Colon cancer arises from the accumulations of genetic and epigenetic changes. Currently, profiles of DNA methylation and gene expression of colon cancer have not been elucidated clearly. This articles aims to characterize the profile of DNA methylation and gene expression of colon cancer systemically, and acquire candidate genes potentially regulated by altered methylation for this disease. ⋯ In addition, the 3 genes were involved in brown module of WGCNA, indicating their important roles in colon cancer. The investigation of the relationship between DNA methylation and gene expression may help to understand the effect of DNA methylation alteration on genes expression, especially gene co-expression network in the development of colon cancer. Genes such as ADHFE1, HAND2, and GNAO1 may be served as potential candidates for diagnosis and therapy targets in colon cancer.

Osteosarcoma is the most common malignant bone tumor in children and adolescents. Metastasis occurs early, the mortality rate is high, and the tumor results in a tremendous physical, mental, and economic burden on patients. Therefore, the treatment of osteosarcoma has been important for orthopedic surgeons. However, treatment has always been a difficult problem globally. ⋯ Our case indicated that limb osteosarcoma patients can undergo a limb salvage program of local arterial infusion chemotherapy, systemic intravenous chemotherapy, and curettage.

Diagnosis of fetal megacystis with chromosomal abnormality by 2D prenatal ultrasound: A case report.
The pathogenesis of fetal megacystis is divided into obstructive and nonobstructive. Megacystis combined with chromosomal abnormalities is rare and most of the cases are nonobstructive. ⋯ In conclusion, this case suggests that in the presence of fetal megacystis and multisystem abnormalities, causes should be investigated and the possibility of chromosomal abnormalities should be considered in the presence of multisystem developmental abnormalities.

Traditional digital subtraction angiography (DSA) provides lumen morphology of renal artery as indicators for vascular patency in patients with renal artery stenosis (RAS). It, however, lacks hemodynamic information toward target kidney. To solve this shortcoming, a novel technique, flat-panel detector parenchymal blood volume imaging (FD-PBV), is introduced, which is able to evaluate hemodynamic changes of target kidney intraoperatively. ⋯ FD-PBV technique possesses a remarkable value in quantitatively assessing the changes of kidney blood perfusion and can be a useful auxiliary technique for DSA.

We evaluated the readability of Internet-sourced patient education materials (PEMs) related to "labour analgesia." In addition to assessing the readability of websites, we aimed to compare commercial, personal, and academic websites. We used the most popular search engine (http://www.google.com) in our study. The first 100 websites in English that resulted from a search for the key words "labour analgesia" were scanned. ⋯ Analysis of 300-word sections of the texts revealed that the mean FRES was 47.54 ± 12.54 (quite difficult), mean FKGL and SMOG were 11.92 ± 2.59 and 10.57 ± 1.88 years of education, respectively, and mean Gunning FOG was 14.71 ± 2.76 (very difficult). Within 300-word sections, the mean number of Latin words was identified as 16.56 ± 6.37. In our study, the readability level of Internet-sourced PEM related to "labour analgesia" was identified to be quite high indicating poor readability.
