ObjectiveTo screen suitable packaging and storage conditions for small packaged Alismatis Rhizoma decoction pieces, laying the foundation for developing standardized storage, maintenance techniques and determining shelf life. MethodsUsing the accelerated stability test method, the small packaged decoction pieces of Alismatis Rhizoma were placed in polyethylene plastic bags, aluminum foil polyethylene composite bags, and cowhide coated paper bags under temperature of (40±2) ℃ and relative humidity of (75±5)% conditions, the quality testing was conducted at the end of the 0th, 1st, 2nd, 3rd, and 6th month, respectively. Using long-term stability test method, an orthogonal experiment was designed to investigate storage conditions, packaging materials, and packaging methods. At the end of the 0th, 1st, 3rd, 6th, 9th, 12th, 18th, and 24th month, the quality of small packaged Alismatis Rhizoma decoction pieces was tested under different packaging and storage conditions(including 2 packaging methods:vacuum packaging and sealed packaging, 3 storage conditions:room temperature, cool, and modified atmosphere, 3 packaging materials:cowhide coated paper bag, aluminum foil polyethylene composite bag, and polyethylene plastic bag). Then, the G1-entropy weight method combined with orthogonal experiment was used to analyze the quality changes of the decoction pieces under different packaging and storage conditions to identify optimal packaging and storage conditions. The quality testing indicators for Alismatis Rhizoma decoction pieces were expanded beyond those specified in the 2020 edition of the Pharmacopoeia of the People's Republic of China. In addition to the existing indicators(characteristics, moisture content, extractives, and the total content of 23-acetyl alisol B and 23-acetyl alisol C), new indicators including color value, water activity, total triterpenoid content, and alisol B content have been added. ResultsThe accelerated stability test results indicated that the quality of small packaged Alismatis Rhizoma decoction pieces was more stable when packaged in aluminum foil-polyethylene composite materials compared to cowhide-coated paper bags and polyethylene plastic bags. Analysis of the long-term stability test results using the G1-entropy weight method combined with orthogonal experiment revealed that storage conditions had the greatest impact on both raw and salt-processed products, followed by packaging materials, while the packaging method had the least influence. For both types of small packaged Alismatis Rhizoma decoction pieces, modified atmosphere storage demonstrated superior efficacy compared to cool storage or room temperature storage. Storage in aluminum foil-polyethylene composite bags was superior to polyethylene plastic bags or cowhide-coated paper bags. However, the stability of sealed raw products was better than vacuum-packed ones, whereas vacuum-packed salt-processed products exhibited greater stability than their sealed counterparts. ConclusionBased on the results of the quality changes of small packaged Alismatis Rhizoma decoction pieces under different storage conditions, it is recommended that the suitable storage packaging conditions for small packaged raw products are sealed packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage, and the suitable storage and packaging conditions for small packaged salt-processed products are vacuum packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage.
2.Advances in the mechanisms of endothelial-to-mesenchymal transition in corneal endothelial cell
International Eye Science 2026;26(1):35-38
Corneal endothelial cells(CECs), which form the innermost cellular layer of the cornea, play a pivotal role in sustaining corneal transparency and preserving visual acuity. However, CECs are vulnerable to damage induced by a spectrum of pathological conditions or traumatic injuries. Once the density of CECs declines below a critical threshold, corneal endothelial dysfunction is precipitated, ultimately leading to corneal edema and progressive visual impairment. Penetrating keratoplasty and corneal endothelial transplantation remain the first-line therapeutic strategies for managing advanced corneal endothelial dysfunction. Nevertheless, the global shortage of donor corneas severely limits the accessibility and scalability of these surgical interventions. Consequently, regenerative medicine approaches targeting corneal endothelial repair and regeneration have emerged as a major focus of international research in ophthalmology. A key challenge in the in vitro expansion of CECs is their propensity to undergo endothelial-to-mesenchymal transition(EndMT). EndMT is a process of cellular phenotypic transformation, through which endothelial cells lose their intrinsic functions and acquire the characteristic features of mesenchymal cells. The EndMT significantly impedes the clinical translation of in vitro-cultured CECs for regenerative applications. In this review, the risk factors and related signaling pathways involved in EndMT were summarized, aiming to provide references for the basic research and clinical treatment of relevant diseases.

