Objective To assess the diagnostic value of ultrasonographic elastography for identifying suspected malignant thyroid nodules. Methods Fifty-one patients with small single solid thyroid nodule underwent two-dimensional and color power Doppler ultrasonography. The size, shape, boundary, internal echo and halo, calcification of thyroid nodule were observed with two-dimensional ultrasound. Then color Doppler ultrasonography was used to detect blood signal and distribution in the nodules. Longitudinal scanning of elastography was performed, and the findings on elastography were classified into Ⅰ-Ⅴ grades. The ultrasonographic results were compared with pathologic findings. Results Six patients were found with grade Ⅰ and Ⅱ benign lesions;9 with grade Ⅲ ( 6 benign and 3 malignant), 36 with Ⅳ and Ⅴ (2 benign and 34 malignant) lesions on ultrasonographic elastography. Taking the elasticity grade Ⅳ or Ⅴ as malignant standard, the diagnostic sensitivity was 91.89%, specificity was 85.71%, accuracy was 90.20%, while the positive and negative predictive value was 94.44% and 80.00%, respectively. Conclusion Real-time ultrasound elastography is a promising imaging technique that can assist in the differential diagnosis of malignant thyroid small single solid nodule.

Objective To investigate the relationship between thyroid nodules with calcification and thyroid carcinoma and its significance in the screening of thyroid carcinoma in high risk group.Methods The clinical data of 1771 patient undergoing surgery for thyroid nodules from March, 2006 to March, 2009 in Huashan Hospital, Fudan University were retrospectively analyzed. Results Among 1771 patients, 500 were finally identified as having malignant tumors. Incidence of calcification in thyroid carcinoma was 68. 4%, and that in benign thyroid nodules was 27.0% ( χ2 = 259. 5, P ＜ 0. 05 ).

The incidence of carcinoma in patients of single thyroid nodule was 31.7% and that in those with multiple nodules was 26. 4% (χ2 =4. 766,P ＜ 0. 05). Metastasis was pathologically diagnosed in 26. 8% of lymph nodes found by preoperative ultrasonography. Conclusions The specificity of thyroid nodule calcification, especially microcalcification is high for the diagnosis of thyroid carcinoma. High-risk index for carcinoma includes thyroid nodules with microcalcification, ＜ 45 years old and single thyroid nodule.

Objective Observing the effect of Shuganyishen formula on hormone-dependant metastatic breast cancer and the mechanisms of anti-resistance and endocrine therapy. Methods 226 ITT cases were divided into two cohorts by treatment. 126 cases were treated with the combination of Shuganyishen formula and standard western medicine including endocrine therapy, and 100 cases were treated with western medicine alone. The end points were time to progress (TTP) and overall survival and quality of life (QOF). The effect of Shuganyishen formula on growth of TAM-resistance cell line in vitro was observed. Results There were statistical significances of median TTP between combination and western medicine in Luminal A (ER+ /PR+, HER2-) as well as Luminal B (ER+/PR+, HER2+), but no significances of OS; The extent and incidence of hot flush, sweat and syndromes related to bone were decreased significantly in combination treated group. Shuganyishen formula could reverse resistance to TAM. Conclusion Patients with LuminalA and LuminalB metastatic breast cancer benefit from Shuganyishen formula, which maybe related with its reverse resistance to endocrine therapy.

BACKGROUNDIt has been known that there are declines of dendritic cell (DC) count and its function in the peripheral blood of patients with non-small cell lung cancer (NSCLC), which are remarkably related to the proceeding and prognosis of NSCIC. The aim of this study is to investigate the relationship and clinical significance between the DC subsets (CD11c+DC and CD123+DC) and immunology state of patients with advanced NSCLC.

METHODSFlow cytometry was used to detect DC subsets, T cell subsets, NK cell percentage in the peripheral blood of 40 patients with advanced NSCLC and 10 healthy controls.

