The "WuQinXi" exercise, one of the medical Qi-gongs, is an exercise maximizing human's self healing power and has been confirmed to be effective significantly at several modern researches. There are many exercise therapies in western medcine, such as Willams's flexion exercise, Mckenzie's extension exercise, vertebral stabilization exercise and so on. However, there isn't a special exercise therapy which can be applied for medical practice in oriental medicine. So we selected 24 motions which are related with lumbar movements from 3 type "WuQinXi" exercises ; 20 mode, 30 mode, and 40 mode. And then, we classified them according to lumbar movements as flexion, extention, lateral bending and rotation, and also functions as stabilization and rubbing. Next, with these classifications, we assorted them by kinds of lumbar spinal disease as HIVD(herniation of intervertebral disc), spinal stenosis, spondylolysis and spondylolisthesis, facet joint syndrome, compression fracture and spondylosis. We expect that "WuQinXi" exercise be a exercise therapy for lumbar spinal disease at an oriental medical clinic in this way. Oriental medical doctors will be able to teach easily patients "WuQinXi" exercise's motions at clinic, depending on kinds of lumbar spinal disease each patient suffers from. We plan to study the effect of "WuQinXi" exercise by comparing patients who do the "WuQinXi" exercise with the patients who do the western medical exercise therapy.

Background Intima-to-intima microanastomotic vascular remodeling was explored, utilizing a polylactide-caprolactone absorbable vein coupler model (PAVCM), which was designed to simulate a non-absorbable counterpart system with the sole exception of being absorbable. Methods Six New Zealand white rabbits were used. After transection of the jugular vein, 2 PAVCMs were placed, 1 at each transected end. The stumps were slipped through the PAVCMs, and the venous wall was everted $90^{\circ}$ to achieve intima-to-intima contact. Reanastomosis of the transected jugular vein was performed bilaterally in 3 rabbits. In the other 3 rabbits, the jugular vein (20 mm) harvested from one side was interpositionally grafted to the jugular vein on the opposite side to ease the anastomotic tension. Patency testing, ultrasonography, and histologic assessments were conducted postoperatively at weeks 2, 4, 12, 16, 22, and 26. Results All anastomotic sites were patent, without stenosis, occlusion, or dilatation. In the histologic sections, immature endothelial regeneration was observed at week 2, which was completed by week 4. Regeneration of the tunica media was noted at week 12. Between week 22 and week 26, the tunica media fully regenerated and the coupler dissipated entirely. Conclusions Despite the absence of a coupler to act as an anastomotic buttress, the structure and function of all the vessels appeared normal, even histologically. These outcomes are true milestones in the development of an absorbable vein coupler.

Microvascular anastomosis with suture technique is a basic skill but there are several problems such as stenosis, thrombosis and long operating time. Recently plastic surgeons have developed non-suturing mechanical coupling devices for microvascular anastomosis. The authors applied non-penetrating vascular clips (VCS clips) in the field of free flap surgery of head and neck area. Between August of 2004 and January of 2005, we performed 9 free flaps (16 vessels) using small-sized VCS clips. Four stay sutures were applied first and then VCS clips were placed between sutures about 1 mm apart. Vascular pedicle of free flap included the descending branch of lateral circumflex femoral vessel, thoracodorsal vessel, deep inferior epigastric vessel and cephalic vein. The recipient vessels were the superior thyroid artery, superficial temporal artery, internal jugular vein, external jugular vein, and superficial temporal vein. We performed 13 end-to-end (4 arteries and 9 veins) and 3 venous end-to-side anastomoses. No flap related complication occurred but we applied additional clips or sutures in two cases due to blood leakage after completion of anastomosis. Primary patency rates seemed to be good and more rapid anastomosis could be done than conventional suture technique. Advantages of VCS technique are high patency rate, low thrombogenecity and rapidity. Although the high cost of VCS instrument may be a problem, this clip could be applied safely in microvascular free tissue transfer.

Purpose: This study was aimed to develop a new vaginal applicator(Shin's Applicator) for 2-channel high-dose rate vaginal brachytherapy to evaluate uniformity of surface dose, and to present 3-dimensional dose distribution of the applicator. Methods: Shin's Applicator was inexpensively constructed using human soft tissue equivalent acrylic bar. We evaluated dose uniformity along the applicator surface using film densitometer and performed vaginal intracavitary brachytherapy after insertion of the applicator using HDR brachytherapy planning software and brachytherapy unit(Ralstron-20B). Results: Shin's Applicator allows improved dose distribution than the existing 1-channel cylinder and achieves diminished urinary bladder and rectal dose by 20%. Conclusions: From the above results, it can be concluded that Shin's Applicator may be an improved form of a vaginal applicator. Furthermore, it can be suggested that this applicator has an advantage, for it prevents vaginal stenosis after radiation therapy and can be used as a disposable vaginal dilator. Further follow up examination with radiological study may be helpful to evaluate the therapeutic efficacy of this applicator.

