Immunotherapy, including immune checkpoint inhibitors, tumor vaccine therapy, oncolytic virotherapy, and adoptive cell therapy, has made remarkably breakthroughs in the field of oncology. Immune checkpoint inhibitors, which block programmed death receptor 1 or programmed death ligand 1, have been included in the first-line clinical treatment for advanced solid tumors, such as non-small cell lung cancer and malignant melanoma. However, primary or secondary drug resistance in tumors severely limits the survival benefits for patients. Immune-related adverse reactions, such as pneumonia, hypothyroidism, hypophysitis, and myocarditis, also greatly affect the quality of life of patients. Fuzheng Jiedu Huayu is an important concept guiding the prevention and treatment of tumors with traditional Chinese medicine (TCM). It is also a curative principle and therapeutic TCM method to reduce the toxicity and enhance the efficacy of immunotherapy. This article summarizes the research progress of immunotherapy and discusses how TCM reduces the toxicity and enhances the efficacy of immunotherapy, hoping to provide a reference for the integrated treatment of tumors with TCM and immunotherapy.

Esophageal squamous cell carcinoma(ESCC)is a common malignant tumor with insidious early symptoms and a poor prognosis.In traditional Chinese medicine(TCM),ESCC is classified as"ye ge."Drawing on clinical experience,we believe that kidney deficiency leads to the deficiency of vital qi and immune dysfunction,providing the foundation for cancerous growth by depleting qi and damaging essence,toxic stasis and stagnation,forming a local hypoxic and acidic microenvironment that promotes tumor invasion,metastasis,and recurrence.Considering the effect of modern comprehensive treatments,the occurrence and development of ESCC are summarized as kidney deficiency being the root cause and toxic stasis being the driving force.The pathogenesis and treatment of ESCC in the preoperative,postoperative,and non-surgical treatment stages are discussed.The pathogenesis of the disease is summarized as follows:preoperatively,toxicity and stasis intertwine,depleting the kidney;postoperatively,the kidney loses its vitality,allowing various pathogenic factors to persist;during non-operative treatment,vital qi and pathogens contend,resulting in entrenched toxicity.During the preoperative neoadjuvant phase,therapy should resolve stasis,eliminate toxins,enhance kidney function,tonify essence,and support the body.During the postoperative adjuvant phase,therapy should strengthen the root and consolidate the foundation while detoxifying and expelling stasis.The non-surgical treatment stage uses"balanced interruption,"targeting tumor progression and metastasis by harmonizing yin and yang,thus preventing recurrence.This article will provide insights into the integrative Chinese-Western management of ESCC.

Objective:To evaluate the safety of leadless pacemaker implantation in super-elderly patients.Methods:Eleven patients with average age of 90 (86, 92) years who underwent leadless pacemaker implantation in the Department of Cardiology, Peking University People′s Hospital from March 2021 to May 2022 were included. The clinical data and implantation information were collected. The complications (cardiac tamponade, myocardial infarction, cerebral infarction, pulmonary embolism, pacemaker reinfection, femoral vein hematoma) and death of patients were documented at 24 h, 3 d, and 1, 3, 6 months after pacemaker implantation.Results:There were 9 males and 2 females with the body mass index of 21(19, 23)kg/m 2. The underlying diseases were hypertension, diabetes, coronary heart disease, chronic kidney disease, chronic obstructive pulmonary disease, previous cerebral infarction and moderate to severe tricuspid regurgitation in 9, 9, 9, 6, 4, 4, 4 patients, respectively. The left ventricular ejection fraction was 49% (45%, 52%), the hemoglobin concentration was 118 (114, 122)g/L, 4 patients were taking anticoagulant drugs, and 6 patients were taking antiplatelet drugs. Eight patients were newly implanted with a leadless pacemaker, 2 patients were implanted after removal the old ones, and 1 case was implanted at the same time as removal. The implantation time was 45(40, 47) minutes, the X-ray exposure time was 14 (13, 15) minutes, the release time was 1 (1, 2), the threshold value was 0.50(0.38, 0.75)V/0.24 ms, the impedance was 730 (700, 770) Ω, and the perceived R-wave amplitude 8.2(6.7, 12.8) mV. During the follow-up period of 8 (6, 10) months, no patient had pacemaker dysfunction; and the threshold, R wave sensing, and impedance were stable and maintained within the normal range. No cardiac tamponade, myocardial infarction, cerebral infarction, pulmonary embolism, pacemaker reinfection or death occurred perioperatively and during the follow-up period; 1 patient had hematoma after femoral vein puncture, which improved after compression treatment. Conclusion:This single-center and small-sample study shows that leadless pacemaker implantation is safe for super-elderly patients.

