Objective: To investigate the incidence of adverse events following immunization (AEFI) of human papillomavirus (HPV) vaccines in Hangzhou City from 2017 to 2021, so as to provide insights into safety monitoring and evaluation for HPV vaccines. Methods: The AEFI caused by immunization of bivalent (HPV2), quadrivalent (HPV4) and nonavalent HPV vaccines (HPV9) reported in Hangzhou City from 2017 to 2021 were captured from the AEFI Surveillance Module of Chinese Disease Control and Prevention Information System, and HPV vaccination data were captured from the Zhejiang Municipal Immunization Information Management System. The incidence, temporal distributions and clinical symptoms of AEFI were analyzed. Results: Totally 922 310 doses of HPV vaccines were immunized in Hangzhou City from 2017 to 2021, and 232 cases with AEFI were reported, with an overall incidence rate of 25.15/105 doses. The reported incidence rates of AEFI caused by HPV2, HPV4 and HPV9 vaccination were 31.13/105 doses, 25.93/105 doses and 22.01/105 doses, respectively. General reactions and abnormal reactions were predominant AEFI, and the reported incidence rates of general reactions and abnormal reactions were 21.58/105 doses and 2.60/105 dose, respectively. AEFI predominantly occurred 0 to 1 day post-immunization (165 cases, 71.12%), and the main clinical symptoms included local swelling of injection sites, hard tubercle and fever, with reported incidence rates of 10.30/105 doses, 5.96/105 doses and 6.18/105 doses, respectively. Conclusions Low incidence of AEFI was reported following HPV vaccination in Hangzhou City from 2017 to 2021, and all AEFI were mild. The safety of HPV2, HPV4 and HPV9 remains high.

Objective:To investigate the incidence and its related influencing factors of cervical squamous intraepithelial lesion in patients with repeated uterine prolapse.Methods:A total of 200 patients with grade Ⅲ-Ⅳ repeated uterine prolapse treated by surgery at Jintan Hospital Affiliated to Jiangsu University from January 2017 to June 2019. The patients received vaginal hysterectomy. The clinical data and postoperative pathological results of patients were collected to observe the incidence of cervical squamous intraepithelial lesion, and the influencing factors of cervical squamous intraepithelial lesion were analyzed.Results:Of the 200 patients with grade Ⅲ-Ⅳ repeated uterine prolapse, 20 cases (10.0%) had cervical squamous intraepithelial lesion, including 17 cases of low-grade squamous intraepithelial lesion and 3 cases of high-grade squamous intraepithelial lesion. The differences of age, disease course of uterine prolapse, birth times, proportion of family history of tumor, proportion of cervicitis, high-risk human papillomavirus (HPV) infection rate, classification of uterine prolapse, and the proportion of flushing before husband's sexual life between patients with cervical squamous intraepithelial lesion and patients without squamous intraepithelial lesion were statistically significant (all P < 0.05). The logistic analysis showed that disease course of uterine prolapse ( OR = 2.381, 95% CI 1.337-9.050, P = 0.002), cervicitis ( OR = 1.242, 95% CI 1.113-3.015, P = 0.032), high-risk HPV infection ( OR = 1.425, 95% CI 1.124-6.234, P = 0.020), and uterine prolapse classification ( OR = 1.632, 95% CI 1.204-7.624, P = 0.015) were independent influencing factors associated with cervical squamous intraepithelial lesion in patients with repeated uterine prolapse. Conclusion:The incidence of cervical squamous intraepithelial lesion in patients with repeated uterine prolapse is high, and the risk of cervical squamous intraepithelial lesion is increased in patients with disease course >10 years or grade Ⅳ uterine prolapse.

Objective　To prepare retrovirus which carry GFP gene and are able to label living cells simply and rapidly. Methods　The recombinant retroviral vector pLNCX-GFP was constructed by inserting 780?bp GFP cDNA fragment into the MCS site of retroviral plasmid pLNCX. Both ecotropic packaging cell line ΦX-Eco and amphotropic packaging cell line ΦX-Ampho and PA317 were transfected by pLNCX-GFP with liposome. The supernate collected from transfected packaging cells was used to infect a variety of tumor cell lines and vascular endothelia cell lines. Results　When packaging cells were transfected by retroviral vector pLNCX-GFP, the GFP expression could be observed in 25％～40％ of cells and GFP retrovirus then could be detected, however G418 resistant clones showed more stable GFP expression and higher retrovirus titer. The GFP retrovirus from different packaging cell line showed variant ability to infect tumor cell lines and vascular endothelia cell lines and the tumor cells infected by GFP retrovirus showed stable GFP expression in vitro. GFP transduced tumor cells could grow in syngenic animal and continue expressing GFP. Conclusion　Using GFP retrovirus to label target cells represent an important advantage over conventional plasmid because they can efficiently transfer GFP gene into target cells and GFP can be stably expressed in target cells no matter in vitro or in vivo.

