BACKGROUND:Cardiac hypertrophy is an adaptive response of the heart to physiological and pathological stimuli such as pressure overload.It is of compensatory significance in the early stage,but if the stimulation continues,it can cause cardiomyopathy leading to heart failure.MicroRNAs are involved in the regulation of cardiac hypertrophy.However,the role of miR-20a in pressure overload-induced cardiac hypertrophy has not been reported. OBJECTIVE:To investigate the role of miR-20a in pressure overload-induced cardiac hypertrophy and the underlying mechanisms. METHODS:Transverse aortic constriction was used to induce cardiac hypertrophy in vivo and angiotensin Ⅱ was used to induce H9c2 cell models of cardiac hypertrophy in vitro.MiR-20a was overexpressed in vivo by intramyocardial injection of miR-20a overexpressing adenovirus and in vitro by transfecting miR-20a mimic into H9c2 cells.Cardiac hypertrophy was assessed by measuring heart weight/body weight ratio,cell surface area,and myocardial fibrosis.The expression levels of atrial natriuretic peptide,brain natriuretic peptide,β-myosin heavy chain and miR-20a were detected by real-time fluorescence quantitative PCR.Mitochondrial fission was detected by MitoTracker.The downstream target genes of miR-20a were predicted by RNAhybrid software. RESULTS AND CONCLUSION:(1)The expression level of miR-20a was significantly decreased in both hypertrophic cardiomyocytes and hearts(P<0.05).(2)At the animal level,overexpression of miR-20a significantly inhibited transverse aortic constriction-induced cardiac hypertrophy,including decreasing the upregulated expression level of hypertrophic marker genes(P<0.05),reduced the enlarged heart volume,reducing the increased heart weight/body weight ratio(P<0.01),reducing the increased myocardial cross-sectional area(P<0.05),and attenuating fibrosis(P<0.01).(3)At the cellular level,overexpression of miR-20a significantly inhibited angiotensin Ⅱ-induced cardiomyocyte hypertrophy,including decreasing the upregulated expression levels of atrial natriuretic peptide(P<0.05),brain natriuretic peptide(P<0.01)and β-myosin heavy chain(P<0.05),reducing the increased protein/DNA ratio(P<0.01),and suppressing the increased cell surface area(P<0.05).(4)Overexpression of miR-20a significantly inhibited angiotensin Ⅱ-induced mitochondrial fission(P<0.05).(5)The results of RNAhybrid software analysis showed that miR-20a and the mRNA 3'untranslated region of cAMP-dependent protein kinase inhibitor alpha were well complementary and the predicted binding sites were highly conserved.(6)In conclusion,miR-20a is significantly down-regulated in pressure overload-induced cardiac hypertrophy.Overexpression of miR-20a inhibits cardiac hypertrophy at both the cellular level and animal level and attenuates angiotensin Ⅱ-induced mitochondrial fission.

ObjectiveTo evaluate the effectiveness of Lutongning granules in the treatment of trigeminal neuralgia in animal models and study its mechanism of action, so as to provide laboratory data support for the clinical application of Lutongning granules and precise treatment. MethodMale SD rats were randomly divided into normal group, model group, carbamazepine group (0.06 g·kg-1·d-1), high-dose Lutongning group (2.70 g·kg-1·d-1), and low-dose Lutongning group (1.35 g·kg-1·d-1) according to the stratified basic mechanical pain thresholds, with 10 rats in each group. A trigeminal neuralgia model of rats was prepared by injecting 30% talc suspension into the infraorbital foramen area of the rat. The drug groups were administered 10 mL·kg-1 of drugs by gavage after 2 h of modeling. The normal group and the model group were administered distilled water by gavage under the same conditions once a day for 10 consecutive days. Von Frey brushes were used to determine the mechanical pain threshold of rats. A fully automated blood and body fluid analyzer was employed to detect the blood routine of rats. Hematoxylin and eosin (HE) staining was utilized to detect the pathological changes in the trigeminal ganglion and medulla oblongata tissue. Transmission electron microscopy was used to scan the ultrastructure of the medulla oblongata tissue. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of inflammatory factors interleukin (IL)-1, IL-6, IL-8, tumor necrosis factor (TNF)-α, neuropeptide substance P, and β-endorphins (β-EP) in the serum of rats, and Western blot was used to detect the protein expression levels of IL-1β, purinergic receptor P2X7 (P2X7R), and phosphorylated p38 mitogen-activated protein kinase (p-p38 MAPK). ResultCompared with that in the normal group, the pain threshold of rats in the model group was significantly lower (P<0.01). The absolute value of neutrophils (NEUT#) and the percentage of neutrophils (NEUT) were significantly improved, and the percentage of lymphocytes (LYMPH) was significantly reduced (P<0.01). The serum levels of IL-1, IL-6, IL-8, and TNF-α were significantly increased (P<0.01). SP content in brain tissue was significantly increased, and β-EP content was significantly decreased (P<0.01). The relative protein expression of IL-1β, P2X7R, and p-p38 MAPK was significantly increased (P<0.05). HE staining and transmission electron microscopy results of medulla oblongata tissue revealed neuronal degeneration, mild proliferation of microglial cells, reduction in the number of myelinated nerves, and obvious demyelination. The trigeminal nerve fibers of rats were disarranged, and some nerve fibers showed vacuolization. Axons were swollen, and Schwann cells proliferated. Demyelination was observed. Compared with the model group, each administration group significantly increased the pain threshold of rats (P<0.05, P<0.01), reduced NEUT# and NEUT, and elevated LYMPH (P<0.05, P<0.01). The administration group significantly decreased the levels of IL-1, IL-6, IL-8, and TNF-α in serum and SP in brain tissue (P<0.01) and increased the level of β-EP (P<0.01). They significantly down-regulated the protein expression of IL-1β, P2X7R, and p-p38 MAPK(P<0.05, P<0.01) and significantly ameliorated the pathological changes in medulla oblongata tissue and trigeminal nerves of rats. ConclusionLutongning Granules had significant therapeutic effects on trigeminal neuralgia induced by injection of talc into the infraorbital foramen of model rats, and the mechanism may be related to amelioration of P2X7R-mediated neuroinflammation and inhibition of demyelination of myelinated nerves.

