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 explore the interaction between a serotonin transporter gene promoter region polymorphism(5-HTTPR) and stress in predicting anxiety symptoms.Methods Through random cluster sampling,a total of 252 healthy adolescents participated in this study.During the initial assessment,all participants completed the Adolescent Life Events Questionnaire (ALEQ) and Multidimensional Anxiety Scale for Children (MASC) to assess their levels of stress and anxiety and were genotyped for the 5-HTTLPR polymorphism.Participants subsequently completed MASC and ALEQ once every three months during the subsequent 24 months.A multilevel model was used to investigate the interaction between 5-HTTLPR and stress that predict anxiety symptoms.Results The results indicated no major effect of 5-HTTLPR in males (β=0.80,P＞0.05)or females(β=-0.21,P＞0.05).There were major effects of stress in males(β=0.30,P＜0.01) and females (β=0.33,P＜0.01)and a significant interaction between 5-HTTLPR and stress.Females with at least one 5-HTTLPR S allele(β=0.11,P＜ 0.01)and males with at least one 5-HTTLPR L allele(β=-0.10,P＜0.01)exhibited more anxiety symptoms under stressful situations.Conclusion The interaction between 5-HTTLPR and stress can predict anxiety symptoms in adolescents.There are gender differences on the 5-HTTLPR × stress interaction.

Objective To compare the clinical effects of intravascular ultrasound (IVUS) and blood flow reserve fraction (FFR) in guiding the treatment of critical disease of coronary artery.Methods Forty nine patients with coronary artery disease who underwent coronary angiography were divided into IVUS group (n=43) and FFR group (n=51).In IVUS group,such as MLA ＜4 mm2 or coronary artery stenosis was insufficient,but IVUS showed unstable plaque,and we went the PCI treatment;in the FFR group,FFR＜0.75 was regarded as coronary stenting sign.The patients were followed up for 6 months.The incidence of cardiovascular adverse events was compared between the two groups.Results (1)There was no significant difference in general information and coronary angiography between the two groups (P＞ 0.05).(2)The proportion of interventional therapy in IVUS group was higher than that in FFR group (P＜0.01).(3)The incidence of adverse events between the two groups was not statistically significant (P＞0.05).Conclusion IVUS and FFR examination can be used to guide the interventional treatment of critical disease of coronary artery.However,the accuracy of IVUS can not replace the status of blood flow reserve.

Objective To evaluate the application effect of telemedicine robot on the postoperative follow-up of liver transplantation recipients from donation after cardiac death (DCD). Methods A total of 100 recipients undergoing liver transplantation from DCD in the First Affiliated Hospital of Xi 'an Jiaotong University from January 2014 to December 2017 were recruited in this investigation. According to differnt follow-up patterns, all recipients were divided into the research group (n=50, follow-up by telemedicine robot) and control group (n=50, follow-up by traditional telephone). The compliance (medication compliance, self-monitoring, life compliance and follow-up compliance), follow-up time and follow-up satisfaction at postoperative 3 months of all DCD liver transplantation recipients were analyzed and statistically compared between research group and control group. Results The scores of medication compliance, self-monitoring, life compliance, follow-up compliance and the total score of compliance in the research group were significantly higher than those in the control group (all P < 0.05). The each follow-up time of liver transplantation recipients in the research group was (9±4) min, significantly shorter than (13±4) min in the control group (t=-4.452, P < 0.001). The score of satisfaction during postoperative follow-up in the research group was 19.8±2.6, significantly higher than 16.2±3.1 in the control group (t=6.234, P < 0.001). Conclusions The application effect of telemedicine robot on the postoperative follow-up of liver transplantation recipients from DCD is satisfactory, deserves widespread application in clinical practice. It is expected to become an indispensable part of the postoperative follow-up of liver transplantation recipients from DCD.

Uncovering the risk factors of pulmonary hypertension and its mechanisms is crucial for the prevention and treatment of the disease.In the current study,we showed that experimental periodontitis,which was established by ligation of molars followed by orally smearing subgingival plaques from patients with periodontitis,exacerbated hypoxia-induced pulmonary hypertension in mice.Mechanistically,periodontitis dysregulated the pulmonary microbiota by promoting ectopic colonization and enrichment of oral bacteria in the lungs,contributing to pulmonary infiltration of interferon gamma positive(IFNγ+)T cells and aggravating the progression of pulmonary hypertension.In addition,we identified Prevotella zoogleoformans as the critical periodontitis-associated bacterium driving the exacerbation of pulmonary hypertension by periodontitis,and the exacerbation was potently ameliorated by both cervical lymph node excision and IFNγ neutralizing antibodies.Our study suggests a proof of concept that the combined prevention and treatment of periodontitis and pulmonary hypertension are necessary.

