Objective To define the concept of the benefit finding of breast cancer patients by Morse,Hupcey and Penrod's developed analytical methods.Methods Twenty-two references were recruited through the databases of Medline,Cochrane Library,Embase,Web of Science,ProQuest,according to the inclusion and exclusion criteria.Coding related content of literatures based on the concept of property from Morse terms:boundaries,preconditions and outcome,and from the epistemological,pragmatics,linguistics,logic perspective to evaluate the maturity of the concept.Results The benefit finding of breast cancer patients involved a perception of cognitive processes,including the three attributes,three word boundaries,two preconditions and three results.Development of the concept was not fully mature.Conclusions Clarifying the benefit finding of breast cancer patients can help researchers use the techniques and principles of positive psychology to promote the benefits finding of breast cancer patients and the patients' physical and mental rehabilitation.

Objective To evaluate the effect of preoperative ambroxol aerosol inhalation on postoperative lung complications in patients with chest and abdominal surgery.Methods The randomized controlled trials (RCTs) taking preoperative ambroxol aerosol inhalation interventions were collected from the databases of Chinese Technology Journal Database,China National Knowledge Internet and Wanfang Database.Data were analyzed with RevMan 5.0 software.Results Eleven articles with 1 160 patients met the inclusion criteria.There was a certain heterogeneity across the analysis,which might result from kind of included patients,inhalation method,difference of the medication,inhalation time,etc,according to subgroup analysis.The result showed that compared with the control group,patients in the experimental group had lower incidence of postoperative lung complications and the differences were not statistically significant.Conclusions The Meta analysis had identified a significant effect of preoperative ambroxol aerosol inhalation on postoperative lung complications in patients with chest and abdominal surgery,but high quality were in need.

Objective To compare the preoperative eternal nutrition bowel preparation method with the conventional method in the intestinal cleansing effect,postoperative infection and postoperative complications of gastrointestinal function recovery time,and to provide reference for selection for our clinical preoperative practice.Methods Computer Retrieval of Chinese Biomedical Literature Database,VIP Chinese Science and Technology Journal Full-text Database and China Academic Journal was conducted.The time limit was from establishment of database till May 2013.The research type was randomized controlled trial.Two investigators independently screened,assessed quality and extracted data according to the inclusion and exclusion criteria for literatures,and cross-checked them using RevMan 5.0 software for Metaanalysis,then applied the grading method recommended by the GRADE grading system.Results Ultimately seven RCTs were included,with a total of 478 cases of colorectal cancer patients.Compared with conventional preoperative bowel preparation,eternal nutrition method showed similar bowel cleansing effects and the incidence of complications,but it could shorten the postoperative recovery of gastrointestinal function time,lower positive rate of abdomen,intestine shedding of tumor cells,improve postoperative albumin and transferritin levels.Conclusions Eternal nutrition alternative method for bowel preparation before colorectal surgery is safe and effective.

ObjectiveTo evaluate the reliability and validity of Chinese version of Postoperative Pain Assessment Nursing Practice Questionnaire (PPA-NPQ).MethodsA forward-backward translation procedure was followed to develop the Chinese version of PPA-NPQ.A total of 258 surgical nurses were investigated by the revised Chinese version dimensions of PPA-NPQ,then the results were tested on reliability and validity by SPSS17.0.ResultsThe cronbach's α of the Chinese version of PPA-NPQ was 0.889.The split- half coefficient and testretest reliability of PPA-NPQ were 0.729,0.875 respectively ; the Cronbach's a,split- half coefficient and test-retest reliability of each sub-scale were ranged from 0.820-0.857,0.797-0.862,0.846-0.902 respectively.The correlation between each sub-scale and total scale were ranged from 0.704-0.818 (P ＜ 0.01 ).ConclusionThe revised Chinese PPA-NPQ is reliable and valid,and can be used to test the level of postoperative pain assessment practice by surgical nurse.

