ObjectiveTo comprehensively identify the O-methyltransferase (OMT) genes in Carthamus tinctorius and explore the key OMTs that can catalyze the methylation of flavonoids, providing a basis for understanding the molecular formation mechanism of the structural diversity of flavonoids in C. tinctorius. MethodsThe hidden Markov model was used to systematically identify the type Ⅰ OMTs from the high-quality genome data of C. tinctorius. A suite of bioinformatics tools was employed to systematically analyze the physicochemical properties, gene structure, conserved motifs, chromosomal localization, gene replication events, and collinearity of the identified genes. The target gene was heterologously expressed through the prokaryotic expression system of E. coli, and the protein function was verified by in vitro enzymatic reactions. ResultsA total of 31 type Ⅰ OMTs were identified. CtFOMT1 was successfully cloned and expressed in a soluble form in Escherichia coli. The recombinant protein was purified via Ni2+ affinity chromatography to obtain a high-concentration preparation. In vitro enzymatic assays demonstrated that CtFOMT1 utilized S-adenosylmethionine as the methyl donor to catalyze the methylation of the 4′-OH of naringenin, resulting in the production of isosakuranetin. A similar process occurred with the 4′-OH of luteolin, leading to the formation of diosmetin. Subsequent methylation of the 3′-OH group of diosmetin generated 4′-methylchrysoeriol. ConclusionCtFOMT1 can catalyze the methylation of 4′-/3′-OH in the flavonoid skeleton. It is hypothesized that CtFOMT1 may play a role in the biosynthesis of various 4′-/3′-oxymethyl flavonoids in C. tinctorius.

By consulting herbal texts, medical records, formula collections, and other relevant literature from various historical periods, as well as modern and contemporary research materials, different aspects of the historical evolution of Zijingpi, including its name, origin, scientific name verification, medicinal part, genuine producing areas, harvesting, processing, and preparation, properties and flavors, and primary indications, were systematically reviewed and verified, providing a basis for the development of famous classical formula preparations containing this medicinal material. According to the textual research, Cercis chinensis was first recorded under the name "Zijingmu" in the Rihuazi Bencao from the Five Dynasties period. From the Song Dynasty to the Qing Dynasty, it was known by various names such as "Zijing", "Zijingpi", and "Zijingmupi". In modern and contemporary times, it has been officially named "Zijingpi", with aliases such as "Mantiaohong", "Zihuashu", and "Qingminghua". Historically, the mainstream source of Zijingpi was the dried bark of Cercis chinensis Bunge, a species of the legume family. However, there were also instances of confusion with the Lythraceae plant Lagerstroemia indica L. The producing areas of Zijingpi have no special geographical limitation, and the plant is currently distributed throughout most parts of China. There were no special requirements for harvesting time in ancient times, while modern records indicate harvesting time in spring, summer, and autumn. Ancient processing methods were rarely recorded, with only mentions of stir-frying Zijingpi. Modern practice mostly uses the raw material medicinally. Modern standards prefer it to be "dry, long strips, and thick". The functions of Zijingpi, mainly to promote blood circulation, relieve strangury, and detoxify, have remained consistent from ancient to modern times. Based on the textual research findings, it is recommended that when developing and exploiting the famous classical formulas containing Zijingpi, the bark of C. chinensis should be selected as the source. The processing method should be chosen according to the formula requirements, and if no specific requirements are indicated, it is suggested to use the raw material medicinally.

OBJECTIVE To provide a reference for clinical pharmacists to participate in the treatment of rare and complex cases of CTLA-4 haploid deficiency combined with severe malnutrition. METHODS The clinical pharmacist participated in the diagnosis and treatment of a complex case of CTLA-4 haploid deficiency with severe malnutrition, type 1 diabetes, blood coagulation abnormalities with gastrointestinal bleeding and virus infection, assisted the doctor to develop an individualized parenteral nutrition program, and dynamically adjusted the ratio of glucose and insulin (from 3.9∶1 to 15.6∶1). When patient had severe coagulation abnormalities and gastrointestinal bleeding, the clinical pharmacist recommended discontinuing fat emulsion and switching to glucose amino acid dual energy supply; when the patient had a high fever accompanied by a sudden drop in platelets, the clinical pharmacist recommended to improve the second-generation sequencing of plasma metagenomics. Based on positive results for both EB virus and cytomegalovirus, the clinical pharmacist recommended to discontinue meropenem and switch to ganciclovir for antiviral treatment; when the patient experienced systemic itching and mental excitement, the clinical pharmacist quickly diagnosed as an adverse reaction of ganciclovir and recommended to switch to acyclovir for antiviral treatment. The clinical pharmacist simultaneously carried out parenteral nutrition medication education, and standardized infusion speed, and continuously monitored bleeding-related indicators. RESULTS The physician adopted the advice of the clinical pharmacist. After comprehensive intervention, the patient’s body temperature returned to normal, gastrointestinal bleeding stopped, coagulation indicators significantly improved, blood sugar control reached the standard, and the condition improved and the patient was discharged. CONCLUSIONS Clinical pharmacists rely on comprehensive pharmaceutical services to balance the benefits and risks of treatment for rare and complex cases. They play a key role in individualized nutrition planning, refined blood glucose control, infection identification and anti-infection optimization, and identification and treatment of adverse drug reactions to ensure patient medication safety and efficacy.

