Objective To investigate the association between nonalcoholic fatty liver disease (NAFLD) and metabolism or carotid intima-media thickness (CIMT) in Type 2 diabetic(T2DM). Methods According to the liver B-ultrasonography, a total of 321 T2DM patients were divided into two groups, with or without NAFLD. Metabolic indexes such as BMI, BP, blood glucose, blood lipid, uric acid ( UA ), insulin, C-peptipe,insulin resistance index(HOMA-IR) between the two groups were compared, and the relationships between alanine aminotransferase (ALT) and the above indexes were analyzed. Furthermore,the CIMT of the two groups were compared, and the relationships between NAFLD, ALT and CIMT were investigated by correlation and regression analysis. Results Compared with the group without NAFLD, the patients with NAFLD had higher level of BMI, triglyceride ( TG ), UA, fasting blood glucose ( FBG ), fasting insulin ( FIns ), fasting C peptide (FCP) ,HOMA-IR,and lower level of high density lipoprotein ( HDL-C ) significantly; BMI ( OR = 1.25, P ＜0. 001 ), TG ( OR = 1.74, P = 0. 008 ) and HOMA-IR ( OR = 2. 33, P = 0.010) were independent risk factors of NAFLD while H DL-C was independent protective factor; ALT was positively correlated with BMI (r = 0. 255, P ＜0. 001 ) ,TG(r =0. 156,P ＜0. 018) ,UA(r =0. 239,P ＜0. 001 ) ,FIns(r =0. 213,P =0. 001) ,FCP(r =0. 199,P ＜0. 003), HOMA-IR ( r = 0. 247, P ＜ 0. 001 ) and negatively correlated with HDL-C ( r = - 0. 199, P =0. 002) ,and BMI (β =0. 456,P =0. 048) ,UA (β =0. 021 ,P =0. 025) and HOMA-IR(β =3.634 ,P =0. 004)were independent associated facrors. The difference of CIMT between the two groups didn't reach statistical significance, while mutiple regression analysis revealed that ALT was independently associated with CIMT(β =0. 002,P = 0. 013). Conclusion T2DM patients with NAFLD show more serious disorder of metabolism and insulin resistance. ALT is an independent risk factor of CIMT in T2DM patients.

This study aimed to investigate the anti-apoptotic effects of Tangnaikang (TNK) on islet β cells in Zucker diabetic fatty (ZDF) rats.Six male fa/+ ZDF rats were took as the control group,while other thirty male fa/fa ZDF rats were divided into five groups at random:the model group,the metformin group,the high-,mediumand low-dose TNK groups,depending on their body weight and random blood glucose.Prior to the administration,fasting blood glucose and fasting insulin were measured by drawing blood with inner canthusl.Materials were prepared when administered for six weeks.Fasting blood glucose and fasting insulin were detected again.When the sections of the rat pancreatic tissue were embedded,the morphological changes of the islet were observed via HE staining,and the apoptosis of islet β cell were observed using TUNEL.Positive expression of Caspase-3,the transduction enzyme of cell death signal,was tested by immunohistochemical method.It was found that the fasting blood glucose of the (fa/fa) ZDF rats in the high-,medium-and low-dose TNK group was significantly improved after administration (P ＜ 0.01).The serum insulin of rats in the high-,medium-and low-dose TNK group arised compared with the model group,while the high-and low-dose TNK group showed differences in a statistical sense.Compared with the model group,the HOMA-IR of all the treatment group decreased,while significant difference was presented between the high-dose TNK group and the metformin group.HE staining showed that the morphology of the islet β cell of the rats in all the treatment group was improved.The results of TUNEL showed significantly apoptotic changes on islet β cell of the fa/fa ZDF rats.Compared with the model group,the positive expression of TUNEL in the metformin group and the high-dose TNK group were significantly reduced (P ＜ 0.05).The result of immunohistochemistry method showed that the protein levels of Caspase-3 in the metformin group and the high-dose TNK group decreased (P ＜ 0.05).In conclusion,it was demonstrated that TNK effectively reduced the apoptosis of islet β cells in fa/fa ZDF rats,which presented a protective effect.

Objective To investigate the precision, trueness, and accuracy of self-developed detection system in clinical chemistry.Methods This was a methodological evaluation.Take serum creatine kinase( CK) for instance, 6 serum sampleswith different leves ( on the upper or lower limit of the reference range or close to the medicine decide levels ( MDLs) , were collected for within-run precision( repeatability) and within-laboratory precision ( intermediate precision ) experiments.5 proficiency testing ( PT ) samples, 5 samples assigned value by reference method, and 40 fresh-frozen serums were measured and compared with reference method for trueness verification.Drawing method evaluation decision chart, calculating total errors and sigma level evaluation experiment based on the CV, bias, and allowed total errors(TEa)were used to evaluate the accuracy performance.The precision, trueness, and accuracy were compared with the quality indicators.Results The within-run precision and within-laboratory precision were less than the highest requirement of Chinese industrial standard.The mean bias was -8.96%, didn′t reachthe required standard (5.5%).After taking corrective actions, all samples but one ( -5.8%) met the required standard. Compared with the reference method, the mean bias on the MDLs was less than TEa.The performance points of the method evaluation decision chart indicated excellence performance.The total errors on MDLs were 14.2%, 10.4% and 7.6%, less than 15%.The sigma levels on MDLs were 5.9, 7.5 and 15, also achieved excellent level. Conclusions The precision, trueness, and accuracy performance of CK measured by self-developed detection system achieved excellent level of the Chinese industry standard, and the same results were found from different evaluation methods.

