[Summary] Serum cystatin C levels were measured by microparticle enhanced turbidimetry in 114 type 2diabetic patients without retinopathy (group A) and 105 type 2 diabetic patients with retinopathy (group B),as well as 47 normal healthy individuals as controls (group NC).The results showed that the serum cystatin C level of group B was much higher than those of group NC and group A (P<0.05).However,there was no difference in serum cystatin C level between group NC and group A.Multivariate logistic regression analysis revealed that serum levels of cystatin C and cholesterol,and systemic blood pressure were independent risk factors of diabetic retinopathy in type 2 diabetic patients (all P<0.05),suggesting that detection of serum cystatin C level may play an important role in early diagnosis and prevention of diabetic retinopathy.

AIM: To investigate the effects of prenatal stress (PS) on neurons and neuronal ultrastructure of hippocampus in offspring rats, and to explore the role of the overproduction of oxidants. METHODS: One month male offspring rats were obtained to observe the neuronal number, neuronal ultrastructure and the number of nNOS -positive cell in hippocampus. RESULTS: The neuronal number of CA1 and CA4 subregions in late gestation stress (LS) offspring decreases significantly. The neuronal ultrastructure of CA1 subregion in MS (stress in 7-13 days of gestation) and LS offspring appeared bulgy mitochondria, unclear membrane and irregular electron density. Lipofuscin pigments increased; The number of nNOS-positive cell in CA1, CA2, CA3 subregions and DG of MS group and the whole hippocampus of LS group increased significantly. CONCLUSION: PS damaged the neurons and neuronal ultrastructure of hippocampus of offspring rats. The damages were associated with the overproduction of oxidants.

Objective:To study the isolation, culture and identification of the TMJ cells and to observe the biological characteristics of cultured fibrochondrocytes. Methods:The TMJ discs were dissected from two 1 month goats under sterile conditions and were digested with collagenase. The cells were collected. Morphological changes and attachment efficiency were constantly observed under phase-contrast microscope. Immunohistochemical staining for type I collagen as well as toluidine blue staining were performed. Ultrastructures of the TMJ cells were observed under transmission electron microscope. Results: Most of the primary fibrochondrocytes presented a short spindle-shape while the rest showed polygon-shape. On the 7th day, the perliferating fibrochondrocytes started to contact each other to form a monolayer covering the bottom of the incubation disc. Immunohistochemical staining of type I and toluidine blue staining exhibited positive results. The fibrochondrocytes cytoplasms were rich in mictochondria and endoplasm reticulum. Conclusion: The fibrochondrcytes isolated from one-month-old goat TMJ disc have good proliferation ability in vitro and cells from passage 1 to 3 might be used as seed cells for TMJ disc tissue engineering.
