Abstract
Objective: To explore the effect of 18β-sodium glycyrrhetinic acid on thymic stromal lymphopoietin (TSLP) in nasal mucosa of allergic rhinitis (AR) rats. Methods: One hundred Wistar rats,half male and half female,were randomly divided into 5 groups by random number table method: control group, AR model group,budesonide group,18β-sodium glycyrrhetinic acid at dose of 20 mg/kg and 40 mg/kg groups, with 20 rats in each group. AR animal models were established by ovalbumin (OVA) sensitization in the other four experimental groups. After successful modeling, budesonide and 18β-sodium glycyrrhetinic acid were given in each group,and the detection time points were 2 weeks and 4 weeks. The distribution of TSLP in rat nasal mucosa was detected by immunohistochemistry,and the expression of TSLP in rat nasal mucosa was determined by Western blot at the protein level. The expression of TSLP-mRNA in rat nasal mucosa was detected and compared by real-time fluorescence quantitative PCR (RT-PCR) at mRNA level. The concentrations of IL-4 and OVA-sIgE in rat serum were measured and compared by ELISA. One-way analysis of variance and the least significant difference method were used for the comparison among groups, LSD t test was used for the comparison between the two groups,and the difference was statistically significant (P<0.05). Results: Immunohistochemistry confirmed existence of TSLP in rat nasal mucosa, especially in epithelial cells,endothelial cells and epithelial cilia. Western blot and RT-PCR suggested that the expression of TSLP and TSLP-mRNA in nasal mucosa of AR model group was significantly higher than that of control group (2 weeks TSLP: 1.795 9±0.131 4 vs 0.990 5±0.164 2, 4 weeks TSLP: 1.809 7±0.253 4 vs 0.870 3±0.124 4; 2 weeks TSLP-mRNA:4.582 9±0.697 7 vs 1.108 7±0.081 1, 4 weeks TSLP-mRNA:4.814 4±0.662 8 vs 1.001 0±0.155 3; all P<0.05). After 2 weeks and 4 weeks of drug intervention,the expression of TSLP and TSLP-mRNA was inhibited in nasal mucosa of budesonide group,18β-sodium sodium glycyrrhetinic acid at dose of 20 mg/kg and 40 mg/kg group,which was significantly different from that of AR model group (2 weeks TSLP: (0.897 8±0.081 8)/(1.072 1±0.113 6)/(1.396 6±0.133 9) vs 1.795 9±0.131 4; 4 weeks TSLP: (1.191 0±0.161 3)/(1.141 0±0.152 3)/(1.200 5±0.189 6) vs 1.809 7±0.253 4; 2 weeks TSLP-mRNA: (1.175 6±0.100 9)/(1.254 4±0.078 2)/(2.037 2±0.559 2) vs 4.582 9±0.697 7; 4 weeks TSLP-mRNA: (1.158 3±0.104 3)/(1.224 0±0.034 0)/(1.275 2±0.099 6) vs 4.814 4±0.662 8; all P<0.05), and not significantly different from control group. With the inhibition of TSLP, the concentrations of IL-4 and OVA-sIgE in rat serum were also decreased. Conclusion: 18β-sodium glycyrrhetinic acid has obvious inhibitory effect on TSLP in nasal mucosa of AR rats, which can control Th2 type immune inflammatory reaction.

Abstract
Objective: To investigate the efficacy and safety of pegaspargase, gemcitabine, and oxaliplatin(P-Gemox) chemotherapy combined with radiotherapy in the treatment of newly diagnosed, stage IE to IIE of Extranodal nasal type natural killer/T-cell lymphoma(ENKTL) patients.Method: P-Gemox chemotherapy combined with radiotherapy was used to analyze its clinical value and the factors affecting the prognosis in the treatment of 43 newly diagnosed ENKTL patients. In addition, toxicity related to chemotherapy was assessed. Result: The complete remission rate was 86.05% in 43 patients,the partial remission rate was 6.98%, and the total effective rate was 93.02%.Chi-square analysis showed tumor diameter, clinical stage and ECOG points were significant independent factors impacting on complete remission rate(P =0.025, 0.042, 0.037).The 1-year and 3-year overall survival rate and progression-free survival rate of 43 patients were 95.35% and 83.7%, 93.02% and 79.07%, respectively. Coxproportional analysis showed that tumor diameter and Ann Arbor stage were signifcant factors affecting overall survival(P =0.016,0.025).Adverse reactions caused by the P-Gemox chemotherapy regimen are mild and more common in grades I to II. Conclusion: The P-Gemox regimen combined with radiotherapy may be a promising option in the treatment of newly-diagnosed ENKTL due to its high efficacy yet low toxicity, and clinical stage has an important effect on CR and OS.

