Excessive and persistent inflammatory responses are a potential pathological condition that can lead to diseases of various systems, including nervous, respiratory, digestive, circulatory, and endocrine systems. Cannabinoid type 2 receptor(CB2R) belongs to the G protein-coupled receptor family and is widely distributed in immune cells, peripheral tissues, and the central nervous system. It plays a role in inflammatory responses under various pathological conditions. The down-regulation of CB2R activity is an important marker of inflammation and and CB2R modulators have been shown to have anti-inflammatory effects. This study explored the relationship between CB2R and inflammatory responses, delved into its regulatory mechanisms in inflammatory diseases, and summarized the research progress on CB2R modulators from plants other than cannabis, including plant extracts and monomeric compounds, in exerting anti-inflammatory effects. The aim is to provide new insights into the prevention and treatment of inflammatory diseases.

OBJECTIVES: To investigate the expression and significance of jumonji domain-containing protein 2B (JMJD2B) and hypoxia-inducible factor-1α (HIF-1α) in non-Hodgkin's lymphoma (NHL) tissues in children. METHODS: Immunohistochemistry was used to detect the expression of JMJD2B and HIF-1α in lymph node tissue specimens from 46 children with NHL (observation group) and 24 children with reactive hyperplasia (control group). The relationship between JMJD2B and HIF-1α expression with clinicopathological characteristics and prognosis in children with NHL, as well as the correlation between JMJD2B and HIF-1α expression in NHL tissues, were analyzed. RESULTS: The positive expression rates of JMJD2B (87% vs 21%) and HIF-1α (83% vs 42%) in the observation group were higher than those in the control group (P<0.05). The expression of JMJD2B and HIF-1α was correlated with serum lactate dehydrogenase levels and the risk of international prognostic index in children with NHL (P<0.05). The expression of JMJD2B was positively correlated with the HIF-1α expression in children with NHL (r_s=0.333, P=0.024). CONCLUSIONS JMJD2B and HIF-1α are upregulated in children with NHL, and they may play a synergistic role in the development of pediatric NHL. JMJD2B can serve as a novel indicator for auxiliary diagnosis, evaluation of the severity, treatment guidance, and prognosis assessment in pediatric NHL.

To analyze the research status of acupuncture and moxibustion for cancer at home and abroad in the past 45 years by using bibliometric and scientific knowledge map methods，and explore the development trends in future. The literature of acupuncture and moxibustion for cancer was retrieved from CNKI and Web of Science (WOS) till December 31, 2020 since the database establishment, and CiteSpace and VOSviewer software were used to perform visual map analysis through cooperation network, keyword co-occurrence, keyword timeline, keyword emergence and other methods. Totally, 1 585 literature in CNKI and 1 564 literature in WOS were included, and the annual publication amount showed a fluctuating upward trend. Cooperation between countries was centered on China and the United States, and there was relatively little cooperation among different institutions. The analysis of keyword and cited literature showed that researches focused on the control of acupuncture and moxibustion therapy on cancer complications and adverse reactions of western medicine. The main research types in WOS were systematic review and randomized controlled trial (RCT), while in CNKI was review, depth studies on mechanism of acupuncture and moxibustion for cancer were rare. The concern about the quality of life of cancer patients may become research emphasis in the field of acupuncture and moxibustion for cancer in future, and the research scope tends to integrative and holistic oncology.

