Objective:
To analyze the relationship between thrombin activatable fibrinolysis inhibitor ( TAFI ) and coronary heart disease ( CHD ), and to provide evidence for the prevention of CHD.
Methods:
The patients with CHD in Fushun Central Hospital in Liaoning Province were selected as the case group, the patients without CHD in the same hospital and period were selected as the control group. The demographic information and clinical examination results ( serum TAFI, lipid, glucose, etc. ) were collected to analyze the association between TAFI and CHD by logistic regression models.The multivariate logistic regression analysis was used to explore the relationship between TAFI and CHD.
Results:
There were 222 cases, including 100 cases of stable angina, 44 cases of unstable angina and 78 cases of acute myocardial infarction, and 222 controls. The median ages of cases and controls were 62 and 57 years old. The results of multivariate logistic regression analysis showed that serum TAFI>22.88 μg/mL ( P75 of controls ) was associated with the risk of CHD ( OR=1.619, 95%CI: 1.011-2.593 ), unstable angina ( OR=2.917, 95%CI: 1.433-5.939 ) and acute myocardial infarction ( OR=2.626, 95%CI: 1.007-6.847 ).
Conclusion
The high level of TAFI is related to CHD, unstable angina and acute myocardial infarction.

This study is to evaluate the effects of Shenmai injection on the temporal alterations of action potential (AP), early afterdepolarization (EAD) and delayed afterdepolarization (DAD) in papillary muscles. The action potentials were recorded by a glass electrode. APD at 90% repolarization (APD9 ) was measured, and spontaneous EAD and DAD were observed. The results show APD90 was significantly prolonged in model group compared with sham-operated group, whereas it was remained unchanged in Shenmai injec- tion treatment group and amiodarone group. The spontaneous EADs and DADs were frequently visible in model group. In conclusion, EAD, DAD and trigger activities increase gradually during pathological progression of rat cardiac hypertrophy, and Shenmai injection could improve the action potential change in rat cardiac hypertrophy.

Objective To identify the outcome of pregnancy and the alteration of renal function in women with nephrotic syndrome. Methods From 2003 to 2007, 59 pregnant women with nephrotic syndrome in our hospital were enrolled in the study. Their clinical data were retrospectively analyzed, including the time of kidney disease onset, 24-hour proteinuria, serum albumin, serum creatinine, blood uric acid, blood pressure, fetal survival, fetal mortality, rate of premature delivery, birth weight of the newborn, and proteinuria, renal function, blood pressure of the patients during their postpartum follow-up. Logistic regression analysis was used to identify the risk factors influencing the outcome of the patients and the newborns. Results The average gestational week was (20.35±9.40) weeks when proteinuria was detected in these pregnant women. The 24-hour proteinuria ranged from 3.5 to 15 g/24 h (median 5.1 g/24 h). The serum albumin was between 10 and 28 g/L (median 22.5 g/L). The serum creatinine was between 32 and 825 μmol/L (median 84 μmol/L) and the serum uric acid ranged from 196 to 793 μmol/L (median 385.5 μmol/L). Pregnancy-induced hypertension syndrome occurred in 75% of the patients, among whom 55.5% suffered from preeclampsia. Forty-three (72.9%) newborns survived , among whom 76.7% (33/43) were premature births and 62.8% (27/43) were low birth weight infants. 50% of the pregnant women still had nephrotic syndrome after delivery. 75% of 24 patients with pre-existing chronic glomerulonephritis had increased proteinuria during pregnancy. Among the 38 patients with renal insufficiency, 36.8% had poorer renal function after delivery. 23.7% of the patients progressed into end stage renal failure after delivery, 80% of whom had serum creatinine ≥ 265 μmol/L. 89% of the patients had persistent hypertension after childbirth. The Logistic regression analysis indicated hyperuricemia during pregnancy (P=0.018, OR=1.012) and the increase of serum creatinine (P=0.039, OR=1.005) were risk factors of renal failure in pregnant women after delivery. Hyperuricemia (P=0.012, OR=1.006)was the risk factor of fetal death. Conclusions Pregnancy with nephrotic syndrome leads to a low fetal survival. Hyperuricemia is the most important risk factor of the poor outcome of pregnant women and newborn.

