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.

The accumulation and spread of prion-like proteins is a key feature of neurodegenerative diseases (NDs) such as Alzheimer's disease, Parkinson's disease, or Amyotrophic Lateral Sclerosis. In a process known as 'seeding', prion-like proteins such as amyloid beta, microtubule-associated protein tau, α-synuclein, silence superoxide dismutase 1, or transactive response DNA-binding protein 43 kDa, propagate their misfolded conformations by transforming their respective soluble monomers into fibrils. Cellular and molecular evidence of prion-like propagation in NDs, the clinical relevance of their 'seeding' capacities, and their levels of contribution towards disease progression have been intensively studied over recent years. This review unpacks the cyclic prion-like propagation in cells including factors of aggregate internalization, endo-lysosomal leaking, aggregate degradation, and secretion. Debates on the importance of the role of prion-like protein aggregates in NDs, whether causal or consequent, are also discussed. Applications lead to a greater understanding of ND pathogenesis and increased potential for therapeutic strategies.

Objective:To explore the causes and therapeutic effects of pelvic pain caused by rectal fistula or bladder fistula after comprehensive treatment of cervical cancer and rectal cancer (radiotherapy, surgery, chemotherapy, and other treatments).Methods:A retrospective analysis was conducted on the clinical and pathological data of patients with pelvic tumors admitted to the First People's Hospital of Yinchuan City, Ningxia and the Affiliated Cancer Hospital of Zhengzhou University from June 2016 to June 2022. The causes of persistent pelvic pain in patients after comprehensive treatment was investigated, and the corresponding therapeutic effects after clinical treatment was observed.Results:Thirty-two tumor patients experienced persistent pain after comprehensive treatment, including 22 cases of cervical cancer and 10 cases of rectal cancer. The preoperative pain of the entire group of patients was evaluated using the digital grading method, with a pain score of (7.88±1.31) points. Among the 32 patients, there were 16 cases of rectovaginal fistula or ileovaginal fistula, 9 cases of vesicovaginal fistula, 5 cases of rectoperineal fistula, and 2 cases of vesicovaginorectal fistula. Thirty-two patients were initially treated with medication to relieve pain, and according to the ruptured organs, a fistula was made to the corresponding proximal intestinal canal and renal pelvis to intercept the intestinal contents and urine. However, the pain did not significantly be improved. The pain score of treatment with the above methods for one week was (8.13±1.13) points, and there was no statistically significant difference compared to preoperative treatment ( P=0.417). In the later stage, based on a comprehensive evaluation of whether the tumor had recurred, the value of organ preservation, the benefits of surgery, the balance between survival time and improving quality of life, pathological organ resection or repair was performed. The surgical methods included repair of leaks, local debridement combined with irrigation of proximal intestinal fluid, distal closure of the sigmoid colon combined with proximal ostomy, posterior pelvic organ resection, anterior pelvic organ resection, and total pelvic organ resection. One week after surgery, the patients' pain completely relieved or disappeared, with the pain score of (1.72±1.37) points, which was significantly divergent from the preoperative and initial surgical treatments ( P＜0.001). Conclusions:Palliative pyelostomy and proximal enterostomy cannot effectively alleviate persistent pelvic floor pain. The fundamental way to alleviate pain is complete blocking of the inflammatory erosion of the intestinal fluid and urine.

