[Summary of 's experience in treating refractory lateral epicondylitis with crescent technique of blade needle].

This paper introduces Professor 's clinical experience in treating refractory lateral epicondylitis using the 's crescent technique of blade needle. Based on the classical theories of () such as the "twelve sinew meridians" "short needling" and " needling", Professor applies a self-designed blade needle with crescent needling method. This approach forms a distinctive treatment philosophy characterized by "sinew meridians as the foundation, selecting points at the pain site; using chicken-claw needling technique deliverd at both internal and external; integration of heaven, earth, and man, using both short and needling; treating tendon injuries and inflammation with the crescent technique of blade needle".

Study on the migration characteristics of bioaerosols and optimization of ventilation patterns in a negative pressure isolation ward considering different patient postures.

Due to the serious global harm caused by the outbreak of various viral infectious diseases, how to improve indoor air quality and contain the spread of infectious bioaerosols has become a popular research subject. Negative pressure isolation ward is a key place to prevent the spread of aerosol particles. However, there is still limited knowledge available regarding airflow patterns and bioaerosol diffusion behavior in the ward, which is not conducive to reducing the risk of cross-infection between health care workers (HCWs) and patients.

SPINDOC binds PARP1 to facilitate PARylation.

SPINDOC is tightly associated with the histone H3K4me3 effector protein SPIN1. To gain a better understanding of the biological roles of SPINDOC, we identified its interacting proteins. Unexpectedly, SPINDOC forms two mutually exclusive protein complexes, one with SPIN1 and the other with PARP1.

Histone H3 N-terminal mimicry drives a novel network of methyl-effector interactions.

The reader ability of PHD fingers is largely limited to the recognition of the histone H3 N-terminal tail. Distinct subsets of PHDs bind either H3K4me3 (a transcriptional activator mark) or H3K4me0 (a transcriptional repressor state). Structural studies have identified common features among the different H3K4me3 effector PHDs, including (1) removal of the initiator methionine residue of H3 to prevent steric interference, (2) a groove where arginine-2 binds, and (3) an aromatic cage that engages methylated lysine-4.

Inhalation exposure to cigarette smoke and inflammatory agents induces epigenetic changes in the lung.

Smoking-related lung tumors are characterized by profound epigenetic changes including scrambled patterns of DNA methylation, deregulated histone acetylation, altered gene expression levels, distorted microRNA profiles, and a global loss of cytosine hydroxymethylation marks. Here, we employed an enhanced version of bisulfite sequencing (RRBS/oxRRBS) followed by next generation sequencing to separately map DNA epigenetic marks 5-methyl-dC and 5-hydroxymethyl-dC in genomic DNA isolated from lungs of A/J mice exposed whole-body to environmental cigarette smoke for 10 weeks. Exposure to cigarette smoke significantly affected the patterns of cytosine methylation and hydroxymethylation in the lungs.

Psychological effects of cognitive behavioral therapy on internet addiction in adolescents: A systematic review protocol.

Background: In this study, we aim to assess the psychological effects of cognitive behavioral therapy (CBT) on internet addiction (IA) in adolescents.

Methods: This study will search the following databases of Cochrane Library, PUBMED, EMBASE, Scopus, Web of Science, PsycINFO, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure. All these electronic databases will be searched from inception to the September 30, 2019 without any language limitation.

Crosstalk between Lys63- and Lys11-polyubiquitin signaling at DNA damage sites is driven by Cezanne.

The establishment of polyubiquitin conjugates with distinct linkages play important roles in the DNA damage response. Much remains unknown about the regulation of linkage-specific ubiquitin signaling at sites of DNA damage. Here we reveal that Cezanne (also known as Otud7B) deubiquitinating enzyme promotes the recruitment of Rap80/BRCA1-A complex by binding to Lys63-polyubiquitin and targeting Lys11-polyubiquitin.

Protein domain microarrays as a platform to decipher signaling pathways and the histone code.

Signal transduction is driven by protein interactions that are controlled by posttranslational modifications (PTM). Usually, protein domains are responsible for "reading" the PTM signal deposited on the interacting partners. Protein domain microarrays have been developed as a high throughput platform to facilitate the rapid identification of protein-protein interactions, and this approach has become broadly used in biomedical research.

The histone H3.3K36M mutation reprograms the epigenome of chondroblastomas.

More than 90% of chondroblastomas contain a heterozygous mutation replacing lysine-36 with methionine-36 (K36M) in the histone H3 variant H3.3. Here we show that H3K36 methylation is reduced globally in human chondroblastomas and in chondrocytes harboring the same genetic mutation, due to inhibition of at least two H3K36 methyltransferases, MMSET and SETD2, by the H3.

Site-Specific Identification of Lysine Acetylation Stoichiometries in Mammalian Cells.

Functional characterization of the lysine acetylation pathway requires quantitative measurement of the modification abundance at the stoichiometry level. Here, we developed a systematic workflow for global untargeted identification of site-specific Lys acetylation stoichiometries in mammalian cells. Our strategy includes an optimized protocol for in vitro chemical labeling of unmodified lysine with stable isotope-encoded acetyl-NHS ester, deep proteomic profiling with a high resolution mass spectrometer, and a new software tool for quantitative analysis and stoichiometry determination.

Thrombolytic and Antiplatelet Effects of a Novel Plasminogen Activator from the Venom of Gloydius Brevicaudus Viper.

Aim: To investigate the thrombolytic and antiplatelet effects of a novel plasminogen activator from the venom of the Gloydius brevicaudus viper (GBV-PA) in vitro and in vivo.

Methods: Thrombolytic experiments were performed in rabbit models of ear vein thrombosis and carotid artery thrombosis and in dog model of acute cerebral infarction. Inhibition of thrombus formation was evaluated in rat inferior vena cava thrombosis model and ferric chloride-induced arterial thrombosis.

Development of a model for predicting reaction rate constants of organic chemicals with ozone at different temperatures.

To assess the persistence and fate of volatile organic compounds in the troposphere, the rate constants for the reaction with ozone (kO3) are needed. As kO3 values are only available for hundreds of compounds, and experimental determination of kO3 is costly and time-consuming, it is of importance to develop predictive models on kO3. In this study, a total of 379 logkO3 values at different temperatures were used to develop and validate a model for the prediction of kO3, based on quantum chemical descriptors, Dragon descriptors and structural fragments.
