Objective To understand the disease spectrum of a natural village in an area with high incidence of esophageal cancer to provide a reference for precise prevention and control. Methods From 2008 to 2024, 711 asymptomatic people over the age of 35 years in a natural village with high incidence of esophageal cancer in China were surveyed, and 171 of them were subjected to gastroscopy, biopsy, and pathological examination. All participants were followed up for a long time, and their disease history was recorded. Results A total of 16 years of follow-up were performed, and 703 people were effectively followed up. In 2008, 171 people underwent gastroscopy, and 160 people had biopsy and pathological results in endoscopic screening. By 2024, 76 people had been diagnosed with malignant tumors of 12 different types, and among these people, 45 had esophageal cancer. Conclusion Esophageal cancer remains a significant cause of morbidity and mortality from malignant tumors in this region. Biopsy and pathological examination should be strengthened during gastroscopy, and follow-ups and regular check-ups should be given high importance to reduce the incidence and mortality rates of esophageal cancer.

Purpose To demonstrate the advantages of non-contrast-enhanced whole-heart coronary magnetic resonance angiography(NCE-CMRA)in evaluating coronary arteries by comparing ultrasonography(US),and to explore the clinical value of NCE-CMRA in the diagnosis of coronary artery lesions of Kawasaki disease(KD)in children.Materials and Methods NCE-CMRA and US imaging data of 41 children with KD from June 2017 to June 2021 who were diagnosed clinically in Lanzhou University Second Hospital were analyzed retrospectively.The display ability of US and NCE-CMRA in coronary arteries were compared.At the same time,the imaging characteristics of NCE-CMRA were analyzed,and the imaging characteristics such as the range and degree of coronary artery lesions displayed by NCE-CMRA were summarized.Results The overall segment display rate of NCE-CMRA in 41 children with KD was 75.6%;the overall segment display rate of US was 46.3%,with statistical difference between the two techniques(χ2=59.04,P<0.001).Regarding the display of the middle and distal segments of coronary arteries,NCE-CMRA had a clear imaging advantage over US(χ2=57.98 and 161.47,P<0.001).In all cases,25 patients(200 segments)had coronary artery lesions,and 94 segments of coronary artery showed different degrees of dilatation,including 8 segments(8.6%)of giant coronary artery aneurysm,35 segments(37.2%)of medium coronary artery aneurysm,and 51 segments(54.2%)of small coronary artery aneurysm or coronary artery dilation.Conclusion NCE-CMRA technology can objectively and accurately display coronary artery in children,and it can specifically evaluate the degree of damage caused by KD.It has important clinical significance in the diagnosis and evaluation of coronary artery lesions in children with KD.

Purpose: The unique chromosomal rearrangements of endometrial stromal sarcoma (ESS) make it possible to distinguish high-grade ESS (HGESS) and low-grade ESS (LGESS) from the molecular perspective. Analysis of ESS at the genomic and transcriptomic levels can help us achieve accurate diagnosis of ESS and provide potential therapy options for ESS patients. Materials and Methods: A total of 36 ESS patients who conducted DNA- and/or RNA-based next-generation sequencing were retrospectively enrolled in this study. The molecular characteristics of ESS at genomic and transcriptomic levels, including mutational spectrum, fusion profiles, gene expression and pathway enrichment analysis and features about immune microenvironment were comprehensively explored. Results: TP53 and DNMT3A mutations were the most frequent mutations. The classical fusions frequently found in HGESS (ZC3H7B-BCOR and NUTM2B-YWHAE) and LGESS (JAZF1-SUZ12) were detected in our cohort. CCND1 was significantly up-regulated in HGESS, while the expression of GPER1 and PGR encoding estrogen receptor (ER) and progesterone receptor (PR) did not differ significantly between HGESS and LGESS. Actionable mutations enriched in homologous recombination repair, cell cycle, and phosphoinositide 3-kinase/AKT/mammalian target of rapamycin pathways were detected in 60% of HGESS patients. Genes with up-regulated expression in HGESS were significantly enriched in five immune-related pathways. Most HGESS patients (85.7%) had positive predictors of immunotherapy efficacy. Moreover, immune microenvironment analysis showed that HGESS had relatively high immune infiltration. The degree of immune infiltration in HGESS patients with ZC3H7B-BCOR fusion was relatively higher than that of those with NUTM2B-YWHAE fusion. Conclusion This study investigated the molecular characteristics of ESS patients at the genomic and transcriptomic levels and revealed the potentially high sensitivity of targeted therapy and immunotherapy in a subset of HGESS with specific molecular features, providing a basis for guiding decision-making of treatment and the design of future clinical trials on precision therapy.

