The comprehensive diagnosis and treatment of advanced breast cancer has entered the era of "accurate classification and precise stratification", and is moving towards the road of personalized precision medicine. In 2023, significant breakthroughs have been achieved in the research on different molecular classifications of advanced breast cancer, influencing clinical guidelines and transforming clinical practice. The primary focus of research for hormone receptor positive advanced breast cancer lies in selecting appropriate treatments for patients who have failed cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors. Advanced breast cancer with low human epidermal growth factor receptor 2 (HER2) expression has emerged as a promising treatment direction, with T-DXd being an important therapeutic option. With the release of results from the PHILA study, a new era has begun for first-line treatment of HER2-positive advanced breast cancer. Simultaneously, T-DXd has become the preferred choice in clinical practice following tyrosine kinase inhibitor failure. Research related to immune and targeted therapy for advanced triple-negative breast cancer (TNBC) is also progressing rapidly, yielding positive outcomes in studies such as TORCHILIGHT and BEGONIA. Additionally, ongoing clinical studies on precision treatment based on the "Fudan classification" for TNBC are expected to revolutionize current treatment approaches. This paper summarized major advancements in clinical research on advanced breast cancer in 2023 according to various molecular classifications, aiming to provide improved reference and guidance for clinical management.

Taking A-share listed companies in China from 2010 to 2020 as research samples, the impact of foreign institutional investors’ shareholding ratio on corporate social responsibility is explored, and internal control is used as an intermediary variable and institutional environment as a moderating variable to further verify the internal mechanism between foreign institutional investors’ shareholding ratio and corporate social responsibility. The results indicate that there is a significant positive correlation between the shareholding ratio of foreign institutional investors and corporate social responsibility, enterprises’ internal control can play a mediating role between the two, and the institutional environment has a certain moderating effect on the relationship between the shareholding ratio of foreign institutional investors and corporate social responsibility.

FeCr nano alloy powder was prepared by electric explosion, and the effects of different discharge voltage and wire diameter on the particle size and distribution of the powder were investigated. The results show that with the increase of discharge voltage and the decrease of wire diameter, the particle size of nano powder decreases and the particle size distribution narrows gradually under the premise that the process parameters such as pressure and cooling temperature inside the equipment remain unchanged. In this study, when the discharge voltage is 16 kV and the diameter of the metal wire is 0.2 mm, the FeCr nano alloy powder prepared shows better performance. The powder was smooth and spherical, the particle size was basically below 100 nm, and the average particle size was only 57.87 nm. The content of Fe, Cr, O was basically the same as that of FeCr alloy wire, and the phase structure was mainly Fe-Cr alloy phase. [ABSTRACT FROM AUTHOR]

The experiment was to investigate effect of providing forage to calves at early age with straw bedding on growth performance, rumen performance and ruminating duration of calves. 30 newborn Holstein female calves with similar birth weight of (36.7±1.8) kg were randomly divided into two groups, with 15 replicates in each group. The experiment lasted for 82 d. Calves in concentrate group were provided with free access to pellet starter, calves in forage group were provided with free access to pellet starter and oat hay separately. The results showed that there was no significant difference between groups in terms of height of calves, TDMI, ADG, FE, total production of VFA in rumen, the proportion of each VFA, ammonia-N and ruminating duration during pre-weaning period, post-weaning period and whole trail ( P >0.05). Chest circumference of calves in concentrate group was significantly higher than that in forage group ( P <0.05). The CDMI of calves in forage group was extremely lower than that in concentrate group ( P <0.01). The experiment indicates that providing forage to calves at early age has no influence on growth performance, rumen fermentation and ruminating duration, but increase chest circumference of calves significantly and decrease the CDMI.

Fine diameter spherical titanium alloy powder for 3D printing selective laser melting (SLM) was prepared by induction plasma spheroidization with irregular TC4 titanium alloy powder as raw material. The powder morphology and particle size were characterized via scanning electron microscope (SEM) and laser particle size analyzer, respectively. It indicates that the particle size of raw material, powder feeding rate and plasma power have important effects on the spheroidization rate and surface state of titanium alloy powder after spheroidizing. On the premise of the same other process parameters, the surface state of spherical titanium alloy powder is not optimal if the powder feeding rate is too low or the plasma power is too high;the sphericity of spherical titanium alloy powder is not optimal if the powder feeding rate is too high or the plasma power is too low. According to the influence law, optimum technological parameters were selected and plasma power was confirmed to be 14 kW. The basic properties of the spherical titanium alloy powder were characterized. The particle size of spherical titanium alloy powder was mainly distributed in the range of 20--50 pm, accounting for 95. 62%. The total impurity content of Fe and O was 0. 51 %,; The bulk density, tap density and fluidity were 2. 40 g/cm3,2. 68 g/cm3 and 38 s/50 g respectively. The product performance meets the requirements of SLM process. [ABSTRACT FROM AUTHOR]
