Objective To observe the effect of vinpocetine on monoamine transmitters in cerebral of poststroke depression (PSD)rats and to investigate the mechanism of pharmacotherapeutics on PSD. Methods Rats were divided randomly into the sham-operated group,the normal saline group,the low dose of vinpocetine group and the high dose of vinpocetine group. Giving the left middle cerebral artery occlusion, the PSD rat model was established by unexpected chronic mild stress. When the PSD rat model was established, vinpocetine group was given vinpocetine(5mg/kg, 10mg/kg) and the normal saline group was given normal saline. Then the ethological score of depression was evaluated on 14 and 28 days. The monoamine transmitter in the frontal cortex and hippocampus and brainstem were detected by the fluorospectrophotometry. Results On the 28th day after the model establishment,compared with the normal saline group, the ethological score of depression level was decreased obviously. Compared with the normal saline group, vinpocetine could improve the ethological score of depression level of the PSD rat model, and these concentrations of 5-hydoxytrypatarmine ( 5-HT), noradrenalin ( NE ) and dopamine ( DA ) in the frontal cortex, hippocampus and brainstem. The level of NE ( ( 192.4 ± 34.8 ) ng/g, ( 206. 0 ± 41.7 ) ng/g,(91.1 ±23.0) ng/g] ,5-HT( (494. 1 ± 50.7) ng/g, (599.7 ± 39.2) ng/g, (541.7 ± 62.6) ng/g) and DA ( ( 298.6 ± 32.6) ng/g, ( 297.0 ± 38.1 ) ng/g, ( 85.9 ± 24.3 ) ng/g) in the high dose of vinpocetine group were significantly higher than that in the normal saline group ( NE (92.4 ± 17.5 ) ng/g, ( 131.4 ± 34.8 ) ng/g, (49.0 ±13.6)ng/g;5-HT(367.8 ±87.3) ng/g,(498.7 ± 79.6) ng/g, (320.4 ±59.4) ng/g; DA( 106.1 ±23.0)ng/g,(97.0 ±21.7)ng/g, (50.4 ± 13.8 )ng/g)(P < 0.01 ). There were increased obviously by the high dose than the low dose of vinpocetine group. Conclusion Vinpocetine could treat PSD by increasing the level of monoamine transmitters in PSD rats' brain.

Objective:To evaluate the efficacy of transcatheter arterial embolization with detachable balloon for pulmonary arteriovenous fistula(PAVF). Methods: A 48 year old female with PAVF suffered intermittent emoptysis, fatigability, exertional dyspnea, and palpitations. CT and MRI demonstrated 2 PAVF in the module lobe on right side. Pre embolization super selective pulmonary angiography revealed 2 fistulae communicating to the sac of the lesion.Three detachable balloons were used for embolization of the feeding arterial branch.The diameter of detachable balloons was twice as that of the feeding arterial branch. The study of blood gases showed the arterial oxygen pressure was 6.5 kPa before operation, hemoglobin at 158 g/L. Results: No complications were apparent in our case. Two PAVF were completely occuluded by the embolization of a feeding branch. One month later, the arterial oxygen pressure increased to normal values, hemoglobin at 125 g/L and clinical symptoms disappeared. On postcontrast CT, the fistulas treated by the embolization of a feeding arterial branch were not enhanced. No symptoms and signs were found in follow up for 16 months. Conclusion: The percutaneous transcatheter embolization with detachable balloon is effective for PAVF. [

Objective:To construct the Helicobacter pylori infected C57BL/6 mice model to observe the activation of NOD1/NF-κB signaling pathways in the gastric tissues,and study its roles in inflammatory response during Hp infection.Methods:6-8 week-old C57BL/6 mice were randomly divided into two groups,the Hp infection group and the control group,and mice were given by gavage every 48 h for five times with Hp or PBS,respectively.All the animals were sacrificed at different time point and the gastric tissue were stained with hematoxylin-eosin( HE);The mRNA expression of NOD1 and RIP2 in gastric tissues were examined by RT-PCR;Levels of IFN-βand IP-10 in mice serum were assessed by ELISA;Nuclear translocation of p65 in gastric tissue was detected by Western blot.Results:Hp infection elicits an inflammatory cell response,glands in gastric tissue were reduced or atrophic,as compared with that in the control group.The levels of IP-10 and IFN-βincreased in the model group, and peaked at 16 weeks after Hp infection.Hp infection increased the mRNA expression of NOD1 and the p65 content in nuclear between 24-120 h(P<0.05),and the highest level at 48 h,subsequently the expression levels were began to decrease.The mRNA expression level of RIP2 was up-regulated after Hp was administrated, peaked at 48 h and declined after 72 h.However, the expression levels would rise again at 120 h.Conclusion: Hp infection can activate the NOD1/NF-κB signaling pathways and induce the production of IFN-βand IP-10 in gastrics of mice.

To develop a LC-MS/MS method for the determination of protocatechuic acid, protocatechuic aldehyde, salvianolic acid A, salvianolic acid B, cryptotanshinone and tanshinone II(A) in rat plasma and brain. The plasma and brain samples were precipitated with ethyl acetate, then were separated on an Agilent eclipse plus-C18 column (2.1 mm x 50 mm, 3.5 microm) using acetonitrile (consisting of 0.1% formic acid) and water (consisting of 0.1% formic acid) as mobile phase in gradient elution mode. The mass spectrometer was operated under both positive and negative ion mode with the ESI source, and the detection was performed by MRM. The transition of 154.3/153.1 m/z for protocatechuic acid, 137.3/108 m/z for protocatechuic aldehyde, 493.0/295.2 m/z for Salvianolic acid A, 718.0/520.0 m/z for salvianolic acid B, 321.4/152.3 m/z for chloramphenicol, 297.4/254.3 m/z for cryptotanshinone, 295.5/249.3 m/z for tanshinone II(A) and 285.2/154.0 m/z for Diazepam. The calibration curves in the range of 0.625-1 000 microg x L(-1) for protocatechuic acid and protocatechuic aldehyde, 1.25-1 000 microg x L(-1) for salvianolic acid A, 2.5-1 000 microg x L(-1) for salvianolic acid B, 0.15-1 000 microg x L(-1) for cryptotanshinone, 0.625-1 000 microg x L(-1) for tanshinone II(A) are with good linearityin rat plasma and brain. The analysis method is sensitive, simple, and suitable enough to be applied in the pharmacokinetic study of the 6 main components. Animal testing gives the lgBB of the drugs and further studies of the 6 components cross the blood-brain barrier can be carried out.

Transient receptor potential vanilloid 1 (TRPV1) is a non-selective positive ion channel that is mainly expressed in sensory neurons and a member of transient receptor potential (TRP) family. The receptor could be activated by mechanical irritation, chemical irritation or endogenous ligand to mediate pains and cause injury to body functions. Traditional Chinese medicine believes that the mechanism of pain is that "stagnation leads to pain". Specifically, both of the contracture and tautness caused by cold and the blood stasis could result in blood impassability and pain. Most of traditional Chinese medicines for clearing heat and removing toxicity have the anti-inflammatory effect, while those for warming interior, and promoting blood circulation to remove blood stasis have the effect in smoothening blood vessels. Therefore, either with the anti-inflammatory effect or the effect in smoothening blood vessels, traditional Chinese medicines for clearing heat and removing toxicity, warming interior, and promoting blood circulation have the analgesic effect In this paper, the authors summarize the analgesic effect of the above three traditional Chinese medicines, with TRPV1 as the target.