ObjectiveTo investigate the intelligence characteristics and relativity with motor development of children with spastic diplegia.MethodsIntelligence and motor development of 46 children with spastic diplegia were tested by Wechsler Intelligence Scale and Motor Development Milestone (MDM), to find out difference of intelligence between the children with diplegia and the normal control group.ResultsIntelligence quotient (IQ) of children with spastic diplegia was lower significantly than the normal control, specially performance IQ (PIQ). PIQ was related with motor development. The more delayed motor development was, the more lower PIQ was. Subtest scores of animal egg, puzzle, block design and picture generalization were lower in spastic diplegic children with normal IQ than that of the normal control group, while vocabulary IQ (VIQ) was not different.ConclusionThe intelligence structure of children with spastic diplegia is imbalanced and PIQ of those children is significantly lower than the normal children, which is related to hands-eyes correspond, sight-motor correspond and speed, and space-sight ability.

Objective To evaluate the effect of azithromycin on Pseudomonas aeruginosa PAO1 biofilm formation and virulence factors production. Methods Detect the minimum inhibitory concentration of azithromycin against PAO1 by 2-fold dilution method. Crystal violet staining assay was used for initial adhesion assays. The PAO1 biofilm was established in vitro and observed by scanning electron microscope. Viable bacterial counts were determined by serial dilution. LasB elastolytic activity was determined by using Elastin-Congo Red. Protease activity was determined by Azo-casein. Chloroform extraction method was used for pyoverdine assay . The orcinol assay was used to directly assess the amount of rhamnolipids . Results Scanning electron microscope biofilm and viable bacterial counts of PAO1 adhered to the surface of catheter in PAO1 azithromycin group were less than the PAO1 control group after incubated for 3 d and 7 d ( P ＜0.05), and the initial adhesion was weaker ( P ＜ 0. 05 ). The virulence factors production were obviously decreased (P ＜0.01 ). LasB elastolytic activity and pyoverdine were even reduced to the same as with the PA-JP3 group ( P ＞ 0.05 ), but the protease activity and the rhamnolipids concentration were higher than the PA-JP3 group ( P ＜ 0.05 ). Conclusion Azithromycin can inhibit PAO1 bioflim formation in vitro and virulence factors production.

ObjectiveTo explore the value of intraoperative contrast-enhanced ultrasonography in distinguishing gliomas,peritumorous cerebral edema and peripheral normal cerebral tissues,and grading cerebral gliomas.MethodsIntraoperative contrast-enhanced ultrasonic imaging in 80 patients diagnosed cerebral gliomas were studied retrospectively.The blood perfusion patterns of gliomas,peritumorous cerebral edema and peripheral normal cerebral tissues were observed closely after contrast and parameters were recorded.ResultsAfter contrast-enhanced ultrasound,peripheral normal cerebral tissues showed homogeneous enhancement,the tumor tissues and peritumorous cerebral edema of high-grade gliomas (HGG) showed high enhancement,but peritumorous cerebral edema of low-grade gliomas (LGG) showed nearly homogeneous enhancement.Absolute peak intensity(API) of the tumor tissues were higher than those of peripheral normal cerebral tissues and peritumorous cerebral edema ( P ＜0.05).Time to peak (TTP) of the tumor tissues in HGG were shorter than those of peripheral normal cerebral tissues and peritumorous cerebral edema ( P ＜ 0.05).TTP of the tumor tissues in LGG compared with those of peripheral normal cerebral tissues and peritumorous cerebral edema,two groups had no statistical significance ( P ＞ 0.05).ConclusionsIntraoperative contrast-enhanced ultrasonography can reflect the boundary of the brain edema,which is useful to guide surgical resection effectively and helpful to grade cerebral gliomas.

