Journal of Applied Clinical Pediatrics 1994;0(04):-
Since cardiopulmonary resuscitation(CPR)guidelines was constituted in 1974,it was adopted many times.The American Heart Association,in collaboration with the International Liaison Committee on Resuscitation(ILCOR),adopted new CPR science guidelines in January,2005.This article gives a short introduction of CPR,and showes the progress of several editions.

OBJECTIVE To select the superior one from two skin-cleaning disinfection methods so as to reduce the possibility of hospital infection.METHODS The water plus soaps(control group) and Daniel disinfectants(test group) were used separately to clean and disinfect the skin of patients in intensive care unit(ICU).The degree of skin-cleaning of patients and hand pollution of nurses were observed and analyzed.RESULTS The number of bacteria on the skin of patients of the test group was remarkably lower than that of the control group with a statistically significant difference(t=7.94,P

Objective To investigate the present situation and to analyze related factors of nursing practice environment among 22 public hospitals in Shanghai area.Methods We investigated 1 600 nurses from the 22 hospitals with general information questionnaire and the Chinese version of Practice Environment Scale,and also analyzed related factors by single and multiple factor analysis.Results 1 582questionnaires were taken back.49% were dissatisfied with their working environment,and 28.1% were evaluated to have nice practice conditions.Nurse concerned with workforce management and adequate resources were widespread.Logistic analysis indicated that hospital's level,the nurse's age,educational background and seniority were main factors influencing nurses' satisfaction.Nurse work in tertiary hospitals reported lower satisfaction.Conclusions More attention should be paid on improving nursing practice environment.

OBJECTIVE To investigate the time and dose relation of new urine bio markers in rat model of acute kidney injury induced by genta mycin (GM)to search for more sensitive,noninvasive and specific markers than traditional approaches to monitor nephrotoxicity.METHODS SD Rats were im treated with GM5,20,80 mg·kg -1 or saline once daily.Rats were randomly divided into 20 subgroups:treated for 1 ,3,7,14 d and 14 d followed with 28 d recovery period.Ten rats per group (5 rats per sex)were scarified at 24 h after the last dosing or the end of recovery period.Blood sa mples were col-lected for blood urea nitrogen (BUN)and creatinine(CRE)analysis.Urine was collected at each nec-ropsy for urine protein by dry che mistry method,for kidney injury molecule-1 (KIM-1 )analysis by ELISA, and for β2-microglobulin (β2-MG)analysis by ELISA.Kidneys were obtained for histological exa mination after HE stains.RESULTS Positive protein(3 +)was noted for several fe male animals treated for 7 or 14 d at 80 mg·kg -1 and the tendency of recovery were noted at the end of recovery period.Co mpared with those in saline control group treated for 7 d,the seru m BUN and CRE levels for fe males and the CRE level for males were significantly increased at 80 mg·kg -1 (P <0.05),and the BUN level showed the tendency of increase for males at 80 mg·kg -1 (P >0.05).When treated for 14 d,the seru m BUN and CRE levels for fe males and males at 80 mg·kg -1 and the seru m CRE level for fe males at 20 mg·kg -1 were significantly increased when compared with those in saline control group(P <0.05). The seru m BUN and CRE recovered to base line for all animals treated for 14 d followed by a 28 d recov-ery period.Histopathological observation of kidney tissues indicated that focal tubule dilatation was noted for animals treated for 3 d at 20 and 80 mg·kg -1 ,infla mmatory cell infiltration and focal tubule dilatation were noted at 20 mg·kg -1 and focal renal tubular epithelial cell degeneration,infla mmatory cell infiltra-tion,focal casts (lightly)were noted at 80 mg·kg -1 for animals treated for 7 or 14 d.For animals treated for 14 d followed by a 28 d recovery period,only basophilic tubules and renal casts were noted at 80 mg·kg -1 .New urine bio markers determination indicated that KIM-1 level was significantly increased at 20 and 80 mg·kg -1 for animals treated for 3,7 or 14 d when compared with that in saline control group (P<0.05).For animals treated for 14 d followed by a 28 d recovery period,the KIM-1 level was still significantly higher than saline control group for males and fe males at 80 mg·kg -1 and males at 20 mg·kg -1 (P <0.05 ),but there was evidence for reversal.The β2-MG level was significantly increased at 80 mg·kg -1 for animals treated for 3 d(P<0.05),at 20 or 80 mg·kg -1 for animals treated for 7 or 14 d(P<0.05 or P<0.01 ),when compared with that in the saline control group.For animals treated for 14 d followed by a 28 d recovery period,the β2-MG level was still significantly higher than saline control group for males and fe males at 80 mg·kg -1 and fe males at 20 mg·kg -1 (P <0.05),but there was also evidence for reversal.CONCLUSION Urine KIM-1 and β2-GM are more sensitive and specific markers for early diagnosis of kidney injury induced by GM when compared with the traditional approaches to monitor nephrotoxicity.

A two-step method for the purification of blocking-type anti-human CD80 monoclonal antibody 4E5 from mouse ascites was developed using anion exchange and gel filtration in combination. The ascites was first purified by anion exchange after centrifugation and filtration. The experimental parameters of sample loading and elution were optimized. The optimized loading condition was pH 8.0,50 mmol/L Tris-HCl and satisfactory results were obtained using a 0~0.5mol/L NaCl step elution. The fraction containing the protein of interest was directly loaded on gel filtration column and eluted using a 20 mmol/L phosphate buffer at pH 7.2. The purity of the obtained monoclonal antibody was up to 95% with a recovery of 61%. The purity of mAb could efficiently inhibit the growth of Daudi cells. The amplification of the method was also studied using a Bio-Scale Q5 column and the result was satisfied.
