Objective: To investigate the effects and clinical significance of NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome activated by interleukin (IL)-17A in chronic rhinosinusitis with nasal polyps (CRSwNP). Methods: Patients underwent nasal endoscopic surgery in the Third Affiliated Hospital of Sun Yat-sen University from January 2020 to December 2021 were collected, including 28 CRSwNP (including 19 males and 9 females, aged 19 to 67 years), 22 chronic rhinosinusitis without nasal polyps (CRSsNP) and 22 controls. qRT-PCR was used to detect the expressions of IL-17A, NLRP3, IL-1β and IL-18 in the three groups, and their correlations were analyzed. The positions of IL-17A, NLRP3 and IL-18 in nasal polys were analyzed by immunofluorescence. Western Blotting and ELISA were employed to detect the expression of NLRP3, IL-1β and IL-18 in the human nasal epithelial cells after using IL-17A stimulation or IL-17A receptor inhibitor. Immunofluorescence was used to observe the NLRP3, IL-1β, and IL-18 protein expression after IL-17A stimulating human nasal epithelial cells, and after the use of IL-17A receptor inhibitor and NLRP3 inhibitor MCC950. The correlations between NLRP3, IL-1β, IL-18 and CT scores, nasal endoscopic scores, visual analogue scale (VAS) scores, and sino-nasal outcome test (SNOT) 22 scores of CRSwNP patients were analyzed. SPSS 20.0 software was used for statistical analysis. Results: The expressions of IL-17A, NLRP3, IL-1β and IL-18 in the tissues of CRSwNP patients were significantly higher than those in CRSsNP group(P=0.018,P<0.001,P=0.005, P=0.016) and the control group(all P<0.001). IL-17A was positively correlated with the expression of NLRP3, IL-1β, and IL-18(r ralue was 0.643,0.650,0.629,respectively, all P<0.05). IL-17A, NLRP3, and IL-18 were co-localized in the epithelial propria of polyp tissue. IL-17A stimulated the expressions of NLRP3, IL-1β, and IL-18 in human nasal epithelial cells. After the use of IL-17A receptor inhibitor, the expressions of NLRP3, IL-1β, and IL-18 were significantly down-regulated. After the use of NLRP3 inhibitor MCC950, IL-17A was significantly down-regulated to promote the expression of NLRP3, IL-1β, and IL-18. The expressions of NLRP3, IL-1β and IL-18 were positively correlated with CT, nasal endoscopy, VAS, and SNOT22 scores in patients with CRSwNP. Conclusions: IL-17A promotes the release of IL-1β and IL-18 by activating the NLRP3 inflammasome and aggravates the severity of the disease in CRSwNP.

ObjectiveTo observe the effects of modified Chaihu Shugansan(CHSG) and its disassembled formulas on angiotensin-converting enzyme 2 (ACE2)-angiotensin (Ⅰ-Ⅶ) [Ang (Ⅰ-Ⅶ)]-mitochondrial assembly receptor (MasR) axis in hyperlipidemic rats with myocardial ischemia and depression, and to explore the underlying mechanism of its prevention and treatment of myocardial ischemia and depression. MethodA total of 108 male SD rats were randomly divided into a normal group, a model group, a modified CHSG group (11.7 g·kg-1), a Quyu Huatan disassembled formula group (4.05 g·kg-1), a Shugan Xingqi disassembled formula group (3.15 g·kg-1), a Jianpi Yangxue disassembled formula group (4.5 g·kg-1), a fluoxetine group (0.001 8 g·kg-1), a trimetazidine group (0.005 4 g·kg-1), and a simvastatin group (0.001 8 g·kg-1), with 12 rats in each group. The hyperlipidemia model with myocardial ischemia and depression was induced with a high-fat diet combined with injection of isoproterenol (ISO) and chronic unpredictable mild stress (CUMS) in rats in the model group and groups with drug intervention for eight weeks. The rats in each group with drug intervention were treated correspondingly by gavage from the first day of modeling, while those in the normal group and the model group received the same amount of normal saline. The behavioral changes of rats in each group were observed by open field test and forced swimming test. Left ventricular fractional shortening (LVFS) and left ventricular ejection fraction (LVEF) were measured by echocardiography. The serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were detected by the enzyme-labeled apparatus. Hematoxylin-eosin (HE) staining was used to observe the histomorphological changes of the heart. The serum levels of angiotensin Ⅱ (AngⅡ), ACE2, and Ang(Ⅰ-Ⅶ) were detected by enzyme-linked immunosorbent assay (ELISA). The protein and mRNA expression of ACE2 and MasR in the hippocampus and the heart was detected by real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultCompared with the normal group, the model group showed reduced movement time, distance, and average speed in the central area of the open field (P<0.01), prolonged immobility time of rats in the forced swimming test (P<0.01), decreased LVFS and LVEF (P<0.01), inflammatory exudation and disorderly arranged fiber in heart tissues, elevated serum levels of TC, LDL-C, AngⅡ, ACE2 and Ang(Ⅰ-Ⅶ), diminished HDL-C (P<0.01), dwindled mRNA and protein expression of ACE2 in the hippocampus and the heart and MasR in the hippocampus, and up-regulated mRNA and protein expression of MasR in the heart (P<0.01). Compared with the model group, the modified CHSG group displayed increased movement time, distance, and average speed in the center area of the open field (P<0.01), shortened immobility time in the forced swimming test (P<0.01), increased LVFS and LVEF (P<0.01), relieved heart injury, reduced serum levels of TC, LDL-C, AngⅡ, ACE2, and Ang(Ⅰ-Ⅶ), elevated level of HDL-C (P<0.01), up-regulated mRNA and protein expression of ACE2 in the hippocampus and the heart and MasR in the hippocampus, and down-regulated mRNA and protein expression of MasR in the heart (P<0.01). Each disassembled formula could improve the above indexes to a certain extent (P<0.05, P<0.01), but the effect of the whole formula was optimal. ConclusionThe modified CHSG and its disassembled formulas have the effects of resisting depression, improving myocardial injury, and reducing blood lipid. Due to the synergistic effects of stasis-resolving/phlegm-eliminating drugs, liver-smoothing/Qi-moving drugs, and spleen-tonifying/blood-nourishing drugs in the formula, the modified CHSG is superior to each disassembled formula in efficacy. Its mechanism may be related to the activation of the ACE2-Ang (Ⅰ-Ⅶ)-MasR axis.