Endoscopic submucosal dissection (ESD) was originally developed for en bloc resection of large, flat gastrointestinal lesions. Compared with endoscopic mucosal resection (EMR), ESD is considered to be more time consuming and have more complications for treatment of early esophageal carcinoma, such as bleeding, stenosis and perforation. The objective of this study was to compare the efficacy and safety of ESD and EMR for such lesions. We searched databases, such as PubMed, EMBASE, Cochrane Library and Science Citation Index updated to 2013 for related trials. In the meta-analysis, the main outcome measurements were the en bloc resection rate, the histologically resection rate and the local recurrence rate. We also compared the operation time and the incidences of procedure-related complications. Five trials were identified, and a total of 710 patients and 795 lesions were included. The en bloc and histologically complete resection rates were higher in the ESD group compared with the EMR group (odds ratio (OR) 27.3; 95% CI, 11.5-64.8; OR 18.4; 95% CI, 8.82-38.59). The local recurrence rate was lower in the ESD group (OR 0.13, 95 % CI 0.04-0.43). The meta-analysis also showed ESD was more time consuming, but did not increase the complication rate (P=0.76). The results implied that compared with EMR, ESD showed better en bloc and histologically resection rates, and lower local recurrence, without increasing the incidence of procedure-related complications in the treatment of early esophageal carcinoma.

We have recently experienced a case of decannulation difficulty resulted from head and thoracic injury. The patient was 21-year-old male who undergone craniectomy and tracheotomy at other hospital about 7 months ago prior to admission On admission, there was swelling in glottic and subglottic region in indirect laryngoscopy and bronchoscopy with fixation of vocal cords in paramedian position. We tried to reestablish an adequate air way with bougination using Jackson esophageal bougie but there was no effect with it. So we performed vertical incision through cricoid cartilage and tracheal rings and insertion of Teflon tube in stenotic lesion for 9 months and removed it. At present time, the patient has been satisfactory corking training course.

Arteriosclerosis is a disease in which blood circulation is impaired due to loss of elasticity as blood vessels become narrower, and is a potential cause of recently increasing cardiovascular and cerebrovascular diseases. Carotid ultrasound is used as a predictor of cardiovascular and cerebrovascular diseases by evaluating the degree of atherosclerosis. Therefore, this paper attempted to investigate the correlation between the increase in the thickness of the inner media and various clinical variables in carotid ultrasound. Patients with carotid ultrasound findings were classified into three stages: mild intima thickening, sclerosis, and significant stenosis. CAVI (Carotid Ankle Vascular Index: vascular age) data measured in the degree and physical characteristics of the carotid artery(gender, age, body mass index, blood pressure), blood test(total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, creatine phosphokinase, fasting blood sugar), and arteriosclerosis test were collected. It was confirmed that the carotid intima thickness was correlated with variables such as hypertension, hyperlipidemia, and BMI, and also correlated with the risk factors of cardiovascular disease as CAVI increased.

Background: It is very difficult to choose the ideal valved conduit used in right ventricle outflow reconstruction in child. We can use the cryopreserved homograft but there is a limit of application because of its difficulties in the size matching and supply capacity. The $Shelhigh^{(R)}$porcine-valved conduit is commercially available and used as an alternative choice in these days. We report two cases of early Shelhigh conduit failure in right ventricular outflow tract after Ross operation in congenital aortic stenosis.

The effects of deep hypothermia and circulatory arrest during aortic arch reconstruction are associated with potential neurologic and myocardial injury. We describe a surgical technique that two patients underwent a modified Norwood procedure without circulatory arrest and myocardial ischemia. One was 13-day-old female patient, weighing 3.1kg, having a variant of hypoplastic left heart syndrome and another was 38-day-old male patient, weighing 3.4 kg, diagnosed Taussig-Bing anomaly with severe aortic arch hypoplasia, coarctation of the aorta, and subaortic stenosis. The arterial cannula was inserted in innominate artery directly. During Norwood reconstruction, regional high-flow perfusion into the inominate artery and coronary perfusion were maintained and there were no neurologic, cardiac, and renal complications in two patients. This technique may help protect the brain and myocardium from ischemic injury in patients with hypoplastic left heart syndrome or other arch anomalies including coarctation or interruption.

배경: 대동맥판막협착증 환자는 판막질환으로 인한 만성적인 후부하의 증가에 대한 보상성 좌심실 심근비후가 일어나게 된다. 대동맥 판막 치환 후 좌심실 심근 비후의 감소가 이루어지는 것으로 알려져 있으나 21mm이하의 작은 인공판막으로 치환시 좌심실 심근 변화에 대해 논란이 있다. 대상 및 방법: 1994년 9월부터 1998년 7월까지 한림대학교 강동성심병원 흉부외과에서 대동맥판막협착증으로 진단받고 판막치환술을 시행한 20명을 대상으로 하였다. 환자는 남녀 각각 13명, 7명이며 평균나이 61$\pm$13.8세 체표면적은 평균 1.57$\pm$0.14m$m^2$이었다. 환자의 추적관찰은 수술 전, 수술 후 초기(평균 10.4일) 및 수술 후 만기(평균 29.9개월)에 심초음파로 시행하였다. 환자들은 사용된 판막에 따라 2개의 군(1군;21mm 이하, 2군;23mm이상)으로 나누었다. 결과: 모든 군에서 NYHA Functional class의 유의한 감소가 있었다. 좌심실 구추률은 수술 전후 1군은 유의한 차이가 없었으나 2군에서는 유의한 차이가 있었다. 그러나 수술 전 좌심실 구출률이 2군에서 1군에 비해 유의하게 감소되어 있었다(p=0.044). 좌심실근량지수는 1군은 수술후 초기에 유의한 감소가 없었으나 수술후 만기에는 유의한 감소를 보여주었다. 그러나 2군은 수술후 초기와 만기에 모두 유의한 감소를 보여주었다. 결론: 21 mm이하 군과 23 mm이상 군 모두 임상적 호전이 있었다. 그러나 19 mm판막군이 2례로 적어 19 mm 판막의 사용시 환자의 나이와 체표면적, 운동량을 고려하여 신중한 판막선택이 고려된다.
