ObjectiveTo explore the antioxidant and anti-human cervical cancer HeLa cell effect and mechanisms of Andrographis paniculata polysaccharide (APP). MethodCell function assays were conducted to assess the effects of APP (400, 450, 500 mg·L-1) on the proliferation, migration, and invasion of HeLa cells using the cell counting kit-8 (CCK-8) assay, scratch assay, and Transwell assay. Molecular mechanism experiments were conducted to detect the effects of APP on HeLa cell apoptosis and cell cycle-related mRNA and protein expression using flow cytometry, real-time fluorescence-based quantitative polymerase chain reaction (Real-time PCR), and Western blot analysis. The antioxidant activity of APP was tested using DPPH+, OH-, and reducing power assays. ResultCompared with the blank group, APP (400, 450, 500 mg·L-1) significantly inhibited the migration, proliferation, and invasion abilities of HeLa cells in a time- and dose-dependent manner (P<0.05, P<0.01). Flow cytometry with propidium iodide (PI) single staining was used to detect cell cycle. The results showed that compared with the blank group, the proportion of HeLa cells in the G2/M phase increased after 48 hours of treatment with APP (400, 450, 500 mg·L-1), indicating that APP can arrest HeLa cells in the G2/M phase. Flow cytometry with fluorescein isothiocyanate (Annexin V-FITC)/PI apoptosis kit was used to detect cell apoptosis. Compared with the blank group, the proportion of early and late apoptotic HeLa cells increased in a dose-dependent manner after 48 hours of APP (400, 450, 500 mg·L-1) treatment (P<0.05, P<0.01), indicating that APP promotes HeLa cell apoptosis. The results of Real-time PCR and Western blot assay showed that compared with the blank group, after 48 hours of APP (400, 450, 500 mg·L-1) treatment resulted in decreased mRNA and protein expression of cell cycle-dependent kinase-1 (CDK-1), Cyclin B1, and B-cell lymphoma-2 (Bcl-2), and increased mRNA and protein expression of cysteine aspartate protease (Caspase)-3, Caspase-8, Caspase-9, and Bcl-2-associated X protein (Bax) (P<0.05, P<0.01). These findings were consistent with the flow cytometry results and showed a dose-dependent effect. In vitro antioxidant tests demonstrated that different concentrations of APP (50-1 000 mg·L-1) were able to scavenge DPPH+ and OH- radicals, indicating certain antioxidant activity. ConclusionAPP possesses antioxidant activity and can inhibit the viability of HeLa cells while promoting their apoptosis.

Background::Understanding willingness to undergo pulmonary function tests (PFTs) and the factors associated with poor uptake of PFTs is crucial for improving early detection and treatment of chronic obstructive pulmonary disease (COPD). This study aimed to understand willingness to undergo PFTs among high-risk populations and identify any barriers that may contribute to low uptake of PFTs.Methods::We collected data from participants in the "Happy Breathing Program" in China. Participants who did not follow physicians’ recommendations to undergo PFTs were invited to complete a survey regarding their willingness to undergo PFTs and their reasons for not undergoing PFTs. We estimated the proportion of participants who were willing to undergo PFTs and examined the various reasons for participants to not undergo PFTs. We conducted univariable and multivariable logistic regressions to analyze the impact of individual-level factors on willingness to undergo PFTs.Results::A total of 8475 participants who had completed the survey on willingness to undergo PFTs were included in this study. Out of these participants, 7660 (90.4%) were willing to undergo PFTs. Among those who were willing to undergo PFTs but actually did not, the main reasons for not doing so were geographical inaccessibility ( n = 3304, 43.1%) and a lack of trust in primary healthcare institutions ( n = 2809, 36.7%). Among the 815 participants who were unwilling to undergo PFTs, over half ( n = 447, 54.8%) believed that they did not have health problems and would only consider PFTs when they felt unwell. In the multivariable regression, individuals who were ≤54 years old, residing in rural townships, with a secondary educational level, with medical reimbursement, still working, with occupational exposure to dust, and aware of the abbreviation "COPD" were more willing to undergo PFTs. Conclusions::Willingness to undergo PFTs was high among high-risk populations. Policymakers may consider implementing strategies such as providing financial incentives, promoting education, and establishing community-based programs to enhance the utilization of PFTs.