Abstract
Sphingosine 1-phosphate (S1P) is involved in a variety of cellular responses including microglial activation and polarization. However, the impacts of S1P on ischemia-induced microglial activation and polarization remain unclear. In the present study, Sprague-Dawley rats were selected for middle cerebral artery occlusion (MCAO) establishment and treated with S1P analog FTY720 (0.5, 1, 2 mg/kg) for 24 h. The impacts of FTY720 on oxygen-glucose deprivation (OGD)-induced microglial polarization were examined in the primary cultured microglia. FTY720 treatment could prevent ischemia-induced brain injury and neurological dysfunction, also decrease the levels of IL-1β and TNF-α and promote M2 microglial polarization in rats. Further, we found that FTY720 inhibited the expressions of M1 markers, but increased the expressions of M2 markers in the OGD-insulted microglia. And FTY720 could enhance the phagocytic function of microglia. The sphingosine kinase 1/2 (SphK1/2) or the Sphk2 inhibitor could prevent the M1 to M2 phenotype shift improved by FTY720, but the Sphk1 inhibitor failed to affect the roles of FTY720. Furthermore, the Sphk1/2 or Sphk2 inhibitor promoted the activities of histone deacetylase (HDAC1) and inhibited the histone acetylation of the Krüppel-like factor 4 (KLF4) promoter regions, indicating that intra-nuclear pFTY720 inhibited HDAC1 activations and prevented KLF4 to interact with HDAC1, and thereby suppresses KLF4 deacetylation. Therefore, our data reveals that intra-nuclear SphK2-S1P axis might facilitate the transformation of microglial polarization from M1 to M2 phenotype, which might be intra-nuclear regulatory mechanisms of FTY720-prevented neuroinflammation.

Abstract
An estimated 240 million are chronically infected with hepatitis B virus (HBV), which can lead to liver disease, cirrhosis, and hepatocellular carcinoma. Currently, HBV treatment options include only nucleoside reverse transcriptase inhibitors and the immunomodulatory agent interferon alpha, and these treatments are generally not curative. New treatments with novel mechanisms of action, therefore, are highly desired for HBV therapy. The viral core protein (Cp) has gained attention as a possible therapeutic target because of its vital roles in the HBV life cycle. Several classes of capsid assembly effectors (CAEs) have been described in detail, and these compounds all increase capsid assembly rate but inhibit HBV replication by different mechanisms. In this study, we have developed a thermal shift-based screening method for CAE discovery and characterization, filling a much-needed gap in high-throughput screening methods for capsid-targeting molecules. Using this approach followed by cell-based screening, we identified the compound HF9C6 as a CAE with low micromolar potency against HBV replication. HF9C6 caused large multicapsid aggregates when capsids were assembled in vitro and analyzed by transmission electron microscopy. Interestingly, when HBV-expressing cells were treated with HF9C6, Cp was excluded from cell nuclei, suggesting that this compound may inhibit nuclear entry of Cp and capsids. Furthermore, mutational scanning of Cp suggested that HF9C6 binds the known CAE binding pocket, indicating that key Cp-compound interactions within this pocket have a role in determining the CAE mechanism of action.

