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 explore the combination of lamivudine and adefovir dipivoxiltreatment in HBeAg positive patients with inappropriate timing of decompensated hepatitis B cirrhosis.Methods Make a retrospective analysis of HBeAg positive patients with decompensated hepatitis B cirrhosis of the liver our hospital in 2014 January ~2015 January were,100 cases of initial treatment, 50 patients given lamivudine plus adefovir dipivoxil resistance as control group,50 cases patients given lamivudine plus adefovir dipivoxil combined as the observation group, compared two groups of clinical curative effect of treatment.Results Observation group after treatment in patients with HBeAgseroconversion rate of 26.00% was significantly higher than that in control group 4.00% (P<0.05);after 12 weeks of treatment in the observation group (9.63 ±1.42), 24 weeks(8.57 ±1.45), 48 weeks(7.43 ±1.57) Child-Pugh grading score was significantly lower than the control group(9.74 ±1.21),(9.45 ±1.33)(8.57 ±1.04)(P <0.05); level of HBV-DNA after treatment in the observation group (2.23 ±1.25) was significantly lower than that of the control group(5.18 ± 1.63), and the Patients in the observation group (2.23 ±1.25)HBV-DNA load in serum was significantly lower than that before treatment(6.47 ± 1.55)(P<0.05).Conclusion patients with decompensated hepatitis B cirrhosis with combination of lamivudine and adefovir dipivoxil treatment, the clinical efficacy is more significant, HBeAg seroconversion rate is increased , the score of Child-Pugh become low and improve liver reserve function, reduce HBV-DNA load in serum.

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.

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.

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 .

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.

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.

OBJECTIVETo determine whether oral statins can delay the progression of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS).

METHODSWe conducted a retrospective cohort study of 50-69-year-old males who came for physical examination in our hospital between January 2003 and December 2008. We designed the inclusion criteria, followed them up for 5 years, and investigated the relationship of oral statins with the clinical progression of BPH and LUTS.

RESULTSTotally, 653 men met the inclusion criteria and were included in this study, of whom 283 were treated with oral statins (group 1) while the other 370 with none (group 2). There were no statistically significant differences between the two groups in age and baseline IPSS, Qmax, and prostate volume (PV) (P > 0.05). During the follow-up, 24 cases in group 1 and 35 cases in group 2 were excluded for obvious dys-uria. A gradual increase was observed in IPSS in both groups 1 and 2 year by year from the baseline to the 5th year of follow-up, but significantly lower in the former group (4.27 +/- 1.16, 4.63 +/- 1.05, 5.27 +/- 0.96, 6.41 +/- 1.04, 7.21 +/- 1.21, and 7.93 +/-1.50) than in the latter (4.24 +/- 1.35, 5.26 +/- 1.23, 6.84 +/- 1.20, 8.75 +/- 1.84, 10.82 +/- 3.01, and 12.98 +/- 4.21) (P < 0.01); a gradual decrease was seen in Qmax, though markedly higher in group 1 ([26.56 +/- 2.09], [24.06 +/- 1.94], [21.33 +/- 1.66], [19.24 +/- 1.54], [17.44 +/- 1.53], and [16.27 +/- 1.37] ml/s) than in group 2 ([26.74 +/- 2.40], [23.62 +/- 2.01], [20.63 +/- 1.69], [17.72 +/- 1.48], [14.82 +/- 1.11], and [11.86 +/- 1.24] ml/s) (P < 0.01); and a gradual increase was found in PV, but remarkably smaller in the former group ([19.82 +/- 4.94], [22.60 +/- 4.99], [25.80 +/- 5.20], [27.92 +/- 5.05], [29.11 +/- 5.24], and [29.97 +/- 5.26] ml) than in the latter ([20.21 +/- 4.78], [24.30 +/- 4.98], [28.50 +/- 5.14], [32.84 +/- 4.77], [36.99 +/- 4.78], and [40.90 +/- 4.78] ml) (P < 0.01). Longer medication of statins was associated with better efficacy.

CONCLUSIONOral statins can significantly delay the clinical progression of BPH and LUTS.
