Ischemic stroke (IS) is one of the main causes inducing death and disability in adults. Because of the high recurrence rate of IS, prevention of recurrence is of great significance to this population, for which the evidence-based and effective secondary prevention strategy is an important means, and acupuncture intervention has a positive effect on its risk factors. In the present article, we reviewed the progress of researches on the mechanisms of acupuncture underlying prevention of IS relapse from the perspective of its main risk factors, namely 1) hypertension (preventing and controlling the adverse effects caused by the imbalance of blood pressure level, vascular and other tissue structures, endocrine factors and central nervous system activities in patients with hypertension after IS), 2) hypercholesterolemia (lowering serum total cholesterol, triglyceride, low-density lipoprotein-cholesterol (LDL-C) and raising high-density lipoprotein cholesterol), 3) diabetes (regulating the secretion function of adipose tissue, activating the insulin signal transduction pathway, protecting the function of pancreatic ß cells, and regulating the central nervous system functions to participate in the secondary prevention of IS), 4) smoking (relieving the symptoms of smoking cessation and reducing the smoker's dependence on smoking by changing the internal environment, lowering the level of blood endorphin and regulating the excitability of central nervous system), 5) sleep apnea syndrome (regulating local muscle function and the excitability of the nervous system, but also affecting some organic changes as reducing tonsil swelling) and 6) obesity (lowering blood glucose and lipid, increasing the ratio of brown/white fat, reducing leptin resistance, and suppressing appetite to induce body weight loss, or directly regulate the changes of fat tissue, etc). Results shows that the acupuncture's regulatory mechanism for IS risk factors is closely related to the neuroendocrine system, and simultaneously involves multiple targets of multiple risk factors. Due to its good efficacy and safety, acupuncture therapy is of great value for clinical promotion as an important intervention for secondary prevention.

Disease trajectories in older adults with non-AD pathologic change and comparison with Alzheimer's disease pathophysiology: A longitudinal study.

Based on the 'AT(N)' system, individuals with normal amyloid biomarkers but abnormal tauopathy or neurodegeneration biomarkers are classified as non-Alzheimer's disease (AD) pathologic change. This study aimed to assess the long-term clinical and cognitive trajectories of individuals with non-AD pathologic change among older adults without dementia, comparing them to those with normal AD biomarkers and AD pathophysiology. Analyzing Alzheimer's Disease Neuroimaging Initiative data, we evaluated clinical outcomes and conversion risk longitudinally using mixed effects models and multivariate Cox proportional hazard models. We found that compared to individuals with A-T-N-, those with abnormal tauopathy or neurodegeneration biomarkers (A-T + N-, A-T-N + , and A-T + N + ) had a faster rate of cognitive decline and disease progression. Individuals with A-T + N + had a faster rate of decline than those with A-T + N-. Additionally, in individuals with the same baseline tauopathy and neurodegeneration biomarker status, the presence of baseline amyloid could accelerate cognitive decline and clinical progression. These findings provide a foundation for future studies on non-AD pathologic change and its comparison with AD pathophysiology.

Exploring acupuncture treatment strategies for snoring based on meridian theory. / 基于经络学说探析鼾症的针刺治疗思路.

Starting from the perspective of meridian theory, this article briefly analyzes the meridian pathophysiology of snoring and the relationship between snoring and meridian theory. It proposes that acupuncture treatment for snoring should focus on regulating qi from the shaoyang meridians, harmonizing the spirit by the governor vessel, resolving phlegm through the three yang meridians, and harmonizing qi and blood from the yangming meridians. Additionally, attention is placed on both the root cause and the symptoms, the theory of "four seas". The ultimate goal is to promote the flow of meridian and qi-blood, improve symptoms such as nighttime snoring, poor sleep quality, and daytime sleepiness, and achieve the desired outcome of stopping snoring and ensuring restful sleep.

[Application of single-arm objective performance criteria/performance goal in acupuncture-moxibustion clinical trials].

Due to various constraints, such as clinical implementation conditions and unique characteristics of acupuncture-moxibustion, some randomized controlled trials (RCTs) of acupuncture-moxibustion still suffer from relatively low quality and limited applicability. The single-arm objective performance criteria/performance goal can be considered as an ideal supplementary and alternative research approach to RCTs. In this paper, the feasibility of applying the single-arm objective performance criteria/performance goal in acupuncture-moxibustion clinical research is explored from the limitations of conducting acupuncture-moxibustion RCTs, the principles, the essential design considerations and key statistical steps. In addition, illustrative examples are provided. The objective is to offer insights into resolving practical difficulties in acupuncture-moxibustion clinical research.

