RESUMEN

Objective To observe the effect of Huangqi granules combined with external treatment on the clinical therapeutic effects of typeⅡand Ⅲ stress injuries. Methods A total of 240 patients with typeⅡ andⅢ pressure injuries admitted to the Hengshui People's Hospital from January 2017 to March 2019 were enrolled. According to difference in therapeutic methods, the patients were divided into astragalus mongholicus granule group and routine treatment of Western medicine group, with 120 cases in each group. In both groups, the patients were given routine nursing treatment such as air cushion bed, regular body turn-over, nutrition support, health education, etc;in routine Western medicine treatment group, according to the principle of aseptic dressing change, the wounds were treated and covered with foam dressing; while in the astragalus mongholicus granule group, the routine nursing care and sterile dressing as above mentioned were also applied, additionally 3 bags of oral astragalus mongholicus granules mixed with boiled water each time, twice a day (equivalent to 10 g for each bag of Chinese herbal slices), 7 days as one course of treatment; at the same time, the wound was sterilized, debrided and washed with normal saline, and after drying, the rubber Shengji ointment for promoting growth of tissue was evenly spread on the wound and covered with foam dressing. In the two groups, the changes of pressure ulcer healing evaluation scale (PUSH) scores before treatment and 7, 14, 21 and 28 days after treatment, as well as the differences in wound healing time and clinical efficacy between the two groups after treatment were observed, and the recurrence rate was followed up for 10 weeks. Results Compared with routine Western medicine group, the Ⅱand Ⅲ wound healing times were significantly reduced in the astragalus mongholicus granule group [the days of wound healing for Ⅱ stress injury (days): 7.81±1.40 vs. 16.52±1.89, the days of wound healing for Ⅲ stress injury (days): 14.60±1.50 vs. 20.23±1.27, both P < 0.05]. With the prolongation of therapeutic time, the PUSH scores of two groups decreased gradually, there was no significant difference in the PUSH scores between the two groups before treatment and 7 days after treatment (both P > 0.05); after 14 days of treatment, the PUSH score of astragalus mongholicus granule group was significantly lower than that of the routine western medicine group (7.82±1.93 vs. 9.96±1.89), and lasted until 28 days (4.16±0.47 vs. 5.29±0.57), the differences being statistically significant (both P < 0.05). The total effective rate of the astragalus mongholicus granule group was significantly higher than that of the routine western medicine treatment group [99.41% (171/172) vs. 74.51% (114/153), P < 0.05], and the recurrence rate of the mongholicus granule group was obviously lower than the routine Western medicine treatment [3.60% (5/139) vs. 17.74% (11/62), P < 0.05]. Conclusion Oral astragalus mongholicus granules combined with myocreatic ointment external therapy can effectively shorten the healing time of type Ⅱand Ⅲ stress injury, improve the cure rate and reduce the recurrence rate.

RESUMEN

AIM:To investigate the effects of 17-AAG on apoptosis and cell cycle of HCT-15 cells and to clar-ify the related mechanisms .METHODS: MTT method was employed to evaluate the inhibitory effects of 17-AAG with Aifferent time and different doses on the proliferation of HCT-15 cells.The cells were stained with Annexin V-FITC/propid-iumiodide and measured by flow cytometry .The expression of STAT3, cyclin D1, Cyt C, caspase 9 and caspase 3 at mR-NA and protein levels was determined by RT-PCR and Western blotting .RESULTS:Treatment with 17-AAG at concentra-tion of 1.25~20 mg/L for 24 h and 48 h significantly inhibited the activity of HCT-15 cells at both time-and concentra-tion-dependent manners .Treatment with 17-AAG at concentrations of 0.425, 0.85 and 1.7 mg/L for 48 h significantly in-duced apoptosis and cell cycle arrest of HCT-15 cells.The exposure of 17-AAG at concentrations of 0.425, 0.85 and 1.7 mg/L for 48 h to the HCT-15 cells significantly down-regulated the expression of STAT 3 and cyclin D1 at mRNA and pro-tein levels, but up-regulated Cyt C, caspase 9 and caspase 3 mRNA and protein in a concentration-dependent manner . CONCLUSION:17-AAG inhibits the cell activity , induces apoptosis and G 1 arrest by down-regulating the expression of cyclin D1, and promoting the mitochondria apoptosis through STAT 3 pathway.
