Abstract:
Malaria is a critical public health problem resulting in substantial morbidity and mortality in developing countries,especially in Africa.Quinoline,dihydrofolate reductase inhibitors and artemisinin drugs are currently the main drugs for the treatment of malaria,and have good clinical application value,but have the disadvantages of poor solubility,low bioavailability and lack of targeting.To overcome these drawbacks,optimizing the anti-malarial drug dosage form has become a research hotspot at present.Various optimized dosage forms for antimalarial drugs,such as solid dispersions,cyclodextrin inclusion complexes,nanoparticles,liposomes,etc.,are now reviewed.

Abstract:
Objective To study the protective effect and explore the mechanism of monocyte locomotion inhibitor factor(MLIF) on traumatic brain injury (TBI) in rats. Methods The SD rats were randomly divided into five groups:sham operation group,model group and three MLIF groups (0.33 mg/kg,1 mg/kg,3 mg/kg).Rats were made model of brain injury by fluid percussion injury.The tail vein was administered within 30 min after TBI,once every 24 hours,and rats were administered for 7 days.Brain water content,serum levels of SOD and MDA,Hematoxylin-eosin staining and Nissl staining were used to detect the rats brain tissues. Results After rats traumatic brain injury for 24h,the brain water content in rats in three MLIF groups(0.33 mg/kg,1 mg/kg and 3 mg/kg)was significantly lower than that in model group(P<0.01),The effect of MLIF (1 mg/kg) group was the best.Compared to rats traumatic brain injury for 1d and 3d,brain water content in MLIF group (1 mg/kg) was significantly lower than that in model group (P<0.01).SOD content in serum in MLIF (1 mg/kg) group was significantly increased (P <0.01) and MDA content in serum in MLIF (1 mg/kg) group was significantly decreased (P<0.05).HE staining and Nissl staining showed that the pathological changes of brain tissue in model group were obvious,and which in MLIF group were improved in brain tissue. Conclusion MLIF could inhibit oxidative stress and edema reaction of brain injury,which had protective effect on traumatic brain injury.

Abstract:
Objective To explore the general rule of medication usage in retired military personnel in the sanatorium. Methods The SQL statement was used to extract the electronic prescription data of all outpatients of 2015-retired military personnel of a third-A-grade hospital in Shanghai for data cleaning and classification.SPSS 19.0 was used to describe the samples and Kruskal-Wallis nonparametric test.The multiple linear regression analysis of factors related to the amount of prescription was performed. Results In 2015,a total of 383 retired military personnel visited the outpatient clinic of this third-A-grade hospitals,with an average age of 83.99±4.22 years old,with an average of 34.48±22.69 clinic visit times per person,and with 835 type of drugs (including different specifications of the same variety).The expenditure on pharmaceutical consumption was 6.66 million yuan.The per capita consumption was 17394.29±14706.94 yuan; Among them,the consumption of chemical drugs and biological preparations was 47.7 million (accounting for 71.83%).The consumption of proprietary Chinese medicines was 1.876 million (accounting for 28.17%).There is a linear correlation between per capita drug consumption and the retired military personnel's persition leval (X2),branch (X3),and the number of visits (X4).The standardized regression equation is Y=0.458X4+0.422X2+0.252X3. Conclusion The outpatient drug consumption and disease spectrum of retired military personnel is basically consistent.The outpatient drug consumption of retired cadres is not limited to health funding guarantee standard,but,the difference of the retired military personnel's drug consumption between the directly affiliated branch and Joint Logistics Support Force is statistically significant.The average annual outpatient drug consumption of retired military personnel is related to many factors.The problem of long-term over-medication of retired military personnel needs attention.
