Objective To investigate the cognition of colorectal cancer-related knowledge and influencing factors of patients with middle- and advanced-stage colorectal cancer in ethnic minority areas of Inner Mongolia. Methods According to the national population and the prevalence of colorectal cancer, 277 patients with colorectal cancer were selected by stratified and random sampling in Inner Mongolia. The patients were surveyed in Baotou, Chifeng, Bayannaoer, and other hospitals. The questionnaire included patients' basic information, cognition of colorectal cancer risk factors and screening knowledge, screening information, etc. Results Before suffering from the disease, the patients' knowledge of colorectal cancer (risk factors, early screening knowledge, treatment methods) was low. About 54.9% of patients were unaware of high risk factors for colorectal cancer, 75.8% of patients did not understand the knowledge of early screening of colorectal cancer, and 37.5% of patients did not underst and the treatment of colorectal cancer. The main influencing factors of colorectal cancer cognition were education level and occupation. Patients who work in institutions and enterprises and with higher education level had better cognition. Conclusion Patients with middle- and advanced-stage colorectal cancer in Inner Mongolia have poor knowledge and awareness of risk factors and screening of colorectal cancer before diagnosis. Education level and occupation are factors influencing colorectal cancer cognition, therefore, people with low knowledge rate of colorectal cancer and low education level as well as unemployed laid-off people should be given priority intervention.

Objective To understand and evaluate the knowledge, attitude and practice of female human papillomavirus and HPV vaccine in Chinese mainland. Methods We searched the relevant studies about the knowledge, attitude and behavior factors of HPV infection and HPV vaccine published in PubMed, MEDLINE, CNKI and Wanfang databases about Chinese mainland women from January 1, 1995 to January 31, 2021.Two researchers independently screened the literatures, extracted data and the literatures with quality score≥5 points.Chi square test was used to evaluate its heterogeneity.Begg' s test was used to evaluate publication bias. Results A total of 33 literatures were included, with a total number of 46013 people.The results showed that the total awareness rate of HPV in the population was 65.9%, the lowest rates were 16.0%, 41.2% and 14.4% in Northeast, rural areas and middle school students, respectively; while the highest rates of HPV were 77.4%, 56.3% and 71.0% in Central China, cities and towns and college students, respectively.The main source of HPV knowledge was the network/WeChat official account number (38.9%), and the lowest was family/friend (4.5%).The population's awareness rate of HPV vaccine related knowledge was 41.4%, the highest rates were 51.8% and 69.7% in East China and medical staff, respectively, while the lowest were 23.6% and 12.7% in Southwest and middle school students. Conclusion In order to achieve the total elimination of cervical cancer in China by 2030 as soon as possible, people should strengthen their awareness of HPV and HPV vaccine related knowledge.

Objective:To explore the changes of brain activity in drug-resistant or drug-controlled medial temporal lobe epilepsy patients by the method of functional connectivity density (FCD), and to analyze their correlation with the course of the disease.Methods:According to the definition of drug-resistant epilepsy by the International League Against Epilepsy in 2010, 146 patients with medial temporal lobe epilepsy who were clearly diagnosed as unilateral hippocampal sclerosis in Jinling Hospital, Nanjing University School of Medicine from July 2009 to February 2019 were divided into drug control group ( n=73) and drug-resistant group ( n=73). The 3.0 T resting state functional magnetic resonance scan was performed on all subjects to compare the difference in FCD between the two groups, and calculate the correlation between the FCD value of the brain area and the course of the disease between the two groups of patients. Results:There was significant difference between the two groups in FCD. Compared with the drug control group, the drug-resistant group had significantly lower FCD values in the insula, lenticular nucleus, thalamus, hippocampus and precentral gyrus on the side of the epileptogenic focus. The FCD value of the precuneus on the side of the epileptogenic focus in the drug-resistant group was negatively correlated with the duration ( r=-0.30, P=0.01). Conclusions:The FCD of patients with drug-resistant medial temporal lobe epilepsy was lower than that of the drug control group. In addition, there may be progressive damage to the brain. The difference is helpful for exploring the pathophysiological mechanisms related to drug resistance in patients with medial temporal lobe epilepsy, and finding reliable neuroimaging markers related to drug resistance.

