The field of rehabilitation medicine physical therapist (PT) training and education has been relatively weak links in China, how to build a rehabilitation therapist team, we constantly explore and get a greater progress. However, most of the time is still confined to empty the contents of most theoretical level, and some basic steps and the specific contents are lacked. How to stabilize therapists team? How to position therapists? It deserves to pay more attentions.

Objective Using Doppler ultrasound measured in femoral artery flow velocity variation rate method to predict fluid responsiveness.Methods 80 patients were measured femoral artery flow velocity variation rate (△Vpeak)by mastering the ultrasound skills of the attending physician.Passive leg raising test (PLR)stroke vol-ume variation (△SV)was used to analyze the peak value of the femoral artery flow velocity,rate of femoral artery peak velocity of respiratory changes,and the results were compared with results of PICCO monitoring to predict patients with their response to the treatment capacity,to evaluate clinical feasibility.Results Reactive groups in the PLR test before the experiment and hemodynamic changes:PLR test reaction group in before the test and test process, HR,MAP,CAP index changes were not obvious (P >0.05),but ultrasonic detection and PICCO detection showed SV and CO varied significantly (t =15.24,P =0.00;t =13.64,P =0.00),the two kinds of methods to forecast results was consistent.In the absence of the anti should patients in PLR test before the experiment and hemodynamic chan-ges:PLR test unreacted group in before the test and test process,HR,MAP,CAP,SV and CO index change were not obvious (all P >0.05).Conclusion By ultrasonic method for measuring femoral artery flow speed variation rate can exactly evaluate the capacity status of critically ill patients,and effectively predict fluid responsiveness,the prediction results and PICOO monitoring results are highly consistent.It is a safe and efficient prediction method,which is worthy of promotion in clinical intensive observation.

Translational medicine is a novel concept about combination of basic research and clinical application. The aim of translational medicine is to realize the translation of basic research into clinical practice. microRNAs (miRNAs) are non-coding single-stranded RNAs with 21-25 nucleotides in length as newly discovered factors in regulating gene expression. Recently, the key regulatory role of miRNA in the cardiovascular system has been elucidated and amount of remarkable results has been achieved, particularly in the regulation of cardiac arrhythmias. A series of studies demonstrate that miRNAs are involved in the regulation of expression of a variety of proteins associated with cardiac electrical activity, and are the potential targets of occurrence of cardiac arrhythmias and anti-arrhythmic drugs. miRNAs as a therapeutic target regulate the stability of mRNAs of target genes or play an inhibitory role in the translation process. Stability of the corresponding miRNA expression levels in the target organ may be a new approach for the disease therapy. Regarding the dysfunction of miRNA, we employed miRNA re-expression strategy and anti-miRNA strategy to correct target protein function and provide a new entry for the therapy of arrhythmia. With the technology of miRNA mimics and antagomirs, miRNAs are expected to treat various cardiovascular diseases and will provide a fresh impetus to achieve transform medicine.

[Objective]To evaluate the method and curative effect of posterior internal fixation and bone grafting fusion for atlantoaxial fracture or dislocation.[Method]Posterior internal fixation and bone grafting fusion were made on 26 patients with atlantoaxial fracture or dislocation in condition of tracheal intubation anesthesia.Occipitocervieal fixation(Aixs) and bone grafting fusion were performed on patients with fracture of vertebral lamina-arch.Vertebral lamina splint fixation (Apofix) was performed on patients without fracture of vertebral lamina-arch and decompression of vertebral canal.[Result]Followed up for 5 to 60 months(averaged,16.8 months),the vertebral artery and spinal cord injury were not occurred and clinical symptom was relieved in all patients.X ray examination showed screws in vertebral articular process and occipital condyle were normotopic without laxation and fragmentation.The bone grafting transformed into osseous fusion after 3 months.[Conclusion]Aixs fixation and bone grafting fusion and Apofix fixation are effective methods for atlantoaxial fracture or dislocation.

Objective To investigate the combination effect of curcumin and γ-ray irradiation on PANC-1 cells in vitro.Methods PANC-1 cells were exposed to γ-rays in the presence or absence of curcumin.MTT assay was performed to evaluate cell viability.The expression of P21 was evaluated with RT-PCR and Western blot.Cell cycle distribution and apoptosis were tested by flow cytometry.Results Compared with the γ-ray irradiation group,combination treatment of curcumin and irradiation decreased the cell viability (t =6.72,P ＜ 0.01) and increased the percentage of cells in S-phase (t =4.78,P ＜ 0.05),apoptosis rate (t =6.58,P ＜ 0.01),P21 protein and mRNA expression (t =5.72,5.63,P ＜ 0.01) in PANC-1 cells.Conclusions Curcumin increases the radiosensitivity of PANC-1 cells,which may have clinical implication on radiotherapy of pancreatic cancer.

Objective To investigate the status quo of transformational leadership,psychological empowerment,team psychological safety and team effectiveness,and test whether the supposed structural equation is tenable.Methods Totally 380 nurses completed the Transformational Leadership Questionnaire,Psychological Empowerment Questionnaire,Team Psychological Safety Questionnaire and Team Effectiveness Questionnaire,structural equation model was used to verify the relationship of the above,Bootstrapping confidential interval and product of coefficient were used to test the mediating effect.Results Significant correlations were found between transformational leadership,psychological empowerment,team psychological safety and team effectiveness (P ＜ 0.01),transformational leadership played indirect effect on team effectiveness (Z=6.195,P ＜ 0.05),psychological empowerment and psychological safety had a totally mediation effect.Conclusions Healthcare workers should make psychological empowerment and team psychological safety as the breakthrough point,fully play the advantages of transformational leadership on team effectiveness in order to increase the working ability of nurses and make them complete the clinical work effectively and with high quality.

The morbidity of diabetes has been increasing rapidly in recent years. Delayed wound healing has become a common complication in diabetes, which seriously affects the orthobiosis of patients. Exploring and finding the molecular mechanisms of diabetic wound healing and the effective therapies to promote wound healing have important clinical significances. Stem cells transplant has become a research hotspot in accelerating diabetic wound healing. This article reviewed the present approaches concerning stem cells transplant in diabetic wound healing both at domestic and abroad, and looked forward the clinical therapy of stem cells on diabetic wound healing.
