Pediatric vertigo presents with complex etiologies, and its clinical diagnosis and management can be challenging due to children's limited ability to describe their symptoms. Recurrent vertigo episodes in children, who are at a critical stage of development, can readily lead to emotional disorders in both the children themselves and their guardians. This article reports a case of benign paroxysmal vertigo of childhood（BPVC） in a child who sought care from multiple providers. The child was found to have a patent foramen ovale（PFO） and mild emotional disorder. By analyzing challenges encountered during the diagnostic and management process in this case of recurrent pediatric vertigo, this study provides practical guidance for rational selection of diagnostic techniques and the comprehensive assessment of disease status in pediatric vertigo/dizziness.

Objective:To analyze the pregnancy outcomes in patients with positive anti-centromere antibodies(ACA)receiving in vitro fertilization(IVF)-embryo transfer(ET)and natural conception.Methods:A case-control study was used to retrospectively analyze the clinical data of 3955 patients who received IVF-ET therapy and had the results of antinuclear antibody(ANA)spectrum at Zhejiang Provincial People's Hospital from June 2016 to June 2023.Patients with positive ACA and negative ACA were matched at a ratio of 1∶3 using propensity score matching.Embryo outcomes of IVF were compared between the two groups,and the impact of different fertilization methods and the use of immunosuppressants on pregnancy outcomes were analyzed using self-matching.The natural conception and disease progress were followed up for ACA-positive patients after IVF failure.Results:The ACA-positive patients accounted for 0.86%of all IVF patients(34/3955)and 2.51%of total ANA-positive IVF patients.Regardless of whether patients received conventional IVF(c-IVF)or intracytoplasmic sperm injection(ICSI),the ACA-positive group exhibited significant differences in oocyte maturity and fertilization compared to the ACA-negative group(both P＜0.01).Moreover,the ACA-positive group had a decreased number of D3 suboptimal embryos and D3 optimal embryos(both P＜0.05).In 5 cases of ACA-positive patients who underwent ICSI cycles,the two pronucleus(2PN)rate did not increase compared to c-IVF cycles(P＞0.05),and there was a decrease in the number of D3 high-quality embryos and D3 suboptimal embryos(both P＜0.05).After 1-2 months of immuno-suppressant treatment,12 ACA-positive patients underwent c-IVF/ICSI again,and there were no changes in egg retrieval and fertilization before and after medication(both P＞0.05),but there was an improvement in the 2PN embryo cleavage rate(P＜0.05).The number of embryos transferred was similar between the ACA-positive and negative groups,but the ACA-positive group had significantly lower embryo implantation rate and clinical pregnancy rate compared to the ACA-negative group(both P＜0.05),with no significant differences in the miscarriage rate between the two groups(P＞0.05).Twenty-seven ACA-positive patients attempted natural conception or artificial insemination after IVF failure,resulting in a total of 7 cases of clinical pregnancy.Conclusions:Serum ACA positivity may disrupt oocyte maturation and normal fertilization processes,with no improvement observed with ICSI and immunosuppressant use.However,ACA-positive patients may still achieve natural pregnancy.

Objective To analyze the effect of Meleis transition theory in the intervention of family caregivers of advanced lung cancer patients.Methods From January 2022 to June 2023,94 patients with advanced lung cancer and their family caregivers treated in 4 hospitals of a tertiary A hospital in Zhejiang Province were selected by convenience sampling method,and they were divided into a control group(n=47)and an experimental group(n=47)according to random number table method.The family caregivers of the experimental group received a four-week intervention based on the Meleis transition theory on the basis of routine nursing education,including role recognition,disease knowledge,life care,psychological support,and social resource connection.Family caregivers in the control group received routine nursing education,caregiving education and guidance.The differences in the readiness,caring ability,psychological burden and patients'quality of life were compared between the 2 groups.Results There was no lost follow-up cases in the control group and experimental group.After intervention,the preparation,ability,and quality of life of family caregivers in the experimental group were better than those in the control group,and the psychological burden of caregivers was significantly lower than that in the control group(P＜0.05).Conclusion The intervention of caregiving ability of family caregivers based on Meleis transition theory can effectively improve the caregiving ability of caregivers,reduce the psychological burden of caregivers,improve the quality of care,and improve the quality of life of patients.

