Objective To investigate the effects of acupuncture at points Baihui (GV20), Yintang (Ex-HN3) and Sishencong (Ex-HN1) on spatial learning and memory abilities and hippocampal expression of brain-derived neurotrophic factor (BDNF) in a rat model of post-stroke depression (PSD). Method Thirty male adult SD rats were allocated, using a random number table, tocontrol, acupuncture and sham operation groups, 10 rats each. A rat model of PSD was made by classical middle cerebral artery occlusion (MCAO) using an intraluminal thread technique, chronic unpredictable mild stress (CUMS) and solitary feeding. At the fourteenth day after the beginning of stress, the acupuncture group received acupuncture intervention for 14 consecutive days. At one week after the end of stress, the Morris water maze test was conducted to assess rat spatial learning and memory abilities. After the completion of the water maze test, hippocampal CA3 regional BDNF expression was determined by immunohistochemical method. Result Rat learning and memory abilities decreased significantly in the control group compared with the sham operation group (P<0.05). Space exploration time and the number of crossing platform reflecting memory abilities decreased significantly in the control group (22.36±6.20 s and 3.72±0.90 times, respectively) compared with the sham operation group (48.73±5.40 s and 8.60±1.10 times, respectively); there were statistically significant differences (P<0.01). Learning abilities, space exploration time, the number of crossing platform and BDNF expression increased significantly in PSD rats treated with acupuncture compared with the control group; there were statistically significant differences (P<0.01). Conclusion Acupuncture can improve spatial learning and memory abilities and raise hippocampal regional BDNF levels in rats with post-stroke depression.

BACKGROUND: Hepatitis B virus (HBV) recurrence following liver transplantation has been difficultly treated, and antiviral therapy following HBV recurrence has been less reported yet.OBJECTIVE: To investigate the antiviral therapy using Adefovir + Lamivudine + anti-hepatis B immunoglobulin on liver functional improvement following liver transplantation.METHODS: A total of 208 cases with hepatitis B-related end-stage liver disease following liver transplantation were selected from Liver Transplantation Center of Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from January 2005 to October 2008. All patients were treated with Lamivudine + anti-hepatis B immunoglobulin so as to prevent from HBV recurrence. At 6-43 months after following up, HBV recurrence was found in 19 cases, including 13 with positive HBeAg and 8 with YMDD mutation. The 19 patients were treated with Adefovir based on the application of Lamivudine + anti-hepatis B immunoglobulin.RESULTS AND CONCLUSION: At 12, 24, and 48 weeks after treatment, DNA and glutamic-pyruvic transaminase of 19 cases were significantly decreased (P < 0.01). After 48-week treatment, recovery rate of glutamic-pyruvic transaminase, negativity rate of HBeAg, and negativity rate of HBV DNA were 84.1 %, 76.92%, and 78.9%, respectively. The results demonstrated that the application of Adefovir + Lamivudine + anti-hepatis B immunoglobulin effectively inhibited viral replication and prevented HBV recurrence following liver transplantation.
