ObjectiveTo explore the formulation rules for the treatment of heart pain in the Medical Heart Enlightenment （《医学心悟》） from the perspective of the "Tangye Jingfa Tu"， thereby providing a way of thinking about the treatment of heart pain in traditional Chinese medicine （TCM） and the study of the Medical Heart Enlightenment. MethodThe "Tangye Jingfa Tu" contained in the Secrets for Auxiliary Cultivation Life： The Essential Method of Using Herbal Medicine for the Differential Treatment of the Five Zang Organs （《辅行诀五脏用药法要》） was used to analyze the nine prescriptions for heart pain in Volume Ⅲ of the Medical Heart Enlightenment by CHENG Guopeng in the Qing dynasty. A "table for analyzing the formulation of the nine prescriptions for heart pain" was developed. The analysis diagrams for decoction and meridian rules in nine prescriptions for heart pain were plotted and the compatible structure of the medicinal flavors was analyzed. ResultThe composition of Chenxiang Jiangqisan for the treatment of Qi-induced heart pain is "five pungent， four bitter， and two sweet drugs"， the composition of Shouniansan for the treatment of blood-induced heart pain is "five bitter， four pungent， three sweet， and one salty drugs"， the composition of Qingzhongtang for the treatment of heat-induced heart pain is "six bitter， three pungent， and two sweet drugs”， the composition of Jiangfutang with Cinnamomi Cortex for cold-induced heart pain is "three pungent and two sweet drugs"， the composition of Xiaobanxia modified with Fuling Tang for treating fluid retention-induced heart pain is "two pungent and two sweet drugs"， the composition of Baohetang for treating heart pain due to dietary stagnation is "five sweet， four pungent， four bitter， and one sour drugs"， the composition of Guipitang for the treatment of deficiency-induced heart pain is "eight sweet， four bitter， three pungent， and one sour drugs"， the combination of Huachongwan for the treatment of worm-induced heart pain is "seven bitter， six pungent， and four sweet drugs"， the composition of Shenzhusan， Congbaijiu， and Shengjiangtang for the treatment of resistance-induced heart pain is "eight pungent， four bitter， and two sweet drugs". ConclusionFrom the perspective of the "Tangye Jingfa Tu"， the Medical Heart Enlightenment is based on the compatibility principle of "pungent-bitter-sweet drugs" in the treatment of heart pain， with heart deficiency treated with salty drugs for tonifying， or bitter-sweet-salty drugs， and heart excess treated with bitter drugs for purging， or sweet-pungent-bitter drugs， mostly applying the transformation rules of five medicinal flavors， i.e.， "sweet-pungent-bitter drugs" and promoting the action of the pungent and sweet drugs acting on the spleen into the heart to relieve and purge the heart. In most cases， the treatment focuses on harmonizing the heart， liver， spleen， and kidneys， with an emphasis on the mother-child relationship and the application of the principles of the five elements generating and controlling each other. If the progression of the disease involves both the mother and child organs， the formulation should adhere to the compatibility rule of "the child organ makes the mother organ excess and the mother organ makes the child organ deficient".

Objective:To explore the medication regularity and prescription rule of Chinese herbal medicine in the treatment of cardiac failure.Methods:The China Patent Publication Notice of the State Intellectual Property Office (http://epub.sipo.gov.cn/) was rearched and retrievedfor Chinese herbal medicine for the treatment of heart failure. The Traditional Chinese Medicine (TCM) inheritance support system (V 2.5) was used to input the prescription information and establish the database. The association rules, mutual information method, entropy clustering of complex systems and other data mining methods were used for commonly used drugs, combination rule and new prescription of core group.Results:A total of 101 prescriptions were included, involving 316 drugs. The frequency of commonly used drugs were Astragali Radix (59.41%), Poria (41.58%), Salviae Miltiorrhizae Radix et Rhizoma (40.59%), Descurainiae Semen Lepidii Semen (34.65%), Aconiti Lateralis Radix Praeparata (33.66%), and the medicinal properties were mainly warm, and the sweet taste. The main flavors weresweet, bitterness, and pungency, and the main sources of meridians belonged to liver, spleen, heart, lungs and kidneys. The most commonly used drug combinations contribute to supplement Qi, invigorate blood circulation and stasis, warm Yang, remove moisture. There were 12 core drug groups and 6 new prescriptions for heart failure. Conclusions:Analysis on formulas for heart failure shows that the prescriptions focus on supplementing qi and activating blood circulation, warming Yang reducing dampness, invigorating spleen, and nourishing Yin, dispel turbid, solid Yang. It can provide reference for clinical treatment to improve curative effect and standardize prescription medication.

