Over the past years, the incidence of lymphoma has been increasing, which has become one of the most common cancers around the world.The survival of lymphoma patients has been significantly improved due to advances of therapeutic methods such as new chemotherapy regimens, monoclonal antibodies and small molecular targeted drugs.However, the number of patients with relapsed/refractory lymphoma still account for a large proportion.It is of great significance to find new ways to treat these patients.Cellular immunotherapy could kill tumor cells by causing specific and effective antitumor immune response.Remarkable advances have been made in immunotherapy, such as adoptive immunotherapy, immune checkpoint inhibitors and immunomodulation therapy, for relapsed/refractory lymphoma patients, which will gradually open a new era in the treatment of lymphoma.

Adenosine receptors (AR) play an important role in the regulation processes for body temperature and vigilance states. During our previous studies, we noticed that aminophylline (a non-selective, blood-brain-barrier penetrably AR antagonist) could attenuate the effects of YZG-330 [(2R,3S,4R,5R)-2-(hydroxymethyl-5-(6-(((R)-1-phenylpropyl)amino)-9H-purin-9-yl)tetrahydrofuran-3, 4-diol] on lowering the body temperature. Hereby, we focused ourselves on the character of thermal regulation effect of YZG-330 in mice and tried to specify the receptor subtype via giving typical adenosine receptor antagonists. The results showed that both of the magnitude and lasting time of the effect that YZG-330 played on decreasing body temperature are in a dose-dependent manner: within the next 3 hour after intragastric administration (ig) of 0.25, 1 or 4 mg . kg-1 YZG-330, the extreme values on body temperature decreasing were (1.2 ± 0.3) °C, (3.6 ± 0.4) °C (P<0.001) and (7.4±0.5) °C (P<0.001), separately; whereas the duration that body temperature below 34 °C were 0, (10±5) and (153±4) min, separately. Adenosine A1 receptor (A1R) antagonist (DPCPX) could effectively reverse YZG-330's effect on decreasing body temperature, with intraperitoneal administration of DPCPX (5 mg . kg-1) 20 min prior than YZG-330 (4 mg.kg-1, ig), the extreme value on body temperature decreasing was (3.5 ± 0.7) °C (P<0.001), the duration that body temperature below 34 °C was (8±6) min (P<0.001). However, adenosine A2a receptor antagonist, SCH-58261, did not show any influence on the effects of YZG-330 at all. Combined with the fact that 8-SPT (a non-selective, blood-brain-barrier impenetrably AR antagonist) did not reverse the effect of YZG-330, we come to the conclusion that central-adenosine A, receptor plays a significant role on the thermal regulation effect of YZG-330.

Background Retinal development continues during the early postnatal period in mammals.Correct arrangement of layers and precise location of various cells in the retina are vital for forming normal visual function during critical period plasticity.Spectral-domain optical coherence tomography(SD-OCT)provides highquality in vivo retinal imaging and the possibility to measure retinal thickness longitudinally. Objective The present study was to investigate the changes of retinal thickness during critical period plasticity in rats. Methods In vivo consecutive scanning of retinal image was performed in 10 SPF Sprague-Dawley rats at postnatal day 14(P14),P18,P21,P24 and P42 with SD-OCT,and retinal histopathological examination was used to detect retinal morphologic changes at the same postnatal ages in 20 matched rats.The whole retinal thickness,the thickness from inner limiting membrane(ILM)to inner plexiform layer(IPL),the thickness of inner nuclear layer(INL)and the thickness from outer nuclear layer(ONL)to retinal pigment epithelium(RPE)were measured using Cirrus HD-OCT system and HMIAS-2000 Imaging System in retinal sections.The measurement parameters by Cirrus HD-OCT and those by hematoxylin-eosin staining were compared.The use of animals followed the Statement of National Institute of Health (USA). Results In vivo high-resolution images of rat retinas with SD-OCT compared well with histology,which enabled quantitative comparison of the SD-OCT and histological data during critical period plasticity in rats.From P14 to P42,the retinal thickness gradually decreased with the increase of rat ages(F=15.425,P=0.000),and so were the thickness from ILM to IPL,the thickness of INL and the thickness from ONL to RPE(F=3.973,P=0.007;F=17.529,P=0.000;F=7.038,P=0.000).The retinal thickness,thickness of INL.thickness from ONL to RPE measured by Cirrus HD-OCT were significantly correlated with those measured by retinal sections among P14,P18,P21,P24 and P42 rats(r=0.794,P=0.000;r=0.784,P=0.000;r=0.681,P=0.000). Conclusion SD-OCT is a demonstratably valuable technology to study the structure of retinas in rats.The retinal thickness is shown to reduce in thickness throughout the development of the retina during critical period plasticity due to the decrease in thickness of INL and the distance from the ONL to RPE,as illustrated by OCT scanning.

OBJECTIVETo evaluate the efficacy and safety of testosterone undecanoate (TU) in the treatment of late-onset hypogonadism (LOH) by meta-analysis.

METHODSWe searched Pubmed (until April 1, 2014), Embase (until March 28, 2014), Cochrane Library (until April 17, 2014), CBM (from January 1, 2001 to February 2, 2014), CNKI (from January 1, 2001 to February 2, 2014), Wanfang Database (from January 1, 2000 to February 2, 2014), and VIP Database (from January 1, 2000 to Febru ary 2, 2014) for randomized controlled trials of TU for the treatment of LOH. We evaluated the quality of the identified literature and performed meta-analysis on the included studies using the Rveman5. 2 software.

