Abdominal multivisceral transplantation is a new and proved effective therapeutic methods for two or more terminal abdominal organs. Upper abdominal exenteration(resection of the liver,stomach,spleen,pancreaticoduodenal complex,and part of the colon) for the treatment of otherwise unresectable tumors is one of the more radical operations in oncology.Some new surgical methods such as liver-intestinal,liver-kidney,pancreas-kidney and multivisceral cluster transplantation have emerged recently.These new advance surgical approache improve the curative effect of abdominal organ transplantation.

OBJECTIVETo investigate the inhibitory effect of bone marrow mesenchymal stem cells (BMSCs) on E coliinduced prostatitis in rats.

METHODSBMSCs were isolated, cultured and amplified by the attached choice method. Fifty SD rats were randomized into five groups of equal number: normal control, acute bacterial prostatitis (ABP) , chronic bacterial prostatitis (CBP), ABP + BMSCs, and CBP + BMSCs, and the animals in the latter four groups were injected with E. coli into both sides of the prostate under ultrasound guidance for 1 - 14 days to induce ABP and for 4 - 12 weeks to induce CBP. The control rats were injected with the same amount of PBS. Two weeks after injection of BMSCs into the prostates, pathomorphological changes in the prostate were observed under the light microscope and the mRNA and protein levels of IL-1β and TNF-α determined by RT-PCR and ELISA, respectively, followed by statistical analysis with SPSS 18.0.

RESULTSHistopathological evaluation showed typical pathological inflammatory changes in the prostates of the rats in the ABP and CBP groups, including glandular structural changes, interstitial edema, inflammatory cell infiltration, and fibrous hyperplasia, which were all remarkably relieved after treated with BMSCs. The mRNA and protein levels of IL-β ([0.829 ± 0.121] and [271.75 ± 90.59] pg/ml) and TNF-α ([0.913 ± 0. 094] and [105.78 ± 19. 05] pg/ml) in the ABP and those of IL-1β ([0. 975 ± 0. 114] and [265. 31 ± 71. 34] pg/ml) and TNF-α ([0. 886 ± 0. 084] and [107. 45 ± 26. 11 ] pg/ml) in the CBP groups were significantly higher than those in the control rats ([0. 342 ± 0.087] and [45.76 17. 99] pg/ml, P <0. 05); ([0.247 ± 0.054] and ([19.42 ± 7. 75] pg/ml, P <0. 01) as well as than those in the ABP + BMSCs ([0. 433 ± 0. 072] and [51. 34 ± 22. 13] pg/ml, P < 0. 05 ) ; ( [0. 313 ± 0. 076] and [28. 38 ± 8. 78] pg/ml, P < 0. 01) and the CBP + BMSCs group ([0.396 ± 0.064] and [56.37 ± 21.22] pg/ml, P <0.05); ([0.417 ± 0.068] and [29.21 ± 10.22] pg/ml, P <0.01).

CONCLUSIONInjection of BMSCs can reduce E coli-induced prostatic inflammation reaction, which.may be associated with its reduction of inflammatory cell infiltration and the expressions of IL-1β and TNF-α in the prostate tissue.

Objective To investigate the illness-related stigma in outpatients with chronic viral hepatitis B and C and its effects on interaction anxiousness and general self-efficacy.Methods Forty-eight patients with chronic hepatitis B ( CHB),41 patients with chronic hepatitis C (CHC) and 29 healthy volunteers were enrolled.Hepatitis-related Stigma Questionnaire (HRSQ) produced by researchers was used to assess stigma in patients of both CHB and CHC.All patients and healthy volunteers were evaluated by Interaction Anxiousness Scale (IAS),General Self-efficacy Scale (GSES) and Simplified Coping Style Questionnaire (SCSQ).Results Hepatitis-related stigma was common in both CHB and CHC.The most common positive items and their percentages of CHB and CHC were rejection in job seeking (81.2％,75.6％ ), keeping conditions about hepatitis secret (72.9％,75.6％ ),feeling discrimination in society (66.7％,56.1％ ) and rejection in mate selection (60.4％,61.0％ ),and the rarest ones and percentages were feeling lowest stress together with patients with the same disease (35.4％,31.7％ ) and being understood only by patients with the same disease (33.3％,26.8％ ).Differences of positive percentages of any items between CHB and CHC were not statistically significant (P ＞0.05 ).One-way ANOVA showed that difference of IAS scores among three groups of participants was not statistically significant ;and GSES score of CHB(2.41 ± 0.45 )was not statistically different from that of CHC (2.49 ±0.60 ),but they both were lower than that of healthy control (2.78 ± 0.52) (F=4.648,P =0.011 ).The multivariate stepwise regression analysis showed that the item feeling much different from others of HRSQ entered the formula of CHB IAS score (B =4.861,adjustment R2 =0.106),and the item being understood only by patients with the same disease of HRSQ entered the formula of CHC IAS score (B =6.745,adjustment R2 =0.113);negative coping dimension score of SCSQ ( B =- 0.424),the item feeling discrimination in society ( B =-0.359) and feeling lowest stress together with patients with the same disease ( B =-0.274) entered the formula of CHB GSES score (adjustment R2 =0.280).Conclusion Illness-related stigma is common in outpatients with chronic viral hepatitis,which probably raises patients' interaction anxiousness and weakens the general selfefficacy of patients with hepatitis B and C.

The corneal transparency is one of the important basic conditions for realizing normal physiological functions of visual organs. Also corneal endothelial cells are important conditions for maintaining normal corneal transparency. Therefore, only to ensure the morphology and physiological integrity of the corneal endothelial, can have normal vision. However, intraocular surgeries inevitably cause damage to corneal endothelial cells. This paper will review the effects of glaucoma surgery on corneal endothelial cells.

OBJECTIVETo culture rat prostate glandular epithelial cells and study their barrier functions in vitro.

METHODSRat prostate glandular epithelial cells were cultured in vitro. The expression of the tight junction protein claudin-1 was determined by immunohistochemistry, the structure and composition of the epithelial cells observed under the inverted microscope and transmission electron microscope. The transepithelial electrical resistances (TEERs) were monitored with the Millicell system. The permeability of the prostate glandular epithelial cells was assessed by the phenol red leakage test.

RESULTSCompact monolayer cell structures were formed in the prostate glandular epithelial cells cultured in vitro. Immunohistochemistry showed the expression of the tight junction protein claudin-1 and transmission electron microscopy confirmed the formation of tight junctions between the adjacent glandular epithelial cells. The TEERs in the cultured prostate glandular epithelial cells reached the peak of about (201.3 ± 3.5) Ω/cm2 on the 8th day. The phenol red leakage test manifested a decreased permeability of the cell layers with the increase of TEERs.

CONCLUSIONThe structure and function of rat prostate glandular epithelial cells are similar to those of brain capillary endothelial cells, retinal capillary endothelial cells, and intestinal epithelial cells. In vitro cultured prostate glandular epithelial cells have the barrier function and can be used as a model for the study of blood prostate barrier in vitro.
