RESUMO
Metastasis is the main factor leading to the death of patients with lung cancer, and active prevention is the key to improve the efficacy of treatment. Circulating tumor cells (CTCs) play an important role in initiating metastasis. They trigger a series of metastatic cascade reactions at the moment of shedding from the primary focus, and finally colonize and proliferate in the distant target organs. In recent years, the detection technology of lung cancer CTCs has been continuously optimized. It can not only count CTCs, but also identify different subsets. CTCs detection of lung cancer can be used for early screening, the prediction of prognosis after surgery and chemoradiotherapy and the evaluation of curative effect of targeted immunotherapy. Dynamic monitoring of tumor heterogeneity is helpful to adjust personalized treatment plan and achieve the accurate treatment of cancer. Tian Jianhui's research group established the world's first circulating tumor cell line of human lung adenocarcinoma, integrated it into the theory of "positive deficiency and toxin" in the subclinical core pathogenesis of lung cancer, and actively promoted the construction of a specific research platform for lung cancer, in order to improve the research, prevention and control efficiency of lung cancer metastasis.

RESUMO
Objective@#To explore the mechanisms of vascular endothelial growth factor receptor 2 (VEGFR2) expression regulated by recombinant human erythropoietin (rh-EPO) in a premature rat model of periventricular white matter damage. @*Methods@#Sprague-Dawley rats aged three days were randomly divided into five groups: sham group without hypoxia-ischemia (HI), HI group (HI with saline administration), HI+erythropoietin (EPO) group, HI+erythropoietin receptor (EPOR) antagonist group and HI+EPO+EPOR antagonist group. Rat pups were either subjected to permanent ligation of the right common carotid artery and 6% O2+94% N2 for two hours (HI) or sham operated and exposed to normal air (sham). After the operation, rats in the HI+EPOR antagonist and HI+EPO+EPOR antagonist groups received a single intraventricular injection of EPOR antagonist (5 μl). Four hours after the operation, rats in the HI+EPO and HI+EPO+EPOR antagonist groups received a single intraperitoneal injection of rh-EPO (5 U/g). Western-blot was performed to detect EPOR, phosphorylated EPOR (p-EPOR), extracellular regulated protein kinases (ERK) and phosphorylated ERK (p-ERK) at 60 and 90 minutes after the models were established successfully, and also used to analyze the expression of VECFR2 on day 2 and 4. Analysis of variance and SNK test were used as statistical methods. @*Results@#At 60 and 90 minutes after model establishment, the expression of EPOR protein in rat brain tissues was increased in HI (1.717±0.206 and 1.416±0.242), HI+EPO (2.557±0.222 and 2.111±0.159) and HI+EPO+EPOR antagonist (1.547±0.170 and 1.452±0.250) groups as compared with that in sham group (1.095±0.182 and 0.751±0.136), that in HI+EPO group was higher than that in HI and HI+EPO+EPOR antagonist groups, and that in HI+EPOR antagonist group (1.088±0.160 and 1.020±0.174) was lower than that in HI group. All differences were statistically significant (F=30.154 and 20.265, both P<0.05). The expressions of p-EPOR, p-ERK and VEGFR2 in the five groups were consistent with the expression of EPOR, and the differences were also statistically significant (all P<0.05). In addition, the expression of VEGFR2 in HI+EPO+EPOR antagonist group was lower than that in HI group on day 4 (1.053±0.118 vs 1.439±0.074, F=54.248, P<0.05). No statistically significant difference in ERK expression was found among all groups at 60 or 90 minutes after modeling (F=1.117 and 0.734, both P>0.05). @*Conclusions@#ERK signaling pathways will be affected by EPO binding to EPOR. As a result, VEGFR2 expression was increased leading to enhanced angiogenesis in a premature rat model of periventricular white matter damage.

