Objective To verify the clinical applicability of the published standard intervals of routine clinical chemistry (WS/T404 .1‐2012 ,WS/T404 .2‐2012) based on the health examination results of Han and Uygur populations in Urumqi .Methods This was a retrospective study .The results of serum TP ,ALB ,ALT ,AST ,ALP ,GGT from healthy examination individuals of Han and Uygur populations (from 2013 August to 2015 January) were collected and the healthy cases (age range:20 -79 years old) were chosen to calculate the 2 .5% and 97 .5% percentiles ,excluding the significant abnormal results according to the Medical Deciding Level 2 recommended by Staland .The percents of health cases not falling in the published standard interval were calculated to meet the judgment criterion of verification (<10% ) .Results The test of normality revealed that the Han and Uygur's results of all veri‐fied items were skewed distributions .The 2 .5% and 97 .5% percentiles of the results of two populations were as follows ,TP(Han 65 -81 g/L ;Uygur 64-81 g/L) ,ALB(Han 41-53 g/L ;Uygur 40-52 g/L) ,ALT(Han:male 9-51 U/L and female 7-42 U/L ;Uygur:male 9-53 U/L and female 6-43 U/L) ,AST(Han:male 14-42 U/L and female 12-37 U/L ,Uygur:male 12-42 U/L and female 12-38 U/L) ,ALP(Han:male 45-119 U/L ;Uygur:male 47-122 U/L) ,ALP(female 20-49 years old:Han 35-95 U/L and Uygur 40-104 U/L) ,ALP(female 50-79 years old:Han 43-131 U/L and Uygur 51-132 U/L) ,GGT(Han:male 11-71 U/L and female 8-54 U/L ;Uygur :male 11 -73 U/L and female 7 -55 U/L ) .The percents of AST results for Han's male , Uygur's male and Uygur's female not falling in the published standard reference interval were slightly over 10% ,but AST results o‐ver 10% were mainly under the lower limit of the published standard reference interval .The health case percents for the other veri‐fied items of Han and Uygur populations not falling in the published standard reference interval were under 10% .Conclusion The published standard reference intervals of routine clinical chemistry (WS/T404 .1‐2012 ,WS/T404 .2‐2012) are applicable in our la‐boratory for the detection of Han and Uygur population .

Objective To provide the objective evidence for reducing stat test turnaround time (TAT) reasonably through the comparative analysis of different intervals of stat test TAT between emergency department (ED) and intensive care unit (ICU ) . Methods Laboratory information system was used to collect data about blood cell analysis and biochemical profiles of department of emergency and ICU from 1st January to 31th March ,2014 ,then comparatively analyzing different intervals of stat test TAT be‐tween two departments .Results TAT outlier rates of stat CBC tests ordered by ED and ICU were 2 .4% and 15 .1% ,and that of stat biochemical profiles ordered by ED and ICU were 12 .3% and 24 .5% ,respectively .there were no significant differences in mean times between order‐to‐receipt of stat CBC tests and biochemical profiles ordered by ED and collection‐to‐receipt of stat CBC tests and biochemical profiles ordered by ICU [(11 .2 ± 4 .0) min vs .(11 .2 ± 4 .5) min ,P>0 .05 ;(13 .2 ± 14 .1)min vs .(13 .8 ± 9 .8) min ,P>0 .05] .ED had significantly shorter mean time of receipt‐to‐report than ICU for stat CBC tests and biochemical profile [(5 .8 ± 4 .4) min vs .(19 .3 ± 12 .5) min ,P<0 .01 ;(34 .4 ± 10 .9) min vs .(35 .5 ± 13 .2) min ,P>0 .01] .The TAT mean times of stat CBC tests and biochemical profiles ordered by ED were shorter than those ordered by ICU [(17 .0 ± 6 .2) min vs .(30 .5 ± 14 .9) min ,P<0 .01 ;(46 .9 ± 17 .2) min vs .(49 .3 ± 16 .5) min ,P<0 .01] .Conclusion The ED TATs for CBC tests and biochemical pro‐files are reasonably set ,and each interval of the ED TATs is well controlled .The ICU TATs for CBCs and biochemical profiles should be reset ,and the process of stat test for ICU should be optimized .