Objective    To evaluate the efficacy of hybrid ablation through compared with thoracoscopic epicardial ablation. Methods    In this study, 108 patients with all long-standing persistent atrial fibrillation (LSPAF) received thoracoscopic epicardial ablation (TEA) after enrollment. There were 82 males and 26 females at age of 56.5±9.4 years. After blanking-period, patients off antiarrhythmic therapy with sinus rhythm were divided into a hybrid ablation (HA) group (50 patients) and a TEA group (58 patients). Only patients in the HA group received catheter ablation after randomization subsequently. In at least two-year observation period, cardiovascular risk factors were observed in all groups’ patients. Results    The mean follow-up duration was 17.3-41.8 (26.9±6.1) months and there was no significant difference between two groups [8.2-40.6 (27.5±5.7) months in the HA group and 17.3-41.8 (26.4±6.7) months in the TEA group]. The off antiarrhythmic agents (AADs) sinus rhythm rate was significantly higher in the HA group than that in the TEA group at the time of postoperative 6, 12, 24 and 36 months ［96.0%, 90.0%, 83.7%, 83.7% versus 79.3%, 75.9%, 67.3%, 63.1%, HR=0.415 (95%CI 0.206-0.923)]. Conclusion    We can conclude that the efficacy of two-staged hybrid ablation for LSPAF is superior to thoracoscopic epicardial ablation alone. Patients can obtain benefit from a supplemental radiofrequency catheter ablation after blanking-period of surgical ablation, instead of those without a supplemental ablation.

Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors. Results: The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05). Conclusion The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

Objective:To investigate the clinical manifestations, imaging features, histopathological features, diagnostic pitfalls, treatment and prognosis of clear cell chondrosarcoma (CCCS).Methods:23 cases of CCCS admitted and operated from January 2010 to January 2020 were analyzed retrospectively. Among the 23 cases, 21 were males and 2 were females. There were 8 cases (35%) aged 21-40, 10 cases (43%) aged 41-60 and 5 cases (23%) aged 61-80. There were 8 femurs, 7 pelvis, 4 thoracolumbar spine, 3 sacrum and 1 tibia. The specimens were fixed with 10% phosphate-buffered formalin, decalcified with 5% nitric acid, embedded in paraffin and stained with hematoxylin and eosin (HE) and immunohistochemistry (Envision). The preoperative imaging and clinical symptoms, and the postoperative histopathological and immunophenotype under the microscope were collected. And the relevant literature was reviewed to summarize the clinical, imaging and pathomorphological characteristics of CCCS.Results:23 cases of CCCS showed bone destruction in imaging, some cases were well-circumscribed lytic lesions, some cases had sclerotic margin. The serum alkaline phosphatase was increased in 7 patients before operation. The tumor tissue was gray-white and gray-red in general and some cases showed porcelain white cartilage-like areas. Microscopically, the tumor cells are round or polygonal, some of them have clear cytoplasm and boundary, some of them are eosinophilic, some of them have round and centrally located nuclei, and mitotic image is rare. It is often seen that there are nodular distribution of cartilage-like matrix and immature woven bone, multinucleated osteoclast-like giant cell scattered in those components. Immunohistochemical staining: S-100, D2-40, EMA, Vimentin, p16, SATB2 can be positive in varying degrees. The surgical treatment is mainly through en bloc excision. 10 patients had recurrence and no distant metastasis.Conclusion:CCCS is a rare subtype of chondrosarcoma, which has low-grade malignant biological behavior and is easy to be misdiagnosed clinically and pathologically. Pathological diagnosis needs to be careful. Careful observation of microscopic histology is necessary in order to avoid over-diagnosis of osteosarcoma leading to clinical treatment errors. Once the biopsy is confirmed, it needs en bloc excision in order to reduce the recurrence rate. Long-term follow-up is needed after the operation, the overall prognosis was good.

Objective To analyze the molecular epidemiology of adenovirus ( ADV) causing acute respiratory diseases and to investigate the mixed infection of ADV and other respiratory pathogens in Hebei Province. Methods Sputum samples were collected from inpatient children with acute respiratory diseases at Children′s Hospital of Hebei Province between June 2017 and May 2018. Multiplex reverse transcription PCR assay was used to detecte 13 kinds of respiratory pathogens. Nested PCR was performed to amplify ADV hexon gene and the amplified products were then sequenced. Results A total of 353 ADV-positive speci-mens were detected in 8839 specimens with a positive rate of 3. 99％. Significant difference in the positive rate of ADV was not observed between male and female patients (χ2=0. 0003, P=0. 99), but found among different age groups (χ2=115. 69, P<0. 001). All isolated ADV strains belonged to 11 serotypes, which were type 1 (16. 15％, 57/353), type 2 (35. 98％, 127/353), type 3 (21. 25％, 75/353), type 4 (1. 13％, 4/353), type 5 (11. 33％, 40/353), type 6 (3. 97％, 14/353), type 7 (8. 22％, 29/353), type 31 (0. 28％, 1/353), type 41 (0. 28％, 1/353), type 55 (0. 28％, 1/353) and type 57 (1. 13％, 4/353). Among the 353 ADV-positive specimens, 259 were mixed infections mainly caused by ADV and human rhinovirus (35. 52％). ADV and respiratory syncytial virus co-infections accounted for 12. 74％ and 33. 20％ of the mixed infections involved three or more pathogens. ADV could be detected throughout the year, especially in September and April to May. The predominant serotypes were types 1, 2 and 3. The av-erage ages of the two groups of ADV infection alone and ADV mixed infection were (27. 56±24. 67) months and (21. 33 ±20. 28) months, respectively, and the difference between them was statistically significant (P=0. 037). The incidence of ADV 2 infection alone was 25. 77％ (25/97), which was lower than that of ADV 2-involved mixed infection [39. 84％ (102/256),χ2=6. 05, P=0. 014]. However, the rate of ADV 7 infection alone was significantly higher than that of ADV 7-involved mixed infection [16. 49％ 16/97) vs 5. 08％ (13/256),χ2=6. 05, P<0. 001]. Conclusion ADV 1, ADV 2 and ADV 3 were the predominant serotypes circulating in Hebei Province from June 2017 to May 2018, especially in September and April to May. The younger the patients were, the higher the incidence would be. ADV 2 was prone to cause mixed infections with other respiratory pathogens, while ADV 7 was less common in mixed infections. Younger pa-tients were more susceptible to mixed infections. The most common co-infection was caused by ADV and hu-man rhinovirus.

