BACKGROUND Active tuberculosis infection represents a very common and significant threat to HIV-infected patients. But measures to accurately detect it are limited. OBJECTIVE To compare and analyze the diagnostic efficacy of T-SPOT.TB alone and in combination with TST in HIV-infected patients in China. METHOD TST (tuberculin skin test) and T-SPOT.TB(More)
Tuberculosis (TB) infections, caused by multidrug‑resistant Mycobacterium tuberculosis (MDR MTB), remain a significant public health concern worldwide. The regulatory mechanisms underlying the emergence of MDR MTB strains remain to be fully elucidated, and further investigation is required in order to develop better strategies for TB control. The present(More)
Yu-ping-feng-san (YPFS) is a Chinese medical formula that is used clinically for allergic diseases and characterized by reducing allergy relapse. Our previous studies demonstrated that YPFS efficiently inhibited T helper 2 cytokines in allergic inflammation. The underlying mechanisms of action of YPFS and its effective components remain unclear. In this(More)
In this technical note, we study three sources of conservativeness in fully sequential indifference-zone procedures and quantify, by experiments, the impact of each source, in terms of the number of observations, to identify which source is critical. Then we propose new asymptotically valid procedures that lessen conservativeness by mean update with or(More)
Lemma 1 Jennison et al. [1982] Suppose that a continuation region H(t) is (−h(t), h(t)) given by a non-negative function h(t), t ≥ 0. Consider two processes: a continuous process {W(t,∆), t ≥ 0} with ∆ > 0, and a discrete process obtained by observing W(t,∆) at a random, increasing sequence of times {ti : i = 1, 2, . . .} taking values in a given countable(More)
The molecular type of environmental Cryptococcus neoformans in Beijing was not clear. Our study aims to reveal the molecular characterization of C. neoformans complex from environment in Beijing, China. A total of 435 samples of pigeon droppings from 11 different homes in Beijing were collected from August to November in 2015. Pigeon droppings were(More)
