RESULTS Totally 14 328 戒。电话：023-63625666。E-mail：jiayuntaomail@hospital.cqmu.edu.cn ARF reports of 4 kinds of β-blockers were retrieved within the ·1380· China Pharmacy 2022Vol. 33 No. 11 中国药房 2022年第33卷第11期 narrow sense of “acute renal failure ”in SMQ term set ，of which men （6 964）were more than women （6 206）. The age of patients was mainly concentrated in the middle-aged and elderly （≥45 years old ），and serious adverse events accounted for 77.23％. The results of signal retrieval based on SMQ term set showed that ROR values and 95％ confidence intervals of metoprolol ，bisoprolol， atenolol and nebivolol detected by ROR method were 2.58（2.51，2.65），5.30（5.14，5.47），2.80（2.69，2.91）and 3.28（3.04， 3.53）respectively. The signal components （IC）detected by BCPNN method and the lower limit of IC were 1.29（1.25），2.26 （2.22），1.42（1.36）and 1.64（1.53）respectively，suggesting suspicious signals were detected in these four kinds of β-blockers associated ARF. The results of signal detection based on PT level terms showed that 37 positive signals were detected by ROR method，38 positive signals were detected by BCPNN method ，and 36 suspicious signals were detected by the two methods at the same time. For each drug ，12 suspicious signals of metoprolol were detected at the same time ，9 suspicious signals of bisoprolol and atenolol were detected at the same time ，and 6 suspicious signals of nebivolol were detected at the same time ；the number and type of signals were different among the 4 kinds of drug. CONCLUSIONS Four kinds of β-blockers may cause ARF. Compared with metoprolol and atenolol ，bisoprolol and nebivolol have strong statistical correlation with ARF ，suggesting that medical personnel should pay attention to the possible renal related adverse reactions of these drugs in the process of clinical use.

Mining and Evaluation of Post-marketing Safe Alert Signals of Pegaspargase and L-asparaginase Based on BCPNN Method / 中国药房

OBJECTIVE： To mine and evaluate the post-marketing safety alert signals of pegaspargase （PEG-ASP） and L-asparaginase （L-ASP），and compare the safety differences between them ，so as to provide reference for clinical safe and rational drug use. METHODS ： The adverse drug event （ADE） reports of PEG-ASP and L-ASP issued by FDA adverse event reporting system from Jan. 1st，2004-Jun. 30th，2020 were retrieved. BCPNN method was used to mine the safety signals of these two drugs under the condition that the lower limit of information component （IC－2SD）＞0 and the number of events ≥3. The medium and strong signals of two drugs with IC －2SD≥1.5 were evaluated and compared in 8 system organ class，such as gastrointestinal system ，hepatobiliary system ，blood and lymphatic system ，blood vessels and lymphatic vessels ， nervous system ，immune system ，metabolism and nutrition ，various examinations. IC value of specific ADE signal and its 95％ confidence interval were analyzed by time scanning spectrum. RESULTS & CONCLUSIONS ：The reports of PEG-ASP and L-ASP as suspected drugs were 2 324 and 3 824；67 and 68 medium and strong signals were included ，respectively. In gastrointestinal system，the common strong signal of PEG-ASP and L-ASP was necrotic pancreatitis. In hepatobiliary system ，both of them showed strong signal in venoocclusive liver disease ，and this ADE was not included in the drug instruction. In blood and lymphatic system ， common strong signals of the two drugs were febrile neutropenia ，coagulation disorder ，neutropenia and febrile bone marrow regeneration disorder ；in blood vessels and lymphatic vessels ，in addition to haemodynamic instability ，IC values of other signals of L-ASP were higher than those of PEG-ASP. In nervous system ，IC values of other signals of L-ASP were higher than those of PEG-ASP except for intracranial haemorrhage. In immune system ，anaphylactic reaction was a medium signal for L-ASP but was a strong signal for PEG-ASP. In metabolism and nutritional diseases ，except for tumor lysis syndrome ，IC values of other signals of L-ASP were higher than those of PEG-ASP. The results of time scanning spectrum showed that the signals of necrotic pancreatitis and coagulation disorder of PEG-ASP were stable ，while the signals of veno occlusive liver disease and hypersensitivity were unstable and needed to be observed ；above four signals of L-ASP were stable signals. When using PEG-ASP or L-ASP clinically ， close attention should be paid to the safety problems such as hypersensitivity ，coagulation disorder ，thrombosis，necrotic pancreatitis，venoocclusive liver disease and hypoproteinemia.

