Objective:To qualitatively and quantitatively compare and evaluate the application of the Fast BLADE sequence and the conventional BLADE sequence in 3T magnetic resonance (MR) liver T2-weighted imaging (T2WI).Methods:A total of 72 patients who underwent liver MR examination at the Chongqing People′s Hospital from December 2023 to July 2024 were selected. All patients underwent liver magnetic resonance imaging (MRI) scanning using a 3T MR scanner, including both the Fast BLADE sequence and the conventional BLADE sequence. The total imaging time of the two sequences was recorded. Two observers used a " 5-point scale" to evaluate the overall image quality, motion artifacts, and radial artifacts of the Fast BLADE and conventional BLADE sequences respectively, and measured the image signal-to-noise ratio (SNR) at the same spatial position in the two groups of images. Statistical analysis was used to evaluate the differences in imaging time and image quality between the Fast BLADE sequence and the conventional BLADE sequence in liver T2WI imaging.Results:The imaging time of the Fast BLADE sequence in liver T2WI imaging was significantly shorter than that of the conventional BLADE sequence ( P<0.01), and the image SNR was significantly higher than that of the conventional BLADE sequence ( P<0.01). The overall image quality, motion artifact reduction, and radial artifact reduction of the Fast BLADE sequence were all superior to those of the conventional BLADE sequence (all P<0.05). The Kappa coefficients for the consistency of the two observers′ evaluations on overall image quality, motion artifacts, and radial artifacts were 0.78, 0.66, and 0.71 respectively. Conclusions:The Fast BLADE sequence can shorten the imaging time and provide images with higher SNR, and thus can replace the conventional BLADE sequence for liver T2WI imaging.

The interplay between psychological pain and physical pain is one of the key issues in the research of non-suicidal self-injury (NSSI). Psychological pain, driven by negative self-perception and difficulties in emotional regulation, activates specific brain regions, such as the anterior cingulate gyrus and insula, areas that overlap with neural networks involved in physical pain. Physical pain can, in turn, activate distinct neural pathways that temporarily alleviate psychological pain. However, repeated self-injury may lead to increased pain tolerance over time, contributing to a vicious cycle. This paper reviews the potential neural network connections and interactions between psychological and physical pain in the context of NSSI behavior. It also summarizes current clinical interventions and their effectiveness in treating NSSI, aiming to offer new insights for future research and clinical practice in preventing and treating NSSI.

Objective Pulmonary oxygen poisoning resulting from hyperbaric oxygen,frequently occurs in specialized operations,without any current effective prevention or treatment measures.To elucidate the impact and mechanism of neostigmine(NEO)in combination with anisodamine(ANI)(neoscopolamine)on pulmonary oxygen toxicity.Methods The animal model of pulmonary oxygen poisoning was established.C57BL/6 mice were exposed to 2.5 ATA 99.9%oxygen for 6 h.The control group mice were injected with normal saline ip,while the treatment group mice received injections of ANI(25 mg/kg,ip)and NEO(50 μg/kg,ip).Lung tissues were collected and stained with HE to observe any pathological injuries after exposure.Evans blue stain was utilized to identify lung permeability,wet/dry lung ratio,and protein concentration in the bronchoalveolar lavage fluid(BALF)to assess the lung injury's severity.The modifications in inflammatory factors,oxidative stress indicators,and iron content in lung tissue were assessed.Results The results showed that the 2.5 ATA 99.9%oxygen-exposed group experienced a significant worsening of lung injury,as well as increased lung permeability,lung wet/dry ratio,and protein content in alveolar lavage fluid when compared to the control group.Moreover,mRNA levels of pro-inflammatory cytokines IL-1β,IL-6,TNF-α,and IFN-γ in the lung tissue of the model group were significantly elevated,while the levels of anti-inflammatory cytokines IL-4 and TGF-β were significantly reduced.The oxidative index MDA also significantly increased,while the antioxidant index GSH significantly decreased.Additionally,the expression of GPX4,a marker of ferroptosis,increased with an increase in iron content.Neoscopolamine treatment successfully reversed those effects.Conclusion The combined use of ANI and NEO had a protective effect on pulmonary oxygen poisoning.Neoscopolamine may inhibit inflammation and oxidative stress by activating the cholinergic anti-inflammatory pathway,thereby reducing the content of free iron in lung tissue and finally inhibiting cell ferroptosis.

We reported a case of a patient dignosed as tuberculosis and severe malnutrition with coronavirus disease 2019 （critical type） treated with a combination of Chinese medicine and Western medicine. Through the retrospective analysis of the diagnosis and treatment process of this patient， on the basis of Chinese medicine's understanding of the etiology and pathogenesis of “old state” and “deficient state”， the critical coronavirus pneumonia combined with pulmonary tuberculosis and severe malnutrition was mostly due to the physical condition and the invasion of epidemic toxin， resulting in dysfunctions of the internal organs such as the lungs， spleens， kidneys and other organs. Based on the understanding of the cause and mechanism of the coronavirus disease， the treatment combined Chinese and Western medical therapies was given. The western medicine was used with the main treatments of oxygen therapy， anti-viral， intestinal nutritional support， and anti-coagulation， while the Chinese medicine was used by tonifying qi， blood， yin， and yang， warming yang and dissipating cold， and clearing heat and dampness， then tonifying qi， nourishing yin and eliminating heat， in which tonifying middle and replenishing qi ran through the whole process. The integrated treatment eventually improved the patient's symptoms and accelerated the negative conversion of nucleic acid of the coronavirus.

Objective: To investigate whether plague phages were present in the indicator animals of plague foci in Yunnan Province, and to explore their epidemiological significance. Methods: Anus swabs were collected from indicator animals (dogs or cats) of the 41 plague affected villages in 26 towns of 10 cities (counties, districts) of Yunnan plague foci from November of 2015 to March of 2018. The Yersinia pestis phages were isolated by plague vaccine strain EV76. The isolation of plague phages from different plague foci, the isolation of plague phages from different canine species (cats), the polymorphism of plaque and the host spectrum of phages were analyzed. Results: A total of 1 014 indicator animals (1 003 dogs and 11 cats) were studied, and 102 of plague phages were isolated. In the 10 cities (counties, districts), plague phages were only not isolated from Lancang County, and the plague phages were isolated from the other 9 cities (counties, districts). The separation rates from high to low were as follows: Yiliang County (21.00%, 21/100), Menghai County (19.23%, 25/130), Yuanjiang County (11.63%, 10/86), Midu County (11.50%, 13/113), Wenshan County (10.10%, 10/99), Mile Country (7.07%, 7/99), Lianghe County (6.67%, 7/105), Baoshan Longyang District (4.90%, 5/102) and Gengma County (3.81%, 4/105). Of the 102 plague phages, 75 were isolated from the native dogs (Chinese pastoral dogs, 9.32%, 75/805), 20 from the pug dogs (13.70%, 20/146), 5 from the wolf dogs (17.24%, 5/29), 1 from Samoye (1/4) and 1 from Alaska dog (1/2). The plaque of the phage was divided by five appearance of complete lysis (the plate was clear), large (2.5-4.0 mm), big (1.5-< 2.5 mm), middle (0.5-< 1.5 mm) and small (< 0.5 mm). The representative phages were all of the Myoviridae family. Most of the phages could lysis the strains of Yersinia pestis, and some phages could lysis Shigella and type 5 Yersinia pseudotuberculosis (PST5). Conclusion The plague phages are present in the plague foci of Yunnan, and the phages are polymorphic.
