ABSTRACT
Objective:To investigate the clinical characteristics and prognosis of bloodstream infection caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) in preterm infants, and to provide basis for early clinical diagnosis and infection control. Methods:The clinical data of infants with CRKP bloodstream infection admitted to the Preterm Infants Ward of Children′s Hospital Affiliated to Zhengzhou University from January 2015 to December 2022 were retrospectively analyzed. The risk factors for death in preterm infants caused by CRKP bloodstream infection were explored through multivariate logistic regression analysis, and the receiver operating characteristic (ROC) curve was used to analyze the clinical value of each factor on evaluating prognosis. The area under curves (AUC) of each factor in different ROC curve were compared by Delong′s test.Results:A total of 96 preterm infants with CRKP bloodstream infection were included, including 70 in the survival group and 26 in the death group. The first onset symptoms of CRKP bloodstream infection in preterm infants were persistent tachycardia (heart rate>180 per minute) (69 cases, 71.9%), fever (61 cases, 63.5%), and apnea (59 cases, 61.5%). There were 88(91.7%) cases of infection combined with septic shock, and 91(94.8%) cases required vasoactive drug support. Multivariate logistic regression analysis showed that the maximum vasoactive-inotropic score (VIS) within 48 hours of onset (odds ratio ( OR)=1.058, 95% confidence interval (95% CI) 1.022 to 1.095, P=0.001), concurrent purulent meningitis ( OR=8.029, 95% CI 1.344 to 47.972, P=0.022), and concurrent necrotizing enterocolitis (NEC) ( OR=10.881, 95% CI 1.566 to 75.580, P=0.016) were independent risk factors for death in preterm infants with CRKP bloodstream infection. The ROC curve showed that the AUCs for evaluating the prognosis of preterm infants with NEC and purulent meningitis were 0.784 and 0.711, respectively. The AUC for evaluating the prognosis of preterm infants with a maximum VIS ≥52.5 points within 48 hours of onset was 0.840, and the AUC for combining the three factors was 0.931. Compared with NEC and purulent meningitis, the AUC for combining factors was higher, the differences were statistically significant ( P=0.002, P<0.001). Conclusions:Preterm infants with CRKP bloodstream infection who have a maximum VIS ≥52.5 points within 48 hours of onset, with NEC and purulent meningitis have a higher risk of death.
ABSTRACT
Objective:To evaluate the correlation and consistency between quantitative coronary flow fraction (QFR) and cardiac magnetic resonance imaging (CMR) in assessing myocardial ischemia in patients with coronary heart disease (CAD).Methods:A retrospective analysis was conducted on the data of coronary heart disease patients who underwent load CMR examination and coronary angiography at the Beijing Anzhen Hospital, Capital Medical University from August 2017 to March 2022. CMR examination includes cardiac cine, load/rest myocardial perfusion imaging, and delayed enhancement sequence. According to the results of CMR examination, the patient′s left ventricular myocardial segments were divided into normal segment group and abnormal segment group (further divided into ischemic segment group and infarcted segment group). On the basis of coronary angiography, an artificial intelligence based platform (AngioPlus system) was applied to calculate the preoperative coronary artery QFR value of patients undergoing percutaneous coronary intervention treatment. Kappa test was used to evaluate the consistency of QFR and CMR in diagnosing abnormal myocardium; Mann Whitney U test was used to compare the differences in QFR between groups; The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of QFR in diagnosing abnormal myocardium; Spearman correlation analysis was used to clarify the relationship between myocardial infarction area and QFR value of the supplying coronary artery in patients.Results:Among the 70 CAD patients enrolled, there were 60 males and 10 females, aged (54.1±11.1)years. At the vascular level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) is moderate (Kappa value=0.514). The sensitivity and specificity of detecting abnormal myocardial segments in CAD patients were 57% and 91%, respectively. The area under the curve (AUC) value of QFR predicting abnormal myocardium in CAD patients was 0.769, and the optimal cutoff value was QFR=0.865. At this time, the sensitivity and specificity of QFR predicting myocardial injury in CAD patients were 67.2% and 84.3%, respectively. The difference in vascular QFR between the normal segment group, ischemic segment group, and infarcted segment group was statistically significant ( P<0.001), with the infarcted segment group having significantly lower QFR values than the other two groups (all P<0.01). The range of myocardial infarction was negatively correlated with the QFR value of the supplying coronary artery ( r=-0.45, P<0.001). At the patient level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) was moderate (Kappa value=0.445), with a sensitivity of 74% and a specificity of 81% for diagnosing myocardial injury in CAD patients. Conclusions:Compared with CMR, QFR has better specificity in detecting myocardial injury in CAD patients. The QFR value of the infarcted segment group is significantly lower than that of the ischemic group and the normal group. The area of myocardial infarction is negatively correlated with the QFR value of the supplying coronary artery.
