Colorectal cancer， a leading malignant gastrointestinal tumor globally in terms of incidence and mortality， has seen a consistent annual rise in newly diagnosed cases. While conventional therapies like radiotherapy， chemotherapy， and surgery are available， problems such as lack of early diagnosis， poor prognosis， and drug resistance remain significant burdens for patients. Given the complex and diverse pathogenesis of colorectal cancer， there is an urgent clinical need for safe， effective， reliable， and multi-targeted therapeutic strategies. The Hippo signaling pathway， closely linked to mechanisms like tumorigenesis， cancer cell invasion， migration， and drug resistance， extensively participates in the occurrence and development of colorectal cancer， so targeting the signaling pathway for cancer prevention and treatment has become a crucial research direction in recent years. Traditional Chinese medicine （TCM） offers multi-faceted， multi-pathway， and multi-target advantages and becomes an important therapy for colorectal cancer by enhancing patients' immunity， improving the life quality， and prolonging survival. Studies show that the active components of TCM， including flavonoids， terpenoids， phenols， alkaloids， quinones， lignans， and saponins， as well as TCM compounds such as modified Sijunzi decoction， Jiedu Sangen decoction， Jianpi Jiedu compound， and Quyu Jiedu decoction， exhibit significant targeting effects on the Hippo signaling pathway. These TCMs can exert an anti-colorectal cancer effect through various mechanisms， such as inducing cancer cell autophagy and apoptosis， inhibiting epithelial-mesenchymal transition， reversing drug resistance of the tumor， and blocking the cancer cell cycle. This paper reviewed and analyzed Chinese and international research on the action mechanisms of TCM in regulating the Hippo signaling pathway for the prevention and treatment of colorectal cancer with a comprehensive overview presentation， aiming to provide new references and ideas for the clinical application of TCM and the development of new pharmacological agents in the prevention and treatment of colorectal cancer.

Hepatocellular carcinoma （HCC） is one of the most common malignant tumors with high incidence and mortality rates worldwide， which brings a huge burden to the physical and mental health and socio-economic life of patients. The adenosine monophosphate-activated protein kinase （AMPK） signaling pathway serves as the regulatory center of cellular energy metabolism and is closely associated with the biological activities of HCC cells， including autophagy， apoptosis， and angiogenesis， and it has become a hot topic in current cancer research. Traditional Chinese medicine drugs are abundant in natural components such as flavonoids， alkaloids， and phenols and have the characteristics of multiple targets， pathways， components， and hierarchies. By targeting the AMPK signaling pathway， these components can be used alone or in combination with conventional antitumor therapies to exert an anti-tumor effect on HCC from various aspects. This article reviews and summarizes the extracts of traditional Chinese medicine that target the AMPK signaling pathway for the prevention and treatment of HCC， in order to provide a theoretical basis and a reference for the clinical application of traditional Chinese medicine in the treatment of HCC and the development of related drugs.

According to TCM, the main pathogenesis of gastroesophageal reflux disease (GERD) is stomach disharmony and descending, and stomach qi ascending. Phlegm dampness and blood stasis are also important pathological factors of this disease. TCM treatment for GERD mainly starts from the liver, spleen and stomach. The basic treatment is to harmonize the stomach and lower the adverse, and to soothe the liver and relieve depression, invigorate the spleen and resolve dampness, promote qi and blood circulation, and clear heat and inhibit acid. Clinical treatment of GERD is mostly in the form of TCM compounds, often combined with Western medicine, which can improve symptoms, reduce recurrence rate and reduce adverse reactions. The mechanism is to inhibit gastric acid secretion, enhance lower esophageal sphincter pressure, promote gastrointestinal motility, inhibit inflammation, regulate esophageal visceral sensitivity and regulate intestinal flora.

