OBJECTIVE:To provide reference for rational drug use in respiratory department. METHODS:ADR/ADE report-ed by respiratory department of a class three grade A hospital during Jan. 2011 to Dec. 2015 from national ADR monitoring system were collected. 2011-2015 ADR/ADE database of respiratory department in a hospital was established and analyzed statistically. RE-SULTS:202 records were gotten,among which 89 cases were male(44.06%)and 113 cases were female(55.94%);the patients’ age approximated normal distribution,the incidence of ADR/ADE was the highest in 61-80 age group (55.94%);the occurrence time of ADR/ADE was mostly lower than 1 h (47.21%);the main route of administration was intravenous drip (71.29%);22 kinds of drugs were involved,and antibiotics took up the lead(43.11%);84 patients(41.58%)used 2 and more kinds of drugs before the occarrence of ADR/ADE;organs/systems involved in ADR/ADE were skin and its appendants (32.86%) and digestive system(26.19%). Most of the ADR/ADE could be cured or recovered after related treatment. CONCLUSIONS:The occurrence of ADR/ADE in respiratory department is related to various factors,of which advanced age,intravenous administration and antibiotics use are important ones. Great importance should be attached to rational clinical drug use as well as ADR/ADE monitoring and re-porting. Clinical also should pay attention to the safety of drug use in elderly patients.

Objective:To analyze the incidence of brucellosis and the genotypes of Brucella isolates or nucleic acids in Shaanxi Province, to get the epidemiological and molecular genetic characteristics, and to provide scientific basis for precise prevention and control of human brucellosis. Methods:Log into the Chinese Disease Control and Prevention Information System, collect the incidence data of human brucellosis of Shaanxi Province in 2020, and analyze the epidemiological characteristics. Bacteriology and PCR methods were used to identify the isolates or nucleic acids, and multiple locus variable-number tandem repeat analysis (MLVA) was used for molecular typing. BioNumerics (Version 7.6) software was used to analyze the results of MLVA.Results:In 2020, 1 086 cases of human brucellosis were reported in Shaanxi Province, the incidence rate was 2.80/100 000, involving 86 counties (districts), the epidemic peak was from March to September (865 cases), male-to-female ratio was 2.68 ∶ 1.00 (791 ∶ 295), 79.74% (866 cases) in the age group of 30 to 69 years old, and 83.43% (906 cases) of the cases were farmers. Biotype identification of 36 isolates showed that 4 isolates were mutant Brucella melitensis, 3 isolates were Brucella melitensis 1 and 29 isolates were Brucella melitensis 3. The 36 isolates and 7 nucleic acids were identified as Brucella by BCSP31-PCR and Brucella melitensis by AMOS-PCR. MLVA-16 genotyping, panel1 showed two genotypes: type 42 (1-5-3-13-2-2-3-2) and type 63 (1-5-3-13-2-3-3-2), panel2A showed 4-41-8 and panel2B showed high variability. Thirty-six isolates and 7 nucleic acids were divided into 33 genotypes, of which 27 genotypes were single isolates and 6 genotypes were shared. Conclusions:The situation of human brucellosis prevention and control in Shaanxi Province is grim. MLVA-16 is a mature genotyping method, which determines the existence of multiple genotypes of Brucella isolates or nucleic acids in Shaanxi Province, which can provide scientific information for precise prevention and control of human brucellosis, outbreak analysis and epidemiological traceability.

Objective:To understand the changes of brucellosis prevention and control knowledge awareness among breeders in Chunhua County, Xianyang City, Shaanxi Province before and after the publicity intervention.Methods:A multi-stage cluster sampling method was adopted to select 10 townships with more reported cases of human brucellosis in Chunhua County from January 2019 to June 2020, and each township was given priority to select the administrative village with the largest number of reported cases for investigation. At least 20 breeders aged 20 years old and over in each administrative village were selected, and if the number was insufficient, supplementary surveys would be conducted in other administrative villages with the larger number of breeders in the township. Questionnaire survey was conducted on all subjects, including general demographic characteristics, brucellosis prevention and control knowledge and related protective behaviors. After the baseline investigation, 6 months of brucellosis prevention and control knowledge publicity was carried out in the administrative villages included in the investigation, and the awareness rate of brucellosis prevention and control knowledge before and after the publicity intervention was compared to evaluate the effect of publicity intervention.Results:After the publicity intervention, a total of 240 breeders were investigated, and 176 people were aware of brucellosis prevention and control knowledge, with an overall awareness rate of 73.33% (176/240), which was significantly higher than that before the publicity intervention (57.50%, 115/200), and the difference was statistically significant (χ 2 = 12.21, P = 0.005). After the publicity intervention, the awareness rates of breeders on "can cattle and sheep transmit diseases to humans" and "do you know that cattle and sheep can only be purchased after passing the quarantine inspection" were relatively high, they were 95.83% (230/240) and 95.00% (228/240), respectively, and the differences were statistically significant (χ 2 = 50.04, 112.64, P < 0.001) compared with that before the publicity intervention [71.50% (143/200) and 51.00% (102/200)]. The awareness rate of breeders on "how brucellosis is transmitted from livestock to humans" was the lowest, it was 53.33% (128/240), which was not significantly different (χ 2 = 0.82, P = 0.370) from that before the publicity intervention (49.00%, 98/200). Conclusions:After the publicity intervention, the overall awareness rate of brucellosis prevention and control knowledge of breeders in Chunhua County has improved, but the awareness rate of some individual issues is still low. It is suggested to strengthen the pertinence of publicity and education.

