This paper discusses the pathogenesis and treatment strategies of skin cancer based on the theory of "spleen deficiency-sweat pore obstruction-toxin accumulation". It is believed that although the disease is located in the skin and body hair， it is not only the localized disorder but closely related to the imbalance of qi and blood of zang-fu （脏腑） organs. The core of the disease is the synergistic disorder of spleen， sweat pore， and skin and body hair. The disease progression follows a dynamic evolution from spleen deficiency with loss of nourishment， initial closure of sweat pore to binding of dampness and stasis with obstruction of sweat pore， and then to cancer toxin consolidation with damage to sweat pore. Based on this， three principles of building earth， opening sweat pore and attacking toxin are established. The method of fortifying spleen and raising the clear aims to consolidate the root and restore validity， with commonly used prescriptions including modifications of Buzhong Yiqi Decoction （补中益气汤）， Liujunzi Decoction （六君子汤） and Guipi Decoction （归脾汤）. The method of opening sweat pores with acrid-moistening medicinals is suggested when dredging and unblocking the sweat pore， commonly using acrid and warm dispersing medicinals， supplemented with herbs that nourish fluids and moisten dryness. The method of clearing heat and removing toxin is to break cancer toxin directly， and modifications of prescriptions such as Wuwei Xiaodu Beverage （五味消毒饮）， Xiaolei Pills （消瘰丸） and Xihuang Pills （犀黄丸） are commonly used. These approaches provide valuable ideas for the prevention and treatment of skin cancer with traditional Chinese medicine.

OBJECTIVE To provide direction and reference for the adjustment of the discount rate （DR） in China’s pharmacoeconomic guidelines. METHODS Search was conducted on the official websites of the International Society for Pharmacoeconomics and Outcomes Research， health technology assessment agencies in various countries/regions， as well as relevant websites of other upper-middle-income or high-income countries/regions. The recommended DR， adjustment trends， and setting rationales in pharmacoeconomic evaluation guidelines across different countries/regions were then summarized and compared. Based on theoretical derivation and literature analysis， the effects of different DR on the incremental cost-effectiveness ratio （ICER） were examined. RESULTS & CONCLUSIONS Among the 40 included guidelines， the base-case DR ranged from 1.5% to 5%， with 5% being the most common value； the range for sensitivity analysis was 0 to 12%. Thirty-six countries/regions applied the same DR to both costs and health outcomes， while in the Netherlands， Belgium， Poland and Czech Republic， DR for costs was higher than for health outcomes. In recent years， Korea， France and Ireland had lowered their DR in response to economic changes， whereas the Netherlands and Czech Republic had raised their DR for cost. The setting of the DR was primarily based on the public project investment interest rate or referred to recommendations from internationally authoritative institutions and other relevant guidelines. The direction and magnitude of the impact of different DR on the ICER largely depended on the distribution of costs and health outcomes between the intervention and reference measure. The setting and adjustment of DR were closely associated with the economic environment. Based on international experience, the DR in China can be lowered by 0.5% to 1.5%， and localized empirical research can be conducted using internationally common estimation methods.

In response to the clinical needs of cancer treatment and rehabilitation, Professor Lin Hongsheng proposed the Wuzhi Wuyang (five treatments and rehabilitation) concept on the basis of years of clinical experience and the Guben Qingyuan (consolidate the foundation and clear the source) theory. Wuzhi Wuyang emphasizes the importance of treatment and rehabilitation and aims to provide personalized and stage-specific treatment and rehabilitation plans by integrating the advantages of traditional Chinese medicine (TCM) and modern medicine to achieve comprehensive life-cycle management for patients with cancer. The proposal of Wuzhi Wuyang has provided new ideas and methods for the treatment, prevention, and rehabilitation of cancer, along with valuable references for clinical practice and academic research. This article summarizes the connotation of Wuzhi Wuyang and its application in the comprehensive management of cancer prevention and treatment with TCM.

Objective:To identify the risk factors for postoperative sleep disturbance (PSD) in patients undergoing spine surgery.Methods:In this case-control study, patients who underwent spine surgery from December 2023 to June 2024 at Beijing Tiantan Hospital of Capital Medical University, were selected as the subjects of the study. The quality of postoperative sleep was assessed using the Athens Insomnia Scale (AIS). The baseline characteristics and various perioperative indicators of the patients were collected. The patients were divided into PSD group and non-PSD group according to whether they had PSD. The variables with statistically significant differences from the univariate analysis were included in a multivariate logistic regression to identify the risk factors for PSD.Results:The results of the multivariate logistic regression analysis showed that preoperative sleep disturbance (odds ratio [ OR]=2.23, 95% confidence interval [ CI] 1.06-4.72, P=0.036), course of disease > 12 months ( OR=2.20, 95% CI 1.14-4.24, P=0.019) and AIS score > 2 on the night before surgery ( OR=2.06, 95% CI 1.02-4.16, P=0.045) were the independent risk factors for PSD in patients undergoing spine surgery. Conclusions:Preoperative sleep disturbance, course of disease > 12 months and AIS score > 2 on the night before surgery are independent risk factors for PSD in patients undergoing spine surgery.

