Abstract
Myofibroblasts (MFs), a contractile subset of fibroblasts, play a pivotal role in physiological wound healing and in the development of many fibroconnective disorders. The complex cytokine network regulating the function of MFs in joint stiffness is still poorly understood. In this in vitro study, we investigated the effect of the cytokine Interferon-gamma (IFN-γ) on MFs isolated from human joint capsules. MFs were cultivated either in the presence of increasing concentrations of IFN-γ alone or in combination with IFN-γ neutralizing antibodies. Cell viability, cytotoxicity, apoptosis, and mRNA gene expression of the MF markers alpha-smooth muscle actin (α-SMA) and collagen type I were analyzed in MF cultures. Contraction potential was analyzed in an established collagen gel contraction assay simulating the extracellular matrix. Using immunofluorescence staining, we could verify that MFs express IFN-γ-receptor (R)-1 on their membrane. IFN-γ decreased MF viability and significantly elevated the apoptosis rate in a dose-dependent manner. IFN-γ down-regulated α-SMA and collagen type I mRNA expression which was associated with a diminished MF mediated contraction of the gel matrices. These effects were suppressed by simultaneous treatment of cells with a neutralizing IFN-γ antibody. Our experiments confirm the hypothesis that the cytokine IFN-γ is a crucial component of the regulatory network of capsule MFs. IFN-γ notably influences the ability of MFs to contract collagen matrices by suppressing α-SMA gene expression. IFN-γ is toxic for MFs in high concentrations and may negatively regulate the number of pro-fibrotic MFs during the healing process via induction of cell apoptosis. © 2017 Orthopaedic Research Society.

Influence of the anti-inflammatory cytokine interleukin-4 on human joint capsule myofibroblasts. J Orthop Res 2017; 35:1290-1298.

Abstract
Post-traumatic joint contracture was reported to be associated with elevated numbers of contractile myofibroblasts (MFs) in the healing capsule. During the physiological healing process, the number of MFs declines; however, in fibroconnective disorders, MFs persist. The manifold interaction of the cytokines regulating the appearance and persistence of MFs in the pathogenesis of joint contracture remains to be elucidated. The objective of our current study was to analyze the impact of the anti-inflammatory cytokine interleukin (IL)-4 on functional behavior of MFs. Cells were isolated from human joint capsule specimens and challenged with three different concentrations of IL-4 with or without its neutralizing antibody. MF viability, contractile properties, and the gene expression of both alpha-smooth muscle actin (α-SMA) and collagen type I were examined. Immunofluorescence staining revealed the presence of IL-4 receptor (R)-alpha (α) on the membrane of cultured MFs. The cytokine IL-4 promoted MF viability and enhanced MF modulated contraction of collagen gels. Moreover, IL-4 intervened in gene expression by up-regulation of α-SMA and collagen type I mRNA. These effects could be specifically lowered by the neutralizing IL-4 antibody. On the basis of our findings we conclude that the anti-inflammatory cytokine IL-4 specifically regulates viability and the contractile properties of MFs via up-regulating the gene expression of α-SMA and collagen type I. IL-4 may be a helpful target in developing anti-fibrotic therapeutics for post-traumatic joint contracture in human. © 2016 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Multi-dose parecoxib provides an immunoprotective effect by balancing T helper 1 (Th1), Th2, Th17 and regulatory T cytokines following laparoscopy in patients with cervical cancer. Mol Med Rep 2014; 11:2999-3008.

