Objective:The aim of the present study was to conduct an international comparison of the high-val-ue drugs payment systems of some selected countries, and introduce them to the Chinese context. Australia, America and Germany's high-value drugs payment systems were selected to serve as references for China. Methods: The main content and characteristics of three countries' payment systems were analyzed in four aspects:expenditure copayment mode, paid-scope selection, drug price negotiation, and drug rational use management which were then compared with the Chinese status. Results:Through the difference in healthcare system tradition, the above countries have vari-ous copayment mode, but they all select paid-drug by cost-effectiveness analysis with corresponding control measures. Conclusions:China should: establish a co-payment mode for the high-value drugs on the basis of a critical illness medical insurance found;build a national pharmaco-economic evaluation index system and improve the national nego-tiation superiority, while emphasizing on risk-sharing mechanism; and make series specifications to guarantee the drug to be rationally used.

Objective To investigate the effects of HMME mediated photodynamic therapy (PDT) on apoptosis of murine hepatoma cell line MM45T-Li.MethodsThe photodynamic treatment on MM45T-Li cells was performed in vitro using HMME as photosensitizer and 630 nm laser as light source.The ceils were incubated with HMME of 2.5,5,10 and 20 μg/ml for 4 h respectively,and then irradiated with laser at different dosages.The dark toxicity of HMME and the activity of cells after PDT were evaluated by MTT assay.The effect of PDT on apoptosis were observed by Hoechst fluorescent staining analysis.ResultsMTT assay showed that there were no significant effects on cell growth in each concentration group of HMME when the cells were not exposed to light.The inhibition ratio of cells increased with laser dosage at HMME concentration of 10 and 20 μg/ml.Chromatin condensation,nuclear pyknosis and karyorrhexis were observed after PDT by Hoechst fluorescent staining analysis.The apoptosis rate increased in groups of 5.4 J/cm2 and 7.2 J/cm2 compared with that of control (P＜0.05).Conclusion HMME mediated PDT can efficiently induce the apoptosis of MM45T-Li cells.

Objective To investigate and compare the killing effect of photodynamic therapy (PDT)induced by hematoporphyrin derivative (HpD),hematoporphyrin monomethyl ether (HMME) and photocarcinorin (PsD007) on human leukemia cells K562 in vitro.Methods Human leukemia cells were cultured with serial concentrations of photosensitizers followed by irradiation of different dosage of laser light,then MTT colorimetric assay was applied to measure the relative survival rate of PDT for the cells.Results Significant difference in the inhibitory between the PDT group and control group was observed (P＜0.05).The survival rate of PDT for the cells elevated along with the increase in the concentration of sensitizer and dose of laser light.When the photosensitizer concentration was bigger (25 μg/ml) or the energy density was bigger (7.2 J/cm2),the effect of PsD007 was better than HMME,and they were significantly better than HpD (P＜0.05).Conclusion PDT has significant killing effect on human leukemia cells K562,and its relative inhibitory rate appears to be correlated with the dose of sensitizer and laser light irritation.The effect of PDT is related to the photosensitizers.The effect of HpD-PDT is not as effective as PsD007 and HMME.On the conditions of higher energy density and larger photosensitizer concentration,the effect of PsD007-PDT is better than HMME-PDT.

OBJECTIVE:To evaluate the affordability of 3 anti-tumor targeted drugs gefitinib,trastuzumab and sunitinib in ur-ban and rural residents of Hubei province,and to provide reference for medical insurance price admission of anti-malignant tumor targeted drugs in China. METHODS:Referring to the incidence of malignant tumor stated in statistical yearbook of Hubei province and income data of urban and rural residents in Hubei province,based on the policy of reducing the price of imported drugs by 50% mentioned in the national drug price negotiations,and assume the drugs are included in the medical insurance reimbursement list,WHO/HAI standard survey method,catastrophic expenditure evaluation method and poverty effect evaluation method were ad-opted to calculate the affordability of 3 drugs. RESULTS:According to WHO/HAI standard survey method,increment of payment for 3 drugs were 64.00%-74.00% before and after 50% discount and reimbursement. According to catastrophic expenditure evalua-tion method,50% discount of gefitinib and reimbursement gefitinib,trastuzumab and sunitinib in urban area would result in cata-strophic expenditures of 20.00%、59.28% and 35.48% patients;in rural area,would result in catastrophic expenditures of 50.63%、74.72% and 75.93% patients. According to poverty effect evaluation method,50% discount of 3 drugs and reimbursement caused less than 31.95% urban and rural patients falling to poverty. CONCLUSIONS:Fifty percentage discount of 3 anti-tumor targeted drugs mentioned in the national drug price negotiations cause the economic burden more serious for rural residents than urban resi-dents. In the formulation of policies,the corresponding reimbursement ratio should be adjusted according to urban and rural areas, drug price and disease types for a balance of patients with different economic burden.