Objective? To explore the effects of Omaha system-based nursing intervention on patients after percutaneous coronary intervention (PCI). Methods? Totally 200 patients receiving PCI in Ningbo First Hospital from February 2016 to November 2017 were selected using convenient sampling and divided into the control group (n=100) and the observation group (n=100) according to the random number table. Patients in the control group received conventional nursing care, while patients in the observation group received nursing care based on Omaha system. The incidence of postoperative vascular complications was evaluated between the two groups. Self-Depression Scale (SDS), Self-Anxiety Scale (SAS) and the nursing satisfaction questionnaire were used to evaluate the effects of intervention. Results? The incidence rate of postoperative vascular complications was lower in the observation group than in the control group (P＜ 0.05); the SAS and SDS scores of the observation group were lower than those of the control group (P＜0.05); and the satisfaction at discharge of the observation group was higher than that of the control group (P＜ 0.05). Conclusions? Omaha system-based nursing interventions can reduce the incidence rate of postoperative vascular complications, ameliorate patients' negative emotions and improve their satisfaction, which is worth promoting in clinical practice.

Objective:To analyze the current situation of researches on the fear of disease progression at home and abroad, and sort out the research hotspots and development context.Methods:The relevant literature about fear of disease progression published by China National Knowledge Infrastructure (CNKI) and Web of Science core collection database were systematiclly searched, and the search period was from January 1, 2002 to June 24, 2022. CiteSpace 5.8.R3 software was used for visual analysis of relevant literature.Results:A total of 340 articles were retrieved from CNKI and 1 199 articles were retrieved from Web of Science core collection database. The countries and institutions with the highest number of international publications were Germany, Technical University of Munich and The University of Sydney, with close cooperation among authors and poor inter-institutional cooperation. Domestic research focused on the influencing factors of fear of disease progression and its relationship with depression, anxiety, social support and quality of life, while foreign research focused on breast cancer and its survivors, depression, anxiety, quality of life, reliability and validity of the questionnaire and the feasibility of intervention.Conclusions:The number of articles published at home and abroad is generally on the rise. Compared with foreign countries, there is still a certain gap in the research on fear of progression in China. In the future, China should timely pay attention to the development trends and hot frontiers in this field internationally, so as to promote the research and development of fear of disease progression in China.

Objective To explore the effect of progressive strength training with TheraBand on lower limb motor function and gait after stroke.Methods Forty-eight hemiplegic stroke survivors were randomly divided into a treatment group and a control group,each of 24.The patients of both groups were provided with the routine rehabilitation training,while the treatment group additionally trained the muscles of the paretic side progressively using Thera-Band elastic belts.Before and after 8 weeks of treatment,both groups were evaluated using the Fugl-Meyer movement assessment (FMA),the Berg balance scale (BBS),and the walking and stair negotiation components of the functional independence measure (FIM).GaitWatch gait analysis was also performed.Results After the treatment,significant improvement was observed with both groups' average FMA scores,BBS ratings,FIM scores,stride frequency,stride length and walking speed,but the treatment group showed significantly greater improvement than the control group,on average.Conclusion Using Thera-Band elastic belts to provide resistance can supplement routine rehabilitation training in improving motor function and walking ability after a stroke.

