Objective To investigate the expression and significance of IL-6 and IL-6 receptor (IL-6R)in hysteromyoma.Methods The expression of IL-6 in hysteromyoma and homologous normal myometrium of 20 cases undergoing total hysterectomy were detected by fluorescent quantitative PCR and western-blot,respectively while IL6R was examined by western-blot and RT-PCR.Results The expression of IL-6 protein and mRNA in homologous normal myometrium were obviously higher than that in hysteromyoma[(0.7996 ±0.0359)vs (0.6904 ±0.0414)and (0.0470±0.0071)vs(0.0283±0.0045 ),P＜0.05] ;No difference was observed in IL-6R protein and mRNA expression between leiomyomas and myometrium[(0.7105 ±0.0520)vs (0.6904 ±0.0532)and (0.6644 ±0.0537 )vs (0.6465±0.0501),P＞0.05 ].Conclusion The lower expression of IL-6 in leiomyomas may contribute to the pathogenesis of hysteromyoma to some extent,and there is no relationship between IL-6R and hysteromyoma.

Clinical data of 23 patients with T2a bladder cancer admitted from March 2008 to August 2013 were retrospectively analyzed.Among 23 patients,11 cases were treated with transurethral resection (TURBT) plus arterial catheterization chemotherapy (study group) and 12 cases were treated with radical cystectomy (control group).The overall survival time and recurrence free survival time of two groups were compared.Patients in study group were followed up for 20-68 months,recurrence occurred in 5 cases (5/11),including 4 cases of invasive recurrence;patients in control group were followed up for 2 ～86 months,1 case had superficial recurrent and underwent TURBT,2 cases dead due to bladder tumor.During the course of chemotherapy,the main adverse effects were digestive reaction (7/11),fever (4/11),bone marrow suppression (2/11),symptomatic treatment was given,which was tolerated.There were no significant differences in overall survival time and recurrence free survival time between two groups (P ＞ 0.05).The quality of life of study group was better than that of control group (P ＜ 0.05).It is suggested that the arterial interventional chemotherapy combined with transurethral resection for T2a stage invasive bladder cancer has a certain curative effect with the advantage of preservation of bladder function and higher quality of life.

Objective To investigate the effects of low molecular heparin(LWMH)on cytokines(TNF-?,IL-1? and IL-10)in blood plasma and bronchoalveolar lavage fluid of invasive pulmonary aspergillosis(IPA)mice.Methods The neutropenic IPA mouse models were established by administration of cyclophosphamide for immunologic function inhibition and intranasally challenge with Aspergillus fumigatus conidia(1?106 conidia/mouse).One hundred and twenty mice were randomly divided into 4 groups:normal control,IPA model,normal saline+LWMH and IPA+LWMH group.Normal saline+LWMH group and IPA+LWMH group received LWMH(subcutaneous injection,1 000 IU/kg,qd?2 d).Normal control and IPA model group received normal saline instedad of LWMH.At 4,8,12,24 and 48 h after inoculation,six mice were randomly taken from each group to be sacrificed.ELISA method was used to determine the concentrations of TNF-?,IL-1? and IL-10 in blood plasma and BALF.Results TNF-?,IL-1? and IL-10 in blood plasma and BALF increased significantly several hours after inoculation of conidia in IPA model and IPA+LWMH group.There were significant higher concentrations of TNF-? and IL-1? in blood plasma and BALF in IPA+LWMH group than in IPA model group(P

Objective:To observe the efficacy of cytokine-induced killer (CIK) cells on patients with advanced lung cancer. Methods:A total of 90 patients with advanced lung cancer were identified from January 2011 to December 2013. CIK therapy was given to 41 pa-tients in the observation group, whereas the other 49 patients in the control group received the best support treatments without che-motherapy or radiotherapy within one month of inclusion. Following up was conducted for the patients in the two groups, and KPS scores, median survival, and adverse reactions compared. Results:The KPS score in the observation group was higher than that of the control group after treatment (P=0.034). The median survival period of the observation group was eight months, which was one month longer than that of the control group (P=0.044). Major adverse reactions included fever, joint pain, and insomnia, which were recorded 51.22%, 36.58%, and 29.27%of occurrence, respectively. Conclusion:CIK cell therapy improved the quality of life and pro-longed the survival of advanced lung cancer patients with tolerable adverse reactions.

Neurons in the laterodorsal tegmentum (LDTg) and pedunculopontine tegmental nucleus (PPTg) play important roles in central autonomic circuits of the kidney. In this study, we used a combination of retrograde tracers pseudorabies virus (PRV)-614 and fluorescence immunohistochemistry to characterize the neuroanatomic substrate of PPTg and LDTg innervating the kidney in the mouse. PRV-614-infected neurons were retrogradely labeled in the rostral and middle parts of LDTg, and the middle and caudal parts of PPTg after tracer injection in the kidney. PRV-614/TPH double-labeled neurons were mainly localized in the rostral of LDTg, whereas PRV-614/TH neurons were scattered within the three parts of LDTg. PRV-614/TPH and PRV-614/TH neurons were located predominantly in the caudal of PPTg (cPPTg). These data provided direct neuroanatomical foundation for the identification of serotonergic and catecholaminergic projections from the mid-brain tegmentum to the kidney.

OBJECTIVETo study the mechanism underlying the inhibitory effect of Qingluo Tongbi Granule (, QTG) on osteoclast differentiation in rheumatoid arthritis in rats.

METHODSFibroblast and monocyte co-culture were used to induce osteoclast differentiation in adjuvant-induced arthritic (AIA) rats. Serum containing QTG was prepared and added to the osteoclasts, and activation of the tumor necrosis factor receptor-associated factor 6/mitogen-activated protein kinase/nuclear factor of activated T cells, cytoplasmic1 (TRAF6/MAPK/NFATc1) pathways was examined.

RESULTSThe induced osteoclasts were multinucleated and stained positive for tartrate-resistant acid phosphatase (TRAP) staining. Serum containing QTG at 14.4, 7.2 or 3.6 g/kg inhibited the activation of TRAF6, extracellular regulated protein kinase (ERK)1/2, c-Jun N-terminal kinase (JNK) and p38 and decreased the percentage of cells with nuclear NFATc1 in a dose-dependent manner, the high and middle doses exhibited clear inhibitory activity (P<0.01 and P<0.05, respectively). After the addition of MAPK inhibitors, the NFATc1 expression showed no significant difference compared with the control group (P>0.05).

CONCLUSIONSSerum containing QTG could generally inhibit the TRAF6/MAPK pathways and possibly inhibit the NFATc1 pathway. In addition, QTG may regulate other signaling pathways that are related to osteoclast differentiation and maturation.

OBJECTIVETo investigate the exact mechanism of SARS-CoV pathogenesis at the protein level.

METHODUnder the condition of the establishment of dendrtic cells (DC) culture method, we used recombinant adenovirus to infect mature DC to make clear the development changes in mRNA levels and secreted protein levels of proinflammatory cytokines of IL-1beta, IL-6, IL-8 and TNF-alpha by using RT-PCR and ELISA.

RESULTWe found that mRNA levels and secreted protein levels of IL-6 and TNF-alpha in DC had increased gradually after rAd-N infection during first 24 h compared with the control DC infected by rAd-LacZ (P < 0.05 or P < 0.01).

CONCLUSIONIt is suggested that N protein may be related to the excessive secretion of proinflammatory cytokines during SARS-CoV infection at the acute phase.
