ABSTRACT

Objective To investigate the clinical effects and indications of the vacuum sealing drainage (VSD) in the treatment of severe diabetic foot gangrene.Methods We randomly recruited 60 cases,who had suffered from diabetic foot gangrene(DFG) at the grade of 3 -5,according to Wagner scale into VSD treatment groups and treated them with VSD methods.At the same time,62 DFG cases who had given routine drainage treatment one year ago were retrospectively analyzed as control group.The observed items included the wound healing time,number of dressing,outcome of treatment ( healing rate),the average days in hospital,total expenses of hospitalization and so on.Results The wound healing time of VSD treatment group and routine treatment group were ( 30.5 ± 6.8 ) days and ( 53.8 ± 5.5 ) days,respectively ( t =2.636,P < 0.01 ).The numbers of dressing were( 15.0 ± 4.7) days and ( 29.5 ± 6.1 ) days,respectively ( t =2.374,P < 0.01 ).The healing rates were 96.7% (58/60) and 87.1% (54/62),respectively(P <0.01 ).The average period in hospitalization were (20.1 ± 3.5 ) days and ( 36.5 ± 4.6 ) days,respectively ( t =2.564,P < 0.01 ).Total expenses of hospitalization were(20 155.6 ± 153.8) yuan RMB and(41 465.5 ± 146.6) yuan RMB,respectively(t =2.873,P <0.01 ).All the differences were statistically significant.Conclusion The VSD method is effective for the treatment of severe diabetic foot gangrene(DFG).It is able to reduce the time of wound healing significantly,increase the healing rate,shorten the hospitalization period and cut the general expenses during hospitalization.It' s an effective method for the treatment of DFG.

ABSTRACT

Object To study the chemical constituents of Dracaena cochinchinensis (Lour.) S. C. Chen. Methods The constituents were isolated on silica gel chromatography, preparative TLC, and spectral data. Results Six compounds were isolated and identified from the resin of D. cochinchinensis as: 1, 2, 4, 5-tetrachloro-3, 6-dimethoxybenzene (Ⅰ), cholest-4?-methyl-7-en-3?-ol (Ⅱ), cholest-4?-methyl-7-en-3-one (Ⅲ), hexacosane (Ⅳ), cholest-7-en-3?-ol (Ⅴ), cholest-7-en-3-one (Ⅵ). Conclusion Compounds Ⅳ-Ⅵ were isolated from D. cochinchinensis for the first time.
