Background and purpose: Cerebral gliomas is one of the common brain tumors, and has a poor prognosis. Therefore, multidisciplinary treatment strategy has been much investigated recently. This study investigated the efficacy of 3 dimensional conformal radiotherapy (3D-CRT) concurrent with Temozolomide chemotherapy in the treatment of postoperative cerebral gliomas. Methods: Sixty-two patients with cerebral glioma who had residual tumor surgery after surgery were randomized into 3D-CRT group (radiotherapy group, n=31) and 3D-CRT concurrent chemotherapy group (chemoradiotherapy group, n=31) prospectively. All patients received a dose of 50-60Gy/25-30F/5-6 weeks by 6MV-X ray, 1fx/day, 5 times a week. Chemotherapy regimen was Temozolomide: 75 mg/(m~2·d),concomitantly with radiotherapy,followed by 150-200mg/(m~2·d)for 5 days,28 days per cycle for total 3-6 cycles. Results: The total response rate was 35.3% (11/31) in the radiotherapy group, and 61.3% (19/31) in the chemoradiotherapy group. The difference was significant (P=0.042). But no significant difference was observed in terms of survival in the two groups (P=0.263). Stratified analysis showed that patients with grade Ⅲ gliomas in chemoradiotherapy group had better prognosis than those in the radiotherapy group (P=0.043). Conclusion. 3D-CRT concurrent with chemotherapy can improve the survival of pathological grade Ⅲ gliomas.

Objective To evaluate prognostic factors of patients with cerebral postoperative glioma treated with three-dimensional conformal radiotherapy (3DCRT). Methods62 patients with cerebral glioma who had residual tumor received 3DCRT. Factors such as gender, age, location of the glioma, pathological type, pathological grade, degree of surgical resection, combined chemotherapy, radiation dose, Karnofsky score before treatment were analyzed to show wether the impact on prognosis, Drawing survival curve with the Kaplan-Meier method, Log-rank test for univariate analysis and multivariate analysis were performed by using COX regression model.ResultsLast follow-up time was April 1, 2009. Median follow-up was 22 months, 43patients died. The 1-, 2- and 3-year overall survival rate were 65.7 %, 34.2 % and 20.5 %. In univariate analysis, the survival was related to age (P=0.008), pathological grade (P=0.016), degree of surgical resection (P=0.000), Karnofsky score before treatment (P =0.018). In COX multivariate modal, age (P =0.031), degree of surgical resection (P =0.000), Kamofsky score before treatment (P =0.035) were independent prognostic factors. ConclusionAge <40 years, Karnofsky score before treatment ≥70 and mostly resection are independent factors for predicting better survival of glioma patients.

Objective To compare the value of color Doppler echocardiography in the diagnosis of coarctation of the aorta (COA) in comparison with CT angiography (CTA). Methods Ninety-two patients with COA were retrospectively analyzed that were confirmed by surgery from January 2009 to September 2013 and diagnosed by color Doppler echocardiography and CTA. Results Among 92 COA patients conifrmed by surgery, 87 patients were diagnosed correctly by echocardiography while 91 patients were diagnosed by CTA, and the accuracy of echocardiography and CTA were 95%(87/92) and 99%(91/92), respectively without significant difference (χ2=1.550, P=0.213). According to surgical findings, there were 222 anatomic abnormalities including 110 intra-cardiac, 13 heart-vessel connection and 99 vessel abnormalities. For 110 intra-cardiac abnormalities, echocardiography detected all abnormalities while CTA found 92 with 18 missed including 11 valve or valve ring lesions, 3 patent foramen ovale, 2 atrial septal defect, 1 ventricular septal defect and 1 endocardial cushion defect. The accuracy of echocardiography for intra-cardiac abnormalities was signiifcantly higher than that of CTA (100%, 110/110 vs 84%, 92/110,χ2=18.801, P=0.000). CTA and echocardiography detected all abnormalities of heart-vessel connection. For 99 vessel abnormalities, CTA showed an accuracy of 98%(97/99) with 2 missed lesions including 1 collateral circulation between the aorta and the pulmonary artery and 1 membranous narrow of the aorta, while echocardiography misdiagnosed 1 COA as interruption of aortic arch and missed 15 lesions, including 4 COA, 3 collateral arteries, 2 patent ductus arteriosus, 2 aberrant right subclavian artery, 2 brachiocephalic vein abnormality, 1 partial anomalous pulmonary venous drainage and 1 persistent left superior vena cava. The accuracy of CTA for detection of vessel abnormalities was signiifcantly higher than that of echocardiography (98%, 97/99 vs 84%, 83/99,χ2=11.350, P=0.000). Conclusions Both CTA and echocardiography are effective diagnostic modalities for COA and CTA is superior to echocardiography for detecting vessel anomalies whereas echocardiography is superior to CTA for detecting intra-cardiac abnormalities. The combination of both modalities will provide more accurate information for clinical diagnosis.