Abstract
Analgesic treatment with anti‑inflammatory drugs may aid the prevention of postoperative pain and the attenuation of the postoperative immune inflammatory response. The current study presents a randomized, double‑blind controlled study, which was performed to investigate the levels of Th1, Th2, Th17 and Treg cytokines, including interleukin (IL)‑2, interferon (IFN)‑γ, IL‑4, IL‑10, IL‑17, IL‑23 and transforming growth factor (TGF)‑β in the peripheral blood of patients with cervical cancer following laparoscopy. The effects of perioperative multi‑dose parecoxib on postoperative immune function was evaluated. A total of 80 patients with cervical cancer (stage IB/IIA, ASA I‑III, aged 18‑65 years) that were scheduled for laparoscopy were randomly assigned into either the parecoxib (I; n=40) or control (II; n=40) groups. Group I received 40 mg parecoxib 30 min prior to surgery and then every 12 h subsequent to surgery for 60 h, and group II received normal saline at the corresponding time points. Intravenous tramadol (100 mg) was prescribed for pain relief as required. The mRNA and protein expression levels of cytokines in the peripheral blood were detected by quantitative polymerase chain reaction and ELISA. Pain visual analog scales (VAS) and incidence, analgesic relief, adverse events and the length of hospital stay were recorded. It was demonstrated that the mRNA and protein levels of IL‑2, IFN‑γ and IL‑17 in the two groups were reduced subsequent to surgery, while mRNA and protein expression levels of IL‑4, IL‑10 and TGF‑β were enhanced. Administration of multi‑dose parecoxib may diminish the increase in postoperative IL‑2, IFN‑γ and IL‑17 levels, and suppress the excessive production of IL‑4, IL‑10 and TGF‑β. This effect is accompanied by lower VAS scores, pain incidence, postoperative nausea/vomiting and infections. In conclusion, perioperative multi‑dose parecoxib was able to alleviate postoperative pain and ameliorate surgery‑induced immune suppression by balancing Th1, Th2, Th17 and Treg cytokines following laparoscopy in patients with cervical cancer. The current study provides support to the hypothesis that parecoxib may be a more effective therapeutic strategy than the currently available options, for postoperative pain and immune function management of patients with cancer.

Abstract
OBJECTIVE To delineate the role of T-helper 2 (Th2) cytokines in the induction of trauma induced myeloid suppressor cells (TIMSC) and the regulation of nitric oxide production. BACKGROUND Trauma induces myeloid cells that express CD11b+/Gr1+ and arginase 1 and exhibit an immune suppressing activity. This article explores the mechanisms that induce TIMSC and the effects on nitric oxide production in response to endotoxin. METHODS TIMSC were studied in response to Th2 cytokines and a subsequent challenge to endotoxin. The role of Th2 cytokines was studied in STAT6-/- mice. Accumulation of TIMSC in spleens was studied using flow cytometry and immunhistochemistry. Plasma was recovered to measure accumulation of nitric oxide metabolites. RESULTS TIMSC accumulated in the spleen of injured mice and were particularly sensitive to IL-4 and IL-13 with large inductions of arginase activity. Significant blunting in both the accumulation of TIMSC in the spleen and induction of arginase 1 was observed in STAT6-/- mice after physical injury. Accumulation of nitric oxide metabolites to endotoxin was observed in STAT6-/- mice. CONCLUSION This study shows that induction of CD11b+/Gr1+ cells after physical injury play an essential role in the regulation of nitric oxide production after a septic challenge. The accumulation and induction of arginase 1 in TIMSC is Th2 cytokine dependent. To our knowledge, the role of TIMSC in the regulation of nitric oxide is a novel finding. This observation adds to the possibility that TIMSC could play an important role in immunosuppression observed after physical injury.

