Chinese Journal of Tissue Engineering Research 2005;9(3):238-239
BACKGROUND:There are various reports on the effects of fish oil on lipid level at home and abroad.At present,the related researches domestically are carried on mostly taken rats as the animal model. OBJECTIVE:To study the influence of dietetic fish oil on lipid level of golden hamsters with hyperlipemia. DESIGN:A randomized controlled study. SETTING:The experimental animal center of a teaching hospital affiliated to a university. PARTICIPANTS:The experiment was performed in the Experimental Animal Center of Nanjing General Hospital from June to December 2001.Forty male golden hamsters weighing 70 to 90 g(bought from Shanghai Animal Experiment Center) were randomized into 4 groups with 10 in each, named as the control group,0.5 mL fish oil group,0.8 mL fish oil group and 1.2 mL fish oil group. INTERVENTIONS:The golden hamster models of hyperlipemia were established.Golden hamsters in the control group were treated with saline 1 mL per day,while in the 0.5, 0.8 and 1.2 mL fish oil groups, fish oil of various dosages was applied(0.5,0.8 and 1.2 mL per day) successively to observe the effects on lipid level. RESULTS:In the 0.8 and 1.2 mL fish oil groups, the levers of triglyceride(TG) were(3.91± 2.32) and(6.22± 3.81)mmol/L respectively,which were remarkably reduced as compared with that in the control group[(9.02± 3.90) mmol/L](t=3.46,P< 0.01;t=2.65,P< 0.05). The TG level in the 0.8 mL fish oil group was significantly different from that in the 0.5 mL fish oil group[(8.14± 3.84) mmol/L](t=2.92,P < 0.05).The level of cholesterol and high density lipoprotein(HDL) had insignificant differences(P >0.05). CONCLUSION:Dietetic fish oil acts on reducing blood TG,for which, the effect of the moderate dosage is the best. Its effects in reducing cholesterol and increasing HDL are not apparent.

Objective To acquire effective clues for identification of environmental risk factors to birth defects. Methods Spatial autocorrelation statistics Moran's I and spatial hotspots detect method Getis's G statistics was used to identify birth defect risk factor. Results The different kinds of birth defects have different spatial distribution. Neural tube birth defects have the properties of spatial autocorrelation and different clustering phenomena in different spatial scales. Two typical spatial patterns were discovered in spatial scales of about 6.84 kilometers and 22.8 kilometers. Conclusion Using spatial autocorrelation probing technique, we find that there may be some common environmental teratogenetic factors which affect birth defects occurring ratio in the study area. By hotspots analysis of the clustering phenomena, the risk factors leading to birth defect were further resolved.

Objective To explore the significance of mediastinum drainage tube in prevention and treatment of intrathoracic anastomotic leak after esophagectomy. Methods The morbidity and prognosis of intrathoracic anas-tomotic leak after esophagectomy in 180 patients with esophageal or cardia carcinoma (group A) who used mediasti-num drainage tube in operation from 2006 to 2008 was studied retrospectively,and were compare with 154 patients (group B) without mediastinum drainage tube from 2004 to 2006. Results The morbidity of intrathoracic anasto-motic leak after esophagectomy was 1.67% (3/180) in group A,and 4.55% (7/154) in group B,but no difference between them(χ2=1.4807, P>0.05) were found. Compared to group B, the final diagnosis of anastomotic leak in group A was early [(6.7±0.6) vs (10.0±2.1) days after operation (t=2.62, P<0.05)] and the duration of fe-ver was short [(5.3±1.5)vs (43.0±20.9) hours (t=4.39, P<0.01)]. The prognosis of 3 cases in group A was well, who all recovered without operation and had shorten hospital days than group B [(23.7±5.9)d vs (45.3± 5.0)d,t=4.86,P<0.01)]. In 7 cases of group B,there were 5 cases underwent second operation,but only 3 cases recovered, the case fatality rate was 2.60% (4/154), higher than in group A (0, Fisher, P<0.05). Conclusions Although the mediastinum drainage tube used or not used in esophagectomy is unrelated with the occurrence of anas-tomotic leak, and the significance to use it is that it can help to discover anastomotic leak early, and control mediasti-num infection effectively without reoperation,and improve patients' prognosis.
