ObjectiveTo analyze the annual publication volume， prolific research institutions， and research hotspots in the field of shared decision-making （SDM） by utilizing CiteSpace software based on a literature review， predicting the future research focus and development direction in this area. MethodsAn advanced search was conducted in the China National Knowledge Infrastructure （CNKI） and the Web of Science Core Collection databases， with the search timeframe limited to 2004—2024. Scientific knowledge mapping analysis was performed using CiteSpace software. ResultsFrom 2004 to 2024， the volume of publications on SDM research has shown an increasing trend both domestically and internationally. In China， SDM research was mainly focused on nursing， oncology， and other fields， whereas internationally， the emphasis was on patient participation， risk communication， and the application of decision-making support tools. In China， research institutions were primarily nursing schools and specific departments in affiliated hospitals， while internationally， SDM research was concentrated in North America. Keyword analysis showed that the research hotspots in China have gradually shifted from technical topics such as decision-making trees to the practical application of patient participation and decision-making support tools， while international research has earlier moved into the areas of SDM and artificial intelligence-supported decision-making tools. ConclusionThe research hotspots of SDM， both domestically and internationally， have gradually shifted from theoretical exploration to clinical practice and technological applications. In the future， with the deeper integration of artificial intelligence and big data technologies， SDM research in China will focus more on optimizing decision-making support systems and enhancing patient participation. Promoting the localization of SDM practices， fostering multidisciplinary collaboration， and strengthening policy support will be key directions for future research.

BACKGROUND: Pulmonary arterial hypertension (PAH) presents a significant health burden in Asia and remains a critical challenge. This study aims to delineate the PAH burden in Asia from 1990 to 2021. METHODS: Using the latest data from the Global Burden of Disease 2021, we evaluated and analyzed the distributions and patterns of PAH disease burden among various age groups, sexes, regions, and countries in Asia. Additionally, we examined the associations between PAH disease burden and key health system indicators, including the socio-demographic index (SDI) and the universal health coverage (UHC) index. RESULTS: In 2021, there were 25,989 new PAH cases, 103,382 existing cases, 13,909 PAH-associated deaths, and 385,755 DALYs attributed to PAH in Asia, which accounted for approximately 60% of global PAH cases. The age-standardized rates (ASRs) for prevalence and deaths were 2.05 (95% uncertainty interval [UI]: 1.66-2.52) per 100,000 population and 0.31 (95% UI: 0.23-0.38) per 100,000 population, respectively. From 1990 to 2021, Asia reported the lowest ASRs for PAH prevalence but the highest ASRs for deaths compared to other continents. While the ASRs for prevalence increased slightly, ASRs for mortality and DALYs decreased over time. This increasing burden of PAH was primarily driven by population growth and aging. The burden was especially pronounced among individuals aged ≥60 years and <9 years, who collectively accounted for the majority of deaths and DALYs. Moreover, higher SDI and UHC levels were linked to reduced incidence, but higher prevalence rates. CONCLUSIONS Although progress has been made in reducing PAH-related mortality and DALYs, the disease continues to impose a substantial burden in Asia, particularly among older adults and young children. Region-specific health policies should focus on improving early diagnosis, expanding access to treatment, and effectively addressing the growing PAH burden in the region.

The interaction between m⁶A-methylated RNA and chromatin modification remains largely unknown. We found that targeted inhibition of bromodomain-containing protein 4 (BRD4) by siRNA or its inhibitor (JQ1) significantly decreases mRNA m⁶A levels and suppresses the malignancy of breast cancer (BC) cells via increased expression of demethylase AlkB homolog 5 (ALKBH5). Mechanistically, inhibition of BRD4 increases the mRNA stability of ALKBH5 via enhanced binding between its 3' untranslated regions (3'UTRs) with RNA-binding protein RALY. Further, BRD4 serves as a scaffold for ubiquitin enzymes tripartite motif containing-21 (TRIM21) and ALKBH5, resulting in the ubiquitination and degradation of ALKBH5 protein. JQ1-increased ALKBH5 then demethylates mRNA of extra spindle pole bodies like 1 (ESPL1) and reduces binding between ESPL1 mRNA and m⁶A reader insulin like growth factor 2 mRNA binding protein 3 (IGF2BP3), leading to decay of ESPL1 mRNA. Animal and clinical studies confirm a critical role of BRD4/ALKBH5/ESPL1 pathway in BC progression. Further, our study sheds light on the crosstalks between histone modification and RNA methylation.

