Objective To strengthen physiatrist's knowledge of diagnosis and treatment of venous thromboembolism by analysing 7 venous thromboembolic events in rehabilitation. Methods 7 cases with venous thromboembolism (VTE) in our department were involved in this study. Related data of these patients were collected, investigated and analyzed. Results 6 cases were deep venous thrombosis (DVT), 1 case was pulmonary embolism (PE). The patients with DVT were treated successfully by thrombolytic and/or anticoagulant therapy as well as later rehabilitation treatment, and the patient with PE was cured after intra-arterial mechanical thrombolysis therapy and later anticoagulant therapy. Conclusion Prevention and treatment of VTE is becoming a very important issue in development in our country. Active prevention, early recognition and treatment are very important for the prognosis of patients with VTE.

Objective To establish an appropriate cut-off value of high sensitivity cardiac troponin T (hs-cTnT) and optimal combination measurement in the early diagnosis of acute myocardial infarction (AMI).Methods This research is a prospective study.342 patients admitted to emergency department with chest pain,43 patients with renal failure,40 patients with pneumonia and 18 premature with patent ductus arteriosus were involved from June 2012 to June 2013 in Peking University Third Hospital.The plasma hs-TnT,NT-proBNP,cardiac troponin Ⅰ (cTnI),CK-MB and copeptin were measured.The distribution of hs-cTnT among associated diseases was analyzed,the diagnostic performance of hs-cTnT and the role of combination hs-cTnT with NT-proBNP,CK-MB and copeptin were evaluated by receiver operating characteristic (ROC) curve.The statistical method was used to calculate the Sensitivity,specificity,negative predictive value and positive predictive value of hs-cTnT in the diagnosis of AMI.Results As compared to patients with STEMI(median 0.52 μg/L,range 0.037-7.610 μg/L),hs-cTnT was lower in the patients with Non-STEMI(median 0.127 5 μg/L,range 0.021-4.260 μg/L).However,the levels of hs-TnT in other diseases were also increased increased in varyng degrees (Chi-square =76.432,P ＜ 0.05)The areas under the curve (AUC) for hs-cTnT and cTnI in the diagnosis of AMI were 0.862 (95％ CI:0.729-0.928) and 0.748 (95％ CI0.666-0.818) respectively (Z =2.713,P ＜ 0.05).Taking 0.014μg/L and 0.035 μg/L as cut-off value of hs-TNT,the sensitivities were 100％ vs 95.1％,the specificities were 44.4％ vs 65.7％.The combination of hs-cTnT,NT-proBNP,CK-MB resulted in a increase in AUC (0.915,95％ CI:0.838-0.964) (Z =2.147,P ＜ 0.05) and the combination of hs-cTnT and copeptin resulted in a increase in AUC 0.921 (95％ CI:0.820-0.975) (Z =2.589,P ＜ 0.05).Conclusion With the cut-off value of 0.035 μg/L for diagnosis of AMI was appropriate,and the combination measurement can improve the accuracy of early diagnosis of AMI.

OBJECTIVE To study the bactericidal efficacy of glutaraldehyde,and its stability and change in pH value.METHODS The carrier quantity bactericidal test,field mimic bactericidal test,stability test,pH value detection,periodical biological surveillance and follow-up investigation of hospital infection were used.RESULTS After using of 20 000 mg/L of neutral glutaraldehyde on Candida albicans(ATCC 10231),Pseudomonas aeruginosa(ATCC27853),Escherichia coli(ATCC 25922) and other 3 clinical isolates separately for 3,5,and 10 min,the average killing rate was 97.90%,99.83% and 100.00%;on the field mimic bactericidal test with MRSA contaminated gastroscope,the average killing rate was 87.84%,99.50%,and 100.00%,respectively.The concentration of disinfectant after storaging 14d on 54℃ was decreased,only loss 1.46%,the concentration loss of disinfectant on using endoscope 5,7,and 14d after disinfection was 2.64%,0.69% and 0.94%,respectively.The value of pH was decreased from 7.22 to 6.00,6.50,and 6.20.The qualification rate of 260 various endoscopes after surveillance was 100.00%.Their was one of hospital infection happened among 3 200 patients after endoscopy which were followed up.CONCLUSIONS The results show that,only under the following circumstances,namely the concentration of glutaraldehyde being no less than 20 000mg/L and the action time being no less than 10 min,timely alteration of glutaraldehyde,and regular biological and concentration monitoring could the disinfection of endoscope be qualified so that hospital infection can be prevented,and medical dispute may be put to an end.

