Objective:To investigate the effect of fibrinogenase combined with aspirin on blood viscosity and clinical efficacy in patients with acute cerebral infarction.Methods:Senventy patients with mild to moderate acute cerebral infarction from October 2016 to June 2020 were collected from the Third People′s Hospital of Dalian. Patients were divided into control group and treatment group according to the random number table method, with 35 cases in each group. The control group was given oral aspirin plus an intravenous drip of normal saline equal to the treatment group, while the treatment group was given aspirin plus fibrinogenase by intravenous drip. Both groups were given symptomatic treatment such as management of blood glucose, blood pressure, arteriosclerosis plaque stabilization and improvement of circulation for 10 d. Blood viscosity and neurological deficit score were measured before and after treatment.Results:Compared with baseline values, WBV showed a slight decrease in all shear rates in the control group after treatment compared with that before treatment, but the difference was not statistically significant ( P>0.05). In the treatment group, all shear rates decreased compared with that before treatment ( P<0.05), and the effect of WBV was significant compared with that of the control group ( P<0.05). The improvement of neurological function in the treatment group was better than that in the control group. The significant efficiency and the total effective rate in the treatment group were significantly higher than those in the control group: 34.3% (12/35) vs. 25.7% (9/35), 88.6% (31/35) vs.71.4% (25/35). Conclusions:Fibrinogenase combined with aspirin in the treatment of acute cerebral infarction patients can safely and effectively reduce blood viscosity and improve clinical symptoms.

BACKGROUND:At present, there are stil differences in the studies of total-etch, self-etch and self-bonding resin cement effect on the coronal microleakage and bonding strength of fiber posts.
OBJECTIVE:To evaluate the coronal microleakage and the bonding strength of fiber posts treated with three kinds of resin cements.
METHODS:Total y 32 upper incisors were randomly divided into five groups, including three experimental groups and two control groups. After the root canal preparation, three kinds of resin cements (EMBRACE WetBond, LuxaCore, Medental Multi-cure) were used to fiber posts with the bond diameter of 1.4 mm. Stereomicroscope was used to observe the microleakage. Then, the specimens were cut into 2 mm wafer along the axis of tooth, and universal testing machine for push-out test was used to observe the failure mode. In the positive control group, no root canal preparation was done, the root was coated with nail polish, and the crown was directly exposed to the dye. In the negative control group, no root canal preparation was done, the root canal orifice was covered with the resin, the tooth was overal coated with nail polish and then embedded 1 mm below the section.
RESULTS AND CONCLUSION:The microleakage was observed in al the three resin cements, Medental Multi-cure showed the least microleakage and LuxaCore showed the largest microleakage, and there was significantly different among the three kinds of resin cements (P<0.05). The bonding strength of three cements had significant differences (P<0.05), and ranked from high to low:Mdental Multi-cure, LuxaCore, and EMBRACE WetBond. The main fracture modes were binder/fiber post fracture and mixed failure. The results suggest that the total-etch resin cement binds tightly with the dentin, and owns a superiority in the microleakage and bonding property as compared with the self-etch resin cements and self-bonding resin cements.

Objective To investigate the relationship between serum thyrotrophin(TSH)and dyslipidemia in subclinical hypothyroid and euthyroid subjects. Methods An epidemiological study on diabetes and thyroid diseases was performed in Dadong community, Shenyang city, in 2007. 110 subjects with subclinical hypothyroidism(SCH)and 1 240 euthyroid subjects were enrolled in the study. Neither history of thyroid diseases nor administration of thyroid-related and lipid-regulating medicines were reported in these subjects. The levels of serum thyroid hormones, lipids, fasting plasma glucose(FPG), and insulin were determined. Results (1)Patients with SCH had significantly lower HDL-C levels than those who were euthyroid.(2)According to the guideline of treatment of adult dyslipidemia in China, the lipid profiles were each categorized. Mean TSH levels were higher in subjects in the dyslipidemia subclass than subjects in the normal subclass. The differences were significant in high LDL-C subclass in overweight individuals. In euthyroid overweight women, mean TSH levels were significantly higher in high LDL-C subclass. In the euthyroid population, TSH was positively associated with total cholesterol in overweight population. The association was not modified by the homestasis model assessment for insulin resistance(HOMA-IR)values.(3)TSH was associated positively with serum triglycerides and negatively with serum HDL-C in women. TSH was positively associated with total cholesterol in overweight population and positively associated with total cholesterol and LDL-C in overweight women after adjustment for age, sex, and body mass index. Conclusion Raised serum TSH seems to be a risk factor of dyslipidemia in subclinical hypothyroid and euthyroid subjects, which is independent of insulin sensitivity.

Objective:To explore the mediating effects of disease perception on disease uncertainty and health behaviors among thrombolysis therapy in patients with acute ischemic stroke, to provide a theoretical basis for improving patient health behavior.Methods:By cross-sectional survey methods, from June 2021 to June 2022, a total of 123 thrombolysis therapy in patients with acute ischemic stroke were investigated by general information, Mishel Uncertainty in Illness Scale, Health Behavior Scale for Stroke Patients and Revised Illness Perception Questionnaire by convenience sampling method. The mediating effect of disease perception between disease uncertainty and health behavior was verified by structural equation model.Results:The scores of disease uncertainty, health behaviors and disease perception were (52.21 ± 7.67), (63.77 ± 9.40), (127.70 ± 26.19) points in patients with acute ischemic stroke. Health behaviors and each dimension including exercise, medication, instruction, nutrition, responsibility, tobacco and alcohol were negatively correlation between disease uncertainty ( r values were -0.762 to -0.411, all P<0.01), and positively correlation between disease perception ( r values were 0.689 to 0.912, all P<0.01). Disease uncertainty was a significantly negative predictor for health behaviors ( β= -0.71, P<0.01); disease perception was also a significantly negative predictor for disease perception ( β = -0.85, P<0.01). Disease uncertainty had a significantly indirect effect on the health behaviors for thrombolysis therapy in patients with acute ischemic stroke through disease perception, which showed the mediating effect of health behaviors accounts for 15.2% of total effect. Conclusions:Disease perception play a mediating role in the relationship between disease uncertainty and health behaviors among thrombolysis therapy in patients with acute ischemic stroke.

OBJECTIVETo investigate the effect of selenium supplementation on the selenium status and selenoenzyme, especially the activity and mRNA expression of type 1 deiodinase (D1) in mice with excessive iodine (EI) intake and to explore the mechanism of selenium intervention on iodine-induced abnormities.
METHODSWeanling female BALB/c mice were given tap water or 3 mg/L of iodine or supplemented with 0.5 mg/L or 1.0 mg/L of selenium in the presence of excessive iodine for 5 months. Selenium status, thyroid hormone level, hepatic and renal D1 activity and mRNA expression were examined.
RESULTSExcessive iodine intake significantly decreased the selenium concentration in urine and liver, and the activity of glutathione peroxidase (GSH-Px) in liver. Meanwhile, serum total T4 (TT4) increased while serum total T3 (TT3) decreased. Hepatic D1 enzyme activity and mRNA expression were reduced by 33% and 86%, respectively. Renal D1 enzyme activity and mRNA were reduced by 30% and 55%, respectively. Selenium supplementation obviously increased selenium concentration, activity of GSH-Px and Dl as well as mRNA expression of D1. However, increasing the supplementation of Se from 0.5 to 1.0 mg/L did not further increase selenoenzyme activity and expression.
CONCLUSIONRelative selenium deficiency caused by excessive iodine plays an essential role in the mechanism of iodine-induced abnormalities. An appropriate dose of selenium supplementation exercises a beneficial intervention.
