Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease categorized by infiltration of inflammatory cells, synovial hyperplasia, pannus formation and bone destruction, leading to disability worldwide. Despite the presence of the commercial availability of anti-RA agent on the market, the application of these drugs is limited due to its side effects. Anti-rheumatic drugs are more effective and safer being investigated by many researchers, especially, natural products with anti-RA have been identified and the underlying molecular mechanisms of action of novel and known compounds have been reported. In this review, we intend to provide a comprehensive view and updated on naturally occurring compounds known and novel that has the effect of anti-RA, and then classify them according to their molecular mechanisms of action in regulating the anti-RA lane main. The safety of compounds from natural plants and western medicine has also been briefly compared. In addition, the clinical trials with anti-RA compounds isolated from natural plants in RA were also summarized in this manuscript.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by failure of spontaneous resolution of inflammation. The stem of Kadsura heteroclite (KHS) is a well-known anti-arthritic Tujia ethnomedicinal plant, which named Xuetong in folk, has long been used for the prevention and treatment of rheumatic and arthritic diseases. AIM OF THE STUDY The analgesic and anti-inflammatory effects and the potential mechanisms behind such effects of KHS would be investigated by using different animal models. MATERIALS AND METHODS The abdominal writhing episodes of mice induced by intraperitoneal injection of acetic acid and the tail-flick response induced by radiant heat stimulation were used to evaluate the analgesic effect of KHS. The number of abdominal writhing episodes of mice and the latency of tail-flick in rats were measured and recorded. In acute inflammatory models, the ear edema of mice was induced by applying xylene on the ear surface, while the paw edema of male and female rats was induced by subcutaneous injection of carrageenan into the right hind paws of animals. The carrageenan-induced paw swelling in rats were selected as an anti-acute inflammatory mechanism of KHS. Serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor (TNF-α) were measured by ELISA, and protein expression of cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) were detected by Western blot. RESULTS The maximal tolerated single dose of KHS was determined to be 26 g/kg in both sexes of mice. Pharmacological studies showed that KHS at the dose of 200 mg/kg significantly prolonged the reaction time of rats to radiant heat stimulation and suppressed abdominal writhing episodes of mice induced by intraperitoneal injection of acetic acid. KHS at the dose of 200, 400, and 800 mg/kg, showed dose-dependent inhibition of xylene-induced ear swelling in mice. KHS at the dose of 100, 200, 400, and 800 mg/kg demonstrated dose- and time-dependent suppression of paw edema induced by subcutaneous injection of carrageenan in both all rats. Mechanistic studies revealed that the anti-inflammatory effect of KHS was associated with inhibition of the production of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α and effectively decreased the expression of COX and iNOS proteins in the carrageenan-injected rat serum, paw tissues and inflammatory exudates. The positive reference drug, rotundine at a dosage of 100 mg/kg and indomethacin at a dosage of 10 mg/kg were used in both mice and rat models. CONCLUSION These results suggested that KHS has significant effects on analgesia and anti-inflammation with decreasing the pro-inflammation cytokines of IL-1β, IL-6, and TNF-α and inhibiting the proteins expression of COX-2 and iNOS.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic autoimmune diseased state, characterized by hyperplasia of the synovial membrane, degradation of cartilage, and bone erosion of diarthrodial joints. Kadsura heteroclita (Roxb) Craib (Schizandraceae), a traditional Tujia ethnomedicine called Xue Tong in China, has been long used for the prevention and treatment of rheumatic and arthritic diseases, especially in the southern China. This study aimed to evaluate anti-arthritic effects of the ethanol extract of Kadsura heteroclita stems (KHS) on complete Freund's adjuvant (CFA)-induced arthritis (AIA) in rats, as well as to explore the underlying mechanisms of anti-arthritis. METHODS AIA was established in male Sprague-Dawley (SD) rats as described previously, and animals were daily treated by gavage with KHS ethanol extract (200, 400, or 800 mg/kg) or vehicle (0.3% CMCNa) throughout the 30-day experiment. The incidence and severity of arthritis were evaluated using clinical parameters. At the end of experiments, tissue swelling and bone destruction of the hind paws were assessed by computed tomography (CT) and histopathological analyses. Serum levels of tumor necrosis factor (TNF-α), interleukin-1β (IL-1β), IL-6, and IL-17A and IL-17F were measured by ELISA, and protein expression of matrix metalloproteinases-1 (MMP-1), MMP-3 and tissue inhibitor of MMP-1 (TIMP-1) were detected by Western blot. RESULTS Treatment with KHS dose-dependently inhibited paw swelling and reduced arthritis scores of AIA rats. CT images displayed that KHS remarkably protected AIA rats from tissue swelling and bone erosion of joints. Histopathological analyses revealed that KHS markedly reduced inflammatory cell infiltration, synovial proliferation, and the formation of pannus in the ankle joints of AIA rats. KHS was found to significantly suppress the production of TNF-α, IL-1 β, IL-6, IL-17A and IL-17F, inhibited the protein expression of MMP-1 and MMP-3, and elevated the protein expressions of TIMP-1. CONCLUSION KHS demonstrates potential anti-arthritic effects via inhibiting pivotal mediators of inflammation and cartilage destruction. This study strongly supports identification and isolation of active fractions of KHS which would be a potential candidate for further investigation as a new anti-arthritic botanical drug.

