Objective:To explore the application effects of the goal-oriented teaching method based on mind mapping in the teaching of stomatology practical courses.Methods:From September 2022 to September 2023, 52 fourth-year students of clinical stomatology at Harbin Medical University were divided into test group and control group for practical teaching, with 26 cases in each group. The test group received goal-oriented teaching based on mind mapping, while the control group received traditional teaching, for 20 class hours in both groups. The two groups were compared in terms of general data, theoretical and practical assessment scores, the score of the self-rating scale of self-directed learning (SRSSDL) and the score of critical thinking disposition inventory-Chinese version (CTDI-CV) before and after training, and student satisfaction with teaching activities. SPSS 25.0 software was used to perform the t-test or χ2 test. Results:After completing the practical training courses, the test group showed significantly higher scores than the control group in multiple-choice questions [(16.85±1.39) vs. (15.33±2.21)], fill-in-the-blank questions [(17.21±1.98) vs. (16.01±2.02)], short answer questions [(17.47±2.27) vs. (15.23±2.45)], case analysis [(34.36±2.79) vs. (32.57±3.02)], and practical assessment [(84.69±4.73) vs. (80.57±4.21)] (all P<0.05). The SRSSDL score and CTDI-CV score were improved in both groups, and were significantly higher in the test group [(215.29±10.42) and (357.49±17.80)] than in the control group [(200.23±11.42) and (342.23±17.26)] (both P<0.05). The students of the test group were significantly more satisfied with teaching activities than those of the control group ( P<0.05). Conclusions:Compared with the traditional teaching method, the goal-oriented teaching method based on mind mapping is more effective in stomatology practical teaching, which can improve students' self-directed learning ability and critical thinking ability, promote their mastery of theoretical knowledge, enhance their clinical practice ability, and increase their satisfaction with teaching activities.

Two researchers independently used corresponding quality evaluation tools to evaluate the methodological quality of the included literature. They extracted and summarized the best evidence for the management of fatigue-related symptom clusters in HIV/AIDS patients.Results:A total of 20 articles were included, including seven clinical decisions, three guidelines, two evidence summaries, one expert consensus, three systematic reviews, and four randomized controlled trials. Thirty-four pieces of evidence were summarized from four aspects: fatigue management, frailty management, sexual dysfunction management, and sleep disorder management.Conclusions:This study summarizes the best evidence for the management of fatigue-related symptom clusters in HIV/AIDS patients. Medical and nursing staff must select and apply the evidence in a targeted manner based on clinical situations.

Objective To evaluate the role of preoperative serological indexes in predicting long-term survival and tumor recurrence of hepatocellular carcinoma (HCC) patients after liver transplantation, aiming to explore its significance in expanding the Milan criteria. Methods Clinical data of 669 recipients undergoing liver transplantation for HCC were retrospectively analyzed. The optimal cut-off value was calculated by the receiver operating characteristic (ROC) curve. The risk factors affecting the overall survival and recurrence-free survival rates of HCC patients after liver transplantation were identified by univariate and multivariate regression analyses. The correlation between preoperative serum liver enzymes and pathological characteristics in HCC patients was analyzed. The predictive values of alpha-fetoprotein (AFP) combined with γ -glutamyl transferase (GGT) and different liver transplant criteria for the survival and recurrence of HCC patients after liver transplantation were compared. Results Exceeded Milan criteria, total tumor diameter (TTD) > 8 cm, AFP > 200 ng/mL and GGT > 84 U/L were the independent risk factors for the overall survival and recurrence-free survival rates of HCC patients after liver transplantation (all P < 0.05). Correlation analysis showed that preoperative serum GGT level was correlated with TTD, number of tumor, venous invasion, microsatellite lesions, capsular invasion, tumor, node, metastasis (TNM) stage, Child-Pugh score and exceeded Milan criteria (all P < 0.05). Milan-AFP-GGT-TTD (M-AGT) criteria were proposed by combining Milan criteria, TTD with serum liver enzyme indexes (AFP and GGT). The 5-year overall survival and recurrence-free survival rates of HCC recipients who met the M-AGT criteria (111 cases of exceeded Milan criteria) were significantly higher than those who met Hangzhou criteria (both P < 0.05), whereas had no significant difference from their counterparts who met the University of California at San Francisco (UCSF) criteria (both P > 0.05). Conclusions Preoperative serological indexes of AFP and GGT could effectively predict the long-term survival and tumor recurrence of HCC patients after liver transplantation. Establishing the M-AGT criteria based on serological indexes contributes to expanding the Milan criteria, which is convenient and feasible.

