In 2022， Hainan provincial government launched the project for the prevention and control of viral hepatitis with the goals of a hepatitis B screening rate of 90%， a diagnostic rate of 90%， and a treatment rate of 80% among people aged 18 years and above by the year 2025， and the main intervention measures include population-based prevention， case screening， antiviral therapy， and health management. As of December 31， 2024， a total of 6.875 million individuals in the general population had been screened for hepatitis B， with a screening rate of 95.6%. A total of 184 710 individuals with positive HBsAg were identified， among whom 156 772 were diagnosed through serological reexamination， resulting in a diagnostic rate of 84.9%. A total of 50 742 patients with chronic hepatitis B were identified， among whom 42 921 had hepatitis B-specific health records established for health management， with a file establishment rate of 84.6%. A total of 31 553 individuals received antiviral therapy， with a treatment rate of 62.2%. A total of 2.503 million individuals at a high risk of hepatitis C were screened， among whom 4 870 tested positive for HCV antibody and 3 858 underwent HCV RNA testing， resulting in a diagnostic rate of 79.2%， and 1 824 individuals with positive HCV RNA were identified， among whom 1 194 received antiviral therapy， with a treatment rate of 65.5%. In addition， 159 301 individuals with negative HBsAg and anti-HBs and an age of 20 — 40 years were inoculated with hepatitis B vaccine free of charge. Through the implementation of the project for the prevention and control of viral hepatitis， a large number of hepatitis patients have been identified， treated， and managed in the province within a short period of time， which significantly accelerates the efforts to eliminate the crisis of viral hepatitis.

Direct antiglobulin test (DAT), also known as Coomb's test, is a method used in blood immunology to detect whether the surface of red blood cells is sensitized by immunoglobulin or complement. It is mainly used in the diagnosis of autoimmune hemolytic anemia (AIHA), neonatal hemolytic anemia, hemolytic transfusion reaction and blood matching during blood transfusion. DAT positive has always been the focus of researchers, because it has an important impact on the efficacy of blood transfusion. In recent years, there has been extensive research on the identification of DAT positivity types and the distribution characteristics of diseases in clinical patients, and the study on hemolytic disease of the newborn has also been popular. However, the transfusion safety of DAT-positive blood donors has been a hot topic in the field of blood transfusion for many years. Moreover, there is no clear requirement from the state on the handling of DAT-positive blood and whether DAT-positive blood donors should be deferred from donation. Therefore, this article reviews the serological studies on DAT immunotyping and IgG subtype typing of voluntary blood donors, as well as the impact of DAT-positive blood on blood transfusion safety, in order to provide references for the blood issuance strategy of DAT-positive blood and whether DAT-positive blood donors should be deferred.

Cluster of differentiation 36 (CD36) is a highly glycosylated double transmembrane glycoprotein, which is involved in the inflammatory response and immune regulation of the body. It plays a key role in mediating the mechanism of immune-related blood transfusion reactions and regulating the function of immune cells. It has an important impact on blood transfusion safety and has become a current research hotspot. This article reviews and comprehensively analyzes the research progress of the specific role of CD36 in the immune response of blood transfusion and its regulatory mechanism at home and abroad. Combined with clinical cases and experimental data, the pathophysiological mechanism of CD36 in immune response and its immune-mediated blood transfusion safety issues are reviewed. It is expected to provide new theoretical support and practical guidance for the field of blood transfusion safety and promote the further development of blood transfusion medicine.

