[Effects of pre-electroacupuncture on blood pressure and cardiac function in high-salt-induced hypertension rats].

OBJECTIVE: To observe the effects of pre-electroacupuncture at "Taichong"(LR3), "Neiguan"(PC6) and "Waiguan"(TE5) on blood pressure and cardiac function of high-salt-induced hypertension rats, so as to explore the possible mechanism of pre-electroacupuncture in improving hypertension. METHODS: Twenty-four SD rats were randomly divided into control group, high-salt group and pre-electroacupuncture group, with 8 rats in each group. The hypertension model was established by feeding high-salt diet for 7 weeks. In the pre-electroacupuncture group, rats received electroacupuncture intervention at bilate-ral LR3, PC6 and TE5 (2 Hz/15 Hz, 2 mA) for 30 min, once a day, from the first day of modeling, for a total of 7 weeks. The blood pressure of rats was monitored by caudal artery noninvasive blood pressure measurement technique before and at the 1st, 3rd, 5th and 7th week of modeling. At the 8th week of the experiment, left ventricular catheterization was performed and biological signal acquisition system was used to detect left ventricular hemodynamics indexes and analyze left ventricular function, the car-diac mass ratio was measured to evaluate the degree of myocardial hypertrophy. The mRNA expressions of atrial natriuretic peptide(ANP), myosin heavy chain 7(MYH7), α-smooth muscle actin(α-SMA), interleukin(IL)-1ß, and IL-6 of myocardial tissues were detected by quantitative real-time PCR. Sirius red staining was used to observe the degree of myocardial fibrosis. RESULTS: Compared with the control group, systolic blood pressure, diastolic blood pressure, mean arterial pressure, left ventricular end-diastolic pressure (LVEDP), cardiac mass ratio，and the mRNA expressions of ANP, MYH7, α-SMA, IL-1ß, and IL-6, and sirius red staining area of myocardium were all significantly increased(P<0.01,P<0.05)，maximal rate of rise and descent of left ventricular pressure(LVP±dP/dtmax) were decreased (P<0.05,P<0.01) in the high-salt group. Compared with the high-salt group, rats in the pre-electroacupuncture group had lower systolic blood pressure, diastolic blood pressure, mean arterial pressure, LVEDP，cardiac mass ratio，higher LVP±dP/dtmax,down-regulated mRNA expressions of ANP, MYH7, α-SMA, IL-1ß, IL-6, and smaller area of sirius red staining(P<0.05, P<0.01). CONCLUSION: Pre-electroacupuncture tends to lower blood pressure, improve cardiac function and reduce myocardial fibrosis in high-salt-induced hypertension rats, which may be associated with inhibiting inflammatory response.

Correlation between recovery of motor function and regional glucose metabolism induced by CIMT in rats with cerebral ischemia / 复旦学报（医学版）

Objective To study the correlation between regional cerebral glucose metabolism and behavioral scores in middle cerebral artery occlusion(MCAO)model rats before and after the intervention of constraint induced movement therapy(CIMT),and the correlation between the natural recovery processand motor function recovery in MCAO model rats and the brain activation after CIMT intervention,and to further explore the mechanism of CIMT. Methods Twenty-two adult male Sprague-Dawley(SD)rats were randomly divided into an ischemic group treated with CIMT (CIMT,n=6),an ischemic group (Control,n=6),a sham-operated group(Sham,n=6),and a blank control group(Normal,n=4). The MCAO models of rats in the CIMT group and Control group were established by thread embolism method. The middle cerebral artery was not blocked during the operation for the Sham group,and the Normal group was not given any special treatment. After operation,rats in the CIMT group and Sham group were treated with CIMT. On the 7th day(d7)and the 22nd day(d22)after surgery,foot-fault test(FFT)and the beam balance and walking (BBW) test were used to evaluate the forelimb motor;micro positron emission tomography-computed tomography (micro PET/CT) imaging with fluorodeoxyglucose (18F-FDG) was used to scan the glucose metabolism in different brain regions of rats;Pearson correlation analysis was used to analyze the correlation between behavioral scores and glucose metabolism level in the CIMT group and Control group. Results On d7,the BBW score in the CIMT group and Control group was negatively correlated with glucose metabolism in the left insular cortex and the auditory cortex,and positively correlated with glucose metabolism in the right posterior hippocampus,superior colliculus,and inferior colliculus,with statistically significant differences;the FFT score was negatively correlated with glucose metabolism in the left somatosensory cortex, insular cortex and orbitofrontal cortex, and positively correlated with glucose metabolism in the right midbrain,with statistically significant differences. On d22, the BBW score in the CIMT group and Control group was positively correlated with glucose metabolism in the amygdala,caudate putamen,insular cortex and entorhinal cortex,and negatively correlated with glucose metabolism in the nucleus accumbens (Acb) core shell and caudate putamen in the right brain region,with statistically significant differences;the FFT score was negatively correlated with the entorhinal cortex in the right hemisphere and the difference was statistically significant. Conclusion The recovery of motor function promoted by CIMT was associated with the activation of both cerebral hemispheres in rats. The improvement of balance function promoted by CIMT in rats with cerebral ischemia was mainly related to the activation of Acb core shell in the right hemisphere. The recovery of fine grasping function promoted by CIMT may be related to the activation of the right entorhinal cortex.

