Objective To investigate the role of hippocampal mu-opioid receptors (MORs) in the formation of seizure susceptibility induced by kainic acid (KA). Methods The SD rats were injected subcutaneously with a convulsive dose of KA (10 mg/kg). Then mini-osmotic pumps were used for intrahippocampal injection with a selective MOR antagonist ?-FNA, and a selective MOR agonist PL017 in these rats. 7 days later, the seizure susceptibility was checked by a subthreshold dose of KA (5 mg/kg). Results All animals showed motor seizures over Stage 4 after a convulsive dose KA injection. 7 days later, 100% animals showed seizures over Stage 4 in KA, CSF + KA and PL017+KA groups after injection of subthreshold dose of KA, but only 28.5% in PL017+KA group. Mean latency of PL017+KA group was (10.1?3.0) minutes, shorter significantly than that of KA and CSF+KA groups (0.010.05). The mean stage of ?-FNA + KA group was 1.7?0.1, being reduced significantly as compared with the stages of other three groups ( P

Objective:To discuss and analyze the clinical efficacy and application value of transperineal ultrasound dynamic monitoring for the contraction function of pelvic floor muscle to guide training based on its feedback in the treatment of stress incontinence of female.Methods: 169 female patients with stress incontinence were enrolled this study. And all of them were treated by using the Koegel physical training of pelvic floor muscle under the guidance of doctor, at the same time, the relative contraction function indicators of pelvic floor muscle before and after treatment were observed and compared by applied transperineal ultrasound dynamic monitoring.Results: The differences between before and after treatment of physical training on pelvic floor muscle about the length of the levator hiatus, the acreage of pelvic diaphragm hiatus, and the perimeter of pelvic diaphragm hiatus in contraction and silent period were significant (t=-2.858,t=-2.949,t=-4.899,P<0.05), and that of after treatment was higher than that of before treatment. The horizontal distance of pubis combined with margo inferior, vertical distance and thickness of viscera on pubis of after treatment were significant higher than that of before treatment (t=3.674, t=-4.899,t=4.230,P<0.05). The posterior urethra intersection angle and the intersection angle of left and right levator after treatment were significantly higher than that of before treatment (t=-4.087,t=6.584, P<0.05).Conclusion: Transperineal ultrasound dynamic monitoring can correctly evaluate the clinical efficacy of the contraction function of pelvic floor muscle to guide training based on its feedback in the treatment of stress incontinence of female. And this method has important clinical value.

Objective:To explore influence of percutaneous coronary intervention (PCI)on brain natriuretic peptide (BNP)level and ventricular remodeling in patients With acute ST elevation myocardial infarction (STEMI).Meth-ods:According to their therapeutic methods,a total of 151 patients diagnosed as STEMI Were divided into group A (n=52,received emergency PCI treatment),group B (n=49,received selective PCI treatment)and group C (n=50,received standard medication).BNP level and left ventricular remodeling Were compared among three groups before treatment and after treatment.Results:There Was no significant difference in BNP level among three groups before treatment (F=0.01,P>0.05),BNP level significantly decreased among three groups after treatment,com-pared With group B and C,there Was significant decrease in BNP level [(466.2±113.5)ng/L vs.(601.4±126.7) ng/L vs.(242.7±101.3)ng/L]in group A (P<0.01 all).There Were no significant difference in left ventricular end-diastolic volume (LVEDV),left ventricular end-systolic volume (LVESV),left ventricular ejection fraction (LVEF)and left ventricular fractional shortening (LVFS)among three groups before treatment (P>0.05 all);af-ter treatment,there Were significant increase in above ventricular indexes in three groups (P<0.05 all),compared With group C,there Were significant increase in LVFS [(22.6±6.9)% vs.(28.9±7.6)% vs.(27.5±7.3)%]in group A and B,compared With group B and C,there Was significant increase in LVEF [(53.1±6.5)% vs.(50.9± 5.7)% vs.(57.9±6.2)%]in group A (P<0.01 all).Conclusion:PCI could effectively improve ventricular re-modeling and decrease BNP level in STEMI patients,and emergency PCI shoWs more significant therapeutic effects than selective PCI.

