Objective To investigate the correlation among lymph node metastasis and clinical features,postoperative survival rate in rectal cancer.Methods Seventy-nine patients who had accepted total mesorectal excision(TME) were collected,and the correlation among their clinical features(including gender,age,tumor size,gross type,depth of infiltration,histology type,differentiated degree and the level of blood serum CEA),lymph node metastasis,and postoperative survival rate were analyzed.Results There was significant correlation between six factors(namely the tumor size,gross type,depth of infiltration,histology type,differentiated degree and the level of blood serum CEA) and lymph node metastasis in single factor analysis.However,multivariate analysis showed that only gross type of tumor and depth of tumor infiltration were related to lymph node metastasis.The postoperative survival time of 43 non-metastasis cases was remarkably longer than that of 33 cases with lymph node metastasis(?2=18.806,P=0.000),and it was longer in 22 cases with

Objective To discuss the clinical effect of aspirin combined with clopidogrel therapy in pa?tients with transient ischemic attack( TIA)/light stroke. Methods One hundred and forty?eight cases with tran?sient ischemic attack/light stroke were divided randomly and voluntarily into the control group( n=74) and ob?servation group( n=74) . The patients of the control group were given aspirin based on conventional treatment while the observation group were given clopidogrel based on control group treatment. The serum C?reactive pro?tein(CRP),incidence of early neurologic deterioration(END),recurrence rate within 90 days,degree of nerve function defect score (NIHSS score),clinical effect after treatment and the complications during treatment be?tween the two groups were compared. Results After one week treatment,the serum CRP level of observation group decreased obviously compared with pre?treatment ( ( 6. 24 ± 1. 63 ) mg/L vs. ( 12. 03 ± 2. 46 ) mg/L , t=5. 625,P=0. 027),and the control group((9. 34±1. 24) mg/L,t=4. 348,P=0. 036),and there was not sig?nificantly reduced in the control group( t=2. 647,P=0. 186) . The incidence of END and recurrence rate within 90 days of observation group were evidently lower than that of control group(6. 76%(5/74) vs. 21. 62%(16/74) ,1. 35%( 1/74) vs. 8. 12%( 6/74);χ2=6. 737,5. 742,P=0. 022,0. 029) . The NIHSS score at 2 weeks af?ter treatment of observation group evidently lower than that of control group,the differences were statistically sig?nificant((2. 31±1. 03) points vs. (5. 34±1. 25) points;t=4. 663,4. 928). The effective rate of observation group was obviously higher than that of control group,the differences were statistically significant(93. 24% vs. 63. 51%,χ2=6. 253,P=0. 029) . There was no statistically significant differences about complications during treatment in both groups. Conclusion Aspirin combined with clopidogrel therapy can obviously improve nerve function,reduce progress of stroke and improve the clinical effect in patients with transient ischemic attack/light stroke,it is worth popularization and application.

Objective To discuss the clinical significance of change of serum uric acid (UA),C-reactive protein(CRP) and fibrinogen(Fg) levels in patients with acute cerebral infarction.Methods Ninetysix patients with acute cerebral infarction were divided into the mild group (n =52),middle group(n =32) and heavy group(n =12) according to illness degree,and 90 healthy person were selected as the control group.The serum UA,CRP and Fg of all groups were compared.Correlation analysis of serum UA,Fg and CRP in patients with acute cerebral infarction was carried.Results The level of serum UA((423.6±46.5) μmol/L vs.(302.4±28.7) μmol/L,t=4.758,P＜0.05),CRP((15.6±2.3) mg/L vs.(1.9±0.8) mg/L,t =14.547,P＜0.05) and Fg((4.6± 1.4) g/L vs.(3.1 ±0.9) g/L,t =3.936,P＜ 0.05) of acute cerebral infarction group were all obviously higher than that of control group,the differences were statistically significant(P＜0.05).The levels of serum UA((366.2±23.5) μmol/L,(398.4± 32.7) μmol/L and (457.4± 56.2) μmol/L,F =7.646),CRP ((7.4±1.6) mg/L,(14.6±1.9) mg/L and (22.8±4.6) mg/L,F=9.837) and Fg((3.3±1.4) g/L,(3.9 ± 1.5) g/L and (5.2 ± 2.1) g/L,F =5.757) of mild,middle and heavy groups rise with illness degree,differences were all statistically significance(P＜0.05).Correlation analysis showed that serum UA,CRP levels and Fg,CRP were positively correlated (r =0.683,0.564),the differences were statistically significant (P ＜0.05).Conclusion Serum UA,CRP and Fg levels in patients with acute cerebral infarction obviously increase and they can be regarded as to predict risk factors of cerebral infarction.