Objective To study the chemical constituents of Swertia decora, a traditional herb used to treat hepatitis by the minority.Methods The constituents were separated and purified by column chromatography with silica gel.Their structures were identified on the basis of spectral analysis such as UV, MS, NMR, HMPC, HMQC and by HPLC.Results Three compounds were isolated from the chloroform part and ethyl acetate part of the extracts.Their structures were identified as 1-hydroxy-4, 5, 6, 7-tetra- methoxy -9H-xanthen-9-one (swertiadecoraxanthone-Ⅰ, Ⅰ), 5, 7, 3′, 4′- tetrahydroxyflavone (luteolin, Ⅱ), and 3, 5, 7, 3′, 4′-pentahydroxyflavone (quercetin, Ⅲ), respectively.Conclusion Swertiadecora- xanthone -Ⅰ is a new compound and the other two are found from this plant for the first time.The pentaoxygenated patterns of compound Ⅰ is also found for the first time in the plants of Swertia L.

Objective To analyze the clinical effects of bronchoscope combined with hot and cold ablation in treatment of benign and malignant tumors in primary tracheal and bronchial. Methods From January 2013 to November 2015, 30 cases of pathological types of primary tracheal / bronchial benign and malignant tumors patients include: 8 cases of hamartoma, 1 case of lipoma, 4 cases of granuloma, 1case of clear cell carcinoma, 7 cases of small cell lung cancer, 9 cases of squamous cell carcinoma, were treated by using carbon dioxide cryotherapy combined hot ablation under bronchoscope. Then investigated the outcomes. Results 30 patients, 22 males, 8 females, suffered from 1 month to 2 years, underwent surgery bronchoscope interventional treatment under local anesthesia combined with intravenous anesthesia, are taking joint cold ablation technique. All patients airway is completely opened, the lifting of the airway obstruction. Including 19 cases of disposable surgical removal of the lesion; 8 cases of lesions due to wide distribution, 2 times surgery; three cases three times surgery, no serious complications, follow-up without recurrence, blood gas analysis and dyspnea index were significantly improved. Conclusion Bronchoscope cold joint ablation techniques in the treatment of primary tracheal, bronchial benign and malignant tumors is effective, simple, minimally invasive and safe.

Objective To study the effects of motor imagery therapy combined with electromyographic (EMG) biofeedback on upper limb function in hemiplegic patients.Methods Sixty hemiplegic stroke patients were recruited and divided into a control group (n=20),an electrical stimulation group (n=20) and a combination group (n=20).All groups received basic medication and routine rehabilitation training once daily for 4 weeks.The electrical stimulation group was also treated with EMG biofeedback,and the combination group with motor imagery therapy plus EMG biofeedback.The Fugl-Meyer assessment (FMA),the modified Barthel index (MBI) and EMG parameters were assessed before and after 2 courses of treatment.Results After 8 weeks of treatment all groups had significantly higher FMA scores and MBI scores,and better integrated EMG values,but the effects in the combination group were significantly better than those in the other two groups.Conclusions Motor imagery therapy combined with EMG biofeedback can more effectively promote recovery of upper limb function in hemiplegic stroke patients.

The symbiotic bacterium exists in the intestines of entomopathogenic nematodes and is a potential biological agent.Systematic classification of these bacteria is scarce in China.In this paper,seven strains of symbiotic bacteria from local entomopathogenic nematodes were identified by both observation of mor-phology,physiological,biochemical characteristics and sequence analysis of 16S rDNA fragments.
