In order to realize an individualized and specialized rehabilitation assessment of remoteness and intelligence, we set up a remote intelligent assessment system of upper limb movement function of post-stroke patients during rehabilitation. By using the remote rehabilitation training sensors and client data sampling software, we collected and uploaded the gesture data from a patient's forearm and upper arm during rehabilitation training to database of the server. Then a remote intelligent assessment system, which had been developed based on the extreme learning machine (ELM) algorithm and Brunnstrom stage assessment standard, was used to evaluate the gesture data. To evaluate the reliability of the proposed method, a group of 23 stroke patients, whose upper limb movement functions were in different recovery stages, and 4 healthy people, whose upper limb movement functions were normal, were recruited to finish the same training task. The results showed that, compared to that of the experienced rehabilitation expert who used the Brunnstrom stage standard table, the accuracy of the proposed remote Brunnstrom intelligent assessment system can reach a higher level, as 92.1%. The practical effects of surgery have proved that the proposed system could realize the intelligent assessment of upper limb movement function of post-stroke patients remotely, and it could also make the rehabilitation of the post-stroke patients at home or in a community care center possible.

Objective To assess the usefulness of combined dual-energy CT pulmonary angiography (DE-CTPA) and indirect CT venography (CTV) in the diagnosis of venous thromboembolism (VTE).Methods Forty-nine patients with leg swelling suspected of pulmonary embolism (PE) underwent both DE-CTPA combined with CTV and lower extremity venous ultrasound (US) in 1-2 days prior to CT.Image quality of CTPA and dual energy lung perfusion image (DEPI) was rated using a 5-point scale and the coherence between CTPA and DEPI was analyzed by Kappa statistics.The ability of CTV and US in the diagnosis of deep venous thrombosis (DVT) was compared by Chi-square test.Results Twenty-nine of 49 patients were identified with PE by DE-CTPA,including 28 patients identified by CTPA and one more by DEPI,and 21 patients were found to have both PE and DVT.Both DE-CTPA and DEPI had positive findings for pulmonary embolism in 19 patients and both had negative findings in 18 patients.There was a moderate agreement between DEPI and DE-CTPA in the assessment of PE (Kappa value =0.7534).Thirty-eight patients with DVT were identified by US,while 35 patients were identified by CTV.Among the 35 patients with DVT identified by CTV,pelvic veins were involved in 25 patients,while the inferior vena cava was involved in 3 patients.There was no significant difference between CTV and US in the diagnosis of DVT(P =0.625).The detection rate of VTE with DE-CTPA combining CTV was 30.6% higher than that with CTPA alone.Conclusions The combined DE-CTPA and CTV achievesone-stop examination.It not only provides evaluation of PE and DVT and increases detection of VTE,but also depicts perfusion defect of pulmonary parenchyma that corresponds to PE.

Objective To prospectively study the main risk factors of variceal bleeding in cirrhotic patients. Methods Fifty-seven patients with liver cirrhosis and esophageal varices who had never experienced variceal bleeding were followed up for 12 months. The patients underwent measurements of esophageal variceal pressure by non-invasive endoscopic balloon technique. The endpoint of the study was the presence of a variceal hemorrhage. The relationship between variceal hemorrhage and endoscopic findings including varices, variceal pressure, Child-Pugh status, ascites, and etiology of cirrhosis was studied. Results Thirty-four patients (59.6% ) developed a variceal hemorrhage. In univariate analysis, the level of variceal pressure (P= 0. 001), the size of varices (P=0. 006), and the endoscopic red color sign on the variceal wall (P=0. 012) predicted higher risks of variceal hemorrhage. The multiple logistic regression revealed that variceal pressure was a major predictor of the risk for a first variceal bleeding (OR=2. 817, P=0. 003). The area under the receiver operating characteristic (ROC) of variceal pressure for predicting variceal bleeding was 0. 98, and the variceal pressure cutoff value was 25.3 mm Hg (1 mm Hg=0. 133 kPa) with both specificity and sensitivity of 91 %. Conclusion The level of variceal pressure is a major predictor for variceal bleeding in cirrhotic patients.

Objective To investigate inhibitory effects of Oridonin on the proliferation of cultured rabbit conjunctival fibroblast (RCF). Design Experimental study. Participants Cultured RCF obtained from filtering area after trabeculectomy. Methods Trabeculectomy was performed in rabbits. On day 7 after surgery, subconjunctival tissue from filtering area was obtained for culturing RCF in vitro. Cultured RCFs were exposed to different concentration Oridonin (5, 10, 20, 30, 40, and 50 ?mol?L-1) for 48h, respectively. The proliferation of RCF was investigated by MTT assay at different time points. Main Outcome Measures Optical density (OD) value of RCF and inhibitory rate of cell growth. Results OD values of each concentration Oridonin group (5, 10, 20, 30, 40, and 50 ?mol?L-1) were (0.402?0.013), (0.347?0.011), (0.293?0.015), (0.236?0.022), (0.184?0.023), and (0.125?0.014), respectively. These data showed a significant difference compared with the OD value (0.453?0.015) of control group without Oridonin (P=0.021-0.000). The inhibitory effects showed a significant difference in a dose-dependent manner (F=5.48, P=0.003). Oridonin (5, 10, 20, 30, 40 and 50 ?mol?L-1) sup-pressed the proliferation of RCF in vitro at rates of 11.26%, 23.40%, 35.32%, 47.90%, 59.38% and 72.41%, respectively. Conclusion Oridonin can inhibit the proliferation of cultured RCF obtained from filtering area. The effect is in a dose-dependent manner. This indicates that Oridonin is most likely to be a novel agent to prevent excessive scarring following glaucoma surgery.
