An investigation of Kaschin-Beck disease in Shaanxi Province in 2018 / 中华地方病学杂志

Objective To master the basic conditions of Kaschin-Beck disease areas and patients in Shaanxi Province,and provide a theoretical basis for prevention and control of Kaschin-Beck disease.Methods In 2018,the basic situation of the villages in Kaschin-Beck disease areas of Shaanxi Province and the implementation of prevention and control measures were investigated.The data of general population information,condition and treatment were collected from all the disease affected villages.Results The Kaschin-Beck disease areas of Shaanxi Province involves 4 194 disease affected villages in 62 counties.Among them,3 886 villages had completed the whole village water reform,215 villages changed some of the water,and 93 villages had not changed water;there were 3 835 disease affected villages met the hygienic standard of drinking water,accounting for 91.44％.A total of 60 157 patients with Kaschin-Beck disease were diagnosed.The male-female ratio was 1.0:0.9 (31 531:28 626).The age of the patients was mainly between 40 and 65 years old.There were no new cases of children.Among them,38 448 were degree Ⅰ patients,18 589 were degree Ⅱ patients and 3 120 were degree Ⅲ patients.The occupational distribution of patients was mainly peasant,with 59 703 cases,accounting for 99.25％.The distribution of education was mainly primary school,with 31 108 cases,accounting for 51.71％.There were 876 patients who had completed surgery and 23 284 patients who had been treated with long-term medication.Conclusions In recent years,there is no new case of Kaschin-Beck disease in children in Shaanxi Province.However,the condition of Kaschin-Beck disease in adults is serious,and great efforts should be made in rescue.

Study on Law of Heat Transfer in Zusanli During the Process of Moxibustion at Different Acupoints / 世界科学技术-中医药现代化

Objectvie: To observe the law of heat transfer in Zusanli during the process of moxibustion. Methods: Thetemperature change of Zusanli was detected by self-made high-precision temperature sensor while moxibustion on lowerextremities acupoints on six meridians of foot in healthy volunteers for fifteen minutes, the temperature change curve andtemperature change rate curve were drawn with Origin software. Results: Temperature change curve of Zusanli was thebiggest when moxibustion on acupoints in stomach meridian of foot yangming, especially for Shangjuxu acupoint.Whenthe acupoints near the level of Zusanli are moxibusted, the temperature change curve of Zusanli changes obviously.Temperature change rate curves of Zusanli were basically in coincidence when moxibustion on lower extremities acupoints on six meridians of foot, and it had a downward trend. Conclusion: Heat transfer between meridians andacupoints have propagated sensation along channel, regional characteristics, consistency of transmission rate, in theprosess of moxibustion.
