The Department of Thoracic Surgery of Shanghai Chest Hospital has performed esophageal function testing for over 30 years, being the only department of its kind in China with this capability. The pressure testing and 24-hour pH/impedance monitoring of the esophagus is of great help to assist in the diagnosis and treatment of benign and malignant esophageal diseases related to it. Thanks to the esophageal function test, in addition to the routine various endoscopic anti-reflux procedures, our hospital has taken the lead in China in recent years to carry out a series of clinical and research work for benign esophageal diseases, such as the development of magnetic ring, double nedoscopic combination and new anti-reflux endoscopic techniques. In recent years, we have carried out high-resolution esophageal manometry and 24-hour pH/impedance monitoring for patients with interstitial pneumonia and pulmonary fibrosis suspected to be caused by gastroesophageal acid reflux. We can better assess the correlation between gastroesophageal reflux and pulmonary fibrosis, and to provide the different clinical treatments and even surgical interventions. The Bravo capsule is used more often in the United States, and it has obvious advantages over traditional approach for acid measurement. We strongly call for the collaboration between industry and academic institutions in this field, and the development of our own related products with independent intellectual property rights.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

RNF20, an E3 ligase critical for monoubiquitination of histone H2B at lysine 120 (H2Bub), has been implicated in the regulation of various cellar processes; however, its physiological roles in adipocytes remain poorly characterized. Here, we report that the adipocyte-specific knockout of Rnf20 (ASKO) in mice led to progressive fat loss, organomegaly and hyperinsulinemia. Despite signs of hyperinsulinemia, normal insulin sensitivity and improved glucose tolerance were observed in the young and aged CD-fed ASKO mice. In addition, high-fat diet-fed ASKO mice developed severe liver steatosis. Moreover, we observed that the ASKO mice were extremely sensitive to a cold environment due to decreased expression levels of brown adipose tissue (BAT) selective genes, including uncoupling protein 1 (Ucp1), and impaired mitochondrial functions. Significantly decreased levels of peroxisome proliferator-activated receptor gamma (Pparγ) were observed in the gonadal white adipose tissues (gWAT) from the ASKO mice, suggesting that Rnf20 regulates adipogenesis, at least in part, through Pparγ. Rosiglitazone-treated ASKO mice exhibited increased fat mass compared to that of the non-treated ASKO mice. Collectively, our results illustrate the critical role of RNF20 in control of white and brown adipose tissue development and physiological function.

Traditional Chinese medicine (TCM) formulas have attracted increasing attention worldwide in the past few years for treating complex disease including rheumatoid arthritis. However, their mechanisms are complex and remain unclear. Guan-Jie-Kang (GJK), a prescription modified from "Wu Tou Decoction," was found to significantly relieve arthritis symptoms in rats with adjuvant-induced arthritis after 30-day treatment, especially in the 24 g/kg/day group. By analyzing 1749 targets related to 358 compounds in the five herbs of GJK, we identified the possible anti-arthritis pathways of GJK, including the calcium signaling and metabolic pathways. Bone damage levels were assessed by micro-computed tomography, and greater bone protective effect was observed with GJK treatment than with methotrexate. Receptor activator of nuclear factor κB ligand (RANKL)-RANK signaling, which is related to calcium signaling, was significantly regulated by GJK. Moreover, a target metabolomics assay of serum was conducted; 17 metabolic biomarkers showed significant correlations with treatment. An integrated pathway analysis revealed that pyruvate metabolism, purine metabolism, and glycolysis metabolism were significantly associated with the effects of GJK in arthritis treatment. Thus, this study establishes a new omics analytical method integrated with bioinformatics analysis for elucidating the multi-pathway mechanisms of TCM.