And 13 public health emergencies were handled in a timely and effective manner, including incident reporting, epidemiological investigation, high-risk population screening, pathogen cultivation, animal epidemic disposal, disinfection, publicity and education, etc.Conclusion:The brucellosis epidemic is active in the old epidemic areas in northern Shaanxi and the new epidemic areas in Guanzhong area, Shaanxi Province, and targeted prevention and control measures should be formulated according to the epidemiological characteristics of the epidemic to ensure accurate prevention and control of human brucellosis.

Objective:To construct a follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019), and provide a reference basis for the next revision and improvement of the standard.Methods:The evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) was preliminarily established by consulting relevant references and materials. The experts in the field of diagnosis, treatment, prevention and control of brucellosis were selected, and two rounds of expert consultation were carried out in the form of questionnaires using the Delphi method. The necessity and availability of evaluation indicators were scored, and suggestions for modifying and adding indicators were put forward. Based on this, a standard follow-up evaluation index system was established. At the same time, a judgment matrix was constructed combined with the Saaty scale, and the analytic hierarchy process was used to calculate the weight of each index in the system.Results:After 2 rounds of expert ( n = 10) consultation, a standard follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) was constructed with 3 first-level indexes, 8 second-level indexes and 21 third-level indexes. The positive coefficients of experts in 2 rounds of questionnaires were both 100%; the coefficient of authority of experts was 0.82; the Kendall's coefficients of concordance of first-level, second-level and third-level indexes were 0.722, 0.260, and 0.181, respectively, with P < 0.05. Among the first-level indexes, the weight of standard quality evaluation was the highest (0.364), and the weight of standard implementation status was the lowest (0.278); among the second-level indexes, the combined weight of social benefits was the highest (0.186), and the combined weight of advanced nature was the lowest (0.043); among the third-level indexes, the combined weight of timely diagnosis rate was the highest (0.096), and the combined weight of consistency with technical data was the lowest (0.009). Conclusions:The constructed follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) is scientific and reliable, which evaluated qualitatively and quantitatively, reduces the defects of a single evaluation, and provides a basis for subsequent revision and improvement of the standard.

Objective:To analyze the epidemiological characteristics and related indicators of plague in Yulin City, Shaanxi Province, and to evaluate the risk of plague epidemic in the future and formulate scientific and reasonable prevention and control measures.Methods:The plague surveillance data of national (Dingbian County) and provincial (Yuyang District, Jingbian County, Hengshan District, Shenmu City, Fugu County) plague monitoring sites in Yulin City from 2011 to 2021 were collected through the China Disease Prevention and Control Information System Pestis Prevention and Control Management Information System, and the plague epidemic situation among humans and animals, the main host animals and their flea infection were analyzed by descriptive epidemiological methods. The expert consultation method and plague risk assessment tool V1.0 were used to assess the epidemic risk of the plague in Yulin City.Results:There was no human and animal plague epidemic in Yulin City from 2011 to 2021. In national monitoring site, the density of main host animal was 5.79/hm 2, ranging from 3.02/hm 2 to 9.08/hm 2,the dominant species was Mongolian gerbil, accounting for 98.21% (3 402/3 464); the capture rate of wild nocturnal rodents was 1.27% (350/27 600), ranging from 0.21% to 3.83%, the dominant species was Cricetulus barabensis, accounting for 44.86% (157/350); the flea infection rate of the rodent body was 16.91% (768/4 541), with a flea index of 0.40, the dominant flea species was the Nosopsyllus laeviceps kuzenkov, accounting for 66.54% (1 203/1 808). In provincial monitoring site, the density of main host animals was 0.49/hm 2, ranging from 0.31/hm 2 to 0.67/hm 2, the dominant species was Alashan ground squirrel, accounting for 63.61% (194/305); the capture rate of nocturnal rodents in the wild was 1.76% (560/31 795), ranging from 0.89% to 3.93%, the dominant species was Roborovski dwarf hamster, accounting for 26.61% (149/560); the capture rate of domestic rats was 2.37% (397/16 750), ranging from 1.48% to 3.10%, the rodents included Rattus norvegicus (47.36%, 188/397) and house mouse (52.64%, 209/397); the flea infection rate of the rat body was 13.26% (182/1 373), with a flea index of 0.40; the dominant flea species was Ophthalmopsylla jettmari, accounting for 45.23% (251/555). The 5 281 pathogenic culture samples and 2 110 serological test samples were all negative. The Pearson correlation analysis results showed that there was no correlation between rodent density and flea infection rate or flea index at national and provincial monitoring sites ( r = - 0.26, - 0.48, 0.09, 0.12, P > 0.05), while flea infection rate and flea index were positively correlated ( r = 0.67, 0.81, P < 0.05). In 2022, Yulin City, Shaanxi Province was not ruled out the possibility of human plague epidemic, and the risk of plague epidemic among animals was high. Conclusions:From 2011 to 2021, the density of the main host animals at the national and provincial monitoring sites in Yulin City has remained at a low level, and the flea index has increased. There is a risk of plague epidemic in Yulin City, so the monitoring work should be further strengthened, and emergency supplies and capacity reserves should be well prepared.
