Objective:To study the action of SH in mid-term cornea preservation.Methods:SH was added into mid-term preservation solution(MMK) to make the new storage media with SH of three different concentration (0.05%,0.03%,0.01%).The contrast group was MMK medium without SH.The corneal appearance,transparence and ultrastructure were observed,and trypan blue-alizarin red staining of CEC,SDH and G-6-P enzyme staining with histochemistry were made in different storage time.Results:The transparence of cornea and ultrastructure of CEC in all the experimental groups were better than that of the contrast.The activity degree of CEC was highest in group I,lowest in the contrast,and statistically significant among all the groups.Conclusion:SH plays an important role in protecting CEC in middle storage medium,and enhances the quality and prolongs the duration of the preserved corneas.The protective effect is determined by the consistence of SH.

Objective To analyze the concentration changes of serum hypoxia stress peptide (HSP)and plasma nitrogen monoxidum(NO)in the entering mountain rapidly man and to explore the importance of HSP and NO in adaptation of man to altitude hypoxia.Methods The levels of serum HSP and plasma NO2-/NO3-were measured from 106 entering mountain rapidly men,105 altitude in habitant,105 altitude immigrant and 104 plain healthy controls,respectively by chromatometry and NO2-/NO3-reagent.Furthermore,the content of serum HSP was determined in 106 entering mountain rapidly men,respectively at the time of 24 h,48 h,76 h,l week and 1 month after entering mountain.Results The level of serum HSP was significantly higher in entering mountain rapidly men than in habitant,immigrant and plain controls(P＜0.05),while there was no statistical difference between in habitant,immigrant and plain controls(P＞0.05).At 24h after entering mountain rapidly,the level of serum HSP was significantly increased and reached the peak.At 48h and 76h,it was slightly decreased,but still maintained a high level.At 1 week and 1 month,it gradually and significantly went down,but was still significantly higher than that in plain controls.Similarly,the level of plasma NO2-/NO3-was significantly elevated in entering mountain rapidly man,compared with inhabitant,immigrant and plain controls(P＜0.05).It was lower in inhabitants and immigrants than plain controls,but the difference was not statistically significant(P＞0.05).Conclusion The present results demonstrated that the levels of serum HSP and plasma NO were significantly up-regulated in healthy adults after en tcring mountain rapidly in order to adapt to altitude stress,and restored gradually to the normal level as time went by.

Objective The quantitation measurement of microalbuminuria was adopted to verify the feasibility of urinary microalbumin and ratio of mieroalbumin to creatinine (M/C) detection with dry hemieal method. Methods Totally 80 urine samples from the patients with clinically diagnosed dia-betes were tested by the immune quantitation method (immunoturhidimetric assay) and dry heroical method (HT2000 urine analyzer and test paper, Guilin Hnatong Company) simultaneously. Sarcosine oxidase method was applied to measuring creatinine level. Ten cases of outliers were removed. With the quantitation result of M/C as the reference standard, immune quatilyzation of the M/C as refer-ence, we compared and analyzed the results of the immune quantilization of urine microalbumin, those of the dry chemistry method and of the dry chemistry system detecting M/C. Results There was sig-nificant differences in test results of urinary microalbumin with the dry chemistry method and the im-mune quantitation method (P<0.01) The sensitivity, accuracy and Youden index of the microalbu-minuria testing had been observed to decrease in order in immune the dry chemistry method, the im-mune quantitation method and M/C quantitation detection method. Conclusion The sensitivity of semi-quantitation dry chemical method is satisfactory in detecting microalbumin, which may be used as a means of microalbumin screening. M/C detection with the dry chemical method isn't suitable for screening microalbumin in instant urine samples.

