Objective To summarize the experience of nursing cooperation in endoscopic sinus surgery for low temperature plasma radiofrequency ablation of skull base tumor, and to explore the safety and feasibility of this technique. Methods A total of 69 patients with skull base tumor were treated with low temperature plasma radio frequency technology to remove skull base tumor. Results Totally 62 cases of skull base tumors completed total resection in low temperature plasma radiofrequency ablation, 7 cases gained subtotal resection. The operation demonstrated superior advantage of less bleeding, short operation time, less postoperative pain and no adverse events. Conclusions The skull base tumor resection for patients with skull base tumors with low-temperature plasma radiofrequency possesses the advantages of short operation time, less bleeding and thermal damage to the surrounding tissues, besides it can reduce the postoperative discomfort, shorten hospitalization time and reduce the occurrence of nursing adverse events.

In recent years,the influencing factors of prognosis and effect after radiotherapy in breast cancer patients with radical mastectomy or modified radical mastectomy have gradually become a hot research,and it is closely related with the stages,subtypes,hormone levels and the body mass index (BMI).Otherwise,from three dimensional conformal radiation therapy to helical tomotherapy,the development of radiation technology has a breakthrough progress and makes the treatment of diseases more accurate and rational.

Objective To investigate the effect and the underlying mechanism of miRNA (miR)-506 regulating transforming growth factor-β1 (TGF-β1)-induced endothelial-mesenchymal transition of human aortic endothelial cell lysates.Methods In this study,miR-506 and inhibitory members of the ASPP family (iASPP) were selected as the study objects.First,the expression of miR-506 in human aortic endothelial cell lysates (HAEC) lysate was detected under different concentrations of TGF-β1.The expression of platelet endothelial cell adhesion molecule-1 (CD31),endothelium-cadherin (VE-cadherin),fibroblastspecific protein-1 (FSP1),α-smooth muscle actin (α-SMA) and N-cadherin was determined after miR-506 mimics/mimic negative control (NC) transfection into HAEC treated with or without TGF-β1.Then the expression levels of iASPP in miRNA-506 mimics/mimic NC-transfected HAECs treated with or without TGF-β1 were determined.Finally,the protein expression of CD31,VE-cadherin,FSP1 and α-SMA in HAEC transfected with miR-506 mimics/mimic NC was determined after iASPP overexpression.Results TGF-β1 can induce human aortic endothelial cell mesenchymal transition,down-regulate CD31 and VE-cadherin expression while up-regulate FSP1,α-SMA and N-cadherin expression;TGF-β1 inhibited miR-506 expression,promoted iASPP expression;miR-506 transfection into HAECs up-regulated CD31 and VE-cadherin expression while up-regulate FSP1,α-SMA and N-cadherin expression;miR-506 could downregulate the expression of iASPP;the overexpression of iASPP increased the expression of FSP1,α-SMA and N-cadherin,down-regulated CD31 and VE-cadherin and promoted the transformation of human aortic endothelial cells.Conclusions The transfection of iASPP plasmid promoted the endothelial-mesenchymal transition of human aortic endothelial cell lysates.The transfection of miR-506 inhibited the expression of iASPP and inhibited the endothelial-mesenchymal transition of human aortic endothelial cell lysates induced by TGF-β1.

Biosplint splinting ribbons and flowable restorative were used to stabilize the mobile anterior teeth and replace the missed teeth with in 30 patients severe periodontitis.1 and 2 years after treatment the effective ratio was 86.7% and 83.3% respectively(P >0.05), probing depth and attchment loss were decreased(P <0.05).

To observe the chelation of GRP78 with lead (Pb) and its localization changes, astroglial cells from Wistar rat brain were primarily cultured in medium with acetate Pb. The processes were terminated at different time points. The immunoprecipitation (IP) and Western blotting were used for GRP78 purification and expression and the Pb concentration was determined by employing atomic absorption spectrophotometry (AAS). The localization change of GRP78 was observed with colloid gold immunoelectron microscopy. The results showed that the expression of GRP78 was increased significantly in the cells treated with 1.0 mumol/L acetate Pb for 24 h and peaked at 96-192 h (P<0.01), and at the 12th day, the expression of GRP78 began to decrease but was still higher than normal (P<0.05). Pb content started to increase when cells were treated by acetate Pb for 24 h, and the peak appeared at 8 day (P<0.01), and then Pb content decreased gradually, but was still higher than normal (P<0.05). GRP78 protein expression began to remarkably increase when it transferred from ER to the cytosol around the nuclei 24 h after treatment with Pb. It is concluded that GRP78 in astroglia could strongly chelate with Pb ions and it might be a target protein of Pb.

Objective To evaluate serum organochlorine pesticides and residues levels in breast cancer pa-tients between the seriously and lightly earthquake-striken areas of Tangshan. Methods 93 patients of breast cancer from seriously earthquake-striken areas and 65 patients from lightly earthquake-striken areas were selected as study subjects,which serum organochlorine pesticides (DDTs and HCHs) levels were detected and compared with gas chromatography/electron capture. Results Serum organochlorine pesticides and residues levels in 158 patients be-tween the seriously and lightly earthquake-striken areas of Tangshan were not normal distributed. The order of detec-tion rate of HCH isomer in breast cancer patients between the seriously and lightly earthquake-striken areas were β-HCH>δ-HCH >α-HCH >γ-HCH. The orders of detection rate of DDT isomer in breast cancer patients between two areas of Tangshan were PP'-DDE > PP'-DDT > OP'-DDT > PP'-DDD. The serum levels of α-HCH,β-HCH, PP'-DDE and PP'-DDD in breast cancer patients between the seriously and lightly earthquake-striken areas were statistically different. Conclusion The levels of organechlorine pesticides and residues in serum with high detection rate in seri-ously earthquake-striken area are higher than that in lightly earthquake-striken area. It is likely that there is an asso-ciation with a large number of organechlorine pesticides sprayed.
