BACKGROUND: At present, there are many drugs and therapeutic methods for dementia at home and abroad. Both xingding and piracetam are the kind of improver for circulatory obstruction and protector for nerve cells and can slow down the functional decline of brain tissue and provide improvement for cognitive deficit.OBJECTIVE: To observe the improvement of allied application of xingding and piracetam on cognitive function in treatment of vascular dementia.DESIGNS: Case-controlled study based on patients.SETTING: Neurological Department in Affiliated Hospital of Henan University. PARTICIPANTS: Totally 91 cases of vascular dementia hospitalized in Neurological Department of First Affiliated Hospital of Henan University from October 2000 to March 2002, which were randomized into treatment group of 48 cases and the control of 43 cases.INTERVENTIONS: In treatment group, xingding injection of 20 mL and piracetam of 8 g were administrated and 50 g/L glucose injection 250 mL was added respectively for intravenous injection, once daily and 14 days made one session. In the control, piracetam of 8 g was prescribed with 50 g/L glucose injection 250 mL added for intravenous injection, once daily and 14 days made one session. There was no any difference in other medication treatment. One month later after treatment of two groups, he patients were re-examined with mini-mental state examination(MMSE) and Hasegawa dementia scale(HDS) was used to assess the cogitative improvement and neurological defect scale(NDF) was used to analysis the improvement of neurological functional symptoms.MAIN OUTCOME MEASURES: ① Scores of MMSE, HDS and NDF in two groups. ② Analysis on therapeutic effects.RESULTS: Totally 91 cases entered the analysis on the results. There was no significant difference in MMSE and HDS before treatment in two groups. In treatment group, after treatment, MMSE and HDS scores were (23.26±5.12) and(2.78±3.46) respectively, indicating significant difference(t=4.79, 15.44, P＜0.01) compared with the control(19.14 ±3.21)and(15.21±2.29) . NDF score was 13.68±7.83 after treatment and the significant difference was presented compared with the control(17.33 ±8.81) . The total effective rate(total remarkable rate + progression) was 92% in the treatment group and was 56% in the control. By the comparison between two groups, the difference was significant(χ2= 15.48, P＜0.01).CONCLUSION: After treatment, MMSE score in treatment group was higher than that in the control and HDS score was lower than that in the control, explaining that xingding allied piracetam significantly improves cogitative function in the treatment of vascular dementia.

Objective To investigate the role of glucocorticoid receptor (GR) in the induction of neuronal apoptosis in spinal dorsal horn in chronic morphine tolerant rats. Methods Twenty healthy male SD rats weighing 300-350 g in which intrathecal (IT) catheter was successfully implanted without complication were randomized into 4 groups ( n = 5 each): group Ⅰ control ( group C);group Ⅱ morphine ( group M );group Ⅲ morphine +RU38486 (GR antagonist) (group MR) and group Ⅳ morphine + dexamethasone (GR agonist) (group MD).Normal saline 10 μl, morphine 10 μg, morphine 10 μg + RU38486 2 μg and morphine 10μg + dexamethasone 4 μg were injected IT twice a day at 8:00 and 20:00 for6 consecutive days in group C, M, MR and MD respectively. Tail flick latency (TFL) to a thermal nociceptive stimulus was measured every day at 30 min after IT administration in the morning (8:00). Hyperalgesia was considered to be a sign of morphine tolerance. The animals were killed at 7 days after IT drug administration. The L3-5 segment of the spinal cord was isolated for determination of neuronal apoptosis in spinal dorsal horn by TUNEL staining. Apoptotic index was calculated ( the number of apoptotic neurons/the total number of neurons × 100% ). Results TFL was significantly prolonged at day 1 and 3 of IT morphine 10 μg twice a day and returned to baseline at day 5 and 7 indicating morphine tolerance. RU38486 inhibited while dexamethasone enhanced morphine tolerance. IT morphine significantly increased the number of apoptotic neurons in spinal dorsal horn. Morphine-induced neuronal apoptosis was decreased by IT RU38486 and increased by IT dexamethasone. Conclusion Glucocorticoid receptors may be involved in morphine tolerance by inducing neuronal apoptosis in spinal dorsal horn.

Objective To discuss the value of hysteroseope in the diagnosis and treatment of infertility.Methods Retrospectively 60 cases of hysteroscope examimtiom on infertility patients.Results Uterine lesions had been found in 70%(42/60)cases.The most common type was endometrial polyps followed by endometrisitis.Conclusion Hysteroscope isone of the most effective examinations for diseases of uterine cavity.It has great value in the infertility diagnosis.

