Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

Objective We aimed to explore the clinical efficacy of precise electro-acupuncture stimulation in the pterygopalatine fossa for the treatment of chronic sinusitis.Methods In total,40 patients with chronic sinusitis who visited the Xiyuan Hospital,China Academy of Chinese Medical Sciences between January 2022 and January 2023 were selected.The subjects were randomly divided into two groups:the treatment group(receiving precise electro-acupuncture in the pterygopalatine fossa)and the control group(receiving standard western medical treatment),with 20 cases in each groups.The treatments were administered twice a week for a period of 12 weeks.The effectiveness of the treatments was evaluated through computed tomography(CT)of the sinus changes and the Lund-Mackay scoring system.Results In cases of total opacity and partial opacity,there were significant differences between the two patient groups before and after treatment(P<0.05).Intra-group comparison revealed statistically significant improvements in both groups before and after treatment(P<0.05).The treatment group exhibited significant improvement in various sinus conditions(P<0.05),while in the control group,a significant improvement was only observed in the left maxillary sinus(P<0.05).Inter-group comparison also demonstrated that the treatment group's improvements were superior to those of the control group across multiple indicators(P<0.05).Conclusion The precise electro-acupuncture stimulation technique in the pterygopalatine fossa demonstrated significant therapeutic effects in the treatment of chronic sinusitis,with superior outcomes with respect to radiological changes compared to standard western medicine treatment.

Objective:To establish a neonatal rat bronchopulmonary dysplasia(BPD) model induced by hyperoxia, to detect the expression of miR-876-3p in the lung tissue, and to analyze the role of miR-876-3p in the occurrence and development of BPD, so as to provide a theoretical basis for the pathogenesis, prevention and treatment of BPD.Methods:Eighty newborn SD rats were randomly divided into hyperoxia group(FiO 2 60%) and air group(FiO 2 21%). Lung tissue samples were taken on the 1st, 7th, 14th and 21st day after birth, the pathological changes of lung tissue were observed.Quantitative real-time PCR technique was used to detect the expression level of miR-876-3p. Results:Within 21 days after birth, with the prolongation of hyperoxia exposure time, the general growth of rats in hyperoxia group were lower than those in air group[14 d: (35.46±1.62) g vs.(37.08±1.25) g; 21 d: (51.92±1.83) g vs.(58.87±2.43) g]( P<0.05). On the 14th and 21st day after birth, the radial alveolar counts in lung tissue of rats in hyperoxia group were significantly reduced compared with those in air group( P<0.05). On the 7th, 14th and 21st day after birth, the alveolar septal thickness of rats in air group were lower than those in hyperoxia group( P<0.05). The expression level of miR-876-3p in hyperoxia group decreased gradually and was significantly lower on the 7th, 14th and 21st day compared with air group at the same time points[7 d: (14.97±1.13) vs.(16.64±0.89); 14 d: (11.92±0.71) vs.(16.85±0.79); 21 d: (11.39±0.79) vs.(17.52±1.17)], and the differences were all statistically significant( P all<0.01). Conclusion:In this study, a new BPD model of neonatal rats can be induced by hyperoxia and the expression level of miR-876-3p in this model is decreased.The differential expression level of miR-876-3p may play a role in the occurrence and development of BPD.

Selective occlusion of tumor vasculature has proven to be an effective strategy for cancer therapy. Among vascular coagulation agents, the extracellular domain of coagulation-inducing protein tissue factor, truncated tissue factor (tTF), is the most widely used. Since the truncated protein exhibits no coagulation activity and is rapidly cleared in the circulation, free tTF cannot be used for cancer treatment on its own but must be combined with other moieties. We here developed a novel, tumor-specific tTF delivery system through coupling tTF with the DNA aptamer, AS1411, which selectively binds to nucleolin receptors overexpressing on the surface of tumor vascular endothelial cells and is specifically cytotoxic to target cells. Systemic administration of the tTF-AS1411 conjugates into tumor-bearing animals induced intravascular thrombosis solely in tumors, thus reducing tumor blood supply and inducing tumor necrosis without apparent side effects. This conjugate represents a uniquely attractive candidate for the clinical translation of vessel occlusion agent for cancer therapy.

