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.

Taking the Department of Pathology of Duke University as an example, this paper compares and analyzes the training mode of pathology residents in China and the United States. It is found that the organization and management system and supervision and assessment system of residency training in China have been improved, but it is still necessary to strengthen the in-depth implementation of humanistic education and training subjects for residents. Pathologist training should be based on "elite education" as the guiding ideology, to cultivate high-quality, high-level outstanding clinical pathology personnel as the specific goal, to build a solid foundation of clinical medicine.

Objective: To observe the clinical efficacy of pediatric Tuina (Chinese therapeutic massage) plus oral administration of Chinese medication for pediatric anorexia due to spleen failing in transportation. Methods: A total of 94 children with anorexia due to spleen failing in transportation were randomized into an observation group and a control group by the random number table method at a ratio of 1:1, with 47 cases in each group. The control group was treated with modified Bu Huan Jin Zheng Qi San, and the observation group was treated with additional Tuina manipulation of Yun Shui Ru Tu based on the treatment in the control group. After 4 weeks of treatment, the clinical efficacy of the two groups was observed, and the traditional Chinese medicine (TCM) symptom score, serum leptin, neuropeptide Y, and serum zinc and calcium levels were compared. Results: After 4 weeks of treatment, the total effective rate of the observation group was 87.2%, and that of the control group was 74.5%. The difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased significantly (P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). After treatment, the serum leptin level in both groups decreased, and the level in the observation group was lower than that in the control group (P<0.05). The serum neuropeptide Y, zinc, and calcium levels in both groups increased after treatment, and the levels in the observation group were higher than those in the control group (P<0.05). Conclusion: Tuina manipulation of Yun Shui Ru Tu plus oral administration of Chinese medication is significantly effective in treating pediatric anorexia due to spleen failing in transportation, which can improve the appetite of children and improve the symptoms of anorexia, and the curative effect is better than that of oral administration of Chinese medication alone.

Objective:To investigate the awareness rate of " 1+ 1+ 1" contracted residents in the outer suburbs of Shanghai on the extended prescription policy of the family doctor contract service, and to analyze the influencing factors.Methods:From March to May, 2021, the cluster random sampling method was used to select one community health service center in Fengxian district, Shanghai, and a smart voice telephone assistant survey was conducted among the contracted residents aged 18 and above in the area, to understand their awareness of the extended prescription policy. χ2 Test was used for single factor analysis on the influence of different factors on the policy awareness of the contracted residents, while a multivariate analysis was performed by binary logistic regression, presenting P<0.05 as statistically significant. Results:A total of 13 495 " 1+ 1+ 1" contracted residents were surveyed via phone calls. Their awareness rate of extended prescription policy was 67.5% (9 115/13 495), while those with higher awareness rates were patients with ≥2 chronic diseases (92.3%), patients with 1 chronic disease (88.5%) and those aged 81 and above (88.4%). Logistic regression analysis showed that age, marital status, the number of chronic diseases and signing duration were all independent factors influencing the awareness of extended prescription policy (all P<0.05), while whether the residents were key population groups presented no significant influence on the awareness of extended prescription policy ( P=0.431). Conclusions:The awareness rate of " 1+ 1+ 1" contracted residents in the outer suburbs of Shanghai to the extended prescription policy needs to be further improved and publicity should also be strengthened to extend the policy benefit coverage.

Objective:To evaluate the oncologic outcomes of different laparoscopic radical hysterectomy.Methods:From January 2011 to December 2014, the laparoscopic operation cases of cervical cancer at stage Ⅰb1, Ⅰb2, Ⅱa1 and Ⅱa2, including the histologic subtypes of squamous-cell carcinoma, adenocarcinoma and adenosquamous carcinoma, were collected in five clinical centers. The data were divided into two groups according to the surgical procedures, that is, modified laparoscopic-vaginal radical hysterectomy (mLVRH) and total laparoscopic radical hysterectomy (TLRH). The overall survival rate (OS), disease-free survival rate (DFS) at 5 years were retrospectively analyzed in this study.Results:There were 674 cases in total, including 377 cases of mLVRH, 297 cases of TLRH. (1) The OS at 5 years: the mLVRH was 96.1% and the TLRH was 92.0%, and the mLVRH was higher than that of TLRH ( P=0.010). Stratify analysis, including stage of disease (Ⅰb1 and Ⅱa1), histologic subtypes (squamous-cell carcinoma, adenocarcinoma), lymph node metastasis, revealed that, ① Stage of disease: in stage Ⅰb1, the OS at five years of mLVRH was higher than that in TLRH group (98.6% vs 93.6%, P=0.012). In stage Ⅱa1, there was significant difference between the two groups, the OS at five years of mLVRH and TLRH were 93.6% and 77.6% ( P=0.007). ② Histologic subtypes: for the OS at five years of squamous-cell carcinoma, mLVRH and TLRH were 96.1% and 92.3%, and there was significant difference ( P=0.046); for adenocarcinoma, the OS at five years were 91.0% and 88.6%, and there was no difference between two groups ( P=0.230). ③ Lymph node metastasis: the mLVRH and TLRH with lymph node metastasis, the OS at five years were 98.6% and 96.4%; the mLVRH and TLRH without lymph node metastasis, the OS at five years were 89.3% and 80.8%. There were no significant differences between the two groups,respectively ( P=0.156, P=0.093). (2) The DFS at 5 years: there was no significant difference between mLVRH and TLRH (94.1% vs 90.9%, P=0.220). Stratify analysis for stage of disease, the mLVRH group was higher than that in the TLRH group in stage Ⅰb1 (97.0% vs 92.8%, P=0.039). However, for stage Ⅱa1, there was no significant difference between mLVRH and TLRH group (88.2% vs 75.8%, P=0.074). Conclusions:The results of this retrospective study indicated that different laparoscopy surgical procedures had diverse oncologic outcomes. The OS at 5 years of the mLVRH is superior to the TLRH. The DFS at 5 years in Ⅰb1 stage, the mLVRH is higher than the TLRH. Therefore, the modified laparoscopy is still an alternative surgery for early cervical cancer patients when following the principle of no-tumor-exposure.
