Objective To explore the effect of high quality nursing care performing in the operating room and reasonable approach for assessment. Methods Stratified random sampling was used to select 93 nurses from two tertiary hospitals. The task performance and contextual performance was assessed before and after implementing a range of high quality nursing care program. Results The task performance scores and patient care, nursing information, nurse skills dimension scores respectively were 58.59 ±1.77, 19.27±1.16, 19.50±1.11, 19.80±0.70 after the operating room junior high quality nursing service project, which were 37.21 ± 1.92, 5.55 ± 0.86, 13.78 ± 1.12, 17.87 ± 0.98 before the implementation, the differences were statistically significant (t=-82.48--15.15, P<0.01). The performance scores and mutual support between colleagues, work out the extra burden, organizational support dimension scores were respectively 70.43 ± 2.94, 28.23 ± 1.21, 18.52 ± 1.29, 23.67 ± 1.86 after the operating room junior high quality nursing service project, which were 36.20 ± 1.79, 15.52 ± 1.94, 7.33 ± 1.11, 13.34 ± 0.87 before the implementation, the differences were statistically significant (t=-91.99--46.68, P<0.01). Conclusions The high quality nursing care program is a range of nursing service which can advance task performance and contextual performance of nurses in the operating room. Task performance and contextual performance are effective approaches by which high quality nursing care in operating room could be reasonably assessed.

A 1-year-old boy developed multiple skin-colored nodules on the forehead and extremities when he was 4 months old.Physical examination revealed that his general condition was well with no hepatomegaly,splenomegaly,lymphadenectasis,testicle abnormality or gingival hypertrophy.Pathologically,the epidermis was normal,while the dermis and subcutaneous tissue were diffusely infiltrated with medium-to large-sized deformed cells,which had a small amount of cytoplasm,oval nucleus,irregular shape and fine chromatin.Some infiltrating cells had nuclear groove and nucleoli.Immunohistochemical studies showed that the tumor cells were positive for S-100 protein,CD56,CD123,CD163,CD68,Ki-67 (40％),weakly positive for CD4 (some),but negative for myeloperoxidase,CD1,CD21.Bone marrow smears showed a 24.5％ infltration by monoblasts and promonocytes.A diagnosis of monoblastic sarcoma cutis preceding acute monoblastic leukemia was made.

Objective To investigate the effect of irrigation with hypothermic artificial cerebral-spinal fluid (aCSF)on expression of aquaporin-4(AQP-4) in the spinal cord following spinal ischemia-reperfusion (I/R) in rabbits.Methods Fifty-four adult male New Zealand white rabbits weighing 2.0-2.5 kg were randomly divided into 3 groups (n=18 each):group sham operation(S group); group I/R and group irrigation with hypothermic aCSF (FI group). Spinal I/R was induced by clamping the abdominal aorta below renal artery for 60 min. Hypothermic aCSF(25 X.)was infused at L4,5 interspace at a rate of 30 ml/h and drained from L7,8 interspace during spinal ischemia.Neurological function was evaluated at 4, 24, 48 and 72 h of reperfusion and scored (0=no hind limb activity, 4=hind limb function completely recovered) in 6 animals in each group. Six animals were sacrificed at 4, 24 and 72 h respectively in each group.The lumbar segment (L5-8) was removed for measurement of water content and AQP-4 protein expression (by immuno-histochemistry).Results Neurological function scores were significantly lower,water content was higher and AQP-4 expression smaller in group I/R than in group S. I/R-induced effects were significantly attenuated by irrigation of hypothermic aCSF. Conclusion Irrigation with hypothermic aCSF can ameliorate the spinal cord I/R injuries by up-regulation of AQP-4 expression.

