The traditional conotation of combination of disease and syndrome means the combination of disease differentiation in traditional Chinese medicine (TCM) diseases and TCM syndrome differentiation,which was derived from the Yellow Emperor's Inner Classic.And the Treatise on Cold Damage and Miscellaneous Diseases describes the clinical application of this theory.Under the background of integrative medicine,the modern conotation of combination of disease and syndrome means TCM syndrome differentiation and treatment based on modern medicine disease differentiation,which is commonly used in the current clinical practice.The disease and syndrome combination diagnosis mode based on syndrome,etiology,pathology and pharmacology can understand the disease from a multiple and comprehensive level,in order to realize the combination and complementation of advantages from both medicines.In addition,formula-syndrome relation means the relationship between the formula and its relevant indications.In general,indications often involve syndromes,symptoms,diseases and body constitutions.And the application of formula in the Treatise on Cold Damage and Miscellaneous Diseases is the representative of this theory.Hence,the application of associated classical formula gives example to the clinical formula-syndrome relation application in modem times.

Objective To investigate the effect of interleukin 6 (IL-6) on the growth and proliferation of human pancreatic cancer cell line Capan-2 and the signal transduction pathway. Methods MTr method was used to detect the effect of IL-6 of different concentrations on the growth and proliferation of Capan - 2 cells; cell apoptosis was detected by flow cytometry; the intracellular localization of phosphorylated STAT3 (P-STAT3) was determined by immunocytochemistry and western blot were used to detect P-STAT3, bcl-xl and Cyclin D1 in Capan-2 cells stimulated by IL-6. Results IL-6 (100 ng/ml) could remarkably promote the growth of Capan-2 cells from 1 to 4. 965 ± 0. 18 (P < 0. 05) ; the percentage of apoptosis decreased significantly from (3.21 ±0.23)% to (1.98 ±0.67)% (P <0.05) ; the expressions of P-STAT3, bcl-xl, Cyelin D1 increased significantly (P < 0.05), and the expressions of bcl-xl was positively correlated with that of P-STAT3 (r =0.985, P =0.015) ; the expressions of Cyclin DI was also positively correlated with that of P-STAT3(r=0.914,P=0.036),Conclusions IL-6 activate JAK/STAT signal transduction pathway,which played an important role in the growth and proliferation of Capan-2 cells in the presence of IL-6.

Objective To study the genotype of the thyroid hormone receptor ? (THRB) gene in a patient with thyroid hormone resistance syndrome. Methods The peripheral blood samples of the patient and his parents were collected, then DNA was isolated. PCR and direct sequencing techniques were performed to determine if there were mutations in their THRB gene. Results No mutation was found in exon 1-9. There was a point mutation in exon 10 of THRB which is a T to C transition in nucleotide 1658 resulting in the replacement of the normal Val (GTG) with an Ala (GCG) (V458A). The mutation was located in exon 10 of THRB gene and was a heterozygote. No mutation was found in THRB gene of his parents.Conclusion The gene diagnosis confirms that the patient has a mutation V458A located in the ligand binding area of THRB.

Objective To investigate the effects of chemokine CCL18 on the proliferation and invasion of a human melanoma cell line A375. Methods Human peripheral blood monocytes were isolated from healthy volunteers, cultured in vitro and divided into two groups to be induced by IL-4 for 48 hours or remain untreated. A375 cells were classified into 3 groups to be cultured with IL-4-induced monocytes, untreated monocytes or CCL18 of 200 g/L for various durations. A375 cells receiving no treatment served as the control.MTT assay was performed to detect the proliferation of A375 cells, chemotaxis test and Matrigel-transwell assay to evaluate the chemotaxis and invasion ability of A375 cells, and chicken chorioalllantoic memebrane (CAM)was used to detect the effect of CCL18 on tumor angiogenesis. Results The proliferation of A375 cells was statistically accelerated by IL-4-induced monocytes and untreated monocytes, but unaffected by CCL18.Matrigel-transwell assay revealed that IL-4-induced monocytes and CCL18 promoted the chemotaxis and invasion ability of A375 cells (all P＜0.05). Tumor angiogenesis was also increased by IL-4-induced monocytes and CCL18 (both P ＜ 0.05). Conclusion The chemokine CCL18 can promote the invasion ability of A375 cells and tumor angiogenesis.

Objective: In order to investigate the effects of activating and blocking Stat3 signaling pathway on invasion ability of human pancreatic cancer cells and explore its action mechanism.Methods:Human pancreatic cancer Capan-2 cells were treated with IL-6. SW1990 human pancreatic cancer cells were treated with AG490. Cell proliferation was measured by MTT assay. Western blotting and immunocytochemistry were performed to detect expression of phosphorylated Stat3 (p-Stat3) protein. Real-time fluorogentic quantitative PCR (RFQ-PCR) and Western blotting were used to detect the mRNA and protein expression of VEGF and MMP-2 mRNA, respectively. The invasion abilities of SW1990 and Capan-2 cells were determined by cell invasion assay in vitro. Results:IL-6 stimulated the proliferation of Capan-2 cells (P<0.05), elevated the expression of p-Stat3, increased the mRNA and protein expressions of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 2 (MMP-2) (P<0.05), and enhanced the invasion ability of Capan-2 cells. AG490 inhibited the proliferation of SW1990 cells (P<0.05), down-regulated the expression of p-Stat3, markedly decreased the mRNA and protein expression of VEGF and MMP-2 (P<0.05), and weakened the invasion ability of SW1990 cells. Conclusion:Stat 3 signaling pathway plays an important role in the invasion and metastasis of pancreatic cancer. Stat 3 signaling transduction pathway may provide a novel therapeutic target for the treatment of pancreatic cancer.
