Objective To probe into the characteristics of men who have sex with men living in small-medium sized cities and provide scientific foundation for the formulation of strategy for AIDS prevention and control.Methods A qualitative survey was carried out by convenience sampling for thirty one selected MSM.Results Interviewees had a large age gap,widely different occupations and various degrees of education;they depended mainly on internet and friends' contacts to find their sex partners;their knowledge about HIV/STDs was poor and they were indifferent to the risk of AIDs,but were faced with enormous psychological pressure.Multiple sex partners,unprotected anal intercourse were their main high risk behaviors,and they hoped to have access to free condoms,free HIV detection and hot line consultation.Conclusion To implement prevention in an effective manner,close attention should be paid to the role of key persons within the MSM group,to increasing knowledge of the target population,to protecting their mental health and to creating a friendly social environment for their existence and effective use of internet.

OBJECTIVE:To study relative bioavailability of dauricine self-microemulsifying drug delivery system (SMEDDS) in rats. METHODS:12 rats were randomly divided into dauricine SMEDDS group (20 mg/kg) and dauricine solution group (50 mg/kg),6 rats in each group. They were given relevant medicine intragastrically. Then,0.3 ml plasma was collected from orbital venous plexus before medication and 0.167,0.333,0.5,0.75,1,2,4,8,12,24,36 h after medication. The plasma concentration of da- uricine was determined by HPLC-MS/MS,and DAS 3.0 was used to calculate pharmacokinetic parameters and evaluate the relative bioavailability of dauricine with dauricine SMEDDS. RESULTS:The linear range of dauricine in plasma were 2.12-424 ng/ml (r=0.999 9);RSDs of intra-day and inter-day were all lower than 10%. Pharmacokinetic parameters of dauricine solution and dau-ricine SMEDDS were that cmax were(126.3±37.4)ng/ml and(179.6±51.5)ng/ml;t1/2 were(11.48±4.58)and(21.79±6.59)h;AUC0-t were (1 963.5±638.3)ng·h/ml and(2 535.8±739.5)ng·h/ml;AUC0-∞ were(2 256.3±703.5)ng·h/ml and(2 854.6± 768.7)ng·h/ml,respectively. The relative bioavailability of dauricine SMEDDS were 323% and 316% by calculating with AUC0-t and AUC0-∞,respectively. CONCLUSIONS:Intragastric administration of dauricine SMEDDS can improve relative bioavailability of dauricine significantly.

Objective:To investigate the association between age and cardiac tamponade after radiofrequency ablation of atrial fibrillation(RAAF).Methods:Clinical data of patients undergone de novo AF ablation procedures at Beijing Anzhen Hospital from January 2013 to December 2016 were retrospectively collected.Patients were divided into an elderly group(age ≥60 years)and a non-elderly group(age <60 years). Logistic regression analyses were used to evaluate the association between old age and the risk of cardiac tamponade complicating RAAF.Results:A total of 5 313 patients were involved in this study, including 41 patients(0.77%)with cardiac tamponade.The proportion of cardiac tamponade was higher in the elderly group than in the non-elderly group(1.1% or 32/2 950 vs.0.4% or 9/2 363, χ2=8.489, P=0.004). One patient with cardiac tamponade in the elderly group required immediate surgical repair whereas none in the non-elderly group did.No patient died in hospital.Multivariate Logistic regression analysis showed that the risk of cardiac tamponade increased in the elderly group, compared with the non-elderly group( OR=2.570, 95% CI: 1.190-5.570, P=0.017). Stratified analysis revealed that among females and patients with oral anticoagulants, left atrium dimension < 40 mm or procedure duration≥ 120 min in the elderly group carried a higher risk of cardiac tamponade than those in the non-elderly group( OR=1.011, 2.914, 3.922 and 3.244, P<0.05). Conclusions:Old age(age ≥60 years)is an independent risk factor for cardiac tamponade complicating RAAF.

