Through analyzing medical personnel's duty under Bio-psycho-social Medical Mode, this paper states that medical personnel's duty should be emphasized not only on preventing and curing diseases, but also on solving patients' psychological problems.Therefore it states that death education, first, to medical professionals themselves,second,to the patients and their family,is very important,at last it also inquires into the mode of death education.

5 cm in diameter) of soft tissue density with irregular margins in sacrococcygeal region in all patients,the masses were of homogeneous density,no calcification and sacrococcygeal bone erosion,the CT value was 34~24 HU.The organs around the lesions were compressed and displacement.Conclusion In infants,huge homogeneous soft tissue-like and non-calcific mass with irregular margin in the sacrococcygeal region accompanied by bony destruction,hemangiopericyte sarcoma should be considered.

Objective To assess patients' self-management behaviors and examine factors influencing self-management behaviors in patients undergoing maintenance hemodialysis.Methods This research was conducted as a descriptive survey by 125 patients from a hemodialysis clinic in Tianjin.The data were collected with self-management behaviors questionnaire of hemodialysis patients and self-efficacy scale for managing chronic disease.Results Regression analysis revealed sex,educational level and selfefficacy were independent predictors for self-management behaviors.Conclusions Hemodialysis patients' self-management behaviors need to be improved in the future.Healthcare professionals should recognize the factors hindering self-management behaviors from the patients' perspective while assisting them with appropriate skills in making behaviors changes possible.

AIM　To elucidate the structure of the glycan of SPPA-1, a glycoconjugate isolated from Spirulina platensis. METHODS　Methylation analysis, GC/MS, and 1D, 2DNMR techniques were used to determine the structures of the glycoconjugate (SPPA-1). RESULTS　SPPA-1 was only composed of α-D-glucose and shown to be a (1→4) linked α-D-glucan to which a few glucosyl side chains are attached at O-6 of the glucosyl residues of the main chain. CONCLUSION　The glycan of SPPA-1 is a new glucan.

AIM　To determine the effects of glycoconjugates and their glycans from Lycium barbarum L. on inhibiting low density lipoprotein (LDL) peroxidation. METHODS　Using Cu2+-induced oxidation as a model, the oxidative production of thiobarbituric acid-reactive substances (TBARS) and the LDL electrophoresis migration on agarose gel were measured. RESULTS　The effects of glycoconjugates and their glycans from Lycium barbarum L. on inhibiting LDL peroxidation were different, among them, glycoconjugate LbGp5 showed the best effect on inhibiting LDLperoxidation. CONCLUSION　The glycoconjugates can inhibit LDL peroxidatin while their glycans showed no effects on inhibiting LDL peroxidation.

Objective To compare the outcome of laparoscopic with open partial nephrectomy for duplication anomalies. Methods A total of 64 patients with mean age of 17 months were divided into 2 groups.Open group consisted of 36 patients,and laparoscopic group consisted of 28 patients.In open group,there were 19 boys and 17 girls,15 cases were of ectopic ureter,18 of ureterocele,2 of vesicoureteral reflux (VUR) and 1 of ureteropelvic junction obstruction.Mean age was 18 months.In laparoscopic group,there were 18 boys and 10 girls,9 were of ectopic ureter,16 of ureterocele and 3 of VUR.Mean age was 1 6 months.There were no significant differences in age and diseases.Results There were 2 conversion to open surgery in laparoscopic group and no other intra-operative and post-operative complications in 2 groups.Mean duration of operation was 2.5 h for open group,the difference of pre- and post-operation hemoglobin was 2.64 g,the volume of drainage was 91.4 ml,the time of drainage was 4.2 d and mean hospital stay was 19.3 d.In Iaparoscopic group,the figures were 2.9 h,1.45 g,55.4 ml,3.4 d and 14.3 d,respectively.The differences of the figwres were significant between the 2 groups (P＜0.05). Conclusion Laparoscopic partial nephrectomy is effective and safe for the treatment of duplicated kidney with a dysfunctional moiety.

Case teaching has evident characteristics compared with traditional theory teaching. This article expound the purpose,significance,teaching process and the noticeable problems of case teaching in medicaI ethics teaching.

Medical Ethics Committee founded in medical orgnizations,universities,academic periodicals and hygiene institutes is an international regulation in the filed of medicine.Although we have done a large amount of work to be in line with international standards,there are still some problems such as no systemic roles,function deficiencies etc.Therefore,we should study its establishing background and main function and strengthen its construction.

A polysaccharide SPPC 1 was isolated from spirulina platensis by acetone fractional precipation, free protein was removed by trichloroacetic acid(TCA). Purification of the polysaccharide by Sephadex G 75 colume and CM Sephadex C 50 colume.The homogeneity of this polysaccharide was proved by HPLC and CE. molecular weight was 1.62?10 6. GC showed that the glycoconjugate was composed of Rha,Xyl,Man and Glc. Molar ratio is Rha:Xyl:Man:Glc=6.24:0.37:0.13:0.71. IR, 1HNMR spectrum indicated the presence of ? linkage glycoside. ESR experiment showed that SPPC 1 could eliminate O . 2 radicals.

Objective To study the effect of Shengmai injection on the platelet parameters and CD4+CD25+cells in peripheral blood of patients with chronic lymphocytic leukemia,and to explore the optimal regimen for patients with chronic lymphocytic leukemia.Methods One hundred and twenty patients with chronic lymphocytic leukemia were enrolled in this study from January 2012 to December 2014.(D1),vincristine 4mg(d1),prednisone 60 mg/d(d1-5)were given to the CHOP regimen in the control group: cyclophosphamide 600 mg/m2(d1),doxorubicin 25 mg/m2(d12)28d a course of treatment,a total of 4 courses,the observation group of patients in the control group of patients treated on the basis of Shengmai injection,compared the two groups of patients with chemotherapy,platelet parameters and serum CD4+CD25+T cells and Th17 cells.Results After treatment,the PLT,MPV and PDW of the observation group were(215.4± 31.7),(9.5±2.5)and(16.9±2.4),respectively,which were significantly higher than those of the control group.The CD4+CD25+T cells in the observation group were(1.5±0.8)The total effective rate of the control group was 35.0％,the total effective rate was 35.0％,and the total effective rate of the control group was 35.0％.There were significant difference between the control group and the control group(P<0.05),The difference was statistically significant.Conclusion Shengmai injection combined with CHOP regimen in chronic lymphocytic leukemia patients can improve immune function,promote platelet growth,improve platelet clinical parameters,and help improve the efficiency of chemotherapy,compared with CHOP alone Program treatment is better,worthy of clinical application.
