Objective:To investigate the current situation of kinesiophobia in patients with in vitro fertilization and embryo transfer and to analyse its influencing factors, so as to provide a reference for the intervention research on kinesiophobia in patients with embryo transfer.Methods:Patients in the first trimester of pregnancy after in vitro fertilization and embryo transfer in the Women's Hospital, School of Medicine, Zhejiang University from August to October 2024 were selected by convenience sampling method, and the general information questionnaire, Tampa Scale of Kine-siophobia (TSK), General Perceived Self-Efficacy Scale (GSES), the Brief Illness Perception Questionnaire (BIPQ) and Social Support Rating Sca1e (SSRS) were used as research tools for cross-sectional investigation, and the influencing factors were analysed by univariate and multiple linear regression.Results:A total of 318 pregnant women in the early stage were finally included, with an average age of (33.11 ± 4.55) years old. The TSK score was (40.40 ± 4.22) points, the GSES score was (25.64 ± 5.25) points, the BIPQ score was (34.30 ± 9.97) points, the SSRS score was (37.98 ± 5.65) points, among which 79.25%(252/318) cases had kinesiophobia. Multiple linear regression analysis showed that age, educational level, exercise frequency before transplantation, self-efficacy, and disease perception were important influencing factors of kinesiophobia in the early pregnancy of in vitro fertilization-embryo transfer patients ( t values were -3.39 to 3.11, all P<0.05). Conclusions:The incidence of kinesiophobia in embryo transfer patients is at a medium to high level, and nursing staff should pay attention to patients with young age, low education level and low daily exercise, and at the same time improve patients′self-efficacy and control of disease perception, reduce the occurrence of kinesitophobia in early pregnancy, improve mental state during pregnancy and promote their health.

Background::Chemotherapy plus granulocyte colony-stimulating factor (GCSF) regimen is one of the available approaches to mobilize peripheral blood progenitor cells (PBPCs). It causes thrombocytopenia and delays leukapheresis. This study aimed to evaluate the role of recombinant human thrombopoietin (rhTPO) before mobilization chemotherapy in facilitating leukapheresis in patients with lymphoma.Methods::In this randomized open-label phase 2 trial, patients were randomly assigned in a 1:2 ratio to receive mobilization with rhTPO plus GCSF in combination with chemotherapy (the rhTPO plus GCSF arm) or GCSF alone in combination with chemotherapy (the GCSF alone arm). The recovery of neutrophils and platelets and the amount of platelet transfusion were monitored.Results::Thirty patients were enrolled in this study between March 2016 and August 2018. Patients in the rhTPO plus GCSF arm (n = 10) had similar platelet nadir after mobilization chemotherapy ( P=0.878) and similar amount of platelet transfusion (median 0 vs. 1 unit, P=0.735) when compared with the GCSF alone arm (n = 20). On the day of leukapheresis, the median platelet count was 86 × 10 9/L (range 18-219) among patients who received rhTPO and 73 × 10 9/L (range 42-197) among those who received GCSF alone ( P=0.982). After the use of rhTPO, the incidence of platelet count <75 × 10 9/L on the day of leukapheresis did not decrease significantly (30.0% vs. 50.0%, P=0.297). Platelet recovery after PBPC transfusion was more rapid in the rhTPO plus GCSF arm (median 8.0 days [95% confidence interval 2.9-13.1] to platelets ≥50 × 10 9/L vs. 11.0 days [95% confidence interval 8.6-13.4], P=0.011). The estimated total cost of the mobilization and reconstitution phases per patient was similar between the two treatmtent groups ( P=0.362 and P=0.067, respectively). Conclusions::Our findings indicate that there was no significant clinical benefit of rhTPO use in facilitating mobilization of progenitor cells, but it may promote platelet recovery in the reconstitution phase after high-dose therapy.Trial registration::This trial has been registered in Clinicaltrials.gov as NCT03014102.

Objective:To evaluate the application effect of problem-based learning (PBL) combined with tutorial system mode in the capacity of literature retrieval and academic writing in specialist nurses of assisted reproductive technology (ART).Methods:A total of 61 ART nurse specialists trained in Women's Hospital, School of Medicine, Zhejiang University from 2017 to 2018 were recruited in the study. These specialist nurses were trained with PBL combined with tutorial system mode during the training. Nursing Research Capacity of Self-Evaluation Scale and questionnaires were used to evaluate the capacity of literature retrieval and academic writing before and after the training. The data was analyzed by SPSS 19.0.Results:After the training, the total score of nursing research capacity was significantly higher than before ( P<0.05), and the capacity of literature retrieval, the publication number of papers and research projects were also higher than before ( P<0.01). Conclusion:PBL combined with tutorial system is an effective way to improve the capacity of literature retrieval and academic writing of ART clinical specialist nurses.

OBJECTIVETo investigate the relationship between serum/follicular fluid fetuin B levels and outcome offertilization (IVF).

METHODSInfertility women (28 with low fertilization rates, 44 with normal fertilization rates) receiving IVF in Women's Hospital of Zhejiang University School of Medicine during June and December 2016 were enrolled in the study. Serum/follicular fluid fetuin B levels were measured with ELISA method. Correlations of serum and follicular fetuin B level with fertilization outcome of IVF were analyzed with Pearson correlation coefficient and receiver operating characteristic (ROC) curve.

RESULTSA positive correlation between serum fetuin B and follicular fluid fetuin B levels was observed (=0.675,<0.01). Both serum and follicular fluid fetuin B levels in women with low fertilization rates of IVF were lower than those in women with normal fertilization rates[(6.09±1.31) μg/mL vs. (7.13±1.47) μg/mL,=3.050,<0.05; (5.13±0.96)μg/mL vs. (6.22±1.33) μg/mL,=3.755,<0.01]. ROC analysis showed that the area under curve (AUC) of serum fetuin B level in predicting fertilization rate was 0.832 (95%:0.729-0.934,<0.01), and 6.08 μg/mL could be used as cut-off value.

CONCLUSIONSSerum fetuin B level is correlated with follicular fluid fetuin B level, and it may be used for predicting the fertilization outcome of IVF.
