ABSTRACT
OBJECTIVE： To conduct bibliometric analysis of off-label use in domestic and foreign. METHODS： Retrieved from CNKI， Wanfang database， VIP， PubMed， Embase and Web of Science during Jan. 1991 （in foreign） or Jan. 2007 （in domestic） to Dec. 2018， related literatures of off-label use were collected. General information （publication numbers distribution， journals distribution）， article cooperation （core researchers， research content） and keywords of domestic and foreign literatures were analyzed and summarized. RESULTS： A total of 1 647 domestic and 4 418 foreign literatures were retrieved， including 1 570 domestic and 4 238 foreign valid literatures. Publications increased over the past decade， with the largest number of domestic and foreign publication numbers in 2017 （355 in domestic and 465 in foreign）. The most published domestic and foreign journals were China Pharmacy （105 literatures） and European Journal of Clinical Pharmacology （51 literatures）. The core researchers in domestic and foreign were Li Youping and de la Torre JC. The contents of domestic researches included off-label use policy， current situation of off-label use in children， off-label use in ophthalmology， off-label use of Chinese patent medicine， etc. The contents of foreign researches included off-label use in antiviral drugs， off-label use in special population （children， alcoholic dependence patients， etc.）. Off-label use， rational drug use and drug instructions as well as human， off-label use and article were the top 3 keywords in domestic and foreign literatures， respectively. CONCLUSIONS： Off-label use research at home and abroad is increasing year by year. Research teams carry out co-operations actively. Bibliometric methods can help researchers broaden research directions， track research hotspots and select contributing journals.
ABSTRACT
Objective To explore the state of cardiac autonomic nerve function in schizophrenia patients with metabolic syndrome and analyze its influence factors and to reduce the occurrence of sudden cardiac death of the patients. Methods A total of 168 cases of patients according with the ICD-10 schizophrenia diagnostic criteria were divided into group A(78 cases of schizophrenia with metabolic syndrome),group B(90 cases of schizophre-nia without metabolic syndrome)and another 92 normal cases were included as control group(group C). Twenty-four hours dynamic electrocardiogram was conducted respectively and the heart rate variability (HRV) was ana-lyzed. Results Values of LF,HF,SDNN,SDANN,RMSSD and PNN50 in group A and group B were much low-er than those in group C and they were statistically significant(P < 0.05). Values of LF,HF,SDNN,SDANN, RMSSD and PNN50 in group B were much higher than those in group A and they were statistically significant(P<0.05). Excluding the influence of schizophrenia ,logistic regression analysis showed that the influence factors of HRV values were course of the disease(OR = 1.864,95%CI 1.110~3.128),age(OR = 1.170,95%CI 1.018~2.491),types of antipsychotic drugs(OR=2.419,95%CI 0.976~1.835),abdominal obesity(OR=2.425,95%CI 1.347~4.366),blood pressure value(OR=1.263,95%CI 1.575~3.937),blood glucose value(OR=3.376, 95%CI 1.359~2.923)and blood lipid value(OR = 2.178,95%CI 1.492~6.756). Conclusions Schizophrenia patients with metabolic syndrome have obvious cardiac autonomic nerve dysfunction. Excluding the influence of schizophrenia itself,the other possible risk factors include course of the disease,age,types of antipsychotic drugs,abdominal obesity,blood pressure value,blood glucose value and blood lipid value.

