A suitable small animal model may help in the screening and evaluation of new drugs, especially those from natural products, which can be administered at lower dosages, fulfilling an urgent worldwide need. In this study, we explore whether zebrafish could be a model organism for carrageenan-induced abdominal edema. The research results showed that intraperitoneal (i.p.) administration of 1.5% -carrageenan in a volume of 20 L significantly increased abdominal edema in adult zebrafish. Levels of the proinflammatory proteins tumor necrosis factor- (TNF-) and inducible nitric oxide synthase (iNOS) were increased in carrageenan-injected adult zebrafish during the development of abdominal edema. An associated enhancement was also observed in the leukocyte marker, myeloperoxidase (MPO). To support these results, we further observed that i.p. methylprednisolone (MP; 1 g), a positive control, significantly inhibited carrageenan-induced inflammation 24 h after carrageenan administration. Furthermore, i.p. pretreatment with either an anti-TNF- antibody (15 dilution in a volume of 20 L) or the iNOS-selective inhibitor aminoguanidine (AG; 1 g) inhibited carrageenan-induced abdominal edema in adult zebrafish. This new animal model is uncomplicated, easy to develop, and involves a straightforward inducement of inflammatory edema for the evaluation of small volumes of drugs or test compounds.

Subject: Hyaluronic acid (HA) is widely used to relieve the symptoms of osteoarthritis (OA). An association of reduction of glutamate content with the synovial fluid of OA rats was reported previously. Design: Anterior cruciate ligament transaction (ACLT) was performed on one knee in male Wistar rats, the other knee was assigned to sham control and HA or saline was injected intraarticularly into the ACLT knee from week 3 to week 7. Knee dialysate was collected for amino acid measurement at week 20. Morphology and histopathology of the femoral medial condyles and synovium were examined and evaluated using Mankin and synovitis scores. Results: HA injection provided better cartilage (3.38 ± 0.03 vs. 5.45 ± 0.0.02) and synovial condition (3 ± 0.02 vs. 6.03 ± 0.02) than saline controls. Moreover, HA injection reduced the concentration of glutamates in knee dialysates compared to saline controls (1.11 ± 0.14-folds and 2.21 ± 0.19-folds of the sham-operated knee, respectively). Cystine/glutamate antiporter system expression was significantly downregulated in the saline group, but not in the HA group (0.32 ± 0.08-folds and 0.71 ± 0.10-folds of the sham-operated knee, respectively). Conclusion: Early intraarticular injection of HA attenuates the progression of cartilage destruction in the ACLT knee, and the downregulation of the cystine/glutamate antiporter system was accompanied by the progression of OA. © 2013 Informa Healthcare USA, Inc.

Objectives: to examine the effectiveness of a birth ball exercise programme during childbirth by measuring childbirth self-efficacy and childbirth pain. In addition, it tested the mediating effects of childbirth self-efficacy on the relationship between the birth ball exercise programme and childbirth pain.Design: randomised controlled trial.Participants and setting: the study was conducted from December 2008 to November 2009, at two birth units, one at a regional hospital and one at a medical centre, with 600 and 1022 annual births, respectively. One hundred and eighty-eight expectant mothers were recruited (recruitment rate: 47%) and were allocated by block randomisation into the two arms of the study, but only 48 intervention and 39 control group participants completing the trial.Interventions: the birth ball exercise programme consisted of a 26-page booklet and a 19-minute videotape, with periodic follow-ups during prenatal checks. All members of the experimental group were asked to practise the exercises and positions at home for at least 20 minutes three times a week for a period of 6-8 weeks. Each woman in the experimental group was given a birth ball for use during labour and encouraged every hour to choose the most comfortable positions, movements, and exercises. Both the experimental and control groups received standard nursing and midwifery care from hospital staff nurses in all aspects of pregnancy and childbirth.Measurement and findings: when cervical dilations were four centimetres and eight centimetres, the women completed demographic and obstetrics information, the Childbirth Self-efficacy Inventory (CBSEI), and the short form of the McGill Pain Questionnaire (SF-MPQ). Our study revealed that birth ball exercises provided statistically significant improvements in childbirth self-efficacy and pain. Specifically, self-efficacy had a 30-40% mediating effect on relationships between birth ball exercises and childbirth pain. Mothers in the experimental group had shorter first-stage labour duration, less epidural analgesia, and fewer caesarean deliveries than the control group.Conclusions and implications for practice: clinical implementation of the birth ball exercise programme could be an effective adjunctive tool to improve childbirth self-efficacy and reduce pain among women in labour. On the basis of our mediating model, the results further suggest that confidence is greater after prenatal preparation powerfully related to decreased pain perception and decreased medication/analgesia use during labour. © 2011 Elsevier Ltd.

