The deficiency of fingers due to various reasons leads to a certain degree of loss of full or part hand functions. Physical and mental health of patients are seriously affected, and patients have varying degrees of reduced quality of life. Prosthesis fingers play an important role in completing the body shape and enhancing patients’ self-confidence and self-esteem. However, how to make prosthesis fingers perform coordinated movements and restore complete functions is a crucial problem that urgently needs to be solved. This paper reviews the methods of brain-computer interface controlled fine finger movements and elaborates on the origin, current situation, and advancements of the development of this technology, laying a foundation for subsequent research, with the expectation of helping patients solve the problems arising from the insufficiency or absence of finger functions.

OBJECTIVE:
This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study.
METHODS:
A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants.
RESULTS:
Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m 2) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m 2) and obesity (≥ 28.0 kg/m 2) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m 2 ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses.
CONCLUSION
This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective By establishing a model to screen out patients with potentially large positional deviations based on their abdominal circumference,personalized solutions can be taken to address setup errors in these patients and ensure treatment efficacy.Methods A total of 81 patients treated at Tianjin People's Hospital from May 2021 to June 2023 were selected as the study subjects.The correlations between setup errors in the lateral,longitudinal,and vertical directions and abdominal circumference were analyzed.Subsequently,linear regression was performed for the direction with a significant correlation to abdominal circumference to establish a linear regression model.Finally,the 81 patients were divided into a normal setup group and an abnormal setup group with 0.7 cm as the critical value.A receiver operating characteristic(ROC)curve was plotted,and the maximum Youden index was calculated to determine the optimal cutoff value for identifying patients prone to abnormal setup.Results The correlation analysis of abdominal circumference and setup errors in various directions showed that the correlation coefficient between abdominal circumference and longitudinal direction positioning error was 0.406 2,and the correlation was statistically significant and positively correlated.The correlation coefficients for abdominal circumference and the lateral as well as longitudinal directions were-0.117 5 and-0.067 47,respectively,with P values greater than 0.05,indicating no statistical significance.A linear regression model was established for abdominal circumference and longitudinal direction,and the results showed an R2of 0.165,with a regression coefficient B of 0.008(t=3.951,P<0.01),indicating that the model was well constructed.ROC curve analysis showed an area under the curve of 0.715,with a 95%confidence interval of 0.57-0.86 and a maximum Youden index of 0.478.The corresponding optimal cutoff value was determined to be at 87 cm,with sensitivity at 0.875 and specificity at 0.603.Conclusion The abdominal circumference is significant to diagnose whether the longitudinal setup error is abnormal.Patients with an abdominal circumference greater than 87 cm are more likely to experience abnormal positioning during radiotherapy,which is reflected in the longitudinal setup errors being the largest.It is recommended to provide individualized target area margins for patients with an abdominal circumference greater than 87 cm,or perform daily cone-beam computed tomography to correct setup errors,thereby ensuring target coverage and treatment efficacy.

OBJECTIVES:
Chromosomal abnormalities are the most common cause of spontaneous abortion (SA). This study aims to analyze the association between SA and chromosomal abnormalities in products of conception, and to compare the impact of different pregnancy modes and different numbers of previous abortions on chromosomal abnormalities, providing clinical consulting references.
METHODS:
A total of 1 345 SA patients treated at the Affiliated Women's Hospital of Jiangnan University (Wuxi Maternity and Child Health Care Hospital) between January 2019 and December 2023 were enrolled. According to the mode of conception, patients were divided into 2 groups: a spontaneous pregnancy group (S group, n=1242) and an assisted reproductive technology (ART)-conceived group (ART group, n=103). Based on the number of miscarriages, the S group was further subdivided into a spontaneous sporadic abortion group (S-1 group, n=780) and a spontaneous recurrent abortion group (S-2 group, n=462); the ART group was subdivided into an ART sporadic abortion group (ART-1 group, n=68) and an ART recurrent abortion group (ART-2 group, n=35). Chromosomal microarray analysis (CMA) was performed on products of conception.
RESULTS:
The incidence of numerical chromosomal abnormalities was 56.79% (443/780) in the S-1 group and 52.38% (242/462) in the S-2 group, while the incidence of structural abnormalities was 4.36% (34/780) and 7.36% (34/462), respectively. There was a statistically significant difference in structural abnormalities between the 2 groups (P<0.05). Among the spontaneous pregnancy SA cases, the incidence of numerical abnormalities decreased with increasing numbers of miscarriages, and was significantly lower in the group with ≥4 miscarriages compared to those with 1 or 2 miscarriages (both P<0.05). The incidence of structural abnormalities in groups with 1, 2, 3, and ≥4 miscarriages was 3.46%, 5.65%, 5.88%, and 4.35%, respectively, with no statistically significant differences among groups (all P>0.05). The incidence of pathogenic copy number variants (pCNVs) plus likely pathogenic copy number variants (LP-CNVs) gradually increases in the group with 1-3 miscarriages, and there was a statistically significant difference between the group with 1 miscarriage and the group with 2 miscarriages (P<0.05). In the ART group, the incidence of numerical abnormalities was 47.06% (32/68) in ART-1 and 37.14% (13/35) in ART-2, while structural abnormalities occurred in 2.94% (2/68) and 11.43% (4/35), respectively, with no significant differences between the groups (both P>0.05). There were no statistically significant differences in the incidence of numerical or structural abnormalities between the S-1 and ART-1 groups, or between the S-2 and ART-2 groups (all P>0.05).
CONCLUSIONS
Chromosomal numerical and structural abnormalities are common in SA patients from both spontaneous and ART-conceived pregnancies. Attention should be paid to patients with recurrent miscarriage in genetic investigation.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.