This position statement explores the intricate relationship between alcohol intake and metabolic dysfunction in the context of the 2023 nomenclature for steatotic liver disease (SLD). Recent and lifetime alcohol use should be accurately assessed in all patients with SLD to facilitate classification of alcohol use in grams of alcohol per week. Alcohol biomarkers (phosphatidylethanol), use of validated questionnaires, and collateral information from friends and relatives could help facilitate differentiation between alcohol-related liver disease per se and liver disease with both metabolic and alcohol-related liver disease. Heavy alcohol use can contribute to cardiometabolic risk factors such as high blood pressure, hypertriglyceridemia, and hyperglycemia. As a result, caution should be exercised in the application of only one metabolic dysfunction criterion to diagnose metabolic dysfunction-associated steatotic liver disease, as suggested in the 2023 nomenclature document, particularly in individuals exceeding weekly alcohol use thresholds of 140 g for women and 210 g for men. Additionally, metabolic dysfunction and alcohol use should be reassessed over time. This approach could ensure a more accurate prognosis and effective management of SLD addressing both metabolic and alcohol-related factors.

Objective To explore the differences in terahertz(THz)signal characteristics between normal and ischemic liver tissues of New Zealand rabbits using THz time-domain spectroscopy(THz-TDS),thereby providing a novel detection technique for the pathological detection of liver tissues.Methods Liver ischemia models were established in New Zealand rabbits.The THz scanning signal maps of normal and ischemic liver tissues were obtained using a reflective THz-TDS system,and the acquired signals were subjected to principal component analysis.Results Both normal and ischemic liver tissues displayed two distinct peaks in their THz signals.However,the amplitude of the THz signal in ischemic liver tissue was higher than that in normal liver tissue,with significant differences also observed in their signal morphologies.Principal component analysis results revealed a clear clustered distribution between the signals of normal and ischemic liver tissues,indicating that THz-TDS could effectively distinguish between the two tissue types.Conclusion THz-TDS can be applied to the detection of ischemic liver tissue,providing experimental evidence to support further research on the early diagnosis of liver ischemia and exhibiting broad prospects for clinical application.

Objective To explore the neurophysiological signatures of auditory event-related potentials(AERP)during propofol-induced graded sedation depths,and their correlations with sedation levels and behavioral responsiveness,and further to evaluate the feasibility of AERP components as potential biomarkers for quantifying consciousness states.Methods An auditory Oddball paradigm was used to evoke AERP responses in healthy volunteers under propofol-induced graded sedation.Linear mixed model was applied to explore the relationships between the mean amplitudes of AERP components[mismatch negativity(MMN);P300]and both sedation-induced conscious states[Modified Observer's Assessment of Alertness/sedation Scale(MOAA/S)scores]and behavioral performance(response accuracy).Results Twenty-two healthy volunteers were included.Data analysis revealed significant negative correlations between the mean amplitudes of MMN components[MMN-Dev:β=-0.62(-2.70--0.07),P=0.04;MMN-Nov:β=-0.15(-0.27--0.03),P=0.02]and MOAA/S scores during propofol sedation.Novel stimulus-evoked MMN amplitudes also correlated with response accuracy[MMN-Nov:β=-5.08(-7.78--2.37),P<0.01].There was a weak positive correlation between novel stimulus-evoked P300 amplitudes and MOAA/S scores[β=0.16(0.04-0.39),P=0.04],however,the correlation was no significant difference after adjusting for confounding factors including age,education level,and cognitive level.Conclusion The mean amplitude of MMN component elicited during auditory tasks was correlated with conscious states and behavioral accuracy under propofol-induced graded sedation.MMN holds promise as a potential neurophysiological indicator for quantifying conscious states or behavioral responsiveness during sedation.

Objective The objective of this study was to analyze the mortality and changing trend of head and neck cancer(nasopharyngeal cancer,laryngeal cancer,thyroid cancer,and oral cancer)in cancer registry areas of Inner Mongolia Autonomous Re-gion from 2010 to 2020,and to provide a scientific basis for the prevention and control of head and neck cancer in Inner Mongolia Au-tonomous Region.Methods The mortality data for head and neck cancers(nasopharyngeal cancer,laryngeal cancer,thyroid cancer,and oral cancers)in the tumor registration database of Inner Mongolia Autonomous Region from 2010 to 2020 were sorted out,and the China standard mortality of head and neck were calculated by gender,urban and rural areas,and cancer types.The average annual per-centage change(AAPC)was analyzed using Joinpoint 4.9.1.0 software to assess the trend of China standard mortality of head and neck cancers and cancer types.Results The China standard mortality of head and neck cancers in cancer registry areas of Inner Mongolia was 2.85/100,000.The China standard mortality of males(4.24/100,000)was higher than that of females(1.53/100,000),and the China standard mortality in rural areas(2.93/100,000)was higher than that in urban areas(2.79/100,000).The China standard mortality of oral cancer was the highest at 1.16/100,000,and the China standard mortality of nasopharyngeal cancer was the lowest at 0.42/100,000.From 2010 to 2020,the mortality of head and neck cancers increased by an average annual rate of 3.79%(95%CI:1.45%-6.17%),and the trend was statistically significant(P=0.005).The mortality of male head and neck canc-er increased by an annual rate of 7.27%(95%CI:3.05%-11.65%),and the trend was statistically significant(P=0.003).The mortality of females decreased by an average annual rate of 1.08%(95%CI:-4.51%-2.47%),and the trend was not statistically significant(P=0.500).The mortality of oral cancer showed an upward trend with an AAPC of 7.35%(P=0.040),and the mortality of laryngeal cancer,thyroid cancer and nasopharyngeal cancer showed no statistically significant trend(AAPC was3.36%,1.38%and-0.36%,respectively,P>0.05).Conclusion The mortality of head and neck cancer in cancer registry areas of Inner Mongolia Au-tonomous Region showed an upward trend from 2010 to 2020.The prevention and treatment of head and neck cancer should be paid to attention,with rural areas and male groups as the key prevention and control targets.The control measures should be strengthened for high-risk behaviors such as occupational exposure and alcohol consumption,oral cancer prevention and control should be focused on,and HPV vaccination and tobacco control policies should be strengthened.
