Objective To explore the role of focus intervention mode in improving the self-efficacy and subjective well-being of newly-contracted nurses. Methods A total of 100 nurses selected as the survey subjects by means of convenient sampling method, were numbered consecutively and divided into observation group and control group by random digit number table. The observation group was intervened with conventional mental consultation and the observation group with the WeChat-based focus intervention mode, which included the use of past-oriented questions and answers for understanding their strength and sources, future-oriented presuppositions and miracle-oriented questions for their thinking of resolutions to future problems. The two groups were compared in terms of general self-efficacy and well-being by the general self-efficacy scale (GSES) and the overall well-being scale (GWB). Results Before intervention , the total scores on GSES and GWB of the observation groups were insignificantly higher than those of the control group (P > 0.05). After intervention, the scores of observation group were significantly higher than those in the control group (P < 0.01). Conclusion The We-Chat-based focus intervention mode can effectively improve the self-efficacy and subjective well-being of newly-contracted nurses.

Objective To investigate the triggering receptor expressed on myeloid cells-1(TREM-1) of cord blood leukocytes in neonates and the transcription level of mRNA, and analyze its promoting function of inflammatory cytokine secretion. Methods During the period from September 2013 to March 2014, cord blood was collected from 20 term neonates at the time of birth, and peripheral blood was collected from 20 healthy adults. The expression of TREM-1 and TREM-1 mRNA on leukocytes was observed using flow cytometry and real-time reverse transeription-polymerase chain reaction, respectively. After the whole cord blood was stimulated by lipopolysaccharide (LPS) or LP17 plus LPS, the contents of interleukin (IL)-6, tumor necrosis factor-α (TNF-α), IL-8 and soluble TREM-1 (sTREM-1) in the supernatant were analyzed by enzyme linked immunosorbent assay. The statistical significance was determined using the one-way ANOVA test, t test, q test and Pearson correlation coefficient. Results The mean fluorescence intensity of TREM-1 on leukocytes of newborns was not different compared with healthy adults (P>0.05), while the percentage of TREM-1 positive on polymorphonuclear cells was lower than that of healthy adults [(82.3±7.1)% vs (98.6±4.8)%, P<0.05]. The level of TREM-1 mRNA in newborns was lower than in healthy adults (1.16±0.13 vs 1.63±0.24, t=7.714, P<0.01). The LPS treatment significantly increased sTREM-1 in newborn whole blood compared with the control treatment [(156.7±36.3) vs (34.6±6.1) pg/ml, t=13.623, P<0.01]. The concentration of IL-6, TNF-αand IL-8 decreased significantly when TREM-1 was blocked by LP17. In addition, the concentration of sTREM-1 showed a positive correlation with the levels of TNF-α(r=0.519, P<0.05), IL-6 (r=0.507, P<0.05) and IL-8 (r=0.538, P<0.05). Conclusions Healthy newborns exhibit expression of TREM-1 on monocytes similar to healthy adults, and most PMNs express TREM-1 at the newborn stage. Blocking the TREM-1 signal transduction pathway may reduce inflammatory responses of neonate leukocytes.

Objective: To compare the effects of synthetic 2 ?(3 hydroxypropoxy) calcitriol(ED 71) with 17 ? Estrodiol(E 2) on bone mass, strength and metabolism in ovariectomized(OVX) mice. Methods: 40 female Kunming mice, average 35 g, were randomly divided into 4 groups: OVX group, Sham group, ED 71 group and E 2 group. The latter two groups were also ovariectomized and given ED 71 at 0.4 ?g/(kg?d) and E 2 at 30 ?g/(kg?d) respectively for 6 w. Bone mineral density(BMD), bone mineral content(BMC), bone strength and bone histomorphometric parameters were measured. Results: Compared with OVX mice, in ED 71 and E 2 group, femoral BMD and BMC increased respectively by 3.8%, 5.9% and 3.2%,5.7%; maximum load of femur increased respectively 18.7% and 16%; trabecular bone volume of lumbar vertebra increased respectively 10.6% and 16.1 and serum alkaline phosphatase decreased respectively by 58% and 37%. Conclusion: ED 71 significantly increased BMD, BMC and bone strengh and significantly inhibited bone turnover in OVX mice. Also ED 71 does not induce uterus proliferation.

