摘要:OBJECTIVE:To evaluate the price and affordability of rare disease drugs in China and provide the suggestions for the improvement of rare disease drug affordability in order to provide reference for the relevant decision-making of government departments. METHODS :According to the List of the First Batch of Rare Diseasesand Diagnosis and Treatment Guideline for Rare Diseases(2019 edition),rare disease drugs were selected. The median price ratio (MPR)was used to evaluate the drug price level , and the ratio of the annual drug costs to the annual disposable income of urban or rural residents was used to evaluate the affordability,and the impact of price management policieson drug prices and affordability. RESULTS and CONCLUSIONS :A total of 71 kinds of rare disease drugs were included ,and the median MPR of them was 0.83;among them ,the median MPR of the original drugs was 1.13,and the median MPR of the generic drugs was 0.37. The annual cost of 71 rare disease drugs was 0.001-178.43 times the average annual income of urban residents ,and 0.003-456.57 times the average annual income of rural residents. There were 21 and 28 drugs whose annual cost exceeded the annual income of urban and rural residents.After the implementation of national medical insurance negotiation or volume based procurement of 14 drugs,the median MPR of these drugs decreased from 1.71 to 0.46. For urban residents ,the number of unaffordable drugs had been reduced from 8 to 0;for rural residents,it had been reduced from 10 to 5. In summary ,the price level of orphan drugs in China was slightly lower than international reference price ,but the price level of original drugs was higher than the international reference price ,and the cost of some drugs far exceeded the residents ’ability to pay. It is suggested that the government should strengthen the price management of original drugs ,promote the substitution of high-quality generic drugs for original drugs ,and improve the payment system for high-value rare disease drugs.

RESULTS :The linear range of gallic acid ,ellagic acid ,1,6-di-O-galloyl-β-D-glucose,1,2, 6-tri-O-galloyl-β-D-glucose and 1,2,3,6-tetra-O-galloyl-β-D-glucose were 0.989-63.3,1.58-101,1.01-64.7,3.31-212,3.34-214 μg/mL (r≥0.997 3),respectively. RSDs of precision ,reproducibility and stability tests (12 h)were all lower than 3.2%. The average recoveries of the 5 components were 103.2%(RSD=4.85%),99.1%(RSD=2.80%),101.5%(RSD=1.31%),102.9%(RSD= 2.73%)and 104.7%(RSD=1.28%),respectively. The average contents of the above components in the branch of J. mandshurica were 0.296 5,0.621 1,0.562 5,3.111 7 and 3.451 3 mg/g,respectively. The average contents of above components in the root were 0.673 4,2.755 5,0.964 0,2.946 6 and 4.836 4 mg/g,respectively. The total contents of the 5 components in the branch and roo t of J. mandshurica were 8.043 2 and 12.175 9 mg/g,respectively. The contents of gallic acid ,ellagic acid and 1,6-di-O-galloyl- β-D-glucose in roots were significantly higher than those in branches (P<0.05 or P<0.01). There were no significant differences in the contents of the other 2 components and the total contents of the 5 components in branches and roots (P>0.05). The cumulative interpretability (R 2X,R 2Y) and cumulative predictability (Q 2) of the model established by PLS-DA were 0.943,0.745,and 0.710 respectively. The model load diagram showed that the distance between the ellagic acid and the origin was the farthest ,and only variable projection importance of the content of the ellagic acid was greater than 1. CONCLUSIONS:The established method can be used for the content determination of 5 components in the branch and root of J. mandshurica . Except for 1,2,6-tri-O-galloyl-β-D-glucose,the contents of other 4 components and total contents of the 5 components in the root of J. mandshurica are higher than those of the branch. Ellagic acid is selected as the potential marker for discriminating the branch and root samples.

