The discovery and utilization of anti-AIDS drugs therapy have not only increased lifespan, but also enhanced the quality of life of HIV infected people. However, limitations of currently available drug regimens and dosage forms often fail to effectively reduce the HIV viral load in the viral reservoirs in vivo. To overcome the drawbacks of present anti-AIDS drugs' dosage forms, engineered nanocarriers including polymeric nanoparticles, liposomes, solid lipid nanoparticles and dendrimers are developed to facilitate these drugs targeting to the HIV viral reservoirs. This article reviews recent advances in the field of targeting drug delivery systems for the treatment of AIDS.

Objective To explore the clinical indication and operative methods for different upper eyelid aging through perieyebrow incision.Methods We collected totally one hundred fifty-two cases in this study,including six males and 146 females,and aged from 26 to 80 years (average 47).There were 29 cases with only ptosis of upper eyelid,and the rest 123 cases were ptosis of upper eyelid with ptosis of eyebrow,sunken upper eyelid,bloated upper eyelid,or over-wide between eyebrow and eye region (compensatory eyebrow elevation).Through the incision of upper or lower margin of eyebrow,we treated these five types of upper eyelid aging by excision of redundant skin,orbicularis oculi muscle,frontal muscle,ROOF,or orbital fat,or ROOF elevation for upper eyelid rejuvenation.Results Patients were followed up for 3 to 120 months,with average 14.4 months.All ptosis of upper eyelid and over-wide between eyebrow and eye region patients were improved obviously.In 36 ptosis of upper eyelid with ptosis of eyebrow,seven of them treated with upper eyebrow margin incision got the best results;and the rest 29 patients treated with lower eyebrow margin incision,fifteen patients were lifted slightly,and the rest fourteen patients got no improvement.All scars of inferior eyebrow margin incision were invisible.Faded and applanate one millimeter wide scars were seen on two patients with superior eyebrow margin incision.In all patients with ptosis of upper eyelid,80％ patients with sunken upper eyelid were improved obviously,and 85 ％ with bloated upper eyelid were improved significantly.Conclusions Upper eyelid aging is divided into five categories.Upper eyelid aging could be corrected by perieyebrow approach.Our methods are simple,safe,fewer complications,and with short convalescence,which is the minimally invasive procedure recommended for Chinese patients with upper eyelid aging.

This research based on the analysis of spontaneous reporting system (SRS) data which the 9 601 case reports of Shuxuening injection adverse drug reactions (ADR) in national adverse drug reaction monitoring center during 2005-2012. Apply to the association rules to analysis of the relationship between Shuxuening injection's ADR and the characteristics of ADR reports were. We found that ADR commonly combination were "nausea + breath + chills + vomiting", "nausea + chills + vomiting + palpitations", and their confidence level were 100%. The ADR and the case reports information commonly combination were "itching, and glucose and sodium chloride Injection, and generally ADR report, and normal dosage", "palpitation, and glucose and sodium chloride injection, and normal dosage, and new report", "chills, and generally ADR report, and normal dosage, and 0.9% sodium chloride injection", and their confidence level were 100% too. The results showed that patients using Shuxuening injection occurred most of ADRs were systemic damage, skin and its accessories damage, digestive system damage, etc. And most of cases were generally and new reports, and patients with normal dosage. The ADR's occurred had little related with solvent. It is showed that the Shuxuening injection occurred of ADR mainly related to drug composition. So Shuxuening injection used in clinical need to closely observation, and focus on the ADR reaction, and to do a good job of drug risk management.
