Migraine is one of the most prevalent and disabling neurological disease, but the current pharmacotherapies show limited efficacy and often accompanied by adverse effects. Acupuncture is a promising complementary therapy, but further clinical evidence is needed. The influence of acupuncture on migraine is not an immediate effect, and its mechanism remains unclear. This study aims to provide further clinical evidence for the anti-migraine effects of acupuncture and explore the mechanism involved. A randomized controlled trial was performed among 10 normal controls and 38 migraineurs. The migraineurs were divided into blank control, sham acupuncture, and acupuncture groups. Patients were subjected to two courses of treatment, and each treatment lasted for 5 days, with an interval of 1 day between the two courses. The effectiveness of treatment was evaluated using pain questionnaire. The functional magnetic resonance imaging (fMRI) data were analyzed for investigating brain changes induced by treatments. Blood plasma was collected for metabolomics and proteomics studies. Correlation and mediation analyses were performed to investigate the interaction between clinical, fMRI and omics changes. Results showed that acupuncture effectively relieved migraine symptoms in a way different from sham acupuncture in terms of curative effect, affected brain regions, and signaling pathways. The anti-migraine mechanism involves a complex network related to the regulation of the response to hypoxic stress, reversal of brain energy imbalance, and regulation of inflammation. The brain regions of migraineurs affected by acupuncture include the lingual gyrus, default mode network, and cerebellum. The effect of acupuncture on patients' metabolites/proteins may precede that of the brain.

Mistakenly picking and eating poisonous mushrooms can cause acute poisoning. In August 2020, Qingdao Hospital of Traditional Chinese Medicine handled a poisonous mushroom poisoning incident, conducted epidemiological investigation on all poisoned patients, collected suspicious food, clinical manifestations, clinical test results and treatment conditions, and identified the mushrooms as Amanita fuliginea poisoning after morphological identification. In this incident, 6 people ate grey goose paste, of which 4 were sick with a incubation period of 6~12 h. The clinical manifestations were gastrointestinal symptoms such as nausea, vomiting and diarrhea, liver and kidney damage. After symptomatic support treatment, hemoperfusion or continuous hemofiltration treatment, the patients were cured and discharged. It is suggested to strengthen the popular science education on poisonous mushroom poisoning and improve the ability of identification and clinical treatment of poisonous mushrooms in grass-roots medical institutions.

Bioactive peptides play important roles in promoting human health, such as lowering blood pressure, blood sugar and blood lipid, anti-obesity, and anti-cancer. Thus, exploring functional bioactive peptides and developing efficient production technologies are of crucial importance. Herein, we review the development of function discovery and production technology for natural bioactive peptides. Presently, the top-down and bottom-up approaches are mainly used for the function discovery and production of natural active peptides. The top-down approach includes the direct extraction and identification for functional discovery, and the direct extraction, enzymatic hydrolysis and microbial fermentation for production. The bottom-up approach includes the polypeptide modification and database mining for functional discovery, and the chemical synthesis, enzyme synthesis, recombinant expression and cell-free synthesis for production. The top-down approach is usually associated with complicated process, lower efficiency, higher cost, harder quality control, and uncertain functionality, while the bottom-up approach is more suitable for the development of peptide drugs but difficult to be used for functional foods. With the technology development of sequencing and mass spectrometry, it is easier to obtain the proteomic information of various organisms at the molecular level. Based on the proteomic information, the top-down and bottom-up approaches can be combined to overcome the disadvantages of using these two approaches alone, thus providing a new strategy for the rapid development and production of natural active peptides.

TANK-binding kinase 1 (TBK1), a core kinase of antiviral pathways, activates the production of interferons (IFNs). It has been reported that deacetylation activates TBK1; however, the precise mechanism still remains to be uncovered. We show here that during the early stage of viral infection, the acetylation of TBK1 was increased, and the acetylation of TBK1 at Lys241 enhanced the recruitment of IRF3 to TBK1. HDAC3 directly deacetylated TBK1 at Lys241 and Lys692, which resulted in the activation of TBK1. Deacetylation at Lys241 and Lys692 was critical for the kinase activity and dimerization of TBK1 respectively. Using knockout cell lines and transgenic mice, we confirmed that a HDAC3 null mutant exhibited enhanced susceptibility to viral challenge via impaired production of type I IFNs. Furthermore, activated TBK1 phosphorylated HDAC3, which promoted the deacetylation activity of HDAC3 and formed a feedback loop. In this study, we illustrated the roles the acetylated and deacetylated forms of TBK1 play in antiviral innate responses and clarified the post-translational modulations involved in the interaction between TBK1 and HDAC3.