Objective:This study aimed to evaluate the global research landscape, identify trends, and determine hotspots concerning hepatoma recurrence post-liver transplantation.Methods:We conducted a bibliometric analysis usinga systematic search was conducted in the Web of Science Core Collection database from Jan. 1992 to Oct. 2023 to identify relevant articles on hepatoma recurrence after liver transplantation. Articles were selected based on inclusion and exclusion criteria and analyzed for publication trends by country/region, journal, author, institution, citation, and keyword. Visualization tools such as Citespace, VOSviewer, and Bibliometric.com were utilized for statistical analysis, identification of emerging trends, and clustering of keyword co-occurrence.Results:Out of 4,936 articles retrieved, 1,189 were included in the final analysis. There was a notable increase in publications on hepatoma recurrence following liver transplantation from 1992 to 2021, peaking in 2021 both globally (n=103) and nationally (n=32). China has the largest number of publications in this field (n=308), maintaining significant collaboration with the United States, South Korea, Japan, Canada. 'Liver Transplantation’ journal had the highest number of publications (n=113). Zhejiang University was the leading institution (n=74), with Academician Zheng Shusen being the most prolific scholar (n=76 publications). Citation emergence detection found that Italian scholar Mazzaferro's Predicting survival after liver transplantation in patients with hepatocellular carcinoma beyond the Milan criteria: a retrospective, exploratory analysis published on The Lancet Oncology in 2009 had the highest burst strength (36.98). Five bursting keywords were identified: alpha fetoprotein, model, validation, sorafenib, and risk. Cluster analysis of keyword co-occurrence revealed five primary research themes: the medication for hepatocellular carcinoma recurrence after liver transplantation, recipient selection criteria, prognostic factors, development and validation of recurrence prediction model, and local treatments for hepatocellular carcinoma.Conclusions:The study underscores rapid advancements in the research on hepatocellular carcinoma recurrence post-liver transplantation over the past three decades, with significant contributions from Chinese scholars, particularly from Zhejiang University and Academician Zheng Shusen. The evolving research hotspots have shifted from transplantation experiences and recipient selection criteria to early post-transplant recurrence risk prediction and therapeutic strategy development.

Idiopathic pulmonary fibrosis (IPF) is a chronic debilitating lung disease with unknown etiology, complex syndromes and prolonged illness, which is difficult to cure. Based on the theory of "spleen is the envoy" in Huang Di Nei Jing, this article explained the TCM meaning of "spleen is the envoy" and the relationship between spleen and other four organs, especially the relationship between spleen and lung. It is believed that the onset of IPF is due to deficiency of lung and spleen qi, loss of solid defense and evil invasion of the nutritive and defensive levels; qi deficiency and depression lead to heat damage to yin, while long-term blood damage to collaterals involves yang. The pathological process shows the changes from qi entering blood and from meridian to collateral, which eventually leads to the imbalance of qi and blood, yin and yang, the stagnation of phlegm and blood stasis, the obstruction of lung collateral, the mixture of excess and deficiency, and the lingering is difficult to heal. In the treatment, the "spleen is the envoy" is the center, the lung and spleen are treated together, the qi of lung and spleen is strengthened, the yin of lung and stomach is nourished, and finally the root is protected. The treatment is based on syndrome differentiation, modified with syndromes, and the methods of promoting blood circulation, resolving phlegm, warming yang and dredging collaterals are supplemented in time, which provides a new idea for enriching the differentiation and treatment of IPF in TCM.

