Objective:The separation effect for the enantiomers of ketoprofen on four diferent chiral columns was investigated and established a sensitive and stereospecific HPLC separation and determination method for ketoprofen enantiomers in animal plasma.Methods:The enantiomers of ketoprofen was resolved in the normal phase mode by using n-hexane∶isopropanol∶TFA(80∶20∶0.02)as mobile phase with UV detector at a wavelength of 254 nm.The flow rate was 1.0 ml/min.Results:Linear calibration curves were obtained in the range 0.1～10?g/ml for R-(+)-ketoprofen(r=0.999 8)and S-(+)-ketoprofen(r=0.999 6)in plasma.The detection limit(S/N=3) was 2 ng for each enantiomer.Conclusion:This method is simple,fast and can be used to detect optical purity of S-(+)-ketoprofen and monitor pharmacokinetic studies of ketoprofen enantiomers.

Congenital heart disease is a type of common birth defect and most can be cured by surgery with prominent prolongation of life expectancy.But,different kinds of arrhythmias accompanied by congenital heart disease,especially late onset postoperative arrhythmias have become one of the major causes of mortality in these patients.Management and effective treatment for fast and slow arrhythmias associated with congenital heart disease are quite critical.

Objective To investigate the association between -45C→G mutation at promoter of human urate transporter 1 gene and primary hyperuricemia. Methods The allele frequency and genotypo distribution of -45 C→G mutation at promoter of human urate trans-porter 1 gene were determined by PCR-RFLP in 217 patients with primary hyperuricemia and 419 normal controls. Results The frequencies of the G allele and CG genotype at promoter of human urate transporter 1 gene in patients were significantly higher than that in normal controls (P = 0. 031, P = 0.031). The levels of serum uric acid (UA) and triglyceride (TG) in subjects of CG genotype were significantly higher than those in the objects of CC genotype(t=3.058, t=3.699, P=0.002, P<0.001). There were no significant difference in the levels of total cholesterol (TC), fasting plasma glucose (FPG), urea nitrogen (BUN), creatinine (Cr) between the two groups (P>0.05). Conclusion The -45 C→G mutation at promoter of human urate transporter 1 gene may be related to primary hyperuricemia.

Twenty cases of infantile eczema were treated by combination of Tuina therapy and Western medications, and 18 cases were treated by Western medications. The therapeutic effective rate was respectively 100% and 90.0% in the two groups, with a difference between them (P＜ 0.01).

Objective To investigate the knowledge,attitude and related factors associated with HIV/AIDS among female prisoners in Shaanxi province.Method A cross-sectional survey with questionnaire was conducted in 837 female prisoners.Results Of the studied female prisoners 94% had heard of HIV/AIDS.The rate of correct answer on basic knowledge about AIDS was 19.8%-87.3%.The rate of correct answer on the transmission route was 11.6%-87.6%.The rate of correct answer on non-transmission route was 23.4%-48.6%.The rate of correct answer on prevention was 36.7%-57.5%.Of them 46.6%-55.7% were afraid of AIDS,and 26.6%-90.0% had prdjudice and stigma to HIV/AIDS and PLWHA(people living with HIV/AIDS).The factors affecting HIV/AIDS related knowledge included marriage status,career,education background and number of family members.The factors affecting attitude included age and education background.Conclusion The studied female prisoners have wide but superficial knowledge about HIV/AIDS and have expressed over fear for HIV/AIDS.They also cannot tolerate AIDS patients.

Objective:To explore the relationship among the cancer-related fatigue,coping styles and quality of life in breast cancer patients with chemotherapy.Methods:A total 120 female breast cancer patients were selected as the subjects.The instrument used for data collection was a questionnaire that was composed of four parts:the demographic data form,the Revised Piper Fatigue Scale (PFS),Jalowiec Coping Scale (JCS),Quality of Life Questionnaire-Core 30 (QLQ-C30),and Quality of Life Questionnaire-Breast 23 (QLQ-BR23).The statistical software SPSS was used for data analysis.Cancer-related fatigue,coping styles,quality of life and their related factors were determined by nonparametric tests.Spearman correlation coefficient was used to investigate the relationship among cancer-related fatigue,coping styles and quality of life in breast cancer patients with chemotherapy.Results:There was a significant negative moderate correlation between cancer-related fatigue and the quality of life (r＝-0.24,P<0.01),and negative correlation between cancer-related fatigue and the total health status (r＝-0.39,P<0.01).The positive coping styles including optimistic and confronting were negatively correlated with cancer-related fatigue (r＝-0.25,-0.18，Ps<0.05),and were positively related to the functional domain of quality of life(r＝0.35，0.21， Ps<0.05).The positive coping styles including emotive,fatalistic,and palliative were positively correlated with cancer-related fatigue (r＝0.25,0.18,and 0.28， Ps<0.05),and were negatively correlated with the functional domain of quality of life (r＝-0.40,-0.32，Ps<0.05),and emotive and fatalistic were positively related to the symptomatic domain of quality of life(r＝0.40,0.28,Ps<0.05).Conclusion:There exists a certain degree of correlation among cancer-related fatigue,coping styles and quality of life in breast cancer patients with chemotherapy,which may guide the clinical care.

