Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Purpose To observe the short-term efficacy of CalliSpheres? drug-eluting beads for embolization in the treatment of non-small lung cancer compared with bronchial artery chemoembolization and systemic vein chemotherapy.Materials and Methods A retrospective analysis was performed on 78 patients with pathologically confirmed non-small cell lung cancer from the First Affiliated Hospital of Dali University from March 2016 to September 2018.The patients were assigned to three groups(n=26 each):an observation group receiving CalliSpheres? drug-eluting bead embolization,a control group receiving bronchial arterial chemoembolization,and a conventional group receiving systemic intravenous chemotherapy.In both the observation and control groups,after the tumor-feeding arteries were identified by bronchial arteriography,a coaxial microcatheter was superselectively advanced into these arteries.Chemotherapeutic agents were then infused separately through each individual feeding artery.The observation group underwent embolization using drug-eluting microspheres,whereas the control group underwent embolization with blank microspheres.The conventional group was treated with intravenous chemotherapy.The objective response rates at 2 months post-procedure were compared among the three groups.Results The objective response rates at 2 months post-procedure were as follows:observation group,84.62%;control group,57.69%;conventional group,26.92%.The observation group showed a significantly superior objective response rate relative to the control group and the conventional group(χ2=4.591,17.541,P<0.05).Additionally,the objective response rate in the control group was significantly higher than that in the conventional group(χ2=5.042,P=0.025).Conclusion For non-small cell lung cancer,CalliSpheres? drug-eluting bead embolization provides significantly better short-term clinical efficacy than both bronchial arterial chemoembolization and systemic intravenous chemotherapy.Bronchial arterial chemoembolization itself is more effective than systemic intravenous chemotherapy.

Objective To investigate the protective effect of berberine (BBR) against ionizing radiation injury in rats and its mechanism of action. Methods Sprague-Dawley rats were divided into seven groups: normal control group, 1-Gy radiation group, 1-Gy radiation plus low-dose BBR (50 mg/kg) group, 1-Gy radiation plus high-dose BBR (150 mg/kg) group, 3-Gy radiation group, 3-Gy radiation plus low-dose BBR (50 mg/kg) group, and 3-Gy radiation plus high-dose BBR (150 mg/kg) group. All the groups except the normal control group were exposed to external irradiation with a medical electron linear accelerator, followed by BBR administration by gavage for consecutive ten days. The serum levels of superoxide dismutase (SOD), reduced glutathione (GSH), and malondialdehyde (MDA) were measured by using the micromethod. The pathological changes of the bone marrow and small intestine were observed with HE staining. Results Compared with the normal control group, the radiation groups showed significantly increased MDA levels (P < 0.05), significantly decreased SOD and GSH levels (P < 0.05), and more severe pathological damage of the bone marrow and small intestine. Compared with the radiation groups, the BBR groups showed significantly decreased MDA levels (P < 0.05), significantly increased SOD and GSH levels (P < 0.05), and reduced pathological damage to the bone marrow and small intestine, which were more marked in the high-dose BBR group. Conclusion BBR has a certain protective effect against radiation injury in rats, which may be through increasing the activity of antioxidant substances, enhancing free radical clearance, and thereby alleviating free radicals-caused oxidative damage.

