Objective To investigate the significance of macrophage migration inhibitory factor(MIF) in ovarian endometriosis (OEms).Methods MIF of ectopic endometriumeutopic endometrium in OEms and endometrium in non-endometriosis (30 cases in every group ) was detected by Elivision TM plus immunohistochemical.Quantitative images analytical system was performed with computer to analyze the mean absorbance(A) of MIF.Results The A of MIF in ectopic and eutopic endometrium of OEms and the normal control was respectively ( 0.180 ± 0.013 ),( 0.158 ± 0.022 ) and ( 0.143 ± 0.029 ),there was statistical significance between groups ( F =47.676,P ＜ 0.001 ).The expression of MIF in proliferative phase of eutopic endometrium of OEms was(0.157 ±0.018),extremely stronger than that in the same phase of the normal control (0.146 ± 0.029 ) ( t =2.656,P =0.009 ) ; and MIF in secretory phase of eutopic endometrium of OEms was (0.160±0.028),obviously higher than that in the same phase of the normal control(0.137 ±0.030) (t =3.059,P =0.003).Conclusion The MIF may play a significant role in the pathogenesis and development of ovarian endometriosis.

Objective To investigate the significance of hypoxia inducible factor-1(HIF-1) expression in ovarian endometriosis (Oems). Methods Elivision Tm plus Immunohistochemical and Stereology methods were used to detect HIF-1 expression in 30 cases of ectopic endometrium, 30 cases of eutopic endometrium in ovarian endometriosis and 30 cases of endometrium in ovarian teratoma as the normal control. Quantitative images analysis was performed with the aid of computer to collect and analyze the mean optical density (MOD) of HIF-1 expression. Results The MOD values of HIF-1 in ectopic and eutopic endometrium of Oems and the normal control were 0. 077 ± 0. 014, 0. 070 ± 0. 013 and 0. 061 ± 0. 007 respectively, which showed significantly differences between each other groups(F = 37. 738, P ＜ 0. 01 ＝. HIF-1 expression in proliferative phase (0.076 ±0.007) of eutopic endometrium of Oems was significantly higher than that in secretary phase (0. 059 ±0. 014) (t = 6. 918 ,P ＜0. 01 ＝; which was also significantly higher than that of the normal control in the same phase (0.060±0.007) (t=-12.724,P ＜0.01 ＝.Conclusion HIF-1 may play an important role in the pathogenesis and development of Oems.

Objective To investigate the effects of different concentrations of sevoflurane on adhesion and expression of CD 44 in human breast cancer cell line MCF‐7 .Methods The cells were randomly divided into 4 groups :control group and 3 sevoflurane groups exposed to 1 .7% ,3 .4% and 5 .1% sevollurane for 2 ,4 and 6 h respectively .Cell adhesion rate was detected by adhesion test and the expression of CD44 mRNA and protein was determined by qRT‐PCR .Results in Treat 1 ,2 ,3 ,the adhesion rate at 2 ,4 ,6 h were lower than that before treat ,mRNA expression of CD44 reduced (P<0 .05);the adhesion rate of Treat 2 and Treat 3 at 4 and 6 h were lower than that of 2 h ,and the mRNA expression of CD44 reduced (P<0 .05);the adhesion rate of Treat 2 and Treat 3 at 6 h were lower than that of 4 h ,and the mRNA expression of CD44 reduced (P<0 .05);compared with Control group ,the adhesion rate of Treat 1 ,2 and 3 at 2 ,4 ,6 h were all lower ,mRNA expression of CD44 reduced (P<0 .05);the differences between each group were statisyicaly significant(P<0 .05) .Conclusion Sevoflurane can inhibit cell adhesion in a concentration and duration of exposure dependent manner ,and its mechanism could be related with the down regulation of CD44 expression .

