Pulse-taking is the most specific diagnostic method of TCM.Its significance has been recognized by ancient and modern doctors.However,at present the application and spread of pulse-taking is limited.In this paper,the author made detailed explorations of literatures and studies the value of pulse condition in guiding syndrome differentiation of liver diseases.The study shows abnormal pulse in left guan and taut pulse in cunkou location both suggest the liver is disordered.We can judge the location of diseases through pulse condition.This exploration shows pulse-taking plays important role in syndrome differentiation.But there is one thing should be paid more attention,pulse condition should be integrated with other symptoms,that will be reliable in guiding diagnosis.

BACKGROUND: Polysaccharide sulfate has bean hot focus in recent research.Regarding anticoagulant property of sulfated polysaccharides, recent studies mainly explored degree Of substitution, and there are rare studies concerning relative molecular mass and spatial structure.OBJECTIVE: To study the anticoagulant activity of the sulfated agarose with different relative molecular masses.METHODS: With formamide as dispersing agent,agarose was sulfated with the method of chlor0sulfonic acid-pyridine.The product was graded and purified with dialysis bag.Two kinds of sulfated agarose with different molecular masses were obtained,and their anticoagulant properties were checked by assays of the activated partial thromboplastin time,thrombin time.RESULTS AND CONCLUSION:.Two kinds of sulfated agarose had similar degree of substitution and sulfation position,whereas their molecular weight was different.The bioassay results of coagulation index demonstrated that the anticoagulant activity of agarose improved with the increasing of molecular mass within a certain range.Relative molecular mass had an important effect on the anticoagulant activity of the sulfated agarose.

AIM:To explore the polarized distribution of M 2 macrophages in the marginal region around lung adenocarcinoma , the marginal/central ratio and their effect on the prognosis .METHODS:Double immunohistochemistry staining was used to determine the distribution and the difference of CD 163 +/CD68 +( M2 ) macrophages in the marginal and central regions in 49 cases of lung adenocarcinoma in situ ( AIS), 11 cases of minimally invasive adenocarcinoma ( MIA) and 57 cases of invasive adenocarcinoma ( IA) in order to explore the effect and mechanism of the polarized distri-bution and the marginal/central ratio on the progression of lung adenocarcinoma .Single-factor Kaplan-Meier survival curve analysis and multivariate Cox survival analysis were employed to explore the relationship between the polarized distribution of M2 macrophages and the prognosis .RESULTS:Polarized aggregation of M 2 macrophages was observed in the marginal region of lung adenocarcinoma compared with that in the central region , and the difference was significant ( P<0.01 ) . Based on the median level , they were divided into high polarized group and low polarized group .In low polarized group , M2 macrophage count in AIS was not significantly different from that in MIA or IA .However, in high polarized group, M2 macrophage count in AIS was lower than that in MIA and IA in turn and there were statistically significant differences (P<0.01).Single-factor Kaplan-Meier survival curve analysis and log-rank test result showed that the number of M2 mac-rophages in the marginal region and marginal/central ratio were negatively correlated to the survival time (χ2 =44.71, P<0.01;χ2=21.75, P<0.01).Multivariate Cox survival analysis showed that the high polarized distribution of M 2 macro-phages in the marginal region and the marginal /central ratio were independent risk factors for the prognosis ( P<0.01 ) . CONCLUSION:There is a polarization effect of M2 macrophages on the marginal region of lung adenocarcinoma .The marginal polarization and the marginal/central ratio are independent risk factors of the prognosis .Therefore , it may be an effective method for the evaluation of the prognosis to judge the marginal polarization by preoperative puncture and to deter -mine the marginal/central ratio of M2 macrophages by postoperative biopsy .

