Objective:To investigate the alterations of brain functional network related to disease progression in patients with temporal lobe epilepsy (TLE) and the potential neural mechanism of executive dysfunction.Methods:Nineteen temporal lobe epilepsy patients with a disease course of less than or equal to 5 years (TLE-SD group) and 24 temporal lobe epilepsy patients with a disease course of more than 5 years (TLE-LD group) were recruited from the Epilepsy Clinic of the First Affiliated Hospital of Guangxi Medical University from December 2019 to December 2021. At the same time, 21 healthy control individuals (healthy control group) were recruited from the society and matched with gender, age, and education level. All subjects were evaluated demographic and clinical data, and performed resting state functional magnetic resonance imaging (rs-fMRI) and attention network test (ANT). The topological properties of functional brain network of 3 groups of subjects were calculated using graph theory, and then the hubs were determined. Then the inter-group comparison of hubs properties was carried out, and the correlation analysis with executive control function was performed.Results:The distribution pattern of hub nodes in TLE-SD patients was changed. Compared with the TLE-LD and healthy control groups, the TLE-SD group significantly increased the nodal degree values in brain regions such as the ventrolateral area of the left middle frontal gyrus, the left anterior central gyrus (upper limb area), the cephalic and caudal areas of the left parietal lobule, as well as the inner parietal lobe area, the caudal side of the right parietal lobule, and the right lateral occipital cortex. The nodal values of the brain areas such as the lateral and parietal inner area, the caudal side of the right upper upper lobule, and the right lateral occipital cortex were significantly increased. TLE-SD patients had a significant increase in the middle of the right upper frontal gyrus and the head of the left upper upper lobule. The node efficiency was significantly lower than that of TLE-LD patients, and the node efficiency in the middle of the right upper frontal gyrus was significantly lower than that of the healthy control group. The node network attributes of the left upper lobe were positively correlated with the execution control efficiency, and negatively correlated with the orientation efficiency. No significant difference was detected between TLE-LD patients and healthy controls.Conclusions:In TLE patients, the hubs in the middle of the right superior frontal gyrus were first damaged, and new hubs appeared in the dorsal attention network, the left anterior central gyrus and the right occipital lobe and were overloaded. With the progression of the disease, hubs tended to be redistributed to normality. The left superior parietal lobule may play an important role in the impairment of executive control function in TLE patients.

Objective:To establish the patient derived xenograft (PDX) model of liver malignant tumor, analyze the related factors affecting the carcinogenesis of PDX model, and analyze the differences of biological characteristics between the primary tumor and PDX model.Methods:Fresh liver malignant tumor tissue samples were collected from the patients who received the surgery from the Tianjin First Central Hospital and the samples were inoculated subcutaneously into BALB/c-nu mice. The correlations between clinicopathological information and tumor formation rate were analyzed, and the pathological morphology and specific protein expression of PDX model and primary tumor were compared.Results:Thirty-three PDX models were successfully established from 63 cases of liver malignant tumors. The overall tumor formation rate was 52.4% (33/63), including 46.3% (25/54) of primary liver cancer and 88.9% (8/9) of liver metastasis. The main factors affecting the tumor formation rate were tumor pathological type, distant metastasis and TNM stage (all P<0.05). The pathological morphology and specific protein expression of PDX model and primary tumor were similar. Conclusion:The PDX model of liver malignant tumor was successfully constructed, and the tumor formation rate was high, and can maintain the biological characteristics of the primary tumor.

Objective:To explore the status and influencing factors of positive feelings of caregivers of patients with enterostomy, so as to provide a reference for targeted interventions.Methods:From May to October 2021, convenience sampling was used to select 130 caregivers of patients with enterostomy who received follow-up visits in the Stoma Clinic of the First Affiliated Hospital of Xi'an Jiaotong University as the research subject. The survey was carried out using the General Information Questionnaire, the Positive Aspects of Caregiving (PAC) , and the Care Preparedness Scale (CPS) . A total of 130 questionnaires were distributed, and 127 valid questionnaires were recovered, with a valid recovery rate of 97.69%.Results:Among 127 caregivers of patients with enterostomy, the total score of PAC was (32.69±4.99) , and the self-affirmation dimension score was (18.39±2.84) , and the life outlook dimension score was (14.36±2.53) , and the total score of CPS was (17.76±4.36) . Multiple linear regression analysis showed that caregiver gender, education level, work status, and readiness were the influencing factors of positive feelings of caregivers of patients with enterostomy ( P<0.05) , which explained 43.7% of the total variance. Conclusions:The positive perception of caregivers of patients with enterostomy is at an upper-middle level. Nurses should formulate targeted humanistic care strategies according to the influencing factors, increase the positive feelings of caregivers, help patients adapt to the stoma as soon as possible, and then improve the quality of life of patients.

Objectives? To explore the effects of applying growth mentor program in the training of new nurses. Methods? By convenient sampling, the newly recruited nurses who signed official employment contract with the First Affiliated Hospital of Xi'an Jiaotong University were selected as subject. A total of 756 nurses who enrolled from 2008 to 2012 were put into the control group and 812 nurses enrolled from 2013 to 2017 were in the observation group. The control group received routine training while the observation group received the training of the growth mentor program. The two groups was compared in the resignation rate, annual assessment scores, and patients' satisfaction. Results? The differences in resignation rate between the observation group (0.37%) and the control group (1.06%) were statistical significant (P＜0.01). The annual assessment scores of the observation group (88.63±2.17) and patients' satisfaction (96.78±1.76) were all higher than the control group with statistical significance (P＜ 0.01). Conclusions? The establishment and implementation of the new nurses' growth mentor program can significantly reduce the nurses' resignation rate, improve the nurses' professional skills and patients' satisfaction, therefore the program should be widely applied in new nurses' training in hospitals.

Santalene and santalol are the main components of valuable perfume sandalwood essential oil, and have good antibacterial, anti-oxidation and anti-tumor activities. Commercial sandalwood essential oil is mainly extracted from sandalwood tree that grows slowly and is difficult to cultivate. In addition, the extraction recovery of sandalwood essential oil from sandalwood tree is too low to meet the market demand. These factors make sandalwood essential oil expensive. An option is to use genetic engineering and molecular biological methods to heterologously express related synthase of santalene and santalol in microbial host. In this paper, the biosynthesis progress of santalene and santalol synthase, as well as the optimization of mevalonate metabolic pathways in the hosts are summarized. Furthermore, the strategies of applying protein engineering technology to carry out orthomutation of santalene synthase were also discussed, to provide reference for the optimal biosynthesis of santalene and santalol.
