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 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.

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 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.