ABSTRACT
Objective:To study the influence of serum triggering receptor expressed on myeloid cells 1(TREM-1)level on prognosis in elderly patients with sepsis and acute respiratory distress syndrome(ARDS).Methods:A total of 100 elderly patients with sepsis were selected as the research objects.All the patients with sepsis were divided into sepsis ARDS group and sepsis non-ARDS group.General data and TREM-1 level were compared between the two groups.The patients with sepsis ARDS were divided into death group and survival group according to the survival status during the 28-day follow-up.TREM-1 level, acute physiology and chronic health evaluation(APACHE)Ⅱ score and SOFA score were compared between the two groups.The correlation between serum TREM-1 level and procalcitonin(PCT), APACHE Ⅱ score and SOFA score was analyzed.The survival rate of high TREM-1 level group and low TREM-1 level group was compared.Results:The age, white blood cell(WBC), PCT, APACHE Ⅱ score, SOFA score and TREM-1 level of sepsis ARDS patients were significantly higher than those of non-ARDS patients( t=2.722, 6.088, 11.55, 6.889, 4.661, 6.122, all P<0.05). The incidence of sepsis ARDS patients with chronic obstructive pulmonary disease was significantly higher than that of non-ARDS patients( χ2=7.895, P<0.05). Serum TREM-1 level, APACHE Ⅱ score and SOFA score of ARDS patients in death group were significantly higher than those in survival group( t=3.293, 6.173, 4.255, all P<0.05). Serum TREM-1 level was positively correlated with PCT, APACHE Ⅱ score and SOFA score( t=0.553, 0.602, 0.636, P<0.001). The Kaplan-Meier survival curve showed that the survival rate of high TREM-1 level group was significantly lower than that of low TREM-1 level group( χ2=3.999, P=0.036). Cox regression analysis showed that TREM-1 level was a risk factor for the prognosis of ARDS patients with sepsis( HR=1.893, 95% CI: 1.049-3.414). Conclusions:Serum TREM-1 level is significantly increased in elderly patients with sepsis ARDS, which is closely related to the prognosis and can be used as a potential prognostic biomarker.
ABSTRACT
Objective:To investigate the value of radiomics features derived from cardiac MR (CMR) cine images for predicting late gadolinium enhancement (LGE) in patients with hypertrophic cardiomyopathy (HCM).Methods:Firstly, a total of 300 HCM patients with definite diagnosis who underwent CMR examination in Beijing Anzhen Hospital from May 2017 to August 2021 were retrospectively included, and were divided into a training set and a test set with a proportion of 7∶3 using random stratified sampling method. Then, a total of 89 HCM patients with definite diagnosis who underwent CMR examination in Beijing Anzhen Hospital from January 2022 to May 2023 were included for external validation. The CVI42 software was used to obtain the cardiac function parameters. Intraclass correlation coefficient (ICC), Pearson correlation coefficient and least absolute shrinkage and selection operator (LASSO) were used to select radiomics features. Finally, LASSO regression and three machine learning algorithms (including support vector machine, linear discriminant analysis and naive Bayes) were used to build prediction models. The area under the receiver operating characteristic curve (AUC) was used to evaluate the prediction value of the model.Results:Totally 1 409 features were extracted from each patient, and 19 features were retained to build radiomics signature after dimension reduction. Although no significant differences among the four methods, the prediction performance and stability of LASSO regression were relatively good. The AUC was 0.795 (95%CI 0.735-0.855) in the training set, 0.765 (95%CI 0.668-0.862) in the test set and 0.721(95%CI 0.598-0.845) in the external validation set.Conclusions:The features extracted from CMR cine images can be used to predict LGE in HCM patients. LASSO regression is recommended for model construction.
