Objective To explore the correlation between intestinal dose and acute radiation enteritis(ARE)in patients with cervical cancer received concurrent chemoradiotherapy,and optimize the dose limit of intestinal tissue.Methods 158 cervical cancer patients received concurrent chemoradiotherapy from 2014 to 2019 were selected in this study.According to CTCAE 5.0,patients with ARE≥grade 2 were classified as ARE≥grade 2 group,otherwise classified as ARE0.7,P<0.05).Conclusions For patients with cervical cancer received concurrent chemoradiotherapy,the dose of bowelbag V5 and V40 should be considered to rationally optimize the dose of bowelbag in the radiotherapy plan,so as to reduce the incidence of ARE≥grade 2.

Objective To evaluate the effectiveness of tumor cell Vimentin combined with endoscopic ultrasound-guided fine-needle biopsy(EUS-FNB)in diagnosing solid pancreatic tumors.Methods Clinical data from 110 patients who underwent EUS-FNB from October 2021 to December 2023 were retrospectively analyzed.Solid pancreatic tumors including but not limited to pancreatic cancer and pancreatic neuroendocrine tumors.The sensitivity,specificity,and accuracy of EUS-FNB were assessed by comparing its results with the final pathological diagnoses.Result Clear histopathological diagnoses were obtained in 106 cases,accounting for 96.37%.Among them,87 cases were definitively diagnosed as adenocarcinoma or pancreatic ductal adenocarcinoma.Immunohistochemical staining showed that Vimentin was expressed in the tumor cells.There was no statistically significant difference in positive rates among biopsies from different anatomical sites(P>0.05),but significant differences were observed in lesions of different diameters(P<0.05).Immunohistochemical staining suggested that Vimentin expression levels might be associated with the nature of the lesions.The overall diagnostic accuracy,sensitivity,and specificity of Vimentin combined with EUS-FNB for pancreatic masses were 86.09%,84.57%,and 100.00%,respectively.Specifically,for solid masses,the diagnostic accuracy,sensitivity,and specificity were 87.67%,86.55%,and 100.00%,respectively.For pancreatic cystic tumors,the diagnostic accuracy,sensitivity,and specificity were 65.42%,69.79%,and 100.00%,respectively.Conclusion The combination of tumor cell Vimentin and EUS-FNB demonstrates high diagnostic accuracy for solid pancreatic tumors,making it a valuable tool for clinical application.

ObjectiveTo systematically analyze international disability data policies and standards, as well as the application of disability data in policymaking, service optimization and inclusive social development, and to clarify the importance of international disability data policies, standard systems and disability data application for the development of disability-related services. MethodsThrough the analysis of policy content and research on the data standard system, this study explored the disability data policy framework, standard system and technical path of data interoperability and integration of international organizations including the United Nations (United Nations Statistics Division and United Nations Children's Fund), World Health Orgnization, United Nations Educational Scientific and Cultural Organization, and International Labour Organization. ResultsInternational organizations established disability data policy frameworks based on their respective mandates, involving data and service development, data standards, data governance, and data application. The international community established a disability data standard system for disability data collection, coding, exchange, interoperability, statistical analysis, data fusion and application. Building a standardized disability data standard system based on the framework of international health classification standards such as International Classification of Functioning, Disability and Health, and International Classification of Diseases, Eleventh Revision would ensure the consistency of cross-national disability data policies, and the interoperability and comparability of disability data, promoting the development of data-driven disability-related services, accurately identifying the service needs of people with disabilities, and optimizing service provision, thereby improving the quality of life and social participation of people with disabilities. ConclusionThe construction and implementation of international disability data policies and data standards have promoted the standardization and interoperability of disability data. With the application of big data, artificial intelligence and blockchain technologies in disability data, international cooperation and cross-industry data fusion in the field of disability data have been promoted, further promoting the development of data-driven disability services, ensuring equal opportunities for people with disabilities to enjoy service resources, and improving the coverage and quality of disability services.

