Objective To investigate the morphological changes of peritoneum during peritoneal dialysis (PD) and elucidate the possible mechanism of its functional deterioration. Methods Peritoneal biopsies were obtained from normal subjects( n = 10), uremic predialysis patients( n = 12) at catheter insertion and PD patients ( n = 10) at the time of catheter remove or reinsertion or renal transplantation, peritoneal morphology was studied by light microscopy, scanning electron microscopy and transmission electron microscopy. Results Normal peritoneal membrane consisted of a monolayer of mesothelial cells on a basement membrane, and a layer of connective tissue containing cells, blood vessels, lymphatic vessels and so on. Mesothelial cells were polygonal, often elongated, and had numerous microvilli on their luminal surface. Sometimes the microvilli ended with roundish formation or resembled a corona. There were lots of oval or roundish pinocytotic vesicles in the cytoplasm of mesothelial cell. Submesothelial connective tissue contained many collagen and elastic fibers. The peritoneal morphology of uremic predialysis patients was similar to that of normal subjects. But significant abnormalities of peritoneal morphology were observed in PD patients and the changes were progressive. Microvilli were the first site of damage, including microvilli shortening, gradual reduction in number and following total disappearance. Then mesolhelial cell detachment from basement membrane and total disappearances were found. Finally the peritoneal membrane only consisted of submesothelial connective tissue denudation of cells. Conclusions PD can modify peritoneal morphology and structure. The morphological change is progressive and might be one of the important causes of peritoneal failure. Peritoneal biopsy can provide lots of valuable informations about the impact of PD, and thus further study on the relationship between peritoneal structure and its function is very useful for understanding of the physiopathology of peritoneum during PD.

Objective To improve the theoretical basis for the typical hemodynamic changes in subclavian steal syndrome (SSS) patients underwent transcranial doppler (TCD) by detailed hemodynamic analysis.Methods Patients with SSS were examined by transcranial doppler and some patients performed tourniquet test.Flow spectrum,flow velocity and pulsatility index (PI) of vertebral artery,basilar artery and middle cerebral artery (MCA) were recorded.Results The flow spectrum of steal side vertebral artery showed that there were 14 cases with systolic notch,18 cases with systolic reverse flow and 3 cases with flow completely reversed.The flow spectrum showed high resistance spectrum in vertebral artery and basilar artery and ipsilateral basilar artery vortex or turbulence in 32 cases.The PI value was higher in contralateral vertebral artery and basilar artery than in anterior circulation (q =9.56,9.98,both P < 0.01),and there was no difference between contralateral vertebral artery and basilar artery (q=0.416,P>0.05).The tourniquet test were positive in all 22 patients.Conclusions TCD is a convenient,fast,accurate and non-invasive method for hemodynamic examination,which is the first choice for the diagnosis of SSS.

Lactate and succinate were produced by Corynebacterium acetoacidophilum from glucose under oxygen deprivation conditions. To construct knockout mutant, lactate dehydrogenase gene (ldh) of C. acetoacidophilum was deleted by double-crossover chromosome replacement with sacB gene. Comparing with the wild strain ATCC13870, ldhA-deficent mutant produced no lactate with glucose consumption rate decreased by 29.3%, while succinate and acetate concentrations were increased by 45.6% and 182%, respectively. Moreover, the NADH/NAD+ rate was less than 1 (about 0.7), and the activities of phosphoenolpyruvate carboxylase and acetate kinase of the ldhA-deficent mutant were enhanced by 84% and 12 times, respectively. Our studies show that succinicate and acetate production pathways are strengthened by blocking lactate synthesis. It also suggests that improving NADH supply and eliminating acetate generation are alternative strategies to get high succinate-producer.

Objective: To study the effect of hyperplasia suppressor gene (HSG) in inducing vascular smooth muscle cell apoptosis and the underlying mechanisms. Methods: The cultured VSMCs were transfected with an adenoviral vector containing rat HSG gene. Effects of HSG on VSMC apoptosis were investigated by fluorescent dye staining to detect the tact of nuclei, and by flow cytometry to define the content of DNA and to detect the levels of caspase-3. The expressions of Bcl-2 and Bax were also performed by Western blot analysis. Results: The increased expression of HSG in VSMCs infected with AdHSG induced apoptotic cell death detected by flow cytometry assay and nucleic staining. Compared with control groups, HSG induced vascular smooth muscle cell apoptosis 72 h after infected with adenoviral vector (39.6%?3.2% vs. 2.6%?0.9%,P

Objective To compare the perioperative outcomes and short-term efficacy of three-port extraperitoneal laparoscopic radical prostatectomy (ELRP) and four-port ELRP.Methods Two hundred patients who had undergone ELRP for prostate cancer by a single surgeon from November 2010 to October 2014 were retrospectively analyzed.Among them,95 cases underwent three-port ELRP and 105 cases underwent four-port ELRP.On the basis of traditional four-port ELRP,three-port ELRP was characterized by the omission of the trocar on the inner side of right anterior superior iliac spine.The mean age was 66.8 ± 15.5 years,and mean total prostate specific antigen (tPSA) was 15.3 ± 12.4 μg/L.There were no significant differences including age,body mass index,tPSA,clinical stages,acceptance of neoadjuvant hormone therapy,history of transurethral resection of the prostate,history of diabetes mellitus between the 2 groups (P > 0.05).Patients in three-port ELRP group had significantly smaller prostate volume than fourport group (35.6 ± 16.7 ml versus 42.2 ± 24.7 ml,P < 0.05).The clinical factors as operative time,estimated blood loss,hospital stay,drainage tube keeping days,pathological Gleason scores,pathological stages,positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates were compared between the 2 groups.Results The three-port group had significantly shorter operative time than the four-port group (81.0 ± 18.6 min versus 103.6 ±34.6 min),less estimated blood loss (102.6 ±75.8 ml versus 217.5 ± 182.9 ml),less positive surgical margin rates (13.7% versus 27.6%).There were 9 patients having Gleason scores more than 7 in the three-port ELRP group and 29 patients in four-port ELRP group (P < 0.05).There were no significant differences of hospital stay,drainage tube keeping days,pathological stages between the 2 groups (P > 0.05).Eighty-three cases in the three-port ELRP group (87.4%) were followed up for 5-19 months with the median time of 11 months.Ninety-two cases in fourport ELRP group (87.6%) were followed up for 17-52 months and the median time was 27 months.There were no significant differences of biochemical recurrence rates and urinary incontinence rates between the 2 groups(P > 0.05).Conclusions Compared to four-port ELRP,three-port ELRP can provide shorter operative time,less blood loss,better negative surgical margin rates,similar oncological control and recovery of postoperative continence.In experienced hands,three-port ELRP could be a feasible and effective option for localized prostate cancer.
