The assistant therapeutic effect of Sanjin tablets used for chronic prostatitis

国际泌尿系统杂志 (2010)

Zhong Tu Hao Liu Tiejun Pan

Objectives To study the assistant therapeutic effect of Sanjin tablets for the patients with chronic prostatitis. Methods To divide 120 chronic prostatitis patients into four groups: Sanjin tablets group(30 cases) treated with Sanjin tablets, Cernilton group(30 cases) treated with Cemilton, combination therapy group(30 cases) treated with Sanjin tablets and Cernilton, control group(30 cases) treated with Qianliekang and norfloxacin,and to analyze the therapeutic effect among four groups. Results The total effective rate in Sanjin tablets group was 70.00%, and those of combination therapy group and control group were 86.67% and 40.00%. Compared with control group and Cemilton group, the total effective rates of Sanjin tablets group or combination therapy group were increased, the differences were statistically significant (x2 = 4.27, p ＜ 0.05 ;x2 = 6.53, p ＜ 0. 01). Conclusions Sanjin tablets may be helpful in the relief of symptom of the patient with chronic prostatitis. Key words: Prostatitis; Chronic Disease

Comparison of Standing Balance Parameters Between Rolling Walker Users and Potential Rolling Walker Users: A Pilot Study

Physical & Occupational Therapy In Geriatrics (2009)

Hao Liu Margaret McGee Victor Prati K. Garrison Qiuyu Fu

To identify differences in balance parameters between older actual rolling walker (RW) users and potential RW users, 26 mentally intact older individuals (13 RW users and 13 potential RW users) participated in this study. All potential users had received recommendations to obtain a RW in the preceding three months because of a history of falls or hospitalization during that time. The test was conducted with each subject performing a static stance without assistance on a force platform with eyes open. The results showed that the ellipse area, path length, and the range and velocity of body sway were significantly larger among the actual users than among the potential users (p <. 05). These suggest that the actual RW users had poorer postural control than the potential users under circumstance without a RW support.

Towards Sustainable Safe Driving: A Multimodal Fusion Method for Risk Level Recognition in Distracted Driving Status

Sustainability (2023)

Huiqin Chen Hao Liu Hailong Chen Jing Huang

Precise driving status recognition is a prerequisite for human–vehicle collaborative driving systems towards sustainable road safety. In this study, a simulated driving platform was built to capture multimodal information simultaneously, including vision-modal data representing driver behaviour and sensor-modal data representing vehicle motion. Multisource data are used to quantify the risk of distracted driving status from four levels, safe driving, slight risk, moderate risk, and severe risk, rather than detecting action categories. A multimodal fusion method called vision-sensor fusion transformer (V-SFT) was proposed to incorporate the vision-modal of driver behaviour and sensor-modal data of vehicle motion. Feature concatenation was employed to aggregate representations of different modalities. Then, successive internal interactions were performed to consider the spatiotemporal dependency. Finally, the representations were clipped and mapped into four risk level label spaces. The proposed approach was evaluated under different modality inputs on the collected datasets and compared with some baseline methods. The results showed that V-SFT achieved the best performance with an recognition accuracy of 92.0%. It also indicates that fusing multimodal information effectively improves driving status understanding, and V-SFT extensibility is conducive to integrating more modal data.

Application of ambulatory orthosis in the rehabilitation of spinal cord injury

Hao Liu

Objective:To study the effect of gait orthosis combined with synthetic rehabilitation therapy on patients with complete spinal cord injury(SCI).Method:A total of 13 cases(10 male and 3 female) with complete SCI were reviewed.Segment injury was one C7,one T4,one T6,ten T10 to L1.Their average age was 33.2 years(21-41 years old).They all accepted the intensified rehabilitation therapy,including the training of muscle power,heart and pulmonary function,ambulation,activities of daily life(ADL),bladder function et al before assembling the gait orthosis.The timed walking function assessment(6min walking test and timed for 10m′s walking),gait analysis,modified Barthel index(MBI) would be performed as indexes to study the effect before assembling the orthosis and after discharged from institution.Result:After assembling and training,their times for 10m walking was 55.2 seconds,6min walking test was 74.9m,step length was 37.9m on average.12 cases accepting the reciprocating gait orthosis(RGO) could finish functional ambulation.One quadraplegia patient could complete therapeutic ambulation by using the advanced reciprocating gait orthosis(ARGO).Their MBI scores improved 31.5 on average after training.Conclusion:Gait orthosis combined with comprehensive rehabilitation therapy has an obvious effect on improving the walking and ADL capacity in patients with complete SCI.

Automatic Recognition and Classification System of Thyroid Nodules in CT Images Based on CNN

Computational Intelligence and Neuroscience (2021)

Wenjun Li Siyi Cheng Qian Kai Keqiang Yue Hao Liu

Thyroid nodule lesions are one of the most common lesions of the thyroid; the incidence rate has been the highest in the past thirty years. X-ray computed tomography (CT) plays an increasingly important role in the diagnosis of thyroid diseases. Nonetheless, as a result of the artifact and high complexity of thyroid CT image, the traditional machine learning method cannot be applied to CT image processing. In this paper, an end-to-end thyroid nodule automatic recognition and classification system is designed based on CNN. An improved Eff-Unet segmentation network is used to segment thyroid nodules as ROI. The image processing algorithm optimizes the ROI region and divides the nodules. A low-level and high-level feature fusion classification network CNN-F is proposed to classify the benign and malignant nodules. After each module is connected in series with the algorithm, the automatic classification of each nodule can be realized. Experimental results demonstrate that the proposed end-to-end thyroid nodule automatic recognition and classification system has excellent performance in diagnosing thyroid diseases. In the test set, the segmentation IOU reaches 0.855, and the classification output accuracy reaches 85.92%.
