ABSTRACT
Objective:To explore the clinical significance of serum nuclear factor κ B, interleukin(IL)-4, IL-10, IL-12, interferon(IFN)- γ expression in subclinical hypothyroidism with gestational diabetes mellitus.Methods:Thirty pregnant women with subclinical hypothyroidism combined with gestational diabetes mellitus in Tangshan Maternal and Child Health Hospital from January 2017 to October 2018 were retrospectively analyzed as group A. Thirty three pregnant women with subclinical hypothyroidism were selected as group B, 35 pregnant women with gestational diabetes mellitus as group C and 40 healthy pregnant women as control group.ELISA was used to detect NF-κB, IL-4, IL-10, IL-12 and IFN-γ, and the results were analyzed and compared.Results:The serum levels of NF-κB were (15.91±5.68), (13.22±5.23), (12.97±5.11), (9.74±3.85) μg/L, IL-12 were (28.91±6.84), (21.64±5.72), (22.23±5.91), (13.68±3.76) ng/L, and serum IFN-γ levels were (23.74±5.55), (18.26±4.63), (17.85±4.31), (12.69±3.85) ng/L in A, B, C and the control group respectively.There were statistically significant differences in the three indicators between groups ( F=5.118, 6.821, 7.133, all P<0.05), and group A was higher than group B, C and control, the differences were statistically significant (all P<0.05); the levels of serum IL-4 in group A, B, C and control group were (8.91±3.99), (10.84±4.47), (11.27±4.62), (13.68±5.46) ng/L, respectively.The levels of serum IL-10 were (10.91±3.86), (13.05±4.58), (12.83±4.69), (15.82±5.33) ng/L, respectively.The differences of serum IL-4 and IL-10 between groups were statistically significant ( F=5.075, 5.616, all P<0.05), and serum IL-4 and IL-10 in group A were lower than those in group B, group C and control group.The levels of serum IL-4 and IL-10 in group B and C were lower than those in control group (all P<0.05). Conclusion:The activation of NF-kB signaling pathway and its related cytokines may be the influencing factors for the development of subclinical hypothyroidism with gestational diabetes mellitus.

ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the operation time and clinical effect of three types of materials (i.e., total-etching adhesive, self-etching adhesive, resin-modified glass ionomer cement) that are used to bond removable thermoplastic appliances.</p><p><b>METHODS</b>Thirty malocclusion patients (156 attachments) with removable thermoplastic appliances were randomly divided into three groups, with 10 individuals each. Attachments of groups A and B were bonded using 3M Adper Single Bond 2 and 3M Adper Easy One, respectively; both adhesives utilized 3M Z350 nano composite resin. Attachments of group C was directly bonded using GC Fuji Ortho LC. The operation time of each attachment was recorded. Failure rates of adhesion were evaluated during adhesion, 1 month after treatment, and 6 months after treatment.</p><p><b>RESULTS</b>The operation time of group C was shorter than those of groups A and B (P<0.01). Significant difference of adhesion failure rates was not found among the three groups (P>0.05). No significant difference of adhesion failure rates was also observed in different times of the same group (P>0.05).</p><p><b>CONCLUSION</b>The attachment stability of the three types of materials achieved satisfactory effects. However, the operation method of resin-modified glass ionomer cement is more concise and suitable for clinical promotion.</p>

Objective To investigate the effects of different durations of methamphetamine abuse on spatial cognitive processing.Methods The mental rotation task was used to evaluate the spatial processing function of 35 methamphetamine abusers and 30 healthy subjects.The methamphetamine abusers are divided into 2 groups according to their abuse durations,group 1 contains 16 abusers with an average duration of 1 year and group 2 contains 19 abusers with an average duration of 3 years.Participants were asked to judge the right hand/food or the left hand/food of the experimental stimuli at difference angles.The reaction time (RT) and the accurate rate (AR) of the mental rotation task were recorded.Results Compared with the control group,RT of group 1 methamphetamine abusers was longer at the angle of 0°((1469±318)ms) and 180°((1718±412)ms) (P＜0.05),RT of group 2 was longer at the angle of 0°((1466±243) ms),60°((1497±294) ms) and 180°((1708±288) ms) (P ＜0.05).And the AR of methamphetamine abusers was higher at every angle (P＜0.05).Conclusion Long-term dependence on methamphetmine can damage the abuser's spatial processing function.
ABSTRACT
Objective To investigate the association between global registry of acute coronary events (GRACE) score,N-terminal pro brain natriuretic peptide (NT-proBNP) and heart function in patients with acute coronary syndromes(ACS).Methods One hundred and seventy-four ACS patients and 60 healthy persons were enrolled our study.Of ACS patients,96 cases were with unstable angina pectoris(UP) and 78 cases with acute myocardial infarction (AMI).The level of NT-proBNP,left ventricular ejection fraction (LVEF) and GRACE score were measured.Results The NT-pro BPN of patients with UP or AMI were 87.00(38.25,245.75) ng/L and 686.00 (169.00,1 852.75) ng/L,and GRACE score were (87.51 ± 17.69) and (134.74 ± 23.56),which were higher than that in the control group (31.50 (13.00,54.75) ng/L,(81.10 ± 15.75)).LVEF in patients with AMI (57.72 ± 9.04) ％,lower than that of the control group ((64.45 ± 6.31) ％),and there were statistically significant difference among the three groups (Z =44.111,P ＜ 0.001 ; F =172.366,18.176,P ＜0.01).There was positive correlation between serum NT-pro BNP levels and GRACE score(r =0.451,P ＜ 0.001),and negative correlation was seen between serum NT-pro BNP and LVEF (r =-0.294,P ＜ 0.001)Conclusion NT-pro BNP level increases and LVEP decreases in patients with ACS and they are related to GRACE score as well as associated with the degree of risk in patients with ACS.