Methods: A cluster sampling method was used to select 3 126 freshmen from six universities of Hefei City and Wuhu City in Anhui Province in October 2022, who were investigated with Positive Psychological Capital Questionnaire (PPQ), Freshmen s Role Adaptability Scale, Connor Davidson Resilience Scale (CD-RISC) and Life Satisfaction Scale. Independent sample t-test and oneway ANOVA were used to compare the scores (caverage score of items) of various variables of college freshmen with different demographic characteristics. Pearson correlation analysis and multiple linear regression analysis were conducted to analyze the correlation. Results: There were statistically significant differences in scores of psychological capital, resilience, life satisfaction and role adaptation among college freshmen of different origin (large and mediumsized cities: ３.６３± ０.５４，３.７３±０.６４，３.４７±０.８０，３.１４±０.６５；county level city or county seat:３.５７±０.５２，３.６１±０.６３，３.３５±０.７５，３.０９±０.６３；villages and towns:３.５０±０.５０，３.５４±０.５８，３.２３±０.７５，３.０６±０.６０), whether in class committee (yes:３.６３±０.５２，３.６９±０.６０，３.４０± ０.７６ ，３.１８±０.５９； no:３.４３±０.５０，３.４８±０.６４，３.２５±０.７７，２.９３±０.６５), father s education level (junior high school or below:３.５２± ０.５１ ，３.５７±０.６１，３.２７±０.７５，３.０７±０.６１； senior high school or technical secondary school:３.６２±０.５３，３.６８±０.６３，３.４４±０.７８，３.１２±０.６３；junior college or above:３.６８±０.５６，３.７８±０.６４，３.５７±０.８０，３.１９±０.６８)，mother s education level(junior high school or below:３.５３±０.５１，３.５８±０.６１，３.２８±０.７５，３.０６±０.６０；senior high school or technical secondary school:３.６３±０.５５，３.７０±０.６３，３.４８±０.７８，３.１５±０.６６；junior college or above:３.７２±０.５４，３.８６±０.６５，３.６２±０.８３，３.２７±０.７０) ( F / t =11.89,21.89,23.02,3.83；10.08，9.20， 5.20 ，10.63；19.34，20.76，29.52，6.44；22.51，26.79，30.94，13.92， P <0.05). The differences of scores in resilience and role adaptation of different genders (boys:3.66±0.64, 3.12±0.65; girls:3.56±0.59, 3.05±0.58) and in life satisfaction whether being an only child (yes:3.40±0.79; no:3.33±0.76) among college freshmen were statistically significant ( t =4.51, 2.75, 2.35, P <0.05). Pearson correlation analysis showed that psychological capital, resilience and life satisfaction of college freshmen were positively correlated with role adaptation ( r =0.49, 0.49, 0.36), while psychological capital, resilience and role adaptation were positively correlated ( r =0.60, 0.59) and Psychological capital was positively correlated with resistance ( r =0.81)( P <0.01). The results of multiple linear regression analysis showed that gender, whether in class committee, psychological capital, resilience and life satisfaction were positively associated with role adaptation among college freshmen ( R 2=0.28, β =0.04, 0.10, 0.23, 0.26, 0.07， P <0.05). Conclusions Role adaptation of college freshmen is related with psychological capital, resilience and life satisfaction. Schools should strengthen mental health education to promote smooth role transition for college freshmen.

ObjectiveTo investigate the prevalence of overweight， obesity and fatty liver disease （FLD） in adult residents in a suburban area of Shanghai， and to explore the relationship between these conditions and eating out of home （EOH）. MethodsAdult residents from Zhongshan Street， Songjiang， Shanghai， were invited to report their frequency of EOH and undergo a physical examination using B-ultrasonography from May to September 2017. Binary logistic regression analyses were conducted to examine the relationship between EOH and conditions of overweight， obesity， and FLD. ResultsAmong the final sample size of 6 608 participants， the prevalence rates of overweight， obesity， and FLD were 41.65%， 14.71% and 38.29%， respectively. After adjusting for potential confounders， logistic analyses revealed that participants with an EOH frequency > once/week had a 1.44-fold higher prevalence of obesity （P=0.006）， a 1.35-fold higher prevalence of overweight/obesity （P=0.005）， and a 1.36-fold higher prevalence of FLD （P=0.008）. ConclusionThe prevalence of overweight， obesity， and FLD is relatively high in Songjiang， Shanghai. EOH may be a risk factor for these diseases， and residents are recommended to reduce the frequency of EOH.

