OBJECTIVE:To explore the use of antibiotics in the department of respiratory diseases and pediatric outpatient department after the introduction of initiative intervention stragety on the rational use.METHODS:A field investigation was carried out on the international RDU index of antibiotics in the department of respiratory diseases and pediatric outpatient department by self-control test.Initiative intervention on physicians' prescribing practices was carried out at four stages:befter intervention,following first intervention,second intervention,and third intervention,respectively.Data statistics was analyzed by SPSS11.0 software.RESULTS:The percentages of patients treated with antibiotics and injcetable antibiotics in the department of respiratory diseases dropped from 61.6% and 19.2% before intervention to 30.0% and 14.0% after third intervention(P

Objective To analyze the common causes leading to lung infection following renal transplantation and provide targeted preventive measures to reduce the incidence of lung infection.Methods The clinical data of 561 recipients who underwent renal transplantation from January 2006 to February 2011 were retrospectively analyzed.The recipients were divided into two groups:group Ⅰ,from January 2006 to December 2009 (n =416) ; group Ⅱ,from January 2010 to February 2011 (n =145).The causes possibly leading to lung infection which took place 3 days before the appearance of the clinical symptoms were offered by the patients who suffered lung infection of group Ⅰ.And then the causes were summarized and analyzed to formulate the specific and comprehensive measures to prevent the infection.Finally the measures were applied to recipients in group Ⅱ from January 2010.After applying the measures for 14 months,the incidence of lung infection in group Ⅱ was counted and compared with that in group Ⅰ to see the preventive effect.Results There were 58 cases of lung infection in group Ⅰ (58/416,13.9％) and 12 cases in group Ⅱ (12/145,8.3％). There was significant difference in the incidence of lung infection between two groups (x2 =4.0361,P＜0.05).All of the recipients with lung infection were hospitalized in six months after the transplantation.The causes leading to lung infection of 58 cases in group Ⅰ were as follows:6 cases due to being excessively tired,3 cases due to guest visiting,12 cases due to abrupt change of weather,9 cases due to exposure to public place,8 cases due to returning to hospital,6 cases due to close contact with children,5 cases due to close contact with animals,and the other 9 cases without specific causes found.Conclusion The incidence of lung infection following renal transplantation can be notably reduced by the application of targeted and concrete health propaganda education and preventive measures based on analysis on the specific causes of infection.

Objective:To investigate the ethical significance of the extracorporeal circulation membrane oxy-genation ( ECMO) in the donation organ transplantation .Methods: Analyzing the data of ECMO protected to the organ in 13 donors after brain death , Accounting the rising costs which caused by ECMO and make the interview to the patients and family members .Results:In the period of ECMO flow , the hemodynamic of the DBD donors be-come stable gradually , the medications reduced significantly or stop , the function of organs was restored .There were 38 organs can be used for the transplantation which were proven by the pathological biopsy .Twenty six kid-neys were transplanted to 26 recipients and liver transplantation was performed in 12 recipients.All transplantations were successfully completed .Medical cost of this patients increase 5.3%, all of the family members and patients can accept the intervention of ECMO .Conclusion:ECMO is an effective method to protect and improve the utili-zation rate of the organ .the improvement of the related technical standards , legal, laws and ethics of staff will pro-mote to the development of organ transplantation .

Objective To examine the benefits of ECMO for potential organ donors with hemodynamic instability after brain death.Methods Three brain-dead potential donors who presented with hemodynamic instability despite maximal medical management,finished a declaration of brain death,that were supported by extracorporeal circulation membrane oxygenation (ECMO).Results Donor organs,including six kidneys,and two livers,were harvested from the three donors under ECMO support,leading to 8 successful transplantations.The organs functioned well and the recipients made full recoveries.Conclusion Our experience indicates that ECMO allows for the maintenance of abdominal organ tissue perfusion without warm ischemia before organ procurement,providing sufficient time for safe organ donation procedures and reducing the risk of unpredictable cardiac arrest that could result in the donor death and graft loss.

At present, neuroimaging and neuroelectrophysiology are the main objective detection techniques of brain consciousness; and neuroimaging includes functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS). As a new non-invasive optical neuroimaging technology, fNIRS has more application prospects than fMRI: it can clear the cerebral cortex activation in resting state or different task states, such as real movement, motor imagination, or mental arithmetic; it can not only assess the consciousness horizontally, but also evaluate the effect of rehabilitation therapy vertically. In this paper, the application status of fNIRS in assessing consciousness of disorder is reviewed to explore new technical evaluation means for disorder of consciousness.

In aging society the development of non-invasive continuously blood pressure monitors which are suitable for homes, communities and nursing homes has a wide range of applications. This paper proposes a non-invasive continuously blood pressure monitoring based on wearable device which uses MSP430F5529 as the central processor. The design is divided into signal acquisition module, central control module, display module, power supply module and host computer module. The experimental results showed that DBP (375/390, 96.15%) and SBP estimation values (377/390, 96.67%) are in 95% confidence interval, which means our design passes Bland-Altman test with high accuracy and stability.

Objective: To explore the topological abnormality of brain metabolic network in patients with idiopathic rapid eye movement sleep behavior disorder (iRBD) and compare it with the topology of brain metabolic network in patients with Parkinson′s disease (PD). Methods: The ¹⁸F-fluorodeoxyglucose (FDG) PET brain images of 19 patients with iRBD diagnosed with polysomnography (PSG) (iRBD group; 15 males, 4 females, average age: 64.9 years), 19 patients with PD (PD group; 12 males, 7 females, average age: 62.2 years) and 19 gender and age-matched healthy controls (HC group; 15 males, 4 females, average age: 63.1 years) in Huashan Hospital from September 2014 to June 2015 were retrospectively analyzed. According to the complex brain network method based on graph theory, the brain metabolic networks of each group was constructed and the network parameters (clustering coefficient, characteristic path length, local efficiency, global efficiency and small-world property, etc) were evaluated quantitatively. The 500 times non-parametric permutation test was used to determine the differences in network parameters between groups. Results: The brain metabolic networks of iRBD group and PD group both had abnormal topological structure, which showed that the characteristic path length (for example, when sparsity=34%, HC vs iRBD vs PD groups: 1.517 vs 1.552 vs 1.561) and local efficiency (for example, when sparsity=30%, HC vs iRBD vs PD groups: 0.802 vs 0.824 vs 0.831) were significantly increased (both P<0.05), the global efficiency (for example, when sparsity=36%, HC vs iRBD vs PD groups: 0.672 vs 0.658 vs 0.656) was significantly decreased (P<0.05). The topology was more aggravated in PD group compared with that in iRBD group. Conclusion The graph-based complex brain network analysis can reveal the abnormal topological structure of the brain metabolic network in which iRBD progresses to PD.
