RESUMO
With the premise of drug safety and effectiveness, pharmacoeconomic evaluation can provide optimal solutions for diversified decision-making application scenarios from different research perspectives while maximizing the rational utilization of existing healthcare resources. Chinese patent medicine is an essential component of pharmaceutical utilization in China and a significant part of healthcare expenditure in China. However, the economic evaluation of post-marketing Chinese patent medicine is lacking. These evaluations often lack standardization, exhibit varying quality, and are unable to effectively support healthcare decisions, indicating a need for improvement in overall quality. Given this situation, this project has gathered leading experts from China and has strictly adhered to the requirements of the group standards set by the China Association of Traditional Chinese Medicine in developing Guidelines for economic evaluation of post-marketing Chinese patent medicine, aiming to provide methodological guidance for the post-market pharmacoeconomic evaluation of Chinese patent medicine, enhancing the standardization of pharmacoeconomic evaluations of Chinese patent medicine and the scientific validity of research results, and thereby elevating the overall quality of pharmacoeconomic evaluations for post-marketing Chinese patent medicine. The guidelines adhere to the framework provided by relevant laws and regulations in China and technical guidance documents. It is based on guidance from traditional Chinese medicine(TCM) theories, focusing on the unique characteristics of TCM. It covers various aspects of pharmacoeconomic evaluation, including fundamental principles, research topic selection, research question definition, study design type selection, cost identification and measurement, health outcomes, and evaluation methods. The guidelines offer methodological recommendations and decision guidance to address common issues and challenges in the pharmacoeconomic evaluation of post-marketing Chinese patent medicine.

Thrombocytopenia can cause substantial morbidity and mortality in critically ill patients. There are multiple etiology factors and various mechanisms associated with thrombocytopenia, of which drug-induced thrombocytopenia (DITP) deserves attention. Herein, we describe a case of severe thrombocytopenia during intensive care unit (ICU) hospitalization that was likely to be associated with vancomycin. By revealing the process of identifying this case of DITP and reviewing relevant clinical studies, a risk alert of vancomycin-related severe hematotoxicity should be considered.
RESUMO
Aims: To determine the risk of liver injury associated with the use of different intravenous lipid emulsions (LEs) in large populations in a real-world setting in China. Methods: A prescription sequence symmetry analysis was performed using data from 2015 Chinese Basic Health Insurance for Urban Employees. Patients newly prescribed both intravenous LEs and hepatic protectors within time windows of 7, 14, 28, 42, and 60 days of each other were included. The washout period was set to one month according to the waiting-time distribution. After adjusting prescribing time trends, we quantify the deviation from symmetry of patients initiating LEs first and those initiating hepatic protectors first, by calculating adjusted sequence ratios (ASRs) and relevant 95% confidence intervals. Analyses were further stratified by age, gender, and different generations of LEs developed. Results: In total, 416, 997, 1,697, 2,072, and 2,342 patients filled their first prescriptions with both drugs within 7, 14, 28, 42, and 60 days, respectively. Significantly increased risks of liver injury were found across all time windows, and the strongest effect was observed in the first 2 weeks [ASR 6.97 (5.77-8.42) â¼ 7.87 (6.04-10.61)] in overall patients. In subgroup analyses, female gender, age more than 60 years, and soybean oil-based and alternative-LEs showed higher ASRs in almost all time windows. Specially, a lower risk for liver injury was observed in the first 14 days following FO-LEs administration (ASR, 3.42; 95% CI, 0.81-14.47), but the risk started to rise in longer time windows. Conclusion: A strong association was found between LEs use and liver injury through prescription sequence symmetry analysis in a real-world setting, which aligns with trial evidence and clinical experience. Differences revealed in the risks of liver injury among various LEs need further evaluation.
RESUMO
Aim: This study aimed to evaluate the cost-effectiveness of CYP2C19 loss-of-function(LOF) allele-guided antiplatelet therapy compared with the universal use of clopidogrel or ticagrelor among Chinese patients with acute coronary syndrome undergoing percutaneous coronary intervention. Methods: A two-part cost-effectiveness model comprising of a 1-year decision tree and a long-term Markov model was utilized to simulate outcomes of three treatment strategies: universal use of clopidogrel (75 mg daily) or universal use of ticagrelor 90 mg twice daily for all patients and CYP2C19 LOF-guided therapy (LOF allele carriers receiving ticagrelor, LOF allele noncarriers receiving clopidogrel). Model outcomes included quality-adjusted life years (QALYs) gained, direct medical costs and incremental cost-effectiveness ratios (ICERs). ICERs less than one-time gross domestic product per capita in China 59,660 yuan/QALY were considered cost-effective. Results: Base-case analysis showed 'universal ticagrelor use' was cost-effective for an ICER of 33,875 yuan per QALY gained compared with 'universal clopidogrel use' of which gained a 1.6932 QALYs at lowest life-long cost of 2450 yuan. CYP2C19 LOF-guided therapy had an effectiveness of 1.6975 QALYs at a cost of 2812 yuan, for an ICER of 84,118 yuan per QALY gained relative to 'universal clopidogrel use'. Sensitivity analysis demonstrated that base-case results were significantly affected by five factors: the risk ratio of 'non-fatal myocardial infarction', 'non-fatal stroke' and 'cardiovascular death' in ticagrelor versus clopidogrel and the annual costs of clopidogrel and ticagrelor. According to the results of Monte Carlo simulation, when willing to pay is about 32,000 yuan, patients willing to receive clopidogrel or ticagrelor are approximately equal. Conclusion: Optimal antiplatelet treatment is affected by lots of factors. The results of our study demonstrated that 'universal ticagrelor use' was cost-effective compared with 'universal clopidogrel use' for Chinese acute coronary syndrome patients with percutaneous coronary intervention.