ABSTRACT
Objective:To investigate the clinical efficacy of Danggui Zicao ointment on diabetic pruritus caused by heat and wind in blood. Methods:A total of 197 patients with diabetic pruritus caused by heat and wind in blood who received treatment in Jinhua Hospital of Traditional Chinese Medicine from November 2020 to March 2022 were included in this randomized controlled study. They were randomly divided into a control group ( n = 99) and an observation group ( n = 98). Based on basic hypoglycemic treatment, the control group was given oral levocetirizine hydrochloride tablets, while the observation group was externally given Danggui Zicao ointment. Both groups were treated for 4 successive weeks. Pre- and post-treatment 12-Item Pruritus Severity Scale (12-PSS) score and clinical efficacy were compared between the two groups. Results:After 4 weeks of treatment, the 12-PSS score in each group significantly decreased compared with that before treatment ( t = 18.09, 11.31, both P < 0.05). The 12-PSS score in the observation group was (7.72 ± 1.64) points, which was significantly lower than (9.35 ± 2.18) points in the control group ( t = 3.52, P < 0.05). The total effective rate in the observation group was 87.8% (86/98), which was significantly higher than 76.8% (76/98) in the control group ( χ2 = 4.06, P < 0.05). Conclusion:Danggui Zicao ointment can effectively improve the clinical symptoms of patients with diabetic pruritus caused by heat and wind in blood, improve quality of life, and deserves clinical promotion.
ABSTRACT
Objective:To compare biomechanical stabilities between screw-plate fixation and non-cannulated screw fixation for Lisfranc ligament injury by a 3-D finite element analysis.Methods:A 3-D model of a healthy foot was developed from computed tomography images. The 1st and the 2nd dorsal tarsometatarsal ligaments and Lisfranc ligament were cut in the 3-D model of a healthy foot to establish a Lisfranc ligament injury model, in which screw-plate fixation (with 2 locking plates and 8 standard screws and one non-cannulated screw) and non-cannulated screw fixation (with 3 non-cannulated screws) for Lisfranc ligament injury were simulated respectively. Finite element analyses were carried out by Abaqus 6.14 software after loads were added in the 3-D models of screw-plate fixation and non-cannulated screw fixation for Lisfranc ligament injury. The overall stress-strain nephogram, the stress distribution and displacement of the foot bone, and the stress distribution on the internal fixation system were compared between the 2 kinds of models.Results:Under the same load, the stress of the whole screw-plate fixation was concentrated on the fixators, and the stress of the non-cannulated screws was also greater than that of the bones. In both models, the strain of the whole foot led to arch collapse, especially in the medial column. The maximum stress on the screw holes in the medial and middle columns in the screw-plate fixation model was 39.91 MPa, smaller than that in the non-cannulated screw fixation model (53.13 MPa). The relative displacement of the first metatarsal joint in the screw-plate fixation model was 8.515 × 10 -1 mm, much greater than that in the non-cannulated screw fixation model (3.893 × 10 -1 mm). Stress concentration was observed in both models. The stress of the screw-plate system was concentrated on the fibular side of the middle section of the plate used to fix the first tarsometatarsal joint, decreasing towards both ends. The maximum stress of the non-cannulated screws was located in the middle of the medial column screw for fixation of the first tarsometatarsal joint, significantly greater than those of the both ends. The maximum stress of the screw-plate system was 239.5 MPa, smaller than that of the non-cannulated screws (256.8 MPa). Conclusions:Non-cannulated screw fixation demonstrates a greater biomechanical stability for Lisfranc ligament injury than screw-plate fixation. However, the former may have a higher risk of screw breakage because it bears a greater stress.
