Chinese medicinal materials serve as the material foundation of traditional Chinese medicine (TCM) culture. The sustainable development of Chinese medicinal material resources is a focal point in the modernization of TCM. With the increasing scarcity of Chinese medicinal material resources, the expansion of new Chinese medicinal material resources has become a crucial means for the sustainable utilization of these resources. New Chinese medicinal material resources refer to natural resources that have been newly discovered or developed, possessing potential medicinal value or healthcare functions, which fall outside the traditional application scope of herbal medicines. These resources have not yet been widely recognized or applied within the framework of traditional TCM theory. They specifically include artificial substitutes for endangered medicinal materials, new medicinal parts of medicinal plants, medicinal materials with expanded clinical applications, and foreign medicinal resources. The rational compatability and formulation of new Chinese medicinal material resources are essential pathways for integrating them into the TCM system. Due to the weak foundational research on new Chinese medicinal material resources in China, the characteristics of these resources that align with the TCM theory are not yet fully understood, posing numerous constraints on formulating prescriptions based on the traditional compatibility principles of TCM. This paper integrates the traditional formulation theory of TCM with modern data integration methods, proposing four formulation models for new TCM resources: synergistic compatibility, substitutive compatibility, symptom-based compatibility, and efficacy semantic compatibility. These models provide new insights for the application of new Chinese medicinal material resources, not only facilitating their rational use in clinical practice but also offering theoretical support for the development and compatibility research of these resources.

ObjectiveTo investigate the mechanism of Forsythiae Fructus-Lonicerae Japonicae Flos(FF) in the treatment of acute lung injury(ALI) by investigating the effects of FF on serum metabolomics of rats with ALI. MethodsThirty male SD rats were acclimated for 1 week, and 6 rats were randomly selected as the blank group. The other 24 rats were injected with lipopolysaccharide(LPS) solution by tracheal drip to establish an ALI model. After successful model establishment, the rats were randomly divided into the model group, the FF low-dose group(3.0 g·kg-1), the FF high-dose group(6.0 g·kg-1), and the dexamethasone group(5 mg·kg-1), with six rats in each group. The FF low- and high-dose groups and the dexamethasone group were received daily oral administration of the corresponding drug solution, and the blank group and the model group were gavaged with an equal amount of saline, treatment was administered continuously for 3 d. The pathological conditions of rat lung tissues were evaluated by hematoxylin-eosin(HE) staining, wet/dry mass ratio(W/D) of the lung tissues, and protein concentration in rat bronchoalveolar lavage fluid(BALF). Metabolomic analysis of rat serum was performed by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS), combined with multivariate statistical analysis, the potential biomarkers of FF in treating ALI were screened by variable importance in the projection(VIP) value>1, P<0.05 from t-test, and log2fold change(FC)>1 or log2FC<-1. Kyoto Encyclopedia of Genes and Genomes(KEGG) database combined with MetaboAnalyst were used for pathway analysis of the screened differential metabolites. The protein expression levels of sphingosine-1-phosphate(S1P), phosphatidylinositol 3-kinase(PI3K), protein kinase B1(Akt1), and phosphorylated Akt1(p-Akt1) were examined by Western bolt. The expression levels of interleukin(IL)-6, IL-1β, and tumor necrosis factor(TNF)-α in BALF were detected by enzyme-linked immunosorbent assay(ELISA). ResultsCompared with the blank group, rats in the model group showed ALI pathological features such as alveolar lumen dilatation, interstitial hemorrhage and massive inflammatory cell infiltration, and the protein concentration in BALF and W/D of the lung tissues were significantly elevated(P<0.01). Compared with the model group, the low- and high-dose groups of FF as well as the dexamethasone group exhibited reduced pulmonary bronchial hemorrhage in rats, and the protein concentration in BALF and W/D were significantly decreased(P<0.05), and the lung injury was significantly alleviated. Analysis of rat serum metabolomics revealed that FF downregulated 38 biomarkers. Pathway enrichment analysis showed that FF primarily exerted therapeutic effects through 7 key metabolic pathways, including arginine biosynthesis, sphingomyelin metabolism, alanine, aspartate and glutamate metabolism, taurine and hypotaurine metabolism, α-linolenic acid metabolism, niacin and nicotinamide metabolism, and retinol metabolism. The results of Western bolt and ELISA showed that, compared with the blank group, the model group exhibited significantly elevated expression levels of S1P, PI3K, Akt1 and p-Akt1 proteins in the lung tissues, as well as increased expression levels of IL-6, IL-1β and TNF-α in BALF(P<0.01). Compared with the model group, the expression levels of the aforementioned indicators were significantly downregulated in the low- and high-dose FF groups as well as the dexamethasone group(P<0.05, P<0.01). ConclusionFF may play a role in ALI by regulating amino acid metabolism and lipid metabolism, and its mechanism may be related to the inhibition of S1P/PI3K/Akt1 signaling pathway to attenuate the inflammatory response caused by ALI.