METHODS ：The abnormal female reproductive system haemorrhage reports induced by 4 kinds of NOACs as “dabigatran etexilate ”，“rivaroxaban”，“apixaban”and“edoxaban”were used as the first suspected dugs to collected from FDA adverse event reporting system （FAERS）database during Jan. 1st，2004-May 31st，2019. The report odd ratio （ROR） method was used to detect the signal of abnormal female reproductive system haemorrhage induced by NOACs. RESULTS ：A total of 2 658 adverse events related to abnormal female reproductive system haemorrhage were collected from FAERS database ， involving 330 reports of dabigatran etexilate ，2 049 reports of rivaroxaban ，267 reports of apixaban ，and 12 reports of edoxaban. The abnormal female reproductive system haemorrhage caused by dabigatran etexilate ，apixaban and edoxaban mainly occurred in patients aged 75 and older ，accounting for 37.27％，36.70％ and 58.33％ respectively；that of rivaroxaban mainly occurred in patients with 45-64 years old ，accounting for 33.04％. The incidence of severe adverse events （SAE）induced by dabigatran etexilate，rivaroxaban，apixaban and edoxaban were 96.36％，84.53％，47.19％ and 58.33％，respectively. All of patients in the included reports were mainly hospitalized and hospitalization stay wa s prolonged ，accounting for 64.78％，90.01％，86.51％ and 71.43％ ，respectively. A total of 12 suspected signals were detected，involving cervix uteri ，fallopian tube ，ovary，pelvis cavity，uterus，vagina，urinary tract ，etc. Among them ，there were 11 positive signals of rivaroxaban ，and the bleeding events were concentrated in vaginal hematoma [ROR ＝12.07， 药。95％CI（8.51，17.12）]，postmenopausal hemorrhage [ROR ＝ 9.89，95％CI（8.31，11.77）]，pelvic hematoma [ROR ＝7.68，95％CI（5.66，10.43）]. There were 4，4 and 2 suspicious signals for dabigatran etexilate ，apixaban and edoxaban. The main bleeding events of both apixaban [ ROR＝5.18，95％CI（1.81，5.85）] and edoxaban [ROR ＝48.19，95％CI（6.76，343.77）] were vaginal hematoma ；dabigatran etexilate-induced pelvic hematoma [ROR ＝ 12.56，95％CI（8.92，17.70）] had the strongest signal ，followed by urinary tract bleeding [ROR ＝5.41，95％CI（3.34，8.76）] and pelvic hemorrhage [ ROR＝2.53，95％CI（1.88，3.40）]. CONCLUSIONS ：Totally 4 kinds of NOACs can cause abnormal female reproductive system haemorrhage ，and the incidence of SAE is high ，of requiring hospitalization or prolonging hospitalization time. The risk of haemorrhage in rivaroxaban is the highest ，usually manifesting as vaginal hematoma ，postmenopausal hemorrhage and pelvic hematoma. Dabigatran etexilate mainly induce pelvic hematoma ，while apixaban and edoxaban are mainly cause vaginal hematoma.

OBJECTIVE:To investigate the general regularity and characteristics of propylthiouracil (PTU)-associated small vasculitis (ASV),and to provide reference for rational drug use in the clinic. METHODS:ADR/ADE case reports of PTU-ASV published during 1990-2016 were retrieved. The data of 118 ADR cases were analyzed statistically. RESULTS:The incidence of PTU-ASV was higher in female and was highest in 18-59 age group. Drug dose of 87 patients were within 600 mg/d,and the inci-dence of PTU-ASV was the highest within 1-5 years after medication. Main clinical manifestations were renal and lung function in-jury. After drug withdrawal,59 patients received hormone therapy,and 30 patients received hormone combined immunosuppressive agent. Finally,115 patients were recovered and 3 patients died. CONCLUSIONS:In older to reduce or avoid the occurrence of ADR,it is necessary to regularly check antineutrophil cytoplasmic antibody related indexes and evaluate the symptoms of ADR.

