OBJECTIVE To evaluate the accuracy of three individualized drug delivery tools， i.e. JPKD， SmartDose and NextDose， in predicting tacrolimus dose and blood concentration after kidney transplantation， and analyze the influential factors of prediction accuracy. METHODS The clinical data of adult hospitalized patients treated with tacrolimus after kidney transplantation from January 2021 to June 2023 were retrospectively collected. Three individualized dosing tools， i.e. JPKD， SmartDose and NextDose， were used to predict the dose and plasma concentration of tacrolimus. The absolute prediction error （APE） and prediction error （PE） between the measured value and the predicted value， and prediction success rate were calculated （APE＜30% indicating a good forecast）. Pearson assay or Spearman assay was used to analyze the correlation between the predicted dosage and actual dosage， as well as the predicted and measured blood concentration values using three software； univariate analysis was used to investigate the influential factors for prediction accuracy of JPKD， SmartDose and NextDose. RESULTS A total of 110 hospitalized patients were included in this study， and tacrolimus doses and plasma concentrations were monitored. The predicted doses of JPKD， SmartDose and NextDose were （2.0±0.7）， （2.7±1.9）， （1.8±0.8） mg， their measured value was （1.9±0.6） mg， and the correlation coefficients between the predicted values and the measured value were 0.841， 0.450， 0.247 （P＜0.001）； the median APEs were 6.00%， 52.07% and 30.40%， and the median PEs were 5.00%， 18.50% and －3.50%； the prediction success rates were 98.45%， 30.05% and 49.22%. The predicted values of tacrolimus concentrations using JPKD， SmartDose， NextDose were （6.74±3.36）， （6.93±5.02）， 9.00（5.80±12.60） ng/mL， the measured value was 8.64（7.11，9.77） ng/mL， and the correlation coefficients between the predicted values and the measured value were 0.997 （P＜0.001）， －0.066 （P＝0.360）， 0.920 （P＜0.001）. The median APEs were 5.54%， 45.91% and 35.56%， and PEs were －4.94% （median）， －17.050% （median） and 36.93% （average value）； the prediction success rates were 97.93%， 32.64% and 37.31%. Univariate analysis showed that the dosage， blood concentration， body weight， transplantation time and others were related to the prediction accuracy （P＜0.05）. CONCLUSIONS The good prediction rates of tacrolimus dose and blood concentration in kidney transplant patients using three personalized drug delivery tools， from high to low， are JPKD， NextDose， and SmartDose， suggesting that JPKD can be prioritized in clinical use.

Objective : To investigate the awareness of human papillomavirus ( HPV ) vaccine and willingness to vaccinate daughters among parents of primary and middle school students, so as to provide the reference for the promotion of HPV vaccine in primary and middle school girls. Methods : Using multi-stage stratified cluster sampling method, the parents of girls in in Grade Four to Nine from schools in Gongshu District of Hangzhou, Xiuzhou District of Jiaxing and Wuxing District of Huzhou were selected. A questionnaire survey was conducted to collect demographic information, HPV vaccine related knowledge and willingness to vaccinate daughters with HPV vaccines. The multivariate logistic regression model was used to analyze the influencing factors for the willingness to vaccinate daughters with HPV vaccines among parents. Results : Totally 1 500 questionnaires were sent out, and 1 466 were effectively collected, with an effective rate of 97.73%. There were 313 fathers responded, accounting for 21.35%; and 1 153 mothers responded, accounting for 78.65%. The awareness rate of HPV vaccine was 16.81%. The rate of willing to vaccinate daughters with HPV vaccines was 49.86%. The multivariate logistic regression analysis showed that the patients who ever vaccinated daughters with self-paid vaccines ( OR=1.935, 95%CI: 1.473-2.541 ), knew cervical cancer ( OR=1.424, 95%CI: 1.065-1.904 ), knew HPV vaccine dose ( OR=1.672, 95%CI:1.216-2.301 ), knew the best vaccination period ( OR=1.392, 95%CI: 1.032-1.876 ), knew the need of cervical cancer screening even after vaccination ( OR=1.596, 95%CI:1.227-2.075) were more willing to vaccinate daughters with HPV vaccines, while the parents who thought HPV vaccine expensive ( OR=0.154, 95%CI: 0.099-0.240 ) were less willing to vaccinate daughters with HPV vaccines. Conclusions The rates of HPV vaccine awareness and willingness to vaccinate daughters are 16.81% and 49.86% among parents of primary and middle school students. Their knowledge of HPV vaccine and the price of the vaccine may affect their willingness to vaccinate daughters.

Vaccine hesitancy has spread worldwide recent years and resulting in increasing incidence of some well-controlled vaccine-preventable diseases, which is extremely unfavorable to the consolidation of the national immunization programme and the elimination of corresponding diseases. Based on the Complacency, Convenience and Confidence ("3Cs") model of vaccine hesitancy, combined with the practice experience of management of quality control through the whole vaccine life cycle in China, we introduce a framework of vaccine hesitancy monitoring and early warning in China to provide a reference for carrying out corresponding work. The indicator system of the framework derives from monitoring of vaccine life cycle quality management, population vaccine confidence, and service availability.

