Objective To investigate the effect of daptomycin on the serum levels of proclacitonin (PCT) and copeptin in septicopyemia patients induced by methicillin-resistant Staphylococcus aureus (MRSA). Methods 54 cases septicopyemia patients induced by MRSA were selected and divided into two groups, 27 cases in each group. The two groups received fluid replacement therapy and nutrition support, the control group received vancomycin (0.5g per times, three times daily) with intravenous drip, and the study group received daptomycin (6mg/kg, once daily) with intravenous drip. The serum PCT, proclacitonin levels pre-and post-treatment in two groups were detected, the acute physiology and chronic health evaluationⅡ (APACHEⅡ) and sepsis-related organ failure assessment (SOFA) were used to evaluate the patients' condition, the clearance time of pathogenic bacteria was recorded and the clinical efficacy was compared between two groups. Results Compared with before treatment, serum PCT, C-reactive protein (CRP), interleukin-1β(IL-1β) and IL-6 in two groups decreased(P<0.01), the count of WBC, NE% and copeptin decreased (P<0.01), the APACHEⅡ and SOFA score were lower(P<0.05); compared with the control group, the PCT, CRP, IL-1 beta and IL-6 in study group were lower(P<0.05), the count of WBC, NE% and copeptin level were lower(P<0.05), APACHEⅡ and SOFA score were lower(P<0.05), the pathogen clearance rate was higher(P<0.05), clearance time was shorter(P<0.05), the total efficiency was higher(P<0.05). Conclusion Daptomycin can reduce serum PCT and copeptin in patients with septicopyemia induced by MRSA, and remove pathogenic bacteria rapidly, inhibit the inflammatory reaction, safe and reliable.

Objective To evaluate the safety and effectiveness of 2μm Thulium laser vaporization enucleation (Thu-VEP) in the treatment of benign prostate hyperplasia (BPH). Methods A total of 145 patients with BPH were randomized into two groups including patients underwent ThuVEP and patients underwent standard transurethral resection of the pros-tate (TURP). The intraoperative blood loss,flushing fluid quantity,operation time,bladder irrigating time,catheterization time,the international prostate symptom score (IPSS),quality of life score (QOL),the maximum flow rate (Qmax),the post-void residual (PVR) and complications were observed in two groups. Results There were no significant differences in pa-tient age, preoperative duration, prostate weight, IPSS score,QOL score,Qmax and RUV between two groups. Patients in two groups were performed surgery successfully. The values of blood loss, bladder irrigating time and catheterization time were significantly less in ThuVEP group than those of TUEP group (P<0.05). There were no postoperative complications in pa-tients of ThuVEP group. There were 5 cases of complications in TUEP group after operation. The values of IPSS score,QOL score,Qmax and RUV were significantly different after 3-12-month follow up than those before operation(P<0.01),but no significant difference between two groups. Conclusion ThuVEP is a safe and more effective treatment than that of TURP for patients with BPH. ThuVEP can significantly improve the quality of life, and reduce complications in patients with BPH.

An analytical liquid-liquid extraction-gas chromatography–mass spectrometry (LLE-GC-MS) method was established for the determination of genotoxic impurities including methyl methanesulfonate (MMS), ethyl methanesulfonate (EMS) and isopropyl methanesulfonate (IMS) in methanesulfonic acid. An Agilent HP-1MS capillary column (30 m × 0.32 m, 1 μm) was used for separating the analytes by programmed heating with the inlet temperature of 220 °C. Mass spectrometry was operated in positive ion mode, and selective ion monitors were set at m/z 80 for MMS, m/z 79 for EMS, m/z 123 for IMS and m/z 56 for internal standard butyl methanesulfonate (BMS). Results showed that the baseline separation of MMS, EMS and IMS was achieved, and the blank extraction solution had no interference; good linearity was achieved in the range of 37-1 480 ng/mL for three alkyl methanesulfonates; The mean recoveries of MMS, EMS, IMS were 104.99%, 107.26%,108.85%, respectively, with RSD ≤ 4.54%. The established method has the characteristics of specific, sensitive, accurate, stable and good versatility, and has been used for the detection and control of alkyl methanesulfonate impurities in methanesulfonic acid from a variety of manufacturers.

Objective:To investigate the correlation between strong ion gap (SIG) and prognosis of adult hospitalized patients who experienced cardiac arrest (CA).Methods:A retrospective cohort study was conducted on adult CA patients (≥18 years old) who were admitted to the intensive care unit (ICU) for the first time from the Medical Information Mart for Intensive Care Ⅲ (MIMIC-Ⅲ) database from 2001 to 2012. The patients were divided into 3 groups based on the tertiles of serum SIG value. The clinical baseline characteristics and related data of CA patients were compared. Kaplan-Meier method was used to draw the 28- and 90-day cumulative survival curves of CA patients. Meanwhile, the log-rank test was used to compare the differences in the survival curves among different groups, and Cox proportional hazard regression model was established to analyze whether SIG was an independent predictor of all-cause mortality in CA patients.Results:Six hundred and six adult CA patients were eligible for final analysis. The patients were divided into 3 groups based on the tertiles of serum SIG value [<3.91 mmol/L ( n=202), 3.91~7.32 mmol/L ( n=202) and >7.32 mmol/L ( n=202)]. The mean age was (66.91±15.95) years and 382 patients (63.04%) were male. The all-cause mortality rates of ICU, 28 days and 90 days were 36.47%, 49.17% and 56.93%, respectively. There were significant differences in SOFA score, SIG, anion gap, pH, lactic acid, white blood cells, prothrombin time, creatinine, blood potassium, blood phosphorus, hypertension, coronary heart disease, cardiogenic shock, and ICU, 28-day and 90-day all-cause mortality among the 3 groups (all P<0.05). The Kaplan-Meier survival curves showed that the 28- and 90-day cumulative survival rates of CA patients decreased gradually with the increase of SIG level, and the differences were statistically significant among the 3 groups (all P<0.001). Multivariate Cox proportional hazard models showed that the increase of SIG level (>7.32 mmol/L) was an independent risk factor for 28-day ( HR=1.610, 95% CI: 1.177-2.203, P=0.003) and 90-day all-cause mortality ( HR=1.506, 95% CI: 1.123-2.019, P=0.006) among CA patients, after adjusting for the related confounders. Conclusions:The elevated SIG level (>7.32 mmol/L) is an independent predictor of 28- and 90-day all-cause mortality in CA patients. The calculation of SIG level in these patients is helpful for early identification of patients with poor prognosis.

