Background and purpose:The cortical actin-binding protein,cortactin,participates in several functions in the cytoskeleton system,cellular signal transduction and cell adhesion.There is also increasing evidence that it regulates tumor invasion and metastasis.However,the role played by cortactin in laryngeal carcinoma has not been clearly delineated.The purpose of this experiment was to investigate the effect of silencing cortactin expression on the proliferation and invasion in the human laryngeal carcinoma cell line Hep-2.Methods:A plasmid from a siRNA targeting cortactin was constructed and transfected into a Hep-2 cell line.The siRNA interference efficiency of cortactin was determined by Western blot.The proliferation was measured by MTT assay and plate colony formation. The Transwell test was used to detect the migration and invasion ability of the Hep-2 cells.Empty plasmid-transfected Hep-2 and normal Hep-2 were used as control groups.Results:Compared to Hep-2 cells,the cortactin expression of pSilencer3.1-cortactin-siRNA/Hep-2 was 11.22%(P

Objective To assess the clinical therapeutic effects and safety of Jiangtang Shuxin decoction (JTSXD) on diabetic patients complicated with chronic heart failure (CHF),and to search for its possible function mechanisms.Methods A prospective randomized controlled study was conducted,80 diabetic patients complicated with CHF [New York Heart Association (NYHA) functional class Ⅱ-Ⅲ] admitted into the Department of Traditional Chinese Medicine (TCM) or of Cardiology in Affiliated Hospital of Guangxi Youjiang National Medical College from October 2015 to September 2016 were enrolled,they were assigned to an observation group and a control group by randomized method with a computer,and finally 77 patients (39 cases in observation group and 38 cases in control group) completed this trial.The patients in control group received standardized routine western medical treatment,while the observation group was additionally administered JTSXD (including ingredients:astragalus 15 g,ginseng 10 g,radix ophiopogonis 15 g,radix rehmanniae 15 g,comus 10 g,rhizome coptidis 8 g,peach kernel 10 g,salvia mitiorrhiza 10 g,magnoliaceae 10 g,yam 15 g) on the basis of conventional therapy.The therapeutic course for all the patients in both groups was 2 months.Before and after treatment,the 6-minute walking distance (6MWD) was assessed;the TCM syndrome accumulated scores of the two groups were calculated;the left ventricular end-diastolic volume (LVEDV),the left ventricle ejection fraction (LVEF),the stroke volume (SV),the cardiac output (CO),and the maximum blood flow velocity of early diastolic/atrium late diastolic (E/A) were detected by echocardiography.The serum levels of glycosylated hemoglobin (HbA1c),angiotensin Ⅱ (Ang Ⅱ) and plasma B type brain natriuretic peptide (BNP) were tested with enzyme linked immunosorbent assay (ELISA);the level changes of total cholesterol (TC),triglyeride (TG),high density lipoprotein cholesteral (HDL-C) and low density lipoprotein cholesteral (LDL-C) were observed.Results Compared with the control group,after treatment in the observed group,the TCM syndrome score of palpitation,fatigue and thetotal accumulated score were all obviously decreased (palpitation score:0.9 ± 0.4 vs.1.2 ± 0.8,fatigue score:1.1 ± 0.7 vs.1.7 ± 0.8,total accumulated score:4.8 ± 1.2 vs.8.1 ± 1.8,all P ＜ 0.05);the LVEDV,the serum levels of HbA1c,Ang Ⅱ and BNP were also obviously decreased in the observed group [LVEDV (mL):136.28 ± 17.52 vs.158.82 ± 19.03,HbA1c (％):6.11±0.36 vs.6.89 ±0.32,Ang Ⅱ (ng/L):66.48 ± 17.64 vs.84.55 ± 20.39,BNP (μg/L):138.45 ± 87.55 vs.219.14±88.83,all P ＜ 0.05];The 6MWD,LVEF,SV,CO and E/A were all increased plainly in the observed group [6MWD (m):470.47 ± 79.66 vs.428.46 ± 88.56,LVEF:0.51 ±0.05 vs.0.46 ± 0.04,SV (mL):55.36 ± 2.88 vs.50.32±2.76,CO (L/min):5.74±0.91 vs.4.92±0.74,E/A:1.18±0.27 vs.0.83±0.28,all P ＜ 0.05].The degrees of decreased levels in TC,TG,LDL-C and the degrees of increased levels of HDL-C in observed group were superior to those of the control group,but there were no statistical significant differences (all P ＞ 0.05).Conclusion JTSXD shows good therapeutic effect and safety for treatment of diabetic patients accompanied by CHF (NYHA functional class Ⅱ-Ⅲ),and its mechanisms may be related to its regulation of glucose (reduction of HbA1c level),correction of lipid metabolism disorders,improvement of myocardial energy supply,inhibition of the activation of renin-angiotensin-aldosterone system (RAAS) and the secretion of BNP.

