Objective: To analyze population distribution characteristics, routine blood parameters, and independent influencing factors of elevated hemoglobin in overweight red blood cell (RBC) products (suspected polycythemia), and to provide evidence for optimizing pre-donor screening and improving component quality and clinical transfusion safety. Methods: A total of 82 overweight RBC product cases verified by the quality control department from 2021 to 2025 were retrospectively enrolled. Product information, donor demographic data and blood disposal outcomes were statistically described. Correlation analysis and multiple linear regression were performed on 55 samples with complete routine blood test data. Results: Overweight products were mainly leukocyte-filtered suspended red blood cells (70.73%), with 2 U specifications accounting for 56.10%. Most donors were young and middle-aged males (96.34% male, 87.80% aged 18-49 years). Hb, RBC count and Hct in the overweight group were significantly higher than those in the control group (all P<0.001), with strong correlations among the three indicators. History of high-altitude exposure was an independent risk factor for elevated Hb (B=14.517, P=0.020). Higher Hb level was associated with higher discard rates of blood products for clinical use. Conclusion: Overweight RBC products result from synchronous abnormal elevation of Hb, RBC count and Hct among donors. Young and middle-aged males and those with a history high-altitude exposure are high-risk populations. Current donor screening only sets the lower limit of Hb without unified upper limits for RBC-related parameters. Incorporating upper-limit screening for Hb/Hct and standardized inquiry for high-altitude exposure to routine pre-donation assessment may reduce overweight events of RBC products, decrease blood discard rates and enhance transfusion safety. It also offers practical in-sights for implementing the 2026 edition of the Technical Operating Procedures for Blood Stations.

Primary central nervous system lymphoma (PCNSL) is a rare highly aggressive brain tumor originating from the extranodal sites, with a low 5-year overall survival rate. Some patients may have drug resistance or relapse, the therapeutic regimens based on high-dose methotrexate is insufficient to meet the clinical treatment needs. With the in-depth study of characteristics of lymphoma-related genes and immune microenvironment, new pathways continue to emerge, including Bruton tyrosine kinase inhibitors, immune preparations such as lenalidomide, anti-programmed death receptor-1 antibodies, chimeric antigen receptor T-cell therapy, etc. This review focuses on the progress of targeted drugs and immunotherapy for PCSNL.

Objective:To investigate the expression and significance of endoplasmic reticulum stress apoptosis pathway related proteins in renal cortex of rats with chronic fluorosis.Methods:Twenty four healthy SD rats were divided into 4 groups (6 rats/group, half male and half female) according to their body mass (100 - 120 g) by random number table method, rats in control group drank tap water (fluoride content < 0.5 mg/L), and in low, medium and high fluoride groups drank tap water with fluoride content (sodium fluoride) of 10, 50 and 100 mg/L, respectively. After 180 days of feeding, dental fluorosis was examined, 24-hour urine sample was collected and the content of fluoride in urine was detected by fluoride ion selective electrode method. Renal tissue was taken after anesthesia, and the pathological changes of renal cortex were observed by hematoxylin-eosin (HE) staining. The expressions of endoplasmic reticulum stress apoptosis pathway related proteins [inositol-requiring enzyme 1α (IRE1α), apoptosis signal-regulating kinase 1 (ASK1), C-Jun N-terminal kinase (JNK) and phosphorylated JNK (P-JNK)] were determined by immunohistochemical staining in rat renal cortex.Results:No dental fluorosis was found in control group. The incidence of dental fluorosis in low, medium and high fluoride groups were 2/6, 5/6 and 6/6, respectively. Compared with control group [(5.707 ± 1.190) mg/L], the urinary fluoride in low, medium and high fluoride groups [(17.028 ± 3.006), (34.378 ± 12.045), (94.759 ± 31.773) mg/L] was significantly higher ( P < 0.05), and the urinary fluoride in high fluoride group was higher than that in low and medium fluoride groups ( P < 0.05). HE staining showed that, compared with control group, the cell volume of renal tubules and glomeruli in medium and high fluoride groups increased, the cells arranged closely, and the eosinophilia of the cytoplasm increased. The immunohistochemical staining results showed that there was no significant difference in the expression of JNK protein in rat renal cortex between control group and low, medium and high fluoride groups ( F = 0.07, P > 0.05). The expressions of IRE1α, ASK1 and P-JNK proteins in rat renal cortex in high fluoride group were higher than those of control, low and medium fluoride groups ( P < 0.05), and the expressions of IRE1α and ASK1 proteins in medium fluoride group were significantly higher than those in control and low fluoride groups ( P < 0.05). Conclusion:Long-term excessive fluoride intake can lead to renal cortex injury in rats, and the mechanism of injury may be related to the activation of IRE1α-ASK1-JNK endoplasmic reticulum stress apoptosis pathway.

