This article was aimed to expound current complexity and diversity about Chinese medicine dose-ef-fect relationship . It demonstrated that the study on Chinese medicine dose-effect relationship should be based on clinical effect as its foundation , and be guided by the traditional Chinese medicine ( TCM ) theories . Differ-ent modern science and technology means and methods should be applied for the multi-perspective , multi-lev-el and multidisciplinary systematic study of the Chinese medicine dose-effect relationship .

Objective To investigate the incidence and relevant factors of upper gastrointestinal bleeding(UGB)in patients with coronary heart disease(CHD)undergoing dual antiplatelet therapy(DAT)with aspirin plus clopidogrel.Methods A total of 391 CHD patients treated with aspirin plus clopidogrel (DAT group)and 502 control CHD patients receiving single antiplatelet therapy(SAT)with aspirin or clopidogrel(SAT group)were enrolled.The incidence and relevant factors associated with UGB were retrospectively analyzed in both groups of patients.Data were analyzed with Chi-square test and logistic regression by using SAS software version 9.0.Results The incidence of UGB in DAT group was significantly higher compared with SAT group(7.1% vs.3.4%,P < 0.01).The factors,including DAT,age over 65 years,medication duration over 3 months and previous digestive diseases increased the risk of UGB in CHD patients(P < 0.05),while the use of PPIs(proton-pump inhibitors)or gastric mucosal protectives lowered the risk of UGB(OR:0.415,95% CI 0.226 ~ 0.762,P =0.0035).Conclusions DAT can significantly increase the risk of UGB.UGB can be increased in elderly CHD patients and those with long-term medication and previous digestive diseases.Utility of PPIs or gastric mucosal protectives can effectively lower the incidence of UGB.

Systems biology, which includes genomics, proteomics, transcriptomics and metabolomics, is an integration of system theory and biology. It studies the life phenomena with thinking method of systems theory. And it provides an important methodological basis and technical conditions for recognizing syndrome of traditional Chinese medicine (TCM) and mechanism of therapeutic effect from multiple disciplines and perspectives. Systems biology is similar to the core idea of TCM system and holism concept. Therefore, systems biology can be used as a platform and pivot of non-alcoholic fatty liver disease (NAFLD) in modern TCM study. Systems biology will accelerate the modernization research of TCM in the prevention and treatment of NAFLD. It will also provide new ideas and methods for TCM study on NAFLD.

Objective To study the anti-tumor effects of mixed cultured B16 melanoma cells supernatant.Methods The supernatant from purely cultured B16 melanoma cells or mixedly cultured B16 melanoma cells with lymphocytes and macrophages at indicated time points were collected,respectively.The chemotaxis of the two different cell supernatants was determined by Boyden room method.The activation effects towards lymphocytes of the two different supernatants were determined by CCK-8 method.Results When the cells were mixed cultured for 0.5,1,2,4,8 and 12 h,the numbers of lymphocytes to travel from the upper well to the bottom well were (1.00±0.82) × 104,(7.00±1.63) × 104,(9.50±0.58) × 104,(11.25±2.36) ×104,(17.25±1.71) × 104 and (21.50±1.29) × 104,respectively.When the cells were purely cultured for 0.5,1,2,4,8 and 12 h,the numbers of lymphocytes to travel from the upper well to the bottom well were (0.00±0.00) ×104,(0.25±0.50) × 104,(1.75±0.96) × 104,(5.25±0.96) × 104,(5.75±1.26) × 104 and (10.75±3.20) × 104,respectively.The mixed cultured group showed higher chemotaxis effects towards lymphocytes in comparison with the purely cuhured one at the same points except for 0.5 h (P < 0.05).The mixed cultured group showed higher activation effects towards lymphocytes in comparison with the purely cultured at the same points except for 0.5 and 1 h (P < 0.05).Each group showed higher chemotaxis and activation effects towards lymphocytes when they were cultured for 12 h than the other time points (P <0.05).Conclusion The supernatant from mixed cultured cells shows much higher chemotaxis and activation effects towards lymphocytes to kill tumor cells.

Objective Evaluation of Chinese-thyroid imaging reporting and data system(C-TIRADS)combined with contrast-enhanced ultrasound(CEUS)for the assessment of category 4 nodules in the setting of Hashimoto's thyroiditis.Methods Retrospective analysis of 120 C-TIRADS category 4 thyroid nodules from 79 patients with confirmed Hashimoto's thyroiditis who attended the Yiyang Central Hospital from June to December 2022.Thyroid nodules exhibiting one or more benign or malignant features that were suspicious on CEUS were treated as downgraded or upgraded one level.Using the final surgical pathology results as the gold standard,working characteristic(ROC)curves of subjects based on C-TIRADS grading before and after CEUS adjustment were plotted to compare diagnostic efficacy.Results The sensitivity,specificity,and accuracy of the CEUS-adjusted C-TIRADS were 93.0%,87.8%and 90.8%,respectively(P<0.05).The area under the ROC curve was 0.811 and 0.904,respectively(P<0.05).Conclusion C-TIRADS combined with CEUS has better diagnostic efficacy in evaluating category 4 nodules in Hashimoto's thyroiditis.

Objective To investigate the feasibility of the scheme of target volume delineation with extended involved?field intensity?modulated radiotherapy (IMRT) for patients with early?stage nasal NK/ T?cell lymphoma (NC?NKTL). Methods Twenty?one patients with stage IE?IIE NC?NKTL were treated with short?course chemotherapy combined with radiotherapy from 2011 to 2013. The majority of patients received the GELOX regimen. All patients received extended involved?field IMRT with a dose of 54?? 6 Gy in 26 fractions for gross tumor volume, 50?? 7 Gy in 26 fractions for high?risk clinical target volume (CTV), and 45?? 5 Gy in 26 fractions for low?risk CTV. The dose distribution, short?term treatment outcomes, and adverse reactions were analyzed. Results The 2?year sample size was 12. The 2?year follow?up rate was 100%. The 2?year local control rate ( LRC) was 100%. The 2?year overall and progression?free survival rates were 90?? 5% and 90?? 5%, respectively. The median coverage rates of planning target volumes with 90% of the prescribed doses of 54?? 6 Gy, 50?? 7 Gy, and 45?? 5 Gy were 99?? 8%, 99?? 6%, and 99?? 7%, respectively. No grade 3 or 4 adverse reactions were observed in patients. Conclusions The scheme of target volume delineation and dose configuration in our study not only achieves excellent target volume coverage, but also reduces adverse reactions in patients, which achieves a 2?year LRC ideal for patients with early?stage NC?NKTL.
