Objective To observe the changes of macular choroidal thickness before and after laser treatment for diabetic retinopathy patients.Methods For patients with diabetes by fundus fluorescein angiography (FFA) examination,diagnosed as severe non-proliferative and proliferative diabetic retinopathy and in accordance with the laser photocoagulation treatment indications of 23 patients (45 eyes) included in the study.There were 10 cases of male,13 cases of female; the average age was (55.48±5.43) years old.All patients underwent macular grid laser photocoagulation and pan-retinal photocoagulation.The macular choroidal thickness before and after laser treatment was measured by enhanced depth imaging technique of optical coherence tomography during follow-up at 1,2,3 weeks and one month at specific sites of choroidal.The specific sites included subfoveal choroidal thickness (SFCT),from the foveal 1mm,3mm,6mm distance of nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT).Results One week after the treatment,SFCT,NCT1 mm,NCT3 mm,TCT1 mm,TCT3 mm,TCT6 mm were obviously thickening (t=4.728,4.422,3.759,3.743,5.713,2.502; P＜0.05).Two weeks after the treatment the SFCT,NCT1 mm,NCT3 mm,TCT1 mm,TCT3 mm were decreased gradually (t =3.189,2.122,2.742,2.196,2.076 ; P＜0.05).The choroidal thickness returned to pretreatment level from 2 weeks to 4 weeks after treatment,the NCT6mm had no obvious change in the whole treatment period(P＞0.05).Conclusion The choroidal thickness was significantly thicker after laser photocoagulation treatment within 1 week,with the time prolonging the choroidal thickness gradually decreases.

AIM: To study the effects of aspirin-niacinamide-zinc complex (WUY) on platelet aggregation and experimental thrombosis. METHODS: With adenosine diphosphatethe (ADP), arachidonic acid (AA) and collagen, the effects of aspirin-niacinamide-zinc complex (WUY) on platelet aggregation in vitro or in vivo were investigated by Born's method. The mouse mortality caused by intravenous injection of AA and experimental thrombus formation in rats were observed. Radioimmunoassay was used for measuring thromboxane B_2 (TXB_2) and 6-keto-PGF_(1?) in plasma of rabbits. RESULTS: In high, middle and low dose groups, drugs, in vitro, inhibited ADP-, AA-and collagen-induced platelet aggregation and the effect of WUY was stronger than that of ASP in high dose groups. In vivo, WUY showed more potent inhibitory effects on AA-induced aggregation in 1 h and 3 h. WUY had a powerful inhibitory effect on mouse death as a result of pulmonary thrombi induced by AA injection into the tail vein and ED_(50) was lower than that of ASP. In addition, WUY exhibited strong inhibitory effect on thrombus formation in rat arteri-venous shunt and significantly reduced plasma level of TXB_2 while it markedly increasing 6-keto-PGF_(1?) in high dose groups and ASP significantly reduced plasma level of both TXB_2 and 6-keto-PGF_(1?). CONCLUSION: The effect of WUY on platelet aggregation and experimental thrombosis is stronger than that of ASP and can increase plasma level of 6-keto-PGF_(1?).

