Objective To study the expression of HIF-1αand and its correlation with gastric cancer recurrence, and to identify its prog-nosis evaluation in gastric cancer recurrence. Methods 80 patients with gastric cancer recurrence after radical surgery were selected as the observation group, and 50 patients without gastric cancer recurrence 5 or more than 5 years after surgery were selected as the control group. The immunohistochemical situation and expression of VEGF of the two groups were compared, and the correlation of HIF-1αand VEGF and gastric cancer recurrence were analyzed. Results The positive expression rate of HIF-1αand VEGF were 77. 50% and 73. 75% respectively in the observation group, which were significantly higher than 12. 00% and 10. 00% in the control group. Univariate analysis showed that the related indices such as degree of differentiation, depth of invasion, lymph node metastasis, vascular invasion, and TNM clinical stage were associated with VEGF expression and positive expression of HIF-1α. The Spearman correlation analysis showed that HIF-1α and VEGF was positively correlated (r=0. 458,P=0. 000). 1-year survival rate of HIF-1α-positive group was 45. 16%, and the average survival time was (8. 62 ± 2. 32) months, which was significantly lower than 77. 77% and (18. 96 ± 3. 14) months respectively in the negative group. Cox risk model analysis showed that HIF-1αand VEGF expression were high risk factors for gastric cancer recurrence. Conclusion HIF-1αand VEGF expression have a very colse correlation with gastric cancer recurrence, and it can be used as evaluation of gastric cancer recurrence and prognosis.

Abstract: Objective To analyze the causes of foodborne illness outbreaks in Inner Mongolia, so as to provide reference for understanding systemic risks and formulating prevention and control measures. Methods Data on foodborne disease outbreaks in Inner Mongolia Autonomous Region from 2016 to 2021 were collected through the "Foodborne Disease Outbreak Monitoring System" for attribution analysis. Results A total of 591 outbreak events were included from 2016 to 2021. Single -dimensional attribution analysis showed that the main causes of foodborne disease outbreaks in this region were vegetables and vegetable products, and meat and meat products, respectively accounting for 20.5% (121/591) and 12.6% (75/591) of the total events. leading contributing factor was improper processing, accounting for 16.2%(96/591), and the main pathogenic factor was toxic plants and their toxins, accounting for 14.9%(88/591). Multi-dimensional attribution analysis showed that the highest number of outbreak events occurred in summer, with 290 cases accounting for 49.1% (290/591) of the total number of events. The eastern, central, and western regions also had the highest number of events in summer, accounting for 53.6% (180/336), 39.5% (60/152), and 48.5% (50/103) of the total number of events in this region, respectively. Among vegetables and vegetable products, improper processing led to the majority of outbreaks caused by toxic plants and their toxins, accounting for 58.7% (71/121) of total events. For meat and meat products, improper storage resulting in the most outbreaks of biological pollution, accounting for 16.0%(12/75) of the total number of meat and meat product incidents. Majorities of death cases were primarily due to accidental ingestion or misuse of non-food items (such as poisonous mushrooms), comprising 38.5% (5/13) of total deaths. Conclusions The main food, triggering factors, and pathogenic factors involved in the outbreak of foodborne diseases in this region are relatively routine and controllable. Therefore, efforts should be made to strengthen public food safety education to reduce the occurrence of foodborne diseases.

Objective To observe neural stem cells proliferation,migration and differentiation in hippocampus in developing rats with status epileptictus.Methods 320 healthy SD rats at age 7,14,21,28 d (P7,P14,P21,P28) were randomly divided into status epilepticus (SE) and normal control group.In each group those rats at the same age were further randomly divided into 1,7,14,21,28 d five time points after PTZ-induced SE (n =8).New cell proliferation and migration were observed by immunohistochemistry studies in the dentate gyms.Double labeling with Brdu/NeuN and Brdu/GFAP was performed in the P14 rats.Results Nestin positive cells appeared in the dentate gyms on 1 d after SE in P7,P14,P21,P28 rats.The number of nestin positive cells gradually increased on 7 d and reached a peak on 14 d,then gradually reduced on 21 d,finally fell to a minimum on 28 d after SE.The numbers of nestin positive cells on 7 d(177.00 ± 3.22,t =16.033) and 14 d (195.00 ± 3.41,t =28.840) were significantly higher in the SE group than the NS group (147.50 ± 2.08,136.50 ± 2.65,both P ＜ 0.05).The smaller age of rats with SE onset,the greater the nestin intensity.But the number of nestin positive cells in the dentate gyrus of normal rats were gradually decreased with increasing age.Nestin positive cells were distributed in subgranular zone of dentate gyrus on 1 d and 7 d after SE,then gradually migrated to the granule cell layer on 14 d with morphological changes.Small part of nestin positive cells were ectopically migrated to the hilus of dentate gyrus in P14,P21,P28 age rats,and were also seen in the CA1,CA3 of hippocampus and cortex with various cell morphology.For differentiation of newly generated cells,most of Brdu positive cells coexpressed NeuN and about 4％-5％ cells co-expressed GFAP.Conclusions SE could induce neurogenesis in the hippocampal dentate gyrus area in developing rats which has age-related characteristics.Most new cells migrate from the subgranular zone to the granule cell layer of the dentate gyrus,and a small number of newly generated cells ectopically migrated to the hilus of dentate.The majority of newly generated cells differentiate into neurons,and the others differentiate into glial.

