Respiratory syncytial virus (RSV) is a ubiquitous respiratory virus that affects individuals of all ages; however, there is a notable lack of targeted treatments. RSV infection is associated with a range of respiratory symptoms, including bronchiolitis and pneumonia. Baicalin (BA) exhibits significant therapeutic effects against RSV infection through mechanisms of viral inhibition and anti-inflammatory action. Nonetheless, the clinical application of BA is constrained by its low solubility and bioavailability. In this study, we prepared BA nanodrugs (BA NDs) with enhanced water solubility utilizing the supramolecular self-assembled strategy, and we further conducted a comparative analysis of this pharmacological activity between free drugs and NDs of BA. Both in vitro and in vivo results demonstrated that BA NDs significantly enhanced the dual effects of viral inhibition and inflammation relief compared to free BA, attributed to prolonged lung retention, improved cellular uptake, and increased targeting affinity. Our study confirms that the nanosizing strategy, a straightforward approach to enhance drug solubility, can also increase biological activity compared to free drugs with the same content, thereby providing a potential ND for RSV treatment. This correlation analysis between the existing forms of drugs and their biological activity offers a novel perspective for research on the active ingredients of traditional Chinese medicine.

ChuanWu (CW), the dried mother root of Aconitum carmichaelii Debx., is a well-known traditional Chinese medicine (TCM) recognized for its potent efficacy but inherent toxicity, primarily due to its alkaloid content. Traditional and modern detoxification methods for CW include proper processing, rational compatibility, and specialized decoction techniques, among which honey-boiled CW is particularly distinctive. However, research on the detoxification mechanism of honey-boiled CW remains limited. This study investigated this mechanism by analyzing alkaloid transformation and supramolecular aggregation. Honey-boiled and water-boiled CW preparations were compared. Ultra-high-performance liquid chromatography-tandem mass spectrometry was used to analyze CW alkaloids, specifically diester alkaloids (DDAs), monoester alkaloids (MDAs), and non-esterified diterpenoid alkaloids (NDAs). Transmission electron microscopy was employed to observe and identify supramolecular aggregates in the honey-boiled CW decoction. In vivo absorption of water-boiled, honey-boiled, and NADES-boiled CW was compared. Median lethal dose (LD50) tests assessed toxicity, including hepatotoxicity and nephrotoxicity. In vitro experiments evaluated the safety, anti-inflammatory, and analgesic effects of CW-medicated serum on RAW264.7 cells, with in vivo validation in mice. Results showed that honey promoted the conversion of highly toxic DDAs to less toxic MDAs and prevented MDAs from hydrolyzing into NDAs. Honey-boiled CW formed approximately 250 nm supramolecular aggregates that encapsulated MDAs, inhibiting their conversion to NDAs. These encapsulated MDAs acted as a stable delivery system with higher bioavailability than free benzoylmesaconine. Subsequent mouse experiments confirmed that honey-boiled CW significantly increased the LD50 of CW while reducing hepatotoxicity and nephrotoxicity. Additionally, honey-boiled CW significantly improved cell safety and enhanced anti-inflammatory and analgesic effects. Our findings reveal that honey-boiled CW exhibits a potent detoxification mechanism by influencing alkaloid transformation and facilitating the formation of supramolecular aggregates. This study lays the groundwork for developing detoxification or synergistic strategies within honey-boiled TCM.

With the increasing incidence of diabetes mellitus in recent years, cardiomyopathy caused by diabetes mellitus has aroused wide concern and this disease is characterized by high insidiousness and high mortality. The early pathological changes of diabetic cardiomyopathy (DCM) are mitochondrial structural disorders and loss of myocardial metabolic flexibility. The turbulence of mitochondrial quality control (MQC) is a key mechanism leading to the accumulation of damaged mitochondria and loss of myocardial metabolic flexibility, which, together with elevated levels of oxidative stress and inflammation, trigger changes in myocardial structure and function. Qi deficiency and stagnation is caused by the loss of healthy Qi, and the dysfunction of Qi transformation results in the accumulation of pathogenic Qi, which further triggers injuries. According to the theory of traditional Chinese medicine (TCM), DCM is rooted in Qi deficiency of the heart, spleen, and kidney. The dysfunction of Qi transformation leads to the generation and lingering of turbidity, stasis, and toxin in the nutrient-blood and vessels, ultimately damaging the heart. Therefore, Qi deficiency and stagnation is the basic pathologic mechanism of DCM. Mitochondria, similar to Qi in substance and function, are one of the microscopic manifestations of Qi. The role of MQC is consistent with the defense function of Qi. In the case of MQC turbulence, mitochondrial structure and function are impaired. As a result, Qi deficiency gradually emerges and triggers pathological changes, which make it difficult to remove the stagnant pathogenic factor and aggravates the MQC turbulence. Ultimately, DCM occurs. Targeting MQC to treat DCM has become the focus of current research, and TCM has the advantages of acting on multiple targets and pathways. According to the pathogenesis of Qi deficiency and stagnation in DCM and the modern medical understanding of MQC, the treatment should follow the principles of invigorating healthy Qi, tonifying deficiency, and regulating Qi movement. This paper aims to provide ideas for formulating prescriptions and clinical references for the TCM treatment of DCM by targeting MQC.