Objective To investigate the relationship between plasma lysophosphatidic acid(LPA) concentration and progression of aortic atherosclerotic lesions for hyperlipidemic diet fed infantile rabbits.Methods Two-month-old infantile rabbits(0.9-1.1 kg) were randomly assigned to normal diet group(group A,n=6) and hyperlipidemic diet group(group B,n=11).Blood lipid levels,LPA,nitric oxide(NO),malondialdehyde(MDA) and superoxide dismutase(SOD) concentrations were taken regularly.The thoracic aorta was taken from a hypertipidemic diet rabbit for pathological study at certion interval of time.Results Electronic microscope analysis revealed subtle changes of aortic wall during 1-2 weeks of the experiment.Fatty streaks(FS) appeared after 4 weeks of hyperlipidemic diet.The degree of FS increased gradually thereafter.Blood lipid levels increased significantly after 1 week of hyperlipidemic diet.Plasma LPA concentration reached its peak level before the appearance of FS.The NO,MDA and SOD concentrations of group B changed significantly proportional to the development of FS.Conclusion Measuring plasma LPA concentration,combined with serum NO,MDA and SOD concentrations can accurately reflect the formation and progression of FS.

OBJECTIVE:To investigate the relationship between the perioperative application of antibiotics in caesarean opera-tion and neonatal hyperbilirubinemia,and to provide reference for reducing the incidence of neonatal hyperbilirubinemia. METH-ODS:264 cases of cesarean section women were randomly divided into control group and observation group,with 132 cases in each group. Control group was given antibiotics after operation,and observation group was given prophylactic application of antibi-otics before operation,and equivalent dose of intravenous injection after operation. Postoperative maximum and average tempera-ture,white blood cell(WBC),neutrophils(NEUT),complications and economic index were compared between 2 groups after op-eration. RESULTS:There was no statistically significant difference in postoperative maximum and average temperature,WBC count,NEUT proportion,wound infection and fever rate between 2 groups (P>0.05). The costs of medication,drug dosage per capita,hospital stay and the incidence of neonatal hyperbilirubinemia in observation group were significantly lower than in control group,with statistical significance (P<0.05). CONCLUSIONS:The perioperative standard use of antibiotics in caesarean opera-tion could effectively reduce the incidence of postoperative neonatal hyperbilirubinemia and hospitalization cost,and cut down treat-ment time. It also has a high economic value and worthy of promotion.

Objective To explore the interactions mechanism of job embeddedness of nurses with psychological capital,organizational commitment,intention to stay and their influencing factors.Methods By convenient sampling method,722 nurses were investigated with Job Embeddedness Questionnaire, Psychological Capital Questionnaire,Organizational Commitment Questionnaire and Nurses′Intention to Stay Questionnaire.Path analysis was made on relations between the variants.Results Night shift intervals pose positive influence on nurses′psychological capital,organizational commitment and intention to stay.Psychological capital can influence job embeddedness by both directly and indirectly,and can influence their intention to stay indirectly.Organizational commitment can influence job embeddedness strongly and directly (r = 0.494 ),and their intention to stay both directly and indirectly.Job embeddedness can influence their intention to stay directly (r=0.453 ).The model fitting is found desirable.Conclusions Nursing managers can enhance nurses′organizational commitment by developing the psychological capital to enhance nurses′organizational commitment effectively.Nurses with higher level of psychological capital and organization commitment will embed into their workplace more deeply, then increasing their intention to stay ultimately.