Objective To develop a method for the determination of trace mercury in waste water by atomic fluorescence spectrometry. Methods The mercury vapor was generated with the hydride generation agent potassium tetrahydroborate (KBH4) in hydrochloric acid. The optimum working conditions of the instrument were studied, including flow rate of carrier gas, concentration of potassium tetrahydroborate solution and acidity of sample solution. Results Under the optimum condition, the linear range of determination was 0-20 ng/ml, the detection limit was 0.04 ng/ml, the relative standard deviation was 1.9% (n=11) for 5 ng/ml Hg, the recovery rate was in the range of 96%-104%. Conclusion This method is applicable to the determination of mercury in the waste water.

84 eyes that underwent femtosecond laser-assisted laser in situ keratomileusis ( FS-LASIK) , and 110 eyes that underwent small incision lenticule extraction ( SMILE) surgery were included in this prospective case se-ries study. HOAs included ( total HOAs, spherical aberration, horizontal coma aberration, and vertical coma aber-ration) were measured preoperatively after 1 week, 1 month , and 3 months postoperatively by Pentacam. The ab-errations were described as Zernike polynomials. Significantly increased total HOAs and SA and significantly de-creased vertical coma were noted at 1 week, 1 month, and 3 months after FS-LASIK ( P<0.05 ) . However, no significant increase was found in postoperatively horizontal coma. There were significant increases in total HOAs, SA, and horizontal coma and a decrease in the vertical coma at each postoperative examination in SIMLE group ( P<0.05 ) . The total HOAs and SA were significantly smaller in SMILE group than that in FS-LASIK group at 1 week, 1 month, and 3 months postoperatively. The changes in total HOAs and SA were also significantly smaller in SMILE group than that in FS-LASIK group at each postoperative examination. Compared with FS-LASIK, SMILE can induce fewer total higher-order aberrations and spherical aberration after operation.

Objective To explore the relationship between first-episode schizophrenia and metabolic syndrome (MS). Methods 231 first-episode schizophrenia patients (schizophrenia group) and 63 healthy controls (healthy group) were selected to detect the height, weight, waistline, fasting plasma glucose (FPG), blood lipid and blood pressure. International Diabetes Federation (IDF) MS Diagnostic Criterion (2005) was used to diagnose MS. Results The FPG and Total Cholesterol (TC) of the schizophrenia group were significantly higher than the control group (P<0.001). The MS detection rate in the schizophrenia group was higher than in the control group (P=0.021). Conclusion First-episode schizophrenia patients could have glucose-lipid metabolism disorder during the early stage.

[Summary] A selection of 528 unrelated subjects were enrolled(198 males, 330 females) with the mean age of(52. 23 ± 13. 41) years old. According to body mass index, 253 persons belonged to the normal weight group and 275 persons overweight/ obesity group. A total of 10 SNPs in CIDEB and CIDEC genes were detected. SHEsis online were used to get the haplotypes of these two genes. The relationship between above SNPs and obesity were analyzed under additive inheritance pattern. The main effects and interaction on obesity induced by two genes’ haplotypes were analyzed by logistic regression. rs2144493 in CIDEB gene was associated with obesity, C was a protective alleles, OR (95% CI) equals 0. 722(0. 525-0. 992). CCTT haplotype of CIDEB gene carriers and GCG haplotype of CIDEC gene carriers were more prone to obesity or overweight, there was an interaction between the haplotypes of 2 genes. CIDEB, CIDEC haplotypes may play independent and interactive roles in causing obesity.

Objective To evaluate the effect of the empowerment theory-based health education on anxiety, depression and self-efficacy in the major caregivers for patient with leukemia. Methods Eighty patients with leukemia and their caregivers were enrolled during November 2013 to November 2014 and were divided into the intervention group (n=40) and the control group (n=40). The caregivers of the intervention group received empowerment theory-based education , while those of the control group received general health education. The two groups were compared in terms of anxiety, depression and self-efficacy. Results Before intervention, there were no significant differences in the three items between the groups (P>0.05). After intervention, the level of self efficacy in the intervention group was better than that in the control group (P<0.05) and the scores in the intervention group were significantly lower than those of the control group. Conclusion The empowerment theory-based education can relieve anxiety and depression and improve the self efficacy of the caregivers of patients with leukemia.