Objective:To construct a multi-label learning MRI model for assisting diagnosis of sports injury in knee.Methods:A total of 1 391 knee MRI cases from 1 343 young adults with sports injury in Affiliated Jinling Hospital Nanjing University School of Medicine were retrospectively enrolled. The image cases were randomly divided into training set ( n=973), validation set ( n=139) and test set ( n=279) with ratio of 7∶1∶2. The knee injuries were divided into six categories: meniscus injury, tendon injury, ligament injury, osteochondral injury, synovial bursa disorder and soft tissue injury. Using PyTorch V1.1.0 algorithm package, the Yolo model of deep learning was used to construct the MRI knee joint sports injury detection model. The model was validated on the test set, and the sensitivity, specificity and mean average precision of lesion detection were evaluated. Results:Among the 279 patients in test set, the mean average precision of meniscus injury, tendon injury, ligament injury, osteochondral injury, synovial bursa disorder and soft tissue injury were 83.1%, 89.0%, 88.0%, 85.8%, 85.5% and 83.2%, respectively, and the overall mean average precision was 85.8%. The model was most effective in detecting tendon injury. The sensitivity and specificity of the model for tendon injury were 91.2% and 87.1% respectively.Conclusions:The multi-label MRI knee joint exercise-related injury detection model based on deep learning can effectively assist in detecting the exercise-related injury of knee joint in each tissue structure, and is expected to improve the efficiency of diagnosis and treatment in orthopedics.

Objective To investigate the effect of SABP, a water-soluble component of Salvia miltiorrhiza, on the growth of orthotopic transplantation of H22 liver cancer and the immune microenvironment of liver cancer. Methods We established a mouse model of orthotopic transplantation of H22 cell liver cancer in BALB/c mice. ELISA was used to detect the expression of PD-L1, TGF-β, IL-1β, IL-10, IL-4, IFN-γ, IL-18, IL-7, IL-2, CCL-2 and CCL-21 in the liver. We counted the organ indexes of liver, spleen and kidney. Results SABP inhibited the growth of orthotopic transplantation tumors of H22 cell liver cancer, and increased the expression levels of PD-L1, TGF-β, IL-1β and IL-10 in the microenvironment of liver cancer, as well as the liver, spleen and kidney coefficients. Conclusion SABP could inhibit the growth of orthotopic transplantation tumors of H22 cell liver cancer and promote the expression of PD-L1, TGF-β, IL-1β and IL-10 in the microenvironment of liver cancer.

Objective To investigate the effect and mechanism of suberoylanilide hydroxamic acid (SAHA) on the fear extinction in mice with chronic social defeat stress (SD). Methods Fifty-six male C57BL/6J mice aged 7-8 weeks were randomly divided into control group,social defeat group,control-SAHA group and social defeat-SAHA group to investigate the effect of SAHA and social defeat group,social defeat-AAV BDNF group and social defeat-AAV blank group to investigate the effect of BDNF. Fear extinction in mice was evaluated by fear conditioning test (FC). The levels of BDNF and HDAC2 in mice hippocampus were detected by Western blot (WB). The expression of BDNF-overexpressing virus in hippocampus of mice was detected by immunofluorescence assay. Results (1) Compared with control group,fear extinction in the social defeat group was significantly decreased (P<0. 05). Compared with control group, the level of HDAC2(0. 50±0. 02) in the social defeat group was significantly increased (P<0. 001),while the level of BDNF(0. 16 ± 0. 03) was significantly decreased (P<0. 001) in the social defeat group. ( 2) After using SAHA,fear extinction of mice significantly improved (P<0. 05). Compared with control group,the level of HDAC2 (0. 26±0. 02) in the control-SAHA group was significantly decreased(P<0. 001),and the level of BDNF (0. 40±0. 03) was significantly increased (P<0. 001). Compared with social defeat group,the level of HDAC2 (0. 39±0. 03) in the social defeat-SAHA group was significantly decreased (P<0. 001),and the lev-el of BDNF (0. 28±0. 01) was significantly increased (P<0. 001). (3)After injection BDNF-overexpressing virus,fear extinction was significantly improved(P<0. 05). Conclusion SAHA can enhance fear extinction in mice with chronic social defeat stress and its mechanism may be related to the up-regulation of BDNF ex-pression in hippocampus by inhibiting HDAC2 in hippocampal.
