Prostate cancer incidentally discovered at the time of radical cystoprostatectomy does not decrease overall survival: Results from a large Chinese medical center

ABSTRACT Purpose To investigate the incidence and pathologic characteristics of prostate cancer (PCa) incidentally discovered at the time of radical cystectomy and its impact on overall survival. Materials and Methods A single center retrospective study of 762 male patients who underwent radical cystoprostatectomy from Jan 1994 to Dec 2012. Results Of all included patients, 132 (17.3%) were found to have PCa. Patients with incidental PCa had a significantly higher mean age (69.2 vs. 62.2 years, P=0.015). Among the 132 patients with PCa, prostate specific antigen (PSA) analysis was available in 76 patients (57.6%), with a median value of 1.06ng/mL, and 61 (80.3%) patients had a PSA value below 4ng/mL. Four hundred and thirty-six patients (57.1%) were successfully followed, with a median duration of 46.5 months. The overall 5-year survival rate was 62.1%, and the 5-year cancer-specific survival rate was 72%. PCa recurrence was defined by two consecutive PSA values of >0.2 ng/mL and rising, and no PCa recurrence occurred. According to a univariate analyses, incidental PCa was not associated with cancer-specific survival (P=0.192) or overall survival (P=0.493). According to univariate analyses, the overall survival of patients with PCa was not associated with prostate cancer staging, PSA value, or Gleason score (All P values>0.05). Conclusions Prostate cancer incidentally discovered at the time of radical cystectomy does not decrease overall survival. Patients with incidental PCa were older than those without. The PSA value before operation is not helpful for predicting incidental prostate cancers.

Dynamic change of four triterpenic acids contents in different organs of loquat (Eriobotrya japonica) and phenology / 中国中药杂志

The loquat is widely cultivated in China, its succulent fruits, leaves and flower are used as a traditional medicine for the treatment of many diseases. The study is aimed to analyse the content of the four triterpene compounds ( ursolic acid, corosolic acid, maslinic acid, oleanolic acid) in different organs, and investigate the dynamic changes in different phenological period. The triterpenic acids content in the samples was measured by HPLC based on the plant phenological observations. The results showed that order of four triterpenic acids content in different organs from high to low was defoliation (23.2 mg x g(-1)) > mature leaves (21.7 mg x g(-1)) > young leaves (17.5 mg x g(-1)) > fruits (7.36 mg x g(-1)) > flowers (6.40 mg x g(-1)). The triterpenic acids were not detected in the seeds. The total amount of the four triterpenic acids in the loquat leaves collected in the different phenological stages of sprout, flower bud, blossom and fruit varied between 17.8 and 26.2 mg x g(-1) (defoliation), 16.5 and 23.5 mg x g(-1) (mature leaves), 14.7 and 21.5 mg x g(-1) (young leaves), respectively. The content increased progressively with the leaf development, maturation and aging. There was a higher level of the dry material and triterpenic acids accumulation in the mature leaves during fruit enlargement. This paper attempts to present the case for medicinal plants of a broad geographical distribution to study on the secondary metabolites and harvesting time.

Plasmacytoid urothelial carcinoma of the bladder.

Plasmacytoid urothelial carcinoma (PUC) of the urinary bladder is an uncommon and aggressive variant of urothelial carcinoma associated with late presentation and poor prognosis. Immunohistochemical examination showing expression of epithelial markers, CD138, and losing the membranous expression of E-cadherin confi rms evidence of PUC. Here, we report a case of bladder PUC of a 74-year-old male who presented with hematuria. A transurethral biopsy revealed urothelial carcinoma with plasmacytoid appearance. The diagnostic dilemmas of this unusual variant of urothelial malignancy and its clinical impact are discussed. The pathological diagnosis was PUC (High-grade, pT4N2M0) with diffuse muscle, small tracts, and vascular invasion, in which almost of the areas studied on the tissue section showed Plasmacytoid differentiation.