Objective:To explore the potent effects of denatonium benzoate(DB)on Mas-related G protein-coupled receptor-B2(MrgprB2)-mediated rat mast cell degranulation.Methods:RBL-2H3 cells were treated with DB overnight,before challenged with MrgprB2 ligands substance P(SP).The release of β-hex from MrgprB2-activated RBL-2H3 was detected by substrate method.Detec-tion of LTC4,IL-6,TNF-α and cPLA2 activity were performed by ELISA.The Ca2+influx and the expression of RBL-2H3 MrgprB2 re-ceptors were measured by fluorescence assay.Results:The results showed 10 μmol/L,50 μmol/L,80 μmol/L,100 μmol/L DB treat-ments promoted β-hex and LTC4 releases from activated RBL-2H3,accompanied by increased Ca2+mobilization and cPLA2 activa-tion.DB treatments did not affect IL-6 and TNF-α LTC4 releases in MrgprB2-activated RBL-2H3,as well as the levels of MrgprB2 ex-pression in mast cells.Conclusion:Taken together,DB enhanced the MrgprB2-mediated RBL-2H3 degranulation in vitro,probably by up-regulating Ca2+mobilization in activated cells.

Pancreatic cancer is a disease with a high fatality rate， with a five-year survival rate of no more than 10% and a significantly increasing annual mortality rate. The common pathogenesis factors of pancreatic cancer are family inheritance， diet， pancreatitis， obesity， etc.， among which， family inheritance of pancreatic cancer is the main reason， and about 7%-10% of patients have family inheritance. Surgery is an effective way to treat pancreatic cancer in patients and improve their survival， but most people are diagnosed with pancreatic cancer at intermediate and advanced stages and lose the opportunity for surgical treatment. Therefore， radiotherapy， interventional therapy， supportive treatment， immunotherapy， and other treatments are used clinically to relieve symptoms and prolong the survival of patients. The commonly used clinical drug is gemcitabine. Although it can inhibit tumor growth and improve the condition， it can bring side effects such as bone marrow suppression， rash， digestive tract side effects， and drug resistance. The damage of these side effects to the human body is systemic. Chinese medicine can be used alone or in combination with other treatment methods to reduce the toxic and side effects of chemotherapy， restore the physical energy of patients， and reduce its related complications. Chinese medicine contains a large number of active ingredients， including alkaloids， flavonoids， saponins， phenolic acids， and organic acids， with anti-inflammatory， anti-viral， anti-tumor， and other curative effects. Many clinical studies of traditional Chinese medicine （TCM） on cancers have verified that TCM plays a positive role in tumor prevention and treatment， especially in improving and controlling clinical symptoms， and also plays a good detoxification effect on radiotherapy and chemotherapy， with good results achieved in improving bone marrow suppression， improving immunity， improving quality of life， and prolonging survival. This paper reviewed the anti-pancreatic cancer mechanism of Chinese medicine monomers based on literature in China and abroad， aiming to provide new potential drug candidates for the treatment of pancreatic cancer.

ObjectiveTo explore the meridian tropism of components in Bupleuri Radix （Chaihu， CH） based on the model of nonalcoholic steatohepatitis （NASH） and clarify the substance basis of the meridian tropism of CH in Xiaoyaosan （XYS） by means of principal component analysis. MethodEighty SPF male C57BL/6 mice were randomly assigned into 8 groups， with 10 mice in each group. Except that the blank group was fed with the methionine choline-sufficient （MCS） diet， the other mice were fed with methionine choline-deficient （MCD） diet for 4 weeks to establish the nonalcoholic steatohepatitis （NASH） model. After the established model was confirmed by hematoxylin-eosin （HE） staining， the mice were administrated with corresponding drugs by gavage once a day for 4 weeks. Specifically， the 8 groups were XYS group （2.874 g·kg^-1）， XYS-CH group （2.445 g·kg^-1）， XYS-CH+volatile oils （Vol， 0.163 mg·kg^-1） group， XYS-CH+polysaccharides （Pol， 24.067 mg·kg^-1） group， XYS-CH+flavones （Fla， 2.241 mg·kg^-1） group， and XYS-CH+saponins （Sap， 2.746 mg·kg^-1） group. The model group and the blank group were administrated with the same volume of normal saline. After the last administration， the mice were sacrificed for the collection of blood and liver tissue. The pathological changes of liver were observed by HE staining and oil red O staining. Enzyme linked immunosorbent assay （ELISA） kits were used to determine the levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， triglyceride （TG）， total cholesterol （TC）， high-density lipoprotein （HDL）， and low-density lipoprotein （LDL） in serum as well as malondialdehyde （MDA）， superoxide dismutase （SOD）， catalase （CAT）， and glutathione peroxidase （GSH-Px） in liver. SPSS Statistics 23 was used for principal component analysis and comprehensive evaluation to determine the substance basis of the meridian tropism of CH in NASH mice. ResultCompared with the blank control group， the modeling led to hepatocyte swelling， increased fat vacuoles， and appearance of inflammatory cells. Further， the modeling elevated the levels of ALT， AST， TG， TC， and LDL and lowered the HDL level in serum， and it increased the MDA level and decreased the SOD， CAT， and GSH-Px levels in liver. Compared with the model group， the administration of XYS and XYS-CH in combination with the components of CH alleviated the oxidative damage in liver （P<0.05）. The comprehensive score of the pharmacological efficacy was in a descending order as follows： XYS > XYS-CH+Sap > XYS-CH+Fla > XYS-CH+Pol > XYS-CH+Vol > XYS-CH. Among the chemical components of CH， Sap had the best effect. ConclusionSap lowers the blood lipid level， regulates the abnormal lipid metabolism， and alleviates the oxidative damage of liver， which is the substance basis for CH to exert the meridian tropism in liver.

