A strain was separeted from the Yueqing bay using pine pollen baiting.The vegetative thallus of the separated strain is oval and unincleate.It possesses a cell wall composed of many compact layers of closely pressed scales, which can be resolved where the cell wall is disrupted.The radiating branched extensions of the thallus, the ectoplasmic net, emerges from the sagenogenetosome.Asexual reproduction is by conversion of the vegetative thallus to many biflagellate zoospores, during which tetrads of cells are formed.It was identified with Schizochytrium sp.based on the features mentioned above.

ObjectiveTo explore the characteristics of phonological encoding of Chinese disyllabic compound words in patients with mild cognition impairment(MCI). Methods10 patients with MCI and 10 normal controls who matched with the age, gender, level of education and handedness performed homophone judgment task. In this task, a picture with a disyllabic compound name was presented, after 100 ms of the presentation there would be a Chinese character below the picture. Subjects were asked to judge whether one of the morpheme in the picture name was homophonic to the character. The reaction time and error ratio were analyzed statistically. ResultsIn the normal controls, the reaction time for the second constituents was shorter than that for the first constituents, while there were no difference between the first and second constituents reaction time in MCI patients. The error ratio of the first and second constituents showed no difference in normal controls, but MCI patients made more error rate for the first constituents. ConclusionAs the heathy elderly,the MCI patients have same pattern in phonological coding of Chinese disyllabic compound words, but much slower in activation speed, indicating the impairment of semantic memory and phonological activation in patients with MCI.

Objective To discuss some characteristics of aggressive behavior of junior middle school students addicted to violence online game.Methods From Aug.to Dec.at 2009,6000 volunteers have been investigated with the self-made violence online game survey scale and the Chen's were screen out by CIAS,and in which 71 violence game addicts,and 66 entertainment game addicts.They were divided into two groups matched as age and sex(male 55 and female 11 in every group),average age was 14.36±0.81 years old.66 no-play game students served as control group.The mean value and standard deviation of aggressive behaviors in each group were compared with one way ANOVA with SPSS12.0 version.Results There were significant different inter groups in the behavioral scores expressed in physiological attack((21.59±4.36),(18.10±6.10,(14.92±5.61)),spoken language attack((21.04±3.98),(18.36±6.26),(15.66±5.23)),angry mood((21.37±4.43),(18.72±5.90),(16.56±5.70)),hostility cognition((21.69±5.77),(20.06±7.74),(16.39±6.85))and the total score((85.56±13.71),(75.28±22.36),(63.54±20.32))(F1-4=25.07,17.35,3.25,10.40,21.81);Moat severity attack behaviors were observed in the violence online game addictive group,but less done in other two groups(t1-4=3.48,2.68,2.65,10.27,P<0.01;t 1-5=6.66,5.37,4.48,5.30,22.01,P<0.01);and secondary was found in Entertainment online game addicts(t1-5:3.18,2.69,2.16,3.66,11.74,P<0.01).Conclusion Higher attack behavior scores are found in the violence online game in junior middle students,and entertainment online game also induce attack behavior,but is not so notable.

Data were gathered from epidemiological survey of Xinjiang Hetian area in 2008 and 2 228 subjects were included.Waist-height ratio (WHtR),body mass index (BMI),Waist-hip ratio (WHpR) were calculated.Kappa test was applied to determine the concordance among different methods.The results showed that according to International Diabetes Federation 2005 diagnostic criteria for metabolic syndrome,it was better to apply WHtR in predicting metabolic syndrome by the receiver operating characteristic (ROC) curve than BMI,abdominal circumference,and WHpR.When the cutoff of WHtR was 0.53,the sensitivity and specificity in diagnosing MS were 91.2％ and 71.8 ％,with its area under ROC curve 0.878.Kappa test showed an intensive concordance between WHtR and waist circumference (WC).The specificity and sensitivity of diagnosing MS would be significantly raised by using both WHtR and WC.

