Since the introduction of acupuncture in the West,the primary focus of interest has been on its analgesic effects. in the 19 90 s,several research groups began to investigate the effects of acupuncture on biliary system m otility. Here,we have reviewed all the recently published articles about the effects of acupuncture and acupuncture-like stimulation on sphincter of Oddi( SO) and gallbladder m *** used for these studies were auricular liver-gall point,Yanglinguan( Gb3 4) ,Qim en( L R14 ) and Riyue( Gb2 4) . Acupuncture and acupuncture-like stimulation at LR14 ,Gb2 4,which are located in the trunk,showed an increased SO *** contrast,acupuncture at Gb3 4in lower lim b and TENS at the hand showed a decreased SO contraction.A lso,auricular liver-gall point stimulation caused a marked contraction of the gallbladder. These results agree with Sato’ s report that gastric motility was inhibited by acupuncture applied to the abdom en and lower chest region,but was often excited when the lim bs were stimulated. The results of two articles show that acupuncture stim ulation decreased SO basal pressure and was accompanied by a significant increase in cholecystokinin ( CCK) and vasoactive intestinal ***,it was proposed that the effect of acupuncture on biliary system motility is that acupuncture first stim ulates the autonom ic or central nervous system,thereby controlling the release of the hormones that influence the SO and gall *** conclusion,acupuncture stim ulation of various acupoints results in inhibition or excitation of biliary system m *** response of SO and gall bladder motility can be mediated by neurohorm onal m echanisms,including CCK release.

Objective: To take baihui (GV20) and Fengchi (Gb20) targeting inflammatory response to regulate migraine as an example to describe a new method for studying the mechanism of stimulating ***: The target information of baihui (GV20) and Fengchi (Gb20) was retrieved， and after intersection with migraine， Kyoto Encyclopedia of Genes and Genomes (KEGG)， Reactome， and UniProt Keywords were used for functional enrichment. After selecting the main pathway， rats were selected and nitroglycerin was used for modeling， and the behavioral scores， inflammatory factors， heme oxygenase 1 (HMOX1)， protein kinase b (AKT1)， signal transducer and activator of transcription 3 (STAT3)， phosphorylated extracellular signal-regulated kinase 1/2 (P-ERK1/ERK2) and other states of the rats in the acupuncture， twisting， and electroacupuncture groups were ***: A total of 135 baihui (GV20) targets and 27 Fengchi (Gb20) targets were collected. A total of 73 target information were obtained after the intersection of these targets in migraine. These 73 targets have three main pathways: hypoxia-inducible factor 1 (HiF-1) signaling pathway， signaling by interleukins and inflammatory response. The main targets in the pathway were verified and found that interleukin-1 beta (iL-1β)， interleukin-6 (iL-6)， tumor necrosis factor-alpha (TNF-α) and HMOX1， AKT1， STAT3， P-ERK1/ERK2 can be regulated by baihui (GV20) and Fengchi (Gb20).Conclusion: baihui (GV20) and Fengchi (Gb20) can regulate migraine by regulating inflammatory factors and HMOX1， AKT1， STAT3， P-ERK1/ERK2 and other changes in HiF-1 signaling pathway， Signaling by interleukins and inflammatory response pathways. based on systems biology and network pharmacology， and with the model of "acupoint-target-disease"， explore the research methods of systematic acupuncture and moxibustion. We believe this is a usable research direction for exploring the mechanism of acupuncture stimulation.

With the implementation of the "emission peak, carbon neutrality" strategy, the proportion of renewable energy is increasing, and the grid strength of the power system is getting weaker. This leads to high transient over-voltage problems caused by AC short circuits. The paper analyzes the impact of phase-locked loop (PLL) dynamics on the transient over-voltage in a voltage source converter (VSC) due to switching delays after low voltage ride-through (LVRT). The results show that the point of common coupling (PCC) voltage phase generally jumps backward at the moment of fault clearing, and the reactive current during the switching delay no longer equals the reference value due to PLL. When VSC only injects reactive current during LVRT, the phenomenon will improve the transient over-voltage. However, if the active current is injected simultaneously, the transient over-voltage level may deteriorate under some parameters of PLL. in addition, this paper also analyzes the principle of PLL parameter adjustment to ensure that the PLL dynamics improve the transient over-voltage. Electromagnetic transient simulation by MATLAb verifies the results. © 2025 Power System Technology Press. All rights reserved.

Natural biological microtubular networks have undergone adaptive evolutionary selection and may offer viable solutions to design challenges in artificial microtubular networks. The plasmodium of the slime mold Physarum polycephalum(P. polycephalum) extends continuously to form a protoplasmic microtubular network structure, directly connecting food *** simulations revealed that the formation of this adaptive P. polycephalum microtubular network could be captured by a mathematical algorithm. inspired by the P. polycephalum microtubular networks, we propose an adaptive optimization design method for artificial microtubular networks. Specifically, we utilized hydrogels with biodegradable and tissue-adhesive properties to replicate the P. polycephalum microtubular networks via photomask. in Rhodamine b diffusion and glucosecatalyzed reaction experiments, we found that the P. polycephalum microtubular networks exhibited significantly enhanced efficiency compared to vascular and artificial networks. Furthermore, we demonstrated the potential for uric acid(UA) degradation of the hydrogels with a real P. polycephalum microtubular network loaded with urate oxidase(UOx) in a rodent model of hyperuricemia. And this network achieved more than double the effect of the artificial network. This underscores the potential of natural microtubular networks to replace artificial microtubular networks.

in practical water environmental planning, the influence of the non-linear characteristics on the benefit of environmental investment was seldom taken into consideration. This paper demonstrates that there exist a lot of non-linear behaviors in water environment by emphatically analyzing the influence of the non-linear characteristics of the economic scale, the meandering river and the model on water environmental planning, which will make a certain impact on the water environmental planning that sometimes cannot be neglected. This paper also preliminarily explores how to integrate the non-linear characteristics into water environmental planning. The results showed that compared with traditional methods, water environmental planning considering non-linear characteristics has its prevalence and it is necessary to develop the relevant planning theories and methods.