Objective·To investigate the effects of a novel chitosan-silver nitrate gel (CSNG) dressing on anti-septic in wound healing.Methods·By using the ion membrane,the release rate of the new composite materials of silver ion was tested in vitro.Meanwhile,the anti-septic effects of CSNG on methicillin resistant Staphylococcus aureus (MRSA),Escherichia coli and Candida albicans were tested by colony counting.The rat wound healing model was used to detect the ability of new material to kill MRSA in vivo.Results·Compared with control group,the release of silver ions of CSNG was much slower.Sterilization experiment showed that CSNG killed the MRSA,Escherichia coli and Candida albicans much more efficiently,compared to that in the other treatments.Animal experiments also showed that CSNG promoted the rats of wound healing.Conclusion·Combining chitosan with silver nitrate and supplementary material could develop a novel chitosan-silver nitrate gel material,which not only has the obvious effects on antibacterial,but also on promoting wound healing.

ObjectiveRetrospectively investigate the characteristics of neoplasma of health checkup participants to find ways to improve cancer detection rate.Methods A total of 186 confirmed cancer patients were enrolled in this study.Personal information,including age,gender,andlocation were collected.The contribution of clinical symptoms,physical examination and laboratory test to cancer detection was investigated.ResultsBiopsy confirmed cancers accounted for 0.133%( 186/140 127 ).Lung (0.036% ),liver ( 0.017% ),kidney ( 0.014% ),colorectal ( 0.013% ) and gastric cancer ( 0.011% )were the most commonly found neoplasma.Detection rate of liver cancer in male was significantly higher than that in female (x2 =6.181,P<0.05 ).Asymptomatic cancer was found in 158 adults (84.9% ).Ultrasound showed a significantly higher sensitivity to liver,kidney and thyroid cancer than tumor biomarkers.The detection of lung cancer was improved with the combination of X ray,tumor marker( TM ),clinical symptom and low-dose chest CT scan.In 2008,the detection rate for digest system carcinoma (0.083% ) and lung cancer (x2 =8.538,P<0.05) was significantly increased (x2 =11.792,P<0.05).ConclusionsHealth check-up plays an important role in early detection of cancer.The combined use of physical examination,chest X ray,ultrasound test,TM and CT may improve the detection of cancer.

Objective:To explore the correlation between different smoking status and serum uric acid(SUA)in a middle-aged male in health check-up population.Methods:In this cross-sectional study, a total of 26701 middle-aged men who underwent health check-up in Taihu Sanatorium of Jiangsu Province from January 2014 to June 2015 were studied.The correlation between smoking status and SUA was analyzed by questionnaires, physical examination and serum biochemical assay.Smoking state was divided into no smoking, a occasional smoking and smoking groups.Results:With the increase of age, there was a downward trend of SUA( F=7.38, P=0.000). Among the three smoking groups, the group with occasional smoking had the highest level of SUA.The smoking group had lower level of SUA than the non-smoking group and occasional smoking group( P=0.000 and 0.005). In the non-smoking group, the fourth quartile of SUA(41.5%)had a higher percentage than that in first quartile of SUA(38.4%)( χ2=12.266, P=0.000). In the smoking group, the fourth quartile of SUA(54.9%)had lower percentage than that in the first quartile of SUA(58.4%)( χ2=7.049, P=0.008). Compared with the non-smoking group, the prevalence of hyperuricemia(HUA)in smoking group was lower( OR=0.872, 95% CI: 0.821~0.927, P=0.000), the prevalence of HUA in occasional smoking group was higher( OR=1.194, 95% CI: 1.013~1.408, P=0.035). Conclusions:As compared with the non-smoking group, the prevalence of HUA is lower in smoking group and is higher in occasional smoking group.
