Objective: To summarize the clinical phenotype, gene variation and imaging findings of a case presenting ACTA2 mutation induced muti-systemic smooth muscle dysfunction syndrome combined with ***: We collected the clinical materials and laboratory findings of a case with ACTA2 mutation induced seizure admitted to our hospital in December 2018. Peripheral blood samples were extracted from the patient and her parents for blood DNA extraction. The samples were subject to exon chip capture and whole exon sequencing using the Sanger technique. Literature research from Pubmed and Medline was performed in the published articles before December 2018 using the following key words: ACTA2 gene and muti-systemic smooth muscle dysfunction syndrome. The clinical manifestations, laboratory test results and prognosis from the cases with ACTA2 mutation induced mutisystemic smooth muscle dysfunction syndrome were ***: The routine blood examination, biochemical test and metabolism showed no aberrant changes. Cerebral MRA indicated stiffness in the brain vessels, together with multiple aberrant signal shadows in brain. Cardiac ultrasonography revealed congenital heart disease, patent ductus arteriosus(PDA, with a diameter of 0.68 cm), slight left coronary arteriectasis, patent oval foramen(with a diameter of 0.12 cm), slight tricuspid and pulmonary regurgitation, as well as pulmonary hypertension. The patient showed 4 times of seizure before treatment, and no onset of seizure was reported since oral administration of sodium valproate for 6 months. A heterozygous mutation(c.536 C>T) was identified in the ACTA2 gene, which resulted in generation of p.R179 ***: ACTA2 gene mutation is pathogenic for muti-systemic smooth muscle dysfunction syndrome with various clinical manifestations. Lesions in the vessels and alba in patients with smooth muscle dysfunction syndrome may lead to onset of seizure.

In this paper, we introduce a novel method for facial landmark detection. We localize facial landmarks according to the MAP crite rion. Conventional gradient ascent algorithms get stuck at the local optimal solution. Gibbs sampling is a kind of Markov Chain Monte Carlo （MCMC） algorithm. We choose it for optimization because it is easy to implement and it guarantees global conver gence. The posterior distribution is obtained by learning prior distribution and likelihood function. Prior distribution is assumed Gaussian. We use Principle Component Analysis （PCA） to reduce the dimensionality and learn the prior distribution. Local Linear Support Vector Machine （LLSVM） is used to get the likelihood function of every key point. In our experiment, we compare our de tector with some other wellknown methods. The results show that the proposed method is very simple and efficient. It can avoid trapping in local optimal solution.

Similarity coefficient mapping（SCM） aims to improve the morphological evaluation of T＊2weighted magnetic resonance imaging（T＊2-w MRI）. However, how to interpret the generated SCM map is still pending. Moreover, is it probable to extract tissue dissimilarity messages based on the theory behind SCM？ The primary purpose of this paper is to address these two questions. First, the theory of SCM was interpreted from the perspective of linear fitting. Then, a term was embedded for tissue dissimilarity information. Finally, our method was validated with sixteen human brain image series from multiecho T＊2-w MRI. Generated maps were investigated from signal-to-noise ratio（SNR） and perceived visual quality, and then interpreted from intra- and inter-tissue intensity. Experimental results show that both perceptibility of anatomical structures and tissue contrast are improved. More importantly, tissue similarity or dissimilarity can be quantified and cross-validated from pixel intensity analysis. This method benefits image enhancement, tissue classification, malformation detection and morphological evaluation.

Purpose: This study aimed to evaluate the value of precise localization of nodules using pre-video-assisted thoracic surgery(VATS) Xper–CT in combination with real-time fluoroscopy-guided coil in the resection of pulmonary nodules using VATS. Materials and Methods: Precise localization of nodules using Xper-CT in combination with real-time fluoroscopy-guided coil and wedge resection using VATS were conducted on 15 patients with 17 small pulmonary nodules(diameter 0.5–1.5 cm) from April 2015 to January 2016. The value of localization was evaluated in terms of procedure time, type of coils, associated complications of localization, and VATS success rate. Results: The success rate of coil localization was found to be 100% in the primary stage(as shown by the CT scan), and the average procedure time was 30–45 min(35.6 ± 3.05 min). No deaths or major complications occurred. Minor complications included five incidents of pneumothorax(the morbidity was 29.4%, 5/17; no patient required chest tube drainage). The dislocation of coil was found in one patient. The results of pathological examination of 17 small pulmonary nodules revealed 11 primary lung cancers, 1 mesenchymal tumor, 3 nonspecific chronic inflammations, 1 hamartoma, and 1 tuberculosis. Two patients with primary lung cancer underwent lobectomy with mediastinal lymph node dissection. Conclusion: The preoperative precise localization of small pulmonary nodules using Xper-CT-guided coil is an effective and safe technique. It helps in the resection of nodules using VATS. It increases the rate of lung wedge resection with few complications and allows for proper diagnosis with a low thoracotomy conversion rate.
