Objective To investigate the children's body environmental Se and T-2 toxin level in their staple food in Kaschin-Beck disease(KBD)relative active regions in Aba state of Sichuan province in 2008.Methods We took X-ray photograph of the right hand on children aged 7-13 years in 48 villages from 11 counties in Aba state.The relative active regions of KBD were chosen according to the X-ray result and historical status of KBD.The children's urine and hair,drinking water and their staple food werr sampled.Selenium contents in urine,hair,water and food samples were determined by naphthalene fluorescence,and T-2 toxin in staple food samples were detected by ELISA kits.Results In 2145 X-ray films,66 films were positive,and the children's KBD positive rate was 3.08%(66/2145).The KBD positive rate was respectively 10.98%(29/264)and 8.52%(19/223)in Maerkang county,Jinchuan county and it was 0.75%(3/400)in Rangtang county,historically serious endemic area.The selenium content in urine of children aged 7-13 years in Maerkang county,Jinchuan county and Rangtang county was (10.41±4.67), (10.11±3.65), (8.42±2.68)μg/g Cr, respectively, there was no statistical difference among three counties(F=0.901, P>0.05). The selenium content in hair of children aged 7-13 years in Maerkang county[(0.18±0.04)mg/kg] was lower than that in Jinchuan county[(0.21±0.04)mg/kg, P<0.05].The selenium content in water in Jinchuan county [(0.225±0.124 )μg/L ] was lower than that in Maerkang county and Rangtang county[(0.320±0.092), (0.339±0.105)μg/L, all P<0.05]. The selenium content in staple food in Jinchuan county(0.0033 mg/kg) was lower than that in Maerkang county and Rangtang county(0.0258,0.0137mg/kg, Z=-6.146,-3.042, all P<0.017). The T-2 toxin level in flour in three counties was 19.60,17.95,26.25 ng/g,respectively,there was no statistical difference among three counties(X2=5.623, P>0.05).The T-2 toxin level in grain Maerkang county (10.72 ng/g) was higher than that in Jinchuan county and Rangtang county (3.74,3.30 ng/g, Z=-6.315,-4.407,all P<0.017). T-2 toxin contamination in flour was more severe than that in grain (Z=-6.690,-5.493,-3.676, all P<0.05). Conclusions In 3 relative active KBD regions of Aba state,the children's selenium nutritional status and the T-2 toxin contamination level in their staple food is consistent with the distribution of KBD.

Objective To investigate the proliferation rule after autografl vein in autografl of vein and repairing arterial defect,discuss the minuteness structure changes related to time,and provide morphological date for the prevention and treatment of restenosis in clinic application.Methods Sixty canine femoral veins (3.5 cm and 5.5 cm) were excised,reversed and grafted to repairing femoral arterial defect using end- to-end anastomosis.During the period of 30-180 days excised the grafted veins,observed ultrastrural changes of endothelium,microstructural components relative content and patency in grafted veins through angiography, lipht microscope.Results Angiography show that the grafted vein wall get gradually thicker,vascular cavity get slender,and vessel elasticity shrinkage.Light microscope chalrify the ultrastructural changes of endotheh- um,the three lamine structure of grafted vascular wall could not be identified.Conclusion Grafted femoral veins had obviously arteriosclerosis trend after it was transplanted to the arterial system.Two months after the transplantation is the crisis time of the proliferation of the vascular wall.The effect of the proliferation of the grafted veins vascular wall and the impact of the hi-pressure of blood can lead some canine ruptured to die from pseudoaneurysms.

BACKGROUNDNon-valvular atrial fibrillation is associated with an increased risk of ischemic stroke; however, the appropriate intensity of anticoagulation therapy for Chinese patients has not been determined. The purpose of this study was to compare the safety and the efficacy of standard-intensity warfarin therapy, low-intensity warfarin therapy, and aspirin therapy for the prevention of ischemic events in Chinese patients with non-valvular atrial fibrillation (NVAF).

METHODSA total of 786 patients from 75 Chinese hospitals were enrolled in this study and randomized into three therapy groups: standard-intensity warfarin (international normalized ratio (INR) 2.1 to 2.5) group, low-intensity warfarin (INR 1.6 to 2.0) group and aspirin (200 mg per day) group. All patients were evaluated by physicians at 1, 3, 6, 9, 12, 15, 18, 21 and 24 months after randomization to obtain a patient questionnaire, physical examination and related laboratory tests.

