Ophthalmology in China 2009;18(4):279-282
Objective To investigate the duration of the first-fundus-examination and the status of diabetic retinopathy in patients with type 2 diabetes mellitus. Design Questionnaire. Participants 956 patients (1905 eyes) with type 2 diabetes in Tongren Eye Center of Beijing Tongren Hospital. Method Self-designed questionnaire was carried out. Patients were divided into different groups by the du-ration of the first-fundus-examination, degree of diabetic retinopathy, duration of diabetes, education background and living area in the data analysis. Main Outcome Measurements Duration of the first- fundus-examination, degree of diabetic retinopathy. Results Dia-betes patients in shorter duration groups finished the first-fundus-examination earlier than in longer duration groups (all P <0.05). Dif-ferent education background didn't show significant influence on duration of the first fundus examination. Urban patients received earli-er first-fundus-examination than rural patients (all P <0.05). The incidences of vitreous hemorrhage, retinal detachment and retinal pho-tocoagulation were rising with the duration of diabetes. The proportions of vitreous hemorrhage and retinal photocoagulation were higher in primary-school education group than in middle-school and college education groups (all P<0.05). Difference of the incidences of vit-reous hemorrhage and retinal detachment weren't found between in Beijing and non-Beijing patients. The incidences of vitreous hemor-rhage and retinal detachment in urban patients were higher than in rural patients (all P<0.05). Conclusion The most diabetic patients finish the first-fundus-examination much later than requested. Diabetic patients in lower-education-level groups and in rural group are even later, and their conditions are more serious.(Ophthalmol CHN, 2009, 18: 279-282)

Objective To evaluate the multi-slice spiral CT scan of liver dynamic dual-phase three-dimensional vascular imaging portal phase clinical value. Methods 80 cases in clinic, who were patients with liver function and imaging diagno- sis of liver and portal hypertension in liver cirrhosis, and 20 cases of healthy persons were carried out multi-slice spiral CT dual-phase scanning. The workstation used volume rendering techniques (VR) and maximum density multi-planar recon- struction technique for reconstruction. Results The hepatic arterial phase VR image and MIP MPR images can clearly show the celiac trunk, splenic artery, hepatic artery or artery and its branches, including 2-3 grade tumor blood supply variation of blood vessels and blood vessels, the portal venous phase, VR images and MIP MPR images clearly show the 1-6 level structure and the portal vein and hepatic vein branches of 1-3, with strong three-dimensional sense of space. Conclusion The multi-slice spiral CT three-dimensional reconstruction of portal vein imaging is a fast and effective non-invasive an- giography techniques, contributing to the clinical choice of reasonable efficacy of treatment programs and follow-up.

AlM:To investigate the protective effect of astaxanthin (AST) on human retinal pigment epithelial (RPE) cells against oxidative damage induced by hydrogen peroxide (H2O2).METHODS:Human RPE cells were subcultured, cell activity was detected by MTT, rate of apoptosis was detected by flow cytometry and cell ultrastructure changes were observed under transmission electron microscope. RESULTS: MTT results showed that cell activity elevated to ( 53. 66%± 3. 25% and 70. 43%± 2. 38% after 10-8 mol/L and 10-4 mol/L AST treated. The difference had statistically significant (P<0. 05) compared with oxidative injury group (38. 76%± 3. 74%). Flow cytometry results showed that the apoptosis rate of RPE cells decreased to 30. 23%± 1. 91% and 12. 58%± 2. 12% in AST pretreated group, the difference was significant (P<0. 05) compared with oxidative injury group ( 42. 50%± 1. 94%); Electron microscopy showed that the morphology of cells gradually improved accompanied with the concentration of AST elevated.CONCLUSlON:AST may inhibit hydrogen peroxide-induced apoptosis of RPE cells, it can provide reliable evidence for pursue effective medicine to prevent and treat retina injury.

