ABSTRACT
At present, selective 5-hydroxytryptamine (5-HT) reuptake inhibitors (SSRIs) and 5-HT and noradrenaline (NA) re-uptake inhibitors ( SNaRI) are the first choice for the clinical treatment of depression, however, the clinical adverse effects of the drugs have become a prominent problem affecting the clinical efficacy. Chinese medicines have some experience in the treatment of depres-sion, and the combined use with the above antidepressants can enhance the efficacy and / or reduce the adverse effects. The article re-viewed the status of the combination of SSRIs and Chinese medicines in order to provide reference for the clinical treatment of depres-sion.
ABSTRACT
Combined application of Chinese and western medicine is widespread in clinical real world because national policy emphasizes both Chinese medicine and western medicine. The studies on the combined use of Chinese and western medicine, are conducive to clinical precise positioning, promote self positioning of Chinese patent medicines and Chinese medicine enterprises based on suitable application fields, and provide direction for the deepening development of herbal industry. In addition, the studies on clinical evaluation and mechanism of combined use of Chinese and western medicine can provide basis for formulating national health policies and promoting medical resource fairness.
ABSTRACT
OBJECTIVE:To study the effects of combined use of cefoperazone/sulbactam(CFS),meropenem(MRP)with le-vofloxacin (LVX) on mutant prevention concentration for Acinetobacter baumannii so as to provide a experimental foundation for preventing bacterial drug resistance. METHODS:In the test,there were groups of single use of CFS,MRP and LVX,and groups of combined use of CFS+LVX and MRP+LVX. Double dilution agar method was used to respectively detect minimal inhibitory con-centration (MIC) for standard Acinetobacter baumannii strains ATCC 19606 and 36 clinically isolated strains in all groups,and then the index of fraction inhibitory concentration(FIC)was calculated. Agar dilution method on plates was employed to detect mu-tant prevention concentration (MPC) for Acinetobacter baumannii in all groups,and then corresponding selection index (SI) was calculated. RESULTS:After combined use of CFS or MRP with LVX,synergistic effect accounted for 55%(20/36)and 50%(18/36). For standard strain ATCC 19606,after combined use of CFS+LVX and MRP+LVX,MPC reduced from 32.0 and 4.0 mg/L to 1.8 and 0.8 mg/L;For 36 clinically isolated strains,after combined use of CFS+LVX and MRP+LVX,MPC reduced from 8.0-32.0 and 1.0-2.0 mg/L to 0.25-1.0 and 0.25-0.5 mg/L. SI were all obviously reduced after combination. CONCLUSIONS:The combina-tion of CFS or MRP with LVX can reduce MPC for Acinetobacter baumannii more significantly than the single use,and narrow mu-tant selection window.
