ABSTRACT
Objective To investigate the risk factors which can lead to chronic kidney disease (CKD) after radical nephroureterectomy and guide adjuvant chemotherapy for the patients with upper tract urothelial carcinoma (UTUC).Methods 239 patients with UTUC,who were treated at our hospital from October 2010 to February 2015 was analyzed retrospectively.Serum creatinine levels were measured preoperatively and 1 month (range:21days to 35 days) after radical nephroureterectomy.129 males and 110 females patients were enrolled.Ages were from 41 to 94,and mean age was 66 years.All patients underwent radical surgery.The pathological stages included Ta/T1/T2/T3/T4,and grades included G1/G2/G3.We calculated GFR using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations in consideration of age,sex,and serum creatinine level.The new-onset CKD after RNU was defined as when the calculated CKD-EPI GFR decreased to less than 60 ml/(min · 1.73 m2).These patients were divided into 2 groups which depended on whether they got CKD after RNU.Cohorts were stratified by gender,age,smoking,BMI,hypertension,diabetes mellitus (DM),tumor location,tumor size,multifocality,pathologic stage,grade,hydronephrosis and preoperative CKD-EPI GFR.The chi-square test was used to examine the relationship among the various cohorts and the CKD after RNU.The Kaplan-Meier method was adopted to identify the relationship between Overall survival (OS).Cancer-specific survival (CSS) and CKD.Univariate and multivariate analyses were performed to study the relationship between clinical factors and CKD after RNU using the Cox proportional hazards regression model and chi-square test.Results In our study,the median follow-up time was 41.3 (range from 2-82) months for 239 patients.Median CKD-EPI GFR for all patients before and after surgery was 71.4 (65.2-108.7) ml/(min · 1.73 m2) and 54.7 (37.6-93.8) ml/(min · 1.73 m2),meanwhile 105 cases became new-onset CKD.There was no significant difference in overall or cancer specific survival between CKD + and CKD-(P =0.137,P =0.190).However age (HR =1.825,95％ CI 1.203-2.768,P =0.017),hydronephrosis (HR =0.243,95 ％ CI 0.106-0.613,P =0.034) and preoperative CKD-EPI GFR (HR =0.237,95 ％ CI 0.109-0.524,P =0.021) were significantly correlative with postoperative new-onset CKD.Conclusion Age,absence of hydronephrosis and preoperative CKD-EPI GFR were independent risk factors predicting new-onset CKD.They can be the predictor of new-onset CKD.

ABSTRACT
Objective To assess the value of preoperative neutrophil-lymphocyte ratio ( NLR) for predict the prognosis in patients with high grade T1 bladder.Methods From January 2004 to December 2014, the data of 307 patients diagnosed as bladder cancer of Stage 1 and high grade after undergoing TURBT were analyzed, including gender, age, smoking status, tumor number and size, hydronephrosis, intravesical instillations and preoperative blood transfusion of 307 patients diagnosed as bladder cancer of stage 1 and high grade after undergoing TURBT were analyzed retrospectively.All patients were primary urothelial carcinoma.According to preoperative NLR,patients were divided into the low NLR group( NLR≤2.42,n=197) and the high NLR group(NLR >2.42,n =110).Recurrence-free survival (RFS) and progression-free survival ( PFS) were calculated according to the Kaplan-Meier model and compared by the log-rank model.Cox regression models were used for multivariate analyses of the association between NLR and bladder cancer, then the prognostic factors affecting RFS and PFS were evaluated.Result of these 307 patients, the low NLR group accounted for 64.2%(197/307), and the high NLR group accounted for 35. 8%(110/307).The mean follow-up period was 71(range, 1-123)months.The recurrence rate in the low NLR group and the high NLR group recurrence rate were 19.2%( 38/197 ) and 34.5%( 38/110 ) respectively, RFS were 73.0(range, 2-123)months and 67.5(range, 1-122)months respectively.The progression rates were 4.1%(8/197) and 10.9%(12/110) respectively.The recurrence and progression rates in the high NLR group is higher than those in the low NLR group(P2.42(P=0.007,HR=1.912)and hydronephrosis (P<0.01, HR =2.485 ) are associated with higher risk of recurrence.Conclusion Elevated preoperative NLR is an independent predictor of RFS and PFS in patients with high grade T1 bladder cancer.
ABSTRACT
Aromatase is a key enzyme responsible for in vivo estrogen biosynthesis. Inhibition of the activity of the aromatase has become an alterative way for treatment of breast cancer. In this review, the structure and catalytic mechanism of the aromatase is briefly introduced followed by thorough review of the progress in the study of the steroidal and non-steroidal aromatase inhibitors. This review is focused on the natural compounds that exhibit the aromatase inhibition, which include flavonoids, xanthones, coumarins, and sesquiterpenes. The structure-activity relationship of these compounds is also discussed.
ABSTRACT
Objective To observe the fixation features of foveoschisis in pathological myopia patients.Methods 36 patients(42 eyes)with>-6.00D myopic degree and foveoschisis who diagnosed by optical coherence tomography were included.The patients were divided into foveoschisis with retinal detachment group(11 eyes),foveoschisis with macular hole group(12 eyes)and only foveoschisis group(19 eyes).Micro-perimeter MP-1 was used to identify the fixation location and fixation stability.Results The eccentric fixation were formed above the foyea in the foveoschisis with retinal detachment and foveoschisis with macular hole group,the fixation location was formed on fovea in the only foveoschisis group.The fixation stability of the foveoschisis with retinal detachment,foveoschisis with macular hole and only foveoschisis group were(23±4)0A,(59±6)% ,(91±11)% respectively,the difference was statistically significant(F=243.47,P＜0.01).Conclusions The fixation location is formed on foyea in the patients with foveoschisis in pathological myopia.The eccentric fixation is formed above the fovea in the patients who has foveoschisis with retinal detachment and macular hole in pathological myopia.
ABSTRACT
OBJECTIVE To observe the bacterial content on the suspension bed sheet in burns intensive care unit.METHODS To detect the bacterial content on the suspension bed sheet and the common sickbed sheet(20 sheets in each group) after sampling them before use and 12 and 24 hours after use and to compare them.RESULTS The bacterial content on two sorts of the sheets before use was accorded with the Ministry of Health standards.but 12 hours after use the significant bacterial content on the common sickbed sheet [(4.9?2.1) CFU/cm2] was much higher than that on the suspension bed [(3.2?1.1) CFU/cm2,P0.01].CONCLUSIONS Using suspension bed could reduce bacterial content on the sheet and ease nurse workload.
