ABSTRACT
Objective:To analyze the hemostatic drugs use for orchidopexy in children during the perioperative period to promote the rational use of hemostatic drugs for orchidopexy in children. Methods:The perioperative prophylactic use of hemostatic drugs for orchi-dopexy in 138 children from June 2015 to December 2016 was retrospectively analyzed. The difference of clinical data and outcome indica-tors were compared between hemostatic drugs group(drug group) and without hemostatic drugs group (control group),and the rational use of hemostatic drugs in the drug group was analyzed. Results:The operation time,amount of bleeding and the length of hospital stay showed no statistical differences between the groups during the perioperative period in our hospital. There were 44.9% of children under-going orchidopexy treated with hemostatic drugs,and the unreasonable rate was 51.6% in the drug group. Among them,35.5% of chil-dren were with too long medication time,11.3% of children were with unreasonable initial treatment time, and 4.8% of children were with single overdose. Conclusion:The perioperative hemostatic drugs use for orchidopexy in children still has several problems, inclu-ding excessive medication duration,inappropriate administration time and single overdose etc,and clinicians should pay attention to above situations.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
OBJECTIVE: To discuss the correlation between the consumption of antibacterials and the antibiotic resistance of Pseudomonas aeruginosa(PA) in our hospital.METHODS: The total antibacterial consumption expressed as defined daily doses(DDDs/day/100 persons) as well as the synchronous antibiotic resistance rate of PA were computed and the correlation beween the them was analyzed.RESULTS: The resistance rates of PA to cefepime,gentamycin and ciprofloxacin were positively correlated with the consumption of ciprofloxacin.A significant positive correlation was noted between the resistance rates of PA to gentamycin and imipenem cilastatin and the consumption of imipenem.The resistance rates of PA to ceftazidime and ceftriaxone were positively correlated with the consumption of piperacillin/tazobactam.The resistance rates of PA to amikacin and gentamycin were positively correlated with the consumption of amikacin and gentamycin respectively.CONCLUSION: A positive correlation was noted between antimicrobial consumption and antibiotic resistance of PA.
ABSTRACT
OBJECTIVE: To prepare clomipramine hydrochloride sustained release tablet and study its in vitro release rate.METHODS: Orthogonal experiment was carried out to optimize the formulation and the preparation was prepared taking by the formula dosage of HPMC,lactose and amylum pregelatinisatum as factors and the in vitro release rate as index.The in vitro drug release rate was investigated as well.RESULTS: The optimal formulation was as follows: HPMC 45 mg,lactose 35 mg,and amylum pregelatinisatum 40 mg.The preparation prepared in the optimal formulation had a sustained release of 24 h and the release behavior of the tablets followed the zero order equation.CONCLUSION: The formula of the sustained release tablets is reasonable and which had satisfactory sustained release efficacy.