METHODS :Human cutaneous squamous cell carcinoma SCL- 1 cells were divided into blank control group (0.1% DMSO) and ST different concentration groups (5,10,20 μmol/L). CCK- 8 assay,5-ethynyl-2′-deoxyuridine(EDU)test, scratch test and Transwell chamber invasion test were adopted to test the proliferation ,migration and invasion ability. The expression of N-cadherin and E-cadherin were detected by Western blot and immunofluorescence assay . Other SCL- 1 cells were collected and divided into blank control group (0.1% DMSO),ST group (20 μmol/L),ST+NSC228155 group [ 20 μmol/L ST+100 μmol/L NSC228155(EGFR agonist )] and ST+SC 79 group [ 20 μmol/L ST+20 μmol/L SC79(PI3K/Akt agonist )]. The proliferation ,migration and invasion ability of SCL- 1 cells in each group were detected by CCK- 8 assay,scratch test and Transwell chamber invasion assay. The expression of epidermal growth factor receptor (EGFR),phosphatidylinositol 3 kinase(PI3K),phosphorylated phosphatidylinositol 3 kinase(p-PI3k),protein kinase B (Akt)and phosphorylated protein Akt (p-Akt)protein of cells in blank control group and ST different concentration groups(5,10,20 μmol/L)were determined by Western blot assay so as to validate the relationship between ST effect and EGFR/ PI3K/Akt signaling pathway. SCL- 1 cells and human normal skin fibroblasts cell WS 1 were divided into blank control group (0.1% DMSO),ST group (20 μmol//L),ZD1839 group(positive control ,20 μmol//L,EGFR inhibitor )and LY 294002 group(positive control,20 μmol//L,PI3K/Akt inhibitor ). CCK- 8 assay was used to detect the cell proliferation in order to evaluate the cells cytotoxicity of ST. RESULTS :Compared with blank control group ,the proliferation ,migration and invasion ability of SCL- 1 cells were significantly decreased in 5,10,20 μmol/L ST groups(P<0.05). Western blot and immunofluorescence assay showed that the expression of N-cadherin in SCL- 1 cells were decreased significantly in 5,10,20 μmol/L ST groups(P<0.05),while the protein expression of E-cadherin was increased significantly (P<0.05);the protein expressions of EGFR ,p-PI3K and p-Akt were significantly decreased (P<0.05). Compared with ST group ,the proliferation ,migration and invasion ability of SCL- 1 cells were increased significantly in ST + NSC 228155 group and ST + SC 79 group (P<0.05). Compared with blank control group ,the proliferation ability of WS 1 cells had no significant change in ST group ,while the proliferation ability of SCL- 1 cells was decreased significantly (P<0.05);the proliferation ability of the two kinds of cells were decreased significantly in ZD 1839 group and LY 294002 group(P<0.05). Compared with ST group ,the proliferation ability of WS 1 cells was decreased significantly in ZD1839 group and LY 294002 group(P<0.05),but there was no significant difference in the proliferation ability of SCL- 1 cells (P>0.05). CONCLUSIONS :ST may inhibit the proliferation ,EMT and metastasis of SCL- 1 cells through inhibiting the activation of EGFR/PI 3K/Akt signaling pathway ,and its side effects are few.

摘要:OBJECTIVE:To evaluate the cost-utility of the pan-genotypic direct-acting antivirals (DAAs)in the treatment of patients with chronic hepatitis C infection ,and to provide pharmacoeconomic evidence for relevant health care decisions. METHODS:A Markov model was established from a societal perspective with newly diagnosed chronic hepatitis C patients in China as the target population ,and analyzed quality-adjusted life years (QALYs)and incremental cost-utility ratios (ICERs)of patients with chronic hepatitis C with sofosbuvir/velpatasvir ,glecaprevir/pibrentasvir,sofosbuvir+coblopasvir. Sensitivity analysis was used to verity the robustness of the results. RESULTS :Glecaprevir/pibrentasvir increased QALYs by 0.002 1 and costs by 25 021 RMB,compared to sofosbuvir/velpatasvir ;its ICERs was 12 129 031 yuan/QALY(willingness to pay threshold was 70 892 yuan/QALY),which had no cost-utility ;glecaprevir/pibrentasvir need to cut down the price by 64.65% to have cost-utility. Sofosbuvir+coblopasvir increased QALYs by 0.002 0 and saved costs by 515 yuan,so it was the optimal regimen which was cost-saving. Sensitivity analysis showed that SVR rates and drug prices were the most influential factors. The probability of having cost-utility for sofosbuvir+coblopasvir was higher than glecaprevir/pibrentasvir. CONCLUSIONS :Glecaprevir/pibrentasvir need to reduce the price to achieve better affordability. Sofosbuvir+coblopasvir shows economical advantage.

