With the rapid development of nanotechnology, nano oncology medicine that is formed through the combination of nano science and oncology medicine has become an important field emerging in nano science. Because of its unique optical properties, the gold nanorod (GNR), that is a rod-shaped nano materials, has shown great potential applications in the biomedical field, especially, in GRNs thermotherapy, radio-sensitizing effect therapy and targeting therapy of the tumor. Being a newly-developed therapy, gold nanorods combined with internal radiotherapy has already obtained excellent durative effect in targeting therapy of tumor. This paper aims to make a comprehensive review about its mechanism and its clinical application and research situation in recent years.

Objective To investigate the accuracy of liver volume measurement in patients with primary hepatocellular carcinoma by using the 3D + medical imaging visualization processing system. Methods Thirty patients who were clinically diagnosed as primary hepatocellular carcinoma and underwent surgical resection before preoperative assessment were selected from January 2016 to November 2016. Preoperative thin-slice CT images were transferred into the 3D + medical imaging visualization processing system for hepatic volume measurement, the predictive resection volume were measured and statistically analyzed with that of intraoperative specimen according to water measurement method. Results All patients had complete resection of tumor, the average volume of predictive resection calculated by the 3D software was (408.84 ± 177.07) ml, the average volume of intraoperative specimen measured by the water test was (399.95 ± 176.15) ml, the difference was not statistically significant (t=1.502, P=0.144), and the average percentage error was (6.21 ± 4.73) %. Pearson correlation analysis showed that there was significant correlation between them (r=0.983, P<0.05). Conclusion 3D+medical image visualization processing system is a simple, intuitive and accurate method for liver volume measurement, which can provide the basis for the accurate measurement of liver volume and the implementation of complex hepatectomy, and guide the precise hepatectomy.

Objective: To investigate the role of anti-inflammatory cytokine IL-10 in the pathogenesis of asthma.Methods:IL-10 internal standards was constructed by restriction digest.The expression levels of IL-10 mRNA were determined in peripheral blood and induced sputum of 23 asthmatic patients by(RT-PCR) with this competitive internal standards. Results:There was no IL-10 mRNA expression in most of the asthmatics.IL-10 mRNA was detected in some catabatic patients.But IL-10 mRNA was readily detected in 29 normal subjects. Conclusion:Airway inflammation of asthma was related to the expression of IL-10 gene.Asthmatic patients may have difficulty in IL-10 synthesis with transcript.

Objective To evaluate the prognostic value of the neuron-specific enolase ( NSE ) and bispectral index ( BIS) in patient with mild therapeutic hypothermia ( MTH) after cardiopulmonary resuscitation ( CPR ) .Methods Forty-six patients with restoration of spontaneous circulation ( ROSC ) after CPR were treated with MTH.The BIS values were recorded and the serum NSE was measured at the following times:24 h, 48 h, and 72 hours after ICU admission.Neurological outcome was classified according to the Pittsburgh cerebral performance category ( CPC 1 to 5) at 3 months after ICU discharge.Results Fourteen patients had a good neurological outcome with CPC score 1-3, and thirty-two patients had a poor neurological outcome with CPC 4-5 at 3 month.Compared with good outcome group, the NSE values were significantly higher in the poor outcome group on day 2 and day 3 after admission [48 h: (90.1 ±42.7) ng/mL vs.(33.2 ±17.5) ng/mL;72 h: (95.4 ±37.0) ng/mL vs. (29.2 ±17.0) ng/mL, P<0.05].NSE increased markedly in the poor neurological outcome group at 48h and 72h, and decreased significantly in the good group at the same time [△NSE 24 h-48 h: (37.3 ±28.7) ng/mL vs.(-10.7 ±12.1) ng/mL; △NSE 48 h-72h: (5.3 ±13.2) ng/mL vs.(-4.0 ±4.5 ng/mL), P<0.05].Over the 72 h of monitoring, the mean BIS values were lower in the poor outcome group compared to the good outcome group at 48 h [ (39.2 ±24.1) vs.(78.0 ±12.4); 72 h: (45.7 ±26.4) vs.(89.0 ±7.3), P<0.05].Conclusions The values of NSE and BIS were effective prognostic indicators for the neurological outcome of patients with MTH after CPR.

Objective To induce mice bone marrow(BM) mono-nuclear cells into dendritic cells(DC) in vitro,and then produce function vaccine of anti-myeloma by bone marrow derived dendritic cells(BM-DC).Methods Mono-nuclear cells separated from mice bone marrow were cultured in tissue culture plastics which supplemented granulocyte-macrophage clonystimulating factor(GM-CSF),IL-4.During the 8 days,there were numerous of mature DCs outgrown,and then fused with SP 2/0 myeloma cells in logarithmic growth phase cultured with 8-azaguaine by polyethylene(PEG).The resulting purified DC/myeloma hybrids were generated by selecting with hypoxanthine-aminopterin-thymidine(HAT).The specific anti-tumor activity was examined in vitro.Results Mono-nuclear cells derived from BM cultured by supplement propriate cytokines milieu in tissue culture plastics,and then exposed to lipopolysaccharide(LPS).There were plenty of mature DCs appear as early as day 8,and exhibit dramatic veils of cytoplasm and extensive dendrites in their surfaces,high express CD11c(83.19%),major histocompatibility complex(MHC)-Ⅱ(95.25%),CD86(89.24%),their capacity to stimulate primary T cell responses in mixed leukocyte reaction(MLR) would be shown strongly.Hybrids could grow well through PEG fusion and HAT selection.These hybrids could stimulate naive T cells into cytotoxic T-lymphocyte(CTLs) directed against SP 2/0 myeloma,and exhibit strong specific killed ability.Conclusions BM-DCs is fused with tumor cells ensure the tumor associated antigens could be processed and presented effectively,and stimulate specific anti-tumor immunity so that prevent or cure this kind of tumor.So it's feasible in practice to produce anti-tumor vaccine by BM-DCs.
