Background The neovascular form of the disease usually causes severe vision loss in a number of eye diseases.Special-domain optical coherence tomography (SD-OCT) provides high-quality in retinal imaging and the possibility of the measurement in vivo.Objective This study aimed to investigate the feasibility of SD-OCT dynamically measuring choroidal neovascularization (CNV).Methods CNV was induced in 30 left eyes of 30 clean Brown Norway(BN)rats by retinal photocoagulation with the laser parameter as follows: wavelength 532 nm,exciting power 200 mW,spot diameter 100 μm and irradiating time 50 ms.Bubble or less retinal bleeding was thought as Brunch membrane breakage and CNV model establishment.Fundus fluorescein angiography(FFA) was performed to determine the establishment of CNV model and scored based on the fluorescein leakage on 3,7,14,21 days after photocoagulation.Meanwhile,CNV memberane thickness (CMT) was dynamically measured in vivo as the maxiume value from retinal inner limiting membrane through choroidal vessel layer in various time points.Histopathologic examination was used in the 14th day to evaluate and verify the result of SD-OCT.The right eyes were as controls.Results FFA examination showed that disc-like leakage of fluorescein appeared in 7 days and extended in 14 days after photocoagulation with the scores of 1.6±0.4,2.5±0.6 and 2.4±0.5 in 7,14 and 21 days,showing a significant difference among them(F=13.11,P＜0.01).The fluorescein leakage score was significantly higher in 14 and 21 days than that of 7 days(both P＜0.05).CMT measured by SD-OCT was(76.33±10.09),(102.03±14.21)and(98.03±13.76) μm in 7,14 and 21 days after photocoagulation respectively,with a significant difference among 3 time points (F=23.25,P＜0.01),and that in 14 and 21 days was significantly declined in comparison with 7 days(both P＜0.05).The results of SD-OCT showed a consistent tendency with that of FFA.Histopathological examination showed CNV formation in 14 days after photocoagulation.Conclusions Experimental CNV model was successfully induced by laser photography.SD-OCT technology allows excellent visualization of CNV in vivo.

Background To study diabetic retinopathy (DR) related risk factors is very important in the prevention of DR.Platelet endothelial cell adhesion molecule-1 (PECAM-1) is an important mediator that mediates high blood glucose-induced vascular diseases in diabetic patients.However,its mechanism is still below understood.Objective This clinical study was to investigate the effect of serum level changes of PECAM-1 on DR in type 2 diabetic patients.Methods Fifty-four patients with type 2 diabetes were enrolled from the endocrinology department of the Third People' s Hospital of Nantong City.Fundus examination was performed using the ophthalmoscope and fundus fluorescence angiography (FFA) on all the patients,and these patients were grouped as the non-DR (NDR)group (18 cases),non-proliferative DR(NPDR) group (20 cases) and proliferative DR group (PDR) (16 cases) based on the DR staging criterion of the Chinese Medical Association (1987 version).Eighteen age-and gender-matched normal subjects served as the normal control group.Peripheral blood was collected,and serum PECAM-1 levels were assayed using ELISA.Serum HbA1c levels were detected using the high performance liquid colorimetric(HPLC) method.The correlation of serum PECAM-1 level with serum HbA1c level was analyzed.All results were compared among the groups.Results The serum PECAM-1 levels were (10.907 ± 2.792),(7.024 ±2.377),(5.231 ± 1.816) and (3.817 ± 1.045) μg/L,respectively,in the PDR group,NPDR group,NDR group and normal control group,showing a significant difference among the 4 groups (F =12.630,P =0.02).Serum PECAM-1 content was significantly higher in the PDR group when compared with the NPDR group,NDR group and normal control group (P＜0.05).The serum HbA1c levels were (12.596±3.148)％,(9.118±3.356)％,(5.491±1.017)％ and (4.992 ± 0.725)％ in the PDR group,NPDR group,NDR group and normal control group,respectively,with a significant difference among these 4 groups (F =7.130,P =0.015),and those in the PDR group and NPDR group were significantly elevated in comparison with the NDR group and normal control group (P＜0.05).Significantly positive correlations were seen between serum PECAM-1 level and HbA1 c level in the PDR group,NPDR group and NDR group (r=0.799,P＜0.01 ;r =0.647,P＜0.01 ;r =0.685,P＜0.01).Significantly more patients with a disease course of ≥ 10 years were in the NPDR group in comparison with the PDR group (P =0.023).Conclusions Increase of serum PECAM-1 level is closely associated with blood glucose level,and it is an important factor in the pathogenesis and development of DR.These results imply that control of blood glucose is crucial for the prevention of DR in patient with type 2 diabetes.