Purpose: This study aims to evaluate and quantify the possible effect of psychological symptoms on healthy workers' quality of life (QOL). Methods: The workers were recruited from a factory in south Taiwan. We assessed their psychological symptoms with a 5-item brief symptom rating scale (BSRS-5) and measured the QOL using the Taiwanese version of the World Health Organization Quality of Life (WHOQOL)- BREF. Multiple linear regression analysis was conducted to explore the association between the two tools after control of confounding by other predictors. Results: A total of 1,080 workers, who attended a physical examination, completed questionnaires and informed consent forms. Scores on the BSRS-5 significantly predicted scores in each domain and items of the WHOQOL-BREF. The magnitude of psychological domain score seemed to be affected the most; every 1 point increase in BSRS-5 was associated with a 0.39 raw score (equivalent to 2.44 percentile) decrease in QOL. The sleep facet of WHOQOL appeared to have the highest association, followed by items of negative feelings, energy, and concentration. Conclusions: The BSRS-5 score is predictive for scores of all four domains and 26 items of the Taiwanese version of the WHOQOL-BREF for regular factory workers. © The Author(s) 2011.

Surgical Endoscopy and Other Interventional Techniques | Year: 2011
Background: Emergency surgical procedures frequently must be performed at times when availability of adequately trained personnel is problematic yet the requirements for maintaining surgical quality and patient safety remain unchanged. This report aims to describe a safe, effective, transumbilical, one-port laparoscopic technique for appendectomy that can be performed by one surgeon. Methods: Between January 2006 and December 2008, transumbilical one-port laparoscopic appendectomy (TOPLA) was used by two pediatric surgeons in the authors' department to treat 152 consecutive patients presenting with simple and complicated appendicitis. With the patient placed in the Trendelenburg position and rotated to the left, a single surgeon was easily able to perform the procedure using a 10-mm 0° operative laparoscope (Karl Storz) with a 5-mm working channel. The appendix was lifted with transabdominal suspensory sutures to facilitate its removal. The results were compared with those for 112 patients receiving open appendectomy (OA) during the same period. Results: The operative time was significantly shortened using TOPLA (mean, 61.5 min) compared with using OA (mean, 118.3 min) (p = 0.000). Despite significantly higher numbers of patients with complicated appendicitis enrolled in the TOPLA arm of the study, the rate of wound infection was significantly lower after TOPLA (0%, 0/152) than after OA (9.8%, 11/112) (p = 0.000). The number of patients requesting intramuscular or intravenous analgesics for pain relief was significantly lower after TOPLA than after OA. The overall results for TOPLA were comparable with those for the more common three-port laparoscopic procedure, but it offers the alternative of having an inconspicuous scar hidden within the umbilicus. Conclusion: This report describes a simple and safe laparoscopic procedure that offers an effective way for one surgeon to treat simple and complicated appendicitis through a single port with satisfactory cosmetic outcomes. © 2010 Springer Science+Business Media, LLC.

Osteoclasts are multinucleated giant cells of macrophage/monocyte lineage, and cell differentiation with the upregulation of osteoclast-related proteins is believed to play a major role in the destruction of the joints in the course of rheumatoid arthritis (RA). Pro-inflammatory cytokines, such as interleukin-17A (IL-17A) and macrophage colony-stimulating factor (M-CSF), can be overexpressed in RA and lead to osteoclastogenesis. In a previous study, we found that cultured-type soft coral-derived excavatolide B (Exc-B) exhibited anti-inflammatory properties. In the present study, we thus aimed to evaluate the anti-arthritic activity of Exc-B in in vitro and in vivo models. The results demonstrated that Exc-B inhibits LPS-induced multinucleated cell and actin ring formation, as well as TRAP, MMP-9, and cathepsin K expression. Additionally, Exc-B significantly attenuated the characteristics of RA in adjuvant (AIA) and type II collagen-induced arthritis (CIA) in rats. Moreover, Exc-B improved histopathological features, and reduced the number of TRAP-positive multinucleated cells in the in vivo AIA and CIA models. Immunohistochemical analysis showed that Exc-B attenuated the protein expression of cathepsin K, MMP-2, MMP-9, CD11b, and NFATc1 in ankle tissues of AIA and CIA rats. Level of interleukin-17A and macrophage colony-stimulating factor were also decreased by Exc-B. These findings strongly suggest that Exc-B could be of potential use as a therapeutic agent by inhibiting osteoclast differentiation in arthritis. Moreover, this study also illustrates the use of the anti-inflammatory marine compound, Exc-B, as a potential therapeutic strategy for RA.

