Identification of lncRNA-miRNA-mRNA Networks in the Lenticular Nucleus Region of the Brain Contributes to Hepatolenticular Degeneration Pathogenesis and Therapy.

Long non-coding RNAs (lncRNAs) are a recently discovered group of non-coding RNAs that play a crucial role in the regulation of various human diseases, especially in the study of nervous system diseases which has garnered significant attention. However, there is limited knowledge on the identification and function of lncRNAs in hepatolenticular degeneration (HLD). The objective of this study was to identify novel lncRNAs and determine their involvement in the networks associated with HLD. We conducted a comprehensive analysis of RNA sequencing (RNA-seq) data, reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and computational biology to identify novel lncRNAs and explore their potential mechanisms in HLD. We identified 212 differently expressed lncRNAs, with 98 upregulated and 114 downregulated. Additionally, 32 differently expressed mRNAs were found, with 15 upregulated and 17 downregulated. We obtained a total of 1131 pairs of co-expressed lncRNAs and mRNAs by Pearson correlation test and prediction and annotation of the lncRNA-targeted miRNA-mRNA network. The differential lncRNAs identified in this study were found to be involved in various biological functions and signaling pathways. These include translational initiation, motor learning, locomotors behavior, dioxygenase activity, integral component of postsynaptic membrane, neuroactive ligand-receptor interaction, nuclear factor-kappa B (NF-κB) signaling pathway, cholinergic synapse, sphingolipid signaling pathway, and Parkinson's disease signaling pathway, as revealed by the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. Six lncRNAs, including XR_001782921.1 (P < 0.01), XR_ 001780581.1 (P < 0.01), ENSMUST_00000207119 (P < 0.01), XR_865512.2 (P < 0.01), TCONS_00005916 (P < 0.01), and TCONS_00020683 (P < 0.01), showed significant differences in expression levels between the model group and normal group by RT-qPCR. Among these, four lncRNAs (TCONS_00020683, XR_865512.2, XR_001780581.1, and ENSMUST00000207119) displayed a high degree of conservation. This study provides a unique perspective for the pathogenesis and therapy of HLD by constructing the lncRNA-miRNA-mRNA network. This insight provides a foundation for future exploration in this field.

Acupoint compatibility effect: increasing "effect value" and expanding "effect domain". / è §ç©´é ä¼æ•ˆåº”.

By summarizing and exploring the theoretic connotation, key of functions and effect mechanism of acupoint compatibility, the effect of acupoint compatibility is concluded as the increase of "effect value" and the expansion of "effect domain". The increase of "effect value" is the concrete embodiment by the value of medical assessment scale, the value of objective index detection in clinical trial and the value of index detection in experiment research. The expansion of "effect domain" is the increase of effect target and the extension of effect scope. The paper interprets the scientific connotation of acupoint compatibility therapy from a new perspective, and emphasizes the innovative approaches to research while bringing forth new ideas on the research method. It is anticipated that a novel breakthrough can be achieved in the study of acupoint compatibility and the improvement of acupuncture-moxibustion efficacy.

Antipsychotic drugs induce vascular defects in hematopoietic organs.

Antipsychotic agents are clinically utilized to treat schizophrenia and other mental disorders. These drugs induce neurological and metabolic side effects, but their influence on blood vessels remains largely unknown. Here, we show that haloperidol, one of the most frequently prescribed antipsychotic agents, induces vascular defects in bone marrow. Acute haloperidol treatment results in vascular dilation that is specific to hematopoietic organs. This vessel dilation is associated with disruption of hematopoiesis and hematopoietic stem/progenitor cells (HSPCs), both of which are reversible after haloperidol withdrawal. Mechanistically, haloperidol treatment blocked the secretion of vascular endothelial growth factor A (VEGF-A) from HSPCs. Genetic blockade of VEGF-A secretion from hematopoietic cells or inhibition of VEGFR2 in endothelial cells result in similar vessel dilation in bone marrow during regeneration after irradiation and transplantation. Conversely, VEGF-A gain of function rescues the bone marrow vascular defects induced by haloperidol treatment and irradiation. Our work reveals an unknown effect of antipsychotic agents on the vasculature and hematopoiesis with potential implications for drug application in clinic.

Operator radiation dose during trans-hepatic arterial chemoembolization: different patients' positions via transradial or transfemoral access.