Prevalence and distribution of metabolic syndrome in a southern Chinese population Relation to exercise, smoking, and educational level

To investigate the prevalence and distribution of metabolic syndrome [MetS] and the impact of exercise, smoking, and educational level on the risk of MetS in a southern Chinese population. A cross-sectional study was conducted in Zhuhai City, China from June to August 2012. Data on exercise, smoking, and educational level, anthropometric parameters, blood pressure, lipid, and glucose levels were collected. The prevalence of MetS [as defined by the International Diabetes Federation] was determined. Data necessary to evaluate MetS, the socio-economic characteristics, and lifestyle were obtained for 4645 subjects aged 18-75 years old. A total of 19.8% of the participants had MetS. The adjusted odds of having MetS were lower among males [adjusted odds: 0.75; 95% confidence interval [CI]: 0.57-1.01] compared with females. Those participants who currently smoked had a higher risk of developing MetS compared with non-smokers [adjusted odds: 1.61; 95% CI: 1.13-2.50]. Those who had no physical exercise had a higher risk of developing MetS compared with those who physically exercised more than 60 minutes/day [adjusted odds: 1.51; 95% CI: 1.12-2.23;]. Compared with those with no education, every category of attained educational level had a lower risk of developing MetS [P<0.001]. The findings in this study revealed that current smokers had a greater risk of developing MetS compared with non-smokers. Increased physical activity and higher levels of education attained served as protective factors for the population

Prevalence of chronic kidney disease and prediabetes and associated risk factors: a community-based screening in Zhuhai, Southern China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The prevalence of chronic kidney disease (CKD) and prediabetes has increased in China, and at different rates in different locations. Therefore a community-based screening research was conducted in order to determine the prevalence of CKD and prediabetes, and to analyze associated risk factors of CKD and prediabetes in a city of Southern China.</p><p><b>METHODS</b>A total of 7801 community residents aged 18 year and older from 6 communities were screened by a stratified random cluster sampling method. An estimated glomerular filtration rate (eGFR), albuminuria, fasting plasma glucose (FPG), and homeostatic model assessment of insulin resistance (HOMA-IR) were measured. Age-standardized prevalence was calculated by the direct method with the use of data on the population distribution in China in 2006. Multivariate logistic analysis was used to analyze the risk factors of CKD and prediabetes, and association of insulin resistance (IR) with CKD and prediabetes was analyzed.</p><p><b>RESULTS</b>The age-standardized prevalence of CKD was 12.5%, eGFR < 60 ml×min(-1)×1.73 m(-2) was 2.7% and ACR (albumin to creatinine ratio) > 30 mg/g was 10.3%. The age-standardized prevalence of prediabetes was 12.1%. Logistic regression suggests that IR was a common independent risk factor of CKD and prediabetes. Further analysis show that HOMA-IR was increased with the aggravation of kidney injury and FPG.</p><p><b>CONCLUSION</b>CKD and prediabetes have become a major public health problem in Zhuhai, Southern China; insulin resistance may be an important risk factor.</p>

MMP-2 expression tended to decrease, while TIMP-1 and serum creatinine increased with the pathological grades of IF/TA (P<0.05). In IF/TA group, the expression of TIMP-1 was positively correlated to serum creatinine level (r=0.718, P=0.00<0.05).</p><p><b>CONCLUSION</b>Abnormal expressions of MMP-2 and TIMP-1 can promote the development of renal fibrosis in chronic ABMR.</p>