Acute kidney injury (AKI) is an important factor for the occurrence and development of CKD. The protective effect of dihydroartemisinin on AKI and and reported mechanism have not been reported. In this study, we used two animal models including ischemia-reperfusion and UUO, as well as a high-glucose-stimulated HK-2 cell model, to evaluate the protective effect of dihydroartemisinin on premature senescence of renal tubular epithelial cells in vitro and in vivo. We demonstrated that dihydroartemisinin improved renal aging and renal injury by activating autophagy. In addition, we found that co-treatment with chloroquine, an autophagy inhibitor, abolished the anti-renal aging effect of dihydroartemisinin in vitro. These findings suggested that activation of autophagy/elimination of senescent cell might be a useful strategy to prevent AKI/UUO induced renal tubular senescence and fibrosis.

Objective:To explore the change in cerebral blood flow when healthy subjects swallow hot and ice water, and to verify the sensitivity of functional near-infrared spectroscopy (fNIRS) in identifying liquid temperatures while swallowing as a basis for applying it in diagnosis and intervention.Methods:Sixteen healthy subjects swallowed hot and ice water in randomized order while the process was recorded using fNIRS. The activation at rest and when swallowing hot and ice water was compared pairwise.Results:Compared with the resting state, 19 channels were activated during the swallowing of the hot and ice water. The common activated areas were S1, M1, PMC, SMA, Wernicke′s area, the somatosensory association cortex, the visual association cortex and the frontal eye field. However, the dorsal lateral prefrontal cortex was activated only when swallowing hot water, and the subcentral area was activated only when swallowing ice water. The SMA and PMC were significantly more activated when swallowing hot water than ice water.Conclusions:Multiple brain regions are activated and participate in regulating swallowing. The PMC and SMA areas can distinguish hot water from ice water swallowing.
9.Two year follow up of myopia cohort in central Jiangsu Province
Chinese Journal of School Health 2022;43(9):1298-1300
Objective:
Based on observational, longitudinal and intervention study of common diseases among students in Jiangsu Province, this paper presents the current progress of two year follow up of myopia cohort regarding the association between growth parameters with progression of myopia among children and adolescents in areas with rapid economic growth.
Methods:
This survey adopted the stratified cluster sampling method for school selection. The full automatic computer optometry (TOPCON RM800) was used to track myopia related parameters for all participants from 2019 to 2020 under the condition of mydriasis (compound topicamide eye drops). Relationship between growth parameters of children and adolescents and the incidence and progression of myopia was analyzed by using Cox regression multiple statistical model.
Results:
The myopia rates of students from grade 1 to grade 3 in 2019 were 5.4%, 21.5% and 37.3% respectively. After one year, the myopia rates of all school stages increased to 25.3%, 43.3% and 58.1% respectively( χ 2=53.59, 49.63, 32.52, P <0.01). The mean diopter of right eye and left eye after mydriasis were ( 0.30± 1.24/0.39±1.26)D in 2019 and (-0.33±1.54/-0.19±1.55)D in 2020, respectively based on Cox multiple regression results, age ( HR =1.21, 95% CI =1.09-1.34), naked eye vision ( HR =0.08, 95% CI =0.07-0.11), height ( HR =0.98, 95% CI =0.97-0.99) showed a strong correlation with the incidence and progression of myopia( P <0.05).
Conclusion
Myopia is growing rapidly in the central region of Jiangsu Province. It is suggested that diopter, axial length, naked eye vision, age, height and other indicators should be included in the refractive archives of children and adolescents in the region.
