Objective To investigate nurses' satisfaction to APN scheduling,and analyze the impact of APN scheduling on nurses' work and their families.Methods To investigate the satisfaction of 51 practicing nurses in two sections to APN scheduling using the self-designed questionnaires. Cronbach' s a of the questionnaire was 0.724.Results Satisfaction of the married,highly educated nurses were 69.75％ and 88.89％,respectively; and satisfaction of the unmarried and lower education nurses were 39.29％ and 47.62％ ; the differences were significant ( x2 =4.647,5.098,respectively ; P ＜ 0.05 ).APN scheduling was thought to enhance the cooperation between the nurses,increase the communication chance,strength the amateur time and alleviate the psychological pressure.Conclusions Nurses were more satisfied with APN scheduling than the traditional work schedule.APN scheduling work shifts considered on the nurses' health,family life and their part-time study.This work schedule is humane and scientific,and can help to mobilize the enthusiasm of nurses and stable team of nurses.

Objective To investigate the efficacy of intracoronary tirofiban during percutaneous coronary intervention(PCI)for patients with acute myocardial infarction(AMI).Methods Seventy-six consecutive AMI patients,treated with primary coronary angioplasty in 12 hours were enrolled.They were randomly divided into two groups:tirofiban group(39 cases)and control group(37 cases).Tirofiban group was treated with intracoronary timfiban during PCI and after the operation for 48 hours.Both of them were given heparin in PCI and aspirin,clopidogrel before PCI.At the end of PCI procedure,angiographic features such as TIMI flow grade and TIMI myocardial perfusion grade(TMPG)were analyzed.The difference of two groups in complication and major adverse cardiac events(MACE) was investigated.Results The myocardial reperfusion of tirofiban group was better than that of control group[TIMI grade 3 flow 94.9%(37/39) vs 78.4%(29/37),P<0.05;TMPG 3 grade 89.7%(35/39)vs 67.6%(25/37),P<0.05].There was no significant difference between two groups in bleeding complication.The occurrence of MACE in tirofiban group was less than that in control group[7.7%(3/39)vs 18.9%(7/37),P<0.05].Conclusion Intracoronary tirofiban dunng primary PCI in patients with AMI can improve coronary flow and myocardial perfusion,and has no more bleeding and less MACE occurrence.

Sixty four patients undergoing endoscopic sinus surgery were randomly divided into two groups.In nimesulide group (n=32) patients were given nimesulide capsule 100 mg after surgery and 32 patients in control group were given 100 mg vitamin C as placebo.The visual analogue scale (VAS) was used to evaluate the degree of pain during withdrawing nasal packing.The VAS value of the nimesulide group was 2.8±1.1 3 h after surgery and 2.7±1.2 during with drawing nasal packing,that of control group was 6.7±0.6 and 8.3±0.6,respectively (both P<0.01).The results revealed that nimesulide had a siguificant analgesic effect in endoscopic sinus surgery.

Objective To explore the possibility of non-discarding blood after cisplatin hyperther-mic antiblastic perfusion(HAP)in treating the patients with malignant bone tumor of lower extremity.Methods Forty patients consisted of 31osteosarcomas and9malignant fibrous histiocytomas of bone.The clinical stages were wholly classified intoⅡB stage according to Ennekings surgical staging system for muscu-loskeletal tumors.The patients were divided into three groups:group1:discarding blood group(10cases),in whom200ml of the400ml blood remaining in heart-lung machine was discarded after HAP;group2:Non-discarding blood group(25cases),the blood remaining in heart-lung machine was not discarded after HAP and re-infused into systemic circulation;group3:systemic chemotherapy group(5cases),cisplatin was infused intravenously.The regional and the systemic blood cisplatin concentrations were determined at3,30and60minutes during HAP,and the systemic blood cisplatin concentrations were determined at0,0.5,1,2,4,8,12,24,48and72hours after HAP in the group1and group2.While1h after cisplatin infusion in-tra venously in the group3,the blood cisplatin concentration were also measured.Results The regional blood cis platin concen tra tions were high er than that in systemic blood at the time during HAP.The systemic blood cisplatin concen trations after HAP,ex cept at0minute in the group2were higher than that in the group1,there were sig nificant statistic differences between the two groups.The systemic blood cisplatin con-cen trations after HAP in the group2were simi lar to that after systemic chemotherapy.No severe adverse ef-fects in the group1were found.The Ennek ings surgical stagings for the tumors were turned fromⅡB intoⅡA in all the patients.Conclusion The method of non-discarding blood after HAP is available,it is not only local treatment ,but also systemic chemotherapy in the patients with malignant bone tumor of lower ex-tremi ty for limb-salvage surgery.

