Control of dual-channel optical bistability in a carbon nanotube nanoresonator coupled with a metallic nanoshell.

We theoretically present a flexible method to obtain dual-channel optical bistability (OB) in a coupled system consisting of a metallic nanoshell (MNS) and a carbon nanotube (CNT) nanomechanical resonator (NR) beyond the dipole approximation. The MNS is made of a metallic core and a dielectric shell. The results show that, the four-wave mixing signal is suppressed significantly due to multipole polarizations in comparison to that in the dipole approximation.

Exploring the causal association between serum metabolites and erectile dysfunction: a bidirectional Mendelian randomisation study.

Erectile dysfunction is a common sexual disorder in men. Some studies have found a strong association between some serum metabolites and erectile dysfunction. To investigate this association further, we used bidirectional Mendelian randomisation to investigate causality and possible biological mechanisms.

Causal effects of gut microbiota on the risk of erectile dysfunction: a Mendelian randomization study.

Erectile dysfunction ranks among the prevalent sexual disorders in men. Several studies have indicated a potential link between gut microbiota and erectile dysfunction. To validate this potential association, we were to screen statistical data from genome-wide association studies of gut microbiota and erectile dysfunction.

DLEU7-AS1 promotes renal cell cancer by silencing the miR-26a-5p/coronin-3 axis.

Long non-coding RNAs (lncRNAs) have been implicated in the progression and development of many types of cancer by interacting with RNA, DNA and proteins, including DLEU7-AS1. However, the function of DLEU7-AS1 in renal cell cancer (RCC) remains unclear. In this study, two prediction algorithms were used to discover the potential target of miR-26a-5p, which was determined to be a tumor suppressor gene, possibly DLEU7-AS1, through the downregulation of coronin-3 in RCC.

Multidimensional Assessment of Electroencephalography in the Neuromodulation of Disorders of Consciousness.

In the present study, we aimed to elucidate changes in electroencephalography (EEG) metrics during recovery of consciousness and to identify possible clinical markers thereof. More specifically, in order to assess changes in multidimensional EEG metrics during neuromodulation, we performed repeated stimulation using a high-density transcranial direct current stimulation (HD-tDCS) protocol in 42 patients with disorders of consciousness (DOC). Coma Recovery Scale-Revised (CRS-R) scores and EEG metrics [brain network indicators, spectral energy, and normalized spatial complexity (NSC)] were obtained before as well as fourteen days after undergoing HD-tDCS stimulation.

Long non-coding RNAs are a diverse catalog of RNAs that have been implicated in various aspects of tumorigenesis. Emerging evidence indicates that they play crucial roles in tumor growth, disease progression, and drug resistance. However, the clinical significance of lncRNAs in tumor behavior prediction and disease prognosis as well as the underlying mechanism in renal cell carcinoma (RCC) remains elusive.

SLC7A11 negatively associates with mismatch repair gene expression and endows glioblastoma cells sensitive to radiation under low glucose conditions.

The cystine/glutamate antiporter xCT (SLC7A11) is frequently upregulated in many cancers, including glioblastoma (GBM). SLC7A11-mediated cystine taken up is reduced to cysteine, a precursor amino acid for glutathione synthesis and antioxidant cellular defense. However, little is known about the biological functions of SLC7A11 and its effect on therapeutic response in GBM.

[Origin and development of 's acupuncturing sensation technique].

Based on 's personal experience, teaching experience, works as well as ancient books of similar times, this paper discusses the origin and development of 's acupuncturing sensation technique, and analyzes the reasons why this technology has been lost. The formation of this technique is influenced by the descriptions of "regulating " "arrival of " and "reaching i" in () and , and combines with the clinical summary of conduction direction and specific position of acupuncturing sensation. Due to 's personal experience, the inheritance characteristics of acupuncture technology and the background of his times, this technology may have been lost, but it still affects the acupuncture concept and practice of " reaching affected area" in later generations.

[Characteristics of clinical effectiveness of bloodletting and proposed ways of mechanism research].

According to the operative characteristics, the stimulated site and the curative effect-emerged site of bloodletting therapy, its clinical characteristics may be divided into three categories: a) local stimulation induced focus-local effect, b) local stimulation induced effect of the distal target organ (point-to-point distal effect), and c) special point stimulation induced broader effect of the whole body. Accordingly, the underlying mechanisms of clinical outcomes mainly involve the improvement of the local microcirculation and secondary changes of inflammatory substances for the first category (local focus). The point-to-point distal effect might mainly involve the innervation of nerve segments, while the broad effect of specific acupoint stimulation might involve multiple levels of the neuro-endocrine-immune system.

IDH1-R132H Suppresses Glioblastoma Malignancy through FAT1-ROS-HIF-1α Signaling.

Background: Glioblastoma (GBM) is one of the most deadly primary malignant brain tumors in adults. R132H mutation of isocitrate dehydrogenase 1 (IDH1) predicts a better prognosis of GBM. IDH1-R132H is associated with increased hypoxia-inducible factor-1α (HIF-1α) expression in GBM tumors.

[Discussion on the needling technique with filiform needle in acupuncture-moxibustion teaching materials in the Republic of China].

Through collecting the literature data of the needling technique with filiform needle in 20 acupuncture-moxibustion teaching materials in the Republic of China， the manipulation techniques with filiform needle were analyzed, such as the technique of needle insertion, the technique of reinforcing and reducing, and the management of acupuncture abnormal conditions, as well as manual techniques and analgesics methods. It is found that the era of the Republic of China was the transition period of traditional acupuncture techniques to the modern ones in acupuncture-moxibustion teaching materials, in which, the twirling technique was predominated in the technique of needle insertion. In that period, the insertion technique of tube needle had been introduced and simplified, the theory and method of the new-style technique of reinforcing and reducing were emerged and the types of acupuncture abnormal conditions recorded in the teaching materials were different from those at present.

