ObjectiveTo clarify the anti-inflammatory and lung-protective effects of Yantiao prescription on lipopolysaccharide （LPS）-induced acute lung injury （ALI）， and to explore the impact of Yantiao prescription on the metabolic pathways of arachidonic acid （AA） in vivo. MethodsThirty male C57BL/6J mice were randomly divided into the following groups based on body weight： normal group， model group， dexamethasone group （2 mg·kg^-1）， low-dose Yantiao prescription group （18 g·kg^-1）， and high-dose Yantiao prescription group （36 g·kg^-1）， with 6 mice in each group. The ALI mouse model was established by intraperitoneal injection of LPS. The treatment groups received oral gavage once a day for 7 consecutive days， and serum and lung tissue were collected at the end of the experiment. The content of pro-inflammatory cytokines tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. Hematoxylin-eosin （HE） staining was used to assess lung tissue pathology. The wet/dry weight ratio （W/D） and myeloperoxidase （MPO） activity in lung tissue were measured. The content of AA metabolites in serum and lung tissue was measured by liquid chromatography triple quadrupole-mass spectrometry （LC-MS/MS）. ResultsCompared with the conditions in the normal group， the content of serum pro-inflammatory cytokines TNF-α， IL-1β， and IL-6 in the model group was significantly increased （P<0.01）. The alveolar structure in mice was severely damaged， with markedly thickened alveolar walls and extensive inflammatory cell infiltration. The W/D ratio and MPO activity in lung tissue were significantly increased （P<0.01）. The content of AA metabolites， including prostaglandin D₂ （PGD₂）， prostaglandin E₂ （PGE₂）， 11（S）-hydroxy-eicosatetraenoic acid ［11（S）-HETE］， and 5-hydroxy-eicosatetraenoic acid （5-HETE） in serum and lung tissue was significantly increased （P<0.05）， while the content of 11，12-epoxyeicosatrienoic acid （11，12-EET） and 14，15-epoxyeicosatrienoic acid （14，15-EET） in serum was significantly decreased （P<0.01）. Compared with the results in the model group， the content of serum pro-inflammatory cytokines TNF-α， IL-1β， and IL-6 in the dexamethasone group， low-dose Yantiao prescription group， and high-dose Yantiao prescription group was significantly reduced （P<0.05）. Mild thickening of alveolar walls， scattered inflammatory cell infiltration， and relatively intact tissue structure with improved alveolar architecture were observed. The W/D ratio and MPO activity in lung tissue were significantly reduced （P<0.01）. The content of AA metabolites PGD₂， PGE₂， 11（S）-HETE， and 5-HETE in serum from the dexamethasone group was significantly decreased （P<0.05）， while the content of 14，15-EET in serum significantly increased （P<0.01）， and the content of 5-HETE in lung tissue significantly decreased （P<0.01）. In the low-dose and high-dose Yantiao prescription groups， the content of AA metabolites PGD₂， PGE₂， 11（S）-HETE， and 5-HETE in serum and lung tissue was significantly decreased （P<0.05）， while the content of 11，12-EET in both serum and lung tissue was significantly increased （P<0.05）. ConclusionYantiao prescription has significant protective effects against LPS-induced ALI， which are related to its regulation of AA metabolic pathways in vivo.

Building on the theory of "state-target differentiation and treatment" proposed by Academician TONG Xiaolin， diabetic foot ulcers （DFUs） are considered to belong to the "collateral injury" stage， characterized by the interplay of five states，i.e. dampness， heat， stasis， deficiency， and impairment. The dynamic biological process of epithelial-mesenchymal transition （EMT） is closely associated with the healing process of DFUs. The treatment of DFUs through staged differentiation under the "state-target differentiation and treatment" theory not only provides a basis for precise clinical treatment， but also offers insights into the regulatory roles of EMT in different states and potential intervention targets. The dampness state typically exits during the inflammatory phase， local inflammation and fluid metabolism disorders inducing EMT. Treatment focuses on draining dampness and alleviating edema， promoting local microcirculation， and improving tissue hypoxia. The heat state often reflects acute local inflammatory responses. Treatment emphasizes clearing heat and resolving toxins， regulating the EMT process to reduce inflammation， control infection， and alleviate redness， swollen， heat， and pain in the affected area. The stasis state mainly occurs during the proliferation phase. Treatment centers on invigorating blood and dissolving stasis， and unblocking the channels and quickening the collaterals. EMT plays a role in remodeling the extracellular matrix， promoting tissue repair and angiogenesis. The deficiency state is common in chronic phase， where treatment prioritizes tonifying qi and nourishing blood while reinforcing healthy qi and dispelling pathogens. EMT regulation focuses on restoring local tissue metabolism and improving the micro-environment to enhance tissue repair capacity. The impairment state represents the progression of disease deterioration. Treatment should focus on supplementing qi， blood， yin， and yang， and also promoting muscle growth and strengthening bones， supplementing by resolving toxins and stasis. EMT plays a role by regulating the activity of extracellular matrix-degrading enzymes to prevent excessive tissue repair and scarring， thereby facilitating the reconstruction of normal tissue structures.

