ObjectiveTo investigate the current status and related factors of maternal influenza vaccination willingness among pregnant and postpartum women in Shanghai and Liaoning Province, China, and to explore the facilitators and barriers affecting vaccination uptake, so as to provide references for future practices in promoting maternal influenza immunization in China. MethodsA convergent mixed-methods research was conducted. From January to March 2024, a questionnaire survey was conducted among women attending prenatal and postnatal care at 7 medical institutions in Shanghai and Dalian, Liaoning Province, which aimed to assess pregnant women’s knowledge about influenza vaccine and their willingness to vaccination during pregnancy, as well as to identify the related factors. In addition, purposive sampling method was used to conduct in-depth interviews with pregnant women and perinatal healthcare service providers to explore their perspectives on influenza vaccination during pregnancy, including the reasons for their willingness or unwillingness to receive ( or recommend) the vaccine, and the relevant facilitators and barriers to vaccination. ResultsA total of 366 pregnant and postpartum women participated in the questionnaire survey, and 9.56% (35/366) of them were willing to receive the influenza vaccine during pregnancy. The results of multivariate logistic stepwise regression analyses showed that primipara (aOR=0.158, 95%CI: 0.037‒0.671, P=0.012), family members’ support for influenza vaccination during pregnancy (aOR=0.015, 95%CI: 0.003‒0.082, P<0.001) were associated with higher willingness to receive influenza vaccine during pregnancy. Absence of influenza infection during pregnancy (aOR=5.383, 95%CI: 1.801‒16.092, P<0.001), and lack of knowledge regarding influenza vaccination during pregnancy (aOR=11.294, 95%CI: 3.593‒35.496, P<0.01) were associated with lower willingness to receive influenza vaccine during pregnancy. Qualitative findings indicated that the facilitators to vaccination willingness among pregnant and postpartum women included the recommendation of healthcare service providers, adequate knowledge of influenza vaccine information and family members’ support for vaccination. Conversely, the barriers to vaccination willingness included low recommendation from the healthcare service providers, lack of knowledge about the safety of influenza vaccine during pregnancy and inadequate attention to influenza and influenza vaccine. ConclusionThe willingness to receive influenza vaccination among pregnant and postpartum women in Shanghai and Liaoning Province is relatively low. It is recommended that China should promptly improve the evidence-based system for the safety and efficacy of influenza vaccines for pregnant and postpartum women, along with an establishment of the mechanism for addressing adverse reactions. Furthermore, it is essential to enhance educational outreach to pregnant and postpartum women, their families, and healthcare service providers, thereby increasing the accessibility of information regarding influenza vaccination, which are expected to enhance the willingness of pregnant and postpartum women to receive the vaccine.

Objective To explore the application value of indocyanine green (ICG)in sentinel lymph node biopsy(SLNB)for breast cancer.Methods A total of 160 patients with breast cancer in our hospital from January 2013 to December 2015 were analyzed,who were randomly divided into methylene blue group(n =65)and methylene blue plus ICG group(n =95).The success rate of detection,accuracy and false negative rate between two groups were compared.Results The success rate of detection and accuracy in methylene blue plus ICG group was significantly higher than thoase in methylene blue group,with statistically significant difference(P <0.05).The false negative rate of methylene blue plus ICG group was significantly lower than that of methylene blue group,with statistically significant difference (P <0.05).The number of sentinel lymph node in methylene blue plus ICG group was (2.9 ±0.9)/case which was more than (1.9 ± 0.5)/case in methylene blue group ,with statistically significant difference(P <0.05).The length of opertion of methylene blue plus ICG group was obviously shorter than that of methylene blue group.Conclusion Indocyanine green used in the sentinel lymph node detection for breast cancer can provide a reliable basis and reduce the false negative rate,who improves the level of diagnosis of breast cancer.

ObjectiveTo evaluate the effectiveness of surgical technique improvement in thyroid lobectomy for prevention of recurrent laryngeal nerve (RLN) injury. MethodsThe clinical data of 85 patients of thyroid disease undergoing 126 lobectomies from Jan 2010 to Jan 2011 were retrospectively analyzed.All patients undergone accurate thyroid lobectomy with accurate envelop anatomic dissection,skeletonized blood vessels. Recurrent laryngeal nerve was all dearly exposed.ResultsNo-bleeding surgical area was achieved.The RLN was exposed.Unilateral temporary RLN injury occurred in 2 cases.The rate of RLN injury was 1.59％(2/126). There was no bilateral and perpetual RLN injury.ConclusionsCarrying through the accurate thyroid lobectomy,the incidence of RLN injury is low.

Objective To study the toxicity and efficacy of induction chemotherapy followed by concurrent cisplatin chemotherapy and three dimensional conformal radiotherapy (3DCRT) for inoperable locally advanced non-small cell lung cancer (LA-NSCLC). Methods Totally 76 patients with LA-NSCLC received two cycles induction chemotherapy followed by 3DCRT with a median dose of 68 Gy (64 to 74 Gy).During the 3DCRT, cisplatin (25 mg/m2, weekly) was given intravenously for 6-7 times. Results The CR rate, PR rate and overall response rate of induction chemotherapy were 3% ,42% and 45%. After the concurrent chemoradiation, the corresponding figures were 10%, 62% and 72%. The median survival time (MST) and median progression-free survival (PFS) of all patients were 16.6 months and 10.3 months. The 1-, 2- and 3-year overall survival (OS) and PFS rates were 67% , 35% , 21% and 42% , 15%, 6%. Of patients with stage ⅢA and stage ⅢB disease,the MST were 19.7 months and 15.6 months, the PFS were 10.8 months and 9.4 months. The major treatment-related toxicities included radiation esophagitis, radiation pneumonitis, nausea ( or vomiting) and leukopenia. The major pattern of treatment failure was distant metastasis. Forty-five patients (59%) experienced the local recurrence or/and distant metastasis, including 4 (9%) with in-field failure, 38 (84%) distant metastasis and 3 (7%) malignant pleural effusion. Conclusions Induction chemotherapy followed by concurrent weekly cisplatin and 3DCRT for inoperable locally advanced NSCLC results in encouraging outcomes and acceptable tolerance.