RESULTSTotally, 14 studies were included after screening, which involved 1 686 cases. Compared with the placebo and blank control groups, TU treatment significantly increased the levels of serum total testosterone (SMD = 6.22, 95% CI 3.99 to 8.45, P < 0.05) and serum free testosterone (SMD = 4.35, 95% CI 1.86 to 6. 85, P < 0.05) but decreased the contents of luteinizing hormone (WMD = -2.23, 95% CI -4.03 to -0.42, P < 0.05), sex hormone binding globulin (WMD = 2.00, 95% CI 1.38 to 2.63, P < 0.05). TU also remarkably reduced the scores of Partial Androgen Deficiency of the Aging Males (WMD = -9.49, 95% CI -12.96 to -6.03, P < 0.05) and Aging Males Symptoms rating scale (WMD = -2.76, 95% CI -4.85 to -0.66, P <0.05) but increased the hemoglobin level (SMD = 2.35, 95% CI 0.29 to 4.41, P < 0.05) and packed-cell volume (SMD = 4.35, 95% CI 1.36 to 7.33, P < 0.05). However, no significant changes were shown in aspertate aminotransferase, alanine transaminase, prostate-specific antigen, or prostate volume after TU treatment (P > 0.05).

CONCLUSIONTU could significantly increase the serum testosterone level and improve the clinical symptoms of LOH patients without inducing serious adverse reactions. However, due to the limited number and relatively low quality of the included studies, the above conclusion could be cautiously applied to clinical practice.

Conclusions Short-term efficacy demonstrates that intra-tissue radiotherapy of ~(125)I had significant efficacy for advanced tumors.

Objectives To investigate the ameliorative effect of cannabinoid 2 receptor(CB2R)agonist JWH-015 on the cog-nitive impairment of Alzheimer' s disease(AD)model mice and to assess the correlation with microglial phenotype transformation. Methods Twenty adult male C57BL/6J mice were randomly divided into four groups:C57BL/6J solvent group,JWH-015 control group,AD model group,and AD model treated with JWH-015 group. Amyloidβ1-42 oligomers of 4μg and the same volume of saline were intraventricularly administered to construct the AD mouse model and the solvent groups. CB2R agonist JWH-015 or the corre-sponding vehicle at a dose of 0.5 mg/(kg·d)was administered by intraperitoneal injection for 3 weeks. Non-spatial learning and memo-ry was measured using novel object recognition task. Furthermore,the mRNA expression levels of M1 microglia marker inducible ni-tric oxide synthase(iNOS)and M2 microglia marker chitinase-3 like protein(Ym1/2)in brain samples of cortex and hippocampus were evaluated using real-time quantitative PCR(qPCR). In the meantime,fifteen CB2R knockout(CB2RKO)mice and five CB2R wild-type(CB2RWT)littermates were assigned to identify the specificity of CB2R in the research. Based on the genotype and different treatment,the animals were divided into four groups:CB2RKO solvent group,CB2RKO AD model group,CB2RKO AD model treat-ed with JWH-015 group and CB2RWT solvent group. Results Compared with solvent group,there was a significant decrease in nov-el object recognition index in C57BL/6J AD model group(P<0.01). The mRNA expression levels of M1 phenotype microglia marker iNOS in cortex and hippocampus were significantly up-regulated(both P<0.05)and the mRNA expression levels of M2 phenotype mi-croglia marker Ym1/2 were significantly down-regulated(both P<0.01). Interestingly,administration of JWH-015 could reverse the impairment of novel object recognition index(P<0.05);compared with C57BL/6J AD model group,administration of JWH-015 also decreased the iNOS mRNA expression levels(both P<0.05)and increased the Ym1/2 mRNA expression levels(both P<0.05)in cortex and hippocampus;compared with CB2RKO solvent group,the novel object recognition index of CB2RKO AD model group was decreased(P<0.05);the mRNA expression levels of iNOS in cortex and hippocampus were significantly up-regulated(both P<0.05),the mRNA expression level of Ym1/2 in cortex was significantly down-regulated in cortex(P<0.05);compared with CB2RKO AD model group,administration of JWH-015 had no effect on novel object recognition index and the mRNA expression level of M1/M2 in cortex and hippocampus,respectively. Conclusion JWH-015 improves the cognitive impairment of Aβ-induced AD mice by the specific activation of CB2R,the mechanism of which is related to the direct regulation of CB2R on the M1/M2 microglial phenotype transformation and microglia-mediated neuroinflammation in brain.

Hypoxic-ischemic brain damage (HIBD) is referred to a common type of cerebral damage, which is caused by injury, leading to shallow bleeding in the cortex with intact cerebral pia mater. In recent years, studies show that a various kinds of immune cells and immune cellular factors are involved in the occurrence of HIBD. CC chemokine receptor 2 (CCR2) is a representative of CC chemokine receptor, and is widely distributed in cerebral neuron, astrocyte, and microglial cells, and is the main chemo-tactic factor receptor in brain tissue. CC chemokine ligand 2 (CCL2) is a kind of basophilic protein and the ligand of CCR2, and plays an important role in inflammation. In order to provide evidence for correlational studies in HIBD, this review will introduce the biological characteristics of CCR2 and CCL2, and illustrate the relationship between the immunoreactivity and HIBD.