Objective:To investigate whether the synonymous variation of the ATP-binding cassette transporter A3 (ABCA3) gene may increase the risk of respiratory distress syndrome (RDS) in Mongolian and Han newborns in Inner Mongolia.Methods:From January 2018 to June 2019, the children of Mongolian and Han nationality who were hospitalized in the Department of Neonatal Pediatrics, affiliated Hospital of Inner Mongolia Medical University and the control group were sequenced by ABCA3 exon gene to analyze whether there was synonymous mutation in ABCA3 gene.Results:A total of 101 children with RDS were enrolled, including 37 children with Mongolian and 64 with Han children. There were 113 patients in the control group, including 45 Mongolian children and 68 Han children. Children with Mongolian and Han nationality RDS and control group can detect multiple synonymous mutation sites, such as: F353F, P585P, A227A, V150V, L982L, A928A, S1372S, P1653P, E1618E, and A1027A, etc, among them, four synonymous variants of p.A227A, p.F353F, p.P585P and p.S1372S are common synonymous mutants. In both Mongolian and Han nationality, the frequency of ABCA3 gene synonymous mutation in RDS group was significantly higher than that in control group (Mongolian: χ2=9.402, P=0.002; Han: χ2=9.348, P=0.002 ). The mutation rates of F353F and P585P in Mongolian and Han children with RDS were higher than those in the control group, and the difference was statistically significant(Mongolian F353F: χ2=5.270, P=0.022; Han F353F: χ2=5.532, P=0.019.Mongolian P585P: χ2=4.711, P=0.030; Han P585P: χ2=4.480, P=0.034). Conclusions:The synonymous variation of ABCA3 gene may increase the risk of RDS in Mongolian and Han newborns in Inner Mongolia, and F353F and P585P may be one of the susceptible genes of RDS in Mongolian and Han newborns in Inner Mongolia.

The interaction was further validated by co-immunoprecipitation. WWP1 and EI24 stably over-expressing or deleted HepG2 cells were established by using the lentivirus transduction method. Colony forming assay and cell counting kit-8 (CCK8) assay were performed to identify the effects of WWP1 and EI24 on cell proliferation. In addition, the role of WWP1 in the tumorigenicity of liver cancer in vivo was examined by subcutaneous injection of different level of WWP1 expressed HepG2 into nude mice. Results:WWP1 can interact with EI24 and ubiquitin-degrade EI24 protein. The WWP1 and EI24 over-expressing or deleted HepG2 cell lines were successfully generated. Overexpression of WWP1 decreased while knockdown of WWP1 increased the protein level of EI24. The results of CCK-8 assay showed that the relative proliferation activities of WWP1 overexpressed (WWP1-OE) group and WWP1 knockdown (shWWP1) group on 36 hours were (347.00±8.15)% and (187.08±4.86)%, respectively, significantly different from (270.33±15.01)% of control group (both P<0.05). The relative proliferation activities of EI24 overexpressed (EI24-OE) group and EI24 knockdown (shEI24) group on 36 hours were (183.75±8.11)% and (317.33±9.60)%, respectively, significantly different from (270.33±15.01) % of control group (both P<0.05). The results of colony formation assay showed that the colony numbers of control group, WWP1-OE group and shWWP1 group were (52±7)/visual field (VF), (76±4)/VF, (19±3)/VF, respectively. Overexpression of WWP1 significantly increased while knockdown of WWP1 significantly decreased the colon formation ability of HepG2 cells (both P<0.05). The colon number of control group, EI24-OE group and shEI24 group were (38±4)/VF, (10±3)/VF, (69±7)/VF, respectively. Overexpression of EI24 significantly decreased while knockdown of EI24 significantly increased the colony formation ability of HepG2 cells (both P<0.05). The results of xenograft mice model showed that the tumor volumes of control, WWP1-OE, and shWWP1 group were (1 400.00±43.71)mm 3, (2 636.67±290.45) mm 3 and (642.17±36.00)mm 3, respectively, with significant differences ( P<0.05). The tumor weight for these three groups were (1.23±0.08)g, (2.05±0.17)g, and (0.88±0.09)g, respectively, with significant differences ( P<0.05). The tumor volumes of control, EI24-OE, and shEI24 group were (1 245.17±93.10)mm 3, (662.17±60.88)mm 3 and (1 986.67±226.75)mm 3 respectively, with significant differences ( P<0.05).

Malignant peripheral nerve sheath tumor (MPNST) is a rare invasive soft tissue sarcoma that originates from peripheral nerve branches and peripheral nerve sheaths. Early radical surgery is an effective treatment for MPNST. Since it is insensitive to radiotherapy and chemotherapy, the disease manifests a rapid progression, poor prognosis and high mortality. In recent years, the translational researches on the driving factors and therapeutic targets of MPNST have been rapidly developed, including the pathways of NF1-Ras, Raf-MEK-ERK, PI3K-AKT-mTOR, Wnt signaling, and abnormal expressions of apoptotic proteins, the general loss of polycomb repressive complex 2 (PRC2), upregulation of the HDAC family, abnormal expressions of receptor tyrosine kinases, expressions of programmed cell death ligand (PD-L1), aurora kinase and various microRNAs.This review summarizes the current translational researches on potential therapeutic targets of MPNST, and the clinical trials which provide helpful information for MPNST targeted therapy.

Objective: To study the predictive value of general movements(GMs) quality assessment technique(writhing movements)on the motor development outcome of high-risk infants, so as to provide a reference basis for clinical diagnosis and treatment.
