OBJECTIVE: To explore the genetic etiology for a pregnant woman with a history of multiple adverse pregnancies and assess the phenotype-genotype correlation of 22q11.2 microduplication syndrome in her family. METHODS: Amniotic fluid sample was taken from a pregnant woman for whom non-invasive prenatal screening indicated chromosome 22 abnormalities in the fetus. Peripheral blood samples from the woman, her brother and parents were collected for high-throughput low-depth whole genome sequencing (CNV-seq). A pedigree traceability analysis of the results was conducted in conjunction with analysis of clinical manifestation. Relevant literature (from establishment to March 2025) was systematically searched. This study was approved by the Medical Ethics Committee of Mianyang Maternal and Child Health Care Hospital (Ethics No.: Lun Shen [2024]009). RESULTS: CNV-seq revealed that the fetus had harbored a 6.02 Mb duplication at 22q11.21q11.23. Karyotyping confirmed it as 46,X?dup(22)(q11.2). Pedigree verification demonstrated that the pregnant woman, her brother and mother had all carried the same duplication. Phenotypic analysis of the affected family members showed classic features of 22q11.2 microduplication syndrome, including hypernasal speech, low nasal bridge, congenital heart disease, and cognitive impairment. A total of 44 cases with full information (including three patients from this pedigree) were included in the analysis. The penetrance of 22q11.2 duplication was approximately 29.5% (13/44), and 52.3% (23/44) of the cases had inherited the variant from a phenotypically normal parent. CONCLUSION This study has identified the genetic basis for the woman's recurrent adverse pregnancies and phenotypic abnormalities in her family members. The scoliosis identified in her younger brother has not been previously reported, thereby may enrich the clinical phenotype of this syndrome. For fetuses identified with a 22q11.2 microduplication, detailed fetal imaging is recommended, and genetic counseling should be provided to the couples.

Objective:To explore the association of 21-gene recurrence score (RS) and clinicopathologic characteristics of hormone receptor (HR) positive T1-3N1M0 breast cancer and its value in prognosis evaluation.Methods:The clinicopathological data of 287 patients with T1-3N1M0 breast cancer were collected, the 21-gene assay was completed, and follow-up was conducted. According to the 21-gene RS, the patients were divided into the RS<26 and RS≥26 groups. The relationship between the 21-gene RS and clinicopathological characteristics, treatment, recurrence, and metastasis was analyzed. Univariate and multivariate statistical analyses were used to analyze the risk factors for disease free survival (DFS).Results:The median RS of the 287 patients was 16. There were 240 cases with RS <26 and 47 cases with RS≥26. Tumor size, grade, estrogen receptor (ER), progesterone receptor (PR), and Ki-67 index were significantly different between the two cohorts ( P<0.05 for all). After a median follow-up of 74 months, the recurrence rate in the RS<26 group (8.3%) was significantly lower than that in the RS≥26 group (23.4%), the locoregional recurrence (LRR) rates in the RS<26 and RS≥26 groups were 2.1% and 0%,and the distant metastasis (DM) rates were 6.3% and 23.4%, respectively. The 5-year relapse free survival (RFS) rates of patients with RS<26 and RS≥26 were 93.8% (95% CI: 90.7%-96.9%) and 87.2% (95% CI: 78.2%-97.3%), and the 5-year DFS rates were 92.1% (95% CI: 88.7%-95.6%) and 85.1% (95% CI: 75.5%-95.9%), respectively, with significant differences between the two cohorts ( P=0.007 and P=0.006, respectively). Univariate analysis showed age, tumor size, grade, PR status, Ki-67 index and RS were prognostic factors for DFS ( P<0.05 for all). Multivariate analysis showed that age and tumor size were independent significant predictors for DFS ( P<0.05). Conclusions:The 21-gene RS of T1-3N1M0 breast cancer is related to tumor size, grade, ER, PR, and Ki-67 index. RS is an important factor affecting DM and DFS.

