Psoriasis is a common chronic inflammatory systemic disease in dermatology. Its high prevalence， recurrence rate， and numerous comorbidities impose a significant physical and mental burden on patients. With the continuous advancement of modern medicine， the emergence of biological agents has improved clinical efficacy， making it possible to overcome psoriasis， in addition to classical treatments. However， in clinical practice， adverse reactions， drug resistance， recurrence rates， and immune drift cannot be ignored. Traditional Chinese medicine （TCM） has a history of thousands of years in treating psoriasis， demonstrating good efficacy， high safety， and a low recurrence rate， but a standardized management system is lacking. Therefore， the 25^th Clinical Diseases Responding Specially to TCM Treatment Series （Psoriasis） Youth Salon， hosted by the Chinese Association of Chinese Medicine and organized by the Youth Committee of the Chinese Association of Chinese Medicine， invited 29 experts and scholars from TCM， Western medicine， and interdisciplinary fields to actively discuss the "Advantages， Challenges， and Clinical Transformation of TCM and Western Medicine in the Diagnosis and Treatment of Psoriasis". The experts at the meeting concluded that the advantages of TCM in the treatment of psoriasis are as follows. Firstly， in the TCM-led treatment plan， TCM's understanding of psoriasis follows the principle of combining the differentiation of disease and syndrome. This approach distinguishes the basic contradiction from the current main contradiction and enables a clear grasp of the dynamic process of psoriasis development. Based on the system of syndrome differentiation and treatment， TCM intervention is applied to address the current main contradiction， and the optimal TCM treatment plan is formulated by combining internal and external treatments. Adhering to the principle of "what is visible outside must be addressed inside"， TCM can prevent and treat psoriasis comorbidities early by differentiating syndrome types. Secondly， in the integrated TCM and Western medicine treatment plan， the combination of both methods not only enhances efficacy but also reduces the adverse reactions of immunosuppressants and biological agents， lowering the recurrence rate. This conference provides a reference for the diagnosis and treatment of psoriasis using TCM and integrated TCM and Western medicine， opening up new ideas for clinical and basic research and guiding future research directions.

Objective: To investigate the status quo and associated factors of drinking water knowledge, attitude and behavior among primary school students in rural areas, so as to provide evidence for health behavioral intervention of drinking water in primary school. Methods: Twentythree primary schools in rural area from Hebei, Henan, Shandong and Shanxi provinces were selected by using purposive sampling method from March 1 to April 27 in 2023. Selfdesigned questionnaires regarding knowledge, attitude and behavior of drinking water were distributed to all students in grade 3-6, and 2 173 valid questionnaires were obtained. Multivariate Logistic regression was used to analyze the influencing factors of drinking water knowledge, attitude and behavior of primary school students. Results: The attainment rates of drinking water knowledge, attitude and behavior level were 20.02%, 26.65%, and 31.20%, respectively, among primary school students. The median of daily water intake was 1 000 mL, and the average daily water intake was (1 172.99±771.89)mL. In addition, 66.31% of students water intake reached the minimum standard of 800 mL recommended. The results of multiple Logistic regression indicated that drinking water accessibility in school, health education of drinking water, and individual selfcontrol ability were positively correlated with the knowledge (OR=1.31, 1.57, 1.58), attitude (OR=2.07, 1.65, 1.73), behavior (OR=1.40, 1.49, 1.91) of drinking water and daily water intake (OR=1.41, 1.38, 1.20) (P<0.05). Conclusions Primary school students in rural areas are generally lack of appropriate health awareness on drinking water including knowledge, attitude and behavior. Schools should take targeted measures to focus on the cultivation of students selfcontrol ability, so as to improve students knowledge and attitudes of drinking water, and furthermore help students shape their healthy behaviors of drinking water.