This paper summarized Professor ZHANG Junping's clinical experience in treating coronary heart disease (CHD) combined with hypothyroidism. It is believed that yang deficiency was the root cause of CHD complicated with hypothyroidism, and also the key pathogenesis throughout its development. Accordingly, combined with the different focuses on the lesions in the blood, pulse, heart and spirit, Professor ZHANG took warming yang as the basic rule and summarized the four methods of warming yang for syndrome differentiation and treatment. When spleen-kidney yang deficiency, disturbance of qi transformation, dysfunction of blood transportation as the pathological basis of CHD combined with hypothyroidism, the self-prescribed Butian Formula (补天方) could be used for warming yang and benefiting the kidney, thereby regulating Qi and blood; when the cold and dampness blocked the blood vessels, and turbidity-toxin generated gradually, resulting in heart vessel obstruction, the self-prescribed Huazhuo Changmai Decoction (化浊畅脉汤) could be used to warm yang and dissolve the turbidity so that to unblock the heart vessels; when the structure and function of the heart fail, edema due to yang deficiency with pericardial fluid retention, the self-prescribed Yuxin Baomai Formula (育心保脉方) could be used to warm yang and excret water, and protect the heart; when yang deficiency led to emotional and mental stagnation, and the heart impairment aggravated emotional and mental disorders, which resulted in emotional and mental abnormalities, the self-prescribed Jieyu Anshen Decoction (解郁安神汤) could be used to relieve emotional and mental stagnation, and calm mind.

ObjectiveTo observe the clinical efficacy and relative mechanism of the Modified Wenshen Yixin Formula (温肾益心方加减, MWYF) as an auxiliary treatment of coronary heart disease (CHD) complicated with hypothyroidism of spleen-kidney yang deficiency. MethodsA total of 135 CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency were included and divided into control group (67 cases) and experimental group (68 cases) according to the patients' wishes of herbal medicine administration. The control group was given conventional western medicine, while the treatment group was additionally given MWYF, 1 dose per day; both groups were treated for 8 weeks. The traditional Chinese medicine (TCM) syndrome scores, angina scores, SF-36 scores, thyroid function indicators including thyroid stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3), as well as serum cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), monocyte chemoattractant ligand 2 (CCL2), and tumor necrosis factor-related activator protein (CD40L) levels before and after treatment were compared between the two groups. The dosage and reduction and discontinuation rate of thyroid hormone preparations after treatment were compared between the two groups. The effectiveness regarding TCM syndrome and angina pectoris was evaluated, and the safety was assessed. ResultsBias was adjusted by matching on propensity score, and 102 cases were finally included in the statistical analysis, with 51 cases in each group. The total effective rate regarding TCM syndrome [94.12% (48/51) versus 64.71% (33/51)], the total effective rate regarding angina pectoris [80.39% (41/51) versus 62.75% (32/51)], and the reduction and discontinuation rate of thyroid hormone preparation [39.21% (20/51) versus 5.88% (3/51)] were significantly higher in the experimental group than those in the control group (P<0.05 or P<0.01). After treatment, the total TCM syndrome score, individual scores of major symptoms , the major symptoms score, the secondary symptoms score, angina pectoris score, and TSH level were significantly reduced (P<0.01), while all dimensions of SF-36 scores, T4, T3, and cAMP levels significantly increased in both groups (P<0.05 or P<0.01). The dosage of thyroid hormone preparations and the levels of cGMP, CCL2, and CD40L in the experimental group significantly decreased after treatment (P<0.01). When compared between the two groups after treatment, the total TCM syndrome score, the major symptoms score, the scores of individual major symptom (chest tightness, chest pain, fear of cold, cold limbs, waist and kness soreness and weakness), the secondary symptoms score, angina pectoris score, TSH, cGMP, CCL2, and CD40L levels of the experimental group were significantly lower than those of the control group (P<0.05 or P<0.01), while all dimension scores of SF-36, T4, T3, and cAMP levels were significantly higher (P<0.01). A total of three adverse events occurred during treatment, none of which were judged to be related to the interventions of this study. ConclusionMWYF can significantly ameliorate the TCM syndrome, angina pectoris, quality of life and thyroid function in CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency, and can promote the reduction and disconti-nuation of thyroid hormone preparations. The mechanism may be related to the regulation of cAMP/cGMP balance, the regulation of hypothalamic-pituitary-thyroid metabolic axis and the reduction of immune inflammation.

Guided by the concept of "blood-pulse-heart-spirit", it is believed that stable angina combined with insomnia is caused by disturbance of blood vessels, which leads to loss of nourishment for the heart body and heart spirit, so the core treatment principle is to regulate the blood vessels and calm the mind. At the beginning of the disease, it shows as the liver fails to govern the free flow of qi, and disorders qi and blood; during the progress of the disease, it shows as spleen deficiency and phlegm stagnation, phlegm and blood stasis obstructing the vessels; the central mechanism of the disease shows as disturbance of blood vessels and insufficient heart yin. For the pattern of liver depression and blood stasis, pattern of phlegm and blood stasis blocking the vessels, and pattern of heart yin deficiency, it is recommended to treat by Wuzang Shenning Formula (五脏神宁方) to dredge the liver and regulate the vessels, Banxia Houpo Decoction (半夏厚朴汤) plus Gualou Xiebai Banxia Decoction (瓜蒌薤白半夏汤) to dissolve phlegm and regulate the vessels, and Yunpi Tiaoxin Decoction (运脾调心汤) to nourish the yin and regulate the vessels. Throughout the treatment, pattern differentiation and treatment is accompanied by the method of calming the mind with heavy sedatives and nourishing the blood to calm the mind, so as to achieve the purpose of regulating mind and heart together and treating the body and spirit at the same time.
