Objective To investigate the role and the mechanism of ppk1 gene (coding for polyphosphate kinase 1) in oxidative stress resistance in uropathogenic Escherichia coli (UPEC).MethodsMutant strains with ppk1-deletion (△pk1) and complemented strains (△pk1-C) were constructed based on the UPEC strain CFT073.A comparative analysis was conducted to analyze survival rates of CFT073, △pk1 and △pk1-C strains at different time points while they were under oxidative stress.Differences in protein expression between CFT073 and △pk1 strains were analyzed using mass spectrometric analysis.Differences between CFT073 and △pk1 strains in expression of katG and katE genes were analyzed using real-time quantitative RT-PCR.Results The survival rate of △pk1 strains was lower than that of CFT073 strains at every time point, while the survival rate of △pk1-C strains was basically the same as that of CFT073 strains.Gel image analysis and mass spectrometric analysis revealed that six proteins were down-regulated and one was up-regulated in △pk1 strains as compared with those in CFT073 strains.Expression of the catalase-coding genes katG and katE in △pk1 strains were respectively (20.5±8.2)% and (20.9±6.9)% of those in CFT073 strains (P<0.05).Conclusion The ppk1 gene plays an important role in oxidative stress resistance in UPEC by modulating the expression of catalase-coding genes katG and katE.

Digital therapeutics(DTs)refers to a non-drug intervention method that uses electronic devices such as computers,smartphones,and wearable devices to evaluate and intervene through software programs and Internet technologies.It has been confirmed that there is a good therapeutic effect on a variety of mental disorders.Digital therapeutics can improve the insomnia problems of insomniacs,enhance the attention and work memory ability of patients with attention deficit hyperactivity disorder,and can also alleviate symptoms such as depression and anxiety disorder.Digital therapy will develop towards personalized treatment,popular treatment,fragmented treatment,and entertainment treatment in the future and have broad development prospects.

OBJECTIVE:
To analyze the clinical phenotypes and genetic variants of a Chinese pedigree affected with Hereditary coagulation factor Ⅻ (FⅫ) deficiency.
METHODS:
A pedigree presented at the First Affiliated Hospital of Air Force Medical University on December 24,2021 was selected as the study subject. Activated partial thromboplastin time (APTT) and coagulation factor Ⅻ activity (FⅫ:C) were determine by a clotting method, and FⅫ antigen was detected with an ELISA assay. Following the extraction of genomic DNA, all exons and flanking regions of the F12 gene were subjected to Sanger sequencing. Clustalx-2.1-win, PROVEAN and Swiss-PDB Viewer software was used to analyze the conservation of amino acids at the variant sites, impact of of the variants on the amino acid substitutions and the protein structure.
RESULTS:
The APTT of the proband has prolonged to 70.2 s. Her FⅫ:C and FⅫ:Ag have decreased to 12% and 13%, respectively. DNA sequencing revealed that the proband has harbored c.346G>A (p.Gly97Ser) and c.1583C>A (p.Ser509Tyr) heterozygous compound missense variants in exons 5 and 13 of the F12 gene, respectively. Her father and sister were heterozygous carriers for the c.346G>A (p.Gly97Ser) variant, whilst her mother and brother were heterozygous for the c.1583C>A (p.Ser509Tyr) variant.
CONCLUSION
The c.346G>A (p.Gly97Ser) and c.1583C>A (p.Ser509Tyr) compound heterozygous variants of the F12 gene probably underlay the pathogenesis of hereditary coagulation FⅫ deficiency in this pedigree.

Private health insurance(PHI)is an important component of China's multi-tiered medical security system,meeting people's multi-level and diversified health needs through supplementing and connecting with the basic medical insurance(BMI).It aims to draw on the practical experience of typical countries to provide implications for developing PHI that complements BMI in China.Considering the different models of medical security systems in various countries and the diverse functional positioning of PHI,France,Germany,Australia,the United Kingdom,and the United States are selected as reference objects.After examining the macro institutional systems of PHI,coverage population,benefits packages,characteristics of coordination with health care and medicines,as well as supporting regulatory measures,the experiences are summarized.Based on China's context,it proposes to improve institutional system building,enrich product supply,expand the insured population,explore the coverage list formulation,and refine supporting regulatory policies.