Oral lichen planus (OLP) is a common chronic inflammatory disease and potentially malignant disorder of the oral mucosa. Clinical manifestations include bilateral symmetrical distributions of pearly white reticular streaks, and its subtype erosive oral lichen planus (EOLP) is often accompanied by local congestion, erosion, obvious pain, and other symptoms, which affects the patient's eating and swallowing. Oral hygiene and environmental factors, lifestyle and dietary factors, psychological factors, medication factors, and systemic disease factors all contribute to the recurrence of EOLP lesions, which increases the cancer potential of this condition. Therefore, measures to prevent the recurrence and cancerous transformation of EOLP have attracted much attention. In the clinical treatment strategy for EOLP, attention should be given to its influencing factors for comprehensive management. Patients should be provided with multidisciplinary and multifaceted oral comprehensive management measures across the following strategies: maintaining a good oral hygienic environment, dietary therapies and healthy living habits, psychological therapies, systemic/local therapeutic guidance, and active follow-up and treatment of systemic diseases. This article provides multidisciplinary and multifaceted comprehensive oral management measures for patients with the goal of cancer prevention, minimizing recurrence, and improving the quality of life of patients.

To implement the Opinions of the State Council of the Central Committee of the Communist Party of China on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine， delve into the diseases specifically responding to traditional Chinese medicine （TCM）， and serve the building of advantageous specialties， clinical talent cultivation， national research layout， and academic innovation， the Chinese Association of Chinese Medicine sponsored the salons in multiple fields to discuss the diseases specifically responding to TCM. On August 26， 2023， the 25^th salon on the diseases specifically responding to TCM was held in Shanghai. In view of the advantages of TCM and integrated traditional Chinese and Western medicine in the diagnosis and treatment of psoriasis， Chinese and western medicine experts and interdisciplinary researchers carried out extensive and in-depth discussions and formed specific suggestions and consensus on the diagnosis and treatment of psoriasis with TCM and integrated traditional Chinese and Western medicine. However， there was still a lack of detailed research path. Under the guidance of the Chinese Association of Chinese Medicine， this paper analyzes the problems in the diagnosis and treatment of psoriasis from the occurrence and development of psoriasis. According to the advantages and characteristics of TCM and integrated traditional Chinese and Western medicine in the diagnosis and treatment of psoriasis， this paper puts forward the main points of research layout for psoriasis from the three aspects of psoriasis diagnosis and treatment， comorbidity prevention， and chronic disease management as follows： ① optimization of the syndrome differentiation system for psoriasis， ② optimization of assessment indicators for psoriasis， ③ recurrence mechanisms of psoriasis， ④ construction and research of TCM prevention and treatment of psoriasis recurrence， ⑤ construction of the comorbidity spectrum and TCM theoretical system of psoriasis， ⑥ comorbidity mechanisms of psoriasis. Furthermore， this article proposed the research layout and directions， expected goals and values， and funding priorities. Therefore， on the basis of the series of salons about psoriasis as a disease specifically responding to TCM， this article puts forward the research paradigm of psoriasis， aiming to facilitate the high-quality development of TCM and provide reference for the national research layout， the research and development of new TCM preparations， the selection of research topics， and the formulation of guidelines and consensus.

