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.

Objective To establish and test a 3-year prognosis model for elderly intertrochanteric fractures after intramedullary nail fixation.Methods A total of 205 elderly patients with intertrochoteric fracture of femur who underwent intramedullary nail fixation in our hospital from April 2019 to April 2021 were selected for observation study,followed up for 3 years after surgery,according to the Harris score,they were divided into the good group and the poor group.Univariate analysis was conducted to investigate the influencing factors of disease prognosis in the two groups 3 years after surgery.After the variables were screened by LASSO regression and cross-validation method,the independent influencing factors of the 3-year postoperative prognosis were analyzed by multi-factor Logistic regression,and the prediction model of the nomogram was built,and the model was evaluated and validated.Results Among 205 elderly patients with intertrochanteric fractures of the femur who underwent intramedullary nailing fixation,201 were followed up for 3 years.Among them,148 patients had a Harris score of ≥70 points,while 53 patients had a score of＜70 points.Univariate analysis results showed that the poor group had a higher proportion of patients with age,stroke,osteoporosis,Evans-Jensen type Ⅲ and Ⅳ fractures,poor intraoperative reduction,and a tip-apex distance of ≥ 30 mm compared to the good group,and had a lower lateral wall thickness than the good group,the difference was statistically significant(P＜0.05).LASSO regression analysis and cross-validation were used to screen variables.Multivariate Logistic regression analysis showed that stroke(OR=2.127,95％CI:1.478-3.061)and fracture Evans-Jensen classification Ⅲ(OR=1.149,95％CI:1.105-1.195)and type Ⅳ(OR=1.187,95％CI:1.143-1.233),intraoperative reduction was not good(OR=3.290,95％CI:2.319-4.668),apex distance ≥ 30 mm(OR=1.413,95％CI:1.066-1.874)was an independent associated risk factor for disease outcome 3 years after surgery,the external wall thickness(OR=0.600,95％CI:0.428-0.841)was an independent correlated risk factor for 3-year prognosis(P＜0.05).Based on the results of multiple factors,a nomogram prediction model was drawn,and the results showed that the model had certain predictive value for the disease outcome three years after surgery.The evaluation and verification results showed that when the threshold probability was 0-96％,the model had good clinical applicability and positive clinical net benefit.Conclusion Stroke,fracture Evans-Jensen classification Ⅲ and Ⅳ,poor intraoperative reduction,apical distance ≥30 mm,and lateral wall thickness are independent and relevant factors for 3-year prognosis of senile intertrochanteric fractures after intramedullary nail fixation.The establishment of a nematographic model has good predictive value for postoperative long-term prognosis and positive clinical net benefit.It can be used as an effective model to predict the long-term prognosis of postoperative disease.

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.
