This article explores the application of Professor Zhou Zhongying's"focus on the core pathogenesis"concept in the con-text of epidemic hemorrhagic fever and examines how Academician Tong Xiaolin has inherited and developed Professor Zhou's experi-ences.Influenced by Professor Zhou Zhongying's academic thoughts and considering the contemporary context,Academician Tong Xia-olin,drawing on years of clinical experience,has proposed a new set of Nineteen Pathogenic Factors.Building upon the foundation of the Nineteen Pathogenic Factors in the The Yellow Emperor's Inner Classic,this new framework enriches and expands the understanding of disease location,etiology and pathogenesis,disease classification,and pays attention to a comprehensive understanding of diseases.It emphasizes that the process of seeking the underlying mechanisms should be approached from three aspects:dynamic,state,and condition,rather than solely focusing on the immediate clinical manifestations.This comprehensive approach to understand-ing disease development offers a fresh perspective and contributes to the application of traditional Chinese Medicine in the diagnosis and treatment of modern diseases.

Objective To explore the clinical efficacy and safety of domestic programmed death-1(PD-1)ingibitor combined with lenvatinib in the treatment of advanced hepatocellular carcinoma in the elderly.Methods The clinical data of 37 elderly patients(o-ver 60 years old)with advanced hepatocellular carcinoma,who received domestic PD-1 inhibitors combined with lenvatinib in Zhengzhou Yihe Hospital from September 2021 to July 2022 were collected.Modified Response Evaluation Criteria in Solid Tumors(mRECIST)was used to evaluate the efficacy of intrahepatic lesions,and Response Evaluation Criteria in Solid Tumors(RECIST)1.1 was used to evaluate the efficacy of extrahepatic metastatic lesions.Kaplan-Meier method was used to evaluate the survival curve.Results Among the 37 elderly patients with hepatocellular carcinoma,8 patients achieved partial response,15 patients achieved stabilization,and 14 patients a-chieved disease progression.The objective response rate and the disease control rate were 21.6％(8/37)and 62.2％(23/37),respec-tively,and the median progression-free survival time was 5.885months(95％CI:5.374-6.397 months).The overall incidence rate of treatment-related adverse events was 51.4％(19/37).The most common adverse events were fatigue 27.0％(10/37),rash 27.0％(10/37)and hypertension 21.6％(8/37).Conclusion Domestic PD-1 inhibitors combined with lenvatinib is an effective and safe therapy for elderly patients with advanced hepatocellular carcinoma.

Objective:To investigate the efficacy and safety of venetoclax combined with the decitabine, cytarabine, and homoharringtonine (HHT) regimen and donor lymphocyte infusion (DLI) for the preventive and salvage therapy of pediatric acute myeloid leukemia (AML) /myelodysplastic syndrome (MDS) after allogeneic hematopoietic stem cell transplantation (HSCT) .Methods:A total of 29 relapsed pediatric/minimal residual disease-positive AML after HSCT were recruited at the Peking University Institute of Hematology from January 1, 2021, to June 1, 2023. They were treated with the above combination regimen and administered with DLI after 24-48 hours at the end of chemotherapy, and the treatment response and adverse reactions were regularly assessed.Results:The overall response rate (ORR) was 75.8%, CR rate was 88.9% (8/9) in the hematologic relapse group, and MRD negativity rate was 61.1% (11/18) in the MRD-positive group. The incidence of agranulocytosis, anemia, and thrombocytopenia with a classification above grade 3 were 100%, 82.7%, and 100%, respectively. The median time of the granulocyte deficiency period was 15 days. Acute graft-versus-host diseases (aGVHD) with a classification of grades Ⅲ-Ⅳ occurred in 11.1% of the patients after DLI, while moderate or severe cGVHD occurred in 7.4% of the patients. The single risk factor for ORR was MNC counts of less than 10×10 8/kg, and the relapse occurred within 100 days. At a median follow-up of 406 days, the 1-year OS was 65%, and the 1-year OS was 57% in the group with no reaction ( P=0.164) compared with 71% in the group who had an overall reaction. Conclusion:The combined regimen based on the DAC, VEN, and modified HA regimen showed a high response rate in the salvage therapy for pediatric AML after the relapse of HSCT. However, bridging to transplantation should be performed immediately after remission to result in a long survival rate.