Objective: To investigate if high glucose (HG) exacerbates Porphyromonas gingivalis (P.g) lipopolysaccharide (LPS)-induced inflammatory response in human gingival fibroblasts (HGFs) and to explore the underlying mechanisms. To provide a basis for the mechanism of diabetes aggravating periodontitis. Methods: HGFs were divided into four groups: the control group (basal medium), the LPS group (treated with 5 μg/mL P.g-LPS for 24 h), the HG group (treated with 25 mmol/L glucose for 24 h), and the HG+LPS group (treated with 25 mmol/L glucose + 5 μg/mL P.g-LPS for 24 h). After culturing for 24 h in the respective media, the cells were harvested for experiments. Intracellular reactive oxygen species (ROS) and mitochondrial reactive oxygen species (mtROS) were detected using 2 ', 7' - dichlorodihydrofluorescein diacetate (DCFH-DA) and MitoSOX Red staining, respectively. Fluorescence intensity was analyzed by confocal fluorescence microscopy and directly measured in cell suspension. Immunofluorescence was used to detect changes in mitochondrial DNA (mtDNA) content of HGFs. Real-time fluorescence quantitative PCR was used to detect the content of mtDNA in cytoplasm and cell supernatant. Protein expression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was assessed by western blot, while mRNA expression levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) were detected by PCR. Results: Compared to the control group, both the LPS group and the HG group exhibited a significant increase in ROS and mtROS, with a more pronounced elevation in the HG+LPS group, demonstrating a synergistic effect (ROS: F = 396.5, P < 0.001; mtROS: F = 29.38, P < 0.001, CI < 1). The cytoplasmic mtDNA content was significantly elevated in the LPS group, with a more marked increase in the HG+LPS group (F = 27.85, P < 0.001). The supernatant mtDNA levels were significantly higher in both the LPS and HG groups, with a more pronounced elevation in the HG+LPS group (F = 15.26, P < 0.001). The phosphorylated proteins p-STING, p-TBK1, and p-P65 in the cGAS-STING pathway showed varying degrees of activation in the LPS and HG groups, reaching the highest levels in the HG+LPS group (p-STING: F = 52.67, P < 0.001; p-TBK1: F = 15.67, P = 0.001; p-P65: F = 9.83, P = 0.005), while p-IRF3 showed no significant differences among the groups (P = 0.072). Pro-inflammatory cytokine TNF-α was significantly higher in the HG+LPS group compared to the control group (F = 15.05, P < 0.001), and IL-1β increased in both the LPS and HG groups, with a more pronounced rise in the HG+LPS group (F = 30.98, P < 0.001). IL-6 showed no significant differences among the groups (P = 0.847). Conclusion High glucose and LPS act synergistically to enhance oxidative stress, accompanied by increased mtDNA release, which activates the cGAS-STING pathway, thereby amplifying the inflammatory response in HGFs.

Objective: To investigate whether melatonin (MT) secretion in different parts of the gastrointestinal tract (GIT) exhibits seasonal variations and its correlation with immune regulation. Methods: Sixty Sprague-Dawley rats were divided into control and model groups, and the pineal gland was removed in the model group. Stomach, jejunum, ileum, and colon tissues were obtained during the spring equinox, summer solstice, beginning of autumn, autumn equinox, and winter solstice. The levels of MT, MT receptors (MR), arylalkylamine N-acetyltransferase (AANAT), hydroxyindole-O-methyltransferase (HIOMT), interleukin-2 (IL-2), and interleukin-10 (IL-10) in the GIT were measured using enzyme-linked immunosorbent assay. Results: Except for the stomach, the jejunum, ileum, and the colon showed seasonal tendencies in MT secretion. In the control group, MT secretion in the jejunum and ileum was the highest in the long summer, and colonic MT secretion was the highest in winter. In the model group, MT levels in the colon were highest in the summer. The seasonal rhythms of the MR, AANAT, HIOMT, IL-2, and IL-10 in the colon were roughly similar to those of MT, and changed accordingly after pinealectomy. Conclusions Gastrointestinal MT secretion is related to seasonal changes, and MT secretion in each intestinal segment is influenced by different seasons. The biological effects of MT in the gut are inextricably linked to the mediation of MR, and a hormone-receptor linkage exists between MT and MR. The effect of seasonal changes on the gastrointestinal immune system may be mediated through the regulation of seasonal secretion of MT.

Objective:By analyzing the cost change trend,internal structure change and main influencing factors of diabetes inpatients'hospitalization expenses,it provides empirical basis for promoting the reform of medical service prices,optimizing the internal structure of hospitalization expenses,effectively controlling hospitalization expenses,and reducing the economic burden of diabetes inpatients.Methods:Using the first page data of medical records of 13 426 diabetes inpatients in the target hospital from 2017 to 2021,it analyzes the structural change of diabetes inpatients'hospitalization expenses by using structural change degree and grey correlation degree methods,and analyzes the influencing factors of hospitalization expenses by using linear regression and BP neural network model.Results:Drug expenses and medical technology expenses are the top two in the proportion of total hospitalization expenses of discharged patients with diabetes,and they account for a large proportion in the total hospitalization expenses.The results of structural change and grey correlation show that drug expenses and medical technology expenses are these two factors that cause changes in the total hospitalization cost structure and have a high correlation with the total hospitalization cost,with a cumulative contribution rate of 90.50％.According to the results of linear regression and neural network model,the length of stay is the most important factor affecting the total cost of hospitalization of diabetes patients,followed by the number of operations/procedures and diagnoses.Conclusion:The internal composition of hospitalization expenses for diabetes patients is unreasonable.The proportion of drug expenses and medical technology expenses is too high.The proportion of medical and nursing expenses reflecting the technical labor value of medical personnel is relatively low.The structure of medical income needs to be further optimized.The length of stay is the most critical factor affecting the hospitalization expenses of diabetes patients.Reasonable control of the length of stay can effectively control the unreasonable growth of medical expenses and reduce the economic burden of diabetes patients.

