Objective To explore the diagnosis and trealanent of closed tracheal,bronchial injury.Methods The clinical features,early diagnosis and treatment about 7 cases of closed treacheal,bronchial injury wrerarolyzed.Results 3 cases of tracheal injury in neck were cured after urgent repairment:1 case of membranous tracheal chest injury was cured after drainage about mediastinal;the 3 cases of tracheobronchial injury were cured by sutured,patched and formed.Conclusion The key measure of increase the cure rate,reduce complications and reduce morality is early diagnosis and timely-reasonable treatment.

Enterprise resource planning is systematic management thought and means established on the basis of information technology,which provides management platform for the decision-makers and staffs to make the decisions.By using IT technology,ERP closely integrates material flow,information flow,capital flow,management flow,and knowledge flow of a enterprise,which facilitates resource optimization and sharing.ERP can be introduced into the hospital drug management.Using advanced information and logistics technology,hospital drug mannagement can be strengthened on such aspects as drug purchase,drug storehouse management,dispensing management in pharmacy,capital settlement and rational use of drug,and so on.Therefore,the hospital drug management can be improved by achieving planning in advance,real-time tracing back,effective control and rational use.

Objective To investigate the early endotracheal intubation line to attract the effect of meconium aspiration. Methods April 2005 to April 2007 the relevant cases (A group) and April 2007 to April 2009 the related cases ( B group) were compared. Results B group and A group efficacy was superior (P < 0.05). Conclusion Early tracheal intubation attract ideal effect of meconium aspiration, it is worth promoting.

Life system and medicine are both complex systems. Recently, traditional biologists have acquired tremendous data from high-speed development of all kinds of species group. However, how to use these data to interpret the mechanisms of diseases and health has become the research target of current investigators. The booms of system biology provide new thought and research methods to tackle this problem. This paper emphasizes the relationship between system biology and traditional Chinese constitutional medicine.

Objective To establish a method for the determination of hymecromone content and dissolution in Compound Dantong Capsules by HPLC.Methods The content and dissolution of hymecromone was determined by HPLC.The chromatographic conditions were: CAPCELL PAK C18 Column(5 ? m,4.6 mm? 150 mm),methanol-0.01 mol/L phosphate buffer solution(465 ∶ 535) as mobile phase,detection wavelength at 365 nm and the injected volume being 10? L.Dissolution test was performed with 150 mL of water as dissolving medium and with a rotation speed of 100 r? min-1.Results A good linearity of hymecromone was in the range of 0.25 ? g/mL～ 1.75 ? g/mL(r=0.9989),and the average recovery was 99.4 %,RSD=1.60 %(n=5).The dissolutions of 3 batches of samples in 45 minutes were higher than 70 % of the labeled amount,which accorded with the standard.Conclusion This method was simple and accurate,has no interference of other components,and can be used for the quality control and evaluation of Compound Dantong Capsules.

Bibliographic database of TCM periodicals was used as data source and hand-foot-mouth disease was used as subject for searching. Based on periodicals resource of hand-foot-mouth disease in this database, we analyzed the current situation of preventing and treating hand-foot-mouth disease by bibliometrics method, providing references for scientific studies.

Objective To evaluate the clinical efficacy of absolute ethanol combined with histoacryl sclerotherapy in treating high-reflux venous malformation in children.Methods The clinical data of a total of 339 sick children with venous malformation,who were admitted to authors' hospital during the period from April 2009 to April 2014 to receive interventional sclerotherapy under general anesthesia,were retrospectively analyzed.Sclerotherapy with absolute ethanol combined with N-butyl cyanoacrylate (NBCA) was carried out in 137 sick children with high-reflux type venous malformation.The patients were followed up for 6-24 months (mean of 15 months).Results Successful sclerotherapy with absolute ethanol combined with NBCA was achieved in all 137 sick children with high-reflux type venous malformation.Complete cure was obtained in 23 sick children,basic cure in 31 sick children,and effective response (improvement) in 42 sick children;the total effective rate was 70％ (96/137).Ectopic embolization due to reflux of NBCA occurred in one sick child,skin ulceration was seen in 8 sick children and intraoperative transient pulmonary hypertension was observed in 3 sick children.The adverse reaction rate was 8％(12/137).Conclusion For the treatment of high reflux venous malformation in children,sclerotherapy with absolute ethanol plus NBCA is safe and effective,this technique carries low incidence of adverse reactions.(J Intervent Radiol,2017,26:217-220)

Objective To study the value of multi-slice spiral CT (MSCT)urography in diagnosis of urinary obstructive disease.Methods 48 cases with urinary system obstructive disease confirmed by operotion underwent MSCT scan,including plain and multi-phase contrast-enhanced scans.The images of CTA and CT urography were obtanined by the different three dimensional reconstruction.Results Of 48 cases,there were renal and uretal congenital malformation in 15 cases,uretal negative stone in 4,urinary inflammation in 5 ,renal,uretal and bladder tuberculosis in 6,hydronephrosis and hydroureterosis caused by exterior compression in 8 and neoplasm of urinary system in 10.Conclusion Multi-slice spiral CT urography is of significant applied value in diagnosis of urinary obstructive diseases.
