To observe the therapy effect of ac iclovir(ACV) in the treatment of herpes simplex virus encephalitis(HSE). Methods:25 patients with HSE were given ACV intravenous infusion above one hour according to 5 mgkg-1, 3 times daily, for 7 days. Results:The therapeutic effect of HSE treated with ACV was bett er in 25 cases than that of 13 case of HSE treated without ACV, the extent of go od efficacy in the treatment of HSE and prognosis were related to time of using ACV instead to the patient's age. Conclusion: patient who has been diagnosed with HSE should be treated with ACV as soon as possible.

Objective: A HPCE capillary zone eletrophoretic method for the determination of evodiamine in Fructus Evodia was established. Similarly, areliable HPCE-FPS (fingerprint spectrum) was applied to compare quality of Fructus Evodia to 14 samples of 3 species from different areas. Methods: The evodiamine was detected on 254nm and proteins was on 196nm、254nm by HPCE. The electrophoretic parameters were optimized by studying the efffect of the buffer composition. Results: Calibration graph was constructed in the range 1.944 ?g?mL -1～7.766 ?g?mL -1 for evodiamine (r=0.9974). The regression equation was y= 188.7x-32.1. The average recovery was 101.3 (n=3). In this paper, the proteins of Frutus Evodia HPCE-FPS was established at 196nm and 254nm. Conclusion: Content of evodiamine from Fructus Evodia was determined by HPCE-CZE and HPCE-FPS and distinguished three species from different growing areas related to intrinsic quality of them. The research provides new technique for evaluating quality of traditional Chinese medicine.

Objective There are different degrees of angiogenesis in the tissues and organs of the patient with diabetic chron -ic vascular disease , and it is somehow difficult to observe angiogenesis .This study was to construct an experimental model of angiogen-esis in the diabetic rat in vivo. Methods Twelve SD rats were equally randomized into a normal control and a diabetes mellitus ( DM) group, the DM model constructed by intraperitoneal injection of streptozotocin .At 8 weeks after modeling , matrigel was planted under the abdominal skin of the control and model rats and removed 2 weeks later .Then the structure of the new vessels was observed by HE staining and the expressions of aminopeptidase P (JG12) and alpha-smooth muscle actin (α-SMA) detected by immunohisto-chemistry and immunofluorescence . Results Compared with the control rats , the DM models showed significant increases in the blood glucose level ([6.15 ±3.02] vs [35.08 ±6.92] mmol/L), 24-hour urine volume ([5.33 ±1.53] vs [105.00 ±20.82] mL), and 24-hour urinary protein level ([7.78 ±2.12] vs [47.70 ±9.63] mg/24 h) (P<0.01).The matrigel plug was white and transparent in the controls but red with a visible tiny vessel-like structures in the model rats .The vessel-like structures were found oc-casionally in the matrigel plug of the control animals but in large numbers with many erythrocytes in that of the DM models .In compari-son with the normal controls , the model rats exhibited significantly upregulated expressions of JG12 (7.76 ±1.85 vs 27.36 ±3.75, P<0.01) and α-SMA (10.22 ±2.64 vs 36.85 ±4.28, P<0.01) in the matrigel plug , and a vessel-like reticular distribution was ob-served. Conclusion Hyperglycemia may induce angiogenesis in the matrigel plug .The DM rat model of subcutaneous matrigel angio-genesis may contribute to the study of angiogenesis in diabetes .

Methods: The berberine hydrochloride and palmatine hydrochloride were determined using benzoic acid as an internal standard its detection wavelength was at 230nm. The optimized condition was achieved with a fused\|silica capillary 100?m?56.5cm, 10mmol?L -1 phosphate buffer(pH=4.80) containing 30% acetonitrile, a constant voltage of 20kv and temperature at 30℃. Results: Calibration curve was constructed in the range of 5?g?mL -1 ～100?g?mL -1 for berberine hydrochloride and palmatine hydrochloride, respectively. The regression equations were Y=0.02964X -0.00771 ( r =0.9998) and Y =0.01092 X -0.02939 ( r =0.9997) for berberine hydrochloride and palmatine hydrochloride, respectively. The average recovery was 98.7% and 102.1%( n =5), respectively. Conclusion: This method is sample, quick and sensitive.

Objective To investigate the roles of heavy metals in the onset of Alzheimer 's disease (AD) and vascular dementia (VaD) and to analyze the relationship between cognitive impairment and plasma heavy metal concentrations in patients with AD. Methods Fifty patients with AD, 20 with VaD, and 20 healthy controls were included in the study. According to the Clinical Dementia Rating (CDR), the AD patients were divided into mild dementia (CDR = 1 )and moderate to severe dementia (CDR = 2 to 3 ) groups. All the observational subjects performed the Mini-Mental State Examination (MMSE) score, Hachinski ischemic index score,and CDR score. A fasting venous blood sample was taken from all the subjects for detection of the heavy metal (Tu, Ca, Fe, Me, Zn, Hg, Cr, Co, Se, and Pb) concentrations at the same time.Results Compared to the control group, the plasma Cu concentration in the mild dementia and moderate to severe dementia groups increased significantly (0. 66 ± 0. 2 1, 0. 84 ± 1.11, and 0. 85 ± 1.12 ng/g, respectively (P ＜ 0. 05). There was no significant difference between the mild AD group and the moderate to severe dementia group. The Pb concentration in the control group was significantly lower than that in the moderate to severe dementia group (22.79 ±3.94 ng/gvs. 40. 82 ± 16.96 ng/g, P ＜ 0. 05 ). While there were no significant differences between the control and the mild dementia and moderate to severe dementia groups. The plasma Cu concentration (0.84 ± 1.25 ng/g vs. 0. 66 ± 0.21 ng/g, P ＜＜ 0. 05) and Pb concentration (32.42 ± 14. 12 ng/gvs. 22.79 ± 3.94 ng/g, P ＜ 0. 05) in the AD group were significantly higher than that in the control group. While there was no significant difference between the VaD group and the control group for metal concentrations. There was also no significant difference for metal concentrations hetween the VaD group and the AD group. Conclusions Some heavy metals, such as Cu and Pb might have participated in the pathogenic process of AD, but the heavy metal concentrations did not have close relationship with the onset of VaD. There was no significant correlation between the degree of cognitive impairment and the plasma metal concentrations in patients with AD.

Objective To prepare rabbit antibody against mouse AD-004 by AD-004 expressed in the prokaryotic expression system and to identify its distribution in the testis and adrenal. Methods The full-length cDNA of mouse AD-004 was cloned into PET28 plasmid, and the protein was induced in E. coli BL21 bacteria by adding IPTC and then purified by Ni2+ -NTA column. The purified protein was used as an immunogen to prepare polyclonal antibody ( pAb) of AD-004. The specificity of the antibody was detected by Western blotting. Immunohistochemical staining was performed in the mouse adrenal and testis via pAb of AD-004. Results Hisfused AD-004 was expressed efficiently in the prokaryotic system. Western blot analysis showed that the polyclonal antibody was duly bound to purified AD-004 with high specificity and sensitivity. AD-004 could be abundantly identified in the adrenal medulla and mainly expressed in the Leydig cells of testis. Conclusion The mouse protein of AD-004 is obtained from the prokaryotic expression system. The rabbit anti-AD-004 antibody has been prepared successfully. AD-004 protein is mainly localized in the interstitium of testis, suggesting that AD-004 may play a role in the synthesis of sex-steroid hormone.