Abstract
The leading cause of death in systemic lupus erythematosus (SLE) patients is infection. The objective of this study was to evaluate the distribution of lymphocyte subsets in untreated SLE patients with infections. This was a cross-sectional study. Data from January 2017 to May 2018 were collected. Flow cytometry was used to measure the peripheral lymphocyte subsets including CD3+T cells, CD4+T cells, CD8+T cells, CD19+B cells, CD3-CD16+CD56NK cells, and CD3+CD16+CD56NKT cells in 25 healthy controls and 52 treatment-naive SLE patients, among whom 13 were complicated with infections. Association between the lymphocyte subsets and infections was further analyzed. SLE patients with infections (n=13) showed a significantly higher incidence rate of fever (84.6 vs 28.2%) and serositis (84.6 vs 23.1%), increased level of erythrocyte sedimentation rate (60.5±30.1 vs 37.4±27.1 mm/h), serum C-reactive protein (CRP) (102.7±94.9 vs 9.4±14.9 mg/L), procalcitonin (PCT) (1.07±0.08 vs 0.16±0.13 μg/L), and lower blood hemoglobin (Hb) (93.0±20.5 vs 110.4±16.0 g/L) level compared with non-infection patients (n=39) (all P<0.05). In comparison with non-infectious SLE patients (387.9±261.6/μL), CD4+T cells count decreased significantly in infectious SLE patients (217.8±150.4/μL) (P<0.05), and it was negatively correlated with infection-related indicators including PCT (r=-0.573, P=0.041) and CRP (r=-0.596, P=0.032) levels. Our findings suggested that abnormalities of peripheral lymphocyte subsets were related to the immune disorder of lupus itself, regardless of immunosuppressive treatment. Monitoring lymphocyte subsets, especially CD4+T cells, may be helpful for identifying the presence of infection in SLE patients.

Abstract
OBJECTIVE The impact of pulmonary infection (PI) on mortality of patients with systemic lupus erythematosus (SLE) has been established. Nevertheless, the effect of risk factors in mortality remains controversial. The objective of this study is to determine the risk factors of short-term mortality among SLE patients with PI. METHOD The clinical data of 54 SLE patients with 59 episodes of PI who were hospitalized from January 2013 to May 2018 was retrospectively analyzed. Demographic data, clinical features, and outcomes were collected. Logistic regression analysis was carried out to determine the independent predictors of 60-day mortality during hospitalization. We used receiver operating characteristics (ROC) curves to verify the indices as mortality predictors in the study patients. RESULTS There were a total of 54 patients with 59 episodes of PI. There were 12 deaths during hospitalization. In multivariate analysis, 24-hour urinary protein (24h-PRO) (odds ratio [OR]: 2.713, 95% CI: 1.234-5.965, P = 0.013), peripheral lymphocyte count (OR: 0.066, 95% CI: 0.005-0.887, P = 0.040), and serum complement 3 level (C3) (OR: 0.097, 95% CI: 0.010-0.954, P = 0.045) were associated with mortality among our cohort of SLE patients with PI. ROC curve values were 0.818 for lymphocyte count (95% CI: 0.696-0.907, P = 0.001), 0.894 for 24h-PRO (95% CI: 0.786-0.959, P < 0.001) and 0.825 for C3 (95% CI: 0.704-0.912, P = 0.001). The cut-off value of lymphocytes, 24h-PRO and C3 were 0.53 × 109 /L, 0.92 g and 0.52 g/L, respectively. CONCLUSION The presence of albuminuria, lymphopenia and low complement C3 levels were independent prognostic predictors of short-term mortality in SLE patients with PI.

Abstract
AIMS Spodoptera exigua is a serious pest of many agricultural crops. However, the bacterial communities of S. exigua are poorly studied, particularly over their entire life cycle. We aimed to study the biodiversity of the microbiota across the life cycle of S. exigua and to provide a better and obtain insight into new pest control strategies. METHODS AND RESULTS The bacterial diversity across the life cycle of S. exigua was studied using Illumina MiSeq sequencing of 16S rRNA genes. Spodoptera exigua is dominated by Proteobacteria and Firmicutes, with a total relative abundance of 90·03%. Enterococcus (24·6%), Pseudomonas (12·2%) and Asaia (45·9%) were abundant and active in eggs, while Methylobacterium (18·7%) and Halomonas (16·5%) dominated freshly eclosed larvae. The 3rd and 5th instar larvae were dominated by Enterococcus (76·3 and 62·0%). Pupal stages had the highest microbial diversity. There was no significant difference between newly emerged males and females. Symbionts of eggs were extremely similar and probably vertically transmitted by males during mating. CONCLUSIONS The result showed that the bacterial community was affected by the host developmental stages. Our results also suggest that symbionts of egg mass are probably vertically transmitted control by male spawning adults. SIGNIFICANCE AND IMPACT OF THE STUDY Our study documents the symbiont bacteria across the life cycle of S. exigua. Understanding the microbial symbionts may provide clues to develop potential biocontrol techniques against this pest.

