Firstly, the water-quality characteristics of intestinal lavage wastewater and enzymolysis wastewater from the typical heparin sodium pro- ductive process were analyzed, and then the segregation treatment was applied in the treatment of enteric coating and heparin sodium manufacturing wastewater. Finally, the treatment of the two kinds of wastewater by different methods were discussed. The results showed that, COD of enzymolysis wastewater treated by centrifugation-coagulation-Fenton reagent oxidation-adsorption process was lower than 100 mg/L, while intestinal lavage wastewater treated by coagulation-ASBR-SBR process could meet the first standard of Comprehensive Discharge Standard of Sewage （GB8978-1996） after one month of continuous operation.

Purpose: To explore the fever-related risk factors of inpatients in Rehabilitation Department, and to provide reference for patients with high risk of fever to take corresponding nursing measures. Methods: The study was conducted on the Rehabilitation Department of The First Affiliated Hospital of Jinan University from July 2019 to December 2019. The fever group included 51 patients and the non-fever group included 49 patients without fever. The two groups of clinical data, comorbidities, related laboratory values, possible risk factors of fever were analyzed by case regression analysis, and the relevant risk factors were screened out by LASSO (least absolute shrinkage and selection operator) regression analysis. Results: According to the results of Lasso regression analysis, pressure sore or skin infection, history of hypertension, current history of respiratory tract infection, feeding patterns were the higher risk factors of fever in inpatients in Rehabilitation Department, while the first course of disease, main diagnosis, history of respiratory tract infection within half a year, kidney damage and hospitalization days were lower risk factors. Conclusion: This study is helpful to early identify the fever risk of inpatients in Rehabilitation Department, and provide reference basis for high-risk fever patients to take positive and effective nursing measures.

This paper discusses the developement and investigation of a silica microbubble resonator(MBR) that is optimized to cancel mode dispersion with material dispersion, at a wavelength of approximately 1550 nm and maintain a quality factor of an optical mode as large as 5.4 × 10~7. Benefitting from the near-zero dispersion and high quality factor, a primary optical comb is generated in the MBR using cascaded four-wave mixing processes, which span over 300 nm with several tens of teeth. Furthermore, the frequency comb could be gradually tuned by mechanically stretching the MBR. This tunable Kerr comb has multiple potential applications in precision measurements and sensing applications, such as molecular spectroscopy and ranging.

Objective: This paper aims to explore clinical status and related influence factors of pressure injury (PI) in the elderly inpatients with kidney disease, so as to provide reference for the prevention and treatment of PI in the elderly inpatients with kidney disease. Methods: Retrospective collection method is adopted to collect 158 clinical cases of the elderly inpatients with kidney disease aged ≥ 60 in the Nephrology Department, the First Affiliated Hospital of Jinan University from January 2017 to December 2019, and then least absolute shrinkage and selection Operator (LASSO) regression analysis is used to analyze 17 possible influence factors;finally Logistic regression model is established to analyze and screen influence factors of risk. Results: 1) Among 158 elderly inpatients with medium and high risk of PI, the incidence of PI is 20.25%;the most common stage of injury is stage I (42.5%);sacrococcygeal (60%) is the high-risk site of pressure injury. 2) LASSO regression analysis shows that history of present respiratory infection/respiratory failure (β = 1.2714. P β = 0.4177. P Conclusion: The elderly patients with kidney disease and PI risk are the high incidence population of hospital acquired PI;for the elderly inpatients with kidney disease and having respiratory infection history or respiratory failure, prolonged hospitalization will significantly increase the risk of PI. Therefore, targeted preventive and control measures should be taken to reduce the incidence of PI.

提出一种基于支持向量机的自适应图像空域水印嵌入算法.由于支持向量机与人眼视觉系统在自学习、泛化和非线性逼近等方面具有极大的相似性,算法利用支持向量机模拟人眼视觉特征,结合图像的局部相关特性,自适应地确定图像的最佳嵌入位置和嵌入强度.首先,利用无导师的模糊聚类分析方法对图像各像素进行初步的聚类,为有导师的支持向量机找到分类规则;然后,从各类别中选出隶属度超过一定阈值的像素作为支持向量机分类的训练样本集,建立支持向量机的分类模型,根据此模型对图像各像素再次分类,从而确定水印的最佳嵌入位置;最后结合图像自身的局部相关性,自适应地调整水印嵌入位置的像素值.该算法在提取水印时不需要原始载体图像.实验结果表明,此算法对多种图像处理均具有很好的稳健性和图像感知质量,其性能优于相关文献上的相近方法.