[ABSTRACT]OBJECTIVE To analyze the risk factors for relapse in patients with chronic rhinosinusitis with nasal polyps(CRSwNP)combined with asthm and provide favorable information for precise treatment and healthy prognosis of patients with CRSwNP combined with asthma.METHODS The clinical data of 161 patients with chronic rhinosinusitis with nasal polyps(CRSwNP)combined with asthm who underwent endoscopic surgery at the Department of Otolaryngology Head and Neck Surgery,Yantai Yuhuanding Hospital,affiliated to Qingdao University,from January 2016 to June 2021 were selected.Based on Lasso's Cox regression analysis and multifactorial Cox regression analysis,the associated risk factors were investigated,and the area under curve(AUC)was calculated to determine the performance of the model.Finally,the Kaplan-Meier(K-M)curves were plotted for the relevant influencing factors.RESULTS The Age[HR(95%CI):0.96(0.948-0.98),P<0.001],gender[HR(95%CI):1.94(1.21-3.14),P=0.006],tissue eosinophil percentage[HR(95%CI):1.01(1.01-1.02),P=0.004],and endoscopic nasal polyp score[HR(95%CI):0.86(0.78-0.96),P=0.005]were highly correlated with recurrence in patients with CRSwNP combined with asthma.Patients with CRSwNP combined with asthma had a higher likelihood of relapse after treatment when the tissue Eos%was>21.28%and the endoscopic nasal polyp score was>4.CONCLUSION The age,gender,tissue eosinophil percentage and endoscopic nasal polyp score are independent risk factors for disease recurrence in patients with CRSwNP combined with asthma.

Objective:To analyze and determine the clinical and genetic characteristics of children with Helsmoortel-Van der Aa syndrome(HVDAS).Methods:Clinical data of 6 children with HVDAS treated at the First Hospital of Peking University from November 2018 to October 2022 and their family members were collected and analyzed retrospectively.Whole exome sequencing was performed on children and their family members to identify the genetic variants.Genotype and phenotype correlation was analyzed.Results:(1) Clinical analysis results: among the 6 children, there were 5 boys and 1 girl, and their age at diagnosis ranged from 11 months and 17 days to 12 years and 9 months.Six patients all presented with developmental delays/intellectual disabilities; (2) Genetic analysis results: 6 de novo ADNP variants were discovered in 6 children, including 1 initial codon deletion variant c. 1_2del, 2 nonsense variants c. 1175dup, p.(Tyr392*) and c. 2213C>G, p.(Ser738*), and 3 frameshift variants c. 2632dup, p.(Ser878Lysfs*3), c.1695_1696insATGGTATGTATGTATGTATG, p.(Val566Metfs*8) and c. 2120_2123del, p.(Asn707Serfs*8).All variants were classified as pathogenic variants by the American College of Medical Genetics and Genomics.Except the c. 2213C>G, p.(Ser738*), the other 5 variants are all novel variants that have not been reported before. Conclusions:All of the 6 cases of HVDAS showed typical clinical manifestations, and expanded the phenotype spectrum of microcephaly and tall stature.Six de novo mutations were discovered, expanding the ADNP mutation spectrum and providing accurate genetic counseling and prenatal genetic diagnosis of the disease.