Objective To examine the sleep status and relevant psychosocial factors in patients with colorectal cancer before surgery and improve their sleep quality. Methods A cross?sectional survey method was used. Participants were 107 cases of patients with colorectal cancer from the Department of Anorectal Surgery in The First Hospital ,which is affiliated with China Medical University. The Athens insomnia scale(AIS),Ham?ilton depression scale(HAMD),Hamilton anxiety scale(HAMA),perceived social support scale(PSSS),self?esteem scale(SES),medical cop?ing questionnaire(MCMQ),memorial University of Newfoundland scale of happiness(MUNSH),Eysenck personality questionnaire(EPQ),and Wong?Baker face scale were used to assess preoperative sleep in patients with colorectal cancer and related psychosocial factors. Results Among the 107 cases,there were 24 cases of insomnia,with an insomnia incidence of 22.43%. No statistical differences were found in demographic charac?teristics and clinical characteristics(P>0.05). According to the degree of insomnia,there were significant differences between groups(P<0.05) for depression,anxiety,social support,avoidance,yield,happiness,and EPQ?N. Before the surgery,the degree of depression,anxiety,and EPQ?P had a significant positive effect on the degree of insomnia (P< 0.05). Conclusion The degree of insomnia before surgery in patients with colorectal cancer is closely associated with depression,anxiety,coping styles,social support,and personality characteristics.

Objective To evaluate the reliability and validity of the Reflective Function Questionnaire for Youth(RFQY). Methods School sample:a total of 1 813 students from the fifth grade primary school to the second grade high school were selected for the study(aged 10 to 17 years). Clinical patients:another 52 adolescents(aged under 17 years)with borderline trait who attended Department of Psychiatry in Shengjing Hospital were recruited. All subjects completed the RFQY,basic empathy scale( BES )and emotional intelligence scale(EIS). After 3 weeks,85 students were randomly selected and filled in the questionaires again. Results The internal consistency of the RFQY was 0.73,and the test?retest reliability was 0.686(P<0.001). The RFQY scores of the school students were significantly higher than those in clinical patients(8.71±0.65 vs 8.10±0.89,P<0.001). The RFQY scores of male students were significantly lower than those in female students(8.61±0.67 vs 8.78±0.63,P<0.001). The score increased with the age increased(P<0.001). Conclusion The Chinese version of RFQY shows good reliability and validity , which can be used to measure the reflective function of adolescents in China .

Objective To investigate the correlation between the expression of peripheral blood CD8 + T lymphocytes and the severity degree of hand,foot and mouth disease( HFMD)in children infected by enterovirus( EV)71 at different ages,and further to predict the role of the expression of CD8+ T lympho-cytes played in the occurrence of neurological complications infected by EV71. Methods A total of 138 pe-ripheral blood samples derived from the confirmed HFMD cases were collected in the department of infectious disease at Kunming Children′s Hospital between March and September in 2014,including 33 mild cases,45 severe cases,and 60 critical cases. Patient ages were 9 months to 5 years old. Flow cytometry was used to detect the expression of peripheral blood CD8 + T lymphocytes in all of above patients. Results Compared to the reference value of CD8 + T lymphocytes in normal healthy children at different age groups,the percentage of peripheral blood CD8 + T lymphocytes elevated or increased slightly in patients of all ages,except the obvi-ously increasing expression in the age group of ~2 years and decreasing expression in critical cases of the age group of ~5 years. The expression of peripheral blood CD8+ T lymphocytes significantly increased in mild and severe patients but slightly increased in critical patients of the age group of 9 to 15 months,gradually de-creased in the age group of ~2 years and slightly increased in mild and severe cases but decreased in critical patients of the age group of ~5 years. There were significant differences between the patients in mild condi-tion and in severe condition or critical condition respectively within the age group of ~2 years( P﹤0. 05 ), and there were no significant differences in other age groups between different severity of disease. Conclusion
There are correlations between the expression of CD8+ T cells and the severity of HFMD in patients at different ages. Especially,the patient′s condition developing into severe degree is associated with the rapid decreasing of CD8 + T cells in HFMD patients of the age group of ~2 years. CD8+T cells play an important role in antiviral immune response in HFMD patients of ~2 years old.