PURPOSE This study aimed to compare the radiation dose received by the operator among different patients' positions via transradial access (TRA) or transfemoral access (TFA) during transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). METHODS A total of 120 patients with HCC undergoing TACE for the first time between January and November 2019 were randomized into 4 groups with 30 patients in each group. In group A, patients were placed in the foot-first position with the left upper arm abducted, and TACE was performed via the left radial artery. In group B, patients were placed in the conventional headfirst position with the left hand placed at the left groin, and TACE was performed via the left radial artery. In group C, patients were placed in the conventional head-first position, and TACE was performed via the right radial artery. In group D, patients were placed in the conventional head-first position, and TACE was performed via the right femoral artery. Before each procedure, thermoluminescent dosimeters were taped at 7 different body parts of the operator and the radiation dose was measured and collected after the procedure. The normalized radiation dose was also calculated. Procedural parameters included radiation dose, fluoroscopy time (FT), dose-area product (DAP), and air kerma (AK) were recorded. Patients' demographics, tumor baseline characteristics, radiation dose, and procedural parameters were compared between groups. RESULTS No significant differences were found in patients' demographics, tumor baseline characteristics, as well as in total FT, DAP, and AK. However, significant differences were found in the total radiation dose received by the operator and the doses on the pelvic cavity and the right wrist (P < .05). In group C, the radiation doses received on the pelvic cavity, the right wrist, and the total radiation doses were relatively higher. Significant differences were also found in the normalized radiation doses received by the operator on the thyroid, chest, left wrist, right wrist, and pelvic cavity, and the total normalized doses (all P < .05). Similarly, the radiation doses received by the operator at the aforementioned parts in group C were higher, while those in group A were lower. CONCLUSION No statistically significant differences were observed in the FT, DAP, and AK in TACE via TRA when patients were placed in different positions. However, TACE via the left TRA, with patients in the feet-first position, reduced the radiation dose received by the operator, thereby reducing the radiation risk.

Location-Based LTE-M Uplink Power Control and Radio Resource Scheduling.

Long-Term Evolution for Metro (LTE-M) is adopted as the data communication system in urban rail transit to exchange bio-direction train-wayside information. Reliable data communication is essential in LTE-M systems for ensuring trains' operation safety and efficiency. However, the inter-cell inference problem exists in LTE results in throughput reduction, especially when trains are in the edge area of adjacent cells, and has negative effects on train operation. The uplink power control and radio resource scheduling scheme is studied in LTE-M system which differentiates from public cellular networks in user numbers and the availability of the trains' locations. Since the locations of the trains are available, the interferences from the neighbouring cells can be calculated, and a location based algorithm together with soft frequency reuse is designed. In addition, a proportional fair algorithm is taken to improve uplink radio resource scheduling considering the fairness to different train-wayside communication service requirements. Through simulation, the practicability of the proposed schemes in communication system of urban rail transit is verified in aspects of radio power control and data communication throughput.

Dysfunction of the Lenticular Nucleus Is Associated with Dystonia in Wilson's Disease.

Dysfunction of the lenticular nucleus is thought to contribute to neurological symptoms in Wilson's disease (WD). However, very little is known about whether and how the lenticular nucleus influences dystonia by interacting with the cerebral cortex and cerebellum. To solve this problem, we recruited 37 WD patients (20 men; age, 23.95 ± 6.95 years; age range, 12-37 years) and 37 age- and sex-matched healthy controls (HCs) (25 men; age, 25.19 ± 1.88 years; age range, 20-30 years), and each subject underwent resting-state functional magnetic resonance imaging (RS-fMRI) scans. The muscle biomechanical parameters and Unified Wilson Disease Rating Scale (UWDRS) were used to evaluate the level of dystonia and clinical representations, respectively. The lenticular nucleus, including the putamen and globus pallidus, was divided into 12 subregions according to dorsal, ventral, anterior and posterior localization and seed-based functional connectivity (FC) was calculated for each subregion. The relationships between FC changes in the lenticular nucleus with muscle tension levels and clinical representations were further investigated by correlation analysis. Dystonia was diagnosed by comparing all WD muscle biomechanical parameters with healthy controls (HCs). Compared with HCs, FC decreased from all subregions in the putamen except the right ventral posterior part to the middle cingulate cortex (MCC) and decreased FC of all subregions in the putamen except the left ventral anterior part to the cerebellum was observed in patients with WD. Patients with WD also showed decreased FC of the left globus pallidus primarily distributed in the MCC and cerebellum and illustrated decreased FC from the right globus pallidus to the cerebellum. FC from the putamen to the MCC was significantly correlated with psychiatric symptoms. FC from the putamen to the cerebellum was significantly correlated with muscle tension and neurological symptoms. Additionally, the FC from the globus pallidus to the cerebellum was also associated with muscle tension. Together, these findings highlight that lenticular nucleus-cerebellum circuits may serve as neural biomarkers of dystonia and provide implications for the neural mechanisms underlying dystonia in WD.

