Objective: To evaluate the suitability of the existing hemolysis rate standards for locally processed red blood cell components by retrospectively analyzing 5-year hemolysis rate data at the end of storage. Methods: A total of 720 blood samples of three types of red blood cell components from our blood station from January 2019 to December 2023 were collected. Parameters included hemoglobin concentration (Hb), hematocrit (Hct), and free hemoglobin concentration (fHb). Hemolysis rate were taken as the control standard of 0.8% in accordance with the national standard. The hemolysis rates were compared against the national standard threshold of 0.8% (GB18469-2012), and annual trends of the detection parameters were observed. Results: The hemolysis rates (x-+s,%) of leukocyte-depleted whole blood at the end of storage were (0.038±0.023 8) in 2019, (0.049±0.039 5) in 2020, (0.043±0.040 7) in 2021, (0.049±0.030 7) in 2022, and (0.058±0.054 8) in 2023, respectively; The hemolysis rates (x-+s" />,%) of leukocyte-depleted suspended red blood cells at the end of storage were (0.093±0.050 2) in 2019, (0.086±0.049 5) in 2020, (0.123±0.072 3) in 2021, (0.122±0.052 1) in 2022, and (0.106±0.058 6) in 2023, respectively; The hemolysis rates (x-+s,%) of washed red blood cells at the end of storage were (0.127±0.038 2) in 2019, (0.150±0.066 5) in 2020, (0.121±0.052 2) in 2021, (0.124±0.038 9) in 2022, and (0.128±0.044 3) in 2023, respectively. Conclusion: Hemolysis rates at the end of blood storage of three red blood cell components were significantly lower than the limits specified in Quality Requirements for Whole Blood and Components (GB18469-2012), as well as standards from the EU, AABB and the United States. The results demonstrate excellent product quality control. A regional internal control standard of <0.2% is proposed for hemolysis rates at the end of storage.

Objective:To retrospectively analyze the clinical and genetic characteristics of six patients with Acromicric dysplasia due to variants of the FBN1 gene. Methods:Six patients who had visited the Affiliated Hospital of Qingdao University between February 2018 and October 2020 were selected as the study subjects. Clinical data of the patients were collected. High-throughput sequencing was carried out. And candidate variants were verified by Sanger sequencing.Results:All of the six patients had presented with severe short stature (< 3 s), brachydactyly, short and broad hands and feet. Other manifestations included joint stiffness, facial dysmorphism, delayed bone age, liver enlargement, coracoid femoral head, and lumbar lordosis. Genetic testing revealed that all had harbored heterozygous variants of the FBN1 gene. Patient 1 had harbored a c. 5183C>T (p.A1728V) missense variant in exon 42, which had derived from his father (patient 2). Patient 3 had harbored a c. 5284G>A (p.G1762S) missense variant in exon 43, which had derived from her mother (patient 4). Patient 5 had harbored a c. 5156G>T (p.C1719F) missense variant in exon 42, which was de novo in origin. Patient 6 had harbored a c. 5272G>T (p.D1758Y) missense variant in exon 43, which was also de novo in origin. The variants carried by patients 1, 3 and 6 were known to be pathogenic. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the FBN1: c. 5156G>T was rated as a pathogenic variant (PS2+ PM1+ PM2_Supporting + PM5+ PP3). Conclusion:All of the six patients had severe short stature and a variety of other clinical manifestations, which may be attributed to the variants of the FBN1 gene.

Objective To evaluate the effect of parasternal intercostal plane block(PIB)on postopera-tive fatigue in elderly patients undergoing off-pump coronary artery bypass grafting(CABG).Methods A to-tal of 111 elderly patients undergoing elective off-pump CABG in Xuzhou Municipal Central Hospital from May 2021 to January 2023 were selected as the study subjects.The patients were divided into the control group(group C,n=55)and PIB group(group P,n=56)by adopting the random number table method.After induction of anesthesia,the patients in the group P received the ultrasound-guided bilateral PIB,and the group C received the equal volume of normal saline at the same site.The incidence rate of postoperative fatigue syn-drome(POFS)on postoperative 1,3,5,7 d and postoperative 8 weeks,NRS scores immediately after extuba-tion and at postoperative 12,24,48 h,postoperative opioid drugs consumption,ICU stay duration,hospitaliza-tion duration and adverse events occurrence were compared between the two groups.Results Compared with the group C,the incidence rates of POFS on postoperative 1,3,5,7 d and postoperative 8 weeks in the group P were significantly decreased,the NRS scores immediately after extubation and at postoperative 12,24 h in the group P were lower,the postoperative opioid drugs consumption were smaller,the ICU stay duration was shorter,and the differences were statistically significant(P＜0.05).The NRS score at postoperative 48 h and hospitalization duration had no statistical differences between the two groups(P＞0.05).No nerve block re-lated adverse events in the patients appeared during the study period.Conclusion The ultrasound guided PIB could effectively reduce the incidence rate of POFS in elderly patients undergoing off-pump CABG,promote the patients'prognosis and improve the recovery quality of the patients.

