RESUMEN

Tripterygium wilfordii Hook.f.(TwHF) is one of the most effective traditional Chinese herbal medicines against rheumatoid arthritis. As the representative agents of TwHF, Tripterygium Glycoside Tablets(TGT) and Tripterygium wilfordii Tablets(TWT) were included as Class A drugs in the 2019 edition of Medicine Catalogue for National Basic Medical Insurance, Injury Insurance and Maternity Insurance, and TGT was also included in 2018 edition of National Essential Drug List and 2015 edition of Chinese Pharmacopoeia. However, it is difficult to grasp the specific clinical applications of TGT and TWT. Side effects occur from time to time. The curative effect is uneven in patients. And the package inserts of TGT and TWT are not described in details. In order to standardize the clinical application of Tripterygium wilfordii preparations, 38 authoritative units and 48 well-known experts in rheumatoid immunology clinical department, drug supervision and management, pharmacy and evidence-based medicine research fields jointly developed Tripterygium Glycoside Tablets and Tripterygium wilfordii Tablets Medication Guide for reference in clinical application, teaching and scientific research. The guideline followed the "evidence-based, consensus-assisted and experience-based" principles to form "recommendations" for the evidence supported ones, and form "consensus suggestions" for those without evidence support by using nominal group method. In this way, the medication recommendations on function, usage and dosage, drug combinations, precautions, efficacy, safety and other aspects of TGT and TWT can be provided. The application of this Guide will help to avoid or reduce the adverse reactions of T. wilfordii preparations, enhance the efficacy and reduce the cost of medicine, with certain demonstration and promotion values to improve the rational use level of traditional Chinese medicine.

RESUMEN

OBJECTIVES: To investigate the role of cytokeratin-19 fragment (CYFRA21-1) in cervical lesions screening in high-risk hu-man papillomavirus (HR-HPV) infected women. MATERIAL AND METHODS: The study was a retrospective study. First, the results of CYFRA21-1, cytology (TCT), and HR-HPV examinations of 1039 outpatients from gynecology department in Tumor Hospital Affiliated to Xinjiang Medical University were collected. Then, the data was analyzed using a series of statistical methods. RESULTS: There was a correlation between CYFRA21-1 levels and HPV-DNA load in HR-HPV infected women (rs = 0.711, p = 0.015). CYFRA21-1 levels and positive rate increased along with deepening of cervical cell lesions. In HR-HPV infected women, there was a statistically significant difference (t = 6.022, p < 0.001) in CYFRA21-1 levels between the group with cytological lesions (4.87 ± 1.58 ng/mL) and the group with normal cytology (2.52 ± 0.96 ng/mL). Positive rates of CYFRA21-1 in the two groups were 62.06% and 7.83%, respectively, and also exhibited statistically significant differences (χ2 = 74.624, p < 0.001). When diagnosing cytological lesions via CYFRA21-1 in HR-HPV infected women, sensitivity was 62.07%, specificity was 92.17%, positive predictive value was 88.89%,negative predictive value was 70.67%. Compared to CYFRA21-1 negative women, cytological lesions were detected 19.273 times more often in CYFRA21-1 positive women. CONCLUSION: CYFRA21-1 could provide a reference idea for further diagnosis of women who are infected with HR-HPV but whose cytology is normal.

RESUMEN

Non-alcoholic fatty liver disease (NAFLD) is considered to be a manifestation of liver metabolic damage and is related to insulin resistance and genetic susceptibility. Inflammation mediated by Kupffer cells (KCs) is of critical importance to the development of NAFLD. The primary role of KCs in NAFLD is considered to be the perturbation of the C-Jun N-terminal kinase (JNK) and nuclear factor-kappa B (NF-κB) pathways as a result of lipopolysaccharide (LPS) recognition by Toll-like receptor 4 (TLR4). Simultaneously, the activation of NF-κB, as mediated by oxidative and endoplasmic reticulum (ER) stress and free fatty acid (FFA) or free cholesterol (FC) crystal formation, heavily relies on NF-κB regulatory factors and TLR4. Additionally, the imbalance of certain pro-inflammatory cytokines and chemokines released by innate immunity is deemed to promote the steatosis of hepatocytes. In conclusion, this review indicates that the inflammatory and oxidative stress of KCs play a significant role in the development of NAFLD.

