To the Editor： Periventricular nodular heterotopias （PNHs） represent a malformation of cortical development caused by an improper neuronal migration during forebrain formation, There is a wide spectrum of anatomical and clinical presentations of PNH, ranging from asymptomatic small unilateral or bilateral nodules to extensive agglomerates of heterotopia lining the lateral ventricles with epilepsy and intellectual disabilities. The mutations in X-linked gene, filamin A （FLNA） gene, were identified in approximately 100% of familial PNHs and 25% of sporadic cases Here, we reported a novel frameshift mutation of FLNA gene in a Chinese family with PNH.

AIM： TO assess the hepatic microvascular parameters in patients with liver cirrhosis by perfusion computed tomography （CT）. METHODS： Perfusion CT was performed in 29 patients without liver disease （control subjects） and 39 patients with liver cirrhosis, including 22 patients with compensated cirrhosis and 17 patients with decompensated cirrhosis, proved by clinical and laboratory parameters. CT cine-scans were obtained over 50 s beginning with the injection of 50 mL of contrast agent. Hepatic microvascular parameters, mean transit time （MTT） and permeability surface area product （PS） were obtained with the Perfusion 3 software （General Electric, ADW 4.2）. RESULTS： The overall differences of MTT and PS between control subjects, patients with compensated cirrhosis and those with decompensated cirrhosis were statistically significant （P = 0.010 and P = 0.002, respectively）. MTT values were 15.613 ± 4.1746 s, 12.592 ± 4.7518 s, and 11.721 ± 4.5681 s for the three groups, respectively, while PS were 18.945 ± 7.2347 mL/min per 100 mL, 22.767 ± 8.3936 mL/min per 100 mL, and 28.735 ± 13.0654 mL/min per 100 mL. MTT in decompensated cirrhotic patients were significantly decreased compared to controls （P = 0.017）, whereas PS values were remarkably increased （P = 0.001）.CONCLUSION： The hepatic microvascular changes in patients with liver cirrhosis can be quantitatively assessed by perfusion CT. Hepatic microvascular parameters （MTr and PS）, as measured by perfusion CT, were significantly altered in decompensated cirrhosis.

Recycling precious metals with high-efficiency is undoubtedly beneficial to optimize resource utilization for environmental remediation and sustainable ***,we report an efficient route to recycle the palladium(Pd)and platinum(Pt)electrocatalysts using a phase transfer *** strategy involves acidic dissolution of deactivated precious metal(Pd/Pt)electrocatalysts from their loading substrates,mixing with an ethanolic solution of dodecylamine(DDA),subsequent extraction of metal ions into a non-polar organic phase,and final reduction by sodium borohydride to reproduce high-performance electrocatalysts towards typical electrochemical reactions,e.g.,oxygen reduction reaction(ORR)and ethanol oxidation reaction(EOR).In specific,the transfer efficiencies are up to 98%and the final recovery rate is over 85%for Pd and Pt electrocatalysts in each *** approach symbolizes a facile and efficient way to recover precious metals,which might be applied to recycling a wide range of metals in various realms after appropriate modifications.
