Previous studies have indicated that adventitial inflammation is involved in the development of atherosclerosis. The aim of this study was to investigate the effect of arterial adventitia inflammation induced by interleukin (IL)1 on intimal proliferation and the mechanisms involved in this process. The left common carotid artery adventitia of male rats in the experimental and control groups (25 rats/group) was wrapped with agar containing or without a sustainedrelease suspension of 2.5 g IL1, respectively. Five animals in each group were randomly selected for sacrifice at 2 h, 8 h, 24 h, 48 h, and 1 week posttreatment. Hematoxylin and eosin staining was performed for to analyze the morphology of the adventitia. The expression of janus kinase (JAK)2, signal transducer and activator of transcription (STAT)3, phosphorylated (p)JAK2 and pSTAT3 were detected by western blot analysis or immunohistochemistry staining. A model of adventitial inflammation was successfully created by wrapping IL1 around the rat carotid artery. IL1 treatment induced vascular smooth muscle cell proliferation and migration as well as intimal proliferation. In addition, the expression of pJAK2 and pSTAT3 increased after IL1 treatment. Furthermore, an inhibitor of JAK2/STAT3 pathway, AG490, suppressed IL1induced intimal proliferation and phosphorylation of JAK2 and STAT3. Thus, the JAK2/STAT3 signaling pathway is involved in intimal proliferation caused by vascular adventitial inflammation. Inhibiting the JAK2/STAT3 signaling pathway may be a novel method for the clinical treatment of artery atherosclerosis.

Background:In recent years, a number of randomized controlled trials (RCTs) have reported on lenalidomide as a treatment for multiple myeloma (MM). Herein, we report results of a meta-analysis of RCTs examining the efficacy and safety of lenalidomide for MM.Patients and Methods:Databases were searched using the terms "lenalidomide or revlimid AND multiple myeloma."RCTs evaluating initial or maintenance therapeutic outcomes were included. Main outcome measures were response rates, progression-free survival (PFS), overall survival, and adverse events.Results:Seven trials were included (N = 192-614 participants). Lenalidomide doses and treatment regimens differed between trials. Complete response (CR) and very good partial response (VGPR) risk ratios (RR) favored lenalidomide over placebo (CR = 2.54, 95% confidence interval [CI] = 1.29-5.02; VGPR = 2.82, 95% CI = 1.30-6.09). The PFS hazard ratio favored lenalidomide over placebo (0.37, 95% CI = 0.33-0.41). For adverse events, neutropenia, deep vein thrombosis (DVT), infection, and hematologic cancer RR favored placebo over lenalidomide (neutropenia: 4.74, 95% CI = 2.96-7.57; DVT: 2.52; 95% CI: 1.60-3.98; infection: 1.98; 95% CI: 1.50-2.62; hematologic cancer: 3.20; 95% CI: 1.28-7.98).Conclusions:Lenalidomide is an effective treatment for MM; however, treatment-related adverse events must be considered and appropriate adjustments and/or prophylactic treatment should be initiated where possible. © 2013 Yang et al.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous family of myeloid cells that suppress T cell immunity in tumor-bearing hosts. In patients with colon cancer, MDSCs have recently been described as Lin-/lowHLA-DR-CD11b+CD33+ cells correlating with cancer stage, metastasis and chemotherapy response. To learn in more detail the dynamic change and clinical relevance of circulating and tumor-infiltrating Lin-/lowHLA-DR-CD11b+CD33+ MDSC in colorectal cancer, we harvested the blood from 64 patients with varying stage of colorectal cancer and tumor and matched paraneoplastic tissues from 5 patients with advanced colorectal cancer, subjected them to multicolor flow cytometric analysis of percentage, absolute number and phenotype of MDSC and finally characterized their immunosuppressive functions. Our results demonstrate that peripheral blood from colorectal cancer patients contains markedly increased percentage and absolute number of Lin-/lowHLA-DR-CD11b+CD33+ MDSCs compared with healthy individuals, and this increase is closely correlated with clinical cancer stage and tumor metastasis but not primary tumor size and serum concentrations of cancer biomarker. A similar increase of MDSCs was also observed in the tumor tissues. Phenotyping MDSCs shows that they express high CD13 and CD39, low CD115, CD117, CD124 and PD-L1, and devoid of CD14, CD15 and CD66b, reminiscent of precursor myeloid cells. MDSCs from cancer patients but not healthy donors have the immunosuppressive activity and were able to inhibit in vitro autologous T-cell proliferation. Collectively, this study substantiates the presence of increased immunosuppressive circulating and tumor-resident Lin-/lowHLA-DR-CD11b+CD33+ MDSCs in patients with colorectal cancers correlating with cancer stage and metastasis, and suggests that pharmacologic blockade of MDSCs should be considered in future clinical trials. © 2013 Zhang et al.

The understanding of rectoanal inhibitory reflex (RAIR) is progressing for the latest 100 years. From the discovery of its important role in diagnosis of Hirschsprung's disease to all aspects of its development, reflex pathways, neural regulation and physiological functions, there have been more in-depth explorations. It is now recognized that a number of other diseases also have a more specific performance of RAIR. It has become an important and indispensable part to anorectal manometry. Research progress of rectoanal inhibitory reflex is reviewed in this article.

This study was aimed to detect the expression of B7-H1 gene in the acute myeloid leukemia (AML) cells and to explore its clinical significance. The B7-H1 gene expression was detected by real-time quantitative PCR in bone marrow mononuclear cells (BMMNC) from 40 newly diagnosed AML patients, 10 normal volunteers and 10 relapsed patients. The results showed that the expression of B7-H1 from de novo AML patients was lower than that from the normal volunteers, but it was higher in the relapsed patients. The expression level of B7-H1 gene before therapy was significantly higher in non CR patients than that in CR patients after therapy. It is concluded that there is a correlation between the expression level of B7-H1 gene and response to therapy.

