ObjectiveTo investigate the mechanism of Xumingtang in Gu Jin Lu Yan (《古今录验》) in regulating cell pyroptosis through the hypoxia-inducible factor-1α (HIF-1α)/NOD-like receptor pyrin domain-containing protein 3 (NLRP3) pathway in ischemic stroke (IS). MethodSD rats were randomly divided into a sham operation group, a model group, low- and high-dose Xumingtang groups, and a metformin group, with 20 rats in each group. Oral administration was performed for 3 days, and tissue samples were collected. Differential messenger RNA (mRNA) was screened using high-throughput sequencing, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed on key differentially expressed genes. The modified neurological severity score (mNSS) and 2,3,5-triphenyltetrazolium chloride (TTC) staining were used to evaluate the effect of brain infarction. Hematoxylin-eosin (HE) staining was used for pathological morphological observation of brain tissue. Enzyme-linked immunosorbent assay (ELISA) was used to compare the levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) in the ischemic cortical region. Double staining immunohistochemistry was used to detect the co-localization of HIF-1α and NLRP3. Real-time quantitative polymerase chain reaction (PCR) was performed to detect the mRNA expression of NLRP3, HIF-1α, Caspase-1 (CASP-1), and gasdermin D (GSDMD). Western blot was used to detect the protein expression of HIF-1α, NLRP3, CASP-1, and GSDMD. ResultA total of 5 705 differentially expressed genes (2 733 downregulated and 2 972 upregulated) were obtained by mRNA sequencing. After conversion to homologous genes and intersection with the pyroptosis gene set, 95 key differentially expressed pyroptosis genes were obtained. Compared with the sham operation group, the model group showed significantly increased mNSS scores, larger brain infarction areas (P<0.01), diverse neuronal morphology, disordered arrangement, widened cell gaps, significantly increased levels of IL-1β and IL-18 in the ischemic cortical region (P<0.01), enhanced co-localization fluorescence intensity, and significantly increased mRNA and protein expression levels of HIF-1α, NLRP3, CASP-1, and GSDMD (P<0.01). Compared with the model group, the high-dose Xumingtang group showed the most significant improvement in neurological function scores and brain infarction areas (P<0.01). The neuronal integrity and arrangement were more complete, and the cell gaps were narrower in all groups with drug treatment, with significantly reduced co-localization fluorescence intensity. Xumingtang could reduce the levels of IL-1β, IL-18, and the mRNA and protein expression of HIF-1α, NLRP3, CASP-1, and GSDMD (P<0.05, P<0.01), with the high-dose Xumingtang group showing the most significant effect (P<0.01). ConclusionXumingtang in Gu Jin Lu Yan can inhibit cell pyroptosis and promote neurological function recovery after IS, which may be related to the inhibition of the HIF-1α/NLRP3 pathway.

This study was aimed at identifying the bioactive components of the crude and stir-baked hawthorn for invigorating spleen and promoting digestion, respectively, to clarify the processing mechanism of hawthorn by applying the partial least squares(PLS) algorithm to build the spectrum-effect relationship model. Firstly, different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions were prepared, respectively. Then, the contents of 24 chemical components were determined by ultra-high performance liquid chromatography-mass spectrometry. The effects of different polar fractions of crude hawthorn and stir-baked hawthorn aqueous extracts and combinations of different fractions were evaluated by measuring the gastric emptying rate and small intestinal propulsion rate. Finally, the PLS algorithm was used to establish the spectrum-effect relationship model. The results showed that there were significant differences in the contents of 24 chemical components for different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions, and the gastric emptying rate and small intestinal propulsion rate of model rats were improved by administration of different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions. The bioactive components of crude hawthorn identified by PLS models were vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, neochlorogenic acid, rutin, gallic acid, vanillic acid, citric acid, malic acid, quinic acid and fumaric acid, while neochlorogenic acid, cryptochlorogenic acid, rutin, gallic acid, vanillic acid, citric acid, quinic acid and fumaric acid were the bioactive components of stir-baked hawthorn. This study provided data support and scientific basis for identifying the bioactive components of crude and stir-baked hawthorn, and clarifying the processing mechanism of hawthorn.

