Objective　To analyze the current status of influenza in Inner Mongolia Autonomous Region and provide targeted measures for the prevention and control of influenza in the entire region. Methods　We collected data on influenza cases reported in Inner Mongolia Autonomous Region from the "Disease Monitoring Information Report Management System" of the China Disease Prevention and Control Information System from 2018 to 2022. Statistical analysis was performed using IBM SPSS 22.0, and the comparative differences were assessed using the χ2 test. ArcGIS 10.5 was used to create thematic maps. In this study, SaTScan 9.5 was used for spatiotemporal scanning analysis of influenza incidence data in the entire region from 2018 to 2022, conducting retrospective spatiotemporal reordering scans. Results From 2018 to 2022, a total of 25 485 cases of influenza were documented in Inner Mongolia, with the highest number of cases reported in 2019 (9 933 cases). Cases were reported throughout the year, with a peak season occurring in the winter and early spring of the following year. There were 13 538 cases in males and 11 947 cases in females, with a male-to-female ratio of 1.13:1, indicating a higher incidence rate in males. Cases were mainly concentrated in individuals under the age of 20, especially in the age group of 0 to 10 years, There were significant differences in influenza incidence rates among different regions and years, showing alternate patterns of prevalence. Retrospective spatiotemporal scanning analysis of influenza cases in Inner Mongolia Autonomous Region from 2018 to 2022 revealed that, in terms of temporal distribution, the cluster of cases mainly occurred in November to December each year and in January of the following year. During the influenza season, cases exhibited significant spatiotemporal clustering in the region. Conclusions　The number of reported influenza cases in Inner Mongolia Autonomous Region varied from year to year but there was no increasing trend over time. Children under 10 years old were the primary susceptible population, and influenza exhibited significant seasonal variation and spatiotemporal clustering. It is recommended to strengthen public awareness and education on influenza prevention and vaccination before the influenza season each year, develop good hygiene habits, seek medical attention early when symptoms occur, and reduce the risk of clustered influenza outbreaks.

The contents of schisandrin, schizandrin A, B and C were determined by HPLC, and the effects of the climate factors and altitude on lignin contents were analyzed in order to select the optimal cultivation area of S. chinensis. The lignin contents were analyzed by HPLC using a ZORBAX SB-C18 column (4.6 mm x 250 mm, 5 microm). The column temperature and detection wave length were set at 35 degrees C and 254 nm, respectively. Methanol-water was used as the mobile phase in gradient elution mode and the flow-rate was 1.0 mL min(-1). The method had a good repeatability, stability and accuracy. The correlation of climate factors and lignins contents was analyzed by SPSS software. The results showed that the schizandrin A content in S. chinensis fruits were higher than 0.4% in Ji'an, Liuhe, Antu and Fusong in Jilin province, which met the quality requirement. It had significant linear negative correlation relationship between schisandrin, schizandrin A, B and altitude, the contents decreased with the increase of altitude. The significant negative linear fitting coefficient was 0.844 1 between schisandrin and altitude; but it had not significant correlation between schizandrin C and altitude. A significant positive correlation of climate factors and the contents of S. chinensis lignins were mainly the temperature factors (the average annual temperature, the highest temperature in July, the average temperature in July, the highest temperature in January, the average temperature in January) and precipitation factor (average annual precipitation), which reveals that higher temperature and precipitation were helpful to the formation and accumulation of lignins of S. chinensis. So the cultivation area of S. chinensis should be in the low elevations region with warm and rainy climate.

Objective: To acquire recombinant nematode anticoagulant peptide ( NAP) with high anticoagulant activity. Methods: Pichia pastoris GS115 strain was transformed with recombinant yeast expression vector pPICS. 5K-rNAP. Expression of rNAP was induced with methanol after the identification of positive strains. NAP expressed in the collected yeast culture supernatant was confirmed with SDS-PAGE and Western blot. The biological activity of the products was validated with PT (prothrombin time) , INR (international normalized ratio) and APTT (activated partial thromboplastin time) , respectively. Results: The yeast strains expressing NAP were identified. The rNAP was secreted into culture supernatant with a molecular weight of about 10 kDa due to glycosylation, which is a little bigger than that predicted (8.7kDa). The anticoagulant efficiency of rNAP was confirmed with the in vitro assays. Conclusion: The recombinant nematode anticoagulant peptide with high biological activity was successfully expressed in Pichia pastoris and can be used in the future development of novel anticoagulant agent.

Objective To investigate the effects of Helicobacter priori (H.prlori) strains from the patient with gastric cancer on the expression of DNA mismatch repair (MMR) genes in AGS cells in vitro. Methods AGS cells were co-cultured with ten strains of H.prlori from five patients with gastric cancer and five patients with gastritis respectively.The expressions of DNA MMR genes (hMSH2 and hMLH1) in mRNA and protein levels were determined by RT-PCR and Western blot.The enteropathogenic E.coli served as a bacterial control.Results E.coli and H.priori strains from gastritis have no effects on the expression of hMSH2 and hMLH1 in both protein and mRNA levels on the whole,while all the H.prlori strains from gastric cancer reduced expression levels of hMSH2 and hMLH1.Conclusions There are different effects between H. prlori strains from gastric cancer and those from gastritis on DNA MMR in AGS cell line,indicating that infec- tion of some H.prlori strains might lead to the inhibition of DNA MMR,and that in turns increases the risk of gastric carcinogenesis during chronic H.prlori infection.