The KCNQ potassium channels play a crucial role in modulating neural excitability, and their dysfunction is closely associated with epileptic disorders. While variants in KCNQ2 have been extensively studied, KCNQ3-related disorders have rarely been reported. With advances in next-generation sequencing technologies, an increasing number of cases of KCNQ3-related disorders have been identified. However, the correlation between genotype and phenotype remains poorly understood. In this study, we established a variant library consisting of 24 missense mutations in KCNQ3 and introduced these mutations into three different template types: KCNQ3, KCNQ3-A315T (Q3*), and KCNQ3-KCNQ2 tandem (Q3-Q2). We then analyzed the effects of these mutations on the KCNQ3 channel function using patch-clamp recording. The most informative parameter across all three backgrounds was the current density of the mutant channels. The current density patterns in the Q3* and Q3-Q2 backgrounds were similar, with most mutations resulting in an almost complete loss of function (LOF), they were concentrated in the pore-forming domain of KCNQ3. In contrast, mutations in the voltage-sensing domain or C-terminus did not show significant differences from the wild-type channel. Interestingly, these LOF mutations were typically associated with self-limited familial neonatal epilepsy, while neurodevelopmental disorders (NDD) were more closely associated with mutations that did not significantly differ from the wild-type. V1/2, another important parameter of the electrophysiological properties, could not be accurately determined in the majority of KCNQ3 mutations due to its nearly complete LOF in the Q3* and Q3-Q2 backgrounds. Intriguingly, the V1/2 of functional mutations were primarily leftward shifted, indicating a gain-of-function (GOF) effect, which was typically associated with NDD. In addition to previously reported mutations, we identified G553R as a novel GOF mutation. In the co-transfection background, parameters such as V1/2 could be determined, but the dysfunctional effects of these mutations were mitigated by the co-expression of wild-type KCNQ3 and KCNQ2 subunits, resulting in no significant differences between most mutations and the wild-type channel. Furthermore, we applied KCNQ modulators to reverse the electrophysiological abnormalities caused by KCNQ3 variants. The LOF mutations were reversed by the application of Pynegabine (HN37), a KCNQ opener, while the GOF mutation responded well to Amitriptyline (AMI), a KCNQ inhibitor. These findings provide essential insights into the pathogenic mechanisms underlying KCNQ3-related disorders and may inform clinical decision-making.

Objective:To observe the effects of acupuncture and moxibustion on ubiquitin-like containing PHD and RING finger domains 1(UHRF1)and DNA methyltransferase 1(DNMT1)in ectopic endometrium of rats with endometriosis(EMS). Methods:Forty Sprague-Dawley rats were randomly divided into a sham operation group with 10 rats and a model-building group with 30 rats according to body mass.EMS rat models were established in the model-building group and then were divided into a model group,an acupuncture and moxibustion group,and a progesterone group,with 10 rats in each group.All rats were fixed by a fixator.The sham operation group and the model group were given normal saline by gavage.The acupuncture and moxibustion group received acupuncture at Xuehai(SP10)and Sanyinjiao(SP6),moxibustion at Guanyuan(CV4),and gavage of normal saline.The progesterone group was given the mixed liquid made of dydrogesterone and normal saline by gavage.After 28 d of treatments,the three diameters(length,width,and height)of EMS rats'ectopic cysts were measured,the cyst volumes were calculated,the volumes before intervention were subtracted,and the difference values were used to evaluate the growth of ectopic cysts.UHRF1 and DNMT1 mRNA and protein levels in normal endometrium,eutopic endometrium,and ectopic endometrium were detected by real-time polymerase chain reaction and immunohistochemistry. Results:There was no significant difference in the ectopic cyst volume difference between the acupuncture and moxibustion group and the progesterone group(P>0.05),but they were smaller than that of the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the ectopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of DNMT1 mRNA and UHRF1 protein in the eutopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of UHRF1 mRNA and protein and the level of DNMT1 protein in the ectopic endometrium of the acupuncture and moxibustion group were higher than those in the model group(P<0.05),and the level of UHRF1 mRNA was higher than that in the progesterone group(P<0.05).The level of DNMT1 mRNA in the eutopic endometrium of the acupuncture and moxibustion group was higher than that in the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the acupuncture and moxibustion group were insignificantly different from those in the normal endometrium(P>0.05). Conclusion:Acupuncture and moxibustion may up-regulate the levels of UHRF1 mRNA and UHRF1 and DNMT1 proteins in the ectopic endometrium to the normal level so as to reduce the volume of ectopic cysts and cure EMS in rats.