The human UDP-glucuronosyltransferase 1A1 (UGT1A1), one of the most essential conjugative enzymes, is responsible for the metabolism and detoxification of bilirubin and other endogenous substances, as well as many different xenobiotic compounds. Deciphering UGT1A1 relevance to human diseases and characterizing the effects of small molecules on the activities of UGT1A1 requires reliable tools for probing the function of this key enzyme in complex biological matrices. Herein, an easy-to-use assay for highly-selective and sensitive monitoring of UGT1A1 activities in various biological matrices, using liquid chromatography with fluorescence detection (LC-FD), has been developed and validated. The newly developed LC-FD based assay has been confirmed in terms of sensitivity, specificity, precision, quanti-tative linear range and stability. One of its main advantages is lowering the limits of detection and quantification by about 100-fold in comparison to the previous assay that used the same probe substrate, enabling reliable quantification of lower amounts of active enzyme than any other method. The precision test demonstrated that both intra- and inter-day variations for this assay were less than 5.5%. Further-more, the newly developed assay has also been successfully used to screen and characterize the regu-latory effects of small molecules on the expression level of UGT1A1 in living cells. Overall, an easy-to-use LC-FD based assay has been developed for ultra-sensitive UGT1A1 activities measurements in various biological systems, providing an inexpensive and practical approach for exploring the role of UGT1A1 in human diseases, interactions with xenobiotics, and characterization modulatory effects of small mole-cules on this conjugative enzyme.

Objective: To investigate the mid-and long-term clinical effects of tricuspid valvuloplasty with the implantation of an artificial plastic ring. Methods: Data of 677 patients who had functional tricuspid regurgitation and left cardiac valve disease and underwent tricuspid valvuloplasty and left cardiac valve surgery were retrospectively. Among these patients, 353 underwent simple suture annuloplasty (group A) while the rest 324 patients underwent artificial plastic ring annuloplasty (group B). The two-year and more-than-two-year clinical and ultrasonocardiograph (UCG) follow-up data of the two groups were obtained and compared. Results: A total of 600 patients (88.6%) completed the long-term follow-up (more than two years). The two-year follow-up showed no significant difference in the incidence of mild tricuspid regurgitation between the two groups (82.2% vs. 92.7%, P=0.37). However, there were significantly more cases that developed into moderate to severe tricuspid regurgitation in group A than in group B (17.8% vs. 7.3%, P=0.031). The long-term follow-up revealed that the recurrence rate of tricuspid regurgitation in group B was significantly lower than that in group A (11.0% vs. 25.0%, P=0.029), and the ratio of cases developing into moderate to severe tricuspid regurgitation in group A was significantly higher than that in group B (28.9% vs. 9.9%, P=0.007). The comparison between the two intra-group time segments showed that the development of tricuspid regurgitation in group A was significantly increased (28.9% vs. 17.8%, P=0.022), but in group B it was relatively stable (9.9% vs. 7.3%, P=0.52). Conclusions: Artificial ring annuloplasty is associated with significantly less tricuspid regurgitation than simple suture annuloplasty.

High-density lipoprotein (HDL), an abundant plasma lipoprotein, has been thought to be anti-inflammatory in both health and infectious diseases. It binds lipopolysaccharide (LPS) and neutralizes its bioactivity. The present study aimed to investigate the potential role of HDL, which was separated from human plasma, in LPS-induced acute lung injury in mice. Kunming mice (18-22 g) were treated with either HDL (70 mg/kg body weight, via tail vein) or saline 30 min after LPS administration (10 mg/kg body weight, intraperitoneally) and were decapitated 6 h after LPS challenge. The arterial blood was collected and analyzed for blood gas variables (PaO(2), pH, and PaCO(2)). The bronchoalveolar lavage fluid (BALF) samples were analyzed for total protein concentration, lactate dehydrogenase (LDH) activity, and white blood cell (WBC) count. The lung samples were taken for histopathological evaluation and for determination of lung wet-to-dry weight ratio (W/D), malondialdehyde (MDA) content, myeloperoxidase (MPO) activity and tumor necrosis factor α (TNF-α) content. Arterial blood gas analysis showed that after LPS challenge, HDL-treated mice exhibited a higher PaO(2), and pH, but a lower PaCO(2) than HDL-untreated ones (P<0.01). LPS-induced increases in total protein concentration, WBC number and LDH activity in BALF were significantly attenuated in HDL-treated mice (P<0.01). HDL treatment also resulted in a significant protection of lung tissues against LPS-induced acute lung injury via decreasing W/D ratio, MPO activity, MDA content, and the content of the pro-inflammatory cytokine TNF-α (P<0.05, P<0.01). Histological examination revealed that HDL treatment resulted in significantly lower scores of acute lung injury induced by LPS, with reduced hemorrhage, intra-alveolar edema and neutrophilic infiltration (P<0.01). It is suggested that HDL plays a protective role in attenuating LPS-induced acute lung injury in mice.