The armadillo repeat containing 5 (ARMC5) gene is part of a family of protein-coding genes that are rich in armadillo repeat sequences, are ubiquitously present in eukaryotes, and mediate interactions between proteins, playing roles in various cellular processes. Current research has demonstrated that reduced expression or absence of the ARMC5 gene in various tumor tissues can lead to uncontrolled cell proliferation, thereby inducing a range of diseases. The ARMC5 gene was initially extensively studied in the context of bilateral macronodular adrenocortical disease (BMAD), with harmful pathogenic variants in ARMC5 identified in approximately 50% of BMAD patients. With advancing research, scientists have discovered that ARMC5 pathogenic variants may also have potential effects on other diseases and could be associated with increased susceptibility to certain cancers. This review aims to present the latest research progress on how the ARMC5 gene plays its role in tumors. It outlines the basic structure of ARMC5 and the regions where it functions, as well as the diseases currently proven to be associated with ARMC5. Moreover, some evidence suggests its relation to embryonic development and the regulation of immune system activity. In conclusion, the ARMC5 gene is a crucial focal point in genetic and medical research. Understanding its function and regulation is of great importance for the development of new therapeutic strategies related to diseases associated with its pathogenic variants.

Objective This study aims at establishing a teaching catalog and content for breast rare dis-eases and developing the syllabus for the breast rare disease using integrated multimodality of case-/problem-/resource-based learning(CBL+PBL+RBL).Methods By conducting bibliometrics co-occurrence analysis,we collected 6291 articles on breast rare disease published from January,1975 to June,2024.Additionally,we re-trieved the Textbook on Rare Diseases,the Catalog of Chinese Rare Disease,and Second Batch of Rare Dis-ease Catalog and then decided the teaching content.Results From 16,387 keywords,1000(6.1％)keywords were identified through co-occurrence analysis,including 50(0.3％)candidate diseases.These were classified into three categories:rare primary breast diseases,rare genetic mutation-related diseases associated with breast cancer,and rare systemic multi-system diseases involving the breast.From the candidate list,20(0.1％)rare primary breast diseases were further selected for their notable clinical teaching significance,and significant multi-systemic diseases affecting the breast,whether related to gene mutations or not.Teaching plans were draf-ted using a diversified parallel teaching approaches,taking into account the characteristics of different diseases and the focus of different teaching methods.Conclusions This study initiated the development of the teaching content for breast rare diseases and developed the teaching syllabus using the CBL+PBL+RBL integrated multi teaching model and targeting each rare breast disease for the critical point for teaching.

Objective:To analyze the clinical efficacy of arthroscopic transverse release of the iliotibial band through peritrochanteric space for the treatment of external snapping hip.Methods:A total of 30 patients (12 males and 18 females) with bilateral external snapping hip underwent arthroscopic transverse release of the iliotibial band through peritrochanteric space in Department of Sports Medicine, Senior Department of Orthopaedics, the Fourth Medical Center, Chinese PLA General Hospital were retrospectively analyzed from May 2021 and June 2022. The average age was 32.5±8.2 years (range, 17-51 years). At the same time, 30 patients who underwent arthroscopic external release of the iliotibial band through the external surface of the iliotibial band (external iliotibial band group) were selected as control group, including 13 males and 17 females, aged 29.5±6.8 years (range, 11-45 years). The visual analogue scale (VAS), modified Harris hip score (mHHS), and gluteal muscle contracture disability scale (GDS) were compared between the two groups at preoperative, 6 months postoperative, and final follow-up.Results:All patients successfully completed the operation and were followed up for 17.5±3.3 months (range, 12-25 months). The VAS scores of the two groups at the last follow-up were lower than those before operation ( P<0.05). The mHHS scores before operation, 6 months after operation and at the last follow-up in the peritrochanteric space group were 76.5 (67.0, 85.5), 98.5 (94.8, 100.0) and 100.0 (97.0, 100.0), respectively, and those in the external iliotibial band group were 80.5 (70.0, 86.0), 100.0 (96.0, 100.0) and 100.0 (99.5, 100.0). The differences in mHHS scores between the two groups were statistically significant for intragroup comparisons ( P<0.05); of these, 6 months postoperatively and at the last follow-up were greater than preoperatively, with statistically significant differences ( P<0.05); the differences at 6 months postoperatively and at the last follow-up were not statistically significant ( P>0.05). There was no significant difference in mHHS scores between groups at different time points ( P>0.05). The GDS before operation, at 6 months after operation and at the last follow-up were 47.0 (35.8, 64.5), 90.0 (81.0, 94.0) and 93.5 (89.8, 98.0) in the peritrochanteric space group, and 51.0 (38.0, 64.5), 50.0 (81.0, 94.0) and 93.5 (89.8, 98.0) in the external iliotibial band group, respectively. The differences in GDS between the two groups were statistically significant for intragroup comparisons ( P< 0.05); of these, 6 months postoperatively and at the last follow-up were greater than preoperatively, with statistically significant differences ( P<0.05); the differences at 6 months postoperatively and at the last follow-up were not statistically significant ( P>0.05). There was no significant difference in GDS between groups at different time points ( P>0.05). Conclusion:Arthroscopic transverse release of the iliotibial band through peritrochanteric space for the treatment of external snapping hip can effectively reduce hip pain and improve hip function, with satisfactory clinical results, and can be used as an alternative treatment to transverse release through the external surface of the iliotibial band.