Abstract
The function of microRNA-21-5p (miR-21) in fibroblast-like synoviocytes in RA was still unclear. In our study, we used tumor necrosis factor alpha (TNFα) (10 ng/ml) to mimic RA-FLSs and we found that normal FLS stimulated with TNFα caused the increasing expression of miR-21, a disintegrin and metalloproteinase with thrombospondin motifs 5 and matrix metalloproteinase 3, which were in accord with RA-FLSs changes. Our data showed that miR-21 overexpression significantly increased cell invasion and decreased apoptosis in FLSs. Knockdown of miR-21 in FLSs causes the opposite result. However, miR-21 may not affect the proliferation of FLSs. Meanwhile, we showed that miR-21 activated the PI3K/AKT signaling pathway to participate in RA by inhibiting PTEN expression. Taken together, our results suggested that miR-21 may play a positive role in RA and may be a promising new therapeutic target for RA.

Abstract
Objectives: The aim of this study is to assess the current situations of standard exercise treatment and predictors of non-standard exercise in Chinese patients with ankylosing spondylitis (AS). An analysis of the effect of standard exercise on health-related quality of life (HR-QoL) was also conducted.Methods: In the cross-sectional study, a total of 259 AS patients were constantly invited to participate in this study and complete the questionnaire under the researchers' supervision in a clinical setting including sociodemographic variables, clinical variables, psychological variables, and HR-QoL. Data were analyzed by Mann-Whitney U test, Chi-square test as well as multivariable analysis of Binary Stepwise Logistic Regression.Results: The data showed that just 20.5% of them could complete the standard exercise. Exercise adherence was associated with employment, educational level, marital status, place of residence, treatment of Tumor Necrosis Factor-α inhibitor, knowledge about exercise, disease duration, clinical variables, and anxiety. The HR-QoL in the group of standard exercise was better than that in the non-standard exercise group. Logistic Regression Analysis showed that lower educational level, less knowledge about benefits of exercise treatment and higher score of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were the independent risk factors of exercise treatment non-adherence.Conclusion: AS patients educated less than 9 years or with higher BASDAI score were more likely not to adhere to standard exercise treatment. Non-adherence to exercise treatment among AS patients is exceedingly common, particularly in patients without knowledge about benefits of exercise treatment. Standard exercise treatment can also improve HR-QoL of AS patients.

Abstract
This study aimed to investigate the effects of tumor necrosis factor-α (TNF-α) on systemic lupus erythematosus (SLE). The animal model of MRL/MpJ-Faslpr mice (MRL/lpr; lupus-prone mice) showed depression-like behaviors based on tail suspension, sucrose preference, and open field tests. Brain microglia were significantly activated with obvious increases in proinflammatory cytokines. In addition, in vitro experiments showed that TNF-α activated microglia by upregulating the NF-κB signaling pathway and proinflammatory cytokines. PDTC, a specific NF-κB inhibitor, effectively reduced TNF-α-mediated inflammatory signaling in microglia. These results suggest that TNF-α-induced microglial activation has a major role in neuroinflammation of SLE with depression.

Abstract
Objective:The aim of this study is to comprehensively evaluate the values of 18F-FDG PET/CT and PET in diagnosing extranodal nasal type natural killer/T cell lymphoma (ENKTL). Method:Studies about ENKTL diagnosed by 18F-FDG PET/CT and PET until June 2018 were searched in the databases such as PubMed, Embase, Cochrane, Web of Science, CNKI, CBM, VIP and Wanfang. Two reviewers independently screened literature and extracted data strictly according to included and excluded criterion, and assessed bias risk by 11 items using QUADAS-2 gulidline. Meta-analysis was performed by Revmann 5.3 and Stata 12.0 software. The pooled weighted Sentivity (Sen), Specificity (Spe), Diagnostic odds ratio (DOR) were calculated,summary receiver operator curve (SROC) and area under SROC curve (AUC) were also drawn. Result:Ten studies with 457 patients and 5 092 foci on 18F-FDG PET/CT and 4 studies with 169 patients and 384 foci on PET were finally included in our Meta-analysis.Our research showed that pooled Sen, Spe, DOR and AUC of 18F-FDG PET/CT diagnosing ENKTL were 0.97 (95%CI 0.93-0.99), 0.97(95%CI 0.88-0.99), 1 131.07(95%CI 167.77-7 625.28), 0.99(95%CI 0.98-1.00), and they were 0.81 (95%CI 0.70-0.89), 0.90(95%CI 0.66-0.98), 39.63(95%CI 6.41-244.85), 0.86(95%CI 0.82-0.89), respectively. Z test result reveled that 18F-FDG PET/CT had better diagnostic value in detecting ENKTL compared to PET: AUC=0.99(95%CI 0.98-1.00) vs AUC=0.86(95%CI 0.82-0.89), Z=2.95, P=0.003. Conclusion:In comparasion with PET, 18F-FDG PET/CT had excellent diagnostic value in detecting and staging ENKTL and may served as a non-invasive imaging in diagnosing and staging ENKTL.

