Aim To investigate the effects of com-bined treatment of SAHA and TRAIL on human breast cancer ER positive cell line MCF-7 . Methods MCF-7 cells were treated with SAHA and/or TRAIL. The inhibitory rates were detected by real-time cell prolifer-ation assays. Morphology changes of MCF-7 cells were observed through time-lapse live cell imaging acquisi-tion. Results Real-time cell proliferation assays showed that the anti-tumor efficacy of SAHA was sig-nificantly enhanced in combination with TRAIL. The results of time-lapse live cell imaging acquisition dem-onstrated that, with treatment of SAHA and TRAIL, the growth inhibition of MCF-7 cells was more obvious than that of in TRAIL or SAHA treatment alone. Con-clusion The combination treatment of SAHA and TRAIL has a synergistic effect of growth inhibition on breast cancer MCF-7 cells.

Objective To analyze the effects of gentongping pill combined with physiotherapy on the patients with vertebral artery type of cervical spondylosis. Methods 134 patients with vertebral artery type of cervical spondylosis were grouped into two groups, the observation group and the control group. The two groups were treated with physiotherapy and the observation group was treated with Gentongping pill. The effects in the two groups were evaluated. Results The total efficiency in the observation group was higher than that in the control group(P<0.05). After treatment, the symptom score, CASCS score, mean blood flow velocity in left vertebral artery and right vertebral artery, TNF-α and IL-6 level in the observation group were better than those in the control group (all P<0.05). There was no obvious adverse reaction in the two groups. Conclusion Itcan improve the therapeutic effect which Gentongping pill is used on the treatment of patients with vertebral artery type of cervical spondylosis.

The medical equipment benefit evaluation analysis has become an important constituent of cost and medical equipment management. It can not only use the economic benefit index to estimate the service condition of equipment, but also form the comprehensive evaluation system with basic of economic benefit evaluation and auxiliary of science study. Based on comprehensive evaluation result, to search the weakness of equipment utilization and promote the overall development of hospitals and clinics orderly.

Based on the imaging photoplethysmography (iPPG) and blind source separation (BSS) theory the author put forward a method for non-contact heartbeat frequency estimation. Using the recorded video images of the human face in the ambient light with Webcam, we detected the human face through software, separated the detected facial image into three channels RGB components. And then preprocesses i.e. normalization, whitening, etc. were carried out to a certain number of RGB data. After the independent component analysis (ICA)'theory and joint approximate diagonalization of eigenmatrices (JADE) algorithm were applied, we estimated the frequency of heart rate through spectrum analysis. Taking advantage of the consistency of Bland-Altman theory analysis and the commercial Pulse Oximetry Sensor test results, the root mean square error of the algorithm result was calculated as 2. 06 beat/min. It indicated that the algorithm could realize the non-contact measurement of heart rate and lay the foundation for the re- mote and non-contact measurement of multi-parameter physiological measurements.

The multilateral trading system embodied in the World Trade Organization has contributed significantly to economic growth, development and employment throughout the past fifty years. We are determined, particularly in the light of the global economic slowdown, to maintain the process of reform and liberalization of trade policies, thus ensuring that the system plays its full part in promoting recovery, growth, and development. The negotiations on trade in services shall be conducted with a view to promoting the economic growth of all trading partners and the development of developing and least-developed countries. The General Agreement on Trade in Services (GATS) is among the World Trade Organization's most important agreements. The accord, which came into force in January 1995, is the first and only set of multilateral rules covering international trade in services. Ig has been negotiated by the Governments themselves, and it sets the framework within which firms and individuals can operate. The GATS has two part: the framework agreement containing the general rules and disciplines ; and the notional "schedules" which list individual countries' specific commitments on access to their domestic markets by foreign suppliers. Each WTO Member lists in its national schedule those services for which it wishes to guarantee access to foreign suppliers. All commitments apply on a non-discriminatory basis to all other Members. There is complete freedom to choose which services to commit. In addition to the services committed, the schedules limit the degree to which foreign services providers can operate in the market. For example, a country making a commitment to allow foreign banks to operate in its territory may limit the number of banking licenses to be granted (a market access limitation). It might also fix a limit on the number of branches a foreign bank may open (a national treatment limitation). The GATS covers all internationally-traded services with two exception : services provided to the public in the exercise of governmental authority, and , in the air transport sector, traffic rights and all services directly related to the exercise of traffic rights and all services directly related to the exercise of traffic rights. The GATS also defines four ways in which a service can be traded, known as "modes of supply" Services supplied from one country to another (e.g international telephone calls), officially known as "cross-border supply"; Consumers from one country making use of a service in another country(e.g tourism), officially known as "consumption abroad"; A company from ton country setting up subsidiaries or branches to provide services in another country (e.g a bank from one country setting up operations in another country), officially known as "commercial presence" ; and Individuals travelling from their own country to supply services in another (e.g an actress or construction worker), officially known as "movement of natural persons". Trade liberalization, and even economic growth, are not the ends in themselves. The ultimate aim of Government is to promote human welfare in the broadest sense, and trade policy is only one of many instruments Governments use in pursuing this goal. But trade policy is nevertheless very important, both in promoting growth and in preventing conflict. The building of the multilateral trading system over teh past 50 years has been one of the most remarkable achievements of international cooperation in history. The system is certainly imperfect, which is one of the reasons why periodic negotiations are necessary, but the world would be a far poorer and more dangerous place without it. In January 2000, WTO Member Governments started a new round of negotiations to promote the progressive liberalization of trade in services. The GATS agreement specifically states that the negotiations "shall take place with a view to promoting the interests of all participants on a mutually advantageous basis" and "with due respect for national policy objectives and the level of development of individual Members". The pace and extent of these negotiations are set by the WTO's 140 Member Goverments themselves according to their different national policy priorities. Recently, however, the negotiations and the GATS itself have become the subject of ill-informed and hostile criticism. Scare stories are invented and unquestioningly repeated, however implausible. It is claimed for example that the right to maintain public services and the power to enforce health and safty standards are under threat, though both are explicitly safeguarded under the GATS. How have serious people come to believe what is, on the face of it, out of the question? Why should any Government, let alone 140 Governments, agrees to allow themselves to be forced, or force each toher, to surrender of compromise powers which are important to them, and to all of us? Decision-making in open societies presupposes informed public discussion. It must be based on fact rather than fiction. The purpose of this booklet is to contribute to this discussion and to a greater public understanding of the GATS by correcting statements made in some recent publication which we believe are misleading the public and undermining support for international economic cooperation. It must not be assumed that becuase we have disputed some allegations we accept that others are well-founded: these are merely examples.