Objective:To explore the distribution of perihip stress in male marathon runners and normal volunteers during the gait cycle using finite element analysis.Methods:In November 2022, the hip joint CT image data of a male marathon runner and a male healthy volunteer was collected. The gait cycle was divided into 7 phases, including the foot to the ground, the early, middle, and late period of one-foot support, the toe push and extension period, and the beginning and end of the swing. A three-dimensional finite element model was constructed based on the gray value of CT and according to the individualized material attribute assigning scheme. The dynamic change of hip joint contact force during the gait cycle was applied to the load, and the biomechanical qualitative analysis of the model was carried out through the equivalent stress results. Based on qualitative analysis, the same 10 nodes on the front, middle, and back of the model acetabulum, the front, and back of the femoral head, and the neck of the femur were extracted as equivalent stress reference points, and the biomechanical quantitative analysis of the model was carried out.Results:During the gait cycle, according to the hip equivalent stress distribution diagram, the contact on the articular surface of the two subjects mainly occurred in the posterior upper part of the acetabulum and the posterior part of the femoral head and gradually moved outward and backward with the joint force during walking. From the point of view of the stress distribution nodes around the hip joint, the stress changes of the nodes in each part of the two subjects showed bimodal characteristics with the load inside the hip joint at each phase. The internal stress value of the hip joint showed a gradual upward trend from the foot to the ground, reached the maximum stress in the middle period of one-foot support, then decreased, and slightly increased in the toe push and extension period. Then, the stress values at the beginning and end of the swing gradually decreased until entering the next gait cycle. The stress values in the posterior acetabulum and posterior femoral head of the marathon runner were smaller than those of the healthy volunteer.Conclusion:The stress around the hip joint was different between marathon runner and healthy volunteer, but the stress distribution and transmission path were the same.

Abstract：Objective To evaluate the basic development status of public health emergencies of infectious diseases in Hainan Province from 2013 to 2022, analyze the distribution and characteristics of these emergencies, as to provide important scientific basis for the study and formulation of economic health development planning policies, for the health security policies and infectious disease prevention and control strategies in Hainan Province. Methods The relevant statistical data of public health emergencies involving infectious diseases reported in Hainan Province from 2013 to 2022 were collected, and the status quo of these emergencies was analyzed by using descriptive data statistical analysis method. The ARIMA model was used to predict the number of public health emergencies reported by infectious diseases in Hainan Province from 2023 to 2025. Results From 2013 to 2022, a total of 482 public health emergencies were reported in Hainan Province, of which 426 were infectious disease public health emergencies, accounting for 88.38%, with a total of 8 876 cases, an incidence rate of 0.61%, and eight deaths, a case fatality rate of 0.09%. The major public health emergencies of infectious diseases were unclassified events and general events, accounting for 69.25% and 29.58%, respectively. The main diseases were novel coronavirus infection, chickenpox and hand, foot and mouth disease, accounting for 45.07%, 15.49% and 11.97%, respectively; in terms of time distribution, the number of reported incidents showed an upward trend over time, with a decline in 2021, and mainly had three peak periods, April, August and December, with a total of 220 cases reported; in terms of regional distribution, the major cities and counties reported were Haikou, Wanning and Wenchang, accounting for 27.46%, 19.25% and 9.86%, respectively; in terms of location distribution, the events mainly occurred in schools, accounting for 42.02% of the total number of incidents. The ARIMA(1, 1, 0) model was used to predict infectious disease public health emergencies, and the results showed that the forecast state would be stable from 2023 to 2025, with no obvious upward trend, that is, the fluctuation range of public health emergencies related to infectious diseases in Hainan Province would be stable in the next three years. Conclusion The number of infectious disease public health emergencies reported in Hainan Province from 2013 to 2022 has increased year by year, with a decline in 2021. Although the forecast shows that public health emergencies such as infectious diseases are relatively stable with no obvious upward trend, the prevention and control of the epidemic should not be taken lightly. Hainan Province should continue to increase the investment in monitoring public health emergencies, improve the information system of public disease prevention and control, and carry out real-time monitoring of public health emergencies of infectious diseases.

Objective:To explore the mediating effects of nursing information ability on transition shock and mental health in intern nursing students.Methods:From November to December 2021, a total of 220 intern nursing students from 4 Grade A hospitals in Zhejiang province were selected as the research objects using the convenient sampling method. General data questionnaire, Nursing Practice Information Competency Assessment Scale, Transition Shock Scale for Undergraduate Nursing Students and General Health Questionnaire were used to investigate intern nursing students. Pearson correlation analysis was used to analyze the relationship between nursing information ability, transition shock and mental health of intern nursing students. AMOS 21.0 was used to establish the structural equation model and verify the mediating effects. In this study 220 questionnaires were sent out and 212 were returned, and the effective recovery rate of the questionnaire was 96.36%.Results:The mental health score of 212 nursing students was (12.78±3.76) , nursing information ability score was (58.73±9.75) , transition shock score was (52.67±8.53) . The results of structural equation model showed that transition shock directly predicted mental health (effect value was 0.417) , and nursing information ability played a mediating role between transition shock and mental health (effect value was 0.381) .Conclusions:Nursing information ability is the mediating variable on transition shock and mental health of intern nursing students. Nursing managers should take active measures to help intern nursing students reduce transition shock and improve nursing information ability, so as to enhance mental health level.