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.

Objective:To analyze the epidemic characteristics of human brucellosis in Xianyang City, Shaanxi Province, to grasp the epidemic trend and provide scientific basis for further prevention and control of human brucellosis.Methods:Descriptive epidemiological methods were used to statistically analyze the incidence data and epidemic data of human brucellosis in Xianyang City, Shaanxi Province from 2011 to 2020 in the "Infectious Disease Surveillance System of China Disease Control and Prevention Information System".Results:A total of 864 human brucellosis cases had been reported in Xianyang City from 2011 to 2020, and there was no dead case. The annual incidence began to increase rapidly from 2014, the highest annual incidence in 2019 was 5.79/10 5. There were statistical differences between the incidence of different years (χ 2 = 900.40, P < 0.001). Human brucellosis cases in Xianyang City were mainly concentrated in dairy goat breeding counties, with a total of 571 cases reported, accounting for 66.09%. Cases were reported in all months of the year, and the peak incidence of human brucellosis was from April to August, accounting for 64.35% (556/864). The age of cases was mainly concentrated in the 40 - 69 years old group, accounting for 68.29% (590/864); the ratio of male to female was 2.40 ∶ 1.00 (610 ∶ 254). The occupation was mainly farmers, accounting for 83.45% (721/864). There had been an increase in the proportion of scattered children, students and preschool children. The total serological positive rate was 3.14% (283/9 009) in Xianyang City, and pathogenic culture showed variant strains. The median of interval between onset time and diagnosis time was 8 days. Conclusion:The prevalence of human brucellosis in Xianyang City, Shaanxi Province shows an overall upward trend, which needs to be paid more attention to and control efforts should be strengthened.

Objective To explore the key nursing cooperation points in single-port laparoscopic cholecystectomy based on magnetic anchor technique.Methods The general information of 24 pa-tients with transumbilical single-port laparoscopic cholecystectomy based on magnetic anchor tech-nique was analyzed.Combined with the surgical procedure,the key nursing cooperation points of this innovative surgery were analyzed from the perspective of operating room nurses.Results By learning the principles of magnetic anchor technique before surgery,understanding the usage and precautions of the magnetic anchor device,accurately passing the magnetic anchor device during surgery,and a-voiding mutual interference between the magnetic anchor device and conventional surgical instruments,the operating room nurses successfully assisted the surgeons in completing 24 cases of transumbilical single-port laparoscopic cholecystectomy based on magnetic anchor technique.Conclusion Real-time understanding of the surgeon's operation progress during surgery,accurate delivery of instruments,and avoidance of interference between the magnetic anchor device and conventional surgical instru-ments are important factors in the nursing cooperation of this surgical procedure.

Objective To investigate the feasibility of the optimally designed"I"shaped structure mag-net based on the principle of magnetic compression technique for the preparation of rectovaginal fistula animal model.Methods Using 10 New Zealand female rabbits as the model animals,two self-designed magnets were inserted through the vagina and anus respectively after anesthesia,and the two magnets were adjusted to the appropriate position and made them attraction each other to form a magnet-rectovaginal partition-magnet structure.When the compression tissue between the magnets became ischemic necrosis and fell off,the two magnets formed the"1"shape structure and were located in the stoma of rectovaginal fistula to prevent the stoma from becoming smaller or even closing itself.The operation time and rectovaginal fistula formation time were recorded.The experimental rabbits were killed in postoperative 2 weeks,and the rectovaginal fistula specimens were obtained.The formation of fistula orifice was observed and the size of fistula orifice was meas-ured.Results The animal model of rectovaginal fistula was successfully prepared in all 10 experimental rab-bits.The procedure of intraoperative magnet placement was smooth and the operation time was(1.55±0.65)min.The experimental animals were generally in good condition after surgery,and the fistula orifice was formed on postoperative(4.80±0.75)d.After taking the gross specimen of rectovaginal septum in postopera-tive 2 weeks,the magnet was removed.The fistula orifice of rectovaginal fistula was visible with the diameter of(5.86±0.38)mm.Conclusion The"I"shaped structure magnet designed based on the principle of mag-netic compression technique could be used in the preparation of the rectovaginal fistula animal model.Its oper-ation is simple with high success rate of model preparation and good uniformity in fistula orifice.
