To assess the clinical effect and safety of Chinese traditional medicine injection combined with radiotherapy for esophageal cancer. The relative randomized controlled trials (RCTs) of Chinese medical injections (CMI) combined with radiotherapy as well as simple radiotherapy for esophageal cancer were searched from PubMed, Cochrane Library, EMBASE, Chinese Biomedical Literature Database(CBM), China National Knowledge Infrastructure (CNKI), Wanfang Database and VIP Database as at September 2014. Two researchers completed the data extraction and quality evaluation independently. The data were analyzed by GeMTC 0.14.3 and Stata 12. 0 software. Finally, 43 RCTs involving 3 289 patients were finally included. The star network was constructed by different comparison groups. The results of network meta-analysis showed that the seven CMIs combined with radiotherapy was superior to simple radiotherapy in the treatment of esophageal cancer in efficacy, quality of life, and reduction in the incidence of nausea and leucopenia, but with no significant difference among the seven CMIs. Probability ranking result showed a great possibility for Shenqi Fuzheng and astragalus polysaccharide injections in improving the overall response rate and quality of life, which were followed by cinobufagin and kangai injections. However, only one study was included for Shenqi Fuzheng and astragalus polysaccharide injections. Therefore, cinobufagin or kangai injections were preferred in improving the overall response rate and quality of life. Aidi or compound sophora injections were better than other CMIs in reducing? the incidences of nausea (III-IV) and leukopenia. More RCTs of Shenqi Fuzheng and astragalus polysaccharide injections combined with radiotherapy for patients with esophageal cancer were expected in the future to confirm our results. Moreover, study findings will be reported, particularly for the adverse events in radiotherapy for esophageal cancer.

OBJECTIVETo analyze the expression level of candidate tumor suppressor gene N-Myc downstream-regulated gene 2 (NDRG2) in human colon cancer.

METHODSThirty samples of colon cancer tissues with matched normal colon tissues were collected. The NDRG2 mRNA level was detected by semi-quantitive RT-PCR and the NDRG2 protein level was examined by Western blot and immunohistochemistry.

RESULTSTwelve samples of colon cancer tissues had low NDRG2 mRNA level and low protein level. The positive rates of NDRG2 in normal tissues and the tumorous colon tissues were 90.0%(27/30) and 53.3%(16/30) by immunohistochemistry respectively. There was a significant difference between two groups (P<0.05). The NDRG2 expression was not correlated with age, sex, metastasis of lymph node, depth of infiltration, as well as the Dukes staging(P>0.05), while it was correlated to the histology grading. The positive rate of NDRG2 in the well- and moderate-differentiation group was higher than that in the poor-differentiation group(P<0.05).

CONCLUSIONThe expression of NDRG2 is low in some colon cancer tissues, which indicates that the low level of NDRG2 expression may be engaged in the development of colon cancer.

Objective To evaluate the association of cervical cancer and the G/C single nucleotide polymorphism at codon 72 in p53 gene exon -4 in Chinese population.Methods Literatures were searched in CNKI,VIP,CBM, PubMed,EMBase,the Cochrane Library (Issue 1,2015),WanFang Data Database (1980—2015)with computer. Results Thirteen studies involving 1 780 cervical cancer patients and 1 5 17 healthy volunteers were included.According to the situation of the HPV infection in research object,thirteen studies were divided into two subgroups.The results of meta-analyses in the subgroup of non-HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.980,95%CI:0.558 -1.723).The allele G showed no increased relative risk compared to the allele C (OR=1.070,95%CI:0.789-1.449)The results of meta-analyses in the subgroup of HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.891,95%CI:0.213 -3.722).The allele G showed no increased relative risk compared to the allele C (OR =0.981,95%CI:0.493 -1.951 ).Conclusion This meta -analysis demonstrates that G/C single nucleotide polymorphism at codon 72 in p53 gene exon-4 were not associated with cervical cancer in Chinese women.

Objective To observe the safety and efficacy ofintra-arterial thrombolysis guided by CT perfusion in patients with anterior circulation ischemic stroke presenting with symptoms longer than 6 h.Methods The clinical data of patients with anterior circulation ischemic stroke presenting with symptoms longer than 6 h (n=36) and shorter than or equal to 6 h (n=30),performed intra-arterial thrombolysis in our hospitals from July 2003 to December 2012,were retrospectively evaluated.Patients of the former group were evaluated the ischemic penumbra and core region of infarction and the mismatch between the two regions based on CT perfusion.The clinical features,clinical outcomes and complications were compared between the two groups.Results As compared with those in patients of symptoms shorter than or equal to 6 h,the early neurological improvement rate (13.3％ vs.22.2％) and long-term neurological improvement rate (86.7％ vs.77.7％),recanalization rate (80.0％ vs.88.9％) and 3-month mortality (6.7％ vs.16.7％) of patients of symptoms longer than were not significantly different (P=0.665,P=0.665,P=0.639 and P=0.607).Conclusions To patients with anterior circulation ischemic stroke presenting with symptoms longer than 6 h,the neurological function at 3-month significantly improves after intra-arterial thrombolysis guided by CT perfusion.Although the incidence of symptomatic intracranial hemorrhage increases,the mortality rate does not significantly increase.

OBJECTIVETo study the value and the clinical application of the Medical Image three-dimensional Visualization System of Abdomen (MI-3DVS) in diagnosis and evaluating resectability of pancreatic tumor.

