Objective To compare the effects of classic intrafascial supracervical hysterectomy(CISH)and laparoscope-assisted vaginal hysterectomy(LAVH)on structure and function of the pelvic floor in women.Methods From March 2003 to December 2005,totally 35 cases of CISH and 44 cases of LAVH were performed in our hospital.The patients were followed up for 22 to 38 months after the operations.During the period,they received physical examination and life quality questionnaire,by which the degree of pelvic organ prolapse and pelvic floor function were evaluated.Results The incidence of cystocele in CISH group was significantly lower than that in LAVH group [11.4%(4/35)vs 34.1%(15/44),?2=5.481,P=0.019],whereas,no significant difference was found in the incidence of rectocele between the two groups [17.1%(6/35)vs 13.6%(6/44),?2=0.186,P=0.666].Seven(15.9%)patients in the LAVH group developed cervix prolapse,while none of the CISH group had such a situation(P=0.016).Life quality questionnaire showed that 5 patients in CISH group and 16 patients in LAVH group were satisfied with their sexual life [14.3%(5/35)vs 38.1%(16/42),?2=5.456,P=0.019].Conclusion CISH is superior to LAVH in protecting the structure and function of the pelvic floor.

Objective To exPlore the effect of mammalian target of raPamycin ( mTOR ) inhibitor eVerolimus on radiosensitiVity of human non_small cell lung cancer cell line in vitro by using eVerolimus to inhibit mTOR signaling Pathway of A549. Methods Human non_small cell lung cancer cell line A549 was subjected to radiation alone or in combination with eVerolimus treatment. The 50%inhibition concentration ( IC50 ) of eVerolimus in A549 cells was detected by methylthiazol tetrazolium ( MTT) assay in vitro. EVerolimus at the 20%inhibition concentration ( IC20 ) was used to Pretreat A549 cells for 24 h. Cells were then irradiated by X_ray with 2,4,6,8 Gy. The cell surViVal fraction was comPuted by clone formation. Cell surViVal curVe was fitted by multitarget one_hit model, and mean lethal dose ( D0 ), dose quasithreshold ( Dq ), surViVal fraction at 2 Gy ( SF2 ), and sensitization enhancement ratio (SER) were calculated. The exPression ofγ_H2AX was determined by Western blotting and then the relatiVe gray Values were analyzed. Results EVerolimus significantly imProVed the sensitiVity of A549 cells to radiation. The D0 , Dq and SF2 of eVerolimus+irradiation grouP were significantly lower than those of irradiation grouP. The SER was 1. 36. The residual amount of γ_H2AX Protein in the eVerolimus + irradiation grouP was significantly higher than that of the irradiation grouP. Conclusion EVerolimus inhibiting mTOR signaling Pathway can increase the radiosensitiVity of A549 cells.

Objective To explore the changes of Sema3A and it′s receptor Npl in temporal lobe epilepsy(TLE)rat brain and the roles in epileptogenesis mechanism.Methods TLE model was established with male healthy SD rats,in which mossy fiber sprouting(MFS)was verified using Neo-Timm staining method.Sema3A mRNA,Npl mRNA and protein was respectively analyzed by immunohistochemistry and in situ hybridization in the entorhinal cortex(EC)or dentate gyrus(DG)at different time after LiCL-PILO induced TLE.Results There were Mossy fiber sprouting(7d:0.70?0.42,15d:1.50?0.52,30 d:2.20 ?0.41,60 d:2.50?0.51)in DG inner molecular layer(IML)of TLE rat compared with those of controls (P

Crocetin, a naturally occurring carotenoid, possesses antioxidant and antiatherosclerotic properties, of which the underlying mechanism remains unclear. In the present study, we examined the effects of crocetin (0.1, 1, 10 μmol·L(-1)) on angiotensin II (Ang II, 0.1 μmol·L(-1)) induced expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) and monocyte-endothelial cell adhesion. The effects of crocetin on the activation of nuclear factor kappa B (NF-κB) and intracellular reactive oxygen species (ROS) were also observed. The results demonstrated that crocetin notably suppressed Ang II induced NF-κB activation (P<0.01) and VCAM-1 expression (P<0.05, P<0.01) in HUVECs, accompanied by a markedly reduced monocyte-endothelial cell adhesion (P<0.05, P<0.01). In addition, preincubation with crocetin resulted in a significant enhancement of cellular antioxidant capacity (P<0.05, P<0.01), while Ang II induced intracellular ROS decreased markedly (P<0.05, P<0.01). These results indicated that crocetin was capable of suppressing Ang II induced VCAM-1 expression and monocyte-endothelial cell adhesion by suppression of NF-κB activation, which might be derived from the enhancement of antioxidant capacity and subsequent reduction of intracellular ROS.