Traditional Chinese medicine (TCM) has played an important role in the prevention and treatment of Coronavirus disease 2019 (COVID-19) epidemic in China. The integration of Chinese and Western medicine is an important feature of Chinese COVID-19 prevention and treatment. According to a series of evidence-based studies, TCM can reduce the infection rate of severe acute respiratory syndrome coronavirus 2 in high-risk groups. For patients with mild and moderate forms of COVID-19, TCM can relieve the related signs and symptoms, shorten the period of nucleic-acid negative conversion, and reduce conversion rate to the severe form of the disease. For COVID-19 patients with severe and critical illnesses, TCM can improve inflammatory indicators and blood oxygen saturation, shorten the hospital stay, and reduce the mortality rate. During recovery, TCM can improve patients' symptoms, promote organ function recovery, boost the quality of patients' life, and reduce the nucleic-acid repositive conversion rate. A series of mechanism research studies revealed that capability of TCM to treat COVID-19 through antiviral and anti-inflammatory effects, immune regulation, and protection of organ function via a multicomponent, multitarget, and multipathway approach.

Objective To investigate the cognition of colorectal cancer-related knowledge and influencing factors of patients with middle- and advanced-stage colorectal cancer in ethnic minority areas of Inner Mongolia. Methods According to the national population and the prevalence of colorectal cancer, 277 patients with colorectal cancer were selected by stratified and random sampling in Inner Mongolia. The patients were surveyed in Baotou, Chifeng, Bayannaoer, and other hospitals. The questionnaire included patients' basic information, cognition of colorectal cancer risk factors and screening knowledge, screening information, etc. Results Before suffering from the disease, the patients' knowledge of colorectal cancer (risk factors, early screening knowledge, treatment methods) was low. About 54.9% of patients were unaware of high risk factors for colorectal cancer, 75.8% of patients did not understand the knowledge of early screening of colorectal cancer, and 37.5% of patients did not underst and the treatment of colorectal cancer. The main influencing factors of colorectal cancer cognition were education level and occupation. Patients who work in institutions and enterprises and with higher education level had better cognition. Conclusion Patients with middle- and advanced-stage colorectal cancer in Inner Mongolia have poor knowledge and awareness of risk factors and screening of colorectal cancer before diagnosis. Education level and occupation are factors influencing colorectal cancer cognition, therefore, people with low knowledge rate of colorectal cancer and low education level as well as unemployed laid-off people should be given priority intervention.

Age-dependent loss of skeletal muscle mass and function is a feature of sarcopenia, and increases the risk of many aging-related metabolic diseases. Here, we report phenotypic and single-nucleus transcriptomic analyses of non-human primate skeletal muscle aging. A higher transcriptional fluctuation was observed in myonuclei relative to other interstitial cell types, indicating a higher susceptibility of skeletal muscle fiber to aging. We found a downregulation of FOXO3 in aged primate skeletal muscle, and identified FOXO3 as a hub transcription factor maintaining skeletal muscle homeostasis. Through the establishment of a complementary experimental pipeline based on a human pluripotent stem cell-derived myotube model, we revealed that silence of FOXO3 accelerates human myotube senescence, whereas genetic activation of endogenous FOXO3 alleviates human myotube aging. Altogether, based on a combination of monkey skeletal muscle and human myotube aging research models, we unraveled the pivotal role of the FOXO3 in safeguarding primate skeletal muscle from aging, providing a comprehensive resource for the development of clinical diagnosis and targeted therapeutic interventions against human skeletal muscle aging and the onset of sarcopenia along with aging-related disorders.

