Breast cancer is one of the most common cancers in the world， and its incidence rate is also rising in China and tends to happen in younger age groups. The classical Wnt/β-catenin signaling pathway is an important target in the treatment of breast cancer， playing a key role in the whole process of breast cancer development by regulating the expression of related signal proteins and genes. Traditional Chinese medicine has a profound history and practical experience in the treatment of malignant tumors， and the development of modern technology further highlights the therapeutic advantages of traditional Chinese medicine， which has multiple targets and components. Research shows that Chinese medicine can effectively slow down the proliferation of breast cancer cells by regulating the Wnt/β-catenin signaling pathway， and has a significant inhibitory effect on the development of breast cancer. Based on this， this paper summarized domestic and foreign relevant studies on the regulation of the Wnt/β-catenin signaling pathway with traditional Chinese medicine in the treatment of breast cancer， analyzed the mechanism of traditional Chinese medicine treating breast cancer by intervening in this signaling pathway， and summarized 44 different types of traditional Chinese medicine monomers， including terpenes （triptolide， andrographolide， etc.）， flavonoids （scutellarin， sinensetin， etc.）， polysaccharides （Angelica sinensis polysaccharides， etc.）， phenols （curcumin， polydatin， etc.）， and alkaloids （lycorine， etc.）. In addition， there are 3 traditional Chinese medicines （Ganoderma lucidum， Radix actinidia chinensis， and Antrodia camphorata）， 1 group of medicine pairs （Trionycis Carapax-Zedoary Turmeric）， and 8 traditional Chinese medicine formulas （Compound Tubeimu， Huangqi Jiedu Tang， Xihuang Wan， Liuwei Dihuang Wan， Jiazhu Tang， Aiduqing Fang， Sini San， and compound Kushen injection）. By regulating the Wnt/β-catenin signaling pathway and its key molecules， these single herbs， monomers， and compound herbs can reverse the epithelial mesenchymal transformation process， reduce the activity of stem cells， and inhibit the growth and metastasis of cancer cells. Besides， it can also enhance the sensitivity of drugs and radiotherapy and combat breast cancer， providing a new perspective for drug development and treatment strategies for breast cancer.

Prostate cancer is a malignant tumor that primarily arises from the epithelial tissue of the prostate in men. With the aggravation of population aging in China， the incidence rate of this disease has been continuously rising. Although the exact cause of prostate cancer remains unclear， it has been proven to be closely related to various factors， including individual genetic susceptibility， genetic mutations， dietary habits， and lifestyle. Research has shown that abnormal activation of the Wnt/β-catenin signaling pathway also plays an important role in the occurrence and development of prostate cancer. Multiple experimental results have revealed that traditional Chinese medicine （TCM）， with its multi-target and multi-stage mechanisms of action， exerts significant regulatory effects on key biological processes such as proliferation， migration， invasion， angiogenesis， and epithelial-mesenchymal transition （EMT） of prostate cancer cells. TCM has shown excellent potential in preventing prostate cancer progression and improving patient prognosis and has become a research focus in prostate cancer treatment in recent years. Based on this， this study reviewed the research on the regulation of the Wnt/β-catenin signaling pathway by TCM in the treatment of prostate cancer at home and abroad. It analyzed the mechanisms by which TCM intervention exerts anti-prostate cancer effects via this signaling pathway， identifying 29 different types of active ingredients in TCM， including alkaloids （e.g.， capsaicin， berberine）， flavonoids （e.g.， icariin and hyperoside）， polyphenols （e.g.， gastrodin and honokiol）， terpenes （e.g.， oridonin）， quinones （e.g.， aloe-emodin）， coumarins （e.g.， agrimonolide）， and saponins （e.g.， saikosaponin-d）. Additionally， one TCM medicinal substance （arsenic）， one drug pair （Danggui - Qieyi combination）， and two TCM formulae （Yishen Tonglong Tang and Guben Qingyuan Formula） were included. The study aims to deepen the understanding of the pathological mechanism of prostate cancer and to explore possible therapeutic targets， thereby providing new perspectives and approaches for clinical research and new drug development， and ultimately promoting the advancement and innovation of prostate cancer treatment strategies.

Objective To evaluate early outcomes of transthoracic pulmonary valve implantation for the treatment of moderate and severe pulmonary regurgitation by using homemade self-expanding valve (SalusTM). Methods Patients with severe pulmonary regurgitation who underwent transthoracic pulmonary valve implantation in Guangdong Provincial People’s Hospital from September 2, 2021 to November 25, 2022 were prospectively enrolled. The early postoperative complications and improvement of valve and heart function were summarized and analyzed. Results A total of 25 patients were enrolled, including 16 males and 9 females, with an average age of 24.5±1.5 years and an average weight of 57.0±3.0 kg. The mean systolic diameters of the bifurcation near the main pulmonary artery, the stenosis of the middle segment of the aorta and near the valve of the right ventricular outflow tract of the patients were 31.8±7.4 mm, 30.6±5.9 mm and 38.4±8.0 mm, respectively. All patients were successfully implanted with valves, and there were no serious complications such as death, coronary compression, stent fracture, valve displacement and infective endocarditis in the early postoperative period. The indexed left atrial longitudinal diameter, indexed right atrial longitudinal diameter, and indexed right ventricular outflow tract anteroposterior diameter decreased significantly after the operation. The degree of tricuspid and pulmonary valve regurgitation and the indexed regurgitation area decreased significantly. The above differences were statistically significant (P<0.05). Conclusion The early outcomes of transthoracic pulmonary valve implantation with homemade self-expanding pulmonary valve (SalusTM) in the treatment of severe pulmonary regurgitation is relatively good, and the long-term outcomes need to be verified by the long-term follow-up studies with large samples.

