1.Effects of combination treatment with SAHA and TRAIL on ER positive breast cancer cell MCF-7
Chinese Pharmacological Bulletin 2016;(2):223-228
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.
2.Clinical research on the effect of gentongping pill combined with physiotherapy on the patients with vertebral artery type of cervical spondylosis
Chinese Journal of Biochemical Pharmaceutics 2017;37(8):42-44
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.

4.Non-contact heart rate estimation based on joint approximate diagonalization of eigenmatrices algorithm.
Journal of Biomedical Engineering 2014;31(4):729-733
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.

5.WTO DDA and Negotiations on Healthcare Servics.
Journal of the Korean Medical Association 2002;45(9):1080-1089
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.

6.Strategies for novel protein biomarker identification through multiple reaction monitoring mass spectrometry
Chinese Journal of Laboratory Medicine 2011;34(6):484-488
With the development of proteomic technologies, large numbers of putative biomarkers have been screened out but few of them are put into the clinical application.Recently, MRM-MS based approaches and strategies have aroused extensive concern in domestic and overseas clinical laboratory community because of their cost-efficiency, time-saving, high analytical sensitivity and accuracy.MRM-MS based approaches, especially SISCAPA, may gradually become a key technology for the protein biomarker research in the near future.In this review, the bottleneck existing in the field of protein biomarkers research, and features as well as applications of MRM-MS are discussed and the future trend of research is prospected.

Chinese Journal of Postgraduates of Medicine 2012;35(10):13-14
ObjectiveTo study the change of serum interferon- γ(IFN- γ ) and interleukin-4(IL-4)level in children suffered from cough variant asthma after montelukast combined with loratadine therapy.MethodsForty-six patients of children cough variant asthma were recruited and accepted montelukast combined with loratadine therapy for 8 weeks.The changes of serum IFN-γ and IL-4 before and after therapy were compared.ResultsCompared with before therapy,the level of serum IFN- γwas decreased [ (59.94 ± 9.43) ng/L vs.(39.94 ± 9.07) ng/L ] and IL-4 was increased[ ( 48.78 ± 22.23 ) ng/L vs.(60.78 ±16.48) ng/L] after therapy,there were significant differences (P <0.05).ConclusionMontelukast combined with loratadine in the treatment of children cough variant asthma can improve the balance of IFN- γ/IL-4,which deserve further study.
8.Recent progress in the improvement of the coupling efficiency of "difficult sequences" in peptide synthesis
Acta Pharmaceutica Sinica 2007;42(2):111-117
Even though chemistry is now in place that potentially allows high coupling efficiencies to be attained, successful coupling is usually a challenge when so-called "difficult sequences" is encountered in peptide synthesis. Some factors that affect the coupling efficiency have been discussed and related methods to overcome those obstacles have been introduced in present review. All suggestions proposed here are valuable and also feasible to improve the coupling completeness in both liquid-phase or solid-phase peptide synthesis.
9.The correlational study between the depression after acute stroke and nerve function defect
Chinese Journal of Primary Medicine and Pharmacy 2014;21(2):174-176
Objective To explore the correlation between the depression status of patients with post-stroke depression(PSD) and nerve function defect.Methods 75 patients in the first 24h of acute stroke onset were selected.According to the Zung depression self rating scale(SDS),75 cases were divided into simple stroke patients group and PSD group,and the Hamilton depression scale (HAMD) and Scandinavian nerve function defect rating scale (SSS) were used for further evaluation.The score results were statistically analyzed.Results Of 75 cases with acute stroke,32 cases(42.7%) were diagnosed PSD.Admission day 2,at the end of 1,2 and 3 weeks,the HAMD scores between PSD patients and simple acute stroke group had statistically significant differences (all P < 0.01).The HAMD scores of three groups of PSD patients (light,medium,heavy) appeared obvious changes with the prolonged time,which were significantly higher than the simple stroke group.The SSS score of simple stroke group and mild PSD patients increased with prolonged observation time,the difference between the two groups was significant (q =9.75,P < 0.05).The SSS score of moderate and severe PSD patients decreased with prolonged observation time,compared with the simple stroke group,the differences were statistically significant(q =50.23,46.82,all P < 0.05).In simple stroke patients and mild PSD patients,HAMD scores and SSS score had no correlation (r =0.062,P > 0.05).In moderate and severe PSD patients,HAMD score and SSS score had correlation (r =4.682,P < 0.05).Conclusion The incidence rate of PSD in acute brain stroke patients was 42.7%,and in patients with moderate and severe PSD,HAMD scores correlated with the degree of nerve function defect.Early intervention on depression treatment and promote the recovery of neural function is also important.
10.Requirement of diagnosis and tereatment for liver diseases and improvement of laboratory technology
Chinese Journal of Laboratory Medicine 2012;35(2):126-130
There are so many patients with different liver diseases in our country that the diagnosis and treatment of liver diseases directly relate to the people's healthy level.The requirement of diagnosis and treatment to clinical laboratories can be summarized as: ( 1 ) sensitivity,which means shortening window period;(2) specificity,which means various subtypes and variant can be detected;( 3 )speed,which means finding out the pathogen as soon as possible;(4)accuracy,which means providing physicians with accurate test reports.Detecting techniques,for instances,chemiluminescence,polymerase chain reaction and gene mutational site detecting method,were applied to the diagnosis and treatment of liver disease,thus improving the degree of precision,accuracy,sensitivity,specificity and detection speed and satisfying the requirement of diagnosis and treatment maximatily.
