OBJECTIVETo explore protective effects of acupuncture at "Zusanli" (ST 36) on cerebral tissue in rats with sepsis.

METHODSCecal ligation and puncture (CLP) was applied to duplicate the rat model of sepsis. According to random number table, thirty SD rats were divided into a sepsis model group (group A), a sepsis model plus electroacupuncture (EA) group (group B), and a sepsis model plus non-acupoint EA group (group C), ten rats in each one. EA with the same frequency and intensity at "Zusanli" (ST 36) and non-acupoint (0.5 cm laterally to "Zusanli") for 30 min was applied in the group B and group C, respectively. No treatment was given in the goup A. 6 hours after CLP, blood was acquired from abdominal aorta to measure the levels of neuron specific enolase (NSE). Then the rats were sacrificed by abdominal aorta exsanguination to take their cerebral tissue for measuring the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6).

RESULTSSix hours after CLP, the level of NSE was (3.51 +/- 0.39) ng/mL in group B, which was significantly lower than (7.72 +/- 0.64) ng/mL in group A (P<0.05). The level of NSE was (8.02 +/- 0.72) ng/mL in the group C, which had no statistical significance with group A (P>0.05). The levels of TNF-alpha, IL-6 in cerebral tissue in group B were significantly lower than that of group A and C (all P>0.05).

CONCLUSIONEA at "Zusanli" (ST 36) has certain protective effect on septic rat's brain, which has some relationship with decreasing levels of cerebral tissue proinflammatory cytokine and plasma NSE. EA at non-acupoint has no the same action.

Objective To investigate the effect of ischemia and ischemia/reperfusion(I/R)in rat heart on matrix metalloproteinase-1(MMP-1).Methods The I/R animal models were established by shutting down and reopening the anterior interventricular branch with a silver clamp,then the distribution and amount of MMP-1 of the normal and I/R rat hearts were observed by immunohistochemical staining and Western blotting and analyzed by computer image analysis.Results 1.Immunohistochemical staining showed MMP-1 existed mainly in the cardiac matrix.There were strong positive reactions in fibrocytes,smooth muscle cells of the blood vessel and endotheliaI cells of capillaries.MMP-1 didn't show distinct changes 30 minutes after ischemia,while its concentration increased dramatically 60 minutes after ischemia.The positive reaction of MMP-1 increased 30 minutes after I/R,and 60 minutes after I/R there was large fusion areas in MMP-1 existing reglons.2.Quantitative analysis showed no dramatic changes of MMP-1 after ischemia for 30 minutes(P＞0.05),while dramatic changes were seen 60 minutes after ischemia(P＜0.05).MMP-1 changed dramatically 30 minutes and 60 minutes after I/R.3.Western blotting showed that there were no distinct naked-eye-observable changes.The bands of MMP-1 became widened 30 minutes after I/R,and became obviously widened 60 minutes after I/R.Conclusion 1.MMP-1 is secreted by fibrocytes,smooth muscle cells and endothelial cells of cardiac tissue under physiological conditions,and cardiomyocytes has the potential to secrete MMP-1 under ischemia or I/R.2.The longer time the heart ischemia lasts,the greater MMP-1 concentration will increase.Reperfusion can increase MMP-1 concentration to an even higher level,which may be the main cause of the collagen destruction after heart I/R.

Objective To study the effects ofautologous bone marrow mononuclear cells (BMMCs)transplantation during coronary artery bypass gafting (CABG) on myocardial infarct size. Methods Forty myocardial infarction patients diagnosed by coronary angiography (CAG) and SPECT and confirmed at surgery were enrolled and randomly assigned CABG alone (group Ⅰ) or CABG with intramyocardial or intracoronary injection of autologous BMMCs (group Ⅱ), 20 cases in each group. Baseline and followed up evaluations included SPECT and NYHA-FC before and after 6 months operation, recorded the major adverse cardiac events (MACE) at the same time. The number of autologous BMMCs injected was (6.84 ± 2.88) ×107 in group Ⅱ. Results There was no procedure-related complication during 6 months followed up in all patients. After 6 months operation,left ventricular ejection fraction in group Ⅱ was significantly higher than that in group Ⅰ [(57.40 ±5.21)% vs. (50.75 ±5.88)%,t =3.79,P＜0.05],NYHA-FC in group Ⅱ was significantly improved than that in group Ⅰ [(1.30 ± 0.47) grades vs. (1.85 ± 0.59) grades, t = 3.27, P ＜0.05],SPECT showed myocardial infarct size in group Ⅱ was significantly lower than that in group Ⅰ[(14.57 ±5.20)% vs. (20.45 ±5.18)% ,P ＜0.05]. Conclusion Autologous BMMCs transplantation during CABG is safe and feasible, which can reduce the myocardial infarct size in patients with myocardial infarction.
