BACKGROUND: Dialysis-related amyloid may occur during long-term dialysis for patients with uraemia, of which the main evocator is β_2-microglobulin (β_22M); therefore, how to eliminate 132M from blood is always the focus of research. OBJECTIVE: To observe ability of removal of β_2-microglobulin (β_2M) from serum using two kinds of polyethersulfone (PES) membrane materials with various degrees of sulfonation.METHODS: These materials were incubated in radio-labeled β_2M (~(125)Ⅰ-β_2M) solution and human serum respectively at appointed time at 37 ℃, and then the amounts of ~(125)Ⅰ-β_2M and serumβ_2M adsorbed by materials were measured by radio immunoassay. RESULTS AND CONCLUSION: In the ~(125)Ⅰ-β_2M system, amounts of ~(125)Ⅰ-β_2M adsorbed by the materials decreased in the following sequence PES with high degree of sulfonation > PES with low degree of sulfonation > PES, whatever the source of PES was. In the serum system, amounts of β_2M adsorbed reached maximums at 30 minutes and the final adsorptions decreased in sequence of PES with high degree of sulfonation > PES with low degree of sulfonaUon > PES. Sulfonated PES removed β_2M more than PES did and the adsorption of β_2M increases with the increase in the degree of sulfonation. Its ability to remove significant amount of β_2M may result in less β_2M available for incorporation into amyloid. The use of sulfonated PES membranes may lessen the likelihood of development of dialysis-related amyloidosis, which remains a major source of morbidity for patients treated with long-term hemodialysis.

Objective:To investigate the mechanism of histone deacetylase (HDAC) inhibitor in down-regulating the expression of HER-2 in breast cancer cells and to provide an innovative therapeutic option to overcome the disadvantages of anti-HER-2 therapy. Meth-ods:HER-2-positive breast cell lines were treated with HDAC inhibitors. The changes in the gene and protein levels of HER-2 were de-tected by qPCR and Western blot. MiRNA microarray was used to identify the HDAC inhibitors, whereas qPCR was used to verify the miRNA expression. Results:In vitro cell experiments confirmed that the HDAC inhibitors TSA and SAHA can down-regulate the expres-sion of HER-2 in breast cancer cell lines. TSA can down-regulate the expression of HER-2 gene in BT474 and decrease the concentra-tions of 100 nmol by 10.7%and 200 nmol by 38.9%(P<0.05). TSA had no effect on the primary cells. The expression of HER-2 gene of BT474 was down-regulated by 93.9%(P<0.05) in the 5μmol/L group but not in the 1μmol/L group. SAHA significantly affected the pri-mary cells at a concentration of 1μmol/L and reduced the cells at 87.1%at a concentration of 5μmol/L. Seven miRNAs were identified from the miRNA microarray. MiR-762 was used as a basis to identify the changes in miRNA. The miRNA sputum identified by miRNA microarray and qPCR may be associated with the down-regulation of HER-2 by HDAC inhibitors. Conclusion: HDAC inhibitors may down-regulate the expression of HER-2 in breast cancer cells by changing some miRNAs.

Objective:
To systematically evaluate the incidence and influencing factors of depression in family caregivers of Alzheimer's disease (AD) patients, so as to provide the basis for the prevention and treatment of depression among the family caregivers of AD patients.
Methods:
Publications pertaining to depression in family caregivers of AD patients were retrieved from CNKI, Wanfang Data, PubMed and other databases from the time of their establishment to June 15, 2023. The evaluation criteria recommended by the Agency for Healthcare Research and Quality (AHRQ) and the Newcastle-Ottawa Scale were used to assess the quality of cross-sectional and cohort studies, respectively. Stata 16.0 and Revman 5.4 softwares were used to conduct a meta-analysis on the incidence and influencing factors of depression in family caregivers of AD patients. Sensitivity analysis and publication bias assessment were also performed on the results.
Results:
A total of 2 324 articles were retrieved, and ultimately 14 articles were included, with a total sample size of 8 313 individuals. There were 6 high-quality articles and 8 moderate-quality articles. Meta-analysis showed that the incidence of depression in family caregivers of AD patients was 37.5% (95%CI: 30.2%-45.1%). Factors associated with depression included patients' high degree of dementia (OR=1.718, 95%CI: 1.059-2.789), patients' low scores on Activities of Daily Living Scale (OR=1.344, 95%CI: 1.059-1.706), patients' psychobehavioral abnormalities (OR=1.248, 95%CI: 1.155-1.348), long duration of caregiving (OR=1.998, 95%CI: 1.637-2.437), less involvement of other family members in caregiving (OR=1.597, 95%CI: 1.237-2.061), low educational level (OR=1.191, 95%CI: 1.044-1.359), poor caregiving skills (OR=3.060, 95%CI: 2.257-4.149), poor self-rated health (OR=2.536, 95%CI: 1.114-5.771) and social support (OR=0.424, 95%CI: 0.232-0.774). The results of depression incidence demonstrated good stability with no significant publication bias. However, publication bias was observed in the influencing factors for depression, which were patients' high degree of dementia and patients' low scores on Activities of Daily Living Scale.
Conclusions
The incidence of depression in family caregivers of AD patients ranges from 30.2% to 45.1%. It is primarily influenced by the severity of patients' symptoms and ability to perform daily activities, and caregivers' educational level, caregiving skills, health status, caregiving duration and social support.

Objective:To compare the accuracy and generalized robustness of three predictive models of knowledge-based treatment strategies for radiotherapy for optimized model selection.Methods:The clinical radiotherapy plans of 45 prostate cancer (PC) cases and 25 nasopharyngeal cancer (NPC) cases were collected, and analyzed using three models (Z, L and S model), proposed by Zhu et al, Appenzoller et al and Shiraishi et al, respectively, to predict the dose-volume histogram (DVH) of bladder and rectum on PC cases and that of left and right parotid on NPC cases. The prediction error was measured by the difference of area under the predicted DVH and the clinical DVH curves (|V (pre_DVH)-V (clin_DVH)|), where a smaller prediction error implies a greater prediction accuracy. The accuracies of these three models were compared on the single organ at risk (OAR), and the generalized robustness of models was evaluated and compared by calculating the standard deviation of the prediction accuracy on different OAR. Results:For bladder and rectum, the prediction error of L model (0.114 and 0.163, respectively) was significantly higher than those values of Z and S models (≤0.071, P<0.05); for left parotid gland, the predicted error of S model (0.033) did not present significant difference from those values of Z and L models (≤0.025, P>0.05); for right parotid gland, S model (0.033) demonstrated significantly higher prediction error than those of Z and L models (≤0.028, P<0.05). Regarding different OAR, S model showed a lower standard deviation of prediction accuracy when comparing to Z and L models (0.016, 0.018 and 0.060, respectively). Conclusions:In the prediction of DVH in bladder and rectum of PC, Z and S models were more accurate than L model. In contrast, Z and L models demonstrated higher accuracy than S model in the prediction of left and right parotid glands of NPC. In respect to different OAR, the generalized robustness of S model was superior than the other two models.