In this paper, the low-field nuclear magnetic resonance technology CPMG (Carr-Purcell-Meiboom-Gill) echo method was used to determine the cross-linking degree and cross-linking density of crospovidone (PVPP) from different manufacturers. Based on the seven physical properties of PVPP, a fingerprint spectrum (radar chart) of twenty secondary quality indicators were obtained, and three compressibility evaluation indicators, index of the parameter (IP), index of parametric profile (IPP), index of good compression (IGC) were calculated by the fingerprint spectrum. It was found that the cross-linking degree and compressibility index IP of PVPP showed a strong correlation (r = 0.816) by the correlation analysis, indicating that the cross-linking degree is one of the key quality attributes for evaluating the compressibility of PVPP.

Mounting evidence has shown that exercise exerts extensive beneficial effects, including preventing and protecting against chronic diseases, through improving metabolism and other mechanisms. Recent studies have shown that exercise preconditioning affords significant cardioprotective effects. However, whether exercise preconditioning improves high fat diet (HFD)-induced obesity and lipid metabolic disorder remains unknown. The study was aimed to explore the effects of exercise preconditioning on HFD-induced obesity and lipid metabolic disorder in mice. 4-week-old C57BL/6 mice were subjected to swimming or sedentary control for 3 months, and then were fed with normal diet (ND) or HFD for 4 more months. The results showed that the blood glucose was decreased, and the glucose tolerance and grip strength were increased in exercised mice after training. Exercise preconditioning failed to improve HFD-induced body weight gain, but improved HFD-induced glucose intolerance. Exercise preconditioning showed no significant effects on both exercise capacity and physical activity in ND- and HFD-fed mice. HFD feeding increased total cholesterol and low density lipoprotein (LDL) levels in circulation, promoted subcutaneous fat and epididymal fat accumulation in mice. Exercise preconditioning increased circulating high density lipoprotein (HDL) and decreased circulating LDL, without affecting the subcutaneous fat and epididymal fat in HFD-fed mice. HFD feeding increased liver weight and hepatic total cholesterol contents, and dysregulated the expressions of several mitochondria function-related proteins in mice. These abnormalities were partially reversed by exercise preconditioning. Together, these results suggest that exercise preconditioning can partially reverse the HFD-induced lipid metabolic disorder and hepatic dysfunction, and these beneficial effects of exercise sustain for a period of time, even after exercise is discontinued.

The present study was designed to investigate the mechanisms by which P2X7 receptors (P2X7Rs) mediate the activation of vasopressinergic neurons thereby increasing sympathetic hyperactivity in the paraventricular nucleus (PVN) of the hypothalamus of rats with acute myocardial ischemia (AMI). The left anterior descending branch of the coronary artery was ligated to induce AMI in rats. The rats were pretreated with BBG (brilliant blue G, a P2X7R antagonist), nelivaptan (a vasopressin V1b receptor antagonist), or diphenyleneiodonium (DPI) [an nicotinamide adenine dinucleotide phosphate (NADPH) oxidase inhibitor]. Hemodynamic parameters of the heart were monitored. Myocardial injury and cardiomyocyte apoptosis were assessed. In the PVN of AMI rats, P2X7R mediated microglial activation, while reactive oxygen species (ROS) and NADPH oxidase 2 (NOX2) were higher than in the sham group. Intraperitoneal injection of BBG effectively reduced ROS production and vasopressin expression in the PVN of AMI rats. Moreover, both BBG and DPI pretreatment effectively reduced sympathetic hyperactivity and ameliorated AMI injury, as represented by reduced inflammation and apoptosis of cardiomyocytes. Furthermore, microinjection of nelivaptan into the PVN improved cardiac function and reduced the norepinephrine (AE) levels in AMI rats. Collectively, the results suggest that, within the PVN of AMI rats, P2X7R upregulation mediates microglial activation and the overproduction of ROS, which in turn activates vasopressinergic neuron-V1b receptors and sympathetic hyperactivity, hence aggravating myocardial injury in the AMI setting.