RESUMEN

Ankylosing spondylitis (AS) is an autoimmune disease, and the imbalance of peripheral tolerance is involved in its pathogenesis. Importantly, the negative signal of activated T cells plays a crucial role in the balance of peripheral tolerance. It has been postulated that human protein tyrosine phosphatase nonreceptor 22 (PTPN22) and cytotoxic T-lymphocyte antigen-4 (CTLA-4) genes encode proteins that are actively involved in regulating T-cell activation. Therefore, we evaluated the effects of PTPN22 and CTLA-4 genotypes on the occurrence of AS. Genetic polymorphisms of PTPN22 -1123G/C and CTLA-4 +49A/G were identified by polymerase chain reaction for 391 AS patients and 391 healthy controls. Subjects with PTPN22 CC and GC genotypes had a greater risk of AS occurrence than those with PTPN22 GG genotype [relative risk = 1.39, 95 % confidence interval (95 % CI) 1.03-1.88]. Further, subjects with PTPN22 CC/CTLA-4 AA or PTPN22 GC/CTLA-4 AA genotypes had 1.90-fold (95 % CI 1.02-3.49) greater risk of AS development than those with other combinations of PTPN22 and CTLA-4 genotypes. Our findings indicated that PTPN22 -1123G/C and CTLA-4 +49A/G genetic polymorphisms have a combined effect on the development of AS.

RESUMEN

This study delves into the impact of formal institutions on stock market volatility within a selection of emerging economies. Specifically, it examines the role that formal institutions play in shaping this volatility. To accomplish our goal, we analyze panel data from 46 emerging nations spanning the years 2000-2019, utilizing system generalized method of moments (GMM), as well as random and fixed effect models for our estimations. The findings of this research validate the existence of a significant association between formal institutions and stock market volatility. Likewise, through dynamic panel estimation, we discover that formal institutions such as property rights, financial freedom, and government regulations have a notable negative effect on stock market volatility. Consequently, this study implies that formal institutions play a crucial role in reducing stock market volatility in emerging economies, fostering their development. The insights gained from this research encourage policymakers to view formal institutions as key influencers of stock market volatility. These results offer valuable guidance for emerging nations.

RESUMEN

From the perspective of health economics, the evaluation of drug-related cost effectiveness and clinical utility is crucial. We conducted a cost-utility analysis of two first-line drugs, tenofovir alafenamide (TAF) and entecavir (ETV), in the treatment of chronic hepatitis B (CHB) patients. We performed inverse probability of treatment weighting (IPTW) to match the independent variables between the two treatment groups. The incremental cost effectiveness ratio (ICER) of the two treatment groups was simulated using a decision tree with the Markov annual-cycle model. A total of 54 patients treated with TAF and 98 with ETV from January 2016 to December 2020 were enrolled. The total medical cost in the TAF group was NT$76,098 less than that in the ETV group, and TAF demonstrated more effectiveness than ETV by 3.19 quality-adjusted life years (QALYs). When the time horizon was set at 30 years, the ICER of the TAF group compared with the ETV group was -NT$23,878 per QALY, suggesting more cost savings for TAF. Additionally, with the application of TAF, over NT$366 million (approximately US$12 million) can be saved annually. TAF demonstrates cheaper medical costs and more favorable clinical QALYs than ETV. To balance health insurance benefits and cost effectiveness, TAF is the optimal treatment for CHB.

RESUMEN

BACKGROUND: A low expression of metallothionein (MT) has been observed in liver cancer. Such a phenomenon might be influenced by oxidative stress, thus resulting in the cells being more susceptible to DNA damage and apoptotic death. In particular, oxidative stress induced by cigarette smoking might affect MT-1 expression. We designed a hospital-based case-control study to evaluate the effects of MT-1 genotypes and smoking on hepatocellular carcinoma (HCC) occurrence. METHODS: A total of 102 HCC patients and 191 matched healthy control subjects were recruited, and epidemiological information was collected. Six genotypes of MT-1 were determined with TaqMan single-nucleotide polymorphism genotyping assays. RESULTS: Individuals possessing MT-1 rs8052394 A, rs964372 G, and rs8052334 T alleles as well as engaging in cigarette smoking had increased risks of HCC; these alleles also had higher linkage disequilibrium. Carriers with MT-1 rs8052394, rs964372, and rs8052334 A-G-T haplotype had a 2.25-fold (95 % confidence interval [CI] 1.46-3.26) risk for HCC development than the control group (A-C-T, the most common haplotype). Compared to nonsmokers with other haplotypes (A-C-T, G-G-C, A-G-C, G-G-T, G-C-T, and G-C-C), nonsmokers with A-G-T haplotype had a 1.93-fold (95 % CI 1.01-3.71) increased risk, and smokers with other haplotypes had a 3.66-fold (95 % CI 1.78-7.54) increased risk, whereas smokers carrying the A-G-T haplotype had the highest risk (matched relative risk 6.72; 95 % CI 2.86-15.79) of developing HCC. CONCLUSIONS: The MT-1 A-G-T haplotypes are associated with increased risk of HCC, especially in those who smoke.