Objective To develop a novel transcatheter tricuspid valve replacement device and test its performance. Methods The transcatheter tricuspid valve stent consisted of double-layer self-expanding nitinol stent, biotissue-derived bovine pericardial leaflets, and PTFE woven. The delivery system, mainly consisting of a handle control unit and a delivery sheath, was sent to the correct position via right atrium or jugular vein. The sheath had a visualization feature, and the handle control unit could realize the functions of stable release and partial recovery of the interventional valve. In addition, this study performed animal survival experiments on the basis of in vitro experiments. A large-white pig was used as the experimental animal. Cardiopulmonary bypass was established through median thoracotomy, then the right atrium was opened, and the interventional valve was released under direct vision without cardiac arrest. Approximately 1 month after interventional valve implantation, the maneuverability and stability of the interventional tricuspid device were evaluated by autopsy. Results Through the animal experiment, the interventional valve was successfully released, and the anchoring was satisfactory. Postoperative transthoracic echocardiography showed that the interventional valve opened and closed well, the flow rate of tricuspid valve was 0.6 m/s, and there was no obvious tricuspid regurgitation. One month after the operation, we dissected the large-white pig and found the interventional valve was not deformed or displaced, the leaflets were well aligned, and there was thrombus attachment in the groove between the inner and outer layers of the interventional valve. Conclusion Animal experiment shows that the novel device can stably and firmly attach to the tricuspid annulus, with good anchoring effect, and effectively reduce paravalvular leakage.

Intervertebral disc degeneration(IDD) is the pathological basis of spinal diseases. With the development and change of working and living style, IDD gradually presents the trend of younger in recent years. The effective prevention and treatment of IDD has become a hotspot in clinical research. Recent studies have shown that oxidative stress plays an important role in IDD. The disruption of reactive oxygen species balance in cells or the body leads to changes in extracellular matrix and intervertebral disc cell phenotype, which induces oxidative stress of intervertebral disc and leads to IDD. Oxidative stress can affect the development of IDD through apoptosis, autophagy, senescence and extracellular matrix of intervertebral disc. Currently, opioids and drugs for promoting blood circulation and pain relief are commonly used in clinical treatment of IDD, which can alleviate some symptoms to a certain extent, but is easy to induce gastrointestinal and other adverse reactions. Meanwhile, due to the long treatment cycle and poor patient compliance to a certain extent, which brings great difficulties to the treatment. At the same time, traditional Chinese medicine plays an important role in the treatment of IDD due to its advantages of low cost and fewer adverse reactions. With the in-depth research of modern technologies such as molecular biology and network pharmacology, it has been found that traditional Chinese medicine can intervene in the expression of oxidative stress-related functions, namely, slowing down apoptosis, autophagy and degradation of extracellular matrix, etc, to play a role in the treatment of IDD. In this paper, the role of oxidative stress in IDD and the research results on the intervention of traditional Chinese medicine in oxidative stress will be expounded, in order to provide reference for the prevention and treatment of IDD by traditional Chinese medicine.

Objective:To evaluate the 10-year protective effect and immunogenicity of quadrivalent human papillomavirus (HPV) vaccine in Chinese women aged 20 to 45 years.Methods:From October 2019 to April 2020, a long-term follow-up study was conducted on the subjects of the Phase III clinical trial of the quadrivalent HPV vaccine (NCT00834106). Participants underwent a questionnaire survey, venous blood sampling, gynecological examination, cervical exfoliated cell pathology examination, and serum neutralizing antibody titers for HPV-6, 11, 16, and 18 were measured using a pseudovirus neutralization assay. The results of the cytological examination and the positive rate and titers of serum antibodies of different cervical exfoliated cells were compared.Results:A total of 889 subjects were followed up, including 240 in the control group, 453 in the vaccination group and 196 in the post-trial vaccination group. The age of the control group was (40±7) years old, which was higher than that of the supplementary vaccination group and the vaccination group [(38±4) and (38±6) years old, respectively] ( P<0.05). There were no statistically significant differences in condom use and sexual frequency among all groups (all P values>0.05). The abnormal proportion of cervical exfoliation cytopathology in the vaccination group was 3.7% (17/453), which was significantly lower than that in the control group [9.6% (23/240)] and post-trial vaccination group [5.6% (11/196)] ( P<0.05). There were two cases of cervical intraepithelial neoplasia (CIN) grade 1 in the vaccination group, two cases of CIN grade 1 and three cases of CIN grade 2 and above in the control group, and no CIN grade 1 and above cases in the post-trial vaccination group. The positive rate of HPV-18 antibody was 35.5% (161/453) in the vaccination group and 76.0% (149/196) in the post-trial vaccination group, which was significantly lower than that of other types ( P<0.05). The neutralizing antibody GMT ratio between the vaccination group and the control group ranged from 2.62 to 25.33 (9.05 to 83.08). Conclusion:Protective neutralizing antibodies are sustained in Chinese women aged 20 to 45 years after ten years of vaccination with quadrivalent HPV vaccine.

