Objective To evaluate the changes of left ventricular regional function in normal subjects with aging and the influencing factors by Doppler tissue imaging. Methods One hundred and twelve normal subjects were divided into four groups according to age: I group with age≤18 years old ; II group with 18 60 years old. Using a quantitative tissue velocity analysis system and tissue tracking, the peak velocities of different ventricular segments at systole, early and late diastole (Vs, Ve,Va) , the Ve/Va ratios were obtained and the effects of age, gender, heart rate and STd were analyzed. Results (1) Peak velocities of different segments of each wall were decreased one by one from mitral annulus, the basal, middle segment to the apical portion. (2) Peak velocities of different ventricular walls were significantly different, with the antero- and posterio-inter-ventricular septum being the lowest CVe (6. 89?2. 60) ,(7. 94?2. 64)cm/s]and with the latero-,posterio-,antero, and inferior walls of the left ventricle being higherCVe (9. 85?3. 02) , (9. 80?3. 09), (8. 86?3. 16), (8. 23?2. 48) cm/s] . (3) Peak velocities of different segments were associated with age, STd, BMI, heart rate and not associated with gender. (4) The Ve/Va ratios were increased one by one from mitral annulus, basal, middle segment to apical portion, and were significantly lower in III group and IV group than in I group and II group. Conclusions Peak velocities of different segments at different walls change regularly and age is the most important influencing factor to the diastolic velocities.

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.

It is the objective of this paper to study pharmacokinetics-pharmacodynamics (PK-PD) characteristics of ginsenoside Rg1 and Rb1 on the effect of inducing nitric oxide (NO) release after intravenous administration of Shengmai injection to rats with myocardial ischemia. The model of myocardial ischemia rats was produced by subcutaneous injection of isoproterenol. The serum samples were collected at different time points after intravenous administration of Shengmai injection to rats with the dose of 10.8 mL x kg(-1). The concentrations of ginsenoside Rg1 and Rb1 in serum were determined, and then the concentration-time curves were drawn. Pharmacokinetic parameters of ginsenoside Rg1 and Rb1 were calculated after the construction of pharmacokinetic models. Meanwhile, NO2- and NO3-, the metabolites of NO, in serum were determined, and then the effect-time curve was drawn. The combined PK-PD model was established based on the theory of effect compartment by Sheiner et al. Then pharmacodynamic parameters were calculated. The results indicated that the pharmacokinetics of ginsenoside Rg1 and Rb1 conformed to a two-compartment model. Ginsenoside Rg1 and Rb1 exhibited quick and slow elimination in rats respectively. The effect of Shengmai injection on inducing NO release did not relate directly with and lagged behind the concentrations of ginsenoside Rg1 and Rb1 in serum. The effect exhibited good correlation with ginsenoside Rg1 and Rb1 levels in effect compartment. The relationship between effect and serum concentration fits Sigmoid-E(max) model. This study successfully established the combined PK-PD model of ginsenoside Rg1 and Rb1 after intravenous administration of Shengmai injection to rats. The model can efficiently predict the concentration and effect of Shengmai injection in vivo.

Appropriate selection and measurement of lead biomarkers of exposure are critically important for health care management purposes, public health decision making, and primary prevention synthesis. Lead is one of the neurotoxicants that seems to be involved in the etiology of psychologies. Biomarkers are generally classified into three groups: biomarkers of exposure, effect, and susceptibility.The main body compartments that store lead are the blood, soft tissues, and bone; the half-life of lead in these tissues is measured in weeks for blood, months for soft tissues, and years for bone. Within the brain, lead-induced damage in the prefrontal cerebral cortex, hippocampus, and cerebellum can lead to a variety of neurological disorders, such as brain damage, mental retardation, behavioral problems, nerve damage, and possibly Alzheimer's disease, Parkinsons disease, and schizophrenia. This paper presents an overview of biomarkers of lead exposure and discusses the neurotoxic effects of lead with regard to children and adults.

Objective:
To learn the knowledge, attitude and behaviors of AIDS of men who have sex wth men ( MSM ) in a gay bathhouse, so as to provide evidence for AIDS prevention and control among MSM.
Methods:
From April to June of 2017, the MSM in a gay bathhouse in Wuhan were investigated. Demographic information, awareness of AIDS related knowledge, attitude towards HIV infection, dating ways and purposes, and high-risk sexual behaviors were collected and analyzed.
Results:
Among 278 MSM responded, 235 ( 84.53% ) were aware of the basic knowledge of AIDS. The awareness rates of " transfusion with HIV blood will be infected ", " sharing syringes with HIV infected people will be infected ", "proper use of condoms can reduce the spread of AIDS ", " only having sex with one partner ( or few partners ) can reduce the spread of AIDS " were more than 90%, while the awareness rate of " high risk of HIV infection in gay bathhouses " was only 56.12%. Most respondents cared about the HIV infection situation of MSM, accounting for 74.46% ( 207 cases ) ; most denied or did not know the condition of friends infected with HIV, accounting for 82.37% ( 229 cases ) . The main purpose of coming to gay bathhouses was to find sexual partners, accounting for 87.41% ( 243 cases ) . About 52.16% had sexual behaviors with both heterosexual and homosexual partners, and 66.21% of them did not often or never use condoms when having sex with heterosexual partners.
Conclusions
The MSM in a gay bathouse have lower awareness of HIV infection situation and their partners, both heterosexual and homosexual behaviors, and lower proportion of insisting on condom use.