RESUMEN

BACKGROUND: Environmental tobacco smoke (ETS) is a risk factor for asthma. Importantly, cigarette smoke can decrease the adherence of epithelial cells and increase detachment. The adhesion molecule E-cadherin (CDH1) has an essential role in the formation of epithelial junction. Turnover of the extracellular matrix, which is characterized by airway remodeling, depends on the imbalance between matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinase (TIMPs). OBJECTIVE: To evaluate the effects of ETS exposure and CDH1, MMP-3, and TIMP-1 genetic polymorphisms on childhood asthma. METHODS: The CDH1 C-160A, MMP-3 -1171, and TIMP-1 T372C genotypes were identified by polymerase chain reaction in 299 asthmatic children and 383 healthy controls. RESULTS: More ETS exposure (>5 vs 0 cigarettes/day; odds ratio [OR], 1.45; 95% confidence interval [CI], 1.05-2.01) and the presence of CDH1 AA/CA genotypes (OR, 1.53; 95% CI, 1.08-2.17) were associated with childhood asthma. Compared with children with less ETS exposure (0-5 cigarettes/day) and the CDH1 CC genotype, those with less ETS exposure and the CDH1 AA/CA genotypes and those with more ETS exposure and the CDH1 CC genotype had a moderate risk of asthma. The greatest risk for asthma was in children with more ETS exposure and the CDH1 AA/CA genotypes (OR, 3.03; 95% CI, 1.81-5.06), and this interaction between CDH1 polymorphism and ETS exposure was significant. In addition, asthma cases with more ETS exposure or the CDH1 AA/CA genotypes had obviously increased eosinophil counts. CONCLUSION: Susceptible CDH1 genotypes might modulate the development of asthma, especially for children exposed to ETS.

RESUMEN

Heavy metals, including arsenic and lead, may lead to cellular oxidative damage that is linked to hypertension. Manganese superoxide dismutase (MnSOD) is a scavenger of reactive oxygen species, and 8-oxoguanine DNA glycosylase (OGG1) is the major glycosylase that repairs DNA lesions. Interestingly, whether there is an elevated risk of hypertension with arsenic or lead exposure in individuals with genetic variations in MnSOD or OGG1 has not yet been investigated. Questionnaires were administered to 240 Taiwanese rural residents. Blood pressure and biochemical indicators were assessed in each subject. Urinary levels of arsenic and lead were measured with atomic absorption spectrometry; and MnSOD and OGG1 genotypes were identified via polymerase chain reaction. There was a dose-response relationship between urinary arsenic levels and risk of hypertension (P = 0.021, test for trend). However, there was no association between urinary lead levels and hypertension risk. Individuals with high urinary arsenic levels and the MnSOD Val-Ala/Ala-Ala genotypes had a greater risk of hypertension than those with low urinary arsenic levels and the MnSOD Val-Val genotype (odds ratio [OR] = 4.2, 95% confidence interval [CI] = 1.7-10.3). Subjects with a high urinary arsenic level and the OGG1 Cys-Cys genotype also had a greater risk of hypertension than those with a low urinary arsenic level and the OGG1 Ser-Ser/Ser-Cys genotypes (OR = 3.4, 95% CI = 1.1-10.7). Thus, both MnSOD and OGG1 genotypes may be prone to an increased risk of hypertension associated with arsenic exposure.

