This article was aimed to study the analgesic and antipyretic effect of Re-Du-Ning (RDN) Injection. Heating model was building on SD rats after subcutaneous injection of yeast. And then, RDN Injection was intravenous injected at the dose of 10.16 g·kg-1, 5.08 g·kg-1, and 2.54 g·kg-1, respectively. Observation was made on changes of rats' temperature. RDN Injection was intravenous injected into ICR mice at the dose of 20.30 g·kg-1, 10.15 g·kg-1, 5.08 g·kg-1 for 7 consecutive days. The methods of mice twist, hot plate and jaw pain were used in the testing of analgesic action of RDN Injection. The results showed that RDN Injection at high and middle dose can significantly reduce the temperature of heating rats models (P < 0.05 or P < 0.01). It can also significantly reduce the twisting times of mice by acetic acid (P< 0.05 or P< 0.01). It can also significantly increase the pain threshold of mice by hot plate and jaw pain (P< 0.05 or P< 0.01). It was concluded that RDN Injection had a good analgesic and antipyretic effect in mice.

ObjectiveTo investigate the therapeutic effect of Lycopi Herba extract on chronic prostatitis (CNP) and explore the underlying action mechanism via the inflammasome NOD-like receptor protein 3 (NLRP3) pathway. MethodNormal human prostatic stromal cells, namely WPMY-1 were induced by lipopolysaccharide (LPS) of 5 mg·L-1, and the effects of Lycopi Herba extract of 3.125, 6.25, 12.5, 25, 50, and 100 mg·L-1 on interleukin-6 (IL-6) level released by LPS-induced WPMY-1 cells were detected by enzyme-linked immunosorbent assay (ELISA). The half-maximal inhibitory concentration (IC50) was calculated. The expression of key proteins in the NLRP3 pathway was detected by western blot after Lycopi Herba extract of 50, 75, and 100 mg·L-1 was administered to WPMY-1 cells. The rat model of CNP was established by injecting carrageenan salt solution into the abdominal lobe of the prostate gland. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes in the prostate gland in rats. The prostate organ index of rats was measured. The level of 5α-dihydrotestosterone (5α-DHT) in serum, as well as the levels of IL-6, tumor necrosis factor-α (TNF-α), transforming growth factor-β1 (TGF-β1), cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE2), and inducible nitric oxide synthase (iNOS) in prostate tissue were detected by ELISA. The key protein expressions of COX-2, TGF-β1, and NLRP3 pathway in prostate tissue were detected by Western blot. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the expressions of COX-2, IL-1β, TGF-β1, and TNF-α mRNA in prostate tissue. ResultCompared with the normal group, the level of IL-6 and the protein expression levels of NLRP3, ASC, Caspase-1, and IL-1β of WPMY-1 cells in the model group were increased (P<0.05, P<0.01). Compared with the model group, Lycopi Herba extract could inhibit the levels of IL-6 (P<0.01) released by LPS-induced WPMY-1 cells, with IC50 of 38.26 mg·L-1. The protein expression levels of NLRP3, ASC, and IL-1β in the low-, medium-, and high-dose groups of Lycopi Herba extract were significantly down-regulated (P<0.05, P<0.01). The expression levels of Caspase-1 protein in medium- and high-dose groups of Lycopi Herba extract were significantly down-regulated (P<0.05, P<0.01). Compared with the sham operation group, the prostate organ index of rats in the model group was significantly increased (P<0.01), a large number of inflammatory cells were infiltrated in the prostate tissue, and the histopathological score was significantly increased (P<0.05); the levels of 5α-DHT in serum, the levels of TNF-α, PGE2, IL-6, TGF-β1, NOS2/iNOS, and COX-2 in prostate tissue, and expression levels of COX-2, IL-1β, and TGF-β1 were significantly increased (P<0.05, P<0.01). The mRNA expression levels of COX-2, TGF-β1, NLRP3, Caspase-1, ASC, and IL-1β in prostate tissue were significantly up-regulated (P<0.05, P<0.01). Compared with model group, the low and high doses of Lycopi Herba extract could alleviate the pathological changes in prostate tissue induced by carrageenan, significantly reduce the level of 5α-DHT in serum, levels of TNF-α, PGE2, TGF-β1, and iNOS in prostate tissue (P<0.05, P<0.01), and mRNA expression levels of COX-2, IL-1β, and TGF-β1 (P<0.05, P<0.01). The protein expression levels of COX-2, Caspase-1, ASC, and NLRP3 in prostate tissue were significantly down-regulated (P<0.05, P<0.01). The prostate organ index of the low-dose group of Lycopi Herba extract was significantly decreased (P<0.01). The level of COX-2 in prostate tissue of the high-dose group of Lycopi Herba extract was significantly decreased, and the protein expression levels of TGF-β1 and IL-1β were significantly down-regulated (P<0.05). ConclusionLycopi Herba extract has an obvious therapeutic effect on CNP and may reduce inflammation by inhibiting the activation of the inflammasome NLRP3 signaling pathway.

