Objective To assess the contractility of levator ani muscle in postpartum female using pelvic floor three-dimensional ultrasound and to provide an effective imaging basis for the change of levator ani muscle contractility in postpartum female.Methods Totally 75 postpartum women (55 underwent spontaneous vaginal delivery and 20 underwent selective cesarean delivery) and 40 nulliparas were examined by pelvic floor three-dimensional ultrasound.The images were obtained at rest and at maximal levator ani muscle contraction.The sagittal hiatal length (L) on the two-dimensional sagittal images,the area of levator hiatus (A) and the circumference of levator hiatus (C) were measured on the three-dimensional images,and the difference value between rest and contraction were calculated to get the △L,△A,△C.Then the △L,△A,△C between different groups were compared.Results The △L,△A,△C in spontaneous vaginal delivery group and selective cesarean delivery group were smaller than those in nulliparas group (P ＜0.05),and there was no statistical difference between spontaneous vaginal delivery and selective cesarean delivery group (P ＞ 0.05).Conclusions Three-dimensional ultrasound can effectively assess the the contractility of levator ani muscle,the levator ani muscle contractility of postpartum female was poorer than nulliparas,and between spontaneous vaginal delivery and selective cesarean delivery women there is no obvious difference.

Human herpesvirus 7 (HHV-7) infection is dependent on the functions of structural glycoproteins at multiple stages of the viral life cycle. These proteins mediate the initial attachment and fusion events that occur between the viral envelope and a host cell membrane, as well as cell to cell spread of the virus. To characterize the HHV-7 glycoproteins that can mediate cell fusion, a cell-based fusion assay was used. 293T cells expressing the HHV-7 glycoproteins of interest along with a luciferase reporter gene under the control of the T7 promoter were cocultivated with SupT1 cells transfected with T7 RNA polymerase. HHV-7 glycoproteins gB, gH, gL and gO can mediate the fusion of 293T cells with SupT1 cells, and the fusion can be inhibited by anti-CD4 mAbs. Thus, the coexpression of HHV-7 gB, gO, gH and gL is sufficient and necessary for HHV-7 induced membrane fusion, and one of these glycoproteins or protein complex formed by these glycoproteins might be the ligand(s) of CD4 molecule.

Objective To investigate the applications of antibacterial agents to outpatients in primary hos -pitals in Hefei City of Anhui Province,and to provide reference for rational use of antibacterial agents.Methods In 2011, fourty-five primary hospitals in Hefei City were selected randomly ,including urban community health service centers (Group A) and township hospitals(Group B),and thirty or fourty outpatient prescriptions were analyzed monthly . Results In Group A, the percentage and intensity of antimicrobial usage , the proportion of the combination and injectable formulation were ( 45.36 ±20.02 )%, ( 89.73 ±25.50 ) DDDs · ( 100 cases ) -1 · d-1 , 13.34%, 23.16%,respectively,and the data in Group B were (61.36 ±17.18)%,(108.46 ±32.27)DDDs· (100 cases) -1 · d-1,29.13%,46.39%,respectively,which the former were significantly lower than the latter.Conclusion In primary hospitals,the applications of antibacterial agents to outpatiants are not rataional ,including high percentages of usage and unreasonable selection of species ,and more supervision and training need to be given to the medical staff , especially in township hospitals .

Objective To analyze the affection and clinical significance of CD26/DPP4 on CD4+T cells and its cytokines in patients withCrytococcalMeningitis.Methods Peripheral blood was collected from 36 patients diagnosed withCrytococcal Meningitis in Changhai Hospital and Changzheng Hospital,Shanghai from August,2011 to December,2015,meanwhile 36 health controls’was also acquired.Peripheral blood mononuclear cell (PBMC)was separated by density gradient centrifuga-tion,CD26+CD4+T and CD26-CD4+T cell groups were classified by Flow Cytometry,the expression level of cytokines was tested by reverse transcriptase-polymerase chain reaction (RT-PCR).The correlation between DPP4 activity,CD26+CD4+T (%)and APACHE II score,IL-17,TNF-α,IL-4,IFN-γwas measured by Pearson coefficient.Results CD26+CD4+T(%)between experimental and control groups was 13.35±3.83 vs 8.39±2.14 (t=6.78,P<0.000 1).DPP4 activity was 50.89±17.21 mU/ml vs 73.83±20.24 mU/ml (t=5.18,P<0.000 1),with statistically significant differences.In ex-perimental groups,CD26+CD4+T (%)was positively related with APACHE II score,IL-17,TNF-α(r=0.431,0.564, 0.688,P=0.003 8,0.001,0.004 6).DPP4 activity was negatively interrelated with APACHE II score,IL-17,TNF-α,IFN-γ(r=-0.544,-0.489,-0.678,-0.734;P<0.001).Conclusion CD26/DPP4 may be involved in the pathogenesis of Crytococcal Meningitis through regulation of Th subgroups,and it was the potential therapeutic target and the predicted marker of the disease.

