Objective To characterize pancreatic perfusion in swines with experimental chronic pancreatitis(CP)by dynamic contrast-enhanced MRI and to correlate it with the severity of CP.Methods Twenty-two swines were randomly selected and made CP by ligation of main pancreatic duct.Six healthy swines served as control.MR perfusion study with dynamic contrast-enhanced MRl was carried out on the swines under anesthesia.The animals were euthanized after MR perfusion exam.The swines were divided into 4 groups according to the histological results of pancreas:normal group,group of CP of grade 1,group of CP of grade 2,and group of CP of grade 3.The maximum perfusion slope rate,the time-to-peak value and the maximum enhancement rate was compared between the groups using variance analysis,and the relationship between each perfusion parameters and severity of CP was made by correlative analysis.Results Twenty-one swines underwent MR perfusion study,including 7 swines in normal group,7 in group of grade 1 CP,3 in group of grade 2 CP,and 4 in group of grade 3 CP.On signal intensity time curve(SI-T)derived from MR perfusion weighted imaging,the m~imum slope rate was(10.88±1.20)%,(10.59±1.02)%,(6.67±1.31)%,and(5.48±1.97)%for normal swines,swines with grade 1 CP,swines with grade 2 CP and swines with grade 3 CP,respectively(F=20.51,P<0.05).The time-to-peak value was(13.82±3.09)s,(12.31±5.52)s,(20.55±3.79)s and(37.26±14.56)s respectively(F=10.68,P<0.05).The maximal signal enhancement rate was(62.95±20.20)%,(60.44±20.00)%,(46.33±22.70)%,and(67.65±32.66)%,respectively(F=0.53,P>0.05).The highest slope value(r=-0.72,P<0.05)and the time-to-peak(r=0.54,P<0.05)of the SI-T curve were correlated to the severity of CP,respectively.However there was no linear correlation between the maximal signal enhancement rate and the severity of CP.Conclusion MR perfasion weighted imaging has a potential to diagnose and to grade experimental chronic pancreatitis.

Objective To observe the effects of comprehensive measures of changing grain,selenium supplementation,off-site education and resettlement on prevention of children's Kashin-Beck disease in Aba state.Methods Fifty eight villages in Aba Kashin-Beck disease areas were chosen as intervention points in Aba state Sichuan province from 2007 to 2011.Based on the implementation of prevention and control measures,the villages were divided into off-site education + changing grain + selenium supplementation group and resettlement + off-site education + changing grain + selenium supplementation group,Geletuo town of Seda county,Ganzi state was selected as a control point,and right-hand anteroposterior X-ray examination(including the wrist) was carried out on children aged 6-13 from 2007 to 2011 annually.Clinical and X-ray diagnosis of Kashin-Beck disease was made in accordance with the Diagnostic Criteria of Kaschin-Beck Disease(GB 16003-1995).The effects of prevention and control measures were evaluated by comparing the child X-ray detection rate before and after the implementation of the measures.Results The average X-ray positive detectable rate of children in the intervention points was 2.07%(66/3181),2.72% (69/2540),1.16% (35/3017),0.56% (19/3397) and 0.56% (24/4273),respectively from 2007 to 2011,with a downward trend (x2trend =66.74,P < 0.01).There was a downward trend in the average X-ray positive detectable rate of children in off-site education + changing grain + selenium supplementation group [1.60%(29/1809),2.63% (39/1484),1.29% (25/1941),0.64% (15/2332),0.42% (10/2379)] and resettlement + off-site education + changing grain + selenium supplementation group [2.70% (37/1372),2.84% (30/1056),0.93%(10/1076),0.38% (4/1065),0.74%(14/1894)] (x2trend=30.97,35.19,all P < 0.01).The average X-ray positive detectable rate of children in the intervention group was 0 from 2007 to 2010,and was 1.61% (1/62) in 2011.The difference of X-ray positive detectable rate was not statistically significant in the control group in the 5 years from 2007 to 2011.The difference of children's X-ray positive detectable rate was not statistically significant between control group and intervention group.Conclusions The effect of taking changing grain,selenium supplementation,off-site education and resettlement comprehensive measures to prevent children's Kashin-Beck disease is not significant in those places where the state of Kaschin-Beck disease is not active.