Objective To analyze monitoring results of iodized salt and distribution characteristics of problem areas with non-iodized salt in Gansu province during 2001 - 2009 and to provide a basis to develop countermeasures to iodine deficiency disorders. Methods According to the criterion of "The National Scheme of Iodized Salt Surveillance", two levels of monitoring were carried out on production and wholesale-level(during 2001 -2007) and household-level(during 2001 - 2009). Salt iodine was determined by direct titration method (GB/T13025.7-1999), and Sichuan salt or special salt was determined with an arbitration method. Criteria for qualified iodized salt was (35 ± 15)mg/kg(20 - 50 mg/kg), and for non-iodized salt was < 5 mg/kg. Results During 2001 - 2007, a total of 4900 salt samples at production and wholesale-levels were examined, with a qualification rate of 97.80% (4792/4900). Non-iodized salt rates were all below 5% in Gansu province, consumption rate of qualified iodized salt was higher than 90% after 2003. During 2001 - 2009, cities(states) with non-iodized salt problems appeared 23 times, with Linxia accounting for 39.1%(9/23), Wuwei accounting for 21.7%(5/23). During 2001 -2009, counties(districts) with non-iodized salt problem appeared 123 times, including 68 times of ethnic minorities and state poverty counties, accounting for 55.3%(68/123). During 2001 - 2005 and 2006 - 2009, ethnic minorities and state poverty counties were accounting for 49.4%(44/89) and 70.6%(24/34) in counties with non-iodized salt problem. Conclusions The quality of iodized-salt at production and wholesale level is satisfactory in Gansu province, household consumption rate of qualified iodized salt have reached national standard for eliminating iodine deficiency disorders. But ethnic minorities and state poverty counties are main regions with non-iodized salt problem,these areas will be the key areas of prevention of iodine deficiency disorders in Gansu province in the future.

Background Research demonstrated that alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid GluR2 (AMPA-GluR2) is associated with amblyopia.It has been shown that levodopa and cytidine diphosphate choline can improve visual function of amblyopic children,but the mechanism is unclear.Objective This study was to explore the possible effects of levodopa and cytidine diphosphate choline on amblyopia.Methods Monocular deprivation (MD) animal models were created in 60 2-week-old SD rats by monolateral eyelid suturing and observed for 31 days and reared in natural light together with 15 other matched normal healthy SD rats.The models were randomly divided into the MD group,levodopa group,cytidine diphosphate choline group and normal saline control group,with 15 rats for each group.40 mg/kg of levodopa,80 mg/kg of cytidine diphosphate choline,I ml normal saline were given to the rats,respectively,for 28 consecutive days.Expressions of the AMPA-CluR2 protein and AMPA-CluR2 mRNA in the rat visual cortex were detected by immunohistochemistry,Western blot and real-time fluorescence quantitative PCR.Use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The expression values of the AMPA-GluR2 protein (AMPA-GluR2/β-actin) and AMPA-GluR2 mRNA (2-△△Ct) were significantly lower in the MD group than those of the normal control group (protein:0.32 ± 0.02 vs.0.64 ± 0.05,t =13.287,P<0.05 ;mRNA:0.30±0.01 vs.0.84±0.03,t=38.184,P<0.05).Those in the levodopa group were significantly increased in comparison with the normal saline solution group (protein:0.59 ±0.04 vs.0.33 ±0.03,t =11.628,P<0.05 ; mRNA:0.71±0.06 vs.0.33 ±0.02,t =13.435,P<0.05).The expression values of the AMPA-GluR2 protein and AMPA-GluR2 mRNA were significantly increased in the cytidine diphosphate choline group compared with the normal saline solution group (protein:0.52 ± 0.04 vs.0.33 ± 0.03,t =8.497,P < 0.05 ; mRNA:0.48± 0.04 vs.0.33 ± 0.02,t =7.500,P<0.05).Conclusions AMPA-GluR2 is associated with the plasticity of visual development.Levodopa and cytidine diphosphate choline may improve visual function by down-regulating the expression of AMPA-GluR2 in the visual cortex.