RESUMEN

Triarylamine end-capped-functionalized arylene-imidazole derivatives were synthesized from readily accessible, inexpensive precursors and employed as hole transporting materials (HTMs) in perovskite solar cells (PSCs). All the HTMs displayed high thermal decomposition temperatures (>410 °C), which is beneficial for realizing stable PSC devices. In addition, the new HTMs show appropriate energy level alignment with the perovskite layer, ensuring efficient hole transfer from perovskites to HTMs. Interestingly, PSCs fabricated with the triarylamine-functionalized imidazolyl-capped bithiophene molecule (DImBT-4D) as the HTM exhibited the best power conversion efficiency of 20.11%, comparable to that of the benchmark HTM spiro-OMeTAD, prompting it be a prospective candidate for large-scale PSC applications.

RESUMEN

OBJECTIVES: Osteoporosis is one of the recognized features of AS. It is known that RANK ligand (RANKL), which binds to RANK, can cause the activation of bone resorption. Osteoprotegerin (OPG) also competes with RANK by binding to RANKL and inhibiting bone absorption. Therefore, we designed a case-control study to evaluate the association between occurrence and clinical features of AS and RANK, RANKL and OPG genetic polymorphisms. METHODS: A total of 330 AS patients and 330 age- and gender-matched controls were recruited. PCR-restriction fragment length polymorphism was applied to identify RANK C575T, RANKL C-290T and OPG G1181C genotypes. RESULTS: OPG GG genotype carriers had an elevated risk of AS compared with those with the GC and CC genotypes (matched odds ratio 1.74; 95% CI 1.26, 2.40). Age of symptom onset and frequency of peripheral arthritis significantly differed among AS patients by OPG G1181C genotypes. HLA-B27(+) patients with the OPG C allele had the earliest age of symptom onset [mean (s.d.) 26.6 (9.6) years], followed by HLA-B27(+) patients with the OPG G allele [32.6 (12.2) years], HLA-B27(-) patients with the OPG G allele [38.1 (13.6) years] and HLA-B27(-) patients with the OPG C allele [38.6 (9.8) years]. CONCLUSION. OPG G1181C polymorphism may be associated with AS development and clinical manifestations.

RESUMEN

OBJECTIVES: There is a known association of imbalanced peripheral tolerance and autoimmune diseases. The binding of programmed cell death 1 (PD-1) with its ligands 1 and 2 (PD-L1 and PD-L2) inhibits T-cell proliferation through a negative signal via recruitment of src homology 2-domain-containing tyrosine phosphatase 2. Therefore we evaluated the effect of the PD-1, PD-L1 and PD-L2 genotypes on the occurrence of AS in a population of Taiwanese patients. METHODS: Genetic polymorphisms of PD-1 G-536A, PD-L1 A8923C and PD-L2 C47103T were identified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for 330 AS patients and 330 healthy controls who were matched by age and gender. RESULTS: Subjects with the PD-1 GG genotype [matched relative risk (RR(m)) 1.78; 95% CI 1.13, 2.81] and the GA genotype (RR(m) 1.59; 95% CI 1.09, 2.31) had significantly greater risk for AS than those with the AA genotype. Subjects with the PD-L2 CT genotype had lower risk for AS than those with the CC genotype (RR(m) 0.01; 95% CI 0.001, 0.06). Interestingly, the combined genotypes of PD-1 G-536A, PD-L1 A8923C and PD-L2 C47103T also appear to be associated with AS development. CONCLUSIONS: Our results suggest that PD-1 G-536A, PD-L1 A8923C and PD-L2 C47103T polymorphisms are associated with the presence of AS.

RESUMEN

BACKGROUND: Guidelines are critical for facilitating cost-effective COPD care. Development and implementation in low-and middle-income countries (LMICs) is challenging. To guide future strategy, an overview of current global COPD guidelines is required. RESEARCH QUESTION: We systematically reviewed national COPD guidelines, focusing on worldwide availability and identification of potential development, content, context, and quality gaps that may hamper effective implementation. STUDY DESIGN AND METHODS: Scoping review of national COPD management guidelines. We assessed: (1) global guideline coverage; (2) guideline information (authors, target audience, dissemination plans); (3) content (prevention, diagnosis, treatments); (4) ethical, legal, and socio-economic aspects; and (5) compliance with the eight Institute of Medicine (IOM) guideline standards. LMICs guidelines were compared with those from high-income countries (HICs). RESULTS: Of the 61 national COPD guidelines identified, 30 were from LMICs. Guidelines did not cover 1.93 billion (30.2%) people living in LMICs, whereas only 0.02 billion (1.9%) in HICs were without national guidelines. Compared with HICs, LMIC guidelines targeted fewer health-care professional groups and less often addressed case finding and co-morbidities. More than 90% of all guidelines included smoking cessation advice. Air pollution reduction strategies were less frequently mentioned in both LMICs (47%) and HICs (42%). LMIC guidelines fulfilled on average 3.37 (42%) of IOM standards, compared with 5.29 (66%) in HICs (P < .05). LMICs scored significantly lower compared with HICs regarding conflicts of interest management, updates, articulation of recommendations, and funding transparency (all, P < .05). INTERPRETATION: Several development, content, context, and quality gaps exist in COPD guidelines from LMICs that may hamper effective implementation. Overall, COPD guidelines in LMICs should be more widely available and should be transparently developed and updated. Guidelines may be further enhanced by better inclusion of local risk factors, case findings, and co-morbidity management, preferably tailored to available financial and staff resources.