Objective To find out iodine nutritional status of pregnant women in the third trimester and the relationship between pregnant women and their neonates thyroid function in a high iodine area.Methods From April to June 2010,210 copies of fasting morning urine and venous blood,and their neonatal umbilical cord blood samples were collected in Haixing Hospital,Cangzhou city,Hebei province.Urinary iodine was determined by arsenic-cerium catalytic spectrophotometry.The levels of free triiodothyronine(FT3),free thyroxine (FT4) and sensitive thyroid-stimulating hormone (sTSH) in serum were measured by chemiluminescence.Results Median urinary iodine of 210 pregnant women(average age 27.69 ± 4.73 years) in the third trimester was 1240.70 μg/L,84.3%(177/210) of them was in excessive iodine nutrition,and only 0.5%(1/210) of them was in adequate iodine nutrition.The prevalence rate of thyroid diseases was 19.5% (41/210),and the spectrum of diseases were subclinical hypothyroidism(16.2%,34/210),subclinical hyperthyroidism(0.9%,2/210),hypothyroidism(2.4%,5/210) and hyperthyroidism (0,0/210).The number of newborns with sTSH 5 - > 10 mU/L were 104 persons (49.5%); 10 - > 20 mU/L were 44 persons(21.0%),and ≥20 mU/L were 16 persons(7.6%).Of pregnant women suffer from thyroid disease,the ratio(50.0%,24/48 ) of sTSH equal to 10.18 mU/L and > 10 mU/L of their neonates was higher than that of their corresponding non-ill pregnant women(6.78 mU/L,Z =- 2.867,P < 0.05; 22.2%,36/162,x2 =14.000,P < 0.05).There was a positive correlation between neonates' and their mothers' sTSH levels (r =0.278,P < 0.05).There was also a positive correlation between neonates' (sTSH > 10 mU/L) and their mothers' abnormal sTSH levels (r =0.240,P < 0.05).Conclusions Most of the pregnant women in high iodine areas are iodine excess.The level of neonates' sTSH is higher,and it is due to their mothers' abnormal sTSH and suffering from thyroid diseases to some extent.As a result,the monitoring of pregnant women's iodine nutrition and thyroid function and sTSH level of their neonates should be strengthened.

Objective To study the role of TNFα in the plasm a and skin and IL-1 in the serum in the formation of secondary thrombosis after skin avulsion. Methods After avulsive flap at size of 12 cm×4 cm was inflicted on the hind legs of pigs, skin specimens and venous blood sam ples were taken at various time points. The contents of TNFα in plasma and skin were determined with radio-immunoassay, and the activity of serum IL-1 wi th 3[H]-TdR. Results The TNFα contents in the plasma and skin were increased significantly after avulsion(P<0.01),which were (41 5±24) ng/L and (298±18.5) ng/L respectively on the 3rd day after the injury. T he activity of IL-1 in the serum was increased (P<0.05) and was (2.59± 0.85 ) ng/L on day 3. Conclusion The changes of TNFα contents and I L-1 activity in blood and skin play important roles in the inducetion and aggra vation of secondary tissue necrosis and early thrombosis after skin avulsion.

OBJECTIVETo investigate the systemic influence after an island flap with venous congestion-reperfusion.
METHODSAn island flap was formed in a Rat model. The vein in the pedicle was clamped for 2 hours, 6 hours and 10 hours and released. The ear microcirculation, levels of TNF alpha and IL-10 were measured, and the neutrophils sequestration in tissues were counted. The vascular structure of the lung and intestine were evaluated.
RESULTSThere were significant changes in the ear microcirculation, neutrophils sequestration of the lung and the intestine in the 2 hours, 6 hours and 10 hours groups, and became more serious by the time increasing. The TNF alpha level reached in maximum at 1 hour after the reperfusion, while the IL-10 became to the lowest level at 3 hours after the reperfusion. However, the TNF alpha and IL-10 levels were significant high in the 6 hour and 10 hours groups, compared with the 2 hours group and the control, but there was no differences between the2 hours group and the control.
CONCLUSIONSVenous congestion-reperfusion of flap could injury the remote organs such as lung, intestinal etc. The injury could be more serious with the time increasing.
