Objective To discuss the relativity between serum procalcitonin(PCT) level and renal impairment (RI) in critically ill patients. Methods A perspective study was performed in 60 critically ill patients. They were divided into 2 groups on the serum PCT level within 24 h: abnormal group (PCT ≥ 0.5 μg/L,38 cases) and normal group(PCT < 0.5 μg/L,22 cases). The serum creatinine (SCr) and blood urea nitrogen (BUN) were observed. Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) of the patients were recorded. Calculated the sensitivity and specificity for prediction of RI as well as acute renal dysfunction (ARD). Results SCr [(188.91 ± 199.48) μmol/L]and BUN [(13.03 ±9.19)mmol/L]in abnormal group were significantly higher than those in normal group [(67.40 ± 15.35) μ mol/L and (6.91 ± 2.06) mmol/L](P< 0.01). The sensitivity of PCT forecast RI was 71.79%, and specificity was 52.38%. The sensitivity of PCT forecast ARD was 91.67% , and negative predictive value was 95.45%. Conclusion Serum PCT level has an important value for judgement of RI and ARD in critically ill patients.

[Summary] This retrospective analysis showed that the level of apolipoprotein E was significantly higher in diabetic nephropathy group compared with normal albuminuria group [50.4 (40.8,65.9) vs 46.2 (38.6,56.8)mg/L,P＜0.01].Difference in urinary albumin to creatinine ratio (ACR) among the groups based on the tertile of apolipoprotein E were significant (P＜ 0.01).Multiple linear regression analysis demonstrated that apolipoprotein E was independently associated with ACR (β =0.14,P＜0.05).

Objective To evaluate the prognostic value of MTV measured by pretreatment 18F-FDG PET/CT imaging in patients with pancreatic cancer (PC).Methods The clinical data of 52 patients (31 males,21 females,median age 58.5 years) with pathologically or clinically proved PC from January 2011 to October 2014 were retrospectively analyzed.Serum CA19-9 was measured within 1 week before PET/CT examination.SUVmax and MTV were measured respectively,and PET/CT staging was obtained simultaneously.All patients were followed up until January 2015.The CA19-9,MTV,SUVmax,PET/CT staging and clinical factors(age,gender,treatment methods) were assessed by ROC curve analysis,Kaplan-Meier analysis and multivariate Cox model.Results The median survival time of 52 patients was (11.20±7.25) months.ROC curve analysis showed that the AUC of MTV,SUVmax and CA19-9 were 0.735,0.614 and 0.527 respectively.Kaplan-Meier survival analysis manifested that the survival times were significantly different between patients with different MTV (＜ 12.14 cm3 vs ≥ 12.14 cm3),different SUVmax (＜ 8.95 vs ≥ 8.95),different PET/CT staging and different treatment methods (x2 =4.272-11.693,all P＜0.05).The survival time of patients with MTV ＜ 12.14 cm3 and that of patients with MTV ≥ 12.14 cm3 were (13.44±8.40) and (7.00± 4.82) months,respectively.Cox single-factor analyses indicated that MTV,PET/CT staging and SUVmax were risk factors of survival,the hazard ratios (HR) were 0.393,0.503,0.547 respectively (P=0.002,0.020,0.027).Cox multi-factor analyses indicated that MTV and PET/CT staging were independent risk predictors of survival.Conclusion MTV and PET/CT staging are significant factors in prognosis prediction of patients with PC,which would be helpful to make individual treatment for patients with high risks.

Objective To explore the treatment effect and application value of ultrasonic guided mammotome minimally invasive whirling surgery and open surgery for benign breast tumor.Methods 264 patients with benign breast diseases were randomly divided into observation group and control group,132 cases in each group.The control group took open surgery,the observation group used mammotome minimally invasive surgery,rotary cutting system.Recorded clinical surgery treatment of the two groups.Results The operating time,intraoperative blood loss,operation scar size of the observation group were (18.27 ± 3.05) min,(10.86 ± 1.69) mL,(2.76 ± 0.85) mm respectively,those of the control group were (53.48 ± 6.17) min,(97.54 ± 14.28) mL,(27.63 ± 4.31) mm respectively,the differences between the two groups were statistically significant (t =58.7753,69.2560,65.0429,all P ＜ 0.05).In the observation group,breast deformation in 0 case,postoperative occurrence skin pigmentation in 1 case,itchy skin in 2 cases,with lateral swelling in 1 case,the patients' satisfaction score was (93.42 ± 3.89) points.In the control group,breast deformation in 5 cases,postoperative occurrence skin pigmentation in 8 cases,skin itching in 9 cases,lateral swelling in 7 cases,the patients' satisfaction score was (88.16 ± 1.45) points,the differences between the two groups were statistically significant(x2 =5.096,5.636,4.648,4.604,t =14.557,all P ＜0.05).Conclusion Using ultrasonic guided mammotome minimally invasive rotary surgical treatment for benign breast diseases can shorten the operation time,reduce intraoperative bleeding,reduce the incidence of postoperative complications,patients' satisfaction is higher,and it is worthy of popularization and application in clinic.