Objective:To explore the characteristics of attention during visual search tasks in adults with attention-deficit/hyperactivity disorder (ADHD).Methods:Totally 45 adult patients with ADHD who met the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-IV) and 44 healthy controls matched with age,gender and IQ were selected.The reaction time and accuracy rate of two groups were compared under visual search tasks of low and high visual working memory load.Results:The reaction time was longer in patients with ADHD than in the healthy controls in both low-load task [(823 ± 144) ms vs.(754 ± 123) ms,P ＜ 0.01] and highload task [(912 ± 163) ms vs.(851 ± 162) ms,P ＜ 0.01].Compared with the performance in low load task,the search reaction time was longer in high load task [ADHD group:(823 ± 144) ms vs.(912 ± 163) ms,P ＜ 0.01;control group:(754 ± 123) ms vs.(851 ± 162) ms,P ＜0.01] and the accuracy rate was lower during high load task than low load task[ADHD group:(95.9 ±4.3)％ vs.(91.2 ± 14.29)％;control group:(95.8 ± 4.2)％ vs.(94.4 ±4.9) ％,P ＜ 0.01] in both ADHD and control groups.Conclusion:The results suggest impairment in top-down attentional control in ADHD adults.When the visual working memory load is increasing,ADHD patients allocate more working memory resources on storing the target representation and less resources on visual attention,so the search efficiency may be influenced.

Objective To investegate the effect of ginsenoside Rg1 on the apoptosis related protein FLICE-inhibitory protein(FLIP),Fas-associated death domain protein (FADD)and Caspase-3 in the subatania nigra(SN)of 1-methyl-4-phenyl-1,2,3,6-tetrahyd-ropyridine (MPTP)-induced mouse models of Parkinson’s disease(PD), and to investigate the role of FADD and FLIP in the pathogenesis of PD and the protective effect of ginsenosides Rg1 on dopaminergic neurons.Methods 45 C57BL/6N mice were randomly divided into control group,model group and ginsenoside Rg1 group (n=15).The mice in model group were injected with MPTP by intraperitoneal,the mice in Rg1 group were injected with ginsenoside Rg1 before injecting MPTP,and the mice in control group were injected with normal saline by intraperitoneal. The behavioral changes of the mice in various groups were observed, and immunohistochemistry and Western blotting methods were used to observe the expressions of tyrosine hydroxylase (TH),FADD,FLIP and Caspase-3 in substantia nigra of the mice.Results Compared with control group,the mice in model group presented with typical symptoms of PD, the TH-positive neurons in the subatania nigra was significantly reduced (P<0.01 ), the number of FADD, FLIP and Caspase-3 positive cells was significantly increased(P<0.01),and the cytoplasm was deeply stained;the protein expression levels of FADD,FLIP and Caspase-3 were significantly increased (P<0.01).Compared with model group,the PD symptoms of the mice in ginsenoside Rg1 group reduced, the number of TH-positive neurons was significantly increased, the number of positive cells of FLIP,FADD and Caspase-3 were significantly reduced(P<0.01),and the cytoplasm was lightly stained;the protein expression levels of FADD, FLIP and Caspase-3 were significantly reduced (P<0.01 ). Nonlinear correlation analysis found that there was a positive relationship between the number of FADD and Caspase-3 positive cells (r=0.791,P<0.05).Conclusion Ginsenoside Rg1 may play a neural protective effect dopaminergic on neurons by modulating the FADD and FLIP expressions in SN of PD model mice.

Objective To study the radiological manifestation of Tolosa-Hunt syndrome,and to provide image basis for its clinical diagnosis.Methods Twelve cases with clinically diagnosed Tolosa-Hunt syndrome from 1994 to 2002 were retrospectively studied,and CT,pre- and post-contrast MRI,DSA,and MRA were analyzed.Results The appearances in 7 of the 12 cases were positive,while the other 5 cases showed negative findings.The positive appearances included the enlargement of one side of cavernous sinus and the mass at the orbit tip,which presented soft tissue density on CT images,isointensity or slight hypointensity on T_1-weighted images and slight hypointensity,hyperintensity or isointensity on T_2-weighted images.This abnormal tissue markedly increased in density or signal intensity on enhanced CT or MRI,associated with enhancement of adjacent dura mater.Conclusion There is some abnormal radiological appearance in some cases of Tolosa-Hunt syndrome.CT and MRI present important value for the diagnosis.
