根据中国和韩国3条树木年轮降水记录,本文分析了过去160a以来东亚夏季风降水的变迁历史。统计分析表明,年际间中国和韩国季风降水不存在线性相关,而在10a尺度上则表现出同步变化的趋势。1860～1890,1910～1925,1940～1960年是3个降水量较多的时段;1890～1910,1925～1940,1960～1998年,则是3个降水量较少的时段。3条降水重建序列均揭示1920年代中期东亚夏季风降水快速由多转少。同时树木年轮季风降水重建序列也被基于中国历史文献记载所划分的旱涝指数和韩国雨量记录所证实。

AIM: To evaluate the therapeutic effects of Gamichunggantang (GCT) on hyperlipidemia through high cholesterol diet model. GCT is an Oriental herbal medication, which has been used for-the treatment of fatty liver, hyperlipidemia or alcoholic liver disease in Daejeon University Oriental Hospital, Korea since 1999. METHODS: Rats were fed with high cholesterol diet for 4 weeks and GCT was administrated for 2 weeks from 2 weeks later in expermental days. The levels of serum total cholesterol, HDL-cholesterol, and triglyceride were analyzed every week. Absolute and relative liver weight to body, and histophathological changes were determined at last day. And, lipid metabolism-related gene expressions (ACAT and DGAT) in liver tissue were analyzed by using RT-PCR. RESULTS:In GCT group, TG levels were reduced at 3 and 4 weeks after GCT administration (39.4%, Pcholesterol levels also were reduced at 3 weeks (20.5%, Pcholesterol levels were increased significantly (Pcholesterol.

Adrenal lymphangioma masquerading as a pancreatic tail cyst

World Journal of Gastroenterology 2014年第36期20卷 13195-13199页

Cystic lymphangiomas of the adrenal gland are rare. A 79-year-old female presented in the emergency room with epigastric discomfort, and an immovable mass was palpated in her abdomen upon physical examination. Imaging studies revealed a large cystic lesion in the pancreatic tail. The radiologic impression ruled out the possibility of a mucinous cystic neoplasm, or a pseudocyst in the pancreas. The operative findings demonstrated that the cystic mass originated in the left adrenal gland. A laparoscopic excision of the cystic mass was performed, and immunohistochemistry confirmed that this mass was a lymphangioma of the adrenal gland. Several prior reports have suggested that lymphangioma can mimic renal or splenic cysts. However, lymphangioma cases mimicking pancreatic cysts are very rare.

Cardiac infiltration of amyloid fibril results in progressive cardiomyopathy with a grave prognosis and results in cardiac diseases such as congestive heart disease, cardiomyopathy, valvular heart disease, and arrhythmias. We present a rare case of cardiac amyloidosis initially misdiagnosed as syndrome X in which recurrent chest pain and progressive heart failure could be managed finally by heart transplantation.

Pancreatic metastasis of leiomyosarcoma in the right thigh:A case report

World Journal of Gastroenterology 2007年第7期13卷 1135-1137页

作者： Yang Seok Koh jung Chul chol Kyoon cho Hyun Jong Kim Division of Hepatobiliary & Pantreatic Surgery Department of Surgery Chonnam National University Medical School Gwangju 501757 Korea

Pancreatic tumors are primary in most of the cases. Pancreatic metastases associated with other primary malignancies, especially pancreatic metastasis of leiomyosarcoma, are uncommon. A 66-year-old woman underwent surgical resection of malignant mesenchymoma （70% osteosarcoma and 30% leiomyosarcoma） in the right thigh. In the postoperative period, a pancreatic mass was identified radiologically by abdominal computed tomography. Pylorus-preserving pancreaticoduodenectomy was performed. The surgical specimen revealed leiomyosarcoma metastasized to the pancreas. A metastatic nodule on the remnant pancreatic tail was discovered 9 mo after the first pancreatic resection, and distal pancreatectomy was performed. Cases of pancreatic metastasis from leiomyosarcoma are extremely rare, especially when the tumor was resectable. We report here a unique case of pancreatic metastasis from a leiomyosarcoma in the dght thigh that had been treated surgically.

