Blue Nevus Hidden within the Nevus of Ota / 中国医学科学杂志(英文版)

A 3-year-old boy presented with bluish patch and scattered blue spots on the left side of his face. After several sessions of laser treatment, the azury patch in the periorbital area became even darker. Histopathology showed many bipolar, pigment-laden dendritic cells scattered in the papillary and upper reticular dermis. Immunohistochemically, these cells were positive for S100, SOX-10, melan-A, P16, and HMB-45. The positive rate of Ki-67 was less than 5%. Finally, the lesion was diagnosed with nevus of Ota concurrent with common blue nevus. Therefore, for cases of the nevus of Ota with poor response to laser treatment, the possible coexisting diseases should be suspected.

Application of Artificial Intelligence in Clinical Genomics / 中国医学科学院学报

Clinical genomics mainly studies the clinical application of genomics in diagnosis,treatment decision,and prognosis prediction.Artificial intelligence enables the processing of complex and massive data in genomics which are difficult to be dealt with traditional algorithms and techniques.At present,artificial intelligence is involved in many tasks of clinical genomics,such as variant calling and classification,imaging and genetic diagnosis,electronic health record-based genetic diagnosis,and prediction of drug effect and adverse reaction.This review elaborates the application of artificial intelligence in different aspects of clinical genomics.

The Anti-Inflammation Effect of Atorvastatin on Myocardial Hypertrophy Caused by Pressure Overload / 中华高血压杂志

Background A multitude of studies reported statins prevent the myocardial hypertrophy induced by pressure overload,but the mechanism is unclear.Objective To study the protective effect of atorvastatin on the myocardial hypertrophy caused by pressure overload and it's anti-inflammation effect.Methods Forty Wistar rats were randomized to untreated group(n=10),atorvastatin group(2 mg/kg?d,by gavage,n=10),sham op- eration group(n=10)and control group(n=10).Ventricular hypertrophy model was achieved by surgical con- stricting the abdominal aorta.All rats were sacrificed 8 weeks after the operation and the heart weight to body ratio,left ventricular weight to body ratio,and the size of cardiomyocyte were determined.The expressions of interleukin 18(IL-18)and cardiotrophin 1(CT-1)in the cadiocyte were assessed by reverse transcription polymer- ase chain reaction(RT-PCR).Results Compared with control group,SBP in myocardial hypertrophy group was significantly increased(174?9 vs control 112?15 mmHg,P