Objective To evaluate the expression and relationship of miR-100 and FZD-8, one of the major compo?nents of Wnt signaling pathway, and the correlation of their expressions with lymph node metastasis in patients with breast cancer. Methods The expression of miR-100 was determined in 50 samples of human breast cancer tissues and adjacent normal tissues by in situ hybridization. The correlation of miR-100 expression with lymph node metastasis was analyzed by Mann-Whitney U test. The expression of FZD-8 was measured in 50 samples of human breast cancer tissues and adjacent normal tissues by immunohistochemistry. The correlation of the miR-100 expression with the protein expression of FZD-8 was evaluated by Pearson rank analysis. Results The expression of miR-100 was significantly lower in human breast can?cer tissues than that in adjacent normal breast tissues [2.00 (1.00, 3.00) vs. 6.00 (3.50, 8.00)]. The miR-100 expression was lower in patients with lymph node metastasis than that in patients without lymph node metastasis [1.50 (1.00, 2.75) vs. 3.00 (2.00, 4.00)]. The expression of FZD-8 was significantly higher in human breast cancer tissues than that in adjacent normal breast tissues [8.00 (6.00, 9.00) vs. 6.00 (3.75, 9.00)]. The miR-100 expression was negatively correlated with the FZD-8 pro?tein expression in human breast cancer tissues (rs=-0.592, P<0.001). Conclusion The miR-100, as an anti-metastasis-miRNA, may involve in the metastasis of breast cancer, which may be related with the regulation of the expression of FZD-8.

A 29-year-old woman was admitted to the Department of Rheumatology,Peking Union Medical College Hospital due to intermittent rashes,fever and headache.Palpable purpura were symmetrically distributed on the extremities and trunk.Other manifestations included headache with nausea and vomiting.Elevated white blood cell (WBC) count,platelet (PLT) count,erythrocyte sedimentation rate (ESR) and C-reactive protein were the main laboratory findings.Antinuclear antibodies and antineutrophil cytoplasmic antibodies were negative.Examination of the cerebrospinal fluid (CSF) revealed high intracranial pressure,while routine cytology and biochemical tests of CSF were normal.Head MRI scan and PET-CT did not detect remarkable findings.A diagnosis of systemic vasculitis was confirmed by the biopsy of skin lesion which showed inflammatory infiltration of the muscular vessel wall.Combination therapy of corticosteroids and cyclophosphamide lead to a rapid improvement in clinical symptoms and laboratory parameters.The patient was in stable remission till 6 month follow-up.

Objective To observe the in vitro anti-Coxsackievirus B3m (CVB3m) effect of sophocarpine(SC) extracted from Sophora flavescens, a traditional Chinese herb. Methods HeLa cells were cultured and the micro-dose cytopathic effect (CPE) assays were applied to detect the toxicity of SC. CPE-inhibitory assays were used to observe the in vitro anti-CVB3m effect of SC. MTT and crystal assays were introduced to examine the anti-CVB3m effect of SC. HeLa cells were infected with CVB3m and added with SC in different concentrations 15 h later.The viability and number of survival of HeLa cells were determined by MTT and crystal violet assays, respectively. Results No toxicity was found on HeLa cells by SC with concentrations 100 ?g/mL, SC could accelerate and aggravate the CPE. SC could protect the CVB3m-infected HeLa cells with concentrations from 1.56 to 25 ?g/mL, and the viability and cell number measured by MTT and crystal violet assay in the SC-handled cells were higher and bigger than those in the virus infected ones. However, the inhibitory effect of virus was exacerbated with higher concentrations (50 and 100 ?g/mL), and the cell number and viability of the SC-handled cells were smaller and lower than those of the infected ones. Conclusion SC with a proper concentration has the in vitro anti-CVB3m effect and may protect HeLa cells from CVB3m infection.