ABSTRACT
OBJECTIVE:To evaluate the association between UGT1A1 gene polymorphism and irinotecan-induced 3-4 degree neutropenia,and to provide evidenced-based reference for clinical treatment. METHODS:Retrieved from CJFD,Wanfang data-base,VIP,PubMed,EMBase,Science direct and Cochrane library,related studies about UGT1A1*28 and UGT1A1*6 gene polymorphism and irinotecan-induced 3-4 degree neutropenia were collected. After data extraction and quality evaluation of included studies,Meta-analysis was conducted by using Review Man 5.3 software. RESULTS:A total of 29 studies were included,involv-ing 2408 patients. UGT1A1*28 includ wild genotype TA 6/6(UGT1A1*1/*1)and mutations genotype TA 6/7(UGT1A1*1/*28)、TA 7/7(UGT1A1*28/*28),UGT1A1*6 includ wild genotype GG and mutations genotype GA、AA. Results of Meta-analysis showed:the incidence of 3-4 degree neutropenia in UGT1A1*28 and UGT1A1*6 mutations genotype were significantly higher than wild genotype,with statistical significance [UGT1A1*28:OR=1.92,95%CI(1.52,2.44),P<0.001;UGT1A1*6:OR=2.49, 95%CI(1.46,4.26),P<0.001]. Using medium-dose and high-dose of irinotecan,the incidence of 3-4 degree neutropenia in UGT1A1*28 and UGT1A1*6 mutations genotype were significantly higher than wild genotype,with statistical significance [UGT1A1*28:OR=2.06,95%CI(1.57,2.70),P<0.001);UGT1A1*6:OR=1.92,95%CI(1.35,2.74),P<0.001]. Using low-dose of irinotecan,there was no statistical significance in the incidence of 3-4 degree neutropenia between UGT1A1*28,UGT1A1*6 mutations genotype and wild genotype [UGT1A1*28:OR=1.20,95%CI(0.70,2.08),P=0.51;UGT1A1*6:OR=3.19,95%CI (0.85,11.89),P=0.08]. CONCLUSIONS:Using medium-dose and high-dose of irinotecan,UGT1A1*28 and UGT1A1*6 muta-tions will increase the risk of severe neutropenia in cancer patients. Using low-dose of irinotecan,there is no clear correlation be-tween gene polymorphism and the neutropenia.

ABSTRACT
OBJECTIVE:To develop a HPLC-ECD method for the determination of scutellarin in human plasma.METH-ODS:The plasma sample injection was performed after protein precipitation by methanol.The mobile phase consisted of 0.083mol? L-1 sodium dihydrogen phosphate-methanol-acetonitrile-tetrahydrofuran(60:30:10:0.4),which was added dropwise with H3PO4 in a ratio of 100:106).The column temperature was under room temperature;the detection voltage was 100mV;the protection voltage was 500mV;the flow rate was 1mL? min-1 and the sample size was 20? L.RESULTS:The calib-ration curve was linear in the range of 20.0～ 400.0?g? L-1(r=0.999 9).The methodological recovery was 96.79% ～ 108.50%.Both the intra-day and inter-day RSD were less than 5%.CONCLUSION:This HPLC-ECD method is accurate,sensitive and simple,and suitable for pharmacokinetic study of scutellarin.
ABSTRACT
OBJECTIVE: To evaluate the efficacy and safety of diammonium glycyrrhizinate in the treatment of drug-induced liver injury according to present clinical studies. METHODS: Retrieved from CBM and the CNKI from 1994 to 2009, literatures about the randomized controlled trials that the effective rate of diammonium glycyrrhizinate was compared with that of other hepatoprotective with drug-induced liver injury and drug-induced liver disease as study subjects. RESULTS: 18 RCTs including 1,644 patients with drug-induced liver injury were enrolled. The effective rate of diammonium glycyrrhizinate group was higher than that of control group, statistical significance was noted in two groups (P
ABSTRACT
OBJECTIVE:The bioassay and HPLC methods were established and compared for the determination of levofloxacin(Lev) in human plasma.METHOD:In bioassay,medium Ⅱ and staphylococcus aureus were used.The HPLC method was chromatographed with a mobile phase of methanol-0.02mol/L potassium dihydrogen phosphate solution (3∶7)，the sample was treated by adding 30% trichloroacetic acid to precipitate protein,and detected at 276mm.RESULTS:The average recovery of bioassay was within 95.90%～106.68%,the within-day and day-to-day precisions were below 6%.The average recovery of HPLC was within 97.24%～101.70%,the within day and day-to-day precisions were blow 5%.Lev tablets were given to 6 patients in two ways.Drug concentrations in plasma were determined by bioassay and HPLC assay,respectively,with no significant difference (P＞0.05).CONCLUSION:The bioassay was simple,cheap,time saving,and reliable.The HPLC method wsa rapid,sensitive,accurate.The two methods may be selected to use in actual conditions.
