Aim: To compare the stability of Endostar~(TM) and endostatin under different temperatures and pH using polyacrylamide gel electrophoresis( PAGE) and Western blot and to compare the activity of Endostar kept at 4 ℃ and 37 ℃ by inhibition of endothelial cell proliferation. Methods: Endostar and endostatin expressed by Phicha pastoris were kept at 4 ℃, and 37 ℃ for 96 hours, respectively. The electrophoresis of the samples was detected by reduced and non-reduced PAGE. The results were further confirmed by Western blot with rabbit anti-Endostar polyclonal antibody. The inhibitory effect of Endostar stored at different temperatures on HUVEC was also exam-ined by cell-based assay. Results: Single band at 20 kD was detected in all lanes of SDS-PAGE gel loaded with endostatin and Endostar samples under reducing condition. In acidic native PAGE with three different pH values, endostatin showed a smear characteristic, whereas Endostar showed a unique band in acidic non-continuous native PAGE. Although the smear phenomenon was also observed under two conditions of constant native elec-trophoresis, the major band of Endostar could be detected. Similar electrophoretic behavior was found for endosta-tin and Endostar stored at both 37 ℃ and 4 ℃ . Western blot showed similar results to those by PAGE. Furthermore, Endostar stored at these two temperatures also had identical inhibitory effect on proliferation of HUVEC. Conclusion: Endostar and endostatin exhibit similar thermostability at regular conditions, but Endostar was more stable than endostatin expressed in P. pastoris under acidic condition.

Objective To explore the therapeutic effect of erythropoietin (EPO)combined oral iron in patients with chronic congestive heart failure( CHF)accompanied by anemia. MethodsNinety six patients with CHF accompanied by anemia, whom were consecutively hospitalized from January 2007 to December 2009, were enrolled into this study. They were randomly divided into treatment group accepted routine anti-heart failure therapy combined EPO and oral iron, and control group solely accepted routine anti-heart failure therapy. After 6 months follow up, the changes of hemoglobin ( Hb ), cardiac function classification, left ventricular ejection fraction(LVEF) ,6-minute walking distance,readmission rate of CHF and cardiac death were compared between two groups. ResultsCompared with those before therapy, we found significant improvements of hemoglobin level ( [ 120. 12 ± 10. 42 ] g/L vs [ 86.40 ± 14. 30 ] g/L, P < 0. 01 ), cardiac function classification ( 2. 65 ± 0. 67 vs 3. 13 ±0. 61, P < 0. 01 ), LVEF ( [ 37.21 ± 4. 96 ]% vs [ 33. 92 ± 7. 28 ]%, P < 0. 01 ), 6-minute walking distance ( [ 443.52 ± 97. 39 ] mvs [ 379. 15 ± 59. 34 ] m, P < 0. 01 ) in treatment group after EPO combined oral iron administration. After 6 months follow up, we also found significant improvements of Hb level ( [ 120. 12 ±10. 42 ] g/L vs [ 86. 40 ± 14. 30 ] g/L, P < 0. 01 ), cardiac function classification ( 2.65 ± 0. 67 vs 2. 98 ± 0. 81,P<0.01),LVEF([37.21 ± 4.96]% vs [34.67 ±4.10]%,P < 0. 01),6-minute walking distance ( [443.52 ±97. 39 ] mvs [ 379. 15 ± 59. 34 ] m, P < 0. 01 ) in the comparison between treatment and control group. The readmission rate of CHF fell significantly in treatment group compared to control (20. 83% vs 39. 58% ,P < 0. 05 ). However, we found no significant difference in cardiac death rate ( 0% vs 4. 17%, P >0. 05). ConclusionTreatment of EPO combined oral iron could significantly improve the cardiac function,increase exercise tolerance,lower the readmission rate of CHF in patients with chronic congestive heart failure (CHF)accompanied by anemia.

Objective To analyse the diagnosis and treatment of testicular torsion. Methods The clinical data of 66 cases of testicular torsion were retrospectively analysed. Results Among the 66 cases,32(48.5%) paid the first medical visit within 10 h,and 24(36.4%)were confirmed diagnosis at the first visit.False negative results occurred with color Doppler flow imaging(CDFI),and 8 testicles were damaged due to the false negative diagnosis.Thirty-three patients without prophylactic contralateral orchidopexy were followed up for 6 months to 20 years,and one experienced recurrent torsion. Conclusion The testicular torsion must be considered when a sudden acute scrotum pain is occurred.Testicular damage is closely related to the torsion time,and delayed medical intervention contributes to the testicular damage.Highly suspected cases should be performed surgical exploration timely due to the false negative results with CDFI.Prophylactic contralateral orchidopexy is recommended.
