DNA methylation is closely related to the genesis and development of glioma.The CpG islands hypermethylation in promoter region of DNA repair genes,cell cycle controlling genes,apoptosis related genes,tumor suppressor genes and invasion related genes are found in glioma.Finding the specific methylation profile and molecular marker of glioma is helpful for the pathology class,early diagnosis and prognostic evalua-tion.Meanwhile,DNA methylation has the characteristic of reversibility,which may provide new ways for the treatment of glioma.

Transcatheter arterial chemoembolization (TACE) was the preferred method of non-operation treatment for hepatocellular carcinoma (HCC).Radical resection of HCC remains difficult,extrahepatic metastasis was not easy to deal with,and repeated treatment aggravated the liver injury,so the long-term efficacy was poor.Sorafenib could control tumor angiogenesis and block the proliferation of tumor cells.A male patient with primary HCC and in the stage Ⅱb according to the Chinese clinical liver cancer staging system was treated by TACE combined with sorafenib and antiviral treatment in Henan Cancer Hospital.After the treatment,the intrahepatic lesions were inactive,and the pulmonary metastasis was partially relieved.The patient was followed up till May 2012,and the survival time was 39 months.The hepatic function was normal,and the hepatitis B virus (HBV) replication was negative.No intervention treatmentrelated complications were detected,and the KPS score was 100.

Atherosclerosis is the most important cause of ischemic stroke. microRNAs can play an important role in the lipid metabolism, vascular inflammatory response, angiogenesis, as wel as smooth muscle cel proliferation and phenotypic conversion, etc. by regulating the functions of vascular endothelial cel s, vascular smooth muscle cel s, and mononuclear macrophages. It is closely associated with the occurrence and development of atherosclerosis. This article mainly reviews the regulatory effect of microRNAs on lipid metabolism and vascular inflammatory response in pathogenesis of atherosclerosis.

Objective To assess the therapeutic outcomes of transcatheter arterial chemoembolization combined with percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis for primary hepatic carcinoma accompanied by portal vein tumor thrombus. Methods Thirty patients with primary hepatic carcinoma accompanied by portal vein tumor thrombosis of type Ⅱ and type Ⅲ were randomly divided into two groups. The Child-Pugh ratings (class A and B) of group A and B were 9 vs 9 (class A) and 5 vs 7 (class B) respectively (χ~2 = 0.201, P > 0.05). The constitution of Type Ⅱ and type Ⅲ portal vein tumor thrombus in group A and B were 8 vs 9 and 6 vs 7 respectively (χ~2 =0.002, P>0.05). The median values of ALT, TBIL, ALB and AFP in group A and B were 58.7U/L vs 70.5 U/L (W=191.5, P>0.05), 21.4 μmol/L vs 21.7μmol/L (W=203, P>0.05), 35.3 g/L vs 37.5 g/L (W = 214, P > 0.05) and 680 μg/L vs 873 μg/L (W = 179. 00, P > 0.05) respectively. Group A was treated with transcatheter arterial chemoembolization (TACE) using emulsion made up of adriamycin, cisplatin, mitomycin and ultraliquidlipiodol plus percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis using emulsion consisted of cisplatin and ultraliquidlipiadol, while group B was treated with TACE only as a control group. Survival analyses were performed via the Kaplan-Meier test in SPSS11.5 with the log-rank tests with an threshold of 0.05. Results The 3, 6 and 12 months survival cases of group A and B were 11 vs 10, 10 vs 3, and 7 vs 0 respectively. The median survival time of group A and group B were 14.0 months and 4.0 months respectively. The difference of the two groups was significantly (χ~2 =11.728, P<0.01). There was no severe side-effect related to therapy in both groups. Conclusion Comparing with the control group, TACE combined with percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis could significantly prolong the median survival time of patient with primary hepatic carcinoma accompanied by type Ⅱ and type Ⅲ portal vein tumor thrombosis.

