Objective To study the pathological morphology of thyroid specimen after thyroid arteries embolization. In order to select appropriate size of embolizing granules, the diameters of thyroid arteries in Graves' disease were measured. Methods Multiple slides of embolized thyroid tissues from superior pole, body and inferior pole of the resected thyroid glands were made. After being embedded and stained, pathological morphology was observed and diameters of arteries in various parts of thyroid glands were measured under microscopy. Results Pathological examination of thyroid glands showed that superior and inferior thyroid arteries and most of their branches were embolized with ischemic necrosis and fibrosis in the embolized thyroid tissue. Follicular epithelium appeared as flat or cubic shapes with colloid reduction. Average diameter of main branches of superior artery was 440~550?m and that of inferior artery was 300~375?m. The diameters of capillary network in the thyroid body was 120~250?m, and the non embolized ones was 40~110?m. The diameter of isthmus was 130~150?m. Conclusions Pathological morphology of Graves' disease after thyroid arteries embolization showed that the excretion of thyroid glands would be decreased and equivalents to subtotal thyroidectomy.

Objective To investigate the age-associated changes of ultrastructure,mRNA and protein expressions of H+-K+-ATPase in elderly gastric parietal cell. Methods Fifty patients with relative normal stomach without gastroduodenal diseases were enrolled,including younger group (aged 20-59 years,n=19) and elderly group (aged≥60 years,n=31).Furthermore,the elderly group was divided into 3 subgroups:60-69 years old (n =11 ),70-79 years old (n=10 ),above 80 years old (n =10).The ultrastructure of gastric parietal cell was observed under electron microscope.The expression of H+-K+-ATPase α subunit mRNA and H+-K+-ATPase β subunit protein were assessed by quantitative real-time PCR and Western-blot,respectively.The ageing-associated changes of all these data were respectively compared. Results No significant difference was showed in the morphology of gastric parietal cell and acid-secretion-associated organelles among all the groups.The average ratio Am to Ac (Am means the area of mitochondria,Ac means the area of cytoplasm) of gastric parietal cell and the average At to Ac ratio (At means the area of secretory canaliculi and tubulovesicular system )between younger group and elderly group had no significant difference[(48.4±7.5) % vs.(50.6±7.6) %,t=-0.775,P=0.444; (13.8±4.1) % vs.(12.2±4.7) %,t=0.984,P=0.332].Meanwhile,there were no distinctions in the expression of H+-K+ -ATPase α subunit mRNA and H+-K+-ATPase protein among all elderly subgroups(F=1.522,2.32,P=0.24,0.114).However,the mRNA expression of H+-K+-ATPase a subunit was higher in the elderly group than in the younger group(t=-3.682,P=0.001).Furthermore,the expression of H+ -K+ -ATPase protein in the elderly group was increased as compared with younger group(t=-3.389,P=0.004). Conclusions Acidsecretion-associated organelles of human gastric parietal cell have no degeneration and the expression of H + -K+-ATPase is in trend of increase with aging,indicating that healthy elderly people have the basis of ultrastructure and molecular biology to maintain well function of acid secretion.

Journal of China Medical University 2017;46(8):673-676
Objective We screened for mutations in an autosomal dominant congenital cataract pedigree by gene sequence analysis to provide a basis for genetic diagnosis of congenital cataract.Methods A Chinese family with congenital nuclear cataract was recruited for mutational screening of candidate genes by direct sequencing.We analyzed the differences between the CRYGD gene mutant and wild-type in terms of protein conformation and structural domains using bioinformatics methods.Results We detected a novel heterozygous variant c.451_452insGACT in exon 3 of CR YGD.Bioinformatics analysis showed that the mutated CRYGD protein structural domain became shorter,the conformation became simpler,and protein inner repeatability was altered,affecting protein function.Conclusion We found that the Tyr1 51X gene mutation of CRYGD can lead to congenital hereditary cataract.To date,this is the only detected frameshift mutation caused by an insertion in CRYGD gene mutations.

Twenty-three patients with uniloculated deep neck abscesses (UDNA),in whom the antibiotic therapy failed and CT-guided percutaneous catheter drainage (PCD) was performed from January 2005 to June 2015,were included in the study.Catheter placement was carried out using Trocar technique in all cases.Open surgical drainage was performed when PCD procedures failed.The abscess was completely drained and open surgical drainage was avoided in 19 cases (83%);the surgical drainage was performed because of muhiple internal septation in 3 (13%) case,and 1 (4%) case died from uremia.In this series the technical success rate and clinical success rate of PCD were 96% (22/23) and 83% (19/23),respectively.All patients were followed-up by CT scan.No other complications and no mortality occurred during the procedure,while postoperative pneumatosis developed in 1 case.CT-guided PDC is a safe and highly effective low-cost procedure for the treatment of patients with UDNA who failed medical therapy,it may be considered as an alternative to open surgery.

Objective To address the neural basis of Chinese idioms processing with different kinds of stimuli using an event-related fMRI design.Methods Sixteen native Chinese speakers were asked to perform a semantic decision task during fMRI scanning.Three kinds of stimuli were used: Real idioms (Real-idiom condition);Literally plausible phrases (Pseudo-idiom condition,the last character of a real idiom was replaced by a character with similar meaning);Literally implausible strings (Non-idiom condition,the last character of a real idiom was replaced by a character with unrelated meaning).Reaction time and correct rate were recorded at the same time.Results The error rate was 2.6%,5.2% and 0.9% (F = 3.51,P0.05 )for real idioms,pseudo-idioms and wrong idioms, respectively.Similar neural network was activated in all of the three conditions.However,the right hippocampus was only activated in the real idiom condition,and significant activations were found in anterior portion of left inferior frontal gyrus (BA47)in real-and pseudo-idiom conditions,but not in non-idiom condition.Conclusion The right hippocampus plays a specific role in the particular wording of the Chinese idioms.And the left anterior inferior frontal gyms (BA47)may be engaged in the semantic processing of Chinese idioms.The results support the notion that there were specific neural bases for Chinese idioms processing.

The aim of this study was to investigate the anti-inflammatory effect of Guizhi Fuling capsule and its active complex (consistent of 15 active compounds) on LPS-induced RAW264. 7 cells. The effect of Guizhi Fuling capsule and its active complex on cell viability in RAW264. 7 cells were determined by MTT assay. The inhibitory effect of Guizhi Fuling capsule and active complex on the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells was detected by ELISA assay. The expression of IL-1β and mPGES-1 in Guizhi Fuling capsule or active complex treated RAW264. 7 cells was examined by Western blot assay. Guizhi Fuling capsule and active complex showed no significant effect on the cell viability in RAW264. 7 cells at doses range from 12.5 to 400 mg x L(-1). Compared with LPS treated group, Guizhi Fuling capsule and active complex dose dependently reduced the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells. Moreover, the expression of IL-1β and mPGES-1 was decreased after Guizhi Fuling capsule and active complex treatment, which might contribute to the inhibitory effect of Guizhi Fuling capsule in the releasing of IL-1β, TNF-α and PGE2. This study provided the evidence that Guizhi Fuling capsule and active complex remarkably inhibited the releasing of IL-1β, TNF-α and PGE2induced by LPS in RAW264. 7 cells by reducing the expression IL-1β and mPGES-1. This study provided an experimental basis of Guizhi Fuling capsule for the treatment of inflammation and a theoretical basis for the development of effective compounds of Guizhi Fuling capsule.
