Objective: To investigate the prevalence and influencing factors of repeated HIV antibody tests among men who have sex with men (MSM) in Wuhan City, so as to provide insights into the development of interventions against AIDS among MSM. Methods: MSM with self-reported homosexual behaviors in a community studio in Wuhan City were recruited using a convenient sampling method from January to April 2019, and participants' demographic features, sexual behaviors, HIV antibody tests and recognition of HIV antibody tests were collected using questionnaires. Factors affecting repeated HIV antibody tests were identified using a multivariable logistic regression model. Results: Totally 300 valid questionnaires were recovered, with a mean age of (31.06±10.24) years. Among all the participants, 196 participants had the first homosexual behaviors over 18 years of age (65.33%), 107 participants were insertive partners (35.67%), and 125 participants received sex-transmitted diseases (STDs) tests in the past six months (41.67%). The mean score for recognizing the risk of HIV infection was 12.41±3.09, for HIV antibody test self-efficiency was 17.07±2.12, and for perceived social supports was 17.42±2.41. A total of 287 respondents received HIV antibody tests (95.67%), including 192 participants receiving repeated HIV antibody tests (64.00%). Multivariable logistic regression analysis showed that age of >18 years for the first homosexual sex behavior (OR=0.404, 95%CI: 0.223-0.734), receiving STDs tests in the past six months (OR=3.896, 95%CI: 2.145-7.076), sex role as receptive partners or both receptive and insertive partners (OR=0.502, 95%CI: 0.275-0.917), satisfying with HIV antibody test services (OR=2.955, 95%CI: 1.311-6.660), and high score for HIV antibody test self-efficiency (OR=1.149, 95%CI: 1.005-1.314) were factors affecting repeated HIV antibody tests among MSM. Conclusions The detection of repeated HIV antibody tests was 64.00% among MSM in Wuhan City in 2019, and age for the first homosexual behavior, STDs tests, sex role, evaluation of HIV antibody test services and self-efficiency of HIV antibody tests may be factors affecting repeated HIV antibody tests among MSM.

Objective To evaluate the diagnostic value of myeloperoxidase (MPO)in diagnosis of non-ST elevation acute cor-onary syndromes (NSTE ACS).Methods The MPO was determined in 61 unstable angina pectoris (UAP)patients and 54 non-ST-elevation myocardial infarction (NSTE MI)patients,then analyzed the data with receiver operationg characteristic curve (ROC curve)statistical software.The major adverse cardiac events (MACE)were obseved in 106 NSTE ACS patients through 1 year of follow-up.Results The MPO values of NSTE MI group and UAP group were 672±418 ng/ml and 459± 328 ng/ml,the difference was statistically significant (t=3.928,P <0.001).The cTnI values were 558±261 pg/ml and 405 ±278 pg/ml of respectively.The difference was statistically significant (t = 3.089,P = 0.003).The area under the ROC curve of MPO was 0.726 when the optimal cutoff value was 382 ng/ml in the diagnosis of NSTE MI.The sensitivity and specificity was 92.6% and 39.8%.The area under the ROC curve of cTnI was 0.799 when the optimal cutoff value was 484 ng/ml in the diagnosis of NSTE MI.The sensitivity and specificity was 65.5% and 92.3%.High MPO maintained a strong association with the risk of major adverse cardiac events through 1 year of follow-up.Conclussion MPO is ahigh sensitivity marker of the NSTE MI and of clinical value for prognosis of NSTE ACS.

Exosome is a self-secreted phospholipid bilayer nanovesicles, and has shown great potential in drug delivery field due to the important advantages of low immunogenicity and homologous targeting. Phototherapy, mainly includes photodynamic therapy (PDT) and photothermal therapy (PTT), utilize light to activate photoactive drug for tumor cell killing. The advanced therapeutic strategy shows low toxic side-effect and non-invasion precise advantages, and thus has made great progress in tumor treatment over the past few years. Therefore, using exosomes as a drug delivery system to deliver phototherapeutic agents can improve therapeutic performances with a reduced side-effect, and further enhance their application potential for clinical tumor therapy. This review focus on the rising cross-subjects field involving exosomes and phototherapy, and mainly introduce the research progress and relative case of exosomes-based delivery system for cancer phototherapy. Additionally, the advantages and challenges of exosome-based phototherapy are also discussed and proposed.

Objective To investigate the clinical and mammographic features of plasma cell mastitis.Methods Twenty-five patients(28 lesions)with histologically confirmed plasma cell mastitis, aged from 26 to 70 years(mean age 41 years),were examined with X-ray mammography.The clinical manifestations and imaging features were retrospectively reviewed.Results No case was in lactation.The painful irregular masses,ranged from 1.3 to 8cm in size,were found in 22 patients,while 3 patients with acute episode.Recurrent episodes of breast masses were noted in 4 patients.Based on the mammographic appearances,the plasma cell mastitis were classified as the following four types:inflammation-like type (2/28),ductal ectasia type(3/28),focal infiltration type(10/28)and nodular type(13/28).The valuable radiogyaphic signs:(1)An asymmetrically increased density along the lactiferous duct with a flame-like appearance,inhomogeneous low density tubular structures and scattered stick-shape calcifications.(2) Architectural distortion and oil cysts formation in adjacent area,(3)Subareolar ductal ectasia.Conclusions The clinical and mammographic characteristics of plasma cell mastitis are critical to avoiding unnecessary surgery.Histopathological result is needed for the diagnosis in patients highly suspected of malignancy.

Applications of network pharmacology are increasingly widespread and methods abound in the field of drug development and pharmacological research. In this study, we choose rosiglitazone compound as the object to predict the targets and to discuss the mechanism based on three kinds of prediction methods of network pharmacology. Comparison of the prediction result has identified that the three kinds of prediction methods had their own characteristics: targets and pathways predicted were not in accordance with each other. However, the calcium signaling pathway could be predicted in the three kinds of methods, which associated with diabetes and cognitive impairment caused by diabetes by bioinformatics analysis. The above conclusion indicates that the calcium signaling pathway is important in signal pathway regulation of rosiglitazone compound, which provides a clue to further explain the mechanism of the compound and also provides a reference for the selection and application of methods of network pharmacology in the actual research.
