The (GCT)o polymorphism of the MICA gene was investigated in 100 patients with latent autoimmune diabetes in adult (LADA) and 145 healthy controls by PCR and denaturing polyacrylamide gel electrophoresis.The A5.1 allele was present at a significantly higher frequency in LADA group (0.340) than that in control group (0.183) (P

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 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 establish bacterial endotoxin test for cardioplegic solution (compound jiagaimei solution).METHODS: Semi-quantitative analysis stated in volume Ⅱ of Chinese Pharmacopoiea (2005 edition) was used to detect 3 batches of compound jiagaimei solution with tachypleus amebocyte lysate (TAL).RESULTS: The interference factors of bacterial endotoxin test could be overcome through 6-fold dilution of cardioplegic solution.The content of bacterial endotoxin in 3 batches of samples were 0.36,0.36 and 0.255 EU?mL-1,respectively.They were all lower than the limitation of bacteria endotoxin of 1.5 EU?mL-1.CONCLUSION: It is feasible to detect bacterial endotoxin of compound jiagaimei solution using semi-quantitative analysis.

Objective To investigate the processing characteristics of locative prepositions in patients with Chinese aphasia,and to provide the theoretical evidence for the rehabilitation of aphasia.Methods Twenty aphasic patients caused by left-hemisphere stroke and twenty matched normal controls were studied.Using the locative prepo- sition repeating task(single words,locative preposition phrases and words in sentences),the comprehension task, filling-gap task,the visual-spatial function task and the short-term memory task,we compared the performance be- tween these two groups.Results The aphasic patients had more difficulty in repeating locative prepositions in sen- tences,in comprehension task and filling-gap task,their short term memory was impaired.Both groups did well in re- peating single words and phrases.Conclusion The processing of locative prepositions was impaired in Chinese aphasics.The repetition of locative prepositions was more difficult than that of phrases and single words.The preposi- tions were often omitted.It might be due to the impairment of their short-term memory,or it might have something to do with role they played in the syntactic structure.The latter might also impact the comprehension and filling-gap score.We should make plans before rehabilitation therapy.

Objective:To screen for the pathogenesis-related genes of osteosarcoma and to assess their roles for the de- velopment of osteosareoma.Methods:Total RNA was extracted from 3 ATCC osteosarcoma cell lines and an osteoblastic cell line and was used to synthesize biotinylated cRNAs;the latter were hybridized to Affymetrix~(?)GeneChip~(?)U133A ar- rays and a gene with more than 2 folds of change was selected.Ten of the differentially expressed genes were chosen and the primers were designed and the synthesized.Then SYBR~(?)Green real-time PCR(RT-PCR)method was used to detect the expression of the 10 genes in 9 fresh osteosarcoma specimens.ABI Prism 7 000 system was used to analyze the differ- ent expression between osteosarcoma cell line and osteoblastic cell line.Results:We identified 58 up-regulated and 142 down-regulated genes in the 3 osteosareoma cell lines.Many of the genes were firstly reported to be related to the patho- genesis of osteosarcoma.These differentially expressed genes were mainly involved in energy and material metabolism,on- cogene,signal transduction gene,transcription- related genes,cell cycle-related genes,cell apoptosis-related gene,im- mune response gene,tumor suppressor genes,etc.The array results of 10 randomly selected genes were further verified by the RT-PCR in 9 fresh osteosarcoma specimens.Conclusion:Many genes are involved in the pathogenesis of osteosarcoma. Gene microarray can help to discover the genes related to the pathogenesis of osteosarcoma,which may lay a foundation for studying the molecular mechanism of osteosarcom.

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.
