Effects of acupuncture on spontaneous discharges of nerve cells in ventromedial neucleus of hypothalamus (VNH) and levels of monoamine neurotransmitters in rats of obesity were observed. Results indicated that levels of tyrosine (Tyr) and dopamine f DA) were decreased, and the levels of 5 -hydroxytryptamine (5 - HT) and 5 - hydroxyindole acetic acid (5 - HIAA) increased in VNH; The frequency of spontaneous discharges of nerve cells in VNH lowered significantly in the obesity group as compared with those in the normal group; When acupuncture attained effect of weight reduction, the frequency of spontaneous discharges of nerve cells in the VMH increased obviously; the levels of Tyr, DA, tryptamine , and 5 - HT/5 - HIAA increased, and 5 - HT level decreased in VMH tissue. It is suggested that the benign regulative action of acupuncture on VNH is possibly one of the crucial factors for acupuncture in reducing body weight.

BACKGROUND:Many studies have demonstrated that FirebirdTM and Taxus Express2TM can effectively reduce intrastent restenosis.However,there are few data about long-term efficacy of two stents,and reports about middle and long-term follow up are rare.OBJECTIVE:To observe the safety and biocompatibility of FirebirdTM and Taxus Express2TM in percutaneous coronary intervention(PCI) for coronary artery disease.DESIGN,TIME AND SETTING:Non-randomized concurrent control clinical observation was performed at Department of Cardiology,Hongqi Hospital of Mudanjiang Medical College from April 2005 to April 2008.PARTICIPANTS:233 patients(268 lesions) undergoing PCI were divided into FirebirdTM(n =82),Taxus Express2TM group(n =80) and bare metal stent group(n =71).METHODS:Coronary arteriography was performed through femoral artery or radial artery.Vascular inner diameter was determined using quantitative computer analysis.The patients underwent FirebirdTM,Taxus Express2TM and bare metal stenting,respectively.The patients were reexamined and followed-up using telephone every 2-4 weeks after discharging and examined using coronary arteriongraphy after 9-12 months.The follow-up lasted for 24 months.MAIN OUTCOME MEASURES:Characteristics of arteriongraphy and stenting condition of all patients;biocompatibility of stent to host;major adverse cardiac events during hospitalization and follow-up,including death,angina pectoris attacks or heart failure;coronary artery diameter decreased ≥ 50% was regarded as restenosis.RESULTS:101 stents were implanted in Firebird group,98 in Taxus Express2 group and 85 in bare metal stent group.There was no stent defluxion,dislocation,or breakage.No noticeable platelet decrease,hemolysis or white blood cell increase was found.There were no significant differences among three groups in terms of Characteristics of arteriongraphy and stenting condition.The incidence of major adverse cardiac events and intravascular restenosis in Firebird and Taxus Express2 groups was fewer than bare metal stent group(P 0.05).CONCLUSION:No specific biocompatibility responses in treatment of coronary artery diseases using FirebirdTM and Taxus Express2TM.The two drug-eluting stents are superior over bare metal stent in reducing restenosis.The safety and efficacy of two drug-eluting stents are similar.

Objective To investigate the cause and countermeasures of frequent shocks in patients with implantable cardioverter defibrillators (ICD). Methods Eighty ICD patients with heart failure and malignant ventricular arrhythmias were followed up, including sixty-two male and eighteen female patients. There were 35 patients with single-chamber ICD, 23 with dual-chamber ICD and 22 with three-chamber ICD. Patients in this study were followed up for 1-6 years to analyze the reasons for ICD discharge. According to the specific circumstances, patients were treated. Results Twenty-three pa-tients in 80 patients suffered from shock treatment. Ten patients (12.5%) experienced frequent shocks. The causes of fre-quent shock included repeated episodes of ventricular tachycardia, invalid shock due to increased defibrillation threshold (DF) and false identification of the frequent episodes of paroxysmal ventricular tachycardia or arrhythmias. The management included the identification process adjustment of ventricular tachycardia and supraventricular tachycardia, increased num-bers of beats of ventricular tachycardia judgment and increase the basic pacing rate. The anti-arrhythmic drugs should be combinedly used, especially metoprolol and amiodarone. The ICD shock was significantly reduced after parameter optimiza-tion and anti-arrhythmic therapy. Conclusion The ICD shocks were effectively reduced with rational use of anti-arrhyth-mic drugs and valid ICD programming.

Neutrophil extracellular traps (NETs) are fibrous structures released by neutrophils and the formation process is called NETosis. NETs participate in the host innate immunity. Recent research has found that NETs is a double-edged sword. Under normal conditions, the formation of NETs can play a role in clearing pathogens and maintain the host homeostasis. However, when NETs are overproduced or not cleared in time, they can take part in the pathogenesis of many diseases. This article reviewed the formation of NETs, the mechanisms involved in NETosis and the role of NETs in the secretion of multiple cytokines in different diseases.

Objective To study the characteristic of ultra-rapid delayed rectifier-potassium channel K current (IKur) in rat isolated atrial myocytes using whole-cell patch clamp technique, and the effect of Ibulitide on rat isolated atrial myocytes. Methods Atrial myocytes of rats on an in vitro Langendorf perfusion system were obtained by double digestion (collagenase typeⅡ) method. Whole-cell patch-clamp recording technique was used to record IKur currents. The current-voltage (I-V) curves of K+currents of atrial myocytes were fitted. With filled Ibulitide (2μg/L, filled 3 minutes), IKur was recorded. Results The Results showed that IKur was activated rapidly, almost no lag,and deactivation slowly. This current was activated at about-20 mV, the peak current was present apparent voltage dependence. The peak current density was (2.01 ± 0.27) pA/pF. After filled with Ibulite, this current was no any changed activation. Ibulite decreased the peak current density from+30 mV to+50 mV,but no statistical significance. Conclusion The IKur of rats can activate rapidly with no delays and inactivate slowly. This current is ultra-rapid delayed rectify outside current,and obvious displays the characteristic of outward rectification of whole action potential duration. The 2 μg/L Ibulitide shows no statistical significance for this current.

Objective To retrospectively analyze the treatment outcomes and prognostic factors for primary bone lymphomas ( PBL) . Methods Forty patients with PBL who were admitted to our center from 1964 to 2014 were enrolled as subjects. In those patients, 10 were treated with chemotherapy alone, 10 with radiochemotherapy, 10 with postoperative chemotherapy, 9 with postoperative radiochemotherapy, and 1 with surgery alone. The median radiation dose was 36 Gy. The Kaplan?Meier method was used to calculate survival rates . The log?rank test was used for survival difference analysis and univariate prognostic analysis . Results The follow?up rate was 100%. The 3?year sample size was 36. In all patients, the 1?and 3?year overall survival rates were 60% and 42%, respectively, while the 1?and 3?year disease?free survival rates were 45%and 34%, respectively. The univariate analysis showed that no pathological fracture at diagnosis, normal lactate dehydrogenase level, an International Prognostic Index score of ≤1, early clinical stage ( stageⅠE ) , complete response after initial treatment, no less than 6 cycles of chemotherapy, a radiation dose of≥40 Gy, no progression outside radiation field after radiotherapy, and grade<3 bone marrow suppression during the treatment were prognostic factors for survival ( P=0. 027, 0. 037, 0. 000, 0. 016, 0. 000, 0. 000, 0. 022, 0. 014, and 0. 030). Conclusions The incidence of PBL is low. Comprehensive treatment can achieve satisfactory outcomes. As a PBL staging system, Ann Arbor has limitations. The staging of PBL should be based on local bone destruction and metastasis.
