This paper summarizes the nursing experience of 9 very low birth weight infants with catheter-related infections. Among the 132 very low birth weight infants with PICC,9 cases suffered from catheter-related infections. Three cases showed positive results on the germiculture of catheter tip and blood, two cases showed positive result only on the germiculture of blood, and four cases showed negative results on both germiculture of catheter tip and blood. One infant's parent gave up the treatment and eight cases were cured. It is suggested that closely monitoring the signs of infections and taking effective treatment and nursing care as early as possible were the key points of infection control.

Objective To evalute the feasibility of a double hand allogroft to reconstuct the limbs'function. Methods A brain dead donor was chosen under the test of blood group in ABO and Rh,HLA match,PRA and the mixed leukocyte culture.The level of the transplantated hands was 5 cm proximal to the wrists The procedure of the allotransplantation was similar to that of the autologous replantation.The immunosuppressants were taken two days before the operation,in the operation and after the operation. The circulation,the vital signs and the rejection were under the supervision. Results The progress was satisfactory. No rejection was found postoperation.After 10 weeks the callus in both ends of radius and ulna was obvious.After 5 months sensation recovered.After 7 months the internal fixation(plates and screws) was removed and tenolysis was done. Now the recipient could use engrafted hands to wash face,make the bed,wear clothes,brush teeth,peel oranges,eat with a spoon,tie the shoelace slowly,pick up a telephoneor and use the conroller of Television. Conclusions With the immunosuppressive agents,the double hands allograft can survive.The growth rate of bone and nerve is faster than that of autologous replantation.

Objective To systematically evaluate the effects of the different postoperative exercise programs on the rehabilitation (such as shoulder range of motion,the incidence of the lymphedema and postoperative complications) of breast cancer patients.Methods The relevant randomized controlled trials which were retrieved from January 2008 to October 2013 were searched in the databases of the Pubmed,Embase,Ovid,Cochrane Library,China Biomedical Literature Database (CBM),China National Knowledge Infrastructure (CNKI),Wanfang Data,VIP.Two reviewers independently screened the literature according to the inclusive and exclusive criteria,extracted the data,and assessed the quality.The RevMan 5.2 software was used for Meta-analysis.Results Finally 10 randomized controlled trial involving 1 110 patients were included.The Metaanalysis showed that progressive exercise program compared to usual exercise obviously modified the shoulder anteflexion [MD =33.04 (26.85-39.23) and 28.05 (21.81-34.30)],abduction [MD =31.06 (8.17-53.95) and 31.39(24.96-37.82)],extorsion [MD=18.47(13.44-23.50) and 16.02(8.35-23.68)] 1 month and 3 months after surgery (P＜ 0.05),extension 1 month after surgery,adduction 3 months after surgery.It also decreased the incidence of the lymphedema.Conclusions It gives us some evidence that the progressive exercise program can promote the rehabilitation of the postoperative breast cancer patients.

Objective To investigate the current status analysis the risk factors of medical adhesive related skin injury(MARSI) in neonates in NICU, in order to provide guidance in prevention and nursing of the skin injury. Methods Convenience sampling five NICU in Shenyang, prospective investigate the incidence of MARSI of neonates during the NICU stay, and analysis the incidence , injury type distribution and risk factors. Results The incidence of MARSI in neonates in NICU was 12.8%(53/413);the major injury type of MARSI was epidermal stripping(47.2%,25/53)and skin tear(35.8%,19/53) in mechanical injury;Logistic analysis showed that the independent risk factors of MARSI were the use of stomach tube, dehydrate skin and blue light therapy (χ2=5.953, 9.806 and 7.568, P<0.05). Conclusions MARSI is frequency interrupted in neonates during the NICU stay, correct selection of medical adhesive products, application of suitable paste and remove skills are helpful to reduce the incidence of MARSI in neonates during the NICU stay.

Objective To compare the applied value of BK virus DNA load detection in urine and plasma for diagnosis BK virus nephropathy (BKVN) in renal transplantation recipients.Method In 88 renal transplantation recipients receiving renal allograft from February 2011 to January 2012 in our institute,BK virus DNA load in urine and plasma was detected by using real-time PCR,and renal biopsy was performed on the recipients with gradual deterioration of the graft function or the loads of BKV replication being very high.The diagnosis of BKVN was confirmed by using immunohistochemistry.Results Of 88 recipients,there were 35 cases (39.8％) of viruria,18 cases (20.5％) of viremia and 5 cases (5.7％) of BKVN.The median BKV DNA load in both urine and plasma in BKVN recipients was significantly higher than in non-BKVN recipients (P＜0.05).The viruria sensitivity and specificity for BKVN were 100％ and 57.3％ (P =0.03),and the viremia sensitivity and specificity for BKVN was 100％ and 82.9％ (P =0.0002),respectively.We regraded viral load ≧ 105 copies/mL in plasma or ≥107 copies/mL in urine as the best discriminant cut-off value to predict the disease and to identify patients at risk of developing BKVAN.The positive cut-off value of urine's positive predictive value (PPV+) was 26.3％ and negative predictive vaule (PPV-) was 95.7％,and the positive cut-off value of plasma's positive predictive value (PPV +) was 83.3％ and negative predictive vaule (PPV-) was 98.8％.Conclusion The viral load ≥105 copies/mL in plasma can be used as the best discriminant cut-off value to predict the disease and to identify patients at risk of developing BKVAN,but the cut-off value of urine should be only used for screening BKV infection.

Objective To investigate the influence of BK virus (BKV) activation in renal transplant recipients on the renal allograft function.Method Recipients receiving renal transplantation during 2010.3-2011.4 were sdected as objectives,the urine and peripheral blood samples of them were taken and real-time PCR assays were performed to detect BKV DNA at 0.5,1,3,6,9,and 12 months post-transplantation.Results Among 88 recipients,BKV viruria occurred in 27 (30.68％) patients,and sustained viruria occurred in 17 patients.37.0％ (10/27) of patients with BKV viruria developed inot BKV viremia,and sustained viremia occurred in 5 patients.The viral load in plasma was higher in patients with sustained viremia than in those with transient viremia (P＜0.05),and serum creatinine concentrations were higher when BK viremia occurred (P＜0.05).Conclusion Graft function was impaired among patients with BK viremia,and regularly monitoring BK virus in renal transplant recipients and clinical imervention based on plasma PCR results can prevent transplant kidney damage effectively.