Objective:To investigate the sodium intake, potassium intake, sodium- potassium ratio and influencing factors of family cooks and members in six regions of China.Methods:Using the multistage random sampling method, a total of 1 576 family cooks and their family members were recruited from 6 regions in China. Questionnaire survey and physical examination were conducted to collect basic information. 24 h urine was collected to test 24 h urinary sodium and potassium levels.Results:After excluding unqualified urine samples, a total of 1 530 people were included in the study. For all participants, 24 h urine sodium value was (4.39±1.93) g, 24 h urine potassium value was (1.59±0.62) g and sodium-potassium ratio was 5.02±2.18. 24 h urinary sodium was negatively correlated with age, female, junior high school education or above, and annual family income ( P<0.05), and positively correlated with perceived salty taste, BMI and SBP ( P<0.05). The 24 h urine potassium value was negatively correlated with eating out almost everyday ( P<0.05), but positively correlated with BMI and unwillingness to reduct salt ( P<0.05). The sodium-potassium ratio was negatively correlated with age, female and junior high school education or above annual family income ( P<0.05), and positively correlated with perceived salty taste, SBP and eating out 3-5 d/week ( P<0.05). Conclusions:The 24 h urinary sodium value and sodium potassium ratio of family cooks and family members in six regions of China are still at high level, while the 24 h urine potassium value is low, with multiple factors. Therefore, it is necessary to carry out long-term comprehensive salt reduction intervention for family cooks and their members.

Salt reduction is the most cost-effective population strategy to prevent and control hypertension and cardiovascular disease. Accurate measurement of salt intake is an important basis for implementing salt reduction interventions, while the urine sodium measurement is the most objective method to evaluate salt intake. According to different time spans, it is mainly divided into 24-h urine, overnight urine and spot urine collection methods. This article reviewed the application and evaluation of these three urine measurement methods, and compared their advantages and disadvantages. According to the accuracy and feasibility of different urine measurement methods, it is suggested that the 24-h urine collection method can be applied to the correlation study with small sample size, and the overnight urine method and the spot urine method can be applied to the daily population salt reduction interventions and monitoring activities.

Objective To investigate the expressions of PGE2 and COX-2 between colorectal cancer tissue and normal colorectal mucosa tissue,and its relation to clinical pathology and significance.Methods 115 colon cancerous tissues and 69 normal colon tissues were collected in our hospital from Jan 2010 to Sept 2011.Immunohistochemistry was used to detect the PGE2 and COX-2 expression in both of the colorectal cancer and normal tissues.Results Positive expressions of PGE2 and COX-2 were 87.8％ (101/115) and 80.9％ (93/115) in the colorectal cancer tissue,and 8.7％ (6/69),21.7％ (15/69) in normal colorectal mucosa tissue respectively (x2 =110.96,62.194,all P ＜ 0.05).Expressions of PGE2 and COX-2 were closely associated with,tumor invasion,differentiation,lymph node metastasis and TNM stage (P ＜ 0.05).The Spearman rank correlation analysis indicated that the PGE2 and COX-2 expressions in tissues were closely correlated (r =0.987,P ＜ 0.05).Survival rate of the patients in both negative expressions of PGE2 and COX-2 (63.6％) were higher than that of both positive expressions (37.8％,P ＜ 0.05).Conclusion High PGE2 and COX-2 expressions in colorectal cancer tissues predicts poor patients' survival.

OBJECTIVETo investigate the effects of polyunsaturated fatty acids (PUFA) ω-3 and ω-6, and their middle metabolites PGE2 and PGE3 on angiogenesis formation of gastric cancer, and to explore associated mechanism.

METHODSThe effects of ω-3, ω-6, PGE2, PGE3 on the proliferation and migration of human umbilical vein endothelial cell (HUVEC) were measured by proliferation and migration assay respectively. The angiogenesis assay in vivo was used to measure the effects of ω-3, ω-6, PGE2 and PGE3 on neovascularization. In all the assays, groups without ω-3, ω-6, PGE2 and PGE3 were designed as the control.

