Objective:To understand the situation of time limitation prescriptions of outpatients in our hospital. Methods:A ret-rospective study was conducted on 1 107 time limitation prescriptions from July 1st to 31th in 2015. Results: There were 1 107 time limitation prescriptions in 16 063 prescriptions (6. 89%), which included 902 patients, and among them, there were more than one time limitation prescription in one day for one patient. As the increase of age, the number of patients with time limitation prescriptions was increased. The number of time limitation prescriptions with the sum between 101 and 200 yuan was the most (34. 51%). The di-agnosis of top 10 of the drugs according to the doctor’ s advice and the actual top ten was substantially consistent, and among them, half were Chinese patent medicines. Conclusion:Time limitation prescriptions are the products of medical insurance policy. The man-agement of time limitation prescriptions can’ t be only defined as the quantity superposition of drugs, and it is necessary to generate in-dividualized strategy according to the properties of diseases, drugs and patients in order to obtain more reasonable management strate-gies, and the ultimate purposes are benefiting patients and obtaining more rational distribution of medical resource.

Objective To investigate the effects of partial prostatic capsula and surrounding striated sphincter sparing surgery on the function of intestinal orthotopic neobladder. Methods Total cystectomy and orthotopic intestinal neobladder was performed in 23 male patients with invasive bladder cancer. The patients were divided into classical cystectomy group (n=10) and modified cystectomy group (n=13).In the classical group the prostate was removed completely and the residual urethra was anastomosed with the neobladder using interrupted suture.In the modified group transurethral resection of the prostate preceded the cystectomy,and the prostatic capsula below the verumontanum with its surrounding striated urethral sphincter was retained.The neobladder was anastomosed with the residual capsula using continuous suture.The function of the neobladder in the 2 groups was evaluated and compared. Results The pathological classification of the 23 patients was as follows:T 2aN 0M 0,13 cases;T 2bN 0M 0,6;T 1N 0M 0,1;T 3aN 0M 0,1;T 3bN 1M 0,1;T 4aN 0M 0,1.The patients were followed up for 3 to 40 months(mean,15.7 months).In modified group,11 patients survived disease-free and 2 survived with metastasis.All the 13 patients voided well with residual volume of 0 to 70 ml.Complete urinary continence was achieved in 12 patients and the remaining one had nocturnal incontinence.In classical group,10 patients survived disease-free;of them 7 voided well with residual volume of 10 to 100 ml and the other 3 needed intermittent catheterization because of their residual urine being up to 100 to 250 ml.Complete continence was achieved in 7 patients and the other 3 were incontinent(1 with incontinence day and night,2 with nocturnal incontinence). Conclusions Partial prostatic capsula and its surrounding striated sphincter sparing surgery can improve the continence and voiding of the orthotopic neobladder.$$$$

Objective:To discuss the causes and characteristics of drug-related problems(DRPs) of antiepileptic drugs by the in-vestigation of antiepileptic drugs' use in our hospital in order to provide reference for the rational clinical application of antiepileptic drugs. Methods:A retrospective analysis on 878 inpatients' records including antiepileptic drug application in our hospital from Janu-ary to December 2016 was carried out. The gender,age,etiology,application of antiepileptic drugs,usage,combination and adverse reactions were statistically analyzed in order to analyze the epidemiological characteristics of antiepileptic drugs in our hospital. At the same time,the necessity,safety and validity of the DRPs of antiepileptic drugs were studied by the international generic Spanish drug related research method(Granada-Ⅱclassification method). Results:Among the 878 cases,most were male patients(60.71%) and the proportion of patients over 50 years old was 69.02%. Patients with cerebrovascular diseases accounted for the most (323 cases, 36.79%),and 7 varieties of antiepileptic drugs were involved, and sodium valproate was with the largest proportion (489 cases, 51.75%). The DRPs were classified as DRP2(49 cases),DRP5(22 cases) and DRP6(8 cases). Conclusion:In view of the epi-demiological characteristics of antiepileptic drugs and DRPs specific issues in clinical applications, clinical pharmacists need to strengthen the intervention in DRPs of antiepileptic drugs in order to promote the safety and reasonability of clinical application.

Objective: To explore the effect of clinical pharmacists participating in the clinical pharmacy work in neurosurgery de-partment and the influence on the rational drug use index. Methods: A retrospective analysis on the monthly drug proportion, antibac-terial drug utilization rate and intensity, and the other indicators before and after the intervention performed by clinical pharmacists in neurosurgery department was carried out, and the consumption sum, DDDs and medical records were statistically analyzed in April and June 2017. Results: After the intervention, the proportion of medicine, hospital days per capita, use rate and intensity of antimicrobial drugs, and the other rational drug use indices were significantly improved in neurosurgery department, and the differences in the indi-ces before and after the intervention were significant (P<0. 01). Conclusion: Consultation practice of clinical pharmacists in neuro-surgery department can effectively assist and guide the clinical treatment and improve the level of rational drug use.

