Conclusion: All the compounds except 14 are obtained from the stems of this plant for the first time.

Mixed saponin molecules in the extraction of Panax notoginseng(PNE) can be effectively desorpted into the molecular ionization for measurement and analysis by mass analyzer from matrix assisted laser desorption ionization-time of flight-mass spectrometry(MALDI-TOF MS). The saponin samples with chromatography purity were directly analyzed by MALDI-TOF MS, which indicated that the sensitivity of the method was higher than that of RP-HPLC. A technology of MALDI-TOF MS was directly employed to analyze the saponin kinds and their relative contents in Panax notoginseng(PN) while the saponins were perfectly extracted from the Chinese traditional medicine of PN. It was indicated that there were at least 20 saponins consisting of different molecular structure and that the content of both ginsenoside Rg1 and notoginsenoside R1 in PNE was relative high. R1 saponin was extracted and identified to follow its metabolism pathway by both thin layer chromatography and MALDI-TOF MS, respectively. The saponin fingerprinting maps in PNE can be established to evaluate the quality of PE and to study both metabolism pathway and mechanism of extra minim saponins in vivo.

Objective To observe the poet-operative clinical inpact on cervical intraepithelial neoplasia surgery by Loop elcctrosurgical excision procedure(LEEP),gelatin paste to improve the healing of the Cut,prevent the post-operative bleeding,and find out effective methods of preventing LEEP complications.Methods 100 patients with cervical intraepithelial neoplasia underwent LEEP in clinic.Divide them into two groups randomly,60 patients were adopted gelatin paste post-LEEP ag the cure group.while 40 patients were adopted as control group.Observation Vaginal bleeding,infection and cervical rear in short-term.Results In 60 patients of cure group,never patients with vaginal bleeding,infection and the cut healing in the short time.In 40 patients of control group,three patients with vaginal bleeding,two patients with infection,and three patients with bad healing.The different between two group with vaginal bleeding,infection and the cut healing time was significant(P＜0.05).Condusion gelatin paste can reduce bleeding.infection and cervical repair bad cmpllcations after cervical intraepithelial neoplasia surgery by LEEP.

OBJECTIVE:To study the protective effect of butylphthalide on the apoptosis of human umbilical vein endothelial cells (HUVECs) induced by Aβ1-42 and its mechanism. METHODS:HUVECs were divided into normal control group,Aβ1-42 group,TAK242 group(10 nmol/L),DMSO group(1‰DMSO)and butylphthalide low-concentration,medium-concentration and high-concentration groups (40,80,160 μg/L). Except for normal control group and DMSO group,other groups were given 50 μmol/L Aβ1-42 to culture HUVECs for 24 h. TAK242 group,DMSO group and butylphthalide low-concentration,medium-concentra-tion and high-concentration groups were given relevant concentration of drugs for 30 min,with 3 holes for each concentration. The cell viability was determined by CCK-8 assay;cell apoptosis was observed by Hochest 33342/PI double staining;the cell apoptotic rate was detected by AnnexinⅤ-fluorescein isothiocyanate (FITC) flow cytometry;the protein expression of TLR-4 and COX-2 were determined by Western blot assay;the contents of IL-1 and TNF-α were detected by ELISA. RESULTS:Compared with nor-mal control group,cell viability of HUVECs were decreased in Aβ1-42 group;while apoptotic rate,protein expression of TLR4 and COX-2,the contents of IL-1 and TNF-α were increased. Compared with Aβ1-42 group,cell viability of HUVECs were increased in TAK242 group and butylphthalide low-concentration,medium-concentration and high-concentration groups;while apoptotic rate, protein expression of TLR4 and COX-2,the contents of IL-1 and TNF-α were decreased,with statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Butylphthalide can reduce HUVECs apoptosis induced by Aβ1-42,which may be related with inhibiting the expression of TLR4,COX-2 and inflammatory factors.

Objective To observe the effects of electro-acupuncture on the expression and inhibition of DNA binding protein 2 (Id2) and myelin basic protein (MBP),and to explore the mechanism of remyelinization after compressive spinal cord injury (CSCI) in rats.Methods Fifty-four SD rats were randomly divided into a control group and a treatment group,and each was further subdivided into 3 time point subgroups:3,7 and 14 days.There were 9 rats in each subgroup.The CSCI models were made with a self-designed method.The acupuncture points Jiaji (EX-B2),bilateral Zusanli (ST36) and Taixi (KI3) were selected for treatment.Electro-acupuncture (continuous wave,2 Hz,1.5 V)was applied to the bilateral Zusanli (ST36) and Taixi (KI3) points.The control group received the injury but no treatment.The changes in the ultrastucture of the nerve fibers＇ white matter were de-termined by transmission electron microscopy (TEM).The alterations in the expression of MBP and Id2 were observed by double labeled immunofluorescence and Western blotting on the 3rd,7th and 14th day after the injury.Results TEM showed that the myelin sheaths in the control group had degenerated,swollen,and even broken down after CSCI.Changes to the myelin sheaths in the treatment group were milder than those in the control group.The immunofluorescence results showed the amount of Id2-immunoreactive oligodendrocytes in the control group to be (20 ±2) on the 3rd day after CSCI,becoming (16 ± 1) on the 14th day.The differences among the 3 control subgroups were not statistically significant.The amount of Id2-immunoreactive oligodendrocytes in the treatment group was (13 ± 1) on the 3rd day,reaching a minimum the 14th day.The differences among the 3 treatment groups were statistically significant.The differences compared with the control group at the same time points were also statistically significant.Western blotting showed that the expression of Id2 in the contrast and treatment groups was (1.12 ±0.12) and (0.67 ±0.01) respectively on the 3rd day after CSCI,and both decreased with time.The expression of Id2 in both groups reached their minima ((0.86 ±0.02) and (0.25 ±0.01) respectively) on the 14th day.The difference between the treatment groups and the contrast group was statistically significant at each time point.The expression of MBP in the contrast and treatment groups at day 3 was (0.44 ± 0.02) and (0.67 ± 0.04) respectively,and these increased with time.The expression of MBP in both groups peaked at the 14th day (at (0.95 ± 0.04) and (1.74 ± 0.09) respectively).These differences were again statistically significant.Conclusion Electro-acupuncture can regulate the expression of Id2 and MBP after CSCI.The down-regulation of Id2 which controls MBP negatively and the up-regulation of MBP may contribute to remyelination in the injured spinal cord.