Bombyx mori is a lepidopteran insect with important economic value. Bombyx mori nucleopolyhedrovirus (BmNPV) causes huge economic loss to silkworm industry in China every year. The objective of this study is to determine the anti-BmNPV mechanism of Bombyx mori strain NC99R, and to provide a basis for understanding the molecular mechanism of the silkworm resistance strain. The normal control Dazao (DZ) strain and the NC99R resistant strain were fed with occlusion bodies (OB). The median lethal dose (LD50) analysis of the DZ and NC99R showed that the LD50 of DZ was 1.2×10⁵ OBs/larva, while NC99R was 1.8×10⁶ OBs/larva. The LD50 of the NC99R was about 15 times higher than the DZ. The mortality of DZ and NC99R were analyzed, which were fed with 1×10⁶ OBs/larva and injection with 1×10⁶ BVs/larva. The results showed that the death peak of DZ was concentrated in the 4th to 6th day. And the death peak of NC99R was concentrated in the 6th to 8th day, with a delay of 1-2 days compared with the control. The BmNPV DNA copy number showed that the BmNPV genome in DZ proliferated rapidly. The copy number of BmNPV DNA in NC99R were increased slowly after oral infection and body injection. HE staining showed that midgut tissue has no significant difference between DZ and NC99R in the early stage of oral infection. At 96 h p.i., the nucleus of DZ midgut became larger and shedding. The NC99R had enlarged nuclei, but the cells were still arranged neatly. Finally, the expression of virus genes in different periods were analyzed by RT-PCR. The results indicated that the immediate early gene ie-1 expression levels began to down-regulate after 24 h p.i.. The early, late, and extremely late genes were also down-regulated, and finally maintained at a lower expression level.

Objective: To evaluate the safety of enterovirus 71（EV71）inactivated vaccines produced by Wuhan Institute of Bio Products through learning the incidence of adverse events following immunization（AEFI）in children aged 6 months to 3 years old after vaccination. Methods: According to the national requirement for vaccine safety monitoring program，data of AEFI cases after inoculated EV71 vaccines from September 2017 to October 2018 in Zhejiang Province was collected by combining active and passive monitoring. Demographic characteristics，space distribution，dose and incidence of AEFI were analyzed. Results: A total of 107 503 children were included in this study，of which 27 173 were actively monitored and 80 330 were passively monitored. The monitoring results showed that 288 cases of AEFI occurred after inoculated EV71 vaccines，the reported incidence rate was 267.90/100 000. Of 288 cases，266 cases had common reactions（247.43/100 000），14 cases had abnormal reactions（13.02/100 000）and 8 cases had complications（7.44/100 000）；145 cases were passively monitored（180.51/100 000）and 143 cases were actively monitored（526.26/100 000）；150 cases were males and 138 cases were females，with the males to females ratio of 1.09∶1. The AEFI of EV71 vaccines were reported in all the cities of Zhejiang Province，with Jinhua，Taizhou and Hangzhou ranking the top three and accounting for 50.69% of all the reported cases. About 202 cases of AEFI（70.14%）occurred after the first dose of EV71 vaccines，and 163 cases（56.60%）occurred on the day of inoculation.Most of common reactions were fever，swelling and sclerosis. The harm of the reported abnormal reactions was mild，with 8 cases of anaphylactic rash and no other serious abnormal reactions were found. Conclusion The reported incidence rate of AEFI of the domestic EV71 vaccine in children aged from 6 months to 3 years is 267.90/100 000，without serious abnormal reactions，suggesting that the EV71 vaccine is safe.

Objective: To evaluate the post-marketing safety of inactivated Enterovirus type 71 (EV-A71) vaccine (human diploid cell) . Methods: A total of 20 191 healthy children aged 6 to 59 months were invited to receive 2 doses of EV-A71 vaccine in Zhejiang Province from September 2016 to December 2017. Child caregivers were followed up on the 4^th or 5^th day after each EV-A71 vaccination, and the incidence of local, systemic, and other adverse events within 3 days after vaccination was recorded to assess vaccine safety. Describe the differences in adverse events among children with different characteristics. Results: A total of 32 230 doses were observed in this study, of which 20 191 and 12 039 were vaccinated for the first and the second dose, respectively; and the incidence of adverse events within 3 days was 2.045% (413 doses) and 1.611% (194 doses), respectively. After the first and the second dose, the number of systemic adverse events was the highest, 371 and 175 cases, respectively, with an incidence of 1.837% and 1.454%, respectively; the number of local adverse events was the lowest, 14 and 2 doses, respectively, with an incidence of 0.069% and 0.017%. Local adverse events occurred after vaccination were generally mild, and only 2 patients had level of 3; among the systemic adverse events, 39 patients had a fever level of 3 or higher, accounting for 8.2% of the total fever. Most of the symptoms in the local adverse events did not require treatment, only 3 cases of vaccination site rash and 2 cases of pruritus were self-purchased drugs or outpatient treatment; except for 5 cases of fever, the other symptoms were not hospitalized in the case of systemic adverse events. Conclusion The incidence of adverse events within 3 days after vaccination with EV-A71 vaccine was low in children, mainly systemic adverse events, and the prognosis was good.
