Objective Oridonin is a poorly water soluble drug with low bioavailability.The study aimed to prepared improve the dissolution rate of oridonin by preparation of oridonin solid dispersion with poloxamer. Methods The oridonin solid dispersion was prepared by dissolvent method with poloxamer188 as the carrier and determined by DSC and powder X-ray diffraction.The dissolu-tion rates in different pH dissolution mediums of pure drug, physical mixture and solid dispersion were determined by HPLC method. Results Oridonin exists as an amorphous state in the solid dispersion.Compared with the pure drug and physical mixture, the orido-nin solid dispersion was improved greatly without the pH influence on the drug release.The dissolution rate of oridonin solid dispersion in water, pH 6.8 PBS and pH 1.2 HCl were (92.6 ±4.2)%, (93.1 ±3.5)%and (94.4 ±2.9)% respectively. Conclusion Taking inpoloxamer188 as the carrier, the oridonin solid dispersion has successfully developed its dissolution rate.

Objective To investigate the preventive effect of fibroblast growth factor on infection after tooth extraction among type 2 diabetes mellitus patients. Methods 76 patients with infection prevention were treated with basic fibroblast growth factor, and 90 patients in the control group(n= 324). The intervention group was treated with basic fibroblast growth factor and treated with recombinant bovine basic fibroblast growth factor gel. The routine treatment group was treated with routine rinsing liquid for disinfection to prevent infection. Follow-up observation of infection after 1 week. Results In the group of basic fibroblast growth factor, the infectious rate was 2.63%, which was not significantly lower than that of the control group. The level of white blood cells in the group treated with basic fibroblast factor was (6.67±1.08)×109/L, which was significantly lower than that of the control group. The CRP level was (90.33±12.95) mg/L, which was significantly lower than that of the control group Group level (P<0.05). The incidence of fibroblast infection was 2.7% in men and 6.38% in control group. Although there was no significant difference between the two groups, the difference in the total WBC count and CRP level between the two groups was significant different (P<0.05). The group which use of basic fibroblast growth factor, the total white blood cell count and CRP level of the infection prevention intervention group were significantly lower than the control group (P<0.05). Similar results were found in women. Conclusion Fibroblast growth factor can be used to prevent postoperative infection, and achieve satisfactory results.
