Among gynecologic malignancies, ovarian cancer is the most lethal, primarily due to its insidious early symptoms, lack of effective screening methods, and high risk of recurrence. It poses substantial challenges to clinical diagnosis and treatment. In recent years, the clinical application of poly ADP-ribose polymerase inhibitors has promoted a comprehensive management model that integrates targeted therapy with conventional treatments. This review, aiming to provide new perspectives and approaches for future research, summarizes the high-risk factors and first-line treatment strategies for ovarian cancer. Further studies should focus on optimizing personalized treatment strategies and exploring novel targeted therapies to improve patient survival outcomes.

OBJECTIVE: To observe the clinical effect of acupuncture and moxibustion combined with umbilical therapy on anxiety and depression in patients with neurogenic bladder (NB) after spinal cord injury (SCI). METHODS: Thirty cases of NB after SCI with anxiety and depression were selected and treated with acupuncture and moxibustion combined with umbilical therapy. Acupuncture was applied at Baihui (GV20), Yintang (GV24⁺), Sanyinjiao (SP6), Shenmen (HT7), Hegu (LI4), Taichong (LR3), once a day, continuous treatment for 4 weeks. Ginger moxibustion was applied at the bladder meridian of foot taiyang and governor vessel, once a day, continuous treatment for 4 weeks. In treatment of umbilical therapy, Chaihu (Radix Bupleuri), Yujin (Radix Curcumae), Rougui (Cortex Cinnamomi) were ground and mixed with the same amount of honey, put into the application, and the application was placed on the navel after filling the navel with fine salt, once a day for 4 weeks. Hamilton anxiety scale (HAMA) score, Hamilton depression scale (HAMD) score, urodynamic indexes (maximum urinary flow rate [Qmax], maximum detrusor pressure [Pdet-max], residual urine volume [RUV]), neurogenic bladder symptom score (NBSS), urinary symptom distress scale (USDS) score were compared before and after treatment, and the clinical efficacy was evaluated. RESULTS: After treatment, the scores of HAMA, HAMD, NBSS, USDS and RUVwere lower than those before treatment (P<0.05), and Qmax and Pdet-max were higher than those before treatment (P<0.05). The total effective rate was 93.3 (28/30). CONCLUSION Acupuncture and moxibustion combined with umbilical therapy can effectively relieve anxiety and depression symptoms, improve urination disorders in patients with NB after SCI.

Acetaminophen (APAP) is the primary cause of drug-induced acute liver failure. Ovarian tumor deubiquitinase 6A (OTUD6A), a recently discovered deubiquitinase of the OTU family, has been primarily studied in tumor contexts. However, its role in APAP-induced liver injury (AILI) remains unclear. Therefore, this study aimed to investigate the involvement of OTUD6A in the pathogenesis of AILI. Our findings demonstrated a substantial upregulation of OTUD6A in both the liver tissue and isolated hepatocytes of mice following APAP stimulation. OTUD6A knockout exacerbated APAP-induced inflammation, hepatocyte necrosis, and liver injury, whereas OTUD6A overexpression alleviated these pathologies. Mechanistically, OTUD6A directly interacted with the enhancer of zeste homolog 2 (EZH2) and selectively removed K48-linked polyubiquitin chains from EZH2, enhancing its stability. This resulted in increased protein levels of EZH2 and H3K27me3, as well as reduced endoplasmic reticulum (ER) stress and cell death in hepatocytes. Collectively, our research uncovers a novel role for OTUD6A in mitigating APAP-induced liver injury by promoting EZH2 stabilization.

