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.

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 remove murine embryonic stem cells(mESC)from the differentiating cell culture and purify the differentiated cells by Magnetic Activated Cell Sorting(MACS).Methods:Neural differentiation of mESC was induced by a 5-stage method.The specific cell surface marker,SSEA-1,was used to identify ES cells in the differentiating cells.The optimal dilutions of mouse anti mouse SSEA-1 IgM primary antibody and FITC conjugated goat anti mouse secondary antibody were determined before the flow cytometry test.The incubation time and incubation temperature of primary antibody were all optimized to make the cytometry test accurate.After the optimization,stage 4 cells were dissociated into single cell suspension,incubated with antibody of SSEA-1 and microbeads conjugated goat anti mouse IgM,and then sorted through the magnetic field.The rate of SSEA-1 positive cells in pre-and post-separation groups was assessed by flow cytometry,and the viability of cells was evaluated by trypan blue staining counting under light microscopy.Results:The proportion of SSEA-1 positive cells in the separated cells can be reduced from(7.19?1.36)% to(1.34?0.80)%.The survival rate of sorted cells was more than 92%,similar to that of pre-separation cells.Conclusions:The MACS system we used can effectively remove mESC from the differentiated cells.The sorted cells will be well provided for the subsequent studies about transplantation therapy.

Objective To investigate the changes of thyroid hormone in peritoneal dialysis patients and analyse its impact factors, as well as the therapeutic effects of small dose of thyroxine.Methods 150 uremic patients in Hunan Provincial People’s Hospital from December 2013 to December 2014 were selected, 70 cases of uremia non-dialysis patients were divided into group A, while 80 uremia peritoneal dialysis for more than half a year were divided into group B.70 cases healthy examinees during the same period in our hospital were selected as control group ( group C ) . The total triiodothyronine (T3), total thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), hemoglobin (Hb), serum albumin (ALB), total cholesterol (TC), triglyceride (TG), serum creatinine (SCr), C reactive protein (CRP) and left ventricular ejection fraction ( LVEF) , subjective global assessment of nutritional act ( SGA) and other indicators were detected in three groups.Patients in group B were divided into two sub-groups according to thyroid hormone levels: B1 group had normal thyroid level while B2 abnormal.And the administration of small dose of thyroid hormone was given to patients in group B2, and the effect of the administration was evaluated by the above indexes.Results The FT3 in group A and B were significantly lower than that in group C (P<0.01).There were significant differences of levels of ALB, CRP, SGA between group B1 and group B2, and the FT3 level in group B was significant correlated with SGA, ALB, LVEF(r=0.815,P<0.001;r=0.780,P<0.001;r=0.953,P<0.001).After treated with small dose of thyroid hormone, FT3 and LVEF were improved while FT4, TSH, ALB, SGA, CRP were not improved in group B2.Conclusion The thyroid hormone level in patients with continuous ambulatory peritoneal dialysis decreases which is dominated with FT3.The decreased thyroid level is significantly correlated with nutrition ( ALB, SGA) and left ventricular function.The administration of small dose of thyroid hormone can improve the left ventricular systolic function.

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.
