Objective To determine the solubility and apparent oil/ water partition coefficient of sitafloxacin in different solvents. Methods High performance liquid chromatography (HPLC) was used. The column was Dikma Diamonsil C18 (2) (4. 6 mmí250 mm,5 μm). The mobile phase was 0. 05 mol·L-1 KH2 PO4 solution (pH was adjusted with H3 PO4 to 2. 4)-acetonitrile (7030). The column temperature was set at room temperature. The flow rate was 1. 0 mL·min-1 . The detection wavelength was 295 nm and the injection volume was 10 μL. The solubility of sitafloxacin and the apparent oil/ water partition coefficient at pH 2. 0,4. 3,5. 8,6. 6,7. 4,8. 0,10. 0 and 11. 2 were determined. Results The equilibrium solubility of sitafloxacin in water was 0. 44 mg·mL-1 and the apparent oil/ water partition coefficient was 0. 23 (lgP= -0. 64) at (37±2) ℃ . Sitafloxacin has the lowest equilibrium solubility (0. 13 mg·mL-1 ) and the highest apparent oil/ water partition coefficient in pH7. 4 buffer solution system. At pH>10 and pH<5. 8,the solubility of sitafloxacin increased obviously and apparent oil/ water partition coefficient decreased. Conclusion Sitafloxacin is insoluble in water and also poorly soluble in oil,but its solubility could be improved significantly in acidic or alkaline solution.

Magnetic induction hyperthermia becomes a very important tumor treatment method at present. In order to ensure a successful operation, doctors should make hyperthermia treatment planning before surgery. Based on Integration Healthcare Enterprise (IHE) framework and Digital Imaging and Communications in Medcine (DICOM) standard, we proposed and carried out a network workflow integrated with modern medical information systems for the dissemination of information in magnetic induction hyperthermia like accurate accessing patient information and radiology image data, storing processed images, sharing and verifying hyperthermia reports. The results proved that our system could not only improve the efficiency of magnetic induction hyperthermia treatment planning, but also save medical resources and reduce labor costs.

Objective To explore the diagnostic value of detecting serum DJ-1 protein combined with CA125 for epi?thelial ovarian tumors. Methods Double antibody sandwich method and electrochemiluminescence immunoassay were used to determine the serum levels of DJ-1 protein and CA125 in 82 cases of epithelial ovarian tumors and 80 non-ovarian tumor cases (control group). The clinical significance of detecting serum DJ-1 protein combined with CA125 was analyzed. Results The expression levels of DJ-1 and CA125 were significantly higher in ovarian tumor group than those in the con?trol group (P<0.05). The critical value of serum DJ-1 was 6.800μg/L and 6.965μg/L in ovarian cancer group compared with the control group and non-ovarian tumor group. The sensitivity of combined detection of DJ-1 and CA125 was higher than that of any marker alone. Conclusion The detecting serum levels of DJ-1 combined with CA125 are helpful to the diagnosis of ovarian cancer, which can be a good marker of ovarian cancer and may improve the early diagnosis rate of ovarian cancer.

Objective To evaluate the efficacy of intensity-madulated radiotherapy(IMRT) as the primary treatment in nasopharyngeal carcinoma (NPC). Methods Between November 2001 and March 2006,147 newly diagnosed NPC patients were treated with IMRT. The disease was Stage I in 3 patients, Stage Ⅱ in 35,Stage Ⅲ in 67 and Stage Ⅳ in 42. For T1-2 disease,the prescription dose was 70 Gy to the gross tumor volume( GTVnx) and positive neck nodes ,60 Gy to the planning target volume I, and 50-56 Gy to the clinically negative neck. For T3-4 disease,the prescription dose was 74-78 Gy to GTVnx. The local control rate(LC),overall survival (OS), disease-free survival (DFS) and distant metastasis-free survival (DMFS) were estimated by Kaplan-Meier method. Results The 3-year LC, OS, DFS and DMFS of the whole group were 93.2% ,93.5% ,72.6% and 74.4% ,respectively. T stage was a significant predictor of LC and OS. For patients with T1-2 and T3-4 disease,the LC was 100% and 86.9% (P=0.007) and OS was 95.5% and 91.3% (P=0.030), respectively. N stage was a significant predictor of OS, DFS and DMFS(P=0.03,0.004 and 0.0004,respectively). The grade Ⅰ+ Ⅱ and Ⅲ acute toxieities of parotid were 96.6% and 1.4%. The rate of grade Ⅱ xerostomia at 3-month, 6-month, 1-year and 2-year after radiotherapy were 43.0%, 12.0% ,4.9% and 3.2%. Conclusions The treatment results are promising according to our target definition and dose prescription protocol for nasopharyngeal carcinoma.

Objective To investigate the off-label use status in obstetrics ward so as to provide references for carrying out obstetrics pharmaceutical care and promoting safe medication use in pregnant and parturient women. Methods The prescriptions for pregnant and parturient women from January to June, 2015 in obstetrics ward were investigated. According to drug instructions, the off-label drug use of prescriptions of all selected patients was analyzed in the following aspects:the category of off-label drug use, and drugs use information. In addition, a logistic regression was conducted that modeled the odds of receiving an off-label prescription as a function of the following possible risk factors:pregnant, parturient women and the rank of doctors. The clinical results including the unreasonable drug application, abortion rate and birth defect were compared between the off-label drug use and on-label drug use groups. Results Total of 384 patients were selected, and 5330 prescriptions involving 50 drugs were analyzed. The rate of off-label drug use was 68. 5%, 27. 7% and 24. 0% in patients, prescriptions and drug categories, respectively. The main categories of off-label drug use were super solvent use ( 76. 6%) and indication (14. 3%). The top 3 drugs of off-label use were those for urinary and reproductive (56. 2%), alimentary tract (46. 9%) and traditional Chinese medicine (43. 4%). In addition, there was no significant correlation between the risk of off-label drug use and maternal status and the level of doctors. And no significant difference between the two groups in the unreasonable drug application, abortion rate and birth defect was detected. Conclusion The off-label drug use in obstetrics ward is common in this hospital and most of them are supported by clinical evidence. Due to the lack of more authoritative evidence-based medication, the doctors are suggested to use the drug according to provisions of the drug instructions. When off-label drug use is really needed, it should be based on the surpport of evidence basde medicine,so as to ensure the drug safety for pregnant and parturient women and avoid professional risks.