RESUMEN

BACKGROUND: Thrombomodulin (TM) is a key molecule mediating circulation homeostasis through its binding to thrombin. The TM-thrombin complex can activate protein C and thrombin-activatable fibrinolysis inhibitor to form a tight clot. In many cancer tissues, decrease of TM expression may correlate with cancer metastasis. However, the role of TM in hepatocellular carcinoma (HCC) progression is still unclear. METHODS: We characterized TM expression in HCC cells (HepJ5 and skHep-1 cells) using real-time polymerase chain reaction (PCR) and Western blotting. We then manipulated TM expression using both TM-specific short hairpin RNA (shRNA) and overexpressing it in HCC cells. Transwell migration assay was performed to monitor the migratory ability of HCC cells under different levels of TM expression. RESULTS: We found that TM was ectopically highly expressed in skHep-1 at both transcriptional and translational levels. After silencing TM expression in skHep-1 cells, we found that metastatic capability was dramatically increased. Conversely, overexpression of TM in HepJ5 cells decreased metastatic ability. We investigated the possible mechanism and found that decreased TM-mediated enhancement of cell migration was dependent on upregulation of ZEB1, a repressor of E-cadherin. CONCLUSIONS: TM may be a modulator of cancer metastasis in HCC. Downregulation of TM expression may increase ZEB1 and decrease E-cadherin levels.

RESUMEN

We demonstrate a novel nanolithography method based on the photocatalytic decomposition of the self-assembled monolayer (SAM) near a TiO2-coated probe. The TiO2 film was deposited on Ti-Pt coated Si probes by plasma sputtering. After annealing at 500 degrees C in air for 2 hr, the film was in the anatase phase, according to examination by Raman and X-ray diffraction spectra. Island-structured octadecyltrichlorosilane (OTS) partial monolayers on glass were used as the substrates. When the photocatalytic probe was illuminated by ultra-violet light, the modification occurred on the near OTS SAM islands. No change was observed on the exposed oxide surface between OTS islands. Without UV illumination, no modification occurred on OTS. Thus, the modification of the OTS surface is related to the photocatalytic reaction. A line width as small as 60 nm was achieved and observed by lateral force microscopy (LFM). The diffusion of reactive oxygen species were also observed from the remote photodecomposition of the OTS monolayer. These results should be beneficial to the development of hierarchically constructed nanolithography.