Objective:To predict the Ki-67 expression grading in patients with mass breast cancer based on multimodal ultrasound features to aid clinical diagnosis and treatment.Methods:Ninety-three female patients (93 masses in total) with breast cancers confirmed by pathological examination were retrospectively included in the Second Affiliated Hospital of Harbin Medical University from September 2017 to September 2020. According to the immunohistochemical results, the patients were divided into Ki-67 high expression group (55 cases) and Ki-67 low expression group (38 cases). The qualitative and quantitative features from two-dimensional gray-scale ultrasound, color Doppler flow imaging (CDFI), shear wave elastography (SWE) and contrast-enhanced ultrasound (CEUS) images of all breast masses were retrospectively analyzed, differential features were analyzed based on logistic regression algorithm. ROC curves and Kappa test were used for the evaluation of diagnosis.Results:The univariate analysis revealed statistically significant differences between the two groups for conventional ultrasound features (size, shape, margins), SWE features (stiff rim sign, Eratio), and CEUS features (perfusion defect, IMAX) (all P<0.05). In the multiple logistic regression analysis, the margins, stiff rim sign, and perfusion defect were the independent factors for predicting the Ki-67 expression (all P<0.05). The performance of the predictive model was 0.882 (95%confidence interval of 0.798-0.940, P<0.05) with the sensitivity of 0.818 and specificity of 0.790. Conclusions:A preliminary analysis of the relationship between multi-modal ultrasound features and Ki-67 expression grading in mass breast cancers was performed based on logistic regression algorithm to provide more imaging information for clinical treatment and prognosis assessment.

Objective:To investigate whether ultrasound features, mammographic features and immunohistochemical indicators show any association with rates of axillary pathologic complete response(pCR) in cN 1 breast cancer patients receiving neoadjuvant chemotherapy(NAC), and to construct prediction models of axillary pCR to predict axillary lymph nodes (ALN) status, so as to select suitable patients for less invasive axillary surgery after NAC. Methods:This retrospective study evaluated 134 consecutive cN 1 breast cancer patients with ALN metastasis who underwent NAC in the Second Affiliated Hospital and Tumor Hospital of Harbin Medical University from July 2020 to July 2022. According to the pathological results of ALN surgery after NAC, the cases were divided into pCR and non pathologic complete respose(npCR) groups. The ultrasound images, mammographic images and immunohistochemical indicators of the two groups were compared. In terms of logistic regression algorithm, the model A(the ultrasound model), the model B(the ultrasound combined with mammography model), the model C(the ultrasound combined with immunohistochemistry model) and the model D(the ultrasound combined with mammography and immunohistochemistry model) were respectively established for predicting the pathological state of axillary lymph nodes in breast cancer patients, ROC curves were plotted to evaluate the performance of the models, and the diagnostic efficiency of different models was compared by Delong′s test. The model with the best predictive performance was shown in a nomogram. Results:①The P values between two groups of the short diameter of ALN, the ratio of long/short diameter of ALN, fatty hilum and central hilar vascularity, mammographic spiculation, estrogen receptor(ER), progesterone receptor(PR), human epidermal growth factor receptor 2(HER2) were <0.05 by the t test and χ 2 test analysis. ②The ratio of long/short diameter and fatty hilum in the model A were independent factors for predicting the pathological status of ALN after NAC. The independent predictors of model B and Model C were respectively added with mammographic spiculation and immunohistochemical indicators (ER, PR) on the basis of model A. In the model D, the ratio of long/short diameter, short diameter, fatty hilum, mammographic spiculation, and immunohistochemical indicators (ER, PR) remained significant independent predictors associated with axillary pCR. ③The area under ROC curve (AUC) of the model A, B, C, D was 0.78, 0.84, 0.84 and 0.89, respectively. The sensitivity was 0.71, 0.80, 0.78 and 0.86, the specificity was 0.76, 0.74, 0.76 and 0.80, and the accuracy was 0.73, 0.76, 0.77 and 0.83, respectively. ④Delong′s test showed the model D had an improved AUC of 0.89(0.89 vs 0.78, 0.84, 0.84, all P<0.05). Conclusions:The prediction models combining bi-modal imaging and immunohistochemical indicators show good prediction ability and can provide reference for selecting suitable patients for less invasive axillary surgery after NAC.