Objective To evaluate the clinical values of acoustic radiation force impulse(ARFI) elastography for liver fibrosis on hepatopath patients.Methods ARFI elastography was prospectively performed on 99 patients prepared to undergo hepatic surgery to get a shear wave velocity(Vs) which was the representative of liver stiffness.The fibrosis stages,inflammation grades and steatosis grades were evaluated histologically after surgery.Values of Vs were compared with the histological results.Results Values of Vs with fibrosis stage 0-4 was (1.14 ± 0.22) m/s,(1.30 ± 0.22) m/s,(1.36 ± 0.38) m/s,(1.47 ± 0.37)m/s and (1.87 ± 0.08) m/s,respectively.A significant difference was observed among them (P ＜0.001).There was a certain correlation between Vs and fibrosis stage(r =0.541,P ＜0.001).Vs was a significant predictor of stage ≥3 fibrosis with an area under the ROC curve of 0.812,sensitivity 73.2％ and specificity 81.4％ when 1.40 m/s was the cutoff value (P ＜ 0.001).Values of Vs with inflammation grade 0-3 was (1.17 ± 0.16)m/s,(1.43 ± 0.36) m/s,(1.59 ± 0.53) m/s and (1.89 ± 0.59) m/s,respectively,which were significantly different (P ＜ 0.001).A certain correlation was observed between Vs and inflammation grade(r =0.383,P ＜0.001).Values of Vs with steatosis grade 0-4 was (1.61 ±0.42) m/s,(1.47±0.58) m/s,(1.56 ± 0.71)m/s,1.13 m/s and (0.94 ± 0.95) m/s.Obvious difference didn't exist between Vs and steatosis grade (P =0.286).Obvious correlation wasn't observed between them,either (r =-0.177,P =0.080).Conclusions ARFI elastography has a certain value for the evaluation of liver fibrosis,while inflammation grade may affect its performance.

ObjectiveTo evaluate analytical performance of NT-proBNP on Electro-Chemiluminescence Immunoassay system.MethodsThe precision,accuracy,limit of blank ( LoB ),limit of detection (LoD),functional sensitivity (FS),analytical measure range (AMR),maximal dilution rate,clinical reportable range(CRR) and the analytical anti-interference ability of NT-proBNP were evaluated according to EP documents issued by CLSI and related references.The analytical performance data were compared to quality standards declared by the manusfacturers.According to CLSI C28-A2,80 healthy volunteers,aged from 18 to 74, were chosen and divided into 4 groups on average for biological reference intervals verification.Results The within-run CV and total CV were 1.1％ -2.2％and 1.5％ -2.9％ respectively.The deviations from controls distributed by National Center for Clinical Laboratory and affiliated calibrators were 2.7％ -5.9％ and 2.7％ -7.5％,respectively.The results of LoB,LoD and FS were 2.5,7.8 and 8.8 pg/ml,respectively.AMR was 8 -35 126 pg/ml,and the most suitable dilution rate was 1∶ 2,so the CRR was 9 -70 252 pg/ml.428 μmol/L bilirubin,2 g/L haematoglobin and 2 200 FIU chyle didn't interfere with the NT-proBNP assay.Moreover,almost all the data from different age groups were in the range of biological reference intervals declared by the manusfacturers, except one test data (167 pg/ml).Conclusions The analyticalperformance of NT-proBNP analyzed on Roche Cobas E601electrochemiluminescence immunoassay systemisconsistentwiththestandarlswhichmanufacturershas proclaimed.The establishment of LoD,FS,maximal dilution and CRR for NT-proBNP assay could provide the quality assurance for clinical use and the biological reference intervals declared by manusfacturers could meet the clinical needs.

Objective To explore the ultrasonographic characteristics of internal jugular vein(IJV) valve insufficiency and reflux.Methods 40 healthy volunteers' bilateral IJVs were study subjects.The inner diameter,valve morphological feature,reflux distance and hemodynamic parameters in IJV were detected by color Doppler ultrasound (CDU),the contrast agents transvalvular regurgitation in IJV was monitored by contrast-enhanced ultrasound (CEUS) (with low mechanical index,MI 0.10),then analyse the results of two methods.Results Of 80 investigated IJVs,1 vein was excluded due to absence of its left valve,so 79 veins were evaluated in the study.The IJV's inner diameter on the right side was larger than on the left side,but there was no significant difference (P ＞0.05).The detection rate of IJV valve insufficiency was 31.6％ (25/79),which was higher on the right than that on the left,but without significant difference (P ＞ 0.05).The detection rate of IJV valve insufficiency was significantly higher in the group of greater than or equal to 50 years old than that in less than 50 years old(P ＜0.05).The reflux distance in IJV displayed by CDU was associated with IJV valve's function.Compaired with sufficient valves,the reflux duration time in insufficient valves during quiet respiration showed no significant difference (P ＞0.05).During Valsalvalike manoeuvres and quiet respiration,the reflux duration time in sufficient valves showed no significant difference (P ＞ 0.05).The reflux duration time in insufficient valves during Valsalva-like manoeuvres showed significantly higher than that during quiet respiration (P ＜0.01).Compaired with sufficient valves,the peak flow velocity of reflux flow in insufficient valves was significantly prolonged during quiet respiration and Valsalva-like manoeuvres (P ＜0.05,P ＜0.01,respectively).Conclusions The incidence rate of IJV valve insufficiency and reflux is high in healthy individuals.During quiet respiration and/or Valsalva-like manoeuvres,detecting the reflux distance,reflux duration time and peak flow velocity of reflux flow by CDU are valuable in evaluating IJV valve insufficiency and the degree of IJV reflux.