Objective:To explore the effect of post-pyloric feeding by spiral nasoenteric tubes on the prognosis of critically ill patients with acute gastrointestinal injury (AGI) grade Ⅱ.Methods:A retrospective study was performed to analyze the clinical data of critically ill adult patients with AGI grade Ⅱ, who were enrolled in three randomized controlled trials conducted by Guangdong Provincial People's Hospital for post-pyloric tube placement between April 2012 and May 2019. Data including demographic characteristics, serological indicators of nutrition, the tube tip position confirmed by abdominal X-ray 24 h after tube insertion, and intensive care unit (ICU), 28-day and hospital mortality were collected. Patients were divided into the post-pyloric feeding group and gastric feeding group according to the tube tip position. Propensity score matching method was used to perform 1:1 matching, and the differences of each index between the two groups were compared after matching. Then the influencing factors of P<0.1 were included in multivariate logistic regression analysis to investigate the potential ICU mortality risk factors of critically ill patients with AGI gradeⅡ. Factors with 0.1 level of significance from the univariate analysis were considered in the multivariate analysis. Results:There were 90 patients in post-pyloric feeding group and 90 patients in the gastric feeding group. Demographics and clinical characteristics of study population were well balanced between the two groups after matching. ICU, 28-day and hospital mortality in the post-pyloric feeding group were significantly lower than those in the gastric feeding group (4.4% vs 15.6%, 14.4% vs 27.8%, 6.7% vs 17.8%, all P < 0.05). Multivariate logistic regression analysis indicated that post-pyloric feeding was an independent protective factor [odds ratio ( OR)=0.295, 95% confidence internal (95% CI): 0.091-0.959, P=0.042] and APACHEⅡ score was an independent risk factor ( OR=1.111, 95% CI: 1.025-1.203, P=0.010) for ICU mortality of critically ill patients with AGI gradeⅡ. Conclusions:Post-pyloric feeding for critically ill patients with AGI grade Ⅱ could decrease ICU mortality and is an independent protective factor against mortality.

Objective To investigate the effect of Aidi injection combined with chemotherapy on CD+4CDhi25CDlow127regulatory T (Treg) cells in peripheral blood of advanced non-small-cell lung cancer (NSCLC).Methods Sixty patients with advanced NSCLC were randomly divided into the study group (treated with Aidi injection combined with chemotherapy) and the control group (treated with chemotherapy).The levels of CD+4CDhi25CDlow127Treg cells were detected by flow cytometry (FCM), and TGF-β1 and IL-10 levels were determined by enzyme linked immunosorbent assay (ELISA) before and after chemotherapy. A group consisted of 20 healthy persons was set up meanwhile.Results There was a significantly higher percentage of CD+4CDhi25CDlow127Treg cells in patients with NSCLC (5.77±1.50) % than that(3.84±0.96) % of healthy volunteers (P=0.000).The IL-10 and TGF-β1 levels[(24.09±6.74), (197.76±43.76) ng/ml]in the serum of patients with NSCLC were also significantly higher than that[(19.39±5.73), (141.13±32.17) ng/ml]of healthy volunteers (P =0.006,P =0.002). In control group, levels of CD+4CDhi25CDlow127 Treg cells were obviously lower than that before chemotherapy (P =0.048).Levels of TGF-β1 and IL-10[(22.25±6.79), (184.85±49.11) ng/ml]were slightly decreased, which showed no significant difference contrast to pretherapy[(24.37±8.10), (197.16±44.57) ng/ml](P =0.276, P =0.314).In study group, levels of CD+4CDhi25CDlow127Treg cells and TGF-β1, IL-10[(4.36±1.19) %,(20.16±4.73), (165.42±39.57) ng/ml]were obviously lower than that before chemotherapy[(5.78±1.50) %,(23.81±5.15), (198.35±43.68) ng/ml](P=0.000, P=0.003, P =0.006).Conclusion The CD+4CDhi25CDlow127 Treg cells in the peripheral blood of advanced NSCLC patients is significantly increased. Aidi injection combined with chemotherapy can obviously reduce the level of CD+4CDhi25CDlow127 Treg cells in patients with advanced NSCLC, and the combined therapy could improve the immune function of patients.

