Objective To observe the effects of cultivation mode of autonomous learning ability in TCM formula on students’ learning capacity and comprehensive quality. Methods On the basis of inheriting the traditional teaching mode, classroom questioning, class discussion, problem-based learned teaching, simulated prescription exercises, autonomous teaching and training, the mid-term oral test, and autonomous proposition consisted of autonomous learning ability training mode diversification. In the teaching process, teachers' teaching was the primary, and was interspersed with cultivation mode of autonomous learning ability. At the end of the teaching activities, questionnaire survey method was adopted to evaluate the autonomous learning ability training mode in the teaching of TCM formula. Results 81.30%-97.74% students believed that this mode is helpful to improve their learning ability and comprehensive quality; 75.87%-98.49% students believed that it is necessary to carry out the mode in the teaching activities; 69.53% students believed that conducting mid-term examination in the form of oral teat is feasible. Conclusion The cultivation mode of autonomous learning ability for TCM formula can stimulate the learning enthusiasm of the students from various angles, raise interest in learning, arouse students’ learning enthusiasm and initiative, and further cultivate autonomous learning ability and clinical thinking ability, which can provide references for the teaching reform of TCM formula.

We report the successful treatment of mitral regurgitation by remote robotic transcatheter edge-to-edge repair(TEER)under pure transesophageal echocardiographic guidance in a 70-year-old male patient with severe mitral regurgitation due to ischemic cardiomyopathy.The patient showed no significant improvement after coronary interventional treatment and guideline-directed medical therapy before TEER.Following a multidisciplinary discussion,a TEER procedure was indicated and performed.The procedure utilized robotic assistance guided by echocardiography,combined with 5G communication technology,to remotely operate the surgical robot in Shenzhen from Beijing.Postoperatively,the patient's mitral regurgitation was reduced to trace,symptoms were markedly improved,there were no severe complications,and the patient was discharged five days after the operation.The integration of pure echo-guided interventional technology with remote robotic operation holds significant importance for enhancing the capabilities in treating cardiovascular diseases at the primary hospitals.

Hepatocellular carcinoma (HCC) is well characterized as a heterogeneous disease. Its late-stage diagnosis and chemotherapy resistance make it one of the refractory tumors in China. Natural killer (NK) cells play a significant role in immune surveillance. However, NK cells become dysfunctional in the progression of HCC, leading to tumor immune escape. This article reviews the recent progress on different strategies of NK cell-based immunotherapy in treating HCC, including direct adoptive NK cell transfer, gene engineering in NK cell, NK cell receptor targeting, immunosuppressive microenvironment modification, and tumor toxicity enhancement by cytokines or traditional Chinese medicine. These NK cell-based strategies have shown promising therapeutic potential.

Natural killer (NK) cells, a type of cytotoxic lymphocytes, can infiltrate into ischemic brain and exacerbate neuronal cell death. Astragaloside IV (ASIV) is the major bioactive ingredient of Astragalus membranaceus, a Chinese herbal medicine, and possesses potent immunomodulatory and neuroprotective properties. This study investigated the effects of ASIV on post-ischemic brain infiltration and activation of NK cells. ASIV reduced brain infarction and alleviated functional deficits in MCAO rats, and these beneficial effects persisted for at least 7 days. Abundant NK cells infiltrated into the ischemic hemisphere on day 1 after brain ischemia, and this infiltration was suppressed by ASIV. Strikingly, ASIV reversed NK cell deficiency in the spleen and blood after brain ischemia. ASIV inhibited astrocyte-derived CCL2 upregulation and reduced CCR2