RESUMEN

BACKGROUND: The Uygur is the fifth most populous ethnic group in China. Compared to other Chinese population, cervical cancer in them had high incidence, and HPV infection also was particular. Their HPV integration situation has never been reported. We aimed to investigate the integration situation of 20 subtypes of HPV gene into host cell genome in Chinese Uygur cervical cancer patients; meanwhile, we explored the influence of gene integration on PD-L1 expression. METHODS: 40 frozen Chinese Uygur cervical cancer specimens with positive HPV infection were obtained from the cancer prevention and treatment institute of Tumor Hospital Affiliated to Xinjiang Medical University. The integration situation of HPV gene into host cell genome was detected by Agilent SureSelect™ Target Enrichment Chip and Next-Generation Sequencing. The related genes were analyzed by GO functional annotation and KEGG pathway enrichment. The expression levels of PD-L1 in cancer cells were tested by immunohistochemical assay (IHC). Meanwhile, the relationship between PD-L1 levels in cancer cells and gene integration were analyzed. RESULTS: The HPV multiple infection rate by HIVID was as high as 92.5%, much higher than 35.0% by the commercial kit (P < 0.05). There were 13423 integration events in 40 specimens, involving 6867 human genes. These integration events were distributed on all human chromosomes, and chromosome 19 had the excessive concentration phenomenon of integration events. There were some integration hotspots in human genome such as PPP1R37, HECW2, EMBP1, ANKRD50, SPTBN4, LINC00895, LYRM4-AS1, LINC00374, RBFOX1, CSMD1, CDH13, and KLHL4. Insertion breakpoints can be found in all gene regions of the HPV genome. The actual observation of the integration times of E1 and E6 was much higher than the expected value, while the actual observation times of E5 were much lower than the expected value. The result of GO functional analysis showed that binding molecular function and cellular process biological process were the main ways to influence the cell biological behavior of HPV gene integration. The enrichment pathway analysis of KEGG showed that pathways in cancer were the most important enrichment pathways involved in the genomic integration of HPV. The positive PD-L1 rate was 62.5%. Logistic regression analysis showed that 9p24.1 existing integration sites and the number of all gene integration were risk factors for PD-L1 expression (odds ratio 17.313 and 1.012; 95% confidence interval 1.691-177.213 and 1.001-1.023). Conclusions and Relevance. Most high-frequency sites of HPV integration in Chinese Uygur cervical cancer are related to cancer progression, and the gene integration hotspots may be potential HPV carcinogenic targets. The problem of multiple HPV infection in Chinese Uygur cervical cancer patients should be paid attention. L1 and E6 genes are inapposite as the target gene of commercial HPV type detection kit, because of high-frequency breakpoints in these genes. The gene integration especially the integration existing on 9p24.1 could affect the expression level of PD-L1.

RESUMEN

OBJECTIVES: There is growing recognition around the importance of multimorbidity in low-income and middle-income country (LMIC) settings, and specifically the need for pragmatic intervention studies to reduce the risk of developing multimorbidity, and of mitigating the complications and progression of multimorbidity in LMICs. One of many challenges in completing such research has been the selection of appropriate outcomes measures. A 2018 Delphi exercise to develop a core-outcome set for multimorbidity research did not specifically address the challenges of multimorbidity in LMICs where the global burden is greatest, patterns of disease often differ and health systems are frequently fragmented. We, therefore, aimed to summarise and critically review outcome measures suitable for studies investigating mitigation of multimorbidity in LMIC settings. SETTING: LMIC. PARTICIPANTS: People with multimorbidity. OUTCOME MEASURES: Identification of all outcome measures. RESULTS: We present a critical review of outcome measures across eight domains: mortality, quality of life, function, health economics, healthcare access and utilisation, treatment burden, measures of 'Healthy Living' and self-efficacy and social functioning. CONCLUSIONS: Studies in multimorbidity are necessarily diverse and thus different outcome measures will be appropriate for different study designs. Presenting the diversity of outcome measures across domains should provide a useful summary for researchers, encourage the use of multiple domains in multimorbidity research, and provoke debate and progress in the field.

RESUMEN

Objective:To investigate the level change of cytokines in patients with Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis (EBV-HLH).Methods:A retrospective case control study was conducted. The clinical data of 65 patients with EBV-HLH, 30 patients with infectious mononucleosis (IM) (IM group) and 40 patients with non-EBV infection-associated hemophagocytic lymphohistiocytosis (non-EBV-HLH group) who admitted to Tongji Hospital,Tongji Medical College of Huazhong University of Science and Technology from February 2022 to February 2023 were retrospectively analyzed. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of the interleukin (IL)-6, IL-2, IL-10, IL-8, IL-1β, tumor necrosis factor-α (TNF-α) and interferon γ (IFN-γ) in serum samples of patients in the above 3 groups. The cytokines levels in EBV-HLH group were compared with those in IM group and non-EBV-HLH group, respectively.Results:The cytokines levels of IL-6, IL-2, IL-10, IL-8, IL-1β, TNF-α and IFN-γ in EBV-HLH group were higher than those in the non-EBV-HLH group, and the differences were statistically significant (all P < 0.05). The cytokines levels of IL-2, IL-10 and IFN-γ in EBV-HLH group were higher than those in IM group, and the differences were statistically significant (all P < 0.05). Conclusions:The cytokines levels of IL-6, IL-2, IL-10, IL-8, IL-1β, TNF-α, IFN-γ are increased in EBV-HLH patients, which may play an important role in the development and progression of EBV-HLH.
