In addition to Routine Remedy for Angina Pectoris for all the patients. Refined Xue Fu Capsules and Xue Fu Capsules were prescribed for the first group (N = 30) and the second group (N = 34). The third group (N = 27) received only routine remedy as control in this single - blinded clinical trial. The total effective rate in these three groups were 96. 6%, 73. 5% and 70. 4%. The effect in the first group was significantly higher than the rest two groups (P

Objective:To investigate the retinal toxicity of chitosan and gentamicin- chitosan gel. Methods:Sixteen albino New Zealand rabbits (weighted 1. 5-2.5 kg) were used in this study. The rabbits were divided into 4 groups randomly;each group was injected with 0.1 ml PBS, gentamicin 2 mg/ml,3% Chitosan gel, and gentamicin-chitosan gel (2 mg/ml) respectively. ①Ophtahlmoscopic examinations were done. Retina was observed prior to injection , and on 1st, 3 rd, 7 th, 14 th d and 28 th d after injection with direct ophthalmolscope observations. ②Electroretinographs (ERGs) were recorded prior to injection, and then on 3 rd,7 th,14 th d and 28 th d after injection were carried out. ③Light microscope and transmission electronicmicroscope examinations were performed four weeks after the injection. All eyes were enucleated, the retina examples were observed under light microscope and transmission electronic microscope. Results:Intravitreous injection with 3% chitosan was free of retina toxicity. The retina toxicity effects of gentamicin 200 ?g could be found with transmission electron microscope, but gentamicin-chitosan gel with the same dosage could decrease the damage. Conclusion:The result shows that chitosan can be used in the intravitreous injection.

Objective To investigate the development and dynamic changes of host immune response in DBA/2 mice infected with Plasmodium yoelii 17XL. Methods Female DBA/2 mice were infected by intraperitoneal ( i. p. ) injection of 106 P. yoelii 17XL parasitized erythrocytes ( PRBC). Levels of IL-12, IFN-γ, IL-4, IL-10 and P. yoelii 17XL-specific antibody in sera were measured by ELISA. Concentrations of NO in cell supernatants were measured by the Griess reaction. Parasitemia,percentage of mononuclear-macrophages of individual mice were monitored daily, and phagocytosis of mononuclear macrophages was also observed. Results Primary parasitemia in vein blood was developed on day 3 postinfection, which peaked with a level of 46. 9% on day 9. Most mice cleared the infection and survived by day 20 postinfection. From day 6 to day 16, the phagocytosis of PRBC by rodent macrophages was observed on the blood smear. Infected mice had a continuously increased level of IL-12 in serum from day 1 postinfection. Accordingly, high level of IFN-γ was also detected in sera from day 1 postinfection,which peaked on day 6. Infected mice produced higher level of IL-4 and IL-10 in serum on day 6 postinfection, which peaked on day 9 and day 15 postinfection respectively. In addition, splenocytes from infected mice produced significantly higher level of NO on day 6 and 20 postinfection. Level of P. yoelii 17XL-specific IgG was determined in the sera of infected mice with a steadily increased trend after infection, which peaked on day 70 postinfection. Conclusions Effective polarizing of Thl cells is significant in inhibition of parasitemia and eventual clearance of the Plasmodium parasites. Activated mononuclear-macrophages play a key role in inhibiting parasitemia in the early phase of infection with P. yoelii 17XL.

Objective To investigate the tracking neurofibra pathway from the hippocamlpal neurons to septal nucleus,and to explore the effects and mechanisms of ghrelin on the learning and memory in septal nucleus lesion rats.Methods Retrogradely tracing method was used to observe Fluorogold (FG) reaching sites in hippocampus.The septal nucleus was destructed by direct current using stereotactic technique.Step-down test and morris water maze were used to test the effects of learning and memory ability by means of microinjecting ghrelin into hippocampal CA1 area in rats.Results After injection of FG into septal nucleus,retrogradely labeled neurons and neurofibra were found in the hippocampal neurons with FG.Ghrelin injection of hippocampal CAI area could promoter learning and memory ability in rats.It showed that the escaped latent period was significantly lengthened ( (3.2 ± 0.9) s vs (6.9 ± 1.1 ) s,P < 0.05) and the wrong numbers in 5 min were obviously decreased in escape response test; and the latency of looking for the plat was significantly shorter in morris water maze test ( 1.8 ±0.4vs 0.8 ± 0.1,P < 0.05 ).However the effects above-mentioned on learning and memory was significantly weak after septal nucleus lesioning.It showed that the escaped latent period was markedly shortened ( ( 19.5 ±3.2)s vs ( 10.5 ± 2.1 ) s,P < 0.05 ) and the wrong numbers in 5 min were obviously increased ( ( 3.9 ± 0.8 ) s vs ( 1.8 ±0.5 ) s,P<0.05 ) in escape response test.The latency of looking for the plat was significantly lengthened in morris water maze (P<0.05).Conclusion Ghrelin could elevate the learning and memory ability in hippocampus,and the effects may be related to the septal-hippecampus pathway.

Objective To study the DSA hepatoarteriography manifestations in hepatic carcinoma after endocare cryocare system (ECS)treatment for improving the comprehensive therapy of hepatic carcinoma.Methods Thirty eight male patients with primary liver cancer ( n =32) and hepatic metastasis (n=6) were enrolled in this study. Common hepatic arteriography or super-selection angiography was performed in all patients after ECS treatment in 7 days and 30-60 days.Results The foci covered with ice ball were shown as round or ovoid. Single tumor less than 5 cm was covered completely, while the shape of focus covered with more ice ball showed irregularity, mass-like and diffuse nodulss with diseminated tumor vessels and tumor stains. The shortcoming of ECS included 18 missed areas, hepatic A-V shunt and hepatic A-portal V shunt in 4, bleeding in puncture tract 5, and extravasation of contrast material in 6 cases. Delineated margin existed between the frozon area and surrounding tissues.Conclusions ①ECS is effective on liver tumor 5 cm. ③ Tendency of missed areas in huge tumor and widespread nodes accurs after ECS. ④Complication occurs easily during ECS performance near the hepatic capsule and porta hepatis. ⑤TACE would improve comprehensive therapy effect of liver cancer about7 days after cryotherapy.
