Diagnostic value of bronchoalveolar lavage fluid galactomannan assay for invasive pulmonary aspergillosis in adults: A meta-analysis.

What Is Known And Objective: To analyse the diagnostic accuracy of bronchoalveolar lavage fluid galactomannan (BALF-GM) assay for invasive pulmonary aspergillosis (IPA) in adults to determine the optimal diagnostic cut-off by meta-analysis.

Methods: PubMed, Embase, Web of Science, Cochrane Library, China national knowledge infrastructure (CNKI), and China Wanfang databases were searched to collect relevant studies on the diagnostic value of BALF-GM for IPA from inception to March 2022. The summary receiver operating characteristic (SROC) curve was drawn to determine the optimal diagnostic cut-off.

Structures, plasmon-enhanced luminescence, and applications of heterostructure phosphors.

Heterostructure phosphor composites have been used widely in the fields of targeted bio-probes and bio-imaging, hyperthermia treatment, photocatalysis, solar cells, and fingerprint identification. The structures, plasmon-enhanced luminescence and mechanism of metal/fluorophore heterostructure composites, such as core-shell nanocrystals, multilayers, adhesion, islands, arrays, and composite optical glass, are reviewed in detail. Their extended applications were explored widely since the surface plasmon resonance effect increased the up-conversion efficiency of fluorophores significantly.

Diagnostic value of microRNA-25 in patients with non-small cell lung cancer in Chinese population: A systematic review and meta-analysis.

Objective: Previous studies have shown that microRNA-25 (miR-25) plays a key role in the occurrence and development of non-small cell lung cancer (NSCLC). Many studies have shown that there is a significant increment of miR-25 in circulating blood of patients with NSCLC. The meta-analysis aims to explore diagnostic value of miR-25 in NSCLC in Chinese population.

Meta-analysis of diagnostic and prognostic value of miR-126 in non-small cell lung cancer.

In recent years, many studies on the relationship between the expression of microRNA-126 (miR-126) and the diagnostic and prognostic value of non-small cell lung cancer (NSCLC) have been made, but the results were still controversial. The aim is to explore the expression of miR-126 and the diagnosis and prognosis value of NSCLC, and to provide relevant evidence for clinical diagnosis and treatment. Literature related to miR-126 and NSCLC were searched in PubMed, Embase, Cochrane Library, Web of Science, CNKI, and Wanfang from the inception to February 2020.

Experimental characterization of enhanced SNCR process with carbonaceous gas additives.

Carbonaceous gases such as CO and alkanes are commonly used as additives to enhance the selective non-catalytic reduction (SNCR) performance due to their high reducibility. This study compared the effect of CO and CH on NO reduction in a tubular reactor with simulated flue gas. The enhancement of CH on SNCR process was tested at extremely low temperature, i.

Objectives: To assess HIV incidence and its associated risk factors among young men who have sex with men (YMSM) in urban areas, China.

Design: The study used a prospective cohort study design and standard diagnostic tests.

Methods: A twelve-month prospective cohort study was conducted among YMSM (18-25 years old) in 8 large cities in China.

[Syphilis incidence and its risk factors in a cohort of young men who have sex with men].

Objectives: To investigate the incidence of syphilis infection and to determine the risk factors related to syphilis infection among young men who had sex with men (YMSM), which were documented for developing effective intervention to prevent sexually transmitted diseases among YMSM.

Methods: A cohort study was conducted in 8 cities (Beijing, Shanghai, Kunming,Guiyang, Chongqing, Chengdu, Urumqi and Nanning) from May to December, 2009. A total of 1 037 syphilis-negative YMSM aged 18-25 were enrolled in the cohort and the two follow-up surveys were carried out every six months.

Risk factors for syphilis among married men who have sex with men in China.

Objective: The present study aimed to estimate the prevalence of syphilis among men who have sex with men (MSM) currently married with women in cities of China and examine the related factors for syphilis among them.

Methods: "Snowballing" sampling was used to recruit participants in 4 cities from April 2008 to August 2009. Information of participants was collected anonymously and remained confidential.

Sexual risk behaviours and their correlates among gay and non-gay identified men who have sex with men and women in Chengdu and Guangzhou, China.

To better understand the behavioural characteristics and the factors associated with high risky behaviours among men who have sex with men and women (MSMW) with different orientation, we analyzed data from a cross-sectional survey of 600 MSMW in two large cities in China. Participants completed a questionnaire and underwent serological testing. Overall, human immunodeficiency virus (HIV) prevalence was 26%.

Community-based peer intervention to reduce HIV risk among men who have sex with men in Sichuan province, China.

This study evaluated the effectiveness of a community-based peer intervention to reduce HIV risk among men who have sex with men (MSM) in Sichuan province, China. The intervention was based on the Popular Opinion Leader framework, in which respected MSM peer leaders attempted to change MSM community norms related to sexual behavior and HIV risk. The intervention was conducted in a metropolitan city, with a matched city in the same province serving as a comparison.
