Retinal vein occlusion ( RVO ) is a common vascular disease of the retina and is one of the main reasons for blindness. ln recent years, there have been some new understanding about the diagnosis and treatment of the disease, especially some new researches about treatment,for example ,in the therapy of the intravitreal injection of triamcinolone acetonide and anti-VEGFs as well as dexamethasone implant ( Ozurdex ) . This article will make a brief summarization of the progress about the diagnosis and treatment of RVO.

BACKGROUND:Bone marrow mesenchymal stem cells have the chemotaxis and homing role that promotes immune system reconstruction, eliminate residual lesions and prevent recurrence in patients.
OBJECTIVE:To observe therapeutic effect of human bone marrow mesenchymal stem cells transplantation into high-metastatic potential hepatocellular carcinoma animal models on metastatic potential of high-metastatic potential hepatocellular carcinoma.
METHODS:Nude mouse models of high-metastatic potential hepatocellular carcinoma were established in vivo. In the experimental group, 5×105 cells were injected via the tail vein on day 7 after tumor inoculation, twice a week. In the control group, cellculture medium, 0.2 mL per mouse, was injected by the tail vein. After the start of the experiment, tumor volume was measured every 4 days. After tumor inoculation for 14 days, 21 days, 28 days, 35 days, 42 days, animal models were sacrificed, and then tumor mass and body mass were recorded to calculate the inhibition rate. PCR was employed to detect osteopontin, bone sialoprotein, and integrinα Ⅴ mRNA expression, as wel as bcl-2, bax, caspase3 mRNA expression.
RESULTS AND CONCLUSION:The inhibition rate of tumor mass showed the best results in week 3. As time went on, the tumor inhibition rate was gradual y decreased. Metastasis-related biological factors showed a gradual down-regulated trend, indicating the polarization of tumor apoptotic indexes, that is, anti-apoptotic factor, bcl-2, showed a decreasing trend, while apoptotic factors, bax and caspase3, appeared to have a gradual y increased trend. These findings suggest that human bone marrow mesenchymal stem cells effects to inhibit high-metastatic potential hepatocellular carcinoma animal models appear to vary with time. After human bone marrow mesenchymal stem cells transplantation for 3 weeks, the inhibition performance on high-metastatic potential hepatocellular carcinoma is the best, and then it weakens with time. Human bone marrow mesenchymal stem cells are found to inhibit the metastatic potential of hepatocellular carcinoma.

BACKGROUND:Animal and cel studies have shown that the Kidney Recipe can prevent and treat osteoporosis and improve bone metabolism, but this recipe is complicated. Recent studies on compound Chinese medicine mainly focused on serum drug metabolism and pharmacokinetics, which has limitations, and the effective ingredient and pharmaceutical material basis are uncertain. OBJECTIVE:In the different concentrations and time, by using different compatibility proportion of active ingredients of Kidney Recipe, osteoblasts from neonatal Sprague-Dawley rats were subjected to culture intervention. The proliferation and differentiation of osteoblasts were determined so as to identify time-effect and dose-effect relationship of Kidney Recipe on osteoblasts and to provide experimental evidences for prevention and treatment of osteoporosis. METHODS:Primary neonatal 24-hour osteoblasts of Sprague-Dawley rats were cultured in vitro. Herbs“tonic”and“cathartic”active chemical components of different proportion were used. The experiment contained three groups:Tonics Medicine (T)>Cathartic Medicine (C) group, TC group and TC group (P<0.05). At mass concentration of 20μg/L, no significant difference was detected in the T>C and TC group (P<0.05), and the proliferation became weak at 72 hours. At mass concentration of 10μg/L and 72 hours of culture, alkaline phosphatase secretion could be promoted in the T>C group. At mass concentration of 20μg/L and 24 hours of culture, the promoting effect on alkaline phosphatase secretion was most significant in the TC group (P<0.05). Results confirm that active ingredients of Kidney Recipe compatibility proportion can promote osteoblasts proliferation and differentiation most strongly in the T>C group in the time-effect and the dose-effect relationship.