BACKGROUND: In recent years, epidemiological studies have found that the saturation of transferring or the increased level of serum ferritin are associated with the attacks of cancer, coronary heart disease, diabetes mellitus, Parkinson disease, liver disease and the diseases of immune system. Therefore, it is suggested that the intake of excessive iron may cause adverse influence on the healthy of human body.OBJECTIVE: To establish high-iron model in mice by using full-rate diet pellets by adding regular quantitative intraperitoneal injection of iron dextran, and observe the iron levels in vivo and the changes of organ coefficients.DESIGN: A comparative observation.SETTING: Department of Nutrition and Food Hygiene, School of Public Health and Tropic Medicine, Southern Medical University.MATERIALS: The experiment was carried out in the laboratory of the Department of Nutrition and Food Hygiene, School of Public Health and Tropic Medicine, Southern Medical University in May 2006. Forty Kunming mice of SPF grade, 20 males and 20 females, weighing 18-22 g, were provided by the Animal Experimental Center of Southern Medical University. The mice were randomly divided into control group (n =10) and high-iron model group (n =30) by introperitoneal injection of saline and iron dextran respectively, and the latter group was subdivided into low, middle and high-dosage groups (6.25, 12.5 and 25 g/L) respectively, 10 mice in each group. Full-rate diet pellets (iron content was 370 mg/kg)were purchased from the Animal Experimental Center of Southern Medical University. Iron dextran reagent (norm: 2 mL containing 50 mg iron) was the product of Zhejiang Ruian Pharmaceutical Factory (certification number: H33021758).The kits of superoxide dismutase (SOD) and maldondialdehyde (MDA) were provided by the Nanjing Jiancheng Bioengineering Institute.METHODS: Mice in each group were raised in plastic stainless steel cages respectively at (23±3) ℃, and they were free to the access of food and deionized water. Mice in the low, middle and high-dosage group were treated with intraperitoneal injection of iron dextran once every other day, 0.8 mL for each time, whereas iron dextran was replaced by saline in the control group, all the mice were treated for 6 weeks, and their nutritionol conditions were observed. All the mice were killed at the end of the 6th week. The iron contents in organs of heart, liver, spleen, lung and kidney, and serum were determined with atomic absorption spectrophotometer and automatic biochemical analyzer respectively; Pathohistological examination of organs were performed; The organ coefficients of liver and spleen were calculated; MDA content and SOD activity in serum were determined.MAIN OUTCOME MEASURES: General conditions of mice in each group; Iron contents in organs and iron concentration in serum; Organ coefficients of liver and spleen; MDA content and SOD activity in serum; Pathological changes.RESULTS: In the high-iron model group, the body figures of the mice were changed, body masses were obviously decreased. The iron contents in organs and serum of mice in the high-iron model group were all obviously increased as compared with those in the control group (t =5.841, P ＜ 0.01), the organ coefficients of liver and spleen were also markedly increased (t =5.841, P ＜ 0.01), which were all in a dosage-dependent manner. The MDA content in serum was obviously increased (t =5.841, P ＜ 0.01) whereas the SOD activity was obviously decreased (t =12.924, P ＜ 0.01) as compared with those in the control group. The pathohistological examination under light microscope showed that there were pathological damages of different degree occurred in the tissue and cells and cell degeneration was observed,which affected the normal physiological function of cells.CONCLUSION: High-iron mice models can be successfully established by the intraperitoneal injection of iron dextran.The storage of excessive iron in vivo will result in the organic damages.

BACKGROUND: Iron deficiency anemia (IDA) is one of the highest incidence nutritional-deficiency diseases all over the world; especially infants and children are the main group. IDA presently becomes one of the most important nutritional problems to be solved.OBJECTIVE: To observe the effect of chocolate carrier and orange juice on recovery of IDA model rats.DESIGN: Randomized controlled animal study.SETTING: Laboratory of Nutrient and Food Hygiene, School of Public Health and Tropical Medicine, Southern Medical University.MATERIALS: The experiment was carried out in the Laboratory of Nutri ent and Food Hygiene, School of Public Health And Tropiacal Medicine, Southern Medical University from March to June 2006. A total of 60 healthy SD rats of clean grade were provided by Animal Center of Southern Medical University (certification: 2002-009 2005A047). METHODS: ① Establishment of IDA models: Among them, 20 rats of half genders were randomly selected toregard as control group, and other 40 were