Objective To investigate the clinical curative effect of oral and acupoint application of traditional chinese medicine combined with Azithromycin for the children with Mycoplasma Pneumonia. Methods A total of 160 children with mycoplasma pneumonia were divided into two groups according to digital random table method, with 80 cases in each group. The patients of the two groups were given conventional treatment to relieve cough and reduce phlegm; On the basic treatment of conventional treatment, the control group were treated with azithromycin, wile the treatment group were treated with oral traditional chinese medicine Tinghuang runfei decotion and acupointion application of Tinglizi, Baijiezi, Shengnanxing, Dahuang, and Bingpian. The treatment of both groups last 3 weeks. The time of defervescence, the disappearance time of cough and pulmonaryrales of the two groups were compared, and the serum levels of inter leukin 8 (IL-8), tumor necrosis factor-a (TNF-a), thrombin regulatory proteins (TM), D-dimer were compared before and after treatment. The total effect rate and the incidence of adverse events were compared.Results The defervesce time (3.79 ± 1.68 dvs. 4.88 ± 1.61 d,t=3.846), disappearance time of cough (8.21 ± 2.42 dvs. 10.35 ± 2.60 d,t=5.389) and disappearance time of pulmonary rales (6.21 ± 1.89 dvs. 7.78 ± 2.08 d,t=4.997) in the treatment group were significantly less than those in the control group (P<0.01). The levels of IL-8 (9.98 ± 4.26 ng/Lvs.14.18 ± 4.82 ng/L, t=5.840), TNF-a (20.78 ± 5.93ng/Lvs. 26.07 ± 6.42 ng/L,t=5.414), TM (9.63 ±  2.88μg/Lvs. 13.08 ± 3.37μg/L,t=6.961), D-dimer levels (0.09 ± 0.04 ng/Lvs. 0.15 ± 0.06 ng/L,t=7.442) the treatment group were significantly better than those in the control group (P<0.01). The total effect rate in the treatment gruop was significantly higher than that of the control group (97.5%vs. 88.8%;χ2=4.783,P=0.029), but there was no significant difference in the incidence of adverse events between the two groups (16.3%vs. 10.0%;χ2=1.370,P=0.272).Conclusions Oral and acupointion of traditional chinese medicine Tinghuang runfei decotion combined with azithromycin could relieve the symptoms, improve the clincal effect and show its safety for the children with mycoplasma pneumonia.

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.

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.

ObjectiveTo study the effects of small-dose glucocorticoid (GC) on glucocorticoid receptor (GR) and cellular immune function in critical patients.MethodsForty ICU critical patients admitted in Shanghai Changzheng Hospital from March 2007 to March 2009 were enrolled in the study and were divided into GC group and non-GC group according to the use or absence of GC.Blood samples were collected at days 1,7 and 10 after GC treatment to detect GR binding affinity of mononuclear leukocytes (MNLs) and polymorphonuclear leukocytes (PMLs) in the peripheral blood and the CD4/CD8 ratio in the T lymphocytes.The method of GC use was that the hydrocortisone was given intravenously at a dose of 100 mg every eight hours.ResultsGR binding capacity of MNLs at day 1 and 7 showed no statistical difference between the GC and non-GC groups.GR binding capacity of MNLs in the GC group was lower at day 1 and was much lower at day 7 (P ＜ 0.05 ).However,in the non-GC group,it was lower at day 1,but showed significant improvement at day 7 ( P ＜ 0.05 ).The change of GR binding capacity of PMLs was similar to that of MNLs.There was no significant difference of CD4/CD8 ratio between the GC and non-GC group at day 1.The ratio of CD4/CD8 in the non-GC group was significantly higher than that in the GC group at day 10 (P ＜0.05).CD4/CD8 ratio in the GC group showed a slight reduction at day 10,with no significant difference from that at day 1.While,the non-GC group showed a significant increase of CD4/CD8 ratio at day 10 as compared with that at day 1 (P ＜ 0.05 ).ConclusionLow-dose GC plays some role in the negative feedback regulation of GR binding capacity of peripheral blood leukocytes and in the inhibition of cellular immune function.