RESULTSThe annual event rates of ischemic stroke, transient ischemic attack (TIA) or systemic thromboembolism were 2.6%, 3.1% and 6.9% in the standard-intensity warfarin, low-intensity warfarin and aspirin groups, respectively (P = 0.027). Thromboembolic event rates in both warfarin groups were significantly lower than that in the aspirin group (P = 0.018, P = 0.044), and there was no significant difference between the two warfarin groups. Severe hemorrhagic events occurred in 15 patients, 7 (2.6%) in the standard-intensity warfarin group, 7 (2.4%) in the low-intensity warfarin group and 1 (0.4%) in the aspirin group. The severe hemorrhagic event rates in the warfarin groups were higher than that in the aspirin group, but the difference did not reach statistical significance (P = 0.101). The mild hemorrhagic and total hemorrhagic event rates in the warfarin groups (whether in the standard-intensity warfarin group or low-intensity warfarin group) were much higher than that in the aspirin group with the annual event rates of total hemorrhages of 10.2%, 7.6% and 2.2%, respectively, in the 3 groups (P = 0.001). Furthermore, there was no significant difference in all cause mortality among the three study groups.

CONCLUSIONIn Chinese patients with NVAF, the warfarin therapy (INR 1.6 - 2.5) for the prevention of thromboembolic events was superior to aspirin.

OBJECTIVETo investigate the effect of Rongshi granule on osteopontin(OPN) expression.

METHODThe urlisthiasis rats were induced by ethylene glycol (EG) and ammonium chloride, the control group rats were non-treated, and the Rongshi granule groups (low-dose group, middle-dose group and high-dose group) were administered Rongshi granule in addition to EG and ammonium chloride in 21 days. Pooled 24 h urine samples from each group were collected weekly with the use of metabolic cages, the concentration of uric calcium and oxalic acid were respectively measured by EDTA and photoelectric colorimetric method. Eight animals from each group were killed at 0, 7, 14, and 21 days, kidneys were histologic examinaed and immunohistochemical staining.

RESULTThe expression of kidney osteopontin in model group was obviously higher than that of control group (P <0.01), and was up to the highest at 21 days with 1.4 times (0.281 3/0.201 8) of the control group. The expression of kidney osteopontin in all of the Rongshi granule groups were lower than those of model group (P < 0.05), with an obvious dose-dependent manner. The degree of the kidney calcium oxalate crystal of the rats in all the Rongshi granule groups was much lower than that of model group, and the uric calcium and oxalic acid were much lower than those of model group (P < 0.01).

CONCLUSIONThe Rongshi granule could inhibit the expression of osteopontin in rat urolithiasis model.

OBJECTIVE: To determine whether the introducer curving technique is useful in decreasing the degree of tilting of transfemoral Tulip filters. MATERIALS AND METHODS: The study sample group consisted of 108 patients with deep vein thrombosis who were enrolled and planned to undergo thrombolysis, and who accepted transfemoral Tulip filter insertion procedure. The patients were randomly divided into Group C and Group T. The introducer curving technique was Adopted in Group T. The post-implantation filter tilting angle (ACF) was measured in an anteroposterior projection. The retrieval hook adhering to the vascular wall was measured via tangential cavogram during retrieval. RESULTS: The overall average ACF was 5.8 +/- 4.14 degrees. In Group C, the average ACF was 7.1 +/- 4.52 degrees. In Group T, the average ACF was 4.4 +/- 3.20 degrees. The groups displayed a statistically significant difference (t = 3.573, p = 0.001) in ACF. Additionally, the difference of ACF between the left and right approaches turned out to be statistically significant (7.1 +/- 4.59 vs. 5.1 +/- 3.82, t = 2.301, p = 0.023). The proportion of severe tilt (ACF > or = 10degrees) in Group T was significantly lower than that in Group C (9.3% vs. 24.1%, chi2 = 4.267, p = 0.039). Between the groups, the difference in the rate of the retrieval hook adhering to the vascular wall was also statistically significant (2.9% vs. 24.2%, chi2 = 5.030, p = 0.025). CONCLUSION: The introducer curving technique appears to minimize the incidence and extent of transfemoral Tulip filter tilting.

The sequence variation of medicinal fish of Culter (Pisces: Cyprinidae) was analyzed by using cytochrome c oxidase subunit I (COI) sequencing collected from different regions of the Yangtze River basin, and we examine whether barcoding of COI can be used to discriminate medicinal fish of Culter. The AT content in the COI region of medicinal fish of Culter was higher than that of GC, which was similar with other species of Cypriniformes. Ninty-six percent of nucleotide changes were observed at the 3rd codon position of COI sequence, but the amino acid compositions translated by COI sequences of all Culter fish stayed the same. It is suggested that most synonymous mutations might occur at the 3rd position. The average Kimura-2-parameter (K2P) distance within-species was lower than 1%, and the K2P distance of pairwise-species was 10 times as much as that of within-species. The phylogenetic tree estimated by Neighbour-joining method indicated that species within genera invariably clustered, and generally so did individuals within species. Individuals from operational taxonomic units designated as different Culter species, supporting morphological evidence for each of these being separate species. It is suggested that the COI barcoding can be used to identify medicinal fish species of Culter.