Objective: To explore the efficacy and safety of transcatheter pulmonary valve perforation in the treatment of neonatal pulmonary atresia with intact ventricular septum (PA-IVS). Methods: The clinical data on surgical treatment and follow-up in 16 patients with PA-IVS who underwent transcatheter pulmonary valve perforation in Women and Children's Hospital, Qingdao University from October 2018 to October 2021 were analyzed retrospectively. The right ventricular systolic pressure and percutaneous oxygen saturation (SpO₂) were compared before and after operation. In addition, the SpO₂ and echocardiographic data at preoperative and the last follow-up were compared. Comparisons between groups were performed using paired-samples t test. Results: Among the 16 patients (10 males and 6 females) with the age at operation of 19 (14, 26) days, 12 cases underwent transcatheter pulmonary valve perforation successfully, 2 cases were transferred to surgery department for open-heart pulmonary valvulotomy, and the remaining 2 cases were transmitted to surgery department for transthoracic pulmonary valve perforation. The age at operation of the 12 patients who underwent transcatheter pulmonary valve perforation was 18 (14, 27) days, and the weight was (3.6±0.4) kg. The immediate postoperative right ventricular systolic pressure decreased significantly ((57±16) vs. (95±19) mmHg (1 mmHg=0.133 kPa), t=7.49, P<0.001), and the postoperative SpO₂ was improved effectively (0.90±0.48 vs.0.75±0.09, t=-5.61, P<0.001). The follow-up time was 22 (7, 33) months for 12 patients who underwent transcatheter pulmonary valve perforation successfully. At the last follow-up, the ratio of right to left ventricular transverse diameter was significantly higher than that before operative (0.55±0.05 vs. 0.45±0.05, t=-3.27,P=0.007). Furthermore, the Z-scores of pulmonary valvular diameter (-0.78±0.23 vs. -1.73±0.56, t=-8.52, P<0.001) and the tricuspid valvular diameter (-0.52±0.12 vs. -1.46±0.38, t=-10.40, P<0.001) were all significantly higher than preoperative data. At last, all the patients achieved biventricular circulation without death or major complications. Conclusion: Transcatheter pulmonary valve perforation is a safe and effective therapy for neonatal PA-IVS, and its curative effect has been confirmed by the medium follow-up data.

From birth to adulthood, we often align our behaviors, attitudes, and opinions with a majority, a phenomenon known as social conformity. A seminal framework has proposed that conformity behaviors are mainly driven by three fundamental motives: a desire to gain more information to be accurate, to obtain social approval from others, and to maintain a favorable self-concept. Despite extensive interest in neuroimaging investigation of social conformity, the relationship between brain systems and these fundamental motivations has yet to be established. Here, we reviewed brain imaging findings of social conformity with a componential framework, aiming to reveal the neuropsychological substrates underlying different conformity motivations. First, information-seeking engages the evaluation of social information, information integration, and modification of task-related activity, corresponding to brain networks implicated in reward, cognitive control, and tasks at hand. Second, social acceptance involves the anticipation of social acceptance or rejection and mental state attribution, mediated by networks of reward, punishment, and mentalizing. Third, self-enhancement entails the excessive representation of positive self-related information and suppression of negative self-related information, ingroup favoritism and/or outgroup derogation, and elaborated mentalizing processes to the ingroup, supported by brain systems of reward, punishment, and mentalizing. Therefore, recent brain imaging studies have provided important insights into the fundamental motivations of social conformity in terms of component processes and brain mechanisms.

ObjectiveTo explore the effect of hip neuromuscular training on reducing the risk of anterior cruciate ligament (ACL) injury in female soccer players. MethodsFrom March to May, 2022, 39 female soccer players from Xi'an Physical Education University were randomly divided into control group (n = 19) and experimental group (n = 20). On the basis of daily training, the control group received sham intervention, and the experimental group received hip neuromuscular training, for six weeks. Before and after training, they were measured dynamic knee valgus (DKV) angle and assessed with Landing Error Score System (LESS); while they were also measured the maximal voluntary isometric contraction (MVIC) and root mean square (RMS) of electromyography as single leg landing of gluteus medius and gluteus maximus. ResultsAll the indexes varied little after training in the control group (|t| < 1.178, P > 0.05), while the indexes improved in the experimental group (|t| > 2.288, P < 0.05), except sagittal score of LESS; and all the indexes improved more in the experimental group than in the control group (|t| > 2.609, P < 0.05), except sagittal score of LESS and MVIC of gluteus maximus. ConclusionHip neuromuscular training can reduce the risk of ACL injury in female soccer players.
