The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

OBJECTIVETo observe the pregnancy outcome among patients with chronic myelogenous leukemia (CML) treated with tyrosine kinase inhibitors (TKIs).
METHODSData associated with pregnancy, delivery and neonate from the patients or patient's spouse who conceived while receiving TKIs were collected retrospectively.
RESULTSTwo young female patients (who had been on imatinib therapy for 90 and 91 months, respectively) and spouses of 10 male patients (involving 7 patients who had received imatinib for a median of 60 months and 3 who had received dasatinib for 2.5 months to 7 months, respectively) with median age of 33.5 years (range 26 - 46 years) conceived and gave birth to 12 babies. One woman took imatinib throughout her pregnancy except one month. The other one took imatinib throughout her pregnancy and had breast-fed while on imatinib therapy for nearly half a year postpartum. Among the 12 babies, one was born prematurely with low birth weight and hypospadias (surgical repair after birth), the others were all healthy with no congenital defects. The median age of the children at the date of this report is 17.5 months (range 3 to 101 months), and they all have a normal pattern of growth and development.
CONCLUSIONSConception among patients with CML while receiving TKIs may result in normal pregnancies. The possible effects of TKIs on birth abnormalities cannot be ruled out. It is recommended that childbearing female patients should be advised to practice adequate methods of contraception and should not breast-feed while on TKIs therapy. In cases of accidental pregnancy, risk/benefit evaluations must be carried out carefully on an individual basis. No special precautions apply for male patients being treated with imatinib.

OBJECTIVETo investigate the acute effects of aldosterone (ALD) on mesenteric resistance vessels in normal or heart failure (HF) rats and its mechanism.
METHODSHF model was adopted by in vivo ligation of left anterior descending coronary artery in SD rats; segments of third-order branches of mesenteric artery were isolated and dissected into about 2 mm rings for isometric force recording.
RESULTSPretreated with ALD for 10 min,phenylephrine (PE)-induced contraction of normal mesenteric artery decreased first and then increased compared to control group along with the increase of the concentration of PE while decreased in HF rats. This effect was attenuated by ALD receptor-special antagonist eplerenone partially. ALD increased Ach-induced endothelial-dependent vascular relaxation significantly compared to control group both in normal and HF rats. Pretreated with ALD and dexamethasone (DEX) for 10 min, the effects of ALD on PE-induced contraction were weakened in mesenteric artery both of normal and HF rats. And this reaction of DEX to ALD-treated mesenteric in normal rats was attenuated by RU486 partially.
CONCLUSIONALD has biphasic effect in PE-induced response on mesenteric artery of normal rats, while reduces the sensitivity of mesenteric artery to PE in HF rats. DEX attenuates the biphasic effect of ALD on artery of normal rat partially but has no significant effect on that of HF rats.

OBJECTIVETo investigate the expression of motilin-immunoreactive neurons in the hypothalamus and the effect of central administration of erythromycin (EM) on the regulation of gastric motility in diabetic rats.
METHODSThe motilin immunoreactive neurons in the hypothalamus and the hippocampus were detected by immunohistochemistry with rabbit anti-motilin polyclonal antibody. To measure the gastric motility, force transducers were surgically affixed to the gastric serosa. A microinjection syringe was connected via a plastic tube to an injection cannula, which was connected with a stainless steel guide cannula. The syringe was inserted into the right lateral cerebral ventricle for microinjecting the chemicals.
RESULTSDiabetic mellitus was successfully induced in cohorts of rats. Motilin-immunoreactive neurons significantly increased in the paraventricular (PVN) and supraoptic nuclei (SON) of the hypothalamus in the diabetic rats. Intracerebroventricular (i.c.v.) administration of EM, a motilin receptor agonist, stimulated the gastric motility of diabetic rats. EM (91.56 nmol, i.c.v.) dose-dependently increased the amplitude by (174.82 +/- 48.62)% (P<0.05), and increased the frequency by (70.43 +/- 27.11)% (P < 0.05) in 5 min. The stimulatory effect lasted more than 15 min to the end of the measurement, and can be blocked partially by the prior treatment of motilin receptor antagonist GM-109.
CONCLUSIONMotilin-immunoreactive neurons are increased in the PVN and SON of the hypothalamus in diabetic rats. Centrally administered EM may regulate gastric motility by binding to the central motilin receptors, and central motilin might be involved in regulation of gastric motility in diabetic rats.
