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 .

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: To investigate the effects of Yiguanjian Decoction, a compound traditional Chinese herbal medicine, on collagen metabolism of hepatic tissues in rats with carbon tetrachloride (CCl(4))-induced liver fibrosis. Methods: Liver fibrosis was induced in rats by intraperitoneal injection of 50% CCl(4)-olive oil solution at a dose of 1 mL/kg body weight, twice per week for 9 consecutive weeks. Six rats were sacrificed for dynamic observation at the end of the 3rd and 6th week respectively, and the other rats were divided into 9-week untreated group and Yiguanjian Decoction group which was given Yiguanjian Decoction intragastrically in the subsequent 3-week modeling period. Another 6 rats were used as normal group. Rats in the normal group and 9-week untreated group were treated with distilled water. At the end of the 9th week, all rats were sacrificed, and their blood serum and liver tissue were collected for measuring hepatic histology and expressions of α-smooth muscle actin (α-SMA), tissue inhibitor of metalloproteinase (TIMP)-1, TIMP-2, matrix metalloproteinase (MMP)-13, MMP-14, collagen type I (Col I), and activities of MMP-2 and -9. Results: Compared with the normal group, collagen fiber deposition, expressions of α-SMA, Col I, TIMP-1, TIMP-2, MMP-13 and MMP-14 and activities of MMP-2 and -9 in the liver tissues gradually increased in the untreated group (P<0.05, P<0.01). These changes were significantly suppressed by Yiguanjian Decoction. Conclusion: Yiguanjian Decoction exerts inhibition on formation of CCl(4)-induced cirrhosis in rats. The therapeutic mechanism may be related to inhibiting hepatic stellate cell activation, collagen secretion, and promoting collagen fiber degradation.

OBJECTIVE: To observe the effects of Jianpi Huoxue Decoction, a compound Chinese herbal medicine, on Kupffer cell signal pathway activation in rats with liver injury induced by Lieber-Decarli liquid diet and lipopolysaccharide (LPS). METHODS: SD rats were divided into normal, control liquid diet, ethanol liquid diet and ethanol liquid diet plus Jianpi Huoxue Decoction group. Rats were administrated with Jianpi Huoxue Decoction or distilled water via gastrogavage for 4 weeks after administration with ethanol or control liquid diet for 2 weeks respectively. After that, rats in each group were stimulated with LPS via gastrogavage for 3.5 h and harvested. Alanine aminotransferase (ALT) in serum and triglyceride (TG) in liver were analyzed. Pathological changes in liver tissues were observed in HE staining section. Tumor necrosis factor-alpha(TNF-alpha) in portal vein plasma was assayed by ELISA. The protein expressions of CD68, Toll-like receptor 4 (TLR4), phosphorylation-I kappa B (P-I kappa B) and TNF-alpha in liver were evaluated with Western-blotting. RESULTS: After the treatment with Jianpi Huoxue Decoction, the pathologic changes in liver tissue were lightened, levels of ALT in serum, TG in liver and TNF-alpha in portal vein plasma were decreased, and the protein expressions of CD68, TLR4, P-IkappaB and TNF-alpha in liver were reduced. CONCLUSION: Jianpi Huoxue Decoction can inhibit Kupffer cell signal pathway activation in rats with liver injury induced by Lieber-Decarli liquid diet and LPS.

OBJECTIVE: Duplicating the classical alcoholic hepatic injury model, to provide an ideal animal model for research on prevention and treatment of hepatic injury. METHODS: According to the prescription of Lieber-DeCarli, the same calorie fluid animal feed, which contained ethanol or non-ethanol, was prepared. Twenty-three rats were divided into normal control group (n=5), control liquid diet group (n=9), ethanol liquid diet group (n=9). Rats in the normal control group were fed normal diet, and rats in the control liquid diet group and ethanol liquid diet group were fed the corresponding diet for eight weeks. The pathologic changes of hepatic tissue were observed. The activities of the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the liver tissue gamma-glutamyltransferase (gamma-GT), the content of triglyceride (TG), and the lipid peroxidation by-products were assayed. RESULTS: Compared to the normal control and the control liquid diet groups, the activities of ALT, AST, and gamma-GT, and the lipid peroxidation by-products increased significantly in the ethanol liquid diet group. The pathological changes of cellular swelling and fatty degeneration in the ethanol liquid diet group were severe. CONCLUSION: Alcoholic hepatic injury model can be successfully duplicated by Lieber-DeCarli prescription.

Objective To retrospectively analyze the prognostic factors for locoregionally recurrent early?stage extranodal nasal?type natural killer/T?cell lymphoma ( NKTCL) . Methods A total of 56 patients with early?stage extranodal nasal?type NKTCL, who had locoregional recurrence after initial treatment and then received salvage treatment from 1995 to 2014, were enrolled as subjects. The effects of salvage treatment on the overall survival ( OS) rate were analyzed after initial treatment and recurrence. Univariate and multivariate prognostic analyses were performed on the OS rate after recurrence. Results The median follow?up time was 35. 9 months after initial treatment and 14. 8 months after recurrence. The 3?year OS rate was 73% after initial treatment and 58% after recurrence. Compared with chemotherapy alone, radiotherapy?containing salvage treatment significantly improved the OS rates after initial treatment and recurrence ( P=0. 040, 0. 009 ) , and re?irradiation also significantly improved the OS rates after initial treatment and recurrence (P=0. 018, 0. 019). Most (84%) of the acute and late adverse reactions after re?irradiation were grade 1?2 ones. The univariate and multivariate analyses showed that the Karnofsky Performance Status score, radiotherapy in initial treatment, and radiotherapy in salvage treatment were influencing factors for the OS rate after recurrence. Conclusions Radiotherapy achieves improved survival and tolerable toxicities, making it indispensable in the treatment of locoregionally recurrent extranodal nasal?type NKTCL.
