Objective To understand the driver gene mutation status in patients with non-small cell lung cancer (NSCLC) in Xi'an City, and to analyze the association with environmental exposure factors. Methods A total of 305 NSCLC patients admitted to the First Affiliated Hospital of the Air Force Medical University from January 2019 to December 2023 were included. The driver gene mutation status was observed, and the relationship with environmental exposure factors was analyzed. Results The driver gene mutation rate of 305 patients was 46.89%, with EGFR gene mutation accounting for the highest proportion, and 4 cases of gene co-mutations were detected. There was a difference in gender among patients with different single drive gene mutations (P<0.05), and the proportion of EGFR in women was significantly higher (P<0.05). Univariate analysis showed that there were statistical differences in family history, smoking history, long-term cooking history, and fried smoked food intake between patients with driver gene mutation and patients without driver gene mutation (P<0.05). Logistic regression analysis suggested that long-term cooking history (OR=2.392), and fried smoked food intake (OR=2.849) were the environmental exposure factors affecting EGFR gene mutation (P<0.05), and smoking history (OR=1.377) was an environmental exposure factor of KRAS gene mutation (P<0.05). Conclusion EGFR gene mutation accounts for the highest proportion of NSCLC patients in Xi'an City, and is mainly female. Long-term cooking history, and fried smoked food intake are related to EGFR gene mutation. There is a certain association between smoking history and KRAS gene mutation.

Objective To understand the current status of stigma among lung cancer patients in Yunnan and analyze its influencing factors.Methods A convenience sampling method was employed to select 248 lung cancer patients from a tertiary cancer hospital in Yunnan from July 2022 to July 2023.A demographic questionnaire and the Chinese version of the Lung Cancer Patient Stigma Scale were used to investigate their demographic characteristics and stigma levels.Results The total score of stigma in lung cancer patients was(96.92±14.87).Multiple linear regression analysis showed that education level,long-term residence,ethnicity and family relationship were the influencing factors of stigma score in lung cancer patients(P<0.05).Conclusion The stigma level among lung cancer patients is relatively high.Patients with higher education levels,those living in rural areas for a long time,ethnic minorities,and those with better family relationships exhibited higher stigma levels.Enhancing the accessibility of medical resources,establishing a comprehensive social support system,and paying attention to and respecting the cultural differences and beliefs of lung cancer patients can provide them with greater understanding,support,and encouragement,thereby reducing the stigma levels.

ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndromes in intrahepatic cholestasis of pregnancy （ICP） and its association with perinatal outcomes， and to provide a basis for precise treatment based on TCM syndrome differentiation. MethodsA cross-sectional study was conducted among 275 patients with ICP who were admitted to The Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from April 2023 to April 2025. A hierarchical cluster analysis was used to summarize TCM syndromes. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups， and the chi-square test was used for comparison of categorical data between groups. A multivariate Logistic regression analysis was used to identify the clinical features significantly associated with TCM syndrome. ResultsThe cluster analysis identified three core TCM syndromes among the 275 patients with ICP， i.e.， liver-gallbladder damp-heat syndrome （45.8%）， syndrome of blood deficiency generating wind （30.9%）， and liver depression and spleen deficiency syndrome （23.3%）. There was a significant difference in the distribution of TCM syndromes between different groups stratified by maternal age at delivery， parity， history of ICP recurrence， gestational weeks at disease onset， total bile acid （TBA）， alanine aminotransferase （ALT）， and comorbidity with gestational diabetes mellitus （GDM） （all P<0.05）. The multivariate Logistic regression analysis showed that<34 gestational weeks at disease onset was significantly associated with all three syndromes （damp-heat： odds ratio ［OR］=3.769， P<0.001； blood deficiency： OR=4.031， P<0.001； liver stagnation： OR=3.552， P<0.001）. Liver-gallbladder damp-heat syndrome was associated with maternal age ≥35 years at disease onset （OR=2.048， P=0.014）， parity ≥2 times （OR=1.921， P=0.034）， history of ICP recurrence （OR=2.404， P=0.030）， ALT ≥200 U/L （OR=2.051， P=0.018）， comorbidity with GDM （OR=1.944， P=0.029）， and TBA ≥40 μmol/L （OR=2.542， P=0.024）. The syndrome of blood deficiency generating wind syndrome was associated with maternal age ≥35 years （OR=2.939， P=0.003）， parity ≥2 time （OR=3.222， P=0.003）， history of ICP recurrence （OR=3.809， P=0.010）， ALT ≥200 U/L （OR=2.889， P=0.006）， comorbidity with GDM （OR=3.711， P=0.001）， and comorbidity with hypertensive disorders of pregnancy （OR=4.472， P=0.011）. Liver depression and spleen deficiency syndrome was associated with TBA ≥40 μmol/L （OR=2.995， P=0.044）. The analysis of perinatal outcomes showed that there were significant differences in mode of delivery， gestational weeks at the time of delivery， postpartum blood loss， and neonatal birth weight between the three groups with different TCM syndromes （all P<0.05）. ConclusionLiver-gallbladder damp-heat syndrome， syndrome of blood deficiency generating wind， and liver depression and spleen deficiency syndrome are the main TCM syndrome types in ICP， and the distribution of TCM syndromes is closely associated with clinical factors and perinatal outcomes， which provides a basis for precise TCM syndrome differentiation and individualized treatment.

