The prevalence and risk factors of rheumatoid arthritis-associated interstitial lung disease: a systematic review and meta-analysis.

Background: Interstitial lung disease (ILD) is the most widespread and fatal pulmonary complication of rheumatoid arthritis (RA). Existing knowledge on the prevalence and risk factors of rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is inconclusive. Therefore, we designed this review to address this gap.

[Clinical Characteristics and Survival Analysis of Carbapenem-Resistant Pseudomonas Aeruginosa Colonized or Infected Patients with Hematological Disorders].

Objective: To observe the clinical characteristics and impact on mortality of carbapenem-resistant Pseudomonas aeruginosa (CRPA) colonized or infected patients with hematological disorders in order to provide evidence for the prevention and treatment of CRPA.

Methods: The patients who were colonized or infected with CRPA in the Department of Hematology of The First Affiliated Hospital of Zhejiang Chinese Medical University from January 2020 to March 2021 were selected as the research subjects, the clinical data such as hospitalization time, primary disease treatment regimen, granulocyte count, previous infection and antibiotic regimen of these patients were analyzed, meanwhile, antibiotic regimen and efficacy during CRPA infection, 30-day and long-term survival were also analyzed.

Results: A total of 59 patients were included in this study, and divided into CRPA infection group (43 cases) and CRPA colonization group (16 cases).

Comparison of ruminal straw fiber degradation and bacterial community between buffalo and Holstein fed with high-roughage diet.

Buffalo exhibits great efficiency in utilizing low-quality roughage, which can be due to the combined effect of host physiological feature and roughage diet fed. The present study was designed to compare the ruminal fiber degradation and the bacterial community attached to straws in buffalo and Holstein when fed with the same high-roughage diet using ruminal incubation technique. Rice and wheat straws were selected as the incubation substrates and sampled at 0, 4, 12, 24, 48, 72, 120, and 216 h of incubation time to measure the kinetics of dry matter (DM) and neutral detergent fiber (NDF) disappearance.

Dietary selection of metabolically distinct microorganisms drives hydrogen metabolism in ruminants.

Ruminants are important for global food security but emit the greenhouse gas methane. Rumen microorganisms break down complex carbohydrates to produce volatile fatty acids and molecular hydrogen. This hydrogen is mainly converted into methane by archaea, but can also be used by hydrogenotrophic acetogenic and respiratory bacteria to produce useful metabolites.

Traditional Chinese medicine treatment for COVID-19: An overview of systematic reviews and meta-analyses.

Background: Coronavirus disease 2019 (COVID-19) is a rapidly spreading disease that has caused an extensive burden to the world. Consequently, a large number of clinical trials have examined the efficacy of traditional Chinese medicine (TCM) for treating and preventing COVID-19, with coinciding proliferation of reviews summarizing these studies.

Objective: This study aimed to evaluate the methodological quality and evidence quality of systematic reviews and meta-analyses on the efficacy of TCM.

Arbuscular Mycorrhizal Fungi and Endophytic Fungi Activate Leaf Antioxidant Defense System of Lane Late Navel Orange.

Arbuscular mycorrhizal (AM) fungi and endophytic fungi collectively symbiose well with plants and, thus, stimulate plant growth; however, it is not clear whether field inoculation of the fungi enhances the resistance potential of plants, particularly in citrus. In the present study, we inoculated AM fungi (, , and . ) and endophytic fungi () on an eight-year-old lane late navel orange ( (L.

Human bocavirus 2 detected in Rattus norvegicus feces in China.

Bocaviruses are typical zoonotic pathogens with a wide range of hosts. Here, we report the detection of human bocavirus (HBoV) in Rattus norvegicus captured in China and the results of sequencing and phylogenetic analysis based on the partial VP1 region and the entire viral genome. A total of 357 fecal samples from rats were collected in 2015-2017 and analyzed for HBoV using PCR.

[A blind technique used in randomized controlled trials of treatment based on changes of syndromes].

Treatment based on syndrome differentiation is an essential feature of traditional Chinese medical diagnosis. The interventions based on changes of syndrome types in randomized controlled trials are complicated, leading to the difficulty of blind method enforcement. This article described a double-blind method.

[Effects of cycloartocarpin A and artocarpin extracted from Fructus Artocarpin Heterophylli on apoptosis of SMMC-7721 and SGC-7901 cells].

Objective: To investigate the effects of cycloartocarpin A (ACR-2) and artocarpin (ACR-3), monomeric compounds isolated from Fructus Artocarpi Heterophylli, on apoptosis of SMMC-7721 and SGC-7901 cell lines.

Methods: SMMC-7721 and SGC-7901 cells were routinely cultured, and divided into experiment group and control group. The SMMC-7721 cells were treated with different concentrations of ACR-2 (3.

[Responses of spatial distribution pattern of Artemisia ordosica population to the precipitation gradient on Ordos Plateau].

Five sites along the precipitation gradient (336-249 mm x a(-1)) from east to west in Ordos Plateau were selected to study the spatial distribution pattern of Artemisia ordosica population and its responses to the precipitation gradient by the methods of variance mean ratio, aggregative index, and point pattern analysis. The reduction of precipitation affected the spatial distribution pattern of A. ordosica population significantly.

[Effects of three compounds extracted from Tripterygium wilfordii Hook on angiogenesis in chick chorioallantoic membrane].

Objective: To investigate the effects of three compounds extracted from Tripterygium wilfordii Hook (TW) on angiogenesis in the chick chorioallantoic membrane (CAM).

Methods: Fifty fresh Hongkong Mahua chicken eggs were divided into five groups: PBS-treated group, TW1-, TW2- and TW3-treated groups and Rg3-treated group. After disinfection, the eggs were incubated for six days in a constant temperature box with the temperature being controlled within 37.