Metastatic liver cancer: A rare case

World Journal of Gastroenterology 2005年第27期11卷 4281-4284页

作者： Bong-Wan Kim Hee-jung Wang In-Ho Jeong Sang-Ick Ahn Myoung-wook Kim Department of Surgery

Hemangioperioltoma is a rare tumor especially when it rises in the peritoneal cavity. We present a case of a 60-year-old woman with an isolated recurrent hemangiopericytoma of the liver. The patient presented with a palpable right upper quadrant abdominal mass, which occurred 7 years after undergoing resection of a malignant hemangiopericytoma arising from the greater omentum. She had not followed up 6 mo after surgery. Various imaging studies showed a single large, well-capsulated liver tumor with central necrosis, accompanied by hypervascularity typical of a vascular tumor. Preoperative laboratory HBsAg and anti-HCV workup were both negative. Under the impression of recurrent malignant hemangiopericytoma, right trisegmentectomy was performed to completely resect the tumor. Pathological examination confirmed the diagnosis of recurrent hemangiopericytoma. Even though the incidence of the hemangiopericytoma is relatively low, malignant hemangiopericytoma has a tendency to recur frequently after a long-term disease-free interval. Also, the recurrent hemangiopericytoma is not easily detected early during follow-up until it becomes symptomatic because there are no specific tumor markers, and because of the diversity with regard to site of recurrence. The authors suggest that Positron Emission Tomogram （PET） may be a useful tool for the detection of recurrent hemangioperioltoma. We describe herein some characteristics and behaviors of malignant hemangiopericytoma, particularly after surgical resection.

Comparison of brush and basket cytology in differential diagnosis of bile duct stricture at endoscopic retrograde cholangiopancreatography

引用

Hepatobiliary & Pancreatic Diseases International 2014年第6期13卷 622-627页

作者： Ki Bae Bang Hong Joo Kim jung Ho Park Dong Il Park Yong Kyun cho chong Il Sohn Woo Kyu Jeon Byung Ik Kim Department of Internal Medicine Sungkyunkwan University Kangbuk Samsung Hospital 108 Pyung-Dong Jongro-Ku Seoul 110-746 Korea

BACKGROUND： A previous report has identified a significantly higher sensitivity of cancer detection for dedicated grasping basket than brushing at endoscopic retrograde cholangiopancreato- graphy （ERCP）. This study aimed to compare the diagnostic accuracy of Geenen brush and Dormia basket cytology in the differential diagnosis of bile duct stricture. METHOD： The current study enrolled one hundred and fourteen patients who underwent ERCP with both Geenen brush and Dormia basket cytology for the differential diagnosis of bile duct stricture at our institution between January 2008 and December 2012. RESULTS： We adopted sequential performances of cytologic samplings by using initial Geenen brush and subsequent Dormia basket cytology in 59 patients and initial Dormia basket and subsequent Geenen brush cytology in 55 patients. Presampling balloon dilatations and biliary stentings for the stricture were performed in 17 （14.9%） and 107 patients （93.9%）, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of Geenen brush cytology for the diagnosis of malignant bile duct stricture were 75.0%, 100.0%, 100.0%, 66.7% and 83.3%, respectively, and those of Dormia basket cytology were 64.5%, 100.0%, 100.0%, 58.5% and 76.3%, respectively （P=0.347 and 0.827 for sensitivity and accuracy, respectively）. The good and excellent cellular yields （≥grade 2） were obtained by Geenen brush and Dormia basket cytology in 88 （77.2%） and 79 （69.3%） patients, ***： The sensitivity, specificity and accuracy of biliary sampling with a Dormia basket are comparable to those with conventional Geenen brush cytology in the detection of malignant bile duct stricture.
