Applying Chinese medicine (CM) is an important strategy for malignant tumor treatment in China. One of the significant characteristics of CM is to treat diseases based on syndrome differentiation. For Western medicine, it is of important clinical significance to formulate guidelines for the diagnosis and treatment of cancer patients based on the characteristics of disease differentiation. In Chinese clinical practice, the combination of disease differentiation and syndrome differentiation is an important feature for cancer treatment in the past. Currently, molecular profiling and genomic analysis-based precision medicine optimizes the anticancer drug design and holds the greatest success in treating cancer patients. Therefore, we want to know which populations of cancer patients can benefit more from CM treatment if the theory of precision medicine is applied to CM clinical practice. So, we developed a novel diagnostic and therapeutic strategy "disease-syndrome differentiation-genomic profiling-prescriptions" for cancer patients by CM syndrome differentiation and precision medicine. As a result, this strategy has greatly enhanced the anti-tumor efficacy of CM and improved clinical outcomes for cancer patients with some gene mutations. Our idea will hopefully establish a novel approach for the inheritance and innovation of CM.

Objective To investigate the effect of cysteine protease inhibitor derived from S chistosoma japonicum(SjCys-tatin)on dextran sodium sulfate(DSS)-induced acute ulcerative colitis in mice.Methods Eighteen C57BL/6 mice were ran-domly divided into three groups:a control group treated with PBS(Group A),a DSS-induced-colitis group treated with PBS(Group B),and a DSS-induced-colitis group treated with SjCystatin(Group C).Colitis was induced in mice by giving 3％DSS orally for 7 days.During this period,the mice were daily injected with 10μg of SjCystatin or PBS only as a control intraperitone-ally.The mice were monitored daily for their clinical manifestations and given scores based on disease activity index(DAI).The severity of colonic inflammation was monitored by the macroscopic score and pathological change.The cytokine profile including TNF-α,IL-4,IL-6 and IL-10 in the supernatants of colon homogenate was detected by ELISA.Results Compared with Group A(0.50 ± 0.28),the DAI score increased significantly in Group B(9.30 ± 1.30)(F=86.86,P<0.01),with remarkable path-ological damages seen in colon tissues.and the levels of TNF-α and IL-6 were(321.33±67.01)and(403.58 ±180.51)pg/mL.The DAI score significantly reduced in Group C(6.67±1.57)as compared to Group B(F=86.86,P<0.01),with improve-ments in the macroscopic and microscopic pathology in mouse colon specimens.As compared to Group B,the levels of TNF-α [(188.14 ± 40.14)pg/mL] and IL-6 [(209.71 ± 48.47)pg/mL] significantly decreased(F=17.46 and 9.89,both P<0.01).Con-clusion SjCystatin has a significantly inhibitory effect for alleviating DSS-induced acute ulcerative colitis in C57BL/6 mice.

Background: Esophageal cancer is associated with substantial disease burden in China, and data on the economic burden are fundamental for setting priorities in cancer interventions. The medical expenditure for the diagnosis and treatment of esophageal cancer in China has not been fully quantified. This study aimed to examine the medical expenditure of Chinese patients with esophageal cancer and the associated trends. Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 37 hospitals in 13 provinces/municipalities across China as a part of the Cancer Screening Program of Urban China. For each esophageal cancer patient diagnosed between 2002 and 2011, clinical information and expense data were extracted by using structured questionnaires. All expense data were reported in Chinese Yuan (CNY; 1 CNY= 0.155 USD) based on the 2011 value and inflated using the year-specific health care consumer price index for China. Results: A total of 14,967 esophageal cancer patients were included in the analysis. It was estimated that the overall average expenditure per patient was 38,666 CNY, and an average annual increase of 6.27％ was observed from 2002 (25,111 CNY) to 2011 (46,124 CNY). The average expenditures were 34,460 CNY for stage Ⅰ, 39,302 CNY for stage Ⅱ, 40,353 CNY for stage Ⅲ, and 37,432 CNY for stage IV diseases (P < 0.01). The expenditure also differed by the therapy type, which was 38,492 CNY for surgery, 27,933 CNY for radiotherapy, and 27,805 CNY for chemotherapy (P < 0.05). Drugs contributed to 45.02％ of the overall expenditure. Conclusions: These conservative estimates suggested that medical expenditures for esophageal cancer in China substantially increased in the last 10 years, treatment for early-stage esophageal cancer costs less than that for advanced cases, and spending on drugs continued to account for a considerable proportion of the overall expenditure.

