AIM: To probe into the anti-epilepsy action of artificial Calculus Bovis,by observing its effect on the behavioral of the experimental epileptic rats,neuron loss in the hippocampus and hilus,and GAD positive cell alteration in the hippocampus.METHODS: SD rats were divided into three groups: group A(artificial Calculus Bovis treatment group);group B(acute epilepsy group) and group C(control group).A model of acute epilepsy rats was established by PTZ.The rat's behavioral alteration was observed by the Racine' scale.The neurons in the hippocampus and hilus were calculated by Nissl staining.The GAD positive cells were observed by immunohistochemical staining.RESULTS: The latency of the first seizure in group A was longer than that in group B,while the seizure times in group A was less than that in group B.Besides,in group A,both the neuron loss amount in the hippocampus and hilus and the GAD positive cell loss amount in the hippocampus were less than those in group B.CONCLUSION: The artificial Calculus Bovis prolonged the latency of the first seizure time,decreased the frequency of seizure,and prevented the neuron loss and protected the GAD positive cells.

OBJECTIVETo screen out serum differential proteins between vinyl chloride monomer (VCM)-exposed workers and healthy controls by proteomics and analyze the functions of differential proteins, and to provide a basis for elucidating the pathogenesis of diseases caused by VCM exposure and searching for the protein biomarkers.

METHODSFasting venous blood was collected from 125 VCM-exposed workers and 40 healthy controls according to accumulated exposure doses. Proteins were precipitated by acetone precipitation. These proteins were identified by 2D-nano LC-ESI-TOF/MS and quantified by isobaric tags for relative and absolute quantitation. The functions of differential proteins were analyzed by gene ontology.

RESULTSA total of 596 proteins were identified, including 194 quantified proteins. There were 21 differential proteins according to the screening criteria (19 upregulated proteins and 2 downregulated proteins), including complement, apolipoprotein, and glycoprotein. The functions of these differential proteins were binding, enzyme regulator activity, catalytic activity, and transporter activity, and they were involved in the biological processes including immune system process and response to stimulus.

CONCLUSIONThe complement, apolipoprotein, and glycoprotein identified in the proteomics may be related to liver injury caused by VCM exposure, and they could be used as candidate protein biomarkers of diseases caused by VCM exposure.

OBJECTIVETo investigate whether 3,4-methylenedioxymethamphetamine (MDMA) abuse produces another neurotoxicity which may significantly inhibit the acetylcholinesterase activity and result in severe oxidative damage and liperoxidative damage to MDMA abusers.

METHODS120 MDMA abusers (MA) and 120 healthy volunteers (HV) were enrolled in an independent sample control design, in which the levels of lipoperoxide (LPO) in plasma and erythrocytes as well as the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and acetylcholinesterase (AChE) in erythrocytes were determined by spectrophotometric methods.

RESULTSCompared with the average values of biochemical parameters in the HV group, those of LPO in plasma and erythrocytes in the MA group were significantly increased (P < 0.0001), while those of SOD, CAT, GPX and AChE in erythrocytes in the MA group were significantly decreased (P < 0.0001). The Pearson product-moment correlation analysis between the values of AChE and biochemical parameters in 120 MDMA abusers showed that significant linear negative correlation was present between the activity of AChE and the levels of LPO in plasma and erythrocytes (P < 0.0005-0.0001), while significant linear positive correlation was observed between the activity of AchE and the activities of SOD, CAT and GPX (P < 0.0001). The reliability analysis for the above biochemical parameters reflecting oxidative and lipoperoxidative damages in MDMA abusers suggested that the reliability coefficient (alpha) was 0.8124, and that the standardized item alpha was 0.9453.

CONCLUSIONThe findings in the present study suggest that MDMA abuse can induce another neurotoxicity that significantly inhibits acetylcholinesterase activity and aggravates a series of free radical chain reactions and oxidative stress in the bodies of MDMA abusers, thereby resulting in severe neural, oxidative and lipoperoxidative damages in MDMA abusers.

Cardiomyocyte hypertrophy is a major cause of morbidity and mortality worldwide. The aim of this study is to determine the effects of sodium tanshinone IIA sulfonate (STS) on cardiomyocyte hypertrophy induced by angiotensin II (Ang II) in vivo and in vitro. In long-term treatment, adult Wistar rats were infused with Ang II for three weeks via osmotic mini-pumps and some of them were given intragastrically of STS. Left ventricle was isolated; the ratio of left ventricular weight to body weight and systolic blood pressure (SBP) were determined and heart morphometry was assessed after hematoxylin and eosin staining. Results indicated STS inhibited Ang II-induced increases in myocyte diameter and decreased the LVW/BW ratio independent of decreasing systolic blood pressure. In vitro, treatment of cultured cardiomyocytes with STS inhibited Ang II-induced increase in cell size, protein synthesis, ANP expression, activation of extracellular signal-regulated kinase (ERK) and ERK kinase (MEK). Then we reexamined the mechanism of STS-induced anti-hypertrophic effects. Results revealed MEK inhibitor U0126 (20 microM) markedly enhanced STS-induced depressions in [3H]leucine incorporation and ANP expression. In conclusion, MEK/ERK pathway plays a significant role in the anti-hypertrophic effects of STS.

Ureteral stricture in renal allografts is one of the common postoperative complications in kidney transplant recipients. Due to short ureter in renal allografts, endovascular treatment should be adopted before reconstruction surgery to avoid irreversible injury. Alleviating renal allograft injury, easing obstruction or establishing drainage channel are the key measures to treat ureteral stricture. In endovascular treatment, balloon dilatation and internal incision yield high recurrence rate, and long-term indwelling of self-expanding metallic ureteral stents may be a better option. Compared with traditional stents, metallic stents may maintain urinary tract patency for a long time and mitigate the irritation of lower urinary tract symptoms,with different indications and efficacy. Although all metallic stents may be displaced and occluded, it still plays a positive role in the treatment of ureteral stricture in renal allografts. In this article, the application of self-expanding metallic ureteral stent in ureteral stricture of renal allografts was mainly illustrated, aiming to provide reference for optimizing the treatment of ureteral stricture in renal allografts.
