Objective To optimize refinement of water extract from Bushen Yangxue Granules by chitosan flocculation.Methods According to the content of icariin detected by HPLC, the waters amount, extraction time and extraction times were evaluated by orthogonal design. The effects of the solution concentration, clarifying temperature and the amount of clarifying agent on the flocculation clarification processes were optimized with the content of icariin and polysaccharides.Results The optimum water extraction processes A2B1C3 were follows: 10 times amount of water, three times extraction and 1 h for each extraction process. The optimized flocculation clarification processes A1B2C3 were as follows: solution concentration was 0.4 g/mL, the clarifying temperature was 40℃ and the addition of chitosan was 0.1%.Conclusion The optimized refining process is stable and feasible.

Objective: To explore the correlation between serum level of high molecular weight adiponectin (HMW-ADPN) and arteriosclerosis. Methods: Clinical data of 87 middle-aged and aged people living in home, who underwent health examinations in Xiangya second hospital from Jan 2011 to Dec 2011, were collected. According to carotid-femoral pulse wave velocity (cf-PWV) = 9 m/s, they were divided into group A (cf-PWV<9 m/s, n=21) and group B (cf-PWV≥9 m/s, n=66). Blood pressure, blood lipid, blood glucose etc. were measured and compared between two groups. Results: Compared with group A, there were significant rise in blood pressure, levels of low density lipoprotein cholesterol, triglyceride and total cholesterol, and significant reduction in levels of high density lipoprotein cholesterol (HDL-C), serum total ADPN and HMW-ADPN in group B, P<0.05 or <0.01. Multiple regression analysis indicated that serum HMW-ADPN (B= - 4.469，P=0.011), total ADPN ((B= - 3.965，P=0.012), HDL-C（B= - 2.077，P=0.015) and systolic blood pressure levels (B= 0.045，P=0.045) were independent predictors of cf-PWV. Conclusion: Serum high molecular weight adiponectin and total adiponectin levels may be protective factors against arteriosclerosis. Its role in predicting occurrence and development of arteriosclerosis is worthy of further study.

Objective: To explore the relationship between monocyte-to-lymphocyte ratio (MLR) in peripheral blood of patients with pulmonary sarcomatoid carcinoma (PSC) and their clinicopathological features and prognosis, and to investigate its clinical significance. Methods: A retrospective analysis was carried out to analyze the complete case data of 80 patients with PSC from October 2010 to April 2017 in Tianjin Cancer Hospital (monocyte and lymphocyte counts of peripheral blood, clinicopathological features, and survival follow-up). The receiver operating curve (ROC) was used to determine the best cut-off value of MLR for the prediction of overall survival time (OS). The patients were divided into high MLR group and low MLR group. Kaplan-Meier method was used to calculate OS and draw survival curves. The Log-Rank test was used to compare the difference in OS between the two groups. The variables with statistical significance in univariate analysis were included into the COX risk regression model to verify and calculate thehazard ratio (HR)and 95% confidence interval (95%CI). Results: The absolute median values of monocytes and lymphocytes were 0.63×109/L and 1.84×109/L, respectively. The best cut-off value of MLR is 0.44. Univariate analysis shows that MLR≥0.44 (P<0.01), no radical surgery (P<0.01), clinical stage Ⅲ+Ⅳ (P<0.01), tumor maximal diameter > 3 cm (P<0.01), and LDH>247 U /L (P<0.01) are the poor prognostic factors affecting overall survival. Multivariate analysis shows that MLR≥0.44（HR=3.554; 95%CI=1.671-6.125; P<0.01), and clinical stage Ⅲ+Ⅳ（HR=3.275; 95%CI=2.047-9.399; P<0.01) are the independent risk factors for the overall survival of PSC, and radical surgery is an independent protective factor affecting the overall survival of PSC（HR=0.360; 95%CI=0.195-0.848; P<0.01). Conclusion: High MLR is an independent risk factor for poor prognosis in patients with PSC.

[Abstract] Objective: To explore the relationship between the preoperative blood indicators (platelets, monocytes, neutrophils-to-lymphocyte ratio) and clinicopathological characters and the prognosis of the early stage malignant melanoma（MM）patients. Methods: Clinicopathological data of 120 cases of stage I-III MM patients, who received initial treatment and radical operation in the Cancer Hospital of Tianjin Medical University from January 2007 to May 2012, were obtained for this study. The correlations between parameters of PLR (platelet-to-lymphocyte ratio), LMR (lymphocyte-to-monocyte ratio), NLR (neutrophil-to-lymphocyte ratio), hemoglobin, neutrophils, lymphocytes, monocytes, eosinophils, basophils, platelets, lactate dehydrogenase, age, stage as well as ulcer and the prognosis of the patients were evaluated. Results: Patients whose tumor with ulceration have higher NLR and basophilic granulocyte (all P< 0.05）. Univariate analysis showed that NLR, PLR, LMR, neutrophil, lymphocyte, monocyte, lactic dehydrogenase, age, stage and ulceration were the risk factors of poor 5-year overall survival (P<0.05). The multivariate analysis identified PLR（HR=4.206， 95%CI:1.65410.696， P<0.01），stage（HR=7.670， 95%CI:3.977-14.795， P<0.01）and ulceration（HR=1.931， 95%CI:1.029-3.623， P<0.05）as independent risk factors for the prognosis of the MM patients. Conclusion: Higher preoperative PLR can be used as a predictive factor for poor prognosis of the early stage MM patients.
