[Objective] To investigate the antigen and gene frequency distribution of the MNS blood group system in the Han population of voluntary blood donors in Suzhou, and to explore the polymorphism of rare MNS blood group genes, in order to improve the construction of the local rare blood group database. [Methods] A total of 8 034 whole blood samples were randomly collected from Han blood donors at our station from October 2023 to June 2024. The MNS blood group phenotypes were identified using serological methods. Gene frequencies were analyzed and compared with those of ethnic populations in other regions. Rare MNS phenotype samples were subjected to gene sequencing. [Results] The distribution of MNS blood group system phenotypes within the population was as follows: the MM, NN, and MN phenotypes accounted for 23.00%, 27.12%, and 49.88% respectively; the SS, ss, and Ss phenotypes accounted for 0.30%, 90.99%, and 8.70% respectively. The gene frequencies of M, N, S, and s were 0.4794, 0.5206, 0.0465, and 0.9534 respectively. Chi-squared tests confirmed adherence to Hardy-Weinberg equilibrium with P-values of 0.997 and 0.349, showing statistical significance compared to some other regional ethnic populations (P<0.05). Additionally, one rare serological phenotype, S-s-, with a frequency of 0.01%, was identified. [Conclusion] The MNS blood group system in the Han population of voluntary blood donors in Suzhou exhibits polymorphism and regional distribution characteristics. Gene frequencies differ from those observed in other regions of China. It is essential to enhance the establishment of a rare blood type database in Suzhou to provide data support for precise clinical transfusion.

Objective:To investigate the clinical characteristics and survival analysis of myelodysplastic syndromes(MDS)with RUNX1 gene mutation.Methods:Clinical data of 177 newly diagnosed MDS patients admitted to the Department of Hematology,the Second Affiliated Hospital of Air Force Military Medical University from October 1,2015 to October 31,2022 were retrospectively analyzed.Gene mutation detection was performed by second-generation sequencing technology,and clinical characteristics and prognosis of patients with RUNX1 gene mutation were analyzed.Results:A total of 30 cases(16.95％)of RUNX1 gene mutations were detected,including 15 missense mutations(50.0％),9 frameshift deletion mutations(30.0％),4 splice site mutations(13.3％),1 insertion mutation(3.3％),and 1 nonsense mutation(3.3％).Patients with RUNX1 mutations had a median age of 68.5 years at diagnosis(range:62.25-78.50 years old).There were no significantly differences between RUNX1 mutations and wild type patients in age distribution,gender,peripheral blood white blood cell count,hemoglobin level,bone marrow and peripheral blood blasts ratio,IPSS-R cytogenetics,IPSS-R stage,etc.(P＞0.05).However,there were statistically significant differences in platelet count and whether complicated karyotype.Compared with patients without RUNX1 gene mutation,patients with RUNX1 gene mutation had lower platelet count(P=0.018),and were less likely to have complicated karyotype at initial diagnosis(P=0.01).Cox proportional hazards model analysis showed that when other co variates remained unchanged,the higher the platelet count,the better the survival of patients(HR=0.995,95％CI:0.990-0.999,P=0.036);In the IPSS-M prognostic stratification,keeping other covariates unchanged,the risk of progression or death of myelodysplastic syndrome was significantly lower in the medium to high-risk and low-risk groups compared with the high-risk group(HR=0.149,95％CI:0.031-0.721,P=0.018;HR=0.026,95％CI:0.003-0.234,P=0.001).Survival analysis showed that MDS patients with RUNX1 gene mutation had worse overall survival time(P＜0.001).Patients with RUNX1 mutation had worse OS than non-mutation patients in the early WHO group.RUNX1 mutation and IPSS-M risk stratification mean OS and mean LFS were worse in low-risk patients than in non-mutated patients.Conclusion:RUNX1 gene mutation is an adverse prognostic factor in MDS patients,especially in the IPSS-M prognosis stratification group of low-risk,medium-low risk,medium-high risk and WHO classification of early patients.

To evaluate the application value of metal clip combined with suture and rubber coil as a simple traction device in endoscopic submucosal dissection (ESD) for intestinal mucosal lesions, a total of 56 patients with early colonic cancer and precancerous lesions who received ESD in Jiangyin People's Hospital from January 2021 to July 2022 were randomly divided into the control group ( n=28, conventional ESD) and the traction group ( n= 28, suture and rubber coil as a simple traction device). The total time of ESD, mucosal dissection time, number of submucosal injections, complete resection rate and complications were compared between the two groups. The operation time of the traction group was shorter than that of the control group (74.64±33.25 min VS 117.18±35.75 min, t=4.61, P<0.001). The desection time of mucosa in the traction group was shorter than that in the control group (51.61±24.87 min VS 99.11±32.73 min, t=6.11, P<0.001). The number of submucosal injection in the traction group was less than that of the control group with significant difference (1.68±1.16 VS 4.96±1.41, t=9.57, P<0.001). There was no significant differences in operation area, complete resection rate or complication between the two groups ( P>0.05). The traction assistance technology of metal clip combined with suture and rubber coil can reduce the technical difficulty of colonic ESD and shorten the operation time.