Mini-percutaneous nephrolithotomy in the treatment of un-hydronephrotic cata-staghorn renal calculi / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the surgical techniques and clinical effects of mini-percutaneous nephrolithotomy (mini-PCNL) in the treatment of un-hydronephrotic cata-staghorn renal calculi.@*METHODS@#The clinical data of 46 cases (31 males and 15 females) treated by mini-PCNL were retrospectively analyzed. There were mono-renal calculi in 38 patients (3 patients were the isolated renal calculi) while the other 8 combined opposite side upper urinary tract calculi. The diameter of calculi ranged from 4.2 to 6.4 (mean=5.2) cm. Puncturation was guided by B-type ultrasound. Lithotripsy by air pressure path lithotripter and/or holmium laser was done when the pervium was established.@*RESULTS@#The pervium in the 46 patients was successfully established by one-session puncturation with B-type ultrasonography guidance. The operative time ranged from 140 to 280 (mean=190) min. The amount of blood ranged from 50 to 200 (mean=100) mL and no one needed blood transfusion. Calculus was completely removed in 18 patients (39.1%). Calculi in 10 patients (21.7%) were completely removed among the 20 patients who underwent second-look mini-PCNL. Calculi in 1 of the 3 cases were completely removed by third-look mini-PCNL. Left-over calculi in 17 patients (8 patients after the first time mini-PCNL, 7 patients after second-look, and 2 patients after third-look) were treated by extracorporeal shock-wave lithotripsy (ESWL) and 8 were removed completely. All the 46 patients were followed up for 4 to 48 months. None of them had nephro-hydrops or stenosis. Renal function re-investigation showed that 8 patients recovered and 2 improved in the 10 patients who had azotemia before. Two (5.4%, 2/37) had calculus recurrence in 37 cases which calculi were completely removed before. The size and amount of left-over calculi in 3 patients (33.3%, 3/9) were increasing.@*CONCLUSION@#Mini-PCNL is effective and causes less trauma for un-hydronephrotic cata-staghorn renal calculi. Mini-PCNL combined ESWL may substitute the open operation and is the preferred method for un-hydronephrotic renal cata-staghorn calculi.

Effect of low-dose FK778 on the progression of chronic renal ailograft rejection in a rat model / 中华器官移植杂志

Objective To study the effect of low-dose FK778 in preventing chronic renal al- lograft rejection in rats.Methods The rat model of chronic renal allograft rejection was established by using micro-surgery technique.The recipients were divided into two groups.The recipients in the study group were treated with FK778 at a dose of 5mg?kg~(-1)?d~(-1)dissolved in carboxymethylcellulose by means of gavage and the controls were treated with carboxymethylcellulose.Urinary protein con- centrations were measured every 4 weeks for 24 weeks.On 24th week after operation,the rats were killed and the kidney grafts were taken out for histological and immunohistological examinations as well as quantitative real-time RT-PCR analysis.Results After 24 weeks of treatment,proteinuria, the severity of chronic rejection,glomeruIosclerosicytes and monocytes/macrophages in the study group were significantly milder than in control group.And the expression of TGF-?mRNA and PDGF-B mRNA was significantly reduced in the study group as compared with that in the control group.Conclusion Low-dose of FK778 might prevent the rats from chronic renal allograft rejection.

Treatment of renal calculi with percutaneous nephrolithotomy / 中华泌尿外科杂志

Objective To evaluate the feasibility and efficacy of percutaneous nephrolithotomy (PCNL)in treating renal calculi.Methods The data of 118 patients with renal calculi who had underg- one PCNL from July 2002 to August 2004 were retrospectively analyzed.There were 86 men and 32 women. The mean age was 39 years(range,7-68 years).Of the 118 cases,11 had pelvic calculi,16 had calyx cal- culi,35 had pelvocalyceal calculi,54 had staghorn calculi,and 2 had bilateral renal calculi.The mean stone size was 2.5 cm?1.5cm(ranged from 2.0 cm?1.0 cm to 4.5cm?4.0cm).Results Of the 118 ca- ses,112 underwent one-stage PCNL,and 6,two-stage PCNL.The procedure was performed by single tract in 114 cases,and by two tracts in 4 cases.Lithotomy was done by one session in 60 cases,by 2 sessions in 42 cases,and by 3 sessions in 16 cases.The total stone clearance rate was 81.4%.The mean operative time was 120 min,and mean hospital stay was 15 d.No blood transfusion was needed during operation,and only one patient experienced bleeding(about 500 ml)after 4 d postoperatively,and was cured by conservative treat- ment such as blood transfusion and anti-inflammation.No major complications were observed in other pa- tients.Conclusions PCNL has advantages of minimal trauma,less blood loss,fewer complications,and is safe and effective in treating renal calculi,especially for patients who will have the second procedure.