Background/Aims: To evaluate the causal correlation between complement components and non-viral liver diseases and their potential use as druggable targets. Methods: We conducted Mendelian randomization (MR) to assess the causal role of circulating complements in the risk of non-viral liver diseases. A complement-centric protein interaction network was constructed to explore biological functions and identify potential therapeutic options. Results: In the MR analysis, genetically predicted levels of complement C1q C chain (C1QC) were positively associated with the risk of autoimmune hepatitis (odds ratio 1.125, 95% confidence interval 1.018–1.244), while complement factor H-related protein 5 (CFHR5) was positively associated with the risk of primary sclerosing cholangitis (PSC;1.193, 1.048– 1.357). On the other hand, CFHR1 (0.621, 0.497–0.776) and CFHR2 (0.824, 0.703–0.965) were inversely associated with the risk of alcohol-related cirrhosis. There were also significant inverse associations between C8 gamma chain (C8G) and PSC (0.832, 0.707–0.979), as well as the risk of metabolic dysfunction-associated steatotic liver disease (1.167, 1.036–1.314). Additionally, C1S (0.111, 0.018–0.672), C7 (1.631, 1.190–2.236), and CFHR2 (1.279, 1.059–1.546) were significantly associated with the risk of hepatocellular carcinoma. Proteins from the complement regulatory networks and various liver diseaserelated proteins share common biological processes. Furthermore, potential therapeutic drugs for various liver diseases were identified through drug repurposing based on the complement regulatory network. Conclusions Our study suggests that certain complement components, including C1S, C1QC, CFHR1, CFHR2, CFHR5, C7, and C8G, might play a role in non-viral liver diseases and could be potential targets for drug development.

Objective:To investigate the safety and feasibility of the CHESS endoscpic ruler (CHESS ruler), and the consistency between the measured values and the interpretation values by endoscopic physician experience.Methods:From January 2021 to January 2022, a total of 105 liver cirrhosis patients with portal hypertension were prospectively enrolled from General Hospital, Xixia Branch Hospital, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region (29 cases), and the First People′s Hospital of Yinchuan (25 cases), General Hospital of Ningxia Medical University (18 cases), Wuzhong People′s Hospital (10 cases), the Fifth People′s Hospital of Ningxia Hui Autonomous Region (10 cases), Shizuishan Second People′s Hospital (6 cases), Yinchuan Second People′s Hospital (5 cases), and Zhongwei People′s Hospital (2 cases) 8 hospitals. The clinical characteristics of all the patients, including gender, age, nationality, etiolog of liver cirrhosis, and Child-Pugh classification of liver function were recorded. A big gastroesophageal varices was defined as diameter of varices ≥5 mm. Endoscopist (associated chief physician) performed gastroscopy according to the routine gastroscopy procedures, and the diameter of the biggest esophageal varices was measured by experience and images were collected, and then objective measurement was with the CHESS ruler and images were collected. The diameter of esophageal varices of 10 randomly selected patients (random number table method) was determined by 6 endoscopists (attending physician or associated chief physician) with experience or measured by CHESS ruler. Kappa test was used to test the consistency in the diameter of esophageal varices between measured values by CHESS ruler and the interpretation values by endoscopic physician experience.Results:Among 105 liver cirrhosis patients with portal hypertension, male 65 cases and female 40 cases, aged (54.8±12.2) years old, Han nationality 82 cases, Hui nationality 21 cases and Mongolian nationality 2 cases. The etiology of liver cirrhosis included chronic hepatitis B (79 cases), alcoholic liver disease (7 cases), autoimmune hepatitis (7 cases), chronic hepatitis C (2 cases), and other etiology (10 cases). Liver function of 32 cases was Child-Pugh A, Child-Pugh B 57 cases, and Child-Pugh C 16 cases. All 105 liver cirrhosis patients with cirrhotic portal hypertension were successfully measured the diameter of gastroesophageal varices by CHESS ruler, and the success rate of application of CHESS ruler was 100.0% (105/105). The procedure time from the CHESS ruler into the body to the exit of the body after measurement was (3.50±2.55) min. No complications happened in all the patients during measurement. Among 105 liver cirrhosis patients with cirrhotic portal hypertension, 96 cases (91.4%) were recognized as big gastroesophageal varices by the endoscopists. Totally 93 cases (88.6%) were considered as big gastroesophageal varices by CHESS ruler. Eight cases were recognized as big gastroesophageal varices by the endoscopist, however not by the CHESS ruler; 5 cases were recognized as big gastroesophageal varices by the CHESS ruler, but not by the endoscopists; 4 cases were not recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler; 88 cases were recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler. The missed diagnostic rate of big gastroesophageal varices by the endoscopists experience was 5.4% (5/93), and the Kappa value of consistency coefficient between the measurement by the CHESS ruler and the interpretation by endoscopists experience was 0.31 (95% confidence interval 0.03 to 0.60). The overall Kappa value of consistency coefficient by 6 endoscopists measured by CHESS ruler in big gastroesophageal varices diagnosis was 0.77 (95% confidence interval 0.61 to 0.93).Conclusion:As an objective measurement tool, CHESS ruler can make up for the deficiency of subjective judgment by endoscopists, accurately measure the diameter of gastroesophageal varices, and is highly feasible and safe.