Objective:Postoperative venous obstruction (PVO) is the most severe complication of total anomalous pulmonary venous connection (TAPVC), and facing challenging re-intervention with high mortality. We aimed to review and analyze the follow-up and management of postoperative PVO in our center.Methods:We conducted a retrospective study of the patients with isolated TAPVC admitted in our center from October 2013 to October 2019. All available data and images of PVO patients were reviewed, such as the initial perioperative medical records, patients’ follow-up records, results of patients’ echo and CT angiography. Re-intervention including hybrid technique, sutureless technique, and patch augmentation, were carried out for postoperative PVO patients. The results were reviewed and analyzed to find the risk factors for adverse prognosis.Results:A series of 174 isolated TAPVC patients were admitted in our center and 169 received surgical treatment and 26 (26/169, 15.4%) had postoperative PVO. The diagnosis was made at a median time of 11.5 (0-77) weeks after initial operation and within 6 months of surgery in 22 (22/26, 84.6%) of the 26 patients. The subtype of TAPVC patients with postoperative PVO were: supracardiac 11 cases (11/26, 42.3%), cardiac 7 cases (7/26, 26.9%), infracardiac 5 cases (5/26, 19.2%), and mixed 3 cases (3/26, 11.5%). Bilateral obstruction and stenosis with diffusely small pulmonary veins were in 12 (12/26, 46.2%) and 3 cases (3/26, 11.5%) respectively. PVO progressed to worse condition in all the 26 cases during follow-up period. 8 (8/26, 30.8%) postoperative PVO patients underwent 10 re-interventions: one cases had 3 re-interventions. Five-year survival for patients with postoperative PVO was worse than those without postoperative PVO ( HR=6.46, 95% CI: 2.34-17.85, P<0.01). Risk factors for death or re-intervention in postoperative PVO patients were earlier presentation after TAPVC repair ( HR=0.85, 95% CI: 0.73-0.99, P=0.04) and an increased number of lung segments affected by obstruction ( HR=1.74, 95% CI: 1.01-2.99, P=0.04). Conclusion:Risk factors for death or re-intervention in postoperative PVO patients were earlier presentation after TAPVC repair and an increased number of lung segments affected, which should be focused on during strict follow-up period. Early re-intervention should be taken before irreversible secondary changes occur in these patients.

Objective To investigate the regulatory role of recombinant Trichinella spiralis cysteine protease inhibitors (rTs-Cys) in induction of polarization of bone marrow-derived macrophages (BMDMs) in vitro. Methods BMDMs were captured and cultured in conditioned medium for 7 days. Then, mature BMDMs were harvested and assigned into four groups. Cells in Group A (negative control) were given 10 ng/mL IFN-γ combined with 100 ng/mL LPS, cells in Group B (positive control) were treated with IL-4 and IL-10 (at 10 ng/mL both), and cells in Group C (recombinant protein alone) were stimulated with 1 μg/mL rTs-Cys, while cells in Group D (protein co-culture) were simultaneously treated with 1 μg/mL rTs-Cys, 10 ng/mL IFN-γ and 100 ng/mL LPS. Cells and culture supernatant were collected 24 hour post-treatment, and the proportions of F4/80+, CD11b+, CD206+ and CD11c+ cells were detected by flow cytometry. The levels of interleukin IL-6 (IL-6), tumor necrosis factor-α (TNF-α), IL-10 and transforming growth factor-β (TGF-β) in the cell culture supernatant were measured by ELISA and the CD86+ and CD206+ phenotypes were identified by immunofluorescent staining. Results Flow cytometry detected no significant difference in the proportion of F4/80+ CD11b+ CD11c+ cells among the four groups (F = 46.184, P < 0.001), and a lower proportion of F4/80+ CD11b+ CD11c+ cells was seen in groups C and D than in group A (all P values < 0.001). There was a significant difference in the proportion of F4/80+ CD11b+ CD206+ cells among the four groups (F = 11.032, P < 0.001), and a greater proportion of F4/80+ CD11b+ CD206+ cells was seen in groups C and D than in group A (all P values < 0.01). Immunofluorescent staining showed higher CD206+ expression and lower CD86+ expression in groups C and D than in Group A. There were significant differences in the IL-6 and (F = 3.950, P < 0.001) and TNF-α (F = 205.827, P < 0.001) levels in the cell culture supernatants among the four groups, and significantly lower IL-6 and TNF-α levels were measured in groups C and D than in Group A (both P < 0.05). There were significant differences in the IL-10 and (F = 8.274, P < 0.001) and TGF-β (F = 13.559, P < 0.01) levels in the cell culture supernatants among the four groups, and greater IL-10 and TGF-β levels were measured in Group C than in Group A (both P values < 0.01). In addition, the TGF-β level was significantly higher in Group D than in Group A (P < 0.05); however, there was no significant difference in the IL-10 level between groups D and A (P > 0.05). Conclusion rTs-Cys may induce the polarization of BMDMs to antiinflammatory M2 macrophages in vitro and inhibit the activation of M1 macrophages.

