Objective To explore the protective effect of co-treatment with antioxidants 4-hydroxy-2,2,6,6-tetra-methylpiperidine 1-oxyl (TEMPOL) and reduced glutathione (GSH) in pancreatic injury induced by intermittent hypoxia (IH) in mice. Methods Fifty male C57BL/6J mice were randomly divided into control group(CON), IH group (IH), IH+TEM-POL group (IH+TEMPOL), IH+GSH group (IH+GSH) and IH+TEMPOL+GSH group (IH+TEMPOL+GSH). After successful-ly prepared animal model, the insulin resistance (IR) level, pancreatic malondialdehyde (MDA) level,superoxide dismutase (SOD) activity,glutathione reductase (GR) concentration and pancreatic β-cell apoptosis were detected in five groups. Re-sults The blood glucose level was significantly increased in IH group than that in CON group (P<0.01), but which was sig-nificantly decreased in IH+TEMPOL+GSH group than that of IH group (P<0.01). The MDA content was significantly higher in the IH group than that in CON group (4.48±0.25 vs 1.94±0.21, P<0.01), but SOD activity and GR content were signifi-cantly lower in IH group than those of CON group (61.52±3.33 vs 100.05± 7.26,107.81±7.54 vs 170.54±4.90,P<0.01). The level of MDA was significantly lower in IH+TEMPOL+GSH group (2.07±0.35) than that in IH group. The levels of SOD and GR were significantly higher in IH+TEMPOL+GSH group (96.68±5.85 and 166.87±5.75) than those of IH group (P<0.01). The apoptotic rate of pancreaticβcells was significantly increased in IH group than that in CON group (2.43±0.07 vs 0.54± 0.06, P<0.01), but it was significantly lower in IH+TEMPOL+GSH group (0.56 ± 0.06) than that in IH group (P<0.01). There were no significantly differences in all above indexes between IH group, IH+TEMPOL group and IH+GSH group ( P>0.05). Conclusion The co-treatment with the antioxidant TEMPOL and GSH can obviously protect IH-induced pancreatic injury in mice. However, there was no significant protective effect of TEMPOL or GSH alone on pancreatic injury.

Objective To investigate the efficacy and safety of patients with malignant pleural effusion treated with injecting endostar combined with platinum complexes into pleural cavity.Methods Cochrane systematic review methods were used in the data selection,and data were selected from the PubMed,Embase,Cochrane Library,China National Knowledge Infrastructure (CNKI),WanFang,and VIP database to get all clinical controlled trials.The retrieval time was August 2014.The objects of these randomized controlled trials were malignant pleural effusion patients.Endostar combination with platinum complexes was used for the experimental group.Platinum complexes alone were used for the control group.The efficacy and adverse effects of two groups were compared.The quality of included trials was evaluated by two reviewers independently.The software RevMan 5.3 was used for meta-analyses.Results Nine trials with 488 patients were included according to the including criterion.All trials were randomized controlled trials,one of them had B level in quality and eight had C level.Meta analysis results were as follows:there was significant difference in overall effective rate (OR =3.52,95％ CI =2.37 ～ 5.22),Karnofsky (KPS) score changes rate (OR =2.64,95％ CI =1.67 ～ 4.19),between endostar combination with platinum complexes and platinum complexes alone group.The incidences of severe leucopenia (OR =1.0,95％ CI =0.62 ～ 1.61) and nausea and vomiting (OR =0.77,95％ CI =0.43 ～ 1.38) were similar in the endostar combination with platinum complexes group compared to those in the platinum complexes alone group.Conclusions In the treatment of malignant pleural effusion,injecting endostar in combination with platinum complexes into pleural cavity improves the effective rate without obviously raised side effects.Owing to the small sample size and poor quality of included trials,more well-designed double-blinded randomized controlled trials should be performed.