Objective To assess the therapeutic effect of combination chemotherapy of gemcitabine and cisplatin by double way plus implantation of radioactive seed 125I implantation in treating stage Ⅲ non-small cell lung cancer. Methods Sixty cases with stage Ⅲ non-small cell lung cancer were randomly divided into two groups with random number table. In group A (in interventional treatment group, n = 30),the gemcitabine 1000 mg/m2 and one third of the cisplatin 100 mg/m2 was given using seldinger technique for transcatheter bronchial arterial infusion chemotherapy on day 1. Two-thirds of the cisplatin 100 mg/m2 was infused in veins on day 2 and 3. The gemcitabine 1000 mg/m2 was infused in veins on day 8, 21 days for a period. In group B (interventional - 125I groups), the method of combination chemotherapy of gemcitabine and cisplatin was the same as in Group A. After ten days of arterial perfusion, 125I seeds were implantated, 21 days for a period. All patients received at least 2 cycles. The imaging evaluation of patients after treatment standards included complete remission (CR), partial remission (PR), stable (SD),progressive disease (PD), effective rate (CR + PR)/30 and clinical benefit rate (CR + PR + SD)/30.Non-parametric rank sum test was used to compare short-term effect of the two groups treatment of two cycles.x2 test was used to compare year survival, Kaplan-Meier method was used to calculate median survival,log-rank test method was used to difference between the groups. Results In group A, there were 17 PR,9SD and 4 PD. The overall response rate was 56. 7% (17/30) and clinical beneficial rate was 86. 7% (26/30). In Group B, there were 2 CR, 21 PR, 7 SD. The overall response rate was 76.7% (23/30) and clinical beneficial rate was 100% (30/30). There was significant difference between the two groups (P =0. 036). In group A, the 1 year survival rate was 46. 7% (14/30) and the 2 year survival rate was 36. 7%(11/30), median survival time (MST) was 10 months . In group B, the 1 year survival rate was 76. 7%(23/30) and the 2 year survival rate was 63. 3% (19/30) , median survival time (MST) was 27 months.There was a significant difference between two group in 1 year survival rate (P = 0. 017), 2 year survival rate (P = 0. 039) and median survival time (P = 0. 006). Conclusion The treatment effects of Ⅲ stage non-small cell lung cancer by gemcitabine and cisplatin combination chemotherapy with double way plus radioactive seed 125I implantation was better than gemcitabine and cisplatin combination chemotherapy with double way.

Objective To observe the therapeutic effects of arsenic trioxide combined with transcatheter arterial chemoembolization on treatment of primary liver cancer with pulmonary metastases.Methods Sixty patients were randomly divided into two groups:group A (treatment group,n =30) and group B (control group,n =30).Group A was received periodic transcatheter arterial chemoembolization (TACE) and 10 mg arsenic trioxide by intravenous infusion for 5 hours per day,3 days after TACE.Each cycle consisted of 14 days' administration,and repeated after 2 weeks.Each patient was received 3-4 successive cycles.Group B was received periodic TACE alone.Objective efficiency,benefit rate,quality of life and the correlates with metastatic tumor size and number in the both groups were recorded.Results The objective efficiency was 26.7％ (8/30),and the benefit rate was 60.0％ (18/30) in group A,while they were 0 and 16.7％ (5/30) in group B with significant statistics differences (x2 =7.067,P =0.008;x2 =11.915,P =0.001).The quality of life was improved in 4 patients and stable in 18 of group A,while no patient was improved and 13 were stable in group B (x2 =9.669,P =0.008).There was a significantly positive correlation between the tumor burden and therapeutic effect (Kendall r =-0.765,P ＜ 0.001 ;Spearman r =-0.821,P ＜ 0.001).Conclusion Arsenic trioxide combined TACE is an effective treatment method in treating primary liver cancer with pulmonary metastases.

