Objective To study the effect of red cell and plasma protein parameters on progression, prognosis and recurrence of cerebral infarction. Methods Clinical data from 105 patients with cerebral infarction were analyzed. The pa?tients were divided into four paired groups:progressive stroke group and complete stroke group, short-term favorable progno?sis group and short-term unfavorable prognosis group, long-term favorable prognosis group and long-term unfavorable prog?nosis group, relapsed cerebral infarction group and not relapsed group by different criterion. The red cell and plasma protein parameters were compared between groups. Results There were significantly higher mean corpuscular volume(fL:85.92± 4.50 vs 83.79±4.64,t=2.164,P<0.05), red cell distribution width(fL:13.50±2.45 vs 11.90±2.90,t=2.694,P<0.01), globu?lin(g/L:27.46±4.33 vs 24.79±4.03,t=3.029,P<0.01)and lower albumin(g/L:39.00±3.86 vs 42.89±4.45,t=4.242,P<0.01)in progressive stroke group than those of complete stroke group. The elevated red cell distribution width, reduced albu?min were the risk factors of progressive stroke. In the short-term unfavorable prognosis group, red cell distribution width was significantly higher than that in short-term favorable prognosis group(fL:13.90 ± 2.45 vs 12.00 ± 2.12,t=2.905,P<0.01). The red cell distribution width was positively correlated with mRS scores assessed 3 months and 18 months after cerebral in?farction(P<0.01). Conclusion Progressive stroke rate increases in cerebral infarction patients with elevated red cell distri?bution and reduced albumin;Red cell distribution width has a certain reference value for forecasting the prognosis of cere?bral infarction .

OBJECTIVETo compare the clinical effects of the circumcision stapler, circumcision cerclage, and traditional circumcision in the treatment of phimosis and redundant prepuce.
METHODSUsing the circumcision stapler (group A), foreskin cerclage (group B), and traditional circumcision (group C), we treated 276 patients with phimosis or redundant prepuce. We made comparisons among the three groups in the operation time, intraoperative blood loss, intraoperative and 24-hour postoperative pain scores, and incidence of postoperative complications. Results: The operation time, intraoperative blood loss, and intraoperative pain score were (6.52 ± 2.45) min, (1.93 ± 0.82) ml, and 1.37 ± 0.68 in group A and (7.24 ± 1.86) min, (1.51 ± 0.72) ml, and 1.20 ± 0.79 in group B, all significantly lower than (28. 36 ± 4.22) min, (9.52 ± 3.29) ml, and 3.06 ± 0.75 in group C (P <0.05). The 24-hour postoperative pain score was remarkably higher in group B than in A and C (3. 18 ± 0. 82 vs 1. 85 ± 0. 63 and 1. 82 ± 0. 75, P <0. 05). The incidence rate of postoperative complications was markedly lower in group A than in B (5. 43% vs 14. 13%, P < 0.05), but with no significant differences between either A and C or B and C (P >0.05).
CONCLUSIONThe circumcision stapler, with its advantages of simple operation, minimal invasiveness, fewer complications, and better cosmetic result, deserves a wider clinical application.
