The theory of "Yang transforming Qi while Yin constituting form" in the Huangdi's Internal Classic is derived from the application, transformation, movement, and balance of Tao. It is highly condensed, revealing the true meaning of Tao and guiding the changes and progress of all natural things, including diseases. Therefore, the appearance of various physical diseases is the manifestation of Yin-Yang Qi transformation. Sweat pore, formed by the Qi transformation of Yin and Yang, is the nourishing and regulating system. It serves as the hub and channel, assisting in the flow and transformation of Qi, facilitating the exchange of material, energy, and information with the outside world. With sweat pore as the hub and based on the macro-control and holistic thinking of "Yang transforming Qi while Yin constituting form", this paper explores the microscopic mechanisms underlying chronic liver disease. In combination with the roles of mitochondria, exosomes, and the ultraliver sieve structure in the formation and progression of chronic liver disease, this paper elucidates the close internal relationship between the disease's initial quality, symptom signs, and its physiological and pathological functions under the guidance of this theory. Modern studies have shown that autophagy, intestinal flora disorders, glucose and lipid metabolism disturbances, activation of inflammatory factors, ferroptosis, and other microscopic pathological mechanisms are involved in the occurrence and development of chronic liver disease. The common connotation of the Yin-Yang concept in traditional Chinese medicine (TCM) and the pathological mechanisms in modern medicine is deeply analyzed. The corresponding relevant microscopic mechanisms and the guiding role of the theory of "Yang transforming Qi while Yin constituting form-sweat pore" in the management of chronic liver disease are summarized. Wind medicine promotes growth and transformation through sweat pore. The combination of pungent and sweet medicines facilitates Yang and disperse Yin. The formulas, combining the characteristics of wind medicine and pungent and sweet medicines, fit the principle of "Yang transforming Qi while Yin constituting form-sweat pore". This paper combines both macro and micro perspectives to explain the scientific connotation and microscopic mechanisms of chronic liver disease based on the theory of "Yang transforming Qi while Yin constituting form-sweat pore", and explore the prevention and treatment of chronic liver disease through the principles, methods, prescriptions, and medicines featured by combination of pungent and sweet medicines, facilitating Yang, activating sweat pore, and dispersing Yin, providing new ideas and reference for the clinical treatment of chronic liver disease.

ObjectiveTo investigate the therapeutic effect of sequential administration of Dihuang Baoyuan granules (DHBY, the prescription for consolidating body resistance) and Fuling Yunhua granules (FLYH, the prescription for treating symptoms) on spontaneous type 2 diabetes mellitus (T2DM) in mice. MethodsAccording to the fasting blood glucose (FBG) level, 12-week-old db/db mice were randomized into six groups: model, DHBY (18.02 g·kg-1), FLYH (14.80 g·kg-1), sequential administration 1 (SEQ-1, DHBY 18.02 g·kg-1+FLYH 14.80 g·kg-1), sequential administration 2 (SEQ-2, FLYH 14.80 g·kg-1+DHBY 18.02 g·kg-1), and dapagliflozin (Dapa, 1.3 mg·kg-1). The m/m mice in the same litter were selected as the normal group. The mice were administrated with corresponding drugs by gavage for 8 consecutive weeks. During the 8 weeks of drug administration and 2 weeks after withdrawal, the retinal thickness, FBG, hemoglobin A1c (HbA1c), and insulin were determined, and histopathological changes of the pancreas, liver, kidney, and retina were observed by hematoxylin-eosin (HE) staining. ResultsCompared with the model group, SEQ-1 for 4 weeks lowered the FBG level (P<0.05), raised the insulin level, decreased the triglyceride (TG) level (P<0.05), increased the number of optic ganglion cells and diminished vacuolar degeneration of pancreatic islet and liver. SEQ-2 lowered FBG and HbA1c levels (P<0.05), rose the insulin level, increased the retinal thickness and the number of optic ganglion cells (P<0.05), and alleviated vacuolar degeneration of pancreatic islet and liver. Two weeks after drug withdrawal, Dapa tended to increase FBG and HbA1c compared with those at the time of drug withdrawal. However, the levels of FBG and HbA1c in the SEQ-2 group remained decreasing (P<0.05). ConclusionSEQ-1 and SEQ-2 can lower the blood glucose level and ameliorate diabetic retinopathy, and SEQ-2 outperformed DHBY and FLYH in lowering the blood glucose level. Moreover, SEQ-2 can maintain the blood glucose-lowering effect after drug withdrawal.

Journal of Apoplexy and Nervous Diseases 2025;42(5):395-400
Glycogen storage disease type Ⅱ (GSD Ⅱ), also known as Pompe disease, is a common autosomal recessive lysosomal storage disease with predominantly muscle tissue involvement, and it is caused by defects in the GAA gene which encode acid α-D-glucosidase in lysosomes. According to the age of onset and the main organs involved, it is classified into infant-onset Pompe disease (IOPD) and late-onset Pompe disease(LOPD). The diagnosis of this disease depends on the reduction in GAA enzyme activity, the detection of GAA gene mutations, and muscle tissue biopsy, and early diagnosis and treatment are crucial for prognosis. Recombinant human GAA(rhGAA) enzyme replacement therapy prepared by the gene recombination technology is currently the main disease-modifying treatment method for Pompe disease, among which the earliest drug alglucosidase α has shown good efficacy in improving muscle strength and respiratory function and prolonging survival time, and the new-generation rhGAA drugs avalglucosidase α and cipaglucosidase alfa provide new options, especially for patients with poor outcomes and severe symptoms. Substrate ablation therapy and gene therapy are still under exploration, and disease-modifying therapies combined with nutritional and exercise therapies and multidisciplinary long-term management will achieve twice the result with half the effort.

Objective:To construct a teaching ability evaluation system for diversified general medicine course teachers under the guidance of "one practice and three learning".Methods:A research group was established to search for relevant documents and literature. A framework of evaluation index system was established through drafting and repeated discussion and modification by members of the group, as well as further discuss and modification by experts in general medicine. The framework was used to develop an expert consultation questionnaire on the teaching ability evaluation system for diversified general medicine course teachers under the guidance of "one practice and three learning". Through two rounds of expert consultation, a teaching ability evaluation system for diversified general medicine teachers under the guidance of "one practice and three learning" was constructed. A questionnaire was developed according to the system. The rationality and scientificity of the evaluation index system were verified by questionnaire survey.Results:The teaching ability evaluation system for diversified general medicine teachers under the guidance of "one practice and three learning" included 3 first-level indicators, 15 second-level indicators, and 41 third-level indicators. The general medicine curriculum evaluation questionnaire developed on the system showed that the Cronbach's α coefficient of the overall evaluation system was 0.981. The Cronbach's α coefficients of first-level indicators, including general medicine teaching plan, diversified theory and practice teaching, and comprehensive ability cultivation under the guidance of "one practice and three learning" ideology, were 0.920, 0.919, and 0.923, respectively. The content validity index (S-CVI) of the system was 0.981, and the content validity index (I-CVI) of indicators were 0.826-1.000. The correlation coefficients of first-level indicators and the system were 0.837-0.942 (all P<0.05). The correlation coefficients of second-level indicators and their corresponding first-level indicators were 0.586-0.971 (all P<0.05). The correlation coefficients of third-level indicators and their corresponding first-level indicators were 0.412-0.904 (all P<0.05). Conclusions:Under the guidance of "one practice and three learning", the teaching ability evaluation indicators for diversified general medicine course teachers have high specificity, rationale structure, high feasibility, high reliability, and high practicability. This evaluation system can provide theoretical reference for the training of undergraduate students in general medicine.