Construction of medical alliances could help structural adjustment of medical resources, promote the shift of medical and health investment to primary level, improve the overall effectiveness of the medical service system, and better meet the health needs of the people. Guangzhou has established a multi-form and multi-level medical alliance system in accordance with local conditions. According to the distribution characteristics of medical resources in the districts under the jurisdiction of Guangzhou, these districts were divided into areas of controlled development, those of stable development and those of encouraged development. Different strategies were taken for various medical alliances. Advantages of traditional Chinese medicine were given full play in community health management and elderly care services, alliance of traditional Chinese medicine specialists was established to provide residents with continuous medical and health services. An appropriate medical insurance payment system was established to promote the implementation of the hierarchical diagnosis and treatment system. However, there were still such problems as unbalanced distribution of medical resources, insufficient leverage role played by medical insurances, and rooms of improvement in the ability of primary medical services.

The reform of medical insurance payment system could promote the transformation of medical services from price medical care to value medical care, which is very important to promote the construction of medical alliance. The authors discussed the reform of medical insurance payment system to promote the construction of medical alliance, and the order of medical alliance covering medical services and seeking medical treatment.For medical service providers, the reform of medical insurance payment system helped to promote the construction of closer medical alliance, guided the sinking of high-quality resources, helped to form a smooth referral mechanism, and strengthened the supervision and assessment of medical behavior. For the demanders of medical services, the differentiated medical insurance reimbursement proportion policy within the medical alliancewas more conducive to attracting the first consultation at the grass-roots level. At the same time, patients had a wider choice of medical treatment and more freedom of choice. In view of the problems existing in practice, the authors suggested that a variety of medical insurance payment and performance systems with value-based medical care as the core should be implemented to deepen the development of medical alliance, the medical insurance system and municipal subsidies should jointly undertake the salary subsidies for sinking medical personnel, and integrate the grass-roots fragmented health care business with the help of medical insurance payment tools, and promote the coverage expansion of the medical insurance reform of the medical alliance based on policy guidance.

At present, the prevalence rate of diabetes presents a rising tendency. The cardiovascular disease is a major complication of diabetes mellitus and acute coronary syndrome (ACS) is a severe form of coronary heart disease. Compared with non-diabetic patients, the disease situation in diabetic ACS patients is more serious with more contradictory problems and difficulty in treatment. Although percutaneous coronary intervention (PCI) plays a certain role in re-canalization of coronary artery, after PCI the problems the patients with diabetic ACS will face are still serious. traditional Chinese medicine (TCM) recognizes that the etiology and pathogenesis of diabetic ACS are deficiency in Qi and Yin, and accumulation of blood stasis and toxin inside the body. Through clinical observation and retrospective analysis, it is found that using "supplementing Qi and nourishing Yin, activating blood circulation and detoxifying"can interfere with the patients' diabetic ACS and simplify the therapeutic regimen, which is an integrated regulatory treatment with multiple links, multiple pathways and multiple targets, and is a sufficient realization of unique superiority of traditional Chinese medicine by using holistic concept, syndrome differentiation and multiple-link interference for comprehensive prevention and treatment of diabetic ACS.

