Objective To investigate the effect and its mechanism of ziyuglycoside Ⅱ on proliferation, migration, invasion and apoptosis of colon cancer cells HT-29. Methods The effect of ziyuglycoside Ⅱ on cell proliferation of colon cancer cells HT-29 was determined by CCK-8 method; the effect of ziyuglycoside Ⅱ on cell migrative capacity of colon cancer cells HT-29 was determined by scratch assay; the effect of ziyuglycoside Ⅱ on cell invasive capacity of colon cancer cells HT-29 was determined by transwell assay; the effects of ziyuglycoside Ⅱ on cell apoptosis of colon cancer cells HT-29 was determined by flow cytometry; the effects of ziyuglycoside Ⅱ on mRNA and protein expression of protein kinase B (AKT)/phosphatidylinositol-3-kinase (PI3K) signal pathway were determined by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and western-blot, respectively. Results Ziyuglycoside Ⅱ (0, 1, 5, 10, 20, 40, 60 and 80 μmol/mL) inhibited proliferation of colon cancer cells HT-29 in a dose-dependent manner. Ziyuglycoside Ⅱ (5, 10 and 20 μmol/mL) inhibited migration of colon cancer cells HT-29 in a dose-dependent manner. Ziyuglycoside Ⅱ (5, 10 and 20 μmol/mL) inhibited invasion of colon cancer cells HT-29 in a dose-dependent manner. Ziyuglycoside Ⅱ (5, 10 and 20 μmol/mL) promoted apoptosis of colon cancer cells HT-29 in a dose-dependent manner. Ziyuglycoside Ⅱ (5, 10 and 20 μmol/mL) increased mRNA expression of AKT and PI3K, decreased mRNA expression of Caspase-3 and Caspase-9. Ziyuglycoside Ⅱ (5, 10 and 20 μmol/mL) increased protein expression of phosphorylated protein kinase B(p-AKT) and phosphorylphosphatidylinositol-3-kinase (p-PI3K), increased the expression of Cleaved-Caspase-3 and Cleaved-Caspase-9 protein. Conclusion Ziyuglycoside Ⅱ can inhibit proliferation, migration and invasion of colon cancer cells HT-29, and promote the apoptosis of colon cancer cells HT-29. Its mechanism may be related to regulating the signal pathway of AKT/PI3K via promoting phosphorylation of AKT and PI3K protein, activation of Caspase-3 and Caspase-9 protein.

Objective:Inhaler satisfaction is an important factor affecting inhaler adherence and the efficacy of inhalers in chronic airway diseases.Using a scientific and effective method to assess patients'satisfaction with inhalers is of great significance for improving clinical outcomes.The Feeling of Satisfaction with Inhaler-10(FSI-10)is specifically designed to assess patients'inhaler satisfaction in chronic airway diseases,but the application research on this scale is not available in China.This study aims to evaluate the reliability and validity of the Chinese version of FSI-10,describe the current status of inhaler satisfaction and discuss the associated variables in Chinese patients with chronic airway disease. Methods:Based on the English version of FSI-10,items of the Chinese version of FSI-10 were determined after forward-backward translation and cultural adaption.Totally,322 patients with chronic obstructive pulmonary disease(COPD)and asthma were enrolled from the Second Xiangya Hospital of Central South University from June to October 2022.We collected associated clinical variables and inhaler satisfaction using the Chinese version of FSI-10.The content validity of the scale was expressed by content validity index(CVI)and the construct validity was analyzed by exploratory factor analysis(EFA).The reliability of the scale was expressed by Cronbach's α coefficient,the split-half reliability and test-retest reliability.A multivariate logistic regression was conducted to examine variables related to inhaler satisfaction. Results:The reliability and validity analysis showed that the CVI was 0.983.One factor was extracted from the Chinese version of FSI-10 and the cumulative variance contribution rate was 73.114%.The Cronbach's α of the scale was 0.913,the Guttman's half-reliability coefficient was 0.905,and the test-retest reliability was 0.727(P<0.001).In addition,the total score of the scale for patients was 38.92±4.26 points and the proportion of high satisfaction(the score of FSI-10≥40)in patients with COPD was significantly lower than that in asthma patients(71.3%vs 87.9%,P<0.01).Older age(age≥70 years)was a risk factor of lower inhaler satisfaction and asthma diagnosis was a protective factor. Conclusion:The Chinese version of FSI-10 has good reliability and validity in patients with COPD and asthma,which may be further promoted and applied in patients with chronic airway disease in China.Doctors should regularly evaluate the inhaler satisfaction of patients with chronic airway diseases,especially for those elder or with severe symptoms and a long course of illness.

