ObjectiveTo investigate the clinical efficacy of autohemotherapy plus pricking-cupping bloodletting in treating common acne.MethodFifty-six patients with common acne were randomly allocated to a treatment group of 28 cases and a control group of 28 cases. The treatment group received autohemotherapy plus pricking-cupping bloodletting and the control group, oral administration of licorzinc plus external application of benzoyl peroxide gel. In the two groups, the skin injury scorewas recorded and the overall therapeutic effects were evaluated.ResultThere was a statistically significant pre-/post-treatment difference in the skin injury score in the two groups (P<0.05). The skin injury score decreased more in the treatment group than in the control group (P<0.05). There was a statistically significant difference in the overall therapeutic effect between the two groups (P<0.01). The therapeutic effect was significantly better in the treatment group than in the control group.Conclusion Autohemotherapy plus pricking-cupping bloodletting is an effective, reliable, safe and convenient way to treat common acne.
3.Biocompatibility-associated index alterations in vascular implantation
Chinese Journal of Tissue Engineering Research 2007;0(52):-
Injury of blood vessel and subsequent repairing reactions to injury during vascular implant implantation can induce local and systematical inflammatory reactions,platelet and inflammatory cell aggregation,release of inflammation transmitter,chemotactic factor and tumor necrosis factor,which promotes vascular smooth muscle cell migration and proliferation,ultimately restenosis.Inflammatory reactions following implantation is highly correlated with intravascular restenosis.Well understanding of inflammatory factor features,monitoring of inflammatory factor index alterations,and taking some measures to increase histocompatibility can reduce inflammatory reaction intensity and duration.In addition,drug-eluting stent and skilled implanting technique can reduce incidence of inflammatory reactions.

Chinese Journal of Interventional Cardiology 1996;0(01):-
Objective To investigate the relationship between plasma lysophosphatidic acid(LPA) concentration and progression of aortic atherosclerotic lesions for hyperlipidemic diet fed infantile rabbits.Methods Two-month-old infantile rabbits(0.9-1.1 kg) were randomly assigned to normal diet group(group A,n=6) and hyperlipidemic diet group(group B,n=11).Blood lipid levels,LPA,nitric oxide(NO),malondialdehyde(MDA) and superoxide dismutase(SOD) concentrations were taken regularly.The thoracic aorta was taken from a hypertipidemic diet rabbit for pathological study at certion interval of time.Results Electronic microscope analysis revealed subtle changes of aortic wall during 1-2 weeks of the experiment.Fatty streaks(FS) appeared after 4 weeks of hyperlipidemic diet.The degree of FS increased gradually thereafter.Blood lipid levels increased significantly after 1 week of hyperlipidemic diet.Plasma LPA concentration reached its peak level before the appearance of FS.The NO,MDA and SOD concentrations of group B changed significantly proportional to the development of FS.Conclusion Measuring plasma LPA concentration,combined with serum NO,MDA and SOD concentrations can accurately reflect the formation and progression of FS.