Int J Rheum Dis 2018; 21:1884-1893. [PMID: 30428506 DOI: 10.1111/1756-185x.13438] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Revised: 05/07/2018] [Accepted: 10/18/2018] [Indexed: 12/12/2022]
Abstract
OBJECTIVE The purpose of this meta-analysis was to systematically review the literature to evaluate the impact of systemic sclerosis (SSc) on the health-related quality of life (HRQoL) assessed by the Medical Outcomes Short-Form-36 questionnaire (SF-36). METHODS A systematic literature search was performed on PubMed, Web of Science and Embase until April 2017 to obtain eligible studies. Random effect model was performed to summarize the scores of each domain. Scores from the SF-36 questionnaire were used as the outcome measurements, and mean differences with 95% confidence intervals were calculated. RESULTS In total, seven studies were eligible for inclusion criteria, comprising 795 SSc patients and 1154 healthy controls. The SF-36 questionnaire score of each domain (physical function, role physical function, emotional role function, vitality, mental health, social function, body pain, general health) was lower in SSc patients than in healthy controls, meanwhile, physical component scale (PCS) and mental component scale (MCS) scores were all lower in patients with SSc than in healthy controls. Likewise, pooled mean scores of PCS and MCS ranged from 31.20 to 52.80, 37.40 to 68.30, respectively. Additionally, the score of PCS was lower than that of MCS in SSc patients. CONCLUSIONS This meta-analysis showed that SSc patients had lower HRQoL than healthy controls, and SSc had negative influence on the HRQoL of patients. This indicates that clinical workers should pay more attention to SSc patients' HRQoL, so as to improve global health of patients with SSc.

Abstract
RESEARCH QUESTION What is the role of mitochondrial DNA (mtDNA) in the pathogenesis of non-obstructive azoospermia (NOA)? DESIGN mtDNA genome sequencing followed by an independent population validation were performed in 628 NOA cases and 584 healthy controls. Antioxidant capacity of serum was evaluated in 54 randomly selected cases out of 536 and 49 out of 489 controls. RESULTS In the screening stage, 13 mtDNA haplogroups (hg) were ascertained, and 10 susceptible variants were observed. In the validation stage, hg M8* in individuals was found to be associated with increased risk of NOA [odds ratio (OR) 2.61, 95% confidence interval (CI) 1.47-4.61] (P=0.001). Unexpectedly, the frequency of m.8684C>T, the defining marker for hg M8a, was also higher in NOA (OR 4.14, 95% CI 1.56-11.03) (P=0.002). Subsequently, the frequency distributions were compared among the sub-hg of hg M8* (including hg M8a, C and Z) and, intriguingly, no significance was found in hg C and Z. Additionally, the level of total antioxidant capacity was significantly decreased (P<0.05) compared with the control group. CONCLUSIONS hg M8a background in general played an active role in the penetrance of 8684C>T in NOA, and mtDNA genetic variants (causing low antioxidant levels) might increase mtDNA damage and impair normal spermatogenesis.

Abstract
OBJECTIVE The primary purpose of the present study was to survey the quality of life (QoL) in primary Sjögren's syndrome (pSS) and to analyze the relationships between disease activity, anxiety/depression, fatigue, pain, age, oral disorders, impaired swallowing, sicca symptoms, and QoL. PATIENTS AND METHODS A survey was conducted on 185 pSS patients and 168 healthy individuals using the Short Form 36 health survey for QoL. Disease activity was assessed using the European League Against Rheumatism Sjögren's Syndrome Disease Activity Index. We examined these data using independent samples t-tests, Mann-Whitney U test, chi squared analysis, and linear regression. RESULTS The result for each domain in Short Form 36 health survey was lower in pSS patients than in healthy controls, especially the score in the dimension of role physical function. In the bivariate analysis, age, pain, fatigue, disease activity, disease complication, anxiety/depression, oral disorders, and impaired swallowing correlated with QoL. Also, in the linear regression model, pain, fatigue, disease activity, impaired swallowing, and anxiety/depression remained the main predictors of QoL. CONCLUSION pSS patients had a considerably impaired QoL compared to the controls, and pSS could negatively affect the QoL of patients. Measuring QoL should be considered as a vital part of the comprehensive evaluation of the health status of pSS patients, which could contribute some valuable clues in improving the management of disease and treatment decisions.

