In maintaining normal function and activation processes, glycolysis, lipid metabolism, and amino acid metabolism play key roles in the energy demand of platelets. In the resting state, platelets primarily rely on glycolysis and aerobic oxidation to generate energy. Upon activation, platelets preferentially utilize glycolysis, as it can more rapidly provide the required ATP. In addition to glycolysis, platelets can also utilize glycogen and fatty acids as additional energy sources. The ATP provided by fatty acid oxidation is crucial for platelet activation. Additionally, during platelet storage, distinctive changes in energy metabolism occur. In the early stages of storage, platelets primarily rely on glycolysis and the pentose phosphate pathway (PPP) to generate energy. In the mid-storage phase, there is an increase in tricarboxylic acid cycle (TCA) metabolism. In the later stages of storage, cellular metabolism gradually declines. The regulation and flexibility of these metabolic pathways play a critical role in the survival and function of platelets in different states.

Objective: To accurately determine the ABO blood group of samples exhibiting forward/reverse grouping discrepancies by combining first-generation (Sanger) and third-generation (long-read) sequencing technologies. Methods: Five samples with ABO forward/reverse grouping discrepancies were selected. Serological testing was conducted using automated blood typing instruments and the tube method. Genotyping was conducted using both Sanger and long-read sequencing technologies. Results: Sanger sequencing identified specific genetic mutations in two samples, with genotypes of ABO BA. 04/ABO O.01.01 and ABO B3.05/ABO O.01.02. Further analysis with long-read sequencing revealed specific mutations in the +5.8kb region of intron 1 (c.28+5885C>T and c.28+5861T>G) in three samples where mutations were not detected by Sanger sequencing. These mutations affect the expression of the ABO antigens and are likely responsible for the ABO subgroup phenotypes. Conclusion: The integration of Sanger and long-read sequencing technologies effectively identifies genetic variations causing ABO subtypes, providing a scientific basis for enhancing clinical transfusion safety and ensuring accurate blood group determination.

Objective: To analyze changes in Rh system antibodies among antibody-positive patients and evaluate the efficacy of Rh phenotype-matched electronic cross-matching (hereinafter referred to as Rh-ECM). Methods: A retrospective analysis was performed on antibody screening data of 48 254 patients in our hospital from December 2023 to March 2025. The antibody screening results were compared between the pre-application phase (n=46 346, control group) and post-application phase (n=48 254, experimental group) of Rh-ECM technology, focusing on the changes in the proportion of Rh system antibodies, with statistical analysis conducted using SPSS 26.0 software. Meanwhile, the initial and re-examination situations of Rh antibody in the antibody screening of approximately 20 000 person-times each before (June 2019 to June 2020, n=21 048) and after (July 2020 to April 2021, n=20 965) of Rh-ECM were evaluated to explore the influence of Rh-ECM on the detection rate of Rh antibody. Results: After Rh-ECM implementation, 345 positive cases (0.7%) (345/48 254) were detected among 48 254 patients, primarily consisting of mns system antibodies (128 cases, 37.1%) (128/345) and rh system antibodies (95 cases, 27.5%) (95/345). Before Rh-ECM implementation, 199 positive cases (0.4%) (199/46 346) were detected among 46 346 patients, with rh system antibodies accounting for 97 cases (48.7%) (97/199). The difference in the composition ratio of Rh antibodies between the two phases was statistically significant (P<0.001), and the relative risk ratio of Rh antibody detection after Rh-ECM implementation was 56.5% compared to before. Another set of data analysis showed that before Rh-ECM, there were 37 cases with initial positive results and 8 cases with re-examination positive results; after Rh-ECM, these numbers were 44 and 2 respectively There was a statistically significant difference in the re-examination positive rate of Rh antibodies between the two stages (P<0.05). Conclusion: The implementation of Rh-ECM technology significantly reduced the proportion of Rh system antibodies among patients with positive antibody screening results. This suggests that Rh-ECM can effectively reduce the detection rate of Rh antibodies, which may be related to the reduced risk of antibody production due to Rh-matched transfusion, thus improving transfusion safety. Therefore, Rh-ECM is worthy of broader promotion in clinical transfusion testing.

Mucin16 (MUC16), also known as carbohydrate antigen 125 (CA125), is a glycoprotein antigen that can be recognized by the monoclonal antibody OC125 detected from epithelial ovarian carcinoma antigen by Bast et al in 1981. CA125 is not present in normal ovarian tissue but is usually elevated in the serum of epithelial ovarian carcinoma patients. CA125 is the most commonly used serologic biomarker for the diagnosis and recurrence monitoring of epithelial ovarian carcinoma. MUC16 is highly expressed in varieties of tumors. MUC16 can interact with galectin-1/3, mesothelin, sialic acid-binding immunoglobulin-type lectins-9 (Siglec-9), and other ligands. MUC16 plays an important role in tumor genesis, proliferation, migration, invasion, and tumor immunity through various signaling pathways. Besides, therapies targeting MUC16 have some significant achievements. Related preclinical studies and clinical trials are in progress. MUC16 may be a potential novel target for tumor therapy. This article will review the mechanism of MUC16 in tumor genesis and progression, and focus on the research actuality of MUC16 in tumor therapy. This article also provides references for subsequent tumor therapy studies targeting MUC16.

