Objective To study the MR imaging characteristics of benign cerebellar astrocytomas(BCAs) in children. Methods The clinical and MR imaging data of twelve patients with BCAs were reviewed and analyzed retrospectively.Results Of 12 tumors, 7 cases were located in the cerebellar hemisphere, 4 in the vermis, and 1 in the IV ventricle. All children were in company with hydrocephalus rated as extensive (n=9) or moderate (n=3). The tumors ranged in diameter from 23 mm to 68 mm, mean diameter 42 mm. Solid tumors were found in 5 children, and cystic areas occurred in 7 of 12 patients.BCAs were hypointense on T 1-weighted in 10 cases, and hyperintense on T 2WI in 9 cases compared with that of normal brain parenchyma. After contrast injection, BCAs marked (n=2), moderate (n=5), or absent (n=5) enhancement. Hemorrhage and calcification were not common (n=1,0, respectively).Conclusion BCAs has relative characteristic features on MRI in children, and MRI plays an important role in diagnosing and evaluating these tumors preoperatively.

Purpose:
The aim of this study was to evaluate the value of elastography in the differential diagnosis of benign versus malignant testicular lesions.
Methods:
The PubMed, Cochrane Library, and Embase databases were searched for relevant studies. The diagnostic accuracy of elastography was evaluated using pooled sensitivity, specificity, likelihood ratio, post-test probability, diagnostic odds ratio, and by summarizing the area under the hierarchical summary receiver operating characteristic (HSROC) curve.
Results:
Seven studies with 568 lesions were included. The pooled sensitivity and specificity were 87% (95% confidence interval [CI], 81% to 92%) and 81% (95% CI, 65% to 90%), respectively. The pooled estimates of the positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 4.48 (95% CI, 2.37 to 8.47), 0.16 (95% CI, 0.10 to 0.25), and 28.11 (95% CI, 11.39 to 69.36), respectively. The area under the HSROC curve was 90% (95% CI, 88% to 93%).
Conclusion
Elastography is useful for assessing the stiffness of testicular lesions and for differentiating benign from malignant lesions. Elastography can be an effective supplement to conventional ultrasonography.

The status of lymph node metastasis is an important prognostic factor for many malignant tumors, including lung cancer. In the 8th edition of the TNM staging system for lung cancer, the T staging had obvious changes and refinements, but the N staging had little changes. Recently, several studies have found that the prognosis of patients with the same N stage can vary greatly, suggesting that a more detailed subgroup of patients with the same N stage should be subdivided, including the inclusion of extra-capsular lymph node metastases (ENE). In this review, we reviewed the definition, classification/grading, imaging diagnosis, pathological diagnosis, related molecular markers and their relationship with the prognosis of lung cancer patients.

OBJECTIVE:
To explore the genetic basis of a fetus with ventricular septal defect (VSD) by using modified noninvasive prenatal testing (NIPT) for the detection of microdeletion syndromes.
METHODS:
Chromosomal karyotypes of the fetus and its parents were analyzed by G-banding technique. Next generation sequencing (NGS) was used to detect genomic copy number variations (CNVs) in cell-free fetal DNA. The results were verified by fluorescence in situ hybridization (FISH).
RESULTS:
The fetus and its parents all had a normal karyotype at 320-400 band level. NGS revealed a deletion of 1.30 Mb at 7q11.23 in the fetus, with a 93% overlap with that of Williams-Beuren syndrome (WBS). The father also had a deletion of 1.42 Mb at 7q11.23, with a 99% overlap with that of WBS. Modified NIPT also detected the 1.30 Mb deletion at 7q11.23 in the fetus. The result of FISH has confirmed the above results.
CONCLUSION
It is necessary to carry out genetic testing on fetuses with VSD. NGS can detect fetal microdeletion syndromes and help to trace their parental origin. The modified NIPT for fetal chromosomal microdeletions/microduplication syndromes is highly accurate.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

BACKGROUND:
Limited data are available on the comparison of clinical outcomes of complete vs. incomplete percutaneous coronary intervention (PCI) for patients with chronic total occlusion (CTO) and multi-vessel disease (MVD). The study aimed to compare their clinical outcomes.
METHODS:
A total of 558 patients with CTO and MVD were divided into the optimal medical treatment (OMT) group ( n = 86), incomplete PCI group ( n = 327), and complete PCI group ( n = 145). Propensity score matching (PSM) was performed between the complete and incomplete PCI groups as sensitivity analysis. The primary outcome was defined as the occurrence of major adverse cardiovascular events (MACEs), and unstable angina was defined as the secondary outcome.
RESULTS:
At a median follow-up of 21 months, there were statistical differences among the OMT, incomplete PCI, and complete PCI groups in the rates of MACEs (43.0% [37/86] vs. 30.6% [100/327] vs. 20.0% [29/145], respectively, P = 0.016) and unstable angina (24.4% [21/86] vs. 19.3% [63/327] vs. 10.3% [15/145], respectively, P = 0.010). Complete PCI was associated with lower MACE compared with OMT (adjusted hazard ratio [HR] = 2.00; 95% confidence interval [CI] = 1.23-3.27; P = 0.005) or incomplete PCI (adjusted HR = 1.58; 95% CI = 1.04-2.39; P = 0.031). Sensitivity analysis of PSM showed similar results to the above on the rates of MACEs between complete PCI and incomplete PCI groups (20.5% [25/122] vs. 32.6% [62/190], respectively; adjusted HR = 0.55; 95% CI = 0.32-0.96; P = 0.035) and unstable angina (10.7% [13/122] vs. 20.5% [39/190], respectively; adjusted HR = 0.48; 95% CI = 0.24-0.99; P = 0.046).
CONCLUSIONS
For treatment of CTO and MVD, complete PCI reduced the long-term risk of MACEs and unstable angina, as compared with incomplete PCI and OMT. Complete PCI in both CTO and non-CTO lesions can potentially improve the prognosis of patients with CTO and MVD.