Objective:To investigate the protective effects of an anti-inflammatory mixture on acute lung injury (ALI) induced by sepsis in rats, as well as its possible mechanisms.Methods:A total of 40 Sprague-Dawley (SD) rats were randomly divided into the sham group, septic ALI model group (model group), 3-methyladenine (3-MA) control group, and anti-inflammatory mixture pretreatment group, with 10 rats in each group. Cecal ligation and perforation (CLP) was performed to reproduce a septic ALI model. The rats in the sham group only underwent opening and closing the abdomen without perforation and ligation. Both groups were given saline gavage and intraperitoneal injection for 3 consecutive days before surgery. The 3-MA control group was given intraperitoneal injection of saline and autophagy inhibitor 3-MA 15 mg/kg for 3 consecutive days before modeling. The anti-inflammatory mixture pretreatment group was given 8.8 mL/kg of anti-inflammatory mixture by gavage [the composition of anti-inflammatory mixture: rhubarb 15 g (after the next), coptis chinensis 15 g, baical skullcap root 12 g, magnoliae cortex 12 g, dahurian patrinia herb 30 g] and saline intraperitoneal injection for 3 consecutive days before modeling. The rats in each group were anesthetized 24 hours after surgery and died due to abdominal aortic blood collection. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum inflammatory cytokines interleukins (IL-1β and IL-6). Lung tissue was taken and then the bronchoalveolar lavage fluid (BALF) was collected, and the levels of IL-1β and IL-6 were detected by ELISA. Lung wet/dry weight (W/D) ratio was measured. After hematoxylin-eosin (HE) staining, the histopathological changes of the lungs were observed under light microscopy. Western blotting was used to detect the expression of autophagy markers microtubule-associated protein 1 light chain 3-Ⅱ/Ⅰ (LC3-Ⅱ/Ⅰ) and Beclin-1 protein in lung tissue. Autophagosomes in lung tissue were observed with transmission electron microscopy.Results:Compared with the sham group, the rats in the model group exhibited severe destruction of lung tissue structure, with significant infiltration of inflammatory cells, the lung W/D ratio and the levels of IL-1β and IL-6 in serum and BALF were significantly increased, the expressions of LC3-Ⅱ/Ⅰ and Beclin-1 protein were down-regulated, the autophagosomes were more. The rats in the 3-MA control group exhibited more severe lung tissue injury as compared with the model group, the lung W/D ratio and the levels of inflammatory cytokines in serum and BALF were further increased, the expressions of LC3-Ⅱ/Ⅰ and Beclin-1 protein still showed a decrease tendency as compared with the sham group, and the autophagosomes were less than that in the model group. Compared with the model group, the anti-inflammatory mixture pretreatment group showed milder lung tissue injury with a minimal amount of inflammatory cell infiltration, the lung W/D ratio was significantly reduced (7.07±1.02 vs. 11.33±1.85, P < 0.05), the levels of IL-1β and IL-6 in both serum and BALF were significantly decreased [IL-1β (ng/L): 26.04±3.86 vs. 40.83±5.46 in serum, 17.75±2.02 vs. 26.86±4.32 in BALF; IL-6 (ng/L): 91.28±10.15 vs. 129.44±13.05 in serum, 76.06±7.51 vs. 120.91±7.47 in BALF, all P < 0.05], and the ratio of LC3-Ⅱ/Ⅰ and Beclin-1 protein expression were significantly increased [LC3-Ⅱ/Ⅰ ratio: 1.23±0.02 vs. 0.60±0.02, Beclin-1 protein (Beclin-1/GAPDH): 2.37±0.33 vs. 0.62±0.05, both P < 0.05]. Furthermore, an increase in the number of autophagosomes was observed. Conclusion:The anti-inflammatory mixture improves lung injury in rats with sepsis induced by CLP and reduce inflammation levels, potentially through upregulation of Beclin-1-mediated autophagy.