Objective To investigate the effect of long hairpin RNA ( lhRNA) expression vector targeting HBV X gene ( HBx) on replication of hepatitis B virus ( HBV) and gene expression.Methods Four kinds of small interference RNAs ( siRNAs) were synthesized and lhRNA expression vectors targeting HBx were constructed.Four siRNA oligonucleotides and two lhRNA expression vectors were transfected into HepG2.2.15 cells.HBsAg, HBV DNA in culture supernatants and HBx mRNA in HepG2.2.15 cells were detected by time-resolved immunofluorometric assay, real-time quantitative PCR, and reverse transcription PCR, respectively.Negative sequence group or empty vector group was taken as the control.Independent-samples t test was performed to evaluate the inhibition effect on replication of HBV and gene expression. Results Compared with the negative control, HBsAg, HBV DNA level in culture supernatants and HBx mRNA in HepG2.2.15 cells were significantly decreased after siRNA-1 and siRNA-4 transfected at high concentrations (60 nmol/L or 90 nmol/L) (P<0.05), especially the HBsAg and HBV DNA levels in the siRNA-1 transfection group, which were significantly decreased at 24, 48 and 72 h after transfection ( P<0.05 or P <0.01 ) . Two lhRNA expression vectors ( pMD-HBxlh1 and pMD-HBxlh4 ) were successfully constructed and transfected into HepG2.2.15 cells, HBsAg and HBV DNA level in transfected cells was significantly lower than those in negative control (P<0.05).Conclusion The novel siRNA-1 is confirmed to target HBx gene and lhRNA expression vector targeting HBx can effectively inhibit the replication of HBV and expression of HBV gene.

Objective To investigate the effects of ISO-1, a selective MIF tautomerase activity inhibitor, on liver metastasis in a BALB/c mouse model of colonic cancer. Methods Micmporous migration assay was used to determine the effect of ISO-1 on the invasion abilities of CT26 cells. Orthotopic transplantation of fresh colonic tumor fragments into the hernial sac of cecum was used in a BALB/c mouse model of eolorectal cancer. Thirty mouse models were divided into three groups and treated respectively with ISO-1 (0. 2 ml, 20 mg/kg), 5% DMSO and NS ( normal sodium) twice a week, iutraperitoneally. After 4 weeks, mice were sacrificed and the whole livers were made into serial slices to detect the occurrence of liver metastasis. Serum MIF tautomerase activities were measured using L-dopachrome methyl ester, ELISA was used to test serum VEGF concentrations. Immunohistochemical staining of CD31 was used for comparing microvascular density (MVD) of tumor tissues. Results 100 μmol/L ISO-1 treatment for 24 hours significantly reduced the average number of the cells penetrating polycarbonates, ( 151 ± 19 ) vs. ( 178 ± 9 ), P<0. 01. Serum MIF tautomerase activities were significantly inhibited after ISO-1 treatment (51% vs. 81%, P <0. 01 ). Compared with DMSO and NS treatment, ISO-1 decreased the occurrence of liver metastasis ( 10% ,60% and 70% ,respectively;x2 = 8. 30, P < 0. 05 ). Also ISO-1 decreased serum VEGF levels ( 15 ± 7 ) pg/ml, ( 63 ± 11 ) pg/ml and ( 67 ± 8 ) pg/ml, respectively; P < 0. 01 and the MVD of tumor tissues (17±4) ,(36±7) and( 38±5) ,respectively; P<0. 01. Conclusion In vitro ISO-1 inhibits the invasion ability of CT26 cells. In vivo ISO-1 reduces the occurrence of liver metastasis, possibly by a mechanism of inhibiting MIF tautomerase activities, down-regulating the expression of VEGF and reducing MVD.

Objective To investigate the correlation between serum level of insulin growth factor 1 (IGF-1) and the degree of liver fibrosis in patients with chronic hepatitis C (CHC) complicated to type 2 diabetes mellitus (T2DM). Methods The cases were divided into CHC with T2DM (39 cases), CHC (96 cases), T2DM (60 cases), and healthy control (60 cases) groups. Their human data were collected and the fasting blood glucose, insulin and insulin-like growth factor-1 levels were detected, and the insulin resistance index ( HOMA-IR) wwer calculated. The serum levels of alanine transaminase ( ALT) , aspartate transaminase ( AST) , hepatitis C virus ( HCV) RNA load and HCV genotypes were detected simultaneously in patients with hepatitis C, and liver stiffness were measured ( LSM) by transient elastography ( TE) and aspartate aminotransferase-to-platelet ratio index ( APRI) score was performed. Results ⑴ There was no significant difference between CHC with T2DM group and CHC group in diabetes family history(P>0. 05), but two groups were significantly lower than that of T2DM group (P<0. 05). ⑵The levels of fasting insu-lin (FI) and HOMA-IR in CHC with T2DM group and T2DM group were significantly higher than those in the other two groups (P<0. 05), while the levels of IGF-1 in two groups were significantly lower than those in the CHC group, and were more lower than the control group (P<0. 05). ⑶Compared the serum ALT, AST and HCV RNA load between CHC with T2DM group and CHC group, there had no significant differ-ence (P>0. 05);however, the proportion of 1b genotype, LSM and APRI score of CHC with T2DM group were significantly higher than those in CHC group(P<0. 05). ⑷ The level of serum IGF-1 was negatively correlated with HOMA-IR, LSM and APRI in CHC with T2DM group (r= -0. 71, -0. 75, -0. 69, P<0. 01). Conclusions The degree of hepatic fibrosis and the damage of IGF-1 synthesis in CHC patients with T2DM were significantly higher than those in non T2DM patients, which might be related to the insulin resistance caused by 1b genotype HCV infection.