摘要:OBJECTIVE:To excavate and evaluate ADR signals of SGLT 2 inhibitors as canagliflozin ,dapagliflozin and empagliflozin,and to provide reference for rational drug use in the clinic. METHODS :The proportional reporting ratio (PRR)and reporting odds ratio (ROR)were used to find the adverse drug reactions (ADR)signal of SGLT 2 inhibitors as canagliflozin , dapagliflozin and empagliflozin from the second quarter of 2013 to the third quarter of 2020 in the US FDA Adverse Event Reporting System (FAERS). The basic information (including gender ,age,reporting year ,reporting country ,severe ADR )and safety warning signals of corresponding patients in ADR report were analyzed. RESULTS :Among 6 029 375 ADR reports ,SGLT2 inhibitors of 43 807 ADR reports were concomitant and suspected drugs ;there were 19 301 ADR reports of canagliflozin ,10 960 ADR reports of dapagliflozin ,13 546 ADR reports of empagliflozin. Except for the ADR patients with unknown gender and missing age ,the gender distribution of the included reports was balanced ,mainly in the range of 50-75 years old. The reporting year was mainly in 2018,and the main reporting country was the United States ,with“hospitalization or prolonged hospitalization ” as the main serious ADR. A total of 573 ADR signals were obtained ,involving 26 systems,mainly focusing on metabolic and nutritional diseases ,endocrine disorders ,kidney and urinary system disease ,infection and invasion diseases ,etc. The results showed that there were 14 main ADR signals in the top 10 ADR of canagliflozin ,dapagliflozin and empagliflozin. The strongest ADR signals of dapagliflozin and empagliflozin were ketoacidosis (PRR=119.64/140.11,95%CI lower limit of ROR =148.28/ 178.78)and fungal infection (PRR=47.76/34.77,95% CI lower limit of ROR =50.69/36.28);except above signals in addition , toe amputation (PRR=489.79,95%CI lower limit of ROR =520.15)and osteomyelitis (PRR=61.42,95%CI lower limit of ROR=65.38)were strong in the ADR signals of canagliflozin. CONCLUSIONS :SGLT2 inhibitors have a higher security risk in metabolic and nutritional diseases ,endocrine disorders ,kidney and urinary system ,and infection and intrusion diseases. Dapagliflozin,canagliflozin and empag liflozin are prone to cause ADR such as ketoacidosis and fungal infection ,while canagliflozin is easy to cause ADRs such as toe amputation and osteomyelitis.

