Conclusion: The abnormal expression of VEGF and mutant p53 may be related to the degree of deterioration of the stomach tissue lesions related.

Objective To investigate the clinical characteristics of primary gastrointestinal lymphoma (PGIL) on different origin site in order to improve its diagnosis.Methods The clinical data from 202 patients with PGIL diagnosed by histology from January 1999 to June 2007 were identified from the clinical databases of 8 hospitals in Wuhan area and retrospectively analyzed.The patients were divided into gastric,small intestinal and large intestinal lymphoma groups according to the site of origin and there clinical characteristics were compared.Results The PGIL localization was gastric in 113 (56.0%) cases, small intestine in 37(18.3%) cases and large intestine in 52 (25.7%) cases.One hundred and thirty (64.4%) were males and 72 (35.6%) were females.The male patients were predominant.The median duration of symptoms in gastric lymphoma group was longer than small intestinal lymphoma group (3.0 months vs.1.0 month,P=0.013).The most common symptoms were abdominal pain and anemia. The clinical stage was Ⅰ E and Ⅱ E in 71.3% of cases.The large intestinal lymphoma group presented more advanced-stage disease compared with gastric lymphoma group (P = 0.014).The frequent histological type was mucosa-associated lymphoid tissue lymphoma (MALT),diffuse large B-cell lymphoma and T-cell lymphoma.Gastric,small intestinal and large intestinal lymphomas presented more frequently as low-grade MALT lymphoma (56.9%),T-cell lymphoma (34.4%) and high-grade B-cell lymphoma (51.1%),respectively (all P value ＜0.05).The common macroscopic type of PGIL were nodular protruding and ulcerative type.Compared with gastric lymphoma,nodular protruding type was more common and ulcerative type was less common in large intestinal lymphoma (P = 0.000).The diagnosis confirmed by endoscopic biopsy were 58.7% (61/104),25.0% (4/16),48.2% (13/27) in gastric,small intestinal and large intestinal lymphoma groups,respectively.Conclusions The clinical characteristics are different in patients with different localization of PGIL including patient characters, initial symptoms,histological classification,clinical stage,macroscopic feature,endoscopic findings. Analysis of these clinical characteristics is helpful to improve its diagnosis.

Objective To observe the effects of liraglutide on GRP78,ATF4,CHOP and TRB3 protein and mRNA expression in rats which fed with high fat diet,and to explore the effect of liraglutide on ATF4/CHOP pathway of pancreas in rats fed with high fat diets.Methods Forty-four male Wistar rats were randomly divided into the control group,high fat group,intervention group 1 and intervention group 2,11 cases in each group.The control group was fed with common food,other 3 groups were fed with high fat diet for 8 weeks.Then the intervention group 1 was given with liraglutide (100 μg · kg-1 · d-1) by subcutaneous injection;the intervention group 2 was given liraglutide (200 μg · kg-1 · d-1) by subcutaneous injection.After 2 weeks medication intervention,the rats were killed.Five rats were taken from each group and performed the hyperinsulinemic englycemic clamp experiment under waking state for calculating the glucose infusion rate (GIR).The fasting blood glucose (FBG),fasting insulin (FINS),serum free fatty acid (FFA),total cholesterol (TC),triglyeeride (TG),low density lipoprotein cholesterol (LDL-C) and high density lipoprotein(HDL) were examined,and islet beta cell function index(HOMA-β) were calculated.PCR and Western blot method were used to detect the expression of pancreas GRP78,ATF4,CHOP and TRB3 protein and mRNA.Results Compared with the control group,the levels of FBG,FFA,TC,FINS,TG and LDL-C in the high fat group were significantly increased,the levels of HDL-C,GIR and HOMA-β were significantly decreased(P＜0.05 or P＜0.01);compared with the high fat group,the levels of HDL-C,GIR and HOMA-β in the intervention group 2 were increased(P＜0.05 or P＜0.01),the other indicators were significantly decreased;compared with the intervention group 1,blood FGB,FFA,TC in the intervention group 2 were decreased,while the levels of GIR and HOMA-β were increased(P＜0.05).Compared with the control group,expression of GRP78,ATF4,CHOP and TRB3 protein and mRNA in the high fat group were significantly increased;compared with the high fat group,the expression of GRP78,ATF4,CHOP and TRB3 protein and mRNA in the intervention group 1 and 2 were gradually decreased with the liraglutide concentration increase.Conclusion Liraglutide can improve insulin resistance and protect pancreatic beta cells in a concentration-dependent manner,its mechanisms may involve in the pancreatic endoplasmic reticulum ATF4/CHOP pathway.

