OBJECTIVE:To provide reference for rational use of antiemetics in cancer patients. METHODS:Two thousand six hundred and sixteen pieces of medical orders of patients receiving antiemetics were collected from oncology department of our hospital via EMRS during Oct. 2015-Jun. 2016. RESULTS:Among 2 616 cases surveyed,1 301 cases conformed to inclusion and exclusion criteria,of which irrational use of drugs were found in 595 cases,760 times in total. Main manifestations were unsuitable drug selection(33.82%),irrational usage and dosage(25.26%),unsuitable drug combination(34.08%)and non-standard medication course(6.84%). The incidence of nausea in female was higher than male,with statistical sighificance(P=0.003),but gender had no significant effect on the incidence of nausea(P>0.05). Age had no significant effect on both nausea and vomiting(P>0.05). The control rate of nausea/vomiting in rational drug use group was higher than irrational drug use group. Average cost of antiemetic treatment of different emetic risk chemotherapy drugs in rational drug use group were all lower than irrational drug use group, indicating therapeutic efficacy could be guaranteed and economic burden was reduced in rational drug use group. CONCLUSIONS:The antiemetic plan should be selected rationally according to emetic risk degree of chemotherapy drugs. Patients receiving combined chemotherapy should select antiemetic plan according to highest emetic risk degree of chemotherapy drugs,and strictly master usage, dosage and duration. At the same time,treatment cost should be considered when selecting antiemetic plan to guarantee the safe, effective,economical and rational use of drugs.

Objective To research the binding specificity of new recombination toxin LHRH-PE40 and LHRH receptor on the surface of human colon carcinoma cell line Lovo and the mechanism of anti-proliferation,and determine the apoptosis.Methods Lovo cells were analysed by LHRH-PE40 marked with()~(125)Ⅰ;the cytocidal effect of the anti-tumor was evaluated by MTT assay,and the apoptotic rate was analysed by flow cytometry.Results Lovo cells had the binding of aglucone and receptor.Half lethal dose of human colon carcinoma cells Lovo with LHRH-PE40 was 0.24 mg?L~(-1).The apoptotic rate was increased when the LHRH-PE40 concentration was ranged from 0.1 to 10 mg?L~(-1)(P

OBJECTIVE:To investigate the characteristics and influential factors of adverse drug reactions(ADRs)of docetax-el in our hospital,and to provide suggestions for clinical rational drug use and individualized administration. METHODS:Medical records of patients receiving anti-tumor chemotherapy were extracted from hospital information system(HIS)of our hospital during Apr. 2014 and Oct. 2015,and Docetaxel related ADR reports were collected and comprehensively analyzed by retrospective classi-fied statistics. RESULTS:Among 417 cases,105 cases of docetaxel related ADR were reported. There were 69 patients aged 50-69 with highest ADR frequency. The ADR incidence of female patients was higher than that of male patients (29.29% vs. 19.66%). The incidence of docetaxel related ADR and arrest of bone marrow increased as the increase of drug dosage;the incidence of breast cancer ADR was the highest (46.03%),followed by lung cancer (37.25%) and gastric cancer (25.00%). The incidence of docetaxel+platinum chemotherapy plan ADR was the highest (35.10%). Main organs/system involved in ADR was hematological system (55.65%). CONCLUSIONS:The individual difference of docetaxal related ADR are great and affected by several factors. Individual physical condition of patients should be taken into consideration as early as possible,which can reduce the incidence of ADR and promote clinical rational drug use.

Objective To investigate the clinical application of 3.0 T mobile iMRI and neuronavigation in the microsurgical operation for the high grade gliomas in brain functional area.Methods The clinical data of 47 cases which were operated from April,2012 to August,2014 assisted by intraoperative magnetic resonance and neruonavigation system were analyzed retrospectively,including 19 cases of near the frontal motor areas,21 cases of closed to the dominant hemisphere language areas,and 7 cases of involved multiple lobes of the brain.The operative plans were made before the operative day using 3.0 T iMRI for T1-MPRAGE plain and enhancement magnetic resonance imaging sequence,diffusion tensor imaging (DTI) sequence and blood oxygenation level dependent functional MRI (BOLD-fMRI) sequence scanning.Before the start of operation,the margin of the tumor was marked on the scalp,and removed the tumor under the microscopy,according to the need 1-4 iMRI plain scan and enhanced scan were applied to reconstruct the real-time imaging of the residual tumors and corticospinal tract,and gained once more chances to remove the tumor repeatedly,until the tumor was removed totally,accurately and safely.Results The total resection rate increased from 63.8％ (30/47) to 95.7％ (45/47) by repeated resection,and 2 cases (4.3％ lesions) with subtotal resection.The dysfunction of motion and the language barrier got worse in 4 patients (8.5％).No cases with sever complication such as death and severe disability after operation.There were no intracranial hemorrhage,infection and other adverse events.Patients were followed up with nervous system symptoms and head MRI,the follow-up period was 3 months-2 years.Twenty-eight cases (59.6％) ob-tained good clinical efficacy;the dysfunction of motion and the language barrier got worse in 4 cases (8.5％);the symptoms and tumors recurrenced in 15 cases (31.9％).Conclusion The 3.0 T mobile iMRI system combined with functional neuronavigation can accurately display the relationships among the motor and language cortex,tumors and white matter fiber bundles real-timely.The extent of the tumor resection can be assessed accurately by real-time images provided by iMRI,and the residual tumor have chames to be resected repeatedly,until the tumors were resected totally before operation finished.The iMRI system can correct intraoperative brain shift timely.The total resection rate can be improved safely and accurately by one or more times resection.

Objective: To discuss the effect of group counseling on the self-control of male adolescents drug addicts. Methods: 90 male adolescents drug addicts who accepted group counseling were identified as test group, while another 97 male adolescents drug addicts who accepted no intervention as control group. Self Control Scale developed by Grasmick in 1993 was used to assess the outcome. Results: The total scores in the test group decreased from 52.06?6.67 to 47.68? 8.67, and all dimension scores were at significant level (P

Objective To evaluate the effect of neuraxial and general anaesthesia for total joint arthroplasty by meta-analysis.Methods We searched online Pubmed,Web of science,Cochrane li-brary,CNKI,CBM and searched the literature of the Chinese series journals.All randomized controlled trials (RCT)that met their standards of neuraxial and general anaesthesia for total joint ar-throplasty were collected.The quality of trials was strictly assessed.RevMan 5.3 software was used for data analysis.Results Twenty-one RCTs involving 1 874 cases were included.Compared with general anaesthesia,the pooled data showed that the neuraxial anaesthesia significantly reduced blood loss (WMD=-97.52,95% CI = - 1 73.60-- 21.44,P = 0.01 ),associated with lower risk of deep vein thrombosis (RR=0.68,95%CI=0.48-0.95,P =0.02)and pulmonary embolism (RR=0.58, 95%CI=0.35-0.91,P =0.03),decreased the number of postoperative nausea and vomiting (RR=0.74,95%CI=0.60-0.92,P =0.008).Subgroup analysis showed that compared with general anaes-thesia,the neuraxial anaesthesia associated with lower risk of deep vein thrombosis (RR=0.5 1,95%CI=0.38-0.69,P < 0.000 01 )and pulmonary embolism (RR = 0.34,95% CI = 0.18-0.65,P =0.001)in patients who did not receive chemical antithrombotic prophylaxis.Conclusion Neuraxial anaesthesia seems to improve the outcome of patients undergoing total joint arthroplasty and reduce postoperative complications.
