It shares borders with China on the north and Thailand on the east. Kengtung is a place which forms a significant historical site in the easternmost part of Myanmar. From the geopolitical point of view, the region was located in a most strategic place. Its situation forced to safeguard the region. The town lies on a critical point of Myanmar’s defences. The restriction of exacting money as a yearly tribute did not concern for Kengtung. The tradition of paying homage was appeased to the King. The ruling Sawbwa which achieved the valuable return presents of the Burmese King. Kengtung came in the first class, and was the most important of the Myanmar’s possessions east of the Thanlwin River. Its position may be roughly judged by the tribute paid to the King and the contigent it was bound to supply to the royal army. Therefore, Kengtung was very important for the security of Myanmar’s eastern frontier during the Konbaung period. It was like a small Union within an Empire together with multinational races of Myanmar. A good deed of past events blanket over the town till today.展开更多

On the basis of sorting out landscape city, space structuring of the northern foot of the Qinling Mountains was studied within the theoretical framework of landscape city, it was disclosed that northern foot of the Qinling Mountains was a signifi cant ecological screen for the landscape city spatial pattern of Xi'an, and an important carrier for its "mountain, water and city" cultures. Then, fi ve infl uence factors for the space structuring of the study area were given, and basic contents of the space structuring analyzed from fi ve perspectives of spatial structure, spatial form, ecological environment, integration of regional spaces, historical and cultural context, so as to explore ecological conservation and moderate utilization of the northern foot of the Qinling Mountains from the perspective of space structuring.展开更多

The management of a WOPN depends on its location and on patient's symptoms. Trans-gastric drainage and debridement of WOPN represents an important surgical treatment option for selected patients. The da Vinci surgical System has been developed to allow an easy, minimally invasive and fast surgery, also in challenging abdominal procedures. We present here a case of a WOPN treated with a robotic trans-gastric drainage using the da Vinci Xi. CASE SUMMARY A 63-year-old man with an episode of acute necrotizing pancreatitis was referred to our center. Six wk after the acute episode the patient developed a walled massive fluid collection, with an extensive pancreatic necrosis, causing obstruction of the gastrointestinal tract. The patient underwent a robotic transgastric drainage and debridement of the WOPN performed with the da Vinci Xi platform. Firstly, an anterior ideal gastrotomy was carried out, guided by intraoperative ultrasound (US)-scan using the TilePro? function. Then, through the gastrotomy, the best location for drainage on the posterior gastric wall was again US-guided identified. The anastomosis between the posterior gastric wall and the walled-off necrosis wall was carried out with the new EndoWrist stapler with vascular cartridge. Debridement and washing of the cavity through the anastomosis were performed. Finally, the anterior gastrotomy was closed and the cholecystectomy was performed. The postoperative course was uneventful and a post-operative computed tomography-scan showed the collapse of the fluid collection. CONCLUSION In selected cases of WOPN the da Vinci Surgical System can be safely used as a valid surgical treatment option.展开更多

In front of him, the old dilapidated scenes have all disappeared. The former nine 1.9-meter-wide lanes have become 12 six-meter-wide roads. The former crowded courtyards, 11 stairs down the lanes, have completely changed their outlook. The only things that seem to have not changed are the old Beijing style of blue tiles and gray bricks and the imperial city walls nearby that are the witnesses to all these changes. Grandpa Qin is among the 300 households who have returned after the rebuilding project was completed. Qin’s family lived in the Nanchizi community for five generations. The big展开更多
