Objective To investigate the expression and clinical significance of P-selectin in colorectal cancer cells. Methods The protein expression of P-selectin was detected by immunohistochemistry in colorectal cancer tissues ( n=116) and corresponding non-tumor normal mucosa(n=57). The differences of P-selectin expression in colorectal cancer tissues, corre?sponding non-tumor normal mucosa and the clinical pathological significance were compared and analysed in two groups. Results The expression of P-selectin protein was found not only in vascular endothelial cells but also in colorectal cancer cells. The positive rate of P-selectin expression was apparently higher in colorectal cancer cells (77.6%, 90/116) than that in normal mucosa (17.5%, 10/57,χ2=56.49, P<0.05). However, there were no significance in positive rates of P-selectin in colorectal cancer cells between tumors with different diameters, different degrees of differentiation, different depths of infiltration and with or without lymph node metastasis (80.6%vs. 74.1%, 79.0%vs. 74.3%, 78.4%vs. 76.9%, 82.7%vs. 73.4%, P>0.05). Conclusion The high expression of P-seletin in colorectal cancer cells is an important characteristic of colorectal cancer.

A method of direct injection and liquid chromatography coupled with tandem mass spectrometric (LC-MS / MS) was developed for simultaneous determination of 5 aniline compounds including aniline, 3-nitroaniline, 4-nitroaniline, 2,6-dichloro-4-nitroaniline and hexanitrodiphenylamine in drinking water and source water. The samples were filtered using a 0. 22-μm polyethersulfone membrane prior to HPLC analysis. Five target compounds were chromatographically separated on an HSS T3 column with gradient elution. Chromatographic data were acquired by tandem mass spectrometric detection in multiple reaction monitoring (MRM) mode, and thus favorable resolutions of all target compounds were achieved within 4 min. Under the optimal analytical conditions, the peak area of each analyte and its concentration had a good correlation within the linear range (R≥0. 995). The limit of detection (LOD) and limit of quantification (LOQ) of the method were 0. 773-1. 88 μg / L (S / N=3) and 2. 58-6. 27 μg / L (S / N=10), respectively. The intra- and inter-day relative standard deviations ( RSDs) of the mix standard solution were 0. 8% -1. 9% and 3. 3% -4. 9% , respectively. The spiked recoveries of the analytes were 84. 1% -105% and the RSDs of the spiked samples were 1. 0% -3. 1% . This proposed method was applied in the analysis of 35 samples from drinking water, source water and surface water, which indicated that the novel LC-MS / MS method could detect 5 aniline compounds in water without any complicated sample pretreatment in an accurate, sensitive and rapid way, and it also could provide technique support for evaluation of the contamination caused by aniline compounds.

With the increasing incidence and mortality of coronary heart disease (CHD) in China, the prevention and treatment of CHD is no time to delay. Since Professor Gruentzig completed the first human case of percutaneous transluminal coronary angioplasty (PTCA) in 1977, percutaneous coronary intervention (PCI) had reached to a new page. After three decades of development and change, PCI has been improved and matured gradually from the early PTCA to the current stent era. With the advent of stents, the rate of restenosis after PCI was significantly reduced from 30%-50% to 10%-20%. But stent restenosis was still with no total cure. The issue of how to prevent the stent restenosis has become a long-term major issue for the exploration in both clinical and preclinical medicine. Therefore, this paper reviewed the etiology, pathology, related risk factors, latest diagnosis methods, prevention and treatment of stent restenosis by integrative medicine.

This study was aimed to observe the safety and effectiveness ofShugan Jieyu Capsules in the treatment of vasovagal syncope (VVS) with mild-to-moderate depression and anxiety, and to compare the effect with Flupentixol and Melitracen Tablets. A total of 89 VVS cases with mild-to-moderate depression and anxiety were randomly divided into 3 groups, which were group A (Shugan Jieyu Capsules group), group B (Flupentixol and Melitracen Tablets) and group C (control group). Based on the conventional therapy of VVS treatment, treatments were given to all three groups for 8 weeks. And the negative conversion ratio of VVS in each group was observed. Hamilton Depression Scale (HAMD 24 items) and Hamilton Anxiety Scale (HAMA) were evaluated for the calculation of reductive rate. Treatment emergent symptoms scale (TESS) was used in the evaluation of adverse reactions of both medications during the treatment. In the 12-month follow-up after treatment, the recurrence rate of syncope was observed in each group. The results showed that compared with pretreatment, HAMD-24 and HAMA scores of group A and group B after treatment were significantly reduced (P < 0.05). Compared with group C, the heat-up tilt testing-negative rate, HAMD-24 and HAMA reductive rate of group A and group B after treatment were significantly increased (P < 0.05). Compared with group B, the negative rate, HAMD-24 and HAMA reductive rate of group A were more significant (P < 0.05). After treatment, scores for TESS of group A was significantly lower than group B (P< 0.05). In the 24-month follow-up, the recurrence rate of syncope of group A and group B was significantly lower than group C (P < 0.05); and group A was obviously better than group B (P < 0.05). It was concluded thatShugan Jieyu Capsules can be used in the treatment of VVS with mild-to-moderate depression and anxiety. Its effectiveness and safety may be better than Flupentixol and Melitracen Tablets.

This study was aimed to investigate the effect ofDanlou pills on prevent atherosclerosis from hypercholesterolemia rabbit and its relationship with inflammatory factors as well as PI3K/AKT signal pathways. A total of 24 Japanese male white rabbits were randomly divided into the control group (CL), model group (M) and Danlou group (DL), with 8 in each group. Normal diet was given to CL rabbits. High-fat diet was given to rabbits in other groups to establish the atherosclerosis model. Danlou pills (0.5 g·kg-1·d-1) were also given to DL rabbits. Rabbits were sacrificed after 9-week medication. The contents of blood lipid, TNF-α and IL-6 were detected. HE staining was used in the observation of histological changes in the aorta. Western blot was used to observe PI3K and p-AKT expression in the aorta. The results showed that compared with CL, the contents of TG, TC, LDL, IL-6 and TNF-α were significantly increased in M (P < 0.01); PI3K and p-AKT expression in the aorta were significantly decreased (P < 0.01). Compared with M, blood lipid, IL-6 and TNF-α were significantly reduced in DL (P < 0.05, orP < 0.01); PI3K and p-AKT expression were significantly increased (P < 0.01). It was concluded thatDanlou pills had prevention effects on atherosclerosis through reducing blood lipid and inflammatory factors. The action mechanism maybe related to the activation of PI3K/AKT signal pathways.
