Objective To explore the effect of swimming and caressing on neonatal jaundice and weight.Methods Two hundred and forty newborns were divided equally into control and observation group with random digits table.The former received care with caressing and the latter with swimming and caressing.The two groups were compared in terms of weights and jaundice indices at birth and 7d after birth.Results Seven days after birth,the jaundice index in the observation group were lower than that of the control group and the weights of the observation group were larger(P<0.05).Conclusion Swimming and caressing are helpful for the development of neonates by C-sect and the reduction of jaundice duration.

Objective To figure out changes of serum excitatory amino acids (EAAs) levels in patients with amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD).Methods The levels of serum EAAs was assessed in 34 cognitively normal control subjects,30 patients with aMCI,and 32 patients with AD using high performance liquid chromatography (HPLC).Results ①Higher serum concentrations of glutamate((39.6?22.1) ?mol/L),alanine((282.5?71.3) ?mol/L) were found in the aMCI patients (P=0.044,P=0.007),and higher serum concentrations of glutamate ((42.2?21.8) ?mol/L),glycine ((464.2?142.6) ?moL/L) were found in the AD patients than in the control subjects (P=0.010,P=0.010).②No statistically significant difference of EAAs level between the aMCI and AD groups was found.③A close and positive correlation between the serum concentrations of glutamate, aspartate and the mini-mental status examination scores were found in AD patients:the 2 amino acid levels were higher in patients with mild dementia((42.1?21.3),(55.0?29.0) ?mol/L) than those with moderate or severe dementia ((25.4?9.2) ?mol/L,P=0.023;(34.6?11.1) ?mol/L,P=0.036). Conclusion EAAs,correlating with the severity of the condition,play a significant role in AD,while aMCI patients also have disturbance of metabolism of EAAs,indicating that it has similar pathogenesis to AD.

Objective: To investigate the effects of estrogen and progesterone on the expression of vascular endothelial growth factor (VEGF) and its receptors (VEGFR) in mouse uterus. Methods: 3-week-old immature female mice were randomly divided into 7 groups and treated with corn oil, estradiol (E2) of 1.5, 3.0, 10, 25 ng, progesterone (P) of 100 ?g and (E_2 10 ng + P 100 ?g)/mouse, respectively. After the treatment for 48 h, mouse uterus was collected to isolate total RNA. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expression of mRNA isoforms of VEGF and its receptors in mouse uterus. Results: Compared with control, both E_2 and P significantly increased the expression of VEGF164 and VEGF120 mRNA in mouse uterus. The expression of VEGFR2 mRNA, not VEGF1 mRNA, was decreased by E_2 treatment in a dose-independent manner. Conclusion: Both estradiol and progesterone up-regulated the expression of VEGF, but estradiol down-regulated the expression of VEGFR2 in mouse uterus.

Objective The present study was undertaken to investigate the properties of nonlinear dynamics of EEG and the changes in depth of anesthesia with real-time approximate entropy (ApEn) and complexity (Cx) nonlinear indexes monitoring during anesthesia. Methods EEG was recorded in 65 in-patients. They were randomly divided into 4 groups: isoflurane, sevoflurane, desflurane (n=15, respectively), and propofol intravenous anesthesia (n=20) groups. The EEG derived parameters ApEn and Cx non-linear indexes were calculated simultaneously during the whole operation including rest state with eyes closed, anesthetic induction, intraoperation, recovery, post-operation awaking. Results ApEn and Cx nonlinear indexes remained the highest during rest state. Both of them kept decreasing during anesthetic induction. They dropped to a relative lower value and leveled off in the intra-operation period. Both of them rose gradually during recovery period and returned to a high level in the post-operation awaking period (correspondingly, ApEn: 0.87, 0.78, 0.55, 0.64 and 0.83. Cx: 0.58, 0.54, 0.38, 0.46 and 0.57). Conclusions With ApEn and Cx non-linear indexes, changes in depth of anesthesia from EEG signal could be real-timely monitored and precisely measured. Nonlinear dynamic analysis might provide us with more information about consciousness and cognition during general anesthesia.