Objective: To evaluate the impact of comprehensive nursing based on the behavioral goal attainment model on the clinical intervention effect among elderly female patients with stress urinary incontinence (SUI), so as to provide a basis for optimizing the nursing strategies for patients with SUI and improving their quality of life. Methods: A total of 190 elderly female patients with SUI who were treated in the Department of Gynecology of the First Hospital of Jilin University from January 2023 to August 2024 were selected and randomly divided into the intervention group and the control group. The control group received routine nursing care, while the intervention group received comprehensive nursing based on the behavioral goal attainment model. The 1-hour pad test was used to assess urinary incontinence symptoms. The bio-electrical stimulation feedback instrument was employed to detect the electromyogram (EMG) values in the pre-resting stage and slow-muscle stage for evaluating pelvic floor function. The bladder function scale was utilized to evaluate bladder function. The Chinese version of urinary incontinence ego-efficacy rating scales and incontinence quality of life assessment scale (IQOL) were used to assess self-efficacy and quality of life. The data on intervention compliance and nursing satisfaction were collected by a questionnaire survey. The differences between the two groups before and after the intervention were compared using the analysis of variance for repeated-measures data to evaluate the intervention effect. Results: There were 95 cases in the control group and 95 cases in the intervention group, with median ages were 64.00 (interquartile range, 23.50) and 64.50 (interquartile range, 19.50) years, respectively. The proportion of patients with cesarean section as the last delivery method was 21.05% in the control group and 12.63% in the intervention group. The proportion of patients with moderate disease severity was 67.36% in the control group and 58.95% in the intervention group. There were no statistically significant differences in age, body mass index, number of pregnancies, number of deliveries, marital status, educational level, mode of last delivery and severity of the disease between the two groups of patients (all P>0.05). The analysis of variance of repeated-measures data showed that there were significant interactions between time and group for the urine leakage volume in the 1-hour pad test, the EMG values in the pre-resting stage, the EMG values in the slow-muscle stage, the scores of the bladder function, the self-efficacy scores, and the IQOL scores (all P<0.05). After 12 weeks of intervention, the EMG values in the slow-muscle stage, the scores of the bladder function, the self-efficacy scores, the IQOL scores in the intervention group were higher than those in the control group, while the urine leakage volume in the 1-hour pad test and the EMG values in the pre-resting stage in the intervention group were lower than those in the control group (all P<0.05). The good compliance rate of intervention and the satisfaction rate of nursing in the intervention group were higher than those in the control group (83.16% vs. 60.00%, 90.53% vs. 75.79%, both P<0.05). Conclusion Comprehensive nursing based on the behavioral goal attainment model can improve urinary incontinence symptoms, pelvic floor function, bladder function, self-efficacy, quality of life, and intervention compliance of elderly female patients with SUI.

Chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH) are both chronic progressive respiratory diseases that cannot be completely cured. COPD is characterized by irreversible airflow limitation, chronic airway inflammation, and gradual decline in lung function, whereas PH is characterized by pulmonary vasoconstriction, remodeling, and infiltration of inflammatory cells. These diseases have similar pathological features, such as vascular hyperplasia, arteriolar contraction, and inflammatory infiltration. Despite these well-documented observations, the exact mechanisms underlying the occurrence and development of COPD and PH remain unclear. Evidence that mitochondrial dynamics imbalance is one major factor in the development of COPD and PH. Mitochondrial dynamics is precisely regulated by mitochondrial fusion proteins and fission proteins. When mitochondrial dynamics equilibrium is disrupted, it causes mitochondrial and even cell morphological dysfunction. Mitochondrial dynamics participates in various pathological processes for heart and lung disease. Mitochondrial dynamics may be different in the early and late stages of COPD and PH. In the early stages of the disease, mitochondrial fusion increases, inhibiting fission, and thereby compensatorily increasing adenosine triphosphate (ATP) production. With the development of the disease, mitochondria decompensation causes excessive fission. Mitochondrial dynamics is involved in the development of COPD and PH in a spatiotemporal manner. Based on this understanding, treatment strategies for mitochondrial dynamics abnormalities may be different at different stages of COPD and PH disease. This article will provide new ideas for the potential treatment of related diseases.

Objective:To explore the mechanism by which Pien Tze Huang improves liver Kupffer cell damage induced by lipopolysaccharide (LPS) by regulating the expression of miR-155.Methods:LPS induced liver Kupffer cells to establish a cell injury model to simulate septic liver injury. RT-qPCR was used to detect the expression of miR-155 in damaged cells, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the inflammatory response and apoptosis of damaged cells. Then we treated LPS-induced Kupffer cells with Pien Tze Huang at different concentrations (0 mg/L, 5 mg/L, 10 mg/L and 15 mg/L), and detected the expression of miR-155 in the cells, the inflammatory response of the cells and Apoptosis rate. MiR-155 was silenced in the cell injury model, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the effect of miR-155 on inflammatory response and apoptosis of model cells. Overexpression of miR-155 in damaged cells treated with Pien Tze Huang was used to detect changes in cellular inflammatory response and apoptosis. Data are expressed in the form of mean ± standard deviation, and each group of data is analyzed using t test or one-way analysis of variance.Results:In the LPS-induced liver Kupffer cell injury model, the expression of miR-155 was significantly increased ( P<0.05), the expression levels of pro-inflammatory factors IL-6 and TNF-α were significantly increased, and the anti-inflammatory factor IL-10 was significantly increased. was inhibited ( P<0.05), and the cell apoptosis rate was significantly increased ( P<0.05). After Pien Tze Huang treatment, the expression of miR-155 in damaged liver cells was inhibited ( P<0.05), the levels of cellular inflammatory factors IL-6 and TNF-α were inhibited, and the expression of anti-inflammatory factor IL-10 was promoted ( P<0.05). Inhibit cell apoptosis ( P<0.05). Silencing miR-155 reduced the inflammatory response and apoptosis rate of cells ( P<0.05). Overexpression of miR-155 can reverse the effect of Pien Tze Huang on liver cell injury ( P<0.05). Conclusions:In the model of LPS-induced liver Kupffer cell injury, Pien Tze Huang can inhibite the inflammatory response and apoptosis of cells by inhibiting the expression of miR-155.