In group S, 0.2% ropivacaine 5 ml was injected into the surface of the right longus colli muscle where the the stellate ganglion was located under ultrasound guidance once a day for 7 consecutive days starting from 1 h before bedtime.While the equal volume of normal saline was given instead in group C. Patients′ Subjective Sleep Quality was assessed using the Pittsburgh Sleep Quality Index Questionnaire before treatment (T 0) and 1-7 days after treatment.The objective sleep quality was evaluated with polysomnography.A bispectral index(BIS)monitor and a cerebral and regional blood oxygen monitoring system were used to monitor the BIS value and regional cerebral oxygen saturation (rSO 2) during sleep, which were recorded once every 30 min, and the 7-day average was calculated.The patients′ daytime advanced cognitive function was assessed for 3 consecutive days after the end of treatment (T 8-10), including the Continuous Attention Test and the Behavioral Test for Performing Defect Syndrome, and the 3-day average value was calculated.Venous blood samples were collected at T 0 and T 8 to measure the plasma noradrenaline, cortisol, and serotonin concentrations by high-performance liquid chromatography. Results:Compared with group C, the individual and total scores of Pittsburgh Sleep Quality Index were significantly decreased, the sleep latency, awakening time and fast wave sleep latency were shortened, the number of awakening was increased, the total sleep time was prolonged, the sleep efficiency and proportion of fast wave sleep were increased, S 1-S 2 ratio in slow-wave sleep was decreased, S 3-S 4 ratio was increased, BIS value was decreased, rSO 2 was increased, each parameter of Continuous Attention Test was decreased and each parameter of Behavioral Test for Performing Defect Syndrome was increased after treatment, and plasma noradrenaline level was decreased at T 8 in group S ( P<0.05). Conclusion:Stellate ganglion block can improve nighttime sleep quality in patients with primary sleep disorders.

Objective: To explore the relationship between selenium and the risk for oral cancer. Methods: We performed a case-control study in 325 cases of newly diagnosed primary oral cancer from the First Affiliated Hospital of Fujian Medical University and 650 controls from the same hospital and community. Unconditional logistic regression and stratification analyses were used to explore the association between selenium and oral cancer. Adjusted OR and corresponding 95%CI were calculated. The analyses on multiple interactions between selenium and smoking or drinking status, and fruit or fish intake frequencies were conducted. Results: The level of serum selenium was 112.42 (80.98-145.06) μg/L in the case group, which was lower than 164.85 (144.44-188.53) μg/L in control group, the difference was statistical significant (P<0.01). There was a negative correlation between serum selenium level and the risk for oral cancer regardless of smoking and drinking status, and fruits and fish intake frequencies (P<0.05). There were multiple interactions between serum selenium level and smoking or drinking status, and fruit and fish intakes. Conclusions The high level of serum selenium is a protective factor for the incidence of oral cancer, and serum selenium has multiple interactions with smoking or drinking status, and fruit and fish intakes. Therefore, reducing tobacco use and alcohol consumption and increasing the intakes of fruit and fish can reduce the risk for oral cancer to some extent.

Objective: To explore the association of TBX5 polymorphisms and environmental exposure index with susceptibility to oral cancer. Methods: A case-control study was conducted to collect 300 oral cancer patients hospitalized in the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Fujian Medical University from September 2010 to December 2016. A total of 445 non-tumor patients were selected as the control group. Questionnaires were used to collect the information of all subjects and 5 ml peripheral blood was collected to detect single nucleotide polymorphisms (SNPs) of the rs10492336 locus of TBX5 gene. According to the environmental exposure index score, subjects were divided into two groups, low risk group (0-2.31) and high risk group (2.32-11.76). To analyze the association of TBX5 gene rs10492336 SNPs, environmental exposure index and oral cancer and its interactions. Results: The age of all subjects in the case group and control group were (56.19±13.10) years and (54.56±12.48) years old. Compared with CC genotype, the OR (95%CI) values of the co-dominant genetic model AC genotype and the dominant genetic model AC+AA genotype were 0.69 (0.49-0.98) and 0.70 (0.51-0.97), respectively. Compared with the low risk group, the OR (95%CI) risk of oral cancer in the high risk group was 3.72 (2.55-5.43). The results of gene-environment interaction analysis showed that compared with the group with CC genotype and high risk of environmental exposure index, the OR (95%CI) value of oral cancer in the group with AC+AA genotype and low risk of environmental exposure index was 0.18(0.10-0.31). Furthermore there was a multiplicative interaction between rs10492336 SNPs and environmental exposure index (β=-0.405, P<0.001). Conclusion This study suggests that the TBX5 gene rs10492336 SNPs and environmental exposure index were associated with oral cancer. And there was a multiplication interaction between rs10492336 SNPs and environmental exposure index.
