Objective:To observe the effect of acupuncture on blood oxygen concentration in the brain of rats with post-traumatic stress disorder (PTSD) based on functional near-infrared spectroscopy (fNIRS),thus to reveal the mechanisms of acupuncture in intervening the brain function of PTSD rats.Methods:Sixty Sprague-Dawley (SD) rats were randomly divided into a blank group,a model group,a grasping group,a paroxetine group and an acupuncture group,with 12 rats in each group.Except the blank group,rats in the other groups all received incarceration plus electric shock for 7 d to prepare the PTSD animal model.One hour before the stress model was established,rats in each group received the designated intervention:rats in the blank group and the model group did not receive any intervention;rats in the grasping group received grasping and fixation;rats in the paroxetine group received paroxetine hydrochloride solution by intragastric administration;and rats in the acupuncture group received acupuncture.Six-day treatment was a course,with 2 courses of treatment conducted for a total of 12 d.After the modeling,rats in each treatment group received intervention for 5 d,and the fNIRS system was used to collect and record the changes in the concentrations of oxygenated hemoglobin (HbO2),deoxygenated hemoglobin (d-Hb) and total hemoglobin (t-Hb) of the involved rat's brain regions,and also to assess the brain function.Results:Compared with the blank group,the concentration of HbO2 was significantly increased,the concentration of d-Hb was significantly decreased,and the concentration of t-Hb was significantly increased in the model group and the grasping group after the intervention,and the differences were statistically significant (all P＜0.01).Compared with the model group,the concentrations of HbO2,d-Hb and t-Hb in the grasping group did not change significantly (all P＞0.05).Compared with the grasping group,the concentration of HbO2 was significantly decreased,the concentration of d-Hb was significantly increased,and the concentration of t-Hb was significantly decreased in the paroxetine group and the acupuncture group,and the differences were statistically significant (all P＜0.05).There were no significant differences in the concentrations of HbO2,d-Hb and t-Hb between the paroxetine group and the acupuncture group (all P＞0.05).Conclusion:Acupuncture can regulate the blood oxygen concentration in the brain of PTSD model rats,which may be an important mechanism of acupuncture in intervening the brain function in PTSD rats.

Objective To transplant the umbilical cord mesenchymal stem cells(UCMSCs) derived from human umbilical cord into cisterna magna of hypoxic-ischemic encephalopathy(HIE) rat model,and to observe their survival,proliferation and differentiation in the rat brain.Methods UCMSCs were isolated from human umbilical cord of babies delivered after full-term normal cesarean section,and labeled by bromodeoxyuridine(BrdU).Pregnant rats were randomly divided into experimental group(n=6) and control group(n=1).HIE models were built by ligating both sides of the uterine arteries of full-pregnant rats(21 days) in experimental group rats for 15 minutes.The neonatal rats in experimental group were divided into stem cells group(n=24) and PBS group(n=19) at random.The labeled UCMSCs were injected into cisterna magna of the rats in stem cells group,while PBS was injected into the rats of PBS group.In 1,2,3 and 4 weeks after transplantation,the brain tissue section slides were immunohistochemically stained with antibodies against BrdU,Nestin,neuron specific enolase(NSE) and glial fibrillary acidic protein(GFAP),and thionin.Control group with normal delivery was tested as concurrent control.Results At 1 week after transplantation,BrdU,Nestin,NSE and GFAP positive cells were found in the hippocampal dentate gyrus of the rats in stem cells group rats.The number of BrdU-positive and Nestin-positive cells increased(Pa0.05).The NSE-positive and GFAP-positive cells gradually increased from 1-4 weeks post transplantation and comparisons between groups had statistical significance(Pa

Objective To assess the effectiveness of donepezil versus huperzine in the treatment of elderly patients with mild cognitive impairment (MCI).Methods Total 122 elderly patients with MCI were divided into two groups:donepezil treatment (5.0 mg once daily) (n=71) and huperzine treatment group (0.1 mg twice daily) (n=51).All the patients were followed up for 24 weeks.Before and 12 weeks,24 weeks after drug treatment,the cognitive functions were evaluated,including MMSE,MOCA,ADAS-cog,CDR,GDS,ADL,HIS and HAMD.Results There was no significant difference in age,sex,education time and neuropsychology rating scales between the groups before drug use.As compared with the score before drug use,the donepezil group showed a significant increase in MMSE after 12-weeks (t=4.47) or 24-weeks (t=6.16) (P＜0.01),a decrease in the score of ADAS-cog after 12-weeks (t=2.33,P＜0.05) or 24-weeks( t=3.68,P＜0.05),and an increase in the score of MOCA after 24-weeks drug use (t=2.56,P＜0.05).The huperzine group showed significant improvement in MMSE after 24-weeks drug use (t=2.80,P＜0.05),but there was no difference in other time points or in the score of MOCA and ADAS-cog as compared with the score before drug use.After 24 weeks' treatment,the donepezil group had higher MMSE (t=2.01,P＜0.05) and lower ADAS-cog (t=2.09,P＜0.05) scores than the huperzine group.30 patients (total effective rate was 42.3 ％) and 9 patients (total effective rate was 17.6 ％ ) became improved in donepezil and huperzine group,respectively,with significant difference (x2 =8.26,P＜0.01 ).There were 5 cases in the donepezil group and 3 cases in the huperzine group getting slight side-effects which disappeared by continuing to take drugs or by adjusting drug taking time.Conclusions Donepezil and huperzine as the cholinesterase inhibitors are effective and safe,and the efficacy of donepezil is faster and better in treating elderly patients with MCI.

Objective To investigate the relationship between glucose excursion and cognitive function in aged type 2 diabetes. Methods A total of 248 aged type 2 diabetes were recruited in this study,all of them wore continuous glucose monitoring system (CGMS) for 3 d to evaluate the glucose excursion including mean amplitude of glycemic excursions (MAGE) which was used for assessing intra-day glycemia variability,and mean daily difference (MODD) which represented day-to-day glycemic variability.During the period of CGMS monitoring,all subjects accepted mini mental status examination (MMSE) for evaluating cognitive function.The relationships of MAGE and MODD with performance on cognitive tests were assessed. Results The over intra-day glucose excursion group had lower MMSE score than the narrow intra-day glucose excursion group[(24.25±6.75)vs.(25.97±0.47),P=0.025].The MMSE score was decreased in over day-to-day glucose excursion group compared with the narrow day-to-day glucose excursion group [(24.21 ± 6.47) vs. (26.01 ± 5.49),P =0.019]. A statistically significant association was observed between MAGE and the score of MMSE(r=- 0.308,P＜0.001),and between MODD and MMSE(r=-0.226,P =0.001).Conclusions Glucose excursion may affect cognitive function in aged type 2 diabetes.The over glucose excursion decreases the score of MMSE.
