Objective:To investigate the clinical outcomes and prognosis of children who were prenatally diagnosed with solid space-occupying abdominal lesions by ultrasound.Methods:This study retrospectively enrolled 30 children with solid space-occupying abdominal lesions that were indicated by prenatal ultrasound at Children's Hospital of Fudan University from March 2015 to March 2021. Prenatal ultrasound findings, postnatal treatment, clinical outcomes, and prognosis were analyzed.Results:These subjects included 18 male and 12 female infants, with the median gestational age at the first sonographic diagnosis of 36 weeks (28 to 39 weeks). The intra-abdominal solid masses were postnatally confirmed to be located in liver, retroperitoneum, and gastrointestinal tract, which were hepatic hemangioma ( n=14), hepatoblastoma ( n=2), neuroblastoma ( n=6), abdominal teratoma ( n=4), adrenal hematoma ( n=1), adrenocortical adenoma ( n=1), hyperplasia of renal capillary ( n=1), and gastrointestinal teratoma ( n=1). The accuracy of prenatal ultrasound in detecting the location of masses was 73% (22/30) and which was 13/16 in detecting masses from liver and 9/14 in that outside the liver. Among the 30 cases, 73% (22/30) were benign tumors, and 27% (8/30) were malignant tumors (hepatoblastoma in two cases and neuroblastoma in six cases). Among 15 patients with benign tumors (hepatic hemangioma and adrenal hematoma) who received close follow-up or drug therapy, tumor/lesion regression occurred in 13 cases and the other two were observed with stable hepatic hemangiomas. Fourteen patients, including six with neuroblastoma, two with hepatoblastoma, five with teratoma, one with adrenocortical adenoma, and one with hyperplasia of renal capillary, had good prognosis after primary tumor resection or combined with postoperative chemotherapy. One hepatoblastoma case died after withdrawing treatment. The overall survival rate was 97% (29/30) with a median follow-up time of 24 months (4 to 60 months). Conclusions:Prenatal ultrasound has high accuracy in identifying the anatomic region of fetal solid space-occupying abdominal lesions. With close postnatal follow-up and proper treatment, most of the affected fetuses will have a good outcome and prognosis.

Objective: To summarize the clinical characteristics of patients with Takotsubo syndrome (TTS) from China and compare these features with patients from Europe/North America. Methods: We reviewed case reports published between 1990 and 2020 with the key words of "Takotsubo syndrome" "stress cardiomyopathy" "apical balloon syndrome" and "broken heart syndrome", in Wanfang, CNKI, Pubmed and Web of Science databases, and 1 294 articles were identified, including 128 articles reporting 163 cases in China and 1 166 articles reporting 1 256 cases in Europe/North America. The characteristics of demographics, triggers, symptoms, electrocardiogram, echocardiography, left ventriculogram,coronary angiography, treatment and prognosis were analyzed and compared between Chinese and European/North American cases. Results: A total of 1 294 articles (1 419 cases: 163 from China, 1 256 from Europe/North America) were included in the final analysis. The characteristics of Chinese cases included: (1) demographic:the age was (59.6±16.9) years, which was similar with that of European/North American ((59.7±17.4) years, P=0.90), and female accounting for 78.5% (128/163), which was lower than that of European/North American (85.4% (1 073/1 256), P=0.02). (2) Triggers:mental triggers accounted for 48.5% (79/163), physical triggers accounted for 43.6% (71/163), and no triggers accounted for 7.9% (13/163), respectively. Compared with Europe/North America, the ratio of patients with mental triggers was higher in China, while the ratio of patients with physical triggers and no triggers was lower (P<0.05).

Objective:To analyse the pathogenic bacteria distribution and clinical characteristics of late-onset sepsis (LOS) among premature infants with gestational age less than 34 weeks in Henan Province.Methods:The clinical data of 6 590 premature infants admitted to 17 medical institutions in Henan Province from January 2019 to December 2020 were retrospectively analyzed. The gestational age of infants was less than 34 weeks and was admitted to the neonatal ward within 7 days after birth. SPSS 19.0 statistical software was used for data analysis.Results:Among 6 590 premature infants LOS developed in 751 cases (11.40%), of whom the diagnosis was confirmed in 276 cases (36.75%) and 475 cases (63.25%) were diagnosed clinically. The fatality rate related to LOS was 13.58%. There were significant differences in the incidence of LOS and infection-related mortality among infants with different gestational ages and body weights ( χ2=388.894 and 13.572, χ2=472.282 and 9.257, P<0.05 or <0.01). Among 276 children with confirmed LOS, 286 strains of pathogenic bacteria were isolated. Gram-negative bacteria were most prevalent (178 strains), accounting for 62.24% of all infections, followed by fungi (58 strains, 20.28%). Klebsiella pneumoniae was most frequently detected Gram-negative bacteria (117 strains, 40.91%), among which 32.48% (38/117) was carbapenem-resistant Klebsiella pneumoniae. The proportion of diagnosed sepsis, the proportion of catheterization, and the infection-related mortality of infants with LOS in tertiary hospitals were all higher than those in secondary hospitals ( χ2=6.212, 5.313 and 4.435, all P<0.05). The proportion of exclusive breastfeeding in secondary hospitals was lower than that in tertiary hospitals ( χ2=19.216, P<0.05). The time of antibacterial drug use before infection in specialized hospitals was longer than that in general hospitals ( χ2=3.276, P<0.05). Conclusion:The incidence of LOS among preterm infants in Henan Province is high, which was mainly caused by Gram-negative bacteria. The clinical characteristics of LOS caused by different pathogens and in different health institutions are different, the prevention and control strategy should be developed accordingly to reduce the incidence LOS of preterm premature infants.

