OBJECTIVETo verify the clinical efficacy of acupuncture combined with auricle cutting method for treatment of blood stasis-type psoriasis.
METHODSFifty-six cases of blood stasis-type psoriasis were randomly divided into a combined therapy group, a auricle cutting group, an acupuncture group and a control group, 14 cases in each one. Based on regular treatment of TCM decoction in four groups, the combined therapy group was treated with acupuncture and auricle cutting method, and the auricle cutting group was treated with sham-acupuncture and auricle cutting, and the acupuncture group was treated with acupuncture and sham auricle cutting, and the control group was treated with sham-acupuncture and sham auricle cutting. The acupuncture was applied at Dazhui (GV 14), Feishu (BL 13), Ganshu (BL 18) and Geshu (BL 17), etc., and manipulated with routine technique; in the sham acupuncture, the needle was inserted into dermis layer so that the needles could be swung without being dropped out. In the auricle cutting, erbeixin (P1) of unilateral auricle was selected and cut by Chan needle to perform bloodletting; in the sham auricle cutting, the neighborhood approximately 0.5 cm next to erbeixin (P) of auricle was selected as cutting area. The treatment was given once a day, seven days as a treatment session for totally two sessions. Psoriasis area and severity index (PASI) before and after treatment was observed and efficacy of each group was compared.
RESULTSThe effective rate was 57.1% (8/14) in the combined therapy group, which was superior to 14.3% (2/14) in the auricle cutting group, 7.1% (1/14) in the acupuncture group and 0.0% (0/14) in the control group (all P < 0.05). The scores of PASI were all decreased in each group after the treatment (all P < 0.05), which was the most significant in the combined therapy group (all P < 0.05). After factorial analysis, the main effect was P < 0.05 in the auricle cutting, P < 0.05 in the acupuncture and P < 0.05 in interaction effect of combined therapy.
CONCLUSIONThe scores of PASI of blood stasis-type psoriasis could be effectively reduced by acupuncture, auricle cutting method and TCM decoction, among which the interaction effect of auricle cutting and acupuncture combined with TCM decoction is the most significant.

Translocating protein and translocating peptides have therapeutic potential against tumors by exposing the cytotoxic domains of toxic proteins to the cell cytosol. The aim of this study is to investigate the effect of N-terminally fused PE translocating peptides on granzyme B (GrBa) activity. PE II-GrBa fusion protein genes were constructed by replacing N-terminal signal and acidic dipeptide sequence of human granzyme B gene with two truncated translocating sequences of Pseudomonas exotoxin A (PE II aa 280-364/358) by recombinant PCR, and then cloned into pIND inducible expression vector. The resulting pIND-PE II-GrBa expression vectors were co-transfected with assistant plasmid pVgRXR into HeLa cells through lipofectamine, followed by selection on G418 and zeocin. The resistant cells were collected and induced with ponasterone A. Western blot analysis demonstrated that ponasterone A induction caused the expression of PE II-GrBa fusion proteins, and indirect immunofluorescence detected giant sized multinucleated cells, suggesting cytoskeletal and mitotic abnormalities as reported in our previous studies. Western blot, enzymatic activity assay and cell counting analysis indicated that two types of PE II-GrBa fusion proteins were capable of cleaving both endogenous and exogenous substrates of granzyme B, and inhibiting the growth of cells. The PE II (aa 280-358)-GrBa was shown to have higher serine protease activity and stronger growth inhibitory effect. Such inhibition was presumably associated with G2 arrest as determined by cell cycle analysis. These data prove that PE II-GrBa fusion proteins have cell inhibitory effect similar to GrBa, and that the shorter PE-derived peptide exerts less influence on GrBa activity. This study helps to optimize the construction of recombinant protein comprising translocating peptides and cytotoxic molecules for tumor cell killing.

To find novel antihepatitis drugs, a series of nitrate-oleanolic acid (OA) hybrids (10a, 10b, 11a-11e and 12a-12c) were designed and synthesized on the basis of previous studies using OA as lead compound, which is widely found in natural plants and liver-specific metabolism. In the present study, ten novel NO-releasing derivatives of OA were synthesized by connecting nitrate to the OA-3-OH through varying lengths of linkers containing antioxidants which were designed to increase the ability of these target compounds to scavenge free radicals. The structures of these objective compounds were determined by IR, MS, 1H NMR and elemental analysis. Their protective effects on anti-Fas mediated HepG2 cell apoptosis were in vitro evaluated by LDH assay. Compound 12a is the most potent inhibitor. Its effect on anti-Fas mediated HepG2 cell apoptosis and amount of NO-releasing in vitro are similar to those of positive control NCX-1000.
