Objective:To investigate the effects of miRNA-628-3p (miR-628-3p) on the proliferation, apoptosis and invasion of non-small cell lung cancer H1299 cells and its targeting relationship with insulin-like growth factor 1 receptor (IGF-1R).Methods:The blank control group (untreated H1299 cells), miR-NC group (H1299 cells transfected with empty plasmid), miR-628-3p-M group (H1299 cells transfected with miR-628-3p mimic sequence plasmid) and miR-628-3p-I group (H1299 cells transfected with miR-628-3p inhibitory sequence plasmid) were established. The cells in each group were cultured for 72 h, and the cell proliferation ability was detected by methyl thiazol tetrazolium (MTT) method, the number of cell monoclonal formation was determined by crystal violet staining, the level of cell apoptosis was determined by flow cytometry, and the cell invasion ability was determined by Transwell method. The mRNA levels of miR-628-3p and IGF-1R in cells were determined by real-time fluorescence quantitative reverse transcription polymerase chain reaction (qRT-PCR), and the protein level of IGF-1R in cells was determined by Western blotting.Results:Compared with the blank control group and miR-NC group, the cell survival rate [(42±7)% vs. (78±6)%, (76±7)%], the number of monoclonal formation [235±35 vs. 614±89, 618±75], the number of invasive cells [(265±85) cells vs. (693±185) cells, (703±119) cells], relative expression of IGF-1R mRNA (2.17±0.14 vs. 3.38±0.15, 3.37±0.13) and relative expression of IGF-1R protein (0.34±0.13 vs. 0.89±0.19, 0.88±0.18) in the miR-628-3p-M group were lower (all P < 0.05), but the apoptosis rate [(9.30±3.51)% vs. (3.30±1.54)%, (3.10±1.94)%] and relative expression of miR-628-3p (6.93±0.17 vs. 3.29±0.15, 3.30±0.16) were higher (all P < 0.05); the cell survival rate [(90±6)%], the number of monoclonal formation (1 063±102), the number of invasive cells [(1 985±426) cells], relative expression of IGF-1R mRNA (4.30±0.18) and relative expression of IGF-1R protein (1.47±0.17) in the miR-628-3p-I group were higher (all P < 0.05), but the apoptosis rate [(0.90±0.20)%] and the relative expression of miR-628-3p (1.93±0.18) were lower (both P < 0.05). Compared with the miR-628-3p-M group, the miR-628-3p-I group had higher cell survival rate, the number of monoclonal formation, the number of invasive cells, and the relative expressions of IGF-1R mRNA and protein (all P < 0.05), but the apoptosis rate and relative expression of miR-628-3p were lower (both P < 0.05). Conclusions:After regulation of miR-628-3p level, the proliferation, migration and invasion of H1299 cells are affected. miR-628-3p may have a targeting relationship with IGF-1R.

Objective:To investigate the prevalence of uremic pruritus and related factors in patients undergoing hemodialysis.Methods:A total of 212 patients with uremia who undergo hemodialysis in the First Affiliated Hospital of Xiamen University in March 2021 were included in this cross-sectional study. Data including gender, age and blood biochemical indicators were collected. The 5D itch scale was used to evaluate skin itch in patients. The included patients were divided into pruritus and no pruritus groups according to evaluation results. Related indicators were compared between the two groups. Binary logistic regression analysis of skin itch related factors was performed.Results:According to 5D itch scale evaluation results, 129 patients (60.85%) of the 212 patients had no skin pruritus, and 83 patients (39.15%) had skin pruritus. In the pruritus group, age, hypersensitive C-reactive protein, alkaline phosphatase, brain natriuretic peptide, ferritin were 63.0 (51.0, 72.0) years, 1.66 (0.30, 7.85) mg/L, 93.0 (70.0, 118.0) U/L, 192.0 (84.9, 446.4) ng/L and 421.0 (291.6, 577.6) μg/L, respectively, which were significantly higher than 53.0 (42.0, 63.0) years, 0.40 (0.30, 1.88) mg/L, 79.0 (62.0, 99.0) U/L, 143.3 (65.8, 256.5) ng/L, 356.8 (203.3, 528.4) μg/L in the pruritus group ( Z = -3.14, -3.96, -3.05, -2.88, -2.11, all P < 0.05). Increased hypersensitive C-reactive protein, brain natriuretic peptide, ferritin levels ( Wald = 14.58, 4.17, 4.23, all P < 0.05) were independent risk factors for uremic pruritus. Conclusion:Uremic pruritus remains a serious problem in patients undergoing hemodialysis. Increased hypersensitive C-reactive protein, ferritin, brain natriuretic peptide levels are independent risk factors for uremic pruritus. In clinical work, physicians should focus on strengthening the early identification of patients, optimizing treatment measures, and improving the quality of life of patients.

Background: and Purpose The rate of donepezil discontinuation and the underlying reasons for discontinuation in Asian patients with Alzheimer’s disease (AD) are currently unknown. We aimed to determine the treatment discontinuation rates in AD patients who had newly been prescribed donepezil in routine clinical practice in Asia. Methods: This 1-year observational study involved 38 institutions in seven Asian countries, and it evaluated 398 participants aged 50–90 years with a diagnosis of probable AD and on newly prescribed donepezil monotherapy. The primary endpoint was the rate of donepezil discontinuation over 1 year. Secondary endpoints included the reason for discontinuation,treatment duration, changes in cognitive function over the 1-year study period, and compliance as assessed using a clinician rating scale (CRS) and visual analog scale (VAS). Results: Donepezil was discontinued in 83 (20.9%) patients, most commonly due to an adverse event (43.4%). The mean treatment duration was 103.67 days in patients who discontinued. Among patients whose cognitive function was assessed at baseline and 1 year, there were no significant changes in scores on the Mini-Mental State Examination, Montreal Cognitive Assessment, and Trail-Making Test–Black and White scores, whereas the Clinical Dementia Rating score increased significantly (p<0.001). Treatment compliance at 1 year was 96.8% (306/316) on the CRS and 92.6±14.1% (mean±standard deviation) on the VAS. Conclusions In patients on newly prescribed donepezil, the primary reason for discontinuation was an adverse event. Cognitive assessments revealed no significant worsening at 1 year, indicating that continuous donepezil treatment contributes to the maintenance of cognitive function.
