Sorafenib is widely used for unresectable and metastatic hepatocellular carcinomas. Radiation recall dermatitis (RRD) is an acute inflammatory reaction confined to previously irradiated skin that occurs after the administration of certain drugs. RRD after sorafenib treatment is rare; five cases have been reported thus far. We describe a 44-year-old man irradiated for chest wall bone metastasis from hepatocellular carcinoma. Eight days after radiotherapy completion, systemic therapy for metastatic hepatocellular carcinoma was initiated with sorafenib treatment. Eleven days after starting sorafenib, the patient complained of erythematous rash with pruritus in the chest wall, in a location consistent with the previous radiation field. Sorafenib was continued at the same dose, despite the RRD. The skin reaction subsided over the next 2 weeks without any medical intervention.

Forsythiae fructus has traditionally been used for the treatment of erysipelas, skin rash and acute or chronic inflammatory disorders. The effect of Forsythiae fructus against lipopolysaccharide-induced inflammation was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, reverse transcription-polymerase chain reaction (RT-PCR), on mouse RAW 264.7 macrophages. Forsythiae fructus extract suppressed the expression of iNOS, COX-2 and NF-$_K$B mRNAs on the lipopolysaccharide-stimulated enhancement in RAW 264.7 macrophages. We examined the expression of iNOS and COX-2 in both mRNA and protein levels to investigate the mechanism by which Forsythiae fructus extract inhibits NO production. Forsythiae fructus extract significantly reduced iNOS, NF-$_K$B and PGE$_2$, but didn't inhibit COX-2 expression which was induced by LPS treatment in Raw 264.7 cells. These results suggest that Forsythiae fructus exerts anti-inflammatory effects probably by suppression of the iNOS and NF-$_K$B expressions.

Inula helenium L. is rich source of eudesmane-type sesquiterpene lactones, mainly alantolactone and isoalantolactone, which have the various pharmacological functions. In this study, we examined the inhibitory effects of nitric oxide (NO) production of hexane, methylene chloride, ethyl acetate, butanol, and water fractions from I. helenium and investigated the anti-inflammatory effect of hexane fraction of I. helenium (HFIH) in LPS-induced RAW 264.7 cells. Quantification of alantolactone and isoalantolactone from HFIH was carried out for the standardization by multiple reaction monitoring using triple quadrupole mass spectrometer. HFIH significantly inhibited inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) protein as well as their downstream products NO and prostaglandin $E_2$ ($PGE_2$) in LPS-stimulated RAW 264.7 cells. Moreover, HFIH suppressed $NF-{\kappa}B$ transcriptional activity by decreasing the translocation of p65 to the nucleus. The in vivo study further confirmed that HFIH attenuated the paw edema induced by carrageenan in an acute inflammation model. These findings suggest that HFIH may be useful as a promising phytomedicine for inflammatory-associated diseases.

Objective : In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods : Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender joint counts, swollen joint counts, Visual analog scale(VAS), morning in stiffness, ESR, C-reactive protein(CRP) were analyzed before and after BV therapy. Results : The results as follows: 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy($9.0{\pm}7.9$ vs $15{\pm}11.4$, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy ($5.0{\pm}6.1$ vs $1.5{\pm}2.3$, p=0.001). 3. VAS in patients after BV therapy was significantly lower than before BV therapy($60.8{\pm}17.6$ vs $38.0{\pm}15.9$, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy($119.1{\pm}112.6min$ vs $59.0{\pm}89.7min$, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions: BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed in log-term effect of BV therapy.

Traditionally, the thorns of Gleditsia sinensis LAM. (GS) have been used for the treatment of various types of cancer and heart, skin, vascular and inflammatory diseases. However, there have been no reports on the antinociceptive or antiinflammatory properties of the thorn of GS. The present study was carried out to evaluate the anti-inflammatory and antinociceptive effects of the ethanolic extract of GS (EEGS) and its sub-fractions. The administration of EEGS (500 mg/kg) or its butanolic fraction (50 and 100 mg/kg) reduced the frequency of the acetic acid-induced writhing reflex in mice. In addition, the administration of the butanolic fraction of EEGS (50 and 100 mg/kg) prolonged the latency of reaction at the hot plate in mice. The butanolic fraction of EEGS also inhibited lipopolysaccharide-induced nitric oxide, prostaglandin $E_2$, and tumor necrosis factor-$\acute{a}$ production in the RAW 264.7 cell line. These results suggest that EEGS has anti-inflammatory and analgesic properties and is a potential therapeutic for inflammation and nociception.