RESUMO
ObjectiveTo determine the changes in tumor necrosis factor-α (TNF-α) and interleukin-lβ (IL-1β)expression after bone marrow mesenchymal stem cells (BMSCs) transplantation in a rat pup model of hypoxic-ischemic brain damage (HIBD) and discuss the anti-inflammatory mechanism of BMSCs transplantation in the repair of HIBD.MethodsThree-day-old Sprague-Dawley rat pups were randomly divided into three groups: the transplantation group, in which a model of HIBD was established by ligation of left common carotid artery and hypoxia for two hours followed by the injection of 2μl BMSCs (2×105 cells) into the lateral ventricle; the HIBD model group, in which HIBD model was established and 2μl phosphate saline buffer was injected into the lateral ventricle; and the sham-operation group, in which no intervention was given. Histological changes in the brain were detected by HE staining and the number of cells positive for ectodermal dysplasia-1 (ED-1) staining, which is a specific marker for activated microglia, was detected by immunohistochemistry. The protein and mRNA levels of TNF-α and IL-1β were determined by enzyme-linked immunosorbent assay and reverse transcription-polymerase chain reaction. One-way analysis of variance and LSD test were applied for statistical analysis.ResultsHE staining showed that cellular edema and necrocytosis was not observed in cerebral white matter on the 7th post-transplantation day in the transplantation group, but observed in the HIBD model group. In the sham-operation group, cerebral white matter was normal. The number of ED-1 positive cells in the transplantation group (26.3±2.5) was significantly lower than that in the HIBD model group (33.0±4.0), but higher than that in the sham-operation group (2.3±0.6) (LSD test, allP<0.05). The contents of TNF-α and IL-1β both in the transplantation group and the HIBD model group increased and peaked 24 h after transplantation, then gradually decreased, but did not reach normal levels (sham-operation group) on the 7th day. The contents of TNF-α and IL-1β in brain tissue in the HIBD model group [TNF-α: (3.03±0.10), (5.57±0.19), (7.78±0.19), (4.39±0.20), (2.70±019)μg/L; IL-1β:(293.1±7.9), (369.8±17.5), (303.6±23.9), (226.7±21.6), (183.9±33.4) ng/L] were significantly higher than those in the transplantation group [TNF-α: (2.84±0.20), (3.80±0.14), (4.63±0.17), (3.56±0.03), (1.99± 0.17)μg/L; IL-1β: (267.6±14.5), (323.5±26.9), (211.2±24.9), (140.8±7.4), (100.2±8.3) ng/L] at 6, 12, 24, 48 h and 7 days after BMSCs transplantation, respectively. The contents of TNF-α and IL-1β in the sham-operation group [TNF-α:(1.03±0.02), (1.13±0.03), (1.05±0.02), (1.09±0.02), (1.07±0.02)μg/L; IL-1β:(63.6±13.0), (64.0±11.3), (60.8±10.0), (67.9±13.5), (66.2±11.7) ng/L] were significantly lower than those in the transplantation group and HIBD model group (LSD test, allP<0.05). TNF-α and IL-1β mRNA at 24 h after transplantation in the HIBD model group (TNF-α: 2.69±0.43; IL-1β: 3.07±0.38) were significantly higher than those in the transplantation group (TNF-α: 1.61±0.29; IL-1β: 1.08±0.11) and those in the sham-operation group (TNF-α: 0.94±0.16; IL-1β: 1.08±0.11) (LSD test, allP<0.05).ConclusionsBMSCs may play an important role in the recovery of preterm HIBD and the mechanism may involve the inhibition of microglia activation and down-regulation of the expression of inflammatory factors.