Anxiety disorders are a common mental illness that seriously endangered physical and mental health of human beings. The etiology of anxiety disorders is closely related to the abnormality of monoamines neurotransmitters, amino acids neurotransmitters and neuropeptides. The long-term use of anti-anxiety chemical drugs has some adverse effects, such as constipation, muscle relaxation, lethargy, tolerance and withdrawal symptoms. However, traditional Chinese medicines have advantages of multi-component, multi-target coordination, with less adverse reactions. Therefore, it is a promising prospect to develop novel anti-anxiety drugs from traditional Chinese medicines and formulas. This article reviewed some traditional Chinese medicines and formulas that can relieve anxiety symptoms. These include traditional Chinese medicines(Panax ginseng, Lycium ruthenium, Morus alba, Bupleurum plus dragon bone oyster soup, Chailong Jieyu Pills, and Naogongtai Formulas) with the effect on monoamine neurotransmitters, such as serotonin, dopamine, and norepinephrine; traditional Chinese medicines(Rehmannia glutinosa, Ziziphus jujuba Mill. var. spinosa, Jielv Anshen Decoction, Baixiangdan Capsules, Antianxietic Compound Prescription Capsules) with the effect on amino acid neurotransmitters, such as glutamic acid, γ-aminobutyrc acid; and traditional Chinese medicines(P. ginseng, Xiaoyao San, Shuyu Ningxin Decoction)with the effect on neuropeptide Y pathway, with the aim to provide theoretical basis for the further development of some novel and more effective anti-anxiety therapeutics from traditional Chinese medicine and formulas.

Objective To investigate the expression and clinical significance of transcription factor SOX5 in peripheral blood mononuclear cells (PBMCs) and serum in patients with rheumatoid arthritis (RA). Methods The relative expression of representative genes of the SOX gene family in the PBMCs from RA patients were detected by Real-Time Polymerase Chain Reaction (RT-PCR), and serum levels of SOX5 expression were measured by enzyme-linked immunosorbent assay (ELISA) in 30 RA patients, 27 osteoarthritis (OA) patients and 30 healthy controls (HC). The expression levels of SOX5 in PBMCs were detected by RT-PCR after stimulated with IL-6, TNF-α, IL-1β and IL-17 for 24 hours. The relationship between SOX5 and receptor activator of nuclear factor κB ligand (RANKL) was detected by co-Immunoprecipitation (co-IP). The formation of TRAP-positive cells after silence SOX5 in osteoclast precursor cell treated with RANKL was observed by Tartrate-resistant acid phasphate stain (TRAP). The differences were tested using one-way ANOVA followed by Student-Newman-Keuls post hoc analysis Correlations were analyzed using Pearson's analysis. Results SOX5 was predominantly expressed in the PBMCs of RA as compared with other SOX family genes in PBMC. PBMC levels of SOX5 in RA patients (21±19) were higher than the OA patients (10±8) and healthy control group (5±4)(F=8.343, P<0.01). While, Serum levels of SOX5 in RA patients [(19132±12054) pg/ml were higher than the OA patients [(9065±15172) pg/ml] and healthy control group [(3242±1251) pg/ml] (F=15.31, P<0.01). IL-6, TNF-α, IL-1β and IL-17 led to the up-regulation of SOX5 expression in PBMCs. IL-6, TNF-α, IL-1β promoted the interaction of SOX5 and RANKL in PBMCs. Silencing SOX5 reduced the formation of TRAP-positive cells in osteoclast precursor cell treated with RANKL. Conclusion Our results have proven that transcriptional factor SOX5 regulates the expression of RANKL and participates in the process of RA bone erosion. Inhibition of SOX5 expression may be a new therapy target of RA.