Growth arrest-specific protein 6 (Gas6) works synergistically with erythropoietin (EPO) to increase the proliferation and maturation of erythroblasts. However, the role of Gas 6 levels on EPO resistance in hemodialysis (HD) patients remains unclear. Therefore, the objective of this study was the first to examine the correlation between plasma Gas6 levels and EPO resistance in HD patients. We enrolled 134 HD patients and 85 healthy individuals. The HD patients were divided into 2 groups: 98 non-EPO-resistant patients and 36 EPO-resistant patients. Plasma levels of Gas6, interleukin 6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), and albumin were quantified. Compared with non-EPO-resistant patients, EPO-resistant patients had elevated plasma concentrations of Gas6 (15.43.3 vs. 13.73.2ng/mL, P=0.006), IL-6 (3.13.1 vs. 2.11.5pg/mL, P=0.009), and hs-CRP (12.725.2 vs. 4.55.5mg/L, P=0.002). In EPO-resistant HD patients, plasma Gas6 levels were negatively correlated with albumin levels (r=-0.388, P<0.021). Elevated Gas6 levels are associated with EPO resistance in HD patients. Also, EPO resistance is related to inflammation and malnutrition. Thus, circulating Gas6 levels could be used as the potential marker in HD patients with EPO resistance.

In recent years, several marine-derived compounds have been clinically evaluated. Diterpenes are secondary metabolites from soft coral that exhibit anti-inflammatory, anti-tumor and cytotoxic activities. In the present study, we isolated a natural diterpene product, excavatolide B, from cultured Formosan gorgonian Briareum excavatum and investigated its anti-inflammatory activities. We found that excavatolide B significantly inhibited the mRNA expression of the proinflammatory mediators, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), in lipopolysaccharide (LPS)-challenged murine macrophages (RAW 264.7). We also examined the anti-inflammatory and anti-nociceptive effects of excavatolide B on intraplantar carrageenan-induced inflammatory responses. Excavatolide B was found to significantly attenuate carrageenan-induced nociceptive behaviors, mechanical allodynia, thermal hyperalgesia, weight bearing deficits and paw edema. In addition, excavatolide B inhibited iNOS, as well as the infiltration of immune cells in carrageenan-induced inflammatory paw tissue.

Deoxycholic acid (DOA) is one of the secondary bile acids used as a mild detergent for the isolation of membrane associated proteins. This study examined whether the secondary bile acid, DOA, altered Ca(2+) movement, cell viability and apoptosis in SCM1 human gastric cancer cells. The Ca(2+)-sensitive fluorescent dye fura-2 was used to measure [Ca(2+)]i. DOA-evoked [Ca(2+)]i rises concentration dependently. The response was reduced by removing extracellular Ca(2+). DOA-evoked Ca(2+) entry was inhibited by store-operated Ca(2+) channel inhibitors (nifedipine, econazole and SKF96365), the protein kinase C (PKC) activator phorbol 12-myristate 13 acetate (PMA) and the PKC inhibitor GF109203X. In Ca(2+)-free medium, treatment with the endoplasmic reticulum Ca(2+) pump inhibitor thapsigargin (TG) abolished DOA-evoked [Ca(2+)]i rises. Conversely, treatment with DOA abolished TG-evoked [Ca(2+)]i rises. Inhibition of phospholipase C with U73122 abolished DOA-evoked [Ca(2+)]i rises. At 100-500M, DOA decreased cell viability, which was not changed by chelating cytosolic Ca(2+) with 1,2-bis(2-aminophenoxy)ethane-N,N,N,N-tetraacetic acid-acetoxymethyl ester (BAPTA/AM). DOA between 100 and 300M also induced apoptosis. Collectively, in SCM1 cells, DOA-induced [Ca(2+)]i rises by evoking phospholipase C-dependent Ca(2+) release from the endoplasmic reticulum and Ca(2+) entry via store-operated Ca(2+) channels. DOA also caused Ca(2+)-independent apoptosis.