Naturally occurring mutations in surface proteins of Hepatitis B virus(HBV)usually result in altered hepatitis B surface antigen(HBsAg)secretion efficiency.In the present study,we reported two conserved residues,M75 and M103 with respect to HBsAg,mutations of which not only attenuated HBsAg secretion(M75 only),but also suppressed HBV genome replication without compromising the overlapping p-gene product.We also found M75 and M103 can initiate truncated surface protein(TSPs)synthesis upon over-expression of full-length surface proteins,which may possibly contribute to HBV genome replication.However,attempts to rescue replicationdefective HBV mutant by co-expression of TSPs initiated from M75 or M103 were unsuccessful,which indicated surface proteins rather than the putative TSPs were involved in regulation of HBV genome replication.

Objective To explore the effect of Bailing capsule on epithelial-mesenchymal transition( EMT) in rats with adenine-in-duced tubulointerstitial fibrosis. Methods Tubulointerstitial fibrosis animal models were established and SD rats were divided into mo-del group ( n = 30), treatment group ( n = 30) and control group( n = 30), randomly. Experimental rats were harvested at 7 w, 12 w,17 w after onset of experiment and functional evaluations were performed. Histology, immunohistology were examined to investigateboth histolopathology changes and the expression of bone morphogenic protein-7 (BMP-7), transforming growth factor-β1 (TGF-β1 )and a-smooth muscle actin (α-SMA) in kidneys at three time points mentioned above, respectively. Results Compared with controlgroup, 24 h urinary protein in model group lost increasingly and significantly difference appeared at three time points relative to controlgroup ( P ＜ 0.01 ). Urinary NAG in model group was markedly higher than that in control group from 7 w after onset (P ＜ 0.01 ) andwas increasingly raised at 12 w and 17 w (P＜0.01). The value of blood BUN and Cr in model group increased at 7 w (P＞0.05) rel-ative to control group. There was significant difference at 12 w and 17.w (P ＜ 0.01 ). Histologically, kidneys in model group, at 7 w,exhibited tubular casts and gently tubular dilation, granuloma in cortex, mononuclear cells infiltration in tubulointerstitial areas, andmild interstitial fibrosis. At 12 w, the degree of tubular injury and tubulointerstitial fibrosis gradually aggravated. Up to 17 w, diffusetubular dilation or atrophy was observed and focal tubules disappear. Diffuse interstitial fibrosis was exhibited. In normal kidneys, im-munohistochemistry suggested that the light expression of BMP-7 was detected in proximal renal tubular epithelial cells and marked ex-pression was identified in distal tubule, collecting duct, and renal tubular epithelial in junction area between cortex and medulla. How-ever, the expression of BMP-7 in kidneys of model group significantly decreased with increasing tubulointerstitial fibrosis and was nega-tive correlation with the expression of TGF-β1(r = -0. 981 P＜0.01) and α-SMA (r= -0.975 P＜0.01). Bailing capsule ad-ministration protected the expression of BMP-7 and reduced TGF-β1 and α-SMA expression before 12 w(P＜ 0.01 ). Conclusions Ourstudy shows an anti-fibrotic reno-protective function of Bailing capsule in rats with tubulointerstitial fibrosis via prevention of epithelial-mesenchymal transition at early stage. However, the beneficial effect lost with increasing tubulointerstitial fibrosis.