OBJECTIVETo explore the effects of TBLR1-RARα on the differentiation induction of leukemia cell line K562 cells into erythroid lineage and to investigate its related mechanisms.

METHODSTet-Off inducible system was used to construct the conditional expression vector of TBLR1-RARα fusion gene by cloning the TBLR1-RARα fragment into lentivirus vector pLVX-Tight-Puro, the expression of TBLR1-RARα fusion gene was induced by doxycycline (Dox). Then, K562 cells were transfected with lentivirus pLVX-Tight-Puro-TBLR1-RARα-flag, and the expression of fusion proteins was verified by Western blot. After treatment of K562 with all-trans retinoid acid (ATRA), real time RT-PCR was performed to test the expression of erythroid differentiation-related CD71 and α, ε, γ-globins gene. Flow cytometry was used also to analyze the expression of erythroid differentiation markers CD71 and CD235a. Benzidine staining was used to detect the production of hemoglobin in K562 cells.

RESULTSqRT-RCR showed that ATRA could increase the expression level of CD71 and α, ε, γ-globin genes when TBLR1-RARα was expressed. After treatment of ATRA, the proportion of CD71(+) cells detected by the flow cytometry also increased. Benzidine staining showed that ATRA could induce hemoglobin production in K562 cells with TBLR1-RARα fusion gene expression.

CONCLUSIONThe expression of TBLR1-RARα fusion gene contribute to ATRA-inducing differentiation of K562 cells into erythroid lineage.

Objeetive To evaluate the impact of viable myocardium assessed by 99Tcm-MIBI SPECT and 18F-flourodeoxyglucose(FDG) PET imaging in patients with left ventricular aneurysm(LNA) underwent revascularization (RVS).Methods Forty-six consecutive patients with LVA (mean LVEF 36%±7%),underwent 99Tcm-sestamibi SPECT and 18F-FDG PET examinations and received RVS therap,were followed-up for a mean period of 80±27 months.Viable myocardium in anenrysm was defined as perfusionmetabolism mismatch score (MMS) ≥2.0.Patients were divided into four groups by aneurysm viability and aneurysmectomy.Group A1 (n=8):viability-;Group A2 (n=15):viability-,aneurysmectomy;Group B1 (n=10):viability+;and Group B2 (n=13):viability+,aneurysmectomy.Results The cardiac event rates during follow up were similar among groups [A1(25%,2/8),B1(40%,6/15),A2(20%,2/10) and B2(31%,4/13:P＞0.05].After revascularization,LVEF was impmved (＞10%) in groups A2,B1 and B2(P＜0.05).Multivariate logistic regression analysis showed that LV-MMS(OR=2.34,95% CI 1.08-5.06,P＜0.05).distal vessel disease(OR=0.008,95% CI 0.001-0.560,P＜0.05) and nonaneurysm perfusion score (OR=0.24.95% CI 0.07-0.85.P＜0.05) were significantly associated with the improvement of LVEF after revascularization.Conclusions Long term cardiac events rate post revascularization was not affected by viable myocardium or aneurysmectomy in LVA patients.Viable myocardium in LVA patients was associated with better LVEF improvement after revascularization.

To determine cancer pathway activities in nine types of primary tumors and NCI60 cell lines, we applied an in silico approach by examining gene signatures reflective of consequent pathway activation using gene expression data. Supervised learning approaches predicted that the Ras pathway is active in ～70% of lung adenocarcinomas but inactive in most squamous cell carcinomas, pulmonary carcinoids, and small cell lung carcinomas. In contrast, the TGF-β, TNF-α, Src, Myc, E2F3, and β-catenin pathways are inactive in lung adenocarcinomas. We predicted an active Ras, Myc, Src, and/or E2F3 pathway in significant percentages of breast cancer, colorectal carcinoma, and gliomas. Our results also suggest that Ras may be the most prevailing oncogenic pathway. Additionally, many NCI60 cell lines exhibited a gene signature indicative of an active Ras, Myc, and/or Src, but not E2F3, β-catenin, TNF-α, or TGF-β pathway. To our knowledge, this is the first comprehensive survey of cancer pathway activities in nine major tumor types and the most widely used NCI60 cell lines. The "gene expression pathway signatures" we have defined could facilitate the understanding of molecular mechanisms in cancer development and provide guidance to the selection of appropriate cell lines for cancer research and pharmaceutical compound screening.