Background The clinical pharmacist has been an important partner in clinical treatment team. In China, there is no systematic review to evaluate the effectiveness of clinical pharmacy services on patients' outcomes such as hospitalization days, readmission rate and mortality. Aim of the review To investigate the impact of clinical pharmacist services on patients' length of hospitalization, readmission and mortality in China. Methods A literature search was performed in PubMed, EMBASE, Cochrane Library, clinicaltrials.gov, and a Chinese database (up to January 2019). Randomized control trials or pre- to post-intervention comparison studies were included to investigate the impact of clinical pharmacist-led interventions on the length of stay, readmission rate and mortality of inpatients. Basic information, intervention and therapeutic area were extracted. Results After screening all articles from the mentioned databases, 14 studies were included for meta- analysis and subgroup analysis. Most studies focused on cardiology and respiratory diseases. Results show that clinical pharmacist services can reduce the length of stay of inpatients (MD: - 3.00, 95% CI - 4.72 to - 1.29, P < 0.01) and the readmission rate (RR 0.44, 95% CI 0.35-0.56, P < 0.01) as well as the mortality of patients during hospitalization (RR 0.57, 95% CI 0.35-0.92, P = 0.02). Conclusions Clinical pharmacist-led interventions could significantly reduce Chinese patients' length of hospitalization and readmission rate. More studies are needed to confirm the relationship between the clinical pharmacist-led interventions and patients' mortality.