Objective:To investigate the status and influencing factors of application, project approval and scientific research output of innovation and entrepreneurship training program in medical undergraduates.Methods:A self-made questionnaire was used to investigate the application reasons, topic selection sources, project initiation, project type, implementation, progress, scientific research output and conclusion status of full-time medical undergraduates from Batch 2016 to 2020 in West China School of Medicine of Sichuan University. They were divided into two groups according to the situation whether they applied, whether they were approved and whether they had scientific research output. And the differences between the two groups were compared by chi-square test or t- test. Results:A total of 316 valid questionnaires were collected, of which 68.04% (215/316) applied for the innovation projects, 76.28% (164/215) obtained approval and 32.93% (54/164) had research output. The main reason that hindered students from applying for projects was the lack of guidance (70/101, 69.31%), and the main reason that prompted students to apply for projects was to increase the opportunities for postgraduate recommendation (147/215, 68.37%) and evaluation and award (151/215, 70.23%, 70.23%). 62.79% (135/215) of the project topics were inspired by tutor assignment, while independent topic selection was more conducive to project initiation (68/164, 41.46% vs. 12/51, 23.53%, P=0.021). Conclusion:The medical undergraduates have relatively high application and approval rate of innovation training program, but less scientific research output. Strengthening project application and topic selection guidance and process management can further improve the quality of innovation and entrepreneurship education for college students.

Objective To investigate biomechanical effects of different joint line height on unicompartmental knee arthroplasty (UKA) and to provide biomechanical evidence for surgical decision during UKA using finite element analysis (FEA).Methods On the basis of knee joint CT data from a healthy volunteer (male,30 years old,165 cm and 60 kg) and UKA prosthesis 3D scanned data,the 3D models of normal knee and UKA were constructed.Subject-specific finite element models with inhomogeneous material property assignment were constructed for normal knee and UKA with 3 different height of joint line (-3 mm,0 mm and +3 mm).Starting from the tibial articular surface,5 sections were extracted with 2 mm interval.30 nodes were selected in medial and lateral area,respectively on each section.The mean stress value of nodes was defined as the stress level of subchondral bone.Results Mean values of stress on polyethylene upper surface of 0,-3 and+3 mm joint line position were 14.84,26.81and 20.86 MPa,and the difference was statistical significant (t0vs-3=4.896,P0vs-3=0.000;t0vs+3=3.455,P0v+3=0.008;t-3vs+3=2.579,P-3vs+3=0.020).Mean values of stress on tibial prosthesis upper surface of 0,-3 and +3 mm joint line position were 29.69,50.49 and 39.99MPa,respectively,and the difference was statistical significant(t0vs-3=5.675,P0vs-3=0.000;t0vs+3=4.755,P0v+3=0.001;t-3vs+3=4.783,P-3vs+3=0.000).When joint line was in 0 mm height,stress level of subchondral bone was similar to that of normal knee.When joint line was in-3 mm height,significantly increased stress was found on polyethylene (increased 81％) and tibial component (increased 70％) surface compared with that of 0 mm height,while stress on trabecular bone under lateral tibial articular surface also increased by 8.7％.When joint line was in +3 mm height,increased stress on polyethylene (increased 41％) and tibial component (increased by 35％) surface were less than that of-3 mm height.Stress on trabecular bone under lateral articular surface decreased by 55.6％ compared with 0 mm height.Conclusion During UKA,ensuring a normal height of joint line is benefit to keep the stress path of the medial and lateral tibia similar with normal knee and decrease the risk of premature polyethylene wear,tibial component subsidence and periprosthetic fracture.

The basic stress pathway above the acetabular dome is important for the maintenance of implant stability in acetabular reconstruction of total hip arthroplasty (THA). The purpose of this study was to describe the basic stress pathway to provide evidence for clinical acetabular reconstruction guidance of THA. A subject-specific finite element (FE) model was developed from CT data to generate 3 normal hip models and a convergence study was conducted to determine the number of pelvic trabecular bone material properties using 5 material assignment plans. In addition, in the range of 0 to 20 mm above the acetabular dome, the models were sectioned and the stress pathway was defined as two parts, i.e., 3D, trabecular bone stress distribution and quantified cortical bone stress level. The results showed that using 100 materials to define the material property of pelvic trabecular bone could assure both the accuracy and efficiency of the FE model. Under the same body weight condition, the 3D trabecular bone stress distributions above the acetabular dome were consistent, and especially the quantified cortical bone stress levels were all above 20 MPa and showed no statistically significant difference (P>0.05). Therefore, defining the basic stress pathway above the acetabular dome under certain body weight condition contributes to design accurate preoperative plan for acetabular reconstruction, thus helping restore the normal hip biomechanics and preserve the stability of the implants.