Objective:To explore the association of different obesity measurement indexes on serum C-reactive protein (CRP) in Chinese adult women.Methods:The data were obtained from baseline and follow-up surveys of the urban Breast Cancer Screening Program in Shuangliu District, Chengdu. A total of 441 adult women were included in the study. A questionnaire survey, physical examination, and laboratory testing were conducted on the subjects. Multivariate logistic regression model, two-level mixed effects logistic regression model, and restricted cubic spline method were used to investigate the linear and nonlinear correlation between different obesity measurement indexes and serum CRP in adult women.Results:For every 1 unit increase in BMI, waist circumference (WC), and adiposity, the risk of elevated serum CRP or exacerbation of chronic low-grade inflammation in adult women increased by 16.5%, 5.0%, and 11.1% ( P<0.05), respectively. Both BMI and adiposity were nonlinear correlated with serum CRP. Using BMI=24.0 kg/m 2 as the reference point, serum CRP level increased with the increase of BMI when BMI >24.0 kg/m 2. Using adiposity=30% as the reference point, serum CRP level increased with the increase of adiposity when adiposity >30%. Conclusions:Overall, obesity reflected by BMI had the strongest association with serum CRP in adult women, followed by body fat content reflected by adiposity, and central obesity reflected by WC had the weakest association with CRP. Adult women with BMI >24.0 kg/m 2 or adiposity >30% are at high risk for obesity-related inflammatory manifestations.

Objective:To investigate the correlation between serum anti-phospholipase A2 receptor antibody (SAb) combined with glomerular complement C3 (GC3) deposition and clinicopathologic features and prognosis in patients with idiopathic membranous nephropathy (IMN).Methods:It was a retrospective cohort study. The patients diagnosed with IMN in Affiliated Hospital of Qingdao University from July 1, 2019 to April 30, 2022 were enrolled, and the clinical and pathological data were collected and analyzed. The patients were divided into negative SAb and negative GC3 (SAb -/GC3 -) group, negative SAb and positive GC3 (SAb -/GC3 +) group, positive SAb and negative GC3 (SAb +/GC3 -) group and positive SAb and positive GC3 (SAb +/GC3 +) group according to the status of SAb titer and GC3 deposition. Clinical and pathological characteristics among the groups were compared. Kaplan-Meier survival curve was used to compare the cumulative renal remission rates of different groups. Cox regression analysis model was used to analyze the related factors of renal remission. Results:A total of 143 IMN patients aged (53.35±12.34) years old were included in the study, including 94 males (65.7%). There were 17 patients (11.9%) in the SAb -/GC3 - group, 30 patients (21.0%) in the SAb -/GC3 + group, 19 patients (13.3%) in the SAb +/GC3 - group, and 77 patients (53.8%) in the SAb +/GC3 + group. Compared with SAb -/GC3 - group, the level of serum albumin was lower in the SAb +/GC3 + group, and the level of 24 h urine protein, SAb titer, and the proportions of glomerular anti-phospholipase A2 receptor antigen and renal tubule atrophy were higher in the SAb +/GC3 + group (all P<0.05). After 26.0 (19.0, 36.0) months of follow-up, a total of 96 patients (67.1%) attained remission. The proportion of patients receiving immunosuppressive therapy in the SAb +/GC3 + group was higher than that in the SAb -/GC3 - group [93.5% (72/77) vs. 70.6% (12/17), fisher value=8.974, P=0.016] and the proportion of renal remission rate in the SAb +/GC3 + group was lower than that in the SAb -/GC3 - group [49.4% (38/77) vs. 100% (17/17), χ2=25.438, P<0.001]. Kaplan-Meier survival curve result showed that the cumulative renal remission rate in the SAb +/GC3 + group was significantly lower than that in the SAb -/GC3 - group (Log-rank χ2=31.538, P<0.01). Multivariate Cox regression analysis result showed that 24 h urine protein level ( HR=0.891, 95% CI 0.803-0.988, P=0.029), SAb titer ( HR=0.996, 95% CI 0.992-1.000, P=0.042) and SAb +/GC3 + (with SAb -/GC3 - group as reference, HR=0.414, 95% CI 0.204-0.827, P=0.013) were independent related factors for renal remission in patients with IMN. Conclusions:IMN patients with positive SAb and GC3 deposition have more severe clinical and pathological changes, lower renal cumulative remission rates, and are more likely to have poor prognosis. The combined assessment of SAb and GC3 deposition may be helpful for evaluating prognosis and guiding treatment in IMN patients.
