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.

Objective To examine the effect of ground cage use on Oncomelania hupensis spread, so as to provide insights into precision snail control. Methods Twenty ground cages that were frequently used to capture rice field eels were purchased, including 11 packaging tape-made cages, 7 plastic cages and 2 nylon rope-made cages. The eel-capturing activity was mimicked, and 20 ground cages were assigned in settings with relatively high (1.00 snail/0.1 m2 and higher) and low snail densities (< 1.00 snail/0.1 m2) in Xindai Township, Pinghu City, Zhejiang Province during the period from 15 : 00 to 8 : 00 of the following day on April 13, 26 and 28. The numbers of snails carried by different types of ground cages were compared in settings with different types of snail densities using the rank-sum test. Results A total of 11 cage-times were assigned in settings with a high snail density, and a total of 77 snails were captured, with a mean number of 7 snails in each cage-time and 2.15 snails in 0.1 m2 ground cage. The mean numbers of snails carried by packaging tape-made and plastic cages were 2.47 snails/0.1 m2 cage and 0.37 snails/0.1 m2 cage, respectively. A total of 24 cage-times were assigned in settings with a low snail density, and a total of 8 snails were captured, with a mean number of 0.33 snails in each cage-time and 0.09 snails in 0.1 m2 ground cage. The mean numbers of snails carried by packaging tape-made cages were 0.12 snails/0.1 m2 cage; however, no snails were carried by plastic or nylon rope-made cages. The number of snails carried by ground cages was higher in settings with a high snail density than in settings with a low snail density (Z = −4.019, P < 0.01), and the number of snails carried by packaging tape-made cages was higher in settings with a high snail density than in settings with a low snail density (Z = −4.086, P < 0.01). No significant differences were found in the numbers of snails carried by different types of ground cages. Conclusion The use of ground cage in snail habitats is a contributor to snail spread.

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.

Objective:
To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics.
Methods:
According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated.
Results:
The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases.
Conclusion
This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.

Abstract
On March 12, 2022, a case with Plasmodium vivax malaria was reported in the First Hospital of Jiaxing City. The case sought healthcare services due to persist, sharp distending pain of the brain and fever on February 25, 2022, and the symptoms showed no improvements following symptomatic treatment. Microscopy identified malaria parasites on March 12, and the case was definitively diagnosed as P. vivax malaria on March 13. The case was discharged from hospital on March 16 and relapsed on June 15. The case was a veteran from the China-Myanmar border, where malaria is highly prevalent, and had no history of travel after returning to Jiaxing City on October 2021. Based on epidemiological history and laboratory tests, the case was diagnosed as a cross-border mosquito-borne imported case of P. vivax malaria. The case was given treatment with mosquito vector isolation, and the case's family members, neighbors and colleagues were all tested negative for malaria parasites. There was no Anopheles sinensis detected in the case' residence; however, Anopheles was detected in the neighboring areas, indicating a risk of re-establishment. Returners from high-risk regions including borders and labor exporters are recommended to be included in malaria surveillance, and the sensitivity of malaria surveillance requires to be maintained and the diagnostic and treatment capability of malaria requires to be improved in medical institutions.

Objective:To establish a patient-derived xenograft (PDX) humanized mouse model for hepatoblastoma in children. In addition, compare the biological consistency between successfully modeled PDX tumors and primary tumors in children while comparing and analyzing the influence of PDX model modeling success as a key factor.Methods:A PDX tumor model was constructed from fresh tumor tissue samples from 39 children with hepatoblastoma. The tumor growth time and volume size were recorded in detail. Simultaneously, 39 children’s data were collected for experimental and clinical analysis. The difference in tumorigenesis rate between different parameters was analyzed by χ2 test (categorical variable). Continuous variables with a normal distribution were compared using the t-test. Results:After cell passage and pathological diagnosis, 21 cases of hepatoblastoma PDX models were successfully constructed, with a success rate of 53.8% (21/39). Tumor samples from each generation of successfully modeled PDX models had pathology results that were consistent with those of the corresponding primary tumors. The analysis of the key factors affecting the tumor formation rate of PDX revealed that the metastasis rate was more successful in primary tumors than in liver in situ tumors (7/8 vs. 14/31, P = 0.049). However, there was no significant difference between tumor formation rates and pathological subtypes. According to the PDX tumor formation group comparison between the primary tumor and the metastatic tumor, there was no statistically significant difference between the two groups in terms of tumor formation time and tumor volume. Hematoxylin-eosin staining in hepatoblastoma’s PDX mouse was consistent with the primary tumor. Immunohistochemistry positivity rates of four proteins, namely hepatocyte antigen (Hepatocyte), phosphatidylinositol glycan 3, β-catenin, and alpha-fetoprotein, in primary tumor tissues and PDX mouse models were 100% vs. 100%, 100% vs. 95.24%, 100% vs. 100%, and 95.24% vs. 85.71%, respectively. Conclusion:A PDX mouse model for hepatoblastoma has been successfully established in children. The tumor formation rate is high, with metastatic tumors having a higher tumor formation rate than primary tumors and transplanted tumors retaining the biological characteristics of primary tumors.
