Objective To study the effect of evidence-based nursing care on medication compliance and rehabilitation effect of elderly patients with angina pectoris. Methods 89 cases of elderly people with angina pectoris were divided into the control group(43 cases )and the observation group(46 cases).The control group was treated with cardiology common nursing, the observation group received evidence-based nursing care of psychological nursing, life nursing and medication compliance. The medication compliance in each period of a year and rehabilitation effect after one year were analyzed and compared between the two groups. Results The medication compliance rate of the observation group was higher than the control group after 1, 2, 4weeks, 3, 6 months and 1 year, the total effective rate of rehabilitation was 91.3% in the observation group, also higher than the control group (62.8%)after 1 year. Conclusions Evidence-based nursing care can improve the medication compliance and the effect of rehabilitation of elderly patients with angina psctoris.

Background Idiopathic macular epiretinal membrane (IMEM) shows a high incidence and affects visual function of patients.The primary management of IMEM is vitrectomy,but the study on prediction of visual acuity after operation by optical coherence tomography (OCT) is seldom.Objective This study was to evaluate the predicting ability of OCT for preoperative visual outcome for IMEM patients who received vitrectomy.Methods The clinical data of IMEM patients with vitrectomy from March 2009 to May 2013 were retrospectively analyzed in People's Hospital Peking University.Forty-nine eyes of 48 cases were divided into continuous group (19 eyes of 18 cases) and discontinuous group (31 eyes of 31 cases) based on whether the extraretinal layers were intact on OCT,including retinal pigment epithelium (RPE),inner and outer segment of photoreceptors (IS/OS) and external limiting membrane (ELM).Central foveal thickness (CFT) by high-resolution spectral-domain OCT and best corrected visual acuity (BCVA) (LogMAR) before surgery and 12 weeks after surgery were recorded and compared between the two groups,and the correlations of shift of CFT with the shift of LogMAR vision was analyzed by unitary linear regression to evaluate the value of OCT in predicting postoperative vision.Writen informed consent was obtained from each patient prior to any medical operation.Written informed consent was obtained from each patient before surgery.Results In 12 weeks after operation,reflective strips of RPE layer,IS/OS and ELM layer were intact in 18 eyes of the continuous group after vitrectomy.The number of eyes with discontinuous strip in RPE layer decreased to 1 eye after operation from 6 eyes before operation,and the number of eyes with IS/OS reflective strip discontinue decreased to 19 eyes after operation from 29 eyes before operation,and that with ELM layer discontinue decreased to 15 eyes after operation from before operation in the discontinuous group.The improvement of LogMAR BCVA was increased with the decline of CFT values with a negative correlation between them (R2 =0.298,B =0.001,P =0.000),and postoperative LogMAR visual acuity improved 1 line whenever CFT reduced by 100 μm.LogMAR BCVA was 0.4±0.19 before surgery and 0.36±0.21after surgery in the continuous group,showing a insignificant difference between them (t =0.876,P=0.393).In the discontinuous group,the postoperative IogMAR BCVA was significantly higher after operation (0.46±0.26) than 0.82 ±0.41 after operation (t =6.206,P =0.000).The increase value of LogMAR after vitrectomy was 0.3 in the discontinuous group,which was superior to 0.0 of the continuous group.Conclusions The continuity of extraretinal layers and CFT by OCT are closely associated with the improvement of vision after vitrectomy in the eyes with IMEM.Postoperative vision is better in IMEM eye with continuous retinal reflective strips before operation,and majority of IMEM eyes can improve vision after operation.Preoperative OCT seems to be an important diagnostic tool for the selection of patients who benefit or not from surgery to certain extent.

[Summary] Epithelial ovarian carcinoma has the highest fatality rate among gynecologic malignant tumors.Lacking of effective early diagnosis and screening method are the main reasons for its poor prognosis.There is a close relationship between the heterogeneity of epithelial ovarian carcinoma and the diversity of cancerous origins.According to the traditional theory, epithelial ovarian carcinoma derives from germinal epithelium at ovarian surface.The “secondary Mullerian system” theory has challenged above view.This“dualism” theory completely subverts the traditional one.However, both of the theories have their limitations.In recent years, the multiple origins theory of epithelial ovarian carcinoma has gradually become a hot point of discussion.

Objective To investigate the protein and mRNA expression of NF-κB and zinc finger protein A20 in the keloid and normal skin and to explore its underlying molecular biological mechanism.Methods The protein and mRNA expression of NF-κB p65 and zinc finger protein A20 in keloid and normal skin was detected by immunohistochemistry and real time quantitative reverse transcription-polymerase chain reaction (RT-PCR).Results The protein and mRNA expression of NF-κB p65 in keloid tissues was higher than those in normal skin tissues (P＜0.05).The protein and mRNA expression of zinc finger protein A20 in keloid tissues was lower than those in normal skin tissues (P＜0.05).Conclusions NF-κB signal pathways and zinc finger protein A20 could play a role in keloid pathogenesis.

Objective To observe the therapeutic effect of phloroglucinol combined with diazepam in prolonged or protracted active phase of first stage of labor,and the outcome of perinatal phase.Methods Two hundred vaginal delivery primipara with prolonged or protracted active phase after dilatation of cervix 2-3 cm were selected.The patients were divided into 2 groups by random digits table method with 100 cases each,the patients in observation group were given phloroglucinol 80 mg and diazepam 10 mg,and the patients in control group were given diazepam 10 mg.The cervical dilatation,the degree soft hardness and edema of cervix,time of active phase,time of second stage of labor,mode of delivery,vaginal bleeding in 2 h postpartum and outcome of perinatal phase in the 2 groups were observed.Results In observation group,the cervical dilatation rate was (2.31 ± 0.27) cm/h,the time of active phase was (187.27 ± 33.22) min.In control group,the cervical dilatation rate was (1.82 ±0.48) cm/h,the time of active phase was (251.32 ± 45.33) min,there were statistical differences between 2 groups (P ＜ 0.05).The rate of uterineincision delivery in observation group was significantly lower than that in control group [18.0％(18/100) vs.32.0％ (32/100)],there was statistical difference (P ＜ 0.05).There were no statistical differences in time of second stage of labor,vaginal bleeding in 2 h postpartum,rate of neonatal asphyxia between 2 groups (P ＞0.05).Conclusion The effect of phloroglucinol combined with diazepam in prolonged or protracted active phase is remarkable,it can promote the progress of labor,speed up delivery progress,improve the rate of vaginal delivery and decrease the rate of uterine-incision delivery,and no adverse effects on the outcome of perinatal phase,it is worth popularizing.
