Objective:To investigate effects of dendritic cells(DCs) pulsed with autologous hepatoma cell lysates on the immune function of the postoperative patients with hepatocellular carcinoma(HCC).Methods:DCs isolated from peripheral blood mononuclear cell of HCC patients were cultured and proliferated in vitro by using rhGM-CSF and rhIL-4,and then were pulsed with autologous hepatoma cell lysates.30 postoperative patients with HCC were randomly divided into 2 groups.15 cases were treated with dendritic cell vaccine.15 cases received only chemotherapy and were established as control group.Immune function、clinical effects in two groups of patients were compared and observed.Results: The levels of DC3~+、DC4~+/CD8~+ and NK cell in the DC vaccine group significantly increased after vaccination,while those of the control group had no significant changes.The levels of IgG、IgM、IgA in the DC vaccine group increased after vaccination,but didn't reach statistical significance.The concentration of IL-10 in the DC vaccine group significantly decreased after vaccination(P

Interferons(IFNs) are a family of glycoproteins with antiviral, antitumor, and immunomodulatory activities, classi-fied into type Ⅰ, Ⅱ, and Ⅲ based on structural and receptor specificity. Among these, type Ⅲ IFNs(IFNλs), including IFNλ1(IL-29),IFNλ2(IL-28a),andIFNλ3(IL-28b),exhibittissue-specificreceptordistribution,predominantlyexpressedinepithelialcells and select immune cells, thereby demonstrating reduced systemic side effects compared to typeⅠIFNs. Mechanistically,IFNλs exert their antiviral effects through JAK/STAT signaling pathway inducing the expression of interferon-stimulatedgenes(ISGs), and inhibit tumor cell proliferation, promote apoptosis and regulate immune responses. Recent advances inrecombinant IFNλs therapeutic development include polyethylene glycol(PEG) modified IFNλ1, a longacting formulationcurrently in phaseⅢclinical trials for hepatitis C, hepatitis D, and COVID-19. In this paper, the structures and receptors,signaling pathway and regulation, biological functions and research progress of IFNλs are summarized in order to provideinsights for the development of IFNλs related products.

Nrf2/Keap1/ARE is an important signaling pathway in maintaining the balance between peroxide and antioxidants. Once oxidative stress happened, Nrf2/Keap1/ARE would be ac-tivated to regulate the expression of downstream antioxidant pro-teins that could reduce the injury from oxidative stress and the level of oxidative stress. Recent researches show that Nrf2/Keap1/ARE signaling pathway is closely related to refractory re-spiratory diseases such as pulmonary fibrosis (PF), lung canc-er, chronic obstructive pulmonary disease (COPD), suggesting that Nrf2/Keap1/ARE signaling pathway may be a potential ther-apeutic target. This review focuses on the role of Nrf2/Keap1/ARE signaling pathway in refractory respiratory diseases in order to further understand the related mechanism and provide evidence for the diagnosis and treatment of refractory respiratory diseases.

Objective To explore the optimal immunohistochemical (IHC)diagnostic index for supraclavicular lymph node me-tastasis in lung cancer.Methods In the premise of conforming to the evidence-based medicine,the biopsy of lymph node in 135 pa-tients with supraclavicular lymph node metastasis was performed and 7 antibodies were selected to be detected.135 cases were di-vided into two classes:class A (110 cases)and B (25 cases).The class A included 14 cases of primary lesion inside the lung by the histological analysis,43 cases of primary lesion inside the lung by the cytological detection and 53.cases of primary lesion inside the lung by the radiographic analysis.The class B included 25 cases of lesion outside the lung by the histological analysis.The detecting antibodies included CK7,CK20,EMA,CEA,TTF-1,SPB and vimentin.Results The sensitivity and specificity of single antibody for deducing the primary lesion inside the lung were 90.0% and 56.0% for CK7,98.0% and 40.0% for CK20,90.9% and 4.0%for EMA,80.9% and 36.0% for CEA,62.7% and 100.0% for TTF-1,65.6% and 100.0% for SPB,and 60.9% and 60.0% for vimentin.The quadruple antibodies (CK7,CK20,TTF-1 and SPB)showed the highest sensitivity(85.0%)and highest specificity (100.0%),which made the relatively high detection rate (80.0%)of lung cancer in clinic.Conclusion Analyzing and researching the IMC results is of great significance to guide the surgical pathological practice based on the evidence-based medicine.

Objective To evaluate the quality of the randomized controlled trials (RCTs) published in two key Chineze journals on clinical nutrition.Methods The articles published in CHINESE JOURNAL OF CLIN-ICAL NUTRlTION and PARENTERAL & ENTERAL NUTRITION from 2000 to 2008 were reviewed and the RCTs were identified according to criteria of the handbook of Cochrane Collaboration.The Jadad scale was used to evalu-ate the quality of these RCTs.Results Totally 238 RCT articles were published in these two journals in this peri-od.The Jadad score of all RCT articles was 1.65±0.82.Twenty-eight articles (11.76%) were of high quality and only 5 articles (2.10%) were identified 5 points.There were some problems in the RCTs design,conduction and analyses included unclear randomization methods,poor comparison,lack of inclusion and exclusion criteria.less blinding employment,unclear withdrawals and dropouts,and improper sample size.Conclusion The design and quality control of Chinese clinical nutrition RCTs still have some problems and require further improvement.

We reviewed the role of COX-2 independent targets of celecoxib and related compounds in cancer prevention and treatment. Direct non-COX-2 targets of celecoxib might be protein-dependent kinase 1 (PDK-1),Ca+ ATPase and carbonic anhydrase (CA), and so on; all of which are inhibited by celecoxib and are the main components in various pathways. Inhibition of these proteins leads to the induction of apoptnsis, the inhibition of cell cycle progression, angiogenesis, and metastasis, which are the main mechanisms by which celecoxib exerts its anticarcinogenic activity.

The new,rapid,accurate and convenient tests for tuberculosis diagnosis and drug resistance are urgently needed for effective tuberculosis control.In this review,two novel,inexpensive diagnosis methods of active TB were introduced.They can detect tuberculosis disease and drug resistances directly form sputum specimens and might have greater applicability in developing countries.Several concerns about the research and development of innovative diagnosis technology in our country also are described.
