Based on the theoretical framework of "grease-turbidity-heat toxin"， this paper elucidates the patholo-gical evolution pattern underlying the alternation between active and remission phases of inflammatory bowel disease （IBD）. It is proposed that the active phase of IBD represents a progressive and explosive process characterized by internal accumulation of grease turbidity， constraint transforming into heat， and exuberant heat generating toxin. During the remission phase， the pathogenic process manifests as subsidence of heat toxin， depletion of qi and yin， latent retention of residual turbidity， and a state of coexistence between deficiency of healthy qi and lingering pathogenic factors. Accordingly， a staged therapeutic strategy with dynamic intervention and targeted modulation has been established. During the active phase， treatment follows the sequential principle of unblocking， clearing， and resolving pathogenic factors. In the early stage， the therapeutic approach focuses on regulating qi movement， fortifying the spleen， and resolving turbidity， using Tongxie Essential Formula （痛泻要方） and Shenling Baizhu Powder （参苓白术散） to regulate qi and fortify spleen. In the middle stage， the strategy emphasizes clearing heat， eliminating dampness， and dispersing pathogenic accumulation through downward and outward pathways， and Gegen Qinlian Decoction （葛根芩连汤） combined with Banxia Xiexin Decoction （半夏泻心汤） is used to clear and resolve damp-heat. In the late stage， treatment aims to resolve toxin， restrain sore， cool blood， and stabilize collaterals， using Baitouweng Decoction （白头翁汤）， Shaoyao Decoction （芍药汤）， and Xijiao Dihuang Decoction （犀角地黄汤） to eliminate toxins and cool blood. During the remission phase， the principle of reinforcing， consolidating， and penetrating is adopted to restore internal balance and clear the source， using Sishen Pills （四神丸） and Sijunzi Decoction （四君子汤） to reinforce healthy qi and venting pathogens.

Based on the theory of Zi Wu Liu Zhu （子午流注， the ebb and flow of midnight and midday） and the clinical characteristics of diarrhea-predominant irritable bowel syndrome （IBS-D） that its symptoms mainly occur during chou （丑） period （01：00—03：00）， mao （卯） period （5：00—7：00）， and si （巳） period （9：00—11：00）， this paper proposes a temporal pathogenesis chain of "liver constraint during chou period， intestinal stagnation during mao period， and spleen deficiency during si period". Within this chain， liver constraint serves as the initiating factor， and intestinal stagnation manifests as the branch， while spleen deficiency constitutes the root of the disease. Accordingly， a chronotherapeutic principle of "soothing the liver， regulating the intestines， and fortifying the spleen" is proposed， establishing a corresponding time-based syndrome differentiation and treatment system. During chou period， the treatment should focus on soothing the liver to relieve constraint and calming the mind to tranquilize the spirit， thereby blocking the mechanism of liver constraint overacting on the spleen. During mao period， the focus is regulating qi to resolve dampness and harmonizing the intestine to alleviate the branch symptoms of morning abdominal pain and diarrhea. During si period， the suggested method is fortifying the spleen and supplementing qi to drain dampness and stop diarrhea， thereby restoring the pivot of spleen-stomach transportation and transformation. These methods are complemented by strategies to optimize medication compliance， thereby providing a new chronotherapeutic approach for clinical diagnosis and treatment of IBS-D.

ObjectiveTo collate and compare the characteristics and differences in the methods for constructing animal models of different subtypes of gastroesophageal reflux disease （GERD） based on literature， providing a reference for researchers in this field regarding animal model construction. MethodsExperimental studies related to GERD including reflux esophagitis （RE）， nonerosive reflux disease （NERD） and Barrett's esophagus （BE） model construction from January 1， 2014 to January 27， 2024， were retrieved from databases such as CNKI， Wanfang， VIP， Web of Science， and Pubmed. Information on animal strains， genders， modeling methods including disease-syndrome combination models， modeling cycles were extracted； for studies with model evaluation， the methods of model evaluation were also extracted； then analyzing all those information. ResultsA total of 182 articles were included. SD rats were most frequently selected when inducing animal models of RE （88/148， 59.46%） and NERD （9/14， 64.29%）. For BE， C57BL/6 mice were most commonly used （11/20， 55.00%）. Male animals （RE： 111/135， 82.22%； NERD： 11/14， 78.57%； BE： 10/12， 83.33%） were the most common gender among the three subtypes. The key to constructing RE animal models lies in structural damage to the esophageal mucosal layer， gastric content reflux， or mixed reflux， among which forestomach ligation + incomplete pylorus ligation （42/158， 26.58%） was the most common modeling method； the key to constructing NERD animal models lies in micro-inflammation of the esophageal mucosa， visceral hypersensitivity， and emotional problems， and intraperitoneal injection of a mixed suspension of ovalbumin and aluminum hydroxide combined with acid perfusion in the lower esophagus （8/14， 57.14%） was the most common modeling method； the key to constructing BE animal models lies in long-term inflammatory stimulation of the esophageal mucosa and bile acid reflux， and constructing interleukin 2-interleukin 1β transgenic mice （7/25， 28.00%） was the most common modeling method. Adverse psychological stress was the most common method for inducing liver depression. ConclusionsThe construction key principles and methodologies for RE， NERD， and BE animal models exhibit significant differences. Researchers should select appropriate models based on subtype characteristics （e.g.， RE focusing on structural damage， NERD emphasizing visceral hypersensitivity）. Current studies show insufficient exploration of traditional Chinese medicine disease-syndrome combination models. Future research needs to optimize syndrome modeling approaches （e.g.， composite etiology simulation） and establish integrated Chinese-Western medicine evaluation systems to better support mechanistic investigations of traditional Chinese medicine.