The China Association of Chinese Medicine （CACM） carried out a series of youth salon seminars for clinical dominant diseases in TCM， discussing and sorting out the advantages of the dominant diseases in clinical diagnosis and treatment of TCM and integrated traditional Chinese and western medicine in specific diseases or fields. Authoritative experts in the industry were invited to give comment and guidance to form a report. Centering on clinical research of dominant diseases， thematic research was carried out in the aspects of practice， human experience-based evidence， and transformation path. Through the systematic study of the dominant diseases， the advantages of TCM in different stages of disease treatment were excavated to constantly improve the prevention and treatment ability of TCM and carry forward the advancement of TCM theory and practice. At the same time， the communication and understanding between traditional Chinese and western medicine were improved， laying the foundation for the further formation of industry guidelines or consensus and comprehensive promotion. These seminars are expected to provide references for the development of policy planning， clinical diagnosis and treatment， health economy， and social services in TCM and lay the foundation for the formation of a new modern diagnosis and treatment system with Chinese characteristics.

Objective:To investigate the surgical treatment strategies of brachial plexus schwannomas protruding from the foraminal area to the thoracic outlet through anterior cervical approach, and to evaluate the curative effect.Methods:The clinical data of 8 patients treated in Beijing Friendship Hospital Affiliated to Capital Medical University from July 2016 to December 2020 who underwent supraclavicular cervical "barb" incision for protruding into the thoracic outlet through anterior cervical approach were retrospectively collected, including 5 males and 3 females, aged (50.75±11.14) years old, ranging from 31-66 years old. And the key points of the operation, postoperative complications and postoperative follow-up were analyzed. Measurement data with normal distribution were represented as mean±standard deviation( ± s), count data were described as numbers. Results:The tumors in all 8 cases were totally resected.The amount of bleeding during operation was (35.00±14.14) mL. No surgical complications such injury of pleura, aspneumothorax and hemothorax, except 2 cases which developed local sensory disturbance that improved that after neurotrophic treatment and hormonotherapy. All 8 patients were followed up by outpatient or telephone for 1-5 years, and cervical MRI review showed no tumor recurrence in situ.Conclusions:The anterior cervical approach with "barb type" incision above the neck clavicle is effective in excision of schwannomas protruding into the thoracic outlet, with less intraoperative injury, less blood loss, fast postoperative recovery.

Objective: To investigate the application effect of augmented reality and mixed reality navigation technology in three-dimensional(3D) laparoscopic narrow right hepatectomy(LRH). Methods: A retrospective analysis was performed on the clinical data of 5 patients with hepatic malignancy admitted to the First Department of Hepatobiliary Surgery,Zhujiang Hospital,Southern Medical University from September 2020 to June 2021,all of whom were males,aged from 42 to 74 years.Preoperative evaluation was performed using the self-developed 3D abdominal medical image visualization system; if all the 5 patients were to receive right hemihepatectomy,the remnant liver volume would be insufficient,so LRH were planned.During the operation,the independently developed 3D laparoscopic augmented reality and mixed reality surgical navigation system was used to perform real-time multi-modal image fusion and interaction between the preoperative 3D model and 3D laparoscopic scene.Meanwhile,intraoperative ultrasound assisted indocyanine green fluorescence was used to determine the surgical path.In this way,the LRH under the guidance of augmented reality and mixed reality navigation was completed.The predicted liver resection volume was evaluated before surgery,actual resected liver volume,surgical indicators and postoperative complications were analyzed. Results: All the 5 patients completed LRH under the guidance of augmented reality and mixed reality navigation technology,with no conversion to laparotomy.The median operative time was 300 minutes(range:270 to 360 minutes),no intraoperative blood transfusion was performed,and the median postoperative hospital stay was 8 days(range:7 to 9 days).There were no perioperative deaths,or postoperative complications such as liver failure,bleeding,or biliary fistula. Conclusion: For patients who need to undergo LRH,the use of augmented and mixed reality navigation technology can safely and effectively guide the implementation of surgery,retain more functional liver volume,improve surgical safety,and reduce postoperative complications.

OBJECTIVE: To investigate the characteristics of gene mutation, clinical characteristics and significance in acute leukemia (AL) patients. METHODS: The clinical data of 102 AL patients in Hebei General Hospital from September 2016 to September 2020 were collected and analyzed retrospectively, including the characteristics of gene mutation, age, peripheral blood cells, bone marrow blasts, leukemia subtypes and myeloperoxidase (MPO). RESULTS: The total gene mutation rate was 87.25% (89/102) in all 102 patients. A total of 275 gene mutations were detected, with an average of 2.70 gene mutations per patient. The most frequent mutations of 102 patients were as follows: CEBPA (6.91%), NPM1 and ASXL1(6.18%), TET2 (5.82%), DNMT3A (5.45%), IDH2 and FLT3-ITD (5.09%). Gene mutations often occurred simultaneously. CEBPA mutation occurred in 10 cases of M2 subtype, while TET2 mutation occurred in 9 cases of M2 subtype. Among the most common gene mutations in MPO low expression group, mutation rates of NPM1, DNMT3A, IDH2, SF related gene mutation and RUNX1 were significantly different than those in MPO high expression group (all P<0.05). Univariate analysis showed that age, NPM1, DNMT3A and FLT3-ITD had significant effects on leukocyte level. Logistic regression analysis showed that patients with positive NPM1 mutations may had higher leukocyte levels (p=0.038), and those with positive DNMT3A mutations may had higher platelet levels (p=0.042). CONCLUSION The incidence of gene mutation in patients with AL is high, and it often occurs simultaneously. CEBPA and TET2 gene mutations are more common in M2 subtype. In patients with MPO low expression, the most common gene mutations are NPM1, DNMT3A and IDH2. AL patients with NPM1 gene mutation had higher white blood cell levels, while with DNMT3A gene mutation had higher platelet levels.
