Objective To develop a multivariate modeling and prediction approach using the data of influenza incidence, meteorological factors and PM2.5 variables in Hefei City, and to provide new insights into multivariate modeling and prediction methods. Methods PM2.5 data were transformed into fractal dimension data and, along with meteorological data, were incorporated into a ConvLSTM model. The performance of this model was compared with traditional ARIMAX and multivariate LSTM models. Results The ARIMAX model's testing set Mean Absolute Error (MAE) was 95.75, Root Mean Square Error (RMSE) was 176.72, and Index of Agreement (IA) was 0.396642. The multivariate LSTM model's testing set MAE was 22.18, RMSE was 43.06, and IA was 0.974611. For the fractal dimension-based ConvLSTM model, the testing set MAE was 17.37, RMSE was 32.25, and IA was 0.988149. Conclusion The fractal dimension effectively captures the complexity and self-similarity of PM2.5 concentration, providing the model with richer feature information. The fractal dimension-based ConvLSTM model significantly outperforms the traditional ARIMAX model and the multivariate LSTM model in prediction accuracy and can be used for predicting the number of influenza cases.

The intervention and prevention of perioperative hypothermia is not only reflected in the technical level, but also reveals the important role of humanistic care in the whole intervention work. If perioperative patients have hypothermia, it is likely to cause a series of complications such as postoperative shivering, which seriously threatens the life safety of patients. Prevention and intervention was based on a comprehensive understanding of the causes and hazards of hypothermia, especially the impact on the lives of the elderly. Effective supervision was implemented in the whole process of operation, such as dynamic monitoring of vital signs including body temperature, followed by room temperature regulation, body temperature protection and preoperative and postoperative psychological nursing. At this time, the sense of responsibility, good humanistic care of medical staff are of positive significance to effectively prevent and reduce the probability of perioperative hypothermia and accelerate the postoperative rehabilitation of patients.

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 (FIS) 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 (FST) 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.