RESULTSThe expression of CD11c+DC (0.38%±0.18%) in the peripheral blood of advanced NSCLC patients, was decreased significantly compared with that of normal controls (0.66%±0.24%) (P < 0.01). The expression of CD123+DC in the peripheral blood of advanced NSCLC patients was (0.28±0.17)%, with no significant difference compared with that of normal controls (0.27%±0.11%) (P > 0.05). The percentage of CD3+ T cell and CD4+/CD8+ of patients with advanced NSCLC were significantly lower than those of normal controls (P < 0.01 and P < 0.05), and the percentage of CD8+ and NK cell of patients were higher than those of normal controls (P < 0.05). The correlation analysis showed that CD123+DC percentage was positively correlated to CD3+T cell percentage (P < 0.05) and negatively correlated to NK cell percentage (P < 0.01). The expression of DC subsets correlated with KPS and chemotherapy history of patients (P < 0.01).

CONCLUSIONSThe advanced NSCLC may induce significant decreasing expression of CD11c+DC and may induce significant decrease of immunology state. There are close relationship among the expression of DC subsets and the immunology state of patients as well as the clinical biological behaviors of patients with advanced NSCLC.

Cervical cancer is a gynecological malignant tumor with a high incidence in the world. With the insidious onset and lack of obvious symptoms and signs in the early stage， 13% of cervical cancer patients are diagnosed in the advanced stage of the disease， and the 5-year survival rate of metastatic cervical cancer is only 16.5%. So far， surgery and radiotherapy/chemotherapy are still the basic means for the treatment of cervical cancer. However， with the emergence of toxicity， drug resistance， and other side effects， there are still some limitations in the clinical application of these therapies. In recent years， natural compounds represented by polysaccharides have been found to have a significant anti-cervical cancer effect， which has attracted extensive attention from researchers in China and abroad. Widely distributed in the roots， stems， leaves， flowers， and fruits of higher plants， plant-based polysaccharides are important components of natural polysaccharides， as well as multimers with a complex structure and biological response regulators， which have been widely studied in the fields of cancer， cardiovascular， endocrine， and other diseases. This study reviewed the research on the anti-cervical cancer effect and mechanism of natural plant-derived polysaccharides by consulting the literature in the past 20 years to bring breakthroughs in the research and development of anti-cervical cancer new drugs. Through the literature review， the results indicated that natural plant-derived polysaccharides could exert anti-tumor effects by inhibiting cell proliferation， promoting apoptosis， inhibiting invasion and migration， promoting autophagy， arresting cell cycle of cervical cancer cells， regulating epithelial-mesenchymal transition （EMT）， resisting oxidative stress， inhibiting tumor angiogenesis， improving immunomodulatory activity， and regulating signaling pathways. It should be noted that in the current research on natural plant-derived polysaccharides against cervical cancer， the bioavailability of some natural polysaccharides is low and a considerable proportion of the research is limited to the in vitro experiment. Therefore， it is urgent to carry out more clinical experimental studies on the anti-cervical cancer of natural plant-based polysaccharides to obtain a more reliable theoretical and practical basis.

Animal experiments play an important role in the process of biomedical research, and is a necessary way to transform basic medicine into clinical medicine. The standardization of animal experimental studies and reports determines the reliability and reproducibility of research results, and is also the key to transforming the results of animal experiments into clinical trials. In view of how to design and implement animal experiments, write animal experiment reports, and publish relevant academic papers in a more standardized way, LACM (Laboratory Animal and Comparative Medicine) has launched a new column of comparative medical research and reporting standards from 2023, focusing on the introduction and interpretation of international general norms related to laboratory animal and comparative medicine, such as ARRIVE 2.0 guidelines (Animal Research: Reporting of In Vivo Experiments). This article focuses on the development and application, basic content and priority of ARRIVE 2.0, as well as the scheme of implementing ARRIVE 2.0 guidelines in international biomedical journals, and explains the current situation and future plans of LACM following ARRIVE 2.0 guidelines. The research and report of animal experimental medicine following the ARRIVE 2.0 guidelines and other international norms is one of the important driving forces to promote the high-quality development of experimental animal science and biomedicine in China, and also a powerful means to implement the 3R principle and improve the welfare of laboratory animals. Through this article, we hope the majority of scientific researchers and editors will attach great importance and actively implement these international standards.