Objective To explore the causes of subclinical hypothyrodism in children and the effects of the interventional therapy with thyroixine on the course of it.Methods Two hundreds children with subclinical hypothyroidism were measured for thyroglobulin antibody(TGAb),thyroid microsomal antibody(TMAb) in the blood serum,examined by colord Dopplor ultrasonic,examined by fine needle aspiraton cytology of the throid and measured the rate of 131I absorbed by thyroid in order to find out the causes of the disease.Two hundreds cases were randomly divided into two groups on the base of the cause of diseases,treatment group 100 cases and control group 100 cases.The treatment group were treated by throxine 25-75 ?g/d and the therapeutic dosage were chosen with the normal value of free triiodothyronine(FT3),free thyroxine(FT4)and high sensitive thyrotropin(sTSH) in the blood serum .After one year thyroxine therapy were stopped.Thyroid function was examined 6 months later after stopping the thyroxine.Results Among all of the causes of subclinical hypothyroidism in children,Hasgumoto′s thyroiditis accounts for 56%,simple goiter accounts for 26%,antithyroid drug accounts for 6%,the lack of thyroxine substitution therapy on the hypothyroidism accounts for 5% and undefined causes accounts for 7% .The thyroid function could keep normal for 1 year with an alternative therapy with thyroxine on subclinical hypothyroidism in children.Half a year later after stopping thyroxine,the thyroid function turned normal in most of the children.There were obvious differences in the ratio of cure and the ratio of effectiveness between treatment group and control group (t=20.2,3.2 Pa

Objective To explore the dynamic changes of expressions of surfactant protein A,B(SP-A,B)and aquaporin5(AQP5)mRNA of specificity mark in alveolar epithelial cell(AEC)of premature rats with chronic lung disease(CLD)and those significances.Methods Eighty premature rats were randomly and equally divided into model group(hyperoxia group)and control group(room air group).CLD was induced by hyperoxia exposure.The gene expressions of SP-A,SP-B and AQP5 were assayed with reverse transcription polymerase chain reaction(RT-PCR)after 1,3,7,14 and 21 days.Results Compared with control group,in hyperoxia group,the levels of SP-A and SP-B mRNA increased from day 7(Pa

OBJECTIVETo investigate the effect of salidroside on hypoxia-induced apoptosis of corpus cavernosum smooth muscle cells (CCSMCs) in rats.

METHODSRat CCSMCs were cultured in vitro by the enzyme digestion method and identified by immunofluorescent staining of anti-alpha-SMA and anti-Desmin. The non-toxic dose of salidroside was determined by MTT assay. Low-oxygen mixed gas (1% O2, 5% CO2, and 94% N2) was piped into a modular incubator chamber to induce hypoxia. The CCSMCs were divided into a normal, a hypoxia, and a 32 microg/mL salidroside intervention group. The apoptosis of the CCSMCs was detected by flow cytometry and the expression of the caspase-3 protein determined by Western blot.

RESULTSThe majority of the CCSMCs were positive for alpha-SMA and Desmin at immunofluorescent staining. Salidroside at < 32 microg/ml produced no obvious toxicity to CCSMCs. Compared with the normal control group, the rates of early and late apoptosis of CCSMCs were both increased significantly in the hypoxia group ([12.77 +/-1.41]% vs [18.69 +/- 1.29]%, P < 0.01 and [14.63 +/- 2.00]% vs [21.03 +/- 1.530]% , P < 0.05). Western blot showed a markedly increased expression of cleaved caspase-3 (P < 0.01). Intervention with 32 microg/ml salidroside significantly reduced hypoxia-induced early apoptosis of CCSMCs ([13.46% +/- 1.87]%, P < 0.01) and decreased the expression of cleaved caspase-3 (P < 0.01).

CONCLUSIONSalidroside can reduce the expression of cleaved caspase-3 and inhibit hypoxia-induced apoptosis of CCSMCs in rats.
