This study aims to optimize the most effective component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on lung cancer A549 using the orthogonal design method, and to investigate its effects of the component formula on cell proliferation, apoptosis and cytoskeleton in lung cancer A549 cells. The orthogonal design method was introduced to optimize the most effective component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on lung cancer A549 cells. CCK-8 assay and Real-time cell analysis were adapted to analyze the effect of component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on A549 cells viability at different time and dose. Cell apoptosis was measured by Annexin V- FITC/PI double staining and flow cytometry. Cell skeleton protein F-actin was detected by high content screening (HCS). The optimizing component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma for total salvianolic acid, total saponins of panax ginseng and ginseng polysaccharide doses were 5, 10, 5 mg L(-1). CCK-8 assay and real-time cell analysis demonstrated that the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma treatment could significantly decrease the A549 cell viability in both dose- and time-dependent manner compared with control group (P < 0.01). Moreover, the increase of cell apoptosis was detected by Annexin V-FITC/PI double staining and flow cytometry when cells treated with the component formula, which indicating that the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma could induce A549 cell apoptosis in a time-dependent manner compared with control group (P < 0.01). Furthermore, compared with control group, a significant decrease in A549 cell skeleton area was found in the component formula-exposed cells in the dose-dependent manner (P < 0.01). In summary, the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma inhibits A549 cell proliferation by inducing cell apoptosis and decreasing cell microfilament formation. All of these results will be helpful to reveal antitumor mechanism of the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma, which provides a basis for the exploration of antitumor mechanism of the component formula on lung cancer.

Objective: To investigate the effects of sediel on the blood pressure and life quality of hypertension patients with anxiety. Methods: After evaluating 672 cases with essential hypertension by HAD,the subjects with anxiety. were evaluated with HAMA and HAMD. After 8 weeks of baseline assessments the subjects with positive results with HAMA were randomly divided into anti-anxiety therapy group (n=25, routine treatment and Sediel) and control group (n=25, only routine treatment). The effect of blood pressure control, the life quality and the level of anxiety were compared between 2 groups. Results: In anti-anxiety therapy group, the effect of blood pressure control were more stable, and have higher life quality. Conclusion: The anti-anxiety therapy could improve the effect of blood pressure control and life quality of hypertensive patients.

Objective To examine the reliability,validity,and practicability of Cognitive Emotion Regulation Questionnaire (CERQ) in hypertensive patients in China.Methods Altogether 434 hypertensive patients and 462 healthy subjects were recruited. All the subjects were assessed with the CERQ-Chinese version (CERQ-C), Dysfunctional Attitude Scale (DAS), Mood and Anxiety Symptom Questionnaire-Short Form (MASQ-SF), and Center for Epidemiologic Studies Depression Scale (CES-D). We calculated the mean inter-item correlations for the total CERQ and for each of the subscales. Cronbach's alpha coefficient was used to analyze the inter-correlation and reliability, and confirmatory factor analysis was used to examine the 9-factor model. Results 1) Hypertension group reported significantly higher score than that of healthy ones on rumination (12.19±2.51 vs. 11.51±2.60, P<0.001), catastrophizing(8.82±2.19 vs.8.11±2.70,P<0.001),and blaming others(10.76±2.11 vs. 9.88±2.48,P<0.001), and had significantly lower score than that of healthy ones on positive reappraisal(13.80±3.55 vs.14.71±4.11,P<0.001).2)Reliability:In the hypertension group the Cronbach's alpha for the total CERQ was 0.80, and that for the 9 subscales ranged from 0.71 (self-blame) to 0.90 (rumination). In the healthy group the Cronbach's alpha for the total CERQ was 0.79, and that for the 9 subscales ranged from 0.71 (positive reappraisal) to 0.90 (rumination). The mean inter-item correlation coefficient for the 9 subscales was 0.21-0.42(the hypertension group)/0.19-0.32 (the healthy group). In the hypertension group,the test-retest reliability of the total scale was 0.82, the test-retest reliability of the 9 subscales ranged from 0.73 to 0.92. The confirmatory factor analysis showed that the 9 first-order factor data fitted both 2 samples well. Conclusion CERQ meets the psychometric standard and it is reliable and valid for cognitive emotion regulation strategies, which may be regarded as an appropriate assessment tool.