Objective To evaluate the effect of inhalation of hydrogen gas (H2) on Rho/Rho kinase (ROCK) pathway in lung tissues of septic mice with acute lung injury.Methods Forty male C57BL/6 mice,weighing 20-25 g,aged 6 weeks,were randomly divided into 4 groups (n=10 each) using a random number table:sham operation group (group Sh),sham operation + inhalation of H2 group (group H2),sepsis group (group S),and sepsis+ inhalation of H2 group (group S+H2).Sepsis was produced by cecal ligation and puncture (CLP).Both H2 and S+H2 groups inhaled 2％ H2 for 1 h starting from 1 and 6 h after CLP.The mice in each group were sacrificed at 24 h after CLP.The bronchoalveolar lavage fluid (BALF) was collected for determination of protein concentrations,polymorphonuclear neutrophil (PMN) count,and concentrations of tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) (by enzyme-linked immunosorbent assay).The lung tissues were obtained for examination of the pathological changes which were scored and for determination of the wet/dry weight ratio (W/D ratio),activities of myeloperoxidase (MPO) and superoxide dismutase (SOD),malonaldehyde (MDA) level,the expression of Rho,ROCK1,ROCK2 and activated caspase-3,and phosphorylation of myosin phosphatase target protein 1 (MYPT-1) (by Western blot).Results Compared with group Sh,the concentrations of protein,PMN count,and concentrations of TNF-α and IL-1β in BALF,lung injury score,W/D ratio,and levels of MPO and MDA in lung tissues were significantly increased,the activity of SOD in lung tissues was significantly decreased,the expression of Rho,ROCK1,ROCK2 and activated caspase-3 was significantly upregulated,and the phosphorylation of MYPT-1 in lung tissues was significantly increased in S and S+H2 groups (P＜0.05),and no significant change was found in the parameters mentioned above in group H2 (P＞0.05).Compared with group S,the concentrations of protein,PMN count,and concentrations of TNF-α and IL-1β in BALF,lung injury score,W/D ratio,and levels of MPO and MDA in lung tissues were significantly decreased,the activity of SOD in lung tissues was significantly increased,the expression of Rho,ROCK1,ROCK2 and activated caspase-3 in lung tissues was significantly down-regulated,and the phosphorylation of MYPT-1 in lung tissues was significantly decreased in group S+H2 (P＜0.05).Conclusion The mechanism by which inhalation of H2 attenuates acute lung injury is related to inhibition of Rho/ROCK pathway activation in lung tissues of septic mice.

Objective To investigate the effect of slice orientation on the popliteomeniscal fasciculi (PMF) MR imaging and its normal MRI appearances. Methods Volumetric MRI data of 40 knees of healthy volunteers were acquired using an isotropic 3D turbo spin echo (TSE) MR sequence. The posterior tangential line to both femoral condyles was used as the reference line, and the long axis sectional images of the popliteal hiatus region were reformatted at 0°, 15°, 30°, 45°, 60°, 75° and 90° to the reference line. The MRI appearances of the PMF were scored respectively and classified. The final scores of the PMF at each slice angle were statistically analyzed by a repeated measure ANOVA. Results At 0°, 15°, 30°, 45°, 60°, 75° and 90° slice angles: scores of the anteroinferior fasciculi were (1.7±0.7), (1.8±0.6), (1.9±0.6), (2.0±0.7), (1.9±0.7), (1.8±0.8) and (1.0±0.5),respectively. Scores of the posterosuperior fasciculi were (1.5±0.7), (1.9±0.7), (2.1±0.6), (2.2±0.6),(2.2±0.6), (2.0±0.8) and (1.7±0.8), respectively. There were statistically significant differences in the average scores at each slice angle for both anteroinferior fasciculi (F = 29.744, P = 0.000) and posterosuperior fasciculi (F = 19.770,P =0.000). The anteroinferior fasciculi and the posterosuperior fasciculi had highest average scores at the angle of 45°. The percentage of type A, B and C of anteroinferior fascicali were 20.0% (8/40), 75.0% (30/40) and 5.0% (2/40), respectively. The percentage of type A, B and C of posterosuperior fasciculi were 37.5% (15/40) ,62.5% (25/40) and 0% (0/40) ,respectively. Conclusion The anteroinferior fasciculi and the posterosuperior fasciculi can be well depicted at the angle of 45° slice orientation.
