金属园环因其经济、简便、长效、副作用较小,故在我国城乡广泛使用;其突出的缺点是脱落率高。我地区农村首次放环第一年净累积脱落率为30%,国内有报道达36.7%。所以对首次放环对象作脱落预测有现实意义。国内学者已提出用计算脱落概率的方法来预测放环对象脱环的机会。我们也认为多次脱环者(占我院门诊放环总数的4.25%)尤其是频脱环者,其个体本身可能存在容易脱环的客观因素,临床上对此
Due to its economy, economy, simplicity, long-term effect and small side effects, the metal garden ring is widely used in urban and rural areas of our country. Its outstanding drawback is its high exfoliation rate. For the first time in rural areas in our region, the net cumulative shedding rate was 30% in the first year and 36.7% in China. Therefore, it is of practical significance to make the shedding forecast for the first putting ring object. Domestic scholars have proposed using the method of calculating the probability of shedding to predict the chances of deprotonation of a target. We also believe that many times those who take off the ring (accounting for 4.25% of the total number of outpatient release ring in our hospital), especially the frequency off the ring, the individual itself may exist an objective factor easy to de-loop, clinically