Objective:To explore the prognosis efficacy of psycho-cardiological therapy and management on patients with coronary atherosclerosis disease (CAD).Methods:This was a clinical randomized controlled study. This study included inpatients with CAD at the cardiology department in Beijing Anzhen Hospital, Capital Medical University from August 2021 to January 2024. The patients enrolled in this study were asked for basic information, and received measurements for depression, anxiety, sleep quality and living quality by the scales of Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder scale-7 (GAD-7), Athens Insomnia Scale (AIS), EuroQol 5-dimension 5-level (EQ-5D-5L) respectively. The patients were randomly grouped into a regular treatment group and a psycho-cardiological treatment group which included WeChat management or antidepressant/antianxiety medical therapy according to the situation. After the patients discharging from hospital for 2, 4, 12, 24, 48, 72, and 96 weeks, professional cardiovascular doctors would follow up by telephone, WeChat, and outpatient department, including scales (2-48 weeks), and cardiac events (2-96 weeks). Kaplan-Meier survival curve and multivariate Cox proportional hazards model were used for analyzing the association between psycho-cardiological treatment and cardiac events.Results:This study recruited a total of 552 patients with CAD, aged 61.0(54.0, 67.0) years, and 379 (68.7%) were male. There were 279(50.5%) in the regular treatment group and 273(49.5%) in the psycho-cardiological treatment group. After treatment for 4, 12 and 48 weeks, the PHQ-9 score in psycho-cardiological was significantly lower than the regular treatment group; After treatment for 12 weeks, the EQ-5D-5L effective value in psycho-cardiological group was higher than the regular treatment group; After treatment for 2, 4, 12, 24 and 48 weeks, the EQ-5D-5L VAS score in psycho-cardiological group was higher than the regular therapy group (all P<0.05). The Kaplan-Meier survival curve showed that, during the different follow-up periods, the rate of cardiac events in psycho-cardiological treatment group was lower than regular treatment group (log-rank P<0.001). The multivariate Cox proportional hazards model adjusted the factor of age, the psycho-cardiological treatment contributed to reducing the cardiac events rate by 80.3% ( HR=0.197, 95% CI: 0.067-0.582, P=0.003). Conclusion:Psycho-cardiological treatment is beneficial for improving psychological stress, living quality, and reducing cardiac events, and helps to improve prognosis and psycho-cardiological rehabilitation in CAD patients.

Hepatic encephalopathy （HE） is a common severe liver disease syndrome in clinical practice and is one of the critical and severe diseases in internal medicine， and more than half of liver failure patients diagnosed with overt HE have a survival time of less than 1 year. A comprehensive analysis of the complex pathogenesis of HE and the development of diagnosis and treatment regimens based on evidence-based medicine are of great importance for alleviating high medical resource consumption， high medical expenses， and high incidence and mortality rates in clinical practice. The latest studies have shown that the intestinal tract and the central nervous system can perform bidirectional continuous interaction and signal transmission and regulate the function of inflammation signals， molecules， cells， and organs， which is known as neuroimmune communication and is highly consistent with the main pathological features of HE. With a focus on the mechanism of neuroimmune communication in HE， this article reviews the association between inflammation signal transduction via the gut-brain axis and neurotransmitter regulation and its role in neuroimmune communication in HE， which provides new ideas for the clinical diagnosis and treatment of HE and the research and development of related drugs.

The management of antibiotic-resistant, bacterial biofilm infections in skin wounds poses an increasingly challenging clinical scenario. Pseudomonas aeruginosa infection is difficult to eradicate because of biofilm formation and antibiotic resistance. In this study, we identified a new benzothiazole derivative compound, SN12 (IC₅₀ = 43.3 nmol/L), demonstrating remarkable biofilm inhibition at nanomolar concentrations in vitro. In further activity assays and mechanistic studies, we formulated an unconventional strategy for combating P. aeruginosa-derived infections by targeting the two-component (Gac/Rsm) system. Furthermore, SN12 slowed the development of ciprofloxacin and tobramycin resistance. By using murine skin wound infection models, we observed that SN12 significantly augmented the antibacterial effects of three widely used antibiotics-tobramycin (100-fold), vancomycin (200-fold), and ciprofloxacin (1000-fold)-compared with single-dose antibiotic treatments for P. aeruginosa infection in vivo. The findings of this study suggest the potential of SN12 as a promising antibacterial synergist, highlighting the effectiveness of targeting the two-component system in treating challenging bacterial biofilm infections in humans.

Autophagy is a highly conserved mechanism for material degradation and recycling in eukaryote cells, and plays important roles in growth, development, stress tolerance and immune responses. ATG10 plays a key role in autophagosome formation. To understand the function of ATG10 in soybean, two homologous GmATG10 genes, namely GmATG10a and GmATG10b, were silenced simultaneously by bean pod mottle virus (BPMV) induced gene silencing. The carbon starvation induced by dark treatment and Western blotting analysis of GmATG8 accumulation level indicated that concurrent silencing GmATG10a/10b resulted in the impairment of autophagy in soybean; disease resistance and kinase assays demonstrated that GmATG10a/10b participated in the immune responses by negatively regulating the activation of GmMPK3/6, indicating that GmATG10a/10b plays a negative regulatory role in immune response in soybean.