Objective:
To explore the association between types of obesity and 10-year risk of atherosclerotic cardiovascular disease (ASCVD) among hypertensive patients, so as to provide the basis for formulating ASCVD prevention strategies for hypertensive patients.
Methods:
From January to December 2021, hypertensive patients who were under follow-up management and completed health examinations at three community health service centers in Linping District, Hangzhou City were selected by a cluster sampling method. Basic information, lifestyle, disease history, height, weight, waist circumference (WC), and blood biochemical indicators were collected through health examination data. Based on assessments of body mass index (BMI) and WC, participants were categorized into four types: non-obese, general obesity only, central obesity only, and combined obesity. The Prediction for ASCVD risk in China (China-PAR) was used to assess 10-year ASCVD risk, which was categorized as low, moderate, and high risk. Multivariable logistic regression models were used to analyze the association between different types of obesity and ASCVD risk among hypertensive patients.
Results:
A total of 10 408 hypertensive patients were included, with a median age of 68.00 (interquartile range, 10.00) years. There were 4 301 (41.32%) males and 6 107 (58.68%) females. The proportions of non-obese, general obesity only, central obesity only, and combined obesity were 34.93% (3 635 individuals), 22.85% (2 378 individuals), 4.32% (450 individuals), and 37.90% (3 945 individuals), respectively. There were 3 389 (33.52%) cases at high risk of ASCVD. Among them, high ASCVD risk was observed in 1 107 (30.45%), 896 (37.68%), 122 (27.11%), and 1 364 (34.58%) patients with non-obese, general obesity only, central obesity only, and combined obesity, respectively. Multivariable logistic regression analysis showed that after adjusting for gender, age, smoking, drinking, physical activity, and diabetes, the risk of high ASCVD in hypertensive patients with general obesity only and combined obesity was 1.383 times (95%CI: 1.235-1.548) and 1.225 times (95%CI: 1.109-1.354) that of non-obese hypertensive patients, respectively.
Conclusions
General obesity only and combined obesity can increase the 10-year high risk of ASCVD among hypertensive patients. It is necessary to strengthen comprehensive management of body weight and WC among hypertensive patients to reduce the risk of ASCVD.

ObjectiveTo study the clinical characteristics and influencing factors of rheumatoid arthritis (RA) in the patients with cold dampness obstruction syndrome. MethodsThe RA patients treated in the Department of Traditional Chinese Medicine and Rheumatology of the China-Japan Friendship Hospital from August 2022 to June 2024 were selected. The demographic information, clinical data, laboratory test results, and traditional Chinese medicine (TCM) symptom information were collected for syndrome differentiation, on the basis of which the characteristics and influencing factors of cold dampness obstruction syndrome were analyzed. ResultsA total of 258 RA patients were selected in this study, including 88 (34.1%) patients with cold dampness obstruction syndrome, 53 (20.5%) patients with dampness and heat obstruction syndrome, 31 (12.0%) patients with wind dampness obstruction syndrome, 29 (11.2%) patients with liver-kidney deficiency syndrome, 19 (7.4%) patients with Qi-blood deficiency syndrome, 14 (5.4%) patients with phlegm-stasis obstruction syndrome, 15 (5.8%) patients with stasis obstructing collateral syndrome and 9 (3.5%) patients with Qi-Yin deficiency syndrome. The patients were assigned into two groups of cold dampness obstruction syndrome and other syndromes. The group of cold dampness obstruction syndrome had lower joint fever, 28-tender joint count (TJC28), and 28-joint disease activity score (DAS28)-C-reactive protein (CRP) and higher central sensitization, cold feeling of joints, fear of wind and cold, cold limbs, and abdominal distention than the group of other syndromes (P<0.05). The binary logistic regression analysis showed that central sensitization (OR 5.749, 95%CI 2.116-15.616, P<0.001) and DAS28-CRP (OR 0.600, 95% CI 0.418-0.862, P=0.006) were the independent factors influencing cold dampness obstruction syndrome in RA. ConclusionCold dampness obstruction syndrome is a common syndrome in RA patients. It is associated with central sensitization, cold feeling of joints, abdominal distension and may be a clinical syndrome associated with central sensitization.