Objective To determine the role of AAMP in osteosarcoma cells and explore the mechanism of invasion and metastasis of osteosarcoma cells regulated by AAMP through the YAP signaling pathway.Methods Public sequencing data analysis was used to explore the correlation between AAMP and osteosarcoma.q-PCR,Western blot,and immunohistochemistry were used to detect the expression levels of osteosarcoma cell-related molecules.CCK-8 was used to detect cell proliferation ability.Transwell and wound healing assays were used to detect the invasive and metastatic abilities of osteosarcoma cells.Immunofluorescence was used to detect the cell localization and expression levels of related molecules.Results High expression of AAMP was negatively correlated with the prognosis of patients with osteosarcoma(P<0.05),and the expression of AAMP in patients with metastatic osteosarcoma increased(P<0.05).Compared with the control group,the AAMP interference group showed significantly decreased migratory,invasive,and EMT activities(P<0.05).The expression of p-CFL1 reduced after the knockdown of AAMP,and the cell plate pseudopods decreased significantly(P<0.05).A positive correlation was found between the expression levels of AAMP and YAP in osteosarcoma cells(P<0.05).Interfering with YAP expression can affect the migration and invasion of osteosarcoma cells.Conclusion AAMP promotes osteosarcoma cell metastasis by regulating the YAP signaling pathway,suggesting that AAMP may be a key molecule in promoting invasion and metastasis of osteosarcoma.

Objective: To analyze the epidemiological and etiological characteristics of hand-foot-mouth disease (HFMD) in Tongren City during 2018 to 2022, so as to provide the reference for HFMD effective prevention and control. Methods: Monitoring data on HFMD in Tongren City from 2018 to 2022 was collected from National Infectious Disease Reporting Information Management System. Descriptive epidemiological method was conducted on the data analysis. Results: A total of 14 376 cases of HFMD were reported in Tongren City during 2018 to 2022, the average annual incidence rate of HFMD was 89.43/100 000. Totally 47 severe cases were reported, accounting for 0.33% of the total cases. The incidence rates of HFMD were generally declining trend during 2018 to 2022 (124.68/100 000, 95.37/100 000, 78.50/100 000, 61.63/100 000, 87.80/100 000) ( χ 2 trend =393.05, P <0.01), mainly occurred during April to July (48.13%), among children under 5 years old (95.72%). During 2018 to 2022, a total of 967 laboratory diagnosed cases reported in different years, regions, age groups showed significant differences in pathogen composition ratio ( χ 2=169.62, 456.65 , 167.96, P <0.05). From 2018 to 2022, the dominant pathogen of HFMD was constantly changing. Other enteroviruses were the dominant epidemic strains in 2018 and 2022 (33.04%, 37.62%), CoxA 6 was the dominant epidemic strain in 2019 to 2020 ( 68.75 %, 50.78%), and CoxA16 was the dominant epidemic strain in 2021(43.30%).In 2018, one case was infected with CoxA16 and EV71.The difference of pathogen composition ratio varied in different years ( χ 2=169.62, P <0.01). Conclusions The prevalence of HFMD in Tongren City has showed a declining trend during 2018 to 2022, and the dominant strain of HFMD has changed in recent years. The pathogen monitoring of HFMD should be strengthened to timely grasp the distribution and changes of pathogens, so as to provide a basis for the precise prevention and control of HFMD.

Metastasis is crucial for the mortality of non-small cell lung carcinoma (NSCLC) patients. The epithelial-mesenchymal transition (EMT) plays a critical role in regulating tumor metastasis. Glioma-associated oncogene 1 (Gli1) is aberrantly active in a series of tumor tissues. However, the molecular regulatory relationships between Gli1 and NSCLC metastasis have not yet been identified. Herein, we reported Gli1 promoted NSCLC metastasis. High Gli1 expression was associated with poor survival of NSCLC patients. Ectopic expression of Gli1 in low metastatic A549 and NCI-H460 cells enhanced their migration, invasion abilities and facilitated EMT process, whereas knock-down of Gli1 in high metastatic NCI-H1299 and NCI-H1703 cells showed an opposite effect. Notably, Gli1 overexpression accelerated the lung and liver metastasis of NSCLC in the intravenously injected metastasis model. Further research showed that Gli1 positively regulated Snail expression by binding to its promoter and enhancing its protein stability, thereby facilitating the migration, invasion and EMT of NSCLC. In addition, administration of GANT-61, a Gli1 inhibitor, obviously suppressed the metastasis of NSCLC. Collectively, our study reveals that Gli1 is a critical regulator for NSCLC metastasis and suggests that targeting Gli1 is a prospective therapy strategy for metastatic NSCLC.

