Objective:To discuss the regularity of adverse drug reactions induced by statin.Method:82 cases from published articles were retrieved from 1998 to 2008.According to the given standard,the data were statistically analyzed. Result:77 articles carried 82 case reports concerning statins inducing ADRs in the period of 10 years.52 cases were caused by simvastatin.ADRs of statins could involve multiple organs and systems,mainly myopathys.Severe reaction could result in renal failure and even death.Conclusion:A rational use of statins should be strengthened in the clinical practice and strict monitoring in order to prevent and reduce the occurrence of serious adverse drug reactions.

Objective To summarize the clinical application of parenteral nutrition (PN) in Fuwai Hospital. Methods The clinical applications of PN in 132 critically ill patients undergoing cardiac surgery in our hospital were retrospectively investigated and analyzed. Results The application of PN in Fuwai hospital was basically appropriate and standardized. Energy supply in PN formulation was reasonably low, but still met the energy needs of patients in the fasting period. The nutritional composition and energy/nitrogen ratio in the formulation were basically rational. However, problems including the lack of double energy in partial formulation, low proportion of glucose-supplied energy due to low glucose-lipid ratio, and insufficient supply of insulin still existed. One (0.76%)patient was discharged according to his own decision; 22 ( 16.67% ) patients died, which were not directly associated with PN; and the other 109 (82.58%) patients were cured and discharged. Conclusion Application of PN for critically ill patients undergoing cardiac surgery must strictly follow the operation indications and rationally select nutritional components and proportions to ensure its safety and effectiveness.

Objective To elucidate the clinicopathological and hereditary characteristics in Fabry nephropathy.Methods The clinical and pathological features of 14 patients with Fabry nephropathy were collected.The activities of α-Gal A were measured in 4 probands.Screenings of GLA mutations were done in 12 patients.Results The ratio of Fabry nephropathy in the patients with renal biopsy was 0.074 ％ (14/19 005),the average diagnostic age was (30.57±9.32) years,male to female ratio was 2.5∶ 1.All the patients had proteinuria,and the median of urine total protein (UTP)was 1.71 g/24 h (0.32-4.71 g/24 h).Two of them got nephrotic proteinuria,5 of them got microscopic hematuria,4 of them got renal function insufficiency.Angiokeratomas was the most common manifestation (10/14),followed by cardiac involvement (6/14).Hypohidrosis and diseases of central neural system could also be seen in these patients.There were 9 classic phenotype,the remaining 5 were variants/renal variants.The family information was collected in 10 pedigrees,6 of them had family histories of kidney disease.Renal pathology showed vacuolization of glomerular visceral epithelial cells was the prominent feature,global and segmental glomerulosclerosis were seen in some patients by light microscopy.The myelin bodies or zebra bodies were identified in podocytes by electron microscopy,but only were found in some podocytes of 2 females.The activity of α-Gal A was decreased compared with the normal range in 4 probands.The mutations of GLA were demonstrated in 11 patients.Three novel mutations of GLA gene were identified,which were all deletion/insertion mutations with classic phenotypes.Most variants carried the mutations located in the buried/partial buried areas of α-Gal A (3/11).The classical phenotype carried GLA mutations as W162X,F169S,S201F,N272K,L310R,while variant phenotype carried GLA mutations as I91T,R112H,Q312H.Conclusions The ratio of Fabry nephropathy in patients with renal biopsy is 0.074％.Angiokeratomas and cardiac involvement are often accompanied with Fabry nephropathy.The genotypes of GLA may have close relationships with the phenotypes of Fabry nephopathy.

Objective To label the modified human epidermal growth factor receptor 2 (HER2) affibody with 68Ga at cysteine position of carboxyl-terminal Gly-Gly-Gly-Cys (GGGC) sequence,and to image the mice model bearing HER2-expressed breast cancer with microPET.Methods The HER2 affibody with carboxyl-terminal cysteine was produced by gene engineering.The 1,4,7,10-tetraazacyclododecane-1,4,7-tris-aceticacid (DOTA) was conjugated to the thiol (SH)-group of cysteine by DOTA-10-maleimidoethylacetamide (MMA-DOTA).The newly eluted 68Ga was labeled to DOTA-HER2 affibody at 90 ℃.The labeled mixture was purified by C18 cartridge and eluted with anhydrous alcohol.The purified 68Ga-labeled affibody was prepared for cell binding analysis and microPET imaging.The HER2-expressed breast cancer cells MBA-MD-361 were used to analyze cell binding and establish cancer model with BALB/c nude mice.68Ga-labeled affibody (3.7 MBq) was administered to 4 nude mice with breast cancer via tail vein for microPET imaging at 20 and 60 min post injection.The mice were sacrificed immediately after imaging in unconscious state and their tissue/organs (tumor,muscle,bone and heart) were removed for weighing and radioactivity counting by γ counter.The tumor to normal organ ratios of radioactivity (tumor to liver,muscle,bone and heart)were calculated.Results The purity of HER2 affibody was more than 95％.The radiochemical purity of 68Ga-labeled HER2 affibody was 97％.The KD value (affinity) of 68Ga-labeled HER2 affibody was 1.5 nmol/L in HER2positive cells.MicroPET imaging showed that 68Ga-labeled HER2 affibody could bind HER2-positive cancer rapidly and excreted mainly through urinary system.The radioactivity ratios of tumor to liver,muscle,bone and heart were 17.4±1.0,35.1±10.9,20.7±6.2 and 20.9±4.0,respectively.Conclusions 68Ga could be labeled to HER2 affibody.The 68Ga-labeled HER2 affibody may be useful for PET imaging of HER2-positive tumor.