To summarise clinical experience of Professor FANG Min in treating chronic spinal disease with tuina therapy based on the principle of "focusing on sinews and fine-regulating bones". It is believed that the key mechanism of chronic spinal disease lies in the imbalance of sinews and bones， with sinews being the first， accordingly， the basic treatment principle of "focusing on sinews and fine-regulating bones" is put forward. Combining with the modern anatomical science and the theory of traditional Chinese medicine acupoints and meridians， the treatment of chronic spinal disease adopts the principles of "causing instability in the first， making adjustments in the reverse direction， then recovering and standing up" and "layering tuina， and combining points， lines and surfaces organically"， which can often achieve a more satisfactory therapeutic effect.

Objective To evaluate the image quality of abdominal dual-energy CT virtual monoenergetic imaging (VMI) in patients with early gastric cancer using titanium alloy clips and assess its effectiveness on reducing metal artifacts. Methods A retrospective study was conducted, including 31 patients with gastric cancer who underwent abdominal dual-energy CT scans with titanium clips inserted in the gastric cavity. Each scan was reconstructed into mixed images (simulated 120 kVp CT) and VMIs with energy levels ranging from 40 keV to 140 keV. Metal artifacts were quantitatively evaluated by measuring the noise values in the lesion and perigastric regions. The contrast-noise ratio (CNR) of the lesion and the corresponding liver tissue was calculated to assess the image quality. Two radiologists independently evaluated the images, considering overall quality, artifact severity, lesion conspicuity, perigastric clarity, and vascular contrast. Results Quantitative analysis revealed that metal artifacts in both the lesion and perigastric regions decreased as the energy level increased. VMIs at 80-140 keV (lesion site) and 90-140 keV (perigastric space) showed significantly fewer artifacts compared to mixed images (P＜0.05). The CNR of lesions remained stable across VMIs at 50-140 keV, while the CNR of normal liver tissue decreased significantly with increasing energy (P＜0.05). In the subjective assessment, VMIs at 80-140 keV had higher artifact scores than mixed images (P＜0.05). VMIs at 70-90 keV provided better lesion conspicuity and perigastric clarity, although vascular contrast decreased significantly with increasing energy (P＜0.05). VMIs at 70-90 keV showed better overall quality (P＜0.05), though not significantly different from mixed images. Conclusions VMIs at 80 keV and 90 keV improve the visibility of lesions and perigastric regions affected by metallic clips, which combined with mixed images can enhance radiologists’ diagnostic accuracy.

ObjectiveTo observe clinical effectiveness and safety of lumbar oscillatory manipulation in the treatment of patients with lumbar disc herniation. MethodsThis study recruited 90 lumbar disc herniation patients who were randomly divided into 45 cases each in the treatment group and the control group. The treatment group was given lumbar oscillatory manipulation， while the control group was given traditional lumbar obliquely pulling manipulation， and both groups were treated twice a week for 4 weeks. The Oswestry dysfunction index （ODI） score， lumbar spine mobility， and the absolute values of difference in hardness between the left and right sides of the lumbar erector spinae muscle were compared between groups of patients before treatment and after 2 and 4 weeks of treatment； the shear wave elastic modulus of multifidus muscle and abdominal muscle thickness were compared between groups before treatment and after 4 weeks of treatment； the clinical effectiveness of the treatment was compared， and the safety evaluation was carried out. ResultsCompared with the group before treatment， the ODI scores and the the absolute values of difference in hardness between the left and right sides of the lumbar erector spinae muscle decreased after 2 and 4 weeks treatment in both groups， and the mobility of the lumbar vertebrae in all directions of anterior flexion， posterior extension， left lateral flexion， and right lateral flexion increased； the shear wave elastic modulus of bilateral multifidus muscles of the fourth lumbar vertebral segments decreased， and the thickness of abdominal muscle increased after 4 weeks of treatment in both groups （P＜0.05）. Compared with the control group， the ODI score of the treatment group decreased after 2 weeks of treatment， and the shear wave elastic modulus value of bilateral multifidus muscle of the fourth lumbar vertebral segment decreased and the thickness of abdominal muscle increased after 4 weeks of treatment （P＜0.05）. The total effective rate was 90.48% （38/42） in the treatment group and 71.43% （30/42） in the control group， and the clinical effectiveness of the treatment group was better than that of the control group （P＜0.05）. No adverse events occurred in both groups during the study. ConclusionLumbar oscillatory manipulation is superior to traditional lumbar obliquely pulling manipulation in relieving symptoms of lumbar disc herniation and improving lumbar spine function， which may be related to its improvement in the elasticity of the multifidus muscle.

