Objective To investigate the influence of neoadjuvant chemotherapy on the occurrence of postoperative nausea and vomiting ( PONV) after radical mastectomy. Methods A total of 286 breast cancer patients, aged 18-60 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective modified radical mastectomy under general anesthesia in our hospital, were divided into either non?chemotherapy group ( n=106 ) or neoadjuvent chemotherapy group ( n=180 ) . General anesthesia was induced with iv propofol 2 mg∕kg, rocuronium 0. 6 mg∕kg and sufentanil 0. 2 μg∕kg. The patients were endotracheally intubated. The concentration of sevoflurane inhaled was adjusted according to the value of bispectral index, and bispectral index value was maintain at 40-50. Ondansetron 8 mg and flurbiprofen axetil 100 mg were injected intravenously at 30 min before the end of surgery. If vomiting occurred for 2 consecutive times, and continuous nausea and vomiting appeared from the time point after extubation to 24 h after surgery, and the patients required treatment, rescue medication was used. The occurrence and severity of PONVwithin 24 h after surgery and requirement for rescue medication were recorded. Results Compared with non?chemotherapy group, the incidence of PONV within 24 h after surgery and requirement for rescue medication were significantly increased, and the severity of PONV was aggravated in neoadjuvent chemotherapy group (P<0.05). Conclusion Neoadjuvant chemotherapy before surgery can increase the risk and severity of PONV after modified radical mastectomy.

Herpetin (HPT) is an active monomer constituent isolated from lignanoid in seeds of Herpetospermum caudigerum. HPT shows inhibitory effects in hepatic injury and HBV-DNA and the replication. In the study, we successfully prepare herpetin liposomes by film dispersion method for the first time. The prescription process was optimized, with the entrapment efficiency as the index. According to the optimized prescription, the mass ratio of HPT: phospholipids: cholesterol was 2.44:78.05: 19.51, the hydration and de-molding process was performed with 0.5% F68 solution at 50 degrees C, and the water-bath ultrasonic time was 20 min. The HPT liposomes prepared by this method showed an average entrapment efficiency of (94.50 +/- 2.15)% and a particle size of (119.2 +/- 10.7) nm, which was consistent with the trial expectations and will lay a solid foundation for the hepatic targeting delivery system in future.

High-performance liquid chromatographic coupled with variable wavelength detection (HPLC-VWD) has been developed for simultaneous determination of 5 analytes including ellagic acid, quercetin, kaempferol-3-O-beta-D-rutinoside, tiliroside and kaempferol, and high-performance liquid chromatographic with an evaporative light scattering detector (HPLC-ELSD) has been established to determine goshonoside-F5 in extract of Rubi Fructus. Chromatographic separations were carried out on an Agilent ZORBAX SB-C18 column (4.6 mm x 250 mm, 5.0 microm). All calibration curves of reference standards revealed good linearity (R2 > 0.999 5) within the concentration ranges tested. The method limits of detection ranged 0.297-90.144 ng and the method limits ofquantitation ranged 0.990-300.480 ng, respectively. Recoveries of 6 analytes were from 97.11% to 101.7%, with RSD less than 2.1%. The result shows that amounts of the 6 analytes in the samples from 16 localities were found to be different. The higher latitude of growing environment, the more ellagic acid in herb. The content of total flavonoids in sample from east localities were higher than that in middle and west localities, and the content of goshonoside-F5 in Bozhou, Anhui province was higher than others. This method was found to be simple, accurate, sensitive with good repeatability. Those results might serve as a sound foundation for further study, quality control and application of Rubi Fructus.

Objective:To investigate the values of genetic polymorphisms of excision repair cross-complementation group 1 (ERCC1), thymidylate synthase (TS), glutathione-S-transferase P1 (GSTP1) and methylenetetrahydrofolate reductase (MTHFR) in predicting the prognosis of advanced esophageal cancer patients treated with cisplatin/fluorouracil chemotherapy.Methods:One hundred and seven patients with advanced esophageal cancer were enrolled in this study, 98 of which were eligible for analysis. All patients received cisplatin/fluorouracil chemotherapy repeated every three cycles. Genetic polymorphisms examined herein included those in the genes coding ERCC1, TS, GSTP1 and MTHFR. Then the relationships between genetic polymorphisms and response rate (RR) and progression free survival (PFS) time were analyzed. Results:The patients with A/A or A/C genotype in ERCC1-C8092A had a higher response rate and longer PFS than the patients with C/C genotype (P=0.010,P=0.008);the patients with 2R2R or 2R3C or 3C3C genotype in TS-5'UTR had a higher response rate and longer PFS than the patients with 2R3G or 3C3G or 3G3G (P=0.007,P=0.018). There was no significant relationship between RR and PFS and other genetic polymorphisms. Conclusion:The advanced esophageal cancer patients with A/A or A/C genotype in ERCC1-C8092A and/or 2R2R or 2R3C or 3C3C genotype in TS-5'UTR were more sensitive to cisplatin/fluorouracil chemotherapy.
