Recently,the prevalence of human papillomavirus(HPV)infection in head and neck squa-mous cancers has shown an upward trend,especially in the oropharynx squamous carcinoma. This subset of head and neck cancers possesses distinct clinical and laboratory features and outcome,and is particulary com-mon in individuals who lack the traditional risk factors of tobacco and alcohol abuse. The biological markers and treatment of HPV associated head neck cancers are hot topic in current international research.

Background Myocarditis is a common,potentially life-threatening disease that presents a wide rang of symptoms in children,as an important underlying etiology of other myocardial diseases such as dilated and arrhythmogenic right ventricular cardiomyopathy.The incidence of nonfatal myocarditis is probably greater than that of the one actually diagnosed,which is the result of the challenges of establishing the diagnosis in standard clinical settings.Currently,no single clinical or imaging finding confirms the diagnosis of myocarditis with absolute certainty.Historically,clinical exam,electrocardiogram (ECG),serology and echocardiography had an unsatisfactory diagnostic accuracy in myocarditis.Endomyocardial biopsy remains as a widely accepted standard,but may not be suitable for every patient,especially for those with less severe disease.Our aim was to find the changes in cardiovascular magnetic resonance (CMR) imaging of children with myocarditis diagnosed by clinical criteria.Methods We studied 25 children (18 male,7 female; aged from 5-17 years) with diagnosed myocarditis by clinical criteria.CMR included function analyses,T2-weighted imaging,T1-weighted imaging before and after i.v.gadolinium injection (early gadolinium enhancement (EGE) and late gadolinium enhancement (LGE)).Results The T2 ratio was elevated in 21 children (84％,11 in anterolateral (44％),5 in inferolateral (20％),and 5 in septum (20％)),EGE was present in 9 children (36％,3 in anterolateral (12％),4 in inferolateral (20％),and 2 in septum (8％)),and LGE was present in 5 children (20％,2 in anterolateral (8％),1 in inferolateral (4％),1 in septum (4％),and 1 in midwall of left ventricular (LV) wall).In 9 children (36％),two (or more) out of three sequences (T2,EGE,LGE) were abnormal.Conclusions The CMR findings in children with clinically diagnosed myocarditis vary within the groups,including regional or global myocardial signal increase in T2-weighted images,EGE and LGE in T1-weighted images.The T2 ratio elevation is the most common CMR finding.Children with mild cardiac symptoms may also appear serious myocardial injuries.

Objective Toinvestigatestatistically significant peptide peaks as biomarkersto diagnose osteoarticular tuberculosis, matrix-assisted laser desorption/ ionization time of flight mass spectrometry (MALDI-TOF MS) was applied to identify the characteristic fingerprint among the serum of patients with osteoarticular tuberculosis, rheumatoid arthritis and healthy adults.Methods Clinical Study. Serum samples of untreatedpatients with osteoarticular tuberculosis and rheumatoid arthritis were collected from August 2018 to December 2018, and serum samples of healthy adults from physical examination were collected as control. After analysis with MALDI-TOF MS, the serum peptide fingerprint datawas imported into software, and protein polypeptide peaks with obvious differences were screened to establish diagnostic models.Results Established the diagnostic model of osteoarticular tuberculosis and healthy adults with m/z 2943.9, 5929.6, 7615.4 and 9033.8 as differential protein polypeptides, the diagnostic model of osteoarticular tuberculosis and rheumatoid arthritis with m/z 4195.6, 5847.6, 5929.6 and 7748.6 as differential protein polypeptides. To these two models, the sensitivity were 95.00％ and 97.50％, respectively. The specificity were 85.71％ and 88.46％, respectively. The accuracy rates were 89.58％ and 92.39％, respectively. The AUC value of ROC curves were 0.8859 and 0.8709, respectively. Conclusions By mass spectrometry and software analysis, the serum protein polypeptides with statistical difference were found successfully. The related diagnostic modelsarealso established, which has certain reference value for auxiliary diagnosis of osteoarticular tuberculosis.

Objective:To study the non-target metabolomics analysis and to analyze the metabolomic changesof cerebrospinal fluid (CSF) in patients with tuberculous meningitis.Methods:Case-control study. From July 2018 to July 2019, 20 cerebrospinal fluid specimens of diagnosed patients with tuberculous meningitis were collectedin the department of neurology from the first medical center of the PLA general hospital and the eighth medical center of the PLA general hospital and 20 CSF without tuberculous meningitis as the control. Among them, there were 12 males and 8 femalesin the tuberculous meningitis group, aged (37.9±16.1) years; there were 13 males and 7 femalesin the control group, aged (34.7±14.8) years. Using ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS) technology with three different mode, namely reverse phase chromatography positive ion mode, reverse phase chromatography negative ion mode and hydrophilic chromatography positive ion mode,to detectthe metabolic fingerprints of patients′CSF and analyzed by SIMCA software for orthogonal partial least squares discriminant analysis (OPLS-DA). The variable importance projection value of OPLS-DA model (threshold value>1) plus the P value of t-test (P<0.05) was applied to find the differential metabolites in the cerebrospinal fluid of the two groups of patients.Results:Ten differential metabolites were found in CSF, including L-isoleucine, L-phenylalanine, L-kynurenine, L-methionine, L-tyrosine acid, dimethylglycine, L-alanine, L-threonine, L-histidine and L-lysine, and all of them were up-regulated in the tuberculous meningitis group.Conclusion:Changesof the amino acid metabolism found in the cerebrospinal fluid of tuberculous meningitis patients can provide basis for differential diagnosis and basic molecular research of tuberculous meningitis.

BACKGROUNDMyocarditis is a common, potentially life-threatening disease that presents a wide rang of symptoms in children, as an important underlying etiology of other myocardial diseases such as dilated and arrhythmogenic right ventricular cardiomyopathy. The incidence of nonfatal myocarditis is probably greater than that of the one actually diagnosed, which is the result of the challenges of establishing the diagnosis in standard clinical settings. Currently, no single clinical or imaging finding confirms the diagnosis of myocarditis with absolute certainty. Historically, clinical exam, electrocardiogram (ECG), serology and echocardiography had an unsatisfactory diagnostic accuracy in myocarditis. Endomyocardial biopsy remains as a widely accepted standard, but may not be suitable for every patient, especially for those with less severe disease. Our aim was to find the changes in cardiovascular magnetic resonance (CMR) imaging of children with myocarditis diagnosed by clinical criteria.

METHODSWe studied 25 children (18 male, 7 female; aged from 5-17 years) with diagnosed myocarditis by clinical criteria. CMR included function analyses, T2-weighted imaging, T1-weighted imaging before and after i.v. gadolinium injection (early gadolinium enhancement (EGE) and late gadolinium enhancement (LGE)).

RESULTSThe T2 ratio was elevated in 21 children (84%, 11 in anterolateral (44%), 5 in inferolateral (20%), and 5 in septum (20%)), EGE was present in 9 children (36%, 3 in anterolateral (12%), 4 in inferolateral (20%), and 2 in septum (8%)), and LGE was present in 5 children (20%, 2 in anterolateral (8%), 1 in inferolateral (4%), 1 in septum (4%), and 1 in midwall of left ventricular (LV) wall). In 9 children (36%), two (or more) out of three sequences (T2, EGE, LGE) were abnormal.

CONCLUSIONSThe CMR findings in children with clinically diagnosed myocarditis vary within the groups, including regional or global myocardial signal increase in T2-weighted images, EGE and LGE in T1-weighted images. The T2 ratio elevation is the most common CMR finding. Children with mild cardiac symptoms may also appear serious myocardial injuries.