Objective: To analyze the New Cooperative Medical System ( NCMS ) funds and Individual afford-ability of anti-tumor targeted drugs under different medical insurance entry price, and to provide the basis for establis-hing the access price for medical insurance. Methods: Choosing Conmana or Kemer ( the lung cancer targeted drug) and Herceptin (breast cancer targeted drug) to analyze the Wuhan NRCMS operating status from 2012 to 2014, use tumor surveillance data from Hubei Province during the period from 2011 to 2015;consult clinical experts to form expert consensus price, refer to the Jiangsu Province Access Price and National Negotiation Price, and explore the fund bal-ance and individual affordability when the afore-mentioned two kinds of drugs can be compensated by medical insurance under different price. Results:The basic account balances of NRCMS in Wuhan from 2016 to 2018 are-11. 948 million Yuan, 2. 513 million Yuan and 82. 955 million Yuan when Kemer can be compensated by medical insurance under Na-tional Negotiation Price. Taking the compensation of Herceptin under National Price after the bargaining, the basic ac-count balances are -26. 901 million Yuan,-35. 962 million Yuan and 17. 542 million Yuan respectively. The rate of poverty caused by illness falls to 33. 40% from 45. 85% when Conmana can be compensated by Medical Insurance un-der National Negotiation Price, while this rate falls to 45. 42% from 46. 00% for Herceptin. Conclusion:The two kinds of drugs can be afforded by the Wuhan NRCMS after the medical insurance access price is negotiated by the govern-ment, but the individual affordability of Herceptin at the National Negotiation Price is worse.

OBJECTIVE:To provide reference for promoting the rational use of essential drugs in primary medical institutions. METHODS:Twenty-three rural primary medical institutions(8 township health centers,15 village clinics)were randomly selected from 2 poverty-stricken counties in Chongzuo city of Guangxi Zhuang Autonomous Region. The utilization of essential drugs was investigated and analyzed statistically through exporting hospital information system data and on-site interviews. RESULTS:The utilization rate of essential drugs in sample township health centers was 72.4％,and the amount of essential drugs accounted for 78.3％. The utilization rate of variety from National List of Essential Drug was 36.9％,which in the Autonomous Regions Essential Drug List Supplement was 47.2％(utilization rate of chemical drugs was 53.9％,and that of Chinese patent drugs was 39.7％). The utilization rate of essential drugs in sample village clinics was 64.4％;utilization rate of variety from National List of Essential Drug was 18.3％, which in the Autonomous Regions Essential Drug List Supplement was 10.5％. The amount of 5 major categories accounted for 47.9％ of total amount of chemical agents,among which that of antimicrobial agents took up the highest proportion,being 35.9％. Among top 10 drugs in the list of amount,there were 8 national essential drugs and 4 antimicrobial agents. There were 2.90 kinds of drugs in each outpatient prescription averagely in sample township health centers;the average proportion of antibiotic prescription was 43.0％;the cost of each prescription was 33.12 yuan in average. CONCLUSIONS:The utilization rate of essential drugs in primary medical institutions is lower than the requirements of policy. There are great difference in utilization rate between chemical agents and Chinese patent drugs of township hospital in Autonomous Regions Essential Drug List Supplement. The cost proportion of antimicrobial agents is high. The rationality of prescription drug use still needs to be improved. It is suggested to guarantee essential drugs supply,adjust Autonomous Regions Essential Drug List Supplement in time,control the price of main categories and strengthen antimicrobial agent use monitoring so as to further promote rational drug use.