ObjectiveTo analyze the volatile components in raw Coptidis Rhizoma, Euodiae Fructus juice-processed Coptidis Rhizoma (Yuhuanglian), and the processing adjuvant Euodiae Fructus juice, identify marker volatile components in the processed product, and elucidate the material basis changes during the processing with Euodiae Fructus juice. MethodsHeadspace solid-phase microextraction coupled with gas chromatography-quadrupole-time-of-flight mass spectrometry (HS-SPME-GC-Q-TOF-MS) was employed to analyze the volatile components in raw Coptidis Rhizoma, Yuhuanglian, and Euodiae Fructus juice. Chemometric analysis was performed to compare volatile components among samples and screen the marker components. Finally, the relative odor activity value (ROAV) was calculated to investigate odor characteristics. ResultsA total of 127 components were detected, with 27, 75, 84 volatile components identified in Euodiae Fructus juice, raw Coptidis Rhizoma, and Yuhuanglian, respectively. Processing with Euodiae Fructus juice significantly increased the number and content of volatile components. Chemometric analysis revealed significant changes in volatile components among the three sample types, allowing clear discrimination. After processing, 39 components such as methyl octanoate and allyl propionate were introduced, while 34 components including furfural and hexanoic acid increased in content, and 11 components including butyric acid and octanal decreased. Additionally, eight components, including zingiberene, 6-methyl-6-hepten-2-one, and 5-methyl-2-hexanone, were screened as marker components of Yuhuanglian. Moreover, processing enhanced the ROAV values of 2,5-dimethylpyrazine (roasted, nutty, coffee-like aroma), 3-ethylphenol, and guaiacol (smoky, woody aroma). Additionally, it incorporated 1-hepten-3-one from Euodiae Fructus juice and the newly generated 1-hexen-3-one, contributing mushroom and cucumber-like odors. The sensory profile of Yuhuanglian integrated nutty, roasted, smoky, and woody notes with the citrus and fruity aroma originally contributed by octanal. ConclusionThe processing with Euodiae Fructus juice introduced components from adjuvant, significantly altering the volatile component profile and enhancing the sensory odor characteristics of Yuhuanglian. This study provides a valuable reference for exploring the material basis of volatile components and establishing processing specifications for Yuhuanglian.

The thought of medicine and food homology and substances with both edible and medicinal values are an important part of China's excellent traditional culture and medicine treasure, playing an important role in human diet and health maintenance for thousands of years. Substances with both edible and medicinal values are a standardized name governed by existing regulations, and many substances with both edible and medicinal values in the list lack important information such as original plants and edible and medicinal parts. Some substances change as the relevant regulations change, which confuses the use and regulation. According to the definition and inclusion conditions of substances with both edible and medicinal values in the Regulation of Substances with Both Edible and Medicinal Values Catalogue, this paper comprehensively reviewed the first batch of 87 substances with both edible and medicinal values published in 2002 by collecting information and investigating the practical application. Some substances supplemented, deleted, and revised were analyzed and discussed, and a complete revised list was compiled, encompassing a total of 90 substances, which were when combined with the 19 substances of the last three batches(published in 2019, 2023, and 2024), amounted to a total of 109 substances. In addition, the substances not currently in the published list but have both edible and medicinal values according to the latest definition were summarized, which revealed at least 27 other substances. Therefore, there were at least 136 substances with both edible and medicinal values. Additionally, the potential substances that could be included in the list of substances with edible and medicinal values were prospected, providing a focus for future expansion of the list. This paper systematically reviewed and revised the list of substances with both edible and medicinal values to lay a foundation for the regulatory authorities to revise the catalog of these substances and provide basic information for promoting the new quality productive forces in the health field and boosting the orderly and rapid development of the big health industry.

