Temporomandibular joint (TMJ) disc displacement is one of the most significant subtypes of temporomandibular joint disorders, but its etiology and mechanism are poorly understood. In this study, we elucidated the mechanisms by which destruction of inflamed collagen fibrils induces alterations in the mechanical properties and positioning of the TMJ disc. By constructing a rat model of TMJ arthritis, we observed anteriorly dislocated TMJ discs with aggravated deformity in vivo from five weeks to six months after a local injection of Freund's complete adjuvant. By mimicking inflammatory conditions with interleukin-1 beta in vitro, we observed enhanced expression of collagen-synthesis markers in primary TMJ disc cells cultured in a conventional two-dimensional environment. In contrast, three-dimensional (3D)-cultivated disc cell sheets demonstrated the disordered assembly of inflamed collagen fibrils, inappropriate arrangement, and decreased Young's modulus. Mechanistically, inflammation-related activation of the nuclear factor kappa-B (NF-κB) pathway occurs during the progression of TMJ arthritis. NF-κB inhibition reduced the collagen fibril destruction in the inflamed disc cell sheets in vitro, and early NF-κB blockade alleviated collagen degeneration and dislocation of the TMJ discs in vivo. Therefore, the NF-κB pathway participates in the collagen remodeling in inflamed TMJ discs, offering a potential therapeutic target for disc displacement.

Objective To identify the multi-dimensional needs of symptom management for oral cancer patients based on the journey map,and provide references for optimizing the symptom management of oral cancer patients.Methods From September 2023 to March 2024,the purposive sampling was used to select 15 perioperative oral cancer patients from a tertiary A general hospital in Zhengzhou for semi-structured interviews.The content analysis method was used to analyze the data and create a patient journey map.Results According to the time axis of diagnosis and treatment,the symptom management of patients with oral cancer was subdivided into 22 themes including identifying abnormal symptoms,clarifying diagnosis,anxiety,fear and uncertainty,guilt,high-risk behavioral inertia solidification,diagnostic trust crisis and so on from 3 dimensions of task,emotion,and pain point,and a journey map was formed.Conclusion The journey of symptom management for patients with oral cancer is long and complex,and the needs of patients'physiological and psychological symptom management are dynamically changing.In the future,the digital intelligence of big data technology can be combined to achieve whole-process,personalized and precise symptom management to improve the quality of life of oral cancer patients.

BACKGROUND:At present,domestic and foreign studies mainly focus on the comparison of different operation methods for intertrochanteric fracture of femur and the risk of failure in proximal femoral nail antirotation operation.There are few studies on the prognosis of hip function of affected limb after proximal femoral nail antirotation.OBJECTIVE:To analyze the influencing factors of poor hip function recovery in elderly patients with intertrochanteric fracture after proximal femoral nail antirotation surgery,and to construct a score system for predicting hip function after surgery and explore its value.METHODS:A total of 150 patients with intertrochanteric fracture of femur who received proximal femoral nail antirotation surgery in the Affiliated Hospital of Xuzhou Medical University from June 2021 to June 2023 were selected and divided into groups according to the Harris hip function score during postoperative follow-up.A score ≥80 was considered as the good group,and a score＜80 was considered as the poor group.Univariate and binary regression analyses were used to explore the risk factors leading to postoperative hip dysfunction.A score scale was established according to the risk factors.The value of this scoring system in predicting hip function after proximal femoral nail antirotation was investigated by using receiver operating characteristic curve.RESULTS AND CONCLUSION:(1)Among the 150 patients,according to the Harris score standard of the affected hip joint at 1 year follow-up,there were 52 cases in the group with poor functional recovery and 98 cases in the group with excellent functional recovery,with an unsatisfactory rate of 34.7％.(2)The results of univariate comparison between the two groups showed that there were significant differences in age,bone mineral density,number of preoperative underlying complications,type of lateral wall,position of spiral blade,quality of reduction and time of first exercise after surgery between the poor group and the good group(P＜0.05).(3)The results of binary Logistic regression analysis showed:Age ≥75 years old(OR=2.834),osteoporosis(OR=3.002),number of preoperative basic complications＞2(OR=4.024),lateral wall rupture(OR=2.999),position difference of spiral blade(OR=4.025),and time to exercise for the first time after surgery＞4 weeks(OR=3.153)were independent risk factors for hip dysfunction after proximal femoral nail antirotation for the intertrochanteric fractures(P＜0.05);poor reduction quality(OR=1.026)was not an independent risk factor(P＞0.05).(4)Based on the results of binary regression analysis,a score system for predicting good hip function after surgery was established.Receiver operating characteristic curve analysis showed that the threshold for predicting poor hip function after surgery was 4.5 points;the area under the curve was 0.797;the sensitivity was 83.7％and the specificity was 65.4％.(5)These results suggested that age ≥75 years old,osteoporosis,number of preoperative basic comorbidities＞2,lateral wall rupture,poor position of spiral blade,and first time out of bed exercise＞4 weeks after intertrochanteric fracture were risk factors for hip dysfunction after proximal femoral nail antirotation.The establishment of a score prediction system can provide reference value for early clinical identification of high-risk patients with postoperative hip dysfunction,and is conducive to guiding early clinical intervention,adopting more personalized treatment and rehabilitation programs,and promoting the recovery of hip function in patients after surgery.