[Effects of shuang shen tong guan decoction on the blood flow dynamics in rat model with myocardial infarction].

OBJECTIVE: To research the effects of Shuang Shen Tong Guan Decoction (SSTGD) on hemodynamics in rats with acute myocardial infarction (AMI). METHODS: SD rats were divided into sham operation group,model group, SSTGD low-dose group (2.5 g/kg), SSTGD middle-dose group (5 g/kg) and SSTGD high-dose group (7.5 g/kg). The levels of HR, MAP, LVSP, LVEDP, LVdp/ dt(max) and LVdp/dt(min) were detected by PowerLab at 0, 15, 30, 60, 90, 120, 180 min after administration. RESULTS: Compared with the sham operated group, the levels of HR, MAP were increased, the levels of LVSP, LVEDP, LVdp/dt(max) and LVdp/dt(min) were reduced at each detected point in model group, the difference was significant (P < 0.05). Compared with the model group, HR and MAP were decreased in SSTGD low-dose group, SSTGD middle-dose group and SSTGD high-dose group after 15 min; LVSP, LVEDP, LVdp/dt(max) and LVdp/dt(min) were higher, there was significantly difference (P < 0.05). Compared with SSTGD low-dose group and SSTGD middle-dose group, the difference of LVSP, LVEDP, LVdp/dt(max) and LVdp/dt(min) was statistically significant in SSTGD high-dose group (P < 0.05). CONCLUSION: SSTGD can improve cardiac function by increasing heart stroke volume, decreasing cardiac oxygen consumption and total peripheral vascular resistance.

CYP3A4 genetic polymorphisms predict cyclosporine-related clinical events in Chinese renal transplant recipients / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Cyclosporin A (CsA) is a substrate of both cytochrome P450 3A (CYP3A) and P-glycoprotein (P-gp), some of the single nucleotide polymorphisms (SNPs) in these genes are associated with interindividual variations in CsA pharmacokinetics. We studied the influence of these SNPs on the incidence of rejection and CsA nephrotoxicity, as well as pneumonia within one year after renal transplant and post-transplantation diabetes mellitus (PTDM), in order to find whether genetic evaluation may help to identify patients at risk and to modulate CsA therapy to optimize graft and patient outcomes.</p><p><b>METHODS</b>A total of 208 renal transplant recipients receiving CsA were genotyped for ABCB1 (C1236T, G2677T/A, and C3435T), CYP3A4 1G, and CYP3A5 3 by direct sequencing method. Retrospective case control study was utilized to identify the association between CYP3A4 1G, CYP3A5 3, ABCB1 genetic polymorphisms and CsA-related outcomes.</p><p><b>RESULTS</b>The patients with a CYP3A4 1G/ 1G genotype were found to have a higher incidence of acute rejection compared with those with CYP3A4 1/1.</p><p><b>CONCLUSION</b>CYP3A4 1G/1G genotype predict increased risk of acute rejection, so genetic evaluation may partly help to identify patients at risk and to modulate CsA therapy to optimize graft and patient outcomes.</p>
