Objective:To explore the latent profiles of intellectual humility in primary colorectal cancer (CRC) postoperative patients and analyze the correlation between their intellectual humility and self-management.Methods:A total of 250 patients with primary CRC who underwent radical tumor surgery in anorectal department of Qinghai Provincial Hospital of Traditional Chinese Medicine from October 2021 to June 2023 were selected to accept a cross-sectional survey through convenient sampling method. They were surveyed by basic information questionnaire, comprehensive intellectual humility scale and cancer patient self-management assessment scale.Results:Finally, 243 valid questionnaires were obtained, it contained 125 males and 118 females with age 32- 68 (52.45 ± 10.24) years old. The score of primary CRC postoperative patients′intellectual humility was (67.59 ± 13.26) points, it could be divided into low-level intellectual humility type with 30 cases(12.34%), confident intellectual humility type with 36 cases (14.82%), mid-level intellectual humility type with 93 cases (38.27%), and high-level intellectual humility type with 84 cases (34.57%). Disordered multi-classes Logistic regression analysis showed that gender(female, OR=2.465), education level (high school or vocational school, OR=0.012) and diagnosis time(1-3 months, OR=15.289) were significant influencing factors to primary CRC postoperative patients from confident intellectual humility type (all P<0.05), gender (female, OR=5.354) and education level (high school or vocational school education, OR=0.012) were significant influencing factors to primary CRC postoperativepatients from mid-level intellectual humility type (both P<0.05), gender (female, OR=11.253), age (<45 years old, OR=7.532), education level (high school or vocational school, OR=0.017) and diagnosis time (<1 month, OR=0.054) were significant influencing factors to primary CRC postoperative patients from high-level intellectual humility type (all P<0.05). The score of primary CRC postoperative patients′self-management was (142.03 ± 19.83) points. There were statistically significant differences among scores of self-management, daily life management, symptom management and other six dimensions in patients from different categories of intellectual humility ( F values were 25.42-490.55, all P<0.05). There were positive correlation between the CRC patients′inteilectual humility and postoperatice self-managemeat ( r values were 0.373 - 0.749, all P<0.05). Conclusions:Primary CRC patients have a moderate level of knowledge humility and postoperative self-management. Their knowledge humility can be divided into low knowledge humility type, confident knowledge humility type, medium knowledge humility type, and high knowledge humility type. Knowledge humility can enhance postoperative self-management, and targeted interventions should be carried out for CRC patients with different types of knowledge humility to provide them with better cancer care and enhance their self-management level.

Objective:To investigate the effect of different cleaning methods on the cleaning effect of Da Vinci robotic electrosurgical instruments and the feasibility of adenosine triphosphate(ATP) fluorescence detection technology for evaluating the cleaning effect of Da Vinci robotic electrosurgical instruments.Methods:A total of 180 electrosurgical instruments were divided into control group and test group by random digits table method from June 2018 to June 2019 after robotic surgery. For the control group, 90 cases were manually cleaned to complete the device cleaning process, and for the test group, 90 cases were mechanically cleaned to complete the device cleaning process. Through visual observation, magnifying glass examination and ATP fluorescence detection technology, the cleaning effect of the two methods and the correlation between the evaluation results obtained by ATP fluorescence detection technique and traditional inspection method were compared.Results:The qualified rate of visual observation, magnifying lens examination and ATP fluorescence detection in the control group were 95.56%(85/90), 86.67% (78/90) and 84.44% (76/90), respectively, and that in the test group were 100.00% (90/90), 97.78% (88/90) and 98.89% (89/90), respectively. The test group was higher than the control group. The difference between the two groups was statistically significant ( χ2 values were 4.310, 7.745, 12.291, P<0.05 or 0.01). In the control group, there was a positive correlation between the qualified rate of ATP fluorescence detection and visual observation ( r value was 0.374, P < 0.01), and a significant positive correlation between the qualified rate of magnifying lens examination ( r value was 0.538, P < 0.01). In the test group, There was also a significant positive correlation between the qualified rate of ATP fluorescence detection and visual observation ( r value was 0.754, P < 0.01), and between the qualified rate of magnifying lens examination( r value was 0.556, P < 0.01). Conclusions:Mechanical cleaning is used to clean Da Vinci robotic electrosurgical instruments, which is superior to traditional manual cleaning. ATP fluorescence detection technology is feasible for evaluating the cleaning effect of Da Vinci robotic electrosurgical instruments.

Trichinella spiralis,Ascaris lumbricoides,and Taenia crassiceps are all parasitic helminths that can infect humans.After invading host,the parasites can induce immune responses such as activation of immune cells and induction of cytokines in the host.The immune responses induced by parasitic helminths have similarities with anti-tumor immune responses.Recent studies have demonstrated that infection of Trichinella spiralis,Ascaris lumbricoides,or Taenia crassiceps can inhibit the development of several kinds of tumors to some extent.In this paper,the progress of anti-tumor effects induced by the above-mentioned helminths on liver cancer,lung cancer,breast cancer,malignant melanoma,myeloma,and other cancers is reviewed,which may provide a valuable reference for treatment of tumors by the immune response to helminthic infection.

Objective To study the diagnostic value and clinical efficacy of endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA ) for mediastinal and abdominal lymphadenopathy. Methods Thirty patients who underwent EUS-FNA for mediastinal or abdominal lymphadenopathy between May 2009 and December 2015 were reviewed. The clinical efficacy of EUS-FNA was evaluated by pathological results and the follow-up. The EUS-FNA effect on clinical decision was also analyzed. Results Lesions were located in the mediastinum in 10 cases and in the abdomen in 20 cases. The total diagnostic accuracy, sensitivity, specificity, positive predictive value ( PPV) and negative predictive value ( NPV) of EUS-FNA were 96. 7%, 94. 7%, 100. 0%, 100. 0% and 91. 7%, respectively. Of all the 30 cases, 20 lymph glands were of unknown origin. The diagnostic accuracy, sensitivity, specificity, PPV and NPV of EUS-FNA in these lesions were 95. 0%, 88. 9%, 100. 0%, 100. 0% and 91. 7%, respectively. The combination of cytological and histological examination had higher accuracy ( 96. 7% VS 73. 3%, P=0. 026) and sensitivity ( 94. 7%VS 57. 8%, P= 0. 019 ) than cytological examination only. Immunohistochemistry stains were performed in 12 neoplastic cases, and 11 ( 91. 7%) were confirmed. The diagnosis by EUS-FNA had positive impact on clinical decisions in 27 patients ( 90. 0%) . Conclusion EUS-FNA is an effective approach for mediastinal and abdominal lymphadenopathy, and the result has a positive impact on clinical decisions. The combination of cytological and histological examination and application of ancillary techniques, such as immunohistochemistry stains, can improve the diagnostic efficacy of EUS-FNA.