OBJECTIVE:To provide reference for promoting the rational use of essential medicines in primary medical institutions.METHODS:Twenty six rural primary medical institutions (13 township health centers,13 village clinics) were randomly selected from 2 poverty-stricken county (city) in Huanggang city of Hubei province.The utilization of essential medicine was investigated and analyzed statistically through exporting hospital information system data and on-site interviews.RESULTS:The utilization rate of essential medicine in sample township health centers was 76.9％,and the amount of essential medicine accounted for 93.0％;the utilization rate of essential medicine in sample village clinics was 89.7％.The utilization rate of variety from essential medicine list was 53.6％ in sample township health centers and 25.0％ in sample village clinics;the utilization rate of variety from National Essential Medicine List was higher than that of Provincial Essential Medicine List Supplement.The amount of 5 major categories as antimicrobial agents,cardiovascular agent in sample primary medical institutions accounted for 64.7％ of chemical agents.The top ten medicines in the list of amount were all essential medicine,9 of which were national essential medicines.There were 2.8 kinds of medicines in each outpatient prescription averagely in sample township health centers.The proportion of antibiotic prescription was 44.2％.CONCLUSIONS:The utilization rate of essential medicines in township health centers of this area is lower than WHO recommended value,and the ratio of amount meets the policy requirements.The utilization rate of variety from Provincial Essential Medicine List Supplement is in low level in primary medical institutions;the amount of anti-microbial drugs is in high level;the rationality of medicine use in prescriptions needs to be improved.It is suggested to adjust the type of provincial supplement list dynamically according to actual situation and control the price and amount of main categories strictly,the rationality of prescription.

Most of the CHD patients reveal string pulse, mainly due to damage of heart function, lowering of arterial compliance and increase of total peripheral resistance. The common pulse in patients of blood diseases reveal frequent, tiny, string and slippery characteristic, mostly due to the increase of compensatory pumping action of the heart, shortening of ejection time of the left heart, with better vessel compliance and hemorheology, low total peripheral resistance.

Esophageal leiomyoma is the most common benign tumor of the esophagus,usually asymptomatic.With the development and widespread application of endoscopic ultrasonography technology,its detection rate has been increasing year by year.Its diagnostic methods have evolved from initial esophagography and chest electronic computed tomography,to endoscopic ultrasonography,endoscopic ultrasonography-guided fine-needle aspiration,and endoscopic ultrasonography-guided fine-needle biopsy.The technology is constantly updated,and the diagnostic accuracy is constantly improving.The treatment methods have also shifted from previous open chest surgery to thoracoscopic surgery,and in recent years,there has been a shift towards ultra minimally invasive techniques such as endoscopic mucosal resection,endoscopic submucosal dissection,endoscopic submucosal excavation,endoscopic full-thickness resection,and submucosal tunnel endoscopic resection.This article provides a review of the diagnosis and endoscopic treatment progress of esophageal leiomyoma.

Background:At present,the detection rate of esophageal leiomyoma is increasing year by year,among which giant esophageal leiomyoma(GEL)can be caused by secondary compression,malignant and even death.The safety and effectiveness of submucosal tunnel endoscopic resection(STER)in the treatment of GEL need to be further verified.Aims:To assess the safety and efficacy of STER in the treatment of GEL.Methods:Fifteen patients who underwent endoscopic ultrasound and STER surgery from June 2020 to June 2023 at General Hospital of Xinjiang Military Region,and postoperative pathological biopsy confirmed GEL to assess the efficacy,complications,tumor recurrence and follow-up.Results:In 15 patients with GEL,8 were male and 7 female;GEL was completely resected and the margin was clean;the maximum tumor diameter was 8.5 cm;mean operation time of 52 minutes;fewer adverse events and no delayed bleeding;all underwent conservative treatment;mean hospital stay of 6 days;and no discomfort and recurrence in the postoperative follow-up.Conclusions:STER is safe and effective in the treatment of GEL.