OBJECTIVE：To investigate the synergistic effect and deficiencies between centralized drug quantity purchase policy and medical insurance reimbursement system ，and to provide feasible suggestion to further improve its synergistic effect. METHODS：The literature analysis method and policy evaluation method were adopted to expounds the direct and indirect synergistic effect between the current centralized drug quantity purchase policy and medical insurance reimbursement system in China，and analyze the existing problems so as to put forward the feasible suggestions. RESULTS & CONCLUSIONS ：The centralized drug quantity purchase policy had a direct impact on the payment mode of medical insurance reimbursement system in technical level ，performance evaluation in effect level and process control in management level. The indirect synergy included ： centralized drug quantity purchase policy could promote the adjustment of drug supply security system to adapt to the reform of medical insurance payment ；it could adjust the pharmaceutical market ，and affect the reform of medical insurance reimbursement system. The disadvantages were as follows ：the varieties of selected drugs was still narrow ，and there was room for further improvement in purchasing scope and medical insurance fee reduction ；“one-size-fits-all”payment standard for unselected drug might weaken pharmaceutical companies ’enthusiasm for generic drug research and development. Therefore ，the next step is to significantly expand the variety and scope of procurement ，and appropriately liberalize the medical insurance payment restrictions for drugs with fewer varieties ；coordinate medical insurance reimbursement policies and procurement programs ，and improve the rationality and perfection of medical insurance payment ；guide the medical institutions to change the concept from “price-based medical treatment ”to“value-based medical treatment ”，take into account the interests of all parties in the market ，so as to form a comprehensive coordination adjustment mechanism of drug price and medical insurance reimbursement system.

OBJECTIVE：To investigate the s ynergy between centralized drug volume-based purchasing （called“volume- based purchasing”for short ）and medical insurance negotiation policy. METHODS ：From the aspects of economic and social benefits ， the synergy of volume-based purchasing and medical insurance negotiation was analyzed by using the methods of literature analysis，policy interpretation and interview. The corresponding suggestions were put forward for the problems of the supply and use of drugs. RESULTS & CONCLUSIONS ：The synergy of volume-based purchasing and medical insurance negotiation in terms of economic benefits include medical insurance fund management optimization to improve fund utilization efficiency improvement ； medical insurance fund payment optimization to reduce transaction cost ；network promotion of medical security information platform to reduce the cost of information exchange. The synergy of volume-based purchasing and medical insurance negotiation in terms of social benefits includes relevant index assessment of drug quality evaluation to improve drug quality evaluation system ； medical service level improvement to form compound medical insurance payment mode under total budget management ；enterprise supervision driven by market to reduce the pressure of government supervision. The relevant departments should continue to strengthen the comprehensive management of medical institutions to reduce the phenomenon of irrational drug use ；strengthen policy convergence ，avoid the poor implementation of medical insurance drug adjustment policy ，so that the policy dividend of volume-based purchasing and medical insurance negotiation can benefit the people more through system reform ，optimal allocation of funds ，etc.

OBJECTIVE In order to analyze the current situation of policy tool allocation in China’s TCM formula granule industry， and provide a theoretical basis for the high-quality development of the industry. METHODS Based on the perspective of policy tools，“ TCM formula granules” was used as the keyword to retrieve the official websites of departments directly under the State Council such as the National Medical Products Administration and the National Administration of Traditional Chinese Medicine， as well as provincial governments. The relevant clauses in the policy documents related to TCM formula granules in China from 1993 to 2022 were encoded， and then the application of policy tools was summarized and classified. RESULTS & CONCLUSIONS A total of 12 national documents and 77 provincial documents were ultimately selected， involving 556 relevant policy clauses. It was found that among the relevant policy tools， environmental policy tools had the highest degree of attention， accounting for 62.6%； the proportions of demand-oriented policy tools and supply-oriented policy tools were less， accounting for 17.8% and 19.6%， respectively. From the perspective of policy tools， the use of demand-oriented policy tools in current policy texts was relatively simple， and various policy tools were given low attention； from the perspective of policy objectives， the proportion of use of environmental， demand-oriented and supply-oriented policy tools were not balanced enough. It is suggested to increase the proportion of demand- oriented policy tools to meet international competition； emphasize the use of supply-oriented policy tools to strictly control product quality； consolidate the use of environmental policy tools to standardize quality standards. On this basis， we will coordinate the overall situation， balance the use of various policy tools and promote the development of TCM formula granule industry.
