The results showed that the dead heart rate（ DHR） ranged from 0. 00% to 38. 55%; new-planting sugarcane of Guiliu 2 and ratoon sugarcane of Liucheng 05-136 suffered the most severe damage in Beihai city,and the DHR were 38. 55% and 37. 66%,respectively. The incidence rate of smut disease ranged from 0. 00% to 24. 89%. Ratoon sugarcane was more susceptible to smut than new-planting sugarcane among all investigated varieties. Variety ROC22 was most susceptible to smut,and performed moderate susceptibility. Guiliu 2 was the second susceptible and performed resistance,with the incidence rate of 7. 45%. The rest nine varieties had high resistance. Sugarcane mosaic disease occurred mildly in Guangxi,and the incidence rate ranged from 0. 39% to 7. 73%. ROC22,Guitang 42 and Guiliu 2 expressed moderate resistance and the rests exhibited resistance. Sugarcane in Nanning and Beihai suffered more severe damage than those in other producing areas. The field evaluation system of sugarcane resistance to borers was expected to be constructed. ROC22 was most susceptible to smut,compared with other main varieties. Mosaic diseases occurred lightly in Guangxi. Multi-location and multi-year observation are necessary for accurate evaluation of sugarcane resistance to smut and mosaic diseases.展开更多
目的:建立列线图预测模型于术前预测甲状腺乳头状癌(papillary carcinoma of the thyroid,PTC)患者出现颈部中央区淋巴结转移(central lymph node metastasis,CLNM)的风险,减少术后并发症的发生概率,达到精准治疗的目的。方法:选择364例...目的:建立列线图预测模型于术前预测甲状腺乳头状癌(papillary carcinoma of the thyroid,PTC)患者出现颈部中央区淋巴结转移(central lymph node metastasis,CLNM)的风险,减少术后并发症的发生概率,达到精准治疗的目的。方法:选择364例PTC患者为研究对象,根据术后中央淋巴结病理学检查结果进行分组。收集患者的一般临床资料及超声资料,利用最小绝对收缩与选择算子(least absolute shrinkage and selection operator,LASSO)回归进行因素选择,多因素logistic回归筛选CLNM的独立影响因素,建立列线图模型以预测CLNM的风险,并通过内部验证评价列线图的应用价值。结果:多因素logistic回归分析示年龄<45岁、结节前后径超过1 cm、结节形态不规则、病灶多发、超声发现可疑淋巴结是PTC患者出现CLNM的独立影响因素(P<0.05)。根据多因素回归结果构建列线图预测模型,其在内部验证中表现出良好的区分度及校准度。列线图模型准确度(0.730,95%CI 0.681~0.775)较单一颈部淋巴结超声(0.638,95%CI 0.586~0.688)显著提高(P<0.001)。结论:基于临床及超声特征建立的列线图能实现PTC患者CLNM的术前预测,有望为临床制订治疗方案提供指导意见。展开更多
