Objective To investigate the influence of deep brain stimulation (DBS) at high frequency to the bilateral nucleus accumbens on morphine-induced conditioned place preference (CPP) and relapse behaviors during extinction phase in rats. Methods Twenty adult SD rats were employed in the experiment. Through stereotactic operation, outer electrode cannula was implanted into rats' bilateral nucleus accumbens. After 5 days of rest, the morphine-dependent rat model with CPP was established through intraperitoneal morphine injection (10 mg/kg). The rats, after being randomly divided into experimental group (morphine+DBS) and control group (morphine+sham DBS), were electrically stimulated using DBS circuits. Rats in the experimental group were given high frequency electrical stimulations while the control group was given sham stimulation. The CPP score of the two groups was recorded the day after stimulation until successful extinction and then the extinction time was compared between the two groups. After successful extinction the rats were given small dose of morphine to trigger relapse within 24 hours, and the CPP score was recorded and compared between the two groups.Results Compared with the control group (six days), the experimental group (26 days) had a longer extinction time. After relapse, the retention time within the drug-paired chamber of the experimental group was (357.01±192.72) s, obviously shorter than that of the control group ((704.91±181.35) s;t=2.370, P=0.034 6). Conclusion High frequency DBS to rats' bilateral nucleus accumbens can prolong extinction time but inhibit relapse behavior.

PURPOSE: Diabetic nephropathy (DN) is a prevalent chronic microvascular complication of diabetes mellitus involving disturbances in electrolytes and the acid-base balance caused by a disorder of glucose metabolism. NHE1 is a Na+/H+ exchanger responsible for keeping intracellular pH (pHi) balance and cell growth. Our study aimed to investigate roles of NHE1 in high glucose (HG)-induced apoptosis in renal tubular epithelial cells. MATERIALS AND METHODS: Renal epithelial tubular cell line HK-2 was cultured in medium containing 5 mM or 30 mM glucose. Then, cell apoptosis, oxidative stress, NHE1 expression, and pHi were evaluated. NHE1 siRNA and inhibitor were used to evaluate its role in cell apoptosis. RESULTS: HG significantly increased cell apoptosis and the production of reactive oxygen species (ROS) and 8-OHdG (p<0.05). Meanwhile, we found that HG induced the expression of NHE1 and increased the pHi from 7.0 to 7.6 after 48 h of incubation. However, inhibiting NHE1 using its specific siRNA or antagonist DMA markedly reduced cell apoptosis stimulated by HG. In addition, suppressing cellular oxidative stress using antioxidants, such as glutathione and N-acetyl cysteine, significantly reduced the production of ROS, accompanied by a decrease in NHE1. We also found that activated cyclic GMP-Dependent Protein Kinase Type I (PKG) signaling promoted the production of ROS, which contributed to the regulation of NHE1 functions. CONCLUSION: Our study indicated that HG activates PKG signaling and elevates the production of ROS, which was responsible for the induction of NHE1 expression and dysfunction, as well as subsequent cell apoptosis, in renal tubular epithelial cells.
