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.

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.

Objective To evaluate the applied value of multislice spiral CT multiplanar reconstruction in diagnosing the trauma oforbit. Methods 40 patients with trauma of orbit underwent multislice spiral CT scan, the thickness of slices was 2 mm and collimator was 0.75 mm. Multiplanar reconstruction (MPR) and free angle parallel ranges reconstruction (PRR) were performed. CT findings of orbital trauma were analysed. The result passes through the surgery and the clinical confirmation.Results 14 cases with radiopaque foreign in orbit comfirmed by operation were accurately localized by MPR and PRR, but 6 cases were misdiagnosed by conventional CT. There were 21 cases with fracture of orbital wall, of them, 9 cases were not detected or partially misdiagnosed by plain CT. The damage of eye musculus rectus was in 16 cases, 6 cases were diagnosed by MPR+PRR. There were 16 cases with eyeball damage, of them , 4 cases detected by conventional CT difficultly, but they identified by MPR and PRR. The damage of optic nerve was in 5 cases, 4 cases were not discovered by conventional CT. Conclusion MPR and PRR are of important value in evaluating the orbital trauma.

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.

Objective To investigate the therapeutic effect of acupuncture combined with Vitalstim electric stimulation therapy for treatment of patients with dysphagia after ischemic stroke.Methods Ninety-two patients with dysphagia after ischemic stroke in accord with the criteria of enrollment in this study were admitted to the Department of Acupuncture of the First Affiliated Hospital of Tianjin Traditional Chinese Medicine University from May 2014 to November 2016, and they were divided into a control group and an observation group by random number table, 46 cases in each group. Both groups were treated with stroke conventional drug therapy and feeding swallowing rehabilitation training, in addition, Vitalstim swallowing therapeutic electrical stimulation therapy was used in the control group, and acupuncture combined with Vitalstim stimulation were applied in observation group. The changes of swallowing ability score, video fluoroscopic swallowing study (VFSS) score and adverse reactions were observed before and after treatment in the two groups, and the curative effect of combined method was evaluated.Results Compared with those before treatment, the swallowing ability and VFSS score of two groups after treatment were obviously higher, and the degrees of changesin observation group were more significant than those in control group (swallowing score: 8.12±1.13 vs. 7.45±1.04, VFSS score: 7.97±1.05 vs. 5.67±0.88, allP < 0.05); the total efficiency in the observation group was markedly higher than that in the control group [95.7% (44/46) vs. 78.3%(36/46)], the adverse reactions (wrong aspiration, pulmonary infection) in the observation group were significantly lower than those in the control group [10.9% (5/46) vs. 28.3% (13/46)], and there were statistically significant differences between the two groups (bothP < 0.05).Conclusions Acupuncture combined with Vitalstim electric stimulation therapy can improve the swallowing ability in patients with dysphagia after ischemic stroke, and the therapy has less adverse reactions; compared with the simple Vitalstim electric stimulation therapy, in the aspect of improving swallowing ability, the therapeutic effect of combined therapy is more significant.

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 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)

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.