[Clinical thinking of acupuncture for snoring based on "disharmony qi leads to restlessness"].

This study summarizes the clinical thinking of acupuncture for snoring based on "disharmony qi leads to restlessness". According to the pathological characteristics of qi stagnation and blood stasis, phlegm dampness and internal obstruction in snoring patients, combined with the etiology, pathogenesis and location of the disease, the innovative viewpoint of "disharmony qi leads to restlessness" is proposed. It is believed that the key to snoring treatment lies in "regulating qi ". In clinical practice, acupuncture can directly regulate the qi of the disease's location, regulate the qi of the organs and viscera, and regulate the qi of the meridians to achieve overall regulation of the body's internal and external qi, smooth circulation of qi and blood, and ultimately achieve the therapeutic goal of harmonizing qi, stopping snoring, and improving sleep quality.

Disease trajectories in elders with suspected non-Alzheimer's pathophysiology and its comparison with Alzheimer's disease pathophysiology: a longitudinal study.

Background: According to the new 'AT(N)' system, those with a normal amyloid biomarker but with abnormal tauopathy or biomarkers of neurodegeneration or neuronal injury, have been labeled suspected non-Alzheimer's pathophysiology (SNAP). We aimed to estimate the long-term clinical and cognitive trajectories of SNAP individuals in non-demented elders and its comparison with individual in the Alzheimer's disease (AD) pathophysiology using 'AT(N)' system. Methods: We included individuals with available baseline cerebrospinal fluid (CSF) Aß (A), CSF phosphorylated tau examination (T) and 18F-uorodeoxyglucose PET or volumetric magnetic resonance imaging (N) from the Alzheimer's Disease Neuroimaging Initiative database. Longitudinal change in clinical outcomes are assessed using linear mixed effects models. Conversion risk from cognitively normal (CN) to cognitively impairment, and conversion from mild cognitive impairment (MCI) to dementia are assessed using multivariate Cox proportional hazard models. Results: Totally, 366 SNAP individuals were included (114 A-T-N-, 154 A-T + N-, 54 A-T-N + and 44 A-T + N+) of whom 178 were CN and 188 were MCI. Compared with A-T-N-, CN elders with A-T + N-, A-T-N + and A-T + N + had a faster rate of ADNI-MEM score decline. Moreover, CN older individuals with A-T + N + also had a faster rate of decline in ADNI-MEM score than those with A-T + N- individuals. MCI patients with A-T + N + had a faster rate of ADNI-MEM and ADNI-EF decline and hippocampal volume loss compared with A-T-N- and A-T + N- profiles. CN older individuals with A-T + N + had an increased risk of conversion to cognitive impairment (CDR-GS ≥ 0.5) compared with A-T + N- and A-T-N-. In MCI patients, A-T + N + also had an increased risk of conversion to dementia compared with A-T + N- and A-T-N-. Compared with A-T + N-, CN elders and MCI patients with A + T + N- and A + T + N + had a faster rate of ADNI-MEM score, ADNI-EF score decline, and hippocampal volume loss. CN individuals with A + T + N + had a faster rate of ADNI-EF score decline compare with A-T + N + individuals. Moreover, MCI patients with A + T + N + also had a faster rate of decline in ADNI-MEM score, ADNI-EF score and hippocampal volume loss than those with A-T + N + individuals. Conclusions: The findings from clinical, imaging and biomarker studies on SNAP, and its comparison with AD pathophysiology offered an important foundation for future studies.

The appropriate needle device is crucial for obtaining the curative effect of fire needling therapy. The article introduces the material specification, clinical operation, indications, characteristics and advantages of the contemporary traditional fire needling devices (e.g. He's fire needle and Shi 's fire needle) and the contemporary new-type ones (e.g. fire needling with filiform needle and micro-needle); and determines the innovations of modern fire needling. It is anticipated that the needle specifications, production process and operation standard of fire needling devices should be further unified so as to provide the references for the selection of fire needling devices in treatment based on clinical syndrome differentiation and expand the clinical application of fire needling therapy.

[Innovation, development and application of contemporary fire needling].

Physicians in the past dynasties have improved the theory of fire needling from the aspects of fire needling instruments, clinical efficacy, application scope, operation, precautions, etc., which promoted the clinical application of fire needling. Modern fire needling breaks through the traditional clinical taboos such as heat syndrome, face, forbidden acupoints, and no needle retention. By using modern fire needling with various types, characteristics and functions, multiple needles and multiple methods are used to treat various diseases, which can further exert the therapeutic effect of fire needling and promote the popularization and application of fire needle therapy.

