RESUMEN
Objective To summarize the effect of the timing of lung transplantation and related treatment measures on clinical prognosis of patients with paraquat poisoning. Methods Clinical data of a patient with paraquat poisoning undergoing bilateral lung transplantation were retrospectively analyzed. Clinical manifestations, auxiliary examination, diagnosis and treatment of this patient were summarized and analyzed. Results A 17-year-old adolescent was admitted to hospital due to nausea, vomiting, cough and systemic fatigue after oral intake of 20-30 mL of 25% paraquat. After symptomatic support treatment, the oxygen saturation was not improved, and pulmonary fibrosis continued to progress. Therefore, sequential bilateral lung transplantation was performed under extracorporeal membrane oxygenation (ECMO). After postoperative rehabilitation and active prevention and treatment for postoperative complications, the patient was discharged at postoperative 50 d. Conclusions The timing of lung transplantation after paraquat poisoning may be selected when the liver and kidney function start to recover. Active and targeted prevention of potential pathogen infection in perioperative period and early rehabilitation training contribute to improving clinical prognosis of lung transplant recipients.
RESUMEN
Placenta accreta spectrum (PAS) disorders are one of the important causes of adverse pregnancy outcomes. Some studies reported that the limitations in commonly used auxiliary examination methods led to missed or misdiagnosis, resulting in adverse pregnancy outcomes. Digital three-dimensional (3D) reconstruction is the 3D graphical visualization constructed on the original data to illustrate the spatial relationship between structures, overcoming the limitations of two-dimensional images. As a novel auxiliary diagnostic tool, digital 3D reconstruction provides promising insights into the development of personalized precision medicine. This article reviews the research and application of ultrasound and MRI 3D reconstruction in the field of PAS.
RESUMEN
Objective:To investigate the characteristics related to proliferation, migration and invasion of radiation-induced polyploid colon cancer SW1116 cells and their progeny.Methods:Colon cancer SW1116 cells were conventionally cultured in Leibovitz's L-15 medium containing 10% fetal bovine serum. SW1116 cells at logarithmic growth stage were irradiated with 7 Gy X-ray, and the morphological changes of the cells were observed by inverted microscope on days 3, 5, 10 and 19 after radiation induction. According to the morphological changes of the cells, the cells at day 3 after radiation induction were labeled as polyploid giant cancer cell (PGCC) group, and the cells at day 19 were recorded as PGCC progeny group. SW1116 cells without radiation induction were used as control group. Flow cytometry was used to detect cell ploidy in the control, PGCC and PGCC progeny groups, CCK-8 assay was used to detect the proliferation ability of the three groups, cell migration and invasion abilities of the three groups were detected by cell scratch assay and Transwell assay, and Western blotting was used to detect the expressions of cell cycle and proliferation-related proteins and epithelial-mesenchymal transition (EMT) marker N-cadherin (N-cad) in the three groups.Results:The volume of SW1116 cells gradually became larger on days 3, 5 and 10 after radiation induction, and returned to normal on day 19. The proportions of polyploid (DNA content >4N) cell subsets in the control group, PGCC group and PGCC progeny group were (2.3±1.1)%, (23.1±8.1)% and (3.2±0.5)%, the difference was statistically significant ( F = 18.52, P < 0.05), and the proportion of polyploid cell subpopulations in the PGCC group was higher than that in the control group ( t = 5.38, P < 0.01), but the differences between the PGCC progeny group and the control group were not statistically significant ( t = 0.22, P > 0.05). After 72 h of culture, the cell proliferation rates of the control, PGCC and PGCC progeny groups were (100.0±4.1)%, (73.5±0.7)% and (123.9±3.5)%, and the difference was statistically significant ( F = 190.27, P < 0.001). After 48 h of cell scratching, the scratch healing rates in the control, PGCC and PGCC progeny groups were (38.0±2.7)%, (41.5±4.0)% and (63.7±4.2)%, and the difference was statistically significant ( F = 43.05, P < 0.001). After 24 h of culture, the number of invasive cells in the control, PGCC and PGCC progeny groups was 12.9±1.2, 3.4±0.6 and 23.7±1.5, and the difference was statistically significant ( F = 63.64, P < 0.001). The expression levels of cell cycle-related proteins P-cdc25c, cdc25c and cdc2 in the PGCC group were lower than those in the control group (all P < 0.05), and the expression levels of transcription factor-related proteins E2F-2, E2F-3 and EMT marker N-cad were downregulated compared with the control group (all P < 0.05); the expression levels of P-cdc25c, cdc25c, cdc2, E2F-2, E2F-3 and N-cad proteins in the PGCC progeny group were higher than those in the control group (all P < 0.05). Conclusions:Radiation can induce colon cancer SW1116 cells to produce polyploid, which may then generate daughter cells through asymmetric mitosis and gain new life, and then promote the recurrence and metastasis of colon cancer.

