ABSTRACT
Objective:To explore the effect of laparoscopic minimally invasive on anorectal dynamics and serum carcino-embryonic antigen (CEA) and carbohydrate antigen 724 (CA724) in patients with rectal cancer.Methods:38 cases of rectal cancer patients were selected as the research group from March 2014 to March 2016 and 40 cases of non neoplastic intestinal polyps as control group,Preoperative anorectal dynamics index (anal resting pressure (ARP),rectal resting pressure (RRP)and anal maximal contraction pressure (MSP),rectal maximum tolerated volume (MTV) of two groups were compared,Preoperative and 3 d,1,2 weeks after operation of serum CEA and CA724 levels were detected in the research group and the clinical curative effect was observed.Results:There was no significant difference of ARP,RRP,MSP,MTV before operation in research group compared with the control group(P＞0.05),and was significantly reduced 2,4 weeks after operation(P＜0.05),then gradually restored,and basically recovered to the preoperative level 12 weeks after operation.There was no significant difference of serum CEA and CA724 levels 3 d after operation compared with preoperative in research group (P＞0.05),and were significantly lower 1,2 weeks after operation compared with preoperative (P＜0.05).The clinical effective rate was 65.8％.Conclusion:Efficacy of laparoscopic minimally invasive in treatment of rectal cancer is effective,can effectively reduce the levels of tumor markers,although there are some influence on anorectal dynamics,but it can be returned to normal in the short term.
ABSTRACT
Objective To investigate the change and clinical significance of serum procalcitonin (PCT) level in patients with community-acquired pneumonia (CAP).Methods One hundred and forty-five CAP patients were enrolled.Serum PCT level was measured by immunofluorescent antibody staining method.CURB-65 score and pneumonia severity index (PSI) score were used to evaluate the severity of the patients with CAP.Correlations between PCT and blood white blood cell (WBC) count,serum C-reactive protein (CRP),PSI score,CURB-65 score,hospitalization duration and mortality were analyzed with Pearson correlation analysis,Logistic regression analysis and so on.Results Serum PCT in patients with CAP showed positively correlated with CURB-65 score and PSI score (r =0.606,0.943,P＜ 0.01 ),and serum PCT was also positively correlated with age,serum CRP and hospitalization duration (r =0.753,0.233,0.281,P ＜0.01),but it wasn't correlated with blood WBC count (r =0.152,P ＞0.05).Logistic regression analysis showed that each increment of 1 μ g/L for serum PCT would increase 2.828-fold for the risk of death in CAP patients.Conclusions Serum PCT predicts the sensitivity and specificity of CAP with a similar prognostic accuracy with CURB-65 score and PSI score.Serum PCT in patients with CAP correlates with hospitalization duration and mortality.Therefore,it is a promising prognostic marker to evaluate the severity and outcome of CAP.It may serve as a useful marker for clinicians to evaluate the severity and prognosis of CAP.