摘要:OBJECTIVE:To investigate the risk factors for the recurrence of ischemic stroke after secondary prevention ,and to observe the effect of glutathione on 4-HNE. METHODS :Totally 97 patients with ischemic stroke relapse within one year were treated from Oct. 2017 to Oct. 2019 in 3 hospitals as the Second Affiliated Hospital of Shandong First Medical University due to cerebral thrombosis or cerebral embolism as observation group ,and 97 non-recurrence patients in the same period were paired as control group. The patients in the observation group were randomly divided into conventional treatment group (49 cases)and drug intervention group (48 cases). The patients in conventional treatment group received routine treatment such as cerebral blood flow recanalization, improving circulation , controlling blood pressure , maintaining blood glucose , treating hyperlipidemia and arrhythmia during hospitalization. Drug intervention group was additionally given Glutathione for injection 1.8 g intragastrically , once a day ,on the basis of conventional treatment group. 4-HNE concentrations in plasma were determined at admission and 14 days after treatment ,the genetic type of ALDH2 and type of TAST were determined at admission. Multiple liner regression was used to analyze the factors associated with 4-HNE increasing ; conditional Logistic analysis was used to identify independent risk factors resulting to ischem ic stroke recurrence after secondary prevention. RESULTS :The plasma concentration of 4-HNE at admission and the percentage of arte ry atherosclerosis patients in observation group were significantly higher than control group(P<0.05). The distribution of each ALDH2 genotype in 2 groups complied with Hardy-Weinberg genetic equilibrium (P> 0.05). The proportion of patients carrying ALDH2*2 allele in observation group (50.50%)was significantly higher than control group(36.08%)(P<0.05). ALDH2*2 allele [ B=2.33,95%CI(1.35,5.50),P=0.03] and artery atherosclerosis [ B=1.90,95%CI (1.29,3.74),P=0.04] were significantly associated with the elevation of plasma concentration of 4-HNE;artery atherosclerosis [OR= 2.93,95%CI(1.84,4.67),P<0.01],stroke family history [OR =1.50,95%CI(1.18,1.90),P=0.04],elevated plasma concentration of 4-HNE [OR =1.34,95%CI(1.11,1.62),P=0.04] were regarded as independent risk factors associating with ischemic stroke recurrence after secondary prevention. After intervention ,plasma concentration of 4-HNE in drug intervention group and conventional treatment group was significantly lower than before intervention (P<0.05);there was no statistical significance between 2 groups(P>0.05). CONCLUSIONS :Stroke family history ,artery atherosclerosis and the elevation plasma concentration of 4-HNE are independent risk factors associating with ischemic stroke recurrence after secondary prevention. Although drug intervention can reduce the elevated plasma concentration of 4-HNE,the effect of additional use of glutathione is not more significant than that of conventional treatment.

摘要:OBJECTIVE:To study influential factors for medication compliance of phosphate binder in patients with maintenance hemodialysis and the effects of pharmacist intervention ,and to improve medication compliance and the effects of disease control. METHODS :The patients with maintenance hemodialysis who were treated in the blood purification center of our hospital from Jun. to Dec. ,2019 were selected for questionnaire survey. The questionnaires involved general information , medication compliance of phosphate binder ,disease and medicine related knowledge ,social support ,self-efficacy. The t-test,χ2 test and multivariate Logistic regression analysis were used to analyze influential factors for medication compliance. The patients were randomly divided into pharmaceutical intervention group and non-intervention group. Intervention group were provided with pharmaceutical care for 3 months according to risk factors. Blood phosphorus level and medication compliance was compared between 2 groups. RESULTS :Totally 298 patients completed the survey (effective recovery rate of 96.1%). Among them ,163 patients(54.7%)had good adherence to phosphate binder ,while 135 patients(45.3%)had poor compliance. Results of single factor analysis showed that medication compliance of phosphate binder was closely associated with age ,dialysis duration , parathyroid hormone levels ,total daily dose ,daily dose of phosphate binder ,disease and medicine related knowledge scores , social support ,self-efficacy(P<0.05). Results of multivariate Logistic regression analysis showed that total daily dose ,daily dose of phosphate binder ,disease and medicine related knowledge scores ,social support and self-efficacy were the influential factors for medication compliance (P<0.05 or P<0.01). Medication compliance ,disease control status ,disease and medicine related knowledge score , social support and self-efficacy in pharmaceutical intervention group were significant improved , blood phosphorus level was significant lower ,compared with non-intervention group (P<0.05). CONCLUSIONS :Independent risk factors influencing medication compliance of phosphate binder include total daily dose ,daily dose of phosphate binder ,disease and medicine related knowledge scores ,social support and self-efficacy. The patients with maintenance hemodialysis have poor compliance to phosphate binder. Pharmacists should take individualized and targeted intervention measures for the above risk factors,which can effectively improve the medication compliance and disease prognosis of patients.