Objective To observe the clinical curative effect of selective bronchial arterial embolization for severe hemoptysis.Methods Thirty-eight hospitalized patients with severe hemoptysis was enrolled in this study.Of which 31 patients were recurrent hemoptysis,27 patients were with bronchiectasis,4 patients were with bronchial lung cysts,4 patients had unknown causes,3 patients were with tuberculosis.All patients were diagnosed by chest imaging examination,fiber bronchoscopy,bronchial arteriography,and they were all treated by selective bronchial arterial embolization.Results The most times of embolization was 3,and bronchial arterial imaging were performed for vascular malformation.After having bronchial arterial embolization,35 patients were immediately released of bleeding.Postoperative 24 h,8 patients had hemoptysis again,of which 1 case was performed with conservative treatment and subsequently had pneumonectomy,5 patients had effective conservative treatment,2 cases were performed embolization again after failed conservative treatments.Hemoptysis completely disappeared within 1 week.The total effective rate was 97.4％(37/38).Patients were followed up for 1 year,of which 13 patients relapsed again,11 patients'annual and each time's quantity of hemoptysis reduced 50％.Two patients had pneumonectomy after a number of embolization.The total effective rate was 94.7％ (36/38).After treatment,3 patients had mild chest pain in short time,2 patients had shoulder pain,3 patients had chest tightness,and 3 patients had subcutaneous passive congestion.After being treated for short-term,these symptoms disappeared eventually.Conclusion Selective bronchial arterial embolization for the treatment of acute or recurrent severe hemoptysis is very effective,and can avoid the risk of surgery.It is effective for recurrent cases and worthy of clinical application.

Objective To investigate the expressions of Livin and vascular endothelial growth factor (VEGF)in pancreatic carcinoma and their cilinical significances.Methods The expressions of Livin and VEGF proteins were tested by immunohistochemistry in 68 cases of pancreatic carcinomas and 44 cases of adja-cent paracancerous tissues.Results The positive rates of Livin in pancreatic carcinomas and adjacent paracan-cerous tissues were 73.5% and 4.5% respectively,and the difference was statistically significant (χ2 =48.137,P<0.001).The positive rates of VEGF in pancreatic carcinomas and adjacent paracancerous tissues were 69.1% and 13.6% respectively,and the difference was statistically significant (χ2 =29.147,P <0.001).The expressions of Livin and VEGF were related with tumor differentiation (χ2 =6.061,P=0.014;χ2 =6.592,P=0.010),TNMstage (χ2 =4.175,P=0.041;χ2 =9.992,P=0.002),lymph node metasta-sis (χ2 =11.731,P=0.001;χ2 =12.002,P=0.001)and neural invasion (χ2 =9.950,P=0.002;χ2 =7.433,P=0.006).Significantly positive correlation was found between the expressions of Livin and VEGF by using Spearman correlation analysis (r=0.320,P=0.008).Survival analysis showed that the expressions of Livin and VEGF were independent prognostic factors in pancreatic carcinoma.Conclusion Livin and VEGF involve in the development,migration and metastasis of pancreatic carcinoma.Livin may upregulate the expres-sion of VEGF,which may lead to the angiogenesis and migration in pancreatic carcinoma.

Purpose To probe into the value of M-mode echocardiography and spectral Doppler echocardiography in diagnosing fetal atrial premature beats.Materials and Methods Echocardiography examinations were given to the seventy-three fetuses around 16-40 gestational weeks which were found suffering from fetal arrhythmia in the clinical examinations by using M-mode echocardiography and spectral Doppler. Thirty-two of them were screened out with fetal atrial premature beats, and their ultrasonic cardiograms were analyzed. The follow-up visits were later conducted.Results Among the thirty-two cases with fetal atrial premature beats, fourteen were attacked frequently, and the other eighteen were attacked accidentally. Two cases were documented with muscular ventricular septal defect. Apart from two missing cases, the rest thirty cases were found to be recovered from arrhythmia before or after birth in the follow-up visits. The disappearance rate of atrialpremature beats in the fetuses attacked frequently by the disease before birth was clearly lower than that in those attacked accidentally (P<0.05). Muscular ventricular septal defect in the two cases were found closed after birth. Conclusion M-mode echocardiography and spectral Doppler echocardiography, as non-invasive imagining techniques to take antenatal examination of fetal arrhythmia, have advantages such as reliable, direct, convenient and can be used repetitively, therefore can provide important information for clinical treatment and prognosis.