Objective: To investigate the clinical features of children with chronic nonbacterial osteomyelitis (CNO), and raise awareness among clinicians. Methods: In this retrospective study, 18 patients with CNO who were diagnosed in Children's Hospital of Fudan University from January 2015 to December 2021 were included. Results: Eighteen children with CNO (12 males, 6 females) were identified. Their age at onset was 9 (5, 11) years, the delay in diagnosis was 2 (1, 6) months, and follow-up-was 17 (8, 34) months. The most common symptoms were fever in 14 children, as well as bone pain and (or) arthralgia in 14 children. In terms of laboratory results, normal white blood cell counts were observed at onset in 17 patients; increased erythrocyte sedimentation rate (ESR) in all patients; increased C reactive protein (CRP) over the normal value in 14 patients. Of the 18 patients, 2 had positive antinuclear antibodies, while none had positive human leukocyte antigen-B27 or rheumatoid factor. Imaging examination revealed that all the patients had symmetrical and multifocal skeletal lesions. The number of structural lesions detected by imaging investigation was 8 (6, 11). The most frequently affected bones were tibia in 18 patients and femur in 17 patients. Bone biopsy was conducted in 14 patients and acute or chronic osteomyelitis manifested with inflammatory cells infiltration were detected. Magnetic resonance imaging (MRI) found bone lesions in all the patients and bone scintigraphy were positive in 13 patients. All the patients were treated with nonsteroidal anti-inflammatory drugs, among whom 10 cases also treated with oral glucocorticoids, 9 cases with traditional disease modifying anti-rheumatic drugs, 8 cases with bisphosphonates and 6 cases with tumor necrosis factor inhibitors. The pediatric chronic nonbacterial osteomyelitis disease activity score, increased by 70% or more in 13 patients within the initial 6-month follow-up. Conclusions: The clinical manifestations of CNO are lack of specificity. The first symptom of CNO is fever, with or without bone pain and (or) arthralgia, with normal peripheral blood leukocytes, elevated CRP and (or) ESR. Whole body bone scanning combined with MRI can early detect osteomyelitis at subclinical sites, and improve the diagnostic rate of CNO.

As a traditional Chinese medicinal material， Glycyrrhizae Radix et Rhizoma has been extensively used in various formulae. According to modern pharmacological research， it has anti-tumor， anti-inflammatory， anti-viral， liver-protecting， anti-heart failure， immunoregulatory， and anti-fibrosis effects. Caused by the interaction of various factors， cancer features complex pathogenesis. It is a global challenge and one of the main causes of death in China. Statistics show that the morbidity and mortality of malignant tumors have been on the rise， particularly for the young， which threaten the health of human beings. At the moment， radiotherapy and chemotherapy are the main countermeasures. Most clinical anti-tumor drugs demonstrate non-selective toxicity. To be specific， they damage normal cells while killing tumor cells， thus injuring vital organs. In addition， long-term medication will reduce the sensitivity of tumor cells. However， traditional Chinese medicine， which is characterized by treatment based on syndrome differentiation， multiple components， and multiple targets， is superior in the treatment of tumor. Studies have shown that the combination of anti-tumor drugs with Chinese medicine can not only enhance the anti-tumor effect but also alleviate toxicity. Therefore， it has been a research hotspot to develop anti-tumor drugs based on traditional Chinese medicine. In recent years， major headway has been made in the research on active ingreddients of Glycyrrhizae Radix et Rhizoma in anti-liver cancer， anti-breast cancer， anti-lung cancer， and anti-colon cancer and the combination with other drugs for anti-tumor. On this basis， we summarized the mechanisms of active ingredients of Glycyrrhizae Radix et Rhizoma in inducing apoptosis， interfering with cell cycle， inducing autophagy， inhibiting glycolysis， regulating immunity， and modulating miRNA and signaling pathways， as well as the combination with other drugs in anti-tumor efficiency， toxicity reduction， and sensitivity enhancement， hoping to lay a theoretical basis for the further development and clinical application of active ingredients of Glycyrrhizae Radix et Rhizoma.

Purpose: Systemic inflammatory response is a critical factor that promotes the initiation and metastasis of malignancies including pancreatic cancer (PC). This study was designed to determine and compare the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and fibrinogen-to-albumin ratio (FAR) in resectable PC and locally advanced or metastatic PC. Materials and Methods: Three hundred fifty-three patients with resectable PC and 807 patients with locally advan-ced or metastatic PC were recruited in this study. These patients were classified into a training set (n=758) and a validation set (n=402). Kaplan-Meier survival plots and Cox proportional hazards regression models were used to analyze prognosis. Results: Overall survival (OS) was significantly better for patients with resectable PC with low preoperative PLR (p=0.048) and MLR (p=0.027). Low FAR, MLR, NLR (p < 0.001), and PLR (p=0.003) were significantly associated with decreased risk of death for locally advanced or metastatic PC patients. FAR (hazard ratio [HR], 1.522; 95% confidential interval [CI], 1.261 to 1.837; p < 0.001) and MLR (HR, 1.248; 95% CI, 1.017 to 1.532; p=0.034) were independent prognostic factors for locally advanced or metastatic PC. Conclusion The prognostic roles of FAR, MLR, NLR, and PLR in resectable PC and locally advanced or metastatic PC were different. FAR showed the most prognostic power in locally advanced or metastatic PC. Low FAR was positively correlated with OS in locally advanced or metastatic PC, which could be used to predict the prognosis.