Scheme optimization of acupoints compatibility and influence factors of the effect.

BACKGROUND: Acupuncture may be a clinically effective treatment for insomnia. We will perform a multicenter, large-scale, single-blinded, randomized controlled trial to compare the differences in the clinical efficacy between the use of singleacupoints and compatibilityacupoints in the treatment of primary insomnia. METHODS/DESIGN: A total of 333 participants will be randomly assigned to 2 acupoint treatment groups or 1 nonacupoint control group in a 1:1:1 ratio by a central stochastic system. The acupuncture groups are: the single acupoint group: Shenmen (HT7); and he compatibility acupoint group: Shenmen (HT7), Baihui (DU20), and Sanyinjiao (SP6). The observation period of this trial will be 10 weeks. All patients will be followed for 1 week before randomization (baseline phase). After randomization, the patients will receive 30 minutes of electro-acupuncture once per day for 5 weeks. In the fourth week after the treatment, follow-up will be performed once. The primary outcome will be the Pittsburgh sleep quality index score at 1 week before randomization and 2 and 8 weeks after randomization. The secondary outcomes will include data from sleep diaries, Athens insomnia scale scores, ShortForm-36 Health Survey scores, electroencephalogram technology results and polysomnogram) results. Patients will be required to complete a sleep diary every day during the treatment period. Patients will also undergo electroencephalogram technology and polysomnogram 1 week before randomization and 5 weeks after randomization. The other secondary outcomes will be measured 1 week before randomization and 5 and 9 weeks after randomization. DISCUSSION: This trial will be helpful in identifying whether acupuncture at compatibility acupoints is more effective than acupuncture at single acupoints.

Effects of High-Frequency Repetitive Transcranial Magnetic Stimulation on Upper Limb Dystonia in Patients With Wilson's Disease: A Randomized Controlled Trial.

Background: Upper limb dystonia is a frequent complication of Wilson's disease (WD). It can lead to poor quality of life and disability. Currently, no effective treatment for it exists. Therefore, we carried out a clinical trial to determine whether high frequency repetitive transcranial magnetic stimulation (rTMS) on the primary motor cortex alleviates upper limb dystonia in WD patients. Methods: This study was a single-center, double-blind, randomized clinical study, included 60 WD patients with upper limb dystonia from a research base of WD in Hefei, China. Participants were randomly divided into a treatment group (TG) and a control group (CG). The TG received rTMS at 10 Hz, while the CG received sham stimulation for 7 consecutive days. Participants were assessed at baseline, after the seventh treatment session, and at 2 and 4 weeks after the seventh treatment session. The primary outcomes included patients' objective muscle tension and stiffness as measured with the MyotonPRO device. The secondary results were scores on clinical scales assessing muscle spasm and motor symptoms, which included the Modified Ashworth Scale (MAS), Unified Wilson's Disease Rating Scale (UWDRS), Burke Fahn Marsden Scale (BFM), and the Activities of Daily Living (ADL) scale. Results: The analysis revealed that after 10 Hz rTMS, muscle tension (P < 0.01) and stiffness (P < 0.01) as measured by the MyotonPRO device decreased significantly in the TG compared to the CG. Moreover, clinically relevant scale scores, including the MAS (P < 0.01), UWDRS (P < 0.01), BFM (P < 0.01), and ADL (P < 0.01) were also significantly reduced. Conclusion: High-frequency rTMS over the primary motor cortex may be an effective complementary and alternative therapy to alleviating upper limb dystonia in WD patients.

[Acupuncture preconditioning at "Zusanli"(ST36) and "Zhongwan"(CV12) prevents stress gastric ulcer by regulating the TLR4/MyD88/IκB signaling pathway].