Objective:To evaluate the calf muscle cross-sectional area (CSA) and fat fraction (FF) in amateur marathon runners based on T 2WI-Flex fat-suppression sequence and iterative decomposition of water and fat with echo asymmetrical and least-squares estimation quantitation sequence (IDEAL-IQ) technique, and to explore the correlation between them and age, body mass index (BMI), running age, speed exercise, and monthly exercise. Methods:From September to November 2022, 37 amateur marathon group (marathon group) and 12 healthy volunteers (control group) who did not often exercise were recruited in Shijiazhuang. T 2WI-Flex fat-suppression sequence and IDEAL-IQ sequence were performed on all subjects. The anterior group of the right calf (tibialis anterior, extensor hallucis longus, extensor digital longus), external group of the calf (peroneus longus, peroneus brevis), soleus, medial head and lateral head of the gastrocnemius were delineated along the edge of the muscle contour as regions of interest, and the CSA and FF values of the muscles were obtained. Twelve subjects matched with the clinical data of the control group were selected from the marathon group (marathon matched group), and the differences in CSA and FF were compared by independent sample t test or Mann-Whitney U test. Spearman correlation analysis was used to evaluate the correlation between CSA and FF values of the right calf and running-related indicators including age, BMI, running age, speed exercise, and monthly exercise in 37 amateur marathon runners. Results:The CSA of the right calf soleus muscle in the marathon matched matched group was larger than that in the control group ( t=-2.09, P=0.048). There was no significant difference in CSA of other calf muscles between the two groups ( P>0.05). The FF values of the right calf anterior group, the outer group, the soleus muscle, the medial head and the lateral head of the gastrocnemius muscle in the marathon matched group were lower than those in the control group ( P<0.05). The BMI of 37 amateur marathon runners was positively correlated with the CSA and FF values of the anterior group, the outer group, the soleus, the medial head and the lateral head of the gastrocnemius muscle (CSA: r=0.628, 0.468, 0.680, 0.566, 0.615, respectively, all P<0.05; FF value: r=0.395, 0.567, 0.631, 0.482, 0.516, respectively, all P<0.05). The FF values of the anterior group, the outer group, the soleus, the medial head and the lateral head of the gastrocnemius muscle were negatively correlated with monthly exercise ( r=-0.337, -0.405, -0.437, -0.338, -0.446, respectively, all P<0.05). Conclusions:Long-term running training can reduce the FF value of each calf muscle group, and the FF value of calf muscles is negatively correlated with the amount of running each month. Long-term running training has the greatest effect on the CSA of soleus muscle.

Intervertebral disc degeneration is one of the common causes of chronic low back pain. As a common spinal disease， its clinical symptoms are mainly low back pain and limited function， which seriously affects physical and psychological health. Because of its complex and unclear pathogenesis， the treatment of intervertebral disc degeneration has been the focus of scientific researchers and clinical workers. At present， the treatment of intervertebral disc degeneration mainly includes non-surgical therapy and surgical therapy， which can alleviate the clinical symptoms of patients to a certain extent， but easily induce new complications， and it is difficult to restore the normal physiological function of the intervertebral disc. In recent years， along with the advanced research on matrix metalloproteinases （MMPs） in the tissues of intervertebral disc degeneration， it has been found that MMPs can be used as molecular therapeutic targets. The expression of MMPs in the intervertebral disc tissues can be regulated by reducing the content and composition of the extracellular matrix of the intervertebral disc， so as to slow down intervertebral disc degeneration and even reverse the occurrence of intervertebral disc degeneration. This treatment is expected to delay intervertebral disc degeneration caused by changes in extracellular matrix composition or content. In recent years， with the continuous development of network pharmacology and bioinformatics research， a large number of researchers have explored the treatment of intervertebral disc degeneration by traditional Chinese medicine （TCM） and found that TCM can reduce the degradation of extracellular matrix by inhibiting the expression of MMPs， thus alleviating the symptoms of intervertebral disc degeneration and slowing down the progression of intervertebral disc degeneration. This paper reviewed the research progress of TCM intervention in MMP expression in the treatment of intervertebral disc degeneration， aiming at providing references for the application of TCM in the prevention and treatment of intervertebral disc degeneration.
