Objective To investigate the effects of rhubarb on the expression of glucocorticoids receptor (GR)and peripheral blood lymphocytes in burning-induced septic rats. Methods Sixty-six male healthy Sprague-Dawley(SD)rats were randomly divided into sham operated control group(n=18),sepsis model group(n=24) and rhubarb treatment group(n=24),each group was further randomly divided into 12,24 and 72 hours subgroups according to different time points. The model of scald sepsis was replicated by scald injury induced by boiling water at the rat back accounting for 30% total body surface area(Ⅲ grade of scald),and administration of endotoxin (5 mg/kg)into the peritoneal cavity 12 hours after scald injury. After the successful establishment of septic models, the rats in the rhubarb treatment group were immediately infused with 50 mg/kg rhubarb powder dissolved in 1 mL saline through a gastric tube,while the rats in sham operated control group and sepsis model group received saline by the same way as a substitute for rhubarb. The the binding capacity of GR of peripheral blood leucocyte and binding activity of GR of hepatocyte were analyzed by radiation ligands binding assay. The CD4+,CD8+as well as CD4+/CD8+ ratio in peripheral blood lymphocytes were detected by flow cytometer. Results The binding capacity of GR of peripheral blood leucocyte and binding activity of GR of hepatocyte were significantly decreased in a time-dependent manner in sepsis model group compared to those of the sham operated control group,while in the rhubarb treatment group they were increased in a time-dependent manner after interference of rhubarb, and they were higher than those in the model group at the same time points〔leukocyte GR binding capacity (locus/cell)at 12,24,72 hours :1 515.38±300.44,1 859.63±258.26,1 890.50±307.88 vs. 1 122.63±225.39, 1 008.88±150.41,724.38±91.19;hepatocyte GR binding capacity(fmol/mg):210.19±26.26,258.01±20.98, 283.38±38.21 vs. 153.11±30.07, 129.83±26.89, 94.08±14.30, all P<0.01〕. Compared with the sham operated control group,the CD4+ and CD8+ were decreased in various degrees at 12 hours and 24 hours in the septic group, at 24 hours the differences being statistically significant (P<0.01 and P<0.05). CD4+/CD8+ratios were decreased significantly at all time points,the differences were statistically significant at 24 hours and 72 hours(both P<0.01). The CD4+ T cell and CD4+/CD8+ ratio at all the time points were increased at various degrees in the rhubarb treatment group,and the differences from those in the sepsis model group at 24 hours and 72 hours were statistically significant (1.58±0.69, 1.56±0.49 vs. 1.02±0.41, 1.01±1.68, both P<0.01). Conclusion Rhubarb can modulate the binding capacity of GR of peripheral blood leucocyte and the binding activity of GR of hepatocyte,and via its influence on the number of peripheral leucocytes,the immune dysfunction in the sepsis processes is improved.

Objective: To detect the relationship between variant of rsl255372 in transcription factor 7-Like 2(TCF7L2) gene and the type 2 diabetes mellitus (T2DM) in Tianjin Han populations. Methods: Three hundred and fifty-two T2DM patients and 176 healthy controls were randomly selected to extract the genome DNA. Denaturing high performance liquid chromatography was used to detect the PCR amplified fragment. The different peaks were chosen for sequencing. The differences of different genotype frequency between the groups were analysed. The Logistic regression was used to evaluate the risk factors of T2DM. Results: The G/T genotype frequencies of rsl2255372 were 18.5% and 2.8% in T2DM group and healthy control group respectively (P < 0.05). The G/T genotype, glycosylated hemoglobin, urea nitrogen and the systolic blood pressure were the independent risk factors of T2DM, and the high density lipoprotein was the protective factor. There was no significant difference of the G/T genotype frequency in T2DM patients with different complications. Conclusion: This study indicates that G/T genotype in the TCF7L2 gene significantly contributes to T2DM susceptibility in Tianjin Han populations. The G/T genotype is one of the risk factors of the T2DM.