OBJECTIVE: To observe the effect of electroacupuncture preconditioning at "Zusanli"(ST36，Lower Confluent point) and "Zhongwan"(CV12，Front-Mu point) combination on oxidative stress and inflammation-related indicators, Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88) and inhibitor-α of nuclear transcription factor κB (IκB-α) in serum and gastric tissue of rats with stress gastric ulcer(SGU)，so as to explore its mechanisms underlying prevention of SGU. METHODS: A total of 36 Wistar rats were randomly divided into blank control, model, positive drug and He-Sea-Front-Mu point combination groups (n=9 in each group). A rat model of SGU was established by restraint water-immersion stress method. Ten days before mode-ling, rats in the He-Sea-Front-Mu point combination group received electroacupuncture （2 Hz, 0.6 mA）at ST36 and CV12 for 10 min once every other day for 10 days, and those in the positive drug group was treated by gavage of omeprazole (20 mg/kg) once every other day for 10 days. The morphology of the gastric mucosa was observed by naked eyes and hematoxylin-eosin staining, and the ulcer index (UI) and lesion score were calculated. TBA and colorimetric methods, ELISA and Western blot were used to detect malondialdehyde (MDA), myeloperoxidase (MPO), glutathione peroxidase (GSH-Px), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels and the relative expressions of TLR4, MyD88, and IκB-α protein, separately. RESULTS: The gastric mucosa of rats in the blank control group was smooth and intact, the cells were arranged neatly, and there was no telangiec-tasia, hyperemia and inflammatory cell infiltration. The gastric mucosal epithelial structure of rats in the model group was destroyed, and a large number of mucosal epithelial cell death and inflammatory cell infiltration were seen. The degree of gastric mucosal injury and inflammatory cell infiltration in the positive drug group and the combined point group was less than that in the model group. Compared with the blank control group, the UI and lesion score of rats in the model group were significantly increased (P<0.05), the levels of MDA and MPO in the serum and gastric tissues were significantly increased (P<0.05), GSH-Px was significantly reduced (P<0.05), the contents of TNF-α and IL-6 in serum were markedly increased (P<0.05), the expression levels of TLR4 and MyD88 proteins in gastric tissue were significantly increased (P<0.05), IκB-α was significantly reduced (P<0.05). After intervention and in comparison with the model group showed that, the UI and lesion score, the levels of MDA and MPO, contents of serum TNF-α and IL-6, expression levels of TLR4 and MyD88 proteins in positive drug and He-Sea-Front-Mu point combination groups were significantly decreased (P<0.05), while GSH-Px and IκB-α were significantly increased (P<0.05); There were no significant differences in the above indicators between the positive drug and the He-Sea-Front -Mu point combination groups （except TNF-α）. CONCLUSION: Electroacupuncture preconditioning at ST36 and CV12 can prevent SGU, which may be related to its effects in anti-oxidant, anti-inflammatory and regulating TLR4/MyD88/IκB signaling pathway.

Identification of mutations in the ATP7B gene in 14 Wilson disease children: Case series.

INTRODUCTION: Wilson Disease (WD) is an autosomal recessive inherited metabolic disease caused by mutations in the ATPase copper transporting beta gene (ATP7B). WD can cause fatal neurological and hepatic disorders if not diagnosed and treated. OBJECTIVE: To analyze the disease-causing mutations of 14 Chinese WD children, 11 of whom are diagnosed with hepatic disorders, 2 with neurological degeneration and 1 with both hepatic and neurological disorders. METHODS: All ATP7B coding regions were analyzed by Sanger sequencing. Single nucleotide polymorphisms (SNPs) functional impacts were assessed by combining the results of four bioinformatics tools (Poly-phen-2, SIFT, PANTHER-PSEP and PhD-SNPs) in an index that reflects the combined probability (cPdel) of an amino acid change to be deleterious to the protein function. RESULTS: Two novel variants involved in WD development, c.1448_1455del (p.Arg483SerfsX19) and c.4144G>T (p.Glu1382Stop), and 11 previously reported mutations were detected. Both new variants result in shortened and dysfunctional ATP7B proteins. cPdel score suggests that SNPs may be deleterious to the ATP7B functionality. CONCLUSIONS: This study enriches the library of the ATP7B mutations that lead to WD and can be used as a basis for genetic counseling, for WD prevention and clinical and prenatal diagnosis. Those SNPs that are believed to be harmless to ATP7B protein may be involved in the pathogenesis of WD.

Quality of internet videos related to exercise therapy of ankylosing spondylitis from mainland China : Content analysis.