Objective: To investigate the influencing factors of nosocomial infections among patients undergoing radiotherapy, so as to provide insights into nosocomial infection control among radiotherapy patients. Methods: The malignant tumor patients receiving radiotherapy in Yiwu Central Hospital from 2019 to 2020 were selected. Their demographic features, radiotherapy and nosocomial infections were collected through the eletronic medical records. The factors affecting nosocomial infections were identified among radiotherapy patients using a multivariable logistic regression model. Results: Totally 553 malignant tumor patients receiving radiotherapy were enrolled, including 268 men ( 48.46% ) and with a mean age of ( 60.31±13.66 ) years. The mean duration of hospital stay was ( 28.67±14.32 ) days, and the mean radiotherapy cycle was ( 3.63±1.89 ) weeks. A total of 46 patients were detected with nosocomial infections, with prevalence of 8.32%. The top three sites with the highest prevalence of nosocomial infections included the lower respiratory tract ( 14 cases, 30.43% ), oral cavity ( 10 cases, 21.74 ) and urinary tract ( 8 cases, 17.39% ), and 42 bacterial strains were isolated, with Gram-negative bacteria as the predominant strains ( 25 strains, 59.52% ). Multivariable logistic regression analysis showed that radiotherapy cycle of 4 weeks and longer ( OR=3.857, 95%CI: 1.896-7.846 ), radiotherapy exposure ( OR=3.254, 95%CI: 1.561-6.783 ), arteriovenous catheterization ( OR=2.165, 95%CI: 1.144-4.098 ), urinary tract intubation ( OR=6.028, 95%CI: 1.841-19.734 ) and poor nutritional status ( OR=3.933, 95%CI: 1.493-10.360 ) were associated with nosocomial infections among radiotherapy patients. Conclusion Radiotherapy cycle, exposure to radiotherapy, arteriovenous catheterization, urinary tract intubation and poor nutritional status are factors affecting nosocomial infections among radiotherapy patients.

Detection of prostate specific antigen (PSA) is the most commonly used screening method for prostate cancer. However, many studies have found that the false positive rate and false negative rate of PSA detection for prostate cancer screening are very high, which easily leads to the overuse of PSA detection. Autoantibodies appear at the early stage of cancer, accompany the occurrence and development of prostate cancer. Autoantibodies have a long half-life and are easy to detect. Existing studies have found that autoantibodies can be used in the diagnosis of prostate cancer, and correlated with some prognostic indicators such as Gleason grade and overall survival (OS) of prostate cancer patients. This paper summarized 8 studies on the role of single autoantibody in the diagnosis and prognosis of prostate cancer. Most of the reported single autoantibodies have better diagnostic performance than PSA, and combined application could improve the diagnostic performance. Some autoantibodies are related to a poor prognosis of prostate cancer.

Objective:To investigate the relevant situation of the emergency departments (ED) of general hospitals at all levels in Zhejiang Province participating in the prevention and control of Corona Virus Disease 2019 (COVID-19), and to provide a reference for further improving the capacity of emergency services.Methods:A multi-center cross-sectional investigation study was jointly initiated by the Zhejiang Provincial Emergency Medicine Quality Control Center, the Emergency Medicine Branch of Zhejiang Medical Association, and the Emergency Physicians Branch of Zhejiang Medical Doctors Association. Before investigation, experts were organized to develop a special questionnaire. Then the ED of general people's hospitals or Chinese Medicine hospitals at the county/district-level or above were included and their participations in the prevention and control of COVID-19 epidemic between March 9, 2020 and March 15, 2020 were investigated. The collected information included: basic information of the hospitals; participation of ED in fever clinics; the number of COVID-19 patients admitted to ED; the situation of ED support to the anti-epidemic front-line; and the epidemic prevention facilities of ED, and the early supply of medical protective equipments.Results:A total of 181 hospitals from 11 prefectures and cities across the province were finally included, including 52 (28.7%) Grade-A tertiary hospitals, 45 (24.9%) Grade-B tertiary hospitals, 64(35.4%) Grade-A secondary hospitals, and 20 (11.0%) Grade-B secondary or lower hospitals. Among them, 93 (51.4%) were COVID-19 designated hospitals, and 49 (27.1%) had the ability to detect COVID-19 nucleic acid; 177 (97.8%) set up independent fever clinics and 33 (18.6%) were managed by ED alone or mainly. The medical staffs of 65 (36.7%) fever clinics were all or mainly from ED. A total of 213 cases of COVID-19 were received/treated in 40.3% ED, accounting for 17.3% of the total number of cases in Zhejiang Province. A total of 3 848 doctors and nurses supported the front-line of epidemic prevention, of them, 253 supported Hubei Province (accounting for 12.5% ??of the total number). There were 68.5% and 76.8% ED having spare separate clinic and ordinary rescue single room to deal with the COVID-19. In addition, at the early days of anti-epidemic, more than 50% ED were in short supply or even had no medical protective equipment.Conclusions:The ED of Zhejiang Province plays an important role and has made a great contribution to the prevention and control of the COVID-19 epidemic. It is necessary to improve the conditions of ED to effectively respond to the prevention and control of daily infectious diseases.