The factors influencing serum trough concentration of vancomycin in pediatric patients with severe gram-positive cocci pneumonia / 临床儿科杂志

Objective To explore the factors influencing serum trough concentration of vancomycin in pediatric patients with severe gram-positive cocci pneumonia. Methods The general information, the biochemical test results, and plasma concentration of vancomycin were collected from 93 pediatric patients with severe gram-positive cocci pneumonia. The relative factors influencing trough concentration of vancomycin were analyzed retrospectively. Results With the dosage of 40-60 mg/(kg·d), serum trough concentration of vancomycin were between 10-20 mg/L in 26 patients, <10 mg/L in 54 cases, ≥20 mg/L in 13 cases. The ALT, AST, GFR, and γ-GT were significantly different among three groups (P<0.05); the 10-20 mg/L group had the highest levels of AST and γ-GT, the ≥20 mg/L group had the highest level of ALT and the lowest level of GFR. Multiple linear regression analysis showed that GFR was negatively linearly correlated with the serum trough concentration of vancomycin (R2=0.039, P<0.05). The median serum trough concentration of vancomycin in pediatric patients with GFR≥90, 60–90, 30–60 mL/(min·1.73m2) were 8.66, 18.21, 8.45 mg/L respectively, and the difference is statistically significant (P<0.05). Conclusions The serum trough concentration of vancomycin is negatively linearly correlated with GFR in pediatric patients with severe gram-positive cocci pneumonia. The patients with impaired renal function are easier to reach the target serum trough concentration of vancomycin. Clinical use of vancomycin should follow the low doses in the range the guideline recommended, and the serum trough concentration should be closely monitored.

Excavation and Evaluation of Security Alert Signals of Linezolid Based on Reporting Odds Ratio Method / 中国药房

OBJECTIVE:To excavate and evaluate the security alert signals of linezolid after marketing,and to provide refer-ence for rational drug use in clinic. METHODS:The reporting odds ratio(ROR)method was used to excavate the security alert signals from the adverse drug events(ADE)data in the OpenFDA platform of FDA during second quarter of 2004-2016. The low-er limit of 95%CI >1 was regarded as suggestive of ADE alert signal. RESULTS:A total of 6828534 reports were extracted, among which there were 7224 reports mainly induced by linezolid. Top 10 ADE reports were thrombocytopenia,drug interac-tion,thrombocytopenia,nausea,anaemia,serotonin syndrome,diarrhoea,pyrexia,drug ineffective,vomiting. After the detec-tion of top 200 ADE reports by ROR method,120 signals related to 18 system organ class(SOC)were identified. Top 5 ADE sig-nals in turn by SOC were medical examination,nervous system disorders,blood and lymphatic system disorders,metabolism and nutrition disorders,cardiac disorders. The high risk signals with clinical reference value included 42 cases of optic neuropathy (ROR=56.33),350 cases of serotonin syndrome(ROR=52.86),162 cases of lactic acidosis(ROR=18.30),31 cases of endo-carditis (ROR=15.38),566 cases of thrombocytopenia (ROR=14.29),122 cases of bone marrow failure (ROR=14.20),261 cases of panhematopenia (ROR=11.92),86 cases of disseminated intravascular coagulation (ROR=10.91),58 cases of toxic epidermal necrolysis(ROR=9.06),etc. As for ADE reports,male was slightly higher than female,and the patients in age group of ≥45 reported evidently more compared to younger age group. CONCLUSIONS:By detecting and evaluating alert signals of li-nezolid through OpenFDA platform,we could effectively lay the foundation for further research of pharmacovigilance.

The study of the in vivo-in vitro correlation of the naftopidil sustained-release tablet in dog / 生物医学工程学杂志

We studied the correlation of sustained-release tablet of naftopidil between the in vitro release and the in vivo absorption in the dog. The release rate (X) of naftopidil sustained-release tablet in artificial gastric fluid was determined and the naftopidil concentration in plasma was determined after a single oral dose of 100 mg naftopidil (tablet or sustained-release tablet) in the dog. The absorbed fraction(F) and in vivo absorption rate (A) of the NAF sustained-release tablet in the dog at different time were calculated by W-N method and deconvolution method, respectively. Then the regression equations between F or A and X of the corresponding time point were obtained: F=2. 1533X - 27. 636(r = 0.9927) and A=2.3452X - 25.474(r= 0.9938). W-N method and deconvolution method both indicated that the correlation between the in vitro release and the in vivo absorption in the dog of the NAF sustained-release tablet was good.