ABSTRACT
Objective:To investigate high mobility group protein 1(HMGB1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)levels and their clinical significance in elderly patients with viral pneumonia.Methods:One hundred and sixty elderly patients with viral pneumonia admitted to the Sixth Hospital Affiliated to Anhui Medical University were enrolled as research subjects.In addition, 40 elderly people who underwent regular physical examination were considered as the control group.Patients with viral pneumonia were divided into the low-risk group, middle-risk group and high-risk group according to CURB-65 scores and pneumonia severity index(PSI)scores.HMGB1, TNF-α and IL-6 levels were compared between different groups.The correlations of CURB-65 scores and PSI scores with HMGB1, TNF-α, IL-6 levels were analyzed.Multivariate Logistic regression analysis was used to examine influencing factors for the severity of viral pneumonia in elderly patients.Results:HMGB1, TNF-α and IL-6 levels were higher in research subjects than in the control group.As the severity of viral pneumonia increased, so did HMGB1, TNF-α and IL-6 levels(all P<0.05). HMGB1, TNF-α and IL-6 levels in the severe viral pneumonia group were significantly higher than those in the non-severe viral pneumonia group( P<0.05). HMGB1, TNF-α and IL-6 levels were positively correlated with CURB-65 scores and PSI scores(CURB-65 score: r=0.463, 0.392 and 0.497, P=0.015, 0.003 and 0.025; PSI score: r=0.596, 0.515 and 0.381, P=0.007, 0.011 and 0.009). HMGB1, TNF-α and IL-6 levels were influencing factors for the severity of viral pneumonia in elderly patients( OR=1.344, 1.422 and 1.351, P=0.006, 0.015 and 0.009). Conclusions:HMGB1, TNF-α and IL-6 levels are closely correlated with the severity of viral pneumonia and are helpful for early assessment of viral pneumonia.
ABSTRACT
Objective:To evaluate the accuracy of serum concentration of procalcitonin (PCT) in differential diagnosis of the etiology of bloodstream infections (BSI).Methods:Patients hospitalized in ICU of China-Japan Friendship Hospital from January 2015 to June 2020 with BSI and with PCT test simultaneously when blood drawing for blood culture were enrolled. Sequential Organ Failure Assessment (SOFA) were calculated based on parameters on the day of blood culture. Difference of various indicators among different pathogen infections were compared. Receiver Operating Characteristic (ROC) Curve was used to analyze the value of PCT in differential diagnosis of BSI by different pathogens.Results:Among 1 456 patients with BSI,1 261 (86.6%) patients with monobacterial infection, 80 (5.5%) patients with candidiasis and 115 (7.9%) patients with mixed infection. The 28-day mortality was 24.5% (356/1 456) and the 60-day mortality was 30.6% (446/1456). Mortality of both 28-day and 60-day in the mixed group was significantly higher than that in the bacteriacemia group and candidemia group. PCT levels was significantly higher in patients with bacteremia caused by gram-negative bacteria (GNB) than that in gram-positive bacteria (GPB) infected bacteremia and candidemia {3.4 μg/L[95% confidence interval (95% CI) 0.7-17.0 μg/L] vs 1.3 μg/L (95% CI 0.4-7.3 μg/L); 3.4μg/L (95% CI was 0.7-17.0 μg/L) vs 1.1 μg/L (95% CI was 0.4-3.4 μg/L); P<0.01} . ROC curve analysis showed that: ① the optimal cut-off value of PCT in differential diagnosis of monobacterial bacteremia and candidemia was 7.25 μg/L, with specificity of 90.0% and the area under the ROC curve (AUROC) was 0.612 (95% CI 0.533-0.691). When PCT value was greater than 0.51 μg/L, the sensitivity of diagnostic of bacteremia could reach 73.3%. ② the optimal cut-off value of PCT in differential diagnosis of bacteremia caused by GNB infection and candidemia was 7.32 μg/L, with specificity of 90.0% and AUROC was 0.695 (95% CI 0.614-0.776). When PCT value was greater than 0.51 μg/L, the sensitivity of diagnostic of bacteremia caused by GNB infection was 84.9%.