Objective To explore whether depressive disorder is one of risk factors for coronary artery disease (CAD) in enrolled patients and observe the level of inflammation markers in coronary artery disease patients with depression. Methods In all patients, we recoded clinical information and data from Hamilton Depression Rating Scale for Depression( HRSD)and measured concentration of monocyte chemoattractant protein-1 (MCP-1), tumour necrosis factor α (TNFα) and hypersensitive C-reaction protein (hsCRP). Results Among 87 patients with coronary artery disease, depressive disorder was diagnosed in 26 patients, the prevalence of depressive disorder was 29. 9%. Among 101 patients without coronary artery disease, 12 patients were suffering from depressive disorder, the prevalence of depressive disorder was 11.90%. The prevalence of depressive disorder in coronary artery disease group was statistically higher than that in non-coronary heart disease group (29.8% vs.11.9%, P<0. 01). The incidence of coronary artery disease was associated with age, hypertension,diabetes mellitus, hypercholesterolemia and depression. Life events and stage of heart function occurred differently between CAD patients with and without depression (P<0. 05). There were no differences in the degree of coronary artery stenosis and the type of treatment (P>0. 05) between the two groups. There were higher concentration of MCP-1 in coronary artery disease patients with depression, but no remarkable difference in hsCRP and TNFa.Conclusions There is high prevalence of depressive disorder, which is one of risk factor for coronary artery disease. The depressive disorder may be associated with inflammation biomarker in patients with coronary artery disease.

Objective To investigate the role of extracellular signal-regulated kinase(ERK)signal pathway in the spinal cord in the development of chronic morphine tolerance.Methods Thirty healthy male SD rats weighing 300-350 g in which intrathecal(IT)catheters were successfully implanted without complication were randomly divided into 3 groups(n = 10 each): group Ⅰ control(group C);group Ⅱ morphine tolerance(group M)and group Ⅲ morphine tolerance + PD98059(ERK upstream kinase MEK inhibitor)(group P).Morphine tolerance was induced with IT morphine 10 μg twice a day for 7 consecutive days.In group P PD98059 10 μg was injected IT at 30 min before each morphine administration.Tail flick latency(TFL)(the time between the onset of heat stimulus and voluntary tail withdrawal)was measured once a day at 30 min after first IT morphine administration and at 1 day after last IT morphine.Maximum analgesic effect(MPE)was calculated.MPE =(TFL after IT morphine - baseline TFL)/(12 - baseline TFL)× 100%.The animals were sacrificed after last TFL measurement.The L3-5 segment of the spinal cord was isolated for determination of the expression of μ-receptor and phosphorylated ERK 1/2(p-ERK1/2)by Western blot analysis and fluoroimmunoassay.Results Morphine tolerance was induced in group M and M + P.MPE was higher in group P than in group M.The expression of μ-receptor in spinal dorsal horn was significantly lower while the p-ERK1/2 expression was higher in group M than in group C.IT PD98059 significantly up-regulated μ-receptor expression and down-regulated p-ERK expression in group P as compared with group M.Conclusion ERK signal pathway is involved in the development of chronic morphine tolerance in rats.

Objective: To establish an HPLC-MS/MS method for the determination of hypericin in rat plasma. Methods: The sample was analyzed by HPLC-MS/MS after the addition of internal standard and then protein precipitation using acetonitrile. The sepa-ration was carried out on an Ultimate C18 column (150 mm × 2. 1 mm,5. 0 μm). The mobile phase was composed of acetonitrile∶ 5 mmol·L-1 ammoniumacetate (containing 0. 1% formic acid) (90∶10) at a flow rate of 0. 5 ml·min-1 under 35℃. The detection was performed with multiple teactions monitoring ( MRM) using an electrospray ionization ( ESI) . The precursor/product ion transitions were monitored at m/z 503. 2→m/z 405. 1 for hypericin and m/z 355. 0→m/z 41. 9 for the internal standard pioglitazone ( anion mode). Results:The good linearity of hypericin was obtained within the range of 0. 1-13. 2 ng·ml-1. The correlation coefficient was more than 0. 99 and the lower limit of quantification was 0. 1 ng·ml-1. The extraction recovery was within the range of 84. 19%-98. 71%. The precision of intra-and inter-day was below 18. 47%. Conclusion: The method is fast, sensitive and accurate, which provides research basis for the clinical further study of hypericin.
