A specific and sensitive GC - MS method for assaying Borneol in the serum of rats medicated orally with compound Danshen dropping pill was developed. Naphthalene was used as the internal standard, the dectection was performed by SIM. The calibration curve was linear in the range from 0.00505 to 40. 1 ?g/mL, the detectable limit of this method was 1 ng/mL. The extraction recovery of Borneol was 72.82% - 86.77%. The RSD of within - day and day - to - day was less than 2.76% and 1.93% respectively. The results showed that this method was simple, sensitive, accurate and good reproducibility , and can be used in further pharmacokinetic study of Borneol in danshen Dropping pill.

Objective To explore the application of washing fluid in the prevention of postoperative incision infection of colorectal cancer. Methods 350 patients with colorectal cancer underwent colorectal surgery from Jan. 2012 to Dec. 2015 were randomly divided into three groups: sterile saline, 0.50% metronidazole, 0.50% Povidone-iodine solution group, while part of the rinse liquid heated to 37 ~38℃ before use, then record the operation time, surgical site, postoperative incision infection, incision infection, timely delivery statistical analysis was performed by using single factor analysis and logistic multivariate regression analysis. Age, operation time, surgical site, type of irrigating fluid and temperature of flushing fluid were analyzed statistically. Results The incision infection rate of the patients ≥60 years old and the operation time ≥2 h was higher than the age <60 years, and the operation time was less than 2 h, P < 0.05, the difference was statistically significant; 0.50% metronidazole, 0.50% Povidone-iodine solution group, the infection rates of 0.50% metronidazole and 0.50% povidone-iodine group were 7.69% and 8.55%, respectively, which were significantly lower than those of the saline group 16.38% The infection rate of the rinsing fluid after heating was 7.22% and 14.71%, respectively, lower than that of the normal temperature rinsing solution (P < 0.05), the difference was statistically significant. Conclusions The risk factors of incisional infection in colorectal cancer patients with colorectal cancer were : ≥60 years of age and ≥2 h of operation, while 0.50%metronidazole, 0.50% povidone-iodine solution and heated washing fluid were protective factors. It can be applied to prevent incision infection after laparoscopic surgery.
