Objective To investigate the value of Color Doppler ultrasound in hemodynamic changes of non-alcoholic fatty liver disease.Methods 120 cases with non -alcoholic fatty liver disease were selected and divided into the mild group,moderate group and severe group.According to the degree of fatty infiltration of the liver taxono-my,40 cases in each group,hemodynamic changes of each group were detected in Color Doppler ultrasound equip-ment.Results Hepatic venous pulse waveform analysis and comparison constituted of the three groups and control group,the difference was statistically significant (χ2 =25.343,P <0.05).PPVV,MPVV,HARI of the three groups and control group were compared,the difference was statistically significant(F =34.67,51.03,31.06,all P <0.05).Conclusion Color Doppler ultrasound which is used to detect hemodynamic changes in non -alcoholic fatty liver disease had good clinical value,can assess disease progression in patients,can provide the basis for clinical treat-ment.

Total 1350 subjects were selected by cluster random sampling from Chongwen District and Shijingshan District in Beijing with a populations of 100 000.Chongwen District represented a typical urban district and Shijingshan represtnted a newly extended urban district.Qualified investigators conducted face-to-face survey using the uniform questionnaire and measurement, dealing with the knowledge, attitude and behavior for risk factors of stroke in two districts.The results showed:in Chongwen District, the awareness rates of "the diagnostic criteria of hypertension", "antihypertensive drugs can lower the risk of cardiocerebral vascular disease", and "criteria for obesity" were 71.3%, 87.3% and 22.9% respectively,which were significantly higher than those in Shijingshan District.The awareness rate of "bad temper may increase the risk of cardiocerebral vascular disease" was lower in the Chongwen District.There were no significant differences in attitude between two districts.In Chongwen District the level of three risk factors (smoking and obesity) was significantly lower than Shijingshan, but action of self-examination was also significantly lower.Generally, there was higher level in health knowledge and lower level of risk factors in Chongwen District.The hypertension-related knowledge and behavior was not entirely consistent.It is necessary to transform knowledge into behavioral changes or intervention of risk factors in population with high awareness like Chongwen District.

Objective To analyze the influencing factors of hematoma complicated from ultrasound-guided minimally invasive surgery for benign breast masses.Methods Retrospective analysis was performed in 412 patients with a total of 516 masses underwent the ultrasound-guided minimally invasive surgery for benign breast masses from January 2011 to December 2015 in Xiaoshan Hospital. Theχ2 test was used to univariately analyze risk factors of hematoma formation after ultrasound-guided minimally invasive surgery for benign breast masses. Logistic regression analysis was used to multivariately analyze risk factors of hematoma formation.Results All masses were resected completely, however, hematomas with long diameter≥1.0 cm were formed in 43 masses one week after surgery, and all hematomas were completely absorbed after six months. There were significant differences in the incidence of hematoma between the groups of different needle sizes, numbers of needle cutting, masses sizes, blood flow grades, depth, resection numbers and effective compression time of postoperative bandages (χ2=16.917, 14.548, 39.971, 23.333, 29.137, 36.819 and 39.864, respectively, allP<0.001). The needle sizes, the numbers of needle cutting, the masses sizes, blood flow grades, depth, resection numbers and the effective compression time constituted the risk factors of hematoma formation after the minimally invasive surgery.Conclusions The risk factors of the hematoma formation after ultrasound-guided minimally invasive surgery for benign breast masses included the different size of the needle, the number of different cutting needles, different size of the masses, the grade of blood flow, the number of resection and the different effective compression time of postoperative bandages. We could prevent the occurrence of hematoma in advance by screening patients and take corresponding measures.

Bacterial β-glucuronidases (BGUSs) are an important type of hydrolase produced by gut microbiota and play an important role in tumor development and chemotherapy by deconjugating a large number of endogenous and exogenous glucuronides. In recent years, BGUSs inhibition has emerged as a promising approach to reduce cancer risk and alleviate gastrointestinal toxicity of chemotherapy drugs. However, a growing body of evidence underlines great genetic and structural diversity, functional promiscuity, and varied inhibition propensity of BGUSs, which have posed enormous challenges to identifying BGUSs involved in a specific pathophysiological or pharmacological process and developing effective inhibitors. In this review, we summarize the latest advances in structure and function of BGUSs and review the findings of BGUSs-mediated carcinogen reactivation and deconjugation of chemotherapy drugs in recent years, as well as the discovery of BGUSs inhibitors and preclinical investigation of their applications in cancer prevention and drug therapy. Finally, we discuss the prospects of BGUSs inhibition as a new strategy for tumor prevention and drug therapy.

Severe and critically ill patients with coronavirus disease 2019 (COVID-19) were usually with underlying diseases, which led to the problems of complicated drug use, potential drug-drug interactions and medication errors in special patients. Based on ( 6), and -19: , we summarized the experience in the use of antiviral drugs, corticosteroids, vascular active drugs, antibacterial, probiotics, nutrition support schemes in severe and critically ill COVID-19 patients. It is also suggested to focus on medication management for evaluation of drug efficacy and duration of treatment, prevention and treatment of adverse drug reactions, identification of potential drug-drug interactions, individualized medication monitoring based on biosafety protection, and medication administration for special patients.