?Advances in genome-wide analysis have revealed that up to 90%of the human genome is transcribed.However, only approximately 1% of RNA transcripts encode proteins, and the remaining transcripts are noncoding RNAs.Noncoding RNAs can be roughly divided into small noncoding RNAs (<200nt ) and long noncoding RNAs ( LncRNAs, >200nt ). Small noncoding RNAs include microRNAs, transfer RNAs and small nucleolar RNAs, whereas the long noncoding RNAs comprise ribosomal RNA, natural antisense transcripts, etc. Although the biosynthesis and biological activities of microRNAs are well studied through bioinformatics and active biological molecules analysis, the understanding of LncRNAs on these aspects is still limited.LncRNAs play multiple roles in regulating gene transcription and translation, and epigenetics.Aberrant LncRNAs expression can occur in various pathological processes and significantly related to the pathogenesis or poor prognosis of ophthalmological diseases. In this review, we will focus on the characteristics and regulatory functions of LncRNAs that are commonly associated with ophthalmological diseases.

Objective To analyze the electroencephalograph (EEG) features of 43 patients with clinically possible or probable Creutzfeldt-Jakob disease (CJD) and its correlation with megnetic resonance imaging (MRI) imaging and clinical manifestations.Methods All patients diagnosed with suspected CJD who were hospitalized in Xuanwu Hospital from January 2013 to December 2015 were collected.The clinical data, EEG and MRI imaging features were analyzed retrospectively.Based on the periodic sharp wave complexes (PSWC) appearance in EEG results, the patients were divided into typically changed group (TCG), atypically changed group (ACG) and unchanged group (UCG).Age, disease duration, clinical manifestations and MRI features among three groups were analyzed and the correlations between patient′s EEG features and age, disease duration, clinical manifestations or MRI features were explored using spearman method.Results Among the 43 patients with possible or probable CJD disease, 26 were male and 17 were female with an average disease duration of 4 months.The age of onset ranged from 31 to 80 with an average of (58.0±9.8) years old, and 86.0% of patients were 51 years old or above.Clinical characteristics of CJD patients according to occurrence rate were as follows: 35 cases (81.4%) with cognitive impairment, 29 cases (67.4%) with mental and behavior disorder, 28 cases (65.1%) with pyramidal tract damage, 24 cases (55.8%) with cerebellar symptoms, 23 cases (53.5%) with extrapyramidal symptoms,17 cases (39.5%) with myoclonic, 13 cases (30.2%) with dyssomnia, 13 cases (30.2%) with visual disorder and 2 cases (4.7%) with akinetic mutism.Regarding EEG features, 39.53% (17/43) of patients showed typical periodic sharp wave complexes (PSWC) (TCG group), 51.2% (22/43) had irregular rhythm and different forms of slow wave (ACG group) and only 9.3% (4/43) had no EEG change (UCG group).The occurrence rate of ribbon sign in MRI was 82.4% (14/17) in TCG group, 77.3% (17/22) in ACG group and none in UCG group.The rates were significantly higher in TCG and ACG group than that in UCG group (both P<0.05).Spearman correlation analysis revealed that EEG features was correlated with disease duration (r=0.351, P=0.021) and visual impairment (r=-0.377, P=0.013) for all CJD patients.There was no correlation between EEG and MRI or other clinical manifestations such as myoclonic, age and so on (all P>0.05).Conclusions EEG showed typical changes associated with disease duration in different stages of disease.EEG and MRI are two different means to evaluate different aspects of patients with CJD disease, and combination of two means could achieve better evaluation results.

The excipient processing is an essential part of traditional Chinese medicine processing, and understanding its scientific connotations is a critical scientific issue that urgently needs resolution. Building upon a foundation where the composition of traditional Chinese medicine substances is fundamentally clear, this paper applies the techniques and methods of chemoinformatics to the study of the excipient processing mechanism. Relevant information on traditional Chinese medicines processed with four kinds of excipients (wine, vinegar, salt and honey) was collected, including properties, taste, meridian tropism, chemical components, etc. Molecular descritors and skeletons corresponding to each chemical component were calculated using chemoinformatics to characterize the properties and structural features of the components. Characteristic components associated with the four excipients (wine, vinegar, salt and honey) were explored through multivariate statistical analysis and Murcko skeleton analysis. Further analysis, taking honey-processed Astragali Radix as an example, the focus was on the impact of the processing excipient honey on the solubility and permeability of its characteristic pharmacologically active components (isoflavones). It was discovered that the excipient honey can increase their solubility and permeability, emphasizing that the impact of processing excipients on the pharmacological classification properties is a key breakthrough in elucidating the mechanism of excipient processing. In summary, this study analyzed the characteristic components associated with the processing excipients "wine, vinegar, salt and honey" based on their composition characteristics, providing data support for the research on the mechanism of excipient processing from a biopharmaceutical perspective.