This study was aimed to investigate the effect of recombinant human granulocyte colony-stimulating factor(G-CSF) on murine thymocyte emigration and cell cycle alteration after a sublethal dose of gamma-irradiation. Female BALB/c mice were given 6.0 Gy γ-ray total body irradiation and then randomly divided into G-CSF and control groups. Mice in the G-CSF group were injected recombinant human G-CSF 100 μg/(kg·d) subcutaneously once daily for 14 consecutive days and mice in the control group were given the same volume of phosphate buffered solution. Thymocyte cycle alteration and the proportion of apoptosis cells were detected by flow cytometry within 72 hours after irradiation. Real-time PCR was used for detection and quantitation of murine T cell receptor rearrangement excision circles (sjTREC) of the thymic cells at 30 and 60 day after the irradiation. The results showed that at 6 hour after irradiation G-CSF could significantly increase the thymic cells in G(0)/G(1) phase, G-CSF vs control: (82.0 ± 5.0)% vs (75.9 ± 2.8)% (p < 0.05), and decrease the thymic cells in S phase, G-CSF vs control: (10.2 ± 4.8)% vs (15.7 ± 2.3)% (p < 0.05), but G-CSF seemed have no evident effects on the percentage of thymic cells in G(2)/M phase. G-CSF could also protect thymocytes from apoptosis at 6 hour and 12 hour after irradiation the percentages of apoptosis cells in G-CSF group were (11.5 ± 2.4)% and (15.5 ± 3.3)%, respectively, which were significantly lower than that of the control group (16.5 ± 2.2)% and (22.6 ± 0.7)%, respectively (p < 0.05). The sjTREC copy amount was conspicuously higher in G-CSF group than that in the control at 30 day after irradiation (p < 0.01), but the preponderance disappeared 60 days later. It is concluded that G-CSF has a positive effect on the thymic cell cycle alteration to protect thymocytes from apoptosis and enhance the recent thymocyte emigration, which may contribute to the central immune reconstitution after irradiation.

Result: A total of 18 studies were included in this meta-analysis, with a total of 762 subjects. Pooled sensitivity and specificity of PET and PET/CT were 0.91 (95 % CI 0.87–0.94) and 0.94 (95 % CI 0.89–0.97), and 0.92 (95 % CI 0.91–0.94) and 0.84 (95 % CI 0.74–0.91), respectively. The areas under the SROC curve (AUCs) of PET and PET/CT were 0.9610 and 0.9491, respectively. There was no statistical significance between the AUC of PET and PET/CT (P > 0.05).Conclusion: Both PET and PET/CT have good performance in the detection of recurrent cervical cancer. However, interpreted CT images may have limited additional value on PET in detecting recurrent cervical cancer.Objective: The aim of this work was to assess and compare the overall value of stand-alone FDG PET and PET/CT in diagnosing recurrent cervical cancer with a meta-analysis.Methods: All the English published studies which addressed the use of PET whether interpreted with or without the use of CT for the diagnosis of recurrent cervical cancer were collected. Methodological quality of the included studies was evaluated. Pooled sensitivity and specificity were calculated, summary receiver operating characteristics (SROC) curve analysis was used to compare the diagnostic ability of stand-alone PET and PET/CT. © 2014, Springer-Verlag Berlin Heidelberg.

The aim of the present study was to determine the effects of ulinastatin (UTI) on brain injury in rats subjected to cardiopulmonary resuscitation (CPR) following asphyxial cardiac arrest (CA) and identify the underlying mechanisms. In total, 100 healthy male Wistar rats were randomly divided into control and treatment groups (n=50). After 4 min of asphyxial CA, all the rats were immediately subjected to CPR. The treatment group animals were administered 15 mg/kg UTI at the onset of resuscitation. The mortality rate in the two groups was recorded at 24 h post-resuscitation. In addition, neurological function was evaluated at 24, 48 and 72 h post-resuscitation using a neurological deficit scale (NDS). Furthermore, the effects of UTI on the Toll-like receptor 4 (TLR4) signaling pathway in brain tissues were determined by assessing TLR4 mRNA expression, nuclear factor (NF)-κB activity and tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels at 1, 3, 6, 12, 24, 48 and 72 h post-resuscitation. After 24 h, the mortality rate significantly decreased in the treatment group when compared with the control animals (10 vs. 30%; P<0.05). Additionally, an overt improvement was observed in the NDS score following UTI treatment when compared with the control (P<0.01). Finally, statistically significant decreases in the levels of TLR4 mRNA expression, NF-κB activity and TNF-α and IL-6 were observed in the treatment group at each time point (P<0.01). Therefore, UTI treatment at the onset of CPR significantly inhibits the TLR4 signaling pathway, thereby alleviating the inflammatory responses following resuscitation and improving neurological function.

Adefovir dipivoxil is commonly used for treatment of chronic hepatitis B patients. We present a case of acquired Fanconi syndrome and hypophosphatemic osteomalacia in a patient with chronic hepatitis B who had been treated with ADV for 8years. A 41-year-old man complained of severe bilateral hypochondrium pain and lower limb weakness, and he had the diagnosis of bone metastasis cancer or multiple myeloma. Laboratory results and radiologic findings suggested Fanconi syndrome with osteomalacia after hospitalized. For it is difficult to accurately diagnose in clinic and prone to misdiagnose, more attention should be paid to the kidney damage in the patients treated with long-term ADV.