Objective:To summarize the management of unicornuate uterus with ectopic ovary during in vitro fertilization and embryo transfer (IVF-ET). Methods:The clinical data of 2 rare cases of uniangular uterus with ectopic ovary undergoing IVF-ET were retrospectively analyzed and the related literatures were reviewed.Results:Two patients were diagnosed as unicornuate uterus with unilateral ovary missing by vaginal ultrasound, subsequent abdominal ultrasound and magnetic resonance imaging (MRI) results indicated follicular structure in the peritoneal area, suggesting ectopic ovary. Case 1 showed flank pain as well as discrepancy between serum estradiol level and follicle numbers during ovarian hyperstimulation. The patient received trans-abdominal combined with trans-vaginal oocyte retrieval and successfully delivered a healthy baby at 36 weeks by transferring frozen blastocyst embryo. Case 2 was diagnosed as unicornuate uterus with lateral ectopic ovary by abdominal ultrasound before IVF treatment. We performed synchronized monitoring of bilateral ovarian follicular development and oocytes retrieval by transabdominal and transvaginal ultrasound, and then the two blastocysts were cryopreserved. However, the patient experienced spontaneous abortion following single frozen-thawed blastocyst transfer.Conclusion:Ectopic ovaries present no obvious clinical manifestation and is easy to be ignored in diagnosis. For patients with unicornuate uterus treated by assisted reproductive technology, if vaginal ultrasound fails to detect ovary, we should further perform abdominal ultrasound or MRI to screen for ectopic ovary. If diagnosed with ectopic ovary, the patients should simultaneously be monitored the follicullar development of bilateral ovaries during the process of ovarian hyperstimulation and adopt both transabdominal and transvaginal ultrasound-guided follicular aspiration to maximize the numbers of oocyte and pregnancy chance.

Objective:To explore the analysis of staging alteration and prognosis of 8th edition of the American Joint Committee on Cancer (AJCC) staging update for breast cancer with different molecular subtypes.Methods:The clinical data of 965 breast cancer patients treated in Xijing Hospital from January 2011 to December 2017 were retrospectively collected, and 103 patients met the inclusion criteria. The staging results between all the patients and patients with 4 different molecular subtypes were compared according to the 7th and 8th edition of the AJCC. Fisher's exact test was used for staging differences, Kaplan-Meier was used for survival analysis, log-rank test was used to compare survival rates of different groups, the prognostic judgement efficacy and staging alteration for all patients and cases with different molecular subtypes in the 8th edition was also compared.Results:Compared with the 7th edition, a total of 52 cases (50.5%) had staging declined and 8 cases (7.8%) had staging risen in the 8th edition, and there was a statistically significant difference in composition change ( P < 0.05). There was no rise in staging for Luminal subtype patients, but the decline in 34 cases, with the decline rate of 87.2% (34/39); no rise in staging for patients of HER2 + subtype, but the decline in4 cases, with the decline rate of 19.0% (4/21). No rise in staging for triple positive subtype patients, but the decline in 14 cases, with the decline rate of 82.4% (14/17). Oppositely, for the patients with previous subtypes, no decline in staging of patients with triple negative subtypes, but the rise in 8 cases with the rise rate of 30.8% (8/26). The difference in all the above staging changes was statistically significant ( P = 0.001). According to the 7th edition of the AJCC, the disease-free survival (DFS) time of all the cases and Luminal subtype patients had no statistical differences among different staging groups ( P > 0.05), but according to the 8th edition of the AJCC, the differences were statistically significant ( P < 0.05). DFS time was shorten with the increase of staging, indicating that the 8th edition of staging could more accurately assess the prognosis of patients. Conclusions:Compared with the 7th edition of the AJCC, for the staging changes determined by the 8th edition of the AJCC, the proportion of staging declined in all the cases is significantly higher than that of staging risen, and patients with different molecular subtypes has different staging changes, among which the patients with the triple negative subtypes have staging risen and the rest have staging declined. The DFS analysis for all the patients and patients with Luminal subtypes indicates that the 8th edition of the AJCC staging is a more accurate predictor of prognosis compared with the 7th edition of the AJCC.