Objective To evaluate the role of postmastectomy radiotherapy in four subgroups of high-risk breast cancer patients, who were grouped by the status of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor 2 (Her-2). Methods A total of 437 invasive breast cancer patients with T3-4N1 or N2-3 and available immunohistochemistry results of ER, PR and Her-2 were retrospectively analyzed. Patients were classified into 4 subgroups according to hormone receptors (ER or PR, Rec) and Her-2 status:Rec-/Her-2-(triple negative), Rec-/Her-2 +, Rec +/Her-2 + and Rec +/Her-2-. Rec-was defined as ER-and PR-. Rec + was defined as ER + and/or PR +. Her-2 positive was defined as Her-2 + + or Her-2 + + +. End points were isolated locoregional recurrence (LRR), distant metastasis (DM), disease-free survival (DFS) and overall survival (OS). Results The median follow up time was 48 months. Sixty-nine (15. 8%) patients were Rec-/Her-2-, 62 (14. 2%) Rec-/Her-2 +, 89 (20.4%) Rec +/Her-2 + and 217 (49.7%) Rec +/Her-2-. 480(93.4%) patients received chemotherapy and 352(80. 5%) received radiotherapy. Radiotherapy significantly reduced the 5-year LRR rates of all the four subgroups (Rec-/Her-2-: 13.1% vs. 33. 3%, Rec-/Her-2 + :9. 3% vs. 21.2%, Rec + /Her-2 + :9. 7% vs. 47.0%, Rec +/Her-2-:3. 2% vs. 15.4%). Radiotherapy significantly lowered the 5-year DM rates (26. 7% vs. 49.4%, 27.6% vs. 67. 5%, 18.4% vs. 100%) and improved the 5-year DFS rate (66. 7% vs. 33. 3% , 67.7% vs. 33. 3% , 72. 6% vs. 0%) as well as OS (73.9% vs. 25.2% ,69. 8% vs.41.5%, 91.0% vs. 32. 8%) of patients with Rec-/Her-2-, Rec-/Her-2 + and Rec +/Her-2 +. Conclusions In high-risk breast cancer patients, all subgroups of patients grouped by ER, PR and Her-2 status can benefit from postmastectomy radiotherapy.

Objective To evaluate the efficacy of microvasoepididymostomy for the treatment of obstructive azoospermia. Methods Ninety-eight patients were confirmed as obstructive azoospermia by infertility investigations.The mean (range) age was 31 (20-43) years.The mean duration of obstruetion was 4 years.All patients were seen by the surgeon for a complete history and physical examination.Semen analyses proved azoopermia,serum levels of sexual hormone were normal and testicular function for production of sperms were normal certified by biopsy.All patients with suspected epididymal or vasal obstruction were offered scrotal exploration.The decision for microvasoepididymostomy was made during surgery,based on the pateney of the vas towards the abdomen documented by saline and sperm fragments containing in the epididymal fluid on intraoperative light-microscopic examination.Microvasoepididymostomy was performed in 58 patients documented epididymal obstruction The initial semen analysis was then done after usually 3 months postoperatively.Patency was arbitrarily defined as＞10 000 sperm/mL in ejaculate in at least one semen analysis after surgery.Postoperative patency rate and postoperative impregnation rate were followed. Results Fifty patients were followed up for 3-29 months,8 cases lost.Sperm was found by semen analysis in 36 patients.Sperm density was 4×104-2×108 sperms/ml and motility was 2%-70%.Semen analysis reveals azoospermia in 6 patients and the patients were counseled to undergo further testing to determine the ultimate outcome of the procedure.Natural conception occurred in 14 patients followed for more than 12 months.The overall pateney rate was 72%(36/50).Among patients with a follow-up of＞6 months,the natural paternity rate was 28%(14/50).The median time to achieve a natural pregnancy was 6.6 (4.0-10.0)months. Conclusion A more favourable patency can be achieved using microsurgical intussusception vasoepididymostomy and a part of patients with obstructive azoospermia can be cured by this means.

Objective To compare the circumferential approach and suprapubic approach for correcting the concealed penis. Methods Thirty-four patients received circumferential approach (group A,18 cases)or suprapubic approach(group B,15 cases)randomly for the concealed penis.The length of penis without erection before and after surgery treatment,patients'satisfaction and surgical complications were evaluated.All the patients were followed at least 6 months after operation.Results The penile length before and after surgery in group A were(1.78±0.41)cm vs(3.97±0.47)cm,the length of the postoperative penis was significantly longer than that of the preoperative penis(P<0.01).83%of those in group A(15 cases)were satisfied with the cosmic results.The length of preoperative and postoperative penis in group B were(2.07±0.53)cm vs(4.05±0.81)cm respectively,the length of the postoperative penis was significantly longer(P<0.01).Satisfaction was 87%(13 cases).The postoperative penile length between the 2 groups was not different(P> 0.05).Prepuce edema was reported to Occur in 56%and 13%in group A and group B and spontaneously disappeared within 3 months.Fat synchysis occurred in 2 of group B. Conclusions The cosmic effect of the 2 surgical approaches is similar,but circumferential approach is simpler.There is no serious complication in those receiving circumferential approach.
