OBJECTIVE To identify and analyze adverse drug event （ADE） signals associated with tirzepatide based on the FDA Adverse Event Reporting System （FAERS） database， providing a reference for clinical medication safety. METHODS ADE reports from January 1， 2022， to June 30， 2024， with tirzepatide as the primary suspected drug， were extracted from the FAERS database. Medical Dictionary for Regulatory Activities was used to systematically categorize the selected system organ class （SOC） and preferred term of ADE. Signal mining and analysis were performed using the reporting odds ratio method and the proportional reporting ratio method. RESULTS A total of 39 229 ADE reports related to tirzepatide were obtained， including 3 934 severe ADE reports （10.03%）. The majority of severe ADE reports were related to hospitalization or prolonged hospitalization （3.82%）， involving 131 positive ADE signals. Among the reports with documented patient gender and age， 26 195 were female （66.77%）， 7 869 were male （20.06%）， and the majority of patients were aged 18-64 years （54.26%）. The top three most frequently reported ADE were injection site pain， nausea， and injection site hemorrhage. Strong ADE signals not mentioned in the tirzepatide instruction included injection site coldness， starvation ketoacidosis， injection site hemorrhage， hunger， elevated adrenaline， injection site skin cracking， binge eating， skin laxity， intestinal sepsis， lack of satiety， and dysesthesia. Subgroup analysis for patient’s gender and age showed differences in the proportion of ADE reports across different SOC. Male patients or those aged≥65 years had a higher risk of gastrointestinal system disorders compared to female patients or those aged ＜65 years. CONCLUSIONS In clinical use of tirzepatide， in addition to monitoring ADE listed in the instruction， attention should also be paid to ADE not mentioned in the instruction， such as injection site coldness， starvation ketoacidosis， injection site hemorrhage， elevated adrenaline， and intestinal sepsis， to ensure patient safety.

Objective To analyze correlation of endolymphatic hydrops (EH) in the inner ear with age in Meniere’s disease (MD) patients. Methods A retrospective analysis were underwent in 101 definite unilateral MD patients. They were divided into young-age (＜18 years old) group, middle-age (18-45 years old) group and elder-age (＞45 years old) group. All patients underwent inner ear three-dimensional inversion-recovery with real reconstruction (3D-real IR) imaging 4 hours after intravenous gadolinium injection. EH rates among different groups were compared. Results The positive rates of EH in the young-age group, middle-age group and elder-age group were 68.2% (15/22), 54.5% (18/33) and 56.5% (26/46), respectively (P＝0.567). There was no difference in the positive rates of EH in vestibule and cochlea among three groups. There was no difference in the rates of mild and significant EH in vestibule and cochlea among three groups. Conclusions Age might not be related to the occurrence of EH in the inner ear in MD patients.

OBJECTIVE To investigate the current situation of pharmaceutical management in compact medical consortium of Guangdong province， and to provide decision-making basis for promoting the high-quality construction and sustainable development of the provincial medical consortium. METHODS A self-designed questionnaire was used to select 50 compact medical consortiums in Guangdong province. The survey was answered by the heads of the pharmacy department of the general hospitals. The survey covered the basic scale of the consortium， the appointment of chief pharmacists， the implementation of pharmaceutical management and pharmaceutical care homogenization within the consortium， the difficulties in promoting the homogenization， and the expected provincial support. Descriptive statistical analysis was performed on the survey results. RESULTS A total of 50 questionnaires were collected， and the effective recovery rate was 100%. There were 16 chief pharmacists （32.00%） in charge of the pharmacy department of the general hospital in the medical consortium. Thirty-seven medical consortiums （74.00%） had established a drug supply support system within the consortium， 35 medical consortiums （70.00%） had carried out pharmaceutical management and coordination work within the medical consortium， 23 medical consortiums （46.00%） had established a clinical medication guidance system， 25 medical consortiums chenwenying2016@163.com （50.00%） had established a bidirectional communication mechanism， and only 8 medical consortiums （16.00%） had developed new models of pharmaceutical care. At present， the difficulties in promoting the homogenization of pharmaceutical management and pharmaceutical care within the medical consortium were mainly found in three aspects： the wide gap in management level of each member unit， the lack and uneven level of pharmaceutical personnel， and insufficient policy support and implementation. Most medical consortiums hoped that relevant departments could promote the homogenization of pharmaceutical work by holding special training courses or special supervision. CONCLUSIONS At present， the compact medical consortium in Guangdong province has achieved initial results in the implementation of the chief pharmacist system， the homogenization of pharmaceutical management and pharmaceutical care. However， it is still necessary to improve the coverage of chief pharmacist appointments in the medical consortium， implement the homogenization of pharmaceutical management， and accelerate the homogenization process of pharmaceutical care.

Objective:To establish the standard of nursing quality in bone oncology department, and provide the basis for scientific evaluation of nursing quality in bone oncology department.Methods:On the theoretical basis of Donabedian′s three-dimensional quality model of "structure-process-outcome", and through literature review and semi-structured interview method, the "evaluation index of nursing quality in bone oncology department" was preliminatively formulated from November 2022 to June 2023. The Delphi method was used to select 31 experts from 31 third-level A hospitals and nursing colleges in 27 provinces or municipalities across the country for two rounds of correspondence consultation. The criteria were screened and modified to determine the evaluation criteria of nursing quality in bone tumor specialty.Results:The questionnaire recovery rate of 2 rounds of expert consultation was 100.00%, the authority coefficient of 2 rounds of expert consultation was 0.93, and the coefficient of variation of 1, 2 and 3-grade standards were all less than or equal to 0.25. The Kendall′s coefficient of concordance of the primary standards of the two rounds of expert consultation were both 0.088, in the secondary standards were 0.103 and 0.140, in the tertiary standards were 0.119 and 0.110. Through 2 rounds of expert letter consultation, the evaluation criteria for the quality of care in bone tumor specialties were divided into three levels, including 3 primary standards (structural quality criteria, process quality criteria and outcome quality criteria), 21 secondary standards and 80 tertiary standards.Conclusions:The construction process of nursing quality standard in bone oncology department is scientific and reliable, reflecting specialty characteristics, and can provide scientific basis for the evaluation of nursing quality in bone oncology department and standardize nursing behavior.

ObjectiveTo genotype Oncomelania hupensis， based on microsatellites， in different snail-bearing environments in Jiaxing City， Zhejiang Province， for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village （YB） and Sanxing Village （SX） in Pinghu City， and Yunhe Farm （YH） in Xiuzhou District， all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed， and the mean number of alleles （Na） was 7.889， 5.667， and 3.778 for YB， SX， and YH respectively； the number of effective alleles （NeA） was 4.807， 3.329， and 2.294， respectively； and the coefficients of inbreeding （F_IS） were 0.400， 0.377， and 0.493， respectively. Under the Infinite Allele Model （IAM）， the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes （Ne） were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals， accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations （F_ST） was 0.286， indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent， and the three populations were divided into two lineages， YB and SX were one lineage， and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient， population divergence history indicated that YH might have diverged from SX first， and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low， and the snail populations are unstable， with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.