Objective:To investigate the clinicopathological features and immunohistochemical phenotypes of hybrid oncocytic/chromophobe tumor (HOCT) of the kidney and its associations with renal oncocytoma (RO) and eosinophilic chromophobe renal cell carcinoma (eChRCC).Methods:A total of 8 HOCT cases were collected from 2008 to 2019 at the Affiliated Hospital of Qingdao University (5 cases) and 971 Hospital of PLA Navy (3 cases), Qingdao, China for morphological studies, immunohistochemical staining and follow-up. The immunohistochemical results of HOCT were compared with those of 27 typical RO and 17 eChRCC.Results:Among the 8 patients, 3 were male and 5 were female. Their ages ranged from 39 to 75 years (median: 56 years). All cases were sporadic. Seven patients were asymptomatic and one suffered from lumbago. During a mean follow-up of 37 months in 7 patients, none of them developed tumor recurrence or metastasis. Seven cases were solitary and one was multiple. The tumor size ranged from 1.4 to 5.7 cm (mean, 3.6 cm). The cut surface of the tumors was dark red or yellowish. Histologically, the tumors were well-defined. Six cases were directly adjacent to the surrounding renal tissue, 2 cases had pseudocapsule, 3 cases showed entrapped renal tubules at the edge of tumor tissue, and one circumscribed with focal infiltrating borders. There were two types of histological morphology: one type (4 cases) was composed of mixed areas of otherwise typical RO and areas resembling chromophobe renal cell carcinoma; another type (4 cases) showed the morphological characteristics of both RO and eChRCC. Three second-type tumors showed nest-like, trabecular, and solid growth patterns with conspicuous edematous stroma. The cell border was conspicuous and the cytoplasm showed an eosinophilic appearance. The nuclei were small and round with clear perinuclear halo. One tumor showed a multi-nodular and solid growth pattern, and the cytoplasm was eosinophilic, hypochromatic or transparent. The nuclei were small and round, and some of them had obvious perinuclear halo. Immunohistochemically, the tumor cells in all 8 cases were positive for Ksp-cad but negative for vimentin. CD117 was diffusely positive in 6/8 cases. CK7 staining showed patchy positivity in 6/8 cases. S-100A1, cyclin D1 and claudin7 showed variable positivity in 4/8, 6/8 and 5/8 cases, respectively, but the range and intensity were narrower and weaker than those in RO and eChRCC.Conclusions:HOCT is a low-grade eosinophilic renal tumor with morphological characteristics resembling RO and eChRCC. The combined application of immunohistochemical stains of CK7, CD117, Ksp-cad, cyclin D1, claudin7 and S-100A1 may play an auxiliary role in the differentiation of the three tumors. HOCT has a good prognosis after surgical resection and can be regarded as a tumor with uncertain malignant potential.

OBJECTIVE: To investigate the expression of CD123 in patients with acute myeloid leukemia (AML) and its relationship between clinical features, concomitant fusion gene or gene mutation, efficacy and prognosis. METHODS: 365 patients with newly diagnosed AML (except M3) treated in the First Affiliated Hospital of Zhengzhou University were enrolled and retrospective analysis, and multi-parameter flow cytometry was performed to detect the expression of CD123 in myeloid leukemia cell population. CD123≥20% was defined as positive. Clinical features, concomitant fusion gene or gene mutation, efficacy and prognosis of CD123 RESULTS: The positive rate of CD123 in 365 newly diagnosed AML patients was 38.9%. Compared with the CD123 CONCLUSION CD123 positive indicates that AML patients have higher tumor burden and are more difficult to reach remission. It is an independent risk factor for OS and EFS in patients with normal karyotype and intermediate risk, which is important to evaluate the prognosis of patients with AML without specific prognostic marker.
