Objective To explore the clinical efficacy of hysteroscopic IUD intrauterine surgery for incarcerated ring,and to assess the safety.Methods 586 women with the incarcerated dervice remove under hysteroscope were selected in the hospital (study group),693 women during the same period used conventional methods of taking the dervice (control group ).The status of surgery,cervical relaxation,take the dervice and effect and safety were assessed.Results The operation time,amount of vaginal bleeding and take the dervice time of the study group were (19.36 ±3.14)min,(9.42 ±2.11)mL and (8.17 ±1.90)min,which were lower than those of the control group [(30.29 ±4.08)min,(15.67 ±2.38)mL and (11.35 ±2.26)min],the differences were statistically significant (t=13.16,11.51,9.76,P<0.05).The cervical relaxation goodand take part successfully of the study group were 490 cases(83.62%)and 435 cases(74.23%),which were higher than those of the control group[374 cases (53.54%)and 362 cases(52.24%)],the differences were statistically significant (χ2 =10.28,11.35,P<0.05). Waist lower abdominal pain (0-Ⅰ grade)and vaginal bleeding number (no vaginal flow or<1 day)of the study group were 509 cases (86.86%)and 362 cases (61.77%),which of the control group were 527 cases (76.05%) and 362 (46.23%),and the differences were statistically significant (χ2 =9.94,10.23,P<0.05 ).Conclusion Hysteroscopic IUD intrauterine surgery can shorten the operation time and take the dervice time,reduce the amount of vaginal bleeding and bleeding time.It can improve the success rate of taking the dervice and has fewer negative symptoms.It has high safety and clinical advantages are obvious.

The female sheep reproductive tracts were freshly collected from a local meat processing plant and used as experimental materials. Two antibacterial peptides were isolated and characterized from female sheep reproductive tracts by two consecutive chromatographic steps. The peptide isolation procedures included acetic acid extraction, dialyzed, gel filtration chromatography on Sephadex G-50, and reverse phase high-performance liquid chromatography (RP-HPLC). Their molecular mass were 4 820.47 u and 4 012.5 u, respectively, analyzed by MALDI-TOF-MS. The partial N-terminal amino acid sequences of two peptides were determined as AYVLDEPKP and YDSGA, respectively, by Edman degradation. The antimicrobial activity was tested during each purification step by the radial diffusion plate assay and broth microdilution method. These two peptides showed good antimicrobial activities against reference strains of G~+(S. Aureus ATCC2592 and Streptococcu ATCC55121), G~-(E. Coli ATCC25922) and fungi(C. Albicans ATCC2002). The peptides did not show active hemolytic activity against rabbit blood red cells and had no significant effects on human blood coagulation system. The discovery of antibacterial peptides in sheep reproductive system reveals that antibacterial peptides may play a role in innate immunity against microorganisms in a wide range of animal species.

Objective To evaluate the influence of SP600125,a selective c-Jun N-terminal kinase (JNK) inhibitor,on the levels of serum total bile salt (TBA) and Bsep,Ntcp expression in the hepatic tissue of rats with ethinylestradiol induced intrahepatic cholestasis.Methods Rats pregnant for 15days were administered the subcutaneous injection of 17- b -estradiol propylene ( EE ) to modulate the ICP animal models,and be SP600125 to intervene.Testing the level of serum TBA and the expression of c-Jun,Bsep,Ntcp in the hepalatic tissue.Results The average gray values of c-Jun in the group of ICP models were significantly lower than the normal control group ( 101.05 ± 5.20 vs 118.99 ± 5.95,P ＜ 0.05 ).After the intervention of SP600125,comparing with the group of ICP models,the expression of Bsep,Ntcp in the group of SP600125 intervention were significantly higher,and this change in the high dose of SP600125 intervention group was more obvious ( low dose intervention group Bsep:0.452 ±0.031 vs 0.291 ±0.043,Ntcp:0.462 ± 0.015 vs 0.285 ± 0.021,P ＜ 0.05 ; high dose intervention group Bsep:0.568 ± 0.038 vs 0.291 ±0.043,Ntcp:0.605±0.020 vs 0.285 ±0.021,P ＜0.05),while the level of TBA in the serum was significantly lower.Conclusions Treatment with SP600125 can down-regulate the level of c-Jun/AP-1,and it may participate in the lower expression of Bsep、Ntcp in the ICP rats which were induced by 17-bestradiol.

Objectives To determine the changes of right ventricular hemodynamic in the early phase after lung resection and non-lung resection thoracotomy by Doppler echocardiography and to investigate the correlation with preoperative lung function.Methods 55 patients who underwent thoracotomy were divided into two groups. In group A: 15 patients underwent non-lung resection thoracotomy; in group B: 40 patients underwent lung resection. The group B were subdivided into group B1 (n=23) and group B2 (n=17), acording to the preoperative lung function results: Artery blood gas analysis were measured and right ventricular hemodynamic indices were calculated by Doppler echocardiography before and after operation,respectively.Results Right ventricular ejection fraction (RVEF) and artery oxygen pressure(PaO 2) significantly decreased (P

Magnetic nanoparticles (MNP) have been widely used as biomaterials due to their unique magnetic responsiveness and biocompatibility, which also can promote osteogenic differentiation through their inherent micro-magnetic field. The MNP composite scaffold retains its superparamagnetism, which has good physical, mechanical and biological properties with significant osteogenic effects and . Magnetic field has been proved to promote bone tissue repair by affecting cell metabolic behavior.