PurposeTo evaluate and describe fetal cardiac development and hemodynamics high risk pregnancy by using ultrasound technique. Methods Two-hundred and thirty-three pregnancies were prospectively studied by using the detailed fetal echocardiographic procedure( fetus gestational age from 19 weeks to 39 weeks). Cardiac chamber size, internal diameter of great arteries were documented together with the presence of inflow and outflow wave patterns. In utero diagnoses of variety of congenital heart defects were also conducted. ResultsCardiac chamber size and internal diameter of great arteries showed a positive correlation with the increasing of gestational age. Left and right ventricles were demonstrated the same size during whole fetal observational period. Blood flow through mitral valve and tricuspid valve were typically 'M' type. By comparing 'e' wave and 'a' wave, this inflow blood velocity pattern was dominant by 'a' wave, though the ratio of a/e gradually decreased during the fetal development period. Blood velocity in aorta and pulmonary artery remained steady along with the gestational age. The detection rate of verity types of congenital heart diseases in this sample population was 5.7% (13 cases) ,the major problem was the complex heart malformation. The occurrence of fetal cardiac arrhythmia was 14 cases (16 % ), with the majority of atrial premature beat. Conclusions Fetal echocardiography can be used to evaluate and monitor the change of cardiac anatomy, structure and hemodymanics during the different gestational age. This has provided a new approach to the further understanding of fetal cardiac development, and is importantto the screening of congenital heart disease during pregnancy.

Objective To investigate the effects of a miRNA family member, let-7e, and a combi-nation of miR-106b and miR-20a on the expression of cytokines by THP-1 cells with Luminex xMAP technol-ogy.Methods The efficiency of transfection was evaluated by immunofluorescence assay after transfecting THP-1 cells with micrONTM mimic negative control (Cy3) for 24 h, 36 h and 48 h.The three miRNA mim-ics (let-7e, miR-106b and miR-20a) were respectively used to transfect the THP-1 cells for 24 h, 36 h and 48 h and the expression of each miRNA was analyzed by qRT-PCR analysis for screening out the optimal transfection time.The transfected THP-1 cells were stimulated with1 mg/L of LPS for 1 h.The Luminex xMAP technology was used to detect the expression of IL-8, interferon-inducible protein-10 (IP-10), mono-cyte chemotactic protein 1 (MCP-1), IL-1α, IL-6, IL-10, TNF-α, IFN-αand IFN-βin the supernatants of cell culture.A statistical analysis was performed to analyze the data obtained by using SPSS16.0 software. Results More than 90% of the transfected THP-1 cells were labeled with red fluorescence.The optimal transfection times for let-7e mimic and miR-106b/miR-20a mimics were 48 h and 24 h, respectively.Com-pared with the corresponding negative control (NC), the expression of IL-8, IP-10 and MCP-1 by THP-1 cells were enhanced after the transfection with let-7e mimic, but were inhibited after the co-transfection with miR-106b and miR-20a mimics.Conclusion The expression of IL-8, IP-10 and MCP-1 were enhanced in let-7e transfected THP-1 cells, but were inhibited in miR-106b and miR-20a co-transfected THP-1 cells.

Objective To examine the relationship of coping style,psychological capital and vocational selection anxiety for female college graduates.Methods A sample of 330 female college graduates filled out measures for the simplified coping styles questionnaire (SCSQ),Psychological Capital Questionnaire (PCQ) and vocational selection anxiety Questionnaire(VSAQ).Results Correlation analysis showed that except the self-efficacy and positive coping style collected with concerns about job prospects was not significant (r=-0.08-0.05,P＞0.05),each dimensions of PCQ and SCSQ significantly correlated with the each dimensions of VSAQ (r=-0.44--0.13 or r=0.21-0.28,P＜0.01).Regression analysis showed that negative coping style,resilience,hope and positive coping style could directly predict vocational selection anxiety.Psychological capital were the mediators between positive coping styles and vocational selection anxiety.Conclusion Coping styles and psychological capital are closely related to the female college graduates' vocational selection anxiety,using appropriate coping styles and improving mental ability can effectively reduce vocational selection anxiety.

Objective To observe the effect of body-weight supported treadmill training (BWSTT) on the lower limb motor function of elderly hemiplegia patients with acute cerebral infarction using semi-quantitative analysis of regional cerebral blood flow (rCBF) through single photon emission computed tomography (SPECT). Methods Seven patients with cerebral infarction were given comprehensive rehabilitation therapy for 10 weeks in three stages: a baseline period of 2 weeks ( conventional rehabilitation therapy), an intervention period of 6 weeks ( conventional rehabilitation therapy plus BWSTT) and a withdrawal period of 2 weeks (conventional rehabilitation therapy). During the intervention period the exercise duration increased gradually from 15 to 30 minutes, once a day, 5 times a week,for 6 consecutive weeks. Dynamic changes in rCBF in the cortex were observed with SPECT before and after treat ment. Results During the baseline period there was no significant change in average MWS (maximum walking speed) or BBS ( Berg balance scale) scores. During the intervention period both scores improved significantly. During the withdrawal period there were some changes in MWS and BBS scores, but they were not significant. There was a significant change in average rCBF in the cortex after treatment compared with before. Conclusions BWSTT is effective for improving the walking speed and balance of elderly patients with acute cerebral infarction. There is a positive correlation between the recovery of lower limb motor function and changes in rCBF in the cortex.