METHODSTwelve patients with pancreatic tumor were tested with 64-slice helical CT (64-MSCT) angiography, and the CT data was reconstructed with MI-3DVS from November 2008 to August 2009. The 3D findings were adopted in diagnosis and evaluating resectability, and the results were compared with surgical operation and the pathological finding. There were 7 male and 5 female, aged from 14 to 83 years. Within the 12 cases, there were 4 cases with pancreatic carcinoma, 5 cases with pancreatic solid pseudopapillary tumor, 2 cases with pancreatic serous cystadenoma, 1 case with pancreatic cyst (ductal epithelial papillary hyperplasia).

RESULTSNine tumors which had been regarded as removable pre-operatively with MI-3DVS were removed successfully. Three patients who were considered unresectable by other hospitals with CT were operated successfully with MI-3DVS. The other 3 patients' tumors were actually not able to be removed as pre-operative evaluation.

CONCLUSIONMI-3DVS plays an important role in diagnosis and assessment of resectability of pancreatic tumor.

OBJECTIVETo analyze related factors which affect GPA mutation frequency of workers exposed to benzene, with the Glycophorin A (GPA) mutation assay and explore the possibility of GPA mutation frequency as an index of predicting the risk of benzene poisoning.

METHODSThe erythrocytes were bound with fluorescent-labeled monoclonal antibody after isolated and fixed from the peripheral blood, and then the GPA mutation assay was performed using the flow cytometry (FCM). The related factors of GPA mutation frequency were analyzed by statistical methods.

RESULTSThe GPA mutation frequency of chronic benzene poisonings was significantly higher than that of their controls (P < 0.05). Significant direct correlation was found between age, length of service, accumulative exposure score and the GPA mutation frequency of workers exposed to benzene (P < 0.01). However, there was significantly inverse correlation between the 3AB index and the GPA mutation frequency (GPAN0: r(s) = -0.589, P < 0.01, GPANN: r(s) = -0.615, P < 0.01). In the multiple factor regression analysis on GPA mutation frequency, benzene exposure and individual susceptibility both entered model of multiple factors analysis, the coefficient of determination of benzene-exposed workers was 0.819.

CONCLUSIONExposure to benzene and individual susceptibility are the most important factors that affect GPA mutation frequency. GPA mutation frequency increases with the benzene exposure and individual susceptibility.

OBJECTIVETo investigate the clinical value of glycosylated G-CSF combined with middle-high dose cyclophosphamide (Cy) or conventional chemotherapy with increased dose of Cy for mobilizing peripheral blood progenitor cells in patients with tumor.

METHODSThirty patients from four hospitals in Beijing region were enrolled in this clinical study. Diagnoses of the patients were non-Hodgkin' lymphoma (n = 21), Hodgkin disease (n = 1), breast cancer (n = 7) and ovary cancer (n = 1). Autologous peripheral blood progenitor cells (APBPC) were mobilized by middle-high dose Cy or conventional chemotherapy with increased dose of Cy combined with G-CSF. G-CSF was given subcutaneously from the nadir of the white blood cell (WBC) count to the end of PBPC collection. The dosage of G-CSF was 250 microg/d in 29 patients and 500 microg/d in 1 patient. When WBC count was > 5 x 10(9)/L, APBPC were harvested with CS 3000 plus/COBE Spectra.

RESULTSThe average dosage of Cy was 3.95 g (2.3 g/m(2)). The doses of G-CSF were 3.1 approximately 6.4 microg x kg(-1) x d(-1). Thirteen patients (43%) were collected twice, 14 patients (47%) three times and 3 patients (10%) four times. All of the patients could tolerate the treatment regimens. Seven patients had bone pain after G-CSF injection and one was severe, one patient had headache and one had nausea and vomiting.

CONCLUSION250 microg glycosylated G-CSF combined with middle-high Cy or conventional chemotherapy with increased dose of Cy combined G-CSF is an optimal method for APBPC mobilization in tumor patients.

OBJECTIVETo investigate the effects of fosinopril sodium pre-treatment combined with ischemic postconditioning on rat serum and myocardial oxidative stress and proinflammatory cytokines post ischemia/reperfusion.

METHODSSixty Sprague-Dawley rats were randomly divided into sham group (n = 15), ischemia/reperfusion group (30 minutes in situ occlusion of the left anterior descending artery followed by 1 hour reperfusion, n = 15), IPoC group (30 minutes occlusion of the left anterior descending artery followed by 3 cycles of 10 seconds of reperfusion/10 seconds of ischemia before 1 hour reperfusion, n = 15) and fosinopril sodium group [pretreated with fosinopril sodium (0.9 mg×kg(-1)×d(-1) for 14 days) followed by IPoC protocol at 2 h after the last gavage, n = 15]. The arterial blood and heart samples were extracted after 1 hour reperfusion. Serum CK-MB and cTnT levels were detected by colorimetric method, myocardial infarction size was measured by nitrotetrazolium blue chloride staining, SOD content was examined by colorimetric method, MDA content was detected using thiobarbituric acid method, serum levels of Interleukin-1α (IL-1α), Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were examined by radioimmunoassay, IL-1α, IL-6 and TNF-α levels of myocardial tissue were detected by ELISA.

RESULTSCompared with I/R group, myocardial enzymes and infarction size were significantly decreased (P < 0.05, P < 0.01), serum SOD content was increased and MDA content was decreased (all P < 0.01), serum and myocardial levels of IL-1α, IL-6 and TNF-α were significantly reduced (P < 0.05, P < 0.05, P < 0.01) in IPoC group. Compared with IPoC group, fosinopril sodium pretreatment further reduced infarction size and myocardial enzyme CK-MB (P < 0.05), increased SOD content (P < 0.05) while reduced serum IL-6 and myocardial tissue TNF-α (P < 0.05, P < 0.01).

CONCLUSIONPretreatment with fosinopril sodium enhanced the protective effect of IPoC on rat myocardium underwent I/R injury, possibly by reducing oxidative stress and early inflammatory reaction.