Objective:To summarize the clinical features, viral load changes, and outcomes of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Omicron variant infection in mother-infant dyads during lactation period.Methods:A total of 24 pairs of lactating mothers and infants under one year old who were infected with SARS-CoV-2 and hospitalized in Lingang Branch of Shanghai Sixth People's Hospital from April 8 to May 30, 2022, were selected as the lactation group in this retrospective study. Another 24 non-lactating mothers, with children of one to three years old, who matched with those mothers in the lactation group in clinical classification and admission date were selected as the control group. Vaccination status, clinical symptoms, daily cycle threshold (Ct) of open reading frame 1ab ( ORF1ab) gene and nucleocapsid protein ( N) gene, and the duration of positive nucleic acid test were compared between the groups and were analyzed using two independent samples t test, one-way analysis of variance, LSD test, and Chi-square test. Results:Among the 24 infants in the lactation group with an age of (6.5±2.1) months, 23 cases were mild type, one was common, and none had been vaccinated against SARS-CoV-2. The maternal age of the lactation and the control group did not differ statistically [(28.7±6.4) vs (28.2±5.2) years, t=0.30, P=0.768]. Mothers with mild type accounted for 88% (21/24) and those with common for 12% (3/24) in both groups of mothers. Three mothers received one dose of vaccine and two received two in the lactation group, while three received one dose and three received two in the control group [21%(5/24) vs 25%(6/24), χ 2=0.12, P=0.731]. The most common symptoms of lactating infants were fever (100%, 24/24) , followed by diarrhea (58%, 14/24) , cough (50%, 12/24), and wheeze (29%, 7/24), those of the lactating mothers were fever (75%, 18/24) , cough (75%, 18/24) , and sore throat (63%, 15/24) , while those of non-lactating mothers were cough (88%, 21/24) , sore throat (71%, 17/24), and fever (58%, 14/24). The duration of positive nucleic acid test was the shortest in the lactating infants [(9.2±2.1) d (5-14 d)], followed by mothers in the control group [(11.2±2.4) d (6-16 d)] and mothers in the lactation group [(14.0±4.2) d (8-26 d)] (LSD test, all P<0.05). Each day from day 2 to 9 after diagnosis, Ct values of nucleic acid of infants in the lactation group were all higher than those of mothers in both the lactation and control groups (LSD test, all P<0.05). On day 10, Ct value of nucleic acid infants was higher than that in mothers in the lactation group ( ORF1ab gene: 37.91±4.34 vs 32.79±5.47; N gene: 37.95±4.58 vs 32.66±5.77), which was lower than those in mothers in the control group ( ORF1ab gene: 32.79±5.47 vs 35.90±4.17; N gene: 32.66±5.77 vs 36.08±4.16) (LSD test, all P<0.05). On day 11, the nucleic acid Ct values of mothers in the lactation group were all lower than those in the control group ( ORF1ab gene: 35.03±3.74 vs 37.84±3.26, t=－2.78, P=0.008; N gene: 35.30±3.75 vs 38.11±2.90, t=－2.90, P=0.006). On day 12, Ct value of ORF1ab gene and N gene in mothers in the lactation group were similar to those in mothers in the control group (both P>0.05). Conclusions:The SARS-CoV-2 vaccination rate of mothers and infants were low during lactation. Lactating infants infected with SARS-CoV-2 Omicron variant have low virus load and may have a quick recovery, while for the lactating mothers, the virus load is high and the recovery is slow.

