BACKGROUND:The poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold which has been constructed in previous experiments has good biocompatibility and biodegradability and generates non-toxic degradation products.
OBJECTIVE:To observe the vascularization of rabbit renal microvascular endothelial cels co-cultured with poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold.
METHODS:The poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold having a three-layer structure (layer of bone/bone and cartilage interface layer/layer of cartilage) was prepared by solvent casting/particle leaching method. The renal microvascular endothelial cels at passage 3 were seeded onto the scaffold of bone layer. The proliferation of the renal microvascular endothelial cels growing on the scaffolds was examined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method, the growth of cels in the scaffold was observed by hematoxylin-eosin staining under electron microscope after 10 days.
RESULTS AND CONCLUSION:The integrated osteochondral scaffold had a clear appearance of three-layer structure, which had closed connections between the three layers. Porous bone layer was visible as wel as uniform and interlinked pores, and the porosity was 78%. The renal microvascular endothelial cels seeded onto the scaffold proliferated wel and presented a three-dimensional growth after 10 days of co-culture, but there were no cels on the interface layer. Cels which adhered and grew between the pores of the bone layer were observed through hematoxylin-eosin staining. Cels showed a luminal-like structure growing on the scaffold with the porous structure, but they did not grow into the interface layer of bone and cartilage.

AIM: To analyze the characteristics of neurological ophthalmology manifestation of patients with neurosyphilis. · METHODS: Retrospective and nonrandomized case analysis were used. Totally 22 cases of 39 eyes were included. They were 17 males and 5 females, aged from 34 to 65 years old. The average age were 49. 6 years old. ·RESULTS: The optic nerve atrophy presented in 11 cases of 22 eyes. One eye of them accompanied by left eye oculomotor nerve palsy;5 eyes in 3 cases expressed as optic neuritis acute phase;neuroretinitis appeared in 4 cases of 6 eyes; 1 case of 2 eyes expressed as chorioretinitis accompanied by optic disc edema; central retinal artery occlusion were found in 1 case of 1 eye. Argyll-Robertson pupil was as only manifestation in 2 cases of 3 eyes. In all cases, Argyll-Robertson pupil signs can be seen in 19 eyes. Treponema pallidum particle agglutination test ( TPPA) were positive in all 22 cases. Syphilis rapid plasma reactin test ( RPR ) were positive in 19 of 21 cases. All patients underwent lumbar puncture and cerebrospinal fluid were detected for RPR, cerebrospinal fluid protein, white blood cell count. Cerebrospinal fluid RPR were positive in 13 cases. Cerebrospinal fluid protein were greater than 450mg/L in 18 cases. Cerebrospinal fluid white blood cell count were greater than 5/mm3 in 13 cases. · CONCLUSION: Neurosyphilis involving neuro -ophthalmology often occurs in middle-aged men and subacute onset. Both eyes can suffered from optic nerve disease simultaneously or sequencely. A few can be expressed as other cranial nerve palsy, which may lead to misdiagnosis. Considering medical history, clinical manifestations, ophthalmic examination, serum and cerebrospinal fluid laboratory tests can improve the diagnostic rate.

Objective To explore the effect of the JAK/STAT signal pathway on the apoptosis-related gene in the synovial tissue of rat rheumatoid arthritis (RA).Methods Fifty rat models of collagen-induced arthritis,whose arthritis index was more than 2,were divided into the model group,the low dose of AG490 group,the medium dose of AG490 group and the high dose of AG490 group.In addition,6 rats were treated intraperitoneal injection.Then,the arthritis index and the change of apoptosis-related genes were compared.Multiple-sample average was analyzed by single-factor x2 test and LSD-t or Tamhane's T 2 test were used for two-two comparison.Results The arthritis index of the model group increased evidently,and the apoptosis inhibitor Bcl-2,Bcl-xl gene and protein expression was up-regulated,which was significantly different when compared with that of the control group(0.931±0.035 vs 0.351±0.024,0.920±0.037 vs 0.271±0.029,0.322±0.047 vs 0.230±0.031 ).The expression of apoptosis promoting factor Bax wasslightly up-regulated.The blockage of JAK/STAT pathway cotld down-regulate the expression levels of the gene and protein of survivins Bcl-2 and Bcl-xl,and up-regulate the gene and protein expressions of Bax.Conclusion In the process of RA development,apoptosis inhibitor Bcl-2,Bcl-xl gene and protein expression is up-regulated.JAK/STAT signal transduction pathway regulates the apoptosis process.
