By reviewing the research history on quality comparison between wild and cultivated Chinese crude drugs, this paper systematically combed the relevant research reports since the 1950s, and summarized and analyzed the results of existing comparative studies, and found that the existing comparative research on the quality of wild and cultivated Chinese crude drugs were mainly focused on several aspects, including characteristics, microstructures, chemical compositions, pharmacodynamic effects, and genetic diversity. Among these, comparative studies of chemical compositions have been the dominant approach, with a particular emphasis on comparing the contents of index components. However, research on pharmacodynamic effects remained relatively limited. Due to various factors such as sample quantity, sample origin, growth period and cultivation methods, the differences in quality between wild and cultivated Chinese crude drugs vary significantly. In general, most wild Chinese crude drugs exhibited higher quality than cultivated products, with significant differences in their characteristics. The contents and proportions of some chemical components underwent noticeable changes, particularly with a marked increase in the proportion of primary metabolites after cultivation. The quality of cultivated Chinese crude drugs is closely related to the cultivation practices employed. Chinese crude drugs produced through wild nurturing, simulated wild planting, ecological cultivation, and other similar methods demonstrate quality levels comparable to those of wild Chinese crude drugs. Based on the analysis results, it is recommended to explicitly specify the cultivation practices and cultivation period of cultivated Chinese crude drugs in comparative studies of the quality between wild and cultivated Chinese crude drugs. Multiple technical approaches, including characteristics, microscopy, non-targeted metabolomics combined with quantitative analysis of differential components, and bioefficacy evaluation, should be employed to comprehensively assess the quality disparities between wild and cultivated Chinese crude drugs. Moreover, research efforts should be intensified to investigate the changes in pharmacodynamic effects resulting from differences in plant cell wall composition, primary metabolites, and secondary metabolites, in order to guide the production of high-quality Chinese crude drugs.

Breast cancer, a malignant tumor with a high incidence in women, lacks in vitro research models that can represent the biological functions of breast tumors in vivo. As a new biological tool, the organoid model has unique advantages over traditional methods, such as cell culture and patient-derived xenografts. Combining organoids with other emerging technologies, such as gene engineering and microfluidic chip technology, provides an effective method to compensate for the deficiencies in organoid models of breast cancer in vivo. The emergence of breast cancer organoids has provided new tools and research directions in precision medicine, and drug research. In this review, we summarized the merits and demerits of organoids compared to traditional biological models, explored the latest developments in the combination of new technologies and organoid models, and discussed the construction methods and application prospects of different breast cancer organoid models.

Enhanced recovery after surgery (ERAS) is mainly based on evidence-based medicine to implement a series of measures to optimize perioperative management, reduce patients′ physiological and psychological trauma stress during perioperative period, reduce patients′ functional damage and promote patients′ functional recovery, so as to achieve rapid rehabilitation. ERAS has been widely used in clinic and achieved good clinical results. However, it still faces a series of problems that need further research to clarify the clinical path of ERAS required by different patients and different surgical methods. In particular, it is necessary to strengthen the research on risk factors of ERAS, minimally invasive surgery, goal-directed fluid therapy, anesthesia and postoperative pain management technology, pre rehabilitation and postoperative rehabilitation technology, and implement ERAS guided by the best outcome in the perioperative period.

Objective:To evaluate the modified efficacy of thoracic paravertebral block (TPVB) combined with general anesthesia in the patients undergoing laparoscopic radical nephrectomy.Methods:Eighty patients, aged 38-64 yr, with body mass index of 18-24 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective laparoscopic radical nephrectomy, were selected and randomly divided into 2 groups ( n=40 each) using a random number table method: general anesthesia group (group GA) and TPVB combined with general anesthesia group (group TPVB+ GA). A paravertebral catheter was placed at T 8 and T 10 under ultrasound guidance before induction of anesthesia, and 0.5% ropivacaine 10 ml was administered via the catheter in group TPVB+ GA.Anesthesia was induced with propofol, sufentanil, etomidate and rocuronium and maintained by intravenous infusion of propofol and remifentanil.Patient-controlled intravenous analgesia was performed with sufentanil, ketorolac tromethamine and tropisetron at the end of surgery.When postoperative visual analog scale score≥4, tramadol 50 mg was intravenously injected as rescue analgesic.Immediately before anesthesia induction (T 0), at 5 min after establishing pneumoperitoneum (T 1), at 2 h of pneumoperitoneum (T 2), and immediately after the end of pneumoperitoneum (T 3), and at 24 h after operation (T 4), venous blood samples were collected for determination of plasma norepinephrine concentrations (by enzyme-linked immunosorbent assay), plasma cortisol level (using radioimmunoassay), and blood glucose concentrations were measured.The intraoperative consumption of sufentanil and remifentanil was recorded.The intraoperative hypertension, hypotension, and bradycardia were recorded, and the nausea and vomiting, pruritus, and requirement for rescue analgesia occurred within 24 h after surgery were recorded. Results:Compared with group GA, the plasma concentrations of norepinephrine, cortisol and blood glucose were significantly decreased at T 1-4, the intraoperative consumption of sufentanil and remifentanil was reduced, and the postoperative requirement for rescue analgesia was decreased in group TPVB+ GA ( P<0.05). There was no significant difference in the incidence of intraoperative and postoperative adverse reactions between the two groups ( P>0.05). Conclusion:TPVB combined with general anesthesia is helpful in carrying out the anesthetic model of low-consumption opioids and is more helpful in inhibiting intraoperative and postoperative stress responses and postoperative pain responses than general anesthesia alone when used for laparoscopic radical nephrectomy.