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.

Objective To investigate the expression and role of β-catenin in small-for-size liver grafts during early stage of liver regeneration after liver transplantation in rats.Method The livers of male Sprague-Dawley rats were reduced to 30％ or 50％ of their original sizes and transplanted.The experiment was divided into 3 groups:small-for-size graft group (SSG),half-size graft group (HSG) and sham-operated group.Liver samples were harvested at various time points after transplantation (n =6 per time point) for Western blotting and immunohistochemistry.Six rats in each group were sacrificed at 3rd day after liver transplantation for estimating liver regeneration rate.Result Liver regeneration rate in SSG group was lower than that in HSG group.The expression of β-catenin was down-regulated in liver graft of both groups after being stored in cold Ringer solution for 2 h.The expression of β-catenin was significant up-regulated in HSG group from 5 min to 12 h after operation,while the down-regulated expression of β-catenin was persisted in SSG group at 5 min after operation,and mildly increased expression of β-catenin occurred at 2 h and 6 h,which was significantly lower than that in HSG group at the corresponding time points.The expression of active-β-catenin was low in each group before transplantation.Significant expression of active-β-catenin was found at 5 min in HSG group and persisted until 12 h after operation,mildly increased expression of active-β-catenin in SSG group was only found at 2 h,which was lower than that in HSG group at the same time points.Immunohistochemical staining revealed that β-catenin was mainly expressed on the hepatocyte membrane and in cytoplasm in the sham-operative group,many hepatocytes exhibited nuclear localization of β-catenin in HSG group from 5 min to 24 h,while only some hepatocytes exhibited nuclear localization of β-catenin in SSG group.The expression of Cyclin D1 in SSG group was significantly lower than that in HSG group,which was similar to the expression of C-Myc.Conclusion Attenuated activation of Wnt/β-catenin signaling and down-regulated expression of target genes during early regeneration of small-for-size liver grafts may be involved in the inhibition of liver regeneration of small for size liver grafts.

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 .

Objective To explore the morphological characteristics and change rule of thoracic joint angles in children aged from 10 to 12 years through thinner CT scanning and 3D reconstruction,and to provide theoretical basis for early diagnosis,treatment and prevention.Methods Totally 30 normal cases aged from 10 to 12 years were admitted into this study.There was no bone destruction,deformity,fractures,tumors and spine surgery involved.DICOM 3.0 data of multi-slice spiral CT (0.625 ～ 1.25 mm),ranging from T1 to T12,were used for 3D reconstruction,measurement and statistical analysis.Results The difference between left and right sagittal section angle of zygopophysis was less than 10°.There was no significant differences between T1,T11,and T12for sagittal section angle of upper zygopophysis (P ＞ 0.05).So was it between T3,T4,T9,T10 and T11 for sagittal section angle of lower zygopophysis (P ＞ 0.05).While there were significant differences between others(P ＜ 0.05).The was no significant difference between left and right coronal plane angle of zygopophysis (P ＞ 0.05).Coronal plane angle of lower and upper zygopophysis tended to be ‘ spike-like’,and the maximum points were at T7 to T9.For horizontal plane angle,left and right upper zygopophysis made significant differences between T2,T4,T8,T10 and T12 only,so did T7 lower zygopophysis (P ＜ 0.05).Horizontal angle of upper zygopophysis tended to be stable in the upper thoracic both in the left and right side,while a decreasing trend was shown in lower thoracic.Horizontal angle of lower zygopophysis showed a decreasing trend generally except individual vertebrae.Both upper and lower zygopophysis showed negative angle at T11 and T12 levels.Conclusion Thoracic joint angles(coronal,sagittal and horizontal angle) in children aged from 10 to 12 years can directly reflect the developmental regularity with growth,and it verified the tendency that horizontal facet joints of the cervical spine gradually changes to coronal facet joints thoracic spine and then changes to sagittal facet joints of lumbar spine.And the left and right side facet joints are basically symmetrical with the angle difference less than 10°.

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.