Objective:To investigate parents′ knowledge and attitude toward post-operative pain management in pediatric orthopedics and analyze influencing factors.Methods:A total of 170 parents of 6 to 16 years old children who underwent selective surgeries and were hospitalized because of limb fracture were conveniently selected in Children′s Hospital of Soochow University from April to December in 2019, They were investigated using the general data questionnaire, Pain Management Knowledge and Attitudes Questionnaire.Results:There were 167 parents completed questionnaires in our study. The mean score of parents′ knowledge, general attitude and negative attitude to pain medication were 15.0(3.00), 24.0(4.00) and 17.0(3.00) respectively. There were statistical differences between different educational levels of parents′ knowledge ( χ2 value was11.599, P=0.021), as well as different age of parent′s general attitude ( χ2 value was 7.053, P=0.029). Spearman-related results showed that parents′ cognition was positively correlated with general attitudes ( r value was 0.394, P<0.01). Conclusions:The majority of parents are at moderate to high level of knowledge, general attitude and negative attitude to pain medication. Pediatric nurses should pay more attention to parents′ knowledge deficit of and negative attitude toward pain assessment tools and pain-drugs to develop targeted educational intervention programs for promoting parental involvement.

Objective To sum up the specificity in clinical care of repetitive transcranial magnetic stimulation (rTMS),and provide reference for putting forward scientific and effective clinical care project.Methods 200 male schizophrenia patients with rTMS treatment were divided into the research group and the control group with 100 cases in each group randomly.Then,the research group adopted the specific nursing which was obtained from the pre-experiment while the control group adopted the routine care.Moreover,NORS scale was used to evaluate the treatment effect.Changhai Pain Measuring Scale was employed to assess headaches in pre-treatment and post-treatment.Results The data of the research group in NORS scale was obviously lower than the control group,and the difference between two groups had statistical significance.No case occurred adverse reaction in the research group,in contract with many cases with adverse reaction in the control group.Conclusions Specific nursing can reduce complications effectively for schizophrenia patients receiving rTMS treatment,and it is a scientific,effective and mature clinical care method.

Objective To evaluate the effects of nurse-led team management on self-management and hyperten-sion control for community-dwelling hypertensive patients. Methods A quasi-experimental study design was adopt-ed,two communities were elected as the intervention group and the control group in Wuhou District,Chengdu,and 102 hypertensive patients were recruited from each group. The intervention group received nurse-led team manage-ment for 2 years,and intervention methods included individual management,phone or home follow-up,collective inter-vention and so on. While the control group received doctor-led hypertension management. The patients' self-man-agement behaviors and hypertension control were evaluated before the intervention and 6,12,24 months after the intervention. Results After 24-month nurse-led team management,scores of self-management behaviors and hyper-tension control rate of patients in the intervention group were significantly higher than those of patients in the con-trol group(P<0.05). Conclusion Nurse-led team management could significantly improve self-management behaviors and the rate of hypertension control for hypertensive patients.

Objective To study the injury and protective action of drugs on neurons, the model of glutamate excitotoxicity on primary cultured hippocampual neurons from new born rats were( set up. Methods)By use of trypan blue dye staning and testing the lactate dehydrogenase leakage from cultured neurons, to investigate the neuron survival rate. Results We found the injury of neurons was related with the concentration of glutamate. NMDAR non-competitive antagonist —MK-801 could protect the glutamate excitotoxic damage on neurons. Conclusion The glutamate results in neuron injury through NMDAR; the model of neuron culture was sufficient for glutamate-induced excitotoxicity.

The clinical data of 7 patients with porokeratosis (PK) were analyzed retrospectively.In 7 PK patients, 4 cases were disseminated superficial actinic porokeratosis (DSAP),1 case was disseminated superficial porokeratosis (DSP),1 case was giant porokeratosis (GP) and 1 case was hypertrophic porokeratosis (HP).The characteristic cutaneous manifestations were annular well-circumscribed keratotic plaques with slightly atrophic center and elevated border.All patients shared a common histological hallmark, the cornoid lamella.Four cases of DSAP patients had family medical history, consistent with autosomal dominant inheritance.DSP, GP and HP patients denied family medical history.Diagnosis of PK should be based on clinical manifestations, family medical history and histopathological examination.