RESUMO
Objective To investigate the clinical value of neutrophil-to-lymphocyte ratio,platelet-to-lymphocyte ratio and red blood cell distribution width in discriminating disease activity of rheumatoid athritis.Methods Eighty-nine rheumatoid arthritis out-patients of the Affiliated Hospital of Jiangsu University from Jan.2012 to Mar.2013 were recruited into this study.The disease activity index,such as swollen joint count and tender joint count were made by rheumatologists,and laboratory parameters（blood cell analysis,erythrocyte sedimentation rate and C-reactive protein) were measured as well.The enrolled patients were divided into the active RA group and remission RA group based on the DAS28 definition.Differences of NLR,PLR and RDW among groups were analyzed by t test and relations between variables were assessed by Spearman correlation analysis.The t test,non-parametric test and Spearman analysis were used for statistical analysis.Results The levels of NLR (3.2±2.0,2.4±0.9,respectively) and PLR (167±70,133±43,respectively) in active RA group were higher than that of the RA remission group (t=2.28 and 2.50,P=0.02 and 0.01).The level of RDW [(13.9±2.5)％,(13.9±2.4)％,respectively] was not significantly different between the active RA group and the RA remission group (t=0.14,P=0.89).However,compared with healthy controls,the level of RDW [(13.9±2.5)％,(13.2±0.2)％,respectively] was significantly increased in RA patients (t=2.74,P=0.006 9).NLR and PLR were positively correlated with DAS28 (r=0.23,P=0.03;r=0.26,P=0.04,respectively),ESR (r=0.28,P=0.03;r=0.43,P＜0.01,respectively) and CRP (r=0.33,P=0.006;r=0.41,P＜0.01,respectively).However,there was no association between RDW and DAS28 (r=0.01,P=0.93),ESR (r=0.20,P=0.15) and CRP (r=0.05,P=0.71).Areas under curve of receiver operating characteristic (ROC) for assessing disease activity of rheumatoid athritis by NLR and PLR were 0.802 and 0.753 respectively.The cut-off values for discriminating active/remission RA were 2.86 and 143.05,with the sensitivity as 0.66 and 0.63,specificity as 0.72 and 0.65.Conclusion NLR and PLR are significantly associated with the disease activity of RA and can be useful to understand the activity state of the illness.

Data of both groups were significantly lower than before treatment,(t =5.234 vs.4.267,4.627 vs.3.532,4.872vs.3.726,5.021 vs.3.429,6.046 vs.3.848,10.477 vs.6.818,11.557 vs.6.686,9.267 vs.6.421,12.712 vs. 5.044,all P <0.05).The ADL score were (28.7 ±11.2)point vs.(22.5 ±10.1)point,and the data of both groups were significantly higher than before treatment (t =8.396 vs.5.336,all P <0.05).The high shear whole blood vis-cosity,erythrocyte aggregation index,hematocrit,fibrinogen,erythrocyte sedimentation rate,endothelin,CRP,IL -1 and NHISS of the observation group were significantly lower than the control group(t =3.207,3.388,3.667,3.761, 3.959,3.929,3.884,3.304,3.778,all P <0.05).The ADL score of the observation group were significantly higher than the control group(t =3,447,P <0.05);The total effective rate of the observation group and control group were 95.35% (41 /43 )vs 69.77% (30 /43 ),the difference was statistically significant (χ2 =10.904,P <0.05 ). Conclusion The method contained atorvastatin and urinary kallidinogenase have exact clinical efficacy,can improve neurological deficit assessment and the ability of daily life.Its mechanism may be that it can reduce endothelin levels of inflammatory mediators and improve blood circulation,which is worthy of clinical use.
RESUMO
Objective To understand the awareness rate of macrosomia related knowledge and influencing factors among pregnant women in Zhejiang province and provide evidence for the improvement of pre-gestational and prenatal care. Methods A face to face questionnaire survey was conducted among 1 512 pregnant women selected through multistage cluster random sampling from 20 counties(district)in Zhejiang. Macrosomia-related knowbedge awareness and related factors were analyzed. Results A total of 1 494 valid questionnaires were analyzed,the awareness rate was 40.7%for macrosomia diagnostic criteria(95%CI:38.2%-43.2%),55.0%for the cause of macrosomia(95%CI:52.4%-57.6%) and 62.4% for prevention related knowledge(95%CI:59.9%-64.9%) and the awareness rate of both the cause and the prevention related knowledge was 49.0%(95%CI:46.4%-51.6%). Multivariate logistic regression analysis showed that the third trimester of pregnancy(OR=1.906,95%CI:1.128-3.221),urban residence(OR=1.335,95%CI:1.014-1.756),educational level of junior college(OR=2.474,95%CI:1.635-3.744)and educational level of regular college or above (OR=2.072,95%CI:1.338-3.209),receiving health education about health pregnancy(OR=1.936, 95%CI:1.509-2.484)and self-learning about the knowledge of health pregnancy(OR=2.065,95%CI:1.338-3.189)were the influencing factors to the awareness rate of macrosomia diagnostic criteria and prevention related knowledge of macrosomia among pregnant women. The awareness rate of the cause and prevention related knowledge of macrosomia was higher in older age group(OR=2.103,95%CI:1.330-3.323). Conclusion Among the pregnant women in Zhejiang,the awareness rate of macrosomia diagnostic criteria was less than 50%. Therefore,it was necessary to strengthen the health education during pre-gestational and gestational periods among reproductive women,especially the education about pregnancy health in rural area.