Objective To investigate the prevalence, characteristics and risk factors of superior vena cava and auxiliary branchs thrombosis in hemodialysis patients with internal jugular venous indwelling catheter. Methods A total of 43 cases on hemodialysis (HD) with indwelling short-term catheter in internal jugular vein from June to December in 2007 were enrolled in this study. The clinical data and biochemical indicators were collected to investigate the prevalence, characteristics and risk factors of venous thrombosis around indwelling catheter, such as, superior vena cava and auxiliary branehs in these patients. Results Short-term double Iumen internal jugular venous catheter were placed in 43 HD patients. Different degrees of central vein thrombosis were found in 21 of the 43 HD patients (48.8%). The ratio of thrombosis in jugular vein, brachiocephalic vein, subclavical vein and uperior vena cava was 100% (21/21), 28.6% (6/21), 23.8%(5/21) and 19.0%(4/21), respectively. Ten of the 21 HD patients (47.6%) with central vein thrombosis presented clinical symptoms. Five cases developed edema of the upper extremity, 2 cases had new-onset symptom's pulmonary embolism, and 3 eases developed blood overflowed from inlet port of circum-catheter. The ratio of diabetes mellitus, malignant tumor, the prevalence of increased level of serum lipoprotein a and plasma homocysteic acid were significantly higher in the HD patients with central vein thrombosis than that in those without central vein thrombosis. The odds ratio of diabetes mellitus, malignant tumor, high serum lipoprotein a and high plasma homocysteic acid was 5.758, 4.750, 6.967 and 8.533, respectively. Conclusions The prevalence of central vein thrombosis in HD patients with short-term indwelling catheter in internal jugular vein is quite high. Its clinical symptom is insidious but dangerous. Diabetes mellitus, malignant tumor, high serum lipoprotein a and high plasma homocysteic acid may be the important risk factors of central vein thrombosis in above HD patients.

Toll-like receptors (TLRs), a large family consisting of at least 10 members, are evolutionarily conserved to recognize pathogen-associated molecular patterns (PAMPs). TLRs activation not only initiates innate immunity, but also regulates enhance antigen-specific acquired immunity, and thus associates innate and adaptive immunity. In recent years, studies on the TLRs signaling, especially their negative regulation, rapidly progressed. TLRs signaling pathway and their roles in regulating immune responses against invading pathogens were reviewed.

The effect of Flavonoids of Gly-cyrrhiza (FG) on ethanol-induced liver injury was studied in mice. Administration of FG to mice prior to ethanol treatment ,either once daily for four days or a single dose, the increase of malondialdehyde and the decrease of reduced glutathione were inhibited dose- dependently.Electron microscopic examination showed that the ethanol-induced damage of hepatocytes could be ameliorated by FG pretreatment. However, no protective effect was observed when FG was administrated to mice after ethanol intoxication.

Objective To investigate the association between serum Klotho and oxidative stress in metabolically healthy obese individuals. Methods 180 physicalexamination subjects were investigated. They were devided into 3 groups:60 cases of normal weight and metabolic normality,60 cases of metabolically healthy but obese( MHO) ,60 cases of obesity with metabolic syndrome. Fasting blood glucose(FBG),2 h blood glucose(2 hBG),triglyceride ( TG) ,high densitylipoprotein cholesterol( HDL-C) , systolic blood pressure, diastolic blood pressure,body height, body weight,waist circumference,body mass index( BMI) were recorded. Malondialdehyde( MDA) ,superoxide dis-mutase( SOD) ,total antioxidation capacity( TAOC) ,Klotho were detected by ELISA. The difference of clinical pa-rameters,metabolic parameters,oxidative stress and Klotho among these three groups was compared by the methods of covariance analysis. Regression analysis and pearson correlation were used to evaluate the relationship of Klotho with oxidative stress. Results Compared with the control group, TAOC, SOD, Klotho were decreased significantly while MDA elevated significantly in both MHO group and obesity with metabolic syndrome group(P<0. 05). Com-pared with MHO group, TAOC, Klotho were significantly lower in obesity with metabolic syndrome ( P<0. 05 ) . Klotho protein was significantly positively associated with SOD, TAOC, negatively associated with waist circumfer-ence,BMI,FBG,2 hBG(r= -0. 182,-0. 225,-0. 221,-0. 202,-0. 188,P<0. 05). SOD,TAOC were deter-minants for Klotho. Conclusion The balancebetween oxidative and antioxidative system is disturbed in subjects with MHO. Klotho protein may maintain the normal metabolism of thebody by regulating the oxidative stress.