Objective:To investigate the influencing factors of headache degree in migraine patients with patent foramen ovale (PFO).Methods:The clinical data of 124 migraine patients with PFO from January 2013 to June 2019 in Dalian Central Hospital Affiliated to Dalian Medical University were retrospectively analyzed. The right-to-left shunt of PFO was assessed by contrast-enhanced transcranial Doppler (c-TCD); the diameter of PFO, length of PFO tunnel and the presence of atrial septal aneurysm (ASA) were detected by transesophageal echocardiography (TEE); the degree of migraine was assessed by headache impact test-6 (HIT-6) scale. The relations between right-to-left shunt volume of PFO, diameter of PFO and degree of migraine were analyzed by Goodman-Kruskal γ test; the relations between the length of PFO tunnel, ASA and degree of migraine were analyzed by Spearman rank correlation analysis.Results:Among the 124 migraine patients with PFO, the c-TCD test result showed that small shunt volume was in 20 cases, medium shunt volume in 31 cases, and large shunt volume in 73 cases. The TEE test result showed that small foramen ovale in 76 cases, medium foramen ovale in 47 cases, and large foramen ovale in 1 case; long tunnel in 57 cases, and short tunnel in 67 cases; without ASA in 91 cases, and with ASA in 33 cases. The HIT-6 score result showed that some influence in 9 cases, significantly influence in 22 cases, and serious influence in 93 cases. The Goodman-Kruskal γ test result showed that right-to-left shunt volume of PFO and diameter of PFO were positive correlation with degree of migraine ( γ = 0.66, P<0.01; γ = 0.38, P<0.05). The Spearman rank correlation analysis result showed that ASA was positive correlation with degree of migraine ( r = 0.18, P<0.05), while the length of PFO tunnel was negative correlation with degree of migraine ( r = -0.23, P<0.05). Conclusions:The right to left shunt amount of PFO, diameter of PFO and the presence of ASA are positive correlation with degree of migraine, while the length of PFO tunnel is negative correlation with degree of migraine.

Objective:To explore the clinical value of continuous renal replacement therapy (CRRT) nursing team in the treatment of critically ill patients.Methods:From October 2019 to October 2020, convenience sampling was used to select 78 critically ill patients admitted to the Intensive Care Unit (ICU) of the Second People's Hospital of Lianyungang as the research object. The patients were divided into the control group and the observation group by random number table method, 39 cases in each group. The control group carried routine nursing, and the observation group implemented high-quality nursing by the CRRT nursing team. The incidence of complications, quality of life, and anxiety and depression scores were compared between the two groups.Results:After intervention, the incidence of complications in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . The quality of life score of the observation group was higher than that of the control group, and the anxiety and depression score was lower than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:High-quality nursing based on the CRRT nursing team can reduce the incidence of complications in critically ill patients in ICU, improve the quality of daily life, and relieve the negative emotions of patients, which has clinical application value.

This study aimed to explore the prevalence and risk factors of cardiovascular disease (CVD) and psychological distress among female scientists and technicians in China. Accordingly, we included scientists and technicians from representative research institutions, medical institutions, colleges, universities, and businesses in China, and the data were collected from July 1, 2019 to March 31, 2021 via online questionnaires. The parameters evaluated in this study included age, sex, marital status, educational background, monthly income, sleep hours, sleep problems, smoking, alcohol consumption, work-related stress, work burnout, cardiovascular symptoms, CVD, family history, and depressive and anxiety symptoms. A total of 14 530 scientists and technicians were included, comprising 7144 men and 7386 women. We found 34.9% men and 16.6% women with CVD, 35.1% men and 21.4% women with depressive symptoms, 28.7% men and 13.8% women with anxiety symptoms, and 22.0% men and 9.5% women with CVD combined with depressive or anxiety symptoms. This study focused on the details of women. Younger women (age≤35 years) had the highest prevalence of depressive symptoms (24.9%), anxiety symptoms (16.2%), and comorbidity (11.2%). It was established that, despite traditional risk factors, unmanageable work burnout, depressive symptoms, and anxiety symptoms were associated with a higher risk of CVD in women; insomnia, overwhelming work stress, unmanageable work burnout, and CVD were linked to a higher risk of depressive symptoms and anxiety; insomnia, overwhelming work stress, and unmanageable work burnout were related to CVD combined with depressive or anxiety symptoms. A bidirectional relationship was noted between CVD and depression or anxiety in female scientists and technicians, and insomnia and overwhelming work stress were positively associated with comorbidity. It is suggested that effective measures should be taken to protect female scientists and technicians from CVD and psychological distress.