Ecological cultivation is an important way for the sustainable production of traditional Chinese medicine in the context of the carbon peaking and carbon neutrality goals. Facility cultivation and simulative habitat cultivation modes have been developed and applied to develop the endangered Dendrobium huoshanense on the basis of protection. However, the differences in the greenhouse gas emissions and global warming potential of these cultivation modes remain unexplored, which limits the accurate assessment of carbon-friendly ecological cultivation modes of D. huoshanense. Greenhouse gas emission flux monitoring based on the static chamber method provides an effective way to solve this problem. Therefore, this study conducted a field experiment in the facility cultivation and simulative habitat cultivation modes at a D. huoshanense cultivation base in Dabie Mountains, Anhui Province. From April 2023 to March 2024, samples of greenhouse gases were collected every month, and the concentrations of CO_2, CH_4, and N_2O of the samples were then detected by gas chromatography. The greenhouse gas emission fluxes, cumulative emissions, and global warming potential were further calculated, and the following results were obtained.(1)The two cultivation modes of D. huoshanense showed significant differences in greenhouse gas emission fluxes, especially the CO_2 emission flux, with a pattern of facility cultivation>simulative habitat cultivation [(35.60±11.70)mg·m~(-2)·h~(-1) vs(2.10±4.59)mg·m~(-2)·h~(-1)].(2) The annual cumulative CO_2 emission flux in the case of facility cultivation was significantly higher than that of simulative habitat cultivation[(3 077.00±842.00)kg·hm~(-2) vs(221.00±332.00)kg·hm~(-2)], while no significant difference was found in annual cumulative CH_4 and N_2O emission fluxes.(3) The facility cultivation mode had a significantly higher global warming potential than the simulative habitat cultivation mode [(3 053.00±847.00)kg·hm~(-2) vs(196.00±362.00)kg·hm~(-2)]. Overall, the simulative habitat cultivation of D. huoshanense has obvious carbon-friendly characteristics compared with facility cultivation, which is in line with the concept of ecological cultivation of medicinal plants. This study is of great reference significance for the implementation and promotion of the ecological cultivation mode of D. huoshanense under carbon peaking and carbon neutrality goals.

Hypertension, a common risk factor for cardiovascular diseases, has aroused global concern. As breakthroughs have been achieved in the traditional Chinese medicine(TCM) and western medicine theories related to the heart and brain, top international journals such as Science pay increasing attention to the functional interaction between the heart and brain in modern medicine, known as the "heart-brain" axis, also referred to as the "cardiovascular-brain" circuit. The heart and brain interact and influence each other through the "heart-brain" axis. Increasing evidence suggests that the inflammation-regulated "heart-brain" axis plays a crucial role in the occurrence and development of hypertension, offering new insights for the treatment of cardiovascular diseases. In TCM, there is a connection between the heart and brain by the sharing of blood essence, interconnected blood vessels, and shared governance over the mind. Diseases of the heart and brain share common pathological and physiological foundations, similar risk factors, and TCM pathogeneses, which form the basis for simultaneous treatment of heart and brain diseases in TCM. The principle of simultaneous treatment of the heart and brain diseases aligns with the theory of "heart-brain" axis. Modern research has found that the heart and brain are the main target organs of hypertension. Long-term high blood pressure can easily cause structural changes, mainly characterized by left ventricular hypertrophy and dilation, leading to hypertensive heart disease. Hypertension can change the structure, blood supply, and function of the brain, being closely related to cerebral atherosclerosis, cerebral infarction, cerebral hemorrhage, cognitive dysfunction, dementia and other brain diseases. TCM treatment of hypertension has a long history. According to the pathogenesis(Yang hyperactivity and blood stasis) of hypertension, the team has developed the core treatment principle of subduing Yang and activating blood. Through extensive clinical exploration and experimental research, the team has developed an effective prescription called Tianxiong Granules. This prescription has shown definite efficacy in stabilizing blood pressure, ameliorating clinical symptoms, and reducing target organ damage. The protective effects of Tianxiong Granules on the heart and brain are reflected in aspects such as symptoms related to the heart and brain, pharmacological effects on ventricular hypertrophy, and brain protection. The preliminary research by the team found that Tianxiong Granules might treat hypertension by inhibiting sympathetic nerve excitation and renin-angiotensin-aldosterone system(RAAS) and targeting mitochondrial autophagy to regulate the activation of the NOD-like receptor family pyrin domain containing 3(NLRP3) inflammasome. The activation of the NLRP3 inflammasome mediates pyroptosis, which is a key mechanism of hypertension. Next, the team will construct the adeno-associated viruses with downregulated NLRP3 expression via adenoviral vectors and use viral tracing technology, left stellate ganglionectomy, and a cardiac denervation model to reveal the mechanism of Tianxiong Granules in regulating the heart-brain interaction in hypertensive rats, from both in vivo and in vitro perspectives. In summary, exploring clinical treatment strategies for hypertension from both heart and brain based on the "heart-brain" axis is likely to be a new direction for the development of drugs for hypertension and offers a new target and basis for intervention in hypertension.