BACKGROUND:Articular process of joint is an important bony structure to maintain the spinal stability and normal physiological activities. Clinical study found that bilateral articular process asymmetry is also one of the causes of vertebral degeneration, but the existing research mainly focuses on the adult, and give priority to with cervical vertebra and lumbar vertebra. OBJECTIVE:To explore the morphological and developmental characteristics of thoracic facet joints and bony structures of 10 to 12-year-old children and compare with data of adults. METHODS:A total of 30 normal cases aging from 10 to 12 years were admitted into this study. No cases experienced bone destruction, deformity, fractures, or tumors, and spine surgery was not involved in. DICOM 3.0 data of multi-slice spiral CT (0.625-1.25 mm), ranging from T1 to T12, were used for three-dimensional reconstruction, measurement and statistical analysis. RESULTS AND CONCLUSION:(1) Joint width overal trends in“V”. Joint surface height from T1 to T12 increased gradual y with the increase of the operation sequence. (2) The joint thickness from T1 to T12 showed a gradual y increasing trend with the increase of the job sequence;articular process under the joint thickness was gentle. In the left and right sides of the upper and lower joints, joint surface width, height, and thickness did not show significant difference in addition to the significant difference between the individual vertebral body. Joints spacing on the side and there was no significant difference between upper and lower, articular process spacing between sides showed an increasing trend with the increase of operation sequence;upper and lower joints spacing increased with the job sequence, and showed wide“U”shape. (3) These results confirmed that the application of three-dimensional reconstruction techniques can display shape and characteristics of each vertebral body clearly and intuitively and improve measurement accuracy. Width and height of facet joints in 10-12-year-old school children were overal smal er than those of adults. The distance between upper and lower facet joints changed a little. Distance between left and right facet joints increased from T1 to T12, which complies with the growth and development of children.

Sperm-mediated gene transfer (SMGT) is one of the most methods in the transgenic animal research and the efficiency of spermatozoa binding and internalization exogenous DNA after sperm/DNA co-culture is important to a successful SMGT.In this study,the influencing factors of exogenous DNA uptake by spermatozoa were detected using DIG labeled EGFP as exogenous gene.The results demonstrated that porcine spermatozoa could spontaneously take up exogenous DNA which mainly binding occurs on the sub-acrosomal and nuclei region of the sperm head.The rate of spermatozoa binding exogenous DNA increased with the extending action of time.At 37℃ and 39℃,the rate of spermatozoa uptake exogenous DNA would not increase after 60 min incubation,and the similar result was observed on 90 min at 17℃.Binding rates and internalization rates of washed ejaculated sperm cells from the 15 boars varied between 6.57%-35.81% and 2.990%-24.66%,respectively.The binding rate and intemalization rate were mostly inhibited by seminal plasma.The binding rates were significantly increased by liposome and DMSO,respectively.Dead-spermatozoa could bind exogenous DNA,the intermalization process could not be completed.Furthermore,the highest binding rate was found in membrane broken spermatozoa as a result of freeze-thawing and this was independent of the sperm donors.

Aim To study proliferation capacity of cell and the target relationship between microRNA and Runx2 after effect of puerarin on osteoblasts MC3 T3-E1 . Methods The proliferation capacity of cell was detected by MTT after effect of puerarin on osteoblasts MC3 T3-E1 . The vitality of osteoblasts was detected by activity of alkaline phosphatase. The expression level of mRNA and protein of Runx2 were detected by real-time quantitative PCR and Western blot. The result of miRNA expression spectrum was compared with the predicted result to determine the Runx2-targeting miR-NAs. The expression levels of miRNAs possiby targeted to Runx2 were detected by real-time quantitative PCR. The RhoE 3′UTR vector and RhoE mut 3′UTR vector were constructed. miRNA-204 mimics and miRNA-204 NC were synthetised. The target genes were verified by dual luciferase report gene assay. Results After osteo-blasts treated with puerarin, proliferation capacity and activity of cells were enhanced , expression levels of mRNA and protein of Runx2 were both increased , the expression levels of miRNA-204 and miRNA-344 f-5 p were declined, the expression levels of miRNA-2861 was increased,the expression levels of miRNA-23a-5p, miRNA-770-5 p and miRNA-871-5 p showed no obvious change. According to the results of dual luciferase re-porter gene method after cell transfection of 48 h, only set of 3′UTR Runx2+mimics the miRNA-204 of fluo-rescein protein expression level decreased significantly, showing only the miRNA-204 inhibits Runx2 3′UTR report gene expression. Conclusion Puerarin pro-motes the proliferation of osteoblasts and regulates the miRNAs which possibly target to Runx2 .
