Objective In order to reduce neonatal missing and obstetric malpractice,design and application of a new neonatal hand ring was proposed in this paper.Methods Positive stop button,positive stop knot,positive stop cannula,rope,double sandwich tag set were included in the structure of new neonatal hand ring.Results The new neonatal hand ring has been experimentally applied by some departments in Nanjing Maternity and Child Health Care Hospital.The result showed the new neonatal hand ring effectively reduced the incidence of hand ring falling off,arm erythema and beds error.Conclusions Application of the new neonatal hand ring can guarantee the legal rights of newnates,avoid the disputes caused by misunderstanding and increase the automatic management level of hospitals.

Objective To evaluate the effect of curcumin on diabetic neuropathic pain (DNP) in rats. Methods Forty-eight male SD rats weighing 200-230 g were randomly divided into 6 groups ( n = 8 each) : group Ⅰ normal control (group C); group Ⅱ DNP (group D) ; group Ⅲ DNP+ DMSO (solvent of curcumin) (group DD) and group Ⅳ , Ⅴ , Ⅵ DNP + curcumin 50, 100 or 200 mg/kg ( group DC50, 100, 200 ). Diabetes was induced with intraperitoneal (IP) streptozocin 75 mg/kg in group Ⅱ -Ⅵ. Curcumin 50, 100 and 200 mg/kg were given IP once a day for 14 consecutive days starting from 14 d after streptozocin in group Ⅳ , Ⅴ and Ⅵ respectively. Venous blood samples were taken before and 72 h after IP streptosocin for determination of blood glucose level. Successful induction of diabetes was defined as blood glucose > 14.6 mmol/L. Mechanical paw withdrawal threshold to yon Frey stimuli (MWT) and paw withdrawal latency to thermal nociceptive stimulus (TWL) were measured 2 d before and 14 d after IP streptesocin and on the 1, 3, 7, 14 d of curcumin administration. Animals with pain threshold measured at 14 d after IP streptozocin decreasing by less than 15% of the baseline were excluded from the study. The animals were sacrificed after the last pain threshold measurement and the lumbar segment of the spinal cord and p65 was significantly higher in group D than in group C ( P < 0.05). Curcumin administration significantly reduced thermal and mechanical hyperalgesia induced by diabetes and down-regulated the expression of p-JNK and horn and DRG.

Using recombinant TpNs proteins of Treponema pallidum as antigens, ELISAs are proved to be of higher sensitivity and specificity. However, they can be further increased by using multiple TpNs antigens. According to the epitope analysis, we firstly used linking primers PCRs to obtain an artificial fusion gene segment tpE17-47 containing epitopes of both TpN17 and TpN47. Subsequently, we conducted the prokaryotic expression systems of entire tpN17 and tpN47 genes and tpE17-47 fusion gene. SDS-PAGE analysis and BioRad Gel Image Analysis System showed that the recombinant proteins rTpN17, rTpN47 and rTpE17-47 expressed stably, with 36%, 20% and 28% yields of total bacterial protein, respectively. After purified by Ni-NTA affinity chromatography, all the three recombinant proteins could be recognized by T. pallidum antibody positive sera from syphilis patients. The positive rate of rTpE17-47-ELISA for detecting serum specimens in clinically 630 cases with syphilis was 98.6%. This rate was slightly higher than that by Treponema pallidum particle agglutination (TPPA) (97.9%) (P > 0.05), but significantly higher than those by rTpN17-ELISA (83.8%), rTpN47-ELISA (83.3%) and rapid plasma reagin (RPR) (72.1%) (P < 0.01). Furthermore, both ELISAs and TPPA for detecting the serum specimens in 25 cases with SLE, 36 cases with RA and 250 healthy cases were all negative. RPR showed positive in 1 case with SLE, 2 cases with RA and 2 healthy cases. This could be a novel serological screening or diagnostic method of syphilis with advantages of quickness, convenience, safety, sensitivity and specificity.

Objective To develop an indicator system to evaluate nursing safety management in Neonatal Intensive Care Unit ( NICU ) . Methods To review relevant literature and relevant documents combined with nursing safety issues and expert interviews, we used to study out the preliminary nursing safety management evaluation indicators in NICU. Delphi method was used to screen indicators. After two rounds of surveys, the indicators were identified by Hierarchy analysis. Results A total of 17 experts completed two rounds of consultation. In two rounds of surveys, the rates of questionnaire retrieve were 91. 3% and 94. 4%, respectively. The authoritative coefficients were 0. 913 and 0. 919, and the coordination coefficients were 0. 995 and 0. 998 (P <0. 01). The indicator system was established, which included 4 first level-dimensions, 13 second level-dimensions and 57 third level-dimensions. Conclusions Nursing safety management evaluation indicator system in NICU is constructed. It can be used to standardize the nursing behavior, and to improve the nursing quality, to protect the safety of children and to provide reference for strategy of safety.