Objective To explore the effect of spa with free position on parturition of primipara.Methods One hundred and thirty-eight primiparas were equally randomized into control group and observation group. The control group conducted Doula delivery,which means a delivery at recumbent or semi-recumbent position when mouth of the uterus opened by 3 cm and the primiparas in the observation group took free position with spa based on Doula delivery. The two groups were compared in terms of the durations of each labor and total labor, postpartum bleeding 2 h after delivery and neonatal Apgar score,delivery way,pains,anxiety and feeling of control at delivery.Results The postpartum bleeding in the observation group was significantly lower than that in the control group(P<0.05). The durations of first labor, second labor and total labor in the observation group were all significantly shorter than those of the control. The degrees of pain and anxiety were lower than those of the control group,while the control sense at delivery was better than that of the control group(P<0.05,for all). There were no differences in the rate of spontaneous delivery,the rate of uterine-incision delivery,the rate of episiotomy and scores on 1 min Apgar scales(P>0.05).Conclusion Aided delivery by spa with free position can reduce labor pain and anxiety levels,improve the birth control and comfort and ultimately enhance the sense of delivery control and comfort.

Objective To study the effect of the PDCA management on safety management of venous transfusion by indwelling needles?.Method The measures included standardizing nurses manipulation,improving the management system related to venous transfusion,and regulating details management process for tube fixing and dressing and tube maintenance.Results The rates of unstandardized maintenance and obstruction of tubes after the enforcement of details management were significantly lower than those before its enforcement(P<0?05).Conclusions PDCA management is effective for standardizing nursing implementation and ensuring the safety of venous transfusion by indwelling needle?

This study was aimed to summarize main-bone structure of cantharidin-based small molecules and facts about three typical candidates including its origin, physical-chemical properties and general synthetic approaches. Basic chemical and pharmacological information as well as development of anti-cancer activities, which were related to cantharidin, norcantharidin and their analogues were reviewed, especially the relationship between the structures and their inhibitory activity and selectivity of serine-threonine protein phosphatases PP1, PP2A and PP2B in cancer treatment. The designs and developments of new biological cantharidin-based small molecules were also reviewed.

Objective To observe the effect and influence on plasma angiotensin Ⅱ and oxygen radicals in the treatment of children with viral myocarditis by phosphate sodium and captopril,provide reference for clinical treat-ment.Methods 80 children with viral myocarditis met the admissions criteria were randomly divided into the obser-vation group(40 cases)and the control group (40 cases),both group were received conventional therapy,which included rest,vitamin C pin,antiviral and antimicrobial agents,nutritional medicine myocardial metabolism of drugs. The control group was given captopril 0.5mg/kg,bid,the observation group was given phosphate sodium and capto-pril,phosphate sodium 0.5 -1g/d,qd,both groups had been treated for 4 weeks for a course.Plasma angiotensin Ⅱwere detected by radioimmunoassay.The EF,FS,VA /TE were detected by echocardiography instrument.The blood were collected for detecing MDA and SOD.The clinical efficacy and electrocardiogram efficacy were evaluated. Results The clinical efficacy and electrocardiogram efficacy of observation group were 95%,90%,the control group were 70%,70%,and the difference was statistically significant(χ2 =9.367,8.571,both P <0.05).The EF,FS,SOD of the observation group and the control group after treatment was significantly higher than those of before treatment (t =11.689,8.447,9.524 and 7.714,7.985,6.166,all P <0.01).The plasma angiotensin Ⅱ,VA /TE,MDA were significantly lower than those of before treatment(t =17.572,5.772,9.744 and 9.228,3.553,3.855,all P <0.05). The SOD of the observation group after treatment was significantly higher than that of the control group(t =3.932, P <0.05),VA /TE,MDA were significantly lower than that of the control group(t =3.446,3.633,10.315,all P <0.05).Conclusion The method containing phosphate sodium and captopril can collaboratively improve heart func-tion,which may be relate to the decrease in plasma angiotensin Ⅱ and scavenging oxygen free radicals.The method can significantly improve the clinical efficacy and ECG efficacy of conventional therapies,is the better treatment for promoting in the treatment of children with viral myocarditis.