The zinc-finger antiviral protein (ZAP) is a host factor that specifically inhibits the replication of certain viruses by eliminating viral mRNAs in the cytoplasm. In previous studies, we demonstrated that ZAP directly binds to the viral mRNAs and recruits the RNA exosome to degrade the target RNA. In this article, we provide evidence that a DEXH box RNA helicase, DHX30, is required for optimal antiviral activity of ZAP. Pull-down and co-immunoprecipitation assays demonstrated that DHX30 and ZAP interacted with each other via their N terminal domains. Downregulation of DHX30 with shRNAs reduced ZAP's antiviral activity. These data implicate that DHX30 is a cellular factor involved in the antiviral function of ZAP.

OBJECTIVEBenign epilepsy with centro-temporal spikes (BECTs) is a common idiopathic partial epileptic syndrome in childhood, which often affect the pre-school and school-age children and a considerable proportion have comorbidity including lower academic achievement and cognitive impairment. Few studies involved the psychocognitive assessment in such a drug-treatable epileptic syndrome especially in the newly diagnosed and medications-naive group. This study aimed to investigate the cognitive characteristics of children with newly onset BECTs before treatment.

METHODForty-one outpatients with newly diagnosed BECTs who visited the Clinic during the periods from October 2012 to May 2014 before the medications against epilepsy and 41 healthy controls recruited from regular school in Beijing during the period from July 2013 to March 2014, who matched in age and gender underwent battery testing by computerized cognitive testing in epilepsy (CCTE). The BECTs group included 41 children, 20 boys and 21 girls, mean age (8.2 ± 1.7) years, the age of onset of epilepsy 4.5-11.5 years (the age of onset <8 years in 25 cases, ≥ 8 years in 16 cases). The cognitive characteristics and associated factors were analyzed. The primary data including correct answer numbers and reaction times were analyzed by independent sample t-test between the two groups of children with BECTs and healthy controls based on SPSS 18.0 statistical software.

RESULTRaw data of 9 tasks' scores collected from BECTs and healthy control children were continuous variables in accordance with normal distribution. BECTs children performed significantly worse than controls in choice reaction time ((618+158) vs. (524+254) ms), three-dimensional mental rotation (11 ± 10 vs. 18 ± 12) and visual tracing (10 ± 6 vs.15 ± 6), t=2.01, 3.03 and 3.47, P<0.05, <0.01 and <0.001, respectively.While other 6 tasks showed no significant difference between the two groups (P>0.05 for all comparisons). BECTs boys performed significantly worse than girls on simple substraction tasks compared with standard nine score ((4.7 ± 1.5) vs. (5.6 ± 1.2), t=-2.24, P<0.05). Other 8 tasks showed no significant difference between boys and girls (P>0.05 for all comparisons). Other 9 tasks showed no significant differences between the two groups of BECTs children whose age of onset was before 8 years and those who started seizure ≥ 8 years (P all >0.05). The standard nine scores of simple substraction from the three BECTs groups of dominance sides of spikes and waves during NREM showed significant difference (P<0.05). BECTs children with bilateral discharges performed significantly worse than the other two groups dominantly right or left discharges (4.7 ± 1.2 vs. 6.0 ± 1.2 vs. 4.9 ± 1.4, P all <0.05). There was no significant difference between the two groups with right and left side dominance discharges (P>0.05). Other 8 tasks showed no significant differences among the three groups (P>0.05 for all comparisons).

CONCLUSIONAlthough EEG discharges index below 50% during NREM period, while newly diagnosed BECTs children before treatment with medications against epilepsy performed poorer on tasks of choice reaction time, three-dimensional mental rotation, and visual tracing. The two factors of male and bilateral discharges during NREM period correlate with dysfunction of simple subtraction, the mechanism needs further study and the cognitive function of epilepsy children should be evaluated and followed up, in order to provide psychologic baseline data for persistent cognitive disturbance.

