation and crystal violet colorimetric method to study morphological and bioactivity change of HVEC and EVC 304 after incubated with PAF, SY, SY+PAF, Ginkolide,and Ginkolide+PAF. RESULTS Cultured with PAF 30 minutes, HVEC had histopathological changes: from fusiform, polygond squamous cell to ellipsoid, circular cell , not binding tightly, but separated by wide gap. As cultured with SY+PAF, cell's morphological changes just as same as PAF's group. And its bioactivity had tendency of decline. Either HVEC was incubated with SY (0.571 g?L -1 ) for 30 minutes or EVC 304 cultured with SY(1 143 g?L -1 ) for 4 hours, their morphology and bioactivity had changes. CONCLUSION SY do not inhibit PAF's injury effect. And high concentration SY has toxicity to cultured endothelic cell.

Objective To evaluate the therapeutic results of percutaneous transhepatic stent angioplasty for portal vein stenosis following liver transplant.Methods From 2005 to 2007,7 patients developed portal vein stenosis following liver transplant.Percutaneous transhepatic stent angioplasty of the portal vein was performed in all patients.The therapeutic results were monitored by clinical follow-up and imaging examination.Results In seven patients,the percutaneous transhepatic stents were placed successfully.The follow up period ranged from 3 months to 34 months.Portal venous patency Was maintained in six patients(one patient died due to hepatic arterial thrombosis and ischemic insult to bile duct at three months following the stent placement).No complications due to stent angioplasty occurred.Conclusion Percutaneous transhepatic stent angioplasty is an effective and safe method for treatment of portal vein stenosis following liver transplant.

[Summary] According to urinary albumin excretion rates ( UAER) , 256 patients with type 2 diabete mellitus (T2DM) were divided into normal albuminuria (NA), microalbuminuria (MA), and clinical nephropathy (CN) groups while 108 healthy subjects as control group. The analysis of variance of single factor was applied to examine lipoprotein(a), triglyceride, total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), cystatin C, and homocysteine. The correlations of lipoprotein ( a ) with urinary albumin excretion rate ( UAER ) and glomerular filtration rate ( eGFR ) were analyzed by Pearson correlation analysis. The sensitivities of lipoprotein ( a ) were evaluated in diagnosis of diabetic nephropathy ( DN) by receiver operating characteristic curve. The results showed that lipoprotein ( a) levels in NA, MA, and CN groups were gradually increased, with a significant increase in CN group(P<0. 05). Pearson correlation analysis revealed that lipoprotein (a) was positively correlated with systolic pressure, TC, cystatin C, and UAER(all P<0. 05) and negatively correlated with fasting blood glucose and eGFR (P<0. 05). The area under the ROC curve of lipoprotein(a) was 0. 639, with the sensitivity 66. 4% and specificity 55. 9% in the optimal cutoff value of 8. 41 mg/dl. These results suggest that lipoprotein(a) may serve as an index for monitoring DN based on its better correlation with UAER and eGFR.