【Objective】 To evaluate the application of monoclonal typing reagents and human anti-A/B antibodies for absorption-elution test in ABO grouping. 【Methods】 The specificity of monoclonal typing reagents and human anti-A/B antibodies with standard A, B, O and AB phenotypes at 4 ℃, room temperature, and 37 ℃ were compared. Affinity was evaluated by the titer, agglutination time and agglutination intensity of the reaction with A1/B cells. 29 samples with ABO discrepancy were tested to evaluate the ability of monoclonal typing reagents and human anti-A/B antibodies to detect weak antigens in absorption-elution test. 【Results】 The specificity and affinity of human anti-A/B antibodies are low, and monoclonal typing reagents have cross reactivity. Human anti-A/B antibodies can detect most weak antigens in absorption-elution test with no cross reactivity. 【Conclusion】 In ABO grouping, the human anti A/B antibody binding absorption-elution test can serve as a supplement method for identifying ABO weak antigens. Accurate results can be obtained with reasonable reagents and corresponding methodology in serological tests,thus ensuring the safety of blood transfusion.

【Objective】 To establish a rare blood group information supply platform in Shaanxi Province. 【Methods】 The rare blood group information supply platform consists of sample registration, result registration, donor files and inventory blood. The blood donation codes of voluntary blood donors were recorded for blood typing, and the antigen identification results of each blood group system were registered, all stored in the rare blood type information supply platform. When receiving an application for unusual or rare blood type missing multiple conventional antigens or a certain high-frequency antigen, the corresponding antigen negative blood donors and their blood status (in stock or not) were queried from the donor profile module of the platform, and the inventory of blood of rare blood type was monitored dynamically. 【Results】 The results showed that 5.060% (273/5 398) of rare Rh phenotype donors, 1.540‰ (51/33 010) of donors lacking multiple regular antigens, and 13 O-type donors lacking high-frequency antigens were recorded in the rare blood type information supply platform. Among them, 0.019‰ (3/158 484) of Jk(a-b-) phenotype, 0.436‰ (2/4 586) of Di(a+b-) phenotype, and 4.030‰ (8/1 983) of Fy (a-b+) phenotype were stored in the blood bank for rare blood type. 【Conclusion】 The establishment of rare blood group information supply platform can meet the urgent demand for blood of rare blood types in clinical practice and ensure the safety of blood transfusion.

【Objective】 To observe the distribution of non-ABO-HDN and its clinical relevance, so as to provide reference for clinical diagnosis and treatment. 【Methods】 A total of 287 cases of non-ABO-HDN recorded during January 2012 to August 2022 were enrolled and tested in our laboratory. The correlation between maternal history of blood transfusion, pregnancy, unexpected antibody titers, gender, ABO-HDN and transfusion therapy was analyzed by chi-square test. 【Results】 All 287 cases of non-ABO-HDN involved 13 kinds of unexpected antibodies of 6 blood group systems. Rh-HDN accounted for 96.17% (276/287), and anti-D-HDN accounted for 47.04% (135/287). The proportion of non-ABO-HDN patients without ABO-HDN requiring exchange/transfusion was significantly higher than that of non-ABO-HDN patients with ABO-HDN(P<0.05). The ratio of need for exchange/transfusion in the high titer group (>8) was significantly higher than that in the low titer group (≤8) (P<0.05). There was no significant difference in gender, mother′s history of blood transfusion, pregnancy and whether or not to exchange/transfusion (severity of illness). 【Conclusion】 Understanding the characteristics of non-ABO-HDN and the specific distribution of unexpected antibodies, the correlation between various factors and diseases and their clinical significance are conductive to timely taking necessary intervention measures and reducing the risk of complications.

【Objective】 To screen individuals with rare blood type of Kidd, Diego, Duffy blood group system among the voluntary blood donor in Shaanxi province and to establish on-line and physical database of rare blood type. 【Methods】 Jk(a-b-)phenotype donors were screened by 2 mol/L urea hemolysis test. Blood donors with Di(a+ b-) phenotype were screened by genotyping; Fy(a-) and D-- phenotype donors were screened by modified antiglobulin assay. 【Results】 Three cases of Jk(a-b-) phenotype were detected out of 158 484 voluntary blood donors. The distribution frequency of Jk(a-b-) phenotype was 0.019‰. Di(a+ b-) phenotype was detected in 2(0.436‰) cases out of 4 586 voluntary blood donor. Fy(a-) phenotype was detected in 8(4.034‰) cases out of 1 983 voluntary blood donors. D-- phenotype was not detected in 29 430 voluntary blood donors. 【Conclusion】 The on-line database of Kidd, Diego, Duffy blood group system had been established by large-size screening of blood donor samples, which can conclude the region′s population distribution and genetic characteristics of RBC blood group. And physical database could further be established using the technology of red blood cells cryopreservation when the conditionspermit, so as to provide the most compatible blood for the clinical effectively improve blood transfusion safety, and provide data support for blood early warning.