Malignant tumor metastasis is the key factor leading to poor prognosis of patients, and it is a difficult problem to be overcome in the field of tumor therapy. Metabolic reprogramming, as a key link in the regulation of tumor metastasis activity, affects the growth, invasion, and metastasis of tumor cells by changing the metabolic pathways of intracellular substances (such as glucose, amino acids, lipids, and nucleotides). In particular, metabolic reprogramming plays a key role in the multistage linked steps related to tumor metastasis and can play a crucial role in several key stages of tumor tissue dissociation in situ, hematogenous metastasis, and remote colonization. Malignant tumor cells can selectively adjust their own metabolic state to adapt to the growth conditions of different metastatic microenvironments and colonization sites and then choose the most favorable growth and metabolism strategy. According to the holistic concept of traditional Chinese medicine (TCM), the metastasis of malignant tumors is generally closely related to the metabolic state of the whole body. One of the advantages of TCM in the treatment of malignant tumors is systemic regulation. With its multi-pathway, multi-target, and multi-component therapeutic characteristics, TCM can effectively control the metastasis of malignant tumors by regulating the degradation of tumor epithelial mesenchymal transformation (EMT) and extracellular matrix (ECM), anchoring the independent growth of tumor cells and the tumor microenvironment. In this paper, the potential regulatory effects of metabolic reprogramming on the metastasis of malignant tumors were discussed, and the latest research progress of the regulation of metabolic reprogramming by TCM on tumor metastasis was reviewed. At the same time, the key targets of TCM and its bioactive components in the process of tumor metastasis intervention were reviewed. This study aims to provide a more valuable basis and clearer idea for the treatment of malignant tumor metastasis by regulating metabolic reprogramming with TCM.

Sleep is an instinctive behavior alternating awakening state, sleep entails many active processes occurring at the cellular, circuit and organismal levels. The function of sleep is to restore cellular energy, enhance immunity, promote growth and development, consolidate learning and memory to ensure normal life activities. However, with the increasing of social pressure involved in work and life, the incidence of sleep disorders (SD) is increasing year by year. In the short term, sleep disorders lead to impaired memory and attention; in the longer term, it produces neurological dysfunction or even death. There are many ways to directly or indirectly contribute to sleep disorder and keep the hormones, including pharmacological alternative treatments, light therapy and stimulus control therapy. Exercise is also an effective and healthy therapeutic strategy for improving sleep. The intensities, time periods, and different types of exercise have different health benefits for sleep, which can be found through indicators such as sleep quality, sleep efficiency and total sleep time. So it is more and more important to analyze the mechanism and find effective regulation targets during sleep disorder through exercise. Dopamine (DA) is an important neurotransmitter in the nervous system, which not only participates in action initiation, movement regulation and emotion regulation, but also plays a key role in the steady-state remodeling of sleep-awakening state transition. Appreciable evidence shows that sleep disorder on humans and rodents evokes anomalies in the dopaminergic signaling, which are also implicated in the development of psychiatric illnesses such as schizophrenia or substance abuse. Experiments have shown that DA in different neural pathways plays different regulatory roles in sleep behavior, we found that increasing evidence from rodent studies revealed a role for ventral tegmental area DA neurons in regulating sleep-wake patterns. DA signal transduction and neurotransmitter release patterns have complex interactions with behavioral regulation. In addition, experiments have shown that exercise causes changes in DA homeostasis in the brain, which may regulate sleep through different mechanisms, including cAMP response element binding protein signal transduction, changes in the circadian rhythm of biological clock genes, and interactions with endogenous substances such as adenosine, which affect neuronal structure and play a neuroprotective role. This review aims to introduce the regulatory effects of exercise on sleep disorder, especially the regulatory mechanism of DA in this process. The analysis of intracerebral DA signals also requires support from neurophysiological and chemical techniques. Our laboratory has established and developed an in vivo brain neurochemical analysis platform, which provides support for future research on the regulation of sleep-wake cycles by movement. We hope it can provide theoretical reference for the formulation of exercise prescription for clinical sleep disorder and give some advice to the combined intervention of drugs and exercise.

