To observe the effect of electro-acupuncture on the relapse to heroin-seeking induced by heroin-related cues after withdrawal from heroin self-administration in rats.Methods:Sixty male Wistar rats were randomized into physiological saline group,withdrawal group A,withdrawal group B,electro-acupuncture(EA)treatment group A and EA treatment group B,with 12 rats in each group.The rats were trained by nose-poke response to self administer heroin (50 μg/kg/per infusion) or saline with one daily 4-h session for 14 consecutive days,the session ended after 25 infusions were eamed or 4 hours had passed,the reinforcement schedule was a progressive ratio.Then rats in withdrawal group A and withdrawal group B were withdrawn from heroin for 1 week and 2 weeks respectively,and then they were reintroduced to their training chambers for 4-h relapse testing which was induced by heroin-related environmental cues;And rats in EA treatment group A and EA treatment group B were also withdrawn from heroin for 1 week and 2 weeks respectively,during which they were given EA treatment for 20 min daily,then they received relapse testing;In the meantime,rats in saline group were trained with saline instead of heroin for 14 days as control.after 7 days of withdrawal from saline,they received relapse testing.Results:Following 7-8 days of drug training,the rats began to establish the stable intravenous heroin self-administration behavior;For the stable heroin self-administrating rats that received EA treatment,when they were reintroduced to their training chambers,their heroin-seeking behaviors were obviously inhibited,and this inhibitory effect related to the cumulativeness of EA stimulation.Conclusion:The results suggested that EA could prevent relapse to heroin-seeking to a certain extent.

Objective To investigate the changes of serum homocysteine ( Hcy),C-reactive protein ( hsCRP) levels in acute cerebral infarction patients and its significance.Methods 64 patients with acute cerebral infarction were selected as research group,and 60 healthy volunteers were selected as control group.Detected the acute cerebral infarction patients after 1d,the first 7d,14d Hcy,hs-CRP,total cholesterol,triglycerides,high density lipoprotein,low density lipoprotein levels and the control group the level of these indicators.Results Of total cholesterol,triglycerides,low density lipoprotein of the study group was higher than those of the control group of high-density lipoprotein(t =3.073,2.874,2.015,all P <0.05);after admission ld,treatment of the first 7d,14d showed no significant difference between the two groups ( t =2.223,2.268,all P < 0.05 ).Conclusion Hcy,hs-CRP and the occurrence of acute cerebralinfarction was closely related to the development,and testing to determine the severity of the disease for the guide had important clinical significance.

Objective: This present study is to investigate the biochemical adaptations in the related brain regions of the mesolimbic dopamine system, such as the ventral tegrnental area (VTA), nucleus accumbens (Nac), amygdale (Amy), prefrontal cortex (PFC) , substantia nigra (SN) and caudateputamen (Cpu) in response to heroin self-administration in rats and observe the effect of electroacupuncture on them. Methods: 2hirty rats were trained by nose-poking response to establish stable intravenous heroin self-administration within 14 days, and then divided randomly into model group (group B) including 6 rats, withdrawal group which were withdrawn from heroin for 1 week (group C, n = 6) and for 2 weeks (group D, n= 6), during which time they only lived in their individual home cages,and electro-acupuncture group which were also withdrawn from heroin for 1 week (group E, n= 6) and for 2 weeks (group F, n= 6), during which time they were given electro-acupuncture treatment for 20 min daily and then returned to their individual home cages; in the meantime, another 6 rats were trained by nose-poking response with saline for 14 days as control (group A); Then the levels of tyrosine hydroxylase (TH) and glial fibrillary acidic protein (GFAP) in VTA, Nac, Amy, PFC, SN, Cpu were detected with immunohistochemistry method. Results: The leveks of TH and GFAP in VTA of the heroin self-administrating rats were obviously increased, and the levels of TH and GFAP in Nac were also decreased, and these changes were not found in SN, Cpu, Amy and PFC; Electro-acupuncture could promote the up-regulation of TH and GFAP in VTA and down-regulation of TH and GFAP in Nac to return to the normal level. Conclusions: The chronic heroin self-administration produced some biochemical adaptations in the rdated brain regions of the mesolimbic dopamine system and electroacupuncture could promote the repair of the injured DA neurons in VTA of heroin addicted rats and their functional recovery.

Objective To observe the effects of Angong Niuhuang Bolus(ANB) on vital organ injury and mortality in rats with sepsis.Methods SD rats were randomized into normal control group,model group,and low-,middle-and high-dose ANB groups(in the dose of 1.0,2.0 and 3.0 g?kg-1?d-1 respectively).Except that the normal control group,the rats in other groups received cecal ligation and puncture(CLP) method to induce sepsis through abdominal infection.ANB groups were given gastric gavage of ANB 0.5 hours before CLP and 6 hours after CLP.After CLP for 24 hours,the mortality was observed,serum levels of alanine aminotransferase(ALT),total bilirubin(TB) and creatinine were detected,and pulmonary myeloperoxidase(MPO) activity in all of the rats was examined.Results Serum ALT and TB levels,MAO activity and 24-hour mortality were increased in the model group(P

Objective To investigate the effect of Angong Niuhuang Bolus(ANB) on mRNA expression of high mobility group box-1(HMGB1) protein and myeloperoxidase activity in the lung of rats with sepsis induced by cecal ligation and puncture(CLP) method.Methods Seventy-five male SD rats were randomly divided into normal control group,model group,AG490(a Janusk kinase inhibitor) treatment group(subcutaneous injection of AG490 8mg/kg 0.5 h before CLP),rapamycin(RPM,a signal transduction and transcription activator inhibitor) treatment group(subcutaneous injection of RPM 0.4 mg/kg 0.5 h before CLP),and low-,middle-and high-dose ANB groups(gastric gavage of ANB in the dose of 1.0,2.0 and 3.0 g?kg-1?d-1 respectively).The animals were sacrificed 24h after CLP,and then lung tissue samples were collected to determine the expression of HMGB1 mRNA by the method of reverse transcription polymerase chain reaction(RT-PCR).Meanwhile,the activity of pulmonary myeloperoxidase(MPO) was also measured.Results Compared with the normal control group,the mRNA expression of HMGB1 was significantly enhanced(P

Objective To explore the expression of tissue inhibitor of metalloproteinases-2(TIMP-2) in peripheral blood lymphocytes in patients with chronic obstructive pulmonary diseases(COPD) and the association of smoking and TIMP-2 mRNA. Methods The expression of TIMP-2 mRNA in peripheral blood lymphocytes was measured by reverse transcription-polymerase chain reaction(RT-PCR) in 44 patients with COPD and 42 healthy smokers.The correlation analysis was then conducted between TIMP-2 mRNA expression and smoking index. Results The expression of TIMP-2 mRNA was 0.753?0.154 and 1.170?0.196,respectively,in patients with COPD and healthy smokers(P

ObjectiveTo study the features of lower limb vein thrombus patients after spinal cord injury and the effects of thrombolysis therapy.MethodsWe practiced ultrasonography on 207 patients with lower limb swelling after spinal cord injury. ResultsAmong the 207 patients, 66 had thrombus, the positive rate was 31%: acute thrombus 58 cases, subacute thrombus 1 cases and chronic thrombus 7 cases. Conclusions Ultrasonography provides an important basis for the qualitative diagnoses of lower limb vein thrombus. It has certain clinical guiding effects in choosing methods of treatment.
