		                        			ObjectiveTo explore the possible mechanisms of electroacupuncture at Fengchi (GB 20), Waiguan (TE 5), and Yanglingquan (GB 34) in treating chronic migraine from the perspective of nociceptive sensitization. MethodsForty SPF-grade SD rats were randomly divided into blank group, model group, electroacupuncture group, electroacupuncture + agonist group, and inhibitor group, with 8 rats in each group. Except for the blank group, rats were injected intraperitoneally with nitroglycerin to establish a chronic migraine rat model. After successful modeling, the electroacupuncture group received electroacupuncture at bilateral "Fengchi" (GB 20), "Waiguan" (TE 5), and "Yanglingquan" (GB 34) for 30 minutes each session. The electroacupuncture + agonist group received the same electroacupuncture treatment and additional injection of protein kinase C (PKC) agonist Phorbol 12-myristate 13-acetate (1.0 ng/μl, 25 μl) via the infraorbital foramen. The inhibitor group received PKC inhibitor Chelerythrine Chloride (1.0 ng/μl, 10 μl) via the infraorbital foramen. The blank group, model group, and inhibitor group underwent restraint for 30 minutes without other interventions. All groups were continuously intervened for 5 days. After the intervention, the nociceptive thresholds (mechanical and thermal pain) of the periorbital area and hind paw were measured. The expression levels of transient receptor potential vanillic acid subtype 1 (TRPV1), phosphorylated TRPV1 (p-TRPV1), PKC proteins, Trpv1, Pkc mRNA, and the average fluorescence intensity of transient receptor potential vanillic acid subtype 1 (TRPV1) and PKC in the trigeminal ganglion were detected using Western Blot, real-time fluorescence quantitative PCR, and immunofluorescence methods. ResultsCompared with the blank group, the mechanical and thermal pain thresholds of the periorbital area and hind paw were reduced in the model group, and the protein levels of TRPV1, PKC, p-TRPV1, as well as the mRNA expression of Trpv1 and Pkc, and the average fluorescence intensity of TRPV1 and PKC in the trigeminal ganglion significantly increased (P<0.05 or P<0.01). Compared with the model group, the electroacupuncture group exhibited increased mechanical and thermal pain thresholds in the periorbital and hind paw areas, and decreased protein levels of TRPV1, PKC, p-TRPV1, mRNA expression of Trpv1 and Pkc, and average fluorescence intensity of TRPV1. In the electroacupuncture + agonist group, the average fluorescence intensity of TRPV1 in the trigeminal ganglion decreased. The inhibitor group exhibited increased mechanical pain thresholds in the periorbital area and thermal pain thresholds in the hind paw, along with decreased protein levels of TRPV1, PKC, p-TRPV1, and the average fluorescence intensity of TRPV1 and PKC (P<0.05 or P<0.01). Compared with the electroacupuncture group, the electroacupuncture + agonist group showed an increase in the protein levels of TRPV1, PKC, p-TRPV1, and the mRNA expression of Trpv1 (P<0.05 or P<0.01). ConclusionElectroacupuncture at the "Fengchi" (GB 20), "Waiguan" (TE 5), and "Yanglingquan" (GB 34) acupoints can increase the mechanical and thermal pain thresholds in chronic migraine rats and alleviate nociceptive sensitization. The mechanism may be related to the inhibition of PKC/TRPV1 pathway.

		                        			Traditional Chinese medicines (TCMs) possess a rich historical background, unique theoretical framework, remarkable therapeutic efficacy, and abundant resources. However, the modernization and internationalization of TCMs have faced significant obstacles due to their diverse ingredients and unknown mechanisms. To gain deeper insights into the phytochemicals and ensure the quality control of TCMs, there is an urgent need to enhance analytical techniques. Currently, two-dimensional (2D) chromatography, which incorporates two independent separation mechanisms, demonstrates superior separation capabilities compared to the traditional one-dimensional (1D) separation system when analyzing TCMs samples. Over the past decade, new techniques have been continuously developed to gain actionable insights from complex samples. This review presents the recent advancements in the application of multidimensional chromatography for the quality evaluation of TCMs, encompassing 2D-gas chromatography (GC), 2D-liquid chromatography (LC), as well as emerging three-dimensional (3D)-GC, 3D-LC, and their associated data-processing approaches. These studies highlight the promising potential of multidimensional chromatographic separation for future phytochemical analysis. Nevertheless, the increased separation capability has resulted in higher-order data sets and greater demands for data-processing tools. Considering that multidimensional chromatography is still a relatively nascent research field, further hardware enhancements and the implementation of chemometric methods are necessary to foster its robust development.