Objective To investigate the relationship between SOCS-3 gene polymorphism and abnormal glucose metabolism in Xinjiang Uygur population.Methods According to different plasma glucose levels,1232individuals in Xinjiang Hetian area were divided into 3 groups,451 patients with pre-diabetes,252 patients with type 2 diabetes mellitus,and 529 healthy people as normal controls.Based on HapMap,the polymorphisms rs12953258,rs4969168,rs9914220 were selected as haplotypes,tagging SNP (htSNP) sufficiently covering the genetic variation of the whole gene.Associations of rs12953258,rs4969168,and rs9914220 within SOCS-3 with abnormal glucose metabolism in three groups of Xinjiang Uygur population were examined ; The genotype and allele frequencies and relative clinic data were compared among groups.Results The type 2 diabetes mellitus study with 451 individuals showed that the homozygosity for the C allele of rs12953258 polymorphism of SOCS-3 was associated with increased diabetes risk(OR=1.756,95％ CI 1.168-2.640).In addition,association between rs4969168 or rs9914220 and abnormal glucose metabolism in the Xinjiang Uygur population was not found.Age,total cholesterol,and body mass index were risk factors of diabetes mellitus,total cholesterol and low high density lipoprotein-cholesterol were risk factors of pre-diabetes in Uygur people.Conclusions The C allele of rs12953258 polymorphism of SOCS-3 gene may be an independent risk factor for abnormal glucose metabolism in Xinjiang Uygur population.

Objective This study is about to detect the KCNJ5 gene variations in aldosterone-producing adenoma (APA) with primary hyperaldosteronism (PA),and to investigate the association of the KCNJ5 gene missense mutations with APA and PA.Methods A total of 46 APA tumors and their clinical characteristics were collected from Hypertension Center of the People's Hospital of Xinjiang Uygur Autonomous Region,and all the tumors were confirmed by pathology.All the samples of the coding region segments of KCNJ5 were detected by PCR and direct DNA sequencing to compare the different missense mutations in the tumor cells and peripheral blood cells and to analyze the association between the genotype and phenotype.Results Three missense mutations were found in 46 patients with APA:c.451G ＞ C/A (p.G151R) (5/46),c.503T ＞ G (p.L168R) (4/46),c.830T ＞ A (p.S209T) (12/46).S209T,as an unreported somatic mutation was observed.There were no missense mutations detected in the peripheral blood.Sex,age,systolic blood pressure,diastolic blood pressure,duration of hypertension,plasma potassium,urine potassium,aldosterone,plasma renin activity,aldosterone,and plasma renin activity ratio,as well as the rate of positive family history were compared between the mutants and wild-types.Systolic blood pressure and plasma potassium level among G151 R,L168R,and S209T had statistical differences.Systolic blood pressure in G151R was significantly higher than the other two groups,while the plasma potassium level was significantly lower than the other groups.Conclusions Three missense mutations were found in 46 patients with APA.The subjects with mutations had more serious condition than those without mutations after comparing their clinical phenotype.Besides,other different subtypes may exist in PA.

Objective To assess the left ventricular synchronization and global systolic function in patients with implanted dual-chamber (DDD) mode cardiac pacemakers by real-time three-dimensional echocardiography(RT-3DE). Methods Left ventricular systolic synchronization and global function were evaluated in 20 patients with implanted DDD mode cardiac pacemakers and 20 normal people by RT-3DE. The left ventricular end-diastolic volume (LEDV), end-systolic volume ( LESV), stroke volume (SV), left ventricular ejection fraction (LVEF), the mean value of time from the start of electrocardiographic QRS wave to the point of minimal systolic volume (Tmean) of the 17 segments and those standard deviation(T-SD),the maximal difference of time among all 17 segments(Tmax) were obtained by RT-3DE. Results Compared with control group, LESV was significantly increased,SV, LVEF were significantly decreased and T-SD,Tmax were significantly prolonged (P <0.01 ). There were no differences in LEDV and Tmean between the two groups (P>0.05). In patients group,LVEF correlated closely with T-SD (r =-0.674, P<0.05) and Tmax (r = - 0. 634, P < 0. 05). Conclusions There were left ventrieular systolic asychronization and global systolic dysfunction in patients with implanted dual-chamber (DDD) mode cardiac pacemakers,which could be assessed by RT-3DE.