Objective: To evaluate the effect of online lifestyle intervention based on cognitive behavior adjustment on the female patients with infertility and central obesity. Methods: From November 2019 to November 2020, the women with infertility and central obesity in the Reproductive Medicine Center of Zhejiang Provincial People's Hospital were recruited and divided into two groups. The intervention group received online lifestyle intervention based on cognitive behavior adjustment for twelve weeks, and the control group received routine health education. Body weight, waist circumference, fasting blood glucose, fasting insulin, insulin resistance index (HOMA-IR), body fat, the pregnancy rate and the abortion rate were compared between the two groups. Results: There were 78 cases each in the intervention group and the control group, aged (31.15±4.87) years and (31.17±4.81) years, respectively. There were no significant differences between the two groups in age, body weight, body mass index, waist circumference, waist-hip ratio, fasting blood glucose, fasting insulin, HOMA-IR and body fat percentage before intervention (all P>0.05). After twelve-week intervention, the results of mixed effect model showed that the decrease of waist circumference, fasting insulin and body fat percentage in the intervention group were greater than those in the control group (all P<0.05). After six-month follow-up, there was no significant differences in the pregnancy rate (33.33% vs. 23.08%) and the abortion rate (7.69% vs. 16.67%) between the two groups (both P>0.05). Conclusion Online lifestyle intervention based on cognitive behavior adjustment helps to control central obesity and hyperinsulinemia.

Objective:To investigate the effect of virtual reality (VR) video-based pre-discharge psychological intervention on the post-discharge emotions of patients with deep facial burn.Methods:From October 2017 to September 2019, 84 patients with deep facial burn who were hospitalized in the First Hospital of Jilin University and met the inclusion criteria were enrolled in the prospective randomized controlled study were. According to the random number table, the patients were divided into two groups, with 40 cases (21 males and 19 females) left in VR video group, aged 18-53 years and 41 cases (22 males and 19 females) in general video group, aged 19-55 years after several patients dropped out in follow-up. Seven patients who had been treated in the First Hospital of Jilin University from January 2014 to December 2016 and returned to work and life after recovering from the deep facial burn were selected, and then the pictures and corresponding commentaries before and after burn injuries, the problems and solutions after discharge, and the image data of living status of each patient were edited and recorded into a video. From seven days before discharge, the patients in VR video group began to watch videos by wearing VR glasses, while the patients in general video group began to watch videos on a tablet computer, for 7 days . On the 7th day before discharge (before watching the videos) and one month after discharge, the Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and Social Avoidance and Distress (SAD) Scale were used to evaluate the level of anxiety, depression, and social avoidance and distress of patients in both groups. Data were statistically analyzed with paired or independent sample t test, chi-square test, or Fisher′s exact probability test. Results:On the 7th day before discharge, the scores of anxiety, depression, and social avoidance and distress of patients in general video group were (34±7), (34±6), and (11.5±3.9) points, respectively, close to (35±7), (35±5), and (10.5±3.9) points in VR video group ( t=-0.803, -1.050, 1.122, P>0.05), and the scores of both groups were higher than the national norms. One month after discharge, the scores of anxiety, depression, and social avoidance and distress of patients in VR video group were (31±5), (31±5), and (7.2±2.5) points, respectively, significantly lower than the scores on the 7th day before discharge ( t=6.609, 7.492, 7.622, P<0.01); the scores of anxiety, depression, and social avoidance and distress of patients in general video group were (37±7), (38±8), and (13.9±7.4) points, respectively, significantly higher than the scores on the 7th day before discharge ( t=2.802, 3.599, 2.739, P<0.01). One month after discharge, the scores of anxiety, depression, and social avoidance and distress of patients in VR video group were significantly lower than those in general video group ( t=4.722, 5.043, 5.490, P<0.01). Conclusions:Pre-discharge psychological intervention of patients with deep facial burn using VR videos can alleviate their bad emotions after discharge, such as anxiety, depression, and social avoidance and distress.