Objective The objective of this study is to examine the expression level of the S100A7A protein in both gastric cancer tissues and cells,as well as to evaluate its impact on the malignant phenotype of gastric cancer(GC)cells.Methods Immunohistochemical assay was used to detect the expression characteristics of S100A7A in 21 gastric cancer tissues and their corresponding paracancerous tissues,as well as to investigate its correlation with gastric cancer clinicopathological factors.Gastric cancer cells were genetically modified to overex-press S100A7A through plasmid transfection.Subsequently,the impact of S100A7A on the proliferation,migra-tion,and invasion capacities of gastric cancer cells was assessed using cell proliferation assays(EdU assay and plate cloning assay)as well as cell migration and invasion assays(Transwell assay and scratch assay).Results The expression of S100A7A protein was higher in GC tissues than in paracancerous tissues;Overexpression of S100A7A may increase gastric cancer cell proliferation,migration,and invasion.Conclusion S100A7A is a possible oncogene in GC and is predicted to serve as a new diagnostic and therapeutic target for the disease.

Objective:To compare the efficacy and safety of azacitidine combined with venetoclax or CAG regimen in the treatment of newly treated elderly patients with acute myeloid leukemia (AML).Methods:A retrospective cohort study was conducted. The clinical data of 34 newly treated elderly patients with AML treated in the Fifth People's Hospital of Datong from May 2018 to August 2023 were retrospectively analyzed. According to the treatment regimen, all patients were divided into venetoclax group (azacitidine + venetoclax, 17 cases) and CAG group (azacitidine + CAG regimen, 17 cases). The clinicopathological characteristics, efficacy, adverse reactions and survival of the both groups were compared.Results:There were no statistically significant differences in the clinical data of both groups (all P > 0.05). The complete remission (CR) rate and the objective response rate (ORR) in venetoclax group were higher than those in CAG group [CR: 70.6%(12/17) vs. 47.1% (8/17); ORR: 82.4% (14/17) vs. 64.7% (11/17)],while the differences in CR and ORR were not statistically significant (χ 2 = 2.00, P = 0.163; χ 2 = 2.00, P = 0.244). The follow-up time[ M ( Q1, Q3)] was 25.4 months (7.2 months, 60.3 months). At the end of follow-up, 19 of 34 patients survived (13 cases in venetoclax group and 6 cases in CAG group); 15 died (4 cases in venetoclax group and 11 cases in CAG group). The median overall survival (OS) time was 14.22 months (95% CI: 8.2-60.3 months) and 10.56 months (95% CI: 7.2-50.2 months), respectively in venetoclax group and CAG group;the median progression-free survival (PFS) time was 9.97 months (95% CI: 5.4-40.5 months) and 6.82 months (95% CI: 5.0-36.2 months), respectively, and there were no statistically significant differences in OS and PFS between the two groups (all P > 0.05). Grade 3-4 hematological adverse reactions occurred in 16 and 14 patients in venetoclax group and CAG group, respectively. There were no significant differences in granulocyte deficiency time, platelet deficiency time, infection and bleeding incidence between the two groups (all P > 0.05). Conclusions:Azacitidine combined with venetoclax or CAG regimen have better clinical efficacy and safety for newly treated elderly patients with AML.