		                        			ObjectiveTo investigate the possible mechanism of electroacupuncture at Fengchi (GB 20), Yanglingquan (GB 34) and Waiguan (TE 5) for acute migraine attacks by peroxisome proliferator-activated receptor γ/ nuclear transcription factor-κB pathway in the trigeminal neurovascular system. MethodsForty SD rats were randomly divided into blank group, model group, electroacupuncture group, electroacupuncture plus inhibitor group, and agonist group, 8 rats in each group. Except for the blank group, rats were injected with inflammation decoction intracranial catheter to establish rat models of acute migraine. Thirty minutes after modelling, the electroacupuncture group was given 0.9% NaCl solution by intraperitoneal injection and then electroacupuncture at "Fengchi" (GB 20), "Yanglingquan" (GB 34), and "Waiguan" (TE 5) for 30 mins; the electroacupuncture plus inhibitor group was given PPARγ inhibitor T0070907 (1.5 mg/kg) and eclectroacupuncture as the above for 30 mins; the agonist group was given PPARγ inhibitor pioglitazone hydrochloride (10 mg/kg) for 30 mins. Rats in the blank group and the model group were injected intraperitoneally with 0.9% NaCl solution and then bound and restrained for 30 mins. Behavioural scores were evaluated before modelling, 30 mins after modelling (pre-intervention) and post-intervention; after the last behavioural test, PPARγ, NF-κB p65 mRNA content in rat dura mater was detected by real-time fluorescence quantitative PCR; protein expression of PPARγ, NF-κB p65, interleukin 6 (IL-6), tumour necrosis factor α (TNF-α) in spinal trigeminal nucleus of rats was detected by protein blotting; immunofluorescence double-labelling method was used to detect the fluorescence intensity of PPARγ, NF-κB p65 in spinal trigeminal nucleus of rats. ResultsCompared with the blank group at the same time, the behavioural scores of rats in the remaining groups increased after modelling and after intervention (P<0.01). Compared with the model group at the same time, the beha-vioural scores of rats in the electroacupuncture group, electroacupuncture plus inhibitor group, and agonist group decreased after the intervention (P<0.01). Compared with the electroacupuncture group at the same time, beha-vioural scores reduced in the agonist group and elevated in the electroacupuncture plus inhibitor group after intervention (P<0.01). Compared with the blank group, expression of PPARγ and NF-κB p65 mRNA elevated in the dura mater of rats in the model group, and expression of PPARγ, NF-κB p65, IL-6, and TNF-α protein enhanced in spinal trigeminal nucleus, and the fluorescence intensity of PPARγ and NF-κB p65 enhanced (P<0.01). Compared with the model group, PPARγ mRNA expression in dura mater elevated and NF-κB p65 mRNA expression reduced in each intervention group, PPARγ protein expression in spinal trigeminal nucleus enhanced, and NF-κB p65, IL-6, and TNF-α protein expression weakened; in the electroacupuncture group and the agonist group, PPARγ fluorescence intensity enhanced, and the fluorescence intensity of NF-κB p65 weakened in each intervention group (P<0.05 or P<0.01). Compared with the electroacupuncture group, in the electroacupuncture plus inhibitor group, PPARγ mRNA, protein expression and fluorescence intensity reduced, NF-κB p65 mRNA, protein expression and fluorescence intensity elevated, and IL-6 and TNF-α protein expression enhanced; in the agonist group, PPARγ mRNA and protein expression elevated, NF-κB p65 mRNA and protein expression reduced, and IL-6 and TNF-α protein expression decreased (P<0.05 or P<0.01). ConclusionElectroacupuncture at "Fengchi" (GB 20), "Yanglingquan" (GB 34) and "Waiguan" (TE 5) can can reduce the symptoms of acute migraine attacks in rats, and its mechanism may be related to the up-regulation of PPARγ expression and the reduction of NF-κB expression, thus inhibiting the neurogenic inflammatory response.

		                        			 Amorphous solid dispersion (ASD) is one of the most effective formulation approaches to enhance the water solubility and oral bioavailability of poorly water-soluble drugs. However, maintenance of physical stability of amorphous drug is one of the main challenges in the development of ASD. Crystallization is a process of nucleation and crystal growth. The nucleation is the key factor that influences the physical stability of the ASD. However, a theoretical framework to describe the way to inhibit the nucleation of amorphous drug is not yet available. We reviewed the methods and theories of nucleation for amorphous drug. Meanwhile, we also summarized the research progress on the mechanism of additives influence on nucleation and environmental factors on nucleation. This review aims to enhance the better understanding mechanism of nucleation of amorphous drug and controlling over the crystal nucleation during the ASD formulation development.