③ the optimal cut-off value of PCT in differential diagnosis of bacteremia caused by GNB and GPB infection was 0.52 μg/L, with sensitivity of 84.9% and AUROC was 0.713 (95% CI 0.672-0.755). When PCT value was greater than 7.36 μg/L, the specificity of diagnostic of bacteremia caused by GNB infection could reach 80.1%. Conclusions:PCT can provide additional information about the possible etiology of patients with BSI, especially as high levels often indicate the possibility of GNB bacteremia.

ABSTRACT
Objective To investigate the potential therapeutic effect of luteolin on sepsis-induced ALI and the underlying mechanisms.Methods Total of 50 mice were randomly(random number) divided into five groups:a sham control group,a sepsis-induced ALI group,and three sepsis groups pre-treated with 20,40,and 80 mg/kg body weight luteolin.Mice in the treatment groups were pre-treated with luteolin at the respective oral dose two days before ALI induction.The lungs were isolated for histopathological examinations,and the bronchoalveolar lavage fluid (BALF) was collected for biochemical analyses.Results Luteolin significantly attenuated sepsis-induced ALI.Additionally,luteolin treatment decreased protein and inflammatory cytokine concentration and the number of infiltrated inflammatory cells in BALF compared with that in the non-treated sepsis mice.Pulmonary myeloperoxidase (MPO) activity was lower in the luteolin-pre-treated sepsis groups than in the sepsis group.The mechanism underlying the protective effect of luteolin on sepsis is related to the up-regulation of certain antioxidation genes,including inducible nitric oxide synthase (iNOS),cyclooxygenase-2 (COX-2),superoxide dismutases (SODs),and heme oxygenase 1 (HO-1),and the reduction of inflammatory responses through blockage of the activation of the nuclear factor (NF)-κB pathway.Conclusions Luteolin pre-treatment inhibits sepsis-induced ALI through its anti-inflammatory and antioxidative activity,suggesting that luteolin may be a potential therapeutic agent for sepsis-induced ALI.
ABSTRACT
Objective To estimate the diagnostic value of cytology, DNA-ICM(DNA-image cytometry),cytology combined with DNA-ICM for pancreatic malignancy,and to explore the cut-off value for DNA-ICM. Methods Patients with suspicious pancreatic malignancy were retrospectively identified. In total,145 EUS-FNA specimens acquired from 140 separate patients were examined by cytology and DNA-ICM. Diagnostic values among cytology, DNA-ICM and the combination of the techniques in detecting pancreatic malignancy were compared. Results Compared with cytology, DNA-ICM had a lower sensitivity (63.0% VS 82.4%)and accuracy(69.7% VS 85.5%). After combining the techniques, the diagnostic value for pancreatic malignancy significantly improved compared with that by cytology(0.941 VS 0.912, P=0.007 0)or DNA-ICM only(0.941 VS 0.815, P<0.000 1). By using the Youden index, the cut-off value for DNA-ICM to detect pancreatic malignancy was one cell with DI(DNA index)≥2.5. Notably,with this standard, the sensitivity and accuracy of DNA-ICM significantly increased to 72.3% and 77.2%, and those of the combined techniques increased to 91.6% and 93.1%, respectively. Conclusion Automated DNA-ICM is an objective and effective method for pancreatic malignancy. Although DNA-ICM has a lower diagnostic value than that of conventional cytology, an improved value was obtained after combining the techniques.