Selective mGluR1 Negative Allosteric Modulator Reduces Blood-Brain Barrier Permeability and Cerebral Edema After Experimental Subarachnoid Hemorrhage.

The blood-brain barrier (BBB) disruption leads to the vasogenic brain edema and contributes to the early brain injury (EBI) after subarachnoid hemorrhage (SAH). However, the mechanisms underlying the BBB damage following SAH are poorly understood. Here we reported that the neurotransmitter glutamate of cerebrospinal fluid (CSF) was dramatically increased in SAH patients with symptoms of cerebral edema. Using the rat SAH model, we found that SAH caused the increase of CSF glutamate level and BBB permeability in EBI, intracerebroventricular injection of exogenous glutamate deteriorated BBB damage and cerebral edema, while intraperitoneally injection of metabotropic glutamate receptor 1(mGluR1) negative allosteric modulator JNJ16259685 significantly attenuated SAH-induced BBB damage and cerebral edema. In an in vitro BBB model, we showed that glutamate increased monolayer permeability of human brain microvascular endothelial cells (HBMEC), whereas JNJ16259685 preserved glutamate-damaged BBB integrity in HBMEC. Mechanically, glutamate downregulated the level and phosphorylation of vasodilator-stimulated phosphoprotein (VASP), decreased the tight junction protein occludin, and increased AQP4 expression at 72 h after SAH. However, JNJ16259685 significantly increased VASP, p-VASP, and occludin, and reduced AQP level at 72 h after SAH. Altogether, our results suggest an important role of glutamate in disruption of BBB function and inhibition of mGluR1 with JNJ16259685 reduced BBB damage and cerebral edema after SAH.

Multiple administrations of human marrow stromal cells through cerebrospinal fluid prolong survival in a transgenic mouse model of amyotrophic lateral sclerosis.

BACKGROUND AIMS: The blood-brain barrier (BBB) is the main obstacle to cell therapy for neurologic disorders such as amyotrophic lateral sclerosis (ALS). Intrathecal injection is a potential method for cell transplantation because it would bypass the BBB. We investigated the effects of human marrow stromal cells (hMSC) delivered through cerebrospinal fluid (CSF) in a transgenic mouse model of ALS. METHODS: 5 x 10(5) hMSC were delivered into the CSF of SOD1 transgenic mice at the age of 8 weeks (single transplantation group) or 8, 10 and 12 weeks (multiple transplantation group). Clinical observation, weight, hanging wire test and motor neuron count were used to assess the disease progression in the SOD1 mice. Immunohistochemistry was performed with human-specific antibody against HuNu to examine the distribution of hMSC in the lumbar spinal cord parenchyma of SOD1 mice at the age of 15 weeks. RESULTS: Single transplantation of hMSC did not have a beneficial effect in SOD1 mice. Multiple transplantations of hMSC attenuated weight loss, enhanced motor performance, decreased motor neuron loss and, importantly, increased survival in SOD1 transgenic mice. However, only a few hMSC delivered through the CSF migrated into the lumbar spinal cord parenchyma of SOD1 mice. CONCLUSIONS: Multiple administrations of hMSC through CSF may have a therapeutic effect in SOD1 mice, although limited numbers of cells migrate into the lumbar spinal cord parenchyma. It is likely that the hMSC remaining in CSF are responsible for the effect in SOD1 mice.

[Correlation between the polymorphism of platelet glycoprotein GPIb α Kozak gene and transient ischemic attack].

OBJECTIVE: Genic susceptibility could increase the risk of transient ischemic attack (TIA). The objective of this study is to investigate the relationship between the polymorphism of platelet glycoprotein GPIb α Kozak gene and TIA in Qindao Han population. METHODS: The polymorphisms of platelet glycoprotein GPIb α Kozak gene -5T/C in TIA patients and normal control were detected with sequence-specific primers polymerase chain reaction (PCR-SSP). RESULTS: The prevalence of the CC genotype and C alleles were significantly higher in TIA patients than in the control group (P<0.05). The positive correlation between C allele and TIA was showed by logistic regression analysis (P=0.016). CONCLUSION: The -5T/C polymorphism of the platelet glycoprotein GPIb α Kozak gene is implicated in the pathogenesis of TIA. C allele is an independent risk factor for TIA.