Objective : Radiation therapy is an important treatment for brain tumor. However, serious complications such as radiation necrosis can occur and it may be secondary to the expression of acute phase genes, like cytokines. In particular, inflammatory cytokines (IL-$1{\beta}$, TNF-${\alpha}$) and other immunomodulatory cytokines (TNF-${\alpha}$, TGF-${\beta}1$) might be changed after irradiation (high single dose irradiation). Although it has been reported that IL-1 level is remarkably elevated within 8 week after the irradiation to the rat brain. the change of cytokines levels at acute phase (within 24 hours) has not been reported. In the present study, we examined TNF-${\alpha}$, TGF-${\beta}1$, and IL-$1{\beta}$ levels in acute phase to clarify the early effect of cytokines on the radiation-induced brain damage. Methods : Fifty Sprague-Dawley rats were used and these were divided into irradiation group and control group. After a burr-hole trephination on the right parietal area using a drill, a single 10Gy was irradiated at the trephined site. Their forebrains were extirpated at 30 min, 2 hr, 8 hr, 12 hr and 24 hr, respectively and examined for the expression of TNF-${\alpha}$, TGF-${\beta}1$, and IL-$1{\beta}$. Results : The expression of TNF-${\alpha}$ and TGF-${\beta}1$ were decreased until 12 hr after irradiation but elevated thereafter. The expression of IL-1 was peak at 8 hr and then decreased until 12 hr but elevated after this time window. The present study indicated that expression of cytokines (TNF-${\alpha}$, TGF-${\beta}1$ and IL-$1{\beta}$) were increased at 24 hr after the irradiation to the rat brain. IL-$1{\beta}$ level, on the other hand. reached peak at 8 hr after radiation injury. Conclusion : These findings indicate that IL-1, among various cytokines, may have a more important role in the inflammatory reaction by radiation injury at acute phase and provide some clues for better understanding of the pathogenesis of radiation injury.

IL-22, a pleiotropic cytokine, is known to have a profound effect on the regeneration of damaged intestinal barriers. The tissue-protective properties of IL-22 are expected to be potentially exploited in the attenuation and treatment of colitis. However, because of the disease-promoting role of IL-22 in chronic inflammation, a comprehensive evaluation is required to translate IL-22 into the clinical domain. Here, we present the effective production of soluble human IL-22 in bacteria to prove whether recombinant IL-22 has the ability to ameliorate colitis and inflammation. IL-22 was expressed in the form of a biologically active monomer and non-functional oligomers. Monomeric IL-22 (mIL-22) was highly purified through a series of 3 separate chromatographic methods and an enzymatic reaction. We reveal that the resulting mIL-22 is correctly folded and is able to phosphorylate STAT3 in HT-29 cells. Subsequently, we demonstrate that mIL-22 enables the attenuation of dextran sodium sulfate-induced acute colitis in mice, as well as the suppression of pro-inflammatory cytokine production. Collectively, our results suggest that the recombinant mIL-22 is suitable to study the biological roles of endogenous IL-22 in immune responses and can be developed as a biological agent associated with inflammatory disorders.

Substantial evidence has accumulated that Alzheimer's disease is associated with a local inflammatory reaction in senile plaques which may be immunemediated, and includes extensive Brain Neuroglial invasion, lymphocytic infiltration, cytokine deposition. Tumor necrosis factor a (TNF-a) is a cytokine which plays an important immunoenhancing role in the local acute and chronic inflammatory response in response to a variety of stimuli. The neuropeptide, substance P, can stimulate secretion of TNF-a from Brain Neuroglial cells. Neuroglia have substance P receptors in the central nervous system. WQ investigated whether RADIX ASPARAGI inhibits secretion of TNF-a from primary cultures of Brain Neuroglial cells containing both astrocyte (∼90%) and microglia (∼10%). RADIX ASPARAGI dose-dependently inhibited the TNF-a secretion induced by substance P plus lipopolysaccharide (LPS). In cultures enriched for micoglia (>95% pure). LPS stimulated the secretion of TNF-a but substance P caused no enhancement. Because there was no synergism between substance P and LPS in the microglial cultures it is resonable to substance P madiated enhancement of TNF-a secretion. IL-1 is a modulator of TNF-a secretion in the immune system. Also IL-1 has been shown to elevate TNF- a secretion from LPS-stimulated Brain Neuroglial cells while having no effect on Brain Neuroglial cells in the absence of LPS. We therfore investigated whether IL-1 mediates the RADIX ASPARAGI inhibition of TNF-a secretion form primary Brain Neuroglial cells. Treatment of RADIX ASPARAGI to mixed cultures stimulated with both substance P and LPS decreased TNF-a secretion to the level observed with LPS alone. These results indicate that RADIX ASPARAGI possess strong antiinflammatory activity in the cental nervous system by inhibition of inflammatory cytokines secretion from Brain Neuroglial cells.

The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been spreading worldwide since December 2019. Hundreds of cases of children and adolescents with Kawasaki disease (KD)-like hyperinflammatory illness have been reported in Europe and the United States during the peak of the COVID-19 pandemic with or without shock and cardiac dysfunction. These patients tested positive for the polymerase chain reaction or antibody test for SARS-CoV-2 or had a history of recent exposure to COVID-19. Clinicians managing such patients coined new terms for this new illness, such as COVID-19-associated hyperinflammatory response syndrome, pediatric inflammatory multisystem syndrome temporally associated with COVID-19, or COVID-19-associated multisystem inflammatory syndrome in children (MIS-C). The pathogenesis of MIS-C is unclear; however, it appears similar to that of cytokine storm syndrome. MIS-C shows clinical features similar to KD, but differences between them exist with respect to age, sex, and racial distributions and proportions of patients with shock or cardiac dysfunction. Recommended treatments for MIS-C include intravenous immunoglobulin, corticosteroids, and inotropic or vasopressor support. For refractory patients, monoclonal antibody to interleukin-6 receptor (tocilizumab), interleukin-1 receptor antagonist (anakinra), or monoclonal antibody to tumor necrosis factor (infliximab) may be recommended. Patients with coronary aneurysms require aspirin or anticoagulant therapy. The prognosis of MIS-C seemed favorable without sequelae in most patients despite a reported mortality rate of approximately 1.5%.
