BACKGROUND: Previous evidence showed that ambient air pollution and cardiovascular mortality are related. However, there is a lack of evidence towards the modification effect of long-term lifestyle on the association between short-term ambient air pollution and death from cardiovascular events. METHOD: A total of 14,609 death from major adverse cardiovascular events (MACE) were identified among the China Kadoorie Biobank participants from 2013 to 2018. Ambient air pollution exposure including particulate matter 2.5 (PM_2.5), SO₂, NO₂, CO, and O₃ from the same period were obtained from space-time model reconstructions based on remote sensing data. Case-crossover design and conditional logistic regression was applied to estimate the effect of short-term exposure to air pollutants on MACE mortality. RESULTS: We found MACE mortality was significantly associated with PM_2.5 (relative percent increase 2.91% per 10 µg/m³ increase, 95% CI 1.32-4.53), NO₂ (5.37% per 10 µg/m³ increase, 95% CI 1.56-9.33), SO₂ (6.82% per 10 µg/m³ increase, 95% CI 2.99-10.80), and CO (2.24% per 0.1 mg/m³ increase, 95% CI 1.02-3.48). Stratified analyses indicated that drinking was associated with elevated risk of MACE mortality with NO₂ and SO₂ exposure; physical inactivity was associated with higher risk of death from MACE when exposed to PM_2.5; and people who had balanced diet had lower risk of MACE mortality when exposed to CO and NO₂. CONCLUSIONS The study results showed that short-term exposure to ambient PM_2.5, NO₂, SO₂, and CO would aggravate the risk of cardiovascular mortality, yet healthy lifestyle conduct might mitigate such negative impact to some extent.

Multimodal fusion research in traditional Chinese medicine （TCM） inspection has greatly improved the accuracy of identification results with the help of emerging technologies in science and technology. At present， multimodal fusion technology is used in the integration of the parameters collected by the inspection instruments and the analysis of the parameters， which is represented by the development and application of the tongue inspection instrument， the face inspection instrument and the eye inspection instrument. However， the multimodal fusion research of TCM inspection has problems such as insufficient comprehensiveness and accuracy of parameter acquisition， difficulty in parameter integration for fusion analysis， and low clinical practicability of identification results. It is believed that， while keeping up with the cutting-edge science and technology， research on multimodal fusion of TCM inspection should be guided by the holism concept of TCM， and should focus on the enhancement of comprehensiveness and accuracy of multimodal parameter acquisition， standardisation of parameter fusion， and fusion of identification results， so as to gradually promote the objectivity， intelligence and modernisation of the four diagnostic methods of TCM.

China prospective multicenter birth cohort (Prospective Omics Health Atlas birth cohort, POHA birth cohort) study was officially launched in 2022. This study, in collaboration with 12 participating units, aims to establish a high-quality, multidimensional cohort comprising 20 000 naturally conceived families and assisted reproductive families. The study involves long-term follow-up of parents and offspring, with corresponding biological samples collected at key time points. Through multi-omics testing and analysis, the study aims to conduct multi-omics big data research across the entire maternal and infant life cycle. The goal is to identify new biomarkers for maternal and infant diseases and provide scientific evidence for risk prediction related to maternal diseases and neonatal health.

The vast majority of patients with hepatocellular carcinoma (HCC) in China originate from hepatitis B cirrhosis, while 90% of cirrhotic patients may develop portal hypertension, and the HCC patients with portal hypertension account for 15%-30%. Portal hypertension is a group of clinical syndromes characterized by elevated portal venous pressure and formation of portal-systemic collateral circulation, and it is one of the most important complications of liver cirrhosis. HCC and portal hypertension affect each other, and portal hypertension seriously affects the prognosis of HCC patients. The development of systemic treatment regimens for HCC provides more treatment options for patients with advanced HCC, including molecular-targeted drug therapy, immunotherapy, and chemotherapy. Different systemic therapeutic drugs for HCC have different impacts on portal hypertension, and this article reviews the effect of commonly used systemic therapeutic drugs for HCC on portal hypertension.

