ObjectiveTo clarify whether METTL14 mediates the core role of acupuncture at Neiguan (PC6) in promoting myelination and improving behavior in young autistic rats through gene intervention technology. MethodsThe ASD model was established by intraperitoneal injection of valproic acid (VPA) in pregnant rats. Male offspring were intracerebroventricularly injected with adenovirus-packaged METTL14 shRNA (sh-METTL14) or its control (sh-NC) on postnatal day 1, with a model group set as well. Subsequently, the juvenile rats were divided into model group, acupuncture group, acupuncture+sh-NC group, and acupuncture+sh-METTL14 group. The acupuncture group received acupuncture at Neiguan (PC6) from postnatal day 7, once daily for 21 consecutive days. Neurobehavioral changes were evaluated by behavioral tests; METTL14 knockdown efficiency and the expression of METTL14, METTL3, and PTEN were detected by quantitative real-time PCR (qRT-PCR) and Western blot (WB); PTEN m⁶A levels were measured by RNA immunoprecipitation-qPCR (RIP-qPCR); myelin ultrastructure, expression of myelin basic protein (MBP) and neurofascin 155 (NF155), and dendritic spine density were observed using transmission electron microscopy (TEM), enzyme-linked immunosorbent assay (ELISA), immunofluorescence, qRT-PCR, and primary neuron culture. ResultsBehaviorally, knockdown of METTL14 significantly counteracted the beneficial effects of acupuncture in improving self-grooming, open field exploration, three-chamber social interaction, and Morris water maze learning and memory (P<0.05, P<0.01). Compared with the acupuncture+sh-NC group, the acupuncture+sh-METTL14 group showed significantly decreased mRNA and protein expression of hippocampal METTL14 (P<0.01), and the upregulating effects of acupuncture on METTL3 and PTEN expression were reversed (P<0.01). Meanwhile, knockdown of METTL14 significantly inhibited the acupuncture-induced increase in PTEN m⁶A levels (P<0.01). Morphologically, knockdown of METTL14 attenuated the improvement of myelin structure by acupuncture, reversed the downregulation of MBP and upregulation of NF155 induced by acupuncture, and blocked the increase in dendritic spine density (P<0.05, P<0.01). ConclusionMETTL14 is a key molecule mediating the therapeutic effect of acupuncture at Neiguan. Acupuncture at Neiguan upregulates METTL14, thereby enhancing m⁶A methylation modification of PTEN mRNA to stabilize its expression, ultimately promoting myelin development and improving behavioral symptoms in ASD juvenile rats. This preliminarily reveals the modern biological connotation of “opening Xuanfu and dredging myelin”.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

Aim Mouse model of myocardial hypertro-phy was established via intraperitoneal injection of iso-proterenol(ISO)in mice.This approach allows for an in-depth investigation into the pharmacological effects and mechanisms of action of emodin,offering novel in-sights and directions for the improvement of myocardial hypertrophy.Methods The mice were randomly di-vided into the following groups:control group(CON),emodin group(EMO),MAPK activator control group(EMO+Ani),model group(ISO),treatment group(ISO+EMO),and activator intervention group(ISO+EMO+Ani).After treatment with emodin and inter-vention with MAPK activator,the heart weight ratio and cardiac size of each group were observed.Hematoxy-lin-eosin(HE)staining was used to observe the patho-logical changes in cardiac tissue,and kits were utilized to measure the levels of GSH,LDH,and MDA in the serum.Western blot was employed to detect the protein expression levels of inflammatory and oxidative factors,as well as p-p38,p-ERK,p38,and ERK in cardiac tis-sue.Results Emodin can significantly inhibit the production of myocardial inflammatory and oxidative factors induced by ISO,thereby effectively alleviating the degree of myocardial hypertrophy and fibrosis.Af-ter the p38/ERK signaling pathway was specifically ac-tivated by farnesol,the improvement effect of emodin on myocardial hypertrophy was weakened.Further comparison revealed that,compared with the myocardi-al hypertrophy pathological model group,the pathologi-cal protein expression levels in the farnesol-treated group showed no significant difference,and were even higher in some indicators.Conclusion Emodin can effectively inhibit the release of inflammatory factors and improve the state of oxidative stress by modulating the p38/ERK signaling pathway,thereby exerting an ameliorative effect on myocardial hypertrophy.

