ABSTRACT
Objective To investigate the effect of aspirin on the endometrium of patients with severe intrauterine adhesions after electrical resection.Methods 130 patients with severe intrauterine adhesions after electrical resection from August 2013 to August 2015 in our hospital were selected and randomly divided into the observation group and the control group ( 65 cases in each group ); The control group were given progestogen sequential therapy, while the observation group were given aspirin for treatment on basis of the control group; All the two groups were treated for three menstrual cycles; Before and after treatment indexes including uterine endometrial thickness, ovulation of the uterine artery blood flow index artery pulsatility index in ultrasound (PI), resistance index (RI), endometrial blood flow parameters[vascular index (VI), flow index (FI) and vascular blood flow index (VFI)] were recorded and compared, as well as menstruation and uterine cavity shape 3 menstrual cycles after treatment;All the two groups were followed up for one year, and one year pregnancy rates in the two groups were recorded.Results After treatment, the total efficiency in the observation group was 92.3% significantly higher than 69.2% in the control group ( P <0.05 ) .After treatment, in the two groups endometrial thickness, PI, RI, VI, FI and VFI were significantly improved compared with before treatment (P<0.05), but the observation group improved more obviously (P<0.05).Within one years in the observation group the pregnancy rate was 57.1%higher than that in the control group 26.5%(P<0.05) .Conlcusions Application of aspirin can significantly improve the endometrial thickness on the basis of estrogen and progesterone sequential therapy , increase the endometrial blood flow and improve the pregnancy rate, which mechanism may be related to promoting endometrial repair and improving blood perfusion of the uterus.
ABSTRACT
Objective To evaluate the value of echocardiography in the evaluation of congestive heart failure (PHC) in peripartum cardiomyopathy patients.Methods 64 patients with congestive heart failure were randomly divided into two groups.The control group were treated with routine therapy.The study group were treated with levocarnitine in combination with routine therapy.Echocardiography was performed before and after treatment, and the changes of each index were compared.Results There was no significant difference in left ventricular end diastolic diameter, left ventricular ejection fraction and cardiac output between the two groups before treatment.After treatment, the left ventricular end diastolic diameter, left ventricular ejection fraction and cardiac output in study group after treatment were higher than those in control group(P<0.05).There was no significant difference in left ventricular short axis shortening, left ventricular end-systolic diameter and stroke volume between the two groups before treatment, but the left ventricular short axis shortening and stroke volume in study group after treatment were higher than those in control group (P<0.05), the left ventricular end-systolic diameter was lower ethan that in control group ( P<0.05 ) .The treatment effect of the study group was significantly higher than that in control group (P<0.05).The adverse reactions was significantly lower than that in the control group (P<0.05).Conclusion L-carnitine is effective in the treatment of heart failure in peripartum cardiomyopathy patients.It can be used to evaluate the therapeutic effect of cardiac ultrasound in order to provide guidance for clinical treatment.
ABSTRACT
Objective To enhance oral tablets ward pharmacy inventory efficiency and improve the comprehensive quality of the pharmacist by QCC activities .Method Main factors to extend the ward pharmacy tablet counting time were analyzed through collecting the previous ward pharmacy tablet count time and account matching rate .According to the main problems , the strategies were found out to be implemented ,identify and evaluate the implementation result .Result In view of the oral medicine ward pharmacy inventory of the reasons for the low efficiency ,following measures should be taken :reducing oral drug dispensing station varieties ,finishing cargo ,strengthening personnel training ,changing inventory counting method and optimi-zation of inventory materials and re-enacted drugs location code and so on .Ward pharmacy tablet counting time reduce from 6 .5 hours to 3 hours (reducing by 53 .85% ) .Conclusion The QCC activities could significantly improve the oral medicine ward pharmacy inventory efficiency and comprehensive quality of pharmacists .
ABSTRACT
Retinitis pigmentosa (RP) is a group of clinically and genetically heterogeneous retinal degenerative hereditary diseases that cause severe vision impairment and often blindness.They are characterized by dysfunction and loss of retinal pigment epithelial (RPE) cells and photoreceptor cells.Sodium iodate (NaIO3) is an antimetabolite known to selectively damage RPE.The RP induced by NaIO3 resemble patchy loss of RPE in human RP,and has been frequently used to establish a RP model.The RP models induced by NaIO3 can be established in a variety of experimental animals.Among those models,the RP model induced by one injection of NaIO3 is most commonly used.The NaIO3-induced RP animal models can be manipulated in terms of onset age and disease progression.Moreover,RPE cells in some animals have a self-regenerative potential under specific conditions.Therefore,this model is relevant in the study of RP pathogenesis,drug or stem/progenitor cell therapy and regenerative medicine.There have been many reports on researches and application of NaIO3-induced RP models,we summarized recent progress in this model.
ABSTRACT
Mytilin-derived-peptide-1 (MDP-1) and mytilin-derived-peptide-2 (MDP-2) are two truncated decapeptides with reversed sequence synthesized corresponding to the residues 20-29 of mytilin-1 (GenBank Accession No. FJ973154) from M. coruscus. The objective of this study is to characterize the structural basis of these two peptides for their antimicrobial activities and functional differences, and to investigate the inhibitory mechanism of MDPs on Escherichia coli and Sarcina lutea. The structures of MDP-1 and MDP-2 in solution were determined by 1H 2D NMR methods; the antibactericidal effects of MDPs on E. coli and S. lutea were observed by transmitted electron microscopy (TEM). Both MDP-1 and MDP-2 have a well-defined loop structure stabilized by two additional disulfide bridges, which resemble the-hairpin structure of mytilin-1 model. The surface profile of MDPs' structures was characterized by protruding charged residues surrounded by hydrophobic residues. TEM analysis showed that MDPs destroyed cytoplasmic membrane and cell wall of bacteria and the interface between the cell wall and membrane was blurred. Furthermore, some holes were observed in treated bacteria, which resulted in cell death. Structural comparison between MDP-1 and MDP-2 shows that the distribution of positively charged amino acids on the loop of MDPs is topologically different significantly, which might be the reason why MDP-2 has higher activity than MDP-1. Furthermore, TEM results suggested that the bactericidal mechanisms of MDPs against E. coli and S. lutea were similar. Both MDP-1 and MDP-2 could attach to the negatively charged bacterial wall by positively charged amino acid residues and destroy the bacteria membrane in a pore-forming manner, thus cause the contents of the cells to release and eventually cell death.