ABSTRACT
Objective To evaluate the reporting item quality of randomized controlled trials of Chinese herbal medicine as an adjunctive therapy for advanced non-small cell lung cancer. Methods The terms including Chinese medicine, Chinese herbal medicine, randomized controlled trials, and non-small cell lung cancer were searched in Chinese and English databases by computer systems to collect relevant literatures. Based on the CONSORT 2010 (consolidated standards of reporting trials 2010), the reporting item quality of the abstracts and main text in eligible papers was evaluated. Results Ninety-five eligible studies were identified from 692 potential eligible articles. None reported all of abstract and main text items in CONSORT 2010. Only 4.12％could be identified as the randomized trial in the title. More than 40％of reports showed the scientific background or rationale in the abstract but not in the main text. Three (3.16％) eligible reports defined the primary or secondary outcome measures. None reported complete information of subjects throughout the clinical trial process. Results A total of 95 eligible papers were collected, of which 0 papers reported complete abstracts and text entries according to the CONSORT. The titles of 4.12％papers were identified as randomized trials. More than 40％of the papers only reported the study purpose or hypothesis in the abstract. 3.16％of the papers reported primary and secondary efficacy index entries, and 0 papers reported complete information of subjects from enrollment to included data analysis sets. Conclusion There is a serious problem of items shortage in the literatures of randomized controlled clinical trials on Chinese herbal medicine as an adjunctive therapy for advanced non-small cell lung cancer. The randomized controlled clinical trials of Chinese herbal medicine as an adjunctive therapy for advanced non-small cell lung cancer should be reported based on the CONSORT to improve the quality of trials.

ABSTRACT
Objective@#To analyze factors influencing antiretroviral therapy (ART) adherence among human immunodeficiency virus (HIV) patients receiving ART at the town level in Ili Kazakh Autonomous Prefecture (Ili) in May 2015 and to document enhanced ART for acquired immunodeficiency syndrome (AIDS) cases.@*Methods@#A cross-sectional survey was conducted using one-on-one interviews and data collection from the system of AIDS follow-up management in three ART services centers at the town level of Ili. The subjects were HIV-infected individuals, aged 18 years or older, who were receiving ART during the survey. The surveys collected demographic characteristics, information related to ART and status of engaging ART, smoking and drinking behavior, depression, and quality of life.@*Results@#A total of 412 participants completed the survey. The age was (41.1±8.0) years (range, 19-67 years). Approximately 60.9% (251) were male and 39.1% (161) were female. The survey showed that 75.0% (309) of participants were in good adherence and the P50 (P25, P75) of quality of life was 56.31 (50.55, 59.42). Females demonstrated better adherence to ART (82.6% (n=133)) than males (70.1% (n=76)) (χ2=8.16, P=0.005). The compliance rate of participants (78.0% (n=54)) with depression was higher than non-depressed participants (63.5% (n=255)) (χ2=7.52, P=0.008). Multivariate logistic regression analyses showed that the probability of good adherence to ART increased with increasing quality of life (OR=1.06, 95%CI:1.02-1.09). Moreover, participants who consumed alcohol or disclosed their HIV infection status to families were less likely to have good adherence to ART (OR=0.26, 95% CI:0.13-0.53 and OR=0.31, 95% CI:0.13-0.72, respectively). Additionally, employed participants were also less likely to have good adherence to ART compared with unemployed participants (OR=0.45, 95% CI:0.21-0.97).@*Conclusion@#HIV/AIDS patients primarily showed good adherence to ART. Factors related to ART adherence included alcohol consumption, informing family of infection, work status, and quality of life.
