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 .

Objective: To analyze the mortality trend of bladder cancer among residents in Qidong, Jiangsu Province from 1972 to 2016, so as to provide the basis for the prevention and treatment strategy of bladder cancer in Qidong. Methods: The data of bladder cancer was collected from Qidong Cancer Registry.The crude mortality rate ( CR ), age-standardized rate by Chinese population in 2000 (CASR) and world population in 1960 ( WASR ), truncated rate (35-64 years) and cumulative rate ( 0-74 years ) were calculated. The annual percent change ( APC ) was used to analyze the trend of mortality in bladder cancer. Results: During from 1972 to 2016, There were 1 497 deaths due to bladder cancer in Qidong from 1972 to 2016. The CR, CASR and WASR were 2.96/105, 1.83/105 and 1.80/105, respectively. The APCs in CR, CASR, WASR of bladder cancer were 5.29%, 1.86% and 1.81%, respectively ( P<0.05 ), showing upward trends. The truncated rate, cumulative rate and cumulative risk were 1.47/105, 0.17% and 0.17%, respectively. The CR, CASR and WASR in males were 4.71/105, 2.97/105 and 3.31/105, respectively, which was higher than that of 1.26/105, 0.75/105, and 0.66/105 in females ( P<0.05 ). The APC of CR, CASR and WASR in males were 5.71%, 1.96% and 2.17%, respectively ( P<0.05 ), all showed upward trends. For females, the APC of CR was 4.47% ( P<0.05 ), showing an upward trend, but there was no significant change in CASR and WASR ( P>0.05 ). The CR of bladder cancer was high among people aged more than 55 years. The CR in 55-64-year-old group, 65-74-year-old group and more than 75-year-old group showed upward trends, with APC of 4.50%, 2.22% and 4.51%, respectively ( P<0.05 ). Conclusions From 1972 to 2016, the mortality of bladder cancer in Qidong showed an upward trend, which was relatively high in men and people aged over 55 years.

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.