Objective To evaluate left atrial(LA) function in patients with prophase type 2 diabetes mellitus(T2DM) combinated with or without hypertension using left atrial volume tracking method(LAVT). Methods Thirty-one simple T2DM(T2DMI group) ,21 T2DM accompany with hypertension(T2DM2 group) and forty-five healthy subjects (control group) were enrolled in this study. Ultrasound LAVT(EUB-6500, Hitachi Medical Corporation) was applied to display and analyzed the LA volume loop imaging on the standard LV apical two and four chamber views. The maximal and the minimal LA volume (LAVmax, LAVmin) and the volume before LA contraction (LAVp) were recorded from the LA volume loop. The body surface area was used to correct these volume indexs. The LA reservoir function was assessed by calculating the total of LA filling volume (LAVItotal) and the expansion index(iLAVIe). The passive and active emptying percentage of the total emptying volume(LAVIpass, LAVIact) and the emptying index(iLAVIpass,iLAVIact) were caculated as the parameters of the LA conduit and booster pump function. Results Compared with the values in the control group, the LAVhotal,LAVIact were significantly higher and the LAVlpass,iLAVlpass were lower in the T2DM group (all P<0.05) ,while the iLAVIact was higher only seen in the T2DM2 group(P<0. 05). The LAVlact, iLAVIact were higher and the LAVIpass was lower in T2DM2 group than those in the T2DM1 group (all P<0.05). Conclusions The LA conduit hypofunction in primary in the prophase T2DM,when combinated with hypertension the LA constriction function compensatorily increased, LAVT can evaluate the function of LA in patients with T2DM accurately and rapidly.

Objective To assess the characteristics of left ventricular(LV) systolic dyssynchrony in patients with chronic heart failure (CHF) using two dimensional speckle-tracking imaging(2D-STI) and validate the correlation between LV systolic dyssynchrony and its ejection fraction (EF) measured by traditional two dimensional echocardiography. Methods Forty-two patients with CHF, which were divided into group CHF1 with 35% ＜EF≤50% and group CHF2 with EF≤35%, and 35 healthy subjects as control group were enrolled in this study. Two-dimensional echocardiography Simpson's method was used to measure EF of LV. The time from the onset of QRS complexes to systole peak strain rate from the longitudinal, radial and circumferential vectors(Tsrsl, Tsrsr, Tsrsc)was recorded and measured using 2D-STI, respectively. The standard deviation and the maximal temporal difference of Tsrsl, Tsrsr, Tsrsc (Tsrsl-SD,Tsrsr-SD,Tsrsc-SD,Tsrsl-diff,Tsrsr-diff, Tsrsc-diff)of 18 segments were calculated as indicator of LV systolic dyssynchrony. Results The indices of LV systolic dyssynchrony Tsrsl-SD,Tsrsl-diff, Tsrsr-SD, Tsrsr-diff,Tsrsc-SD,Tsrsc-diff in group CHF1 and CHF2 were significantly higher than those in the control group (P<0.05). Compared with group CHF1, those indices in CHF2 were significantly longer (P<0.05). Meanwhile, Tsrsl-SD, Tsrsr-SD, Tsrsc-SD(r = - 0.904～0.912, all P<0.05) and Tsrsl-diff, Tsrsr-diff, Tsrsc-diff(r = - 0.916～0.967, all P<0.01) had singnificantly negative correlations with LVEF, and the correlation coefficients between radial and circumferential 2D-STI dyssynchrony parameters and LVEF were higher than those between the longitudinal parameters and LVEF. Conclusions 2D-STI is a useful modality to evaluate the LV systolic asynchrony of the CHF and there is a good correlation between LVEF and the LV systolic dyssynchrony indices derived from 2D-STI.
