Objective In order to provide best nursing services to transfusion patients in OPD, demands of transfusion patients in OPD and cognition of nurses to these demands were investigated. Methods By us-ing self- designed questionnaires which were modified and evaluated by specialists. Its coefficients of relia-bility and validity were above 0.91. Information about demands of transfusion patients in OPD and cognition of nurses to these demands were gathered and statistically analyzed. Results The investigation results showed that demands of patients in OPD were much higher than nurses' perceptibility. And there were dif-ferences among all kinds of patients. Conclusions Transfusion patients in OPD need better services. There exists differences between demands of patients and cognition of nurses to these demands. In order to give better nursing services, nurses should give intensive care to patients on safe, love and home, respect and self- actualization.

Objective To investigate the clinical value of amplitude integrated electroencephalogram on early diagnosis and prognosis evaluation of brain injury caused by neonatal asphyxia.Methods A total of 34 full-term asphyxiated neonates(asphyxia group)hospitalized in NICU of our hospital from January 2015 to September 2015 were selected;meanwhile,34 full-term healthy infants(control group)of the same term were selected.All cases were monitored for the activities of aEEG background,sleep-awakening cycle(SWC)and epileptic activity(SA)within 6 hours after birth.Meanwhile,the relationships between various indexes and asphyxia degree and brain injury were analyzed.Results The electroencephalogram of the asphyxia group was 52.9％and the rate of SWC was 58.8％,which were lower than those of the control group,and the difference had statistic significance(P<0.05).Meanwhile,neonates with epileptic activity in asphyxia group accounted for 11.8％,which was higher than that of control group significantly(P<0.05).Conclusion The AEEG changes of neonates at early period after birth are closely related to perinatal asphyxia and brain injury after asphyxia.The application of amplitude integrated electroencephalogram has an important significance on early diagnosis of neonatal asphyxia.

Objective To investigate subtle structural changes of white matter in patients with amnestic mild cognitive impair-ment (aMCI)using a tractography-based method.Methods Thirty patients with clinical diagnosis of aMCI and thirty-one cases of normal control(NC)and undergone diffusion tensor imaging.Cingulum (CG),corpus callosum (CC),uncinate fasciculus (UNC) and inferior occipitofrontal fasciculus (IOFF)were reconstructed,and fractional anisotrophy (FA)values were measured along these tracts using dTV II software.Differences of white matter tracts’FA values were explored between aMCI group and NC group.In addition,correlation analyses were also done between FA values and the MMSE(mini-mental state examination)scores in the aMCI patients.Results ① aMCI patients exhibited significant lower FA values in the bilateral CG,bilateral UNC and CC than NC group. Although there were no statistically significant differences,aMCI patients exhibited lower FA values than NC group in the left IOFF.② The FA values of right CG were positively correlated with MMSE scores.Conclusion Abnormal changes of FA values in CG,UNC and CC of aMCI patients suggest that subtle damages of white matter tracts related to memory exist in the prodromal phase of Alzheimer’s disease (AD).Fiber tractography has high sensitivity in detecting early damages of white matter.

Objective To explore the effect of in utero exposure to inlfammation on innate immune response in preterm infants. Methods Forty-seven premature infants with gestational age<35 weeks were recruited in this study. According to his-tological evidence of placental infection, all neonates were divided into intrauterine inlfammation positive group and negative group. Mononuclear cells and monocytes were isolated from umbilical cord blood, and were cultured in vitro in the presence or absence of LPS (100 ng/ml). The levels of interleukin 1β(IL-1β), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and interleukin 10 (IL-10) in cord blood plasma and monocyte cultural supernatants were measured by ELISA respectively. The level of IL-1β, TNF-α, IL-6 and IL-10 mRNA were detected by Real-time PCR. Expression of HLA-DR on surface of CD14+monocytes and ratio of CD3+CD4+/CD3+CD8+T was analyzed by lfow cytometry. Results (1) The level of cord plasma IL-6 in intrauterine inlfammation positive group was signiifcantly higher than in negative group. (P=0.02). (2) After stimulation of LPS, levels of IL-1β, IL-6, TNF-α, IL-10 in supernatants were increased signiifcantly, in consistence with their mRNA expression (P<0.05) in both groups. (3) Expression of HLA-DR on surface of monocytes was signiifcantly decreased after stimulation with LPS in intrauterine inlfammation positive group (P=0.012), but was signiifcantly increased in negative group (P=0.0305). Con-clusions In utero exposure to inlfammation does not suppress the response of monocytes to LPS in preterm neonates, but impairs the antigen presenting function in monocytes.

Objective To investigate the role of phosphorylated extracellular signal-regulated kinase (p-ERK), mitogen-activated protein kinase (MAPK)/ERK kinase (MEK), and nuclear factor-κB (NF-κB) in the pathogenesis of psoriasis vulgaris. Methods Immunohistochemistry and Western blot were used to detect the expression of p-MEK, p-ERK and p-NF-KB in tissue samples from 30 patients with psoriasis vulgaris and 15 normal human controls. The average optical density of immunostaining and relative grey scale of immuno-bloting were calculated. Results The average optical density of immunostaining for p-MEK, p-ERK and p-NF-KB was 0.36 ± 0.03, 0.36 ± 0.04 and 0.26 ± 0.04, respectively in lesion samples of psoriasis, significantly higher than that in normal control tissue (0.22 ± 0.02, 0.18 ± 0.03 and 0.16 ± 0.03, all P < 0.01). A significant increase was also observed in the relative grey scale of p-MEK, p-ERK and p-NF-κB in psoriatic lesions compared with the normal controls (1.41 ± 0.14 vs 0.54 ± 0.10, 2.35 ± 0.34 vs 1.86 ± 0.12, 1.07 ± 0.15 vs 0.87 ± 0.08, all P < 0.01). Conclusions The expressions of p-MEK, p-ERK and p-NF-κB are enhanced in lesions of psoriasis vulgaris, and the abnormal activation of upstream and downstream molecules in the MAPK signaling pathways might be involved in the pathogenesis of psoriasis.

