[Objective] To detect the expression of NAD(P)H oxidase (Nox) and the content of ROS in different malignant gliomas,and explore the influence of Nox and intracellular ROS levels in the survival,proliferation,and malignant phenotype of gliomas.[Methods]Thirty human glioma specimens (10 with grade Ⅰ and I1,10 with grade II and 10 with grade IV),performed resection in our hospital from August 2007 to August 2010,were collected in our study;another 10 normal brain tissues were collected as controls.Real time PCR was used to detect the mRNA expressions of Nox(1-5);ROS level was detected by flow cytometry and Nox4 protein level was detected by immunofluorescence and Western blotting.[Results] The Noxl-5 mRNA and protein levels and ROS content were significantly different between each 2 groups (P＜0.05);Nox4 mRNA expression and ROS level significantly increased following the increment of malignancy degrees (controls＜low-grade gliomas＜grade III gliomas＜ grade IV gliomas,P＜0.05);the Nox protein expression was low in controls while that in gliomas was high,and the higher malignancy of the tumors,the higher expression levels of the tumors.[Conclusion] Nox expression and ROS content have significantly positive relations with the malignancy of the tumors,which indicates that Nox expression and ROS content might paly important roles in the occurrence of glioma and malignant proliferation.

To study xanthones from the barks of Garcinia xanthochymus, the constituents were isolated by normal-phase and reverse-phase silica gel column chromatography from the EtOAc extract. Their structures were elucidated by spectral analysis. Three new xanthones were purified and identified as 1,2,5-trihydroxy-6-methoxyxanthone (1), 1,4,6-trihydroxy-5-methoxyxanthone (2), 1,2,7-trihydroxy-4-(1,1-dimethylallyl) xanthone (3).

OBJECTIVETo investigate expression of tissue transglutaminase (tTG) protein and its role in carcinogenesis of brain tumors.

METHODStTG protein was detected by immunohistochemical method in 62 astrocytomas, 18 oligodendrogliomas, 30 benign meningiomas, 30 pituitary adenomas and 10 normal brain tissues.

RESULTS(1) In brain tumors, tTG protein expression was heterogeneous locating in tumor and endothelial cells. (2) Immunoreactivity of tTG protein was significantly different between different grades of astrocytomas. (3) Expression intensity of tTG protein in glioma was higher than that in benign brain tumors. (4) Strong expression of tTG protein in tumor cell was obtained around the necrosis foci and apoptotic cells in astrocytomas.

CONCLUSIONStTG protein expression contributed to tumor malignant progression in malignant brain tumors.

Objective To understand the risk factors for postoperative pulmonary infection in patients undergoing spinal surgery,and put forward the intervention measures.Methods Patients who underwent spinal surgery in a hospital from May 2008 to June 2016 were analyzed retrospectively,they were divided into non-pulmonary infection group and pulmonary infection group according to whether they had postoperative pulmonary infection,clinical data of two groups were compared.Results A total of 612 patients who underwent spinal surgery were monitored,43 had postoperative pulmonary infection,incidence of postoperative pulmonary infection was 7.03％.Univariate analysis showed that 14 risk factors for pulmonary infection in patients after spinal surgery were as follows:length of hospital stay≥30 days,long-term smoking,chronic pulmonary disease,diabetes,number of surgical level≥2,general anesthesia,duration of operation≥4 hours,bleeding≥500mL,time of bed rest≥7 days,use of glucocorticoid,indwelling urinary catheter,mechanical ventilation,serum albumin＜30 g/L,blood glucose≥1 1mmol/L,and hemoglobin＜90 g/L(P＜0.05);while atomization inhalation was a protective factor(P＜0.05).Multivariate logistic regression analysis showed that 6 independent risk factors for pulmonary infection in patients after spinal surgery were as follows:length of hospital stay≥30 days,long-term smoking,chronic pulmonary disease,general anesthesia,time of bed rest≥7 days,and use of glucocorticoid(all P＜0.05),while atomization inhalation was a independent protective factor(P＜0.05).Conclusion Patients with pulmonary infection after spinal surgery is related to multiple factors,comprehensive and effective preventive measures should be taken according to the risk factors of postoperative pulmonary infection,so as to reduce the incidence of postoperative pulmonary infection in spinal surgery patients.

AIM:To investigate the effects of ethyl acetate(EtOAc)extract of Pleione bulbocodioides (Franch.)Rolfe on proliferation and apoptosis of human leukemia K 562 and HL-60 cells and the possible apoptosis path-way.METHODS:Human leukemia cell lines were treated with EtOAc extract of Pleione bulbocodioides at different con-centrations.XTT method was used to evaluate the viability of K 562 cells and HL-60 cells.The cell growth inhibition was calculated by Trypan blue exclusion test.The percentage of apoptotic cells was determined by flow cytometry,and 4,,6-dia-midino-2-phenylindole(DAPI)was used to observe morphological changes of the cells.The cell cycle was observed by pro-pidium iodide(PI)staining.The protein expression of Bcl-2, Bax, cleaved poly(ADP-ribose)polymerase(PARP), cleaved caspase-3,cytochrome C and apoptosis-inducing factor(AIF)wase determined by Western blot.RESULTS:The cell viability and proliferation were inhibited by EtOAc extract of Pleione bulbocodioides with IC50of(42.14 ±2.54)mg/L for HL-60 cells and(51.28 ±3.12)mg/L for K562 cells at 24 h.The results of Annexin V-FITC/PI and DAPI staining showed that EtOAc extract of Pleione bulbocodioides induced cell apoptosis in a dose-dependent manner.The apoptotic rate was increased compared with control group(P<0.05).The G2phase increased with typical cell apoptosis-induced mor-phological changes.The levels of pro-apoptotic proteins Bax,cleaved PARP and cleaved caspase-3 were increased, while Bcl-2 was down-regulated(P<0.05).Cytochrome C and AIF in cytosol,characteristic proteins of intrinsic mitochondrial apoptosis pathway,also increased with the concentration of EtOAc extract of Pleione bulbocodioides increasing(P<0.05). CONCLUSION:EtOAc extract of Pleione bulbocodioides significantly inhibits cell proliferation and induces cell apoptosis in human leukemia cell lines HL-60 and K562 through intrinsic mitochondrial apoptosis pathway.

Objective To observe the efficacy and safety of applying sirolimus-eluting stents in emergency percutaneous coronary intervention (PCI) for the patients with acute myocardial infarction (AMI).Methods In total,220 patients with AMI were enrolled in this study at Shanghai Tongji Hospital, divided into two groups,one with bare-metal stent and the other with sirolimus-eluting stent.Cardiovascular fatality,major adverse cardiac events (MACE) and target vessel revascularization (TVR) were observed one and six months after PCI in the two groups.Results There was no significant difference in overall fatality and MACE in the 1~(st) or 6~(th) months after PCI between the two groups.Three cardiogenic deaths occurred in bare-metal stent group with a fatality of 2.8 percent,and five deaths in sirolimus-eluting stent group with a fatality of 4.5 percent in six months after PCI.However,rate of restenosis in those with sirolimus-eluting stents was significantly lower than that of bare-metal stents (6.0 percent vs 16.1 percent,P
