Objective To give a systematic reviews on effect of taking blood gas via cephalic artery for infants.Methods Meta-analysis were used to analyze literatures about taking blood gas via cephalic artery for infants.Results 11 studies were included.The rate of successful puncture was 87.5％～98.0％ in the intervention group and 55.3％ ～94.6％ in the control group.The rate of successful puncture via cephalic artery were higher.Conclusions Effect of taking blood gas via cephalic artery for infant was better than that via other artery.Successful rate was high,while the incidence rate of local side effects was low.

Language is an unique complex psychological activity of human beings.Language barrier is a decline of effective activities and interactions in supporting the cognitive process of language behavior.Cognitive function is affected to a certain degree in patients with post-stroke aphasia.Therefore,accurately identifying these cognitive impairments contribute to the treatment and rehabilitation of the patients with aphasia.The assessment of the severity of cognitive impairment needs to use the cognitive assessment scales.This article reviews the cognitive assessment scales that are applicable for patients with post-stroke aphasia.

ObjectiveTo study the effects of intermittent subglottic secretion drainage(SSD)with an endotracheal tube on incidience of ventilator- associated pneumonia(VAP). MethodsWe searched computerized databases,including Cochrane library,Pubmed,EMbase,CBM,CNKI,Wanfang and some relevant databases from initializing to March 2012,extracting data about subglottic secretion drainage(SSD)with an endotracheal tube on incidence of VAP using RCT.The data had Meta- analysis by software RevMan5,and to those data which could not be conversed or merged,they underwent descriptive analysis. ResultsWeidentifled 5 randomized clinical trials that met the inclusion criteria with a total of 683 randomized patients.In Meta- analysis,the overall risk ratio for ventilator- associated pneumonia was decreased significantly by intermittent subglottic secretion drainage with an endotracheal tube.There was no significant difference on adverse events or on hospital or intensive care unit mortality.Databases,including ICU and hospital LOS,duration of endotracheal catheterization,bacteria concentration,which were difficult to be conversed and obtained full data,they underwent a descriptive research. ConclusionsCompared with the common endotracheal tubes,the use of endotracheal tubes with subglottic secretion drainage is effective for prevention of ventilatorassociated pneumonia.But it has no effect on adverse events or on hospital or intensive care unit mortality.So large sample RCTs with multiply- center should be carried out to assess the effect of the use of SSD.

ObjectiveTo explore the effects and significance of acetazolamide on the expression of aquaporin-4(AQP4) of gastric mucosal in rats with endotoxemia. Methods30 SD rats were randomly divided into 3 groups: Sham operated control group( Control group) ,endotoxemia group( EDT group) and acetazolamide group( ATL group).The immunohistochemistry was used to assess the expression of the AQP4 in the gastric mucosal tissues. The serum tumor necrosis factor-α(TNF-α) and interleukin-1 β(IL-1β) levels in each group were measured by radioimmunoassay. ResultsThe expression of AQP4 and the levels of serum TNF-αt and IL-1 ββ in EDT group were higher than those in control group( P ＜ 0.01 ). After the ALT treatment, the expression of AQP4 and the levels of serum TNF-α and IL1 β in ALT group were lower than those in EDT group( all P ＜0.01 ) and the expression of AQP4 in the gastric mucosal tissues in ALT group was also lower than those in EDT group( P ＜0.01 ). ConclusionThe raising of AQP4 expression and increasing of serum TNF-α, IL-1β take part in the progress of gastric mucosal injury in rats with endotoxemia. ALT could protect the gastric mucosal tissues by lowering the AQP4 expression and reducing the levels of serum TNF-α and IL-l β.

Objective To obtain and identify dendritic cell (DC) from mouse bone marrow in vitro. Methods Recombinant mouse granulocyte and macrophage colony stimulus factor (GM-CSF) induction was used to induce mouse bone marrow cells to form dendritic cells in vitro. The morphological changes were observed with light inverted microscope and scanning electron microscope (SEM). CD11c, MHCⅡ, and CD86 were identified with flow cytometry. The biological function was studied with antigen phagocytosis test and mixed lymphocyte reaction (MLR). Result The cultured DC from mouse bone marrow displayed the typical morphological characteristics of DC. Immature DC, which had high expression in CD11c and low expression in MHCⅡ and CD86, could phagocytize antigen. Mature DC, which had high expression in CD11c, MHCⅡ and CD86, could stimulate allogenic mixed lymphocyte proliferation. Conclusion DC can be generated from mouse bone marrow cells through cytokine induction in vitro and be used for further study associated with DC.

Objective:To assess the clinical and microbiologic effects of ultrasonic scaling with simultanous irrigation with chlorhexidine(CHX), conventional ultrasonic scaling or subgingival irrigation. Methods: 20 teeth in 7 patients with periodontitis were equally divided into test and control group. Patients in the test group were treated by irrigation with CHX during ultrasonic scaling(Master400),those in the control with irrigating after scaling(MiNi ). Clinical assessments of bleeding on probing (BOP),probing depth (PD) were made just before and 7 and 14 days after treatment. The subgingival microbiologic examination was performed before and 0,7 and 14 days after treatment. Result: Significant reductions in PD and BOP were observed in both groups 7 and 14 days after treatment(P

Objective To observe the effect of Xingding injection on renal fuction,blood Laminin(LN)and Collegen Ⅳ(C-Ⅳ)in chronic renal failure(CRF).Methods Effect of SerumCreatinine(SCR),BloodUreaNitrogen (BUN)、Hemoglobin(Hb)、ALT、24 hupq、Laminin(LN)、Collegen Ⅳ(C-Ⅳ)was observed in CRF pa- tients.Results Compared with the controlvalues,significantly decreased the level of Scr,BUN,LN,C-Ⅳ and 24 hupq(P

Objective To describe the status and analyze the influencing factors of nurses' compassion fatigue and compassion satisfaction in a certain tertiary hospital,which may provide evidences for the emotional management of nurses by nursing managers.Methods A cross-sectional survey was used in this study and 246 nurses were recruited totally.They investigated about compassion fatigue and compassion satisfaction by questionnaires.Results The average score of nurses' compassion fatigue was (30.76± 5.61)points.The average score of nurses' compassion satisfaction was (25.68±4.12)points.There was a significant difference for nurses' compassion fatigue in various wards,and ICU nurses had the top score.There were no significant differences for nurses' compassion satisfaction.Conclusions The nurses' compassion fatigue and compassion satisfaction in this hospital was relatively moderate.ICU nurses' compassion fatigue score was higher than other wards.Education background,professional title,relationship with colleagues,extra work,support from leaders and family members,wards,education background and relationship with colleagues were the influencing factors of nurses' compassion satisfaction score.

Objective To explore the surgical treatment effect of hyperthyroidism.Methods The clinical datas of 508 hyperthyroidism patient operation cure were reviewed.Results 2 cases had hypothyroidsim,no signs indicated injuries of superior laryngeal nerve and recurrent laryngeal,no recurrence of hyperthyroidism,no one died.Conclusion The thyroidectomy is the best treatment for the hyperthyroidism.Sufficient prepare before operation can reduce complications.
