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 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 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 investigate the incidence of acute kidney injury (AKI) following pancreaticoduodenectomy and related risk factors in elderly patients.Methods:The clinical data of elderly patients who underwent pancreaticoduodenectomy in Henan Provincial People′s Hospital from January 2017 to June 2020 were collected retrospectively. According to the changes of serum creatinine within 48 h or 7 days after operation, the patients were divided into AKI group and non-AKI group. The basic clinical characteristics of the two groups were compared, and the incidence of AKI was calculated. Multivariate logistic regression model was used to analyze the risk factors of postoperative AKI.Results:A total of 322 elderly patients were enrolled, with age of (67.1±5.2) years old (60-85 years old) and 186 males (57.76%). Among 322 elderly patients, there were 41 patients (12.73%) suffering from AKI following pancreaticoduodenectomy. Compared with the non-AKI group, the level of bilirubin in AKI group was higher ( Z=-2.012, P=0.044), and the level of hemoglobin in AKI group was lower ( Z=-2.111, P=0.035). Multivariate logistic regression analysis showed that increased preoperative total bilirubin ( OR=1.003, 95% CI 1.000-1.006, P=0.027) and postoperative exploratory laparotomy ( OR=3.936, 95% CI 1.071-14.460, P=0.039) were the independent influencing factors for AKI after pancreaticoduodenectomy in elderly patients. Conclusions:The incidence of AKI after pancreaticoduodenectomy in elderly patients is 12.73%. Preoperative high bilirubin and postoperative exploratory laparotomy may be the independent risk factors for AKI after pancreaticoduodenectomy in elderly patients.

Objective:To observe any effect of body-weight-supported treadmill training (BWSTT) combined with functional electrical stimulation (FES) on lower limb motor function and the walking ability of hemiplegic stroke survivors.Methods:Fifty-eight stroke survivors with hemiplegia were randomly divided into an FES group of 19, a BWSTT group of 19 and a combination group of 20. In addition to their early routine rehabilitation therapy, the FES and BWSTT groups were provided with the respective therapies, while the combination group received both. The three groups received 30 minutes of treatment a day, 5 days a week for 8 weeks. The Berg Balance Scale (BBS), the simplified version of the Fugl-Meyer assessment scale for the lower extremities (FMA-LE), the 10-metre walk test (10MWT) and functional ambulation classification (FAC) were used to evaluate the subjects′ balance, lower-limb motor function, walking speed and walking function before and after the 8 weeks of treatment.Results:After the treatment, the average BBS, FMA-LE, 10MWT and FAC scores of all three groups had improved significantly, but the combination group′s averages were then significantly better than those of the other two groups.Conclusions:BWSTT combined with FES can best improve the balance, lower-limb motor functioning and walking of hemiplegic stroke survivors.

Objective:To investigate the clinical characteristics, treatment and prognosis of primary vitreoretinal lymphoma (PVRL) diagnosed and treated in our hospital during the past 10 years.Methods:A retrospective clinical study. From 2011 to 2021, 126 eyes of 67 patients with PVRL who were diagnosed and treated in Department of Ophthalmology, Eye-ENT Hospital, Fudan University were included in the study. Among them, there were 23 males (34.3%, 23/67) and 44 females (65.7%, 44/67); the average age was 57.1 years. There were 59 cases with both eyes (88.1%, 59/67) and 8 cases with one eye (11.9%, 8/67). At the initial eye diagnosis, 22 cases had a clear history of primary central nervous system lymphoma (PCNSL); 5 cases were found to have intracranial lesions by head imaging examination; 40 cases had no central nervous system involvement. Twenty cases were treated with glucocorticoids due to misdiagnosed uveitis. All patients received intravitreal injection of methotrexate (IVM) treatment. The treatment regimen was twice a week in the induction period for 2 weeks, once a week in the consolidation period for 1 month, and once a month in the maintenance period. Patients with PCNSL or both eyes received concurrent systemic chemotherapy (chemotherapy), and some in combination with radiation therapy to the brain (radiotherapy). The mean follow-up time was 39.3 months. The clinical manifestations, treatment and prognosis of the patients were retrospectively analyzed. The visual acuity before and after treatment was compared by t test. Results:Among the 22 cases with a clear history of PCNSL at the initial eye diagnosis, the average time from intracranial diagnosis to eye diagnosis was 22.9 months. Among the 40 cases without central nervous system involvement at first, 14 cases (20.9%, 14/67) developed central nervous system lesions during follow-up period. The mean time from ocular diagnosis to intracranial diagnosis was 9.9 months. Among the 126 eyes, 42 eyes (33.3%, 42/126) had anterior segment inflammation. vitreous inflammation type, retinal type, and vitreous retinal type were 58 (46.0%, 58/126), 7 (5.6%, 7/126), and 61 (48.4%, 61/126) eyes, and 9 of them (7.1%, 9/126) had optic nerve involvement at the same time. Patients received an average of 12 IVM treatments. IVM combined with systemic chemotherapy in 59 cases (88.1%, 59/67), of which 16 cases were combined with brain radiotherapy. All patients achieved complete remission after completing the treatment cycle (100.0%, 67/67). After treatment, 21 eyes (16.7%, 21/126) had ocular recurrence; 22 (32.8%, 22/67) had intracranial recurrence; 8 cases (11.9%, 8/67) died. The mean progression-free survival of patients was 23.7 months; the mean survival time was 43.6 months; the 5-year overall survival rate was 72.5%.Conclusions:The manifestations of PVRL are complex and diverse, and most of them are accompanied by involvement of the central nervous system. It can be divided into vitreitis type, retinal type and vitreoretinal type, and the optic nerve can be involved at the same time; IVM combined with systemic treatment can completely relieve the disease.