Objective This study was to investigate the value of CT guided 125iodine implantation combining transcatheter arterial chemoembolization(TACE) to prevent digestive tract bleeding in patients with portal vein tumor thrombus in primary hepatocellular carcinoma. Methods Forty patients with portal vein tumor thrombus which were diagnosed to have primary hepatocellular carcinomas by diagnostic criteria of Chinese Anti-Cancer Association were collected prospectively. They were divided into the treatment group and the control group, with 20 patients in each group. The treatment group was treated by TACE for hepatic tumor and 125iodine seed implantation for portal vein tumor thrombus, while the control group was treated by TACE for hepatic tumor and only given β-blockers medicines after treatment. Intraoperative and postoperative surgery-related complications were observed. Three months after surgery, enhanced abdominal CT scanning was performed to evaluate treatment effects which were divided into complete response (CR), partial response (PR), and progressive disease (PD) and stable of disease (SD), and the local tumor control rates were calculated. The bleeding rates and mortality after 3 months, 6 months, 12 months were recorded. Treatment effects of the two groups were compared with continuously correction Chi-square test, bleeding rates were compared with Fisher test, and survival rates were analyzed with Kaplan-Meier survival curve and compared with Log-rank test. Results Overall the 40 patients were treated successfully without serious surgery-related complications. In the treatment group, there were 8 patients with PR, 6 with SD and 6 with PD, and the local control rates were 40% (8/20). In the control group, there were 1 patient with PR, 6 patients with SD and 13 with PD. The difference of the local control rates was statistically significant (χ2=5.161, P=0.023).The bleeding rates at 3, 6 and 12 months were 2, 2 and 3 cases in the treatment group, for control group they were 2, 6 and 10 cases respectively. There was no statistical difference between the 3 months and 6 months bleeding rates (P values were 1.000 and 0.235), but for 12 months bleeding rates, the difference was statistically significant (P=0.041).The 1 year cumulative survival rates of the treatment group and control group were 70% (14/20) and 40% (8/20), and the difference was statistically significant (χ2=4.675, P=0.031). Conclusion The treatment of 125iodine implantation combining transcatheter arterial chemoembolization in patients with portal vein tumor thrombus in primary hepatocellular carcinoma can reduce variceal bleeding rate and improve survival rate.

Objective To investigate the association of serum leptin (LEP) levels during the first postpartum year with the occurrence of postpartum thyroiditis (PPT).Methods Fifty-seven PPT patients consisted of 34 with overt PPT and 23 subclinical PPT.37 healthy postpartum women were used as controls.Serum samples were obtained at 4 postpartum date points,i.e.3-days and 3,6,12-months postpartum.LEP level was determined by radioimmunoassav.Results Compared with control women,PPT patients were maintaining significantly higher levels of LEP and LEP/body mass index (BMI) ratio during the first postpartum year.There was no significant difference in serum LEP level or LEP/BMI ratio between overt PPT and subclinical PPT groups.In PPT patients,LEP and LEP/BMI ratio were negatively correlated with serum TSH,and positively correlated with serum FT4 and FT3.Conclusion Sustained high levels of serum LEP after delivery may favor the occurrence of PPT.Further studies are needed to clarify the specific role played by LEP in PPT.

Objective To assess the therapeutic effect of thermochemotherapy infusion combined with chemoembolization in the treatment of primary hepatocellular carcinoma.Methods Ninty six patients with hepatic carcinoma were randomly diveded into two groups.In A group,the patients underwent thermochemotherapy infusion combined with chemoembolization.In B group,chemotherapy infusion was done combined with chemoembolization.Before the therapy,the basic examinations of patients were improved,including liver function,renal function,immune function.At the same time,each patient was performed with enhanced CT scan.Three days and a month after treatment,main outcome measures,containing liver function,renal function,and immune function were examined,the volumes of tumor were measured on CT.Repeat treatment were performed between four and six weeks.Follow-up was performed after the third treatment,patients survival periods were observed.Results A and B groups of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were higher than pre-treatment after 3 days (all P ＜ 0.05),but the ALT and AST in group B were both higher than those in group A (P =0.001,P =0.002),there were no changes after 30 days.No significant difference of renal function were found in the both groups.In the A group,the total efficiency was 75.00 ％ (36/48),and that of the B group was 39.58 ％ (19/48),showing statistically significant difference (P ＜ 0.01).In the A group,the immunity state of patients were improved after treatment.In the A group,the median survival time was 24.0 months (95 ％ CI was 20-29 months).In the B group,the median survival time was 18.9 months (95 ％ CI was 18-20 months).There was significant difference between the two groups (P ＜ 0.01).Conclusion The gemcitabine transcatheter arterial heated chemotherapy combined carboplatin with transcatheter arterial chemoembolization is effective treatment for primary hepatocellular carinoma.