Objective:To evaluate the role of improved management procedures in placenta accreta spectrum disorders (PAS) and its impact on maternal and infant outcomes.Methods:This retrospective study involved 164 pregnant women who were diagnosed with PAS complicated with placenta previa and delivered at Nanjing Drum Tower Hospital, Nanjing University Medical School from January 2019 to December 2022. All subjects were allocated to pre-improvement group (January 2019 to December 2020, n=96) and post-improvement group (January 2021 to December 2022, n=68). The management was improved in the following five aspects: (1) The time for scheduled delivery was postponed to 37 weeks from 34-36 weeks;(2) Intraoperative cell salvage was encouraged despite autologous blood donation during pregnancy;(3) Original surgical incision was utilized instead of mid-longitudinal incision in the lower abdomen to reduce operative trauma; (4) A lower segment incision of the uterus was not prohibited based on pre-operative PAS classification and intra-operative situation to enter the uterine cavity, even through the placenta instead of pass-by;(5) The interface between lower uterine segment and bladder was dissected before instead of after the baby was born and uterine blood supply was stopped by tourniquet or Scharr forceps. Statistical methods such as t-test, Chi-square test or Fisher exact probability method were used to compare the difference in maternal and infant outcomes between the two groups. Results:After the improvement, the delivery rate beyond 37 weeks decreased significantly [83.3% (80/96) vs 69.1% (47/68), χ 2=4.60, P=0.038]. There was no significant difference in the distribution of elective, subemergency and emergency surgeries before and after the improvement ( χ 2=0.36, P=0.834). Compared to the pre-improvement group, the proportion of women who underwent cesarean section through previous abdominal incisions increased significantly [74.0% (71/96) vs 91.1% (64/68), χ 2=11.11, P=0.001] in the post-improvement group, while the proportion of application of abdominal longitudinal incision and classical cesarean section decreased significantly [84.3% (81/96) vs 57.3% (39/68), χ 2=14.81, P<0.001; 83.3% (80/96) vs 61.8% (42/68), χ 2=9.72, P=0.003]. No significant difference was found between the two groups in terms of the transfusion rate of allogeneic red blood cell, platelet and other blood components, pre-discharge hemoglobin level, subtotal hysterectomy rate, bladder injury, thrombus event, the admission rate of intensive care unit and unplanned reoperation rate (all P>0.05). The incidence of admission in neonatal intensive care unit (NICU) and necrotizing enterocolitis decreased significantly after improvement [24.7% (24/97) vs 11.8% (8/68), χ 2=4.31, P=0.038; 4.1% (4/97) vs 0.0% (0/68), χ 2=58.06, P<0.001]. The incidence of respiratory distress syndrome, mechanical ventilation, and neonatal septicemia also decreased, but without statistical difference. Conclusions:After adopting a series of improvement measures, such as delaying planned delivery to 37 weeks of gestation, individualized cesarean section plan, and changing the method of obtaining autoblood, the number of premature infants and the NICU admission rate decreased significantly without increasing the risk of maternal complications and emergency operation. Furthermore, the incidence of adverse events such as maternal organ injury, unplanned reoperation, and re-admission remains at a low level. Therefore, this improved management is feasible.

Objective:To analyze the influencing factors of death in patients with acute respiratory distress syndrome (ARDS) combined with acute kidney injury (AKI) in intensive care unit (ICU) after continuous renal replacement therapy (CRRT).Methods:The demographic and clinical data of ICU patients with ARDS combined with AKI after CRRT at Henan Provincial People's Hospital from January 1, 2018 to December 31, 2018 were collected. According to the final treatment results of this hospitalization, the patients were divided into death group and survival group. Survival was defined as the improved patient's condition and hospital discharge. Death was defined as the patient's death during the ICU hospitalization or confirmed death after abandoning treatment and automatically being discharged from the hospital in the follow-up. The basic clinical characteristics and CRRT status between the two groups were compared. Multivariate logistic regression method was used to analyze the influencing factors of death in patients.Results:A total of 132 patients were enrolled, of which 90 patients (68.2%) died, with 84 males (63.6%) and median age of 59(45, 73) years. Compared with the survival group, the death group had higher age, proportion of malignant tumors, sequential organ failure assessment (SOFA) score, number of organ dysfunction and proportion of positive balance of fluid accumulation at 72 hours, longer time from entering ICU to CRRT, and lower mean arterial pressure (minimum value) and oxygenation index (all P<0.05). Multivariate logistic regression analysis results showed that the age≥60 years old ( OR=4.382, 95% CI 1.543-12.440, P=0.006), large number of organ dysfunction ( OR=1.863, 95% CI 1.109-3.130, P=0.019), high SOFA score ( OR=1.231, 95% CI 1.067-1.420, P=0.004) and long time from ICU admission to CRRT ( OR=1.224, 95% CI 1.033~1.451, P=0.020) were independent influencing factors of death in patients with ARDS combined with AKI after CRRT, and high oxygenation index ( OR=0.992, 95% CI 0.986-0.998, P=0.010) was an independent protective factor for patients' prognosis. Conclusions:The mortality of patients with ARDS combined with AKI after CRRT is still high. The age≥60 years old, large number of organ dysfunction, high SOFA score and long time from ICU admission to CRRT are independent influencing factors for death, and high oxygenation index is an independent protective factor for prognosis in patients with ARDS combined with AKI after CRRT.
