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.

Objective:To assess the levels and abnormal rates of trace elements and vitamins among older patients in Beijing Hospital, and to analyze the correlations between these measured indicators.Methods:This study selected 49 older individuals who underwent physical examinations at Beijing Hospital between May 2021 and March 2024.The participants were divided into two age groups: 60-79 years old(23 cases)and 80-100 years old(26 cases). Levels' differences of trace elements and vitamins between the two age groups were analyzed.Pearson correlation analysis was used to investigate the correlations among the tested indicators, and multivariate analysis was conducted using a generalized linear regression model.Results:Among the 49 older individuals, the overall abnormal rate for trace element test results was 8.16%(4 cases), with 2 cases of iron(Fe)deficiency(4.08%)and 2 cases of calcium(Ca)deficiency(4.08%). The overall abnormal rate for vitamin test results was 24.49%(12 cases), which included 5 cases of vitamin B2 deficiency(10.20%), 1 case of vitamin C deficiency(2.04%), and 6 cases of vitamin D deficiency(12.24%). Statistically significant differences were observed between the two age groups in zinc(Zn)and vitamin C levels( t=2.84, 2.83; P=0.007, 0.007). Pearson correlation analysis revealed correlations among 19 pairs of indicators.The top five correlations were between plumbum(Pb)and cadmium(Cd)( r=0.769, P<0.001), Fe and manganese(Mn)( r=0.685, P<0.001), Ca and magnesium(Mg)( r=0.677, P<0.001), vitamin B12 and vitamin C( r=0.455, P=0.001), and vitamin B9 and vitamin D( r=0.422, P=0.003), respectively.The results of the multivariate analysis indicated that, after adjusting for the effects of age group and gender, statistical differences in correlations remained among the remaining trace elements and vitamins, except for those between vitamin B1 and vitamin B12, vitamin B1 and vitamin C, and vitamin A and vitamin D (all P<0.05). Conclusions:The deficiency rates of trace elements and vitamins remain notably high among older patients in our hospital, underscoring the necessity for enhanced nutritional supplementation and regular monitoring of trace element and vitamin levels within this population.Furthermore, a correlation exists between trace elements and vitamins, which offers valuable insights for the diagnosis and treatment of related diseases.

Objective:To discuss the relationship between the systolic blood pressure (SBP) circadian rhythm and blood pressure variability (BPV) and the left ventricular ejection fraction (LVEF) among 178 patients with hypertension.Methods:This article was a retrospective study. Totally 178 patients with hypertension from January 2020 to January 2022 were selected based on incorporated basis. 24-hour dynamic blood pressure monitoring and echocardiography examination were performed. Data such as patients' SBP circadian rhythm, BPV, heart ultrasound heart dynamic maps were collected, and the relationship between SBP circadian rhythm and BPV and their LVEF was explored.Results:Among the 178 patients, the decreased proportion of SBP circadian rhythm>the proportion of existed SBP circadian rhythm>the proportion of inverted SBP circadian rhythm>the proportion of disappearance of SBP circadian rhythm; patients with disappearance of SBP circadian rhythm were the youngest (63.8 ± 14.5) years old, and patients with inverted SBP circadian rhythm were the oldest (71.5 ± 9.4) years old ( P<0.05); the 24-hour systolic blood pressure standard deviation of SBP circadian rhythm was observed in patients with (13.1 ± 2.8) mmHg

Objective To develop an active monitoring model for adverse drug events(ADEs)related to antimicrobial use in children based on the China hospital pharmacovigilance system(CHPS).Methods Trigger items for the active monitoring model were initially drafted through a review of relevant literature,adverse reaction databases,and drug label warnings,and subsequently refined using the Delphi method.A retrospective analysis was performed on pediatric inpatients who received antibiotics at Anning First People's Hospital between January 1 and December 31,2024.The detection rate and positive predictive value(PPV)of the active monitoring model were calculated and compared with spontaneous ADE reports from the same period.Risk factors for ADEs were further analyzed using logistic regression.Results 25 trigger items were established for the active monitoring model.Among 1,784 cases,233 ADEs were identified,yielding a detection rate of 13.06%(233/1,784).The spontaneous reporting rate of adverse events during the same period was 1.85%(33/1,784).The difference between the two was statistically significant(P<0.001).There were 727 positive trigger events,with 299 cases of ADE detected,resulting in an overall PPV of 41.13%(299/727).Logistic regression revealed that antibiotic use exceeding 3 days(OR=1.454,95%CI:1.012-2.088)was significantly associated with ADE occurrence.Conclusion Compared with conventional spontaneous reporting,the active monitoring model can significantly improve the detection rate of ADEs of pediatric antimicrobial drugs and achieve active and real-time monitoring of drug adverse events.

Objective To construct a rational and efficient bed resource allocation management model to reduce pre-hos-pital waiting times,ensure patient safety,and improve satisfaction.Methods Based on lean management principles,a bed re-source allocation management model was developed and continuously optimized.The study compared bed turnover rates and effi-ciency indices,as well as preoperative waiting times for surgical patients,average length of stay,patient satisfaction,and anxiety incidence before and after the implementation of the lean model to evaluate its effectiveness.Results After implementing the lean bed resource allocation model,the bed efficiency index increased by 14.29％,and bed turnover rates improved by 3.34％.The average preoperative waiting time for surgical patients decreased by 100％,and the average length of stay reduced by 87.71％.Patient satisfaction increased by 2.4％,while anxiety incidence dropped by 28.1％.Conclusion The implementa-tion of a lean bed resource allocation model can enhance hospital bed efficiency,shorten preoperative waiting times for surgical patients,reduce average length of stay,and improve patient satisfaction.

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.

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 influencing factors of role adaptation of college freshmen, so as to provide empirical support for developing adaptive education in college. 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.