regarded as model group. Rats in control group were fed with rou tinefeed and drank freely. Rats in model group were fed with AOAC-modi fied low-dosage iron feeds to establish IDA models by blooding at caudal vein. Three weeks later, average concentration of ferrohemoglobin in model group was decreased to about 90 g/L, and this suggested that model estab lishment was successful. Ten rats of half genders in each group were ran domly sacrificed. Pre-experiment and 3 weeks of post-experiment, rats were weighed to measure concentration of ferrohemoglobin with hemoglobin cyanide (HiCN) technique, red blood cell count (RBC, direct method), serum iron (microparticle chemiluminescent immunoassa y and related kit) and concentration of serum transferrin receptor (STFR, ELISA method and related kit). ② Recovery test: Other 10 rats in control group were regarded as normal control group, and they were fed with routine feed and drank freely. The rest 30 rats of half genders in model group were randomly di vided into 3 subgroups: model control group, FeSO4 group and chocolate & orange juice group with 10 in each group. Rats in model control group were perfused with distilled water everyday; rats in FeSO4 group were per fused with FeSO4, and rats in chocolate & orange juice group were per fused with chocolate carrier and orange juice. The iron volume in the last two groups was 6 mg/(kg·d). At 40 days after intervention, the experiment was stopped. Concentration of ferrohemoglobin, RBC, serum iron, concentration of STFR and activity of plasma-protein aconitase were measured with atom-trapping atomic-absorption spectrophotometry; meanwhile, biological utilization rate of chocolate carrier & orange juice was calculated.MAIN OUTCOME MEASURES: ① Contents of herrohemoglobin, RBC,serum iron and STFR before experiment and after modeling; ② contents of ferrohemoglobin, RBC, serum iron, STFR and activity of plasma-protein aconitase before recovery test and at 40 days after experiment; ③ Related biological utilization rate.RESULTS: All 60 rats were involved in the final analysis without any loss. ① Comparison of blood index after modelling: Content of ferrohemoglobin, RBC and content of serum iron were lower in model group than those in control group (P ＜ 0.01), but content of STFR was higher than that in control group (P ＜ 0.01). ② Comparison of blood index and activity of plasma-protein aconitase in liver before recovery test and at 40 days after experiment: At 40 days after intervention, concentration of ferrohemoglobin,RBC and content of serum iron were higher in FeSO4 group and chocolate & orange juice group than those in model control group (P＜ 0.01); however, content of STFR was lower than that in model control group (P ＜ 0.01).At 40 days after intervention, activity of plasma-protein aconitase in FeSO4 group and chocolate & orange juice group was higher than those before recovery test (P ＜ 0.01). ③ Related biological utilization rate of chocolate carrier plus orange juice: Biological utilization rate of FeSO4 was regarded as 100%, and biological utilization rate of chocolate carrier plus orange juice was increased remarkably (106.7%).CONCLUSION: Chocolate carrier plus orange juice can improve IDA function and wildly use on treating IDA because of its good absorption. It is characterized by well biological utilization rate and good taste; therefore,it is a hot topic for trophology and foods produce presently.

Objective To compare pharmacodynamics of vecuronium administered according to body surface area and body weight during general anesthesia.Methods Forty ASA Ⅰ or Ⅱ patients,aged 18-64 yr,weighing 40-85 kg,undergoing general anesthesia,were randomly divided into 2 group ( n =20 each ).The patients received vecuronium 2× ED95 based on body weight (group W) or based on body surface area (group S).Anesthesia was induced with propofol 2 mg/kg,fentanyl 3 μg/kg and vecuronium 0.1 mg/kg ( group W) or 2.824 mg/m2 (group S).The patients was tracheal intubated and mechanically ventilated when the maximal depression of T1 was achieved.PET CO2 was maintained at 35-45 mm Hg and BIS value was maintained at 40-50.The intubation condition was evaluated using Cooper's score.The onset time,maximal depression of T1,duration of clinical action,recovery index,duration of pharmacological action and amount of vecuronium consumed were recorded.The coefficient of variation for all the indexes mentioned above was calculated.Results There was no significant difference in the coefficient of variation for intubation condition,onset time,duration of clinical action,recovery index,and duration of pharmacological action between the two groups ( P ＞ 0.05).Compared with group W,the coefficient of variation for the maximal depression of T1 and amount of vecuronium consumed were significantly decreased in group S ( P ＜ 0.05).Conclusion Vecuronium 2 × ED95 administered according to body surface area can reduce the individual variation in pharmacodynamics during general anesthesia.