Objective To study the distribution and expression of Semaphorins-3A protein in brain of postnatal rats.Methods Semaphorins-3A positive cells were observed by immunohistochemistry in the cerebral cortex,hippocampus,dentate gyms and entorhinal cortex in postnatal 0d,7d,14d,21 d and 28d of Sprague Dawley rats.Results Semaphorins-3A positive cells widely distributed in the granule cell layer ( Ⅱ ),external pyramidal cell layer ( Ⅲ ),internal granular cell layer ( Ⅳ ),pyramidal cell layer ( Ⅴ ) and layer of polymorphous cells ( Ⅵ ),in addition to the molecular layer ( Ⅰ ) of the parietal,occipital,frontal,temporal,insular,cingulate cortex,piriform cortex and entorhinal cortex with postnatal 0d,7d,14d,21d and 28d rats.The amount of semaphorins-3A positive cells(IOD) in the entorhinal cortex was 84916.23 ± 3266.34 in P0d,77711.41 ± 2634.26 in P7d,74124.25 ± 3989.09 in P14d,65887.63 ± 3406.57 in P21d and 57705.96 ± 3136.35 in P28d,meanwhile the region of semaphorins-3A positive cells narrowed in the part level with Ⅱ -Ⅵ levels of cortex.Similarly semaphorins-3A positive cells distributed mainly in granule cell layer of dentate gyrus,CA1,CA3 region and only a few of semaphorins-3A positive cells scattered in the multi-line layer in hippocampus.The expression level of semaphorins-3Awas significant difference among postnatal 0d,7d,14d,21d and 28d rats (P＜0.01).Conclusion Semaphorins-3A positive cells widely distribute in the various cortex and hippocampus in developing rat brain,and the region of semaphorins-3A is reduced with age growth of rats.

ObjectiveTo observe Semaphorins-3A and synaptophysin P38 expression in hippocampus of developing rat induced by status epilepticus.Methods 320 SD rats were divided into four groups (P7,P14,P21 and P28) according to day -old after birth (7d,14d,21d and 28d).Rats in each group were randomly divided into model group (SE group) and saline control group (NS group).SE was induced by Pentylenetetrazol (PTZ).Semaphorins-3A and synaptophysin P38 expression were determined by immunohistochemical staining on 1d,7d,14d,21d and 28d after SE in hippocampal CA1 of rats.ResultsSemaphorins-3A-positive cells could be seen in the hippocampal granule cell layer in all rats.Semaphorins-3A expression tended to decrease with the increasing of day-age,especially in P7 group(91 552.68 ± 4664.69 ).No matter how day-age,Semaphorins-3A expression was similar to that in NS group and was obvious reduced in 7d after SE(56 938.84 ± 5688.47 ).Meanwhile P38 expression in P7-day-age rats had had been gradually increasing between 1 day and 14d (5413.18 ±48.77,6223.40±29.19,6902.94 ±78.51 ) and then stabilized gradually on 21d(7523.42 ± 62.94) after rats were tested.P38 expression in other day-age rat was relatively stable on the same level in physiological state.On the other hand P38 expression in the hippocampal CA1 region of P7,P14,P21 and P28 rats was significantly higher than that in normal rats between 1day and 28day after SE episode(P＜ 0.05 ),and reached a peak on 14 day(8408.35 ± 55.73 ).ConclusionSemaphorins-3A and synaptophysin P38 involved in hippocampal synaptic plasticity of rat in developing stage and epilepsy.