【Objective】 To analyze the basic characteristics of whole blood donors from blood stations before and after the outbreak of COVID-19. 【Methods】 After excluding invalid data, data related to the basic characteristics of whole blood donors collected from 26 blood stations in China during 2018 to 2021 were statistically analyzed, including the trend of total whole blood donors, the number of repeated blood donors, the frequency of blood donation, the average age of donors and the recruitment of first-time blood donors. 【Results】 Affected by the epidemic, 8 out of 14 indicators were with large variations, accounting for 57%. The overall growth rate of total whole blood donors during the epidemic was higher than before the epidemic (P<0.05).The number of repeated blood donors has shown an increased trend, with a higher number during the epidemic than before (P<0.05). The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic, both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors <25 years old and ≥25 years old varied widely and irregularly during the epidemic (both P<0.05). The percentage of first-time blood donors fluctuated irregularly during the epidemic, with overall percentage lower than that before the epidemic(P<0.05). 【Conclusion】 Whole blood donors from 26 blood stations increased after the outbreak of COVID-19, and some indicators in certain areas showed significant fluctuations during the epidemic.

Evaluate the effect of the fresh air purification system on the improvement of indoor PM 2.5 levels in a primary school classroom in Jinan City, Shandong Province. Our purpose is to explore the optimal operating time of the fresh air system and the main factors that affect the fresh air purification system to improve indoor air quality. From December 9, 2019 to December 10, 2019, two classrooms of the same area on the third floor of a primary school building in Jinan City, Shandong Province were selected as monitoring points. During the operation of the fresh air purification system, the PM 2.5 concentration in the classroom is reduced by an average of 48.1%-61.5% compared to the outdoor PM 2.5 concentration. After running for about 2 hours, the indoor PM 2.5 concentration decreased to a relatively stable concentration level. The operating time of the fresh air purification system, student activities between classes, indoor temperature, indoor relative humidity, and outdoor PM 2.5 concentration are important factors that affect the indoor particulate removal rate. In the case of a certain amount of fresh air and indoor area, closing doors and windows and appropriately extending the operation time of the fresh air purification system can improve the air quality in the classroom to a certain extent and protect the health of students.

OBJECTIVES: To investigate the clinical characteristics and risk factors for severe events of coronavirus disease 2019 (COVID-19) in elderly patients. METHODS: Retrospective analysis was performed on the clinical data of all elderly COVID- 19 patients treated in Changsha Public Health Treatment Center from January 17, 2020 to March 15, 2020, which included basic diseases, symptoms, test results, and other clinical characteristics, and prognostic indicators such as severity of illness, length of hospital stay, virus shedding time and mortality rate. The differences in clinical characteristics and prognostic indicators between elderly, middle-aged, and young COVID-19 patients were also analyzed. Logistic regression model was used to conduct univariate and multivariate analysis of risk factors for developing severe events in elderly COVID-19 patients; receiver operating characteristic (ROC) curve analysis was used to evaluate the prediction efficacy. RESULTS: Of the 230 COVID-19 adult patients, 34 were young patients (14.8%), 136 were middle-aged patients (59.1%), and 60 were elderly (26.1%). Among the 60 elderly patients, 23 were male (38.3%) and 37 were female (61.7%), with a medium age of 66 years old. Common symptoms were fever (66.7%), cough (50.0%), and fatigue (41.7%). C reactive protein (CRP) was increased significantly. The proportion of severe cases was 31.7%, and mortality was 1.7%. The median length of hospitalization and median virus shedding time were 18.5 days and 21 days, respectively. Compared with the young and the middle-aged patients, the elderly had a higher proportion of hypertension, diabetes, and cardiovascular diseases, more common shortness of breath, higher proportions of pneumonia and severe cases (all <0.05), and the decreased lymphocyte count and lymphocyte percentage (both <0.05), as well as higher CRP and erythrocyte sedimentation rate (ESR) levels (both <0.05). Compared with non-severe cases, severe elderly patients demonstrated higher CRP and aspartate aminotransferase (AST) levels (all <0.05), the reduced lymphocyte count (<0.05), and the prolonged length of hospitalization and virus shedding duration (both <0.05). Univariate logistic regression analysis indicated that the lymphocytes proportion, CRP and AST levels were significantly correlated with the risk for developing severe events in elderly COVID-19 patients (all <0.05). Multivariate logistic regression found that severe events in elderly patients with COVID-19 were significantly correlated with CRP level (OR=1.041, =0.013). ROC curve analysis revealed that the area under the curve (AUC) for CRP to diagnose severe events in elderly COVID 19 patients was 0.851. CONCLUSIONS The proportion of severe cases in elderly COVID-19 patients is higher than that in young and middle-aged patients. CRP level has a good predictive value for the possibility of severe events in elderly COVID-19 patients.
