Electric fields have special biological effects for its heating and non-heating effects. Heating effects are about the technology of radio frequency and microwave thermotherapy while non-heating effects are alternating electric field and pulsed electric field. These electric fields have significant effects for tumor treating.

Girdin protein is a kind of actin binding protein,which has the complex molecular structure and takes part in a variety of signaling pathways related with causing cancer.The biological characteristics of Gir-din protein have close association with the proliferation and invasion of malignant tumor.Recent studies have shown that Girdin protein is closely related with occurrence and progress of breast cancer.Girdin protein expres-sion in breast cancer cells can not only promote the progress of breast cancer,but also affect the lymph node me-tastasis and prognosis.Therefore Girdin protein is expected as an independent biomarker to provide a new direc-tion for breast cancer treatment.

BACKGROUND:Previous studies have found that the expression level of miR-486 in glioma stem cels (CD133+) is significantly down-regulated compared with that in glioma non-stem cels (CD133-), but the effect of down-regulation of miR-486 on CD133+ cels remains unclear . OBJECTIVE: To explore the effect of miR-486 on CD133+ cels. METHODS:CD133+ glioma stem cels and CD133- glioma cels were separated from U87 cels by flow cytometer. miR-486 overexpression glioma stem cels were constructed by lipofection transfection. RESULTS AND CONCLUSION:After sorting and purification, the content of the CD133+ fraction was enriched up to 83.5%. The expression level of miR-468 in CD133+ glioma stem cels was obviously down-regulated compared with that in CD133- glioma cels. CD133+ glioma stem cels overexpressing miR-486 were fabricated successfuly. Results from in vitro experiments showed that miR-486 overexpression could dramaticaly decrease the proliferation of glioma stem cels, induce a cel cycle arrest in G1/S phase for CD133+ glioma stem cels and promote cel apoptosis. These findings suggest that miR-486 can be a suppressor of glioma stem cels, which offers a novel potential therapeutic target for glioma stem cels and human glioma.

Objective To investigate the safety and efficacy of a 3-pulmonary vein (PV) isolation approach in treating paroxysmal atrial fibrillation (AF). Methods Radiofrequency catheter ablation was used to eliminate PV potential in 11 patterns with frequent paroxysmal AF refractory to anti-arrhythmic agents. During sinus rhythm, PV potential was mapped in the left and right superior PVs and left inferior PV. The procedural success was defined as the elimination of PV potential in the 3 PVs. Restults PV potential was identified and abolished in a total of 24 PVs, mostly in the left and right superior PV. There was no pulmonary stenosis or other complications during or after the procedures. AF recurred in one patient after an average of 12 ± 3 month follow-up. Conclusions PV potemials were present mostly in the left or right superior PV. The 3-PVs isolation approach is safe and effective in preventing drug-resistant paroxysmal AF.

Objective To observe the effect of transperineal injection of botulin A toxin on patients with detrusor-external sphincter dyssynergia caused by spinal cord injury. Methods Transperineal injection of botulin A toxin were performed in 6 patients with spinal cord injury (3 with cervical spinal cord injury and 3 with thoraco-lumbar spinal cord injury) complicated by detrusor-external sphincter dyssynergia.55 U of botulin A toxin was injected twice separately. The interval between 2 injections was 3 days.Before treatment, the residual volume of urine after voiding was determined and the maximum urethral pressure was measured by urodynamic testing.One month after treatment the examination mentioned above was repeated. Results The decrease in residual volume of urine was (133.3?70.9)ml.The decrease in maximum urethral pressure was (35.4?25.8)cmH 2O(both P

Objective: To detect the expression profile of NDRG1 gene in different tissues and cell lines and explore the relationship of NDRG 1 with liver tissue differentiation and hepatocarcinogenesis. Methods: The expression profiles of NDRG 1 in hepatocellular carcinoma (HCC) tissues, paired noncancerous liver (PNL) tissues, adult normal liver (NL) tissues, baby mouse liver tissues and fetal liver tissues in different developmental stages and cultured cell lines were performed using RT PCR and Northern Blot analysis. Results: Expression of NDRG 1 was significantly up regulated in HCC tissues compared to that of NL tissues and PNL tissues, however, the expressions of NDRG1 in NL and PNL tissues showed no evident difference. In ten cell lines, the highest expression was in the 293T human kidney cell line, the next one in liver cell L02, and the lowest one in the undifferentiated HLE cell line. Expression of NDRG1 in liver tissues enhanced with the development of the baby mouse and human fetus. Conclusion: NDRG 1 is probably related to the liver cell differentiation and is highly expressed in the specific stage of the differentiation. However, it could not be recognized as a marker of differentiation. The high expression of NDRG 1 in HCC indicates that HCC is not just distributed to a simple de differentiation. Much more study is necessary in understanding the comprehensive relationship of the disorder proliferation and differentiation of HCC and the related genes.

Objective To explore the role of hemoglobin (Hb) level in mortality and morbidity of chronic kidney disease (CKD)patients,aiming to give some evidence for therapy of anemia.Methods Randomized,clinical trials (RCTs) were identified by searching Medline,Embase and the Cochrane library.All the analyses were performed using the Revman software available free from the Cochrane collaboration.Results Twenty-three trials involving 10 204 patients were identified.Overall,the high Hb target was associated with increased risk of all-cause mortality (RR=1.10,95％ CI 1.00 to 1.21),hypertension (RR=1.40,95％ CI 1.12 to 1.75),stroke and hospitalization (RR=1.07,95％ CI 1.00 to 1.14) compared with low Hb target (P＜0.05).No significant difference was found in the risks of non-fatal mycardial infarction (RR=1.13,95％ CI 0.79 to 1.62) and renal replacement therapy (RR =1.00,95％ CI 0.85 to 1.18).Conclusions Targeting low Hb target is beneficial to CKD patients based on reduced risk of hypertension,hospitalization,stroke and all-cause mortality.However,no significant difference is found in non-fatal mycardial infarction and renal replacement therapy.