OBJECTIVE: To evaluate the effects of ivabradine in the treatment of heart failure on medical insurance fund budget in China, and to provide support evidence of related economical evaluation for medical insurance department to solve the problem of reimbursement admission of the drug in hospital outpatient department and the establishment of drug list in hospital. METHODS: Excel decision tree model was used. Pharmacoeconomic analysis was conducted based on the data reported in domestic literatures over the years. Firstly, according to the prevalence rate of heart failure in China, the number of patients with heart failure was estimated, which accorded with NYHA cardiac function class Ⅱ-Ⅳ, systolic blood pressure dysfunction and ivabradine indication. Then the cost of ivabradine was estimated. Secondly, the total number of hospitalizations and the cost of hospitalization due to heart failure were estimated. Finally, the cost of ivabredine and the cost of treatment saved by avoiding re-hospitalization due to the use of ivabredine were considered comprehensively. Static budget impact analysis was conducted to evaluate the effects of the use of ivabredine on medical insurance fund budget. RESULTS: The prevalence rate of heart failure in China was raised to 1.3% in 2013. It was estimated that the number of heart failure patients between 35-75 years old in China could be about 8.51 million and total hospitalization times was about 4.32 million per year. The economic burden of hospitalization in heart failure patients was about 168.940 billion yuan in whole country. Since 18% of patients could be avoided re-hospitalization after treatment with ivabradine, the cost of hospitalization could be saved by about 30.410 billion yuan, while the total cost of taking ivabradine was about 17.525 billion yuan. Therefore, the use of ivabradine could save the hidden medical cost budget by about 12.886 billion yuan, which had obvious cost-effectiveness. Static budget impact analysis results showed that by 2019-2020, the expected proportion of patients with heart failure covered by ivabradine would increased to 8.70%, and the total consumption sum would reach about 1.797 billion yuan. The incremental cost savings ratio (ICSR) showed that the cost of hospitalization could be saved by about 11 951 yuan for each additional case of heart failure treated with ivabradine; there could be 5 711 yuan of balance by deducting drug cost 6 240 yuan of ivabradine. CONCLUSIONS: The cost savings of hospitalization treated by ivabradine is not only enough to offset the cost of ivabradine itself, but also has a premium effect. The drug is of certain economy for the treatment of heart failure in China.

OBJECTIVE: To investigate the feasibility of multi-payment for drugs for rare diseases and also provide reference for rare disease treatment and the formulation of related policy. METHODS: Taking Gaucher’s disease in Qingdao as an example, the relevant medical insurance policies and drug supply were analyzed; according to the sources of financing, the economic burden of treatment drugs for patients with Gaucher’s disease in Qingdao was estimated. Based on the average total cost of patients with Gaucher’s disease in Qingdao, the drug cost burden of patients with Gaucher’s disease in the whole country was simulated according to the relevant epidemiological survey data, and the problems of medical insurance model for rare diseases in Qingdao were analyzed. RESULTS & CONCLUSIONS: A series of medical insurance policies were formulated in Qingdao. The financing mode of medical insurance includes social funds (from Qingdao Charity Federation, drugs are provided by pharmaceutical manufacturers), medical insurance funds (used for personal self-payment assistance within the scope of medical insurance co-ordination) and civil assistance (used for assistance outside the scope of medical insurance co-ordination). Imidase is currently the only approved specific drug for Gaucher’s disease in China. The designated physician, treatment and drug-taken system is adopted in Qingdao. By the end of 2017, the annual drug consumption of 8 patients in Qingdao was 38-170 bottles, totaling 686 bottles. The annual cost of treatment ranged from 786 600 to 3 519 000 yuan, totaling 1 420 200 yuan. The self-paid expenses ranged from 9 800 to 197 400 yuan (the self-paid ratio ranged from 0.46% to 8.87%), totaling 661 400 yuan. The reimbursement cost by supplementary medical insurance was 509 800 to 1 789 800 yuan (accounting for 54.59% to 65.94%), totaling 8 577 800 yuan. Three patients received civil assistance, the amount of which ranged from 23 100 to 13 000 yuan (accounting for 1.89% to 4.18%), totaling 241 400 yuan. According to the relevant epidemiological survey data (the prevalence rate was 0.15 per 100 000), it is estimated that there are about 2 093 patients with Gaucher’s disease in China. Referring to Qingdao multi-payment model, it is estimated that the total cost of drugs for Gaucher's disease in China is about 3.715 billion yuan, charitable assistance can bear 1.238 billion yuan, while medical insurance expenditure is about 2.255 billion yuan, and individual self-payment is about 222 million yuan. From the point of view of drug cost burden, the multi-payment model in Qingdao has lightened the personal burden of patients’ has achieved significant results. There are problems in Qingdao’s multi-payment model, such as “medical insurance immigration”, low drug accessibility, drug price monopoly, three-level disease prevention needs to be strenghten, etc. The state or provinces and cities can refer to Qingdao model when formulating policies related to rare diseases. Great importance should be paid attention to the existing problems.