Hepatocellular carcinoma is one of the most common malignant tumors worldwide, posing a great threat to human health and life. Despite the tremendous progress in understanding the origin and molecular characterization of hepatocellular carcinoma, there are still few therapeutic options that can significantly increase the survival rate and improve the quality of life of patients. Protein post-translational modifications (PTMs) are regulatory mechanisms for protein activity, localization, expression, and interactions with other cellular molecules that induce changes in protein properties and functions. More and more studies have demonstrated that PTMs and immunotherapy play an important role in the development of hepatocellular carcinoma, even in the immunosurveillance of hepatocellular carcinoma and the treatment and prognosis of hepatocellular carcinoma patients. Traditional types of PTMs include phosphorylation, glycosylation, methylation, and ubiquitination. Phosphorylation affects cancer development and progression by regulating tumor cell proliferation, invasion and metastasis, and inhibiting apoptosis. There are two main types of glycosylation: O-glycosylation andN-glycosylation. Abnormal glycosylation not only promotes the proliferation and metastasis of hepatocellular carcinoma cells, but also plays an important role in immune recognition and immune escape. Common methylation modifications include DNA methylation, RNA methylation and histone methylation. Among them, histone methylation, as an important epigenetic regulatory mechanism, is of great theoretical and practical significance for understanding the mechanism of hepatocellular carcinoma as well as carrying out the corresponding prevention and immunotherapy. Ubiquitination plays an important role in the localization, metabolism, function, regulation and degradation of proteins, and it is regulated at different levels by ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), ubiquitin-conjugating enzyme (E3), and a series of deubiquitinating enzymes (DUBs) and is closely related to hepatocellular carcinoma immunotherapy. This paper begins with a brief overview of the importance of PTMs of proteins, discusses the importance of these traditional types of PTMs in hepatocellular carcinoma immunotherapy, and summarizes the most recent applications of these approaches in hepatocellular carcinoma in order to explore the mechanism of action of PTMs in hepatocellular carcinoma immunotherapy. Then, we summarize the finding that programmed death-ligand 1 (PD-L1) is associated with a variety of conventional types of PTMs, that in-depth study of the mechanisms regulating PD-L1 expression in tumor cells is expected to improve therapeutic efficacy, and that targeting PD-L1 in PTMs is expected to be a new field for exploring hepatocellular carcinoma immunotherapy in the future. Finally, we discuss the current status of research on PTMs for hepatocellular carcinoma immunotherapy and provide new insights and future research directions. In addition to the traditional types of PTMs, multiple novel PTMs have also been identified in published research reports, while the relationship between novel PTMs and hepatocellular carcinoma and the types of PTMs to other undiscovered proteins are still poorly understood, and future research will be focused on a more comprehensive knowledge and understanding of PTMs as well as on exploring new types and mechanisms of PTMs. Overall, further investigation of the role of PTMs in tumor immunity could help to discover new biomarkers and to develop more effective and personalized cancer immunotherapies and targeted therapies, expanding our understanding of cancer biology.

ObjectiveTo adapt the Stanford Expectations of Treatment Scale(SETS) into Chinese(C-SETS) and test the feasibility, validity and reliability of its application in patients with diarrhea-predominant irritable bowel syndrome(IBS-D) with liver-constraint and spleen-deficiency syndrome treated with traditional Chinese medicine(TCM). MethodsWe obtained authorisation from the developer of the SETS, and followed the principle of "two-way translation" to translate the SETS by literal translation and back translation to form the C-SETS. Ninety-six IBS-D patients with liver-constraint and spleen-deficiency syndrome were enrolled as respondents and filled out C-SETS before receiving treatment; the feasibility was assessed by the recall rate, completion rate and the duration of filling out the scale; the reliability was assessed by Cronbach's α; the structural validity was assessed by exploratory and confirmatory factor analysis, and the content validity was assessed by correlation analysis. ResultsThe C-SETS consists of 10 items, with the 1st, 3rd, and 5th rating items constituting the Positive Expectations subscale, and the 2nd, 4th, and 6th rating items constituting the Negative Expectations subscale, each of which is rated on a 7-point Likert Scale. The recall of C-SETS was 100%(96/96), the completion rate was 89.58%(86/96); Cronbach's α for the Positive and Negative Treatment Expectations subscales were 0.845 and 0.854, respectively; exploratory factor analysis showed that the coefficient of commonality for all six entries was larger than 0.4, and that the six entries could be used by both factors to explain 77.092% of the total variance; validation factor analysis showed that the goodness-of-fit index, comparative fit index, root mean square of approximation error, canonical fit coefficient, and chi-square degrees of freedom ratio took the values of 0.943, 1.003, 0, 0.943, and 0.626, respectively; and the results of Spearman's analysis suggested that the C-SETS had good content validity. ConclusionThe C-SETS has well feasibility, reliability, and validity, which initially proves that it can be used as a tool to assess the treatment expectation of patients with IBS-D with liver-constraint and spleen-deficiency syndrome before receiving TCM treatment.
