ABSTRACT
Objective: To determine the association between pulse pressure and the risk of new-onset diabetes in hypertensive patients. Methods: In this prospective cohort study, hypertensive patients from the Kailuan Study, who were diagnosed in 2006-2007 check-up, were screened for enrollment. Participants who finished the biennial follow-up until December 31, 2017 were finally included in this analysis. The primary outcome was incident diabetes development. The pulse pressure variables were divided into quartiles (Q1-Q4), and the Kaplan-Meier curve was used to examine and estimate the cumulative incidence of new-onset diabetes among quartiles. Cox proportional hazards regression model was performed to explore the association between pulse pressure and the risk of new-onset diabetes in hypertensive patients. Results: During an average follow-up of 8.17 years, 6 617 new-onset diabetes were identified out of the 32 917 hypertensive patients with no history or evidence of diabetes in 2006-2007 check-up. Participants were classified into quartiles according to pulse pressure levels as follows: Q1 group(<41 mmHg (1mmHg=0.133kPa))(n=7 995); Q2 group(41-<51 mmHg) (n=8 196); Q3 group (51-<61 mmHg) (n= 8 270); Q4 group (≥61 mmHg) (n=8 456). The cumulative incidences of new-onset diabetes across the quartiles were 16.94%, 19.61%, 21.07%, and 22.33%, respectively, with the incidence density was 20.27, 23.20, 24.92, and 26.10 per 1 000 person-years, respectively. The cumulative incidence of new-onset diabetes increased in proportion with increasing pulse pressure levels (P<0.01 by the Log-rank test). After multivariate adjustment, compared with the first quartile, the hazard ratios for new-onset diabetes in the third and fourth quartiles were 1.13 (95%CI 1.04-1.22, P<0.01) and 1.14 (95%CI 1.05-1.24, P<0.01), respectively. The risk of new-onset diabetes increased 5%(HR=1.05, 95%CI 1.02-1.08, P<0.01) with the fractional pulse pressure increased per 1 SD (0.13). Findings from the three sensitivity analyses were consistent with the main results in this cohort. Conclusions: Pulse pressure at baseline is positively associated with the incidence of new-onset diabetes among hypertensive individuals, and pulse pressure is an independent risk factor for the development of diabetes in hypertensive patients.
ABSTRACT
Objective: To observe the effect of the cyclophosphamide (CTX) on systemic lupus erythematosus mice by fluorescent quantitative polymerase chain reaction. Methods: (BALB/c × C57BL/J6) F1 hybrid mice were used as recipients of donor lymphocytes which were injected intravenously. Mice were randomly divided into control group and treatment group, serum autoantibody and urinary protein were measured, renal pathological changes and the situation of fungal infection were observed. Results: The reduced urinary protein, ameliorated renal lesions were found in the CTX-treated mice. Candida albicans and Aspergillus flavus were detected respectively in respiratory tract and gastrointestinal tract. Conclusions: CTX can alleviate lupus nephritis and the fluorescent quantitative PCR is a rapid and sensitive method for the detection of fungal infection.

ABSTRACT
Objective To investigate the behavioral characteristics of men who have sex with men(MSM)with sadomasochism associated bleeding and to analyze the relationship with HIV/AIDS high risk behavior.Methods Using modified snowball sampling methods(target sampling methods)to carry out a cross-sectional study on persons with behavior of sadomasochism that associated with bleeding in MSM,using a valid questionnaire.Another control group without the related behavior was set up.SPSS 13.0 was used.Results People practicing sadomasochism associated with bleeding had higher percentage in the following indicators:number of accumulated same gender sexual partners (median=20),anal intercourse(median=10),oral intercourse(median=10),hand intercourse (median=15)with same gender sexual partners,number of same gender sexual partners in the previous six months(median=4),numbers of anal intercourse(median=3),hand intercourse(median=3),were more than in the control group.People with sadomasochism associated bleeding had higher rates in the following behaviors:condom was ever broken or slipped in the previous six months (22.6%),suffering from disease of sexual transmitted infections(28.0%),involving in group-sex intercourse(34.8%),having sex with same sex strangers at the place for MSM in the previous six months(62.2%),ever having initiative or passive behavior of oral-anal sex(64.0%),fist-sex(18.9%),finger-sex(66.7%),bleeding during sexual intercourse(58.3%),first coition object was pupil (33.8%),having strong suicide attempts(33.3%)and suicide attempt(23.6%)etc.were more than in the control group.Conclusion MSM who had the behavior of sadomasochism which associated with bleeding had the higher percentage of HIV/AIDS high risk behaviors than the persons without those behaviors.The latter group called for special concern on interventions.