OBJECTIVE: The aim of this study is to assess the quality and reliability of online videos on ankylosing spondylitis (AS) exercises from the five most popular video websites in China. DESIGN: Cross-sectional and descriptive study. METHODS: We searched the video websites of Youku, Tencent, Tudou, IQiYi, and bilibili on February 15, 2020, using the keywords "Ankylosing spondylitis exercise" "Ankylosing spondylitis rehabilitation" and "Ankylosing spondylitis therapy" A total of 114 videos were included in the study and evaluated according to the Global Quality Scale (GQS) and modified DISCERN tool. RESULTS: According to the GQS, the videos were classified as high quality (12.3%, n = 14), intermediate quality (63.2%, n = 72), and low quality (24.6%, n = 28). Using the modified DISCERN tool, the videos were divided into useless (53.5%, n = 61), useful (35.1%, n = 40), and misleading (11.4%, n = 13). CONCLUSION: The analysis shows that the quality and reliability of online videos related to exercise therapy for Ankylosing spondylitis (AS) should be improved and supervised in China. Hospitals, universities, and medical doctors should make more useful and high-quality videos to provide effective exercise guidance for AS patients.

GanDouLing promotes proliferation and differentiation of neural stem cells in the mouse model of Wilson's disease.

Wilson's disease (WD) is an autosomal recessive disease caused by mutation of the ATPase copper transporting ß (ATP7B) gene, resulting in abnormal copper metabolism. We aimed to investigate the protective effect of GanDouLing (GDL) on neural stem cell (NSC) function in a mouse model of WD. NSCs were treated with different concentrations of GDL alone or in combination with penicillamine, following which we evaluated cellular growth, apoptosis, and differentiation. Nuclear factor E2-related factor 2 (Nrf2) pathway and NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation were analyzed via Western blotting. Treatment with GDL alone or in combination with penicillamine significantly increased proliferation and inhibited apoptosis of NSCs in a dose-dependent manner. In addition, GDL treatment remarkably promoted differentiation of NSCs. Consistently, levels of class III ß-tubulin (Tuj1) and microtubule-associated protein 2 (MAP2) were significantly elevated, whereas glial fibrillary acidic protein (GFAP) levels were obviously suppressed in the presence of GDL or penicillamine. In vivo assays confirmed that GDL increased the ratio of Ki67+, Tuj1+, and MAP2+ cells and suppressed apoptosis in the hippocampal region in WD mice. Behavioral assays revealed that both GDL and penicillamine improved memory ability in WD models. Mechanistically, GDL treatment led to activation of Nrf2 signaling and suppression of the NLRP3 inflammasome in WD mice. Notably, inhibition of Nrf2 signaling reversed the protective effects of GDL on hippocampal NSCs. Collectively, these findings demonstrate that GDL exerts a protective effect on NSCs and promotes neurogenesis by targeting Nrf2 signaling and the NLRP3 inflammasome in WD.

A novel versatile instrument for combined studies of persistent luminescence, thermoluminescence, and mechanoluminescence in micro-scale.

This paper presents a new method for combined measurements of persistent luminescence (PersL), thermoluminescence (TL), and mechanoluminescence (ML) of luminescent materials in the micrometer scale. Both the hardware and software designs have been illustrated in detail, and the experimental procedures to execute the emission map, PersL, TL, and ML measurements have been demonstrated. The PersL, TL, and ML properties of the SrAl2O4:Eu2+, Dy3+ micropowder, as well as the corresponding temperature variable emission spectra, have been measured. The results show good agreement with published investigations, indicating the accomplishment of designed functions. The instrument would be a powerful tool for exploring phosphorescent materials in the micrometer and smaller scales.

[Professor WANG Fu-chun's experience of four elements of acupuncture manipulation practice].

Through collecting the 30-year medical experience of professor WANG Fu-chun, the methods of acupuncture manipulation practice were summarized so as to provide the reference for the medical staffs in acupuncture teaching and clinical work. Professor WANG proposes four key elements of acupuncture manipulation practice, i.e. the style of needling practice, the consciousness of needling practice, the strength of needling practice and qi of needling practice. Acupuncture manipulation is a highly operational clinical skill. The knowledge learning from the experience of the instructors is the important way to improve acupuncture techniques. Besides, beginners need to improve their techniques through learning the theories, a large amount of exercises as well as the self-perception.
