Objective:A new method of measuring pulse wave velocity,double-cuff method,has been proposed based on oscillometric method and used to practice to validate its reliability in this paper.Methods:In this method,two cuffs are used to collect pulse wave signals of humerus and oar artery respectively.We analyse the two signals'time difference ?t by choosing wave boot as the pulse beating' start point.Pulse wave velocity can be calculated according to the formula PWV=?S/?t,in which ?S is the distance between humerus and oar artery and can be measured by a soft ruler.Results:The double cuff method,which has the advantages of simple operation,speedy measurement and low cost,can measure pulse wave velocity reliably,accurately,fast and simply.Conclusions:The pulse wave velocity measured by this new method,which can reflect the differences between normal people and critical or already hypertension suffers,is significant in forecasting hypertension.

Objective To investigate the distribution of pathogens in acute severe lower respiratory tract infection and drug resistance.MethodsFrom October 2014 to December 2016, selected 441 children patients with acute severe lower respiratory tract infectionin tianjinfifth centralhospital were drawn lower respiratory tract secretions from the oral endotracheal intubation of the disposable suction tube or container, bacterial culture and identification, to determine the type of bacteria, and drug susceptibility test.ResultsA total of 642pathogens were co-cultured in 441 children, of which 391 were Gram-negative bacteria, accounting for 60.90% (391/642), including Pseudomonas aeruginosa (17.45%), Acinetobacterbaumannii (14.80 %), Klebsiellapneumoniae (13.86%);Gram-positive bacteria were 150 strains, accounting for 23.36% (150/642), mainly including Staphylococcus aureus (15.58%).Gram-negative bacteria are mostly resistant bacteria and multidrug-resistant bacteria, piperacillin and imipenem resistance is relatively low.Gram-positive bacteria on penicillin, gentamicin, erythromycin and other drug resistance are high, resistance to vancomycin are low, including Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis Resistant drug resistance were 0.00%.ConclusionThe pathogens of lower respiratory tract infection in children with acute severe disease mainly include Pseudomonas aeruginosa, Acinetobacterbaumannii and Klebsiellapneumoniae and other Gram-negative bacteria, the clinical application should be based on the results of pathogen species and susceptibility test to choose reasonable antimicrobial drugs for children patients.

Posterior cortical atrophy (PCA) is a kind of neurodegenerative dementia,which is characterized by the progressive decline of visuoperceptual,visuospatial,reading and writing ability and praxic skills.Neuroimaging usually shows atrophy or metabolic decrease in posterior brain regions.The most common neuropathologic changes of PCA are amyloid plaques deposition and neurofibrillary tangles in posterior cortex.In general,PCA is considered as a variant form of Alzheimer's disease.

Serum prostate-specific antigen (PSA) is composed of the PSA precursor protein (proPSA) in the absence of the leader peptide induced by human kallikrein 2 (hK2). There are many forms of PSA in the blood, including free PSA and bound PSA. Serum proPSA, as a free PSA, has many isoforms, among which, [-2]proPSA (p2PSA) cannot be activated by hK2 and therefore exists stably in the blood. Serum p2PSA is a homologous isomer of PSA. Serum prostate health index and % p2PSA, as the derivative indexes of p2PSA and molecular markers associated with the development and progression of prostate cancer, can reduce serum PSA test-induced excessive diagnosis and treatment of the malignancy and improve the accuracy of its prediction. This review summarizes recent progress in the studies of serum p2PSA and its derivative indexes in prostate cancer.