Objective:To evaluate the value of preoperative peripheral blood neutrophil-lymphocyte ratio (NLR) and blood platelet-lymphocyte ratio (PLR) and immune indexes in the evaluation of the prognosis of cervical cancer patients.Methods:The clinical data of 283 patients with cervical cancer who underwent radical surgery in Shanxi Province Cancer Hospital from May 2017 to September 2018 were retrospectively analyzed, and 100 healthy people who underwent physical examination during the same period were collected as the healthy control group. Test results of blood cells and immune cells expressions of all subjects were collected. Peripheral blood NLR and PLR of cervical cancer patients, people in the healthy control group and cervical cancer patients with different pathological characteristics were compared. Kaplan-Meier method was used to make survival analysis and Cox regression risk model was used to analyze the factors influencing the prognosis of patients with cervical cancer.Results:The preoperative peripheral blood NLR and PLR in patients with cervical cancer was higher than that of the healthy control group (NLR: 2.53±1.35 vs. 2.00±1.21, t = 5.35, P < 0.001; PLR: 163±57 vs.144±38, t = 4.71, P = 0.006). Pathological results showed that there were no statistically significant differences in NLR and PLR in peripheral blood of cervical cancer patients with different pathological types, tumor diameter, vascular invasion, and nerve invasion (all P > 0.05), while there were statistically significant differences in NLR and PLR in peripheral blood of cervical cancer patients with different clinical staging and muscle wall invasion (all P < 0.05). When the proportions of the expression levels of preoperative CD3 positive cells, CD4 positive cells, CD8 positive cells, CD19 positive cells, CD56 positive cells, and CD127 positive cells were 60%-85%, 30%-40%, < 25%, 8%-15%, 15%-25% and < 5%, respectively, the overall survival of cervical cancer patients was the best. Univariate analysis showed that pathological type, clinical staging, vascular invasion, preoperative NLR, preoperative PLR,CD3 positive cells, CD4 positive cells, CD8 positive cells, CD19 positive cells, CD56 positive cells and CD127 positive cells were influencing factors of the overall survival of cervical cancer patients (all P < 0.05). Multivariate analysis showed that clinical staging, vascular invasion, preoperative NLR, preoperative PLR, and preoperative CD4 positive cells were independent influencing factors for the overall survival of cervical cancer patients (all P < 0.05). Conclusions:Preoperative high NLR and PLR in peripheral blood have a certain impact on the clinicopathological characteristics and poor prognosis of cervical cancer patients. When the immune cells in peripheral blood are in dynamic balance, the prognosis of cervical cancer patients is the best.

End-stage renal disease (ESRD) patients undergoing outpatient hemodialysis (HD) and home peritoneal dialysis (PD) are high risk population of severe and critical types caused by SARS-CoV-2 infection. In order to improve the quality of diagnosis and treatment in dialysis patients with SARS-CoV-2 infection, we wrote this recommendation for primary care clinicians. During the epidemic period of SARS-CoV-2 infection, all patients should be instructed to strengthen self-management. Once the SARS-CoV-2 infection was found in dialysis patients, early stratified management should be carried out within 72 hours after the first positive nucleic acid or antigen test results, which includes early antiviral therapy, early recognition, and transferring severe patients from community or primary hospital to a referral hospital promptly. Guidance for dietary and sports rehabilitation after SARS-CoV-2 infection should also be started as soon as possible.