Objective:To investigate the biological characteristics of proliferation, apoptosis, migration and invasion of radiation-induced polyploid cervical cancer HeLa cells, and to analyze the potential facilitation of polyploid HeLa cells in cervical cancer recurrence after radiotherapy.Methods:HeLa cells were irradiated by 6 MV-X ray with 7 Gy and 14 Gy, the cells were cultured until the third day, and then they were recorded as 7 Gy group and 14 Gy group respectively. The unirradiated HeLa cells were recognized as the control group. The cell morphology was checked under optical microscope. Flow cytometry was used to determine cell ploidy. MTT assay was applied to detect cell proliferation. Flow cytometry by AnnexinⅤ-FITC/PI double labeling was used to detect apoptosis. The ability of migration and invasion was detected by Transwell assay. The expression levels of STAT3 signal pathway-related proteins were analyzed by Western blotting.Results:Compared with the control group, the volume of HeLa cells in 7 Gy group and 14 Gy group increased significantly. The percentages of polyploid HeLa cell subsets in the control group, 7 Gy group and 14 Gy group were (6.33±1.26) %, (21.13±0.50) % and (46.07±1.68) % respectively, with a statistically significant difference ( F=780.47, P<0.001) . The absorbance values in the control group, 7 Gy group and 14 Gy group of polyploidy HeLa cells were 0.21±0.01, 0.23±0.02, 0.16±0.01 at 24 h, 0.37±0.03, 0.38±0.06, 0.21±0.00 at 48 h, 0.66±0.02, 0.55±0.01, 0.28±0.01 at 72 h, and there were statistically significant differences ( F=31.62, P=0.001; F=20.10, P=0.002; F=708.52, P<0.001) . Further pairwise comparison showed that the proliferation abilities of polyploidy HeLa cells of the 14 Gy group at 24, 48 and 72 h were significantly lower than those of the control group and the 7 Gy group (all P<0.05) . The proportions of apoptotic cell subset in the control group, 7 Gy group and 14 Gy group were (3.67±1.16) %, (3.07±0.81) %, (3.83±0.91) %, the proportions of early apoptotic subset were (2.33±0.35) %, (2.13±0.61) %, (2.23±0.32) %, and the proportions of late apoptotic subset were (1.33±0.81) %, (0.93±0.31) %, (1.60±0.60) % respectively. There were no statistically significant differences ( F=0.52, P=0.620; F=0.15, P=0.864; F=0.92, P=0.450) . The migrated numbers of cells in the control group, 7 Gy group and 14 Gy group were 297.40±26.53, 121.33±15.16, 18.40±4.79, and the invaded numbers were 195.67±20.26, 63.60±6.91, 9.47±3.23 respectively, with statistically significant differences ( F=647.28, P<0.001; F=213.94, P<0.001) . Compared with the control group, the migration and invasion abilities of polyploid HeLa cells in the 7 Gy and the 14 Gy groups were significantly decreased, and the migration and invasion abilities of polyploid HeLa cells in the 14 Gy group were significantly lower than those in the 7 Gy group (all P<0.001) . The expression levels of P-STAT3 (Tyr 705) and Bcl-2 in radiation-induced polyploidy HeLa cells were higher than those in the control group, and the expression levels were further increased with the increase of radiation dose. Compared with the control group, the expression levels of Survivin and Mcl-1 in polyploid HeLa cells in the 14 Gy group were up-regulated (both P<0.05) . There was no significant difference in Bcl-xL expression among the three groups ( F=0.52, P=0.618) . Conclusion:The proliferation, migration and invasion abilities of polyploid HeLa cells are reduced by radiation, and the proportion of apoptotic subset is not significantly changed, but the activation of STAT3 signaling pathway is accompanied by up-regulation of downstream anti-apoptotic related proteins, which is favorable for the polyploid tumor cells to be the potential risk factor of recurrent cervical cancer after radiotherapy.

RESUMEN
Objective To explore the clinical significance of non-invasive prenatal genetic testing to screen prenatal fetal chromosomal abnormalities. Methods Peripheral blood was collected from 6 283 pregnant women who underwent non-invasive prenatal genetic testing at our hospital, and fetal DNA was extracted and purified for analysis. The complementary base principle of semiconductor chip technology was used to analyze all sequenced signals with BioelectronSeq 4000. Invasive prenatal diagnosis was performed in high-risk pregnant women according to the results of the sex chromosome sequencing signal analysis. Results Of the 6 283 pregnant women screened, 14 were found to have chromosomal abnormalities, and the positive rate was 0. 22%. Karyotype analysis was performed on 11 of the women; the remaining 3 refused to be diagnosed. Of these 11 women, 2 of the 5 patients with a high risk of XO were diagnosed with fetal chromosomal abnormalities (diagnosed as XO/XXX chimera and XO, respectively), and 3 were diagnosed with a normal karyotype; 5 patients with a high risk of XXY were diagnosed as XXY; and 1 patient with a high risk of XXX was confirmed as XXX. NIPT accuracy was measured to be 73% (8/11). The detection rate of fetal chromosomal abnormalities by non-invasive prenatal genetic testing was significantly higher in the years 2015-2016 than in 2011-2014 (P < 0. 05). Conclusion Non-invasive prenatal genetic testing for screening chromosomal abnormalities has a high accuracy rate and could improve the detection rate of fetal chromosomal abnormalities.
RESUMEN
Objective To investigate the effect of triptolide (TP) on proliferation and apoptosis of cyst-lining epithelial cells with autosomal dominant polycystic kidney disease ( ADPKD). Methods Primary cultured cyst-lining epithelial cells were treated with TP at different concentrations for 12 h,24 h,48 h and 72 h, respectively.The proliferation activity of the cells was evaluated by Brdu assay. The cell cycle distribution was determined by flow cytometry. The apoptotic and apoptotic ratio were determined by FITC-AnnexinV binding/ PI. The morphological changes of cyst-lining epithelial cells were observed under transmission electron microscope. Results TP significantly inhibited the proliferation of cyst-lining epithelial cells and induced apoptosis in a dose- (10-40 ng?mL-1 )and time-dependent(12-48 h) manner. Typical ultrastructural changes of apoptotic cells were observed under electron microscope. Conclusion TP significantly inhibited the proliferation of cyst-lining epithelial cells and induced the apoptosis of cyst-lining epithelial cells, thus inhibited cyst forming and delayed cyst developing. The mechanism may involve several targets and pathways.
