Objective:To analyse the clinical characteristics of 214 cases of paediatric high altitude pulmonary edema（HAPE）and the efficacy of dexamethasone in adjunctive therapy.Methods:This retrospective study analyzed 214 pediatric cases of HAPE admitted to the Department of Paediatrics of the General Hospital of Tibetan Military between June 2015 to June 2017 and June 2019 to June 2021.Patients were divided into dexamethasone-treated group and dexamethasone-untreated group.Baseline data，clinical characteristics were collected to evaluate the treatment efficacy and drug side effects.Results:There were 107 children in each of the two groups with a median age of 8（5，11）years. The median age of the dexamethasone-treated group was 9（6，12）years and the mean age of the dexamethasone-untreated group was 7（3，10）years. The proportion of male children was 69.60%（149/214）；the onset of illness was mostly concentrated within 72 hours，accounting for 97.20%（208/214）of the cases；83.18%（178/214）of the cases had symptoms of combined upper respiratory tract infection before entering the plateau. The most important clinical symptoms of the children were cough（86.92%，186/214），cyanosis（70.09%，150/214），and shortness of breath（66.36%，142/214）. The proportion of auscultatory rhonchi was 83.18%（178/214），and all cases showed positive findings on chest radiography. After the dexamethasone regimen，the overall cure rate of the children was 94.39%，the average disappearance time of the symptoms and signs was（40.52±7.85）h，and the average hospital stay was（3.60±1.90）d. After treatment with the dexamethasone-free regimen，the overall cure rate was 92.52%，the mean time to disappearance of symptoms and signs was（42.10±7.62）h，and the mean length of stay in the hospital was(3.84±2.08)d. There was no significant difference in the cure rate，the disappearance time of symptoms and signs，and the average hospitalisation days between the two groups（ P>0.05），but a total of 11 children in the dexamethasone-treated group experienced adverse drug reactions，and no children in the dexamethasone-untreated group experienced adverse drug reactions. Conclusion:Han Chinese male children，particularly those with upper respiratory infections，should be closely monitored for HAPE risk within three days of ascending to high altitudes. This study does not recommend the use of dexamethasone for pediatric HAPE due to the lack of therapeutic benefits and potential adverse effects.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.

Emerging and re-emerging RNA viruses occasionally cause epidemics and pandemics worldwide, such as the on-going outbreak of the novel coronavirus SARS-CoV-2. Herein, we identified two potent inhibitors of human DHODH, S312 and S416, with favorable drug-likeness and pharmacokinetic profiles, which all showed broad-spectrum antiviral effects against various RNA viruses, including influenza A virus, Zika virus, Ebola virus, and particularly against SARS-CoV-2. Notably, S416 is reported to be the most potent inhibitor so far with an EC of 17 nmol/L and an SI value of 10,505.88 in infected cells. Our results are the first to validate that DHODH is an attractive host target through high antiviral efficacy in vivo and low virus replication in DHODH knock-out cells. This work demonstrates that both S312/S416 and old drugs (Leflunomide/Teriflunomide) with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide, no matter such viruses are mutated or not.

Objective To investigate the application value of the self-rated health measurement scale (SRHMS) in health check-up.Method A total of 8 083 health check-up receivers frow Fujian Province underwent SRHMS self-assessment,and the results of the assessment were analyzed by Chi-square test.Result The results of the survey showed that the total prevalence rate of chronic disease was 57.8％ top five were stomach/duodenum diseases (14.57％),hypertension (11.58％),mammary gland disease (8.04％),abnormal blood lipid (7.16％) and prostate disease (6.54％).The proportion of these five kinds of illness was 43.38％.A positive correlation between the prevalence rate of chronic disease and age was found.The difference of the prevalence rate of chronic diseases between each age group was statistically significant (x2=863.816,P=0.000).Those with family history of chronic diseases accounted for 69.27％ and those with history of present illness accounted for 57.83％ (4 674/8 083).Bodily pain,dietary preferences,refined grain intake,lack of exercise,and alcohol drinking was found in 75.03％,60.15％,54.84％,46.07％ and 41.50％ participants.Conclusion The SRHMS could reflect the chronic disease incidence and unhealthy daily habits.

Objective To develop a conceptual framework for the synopsis of information of health examination reports (HERs) and its style sheet so as to provide a reference for information collection and management in health examination institutions.Methods A conceptual framework for the synopsis of information of HERs and its core data elements were developed based on HERs items from 11 health examination institutions,and a style sheet for the synopsis of information of HERs was then designed.Results The conceptual framework included 4 dimensions (e.g.identification information,health-related information,health exam summary,health evaluation and guidance),16 sub-dimensions,52 core data elements and 25 value domains.The structure and content of the designed sheet were consistent with the dimensions,subdimensions and core data elements of the conceptual framework.Conclusions The developed synopsis of information of HERs could be a feasible solution for structured and standardized representation of clients' health examination information.The selection and filling of some items should be validated and refined in the future.

Many studies have shown that chronic inflammation occurs in the brain of patients with Alzheimer's disease (AD). It is well known that long-term administration of non-steroidal anti-inflammatory drugs (NSAIDs) can alleviate the cognitive decline of AD patient and elderly. Several inflammatory cytokines produced in the metabolism of arachidonic acid (AA) are closely related to inflammatory diseases. Lipoxygenases (LOXs) and cyclooxygenases (COXs) play a crucial role in the AA network, the products eicosanoids have an important impact on the progression of AD. Although there are many arguments and conflicting evidence, currently LOXs and COXs are still the hot topics in the research on AD pathogenesis and drug development. Here, we review the progress in research on COXs and LOXs, including their actions on CNS and their association with AD, and explore the feasibility of LOXs and COXs as targets for the drugs to prevent and/or treat AD.