OBJECTIVE:To optimize the purification technology of total alkaloid from the flos of Aconitum kusnezoffii. METH-ODS:The content of total alkaloid from the flos of A. kusnezoffii was determined by acid-base titration. The purification technology of total alkaloid from the flos of A. kusnezoffii was optimized by ion resin with resin type,mass concentration of loading liquid and exchange speed as factors,maximum adsorption quantity,desorption rate and mass fraction of total alkaloid as index,and verifica-tion test was conducted. RESULTS:The optimal purification technology was as follows as type 732 cation exchange resin,mass concentration of loading liquid 0.32 g/L,exchange speed of 7 column volume(BV)/h. In validation test,the content of total alka-loid was 86.88%(RSD=0.52%,n=3),and desorption rate was 92.81%(RSD=0.40%,n=3)averagely.

Objectivc To observe the short-term changes of anterior corneal biometry after discontinuation of orthokeratology in patients with 2-year wearing.Methods Retrospective study.Sixty myopic patients aged from 8-14 years old during October 2012 and October 2014 were wearing orthokeratology for 2 years in Tianjin Medical University Eye Hospital.According to the degree of myopia,they are divided into three groups(SE≤-2.00 D for group A,-2.00 D ＜ SE ≤-4.00 D for group B and -4.00 D ＜ SE ≤-6.00 D for group C).The recovery of anterior corneal curvature,including flat K(FK),steep K(SK),average K (AVEK),changes of axial length and central corneal thickness (CCT) at 1 week,2 weeks,1 month after discontinuation of orthokeratology were observed.Results There was no statistical differences in FK,SK,AVEK before and 2 weeks after wearing orthokeratology in group A (all P ＞ 0.05).While in group B,there was no significant difference in FK,SK,AVEK before and 1 month after wearing orthokeratology;There were statistically differences in FK,SK,AVEK at 1 month after discontinuation in group C compared with the baseline (all P ＜0.05).As for CCT,there was no statistical differences among group A,B,C after discontinuation of orthokeratology for 2 weeks (all P ＞ 0.05).There were statistical differences in the axial length between 1 week and 2 weeks after discontinuation of orthokeratology in group B and C (all P ＜ 0.05);There were statistical differences in the axial length between 1 month and 2 weeks after discontinuation of orthokeratology in three groups (all P ＜ 0.05);Compared with the state before wearing orthokeratology,the increase of axial length in group A,B,C were (0.43 ± 0.36) mm,(0.35 ± 0.21)mm and (0.36 ± 0.29) ram,respectively.Conclusion The time course of returning to the original corneal parameter varies among different degree of myopia,and the axial length has no significant growth after short-term discontinuation.

Objective To investigate the value of ultrasound in tethered cord syndrome (TCS) in infants. Methods From December 2005 to July 2013, 25 cases TCS were confirmed by surgery in Shenzhen children's hospital. The ultrasonogram and MRI of 25 infants were analysed retrospectively. The diagnostic accuracy of ultra-sound and its clinical significance were evaluated. Results In 25 cases of TCS confirmed by surgery, the coincidence rate of conus level detected by ultrasound [96%(23/24)] was lower than that by MRI (100%(25/25)). Ultrasound showed reduced spinal cord vibration in 4 cases, disappeared spinal cord vibration in 21 cases. Two cases of reduced spinal cord vibration detected by ultrasound were confirmed as disappeared spinal cord vibration by surgery. The coincidence rate of disappeared spinal cord vibration detected by ultrasound was 91%(21/23). The sacral spinal seg-ments form showed by ultrasound were entirely consistent with those of MRI, including 4 cases of enlarged spinal cord, 13 cases of spinal cord without enlargement and 8 cases of spinal cord ended with rat caudate. Twenty-five cases of TCS had malformations:7 cases meningocele (3 cases combined lipoma), 14 cases myelomeningocele (5 cases combined lipoma, 1 case combined hydromyelia), 3 cases spinal canal-epidermis fistula (all combined lipoma) and 1 case solitary lipoma. Compared with the operation findings, ultrasound misdiagnosed 2 cases of myelomeningo-cele as meningocele, missed 1 of case lipoma which combined with meningocele. MRI missed two cases of spinal canal-epidermis fistula. Conclusions Infantile spinal ultrasound examination can accurately locate the position of conus, accurately display the spinal cord. Compared with MRI, ultrasound examination can real-time visually display spinal cord vibration and help to diagnose tethered cord. Ultrasound examination are convenient, repeatable opera-tion with low cost, therefore it can be used as the preferred screening method to diagnose of tethered spinal cord.
