This paper reviewed benefit and risk of myopathy and rhabdomyolysis in statins with guide and following the medical evidence. The chemical structure of statins is closely related to the effect and heterogeneity of the drugs. The use of statins including atorvastatin, rosuvastatin can give patients more clinical benefit when strengthen to low blood lipid. Although rosuvastatin in statins is strongest, but presence of sulphonamide group resulted in the increase of its toxicity, It show that rosuvastatin risk for rhabdomyolysis was significantly higher than that of atorvastatin statins by foreign evidence. Therefore, the patients following with multiple risk factors need to use caution with the choice of rosuvastatin. Recently rosuvastatin causing myopathy and rhabdomyolysis cases in the world has increased, It should arouse the attention of clinical. Clinical pharmacists should focus more on pathophysiological state, interaction, drug genome science to proceed, so we can summarize and analyze the occurrence regularity, and investigate its mechanism in order to protect the safety of patients with medication. It can help clinical pharmacists to take responsibility for the uprising.

· AIM: This study was designed to evaluate the effectiveness of anterior lens capsule inclusion in combined trabeculectomy and cataract surgery in preventing scar formation of the filtering bleb in rabbit model.· METHODS: Twerty-Four eyes (12 rabbits) with glaucoma model were studied, anterior lens capsule inclusion in trabeculectomy with the small-incision cataract surgery were performed on all right eyes (experimental group) and no implants were applicator in trabeculectomy with the small-incision cataract surgery on all left eyes (control group). These operated eyes were followed up from day 1 to 6 months postoperatively. Intraocular pressure (IOP) was measured and filtering blebs were observed after surgery. Other main outcome measures: cornea、conjunctiva、formation of the anterior chamber, anterior chamber depth、inflammatory reaction、achievement ratio of operation and complications were analyzed. On week 1, 2, 4, 12 and 24 after surgery the animal were killed in batch. Tissue was harvested from the bleb area and was made pathological section. HE staining、light microscope and micro photo analysis technique were applied to observe the cytological and histopathologic characteristics of the filtering tunnels.· RESULTS: There were significant differences between the two groups on IOP (1, 2, 4 weeks)、filtration bleb, achievement ratio of operation and complications. In experimental group, at the first month postoperatively, anterior lens capsule absorption started with inflammatory characteristics. The peak of inflammatory reaction occurred 1 week after operation and all the cells in the filtrating tunnel disappeared 6month after surgery. The fibroblast proliferation in control group occurred at I week and the filtrating tunnel closed with angiogenesis at 1 month after surgery. Fibroblast proliferation started 1week after surgery with no statistical difference during the time course (P ＞0.05). Significant statistical differences were observed by comparing the fibro blasts numbers per unit area in the filtrating tunnel in experimental group and those in control groups (P＜0.05).· CONCLUSION: Anterior lens capsule was totally absorbed at 6 months postoperatively. Anterior lens capsule inclusion in trabeculectomy with cataract surgery can possibly control intraocular pressure effectively, long-term sustainability of functional filtration bleb, inhibition of the proliferation of fibroblasts and opening of the filtrating pathway in the experimental animal models were satisfied. Compared to the control group, anterior lens capsule application has less complication.
