The interferon-γ testing and the comparative cervical skin test were compared with the simple cervical hypersensitivity test routinely used in our country in herds infected with Mycobacterium bovis, in which 167 infected cattle from 5 herds were tested with interferon-γ testing and the comparative cervical test (CCT) simultaneously and other 106 cattle were tested with other hypersensitivity tests used as control for comparison. In these 167 cattle tested with both tests, 89 cattle were proved to be positive both in interferon-γ testing and CCT using the bovine PPD of Netherland with a coincidence rate of 92.7% (89/96). In 106 cattle the coincidence rate of positive reactions detected by γ-interferon test and CCT was 93.41% (78/83.5), that detected by the routine skin of foreign country was 62.26%(66/106); and that between the hypersensitivity test of China and foreign country was 92.19% (59/64). It is obvious that the interferon-γ testing and CCT seem to have higher coincidence rate and the specificity of the skin tests used in our country was rather low. Consequently, the use of the comparative cervical skin test should be considered to replace the routinely used shin tests.

Objective To understand the cognitive and behavioral characteristics of AIDS between male-male in college students, and to provide evidence for the prevention and control strategies. Methods Using cluster random sampling method, the questionnaire survey including basic situation, the perception of HIV/AIDS of male male actors, sexual behavior and condom use and HIV/AIDS counseling detection, was used to investigate in male students of 8 universities at Beijing fangshan distric. Results A total of 2444 male college students were surveyed, 138 cases with male-male behavior were detected, and the detection rate was 5.65%. The detection rate (18.31%) of the junior college students was statistically higher than that of first-year college students (4.28%) and sophomores (6.52%, P<0.017). The awareness rates of four relevant knowledge about HIV/AIDS for 138 students were 25.36%, 15.22%, 9.42%and 13.77%respectively. The 44.93%male-male in college students had first sexual intercourse were younger than 18 years old. The proportion of students with first time male-male behavior and age <18 years was higher in the first-year college students (58.9%) than that of sophomores and junior college students (30.77%, 26.92%). The incidence rate of bisexuality was 43.48% in male-male behavior, and 73.91% was polysexual partners. The correct usage rate of condom was 31.16%. AIDS counseling detection rate was 27.54%. Conclusion The detection rate is higher in students with male-male behavior, and the awareness rate of AIDS-related knowledge is lower. A variety of high risk sexual behaviors are prevalent, so it is necessary to strengthen HIV/AIDS education and HIV/AIDS related knowledge for college students.

Tumor-associated macrophages(TAMs), abundantly infiltrated in the tumor microenvironment, have a significant influence on tumor metastasis, angiogenesis and immune escape. Therefore, TAMs-targeted immunotherapy has become a hot point in the field of cancer treatment. However, most of the conventional TAMs-targeted agents may cause serious adverse effects, such as short retention time, poor drug enrichment and drug-resistance. In order to overcome these shortcomings, nanobiotechnology has attracted considerable attention. More recently, a series of important progress for nanomedicine has been achieved in the area of drug delivery and diagnostic imaging, because of their special physical and chemical properties. Hence, the TAMs-targeted nanomedicine delivery system provides new ideas for tumor immunotherapy. This paper reviews the role of TAMs in tumor microenvironment, the tumor-promoting mechanism, and introduces the research progress of nanomedicine in TAMs polarization, nanodrug delivery, TAMs-targeted imaging and preventing the TAMs recruitment, so as to provide reference for the application of nanotechnology in tumor immunotherapy.

Objective:To investigate the relationship between carotid atherosclerosis(CAS)and subclinical left ventricular(LV)dysfunction in type 2 diabetes mellitus patients with preserved LV ejection fraction(LVEF).Methods:A total of 120 patients with type 2 diabetes mellitus who had LVEF≥50% were selected in the Department of Endocrinology, the First Affiliated Hospital of Air Force Medical University from June 2021 to October 2021. The global longitudinal strain(GLS)was obtained by two-dimensional speckle tracking echocardiography(STE)to assess subclinical LV systolic function. The mitral ratio of peak early to late diastolic filling velocity(E/A), and mitral velocity to early diastolic velocity of the mitral annulus(E/E′)ratio were obtained by pulsed tissue Doppler echocardiography to assess LV diastolic function. Acrroding to bilateral carotid ultrasound examination, the subjects were divided into normal carotid arteries group( n=46) and CAS group( n=74). Demographics and biochemical parameters were compared between two groups. Binary logistic regression and Pearson correlation analysis were used to evaluate the relationship between CAS and subclinical LV dysfunction. Results:The CAS group had a higher proportion of men, older age, and a longer duration of diabetes than the normal carotid arteries group(all P<0.05). There was no difference in LVEF and GLS between the two groups [normal carotid arteries group vs CAS group, LVEF: (60.72±4.73)% vs(60.07±4.28)%; GLS: (18.24±3.72)% vs(17.81±3.47)%, respectively; both P>0.05]. However, compared with normal carotid arteries group, E/A ratio was decreased and E/E′ ratio was significantly increased in CAS group(both P<0.01). Pearson correlation analysis showed that GLS was not correlated with carotid plaque thickness and carotid intima-media thickness(CIMT; both P>0.05). By contrast, E/E′ ratio was positively correlated with carotid plaque thickness and CIMT(both P<0.05). Binary logistic regression analysis showed that GLS and E/E′ ratio were not associated with CAS( both P>0.05). However, decreased E/A ratio was significantly associated with the existence of CAS( OR=0.09, 95% CI 0.01-0.67, P=0.018). Conclusions:In type 2 diabetes mellitus patients without overt heart failure and with preserved LVEF, the occurrence of CAS is not associated with subclinical LV systolic impairment assessed by GLS, but is significantly associated with LV diastolic dysfunction, and is independent of traditional cardiovascular risk factors.

Our previous studies found that mitochondrial uncouplers induced vasodilation. Triclosan, the broad spectrum antibacterial agent, is the active ingredient in soaps and toothpastes. It was reported that triclosan induced mitochondrial uncoupling, so we aim to investigate the effects of triclosan on vascular function of rat mesenteric arteries and aorta. The isometric tension of rat mesenteric artery and thoracic aorta was recorded by multi-wire myograph system. The cytosolic [Ca], mitochondrial reactive oxygen species (mitoROS), and mitochondrial membrane potential of smooth muscle cells (A10 cells) were measured using laser scanning confocal microscopy. Triclosan treatment relaxed phenylephrine (PE)- and high K(KPSS)-induced constriction, and pre-treatment with triclosan inhibited PE- and KPSS-induced constriction of rat mesenteric arteries. In rat thoracic aorta, triclosan also relaxed PE- and KPSS-induced constriction. Triclosan induces vasorelaxation without involving Kchannel activation in smooth muscle cells of arteries. Triclosan treatment increased cytosolic [Ca], mitochondrial ROS production and depolarized mitochondrial membrane potential in A10 cells. In conclusion, triclosan induces mitochondrial uncoupling in vascular smooth muscle cells and relaxes the constricted rat mesenteric arteries and aorta of rats. The present results suggest that triclosan would indicate vasodilation effect if absorbed excessively.