To evaluate the efficacy of Yupingfeng droppill and western medicine in treatment of allergic rhinitis, 76 patients from Beijing Shijitan hospital during April 2011 to May 2012 were selected and randomly divided into the treatment group (n = 44) and control group (n = 32). The treatment group was treated with Yupingfeng droppill and cetirizine tablets, the control group was treated with cetirizine tablets, the effect of the two groups was observed after 28 days, after treatment, the symptoms and inferior turbinate volume contrast of the two groups were better than before. The obvious effective rate and total effective rate were 84.09%, 95.45% and 46.87%, 56.25% in the treatment group and and control group. The differences in the obvious effective rate and total effective rate were statistically significant between two groups (P < 0.05), Yupingfeng droppill has the curative effect on allergic rhinitis, which is better than simple oral cetirizine tablets.

Succinic acid is widely used in the field of chemistry and food proces s. Compared to the traditional chemical synthesis, succinic acid production by fermentation has some benefits. The new process with competitive cost uses rene wable agricultural resources including green house gas CO 2 instead of fossil f uels and reduces pollution from chemical synthesis. In this article, research progr e ss in production of succinic acid by fermentation such as microorganisms, metabo lic pathways and its regulation, fermentation and isolation are briefly reviewed .

The research status is reviewed on taxonomic position, ecology, biological active matter and artificial cultivation of Shiraia bambusicola. Following problems are presented: whether there are new species and host specificity of Shiraia bambusicola. Since the artificial cultivation of stroma of Shiraia bambusicola has not been success, Shiraia bambusicola is in situation of emerge of itself and perish of itself so that it is not beneficial to resource protection and continual utilization of this medicinal fungus. It is pointed out that molecular biology of Shiraia bambusicola should be further researched and technology of artificial cultivation of Shiraia bambusicola should be explored in order to exploit and usage of Shiraia bambusicola.

The hexane extract from marine actinomycetes 124092 showed potent inhibition on B16 cell line by MTT assay. The hexane extract was fractionationed on silica gel column by vacuum liquid chromatography to afford 6 fractions(Fr1~Fr6), and Fr6 showed cytotoxic activity. To determine the bioacitve components of hexane extract, Fr6 was analyzed by GC/MS. The main components were identified as palmitic acid (11.76%), oleic acid (12.16%), linoleic acid (14.77%), and lactobacillic acid (61.31%). It have been reported that palmitic acid, oleic acid, and linoleic acid possess cytotoxic activity on rat ascites tumor cells and linoleic acid have suppressive effect on human lung adenocarcinoma cells.

OBJECTIVETo investigate the effects of simvastatin on the proliferation and apoptosis of prostatic epithelial RWPE-1 cells.
METHODSRWPE-1 cells cultured in vitro were treated with simvastatin at 0, 10, 20, and 40 μmol/L for 24, 48, and 72 hours followed by determination of their proliferation by MTT assay, and their apoptosis by flow cytometry. The mRNA and protein expressions of Bcl-2, Bax, and Cx43 were detected by fluorescence quantitative RT-PCR and Western blot, respectively.
RESULTSAfter 72 hours of treatment with simvastatin at 10, 20, and 40 μmol/L, the inhibition rates of the RWPE-1 cells were (21.07 ± 6.41)%, (34.87 ± 9.65)%, and (47.18 ± 10.88)%, respectively, significantly higher than (1.21 ± 0.54)% in the control group (P < 0.05) and in a dose-dependent manner (P < 0.05); the cell apoptosis rates were (0.066 ± 0.016)%, (0.126 ± 0.023)%, and (0.192 ± 0.025)%, respectively, remarkably higher than (0.015 ± 0.005)% in the control (P < 0.05) and also in a dose-dependent manner (P < 0.05); the mRNA and protein expressions of Bcl-2 were decreasing while those of Bax and Cx43 increasing with the increased concentration of simvastatin (P < 0.05). The expression of Cx43 was correlated negatively with that of Bcl-2 but positively with that of Bax.
CONCLUSIONSimvastatin inhibits the proliferation of prostate epithelial cells and induce their apoptosis by acting on the gap junctional intercellular communication.