OBJECTIVE To evaluate the clinical outcome of submucosal inferior turbinectomy and outfracture surgery of inferior turbinates. METHODS All patients receiving two different operations were measured by acoustic rhinometry and questionnaire of QOL at preoperative 1 week and postoperative 12 months, seperately. RESULTS Forty-seven patients with inferior turbinate hypertrophy were enrolled in this study. Evaluation of SNOT-20 discovered both surgeries could improve patients' QOL with similar outcome. Preoperative '5 important items' in patients with inferior turbinate hypertrophy were 'lack of a good night's sleep', 'need to blow nose', 'thick nasal discharge', 'fatigue' and 'dizziness'. Postperative '5 important items' were 'postnasal discharge', 'runny nose', 'sneezing', 'reduced concentration' and 'reduced productivity'. Both surgeries could make acoustic rhinometry parameters change obviously, such as minimal cross-sectional area, 0-5 cm nasal volume(NV) and 2-5 cm NV. Furthermore, submucosal inferior turbinectomy produced more volume in nasal cavity than outfacture surgery, (7.28±2.01)cm3 vs (6.01±1.22)cm3, (5.99±1.87)cm3 vs (4.23±1.08)cm3(P<0.05), seperately. There was no correlation between the data of SNOT-20 and acoustic rhinometry. CONCLUSION We recommend outfracture surgery of inferior turbinate as the preferred surgical choice for patients with mild inferior turbinate hypertrophy.

Objective To explore the effect of comprehensive management of cardiac rehabilitation on the quality of life of patients after percutaneous coronary intervention(PCI). Methods A total of 60 patients with PCI were randomly divided into the rehabilitation group and the control group with 30 cases each by convenience sampling method. The control group received routine treatment and nursing care of postoperative PCI, and the rehabilitation group received cardiac rehabilitation management on the basis of the control group, including training guidance, management of double heart psychological intervention, nutritional intervention diet guidance, evidence-based medicine, and set up system etc. The Hospital Anxiety and Depression Scale(HADS) score, 6 minutes walking distance (6MWD), coronary heart disease risk factors and Seattle Angina Score (SAQ score) were observed at 6 months after PCI. Results HADS score anxiety rate, depression rate, anxiety and depressive state at 6 months after PCI was 10.0%(3/30), 10.0%(3/30), 0 respectively in the rehabilitation group, and 33.3%(10/30), 36.7%(11/30), 13.3%(4/30) in the control group respectively, and there was significant difference between 2 groups (χ2=4.504, 5.963, 1.071. all P<0.05). 6MWD was (451 ± 48) m in the rehabilitation group and (402 ± 42) m in the control group, and there was significant difference between 2 groups (t=6.155, P=0.022). Compared two groups of coronary heart disease risk factors control level: there was significant difference in total cholesterol, triglycerides, high density lipoprotein cholesterol, low density lipoprotein cholesterol, glycosylated hemoglobin, body mass index, systolic pressure, diastolic pressure(t=-2.927-5.981, P<0.01 or 0.05). SAQ score in physical limitation, angina stability , angina pectoris, treatment satisfaction, disease awareness scores were (73.79 ± 6.04), (80.35 ± 7.63), (75.31 ± 8.11), (80.23 ± 5.44), (76.59 ± 14.29) points in the rehabilitation group, and (53.19 ± 5.13), (65.87 ± 18.85), (64.41 ± 6.31), (70.49 ± 8.01), (45.83 ± 8.65) points in the control group, there were significant differences between 2 groups (t=-21.630-18.959, all P<0.01). Conclusions The comprehensive management of cardiac rehabilitation alleviates the anxiety and depression of patients after PCI, reduces the risk factors of coronary heart disease, and improves the exercise ability and quality of life.
