Objective To investigate the relationship between thyroid function indexes and plasma level of N-terminal pro-brain natriuretic peptide (NT-proBNP) among patients who had high risks for cardiovascular diseases without thyroid diseases and heart failure.Methods Totally 166 elderly type 2 diabetic patients aged 80 years and over with normal range of thyroid stimulating hormone (TSH) were divided into group of euthyroid sick syndrome (ESS,n=62) and group of normal thyroid hormones (NESS,n=104).The patients in normal thyroid hormones group were divided into three subgroups according to the levels of total triiodothyronine (TT3),(low-level group,n=26; middle-level group,n=50; high-level group,n=28).Levels of thyroid hormones,NT-proBNP,cholesterol,low-density lipoprotein cholesterol,fibrinogen,HbA1C,glomerular filtration rate (eGRF),left ventricular ejection fraction (LVEF) and the incidences of concomitant diseases were measured and detected.lgNT-proBNP was used to calculated after NT-proBNP was changed by Log transformation.Results Compared with NESS group,ESS group showed that age was increased,systolic pressure and LVEF were decreased [(86.3 ± 5.8) years vs.(85.6 ± 5.2) years,(126.6±15.5) mmHg vs.(135.6±17.8) mmHg,(63.9±7.6)％ vs.(67.4±7.5)％,all P＜0.01].Compared with NESS group,ESS group showed that the levels of serum total T3 and free T3 were decreased [(0.89±0.17) nmol/L vs.(1.45±0.31) nmol/L,(3.31±0.55) pmol/L vs.(3.96± 0.59) pmol/L,both P＜0.01].The lgNT-proBNP level was higher and serum total thyroxine (TT4) level was lower in ESS group than in NESS group [(2.40±0.40) ng/L vs.(2.26±0.44) ng/L,(101.80±36.11) nmol/L vs.(111.07±23.29) nmol/L,both P＜0.05].Pearson analysis revealed that serum levels of TT3,TT4 and FT3 were negatively correlated with lgNT-proBNP (r=-0.217,-0.180,-0.174,respectively,all P＜0.05) after adjustment for age,systolic pressure and LVEF.Stepwise regressive analysis showed TT3 was the risk factors for lgNT-proBNP (β=-0.267,P＜ 0.01).Compared with the low-level group,the lgNT-proBNP were significantly reduced in the middle-,and high-level groups [(2.19±0.42) ng/L,(2.19±0.46) ng/L vs.(2.44±0.39) ng/L,both P＜0.05].Conclusions TT3 has a close correlation with NT-proBNP in elderly type 2 diabetic patients with normal TSH.It has a significant meaning to test TT3 level for monitoring heart function in clinical medicine.

Royal jelly (2.5g/kg/d igX8d) increased the clearance rate of iv charcoal particles in normal mice, and completely antagonized the decrease of clearance rate caused by cortisone acetate. It also potentiated the delayed type hypersensitivity ( DTH ) reaction of footpad induced by SRBC in normal mice, and entirely antagonized the inhibition of DTH reaction caused by eye lophosphamide. Royal jelly (2.5 g/kg/d ig X 7 d ) had no marked influence on hemolysin formation in normal mice and immunosuppressed mice caused by eye lophosphamide.

Purpose:To clarify the association between renal cysts and renal cell carcinoma (RCC), we analyzed the clinical characteristics of patients with renal cell carcinoma and renal cyst. Methods:From May 1996 to January 2004, a total of 198 patients were hospitalized for renal cell carcinoma in our department, and 64 patients had both renal cysts and renal cell carcinoma (RCC). The clinical characteristics of the 64 patients were evaluated, and compared to 106 renal cell carcinoma (RCC)patients without renal cysts from the 198 patients in the same period. Results:Renal cysts were identified by preoperative ultrasonography, computerized tomography and magnetic resonance imaging in 37%(22/59)、24%(15/61) and 35%(6/17) respectively. Histopathological examination revealed renal cyst in 15 patients (23%). The sizes of renal cyst were 0.5 to 12 cm. The pathological examinations showed clear cell carcinoma in 61, chromophilic cell carcinoma in 2 and a combined type of clear cell carcinoma and chromophilic cell carcinoma in 1. Compared to RCC patients with those without renal cyst,younger and male RCC patients were easier to also have with renal cyst(P