Auricular Intradermal Acupuncture as a Supplementary Motor Rehabilitation Strategy in Poststroke Patients: A Randomized Preliminary Clinical Study.

We have explored the potential of auricular intradermal acupuncture (AIA) in standard rehabilitation and acupuncture treatment for motor recovery in poststroke patients. This was a randomized, controlled preliminary clinical study in which the patients were randomly assigned to the CT group (conventional treatment, standard rehabilitation, and routine acupuncture) or AIA group (AIA combined with conventional treatment) and underwent 6 sessions in 1 week (6 days). Standard procedures and previously reported acupuncture points were used.

miR-26 suppresses renal cell cancer via down-regulating coronin-3.

Coronin-3 (coronin-1C), a homotrimer F-actin-binding protein, has been reported to be important for metastasis in several types of cancers such as lung cancer, gastric cancer, and breast cancer. Here, we present an investigation of the expression and function of coronin-3 in renal cell cancer for the first time. We also confirmed that miR-26 directly targets coronin-3 and down-regulates its expression by western blot assay and dual-luciferase reporter system.

In this paper, we expound the origin and development of special acupuncture needle tools for cutaneous region, and discuss its mechanisms from modern medical theory. By consulting related acupuncture books and literature and in combination with needles used in clinical practice, we conclude that acupuncture needle tools can be divided into skin massage needle (digital pressing, spoon needle, etc.), cutaneous pricking blood needle (shear needle, three-edged needle, plum blossom needle, etc.

[Parameters and connotations of quantity of mild moxibustion stimulation].

The quantity of mild moxibustion stimulation is an important factor affecting clinical therapeutic effect. In the present study, we collected related literature by using key word "moxibustion stimulation quantity" from CNKI Database and make a summary about its concept. The quantity of mild moxibustion stimulation has two common characters, namely thermal intensity and cumulative stimulating quantity, and contains 6 components (parameters), including thermal energy, thermal stimulus, heated area of the skin, and stimulating duration, intensity and frequency.

[Analysis on the origin and development of elements of reinforcing and reducing needling techniques].

Reinforcing and reducing needling manipulations are important factors affecting clinical therapeutic effect. In the present paper, the relevant elements of the reinforcing and reducing techniques of acupuncture needle including the left- and right-ward twirling, gender, needling at the left and right, front and back parts of the body, needling along or against the running course of the meridian, and their origin and development recorded in ancient Chinese medical books were collected and sorted out, followed by analysis on the understandings of Chinese ancient medical practitioners about them. Results show that the right- or left-ward twirling of needles, gender, and needling at the right or left part, the front or the back part of the body of patients are not the core components of the reinforcing and reducing techniques.

[Summary and core technique on the origin and evolution of reinforcing-reducing manipulation achieved by lifting and thrusting the needle].

By analyzing the evolution of reinforcing-reducing manipulation achieved by lifting and thrusting the needle recorded in ancient literature of traditional Chinese medicine, it is found that the main contents of reinforcing-reducing manipulation by lifting and thrusting the needle include manipulating speed change, manual amplitude, insertion layer, gender, the direction to the acupuncture receiver, forenoon and afternoon and relevant quantity. Among them, gender, the direction to the acupuncture receiver, forenoon and afternoon and relevant quantity are the unnecessary parameters, while the manipulating speed change, manual amplitude and insertion layer are the indispensable parameters. The manipulating speed change is the core of the necessary parameters for the reinforcing-reducing manipulation achieved by lifting and thrusting the needle.

Proton-Conductive Cocrystals of Twin Isomers of Coordination Polymers in Situ Formed by Keggin Anions and Cu(II)-4,4'-Bis(hydroxymethyl)-2,2'-bipyridine Complex Moieties.

Cocrystals and isomers, two well-known unique concepts in supramolecular chemistry, are rarely put together until now. For the first time, we report three unprecedented and interesting cocrystals of twin isomers of coordination polymers (CPs) in situ formed by typical Keggin anions and Cu(II)-4,4'-bis(hydroxymethyl)-2,2'-bipyridine (Cu(II)-HL) complex moieties. In cocrystals 1-3, the Cu(II)-HL complex moieties are quadrisupported on Keggin-type anions through W(Mo)-Ot-Cu-Ot-W(Mo) (Ot is the terminal O atom) links in the crystal to form two twin ionic/neutral CPs with a fixed chemical stoichiometry.

[Evolvement of Acupuncture Needle Manipulation Techniques Described in Textbooks of Acupuncture and Moxibustion of Successive Editions].

This paper summarizes the evolvement of the needle manipulation techniques described in the textbooks of of the past successive 10 editions in Chinese, analyzes the reasons for the evolvement and its impact on clinical treatment, and proposes future developing trends. After analyzing characteristics of needle-manipulation techniques of the well-known Chinese acupuncture specialists, and those described in multi-editions of the textbooks, we found that the currently evoluted contents primarily contain the definition and types of manipulating techniques. However, the reasons for the evolvement and connotation of needle manipulating are probably due to a) undefined descriptions in the history; b) changes in the academic studies and clinical application of acupuncture and moxibustion during the textbook compilation; c) the well-known specialists' and the participated editors' academic thoughts; d) the textbook content setting needs, etc.
