To investigate the role of distribution and phylogeny of phenylethanoid glycoside in medicinal plants of Gesneriaceae, five phenylpropanoid glycosides, acteoside, paraboside B, isonuomioside A, paraboside II, and paraboside III were quantitatively determined in 12 species of Gesneriaceae by HPLC. The existence and content of these compounds were analyzed. The results showed that phenylethanoid glycosides were found in the most of those plants, but the kind of phenylethanoid glycosides varied in different species. Acteoside distribute in most of this plant group, paraboside B, isonuomioside A, paraboside II, and paraboside III were rare in those plants. The results of this study support morphological viewpoint that Trib. Trichosporeae is more developmental than Trib. Didymocarpeae.

Objective To assess the efficacy of alginate dressing in fat liquefaction of abdominal incision. Methods 76 patients with fat liquefaction of abdominal incision in our hospital were divided into the experimental group (42 patients) and the control group(34 cases). Both groups were given preventive antibiotics. The penetration, times of dressing change, interval of dressing change, healing cost, wound infection, period Ⅱ wound healing, time for the medicine to start working, time of healing were observed in the two groups. All results underwent t test and χ2 test. Results No distinct difference of healing cost between the two groups was observed. The experimental group treated with alginate dressing was better than the control group in other clinical indexes after treatment. Conclusions Application of alginate dressing is beneficial to management of fat liquefaction of abdominal incision and reduce time of healing and hospital stay.

Objective To observe the effects of electro-acupuncture ( EA ) on learning, memory and the morphology of hippocampal neural tissues in rats with a model of chronic cerebral ischemia.Methods One hundred and twenty male Sprague-Dawley rats were used. Chronic cerebral ischemia models were successfully established in 104 of them, and those rats were randomly divided into an EA group and a model group with 52 rats each. These were further subdivided into 1,2, 4 and 6 week subgroups with 13 rats in each. The EA group was given EA. The changes in spatial learning and memory ability were observed using a Morris water maze. The morphological changes in hippocampal nerve tissue were observed by HE staining.Results The escape latency in the EA group was significantly different from the model group at the 2nd, 4th and 6th week. The nerve cells in the dentate gyrus were more tightly and consistently lined-up and had rich layers, and the structures in the EA group were better than in the model group.Conclusions EA can improve spatial learning and memory and promote the repair of injury after cerebral ischemia.

Objective To investigate the effects of in vivo electroporation on plasmid mediated reporter gene expression and immunogenicity of DNA vaccine. Methods Luciferase expression plasmid was administered intramuscularly to BALB/c mice at 8μg and 40μg dosage level through injection with or without eletroporation Luciferase expression level in murine muscle was detected by IVIS imaging system 24 h after injection. DNA vaccine plasmid p1.0-gp1455m carrying codon-optimized env gene of CN54 strain ( HIV-1 CRF07_BC) was administered to mice at dosages of 8μg and 40μg through the two approaches mentioned above. Mice were immunized at week 0,2 and 4. Env-specific immune responses were detected at two weeks post the second and the third vaccinations. Env-specific antibody immune responses were determined by ELISA. Euv-specific cellular immune responses were determined by IFN-γ ELISPOT. Results Luciferase expression level in murine muscle was significantly increased as much as 35 folds through in vivo eletroporation. Results of ELISA and ELISPOT revealed that in vivo eletroporation could significantly enhance both the humoral and cellular immune responses induced by DNA vaccination. The responses induced by electrodelivered p1.0-gp1455m at 8 μg dosage were better than those induced by simple intramuscular injection with 40 μg of plasmid DNA. On the other hand, 2 injections followed by electroporation elicited comparable level of humoral and cellular immune responses with those induced by 3 injections without electroporation. Conclusion In vivo electroporation was capable of enhancing both the plasmid-mediated gene expression and immunogenicity of DNA vaccine.