Objective To investigate the risk factors predicting pathology grade upgrading after radical prostatectomy using the 2014 International Society of Urologic Pathology (ISUP) grading system.Methods A total of 205 patients who underwent biopsy and radical prostatectomy from January 2017 to December 2018 were reviewed retrospectively.The median and range of the patients' age,PSA level,prostate volume,number of biopsy core examined,Gleason score and ISUP grade were 66 (45-81) years old,17.16(0.89-1254.00)ng/ml,36.4(4.1-152.1) rnl,10(1-15),7(6-10),and 3(1-5) respectively.The patients were divided into group of upgrading ISUP grade and group without upgrading ISUP grade.Multivariate Logistic regression analysis and receiving operating characteristic curve analysis were performed to identify predictors of ISUP upgrading and determine the optimal cut off value respectively.Result The median and range of Gleason score and ISUP grade after radical prostatectomy were 7 (6-10),and 3 (1-5) respectively.The radical prostatectomy ISUP grade upgraded in 73 (35.6％) out of 205 cases when compared with biopsy ISUP grade.Radical prostatectomy ISUP grades were concordant in 91 cases (44.4％) and downgraded in 41 cases(20.0％).Of 101 with biopsy ISUP grades less than or equal to 2,the ISUP grade of radical prostatectomy upgraded in 58 cases (57.4％),while radical prostatectomy ISUP grade upgraded in only 18 (26.9％) of 67 patients with biopsy ISUP grades of 3 or 4.Biopsy ISUP grades represent an independent predictor for ISUP grade upgrading after radical prostatectomy (OR =0.496,P ＜ 0.001).Conclusion Patients with biopsy ISUP grades less than or equal to 2 are at great risk of ISUP grade upgrading after radical prostatectomy.

Objective:To evaluate the efficacy and safety of switch from prednisone (AA+ P) to dexamethasone (AA+ D) in metastatic castration-resistant prostate cancer patients (mCRPC) progressing on abiraterone plus prednisone.Methods:Between November 2016 and December 2019, 46 mCRPC patients were switched to AA+ D after progression on AA+ P at Sun Yet-sen University Cancer center. Median age was 72 years(50 to 89 years), with median androgen deprivation therapy (ADT) duration 14.6 months(2.1 to 168.5 months). PSA level at the time of diagnosis, the initiation of AA+ P treatment, the time of switch were 258.9 ng/ml, 56.6 ng/ml, 25.1 ng/ml, respectively. 42 (91.3%), 12(26.1%), 7(15.2%) patients had bone metastasis, lymph node metastasis, visceral metastasis, respectively. 28 patients had Gleason score ≥8, and 11 patients had Gleason score<8. The primary endpoint was progression free-survival (PFS). Secondary endpoints included PSA response rate of PSA decline ≥50% and ≥30% and safety. Patients were divided into different risk level groups according to PSA level at the time of switch and PFS on AA+ P.Results:The median follow-up of 46 patients was 4.9 months, 40 patients progressed at the last follow-up, the treatment was terminated in 1 patient because of cerebral infarction, 5 patients were still on the treatment of AA+ D. Median PFS on AA+ D of 46 patients was 3.7 (1.6-24.1) months. A total of 12 (26.1%) patients showed a PSA decline≥50% after treatment with AA+ D, and 21 (45.7%) patients showed a PSA decline ≥30%. The median PFS was 8.5 (2.7-24.1) and 3.0 (1.6-17.8) months for patients with PSA decline≥50% and PSA didn’t decline ≥50%, respectively. Four factors below were significantly associated with a longer PFS on AA+ D after steroid switch in univariate analysis: lower PSA level at the time of switch (<30 ng/ml, HR=0.30, 95% CI 0.14-0.64, P=0.002), longer ADT sensitivity duration (≥18 months, HR=0.55, 95% CI 0.28-1.06, P=0.045), longer AA+ P treatment PFS (≥8 months, HR=0.36, 95% CI 0.18-0.72, P=0.004), and greater PSA decline on AA+ D (≥50%, HR=0.30, 95% CI 0.17-0.75, P=0.007). The above mentioned factors were also independent prognostic factors associated with better PFS on AA+ D after steroid switch in multivariate analysis. Treatment with AA+ D was well tolerated in all patients, with no grade 3/4 toxicity reported. Conclusions:Switching from prednisone to dexamethasone is effective and safe in mCRPC patients progressing on abiraterone plus prednisone. Patients with lower PSA level at the time of switch, longer ADT sensitivity duration, longer AA+ P treatment PFS and greater PSA decline on AA+ D might gain better efficacy.