N ⁶-methyladenosine (m⁶A) modification is critical for mRNA splicing, nuclear export, stability and translation. Fat mass and obesity-associated protein (FTO), the first identified m⁶A demethylase, is critical for cancer progression. Herein, we developed small-molecule inhibitors of FTO by virtual screening, structural optimization, and bioassay. As a result, two FTO inhibitors namely 18077 and 18097 were identified, which can selectively inhibit demethylase activity of FTO. Specifically, 18097 bound to the active site of FTO and then inhibited cell cycle process and migration of cancer cells. In addition, 18097 reprogrammed the epi-transcriptome of breast cancer cells, particularly for genes related to P53 pathway. 18097 increased the abundance of m⁶A modification of suppressor of cytokine signaling 1 (SOCS1) mRNA, which recruited IGF2BP1 to increase mRNA stability of SOCS1 and subsequently activated the P53 signaling pathway. Further, 18097 suppressed cellular lipogenesis via downregulation of peroxisome proliferator-activated receptor gamma (PPARγ), CCAAT/enhancer-binding protein alpha (C/EBPα), and C/EBPβ. Animal studies confirmed that 18097 can significantly suppress in vivo growth and lung colonization of breast cancer cells. Collectively, we identified that FTO can work as a potential drug target and the small-molecule inhibitor 18097 can serve as a potential agent against breast cancer.

Objective:To investigate the clinical effect of self-designed modified rhomboid flap in repairing rhomboid, round, and teardrop-shaped wounds on the face.Methods:A retrospective observational study was conducted. From August 2018 to April 2020, 30 patients with facial lesions admitted into Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and the People's Hospital of Jianchuan County in Yunnan province met the inclusion criteria, including 16 males and 14 females, aged 23 to 88 years. The wound area ranged from 1.0 cm×1.0 cm to 7.0 cm×5.0 cm, with 10 cases of rhomboid wounds, 12 cases of round wounds, and 8 cases of teardrop-shaped wounds. The self-designed modified rhomboid flaps were applied to repair the wounds and after that, the patients were followed up for 1 to 18 months to record the survival of flaps, wound tension, scar formation and complications after surgery.Results:No necrosis or blackening was observed at the tip of the flaps after surgery. All the flaps survived and the wounds healed well with little tension, minimal scars, and no complications.Conclusions:The self-designed modified rhomboid flap is especially suitable for facial wounds with multiple important organs, multiple anatomical subunits, and areas with large changes in soft tissue tension, which can reduce not only the rotation of the flap, but also unnecessary excision of normal skin and soft tissue.

Objective To explore causes and clinical factors associated with bronchopulmonary dyspla-sia( BPD) in very low birth weight infant ( VLBWI) and extremely low birth weight infant( ELBWI) . Methods A retrospective analysis was performed on the clinical data of VLBWI and ELBWI,whose birth weight less than1200g and diagnosed BPD in NICU of Shengjing Hospital between Jan. 1st 2010 and Dec. 31st 2014. No-BPD infants with the same birth weight and during the same period were selected as the control group. Results One handred and twenty-eight cases met the criteria of BPD,whose mean gestational age(GA) was (28. 6 ± 1. 8)weeks. Other 121cases were no-BPD,and mean GA was (30. 8 ± 1. 8)weeks. Maternal hypertension during pregnancy,gestational age,birth weight,small for age infant were lower in BPD group than those in no-BPD group. Prenatal infection,premature rupture of membrances≥18h,cesarean delivery,male,Apgar 1min≤3,intra-partum recovery,alveolar surface active substances,mechanical ventilation and the time,oxygen time were higher in BPD group than those in no-BPD group. Logistic regression analysis indicated that low gestational age( OR=1. 014,P<0. 05),male(OR=2. 771,P<0. 05),duration of invasive mechanical ventilation(OR=1. 014,P<0. 05),duration of CPAP(OR=1. 008,P<0. 05)lead to BPD. Multiple logistic regression model showed that Apgar 1min≤3(95％CI:1. 274～14. 017,χ2 = 5. 550,P=0. 018,OR=4. 226),duration of invasive mechanical ventilation(95％CI:1. 001 ～1. 004,χ2 =10. 410,P =0. 001,OR =1. 003),PDA surgery(95％CI:1. 345 ～129. 693,χ2 =4. 904,P=0. 027,OR=13. 210) were the independent risk factors for the moderate-severe BPD. Conclusion Our study showed that low GA,male,long duration of mechanical ventilation were risk factors of the development of BPD. Apgar 1min≤3,duration of mechanical ventilation,PDA surgery were related with moderate-severe BPD.
