Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

Objective:To examine the early and midterm surgical outcome of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCA) using revised surgical strategies.Methods:A retrospective analysis of clinical data, surgical methods, and follow-up results was performed of 104 cases of PA/VSD/MAPCA in Department of Cardiovascular Surgery, Guangzhou Women and Children′s Medical Center from January 2017 to September 2022. There were 55 males and 49 females, aged ( M(IQR)) 33.9(84.0) months (range: 0.5 to 209.6 months) at the first surgical procedures. The anatomical classification included 89 cases of type B and 15 cases of type C. The number of major aortopulmonary collateral arteries was 4.2 (3.0) (range: 1 to 8). The Kaplan-Meier method was used for survival estimation. Results:In the first stage of surgery, 50 patients underwent a complete primary repair, 12 patients underwent partial repair, 32 patients underwent palliative right ventricular-pulmonary artery connection, and only 10 patients chose the Blalock-Taussig shunt. There were 10 cases of early death. In the second stage, 14 patients underwent complete repair and 4 patients underwent partial repair with no early death. The interval between the two surgeries was 19 (10) months (range: 9 to 48 months). Finally, during the 40 (34) months follow-up period, a total of 64 patients were complete repair and the right/left ventricular pressure ratio after complete repair was 0.63±0.16 (range: 0.36 to 1.00). Survival analysis showed that survival rates at 1 and 5 years after first-stage surgery were both 89.4% (95% CI: 83.5% to 95.3%). At 28 (34) months (range: 1 to 67 months) of follow-up after complete repair, the survival analysis showed that the survival rates at 1 and 5 years were both 95.2% (95% CI: 89.9% to 100%). Conclusions:Using combined approaches tailored to individual patients and optimized unifocalization strategy, the complete repair rate at one stage and the cumulative complete repair rate at 5 years improved significantly with a lower right/left ventricular pressure ratio and satisfactory early and intermediate survival.

It is difficult to dissolve in water and has poor oral efficacy, but when combined with different substances or combined (forming phospholipid complex), its bioavailability can be improved, so as to improve its pharmacological efficacy.

Objective:To analyze the horizontal scientific research projects from 2015 to 2019 by the provincial Centers for Disease Control and Prevention (CDC) in China, and to compare the regional differences, in order to provide the suggestion on the scientific management of CDC.Methods:The horizontal scientific research projects from 2015 to 2019 were retrospectively analyzed by questionnaire survey. Multiple linear regression models were adopted to examine the trend, and variance analyses were used to test the differences in horizontal scientific research projects among the Eastern, Central, and Western regions.Results:From 2015 to 2019, provincial CDC have received RMB 124.3 million of horizontal scientific research project funds totally, of which 51.9% were funded by enterprises, and 86.9% were undertaken by provincial CDC themselves. There were no statistical significance in the change of research project funds obtained by provincial CDC ( F=0.46, P = 0.764) during this period.The number of horizontal scientific research projects undertook or participated by provincial CDC in the Eastern region were more than that of the Central and Western region ( F = 5.85, P = 0.004; F = 5.03, P = 0.008). Conclusions:The horizontal scientific research projects obtained by the provincial CDC remained stable in recent years while distribution was unbalanced in the region areas. It is suggested to innovate the management mode of scientific research projects with strengthening the trans-agency, trans-department and trans-regional cooperation.