Abstract
BACKGROUND Surgical trauma contributes to postoperative immune suppression, which is associated with an increased susceptibility to subsequent infections. Electroacupuncture (EA) can alleviate pain and exert immunoregulatory effects. However, the mechanism underlying the immnuomodulation effects of EA is not fully elucidated. Therefore, we investigated the effects of EA on T helper (Th)1/Th2 cytokine production and mRNA expression and evaluated the signaling regulatory mechanism of EA effects. METHODS Rats were divided into four groups (n = 24 each): control, trauma, trauma (T) + sham EA, and T + EA. EA was applied to Zusanli (ST36) and Lanwei (Extra37) acupoints at 20 min after surgery for 30 min, and then performed once a day on postoperative days 1-5. Splenic T cells were isolated and the production and mRNA expression of interleukin (IL)-2, interferon-gamma, IL-4, and IL-10 were assayed. The activation of mitogen-activated protein kinase and the DNA binding activity of nuclear factor (NF)-kappaB and activator protein (AP)-1 were examined. RESULTS Paw withdrawal threshold and paw withdrawal latency were significantly increased in the T + EA group compared with the trauma group from postoperative day 1 (paw withdrawal threshold: 5.8 +/- 0.7 vs 3.0 +/- 0.7 g; paw withdrawal latency: 7.0 +/- 0.8 vs 4.5 +/- 0.5 s; P < 0.001) to day 5 (9.0 +/- 0.6 vs 5.5 +/- 0.6 g; 12.0 +/- 1.3 vs 7.0 +/- 0.8 s; P < 0.001). Th1 cytokine (IL-2 and interferon-gamma) production and mRNA expression in splenic T cells of traumatized rats were significantly decreased on postoperative day 3 (P < 0.001, trauma group versus control group), whereas Th2 cytokine (IL-4 and IL-10) production and mRNA expression were increased (P < 0.001). This was accompanied with a significant depression in the activity of extracellular-regulated protein kinase (ERK)1/2, p38, NF-kappaB, and AP-1 (P < 0.001, trauma group versus control group). EA administration increased Th1 cytokine protein and mRNA expression, suppressed Th2 cytokine protein and mRNA expression (P < 0.05, T + EA group versus trauma group), and increased the activity of ERK1/2, p38, NF-kappaB, and AP-1 (P < 0.001, T + EA group versus trauma group). CONCLUSIONS EA regulates a balance between Th1 and Th2 cytokines at protein and mRNA levels in splenic T cells, and, at least in part, involves the signaling pathways of ERK1/2, p38, NF-kappaB, and AP-1. The findings suggest that EA may improve immune suppression after surgical trauma.

Abstract
The quality and progress of treatment of 4849 multiple trauma patients treated at one institution was reviewed retrospectively. Three periods, 1975-1984 (decade I; n=1469) and 1985-1994 (decade II; n=1937) and 1995-2004 (decade III; n=1443) were compared. 65% of multiple trauma patients had cerebral injuries, 58% thoracic trauma and 81% extremity fractures (37% open injuries). Injury combinations decreased during all decades with head/extremity injuries being the most common combination. Throughout the three decades pre-hospital care became more aggressive with an increase of intravenous fluid resuscitation (I: 80%, II: 97%, III: 98%). Chest tube insertion decreased after an initial increase (I: 41%, II: 83%, III: 27%) as well as intubation (I: 82%, II: 94%, III: 59%). Rescue times were progressively shortened. For initial clinical diagnosis of massive abdominal haemorrhage ultrasound (I: 17%, II: 92%, III: 97%) replaced peritoneal lavage (I: 44%, II: 28%, III: 0%). CT-scans were used more frequently for the initial diagnosis of head injuries and other injuries to the trunk throughout the observation time. With regard to complications, acute renal failure decreased by half (I: 8.4%; II: 3.7%; III: 3.9%), ARDS initially decreased but increased again in the last decade (I: 18.1%, II: 13.4%, III: 15.3%), whereas the rate of multiple organ dysfunction syndrome (MODS) increased continuously (I: 14.2%, II: 18.9%, III: 19.8%) probably due to a decline of the mortality rate from 37% in the first to 22% in the second and 18% in the third decade and parallel increase of the time of death. These treatment results summarise the enormous clinical effort as well as medical progress in polytrauma management over the past 30 years. Further reduction of mortality is desirable, but probably only possible when immediate causal therapy of later posttraumatic organ failure can be established.