Objective::Data comparing the outcomes of MiStent (Micell Technologies, Durham, North Carolina, USA) microcrystalline biodegradable polymer (BP) drug-eluting stent (DES) and those of another post-marketing BP-DES, TIVOLI (EssenTech, Beijing, China) are rare. This study sought to compare the angiographic efficacy and clinical outcomes of the microcrystalline BP sirolimus-eluting stent (SES) system MiStent and those of TIVOLI BP-SES.Methods::The DESSOLVE-C trial was a prospective, single-blinded, multicenter, randomized trial (NCT02448524), which randomly assigned patients with de novo coronary lesions to receive MiStent or TIVOLI BP-SES by a 1:1 ratio. The primary endpoint was a non-inferiority comparison of in-stent late lumen loss (LLL) by quantitative coronary angiography at 9 months. The secondary endpoint was device-related clinical cardiovascular composite events (target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction (MI), and clinically driven target lesion revascularization) and 1-year outcomes. Results::A total of 428 patients (216 patients in the MiStent group and 212 patients in the TIVOLI group) were enrolled and included in an intention-to-treat analysis. MiStent was not only non-inferior but superior to TIVOLI for in-stent LLL at 9 months ((0.23 ± 0.37) mm vs. (0.34 ± 0.48) mm, P for non-inferiority <0.001, P for superiority = 0.02). Although without significant difference, the rate of TLF in MiStent was quantitatively lower than that in TIVOLI (3.70% vs. 6.60%; P = 0.17). Conclusion::Compared with TIVOLI BP-SES, the MiStent system was superior in in-stent LLL at 9 months and had a comparable clinical benefit at 1 year in de novo coronary lesions.

Objective:To identify the prevalence of multimorbidity among a Chinese population, analyze the risk of all-cause mortality with different multimorbidity patterns, and the impact of exercise on the risk of multimorbidity-related mortality and life lost.Methods:The study was based on 437 408 MJ Health Management Center participants. The classification decision tree was used to explore multimorbidity patterns composed of hypertension, diabetes, chronic kidney disease (CKD), and chronic obstructive pulmonary disease (COPD). The Cox proportional hazards model was used to calculate the all-cause mortality hazard ratio ( HR) for different multimorbidity patterns. Using Chiang's life table method, years of life lost were the difference in life expectancy for those with and without multimorbidity. Results:The prevalence rate of multimorbidity was 8.7%. Among multivariate patterns, the most common ones were "hypertension+CKD" (3.6%), "hypertension + diabetes + CKD" (1.1%) and "hypertension+diabetes+CKD+COPD" (0.1%). Compared with a healthy population, patterns with the highest mortality risk were "diabetes+CKD" ( HR=3.80, 95% CI: 3.45-4.18), "diabetes+CKD+COPD" ( HR=4.34, 95% CI: 3.43-5.49) and "hypertension+ diabetes+CKD+COPD" ( HR=4.75,95% CI:4.15-5.43). Through low-intensity and moderate to high-intensity exercise, the increased HRs were attenuatedcompared with the inactive population. People with single disease and multimorbidity shortened life by 4.6 and 13.4 years, while exercise attenuated 2.3 and 4.6 years of life lost, of which low-intensity and moderate to high-intensity exercise saved 1.5 and 3.7 years of life lost due to chronic diseases. Conclusions:Multimorbidity patterns based on "diabetes + CKD" cause the highest mortality risk, and physical activity in reducing mortality was significant for either with or without multimorbidity. Higher exercise intensity leads to a greater relative reduction of mortality risk.
