Qingyang progress in Kashin-Beck disease prevention and control research

. 0 of about 56.0% of fourth year. Results are basically unchanged for four years. These results show that the change of water on Kashin-Beck Disease in a certain role, for which more than 450 million state investment,[link widoczny dla zalogowanych], the establishment of a variety of disease prevention and water improvement projects in various 1100, the ward more than 98,500 on the clean drinking water . Second, the selenium and the relationship between Kashin-Beck disease epidemiology survey showed that: Kashin-Beck disease in China are mainly distributed in low selenium areas, ward water and soil selenium content in grain than non-endemic area, ward and more people with low selenium content in bulk in 20g/kS, more than a typical ward lOg / kg, was lower in children with endemic selenium as the center of metabolic disorders, additional selenium ward population can effectively control the disease, Kashin-Beck disease is proposed for this occurrence and Selenium lack. . 1974, provincial, prefectural, and county formed a research collaboration with Kashin-Beck disease control group, the trial in the County too Chang selenite, vitamin E treatment of Kashin-Beck disease trial, after observation, that appointment of the two drugs on children are satisfied with Kashin-Beck disease effect. Treatment after 3 to 6 months, x-ray examination of bone metaphyseal lesion repair rate above 80, more than all the drugs used in the past. May 1977 to May 1983, research group in collaboration Hsinchuang County administrative villages with Kashin-Beck disease were seriously ill simple application of sodium selenite in prevention of Kashin-Beck disease test. 3 to 13 years for children age 6 years was observed, x ray normal children (normal children with X ray detection rate targets) before the detection rate of 57.45% from the drug rose to 95.91 in 1983,[link widoczny dla zalogowanych], pilot areas to control the disease, so that collaborative group of comrades obtained intake of Kashin-Beck disease and selenium deficiency-related conclusions. To explore this argument provides a new clue to the cause, the state and provincial awards. In order to change the way medicine ', Qingyang learn from overseas experience, in 1984, starting 1 / 60000 in the County are selenium salt pilot, after trial, affirmed the success of salt, selenium, and in 1986 to promote the implementation in the region changed the ward and children's medication in patients with difficult conditions. Third, food poisoning, said fungi in China in the mid sixty attention and to study the epidemiology and food can be seen the same ward water from different sources, the incidence was significantly different. Ward change in the dry paddy field, change the staple food after rice, corn Kashin-Beck Disease Control that the ward is a pathogenic factor of food into the body of the carrier. Ward out of the grain harvest, drying process was fungal contamination, when the toxin production in the humid Kashin-Beck Disease is the main way. Kashin-Beck patients in the district, ward wide, ward and at the plateau and gully banks, food is quite difficult to change fields, real difficult to carry out research into this area, this without doing the experiment. Kashin-Beck disease monitoring to closely monitor disease Kashin-Beck disease in dynamics, in order to facilitate the smooth progress of prevention and control work, to continue to master the control effect of selenium, 1986 to 1988, I conducted the early clinical Kashin-Beck disease to watch. Select the town from 1987 to 1989 on the original Shaw, County osmanthus garden field, Qingyang Xian tower for the condition monitoring points. In 1990, developed a new large, severe disease in prison Island Festival program,[link widoczny dla zalogowanych], the time required under the program, method, object, index content, select the Qingyang the Green Fields, the original of the town of Shaw, co-Forest as a condition of water due to gate monitoring points, has been observed 7 years, the results for: 1990 x 7 ~ l2-year-old children in the town line was originally positive rate of 26.39, Qingyang 36. il, combined water as 38.64, the detection rates were 25.0,33.33,30.68 metaphysis. 1996 x ray positive detection rate was 9.43%, 7.84,6. 59; metaphyseal detection rates were 7.55,7.84,4.40. The work of the three monitoring points is still continuing. Throughout the seven years of monitoring results; 7 ~ l2-year-old x ray is extremely positive detection rate has dropped significantly, this change must have clear important factor in its change as a prerequisite. Etiology is not fully clear in the case, the district used to change water,[link widoczny dla zalogowanych], selenium, changing living conditions,[link widoczny dla zalogowanych], hygiene, groceries and other integrated control measures, especially after the Third Plenary Session, changes in economic conditions in rural areas, people's living standards increased significantly decreased both the disease played a certain role, and this is the general consensus prevention researchers to continue to continue to use the integrated control measures necessary. Cause of Kashin-Beck disease is currently not yet clear, it was reported that the disease is also very heavy in some areas, under certain conditions, Kashin-Beck disease is still the possibility of recovery, so the changes can not relax condition monitoring, research seeking the cause will be a long-term work, the implementation of control measures must be carried out conscientiously adhere to.