AIM:To investigate whether the expression of perilipin 2(PLIN2)in renal tubular cells could predict a decline in renal function in diabetic kidney disease(DKD)patients,and to explore the potential mechanisms in-volved in renal tubular cell injury induced by PLIN2 during the progression of DKD.METHODS:Control individuals(n=12)and DKD patients(n=51)were enrolled in this retrospective cohort study.Demographic and laboratory data were col-lected.A simplified linear mixed-effects model was applied to assess the estimated glomerular filtration rate(eGFR)slope.The relationship between PLIN2 and renal function decline in DKD patients was predicted by Spearman correlation analysis and a generalized linear model.BKS-db/db diabetic mice and streptozotocin-induced diabetic mice were used.Primary renal tubular cells were treated with glucose and transfected with small interfering RNA or plasmid.Western blot-ting and immunofluorescence staining were used to detect PLIN2 expression.Lipid droplets were stained with oil red O.The oxygen consumption rate(OCR)of mitochondria was measured using an extracellular flux analyser.RESULTS:The expression of PLIN2 was markedly higher in the tubules of DKD patients than in those of control subjects.After 24(12,39)months of follow-up,the eGFR slope of DKD patients was-7.42(-19.77,-2.09)mL/(min·1.73 m2·year).An in-crease in the baseline percentage of PLIN2-positive tubules was significantly associated with the eGFR slope during the fol-low-up period[hazard ratio(HR)=1.90,95%confidence interval(CI):1.00～3.58],indicating that tubular PLIN2 could predict a decrease in renal function in DKD patients.Both the accumulation of lipid droplets and the expression of PLIN2 were markedly greater in the tubules of diabetic mice than in those of control mice.Glucose treatment induced lipid droplet accumulation and PLIN2 expression in renal tubular cells.Knockdown of PLIN2 significantly alleviated glucose-in-duced lipid droplet accumulation,whereas PLIN2 overexpression aggravated glucose-induced lipid droplet accumulation.The decrease in mitochondrial OCR in renal tubular cells induced by glucose treatment was alleviated after PLIN2 knock-down.However,overexpression of PLIN2 directly decreased the mitochondrial OCR.CONCLUSION:The PLIN2 ex-pression in tubules predicts a decline in renal function in patients with DKD.The PLIN2 suppresses mitochondrial aerobic respiration and contributes to the accumulation of lipid droplets in renal tubular cells to promote the progression of DKD.

Objective To explore the risk factors of perioperative blood transfusion in patients with recurrent nasopharyngeal carcinoma undergoing nasal endoscopic surgery,and construct a nomogram predic-tion model.Methods A retrospective analysis was conducted on the clinical data of 262 patients who un-derwent the nasal endoscopic surgery from January 2021 to May 2023.The patients were divided into two groups according to perioperative blood transfusion or not:non-transfusion group and transfusion group.Uni-variate and multivariate logistic regression were conducted to identify independentrisk factors of perioperative blood transfusion,and a nomogram prediction model was developed.The receiver operating characteristic(ROC)curve was drawn,and the area under the curve(AUC)was calculated.Results The incidence of blood transfusion in patients with recurrent nasopharyngeal carcinoma undergoing nasal endoscopic surgery was 46(17.6％).Multivariate logistic regression analysis revealed that preoperative hemoglobin level 70 to＜100 g/L(OR=6.178,95％CI 2.271-16.805,P＜0.001),preoperative albumin level 25 to＜35 g/L(OR=2.126,95％CI 1.021-4.424,P=0.044),and classification of surgery grade Ⅲ or Ⅳ (OR=4.725,95％CI 1.634-13.584,P=0.004)were independent risk factors for predicting perioper-ative blood transfusion in patients with recurrent nasopharyngeal carcinoma undergoing nasal endoscopic sur-gery.The AUC of the nomogram model was 0.769(95％CI 0.701-0.838),the sensitivity was 67.6％,and the specificity was 76.1％.Conclusion Preoperative hemoglobin level 70 to＜100 g/L,preoperative albumin level 25 to＜35 g/L,and classification of surgery grade Ⅲ or Ⅳ are independent risk factors of perioperative blood transfusion in patients with recurrent nasopharyngeal carcinoma undergoing nasal endo-scopic surgery.The nomogram model established based on the above risk factors has good predictive ability for perioperative blood transfusion.