RESUMO
Objective To study the effects and preliminary mechanism of Stattic (Y705),an inhibitor of the signal transducer and activator of transcription-3 (STAT3),on the growth,migration,invasion and radiosensitization of hepatocellular carcinoma cell line Bel-7402.Methods Bel-7402 cells were divided to four groups:blank control group,Stattic treatment group,radiation group,and Stattic combined with radiation group.The cell growth and proliferation were detected by using CCK8 kit.The influence of Stattic on radiation sensitivity of Bel-7402 cells was determined by clone formation assay.The cell migration and invasion ability were tested by scratch migration assay and transwell assay,respectively.The protein expressions of STAT3,p-STAT3,Bax,Bcl-2,Caspase-3,Cleaved Caspase-3,MMP-2 and MMP-9 were quantified by Western blotting assay.Results Stattic significantly inhibited the growth of human hepatocellular carcinoma Bel-7402 cells with a dose-depended manner.The IC50 of Stattic after 48 h treatment was 2.5 μ mol/L.When 1.0 μmol/L Stattic was combined with 8 Gy X-rays,there was a synergistic effect in inhibition of cell proliferation with a inhibition rate of (15.00 ± 1.87) ％ (F =63.30,P ＜ 0.05).Scratch migration assay and transwell invasion assay showed that the migration and invasion abilities of the combination group were significantly reduced.In addition,compared with the radiation group,the SF2,D0and Dq values obtained from survival curve were decreased (t =4.20,6.92,9.32,P ＜0.05),the protein expressions of p-STAT3,MMP-2,MMP-9 were reduced (t =5.32,6.02,13.26,P ＜0.05),the protein expressions of Bax and Cleaved Caspase-3 were increased in the combination group(t =-7.82,-14.09,P ＜ 0.05),meanwhile the protein expressions of Bcl-2 was decreased (t =18.43,P ＜ 0.05).When the concentration of Stattic was 0.5 μmol/L,the radiation sensitization ratio at 2 Gy (SERSF2) was 1.22.Conclusions By inhibiting the activation of the p-STAT3 in Bel-7402 cells,stattic could induce cell apoptosis and increase the radiosensitivity,down regulate MMP-2 and MMP-9 and thereby reduce the invasion and migration of tumor cells.
RESUMO
OBJECTIVE@#To observe the therapeutic effect of radiotherapy combined with TPF in patients with nasopharyngeal carcinoma (NPC) and to explore the influencing factors on prognosis of NPC.@*METHOD@#A retrospective analysis of 144 patients with nasopharyngeal carcinoma receiving radiotherapy combined with chemotherapy, from January 2006 to December 2011, was conducted. The survival analysis in patients with nasopharyngeal carcinoma were performed. The impact of age, sex, clinical stage, alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), lactate dehydrogenase (LDH), homocysteine (Hcy), uric acid, NK cell proportion, T cell proportion, Carbohydrate antigen on survival time was observed with univariate and multivariate methods.@*RESULT@#By the last follow-up, 9 cases were lost . The follow-up rate was 93.75 percent and the average follow-up time were 54.67 ±17.17 (37-88) months. The age, clinical stage, LDH, proportion of T cells and NK cells were independent factor in patients with NPC with univariate analysis (P < 0.01). COX regression multivariate analysis revealed that age, clinical stage and LDH were strong risk factor affecting prognosis (P < 0.01) and the proportion of NK cells and T cells were protective factors (P < 0.01).@*CONCLUSION@#Radiotherapy combined with TPF is more effective than radiotherapy alone in patients with nasopharyngeal carcinoma . Age, clinical stage and LDH may adversely influence the disease prognosis, and NK cells and T cell proportion may act as protective factors.
