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 explore the efficacy of online pulmonary rehabilitation (PR) management among community-dwelling patients with stable chronic obstructive pulmonary disease (COPD).Methods:This study was a single-center randomized controlled trail with an unblinded design. A total of 130 patients with stable COPD who visited Zhuanqiao Community Health Service Center in Shanghai Minhang District from October 2020 to March 2022 were randomly divided into study group and control group with 65 cases in each group. Both groups received conventional treatment, while patients in study group attended online rehabilitation management, including face-to-face rehabilitation instruction and multiple online guidance. Pulmonary ventilation function including forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1) and percentage of forced expiratory volume in the first second to forced expiratoty volume (FEV 1%pred), modified British Medical Research Council Dyspnea Scale (mMRC), chronic obstructive pulmonary disease assessment test (CAT), score of 6 minutes walking distance (6MWD) and DOSE (dyspnea, degree of airflow obstruction, smoking status, the number of exacerbation) index were measured at baseline and after 8 weeks of rehabilitation, and compared between two groups. Results:The baseline data of the two groups were comparable. After 8 weeks of management, FVC, FEV 1, FEV 1%pred, mMRC, CAT, 6MWD and DOSE index of both groups were improved compared with the baseline level(control group: t=-7.799, -7.581, -9.010, 3.565, 9.887, -16.677, 3.795; study group: t=-12.623, -13.914, -17.644, 7.404, 22.457, -26.826, 7.968; all P<0.05). The FEV 1%pred, CAT and 6MWD in the study group were better than those in the control group ( t=-2.939, 2.277,-2.130, all P<0.05); while there were no significant differences in FVC, FEV 1, mMRC and DOSE index between the two groups( t=-0.162, -1.280, 0.925, 1.939,all P>0.05). Conclusions:The online pulmonary rehabilitation management can better improve lung function, dyspnea symptoms and exercise tolerance of patients with stable COPD, which can be used for rehabilitation training and management of community-dwelling patients.

Objective To observe the clinical effects of cognitive behavioral therapy (CBT) combined with pulmonary rehabilitation on the treatment of patients with pneumoconiosis. Methods A total of 108 patients with pneumoconiosis were selected as the research subject using convenient sampling method. They were randomly divided into control group and CBT group, with 54 cases in each group. Patients in the control group were treated with conventional symptomatic treatment and pulmonary rehabilitation treatment for 12 weeks. While patients in the CBT group were treated with CBT treatment in addition to treatments of the control group. The therapeutic effect was analyzed. Results Before treatment, there was no statistical difference on score of Montreal Cognitive Assessment (MoCA), percentage of forced expiratory volume in one second to the predicted value (FEV₁%), forced expiratory volume in one second to force vital capacity ratio (FEV₁/FVC%), score of the Modified Medical Research Council Dyspnea Scale (mMRC), six minute walk distance (6MWD), Hospital Anxiety and Depression Scale (HADS) subscale scores of anxiety (HADS-A) and depression (HADS-D), and scores of Chronic Obstructive Pulmonary Disease Assessment Test (CAT), St. George's Respiratory Questionnaire (SGRQ), and serum levels of leptin, interleukin-6 (IL-6) and C-reactive protein (CRP) between the two groups (all P>0.05). After treatment, the score of MoCA, FEV₁%, FEV₁/FVC% and 6MWD increased (all P<0.05), while the scores of mMRC, HDS-A, HDS-D, CAT and SGRQ decreased (all P<0.05), and the levels of serum leptin, IL-6 and CRP decreased (all P<0.05) in the CBT group compared with the control group. Conclusion The combined treatment of CBT and pulmonary rehabilitation can better improve the cognitive ability, respiratory function, motor function, negative emotion and quality of life, and alleviate inflammatory response in patients with pneumoconiosis. It is of certain clinical application value.
