1.~(131)I treatment in hyperthyroid patients with mild hepatic dysfunction
Chinese Journal of Endocrinology and Metabolism 1985;0(02):-
Forty-two hyperthyroid patients with mild hepatic dysfunction were treated with 131I once orally and followed up for 6 months. The changes of hepatic functions (ALT, AST, ALP, A/G) were determined before and after treatment, hepatic function was ameliorated in these patients. The results indicate that 131I-iodine is safe and effective in treating hyperthyroidism with mild hepatic dysfunction.
2.THE EFFECTS OF ?-ELEMENE ON DNA-BINDING SPECIFICITY AND RNA POLYMERASE INHIBITORY ACTIVITY
Chinese Pharmacological Bulletin 1987;0(03):-
?-elemene that is an element of the Essential oil of the Cuicu-ma Wenyujin showed appreciable anticancer ability. The experimental results showed that the RNA polymerase activity was inhibited by ?-elemene at concentrations of 0.0074 mol/L~0.0172 mol/L. The study of thermal denaturation indicated that the Tm of DNA was decreased after adding ?-elemene. The fluorescent analysis of ?-elemene bound to DNA showed that the intensity of fluorescence was increased. The peak of absorption of DNA was shifted from 260 nm to 240 nm after treatment with ?-elemene.

Fibroblast growth factor(FGF)-21 is a novel insulin-independent glucose regulator,and can be a potential therapeutics for treatment of type Ⅱ diabetes.Although FGF-21 was discovered recently,the insight into its biology and therapeutic utility is rapidly evolving.A number of key metabolically-linked molecules and pathways have been suggested to be involved in the mechanism of action of FGF-21,which enables us to renew the understanding of the FGF-21.The aim of this review is to report the update research outcomes.

Objective To investigate the nerve recanalization and the motor function of hind legs after transplantation of BDNF genetically modified neural stem cells(NSCs) at spinal cord injury site in rat. Methods After L4 spinal cord transection of rat, BDNF genetically modified NSCs were transplanted immediately. Retrograde HRP tracing through sciatic nerve were practiced at 1 week, 1 month, 2 month, 3 month after transplantation of BDNF genetically modified NSCs. The morphological changes were observed at section of spinal cord and the motor functions of both hind legs of rat were detected. Results The morphology of the injured spinal cord sections turned better. Retrograde HRP tracing through sciatic nerve showed some HRP positive neurons and nerve fibers at the site of near rostral end of the nearly injured part at one month after transplantation and increased with the time going by. Motor function of hind legs of rats recovered significantly in all transplantation groups. Conclusion BDNF genetically modified NSCs have repairing effect on spinal cord injury in rat.

Objective To observe the changes of the gene expressions at spinal cord injury site of rat after transplantation of BDNF genetically modified neural stem cells(NSCs) so as to provide basic data for the repair of spinal cord injury. Methods The Wistar rats were randomly divided into 4 groups: control group, operation group, NSCs transplantation group, BDNF NSCs transplantation group. Four time points(7 day, 1 month, 2 month, 3 month) were divided for each group. The expressions of ? galactosidase and BDNF, GFAP, NF 200 at the site of spinal cord injury were observed by cell transplantation, X gal histochemistry, immunocytochemistry, in situ hybridization, etc. Results After transplantation of BDNF genetically modified NSCs, some X gal positive cells were found at the sections of spinal cord injury. The expressions of BDNF were strong, especially at 1 week and 1 month post transplantation in transplantation group. The GFAP and NF 200 positive cells were also found at each time point in each group. Conclusion BDNF genetically modified NSCs can survive at the site of spinal cord injury and can strongly express BDNF, suggesting that BDNF genetically modified NSCs can be used as the material for the repair of spinal cord injury.