Objectives: To investigate whether the protective actions of ginsenoside Rb1 (Rb1) on astrocytes are mediated through the Gs-type G-protein-coupled receptor (GPCR-Gs). Methods: Primary astrocyte cultures derived from neonatal mouse brain were used. Astrocyte injury was induced via oxygen-glucose deprivation/re-oxygenation (OGD/R). Cell morphology, viability, lactate dehydrogenase (LDH) leakage, apoptosis, glutamate uptake, and brain-derived neurotrophic factor (BDNF) secretion were assessed to gauge cell survival and functionality. Western blot was used to investigate the cyclic adenosine monophosphate (cAMP) and protein kinase B (Akt) signaling pathways. GPCR-Gs-specific inhibitors and molecular docking were used to identify target receptors. Results: Rb1 at concentrations ranging from 0.8 to 5 μM did not significantly affect the viability, glutamate uptake, or BDNF secretion in normal astrocytes. OGD/R reduced astrocyte viability, increasing their LDH leakage and apoptosis rate. It also decreased glutamate uptake and BDNF secretion by these cells. Rb1 had protective effects of astrocytes challenged by OGD/R, by improving viability, reducing apoptosis, and enhancing glutamate uptake and BDNF secretion. Additionally, Rb1 activated the cAMP and Akt pathways in these cells. When the GPCR-Gs inhibitor NF449 was introduced, the protective effects of Rb1 completely disappeared, and its activation of cAMP and Akt signaling pathways was significantly inhibited. Conclusion Rb1 protects against astrocytes from OGD/R-induced injury through GPCR-Gs mediation.

Objective To explore the impact of psychological intervention on the mental state of related donors for allogeneic hematopoietic stem-cell transplantation(HSCT). Methods 64 donors for HSCT were randomly divided into intervention and control groups (32 cases for each group). Routine preoperative health education was given to the donors in the control group and psychological intervention was adopted in the intervention group on the basis of routine health education. Zung self-rating depression scale (SDS) and self-rating anxiety scale (SAS)were used to mark the scores of the mental state of donors in both groups and heart rate, blood pressure of the donors were recorded and analyzed before and after intervention. Results Compared with those before intervention, there were no statistically significant differences in blood pressure and heart rate of the donors in the intervention group (P ＞ 0. 05); the differences were statistically significant in the comparison of blood pressure and heart rate of the donors between the two groups (P ＜ 0. 05). The scores of depression and anxiety decreased compared with those before intervention in the intervention group (P ＜ 0. 05), and the differences in the comparison of the scores were statistically significant between the two groups (P ＜ 0. 05). Conclusions Psychological intervention is the key to reduce anxiety and depression and stabilize blood pressure and heart rate of the related donors for allogeneic hematopoietic stem-cell transplantation.

OBJECTIVETo observe the effectiveness and safety of external applying Compound Tripterygium wilfordii Hook F. (TwHF) in relieving joint pain in rheumatoid arthritis (RA) patients.

METHODSIn this double-blinded, randomized multicenter trial, a total of 174 moderately active RA patients were enrolled and randomly assigned to the treatment group (treated with Compound TwHF, 87 cases) and the placebo control group (87 cases). Compound TwHF or placebo was externally applied in painful joints, 20 g each time, once per day for 8 weeks. Self-reported joint pain relief was taken as a primary effective indicator. Visual analogue scale for pain (VAS), disease activity score of 28 joints (DAS28), VAS for general health (GH) were evaluated before treatment, at week 4 and after treatment. Erythrocyte sedimentation rate (ESR) and hypersensitive C reactive protein (hs-CRP) were tested before and after treatment. Menstrual changes in females were observed during treatment. Skin irritation occurred during the recording process was assessed using skin irritation strength. Intention to treat (ITT) was statistically analyzed.

RESULTSThe joint pain relief rate in the treatment group was 90.8% (79/87 cases), higher than that in the placebo control group (69.0%, 60/87 cases; P = 0.001). VAS pain score, DAS28, VAS for GH score were significantly improved in the two groups at week 4 of treatment and after treatment, as compared with before treatment (P < 0.01). ESR and hs-CRP levels significantly decreased in the treatment group after treatment (P < 0.05, P < 0.01). No difference was found in post-treatment VAS pain score, DAS28, VAS for GH score, ESR, or hs-CRP between the two groups (P > 0.05). Eight adverse events occurred in the treatment group (5 skin allergy, 1 intolerance of medical odor, and 2 mild liver injury), while 3 adverse events occurred in the placebo control group (2 skin allergy, 1 mild liver injury). There was no statistical difference in adverse event between the two groups (P > 0.05). No menstrual change occurred in the treatment group.

CONCLUSIONExternal applying Compound TwHF was an effective and safe way to relieve-joint pain of RA patients, which could be taken as an adjuvant therapy.
