Intra- and extrauterine treatment for giant fetal axilla-thoracic cystic lymphangioma: a case report / 中华围产医学杂志

Fetal cystic lymphangioma is a developmental anomaly of the lymphatic system, which can occur in any part of the body, but most commonly in the neck and armpit. A case of fetal cystic lymphangioma located at the chest wall under the right armpit with a size of 21 mm×18 mm×16 mm is reported here. The mass was initially diagnosed by routine ultrasound examination at 21 gestational weeks. After the diagnosis, ultrasound was repeated every 4 weeks till 37 +4 gestational weeks. Over this period, the mass increased progressively to 101 mm×110 mm×95 mm. Ultrasound-guided intrauterine fetal cystic mass puncture and aspiration was performed 38 +4 weekss, and Bleomycin was injected into the cyst after operation and on day 42 after birth. During a follow-up to 10 months after birth, no obvious cystic mass was found at the right axillary chest wall of the child.

Pingyangmycin sclerotherapy for early-stage peripheral arteriovenous malformations / 中华整形外科杂志

Objective@#To investigate the safety and efficacy of pingyangmycin (bleomycin A5) sclerotherapy for early peripheral arteriovenous malformations (AVM).@*Methods@#Thirteen cases of early-stage [Schobinger clinical stage (Ⅰ/Ⅱ)] peripheral AVM patients (11 stage Ⅰ and 2 stage Ⅱ patients) aged between 3 months and 51 years were selected between January 2012 and May 2015. Pingyangmycin sclerotherapy injections were administered with B-scan ultrasonography or digital subtraction angiography positioning. All patients underwent relevant supplementary examinations before and after the procedure, and clinical evaluation was performed based on the improvement of the clinical symptoms of the patient and re-examination of lesion by imaging.@*Results@#A total of 88 injections were administered to the 13 patients with an average of 6.7 injections per patient, 3-6 years of follow-up. Based on clinical evaluation, 7 patients were generally cured, 3 patients had significant improvement, 2 patients had partial improvement, and 1 patient had no improvement. Seven patients had different levels of postoperative swelling that resolved on its own. No serious complications occurred.@*Conclusions@#Pingyangmycin sclerotherapy for treatment of early peripheral AVM was effective and had few complications. It can control further progression of pathological changes.

Effects of chronic arsenic exposure on energy metabolism in human keratinocytes / 中华地方病学杂志

Objective To explore the effects of chronic sodium arsenic (NaAsO2) exposure on energy metabolism in human keratinocytes (HaCaT).Methods Malignant transformation was induced when HaCaT cells were continuously exposed to an environmentally relevant level (0.1 μ mol/L) of inorganic arsenic for 28 weeks,HaCaT and malignantly transformed cells were kept in Group of Chronic Disease and Environmental Genomics,School of Public Health,China Medical University.Basal oxygen consumption rate and extracellular acidification rate in control group and malignantly transformed group were measured by Agilent Seahorse XF24.Changes of glucose intake in malignantly transformed HaCaT cells were detected by 2-NBDG.Cells in logarithmic growth phase were collect,mRNA levels of key components in glycolytic pathwa [glucose-6-phosphate dehydrogenase (G6PD),phosphofructokinase (PFKL),glyceraldehyde-3-phosphate dehydrogenase (GAPDH)] and mitochondrial respiratory chain complex [NADH dehydrogenase iron-sulfur protein subunit 3 (NDUFS3),succinate dehydrogenase iron-sulfoprotein subunit (SDHB),cytochrome C (CYTC),CYTC oxidase subunit Ⅳ (COX4L1),ATP synthase F1 subunit (ATP5B),and ATP synthase F0 subunit (ATP5G1)] were determined by real-time quantitative PCR (RT-qPCR).Results The basal oxygen consumption rate of malignantly transformed group [(44.784 ± 10.159) pMoles/min] was lower than that of control group [(66.842 ± 15.756) pMoles/min,t =4.914,P ＜ 0.05].The glucose intakes of malignantly transformed group (1.592 ± 0.410 for cells cultured without serum,and 1.631 ± 0.323 for cells cultured with serum) were significantly higher than those of control group (1.000 ± 0.334,1.000 ± 0.196,t =2.916,4.068,P ＜0.05).The mRNA levels of G6PD (0.555 ± 0.009),NDUFS3 (0.623 ± 0.031) and SDHB (0.702 ± 0.094)in malignantly transformed group were significantly lower than those of control group (1.000 ± 0.027,1.000 ±0.034,1.000 ± 0.114,t =23.690,11.340,2.814,P ＜ 0.05);the mRNA levels of PFKL (1.787 ± 0.176),GAPDH (1.466 ± 0.111),CYTC (2.461 ± 0.179),ATP5B (1.956 ± 0.161),and ATP5G1 (2.055 ± 0.052) were significantly higher than those of control group(1.000 ± 0.153,1.000 ± 0.069,1.000 ± 0.030,1.000 ± 0.091,1.000 ± 0.237,t =4.696,4.985,11.540,7.436,6.021,P ＜ 0.05).Conclusion When continuously exposed to an environmentally relevant level of inorganic arsenic,the glucose metabolic pattern of HaCaT cells is changed along with lower oxygen consumption and higher glycolysis levels.

Diagnostic value of virtual tissue quantification in differentiating benign or malignant of breast tumors / 中国医师杂志

Objective To investigate the value of acoustic radiation force impulse (ARFI) in differential diagnosis between benign and malignant breast tumors.Methods Virtual touch tissue imaging (VTI) and virtual touch tissue quantification (VTQ) of ARFI elastography were used to estimate the properties and extent and measured the shear wave velocities (SWV) of the breast tumors,respectively.Results The mean SWV of breast cancer and benign lesion were (7.84 ±2.51)m/s and (2.79 ±0.92)m/s.There was significant difference in the SWV between benign and malignant breast tumors (P ＜ 0.01).The area under curve (AUC) of receiver operating characteristic (ROC) curve of the SWV in differentiating benign from malignant breast tumors was 0.886.With SWV 4.4 as cut-off,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value in the diagnosis of malignant from benign breast tumors were 78.7％,100％,91.7％,100％,88％,respectively.Conclusions ARFI elastography could reflect the elastic characteristics of breast tumors,which might be useful for the differential diagnosis between benign and malignant breast tumors.