Objective:To explore the obstacle factors and promoting factors of exercise guidance and implementation after breast cancer surgery, so as to provide reference and basis for the formulation of exercise program after breast cancer patients.Methods:Using the objective sampling method, a total of 10 medical staff and 10 patients with breast cancer after operation from the breast surgery department of the Seven People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine hospital in Shanghai were selected as research objects from July to September 2022. A semi-structured interview was conducted. The interview outline was developed based on the knowledge transformation framework, and the results were analyzed by the content analysis method.Results:The study extracted three levels of influencing factors. The system level included caregiver workload, educational materials, norms and responsibilities and trust in evidence-based evidence. The practitioner level included the level of exercise knowledge, the concern about patient compliance and the emphasis on exercise. The patient level included sports knowledge level, personality and interest, venous line, adverse reaction of treatment, psychological state, weather environment, attention to health and concern of family members.Conclusions:The medical staff need to consider the postoperative exercise guidance for breast cancer patients from the department, themselves and patients, and should fully consider the patients' conditions and subjective experience to improve the patients' exercise compliance.

Objective:To explore the clinical characteristics, treatment and prognosis of primary cardiac tumors in infants and children.Methods:The clinical information for 21 patients with primary cardiac tumor in the Department of Pediatric Cardiology, Beijing Anzhen Hospital Affiliated to Capital Medical University from May 2010 to August 2018 were analyzed retrospectively.Their median age was 7 months (gestational age 26 weeks-15 years old, and 6 cases were found in fetal phase) and 10 cases of them were male, 11 cases were girl.The clinical features, treatment methods and prognosis were summarized.Results:Among the 21 patients, 8 cases had an atypical heart murmur, 2 cases with chest tightness and chest pain, 2 cases with congestive heart failure, 1 case with dizziness and amaurosis, 1 case with cerebral artery embolism, 1 case with higher inflammatory index, and 9 cases were asymptomatic.Totally, 13 cases underwent surgical resection.All of them were confirmed as benign tumors, including 4 cases of rhabdomyoma, 3 cases of myxoma, 3 cases of fibroma and 2 cases of inflammatory myofibroblastic tumor (IMT) and 1 case of teratomas.There was no death during perioperative period.Follow-ups were performed from 3 months to 7 years, and 3 cases had recu-rrence (2 cases with myxomas and 1 cases with IMT). There were 8 cases without treatment, of which 7 cases were clinically diagnosed as transverse leiomyoma.During the follow-up, 3 cases disappeared, 1 case became small, 2 cases had no obvious change, and 1 case was lost to follow-up.One case was considered to be malignant tumor, and died within half a year.Conclusions:Primary cardiac tumors in children are mostly benign, especially transverse leiomyoma, and their clinical manifestations are diverse.Pathological examination is the golden standard for diagnosis.Surgical treatment is a radical method for most cardiac tumors, some benign tumors can be treated with drug adjuvant therapy, while the prognosis is poor for malignant cardiac tumor patients.

Purpose: Long non-coding RNA (lncRNA) is identified as an important regulator involved in oral squamous cell carcinoma (OSCC) tumorigenesis. This study aimed to investigate the functional role and underlying mechanism of LINC00662 in OSCC. Materials and Methods: The expression levels of LINC00662, miR-144-3p, and enhancer of zeste homolog 2 (EZH2) mRNA were quantified with quantitative real-time polymerase chain reaction in OSCC tissues and cell lines. Western blot analysis was used to assay the expression levels of E-cadherin, Vimentin, and EZH2. Cell proliferation, migration, and invasion were monitored by cell counting kit-8 and Transwell assays. Dual-luciferase reporter and RNA immunoprecipitation assays were employed to verify the regulatory relationship between LINC00662 and miR-144-3p. Results: The expression of LINC00662, positively associated with the increased TNM stage and lymph node metastasis of the patients, was up-regulated in OSCC tissues and cells. The overexpression of LINC00662 facilitated the proliferation, migration, and invasion of OSCC cells. MiR-144-3p could bind to LINC00662, and the promoting effect of LINC00662 overexpression was counteracted by miR-144-3p mimic. Moreover, EZH2 expression was negatively regulated by miR-144-3p and positively regulated by LINC00662. The silencing of EZH2 attenuated the promoting effects of overexpression of LINC00662 on cell proliferation, migration, invasion, and epithelial-mesenchymal transition. Conclusion LINC00662, as an oncogenic lncRNA of OSCC, accelerates OSCC progression by repressing miR-144-3p expression and increasing EZH2 expression.
