Paclitaxel is one of the commonly used drugs in postoperative chemotherapy for ovarian cancer patients. However, affected by drug dosage and individual differences in the course of medication, patients will have different degrees of adverse reactions, which will cause damage to the patient’s body once they occur. This paper retrospectively analyzed the clinical data of patients with severe allergic reactions such as fecal incontinence and numbness of hands and feet caused by the use of paclitaxel liposome during postoperative chemotherapy in a case of ovarian cancer admitted to our hospital. The causes and corresponding treatment measures were analyzed, in order to provide the reference for medical staff to take effective countermeasures in advance in the future.

Fuzzy c-means （FCM） algorithm is one of the most popular methods for image segmentation. However, the standard FCM algorithm is sensitive to noise because of not taking into account the spatial information in the image. An improved FCM algorithm is proposed to improve the antinoise performance of FCM algorithm. The new algorithm is formulated by incorporating the spatial neighborhood information into the membership function for clustering. The distribution statistics of the neighborhood pixels and the prior probability are used to form a new membership func- tion. It is not only effective to remove the noise spots but also can reduce the misclassified pixels. Experimental results indicate that the proposed algorithm is more accurate and robust to noise than the standard FCM algorithm.

目的:分析1990~2021年全球及中国归因于烟草(吸烟和二手烟)的心血管疾病负担及其变化趋势。方法:基于2021年全球疾病负担(GBD)研究数据库,分析1990~2021年全球及中国归因于烟草的心血管疾病(包括缺血性心脏病、脑卒中、心房颤动/心房扑动、主动脉瘤和外周动脉疾病)的年龄标化死亡率及伤残调整寿命年(DALY)率及其年估计变化百分比(EAPC),并评估人类发展指数(HDI)、社会人口学指数(SDI)与年龄标化死亡率的相关性。结果:较1990年,2021年全球归因于吸烟的心血管疾病负担下降,年龄标化死亡率从57.2/10万降至26.3/10万(EAPC=-1.81%,95%CI:-2.00%~-1.63%);全球归因于二手烟的心血管疾病负担下降,年龄标化死亡率从11.4/10万降至8.3/10万(EAPC=-1.72%,95%CI:-1.91%~-1.53%)。中国归因于吸烟的心血管疾病负担下降,年龄标化死亡率从52.2/10万降至39.6/10万(EAPC=-1.23%,95%CI:-1.44%~-1.02%);中国归因于二手烟的心血管疾病负担下降,年龄标化死亡率从15.3/10万降至14.7/10万(EAPC=-1.26%,95%CI:-1.63%~-0.90%)。值得注意的是,中国女性归因于二手烟的心血管疾病负担下降超过全球水平,中国女性年龄标化死亡率由17.9/10万降至14.5/10万(EAPC=-2.24%,95%CI=-2.78%~-1.86%)。全球及中国可归因于烟草的5类心血管疾病中,主动脉瘤、缺血性心脏病、外周动脉疾病的年龄标化死亡率、年龄标化DALY率均较高。Pearson相关性分析显示,年龄标化死亡率越高的国家,未来的疾病负担将呈上升趋势。此外,HDI及SDI是影响疾病负担的两个主要因素,在SDI>7.2的国家/地区,年龄标化死亡率低于预测水平。在预测后期,中国的年龄标化死亡率出现下降趋势。结论:1990~2021年,全球及中国归因于烟草的心血管疾病负担均有所下降,特别是女性的疾病负担下降最显著。在SDI<7.2的国家/地区,疾病负担仍然显著。因此,需要针对重点地区(中国、东亚、中欧、中亚及东南亚地区)采取控烟措施,积极降低吸烟率和公共场所二手烟暴露,从而减轻人群心血管疾病负担。

Reconstruction of trace metal pollution histories and sources may help us to regulate current pollutant discharge. This is especially important for the highland lakes in southwestern China, which are facing trace metals pollution. We present sedimentary records of 11 metals accumulated in Yangzong Lake since the 1870＇s, a highland lake in southwestern China. Pollution of lead and zinc （Pb and Zn） was differentiated based on principal component analysis, geochemical normalization, and lead isotope ratios. Nearly all the metals as well as grain size composition show generally constant values before the mid-1980＇s, denoting stable detrital input in the catchment. Fluctuations in the concentrations of the metals as well as grain size composition since the mid-1980＇s indicate an increase in soil erosion with strengthened human disturbance in the catchment. After geochemical normalization, Pb and Zn showed constant values before 1990 AD and then a gradual increase in parallel with the variations in 2~spb/~~6pb and 2~7pb/2~6pb ratios, indicating that Pb and Zn pollution occurred. Combining the data of 20PPb/206Ppb and 207Pb/206Pb ratios in the sediments of Yangzong Lake, leaded gasoline, Pb-Zn ore and coal, and consumption or production historical trends, we deduced that the enhanced Pb and Zn pollution in Yangzong Lake is caused primarily by ore mining and refining.
