It's difficult to diagnose precancerous lesion and early cancer for a long time, because both of them haven't typical morphological characteristics. As a novel diagnostic modality, fluorescence endoscopy can accurately reflect minimal changes in human's tissue, thus making a meaningful progress for cancer diagnosing. 200 patients were examined by fluorescence endoscopy to evaluate the diagnostic value. The overall accuracy, sensitivity and specificity for detecting malignant gastrointestinal tumor was 94.0%, 94.6% and 93.5%, respectively. Thus, fluorescence endoscopy can be used to diagnose malignant gastrointestinal tumors with high validity and reliability, and is advantageous over conventional white light endoscopy especially in detecting the atypical and suspicious lesions. Furthermore, fluorescence endoscopy can also guide target biopsy, is significant to improve the early cancer detection rate, has a broad development prospect.

Objective To investigate the effect of infiltrated mast cells on the biological characteristics of uterine carcinoma.Methods Twelve leiomyomas,ten uncertain malignant uterine leiomyomas,and seven uterine leiomyosarcomas were studied with light microscopy for the morphometry about their histological feature,mast cell particle and factor Ⅷ-related antigen(FⅧRAg);Cell apoptosis was measured by flow cytometry.The correlative analysis was carried out between the mast cell and others factors.Results Comparing with smooth muscle tumors of uncertain malignant potential(4209.9?273.0),the count of tumor cell was the highest in leiomyosarcoma(3557.6?346.3)(P

The mechanism and principles of autofluorescence imaging based on autofluorescence technique are reported. The threshold value of fluorescence spectrum ratio applied can be quantitative and objective and the reliable measurement method that may provide intuitive method of autofluorescence imaging in the gut mucosa. The suspected lesion may be found rapidly according to the imaging color difference, therefore the results of clinical study of the digestive tract cancer diagnosis indicated that the sensitivity, specificity, and diagnostic accuracy were 94%, 95.5% and 94.8% respectively, and it has very high value in clinical application.

Objective To analyze the current situation and latent profiles of nurses'voice behavior in nurses,and explore the influencing factors of different types.Methods Through convenience sampling,812 nurses who worked in tertiary hospitals from 5 cities in Guangdong Province during April 2022 to June 2022 were recruited.The demographic questionnaire,the Voice Behavior Scale,the Humble Leadership Scale,and the Team Psychological Safety Climate Scale were used for investigation.Latent profile analysis was used to explore the latent profiles of nurses'voice behavior.The influencing factors of latent profiles were identified by multivariate Logistic regression.Results The total score of the voice behavior in 812 nurses is(37.04±5.88).Voice behaviors in nurses is divided into 3 latent classes,namely"conservation group"(27.83％),"balanced-risky group"(61.95％),and"the challenge group"(10.22％).The influencing factors include recruitment type,whether to assist in department management,humble leadership,team psychological safety climate(all P＜0.05).Conclusion The level of nurses'voice behavior is upper medium with heterogeneity,which can be divided into 3 latent profiles.Nurses managers should focus on nurses with conservation group and balanced-risky group and conduct early targeted prevention and care according to characteristics and influencing factors of different latent profile.

In this paper, combined with the characteristics of rotational learning of dermatologists, we have taken various measures such as improving the scientific research training system, strengthening the awareness of scientific research, optimizing the teaching mode, adding new assessment mechanism, hand-in-hand teaching and other measures to realize the close combination of clinical and scientific research, and lay a solid foundation for the cultivation of high-quality innovative talents in dermatology.

Objective:To explore the clinical application value of general coagulation indices and neutrophil-to-lymphocyte ratio (NLR) for assessing coagulation status of patients with ovarian cancer.Methods:The data of 190 patients with ovarian cancer who were admitted to the Second Hospital of Shanxi Medical University from October 2019 to September 2022 were retrospectively analyzed. According to the International Federation of Gynecology and Obstetrics (FIGO) staging, the patients were divided into early (stage Ⅰ-Ⅱ) ovarian cancer group (70 cases) and advanced (stage Ⅲ-Ⅳ) ovarian cancer group (120 cases). Forty-four patients with benign ovarian tumors who were treated in the Second Hospital of Shanxi Medical University during the same period were selected. Plasma D-dimer (D-D), activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB) and thrombin time (TT) were tested. Platelet count (Plt), neutrophil count and lymphocyte count were measured by blood cell analyzer, and NLR was calculated. The receiver operating characteristic (ROC) curve was used to analyze the value of coagulation indices and NLR in the assessment of venous thromboembolism (VTE) in patients with ovarian cancer.Results:Compared with the benign ovarian tumor group, PT of patients in the early and advanced ovarian cancer groups was shorter (both P < 0.05), and D-D and Plt increased (both P < 0.05). Compared with the benign ovarian tumors group, TT of patients in the advanced ovarian cancer group decreased ( P < 0.05), and FIB and NLR increased (both P < 0.05). Compared with the early ovarian cancer group, PT and TT in the advanced ovarian cancer group were shorter (both P < 0.05), and FIB, D-D, NLR and Plt increased (all P < 0.05). The optimal cut-off values of FIB, D-D and NLR in stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients with VTE in ovarian cancer group were 3.165, 333.500 and 2.455, and the area under the curve (AUC) was 0.731, 0.837 and 0.759. Conclusions:The coagulation indices of patients with ovarian cancer are abnormal during treatment, suggesting that patients may produce active thrombosis, and the symptoms of patients in advanced stage are more serious.
