1.Immunologic dissonance and its clinical significance in sepsis
Medical Journal of Chinese People's Liberation Army 2017;42(2):95-102
Sepsis is essentially a result from immunological dissonance provoked by severe insults such as fulminant infection,severe trauma and extensive burns.It originates from excessive inflammatory responses and develops into immune paralysis or immunosupression.It has been demonstrated that cellular immune response plays a vital role in the pathogenesis of sepsis.In the stage of excessive inflammation,several kinds of immune cells are activated by pathogen-associated molecular patterns (PAMPs) or damage-associated molecular patterns (DAMPs) and subsequently produce a vast number of pro-inflammatory cytokines,while during the stage of immune paralysis,excessive apoptosis could result in decrease of immune cells with functional compromise.Inhibitory or regulatory immune cell subsets eventually dominate the direction of immune response and the production of inhibitory cytokines is enhanced.For clinical practice,surveillance of changes and shift in overall immune function is a basis for immunotherapy,especially to immunomodulation therapy.However,there is still a lack of adequate indexes or markers for integral evaluation of host immune state in the development of sepsis.

Objective:To investigate the relationship between serum retinol binding protein (RBP), stromal cell derived factor-1 (SDF-1) and renal function in patients with diabetic nephropathy (DKD).Methods:The patients with type 2 diabetes mellitus (T2DM) admitted to Yantai Affiliated Hospital of Binzhou Medical College from October 2017 to October 2020 were prospectively selected, 438 patients were divided into simple T2DM group ( n=276)and DKD group( n=162) according to the presence or absence of DKD, according to the ratio of urinary albinin/creatinine (UACR) were divided into normal( n=25), microalbuminuria ( n=75) and macroalbuminuria group ( n=62), according to the estimated glomerular filtration rate (eGFR) were divided into G1 stage ( n=28), G2 stage ( n=27), G3A + G3B stage ( n=35), G4 stage ( n=39)and G5 stages( n=33). The relationship between RBP, SDF-1 and renal function index UACR, serum uric acid (UA), blood urea nitrogen (BUN), β 2-microglobulin (β 2-MG) and serum creatinine (Scr) was analyzed. Measurement data of normal distribution were expressed as Mean± standard deviation ( Mean± SD). Independent sample t-test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups.Chi-square test was used to compare the enumeration data between groups. Receiver operating characteristic curve (ROC) was used to analyze the discriminant value of RBP and SDF-1 for DKD. Pearson was used for correlation analysis among indicators. Multivariate linear regression analysis was used to analyze the influencing factors of RBP. Results:In the DKD group, the duration of diabetes was longer, the levels of RBP, UACR, UA, BUN, β 2-MG, Scr were high, SDF-1 and eGFR were lower, with statistically significant differences compared with the simple T2DM group( P<0.05).The areas under the curve of RBP and SDF-1 to distinguish DKD were 0.903 and 0.868, and the optimal cut-off values was 70.71 mg/L and 5.69 ng/mL. With the increase of urinary albumin and clinical stage, the levels of RBP, UACR, UA, BUN, β 2-MG, Scr increased gradually, while SDF-1 and eGFR decreased gradually, and the differences were statistically significant ( P<0.05).RBP was positively correlated with UACR, UA, BUN, β 2-MG and Scr in DKD patients ( r=0.764, 0.787, 0.693, 0.577, 0.801, P<0.000 1), and negatively correlated with EGFR ( r=-0.782, P<0.000 1). SDF-1 was negatively correlated with UACR, UA, BUN, β 2-MG and Scr ( r=-0.744, -0.794, -0.666, -0.605, -0.820, P<0.000 1), and positively correlated with EGFR ( r=0.767, P<0.000 1). The multiple linear regression equation was RBP=29.852+ 0.007UACR+ 0.101UA+ 0.497BUN+ 0.034Scr-0.083eGFR ( P<0.001). Conclusion:RBP and SDF-1 have certain discriminant value for DKD patients in T2DM population, and the degree of DKD renal function injury is positively correlated with RBP and negatively correlated with SDF-1, the increase of UACR, UA, BUN, Scr and the decrease of eGFR are risk factors for the increase of RBP.

Objective:To evaluate the effect of remote ischemic conditioning (RIC) on left ventricular (LV) myocardial perfusion, myocardial viability, LV remodeling, regional and global LV function serially following acute myocardial infarction (AMI) in Chinese mini-pigs.Methods:AMI was established in 12 Chinese mini-pigs (8 males, 4 females; age: 6-8 months) and they were randomly divided into RIC group ( n=6) and non-RIC group ( n=6). RIC was performed in pigs by blood pressure inflation on the lower limbs for 5 min period and 4 cycles immediately after surgery. A series of myocardial perfusion imaging and gated 18F-fluorodeoxyglucose (FDG) myocardial metabolism PET/CT imaging were performed longitudinally at the 1st, 14th, 28th and 56th days after AMI, and parameters including total perfusion defect (TPD), hibernating myocardium (HM), Scar, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), summed motion score (SMS), summed thickening score (STS) and changes of these parameters were obtained. Independent-samples t test and Mann-Whitney U test were used to analyze data. Results:Nine Chinese mini-pigs survived after surgery and were performed imaging. Compared to non-RIC group ( n=4), HM at the 28th ((6.0±2.4)% vs (17.0±4.6)%; t=-4.158), TPD 14th-1st ((-11.8±5.4)% vs 9.0%(4.5%, 15.0%); z=2.449), TPD 28th-1st ((-15.3±3.9)% vs (12.0±3.0)%; t=-10.071), TPD 56th-1st ((-18.0±6.5)% vs 9.0%(4.5%, 12.0%); z=2.449), HM 28th-1st ((-10.5±6.9)% vs (8.3±2.1)%; t=-4.507), HM 56th-1st (-15.0%(-17.5%, -8.5%) vs 2.0%(0%, 7.0%); z=2.449) and LVEDV 14th-1st (-0.5(-2.5, 0) ml vs (13.0±4.4) ml; z=2.470) were reduced in RIC group ( n=5; all P<0.05). Conclusion:RIC can improve myocardial perfusion, delay LV remodeling in the acute stage and salvage hibernating myocardium in the subacute stage and chronic stage.

Chinese Journal of School Health 2020;41(12):1795-1797
Objective:
Based on the MSM college students in Tianjin, this study aims to explore the demographic and behavioral characteristics of MSM with different sexual partners, and to provide evidence and information for intervention in combination with social networks.
Methods:
According to the source and access of seeking sexual partners, 546 MSM of Tianjin college students aged 18-24 in 2018 Jan. and 2019 Dec. were divided into internet-based MSM (396) and traditional MSM (150). Chi-square test and rank-sum test were used to compare the demographic information, sexual behavior characteristics, HIV prevention and testing awareness, and psychoactive substance use of the two MSMs, and Logistic regression was used to explore factors affecting college students use of the Internet for sexual partners.
Results:
Internet-based MSM has advantages in receiving HIV testing and safety consulting services, AIDS knowledge level, and peer education in the past year (P<0.05). The psychoactive substance use of the survey population reached more than 40%, and the awareness rates of pre-exposure prophylaxis and post-exposure prophylaxis were 32.98% and 55.32%, respectively. After multivariate Logistic regression analysis, MSM students who had received condom distribution, AIDS counseling and peer education (OR=2.16, 1.98, P<0.01) were more inclined to use the Internet for sexual partners.
Conclusion
Relevant departments can use the Internet to intervene in the prevention and control of MSM in colleges and universities in terms of AIDS-related knowledge, HIV testing, and mental substances.
