This study compares and analyzes the similarities and differences between National Health Strategy in America and Healthy China 2030 from three aspects, namely the strategic goals, the main contents, and the leading health indicators.Considering China's social and economic environment, this paper proposes the following suggestions: 1) to emphasize the relevance, dynamics and continuity of health strategy;2) to focus on key population on the basis of full coverage;3) to identify the focus of each phase of implementation;and 4) to highly think of the establishment of systems, including information system, operational supervision system and evaluation index system, etc.These suggestions are meant to provide inspiration to the introduction and further development of the China's national health strategy.

To study the effect of sodium aescinate in inducing human breast cancer MCF-7 cells apoptosis and its possible mechanism. MTT assay was used to detect the inhibitory effect of sodium aescinate on the proliferation of MCF-7 cells. The morphological changes were observed under inverted microscope. DAPI nuclear staining was used to detect the changes in cell nucleus. Annexin V-FITC/PI flow cytometry was adopted to test the apoptosis rate. Changes in apoptosis-related proteins (PARP, cleaved caspase-8 and pro-caspase-3), cell survival-associated signal molecules (AKT and ERK) and their common upstream kinase SRC was detected by Western blotting. The result showed that after different concentrations of sodium aescinate were used to treat breast cancer MCF-7 cells, they inhibited the proliferation of MCF-7 cells in a dose-dependent manner, induced cell apoptosis (typical morphological changes in nucleus, significant increase in cell apoptosis rate). The expressions of cleaved PARP and caspase-8 increased, while the expression of pro-caspase-3 decreased, which further verified sodium aescinate's effect in inducing cell apoptosis. Sodium aescinate significantly inhibited the phosphorylation of cell survival-related signal molecules (AKT, ERK) and down-regulate the activation of their common up-stream kinase SRC. The findings indicated that sodium aescinate can block signals transiting to downstream molecules AKT, ERK, inhibit the proliferation of breast cancer cell MCF-7 cell apoptosis and induced cell apoptosis by suppressing the activation of SRC.

The kinetics of nicotine degradation by O.intermedium DN2 and its application in tobacco waste were investigated. The results showed that the optimum temperature of nicotine degradation by O.intermedium was 30 ℃, the pH value was 6.5 and a mount of inoculum was 5 %. Under above conditions, the kinetics of nicotine degradation of initial concentration 500 mg/L was studied. The results indicated that the degradation process of nicotine with no-induced strain DN2 followed inverse S-shaped curve, and degradation process of nicotine with induced cells of DN2 followed Eckenfelder mode. The half life of nicotine degradation was 17.43 h and 4.10 h, respectively. And the results also showed that tolerance of O.intermedium DN2 to nicotine was up to 5000 mg/L when 0.1 % of glucose was added. Nicotine (2 220 mg/L) in extract of tobacco wastes degraded about 95.22 % by strain DN2 in 60 h incubation, indicating that strain DN2 was of application value in treatment nicotine pollution.

Background and purpose:The occurrence and development of lung cancer are closely correlated with the immune function in the human body.The patients with malignant tumors have shown a disorder of immune function,especially in terms of loss of cellular immune function.The purpose of this study was to investigate the possible auxiliary effect of sipulin in the treatment of advanced non-small-cell lung cancer(NSCLC).methods: Ninety-three patients were randomly divided into two groups:sipulin group:sipulin plus docetaxel+cisplatin;control group:only administered docetaxel+cisplatin.The leukocyte,haemoglobin and platelet,toxicity of digestive tract,body weight,Karnofsky status and efficacy of those patients were evaluated before and after therapy,respectively.Results: Overall response rates were 46.67% and 30.23%(P=0.023)in sipulin group and control group,respectively.The median survival time was 10.1months versus 8.3 months(P=0.035)in sipulin group and control group,respectively.The 1-year survival rate for sipulin group and control group was 52.9% versus 39.4%(P=0.038),respectively.The clinical efficacy and the frequence of leukocyte reduction were better in sipulin group than in control group,the quality of life and clinical symptom of the patients in sipulin group were improved more significantly than those in control group (P

To systematically summarize the evidence on the effectiveness of measures regarding tobacco control in China. Papers on several databases published between 1990 and 2009were systematically searched. Methods in American Guide to Community Preventive Services were used to evaluate the quality and strength of evidence on the effectiveness of tobacco control programs.Overall, 282 studies were included in this paper, but only 75 (26.41%) studies had acceptable execution quality. Items as pharmaceutical therapy and behavior intervention in the smoking population that would show sufficient evidence on the effectiveness of the programs. In general population, multi-component intervention programs appeared to be effective. However, the effectiveness regarding items as clinical consultation, therapy with traditional Chinese medicine,education programs alone, non-smoking related laws and regulations etc. were of insufficient evidence. The overall execution quality of intervention studies on tobacco control in China was considered to be poor and few of them would show the evidence on the effectiveness of the programs. Only few studies on non-smoking related laws and regulations touched upon the positive effectiveness on this issue. We suggested that the execution and evaluation on non-smoking related laws and regulations be strengthened.

Objective To compare the value of conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound in the display capacity of periampullary carcinoma and its relationship with the surrounding tissue.Methods A total of 18 patients with the periampullary carcinoma were diagnosed pathologically or by endoscopic biopsy.Each patient had three imaging modalities by conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound.The display capacity and the relationship between the mass and surrounding tissue were compared with three modalities.Results The display rates of limpid visibilities of carcinoma on conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound were 16.7%(3/18),22.2%(4/18) and 94.4%(17/18),respectively;The display rates of duodenum protrusion on three modalities were 0(0/18),38.9% (7/18) and 72.2% (13/18),respectively,with significant differences among conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound.The double-contrast enhanced ultrasound showed two cases of peripheral vascular invasion and one case of intrahepatic metastasis.Conclusion The double-contrast enhanced ultrasound can increase the display capacity of periampullary carcinoma as a new diagnostic modality for periampullary carcinoma.

OBJECTIVETo study the protective effects of polysaccharide of Spirulina platensis and Sargassum thunbeergii on vascular of alloxan (ALX) induced diabetic rats.
METHODWith the doses of polysaccharide of Spirulina platensis (PSP) and Sargassum thunbeergii (PST) compound (1:1) 12.261, 36.783, 110.349 mg x kg(-1) by i.g. administration to alloxan induced diabetic rats respectively for 6 weeks. Then the blood glucose and the TC, HDL-C, TG, NO, ET in serum were detected. The contraction and relaxation response to NE and ACh in aortic rings of the alloxan induced diabetic rats has been studied.
RESULTThe results showed the compound of PSP and PST could decrease the blood glucose and the TC, TG, NO, ET in serum and increase HDL-C than in the alloxan induced diabetic rats. The contraction responses to NE in aortic rings of the alloxan induced diabetic rats were significantly elevated in the normal rats, and the responses to ACh were significantly lower. PSP and PST compound could significantly lower the responses to NE and significantly elevate the responses to ACh in aortic rings of the alloxan induced diabetic rats.
CONCLUSIONPSP and PST compound could decrease blood glucose and could protect the vascular of alloxan induced diabetic rats.
