Objective To explore the composition and distribution law of TCM syndromes in gastric cancer. Methods Based on the multicenter and large-sample clinical epidemiological investigation, the four methods of diagnosis of and clinical materials of 767 cases of gastric cancer were collected, and the database of TCM syndromes in gastric cancer was establish. Factor analysis and clustering analysis were used to explore composition and distribution law of TCM syndromes in gastric cancer. Results Gastric cancer symptoms mainly included fatigue, weight loss, dizziness and other non-specific systemic manifestation, and epigastria discomfort, belching, fullness or eating just a little swelling, pain, acid regurgitation, loss of appetite and other local manifestations. At the same time, the red tongue, moss greasy, pulse fine or string and other traditional Chinese medicine signs were also included. Eliminating 92 cases with too little symptoms, 675 cases were under multivariate analyzed. 25 syndrome variables were selected after initial factor analysis, again through factor analysis 10 factors with eigenvalues more than 1.0 were obtained and the cumulative contribution rate was 60.5%. Through further K-means clustering analysis on 10 common factor integrals, it was found that when all the cases were clustered into 7 classes consistent with clinical practice most. The numbers of patients with the 1-7 type were 165, 82, 90, 79, 88, 95 and 76, respectively. Analysis on the main factors in the combination of professional knowledge, the 7 types were named as the syndrome of spleen and stomach qi stagnation (24.44%), the syndrome of qi and blood deficiency (12.15%), the syndrome of spleen deficiency (13.33%), the syndrome of blood stasis (11.70%), the syndrome of phlegm dampness (13.04%), the syndrome of deficiency cold of spleen and stomach (14.07%), the syndrome of incoordination between liver/gallbladder and stomach (11.41%) respectively. Conclusion The results of multivariate analysis suggests that the location of gastric cancer is in the stomach, and closely related to spleen, liver and gallbladder. The general pathogenesis is asthenia in origin and asthenia in superficiality. The deficiency lies in qi, blood and yang qi, while asthenia superficiality owes to stagnation of qi, phlegm and blood stasis.

From original concept and literature of acupoint, the concept and clinical significance of ashi method is discussed, which clarifies that the essence of ashi method is to locate the acupoints by patients' sensitivity on force. The clinical application of heat-sensitive moxibustion has illustrated that positioning method of this therapy is based on the appearance of heat-sensitive moxibustion sensation. Although both types are based on patients' feeling, positioning method of heat-sensitive moxibustion stands on a new angle and uses a new method to locate acupoint. Therefore, it is believed that the positioning method of heat-sensitive moxibustion is the inheritance and development of ashi method.

Bio-active components from Carthamus tinctorius were separated on the basis of antioxidant capacities in vitro. The antioxidant capacity was investigated on the basis of the ability to scavenge DPPH radical, ABTS radical and reduce Fe3+ of different polar fractions. Furthermore, the chemical compounds were isolated from bio-active fraction, and were evaluated for the antioxidative effects. Five major components were isolated and identified from water extract as 6-hydroxykaempferol 3,6,7-tri-O-β-D-glucoside(1), 6-hydroxykaempferol 3-O-β-rutinoside-6-O-β-D-glucoside (2), 6-hydroxykaempferol 3-O-β-D-glucoside (3), hydroxysafflor yellow A (4) and anhydrosafflor yellow B (5). By evaluating and comparing the antioxidative effects of different fractions and obtained compounds, the results showed that water extract displayed significantly high antioxidative activities and 6-hydroxykaempferol glycosides and quinochalcone C-glycosides were found as main contribution for antioxidant property.

AIMTo investigate the effects of NPPB, a chloride channel blocker, on proliferation of mesangial cells.

METHODSCell proliferation was determined by measuring cell number and 3H-thymidine incorporation. The LDH activity released from these cells was measured as evaluation of cell viability. The phase of cell cycle was detected by flow cytometry.

RESULTSCell proliferation assays showed that treatment with both NPPB (50 and 25 micromol x L(-1)) and in hypertonic media (100% increased osmolarity with D-mannitol ) significantly reduced the number of human MC and 3H-thymidine incorporation in a dose-dependent manner. But the LDH activity was not significantly altered in the treatment with 50 micromol x L(-1) NPPB. Flow cytometry experiments showed that 50 and 25 micromol x L(-1) NPPB arrested (84.2 +/- 2.4) % and (80.8 +/- 2.9) % of cells at G0/G1 stage, versus (70.5 +/- 1.4) % of control cells. Conclusion NPPB suppresses cell proliferation and produces growth arrest at G0/G1 phase in human MC by a mechanism probably associated with changes in cell volume.

The study was designed to explore the alteration of intracellular calcium concentration ([Ca²⁺]i), induced by transient receptor potential melastatin 8 (TRPM8) channel-specific agonist menthol, in pulmonary arterial smooth muscle cells (PASMCs) between control and pulmonary hypertensive (PH) rats. PH rat models were established by means of chronic hypoxia (CH) and monocrotaline (MCT) injection, respectively. PASMCs from control and PH rats were cultured. The change of [Ca²⁺]i in PASMCs induced by menthol, and the effect of TRPM8 channel-specific antagonist BCTC on the change of [Ca²⁺]i, were observed. Cellular localization of TRPM8 was examined by using immunohistochemistry. Results showed that menthol increased [Ca²⁺]i in the control PASMCs both in Ca²⁺ -normal and Ca²⁺ - free Tyrode's solutions, and at the same time BCTC could inhibit these two kinds of elevations. Compared with the control group, elevations of [Ca²⁺]i were decreased notably in CH- and MCT-pretreated PASMCs superfused with 2 mmol/L Ca²⁺ - or 0 Ca²⁺ -Tyrode's solutions. Immunohistochemical localization experiments showed that the whole PASMCs were dyed brown except for the nucleus. This study verified that TRPM8 exists both in membrane and sarcoplasmic reticulum of PASMCs. In addition, CH- and MCT-pretreatment could independently down-regulate the Ca²⁺ influx and Ca²⁺ release mediated by TRPM8 channel.