ObjectiveTo analyse the current implementation status of Chinese herbal medicine （CHM） placebo and systematically evaluate the placebo effect in randomised controlled trials （RCTs） of traditional Chinese medicine （TCM） for the treatment of functional dyspepsia （FD）. MethodsA combination of medical subject terms and free words was used to search six databases， including PubMed， EMBASE， Cochrane Library， Web of Science， China National Knowledge Infrastructure， and Wanfang， for RCTs with CHM placebo group for FD published from January 31st， 1994 to September 30th， 2023. The dosage forms， composition， and methodological quality were collected and evaluated. The quality of the included articles was evaluated by Cochrane risk of bias assessment tool， and meta-analysis was performed on the CHM placebo response rate of patients with FD， and subgroup analysis and meta-regression was performed according to diagnostic criteria， efficacy criteria， duration of treatment， type of placebo， whether it contained active ingredient， and whether it evaluated placebo effects. ResultsA total of 34 publications were included involving 5046 participants， of which 2221 FD patients received CHM placebo treatment. Granules were the predominant placebo preparation， accounting for 71% （24/34）； 32.35% （11/34） of the studies added real CHM to the placebo， and only 12 （35%） of the studies described appearance， odour， and taste. The placebo response rate in FD patients in the placebo group was 41% （95% CI： 0.35 to 0.47； P＜0.01， I² = 87%）； there was significant difference between groups with different diagnostic criteria and different treatment durations （P＜0.05 or P＜0.01）， but there was no significant difference between the different efficacy evaluation criteria， the different placebo preparation， the presence of a low-dose active ingredient， and the presence or absence of placebo assessment （P＞0.05）. ConclusionThere was a significant CHM placebo effect in patients with FD， with granules as the main preparation of placebop. Different diagnostic criteria and different treatment times may affect the response rate of patients， and the addition of low-dose real medicine to the CHM placebos has not been seen to have an effect on the response rate. Clinical investigators have not paid enough attention to placebos， and there is a lack of uniform standards and norms for the preparation and evaluation of CHM placebos.

Objective:Taking naval officers and soldiers who participate in military continuing education as an example, to compare the distribution of sensory learning style of learners with different personality in order to provide suggestions and references for online course teaching.Methods:By using convenient sampling method, MBTI (Myers-Briggs Type Indicator) and VARK (Visual, Aural, Read/Write, Kinesthetic questionnaire) were measured in the Navy. A total of 10 000 questionnaires were distributed and 8 124 valid ones were collected. Through analysis of SPSS 25.0 software, the personality dimensions and personality types were analyzed for personality analysis, and the main indicators of sensory learning style analysis were tendency multiplicity, the intensity and distribution of single sensory learning style, and specific sensory learning styles. The Chi-square test was adopted, with test level of α=0.05. Results:It showed statistical differences in the tendency multiplicity and intensity of single style among officers and soldiers in the three dimensions of extroversion-introversion, sensing-intuition and judging-perception ( χ 2=12.37, 18.02, 22.97, 12.57, 12.73, 24.45, P=0.005, <0.001, <0.001, =0.006, =0.005, <0.001). It showed statistical differences in the distribution of single style and the specific sensory learning styles among officers and soldiers in all the four dimensions of extroversion-introversion, sensing-intuition, thinking-feeling, and judging-perception ( χ 2=28.30, 36.96, 11.40, 41.95, 53.76, 75.48, 43.11, 77.29, P <0.001, <0.001, =0.022, <0.001, <0.001, <0.001, <0.001, <0.001). It showed statistical differences in the tendency multiplicity, the intensity and distribution of single style, and the specific sensory learning styles among naval officers and soldiers with different personality types ( χ 2=86.63, 96.22, 147.41, 363.76, all P<0.001). Conclusions:Personality dimension has influence on sensory learning style, especially for extroversion-introversion, sensing-intuition, and judging-perception dimensions. Personality type has an important influence on the tendency multiplicity, distribution type and performance intensity of sensory learning style. It is integral part of online course teaching to meet the diversified and personalized learning needs of officers and soldiers.

Spleen deficiency is an important part of the theoretical system of Traditional Chinese Medicine,which has experienced the process of origin,standardization,maturity,perfection and development in different historical periods.The physiological function of the spleen in Traditional Chinese Medicine involves"the spleen governs transportation and transformation,promotes blood circulation";The study of"spleen governing transportation and transformation"divided into"spleen governing transportation"and"spleen governing transformation"from the function of spleen,which is more conducive to explaining the scientific connotation of spleen governing transportation and transformation.Spleen governing transport and transformation is the basis of spleen governing clearing,and spleen governing clearing is the purpose of spleen governing transport and transformation.Spleen governing blood circulation is the outcome of spleen governing clearing,and there is a progressive logical hierarchy relationship between them.With the rise of proteomics,metabonomics and intestinal flora research,it provides technical support for the study of spleen deficiency syndrome;In addition,based on the correlation between spleen of Traditional Chinese Medicine and the functions of endoplasmic reticulum,the material basis of essence of spleen deficiency is discussed from the perspective of endoplasmic reticulum stress,which provides a new direction for the study of spleen deficiency.
