AIM: According to the functions of Lumbago Suppositiory (Radix Aconiti, Ramulus Cinnamoni, Moschus, etc) (LS), we observed the connection among anti-inflammatory, analgesia and promoting blood circulation and removing blood stasis. METHODS: Rat chemical radiculoneuritis model was set up to observe influence of LS on inflammation, pain threshold, gait and PLA_2 in serum, content of adrencorticoids and adrenalin. Cold accumulation type of blood stasis symptom model was built up to observe the influence of LS on blood rheological property, effect of LS on mouse's micro-circulation in ears was also observed. RESULTS: Lumbago Suppository inhibited inflammation of rat radiculoneuritis model obviously and had recovery of functions for gait and pain threshold. And it also could reduce the content of PLA_2 in serum and raise the level of adrenocorticoids and adrenalin. It also obviously changed "blood stasis symptom”, rat blood rheological property and auricle micro-circulation of mouse. CONCLUSION: Lumbago Suppository's functions of anti-inflammatory and analgesia have strong relation ships with promoting blood circulation and removing blood stasis.

Background Retinal angiomatous proliferation (RAP) is a subtype of neovascular age-related macular degeneration (AMD).There are currently very few studies on RAP.Objective This study was to explore the pathogenic mechanism of RAP in apolipoprotein E-deficient (ApoE-/-) mice with dyslipidemia.Methods Twenty-four 2-month-old SPF ApoE-/-mice were randomly divided into the high fat diet group and the normal diet group,and twelve 2-month-old C57BL/6 mice received the normal diet as controls.A diet with a higher content of fat was given for 4 consecutive months in the high fat diet group,and normal diet was given in the same way in the mice of the normal diet group.The mice were sacrificed at 6 months of age.The expression of vascular endothelial growth factor (VEGF) in the retinal pigment epithelial (RPE) cells,the expression of vascular endothelial growth factor receptor-2 (VEGFR-2) in the outer plexiform layer (OPL),microvascular density (MVD) and microvascular area (MVA) in the OPL were examined by immunohistochemistry and semi-quantitatively by histopathology with the Mias 2000 Imaging Analyzer System.The expression of VEGF protein in the retina was examined by Western blot.Results The MVD in the retinal OPL were (20.67±3.20) and (19.50± 1.87),respectively,in the ApoE-/-mice of the high fat diet group and the normal diet group,which were significantly higher than that (12.50±1.87) of the C57BL/6 normal diet group (all at P＜0.01).MVA in the retinal OPL were (626.49± 120.99) μm2 and (514.06±88.83) μm2 in the ApoE-/-mice of the high fat diet group and the normal diet group,respectively,showing a significant increase in comparison with the (336.52±84.96) μm2 of the C57BL/6 normal diet group (P＜0.01).The staining area of VEGF in RPE cells was (21 048±1849) μm2 in the ApoE-/-mice of the high fat diet group,showing a significant increase in comparison with the (17 116±2023) μm2 of the C57BL/6 normal diet group.However,no significant difference was found in the staining area of VEGF between the ApoE-/-mice with normal diet group and the C57BL/6 normal diet group ([17 854±2967] μm2 vs.[17 116±2023] μm2) (P＞0.05).Significant elevation was also seen in the staining area of VEGFR-2 in the retinal OPL of the ApoE-/-mice of the high fat diet group (12 193±3806)μm2 and the ApoE-/-mice of the normal diet group (11 969± 3616)xm2 compared with C57BL/6 mice of the normal diet group (5387±2225)μm2(all at P＜0.01).The relative expression values (VEGF/β-actin) of VEGF in the retinas were (1.51 ±0.32) and (1.17±0.39) in the ApoE-/-mice of the high fat diet group and the normal diet group,respectively,showing a significant increase in comparison with (0.28±0.14) of the C57BL/6 normal diet group (P＜0.01).Conclusions The expression of VEGF and VEGFR-2 in the retinas increases in the ApoE-/-mouse,which leads to the enlargement of MVD and MVA in the retinal OPL and subsequent RAP occurrence.

The study is aimed to assess the genetic diversity and genetic relationship of 18 Sarcandra glabra resources from different populations,and guide parent selection of cross breeding between these resources. The molecular marker technique ISSR was used to investigate the genetic diversity of the 18 resources. Data was analyzed by POPGEN 32, and a cluster diagram was presented by UPGMA. One hundred and ninety-eight amplified fragments were obtained using 23 ISSR primers. One hundred and eighty-four polymorphic loci were identified. Nei's genetic diversity index (h) was 0.32, Shannon diversity index (I) was 0.485 4. The genetic similarity coefficient among the resources ranged from 0.383 8 to 0.878 8 in an average of 0.661 2. The genetic distance between sample S2 and sample S18 was the farthest, so as between sample S3 and sample S18 both Nei's genetic distance was 0.957 5, The genetic distance between sample S4 and sample S5 was the closest, the Nei's genetic distance was 0.129 2,and the sample S1, S2, S3, S7, S10 were significantly different from the others based on the clustering analysis, the three groups S2 vs S3, S2 vs S6, S2 vs S18 were the best parent group selection. There was a middle level of genetic differentiation in the resources. The genetic distance between resources gives useful information to guide parent selection of cross breeding.
