OBJECTIVETo observe the effects of amitrole on the transcription of thyroglobulin (tg), thyroid peroxidase (tpo), Na(+)/I- symporter (nis), Na(+)/I- symporter (nis), thyroid-stimulating hormone receptor (tshr), thyroid transcription factor 1 (ttf-1) and paired-domain protein-8 (pax-8) genes in FRTL-5 cells and investigate the mechanism of amitrole for intervening in thyroid hormone activity.
METHODSFRTL-5 cells were treated with amitrole at 0.001, 0.01 and 0.1 mg/ml for 24 h, respectively, after which the cells were collected for extraction of the total RNA. RT-PCR was used to examine the effects of amitrole on the transcription of tg, tpo, nis, tshr, pax-8 and ttf-1 genes in FRTL-5 cells.
RESULTSAmitrole significantly induced tg gene transcription at all the doses, but produced no obvious effects on tpo and nis gene transcription. At the concentration of 0.1 mg/ml, amitrole significantly reduced pax-8 and tshr gene transcription but increased ttf-1 gene transcription.
CONCLUSIONThe effects of amitrole on thyroid hormone activity may be related with its actions on tg, ttf-1, tshr and pax-8 gene transcription.

BACKGROUNDBrain-derived neurotrophic factor (BDNF) is a stress-responsive intercellular messenger modifying hypothalamic-pituitary-adrenal (HPA) axis activity. The interaction between stress and age in BDNF expression is currently not fully understood. This study was conducted to observe unpredictable stress effect on behavior and BDNF expression in CA3 subfield (CA3) and dentate gyrus of hippocampus in different aged rats.
METHODSForty-eight Wistar rats of two different ages (2 months and 15 months) were randomly assigned to six groups: two control groups and four stress groups. The rats in the stress group received three weeks of unpredictable mild stress. The depression state and the stress level of the animals were determined by sucrose preference test and observation of exploratory behavior in an open field (OF) test. The expressions of BDNF in CA3 and dentate gyrus of the hippocampus were measured using immunohistochemistry.
RESULTSAge and stress had different effects on the behavior of different aged animals (age: F = 6.173, P < 0.05, stress: F = 6.056, P < 0.05). Stress was the main factor affecting sucrose preference (F = 123.608, P < 0.05). Decreased sucrose preference and suppressed behavior emerged directly following stress, lasting to at least the eighth day after stress in young animals (P < 0.05). The older stress rats showed a lower sucrose preference than young stress rats (P < 0.05). Older control rats behaved differently from the younger control animals in the OF test, spending more time in the central square (P < 0.05), exhibiting fewer vertical movements (P < 0.05) and less grooming (P < 0.05). Following exposure to stress, older-aged rats showed no obvious changes in vertical movement and grooming. This indicates that aged rats were in an unexcited state before the stress period, and responded less to stressful stimuli than younger rats. There was significantly lower BDNF expression in the CA3 and dentate gyrus regions of the hippocampus following stress in both age groups (P < 0.05), a reduction that was still present at the eighth day after stress (P < 0.05). Stress and age were the main factors affecting the expression of BDNF (F = 9.408, P < 0.05; F = 106.303, P < 0.05). The aged stress group showed lower BDNF expression compared to the young stressed group at every testing time point.
CONCLUSIONStress has age-dependent effects on behavioral responses and hippocampal BDNF expression in rats.

OBJECTIVETo observe the effect of acupoint sticking on clinical symptoms and life quality in patients with bronchial asthma.
METHODSMulticenter randomized double-blind clinical trial was done, one hundred and eighty-eight cases were divided into a medication acupoint sticking group (125 cases) and a placebo group (63 cases). Dazhui (GV 14), Feishu (BL 13), Tiantu (CV 22), etc. were selected in both groups. The medication cakes were made of grinding pepper, brassica alba seeds, asarum, etc. into fine powder mixed with ginger oil and ginger juice, applied on acupoints in the acupoint sticking group. While another compound cakes made of powder of red rice, black rice, maize mixed with small amount of ginger juice, were used in the placebo group. Asthma Quality of Life Questionnaire(AQLQ), symptom scores during the day and night, scores of self effect, and the value of lung function were observed.
RESULTSThe value of daily behavior and environmental factors of AQLQ, total scores of AQLQ, daytime symptoms and scores of self effect in the medication acupoint sticking group, were significantly improved compared to those of placebo group (all P<0.05). The lung function of forced expiratory volume in one second (FEV1) and the percentage of forced expiratory volume in one second in predicted value (FEV1/FVC) had no significant diffrence between two groups (both P>0.05).
CONCLUSIONThe acupoint sticking therapy can significantly improve clinical symptoms of patients with bronchial asthma, and can improve life quality of the patients.

AIMTo investigate the protective effect of lumbrokinase against myocardial ischemia and to further explore its underlying mechanisms.
METHODSThe effect of lumbrokinase on myocardial ischemia was observed by a model of acute myocardial infarction due to permanent ligation of the left anterior descending coronary artery in rats. Patch-clamp technique and laser scanning confocal microscopy were utilized to study the action of lumbrokinase on L-type calcium current (ICa-L) and intracellular calcium concentration ([Ca2+]i).
RESULTSLumbrokinase decreased the infarct size of myocardium in a dose-dependent manner. The inhibitory rate of lumbrokinase at the dose of 20, 40 and 80 mg x kg(-1) was 7.7%, 34.6% and 46.2%, respectively. The electrophysiological studies displayed that, at + 10 mV, the ICa-L was markedly reduced from (-14.42 +/- 1.53) pA/pF to (-11.33 +/- 1.40) pA/pF (decreased by 21.4%, P <0.01) and (-9.92 +/- 1.31) pA/pF (decreased by 36.5%, P <0.01) by lumbrokinase (10 and 50 micromol x L(-1)), respectively. Confocal experiments showed that 10 micromol x L(-1) lumbrokinase showed no obvious effects on [Ca2+]i at resting states (P > 0.05). However, the increase of [Ca2+]i induced by 60 mmol x L(-1) KCl was distinctly limited by 10 micromol x L(-1) lumbrokinase (P <0.01). Within 240 s, the no obvious peak value of fluorescent intensity (FI) was shown.
CONCLUSIONLumbrokinase showed protective action against myocardial infarction in rats. The possible mechanisms of anti-ischemia could be attributed to decreasing ICa-L and [Ca2+] of ventricular myocytes in rats.
