The current production of Chinese herbal decoction pieces faces several issues including strong subjectivity,unstable quality,low production efficiency,and a lack of intelligent systems.In order to expedite the intelligent transformation and upgrading of Chinese medicine processing,this paper delves deeply into the problems and challenges encountered in establishing a digital and intel-ligent production model for Chinese herbal pieces.Addressing the slow progress in fundamental research on traditional Chinese medi-cine processing mechanisms,the absence of online digital quality characterization techniques,the low level of production equipment in-telligence,and the lack of evaluation standards for high-quality decoction pieces,this paper proposes a"New Quality Productive Forces"formation approach driven by technological innovation.Through interdisciplinary integration methods,the paper explores the mechanisms of Chinese medicine processing in depth,clarifies the correlation between the processing procedures and the"medicinal properties-quality"relationship,and employs bionic sensing and artificial intelligence to achieve a holistic quality characterization of decoction pieces.Additionally,the use of cloud-edge collaborative big data systems is proposed to enhance intelligent upgrades of the production lines.The paper also aims to establish a high-quality decoction piece evaluation system integrating"physical-chemical-bio-logical"multimodal data fusion.This approach aims to steer the Chinese medicine processing towards becoming more efficient,precise,and sustainable,thereby promoting high-quality sustainable development of the Chinese herbal decoction industry and providing both theoretical and practical support for the modernization of traditional Chinese medicine.

Objective To explore the medication rules of Professor HUANG Li for the treatment of recurrent angina pectoris after percutaneous coronary intervention(PCI)for coronary heart disease by data mining method.Methods The prescriptions for effective cases of recurrent angina pectoris after PCI for coronary heart disease treated by Professor HUANG Li in the outpatient department of China-Japan Friendship Hospital were collected.SPSS Statistics 26.0 software and SPSS Modeler 18.0 software were used for frequency statistics,analysis of the therapeutic actions,properties,flavors and meridian tropism of the prescribed herbs as well as association rule analysis,cluster analysis and factor analysis of the herbs.Results A total of 344 Chinese medicine prescriptions were obtained,involving 209 herbs,with a cumulative frequency of 5 874 times.The top 30 Chinese medicinals were named as the high-frequency Chinese medicines,and the herbs with the frequency over 100 times in descending order were Astragali Radix,Chuanxiong Rhizoma,Puerariae Lobatae Radix,Rhodiolae Crenulatae Radix et Rhizoma,Notoginseng Radix et Rhizoma,Poria,Dalbergiae Odoriferae Lignum,Atractylodis Macrocephalae Rhizoma,Curcumae Rhizoma,Sparganii Rhizoma,Dioscoreae Rhizoma,Citri Reticulatae Pericarpium,Pinelliae Rhizoma Praeparatum,Codonopsis Radix,and Glycyrrhizae Radix et Rhizoma.The high-frequency Chinese medicinals were mostly classified as blood-activating and stasis-resolving drugs and qi-replenishing drugs.The medicinal properties of the drugs were characterized by being warm,mild,or cold,the flavors were predominated by being sweet,pungent or bitter,and the medicinals usually had the meridian tropism of the spleen,lung and liver meridians.A total of 30 association rules were mined out,cluster analysis yielded 5 herbal groups,and factor analysis yielded 11 groups of common factors.Conclusion For the treatment of cardiovascular diseases,Professor HUANG Li follows the theory of qi,blood and water,and especially pays more attention to the ascending and descending of qi movement.For qi deficiency and blood stasis contribute to the basic pathogenesis of recurrent angina pectoris after PCI,the therapy of benefiting qi,activating blood and removing stasis is recommended.Moreover,the simultaneous regulation of five zang-organs and simultaneous use of the cold and warm herbs are performed,and the herbs of benefiting qi and invigorating spleen,resolving phlegm and inducing diuresis,tranquilizing mind,promoting qi and dissipating masses,and activating blood to eliminate stasis are used for adjuvant therapy.

