OBJECTIVE:To probe into the status quo and characteristics of the adverse drug reactions (ADR) occurred in our hospital.METHODS:A total of 560 ADR cases collected in our hospital from 2004 to 2008 were analyzed statistically in respect of patients' age and sex,drug varieties,route of administration and clinical manifestation,etc.RESULTS:Of all the ADR cases reported in our hospital,51.8% were induced by anti-infective drugs vs.10.7% by traditional Chinese medicines;51.8% manifested as lesions of skin and its appendants,but none of them died.CONCLUSION:Clinical importance should be attached to the monitoring of ADR,the indications of the anti-infective drugs and traditional Chinese medicines should be strictly followed in order to decrease the incidence of ADR.

Objective To study the expression levels of N-terminal pro-brain natriuretic peptide (NT-proBNP),serum albumin of Kawasaki' s disease (KD),incomplete Kawasaki' s disease (IKD),and children whose fever were unexplained and to explore the clinical significance of the levels of NT-proBNP and serum albumin in the early diagnosis of IKD.Methods The levels of NT-proBNP of 246 cases of KD (KD group),61 cases of IKD (IKD group) and 301 cases of children with unexplained fever (fever group)were measured by the enzyme-linked fluorescence analysis (ELFA) at the day of admission,meanwhile,the levels of albumin were tested in KD,and IKD children were underwent ECG and echocardiography.Based on the test results,patients were further divided into the group with cardiovascular damage and the group without cardiovascular damage.SPSS 19.0 was used for statistical analysis.The t test was used to compare the parameters between each group,the variance analysis and association analysis were carried out with Pearson's correlation analysis.The ROC curve analysis was done to identify the cardiovascular damage threshold.Results ① The level of plasma NT-proBNP of the KD group,the IKD group was significantly h igher than the fever group [(789.1±4.7) ng/L,(824.8±4.4) ng/L vs (92.5±2.3) ng/L,F=230.736,all P＜0.05];② The level of albumin of the KD group and the IKD group was significantly lower than that of the fever group [(33.9±2.8) g/L,(33.8±3.1) g/L vs (40.8±3.6) g/L,F=355.648,all P＜0.05]; ③ The levels of NT-proBNPs between the cardiovascular damage group and the groups without cardiovascular damage among the KD group,and those of the IKD groups were compared.In the KD group,the NT-proBNPs level of the two subgroups was (2948±3) g/L (n=103) vs (305±3) g/L,n=143; while in the IKD group,the NT-proBNPs of the two subgroups was (1454±4) g/L (n=38) vs (323±4) g/L (n=23).The dif-ferences were statistically significant (t=16.464,4.356,all P＜0.05).④ The plasma NT-proBNP level higher than 933.5 ng/L was identify as the indicator for cardiovascular damage in both KD and IKD children.Its sensi-tivity was 88.1％,and its specificity was 89％.⑤ When the level of NT-proBNP was higher than 250 ng/L,the sensitivity for diagnosis in the KD,the IKD was 80.9％,85.2％ respec-tively,and the specificity was 85.7％.When the level of NT-proBNP was higher than 250 ng/L and that of albumin was lower than 35 g/L,the sensitivity for diagnosis of KD,IKD was 67.5％,70.5％ respectively,the specificity was 99.7％.Conclusion The level of plasma NT-proBNP (＞250 ng/L) accompanied by decreased albumin (＜35 g/L) may be specific markers for early diagnosis of IKD.In addition,the level of NT-proBNP ≥933.5 ng/L can be used as a diagnostic threshold,which has good sensitivity and specificity for identifica-tion of cardiovascular damage in the KD and IKD in children.