ObjectiveTo explore the efficacy and mechanism of the alcohol extract DH50 of Angelicae Pubescentis Radix in treating gouty arthritis induced by monosodium urate (MSU) crystals in vivo and in vitro. MethodFifty male SD rats were randomly assigned into five groups (n=10): a normal group, a model group, a dexamethasone (DXMS, 0.07 mg·kg-1) group, and low- (DH50-D, 9 mg·kg-1) and high-dose (DH50-G, 18 mg·kg-1) DH50 groups. The rats in the normal group and model group were administrated with the same amount of pure water. On day 5, the gouty arthritis model was established by injecting MSU into the right ankle joint of rats. The toe volume and joint inflammation index were measured 4, 8, 24, and 48 h after modeling. The pathological changes of the synovial tissue were detected by hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, and IL-6 in the synovial tissue. Western blot was employed to measure the protein levels of NOD-like receptor protein 3 (NLRP3), cysteine-aspartic protease-1 (Caspase-1), apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain (ASC), IL-1β, and cyclooxygenase-2 (COX-2) in the synovial tissue. Furthermore, the cell inflammation model was established with RAW264.7 cells stimulated with MSU (75 mg·L-1). The cell experiments were carried out with 6 groups: a normal group, a model group, a positive drug (DXMS, 100 μmol·L-1) group, and low- (DH50-D, 25 mg·L-1), medium- (DH50-Z, 50 mg·L-1), and high-dose (DH50-G, 100 mg·L-1) DH50 groups. Methyl thiazolyl tetrazolium (MTT) assay was employed to determine the cell viability, ELISA to determine the content of TNF-α in the supernatant of cell culture, and Western blot to determine the protein levels of NLRP3, cleaved Caspase-1, IL-1β, TNF-α, and COX-2. ResultCompared with the normal group, the rat model group showed increased toe swelling degree and joint inflammatory index (P<0.01), serious infiltration of the synovium, elevated levels of inflammatory cytokines in the tissue homogenate (P<0.01), and up-regulated protein levels of NLRP3, Caspase-1, ASC, IL-1β, and COX-2 (P<0.05, P<0.01). Compared with the rat model group, low- and high-dose DH50 mitigated the toe swelling degree, decreased the joint inflammatory index, alleviated the inflammatory infiltration, lowered the levels of inflammatory cytokines in the tissue homogenate (P<0.01), and down-regulated the expression of related proteins (P<0.05, P<0.01). Compared with the normal group, the cell model group showed elevated level of TNF-α in the supernatant (P<0.01) and up-regulated protein levels of NLRP3, cleaved Caspase-1, IL-1β, TNF-α, and COX-2 (P<0.05). Compared with the model group, low, medium, and high doses of DH50 lowered the level of TNF-α in the supernatant of cell culture in a dose-dependent manner and down-regulated the expression of related proteins (P<0.05, P<0.01). ConclusionDH50 can mitigate gouty arthritis both in vitro and in vivo by inhibiting the activation of NLRP3 inflammasomes and the production of inflammatory cytokines.