Antagonizing peroxisome proliferator-activated receptor γ facilitates M1-to-M2 shift of microglia by enhancing autophagy via the LKB1-AMPK signaling pathway. Aging Cell 2018; 17:e12774.

Abstract
Microglia‐mediated neuroinflammation plays a dual role in various brain diseases due to distinct microglial phenotypes, including deleterious M1 and neuroprotective M2. There is growing evidence that the peroxisome proliferator‐activated receptor γ (PPARγ) agonist rosiglitazone prevents lipopolysaccharide (LPS)‐induced microglial activation. Here, we observed that antagonizing PPARγ promoted LPS‐stimulated changes in polarization from the M1 to the M2 phenotype in primary microglia. PPARγ antagonist T0070907 increased the expression of M2 markers, including CD206, IL‐4, IGF‐1, TGF‐β1, TGF‐β2, TGF‐β3, G‐CSF, and GM‐CSF, and reduced the expression of M1 markers, such as CD86, Cox‐2, iNOS, IL‐1β, IL‐6, TNF‐α, IFN‐γ, and CCL2, thereby inhibiting NFκB–IKKβ activation. Moreover, antagonizing PPARγ promoted microglial autophagy, as indicated by the downregulation of P62 and the upregulation of Beclin1, Atg5, and LC3‐II/LC3‐I, thereby enhancing the formation of autophagosomes and their degradation by lysosomes in microglia. Furthermore, we found that an increase in LKB1–STRAD–MO25 complex formation enhances autophagy. The LKB1 inhibitor radicicol or knocking down LKB1 prevented autophagy improvement and the M1‐to‐M2 phenotype shift by T0070907. Simultaneously, we found that knocking down PPARγ in BV2 microglial cells also activated LKB1–AMPK signaling and inhibited NFκB–IKKβ activation, which are similar to the effects of antagonizing PPARγ. Taken together, our findings demonstrate that antagonizing PPARγ promotes the M1‐to‐M2 phenotypic shift in LPS‐induced microglia, which might be due to improved autophagy via the activation of the LKB1–AMPK signaling pathway.

Abstract
Hepatitis A virus (HAV) is a major cause of acute viral hepatitis, which can lead to severe cases and acute liver failure. A 41-year-old Chinese military officer of the United Nations peacekeeping forces in South Sudan manifested fever, jaundice and coagulation dysfunction. The patient initially had a negative anti-HAV IgM antibody test result but a positive anti-HAV-IgM antibody test result five days after his alanine aminotransferase (ALT) levels peaked. He was given telemedicine consultation and was transferred to a Chinese military hospital specialising in infectious diseases for treatment of severe acute HAV infection. The peak ALT, aspartate aminotransferase, total bilirubin and international standard ratio were 5410 U/L, 3475 U/L, 225.1 µmol/L and 2.12 during hospitalisation, respectively. Military personnel undergoing missions in areas with high prevalence of HAV should be tested for previous HAV infection before departure if they have not been previously vaccinated. If negative results are obtained, they should be vaccinated. Anti-HAV-IgM examination should be repeated after the first negative test result is obtained to eliminate the effects of a window period if a clinical suspicion exists. If a life-threatening case of HAV infection is present, the patient should be transported to a base military hospital specialising in infectious diseases for treatment.

Abstract
Rheumatism is a group of diseases, most of which are autoimmune diseases, that violate joints, bones, muscles, blood vessels and related soft tissue. As is well known, cytokines play a role in the pathogenesis of several rheumatic diseases, such as rheumatoid arthritis, spondyloarthritides, and systemic lupus erythematosus. Recently, the role of interleukin-4 (IL-4), which may participate in the mechanism of rheumatism, have been discovered. It is reported that IL-4 takes part in the regulation of T cell activation, differentiation, proliferation, and survival of different T cell types. IL-4 also has an immunomodulatory effect on B cells, mast cells, macrophages, and many cell types. A review of the literature on functions of IL-4 in rheumatic diseases is presented.