Aim To investigate the effects of bone-forming protein BMP9 on aerobic glycolysis,migration and invasion ability in triple-negative breast cancer MDA-MB-231 cells and the underlying mechanisms.Methods The experimental group infected MDA-MB-231 cells with human BMP9 recombinant adenovirus(AdBMP9),while the control group infected cells with empty GFP adenovirus.Lactate,glucose and ATP as-say kits were used to detect glucose uptake,lactate and ATP production.The correlation between BMP9 and key glycolytic enzyme genes in pancarcinoma was ana-lyzed using GEPIA2 database.The mRNA expression levels of GLUT1,HK2,PKM2 and LDHA in MDA-MB-231 cells after overexpression of BMP9 were detec-ted by qRT-PCR.Potential targets of BMP9 inhibiting MDA-MB-231 aerobic glycolysis were analyzed in STRING database.The expression levels of HIF-1αand downstream protein were detected by Western blot.The changes of cell migration and invasion ability after different treatments were evaluated by the scratch heal-ing assay and Transwell assay.Results Compared with the control group,BMP9 down-regulated glucose uptake,lactate production,ATP level(P＜0.01),and inhibited HIF-1α and its downstream protein ex-pression in MDA-MB-231 cells.Overexpression of HIF-1α in rescue experiment reversed the inhibitory effect of BMP9 on aerobic glycolysis,migration and in-vasion of MDA-MB-231 breast cancer cells.Conclu-sion BMP9 down-regulates HIF-1α to inhibit the aer-obic glycolysis and migration and invasion ability of MDA-MB-231 breast cancer cells.

Aim To investigate the effects of autophagy regula-ted by LncRNA SNHG3 on the proliferation,migration,invasion and EMT of human breast cancer cell line MCF-7.Methods The expression of SNHG3 in breast cancer and breast cancer cell line MCF-7 was analyzed by bioinformatics and real-time fluores-cent quantitative PCR(RT-qPCR);RNAi technology was used to construct MCF-7 recombinant cell lines with knockdown SNHG3(siSNHG3)and control(siNC),and Western blot and cellular immunofluorescence were applied to detect autophagy markers;autophagosome lysosomal fusion inhibitor BafA1 or ear-ly autophagosome formation inhibitor 3-MA was employed to treat MCF-7 cells with or without SNHG3 knockdown,Western blot was used to detect the expression of LC3-Ⅱ or p62,and the effect on autophagic vesicle formation or autophagic degradation was observed;clone formation experiment,CCK8 experiment,wound healing experiment,and Transwell experiment were used to detect the effects of siSNHG3 combined or not combined with BafA1 or 3-MA on the proliferation,lateral migration,longitudi-nal migration,and invasion of MCF-7 cells.Western blot was used to detect its effect on the EMT of MCF-7 cells.Results Bioinformatics analysis and RT-qPCR confirmed that SNHG3 was highly expressed in breast cancer and breast cancer cell line MCF-7;Western blot and cellular immunofluorescence confirmed that knockdown of SNHG3 could activate autophagy in breast cancer;the clone formation,CCK-8,wound healing,and Tran-swell experiment confirmed that downregulation of SNHG3 ex-pression could inhibit tumor proliferation,migration,and inva-sion by activating autophagy;Western blot confirmed that SNHG3 promoted EMT process of breast cancer through negative regulation of autophagy.Conclusions SNHG3 is abnormally overexpressed in breast cancer and negatively regulates autoph-agy,and can enhance the proliferation,migration,invasion and EMT process of breast cancer cells through negatively regulating autophagy,suggesting that SNHG3 is a potential target for diag-nosis and treatment of breast cancer.

Hepatic fibrosis(HF)is a pathophysiological outcome of chronic liver injury and is characterized by excessive accumulation of extracellular matrix protein.A number of studies have confirmed that the signaling pathways formed by transforming growth factor-β1(TGF-β1)and its downstream Smad family play an important role in the occurrence and development of HF,and the traditional Chinese medicine(TCM)research targeting this pathway is currently a hot spot in the reversal of HF.Therefore,taking TGF-β1/Smads signaling pathway as the entry point,this paper reviewed the mechanism of action of TCM compound formula and single drug extract in intervening TGF-β1/Smad pathway and related factors upstream and downstream of the pathway to reverse HF in recent years,revealed the targeted therapeutic effect of TCM,and provided new strategies for clarifying the mechanism of TCM.