Objective To explore the correlation between quantitative value of joint bone scan by single photon emission computed tomography (SPECT) and serum bone metabolic markers in patients with active rheumatoid arthritis (RA).Method Clinical data of 60 newly diagnosed RA patients were retrospectively collected in Department of Rheumatology and Immunology from May 2013 to December 2014,including 28 cases with medical history less than 6 months and 32 from 6 months to 2 years.Serum Cterminal telopeptide of type Ⅰ collgen(CTX-Ⅰ)and N-terminal propeptide of type Ⅰ collagen(PINP) were tested by chemiluminesence.SPECT whole body bone and target joint scan before treatment was done.Thirty-nine healthy subjects as control group received ultrasound,electrocardiogram,X-ray,and whole body bone imaging examination.Quantitative values of joint imaging were calculated for the statistical analysis.Result Demographic data between RA group and control group were comparable (P > 0.05),including sample,sex,age and BMI.The joint SPECT value,CTX-Ⅰ and PINP levels were all significantly higher than those of control group (P < 0.01),which were 6.48 ± 1.98 versus 3.73 ± 1.t6;(0.66 ± 0.37) mg/L versus (0.58 ±0.21) mg/L;(46.35 ±28.15) mg/L versus (30.47 ± 13.75) mg/L respectively.Joint SPECT values had positive correlations with serum CTX-Ⅰ levels in all RA patients,as well as PINP in patients with disease duration 6mon-2years.And the according correlation coefficients were 0.513,0.495,0.402 (P < 0.05).But SPECT value had no correlation with CTX-Ⅰ (P =0.081) in patients with disease duration less than 6 mon.The correlation coefficient was 0.336.Conclusion SPECT imaging quantitative values were positively correlated with serum bone metabolic parameters.Thus SPECT imaging alone or combined with bone markers are helpful in diagnosing active RA.

By using the histochemical method, the electron microscopy and biochemical measurement, this study deals with the changes of the innervation of the uterus in tats induced by pregnancy. The results revealed that the adrenergic and cholinergic innervation of the uterus were reduced in advanced pregnancy. The content of noradrenaline(NE), expressed as ng/per gram wet weight was 194.79?2.85 in the control group and 78.56?0.48 in the late pregnancy group (P

Objective To clone the full length staphylococcal protein A(SPA) gene from Staphylococcus aureus (ATCC6538), and subsequently study the gene structure and antibody binding ability.Methods The full length and the functional region of the SPA gene were cloned into pHisSUMO vector respectively, and expressed in E. coli. The full length and the functional fragment of the SPA protein were detected for antibody binding ability and stability. The functional fragment of the SPA protein fused with SUMO was coupled to the CNBr-activated agarose for antibody purification from rabbit serum. Results A variant of the full length SPA gene was cloned, which has been submitted to GenBank (the accession number is EU695225). Two fusion proteins had the same antibody binding ability as the untagged SPA protein. However, the formers was more stable than the latter at the tested conditions. SUMO-SPA conjugated-agarose kept high efficiency for antibody binding. Conclusion To our knowledge, the full length SPA gene of S.aureus(ATCC6538) is a novel variant. The SUMO tag can improve the stability of the functional region of the SPA protein without damaging the antibody binding ability. This fusion protein has been used for antibody purification successfully.

Objective To compare SPECT/CT fusion imaging and MRI in the diagnosis of benign hip lesions. Methods Twenty-two patients suspected avascular necrosis of femoral head with hip discomfort, pain or action limited were analyzed retrospectively. All patients underwent radionuclide bone scan and MR examination within 5 days, and the diagnosis was proved with clinical follow-up. Results Eighteen necrosis of the femoral head and 4 hip arthritis including 1 patient with ankylosing spondylitis were found in 44 hip joints of 22 patients. MRI detected 17 femoral head necrosis and 4 hip arthritis, while SPECT/CT fusion image found out 18 femoral head necrosis and 4 hip arthritis. There was corresponding relationship in signs of hip lesions between MRI and SPECT/CT fusion imaging. Conclusion SPECT/CT fusion imaging and MRI has no markedly difference in the diagnosis of hip benign lesions, and is complementary to each other. SPECT/CT fusion image can distinguish the hip lesions from the femoral head lesions, and has a higher accuracy of diagnosing hip lesions than whole body bone scanning.