Background::Hepatic ischemia-reperfusion injury (HIRI) remains a common complication during liver transplantation (LT) in patients. As a key downstream effector of the Hippo pathway, Yes-associated protein (YAP) has been reported to be involved in various physiological and pathological processes. However, it remains elusive whether and how YAP may control autophagy activation during ischemia-reperfusion.Methods::Human liver tissues from patients who had undergone LT were obtained to evaluate the correlation between YAP and autophagy activation. Both an in vitro hepatocyte cell line and in vivo liver-specific YAP knockdown mice were used to establish the hepatic ischemia-reperfusion models to determine the role of YAP in the activation of autophagy and the mechanism of regulation. Results::Autophagy was activated in the post-perfusion liver grafts during LT in patients, and the expression of YAP positively correlated with the autophagic level of hepatocytes. Liver-specific knockdown of YAP inhibited hepatocytes autophagy upon hypoxia-reoxygenation and HIRI ( P <0.05). YAP deficiency aggravated HIRI by promoting the apoptosis of hepatocytes both in the in vitro and in vivo models ( P <0.05). Attenuated HIRI by overexpression of YAP was diminished after the inhibition of autophagy with 3-methyladenine. In addition, inhibiting autophagy activation by YAP knockdown exacerbated mitochondrial damage through increasing reactive oxygen species ( P <0.05). Moreover, the regulation of autophagy by YAP during HIRI was mediated by AP1 (c-Jun) N-terminal kinase (JNK) signaling through binding to the transcriptional enhanced associate domain (TEAD). Conclusions::YAP protects against HIRI by inducing autophagy via JNK signaling that suppresses the apoptosis of hepatocytes. Targeting Hippo (YAP)-JNK-autophagy axis may provide a novel strategy for the prevention and treatment of HIRI.

Hepatic steatosis can be observed in chronic liver diseases of different etiologies. The main predisposing factors for hepatic steatosis include chronic viral hepatitis， cholestatic liver disease， alcoholic liver disease， and nonalcoholic fatty liver disease. Simple fatty liver disease is the initial manifestation of hepatic steatosis， followed by steatohepatitis， liver fibrosis， liver cirrhosis， and even hepatocellular carcinoma. With the development of medical imaging technology， magnetic resonance imaging-proton density fat fraction （MRI-PDFF） has been widely used in the diagnosis of fatty liver disease （FLD） in clinical practice. MRI-PDFF is gradually becoming the gold standard for the noninvasive diagnosis of FLD due to its high accuracy and good repeatability. This article reviews the clinical application of MRI-PDFF in liver fat quantification and related research advances.

ObjectiveTo investigate the effect of transplantation of bone marrow mesenchymal stem cells （BMSCs） co-cultured with bone marrow-derived M2 macrophages （M2-BMDMs）， named as BMSC^M2， on a rat model of liver cirrhosis induced by carbon tetrachloride （CCl₄）/2-acetaminofluorene （2-AAF）. MethodsRat BMDMs were isolated and polarized into M2 phenotype， and rat BMSCs were isolated and co-cultured with M2-BMDMs at the third generation to obtain BMSC^M2. The rats were given subcutaneous injection of CCl₄ for 6 weeks to establish a model of liver cirrhosis， and then they were randomly divided into model group （M group）， BMSC group， and BMSC^M2 group， with 6 rats in each group. A normal group （N group） with 6 rats was also established. Since week 7， the model rats were given 2-AAF by gavage in addition to the subcutaneous injection of CCl₄. Samples were collected at the end of week 10 to observe liver function， liver histopathology， and hydroxyproline （Hyp） content in liver tissue， as well as changes in the markers for hepatic stellate cells， hepatic progenitor cells， cholangiocytes， and hepatocytes. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the N group， the M group had significant increases in the activities of serum alanine aminotransferase （ALT） and aspartate aminotransferase （AST） （P<0.01）； compared with the M group， the BMSC and BMSC^M2 groups had significant reductions in ALT and AST （P<0.01）， and the BMSC^M2 group had significantly better activities than the BMSC group （P<0.05）. Compared with the N group， the M group had significant increases in Hyp content and the mRNA and protein expression levels of alpha-smooth muscle actin （α-SMA） in the liver （P<0.01）； compared with the M group， the BMSC and BMSC^M2 groups had significant reductions in Hyp content and the expression of α-SMA （P<0.05）， and the BMSC^M2 group had a significantly lower level of α-SMA than the BMSC group （P<0.01）. Compared with the N group， the M group had significant increases in the mRNA expression levels of the hepatic progenitor cell markers EpCam and Sox9 and the cholangiocyte markers CK7 and CK19 （P<0.01） and significant reductions in the expression levels of the hepatocyte markers HNF-4α and Alb （P<0.01）； compared with the M group， the BMSC and BMSC^M2 groups had significant reductions in the mRNA expression levels of EpCam， Sox9， CK7， and CK19 （P<0.05） and significant increases in the mRNA expression levels of HNF-4α and Alb （P<0.05）， and compared with the BMSC group， the BMSC^M2 group had significant reductions in the mRNA expression levels of EpCam and CK19 （P<0.05） and significant increase in the expression level of HNF-4α （P<0.05）. ConclusionM2-BMDMs can enhance the therapeutic effect of BMSCs on CCl₄/2-AAF-induced liver cirrhosis in rats， which provides new ideas for further improving the therapeutic effect of BMSCs on liver cirrhosis.
