In this manner, a numerical model for the confluent channels was established to study the variation of backwater effects with the parameters in the channel junction. The meeting of flood peaks in the mainstream and tributary can be analyzed with this model.The flood peak meeting is found to be a major factor for the extremely high water level in the mainstream during the 1998 Yangtze River flood. Subsequently the variations of discharge distribution and water level with channel parameters between each branch in this system were studied as well. As a result, flood evolution caused by Jingjiang River shortcut and sediment deposition in the entrance of dividing channels of the Yangtze River may be qualitatively elucidated.It is suggested to be an effective measure for flood mitigation to enhance regulation capability of reservoirs available upstream of the tributaries and harness branch entrance channels.展开更多

Characterized by a sudden eruption of pruritic reticulated, pink-brown papules coalescing into plaques distributed symmetrically over shoulders, neck, chest, and back. Various triggers have been identified, including the ketogenic diet. Clinicopathological presentation looks similar to confluent and reticulated papillomatosis (CARP) which is a rare dermatosis of unknown etiology characterized by hyperkeratotic pigmented papules & peripheral reticulation involving seborrheic areas. Aim: To document a new case presentation of PP caused by a low-carbohydrate restricted diet and discuss the comparison with CARP clinically, pathologically, and treatment modalities. Case report: A 15-year-old childhood male developed PP 3 weeks after self-initiating a low carbohydrate-restricted ketogenic diet for weight management. Clinically and histopathologically the lesion looks similar to CARP, treated successfully with re-introduction of high carbohydrates in his food, a short course of systemic steroids in combination with oral doxycycline capsules for the one-month duration. Conclusion: PP & CARP have been considered a spectrum of one disease, and PP is a pruritic variant from CARP caused by a low carbohydrate-restricted diet.展开更多

Methods：Thirty eligible subjects with chronic pharyngitis were given abdominal acupuncture plus needling Lieque （LU 7） and Zhaohai （KI 6）, two out of the Confluent Points of the Eight Extraordinary Meridian, once a day, 10 sessions as a course, and the therapeutic efficacy was evaluated after a treatment course. Results：After a treatment course, of the 30 subjects, 21 were recovered, 5 showed markedly effective, 2 were improved, and 2 failed,the total effective rate was 93.3%. Conclusion：Abdominal acupuncture plus the Confluent Points of the Eight Extraordinary Meridian is effective in treating chronic pharyngitis, worth promoting in clinic.展开更多