Transient forebrain ischemia-reperfusion(I/R);Brain-derived neurotrophic factor(BDNF);Histone deacetylase 3(HDAC3);Hippocampus Objective To evaluate the effect of transient forebrain ischemia-reperfusion(I/R)on the binding of brainderived neurotrophic factor(BDNF)promoters to histone deacetylase 3(HDAC3)in the hippocampus of rat and investigate its mechanism.Methods The I/R model of SD rats(I/R group)was established by Pulsinelli four-vessel clamping method,and sham operation group(Sham group)was set at the same time,which were observed for the survival of neurons in the hippocampus of rats by Nissl staining,detected for the binding of BDNF promoters(Bdnf-p1,Bdnf-p2,Bdnf-p4 and Bdnf-p6)to HDAC3 by chromatin immunoprecipitation(ChIP)and determined for the expression of brain derived neurotrophic factor antisense(BDNF-AS)by qPCR.Results Compared with Sham group,the quantity of neurons in hippocampal CA1 region of rats decreased significantly in I/R group,while those in CA3 region and DG region showed no significant changes.The binding levels of Bdnf-p1 and Bdnf-p2 to HDAC3 in hippocampal CA1 region decreased significantly in I/R Group(t = 2.575 and 2.241 respectively,each P<0.05),while there was no significant difference in the binding levels of Bdnf-p4 and Bdnf-p6 to HDAC3(t = 1.033 and 0.348 respectively,each P>0.05);The binding levels of Bdnf-p1 and Bdnf-p2 to HDAC3 in CA3 region increased significantly(t = 12.600 and 3.191,P<0.001 and<0.05,respectively),while the binding level of Bdnf-p6 to HDAC3 decreased significantly(t = 4.029,P<0.05)and no significant difference was observed in the binding level of Bdnf-p4 to HDAC3(t = 0.175,P>0.05);In DG region,the binding level of each BDNF promoter to HDAC3 showed no significantly difference(t = 0.630 ～ 1.687,each P>0.05).Meanwhile,the expression level of BDNF-AS in hippocampal CA1 region of rats decreased significantly(t = 2.560,P<0.05),but increased significantly in hippocampal CA3 and DG regions(t = 3.543 and 3.637 respectively,each P<0.01)in I/R group.Conclusion I/R showed a significant effect on the binding level of BDNF promoter to HDAC3 in rat hippocampus,which may play a role by changing the expression level of BDNF-AS.

Based our previous work, twelve purine derivatives were designed and synthesized as dual modulators of GPR119 and DPP-4by conjugating the GPR119 activating and DPP-4 inhibiting fragments with the position 6 and 9 of purine core via an approach of merged pharmacophores. Compound 11, bearing 2-fluoro-4-methylsulphonyl anilide and cyanopyrrolidine moieties, exhibited the most potent GPR119 agonistic activities (EC₅₀ = 0.33 μmol·L^-1, IA = 71.1%) and DPP-4 inhibitory (58.4% inhibition at 10 μmol·L^-1, 21.2% inhibition at 1 μmol·L^-1) activities in the in vitro antidiabetic study. Subsequently, we performed studies on structure activity relationships and molecular docking to guide the further drug design.

Platelets are reprogrammed by cancer via a process called education, which favors cancer development. The transcriptional profile of tumor-educated platelets (TEPs) is skewed and therefore practicable for cancer detection. This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n = 3; Netherlands, n = 5; Poland, n = 1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, and early-stage ovarian cancer. However, these observations warrant prospective validations in a larger population before clinical utilities.

Objective: To investigate the misdiagnosis of area postrema syndrome (APS) manifesting as intractable nausea, vomiting and hiccups in neuromyelitis optic spectrum disease (NMOSD) and reduce the risk of misdiagnosis. Methods: We retrospectively analyzed data from NMOSD patients attending the Department of Neurology at the First Medical Center of PLA General Hospital between January 2019 and July 2021. SPSS25.0 was then used to analyze the manifestations, misdiagnosis, and mistreatment of APS. Results: A total of 207 patients with NMOSD were included, including 21 males and 186 females. The mean age of onset was 39±15 years (range: 5-72 years). The proportion of patients who were positive for serum aquaporin 4 antibody was 82.6% (171/207). In total, 35.7% (74/207) of the NMOSD patients experienced APS during the disease course; of these patients, 70.3% (52/74) had APS as the first symptom and 29.7% (22/74) had APS as a secondary symptom. The misdiagnosis rates for these conditions were 90.4% (47/52) and 50.0% (11/22), respectively. As the first symptom, 19.2% (10/52) of patients during APS presented only with intractable nausea, vomiting and hiccups; 80.8% (42/52) of patients experienced other neurological symptoms. The Departments of Gastroenterology and General Medicine were the departments that most frequently made the first diagnosis of APS, accounting for 54.1% and 17.6% of patients, respectively. The most common misdiagnoses related to diseases of the digestive system and the median duration of misdiagnosis was 37 days. Conclusions: APS is a common symptom of NMOSD and is associated with a high rate of misdiagnosis. Other concomitant symptoms often occur with APS. Gaining an increased awareness of this disease/syndrome, obtaining a detailed patient history, and performing physical examinations are essential if we are to reduce and avoid misdiagnosis.