Diffuse large B-cell lymphoma (DLBCL) is a group of heterogeneous diseases, and further classification is of great value for prognostic stratification. In recent years, some subtypes with poor prognosis have been recognized, such as "double-hit" lymphoma or "double-expressing" lymphoma. In addition, the new molecular classification provides a new perspective for the accurate diagnosis and prognosis stratification of DLBCL. The mutation and deletion of p53 gene are high risk factors in the traditional sense of DLBCL, while with the application of the next generation sequencing and other technologies, the influence of more accurate gene mutation or deletion on prognosis and its prognostic value in new cell molecular subtypes still need to be further confirmed. This paper reviews the progress of cell phenotypes and molecular subtypes as well as p53 gene abnormalities in the prognosis of DLBCL.

Objective:To investigate the clinicopathological and molecular biological characteristics of patients with plasma cell tumor.Methods:The data of bone marrow fluid, bone marrow tissue, peripheral blood and urine specimens of 84 patients with plasma cell tumor from January 2016 to October 2018 in Shanxi Provincial People's Hospital were collected. Bone marrow fluid was examined by using bone marrow smear, karyotype analysis, fluorescence in situ hybridization (FISH), immunophenotyping, and next-generation sequencing (NGS). In addition to the observation of cell morphology, peripheral blood together with urine specimens was also determined by using immune-fixation electrophoresis and free light chain examination. Bone marrow tissue was used to observe the structure and fibrosis of bone marrow, and relevant histochemistry and immunohistochemistry was also performed.Results:Among 84 patients with plasma cell tumor, 2 patients (2.4%) were monoclonal gammopathies of un-determined significance (MGUS), 78 patients (92.8%) were multiple myeloma (MM) (38 cases were IgG Kappa type, 33 cases were IgG Lambda type, 2 cases were IgA Kappa type, 1 case was IgA Lambda type, 3 cases were light chain type, 1 case was non-secretory type), 3 cases (3.6%) were Waldenstrom macroglobulinemia (WM), and 1 case (1.2%) was non-secretory myeloma (NSM). The proportion of abnormal plasma cells detected by bone marrow smear was 0.132-0.676 in 81 patients, and the proportion of abnormal monoclonal plasma cells detected by flow cytometry (FCM) was 1.1%-52.4% in 79 patients. Immunohistochemistry and FCM detection of bone marrow showed positive or weak positive results of CD38 and CD138. Complex karyotype was rare in karyotype analysis. FISH examination showed IGH isolation in 24 patients (28.6%) and gene detection showed 1 case was positive IGH-CCND1 and 1 case was positive IGH-MAF; 1 case of free light chain examination was positive. The positive rate of NGS was lower.Conclusion:Most plasma cell tumors are IgG type, followed by IgA type. Light chain type of plasma cell tumors is rare, and IgM type and non-secretory type are extremely rare. The morphological manifestations of bone marrow smear cytology in different clone types are different.

Objective To explore the effect of nursing intervention based on the transtheoretical model and stages of change on breastfeeding knowledge, self-efficacy, and duration of breastfeeding in newly born pregnant women, aimed to provide reference for breastfeeding behavior health education model for pregnant women. Methods The 130 primiparas who came to the hospital graded a class- three of Shanxi Province for perinatal examination were selected as the research subjects from May to June in 2017 , they were divided into test group and control group by random digits table method. In the control group, the normal breastfeeding health guidance was carried out in the three stages of prenatal, hospitalized and after discharge. The test group divided the primipara from the beginning of pregnancy to 6th months postpartum period into 5 stages according to transtheoretical model and stages of change. The new strategy of breastfeeding should be formulated and implemented according to different stages and behavior changing processes.