AIM: To identify common drug-related problems (DRPs) during pharmacy intervention and consultation in an intensive care unit (ICU); to explore the gap between physicians and pharmacists on their understanding of each other's capabilities and needs. METHOD: We conducted a single-center prospective study in the ICU of a tertiary academic hospital for 21 months. A pharmaceutical care (PC) model was implemented by a pharmacy team, and data were collected during pharmacy intervention and consultation. Data analysis was performed on identified DRPs, causes and their relationships. DRPs' frequency during intervention and consultation was compared. Problem-level descriptive analysis and network analysis were conducted using R 3.6.3. RESULT: Implementation of PC model greatly improved the efficacy of pharmacists in both interventions proposed to solve DRPs (from 13.6 to 20.1 cases per month) and number of patients being closely monitored (from 7.7 to 16.9 per month). Pharmacists identified 427 DRPs during pharmacy intervention with primarily adverse drug events (ADEs, 34.7%) and effect of treatment not optimal (25.5%), and 245 DRPs during consultation (mainly ADEs, 58.4%). About three-fifths DRPs were caused by antibiotics. Comparing DRPs identified during pharmacy intervention and consultation, physicians consulted pharmacists more on questions related to medication safety, while pharmacists also paid attention to treatment effectiveness, which was consulted less commonly. CONCLUSION: Implementation of PC model is beneficial in guiding pharmacy practice and improving efficacy especially under limited human resources. Physicians and pharmacists shall continue ensuring drug safety and be familiar with the scope of PC and clinical need for a better cooperation.
RESUMO
AIMS: Ciclosporin (CsA), which is widely used in autoimmune disease and transplantation, has a narrow therapeutic index. It also shows considerable interindividual variability in its pharmacokinetics, which may be attributable to polymorphisms of the multidrug efflux pump P-glycoprotein, encoded by MDR-1. The aim was to determine the role of genetic polymorphisms in MDR-1 with respect to interindividual variability of CsA blood concentrations in myasthenia gravis (MG) patients. METHODS: MG patients (n = 129) receiving CsA were genotyped for MDR-1 1236C-->T (exon 12), 2677G-->T (exon 21) and 3435C-->T (exon 26). Trough blood and peak blood concentrations were determined to see if there was correlation with the corresponding genotype. RESULTS: We observed a trend for CsA blood concentrations, especially peak blood concentrations, to be higher with the wild-type allele compared with minor alleles in genotype and haplotype. Furthermore, under the same CsA regimen, it was found that the trough concentrations of variant genotype (ABCB1 1236TT or ABCB1 2677TT) were significant greater than those of wild-type (ABCB1 1236CC or ABCB1 2677GG, respectively) (P = 0.0222 and 0.0081). The trough concentrations of wild-type haplotype pair group were significantly lower those that of the mutant type pair group (TT-TT-TT) (P = 0.007). CONCLUSIONS: ABCB1 polymorphisms in both genotype and haplotype may have a minor effect on the CsA blood concentrations.

PURPOSES: The objective of the study was to identify the trends and relations between antimicrobial resistance (AMR) and antibiotic use in the Xinjiang Uyghur Autonomous Region in Western China from 2014 to 2016. METHODS: A retrospective, descriptive analysis of AMR prevalence, and trends and relations between AMR and antibiotic use during the 3-year period was performed. RESULTS: Third-generation cephalosporin-resistant Escherichia coli was the most prevalent resistant pathogen in terms of both resistance density and resistance proportion. A significant correlation was found between resistance density of third-generation cephalosporin-resistant Klebsiella pneumoniae and the use of beta-lactam-beta-lactamase inhibitor combinations (cc=0.63, p=0.03), quinolones (cc=0.60, p=0.04), and carbapenems (cc=0.76, p=0.004), among which only beta-lactam-beta-lactamase inhibitor combinations showed a significant correlation with third-generation cephalosporin-resistant E. coli (cc=0.63, p=0.03). For carbapenem-resistant Pseudomonas aeruginosa, not only carbapenem use (cc=0.65, p=0.02) but also penicillin (cc=0.76, p=0.004) and quinolone (cc=0.69, p=0.01) use showed significant correlation. A strong correlation was observed between the resistant proportion of third-generation cephalosporin-resistant E. coli and only the use of beta-lactam-beta-lactamase inhibitor combinations (cc=0.61, p=0.03). CONCLUSION: The association between antibiotic use and AMR, especially the implication of the difference in resistance density and resistance proportion, is crucial for local physicians and decision-makers to better use of antibiotics and allocate healthcare resources more effectively, as well as to better implement antimicrobial stewardship and effective infection control strategies.