OBJECTIVETo evaluate clinical significance of waist soft tissue tension detection in treating chronic nonspecific low back pain.

METHODSFrom August 2011 to March 2012,60 patients with chronic nonspecific low back pain were divided into two groups (sliver needle group and TCM fumigation group) according to propotion of 1:1. In sliver needle group, there were 17 males and 13 females aged from 28 to 55 years old with an average age of (45.70 +/- 4.15), treated with sliver needle; In TCM fumigation group,there were 19 males and 11 females aged from 27 to 55 years old with an average age of (43.03 +/- 5.86), treated with TCM fumigation. Changes of force-displacement distance (FDD), specific absorption rate (S) of two groups were observed before treatment, 1 week and 3 months after treatment respectively, VAS scoring and Roland-Morris disability questionnaire (RMDQ) were used to access clinical effects.

RESULTS(1) VAS score of silver needle group was 4.77 +/- 0.78, 1.99 +/- 1.08 and 2.55 +/- 0.94, respectively before treatment, at 1 week and 3 months after treatment,while VAS score in TCM fumigation group were 4.43 +/- 0.61, 2.48 +/- 0.71 and 3.05 +/- 0.86, respectively. VAS score of two groups after treatment were sigificant decrease than that of before treatment (P < 0.05). There was no sigificant differences between two groups before treatment, but sliver needle group performed well in analgesia than TCM fumigation group, and had obvious differences (P < 0.05). RMDQ score of silver needle group was 13.63 +/- 1.96, 5.87 +/- 2.33 and 6.53 +/- 2.89, respectively before treatment, at 1 week and 3 months after treatment, while RMDQ score in TCM fumigation group were 13.40 +/- 2.01, 6.90 +/- 2.31, 9.23 +/- 2.87, respectively. There was no significant differences between two groups before treatment and 1 week after treatment (P > 0.05), and had obvious differences between two groups at 3 months after treatment (P < 0.01). Both groups could obvious improve dysfunction caused by chronic low back pain, and curative effect of sliver needle groups was more endurable. (2) Following-up at 3 months after treatment, FDD of multifidus, erector spinae of effected side and multifidus of healthy in sliver needle group were obvious increased (P < 0.05); In TCM fumigation group, FDD of multifidus and erector spinae on both side were increased at 1 week after treatment (P < 0.05), but had no significant meaning at 3 months after treatment on health side (P>0.05). There was no significant meaning before treatment (P > 0.05), FDD of multifidus, erector spinae of effected side in sliver needle group were obvious increased at 1 week after treatment (P < 0.05); but no obvious meaning on health side. FDD of both side in sliver needle group were obvious increased at 3 months after treatment. (3) There was correlation among differences of FDD in multifidus and erector spinae, VAS score and differences of RMDQ, and Spearman correlation coefficient R was 0.517, 0.811, 0.746 and 0.625; There was correlation between items of soft tissue tension and sympotoms, function and life quality. Conclusion:Soft tissue tension detection can effectively manifest degree of pain and dysfunction of low back, and improve objectivity of therapeutic evaluation for chronic low back pain.

Objective to investigate the value of diffusion-weighted echo-planar MR imaging in the diagnosis of head and neck lesions.Methods Fifty-seven patients with 85 head and neck lesions were enrolled in the study,including 22 patients with 22 malignant tumors,13 patients with 13 benign tumors, 13 patients with 17 cystic and liquefactive lesions(including 8 patients with 12 cystic lesions,4 patients with 4 tumor necrosis,1 patients with 1 abcess)and 33 lymph nodes.The lesions were all confirmed by operation and clinical follow up.Echo-planar difffusion-weighted imaging (DWI)was performed with different b values (0,500,and 1,000s?mm~(-2)),and the apparent diffusion coefficients (ADCs)were measured.Results Malignant and benign tumors had different characteristics in DWI with different b values.With the increase of b value,the signal intensity of tumor/spinal cord ratio decreased quickly in DWI in benign tumors,while the signal intensity of tumor/spinal cord ratio remained similar in DWI in malignant tumors.The mean ADC value of'malignant tumors[(0.78?0.24)?10~(-3)mm~2? s~(-1)] was significantly lower than that of benign tumors [(1.48?+0.20)?10~(-3)mm~2?s~(-1)] (t = 8.9,P

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.