ObjectiveTo explore the suitability of four qualitative research methods in the development of TCM scale. MethodsTaking the development of "Seven Emotions Scale" as an example， we conducted semi-structured interviews with 31 patients of emotional disorders and 10 healthy people by objective sampling， and collected psychological feelings and emotional cognition data related to seven emotions according to the interview outline. Two qualitative methods， descriptive qualitative research and descriptive phenomenology， were used to analyze the data and construct the item library of the scale. The conceptual framework of the scale was constructed by using commonly used grounded theory and frame analysis. ResultsDuring data analysis， it is found that the themes extracted from descriptive phenomenology were not easily understood by the interviewees， and it is difficult for the researchers to truly achieve the "suspension" required by phenomenology. Considering the feasibility and convenience of the researchers' actual operation， as well as whether the initial purpose of the scale research can be intuitively included in the interviewees' views and feelings， descriptive phenomenology is not suitable for the formation of scale items. Using descriptive qualitative research method to analyze the interview data of healthy people and patients with emotional disorders， 306 and 476 scale items were obtained respectively. Through grounded theory， five selective codes were obtained： physical symptoms， external manifestations， psychological feelings， behaviors and emotional control. Using frame analysis， four themes including physical symptoms， psychological feelings， behavior and emotional cognition were constructed. Both methods can be used to construct the conceptual frame of scale， but the framework analysis is more convenient and can better ensure the transparency of the research. ConclusionDescriptive qualitative research methods can be used to form the item library of TCM scales. Framework analysis is more suitable for the construction of the conceptual framework of the scale than grounded theory， while descriptive phenomenology is not suitable for the development of TCM scales.

OBJECTIVE To investigate the effects of dexmedetomidine （DEX）-assisted general anesthesia on hemodynamics and cognitive function in elderly patients undergoing painless enteroscopy. METHODS From July 2020 to February 2022， 180 elderly patients undergoing painless enteroscopy in the outpatient operating room of the Second People’s Hospital of Jiaozuo were selected and divided into a control group （n＝90） and an observation group （n＝90） according to the random number table method. The control group was given routine general anesthesia （induced with sufentanil and propofol anesthesia， maintained with propofol anesthesia）， while the observation group was given DEX-assisted general anesthesia after preoperative preparation. The hemodynamic indexes [mean arterial pressure （MAP）， heart rate （HR）]， dosage of general anesthesia， awakening time， cognitive function [minimized mental status examination （MMSE）]， and the incidence of adverse drug reactions were compared between the two groups. RESULTS There was no significant difference in various indicators before anesthesia （T0） between 2 groups （P＞ 0.05）. Compared with T0， MAP and HR of the two groups were reduced significantly 10 minutes after anesthesia （T1）， at the time of enteroscope reaching the ileum and cecum （T2）， enteroscope withdrawal after the examination （T3）， and 10 minutes after surgery （T4）； but MAP and HR of the observation group at T1， T2， T3， and T4 were all higher than those of the control group （P＜0.05）. Compared with the control group， the dosage of general anesthesia and the recovery time in the observation group were significantly reduced or shortened， the MMSE scores at 1， 2 and 3 days after the operation were significantly increased， while the incidence of cognitive dysfunction and adverse reactions were significantly reduced （P＜0.05）. CONCLUSIONS DEX can effectively improve the hemodynamics and cognitive function of elderly patients undergoing painless enteroscopy， which is beneficial to reduce the dosage of general anesthesia， shorten recovery time， and has better safety.