OBJECTIVE: Investigate the association between P2Y12 Purinoceptor (P2RY12) polymorphisms and adverse clinical events in coronary artery disease (CAD) patients treated with clopidogrel. METHODS: We performed a comprehensive database search, with a particular focus on P2RY12 polymorphisms and their effects on clopidogrel-treated CAD patients, in the PubMed, EMBASE, Cochrane Library, clinicaltrials.gov, Web of Science, and Chinese databases from their inceptions to April 8, 2017. The primary endpoints were composite ischemic events (including cardiovascular and cerebrovascular ischemic events), the secondary endpoints were independent cardiovascular events (mortality, non-fatal myocardial infarction, stent thrombosis, unstable angina, and target vessel revascularization) and the safety endpoints were bleeding events. RESULTS: Overall 10 studies and 10,810 clopidogrel-treated CAD patients were studied in the present work. Subjects of the common alleles of P2RY12 polymorphisms showed higher risk for composite ischemic events compared to non-carriers (nâ¯=â¯434 of 3268[13.3%] vs. nâ¯=â¯646 of 6133[10.5%]; RR: 1.39, 95%CI: 1.14-1.69; pâ¯=â¯0.001). These allele carriers also showed increased risk for stent thrombosis (RR: 2.67, 95%CI: 1.03-6.91; pâ¯=â¯0.04), myocardial infarction (RR: 1.60, 95%CI: 1.06-2.42; pâ¯=â¯0.03), and unstable angina (RR: 1.72, 95%CI: 1.37-2.16; pâ¯<â¯0.00001) (vs. non-carriers). There was no significant difference between two groups in terms of mortality risk, target vessel revascularization or bleeding (pâ¯=â¯0.29; pâ¯=â¯0.48, respectively). CONCLUSIONS: P2RY12 gene polymorphisms might associate with higher risk of composite ischemic events, stent thrombosis, non-fatal myocardial infarction, unstable angina. While we found no significant effect on mortality, target vessel revascularization or bleeding.

OBJECTIVE: To investigate the association between PEAR1 (platelet endothelial aggregation receptor-1) polymorphisms and cardiovascular outcomes in acute coronary syndrome (ACS) in patients treated with aspirin and clopidogrel. METHODS: We genotyped eight common PEAR1 SNPs (rs2768759, rs12566888, rs12041331, rs11264579, rs2644592, rs822441, rs822442, and rs4661012), also CYP2C19*2 (rs4244285) and CYP2C19*3 (rs4986893) in 196 Chinese patients with ACS. We assessed the association between PEAR1 polymorphisms and platelet inhibition rate (PIR) measured by thromboelastography (TEG). The ischemic events over 12â¯months were recorded, and the relationship between PEAR1 polymorphisms and ischemic events was analyzed. RESULTS: Genetic mutations in rs822441, rs822442, and CYP2C19â2/â3 alleles were significantly associated with a decrease in PIR induced by adenosine diphosphate (ADP). Carriers of the T allele in rs11264579 were less likely to have ischemic events compared with non-carriers (HR: 0.53, 95% CI: 0.30-0.94, Pâ¯=â¯.031). By contrast, carriers of the A allele in rs822442 had increased risk of ischemic events (HR: 1.82, 95% CI: 1.02-3.24, Pâ¯=â¯.043). However, these significant associations disappeared after controlling family-wise error rate. CONCLUSIONS: For Chinese patients with ACS treated with aspirin and clopidogrel, genetic mutations in rs822441/rs822442 in PEAR1 correlated significantly with platelet activity after adjusting for CYP2C19 *2/*3 alleles. The rs11264579 T allele might be a protective factor for ischemic events; rs11264579, rs822441, and rs822442 might be genetic markers worthy of further research.

The consumption of antibiotics is a major driver in the development of antimicrobial resistance. This study aims to identify the trends and patterns of the total antibiotic consumption in China's tertiary hospitals from 2011 to 2015 by retrospectively analyzing aggregated monthly surveillance data on antibiotic sales made to 468 hospitals from 28 provinces. Antibiotic consumption was expressed in DDD per 1,000 inhabitants per day (DID). We compared population weighted antibiotic consumption patterns in China with European countries using indicators from the European Surveillance of Antimicrobial Consumption (ESAC). Total antibiotic consumption, including all the specific antibiotic class except for aminoglycoside antibacterials, were significantly increased during the study period from an average of 7.97 DID in 2011 to 10.08 DID in 2015. In 2015, the eastern regions of China consumed the most antibiotics using population denominator while the western regions consumed the most using inpatient denominator. Cephalosporins accounted for 28.6% of total DID, followed by beta-lactam-beta-lactamase inhibitor combinations (20.0%), macrolides (17.4%), and fluoroquinolones (10.5%). Antibiotic in parenteral form accounted for nearly half of all antibiotics. Although over the past few years major efforts had been made to reduce the risks of excessive antibiotic use through antibiotic stewardship, total antibiotic consumption showed a significant upward trend during the study period. A consistent preference for cephalosporins, macrolides, beta-lactam-beta-lactamase inhibitor combinations, as well as parenteral preparations was observed.