Objective To observe the levels of N-terminal pro-brain natriuretic peptide (NT-proBNP),high density lipoprotein cholesterol (HDL-C) in predicting cardiovascular damage in Kawasaki disease (KD).Methods Enzyme-linked fluorescence analysis (ELFA) technique was used to measure serum NT-proBNP levels in 406 KD patients [including 104 cases of incomplete Kawasaki disease (IKD)] at the acute phase,the convalescent stage,at the same time,the blood HDL-C,Albumin,globulin,alanine aminotransferase (ALT),C-reactive protein (CRP),red blood cell sedimentation rate (ESR),blood white cell count (WBC),hemoglobin (Hb),blood platelet count (PLT) level were tested.According to the results of echocardiography,electrocardiogram,myocardial enzymes in KD,patients were divided into two groups:two hundred and twenty-two with cardiovascular damage and 184 without cardiovascular damage group.The age,gender,fever,the first application of the intravenous gamma globulin,laboratory markers of clinical features observed above the detection levels were compared,and these parameters for each group were compared using t test or analysis of variance,the single factor which was statistically significant were received operating characteristic curve (ROC) analysis.Then the cardiovascular damage group was divided into echocardiography abnormal group and echocardiography normal group,and t test was adopted to compare the clinical parameters of the two groups.Results ① The age,lip and oral changes,the first application of intravenous gamma globulin,blood NT-proBNP,HDL-C,albumn and ALT was significantly different between the cardiovascular damage group and non cardiovascular damage group (t/x22=4.989,4.721,6.212,18.834,12.788,4.851,4.541,All P＜0.05).② When the blood NT-pro-BNP was higher than 786.5 ng/L,its sensitivity and specificity for differentiating KD with cardiovascular damage was 86.5％ and 84.8％,respectively.When the blood HDL-C was lower than 0.655 mmol/L,its sensitivity and specificity for differentiating KD with cardiovascular damage was 80.4％ and 69.4％ respectively.When the blood NT-proBNP was higher than 786.5 ng/L in addition to HDL-C lower than 0.655 mmol/L,the specificity for differentiating KD with cardiovascular damage was 91.8％.③ For the 222 cases with cardiovascular dam-age,their blood NT-proBNP,HDL-C levels were statistically significantly different between the echocardiogra-phy abnormal group and echocardiography normal group (t=3.354,4.084,All P＜0.05).④ The serum NT-proBNP,ALT levels of the 406 acute and convalescent KD patients were significantly higher than the recovery phase.The blood HDL-C,albumin level of acute patients were significantly lower than those at the recovery phase,the difference was statistically significant (t=22.335,4.951,20.334,15.073,All P＜0.05).⑤ One hundred and four children with IKD were divided into patients with cardiovascular damage (74 cases) and without cardiovascu-lar damage (30 cases),the age,lip and oral changes,the first application of intravenous gamma globulin,blood NT-proBNP,HDL-C,albumin and ALT were significantly differentbetween these two groups (t=3.083,2.157,6.423,6.409,3.649,8.658,All P＜0.05).Conclusion Blood NT-proBNP and HDL-C are good pre-dictive parameters in children with cardiovascular damage of KD,IKD.

Objective: To investigate the dynamic electrocardiogram (ECG) changes of head-up tilt test in patients with suspected vasovagal syncope. Methods: A total of 502 outpatients of our hospital with suspicious vasovagal syncope from 2015-08 to 2016-12 were enrolled. All patients received head-up tilt test with synchronization of 12 lead ECG. Based on head-up tilt test result, the patients were divided into 2 groups: Positive group,n=244 and Negative group,n=258. The P wave duration, corrective QT (QTc) duration and P wave axis in ECG were compared between 2 groups. Results: Compared with Negative group, Positive group had the longer P wave duration (95.65±38.50) ms vs (88.61±17.09) ms,P<0.05; P wave axis was right shifted before syncope (69.87±18.18)° vs (66.82±16.51)° , while left shifted during syncope (62.87±25.39)° vs (68.47±15.30)° and after syncope (56.87±22.45)° vs (68.49±16.35)°, allP<0.05; the shorter QTc duration before syncope (418.69±92.35) ms vs (435.76±59.29) ms,P<0.05. Conclusion: The patients with vasovagal syncope had some speciifc ECG features during head-up tilt test including P wave duration, P wave axis and QTc duration, those may play certain forewarning function for vasovagal syncope onset.

【Objective】 To develop and implement a precise and efficient telephone recruitment strategy for apheresis platelet donors based on the information management of blood collection and supply process. 【Methods】 A telephone recruitment strategy based on the whole process information management of apheresis platelet donors (hereinafter referred to as telephone recruitment) was formulated From January 1, 2019, apheresis platelet donors in Hangzhou, registered in the intelligent blood donor recruitment system(hereinafter referred to as the recruitment system), were recruited by telephone calls or (and) SMS reminders to inform re-donation interval, key points of recruitment consultation, blood donation appointment time and other precautions. Response rate, pass rate and blood donation rate of donors before(in 2018) and after( in 2019) the implementation of telephone recruitment, as well as the above three rates during the COVID-19 epidemic in 2020 in Hangzhou were collected and analyzed by χ² test. 【Results】 The response rate, pass rate, and blood donation rate of apheresis platelet donors in Hangzhou before /after the implementation of telephone recruitment and during the COVID-19 epidemic were 28.52%(3 901/13 678)vs 30.52%(4 429/14 511)vs 39.36%(4 064/10 326), 73.80%(2 879/3 901)vs 77.83%(3 447/4 429)vs 78.20%(3 178/4 064)and 6.77%(2 879/42 553)vs 7.77%(3 447/44 366)vs 8.13%(3 178/39 077, respectively(P<0.05). In 2020, 85.94%(3 178/3 698) of apheresis donors were recruited by telephone(P<0.05). The proportion of apheresis donations successfully recruited by telephone in 2018 and 2019 accounted for 11.74% (2 879/24 519) and 12.48% (3 447/27 628), respectively(P<0.05), contributing 10.59% (4 030 U/38 040 U) and 11.38% (4 875 U/42 853 U) of units(P<0.05) that issued to the clinical. Due to the COVID-19 epidemic, the number of blood donors recruited by telephone and its proportion in 2020 decreased significantly as compared with those before the implementation of telephone recruitment (2019). 【Conclusion】 The telephone recruitment strategy based on the whole-process information management (system) of blood collection and supply can effectively improve the targeted recruitment of apheresis platelet donors and enhance its proportion of apheresis collection that issued to the clinical.