ABSTRACT
Objective To study the effect of artesunate on inflammatory responses to severe pneumonia by regulating macrophage migration inhibitory factor (MIF) in rats.Methods Total of 100 SD by random (random number) assigned,20 rats were control group,80 SD rats with severe pneumonia were caused by Klebsiella pneumoniae,60 SD rats were treated with different concentrations (20,40,80 mk/kg) of artesunate after modeling.The pathological changes of lung tissue,the level of MIF myeloperoxidase activity and inflammatory cell infiltration in lung tissue of rats were evaluated.Results After treatment with artesunate,the severity of inflammation was significantly alleviated in rats with severe pneumonia evidenced by decrease in myeloperoxidase activity [severe pneumonia:(17.5 ± 1.5) vs.treatment group:(7.5 ±2.0)] and reduction in inflammatory cell infiltration (severe pneumonia:27 × 106 vs.treatment group:12.5 × 106).Similarly,the artesunate also reduced the production of inflammatory cytokines significantly in bronchoalveolar lavage fluid (IL-1 in severe pneumonia group:(1 100 ± 50) pg/ml vs.treatment group:(400 ± 60) pg/ml;IL-6 in severe pneumonia group:(700-± 30) pg/ml vs.treatment group:(200 ±40) pg/ml;IL-10 in severe pneumonia group:(500 ± 70) pg/ml vs.treatment group:(200 ± 40) pg/ml;TNF-αin severe pneumonia group:(500 ± 80) pg/ml vs.treatment group:(150 ± 50) pg/ml.In addition,artesunate inhibited the level and production of MIF,thus inhibiting the inflammatory responses mediated by MIF.Conclusions Artesunate had a protective effect on pneumonia caused by Klebsiella pneumoniae in rats via inhibiting the inflammation responses mediated by MIF.This study provided a molecular basis for newly developed drugs applied to the treatment of pneumonia caused by Klebsiella pneumoniae in rats.
ABSTRACT
<p><b>OBJECTIVE</b>This study aimed to investigate the status of multiple sexual partners and unprotected sexual behaviors and related influencing factors among HIV-positive men who have sex with men (MSM).</p><p><b>METHODS</b>HIV-positive men having sex with men aged 18 years or older, living in Chengdu, Chongqing or Guangzhou were recruited by using the " snowballing" sampling method. Participants completed the questionnaire on computers, after filling in the Informed Consent Form. Content of the study would include social demographic characteristics, number of sexual partners, sexual behaviors, and the symptoms assessment on depression and anxiety.χ(2)-test,t-test and non-conditional Multiple logistic Regression methods were used to examine the risky sexual behaviors with multiple sexual partners among the participants engaged in this project.</p><p><b>RESULTS</b>Mean age of the 501 participants was (30.24±7.70) years old. In the past 6 months, 17.4% (87/501) of them had engaged in unprotected sexual behavior with two or more sexual partners. Factors at risk would include: being married (OR=1.93, 95%CI: 0.77-4.84), divorced or widowed (OR=3.94, 95%CI: 1.66-9.36), having primary male sexual partners (OR=5.04, 95%CI: 1.08-23.54) and casual or commercial male sexual partners (OR=2.54, 95%CI: 1.34-4.80) in the past 6 months, drinking alcohol (OR=3.00, 95%CI: 1.37-6.62) or Rush (alkyl nitrite) (OR=3.53, 95%CI: 1.72-7.23) during sexual acts, sharing their HIV-infection status to their partly primary male sexual partners (OR=1.84, 95%CI:0.78-4.33) or not (OR=2.68, 95% CI: 1.25-5.73), and having high sexual sensation seeking scores (OR=1.09, 95%CI: 1.03-1.15).</p><p><b>CONCLUSIONS</b>Unprotected sexual behaviors with multiple sexual partners among HIV-positive MSM played an important role in expediting the HIV transmission. Development of intervention programs to minimize the risk sexual behaviors and setting up efficient medical and biological measures in controlling the HIV transmission were in urgent need.</p>