BACKGROUND: Though many countries, including China, are moving towards malaria elimination, malaria remains a major global health threat. Due to the spread of antimalarial drug resistance and the need for innovative medical products during the elimination phase, further research and development (R&D) of innovative tools in both epidemic and elimination areas is needed. This study aims to identify the trends and gaps in malaria R&D in China, and aims to offer suggestions on how China can be more effectively involved in global malaria R&D. METHODS: Quantitative analysis was carried out by collecting data on Chinese malaria-related research programmes between 1985 and 2014, invention patents in China from 1985 to 2014, and articles published by Chinese researchers in PubMed and Chinese databases from 2005 to 2014. All data were screened and extracted for numerical analysis and were categorized into basic sciences, drug/drug resistance, immunology/vaccines, or diagnostics/detection for chronological and subgroup comparisons. RESULTS: The number of malaria R&D activities have shown a trend of increase during the past 30 years, however these activities have fluctuated within the past few years. During the past 10 years, R&D on drug/drug resistance accounted for the highest percentages of research programmes (32.4%), articles (55.0% in PubMed and 50.6% in Chinese databases) and patents (45.5%). However, these R&D activities were mainly related to artemisinin. R&D on immunology/vaccines has been a continuous interest for China's public entities, but the focus remains on basic science. R&D in the area of high-efficiency diagnostics has been rarely seen or reported in China. CONCLUSIONS: China has long been devoted to malaria R&D in multiple areas, including drugs, drug resistance, immunology and vaccines. R&D on diagnostics has received significantly less attention, however, it should also be an area where China can make a contribution. More focus on malaria R&D is needed, especially in the area of diagnostics, if China would like to contribute in a more significant way to global malaria control and elimination.

OBJECTIVE: To investigate a possible association between common variations of the P2RY12 and the residual clopidogrel on-treatment platelet reactivity after adjusting for the influence of CYP2C19 tested by thromboelastography (TEG). METHODS: One hundred and eighty patients with acute coronary syndrome (ACS) treated with clopidogrel and aspirin were included and platelet function was assessed by TEG. Five selected P2RY12 single nucleotide polymorphisms (SNPs; rs6798347, rs6787801, rs6801273, rs6785930, and rs2046934), which cover the common variations in the P2RY12 gene and its regulatory regions, and three CYP2C19 SNPs (*2,*3,*17) were genotyped and possible haplotypes were analyzed. RESULTS: The high on-treatment platelet reactivity (HTPR) prevalence defined by a platelet inhibition rate <30% by TEG in adenosine diphosphate (ADP)-channel was 69 (38.33%). Six common haplotypes were inferred from four of the selected P2RY12 SNPs (denoted H0 to H5) according to the linkage disequilibrium R square (except for rs2046934). Haplotype H1 showed a significantly lower incidence of HTPR than the reference haplotype (H0) in the total study population while haplotypes H1 and H2 showed significantly lower incidences of HTPR than H0 in the nonsmoker subgroup after adjusting for CYP2C19 effects and demographic characteristics. rs2046934 (T744C) did not show any significant association with HTPR. CONCLUSIONS: The combination of common P2RY12 variations including regulatory regions rather than rs2046934 (T744C) that related to pharmacodynamics of clopidogrel in patients with ACS was independently associated with residual on-clopidogrel platelet reactivity. This is apart from the established association of the CYP2C19. This association seemed more important in the subgroup defined by smoking.