Objective:To explore the mechanism of potassium iodide-induced pyrolysis of thyroid follicular cells.Methods:Thyroid gland tissue was obtained from patients with thyroid cancer (TC) coexisting with Hashimoto′s thyroiditis, and the tumor-adjacent Hashimoto′s thyroiditis tissue was used as the control. ELISA was used to detect the concentration of the pyroptosis inflammatory cytokines interleukin (IL)-1β and IL-18 in the tissues, and Western blotting was used to detect the activation of gasdermin (GSDM) proteins, a biomarker for pyroptosis. Thyroid follicular cells treated with different concentrations of potassium iodide, and IL-1β, IL-18, lactate dehydrogenase (LDH), GSDMD were measured. Transcriptome chip analysis was used to explore the differentially expressed genes involved in pyroptosis of thyroid follicular cells induced by potassium iodide treatment.Results:The levels of IL-1β and IL-18 cytokines in the tissues of patients with Hashimoto′s thyroiditis and thyroid cancer were higher than control tissues ( P<0.01), and the activation of the pyroptosis executive protein GSDMD was significant increased, while GSDME was not activated. IL-1β, IL-18, and LDH secretion were significantly increased in response to potassium iodide stimulation in thyroid follicular cells ( P<0.01) and GSDMD was cleaved, which indicated that potassium iodide induced the pyroptosis of thyroid follicular cells. Moreover, potassium iodide could activate NLRP3 inflammasomes to promotethe pyroptosis of thyroid follicular cells. Transcriptome chip analysis further found that PARP1 protein was highly upregulated by the stimulation of potassium iodide, and then enhanced the activity of nuclear factor-κB (NF-κB) transcription factor to induce pyroptosis. Conclusions:The findings in this study reveal that potassium iodide promotesthe pyroptosis of thyroid follicular cells through activating NF-κB-NLRP3 inflammasome, which may be a novel mechanism that promots the development of Hashimoto′s thyroiditis under the condition of excessive iodine intake. PARP1 is a pivotal protein that mediates the pyroptosis induced by potassium iodide and may be a potential therapeutic target to control Hashimoto′s thyroiditis progression.

Objective To quantitatively compare the effect of preservation or removal of atlas posterior arch on cervical posterior decompression,so as to provide a basis for reasonable selection of upper cervical spine decompression range and determination of surgical indications for atlas posterior arch resection.Methods The data of 45 patients with posterior decompression of upper cervical spine were retrospectively analyzed.According to the decompression range,the patients were divided into C2-C7 group and C1-C7 group.There were 25 cases in the C2-C7 group,19 males and 6 females,with an average age of 56.3 years (40-71 years),4 cases of cervical spondylotic myelopathy and 21 cases of ossification of the posterior longitudinal ligament of cervical spine.All of the 25 patients underwent open-door laminoplasty:20 cases with hinge side anchoring procedure and 5 cases with preservation of the unilateral posterior muscular-ligament complex procedure (titanium cable procedure).There were 20 cases in C1-C7 group,12 males and 8 females,with an average age of 58A years (44-75 years).All of the 20 cases underwent atlas posterior arch resection as well as C2-C7 open-door laminoplasty,including anchoring procedure in 1 case,titanium miniplate procedure in 4 cases,and titanium cable procedure in 15 cases.Standardized vertebral-cord distance (SVCD) at each level from atlas to level C~ was measured on T2-weighted images of MR on the mid-sagittal plane in the neutral position pedormed 3-12 months postoperatively at each individual level.As the main outcomes,the SVCD values obtained at the same level of the two groups were compared between the two groups.Shapiro-Wilk normality test was performed on the SVCD values at C1.2 and C2 levels of two groups.The area under the normal distribution curve of SVCDs was used to calculate the corresponding residual compression rate with different magnitude of compression mass to further discover the difference of the decompression effect between the two groups.Results The SVCD obtained at the level of the anterior arch of atlas (C1),the junction of odontoid process and axis (C1,2) and the middle part of axis body (C2) in the C2-C7 group was 9.91±1.34 mm,8.35±1.27 mm,and 8.22 ±1.43 mm,respectively.The SVCD at the same levels was 11.02±1.60 mm,9.72±1.24 mm,and 9.12±1.11 mm,respectively.SVCDs differed significantly in the above range between the two groups.However,from level C2,3 to C6,7,there was no significant difference in SVCDs between the two groups.The JOA score of group C2-C7 was 11.8±2.7 preoperatively and increased significantly to 14.7±1.8 at 12 months postoperatively(t=-7.006,P＜0.001) with a recovery rate of 57.0％±32.2％.The JOA score of group C1-C7 was 11.7±2.8 preoperatively and increased significantly to 14.2±2.3 at 12 months postoperatively(t=-6.177,P＜0.001) with a recovery rate of 51.9％±32.1％.Conclusion Atlas posterior arch resection can significantly increase the decompression effect of posterior cervical surgery from the anterior arch of atlas to the middle part of axis body,but it would not increase the decompression effect at level C2.3 or below.When the magnitude of the ventral compression factor exceeds the decompression limit (8.5 mm) available with C2-C7 decompression in the range from atlas to the middle of the axis body,extending the decompression range by atlas posterior arch resection is an effective means to achieve adequate decompression.