ObjectiveBased on analytic hierarchy process(AHP)-criteria importance through intercriteria correlation(CRITIC) hybrid weighting method, grey relational analysis and backpropagation artificial neural network(BP-ANN), to optimize the water extraction process of Qizhi prescription, so as to provide an experimental basis for optimization of the preparation process of this prescription and the establishment of quality standards. MethodsL9(34) orthogonal test was employed, and the AHP-CRITIC hybrid weighting method was utilized to determine the weight coefficients of the quality fractions of various components, including astragaloside Ⅳ, polygalaxanthone Ⅲ, calycosin-7-O-β-D-glucoside, tenuifolin, and 3,6′-disinapoylsucrose, as well as the dry extract yield. The comprehensive score of each factor level combination in the orthogonal test were calculated as evaluation indicator to select the optimal extraction process parameters. The effects of extraction times, extraction time, and solvent dosage on the aqueous extraction process of the formula were investigated through intuitive analysis, variance analysis, and grey relational analysis. Meanwhile, a BP-ANN model was established to reverse-predict the optimal extraction process parameters of Qizhi prescription, and the optimized process parameters were validated. ResultsThe weight coefficients of the five index components(astragaloside Ⅳ, tenuifolin, calycosin-7-O-β-D-glucoside, polygalaxanthone Ⅲ, and 3,6′-disinapoylsucrose) and dry extract yield were 25.7%, 20.82%, 16.41%, 12.45%, 15.96% and 8.67%, respectively. The optimized extraction process parameters were extracted 3 times with 8, 6, 6 times the amount of water, each time for 1 h. The network prediction results of BP-ANN test samples were consistent with the orthogonal test results, and the mean square error(MSE) of the predicted and measured values of the network was <1%. The water extraction process of Qizhi prescription analyzed and predicted by relevant mathematical models was stable and feasible, which could effectively improve the extraction efficiency of the active ingredients of Astragali Radix and Polygalae Radix, and the average comprehensive score of the validation test was 90.85 with the relative standard deviation(RSD) of 1.55%. ConclusionThis study establishes a water extraction process for compound Qizhi granules, and the optimized extraction process can effectively improve the extraction efficiency of active ingredients, which provides useful references for the optimization of preparation process and the establishment of quality standards for other clinical experience formulas.

" Lijie and yellowish sweating" originates from the chapter on stroke and arthralgia diseases in Synopsis of Golden Chamber. Later generations typically interpret it as yellow fluid oozing from painful joints, a characteristic manifestation of arthralgia. In Western medicine, Lijie corresponds to diseases such as gouty arthritis, with its primary clinical manifestations being redness, swelling, heat, and painful joints, most often without yellow fluid discharge. Therefore, the interpretation of " Lijie and yellowish sweating" contradicts the clinical manifestations often observed in this disease. Thus, this article reinterprets the meaning of " Lijie and yellowish sweating" from the pathogenesis of " sweat exposure to water, as if water harms the heart" , combined with the viewpoints of other medical practitioners. Determining the meaning of " yellowish sweating" is crucial for understanding the pathogenesis of arthralgia and clarifying the relationship between arthralgia and yellowish sweating. ZHANG Zhongjing mentioned arthralgia and " yellowish sweating" together, not to differentiate between the two diseases but to emphasize the common pathogenesis of the two, namely, the cold and dampness injuring the heart, blood, and vessels. This paper proposes a new explanation of " Lijie and yellowish sweating" , which suggests that " yellowish sweating" is not confined to the joints but can be found all over the body. The pathogenesis of " Lijie and yellowish sweating" lies in the insufficiency of the liver and kidney and exogenous water dampness, leading to disharmony between nutrient qi and defensive qi and between yin and yang. Primary treatment should harmonize yingfen and weifen, as well as tonify and replenish the liver and kidney. The clinical selection of medicines can be considered Guizhi Decotion, a type of formula. The pathogenesis of " Lijie and yellowish sweating" is complex, and clinical treatment should be comprehensively considered to achieve the best therapeutic effect.
