International Eye Science 2010;10(8):1459-1462
AIM:To investigate retinal vascular endothelial growth factor(VEGF)level and retinal cells apoptosis in the early stage of diabetic NOD mouse retina.METHODS:Animals were divided into the control group(non-diabetes mice)(2,4,6,8,12 weeks group,n=30)and diabetes group(2,4,6,8,12 weeks group,n=30).EUSA(Enzyme-Linked Immunosorbent Assay)was performed to detect VEGF level in both serum and retina.Transmission electron microscope method was used to examine retinal cell apoptosis.RESULTS:Compared with the control group,VEGF levels in serum and retina were increased significantly in the NOD group(12 weeks:4.9±0.4μg/g versus 0.19±0.1μg/g in serum sample,P < 0.01;165.0±9.0μg/g versus 18.0±4.0μg/g in retinal sample,P<0.01).There exists a positive correlation between serum VEGF and retinal VEGF levels in the early diabetic NOD mice(γ=0.9902,P=0.001).The number of the cells apoptosis in the ganglion significantly in the NOD group(P<0.01).CONCLUSION:The high VEGF expression may be contributed to increase retinal cells apoptosis.Many factors associated with retinal VEGF expression might involve in the early diabetes stage.
3.Spontaneous rodent models of diabetes and diabetic retinopathy
International Eye Science 2010;10(3):417-420
Diabetes is a complex and heterogeneous disorder presently affecting more than 100 million people worldwide and causing serious socio-economic problems. Spontaneous rodent models of diabetes mellitus have proved invaluable in understanding the pathogenesis, complications, and genetic or environmental influences that increase the risks of diabetes. We have reviewed here in the development and characterization of spontaneous rodent models that displayed most features commonly associated with diabetic retinopathy.

Objective To investigate the effects of deguelin on the proliferation inhibition and apoptosis induction in RPMI-8226 cells in vitro,as well as the regulation of steroid receptor coactivator-3(SRC-3)to explore the relationship between them.Methods The effect of deguelin on the growth of RPMI-8226 cells was studied by MTT assay.Apoptosis was detected through Hoechst 33258 staining and Annexin-V FITC/PI double-labeled cytometry.RT-PCR Technology was applied to assessment of the mRNA expression of SRC-3,whereas,SRC-3 protein expression and localization were determined by using immunohistochemistry method.Results Deguelin presented striking proliferation inhibition potency on RPMI-8226 cells in vitro and apoptosis induction activity in a time-and dose-dependent manner.The IC50 value for 24 h was(54.55?0.40)nmol/L,(17.04?0.73)% RPMI-8226 cells went apoptotic when treated with 25 nmol/L deguelin for 24 h,with the dose of deguelin increasing to 100 nmol/L,(63.57?1.36)% cells were apoptotic.Over-expression of SRC-3 was found in RPMI-8226 cells,whereas the mRNA and protein expression levels of SRC-3 were significantly downregulated in RPMI-8226 cells induced by deguelin in a dose-dependent manner.The disposition of SRC-3 was situated mainly at the nuclear,occasionally in the cytoplasm.Conclusion Deguelin exhibited potent proliferation inhibition to the human myeloma cell line RPMI-8226 cells,furthermore,deguelin might induce RPMI-8226 cells apoptosis in a dose-dependent manner,which might correspond to the regulation of the expression of SRC-3.

Aim To investigate the changes of heme oxygenase-1(HO-1) in cardiomyocytes after acute myocardial infarction and the impact of simvastatin on HO-1 expression in rats.Methods Myocardial infarction models were made by anterior descending coronary artery ligation on male SD rats whereas sham group by spurious ligation.Survivals were randomized into myocardial infarction(MI) group,simvastatin(Sim) group and sham group 24 hours after the operation.The Sim group was treated with simvastatin 40 mg?kg-1?d-1 via gavage till sacrifice.MI and sham groups were gavaged with equal volume of 0.9% NaCl at the same time.Rats were sacrificed at time points of 24 hours,7 days and 28 days after the operation,for the detection of HO-1 mRNA by RT-PCR,HO-1 protein level by Western bolt,activity of superoxide dismutase(SOD) and content of malondialdehyde(MDA) by spectrophotometric method in non-infarcted zone.Results Expression of HO-1 mRNA and protein level increased at 24 hours,peaked at 7 days and decreased to basal levels at 28 days.All the indexes at each time point mentioned above were significantly higher in MI group than those in sham group.At the 7th day and 28 th day after the operation,the indexes were higher in Sim group than those in MI group(P

Objective To investigate the reasonable proposal of prophylactic antibiotics use in plastic surgery with type Ⅰ incision.Methods The data of 748 patients with plastic surgery in our hospital were collected and the operation number was 770.Using a retrospective case-control study,we analysed the clinical effect of different administration methods.Results Clinical effects were compared among the multiple days medication group,normative administration group and no medication groups,and there was no significant difference in the prevention of postoperative infection results.Conclusions Plastic surgery with type Ⅰ incision does not need the prophylactic application of antibiotics.In special circumstances we should take medicine in strict accordance with the Guiding Principles for Clinical Application of Antibiotics.

OBJECTIVETo compare the difference in the clinical efficacy on perennial allergic rhinitis between three nasal points acupuncture therapy and the oral administration of loratadine so as to provide the better acupuncture program in clinical treatment.
METHODSSixty cases were randomized into an acupuncture group (30 cases) and a medication group (30 cases). In the acupuncture group, acupuncture was applied to three nasal points [Yingxiang (LI 20), Yintang (EX-HN 3), Bitong (Extra)] and acupoints selected by syndrome differentiation. Acupuncture was given once every two days, three times a week, for 4 weeks totally. In the medication group, loratadine was prescribed for oral administration, 10 mg every day, for 4 weeks. The symptom and physical sign scores before and after treatment, as well the short-term and long-term efficacy were compared between the two groups.
RESULTSThe total effective rate was 96.7% (29/30) in the acupuncture group and was 93.3% (28/30) in the medication group after treatment. The efficacy was similar between the two groups (P>0.05). In follow-up, the total effective rate was 86.7% (26/30) in the acupuncture group, which was better than 56.7% (17/30, P<0.05) in the medication group. The scores of symptoms and physical signs after treatment and in follow-up were all reduced apparently as compared with those before treatment in the patients of the two groups (all P<0.05). The scores of symptoms and physical signs were reduced more apparently in the acupuncture group as compared with those in the medication group in follow-up (all P<0.05).
CONCLUSIONThe acupuncture at three nasal points and the acupoints selected by syndrome differentiation achieves the similar short-term efficacy on perennial allergic rhinitis as compared with the oral administration of loratadine. The acupuncture therapy presents the obvious advantages on long-term efficacy.