BACKGROUND: China is actively promoting regulation of rare diseases, rare disease and orphan drugs have been formally incorporated into the national planning. However, few studies have been done to evaluate the affordability of rare disease patients in China. This study aims to provide policy recommendations for the establishment of social security mechanism for rare diseases in China, so as to address the problem of poverty caused by these diseases. METHODS: A total of 7 rare diseases were selected by Delphi method. Affordability of treatment for the 7 rare diseases was assessed through annual per capital income, catastrophic expenditure and impoverishment expenditure among urban and rural residents in China. RESULTS: Assessed through annual per capital income, health expenditure for the 7 rare diseases are all rather high. The highest health expenditure is equivalent to income of 69.34 years of one urban resident, and the burden is heavier for rural residents. Through catastrophic expenditure assessment, proportions of the population experiencing catastrophic expenditure caused by the 7 rare diseases are all under 0.167 . However, once one is ill and taking medications, he will suffer from catastrophic health expenditure. Through impoverishment expenditure assessment, the proportions of impoverishment payment are low among both urban and rural residents, but the 7 rare diseases could lead nearly 4.6 million people into poverty on a national scale. CONCLUSION: The affordability of treatment for rare disease as well as orphan drugs is rather poor. Residents of different income levels all have difficulties to afford the treatment for rare diseases, so poverty caused by rare diseases is quite widespread. Therefore, social security mechanism for rare disease patients should be established and specific payment pattern for orphan drugs should be set up.

BACKGROUND: China has not established social security system for rare diseases. Rare diseases could easily impoverish patients and their families. Little research has studied the equity and accessibility of health services for patients with rare diseases in China. This study aimed to explore the factors that influence health expenditure of rare diseases and evaluate its equity. METHODS: Questionnaire survey about living conditions and cost burden of patients with rare diseases was conducted. Individual and family information, health expenditure and reimbursement in 2014 of 982 patients were collected. The impact of medical insurance, individual sociodemographic characteristics, family characteristics, and healthcare need on total and out-of-pocket (OOP) health expenditures was analyzed through the generalized linear model. Equity of health expenditure was evaluated by both concentration index and Lorenz curve. RESULTS: Of all the surveyed patients, 11.41% had no medical insurance and 92.10% spent money to seek medical treatment in 2014. It was suggested female (P = 0.048), over 50 years of age (P = 0.062), high-income group (P = 0.021), hospitalization (P = 0.000), and reimbursement ratio (RR) (P = 0.000) were positively correlated with total health expenditure. Diseases not needing long-term treatment (P = 0.000) was negatively correlated with total health expenditure. Over 50 years of age (P = 0.065), high-income group (P = 0.018), hospitalization (P = 0.000) and having Urban Employee Basic Medical Insurance (UEBMI) (P = 0.022) were positively correlated with OOP health expenditure. Patient or the head of the household having received higher education (P = 0.044 and P = 0.081) and reimbursement ratio (P = 0.078) were negatively correlated with OOP health expenditure. The equity evaluation found concentration indexes of health expenditure before and after reimbursement were 0.0550 and 0.0539, respectively. CONCLUSIONS: OOP health expenditure of patients with UEBMI was significantly more than that of patients without medical insurance. However, for any other medical insurance, there was no difference between OOP health expenditure of the insured patients and patients without insurance. The current reimbursement policies have increased the equity of health expenditure, but are biased toward high-income people.

BACKGROUND: To investigate the contributions of CYP2C19 polymorphisms to the various clopidogrel responses tested by thrombelastography (TEG) in Chinese patients with the acute coronary syndrome (ACS). METHODS: Patients were screened prospectively with ACS diagnose and were treated with clopidogrel and aspirin dual antiplatelet therapy. CYP2C19 loss of function (LOF) and gain of function (GOF) genotype, adenosine 5'-diphosphate (ADP)-channel platelet inhibition rate (PIR) tested by TEG and the occurrence of 3-month major adverse cardiovascular events and ischemic events were assessed in 116 patients. RESULTS: High on-treatment platelet reactivity (HTPR) prevalence defined by PIR <30% by TEG in ADP-channel was 32.76% (38/116). With respect to the normal wild type, CYP2C19*2, and *3 LOF alleles, and *17 GOF alleles, patients were classified into three metabolism phenotypes: 41.38% were extensive metabolizers (EMs), 56.90% were intermediate metabolizers (IMs), and 1.72% were poor metabolizers (PMs). Of the enrolled patients, 31.47%, 5.17%, and 0.43%, respectively, were carriers of *2, *3, and *17 alleles. The HTPR incidence differed significantly according to CYP2C19 genotypes, accounting for 18.75%, 41.54%, and 100.00% in EMs, IMs, and PMs, respectively. Eighteen (17.24%) ischemic events occurred during the 3-month follow-up, and there was a significant difference in ischemic events between HTPR group and nonhigh on-treatment platelet reactivity group. CONCLUSIONS: Genetic CYP2C19 polymorphisms are relative to the inferior, the antiplatelet activity after clopidogrel admission and may increase the incidence of ischemic events in patients with ACS.