Objective: To understand the present situation of physical activity and its influencing factors, and to provide a reference for improving the level of physical activity and making the intervention measures. Methods: The method of random stratification was used to select 4 740 pre school children aged 3-6 from 17 kindergartens in 12 counties and districts of Nanchang City, The questionnaire of physical activities of young children and the questionnaire of parents of physical activities of young children were applied to conduct a survey. Results: Compared with weekday PA and MVPA, preschool children’s weekends decreased, SB increased. The differences in PA, MVPA and SB on weekdays and weekends were statistically significant( P <0.01). The proportion of PA and MVPA reaching the recommended amount during the working day of preschool children were 44.9%-59.2%, 45.4%- 61.7%.The proportion reaching the recommended amount of PA and MVPA on weekends were 24.7%-27.8%, 24.5%-29.9%, and the proportion reaching the recommended amount on weekdays was higher than that on weekends. Conclusion There is still gap between actual amount of physical activity and the recommended amount. There are different modes of activity on weekdays and weekends, and weekends are the least active periods. Parents and teachers should pay enough attention to the establishment of "social campus family" model to improve the lack of physical activity of preschool children.

Objective: To analyze the occurrence features of adverse events following immunization (AEFI) of Seasonal Influenza Vaccines (InfV) used in China, 2015-2018 influenza season. Methods: InfV (including concurrent administered with other vaccines) AEFI data were collected through the Chinese national AEFI information system during 2015.9.1-2018.8.31 (excluding Chinese Hong Kong, Macao and Taiwan data). The vaccine lot release data were collected from National Institutes for Food and Drug Control published database. Time periods of three influenza season were 2015.9.1-2016.8.31, 2016.9.1-2017.8.31, 2017.9.1-2018.8.31. The vaccines used and included in this analysis were trivalent inactivated influenza vaccine (IIV3)-Split, IIV3-Split (Children) and IIV-subnit. The incidence of AEFI were calculated (per 100 000 release doses), and epidemiological characteristic were analyzed using descriptive methodology. Results: A total of 8 464 InfV AEFIs were collected in 2015-2018 influenza season from National AEFI Information System, in which 5 646 were IIV3-split, with the rate of 10.64/100 000 release doses, 2 818 were IIV3-split (Children), with the rate of 9.355/100 000 release doses. The most common symptom was fever (axillary temperature ≥37.1 ℃) within vaccine reactions, with a number of 6 207 cases. In which, there were 3 554 cases with fever (axillary temperature ≥38.6 ℃) and the estimated reporting rate was 4.274/100 000 release doses. In all rare vaccine reactions, the most common diagnosis was anaphylactic rash(442, 0.531/100 000 release doses) and angioedema (70, 0.084/100 000 release doses). Even the rates of serious rare vaccine reactions were low, febrile Convulsion (27, 0.032/100 000 release doses) and Henoch-Schönlein Purpura(HSP) (21, 0.025/100 000 release doses) were relatively common in serious rare vaccine reactions during the study period. Conclusion The estimated rate of rare vaccine reactions related toInfV was relatively low. In all vaccine reactions, fever was the most common symptoms. The most common diagnosis of non-serious rare vaccine reaction were anaphylactic rash and angioedema. The incidence of serious rare vaccine reactions was low.

The effects of microRNA-34a (miR-34a)-regulated Notch1 gene on the proliferation and apoptosis of the human glioma cell line U87 were investigated in this study. The U87 cells were divided into miR-34a mimics, negative control, mock transfection and blank control groups in terms of different treatments. In miR-34a mimics group, human U87 glioma cells were transfected with miR-34a mimics by using lipofectamine 2000. The cells transfected with nonsense microRNA were set up as negative control group. Those treated with lipofectamine 2000 only were designated to the mock tranfection group. In the blank control group, the cells were cultured routinely and no treatment was given. The expression of miR-34a and Notch1 was detected by using real-time RT-PCR. Western blotting was employed to monitor the change in Notch1 protein. Cell proliferation and apoptosis were measured by CCK-8 and flow cytometry. The results showed that the proliferative ability of U87 cells was significantly reduced and the apoptotic cells increased in miR-34a mimics group relative to control groups. The expression of miR-34a was significantly up-regulated in mimics group as compared with control groups (P<0.05). Furthermore, Notch1 protein levels were significantly decreased in miR-34a mimics group when compared with control groups (P<0.05), but the mRNA expression of Notch1 showed no significant difference among these groups. It was concluded that miR-34a may suppress the proliferation and induce apoptosis of U87 cells by decreasing the expression of target gene Notch1, suggesting that miR-34a may become a promising gene therapeutic target for brain glioma.
