Surgical treatment and ESI （epidural steroid injection） are widely used forms of treatment for cervical radiculopathy but they are controversial and burdensome for patients. To relief pain fast without side effects, we devised a new minimally invasive treatment method that widens the facet joints to decompress nerve roots and release the muscle spasm in cervical radiculopathy with acupuncture needles with blunt tip and mini-scalpel, and named it modified acupuncture procedure. MAP （Modified acupuncture procedure） was administered for 37 patients （mean age = 53.1 years, follow-up = 14.2 months） with cervical radiculopathy who did not recover from 4 weeks of nonsurgical treatment. We analyzed clinical outcomes of patients before and after the procedure through VAS （Visual Analogue Scale） and NDI （Neck Disability Index）. On average, patients received 1.4 MAP （modified acupuncture procedures）. The VAS score difference on the day after procedure and at 1 year follow-up was 36.8 ± 26.5 （from 60.1 ± 25.3 at the baseline to 25.3 ± 17.8 at the reading）（P 〈 0.01） and 31.0 ± 30.4 （29.0 ± 21.8 at the reading） respectively. The NDI value dropped by 19.9 ± 18.3 （from 37.2 ± 19.7 at the baseline to 17.2 ± 15.0 at the reading）（P〈 0.01） on 1 year follow up. MAP was found to have clinical efficacy for cervical radiculopathy.

Network-adaptive HD MPEG-2 video streaming with cross-layered channel monitoring in WLAN

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2006年第5期7卷 885-893页

作者： PARK sanghoon yoon Hayoung KIM Jongwon Networked Media Laboratory Department of Information and Communications GwangJu Institute of Science and Technology Gwangju 500-712 Korea

In this paper, we propose a practical design and implementation of network-adaptive high definition (HD) MPEG-2 video streaming combined with cross-layered channel monitoring (CLM) over the IEEE 802.11a wireless local area network (WLAN). For wireless channel monitoring, we adopt a cross-layered approach, where an access point (AP) periodically measures lower layers such as medium access control (MAC) and physical (PHY) transmission information (e.g., MAC layer loss rate) and then sends the monitored information to the streaming server application. The adaptive streaming server with the CLM scheme reacts more quickly and efficiently to the fluctuating wireless channel than the end-to-end application-layer monitoring (E2EM) scheme. The streaming server dynamically performs priority-based frame dropping to adjust the sending rate according to the measured wireless channel condition. For this purpose, the proposed streaming system nicely provides frame-based prioritized packetization by using a real-time stream parsing module. Various evaluation results over an IEEE 802.11a WLAN testbed are provided to verify the intended Quality of Service (QoS) adaptation capability. Experimental results showed that the proposed system can mitigate the quality degradation of video streaming due to the fluctuations of time-varying channel.

Radiotherapy for 65 patients with advanced unresectable hepatocellular carcinoma

引用

World Journal of Gastroenterology 2008年第15期14卷 2394-2400页

作者： Yeon Seok Seo Jin Nam Kim Bora Keum sanghoon Park Yong Dae Kwon Yong Sik Kim yoon Tae Jeen Hoon Jai Chun Chul Yong Kim Chang Duck Kim Ho Sang Ryu Soon Ho Um Department of Internal Medicine Korea University College of Medicine Seoul 136-705 Korea Department of Radiation Oncology Korea University College of Medicine Seoul 136-705 Korea

AIM: To evaluate the efficacy of radiotherapy (RT) in patients with advanced unresectable hepatocellular carcinoma (HCC). METHODS: A total of 65 patients were treated with RT in the Korea University Medical Center. The median age of the patients was 60 years, and 86.2% were men. 18.5% and 81.5% of the patients were diagnosed as TNM stage Ⅲ and Ⅳ-A, respectively. Treatment response was assessed 4 mo after initiation of RT. Tumor regression rate 1 mo after initiation of RT (TRR1m) was also assessed. Duration of survival was calculated from the initiation of RT. RESULTS: The objective treatment response was 56.9%. The 12 mo survival rate was 34.7%. Predictive factors for survival were Child-Pugh grade, α-fetoprotein level and treatment response. An objective response was achieved more frequently in patients with TRR1m ≥ 20% than in those with TRR1m < 20% (P < 0.001). CONCLUSION: RT is effective in treating advanced HCC with a tumor response rate of 56.9%.