Objective:To explore the differences in clinicopathological features, survival status and prognostic influencing factors of breast cancer patients with different molecular subtypes, and to provide bases for the prevention and treatment of breast cancer.Methods:The clinicopathological data of new-onset female breast cancer patients hospitalized in Shanxi Province Cancer Hospital from January 2015 to December 2016 were retrospectively analyzed, and patients were followed up. The clinicopathological features of patients with different molecular subtypes were compared. The follow-up was performed until June 30, 2021. Kaplan-Meier method was used to analyze the survival of patients, and Cox proportional hazards model was used to analyze the factors affecting overall survival (OS) of patients with different molecular subtypes.Results:There were 272 (14.9%), 1 005 (55.2%), 277 (15.2%) and 268 (14.7%) patients with subtypes of Luminal A, Luminal B, human epidermal growth factor receptor 2 (HER2) overexpression and triple-negative breast cancer (TNBC), respectively. The differences in the distribution of patients with age at diagnosis, age at menarche, menopausal status, age at menopause, pathological type, longest tumor diameter, T staging, N staging, histological grading, and TNM staging were statistically significant among the four groups (all P < 0.05). At a median follow-up of 60 months, the 5-year OS rates of Luminal A, Luminal B, HER2 overexpression and TNBC subtypes were 93.8%, 89.2%, 77.6% and 78.0%, respectively, and the difference was statistically significant ( χ2 = 58.76, P < 0.001). M staging was an independent influencing factor for OS in patients with Luminal A breast cancer ( HR = 16.789, 95% CI 4.972-56.690, P < 0.001); T staging ( HR = 2.721, 95% CI 1.715-4.319), N staging ( HR = 4.460, 95% CI 2.399-8.291) and M staging ( HR = 3.364, 95% CI 1.988-6.670) were independent influencing factors for OS in patients with Luminal B breast cancer (all P < 0.001); N staging ( HR = 4.428, 95% CI 1.836-10.677) and M staging ( HR = 13.489, 95% CI 6.043-30.107) were independent influencing factors for OS of patients with HER2 overexpression breast cancer (both P < 0.01); T staging ( HR = 3.052, 95% CI 1.575-5.915), N staging ( HR = 2.492, 95% CI 1.298-4.785) and M staging ( HR = 33.012, 95% CI 8.606-126.637) were independent influencing factors for OS of patients with TNBC (all P < 0.01). Conclusions:The clinicopathological features and prognostic influencing factors of breast cancer patients with different molecular subtypes are different, and the prognosis of HER2 overexpression and TNBC patients is poor. Clinicians should provide individualized treatment and follow-up programs for patients with different molecular subtypes of breast cancer.

Objective:To investigate the association between breast cancer and thyroid diseases, and to provide evidence for the prevention and treatment of thyroid diseases in breast cancer patients.Methods:A total of 511 newly diagnosed breast cancer patients were recruited between March 2018 and August 2019 from Shanxi Province Cancer Hospital, and 303 age-matched newly diagnosed breast benign disease patients and 341 age-matched healthy controls were recruited during the same time-frame. Thyroid B-ultrasound and thyroid function test were performed in the three groups. By reviewing the medical records, the general and clinicopathological data of the patients were collected, and the differences in the prevalence of thyroid diseases among the three groups were compared. The changes of thyroid function in breast cancer patients before treatment, in the middle stage of chemotherapy and at the end of chemotherapy were compared.Results:Among breast cancer group, breast benign disease group and healthy control group, the differences in the prevalence rates of hypothyroidism [32.5% (166/511), 25.7% (78/303) and 21.7% (74/341)], thyroid nodules [50.7% (259/511), 43.2% (131/303) and 41.6% (142/341)] and Thyroid Imaging Reports and Data System(TI-RADS) grade 4 and above thyroid nodules [15.4% (40/259), 14.5% (19/131) and 4.9% (7/142)] were statistically significant (all P < 0.05). The abnormal rates of thyroid stimulating hormone (TSH) and free thyroxine (fT4) in breast cancer group were higher than those in breast benign disease group and healthy control group [34.1% (174/511) vs. 26.1% (79/303), 23.5% (80/341); 24.9% (127/511) vs. 8.6% (26/303), 3.2% (11/341)], and the differences were statistically significant (both P < 0.05). The levels of fT4, free three iodide thyroxine (fT3), thyroid immunoglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) in breast cancer patients before treatment, in the middle stage of chemotherapy and at the end of chemotherapy were statistically different (all P < 0.05). The abnormal rates of fT4, TgAb and TPOAb in the last chemotherapy cycle were lower than those before chemotherapy [11.5% (59/511) vs. 24.9% (127/511), 5.1% (26/511) vs. 17.4% (89/511), 11.9% (61/511) vs. 20.4% (104/511)] in breast cancer patients, and the differences were statistically significant (all P < 0.001). Conclusions:The breast cancer is associated with thyroid diseases. Clinicians should pay more attention to the changes of thyroid diseases and thyroid function during the treatment and in the follow-up process of breast cancer patients, so as to detect the thyroid diseases early and carry out standardized treatment.
