Objective To evaluate the different penile prosthesis for the management of erectile dysfunction. Methods Of the 548 cases,melleable prosthesis has been implanted in 228(41.6%),one piece inflatable prosthesis(Dynaflex) in 45 (8.2%),two piece inflatable prosthesis (Mentor) in 2 and three piece inflatable prosthesis in (AMS 700 CXM) 273 (50.2%). Results The overall complication rate has been 5.1%(28/548),nonmechanical in 8 (1.5%) and mechanical complication in 20 (3.6%). The mechanical complication rate of AMS malleable 600 and AMS 700 CXM were 1.3% (3/228) and 5.5% (15/273) respectively.The cylinder leakage of AMS 700 CXM was 3.7% (10/273). Conclusions The mechanical function and concealment have been significantly improved with AMS 700 CXM whereas improvement of the cylinder quality is yet needed.

Objective To explore the role of IL-1β in inhalation injury repairment through its effects on the expression of prostaglandin E_2 in cultured airway fibroblasts of mouse. Methods The cultured airway fibroblasts in vivo from male Kunming species mouse were randomly divided into control group and treatment group. The superna-rant and cells were collected at different time after treated with IL-1β. The expressions of PGE_2, COX-2 and mPGES1 protein in supernatant and cells were measured by ELISA and Western Blot. Results ①PGE_2 levels in the cultured airway fibroblast supematant at 8 h(148.2±28.3) ng/L,16 h(267.6±45.4)ng/L,24 h(210.5±38.6) ng/L and 48 h(198.7±36.5) ng/L were higher than that in the control group (P < 0.01), and peaked at 16 h;COX-2 ex-pressions at 8 h(0.478±0.029) COX-2/β-actin, 16 h(0.672±0.047) COX-2/β-actin,24 h(0.617±0.036) COX-2/β-antin, and 48 h (0.593±0.034) COX-2/β-actin were higher than that in control group (P < 0.01), and peaked at 16 h;mPGES1 at 8 h(0.300±0.018) mPGES1/β-actin, 16 h(0.549±0.034) mPGES1/β-actin, 24 h (0.497±0.030)mPGES1/β-actin and 48 h(0.443±0.026)mPGES1/β-actin were higher than that in the control group(P < 0.01), and peaked at 16 h. ②PGE_2 in 0.1 μg/L IL-1β group (142.9±2.3) ng/L, 1.0 μg/L IL-1β group (267.6±45.4) ng/L and 10.0 μg/L IL-1β group (587.3±106.9) ng/L were higher than those in the control group (58.5±16.0) ng/L (P < 0.01), and there was significant difference among the three groups (P < 0.01);COX-2 in 0.1 μg/L IL-1β group(0.525±0.031) COX-2/β-actin, 1.0 μg/L IL-1β group(0.672±0.047) COX-2/ β-actin and 10.0 μg/L IL-1β group(1.012±0.064)COX-2/β-actin were higher than that in the control group (0.309±0.019) COX-2/β-actin (P < 0.01), and there was difference among the three groups (P < 0.01);mPG-ES1 in 0.1 μg/L IL-1β group(0.380±0.021) mPGES1/β-actin, 1.0 μg/L IL-1β group (0.549±0.034) mPG-ES1/β-actin, and 10.0 μg/L IL-1β group(0.879±0.045) mPGES1/β-actin were higher than those in the control group(0.199±0.012)(P<0.01),and there was difference among the three groups(P<0.01).Conclusions IL-1β may upregulate PGE_2, COX-2 and mPGES1 expressions in airway fibroblast, indicating that IL-1β influences PGE_2 synthesis through COX-2 and mPGES1 expression and participates in airway inhalation injury course. Airway fibroblasts may be a main source cell of inflammatory mediators in injury repair.

Objective To compare several histopathological staining methods in demonstrating Cryptococcus neoforman.Methods Hematoxylin-eosin(HE) method,periodic acid-Schiff(PAS) method,Alcian blue method and Grocott-Gomori's methenamine silver method were carried out in the lung and brain tissue samples from 7 autoptical cases identified with Cryptococcus neoforman infection.Results All these methods demonstrated Cryptococcus neoforman infection,HE method showed unclear pink cell body which were difficult to be found.Alcian blue method displayed blue picture,and PAS method showed violet-red body,and Grocott-Gomori's methenamine silver method presented clear dark black picture which was easy to be distinguished from other components.Conclusion Grocott-Gomori's methenamine silver method is the best method in staining Cryptococcus neoforman.

With the development of brain research, study of neural coding has attracted more attention. Neural coding by informatics entropy is a very important aspect in the research field. This paper presents an overview of typical entropy coding methods of neuronal spike train including binary string method, direct method, asymptotically unbiased estimator method, inter-spike interval and mutual information method. Related principles and application are reviwed.

Kawasaki disease is a systemic inflammatory disease of small and medium vessels in children under 5 years of age, which is also one of the most common causes of acquired heart disease in children.Stem cells are a kind of multipotential cells with the ability of self-renewal, self-replication and multi-differentiation.They are important biomaterials in modern regenerative medicine and tissue engineering.So far, substantial studies have found that stem cells such as endothelial progenitor cells, induced multifunctional stem cells, adipose-derived stem cells and so on are involved in the regulation of the pathogenesis of Kawasaki disease and play an important role in anti-inflammation and protection of the vascular endothelial cell damage.The potential of stem cells is gradually being developed and applied to the diagnosis and treatment of Kawasaki disease.However, the pathogenesis and treatment of stem cells in Kawasaki disease are not fully understood, and more basic and clinical trials are still needed.
