In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: To introduce an elastomeric continuous infusion pump for pain control after outpatient orbital implant surgery.', 'Retrospective, noncomparative consecutive case series of all patients undergoing enucleation, evisceration, or secondary orbital implantation using the On-Q pain system between August 2004 and January 2006. Postoperative pain score, need for narcotics, and adverse events were recorded. The On-Q catheter is inserted intraoperatively through the lateral lower eyelid into the muscle cone under direct visualization, prior to the orbital implant placement. The On-Q system continually infuses anesthesia (bupivacaine) to the retrobulbar site for 5 days.', 'Among 20 patients, mean postoperative period pain score, with On-Q in place, was 1.3 (scale of 0 to 10). Nine patients (45%) did not need any adjunctive oral narcotics. Two patients experienced postoperative nausea. One catheter connector leaked, thereby decreasing delivery of retrobulbar anesthetic resulting a pain level of 6, the highest level in the study. There were no postoperative infections. No systemic toxic effects from bupivacaine were observed clinically.\Question: Do on-Q pump for pain control after orbital implant surgery?
The On-Q pain pump is widely available, low cost, and requires minimal patient manipulation for the use in orbital implant surgery. The device was safe and appeared to minimize postoperative pain in the authors' case series.

Context: The human RECQ DNA helicase family is involved in genomic stability. Gene mutations of RECQL2, RECQL3, and RECQL4 are associated with genetic disorders and induce early aging and carcinogenesis. Although previous studies have reported that the level of RECQL1 expression is correlated with the prognosis of some of malignancies, the function of RECQL1 is not yet clarified. The present study aimed to examine the relationship between prognosis and the level of RECQL1 expression in epithelial ovarian cancer (EOC), and to identify the role of RECQL1 in EOC cells.', 'The level of RECQL1 expression was determined immunohistochemically in 111 patients with EOC who received initial treatment at Hirosaki University hospital between 2006 and 2011. Effects of RECQL1 on cell growth or apoptosis were examined in vitro using wild-type and OVCAR-3 cells (RECQL1(+) cells) and similar cells transfected with RECQL1 siRNA transfected (RECQL1(-) cells).', 'The level of RECQL1 expression was not related to histological type, clinical stage, or retroperitoneal lymph node metastasis, but the expression level was significantly higher (P\u2009=\u20090.002) in patients with recurrence than those without recurrence, and progression-free survival and complete response rate to chemotherapy were also improved in patients with RECQL1-low expression (n = 39) stage III/IV EOC (P = 0.02 and P <0.05 vs RECQL1-high expression patients (n = ), respectively). A cell proliferation and colony formation assays revealed significantly less growth of RECQL1(-) cells compared to RECQL1(+) cells. A flow cytometry using annexin V -FITC and propidium iodide (PI) staining revealed a significant increase in apoptotic RECQL1(-) cells. Cell cycle analysis showed a significantly greater distribution in subG1 phase indicating apoptotic cells in RECQL1(-) cells than in RECQL1(+) cells.\Question: Is the level of RECQL1 expression a prognostic factor for epithelial ovarian cancer?
These results suggest that RECQL1 is a prognostic factor for EOC and that RECQL1 contributes to potential malignancy by inhibiting apoptosis.

Context: Trauma is believed to activate immunocytes but paradoxically also increases the risk of intraperitoneal infection.', 'To investigate these events by evaluating changes in the cytokine control networks of human peritoneal macrophages (PM phi) early after trauma.', 'Case-control study comparing cytokine messenger RNA (mRNA) expression by PM phi from patients with extra-abdominal trauma with that of both peripheral blood mononuclear cells (PBM) and PM phi obtained from healthy individuals.', 'Level I trauma center and basic science laboratory in a university hospital center.', 'Six patients with polytrauma (Injury Severity Score, > or = 15) with clinically negative diagnostic peritoneal lavages performed on routine indications at admission to the emergency department and six healthy age- and sex-matched individuals undergoing inguinal herniorrhaphy under local anesthesia.', 'Peritoneal macrophages were isolated from diagnostic peritoneal lavages in trauma patients. Identical lavages were performed through the hernia sac in the control group.', 'Cellular RNA was assayed for tumor necrosis factor alpha (TNF-alpha), interleukin-1 beta, IL-6, and IL-10 message by semiquantitative reverse-transcription polymerase chain reaction.', 'Normal PM phi expressed high levels of TNF-alpha mRNA relative to PBM, but expression of the other proinflammatory cytokines was equivalent to that of PBM. Peritoneal macrophage expression of TNF-alpha mRNA was markedly (64-fold) decreased after trauma (P < .001), when PBM expression of IL-10 mRNA was increased (P = .03).\Question: Is tumor necrosis factor alpha gene expression in human peritoneal macrophages suppressed by extra-abdominal trauma?

Human PM phi constitutively show high levels of TNF-alpha message expression, and this is down-regulated by polytrauma. This might constitute a functionally "primed" state. If so, TNF-alpha down-regulation might contribute to functional PM phi suppression after systemic injury.
