0.05).Conclusion There is no significant difference of short-term effect between the two groups in treating advanced NSCLC,and the method has mild digestive reactions and nephrotoxicity.

ObjectiveTo evaluate the short-term effect and side effects of ICE regimen treating the patients with relapsed and refractory non-Hodgkin's lymphoma(NHL). MethodsTwenty-five patients with relapsed and refractory NHL were treated with ICE regimen. Treatment was repeated every 3 weeks. ResultsThe total effective rate was 76.0％ for 25 patients,The response rate(PR) was 60.0％. The main side effects were marrow suppression including of leucopenia and thrombocytopenia,no patients dead for toxic reactions of chemotherapy. ConclusionICE regimen was a safe and effective salvage regimen for the patients with relapsed and refractory NHL.

OBJECTIVE: To investigate the influence of occupational and environmental factors on the pregnancy for Down's syndrome. METHODS: By systematic sampling method,97 pregnant women who had been diagnosed as Down's syndrome by Giemsa staining on fetal chromosomes in chorionic villus sampling,amniocentesis,or umbilical cord blood sampling were selected as the case group,while 373 non-Down's syndrome pregnant women after same examinations during the same period in the same hospital were selected as the control group. The history of exposure before pregnancy to occupational and environmental factors was analyzed. RESULTS: The pregnant women aged over 35 years had higher risk of Down's syndrome than those aged under 35 years( P < 0. 01). The pregnant women with occupational exposure to organic solvents containing benzene had higher risk of Down's syndrome than those without occupational exposure history to hazardous substances( P < 0. 01). The pregnant women using estrogenic drugs before pregnancy or during early pregnancy had higher risk of Down's syndrome than those without drug use( P < 0. 05). The pregnant women living in newly-decorated houses or using the new furniture had higher risk of Down's syndrome than those without new decoration( P < 0. 01). The pregnant women with pre-pregnancy intake of folic acid had lower risk of Down's syndrome than those without any intake of folic acid supplement( P < 0. 05). CONCLUSION: The age,occupational exposure to benzene solvents and taking estrogenic drugs were the major leading factors of development of Down's syndrome.

Objective:To analyze the risk factors for central lymph node metastasis (CLNM) in patients with papillary thyroid cancer (PTC) aged 55 years and above, and to construct a predictive model with columnar graph.Methods:This retrospective study included 406 PTC patients aged 55 and above, treated at the First Affiliated Hospital of Zhengzhou University from Nov. 2019 to Feb. 2022. Data on demographic characteristics, disease features, and laboratory test results were collected. Univariate and multivariate logistic regression analyses were used to identify risk factors for CLNM and develop a clinical prediction model and nomogram.Results:The study involved 406 patients, divided into a modeling group (285 patients) and a validation group (121 patients). The predictive model identified independent risk factors for CLNM. In the modeling group, the model demonstrated a ROC AUC of 0.769, with 82.6% sensitivity, 63.0% specificity, and 67.7% accuracy. The validation group showed 66.7% sensitivity, 74.5% specificity, and 72.7% accuracy, with an AUC of 0.760. Hosmer-Lemeshow tests indicated good fit in both groups. Decision curve analysis confirmed the model's clinical decision-making value, showing better performance than traditional strategies and good generalizability and reliability.Conclusions:Sex, maximum tumor diameter, bilateral involvement of thyroid lobes, clinically evident cervical lymph nodes, and local invasion are independent predictive factors for CLNM in patients over 55 with papillary thyroid carcinoma (PTC). A clinical risk stratification nomogram model based on these risk factors demonstrates good predictive performance.

As the elderly population continues to rise, the issue of disease diagnosis and treatment in the elderly population is becoming a hot topic of concern. Differentiated thyroid cancer is the most common endocrine malignancy in the world, and patients with differentiated thyroid cancer in the elderly have a worse clinical prognosis and higher risk of recurrence and metastasis. Moreover, due to the special characteristics and complexity of the elderly population, patients with differentiated thyroid cancer in the advanced age group have special features in terms of morbidity, preoperative diagnosis, treatment options, and postoperative management compared with other populations. This article reviews the current status of diagnosis and treatment of differentiated thyroid cancer in the elderly, taking into account the findings and opinions of domestic and international studies.

Basophils, which are considered as redundant relatives of mast cells and the rarest granulocytes in peripheral circulation, have been neglected by researchers in the past decades. Previous studies have revealed their vital roles in allergic diseases and parasitic infections. Intriguingly, recent studies even reported that basophils might be associated with cancer development, as activated basophils synthesize and release a variety of cytokines and chemokines in response to cancers. However, it is still subject to debate whether basophils function as tumor-protecting or tumor-promoting components; the answer may depend on the tumor biology and the microenvironment. Herein, we reviewed the role of basophils in cancers, and highlighted some potential and promising therapeutic strategies.

Accumulative evidences have underpinned the nature candidates from Chinese medicine (CM), particularly CM served as blood activating and stasis resolving (BASR, Huoxue Huayu in Chinese) by targeting tumor-associated angiogenesis. However, recent experiment research on the therapeutic angiogenesis by BASR-CM attracts wide attention and discussion. This opinion review focused on the underlying link between two indications and anticipated that (1) BASR-CM might emphasize on a balanced multi-cytokines network interaction; (2) BASR-CM might address on the nature of diseases prior to differently affecting physiological and pathological angiogenesis; (3) BASR-CM might mainly act on perivascular cells, either promotes arteriogenesis by increasing arteriogenic factors in ischemic diseases, or simultaneously keep a quiescent vasculature to impede angiogenesis in tumor context.