To explore the changes of anti-thyroid drug (ATD) on bone mineral density and bone turnover parameters in patients with Graves disease (GD).Compared with the healthy controls during the same period,the serum levels of alkaline phosphatase (AKP) and bone gla protein (BGP) in GD patients significantly increased at pre-treatment and after normal thyroid by treatment (P ＜ 0.05,P ＜ 0.01).AKP and BGP of GD patients reduced to normal level at Month 6 after normal thyroid (P ＞ 0.05) ; BMD significantly decreased at pre-treatment and Month 12 after normal thyroid (P ＜ 0.05,P ＜ 0.01).And it dropped to normal level at Month 18 (P ＞ 0.05).GD could affect bone metabolism and thyroid hormone might accelerate bone metabolism directly.

AIM: To investigate the mRNA changes of L-type Ca~(2+) channel ?_(1C) subunit (CaL-?_(1C)) and Na~+-Ca~(2+) exchanger (NCX) in the atria of renovascular hypertensive rats. METHODS: Two-kidney one-clip Goldblatt hypertensive Sprague-Dawley rats were divided into three groups 1 week after operation, HD group was treated with 250 mg/d diltiazem, LD group was treated with 50 mg/d diltiazem, control group (C group) was treated with vehicle. After 4 weeks treatment, semiquantitative RT-PCR was used to estimate the mRNA changes of CaL-?_(1C) and NCX, and GAPDH was used as internal control. RESULTS: Systolic blood pressure in LD group was comparable with C group, and that in HD group was decreased to normal level after diltiazem treatment. In C group, CaL-?_(1C) mRNA level were 2.5, 2.4 and 2.1 times of S, HD and LD group, and NCX mRNA level were 1.9, 1.6 and 2.1 times of S, HD and LD group. There were no significant difference in the mRNA level of CaL-?_(1C) and NCX among S, HD and LD group. CONCLUSION: The mRNA levels of CaL-?_(1C) and NCX are upregulated in the atria of hypertensive rats. Ca~(2+) antagonist inhibits their upregulation independent of blood pressure.

BACKGROUND:Titanium ions have been proved to stimulate the secretion of bone remodeling-related factors from T lymphocytes;however, the effects of titanium ions on the early activation, intermediate activation, and cel cycle of T lymphocytes remain unclear. OBJECTIVE:To investigate the effects of titanium ions on the proliferation and activation of T lymphocytes in vitro. METHODS:Cel proliferation and cycle test:Jurkat E6-1 T lymphocytes in logarithmic phase were col ected and cultured in the medium containing 0 (control), 25 (low concentration), 50 (middle concentration), and 100μmol/L (high concentration) titanium ions for 24 hours to detect the cel relative proliferation rate and cel cycle. Cel activation trial:Jurkat E6-1 T lymphocytes were divided into two groups that were subdivided into four groups containing 0, 25, 50, and 100μmol/L titanium ions, respectively with or without phytohemagglutinin (PHA) pre-stimulation. The expressions of CD69 and CD25 were measured after cultured for 24 hours. RESULTS AND CONCLUSION:Titanium ions enhanced T lymphocytes proliferation in a concentration-dependent manner (P<0.05). Compared with the control group, the percentages of G0/G1 phase decreased and the proportions of cel s in S and G2/M phase increased significantly in the low, middle and high concentration groups (P<0.05). The proportion of G0/G1-phase cel s in the high concentration group was less and the proportion of G2/M phase cel s was higher than those in the middle and low concentration groups (P<0.05). With PHA pre-stimulation, the expression of CD69 in the high concentration group was higher than that in the middle and low concentration groups (P<0.05);whereas the difference of CD25 expression was not significant among four subgroups. Titanium ions promoted the expression of CD69 in a concentration-dependent manner (P<0.05), but there was no CD25 expression in each subgroup without PHA pre-stimulation. To conclude, titanium ions can significantly promote T lymphocyte proliferation and early activation in vitro, and moreover, induce S and G2/M phase arrest in T lymphocytes.