BACKGROUND: With social development, the average life span is prolonged. The issue of aging has increasingly attracted people's attention. It is necessary to promote the health status and the guality of life of the elderly..OBJECTIVE: To understand the status and distribution features of several common diseases which influence the quality of life of elderly.DESIGN: Random cluster sampling methods and a cross-section survey.SETTING: Beijing Institute of Geriatrics of Beijing Hospital.PARTICIPANTS:Totally 1 558 old people aged ≥60 years living in 10 communities affiliated to Jianguomen district office of the Eastern District of Beijing City,and 8 villages affiliated to Xiangyang and Henan Villagers'Commissions of Shunyi County of Beijing from May 1997 and October 1997 were recruited.In fact,1 434 persons responded,with a response rate being 92％,319 males and 498 females came from the city;242 males and 375 females came from the villages.METHODS:Questionnaires were filled up,and physical examinations were conducted in all the elderly. MAIN OUTCOME MEASURES: The 6 common diseases were observed among the elderly: Hyperplasia of prostate, abnormal audition, cartaract ,osteoarthritis, fracture and constipation.RESULTS:Totally 1434 elderly entered the stage of result analysis.①The incidence of hyperplasia of prostate in the males from the urban areas was lower than that in the rural areas (61.4％,65.7％, P ＜ 0.01 ). ② The incidence of abnormal audition among the elderly from the urban areas was lower than that in the rural areas (53.9％,64.7％,P ＜ 0.01).③ The incidence of cataract of the two eyes in the elderly from the urban areas was higher than that in the rural areas(46.4％,44.4％, P ＜ 0.01). ④ The incidence of osteoarthropathy in the elderly from the urban areas was higher than that in the rural areas (24.4％,14.9, P ＜ 0.01). ⑤ The incidence of fracture in the elderly from the urban areas was higher than that in the rural areas (14.2％,9.1％, P ＜ 0.05). ⑥ The incidence of constipation of the elderly in urban areas was lower than that in the rural areas(18.2％,23.0％,P ＜ 0.05).CONCLUSION:There is a difference between the elderly from the urban areas and the rural areas in hyperplasis of prostate,abnormal audition, cataract, osteoarthropathy, fracture and constipation, and this is related with the economy, nutrition, medical conditions and cultural traits.Therefore, attention should be attached to nutrition and health knowledge of the elderly and prevention and treatment of common diseases among the elderly people.

Objective:To explore the predictive value of high frequency ultrasound and contrast-enhanced imaging features in predicting cervical lymph node metastasis of papillary thyroid microcarcinoma (PTMC).Methods:A retrospective analysis of 184 patients with PTMC confirmed by surgery and pathology in the First Hospital of Shanxi Medical University from March 2015 to December 2018 was performed. According to the presence or absence of lymph node metastasis, the patients were divided into metastasis group and non-metastasis group. Univariate analysis was used to compare the features of high frequency ultrasound and contrast-enhanced ultrasound in the two groups, and multivariate regression analysis was used to determine the independent risk factors of cervical lymph node metastasis, and their prediction value was analyzed with ROC curves.Results:Among 184 patients, 50 (27.2%) had lymph node metastasis. Univariate analysis showed that age (χ 2=10.026) , number of nodules (χ 2=10.497) , calcification (χ 2=17.414) , aspect ratio (χ 2=4.564) , nodule location (χ 2=20.542) , enhancement time (χ 2=7.882) , enhancement mode (χ 2=6.416) and enhancement intensity (χ 2=9.899) were significantly associated with cervical lymph mode metastasis (all P<0.05). Multivariate analysis showed that age<45 years old ( OR=2.626, 95 %CI:1.141-6.052) , multifocal lesions ( OR=3.648, 95 %CI:1.542-8.631) , microcalcification ( OR=2.925, 95 %CI:1.055-8.115) and equal/high enhancement ( OR=8.042, 95 %CI: 1.879-34.429) were independent risk factors for lymph node metastasis ( P<0.05). The area under the ROC curve of above indicators combined was 0.762. Conclusions:High frequency ultrasonography combined with contrast-enhanced imaging can provide useful information for predicting cervical lymph node metastasis of PTMC. For PTMC patients aged<45 years with multifocal lesions, microcalcification and equal/high enhancement, the risk of cervical lymph node metastasis is significantly increased.