Abstract
Twenty-four compounds were isolated from the roots of Polygonatum cyrtonema Hua, including a new octopamine dimer, named trans-bis(N-feruloyl)octopamine (1). The structure was established on the basis of spectroscopic and chemical methods. All the extracts and compounds were evaluated for cytotoxic and antioxidant activities by using MTT and chemiluminescence assay. The extracts showed activity against MCF-7 and HepG-2 cell lines from IC50 0.30 to 1.01 mg mL-1. Compound 3 exhibited activity against HepG-2 cell lines with IC50 8.99 μM. Compound 7 exhibited activity against Hela cell lines with IC50 2.53 μM and BGC-823 cell lines with IC50 7.77 μM. Moreover, compound 7 showed antioxidant with IC50 12 µM compared to the positive control with IC50 77 µM. Compound 16 exhibited activity against HepG-2 cell lines with IC50 1.05 μM and MCF-7 cell lines with IC50 1.89 μM. These results indicated that this plant might be potential in natural medicine and healthy food.

Abstract
Surgical site infections (SSIs) are the second most common health care associated infection reported to the National Health Safety Network of the centre of disease control and prevention. SSIs by Mycobacterium tuberculosis are uncommon and diagnosis can be missed. Our patient had primary tuberculosis at surgical site without any evidence of tuberculosis at initial investigation. She presented with repeated discharging sinus at the wound of elective lower uterine caesarean section (LUCS). The case was diagnosed by histo-pathological evidence of chronic granulomatous lesion suggestive of tuberculosis from the excised tissue from wound and detection of acid fast bacilli (AFB) from swab by Ziehl Neelsen staining. After proper diagnosis the patient was treated with anti-tubercular drugs regiment for six months as per schedule of national guidelines for management of tuberculosis of Bangladesh Government. Then the patient was cured from unusual long sufferings.

Abstract
Platelet aggregometry and dense granule adenosine triphosphate (ATP) release assays are helpful to diagnose platelet disorders. Some laboratories simultaneously measure aggregation and ATP release using Chronolume® a commercial reagent containing D-luciferin, firefly luciferase and magnesium. Chronolume® can potentiate sub-maximal aggregation responses, normalising canine platelet disorder findings. We investigated if Chronolume® potentiates human platelet aggregation responses after observing discrepancies suspicious of potentiation. Among patients simultaneously tested by light transmission aggregometry (LTA) on two instruments, 18/43 (42%), including 14/24 (58%) with platelet disorders, showed full secondary aggregation with one or more agonists only in tests with Chronolume®. As subjects with Quebec platelet disorder (QPD) did not show the expected absent secondary aggregation responses to epinephrine in tests with Chronolume®, the reason for the discrepancy was investigated using samples from 10 QPD subjects. Like sub-threshold ADP (0.75 μM), Chronolume® significantly increased QPD LTA responses to epinephrine (p<0.0001) and it increased both initial and secondary aggregation responses, leading to dense granule release. This potentiation was not restricted to QPD and it was mimicked adding 1-2 mM magnesium, but not D-luciferin or firefly luciferase, to LTA assays. Chronolume® potentiated the ADP aggregation responses of QPD subjects with a reduced response. Furthermore, it increased whole blood aggregation responses of healthy control samples to multiple agonists, tested at concentrations used for the diagnosis of platelet disorders (p values <0.05). Laboratories should be aware that measuring ATP release with Chronolume® can potentiate LTA and whole blood aggregation responses, which alters findings for some human platelet disorders, including QPD.