Objective To construct the third-generation self-inactivating lentiviral vectors including BMP-2,BMP-4,BMP-6,BMP-7,BMP-9 and Wnt3a,then integrate them into the genome of mouse embryonic osteoblast cell,MC3T3-E1,and to explore the capability of osteogenic differentiation of individual bone morphogenetic control factor and the effective approaches to further improve the capability of osteogenic differentiation.Methods The plasmid vectors of gene expression including BMP-2,BMP-4,BMP-6,BMP-7,BMP-9 and Wnt3a were constructed,which were identified through enzyme cutting and further confirmed through sequencing.After packing pELNS-BMP-2,BMP-4,BMP-6,BMP-7,BMP-9 and Wnt3a,mouse embryonic osteoblast cell,MC3T3-E 1 was transfected,and the transfection efficiency was confirmed by GFP fluorescence imaging.The expression level of Runx2 mRNA and the transfection efficiency of individual bone morphogenetic control factor was detected by Real time PCR.Eight groups of MC3T3-E1 were dual-gene co-transfected,and the transfection efficiency was verified by GFP fluorescence imaging.ELISA was adopted to detect the expression level of BGP and ALP in MC3T3-E1culture supernatants;Real time PCR was adopted to detect the expression level of Runx2 mRNA;Western blot was adopted to detect the expression level of protein of BMP-2,BMP-4,BMP-6,BMP-7,BMP-9 and Wnt3a.Thus,the effectiveness of osteogenic differentiation of dual-gene co-transfection were evaluated.Results The recombination of lentiviruses,pELNS-BMP-2,pELNS-BMP-4,pELNS-BMP-6,pELNS-BMP-7,pELNS-BMP-9 and pELNS-Wnt3a were successfully constructed.MC3T3-E1 was successfully transfected.The expression levels of Runx2 mRNA were:BMP-2 ＞ BMP-4 ＞ BMP-9 ＞ BMP-7 ＞ Wnt3a ＞ BMP-6.Successful transfection of the dual-gene co-transfection of eight groups of MC3T3-E1 were verified by GFP fluorescence imaging.The expression level of Runx2 mRNA,the expression of BGP and ALP showed BMP-2 and BMP-7 co-transfection group was the most efficient in osteogenesis transfection.Western blot revealed thatthe protein expression of BMP-2,BMP-4,BMP-6,BMP-7,BMP-9 and Wnt3a increased after cotransfection of MC3T3-E1 by BMP-2 and BMP-7.Conclusion The third-generation lentiviral vector,pELNS can lead BMP-2,BMP-4,BMP-6,BMP-7,BMP-9 and Wnt3a into MC3T3-E1,mouse embryonic osteoblast cell,and stabilize its expression.Individual bone morphogenetic control factors can promote MC3T3-E1's differentiation to osteoblasts.The dual-gene co-transfection of BMP-2 and BMP-7 can effectively promote osteoblast conversion,which provides significant theoretical basis and technical support for remodeling of tissue engineering bone.

Objective To investigate the effect of a single or combined transplantation of the neural stem cells(NSCs) modified with gene of NGF or GDNF on the cholinergic neurons of basal forebrain of AD model rat. Methods The NSCs modified with gene of NGF or GDNF were implanted in single or combined into the lateral cerebral ventricle of the rats after fibria\|fornix transection.The rats were killed three weeks after transplantation and the brain sections concluding basal forebrain were cut coronally on a freezing microtome and were processed by immunohistochemistry staining with antibodies against ChAT.The numbers of ChAT positive neurons of medial septum(MS) and vertical diagonal band(VDB) were analyzied statistically with one way of Student\|Newman Kaels. Results In MS,the percentages of ChAT positive neurons at the lesion side to the intact side in NGF group was 81% which was significantly higher than that in the lesion group(34%),NSC group(36%) and GDNF group(50%), P 0\^05). Conclusion\ The injury cholinergic neurons can be protected in different extent after a single or combined transplantation of the neural stem cells modified with gene of NGF or GDNF.Among these three groups,greater protection was found in NGF group and NGF+GDNF group,and lesser protection in GDNF group.\;[