Objective:To investigate the application effect of health education based on self-determination theory combined with mouth-opening training in patients with multiple jaw fractures so as to improve patients' compliance with postoperative rehabilitation.Methods:The randomized controlled trial methods were adopted. A total of 350 patients with multiple jaw fractures who were admitted to the Department of Oral and Maxillofacial Surgery at the First Affiliated Hospital of Zhengzhou University from January 2022 to July 2023 were selected by convenience sampling method. They were divided into the study group and the control group using the random number table method, 175 cases in each group. The control group received routine perioperative nursing and mouth-opening training. On this basis, the study group received health education based on self-determination theory combined with mouth-opening training. The postoperative Visual Analogue Score (VAS), fear of occlusion score, compliance with rehabilitation training, restriction of mouth opening, Self-rating Anxiety Scale (SAS) score, Self-rating Depression Scale (SDS) score, and satisfaction degree were compared between the two groups.Results:Finally, 342 patients completed the study. Among 172 patients in the study group, there were 80 males and 92 females, with an age of (38.73 ± 9.15) years. Among 170 patients in the control group, there were 82 males and 88 females, with an age of (40.22 ± 10.06) years. The VAS scores of the study group on postoperative days 1, 3, and 7 were (4.92 ± 0.56), (3.68 ± 0.52), and (2.28 ± 0.44), respectively, all lower than those of the control group (5.10 ± 0.60), (4.03 ± 0.55), and (2.66 ± 0.53), and the differences were statistically significant ( t=2.87, 6.05, 7.22, all P<0.05). Fear of occlusion scores of the study group on postoperative days 1, 3 and 7 were (3.88 ± 0.52), (2.67 ± 0.65) and (1.45 ± 0.32), respectively, all lower than those of the control group (4.05 ± 0.39), (3.12 ± 0.73) and (1.68 ± 0.35), and the differences were statistically significant ( t=3.42, 6.02, 6.34, all P<0.05). The total compliance rate of rehabilitation training in the research group was 95.35% (164/172), which was higher than the control group ′s 84.12% (143/170), and the difference was statistically significant ( χ2=11.74, P<0.05). After intervention, SAS score and SDS score of the study group were (36.18 ± 7.15) and (33.08 ± 8.21), respectively, witch were lower than those of the control group (38.34 ± 6.63) and (35.20 ± 7.39), and the differences were statistically significant ( t=2.90, 2.51, both P<0.05). Total satisfaction score of the study group (83.50 ± 12.68) was higher than that of the control group (79.52 ± 14.92), the difference was statistically significant( t=2.66, P<0.05). Conclusions:Health education based on self-determination theory combined with mouth-opening training can help alleviate postoperative pain and fear of occlusion in patients with multiple jaw fractures, improve their compliance with rehabilitation training as well as rehabilitation effect.

Objective:To explore the effectiveness of teach-back method-based health education in patients with oral fungal infections.Methods:Convenience sampling was used to select patients with oral fungal infections who attended the Dental Clinic of the First Affiliated Hospital of Zhengzhou University from June to December 2023 for the study. The patients were divided into control group and observation group according to the randomized numerical table method.

After the intervention, the Chinese version of the Oral Health Impact Profile-49 (OHIP-49) of observation group was lower than that of control group, and the difference was statistically significant ( P<0.05) . Conclusions:The teach-back method-based health education improves adherence, enhances self-management, and promotes oral health in patients with oral fungal infections.

Objective:To systematically synthesize the real experiences of cancer patients undergoing prehabilitation and provide a reference for the development of targeted prehabilitation programs.Methods:A systematic search was conducted in China National Knowledge Infrastructure, Wanfang Data, VIP, China Biology Medicine disc, Web of Science, PubMed, Embase, CINAHL, and Cochrane Library databases for qualitative studies on the prehabilitation experiences of cancer patients. The quality of the included studies was appraised, and the findings were integrated using a Meta-aggregative approach. The search covered publications up to June 30, 2024.Results:A total of 17 studies were included, yielding 76 themes. These were synthesized into 12 categories and further integrated into four integration results: heavy physical and psychological burden with low adherence to programs; positive cognition supported by multiple factors leads to high adherence under appropriate interventions; unmet practical needs require urgent attention; physical and psychological benefits are sustained and influential.Conclusions:Multiple factors affect patients' adherence to prehabilitation, and unmet needs are common. Future research should aim to identify barriers and meet patients' needs.