Abstract
BACKGROUND Multimerin 1 (MMRN1) is a large, homopolymeric adhesive protein, stored in platelets and endothelium, that when released, binds to activated platelets, endothelial cells and the extracellular matrix. OBJECTIVES The goals of our study were to determine if (i) MMRN1 supports adhesion of resting and/or activated platelets under conditions of blood flow, and (ii) if MMRN1 enhances platelet adhesion to types I and III collagen. PATIENTS/METHODS Platelet adhesion was evaluated using protein-coated microcapillaries, with or without added adhesive proteins and receptor antibodies. Platelets from healthy controls, Glanzmann thrombasthenia (GT) and severe von Willebrand factor (VWF)-deficient donors were tested. RESULTS MMRN1 supported the adhesion of activated, but not resting, washed platelets over a wide range of shear rates. At low shear (150 s(-1)), this adhesion was supported by integrins alphavbeta3 and glycoprotein (GP) Ibalpha but it did not require integrins alphaIIbbeta3 or VWF. At high shear (1500 s(-1)), adhesion to MMRN1 was supported by beta3 integrin-independent mechanisms, involving GPIbalpha and VWF, that did not require platelet activation when VWF was perfused over MMRN1 prior to platelets. MMRN1 bound to types I and III collagen, independent of VWF, however, its enhancing effects on platelet adhesion to collagen at high shear were VWF dependent. CONCLUSIONS MMRN1 supports platelet adhesion by VWF-dependent and -independent mechanisms that vary by flow rate. Additionally, MMRN1 binds to, and enhances, platelet adhesion to collagen. These findings suggest that MMRN1 could function as an adhesive ligand that promotes platelet adhesion at sites of vascular injury.

Abstract
Phosphoinositide 3-kinase (PI 3-kinase) exists in cells as a family of isoforms. The enzymes are important regulators of fundamental metabolic processes, such as energy utilization, growth, cell proliferation and survival. They are activated by cell surface receptors for hormones, and by G-protein coupled receptors. Enzyme p110 gamma, in particular, catalyzes production of second messengers from inositol phospholipids, including phosphoinositide (3,4,5) triphosphate or PtdIns (3,4,5) P3, PtdIns (3,4) P2 and Ptdins (3) P. The objective of this study was to corroborate the role of PI 3 kinase in ROS generation and in platelet aggregation through the use of four chemically unrelated inhibitors of PI 3 kinase: wortmannin, LY-294002, resveratrol and quercetin. In this study, we describe the effects of four PI 3-kinase inhibitors on the production of reactive oxygen species (ROS) and platelet aggregation induced by a diversity of agonists. Neutrophils and platelets were obtained from human blood and macrophages from mouse peritoneal cavity. ROS production was measured by a luminol-enhanced chemiluminescence assay; aggregation was measured in platelet-rich plasma (PRP) with a Chronolog Dual Channel Lumi-Aggregometer. Effects of graded concentrations of four enzyme inhibitors (wortmannin, LY-294002, resveratrol and quercetin) were evaluated. All inhibitors caused concentration-dependent depression of ROS generation and human platelet aggregation. They differed only in their potencies as revealed by concentration-response data. Moreover, inhibitors blocked activity of three chemically unrelated stimulants of aggregation: ADP, collagen and epinephrine. We conclude that inhibition of PI 3-kinase would appear to be a useful therapeutic goal in those conditions where the activities of platelets and/or phagocytes become aberrant.

Abstract
Heat shock proteins (hsp) may be involved in the initiation and perpetuation of autoimmune diseases. In order to investigate the possible role of hsp and other intracellular proteins of Mycobacterium tuberculosis in the autoantibody production in SLE, the immuno-crossreactivity of SLE autoantibodies with Mycobacterium tuberculosis sonic extract and hsp-70 kDa was investigated. These proteins showed significant binding with Protein A-Sepharose isolated SLE IgG. Western blotting of hsp-70 with SLE IgG showed strong recognition, suggesting possible involvement of hsp and other intracellular proteins of Mycobacterium tuberculosis in the autoantibody induction in SLE.

Abstract
Reactive oxygen species (ROS) are implicated in a variety of human diseases. The formation of pathogenic anti-DNA antibodies in systemic lupus erythematosus (SLE) has been extensively investigated. ROS-modified DNA has been found to be a better antigen for anti-DNA antibodies found in SLE sera. A comparative binding of SLE autoantibodies with native poly(I), ROS-poly(I) and nDNA has been studied. Affinity-purified SLE IgG exhibited a high degree of specificity towards the ROS-modified poly(I) in comparison to native DNA and native poly(I), reiterated visually by gel retardation assay. The data suggested that hydroxyl radical-modified nucleic acids like RNA and DNA might be agent for the induction of circulating SLE anti-DNA autoantibodies.

Abstract
The effect of hydroxyl radicals on polyinosinic acid [poly(I)] was studied. Strand breaks, base alteration and a decrease in absorbance at 248 nm (lambda max) were observed upon *OH modification of poly(I). The broad antigen specificity of the induced anti-poly(I) and anti-ROS-poly(I) antibodies showed diverse antigen binding characteristics similar to those of SLE autoantibodies. Recognition of both poly(I) and ROS-poly(I) by human SLE anti-DNA autoantibodies was observed. The possible significance of these findings in the etiology of SLE has been discussed.
