Antitumor drugs are considered pathogenic toxin-attacking agents， whose intense and biased pharmacological effects on the body may induce secondary pathological factors and subsequent pathological changes， that is， drug toxin. Its pathogenic features include rapid and marked impairment of healthy qi and constitution-dependent transformation. Zang-fu （脏腑） organs involvement is characterized by an early response of the middle jiao （焦）， later involvement of the kidney and marrow， and extension to the five zang organs， while its temporal evolution may manifest as acute injury， cumulative injury， and persistent or delayed injury. Cancer toxin， drug toxin， and deficiency of healthy qi interact to form a dynamically evolving complex pathogenic pattern. Clinically， treatment should take disease stage as the framework， toxin differentiation as the focus， and reinforcement of healthy qi as a principle throughout the course， while coordinating toxin reduction and elimination of cancer toxin with reinforcement of healthy qi. Furthermore， intervention against drug toxin should be initiated early and throughout the entire course of antitumor therapy. This framework may provide a theoretical basis for integrating traditional Chinese medicine throughout comprehensive cancer treatment.

BACKGROUND: Pre-transplant exposure to immune checkpoint inhibitors (ICIs) significantly increases the risk of allograft rejection after liver transplantation (LT); however, whether ICI-related rejection leads to increased graft loss remains controversial. Therefore, this study aimed to investigate the association between ICI-related allograft rejection and perioperative graft loss. METHODS: This was a retrospective analysis of adult liver transplant recipients with early biopsy-proven T-cell-mediated rejection (TCMR) at Liver Transplantation Center of Sun Yat-sen Memorial Hospital from June 2019 to September 2024. The pathological features, clinical characteristics, and perioperative graft survival were analyzed. RESULTS: Twenty-eight patients who underwent early TCMR between June 2019 and September 2024 were included. Based on pre-LT ICI exposure, recipients were categorized into ICI-related TCMR (irTCMR, n = 12) and conventional TCMR (cTCMR, n = 16) groups. Recipients with irTCMR had a higher median Banff rejection activity index (RAI) (6 vs . 5, P = 0.012) and more aggressive tissue damage and inflammation. Recipients with irTCMR showed higher proportion of treatment resistance, achieving a complete resolution rate of only 8/12 compared to 16/16 for cTCMR. Graft loss occurred in 5/12 of irTCMR recipients within 90 days after LT, with no graft loss in cTCMRs recipients. Cox analysis demonstrated that irTCMR with an ICI washout period of <30 days was an independent risk factor for perioperative graft loss (hazard ratio [HR], 6.540; 95% confidence interval [CI], 1.067-40.067, P = 0.042). CONCLUSION IrTCMR is associated with severe pathological features, increased resistance to treatment, and higher graft loss in adult liver transplant recipients.

Based on the theory of circulation of qi,a theoretical model of the circulation of phase fire in the human body was con-structed.It is proposed that cancer toxicity is the key factor that triggers the disorder of phase fire and hinders the circulation of phase fire.The disorder of phase fire and poor circulation are important pathogenesis of the occurrence and development of cancer toxicity.With the principle of strengthening healthy qi and eliminating evil qi,the Wenzi Jiedu method is used to treat tumors,which plays an important role in warming and nourishing,regulating yin and yang,and eliminating cancer toxicity.The combination of war-ming,nourishing and detoxification can promote the return of the phase fire and make the human body's generation and transformation active,providing a new treatment idea for TCM diagnosis and treatment of tumors with mainly cold poison or mixed cold and heat.

In recent years, traditional Chinese medicine (TCM) has made great progress in the prevention and treatment of cancer. It has gradually revealed its characteristics and advantages in clinical practice, including alleviating clinical symptoms, prolonging survival time, decreasing the adverse effects of chemotherapy, and improving living quality. However, clinical TCM treatment of cancer lacks systematic theoretical guidance, because ancient TCM has not formed a recognized theoretical system of cognitive cancer, and there still are different opinions on the pathogenesis of cancer. Due to the complexity of cancer, the essence of cancer pathogenesis has not been described accurately by using common pathogenic factors, such as pathogenic wind, cold, dampness, summer heat, dryness, and fire. Ancient and modern TCM physicians have a similar understanding that the occurrence of cancer is related to toxin. In the 1990s, the thought of cancerous toxin was first proposed by Prof Zhou Zhongying, a TCM master based on more than 60 years of clinical practice, who used “pandemic Qi (Li-Qi) is a specific pathogenic factor of epidemic disease” in Wenyi Lun (Treatise on Pestilence) for references. The pathogenesis theory of cancerous toxin was gradually established under the guidance of the thought of cancerous toxin. It holds that the cancerous toxin, a special pathogenic factor of cancer, is the key pathogenesis of the occurrence of malignant tumors. According to the pathogenesis theory of cancerous toxin, the basic pathogenesis of malignant tumors is the accumulation of pathogenic factors and cancerous toxin, and the deficiency of the vital Qi (Zheng-Qi). Therefore, the treatment principle involves eliminating pathogenic factors, resolving cancerous toxin, and supporting the vital Qi. The anticancer detoxification methods and the classification of Chinese medicinal herbs with anticancer detoxification effects were put forward. System theory has much in common with the concepts in the theory system of TCM, such as the universal relation theory, asking for a concrete analysis of concrete conditions, the humanism thought, and so on. This article aims to describe, review, and analyze the pathogenesis theory of cancerous toxin based on system theory for clinical practices.

OBJECTIVETo compare the components and contents of volatile oil in Gardenia jasminoids, Zingiber officinale, G. jasminoids roasted with ginger juice and to provide scientific basis for intrinsic material of G. jasminoids roasted with ginger juice.

METHODThe volatile oil in the three herbal medicines was extracted by steam distillation, the components were analyzed by GC-MS and the contents of the components were calculated by area normalization method.

RESULTThe contents of volatile oil in G. jasminoids, Z. officinale, G. jasminoids roasted with ginger juice were 1.0, 2.0, 1.5 microL x g(-1), respectively. A total of 89 components were identified by GC-MS. Although 42, 75 and 77 peaks were separated, only 30, 58 and 67 components were identified accordingly, which accounted 94.1%, 90.52% and 94.38% of the whole volatile oil.

CONCLUSIONAfter being processed with ginger juice, the components and contents of volatile oil in G. jasminoids has been changed obviously.

Objective To consider the clinical significance of retroperitoneal laparoscopic adrenalectomy for adrenal diseases. Methods We analyzed 33 cases of adrenal diseases treated by retroperitoneal laparoscopic adrenalectomy in this hospital from October 1996 to December 2001. Results Retroperitoneal laparoscopy was successfully applied in 31 cases, whereas conversions to open adrenalectomy were required in the other 2 cases. The mean operation time was 158 min (120 min～200 min). The mean intraoperative blood loss was 150 ml, without blood transfusion needed. The mean length of hospital stay was 6.4 days. Conclusions Compared with open surgery, retroperitoneal laparoscopic adrenalectomy has the advantages of minimal invasion, less blood loss, fewer complications, quicker recovery and shorter hospital stay length. This procedure can be applied to in the absence of contraindications (such as tumor size being more than 10cm, metastatic carcinoma and vital organs or blood vessels being involved).