Objective To study the effect of exosomes ( EXs) released from high expression of miR-132-3p mesenchymal stem cells (MSCs) on hypoxia/reoxygenation (H/R) injured endothelial cell function. Methods MSCs extracted from bone marrow of C57BL/6 mice were cultured primarily. MSCmiR-132-3p was obtained from MSCs infected with lentivirus loaded with miR-132-3p vector. At the same time,MSCNC was obtained by infecting MSCs with control lentivirus loaded with scramble sequence. EXs released from MSCNCand MSCmiR-132-3pwas isolated,and MSC-EXs and MSC-EXsmiR-132-3pwere obtained respectively. The obtained EXs and H/R damaged mouse brain microvascular endothelial cells (bend3) were co-cultured. According to culture conditions,the cells were divided into normal culture group (normal cell culture),H/R group (making a H/R model),MSC-EXs group (MSC-EXs co-culture),MSC-EXsmiR-132-3p group (MSC-EXsmiR-132-3pco-culture), and MSC-EXsmiR-132-3p+ LY294002 group ( before the cells and MSC-EXsmiR-132-3pwere co-cultured,treated by adding phosphatidyl alcohol 3 kinase [ PI3K] signaling pathway blocker LY294002 [20 μmol/L]). Quantitative real-time quantitative polymerase chain reaction was used to detect the expression of miR-132-3p in MSCs,MSC-EXs,and bend3 cells. Angiogenesis kit was used to detect angiogenic ability of bend3 cells,and 3-(4,5-dimethylthiazole-2)-2,5-diphenyltetrazolium bromide (MTT) assay was used to detect the proliferative capacity of bend3 cells. Scratch test was used to detect the migration ability of bend3 cells. hochest33258 staining showed cell apoptosis. Western blot was used to detect the phosphorylation level of protein kinase B ( Akt) . Results Compared with the H/R group, the MSC-EXs treatment group significantly improved the angiogenesis,proliferation,migration abilities, and Akt phosphorylation level of bend 3 cell damage induced by H/R (The H/R group were 3 ± 1,0. 275 ± 0. 020,147 ± 8 μm,and 0. 89 ± 0. 12,respectively;the MSC-EXs treatment group were 8 ± 3,0. 358 ± 0. 030,218 ± 10 μm, and 1. 37 ± 0. 25 μm,respectively;all P<0. 01). Apoptosis was significantly reduced (47 ± 2% vs. 63 ± 2%,all P<0. 01). Compared with the MSC-EXs treatment group,the angiogenesis,proliferation,migration abilities,and Akt phosphorylation level of bend 3 cells in the MSC-EXsmiR-132-3ptreatment group were increased (14 ±3,0. 444 ± 0.050,357±10μm,and1.67±0.23,respectively,all P<0.01).Apoptosis was significantly reduced (34±1%,all P<0. 01) . Compared with the MSC-EXsmiR-132-3ptreatment group, cell proliferation, migration, angiogenesis abilities,and Akt phosphorylation level in the MSC-EXsmiR-132-3p+LY294002 group were significantly reduced (5 ± 2,0. 304 ± 0. 050,175 ± 8 μm and 0. 95 ± 0. 11,respectively,all P<0. 01). Conclusion MSC-EXs with high expression of miR-132-3p may improve many physiological functions of H/R-induced damaged cerebrovascular endothelial cells by activating PI3K/Akt signaling pathway.

Objective To explore the effect of standing at a table while training on the upper limb function and muscle surface electromyography of hemiplegics.Methods Sixty hemiplegic persons were randomly divided into an experimental group and a control group,each of 30.The affected upper limbs of the experimental group were trained while standing at a table,while the control group was trained while sitting.Before the treatment,as well as after 2 and 4 weeks of treatment,both groups' motor functioning was evaluated using the Fugl-Mayer upper limb assessment (FMA),as well as muscle surface electromyography.Results Before the treatment there was no significant difference betweenthe two groups' average FMA scores.After 2 and 4 weeks of treatment it had increased significantly in the experimental group,but in the control group the increase was not significant until the fourth week.In terms of surface myography,significant differences were observed in the biceps femoris and gastrocnemius muscles of both groups after 2 weeks.Two weeks later there was further significant improvement in both groups except for the tibialis anterior muscles of the control group.The differences between the two groups were significant after two weeks in the electromyograms of the biceps femoris,gastrocnemius muscle and anterior tibialis.After four weeks the differences between the groups in all of the electromyograms were significant.Conclusion Compared with the traditional sitting position,standing at a table while training can effectively improve the muscle activity of the rectus abdominis and the spine so as to promote the recovery of movement in hemiplegic upper limbs.