【Objective】 To observe the distribution of the unexpected antibodies in order to study the safety and strategies in 1 779 cases of clinical blood transfusion. 【Methods】 A total of 1 779 patients with unexpected antibodies were enrolled from transfusion candidates in various hospitals in Xi′an during a 10-year period(from 2012 to 2022.5). 【Results】 The unexpected antibodies were detected in 926(52.05%) of 1779 samples. The detected antibodies were mainly from 8 blood group systems and their distributions were as follows: Rh antibodies in 69.76%(646/926), Kidd in 2.59%(24/926), Lewis in 4.21%(39/926), MNS in 12.53%(116/926), P in 0.43%(4/926), Diego in 0.65%(6/926), Duffy in 0.54%(5/926), I in 0.97%(9/926), Rh+ MNS in 1.30%(12/926), Rh+ Lewis in 0.65%(6/926), Rh+ Kidd in 3.24%(30/926), Rh+ Diego in 1.51%(14/926), Rh+ Duffy in 0.86%(8/926), MNS+ Diego in 0.11%(1/926), Rh+ MNS+ Kidd in 0.22%(2/926), Rh+ Lewis+ Kidd in 0.22%(2/926), Rh+ Kidd+ P in 0.11%(1/926), Rh+ Kidd+ Diego in 0.11%(1/926). 【Conclusion】 According to the distribution of unexpected antibodies in Xi′an, antibodies from Rh system, were the most common ones.First, the production of unexpected antibodies can be effectively reduced by establishing Rh compatible blood transfusion. Secondly, antibody screen cells containing low-frequency antigens, such as Mur, Di^a and Wr^a, should be reasonably selected to prevent missing detection of anti-low frequency antigen antibodies in Xi′an. Furthermore, the genotyping technology of rare blood group should be promoted and a rare blood group red blood cell bank be established to optimize the blood inventory and ensure the safety of blood transfusion.

【Objective】 To identify one blood sample with ambiguous antibody screening result, explore the identification strategy of complex antibodies and provide blood transfusion plan. 【Methods】 Blood typing and antibody screening were performed by serological test. The genotyping of Diego blood group was carried out by gene detection. Absorption and elution test were designed to identify the complex antibodies. 【Results】 Serological test showed that the patient′s blood type was B, ccDEE, Jk(a-b+ ), Le(a-b+ ), Fy(a+ b-), Di(a+ b-). The results of genotyping showed that the Diego genotype of the patient was Di (a+ b-). Based on the above results, absorption and elution tests were designed and IgG anti-Di^b, IgG anti-Ce, and IgG anti-Jk^a antibodies were detected in serum of the patient. Combined with the use of immunoglobulin and targeted blood transfusion measures, successful treatment was provided for the patient. 【Conclusion】 For the identification of antibodies against high frequency antigen combined with multiple antibodies, a variety of experimental techniques and methods should be combined, and the experimental scheme should be designed flexibly.

【Objective】 To study the molecular mechanism of para-bombay blood group caused by two rare mutation combinations and investigate the pedigree. 【Methods】 ABO and H antigens were detected by serological test, and the ABO blood group was confirmed by gene detection; the FUT1 gene was amplified by PCR and sequenced. 【Results】 Serological results showed that the proband was a rare para-bombay blood Bhm, Le(a-b+ ), and the proband′s parents were both B Le (a-b + ).