OBJECTIVE To perform a surveillance study in order to investigate the change in antimicrobial resistance of Klebsiella pneumoniae,especially extended-spectrum ?-lactamases(ESBLs)-producing strains isolated.METHODS A total of 1986 strains of K.pneumoniae isolated during the last six years were analyzed.RESULTS Among 1986 K.pneumoniae strains,908(45.7%) were ESBLs-producing strains.The sensitive rate of ESBLs-producing K.pneumoniae to imipenem was 100%,and to meropenem was 99%.There were 636 strains isolated from ICU,accounted for 32%;and 480 strains isolated from Department of Respiratory Medicine,accounted for 24.2%.There were 1630 strains isolated from sputum,accounted for 82.1%.CONCLUSIONS K.pneumoniae is the major pathogen.Detecting ESBLs-producing strains rate and their susceptibility to antibiotics is very important in guiding the clinical administration of drugs.

MicroRNA (miRNA) is newly discovered,a class of small non-coding RNA which plays critical roles in the regulation of gene expression at the posttranscriptional level by either degrading or blocking translation of messenger RNA targets.Growing evidence that some miRNAs have crucial roles in controlling and modulating immunity,while dysregulation of miRNAs can lead to autoimmunity,and miRNA-146 seems to be a popular topic discussed much.Thyroid associated ophthalmopathy (TAO) is an organ specificity autoimmune disease which is closely associated with Graves disease.Although many clinical and experimental investigations have been done,the precise aetiology and pathogenesis of TAO remain largely unclear.Here we review the roles of miRNA-146 regulation in immune functions and in the development of autoimmunity and autoimmune disease,and outlook for the roles of miRNA-146 in the pathogenesis of TAO.

Objective To analyze the risk factors of ANCA-associated systemic vasculitis with pulmonary infection to improve the alertness of clinicians to imprave the survival of patients.Methods Seventyfive AASV patients in Shanghai Renji Hospital from January 2010 to June 2013 were selected,and logistic regression models was applied to analyze the correlation.Results Of 75 AASV patients,39 (52％) cases were males,36(48％) cases were females,the average ages were (56±19),56(75％) cases were MPA,17(23％) cases were WG and 2(3％) cases were CSS.42(56％) cases were diagnosed to have pulmonary infection.Among the patients with pulmonary infection,23 (55％) were males,19 (45％) were females,24 (57％) were older than 60 years old,17(12％) had WG,37(88％) had MPA,and 8(19％) died.Meanwhile,11(26％) had bacterial infection,2(5％) had tuberculosis,2(5％) had fungi infection,and 27(64％) had mixed infections respectively.8(19％) cases died.Multivariate logistic regression analysis showed that those who were older than 60 years (OR=15.13,95％CI 2.16-106.04,P＜0.01),who were diagnosed as MPA (OR=9.00,95％CI 1.37-59.14,P＜0.05),who had hypoproteinemia (OR=17.61,95％CI 3.14-98.74,P＜0.01) and interstitial lung disease (OR=11.83,95％CI 2.19-63.85,P＜0.01) were more likely to complicate with pulmonary infection.Conclusion Those who are elders,diagnosed as MPA,with hypoproteinemia and interstitial lung disease have higher risk to have pulmonary infection among AASV patients,which underscores that clinicians should pay more attention to this complication of AAV patients.

Objective To study the dilution model of the early pregnancy test strip for the quantitative detection of serumβ-hu-man chorionic gonadotropin(β-hCG)level by the Abbot AxSYM detection system and its application.Methods The detection re-sults of serumβ-hCG level in 5 612 outpatients and inpatients of the internal medicine department and the gynecology and obstetrics department during 5 years were retrospectively analyzed.In addtion,234 serum samples from the patients were collected for prelimi-narily determining the serumβ-hCG level by the early regnancy test strip and then the quantitative detection of serumβ-hCG level was detected by the Abbot AxSYM detection system.Results The retrospective analysis showed that 241 cases(4.6%)were low-age pregnant women.The qualitative screening was necessary.The screening model was successfully established.But one thing to note was that the part of serum sample needed to be taken out and put into another tube for determination.Conclusion Establishing the rational and effective dilution interpretation model of early pregnancy test strip for screening serumβ-hCG can bring the econom-ic and time benifits for the routine detection work of the Abbot AxSYM detection system.