ObjectiveTo investigate the effect of alcohol extract of Oroxylum indicum (MHD-80) on reducing uric acid (UA) and protecting the kidney in the hyperuricemia (HUA) model in vivo. MethodPotassium oxazine (350 mg·kg-1) and adenine (80 mg·kg-1) were used to construct an HUA model of mice in vivo to evaluate the mechanism related to UA reduction and the protective effect of renal function of MHD-80. Seventy male ICR mice were randomly divided into seven groups, including the normal group, model group, allopurinol group (5 mg·kg-1), febusotan group (5 mg·kg-1), and MHD-80 low-, medium-, and high-dose groups (3, 6, 12 mg·kg-1), with 10 in each group. Except for the normal group, the other groups were given intragastric administration of potassium oxazine and adenine for 14 consecutive days to establish the HUA model. On the 8th to 14th day after modeling, each group was given corresponding drugs by intragastric administration, once a day. 1 h after the last administration, blood was collected from the eyeballs, and kidney and liver tissues of mice were collected. Serum levels of UA, urea nitrogen (BUN), and creatinine (Cr) and liver activity of xanthine oxidase (XOD) were determined by enzyme colorimetry. Serum contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were determined by enzyme-linked immunosorbent assay (ELISA). Hematoxilin-eosin (HE) staining was used to observe the pathological changes in kidney tissues. The protein expression levels of ATP-binding box transporter G2 (ABCG2) and glucose-facilitating transporter 9 (GLUT9) in kidney tissues were detected by Western blot. ResultIn vivo experiment shows that compared with the normal group, the serum levels of UA, Cr, BUN, inflammatory factors TNF-α, IL-1β, and liver XOD activity in the serum of mice in the model group were significantly increased (P<0.05, P<0.01), and the expression of GLUT9 in kidney tissues was significantly up-regulated (P<0.05). ABCG2 protein expression was significantly down-regulated (P<0.05), and renal injury was obvious. Compared with the model group, the levels of UA, BUN, Cr, TNF-α, IL-1β, and liver XOD activity in the serum of mice in the high-dose group of MHD-80 were decreased to different degrees (P<0.05, P<0.01), GLUT9 protein expression was significantly down-regulated (P<0.01), ABCG2 protein expression was significantly up-regulated (P<0.05) in the high-dose group of MHD-80, and the degree of renal injury was reduced. ConclusionMHD-80 has certain uric acid reduction, anti-inflammatory, and anti-renal injury effects, which are related to inhibiting XOD activity and regulating the expression of ABCG2 and GLUT9 uric acid transporter.

OBJECTIVETo observe the clinical and biological characteristics of Non-IgM-secreting lymphoplasmacytic lymphoma (LPL) and draw the differences between non-IgM LPL and Waldenström macroglobulinemia (WM).
METHODSRecords of 13 patients with non-IgM LPL were retrospectively analyzed between January 2000 and December 2013. The cytogenetic aberrations were detected by fluorescence in situ hybridisation (FISH).
RESULTSIn the cohort, 7 males and 6 females with a median age of 63 years (range 43 to 74), two patients were IgA secreting, 6 with IgG secreting and 5 patients without monoclonal globulin. The major complaint at diagnosis included anemia associated symptom (53.8%), mucocutaneous hemorrhage and superficial lymphadenopathy (15.4%). Eight patients had B symptom at diagnosis. All of the 13 patients had bone marrow involvement and anemia, and 10 patients had 2 or 3 lineage cytopenia. In 5 patients with available immunophenotypic data, all expressed CD19, CD20, CD22 and CD25, but missed the expression of CD10, CD103 and CD38. Two cases had CD5 or sIgM positive alone. Another 2 patients were CD23 or CD11c positive and 3 patients were FMC7 positive. Cytogenetic aberrations had been detected by FISH in 7 patients, but only two (28.6%) patients had aberrations with del(6q).
CONCLUSIONThe clinical and biological characteristics had no significantly difference between non-IgM LPL and WM.