Objective To observe the effect of acupuncture synchronized with speech training on speech function of patients with post-stroke motor aphasia.Methods Sixty inpatients with post-stroke motor aphasia were selected from the Affiliated Hospital of Shandong Univer-sity of Traditional Chinese Medicine,from January to August,2023.They were randomly divided into control group(n=30)and synchronous group(n=30).Both groups received acupuncture and speech training;the con-trol group received acupuncture in the morning and speech training in the afternoon,while the synchronous group received acupuncture and speech training synchronously,for three weeks.They were assessed with Chi-nese Rehabilitation Research Center Standard Aphasia Examination(CRRCAE),Non-Language-Based Cognitive Assessment(NLCA)and Communication Activities of Daily Living(CADL)before and after treatment.Results The subscores of CRRCAE and NLCA,and score of CADL increased in both groups(|t|>2.081,P<0.05)after treatment,and they were better in the synchronous group than in the control group(|t|>2.680,P<0.05).Conclusion Synchronous mode of acupuncture and speech training is more effective on post-stroke motor aphasia than time-sequence mode.

Objective To observe the effect of synchronous acupuncture and articulation training on spastic dysarthria after stroke.Methods From January to August,2023,64 stroke patients in the Affiliated Hospital of Shandong University of Tradi-tional Chinese Medicine were selected,and randomly divided into control group(n=32)and synchronous group(n=32).Both groups received routine neurological treatment and basic articulation training.The control group added asynchronous acupuncture,while the synchronous group added synchronous acupuncture,for four weeks.Before and after treatment,the modified Frenchay Dysarthria Assessment(m-FDA),Speech Intelligibility Test(SIT),maximum phonation time(MPT)and maximum counting ability(MCA)were used to evaluate the curative effects.Results After treatment,the scores of m-FDA in all the dimensions decreased in both groups(t>2.882,P<0.01);ex-cept for the jaw dimension,the scores of m-FDA in reflexes,respiration,lips,soft palate,larynx,tongue and speech dimensions were significantly lower in the synchronous group than in the control group(t>2.050,P<0.05).After treatment,the results of SIT,and MPT and MCA significantly increased in both groups(t>21.061,P<0.001),and they were better in the synchronous group than in the control group(t>11.412,P<0.001).Conclusion Synchronous acupuncture and articulation training can effectively alleviate the severity of spastic dysarthria after stroke,which was superior to asynchronous acupuncture and articulation training.

Objective:To observe the effect of acupuncture synchronized exercise therapy on sensory and motor functions of lower limbs in stroke patients,and to provide scientific basis for the optimization of rehabilitation program for stroke patients.Method:Seventy stroke patients hospitalized in the Rehabilitation Department of the Affiliated Hospital of Shan-dong University of Traditional Chinese Medicine from March 2022 to July 2022 were selected and randomly di-vided into synchronous group and control group,35 patients in each group.The patients in the synchronous group received routine exercise therapy and synchronized acupuncture treatment,while the patients in the con-trol group received acupuncture and subsequent exercise therapy continuously.Before and after treatment,the revised Nottingham sensory assessment scale(reNSA),Fugl-Meyer sensory rating scale,Fugl-Meyer motor function assessment(FMA),Berg rating scale,modified Barthel index rating scale(MBI)and modified Ash-worth spasm rating scale(MAS)were used to evaluate the curative effects.Result:After treatment,the scores of reNSA deep sensation,reNSA compound sensation and Fugl sensation in two groups were significantly increased(P<0.05).The scores of deep and shallow sensation in the synchro-nous group were significantly higher than those in the control group,while there was no significant difference between the two groups in the scores of compound sensation and Fugl sensation(P>0.05).After treatment,the FMA-UE score,Berg score and MBI score in the two groups were significantly increased(P<0.05),and the FMA-UE score,Berg score and MBI score of the synchronous group were also significantly higher than those of the control group(P<0.05).The composition of MAS scores in both groups also improved significant-ly after treatment,but there was no significant difference between the two groups before or after treatment(χ2=2.469,P=0.650;χ2=1.651,P=0.648).Conclusion:Acupuncture synchronized exercise therapy can effectively improve the sensory and motor functions of the lower limbs after stroke,and its effect is better than that of exercise therapy and acupuncture sequen-tial therapy.