RESULTSWith the increased concentration of ω-6 from 1 μmol/L to 10 μmol/L, the proliferation ability of HUVECs enhanced, and the number of migration cells also increased from 28.2±3.0 to 32.8±2.1, which was higher than control group (21.2±3.2) respectively (both P<0.05). With the increased concentration of ω-3 from 1 μmol/L to 10 μmol/L, the proliferation ability of HUVECs was inhibited, and the number of migration cells decreased from 15.8±2.0 to 11.0±2.1, which was lower than control group (22.1±3.0) respectively (both P<0.05). In the angiogenesis assay, compared with control group (standard number: 43 721±4 654), the angiogenesis ability of HUVECs was significantly enhanced by ω-6 in concentration-dependent manner (1 μmol/L group: 63 238±4 795, 10 μmol/L group: 78 166±6 123, all P<0.01). Meanwhile, with the increased concentration of ω-3 from 1 μmol/L to 10 μmol/L, the angiogenesis ability was significantly decreased from 30 129±3 102 to 20 012±1 541(all P<0.01). The proliferation and migration ability of HUVECs were significantly promoted by ω-6 metabolites PGE2 (P<0.05) in a concentration-dependent manner. In contrast, ω-3 metabolites PGE3 significantly inhibited the proliferation and migration ability of HUVECs in a concentration-dependent manner (all P<0.05). After rofecoxib (a COX-2 specific inhibitor) inhibited the expression of COX-2, the expression level of PGE2 was significantly decreased in a dose-dependent manner. In co-culture system, whose gastric cancer cells expressed positive COX-2, ω-6 could increase angiogenesis of gastric cancer cells(P<0.01), but ω-3 could inhibit such angiogenesis(P<0.01). In co-culture system, whose gastric cancer cells did not express COX-2, ω-3 could inhibit the angiogenesis of gastric cancer cells (P<0.05), but ω-6 had no effect on angiogenesis.

CONCLUSIONSThe PUFA ω-6 can enhance the angiogenesis via the promotion of proliferation and migration of HUVECs, and COX-2 and PGE2 may play an important role in this process, whereas, the ω-3 can inhibit the angiogenesis through its middle metabolites PGE3 to inhibit the proliferation and migration of HUVECs. Results of this experiment may provide a new approach to inhibit and prevent the spread of gastric cancer.

OBJECTIVETo explore the effect of colon cancer cell-derived interleukin-1α on the migration and proliferation of human umbilical vein endothelial cells as well as the role of IL-1α and IL-1ra in the angiogenesis process.

METHODSWestern blot was used to detect the expression of IL-1α and IL-1R1 protein in the colon cancer cell lines with different liver metastatic potential. We also examined how IL-1α and IL-1ra influence the proliferation and migration of umbilical vascular endothelial cells assessed by PreMix WST-1 assay and migration assay, respectively. Double layer culture technique was used to detect the effect of IL-1α on the proliferation and migration of vascular endothelial cells and the effect of IL-1ra on the vascular endothelial cells.

RESULTSWestern blot analysis showed that IL-1α protein was only detected in highly metastatic colon cancer HT-29 and WiDr cells, but not in the lowly metastatic CaCo-2 and CoLo320 cells.Migration assay showed that there were significant differences in the number of penetrated cells between the control (17.9±3.6) and 1 ng/ml rIL-1α group (23.2±4.2), 10 ng/ml rIL-1α group (31.7±4.5), and 100 ng/ml rIL-1α group (38.6±4.9), showing that it was positively correlated with the increasing concentration of rIL-1α (P<0.01 for all). The proliferation assay showed that the absorbance values were 1.37±0.18 in the control group, and 1.79±0.14 in the 1 ng/ml rIL-1α group, 2.14±0.17 in the 10 ng/ml rIL-1α group, and 2.21±0.23 in the 100 ng/ml rIL-1α group, showing a positive correlation with the increasing concentration of rIL-1α(P<0.01 for all). IL-1ra significantly inhibited the proliferation and migration of vascular endothelial cells (P<0.01). The levels of VEGF protein were (1.697±0.072) ng/ml, (3.507±0.064)ng/ml and (4.139±0.039)ng/ml in the control, HUVECs+ IL-1α and HUVECs+ HT-29 co-culture system groups, respectively, showing a significant difference between the control and HUVECs+ 10 pg/ml rIL-1α groups and between the control and HUVECs+ HT-29 groups (P<0.01 for both).

CONCLUSIONSOur findings indicate that colon cancer cell-derived IL-1α plays an important role in the liver metastasis of colon cancer through increased VEGF level of the colon cancer cells and enhanced vascular endothelial cells proliferation, migration and angiogenesis, while IL-1ra can suppress the effect of IL-1α and inhibit the angiogenesis in colon cancer.
