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.

To evaluate the different anesthesia in elderly patients with gastric cancer surgery influence blood con-centrations of melatonin and its correlation with postoperative agitation. The agitation scroes were evaluated and re-corded,and the blood samples were taken twice:before induction as well as just at the end of surgery,then making correlation analysis. The agitation scroes were significantly lower in group ET than in group T(P<0.01);the level of postoperative blood concentrations of melatonin was higher in group ET than that in group T(P<0.01);the agi-tation scroes and the level of postoperative blood concentrations of melatonin were negatively correlated ( r =-0.429,P<0.05).

A quantitative analysis method of multi-components with a single marker (QAMS) for simultaneous determination of six marker compounds (one from phenolic acids and five from phthalides) in Chuanxiong Rhizoma was established by applying HPLC and using butylidenephthalide as the internal reference substance. And also the feasibility and accuracy of the established method for quality evaluation and application of Chuanxiong Rhizoma were investigated and validated. The analysis was performed with the mobile phase consisting of acetonitrile - 0.2% aqueous formic acid. The flow rate was 1.0 mL . min-1 and the column temperature was maintained at 30 °C. The detection wavelengths were set at 252 nm (for ferulic acid, Z-ligustilide, and butylidenephthalide) and 266 nm (for senkyunolide I, senkyunolide A, and coniferyl ferulate), separately, and 20 µL was injected for analysis with gradient elution. The results showed that there were no significant differences observed between the HPLC-QAMS method and the external standard method (RSD <5%). The relative correction factors were credible (RSD < 5%) in changed chromatographic conditions. The established HPLC-QAMS method can be accurately used for simultaneously evaluating and controlling the quality of Chuanxiong Rhizoma with multi-components.

ObjectiveTo investigate correlative factors of non-operative treatment in the senile cataract, and provide gist for the health education measures.Methods1513 retiring old people had a whole medical examination, and the data was analyzed.ResultsThe proportion of binoculus cataract was 45.9%. Predilection age was 70～79 years old. Cognition information and iatrogenic effects were major risk factors in the non-operative therapeutic agents. Cataract was the third in the elder chronic disease.ConclusionMany senile patients with cataract have not enough knowledge about cataract operation although having better medical treatment and economy conditions. So the closed attention to the health education must be paid in the future.

Objective To investigate the relationship between the changes in intracranial excitatory amino acid(EAA) levels and the incidence of postoperative cognitive dysfunction (POCD) in eldedy patients after general anesthesia. Methods Forty ASA Ⅰ-Ⅲ patients of both sexes aged 65-79 yr weighing 48-76 kg undergoing elective non-cardiac surgery under general anesthesia were studied.Anesthesia was induced with midazolam,fentanyl,etomidate and succinylcholine and maintained with continuous iv infusion of propofol,remifentanil,isoflurane inhalation and intermittent iv boluses of vecuronium.The right internal jugular vein was cannulated with a catheter which was advanced cephalad until jugular bulb.The jugular bulb venous blood samples were taken before (T0,baseline),at the end of (T1) and at 24,48 and 72h(T2-4) after operation for measurement of plasma concentrations of glutamate (Glu),aspartate (Asp) and glycine (Gly) by RP-HPLC.The cognitive function was evaluated by mini-mental state examination (MMSE) at T0 and T4.Results Eleven of the 40 patients developed POCD (28%).The plasma Gh,Asp and Gly concentrations were significantly increased after operation as compared with the baseline values in POCD patients and were significantly higher than in non-POCD patients.The plasma concentrations of Glu and Asp were negatively correlated with MMSE score(Glu:r=-0.86.P<0.01;Asp:r=-0.99,P<0.01).Conclusion Elderly patients may develop POCD after operation performed under general anesthesia through increase in intracranial EAA levels.

Objective To observe the pathological changes of heart failure caused by transverse aortic constriction in rats.Methods Partial thoracotomy was performed to the second rib and the transverse aortic constriction was performed between the innominate and left carotid arteries to establish a model of heart failure in 24 rats.The same operation was performed on another 8 rats, except for the ligation of the transverse aorta.Echocardiographic assessment, hemodynamic measurement, myocardial histopathological examination and NT-proBNP measurement were performed to the sham group at 12 weeks and model group at 4 weeks, 8 weeks, 12 weeks after the operation.Result At 4 weeks after the operation, NT-proBNP, EF, FS and -dp/dtmax of the model group was significantly increased and LVESV, +dp/dtmax of the model group were significantly decreased (P<0.05).At 8 weeks after the operation, EF and-dp/dtmax of the model group were increased and +dp/dtmax of the model group was significantly decreased (P<0.05).At 12 weeks after the operation, NT-proBNP, EF and +dp/dtmax of the model group were decreased, and LVESV, LVEDV and -dp/dtmax of the model group were increased (P<0.05).The cardiomyocytes became hypertrophic and lined up in disorder at 4 weeks after the operation.Pathologic examination of the myocardial tissue showed connective tissue proliferation and inflammatory cell infiltration at 8 weeks after the operation, and cardiomyocyte apoptosis and collagen fiber deposition at 12 weeks after the operation.Conclusions Transverse aortic constriction induces heart failure in rats.The pathological processes are compensatory hypertrophy at 4 weeks after the operation, initial reaction of decompensation at 8 weeks after the operation, and heart failure at 12 weeks after the operation.

Objective To assess the correlation between inflammation,specific immune response and coronary heart disease(CHD). Methods Thirty healthy cases passed the health examination were taken as the control group. Eighty cases who were diagnosised into CHD,affirmed by coronary angiography,were divided into three groups: acute myocardial infarction (AMI) group(26 cases),unstable angina pectoris (UP) group (24 cases),and stable angina pectoris (SP) group(30 cases). All the cases were tested on the concentrations of C-reactive protein(CRP),IgA,IgG,IgM in serum. Results The serum indices of CRP,IgG,IgA in AMI group and UP group were significantly difference than those in the control group (P0.05). Conclusion The correlation between inflammation and immune system activation are closely associated with CHD.