We have demonstrated that oral arsenic (Realgar-Indigo naturalis formula, RIF) plus all-trans retinoic acid (ATRA) is not inferior to intravenous arsenic trioxide (ATO) plus ATRA as the first-line treatment of acute promyelocytic leukemia (APL). To compare the cost-effectiveness of oral and intravenous arsenic, we analyzed the results of 30 patients in each group involved in a randomized controlled trial at our center. The median total medical costs were $13,183.49 in the RIF group compared with $24136.98 in the ATO group (p<0.0001). This difference primarily resulted from the different costs of induction therapy (p=0.016) and maintenance treatment (p<0.0001). The length of hospitalization for the RIF group was significantly lower than that for the ATO group (24 vs. 31 days, p<0.0001) during induction therapy. During maintenance treatment, the estimated medical costs were $2047.14 for each patient in the RIF group treated at home compared with $11273.81 for each patient in the ATO group treated in an outpatient setting (p<0.0001). We conclude that oral RIF plus ATRA significantly reduced the medical costs and length of hospital stay during induction and remission therapy compared with ATO plus ATRA in APL patients.

OBJECTIVE: To perform meta-analyses evaluating the efficacy of adding Liuwei Dihuang Pills (, LDP) to Western medicine in improving treatment outcomes for type 2 diabetes. METHODS: Medline, PubMed, Cochrane Library, and Chinese databases, including the Chinese National Knowledge Infrastructure were searched to identify eligible studies; i.e., if the study involved a randomized clinical trial in which the experimental group combined LDP with Western drugs and the control group used the corresponding Western drugs alone to treat type 2 diabetes. Outcomes were measured in terms of fasting blood glucose (FBG), postprandial blood glucose (2hPG) and HbA1c level. Efficacy was also measured by using control and response rates. The combined odds ratio (OR), mean difference (MD), and 95% confidence intervals (95% CI) were calculated. RESULTS: Studies included in the analysis were less adequate than expected in terms of methodological quality. A total of 1,609 patients from 18 studies were included. We found that adding LDP can lower patients' FBG (MD=0.54 mmol/L, 95% CI [0.15, 0.93], P=0.007), 2hPG (MD=1.05 mmol/L, 95% CI [0.29, 1.81], P<0.01) and HbA1c (MD=0.23, 95% CI [0.02, 0.45], P=0.008). There were also improvements in treatment response rates (OR=3.41, 95% CI [2.38, 4.90], P<0.01) and control rates (OR=2.47, 95% CI [1.91, 3.20], P<0.01). CONCLUSION: Adding LDP to Western medicine might improve treatment outcomes of diabetes, including FBG, 2hPG, response rates and control rates.

Pharmacy education in China focuses on pharmaceutical sciences, with the bachelor of science (BS) of pharmacy as the entry-level degree. Pharmacy practice curricula in these programs are centered on compounding, dispensing, pharmacy administration, and laboratory experiences, which are the traditional responsibilities for pharmacists. Additional graduate-level training is available at the master of science (MS) and the doctor of philosophy (PhD) levels, most of which concentrate on drug discovery and drug development research. Presently, the emphasis in practice is beginning to shift to clinical pharmacy. With this change, additional degree offerings are being developed to meet the growing demand for clinical pharmacists. There is also interest in developing more clinical skills in practicing pharmacists through additional non-degree training. The Ministry of Education is considering a proposal for an entry-level professional degree of master and/or doctor in clinical pharmacy similar to the doctor of pharmacy (PharmD) degree in the United States.
